Pipe Bomb
A pipe bomb is an improvised explosive device which uses a tightly sealed section of pipe (material), pipe filled with an explosive material. The containment provided by the pipe means that simple Explosive material#Low explosives, low explosives can be used to produce a relatively huge explosion due to the containment causing increased pressure, and the fragmentation of the pipe itself creates potentially lethal Fragmentation (weaponry), shrapnel. Premature detonation is a hazard of attempting to construct any homemade bomb, and the materials and methods used with pipe bombs make unintentional detonation incidents common, usually resulting in serious injury or death to the assembler. In many countries, the manufacture or possession of a pipe bomb is a serious crime, regardless of its intended use. Design The bomb is usually a short section of steel water pipe containing the explosive mixture and closed at both ends with steel or brass caps. A fuse is inserted into the pipe ...

Engineers From Illinois
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Electrical Engineering Academics
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Greek Orthodox Church
The term Greek Orthodox Church (Greek: Ἑλληνορθόδοξη Ἐκκλησία, ''Ellinorthódoxi Ekklisía'', ) has two meanings. The broader meaning designates "the entire body of Orthodox (Chalcedonian) Christianity, sometimes also called 'Eastern Orthodox,' 'Greek Catholic,' or generally 'the Greek Church. The narrower meaning designates "any of several independent churches within the worldwide communion of asternOrthodox Christianity that retain the use of the Greek language in formal ecclesiastical settings". Etymology Historically, the term "Greek Orthodox" has been used to describe all Eastern Orthodox churches, since the term "Greek" can refer to the heritage of the Byzantine Empire. During the first eight centuries of Christian history, most major intellectual, cultural, and social developments in the Christian Church took place in the Byzantine Empire or its sphere of influence, where the Greek language was widely spoken and used for most theological writin ...

Prostate Cancer
Prostate cancer is cancer of the prostate. Prostate cancer is the second most common cancerous tumor worldwide and is the fifth leading cause of cancer-related mortality among men. The prostate is a gland in the male reproductive system that surrounds the urethra just below the bladder. It is located in the hypogastric region of the abdomen. To give an idea of where it is located, the bladder is superior to the prostate gland as shown in the image The rectum is posterior in perspective to the prostate gland and the ischial tuberosity of the pelvic bone is inferior. Only those who have male reproductive organs are able to get prostate cancer. Most prostate cancers are slow growing. Cancerous cells may spread to other areas of the body, particularly the bones and lymph nodes. It may initially cause no symptoms. In later stages, symptoms include pain or difficulty urinating, blood in the urine, or pain in the pelvis or back. Benign prostatic hyperplasia may produce similar symptoms ...

Tourniquet
A tourniquet is a device that is used to apply pressure to a limb or extremity in order to stop the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A simple tourniquet can be made from a stick and a rope, but the use of makeshift tourniquets has been reduced over time due to their ineffectiveness compared to a commercial and professional tourniquet. This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur. Types There are three types of tourniquets: surgical tourniquets, emergency tourniquets, and rehabilitation tourniquets. Surgical tourniquets Silicone ring tourniquets, or elastic ring tourniquets, are self-contained mechanical devices that do not require any electricity, wires or tubes. The tourniquet comes in a variety of sizes. To determine the correct product size, the patient's limb circumference at the desired occlusion location should be measured, as well as their bloo ...

Necktie
A necktie, or simply a tie, is a piece of cloth worn for decorative purposes around the neck, resting under the shirt collar and knotted at the throat, and often draped down the chest. Variants include the ascot, bow, bolo, zipper tie, cravat, and knit. The modern necktie, ascot, and bow tie are descended from the cravat. Neckties are generally unsized but may be available in a longer size. In some cultures, men and boys wear neckties as part of office attire or formal wear. Women wear them less often. Neckties can also be part of a uniform. Neckties are traditionally worn with the top shirt button fastened, and the tie knot resting between the collar points. History Origins The necktie that spread from Europe traces back to Croatian mercenaries serving in France during the Thirty Years' War (1618–1648). These mercenaries from the Military Frontier, wearing their traditional small, knotted neckerchiefs, aroused the interest of the Parisians. Because of the differe ...
