De Wielewaal, Beneden-Leeuwen. De Wielewaal () is a tower mill in Beneden-Leeuwen, Gelderland, Netherlands which was built in 1857 and is in working order. The mill is listed as a Rijksmonument.

History
De Wielewaal was built in 1857. It is similar in construction to Zeldenrust, Oss and De Nijverheid, Ravenstein. The three mills were probably built by the same millwright. In the 1930s, improvements were made to the mill. The speed of the millstones was increased by introducing smaller stone nuts. The mill was restored in 1967. In 1999, repairs were done to the sails and stage. The mill was sold to the Gemeente West Maas en Waal in 2002. It is listed as a Rijksmonument, No. 38428.

Description

De Wielewaal is what the Dutch call a "Stellingmolen". It is a six-storey tower mill with a stage. The stage is  above ground level. The cap is covered in dakleer. The sails are Common sails, which have a span of . They are carried on a cast iron windshaft. The windshaft also carries the brake wheel, which has 65 cogs. This drives a wallower with 32 teeth, which is situated at the top of the upright shaft. At the bottom of the upright shaft is the great spur wheel, which has 77 cogs. This drives a pair of  diameter Cullen millstones via a lantern pinion stone nut with 22 staves and a pair of  diameter French Burr millstones via a lantern pinion stone nut with 23 staves. A 1916 Brons diesel engine drives a pair of  French Burr stones and an electric motor drives a pair of  French Burr stones.

Public access
The mill is generally open on Sunday afternoon. or by appointment.

Glass-filled polymer. Glass-filled polymer (or glass-filled plastic), is a mouldable composite material. It comprises short glass fibers in a matrix of a polymer material. It is used to manufacture a wide range of structural components by injection or compression moulding. It is an ideal glass alternative that offers flexibility in the part, chemical resistance, shatter resistance and overall better durability.

Materials 
Either thermoplastic or thermosetting polymers may be used. One of the most widely used thermoplastics is a polyamide polymer nylon.

The first mouldable composite was Bakelite. This used wood flour fibres in phenolic resin as the thermoset polymer matrix. As the fibres were only short this material had relatively low bulk strength, but still improved surface hardness and good mouldability. 

A wide range of polymers are now produced in glass-filled varieties, including polyamide (Nylon), acetal homopolymers and copolymers, polyester, polyphenylene oxide (PPO / Noryl), polycarbonate, polyethersulphone

Bulk moulding compound is a pre-mixed material of resin and fibres supplied for moulding. Some are thermoplastic or thermosetting, others are chemically cured and are mixed with a catalyst (polyester) or hardener (epoxy) before moulding.

Applications 
Compared to the native polymer, glass-filled materials have improved mechanical properties of rigidity, strength and may also have improved surface hardness.

Compared to sheet materials 
Bulk glass filled materials are considered distinct from fibreglass or fibre-reinforced plastic materials. These use a substrate of fabric sheets made from long fibres, draped to shape in a mould and then impregnated with resin. They are usually moulded into shapes made of large but thin sheets.  Filled materials, in contrast, are used for applications that are thicker or of varying section and not usually as large as sheet materials.

Carl A. Wiley. Carl Atwood Wiley (December 30, 1918 – April 21, 1985) was an American mathematician and engineer. He is most widely known as the originator of the solar sail concept as well as the inventor of synthetic aperture radar.

Career
Wiley's research work began at the Air Force Aircraft Radiation Lab at Wright Field in 1941. In 1942 he discovered the piezoelectricity of Barium titanate, for which he later was awarded a patent. In 1949 he went to work as the engineer-in-charge of Goodyear Aerophysics. It was during this time he invented synthetic aperture radar in 1951, patented as "Pulsed Doppler Radar Methods and Means," #3,196,436. That same year Wiley posited the idea of solar sails in a science fiction story published in Astounding Science Fiction magazine entitled Clipper Ships of Space (originally titled Are the Clipper Ships gone forever?). Wiley wrote his story under the pen name of Russel Saunders, an in-group reference to Russel–Saunders coupling not unlike J.J. Coupling, itself a reference to angular momentum. Seven years later Richard L. Garwin developed the first technical specifications for a solar sail. Robert L. Forward credited Wiley for the genesis of the idea in Forward's 1990 patent.  Wiley's research and manuscripts for the story are now housed in the Eaton collection. In 1953 he left Goodyear to found his own company, Wiley Electronics in Phoenix, Arizona until it was bought out in 1962. Following that Wiley worked for North American Aviation and its successor, Rockwell International where he worked on various radar projects including LOCO, SINCO, VOLPHASE, and VOLFRE. In 1978 he went to work at Hughes Aircraft Company where he eventually retired as a chief scientist in the technology division of Hughes' Space and Communications Group. In 1985, IEEE awarded Wiley their Pioneer Award.

