Utilization of Biodegradable Kitchen Wastes into Organic Fertilizer Using Earthworms * Abstract One of the effective means to at least lessen the occurrence of our present garbage disposal problem is through the use of methods that are non-toxic‚ less expensive‚ less-harmful‚ and yet equally effective. This project aims to provide for a natural and effective way of disposing garbage. During the experiment‚ kitchen wastes were collected. The materials were shredded and placed in garbage bags

birthplace of the needle and syringe. Less than a mile from here in this direction‚ in 1853 a Scotsman filed his very first patent on the needle and syringe. His name was Alexander Wood‚ and it was at the Royal College of Physicians. This is the patent. What blows my mind when I look at it even today is that it looks almost identical to the needle in use today. Yet‚ it ’s 160 years old. 0:43 So we turn to the field of vaccines. Most vaccines are delivered with the needle and syringe‚ this 160-year-old technology

The Decomposition of Baking Soda Purpose: - To determine the correct balanced equation for the decomposition of baking soda using % yield. PreLab Notes: Sodium Bicarbonate (Baking Soda) decomposes when heated yielding both gaseous products and solid products. The production of gas makes baking soda a leavening agent in baked goods. The trapped bubbles of gas give muffins and cakes a lighter‚ airier texture. When heated‚ baking soda decomposes in one of the following unbalanced equations.

The Science of Catalysts and Catalytic Converters Hosam Sadek February 19th‚ 2013 Catalyst is a term that is used for a chemical agent that selectively increases the rate of a reaction without itself being affected. In the human body‚ enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. These catalysts participate in the reactions‚ but are neither reactants nor products of the reaction they catalyze. The only difference between a catalyzed reaction and

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

<b>Thesis Statement</b><br>The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb‚ which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.<br><br><b>The Hydrogen Bomb</b><br>The Atomic Bomb Was A Essential
