Garden spheres in different sizes add a touch of whimsy to a garden area or sitting area to make a focal point in your landscape design. This do-it-yourself project is inexpensive and uses metal wire to form the sphere frame. Making various sizes of garden spheres and painting them in an array of colors allows you to make accents that are truly your own.

Things You’ll Need

18-gauge galvanized steel wire

Aerosol paint primer (optional)

Aerosol outdoor paint (optional)

Step 1

Blow up helium balloons into a variety of sizes by inflating some entirely and others partially. Tie a knot in the open end of each balloon to retain the air inside.

Step 2

Pull the loose end of 18-gauge galvanized steel wire from a roll and use needle-nose pliers to bend the end into a hook. Place the hook on the top of the balloon’s knot.

Step 3

Wrap the wire to the bottom of the balloon, shaping it around the circumference of the balloon. Wrap the wire upward around the balloon, making the two wires about 1/2 inch apart and back down. Continue wrapping wire and shaping it around the balloon until you cover it with wires about 1/2 inches apart in all directions.

Step 4

Cut the wire with wire cutters after making the last wrap and ending it at the top of the hook on the first wire wrap. Bend a hook into the cut piece of wire, connect the two hooks together and squeeze them together tightly with needle-nose pliers.

Step 5

Prick the balloon between the wires with a needle to break it. Pull the broken balloon from between the wires with needle-nose pliers.

Step 6

Lay a thick layer of newspaper on the ground outside. Place your garden spheres on the newspaper, spray them with aerosol paint primer, allow it to dry and then add aerosol outdoor paint to them for a brightly colored project.

Step 7

Add a length of twine to the top of the spheres to hang them from trees.

Galvanized wire will not rust, so you can leave the garden spheres in the natural bright wire color if you wish.

Garden spheres are decorative when lying singly or in groupings among plants on the ground.

Helium balloons are much thicker than regular balloons and hold air better while shaping the wire around them.

An inverter provides power backup for mains-based appliances in the event of a power failure. Most of the inverters available in the market have complicated circuit design and are not very economical. Some of them produce a square-wave output, which is undesirable for inductive loads. The project is a simple sine wave inverter circuit that produces 50Hz quasi-sine wave output using a single IC CD4047 and some discrete components, which makes it a very cost-effective solution.

Fig. 1 shows the sine wave inverter circuit of the MOSFET-based 50Hz inverter. It comprises a CD4047 multivibrator (IC1), IRF250 MOSFETs (T1 through T8), transistors and a few discrete components.

IC CD4047 has built-in facilities for astable and bistable multivibrators. The inverter application requires two outputs that are 180 degrees out of phase. Therefore IC1 is wired to produce two square-wave output signals at pins 10 and 11 with 50Hz frequency, 50 per cent duty cycle and 180-degree phase-shift. The oscillating frequency is decided by external preset VR1 and capacitor C1.

How to Create a Spiral with Heart Center of Sinewave SpheresFig. 1: Sine wave inverter circuit

How to Create a Spiral with Heart Center of Sinewave SpheresThese two signals drive the two MOSFET banks (bank-1 and bank-2) alternatively. When pin 10 of IC1 is high and pin 11 low, MOSFETs of bank-1 (T1 through T4) conduct, while MOSFETs of bank-2 (T5 through T8) remain in the non-conducting state. Therefore a large swing of current flows through the first half of the primary winding of inverter transformer X1 and 230V AC develops across the secondary winding.

During the next half cycle, the voltage at pin 10 of IC1 goes low, while the voltage at pin 11 is high. Thus MOSFETs of bank-2 conduct, while the MOSFETs of bank-1 remain non-conducting. Therefore current flows through the other half of the primary winding and 230V AC develops across the secondary winding.

This way an alternating output voltage is obtained across the secondary winding.

The sine wave output is obtained by forming a tank circuit with the secondary winding of the inverter transformer in parallel with capacitors C5 through C7. Two 2.2µF capacitors are connected to the gates of the MOSFETs in both the banks with respect to the ground if proper sinewave is not produced. Natural frequency of the tank circuit is adjusted to 50 Hz. Current consumption with no load is only 500 mA due to 50 per cent duty cycle of the square-wave signal. As the load is increased, current consumption increases.

The supply voltage to IC1 is limited to 5.1 volts by using zener ZD1 and resistor R4 with the external battery as shown in Fig. 1.

Low-battery indicator

The low-battery indication circuit consists of transistor T9, preset VR2, zener diode ZD2, resistors R5, R6 and R7, LED2 and capacitor C2. The 12V supply voltage from BATT.1 is applied to the low-battery indicator circuit with full load (not more than 1000 watts) connected to the inverter output. The voltage across the load is 230V AC. At this instant, adjust preset VR2 such that zener diode ZD2 and transistor T9 conduct to drop the collector voltage to 0.7 volt keeping LED2 ‘off.’

If supply voltage goes below 10.5 volts, the voltage across the load decreases from 230V AC to 210V AC. At this instant, zener diode ZD2 and transistor T9 do not conduct and hence the collector voltage increases to about 10.5 volts and LED2 glows to indicate low voltage of the battery. At the same time, piezobuzzer PZ1 produces an audio tone indicating low battery.

Low-battery cut-off

If the battery is discharged to zero volt repeatedly, the battery life will decrease. The low-battery cut-off circuit consists of transistor T10, preset VR3, zener diode ZD4, resistors R8 and R9, capacitor C3 and diode D1.

Adjust preset VR3 such that when the voltage across the load is above 200 volts, zener diode ZD4 and transistor T10 conduct. The collector voltage of T10 is about 0.7 volt in this case and hence the SCR (SCR1) will not conduct.

But if the voltage across the load goes below 200 volts, zener diode ZD4 and transistor T10 will not conduct and the collector voltage of T10 will increase, causing the SCR to conduct.

Once the SCR conducts, the supply voltage to IC1 (CD4047) will be 0.7 volt, due to which IC1 will be unable to produce the voltage pulses at output pins 10 and 11 and the inverter will turn off automatically. During this state, the SCR remains conducting.

Low cut-off of the inverter can be set at the load voltage of 170 volts for tubelight, fan, etc. So the tubelight and fan will not be switched off until the voltage goes below 170 volts.

No-load cut-off

If there is no load connected at the output of the inverter, the output voltage is 270 to 290 volts. This voltage is sensed by the 0-12V tap at the secondary winding of inverter transformer X1, which is connected to the no-load cut-off circuit comprising zener diode ZD5, transistor T11, preset VR4, resistors R12 and R11, and capacitor C4.

When no load is connected, the voltage at 12V tap will also increase. This voltage is rectified by the full-wave bridge rectifier comprising diodes D3 through D6, filtered by capacitor C4 and given to transistor T11.

Adjust preset VR4 such that if the inverter voltage goes above 250 volts, zener diode ZD5 and transistor T11 conduct. This increases the emitter voltage, hence the SCR fires to switch the inverter ‘off.’ When proper load is connected, the inverter will automatically turn on.

Construction

An actual-size, single-side PCB for the sine wave inverter circuit is shown in Fig. 2 and its component layout in Fig. 3. Suitable connector CON1 is provided on the PCB to connect the MOSFET banks and the transformer externally. Connector CON1 pins A through F are also marked on schematic. Assemble the circuit on a PCB as it saves time and minimises assembly errors. Carefully assemble the components and double-check for any overlooked error. MOSFETs should be mounted over heat-sinks using mica spacers as the insulators between them.

Connect the 24V supply terminal directly to the centre tap of the primary winding of the inverter transformer, which carries maximum current of more than 50 amperes with 1000 watts. Current depends on the load applied. There is no need to add a switch in the high-current path to make the inverter turn on and off. The inverter can be switched on and off by low-current switch S1.

