Seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. Many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. Seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. Du...

with the aim of controlling malaria by reducing vector population, the effects of antibodies produced against salivary glands and deglycosylated midgut antigens of anopheles stephensi mosquitoes on fecundity and longevity of the same species were tested. three deglycosylated preparations of midgut and two preparations of salivary glands were produced, conjugated with aluminum hydroxide gel, and...

Although theories in both evolutionary biology and economics predict that an individual’s health should be associated with the individual’s time preference, no prior study has been done to empirically support or refute such predictions. By collecting detailed measures of health, time preference, and expected longevity on a sample of individuals in townships around Durban, South Africa, this stu...

Centenarians (people living to age 100 and beyond) represent one of the fastest-growing age groups of the American population, with obvious implications for actuarial science and practice. Yet, factors predicting exceptional longevity and its time trends remain to be fully understood. In this project we explored the new opportunities provided by the ongoing revolution in information technology,...

Many empirical studies have established that state dependence varies across consumers, brands, and categories. Previous analytic models have assumed that state dependence is a customer characteristic that does not vary across firms. In contrast, we take the view that state dependence varies by firm. That is, a well-known national brand, such as Tide detergent, may be able to attract more repeat...

Different genetic programs that are active during late stages of zygotic embryogenesis are involved in seed phenotypes as longevity, basal thermotolerance, and desiccation tolerance. In sunflower, Heat Shock Factor A9 (HaHSFA9) controls one of such programs, the HaHSFA9 program. Overexpression of HaHSFA9 in seeds of transgenic tobacco showed the involvement of this transcription factor in basal...

The relationship between the gyre-scale circulation of the North Atlantic, represented by air pressure near to the centre of the sub-tropical gyre, and sea level measured at the eastern boundary of the ocean has been investigated using records commencing in the middle of the 18th century. These time series are twice as long as those employed in an earlier study of this relationship. Near-contin...

The shoreline is one of the most important features on earth’s surface. It is valuable to a diverse user community. But the dynamic nature of the shorelinemakes it difŽ cult to be represented in a naturally dynamic style and to be utilized in applications.The ofŽ cially usedshoreline,for examplein nauticalcharts,is the so-calledtide-coordinatedshoreline. It is also the shoreline that makes the ...
