Education and research are fundamental pillars of educational systems, including agricultural higher education institutions. However, an inadequate balance between these components can lead to a deviation from the primary goals of these institutions. This study aimed to conduct a pathological analysis of the equilibrium between education and research in the higher education system of agriculture in Iran. “Three-pronged pathology model” was utilized, comprising components of “context” (including knowledge, moral, individual-psychological, satisfaction, and the thematic nature), “behavior” (including planning, coordination, control, and monitoring), and “structure” (including demonstrative, diversity, consequence, and political). This quantitative study is applied in purpose, non-experimental in design, retrospective in timing, survey-based in data collection, and descriptive-causal comparative in data analysis. The data collection instrument was a researcher-developed questionnaire, with face and content validity confirmed by experts. The reliability of the questionnaire was established using Cronbach's alpha for each variable (0.704 ≤ α ≤ 0.902). The statistical population comprised faculty members from agricultural departments of public universities in Iran (N=3335), with a sample of 307 selected. Results indicated a tendency among faculty members towards research activities. The greatest gap and imbalance between education and research were observed in the areas of context, followed by structure and behavior. This indicates that the existing context and structure push faculty members towards research activities for their sustainability and advancement in the agricultural higher education system. This poses a serious issue that must be addressed by policymakers and decision-makers.

In this study, the use of a mixed alumina and aluminum sulfate powder has been studied on thermal conductivity of butyl rubber filled with carbon black used as curing tire bladder composite. The aforementioned filler was added to 1.5 parts by weight in a blend of Bladder. The mixtures were prepared in the internal mixer and the curing characteristics, the mechanical and aging properties as well as the heat conductivity behavior of the composites were measured. To determine the coefficient of thermal diffusion of rubber composite, an immersion sampling method with specific dimensions in the oil bath and heat transfer computer simulation was used using a guessing and error approach. It was observed that the thermal diffusion coefficient of the above mixture rises from an average of 1×10^-7 m²/s  to an average of 1.3 ×10^-7 m²/s  without changing the mechanical and aging properties of the mixture. In the following, by choosing a simplified geometry from the tire profile in the near-tire curing conditions, and by simulating heat transfer behavior through the ABAQUS software, the effect of this increase on the thermal diffusivity coefficient was studied on the temperature variations of the inner parts of the tire. It was observed that the temperature of the different points of  tire is affected by increasing the thermal conductivity of the tire, Therefore, there is a good potential for reducing the curing time of the tire.

The following text, which has been emerged from the research on the period of power transition from Qajar to Pahlavi, unlike the approaches that are based on traditional history, according to the Foucauldian discourse analysis and the post-colonial literature, offers differentiatedscrutiny on how the first modern statehas been formed in Iran. The results show that the formation of the first modern state in Iran is the objective and strategic embodiment of the imperative modernity. Reconsidering the formation of imperative modernity, the influential discourse acts, the paper also which have formed the supporting elements of the foresaid formation were identified. Embarks upon the critical discourse analysis of the journals published in the period of power transition from Qajar to Pahlavi, including: Kaveh,Iranshahr, Name-e Farangestan, Ayandeh and Mard-e-Azad. Resulting categories of this discourse analysis include the following main concepts: "self and other image"; "Asking about collapse and underdevelopment", "adopting western civilization", "separation of religion from politics and public sphere", "elitism", "necessity of the imperative and authoritative state", and finally "nationalism". The intellectuals of the power transition period, as the reference group of the imperative modernity discourse, as well as the most influential strategic group, have played a major role in institutional and discourse formation of the first modern state in Iran. Here, wewell focus to analyze their discourse effects.

Since so many people are constantly trying to find sufficient evidence for the existence of God, but fail to attain that evidence, though they are not at fault, the issue of divine hiddenness takes form. Some contemporary philosophers have conducted investigations on this issue by various means, but the philosopher who first took steps to investigate this issue more comprehensively is the Canadian philosopher J.L. Schellenberg. In 2015, he proposed the argument for divine hiddenness in his book The Hiddenness Argument and presented it as a counterargument in favor of atheism. This argument claims that if there was a God, he should have provided sufficient evidence and reason supporting this belief at least for those in search of him, but this is not the case and thus, God does not exist. The aim of this paper, in addition to explaining Schellenberg's argument for divine hiddenness, will be to examine the view of Michael Rea, an American philosopher of religion, on this issue.

