Thyristor
The thyristor is a solid-state semiconductor device with
four layers of alternating N and P-type material
.
They act as a
switch
, conducting when their gate receives a current pulse, and continue to conduct for as long as they are forward biased.
Some sources define silicon controlled rectifiers and thyristors as synonymous; others define SCRs as a subset of thyristors. Among the latter, the International Electrotechnical Commission 60747-6 standard stands out.
Non-SCR thyristors include devices with more than four layers, such as triacs and DB-GTOs

A
flatoxins
(Aspergillus flavus toxins = aflatoxins)
http://www.aflatoxin.info/images/afla_2.jpg
http://www2.dpi.qld.gov.au/images/2326.jpg
http://www.moldbacteria.com/Aspergillusflavus.gif
http://www.osel.cz/_img/img1094798100.jpg
Aflatoxins are naturally occurring mycotoxins that are produced by many species of
Aspergillus
, a fungus, most notably
Aspergillus flavus and Aspergillus parasiticus
. Aflatoxins are toxic and carcinogenic. After entering the body, aflatoxins are metabolized by the liver to a reactive intermediate, aflatoxin M1, an epoxide. Aflatoxin is frequently misspelled as alfatoxin.
Aspergillus
is common and widespread in nature and are most often found when crops are exposed to a high humidity environment over a long period of time or are damaged in stressful conditions such as drought, a condition which lowers the barrier to entry.
The native habitat of Aspergillus is in soil, decaying vegetation, hay, and grains undergoing microbiological deterioration and it invades all types of organic substrates whenever and wherever the conditions are favorable for its growth. Favorable conditions include
high moisture content
(at least 7%) and
high temperature
.
Crops which are frequently affected include
cereals
(maize, sorghum, pearl millet, rice, wheat), oilseeds (peanut, soybean, sunflower, cotton),
spices
(chile peppers, black pepper, coriander,
turmeric
, ginger), and tree
nuts
(almond, pistachio, walnut, coconut, brazil nut).
The toxin can also be found in the milk of animals which are fed contaminated feed.

Carl Edward Sagan
From wikipedia
Carl Edward Sagan (November 9, 1934 – December 20, 1996) was an American astronomer and astrobiologist and a highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series Cosmos: A Personal Voyage, which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history.[1] A book to accompany the program was also published. He also wrote the novel Contact, the basis for the 1997 Robert Zemeckis film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, humanism, and the scientific method.
