Small changes in temperature or pressure can lead to crude oil phase separation and multiple orders of magnitude change viscosity. The one-parameter friction theory framework using the SARA-based method with perturbed-chain statistical association fluid (PC-SAFT) EoS has proven have high accuracy viscosity predictions light oil. However, it failed for heavy In this work, above model is modified...

current research attempted to compare the effect of 10-day oral supplementation with saffron and indomethacin in the prevention of delayed onset muscle soreness (doms). thirty-nine healthy and inactive male students divided into three groups: saffron (300 mg), indomethacin (75 mg), and control groups. muscle soreness protocol performed with 80% of 1rm in four sessions and each session had 20 re...

A petroleum fluid can be di®ided into three types of species: asphaltenes, resins, and oils. Asphaltenes and resins are polar, while the rest of the so-called oils are either nonpolar or mildly polar. The interaction among these species strongly affect asphaltene precipitation from petroleum fluids. Different measuring methods for asphaltenes in a petroleum fluid gi®e similar results, but diffe...

The Raton Basin of Southern Colorado and Northern New Mexico experienced a significant increase in seismicity over the last several decades, including two M5+ earthquakes. started soon after an wastewater disposal associated with coal-bed methane production. Twenty-nine injection wells have operated Basin, high-rate injectors located within kilometer most seismically active regions. We develope...