Historical textures of Iranian cities are the expression of our long-standing values and traditions, and preserving and reviving them can be a valuable cultural-social source for future generations. They represent the collective wisdom of our ancestors who have been able to bring such structures that combine science, knowledge, art and experience. Addressing this valuable heritage in fact guides us to the use of rich past experiences and can be a continuation of a culture that depends on historical continuity.
Iranian historic houses, like gems in precious historical textures, are a collection of history of life, art, beliefs, customs, and irani-islamic lifestyles, and they can in some way be considered as a museum of all cultural and social customs of old generations.
Today, with the revitalization and rehabilitation of this valuable heritage, in addition to the cultural and historical protection of these works and the promotion of these customs among citizens, economic stimulus has been created in the city, which has led to economic growth and urban development, and suitable economic groups for the promotion of urban incomes. The growth of the tourism and tourism industry, which is today considered one of the most important principles in attracting capitals. Through studying the experiences of world successful countries in this area, we can provide a conceptual model for recreating valuable historic houses and creating economic mobility.
Today, cities have begun to move towards the use of their relative advantages in the region and the world in the wake of the globalization of the economy and the competition between them in order to play a more significant role in this competitive market. Cities know that building capital infrastructure in city-capable departments can help them compete from other cities in order to make it more successful in this globalization process. Following these rivalries, urban management is undergoing major changes in its governance and management, and it seeks to promote economic activity, creativity and utilization in urban business networks through the creation of an entrepreneurial capital city.
Many entrepreneurial cities are trying to create a new development model for the city's economic growth by revitalizing and rebuilding the city's historic buildings and structures.
Throsby, the famous Australian economist, shares capital in addition to physical, human, and natural (environmental) capital: another kind of capital, cultural, which, unlike other forms of capital, in addition to cultural value, this kind of capital can also provide economic value.
The cultural capital is in fact the cultural heritage that brings with it achievements of artistic, cultural, norms and beliefs of the forerunners for the new generations, and in this study it is crystallized in the historical houses of the city, which is an embodiment of all these achievements in the old days
Between legacy works, historic houses as a real cultural heritage have a special place because these homes, while meeting the climate and climate requirements of each region, have a direct relationship with the cultural, religious and traditional originality of the people, as well as certain aesthetic principles. Hence, the necessity and importance of protecting historic homes is not overlooked.
Today, as urbanization has grown, problems have become more and more than ever. One of these problems is the exhausted urban tissue that lies in the heart of the old part of the city and is a memorial to the ancient history and culture of that city. The issue becomes even more important when buildings and historic monuments have become valuable in the context of these historic contexts, and this increases the complexity of urban officials to deal with and interfere with those historical texts. In addition to cultural, social and physical values, these buildings can economically provide potential infrastructural infrastructure for the city, including infrastructure and infrastructure.
Urban redevelopment has encountered different approaches and models throughout its time. Today, one of the transcendental approaches that has been taken into consideration in recent years and decades is the issue of development and economic growth through the de-mining industry and the attraction of tourists through investment in urban cultural infrastructure; this approach seeks to be soft And gradually, through investing in a valuable historical and
Today, because of the tensions in the world economy and the crisis in the face of those cities, they are struggling to rely on their cultural values and assets, and their restoration and reintegration, through their cultural and identity identities, and investing in them; find a new model of urban economic structure for themselves.
Culture-based regeneration as a modern regeneration approach supports creative industries and also protects the local identity and culture of the region. The purpose of this approach in recreating is to seek to find works of cultural, historical, ritual and artistic backgrounds, so that the exogenous factor of culture as a component of the coherence of these scattered spheres enters the cycle of recreation.
Developmental stimuli of recreation are working to create prosperity and economic activity in precious urban textures and lead to more dynamism and vitality of these sectors in traditional neighborhoods. How these stimuli impact their roles in urban growth and development it is an issue of this research.
One of the newest regeneration policies is the creation and revitalization of projects that act as stimulants in the historical context, leading to accelerating and facilitating the process of regeneration as well as leading it. Historically valuable houses through social partnerships and local capacity building can play a catalytic and stimulating role in the growth of the economic and physical development of texture in the neighborhood scale and sometimes in the dimensions of the city; and lead us to the most sustainable way on the path to the reproduction of historical textures.
The restoration of valuable historical monuments in the world, which is in fact the cultural heritage of that city or country, has a long history and its attention is different depending on the arts and culture of people of each land and different organizations and sectors are associated with it. These works, which reflect the history, cultural, social and artistic values of the past, have widespread social interests and require more attention from public institutions and the private sector.
Iran has been paying attention to this issue for many years and has taken positive steps to this day, but it should be taken into consideration that all methods should be tailored to their local and cultural conditions and that the use of Western methods without Localization and adaptation to Iranian values will not succeed.
The purpose of this study is to investigate the relationship between the rehabilitation of precious urban houses and economic growth and seek to answer the question whether investment in restoring these houses in Iran has a positive and significant effect on economic growth and urban development.

