Small angle neutron scattering (SANS) measurements on Pd samples containing dislocations with a density of a few 10 cm 2 reveal an additional intensity for a scattering vector of 0.02 Å 1 to 0.2 Å 1 after loading with hydrogen (H) or deuterium (D). The corresponding net cross section is inversely proportional to the scattering vector as expected for line type scattering objects with a superimpo...

Using a combination of scanning electron microscopy, transmission electron microscopy (TEM), X-ray diffraction and X-ray photoelectron spectroscopy (XPS), we made a comparative study of the high-temperature annealing impact on thin titanium deuteride (TiD(y)) films covered by an ultrathin Pd layer, and on Ti/Pd bilayer films. The bilayer films were prepared under ultrahigh vacuum conditions and...

Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...

The transport properties of palladium hydride/deuteride are investigated using state-of-the-art density functional computational tools. This aspect of loaded hydride is important in that the resistance-loading curve is often used as a diagnostic in experiments to estimate the loading ratio. Understanding transport provides other important insights into some features of the nuclear reaction mech...

Background: This study investigated the effects of estradiol on plasma calcium and prolactin cells of Heteropneustes fossilis kept in calcium-deficient and normal freshwater. Methods: Fish were deprived of food and divided into groups A-D. Group A and B were kept in artificial freshwater with normal electrolytes. Group C and D were maintained in calcium-deficient freshwater. Vehicle was admin...

studies show that there is a substantial gap between the recommended daily calcium intake and what people actually consume. calcium food fortification is an effective method to increase daily calcium consumption. in the present study, the influence of three calcium salts at different levels was evaluated on physicochemical properties of set yoghourt such as ph, acidity, incubation time and syne...

background:   objective: in this study, we supplemented a chemically defined medium with different combinations of selenium, calcium and calcium ionophore concentrations to obtain the best rate of human oocytes maturation, survival, and fertilization.   materials and methods: as an experimental study, three combinations of [selenium (5 μg/ml), calcium (5 μg/ml) and calcium ionophore (1 μg/ml)],...

introduction: some studies in dental literature have proposed that short term and long term exposure of root dentin to calcium hydroxide predisposes it to fracture. mineral trioxide aggregate (mta) and a recently introduced endodontic material, calcium-enriched mixture (cem) cement may be used instead of calcium hydroxide and might have an effect on the strength of root dentin. therefore, the a...

Calcium deficiency causes Endocarp Lesion disorder in pistachio nut. To investigate the effects of various calcium treatments on Endocarp Lesion disorder and some nut qualitative characteristics in Pistachio cv. Akbari, an experiment was done in completely randomized design with four treatments (1- control treatment, 2- calcium chelate foliar spray, 3- calcium nitrate and 4– calcium sulfate (gy...
