Crops made resistant to herbicides by biotechnology are being widely adopted in various parts of the world. From the genesis of commercialization in 1996 to 2011, herbicide tolerance has consistently been the dominant trait. Those containing transgenes that impart resistance to post-emergence, non-selective herbicides such as glyphosate and glufosinate will have the major impact. These products...

PURPOSE To compare psychophysically determined spatial variations in photopic and scotopic sensitivity across the macula in patients with retinitis pigmentosa (RP) and normal visual acuity who manifest an abnormal high-density ring of fundus autofluorescence (AF). METHODS Eleven patients with a clinical diagnosis of RP were examined. All had rod-cone dystrophy (International Society for Clini...

Megalopolis is a group of densely populated metropolitan areas that combine to form an urban complex. Since China introduced the economic reforms in late 1970s, the Chinese urban system has experienced unprecedented growth. The process of urbanisation prevailed in the 1980s, and the process of predominantly large city growth appeared to continue through 1990s and 2000s. In this study, the magni...

Bihar has a total geographical area of 93.60 lakh hectares on which it houses population 82.9 million, thereby generating density 880 persons per sq. km (Census 2001). Gross sown in the State is 79.46 hectares, while net 56.03 hectares. There are around 1.04 crore landholdings 83 percent marginal holdings size less than 1 hectare (Table 1). With 90 living rural areas, agriculture as primary fee...

Forage sorghum is considered to be the most heat and drought resistant summer forage with a fairly high green forage yield. Forage sorghum is more economical to grow as compared to forage maize with fairly high economic returns. The total area under forages in 2012 in Punjab was 1.82 million hectares with green forage production of 38.8 million tons. The land area of Punjab under forage sorghum...

Hectares of genetically modified (GM) crops have increased exponentially since 1996, when such crops began to be commercialized. GM biotechnology, together with conventional breeding, has become the main approach to improving agronomic traits of crops. However, people are concerned about the safety of GM crops, especially GM-derived food and feed. Many efforts have been made to evaluate the uni...

Microalgae show an enormous potential as sustainable feedstock for numerous bioproducts. The current work analyzes the feasibility of business cases for different markets of products from microalgae. We perform a techno-economic evaluation of the whole process chain including cultivation, biorefinery and market exploitation for a 100 hectares facility in six locations. Our projections show a cu...
