Cockatoo Docks & Engineering Company. The Cockatoo Docks & Engineering Company was a ship building and maintenance company which operated the Cockatoo Island Dockyard on Cockatoo Island in Sydney, Australia, between 1933 and 1992.

History

The Cockatoo Docks & Engineering Company commenced trading on 1 March 1933 taking a 21-year lease over the dockyard on Cockatoo Island from the Federal Government.

Having held a minority shareholding since 1937, in 1947 Vickers-Armstrongs became the majority shareholder. In February 1954, the lease was renewed for a further 20 years and 8 months, and again from 1 January 1972 for 21 years.

In February 1984, Vickers merged its Australian interests were with the Commonwealth Steel Company to form Comsteel Vickers, Vickers and BHP each owning 38%, with the remaining 24% held by smaller investors. On 4 June 1986, the company was purchased by Australian National Industries (ANI).

As part of a review of Australia's ship building capabilities, the Federal Government decided in 1987 the lease would not be renewed. Although consideration was given to terminating the lease early, in the end it ran its course until 31 December 1992, although the only work performed in the last 18 months was decommissioning the dockyard. A lengthy legal action over various costs and liabilities between the government and ANI was settled in May 1997.

Bayesian inference using Gibbs sampling. Bayesian inference using Gibbs sampling (BUGS) is a statistical software for performing Bayesian inference using Markov chain Monte Carlo (MCMC) methods. It was developed by David Spiegelhalter at the Medical Research Council Biostatistics Unit in Cambridge in 1989 and released as free software in 1991.

The BUGS project has evolved through four main versions: ClassicBUGS, WinBUGS, OpenBUGS and MultiBUGS. MultiBUGS is built on the existing algorithms and tools in OpenBUGS and WinBUGS, which are no longer developed, and implements parallelization to speed up computation. Several R packages are available, R2MultiBUGS acts as an interface to MultiBUGS, while Nimble is an extension of the BUGS language.

Alternative implementations of the BUGS language include JAGS and Stan.

Bowman 42. The Bowman 42 is an ocean-cruising yacht produced by Rustler Yachts of Falmouth. The yacht is traditionally lined and styled, but is built from solid glassfibre composite with a fin and skeg underwater profile.

To achieve a good seakeeping ability for ocean cruising, the yacht is heavily constructed, and well ballasted. In addition, the yacht incorporates a strong skeg hung rudder. The production of the yachts on a semi-custom basis, and the small numbers of yachts produced each year, result in a significantly higher purchase cost than comparable yachts from mass-production companies. The yacht is available in various degrees of part-completion as well as in factory finished form.

Paddock Viaduct. The Paddock Viaduct, also known as the Main Street Viaduct, is a reinforced concrete bridge spanning the Trinity River in Fort Worth, Texas. Low-water crossings and ferries originally provided the only access across the Trinity River at this location, connecting the downtown area of Fort Worth with northern sections of the city. A two-lane suspension bridge, constructed near this site in the 1890s, proved inadequate for the growing population. This span, designed by the St. Louis engineering firm of Brenneke and Fay, was completed in 1914. It was the first reinforced concrete arch in the nation to use self-supporting, reinforcing steel. The bridge is named in honor of B. B. Paddock, former State Legislator and Mayor of the City (1980).

The bridge was built in 1913 and renovated in 1965 and 1988. It was added to the National Register of Historic Places on March 15, 1976.

Aussi Also. The Aussi Also was a failed attempt to start a large-scale motorcycle manufacturing operation in Melbourne, Victoria just after the end of World War I.

Prototype
The Russell, Walsh & Hitchcock company had previously been in the metal trade, making fuel tanks, mudguards and other parts for both motorcycles and motor cars. By the end of 1919, William and Isaac Walsh had built a prototype motorcycle, powered by a 3.5 hp two-stroke engine. The bike was found to be underpowered, due to lack of crankcase compression. The brothers also built at least two 7-9 hp V-twin engined bikes for racing and publicity purposes.

Company created
In May 1920 the Aussi Also Motors & Manufacturing Company Ltd was created for volume production. Advertising suggested that a large, modern factory and substantial workforce were ready for production. In reality, the workshop was a dirty, dark ex-smelting and tinsmith shop with little equipment.

Pricing
Prices for the four planned models were as follows:

 65 pounds – single cylinder two-stroke
 65 pounds – twin cylinder four-stroke
 95 pounds – twin-cylinder two-stroke
 110 pounds – twin-cylinder four-stroke

An innovative feature was that the rear wheel could be replaced by a fly wheel, thus making the motorcycle a stationary engine.

Production claims
The company claimed that by June 1920 it had 40 bikes in various stages of construction, and that the factory could turn out 25 bikes a month, with a workforce of approximately 50 employees.

Company failure
Serious production never took place, due to negative publicity regarding the failings of the prototype.
William Marsh advertised the prototypes for sale, while Isaac returned to the family farm at Kilmany.

List of LM-series integrated circuits. The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced since late 1965; some were groundbreaking innovations. As of 2007, many are still being used. The LM series originated with integrated circuits made by National Semiconductor. The prefix LM stands for linear  monolithic, referring to the analog components integrated onto a single piece of silicon. Because of the popularity of these parts, many of them were second-sourced by other manufacturers who kept the sequence number as an aid to identification of compatible parts. Several generations of pin-compatible descendants of the original parts have since become de facto standard electronic components.

