Shershen. The Shershen (; ) is a Belarusian third generation anti-tank guided missile (ATGM), based on Belarusian-Ukrainian ATGM Skif but reportedly with additional capabilities. Designed to defeat modern armored vehicles, protected objects (such as bunkers, pillboxes, earth-and-timber emplacements) and low-speed low-altitude targets (helicopters, UAVs).

Description 
The "Shershen" base version consists of a tripod, a universal combat module, an anti-tank guided missile, a guidance device (PN-S) and a remote control, which allows the control of the unit from up to 100 m (with a wire channel) and up to 300 m (with radio). The two-man crew's combat task is to assemble "Shershen", find the target and launch. The pre-launch procedures, which  include missile installation, PN-S connection and unit switch-on, take less than 2 minutes to complete. Once the missile is fired, the operator controls the "Shershen" and corrects the aim, if necessary, using the joystick on the remote control.

Shershen is designed to destroy armored vehicles equipped with explosive reactive armor (ERA) and can attack stationary and moving targets. Shershen also has automated fire and forget targeting mode that doesn't require manual tracking of a target.

The R-2V missile (can be used with "Shershen-Q" and unified with ATGM "Barier-V" ) extends the maximum range to 7,500m. The ability to use different types of missiles without any system modification, in addition to a wide spectrum of targets makes it possible to consider this system not only as an ATGM, but as a mobile defence-assault fire system for infantry support up to battalion level.

Variants 
 "Shershen" — base version.
 "Shershen-L" — light version (maximum range up to 2.5 km.)
 "Shershen-D" — version with two firing channels.
 "Shershen-Q" — version with two firing channels and auto lifting system (or without auto lift) for installation on a vehicle.

Norman R. Wright & Sons. Norman R. Wright & Sons is an Australian shipbuilding company.

History

In 1909 Norman Wright opened a shipbuilding business in Newstead. The first vessel completed was the Superb, a shallow draught gaff-rigged centreboard yacht. The yard mainly built pleasure craft, the largest being Francois, a 75-foot racing yacht.

In the 1930s, it moved to Bulimba. Following the outbreak of World War II in 1939, the building of recreational craft was suspended with the yard refitting various requisitioned vessels for war service. The Royal Australian Navy commissioned Norman Wright to build four Fairmile B motor launches.

After the war Norman Wright built commercial boats such as trawlers, luggers, and vessels for the tourist resorts. During this period, the yard built boats for the Barrier Reef islands of Lindeman, South Molle, Orpheus, Magnetic and Hayman. By the 1950s, Norman Wright's sons had assumed responsibility for the day-to-day operation.
 
Its most prominent builds in recent years have been catamaran ferries. In the 1990s, it built three for Matilda Cruises, Sydney, the Alice, Jillian and Megan and two for the State Transit Authority, the Anne Seargent and Pam Burridge.  Since 2004, it has built 13 ferries for Transdev Brisbane Ferries.

Boyd G.B.1. The Boyd G.B.1 was a two-seat monoplane designed for homebuilt aircraft kit building from glass fibre parts.

Design and development
Gary Boyd designed and built his G.B.1 over two-year period from 1977. The first flight was made in December 1979 and by early 1981 more than 70 flying hours had been achieved.

The G.B.1 was a monoplane almost entirely built from pre-moulded glass fibre components bonded together with polyester resin; these components, together with plans, were available to amateur builders. This structural approach was intended to make construction simple and also allowed the easy removal of the outer wing panels for transport. The prototype had a 1.8 L Volkswagen engine and a retractable, tailwheel undercarriage but the plans offered a choice of Volkswagen air-cooled engine installations in the 1.6 – 2.2 L range, as well as alternative fixed conventional undercarriage and retractable tricycle gear.

Variable electro-precipitator. A variable electro-precipitator (VEP) is a waste water remediation unit using electrocoagulation. The differences between a standard electrocoagulation (EC) unit and a variable Electro-precipitation unit are in the enhanced flow path and the unit electrode connections. The variable electro-precipitator's flow path has been designed to maximize retention time and to increase the turbulence of the water within the unit. This design aids in increasing the amount of effective treatment per gallon of water.

A major design weakness of the electrocoagulation units is the method used in connecting the electrode to the power source. These designs cause overheating, resulting in premature failure of the electrocoagulation reaction chamber. VEP reaction chambers are designed to resolve these performance issues by changing all electrode connections from the standard wet connection (inside the chamber) to an external dry connection. The VEP is cooler-operating, and has a longer chamber life than an electrocoagulation unit.

DRDO Sarvatra. The DRDO Sarvatra (Everywhere) also known as Sarvatra Multi-span Mobile Bridge System is a truck-mounted, multi-span, mobile bridging system developed by Armament and Combat Engineering Systems (ACE) and Research and Development Establishment (R&DE) Engineers of Defence Research and Development Organisation (DRDO) for the Indian army. Its production public company is Bharat Earth Movers Limited (BEML), Bangalore.

Design
The Sarvatra is a 75-meter, multi-span, mobile bridging system consisting of five scissor bridges made of aluminum alloy with a span of 15 meters, each mounted on a separate mobile platform. Each mobile platform is a modified Tatra T-815 VVN 8 x 8 chassis, drivable from both ends from a small cabin with required driving controls. Further, a microprocessor based control system is utilised to deploy and operationalise the system in less than 2.5 hours.

When the scissors bridge is opened, it is fitted with adjustable trestles to enable multiple units to be used to bridge wet and dry gaps. Five sections provide a total bridge length of 75 m, and four meters in width. The bridge is launched/recovered from either end. With the help of telescopic legs, the height of the bridge can be adjusted from 2.5 m to 6 m to reduce visibility.

The Sarvatra project was sanctioned in 1994 and completed development in October 1999 at a total cost of ₹230,000,000. It was approved for production in March 2000 after trials. The Sarvatra was to replace the East European PMS Bridges in the Indian army, which requires 57 Tatra vehicles to bridge 100 meters. In contrast, the Sarvatra, with just five sections, bridges 75 meters. At ₹600,000,000 per set, the PMS costs almost three times as much as a Sarvatra.

A 20 m variant of Sarvatra bridge system capable of bridging a gap of 100 meters has also been developed.

Silsbee effect. The Silsbee effect or Silsbee current refers to the effect by which, if the electric current through a superconductor exceeds a critical level, the superconducting state will be destroyed. The size of the critical current (which can be as large as 100 amperes in a 1-mm wire) depends on the nature and geometry of the specimen and is related to whether the magnetic field produced by the current exceeds the critical field at the surface of the superconductor. 

The effect is named after Francis B. Silsbee who studied conductivity at low temperatures.
