The investigation of cutcumber softening can be traced back to the turn of the centuiry when Aderhold (1899) described a sporeforming organism, which he called Bacterium coli, as the cauise of this spoilage. Kossowicz (1908), however, implicated the genus Bacillus and further work by Rahn (1913), LeFevre (1919), and Joslyn (1929) confirmed and extended this theory. Fabian and Johnson (1938) con...

This article applies nonlinear programming techniques to optimize humidification-dehumidification (HD) desalination cycles for operating conditions that result in maximum gained output ratio (GOR). Closed air open water as well as open air open water cycles, each with either an air or a water heater, were considered in this analysis. Numerical optimization resulted in a substantial increase in ...

Elevated atmospheric CO2 concentrations ([CO2]) have been hypothesized to increase photosynthesis rates and volatile organic compound (VOC) emissions; however, field measurements from a select group of conifer and angiosperm trees have shown that VOC emissions are in fact not affected or reduced by elevated CO2 levels. To broaden the understanding of how different plant species respond to eleva...

The present study was conducted to ascertain the ability of Dracaena sanderiana ‘Victory’, a foliage plant species of commercial importance in both domestic and international markets, to thrive under contrasting light environments. The experiment was carried out inside a semi-open greenhouse in Peradeniya, Sri Lanka. Same sized and same aged, ready-to-ship export quality plugs of Dracaena sande...

This paper presents investigations into the performance of openset, text-independent speaker identification (OSTI-SI) under mismatched data conditions. The scope of the study includes attempts to reduce the adverse effects of such conditions through the introduction of a modified parallel model combination (PMC) method together with condition-adjusted T-Norm (CTNorm) into the OSTI-SI framework....

Nitrobacter agilis, grown through seven transfers heterotrophically in the absence of nitrite, was examined in the electron microscope. The ultrastructure of such cells closely resembled that of autotrophically grown N. agilis. It was thus futher established that the organisms growing heterotrophically were indeed N. agilis and, therefore, that N. agilis is a facultative autotroph. Acetate inco...

Trichomonas vaginalis isolates NYH 286 and IR 78 were grown in continuous flow culture conditions in a complex trypticase-yeast extract-maltose medium supplemented with heat-inactivated horse serum. Parasites could be stably maintained in the chemostat at high densities ranging from 1 x 10(6) to 1 x 10(7) organisms ml-1. Growth densities, acid production, and profiles of total versus secreted t...
