Laird LC-EW. The Laird LC-EW was a six seat cabin sesquiplane designed for the industrialist George Horton. It first flew in 1934.

Design and development

Many Laird aircraft were designated as LC (Laird Commercial). In most cases this was followed by an airframe code, here E and an engine code, here W for Wasp. The LC-EW was designed to an order from the industrialist George Horton, who had previously owned the sole Laird LC-AA, first flown in 1928.

It was a true sesquiplane, with a lower wingspan slightly less than half that of the upper. Both wings were essentially rectangular in plan out to rounded tips. The upper wing was built around spruce spars with plywood ribs and fabric covered. Upper and lower wings were braced together with parallel pairs of wide spread, transverse, streamlined V-struts on each side. Their apices on the lower wing were immediately above the landing legs. Between the fuselage and the legs the lower wing was constructed of Cr/Mo steel tubing and aluminium alloy-skinned; beyond, its structure was the same as that of the upper wing. Aluminium alloy ailerons were hinged only on the upper wings, filling about half the span. The inner lower wing carried flaps of similar construction. Both upper and lower wings contained fuel tanks.

The LC-EW was powered by a , nine cylinder Pratt & Whitney Wasp C radial engine driving a two-bladed propeller and tightly enclosed under a long chord, NACA cowling, though bumped out over the rocker boxes to reduce its diameter. Aft, the fuselage was an all-metal aluminium alloy structure with multiple frames, stiffeners and metal skin. The pilots, or pilot and fifth passenger, sat side by side at the front of the cabin and had dual controls, including a central Y-type control column. Radio was fitted, with an external aerial. The ventilated, heated cabin had three windows on each side and was entered by a starboard-side door; its four passenger seats had safety belts. There was a baggage compartment and toilet at the rear. At the rear the tail was conventional with its cantilever tailplane at mid-fuselage. The tail surfaces were all metal constructions, similar to the fuselage. The tailplane had a blunted triangular profile and carried blunted rectangular elevators. Fin and unbalanced rudder had similar profiles to the horizontal tail plans.

Its fixed, conventional landing gear, with a track of , had short, vertical oleo legs encased in fairings at the ends of the inner section of the lower wings. Each had a pneumatically-tyred wheel, also under a fairing. The castoring tail wheel was also on an oleo strut.

Operational history

Little is known about its short history in Horton's ownership. He died in 1935 and the LC-EW was bequeathed to the aeronautical department of the  Rensselaer Institute.

Isotope (catamaran). The Isotope is an American catamaran sailing dinghy that was designed by Frank Meldau as a one-design racer and first built in 1962.

The design is the larger stablemate of the Cheshire 14 catamaran.

Production
The design is built by Fiberglass Unlimited (now called Custom Fiberglass International) in Wake Forest, North Carolina, United States. A total of 710 have been built and the design remains in production.

Design
The Isotope is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig, with aluminum spars, a sealed rotating mast and fully battened mainsail, with eight ash wood or fiberglass battens. The hulls have spooned raked stems, vertical transoms, transom-hung, kick-up rudders controlled by a tiller and retractable, self-tending centerboards. The hulls are joined with three cross-members. There are two stowage compartments, with hatches. The boat displaces  and has flotation for positive buoyancy, plus a righting bar.

The boat has a draft of  with the centerboards extended and  with them retracted, allowing beaching or ground transportation on a trailer.

For sailing the design may be equipped with options such as a mast limiter, roller furling jib and a trapeze.

The design has a Portsmouth Yardstick racing average handicap of 74.0. It is normally raced with a crew of one sailor although it can carry three people.

Operational history
In a 1994 review Richard Sherwood wrote, "sister to the Cheshire, the Isotope is two feet longer and five
Portsmouth numbers faster."

Hexafluorobutadiene. Hexafluorobutadiene is an organofluorine compound with the formula (CF2=CF)2.  A colorless gas, it has attracted attention as an etchant in microelectronics.  It is the perfluoroanalogue of butadiene.

It can be prepared by coupling of C2 compounds such as from chlorotrifluoroethylene or bromotrifluoroethylene. Routes from C4 species have also been demonstrated.  For example, an early synthesis involved Zn-induced dechlorination of 1,2,3,4-tetrachloro-1,1,2,3,4,4-hexafluorobutane.

Hexafluorobutadiene dimerizes via a [2+2] process at 150 °C to give perfluorinated divinylcyclobutanes.