Your body naturally makes mucus every day, and its presence isn’t necessarily a sign of anything unhealthy. Mucus, also known as phlegm when it’s produced by your respiratory system, lines the tissues of your body (such as your nose, mouth, throat, and lungs), and it helps protect you from infection.

Your body makes about a liter of mucus a day. But too much of it, especially somewhere like your lungs, can be annoying and possibly a sign of a health problem. Here are a few situations when you might get mucus in your chest:

Acid Reflux

If you have acid reflux, the acid in your stomach comes up the esophagus to your throat. This can result in throat irritation and postnasal drip, along with chest congestion.

Allergies

Allergies can cause a host of symptoms, from itchy eyes and sneezing to congestion, chest tightness, and coughing. A reaction that involves the lungs is more typical if you’re allergic to something airborne, such as pollen or dust mites.

Asthma

Along with other symptoms of asthma, such as shortness of breath and chest tightness, asthma can cause you to cough up phlegm. This may be a sign that your airways are inflamed, but small amounts of white or clear mucus aren’t worrisome.

Bacterial and Viral Infections

Infections such as the flu, acute bronchitis, and pneumonia can cause your airways to make extra mucus, which you’ll often cough up. It may be green or yellow in color.

The new coronavirus that causes COVID-19 doesn’t usually cause mucus in the chest. But complications from the virus can include pneumonia, which does involve chest congestion.

Chronic Obstructive Pulmonary Disease (COPD)

COPD includes several lung diseases that can make it harder to breathe, including chronic bronchitis and emphysema. Chronic bronchitis causes inflammation of the bronchial tubes and more mucus, both of which make it harder for your lungs to work. COPD is generally caused by long-term exposure to things that irritate the lungs, such as cigarette smoke, but people with asthma can also develop it.

Continued

Cystic Fibrosis

This is an inherited disease that results in thick mucus in the lungs and other organs. It can lead to worsening lung function as people age. Doctors test for cystic fibrosis (CF) in newborns, and 75% of people with CF are diagnosed by age 2. A parent can pass on the CF gene even if they don’t have the condition themselves, and about 1,000 new cases of CF are diagnosed annually in the U.S.

What You Can Do at Home

To control or loosen mucus at home, you can try the following remedies:

Drink lots of fluids. Drink plenty of water and other fluids, but not things that can dehydrate you, such as coffee and alcohol.

Humidify. Try a cool mist humidifier or hop into a steamy shower to keep your airways moisturized.

Don’t smoke or vape anything. Whether from tobacco or marijuana, smoke is an irritant and can cause your body to make more mucus.

Try a teaspoon of honey. Though honey doesn’t get rid of mucus, it can calm your cough temporarily. (Don’t give honey to anyone under 1 year of age.)

Check air filters. Other irritants in the air can make mucus production worse, so make sure your heating and cooling system filters are clean and up to date.

Take an expectorant. Some cough medicines contain guaifenesin, which loosens mucus so you can cough it up.

When to Seek Help

On its own, mucus isn’t a worrisome symptom. If it comes with a cough that doesn’t go away after several weeks, it’s greenish yellow or blood-tinged, or you also have fever or shortness of breath, you should call your doctor.

Cutting shrubs with dense growth such as boxwood into ornamental shapes is an art known as topiary. Topiary shapes range from simple spheres, cones and squares to fanciful designs such as peacocks, bears and even faces. Incorporating a topiary shrub into a landscape gives it a structural element that helps to balance strong architectural elements such as a heavy fence or wall. Though pruning topiary may seem intimidating, it can actually be quite simple.

Set out your tools in advance so that they will be handy when you need them. Tools for trimming topiary include long-handled shears for cutting rough shapes and hand shears for cutting fine detailed shapes.

Mix a solution of one part bleach and nine parts water in a bucket. Soak a sponge in this solution and wipe the blades of your tools with it. This will sterilize the tools. Use this solution in between trimming each shrub to avoid the spread of diseases.

  • Cutting shrubs with dense growth such as boxwood into ornamental shapes is an art known as topiary.
  • Use this solution in between trimming each shrub to avoid the spread of diseases.

Schedule your first topiary training session for spring after all danger of frost has passed. Topiary should be maintained with regular trimming every three months from spring until fall. Never remove more than 1/3 of your topiary plant’s total size during initial training. For complex topiary, gradually shape the plant over time by removing a little bit of the shrub during each training session.

Choose a shrub to make into your topiary that already has a similar shape. For example, if you are making your topiary into a cone, choose a boxwood that already has a pyramid shape.

Create a rough-cut shape with long-handled shears. Select a reference point on the plant to work from. For example, if you are making a cone, work outward from a central stem. If you are cutting a spiral, wrap a string in a spiral around the bush to form a guide line.

  • Schedule your first topiary training session for spring after all danger of frost has passed.
  • For complex topiary, gradually shape the plant over time by removing a little bit of the shrub during each training session.

Step back from your topiary plant after making each cut to assess whether you are trimming the plant properly.

Create a wire template to help you with fine trimming for your shrub. If you are trimming a shrub into a cone, create a straight guide that you can hold against the slope of the shrub to determine that the surface of the cone is uniform. Trim any branches that grow beyond the level of the template with your hand shears. If you are creating a round ball, bend the wire into a sphere. Hold the sphere against your shrub and trim any branches that grow outside of the circle.

    Abstract

    The mechanisms underlying the association between positive emotions and physical health remain a mystery. We hypothesize that an upward-spiral dynamic continually reinforces the tie between positive emotions and physical health and that this spiral is mediated by people’s perceptions of their positive social connections. We tested this overarching hypothesis in a longitudinal field experiment in which participants were randomly assigned to an intervention group that self-generated positive emotions via loving-kindness meditation or to a waiting-list control group. Participants in the intervention group increased in positive emotions relative to those in the control group, an effect moderated by baseline vagal tone, a proxy index of physical health. Increased positive emotions, in turn, produced increases in vagal tone, an effect mediated by increased perceptions of social connections. This experimental evidence identifies one mechanism-perceptions of social connections-through which positive emotions build physical health, indexed as vagal tone. Results suggest that positive emotions, positive social connections, and physical health influence one another in a self-sustaining upward-spiral dynamic.

    The fully operational hydropower stations across China’s landscape currently produce more electricity than the electric grids present in any other nation. The two most recent and impressive additions to China’s collection of hydropower stations are managed by the China Three Gorges Corporation.

    China Three Gorges Corporation is a state-owned power company in China. The corporation is most known for (and named after) their most famous project – The Three Gorges Dam. The Three Gorges Dam became fully operational in 2008, and still stands today as one of the world’s largest hydroelectric power plants.

    The most recent project completed by China Three Gorges Corp. is the Wudongde Hydropower Station. As of June 29, the first unit of the Hydropower Station – China’s fourth largest and world’s seventh largest station – is now in operation. The station has a capacity of 10.2 million kilowatts and an average annual generating capacity of 38.91 billion kilowatts.

    Due to its large size, the Wudongde Hydropower Station has the ability to block the Yangtze River Basin and create a reservoir that stores 7.4 billion cubic meters of water. Uniquely, the architecture of the station resembles a delicate eggshell shape, and has been officially classified as the world’s thinnest 300-meter dam. By utilizing this station, China avoids the necessity of using an estimated 12.2 million tons of coal while producing more energy than the produced by all hydropower stations currently present in the Philippines.

    A bit further downstream from the Wudongde station sits the second most recent project by the China Three Gorges Corporation: the Baihetan station. Similar in size and operational qualities to the Wudongde station, the Baihetan is projected to be operational sometime in 2021 and reach full capacity in 2022.

    Since the beginning of the century, China’s hydropower projects have allowed the country to quadruple its installed capacity and account for over half of global growth in the hydropower industry. With the Wudognde and Baihetan stations completion, China will have completed the construction of five of the world’s largest hydropower stations in 10 years. The completion of these two hydropower stations has marked the end of a mega-dam building era in China’s history.

