Kékéli Thermal Power Station. Kékéli Thermal Power Station, also Kékéli Efficient Power Station, is a  natural gas-fired thermal power plant located in the city of Lomé, the capital of Togo.

Location
The power station is located in the neighborhood known as Kékéli, located in the area of the Port of Lomé. "Kékéli" means "daybreak" in the local Mina language.

Overview
The power station is owned and operated by a special purpose vehicle company, which for descriptive purposes we will call Kékéli Energy Company (KEC). KEC is a public private partnership; a joint venture between Kékéli Efficient Power, a Togolese subsidiary of Eranove, the French water and electricity infrastructure development and management  conglomerate, based in Paris, and the  Government of Togo.

The power station is a combined cycle installation with two phases, built separately but intended to work in synchrony. The first cycle built between June 2019 and April 2021, uses an SGT-800 gas turbine to generate 47 megawatts of electricity. In this phase, natural gas is mixed with air and ignited, the hot air produced, turns the turbine to generate the electricity.

The second cycle expected to be added between May 2021 and December 2021, uses the hot exhaust gases from the first cycle to heat water and convert it to steam in a heat recovery steam generator. The steam then generates an extra 18 megawatts of power in an SST-200 steam turbine, bringing the total output to 65 megawatts.

Ownership
The special purpose vehicle company, referred to descriptively as Kékéli Energy Company, is owned by a consortium, as illustrated in the able below:

Funding
Development of this power station benefitted from funding provided by (a) West African Development Bank (b) Africa Finance Corporation (c) Orabank Togo (d) BIA Togo (e) NSIA Benin and (f) Banque Atlantique Togo. The investments in the power plant are guaranteed by GuarantCo, a subsidiary of the Private Infrastructure Development Group, based in London, United Kingdom.

Other considerations
When fully constituted, the power station will supply 532 GWh of power annually. This electricity will be sold directly to Togo Electricity Company (Compagnie énergie électrique du Togo), under a 25-year power purchase agreement. The energy generated is enough to supply 250,000 Togolese households or 1.5 million people, equivalent to an estimated 20 percent of the population of the country.

Parsons problem. Parsons problems are a form of an objective assessment in which respondents are asked to choose from a selection of code fragments, some subset of which comprise the problem solution. The Parsons problem format is used in the learning and teaching of computer programming.

Dale Parsons and Patricia Haden of Otago Polytechnic developed Parsons's Programming Puzzles to aid the mastery of basic syntactic and logical constructs of computer programming languages, in particular Turbo Pascal, although any programming language may be used. Parsons' programming puzzles became known as Parsons puzzles and then Parsons problems. Parsons problems have become popular as they are easier to grade than written code while capturing the students problem solving ability shown in a code creation process.

Structure 
Parsons problems consist of a partially completed solution and a selection of lines of code that some of which, when arranged appropriately, correctly complete the solution. There is great flexibility in how Parsons problems can be designed, including the types of code fragments from which to select, and how much structure of the solution is provided in the question. Easier Parsons problems provide the complete block structure of the solution included in the question, and the provided lines of code simply need to be reordered and inserted into that structure.

In the Parsons problem exam question, the first example shown, there are 6 pairs of statements, one mark is deducted for each incorrectly chosen line from the pairs, two marks are deducted if more than 2 lines are out of place, and one mark is deducted if up to two things are out of place. One mark is deducted if opening and closing braces are incorrectly used, or are not include where necessary.

Variants

Two-dimensional 

The two-dimensional variants require the student to also correctly indent the code instead of merely re-ordering the provided lines of code.

Faded 

In the faded variants, the lines of code may additionally contain blanks that the student needs to fill in.

Advantages 

The advantages of Parsons problems include:
 being a complement or alternative to traditional programming exercises like code-tracing and code-writing
 the design of Parsons problems is flexible
 there are many variants that are continuously refined to better address student needs

However, the effectiveness of Parsons problems, both as a question type and as a learning tool in CS education, remains uncertain due to a lack of replicated research in the field.

Automation 
Parsons problems can be automated.

Rampur chaddar. A Rampur chaddar (Rampur chadar) was a kind of handspun woolen shawl that originated in the town of Rampur in Himachal Pradesh, India, during the 19th century. They were later manufactured in cities of the Punjab such as Ludhiana and Amritsar, and also imported from outside India.

Name 
 is a Hindi word that means sheet (a rectangular piece of cloth). Rampur chaddar was named after the Rampur Bushahr.

Material 
There were at one time 2000 shawl weavers and 500 wool manufacturers in Rampur. They used to obtain the wool from Bushahr.

Texture 
The texture was fine yet warm. Rampur chaddars were made with wool or wool warp and silk or cotton in the weft. Though the quality was fine, soft, and durable, it was not equal to Pashmina.

