Microphotonics is a branch of technology that deals with directing light on a microscopic scale and is used in optical networking. It refers to the branch of technology that deals with wafer-level integrated devices and systems that emit, transmit and process light along with other forms of radiant energy with photon as the quantum unit. Microphotonics employs at least two different materials with a large differential index of refraction to squeeze the light down to a small size. Speaking all of microphotonics relies on Fresnel reflection to guide the light. If the photons reside in the higher index material, the confinement is due to total internal reflection. If the confinement is due many distributed Fresnel reflections, the device is termed a photonic crystal. There are many different types of geometries used in microphotonics including optical waveguides, optical microcavities, Arrayed waveguide gratings. Photonic crystals are non-conducting materials that reflect various wavelengths of light perfectly.
Such a crystal can be referred to as a perfect mirror. Other devices employed in microphotonics include photonic wire waveguides; these tools are used to "mold the flow of light", a famous phrase for describing the goal of microphotonics. The crystals serve as structures that allow the manipulation and control of light in one, two, or three dimensions of space. An optical microdisk, optical microtoroid, or optical microsphere uses internal reflection in a circular geometry to hold on to the photons; this type of circularly symmetric optical resonance is called a Whispering gallery mode, after Lord Rayleigh coined the term. Microphotonics has biological applications and these can be demonstrated in the case of the "biophotonic chips", which are developed to increase efficiency in terms of "photonic yield" or the collected luminescent signal emitted by fluorescent markers used in biological chips. Microphotonics technology is being developed to replace electronics devices and bio-compatible intracellular devices.
For instance, the long-standing goal of an all-optical router would eliminate electronic bottlenecks, speeding up the network. Perfect mirrors are being developed for use in fiber optic cables. Photonics
Tyrophagus putrescentiae is a cosmopolitan mite species. Together with the related species T. longior, it is referred to as the mould mite or the cheese mite. The name translates from Greek to something like "putrid cheese eater." In the wild, T. putrescentiae occurs throughout the world in a wide range of habitats, including "grasslands, old hay and the nest of bees and ducks". Under ideal conditions, with temperatures above 30 °C and humidity above 85%, it can complete its life cycle in under three weeks, it is a common pest of stored products those with a high protein and fat content. It feeds on the fungi that grow on the foodstuffs, can become a pest of mycology laboratories. Tyrophagus putrescentiae has been identified as the cause of human disease in different regions, it has been found to cause copra itch among people who handle copra in the tropics and respiratory allergies among people handling raw hams in Italy, dermatitis in an Austrian butcher's shop. Tyrophagus putrescentiae was first described by Franz von Paula Schrank in 1781, under the name Acarus putrescentiae.
This original description covered both a mite and a springtail, collected from garden soil, flower pots and rotting leaves at an undisclosed location in the Austrian Empire, provided too little information for the mite to be confidently assigned to any family. In 1906, Anthonie Cornelis Oudemans treated A. putrescentiae as a species "indeterminabilia", but designated it as the type species of his new subgenus Tyrophagus. The identity of Schrank's species was not fixed until Phyllis Robertson revised the genus Tyrophagus in 1959, designated a neotype of T. putrescentiae from Oudemans' collections. The International Commission on Zoological Nomenclature approved an application to place Tyrophagus putrescentiae on its official list of approved names. In 2007, it was discovered that Robertson's concept of the species in fact covered animals belonging to two distinct species, that the Tyrophagus putrescentiae had been chosen from the much rarer species. A petition has been made to the Commission to stabilise usage by applying the name T. putrescentiae to the common species.
The Ghana women's national football team represents Ghana in women's association football and is administered by the Ghana Football Association. Football has been played in the country since 1903, organised by the national association since 8 September 1957. In 1991, the Black Queens were "hurriedly assembled" ahead of their first official match during the qualifying rounds for the 1991 FIFA Women's World Cup, a 5–1 defeat against Nigeria on 16 February 1991 — the first women's association football match on African ground; the team's largest victories came on 29 March 1998 and 11 July 2004 when they defeated Guinea by 11–0 and 13–0, respectively. Their worst loss is 11–0 against Germany on 22 July 2016. Between 1991 and 2018, Ghana played 120 international matches, resulting in 66 victories, 22 draws and 32 defeats; as of September 2018, the Black Queens are ranked 47th in the FIFA Women's World Rankings
Wilbur Elementary School is a former elementary school located in Somerset, United States. The school included kindergarten through fifth grade, it was involved with a state test scam. In June 2014, the school closed permanently; the Wilbur School had the highest fifth grade mathematics scores of any elementary school in the state on the Massachusetts Comprehensive Assessment System test, according to results that were released the week of September 13, 2010. Of the 28 fifth graders at Wilbur School during the last school year, 79 percent scored in the advanced category of the MCAS test, while the other 21 percent scored in the proficient category. None of the fifth graders at the Wilbur School scored in the needs improvement or failing categories. "We are delighted and surprised that we were ranked first in the state," Wilbur School Principal Joan DeAngelis said. The scores are based on tests that were taken during the previous school year, so the students who received the high marks were, at the time sixth graders at Somerset Middle School.
Somerset School Superintendent Richard Medeiros said the Wilbur School was one of the few schools in the state that did not have one grade five student fail the mathematics section of the MCAS test or score in the needs improvement category. He said those types of scores are unheard of on the test and said one of the goals of the federal No Child Left Behind Act is to have all students scoring in the proficient and advanced levels of the MCAS test by 2014. "Many educators would say, not possible, but they met that," Mr. Medeiros said of the students at the Wilbur School; this sparked controversy. For some parents who had watched their children struggle all year with math assignments, the stellar results didn’t add up; the year before one in three fifth-graders had failed to reach proficiency. This time around, none failed to reach that mark. State education officials investigated whether the scores were legitimate after receiving complaints from suspicious parents. One parent told officials that her child received an “advanced’’ score on the MCAS after receiving mediocre marks in her math class.
On April 11, 2011, The Herald News, a Fall River-based newspaper, reported that all 74 test scores were voided. They were invalidated after a state investigation which showed a high rate of wrong answers changed to correct ones; the investigation found a decidedly higher number of erasures than the state average on answer booklets, with a “vast majority” of answers changed from incorrect responses to correct ones. The state found a disturbing pattern of answers to open-response questions in which students’ original responses were erased and replaced with correct answers that were not supported by the students’ original computations and logic. DeAngelis resigned from Somerset Public Schools in August 2012. In January 2014, the Somerset School Committee voted 4-1 to close Wilbur School effective for the 2014-2015 school year
