William G. Gregory. William George "Borneo" Gregory (born  May 14, 1957) is an American retired NASA astronaut and United States Air Force lieutenant colonel.

Early life and education 

Gregory was born in Lockport, New York, into an Albanian American family. He graduated from Lockport High School in 1975. Gregory is an Eagle Scout. He then attended the United States Air Force Academy, where he graduated with a degree in engineering sciences in 1979.  After this, he went to Columbia University to get a master's degree in engineering mechanics (1980), and Troy University to get another master's in management (1984). He is also a member of the USAF Academy Association of Graduates.

Career 

Between 1981 and 1986, Gregory served as an operational fighter pilot flying the D and F models of the F-111. In this capacity, he served as an instructor pilot at RAF Lakenheath, UK, and Cannon Air Force Base (AFB), New Mexico. He attended the USAF Test Pilot School in 1987. Between 1988 and 1990 Gregory served as a test pilot at Edwards AFB flying the F-4, A-7D, and all five models of the F-15. Having flown in excess of 40 types of aircraft, Gregory has accumulated over 5,000 hours of flight time.

Gregory retired as a captain at an air cargo carrier based in the U.S.

NASA career 

Selected by NASA in January 1990, Gregory became an astronaut in July 1991. Gregory's technical assignments included: Shuttle Avionics Integration Laboratory (SAIL); astronaut office representative for Landing/Rollout, T-38 Flying Safety; Kennedy Space Center Astronaut Support Personnel (ASP); spacecraft communicator (CAPCOM) in mission control; astronaut office representative for rendezvous and proximity operations; and Spacecraft Operations Branch Chief. He flew on STS-67 (1995) and has logged 400 hours in space. Gregory retired from the Air Force and left NASA in the Summer of 1999. He served as Vice President of Business Development for Qwaltec, Inc. in Tempe, Arizona, and was an airline pilot for a U.S. based cargo carrier.

Gregory served as the STS-67 pilot on the seven-person astronomical research mission aboard the Space Shuttle Endeavour. Launching from the Kennedy Space Center on March 2, 1995, and landing at Edwards AFB on March 18, 1995, the crew established a new mission duration record of 16 days, 15 hours, 8 minutes and 46 seconds, while completing 262 orbits and traveling nearly seven million miles. This second flight of the ASTRO telescope primary payload also included numerous secondary payloads.

Alizarine ink. Alizarine ink was created in 1855 by Professor Christian August Leonhardi of Dresden, Germany, by adding alizarin dye (derived from the root of the madder plant) to conventional iron gall ink.  This added an attractive coloration to the ink, which was quite popular until it was replaced by more modern chemical inks.

An 1881 recipe for Alizarine ink may be found in the Household Cyclopedia of General Information.

Stark's ink. Stark's ink is one of a number of types of homemade inks whose recipes were widely available in the 19th century.  People often made their own ink before 
commercially available ink was inexpensively and easily obtainable.
James Stark was a chemist during the 19th century who experimented with ink recipes for 23 years.  He tested 229 recipes for their durability on various kinds of paper to find the most stable iron gall ink recipe. He submitted his findings in 1855 to the Society of Arts in Edinburgh, Scotland. This recipe was the one he personally used.

Recipe 
This iron gall ink recipe is taken from the Household Cyclopedia of General Information, published in 1881.  It is not in common use now, though the preparation of inks with similar methods was common at one time.  
Recipe for  of ink:
, nut-galls
, sulfate of indigo 
, copperas
 of gum arabic
A few cloves

The addition of the sulfate of indigo renders the ink less stable on the page and prone to premature browning over time,  but less liable to mould in the inkwell. It is blue when first written with, but soon becomes an intense black.

The ink can be made without the sulfate of indigo, which will make it considerably less expensive yet more archival.  Without it, the ink will appear pale initially then quickly blacken as it dries.  The ink is very permanent and waterproof.

New Civil Engineer. New Civil Engineer is the monthly magazine for members of the Institution of Civil Engineers (ICE), the UK chartered body that oversees the practice of civil engineering in the UK. First published in May 1972, it is today published by Metropolis. Under its previous publisher, Ascential, who, as Emap, acquired the title and editorial control from the ICE in 1995, the ICE regularly discussed the magazine's content through an editorial advisory board and a supervisory board.

