Derek John de Solla Price was a physicist, historian of science, information scientist, credited as the father of scientometrics. Price was born in Leyton, England, to Philip Price, a tailor, Fanny de Solla, a singer, he began work in 1938 as an assistant in a physics laboratory at the South West Essex Technical College, before studying Physics and Mathematics at the University of London, where he received a Bachelor of Science in 1942. He obtained a Doctor of Philosophy in experimental physics from the University of London in 1946. In 1948 Price worked as a teacher of applied mathematics at Raffles College, to become part of the National University of Singapore, it was there that he formulated his theory on the exponential growth of science, an idea that occurred to him when he noticed the characteristic logarithmic curve of the Philosophical Transactions of the Royal Society between 1665 and 1850, which he had stacked against his wall at home while Raffles College had its library built. After three years, Price returned to England to work on a second Ph.
D. in the history of science, this time at the University of Cambridge. During his Ph. D. studies, he accidentally discovered Equatorie of the Planetis, a Peterhouse manuscript in Cambridge University Library, written in Middle English, which he attributed to Geoffrey Chaucer. It is now attributed to a St Albans monk called John Westwyk. Around 1950, Price adopted his mother's Sephardic name, "de Solla", as a middle name, he was a "British Atheist... from a rather well-known Sephardic Jewish family", although his Danish wife, had been christened as a Lutheran, he did not, according to their son Mark, regard their marriage as "mixed", because they were both atheists. After obtaining his second doctorate, Price moved to the United States, where he served as a consultant to the Smithsonian Institution, as a fellow at the Institute for Advanced Study in Princeton, New Jersey, his next post was at Yale University, where he worked until his death, serving as the Avalon Professor of the History of Science, as chair of a new department that encompassed the histories of science and medicine.
In 1984, Price received, the ASIS Research Award for outstanding contributions in the field of information science. Since 1984, the Derek de Solla Price Memorial Medal is awarded by the International Society for Scientometrics and Informetrics to scientists with outstanding contributions to the fields of quantitative studies of science. Price's major scientific contributions include: Price's square root law or Price's law pertains to the relationship between the literature on a subject and the number of authors in the subject area, stating that half of the publications come from the square root of all contributors. Thus, if 100 papers are written by 25 authors, five authors will have contributed 50 papers. Price's law has been likened to the Matthew Principle, it can be modeled using a L-shaped graph, with number of people on the Y-axis, productivity or resources on the X-axis.

Fedele de Giorgis was an Italian general of the Kingdom of Italy. He was born in Metropolitan City of Turin, Piedmont, he was a veteran of World War I. From 1938 to 1940 he obtained the command of the 3rd Alpine division "Julia" stationed in Albania, he was promoted to major general on January 1, 1940 and became commander of the 55th Infantry Division Savona during World War II. He was head of the delegation of the Italian armistice commission with France in Syria, it was during this period that he proposed the idea of the Italian foreign legion, an idea, welcomed by the Italian general staff, which gathered in it all the anti-allied volunteers willing to fight with the Axis countries. On 17 January 1942 he was taken prisoner by them. From May 16, 1947 until May 24, 1950 was the commander in chief of the'Arma dei Carabinieri', he supported the foundation of ONAOMAC. He was a recipient of the Bronze Medal of Military Valor, he was one of the nine Italian recipients of the Knight's Cross of the Iron Cross, receiving his award from Nazi Germany on January 9, 1942.

The Mark of the Hawk is a 1957 drama film, directed by Michael Audley with a screenplay by Lloyd Young and H. Kenn Carmichael; the film stars Sidney Poitier. Obam, brother of an indigenous resistance leader in British colonial Africa, returns to his troubled homeland after some years abroad, seeking a political post. However, domestic tensions have divided the country into two hostile camps, with many natives demanding the return of their ancestral lands - now farmed by European settlers. Britain and the local white administration are determined not to release their stranglehold, his motives are questioned by his own people, but with the assistance of an insightful spouse and sympathetic missionary Bruce Craig, this unlikely newcomer to African nationalism fights to make a meaningful difference before the situation deteriorates further. Eartha Kitt as Renee. Studios, England Although Sidney Poitier is listed fourth, below John McIntire, in the opening credits, he receives second billing in the closing credits.
The opening credits include the following written statement: "The producers wish to acknowledge the cooperation extended to them by the Cinema Corporation of Nigeria." The end credits note that the film was "made at Associated British Elstree Studios, England." According to a December 1957 Film Daily item, The Mark of the Hawk was shot on location in Nigeria, after which Universal bought the distribution rights.

