Thermal performance analysis of a traditional passive cooling system in Dezful, Iran

This paper presents a case study research to analyze thermal performance of a type of Iranian underground living space, called Shavadan. Shavadan is part of building typology in the city of Dezful, southeast of Iran. The focus of the study is to introduce a passive design structure to further demonstration of the significance of the thermal performance analysis of Shavadan and the design effectiveness. Shavadan design structure, the main strategy of architects and building construction practitioners in the past, plays an important role to increase the indoor thermal comfort of buildings in hot and humid climates. Shavadans were built underneath houses, schools, mosques and public spaces at depths of 6–10 m, where the thermal behavior of the earth is almost stable. But this approach is totally forgotten in today’s buildings and people do not know how to use it, even if they desire to. Based on a measuring ambient air temperatures, in this paper the thermal behavior of five settings in different parts of Dezful is studied, from June to December. Moreover, the temperature stabilities of various Shavadans were compared to evaluate the architectural effectiveness of Shavadans in terms of the complex passive systems. The results show that it is useful to consider passive strategy as an auxiliary system to reduce domestic energy use in hot semi-humid climates where there is considerable electricity demand for air conditioning in the over 40°-Celsius-heat of these zones.

Antibacterial and anticancer activity of a bioflavonoid fractionated from Allium Ascalonicum

Allium ascalonicum is a part of the diet of many populations of the world due to their long-held beliefs. A. ascalonicum extracts have been reported have antibacterial properties and prevent cancer cell proliferation. This study was conducted for the purpse of evaluating the anticancer and antibacterial activity of a flavonoid fraction isolated from A. ascalonicum bulbs. The HeLa and HUVEC cells were used as target cell line and some gram negative and positive bacteria were also targeted for antimicrobial activity. The A. ascalonicum plant was collected from the Zagros Mountains in the north of Dezful city- Iran, in September 2016 and confirmed by School of Pharmacy, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran. The water extract of bulbs of this plant was extracted and the flavonoid fraction was isolated from aquous extract by ethyl acetate. The antibacterial and anticancer effects of isolated falavonoid were determined using MIC and MTT respectively. The best antibacterial effect of falvonoid extracted from A.ascalonicum was found against C. diphtheria . Furthermore, gentamicin resistant P.aeruginosa was the most resistant pathogenic bacterium. The MTT method showed that this fraction had a concentration-dependent anti-proliferative activity on HeLa cell lines and there was no cytotoxic effect against HUVEC cells. The inhibitory concentration 50% (IC50) values of the A. ascalonicum extract for Hela cell was 3 mg/mL but the treatment of HUVECs with the A. ascalonicum showed no considerable effect. The flavonoid fraction of A.ascalonicum bulbs had remarkable antibacterial and anticancer properties. Therefore, it could be used as an antibacterial and anticancer agent for control of cancers and infectious diseases.

SPIRAL PARABOLIC DOME: HISTORICAL STUDIES OF IRANIAN ARCHITECTURE

Ancient Dezful city is located in the SW of Iran (5000BC-2016AC) near Dez River. This spiral domes are used to demonstrate the symbolic special constructions which is similar to the construction of Denial’s holy shrine, the Jewish messenger (500BC), the Lion King Yaghob Saffari’s tomb (800AD) and the Rood-band Syd’s burial place (1409AD). These structures are made by simple local materials. The common materials used are bricks and Sarooj mixture. Sarooj is the main mortar, a man-made concrete. After thousands of years, it still stands all kinds of tension, pressure, wind, rain, conflicts and wars, weapons and rockets effects (1980-1988), and sewage exposure. All bricks were set to demonstrate the cubic elements around the spiral curve. It turns around circles with variable radiuses on the spiral path-line which makes a conic parabolic sharp dome. Two domes constructed in each parabolic dome. The first dome is fixed between the supports that are called the inner dome. It was erected on the semi sphere space. The second dome is constructed by the parabolic conic section to demonstrate a beautiful, cultural and architectural masterpiece of engineering. The Main materials are bricks, dolomite, canes, stone blocks and Sarooj, a special mortar. The height of the Spiral Parabolic Dome (SPD) is about 10m and the radius of the inner dome is measured about 2 m with a ratio of 2.5 that would vary with the Geo-technical conditions and the architectural considerations.

Evaluation of river–aquifer interaction in the north part of Dezful–Andimeshk district, SW of Iran

The river and groundwater are significant components of hydrological cycle, and the interaction between these two water resources attracted a great attention recently. Over the years, several methods have been used for the study of the water exchanges between these resources. In this research, a combined approach including hydraulic head measurements, hydrochemistry, and water balance calculations is applied to the assessment of the river–aquifer interactions. The study area is located in the north part of the Dezful–Andimeshk district in the southwest of Iran. The Dez River is the major surface water body that interacts with groundwater in this area. The Dez dam has been constructed on this river in the northern part of the study area. In this study, a series of water measurements including river water stages and discharge monitoring at Dez dam site and Dezful hydrometric station, groundwater table measurement in the piezometric network, and chemical analysis of river and groundwater were carried out for the evaluation of river–aquifer interaction. In order to monitor river and groundwater in the study area, a monitoring network including a hydrometric station (near the Dezful city), 38 piezometers, and 23 water quality monitoring wells have been established by the Khuzestan Water and Power Authority (KWPA). Data of the monitoring network were used for the evaluation of temporal variation of river and groundwater interaction in this research. The discharge measurements of the Dez dam site and Dezful hydrometric station in a 47-year period (1964–2011) shows that the water volume is decreased between these two stations. In addition, examining the time series of river stage and groundwater fluctuations in the study area shows that the groundwater table and river water stage variations have similar patterns. This similar pattern is an observant indication of groundwater and surface water interactions that is confirmed by the interpretation of groundwater potentiometric map of the study area. Following these conclusions, the hydrochemical measurements also were used for the assessment of the Dez River and groundwater connectivity. The surveys showed the similar patterns in the temporal variation trends of chemical characteristics (especially chloride ion) of the Dez River and groundwater as a base for connectivity of these resources. For better assessment of the river–aquifer interaction, 69 groundwater samples were collected from the abstraction wells in August 2012. The physicochemical analysis results show the river influences the groundwater quality. That is, the amounts of electrical conductivity (EC), temperature, and anions such as chloride, sulfate, and nitrate show a notable decrease in river-adjacent wells. Finally, for the quantifying of river–aquifer exchange rate, a simple water balance was formulated. This water budget also confirmed the Dez River role in the hydrologic balance of the study area, and according to calculation, the water infiltration from the riverbed was estimated to be more than 8 % of the aquifer recharge. This research shows the losing nature of the Dez River and its influence on the underlying groundwater quality in the study area.
