French ship Dupuy de Lôme (A759). Dupuy de Lôme (A759), named after the 19th century engineer Henri Dupuy de Lôme, is a ship designed for the collection of signals and communications beyond enemy lines, which entered the service of the French Navy in April 2006. In contrast to Bougainville, the ship that she replaced, Dupuy de Lôme was specifically designed for sea intelligence, pursuant to the MINREM project (Moyen Interarmées Naval de Recherche ElectroMagnétique, "Joint Naval Resources for Electromagnetic Research").

Design and description

Dupuy de Lôme was designed and built by Royal Niestern Sander shipyards in Delfzijl, The Netherlands with yard number 816. The Thales Naval France designed the electromagnetic intelligence part of the vessel.
She provides a 350-day-operational availability a year, out of which 240 can be spent at sea. The ship is operated by two naval crews, each composed of thirty-three sailors and another thirty-three technicians, and an optional complement of up to thirty-eight specialists, depending on the mission. The specialised personnel operates under the Direction du renseignement militaire.

Construction and career
On 21 June 2015, Dupuy de Lôme entered the Black Sea along with  as part of NATO's presence missions following the Annexation of Crimea by the Russian Federation.

In October 2021, during rising tensions between China and Taiwan, France confirmed that Dupuy de Lôme had been present in the Taiwan Strait recently, having been last seen sailing from Japan on 1 October 2021. As of July 2022, it was berthed in Bergen, Norway.

Augmented Satellite Launch Vehicle. The Augmented Satellite Launch Vehicle or Advanced Satellite Launch Vehicle (also known as ASLV) was a small-lift launch vehicle five-stage solid-fuel rocket developed by the Indian Space Research Organisation (ISRO) to place 150 kg satellites into LEO. This project was started by India during the early 1980s to develop technologies needed for a payload to be placed into a geostationary orbit.  Its design was based on Satellite Launch Vehicle. ISRO did not have sufficient funds for both the Polar Satellite Launch Vehicle programme and the ASLV programme at the same time and the ASLV programme was terminated after the initial developmental flights. The payloads of ASLV were Stretched Rohini Satellites.

Vehicle
The ASLV was a five-stage vehicle. Two strap-on boosters acted as a first stage, with the core stage igniting after booster burn out. The payload capacity of the ASLV was approximately  to an orbit of  with a 47-degree inclination.

At liftoff, the ASLV generated  of thrust. It was a  rocket, measuring  in length with a core diameter of . The height to diameter ratio of ASLV was very large which resulted in the vehicle being unstable in flight.  This was compounded by the fact that many of the critical events during a launch like the core ignition and the booster separation happened at the Tropopause  where the dynamic loads on the launcher was at the maximum. The aerodynamic characterization research was conducted at the National Aerospace Laboratories' 1.2m Trisonic Wind Tunnel Facility.

History
The ASLV made four launches, of which one was successful, two failed to achieve orbit, and a third achieved a lower than planned orbit which decayed quickly. The type made its maiden flight on 24 March 1987, and its final flight on 4 May 1994.

Launch history
All four ASLV launches occurred from the ASLV Launch Pad at the Sriharikota Range. For vertically integrated ASLV, many SLV-3 ground facilities were reused but a new launch pad with retractable Mobile Service Structure was constructed within the same launch complex.

Motion compensator. A motion compensator is a device that decreases the undesirable effects of the relative motion between two connected objects.

Description 
A motion compensator is a device that decreases the undesirable effects of the relative motion between two connected objects. The motion compensator does not prevent the motion, but tries to eliminate the negative effects of the movement. These negative effects include (1) the changes in force and stresses, and (2) the hysteresis, i.e., the rapid start-and-stop "jerking" of the objects.

