The effects of the diameter and location an inserted wire on methane–air flame characteristics in a micro-burner, with backward-facing step, were investigated numerically. Our goal was to shed light parameters that authors had not already considered previous study. To do so, studied distribution temperature, H, OH species, scrutinized. It shown increasing wire’s relocating towards outlet polyno...

Advances in the additive manufacturing technology have led to the production of complex microstructures with unprecedented accuracy and due todesigning an effective implant is a major scientific challenge in bone tissue regeneration and bone growth. In this research, titanium alloy cylindrical scaffolds with three-dimensional architectures have been simulated and compared for curing partial bon...

In recent years, utilization of chitosan /tripolyphosphate nanoparticles has been considered greatly as protein delivery vehicles. Effects of a variety of factors on final characteristics of nanoparticles have been studied by many investigators. Although, the objective of this study was to achieve smaller chitosan nano carriers via changing fabrication parameters such as pH and temperature and ...

We investigate colors and mass-to-light ratios (M/Ls) of the bulges and disks for 28 nearby spiral galaxies with various morphological types of Sab to Scd, using images in optical and near-infrared (V , I, and J) bands and published rotation curves. It is shown that the observed colors and M/Ls generally agree with the galaxy formation model with an exponentially declining star formation rate a...

This paper demonstrates ETLMR, a novel dimensional Extract– Transform–Load (ETL) programming framework that uses MapReduce to achieve scalability. ETLMR has built-in native support of data warehouse (DW) specific constructs such as star schemas, snowflake schemas, and slowly changing dimensions (SCDs). This makes it possible to build MapReduce-based dimensional ETL flows very easily. The ETL pr...
