The effectiveness of choice theory group therapy of glasser on divorced women self-efficacy

The purpose of the present research was to study the effectiveness of choice theory group therapy by William Glasser (1998) on divorced women self-efficacy between 18 to 23 years old. The research was semi experimental type along with pretest-past test. Using self-efficacy questionnaire (SGSES), 30 women who was of low self-efficacy were chosen on simple random and were randomly divided into experimental and control groups. Experiment group received 8 sessions treatment of Choice Theory group therapy for two months while the control group did not receive any training. After receiving training, self-efficacy was measured for next time. The collected data was analyzed by SPSS v.21 and by applying multivariate analysis covariance. The results revealed self-efficacy (P<0.05) significant effect. The present investigation clarified choice theory group therapy increased divorced women self-efficacy

Effect of vacancy defect on natural vibrations of a single walled …

In this paper, the effect of vacancy defect on natural vibrations of single walled carbon nanotubes (SWCNTs) is investigated. Vacancy defect occurs during growth process therefore determining natural frequency of defected SWCNTs is very important for improving their sensing or actuating performance. Molecular dynamics and finite element methods have been employed to simulate SWCNTs. Related stiffness is calculated from molecular potential energy. Accuracy of modeling is determined by comparing our results of predicting ideal SWCNT natural frequency with the results from the previous studies. Two cases are studied. First, vacancies are scattered randomly on SWCNT structure for better simulation of actual condition, and effect of aspect ratio, vacancy ratio, and boundary conditions on natural vibration of defected SWCNTs is investigated. Second, single vacancy is considered and effect of aspect ratio, vacancy position and boundary conditions on natural vibration of defected SWCNTs is investigated. Zigzag carbon nanotubes with chirality indices (8, 0) and (10, 0) are studied in both cases. The results, in the first case, indicate that by increasing aspect ratio, the principal natural frequency shift decreases. This shift is affected by vacancy ratio. Distribution of vacancies affect natural frequency shift. As vacancies approach to the clamped end, natural frequency shift increases. In the second case, effect of aspect ratio, vacancy position, and boundary conditions is investigated

Hotspots and key periods of Greenland climate change during the past six decades

We investigated air temperature and pressure gradients and their trends for the period 1996–2014 in Greenland and compared these to other periods since 1958. Both latitudinal temperature and pressure gradients were strongest during winter. An overall temperature increase up to 0.15 °C year(−1) was observed for 1996–2014. The strongest warming happened during February at the West coast (up to 0.6 °C year(−1)), weaker but consistent and significant warming occurred during summer months (up to 0.3 °C year(−1)) both in West and East Greenland. Pressure trends on a monthly basis were mainly negative, but largely statistically non-significant. Compared with other time windows in the past six decades, the period 1996–2014 yielded an above-average warming trend. Northeast Greenland and the area around Zackenberg follow the general pattern but are on the lower boundary of observed significant trends in Greenland. We conclude that temperature-driven ecosystem changes as observed in Zackenberg may well be exceeded in other areas of Greenland

Adaptive Speech Enhancement Using Partial Differential Equations and Back Propagation Neural Networks

Abstract: In this work, we propose a new approach to improve the performance of speech enhancement technique based on partial differential equations. As we know, the real-world noise is highly random in nature. So we try for reduction of white Gaussian noise. The proposed method was evaluated on several speakers. The subjective and objective results show that the new method highly improves speech enhancement. Comparisons of several methods are reported

Vegetation phenology gradients along the west and east coasts of Greenland from 2001 to 2015

The objective of this paper is to characterize the spatiotemporal variations of vegetation phenology along latitudinal and altitudinal gradients in Greenland, and to examine local and regional climatic drivers. Time-series from the Moderate Resolution Imaging Spectroradiometer (MODIS) were analyzed to obtain various phenological metrics for the period 2001–2015. MODIS-derived land surface temperatures were corrected for the sampling biases caused by cloud cover. Results indicate significant differences between West and East Greenland, in terms of both observed phenology during the study period, as well as the climatic response. The date of the start of season (SOS) was significantly earlier (24 days), length of season longer (25 days), and time-integrated NDVI higher in West Greenland. The sea ice concentration during May was found to have a significant effect on the date of the SOS only in West Greenland, with the strongest linkage detected in mid-western parts of Greenland

Molecular investigation of extended-spectrum β-lactamases (ESBLs) genes in the Salmonella isolates obtained from children with acute diarrhea

Salmonellosis is an important public health concern among children in worldwide. Extended-spectrum β-lactams (ESBLs) cause resistance to clinically important beta-lactams which are generally used to treat invasive Salmonella infections. Therefore, the aim of this study was to investigate the presence of SHV, TEM and CTX-M genes in different strains of Salmonella isolated from children with acute diarrhea and to determine their resistance profile. In this cross-sectional study, 300 fecal samples were collected from children referred to the Amirkola Children's Hospital, Babol, Iran. Antibiotic susceptibility testing was done according to the CLSI guideline. ESBLs-producing strains were identified using double disk synergy test method on the Mueller-Hinton agar plates. Multiplex-PCR was performed using oligonucleotide specific primers to detect of SHV, TEM and CTX-M genes. In total, 7% (n; 21/300) salmonella were isolated, which 61.9%, 28.6% and 9.5% were Salmonella typhimurium, Salmonella enteritidis and Salmonella typhi, respectively. The prevalence of the ESBL-producing isolates were 52.4%. M-PCR results showed that 42.8%, 38.1% and 14.3% of isolates were carried CTX-M, TEM and SHV genes, respectively. Also, 18.2% of isolates harbored CTX-M, and TEM genes, simultaneously. The high rate of ESBLs-producing Salmonella strains in the pediatric patients is an alarm. It is also recommended that alternative drugs be used with less resistance, which requires further investigation

Outer Ear Infections in Iran: A Review

BACKGROUND: Otitis externa is the fungal and bacterial infection of the outer ear. AIM: We aimed to investigate the published papers about the outer ear infections in Iran and suggest standardised investigations and treatments. METHODS: We used different electronic databases like PubMed, Scopus, Web of Science, Iranmedex, Google Scholar, and Magiran with specific keywords. RESULTS: We obtained forty published full-text articles for review of data. Our results indicated the women were more infected than men. The ages of patients were &lt; 1-81 years. As clinically symptoms, itching and Feel the ear fairy were the most common presenting complaints in most cases. Most infections were the pure bacterial and fungal origin, respectively. However, some of the studies were mixed fungal-bacterial infections — Pseudomonas spp. And Aspergillus niger were the most common bacteria and fungi isolates respectively in Iranian patents. CONCLUSION: Fungal and bacterial specific cultures may be recommended, and anti-fungal drugs may be added, to treatment regimens in patients with otitis externa to reduce the clinical symptoms

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations
