Context paragraphs:
Singur Tata Nano controversy: Tata Nano Singur Controversy refers to the controversy generated by land acquisition of the proposed Nano factory of Tata Motors at Singur in Hooghly district, West Bengal, India.

Girish Wagh: Girish Wagh is currently the Head, Commercial Vehicle Business Unit.  He earlier worked in the capacity of Sr.  Vice President(Tata Small & Passenger Car Segment) & Head Project Planning and Program Management of Tata Motors.  He is a key figure in the Tata Nano's project.

Honda CR-V (third generation): The third generation Honda CR-V was launched for the 2007 model year.  It went on sale in the US during late September 2006.  Unlike preceding models it features a rear liftgate rather than a side-opening rear door and no longer has the spare tire mounted on the rear door.  The new CR-V is lower, wider, and shorter than the previous models; the length decrease is attributed mostly to the fact that the spare wheel no longer adds length to the back of the vehicle.  A lowering of the center of gravity is another benefit of the spare wheel being located underneath the rear cargo area.  The center rear seat pass-through was also introduced as a new feature on the third generation.

Rane (Madras): Rane (Madras) Ltd is a part of the Rane Group of Companies involved in the manufacture and distribution of steering and suspension systems.  The main components manufactured by the company include Manual Steering Gear Products (SGP) and Suspension & Steering Linkage Products (SSLP).  The other products include tie rod assemblies, drag link assemblies, center link assemblies and gear shift ball joints.  Automobile companies that use its products include Ashok Leyland, Volvo, M&M, Tafe, Tata among many others.  Tata motors remains its major customer and is the primary parts manufacturer for Tata's Nano.  The company has also set up a dedicated plant for Tata Nano in Sanand, Gujarat.  The company was forced to change its manufacturing facility from West Bengal to Gujarat after Tata moved out.

Tata GenX Nano: Tata GenX Nano (a.k.a. Nano GenX and Nano GenX AMT) is a city car manufactured by Tata Motors.  GenX Nano is developed from Tata Nano with an automated manual transmission and a fifth door (open-able hatch).  GenX Nano comes in 4 & 5 gear manual transmission and the 5 gear transmission system in GenX (AMT version) is the same as in Tata Zest diesel AMT.

Tata Nano: The Tata Nano is a city car manufactured by Tata Motors.  Made and sold in India.  The Nano was initially launched with a price of one lakh rupees or , which has increased with time.  Designed to lure India's burgeoning middle classes away from motorcycles, it received much publicity.

Hatchback: A hatchback is a car body configuration with a rear door that swings upward to provide access to a cargo area.  Hatchbacks may feature fold-down second row seating, where the interior can be flexibly reconfigured to prioritize passenger vs. cargo volume.  Hatchbacks may feature two- or three-box design.

Tata Pixel: The Tata Pixel is a rear-engined four-passenger city car, unveiled on 1 March 2011 by Tata Motors at the 81st International Motor Show in Geneva and aimed primarily at the European market.  It is based on the Tata Nano platform.

Sabyasachi Sarkar: Sabyasachi Sarkar ( born in 17 May 1947) is an Indian Chemist.  He has explored chemistry passionately as a prospector to observe closely the clandestine activities of nature.  He has worked and continued working in the diverse branches of chemistry closely related to natural set up and as such his research embraces functional models related to hyperthermophilic to mesophilic metalloproteins enriching bioinorganic chemistry.  A Replica of a Fishy Enzyme and the reduced xanthine oxidase also have been made.Inhibition patterns in the Michaelis complex of low molecular weight hepatic sulfite oxidase model complex have been exhibited.  Based on functional mimicking of a series of molybdoenzymes he showed that the even in model enzymatic oxotransfer reactions the participation of similar enzyme-susbrate (E-S) complex is a real entity.  Such a chemical spices( E-S) responds to spontaneous intramolecular oxidative addition and reductive elimination to complete the oxotransfer reaction.  Such a reaction differs from conventional chemical oxotransfer reaction where the reaction between the starting reactants happens in Eyring activated complex.  He demonstrated that carbon dioxide molecule does bind to magnesium in chlorophyll in photosynthesis as proposed by R. M. Willstätter hundred years ago and modeled hydrogenase captioned as better than nature.  The rare reaction of a Cu(II) complex with aerial oxygen to generate superoxide anion and Cu(III) has been shown addressing the native SOD reaction.  Similarly the aspect of copper-molybdenum antagonism in ruminant animals have been investigated.  His research has shown the architectural marvel in silk cocoon with the natural thermostatic and humidity control with preferential oxygen gating inside cocoon as green house architecture.  He proposed a new magneto reception mechanism for nocturnal moth in sensing the Earth's magnetic field to navigate with a stable pool of carbon-centric free radicals along with ferromagnetic components.  He extended the work on nano carbon and developed cheap sources of water soluble nano carbon including naturally formed graphene oxide from low grade coal.  These are used in the growth of young plants as promoters to slowly release micro nutrients and adsorbed water.  He explored these to explore bio-imaging and demonstrating that non-toxic carbon nano onion can cross blood brain barrier to carry drug as cargo and can be effectively be excreted from the body.The utility of such nano carbon to control mosquito breeding in preventing mosquito vectors of infectious dieseaes and the use of reduced graphene oxide to prevent hospital pathogens have been demonstrated.  On the environment aspect the presence of damaged floating carbon nano tubes in aerosols is shown to contribute global warming, winter smog and elevating breathing problem.  He demonstrated the adverse effect of soap and detergent discharge near tube well in releasing arsenic and fluoride contaminated water.  He also mapped the degradation of Heritage monument, Taj Mahal.

Indovation: Indovation (an abbreviation of ‘Indian innovation’) is the process by which innovations are developed in India to serve a large number of people affordably and sustainably in response to conditions of scarcity and diversity.  The individual solutions generated by this process are called indovations.  The key idea is that poverty is the mother of innovation: reduced circumstances (of the kind found in India) lead to increased effort, creativity and productivity, as reported in the practice of Jugaad among India's rural poor.  Examples of indovations include the Tata Nano, the Tata swach water filter, Devi Prasad Shetty's affordable cardiac care hospital, the SELCO's solar lighting solutions for consumers off the electricity grid and The First Identified Inexpensive Solar Water Filter was designed and invented by Shripad Krishnarao Vaidya, of Nagpur, Maharashtra, India on 23 April 2010.  The Specialty of the water filter is Capillary Pumping Technique.
