China Flying Dragon Aviation. China Flying Dragon Aviation () is an airline based in Harbin, Heilongjiang, China. It operates short-haul passenger and cargo charter flights, as well as maritime surveillance, aerial photography and forestry protection services. Its main base is Harbin Taiping International Airport.

History 
The airline was established and started operations in 1981. It is owned in a joint venture by the Harbin Aircraft Manufacturing Corporation and the former Ministry of Geology and Mineral Resources, now part of the Ministry of Land and Resources.

During the rescue and post-operations of the 2008 Sichuan earthquake, heavy equipment needed to be transported to deal with the dangerous formation of quake-lakes located in extremely difficult terrain, particularly at Tangjiashan mountain, which was accessible only by foot or air. A China Flying Dragon Special Aviation Company's Mi-26T heavy lift helicopter was used to bring heavy earth-moving tractors, fuel, and equipment to the affected location to create a sluice to relieve the dangerous quake-lake.

NetWare Core Protocol. The NetWare Core Protocol (NCP) is a network protocol used in some products from Novell, Inc. It is usually associated with the client-server operating system Novell NetWare which originally supported primarily MS-DOS client stations, but later support for other platforms such as Microsoft Windows, the classic Mac OS, Linux, Windows NT, Mac OS X, and various flavors of Unix was added.

The NCP is used to access file, print, directory, clock synchronization, messaging, remote command execution and other network service functions. It originally took advantage of an easy network configuration and small memory footprint of the IPX/SPX protocol stack. Since 1991 the TCP/IP implementation is available.

Novell eDirectory uses NCP for synchronizing data changes between the servers in a directory service tree.

Technical information 

The original IPX/SPX server implementation was provided only for Novell NetWare platform and now is obsolete. The TCP/IP implementation uses TCP/UDP port 524 and relies on SLP for name resolution.

For NCP operation in IPX/SPX networks the bare IPX protocol was used with Packet Type field set to 17. On the workstation (client station) side the IPX socket number of 0x4003 was used, on the server side the socket number of 0x0451.

The NCP PDU has the following structure:

The NCP Type field determines the type of operation:

Individual requests are identified by the Sequence Number (modulo 256). The Connection Number identifies an individual client station connection on the server. Novell Netware servers of version up to 2.x supported up to 255 connections and the Connection Number occupied only 1 octet. Later it was extended to 2 octets. Task number has value 3 in requests and 1 in replies. The Data field starts with NCP Function number octet which distinguishes individual services.

The contents and the length of the rest of the Data field depends on the NCP Function.

Potassium silicate. Potassium silicate is the name for a family of inorganic compounds.  The most common potassium silicate has the formula K2SiO3, samples of which contain varying amounts of water.  These are white solids or colorless solutions.

Synthesis, structure, reactions
Potassium silicate can be synthesized in the laboratory by treating silica with potassium hydroxide, according to this idealized equation:

These solutions are highly alkaline.  Addition of acids causes the reformation of silica.

K2SiO3 adopts a chain or cyclic structures with interlinked  monomers.  Each Si is tetrahedral.

Uses

Woodwork protection against fire
Impregnation of wood with a potassium silicate solution is an easy and low-cost way for rendering the woodwork of houses secure against catching fire. The woodwork is first saturated with a diluted and nearly neutral solution of potash silicate. After drying, one or two coats of a more concentrated solution are usually applied.

Horticulture
In horticulture, potassium silicate is used as a soluble source of potassium and silica. It makes the growing medium more alkaline.

It is also used as a supplement (in conjunction with normal fertilizer) for the numerous benefits that increasing the availability of silicon compounds has.  Silicon-containing compounds are valuable to a plant, and serve to support the plant. Stems thicken, the plant becomes more tolerant to drought and resists wilting, and the plant gets larger leaves and fruit (because the stem can support more weight). The thicker cell walls of the plant also provides an added mechanical resistance to sap-sucking insects (e.g. spider mite) and various pathogenic fungi (e.g. powdery mildew).

Industrial uses
Some metal cleaning formulations use potassium silicate, which also serves as a corrosion inhibitor. It also finds various uses in the fabrication of welding rods and cosmetics.

Silicon dioxide production 
Potassium silicate may also be employed in glass recycling as an intermediate step in obtaining relatively pure and cheap SiO2 for further processing (e.g. for fused glass).

Safety
Potassium silicate is strongly alkaline.

Thomas Lomar Gray. Thomas Lomar Gray (4 February 1850 – 19 December 1908) was a Scottish engineer noted for his pioneering work in seismology.

Early life
Born in Lochgelly, Fife, Scotland, Gray graduated in 1878 from the University of Glasgow with a BSc in engineering.  At Glasgow, he awarded the Cleland Medal for "An Experimental Determination of Magnetic Moments in Absolute Measurements.".

Career
At the recommendation of John Milne, he was hired by the government of Japan as a foreign advisor and arrived in Tokyo in 1879 to assume to post of Professor of Telegraph Engineering in the Physical Laboratories at the Tokyo Imperial University. Later, while working at the Imperial College of Engineering in Tokyo, he helped John Milne and James Alfred Ewing develop the first modern seismometers from 1880 to 1895. Although all three men worked as a team on the invention and use of seismographs, John Milne is generally credited with the invention of the first modern horizontal-pendulum seismograph.

Gray joined Milne and Ewing in founding the Seismological Society of Japan (SSJ) in 1880.