Michael J. Sailor. Michael J. Sailor is a nanotechnology researcher and professor at the University of California, San Diego. Sailor is best known for his research on porous silicon, a nanostructured material that is prepared by electrochemical corrosion of crystalline silicon wafers.

He pioneered the development of label-free biosensors from thin optical films of porous silicon. He prepared the first microparticles and nanoparticles of porous silicon, and harnessed the intrinsic photoluminescence of these formulations for in vitro and in vivo imaging applications. He was the first to demonstrate time-gated luminescence imaging with these nanoparticles, important because time-gating suppresses tissue autofluorescence that often compromises the fidelity of fluorescence images of biological tissues.  He also adapted the concept of "Smart Dust" to the field of nanotechnology: the idea that microscopic particles can be manufactured with optical, chemical, and mechanical properties that can perform sensing, signaling, and motive functions.

SIG KE7. The SIG KE7 is a light machine gun designed and manufactured in Switzerland in the decade before the Second World War. Although exported, it was never used by the Swiss Army.

Description
The SIG KE7 is a recoil operated, air cooled light machine gun with tilting bolt. It is fed from a curved box magazine mounted on the underside of the weapon, which holds 25 rounds. A light folding bipod is attached to the perforated barrel jacket, and an additional rear monopod can be fitted.

Notable feature of the gun is a very long travel of the bolt carrier (about 6 cm, 2.4 in) before it starts pulling the bolt back and extracting the fired case. It gives longer time for the pressure in barrel to drop for easier extraction.

History
The KE7 light machine gun was designed by Pál Király and Gotthard End at the SIG small arms factory in Neuhausen am Rheinfall. Production commenced in 1929, with most weapons being exported to the Republic of China chambered for 7.92×57mm Mauser ammunition. The Chinese government purchased 3,025 from Switzerland between 1928 and 1939, and the provincial government of Guangdong purchased 200 KE7s with 4,000 magazines in December 1928. In 1933, Liu Xiang funded Huaxing Machine Works' acquisition of machinery for a workshop in Chongqing. From 1933 to 1936, it would produce 6,000 KE7 copies. Three months after the war with Japan began, the workshop would be requisitioned by the Chinese government and produce ZB-26 copies after 1939.  

The KE7 would be used during the Chinese Civil War, the Second Sino-Japanese War and the Korean War. Some KE-7 machine guns were also made in other calibres for export to Latin America and Ethiopia. In 1930, examples were provided for trials being run by the British Army to find a replacement for the Lewis gun, although a modified ZB vz. 26 was finally adopted as the Bren gun.

Saxon VII T. The Saxon Class VII T were twin-coupled tank engines of the Royal Saxon State Railways designed for branch line (Sekundärbahn) operations. In 1925, the Deutsche Reichsbahn grouped these locomotives 1925 into their Class 98.70.

History 

The Royal Saxon State Railways grouped all 0-4-0T locomotives into their Class VII T. As well as several engines that came from nationalised railway companies, this class also included 43 units procured by the Royal Saxon Railways themselves.

Forty-two largely identical locomotives were delivered by the Sächsische Maschinenfabrik, formerly Richard Hartmann, to the city of Chemnitz in the period from 1882 to 1894. Initially they were classified as H VII T, but from 1896 just as VII T.

Common to the different delivery batches were driving wheel diameters of 1,130 mm and axle bases of 2,200 mm. The length of the locomotive and the height of the centre of the boiler above the rails were also identical on all models. The locomotives of the last two batches had a steam dome, whilst the older ones just had a Regleraufsatz.

In 1925, the Deutsche Reichsbahn took over 29 locomotives of this type. Five dated to 1882/83 (98 7051 – 98 7055), eleven to 1886 (98 7056 – 98 7066), nine to 1890 (No. 98 7067 – 98 7075) and four to the year 1894 (98 7076 – 98 7079). 

In 1931, no. 98 7069 became an industrial engine at the repair shop at Chemnitz, but was transferred to the Deutsche Reichsbahn fleet in 1951 as 98 7051. It was not decommissioned until 1967. Other long-serving engines were nos. 98 7065 and 98 7066 served until 1966.

The locomotive with number 98 7056 (formerly 1431 HEGEL) has survived. Until 1964 it belonged to the depot of Dresden-Altstadt and was then given to the Dresden Transport Museum. For many years it was part of their permanent exhibition. Today it has been stored in a museum depot in the old Bw Dresden-Altstadt and is maintained by the Dresden-Altstadt Depot Railway Museum.

