Safran Patroller. The Patroller is a French medium-altitude long-endurance unmanned aerial vehicle developed and manufactured by Safran Electronics & Defense (formerly by SAGEM). The airframe is based on the Stemme ASP S15 motor glider.

The first flight was in June 2009 at Kemijarvi in Finland; it was shown at the 2009 Paris Air Show. The Patroller is a Medium-altitude long-endurance unmanned aerial vehicle (MALE) by the definition of the NATO.

It completed another series of flight tests in July 2010, which demonstrated it is capable of missions lasting 20–30 hours; it can carry a 250 kg payload (including 80 kg under each wing).
 The Patroller will carry out imaging and surveillance trials in southern France, detecting forest fires.

The Patroller uses the same ground control station as Sperwer II. A Ku-band datalink is used; range is limited to 200 km (line of sight).

Safran Electronics & Defense and Egyptian aircraft factory AOI have signed a collaboration agreement concerning the Patroller UAV. AOI-Aircraft Factory could handle final assembly of the drones and will develop a dedicated training center in Egypt to train staff for the operation and maintenance of the drone systems.

Statistical fluctuations. Statistical fluctuations are fluctuations in quantities derived from many identical random processes. They are fundamental and unavoidable. It can be proved that the relative fluctuations reduce as the square root of the number of identical processes.

Statistical fluctuations are responsible for many results of statistical mechanics and thermodynamics, including  phenomena such as shot noise in electronics.

Description
When a number of random processes occur, it can be shown that the outcomes fluctuate (vary in time) and that the fluctuations are inversely proportional to the square root of the number of processes. The average of fluctuations over a statistical ensemble is always zero as they are defined as deviations from the mean.

Measuring Fluctuations 
To characterize the intensity of fluctuations, several statistical measures are used. The Variance is the most common measure of fluctuation intensity. It's defined as the average of the squared deviations from the mean. The Root Mean Square (RMS) fluctuation: This is the square root of the variance and provides a measure of the typical magnitude of fluctuations.

Examples
As an example that will be familiar to all, if a fair coin is tossed many times and the number of heads and tails counted, the ratio of heads to tails will be very close to 1 (about as many heads as tails); but after only a few throws, outcomes with a significant excess of heads over tails or vice versa are common; if an experiment with a few throws is repeated over and over, the outcomes will fluctuate a lot.

An electric current so small that not many electrons are involved flowing through a p-n junction is susceptible to statistical fluctuations as the actual number of electrons per unit time (the current) will fluctuate; this produces detectable and unavoidable electrical noise known as shot noise.

Thermal lag. Thermal lag describes a body's temperature with respect to time as a result of its thermal mass. A body with high thermal mass (high heat capacity and low conductivity) will have a large thermal lag. 

 

where  is the thermal diffusivity of the material (m2s−1),  is the external angular frequency (s−1), and  is the thickness (m).

Examples

The slow night-time cooling of a home after its external brick wall has been heated by the sun is one example of thermal lag.  Thermal lag is the reason the high temperatures in summer continue to increase after the summer solstice (in this case, it is termed seasonal lag), and it is the reason a day's high temperature peaks in the afternoon instead of when the Sun is at its peak (12 noon).

Peter rehra. A , ()  is a type of locally-made jugaad vehicle used in rural Punjab and other Northern Indian states. It is, of course, not meant for high-performance, but for sheer economy, as it is easily able to carry twenty to twenty-five adults (plus their luggage), but mostly cannot move at more than 25 km/h. There has been instances when Punjab Police themselves used this to carry a whole Maruti 800 (which they could not drive out of court orders)

It is made by assembling parts. A diesel engine (mostly meant for pumping water) without its pumpset assembly is joined with a framework made of steel angles and wooden planks and completed with four movable wheels. The two front wheels are steerable (like in all vehicles) and the two rear ones are directly attached to the engine via a primitive gear assembly made from old SUV parts. 

Though it is not technically recognized by the Government as a legal vehicle, its use is quite common, mainly due to the high demand for public transport and lack of proper bus and train routes, especially to underdeveloped parts of the North Indian provinces.

The name originated from "Petter", a brand of small diesel engines imported to India in early 1960s.

It is also known as  ();  (), which means the male version of the Maruti 800 car by Maruti Suzuki partnership in India; or  (), after Sukhdev Singh Dhindsa, who was a former State Transport Minister of Punjab.

Bramhani Industries. Bramhani Industries Limited also known as Brahmani Steels and Bramhani Steels is an Indian iron and steel company promoted by Obulapuram Mining Company and G. Janardhana Reddy. The company is building a 1.7 metric tonnes per annum steel plant in Kadapa district of Andhra Pradesh. The company has announced plans to source state of the art steel equipment from China. The company has also proposed to build a 6 million metric ton steel plant in Bellary.  JSW steel is said to be in talks for partial ownership of OMC. Bramhani steels and Obulapuram are linked to illegal mining of Iron ore in Karnataka.