Motion compensators are usually placed between a floating object and a more stationary object, such as a vessel or a structure fixed to the seabed. Most general motion compensators will compensate for movement in all directions  

The simplest motion compensator is the anchor chain of a ship. Not only does the anchor prevent the ship from drifting, but the chain itself dampens the movement of the ship due to undulating motion of the waves.  Generally, motion compensators are implemented as springs. For very large forces (dozens to hundreds of tonnes), the springs are implemented as gas springs: hydropneumatic devices — a plunger cylinder buffered by a volume of gas.

Heave compensation 

A heave compensator is a kind of motion compensator that compensates for movement in only one direction.

Examples 
Examples of heave compensators include:
Drill string compensators
Riser tensioners
Conductor tensioners
Guideline tensioners

GoTa. In telephony, GoTa or “Global Open Trunking Architecture” is a CDMA-based digital trunking system. The GoTA system was developed by ZTE, a Chinese manufacturer. It was approved as a CCSA standard  by the China Ministry of Industry  and Information Technology in 2008 and accepted as an international standard by the ITU in 2012. The GoTA system can be used for both private and public trunking network applications.

GoTa is capable of providing a variety of trunking services: 
One-to-one private calls and one-to-many group calls
The ability to set the user's priority
The ability to perform forced insertion/forced release based on the user's priority
The ability to provide special services such as system paging, group paging, sub-group paging, and dedicated Push-To-Talk services as required
The ability to classify the groups into permanent and temporary groups, in which the group members can be managed by the user.

In addition to trunking service, GoTa can provide value-added services such as short messages, location-based services and other data services. The original GoTa standard was developed for the 800 MHz band. GoTa is adapted to work in the 450 MHz band as well.

Notes
PTT PoC or Push to talk over Cellular is a feature similar to walkie-talkie that is provided over a cellular phone network.

New Zealand EB class locomotive. The New Zealand EB class locomotive was a class of five battery electric (later diesel-electric) locomotives built to perform shunting duties at the workshops of New Zealand's national rail network.

Introduction 
The first (later No. 29) was built in 1925 in the United States, and began its working life at Hamilton railway station in Frankton; then four years later it was transferred to Christchurch's Addington Workshops. That same year, four more were built at Hutt Workshops (No's 25 and 26) and Hillside Workshops (No's 27 and 28); they were stationed at main workshops around the country.

Conversion 
New batteries were required in 1937, and although conversion into diesel-electric locomotives was proposed, rebuilding was not undertaken until the early 1950s. In their new guise, the locomotives survived well into the 1970s.

Withdrawal 
The first to be withdrawn was EB 27 in 1976, and two years later, the class leader, EB 25, was also removed from service. It has been preserved by Auckland's Museum of Transport and Technology. The other three locomotives survived long enough to receive TMS numbers – EB 26 became EB 1809, EB 28 became EB 1815, and EB 29 became EB 1821. The latter two were withdrawn in 1980, but EB1809, now stationed in Napier, was reclassified as a member of the TR class, TR1003.  After it was withdrawn, it was saved for preservation and is now serviceable at the Silver Stream Railway.

Beryllide. Beryllide is an intermetallic compound of beryllium with other metals, e.g. zirconium, tantalum, titanium, nickel, or cobalt.  Typical chemical formulae are Be12Ti and FeBe5.  These are hard, metal-like materials that display properties distinct from the constituents, especially with regards to their resilience toward oxidation.

Applications and potential applications
Beryllides of cobalt and nickel have metallurgical importance as the precipitated phase in beryllium copper alloys. These materials are nonsparking, which allows them to be used in certain hazardous environments.

In nuclear technology, beryllides are investigated as neutron multipliers.  Unlike metallic Be, materials such as Be12Ti are more resistant to oxidation by water but retain the neutron-multiplying properties of the predominant isotope 9Be.

