ABSTRACT
Introduction: Work shifts have many physiological and psychological consequences and can lead to a number of consequences for nurses. The present study carried out with the aim of comparison of psychological components of quality of life associated with health in nurses in fix and variable shifts
Method: This was a comparative-cross sectional study. Participants in this study consisted of all nurses in Tabriz hospitals who were selected randomly and the sample size for each group were estimated as 80 participants. We used two demographic and psychological questionnaires
Results: Collected data were analyzed through descriptive statistical methods, mean and standard deviation and inferential statistical methods. There are significant differences in mental health and the component of role playing limitation due to emotional, and Happiness [P<0.01]; but there are not significant differences between two groups in social function [P>0.05]
Conclusion: Nurses with fixed work shifts reported better degrees of quality of life compared with nurses who work variable shifts
ABSTRACT
A chelating resin is prepared by condensation polymerization of aniline with formaldehyde and characterized by Fourier transform infrared spectrometer, elemental analysis and thermogravimetric analysis and studied for the preconcentration and determination of trace Molybdate ion from environmental water sample using inductive couple plasma atomic emission spectroscopy. The optimum pH value for sorption of the metal ion was 5. The sorption capacity of functionalized resin is 3.1 mg/g. The chelating sorbent can be reused for 20 cycles of sorption-desorption without any significant change in sorption capacity. The best desorption of the metal ions from resin was obtained by 0.5 mol/L nitric acid as eluting agent. The profile of molybdenum uptake on this sorbent reflects good accessibility of the chelating sites in the aniline- formaldehyde. Scatchard analysis revealed that the homogeneous binding sites were formed in the polymers. The equilibrium adsorption data of Molybdate ion modified resin were analyzed by five isotherm models such as Langmuir, Freundlich and Temkin. Langmuir isotherm parameters obtained from the four Langmuir linear equations by using linear method. Based on the Langmuir isotherm analysis, the monolayer adsorption capacity was determined to be 4.03 mg/g at 20 °C. The method was applied for molybdenum ions determination from river water sample

Introduction: infertility and depression are major problems of today's societies. Although depression is one of the most prevalent diseases in primary care practice, consult for receiving help is carried out much less than true prevalence of the disease. Therefore gathering information about prevalence and risk factors of depression is very valuable. Beck Depression Inventory [BDI] which is a screening tool for depression can be used in Iranian patients because of availability of a validated translation. The objective of this study was to estimate the prevalence of depression in infertile subjects in an infertility center
Materials and Methods: in this study, 681 infertile women were evaluated in Shariati Hospital, Tehran. Demographic information's including age, duration, type and cause of infertility, level of education, previous treatments and smoking habits were recorded. BDI was completed by patients and score was estimated. Score of 16 and higher was assumed positive
Results: there was no relationship between age and prevalence of positive BDI score, but prevalence of positive BDI score was higher in infertilities of longer duration, infertilities caused by both male and female factors and in patients with low level of education and history of previous treatment or surgical therapy
Conclusion: infertile patients are at risk of depression. Rate of consulting with psychiatrists and getting help is low in our country due to cultural aspects, so screening of high risk subgroups in infertile patients and referring them to psychiatrist would be very helpful
