The present paper will investigate the specific elements of architectural design based on Islamic beliefs, by taking Iranian Architectural values and vernacular climate design methods into consideration. This research will assess the spirit of experimental elements, created by the inhabitants, according to recent scientific findings. The main concentration will be on the physical design of rura...
Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA) was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human healt...
Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...
The Zouzan area is located in the SE of Torbat-e- Heydarieh city (NE Iran). This area is located on north part of the Lut block which consists of basaltic andesite, tuff and porphyritic andesite. The purpose of this research is to investigate the enrichment of metal elements in the Zouzan area and provide a metallic geochemical model. For this purpose, 488 stream samples were analyzed using by ...
Four types of edible tubercular roots cultivated in Saudi Arabia are analysed through sequential determination of certain essential and toxic trace elements by inductively coupled plasma atomic emission spectrometry (ICP-AES). Comparable runs carried out using both flame and graphite atomic absorption spectroscopy (AAS). Radish proved to contain the highest concentration level of iron (>21 μg/g...
BACKGROUND Human plasma ATP concentration is reported in many studies as roughly 1000 nmol/L. The present study tested the hypothesis that the measured plasma ATP concentration is lower if ATP release from formed blood elements is inhibited during blood sample processing. A second hypothesis was that pretreatment with aspirin to inhibit platelets would reduce the measured plasma concentration o...
soil genesis and evolution studies are based on well understanding of geochemical processes involved in pedogenic processes and formation of soil. parent materials are main factors controlling soil properties in arid and semiarid regions. in this study, physicochemical and geochemical properties of 6 selected soil profiles developed on basalt rocks along arid (eshtehard), semiarid (qazvin) and ...

Pottery is as the most abundant material data in the archaeology. Archaeologists have studied pottery from a different point of view, such as typology, stratigraphic situation and relevance, but less attention has been paid to pottery figures. Elements of aesthetical and harmonic such as repetition, symmetry, balance, proportion, concentration and etc are frequently seen on the prehistoric pott...
This paper delineates the development of a computer system designed to automatically rate elements of art assessment in structured mandala, provide the results in the form of quantitative data, and thus facilitate the decision making process of human experts. Based on the analysis of the color-related basic elements by computerized digital image processing, the system deduces information on the...