Available in print and online after the appropriate subscription has been taken out (it is free for members of the ICE), the magazine is aimed at professionals in the civil engineering industry. It contains industry news and analysis, letters from subscribers, a directory of companies, with listings arranged by companies’ areas of work, and an appointments section. It also occasionally has details of university courses and graduate positions.

In 2013 it had a net circulation of more than 50,000 per issue. Two years later, this had dropped to 42,805, of which some 39,000 related to copies distributed to ICE members.  Previously printed on a weekly basis the magazine switched to a monthly format in December 2015.
New Civil Engineer was a co-founder of the British Construction Industry Awards.

In  January 2017, Ascential announced its intention to sell 13 titles including New Civil Engineer; the 13 "heritage titles" were to be "hived off into a separate business while buyers are sought." The brands were purchased by Metropolis International Ltd (owner of the Property Week title since 2013) in a £23.5m cash deal, announced on 1 June 2017.

Jacqueline Whitelaw was the magazine's deputy editor from 1998 to 2009.

Mitsuru Matsui. is a Japanese cryptographer and senior researcher for Mitsubishi Electric Company.

Career
While researching error-correcting codes in 1990, Matsui was inspired by Eli Biham and Adi Shamir's differential cryptanalysis, and discovered the technique of linear cryptanalysis, published in 1993. Differential and linear cryptanalysis are the two major general techniques known for the cryptanalysis of block ciphers.

The following year, Matsui was the first to publicly report an experimental cryptanalysis of DES, using the computing power of twelve workstations over a period of fifty days.

He is also the author of the MISTY-1 and MISTY-2 block ciphers, and contributed to the design of Camellia and KASUMI.

For his achievements, Matsui got the 2012 RSA Conference Award for Excellence in Mathematics.

DAR 10. The DAR 10 (ДАР 10) was a Bulgarian light bomber and reconnaissance aircraft. DAR-10 was designed for horizontal and dive bombing, reconnaissance, and ground attack.

Design and development
The DAR 10 was designed by Zvetan Lazarov in 1938 in the DAR (Darzhavna Aeroplanna Rabotilnitsa, meaning literally 'State Airplane Workshop') factory in Bozhurishte, near the capital Sofia.

The DAR 10 was a single-engine two-seat (pilot and gunner) low-wing cantilever monoplane aircraft of conventional layout.  Its two seats were in tandem under enclosed glazing.  Its tailwheel undercarriage was fixed, and the mainwheels were spatted.  The wings had a wooden structure, covered with plywood.  Flaps were not used.

The fuselage was comparatively wide and deep, to accommodate the nose-mounted radial engine.  It was constructed of steel-tube framework and wood formers, covered with fabric.

Three-bladed steel propellers were used.

Two prototypes were built, powered by different engines:
DAR 10A Bekas (Bulgarian: "snipe"), powered by an Alfa Romeo 128 R.C.21 nine-cylinder radial engine rated at 950 hp (709 kW).  This was the first DAR 10 to fly, on 2 July 1941. It was designed to carry four machine guns (two fixed forward-firing and two in rear gunner position).  It could carry five 100-kg bombs, mounted under the wings.  There was also the possibility of a fixed 20 mm forward-firing cannon installation in the forward fuselage.

This aircraft crashed in October 1942. In spite of good flight reviews, the type was not chosen for production.  The high-wing KB-11 Fazan was selected for production instead.

DAR 10F (the "F" to indicate its Fiat engine), powered by a Fiat A 74 R.C.38 14-cylinder radial engine rated at 870 hp (649 kW).  This aircraft first flew in March 1945. It was slightly heavier and longer than the DAR-10A.  Its top speed was 454 km/h (282 mph). Thanks to a stronger construction and dive brakes, it could serve also as a dive bomber. It could be equipped with two fixed fuselage-mounted 20 mm cannon firing forward, two fixed wing-mounted machine guns, and two machine guns for the gunner. It could carry one 500 kg (1,100 lb) bomb or one 250 kg (551 lb) and four 100 kg (110 lb). The bombs were mounted under the fuselage and wings.

