Lanzhou–Hezuo railway. The Lanzhou–Hezuo railway or Lanhe railway ( or ) is a railway line under construction that will connect Lanzhou to Linxia and Hezuo by rail. It is proposed to continue the line from Hezuo to Chengdu. The railway line will be the first railway to be constructed in Linxia and Gannan.

The length of the line will be  of which  is newly constructed.

Although an existing railway connects Lanzhou to Yongjing, the new Lanhe railway will follow a different route.

History
The initial feasibility study was presented in 2009. In 2011, the Ministry of Railways requested a technical study for the railway, this was completed in 2013. Construction started in December 2014 and was originally planned to be completed in 2019. However, the designs were adjusted and construction was suspended. In 2015, it was announced that the design speed was increased to 120km/h to 200km/h, and a new feasibility study was to be completed by 2016.

In 2019, it was announced that the construction would resume by the end of the year. Construction is by the China Railway Bureau 20th Construction Group at a total investment of CNY 22.987 billion.

Osstell AB. Osstell AB is a company headquartered in Gothenburg, Sweden that develops, manufactures, and sells devices and accessories used to measure dental implant stability. It was founded in 1999 with the aim of developing and commercializing a device that utilized resonance frequency analysis (RFA) to determine the level of stability of a dental implant.

Patented technology 
In a dental implant procedure, a hole is drilled into the jawbone and a titanium implant is inserted. If and when the implant has proven to be stable in the jawbone, a prosthetic tooth is then affixed to the implant.

Osstell's patented RFA device (the most recent generation called Osstell IDx) helps dentists assess the stability of the implant, without having to physically disturb it. A small aluminum rod, called a SmartPeg, is placed in the implant. The RFA device prompts vibration in the rod by initiating magnetic pulses of varying frequencies. The RFA device detects the resonance frequency of the rod (called SmartPeg) while attached to the implant. The resonance frequency is converted to a numeric scale from 1 to 100, with higher numbers indicating higher stability.

This scale, called the Implant Stability Quotient (ISQ), corresponds with the kHz frequency range of 3500–8500 kHz. The ISQ scale was developed by Osstell in order to give an immediately comprehensible indicator of implant stability and is now the global standard for implant stability measurement.

The instruments are manufactured in factories in Kungsbacka and Vänersborg, Sweden.

Cardboard Crash. Cardboard Crash is a 2015 National Film Board of Canada (NFB) mobile app and virtual reality work developed by Vincent McCurley, exploring the ethical issues of autonomous cars. 

Produced for the NFB in Vancouver by Loc Dao, Cardboard Crash explores the ethical consequences of self-driving car algorithms and how should they be chosen. It presents users in a scenario where they are driving with a child in the vehicle and a road incident presents them with three alternative actions: veering left and colliding with a family, driving into a truck, or turning right, off a cliff. The accident-in-progress is slowed down to bullet time, as users are forced to make the choices a computer might have to make, with no ideal solution. 

Cardboard Crash was selected to the 2015 DocLab program at the International Documentary Film Festival Amsterdam as well as the New Frontier section of 2016 Sundance Film Festival. In April 2016, it received the Webby Award for Online Film & Video/ VR: Gaming, Interactive, or Real-time (Branded), as The NFB’s Cardboard Crash VR for Google Cardboard. In November 2016, it received the award for Best Mobile Entertainment at the Digi Awards.

John Fox (railway engineer). John Fox,  (1924 – 2001) was a Canadian civil engineer. He oversaw the Mount Macdonald Tunnel project at Rogers Pass in the Canadian Rockies, the crowning achievement of a 40-year career at Canadian Pacific Railway. The innovative 1.2 km John Fox Viaduct, just to the east of the Mount Shaughnessy Tunnel eastern portal is named after him.

Early life
Son of James Fox who came from England and operated a store in Huntingdon, Quebec, John Fox attended Huntingdon Academy and later joined the Royal Canadian Air Force as a pilot in World War II. After the war, he studied Civil Engineering at McGill University and married the former Janet Fraser of Dundee, Quebec in 1949, the same year that he joined the CPR.

Legacy
John Fox was appointed to the Order of Canada on October 25, 1990, with the following citation: "Vice-President of Engineering and Special Projects at Canadian Pacific Rail, he was responsible for introducing innovative and environmentally-sensitive engineering techniques in the construction of the Roger's Pass Project, the single most important railway project since the building of the main line. His leadership and professionalism have facilitated the enhancement of the safety and efficiency of Canada's railway system".

