Taschenbuch. Zustand: Neu. Neuware -In recent times many underground water supply systems have seen several technological advances. Among these technological advances is the mechanization of the well/bole hole water. In most rural settings a mechanical pump is attached to the bole hole. These pumps draw water from underground through strokes on a level system mounted at the top of the bole hole. This type of bole holes needs a lot of manual labour from the consumer and may in many cases cause undue delays to reach quality water. A typical solution to ease the consumer is the introduction of an electrical pump system. The electrical pump is supplied with a source of electricity to pump underground water through pipes fixed on the well. There is always the need to control the electrical pump and the reservoir. Various forms exist. The emergent microcontroller can be used in this water supply system as a form of the control module.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The present piece of work was done at the Agronomy field laboratory, Sher-e-Bangla Agricultural University, Dhaka. The main goal was to find out the influence of different weed control methods on the growth and yield of aromatic aman rice varieties. To determine the economic feasibility of different weed control methods on aromatic aman rice, total cost of production, gross return and net return were calculated to determine the benefit cost ratio. Twenty three weed species infested the experimental plots belonging to eleven families. The book provides detailed experiment results and practical conclusions based on in-depth research.Books on Demand GmbH, Überseering 33, 22297 Hamburg 164 pp. Englisch.
