Skipjack Wind Farm. Skipjack is a 966 MW capacity off shore wind farm, proposed by Ørsted US Offshore Wind to be built on the Outer Continental Shelf Offshore Delaware, approximately  from the coast opposite Fenwick Island. It was originally projected that the project, which will provide power to Maryland, would be commissioned in 2022,  It is one of the wind farm  projects providing wind power to Maryland, the others being MarWin and Momentum Wind.

The initial phase would produce 120 MW. A second project phase was approved by Maryland regulators in December 2021 to have an additional 846 MW. Both will be developed together. In January 2024, the developer "repositioned" the project, temporarily curtailing its construction.

WEA
The project will be built in BOEM-designated Wind Energy Area (WEA) OCS-A 0519, an area of  approximately 16.9 nautical miles or  off the Delaware coast between Indian River Outlet opposite Fenwick Island, north of the Maryland WEA.

Infrastructure
Skipjack will use 10 GE Wind Energy Haliade-X 12 MW turbines,  feet tall with rotors  long (with blades each  long), made in Cherbourg, France. The nacelles are also produced in France.

Ørsted U.S. Offshore Wind will partner with Tradepoint Atlantic, based in Port of Baltimore, to develop a logistics center to create a 50-acre staging center for on-land assembly, storage and loading out into deep waters.

The Port of Paulsboro on the Delaware River in New Jersey could become the site for the production the monopile foundations for turbines.

Ørsted proposed using 1.5 acres of land in Fenwick Island State Park in Delaware as a transmission point, but locals opposed park upgrades to be paid for by the project.

ORECs
The Maryland Public Service Commission has authorized ORECs (offshore wind renewable energy certificates) for both Skipjack and MarWin. ORECs for the second phase were approved in 2021.

Visibility from shore
Residents and business, particularly in Ocean City, Maryland, have raised concerns about the potential of negative impact of building a wind farm offshore, thus creating a landscape that could affect tourism.
The turbines have changed in size since the initial proposal by the predecessor of Orsted. They will be  feet tall.

Unity Operating System. Unity Operating System (also known as Unified Operating System or UOS, ) is a Linux distribution developed by UnionTech (, Tǒngxìn) based on Deepin, which is based on Debian. It is used in China as part of a government initiative beginning in 2019 to replace foreign-made software such as Microsoft Windows with domestic products.

Development 
Three versions are currently under development, a desktop for regular users (Deepin), another for enterprises (UOS) and a server version (UOS). A first beta version was released in  and can be downloaded from the official website. A first stable version was released on 14 January 2020.

Support 
The operating system is primarily aimed at the Chinese market and is intended to replace Microsoft Windows in the country by 2022, also known as "3-5-2 policy". So far, the focus has therefore been primarily on in house hardware such as that from the semiconductor company Zhaoxin. The whole KX-6000 series is already supported by the desktop version as well as the KH-30000 series for server version.

It was reported on July 23, 2022 that the operating system could support HarmonyOS app file format, hap .app.

Broad support is planned, so platforms such as Loongson, Sunway or ARM are also to be supported.

Turkish Electricity Transmission Corporation. Turkish Electricity Transmission Corporation (Turkish: Türkiye Elektrik İletim A. Ş., abbreviated TEİAŞ) is the transmission system operator for electricity in Turkey. It is a government-owned corporation. It is planned for a minority stake to be sold to the private sector before the end of 2022. It reportedly does not co-ordinate with EMRA re YEKA bids as of 2023.

History
In 2006, investigations were begun by ENTSO-E, the European Network of Transmission System Operators, into the technical conditions for the interconnection of the national grid of Turkey to the continental European power system. A trial period of interconnection commenced on 18 September 2010, and after the signing of long term agreements, the interconnection with Europe became a permanent arrangement.

There was a nationwide blackout in 2015.

Operations
According to a study by Sabancı University 20% of Turkey's electricity could be generated from wind and solar by 2026 with no extra transmission costs, and 30% with a minor increase in grid investment.

