An experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh with the cucumber cv. Modumoti to evaluate the porpho-physiological characters and yield performance under four different levels of light (100, 75, 50 and 25% PAR). Significant differences were observed among the treatments in response to different evaluated characters. Main stem length,...

Rhizopus oryzae is a filamentous fungus, belonging to the order Mucorales. It can ferment a wide range of carbohydrates hydrolyzed from lignocellulosic materials and even cellobiose to produce ethanol. However, R. oryzae also produces lactic acid as a major metabolite, which reduces the yield of ethanol. In this study, we show that significant reduction of lactic acid production could be achiev...

A fluorescent sensor for halogenated solvents termed AMN is reported. AMN shows strong fluorescence in most halogenated solvents (QE > 0.1) but weak fluorescence (QE<0.01) in most non-halogenated solvents. In chlorinated solvents, the fluorescence intensity decreased with the reduction of chlorine content. On the contrary, in brominated solvents the fluorescence intensity increased with the red...

Pesticides pose serious threats to both human health and the environment. In Europe, farmers are encouraged to reduce their use, and in France a recent environmental policy fixed a target of halving the pesticide use by 2018. Organic and integrated cropping systems have been proposed as possible solutions for reducing pesticide use, but the effect of reducing pesticide use on crop yield remains...

This study used non-invasive pulse-amplitude modulated (PAM) fluorometry to measure the maximum fluorescence yield (F(v)/F(m)) of two Hawaiian scleractinian coral species exposed to short-term sedimentation stress. Beach sand or harbor mud was applied to coral fragments in a flow-through aquarium system for 0-45 h, and changes in F(v)/F(m) were measured as a function of sediment type and length...

In recent years the use of 2,4-dichlorophenoxyacetic acid (2,4-D) as a selective herbicide has become increasingly important in the production of small grains and corn. Yield reductions due to direct injury to the crops are usually small. However, severe yield reductions have occurred occasionally when 2,4-D was used at herbicidal dosages during certain stages of crop growth. Corn plants spraye...

With the dramatic increase in mask costs, multi-project wafers have became an attractive choice for low-volume chip fabrication. By using the same set of masks to fabricate a number of different chips, the mask-set cost is amortized among different chip providers, leading to significant cost reduction especially for chip prototyping. In this paper we present a new algorithm for reticle floorpla...

Drought is one of the major abiotic stresses affecting wheat yield. A recurrent selection program was conducted to improve the drought tolerance and yield of bread wheat using drought tolerant advanced breeding lines from a drought tolerant x susceptible cross (HI 1500 x HUW 510). The parental lines were evaluated for yield, biomass and harvest index (HI) in addition to the drought adaptive tra...

Power consumption in VLSI systems has become a critical metric for design evaluation. Although power reduction techniques can be applied at every level of design abstraction, most automated power reduction techniques apply to the lower levels of design abstraction, such as the register-transfer or gate level. We therefore investigated the power reduction attainable by the evolving automated beh...
