Hydrodynamic factors have been proved to effectively influence the high-performance heap leaching, hence this study evaluates them on column bioleaching of low grade uranium ore. Response surface methodology (RSM) was applied to predict the behavior of effective parameters particle size, irrigation rate, aeration rate and their interactions in the bioleaching process. Obtained results showed that the best model for the recovery of each metal was the quadratic model. The maximum values of uranium recovery at the optimum condition, (d₈₀ 5, mm particle size, 0.34, l/m²/min irrigation rate, and 210, l/m³/min aeration rate), were 63.85%. The results from the model and the experimental data show good agreement.

Every language and dialect uses certain styles for emphasizing, and fixing meanings in the minds and thoughts of the audience. Among these languages, and indeed the best of them is the language of the Qur'an, which has in many ways an emphasis for strengthening the concepts in the minds of its audience. Given the importance of this element in the Quran, this study has attempted to review the emphasis particles in three Quran translations methods: Literally translation, loyal translation, and commentary translation.
In this article, the authors firstly describe the emphatic particles in Quran, and then study and review (إنّInna, أنّAnna, نون التؤکید noon of emphasis)
among the contemporary Persian translations of the Quran. The study findings indicate that the literal translations of Quran surpass other types of translation in conveying the preciseand original meaning of emphasis to the target language.

Based on the theories of René Wellek and Henry Remak, interdisciplinary studies, as a sub-category of Comparative Literature, started to grow since 1980’s. The study of the relationship between literature and such arts as literature and painting has, since then, attracted the interest of many researchers. This paper is as attempt the relationship between poetry and painting through the poetry and paintings of Sohrob Sepehri. What have been discussed in this interdisciplinary research are the concepts of stasis and dynamism, which appear differently in the written language of poetry and the visual medium of painting. Though the main emphasis of this research is on interdisciplinarity, it still offers new perspective to a better understanding of Sepehri's poetry and paintings. The writers have tried to open the way for further interdisciplinary research in the field of Comparative Literature by elucidating a clear theoretical framework and research methodology.

I examine the characteristics and justifications of rational disagreement in science. It explores the relationship between the justification of rational disagreement in science and the justification of rational disagreement in the epistemology of disagreement, specifically religious disagreement. In this regard, I focus on the views of two famous philosophers of science from the second half of the 20th century, namely Thomas Kuhn and Paul Feyerabend. The views of these two philosophers on rational disagreement in science can be seen as significant, concrete, and tangible examples of the main approaches in the epistemology of (religious) disagreement, in which rational religious disagreement is justified. I bring together insights from both epistemology and philosophy of science and show reflection on disagreement in science can improve our intuitive understanding of rational disagreement in epistemology. To better understand the existing approaches in epistemology, I utilize intuitive ideas found in rational disagreement in science.

  The most important concerns of every government in order to achieve social justice and development are to get rid of the social problems caused by poverty, illiteracy and unemployment,and to fulfill the economic, social and cultural needs of people to establish security and social justice. Therefore, it is forced to adapt appropriate policies for the allocation of resources and facilities available to different economic, educational, therapeutic and recreational sectors. To implement this issue, determining priority and the advantage of different sectors is the first step to be taken in order to allocate optimum sources and facilities. Obviously,with out social classification, planning for development would not be possible. One way to achieve the development of scientific classification is taxonomy. The main concern of this paper is to show the implementation of taxonomy method and advantages of this method for ranking different sectors, and, moreover, to explain how to determine the priority of each sector. This study is descriptive and the methodology used in ofthe document using secondary sources.

Research subject: Superabsorbents are hydrophilic hydrogels that can accommodate large amounts of water in their three-dimensional structures and have wide applications in various sciences such as pharmaceuticals, medicine, and agriculture. These materials are hydrophilic polymers that are physically or chemically cross-linked. Conversion and swelling ratio of synthesized hydrogels are two counter effects. Therefore, determining the appropriate conditions for polymerization to achieve optimal properties and swelling rate of hydrogels is a challenge for researchers.
Research approach: In this study, optimizing the synthesis conditions of semi-interpenetrating poly (acrylic acid)/xanthan hydrogels, the response surface methodology (RSM) was used by Box-Behnken design (BBD). The variables of this method were the molar ratio of the cross-linking agent (X₁), the weight percentage of xanthan gum (X₂) as the reaction medium, and the amount of initiator (X₃), each of which was considered at three levels. The evaluated responses in RSM were the rate of polymerization conversion (Y₁) and the rate of swelling (Y₂) of the hydrogels in the water.
 
