Flightline Flight 101. Flightline Flight 101 was an international flight from Barcelona El-Prat Airport in Barcelona, Spain to Ahmed Ben Bella Airport in Oran, Algeria. It crashed into the sea, probably due to a lightning strike leading to a loss of electricity.

Aircraft and crew 
EC-GDV was a Swearingen SA226-AT Merlin IVA Metroliner built in 1976. Prior to the accident it had accumulated 11,950 flight hours. It was powered by two TPE331-10UA engines. It was not equipped with a cockpit voice recorder nor a flight data recorder, and was not required to.

The captain and first officer, aged 33 and 43, respectively, were both Spanish nationals. Their total amount of flight experience is unknown.

Flight 
The aircraft took off from Barcelona-El Prat Airport at 10:18. It flew normally in the direction of Valencia before the last radio contact at 10:38 and disappeared from radar screens 4 minutes later, probably as a result of total electrical failure caused by a lightning strike. The loss of electricity rendered many systems inoperable, such as elevator trim, lighting and instruments, anti-ice and navigation. The aircraft then impacted the water at a steep pitch angle, as a result of either loss of control or spatial disorientation.

Cause

Investigators noted two instances where an electrical failure occurred on board an SA-226 due to a lightning strike. On February 8, 1988, Nürnberger Flugdienst Flight 108 broke up in mid-air after the pilots became disoriented due to a loss of electrical power caused by a lightning strike. Later in November 1991, another aircraft suffered a lightning strike and a total electrical failure. However the crew managed to restore power and land safely.

Considering this and the loss of radar contact, investigators concluded that the cause of the accident could not be determined, but stated that a likely scenario was

Trampling. Trampling is the act of walking on something repeatedly by humans or animals.

Trampling on open ground can destroy the above ground parts of many plants and can compact the soil, thereby creating a distinct microenvironment that specific species may be adapted for.

It can be used as part of a wildlife management strategy along grazing.

When carrying out investigations like a belt transect, trampling should be avoided. At other times, it is part of the experimental design.

Trampling can be a  disturbance to ecology and to archaeological sites.

Hell's Angels (aircraft). Hell's Angels was a Boeing B-17F Flying Fortress used during the Second World War. It was one of the first B-17s in the 8th Air Force to complete 25 credited combat missions in the European Theater. Ultimately, Hell's Angels would go on to complete 48 missions without any crewman injured or being forced to turn back.

Hell's Angels was often considered the first 8th Air Force B-17 to complete 25 credited combat missions. However, recent research by Mick Hanou, president of the 91st Bombardment Group Memorial Association and historian Jeff Duford, a curator at the National Museum of the United States Air Force, has confirmed that a B-17F of the 323rd Bombardment Squadron, 91st Bombardment Group, serial number 42-5077 and nicknamed Delta Rebel No. 2, completed 25 credited combat missions on 1 May 1943, becoming the first B-17 in the European Theater to complete the feat, two weeks before Hell's Angels. Delta Rebel No. 2, was shot down during the 12 August 1943 mission to Gelsenkirchen, Germany, with six of its crew captured as prisoners of war and four killed in action.

Windows Update MiniTool. Windows Update MiniTool (also called WUMT) is a freeware application client created by a Russian programmer named stupid user, and was released in 2015. It is an alternative to Windows Update for the Microsoft Windows operating systems by allowing users to search, install, postpone, and disable updates.

This program is available in four available languages: English, Spanish, Korean and Russian. It supports Windows NT-based operating systems in both 32-bit or 64-bit versions.

Interface & Features
The interface is divided into a sidebar that runs the program's function. The options are:

Query the update server.
Download selected updates but don't install.
Download and install selected updates.
Uninstall selected updates.
Hide (block) selected updates.
Copy the information to the clipboard.

Reception
The software received favorable reviews. Softpedia gave it a 4.5/5 with editor, Giorgiana Arghire wrote, "If you want to make sure that you do not forget about the postponed updates, you can use Windows Update MiniTool, as it allows you to download and install them when you choose."

Legacy
WUMT gained some notoriety in the early 2020s when Microsoft announced that they would be discontinuing the Windows Update service's SHA-1 endpoints for older versions of Windows in 2020 (which included Windows 2000, Windows XP, Windows Server 2003, and Windows Vista) citing weaknesses with the SHA-1 hashing algorithm as well as complying with newer industry standards. Because these operating systems will no longer receive updates via the Windows Update server due to this change, users have used the WUMT tool alongside other methods in order to get automatic updates working again for these operating systems via the Windows Server Update Services server.