    Large hydropower stations require substantially large amounts of flowing water that travel down a path of steep altitude. Since China has utilized most of the suitable locations for large projects, any potential hydropower projects in the future will have to be adjusted to smaller sizes. The only locations left are 10-gigawatt-sized dams that are currently being constructed and established in permits, and are either unsuitable for mega-dams in size or terrain for a large mega-dam construction project.

    If China continues to build their hydropower industry further, the future projects will be 1-3 gigawatt sized stations to accommodate the size of remaining natural water resources and environments. Smaller projects of hydropower are typically classified as pumped-hydro projects because of their ability to provide storage space for intermittent renewable energy.

    With this shift in available space the trajectory for mega-dam hydropower projects is expected to reduce rapidly across China’s soil. Local attention in China’s renewable energy industry is shifting towards cheaper options, like solar development projects. These alternatives are less expensive and still provide beneficial returns of investments.

    “It’s so cheap developing renewables and coal-fired power, why bother injecting huge sums of money to develop hydro 2,000 kilometers deep in the Tibetan plateau,” said Frank Yu, an analyst with Wood Mackenzie Ltd. “The future of hydro is going to be pumped storage and is also going to be smaller and smaller.”

    However, China has recognized their success and abundant electricity generation from their hydropower stations, and the country has already decided to expand this industry on an international scale. Chinese hydro companies are heavily investing in potential projects overseas, and recent plans with Pakistan have circulated across several news outlets.

    The nation certainly has the funding to see these construction endeavors through. According to the Boston University Global Development Policy Center, major development banks in China have financed nearly $44 billion worth of hydropower projects globally since 2000. If international neighbors agree to allow China to construct more stations on their soil, then maybe the hydropower industry of China will not face a downward spiral after all. Projects will continue to drop in size, and public opposition, a long foe of development of large hydro, may lessen as well.

    It couldn’t be easier to create and manipulate shapes in Adobe Illustrator. The best part is that they’re live shapes that remain editable with a drawing tool.

    Create rectangles, squares, and diamond shapes

    Select the Rectangle tool, and before starting, set your fill and stroke colors in the Properties panel.

    Drag on the artboard to create a rectangle. Drag until you see a diagonal magenta line to create a perfect square. As you drag, you’ll notice an onscreen tooltip next to the pointer that shows the dimensions.

    Move the pointer slightly away from the bounding box to see a curved arrow. Now drag to rotate your square to any angle; press Shift to constrain the rotation to 45° to create a diamond shape.

    You can scale a shape by dragging any of the eight bounding box handles, and you can easily reset the rotation angle, change dimensions, and make other changes in the Transform section of the Properties panel (Window > Properties).

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Create a triangle and other polygonal shapes

    Now press and hold the Rectangle tool in the Toolbar to view other nested shape tools and select the Polygon tool.

    One way to start a shape is to simply click on the artboard and enter the number of sides — for example, type 3 to create a triangle, or 5 to create a pentagon.

    Change your shape’s dimensions by dragging the bounding box handles; press Shift while dragging to constrain proportions.

    You can easily manipulate these shapes to create non-uniform polygons. Click outside so nothing is selected, and then use the Direct Selection tool to select a control point and drag to transform the shape.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Create a circle, oval, and organic shapes

    Now select the Ellipse tool in the same set of nested tools and drag to create an oval of any size. Look for the magenta crosshairs to create a perfect circle. Alternatively, press Shift while dragging to make it a circle.

    Click outside to deselect, and then use the Direct Selection tool to manipulate your elliptical shape to create organic variations to use in your designs.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Now that you’ve learned how to create a few simple shapes, practice your skills and use these foundational shapes to create more complex artwork.

    In a world where everything consists of squares and cubes, creating anything that’s perfectly round in your Minecraft world is impossible. But if you have your heart set on circles or spheres, here’s a trick: You can come close by stacking blocks.

    Constructing a circle

    Building a circle relies on techniques similar to those used when building with slanted lines — you make both with small segments of blocks.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    To build a circle like this one, follow these steps:

    Construct the longest line segment.

    It should be, at most, 1/3 the length of the circle’s diameter.

    Construct a shorter line segment just behind the first one.

    Continue making shorter lines, with the difference being smaller and smaller each time.

    This step composes the arc at the top of the circle.

    Turn around and repeat.

    When you estimate a circle in Minecraft, it should have 4-way symmetry: Whether you’re looking north, south, east, or west, the circle should look the same. Thus, the process of constructing each side of the circle is exactly the same.

    Fix any lopsidedness.

    If a segment looks too long, destroy a block at the end and extend the adjacent segment to fill the gap. If a segment looks too short, just do the same thing in reverse.

    Even though you can’t get a truly round circle, any rounded room tends to have the same effect.

    Constructing a sphere

    Spheres are much trickier to build than circles — it’s a lot more difficult to estimate a three-dimensional rounded object than a flat one. However, there’s a clever way you can build a sphere:

    Build a flat circle whose diameter is the same as your sphere’s diameter.

    This is the ring that will go around the middle of your sphere.

    Build two more circles in the same way, except that these circles are vertical (with their diameter perpendicular to the ground) and surround the sphere lengthwise and widthwise.

    The result should be a cluster of three rings, each of which intersects the others twice.

    Fill out the sphere by building extra circles parallel to the first one, using the second and third circles as guides.

    Spheres can be used for all sorts of things — dome-shaped roofs, balloons, and blimps are just a few. Three-dimensional rounded objects are useful for making structures smoother and more elegant.

    The term sacred geometry describes the geometrical laws which create everything in existence. It unites the mind and the heart, spirit and matter, science and spirituality. Everything in nature is made up of patterns, structures, and designs from the smallest atom to the infinite universe. Each of nature’s creations reveals to us the nature of that object and its own energetic vibration. Thus every creation has a unique vibratory frequency. The interaction of all the vibratory frequencies found in creation show us the intrinsic unity of the part to the whole.

    The general belief behind sacred geometry is that geometry and mathematical ratios, harmonics and proportion are also found in music, light, and cosmology. This value system is seen as widespread even in prehistory, a cultural universal knowing of the human condition. It is considered foundational to building sacred structures such as temples, mosques, megaliths, monuments and churches; sacred spaces such as altars, temenoi and tabernacles; meeting places such as sacred groves, village greens and holy wells and the creation of religious art, iconography and using “divine” proportions. Alternatively, sacred geometry based arts may be ephemeral, such as visualization, sandpainting and medicine wheels.
    How to Create a Spiral with Heart Center of Sinewave Spheres
    Sacred geometry may be understood as a worldview of pattern recognition, a complex system of religious symbols and structures involving space, time and form. According to this view the basic patterns of existence are perceived as sacred. By connecting with these, a believer contemplates the Great Mysteries, and the Great Design. By studying the nature of these patterns, forms and relationships and their connections, insight may be gained into the mysteries – the laws and lore of the Universe.

    The discovery of the relationship of geometry and mathematics to music within the Classical Period is attributed to Pythagoras, who found that a string stopped halfway along its length produced an octave, while a ratio of 3/2 produced a fifth interval and 4/3 produced a fourth. Pythagoreans believed that this gave music powers of healing, as it could “harmonize” the out-of-balance body, and this belief has been revived in modern times.

    Hans Jenny, a physician who pioneered the study of geometric figures formed by wave interactions and named that study cymatics, is often cited in this context.

