We present new models for the formation of disk galaxies that improve upon previous models by following the detailed accretion and cooling of the baryonic mass, and by using realistic distributions of specific angular momentum. Under the assumption of detailed angular momentum conservation the disks that form have density distributions that are more centrally concentrated than an exponential. W...
Growing evidence indicate supermassive black holes (SMBHs) in a mass range of MBH∼ 10 6 − 10M⊙ lurking in central stellar bulges of galaxies. Extensive observations reveal fairly tight power laws of MBH versus the mean stellar velocity dispersion σ of the host stellar bulge. Together with evidence for correlations between MBH and other properties of host bulges, the dynamic evolution of a bulge...
The demand for more efficient manufacturing processes has been increasing in the last few years. The cold forging process is presented as a possible solution, because it allows the production of parts with a good surface finish and with good mechanical properties. Nevertheless, the cold forming sequence design is very empirical and it is based on the designer experience. The computational model...
We explore the relation between dust and several fundamental properties of simulated galaxies using Dusty SAGE semi-analytic model. In addition to tracing standard galaxy properties, also tracks cold mass in interstellar medium (ISM), hot halo ejected by feedback activity. Based on their ISM content, we divide our into two categories: dust-poor dust-rich. split group subgroups: dust-rich (the l...
cage roll forming is one of the new methods of cold roll forming process which is widely used for producing erw pipes. in addition to less production cost and time, using cage roll forming provides smooth deformation on the strip. few studies can be found about cage roll forming because of its complexity, and the available knowledge is more experience-based and not science-based. in this paper,...
Reinke's Space Oedema is characterized by a subepithelial collection of fluid and pseudo-myxomatous tissue within the lamina propria superficialis of the vocal cord. We have observed, in a number of cases, the phenomenon of bilobular and/or centrally located Reinke's Space Oedema. Bilobular oedema occurs when the sub-epithelial oedema is organised as a double bulge of the vocal cord in the supe...

A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...
