E48 Particulate Bomb
The E48 particulate bomb was a U.S. biological sub-munition designed during the 1950s for use with the E96 cluster bomb. History In February 1950 a U.S. Army report prepared by William Creasy, a colonel within the U.S. bio-weapons program, noted that the E48 particulate bomb was in its final stages of development. Creasy also reported that the E48 had been successfully tested in three field trials.Endicott, Stephen and Hagerman, Edward. ''The United States and Biological Warfare: Secrets from the Early Cold War and Korea'',Google Books, Indiana University Press, 1998, pp. 67-68, (). Specifications The E48 particulate bomb was a sub-munition meant to be clustered in the E38 type cluster adapter, together the E48 and E38 constituted the E96 cluster bomb. In practice, the E96 and its payload of E48 sub-munitions was intended to be air-dropped from . The weapon could generate an elliptical aerosol agent cloud from this altitude that had major axes of .

Sub-munition
A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines, disperse chemical or biological weapons, or to scatter land mines. Some submunition-based weapons can disperse non-munitions, such as leaflets. Because cluster bombs release many small bomblets over a wide area, they pose risks to civilians both during attacks and afterwards. Unexploded bomblets can kill or maim civilians and/or unintended targets long after a conflict has ended, and are costly to locate and remove. Cluster munitions are prohibited for those nations that ratified the Convention on Cluster Munitions, adopted in Dublin, Ireland, in May 2008. The Convention entered into force and became binding international law upon ratifying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E96 Cluster Bomb
The E96 cluster bomb was an American anti-personnel biological cluster bomb developed in 1950. History A February 24, 1950 report prepared by William M. Creasy, a colonel in the Army Chemical Corps' Research and Engineering Division, characterized the E96 cluster bomb as in the final stages of development. According to Creasy's report, at the time the U.S. had no other biological weapon systems ready for use in battle. Specifications The E96 cluster bomb was a biological weapon designed to deliver an anti-personnel or anti-animal biological agent A biological agent (also called bio-agent, biological threat agent, biological warfare agent, biological weapon, or bioweapon) is a bacterium, virus, protozoan, parasite, fungus, or toxin that can be used purposefully as a weapon in bioterr .... It consisted of 104 E48 sub-munitions, each one weighing . The sub-munitions were clustered into an E38 cluster adapter and when used, would be dropped from generating an aerosol cloud ...

Ellipse
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity e, a number ranging from e = 0 (the limiting case of a circle) to e = 1 (the limiting case of infinite elongation, no longer an ellipse but a parabola). An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Analytically, the equation of a standard ellipse centered at the origin with width 2a and height 2b is: : \frac+\frac = 1 . Assuming a \ge b, the foci are (\pm c, 0) for c = \sqrt. The standard parametric equation is: : (x,y) = (a\cos(t),b\sin(t)) \quad \text \quad 0\leq t\leq 2\pi. Ellip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brucella Suis
''Brucella suis'' is a bacterium that causes swine brucellosis, a zoonosis that affects pigs. The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis, and may even affect joints and other organs. The most common symptom is abortion in pregnant susceptible sows at any stage of gestation. Other manifestations are temporary or permanent sterility, lameness, posterior paralysis, spondylitis, and abscess formation. It is transmitted mainly by ingestion of infected tissues or fluids, semen during breeding, and suckling infected animals. Since brucellosis threatens the food supply and causes undulant fever, ''Brucella suis'' and other ''Brucella'' species (''B. melitensis, B. abortus, B. ovis, B. canis'') are recognized as potential agricultural, civilian, and military bioterrorism agents. Symptoms and signs The most frequent clinical sign following ''B. suis'' infection is abortion in pregnant females, reduced milk ...

Anthrax
Anthrax is an infection caused by the bacterium '' Bacillus anthracis''. It can occur in four forms: skin, lungs, intestinal, and injection. Symptom onset occurs between one day and more than two months after the infection is contracted. The skin form presents with a small blister with surrounding swelling that often turns into a painless ulcer with a black center. The inhalation form presents with fever, chest pain and shortness of breath. The intestinal form presents with diarrhea (which may contain blood), abdominal pains, nausea and vomiting. The injection form presents with fever and an abscess at the site of drug injection. According to the USA's Centers for Disease Control and Prevention, the first clinical descriptions of cutaneous anthrax were given by Maret in 1752 and Fournier in 1769. Before that anthrax had been described only through historical accounts. The Prussian scientist Robert Koch (1843–1910) was the first to identify ''Bacillus anthracis'' as the bac ...

Botulin
Botulinum toxin, or botulinum neurotoxin (BoNT), is a neurotoxic protein produced by the bacterium ''Clostridium botulinum'' and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin causes the disease botulism. The toxin is also used commercially for medical and cosmetic purposes. The seven main types of botulinum toxin are named types A to G (A, B, C1, C2, D, E, F and G). New types are occasionally found. Types A and B are capable of causing disease in humans, and are also used commercially and medically. Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals. Botulinum toxins are among the most potent toxins known. Intoxication can occur naturally as a result of either wound or intestinal infection or by ingesting formed toxin in food. The estimated human lethal dose of type A toxin is 1.3 ...

Bacillus Globigii
''Bacillus'' (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum ''Bacillota'', with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural ''Bacilli'' is the name of the class of bacteria to which this genus belongs. ''Bacillus'' species can be either obligate aerobes which are dependent on oxygen, or facultative anaerobes which can survive in the absence of oxygen. Cultured ''Bacillus'' species test positive for the enzyme catalase if oxygen has been used or is present. ''Bacillus'' can reduce themselves to oval endospores and can remain in this dormant state for years. The endospore of one species from Morocco is reported to have survived being heated to 420 °C. Endospore formation is usually triggered by a lack of nutrients: the bacterium divides within its cell wall, and one side then engulfs the other. They are not true spores (i.e., not an offspring). Endospore formatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serratia Marcescens
''Serratia marcescens'' () is a species of rod-shaped, Gram-negative bacteria in the family Yersiniaceae. It is a facultative anaerobe and an opportunistic pathogen in humans. It was discovered in 1819 by Bartolomeo Bizio in Padua, Italy.Serratia marcescens. (2011, April). Retrieved from https://microbewiki.kenyon.edu/index.php/Serratia_marcescens ''S. marcescens'' is commonly involved in hospital-acquired infections (HAIs), also called nosocomial infections, particularly catheter-associated bacteremia, urinary tract infections, and wound infections, and is responsible for 1.4% of HAI cases in the United States. It is commonly found in the respiratory and urinary tracts of hospitalized adults and in the gastrointestinal systems of children. Due to its abundant presence in the environment, and its preference for damp conditions, ''S. marcescens'' is commonly found growing in bathrooms (especially on tile grout, shower corners, toilet water lines, and basins), where it ...

Biological Weapon Delivery Systems
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
