A note on the culture of Chanos chanos (Forskal) at Brackishwater Fish Farm, Kaninada

The culture of Chanos chanos to marketable size within a three months period, is described. Procedures involved include phased manuring coupled with proper water management to keep up enhanced primary productivity. Results show that, under monoculture, with low-input technology it is possible to produce 3,000 kg fish per hectare per year

Bit-Level Systolic Architecture for a Matrix-Matrix Multiplier

Highly efficient arithmetic operations are necessary to achieve the desired performance in many real-time systems and digital image processing applications. In all these applications, one of the important arithmetic operations frequently performed is to multiply and accumulate with small computational time. In this paper, a 4-bit serial - parallel multiplier, which can perform both positive and negative multiplications, is presented. Baugh-Wooley algorithm necessitates complementation of last bit of each partial product except the last partial product in which all but the last bit are complemented. In the proposed algorithm all bits of the last partial product are complemented. This modification results in considerable reduction in hardware compared to Baugh-Wooley multiplier. This multiplier can be used for implementation of discrete orthogonal transforms, which are used in many applications, including image and signal processing. This paper presents a 2D bit-level systolic architecture for a matrixmatrix multiplier. A comparison with similar structures has shown that the proposed structure performs better

Designing Economic Instruments and Participatory Institutions for Environmental Management in India

This paper examines the possibility of using economic instruments, especially pollution taxes and bargaining approaches, as a means to encourage or improve people’s participation in environmental management in India. It provides an intuitive description of methods for designing economic instruments and bargaining approaches. A case study describes the estimation of pollution taxes for controlling air pollution in thermal power generation in India. Another case study examining some bargaining methods that are already in force in India shows their usefulness in controlling industrial pollution.
