  • Early interest in selenium by nutritionists concerned its high concentration in certain range plants and the consequent toxicosis in animals that grazed those plants. More recently, the essential nature of selenium has become the center of attention, and this element is now known to be required by laboratory animals, food animals (including fish), and humans. Its role as an integral feature of glutathione peroxidase has been established, and other possible functions are under active investigation.

  • This book has its conceptual origin from the lecture materials of the training courses taught by one of the authors in the early nineties. It was during this period that in several developing nations, particularly in Africa, even when the signs of widespread hunger and abject poverty were visible, policy makers did not act for want of ‘empirical evidence’. Some policy makers even dismissed the severity of the problem saying that the hunger reports prepared by government officials were not rigorous enough to take them seriously.

  • The third edition is divided into five parts. Part one describes some important basic concepts. Part two describes unit operations that take place at ambient temperature or involve minimum heating of foods. Part three includes operations that heat foods to preserve them or to alter their eating quality. Part four describes operations that remove heat from foods to extend their shelf life with minimal changes in nutritional quality or sensory characteristics. Part five describes post-processing operations, including packaging and distribution logistics. ...

  • small water bodies like ponds now contributes 80% of the country’s inland fish production. However, future growth in freshwater aquaculture to meet rising demand for fish is likely to be constrained by limited supplies of land for digging new ponds and of water to fill them. In this context, reservoirs offer immense scope for increasing fish production.

  • A plant nutrient is a chemical element that is essential for plant growth and reproduction. Essential element is a term often used to identify a plant nutrient. The term nutrient implies essentiality, so it is redundant to call these elements essential nutrients. Commonly, for an element to be a nutrient, it must fit certain criteria. The principal criterion is that the element must be required for a plant to complete its life cycle. The second criterion is that no other element substitutes fully for the element being considered as a nutrient.

  • World cocoa price has fallen by some 48% over the past three years, with direct impacts on the incomes, health and nutrition of cocoa producers and their family in the two major producing countries: Côte d’Ivoire and Ghana, with some 41% and 22% of world output, respectively. The impact of the price drop has been far different in the two countries because of the greater age of plantations, market liberalisation, presence of free agents in the marketing channel, and much greater socio-political instability in one country: Côte d’Ivoire.

  • The Hypothalamushypophysis- gonadal (HPG) axis is subject to both positive feed-forward and negative feedback regulation at several levels. At the level of the hypothalamus, early recognition of the pulsatile nature of gonadotropin releasing hormone secretion led to the notion of a central ‘‘pulse generator”, the inherent oscillatory activity of which controls the secretory rhythm of GnRH neurons (Knobil, 1980).

  • Some results of indoor particulate (PM) concentrations measurements in relation to type of stove and fuel from Latin-America are presented in table 2.1. The improved stoves, such as the plancha, produce PM 2.5 or PM 3.5 levels that are often only 20 percent of concentration levels from an open fire, and are even found to be less than 10 percent of that of an open fire in a study in Guatemala by McCracken and Smith (1998). The reduction in PM 2.5 seems to be even larger than reductions in PM 10. However the concentration levels...

  • This study has also consulted other documents published elsewhere, such as Sarma (1986) and Mink (1987). Sarma (1986), a Research Report published by IFPRI (Washington), is concerned with the analysis and projections (to 2000) of use of cereals for livestock feed in developing countries. Mink (1987) has addressed the use of corn in livestock feed and the future of the corn economy in Indonesia. The study focussed on current levels of corn use and likely future growth of corn-based livestock feeds in Indonesia.
