The Effective Fermentation to Ethanol From Cellulose
Cellulose is the most abundant biological macromolecule on Earth, the major component of wood and plant cell walls. If it could be reliably and efficiently turned into fuel such as ethanol, cellulose would offer human society a sustainable source of energy. Many scientists are working to make that d
Types of Plankton in the Florida Keys
The Florida Keys archipelago contains North America's largest and only living coral barrier reef. This complex ecosystem supports diverse plants and animals, including drifting microorganisms called plankton, which sit at the base of the coral reef food web.

Nickel electroplating provides a protective coating that is also at
Cheap Wood for Beginner Practice Furniture Making
Woodworking, especially furniture-making, can be a very rewarding hobby. Crafting something with your own hands from simple materials provides a great sense of satisfaction. And it's all the better when you are able to create something functional as you develop marketable skills. As a beginner furni
How to Set Up Pitch Curve For a Belt CP
Most radio-controlled (RC) vehicle enthusiasts consider the helicopter to be the most difficult RC to navigate. Flying your Esky Belt CP requires considerable patience and practice; however, making the correct adjustments to your aircraft will determine how quickly you become a successful pilot. Lea
Black Tourmaline Mythology
Tourmaline is often mistaken for other types of gemstones, but it is distinguished by certain intriguing electrical properties.

How to Build Styrofoam RC Airplanes
RC foam planes are light and have very little surface area resistance, so they fly well. These planes are a great craft for both children and adults due to their popularity of being both robust and lightweight. They can also handle rougher landings as you are learning to fly radio control. Using foa
How to Calculate Downhole Hydrostatic Pressure
Groundwater production wells and groundwater monitoring wells serve as scientific windows for peering into underground aquifers. This lets researchers model the flow of subsurface water and predict the future performance of aquifers and wells. One measurable aquifer characteristic is the hydrostatic
How to Find an Unknown Radius
A circle is defined as every point equidistant from a single center point. Because this definition creates a constant shape, there is also a constant relationship between the distance around the circle, called circumference, and the distance across its center, called the diameter. This number repres
How to Sharpen a Head Knife With Leather