    At least as late as Johannes Kepler (1571-1630), a belief in the geometric underpinnings of the cosmos persisted among scientists. Kepler explored the ratios of the planetary orbits, at first in two dimensions (having spotted that the ratio of the orbits of Jupiter and Saturn approximate to the in-circle and out-circle of an equilateral triangle). When this did not give him a neat enough outcome, he tried using the Platonic solids. In fact, planetary orbits can be related using two-dimensional geometric figures, but the figures do not occur in a particularly neat order. Even in his own lifetime (with less accurate data than we now possess) Kepler could see that the fit of the Platonic solids was imperfect. However, other geometric configurations are possible.

    How to Create a Spiral with Heart Center of Sinewave SpheresNatural Forms

    Many forms observed in nature can be related to geometry (for sound reasons of resource optimization). For example, the chambered nautilus grows at a constant rate and so its shell forms a logarithmic spiral to accommodate that growth without changing shape. Also, honeybees construct hexagonal cells to hold their honey. These and other correspondences are seen by believers in sacred geometry to be further proof of the cosmic significance of geometric forms. But some scientists see such phenomena as the logical outcome of natural principles.

    Art and Architecture

    The golden ratio, geometric ratios, and geometric figures were often employed in the design of Egyptian, ancient Indian, Greek and Roman architecture. Medieval European cathedrals also incorporated symbolic geometry. Indian and Himalayan spiritual communities often constructed temples and fortifications on design plans of mandala and yantra. For examples of sacred geometry in art and architecture refer:

    • Labyrinth (an Eulerian path, as distinct from a maze)
    • Mandala
    • Flower of Life
    • Parthenon
    • Taijitu (Yin-Yang)
    • Tree of Life
    • Rose Window
    • Celtic art such as the “Book of Kells”
    • Yantra
    • Swastika
    • Dharmacakra
    • Vesica piscis
    • Metatron’s Cube

    Contemporary Usage

    A contemporary usage of the term sacred geometry describes assertions of a mathematical order to the intrinsic nature of the universe. Scientists see the same geometric and mathematical patterns as arising directly from natural principles.

    Some of the most prevalent traditional geometric forms ascribed to sacred geometry include the sine wave, the sphere, the vesica piscis, the 5 platonic solids, the torus (donut), the golden spiral, the tesseract (4-dimensional cube), and the merkaba (2 oppositely oriented and interpenetrating tetrahedrons).

    Feng shui tips to ground the challenging staircase energy

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Ryan McVay / Getty Images

    A staircase in itself is not bad feng shui. You need a staircase in a house with several levels, but the idea is to make the energy as harmonious as possible.

    The so-called bad feng shui reputation of staircases is similar to bathrooms, Both are needed, and both can contribute to good feng shui energy in your home. The feng shui concern with staircases is that a staircase typically creates a quality of unsettling energy, Depending on the energy flow in a specific home (as determined by its floor plan), this unsettling energy can easily spread throughout the house.

    When trying to assess the feng shui of a specific staircase, look at these factors:

    The Location of the Staircase

    The worst feng shui locations of a staircase inside a home are:

    • a staircase facing the front door
    • a staircase in the center of the home

    The Design and Style of the Staircase

    The worst feng shui designs of a staircase are:

    • a design with open space between the steps
    • a staircase with metal railing and handrails in a wood feng shui element area

    Generally, it is best to avoid the spiral-shaped (or corkscrew) design of a staircase in the center of the house, especially if the staircase is made mostly of metal.

    Because the feng shui energy of a staircase is an unsettled, up-and-down energy, it is good to focus on creating a more balanced, grounded energy by applying easy feng shui decorating tips.

    For example, you can:

    • Use surrounding walls to display art and photos in visually strong frames. Choose colors and materials according to the feng shui element needed in the specific bagua area.
    • Install lighting with a strong presence, this can help ground and calm the energy. You can choose one big chandelier or several visually attractive wall sconces; decide which design suits your home style the best.
    • Consider adding beautiful architectural features, be it wainscoting or moldings, they will add character and presence to your staircase area.
    • Maximize your landing area space by adding beautiful art or healthy, lush plants in stylish pots. If the bagua area where your staircase is located can benefit from the water feng shui element, sure consider adding a framed mirror or a small fountain.

    With just a bit of planning and effort, you can truly transform the energy of your staircase and stop worrying about its bad feng shui.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Here is a perfect trick to draw a 3D sphere so fast in Solidworks.

    Please click it worked below.. 😉

    Step 1: Open

    Open a part file in Solidworks and Open a sketch wherever you want (Top plane, Right Plane, Front plane or any other plane that is made by you)

    -“Ön Düzlem” means Front Plane in Turkish. My operating system’s default language is Turkish, i can not change my SW fully in English-

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Step 2: Draw

    Draw a circle. (With two point circle) That will help you to attach your drawings on some points like attaching the center point of circle to the origin.)

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Step 3: Use smart dimension

    Use smart dimension to size your circle. That will make your drawing fully defined. (blue lines will turn to black.)

    Select centerline (contionous line will work too but centerline is better) and draw a vertical line on the horizontal center of the circle.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Step 4: Select Trim

    Select trim tool and click on “trim to closest”. Than click on the left or right side of the circle (directly to the line) to get a half circle. Click on the green button on the top right to confirm trimming.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Step 5: Sketch confirmation

    Now you have a half circle. Click on the sketch confirmation button on the top right.

    Think It Through

    It’s a beautiful summer day. You grab your swimsuit and a towel, and you’re ready for the pool! It’s easy to make this decision because all the circumstances are ideal for a dip.

    But let’s say, the temperature is really hot. In this instance, you might grab a water bottle and lots of sunscreen, then head to the pool.

    Or let’s say, it’s drizzling. You may check to make sure there is no thunder or lightning before you’d venture outside for a swim. In all these situations, you are using your brain to assess the status of multiple conditions before proceeding with your plan. These same critical thinking skills are necessary when preparing to give a client a massage!

    Massage therapists must employ clinical reasoning, or the process of evaluating a patient’s health history, current symptoms and previous response to intervention in order to formulate a massage treatment plan that will be beneficial. This clinical reasoning must happen before every massage! Why? Because there is no perfect client; no formula. Every patient will have various needs, some more than others.

    Massage may still be possible for a patient with multiple contraindications; however, the massage therapist must utilize clinical reasoning!

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Types of Contraindications

    Let’s quickly review common contraindications to massage. These contraindications are divided into four sub-types:

    Absolute Contraindication

    An absolute contraindication is a situation in which a massage cannot safely be performed. Absolute contraindications include:

    • Symptoms of acute illness, such as fever, vomiting, diarrhea
    • Blood thinning, due to a medical condition or medications
    • Blood clotting, due to a medical condition or procedures
    • Open wounds or new surgical sites
    • Contagious illness, such as the flu or skin infections
    • Organ failure

    Relative Contraindication

    A relative contraindication is a situation in which a massage should be given with caution. Relative contraindications include:

    • Chronic illness, such as diabetes or cancer
    • Pregnancy

    Generalized Contraindication

    A generalized contraindication is a contraindication that impacts the entire body. For example, a client that has severe sunburn on his face, trunk, arms and legs.

    If a contraindication manifests over the whole person, then it is considered generalized.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Localized Contraindication

    A localized contraindication impacts a specific site on the body. For example, a client has severe sunburn only on the tops of his feet.

    Putting It All Together

    Looking at each of these contraindications separately may seem straightforward. However, the beauty, and challenge of real people is their complexity. Rarely will a client present with one very clear contraindication, but rather a combination of limiting factors, which is when clinical reasoning becomes even more important.

    Say Charlie has prostate cancer and congestive heart failure. He has been undergoing chemotherapy and is responding well to it. However, Charlie has many venous stasis ulcers (open wounds) on his lower legs and feet. What should you do?

    You may be tempted to tell him, ”Well, you can’t have a massage.” But Charlie can have a massage with modifications! Charlie has cancer, a relative contraindication, which will require changes. By asking Charlie which symptoms he is currently having, such as fatigue or nausea, you will be better equipped to make the appropriate adjustments to the generalized massage.

