Abhay-class corvette. The Abhay-class corvettes of the Indian Navy are the customised variants of the Soviet s. The class was primarily intended for coastal patrol and anti-submarine warfare. The last ship of the class is expected to be decommissioned by 2025. The class is being replaced by Arnala-class and Mahe-class of Anti-Submarine Warfare Shallow Water Craft (ASW SWC). The ships formed the 23 Patrol Vessel Squadron of the Indian Navy.

Description 
Abhay class is modified from Pauk II class under Project 1241 PE. The ships were built at Volodarski shipyard in the former Soviet Union. Abhay class vessels are longer, have larger torpedo tubes and improved electronics when compared to the Pauk I class vessels. The ships in the class were named after former Abhay-class seaward defence boats.

Abhay class is to be upgraded with Abhay integrated sonar system developed by Naval Physical and Oceanographic Laboratory.

Service history 

INS Agray was damaged in 2004 when an anti-submarine rocket fired from the onboard RBU-1200 launcher misfired and exploded on the side of the ship. Following the accident, the vessel was converted into a patrol vessel and a trials ship for electronic warfare systems.

The Ministry of Defence cleared acquisition of 16 shallow water anti-submarine vessels to replace the Abhay class of vessels.

INS Ajay was decommissioned on 19 September 2022 after 32 years of service in the Indian Navy.

René Warcollier. René Warcollier (8 April 1881 – 23 May 1962) was a French chemical engineer and parapsychologist. He was president of the Institut Métapsychique International, and edited and wrote theoretical and experimental reports for its journal.

Biography

Warcollier was born on 8 April 1881 at Omonville-la-Rouge in Paris. He obtained a degree in chemical engineering in 1903 from the École Nationale Supérieure de Chimie. He patented several processes related to the synthetic production of precious stones, and invented special screens for movie projection.

In parapsychology, Warcollier first served as treasurer of the Institut Métapsychique International (1929–1938), then editor of its journal, the Revue Métapsychique, (1938–1940), and then as its president (1951–1962). He died on 23 May 1962.

Studies

Warcollier's main parapsychology studies involved experiments using a telepathy design in which one or more "agents" observed a target image while one or more "percipients" attempted to "blindly" reproduce it. Much of his work following from 1922 involved "batteries" of senders and receivers stationed across France; and he also used sender-receiver teams stationed between France and New York, and France and Great Britain. He worked with Gardner Murphy.

Supporters of Warcollier say that his experimental method was an advance in terms of evidence and informativeness on earlier studies using drawings of real objects as target stimuli. A major contemporary critic was the British parapsychologist Samuel Soal. He argued that Warcollier's method was sub-optimal as the targets were not sufficiently selected at random, and correspondences between targets and responses were identified without formal and objective limitations.

Warcollier discarded the statistical method and attempted to obtain direct evidence for telepathy. He claimed from his experiments that men transmit thoughts
better than women but that women are better receivers. He also stated that younger people are more sensitive to mental impressions than the elderly. His experiments were well received by parapsychologists such as Harry Price but were criticized by the scientific community.

Warcollier reported his experiments in numerous articles, principally within 56 articles in the Revue Métapsychique published between 1924 and 1962, including "La télépathie expérimentale" (1926) and "Étude de dessins télépathiques de M. Vigneron au cours de vingt ans d'expérimentation" (1951). Results and reflections upon them were also published in his several books, including La Télepathie (1921) and La Métapsychique (1940; 1946). Gardner Murphy arranged to have La Télepathie translated and published in the United States, with additional material from Warcollier's articles, and an address he gave to the Sorbonne in 1946, as Mind to mind (1938, 1963).

