DFS SG 38 Schulgleiter. The Schneider DFS 108-14 SG-38 Schulgleiter (School glider) is a German high-wing, cable-braced, single-seat primary glider that was designed by Schneider, Rehberg and Hofmann at Edmund Schneider's factory at Grunau in 1938, hence the designation. It was produced by several builders, including Deutsche Forschungsanstalt für Segelflug (DFS).

Design and development
The SG 38 was designed to be a training glider for basic flight training by the Nationalsozialistisches Fliegerkorps (NSFK). The usual launch method was by bungee cord from a sloped hill. Because training was conducted solely by solo flight the aircraft had to be very easy to fly and also easy to repair.

The high-wing design uses a kingpost and cable bracing. The primary structure of the glider is of wood, with the wings, tail surfaces and inverted "V" kingpost all finished in doped aircraft fabric covering. The pilot sits on a simple seat in the open air, without a windshield.

The basic configuration was similar to earlier gliders such as the Stamer Lippisch Zögling and the Grunau IX, but the SG 38 was an entirely new design. Improvements included enlarged tail surfaces for better stability, a separate skid mounted on shock-absorbing springs, and an updated seat for the pilot.

Operational history

The SG-38 played a critical role in pilot training for the Luftwaffe in the Second World War, as a simple, but robust, trainer for the rapid increase in the number of pilots needed by Germany. It was commonly flown by bungee launch on the slopes of the Wasserkuppe and the hills of Saarmund. 

From 1949 to 1951 Spain's AISA produced 50 licence-built aircraft.

In the UK, Elliotts of Newbury built a copy of the SG.38 called the Elliotts Primary EoN; its version first flown in 1948 and used by the RAF as the Eton TX.1.

Haufe Dale Hawk 2. The Haufe Dale Hawk 2 is an American high-wing, strut-braced, single-seat glider that was designed and built by Walter Haufe and Leland Hanselman.

Design and development
The Dale Hawk 2 was named for Hanselman's home town of Dale, Wisconsin.

The aircraft was designed and built in 1939 and is constructed  from wood, with doped aircraft fabric covering. The two-spar wing is braced with "V" struts and employs a U.S.A. 35A airfoil. The wing has no spoilers or other glidepath control devices.

Operational history
In 1940 Haufe completed a nine-hour and fifty-minute flight over High Cliff near Neenah, Wisconsin flying the Dale Hawk 2.

Once the United States entered the Second World War at the end of 1941, the aircraft was put in storage, where it suffered some damage. It was purchased by C. M. Van Airsdale in 1954 and  restored by him with the assistance of Hanselman, Harry Edwards and C. Vogt. In 1969 Van Airsdale donated it to the EAA AirVenture Museum.

Caproni Ca.124. The Caproni Ca.124 was a 1930s single-engine Italian reconnaissance and bomber seaplane.

Design
The Caproni Ca.124 was a cantilever mid-wing monoplane of mixed construction. The fuselage was corrugated-skinned and the empennage cantilever and conventional, with the tailplane set at mid-fuselage.  The pilot's cockpit was forward of the leading edge.  It was a floatplane, mounted on metal floats each attached to the wings by pairs of N-form laterally orientated struts.

The Ca.124 was powered by a 900 hp (670 kW) Isotta Fraschini Asso XI.RC15, a water-cooled upright V-12 engine, supercharged to maintain power to 1,500 m (4,920 ft).  Bombs were contained within the fuselage, below the wing.

Hutchinson HS-127. The Hutchinson HS-127 is an American mid-wing  glider that was designed and built by Vernon Hutchinson.

Design and development
The HS-127 was designed and built by Hutchinson in 1956 as a single seat, V-tailed aircraft that incorporated spoilers mounted in the fuselage sides, above the wing roots. The aircraft was constructed from aluminium and employed a NACA 65 (3)-618 airfoil.

In 1960 Hutchinson constructed a new fuselage for the aircraft with two seats in tandem and a conventional tail. The wings from the earlier single seat fuselage were used on the new fuselage. The designer incorporated split trailing edge dive brakes and claims this was the first use of balanced trailing edge dive brakes. Both versions of the aircraft bore the same Federal Aviation Administration aircraft registration, N62P.

The aircraft's HS designation indicates Hutchinson Sailplane.

Operational history
Hutchinson completed his Silver badge and Gold badge while flying the HS-127 and also flew a number of  flights in it. In May 2011 the aircraft was still registered to Hutchinson, 55 years after its completion.

Riserless Light Well Intervention. Riserless Light Well Intervention (RLWI) enables the petroleum operators to increase the oil and gas recovery rate from subsea oil wells. The operation is performed through smaller dynamic positioned monohull vessels instead of larger mobile installations like traditional semisubmersible drilling rigs or drillships.

The RLWI enable subsea well intervention without having to use a drilling riser package connected to the subsea stack (blowout preventer system).

The technology is based on wireline well maintenance, where the cable is routed via a subsea lubricator system into the subsea well. Traditional activities are wireline operations for well logging, perforation, and installing or pulling equipment like plugs and downhole safety valve inserts. The operational envelope can be extended by use of tractors in horizontal wells.

The recovery rate has traditionally been considerably lower on a subsea well than for a surface platform well due more complicated well intervention and maintenance issues. RLWI enables the operators to perform intervention to increase the recovery rate at reduced time and cost.

There is a positive safety aspect by employing RLWI services as no hydrocarbons are transported to the vessel, but flushed back into the well through the lubricator system during normal operations. However, RLWI is a complex operation requiring special expertise and control in all phases of the preparation and implementation.

