ISOTHERMAL ENTHALPY AND DENSITY STUDIES OF POLYMERIC GLASSES VERSUS FORMATION PARAMETERS

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Thermodynamics of Enthalpy Relaxation and Hole Formation of Polymer Glasses

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Polymeric brushes with density dependent excluded volume parameters

Based on the recognition made by de Gennes that the excluded volume parameter of poly-ethylene-oxide (PEO) might depend on the local monomer density, we study the structure of PEO brushes in the limit where a local minimum is
