HP 8590A Specifications
The HP 8590A, called the HP/Agilent 8590A after Agilent spun off Hewlett Packard, is a portable RF spectrum analyzer. Spectrum analyzers are able to read the frequency and amplitude of an electrical or acoustical waveform and perform some basic computations on those readings.PhysicalThe...
How to Modify RC Engines
Modifying an RC engine can gain you greater engine efficiency, increasing the air/fuel mixture flow through the engine without requiring major modifications that could otherwise throw off the balanced working of the engine. This can be accomplished by slightly modifying the piston sleeve of your unm
What Is Crossing Over in Genetics?
A gene is defined as a unit of heredity that is passed along from one generation to the next, according to MedicineNet.com. Genes comprised short sequences of deoxyribonucleic acid, or DNA, and are arranged along chromosomes. Chromosomes are simply long sequences of DNA made up of many genes. In the
Why Does Food Preservation Occur During Canning?
PreservationCanning preserves food in two ways. During the canning process, heat kills off microorganisms in the food. The heat also drives air out of the jar, expelling any microorganisms in the air and creating a vacuum seal that keeps germs out. Without exposure to air, the food inside...
How to Be Prepared For the Hurricane Season
When it is hurricane season, the best thing that you can do is be prepared. Follow these steps to be prepared for the hurricane season.
How to Replace Cuckoo Clock Crest
Cuckoo clocks are popular, collectible timepieces. Decorated in a variety of traditional styles, cuckoo clocks are noted for the mechanical cuckoo that calls the hours. The cuckoo emerges from a small door set just below the clock's pointed roof. The roof is often topped by a carved crest. A crest c
How to Finish Wood Countertops
The two categories of finishes for wood countertops are food preparation oils and waxes or permanent waterproof finishes. A good finish for a wood countertop will seal the wood and block moisture from penetrating into the wood. Be aware that some species of wood will change color over time. To keep
Bleach & Red Cabbage Science Projects
Science projects allow students to see the concepts taught by their teacher. Chemical reactions can be seen by doing various different experiments using different elements. Red cabbage can be used to create a pH indicator, telling students which liquids are acids and which are bases. Adding bleach t
How to Reface a Dresser
Refacing is a good option to consider when you want a new bedroom dresser but can't afford to go out and buy one. Applying a new wood veneer to your old dresser can take a little time but can be a cost-effective way to give your piece of furniture an entirely different look.
Theileria Life Cycle
Theileria is a genus of protozoan parasites that infect domestic and wild members of ruminants. They are transmitted by ticks. There are two species of this parasite. Theileria parva, the more dangerous species, occurs mainly in eastern, central and southern Africa and causes the disease known as
How to Determine Magnification of a Microscope
The magnification of a microscope describes the increase in apparent size of an object compared with its actual size. An object magnified 10 times (10X) appears 10 times larger than it really is. Total magnification is the product of the ocular lens magnification and the objective lens magnification
What Is the Purpose of Breathing?
Breathing is one of the most natural and fundamental processes of life, but for a long time the nature of breathing was intractable and unknown. The cell was first discovered in the 19th century, revolutionizing our understanding of life. Almost everything about life is centered around the cell.
How to Make Really Slimy Slime With Borax
While you normally wouldn’t give children a handful of glue to play with, normal white craft glue combined with powdered Borax creates a hands-on slime that’s hard to resist. The slime, made possible due to the science of polymers, is both a solid and a liquid. Just slightly less solid t
How to Connect to an Existing Steel Beam
Most steel beams have multiple holes drilled into a plate located at the end of the beam. The holes allow a builder to connect an existing beam and a new beam together with heavy-duty bolts. For most home-building and renovation applications, bolt-together beams will meet all structural requirements
Use of a Computer for Space Research
Since the 1950's, computers have served many important roles in space exploration. In 2011, scientists, engineers and administrators use computers in every phase of a space project. Software on small computers runs robotic rovers, performing tasks such as driving, digging and analyzing. A computer o
Particle Board Uses for Crafts Projects
Particle board is formed by using a press to tightly compress wood chips, splinters, sawdust and a special resin into a single, flat piece of wood. This wood board is less expensive and more dense than normal wood. It is more suitable for craft projects that require covering the board, as it is less
How a Diode Works
IntroductionA diode is a two terminal analog device that allows an electrical current to flow in only one direction. Standard diodes are made from silicone and have two sides, the anode and the cathode. The anode is the positive terminal, the one you would connect to the (+) side of a...
What Is a Water Seal Vacuum Pump?
A water seal vacuum pump, also referred to as a liquid ring vacuum pump, uses water as an energy source for gas compression. Water pumps through a cylindrical rotor and creates a vacuum. That vacuum drives the spinning pump and compression process.
How to Make a Kite String Winder
Kids for years have been using just a stick wrapped with string to fly a kite. But when you want your kite to go up into the air hundreds of feet, you really need a better kite winder to help keep the string tangle-free. The good news is it doesn't take much time, money or effort to make your own ho
