Amectran Exar-1. The Amectran Exar-1 was an electric sports car prototype developed by Edmond X. Ramirez, Sr. in 1979. The prototype was built by the Italian Designer and coachbuilder Pietro Frua. The car was advertised by Amectran to be the "world's first production, electronic powered automobile". The car was highly praised before the prototype was finished by the United States Secretary of Transportation. Unfortunately, the vehicle did not develop beyond a single prototype. Originally, BMW commissioned Pietro Frua to design the 1975 3.0Si concept for a 1975 autoshow. A few years later, he would reaquire the concept car and make minor changes to the car to support new electronics and a battery at the front. He then sent this chassis to Ramirez in Texas who began making it fully electric.

Jaipur Development Authority. Jaipur Development Authority (JDA) is the agency of the Government of Rajasthan responsible for preparation and implementation of master plan for the Jaipur city in Rajasthan state in India. It is engaged in infrastructural and basic amenity development for Jaipur and also environment conservation and development of rural areas around the city.

JDA has its head-office at JLN Marg, opposite the famous Birla Mandir, Jaipur.

Projects 
The Dravyavati River rejuvenation project was approved in 2015, awarded to a consortium of Tata Group and the Shanghai Urban Construction Group with an initial cost of over 131 crore Rupees to complete the work by October 2018. The estimated ten-year project cost, covering construction, operation and maintenance, was over 150 crore Rupees.

The Jaipur Ring Road project, first conceived of in 2000, is for a six-lane expressway encircling the Jaipur city. The contract, worth 900 crore Rupees, was awarded in May 2011.

Criticism 
Protests have taken place in Nindar against the compensation being offered for a proposed housing scheme. Farmers have been burying themselves neck-deep or going on hunger strike. The housing scheme is supposed to construct up to 10,000 homes.

The Dravyavati river is being constructed by capturing the private land of the poor farmers situated by the JDA at Goner village. The farmers are entitled to 25% compensation from the JDA in respect of this land, but JDA is constructing a Dravyavati river on the farmers land without paying any compensation to farmers. When the farmers ask for compensation from the JDA, they are intimidated by them and the JDA  refused to compensate them by referring to the state government project (CM). The farmers resorted to the court with this attitude of the JDA and the court has taken stance that as long as the farmers will not get any compensation, JDA can not work on their private land. The JDA however has not ruled the court's order and its arbitrariness is being done. Despite the court's position, the JDA is (continuing) to make the Dravyavati river on the private land of farmers.

Dornier Do 14. 

The Dornier Do 14 was a prototype seaplane, developed by Dornier Flugzeugwerke with backing from the Luftwaffe for experimental propulsion studies. The aircraft was similar to the Dornier Do 12. Only one Dornier Do 14 was constructed for testing, the aircraft registered as "D-AGON", after test flights during 1936, the aircraft engines were subsequently dismantled in 1937. The prototype aircraft was finally scrapped in 1939.

Arado Ar 198. The Arado Ar 198 was a prototype reconnaissance aircraft, developed by Arado Flugzeugwerke, with backing from the Luftwaffe, who initially preferred it over the Blohm & Voss BV 141 and the Focke-Wulf Fw 189. However, when flight tests were carried out the aircraft performed poorly and did not impress the Luftwaffe. One aircraft was completed in 1938.

Design and development

In 1936, the RLM issued a specification for a new aircraft that would specialize in short-range reconnaissance, with special emphasis placed on ground vision. Arado, Blohm & Voss (Hamburger Flugzeugbau Division), Focke- Wulf, and Henschel all had experience with this specific type of aircraft and started work immediately.

The Ar 198 was to be built around a three-man crew, consisting of a  pilot, gunner/radio operator, and observer. Both the pilot and gunner/radio operator positions were above the wing, while the observer's area was below the wing, in a well-laid-out fuselage that offered good communication between the crew members.

Built using a shoulder wing configuration, giving the pilot unrestricted forward visibility, the Ar 198 was of steel tube construction for the forward fuselage structure with all-metal monocoque construction of the tail boom.

An air-cooled radial BMW 132 engine was initially chosen, but due to availability concerns, the first prototype was fitted with the slightly lower-powered Bramo 323 A-1 of the Brandenburgische Motorenwerke.

