Suburban villages are important because of their spatial and functional proximity, according to their livability level and the role of local management, as well as their own attractions and tourism conditions. In the last two decades, managers and policymakers who were involved in developing such areas, have sought to strengthen and diversify income sources for the residents of these areas and plan to organize activities and programs in suburban areas. One of these sources is the foundation and development of tourism in suburban areas using their own attractions.Suburban tourism is a different aspect of visitors' travel outside their homes and cities to the surrounding areas for vacations, enjoying day and short-term trips, recreation, fishing, and hunting, being in the heart of nature. This includes meetings with friends and relatives. In addition, taking advantage of silence and peace, fresh air, wide open spaces, and escaping from urban congestion are enjoyable.The literature on rural development management shows that institutions, as formal and informal organizations, play an undeniable role in environmental and territorial management behaviors, including village quality. Local administration (including village administration and village Islamic council) can effectively increase the quality of life and tourism capacity. In addition, constructive interactions between local managers and residents play a significant role in the overall development of the village.With the development of livability, the possibility of tension and conflict between people and tourists will decrease, more participation in planning and decision-making in the tourism industry will be made, and the sustainable tourism development will be realized; therefore, it is necessary toinvestigate the role of local management in the development of livability, and then analyze the role of livability in the development of tourism in suburban villages.Allahabad village of Yazd province, because of its close location to the city of Zarch and its relatively long history, when having historical attractions belonging to before Islam and the peaceful coexistence of Zoroastrian and Muslim residents, is in the category of famous and interesting villages of Yazd. Despite the tourism capacities, the local administration's lack of attention to these capacities has caused problems for the village. By identifying weaknesses and being aware of opportunities with the comprehensive cooperation of local managers and residents, the path to achieving the development of livability and tourism in this suburban area can be made smoother. The present research deals with the analysis of rural management of Allahabad in increasing the quality of life and tourism development in this region, and aims to achieve accurate results in line with the purpose of the research.The notable feature of the current research is that it analyses four different dimensions of livability with local management in a village and believes that if there is a direct relationship between local management and the livability of the village in all dimensions, then with the improvement of management, a place can achieve optimal livability and provide the basis for tourism development. Therefore, the present study attempts to address the research gap by examining the relationship between the three factors of local management, livability, and tourism development potential in a village around the city.

The research method used is a descriptive-correlation type of research in terms of its practical purpose with a survey nature and according to the way of data collection. The statistical population of this research included all the local residents of Allahabad village in Yazd in April 2022 (5573 people based on the census of the whole country in 2015) and 363 people were selected as the research sample by using random sampling and using Cochran's formula.In this research, a questionnaire designed with four sections including variables of local management, economic, social and environmental viability was used in the form of a five-item Likert scale from completely disagree (1) to completely agree (5). The validity of the questionnaire was calculated and confirmed by Cronbach's alpha test. In order to investigate the relationship between research variables, Pearson's correlation coefficient was used and finally the research hypotheses were tested with the structural equation model.

The average of local administration (village administration and village Islamic council) (M=2.78) in a five-choice spectrum showed that the respondents evaluated local administration (village administration and village Islamic council) at an average level. The average dimensions of economic, social and environmental viability showed that the respondents rated these three variables as average. Economic, social and environmental viability has a significant and direct relationship with local management (village Islamic council).The intensity of the relationship between economic environment and local management (village Islamic council) is reasonable but higher than other variables (r=0.81, p<.001). Social viability is most related to economic viability. Compared to social viability and local management (village administration and village Islamic council), environmental viability is more related to economic viability (r=0.79, p<.001). The results of the correlation prove that with the improvement of the situation of local management (village administration and village Islamic council), the economic, social and environmental viability will also improve. In the final model, although local governance has a direct impact on economic viability, it also has a direct impact on social viability. Another finding showed that local management has a direct impact on environmental viability.

The results of the research findings show that economic, social and environmental viability has a direct and meaningful relationship with local management (village administration and village Islamic council), and the intensity of the relationship between economic viability and local management is greater than other variables. Also, the results of examining the correlation of variables show the direct relationship between local management and livability in terms of improving the situation, and the final model of the research confirms the direct relationship between local management and livability dimensions.Examining the relationship between the local management of villages around the city with different aspects of livability comprehensively and the development of tourism as a new source of employment in these human settlements is one of the innovations of the present research. The results of this research regarding the direct and meaningful relationship between rural management and the Islamic Council with livability, especially in the economic dimension, indicate that the managers' attention to the economic components of livability, such as providing the possibility of obtaining tourism jobs for young villagers, using the tourism capacities of the village, improving the level of knowledge and awareness of the residents, emphasizing the preservation of their cultural identity and effective marketing in the field of introducing the positive aspects of tourism in the village of Allahabad, such as its antiquity, proximity to the city, historical attractions and the peaceful coexistence of followers of two different religions, the level of development sustainable tourism have improved the livability index of Allahabad village and consequently it is effective in increasing the quality of life of the villagers and the desire of the young people to stay and preserve their rural identity.

Anaplasmosis, babesiosis and theileriosis is parasitic diseases that can cause significant damage to the livestock industry. Despite the importance of the pathogenicity of theileriosis, babesiosis and anaplasmosis in large animal populations, in Iran, studies have been performed mainly on small ruminants. So, the aim of this study was to the diagnosis of the frequency of Theileria, Babesia and Annapalsma infections from cattle in Alborz province using microscopic examination and PCR (Polymerase Chain Reaction). For this purpose, out of 130 dairy cattle were taken blood samples and stained with Giemsa dye. Positive smear samples were incorporated for molecular detection. DNA was extracted from blood samples with phenol-chloroform and performed PCR using 18S rRNA, 16S rRNA and TamS primers to identify of the genus and species. The results of this study showed that frequency of piroplasmic form was observed in 9.23% of cases. The 18S rRNA PCR findings revealed 5.38%, were confirmed infection with Theileria and Babesia. Also, Tams1 PCR results were indicated Theileria anulata infection in all cases. 16S rRNA PCR was detected in 3.85% for Anaplasma. No case of Babesia was observed. Considering the cases of infection with T. anulata and Babesia and the importance of some species of Babesia, the importance of further studies to evaluate these diseases in order to improve the livestock industry seems necessary.