    Secondly, Charlie has open wounds on his lower legs, which represent an absolute localized contraindication. What does this mean? It means under no circumstances would you massage Charlie’s lower legs.

    Importance of Intake and Modifications

    More information actually makes the clinical reasoning process easier. Interviewing a patient thoroughly about current symptoms, treatments and side-effects provides the foundational information for tailoring the massage to the patient’s needs.

    Specifically, seek to understand:

    1. What about the patient’s condition contraindicates massage therapy?
    2. What about the massage therapy needs to be modified?

    Once this is understood, then a massage therapist’s can make changes to:

    • speed and rhythm
    • duration
    • pressure
    • joint movement and body positioning
    • lubricant and draping

    Consulting and Additional Training

    If a patient has one or more contraindications, then pursuing a medical consultation is advisable. Before discussing the case with the healthcare provider, be sure to have thought out the massage modifications you’d like to implement and be prepared to explain why these would be advisable. This preparation will help make the decision-making process with the provider more productive.

    Lastly, specialized training may make massage possible despite certain contraindications. For example, massage therapists may obtain additional training to perform scar-reduction massages or massages during pregnancy.

    Lesson Summary

    Massage can be a means of healing; however, a massage therapist must use clinical reasoning when a client with one or more contraindications presents for treatment. Clinical reasoning involves evaluating a patient’s health history, current symptoms and previous response to massage in order to make a massage treatment plan that will be helpful and safe for the patient.

    Type of Contraindication Definition Examples
    absolute contraindication massage prohibited acute illness, blood thinning conditions, blood clotting conditions, open wounds, contagious illnesses, organ failure
    relative contraindication modified massage may be given with caution cancer, pregnancy
    generalized contraindication contraindication that affects the entire body compromised immune system, fibromyalgia
    localized contraindication contraindication that affects a specific body part surgical site, bruise, joint injury, varicose veins

    In response to the type and number of contraindications, the massage therapist may alter:

    • speed and rhythm
    • duration
    • pressure
    • joint movement and body positioning
    • lubricant and draping

    Medical consultation or additional training may be necessary before a massage therapist has all the information needed to provide a safe, beneficial massage for a patient with multiple health conditions.

    Making a custom brush for Illustrator is much easier than you may have expected. This tutorial was requested by many of my readers after I posted this free set of 35 Abstract Illustrator Brushes. The possibilities are endless as far as Illustrator brush-making goes, but I wanted to get you started in the right direction and let you take it from there. (The purpose is to tease you, so you want to try it on your own!)

    How to Create a Spiral with Heart Center of Sinewave Spheres

    It would actually be pretty hard to make this tutorial any more detailed because making custom Illustrator brushes honestly couldn’t be easier. However, there are a couple of things you need to know first. There is no doubt that brushes are really a time-saver for a professional and really convenient for the newbie. If you can learn and practice the craft of creating custom brushes, then you are ahead of most of your competitors. This is the tutorial around which other tutorials are based.

    There are 4 types of brushes you can create in Illustrator: Calligraphic, Art, Scatter, and Pattern. Today we’ll go over creating an Art Brush. While we’re exploring how to make an art brush, you can experiment with other brush types in the same fashion; the only differences are settings, and how the brushes act when applied. In the world of Photoshop, there are endless possibilities to perform a certain task and you must be aware of all the available tools and settings that can help you achieved desired results. Designing tools from scratch may be a lengthy and troublesome process for all the designers especially the beginners. But, if you are looking to go completely self-made and creative, then you must go through these tutorials. It is just like programming but in a manual way. There are thousands of custom illustrator brushes available to be downloaded that have been designed with great precision.

    Editor’s note: If you’re looking to find out more on creating custom Illustrator brushes, I’ve got a handy tutorial on the ‘colorization method.’

    Make a Custom Illustrator Art Brush:

    First, open a new Illustrator document and make any shape your heart desires. You can literally make ANY shape into a brush, even a square if you feel like it. Here’s what I made. A couple of bars and some blocks scattered about. No need to worry about shapes at this point, because once you try this a few times, you’ll get an idea of how the shapes affect your brush.

    Illustrator brushes are different from watercolor brushes and these can be used to construct different tiny geometrical shapes, drawings or other artwork from scratch. Illustrator brushes can be used to illustrate almost anything in different artworks such as to illustrate a text or drawing in poster designs.

    Select all the shapes you want to be a brush. Then, in your Brushes palette, click on the little arrow in the upper left, and select “New Brush.”

    How to Create a Spiral with Heart Center of Sinewave Spheres

    You will get the option to choose 1 of 4 brush types. Choose “Art Brush” and click OK.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    It is also very important to decide the direction of a brush in which it is projecting so as to achieve the perfect stroke that you want to. You can create several custom brushes so that each brush help you in your work. Professional designers use several brushes to create a perfect masterpiece for their clients. You can flip the brush horizontally or vertically so as to flip the stroke that it produces.

    Now you should be in the Brush Options. IMPORTANT: Make sure you select “Tints” as the Colorization Method. This allows you to change the color of the brush like a stroke color. If you don’t select Tints, your brush will always be the color it is when you create it. There are lots of other settings you can play with here, including the direction of the brush stroke. Choose your settings and click OK.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    You should now see your new Custom Brush in the Brushes palette.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Now create a shape to test your brush. I used a circle, like below:

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Now make sure you have the stroke selected in the tools palette, and click on your Custom Brush in the Brushes palette to apply it to the circle to see what you get:

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Custom Brushes are an easy way to get shapes that would have otherwise taken hours to draw by hand. Now that you have your brush, you can start applying it whenever you want. Just adjust the stroke size to get the effect/shapes you want. In the image below, all I did was use the same brush I just created, duplicated it, overlapped it, and adjusted scale, colors, and stroke sizes.

    You can make multiple brushes in order to get way more complex, and the more you try it, the better you get. Seriously, this took about a minute with one brush (made from simple rectangles!). Imagine what you can do if you spend some time experimenting?

    Creating circular and spiral arrays typically involves some combination of moving, scaling, and rotating copies along one or two axes and around a common center. The effects can vary from the uniform radial arrangement of bolts on a wheel hub to the complex geometry of a spiral staircase. You can model many circular patterns with these techniques.

    For an explanation of interface terms used here, see Array. For the basic steps in making an array, see this movie.

    Using a Common Center

    Both circular and spiral arrays require a common center for the arrayed objects. This can be the world center, the center of a custom grid object, or the center of the object group itself. You can also move the pivot point of an individual object and use that as the common center.

    Circular Arrays

    How to Create a Spiral with Heart Center of Sinewave Spheres

    A circular array

    Circular arrays are similar to linear arrays, but based on rotation around a common center rather than movement along an axis. The following procedure makes a circle of objects on the XY plane of the home grid with the Z axis as the center.

    Play this to see an example of creating a circular array centered on the World origin:

    To create a circular array:

    1. On the main toolbar, choose a transform center to become the center of the array. In this case, choose Use Transform Coordinate Center so the center of the grid becomes the array center.
    2. Select an object and position it at some distance from the center of the grid.

    This distance is the radius of the finished circle.

    On the Extras toolbar, choose (Array) from the Array flyout, or on the Tools menu, choose Array.

    3ds Max opens the Array dialog.

    This is the total rotation for the array, a complete circle. To create a partial circle, enter a smaller value.

    Choose 1D and enter a Count value (this can be any number) and click OK.

    3ds Max arrays that number of clones within the total rotational angle you specify.

    Spiral Arrays

    How to Create a Spiral with Heart Center of Sinewave Spheres

    The simplest spiral arrays are rotated circular arrays with a movement along the central axis. The same circle is formed, but now the circle rises upward.