Subsidies
TEİAŞ distributes extra payments to some power stations in Turkey: some hydro is supported, but this "capacity mechanism" has been criticised as wasting money on too much capacity by supporting some  coal fired power stations in Turkey.

High-speed launch. A high-speed launch (HSL) is a type of military boat typically used for air-sea rescue operations.  The British Royal Air Force (RAF) and others used HSLs especially during World War II.

The 64 ft. high-speed, air/sea rescue launch built by British Power Boat Company (BPBC) was one of the earliest high-speed offshore rescue vessel used by the Royal Air Force. The prototype, numbered 100, gave its name to the class as the "100 class"; High Speed Launch 102 is the only surviving boat from that class. It was tested in 1936 and production boats were delivered in 1937.

Later designs included the 1941 Type Two 63 ft HSL "Whaleback", an adaptation of a motor anti-submarine boat, the first HSL to include gun turrets. British Power Boat chief designer George Selman later designed the 68 ft. "Hants & Dorset" 

By May 1944, The RAF had 130 HSLs.

Minister of Electricity (New Zealand). The Minister of Electricity was a minister in the government of New Zealand with responsibility for the New Zealand Electricity Department.

History
The First Labour Government enacted the Electricity Act 1945 which split the hydro-electric branch of the Works Department would be constituted as a separate organisation. Additionally a Minister-in-Charge was to be made responsible for the administration of both the Act and the newly established State Hydro-electric Department. In 1958 the Second Labour Government passed the Electricity Amendment Act which established a dedicated Electricity portfolio as a full cabinet level role, whose minister was responsible for the administration of the Electricity Act and accountability for the New Zealand Electricity Department (superseding the State Hydro-electric Department). In 1978 the Electricity portfolio was abolished and its responsibilities were transferred to the Minister of Energy after the Third National Government passed the Ministry of Energy Act 1977.

Gereb Segen (Hintalo). Gereb Segen is a reservoir located in the Hintalo Wajirat woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2000 by SAERT.

Dam characteristics 
 Dam height: 14.86 metres
 Dam crest length: 473 metres
 Spillway width: 8 metres

Capacity 
 Original capacity: 337408 m³
 Dead storage: 22400 m³
 Reservoir area: 11.7 ha
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 25 years.

Irrigation 
 Designed irrigated area: 24 ha
 Actual irrigated area in 2002: zero ha

Environment 

The catchment of the reservoir is 3.53 km2 large, with a perimeter of 11.66 km and a length of 5200 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is Agula Shale. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.

Gereb Segen (May Gabat). Gereb Segen is a reservoir located in the Inderta woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2016 by the Tigray Water Bureau, with the main aim of providing Mekelle with water.

Challenges 
In 2018-2019 the reservoir was unable to sustain the water needs of Mekelle
 Pipe diameters are underfit
 Leakage through the abutment

 Sediment deposition by May Gabat river

Irrigation 
Though the reservoir was not intended for irrigation, its seepage water is used in the downstream valley for irrigation. The lithology of the catchment is Antalo Limestone. Part of the water is lost through seepage; the positive side-effect is that this contributes to groundwater recharge, and it allows irrigation by the downstream communities.

Nimble Titan. Nimble Titan is an Integrated Air and Missile Defense (IAMD) recurring two-year wargame campaign series that provides for national security and military policy experimentation in a notional scenario set 10 years in the future. It is the premier forum of U.S. Strategic Command for developing experimental IAMD national security and military policy among U.S. allies and partners. The experimental nature of the wargame is to stimulate participants to think outside of the constraints of current international and national norms, policies, and procedures.

Established in the 1990s, Nimble Titan was originally a U.S. Joint Staff wargame initiative to develop and test missile defense design concepts and capabilities at the tactical and operational level. In 2002, Nimble Titan became a bilateral wargame, in cooperation with the United Kingdom, that experimented with interceptor shot doctrine, automated battle management aids, decision support tools, early warning, integration and interoperability, and command and control authorities. In 2006, the Joint Staff relinquished control of Nimble Titan to U.S. Strategic Command. The wargame series expanded to include participant nations from both Western Europe and the Indo-Pacific. Multiple nations from around the world began to participate as interested observers. The focus of the wargame series evolved to investigate international and national strategic policy issues, rather than tactical and operational technical and procedural issues. Since 2006, Nimble Titan has grown in scope and scale. It now regularly hosts over 100 participants from 24 nations, NATO and other international organizations, as well as multiple nations in observer status.

