ala azar
(Visceral leishmaniasis)
http://www.brown.edu/Courses/Bio_160/Projects2000/Leishmaniasis/amastigotes.jpg
...In order to develop a successful parasitic relationship with its host, the
leishmania
must evade both the innate and adaptive immune responses. When leishmania first enters the human body, it is in the promastigote form.
Promastigotes
are engulfed by macrophages but are resistant to proteolysis and degradation in the phagosome. Once inside the macrophage, the organism is termed an
amastigote
.
By continuing to live inside the macrophage, leishmania effectively avoids the humoral branch of the immune system. During each of the steps described, the protozoa evade and at times manipulate the human immune system and avoid digestion.

iquid crystal display
From Wikipedia, the free encyclopedia
A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is prized by engineers because it uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.

derived from blood monocytes:
- about 6% of all WBCs; largest leukocyte 12-15 micrometers; nucleus shape varies from kidney-shaped to horseshoe-shaped, but always indented; lighter staining than lymphocytes
- cytoplasm without granules and stains pale blue-gray
- in contrast to neutrophils, are relatively long-lived
- are distributed throughout connective tissue and around the basement tissue of small blood vessels
- monocytes are phagocytic; when monocytes leave bloodstream they rapidly transform to macrophages that are very actively phagocytic ingesting bacteria, dead cells, tissue debris; also stimulate antibody production by lymphocytes.
- defend against pathogens which reside within host cells.

N
othing
From Wikipedia, the free encyclopedia
Nothing is the lack or absence of anything. Colloquially, however, the term is often used to describe a particularly unimpressive thing, event, or object.
In mathematics, nothing does not have a technical meaning. It could be said that a set contains "nothing" if and only if it is the empty set, in which case its cardinality (or size) is zero. In other words, the word "nothing" is an informal term for an empty set.
In physics, the word nothing is not used in any technical sense. A region of space is called a vacuum if it does not contain any matter. But it can contain physical fields. In fact, it is practically impossible to construct a region of space which contains no matter or fields, since gravity cannot be blocked and all objects at a non-zero temperature radiate electromagnetically. However, supposing such a region existed, it would still not be "nothing", since it has properties and a measurable existence as part of the quantum-mechanical vacuum.
The concept of "nothing" has been studied throughout history by philosophers and theologians; many have found that careful consideration of the notion can easily lead to the logical fallacy of reification. (If one does not believe that nothing is no thing.) The understanding of "nothing" varies widely between cultures, especially between Western and Eastern cultures and philosophical traditions. For instance, emptiness, unlike "nothingness," is considered a state of mind in Buddhism .

rnithorhynchus
http://images.encarta.msn.com/xrefmedia/sharemed/targets/images/pho/t049/T049934A.jpg
The
Platypus
(Ornithorhynchus anatinus) is a
semi-aquatic mammal
endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of
monotremes
, the
only mammals that lay eggs instead of giving birth to live young
.
It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record.
The bizarre appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some considering it an elaborate fraud. It is one of the few venomous mammals; the male Platypus has a spur on the hind foot which delivers a poison capable of causing severe pain to humans. The unique features of the Platypus make it an important subject in the study of evolutionary biology and a recognizable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of the Australian 20-cent coin.
Until the early 20th century it was hunted for its fur, but it is now protected throughout its range. Although captive breeding programs have had only limited success and the Platypus is vulnerable to the effects of pollution, it is not under any immediate threat.

P
arabola
From Wikipedia, the free encyclopedia
In mathematics, the parabola (from the Greek: παραβολή) (IPA pronunciation: /pəˈrab(ə)lə/) is a conic section generated by the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. A parabola can also be defined as locus of points in a plane which are equidistant from a given point (the focus) and a given line (the directrix).
A particular case arises when the plane is tangent to the conical surface. In this case, the intersection is a degenerate parabola consisting of a straight line.
The parabola is an important concept in abstract mathematics, but it is also seen with considerable frequency in the physical world, and there are many practical applications for the construct in engineering, physics, and other domains.

emote control
From Wikipedia, the free encyclopedia
A remote control is an electronic device used for the remote operation of a machine.
The term remote control can be also referred to as "remote" or "controller" when abbreviated. It has been known by many other names as well, such as the "clicker," etc. Commonly, remote controls are used to issue commands from a distance to televisions or other consumer electronics such as stereo systems and DVD players. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. In fact, for the majority of modern devices with this kind of control, the remote contains all the function controls while the controlled device itself only has a handful of essential primary controls. Most of these remotes communicate to their respective devices via infrared (IR) signals and a few via radio signals. They are usually powered by small AAA or AA size batteries.
Guess what these are ?...go on...have a guess !!...tricky eh ?...well I don't know !!

