This new method which is worked out in Isfahan University of Technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by X Ray Diffraction and without any reference material. To identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. Amorphous phases should not exist. Intensity ratios ...

Digging of geotechnical boreholes and soil resistance tests are time-consuming and expensive activities. Therefore selection of optimum number and suitable location of boreholes can reduce cost of their drilling and soil resistance tests. In this research, a model which is consisting of geo statistics model as an estimator and an optimized model is selected. The kriging calculates the variance ...

ntimicrobianas empíricas en infecciones producidas por este atógeno. No podemos obviar la posibilidad de colonización de reserorios, pero tampoco podemos descartar la implicación de este icroorganismo en bacteriemias descritas5, dado que algunos atógenos desencadenantes de sepsis, pueden colonizar reservoios cutáneos (port-a-cath) y generar biofilms. Concluimos, que la secuenciación para la ide...

A study of the microstructure of polymers is essential for the understanding of their anomalous diffusion properties. The concept of free volume may be utilized to study relaxation phenomena and diffusion processes in polymers. Since a quantitative definition of free volume is not possible, a new concept called available volume is introduced. A simple geometric definition of available volume, r...

S e presentan dos métodos que se pueden utilizar como alternativas al GWAS para localizar QTLs en ganado. El primero se centra en el análisis de secuencias de homocigosis (runs of homozygosity, ROH) en grupos de animales (p.ej. casos y controles); el segundo es un método de remuestreo basado en la frecuencia de inclusión de los SNP en modelos predictivos. Las ROH se aplicaron a la identificació...

Over the past few years considerable research attention has been assigned to extremophiles as sources of extremozymes due to their applicability in industrial processes, and the development of eco-friendly technologies. The establishment of efficient production strategies for heterologous proteins is an empirical process requiring broad background knowledge on available expression systems toget...
