Boeing XP-8
The Boeing XP-8 (Boeing Model 66) was a prototype American biplane fighter of the 1920s, notable for its unusual design incorporating the engine radiator into the lower wing.Jones 1975, p. 34–35. Design and development Boeing developed the prototype in 1926 as a private venture, with the goal of winning the Army Air Corps competition announced in 1925. Designated by Boeing as its Model 66, the airframe was basically a PW-9 with an experimental 600 hp Packard 2A-1500 engine. In order to streamline around the engine, the radiator was moved back so that the opening coincided with the front edge of the lower wing, resulting in an unusually narrow profile around the engine. Testing Army testing of the aircraft began in January 1928, and it handled well, but performance was lacking, achieving only a maximum speed of 173.2 mph. Even so, the prototype continued in Air Corps service until June 1929, after which it was scrapped. The airframe design lived on in the Navy's ...

Heckler & Koch USP
The USP (''Universelle Selbstladepistole'' or "universal self-loading pistol") is a semi-automatic pistol developed in Germany by Heckler & Koch GmbH (H&K) as a replacement for the P7 series of handguns. History Design work on a new family of pistols commenced in September 1989, focused primarily on the United States commercial and law enforcement markets. USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM), which would later result in the Mk 23 Mod 0. The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993 with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9 (using the 9×19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP).

Allotropes Of Phosphorus
Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and atomic phosphorus. White phosphorus White phosphorus, yellow phosphorus or simply tetraphosphorus () exists as molecules made up of four atoms in a tetrahedral structure. The tetrahedral arrangement results in ring strain and instability. The molecule is described as consisting of six single P–P bonds. Two crystalline forms are known. The α form is defined as the standard state of the element, but is actually metastable under standard conditions. It has a body-centered cubic crystal structure, and transforms reversibly into the β form at 195.2 K. The β form is believed to have a hexagonal crystal structure. White phosphorus is a translucent waxy solid that quickly becomes yellow when exposed to light. For this reason it is also called yellow phosphorus. It glows greenish in t ...

P8 Group
The P8 Group brings together senior leaders from some of the world's largest public pension funds to develop actions relating to global issues and particularly climate change. It is an initiative of the Cambridge Programme for Sustainability Leadership (CPSL) and HRH Prince of Wales’s Business and Environment Programme (BEP) supported by the Environmental Capital Group (ECG) and the Nand & Jeet Khemka Foundation. The P8 Group involves ten leading global pension funds and sovereign wealth funds, including representatives from Europe, Asia, Australasia and North America. They represent over $3 trillion of investment capital and as pension funds have an inherently long term focus. In November 2007 the first P8 Summit was held. This brought together leaders from eight of the world's largest public pension funds with key experts including Vice President Al Gore and HRH Prince of Wales. The P8 Summit was a critical start in getting pension funds to lead in the move toward a low-car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Period 8
An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven. , the element with the highest atomic number known is oganesson (''Z'' = 118), which completes the seventh period (row) in the periodic table. All elements in the eighth period and beyond thus remain purely hypothetical. Elements beyond 118 will be placed in additional periods when discovered, laid out (as with the existing periods) to illustrate periodically recurring trends in the properties of the elements concerned. Any additional periods are expected to contain a larger number of elements than the seventh period, as they are calculated to have an additional so-called ''g-block'', containing at least 18 elements with partially filled g- orbitals in each period. An ''eight-period table'' containing this block was suggested by Glenn T. Seaborg in 1969. The first element of the g-block may have atomic number 121, and thus would have the systematic name ...

Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic freq ...

Octave
In music, an octave ( la, octavus: eighth) or perfect octave (sometimes called the diapason) is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music," the use of which is "common in most musical systems." The interval between the first and second harmonics of the harmonic series is an octave. In Western music notation, notes separated by an octave (or multiple octaves) have the same name and are of the same pitch class. To emphasize that it is one of the perfect intervals (including unison, perfect fourth, and perfect fifth), the octave is designated P8. Other interval qualities are also possible, though rare. The octave above or below an indicated note is sometimes abbreviated ''8a'' or ''8va'' ( it, all'ottava), ''8va bassa'' ( it, all'ottava bassa, sometimes also ''8vb''), or simply ''8'' for the octave in the direction indicated by placing ...

Luger P08
The Pistole Parabellum—or Parabellum-Pistole (Pistol Parabellum), commonly known as just Luger or Luger P08 is a toggle-locked recoil-operated semi-automatic pistol. The Luger was produced in several models and by several nations from 1898 to 1949. The design was first patented by Georg Luger. It was meant to be an improvement of the Borchardt C-93 pistol, and was initially produced as the ''Parabellum Automatic Pistol, Borchardt-Luger System'' by the German arms manufacturer Deutsche Waffen und Munitionsfabriken (DWM).Datig, Fred A., ''The Luger Pistol'', Gun Digest, 1957 ed., Chicago Illinois: Edward Keogh Co. Inc. (1956) pp. 164-165 The first production model was known as the ''Modell 1900 Parabellum''. It was followed by the "Marinepistole 1904" for the Imperial German Navy. The Luger was officially adopted by the Swiss military in 1900, the Imperial German Navy in 1906 and the German Army in 1908. The Luger was the standard service pistol of Switzerland, Portugal, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Core (microarchitecture)
The Intel Core microarchitecture (provisionally referred to as Next Generation Micro-architecture, and developed as Merom) is a multi-core processor microarchitecture launched by Intel in mid-2006. It is a major evolution over the Yonah, the previous iteration of the P6 microarchitecture series which started in 1995 with Pentium Pro. It also replaced the NetBurst microarchitecture, which suffered from high power consumption and heat intensity due to an inefficient pipeline designed for high clock rate. In early 2004 the new version of NetBurst (Prescott) needed very high power to reach the clocks it needed for competitive performance, making it unsuitable for the shift to dual/multi-core CPUs. On May 7, 2004 Intel confirmed the cancellation of the next NetBurst. Intel had been developing Merom, the 64-bit evolution of the Pentium M, since 2001, and decided to expand it to all market segments, replacing NetBurst in desktop computers and servers. It inherited from Pentium M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
