Diogenes Angelakos
Diogenes James Angelakos (July 3, 1919 – June 7, 1997) was an American electrical engineer and professor emeritus of electronic engineering at the University of California, Berkeley, who served as the director of the Electronics Research Laboratory for 20 years. He is credited with building up the research group into one of the university's biggest research labs. He is considered a pioneer in the fields of microwaves, antennas and electromagnetic waves. Engineering career He graduated from University of Notre Dame with a B.S. in electrical engineering in 1942 and then receives his M.S. (1946) and Ph.D. (1950) in the same field from Harvard University. In 1964, he was appointed director of the Electronics Research Laboratory at the University of California, Berkeley. He was a Fellow, and later a Life Fellow, of the Institute of Electrical and Electronics Engineers and an honorary member of the Hellenic Physical Society. Among his awards were the "Greek Independence Medal for ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pipe Bomb
A pipe bomb is an improvised explosive device (IED) that uses a tightly sealed section of pipe filled with an explosive material. The containment provided by the pipe means that simple low explosives can be used to produce a relatively large explosion due to the containment causing increased pressure. The fragmentation of the pipe itself creates potentially lethal shrapnel. Premature detonation is a hazard of attempting to construct any homemade bomb. The materials and methods used with pipe bombs often result in unintentional detonation, 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 with a lead running out through a hole in the side or capped end of the pipe. The ...

Engineers From Illinois
Engineers, as practitioners of engineering, are professionals who invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim 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 , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering dis ...

Electrical Engineering Academics
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrica ...

Prostate Cancer
Prostate cancer is the neoplasm, uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Abnormal growth of the prostate tissue is usually detected through Screening (medicine), screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels. Those with high levels of PSA in their blood are at increased risk for developing prostate cancer. Diagnosis requires a prostate biopsy, biopsy of the prostate. If cancer is present, the pathologist assigns a Gleason score; a higher score represents a more dangerous tumor. Medical imaging is performed to look for cancer that has spread outside the prostate. Based on the Gleason score, PSA levels, and imaging results, a cancer case is assigned a cancer staging, stage 1 to 4. A higher stage signifies a more advanced, more dangerous disease. Most prostate tumors remain small and cause no health problems. These are managed with active surveillance of prostate cancer, ...

Tourniquet
A tourniquet is a device that is used to apply pressure to a limb or extremity in order to create ischemia or stopping 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. History During Alexander the Great’s military campaigns in the fourth century BC, tourniquets were used to stanch the bleeding of wounded soldiers. Romans used them to control bleeding, especially during amputations. These tourniquets were narrow straps made of bronze, using only leather for comfort. In 1718, French surgeon Jean Louis Petit developed a screw device for occluding blood flow in surgical sites. Before this invention, the ''tourniquet' ...

Necktie
A necktie, long tie, or simply a tie, is a cloth article of formal neckwear or office attire worn for decorative or symbolic purposes, resting under a folded shirt collar or knotted at the throat, and usually draped down the chest. On rare occasions neckties are worn above a winged shirt collar. However, in occupations where manual labor is involved, the end of the necktie is often tucked into the button line front placket of a dress shirt, such as the dress uniform of the United States Marine Corps. Neckties are usually paired with suit jackets or sport coats, but have often been seen with other articles, such as v-neck sweaters. Neckties are reported by fashion historians to be descended from the regency era cravat. Adult neckties are generally unsized in length but may be available in a longer sizes for taller persons. Widths are matched to the width of a suit jacket lapel. Neckties were originally considered " menswear," but are now considered unisex items in most We ...
