A hybrid airship is an aircraft that combines the technologies found in conventional aircrafts and airships in starting and maintaining its flight. It will have the large airbag within a cylindrical body so it looks like a conventional airship, but it will also have wings and rudders like a regular airplane. Airships, Balloons and Conventional Aircrafts An airship (better known as a dirigible or blimp) is an aircraft that uses a large inflatable compartment or chamber which is filled with a gas. The gas (usually hydrogen or helium) used in Read More

As matter is composed of many particles such as electrons and protons, antimatter is composed of antielectrons (also called positrons) and antiprotons. The antimatter concept also tells us that all matter has corresponding and equivalent antimatter that possess opposite properties. For instance the hydrogen atom will have corresponding antimatter called antihydrogen and all of the antihydrogen's particles will have properties opposite those of the normal hydrogen particles. A hydrogen atom's proton has a positive charge while the antiproton of the antihydrogen will have a negative charge. However, the antihydrogen's antiproton Read More

Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing profits for the company that produced it. The ideal pH for products using potassium benzoate as a preservative is below 4.5 because that is where it exists as benzoic acid. Acidic food or beverages such Read More

Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the electromagnetic repulsion is strong enough to balance the weight of the object. Methods for Obtaining Magnetic Levitation There are different methods for obtaining Magnetic Levitation. For heavy objects, the main are electromagnetic suspension and electrodynamic Read More

Sneezing is either an annoying or relieving thing for most people. The process of sneezing can occur in many different ways. This irritation can cause misery in some people who simply wish their sneezing to stop. Preventative measures for sneezing is also a possibility for some people. The Biological Process of a Sneeze The actual medical term for a sneeze is known as a sternutation. Sternutations occur when there is reason for the body to clear debris or buildup of mucus from the nasal passages and internal nose hairs. When the microscopic particles are introduced Read More

A yottabyte is an amount of information that equals one septillion bytes or one quadrillion gigabytes. This amount can also be measured as 1024 bytes. Yottabytes should not be confused with the term “yobibyte,” which is used to express a measurement that is much larger. Although yottabytes are currently an imaginary measurement, servers or even personal hard drives may use them some day. What Uses Yottabytes? Currently, no device in the world uses yottabytes. In fact, all of the combined storage space on every hard drive in the world would Read More

A common law enforcement practice known as "speed traps" or "speed trapping" is based on one universal factor: Almost everyone speeds. Everyone has their reasons but most people speed on occasion just because they can. While this excessive acceleration is usually harmless as drivers have enough time to slow down during emergencies, many fatal car accidents are caused by everyday people who just didn't bother to slow down. Law enforcement personnel struggle to combat this crime but most people slow down when they see a police officer in the area. Read More

A Magnetic Resonance Angiography (MRA) is a type of Magnetic Resonance Imaging (MRI) scan that allows doctors to look at a patient’s blood vessels without using X-rays or other forms of radiation. MRAs allow the doctor to examine both the patient’s blow flow as well as the health of the blood vessels themselves. By using MRAs, doctors can discover any possible problems resulting from low blood flow and identify the source of the problem. MRAs can identify narrow regions of the patient’s blood vessels, damaged portions of the aorta in Read More

Bunsen burners are used in laboratories to heat materials or substances for experiments. The burners are gas-driven and have a flame that is adjusted by the amount of air and gas that is supplied to the unit. Many laboratories have started to use electric hot plates in place of Bunsen burners for experiments because they are less flammable and produce a cleaner heat. However, many academicians and researchers still use the traditional burner. How is a Bunsen Burner Designed? A Bunsen burner has a metal tube that is placed at Read More

A beer battery is one of the new innovations in power generation that makes use of bacteria that consume sugar and brewery water waste to produce electricity. Beer battery is also called Microbial Fuel Cell or MFC. The bacteria used actually break down the sugar, alcohol and starch content of the waste water to produce the electricity. The process has carbon dioxide and water by-products. Moreover, brewery waste water is biodegradable. Thus, it is very earth-friendly. The beer battery is also a renewable resource. How a Beer Battery Generates Electricity Read More
