In order to evaluate the effect of drought stress on corn germination indices produced under drought stress on a parent plant, experiment was conducted in a completely randomized design with three replications in a Bahar university in 2017. The factors applied to the mother plant were: full irrigation as control (R1), full flowering stage (R2), pod closure (R3), pod filling (R4), seed start (R5), and complete seeding (R6). The results showed that the highest germination percentage, root length, stem length and dry weight of soybean seedlings were obtained in irrigation treatments throughout the plant life (control). No significant difference was observed between the treatments in the traits and the mean germination time. The lowest dry weight was obtained in drought stress at full flowering stage. Drought stress had an impact on the traits studied and it is recommended that soybeans, especially at full flowering stage, do not undergo drought stress.

The purpose of this study was to investigate the effectiveness of Bowen Self-differentiation on assertiveness behaviors among married women in Isfahan. The research method was quasi-experimental pre-test - post-test with control group. Statistical population was all married women in Isfahan. The participants were 60 married women who were selected randomly among the people with low score on Gambrill and Richy (1975) assertiveness questionnaire. Then they randomly assigned into two experimental and control groups (N=30). The experimental group received eight sessions of Bowen Self-differentiation group counseling. The control group received no intervention. The data were analyzed using covariance analysis. The results showed that Bowen self-differentiation counseling had significant effecti on assertiveness behaviors among married women.

The purpose of this study was to examine the effect of the training of problem-solving and decision-making skills on the reduction of addicts’ positive attitudes to narcotics The design of this study was experimental design namely: pre and post test with control group. The population included all addicts referring to Sanandaj self-report centers (500 addicts). By random sampling, 60 addicts were selected and completed the attitude questionnaire to narcotics use. Each of experimental groups was under problem-solving and decision-making skills training for ten 90 minute sessions. No training given to control group. After training, two experimental groups significantly had lower levels of positive attitude to narcotics use. No difference was observed between two experimental groups. The results of this study indicated that the training of problem-solving and decision-making skills can reduce the addicts’ positive attitudes to narcotics.

The objective of present research was to investigate variables predicting divorce according to John Gottman theory among couples in Esfahan. The design of this study was causal comparative. Fromcouples referred to Centers for Divorce Crisis, 150 prsons (male and female) were selected to participate in educational courses. Then, violence starting, unpleasant memories, compensating actions, drowning, love, and interest questionnaires were administered. There is a significant difference among present variables such as violence starting and drowning between divorce-prone and ordinary couples (P < 0./01). Results of Bi valu logistic regression analysis showed that the variables such as drowning, compensating action, love and interest provided the strongest predictors of possibility for divorce-prone couples. Therefore, it is concluded that drowning, violence starting, and four aggressors (objection, disrespect, defense stance and inattention), unpleasant memories increase the possibility of divorce among couples. While increased compensating actions, love and interest decrease the possibility of divorce among couples.

Wild Rats have been implicated as potential reservoirs of Cryptosporidium spp., thereby responsible for transimission of the infection to humans by acting as natural sources of C. parvum, a zoonotic species. Recently, and possibly due to much closer and more frequent contacts to these animals, concerns have raised about spread of the disease among human environments. The purpose of this study is molecular characterization of Cryptosporidium in rats of Tehran. Rats were hunted randomly from different zones of Tehran and their stool samples were studied by Polimerase Chain Reaction (PCR) method using 18s rRNA gene. Subsequently, positive (i.e. infected) samples were characterized and sequenced. Reported rates of Cryptosporidium infection among 77 rats by implementation of staining as well as nested PCR methods were %13 and 27.3 %, respectively. In order to recognize type of infective agent, all positive cases were tested by PCR – RFLP (Restriction Fragment Length Polyformism) method by which C. parvum pattern was obsereved.. The obsereved patten inPCR-RFLP test was checked via sequence determination method in all positive isolations and the results were approved. The results reveal that wild rats in Tehran are reservoirs of C. parvum that could be transmitted to humans. Also, it illuminates hygienic importance of freewildrats eradication throughout the city.

This research was to study the effect of positive induced emotions on happiness and depression after lingering induced arousal worry.

To study the effect of emotion induction (Positive and negative) on decreasing previously induced anxiety, 32 female students at high school grade 1 in Isfahan City, were randomly selected and then questionnaires of depression, happiness, MMPI 2 (Personality multiple questionnaire) and two scales of the big five factorial questionnaire (extraversion-introversion) was completed by them. Then they were randomly assigned into four groups (two experimental groups and two control groups) for the first group a sad film, the second group a cheerful film and the third group a neutral film was shown and the fourth group remained without intervention. Next day, all group members completed the depression and happiness questionnaire again. Research findings were analyzed using covariance and MANOVA analysis.

Those who turned their attention to cheerful film were happier than those who saw either the neutral and sad film or non intervention and those who saw sad film were more depressed than others.

Positive emotion is more effect on negative emotion like depression and happiness. This effect called the undoing effect of positive emotions.