Spartan Scout. Spartan Scout, an Advanced Concept Technology Demonstration, is a crewless surface watercraft, also known as an unmanned surface vehicle (USV), developed by the United States in 2001, and first demonstrated in late 2003. The craft, a rigid hull inflatable boat, weighs 2 tons, and is  in length. It is equipped with a .50 caliber machine gun, as well as various sensors, such as electro-optical and infrared surveillance and surface search radar. The Spartan is capable of carrying a  payload.  According to a press release from the United States Navy, the Spartan Scout will also come in a  version, capable of carrying a  payload.

Although a two-man boat crew is needed to deploy the Spartan Scout, once deployed, it is capable of working autonomously or semi-autonomously. During its demonstration deployment, the Spartan Scout was configured for surface surveillance and force protection, although it can potentially be configured for more complex missions.

Henri Fabre. Henri Fabre (; 29 November 1882 – 30 June 1984) was a French aviator and the inventor of the first successful seaplane, the Fabre Hydravion.

Henri Fabre was born into a prominent family of shipowners in the city of Marseille. He was educated in the Jesuit College of Marseilles where he undertook advanced studies in sciences.

He intensively studied aeroplane and propeller designs. He patented a system of flotation devices which he used when he succeeded in taking off from the surface of the Etang de Berre on 28 March 1910. On that day, he completed four consecutive flights, the longest about 600 metres. the Hydravion has survived and is displayed in the Musée de l'Air in Paris. Henri Fabre was soon contacted by Glenn Curtiss and Gabriel Voisin who used his invention to develop their own seaplanes.

As late as 1971, Fabre said he was still sailing his own boat single-handedly in Marseille harbour.

He died at the age of 101 as one of the last living pioneers of human flight.

Thomas Hakon Grönwall. Thomas Hakon Grönwall or Thomas Hakon Gronwall (born Hakon Tomi Grönwall; January 16, 1877 in Dylta bruk, Sweden – May 9, 1932 in New York City, New York) was a Swedish mathematician. He studied at the University College of Stockholm and Uppsala University and completed his Ph.D. at Uppsala in 1898.  Grönwall worked for about a year as a civil engineer in Germany before he emigrated to the United States in 1904.  He later taught mathematics at Princeton University and from 1925 he was a member of the physics department at Columbia University.

In 1925 he started to collaborate with Victor LaMer, which led to his joining the Department of Physics at Columbia University as an associate in 1927. . There were no teaching obligations; he had complete control of his own time and an abundance of new intriguing problems to address in physical chemistry and in atomic physics. He developed an analytical solution to the Poisson-Boltzmann equation as it appears in the Debye–Hückel theory

Endust. Endust is an American brand of dusting aid produced by Nakoma Products. A dusting aid is sprayed on a dustcloth or dustmop, rather than directly on the furniture.

The brand was developed by O-Cedar, a division of Martin Marietta, in the 1950s; Drackett acquired O-Cedar from Martin Marietta in the 1960s. Originally, Endust consisted of odorless mineral spirits and 1,1,1-trichloroethane with a propellant blend of propane and isobutane. The Montreal Protocol targeted 1,1,1-trichloroethane as one of those compounds responsible for ozone depletion and banned its use beginning in 1996. Since then, the manufacture and use of 1,1,1-trichloroethane has been phased out throughout most of the world. Endust now contains mineral oil, petroleum distillates, aliphatic hydrocarbons, orange oil terpenes, and propellant.

Roger Blackwell Ph. D., of the Fisher College of Business says that Harry Drackett invented Endust. In the 1970s, however, the Drackett company offered a one-page company history indicating that they purchased the Endust product from a small company in Chicago.

The Federal Trade Commission allowed S. C. Johnson & Son to purchase Drackett in 1992, provided that they divested themselves of certain Drackett product lines within one year. Sara Lee bought Endust and Behold at that time while O-Cedar itself was divested to merge with Vining Industries. Sara Lee sold Endust and Behold to Nakoma Products in 2011.

In 2008, Endust released Endust Free, a fragrance free, hypoallergenic cleaning product that is asthma and allergy friendly.
