Chemical mutagenesis of Staphylococcus aureus RN450 generated two strains that displayed a stable reduction (30- to 60-fold) in susceptibility to evernimicin. Cell-free translation reactions demonstrated that the resistance determinant was located in the ribosomal fraction. Compared to ribosomes isolated from a wild-type strain, ribosomes from the mutant strains displayed an 8- to 10-fold reduc...

The MCDM problem is very important and often encountered in life engineering as it used to determine the best solution among various possible alternatives. In this paper, results of dressing process for internal grinding are presented. To perform work, an experiment with six input parameters, including depth time fine dressing, coarse non-feeding feed rate, was conducted. designed according Tag...

Abstract Chemical treatment can effectively reduce the surface roughness of fused deposition modeling (FDM) parts. An effort is made in this study to appraise finish poly lactic acid (PLA) parts by FDM with hot vapor smoothing treatment. The tests were designed as per Taguchi L16 orthogonal array based factorial design experimentation while varying process parameters such time, temperature and ...

In this numerical and statistical study, lift drag coefficient performances of NACA-0009 NACA-4415 airfoils were evaluated in accordance with various attack angle at constant velocity wind. Lift coefficients was numerically determined by computational fluid dynamics code ANSYS FLUENT. Analysis design calculations implemented using L16 orthogonal array based on Taguchi method. Angles airfoil typ...

Solidity is one of the main factors that influence performance a wind turbine. The solidity an H-Darrieus turbine optimized in terms blade number, chord length, and rotor radius to get maximum power coefficient using Taguchi L16 (4^3) array. Power values are calculated by Double Multiple Stream Tube model house built MATLAB code according orthogonal found as 0.4728 for two-bladed with length 0....

Abstract Water pollution connected with rapid industrial growth is one of the most challenging issues worldwide. The disposal heavy metals turns out to be complex and expensive, so several researchers have tried remove these pollutants based on abundantly available, inexpensive materials, such as agsricultural waste used sorbents; however, materials not achieved sufficient removal rates. Conseq...

Sectoral Shifts, Diversification and Regional Unemployment: Evidence from Local Labour Systems in Italy Using Local Labour Systems (LLSs) data, this work aims at assessing the effects of sectoral shifts and industry specialization patterns on regional unemployment in Italy over the years 2004-2008, when huge worker reallocation caused by changes in the international division of labour occurred....

We analyze the relative growth performance of open economies in a two-country model where di¤erent endowments of labor and a natural resource generate asymmetric trade. A resource-rich economy trades resource-based intermediates for …nal manufacturing goods produced by a resource-poor economy. Productivity growth in both countries is driven by endogenous innovations. The e¤ects of a sudden incr...
