The aim of this study was to investigate the effect of using portulaca oleracea as a source of plant antioxidants for feeding fattening male lambs, on carcass traits, meat quality, and oxidative stability. Twenty-one male lambs with an average weight of 24±1.5 kg and 150±15 days old were fed with one of the experimental rations included a diet without portulaca oleracea as control, a diet containing 7.5%, and a diet containing 15% portulaca oleracea, for 84 days. The muscle (Longissimus dorsi) samplewas used to determine pH, chemical COMPOSITION, colorimetric properties, and oxidative stability of meat. Meat lipid oxidation was determined after 1, 7, and 30 days of refrigerated storage using thiobarbituric acid (TBARS). The use of portulaca oleracea in diets improved meat color characteristics such as L, chroma, and Hue. The highest ash concentration and the lowest meat moisture were observed in the treatment of 15% portulaca oleracea (P<0.05). Meat pH was the lowest in the first hour after slaughter but did not differ at 24 h. Compared to the control, in both treatment groups feeding the lambs with portulaca significantly reduced the concentration of Malondialdehyde in the meat of the lambs and increased the meat oxidative stability (P<0.05). The results of this experiment showed that feeding portulaca oleracea by improving properties such as color and increasing the meat oxidative stability improves meat quality, which may have lead to an increase in its nutritional value in terms of human health.

This study has been done to investigate crab funa of sub tidal regions in Gulf of Oman,  2010. To this purpose, a stern trawles, 56 stations from Hormoz strait to Meydani area were designated. Localities in thirteen species belonging to eight genera from seven families were identified. The most frequent family was Portunidae with 56% and high commercial value, and the least frequency observed by Calappidae and Parthenopidae with 2%.

In some point of view, neither Michel Foucault nor Ibn Khaldun are considered philosophers in the conventional classifications, but both are very  important in intellectual and, of course, in philosophical contexts, especially for those who are interested in the deep study of human life from the perspective of political thought.The main concern of two thinkers, one in the 14th century, the other in the 20th century, is the issue  of power, although neither of them provided a precise definition of it. In this article, an attempt has been made to show the place of power and domination in the political thought of both thinkers by examining the thoughts of two thinkers. And in search of an answer to this question, how did Asabiyyah and industry of religion in Ibn Khaldun's thought and social control through self-technology and discipline in Foucault's thought lead to the expansion of the domination of power? This article is written by analytically comparing the opinions of two thinkers based on Ibn Khaldun's most important book called Muqaddimah and Foucault's late works

This project was carried out with the aim of making a suitable net (mesh size, 1mm; total length of filtration area, 143.3cm including cylindrical and conical parts; and bucket volume, 1.7 liter) for CATCHING M leidyi with the least injury, having efficient filtration and the most catch.For comparing it with plankton nets, some samplings were carried out in the two length groups 4-9mm and 12-25mm at depths of6 and 12m at 1m/s speed. Result revealed no significant difference between percentage of intact and injured samples of two nets in 4-9mm length group (P>0.05), whilst in 12-25mm length group, intact sample percentage in the experimental net was more than conventional plankton net (P<0.05). Some samplings were also done at depth of 12m at 1 and 1.5m/s speeds by the experimental net in order to find the suitable speed of towing. Result showed significant difference between the number of injured samples at two mentioned speeds (P<0.05) and the suitable speed of towing net for CATCHING of this animal was obtained at 1m/s. Filtration efficiency at speed of 1m/s was and at speed of 1.5m/s was 0.95.

Natural light has been an important element in Iranian architecture and shaped interior spaces of monuments.During different historical periods, the presence of light in various Architectural works, have always been under focus from spiritual religious aspects in addition to the functional aspect. The incentive towards light direction during worship has existed in different religions and still exists. Daylight has always had a special place and value in Islam and the Islamic worldview. With emerge of Islam, usage and application of light in architecture increased especially in mosques as the most important monuments of Islamic architecture.Daylight, in addition to functional aspect, is considered as a mystical symbol and a sign of God's presence in the mosques, which raises the human sense of reverence and humility in front of God. To this end, for centuries, Iranian architects have been trying to use traditional architectural elements and day lighting solutions to improve the deployment of natural light in their designs.This study attempts to investigate and evaluate the application of light-CATCHING elements in Iranian mosques, particularly in mosques and mosque-schools from Qajar period. We use a descriptive and analytical research method and our study is mainly on the basis of resources and the literature available in Iranian libraries. After describing the theoretical foundations of our research, we analyse a number of common light-CATCHING elements through research’s selected mosques. Although a multitude number of studies have been done on the concepts of light and its role and function in the traditional architectural monuments, particularly mosques and homes, little study has been done on light-CATCHING elements in mosques of a specific period as done in this research.Structural elements which have been used in Iranian traditional architecture for utilization of daylight are studied from two directions. In the first direction, light-CATCHING elements often have the task of transmitting light into the interior space. In the second direction, light controlling elements adjust the entered light through the building (similar to canopies). The subject of this research is in line with the first direction. We only study light-CATCHING elements and we chose thei common elements such as door and window, Shabak, Horno, Rozan and Roshandan. Although these elements are different in term of material, type and location of application in the building, all of them are used for light-CATCHING even though some of them are also containing ventilation application. We chose 10 mosques and mosque-schools of Qajar period in Tehran. The examined mosques and mosque-schools in this research were selected based on the following criteria: first, all the selected mosques and mosque-schools are located in old and valuable regionof the city and they are tourist attraction. They have architectural values and are well-known among people and experts. Secondly, the buildings of selected samples reflect prominent features of Qajar’s architecture.Also the sufficient information (including maps and images) are available for these monuments. We chose 5 mosques and 5 mosque-schools among Qajar’s architectural works. Then, the usage and the application rate of light-CATCHING elements in these buildings are evaluated quantitatively and qualitatively by the use of maps and the available visual data. Quantitative analysis is based on the approximate numbers of elements used in these mosques which have been extracted from the available images and maps. To qualitatively evaluate the application rate of various methods of light-CATCHING in these mosques, we specify four levels of usage: "insignificant", "low", "medium" and "high". We provide the results of quantitative as well as qualitative analysis in this paper.Our analytical studies indicate that although door and window, Shabak, Horno, Rozan and Roshandan had been considered as innovative lighting elements inside mosques of Qajar period, architectures of this period still mainly used door and windows as the main lighting elements. Next to doors and windows, Rozan stands at the second place, Horno in the third place, and then Shabak and Roshandan. The utilization rate of doors and windows among considered mosques and mosque-chools has been similar. Nevertheless, the usage of Horno as a lighting element in mosques has been more than mosque-chools. Rozan and Shabak have yet been used more in mosque-chools rather than mosques. Roshandan has been barely used in the mosque schools, and only few samples could be found within some mosques of this period.
