The present study examines psychopathic deviate tendency and psychopathology relationships and the possible gender differences in them in an Iranian adolescents and youth sample. The sample included 106 adolescents (55 females and 51 males) and 94 youth (45 females and 49 males) that were randomly selected from Eghlid city, Fars province, Iran. We speculated a possible linkage between psychopathology and psychopathic deviate tendency among adolescents and youth on the basis of developmental psychopathology and related literature. A demographic questionnaire, the Minnesota Multiphasic Personality Inventory-2, scale-4, and the Symptom Check List 90 Revised were used in this study. Analysis indicated that psychopathic deviate tendency and psychopathology indices were linearly related in adolescents and youth. There are significant positive correlation coefficients between the psychopathic deviate tendency and psychopathology including somatisation, obsessive-compulsive disorder, anxiety, interpersonal sensitivity, aggression, phobia, paranoid ideation, psychosis, atypical factors and SCL-90-R. However, significant correlations between psychopathic deviate tendency, somatisation and phobia are elements that give a new insight into this research. A multivariate analysis of variance conducted by gender-age group and gender-age group interaction as independents and the psychopathic deviate tendency and psychopathology indices as dependents variables that reject their significant effects in both dependents' variables. Finally, the multiple regressions indicated that paranoid ideations, somatisation and aggression, somatisation, depression, and somatisation predict psychopathic deviate tendency in females, males, adolescence, youth, and total sample respectively.

In this study, the resistance spot welding (RSW) process of the galvanized interstitial free (IF) steel sheets and galvanized bake hardenable (BH) steel sheets, used in the manufacturing of car bodies, has been modeled and optimized. The quality measure of a resistance spot welding joint is estimated from the tensile-shear strength. Furthermore, four important process parameters, namely welding current (WC), welding time (WT), electrode force (EF), and holding time (HT) are considered as the factors influencing the quality of the joints. In order to develop an accurate relationship between the process inputs (4-component vectors) and the response output (tensile-shears strength) at first a linear regression model was utilized but the residuals analysis revealed a non-linear behavior. Therefore, an artificial neural network (ANN) was proposed because the ANNs are capable of mapping the non-linear systems. A back propagation neural network model was developed to analyze RSW process and the interaction effects of the parameters. In the second phase of this research, Genetic Algorithm with the fitness function based on an ANN model was employed as an optimization procedure for determining a set of process parameters; as a result, the maximum joint strength was obtained. Optimization results showed high compatibility with the actual experimental data. © 2011 Elsevier Ltd.

In order to evaluate the effect of Azosprillium inoculation and molybdenum application on common barley grown in saline condition, a greenhouse experiment was conducted at Azad university, branch of Eghlid, Iran. The experimental design was factorial based on complete randomized design with four replications. The first factor comprised of four salinity treatments (1 as control, 5, 10 and 15 ds m-1), second factor comprised the levels of Mo application (1: treated and 2: untreated = control) and the third factor included two levels of Azosprillum inoculation (inoculated and uninoculated = control). The measured parameters were chlorophyll fluorescence, photosynthesis (Ps) rates, carbohydrates, nitrate, ammonium and protein content, nitrogenase activity, grain yield (GY) and yield components. The results showed that salinity decreased GY in all levels. GY reduction in inoculated treatment was lower (12.9%) than uninoculated treatment (29.7%). GY reduction was highly related to the reduction of grain number (GN) rather than reduction in ear mX2. Inoculation and application of Mo reduced harmful effects of salinity especially on mean kernel weight and grain number. Soluble saccharides and protein contents increased with increasing salinity. Inoculation and Mo application significantly increased the content of fructan and sucrose respectively. The mean values of Fv/Fm and photosynthesis rate reduced in the salinity treatments compared to the control. Inoculation and Mo application significantly increased photosynthesis rates at all salinity levels. The highest plant N content was obtained from inoculated, control salinity treatment by applying Mo. In inoculated barley roots with application of Mo, nitrogenase activity (NA) was not severely inhibited by salinity. Data also showed that Mo application positively affected nitrogenase activity. Inoculation, caused plant to cope on the stress, effectively by increasing fructan content and NO3/NH 4 ratio and lower decrease in whole plant N content and Fv/Fm ratio. Generally, Azosprillium inoculation helped plants perform better under salinity treatments and Mo application ameliorated plant nitrogen status.

The purpose of this study was to examine the relationships of impulsivity, aggression, and psychopathic deviation and to investigate the roles of age and gender on these constructs in an Iranian sample. The sample consisted of 165 adolescents and 156 young adults who were randomly selected from Shiraz, Iran. A demographic questionnaire and three inventories were used in this study. Impulsivity and its subscales were significantly positively correlated to psychopathy deviation in this sample. There was no significant effect of gender on these variables among adolescents and young adults. Altogether, cognitive impulsivity and verbal aggression explained 5% of variation in psychopathy deviation among this sample. © 2013 Copyright Taylor and Francis Group, LLC.

The purpose of this study was to examine the effects of psychopathology and personality on opiate substance abuse, and also to investigate the roles of marital status, income, educational level, and familial history of drug abuse and family size, as well as ethnicity, in determining substance abuse. There were 150 young adult male participants divided into three groups; these comprised twelve-step treatment programme abstainers, opiate addicts and normal individuals, respectively. A demographic questionnaire, the SCL-90-R, and the NEO PI-R were used in this study. The study data demonstrated significantly positive and negative correlations between the Neuroticism and Extraversion dimensions of personality and all indices of psychopathology. Patients with opiate use had significantly higher levels of psychopathology than the other two groups. The twelve-step self-treatment programme significantly lowered psychopathology in patients with opiate abuse. In addition, normal individuals had a significantly lower level of Neuroticism and higher levels of Openness to Experience, Agreeableness and Conscientiousness than either opiates abusers or abstainers. Lastly, the results of the study indicated the effects of familial history of substance abuse and family size on prospective drug abuse.