Peppermint (Mentha x piperita L.) is one of the most important medicinal plants which used in food, pharmaceutical, perfumery, and flavoring industry.

This study was planned to investigate the effects of foliar application of salicylic acid and yeast extract on production of valuable essential oil components in peppermint.

A completely randomized design experiment with nine treatments consisting salicylic acid (40, 80, 160 and 320 mg/l), yeast extract (0.25, 0.75, 1 and 1.5 g/l) and distilled water (control) with three replications was carried out under greenhouse conditions.

In total, forty compounds were identified in the essential oils of the plant aerial parts. Menthone, menthol, piperitone, isopulegol and

γ-terpinene were the major compounds of the oils studied. Menthone and menthol were 16.69 % and 14.39 % of the essential oils, respectively. Salicylic acid and yeast extract were increased menthone, neomenthol, piperitone, γ-terpinene and isomenthol acetate production 42, 60, 39, 59 and 34 % higher than control plants, respectively. Foliar application with 320 mg/l salicylic acid gave the best result in the enhancement of the major essential oil components of treated plants. The results of correlation between essential oil constituents showed that the neomenthol content had a significant positive correlation with menthone (r = 0.865**), γ-terpinene (r = 0.848**) and negative correlation with isopulegol (r = -0.886**).

The quality of essential oil of M. piperita were influenced by the foliar application of salicylic acid and yeast extract at the appropriate concentrations. Elicitation by 320 mg/l salicylic acid was the optimum treatment for menthone, neomenthol, γ-terpinene and piperitone production.

The present study aimed to examine the roles of stress coping strategies in reducing fear of coronavirus among medical staff.

The present study was descriptive and correlational. The statistical population consisted of all staff of Ahvaz Jundishapur University of Medical Sciences in 2009-2010. The sample size was equal to 100 who were selected using the convenience sampling method. We collected data using the Coping Inventory for Stressful Situations (1990), and the Coping Inventory for Stressful Situations (1998) using SPSS (Ver. 25), Pearson correlation coefficient, and simultaneous multiple regression.

The results indicated that there was a negative and significant relationship between problem-focused coping strategy and fear of coronavirus among the staff of Ahvaz Jundishapur University of Medical Sciences (P<0.01). Furthermore, the results indicated that there was a positive and significant relationship between avoidance-oriented and emotion-oriented coping with the fear of coronavirus among the staff of Ahvaz Jundishapur University of Medical Sciences (P<0.01).

According to the results, programs can be designed to increase effective stress coping strategies and reduce the fear of coronavirus and they can be implemented through electronic and virtual training workshops to reduce the fear of coronavirus in hospital staff.

Usually sowing date and harvest time of summer crops such as maize have a significant impact on the quantitative and qualitative yield of the crop. Therefore, the aim of this study was to investigate the effect of sowing date and harvest time on quantitative traits and yield of silage maize (single cross 701; cv. Karun), this experiment was done as a split plot based on completely randomized blocks design with three replications in Varamin at year of 2015. Treatments included five sowing dates as main factor (9th of April, 21th of May, 18th of June, 30th of June and 15th of July) and two harvesting times as sub-factor (grain milky stage and grain dough stage). The results showed that the effect of sowing date had significant effect at 1% level on the stem fresh weight, maize fresh weight, total fresh weight, stem fresh weight to total fresh weight ratio, maize fresh weight to total fresh weight ratio and fresh forage yield and significant effect at 5% level on the leaf fresh weight to total fresh weight ratio. Based on the findings sowing date of 30th of June has more fresh weight of leaf, stem and ear and more fresh forage than other sowing dates. Harvesting time in milking stage has better quality and harvesting at dough stage has higher quantity of product. Correlation between studied traits showed positive and high effect of stem fresh weight with forage yield. In general, it can be stated that summer sowing dates, especially 30th of June and harvest time at the dough stage are the most favorable times for silage corn cultivation in the Varamin region.

Drought stress is a major cause of reduction in crop production. According to the role of various plant parts, especially the spike photosynthesis in grain filling and the regulatory roles of IAA in formation of grain yield, a split plot-factorial experiment based on randomized complete block design (RCBD) with three replications was conducted at the experimental field of the Campus of Agriculture and Natural Resources, University of Razi, Kermanshah, in 2010-2011 growing season using two wheat cultivars (Marvdasht and Pishtaz). Results indicated that water stress after pollination significantly decreased grain yield and 1000 grain weight but it did not affect grain no. spike-1, number of fertile and infertile spikelet per spike and spike length as compared well-watered conditions. Drought stress caused 25.7 and 22.6 percent reduction in grain yield and 1000 grain weight of varieties under study respectively. Cultivars differed in grain no. spike-1, 1000 grain weight, number of fertile and infertile spikelet per spike and spike length significantly. Water stress also reduced grain yield of Marvdasht cultivar (31.8%) as compared to Pishtaz cultivar (18.7%). Pishtaz cultivar possessed larger spikes which resulted in grain yield increase under drought stress. Photosynthesis of spike during grain filling stage increased yield under well watered condition by 42.5% and under post-anthesis drought stress by 23.8%, respectivly. Foliar application of IAA did not have any effect on yield reduction when photosynthesis was stopped. This shows the importance of spike photosynthesis in increasing grain yield.