    If Z is the central axis, enter a value for Incremental Move Z. Each clone is then moved upward this amount as the circle is formed.

    Rotation in Spiral Arrays

    In spiral arrays, the direction of rotation determines the direction of the spiral: which way it winds up or down.

    Enter a positive rotation for a counterclockwise spiral.

    Enter a negative rotation for a clockwise spiral.

    Reorienting an Array

    By default, each object, when copied into the array, rotates around its own center to follow the main rotation around the common center. This is controlled by the Re-Orient option.

    To cause objects to maintain their original orientation while being rotated, turn off Re-Orient. In effect, objects remain “facing the same direction” as the original object.

    Because bakery cakes are often incredibly moist and fluffy with a tender crumb, many home bakers find themselves on a quest to create a bakery-style cake in their own kitchens. An ideal bakery cake is usually decorated with bakery-style frosting, which holds up well for piping intricate designs on the cake. With this recipe for classic yellow cake and vanilla buttercream frosting, paired with a couple of decorating ideas, you can make a cake that’s worthy of being displayed in any bakery window.

    Making the Yellow Cake Batter

    Preheat your oven to 350 degrees Fahrenheit. Apply baking spray to your pans. Cut out 8-inch circles from your parchment paper and fit the bottom of each pan with a piece of parchment paper; set aside.

    Beat 1 cup of unsalted butter with the granulated white sugar in the bowl of a stand mixer, or in a large bowl with a hand-held mixer, until the two are creamed together and fluffy, about 5 minutes.

    Add the eggs, 1 at a time, beating well after each addition. Then, add the self-rising flour and cup of whole milk into the batter in 3 alternating batches, beginning and ending with the flour.

    Add in 1 teaspoon of vanilla extract and the imitation butter flavoring. Give the batter a quick mix to combine. Then, evenly divide the batter among the 3 prepared cake pans.

    Hold the pans about 3 inches above your counter before dropping each pan onto the counter several times. This will release any air bubbles in the batter. Bake the cakes for 25 to 30 minutes, or until the cakes immediately spring back after being gently touched.

    Allow the cakes to slightly cool in their pans for approximately 10 minutes. Use a knife to run along the edges of the pan before flipping each cake layer out onto a sheet of plastic wrap. Wrap each layer tightly in the plastic, and let the cake layers cool completely before frosting.

    Create the Vanilla Buttercream Frosting

    To create the frosting, beat the remaining cup of unsalted butter in the bowl of a stand mixer with the paddle attachment. Alternatively, you can beat the butter in a large bowl with a hand-held mixer. Beat until smooth and creamy.

    Add the powdered sugar and beat to combine. Add the remaining teaspoon of vanilla extract and mix.

    Frost the Cake

    Once the cake layers have completely cooled, unwrap the plastic wrap from each. Place one cake layer, flat-side down, on the center of the cake board. If the tops of the cake layers are slightly dome-shaped, use a serrated knife to cut off a sliver of cake so that they’re all completely level.

    Add a few dollops of the buttercream frosting onto the surface of the first cake layer. Use your offset spatula to gently smooth out an even layer of frosting all the way to the edges of the cake. Add a second cake layer and, again, add a few more dollops of frosting on top and smooth out to the very edges of the cake. Finally, place the third layer of cake on top.

    Carefully transfer the cake, with the cake board upon which it’s sitting, to a turntable. Use your offset spatula to apply frosting to the sides and top of the cake, turning the cake on the turntable as you go. To create a smooth finish when frosting the cake, periodically dip your offset spatula in some lukewarm water before shaking off the water from the spatula and running it against the frosting as you proceed.

    Decorate the Cake

    To add some flair to your cake, fill a pastry bag fitted with a star tip with some of the leftover buttercream frosting. Pipe stars on top of the cake, all along the rim.

    Pour out some colorful sprinkle dots into the palm of one hand, and use your other hand to grab a pinch of sprinkles at a time to drop directly onto the piped stars.

    Storing and Serving the Cake

    If you don’t use any milk in the frosting, you can safely store the cake at room temperature for up to 3 days. Otherwise, refrigerate the cake until ready to use. Then, let it sit out on the counter for 15 to 20 minutes prior to serving.

    Organized chaos comes with a caveat: The chaos is only organized from the perspective of the person who created it in the first place. To everyone else, it’s just a mess. A new kinetic sculpture called Breaking Wave explores the idea of how a change in perspective can bring clarity to chaos—in this case the chaos being 804 wooden balls that are suspended from the ceiling in the lobby of Biogen-Idec, a biotech company in Cambridge, Massachusetts.

    Biogen-Idec commissioned Hypersonic, a Brooklyn creative engineering studio, and Plebian Design to create an anchoring sculpture for its office. From most perspectives, Breaking Wave is simply a mess of dangling spheres. But every 80 seconds, if you happen to be in the exact right position, you’ll see the balls align into a perfectly focused image of a Fibonacci spiral and a circular labyrinth, like a 3-D version of Magic Eye.

    The concept is a nod to Biogen-Idec’s work, which harnesses the power of data to create new medicines for people with neurodegenerative diseases and autoimmune disorders. “What they have is a massive amount of data that they have to look at in the right way in order to make something from it,” explains Hypersonic’s Bill Washabaugh. Looking at the data sets as a series of raw numbers gives little clue to their significance, but given the right framework, scientists are able to create life-changing drugs.

    There are two spots in the Biogen-Idec office from which the sculpture appears as a perfect spiral (One is found in the main lobby, just past security, and the other is from outside the building looking in through the front windows). Ensuring the the sculpture held two simultaneous images was an engineering feat. “The technical challenge here is that I have two images that I want to see at the same time,” says Jeff Lieberman of Plebian Design in the video (made by Alberta Chu of ASKlabs). “This one cloud has to accomplish both of those things.”

    Solving that problem took some old-school math work. Thankfully, both designers are self-proclaimed math and science geeks who happen to have an artistic bent. Before founding Hypersonic, Washabaugh was an aerospace engineer for Boeing, and before founding Plebian Design Lieberman was a PhD candidate at MIT. The structure they came up with for Biogen-Idec tapped all of this expertise. It’s a complex mechanical system of more than 1,000 moving parts. One motor at the top of the piece drives all the movement, with thirty-six roller tracks move across a rotating stainless steel cam. Each of those tracks control a stainless steel cable that winds around dozens of drums of varying diameters. It’s those drums that control the movement of the 804 spheres. A large drum diameter lifts a ball high, while the movement of a small drum is more subtle—combined they make the precise animation possible.

    Washabaugh, Lieberman and their teams mapped out the movements in software, plotting the correct coordinates so that the spheres would move in an exacting motion without looking jerky and stiff. Watching Breaking Wave in action is like watching hundreds of circular puppets doing a highly-choreographed dance. The balls undulate like a wave before pulling up into a perfect six-and-a-half foot in diameter sphere. The piece is an ode to not just art, but to the science that makes it possible. “It’s really exciting to find ways to combine art and science together,” says Washabaugh. “The sculptures and pieces we create not only look interesting and cool, but they challenge the way people see the world and think about art.”

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Microsoft Word makes it easy to add geometric shapes (and a whole lot more) to your document. You can also add text into these shapes, which is handy when you’re creating flowcharts, network diagrams, mind maps, and so on. This being Word, there are plenty of options for doing this, so let’s take a look.

    First, you’ll need to insert a shape by going to Insert > Shapes. We’re going to use a nice rounded rectangle, which by default will be filled in with blue.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    Right-click anywhere in your shape and click the “Add Text” command.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    This places an insertion point in the shape where you can type your text. Once you’ve added whatever you want to write, the “Format” tab has tools you can use to give your text a little pop with things like text styles and shading.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    You can also select the text and use the standard Font, Paragraph and Styles tools on the Home tab to format your text, just as if it were a normal part of the document. When you right click your text, you’ll find the usual quick options as well.

