Don W. Fawcett
Don Wayne Fawcett (March 14, 1917 - May 7, 2009) was a pioneer of electron microscopy and one of its greatest practitioners for studying the organization of cells and tissues. His greatest achievement was his description of the structure of spermatozoa and the male reproductive system. Early life Don Fawcett was born in 1917 on a farm in Iowa, where his father and grandfather had raised purebred sheep and cattle until his father's poor health forced the family to leave the farm and move to Boston, where Fawcett's father managed a successful wool business. Fawcett attended high school at the Boston Latin School. Upon graduation, he matriculated at Harvard College in 1934, followed by Harvard Medical School in 1938, where he connected with anatomy professor George B. Wislocki. "I stole as much time as I could from my course work to do independent research on projects that included studies on the vascular bundles of aquatic mammals, and the amedullary bones of the Florida manatee" ...

Bandage
A bandage is a piece of material used either to support a medical device such as a dressing or splint, or on its own to provide support for the movement of a part of the body. When used with a dressing, the dressing is applied directly on a wound, and a bandage is used to hold the dressing in place. Other bandages are used without dressings, such as elastic bandages that are used to reduce swelling or provide support to a sprained ankle. Tight bandages can be used to slow blood flow to an extremity, such as when a leg or arm is bleeding heavily. Bandages are available in a wide range of types, from generic cloth strips to specialized shaped bandages designed for a specific limb or part of the body. Bandages can often be improvised as the situation demands, using clothing, blankets or other material. In American English, the word ''bandage'' is often used to indicate a small gauze dressing attached to an adhesive bandage. Types Gauze bandage (common gauze roller bandage) T ...

Darkroom
A darkroom is used to process photographic film, make Photographic printing, prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water. Darkrooms have been used since the inception of photography in the early 19th century. Darkrooms have many various manifestations, from the elaborate space used by Ansel Adams to a retooled ambulance wagon used by Timothy H. O'Sullivan. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium. Due to the popularity of color photography and complexity of List of photographic processes, processing color film (''see C-41 process'') and printing color photographs and also to the rise, first of Instant camera, instant photography te ...

Diamond Knives
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) can color a diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, oran ...

Microtome
A microtome (from the Greek ''mikros'', meaning "small", and ''temnein'', meaning "to cut") is a cutting tool used to produce extremely thin slices of material known as ''sections'', with the process being termed microsectioning. Important in science, microtomes are used in microscopy for the microscope slide, preparation of samples for observation under transmitted visible light, light or electron radiation. Microtomes use steel, glass or diamond blades depending upon the specimen being sliced and the desired thickness of the sections being cut. Steel blades are used to prepare histological sections of animal or plant tissues for light microscopy. Glass knives are used to slice sections for light microscopy and to slice very thin sections for electron microscopy. Industrial grade diamond knives are used to slice hard materials such as bone, teeth and tough plant matter for both light microscopy and for electron microscopy. Gem-quality diamond knife, diamond knives are also used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Biology
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. Cell biology is the study of the structural and functional units of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several microscopy techniques, cell culture, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fiel ...

European Theater Of World War II
The European theatre of World War II was one of the two main Theater (warfare), theatres of combat during World War II, taking place from September 1939 to May 1945. The Allies of World War II, Allied powers (including the United Kingdom, the United States, the Soviet Union and France) fought the Axis powers (including Nazi Germany and Fascist Italy) on both sides of the continent in the Western Front (World War II), Western and Eastern Front (World War II), Eastern fronts. There was also conflict in the Scandinavian, Mediterranean and Balkan regions. It was an intense conflict that led to at least 39 million deaths and a dramatic change in the balance of power in the continent. During the 1930s, Adolf Hitler, the leader of Nazi Germany, expanded German territory by annexing all of Austria and the Sudetenland region of Czechoslovakia in 1938. This was motivated in part by Racial policy of Nazi Germany, Germany's racial policy that believed the country needed to expand for the p ...

Battalion Aid Station
{{no footnotes, date=February 2013 In the United States Army and Marine Corps, a battalion aid station is a medical section within a battalion's support company. As such, it is the forwardmost medically staffed treatment location. During peacetime, it is led by a medical operations officer, a first lieutenant in the Army Medical Service Corps or a lieutenant from the Navy Medical Corps. During combat, a commissioned medical doctor with the Army Medical Corps may assume leadership of the platoon and direct medical operations. However, in the Army, the medical service officer normally retains control of training, planning, and administration of the platoon while the doctor in charge directs medical care. The primary mission of the battalion aid station is to collect the sick and wounded from the battalion and stabilize the patients' condition. The battalion aid station belongs to, and is an organic component of, the unit it supports. It may be split into two functional units ...

Burn
A burn is an injury to skin, or other tissues, caused by heat, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). Most burns are due to heat from hot fluids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters, and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can re ...

Cocoanut Grove Fire
The Cocoanut Grove fire was a nightclub fire which took place in Boston, Massachusetts, on November 28, 1942, and resulted in the deaths of 492 people. It is the deadliest nightclub fire in history and the third-deadliest single-building fire (after the September 11 attacks and Iroquois Theatre fire). The Cocoanut Grove was one of Boston's most popular nightspots, attracting many celebrity visitors. It was owned by Barnet "Barney" Welansky, who was closely connected to the Mafia and to Mayor Maurice J. Tobin. Fire regulations had been flouted: some exit doors had been locked to prevent unauthorized entry, and the elaborate palm tree décor contained flammable materials. The air conditioning system was filled with a flammable gas because of the wartime shortage of nonflammable Freon. During the first Thanksgiving weekend since the U.S. had entered World War II the Grove was filled to more than twice its legal capacity. The fire was initiated by an electrical short, and accelerated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgery
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery.