Schleicher AS 34Me. The Schleicher AS 34Me is a German glider manufactured by Alexander Schleicher. It is a self-launcher that uses an electrical propulsion system.

Design and development 
The AS 34Me is a single-seat, mid-wing sailplane of composite construction, with a retractable monowheel landing gear and a T-tail. The design is based upon the ASW 28, with an unflapped wing. It can be flown with an  span and  area or a  span and . The power unit has already been used in Schleicher ASG 32 EI, except the batteries are mounted in the wings rather than the fuselage.

The AS 34Me has an air-cooled EMRAX motor with 35 kW maximum and 25 kW continuous power output and a completely retractable propeller, unlike front electric sustainer (FES) units used on gliders such as the Schempp-Hirth Ventus-3. The battery has a capacity of 8.6kWh. The manufacture claims a maximum rate of climb at take-off of 3.7 m/s (728 ft/min). The remaining propulsion capacity after a take-off to 600 m (with a gross weight of 477 kg) will provide a further rate of climb of 2.5 m/s (492 ft/min) to an altitude of 2200 m (7200 ft) and a range of 125 km (77 mi) using a "climb and glide" method. The glider can be flown in the Standard class or in the 18 metre Class.

Abinsk Electric Steel Works. Abinsk Electric Steel Works is a manufacturer of metallurgical products with production premises located in the city of Abinsk, Krasnodar Krai (Russia).

History 

The factory's cornerstone ceremony was held in Abinsk in 2007. The Rolling Mill was launched in July 2010. Construction of the Meltshop with an annual capacity of 1.3 million tons of metal (Stage 2) started in 2011. The project was successfully completed in 2013. At the same time, the Lime Shop was put into operation together with the Meltshop.

The launch of own oxygen production facility (in 2015) made a manufacturing complex more autonomous. The Meltshop produced their 1st million ton of steel in November 2015. The 2nd Rolling Mill was launched in May 2016. That same year, an official ceremony of laying the cornerstone of the Hardware Shop (4th stage of the factory) was held in attendance of Mr. V. I. Kondratiev, Head of the Krasnodar Krai Administration. The shop was put into operation on 20 March 2019. In 2016, there was opened a Training Center with the state license to render educational services in vocational professions. The Meltshop produced 140,224 tons of section billets in August 2018.

Company structure 

The factory consists of five production facilities (steelmaking, rolling, hardware, oxygen, and lime production) that are interconnected within the same technological chain. Infrastructure workshops and factory management departments are also part of the factory. The AESW Meltshop's annual output is about 1,500,000 tons of steel.

Currently, the Shop performs smelting and casting of different steel grades. The Rolling Mill production includes large and small rolled products as well as wire rods. Its annual production capacity is about 1,100 tons of rolled products. The AESW's hardware production line operates in the Steel Wire Shop with an annual production capacity of 85,000 tons of steel wire. Annual production capacity of the AESW's Oxygen Plant is 110,000 tons of liquid oxygen. In addition, the company produces liquid argon (5,600 tons per year) and nitrogen (4,500 tons per year).

Results 

In 2018, the Abinsk Electric Steel Works' revenue was RUB 29,39 billion. As a result, the company was ranked top 10 among the industrial companies in the Krasnodar Krai (3rd according to the RBC rating). That same year, the AESW exported nearly RUB 20 billion in goods.

In 2019, the AESW acquired the Balakovo Steel Factory from the Severstal. The said factory is located in the Saratov region, and they mainly focus on the manufacture of rebar for the construction sector, as well as on the manufacture of angle bars and channel bars.

Schönhagen Airport. Schönhagen Airport ()  is a general aviation airport near Trebbin, a town in the German state of Brandenburg. It is located approximately  southwest of Berlin.

History

Since 1928 the area around Löwendorfer Berg has been used for gliding. The Luftwaffe der Wehrmacht, which expanded the area from 1936, used Trebbin Air Base as an emergency landing site, no flying units were stationed there. Between 1937 and 1945 a "Reichsschule für Segelflug" of the National Socialist Flyers Corps which operated gliding in Schönhagen, was located at Schönhagen..

In GDR times the site was home to the school combine named "Ernst Schneller" of the Gesellschaft für Sport und Technik which among other things provided basic pilot training in preparation for military pilot training with the NVA. On 31 January 1952 Karl Liebeskind performed the first take-off of an aircraft in the GDR with a SG 38 in Schönhagen.

After the fall of the Iron Curtain, the airfield was and is being continuously expanded. Both runways were asphalted, the main runway was extended and equipped with a navigation light system.