Medical centers consume large amounts of electricity, water, food and building materials to provide high quality care. Among the medical centers, hospitals consume more energy and water than many industries and produce more waste. Medical centers should look for programs to reduce energy consumption, reduce environmental impact, and manage waste disposal and medical waste. Green innovation makes this possible for these centers. Green Innovation is a set of changes in production products and processes aimed at managing waste, environmentally friendly productivity, reducing greenhouse gas emissions, environmentally friendly design, and reducing environmental impact.In order to create a green innovation culture in the organization, in the first step, it is necessary to identify and prioritize the barriers to innovation in order to eliminate them.In this study, by examining the research literature and consulting experts, 15 sub-obstacles were identified in the form of 4 main management barriers, green suppliers, human and financial resources for medical centers.Then, using BWM method, their livelihood and ranking were considered according to 12 experts, and the results showed that managerial barriers and especially lack of management commitment are the most important obstacles for green innovation in medical centers. Therefore, first of all, this concept and its advantages and disadvantages should be explained to the managers, and then other obstacles should be removed.

The definition and concept that every human has of the phenomena, while being specific and individual, is connected to the common spirit of the group and leaves a mark and memories of the group. Thinkers and critics of humanities have placed this common collective spirit and general thoughts in the category of implicit concepts. Implicit concepts that are the same as myths from a point of view.

This paper illustrates the application of S-transform and continuous wavelet transform (CWT) for fault location in combined overhead line and cable distribution networks. The high frequency transient signals originated by faults are analyzed using S-transform and CWT. The S-transform is found to be applicable in transient based fault location in distribution networks. This technique is an expansion of wavelet transform method and is based on a moving and scalable localizing Gaussian window. Taking into account this fact that the signal energy of faults has high amplitude around certain frequencies, the fault location can be identified considering the relationship between these frequencies and so-called path characteristic frequencies related to the fault traveling waves. The transient voltage signal energy is calculated using S-Transform and CWT. In order to demonstrate the effectiveness of the proposed method, the distribution networks with only overhead lines, as well as a combined system (consisting of the overhead lines and underground cables) have been studied. The IEEE 34-bus test distribution network is simulated in EMTP-RV software and the relevant S-transform and CWT analyses are carried out in MATLAB coding environment

In this paper, we describe our implementation of an interior point algorithm for large scale systems. First we identify system with small and medium methods convex optimization, then we use interior point method for identification. Finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and CPU time. Actually, in this paper, we are looking for a method that can identify large scale systems with low model order, error and CPU time of solution of simulation. Previous articles didn’t check the order of the computed model, and the relationship between the error and CPU time. We assume that the model of our simulation is ARMA. We are going to identify a large scale system and compute the error and CPU time and compare the relationships. Examined data in this paper is related to cutaneous potential recordings of a pregnant woman. These data are pendulous and have a large standard deviation; therefore, it can’t be fitted with ordinary curve fittings, so we use the smoothing spline for computing the order of the model. Finally, we checked the influence of the number of data on error and CPU time and order of model

Vitamins D and E are two common medicines for diabetes treatment. Among the main issues in this field is the release of insulin into the circulatory system. Increasing the stability of insulin hexamer is an evolving strategy in improving insulin secretion efficiency. Insulin protein is commonly found in three forms: monomer, dimer, and hexamer. In this study, for the first time, computational approaches were used to investigate the effect of vitamins D3 and E on the stability of insulin hexamer. The molecular docking results indicate six specific binding sites for these vitamins. These bind to the hydrophobic sites of insulin subunits due to their structural rings and hydrophobic properties. The G-mmpbsa analysis indicates the stabilizing role of both vitamins. The binding of these vitamins to the hexamer has significantly increased the binding energy between insulin subunits. Also, the number of hydrogen bonds between monomeric subunits of each insulin homodimer increased in the presence of the vitamins. It also significantly increases the number of internal hydrogen bonds of hexamer protein. Accordingly, vitamins D3 and E bind to and stabilize the insulin hexamer, resulting in a slower and more balanced insulin release as well as a longer half-life for the dimer in the bloodstream. These findings will pave the way to design a new strategy to regulate insulin release and increase its half-life in the blood for type II diabetes treatment. Besides, hexamer stabilization can be an effective treatment strategy for type I diabetes through slow release from an implanted biosensor system.

