a new species of cassiduloid echinoids, pygaulus baghinensis is reported for the first time from aptian sediments of baghin area, west of kerman, iran. the diagnostic features of the species are centrally positioned of the apical disc and approximately low profile of the test. variation in gonopore size in different individuals allows to conclude that p. baghinensis is sexually dimorphic. speci...

In this study, an Eulerian-Eulerian multi-fluid model (MFM) was used to simulate the segregation pattern of a conical fluidized bed containing ternary mixtures of equidensity TiO2‌ particles. Experimental 'freeze–sieving' method was employed to determine the axial mass fraction profiles of the different-sized particles, and validate the simulation results. The profiles of mass fraction for larg...

Most people are aware that regular alcohol drinkers can become tolerant to the effects of alcohol. Tolerance can lessen the outward manifestations of intoxication, and this poses challenges for the drinker and other observers, including law enforcement officers. On the basis of a National Institutes of Health-funded longitudinal study examining a cohort of convicted alcohol-impaired drivers, th...

In my mind I'd just watch it go till it was just a speck , and then I'd think about the sweet sound it would make breaking to pieces on the river rocks way down below. from Cold Mountain, by Charles Frazier.1

For many years, the only way to attain an education in software engineering has been through the school of hard knocks. A common lament among experienced software developers is that colleges don’t teach students the skills they need to perform effectively on the job. What is needed to give software developers a better start? Formal professional education has traditionally been divided into thre...
