F♯ A♯ ∞

F♯ A♯ ∞ (pronounced "F-sharp, A-sharp, Infinity") is the debut album of the Canadian post-rock band Godspeed You! Black Emperor. It was released twice, first in 1997 by Constellation Records and then again on 8 June 1998, by Kranky as an expanded edition that ran for 63:27. The album is devoid of traditional lyrics and mostly instrumental, featuring lengthy songs segmented into movements and wide dynamics.

The album was recorded at the Hotel2Tango in the Mile End of Montreal. It was initially released in very limited quantities, and was mainly distributed through live performances and advertised by word of mouth.

Recording

In 1995, Mauro Pezzente moved into a loft with his then-girlfriend in the Mile End of Montreal. Pezzente used the flat as a performance venue, dubbing it the Gallery Quiva. Around 1996, fumes from the mechanic's garage below the loft forced them to vacate it. Shortly after their departure, Efrim Menuck moved into the space and established Hotel2Tango, serving both as a recording studio and practice space. There, in 1997, the original recording of F♯ A♯ ∞ took place. By this time, the band had reached an unwieldy 15 members. In preparation of the album, they trimmed their numbers to ten.

F8A1

Factor VIII intron 22 protein is a protein that in humans is encoded by the F8A1 gene.

This gene is contained entirely within intron 22 of the factor VIII gene; spans less than 2 kb, and is transcribed in the direction opposite of factor VIII. A portion of intron 22 (int22h), containing F8A, is repeated twice extragenically closer to the Xq telomere. Although its function is unknown, the observation that this gene is conserved in the mouse implies it has some function. Unlike factor VIII, this gene is transcribed abundantly in a wide variety of cell types.

United States military aircraft designation systems

The United States Military Aircraft Designation System was first designed in 1919 when the US Army's Aeronautical Division became the United States Army Air Service. Before this aircraft were put into service under their manufacturers' designations.

History

United States Army Air Service 1919 to 1924

During this period Type Designations used by the United States Army Air Service were allotted, using two or three letters, which were an abbreviation of the aircraft's purpose. Examples include GA for Ground Attack aircraft; NO for Night Observation aircraft and NBS for Night Bombardment, Short Distance aircraft.

Army aviation 1924 to 1962

From 1924 to 1947 the Air Service, United States Army Air Corps, United States Army Air Forces and United States Air Force used a designation system based on mission category, with each model in a category numbered sequentially. In 1947, the designation system was extensively overhauled, with several categories being dispensed with, and others renamed For instance, the Lockheed P-80 Shooting Star (Pursuit) was redesignated as F-80 (Fighter), while the A-26 medium bomber/attack aircraft was redesignated as the B-26, reusing the designation, the Martin B-26 having retired in the meantime.

Lockheed Martin F-35 Lightning II

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters undergoing final development and testing by the United States. The fifth generation combat aircraft is designed to perform ground attack, aerial reconnaissance, and air defense missions. The F-35 has three main models: the F-35A conventional takeoff and landing (CTOL) variant, the F-35B short take-off and vertical-landing (STOVL) variant, and the F-35C carrier-based Catapult Assisted Take-Off But Arrested Recovery (CATOBAR) variant. On 31 July 2015, the first squadron was declared ready for deployment after intensive testing by the United States.

The F-35 is descended from the X-35, which was the winning design of the Joint Strike Fighter (JSF) program. It is being designed and built by an aerospace industry team led by Lockheed Martin. Other major F-35 industry partners include Northrop Grumman, Pratt & Whitney and BAE Systems. The F-35 took its first flight on 15 December 2006. The United States plans to buy 2,457 aircraft. The F-35 variants are intended to provide the bulk of the manned tactical airpower of the U.S. Air Force, Navy, Marine Corps over the coming decades. Deliveries of the F-35 for the U.S. military are scheduled to be completed in 2037.

HP 20b

The HP 20b Business Consultant (F2219A) is a financial calculator published in 2008 by Hewlett-Packard. Its function is similar to HP 10bII and includes scientific and statistical functions.

Hardware Specification

The HP 20b uses a 2 lines display with the first line an 8 character scrolling display and 11 indicators and the second line for 12+3 digit display. It also uses 2 CR2032 batteries, an Atmel AT91SAM7L128 30 MHz processor. The processor's serial interface is accessible from under the battery cover to allow the firmware to be updated using a special cable from HP.

Functions

The HP 20b contains functions similar to the HP 10bII, with financial functions including: TVM, IRR, NPV, NUS ("Net Uniform Series"), amortization, depreciation, bonds, yield and accrued interest, interest conversion, list-based cashflow analysis, cashflows, break-even analysis.

Math/Statistics functions include: list-base, 1 and 2 variable statistics, mean, standard deviation, population deviation, standard error, forecasting, correlations and covariance, +, -, X, ÷, %, 1/x, +/-, scientific notation, n!, combinations, permutations, rounding, random numbers, LOG, LN, 10x, PL, square root, trigonometry, probability.
