numerous empirical correlations exist for the estimation of crude oil viscosities. most of these correlations are not based on the experimental and field data from iranian geological zone. in this study several well-known empirical correlations including beal, beggs, glasso, labedi, schmidt, alikhan and naseri were optimized and refitted with the iranian oil field data. the results showed that ...

Background The expression of CD64 in neutrophils (nCD64) has shown utility in the diagnosis of sepsis. The aim of this study was to evaluate the diagnostic value of neutrophil CD64 in pneumonia as an early marker for infection and correlate its level with the outcome of...

Background: The high workload of nurses in hospitals has been identified as a patient safety and worker stress problem. Psychological empowerment is a motivational concept demonstrated in four dimensions: meaning, competence, self-determination, and impact. Objective: This study investigated the relationship between nurses’ workloads and psychological emp...

We describe an attempt to numerically model Bose-Einstein correlations (BEC) from ”within”, i.e., by using them as the most fundamental ingredient of a Monte Carlo event generator (MC) rather than considering them as a kind of (more or less important, depending on the actual situation) ”afterburner”, which inevitably changes the original physical content of the MC code used to model multipartic...
