Indian locomotive class WAG-6B/C. The Indian locomotive class WAG-6B/C is a class of 25 kV AC electric locomotives that was developed in the 1988 by Hitachi for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods (G) engine, 6th generation (6) Second/Third variant (B/C). They entered service in 1988. A total of 12 WAG-6 (6 B variant and 6 C variant) were built at Hitachi, Japan between 1987 and 1988. they along with WAG-6A were the most powerful locomotives in India until the arrival of the WAG-9 class.

All locomotives of this class have been withdrawn from service, with 1 unit from each variant earmarked for preservation.

History 
The history of WAG-6A begins in early 1980s with the aim of addressing the shortcomings of the previous WAG-1, WAG-2, WAG-3, WAG-4 and WAG-5 classes and remove steam locomotives from IR by a target date of 1990. The WAG-5 were a great successes but these locomotives were based on 1960s technology and fast became underpowered for the expanding Indian railways. So Indian Railways decided to look for a new locomotive. At that time (1980s) Thyristor controller was vastly used by locomotive in many European rail networks while 3 Phase AC technology was still in its infancy. So the ministry of railways floated a tender for a 6000HP locomotive with Thyristor control. The following responses were received:

 Hitachi submitted their model with 6000 hp with Bo-Bo-Bo bogies and Thyristor chopper control
 Hitachi also submitted their model with 6000 hp with Co-Co- bogies and Thyristor chopper control
 ASEA submitted their model with 6000 hp with Bo-Bo-Bo bogies and Thyristor chopper control.

Each company submitted their prototypes and Indian Railways designated these prototypes as the WAG-6B class WAG-6C class and WAG-6A class respectively. IR ordered 6 of each class and these were delivered in 1988.

Eastern Cables Limited. Eastern Cables Limited () is a Bangladesh government owned telecom equipment and wire manufacturing company. Eastern Cables is the largest manufacturer of cables and conductors in Bangladesh. Md. Shahidul Hoque Bhuia ndc is the chairman and Md.Abul Kalam Azad is the managing director of Eastern Cables. It is a subsidiary of Bangladesh Steel and Engineering Corporation.

History
Eastern Cables Limited was established in 1967 in Patenga, Chittagong and commercial production began on 1 March 1971. It was listed in the stock exchange in 1986. In 2008, Bangladesh governments attempts to privatize Atlas Bangladesh, Eastern Cables, National Tubes, and Usmania Glass Sheet Factory were stopped after employees of companies challenged the decision in court.

In May 2018, Dhaka Stock Exchange downgraded the Eastern Cables Limited company from "A" category shares to "Z" category shares for failure to hold regular Annual General Meeting. The same month BRB Cable Industries Limited, a private cable manufacture, bought 30 percent of the shares of Eastern Cable from the stock market despite attempts by the Ministry of Industries to stop the sale. The Ministry of Industries asked Bangladesh Securities and Exchange Commission to prevent BRB cables from taking a director seat in the company as they identified BRB cables as a competitor. The government of Bangladesh owns 51 percent of the share while the rest are in the capital market.

From 2018 to 2019, the earnings of Eastern Cable were down 229 percent.

Ecotron. An Ecotron is an experimental instrument in ecology consisting of a controlled environment which makes it possible to simultaneously condition the environment of natural, simplified, or completely artificial ecosystems and measure the processes generated by living beings present in these ecosystems, in particular the flow of matter and energy.

Design 
Its principle is to confine ecosystems in totally or partially waterproof enclosures which are permeable to energy flow and capable of generating a range of physical and chemical conditions applied to terrestrial or aquatic ecosystems, continental or marine. Environmental control and real-time measurements are precise enough to test hypotheses or operating models. For this purpose, the enclosures are fitted with significant equipment allowing continuous measurement of fluxes, states or biological characteristics. Other specific measurements, in situ and ex situ, on samples taken complete these online measurements. A sufficient number of independent confinement chambers is necessary to study several interacting factors in a framework of statistical inference.

Depending on the case, we speak of a macrocosm when the space is large enough to study several m3 of reconstituted ecosystem over a period of time, generally measured in years (3-5 years or more for example), of microcosm for volumes measuring in cubic decimeters (study of fungal, bacterial, soil ecosystems, etc.) and mesocosm for intermediate situations.

Northrop N-1. The Northrop N-1 (Northrop Model 1) was a projected flying wing medium bomber designed by Jack Northrop.

Design and development
The N-1 was a development of an earlier flying wing bomber concept from 1937, when Jack Northrop worked for Douglas Aircraft Company at El Segundo, California. This concept featured a fuselage that protruded forward of the leading edge of the wing, two pusher propellers, and vertical stabilizers on the tips of the wings. Its engines were never specified, but its defensive armament was to consist of a nose and tail turrets. A wind tunnel model of the concept was built and tested, but the project was abandoned shortly after Northrop left Douglas.