Use 
Rampur chaddars were liked as wrap or shawl and were sold throughout India. They became popular in the late 19th century as a result of the import of power-loom woven examples sold as being of Indian manufacture.

Traverse (fortification). A traverse, in military fortification, is a mass of earth or other material employed to protect troops against enfilade. It is constructed at right angles to the parapet manned by the defenders, and is continued sufficiently far to the rear to give the protection required by the circumstances, which, moreover, determine its height. A traverse is sometimes utilized as a casemate. Ordinary field works, not less than those of more solid construction, require traversing, though if the trenches, instead of being continuous, are broken into short lengths, they are traversed by the unbroken earth intervening between each length.

Empresas ICA. Empresas ICA is a construction company that was founded on 4 July 1947, by Mexican civil engineer Bernardo Quintana Arrioja. The company has built multiple landmarks, buildings, and facilities in Mexico, including the Estadio Azteca, the modern Basilica of Our Lady of Guadalupe and Infiernillo Dam, and internationally, Aguacapa Dam, in Guatemala.

History
ICA was formed and founded after 17 engineers quit their previous jobs. They received their first contract, which was to create the . In 1953, ICA founded two subsidiary companies: Estructuras y Cimentaciones (ECSA) and Conducciones y Pavimentos (IASA), which were made to split the workload of the company. During the 1960s, ICA began to undertake larger infrastructure projects, including the Infiernillo Dam, the Mexico City Metro, and the Estadio Azteca. In 1992, they joined the Mexican Stock Exchange and the New York Stock Exchange.

Spangold. Spangold is a family of shape memory-effect alloys (SME) of gold, copper, and aluminum in either 18K or 23K. The name of the family is a play on the word "spangled".

Spangold is a beta-phase alloy with a nominal stoichiometry of Au7Cu5Al4 and a nominal composition by mass of 76% gold, 18% copper, and 6% aluminum. The texture is caused by the induction of a martensitic-type phase transformation on a polished surface.

Spangold undergoes a martensitic-type phase transformation when properly treated. This phase transformation is induced on a polished surface of the alloy. Martensitic transformations are a common feature in shape memory alloys, and they involve a reversible change in crystal structure that allows the material to recover its original shape when subjected to specific temperature changes.

Chinese frigate Xuchang. Xuchang (536) is a Type 054A frigate of the People's Liberation Army Navy. She was commissioned on 23 June 2017.

Development and design 

The Type 054A carries HQ-16 medium-range air defence missiles and anti-submarine missiles in a vertical launching system (VLS) system. The HQ-16 has a range of up to 50 km, with superior range and engagement angles to the Type 054's HQ-7. The Type 054A's VLS uses a hot launch method; a shared common exhaust system is sited between the two rows of rectangular launching tubes.

The four AK-630 close-in weapon systems (CIWS) of the Type 054 were replaced with two Type 730 CIWS on the Type 054A. The autonomous Type 730 provides improved reaction time against close-in threats.

Construction  
Xuchang was launched on 30 May 2016 at the Huangpu Shipyard in Shanghai. Commissioned on 23 June 2017.

Operational history 
In 2019, Xuchang took part in anti-piracy operations in the Gulf of Aden.

On June 3, 2019, the ship had a four-day stopover in Sydney Harbour, Australia on the return trip as part of a three-ship taskforce along with the Type 071 amphibious transport dock Kunlun Shan and the Type 903 replenishment ship Luomahu. According to then-Prime Minister Scott Morrison, the naval visit was invited by the Australian Government, but the neither the New South Wales government nor the Australian public were informed ahead of the taskforce's arrival, which triggered a media frenzy among the conservative Australian media and politicians on the backdrop of rising geopolitical tension in Sino-Australian relations. 
Xuchang is currently deployed in the red sea due to the Red Sea crisis.

Chollima-091. The Chollima-091 () is a high-floor, articulated trolleybus built from 2009 to 2018 by Pyongyang Trolleybus Factory for the Pyongyang trolleybus system. The name refers to the Chollima Movement which in itself derives from the mythological Chollima while the model number means year of development 2009, model 1. Since the 1960s, most of the trolleybuses in Pyongyang were named after this mythological creature. It was first produced as a prototype in 2009 and entered mass production in 2010. It is the most common vehicle in Pyongyang's trolleybus network and the vehicle with the most number in service in the DPRK.

Design 
Unusually, the rear door is used for loading, while passengers disembark in the other doors. There is a half door and a double door located in the front section, where the motor is housed, and one door at the rear section. These vehicles represent a design change from previous vehicles built up to the 1990s, with the passenger compartment being designed to allow as many passengers as possible. Hence, most of the seats are single seats with double seats over the wheel wells, which already occupy some space. The driver's cabin is not separate from the passenger cabin, unlike vehicles built prior to 1986.

