We consider clean cylindrical nanostructures with an applied longitudinal static magnetic field. Without Coulomb interaction, the field induces, for particular values, points of degeneracy where a change of ground state takes place due to Aharonov-Bohm effect. The Coulomb potential introduces interaction between the electronic configurations. As a consequence, when there is degeneracy, the grou...
In the current research, hydroxyapatite samples, synthesized by hydrothermal methods was studied from the perspective of thermoluminescence dosimetry. The results of the study were compared and studied with different aspects of dosimetry, including dose-response variations of synthesized samples, degree of its linearity, and the percentage of response fading, as well as the position of the main...
it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...
The dissociation energy of the ground state of NaH was determined by analyzing the observed near dissociation rovibrational levels. These levels were reached by stimulated emission pumping and fluorescence depletion spectroscopy. A total of 114 rovibrational levels in the ranges 9<or=v(")<or=21 and 1<or=J(")<or=14 were assigned to the X (1)Sigma(+) state of NaH. The highest vibrational level ob...
Background and Purpose: NO is a short-lived gas molecule generated by degradation of L-arg to citrulline and by the activation of enzyme NOS Ca2+/calmodulin-dependent. There are multiple NOS isoforms that strongly are expressed in skeletal muscle, suggesting the crucial role of NO in regulating muscular metabolism and function. In this study, the effect of L-arginine was examined at the neuromu...
Quantitative determination of most economic valuable metals in waste is the first fundamental operation evaluating feasibility recycling processes. Field-portable X-ray fluorescence spectrometers (FPXRFs) represent a more practical, efficient, and tool determining elemental composition samples with respect to conventional analytical techniques, such as atomic absorption spectrometry (AAS) induc...
teucrium polium l. (lamiaceae) is used in the traditional medicine of iran for the treatment of disorders of the gastrointestinal tract. the essential oil from the aerial parts of t polium was assessed for antispasmodic activity and compared with the effect of atropine and dicyclomine. acetylcholine and kc i were used for induction of contraction on rat isolated ileum. teucrium polium essential...
A rational parametrization of an algebraic curve establishes a rational correspondence of this curve with the affine or projective line. This correspondence is a birational equivalence if the parametrization is proper. So, intuitively speaking, a rational parametrization determines a linear tracing of the curve, when the parameter takes values in the algebraic closure of the ground field. Such ...
Background and aims: Exposure to the normal hexane can induce dysfunction of the nervous system and color vision impairment. Occupational risk assessment is established according to no observed adverse effect levels (NOAEL). Recently, because of the NOAEL’s limitations, the benchmark responses were applied for risk assessment. The study’s aim is an analysis of benchmark response in occupational...
