To identify parameters that can be used for the analysis of natural variation in leaf senescence of wheat; and to understand the association between the onset and progression of leaf senescence with N uptake and root traits. Chlorophyll content and the proportion of yellow leaves were used as senescence indicators and their relation with other morphological(More)
Chromium (Cr) is one of the most common heavy metals affecting the soil quality which is introduced into the environment from industries such as leather tanning, electroplating and inorganic pigment (green, orange and yellow) production. The leather industry is the major source for the environmental influx of Cr. Cleaning up of the Cr contaminated sites is(More)
Phytoremediation of soils contaminated with heavy metals has received considerable attention in recent years. Because of the contamination of food and vegetable crops with heavy metals, greater emphasis has been given to the cultivation of floriculture plants for remediation of the contaminated soils. In the present experiment, the response of rose to soil(More)
Agave americana was evaluated for its tolerance to different levels of Cr (0, 25, 50, 100 and 200 mg kg−1 soil) and its suitability for the remediation of Cr contaminated sites. The pot culture experiment was carried out for 3 months in clay soil which was collected from 0 to 30 cm depth from the nearby agricultural field. The partitioning of Cr between(More)
Optimization is a technique through which better results are obtained under certain circumstances. In the present study maximization of heat transfer through fin arrays of an internal combustion engine cylinder have been investigated, under one dimensional, steady state condition with conduction and free convection modes. Traditional methods have been used,(More)
Experiments were carried on in the Wistar rats having self-stimulation (SS) electrodes implanted chronically in substantia nigra-ventral tegmental area (SN-VTA) to examine whether modulations of GABAergic, serotonergic, histaminergic, dopaminergic, and glucocorticoid neuronal receptor functions will affect or not the brain reward system and the SS(More)
