Sodium and fluid retention in dialysis patients is associated with hypertension and vascular changes that may ultimately lead to serious cardiovascular complications. Achieving and maintaining dry weight appears to be an effective but forgotten strategy in controlling and maintaining normal blood pressure among hypertensive patients on dialysis. A crucial question is how to determine 'dry weigh...

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

Cell death in a resting population of an asporogenous Bacillus megaterium was accelerated by ambient concentrations of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) equal to or greater than 10 ,ug/ml or 5 ,ug/mg of cells (dry weight), but only after prolonged exposure. Conversely, populations of growing cells were not markedly influenced even at 100 gg/ml. Effects on cell respiration were not man...

a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...

Changes in dry weights, reduced N, nitrate, and nitrate reductase activity of various plant parts of the above ground vegetation (stover) and ears of field grown maize were measured at intervals between anthesis and grain maturity. Nonstructural carbohydrate contents were also measured in some instances. Changes in dry weight and reduced N content were used to approximate net in situ photosynth...

Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...

the objective of this research is to investigate the effect of four additives including iron slag (is), works debris (wd), fly ash (fa), and lime kiln dust (lkd) on the biochemical properties of biosolids produced at mangere wastewater treatment plant (mwwtp), auckland, new zealand. all these additives are homogenously mixed in the laboratory with biosolids at various percentages with and witho...