Main results: Based on the 17 experiments proposed by RSM (BBD), the cross-linker, xanthan gum, and initiator were combined and radical polymerization was performed into silicone molds at 65 ° C. The results of ANOVA analysis showed that the data error of this study was small and the coefficient of determination (R2) of both proposed models for the responses Y₁ and Y₂ was higher than 0.9. The 46 experiments proposed for the optimal point by RSM (BBD) with the desirability of more than 50% indicate the synthesis of hydrogels that have both a good conversion rate and an optimal amount of swelling. For example, by 13% of cross-linking agent, 0.043 g of initiator and 1% wt. the solution of xanthan, hydrogels with a 95% conversion rate, and 102% water uptake were prepared. These hydrogels can be used in a variety of fields, including the treatment of colored wastes in factories, agriculture, pharmaceutical systems, medical attractions, and more.

Lovastatin is a potent agent for lowering cholesterol of blood. Since one of the main reasons of mortality in developing countries is cardiovascular disease, which is caused by precipitation of fatty acid (especially cholesterol) in blood vessels; therefore diets containing lovastatin may prevent this type of disease. In this study, Lovastatin, monacolin K or competitive inhibitor of the HMG-CoA reductase (operative enzyme for cholesterol synthesis) was produced by submerged fermentation using Monascus purpureus PTCC5303. Seven chemical and nutritional parameters including maltose, peptone, MgSO4.7H2O, MnSO4.H2O, KH2PO4, thiamin and pH screened using Plackett Burman experimental design for monacolin production. Among different parameters, maltose and MgSO4.7H2O showed significant effect on biomass and monacolin production. The concentration of these agents were optimized using response surface methodology for lovastatin production in the shaker flask. The optimized medium contained 26 g/L maltose, 5 g/L peptone, 0.1 g/L MgSO4.7H2O, MnSO4.H2O 0.5 g/L, 4 g/L KH2PO4, Vitamin B1 0.1 g/L and pH 7. After 10 days of fermentation in the shaker flask with 130 rpm agitation and 30 ºC, we achieved maximum lovastatin production which was 63 mg/l.

