Traces of cobalt (II) can be determined by adsorptive stripping voltammetry using Nitroso-S as complex forming reagent. First in acetate buffer pH 5.0, cobalt (II)-Nitroso-S complex was adsorbed on the carbon paste electrode with an accumulation potential of +0.1 V. Following this, adsorbed complex was detected by cathodic differential pulse voltammetric scan from +0.1 to -0.6 V. The effective parameters in sensor response were examined. The detection limit of Co(II) was 1.8 μg l-1 and relative standard deviations for 10 and 100 μg l-1 of Co(II) were 0.8 and 1.2%, respectively. The calibration curve was linear for 3.3-187.1 μg l-1 Co(II). This technique does not use mercury and therefore, has a positive environmental benefit. The method, which is reasonably sensitive and selective, has been successfully applied to the determination of trace amount of Co(II) in water samples. © 2011 by ESG.

The Middle - Late Devonian boundary is investigated based on twenty-two conodont species and subspecies from three sections in the north and west of Kerman, southeastern central Iran. Upper Givetian - lower Frasnian carbonates of the basal part of the Bahram Formation transgressively overlie the sandstone beds of the top of (?) Early - Middle Devonian Padeha Formation. These massive skeletal limestones encompass the G-F boundary. The base of Frasnian is identified by the appearance of early forms of Ancyrodella rotundiloba. It helps to compare our biozones to those of global stratotype in southern France. A new species, Polygnathus hojedki n. sp. is described here. New range is suggested for P. praepolitus.

An organo-nanoclay is used as a new, easily accessible, and stable solid sorbent for the preconcentration of trace amounts of rhodium ions from aqueous solution, this followed by its determination by flame atomic absorption spectrometry (FAAS). Rh(III) ion was first complexed with 2,3,5,6-tetra(2-pyridyl) pyrazine (TPPZ) at pH values between 3.0 and 4.7, and then the complex was then adsorbed onto the nanoclay. The rhodium ions were eluted from the sorbent with HCl. The rhodium in the effluent was determined by FAAS. The linear analytical range is between 0.14 ng mL -1 and 20.0 μg mL -1 in the initial solution, the relative standard deviation at 2.0 μg mL -1 of rhodium is 2.6% (n=8), the detection limit is 0.03 ng mL -1, and the preconcentration factor is 140. Experimental parameters including the pH, eluent type, interference by other ions and breakthrough volume were optimized. The method was applied to the determination of rhodium in water, road dust and synthetic samples. © 2010 Springer-Verlag.

Today, due to developing communicative technologies, computer games and other audio-visual media as social phenomena, are very attractive and have a great effect on children and adolescents. The increasing popularity of these games among children and adolescents results in the public uncertainties about plausible harmful effects of these games. This study aimed to investigate the correlation between computer games and behavioral problems on male guidance school students.This was a descriptive-correlative study on 384 randomly chosen male guidance school students. They were asked to answer the researchers questionnaire about computer games and Achenbachs Youth Self-Report (YSR).The Results of this study indicated that there was about 95% direct significant correlation between the amount of playing games among adolescents and anxiety/depression, withdrawn/depression, rule-breaking behaviors, aggression, and social problems. However, there was no statistically significant correlation between the amount of computer game usage and physical complaints, thinking problems, and attention problems. In addition, there was a significant correlation between the students place of living and their parents job, and using computer games.Computer games lead to anxiety, depression, withdrawal, rule-breaking behavior, aggression, and social problems in adolescents.

A carbon paste electrode (CPE) modified with ferrocenedicarboxylic acid (FCD) and carbon nanotubes (CNTs), was prepared for determination of epinephrine (EP) in the presence of acetaminophen (AC). The electrochemical response characteristics of the modified electrode toward EP and AC were investigated by differential pulse voltammetry (DPV). The results showed an efficient catalytic role for the electro-oxidation of EP and AC, leading to a remarkable peak resolution (~250 mV) for two compounds. Under the optimum conditions, the calibration curve for EP was obtained in the range of 5.0×10-8 to 4.5×10-4 M. The proposed method was applied to determination of EP and AC in real samples and the obtained results were satisfactory. © 2011 by ESG.

