2015 Indian Border Security Force King Air crash. On 22 December 2015, a light aircraft of the Indian Border Security Force crashed within the grounds of Indira Gandhi International Airport in Delhi, India. Ten personnel of the Border Security Force, three officers and seven senior technicians, were killed. The 22-year-old Beechcraft B200 King Air took off for Ranchi just before 9.30am, before crashing shortly afterwards.

Aircraft 
The aircraft involved in the accident was a 22-year-old Beechcraft B200 King Air.

Passengers and crew 
The plane has two pilots, each with a commercial pilot licence.

In addition to the pilots, the plane was carrying eight technicians to Ranchi to repair a helicopter.

Accident 
After the aircraft's engines were started the crew reported that there was a problem (the nature of which has not been reported), but continued with the flight after receiving advice from ground staff. The aircraft took off at 9:27am local time with an expected arrival time at Ranchi of 12:00pm.

Soon after taking off, the crew informed air traffic control that something was wrong and that they would return to Delhi. The pilots were then cleared to make an emergency landing on Delhi's Runway 28. At 9:40 AM, contact was lost with the aircraft. The plane then veered to the left, narrowly missing a village. It brushed a tree before hitting the perimeter wall of the airport and crashed into a sewage treatment plant within the airport complex. The aircraft then caught fire and was destroyed. All ten occupants were killed and another on the ground was injured.

Cause 
The cause can be attributed to pilot error who incorrectly activated the autopilot and failed to take the proper corrective action. Five recommendations are also made.

Comparison of programming languages by type system. This is a comparison of the features of the type systems and type checking of multiple programming languages.

Brief definitions
 A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
 A structural type system means that the language decides whether types are compatible and/or equivalent based on the definition and characteristics of the types.
 Type checking determines whether and when types are verified. Static checking means that type errors are reported based on a program's text (source code). Dynamic checking means that type errors are reported based on a program's dynamic (run-time) behavior.

ALFLEX. ALFLEX (Automatic Landing Flight EXperiment) was an experimental unmanned aircraft created by NASDA and NAL, the predecessors of JAXA, in 1996. It was built as a successor to HYFLEX as part of the HOPE program.

ALFLEX was built to establish the basic technology of automatic landing. The design featured a streamlined metal hull, delta planiform wings, and large winglets. Despite being a project of Japanese aerospace agencies, ALFLEX never left the atmosphere. Instead, it was carried up to a high altitude by a helicopter, then released to automatically glide down to the designated landing site, navigating by means of onboard computers. ALFLEX completed thirteen drop tests from July to August 1996, all of which were successful.

Specifications (ALFLEX) 
 Length (without pitot boom): 6.10 m
 Wingspan: 3.78 m
 Height (without gear): 1.35 m

Rolling release. Rolling release, also known as rolling update or continuous delivery, is a concept in software development of frequently delivering updates to applications. This is in contrast to a standard or point release development model which uses software versions which replace the previous version.  An example of this difference would be the multiple versions of Ubuntu Linux vis-à-vis the single and constantly updated version of Arch Linux.

A rolling release model should not be confused with a staged or "staggered" rollout, in which an update is gradually made available to an increasing percentage of users for testing or bandwidth reasons.

Model
Rolling release development models are one of many types of software release life cycles. Although a rolling release model can be used in the development of any piece or collection of software, it is most often seen in use by Linux distributions, notable examples being GNU Guix System, Arch Linux, Gentoo Linux, openSUSE Tumbleweed, PCLinuxOS, Solus, SparkyLinux, and Void Linux. Some modern Distributed SQL databases such as YugabyteDB also support this feature.

A rolling release is typically implemented using small and frequent updates. However, simply having updates does not automatically mean that a piece of software is using a rolling release cycle; for this, the philosophy of developers must be to work with one code branch as opposed to discrete versions. When the rolling release is employed as the development model, software updates are typically delivered to users by a package manager on the user's personal computer, accessing through the internet a remote software repository (often via a download mirror) stored on an internet file server.

Methylphosphine. Methylphosphine is the simplest organophosphorus compound with the formula CH3PH2, often written MePH2.  It is a malodorous gas that condenses to a colorless liquid. It can be produced by methylation of phosphanide salts:
KPH2  +  MeI   →   MePH2  +  KI

Reactions
The compound exhibits the properties characteristic of a primary phosphine, i.e., a compound of the type RPH2.  It can be oxidized to methylphosphonous acid:
MePH2  +  O2  →   MeP(H)O2H
It protonates to give a phosphonium ion:
MePH2  +  H+  →   MePH3+
With strong bases, it can be deprotonated to give methylphosphanide derivatives:
MePH2  +  KOH  →   K[MePH]  +  H2O

Inverterization. Inverterization is the process of using an inverter-based motor drive intended to operate an electric motor at a variable speed for the sake of improved efficiency. The main job of the inverter is to control the speed and torque of the motor to match work requirements.

Principle 

A fixed speed drive can run in two states: on or off. The energy consumption of such a system is higher because it runs at full power even when that is not needed. Fixed speed drives are designed to manage starting at full speed, which does not maximize efficiency. An inverter represents one of the basic components of a variable speed drive (VSD) that includes other components such as a rectifier, an intermediate circuit and a control unit.

The basic work of an inverter within a VSD is simple. A microcontroller integrated with the inverter manages the speed of a motor according to demands. For example, in a refrigerator data such as temperature, humidity and motor speed are gathered through sensors to keep the motor running efficiently. Based on such data, a microcontroller optimizes performance. Motor speed is optimized and keeps the refrigerator’s temperature constant.

Applications

Inverterization has multiple applications in home appliances and industrial drives. Most major home appliances, including refrigerators, washing machines, fans, vacuum cleaners and pumps, are inverterized.

