A bronze wine vessel attributed to 1600–1046 B.C., Shang dynasty in China, an object from the East Asian Collection of Museum Applied Arts and Sciences Sydney (Australia), was studied using a non-destructive scientific analytical protocol based on synergic combination nuclear techniques. Gamma spectrometry, neutron-computed tomography, proton-induced X-ray emission (PIXE) spectroscopy were appl...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

Genetic diversity in strawberry is low due to its asexual propagation. One method of increasing genetic diversity, as an important tool in plant breeding, is the use of gamma rays to induce mutation. In order to determine the appropriate dosage of gamma irradiation for genetic diversity creation by mutation in strawberry, Kurdistan cultivar, and to study the influence of various doses of gamma ...

There are two methods for identifying formation interface in oil wells: core analysis, which is a precise approach but costly and time consuming, and well logs analysis, which petrophysists perform, which is subjective and not completely reliable. In this paper, a novel coupled method was proposed to detect the formation interfaces using GR logs. Second approximation level (a2) of GR log gained...

background: knowledge of radioactivity levels in human diet is of particular concern for the estimation of possible radiological hazards to human health. however, very few surveys of radioactivity in food have been conducted in iran therefore the baseline values of the natural radionuclides concentration (40k, 226ra and 232th), and man made radionuclide, 137cs, were determined in twenty six sam...
