To identify the genes responsible for yield related traits, and heterosis, massively parallel signature sequencing (MPSS) libraries were constructed from leaves, roots and meristem tissues from the two parents, 'Nipponbare' and '93-11', and their F1 hybrid. From the MPSS libraries, 1-3 million signatures were obtained. Using cluster analysis, commonly and specifically expressed genes in the par...

Two field experiments were carried out during the summer seasons of 2000 and 2001, at the Experimental station Farm, Faculty of Agriculture, Alexandria University, at Abies, to investigate the response of potato plants cv. Alpha, to two biofertilizer types (Nitrobein and Halex-2) under four varying percentages NPK; 25%, 50%, 75% and100% from the commercial recommended rates (180-60-96 Kg N-P-K ...

Studies were carried out in 2005 and 2006 raing seasons at four locations (Abakaliki, Ezzamgbo, Ikwo and Okposi) within the Abakaliki Agro-ecological zone of southeastern Nigeria, to determine their suitability for the production of lettuce. The measurements included weather elements, soil physico-chemical propertiesand crop growth and yield. The data collected were subjected to statistical ana...

Two field experiments were conducted on sweet pepper plants (cv. California Wonder) during the successive summer seasons of 2000 and 2001, in the Agricultural Experimental station, Alexandria University, at Abies. The objective of these experiments was to determine the effects of nitrogen rates (60, 90 and 120 kg fed -1 ) and their application systems (three, four, five and six split applicatio...

Several 64-bit adders have been designed and their ezpected yield has been estimated. OUT Tesults show that the yield of VLSI adders can be improved by modifying the layout of the ol.iginal design and/or by choosing a dzfferent layout and circuit structure. In certain situations, these approaches can improve the yield by 10% to 17%.

In this paper, two algorithms for layer assignment with the goal of yield enhancement are proposed. In the rst, vias in an existing layout are moved in order to decrease its sensitivity to defects. A greedy algorithm for achieving this objective is presented. In the second, we formulate the layer assignment problem as a network bipartitioning problem. By applying the primal-dual algorithmm1] (a...

The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...