Operational history

In early March 1938, the Ar 198 made its first flight from the factory airfield at Warnemünde. Following flights proved generally satisfactory, except for instability in all axes during low-speed flight. Automatic slats were fitted with noticeable improvement, but It was still a difficult craft to handle.

Basic poor performance and concerns about insufficient production capacity led the Technical Office to terminate the development of the Arado Ar 198 in the latter months of 1938.

Arado E.340. The Arado Ar E.340 was a twin-engined dive- and tactical-medium bomber, designed by Arado Flugzeugwerke at the request of the Reich Air Ministry in 1939 to compete for a production contract for the Bomber B fast bomber design competition, but the project was cancelled.

Design and development
The Reich Air Ministry ordered the aircraft to replace the Junkers Ju 88 and Dornier Do 217 bombers by 1943. Four manufacturers submitted plans to the Air Ministry, which chose the Arado design. The engines were positioned in a unique twin-boom arrangement connected only through the wing assembly, a configuration which offered the crew better visibility.

The Arado E.340 was designed with a central fuselage containing all four crew members. The cockpit and rear compartment were glazed and pressurized. The Jumo engines and landing gear were mounted to the load-bearing wing centre-section. The tail of the aircraft was a unique design, where the tailplane did not connect the two booms but was cantilevered outwards instead, each similar to the asymmetric BV 141B booms and tail arrangement. Also similarly, this would have provided the rear gunner with a clear range of fire directly behind. The fuselage extended forwards beyond the engines, with the gunners situated behind the cockpit, ahead of the bomb bay and wing spars. The MG 151 cannon in the tail of the central fuselage would have been controlled with remote aiming through periscopes. There were also two remote-controlled Fernbedienbare Drehlafette FDL 131 13mm gun turrets to be placed above and below the fuselage.

The E.340 was one of the steadily growing number of later-war military airframe designs designed to use the troublesome Junkers Jumo 222 engine. Otherwise an innovative design, these powerful engines were selected because they would have allowed the Arado E.340 to carry the required payload of  within a relatively compact airframe, despite their still-strictly developmental nature. As the engines were cancelled, the project would likely have failed due to the lack of engines of suitable power, and could have struggled with the amount of high grade fuel needed to power them. Ultimately, the entire Bomber B project was cancelled, primarily as a result of the failure to develop the required engines.

Fieseler Fi 333. 

The Fieseler Fi 333 was a prototype transport aircraft developed by Fieseler in 1942, and backed by the Luftwaffe.

Design and development 
The aircraft was to use detachable pods of varying sizes to carry cargo, a system that would allow a rapid turnaround on the ground. The tall, fixed undercarriage featured tandem independently sprung wheels.  Power was provided by two  BMW Bramo 323D radial engines.

Three prototypes are believed to have been built.

Arado Ar 69. The Arado Ar 69 was a two-seat German beginner's school and sport biplane with an open cockpit, developed in 1933 by Arado Flugzeugwerke.

Design & development
Three prototypes were built, the Ar 69 V1 and Ar 69 V2 were powered by  Hirth HM 504A engines and the V3 was powered by a BMW Bramo Sh.14a radial engine. Featuring swept wings constructed from wood, and a welded steel tube fuselage, the V1 and V2 represented the planned Ar 69A production aircraft, and the V3 would have evolved into the Ar69B production model. No production aircraft were built, due to the success of the rival Focke-Wulf Fw 44 Stieglitz.

Nitromors. Nitromors (formally "Nitromors Master Craftsman's Paint And Varnish Remover") is a paint-stripping chemical intended for do-it-yourself use. It is manufactured in the U.K. by Henkel Consumer Adhesives of Winsford, Cheshire.

The original product, up to circa 2006, came in two versions - "All Purpose" and "Master Craftsman". The active and main ingredient of both the original Nitromors versions was dichloromethane (also known as methylene chloride) accompanied by a smaller proportion of methanol. This product was recommended by the Guild of Master Craftsmen and the Guild's logo appeared on the tin. 

The pre-2006 version was certified for safety, as is the post-2006 version.

The current All Purpose version of the product, as of 2011, does not contain any of the active ingredient dichloromethane, and the logo representing approval by the Guild of Master Craftsmen no longer appears on the tin.

The instructions for use of all the versions of the product indicate that great care should be taken to work in a well-ventilated area, preferably outdoors, because there are health risks from the fumes.