Directorate for Studies and Experiments. The Directorate for Studies and Experiments (Italian acronym DSSE) was an aeronautic tests centre established in the 1930s at Montecelio, near Rome. It took over the patrimony of experience  gathered by the Italian Royal Airforce on the location since the end of World War I. In the 1920s the centre facilities already included a wind tunnel. Around the DSSE soon a new town developed, Guidonia. In the last years before the outbreak of World War II, DSSE grew into a world-known aeronautics testing ground. At the Directorate for Studies and Experiments  there were many advanced facilities, such as one of the first wind tunnels, an ultrasonic tunnel, the weightlessness simulator called ‘pneumatic tank for high altitude’ and a centrifugal apparatus to study loss of orientation in space. Many of these tools were used by the Center for Studies and Research in Aeronautical Medicine research and anticipated more advanced technological equipment to be employed later In that field and Space activities at large. in Space Medicine. The more outstanding examples are the flight simulator provided with a cycle-ergonometer, the centrifugal device, the pressurized suit and the airtight cabin: these last two pieces of equipment were used by Mario Pezzi to attain his altitude records in the 1940s.
DSSE was meant to become the only State Agency devoted to aeronautics research coordinating private firms too, such as Savoia-Marchetti, Caproni, Fiat, CANT and others,  in order to avoid overlapping and attain maximum efficiency. DSSE collected as well foreign data on aeronautic matters and overlooked military and university research. The aim was to become a unique collector of experiences and information such as to promote the Italian Royal Airforce as world leader. That aim was only partly attained especially in airplane engine studies where DSSE myopia hampered the development of high performance power plants.

Demolition vehicle. A demolition vehicle is a vehicle used to demolish buildings and other structures.

Military forces require such vehicles to clear obstacles, fortifications and rubble so that they can safely advance. Military engineers may use a variety of specialised vehicles including armoured bulldozers and explosive robotic drones.

History
The first being the prototypes of explosive robotic drones of Aubriot-Gabet 'land torpedoes' invented in France in 1915 and the Crocodile Schneider-Creusot, 20 examples were put into service with the 2nd French Army in July 1915.

Examples used during the Second World War include the German Goliath, the AVRE variant of the Churchill tank and the Centaur bulldozer. The Israel Defence Forces developed armoured bulldozers such as the IDF Caterpillar D9 in the 1950s and has used these with success in several of its conflicts.

Specialist demolition vehicles may be used by civilian contractors. Volvo produce a range of tracked vehicles equipped with lengthy hydraulic arms and a variety of attachments including drills, grabs, pincers and scoops.

ENEC Mark. ENEC is the high quality European mark for electrical products that demonstrates compliance with European safety standards.

ENEC Description
ENEC is an abbreviation for "European Norms Electrical Certification".

These four letters are part of the registered trademark that demonstrate that a product has been certified by one of the national certification institutes in Europe. Today, there are 25 certification institutes (also called certification bodies) that are signatories of the agreement.

Apart from the mark itself, there are also two digits numbers that indicate which certification body has issued the ENEC certification.

The ENEC agreement was originally started with a view to providing manufacturing of luminaires with a joint European certification mark to replace all the different national marks. In 1999, the agreement was expanded to include:
 Lighting
 Components for lamp holders
 IT
 Electric office equipment
 Safety isolating transformers
 Isolating transformers and separating transformers
 Power supply units
 Switches

ENEC is a product certification type 5. In particular, this scheme includes factory inspection at the manufacturer's premises.

Established since 2010, ENEC is trying to be the standard for safety reassurance in the European Market.

The application of the ENEC Mark to an electrical product ensures that it complies with the relevant European safety standards and has to be accepted by all member states. Monitoring of product and production provides safety assurance for the lifetime of the ENEC certification.

Household appliances, electronic equipment, lighting
Compliance with the EU low-voltage-directive
Reduced license costs
Evidence in case of product liability claims

Obtaining the ENEC certificate
Testing and certification according to European standards. Product manufacturing monitored by an accredited inspection division like Electrosuisse SEV, Nemko, MIRTEC S.A, TSE or an equivalent partner organization for foreign production facilities to ensure consistent product compliance.

Loire 501. The Loire 501 was a single-engined French liaison and training flying boat of the 1930s produced by Loire Aviation. It was operated by the French Navy, remaining in service until 1940.