Deaconal University College is a folk high school and university college in Højbjerg. The Deaconal University College offers a 4-year bachelor's degree programme in diaconia and social pedagogy; the education produces deaconal personnel, which in a modern Danish context are church-related social workers. Deacons educated in Denmark are lay people. Graduates from the Deaconal University College get jobs in NGOs, such as the YMCA and YWCA social programmes, as well as state-based institutions and projects; the Deaconal University College is based on the values and creed of the Danish National Church, episcopal evangelical Lutheran. However and dialogue is valued with regard to students of other denominations who attend the school; the school runs a 3-month course for international students. The course aims to equip students be able to initiate and evaluate development projects and to raise awareness of social and development issues in church and society; the school dates from the 1920s and has evolved from educating deacons for the nursing sector to providing training in different fields of social work——taking care of people with drug addictions, the mentally challenged and adults with special physical and/or mental needs.

Radiofrequency coils are the receivers, sometimes the transmitters, of radiofrequency signals in equipment used in magnetic resonance imaging. The MR signal in MRI is produced by the process of resonance, the result of radiofrequency coils, they consist of two electromagnetic coils, the transmitter and receiver, which generate the field and receive the resulting signal. Atomic nuclei of interest in MRI studies have their own resonant frequencies, in the radiofrequency portion of the electromagnetic spectrum. Although the electromagnetic fields produced by the transmitting coil are in the RF range of tens of megahertz at powers exceeding the highest powers used by amateur radio, there is little RF interference produced by the MRI machine; the reason for this is that the MRI is a poor radio transmitter, is without an antenna. The RF frequency electromagnetic field produced in the "transmitting coil" is a magnetic near-field with little associated changing electric field component. Thus, the high-powered electromagnetic field produced in the MRI transmitter coil does not produce much electromagnetic radiation at its RF frequency, the RF power is confined to the coil space and not radiated as "radio waves."
Thus, the transmitting coil is a good EM near-field generator at radio frequency, but a poor EM radiation transmitter at radio frequency. The receiver coil picks up the oscillations at RF frequencies produced by precession of the magnetic moment of nuclei inside the subject; the signal acquired by the coil is thus an induced emf, is not the result of picking up radio waves. This is a common misconception, has propagated through the literature. MRI scanners are situated in metal mesh lined rooms which act as Faraday cages.) RF coils for MRI can be grouped into two different classes: surface coils. Volume coils are designed to provide a homogeneous RF excitation across a large volume. Most clinical MRI scanners include a built in volume coil to perform whole-body imaging, smaller volume coils have been constructed for the head and other extremities. Common designs for volume coils include Birdcage Coils, TEM Coils, Saddle Coils; these coils require a great deal of RF power because of their size, so they are driven in quadrature in order to reduce by two the RF power requirements.
The condition to attain a high RF magnetic field homogeneity is to approximate spatial cosine current distribution in radiofrequency coil. The RF homogeneity of volume coils is desirable for transmission, but is less ideal when the region of interest is small; the large field of view of volume coils means that they receive noise from the whole body, not just the region of interest. Surface coils are designed to provide a high RF sensitivity over a small region of interest; these coils are single or multi-turn loops which are placed directly over the anatomy of interest. The size of these coils can be optimized for the specific region of interest. Surface coils make poor transmission coils because they have poor RF homogeneity over their region of interest, their small field of view makes them ideal as receivers, as they only detect noise from the region of interest.

Bring Your Nothing is the eighth studio album by the Contemporary worship duo Shane & Shane. The album was released on May 2013 by Fair Trade Services record label. Bring Your Nothing has received positive ratings and reviews from the Christian music critics. At Alpha Omega News, Ken Wiegman wrote that he "was impressed with what seems like a new direction instrumentally for the songwriting duo". Daniel Edgeman of Christian Music Review called the release a "great blend of message and music", "very simple and powerful", found that "Shane and Shane bring way more than nothing!" Writing for Christian Music Zine, Joshua Andre felt that the album "does not disappoint" and noted that the release "will change you life" because it is a "gem". Tony Cummings of Cross Rhythms found the "album well worth tracking down." Louder Than the Music's Jono Davies stated that the release "sounds powerful and rich in tone, yet not over produced." Kevin Davies of New Release Tuesday called this "one of the most worshipful and introspective albums".
At Worship Leader, Barry Westman told that "Shane and Shane, along with 5 other friends, recorded these tunes all in one room. This unique recording method resulted in a organic, cohesive feel to the album."At The Christian Manifesto, Calvin E'Jon Moore noted that the duo "has presented listeners with a decent batch of new songs" that he contended "isn't as spectacular or moving as the songs on Clean or Psalms". Jonathan Andre of Indie Vision Music called the album "thought-provoking and encouraging". At Jesus Freak Hideout, Alex "Tincan" Caldwell alluded to how the album's "ping-ponging sounds and styles" makes the release feel "jarring and confusing." Bert Gangl of Jesus Freak Hideout stated that the album "offers just enough top-drawer material to keep the most-devoted members of the existing fan base engaged." At CCM Magazine, Grace S. Aspinwall felt that "Shane and Shane bring more than nothing on this release, although the vast array of styles lends an identity crisis of sorts." Derek Walker of The Phantom Tollbooth said that "this will doubtless please their longtime fans and win them respect from others."