The DAR-10 was not selected for production.  Some sources suggest that it was passed over in favor of the German Junkers Ju 87 Stuka dive bomber, while the improved DAR-10F was not selected as World War II had ended and Bulgaria had access to ample supplies of modern Soviet aircraft such as the Ilyushin Il-2 and Il-10.

Network security policy. A network security policy (NSP) is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security/ network security environment. The document itself is usually several pages long and written by a committee. 

A security policy is a complex document, meant to govern data access, web-browsing habits, use of passwords, encryption, email attachments and more. It specifies these rules for individuals or groups of individuals throughout the company. The policies could be expressed as a set of instructions that understood by special purpose network hardware dedicated for securing the network.

Security policy should keep the malicious users out, and also exert control over potential risky users within an organization. 

Understanding what information and services are available and to which users, as well as what the potential is for damage and whether any protection is already in place to prevent misuse are important when writing a network security policy.  In addition, the security policy should dictate a hierarchy of access permissions, granting users access only to what is necessary for the completion of their work. The National Institute of Standards and Technology provides an example security-policy guideline.

Hydrobromic acid. Hydrobromic acid is an aqueous solution of hydrogen bromide. It is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at  and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid is one of the strongest mineral acids known.

Uses
Hydrobromic acid is mainly used for the production of inorganic bromides, especially the bromides of zinc, calcium, and sodium.  It is a useful reagent for generating organobromine compounds.  Certain ethers are cleaved with HBr. It also catalyzes alkylation reactions and the extraction of certain ores. Industrially significant organic compounds prepared from hydrobromic acid include allyl bromide, tetrabromobis(phenol), and bromoacetic acid.  HBr almost uniquely participates in anti-Markovnikov hydrohalogenation of alkenes.  The resulting 1-bromoalkanes are versatile alkylating agents, giving rise to fatty amines and quaternary ammonium salts.

Synthesis
Hydrobromic acid can be prepared in the laboratory via the reaction of Br2, SO2, and water.

Br2 + SO2 + 2 H2O -> H2SO4 + 2 HBr

More typically laboratory preparations involve the production of anhydrous HBr, which is then dissolved in water.

Hydrobromic acid has commonly been prepared industrially by reacting bromine with either sulfur or phosphorus and water.  However, it can also be produced electrolytically. It can also be prepared by treating bromides with non-oxidising acids like phosphoric or acetic acids.

Alternatively the acid can be prepared with dilute (5.8M) sulfuric acid and potassium bromide:

H2SO4 + KBr -> KHSO4 + HBr

Using more concentrated sulfuric acid or allowing the reaction solution to exceed 75 °C further oxidizes HBr to elemental bromine. The acid is further purified by filtering out the KHSO4 and by distilling off the water until the solution reaches an azeotrope (124.3 °C). The yield is approximately 85%.

Hydrobromic acid is available commercially in various concentrations and purities.

DEC Systems Research Center. The Systems Research Center (SRC) was a research laboratory created by Digital Equipment Corporation (DEC) in 1984, in Palo Alto, California.  

DEC SRC was founded by a group of computer scientists, led by Robert Taylor, who left the Computer Science Laboratory (CSL) of Xerox PARC after an internal power struggle. SRC survived the takeover of DEC by Compaq in 1998. It was renamed to "Compaq Systems Research Center". When Compaq was acquired by Hewlett-Packard in 2002, SRC was merged with other HP corporate research labs and relocated there.

After Taylor's retirement, the lab was directed by Roy Levin and then by Lyle Ramshaw.

Some of the critical developments made at SRC include the Modula-3 programming language; the snoopy cache, used in the first multiprocessor workstation, the Firefly, built from MicroVAX 78032 microprocessors; the first multi-threaded Unix system, Taos; the first user interface editor; early networked window systems, Trestle.  AltaVista was jointly developed by researchers from DEC's Network Systems Laboratory, Western Research Laboratory and Systems Research Center. Among the researchers at SRC, there are Butler Lampson, Chuck Thacker, and Leslie Lamport, all recipients of the ACM A.M. Turing Award.

A later inhabitant of this building is A9.com, a research part of Amazon.com.