Les Aventures électriques de Zeltron. Les Aventures électriques de Zeltron is an educational children's television series broadcast on Antenne 2's Récré A2 program in France and TVJQ in Quebec, Canada. The show was sponsored by Électricité de France (EDF) and was produced from 1979 to 1982. The companies D-3-mil and CIP Vidéo worked on the show and the staff included Marcel Dupouy.

The show features an extraterrestrial named Zeltron (voiced by Michel Elias), who resembles a small greeninsulator with orange limbs and a bolt on top of his blue head, as he teaches electricity-related subjects and history. Some episodes include his adventures and conversations with Jo and Jessie, a boy and girl living on Earth. Episodes end with a question the viewer can answer through postcard. Another character is the robot Voltix.

In the show's production, Zeltron and Voltix are marionettes with different colors than they appear in the show. A process was used to achieve cartoon-like visuals for the two characters. Early in the show's run, the backgrounds were illustrated before switching to reel footage.

The character Zeltron was created by François Castan and made earlier appearances at the Salon de l'enfance and Les Visiteurs du mercredi in 1978. Zeltron was merchandised through products such as comics published by GP, plastic figurines, and a key ring of Zeltron with movable eyes. According to Yves Bouvier of the University of Savoy, Zeltron was the most successful EDF effort at teaching the concepts of electricity and promoting its brand towards children.

Electrical and Plumbing Industries Union. The Electrical and Plumbing Industries Union (EPIU) was a trade union representing engineers, plumbers and related workers in the United Kingdom.

The union was founded in 1988 as a split from the Electrical, Electronic, Telecommunications and Plumbing Union (EETPU).  That year, the EETPU was expelled from the Trades Union Congress (TUC) for making agreements with companies that it would be the only trade union they recognised, against the opposition of other TUC members.  Around 5,000 members of the EETPU were determined to remain within the mainstream trade union movement and left to form the EPIU, under the leadership of John Aitkin.

The EPIU initially had no structure and was unable to represent its members, or even accept their membership payments.  As a result, five other unions represented its membership, on a temporary basis.  Only in 1991 was the union put on a sound basis, recognised by the Trade Union Certification Officer and accepted into the TUC.  It established an office at Park House on Wandsworth Common.

In both 1991 and 1993, the EPIU attempted to join the National Engineering Construction Committee.  It was supported by the GMB, Manufacturing, Science and Finance and Transport and General Workers' Union (TGWU), but opposed by the Amalgamated Engineering and Electrical Union, into which the EETPU had merged, and also by employers' organisations.

In 1995, the EPIU merged into the Transport and General Workers' Union.

Sebkha Kelbia. The Sebkha Kelbia (سبخة الكلبية) is an intermittent lake in Tunisia that covers 8000 hectares in Sousse Governorate, at 35°50'34"North,  10°16'18"East,  south of Kondar.

Considered the second most important wetland in the country after lake Ichkeul, it is classified a nature reserve by decree of the Ministry of Agriculture of 18 December 1993. The Oued Nebhana, Oued Merguellil and Oued Zeroud rivers flow into the dry lakebed during rainfall season, but are now controlled by dams protecting the plain against the floods. The dams coupled with the operation of large agricultural irrigation schemes have had an environmental impact on the sebkha, which has not been studied to date. The agricultural population living around Sebkha Kelbia is estimated at 23,000 people.

Kinetic class (virology). A kinetic class, also known as a temporal class, is a grouping of genes in a viral genome that are expressed at the same time during the viral replication cycle. Five of the human DNA viral families have multiple kinetic classes: Poxviridae, Herpesviridae, Adenoviridae, Papillomaviridae, and Polyomaviridae. All of the genes in a particular kinetic class are activated by the same mechanism: either by the process of the virus entering the cell and uncoating, or by the products of an earlier kinetic class in what is known as a transcriptional cascade. Generally speaking, earlier kinetic classes code for enzymes that direct the viral replication process, and later kinetic classes code for structural proteins to be packaged into virions

Viruses with three kinetic classes: Poxviridae, Herpesviridae, and Adenoviridae 
Multiple naming schemes exist in virus families that have three kinetic classes; some refer to the three classes as 1) immediate-early 2) early and 3) late, and some refer to these same classes as 1) early 2) intermediate and 3) late. The former naming scheme is adopted below because it emphasizes the relative similarity in function of the first two classes compared to the third.

Immediate-early class 
The first genes expressed, in the immediate-early class, prepare the virus for replication and protect it from host defenses. These genes are activated in Poxviruses by enzymes packaged in the virion itself. They are responsible for dissolving the virion capsid, directing DNA replication (in Poxviruses), protecting the virus from the host's interferon and complement defenses (in Poxviruses), and activating the early class of genes.

