  • Soil fertility describes soil nutrient status and the factors controlling the supply of nutrients to plants. Continued efforts to improve soil fertility are required to support the world's growing demand for food, fiber, and renewable fuels. Important ecological services provided by soils, such as biodiversity, buffering capacity, and nutrient recycling benefit from the amendments applied to sustain soil fertility. Those amendments need to be applied in a manner that is both economical and practical for the producer to achieve agronomic objectives that are environmentally sound.

  • Rehydration consists not only of the ingestion of water but also of its absorption and distribution throughout the body tissues. Because of large buffering capacity of their alimentary tract, ruminants are able to drink large quantities of water in a very short time after a period of privation. Animals without this capacity are rarely able to take all their requirements in one short session, mainly due to the problems associated with haemolysis. Some non-ruminants are, however, capable of rapid drinking, including dogs and donkeys.

  • Current estimates and measurements predict that Internet traffic will continue to grow for many years to come. Driving this growth is the fact that the Internet has moved from a convenience to a mission-critical platform for conducting and succeeding in business. In addition, the provision of advanced broadband services to end users will continue to cultivate and prolong this growth in the future.

  • Duchenne muscular dystrophy represents one of the most common hereditary diseases. Abnormal ion handling is believed to render dystrophin-deficient muscle fibres more susceptible to necrosis. Although a reduced Ca 2+ buffering capacity has been shown to exist in the dystrophic sarco-plasmic reticulum, surprisingly no changes in the abundance of the main luminal Ca 2+ reservoir protein calsequestrin have been observed inmicrosomal preparations.

  • Our study aimed to investigate the acidity status of mangrove soils in the ecological shrimp system to forecast their potential acidification risks. Results indicated that there were slight increases of soil acidity. High content (>5%) of soil organic carbon (SOC) in the depth of 0 – 80 cm is one of the main contributors to soil pH buffering capacity, and may help reduce sharply soil acidity changes.

  • Concentrations of three aluminium compounds significantly affected the mycelial extension of Trichoderma viride with low pH values growing on agar media, and the largest effect was recorded with aluminium chloride. Experiments in this work showed that there were significant relationships between Al concentration and pH in the Al inhibition of fungal activity on agar media.

  • COMBINING THE BURST AND CELL SCALES The finite-capacity buffer is a fundamental element of ATM where cells multiplexed from a number of different input streams are temporarily stored awaiting onward transmission. The flow of cells from the different inputs, the number of inputs, and the rate at which cells are served determine the occupancy of the buffer and hence the cell delay and cell loss experienced. So, how large should this finite buffer be? In Chapters 8 and 9 we have seen that there are two elements of queueing behaviour: the cell-scale and burst-scale components. ...

  • A project on Community Participation for Conservation Success developed by WWF, Xuan Mai Forestry University and FPD used Khe Tran as one of the training sites in buffer zones. It was designed to increase the effectiveness of conservation programs in Vietnam by promoting community participation through community- based environmental education (CBEE). The project, started in 2003, aimed to increase the immediate and long-term capacity of government to incorporate CBEE training into mainstream training institutions.
