{4,4'-Dimethyl-2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylylidene)]diphenolato}copper(II) monohydrate.

The asymmetric unit of the title compound, [Cu(C21H24N2O2)]·H2O, comprises half of a Schiff base complex and half of a water mol­ecule. The whole compound is generated by crystallographic twofold rotation symmetry. The geometry around the CuII atom, located on a twofold axis, is distorted square-planar, which is supported by the N2O2 donor atoms of the coordinating Schiff base ligand. The dihedral angle between the symmetry-related benzene rings is 47.5 (4)°. In the crystal, the water mol­ecule that is hydrogen bonded to the coordinated O atoms links the mol­ecules via O—H⋯O inter­actions into chains parallel to [001]. The crystal structure is further stabilized by C—H⋯π inter­actions, and by π–π inter­actions involving inversion-related chelate rings [centroid–centroid distance = 3.480 (4) Å]

Electric Switching of the Charge-Density-Wave and Normal Metallic Phases in Tantalum Disulfide Thin-Film Devices

We report on switching among three charge-density-wave phases - commensurate, nearly commensurate, incommensurate - and the high-temperature normal metallic phase in thin-film 1T-TaS2 devices induced by application of an in-plane electric field. The electric switching among all phases has been achieved over a wide temperature range, from 77 K to 400 K. The low-frequency electronic noise spectroscopy has been used as an effective tool for monitoring the transitions, particularly the switching from the incommensurate charge-density-wave phase to the normal metal phase. The noise spectral density exhibits sharp increases at the phase transition points, which correspond to the step-like changes in resistivity. Assignment of the phases is consistent with low-field resistivity measurements over the temperature range from 77 K to 600 K. Analysis of the experimental data and calculations of heat dissipation suggest that Joule heating plays a dominant role in the electric-field induced transitions in the tested 1T-TaS2 devices on Si/SiO2 substrates. The possibility of electrical switching among four different phases of 1T-TaS2 is a promising step toward nanoscale device applications. The results also demonstrate the potential of noise spectroscopy for investigating and identifying phase transitions in materials.Comment: 32 pages, 7 figure

Exploring Jahrom Medical University students' attitudes towards the Islamic self-evaluation in 2015

Introduction: Self- evaluation is the process of designing, building and maintaining human behaviors that can lead to maturity and perfection. Therefore, the aim of this study is to examine Jahrom Medical University students' attitudes towards the Islamic self-assessment in 2015.Method: This cross-sectional and descriptive study was carried out on the students of Jahrom University of Medical Sciences in 2015. Using purposive sampling, 223 samples were selected.Collection tool was Islamic self-assessment questionnaire in the form of 20 items based on the Likert scale consisting stipulation, calculating, meditation and expostulation. Data analysis was performed using statistical software SPSS 11 and paired T-test, ANOVA, Pearson correlation.Results: 223 students participated in this cross-sectional and descriptive study.68.2% were female and the rest were male. Their average age was 2.18 ± 20.4 in the range of 15 to 45 years.28.7 percent of students were medical field and 27.8 percent from the field of Anesthesiology.71.3% were undergraduates. The results of Pearson correlation coefficient showed that there was a significant correlation between the components of Islamic selfevaluation (stipulation, calculating, meditation, expostulation) and Islamic self-evaluation (P-value <0.05).Conclusion: The students of Jahrom University of Medical Sciences are in relatively good condition in terms of the four stages of Islamic self-evaluation.Keywords: Islamic self-evaluation, students, Jahrom University of Medical Science

The knowledge and the use of psychological skills of anger management skills at the bedside by the physicians and nurses of Jahrom University of Medical Sciences in 2013

Although all individuals could be exposed to the outburst of anger, a group of them are more at risk than others because of the nature of their work and responsibilities, that the physicians and nurses are placed in this group. In the field of psychology, different skills such as social protection systems, problem-solving skills, self-relaxation system, use of humor skills and communication and negotiation skills have been proposed to control anger. Given the importance of anger management in the prevention of job violence in the health environment and its impact on psychological health of psychiatrists and nurses and also the lack of information and research on the topic, this study aimed to study the knowledge and the use of psychological skills of anger management at the bedside by the physicians and nurses of Jahrom University of Medical Sciences.Methodology: This study is a cross-sectional and descriptive research, its studied sample included 259 general practitioners, specialists and nurses working in two general hospitals affiliated to Jahrom University of Medical Sciences. They were included in the study by the census method. The data was collected by the self-report method and two researcher-made questionnaires: a questionnaire of the knowledge of the psychological skills of anger management and a questionnaire of the use of anger management skills at the bedside and their validity (face and content) and reliability were examined before performing the research. Data analysis was performed with descriptive statistics (mean, frequency, percentage) using SPSS software.Results: The mean of the knowledge of the physicians and nurses of Jahrom University of Medical Sciences from the psychological skills of anger management was 30.2 (standard deviation is equal to 1.53) that based on the classification of the scores of related questionnaire, it was at a good level. Also, the results showed that the mean of the use of psychological skills of anger management at the bedside by the physicians and nurses working in Jahrom University of Medical Sciences was 39.54 (standard deviation is equal to 1.28) that based on the classification of the scores of related questionnaire, it was at a good level.Conclusion: According to the results, the knowledge and the use of psychological skills of anger management skills at the bedside by the physicians and nurses of Jahrom University of Medical Sciences were at the desired level, however, it is proposed to use other evaluation and assessment methods which have no limitations of self-report method in future studies.Keywords: anger management skill, nurses, physician
