Meghri Dam. The Meghri hydroelectric project (also known as the Meghri Dam or Aras Watershed Dam) is a hydroelectric project planned on the Aras River near Armenia's southern town of Meghri on the Armenia–Iran border.

The joint Iranian–Armenia project was proposed in the 1990s and was discussed between Iranian and Armenian authorities.  Intergovernmental agreements between Armenia and Iran were signed in 2007 and 2008.  On 14 April 2009, energy ministries of Armenia and Iran signed a memorandum on financing construction of the Meghri power station of Armenian side.  The dam and power stations construction contract was signed on 16 October 2010 with Farab Sepasad Company. A ceremony on 17 November 2012, attended by Iran's Minister of Energy and the Armenian President, officially began construction.

The basic studies were carried out by Arm-Hydroenergo-Project Company and Mahab-E-Qods Consulting Engineers Company in 1999.  The Meghri station was to be operated by Iran for 15 years after which it will be returned to Armenia free of charge.
However, construction has been delayed.  As of 2017, the Armenian government’s Deputy Minister of Energy Infrastructures and Natural Resources Hayk Harutyunyanays said 
"Although the agreement has long been in force, the Iranian company has not made any investments to this day, so the governments of Armenia and Iran have to look for another investor."
The project is expected to cost US$400 million.

Power stations
The complex was planned to comprise two  hydroelectric power stations — Ghare Chiler (also transcribed Gharachilar or Karachinar) on the Iranian side and Meghri on Armenia side.  Due to the sufficient difference in elevation and the presence of Aras Dam on the upstream, the power stations will be run-of-river type, wherein water is taken into pipes at a high elevation, carried downslope to powerhouses at lower elevation, then discharged back to the river.  Both power station were conceived to have two turbines with a capacity of  each.  Revised study of river flows now indicates total Meghri generation capacity would be approximately 100 MW.

DRG Class 25. Class 25 may refer to:

 Express train, steam locomotives with a 2-8-0 wheel arrangement operated by the Deutsche Reichsbahn in the GDR after World War II:
 The new, post-war locomotive (Neubaulokomotive): DR Class 25.0
 The trials locomotives: DR Class 25.10
 The electric multiple units of DRG Class ET 25, later DB Class 425, built for the Deutsche Reichsbahn in the 1930s.
Class 34. The DRG Class 34 refers to:

 Passenger train, tender locomotives with a 2-4-0 wheel arrangement operated by the Deutsche Reichsbahn:
 Class 34.70: BBÖ 231 (locomotive with 0-6-0 wheel arrangement)
 Class 34.73: Mecklenburg P 3.1
 Class 34.76: Saxon III
 Class 34.77–78: Saxon IIIb
 Class 34.79: Saxon IIIb V
 Class 34.80: Saxon VIb V
 Class 34.81: Württemberg A
 Class 34.82: Württemberg Ac
Saxon VIb V. The Saxon Class VIb  were four-coupled, tender locomotives in express train service with the Royal Saxon State Railways. In 1925, the Deutsche Reichsbahn grouped these engines into DRG Class 34.8.

History 
The Saxon Class VIb V locomotives were built from 1889 onwards in a total of 14 units by the Hartmann and were designed for hauling express trains. They were mostly retired by 1922. The Reichsbahn took over just one engine and gave it the running number 34 8011. It was retired in 1925.

Technical features 
These locomotives were the first compound locomotives in Saxony. Its two-cylinder, compound engine was located behind the carrying axle and drove the final axle. The locomotives had an inside Allan valve gear. The steam dome was in the centre of the boiler over the middle axle. The running gear had an improved Nowotny carrying axle, nevertheless it did not have good riding qualities. The Schleifer brakes were later converted to Westinghouse brakes.

Matrix molding. Matrix molding or matrix transfer molding is a technique often used during molding. The person doing the assembly will first create the rigid outer shell or flask, then introduce the softer and more fluid molding material between the shell and the prototype. This process is often used for complex shapes using composites such as with glass and glass/ceramic composites.

Württemberg A. Then locomotives of Württemberg Class A were express train steam locomotives operated by the Royal Württemberg State Railways. They were built from 1878 by the Maschinenfabrik Esslingen engineering works.

In the mid-1860s the Württemberg State Railways turned away from the 4-4-0 American-influenced locomotives and went back to 2-4-0 locomotives, because they were cheaper to buy and maintain. They even converted some 4-4-0s to 2-4-0 engines. 

Because these locomotives had been built over many years, the individual engines differed from one another in certain details and, for example, the boiler pressure was increased from . The engines had a tender of Class 2 T 10 and were recognisable by their large steam dome, that was located just behind the only slightly higher chimney.

Two locomotives ended up in the final DRG renumbering plan of 1925 as the DRG Class 34.81. Number 34 8101 was the former 336, that in 1896 had been converted from a Württemberg Aa. Number 34 8102, formerly 363, was by contrast newly built in 1891. Both locomotives were retired in 1925.

Pierson Building Center giant hammer. Pierson Building Center, a locally owned and operated home improvement center in Eureka, California, is home to the World's Largest Hammer.

