Pitcairn XO-61. The Pitcairn XO-61 was an American autogyro designed by Pitcairn Aircraft. One of the last autogyros produced, in competition with the Kellett YO-60 and the Sikorsky R-4, it fell victim to cooling problems with its rear-mounted engine and the coming of the helicopter with its ability to hover.

Also known by the company model number PA-44 and the contract designation MX-157, the contract for the XO-61 was taken over by G&A Aircraft upon G&A's acquisition of Pitcairn Aircraft.

Root complex. In a PCI Express (PCIe) system, a root complex device connects the CPU and memory subsystem to the PCI Express switch fabric composed of one or more PCIe or PCI devices. A root complex is sometimes referred to PCI root bridge.

The root complex generates transaction requests on behalf of the CPU, which is interconnected through a local bus. Root complex functionality may be integrated in the chipset and/or the CPU. A root complex may contain more than one PCI Express port and multiple switch devices can be connected to ports on the root complex or cascaded.

Device Memory Map 

The PCIe Root Complex holds a master copy of a 'Type 1 Configuration Table' that defines the host memory space that is accessible from each Endpoint device.  In addition, each PCIe Endpoint device holds a master copy of their own memory space map in the host system memory as a 'Type 0 Configuration Table', this configuration table in each device allows the host to access the local memory of a PCIe device. Both the Type 1 and Type 0 configuration tables are set up by the Host Operating System that controls the Root Complex by a process known as enumeration and which acts to build a device memory map for the system by querying each bridge, and endpoint device connected on the bus network.  Similarly, a PCIe Bridge acts a tiered root complex with a "Type 0 Configuration Table".

Ryan YO-51 Dragonfly. The Ryan YO-51 Dragonfly was an observation aircraft designed and built by Ryan Aeronautical for the United States Army Air Corps (USAAC). A single-engined parasol wing monoplane, it was designed for optimum STOL capability, but although three prototypes proved highly successful in testing, the Stinson YO-49 was judged superior and no production contract was placed.

Design
The design of the YO-51 Dragonfly was typical for aircraft of its type, being optimised for the observation and liaison role, with emphasis on the ability to operate out of the smallest possible airfields. The Dragonfly was a high-wing braced parasol monoplane with fixed tailwheel landing gear, a two-seat open cockpit, and full-span slots and Fowler flaps for STOL capability. It was powered by a single Pratt & Whitney R-985-21 Wasp Junior radial engine.

At gross weight, the YO-51 could, without flaps, take off after a run of 400 feet, while with full flaps the takeoff run would be only 75 feet, or just four feet more than twice its own length. The Dragonfly was capable of maintaining level flight at speeds as low as , and was claimed as being capable of landing in a distance shorter than the length of the aircraft itself.

Operational history
Nicknamed the "flying motorcycle", three YO-51 aircraft were acquired by the United States Army Air Corps to take part in a fly-off evaluation against the Stinson YO-49 and Bellanca YO-50 to supply a new observation and liaison aircraft for use by the USAAC. The YO-51 was the heaviest of the three aircraft evaluated.

Although the Dragonfly was considered satisfactory during its flight testing, conducted at Wright Field in Ohio, the Stinson machine won the production contract, and no further YO-51s were built.

Singanallur Lake. Singanallur Lake is a lake in Singanallur, Coimbatore, South India. It is spread over an area of  and has an average depth of . It is one of the 9 large lakes in the city.

Hydrography
The lake is fed by canals derived from Noyyal river. The lake also receives water from Sanganur drain and sewage water. The water can be released through two sluice gates on the lake. In 2010, pipes were laid to connecting the lake to Valankulam Lake to drain excess water during floods.

Flora and fauna

Eichornia crassipes is the main aquatic plant species causing eutrophication of the lake. The insect species  included four orders Orthoptera, Coleoptera, Hemiptera and Odonata.

The lake supports a rich bio-diversity consisting of plankton, butterflies, resident and migratory birds. Various species of butterflies including common Mormon, joker butterfly, glassy tiger and plain tiger have been spotted in the lake. Over 110 species of birds have been spotted in the lake. The spot-billed pelican, painted stork, openbill stork, ibis, Indian spot-billed duck, teal and black-winged stilt visit the lake during their migration. Various families of birds recorded include cormorants, herons, storks, ibis, kites, ducks, francolin, crakes, jacanas, plovers, sandpipers, terns, doves and pigeons, parakeet, cuckoos, owls, swifts, kingfishers, bee-eaters, rollers, barbets, woodpeckers, larks, swallows, wagtails, shrikes, bulbul, robin, babblers, warblers, flycatchers, flowerpecker, sunbirds, munias, sparrows, weavers, myna, orioles, drongos and crows.

Fishing
Fishing is carried out by local fishermen and enthusiasts. In the 2000s, due to encroachment and the fishes were infected with metals and pathogens from polluted waste water discharged from the sewage.

Transport
A railway track connecting  and  passes over the lake.

Environmental concerns
In 2006, the lake was encroached by water hyacinth and contaminated due to effluents released into the lake. In 2014, Coimbatore Corporation unveiled a plan to clear the encroachments and use the lake for recreation. In January 2015, the lake was cleared and made ready for commercial tourism purposes.

Recreation
Singanallur boat house was opened in 2005 and was closed in 2009 due to poor maintenance. In 2014, after the Coimbatore Corporation plan to de-silt the lake, the boat house was renovated. The Government of Tamil Nadu will introduce water sports and boating on the lake. Despite the increased inflow of tourists since renovation, tourists complain of unavailability of boats.

John Fowler (British Army officer). Lieutenant-General Sir John Sharman Fowler,  (29 July 1864 – 20 September 1939) was a British Army engineer officer who specialised on telegraph on signals, and who was later Commander of British Forces in China.