Stem cells are characterized by their capacity for self-renewal and their ability to differentiate into specific cell types under the influence of their microenvironment. It is known that matrix chemistry controls stem cell differentiation. Single cell encapsulations of the Mesenchymal stem cells into a semi-permeable microgel, allows a greater control of the stem cell fate. In this study, a chip for single-cell encapsulation was designed and fabricated using microfluidic technology. By using microfluidic chip, human bone marrow mesenchymal stem cells (hBMSCs) are encapsulated inside alginate and alginate-poly-l lysine (PLL) microgels. The results of long-term viability of MSCs inside alginate-PLL microgels, shows a significant increase compared to alginate microgels. Mesenchymal stem cell proliferation in alginate-PLL microgels also increased significantly on days 14 and 21. It seems that PLL improves cell adhesion and function by creating a positively charged matrix. Microscopic studies indicate that the morphology of the cells inside the microgels is spherical. However, the average diameter and volume of cells in microgels containing PLL are smaller than others, which indicates more proliferation and space limitation inside the microgels. Therefore, single cell alginate-PLL microgels provide a suitable substrate in clinical studies for tissue engineering, organ transplantation and cell therapy.

A buoyant under influence of sea waves and wind excitation experiences unwanted linear and rotational motions. These motions may affect proper performance of high precision equipment placed on the buoyant. Stable platform is one of the solutions employed for decreasing amplitude of the sea induced motions. Design of an optimal fuzzy controller for a tripod stable platform installed on the deck of a medium boat is considered in this paper. For this purpose, a fuzzy controller is proposed for the stable platform control. Furthermore, a 3D virtual model of the boat and the stable platform is developed and the fuzzy controller is applied to the virtual prototype using the co-simulation technique of MATLAB and ADAMS software. The fuzzy controller is then optimized using the genetic algorithm (GA). Moreover, a linear quadratic regulator (LQR) is designed for the stable platform control. The controllers are then applied to the virtual prototype and their performance in the presence of sea wave excitations is examined. Simulation results reveal that the tripod stable platform controlled with the optimal fuzzy controller can reduce pitch and roll motions up to 90 percent and reduce heave motion up to 55 percent.

Sheet metal components frequently are used in industry. There are several methods to produce them. Progressive die one of the most widely applied devices to sheet metal components manufacturing. The progressive dies reduce the time and cost of producing complex sheet metal components. However, the design and manufacture of these dies are difficult. CAD/CAM systems have been proved to be very useful tools for this task. In this paper, two the important stages of die design process, Nesting and Piloting system are studied. By using fuzzy set theory and three fuzzy rules: scrap percentage, type of pilots, distance between pilots, the optimum state of nesting and piloting is determined. These rules are applied according to expert comments and industrial observations. According to our investigation, piloting accuracy impresses the final nesting design, thus a new fuzzy rule based on distance between pilots is proposed in this paper. The presented method is based on algebra algorithm that it determines suitable and exact place of semi-direct and indirect pilots and decrease calculation time. Three components taken from industry and previous papers are used to show the capability of the proposed method.

Control of seismic shake table in order to track the predefined earthquake profile is a key concern in design of seismic shake tables. This paper proposes a vision-based real time displacement measurement system using image processing techniques to control a laboratory-scale seismic shake table. The shake table is controlled via a fuzzy-supervisory controller, an inner PID loop and a Fuzzy outer one, whose feedback is provided by the vision-based measurement system. To minimize tracking errors, the fuzzy controller uses displacement and acceleration responses as its feedbacks. For this purpose, a camera and an image processing application are utilized to measure the motions directly in real time. Results are sent to a host PC through a network as the controller feedback. Proposed system performance is compared with an alternative system which utilizes a linear encoder as displacement sensor and controller feedback. Test results prove effectiveness of the proposed fuzzy system in cutting back the tracking errors. In addition, the vision-based system uses a very low cost camera to measure the displacement directly. It has appropriate accuracy, works in real time, and doesn't need any contact with the table, comparing to the encoder version.

Milling is one of the most important operational stages in processing the minerals. Lifters are usually used with mill liners to extend their life and to enhance the grinding and crushing efficiency. Lifters worn and consequently their dimensions change during the course of operation. These changes in dimensions have a significant influence on the overall economic performance of the mills. Therefore, it is useful to know the relationship between the mill operation and the lifter profile, and the influence of lifter wear on the change in lifter profile. The wear is influenced by a range of parameters such as: media charge level, slurry filling, slurry concentration, and mill speed. In this work, the influences of these operating parameters were investigated using a pilot mill (1000 * 500 mm). To this end, a Copper ore was used to prepare slurry at 40%, 50%, 60%, 70%, and 100% solids concentration by mass. The tests covered a range of slurry filling (U) from 0.5 to 3 with solid charge between 15% and 35% of mill volume and 3 different speeds 65%, 75% and 85% of critical speed. It is found that the mill charge and the mill speed significantly affect the wear rate. For wet condition, increase in the slurry concentration and slurry filling leads to a remarkable decrease in the amount of the wear. By increase in the feed filling (in dry condition) the wear increases too. Wear rate in wet conditions is 2-4 times of dry condition.

