Changes in ionized calcium were studied in axons isolated from living squid by measuring absorbance of the Ca binding dye Arsenazo III using multiwavelength differential absorption spectroscopy. Absorption changes measured in situ were calibrated in vitro with media of ionic composition similar to axoplasm containing CaEGTA buffers. Calcium loads of 50-2,500 mumol/kg axoplasm were induced by mi...

an important part of carbon cycling is carried out in the soil making land use changes, including changes in forestlands, affect soc storage and consequently co2 flux into the atmosphere.the aims followed in this investigation were to study the impacts of conversion of deciduous forests to coniferous ones and deforested land to rangelands, on some of the soil physicochemical properties, organic...

in order to evaluate yield and yield components properties of cold-tolerant chickpea under winter sowing and complementary irrigation conditions, two experiments in the context of partial balanced block design with 81 chickpea genotypes and three replications were carried out. complementary irrigation was performed during growing season including irrigation immediately after sowing, 20 days aft...
