Although a plethora of synthetic procedures mediated by KF-loaded aluminas is available in the literature, there is almost no data concerning the influence of parameters such as alumina modification or KF-loading on experimental results. Hence, the Pd-catalyzed, solvent-free Suzuki-Miyaura reaction was chosen as model reaction to investigate the effect of the above mentioned parameters on the r...
Aqueous-phase diffusion in geologic media is very important in agricultural production, contaminant transport and remediation, risk assessment, and waste disposal. This review was undertaken to investigate (1) the components of effective diffusion coefficients, (2) diffusion as a function of water content and diffusion models, as well as the effects of temperature, compactness, and sorption on ...
Drought affects yield of peanut, but its effect on oleic and linoleic acids that influence its oil quality of peanut genotypes with different levels of drought resistance has not been clearly investigated. Therefore, the aims of this research were to determine whether soil water levels could affect oil quality by changes in fatty acid compositions of peanut, and to investigate the changes i...
conclusions the fluoride content of drinking water in reservoirs and at homes was below the optimal level in mariwan. no differences were observed from the standard levels in behbahan. there were no differences in fluoride content of water in reservoirs and in home pipelines, indicating no tangible changes in fluoride content from the reservoirs to the homes. in neither of the towns was severe ...
water stress decrease water content and water potential between soil and root. therefore, water potential of plant declines and plant faces with water stress. water stress in different stages of growth can be useful in different aspects. water stress can be practiced from two point of view, increasing water use efficiency (wue) and improving cultural practices. no irrigation in insensitive sta...
There is considerable disagreement as to whether or not water is equally available to plants in drying soil over the entire range from field capacity to wilting percentage. Some workers have repeatedly stated that water is equally available over this range (5, 18, 23, 24) while considerable data have accumulated which indicate that physiological processes in plants are altered as a result of de...
Studies show that the performance of soil water content monitoring (SWCM) sensors is affected by soil physical and chemical properties. However, the effect of organic matter on SWCM sensor responses remains less understood. Therefore, the objectives of this study are to (i) assess the effect of organic matter on the accuracy and precision of SWCM sensors using a commercially available soil wate...
water desorption isotherms of raw and osmotically dehydrated (at 25ºc, for 2 hours, with 10 and 26% nacl solutions) garlic slices at different temperatures (25, 40, 55, and 70ºc) were experimentally determined over a range of water activity of 0.05–0.90 using a static gravimetric method. desorption isotherms can be classified as type iii. the water desorption isotherms of raw garlic clearly sho...