Advantages

Inverterization offers  advantages in multiple domains:

 Higher durability through smoothly starting engines improves efficiency through an increase in power factor, and improves process control. 
 Reducing motor speed saves energy. For example, slowing down a fan motor from 100% to 80% when less airflow is needed can save as much as 50% ofn energy use.  
 Inverterization reduces noise and vibration.

Inverterization has become popular due to the low cost volume production of Intelligent Power Modules (IPMs) and the availability of easy-to-use designs. It is popular to use in electrical appliances such as fans and air conditioning systems, due to energy savings. In Japan, for instance, inverterization of washing machines reached 100% in 2011.

CASA-1000. The Central Asia-South Asia power project, commonly known by the acronym CASA-1000, is a $1.16 billion project currently under construction that will allow for the export of surplus hydroelectricity from Kyrgyzstan and Tajikistan to Afghanistan and Pakistan. Groundbreaking for the project took place in May 2016 by leaders of the four nations. The entire project is expected to be completed by 2025.

Project details

The project will allow for the export of 1,300 megawatts of electricity during the summer months when both Tajikistan and Kyrgyzstan experience surplus electricity generation from hydroelectric dams.

High voltage direct current (HVDC) converter stations will also be included as part of the project, as well as a 477 kilometer long, 500 kilovolt alternating current transmission line between Datka, Kyrgyzstan and Khujand, Tajikistan. A 1,300 MW AC/DC converter station will be constructed in the city of Sangtuda, Tajikistan. A 750 km HVDC line will be constructed between Sangtuda, Tajikistan and the city of Nowshera, Pakistan, via Afghanistan. A 1,300 MW DC/AC converter station will also be constructed in Nowshera, Pakistan and it will be connected to Pakistan's electric grid. The transmission line is designed to transmit up to 1,300 MW of electricity to Pakistan.

Additionally, an existing 220 kV AC line between Tajikistan and Afghanistan will be modified for a back-to-back HVDC connection. The modification will allow Afghanistan to draw up to 300 MW more power from the existing 220kV transmission line.

The project was inaugurated in February 2020, in a ceremony attended by Afghan President Ashraf Ghani and then-Pakistani Ambassador to Afghanistan Zahid Nasrullah Khan. As of March 2021, approximately 30% of the project covering Afghanistan was completed. In June 2021, Panjshir governor Kamaluddin Nezami consulted with citizens' and local government representatives on "social obstacles" to the CASA-1000 project.

Companhia Brasileira de Metalurgia e Mineração. Companhia Brasileira de Metalurgia e Mineração (Portuguese for Brazilian Metallurgy and Mining Company), or CBMM for short, is a Brazilian company that specializes in the processing and technology of niobium, extracted from its pyrochlore mine near the city of Araxá, in the Brazilian state of Minas Gerais.

CBMM is by far the world's largest producer of niobium metal and its alloys, providing over 80% of the world's supply. Like the other producers of this metal, the company does not sell raw niobium ore, only ferroniobium, other niobium alloys and oxides, and the pure metal, all produced in its facilities next to the open-pit mine. As of 2016, CBMM produces 90,000 tonnes of ferroniobium equivalent per year, which is slated to be increased to 150,000 tonnes/year. The Araxá ore deposit is large enough to supply the market demand for at least 200 years at current consumption rates. CBMM was the world's first mining and metallurgy company to be ISO 14001-certified.

CBMM's niobium products are sold to over 50 countries. The company has its business headquarters, manufacturing facilities and technology center next to its mine in Araxá, and an office for sales and application technologies in São Paulo, as well as sales subsidiaries in the Pittsburgh area, Amsterdam, Beijing, Shanghai and Singapore, and warehouses in Russia, India, Sweden, South Korea, Spain, Italy, Canada and Japan. CBMM also has a technology subsidiary in Geneva, CBMM Technology Suisse.

The company was founded in 1955 and since 1965 has been controlled by the Moreira Salles family, one of Brazil's wealthiest, former owners of the Unibanco banking conglomerate. In 2011, a Chinese group acquired a 15% stake in CBMM, and a Japanese-South Korean consortium a further 15%.

Harold Seddon. Sir Harold Seddon (6 March 1881 – 25 February 1958) was an Australian politician who served as a member of the Legislative Council of Western Australia from 1922 to 1954. He was President of the Legislative Council from 1946 to 1954.

Early life
Seddon was born in Openshaw, Lancashire, England, to Elizabeth Ann (née Davy) and William Seddon. His nephew, Harold Wilson, served twice as Prime Minister of the United Kingdom. After studying electrical engineering at the Manchester Technical Institute, Seddon worked for a period in the electrical department of the Great Central Railway. He emigrated to Australia in 1901, finding employment on the Eastern Goldfields as an electrical engineer with Western Australian Government Railways. Seddon became prominent in the Amalgamated Engineering Union, and also served on the Southern Cross Municipal Council.

Politics and later life
After the Labor Party split of 1916, Seddon joined the newly formed National Labor Party. He stood as the party's candidate in the seat of Kalgoorlie at the 1917 state election, but was defeated by the sitting member, Labor's Albert Green. From 1920 to 1922, Seddon served on the Kalgoorlie Municipal Council. He was elected to parliament in May 1922, winning election to the Legislative Council's North-East Province as a Nationalist candidate.

In November 1946, following the death of the President of the Legislative Council, James Cornell, Seddon was elected in his place. He was knighted for his service in June 1951. He served as president until the 1954 election, when he was defeated by Labor's John Teahan (in one of a series of Labor victories). Seddon lived in Kalgoorlie in retirement, dying there in February 1958, aged 76. He had married Winifred Jean Dunstan in 1932, with whom he had two sons and two daughters.
