Although several studied have been carried out to use ferrate (VI) for wastewater treatment, there is no study on removal of floating diesel fuel from water by using ferrate (VI) oxidation process. The aim of this study is to remove floating diesel fuel from water by using ferrate (VI) oxidation process. In this study electrochemical method is utilized to generate ferrate (VI). With changing hydraulic retention time (HRT), pH and ferrate (VI) concentration, the optimum conditions of diesel fuel removal are determined. The results show that the optimum HRT for diesel fuel removal from water by using ferrate (VI) oxidation process is 10 min. Although increasing of HRT to more than 10 min can increase the performance of diesel fuel removal, this increment is not significant. The usage of ferrate (VI) in the range of 0.05 to 20 mg/L is able to remove 90 to 100% of diesel fuel from water. Acidic environment is the optimum condition for diesel fuel removal by ferrate (VI) oxidation process. However, decreasing pH to acidic condition do not have a big effect on the diesel fuel removal. This study reveals that diesel fuel can be removed by using ferrate (VI) oxidation process with high efficiency. However, more studies are needed to understand whether removal of diesel fuel by using ferrate (VI) oxidation process is an economic process.

Aim: The study aimed to compare the effects of positive and negative induced false memory and true memory people in the symptoms of anxiety-depression and normal individual.
This study designed the quasi-experimental study posttest with control group. In this study¡ first created scale depression¡ anxiety and stress (DASS) completed. The students participating in this study¡ 29 subjects with symptoms of depression-anxiety to be the experimental group and 29 patients without symptoms who were selected as the control group. The first of two groups in term of false memory was normal mood. Then the two groups in terms of positive and negative mood were assessed by false memory. The results were analyzed using two-way analysis of variance.
The results showed that the experimental group and the control group in terms of recognition and the false note in terms of positive and negative mood¡ while there is no difference between the two groups of the recall and correct recognition.
Positive and negative mood state¡ depression-anxiety increase false memory.

This study aimed to determine the effectiveness of dialectic behavior therapy to increase the differentiation of self in women with borderline personality disorders and drug abuse was conducted. Experimental research designs with a single subject using the multi-stepped base lines were used. Based on the desire to participate in the research, structured diagnostic interview and entry criteria, among female patients with borderline personality disorders and substance abuse, four people were chosen. All four subjects were dialectic behavior therapy sessions during the twelve. In order to assess the differentiation of self-differentiation of self-DSI-R questionnaire by Askvern (1998) was built, was used. Dialectic behavior therapy can dramatically increase the differentiation between themselves in women with borderline personality disorders and substance abuse, so that scores during the intervening twelve sessions has increased substantially compared to baseline scores. Graphs review the effectiveness and effect size indicates a significant increase in participants was self-differentiation. Dialectic behavior therapy interventions can be effective in helping to increase the differentiation of self and a good practical implication in the treatment and prevention of substance abuse.

The brain laterality is meant to make a difference in the function of both brain hemisphere and may be associated with some components of mental health. Therefore, the aim of this study was to evaluate of empathy, stress, anxiety, and depression in lefthanded and right-handed medical and paramedical students. The study design is a causal-comparative. The study population included all students of Kermanshah University of Medical Sciences in 2013-2014. The sampling was conducted on a stratified random procedure and 168 people were studied. The research instruments were including Edinburgh handedness inventory, Baron- Cohen scale for empathy quotient, and depression, anxiety, and stress Scale (DASS). Finally, SPSS 20 was utilized to analyze the data using multivariate analysis of variance. The results showed there is only significant differences between the groups in term of emotional reactivity subscale and levels of emotional reactivity is higher in the left-handed group. Similarly, there is significant difference between the left-handed and right-handed groups in term of the rate of anxiety and anxiety levels were significantly higher in the right-handed people. However, there was no difference between the groups in terms of stress and depression. The laterality of the brain hemispheres is a determining factor in the emotional and psychological state of individuals; So that increased emotional reactivity in left-handed people is justified due to the fundamental role of the right hemisphere in expressing emotions. The findings related to anxiety are debatable.

