Faculae: Bright temporary patches on the surface of the sun, usually (although not always) associated with sunspots.Faculae frequentlyappear in a position near which a spot group is about to appear, and may persist for some time in a region of a group which has disappeared.

Lindberg Charles Augustus Jr. (1902-1974)

...known as "Lucky Lindy" and "The Lone Eagle", was an American aviator famous for piloting the first solo non-stop flight across the Atlantic Ocean in 1927.

Some believe Lindbergh tarnished his good name by his leadership in the movement to keep the US out of World War II. He was a great advocate for the peace movement and the peaceful resolution of conflict with Germany.

Millibar: A unit which is used as a measure of atmospheric pressure. It is equal to 1000 dynes per square centimetre. The standard atmospheric pressure is  1013.25 millibars (75.97 centimetres of mercury).

Occulltation: The covering up of one celestial body by another. Thus the moon may pass in front of a star or ( occasionally) a planet; A planet may occult a star; and there have been cases when one planet has occulted another- for instance, Venus occulted Mars in 1950. Strickly speaking, solar eclipses are occultations of the Sun by the Moon.

Paragonimiasis

http://pathmicro.med.sc.edu/parasitology/Paragonimus-lc.gif

Paragonimus westermani (Lung Fluke)

Epidemiology
Lung fluke is most commonly encountered in parts of Asia, Africa and South America.
Morphology
It is a plump reddish brown oval worm measuring 10 by 4 mm. The ovum measures 85 by 55 micrometers
Life cycle
Lung fluke infects man (and domestic carnivores) when crabmeat infested with encysted metacercaria is consumed. The metacercaria reach the small intestine, exit their shell and bore their way, as young flukes, through the intestinal wall, through the thoracic diaphragm and penetrate the lung. There, they become enclosed in 1 to 2 cm cysts and reach maturity. The eggs are found in the sputum or, if swallowed, in the feces, 2 to 3 months after infection. The eggs, when introduced in fresh water produce a miracidia which penetrates the suitable snail. In the snail they develop into cercaria which break out in water and penetrate gills, muscle or viscera of fresh water crabs and become encysted in flesh as metacercaria.
Symptoms
The fluke provokes the development of a fibrous tissue capsule with bloody purulent material containing eggs. There is inflammatory infiltrate around the capsule. The symptoms include a dry cough, followed by production of blood stained rusty brown sputum. Pulmonary pain and pleurisy may develop. Worms may migrate to the brain where they lay eggs and cause a granulomatous abscess resulting in symptoms similar to epilepsy.
Diagnosis
Diagnosis is based on history and symptoms. Eggs are found in rust colored sputum, often being examined for tuberculosis.
Treatment and control
Praziquantel taken orally is quite effective. Adequate cooking of crustaceans is a preventive measure. Improved sanitary conditions have lowered the infection rate in endemic areas.

I did a talk on this subject and I think it went well. Amazing how nervous you think you will be doing a talk. Once I went over it with my partner a few times I was actually confident and couldn't wait to do it :-D.

Tension (mechanics)


Tension is a reaction force applied by a stretched string (rope or a similar object) on the objects which stretch it. The direction of the force of tension is parallel to the string, towards the string.

Tension exists also inside the string itself: if the string is considered to be composed of two parts, tension is the force which the two parts of the string apply on each other. The amount of tension in the string determines whether it will break, as well as its vibrational properties, which are used in musical instruments.

The magnitude of the force of tension typically increases with the amount of stretching. For small stretching, the force is often described by Hooke's law.

String-like objects in relativistic theories, such as the strings used in some models of interactions between quarks, or those used in the modern string theory, also possess tension. These strings are analyzed in terms of their world sheet, and the energy is then typically proportional to the length of the string. As a result, the tension in such strings is independent of the amount of stretching.

Von Willebrand Factor

http://www.soe.ucsc.edu/classes/bme220/Spring05/homework1/alexgw/vwf/vwf-2-highlit-cys.jpg

Von Willebrand factor (VWF) is a protein that is involved in blood clotting after injury to a blood vessel. When a vessel is torn, platelet cells collect in the cut region and create a fibrous mesh that seals off the area and stops further bleeding. The VWF serves two major functions: it helps attach platelets to the site of blood vessel injury, and it helps transport the "factor VIII" (factor clotting protein to the site of injury.

There are several inherited genetic disorders related to abnormal function of VWF. Symptoms may be similar to those of hemophilia, although the underlying causes are different. Some forms of VWF are quite mild and may remain undiagnosed, while others are more like hemophilia and result in serious bleeding and blood clotting problems.

Wallace Alfred Russel


Alfred Russel Wallace, OM, FRS (January 8, 1823 – November 7, 1913) was a Welsh naturalist, explorer, geographer, anthropologist and biologist. He independently proposed a theory of natural selection which prompted Charles Darwin to publish his own more developed and researched theory sooner than he had intended. Wallace is sometimes called the "father of biogeography".

The Zener Effect
With the application of sufficient reverse voltage, a p-n junction will experience a rapid avalanche breakdown and conduct current in the reverse direction. Valence electrons which break free under the influence of the applied electric field can be accelerated enough that they can knock loose other electrons and the subsequent collisions quickly become an avalanche. When this process is taking place, very small changes in voltage can cause very large changes in current. The breakdown process depends upon the applied electric field, so by changing the thickness of the layer to which the voltage is applied, zener diodes can be formed which break down at voltages from about 4 volts to several hundred volts.
