abstract background: dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. the aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (mwa) patients with migraine without aura (mwo) ones. methods: ten mwa patients (7 females and 3 males mean age: 39.70 years, sd...

background and objectives : 300 pseudomonas aeruginosa strains were isolated from hospitalized patients in iran. using international antigenic typing system (iats) antibodies, all strains were classified into 16 serotypes while serotype 14 was not identified among the 17 known serotypes. to evaluate the rate of cross-reactivity between o- antigenic determinants, monospecific polyclonal antibodi...

The reactivity of a fuel assembly including burnable absorbers can become the largest at low burnup, so accuracy calculations for such systems is important. To investigate this issue, impact gadolinium isotopes’ nuclear data on neutron multiplication factor k quantified. Sensitivities to are calculated from 0 20 GWD/t BWR 3 × multicell model. Sensitivity gadolinium-157 (n,γ) cross section becom...

Current assimilation of integral experiments often consists in adjusting multi-group cross sections with feedbacks from critical reference benchmarks. In order to maintain the constraints coming nuclear models, we present here a method achieve experiment on parameters, which data are evaluated. This method, based Bayesian inference, uses continuous energy reactivity sensitivities throughout all...

The basis of the MOX (Mixed OXide) energy equivalence principle is keeping in-core fuel management characteristics (cycle length, feed size, etc.) a nuclear reactor unchanged when replacing UOX (Uranium assemblies by MOX. If effect loading pattern neglected, such an obtained tuning Pu content in fuel, while considering specific isotopic vector at time core reload to obtain crossing reactivity c...

The fusion reactions involving deuterium are of great interest for the exploitation energy via magnetic-confinement devices. In classical thermodynamics, spontaneity a process is established through assessment change in Gibbs free energy. So far, feasibility nuclear has been characterized terms cross section and Q-value while entropic term (T ΔS) neglected. Such an assumption always justified f...

A novel simulation to calculate the neutronic parameters of TRIGA 2000 reactor using plate-type fuel has been performed. The plate used was produced by Indonesian Nuclear Industry (PT INUKI) with U3Si2-Al material. Neutronic based on INUKI’s dimension and current TRIGA’s configuration were simulated MCNPX. performed modeling complete reactor’s a fresh core state. We obtained kinetic parameter v...

In India Co-60 is the isotope presently being used for medical applications. It needs frequent replacement because of its short half life (5.27 Years) resulting in multiple handling, transportation and loadingunloading operations. Further, in Indian scenario, production of Co-60 also leads to reactivity losses and in turn revenue losses to the nuclear power reactors. However, Cs-137, the major ...
