the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

New CO observations at the center of cooling flow in Perseus cluster [4] show a clear correlation of the molecular gas with the previously detected H-α filaments [1]. In this poster, we present high resolution multi-phase simulations of the Perseus Cluster, taking into account the AGN feedback in form of hot buoyant bubbles. These simulations show that significant amount of gas can cool far fro...

An elderly woman with a chronic decubitus sacral ulcer presented to the emergency department with sepsis. A computed tomography of her abdomen showed diffuse gas extending throughout the thoracolumbar spinal canal. Pneumorrhachis is a rare radiographic finding defined as gas within the spinal canal. There are many causes of pneumorrhachis ranging from trauma to infection. In this case the pneum...

The central kpc of barred galaxies exhibits a wealth of morphological information on different components with clear dynamical consequences. These include nuclear rings, spirals, bars, and more. We argue that this morphology is driven by large-scale stellar bars and analyze its consequences for gas dynamics and the distribution of star-forming regions. Specifically, we focus on gas flows in nes...

It has become increasingly apparent that Bacillus cereus can cause a severe and devastating form of endophthalmitis following penetrating trauma by a metallic object. B. cereus is an uncommon aetiological agent in non-clostridial gas-forming infections. The patient studied in this single case report showed evidence of intraocular gas mimicking gas gangrene infection. The physiology of non-clost...

We study the evolution of dwarf (LH < 10 9.6 LH⊙) star forming and quiescent galaxies in the Virgo cluster by comparing their UV to radio centimetric properties to the predictions of multizone chemospectrophotometric models of galaxy evolution especially tuned to take into account the perturbations induced by the interaction with the cluster intergalactic medium. Our models simulate one or mult...

Gas detonation forming is a high-speed forming method, which has the potential to form complex geometries, including sharp angles and undercuts, in a very short process time. Despite many efforts being made to develop detonation forming, many important aspects remain unclear and have not been studied experimentally, nor numerically in detail, e.g., the ability to produce sharp corners, the effe...

The main goal of this thesis is to investigate the physical conditions of the star-forming environment in stellar clusters, especially · for the formation of low-mass cluster members. Embedded, young, and intermediate~mass stellar . clusters around Herbig . Ae/Be stars are sampled. Midand near-infrared observations identifying young stars and millimeter I interferometric observations probing de...

We present a study of the connection of star-forming galaxies, AGN host galaxies, and normal earlytype galaxies in the Sloan Digital Sky Survey (SDSS). Using the SDSS DR5 and DR4plus data, we select our early-type galaxy sample in the color vs. color-gradient space, and classify the spectral types of the selected early-type galaxies into normal, star-forming, Seyfert and LINER classes, using se...