Early class 
The second class of genes continues to combat host defenses, stimulates DNA replication (in Herpesviruses), and activates the late class. In Herpesviruses, the early class is known as the beta class and replicates the DNA genome starting from three different origins of replication. In Adenoviruses, it consists of two transcription units, IVa2 and IX.

Late class 
The late class consists primarily of structural proteins and assembly enzymes, and is dependent in all three families on the prior synthesis of viral DNA copies. In Herpesviruses, for example, the late class consists of gamma-1 and gamma-2 genes. After the late class is expressed, the virions can assemble and exit the cell.

Viruses with two kinetic classes: Papillomaviridae and Polyomaviridae

Early class 
The early proteins produced in Papillomaviruses and Polyomaviruses regulate the cell cycle and activate DNA replication. In Papillomaviruses, they are called E1 through E7 and also stimulate cellular replication. In Polyomavirus, the early proteins are T antigens.

Late class 
The late proteins make up the virus capsid. In Polyomaviruses, they are known as VP1, VP2, and VP3; in Papillomaviruses they are called L1 and L2 (for “late”).

Remington Model 783. The Remington Model 783 is a civilian bolt action hunting rifle built by Remington for the budget market. The rifle was launched in 2013 (which is where the "3" in 783 originates) and is considered a spiritual successor to the Remington Model 788 (which is where the "78" in 783 originates).

The mechanical design of the Model 783 is based upon the Marlin X7 rifle that was acquired by Remington in 2007. No parts are shared with the more expensive Remington Model 700 rifle.

Design
The rifle has innovative design features such as an adjustable trigger with finger safety in the trigger blade. Adjustment of the trigger pull is possible within 2.5 to 5 lbs. The floating bolt head and barrel-retaining nut, features pioneered by Savage in the models 340 (barrel nut), introduced in 1950, and the 110 bolt action (floating bolt head), introduced in 1958, are well-established and successful design elements. The black synthetic stock is made from plastic with a high nylon content making it more rigid than other budget stocks. To reduce the felt recoil a gel filled pad is used. For improved accuracy, the barrel is free floated and the action is pillar bedded. The small ejection port makes the receiver very rigid.

The detachable box magazine is made from a metal frame and carries 3-5 rounds depending on the cartridge. The carbon steel barrel is button-rifled and is available in lengths between 20 and 24" depending on the caliber. There are both long and short receivers available depending on the cartridge.

The bolt has forward dual-opposed lugs and is released from the receiver using a lever on its left side, the bolt can be removed with the safety on.  The two position safety is located on the right side of the bolt and maneuvered with a thumb lever. On top of the receiver is four mounting holes for scope rails.

In 2017, the Model 783 was available with a new walnut stock and packaged with a 3-9x40 scope. This version also has screw-in swivel studs that allows for a bipod to be mounted on the stock.

Cartridges
The Model 783 has been offered in the following calibers:

Reception
The Model 783 has received many positive reviews and is considered a good beginner's rifle. It has received praise for its accuracy and price, but criticism for its plastic feel.

YbBiPt. YbBiPt (ytterbium-bismuth-platinum; also named YbPtBi) is an intermetallic material which at low temperatures exhibits an extremely high value of specific heat, which is a characteristic of heavy-fermion behavior. YbBiPt has a noncentrosymmetric cubic crystal structure; in particular it belongs to the ternary half-Heusler compounds.

Discovery
YbBiPt was discovered by Zachary Fisk (Los Alamos National Laboratory) and coworkers in 1991 in the context of material research devoted to correlated electron systems such as heavy-fermion metals and Kondo insulators. 
Then the material was studied in detail due to its unconventional properties at very low temperatures (below 1 K).

Material properties
YbBiPt crystallizes in the MgAgAs structure, which is also known as the half-Heusler structure. YbBiPt exhibits metallic behavior, e.g. continuously decreasing electrical resistivity upon cooling. The temperature dependence of the specific heat shows an anomaly at 0.4K and linear behavior at yet lower temperatures with the enormous Sommerfeld coefficient (which describes the linear-in-temperature contribution to the specific heat caused by metallic electrons) of 8J/(mol Yb K2), which indicates an effective mass of the charge carriers that is extremely large even for heavy-fermion standards.

Larger context
The crystal structure of YbBiPt makes it an example of the Heusler compounds, more precisely of the so-called half-Heuslers which have XYZ composition. In recent years, there has been a large interest in this material class due to the large variety of physical properties that can be found, and many new Heusler materials have been discovered.
