The purpose of this study was to develop and validate a scale of perceptions of well-being in key areas of life. We developed the I COPPE Scale, which incorporates overall as well as Interpersonal, Community, Occupational, Physical, Psychological, and Economic well-being. A total of 426 U.S. participants provided online responses to the I COPPE Scale and relevant comparison instruments. We used...

in this study, artificial neural network was used to predict the surface tension of 20 hydrocarbon mixtures. experimental data was divided into two parts (70% for training and 30% for testing). optimal configuration of the network was obtained with minimization of prediction error on testing data. the accuracy of our proposed model was compared with four well-known empirical equations. the arti...

biophysical profile (bpp) test is the most commonly used antenatal test of fetal well-being. purpose of this study is determining the influence of acoustic stimulation (as) on bpp testing time. about 55 pregnant women at 35 to 42 weeks who referred to department of obstetric & gynecology at university of medical sciences, tabriz, iran, were selected randomly. we used abdominal ultrasound guidan...

Although the multiplication of bacteriophages (phages) has a substantial impact on the biosphere, comparatively little is known about how the external environment affects phage production. Here we report that sub-lethal concentrations of certain antibiotics can substantially stimulate the host bacterial cell’s production of some virulent phage. For example, a low dosage of cefotaxime, a cephalo...

In recent years, the number of completions tight oil horizontal wells in field X has increased year by year. Horizontal well fracturing technology been widely used development reservoirs X. However, there are still some technical difficulties dynamic monitoring wells. Monitoring is mainly for inclined vertical wells, and few methods means Therefore, production each cluster after not accurately ...