Lang & Witchell. Lang & Witchell was a prominent architectural firm in Dallas, Texas, active from 1905 to 1942.

History
Senior partner Otto H. Lang was born in Freiburg in 1864. He graduated in 1888 with a degree in structural engineering from the University of Karlsruhe, also studying architecture. He then relocated to the United States, eventually settling in Dallas, where he worked for the Texas and Pacific Railroad, eventually becoming its senior architect and engineer. Frank O. Witchell was born in South Wales in 1879. As a child, his family relocated to San Antonio, Texas. As a teenager he entered the office of J. Riely Gordon, one of the best-known architects in the state. In 1898 he began work as a designer with Sanguinet & Staats in Fort Worth.

In 1905, the two men separated from their employers, founding the new firm of Lang & Witchell. This firm would rise to become the most esteemed architectural firm in Dallas.

The partnership was dissolved in 1938, when Witchell retired duo to failing health. Lang continued to operate the firm until 1942, when he too retired. He continued on in an advisory capacity with architect Grayson Gill. Lang would die in 1947, and Witchell in 1952.

Legacy
The firm is credited with designing a number of buildings that are listed on the National Register of Historic Places.

Pascal Script. Pascal Script is a scripting language based on the programming language Pascal that facilitates automated runtime control over scriptable applications and server software. It is implemented by a free scripting engine that includes a compiler and an interpreter for byte code.

Pascal Script supports the majority of Object Pascal constructs, making it partly compatible to Delphi, Free Pascal and GNU Pascal.

Initially developed by Carlo Kok as CajScript and renamed to Innerfuse Pascal Script with version 2.23, the software was taken over by RemObjects, renamed again to RemObjects Pascal Script and offered as open source software for the Delphi IDE. Beginning with version 2.07 CajScript has been ported to Free Pascal. Since 2017 Pascal Script is included as a standard component in the Lazarus IDE.

Software using Pascal Script
Pascal Script can be used by installer scripts for Inno Setup, an open source setup engine. Using Pascal Script may provide additional flexibility during installation and uninstallation, e. g. by adding new wizard pages, calling DLLs and providing custom behaviour and install conditions.

Pascal Script is also used for server-side scripting in Pascal Server Pages and maXbox, a scripter studio with an inbuild Delphi engine.

ReNamer, a batch-oriented automated file renaming tool for Windows, can be expanded by Macros written in Pascal Script.

With the release of version 1.2, the Lazarus IDE began to include the Pascal Script engine, which is now available in form of several components. Additionally, some of Lazarus' standard packages including SynEdit and TAChart support Pascal Script, and the IDE may be extended by using macros written in Pascal Script.

Increasingly reported applications of Pascal Script in Science and Technology include SCADA, robotics and education.

History
Pascal Script started out in 2000 with CajScript 1.0, which was soon superseded by CajScript 2.0 (later called Innerfuse Pascal Script 2.0).

Version 2.0 interpreted scripts while it ran them, which had the disadvantage that every piece of code had to be reparsed every time the script engine went over it.

With Pascal Script 3.0, this was changed to a new model, where the compiler and runtime were completely separated from each other and used a custom byte code format to represent the compiled script. This compiled script only contained the bare minimum that was required to execute the code.

Later, when Carlo Kok joined RemObjects, it was renamed RemObjects Pascal Script and is now being maintained by RemObjects Software. A fork of Pascal Script is maintained in the sources of the Lazarus IDE. The Lazarus and Free Pascal teams ported PascalScript from Intel processors to additional architectures including PowerPC and ARM.

Moss bioreactor. A moss bioreactor is a photobioreactor used for the cultivation and propagation of mosses. It is usually used in molecular farming for the production of recombinant protein using transgenic moss. In environmental science moss bioreactors are used to multiply peat mosses e.g. by the Mossclone consortium to monitor air pollution.

Moss is a very frugal photoautotrophic organism that has been kept in vitro for research purposes since the beginning of the 20th century.

The first moss bioreactors for the model organism Physcomitrella patens were developed in the 1990s to comply with the safety standards regarding the handling of genetically modified organisms and to gain sufficient biomass for experimental purposes.

Functional principle 
The moss bioreactor is used to cultivate moss in a suspension culture in agitated, and aerated liquid medium. The culture is kept under lighting with temperature and pH value held constant. The culture medium—often a minimal medium—contains all nutrients and minerals needed for growth of the moss.

To ensure a maximum growth rate, the moss is kept at the protonema stage by continuous mechanical disruption, e.g. by using rotating blades. Once the density of the culture has reached a certain threshold, the lack of nutrients and the increasing concentration of phytohormones in the medium triggers the differentiation of the protonema to the adult gametophyte. At this point the culture has to be diluted with fresh medium if it is intended for further use.

According to the intended yield, this basic principle can be adapted to various types and sizes of bioreactors. The cultivation chamber can, for example, consist of a column, a tube, or exchangeable plastic bags.

Production of biopharmaceuticals 
Various biopharmaceuticals have already been produced using moss bioreactors. Ideally, the recombinant protein can be directly purified from the culture medium. One example for this production method is factor H: this molecule is part of the human complement system. Defects in the corresponding gene are associated with human diseases such as severe kidney and retinal disorders. Biologically active recombinant factor H was produced in a moss bioreactor for the first time in 2011. The enzyme alpha-galactosidase now is allowed to be produced in moss bioreactors by the German Federal Institute for Drugs and Medical Devices. It will be tested as enzyme replacement therapy in the treatment of Fabry's disease. The clinical trial phase 1 was completed in 2017.
