As police forces work in STRESSful conditions, this article is intended to study, appraise AND deal with STRESS resources, repercussions, AND STRESS adjusters among police forces. Both individual AND organizational factors can produce STRESS for police forces but different researches have shown that organizational factors more than personal factors contribute to STRESS in police work. STRESS can have different behavioral, psychological AND physical repercussions which are not the same due to different organizational AND individual characteristics. police forces are not the same in confrontation AND APPRAISAL of STRESS. Confrontation of police forces with STRESSful conditions has a unique characteristic. Police forces at the beginning AND during the PRIMARY APPRAISAL experience a lot of challenges in the situation, but in continuation or in a SECONDARY APPRAISAL they consider the situation resolvable. Police forces in PRIMARY APPRAISAL are totally under the influence of situation but they are not so in SECONDARY APPRAISAL, in fact in SECONDARY APPRAISAL they show some sort of stability in confrontation with different STRESSful situations. Furthermore the police forces who are older appraise the situation positively AND more resolvable than younger police forces. police forces due to the nature of their work used confrontation style which is different from ordinary people.

Purpose: Managers are one of the important elements of an organization, for this reason, in order to draw the future of the organization, it is necessary for the planners to specify the conditions of their selection AND appointment. Therefore, the current research has been done with the aim of identifying AND analyzing the components of selecting future principals.Method: In this research, comparative AND benchmarking method is used as a prospective approach. This approach is based on the belief that today's advanced organizations/countries can be considered as a model for the future of another organization/countries in their respective subjects. For this, first, the fields of comparison AND benchmarking were determined using Brody's four-step comparison method; then the countries of Canada, FinlAND, Australia, South Africa, AND Japan were selected according to the qualitative balance value in the international advanced TEAMS test, human development index, life quality index(health, instruction, AND welfare), education quality index, AND other scientific-scholarly indexes; finally, by extracting the criteria for the selection AND appointment of principals through content analysis AND comparison with Iran, the proposed framework for Iran has been presented.Findings: A total of 61 components for the selection of SECONDARY school principals were identified from among the studies conducted in the selected countries in this article. By extracting the commonalities AND differences of each of the components among the countries, it was found that the highest index of manager selection AND appointment belongs to Japan AND the lowest one is related to FinlAND.Conclusion: There are similarities between the components of selection of principals of SECONDARY schools in Iran AND selected countries. In Iran, special attention should be paid to important components such as adherence to religious principles, appropriate personality traits, creativity AND innovation, motivation to develop capabilities, professional growth, power of supervision AND accountability, social image, leader skills, AND purposefulness AND foresight.

More than 22% of the world's agricultural lAND is saline, AND this trend continues to increase with climate changes. Salinity STRESS causes leaf color change, osmotic STRESS, ionic toxicity, prevents growth, photosynthesis AND plant performance. Due to their size less than micron, metal nanoparticles have a great absorption AND transmission power in plants. Salinity STRESS is a major problem in hot AND dry areas under tomato cultivation. For this purpose, investigating the mutual effects of the size AND type of zinc oxide AND iron oxide nanoparticles on the improvement AND change of growth AND increasing the resistance to salt STRESS in tomato plants of the early urbana variety were carried out in the form of a completely rANDomized AND factorial design with 4 replications, at a significant level of 5%. In this research, zinc oxide nanoparticles in 25 AND 50 nm sizes, iron oxide in 25 nm sizes AND sodium chloride in 0 AND 75 mM levels were used. Nanoparticles AND salinity treatments were both applied to the plants. The results showed that salt STRESS led to a decrease in plant growth parameters such as shoot AND root length, leaf area, RWC, ion leakage. Also, NaCl led to an increase in the accumulation of prolin AND other aldehydes, sodium, iron AND zinc. The application of nanoparticles had a slight effect in STRESS-free conditions, but in STRESSed conditions, these two nanoparticles alone AND especially in combination neutralized the effect of salinity AND reduced the damage caused by salinity STRESS.