Thexylborane. Thexylborane is a borane with the formula [Me2CHCMe2BH2]2 (Me = methyl).  The name derives from "t-hexylborane" (although the group is not the standard tert-hexyl group), and the formula is often abbreviated ThxBH2.  A colorless liquid, it is a monoalkylborane.  It is produced by the hydroboration of tetramethylethylene:
B2H6  +  2 Me2C=CMe2  →  [Me2CHCMe2BH2]2

Reactions
Thexylborane is generated in situ.  In solution, it isomerizes over the course several days to the 2,3-dimethyl-1-butyl derivative, shown as the monomer here:
Me2CHCMe2BH2  →  Me2CHCH(Me)CH2BH2

Thexylborane allows the synthesis of ketones by coupling a pair of alkenes with carbon monoxide, which serves as a carbonyl linchpin:
Me2CHCMe2BH2  +  2 RCH=CH2  →  Me2CHCH(Me)CH2B(CH2CH2R)2
Me2CHCH(Me)CH2B(CH2CH2R)2  +  CO  +  H2O  →   O=C(CH2CH2R)2  +  ...
An important feature of this reagent is that the thexyl group almost never undergoes anionotropic 1,2-migration from boron to a neighboring atom.

Grounding resistance tester. A grounding resistance tester also called an earth tester is a soil resistance measuring instrument. It is used for sizing and projecting grounding grids.

The first soil resistance measuring instrument was invented in the 1950s by Evershed & Vignoles Meggers who made the first insulation and earth resistance testers. One of the most used analog grounding testers in USSR were М416. From the 21st century several companies produced digital earth resistance meters and testers. The main purpose of the instrument is to determine the adequacy of the grounding of an electrical system. By a standard of the National Electrical Code the resistance of the soil should be less than 25 Ohms to reliably and efficiently ground the installation.

Operating principle 
The meter generates an electrical current and then supplies it to the measuring electrodes. The potential difference between the two electrodes gives information about the value of soil resistance.

Analog grounding resistance tester 
The analog grounding resistance tester is realized by four main blocks DC generator, rectifier, current and potential coil. The deflection of the pointer of the analog screen depends on the ratio of the voltage of pressure coil to the current of the current coil.

Digital grounding resistance tester 
The digital grounding resistance tester is realized by digital electronic blocks as Timers, voltage regulators, and digital display. The ranges are changed with multiturn trimpot.

Main characteristics  
When measuring earth resistance with an instrument, it is important to know some of its basic characteristics in order to accurately measure the soil resistance and to properly size the grounding installation. Most importantly, the range of resistance the device measures. Usually the range is three or four degrees. The soil moisture at which the appliance operates is another important parameter. If the instrument cannot operate at a certain humidity, then the measurement may differ significantly from the real value of soil resistance.

Laird B-4. The Laird B-4, aka Laird 1915 biplane, was the fourth aircraft built by Matty Laird in the United States of America. It was an excellent aerobatic aircraft and was used very effectively in performances by Laird, as well as by Katherine Stinson during her tour of Japan and China.

Design and development 
During the period when Matty Laird was performing as a barnstorming pilot, he designed this as an aerobatic aircraft for his own use. He built the aircraft with assistance from his brother Charles and friend George E. “Buck” Weaver. The aircraft was constructed from wood, fabric, and wire bracing. It was powered by a  six-cylinder Anzani radial engine. Laird was approximately 20 years old when he built the aircraft.

Laird referred to the aircraft as “My Anzani-powered machine” as well as “Boneshaker” because the powerful engine generated such strong vibrations in the airplane.