Design and development

In 1930, Loire Aviation, a subsidiary of the French shipyard Ateliers et Chantiers de la Loire  of Saint-Nazaire, started design of a single-engined flying boat for use as a trainer and a transport in France's overseas possessions.  The resultant aircraft, the Loire 50, was an amphibian high-winged monoplane, with a  pusher Salmson 9AB radial engine mounted above the wing.  Construction was all-metal, with fabric-covered wings. The French government ordered construction of a prototype Loire 50 (together with a prototype of the three-engined Loire 60 flying boat) on 31 March 1931.

The Loire 50 first flew on 7 September 1931. Although it was damaged in an accident in October, it was repaired and entered service in 1932 as a trainer. It was returned to Loire in February 1933, where it was modified with a more powerful ( Hispano-Suiza 9Qd engine, becoming the Loire 50bis, flying in this form on 18 October 1933.  An order was placed for six aircraft similar to the Loire 50bis, designated Loire 501, delivery starting by the end of 1933.  The Loire 501 remained in service at the start of the Second World War, with the last example still in use at Karouba in Tunisia on 15 August 1940.

Loire-Nieuport 10. The Loire-Nieuport 10 was a 1930s French prototype  long-range maritime reconnaissance and combat floatplane produced by Loire-Nieuport, a joint venture between Loire Aviation and Nieuport-Delage. It was an attempt to answer the requirements for the Navy's programme Hydravion éclaireur de combat ("Combat reconnaissance seaplane") for a large floatplane capable of acting as a torpedo bomber or reconnaissance aircraft.

Development and design
Design of the Loire-Nieuport 10 started in 1937, with the resultant aircraft being a twin-engined monoplane of all-metal stressed-skin construction with inverted gull (or W-shaped) wings.  It was powered by two Gnome-Rhône 14N  radial engines mounted above the wings, with the twin large floats on pylons under the wing, directly beneath the engines.  The deep fuselage accommodated a crew of six, with pilot and co-pilot seated in tandem, while a glazed nose was provided for the bomb-aimer/navigator.  Defensive armament was a machine gun in the nose, with another firing through a ventral hatch, and a 20 mm cannon in a dorsal turret, while it could carry two torpedoes or 1,200 kg (2,700 lb) of bombs in an internal bomb-bay.

The prototype Loire-Nieuport 10, the L.N.10-01, first flew at Saint-Nazaire on 21 July 1939. However, on 10 December 1939, the programme was cancelled as the French Navy had decided to use land based aircraft instead, with no production following of either the LN.10 or its competitors.  It was destroyed at Bordeaux in June 1940 to prevent capture by German troops.

The fuselage of the Loire-Nieuport 10 was used for the SNCAO 700 four-engined bomber prototype, of which a prototype was built but failed to fly due to the Armistice.

Coiled tubing umbilical. Coiled tubing umbilicals are a type of piping used in oil and gas wells.

Background
The piping can be used during interventions. They encapsulate multiple coiled tubing and electrical strings into a single string which can be deployed by one conventional unit.  These technologies allow for the deployment of complex pumps on coiled tubing.  Multiple strings in a casing may maintain a manageable shape for the tubing and eliminating the danger of ovalization.

Turbo51. Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi.

In the 1980s, Intel introduced the 8051 as the first member of the MCS-51 processor family. Today, hundreds of cheap derivatives are available from tens of manufacturers. This makes the architecture very interesting for professionals and hobbyists. It is surprising that this 8-bit architecture is still in use today, and is still so popular. Of all 8051 compilers, several widely used C compilers exist, but only a few Pascal compilers. Turbo51 is available as freeware and was created with the goal to make a Pascal compiler for MCS-51 processors that will be as fast as Turbo Pascal, will use the same syntax and will generate high quality optimized code.

Language dialect

Turbo51 uses Borland Turbo Pascal 7 dialect. The syntax was extended with some constructs to support specific features of MCS-51 processors.
