The effects of back pressure and cavity L/D ratio on the shock wave structure in the cold flow field of a typical cavity-based scramjet combustor with combined inlet and isolator is investigated numerically in the selected scramjet models. The scramjet with a throat ratio of TR 0.0 and cavity L/D 6.04 was analyzed. To perform such analysis, steady, 2-D RANS was used with SST k-ω. From the analysis, the value of static pressure along the cowl surface, contours of Mach number and pressure were obtained. The scramjet was modeled with different TR 0.1, 0.2, 0.25 and 0.3 with the same cavity L/D 6.04 and different cavity L/D 4.04, 9.04 and 12.04 with the same TR 0.25. All the models were analyzed with the same inlet conditions and the results were obtained. From the analysis, it was observed that the increase in back pressure moves the shock train towards the inlet of the isolator which leads to 'engine unstart' after the throat ratio of TR 0.1. Also, it is observed that there is an optimal L/D ratio of the cavity L/D 9.04 which restricts the propagation of high-pressure waves obtained in the combustor. [ABSTRACT FROM AUTHOR]

Docking is a term used for computational plans that undertaking to observe the best associating between two particles: a receptor and a ligand. Atomic docking is perhaps the most tremendous piece of the time included strategies in structure-based medicine game plan, by temperance of its ability to expect the keeping assortment of little molecule ligands to the genuine objective limiting site. Nuclear docking is the cycle that put particles for appropriate plans to connect with a receptor. Sub-nuclear docking is a brand name cycle which occurs inside the space of seconds in a cell. Depiction of the restricting behavior expects an essential part in sensible game-plan of meds correspondingly as to explain head biochemical cycles. Calcium oxalate monohydrate is the essential constituent of most of renal stones. Osteopontin, an aspartic corrosive rich urinary protein, and citrate, a lot more modest atom, are intense inhibitors of calcium oxalate monohydrate crystallization at levels present in typical pee. Present thoughts of the gig of site-express coordinated efforts in crystallization got from examinations of biomineralization are surveyed to give a setting to understanding guideline of COM improvement at a nuclear level. In this paper, the nuclear docking of In vitro calcium oxalate monohydrate tests with their cooperation are discussed and separated. [ABSTRACT FROM AUTHOR]

Textiles are considered to be an integral part of human life, since they are associated with the human body round the clock. Because of the various application of textiles in several fields, it is obvious that, people will expect functional characteristics such as comfort, healthcare, hygiene properties in clothing. The healthcare characteristics were also much expected in clothing to protect the human being from the adverse effects of outside environment resulting in infections and various diseases. The bacterial and viral infection is a common phenomenon in human's life causing much number of diseases from fever to major malfunctioning of important body parts. Hence this research work is focused specifically on identifying new approaches with the aid of technological advancements. This work aims at investigating the above-mentioned characteristics through developing natural based treatments such as charcoal applications with a specific focus on hygiene properties as their effects. The charcoal treated fabrics were also subjected to hygiene tests such as antibacterial and UV protection (UV Protection Factor, UPF) and have been found that the treated fabrics have developed antibacterial and UV protection properties.
