Groundwater is the only vital source of water for millions of people around the world and its contamination has dire impacts on human health, industrial activities, agriculture, and the environment. The drinking water in the City of Qom is supplied from neighboring water basins transferred by interbasin water transimission facilities and from water wells within the city. The growing demands and the consequent increasing water scarcity have augmented and foregrounded the significant role played by the water wells in this city. Nitrate as a widespread pollutant originates from human activities and the dumped wastes that lead to the gradual degradation of groundwater resources, which might go undetected for years. On the other hand, remediation of polluted aquifers is a formidable, cost-intensive, and, at times, impossible endeavor. In this study, groundwater resources in the city of Qom were investigated in terms of their nitrate concentration. For this purpose, 600 groundwater samples collected from 2006 to 2013 by the Qom Water and Sewage Company were used, 136 of which were found to be polluted with nitrate. In order to validate the data thus obtained and to identify the contaminated areas, additional samples were collected from 27 wells in December 2013 and subjected to the relevant analysis. The latter analysis revealed a mean nitrate concentration of 74 mg/L and a standard deviation of 37 mg/L, with nitrate contamination detected in 19 wells accounting for 70% of the sampling sites. Generally, the results indicate that the aquifers within the city of Qom suffer from nitrate contamination.

Mental disorders are prevalent worldwide, and can expose people to significant harm. Diet plays an important role in the development and progression of mental illness. Thus, possible associations were investigated between major dietary patterns and depression, anxiety and stress in adults. This cross-sectional study was conducted on a random sample of adult participants (n=265) in Tehran. Anthropometric characteristics were measured, and physical activity was assessed using a short-form physical activity questionnaire (IPAQ). Dietary patterns were determined using factor analysis on 25 food groups using a valid, reliable, 147-item semi-quantitative food frequency questionnaire (FFQ). The dietary patterns were analyzed by factor analysis (PCA) method. Blood samples were taken for measurement of blood parameters. Data about depression, anxiety and stress were collected using the Depression Anxiety Stress Score (DASS-21). The unhealthy and healthy dietary patterns were extracted. The findings showed that higher adherence to a healthy dietary pattern led to a reduction in the mean depression score (P = 0.03). There were no statistically significant differences between the unhealthy dietary pattern and depression, anxiety and stress scores. In logistic regression models, after adjusting for potential confounders, the results showed that higher adherence to the healthy dietary pattern led to a reduction in anxiety odds ratio (OR) (P = 0.03). There was no statistically significant association between the major dietary patterns with the risk of depression and stress in the crude and adjusted models. The findings from this study indicate that adherence to a healthy dietary pattern led to a reduction in mean depression score and anxiety OR.

Mosque is one of the most important Muslims' buildings and one of the best expressions of Islamic community (Ummah). In spite of considerable architectural history of the mosque in Islam and Iran, it seems that there are significant questions about the ideal mosque in Islam. For example "open space" (or courtyard), regarding its undeniable importance according to Islamic tradition (Sirrah & Sunnah) and architectural history of the mosque, has being weakened. The open space in mosque which not only improves the quality of architecture but also worshiping within has a special significance. Neglecting this importance has led to gradually reducing or even eliminating the open space in the mosques. In this regard, a combined style was choose to examine the originality of open space, using historical interpretation and content analysis methods about the main references of Islam (the Quran, Hadith and life of Prophet (PBUH)). Therefore, the original mosques of centers of Islamic territory from the beginning of Islam to the sixteenth century and also mosques without open space were reviewed. Then Masjid an-Nabawi considering the approach of the Prophet (PBUH) about its architecture and Masjid al-haram were added to the analysis.

Despite of common categorizing of mosques based on closed spaces, the masjid An-Nabawi which had been built by supervising of the last Prophet (PBUH) hadn’t any closed space. Considering the hard climatic requirements, available roof construction technics and user requests (based on historical texts), prophet's decision to not making a hard roof is a major reason of priority of open space in mosque. Masjid al-haram as an ancient religious Islamic site and one of the most symbolic aspects of Islam has always been in open space and even hadn’t had roof itself during thousands years.