To investigate the effects of water deficit STRESS AND bio AND non-bio fertilizers on Thymus Vulgaris, a split plot experiment was conducted based on rANDomized complete block design with three replications in 2017 in Asgarya agricultural field in Yazd. The treatments included water tension: W1=7 (Control), W2=12 AND W3=17 days irrigation intervals as the main factor AND bio AND non - bio fertilizers at five levels including B1= control (without fertilizer), B2= endo mycorrhiza (Glomus), B3= Azospirillum bacteria, B4= Pseudomonas bacteria AND B5= chemical fertilizer (NPK) a sub – factors. Results showed that the highest flowering branches yield, a, b, AND total chlorophylls AND nitrogen AND phosphorus elements were observed in 17 days of irrigation (W3). 12 days of irrigation treatment (W2) showed the highest potassium element rate. The highest a, b AND chlorophylls AND nitrogen were observed in Azospirillum treatment (B3). The highest total chlorophyll, phosphorus element, carotenoids AND flavonoids were observed in Pseudomonas treatment (B4); the highest potassium element rate were obtained in mycorrhiza treatment (B2); the highest flowering branches yield were observed in NPK treatment (B5) AND control (B1) treatment resulted in the highest anthocyanin

To study the effect of salinity STRESS on some physiological traits in wheat cultivars (Triticum aestivum L.), a factorial experiment based on rANDomized complete block design with three replicates was performed at 2017 in the research greenhouse of Agronomy Department, University of Tehran. Salinity treatments at two levels; control (1.2 dS/m) AND sodium chloride treatment (16 dS/m) AND seven wheat cultivars, Rowshan, Inia-66, Mahdavi, Khazar-1, Karaj-2, Ghods AND Shole were the experimental treatments. According to the results, relative water content, yield AND its components AND potassium/sodium ratio decreased in all genotypes while Na+ content AND remobilization of carbohydrates were increased. Salt resistant varieties, Roshan AND Inia-66, had the highest level of relative water content, remobilization of soluble carbohydrates AND number of grains per spike. In addition, Roshan cultivar showed the highest potassium concentration AND K+/Na+ in the shoots, while Ghods AND Sholeh as sensitive cultivars had the highest sodium concentration in the shoots. Findings showed that the ability of a cultivar to remobilize soluble carbohydrates is one of the traits that determine salt STRESS tolerance, hence, this trait is suitable for evaluating salt tolerance of wheat cultivars in the future investigations.

To investigate the effects of fertilizer regimes on quantitative AND qualitative traits of Dracocephalum kotschyi Boiss, a field experiment at three replications with the Split Plate arrangement in a completely rANDomized block design was conducted in the Research Field of Tarbiat Modares University during the 2017-18 growing season.Water deficit STRESS (irrigation after discharging 20 (optimal irrigation), 40 (mild water deficit STRESS), 60 (moderate water deficit STRESS) AND 80% (severe water deficit STRESS) of water used (available water)) in the main plot AND fertilizer regime (urea, nitroxin, vermicompost, azocompost AND no fertilizer) in the subplot were studied. The results showed that the highest leaf fresh weight (1797 kg ha-1) AND total biomass (2957 kg ha-1) were obtained by application of urea in mild water deficit STRESS condition AND the highest dry matter digestibility percentage was observed in azocompost treatment in moderate water deficit STRESS condition (57.8%). The highest crude protein was produced in severe water deficit STRESS condition (19.72%) AND moderate water deficit STRESS (18.4%), respectively.. The highest percentage of water soluble carbohydrate AND neutral detergent fiber were obtained from no fertilizer in moderate water deficit STRESS (22.06%) AND application of urea in severe water deficit STRESS conditions, respectively. Mild water deficit STRESS application to produce high biomass is recommended for Dracocephalum kotschyi Boiss. According to the results, application of urea in mild water deficit STRESS was selected as the best treatment to produce forage 32% more than control.

A questionnaire survey was used to investigate the prevalence, sources, AND consequences of STRESS among Iranian PRIMARY school teachers. Ten schools from district 4 of Tehran were rANDomly selected from the Iranian Ministry of Education Public School list, AND from each one of these schools, 8 teachers were chosen, leaving a final sample of 80 full-time, PRIMARY school teachers. Data was collected via researcher- built questionnaire. The questionnaire consisted of three sections. The first section requested individual demographic information regarding sex, age, education status AND teaching experience AND a series of other variables which have been considered to be an issue of concern in the teaching profession. Section two corresponded to assessment of occupational STRESS. Section three evaluated correlated of occupational STRESS.The main purposes of this study were to: 1) specify the prevalance of STRESS among iranian PRIMARY school teachers at work, 2) determine the sources of work pressure perceived as most STRESSful by PRIMARY school teachers, AND 3) pinpoint the correlated of work STRESS as an introductory validation procedure towards the development of a new inventory to assess Iranian teachers' STRESS.The results of this study revealed high levels of work STRESS prevalent among elementary school teachers. Significant findigs were found regarding few demographic variables. The most significant sources of work STRESS involved a variety of aspects of the teaching profession. Factor analysis supported the multidimentional rather than unidimentional nature of teachers' work STRESS. Finally, the most important consequences included "dissatisfaction from job", "boredom", "occupational self-devaluation", AND "apathy towards job".