H VII T (98 7031) 

Another engine built in 1889 by the Sächsische Maschinenfabrik with running number 1418 differed from the other H VII T stock in that it had a longer axle base (2,500 mm), larger coupled wheels and a higher top speed of 45 km/h. It also had a lower overall weight.

This locomotive also joined the Deutsche Reichsbahn fleet in 1925, as 98 7031. Until 1927 it was used as a shed loco in Bw Leipzig Hbf.

Counterweight brake. A counterweight brake () is an early form of hand brake on railway tenders and tank locomotives.

By throwing a counterweight lever, play in the brake blocks is quickly taken up and braking action is initiated. Further movement of the lever increases the transmission so that the blocks are pressed against the wheel tyres with greater and greater force.

On locomotive tenders the counterweight brake generally acts on all the axles, whilst on tank engines the braking action is only applied to the driving and coupled wheels.

Nongo-class warship. The Nongo class is a term used by the US Department of Defense to identify a series of new medium-size warships built by North Korea starting in the 2000s. Few such vessels are believed to be in service, but they appear to form the core of a modernized Korean People's Navy.

Features and design 
In late 1980s the North Korean shipbuilding industry experimented with a large warship with an innovative catamaran-hull design, the Soho-class frigate. After the 1990s, when the North Korean economy showed some signs of recovering after the great famine, the Korean People's Navy started introducing again this design to modernize its fleet of medium-size vessels.

North Koreans implemented the catamaran design, adopting Surface Effect Ship technology. The design is relatively advanced, and adopted by few Navies in the world. The first vessels of the class (the "pure" Nongo) appears to have also stealth lines. Considering the lack of official north Korean released data, most of features, design and details are speculations of analysts after observation of satellite pictures.

Weapons 
Weapons appears to be related with the different sub-classes, and different evaluations were given by analysts. The original stealth SES Nongo show only surface artillery weapons: a gun of  and a turret of  guns.

The missile boat variants at first were valued with one gun of , one or two turrets of 30 mm and unknown kind of anti-ship missiles.

Later, it surfaced after North Korean propaganda video that the missile boats are indeed armed with the relatively effective Russian Kh-35 missiles. Also the gun appears to be different, a reversed-engined turret of  (related probably to the Iranian Fajr-27, a reversed-engine gun of the famous Italian OTO Melara 76 mm).

Despite being probably less advanced than their South Korean rivals, the Nongo-class missile boats could on paper face the South Korean  sharing the same artillery (76 mm) and anti-ship missiles (even if the South Korean vessels are larger).

In January 2015 the first pictures of a vessel (of the stealth sub-class), employed in testing a reversed-engineered missile Kh-35, were released by KCNA.

Subclasses 
At least 3 subclasses are known:
 Original stealth SES
 "A" type missile boats (not-stealth, size reduced)
 "B" type missile boats (not-stealth, size reduced)

David L. Jones (video blogger). David L. Jones is an Australian video blogger. He is the founder and host of EEVBlog (Electronics Engineering Video Blog), a blog and YouTube channel targeting electronics engineers, hobbyists, hackers, and makers. His content has been described as a combination of "in-depth equipment reviews and crazy antics".

Life
Before becoming a full-time blogger, Jones worked on FPGA boards for the EDA company Altium.

According to Jones, he began publishing electronic design project plans in electronics DIY magazines like Electronics Australia in the 1980s. In recent years, several of his project articles appeared in Silicon Chip.

Jones is also the founder and co-host of The Amp Hour, an electronics engineering radio show and podcast.

EEVBlog
Jones' EEVBlog YouTube channel was created on 4 April 2009. The channel features in-depth equipment reviews and electronics commentaries. Jones has posted over 1000 episodes.

Batteriser incident
In a mid-2015 video, Jones disputed the claims of an unreleased battery life extender called Batteriser (later called Batteroo Boost after a lawsuit by Energizer). Batteroo, the company behind the product, disputed the arguments put forth by Jones and others, and published a number of demonstration videos in response. In the wake of Jones' video about Batteriser, his video was "disliked" by a torrent of IP addresses located in Vietnam. Other bloggers with related videos experienced similar activity from addresses in Vietnam. The bloggers involved have suspected that either a click farm in Vietnam was engaged to harm the reputations of those attacking the claims about the product, or that a single computer with many fake or stolen YouTube accounts utilized proxied IP addresses to cover its tracks. Due to the anonymous nature of the attacks, it remains unknown who was responsible.
