PURPOSE Angiotensin converting enzyme inhibitors (ACEI) and type I angiotensin receptor blockers (ARB) have been shown to exert significant effects on bone tissue via a local renin-angiotensin-aldosterone system (RAS). The aim of our study was to delineate their influences on fracture healing process. METHODS Sixty adult male Wistar Albino rats were(More)
Thymoquinone (TQ) is the active ingredient of Nigella sativa which has a therapeutic potential in cancer therapy and prevention. In this study, TQ has been shown to induce specific cytotoxicity and apoptosis and to inhibit wound healing in triple-negative breast cancer cell line. TQ also inhibited cancer growth in a mouse tumor model. Moreover, TQ and(More)
The results of a series of numerical simulations for the NASA low-speed centrifugal compressor are presented. Large-eddy simulation (LES) is carried out together with the most commonly used Reynoldsaveraged Navier–Stokes (RANS) models, including the mixing length, k– and k– models. Predictions are compared with the available experimental data. It is seen(More)
The influence of the initial finite stretching or compressing of the strip containing a single crack on the Energy Release Rate (ERR) and on the SIF of mode II at the crack tips is studied by the use of the Three-Dimensional Linearized Theory of Elasticity. In the present paper these investigations are developed for a strip made from composite material. It(More)
Noise radiation is of importance for the performance of centrifugal pumps. Aiming at exploring noise radiation patterns of a typical centrifugal pump at different flow rates, a three-dimensional unsteady hydro/aero acoustic model with large eddy simulation (LES) closure is developed. Specifically, the Ffowcs Williams-Hawkings model (FW-H) is employed to(More)
This study was carried out in Arsin (Trabzon/Turkey) in 2011. The effects of different harvest time and altitudes on the quality of the nuts have been investigated. The study was performed on Foşa hazelnut and the harvest process has been conducted at three terms, which are on normal harvest time and ten days before and after harvest time. The harvested(More)
− The traceability of the vibration measurements to SI units is maintained through the calibration of the reference transducers. Primary calibration of the reference transducers in the field of mechanical vibration and shock is performed in accordance with the international standard ISO 16063-11 [1]. In some applications beside magnitude of the transducer’s(More)
