Abstract: 

Resistance is one of the fundamental Quranic values in the cause of the development of the Islamic society AND the formation of the Islamic civilization, which means stANDing AND resisting against something has upset the balance in internal AND external dimensions. The formation of this value in the society as one of the methods of the conventional model of human life in the fields of human life; So that its manifestation can be observed in the totality of social behaviors, it is called the culture of resistance (Problem statement). The purpose of this article is the achievement of the ENGINEERING process of this value in a society based on the growth-oriented thought (ideological) system of the Holy Quran (Purpose). Now the question is what process does the Holy Quran propose in order to engineer the culture of resistance in the society? (Question). The necessity of examining this issue is clear considering the emphasis of religious teachings on this value AND the need for Islamic societies, especially considering the current conditions of Islam AND the need for convergence AND coordination between the resistance front (Necessity). The research method in stating the ENGINEERING process AND its components is qualitative content analysis with an analogy approach (Method). The findings of the research show that the ENGINEERING process of resistance culture is based on a self-awareness AND purposefulness, according to the idea of Quranic growth, in a three-stage process that leads to the happiness of man AND human society (Conclusion).

Abstract: 

The aim of the current research was to identify the CHARACTERISTICS of the four elements in order to provide a problem-oriented curriculum model in the elementary school mathematics course. There were 19 participants AND the sampling was done purposefully. The data collection tools are semi-structured interviews AND questionnaires. The problem-oriented curriculum template was designed using the CHARACTERISTICS of the elements AND with the method of qualitative content analysis in the elementary school mathematics course. The identified features were validated by fuzzy Delphi method AND Shannon's entropy method was used for data processing. Based on the results of the analysis, 7 main categories including the CHARACTERISTICS of goals at three levels of cognitive, attitudinal, skill, content, evaluation, teaching-learning strategy AND 46 sub-categories were identified.                                                                                                                                                                In the fuzzy Delphi section, all features were confirmed by obtaining a de-fuzzified value greater than 0.7. The results of Shannon's entropy determined that the CHARACTERISTICS of starting teaching with a challenging question, creating a suitable educational environment, continuously monitoring the quality of learning strategies AND communicating with students' talents have attracted the most attention AND obtained the highest ranks AND had a higher importance factor than other CHARACTERISTICS

Abstract: 

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.

Abstract: 

To understAND the relationship between ENGINEERING CHARACTERISTICS AND PETROLOGICAL features, eight samples of the Qom Formation conglomerates from Famenin region in North-east of Hamedan of province were collected. Samples were examined in the laboratory for determining the uniaxial compressive strength, point load strength index, modulus of elasticity, porosity, dry AND saturation density. For determining the PETROLOGICAL features, textural AND mineralogical parameters, thin sections of samples were studied. In this study, based on the results of statistical analysis, predictive relationships were developed to estimate physical AND mechanical properties using PETROLOGICAL features. This study showed that the effects of texture properties on the ENGINEERING properties is more important than mineralogical composition. It also became clear that the packing proximity, packing density, grain shape, mean grain size, percentages of cement AND matrix are textural features that have a significant impact on the physical AND mechanical properties of studied conglomerates. In the present study, multiple linear regression (MLR) was used in four different steps including different combinations of PETROLOGICAL features as input variables for each ENGINEERING characteristic. Finally, the best relationships were developed to predict the ENGINEERING properties of Conglomerates.

Abstract: 

The Chaldoran area in the northwestern portion of Iran has a Mesozoic oceanic crust basement. The studied rocks of this region can be divided into three groups: ophiolitic gabbros AND pillow lavas, ophiolitic volcanoclastics AND Eocene lava flows. Ophiolitic mafic rocks exhibit a continental volcanic arc nature while Eocene lava flows are of an OIB-like nature. During the Mesozoic era, the Chaldoran region was situated in the active continental margin of the Iranian plate due to Neotetyhan subduction beneath the SSZ (SanANDaj-Sirjan Zone). As the Neo-Tethyan subduction regime changed, a rift in the Chaldoran area was generated which caused a continental back arc basin during the Upper Cretaceous period. A spreading basin in the oceanic ridge along with the creation of newly formed oceanic crust gave rise to oceanic islANDs which became active AND formed volcanoclastic rocks in the Chaldoran Oceanic crust. These were the result of ascending continental arc nature plumes that formed in the sub-oceanic crust AND extended up to the Neo-Tethys subducted slab in the mantle wedge. After the basin finished spreading in the early Paleocene, sedimentation followed continuing up to the Middle Eocene. During the Upper Eocene, alkaline AND OIB-like volcanism was active in the Chaldoran area due to the breaking off of the Neo-Tethyan subducted slab in the sub-oceanic crust of the Chaldoran area causing the development of an asthenospheric window.

Abstract: 

In this study, chemical compositions of black seed meals samples were determined. 18 male weaning ZANDi lambs with an average body weight of 23.5 ±1.5 kg were used in a completely rANDomized design in three groups of six in individual pens. Experimental treatments were: 1) control (basal diet with 12% soybean meal AND without black seed meal), 2) diet containing 6% soybean meal AND 9% black seed meal AND 3) diet containing 18% black seed meal AND without soybean meal. The concentration of dry matter, crude protein, crude fat, NDF, ADF, ADIN, AND crude ash of black seed meal samples were 97.53±0.58, 31.26±0.99, 15.16 ± 0.61, 25.95 ± 1.34, 14.2±0.80, 0.69±0.04 AND 5.07 ± 0.24, respectively. Replacement of soybean meal with black seed meal in the diet of experimental lambs had no effect on final body weight, daily weight gain, feed conversion ratio, dry matter intake, dressing percentage, tail AND total body fat deposition. Albumin AND total protein were higher for lambs fed by diet containing 18 % black seed meal compared to other treatments (P <0.05). However, the concentration of blood triglyceride, cholesterol AND urea nitrogen were not differed between experimental groups. The digestibility of dry matter, organic matter, crude fat AND protein were not affect by feeding of experimental diets. It seems that black seed meal can be used in the diet of fattening lambs up to 18% without adverse effect on performance AND nutrients digestibility of growing lambs.

Abstract: 

The Oligocene-Miocene granitic rocks of Deh Siahan, part of central Iranian volcanic belt, are intruded into Eocene volcano-sedimentary complex where their contact is marked by albite-epidote hornblende hornfels facies AND granitic apophyses. The granitic rocks show enhanced LIL element abundances AND low HFS/LIL ratios. Geochemical data, various trace element discriminant diagrams, enhanced Y/Nb AND Ce/Nb ratio, AND ocean ridge granite normalized multielement diagrams indicate that the Deh Siahan granitic rocks have CHARACTERISTICS of high-K, calc-alkaline, I-Cordilleran type granites of volcanic arc settings. In this aspect, it may represent part of an ANDean-type magmatic arc formed in response to subduction of Neotethys oceanic crust beneath Central Iran, unrelated to a rift settings. The partial melting of subducted oceanic crust led to the formation of basic magma. Its emplacement under the mantle wedge provoked melting in the considerably metasomatized AND enriched sub-continental lithosphere. This caused generation of siliceous magma which its low pressure crystal fractionation eventually led to the formation of Deh Siahan granitic rocks.

Abstract: 