    Add a Text Box

    If you’d like a little more control over the placement and boundaries of your text, you can add a text box inside your shape instead. When you insert a new image or select an existing image, Word automatically switches you to the “Format” tab. You’ll see two ways here to insert a text box, both of which add a text box in the same way.

    Select one of the options and move the cursor over your image. A yellow “+” mark will replace your pointer. Hold down the left mouse button and drag the “+” mark to create a text box. When the box looks about right, release the left click (don’t worry if the text box isn’t exactly the right size or location, you can change it afterward), and your text box will be created.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    You can use the handles (the little squares) around the text box to resize it or select the whole text box to move it around within your shape. Add your text and format it in whatever way you want.

    There are also text boxes with preset formatting that you can add by selecting your shape and then clicking Insert > Text Box. We’ve only scratched the surface of what you can do with text boxes here, so if you want to know more check out our guide to text boxes and all the things you can do with them.

    Topiary is the art of sculpting greenery into fun and creative shapes. These elaborate works of art can usually be found in stylish and well-maintained gardens, but they don’t have to be associated with wealthy households and private gardeners. Trimming a bush into an interesting shape is not as complicated as it may seem; even the novice can create a magical piece to delight the beholder.

    Best Shrubs for Topiary

    Boxwood, ivy, privet, and yew are the most popular shrubs to shape into topiary forms. These evergreens have small leaves, and they grow slowly and densely which makes them a perfect blank canvas for trimming into anything. Not to mention, they don’t require as much maintenance to keep their shape as other types.

    Step 1 – Choose a Shape

    Early summer is the best time to start your topiary project. Think about the figure you want and assess the existing shape of your shrub. Sometimes, your plant will already resemble a certain pattern and this can give you an idea of how to develop it. Focus on the fundamental geometrical shapes needed for things like a spiral, a cube, a bird, or animal. A basic topiary such as a cube, cone, or pyramid is simple enough for the novice gardener but it will still give a sense of accomplishment.

    More elaborate figures such as a peacock, swan, bear, guitar, or woman are not necessarily complex to create, but they take more time and patience. Therefore, carefully consider what you may want and how much time you intend to invest in the project.

    Step 2 – Use Wire Frame

    If you are a complete beginner, wire frames in different shapes are a practical tool to get you started. Alternatively, you can make your own template from a wire frame. Pick one and place it on the bush. Then, prune the shrub branches where they are sticking out. Your shears have to be clean and sharp, as pruning with blunt tools only harms the stems. With regular trimming, the shrubs will be “trained” to grow around the frame, but you need to be patient as the process takes time.

    Step 3 – Trim Without a Wire Frame

    When trimming without a wire frame the process is somewhat different. First, you will want to slowly and carefully form the shrub into a basic geometrical shape. For example, for a cat, trim the bush into an oval shape. Then, place some sticks to act as reference points where you want the head or the tail. Tie the sticks with a string to the shrub if necessary. As the shrub grows, trim the selected stems into details such as head, tail, paws, etc. This process can take several years but with persistence, your topiary will become a focal point in the yard.

    Step 4 – Care for Your New Bush

    Your shrubs will still need regular watering, especially in hot months, so that they retain their form and look healthy and green. Also, keep them free of insects and pests.

    Depending on the type of shrub you have used, the frequency of necessary trimming varies. Some types of plants grow fast while others take several years to form into a shape.

    Topiaries are an exquisite and sophisticated addition to your landscaping and can set a magical atmosphere. They are not so complex to make, but definitely require a significant amount of patience.

    The older Plotz version can be found here

    Welcome to the new Plotz, written using HTML5 features and Javascript. It has been designed to work with touch screens and mobile devices supporting orientation change. I hope you enjoy using it trouble free. However with my limited time its hard to account for all possibilities. Its new and there may well be bugs. Please read the notes below if you’re experiencing any problems.

    You can find the old Plotz modeller here. Please complete any models you started with the older Plotz using that version as the newer Plotz does not create the exact same models block for block.

    Ensure your web browser is up to date. I suggest using Chrome, Firefox or Safari web browsers.

    A failure to render, especially on low end or mobile devices could be lack of memory. In this case I suggest you close any other windows or apps, reload the page, and if the model includes the ‘precision’ setting, use a low value. Larger models use more memory.

    Working on the iPad or tablet device? Try maximising the time your device takes before powering off and reduce screen brightness to save battery life.

    The current version of Plotz does not print. If you require a printout of schematics use the old Plotz.

    Plotz works on iPhone only as its written on HTML5 and Javascript standards. Its not very useful on such a small screen however.

    How to Create a Spiral with Heart Center of Sinewave Spheres

    What is viral fundraising? It happens when a fundraiser spreads rapidly throughout the internet. And you benefit because it drives an unparalleled amount of traffic to your fundraiser.

    Viral content leaves a lasting impression. The key is that it evokes an emotion. Crowdfund\ing is often an emotional experience that can be both heartbreaking and heartwarming. You can use those emotions as a part of your fundraising strategy.

    Although there isn’t one blueprint to make your fundraising fundraiser go viral, there are a few ways to ensure that it has the potential.

    Broken down to its bare essentials, a viral fundraiser must have :

    1. A relatable story
    2. Captivating content
    3. Channels to share

    Often fundraising fundraisers go viral as a result of a powerful piece of content that is shared with it. Outlined below are tips for creating your fundraiser, matching it with amazing content, and finding the right channels to share it on.

    1. Building your fundraiser’s foundation

    Determine your audience

    First, decide who your target audience is. Choose one that is most likely to resonate with your story. Then, do some research on their likes, dislikes, and values. Once you understand who they are, you can design a powerful message that moves them to engage with your cause.

    Keep your title simple

    Your title should be a clear introduction to what your fundraiser is about. Include the beneficiary’s name then add a few keywords that help summarize why you are raising funds. A great strategy is to come up with an unforgettable hashtag to add to the end of your title. Here are our tips on creating a fundraiser hashtag .

    Write your fundraiser description

    There are two goals of viral fundraising. First, you want people to share your fundraiser. Second, you want to invite people to click your fundraiser link and donate. Once someone lands on your fundraiser, they will read your fundraiser description to gather more context. This is where you should break down why you raising money, who the money is for, and how the money will be used.

    2. Match your fundraiser with amazing content

    Make your message shareable

    The next step is going to be sharing a post on social media that links to your fundraiser. The goal is for that post to go viral. Viral content must be easy for readers to digest while piquing their interest. People will only share your post if they deem it worthy. So frame your story in such a way that people will want to be a part of the solution.

    For example: Before Matt’s fundraiser Chauncy’s Chance went viral, it was his original Facebook post that captured attention. He shared his story of meeting Chauncy in an honest, emotional way. His post got shared so much that, once he started his fundraiser, he already had an audience ready to donate.

    Create a viral video challenge

    People want to be giving. So give them the opportunity to practice their altruism in a new way like a video challenge.

    For example: In honor of his late friend Garmt, Andrew started the Hot Pepper Challenge for ALS . Taking a cue from the famous ice bucket challenge, Andrew asked his friends and family to endure a pepper as hot as they could handle; the hotter the pepper, the less money they’re asked to donate. No matter what, each nominee must nominate three others to take the challenge. Thanks to a viral video that got more 1.4 million views, Andrew raised more than $25,000 for this cause close to his heart.

    Trigger shares with high-quality photos

    If you don’t have the time or the resources to create a video, high-quality photos that evoke powerful emotional responses can be used to help your fundraiser go viral. Get creative and brainstorm photo ideas that will whoa potential donors. An intriguing photo will force people to stop scrolling through their feed to find out more about your fundraiser.

