The technical principles and practices of the civil nuclear industry are described with particular reference to fission and its products, natural and artificial radioactivity elements principally concerned and their relationships, main types of reactor, safety issues, the fuel cycle, waste management, issues related to weapon proliferation, environmental considerations and possible future devel...
The knowledge of nuclear reaction rates is important for studying energy production and nucleosynthesis, especially in reactions including nuclei far from stability line, which are not accessible experimentally so far and thus it is necessary to be able to predict reaction cross sections in low excitation energies. Nuclear level density is one of the important key quantities in many nuclear phy...
Background: The nuclear medicine systems are very sensitive to the variation of the magnetic field. Photomultiplier tubes amplify low energy light signal and change it into electrical current. Low magnetic field can produce some variations in uniformity and special resolution of SPECT systems. In this study, we tried to evaluate the effects of magnetic field on the function of nuclear medic...
the storage capacity of hydrogen on na-decorated born nitride nanotubes (bnnts) is investigated by using density functional theory within quantum espresso and gaussian 09. the results obtained predict that a single na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) bnnt structures with a binding energy of -2.67 and -4.28 ev/na-atom respectively. when a si...
There are questions concerning the functions of artemin, an abundant stress protein found in Artemiaduring embryo development. It has been reported that artemin binds RNA at high temperatures in vitro, suggesting an RNA protective role. In this study, we investigated the possibility of the presence of RNA-bindingsites and their structural properties in artemin, using docking energy ...
Following the prediction by Akaishi and Yamazaki of relatively narrow K̄-nuclear states, deeply bound by over 100 MeV where the main decay channel K̄N → πΣ is closed, several experimental signals in stopped K reactions on light nuclei have been interpreted recently as due to such states. In this talk I review (i) the evidence from K-atom data for a deep K̄-nucleus potential, as attractive as V K̄ (...
in december 1953, the us president, general dwight d. eisenhower delivered his “atoms for peace” speech at the united nations' general assembly, which called for the promotion of peaceful uses of nuclear energy under special international agency. this proposal became the starting point for creating the iaea in 1957 and adopting npt in 1968. the atoms for peace initiative established the pr...
the 56th pugwash conference on science and world affairs opened with a key note address by the italian minister of foreign affairs, massimo d’alema, and the un secretary-general ban ki-moon’s message in bari, italy, on 21 october 2008. in the week-long meeting, the participants discussed a wide array of topics related to regional security issues such as the status of nuclear arms control, the r...
Zoanthamine-type alkaloids display a wide spectrum of biological effects. This study aimed to examine the inhibitory effects of norzoanthamine and its ten homologues of zoanthamine class on human fibroblast collagenase by modeling a three-dimensional structure of the ligands at collagenase using energy minimization, docking, molecular dynamics simulation and MM-PB/GBSA binding free energy calcu...
Background: Aromatase is an enzyme that plays an important role in the development of estrogen-positive breast cancer. Estrogens are essential in human and mainly in women because of their role in sexual development and reproduction. Adverse effects of some aromatase inhibitors increase the need to discover new inhibitors with higher selectivity, lower toxicity and improved potency. In this stu...