Early life and education
Fowler was born in Navan, County Meath, the second son of Robert Fowler and Letitia Coddington. He was educated at Cheltenham College and the Royal Military College, Sandhurst. His elder sister Louisa married Sir Alexander Godley.

Military career
Fowler was commissioned into the Royal Engineers in January 1886. He took part in the Izazai expedition in 1892, was promoted to captain on 24 September 1895, and went to Chitral in the North West Frontier of India in 1896. He also took part in the Tirah Expeditionary Force in the North West Frontier of India in 1897. He attended the Staff College, Camberley from 1898 to 1899.

Interstate XBDR. The Interstate XBDR was a design for an assault drone - an early television-guided missile - powered by two jet engines, that was designed by the Interstate Aircraft and Engineering Corporation during the latter stages of the Second World War for use by the United States Navy. Wind tunnel tests of a scale model were conducted, however no full-scale examples of the aircraft were built before the project was cancelled.

Design
Referred to at the time as an "assault drone", and the only aircraft ever designated in the 'BD' series, the XBDR-1 was designed by Interstate in response to a Navy requirement in late 1943 and early 1944. The aircraft featured a tailless design, and was essentially a flying wing with a small vertical stabiliser. The XBDR-1  was intended to be powered by two Westinghouse 19B axial-flow turbojet engines, which were to be buried in the wing near the wing roots. The planned warload was not detailed, however it was planned that the assault drone would be guided to its target via a television link.

Testing and Cancellation

Two prototypes (BuNos 37635 and 37636) were ordered, and tests of a 1/17-scale model of the XBDR were conducted in a NACA gust tunnel at Langley Field in 1944. Requested by the Bureau of Aeronautics in an attempt to determine the load factors of the unusually configured aircraft, these tests initially encountered difficulty with the center of gravity of the model, but once this was resolved the tests were successfully carried out, and a gust factor of 1.22 was recommended for use in the design. Despite the successful testing the Navy decided not to pursue full-scale development of the aircraft, and the order for the two prototypes was cancelled.

George Henry Livens. George Henry Livens (1886–1950) was a British mathematician best known for his work on electromagnetics, elasticity and thermodynamics.

He graduated from Cambridge University in 1910 and was awarded the Smith Prize in 1911 for an essay entitled "The influence on density on the position of the emission and absorption lines in a gas spectrum" and was elected fellow of Jesus College. He went on to an appointment as Lecturer in Geometry at Sheffield University, a post he held until 1919 when he was appointed Fielden Lecturer in  Manchester. He left this post for a chair at the University College of South Wales in 1922 where he remained for the rest of his career. One of his students was Rosa M. Morris.

Livens's main work was in electrical theory publishing a book "The Theory of Electricity" in 1918. His work included 
problems concerned with the motion of charged spheres, the connection between optical properties and
electron theory, leading to a new form of the electron theory of the rotatory
power in solutions and isotropic media; another topic was the electron theory of metallic conduction.

Soft chemistry. Soft chemistry (also known as chimie douce) is a type of chemistry that uses reactions at ambient temperature in open reaction vessels with reactions similar to those occurring in biological systems.

Aims
The aim of the soft chemistry is to synthesize materials, drawing capacity of living beings - more or less basic - such as diatoms capable of producing glass from silicates dissolved. It is a new branch of materials science that differs from conventional solid-state chemistry and its application to the intense energy to explore the chemical inventiveness of the living world. This specialty emerged in the 1980s around the label of "chimie douce", which was first published by the French chemist, Jacques Livage in Le Monde, 26 October 1977. French hits, the term soft chemistry is employed as such in the early twenty-first century  in scientific publications, English and others. His mode of synthesis is similar generally for reactions involved in the polymerizations based on organic and the establishment of solutions reactive energy intake without essential polycondensation. The fundamental interest of this kind of polymerization mineral obtained at room temperature is to preserve organic molecules or microorganisms that wishes to fit. The products obtained by means of the so-called soft chemistry sol-gel can be stored in several types:

 mineral structures of various qualities (smoothness, uniformity, etc.)
 mixed structures combining inorganic and organic molecules on mineral structures
 wrapper complex molecules and even microorganisms maintaining or optimizing their beneficial characteristics.

The early results have included the creation of glasses and ceramic with new properties. These different structures are more or less composite mobilized a wide range of applications ranging from health to the needs of the conquest of space. Beyond its mode of synthesis, a compound with the label soft chemistry combines the advantages of the mineral (resistance, transparency, repetition patterns, etc.) and now exploring the potential of the biochemistry and organic chemistry (interface with the organic world, reactivity, synthesis capability, etc.). According to its practitioners, "soft chemistry" is only in its early success and opens up vast prospects.

ASi-Profile. ASi-Profile is a 3D-CAD add-on application for Autodesk Inventor developed by company ITB Paul Schneider.

Uses
The software aims to extend the field of application of Autodesk Inc.'s CAD software Autodesk Inventor, which is usually used for mechanical construction in mechanical engineering and plant engineering. ASi-Profile enables the user to create supporting structures, substructures, control- and maintenance platforms, stairways, barriers, etc. which are typical elements in the constructional steelwork area.

Use in mechanical engineering, plant engineering
Conventional 3D CAD systems for mechanical engineering usually lack of functions to create steel constructions. As an add-on application, the software tries to fill the gap between mechanical engineering and constructional steelworking, enabling the designer, for example, to create a supporting frame for a machine or the required maintenance platform in the same software.

Use in locksmithing, metal fabrication
The scope in locksmithing and metal fabrication is often to plan and design stairways, platforms, balconies or railings, etc., with the intention of creating a customized, individual structure, setting a special focus on its design. ASi-Profile is used to simplify the construction process and to create realistic views of the structures.
