the role of cognitive, metacognitive and metaemotional factors in psychological distress has been clearly confirmed. The current research study aims to examine a psychological distress model based on intolerance of uncertainty and emotional schemas of cancer patients with the mediating role of metacognitive beliefs and cognitive avoidance.

regarding the methodology, the present study relies on correlation and structural equation modeling. The study sample included 300 cancer patients who visited various hospitals in Tehran and completed the questionnaires of uncertainty intolerance, stress, depression and anxiety, emotional schemas, metacognitive beliefs, and cognitive avoidance.

findings demonstrated that the proposed model has appropriate fitness among cancer patients. Also, the relationship between mediating variables and endogenous and exogenous variables is significant. The variables under investigation explained 46 percent of psychological distress variance in the patients.

Psychological distress in cancer patients is affected by interaction of excessive emotional states, intolerance of uncertainty, such as metacognitive beliefs and emotional schemas.

This study seeks to explain the intimacy of marriage based on psychological coping styles and resilience in women with emotional divorce. The research is descriptive and correlational. The study population included all women with emotional divorce who referred to centers and psychological clinics and among those 300 were selected. 150 of them were based on research and predictor variables that were selected using multi-stage cluster sampling and responded the questionnaire of emotional divorce Guttmann (2008), marital intimacy Walker and Thompson (1983), coping styles Lazarus - Folkman (1988) and hardiness scale Kiamrsy et al (1377). Data obtained by multiple regression and correlation analysis was performed with SPSS software. The results showed a positive relationship between marital intimacy and problem-focused coping styles. (P<0.01). There is a negative relationship between marital intimacy and emotion-focused coping styles (P<0.05). There is a positive relationship between marital intimacy and psychological hardiness (P<0.01). Also psychological hardiness (Beta =0.434) and problem-oriented coping style (Beta = 0.265) can be changed to significantly predict marital intimacy.

Broomcorn is extensively cropped in Miyaneh region for traditional broom production and occasionally included in rotation with barley by local farmers. The research objective was clarifying of broomcorn allelopathic potential on barley germination and initial growth. Allelopathic properties of 2.5, 5, 7.5, and 10% of broomcorn roots and shoots aqueous extracts sampled 1, 2, 3, and 4 months after planting, also root exudates using equal compartment agar method and 5 and 10% of intact and burnt crop residues aqueous extract on barley germination and initial growth were evaluated. Also, 2.5, 5, 7.5, and 10% of 3-month broomcorn foliar extracts on barley seedlings growth was evaluated in greenhouse condition. Broomcorn root extracts was less allelopathic on barley seed germination, also 3-month foliar was the most allelopathic studied plant organs on seed germination and growth of barley. Also, broomcorn root exudates were more toxic on barley plumule than radicle. Residue burning decreased allelopathic effect of broomcorn residue up to 77%. Irrigating with broomcorn extracts had less allelopathic effects than direct bioassay on barley seedlings in laboratory. Considering remarkable allelopathic potential of broomcorn on barley, its residue management should be concerned in broomcorn-barley rotations.