On 24 November 2008, the last aircraft taking off from Tempelhof landed in Schönhagen

Facilities
The airport is licensed for aeroplanes up to  maximum takeoff weight. It has one runway designated 07/25 with an asphalt surface measuring , one runway designated 12/30 with an asphalt surface measuring  and one runway designated 12/30 with a grass surface measuring .

Abraham Ginzburg. Abraham Ginzburg (Hebrew: אברהם גינזבורג) (1926–2020) was a Professor Emeritus of Computer Science. He served as Vice President of the Technion Institute, and President of the Open University of Israel.

Biography

Ginzburg was born on 1 August 1926 in Navahrudak, Belarus. He began acquiring his education during World War II, after which he taught the children of Sh'erit ha-Pletah mathematics. In 1949, Ginzburg immigrated to Israel, and began studying in the Technion Faculty of Electrical Engineering, where he received his BSc summa cum laude. Three years later, he acquired a Master's degree in electrical engineering and in 1959, he received his PhD in mathematics, and was appointed lecturer in the Faculty of Mathematics of the Technion.

During 1965–1967, he served as a visiting lecturer in Carnegie Mellon University, in Pittsburgh, Pennsylvania. Upon returning to Israel in 1967, he was appointed associate professor of Mathematics in the Technion Institute, and in 1971 to a professor of Computer Science. Ginzburg founded the Department of computer science in the Technion, and served as its first head of department. Later, he served as the vice president of development of the Technion.

In 1976, Ginzburg took part in the formation of the Open University of Israel, as its vice president, and from 1977 until 1987 served as its president

Ginzburg received an Honorary degree from the UK Open University in 1988, an Honorary PhD from the Weizmann Institute in 1990, and, in 2002 was awarded a Rotary Prize for the promotion of higher education in Israel.

Ginzburg was married to Pnina, and was a father of five.

Research 
Ginzburg completed his PhD in mathematics in the year 1959. The thesis title was "Multiplicative Systems as Homomorphic Images of Square Sets", and was done under the supervision of Prof. Dov Tamari.

During the early '60s, Ginzburg was involved in research in basic group theory, graph theory and automata, and frequently collaborated with Michael Yoeli.

In 1961, Ginzburg, in collaboration with Paul Erdős and Abraham Ziv, proved the Erdős-Ginzburg-Ziv Theorem. This Theorem is an important result in Abelian group theory, and is cited to this day.

In 1968, Ginzburg published his book "Algebraic Theory of Automata".

Ginzburg also invested a lot of time in writing several Textbooks in mathematics, for high school and first degree Mathematics and Engineering students.

Leeward 16. The Leeward 16 is an American sailing dinghy that was designed by Luger Industries and first built in 1962.

Production
The design was built by Luger Industries in Burnsville, Minnesota, United States starting in 1962. The company produced it as a kit boat for amateur construction, which the building time estimated at 10–15 hours. The company went out of business in 1987 and the boat is now out of production.

Design
The Leeward 16 is a recreational sailboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with anodized aluminum spars. The hull features a spooned raked stem, a conventional transom, a rounded, transom-hung rudder controlled by a tiller and a retractable centerboard. It displaces  and has an angular cuddy cabin for stowage.

The boat has a draft of  with the centerboard extended and  with it retracted. With the non-folding rudder removed it has a draft of , allowing beaching. Ground transportation on a trailer is facilitated by a hinged tabernacle that permits easy lowering of the mast by easing the forestay.

A motor mount was a factory option, allowing fitting a small outboard motor of  for docking and maneuvering. Other factory options included sails, trim molding and
running lights for night operation. Foam for hull buoyancy was recommended to make the boat unsinkable.

For sailing the design is equipped with mainsail roller reefing around the boom. The jib sheets, mainsheet and the centerboard raising and lowering lines are all controlled from the cockpit. The supplied assembly kit included stainless steel and anodized aluminum fittings.

The design has a Portsmouth Yardstick racing average handicap of 112.3 and is normally raced with a crew of two sailors.

Operational history
In a 1994 review Richard Sherwood wrote, "Luger Industries buil[t] kit boats [that] rang[e] in length from 8 feet
to 30 feet. The Leeward 16 is typical."

Sailrite describes the design, "the Luger Leeward 16 has plenty of cockpit space for the family and enough room in the small cuddy cabin for a picnic basket and cooler. With a modest sail plan the Luger Leeward 16 is an excellent boat for those learning to sail."