These vehicles are not equipped with air conditioning, as it would likely consume too much electricity, which was in short supply. Instead, the vehicles have large sliding windows and fans within the cabin to ventilate the cabin. The vehicle has no insulation near the trolley poles or at the door steps. Each trolleybus is assembled manually, welding together frames; this means vehicles might have slight differences. The paint is also applied by hand with a total of 17 paint variations. Due to the handmade nature, the vehicle does not run smoothly. The articulation joint is based on the Ikarus 280, although since the design is rather primitive, it causes creaking noises in motion, with occasional jamming of the joint occurring.

The motor is a 130 kW switched reluctance motor, running at 1800 rpm. The maximum speed in service is 45 km/h. Driving axles are built by China National Heavy Duty Truck Group. The vehicle is reported to fitted with a kneeling suspension.

Compared to previous single section trolleybuses, the capacity is increased by 2.5 times and compared to older articulated buses, it is improved by 1.4 times.

Variants 
There are a number of variations in this vehicle. Mass production vehicles use rheostat control system, while one vehicle was fitted with an electronic control. This vehicle is also the only Chollima-091 fitted with a standard, two panel front door. Some vehicles also appear to have been fitted with alternating current motors instead.

A model with a flatter frontal section appears to have been developed in parallel with the first version and neither have appeared to supersede each other.

On November 2, 2011, Yuncheng and Haikou formed the tenth navy escort fleet from Zhanjiang City, Guangdong Province to perform escort missions in the Gulf of Aden and the waters of Somalia. The escort lasted 186 days, with a total voyage of 98,180 nautical miles, and completed 40 batches of 240 Chinese and foreign ships. On June 7, 2012, Yuncheng returned to Zhanjiang Military Port.

On October 22, 2012, Yuncheng, Haikou and Guangzhou crossed the waters south of Okinawa and went to the western Pacific waters for routine training.

On 19 December 2013, the South Sea Fleet consisting of Huangshan, Yuncheng, and Weishanhu set sail from Zhanjiang City and proceeded to the Western Pacific and other waters. Exercises in subjects such as continuous maritime alert, counter-terrorism and counter-piracy, and joint search and rescue.

In May 2014, the China National Offshore Oil Corporation's drilling platform Offshore Oil 981 conducted drilling operations in the Xisha waters. On May 13, Yuncheng arrived in the sea area where the drilling platform was located, driving away the Vietnamese coast guard ship that was interfering with the operation. On August 1, Yuncheng, Changbai Shan and Chaohu formed the eighteenth navy escort formation from a military port in Zhanjiang, and then went to the Gulf of Aden and Somalia.

Chaohu alongside Yuncheng and Changbai Shan made a goodwill visit to Rotterdam on 30 January 2015.

River Ring (development). River Ring is a mixed-use development planned for the Williamsburg neighborhood of Brooklyn in New York City. Two Trees, the project's developer, commissioned a design from BIG and James Corner Field Operations.

Development and history
Consolidated Edison previously occupied the three lots on which River Ring will rise, using them for purposes including oil storage. Two Trees, the project's developer, purchased the lots in 2019 for $150 million. Two Trees first released public renderings of the project's structures in late 2019. The project abuts the Domino Sugar Redevelopment, also a Two Trees development. Part of the Domino project, Domino Park, was designed by James Corner Field Operations; the firm will also design the outdoor portions of River Ring.

The project will have two towers, originally planned to top out at  respectively. Revised plans for the two towers were released in early 2021, increasing the height of one tower to 710 feet and decreasing the other to 560 feet. The project requires rezoning for construction to begin, as zoning currently mandates using the space for commercial or industrial purposes. The project must also go through New York City's Uniform Land Use Review Procedure. An organization, Sustainable Williamsburg, has objected to the rezoning plans. Two Trees anticipates completion by 2027.

Before construction begins, the site will host a miniature golf course and a farm. The golf course opened in July 2021. The development went before the City Planning Commission on August 16, 2021. Two Trees said it would sell the site to a logistics company if the development was not approved. In December 2021, the plan for the development was approved.

In June 2022, a property tax break known as 421a the development was going to utilize expired. Two Trees said that the new tax break, 485x, has requirements that are too strict to make the project financially feasible. The new requirements included much higher minimum wages for construction workers, new affordable housing requirements, and new income band caps. As of May 2024, the development has not started construction because of these reasons.

Design and usage
The buildings will have approximately 1200 residential units, as well as office space and a YMCA. In addition to the residential structures, the development will include a private park with a beach, designed to soak up floodwater, as the development will sit in a floodplain.
