ABSTRACT We have determined stellar mass functions of 120 Milky Way globular clusters and massive Large Magellanic Cloud/Small Cloud star based on a comparison archival Hubble Space Telescope photometry with large grid direct N-body simulations. find strong correlation the global function slopes both their internal relaxation times lifetimes. Once dynamical effects are being accounted for, most...

This research investigates the stress mechanics of reinforced polyester composites when exposure to a sudden impact force, using experimental and analytical methods based on Linear Elastic Fracture Mechanics (LEFM) test procedures. In this study, distribution around crack tip zone for 14 samples with geometry 210 mm x 150 were investigated. KII intensity factors, critical stress, σC, shear τnt ...

A steady-state wedge-opening test has been developed in order to measure the work of separation of bonded silicon wafers. Non-steady-state and steady-state measurements are compared. Significant influence of i) the surface treatment, ii) the annealing time and temperature and iii) the crack velocity on the toughness is observed and related to the interface chemistry. A methodology based on the ...

prosite database contains a set of entries corresponding to protein families, which are used to identify the family of a protein from its sequence. although patterns and profiles are developed to be very selective, each may have false positive or negative hits. considering false positives as items that reduce the selectiveness of a pattern, then, the more selective pattern we have, a more accur...

We consider a natural covering responsible for the complexity of the ramification of roots of the general real polynomial equation, and calculate the homology groups of its base; for equations of degree ≤ 5 we give a complete description of the topology of this base. The general complex d-valued entire algebraic function x = F (a1, . . . , ad), given by the equation (1) x + a1x + · · ·+ ad−1x+ ...

recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. differed methods for protein purification are categorized, based on cast, quality, easy work and side effect of protein. in this article, we are investigating his his-tag protein pu...