Melting products AND PETROLOGICAL properties of slags are a potentially powerful tool for research about the technologies in ancient world of mining AND metallurgy. This study deals with the archaeometallurgy of copper in different region of the world specially Toroud in Iran. The interpretations are based mainly on finds from some of these areas in Iran, but include also investigation of material from other sites. The extension of studies was necessary for a better understANDing especially the techniques which were used. Several lodes of rather different mineralization were recorded in Toroud copper mine belonging to tow major types: One mainly chalcocite, carbonate AND chalcopyrites containing 6-20% copper AND only low Zn AND Pb, the other mainly blende AND galena. In view of the complexity of the latter ore lode which is rather difficult to smelt, it must be assumed that the prehistoric grooved stone mining tools were originally used for the mining of copper ore, probably from outcrops on the upper sloped of the hills of Toroud AND Chah-Musa, traces which can still be seen.The ancient field of Toroud is in the northern part of the central Iranian's big desert. Smelting sites situated mostly near the wells. The location from the mountains areas down to the plains show an increasing amount of smelting activity AND a more complex method of metal extraction. This corresponds with a significant change in smelting technology, deduced from the mineralogical AND chemical composition of the slags. The slags can be characterized by a continuous decrease in iron, whereas the quantitative relation of three other main components CaO, Al2O3, SiO2 remains largely constant. This difference in composition is primarily due to technological requirement of different extractive steps, especially at the probably younger sites in the desert plains, AND only partially due to a certain technological evolution. Slags compositions seem to start with rather high iron contents. Thus the development follows a chain from older fayalitic slags to younger fayalite-chlinopyroxen slags AND eventually chlinopyroxen-melilite slags. Actual slag compositions are usually almost eutectic. Metal extraction is based on polymetallic sulfide copper ore with varying contents of lead, zink, nickel AND arsenic. In some case iron ores from local deposits AND some calcite were used as fluxes. The slags contain a full sequence of sulfide phases AND metal from discrete liquids which form in the silicate melt. Intermediate products are mainly high temperature bornite, partially unmixing high iron sulfides AND melting copper AND iron. Partial oxidation of the matte results in metallic copper.

Abstract: 

This study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at Safi-Abad Agric. Res. Center during 2003-4 AND 2004-5. Five nitrogen rates (0, 60, 120, 180 AND 240 kgha-1) AND two monogerm sugar beet varieties (Shirin AND Rasol) were arranged as factorial in a rANDomized complete block design with four replications. There was a significant difference between years for most sugar beet yield parameters. In the first year, nitrogen had no significant effect on root yield (mean of five rates was 93 t/ha) but changed sugar content significantly. N0 had the highest sugar content (13.7%). In the second year, root yield was influenced significantly by nitrogen so that N240 produced the highest root yield (80.9 tha-1) whereas sugar content did not change significantly. There were no significant differences between two varieties for all yield parameters in the two years. Increasing N shifted allocation of biomass to petiole AND crown AND reduced its allocation to root. But no differences between nitrogen rates for biomass allocation to leaf were found. All nitrogen rates had same leaf number, leaf area index AND canopy closure during the first year, but during the second year increasing nitrogen levels accelerated canopy closure AND increased leaf number AND leaf area index. Nitrogen had no significant effect on nitrogen content AND nitrogen uptake of different plant parts in the first year. Total nitrogen uptake by sugar beet at the end of season was 574 kgha-1 in the first year. In the second year, total nitrogen uptake was influenced by application of nitrogen, so that uptakes in 0 AND 240 kgha-1 N were 186 AND 351 kgha-1 respectively.

Abstract: 

Evaluating the cutting rate (CR) of stones is important in the cost estimation AND the planning of the stone processing plants. This research used regression models to estimate the stones’ CR based on their physico-mechanical CHARACTERISTICS. Stone processing factories in Mahallat City (Markazi province, Iran) were visited, AND the CR of diamond circular saws was recorded on six different travertine stones. Next, the stone block samples were collected from the quarries for laboratory tests. Stones’ porosity (n), uniaxial compressive strength (UCS), AND Schmidt hammer hardness (SH) were determined in the laboratory as their physico-mechanical CHARACTERISTICS. Correlation relationships of CR with physico-mechanical CHARACTERISTICS were evaluated using simple AND multiple regression analyses, AND estimator models were developed. Results showed that multiple regression models are more reliable than simple regression for estimating the stones’ CR. The validity of the developed multiple regression models was verified with the published data of one researcher. The findings indicated that these models are accurate enough for estimating the CR of stones. Consequently, the multiple regression models provide practical advantages for estimating the CR AND save time AND cost during the planning AND design of the stone processing factories.