Political connections and resource allotment
Brahmani steels is reportedly in profit before producing any steel, owing to iron-ore sales from captive mines allotted by the Andhra Pradesh Government. Former Andhra Pradesh Chief minister Y. S. Rajasekhara Reddy allotted  of land to Brahmani steels at a rate of Rs 18,500 per acre in Kadapa. There is also an ongoing controversy in the allotment of water to Brahmani Steels in Kadapa at the expense of Rayalaseema Thermal Power Project (RTPS). Y. S. Jagan Mohan Reddy, the son of Y. S. Rajasekhara Reddy and the claimant of his political legacy, is reported to have a business interest in Brahmani.

William Dale Phillips. William Dale Phillips (October 10, 1925 – December 15, 1993) was an American chemist, nuclear magnetic resonance spectroscopist, federal science policy advisor and member of the National Academy of Sciences. He was born October 10, 1925, in Kansas City, Missouri and died in St. Louis, Missouri, on December 15, 1993.

Training
Phillips graduated from public high school and immediately entered the U.S. Navy V-12 program in 1943. He studied mechanical engineering at the University of Texas, was commissioned, and left active duty in 1946. Phillips completed a bachelor's degree in chemistry in 1948 at the University of Kansas and obtained a PhD in physical chemistry at MIT under the direction of Richard C. Lord studying the vibrational spectra of organic molecules.

Career
In 1951, Phillips joined DuPont Central Research. He held positions starting with research chemist, rising to research supervisor, manager and assistant and associate director. Phillips began to explore the nascent field of nuclear magnetic resonance (NMR). His initial interest was in molecular motion in organic systems. Together with Earl Muetterties, he also explored molecular dynamics in inorganic systems. DuPont's strength in organofluorine chemistry and cyanocarbon chemistry led to investigation of those systems. His work on paramagnetic molecules was the foundation of modern paramagnetic shift reagents and MRI imaging.

Phillips' interests then turned toward the biological. His particular interests were ferredoxins, and lysozyme. He also had a strong interest in the NMR and ESR of nucleic acids and other biological macromolecules.

To further his understanding of biochemistry, he took a DuPont Industrial Postdoctoral in 1962 to go to MIT in biochemistry. In 1973 he was on assignment from DuPont to ICI as liaison to their program to produce protein for animal feed from methane through fermentation microbiology. Retiring from DuPont Central Research in 1978, Phillips assumed the positions of chair and Charles Allen Thomas professor of chemistry at Washington University in St. Louis.

In 1984 he joined Mallinckrodt, Inc. as senior vice-president for research and development. He accepted a role on the Bush administration's Science Advisory Board. He chaired the National Critical Technologies Panel through the National Academy of Sciences. He served on the editorial boards of several scientific journals and on the boards of directors of Mallinckrodt, Sigma-Aldrich, the Missouri Corporation for Science and Technology, the St. Louis Science Center, the St. Louis Technology Center, and Celgene Corporation.

United States v. Riverside Bayview. United States v. Riverside Bayview, 474 U.S. 121 (1985), was a United States Supreme Court case challenging the scope of federal regulatory powers over waterways as pertaining to the definition of "waters of the United States" as written in the Clean Water Act of 1972. The Court ruled unanimously that the government does have the power to control intrastate wetlands as waters of the United States. This ruling was effectively revised in Rapanos v. United States (2006), in which the Court adopted a very narrow interpretation of "navigable waters."

Prior history
The case involves developer Riverside Bayview Homes Inc., which began placing fill materials on its property near the shores of Lake St. Clair, Michigan. The Army Corps of Engineers (Corps) filed suit in Federal District Court to prevent Riverside Bayview from filling its property without dredge and fill exception from the Corps as required under Clean Water Act §404.

The Eastern Michigan District Court held that the property was freshwater wetlands under the Corps's regulatory definition, which reads, "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions", and as such is subject to the Corps's permit authority because the lands were characterized by those conditions, and the property was adjacent to a body of navigable water. The Court of Appeals reversed, arguing that the Corps overstepped the definition of "waters of the United States", and took the view that the Corps's authority under the Clean Water Act and its implementing regulations must be narrowly construed to avoid a taking without just compensation in violation of the Fifth Amendment, and therefore Riverside Bayview was free to fill its property without obtaining a permit.

Decision
Writing the opinion for a unanimous Court, Justice Byron White ruled that neither the imposition of the permit requirement itself nor the denial of a permit would constitute taking, and that other legislation such as the Tucker Act exist to provide compensation for takings that may result. The Court ruled that the District Court did not err in its finding that the property falls within the Corps's regulatory definition of wetlands. White added that the Clean Water Act's language, policies, and history compel a holding that the Corps acted reasonably in its interpretation of its authorities over discharge material in wetlands.