    For example: Joel started his fundraiser Relief for Fidencio the paleta man when he saw an elderly man in his neighborhood, still hard at work selling popsicles (paletas). His touching photo of Fidencio played a critical part in fueling the fire of this viral fundraiser.

    Be clear in your call to action

    You should always include a call to action at the end of your post. Ask for a donation first, but make your ask manageable. Often asking for a smaller amount like $10 to $25 will get you more donations than a larger ask. And if someone can’t give, then encourage them to help by sharing your fundraiser with their online network.

    For example: When Donald wanted to help a fast food employee get to school to become a CNA, he did a little math in his fundraiser, Send a Random Girl 2 Nursing School . He figured he could reach his goal of $1,500 if 300 of his Facebook friends gave $5 each—and he ended up raising more than $15,000.

    3. Strategizing your sharing

    Make connections

    Leverage social media to build your fundraising community. Reach out to people with large spheres of influence. Then ask them if they would be interested in supporting your efforts. Before you share your post to social media, send a message to your influencers reminding them to share your post as soon as you do.

    Share on multiple platforms

    Facebook is a great tool for sharing, but don’t underestimate the power of other platforms like Twitter or Instagram. Plan on posting on several social media platforms to maximize your chances of going viral. And remember to always include a link to your fundraiser in your post.

    Know when to share

    The day and time that you share have a lot to do with whether or not your post will be seen, liked, and shared. Many quality posts fall beneath the cracks because they are shared at the wrong times. Use this social media research to guide your posting.

    The best time to post on Facebook :

    • From 12 to 1 p.m. on Saturday and Sunday
    • From 1 to 4 p.m. on Thursday and Friday
    • At 3 p.m. on Wednesdays

    The best time to post on Twitter :

    • 12 to 3 p.m. and 5 p.m. on Monday Through Fridays
    • Noon and from 5 to 6 p.m. on Wednesdays

    The best time to post on Instagram :

    • Anytime besides 3 to 4 p.m. from Monday through Thursdays
    • Videos get more engagement after 9 p.m.

    Abstract

    Considering a fatal case of an aged individual, who died due to falling down stairs, the cause of the fatal fall was investigated through experiments. A witness, who was with the victim, when the fatal accident occurred, stated that the aged individual had miss-footed, lost balance at the top of the stairs, and fell accidently from an upper floor to a lower floor. It was very questionable whether or not this witness’s statements were true. The true cause of the fatal fall was unclear, because of the witness’s inconsistent statements, which showed discrepancies between the initial and later statements. The cause of a fatal fall can be presumed from external and internal damages to the body and other circumstantial evidences. But it was difficult to prove the true cause of a fatal fall only from the results of the autopsy and investigation of circumstantial evidences. The author was officially requested to conduct experiments to elucidate possible falling patterns. Judging from the experimental results, deep questions about the witness’s statements arose. These experimental methods and analyses in this paper could be applied to elucidate possible falling patterns of fatal falls from stairs where the fatal causes are controversial.

    Introduction

    According to the mortality statistics classified by the International Classification of Diseases recommended by the WHO-World Health Organization, 1,917 deaths due to falls on/from stairs and steps in the United States in 2007 1 ) , 693 deaths in England and Wales in 2011 2 ) , and 679 deaths in Japan in 2012 3 ) . Many researchers have undertaken demographic or epidemiological surveys for stair related injuries 4 , 5 , 6 , 7 ) . As far as the author surveyed past literatures, an experimental article for a fatal fall based on the autopsy results and detailed configurations of stairs, where a fatal fall occurred, was not found in past research papers. Most fatal falls from stairs are caused by serious head injuries 5 , 6 , 8 ) . Whenever a fatal stair-accident occurs, the actual duration time until receiving the first impact by falling down the stairs is within a second, according to the author’s experiments 9 , 10 ) . Because of the instantaneous occurrence of a stair fall, it is very difficult to find a witness who sees the entire falling patterns down stairs.

    In the case of no witnesses, the cause of a fatal fall can be sometimes determined from external injuries on the corpse and circumstantial evidence. Computer simulation can be used to determine the possible falling patterns, nevertheless, these simulated results are likely to be largely influenced by initial input parameters, and are not always reliable to identify the specific decisive causes of actual fatal falls. Taking one fatal case of an aged individual, who died of severe head injuries, due to a fall down the stairs at a residential home, the cause of that fatal fall was investigated. Only one witness was with the victim when the fatal accident occurred. It was questionable whether or not the witness’s comments were true. The fatal fall was examined using a dummy and experimental stairs with the same configurations, such as the dimensions of the tread rise etc. From the analyses of the experimental falls by a dummy from stairs, serious questions about the witness’s statements arose.

    Conditions of the Fatal Fall

    Statements by people specifically involved in this investigation

    It was reported that one aged individual fell from the top of the stairs at victim’s home. According to the initial on-site statements of the witness, the aged victim had accidentally miss-footed, lost balance at the top of the stairs, and fell from an upper to a lower floor. But strong doubts arose from statements by the rescue crew members. They found broken debris scattered around the top of the stairs just after arrival at the victim’s home. When they questioned as to what happened, the witness confessed to have had a quarrel with the victim at the upper floor near the entrance to the stairs. The witness implied that witness slightly pushed the aged victim just before the occurrence of fall-incident in witness’s first comments. Judging from the suspicious circumstantial appearances, the rescue crew members speculated that some sort of skirmish had occurred and about the possibilities of violent action such as shoving the victim near the upper stairs might have occurred. They reported this information to the regional police office. Several policemen soon came and questioned the witness on-site. They suspected the witness’s explanation because of inconsistent statements and indications that the aged victim was shoved at the top of stairs. After retaining attorneys, the suspect stated that the victim fell down from the top of the stairs accidentally and completely denied the initial statements that the witness gave external forces to the aged victim, and exercised one’s own constitutional right to remain silent during the public prosecutors’ interrogations. The public prosecutors were undermined as to the true cause of the fatal fall.

    Physical conditions

    Based on a detailed search warrant of the actual stairs, an inspection was conducted by public inspectors, police officers and the author as shown in Fig. 1 . The wooden stairs were 177 cm long and 264 cm high. The stairs with width of 90 cm consisted of 12 steps with a tread of 16.6 cm and a rise of 22.0 cm except for the top step, which had a tread of 23.0 cm and a rise of 25.0 cm with non-slip vinyl edge of the step. The incline of stairs was 53 degrees except for the top part of the stairs which was 47 degrees. A handrail was installed at one side wall of stairs with the height of around 70 cm from the step edge. The heights from the landing of the 1st floor to the overhang above stairs was 207 cm.

    I’m trying to make some shapes with Java. I created two rectangles with two different colors but I want to create a star shape and I can’t find useful source to help me doing this.

    Here is my code:

    You could try using a polygon and some basic math:

    You can also use existing classes e.g. http://java-sl.com/shapes.html for regular polygons and stars.

    The Polygon class can be considered as a legacy class that has been there since Java 1.0, but should hardly be used any more in new code. The odd way of specifying the x/y coordinates in separate arrays, and, more importantly, the fact that it only supports int[] arrays limits its application areas. Although it implements the Shape interface, there are more modern implementations of this interface that can be used to represent polygons. In most cases, describing the polygon as a Path2D is easier and more flexible. One can create a Path2D p = new Path2D.Double(); and then do a sequence of moveTo and lineTo calls to geneate the desired shape.

    The following program shows how the Path2D class may be used to generate star shapes. The most important method is the createStar method. It is very generic. It receives

    • the center coordinates for the star
    • the inner and outer radius of the star
    • the number of rays that the star should have
    • the angle where the first ray should be (i.e. the rotation angle of the star)

    If desired, a simpler method may be wrapped around this one – as with the createDefaultStar example in the code below.

    The program shows different stars, painted as lines and filled with different colors and radial gradient paints, as examples:
