Large predators are uncommon in tropical rainforests because large prey species are also rare. The carnivores that do exist have adapted to be able to hunt above ground in the forest canopy as well as on the ground; they have also adapted to eat smaller prey. Many omnivorous animals--animals that ea
Insulators, also called dielectrics, are non-metallic solid materials that resist the flow of electrons. Insulators offer a protective barrier when placed over electrically charged materials that could potentially shock, such as electrical wires. Factors such as an insulator's material, temperature
Decorate your holly tree gift with red bulbs; it won't be blooming for a few years.christmas holly image by Julianna Olah from Fotolia.comHolly trees are a hardy and festive tree during the Christmas holiday. This evergreen produces red berries if you have several growing together to...
Containers are used not only to hold plants but also to add aesthetic value to a building's interior or exterior. One type of container that is utilized for its appeal and practicality is the terra cotta pot. While these pots can offer unique ornamentation, their porous nature increases the amount o
An inert gas that makes up about one part in 65,000 of air by volume, neon's density changes predictably with temperature and pressure. Familiar to most people for its use in electric signs, neon is relatively light. And because it's non-flammable, it's safe to work with.
An electrical device exposed to the wrong type of electrical energy can become damaged. All devices with a detachable power cable require either DC or AC power, and are labeled as such. If the original power cable is lost, and an electrical device requires DC power, you can construct a power adapter
Installing molding requires many different skills including how to cut mitered joints for corners that are at 90-degree angles. On older homes, where the corners may not be at precise 90-degree angles, an effective alternative is the coped joint. The coped joint requires that the molding on one wall
Most atomic clocks will adjust their time after a time change automatically. The clock might not adjust at the time you go to bed, but will the next time the clock receives the radio signal to calibrate time. If your clock has the daylight savings time feature turned off, then you can manually enter
A cylinder is a geometrical shape that has circles as the top and bottom bases. The cylinder length (height) corresponds to the top to bottom distance. The volume of a cylinder is obtained by multiplying the length of the cylinder by the square of the radius of the circle base, multiplied by pi, the
Creating a family tree is a project all family members will enjoy. By tracing their lineage, family members can document ancestors as well as inscribe special dates such as birthdays and anniversaries. Choosing a diagram-like family tree template take very little time to design, but can be impersona

One method for measuring the rotation of a motor involves coupling a mechanism to the motor shaft that provides leads to a tachometer circuit. This results in mechanical loss that also prevents the motor from turning at it maximum speed. Another method can be done without making contact with the m
From delicate curls of gold to the almost unearthly shimmer of silver, embossing is usually used on cards and other delicate decorations. However, it can also be utilized to decorate wooden alphabet blocks, creating the perfect centerpiece or decoration in a child's room or even a library. Each bloc
Converting the Tyler mesh screen size from microns to inches is sometimes required when trying to determine whether granular materials like peanuts, fertilizer, grain, and rice contain too many bad pieces. The process is developed by placing a large quantity of a granular material on a Tyler mesh to
Tempered glass is used for doors, windows, automotive glass and other areas where glass shards would be dangerous. When impacted, tempered glass will stay in the frame, increasing the safety.
