The Freundlich model was evaluated for use to assess the effect of heat on the adsorption capacity of an activated carbon for decolorizing/deodorizing corn zein. Because zein protein and its color/odor components are all adsorbed by activated carbon, a method to monitor their removal was needed. Yellow color is due to xanthophylls; a contributor to off-odor is diferuloylputrescine. The off-odor...

When Kalanchoe Blossfeldiana is exposed to repeated short-days there is a marked increase in both the amount and the rate of the fixation of carbon dioxide in the dark (3). Plants which have received a series of short day and long night cycles show an uptake of CO2 in each dark period which begins slowly, increases to a maximum and falls again; finally it reaches zero and is followed by a brief...

Coral bleaching involves the detachment of zooxanthellae and the simultaneous fragmentation of the gastrodermis. Results obtained with a cell permeant fluorescent probe for calcium ions (Ca2+) indicates that “thermal” bleaching is the result of a temperature related breakdown of the Ca2+ exclusion system. “Solar” bleaching, which takes place at lower temperatures and is driven by light, is the ...

Run off resulted from rainfall is the main way of receiving water in most parts of the World. Therefore, prediction of runoff volume resulted from rainfall is getting more and more important in control, harvesting and management of surface water. In this research a number of machine learning and data mining methods including support vector machines, regression trees (CART algorithm), model tree...

Spectroscopic temperature measurements using coherent or incoherent light sources coupled to optical spectrometers have been accomplished by measuring the distribution among the quantized energy levels of a given sample, for example the ro-vibrational intensities of a molecule [1]. Moreover, the dependence of the experimental spectrum on temperature and pressure is also observed via line-shape ...

One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months. The sampling was accompl...

Reproduced by the permission of ECS – The Electrochemical Society leakages to fuel system will retain the anode in oxidized state. Moreover, some performance loss was measured when the stack was heated to 400 C before fuel supply was started. Therefore, it is recommended that the supply of hydrogen-rich reducing gas is started already below 350 C, or as low temperature as possible, to prevent o...

The influence of a cerium additive on the kinetics of oxidation and size distribution of ultrafine diesel particles was studied using a high-temperature oxidation-tandem differential mobility analysis method over the temperature range 300–700 ◦C. The addition of cerium to the diesel fuel was observed to cause significant changes in numberweighted size distributions, light-off temperature, and k...