ntroduction
Attracting the participation of elites to the planning discourse is one of the topics that can lead to specialized contemplation to provide a participatory model and to explain a suitable climate model for the country. In this regard, basic spatial planning against conventional spatial planning is among the frameworks and concepts that always require discursive analysis to evolve into a final model. The purpose of this paper is to propose a discussion through the context of discursive thinking and analysis about the distinctions, differences and similarities of basic planning versus conventional planning. It seems that the discursive analysis, in addition to explaining the different dimensions of basic planning can be more useful.
Main concepts of conventional spatial planning and basic spatial planning
The earliest concept of spatial planning is related to the classical triangle, whose outline is formed from environment, human and activity. In the classical approach, the most important issue that is considered is the structure or organization of space that depicts how to structure the elements of space in relation to the land area. The second view that can be proposed after the first is the concept of spatial sustainability. In this view, the main goal is to create a balance in the geographic space that provides sustainability, i.e. exploitation or lack of coordination in the relations of habitat, human and activity do not cause the balance in the geographic space. The third view refers to spatial planning, whose main purpose is to create a balance in geographic space, so that balanced development can be formed in the place of geographic space, and that it is not part of development and part of underdevelopment.
In contrast, basic spatial  planning is not only based on the same  framework of land use, but also covers national values in the macro approach. The Islamic and Iranian spirit is of particular interest in basic spatial planning. Formation of land justice is one of the important issues that has a fundamental value in basic spatial planning and its overall goal is to distribute the spatial justice facilities in the country that can create spatial equilibrium in the land area. Considering the characteristics of the land has a special role in presenting the planning policies in different scales in basic spatial planning.
Differences between conventional versus basic spatial planning
The most important distinction between conventional and basic spatial planning is that this model has been changed in terms of capabilities and facilities, weaknesses, threats and opportunities. Therefore, the most important distinction of this pattern is in importing the values of the Islamic ruler on the one hand and the territorial characteristics on the other hand. Thus, the same aspect of differentiation that is considered for the model of progress against the development model is also significant in the model of basic spatial planning against conventional spatial planning. Considering this issue, it is necessary to study Islamic ideas derived from Islamic teachings to extract the viewpoints in land use of human being, activity and space and based on them the basic spatial planning takes practical form. Considering that the views in the Islamic values are very different, using different views in the form of discursive analysis will be very effective that while examining and critiquing different viewpoints, we can achieve the best viewpoint in this regard and consider it in the final model.
Spatial planning is an empirical knowledge and a function of the geographical and cultural system of nations, and land as a spatial container is formed based on the value differences of societies and finally spatial identity is one of the most important dimensions of basic spatial planning that is not considered in conventional spatial planning as it should be. In general, the differences between conventional and basic planning can be considered in the following cases: considering human and society in conventional land and basic spatial planning has a great difference. It seems that basic human with Islamic viewpoint seeks to create a monotheistic society based on equality, and for this reason, such a human being in regulating his relationship with the environment will observe various aspects to provide the appropriate and optimal utilization of the facilities at his disposal, the grounds for human evolution and promotion of moral practice. Discursive analysis can also be very useful in this regard, because by examining the concepts extracted from Islamic values and terrestrial features, different conditions can be assessed, and their differences extracted and if necessary, provide conditions that can be presented the best model through consensus.
Similarities between conventional versus basic spatial planning
It can be said that in 80% of the cases, these two planning have a methodological and conceptual commonality. This subscription can be proposed in a variety of cases, including: the type of data required by environmental, economic, social and etc., method of collecting required data, data integration method, developing strategies, monitoring methods.
Conclusions
Basic spatial planning is a new concept that has been proposed and consequently has raised a lot of questions for the scientific community, practitioners and even the general public, which requires settlements. Discursive analysis is an appropriate tool for this subject that can help to clarify the different aspects of the subject. Preparing the context of this discourse is possible in different ways; publishing the basic concepts of fundamental planning in mass media and various social networks is one of the primary solutions in this regard. Holding various specialized conferences and meetings in academic spaces where all thinkers can present their views is also important in this regard.

Most of the Persian literary studies investigate one or more text. But in these researches, the problem of selecting the text has usually been neglected. The text, as only a material of the study, and its selecting by author usually is considered without any communication with methodological aspects. However seriously and problematic study in this subject can enhance the research aspects of the investigation. In This article, we are aimed to evaluate the importance of selecting the text as a methodological element instead of the other criteria in the Persian literary researches. It seems that attention to the text as a methodological element is related to researcher’s awareness of the relationship between the selected text and other texts, and their differences and similarities. Indicating the importance of researcher’s information and his assumptions, this view emphasis on the function of the text ant it’s selecting in the results of the study

Endoglucanase Cel9A from Alicyclobacillus acidocaldarius (AaCel9A), a thermophile enzyme, randomly breaks β1-4 glycosidic bond between glucose units in cellulose polymer and produces oligosaccharides with reducing end. In this study, first of all, E.coli BL21 cells were transformed by pDEST17 carrying AaCel9A enzyme gene for expression of the recombinant enzyme. After expression, the recombinant enzyme was purified by Ni-NTA affinity chromatography column and the purity of the recombinant protein was analyzed by SDS-PAGE. Due to impact of the calcium, pH and temperature on AaCel9A activity, the effects of these parameters were investigated on AaCel9A activity to optimize activity condition by using Response surface methodology. The SDS-PAGE result showed that AaCel9A, with molecular weight of 59 kDa, was expressed and purified. Response surface methodology data reveal that the effect of pH on the activity of the enzyme is higher than temperature and the calcium effect is less than temperature. Results showed that the optimum condition of AaCel9A activity reaches at pH 6.35 and 64.5 ˚C as well as 4.92 mM of calcium. Finally, the high correlation between experimental and predicted date indicated that the proposed model for optimizing the enzyme activity has a high accuracy.