Tokamak Chauffage Alfvén Brésilien. The Tokamak Chauffage Alfvén Brésilien (TCABR) is a tokamak situated at the University of São Paulo (USP), Brazil. TCABR is the largest tokamak in the southern hemisphere and one of the magnetic-confinement devices committed to advancing scientific knowledge in fusion power.

History 
TCABR was originally designed and constructed in Switzerland, at the École Polytechnique Fédérale de Lausanne (EPFL), and operated there from 1980 until 1992, under the name of Tokamak Chauffage Alfvén (TCA). The main focus of TCA was to assess and enhance plasma heating with Alfvén waves. In 1994, the machine was transferred to USP, passing through an upgrade and adding Brésilien to its name. The operation of TCABR began in 1999.

Properties 

The TCABR plasma is made of hydrogen and has a circular format. In general, its discharges are ohmically heated and the plasma current in TCABR reaches up to . The minor and major radii of TCABR are respectively  and , giving an aspect ratio of . The TCABR central electron temperature is around  (i.e., ) and its mean electron density is , in units of . Other parameters of TCABR include the toroidal magnetic field,  the hydrogen filling pressure, , a discharge duration of , and a steady-phase duration around .

Research program 
The current purpose of the TCABR tokamak includes the study of Alfvén waves, but is not restricted to it. Other research areas are (i) the characterization of magnetohydrodynamic (MHD) instabilities, (ii) the study of high-confinement regimes induced by electrical polarization of external electrodes in the plasma edge, (iii) the investigation of edge turbulence, and (iv) the study of plasma poloidal and toroidal rotation using optical diagnostics. The TCABR team is also associated with a theoretical group focused on investigating instabilities and transport barriers in tokamaks and dynamical systems.

An upgrade in the TCABR is also being conducted. A set of 108 RMP coils will be installed to control and study edge localized modes (ELMs). New shaping coils will be added, allowing great flexibility in plasma configurations (e.g. single null, double null, snowflake, and negative triangularity configurations). The vacuum-vessel inner wall of TCABR will receive graphite tiles to decrease impurity deposition and energy loss in the plasma.

Power-voltage curve. Power-voltage curve (also P-V curve) describes the relationship between the active power delivered to the electrical load and the voltage at the load terminals in an electric power system under a constant power factor. When plotted with power as a horizontal axis, the curve resembles a human nose, thus it is sometimes called a nose curve. The overall shape of the curve (similar to a parabola placed on its side) is defined by the basic electrical equations and does not change much when the characteristics of the system vary: leading power factor lead stretches the "nose" further to the right and upwards, while the lagging one shrinks the curve. The curve is important for voltage stability analysis, as the coordinate of the tip of the nose defines the maximum power that can be delivered by the system. 

As the load increases from zero, the power-voltage point travels from the top left part of the curve to the tip of the "nose" (power increases, but the voltage drops). The tip corresponds to the maximum power that can be delivered to the load (as long as sufficient reactive power reserves are available). Past this "collapse" point additional loads cause drop in both voltage and power, as the power-voltage point travels to the bottom left corner of the plot. Intuitively this result can be explained when a load that consists entirely of resistors is considered: as the load increases (its resistance thus lowers), more and more of the generator power dissipates inside the generator itself (that has it own fixed resistance connected sequentially with the load). Operation on the bottom part of the curve (where the same power is delivered with lower voltage – and thus higher current and losses) is not practical, as it corresponds to the "uncontrollability" region.

If sufficient reactive power is not available, the limit of the load power will be reached prior to the power-voltage point getting to the tip of the "nose". The operator shall maintain a sufficient margin between the operating point on the P-V curve and this maximum loading condition, otherwise, a voltage collapse can occur.

A similar curve for the reactive power is called Q-V curve.

GNR Class J14. The Great Northern Railway J14, later classified as J53 under LNER service, was a class of 52 0-6-0ST locomotives designed by Patrick Stirling and built at Doncaster Works by Neilson and Co and between 1892 and 1897.

The J14s were similar to the GNR Class J13 albeit with different boilers and without a steam dome.

Sub Classes
17 J14s were built with condensing equipment for the Metropolitan Railway while a further 10 had them retrofitted in 1900. All of these locomotives had extra lamp irons for Southern Railway running. These were later removed or added when the locomotives moved. Five J14s were rebuilt with G2 0-4-4 boilers (four of these were rebuilt as J13s between 1928 and 1932), while No. 3928 was withdrawn in 1935.
