T-122 Sakarya. The T-122 Sakarya is a Turkish multiple launch rocket system developed by ROKETSAN.

Overview 

As part of the modernization drive undertaken by the Turkish Military in the 1980s and 90s several new rocket systems were developed for the needs of the Turkish army. Prototypes of the system were revealed in 1995 with the first vehicles undertaking trials and evaluation in 1996. Production commenced in 1997.

The system consists of two pods of 122-mm launch tubes which are hydraulically traversed and elevated. It is equipped with a state-of-the-art fire control system which calculates firing data automatically for rockets with different warheads and is capable of storing up to 20 target coordinates. The vehicle can fire rockets singly or in salvo, with a full forty rocket launch taking less than 80 seconds and blanketing a target area of 500 m × 500 m. In addition the later versions of the T-122 features an integral hydraulic crane which allows reloading of rockets pods within five minutes.

The rockets for the system were developed and manufactured by MKEK and ROKETSAN, though the T-122 can fire 122mm rockets from the BM-21 and associated systems. Indigenous rockets are available with HE-FRAG or cluster warheads which can contain either anti-personnel or anti-tank submunitions. Maximum range of fire with extended-range rockets is up to 40 km.

Variants
TR-122: It has a warhead effective radius of ≥ 20 m, warhead weight	of 18.4 kg.
TRB-122: It has a warhead effective radius of ≥ 40 m, warhead weight	of 18 kg.
TRG-122: Guided rocket. It has a accuracy of ≤ 10 m, warhead effective radius of ≥ 40 m, warhead weight	of 13.5 kg with a minimum range of 13 km and maximum range of 30 km.
TRLG-122: Laser guided missile. The missile is same as TRG-122 along with the added laser seeker for laser guidance. Accuracy of the missile increased to ≤ 2 m.
İHA-122 : Air-launched supersonic ballistic missile. İHA-122 missiles are equipped with TV and laser-guided heads.

First production models of the T-122 Sakarya launcher vehicle were based on the German MAN 26.281 heavy utility truck. An improved variant of the system was revealed in 2005 which is based on the MAN 26.372 truck which is also used as the launcher vehicle for the J-600T Yıldırım short-range ballistic missile. The improved system is fitted to use factory-sealed disposable rocket pods that are specifically designed to be maintenance free, resistant to handling and environmental conditions and allow rapid reloading. The updated system can also be fitted with armour and an NBC system.

Weidemann GmbH. Weidemann GmbH is a multinational agricultural machinery company based in Diemelsee-Flechtdorf in the district of Waldeck-Frankenberg in Hesse, Germany. It produces Hoftracs, wheel loaders, telescopic wheel loaders and telehandlers, which are preferably used on farmland for feeding, scattering, fertilising, loading and stacking. The company has sites in Diemelsee-Flechtdorf and Korbach, and is part of the Wacker Neuson group.

History 

Maschinenfabrik Weidemann KG was founded in 1960, in Diemelsee-Flechtdorf (Hesse, Germany). From 1960 to 1972, the company focused on production of farmyard equipment and dung removal equipment. In 1972, Weidemann invented the Hoftrac farm crane. This small, articulated machine was specifically designed for narrow and low farmyard buildings.

In 1979, the company was renamed as Weidemann GmbH & Co. KG. Weidemann continued to expand over the next few years. In the early 1990s, the first foreign affiliate was established in the Netherlands and operations commenced at plant III in Gotha (Thuringia, Germany).

In 2005, the company then known as Wacker Construction Equipment AG (now Wacker Neuson SE) acquired Weidemann. This involved a further expansion of production capacity. The production plant in Korbach was completed in 2007. Since then, Weidemann GmbH has been a wholly owned affiliate of Wacker Neuson SE.

Weidemann machines are sold in over 30 countries worldwide by in-house organisations in close cooperation with specialist dealers. Since 1960, Weidemann has produced more than 65,000 machines (up to 2011).

In April 2021, the traditional location in Diemelsee-Flechtdorf was abandoned with the move into a new administration building, training center and technology center. The company location is therefore entirely in Korbach.

Small Satellite Conference. Internationally recognized as the premier conference on small satellites, the Small Satellite Conference (also known as SmallSat) is held each August on the campus of Utah State University (USU) in Logan, Utah, USA.

This annual gathering provides a forum for the best minds in the small satellite community to review recent successes, explore new directions, and introduce emerging technologies in small spacecraft development. In addition to creating an excellent environment for networking and speaking with experts in military, science, and academic fields, the Conference offers a program of international relevance, focusing on the key challenges and opportunities facing the small satellite community today.

History
The first Small Satellite Conference was held in 1987 on the campus of Utah State University in Logan, Utah, USA and has remained there for each succeeding conference. In the beginning, small satellites were not widely accepted but have since become a vital part of the space industry. ‘Small’ is a relative term as mass continually decreases to create new types of small satellites. Though no standard for small satellites is accepted by all, it is generally assumed to include satellites up to 250 kg.

