Various factors affect the degree of mass crime of an environment, including social, economic, and physical factors. The purpose of this research is to investigate the role of the physical components of an environment on mass crime rate. In this regard, open spaces between residential complexes were selected as the case studies and based on five outdoor patterns including linear pattern, disper...

Hypoallergenic antibacterial low-molecular-mass peptides were produced from defatted soybean meal in a membrane bioreactor. In the first step, soybean meal proteins were digested with trypsin in the bioreactor, operated in batch mode. For the tryptic digestion of soybean meal protein, optimum initial soybean meal concentration of 75 g/L, temperature of 40 °C and pH=9.0 were determined. After en...

in this work, we have calculated the joule-thomson inversion curve of two important associating fluids, namely water and methanol, from the saft equation of state. comparisons with the available experimental data, for water and methanol indicate that this molecular based equation of state gives good prediction of the low temperature branch; but, unfortunately, due to lack of isenthalpic data fo...

the quantitative structure-property relationship (qspr) method is used to develop the correlation between structures of refrigerants (198 compounds) and their critical temperature. molecular descriptors calculated from structure alone were used to represent molecular structures. a subset of the calculated descriptors selected using a genetic algorithm (ga) was used in the qspr model development...

We present results of experiments on mixtures of olivine tholeiite and mantle harzburgite, at 5 kb and 1050-1150°C, under conditions of controlled hydrogen fugacity. The basalt end-member was Kilauea 1921 olivine tholeiite + 3 wt.% H2O, and the harzburgite end-member was a mixture of olivine and orthopyroxene mineral separates made from a mantle-derived lherzolite xenolith. The experiments on m...

RESULTS AND DISCUSSION The combination ion source gave comparable performance in liquid SIMS mode to the standard Nermag FAB ion source (data not shown), indicating that the hemispherical repeller was an adequate substitute for the curved metal strip repeller on the standard FAB ion source. The results of sample analysis in electrospray mode are shown in Figurea 2-5. Figure 2 shows data obtaine...

The phenylalanine-inhibitable 3-deoxy-D-arabino-heptulosonate-7-phosphate (dHp1P) synthase from Saccharomyces cerevisiae has been purified to apparent homogeneity by a 1250-fold enrichment of the enzyme activity present in wild-type crude extracts, employing an overproducing strain. The estimated molecular mass of 42 kDa corresponds to the calculated molecular mass of 42.13 kDa deduced from the...

Purified native Tromp1 was subjected to mass spectrometric analysis in order to determine conclusively whether this protein possesses a cleaved or uncleaved signal peptide. The molecular masses of Tromp1, three Treponema pallidum lipoproteins, and a bovine serum albumin (BSA) control were determined by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. The...