- Smart Gels
Polymer gels that can expand or contract by up to 1000 times in volume.
According to TECHTALK published by the MIT News Office, "Smart gels or polymer gels are a class of materials that expand or contract when triggered by tiny changes in temperature, light, a solvent or other stimulus."
Polymer gels have the ability to make large but reversible changes in volume allowing for the invention of smart gels that could deliver various agents and materials at specific events for countless purposes. For example, uses for smart gels could include cleaning up oil spills, creating cosmetics adaptable to skin pH, or even serving as miniature artificial valves and muscles.
Toyoichi Tanaka
Father of Smart Gels
Toyoichi Tanaka
was born in Nagaoka-city, Japan in 1946. He received his BS in (1968), MS (1970) and DSc (1973) in physics from the University of Tokyo.
He joined the MIT physics faculty in 1975. Toyoichi Tanaka married Tomoko Tahira in 1970.
In 1992, Toyoichi Tanaka co-founded GelMed Inc and its sister company, Gel Sciences Inc. He also co-founded Buyo-Buyo, Inc.
Toyoichi Tanaka was the winner of the 38th Toray Science and Technology Prize from the Toray Science Foundation in Japan and the 1994 Inoue Prize for Science. He was awarded the Vinci d'Excellence in France for his work in 1993.

FRANK J.
Z
AMBONI
(1901-1988)
Ice resurfacing machine
In 1949, Frank Zamboni invented the machine used today in skating rinks all over the world to clean and polish the ice surface on the spot.
Born in 1901, Zamboni was a natural mechanic and innovative thinker. He moved to Southern California at the age of 21, to work in auto repair at his elder brother's garage, but soon decided to enter the refrigeration business. At that time, the dairy and produce industries relied heavily on ice for storage and transport, so Zamboni and another brother built a factory to produce block ice.
Over the years, the refrigeration technology used in warehouses and boxcars made great advances, thanks to inventors like W. H. Carrier and Frederick McKinley Jones. Never one to be left in the cold, Zamboni found a new venue for his expertise. In 1939, he, his brother and a cousin built Iceland Skating Rink in Paramount, California --- at 20,000 sq. ft., one of the largest rinks in the country. Zamboni soon added a domed roof over the rink: the dome helped defend the ice surface from the California sun, but could not prevent everyday defects in the ice, namely the chipping and gouging that inevitably result from use.
To renew the ice surface, a team of three or four workers had to scrape the ice with a tractor, then shovel away the shavings, hose down and squeegee the surface, and wait for the ice to set again: the process took over an hour, each time. In 1942, Zamboni began to transform a tractor into a unified ice surface scraper and smoother, one that could resurface the ice at one pass.
After seven years of experiments, Zamboni succeeded: an adjustable blade in a frame behind the machine shaved the ice smooth; the resultant shavings were then swept up and conveyed into a large holding tank; an apparatus at the back of the resurfacer rinsed and squeegeed the ice as the machine moved ahead, leaving a layer of water shallow enough that it bonded to the ice below almost instantly. In 1949, the "Model A Zamboni Ice Resurfacer" became both patented (#2,642,679) and marketable.
Zamboni's best help in marketing his invention came from Olympic skater Sonja Henie. In 1950, she saw the Zamboni® in action while practicing at Paramount Iceland, and immediately ordered one for her national tour. Later, she took a Model B with her to Europe. It was not long before the Ice Capades, and then various recreational and sports skating rinks, were clamoring for a Zamboni® of their own.
As ice skating continued to rise in popularity in the 1950s and '60s, Zamboni kept improving his machines: his HD model (1964) set the standards for the industry that he singlehandedly created; the latest models (1978-present) feature a liquid-cooled engine or run on electric batteries.
Today's machines are still manufactured at Zamboni's original factory; their proving ground is still the nearby Paramount Iceland. Frank Zamboni died in 1988, but as his company looks ahead to its 50th anniversary (1999), the evidence of his success in invention can be seen around the world, from Olympic arenas to neighborhood ice rinks.
