High-Throughput Identification and Screening of Novel Methylobacterium Species Using Whole-Cell MALDI-TOF/MS Analysis
(Public Library Science, 2012)Methylobacterium species are ubiquitous alpha-proteobacteria that reside in the phyllosphere and are fed by methanol that is emitted from plants. In this study, we applied whole-cell matrix-assisted laser desorption/ionization ... -
Electroacoustic measurements of mixed quartz and iron oxide mineral systems
(Elsevier Science Bv, 2012)Surface behavior of the commonly found minerals in nickel laterite ores - quartz, magnetite, hematite and goethite was investigated using electroacoustic measurements. The goal was to assess the surface potentials as single ... -
Microstructural investigation and the creep behavior of Mg-Sr-Mn alloys
(Elsevier Science Sa, 2012)The Mg-Sr-Mn ternary alloy system exhibits potential for good creep performance in powertrain applications. Consistent with thermodynamic calculations, the microstructure of as-cast (AC) alloys exhibit Mg17Sr2 and alpha-Mn ... -
Bessel collocation approach for solving continuous population models for single and interacting species
(Elsevier Science Inc, 2012)In this paper, we present a collocation method to obtain the approximate solutions of continuous population models for single and interacting species. By using the Bessel polynomials and collocation points, this method ... -
Effects of heat treatment and surface roughness on bonding strength
(Elsevier Sci Ltd, 2012)The objective of this study was to determine the effect of heat treatment on bonding strength of the samples from four different species, namely Scotch pine, oriental beech, white oak and Uludag fir woods. The samples were ... -
Application of Bismuth(III)-Entrapped XO Biosensing System for Xanthine Determination in Beverages
(Springer, 2012)A xanthine biosensor was prepared by electrochemical immobilization of xanthine oxidize enzyme onto carbon paste electrode via entrapment of Bi3+. After the optimization of experimental parameters, analytical characteristics ... -