 There are also many prayers and Islamic rites which should be - or is better to - done under sky, especially not personal ones like Hajj, Fitr Salah, Qorban Salah. This could be remarked as a presentation of public aspect of worship in Islam in contrary of the isolation in some other religions (e.g. Christianity, Judaism and Buddhism). It is more impressive by attention to mosque's major function: daily congregational prayer (Salaat Al-Jamaah). Also there is some Islamic advises about not making roofed mosque. The important point about these sentences is removing any obligation about building mosques with or without roof which could cause many difficulties. But it doesn’t mean there is a neutral viewpoint. Advises is showing the priority of open space to closed spaces.

Regarding the pattern of masjid An-Nabawi, open space is always noticeable part of architectural history of mosque, especially in major mosques of main centers of Islamic territory during more than fourteen hundreds years. It could be more significant by attention to their various climatic, cultural, architectural, historical, technical differences in a vast geography and long time period. It could be led us to re-categorize mosques not only based on closed space but also caring open space changes. There are also many evidences showing mosque yards as a place for saying prayer and worship.

The most opposite point of the importance of open space in mosques are some mosques without open space. These mosques which are totally closed space might be referenced as contravention to open space based mosques. In analyzing these samples two points must be considered: first is the flexibility of Islamic sentences especially in form design and Islamic accommodation with local properties. Second is capacity of these mosques to be referenced via masjid An-Nabawi. However by studding about these samples we could categorizing them in three: first are very little mosques which usually are consist of one or two rooms and direct access from outdoor in which preparing open space isn’t possible. These are neighborhood chapels that could be developing into mosques in future. Second are large mosques that are transformed from churches or other religion's temples e.g. Hagia Sophia & Al-Aghsa. These types usually conserve their structural and architectural specifications but there are examples which open space had been attached to them e.g. Yazd-Khast and Jame-Neireez. Third are special ones which had been built for specific purposes or particular condition such as Sheikh-Lotf-Allah mosque. These ones couldn’t be referenced as major movement in mosque design.

By analyzing these evidences, it is obvious that open space shouldn’t be neglected or reduced to a division junction and light-supplying space. It is a heritage and beyond; one of the major parts of mosque. Imagining the closed space as main space of worships in mosque can cause many problems such as costly construction, time-consuming build programs, circulation and space access difficulties, ventilation and light-gaining challenges and isolation effects on users.

As result, the collected evidences show not only open space in the mosque is a section or basic part of mosque, but also open space has originality in the mosque design and the worship within is a forgotten aspect of this fundamental part.

Mean platelet volume (MPV) is associated with platelet reactivity. Large platelets contain more thrombogenic factors than small ones. Previous studies have shown platelet reactivity in patients with pulmonary thromboembolism (PTE).The aim of this study was to investigate the mean platelet volume (MPV) and platelet count in patients with PTE and healthy control subjects.

In This study, 210 patients with PTE were retrospectively evaluated. The diagnosis of PTE was made clinically and was confirmed with CT angiography. 210 healthy subjects matched for age, gender and body mass index (BMI) served as control group. We recorded the main demographic, clinical and laboratory data of groups. MPV values and platelet counts were measured at the first day of admission.

Mean age between PTE patient and control group was 52.6 ± 19.7 vs. 49.43 ± 20.68 years respectively (p=0.109). MPV was significantly higher among patients with PTE in comparison with control group (10.57 ± 1.08 vs. 9.80 ± 0.86 fL respectively; p= 0.000). Platelet count was not significantly different in PTE patients and control group (231.76 ± 92.22 vs. 243.76 ± 67.32 × 10 9 /L, respectively; p= 0.129).

MPV is a simple and easy test and it can be used as an activity marker of platelet function in PTE. It also shows the platelet production rate and stimulation. We have shown that MPV was increased in patients with PTE. Platelet count was not different between PTE patients and control group.
