Normally, intensity patterns of vortex beams are closed rings such as Laguerre–Gaussian and Bessel–Gaussian beams. Recent studies showed that the with open ring structures, namely, (OVBs), have non-trivial orbital angular momentum (OAM) spectra optical forces can be employed in many applications metrology quantum information. However, structural stability OVBs, including topological charge cons...

interaction of drugs with serum albumin, the most abundant protein in plasma, has a great significance in pharmaceutical sciences. it can affect the biological activity, toxicity, and pharmacokinetics of drugs and design of dosages. determination of the impact of chemical modifications of albumin and its structural changes upon interaction with drugs are very important when drugs bind with albu...

The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies ...

the aim of this research was to evaluate some soil physical quality indicators using remotely sensed date, gis and geostatistical methods in baft area that is one of the most important centers of agricultural production in kerman province. therefore, soil samples were collected from 0 to 20cm depth of 183 points based on regular sampling pattern (every 250 meters) and soil physical indicators i...

Abstract:  In this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. For this purpose, the tangent plane distance (TPD) minimization method was used. First, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. The results show that for a binary mixture of th...
