Electrochemical experiments have been carried out in order to identify traces of nuclear processes occurring in condensed matter. The experimental activity was primarily designed to reduce the background element impurities by using ultra-pure cleaning procedures to eliminate contamination. The working conditions allowed to obtain a clear signal from the investigated phenomena. Neutron activatio...

A wide range of minerals occurs in feedstuffs as naturally occurring and purposely added elements, as well as by adventitious contamination. These mineral elements can generally be classified as nutritionally essential major elements, nutritionally essential minor and trace elements, and those regarded as toxic or with an essential/toxic duality. A survey is presented of methods used for the de...

I consider a model of GRBs where they arise right before the merging of binary pulsars. Binary pulsars moving through the companion’s magnetic field experience a large, motional electric field ~ E = ~v ∧ ~ B/c, which leads to the release in the pulsar magnetosphere of a pair cascade, and the acceleration of a wind of pure pairs. The energy and energy deposition rate of the wind are those of γ–r...

Organohalogens, especially organochlorinated compounds (OCs) such as polychlorinated biphenyls (PCBs), have long been recognized as a potential threat to human health and, therefore, these compounds have been widely investigated in foods [3, 27], vegetation [9, 14], and the atmosphere [1, 11]. Recently, interest in using extractable organohalogens (EOX) as parameters for the quantification of t...

Heavy metals concentrations in water and sediment samples collected from five streams in Tarkwa gold mining district of Ghana were studied. The water and sediment samples were analysed for As, Al, Cd, Co, Cu, Hg, Mn, Sb, Th, and V, using Instrumental Neutron Activation Analysis (INAA). The results of this study generally showed elevated levels of all the ten examined elements in the water and s...

background; foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. the aim of this study was to evaluate the quality of some foods with high consumption in zanjan city during the 5 years from 2009 to 2013. methods; in a case-control descriptive study with an annually control program during 5 years fr...

The ARIES-RS tokamak power plant study developed a design approach which has the potential for high availability. One of the keys for high plant availability is a design that allows rapid replacement of the power core sectors. This is achieved by using large maintenance ports for each power core sector, enabling the removal of entire sectors composed of inboard and outboard blankets, neutron sh...

Study of nucleosynthesis in accretion disks around black holes was initiated by Chakrabarti et al. (1987). In the present work we do the similar analysis using the state-of-the-art disk model, namely, Advective Accretion Disks. During the infall, matter temperature and density are generally increased which are first computed. These quantities are used to obtain local changes in composition, amo...

A procedure for the simultaneous determination of arsenic, manganese, and selenium in human serum is described, and its performance characteristics are evaluated with particular reference to manganese. Blank values depend critically on irradiation containers, and only one type of polyethylene ampoule gave a sufficiently low limit of detection. Other suspected sources of random and systematic er...