In 1987 there were 50 to 100 attendees. In 2019 there were 3400 participants from over 40 countries that attended the week-long conference.

Frank J. Redd Student Competition
Named after Frank J. Redd, PhD, the founder of the Small Satellite Conference, the Student Competition provides undergraduate and graduate students pursuing a degree in an engineering or scientific discipline with the opportunity to share their work on small satellite concepts and missions.

Each year, college students from across the globe compete for awards made possible through generous donations from organizations and individuals within the small satellite community. Awards are given to competition finalists presenting at the Small Satellite Conference. The number and dollar values of the awards are determined on a yearly basis.

Vertical electrical sounding. Vertical electrical sounding (VES) is a geophysical method for investigation of a geological medium. The method is based on the estimation of the electrical conductivity or resistivity of the medium. The estimation is performed based on the measurement of voltage of electrical field induced by the distant grounded electrodes (current electrodes).

Measurements

Figures 1–4 show the possible configuration of the measurement setup. The electrodes A and B are current electrodes which are connected to a current source; N and M are potential electrodes which are used for the voltage measurements. As source, the direct current or low frequency alternating current is used.

The interpretation of the measurements can be performed based on the apparent resistivity values. The depth of investigation depends on the distance between the current electrodes. In order to obtain the apparent resistivity as the function of depth, the measurements for each position are performed with several different distances between current electrodes. The apparent resistivity is calculated as

 

here, k is a geometric factor,  — voltage between electrodes М and N,  — current in the line AB. The geometric factor is defined by

 

here r is the distance between electrodes.

Interpretation of gathered data is performed based on the dependency ρk(AB/2).

The application of large electrode arrays allows for reconstructing complex 3D structure of geological media (see Electrical resistivity tomography). However, the interpretation of such measurement is rather difficult.     
In this case, advanced interpretation techniques based on numerical methods can be applied.

Renzo Picasso. Renzo Picasso (1880–1975) was an Italian architect, engineer, and urban planner and designer.

He was the author of the early twentieth century utopian projects for the city of Genoa, such as that for the Piazza de Ferrari, which suggested a development in height for those urban and metropolitan cities with a population of three million inhabitants or more.

His numerous projects for skyscrapers (or rather the "cloudscratchers" as he used to call the high rising towers he dreamt to build, "grattanuvole") are set in a context of wide open spaces to ease human socialization.

He was also the inventor of machines and devices characterized by the use of advanced technologies, such as the Motovol and the auto-scafopattino.

The Yonah (locomotive). Yonah was a type 4-4-0 steam locomotive that participated in the Great Locomotive Chase of the American Civil War.

Before the Civil War 
Built in 1848 by Rogers, Ketchum & Grosvenor in Paterson, New Jersey, the Yonah was the third 4-4-0 locomotive purchased by the Western and Atlantic Railroad.  Very little is known about the engine's service life, but it is assumed to have served as a construction train as the railroad was being built from Atlanta, Georgia to Chattanooga, Tennessee, and was believed to have been the first engine to arrive in the latter city.

The engine was likely used for both freight and passenger service for the Western and Atlantic.  The Yonah was an example of an early 4-4-0 design, featuring a Haycock firebox design and having its pilot wheels closely spaced with the cylinder placed above at an angle.  Thus, the engine was likely relegated to yard service as early as the late 1850s, as the railroad had acquired larger, more powerful locomotives such as the General and the Texas.

Civil War 

During the Civil War, the Western and Atlantic had leased the Yonah to the Cooper Iron Works, which operated a short spur to their foundry from a junction at Etowah, Georgia.  On April 12, 1862, The General was commandeered by Northerners led by James J. Andrews at Big Shanty (now Kennesaw, Georgia), and passed the Yonah at Etowah as it traveled north towards Chattanooga.  Noticing that the Yonah was under full steam and ready for service, the group of raiders aboard the General suggested destroying the engine.  However, Andrews declined as he felt doing so would have little impact on the railroad and might draw attention to the raiders and their intentions.  Thus, Andrews and his train passed through Etowah without stopping and continued north.

The Yonah was about to make its morning run to the Cooper Works when William Allen Fuller, the conductor whose train had been stolen at Big Shanty, arrived at Etowah.  Fuller assumed control of the Yonah, and drove the engine in full steam northward for fifteen miles, arriving in Kingston.  Here, Fuller left the Yonah and continued north aboard the Rome Railroad's locomotive, the William R. Smith.

Later career

After the war, the Yonah is believed to have returned to Atlanta, where it was converted into a stationary boiler for the railroad's shop facilities.  The W&A's engine roster of January, 1873 listed the engine as "condemned" and "not to appear again on engine roster", and is presumed to have been converted to a stationary engine used to power shop machinery later that year, likely serving in this position until it was eventually scrapped.