Notes 
 Suffixes that denote specific versions of the part (e.g. LM305 vs. LM305A) are not shown in this list.
 Obsolete 4-bit microprocessors of the LM6400 family, manufactured by Sanyo, have no relationship to the analog LM series and are not included in this list.
 The first digit of each part denote different temperature ranges. Mostly, LM1xx indicates military-grade temperature range of -55 °C to +125 °C, LM2xx indicates industrial-grade temperature range of -25 °C to +85 °C and LM3xx indicates commercial temperature range of 0 °C to 70 °C.
 Some obsolete parts continue to be manufactured by different companies other than the original manufacturer.

Atomic beam. Atomic beam is special case of particle beam; it is the collimated flux (beam) of neutral atoms. The imaging systems using the slow atomic beams can use the Fresnel zone plate (Fresnel diffraction lens) of a Fresnel diffraction mirror as focusing element. The imaging system with atomic beam could provide the sub-micrometre resolution.

History
In 1911, Louis Dunoyer observed sodium vapor 'rays' in a vacuum chamber. Learning from that experience, Otto Stern worked with Walther Gerlach to produce silver atom beams for their historic Stern–Gerlach experiment, providing the first evidence of atomic scale quantization.

In 1930, Immanuel Estermann and Stern reflected a helium beam from lithium fluoride observing the first atomic matter wave diffraction peaks in the reflected intensity.

Mackie International. Mackie International (originally known as James Mackie & Sons) was a textile machinery engineering plant and foundry in Northern Ireland until 1999. At its height, James Mackie & Sons was one of the largest employers in Belfast. “Mackie's”, as they were known locally, were a major supplier of munitions during World War II.

Background
The company was founded by James Scrimgeour in the 19th century but he got into financial difficulties and in 1858 the company was taken over and renamed by his manager, James Mackie.  It was still owned and run by the Mackie family until the early 1970s at which time the family gave the company to its employees to be run as a workers cooperative.  

In 1955 the company built a factory in India for the manufacture of machinery for jute mills.  This was taken over by the Government of India in 1978.  Through various changes it still exists as Lagan Engineering Company Ltd, a joint venture with the Government of India.

United States President Bill Clinton made a speech at the Belfast site in 1995, addressing a mixed audience in light of the beginning of the Northern Ireland peace process. In 2001 the Industrial Development Board bought the site for redevelopment, which resulted in the Springvale Business Park.

Structure–activity relationship. The structure–activity relationship (SAR) is the relationship between the chemical structure of a molecule and its biological activity. This idea was first presented by Alexander Crum Brown and Thomas Richard Fraser at least as early as 1868.

The analysis of SAR enables the determination of the chemical group responsible for evoking a target biological effect in the organism. This allows modification of the effect or the potency of a bioactive compound (typically a drug) by changing its chemical structure. Medicinal chemists use the techniques of chemical synthesis to insert new chemical groups into the biomedical compound and test the modifications for their biological effects.

This method was refined to build mathematical relationships between the chemical structure and the biological activity, known as quantitative structure–activity relationships (QSAR). A related term is structure affinity relationship (SAFIR).

Structure-biodegradability relationship
The large number of synthetic organic chemicals currently in production presents a major challenge for timely collection of detailed environmental data on each compound.  The concept of structure biodegradability relationships (SBR) has been applied to explain variability in persistence among organic chemicals in the environment.  Early attempts generally consisted of examining the degradation of a homologous series of structurally related compounds under identical conditions with a complex "universal" inoculum, typically derived from numerous sources.  This approach revealed that the nature and positions of substituents affected the apparent biodegradability of several chemical classes, with resulting general themes, such as halogens generally conferring persistence under aerobic conditions.  Subsequently, more quantitative approaches have been developed using principles of QSAR and often accounting for the role of sorption (bioavailability) in chemical fate.

GWR 7800 Class 7821 Ditcheat Manor. Great Western Railway 7800 Class No. 7821 Ditcheat Manor is a preserved British steam locomotive.

The second of the last batch of 10 engines of the thirty-strong class, 7821 was actually built by British Railways in 1950. Like most of the class of lightweight 4-6-0s, it was allocated to lines in Mid Wales, but was also based Oxley and Newton Abbot. 7821 was withdrawn in November 1965 and was sent to Woodham Brothers scrapyard in Barry, Vale of Glamorgan, South Wales.

Rescued from Barry in 1980, it was sent to the embryonic Gloucestershire Warwickshire Railway, before moving to the Llangollen Railway and then Swindon, restoration being completed in 1998, when it first steamed at the West Somerset Railway. The loco then worked on the Great Central Railway in Leicestershire, but in late 2005 moved to the Cambrian Railways Trust. 7821 moved again in 2005 to the Churnet Valley Railway where it served its last months of its boiler ticket in traffic.

In 2007, the West Somerset Railway Association bought 7821 from its private owner, in part funded by reselling GWR 0-6-0PT No. 6412 to its original owner, the South Devon Railway. The locomotive was initially moved to , and then in 2010 to . In light of a mechanical examination showing that the locomotive needed extensive and expensive chassis and boiler work, whilst funding is raised for its overhaul the WSRA agreed a static display contract with the Museum of the Great Western Railway, Swindon for a minimum contract period of five years. The locomotive was subsequently relocated to the museum by road on 14 November 2010, where it presently resides and is due to stay until November 2020. On 21 August 2018, the locomotive was relocated to the nearby Swindon Designer Outlet in place of classmate No. 7819 Hinton Manor.