Gray served as Private Assistant to Sir William Thomson (Lord Kelvin), Professor of Natural Philosophy in Glasgow University from 1884 to 1887. Thomson also proposed Gray as a Fellow of the Royal Society of Edinburgh (FRSE)
 
Among Gray's colleagues in Japan was Thomas C. Mendenhall. Inn 1888, Mendenhall encouraged him to join the faculty of Rose Polytechnic Institute of Technology, now Rose-Hulman Institute of Technology in Terre Haute, Indiana in the United States. His title was Professor of Dynamic Engineering.  He was vice president of Rose Polytechnic from 1891 through 1908. He died on 19 December 1908 and is commemorated in a plaque by the entrance to the old drill hall in Lochgelly

Bridge line. A bridge line or bridge route or bridge traffic relates to an American rail carrier tasked primarily with moving traffic from one major carrier to another (hence the "bridge" moniker). Bridge lines often were located between two major cities, connecting rail carriers that served those cities and interchanging their cars. As railroads have continued to evolve and large Class I railroads have sought to keep cars on line (as well as collect the revenues for the tonnage moved over their own route miles), most bridge lines are now gone.

The most recent example of a "bridge" carrier being swallowed up was the Wisconsin Central. The WC was a bridge line for Canadian National's traffic out of Chicago to western Canada. Once CN had integrated its purchase of Illinois Central, there was no route for it to send trains to points in western Canada on its own rails. Rather than reroute the trains through Michigan and around the Great Lakes, CN used the WC to forward its trains through Wisconsin and Minnesota to Canada. Eventually, CN bought the WC outright and integrated the line into its system, rather than pay the carrier to move its freight.

Light aircraft. A light aircraft is an aircraft that has a maximum gross takeoff weight of  or less.

Light aircraft are used as utility aircraft commercially for small-scale passenger and freight transport; for sightseeing, photography, cropdusting, and other so-called aerial work roles of civil aviation; for the personal-use aspect of general aviation; and in certain aspects of military aviation.

Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air.

Uses
Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, such as twin turboprops and very light jets, are often used as business aircraft. Most floatplanes also fall into the category of light aircraft.

Linotronic. The Linotronic imagesetters are a now common type of high-quality printer, capable of printing at resolutions of up to 2540 dots per inch. The Linotronic allowed graphic artists to cheaply set type that exceeded the quality of many phototypesetting systems in use at the time.  Although too expensive for homes or most offices, but cheaper than many other alternatives of printing, it was the graphic designer's dream: output by taking a PostScript file on a removable disk to a service bureau for output on the bureau's Linotronic.

Manufactured by Mergenthaler Linotype Company and popularized by the Adobe RIP, enabling PostScript language files to be imaged by the Linotronic imagesetter. Although it was the first commercial usage of PostScript, which began the emergence of graphics applications dominance by Adobe, the first popular use of PostScript was the Apple Laserwriter (succeeded a few months later by the LaserWriter Plus).

Adobe's RIPs have, generally, been named for United States rockets (Atlas, Redstone, etcetera), but Apple's RIP was of its own design, and was implemented using remarkably few integrated circuits (ICs), including PALs for most combinatorial logic, with the subsystem timing, DRAM refreshing, and rasterization functions being implemented in very few medium-integration PALs. Apple's competitors (i.e., QMS, NEC, and others) have generally used a variation of one of Adobe's RIPs with their large quantity of low-integration (i.e., Texas Instruments' 7400 series) ICs.

The latest RIPs are stand-alone fast PCs executing an x86 implementation of PostScript, with a special video output interface to the imagesetter.

Bargeboard. A bargeboard or rake fascia is a board fastened to each projecting gable of a roof to give it strength and protection, and to conceal the otherwise exposed end grain of the horizontal timbers or purlins of the roof. The word bargeboard is probably from the Medieval Latin bargus, or barcus, a scaffold, and not from the now obsolete synonym vergeboard.

History

Historically, bargeboards are sometimes moulded only or carved, but as a rule the lower edges were cusped and had tracery in the spandrels besides being otherwise elaborated. An example in Britain was one at Ockwells in Berkshire (built 1446–1465), which was moulded and carved as if it were intended for internal work.

Modern residential rake fascias are typically made of 2-by dimensional lumber, with trim added for decoration and/or weatherproofing later.

Deluxe Music Construction Set. Deluxe Music Construction Set (DMCS) is a 1986 music composition, musical notation, and playback package for the Amiga and Macintosh. The program was originally released as Will Harvey's Music Construction Set for the Apple II and other computers, but was redesigned (and the Will Harvey name dropped) for the deluxe version. DMCS was created by Geoff Brown and published by Electronic Arts (EA). Ariolasoft published the program in Europe under license from EA.

Summary 
DMCS was the first of a line of music programs for the Amiga to make use of its four voice 8-bit sample playback and MIDI synthesis. 
DMCS is more advanced than the 
first music application that EA made for the Commodore 64, Apple II, Atari 8-bit computers, and Atari ST, Music Construction Set. For example, it allows users to enter lyrics in with the musical score, though the lyrics are strictly for the user's benefit. Bach's Fugue in G minor "Little" is included as a sample score.

DMCS was originally released for the Mac. The Mac version uses a copy protection technique preventing the application from working with System 6.

Unreleased port
In 1986, a port by Randel B. Reiss for the Apple IIGS was written, which uses the built-in Ensoniq wavetable sample-based synthesizer. Screen shots appeared in various catalogues and was scheduled for a fall of 1987 release. The port was never publicly released, but its music engine was used for producing the soundtrack for the Apple IIGS game titles Zany Golf and The Immortal, both of which were written by Will Harvey.

Reception
After testing a beta of the Amiga version, Info stated that Deluxe Music "offers the most accurate standard music notation display and editing features I've ever seen ... it is a flexible, detailed composition program".