A sensitive and selective electrochemical method for the determination of amoxicillin (AMX) was developed using a ferrocenedicarboxylic acid modified carbon natubes paste electrode (FDCCNTPE). The modified electrode exhibited good electrocatalytic activity for electrochemical oxidation of amoxicillin at the pH of 10.5 phosphate buffer solution. The diffusion coefficient (D= 4.62 ×10-5 cm2 s-1), and the kinetic parameter such as the electron transfer coefficient (α= 0.494) of AMX at the surface of FDCCNTPE were determined using electrochemical approaches. Under the optimized conditions, the electrocatalytic oxidation peak current of amoxicillin showed two linear dynamic ranges with a detection limit of 8.7 nmol L-1), amoxicillin. The linear calibration ranges was in the range of 0.03-0.35 μmol L-1 and 0.50-32.70 μmol L-1), amoxicillin using square wave voltammetric method. Finally, this modified electrode was also examined for the determination of amoxicillin in real samples such as drug and urine. © 2011 by ESG.

Background & Aims: Migraine is a common clinical and chronic disorder. The rate of psychological problems is high among these patients. This study examined the relationship of perfectionism dimensions and personality type with migraine headaches. Methods: This was correlational study on 68 patients referring to neurologists in the city of Kerman, Iran. Participants responded to personality type and intensity of headache questionnaires and multidimensional perfectionism scale (MPS). Data were analyzed using regression analysis. Results: A significant correlation was found between type A personality and dimensions of perfectionism, and migraine. Moreover, type A personality and community-oriented and self-oriented perfectionism are predictors of migraine, but other-oriented perfectionism is not a predictor of migraine. Conclusion: The results of this research showed that personality characteristics, especially type A that is associated with a kind of pressure and time urgency, and perfectionism of patients with migraine should be considered in any treatment. © 2015, Kerman University of Medical Sciences.

Background & Aims: Body image represents the attitude of the individual toward himself/herself, along with the feelings and thoughts that can change individuals’ behavior in various conditions and in the positive or negative direction. In neurotic perfectionism, extreme tendency to perfectionism, obsessive thoughts, impulses, or unwanted images can be observed that can damage women’s perception toward visual beauty and body image, and physical attraction. Dieting is a method by which body image can be improved. Methods: This correlational study was conducted on 109 patients referred to a specialized nutrition and diet therapy clinic. The participants were selected using systematic sampling. In order to collect data, the Multidimensional Body-Self Relations Questionnaire (MBSRQ), Frost Multidimensional Perfectionism Scale (FMPS), and Obsessive Beliefs Questionnaire-44 (OBQ-44) were used. Data were analyzed using the SPSS 18 software. Results: A significant relationship was observed between body image, neurotic perfectionism, and obsessive thoughts. About 26% of the variances in the criterion variable (body image dissatisfaction) could be explained by the predictor variables of neurotic perfectionism and obsessive thoughts. Further evaluation of the two predictor variables showed that only neurotic perfectionism had a significant relationship with body image dissatisfaction. Conclusion: Due to the importance of nutrition in women's health, a careful evaluation of and consultation for the patients seem necessary before providing them with a diet plan. The evaluation of perfectionism and obsessive thoughts in patients can predict the success of the diet programs. © 2016, Kerman University of Medical Sciences. All rights reserved.

Smoking is the most common and cheapest addictive substance and has physical, psychological, and social side effects. Personality traits and low self-control have been identified as key factors for substance and tobacco abuse. This study examined the relationship between personality traits and self-control, and symptoms of nicotine dependence in male prisoners.This was a descriptive correlational study. The research sample consisted of 384 male prisoners in Kerman, Iran. The participants were selected using simple random sampling method. The data collection tools consisted of the NEO five factor personality inventory (NEO-FFI), self-control Inventory, and the nicotine dependence symptoms inventory.The mean age of the prisoners was 35.33 9.28 year. The results showed a significant negative relationship between self-control and nicotine dependence. The most important predictors of prisoners self-control were the personality traits of conscientiousness, neuroticism, openness, and temperamental neuroticism, respectively. The most important predictors of nicotine dependence in prisons were personality traits of adaptability, temperamental neuroticism, extroversion, and openness, respectively.Personality traits and self-control have an important role in nicotine dependence; therefore, by training self-control, behaviors such as smoking and consumption of drugs can be reduced.

The aim of the present study is to compare time perception among drug addicts and controls.30 drug addicts were selected, and 30 non-addict individuals were selected as the control group. The two groups performed three tests of time reproduction, time estimation, and time discrimination.There was a significant difference between the addicts group and the control group regarding the error of time reproduction and time estimation. The addict group in comparison to the control group had a lower under-reproduction and a higher over-reproduction error, and also a lower under-estimation and higher over-estimation error. However, regarding time discrimination, no significant difference was observed between the errors committed by both groups. On the other hand, when showing images of drug consumption tools and normal images with same durations, the normal group believed that the images related to drug consumption tools were shown for a shorter period of time.Time perception is different between morphine-derived drugs addicts and controls.