Operational history 
The aircraft's power and structural strength made it excellent for aerobatics, and Laird's flying skill enabled him to take advantage of the aircraft's characteristics and to perform several challenging maneuvers. For instance, he performed the loop-the-loop, which only a few American pilots could perform prior to World War I. Laird's performances in the aircraft generated significant public awareness of him and the aircraft.

Laird loaned the aircraft to Katherine Stinson for her 1916-1917 flying exhibition tour to Japan and China. This tour created tremendous attention for Stinson and for Laird's aircraft within and beyond the two countries.

Aircraft on display 
Laird donated the aircraft to the Henry Ford Museum and it is on display there.

JERA. JERA () is a 50-50 joint venture between TEPCO Fuel & Power, a wholly owned subsidiary of Tokyo Electric Power Company, and Chubu Electric Power, founded in April 2015. The company assumed ownership and operation of all of Tokyo Electric and Chubu Electric thermal power stations, giving it a total output of approximately 67 million kW (including capacity under construction), which made it Japan's largest power generation company. The electricity generated is wholesaled to retail electric utilities such as TEPCO Energy Partner and Chubu Electric Power, and is not supplied directly to consumers.

Background
The concept of JERA was floated immediately after the Fukushima Daiichi nuclear disaster by a group of young managers within Tokyo Electric, who sought to separate the thermal power generation portion of the company from the nuclear sector (together with the legal and fiscal responsibility for the accident) to ensure Tokyo Electric's survival. The idea was vehemently opposed by Tokyo Electric's chairman; however, by 2012 Tokyo Electric was facing imminent bankruptcy over damage compensation claim and the costs of decommissioning the Fukushima nuclear plants, as well as high costs for fossil fuel to make up the power generation shortfall from its 17 idled nuclear reactors. In addition, many of its thermal power plants were obsolete, and with Tokyo Electric's plummeting credit rating, it was deemed unlikely and the necessary funding could be secured for revamping or construction.

From March 2014, Tokyo Electric began to solicit partners for a strategic alliance. Meanwhile, Nagoya-based Chubu Electric was eager to expand into the Kanto region and had been receiving many enquiries from Kanto-based users unhappy with Tokyo Electric's increasing rates. However, efforts to enter the Kanto region and to compete against Tokyo Electric were hampered by the Japanese government's unwritten regulations creating regional electric generation monopolies. Chubu Electric initially attempted to circumvent these regulations by building a new 650,000 kW coal-fired power generation facility on the premises of TEPCO's Hitachi Naka Thermal Power Station, with power generated by this plant to be sold by Tokyo Electric on its behalf. This led to further discussions in September 2014 for a comprehensive alliance on thermal power generation, and JERA was launched in April 2015.

In November 2024, JERA announced its plan to restart coal and biomass co-firing at its Taketoyo thermal power station in central Japan around the beginning of April 2026. Jera will conduct coal-only operations during winter and summer starting around January 2025 to ensure a stable electric supply.

Burgess Field Nature Park. Burgess Field Nature Park (also known as Burgess Field) is a nature reserve next to Port Meadow, Oxford, in Oxfordshire, England, managed by Oxford City Council.

Overview
The site is between Port Meadow to the west and the railway line to the east, just north of the Aristotle Lane entrance to Port Meadow and the Trap Ground Allotments. The reserve is on a reclaimed landfill site and is approximately  in area. There are open grass areas, some woodland, and a path around the edge of the site, as well as some paths crossing the site. Wildlife includes birds such as cuckoo, short-eared owl and jack snipe.

The site was used for landfill until the 1980s and is thus higher than Port Meadow, which regularly floods. The area was landscaped, with trees and hedge planting in the 1990s. The name may derive from the burgesses who endowed Godstow Nunnery with land.

John Thompson

The site includes a memorial stone to John Thompson (1941–2015), the city of Oxford's landscape architect, who inspired the nature reserve and planted over 10,000 trees in Oxford.

Friends of Burgess Field
There is a Friends of Burgess Field organization, formed in 2018. Volunteers help to maintain the site.