The capital market is a bridge that transfers the savings of economic units with excess resources to investment units that need them. Using the capital market to finance the government expenses is among the most common form of financial transactions. Therefore the capital market is considered one of the major players of financing in the economy of any country. Iran’s capital market began its rapid development process in 2005 and within the past decade many financial institutes were formed by financing from the aforesaid market. Due to being new in Iran, the relation between the diverse and scattered components of the capital market has not been provided as a comprehensive model. The purpose of the present study is to investigate the structure and identify the aspects of financing services through Iran’s capital market that due to dynamic complexities of the issue (numerous players and interested parties, diverse and multiple aspects of services and conflict of interests between interested parties), soft systems methodology was used to study the current status. Therefore, in addition to performing triple analyses of cultural analysis and illustrating the rich picture of the current status, CATWOE analysis and root definition by holding numerous sessions with the interested parties were extracted that demonstrates how the financing process must be by including real world conditions. Results indicate that to improve the issue, changes in financing services processes must be implemented that emphasis on identifying and analyzing factors of market attraction, regulatory bodies and status of laws and regulations.

Sustainable competitive advantage is crucial for organizations to survive in modern competitive environment. Since competitive advantage based on creativity is one of the most crucial factors for the survival of current organizations, factors influencing organizational creativity processes should be considered at organizational decision-making level. As many people and factors are involved in organizational creativity, decision-making becomes complex and unstructured real world issues with chaotic systems behavior, and consequently, hard operation research methods are not able to represent and solve it properly.  Soft system methodology is one operation research’s methods applied to represent, structure and solve complex problems. Therefore, in this study, which is part of a PhD thesis, in addition to explaining the soft system methodology’s steps, we describe how the first four stages of the Checkland soft system methodology were applied to represent and structure the sustainable organizational creativity problem in detail. The conceptual model was created based on information gathered from experts and specialists in organized meetings and in-depth interviews who were exposed to data previously collected in reviewing individual, group and organizational creativity existing research results. At the end of these meetings and interviews we designed and developed a rich picture, root definitions, CATWOE analysis and the conceptual model for organizational creativity.

Production of recombinant proteins in Escherichia coli has been very common in recent decades. Many studies and experiments have been done in order to optimize the production and expression of recombinant proteins in E.coli. One strategy is using high cell density to increase recombinant protein production such as β-NGF in the cell. Therefore, in this study for the first time bacterial cell culture in high cell density was done using glycerol and yeast extract as carbon and nitrogen sources and MgCl2 as a growth effective factor. Also the effects of overnight culture conditions on bacterial growth were evaluated. Meanwhile culture conditions were optimized using response surface methodology (RSM) and the optimum conditions were as follows: 18/23 g/lit glycerol, 14.44 g/lit yeast extract and 10mM MgCl2. Also the obtained results indicated that the 14 hours incubation at 37 °C and 180 rpm were optimum conditions for the overnight culture. Our results showed that the rate of cell growth and recombinant β-NGF production in optimized condition is significantly higher than in basic medium.

One of the steps of a research is hypothesizing that have been argued about its necessity and method in humanities. With investigating literary studies, it may be said that hypotheses haven’t any function in the research process. Critiquing the position and concept of hypotheses in literary researches, in this paper, we trace answers to these questions: why don’t hypotheses have any function in solving literary problems? Can we define a type of the hypotheses for these studies? There is a methodological difference between the concept of literary theory and theory in empirical methods. This different cause hypothesis in literary researches to lacks some properties such as Testability. In other words, due to dependence of literary researches and theories on reading, hypothesizing in literary studies is a useless and, sometimes, impossible task. Considering the implicit hypotheses instead of explicit and conventional one, maybe, we can produce a difference treatment of hypotheses for literary studies. Implicit hypotheses are not presented in the shape of a sentence, relate to step of text selecting and knot at the whole of research process.