The hammer is a replica of a Vaughan claw hammer (No. D020) and stands 26 feet tall (30 feet overall including the concrete foundation). The octagon-shaped handle is made of real solid wood and is reinforced with a metal I-beam. The hammer's head was fabricated from 18-gauge brushed stainless steel and measures 10 feet, 3 inches in length. All dimensions of the replica are in exact proportion to the original Vaughan hammer.

The hammer was permanently mounted in front of the business on November 12, 1991. It serves as the store's symbol as well as its sign post. Store specials and information are posted on the 12 foot by 7 foot backlit sign that is built into the hammer.

The Big Hammer briefly became a character in the nationally syndicated comic strip  Zippy the Pinhead by Bill Griffith.  The character appeared in two strips in August, 2001.

Muskingum Electric Railroad. The Muskingum Electric Railroad was a private coal-carrying railroad owned by American Electric Power, and started operation in 1968.  MERR shuttled coal in two trains from the mine to a powerplant at Relief, Ohio (across from Beverly, OH), a distance of 20 miles (32 km). The trains were driverless and powered by automated General Electric E50C's. The road also owned two private cars, Dover Fort and Oak Lane. The line is now defunct as the captive coal mine has since run out of economically recoverable coal. The coal was extracted by the largest dragline ever to be built, "Big Muskie". The railroad closed in January 2002.

The line was the first automated railroad in the U.S.

Diehl was a pioneer of aerodynamics and aircraft design. Serving in the U.S. Navys Bureau of Aeronautics, he directed the Navy's work in aerodynamics and hydrodynamics from 1918 until 1951. He was responsible for the funding, programs, and facilities of the Aerodynamics Laboratory. The author of the authoritative Engineering Aerodynamics, he actively participated in and strongly influenced continuing advances in aerodynamics and hydrodynamics.

Diehl initiated action that led to establishment of the David W. Taylor Model Basin at Carderock, Maryland, the Aircraft Research Station at Chincoteague, Virginia, and the U.S. Navys test flight unit at Naval Air Station Anacostia in Washington, D.C., which later developed into the Naval Air Test Center at Naval Air Station Patuxent River, Maryland.

Retirement and death

Diehl retired from the Navy in 1951 as a captain. He died in Washington, D.C., on 21 November 1976, and is buried at Arlington National Cemetery in Arlington, Virginia.

Vietnam Electricity. Vietnam Electricity (EVN; ) is the national and the sole public power company in Vietnam. It was established by the government of Vietnam as a state-owned company in 1994, and has operated officially as a one-member limited liability company since 2010.

History 
In 1994, the Vietnam electricity sector consolidated the electricity generation, transmission and distribution units to establish the Vietnam Electricity Corporation. Also in this year, the 500kV North-South transmission line was put into operation, connecting the power systems of the three regions of North, Central and South into a unified power system for the whole country.

Before 2006, the Vietnam electricity sector operated under a parent-subsidiary model, with the Vietnam Electricity Corporation as the parent company. Then, on June 22, 2006, this corporation was converted into the Vietnam Electricity Group (EVN). On June 25, 2010, the Prime Minister of Vietnam decided to convert the Vietnam Electricity Group model into a single-member limited liability company controlled by the state.

Criticism 
EVN is facing various criticisms, notably the lack of clear separation between social responsibility and business responsibility from the Government and EVN itself. For example, providing electricity to remote and island areas by 2023 still faces difficulties due to the lack of clear support policies, leading to challenges in evaluating operational efficiency. EVN's apparatus remains cumbersome and requires restructuring to enhance effectiveness. Although customer service has seen improvements, certain limitations persist. According to a 2022 survey by the Ministry of Industry and Trade, the customer satisfaction rate with EVN's services reached 80%, with 20% remaining unsatisfied. The purchase and dispatch of electricity from power plants outside of EVN lack transparency, causing public controversy. A 2021 report by the State Audit Office of Vietnam pointed out shortcomings in EVN's bidding process for electricity procurement.

Cardboard modeling. Cardboard modeling or cardboard engineering is a form of modelling with paper, card stock, paperboard, and corrugated fiberboard. The term cardboard engineering is sometimes used to differentiate from the craft of making decorative cards. It is often referred to as paper modelling although in practice card is generally used.

History 
Originally this was a form of modelling undertaken because of the low cost involved. Card, a means of cutting and glue are all that is needed. Some models are 100% card, while others use items of other materials to reinforce the model. After World War II cardboard models were promoted by a number of model companies. One company, ERG (Bournemouth) Ltd. produced a book "Cardboard Rolling Stock and How to Build It" and Superquick are still well known for their range of printed and pre-cut kits.

Books of printed models to cut out and make have been around a long time. Also, specially printed cards were available from which models could be made. In the UK Micromodels were well known for very small card models.

Models to cut out were also a feature of paperboard folding cartons. For many years, breakfast cereal makers had models to cut out on their packets.

The hobby has been revived through the use of ink-jet and laser colour printers, with the availability of inexpensive cutting plotters and laser engravers also reducing the time, effort, and tedium associated with cutting out the many parts. Using a vector graphics package, it is even possible for anyone to create their own models from scratch, though most use special software.

Models to cut out can also be downloaded from the internet.