Northrop continued work on the bomber after he formed his own company, Northrop Corporation, in 1939. In response to the United States Army Air Corps' XC-219 specification, which called for a new high-altitude medium bomber, Northrop made several major changes to the design, and gave it the model number N-1. The wing was now thicker, and the separate fuselage structure was dispensed in favor of incorporating the crew compartments into the airfoil. The vertical stabilizers were replaced with drooped wingtips with an anhedral of 35 degrees, which were apparently found to stabilize paper planes during tests conducted by Jack Northrop, his son John, and Moye Stephens on a stormy weekend. Details of the design varied greatly as the aircraft evolved, with an early version featuring a large greenhouse canopy and a single vertical stabilizer under the fuselage to act as a propeller guard. There were originally planned to be seven crew, later reduced to four, including two gunners manning forward-firing guns in the nose.

Later, the stabilizer was deleted, with the anhedral of the wingtips increased to 40 degrees to make up for it, and a retractable tail wheel was added as a propeller guard instead. The greenhouse canopy was replaced with a bubble canopy protruding from the top of the wing. Defensive armament was to consist of four remotely operated turrets; one on the top and one on the underside of each wing.

The proposed powerplant of the N-1 was originally a pair of Pratt & Whitney X-1800 liquid-cooled H24 engines. When development of the X-1800 ended in October 1940, Northrop proposed that the N-1 be powered by either the Pratt & Whitney R-2800 Double Wasp or the Lycoming XH-2470.

Although Northrop never received a contract to build the a full-scale N-1, the company did build a flying mockup as the N-1M. The N-1M was used mainly for research, but also served as the forerunner of the larger Northrop YB-35 and YB-49 bombers.

Credo BC 11. Credo BC 11 is of Hungarian minibus production from 1999 to 2001 with a length of 9.5 m and 10.7 m. Buses were equipped with 176 kW Iveco Tector engines. They had drum brakes of the Rába 501 type at the front of the vehicle and the Rába 106 at the rear. There was no low-floor version of these buses. The bus is very similar to the Credo EC 11 type bus, both externally and internally. It differs only in the number of doors. There are one single-leaf door in the front and rear of the vehicle and one double-leaf door in the middle of the vehicle. They started to be delivered to Bratislava at the end of 1999 under the name SOR B9.5.

Description 
The body of the bus is panel and semi-self-supporting, its skeleton is made of steel and is welded to the bus chassis. There is one single-leaf door in the front and rear of the vehicle and one double-leaf door in the middle of the vehicle for boarding and alighting passengers, which are also used for boarding with stroller or wheelchair. The door operates on a pneumatic drive from ISAF. The interior of the bus is covered with a non-slip floor. Ventilation is provided by ceiling fans and heating by hot water radiators.

All vehicles have the BUSE information system installed to report stops with a red LED display. The first three series of this bus were equipped with a digital clock in the driver's cab, but their time was distorted, as the clock was not connected to the on-board computer. Since the fourth series, all buses have been equipped with yellow bands in the front of the bus, which defined the forbidden space for passengers to stay. Since the sixth series, all buses have been equipped with a stop reporting system. From the seventh series, the buses began to be equipped with another folding seat in place for a stroller.

Buses in Bratislava 
The bus operated in Bratislava on the lines: 23, 30, 35, 41, 42, 51, 52, 54, 56, 57, 65, 69, 75, 79, 90, 123, 144, 201 (ZV), 203 (ZV), N37, N44, N47, N56 a N72

WAGR RA class (diesel). The RA Class are diesel locomotives built by English Electric, Rocklea for the Western Australian Government Railways between 1969 and 1972. They were a revised version of the R class.

Description
The RA class were a hood type general purpose diesel-electric locomotive. They were similar to the Queensland Railways 1300 class. All equipment, except traction motors, were interchangeable with the standard gauge K class. The main differences with the R class were a slight increase in length and wheelbase and deletion of the dynamic brake. They were otherwise identical mechanically and electrically.

The bogies were identical to those fitted to the R class and were an English Electric design with low weight transfer characteristics. They feature fully equalised primary spring gear, all traction motors in each bogie mounted with the nose-suspension facing inwards, traction thrust at near axle level and long pivot centres to reduce inter-bogie transfer. Adhesion loss at maximum tractive effort is limited to 4.5 per cent allowing  trailing load to be hauled up a 1 in 100 grade.

History
Following on from the R class, a further 11 were ordered, but without dynamic brakes. A further two were financed by the Lefroy Salt Company for use over a  spur off the Esperance line.

In 1973, a version of the RA class with a low nose was ordered for Tasmanian Government Railways, which classed them Z.

In 1974 the RA1914, RA1917 and RA1918 were fitted with standard gauge bogies and renumbered KA211-KA213. RA1918 has been preserved by Rail Heritage WA.
