Friction Coefficient for Deep-Inelastic Heavy-Ion Collisions

Based on the microscopic model, the friction coefficient for the relative motion of nuclei in deep-inelastic heavy-ion collisions is calculated. The radial dependence of the friction coefficient is studied and the results are compared with those found by other methods. Based on this result, it was demonstrated that the kinetic energy dissipation in deep-inelastic heavy-ion collisions is a gradual process which takes up a significant part of a reaction time. An advantage of the suggested method is that it allows one to consider the relative motion of nuclei and the intrinsic motion self-consistently.Comment: 15 pages, RevTex, 7 Postscript figures, submitted to Phys.

Machining millimeter-scale deep holes in SiCf/SiC material using femtosecond laser filamentation effect

A 3.5 mm thick SiCf/SiC material was drilled in air environment using a femtosecond laser filament effect. The surface morphology of deep micropores was observed by scanning electron microscopy and the depth and profile of the pores were observed using μm-CT. The variation of entrance diameter, exit diameter and depth variation with laser focus position and processing time was further analyzed. The results showed that as the processing time of femtosecond laser increases, the ablation threshold of the material reached saturation. The exit and entrance diameter also stopped increasing and the aperture tend to saturate. The focus entered the interior of the material, allowing the location of the peak power near the surface of the material. So the entrance aperture was of good quality and the exit aperture was round

A Study of Life Skill Components in Clients Referred to Health and Counseling Centers

Background: Life skills include a set of abilities to increase the power of adaptability and positive behavior. The objective of this study was to determine the distribution of ten life skill components and their related factors among individuals referring to veterans' health and counseling centers in the city of Tehran. Methods: A cross-sectional study was conducted among participants over the age of 20. The sample size was estimated based on the Morgan table and Cochran sampling formula. The present study utilized the shortened life skills scale including 10 subscales.  Data were analyzed using statistical t-test, Pearson correlation, and one-way analysis of variance. Results: The total mean of life skills was significantly higher among women (P value=0.01). Age had a significant direct correlation with total life skills (r=0.19). There were significant differences between the three educational levels in 8 out of 10 components. The decision-making power had a significant correlation with "problem solving" and "creative thinking". "Critical thinking" had a high correlation with "effective communication", "coping with stress" and "attracting social support". "Coping with emotion" had a direct and high correlation with "coping with stress" and "self-awareness" but its correlation was reversed with "creative thinking". Conclusions: The mean score of life skills among clients of veteran`s health and counseling centers was slightly higher than the average population; while the rate of enjoyment of life skills was different in this subpopulation. The results implicate an urgent need to improve life skills, especially for highly educated people. Keywords:  Life skills, Veterans, Cross-sectional study, Iran

Influence of Aerobic Training and Selected Asanas Modulates Serum Lipds and Lipoproteins in Young Obese Males

Abstract The aim of the study was to analyze the effect of aerobic training and selected asanas on serum lipids and lipoproteins in young obese men.  To achieve the purpose, sixty obese male students were selected randomly from different faculties of Annamalai University, and their age ranges between 18 to 25 years. Selected subjects were classified into three groups with twenty members of each. Group 1 served as control, Group 2 act as aerobic training and Group 3 as asanas training group. Exercise training such as aerobic exercise and selected asanas were given to the experimental training groups for a period of three months (4 days/ week) whereas the control group was given no special training other than regular activities.  Blood samples were collected before and after the completion of full training course. Biochemical analyses were done on serum lipids (total cholesterol, triglycerides, free fatty acids and total phospholipids) and plasma lipoproteins (VLDL, LDL and HDL) to find out the significant effect of training on obese men. The data were collected and statistically analyzed using ANOVA and DMRT and they are significant at

The grain production potential assessment with multiple cropping index (MCI) in China

This paper retrieved the information of cropland and MCI (Multiple Cropping Index) of China in 2000 and 2009 with SPOT NDVI time series data and utilized meteorological data and statistical data released by the state to calculate potential MCI and statistical MCI. Then, the MCI potential of China and grain production potential based on MCI were calculated in order to analyze the potential spatial distribution characteristics of MCI and the potential spatial pattern characteristics. The national mean MCI potentials in 2000 and 2009 are 0.485 and 0.506 respectively calculated with the remote sensing method and statistical method. And the grain productivity potentials of China based on MCI are 51% and 53% respectively. The improvement of MCI potential not only increases hydrothermal utilization rate and the utilization rate of cropland but also enormously enhances the food security degree of China and provides more available cropland area for the economic development

The Role of Professional Behavior to Improve Patient Safety Culture in Clinical Nurses: A Cross-Sectional Study

Background: Safety culture is one of the most important determinants of patient safety in hospitals. Due to the increasing prevalence of medical errors, increasing public attention, and public opinion pressure on this issue as well as the limitations of studies in this area, the current study was conducted to identify the role of professional behavior to improve patient safety culture in clinical nurses. Methods: This cross-sectional study was performed on 230 nurses in Shahroud Iran. Data collection instruments included a demographic information form, the Hospital Survey on Patient Safety Culture questionnaire, and the Nursing Professional Behaviors Scale. Stratified random sampling was used and data were analyzed by using descriptive and inferential statistics (linear regression analysis). Results: Participants’ mean scores of patient safety culture and professional behavior were 132.51 ±15.97 and 109.57±18.01, respectively. A high score of nurses' professional behavior was directly associated with a higher level of patient safety culture. In addition, the number of working hours per week and change in the workplace were significantly related to patient safety culture level (Pvalue=0.002). Conclusions: Professional behavior is an effective factor in enhancing safety culture in nurses. Therefore, paying attention to the training and proper application of professional behavior in nurses can improve the level of patient safety culture.

BIOANALYTICAL METHOD DEVELOPMENT AND VALIDATION OF NIRAPARIB IN PLASMA SAMPLES BY LC-MS/MS

In this manuscript, authors developed a simple, sensitive and specific liquid chromatography–tandem mass spectrometry (LC–MS/MS) method was used for quantification of Niraparib in plasma samples. Zorbax SB-C18, 4.6 x 75 mm, 3.5 μm, 80 Å column, 5mM ammonium acetate: methanol (30:70 v/v) mobile phase was used for Chromatographic separation of Niraparib. MRM positive mode was used to detect the Niraparib at 321.5195.4. Liquid-liquid extraction was employed in the extraction of analytes from human plasma. This method is validated over a linear concentration range of 10.0 – 10000.0 pg/mL with a correlation coefficient (r) of ≥ 0.9997. The developed method was validated and found to be table in plasma samples
