Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...

Background: Diabetes is a prevalent chronic disease around the world. To evaluate risk of diabetes comprehensively, we developed a score model for the risk prediction with HDL-C as a protective factor. Methods: We extracted physical examination data of 2728 individuals. The data contain 18 demographic and clinical variables. To identify the statistical significant feature variables, the backwa...

BACKGROUND Neuron specific enolase (NSE) has repeatedly been evaluated for neurological prognostication in patients after cardiac arrest. However, it is unclear whether current guidelines for NSE cutoff levels also apply to cardiac arrest patients treated with hypothermia. Thus, we investigated the prognostic significance of absolute NSE levels and NSE kinetics in cardiac arrest patients treate...

OBJECTIVE To define physiologic levels of reactive oxygen species in infertile men and establish a cutoff value of reactive oxygen species level in neat semen with a high sensitivity and specificity to differentiate infertile men from fertile donors (controls). DESIGN Reactive oxygen species levels were measured in the neat semen samples (n = 51) from fertile donors and infertile patients (n ...

Levels of alpha-fetoprotein (AFP), its glycoforms AFP-L3 and AFP-P4, and proteins induced by vitamin K absence or antagonist-II (PIVKA-II) were determined in sera obtained from patients in Yangon General Hospital (20 with hepatocellular carcinoma (HCC), 29 with chronic liver diseases, including 3 with chronic hepatitis and 26 with cirrhosis of the liver, and 9 with other hepatobiliary diseases)...

The present study descriptively compares the need for recovery (NFR) among 128 nursing professionals (nurses) and 223 call center operators according cutoff points in the literature (45 and 50) and by means of statistical tests, and verifies the association between NFR scores and the presence of musculoskeletal symptoms. NFR was evaluated with the Need for Recovery Scale and musculoskeletal sym...
