  • The utility of primer pairs in SCoTs was advocated by Gorji et al. (2011). SCoT markers are generally reproducible, and it is suggested that primer length and annealing temperature are not the sole factors determining reproducibility (Gorji et al., 2011). They are dominant markers, however, while a number of co-dominant markers are also generated during amplification, and thus they could be used for genetic diversity analysis (Collard & Mackill, 2009b). This has been validated through study of genetic diversity among rice varieties (Collard & Mackill, 2009b).

  • Agricultural biotechnologies apply modern knowledge in molecular and cell biology to produce new varieties and similar genetic materials. The use of genetically modified (GM) crop varieties has grown dramatically since they were introduced in 1995, and large portions of the land allocated to corn, soybeans, and cotton are grown with these varieties. The evidence from the United States, Canada, China, India, Brazil, and Argentina suggests that these applications of biotechnology in agriculture increase yield, reduce the use of pesticides, and save production costs. ...

  • In a pot experiment was conducted to evaluate the physiological characteristics and root characteristics associated with drought tolerance of rice varieties including indica rice subspecies, japonica rice subspecies, hybrid male sterility line and temperature sensitivity of wild rice species for comparison with drought-tolerant Indica rice varieties. At the effective tillering, the pot experiment was to drain the water and then dried for 4 days, then watered again.

  • The work of the dry-farmer is only half done when the soil has been properly prepared, by deep plowing, cultivation, fallowing, for the planting of the crop. The choice of the crop, its proper seeding, and its correct care and harvesting are as important as rational soil treatment in the successful pursuit of dry-farming. It is true that in general the kinds of crops ordinarily cultivated in humid regions are grown also on arid lands, but varieties especially adapted to the prevailing dry-farm conditions must be used if any certainty of harvest is desired. Plants possess a marvelous power...

  • In the past decade manufacturers and retailers have been gradually switching from above the line mass media advertising to a variety of below the line sales promotions. Although sales promotions take up a very large share of total marketing expenditure, they remain an area of less strategic consideration or attention than any other aspect of the promotion mix (Srinivasan and Anderson, 1998). The potential benefits of using sales promotions could range from giving immediacy and encouraging purchase of a product or service by changing the perceived value- for-money equation.

  • Petroleum contaminant decomposition and in-situ destruction may be accomplished using chemical oxidation technologies. In contrast to other remedial technologies, contaminant reduction can be seen in short time frames (e.g., weeks or months). As discussed in this chapter, a variety of chemical oxidants and application techniques can be used to bring oxidizing materials into contact with subsurface contaminants to remediate the contamination.

  • This book is a critical account of tropical agricultural science in the twentieth century, with its successes as well as its fads and failures. Its coverage reaches back into the beginning of the twentieth century, but the second half of the century takes place of choice. Which means that the story is closely linked with that of post-colonial development and scrutinises the role agricultural science has played (or failed to play) in the advancement of the tropical smallholder, in particular in Africa....

  • Regioregular polythiophene-based conductive copolymers with highly crystalline nanostructures are shown to hold considerable promise as the active layer in volatile organic compound (VOC) chemresistor sensors. While the regioregular polythiophene polymer chain provides a charge conduction path, its chemical sensing selectivity and sensitivity can be altered either by incorporating a second polymer to form a block copolymer or by making a random copolymer of polythiophene with different alkyl side chains.

  • Since the early 1970s, a variety of issues relating to energy supply have disrupted the energy marketplace. The oil crises of the 1970s, the deregulation of electricity and gas markets, the ebb and flow of various conflicts in the Middle East, Y2K fears, air-quality concerns, the recognition of global warming, and California’s recent energy supply woes are just some of the events and concerns that have affected both consumer perceptions and market prices.

  • On the theory side, research has proceeded along two distinct fronts. First, one needs to explain what prevents rational arbitrageurs from eliminating these and other predictable patterns in returns. Work in this “limits to arbitrage” vein has focused on the risks and market frictions that arbitrageurs face. These include simple transactional impediments, like short-selling constraints, as well as a variety of other complications.

  • This section illustrates that MBT systems can be described as two simple concepts: either to separate the waste and then treat; or to treat the waste and then separate. In some systems only biological treatment is required to treat all the residual MSW before disposal to landfill. Whilst a variety of treatment and mechanical separation options are offered, these need to be optimised in terms of the outputs in order to find outlets for the various materials / fuels derived from the process (see Markets for the Outputs section). ...