Comorbidity between Borderline personality disorder and substance abuse disorder is very high. The present study examined the effectiveness of dialectical behavior therapy on negative emotion regulation strategies in women with borderline personality disorder and substance abuse. Based on the willingness to participate in the research, structured clinical interview and the criteria for inclusion, of female patients with borderline personality disorders and substance abuse 4 people were purposefully selected. These four participants underwent emotion regulation techniques of dialectical behavior therapy for 12 sessions. In order to measure negative emotion regulation strategies, Garnesfky cognitive emotion regulation questionnaire was used. To analyze the collected data, visual analysis of charts and trend indicators, stable, percentage of non-overlapping data and percentage of overlapping data was used. Emotion regulation techniques of Dialectical behavior therapy reduced the scores of negative emotion regulation strategies in women with borderline personality disorders and substance abuse. A review of the effectiveness charts and the amount of effect represented a significant reduction in the use of negative emotion regulation strategies (including self-blame, rumination, blaming others and catastrophizing) in participants. Dialectical behavior therapy is useful in the reduction of the use of emotion regulation strategies (including selfblame, rumination, blaming others an catastrophizing). It seemed these techniques can be useful in the treatment of women with comorbidity borderline personality disorders and substance abuse.

This study aimed to examine the effect of dialectic behavior therapy on the reduction of impulsiveness in women with comorbidity of borderline personality disorders and substance abuse. An experimental single system research design using multiple baselines was employed for this study. Based on the structured diagnostic interview and entry criteria, four participants among female patients with borderline personality disorders and substance abuse were selected via purposive sampling method. All four subjects received twelve dialectic behavior therapy sessions. Then, Impulsiveness Bart Scale (IBS) was used to measure impulsiveness. Dialectic behavior therapy led to the significant reduction of impulsiveness scores in women with borderline personality disorders and substance abuse. Graphs pertaining to the effectiveness and effect size indicate a significant decrease in participants’ impulsiveness. Dialectic behavior therapy interventions can contribute to the decrease of impulsiveness and bring about desired practical implications in the treatment and prevention of substance abuse.

The aim of this study was to compare the theory of mind in normal children and irresponsible. The method of study was casual comparative, the population consists of children 9 to 12 years normal or irresponsible condition in the 92-93 academic year study in Isfahan city. Multi-stage stratified random sampling method was that the boys school, six areas were selected in Isfahan. Instrument included a questionnaire Hop theory of mind (1994) and data analyzed using multivariate analysis of variance. The result showed that the two groups of children differenced general level and three levels of detail (level I, II and III) there is a theory of mind (P<0/01). Based on the results of this study, it can be claimed that children with irresponsible parents, due to their parent's authoritarian and permissive style, have lower level of of evolution of theory of mind than normal children. Because parents with authoritarian and permissive parenting style have less social interaction with their children which leads to weaker development of theory of mind.

The present study was an attempt to examine the difference in the profile of working memory، auditory working memory، and spatial working memory between drug، stimulant، and methadone abusers and normal people. This study was a causal-comparative one with between-group comparison methodology. All the individuals addicted to opiates، stimulants، and methadone who had referred to Khomeini treatment centers of the city from September 2013 to February 2014 constituted the statistical population of the study. The number of 154 abusers (54 drug abusers، 50 stimulant abusers، and 50 methadone abusers) and the number of 50 normal participants were chosen as the sample of the study by purposive sampling method. The participants responded to Wechsler Memory Scale—third edition (WMS-III). There was a significant difference between the normal group and drug، stimulant، and methadone abusers in terms of working memory، auditory working memory، and spatial working memory. Drug and stimulant use leads to sustained damage in cognitive processes such as working memory. However، research indicates that these cognitive processes will improve with the passage of time.
