Wankel engine
From Wikipedia, the free encyclopedia


 [ Invalid Attachment ]


The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle is generally generated in a space between the inside of an oval-like epitrochoid-shaped housing and a roughly triangular rotor. This design delivers smooth high-rpm power from a compact, lightweight engine.

The engine was invented by German engineer Felix Wankel. He began its development in the early 1950s at NSU Motorenwerke AG (NSU) before completing a working, running prototype in 1957. NSU then subsequently licenced the concept to other companies across the globe, who added more efforts and improvements in the 1950s and 1960s.

Because of their compact, lightweight design, Wankel rotary engines have been installed in a variety of vehicles and devices such as automobiles and racing cars, aircraft, go-karts, personal water crafts, and auxiliary power units.

 Xing ,Yi (Chinese: 一行; pinyin: Yī Xíng; Wade-Giles: I-Hsing, 683–727), born Zhang Sui (张遂), was a Chinese astronomer, mathematician, mechanical engineer, and Buddhist monk of the Tang Dynasty (618–907). His astronomical celestial globe was the first to feature a clockwork escapement mechanism, the first in a long tradition of Chinese astronomical clockworks.

Ahmed Hassan Zewail (Arabic: أحمد حسن زويل) (born February 26, 1946 in Damanhur, Egypt) is an Egyptian American scientist, and the winner of the 1999 Nobel Prize in Chemistry for his work on femtochemistry.

Femtochemistry is the science that studies chemical reactions on extremely short timescales, approximately 10–15 seconds (this is one femtosecond, hence the name).

In 1999, Ahmed H. Zewail received the Nobel Prize in Chemistry for his pioneering work in this field.

Zewail’s technique uses flashes of laser light that last for a few femtoseconds. Femtochemistry is the area of physical chemistry that addresses the short time period in which chemical reactions take place and investigates why some reactions occur but not others. Zewail’s picture-taking technique made possible these investigations. One of the first major discoveries of femtochemistry was to reveal details about the intermediate products that form during chemical reactions, which cannot be deduced from observing the starting and end products. Many publications have discussed the possibility of controlling chemical reactions by this method, but this remains controversial.

The simplest approach and still one of the most common techniques is known as pump-probe spectroscopy. In this method, two or more optical pulses with variable time delay between them are used to investigate the processes happening during a chemical reaction. The first pulse (pump) initiates the reaction, by breaking a bond or exciting one of the reactants. The second pulse (probe) is then used to interrogate the progress of the reaction a certain period of time after initiation. As the reaction progresses, the response of the reacting system to the probe pulse will change. By continually scanning the time delay between pump and probe pulses and observing the response, workers can follow the progress of the reaction in real time.

Aberration of light

An annual apparent shift in the positions of stars against the background of more distant stars,
caused by the earth's orbital motion. The shift appears as a circle, an ellipse or even a short line, depending on the distance of the star above or below the earth's orbital plane.

A cyst is a closed sac having a distinct membrane and division on the nearby tissue. They may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, the cyst could go away by itself or will have to be removed using surgery.

The Doppler effect (or Doppler shift), named after Christian Doppler, is the change in frequency and wavelength of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is higher than the emitted frequency when the siren approaches, is equal to the emitted frequency as it passes the observer and is lower than the emitted frequency as it recedes from the observer.

For waves that propagate in a medium, such as sound waves, the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source, motion of the observer, or motion of the medium. Each of these effects is analysed separately. For waves which do not require a medium, such as light or gravity in special relativity, only the relative difference in velocity between the observer and the source needs to be considered.

Etymology
From Wikipedia, the free encyclopedia

Etymology is the study of the history of words —(The history of these words date as far back as two minutes ago)  []) when they entered a language, from what source, and how their form and meaning have changed over time.

In languages with a long detailed history, etymology makes use of philology, the study of how words change from culture to culture over time. However, etymologists also apply the methods of comparative linguistics to reconstruct information about languages that are too old for any direct information (such as writing) to be known. By analyzing related languages with a technique known as the comparative method, linguists can make inferences, about their shared parent language and its vocabulary. In this way, word roots have been found which can be traced all the way back to the origin of, for instance, the Indo-European language family.

Even though etymological research originally grew from the philological tradition, nowadays much etymological research is done in language families where little or no early documentation is available, such as Uralic and Austronesian.

Filament Propagation


(Wiki)

In nonlinear optics, filament propagation is propagation of a beam of light through a medium without diffraction. This is possible because the Kerr effect causes an index of refraction change in the medium, resulting in self-focusing of the beam.

Filament propagation of laser pulses in the atmosphere was observed in 1994 by Gérard Mourou and his team at University of Michigan. The balance between the self-focusing refraction and self-attenuating diffraction by ionization and rarefaction of a laser beam of terawatt intensities, created by chirped pulse amplification, in the atmosphere creates "filaments" which act as waveguides for the beam thus preventing divergence. If a light filament drops below the intensity needed for this dynamic balance, called modulation instability, it can merge with another filament and continue propagating without broadening as with all earlier means of sending light. The filaments, having made a plasma, turn the narrowband laser pulse into a broadband pulse having a wholly new set of applications.

Filament propagation in a semiconductor medium can also be observed in large aperture vertical cavity surface emitting

Glycine  is the organic compound with the formula NH2CH2COOH. It is the smallest of the 20 amino acids commonly found in proteins, coded by codons GGU, GGC, GGA and GGG. Because it has specialized structural properties in protein architecture, this compact amino acid is often evolutionarily conserved. For example, cytochrome c, myoglobin, and hemoglobin all contain conserved glycines. Glycine is unique among the proteinogenic amino acids in that is not chiral. Most proteins contain only small quantities of glycine. A notable exception is collagen, which contains about 35% glycine. In its solid, i.e., crystallized, form, glycine is a free-flowing, sweet-tasting crystalline material.

Indian summer is a name given to a period of sunny, warm weather in autumn, not long before winter. Usually occurring after the first frost, Indian summer can be in September, October, or early November in the northern hemisphere, and March, April, or early May in the Southern hemisphere. It can persist for a few days or extend to a week or more. This term is not related to the summer season in India.

Jewel BOX (Open Stellar Cluster)





NGC 4755: A Jewel Box of Stars
Credit & Copyright: Michael Bessell (RSAA, ANU), MSO

Explanation: The great variety of star colors in this open cluster underlies its name: The Jewel Box. One of the bright central stars is a red supergiant, in contrast to the many blue stars that surround it. The cluster, also known as Kappa Crucis contains just over 100 stars, and is about 10 million years old. Open clusters are younger, contain few stars, and contain a much higher fraction of blue stars than do globular clusters. This Jewel Box lies about 7500 light-years away, so the light that we see today was emitted from the cluster before even the Great Pyramids in Egypt were built. The Jewel Box, pictured above, spans about 20 light-years, and can be seen with binoculars towards the southern constellation of Crux.