A novel approach is presented for the reconfiguration of satellite constellations based on Lambert’s theorem. The reconfiguration problem, in this article, is considered with the constraint of overall fuel cost minimization. Hence, orbital maneuvers required for the operation of reconfiguration is designed in such a way that, transferring the satellites to the desired configuration of constellation will be possible at minimal cost. Also, the introduced method of orbital transfer for implementing the reconfiguration phase of satellite constellation has no limitation on the shape and orientation of initial and target orbits such as: co-planarity, coaxiality, circularity and/or the existence of a common point. Moreover, a method is offered for modeling the cost function of reconfiguration problem in which the two important tasks of optimal orbital transfer of satellites to the target configuration of constellation and optimal assignment of each satellite to a specific terminal position or final orbit will be done in one single step. For this purpose and in order to achieving the globally optimal solution of the reconfiguration problem of constellation the hybrid PSO/GA is used. Finally, two different scenarios of reconfiguration of satellite constellation will be modeled once by the presented approach and once by considering determined positions of flight and deployment for the satellites. The obtained results indicate the superiority of the idea presented in this article.

 In thisresearch, for the first time, the replacement of valerian extract with chemical preservatives in orange
juice has been investigated. Whey Permeate Powder is also used as a source of minerals and vitamins in orange
juice. In this experimental study, an antioxidant effect of valerian extract was determined and its
compounds were determined. Then, the effect of juice extract on three levels of 1.25, 0.63 and 0.13 ml
and 1.5, 1 and 0.5 percent of whey permeate powder on the chemical properties of orange juice during the
storage period in three intervals. The period of 1, 14 and 30 days was studied. The tests performed on
prepared samples including: formalin index, acidity, vitamin C, pH and antioxidant properties, and the
results obtained by Expert design-7 software are analyzed and shown in the diagram. The results indicated that the pH increased at high levels of whey permeate powder and extract during the period of 1, 14 and 30 days. Also, the decreasing in acidity with increasing whey permeate powder percent is probably due to the low acidity of whey permeate powder to the extract and the sample of orange juice's control (is a witness). By adding single levels of whey permeate powder and extract, the vitamin C increased and then decreased with increase of during maintenance. Also, the effect of valerian extract was greater than whey permeate powder in vitamin reduction over a period of time.

High temperature creep in nickel-based superalloys is investigated by discrete dislocation plasticity (DDP). A two-dimensional unite cell model representing micro-structure of superalloy and comprising γ^' particles in γ matrix phase is considered under uniaxial constant stress loading. While plastic deformation of γ phase occurs by a combination of dislocation glide and dislocation climb coupled to the diffusion of vacancies, elastic γ^' particles undergo deformation due to the stress-driven interfacial diffusion at the γ/γ^' interfaces in addition to bulk elastic deformation. It is noted that diffusion of vacancies is explicitly considered where local concentration of vacancies determines climb of dislocations. This model predicts the onset of tertiary creep in superalloys as extensively observed in experiments for commercially important nickel-based superalloys at moderate stress and temperature levels. Possible associated mechanisms are accordingly discussed. Moreover, effects of parameters such as volume fraction of γ^' particles are studied and discussed. Superalloys with three values for volume fraction of γ^' particles are investigated and obtained results indicate that the volume fraction of γ^' particles plays an important role in the creep behaviour of superalloys. Results of this study can be used in a continuum constitutive rule to investigate structural components under operational conditions.

The purpose of this paper is to design a control systwm with a pre-designed algorithm in order to reach a compromise between satellite attitude and thermal control systems. In addition to the indispensable attitude control system, a thermal control system (TCS) is regarded as a substantial subsystem in any given satellite. The latter is commonly used to effectively reduce the internal heat and/or the thermal tensions caused by solar radiations. In this paper, a novel actuators known as fluid momentum controllers (FMCs) have been utilized to simultaneously produce control torques and develop a cooling mechanism by circulating liquid through a ring. In this research, it has been assumed that the satellite’s internal temperature has reached a critical level to the extent that the FMCs are not able to reduce this temperature sufficiently. In such a case, it is possible to mitigate this problem using a combination of both attitude and thermal control subsystems (CATCS). To accomplish this, a thermal model has been employed to yield the temperature of all six sides of the satellite at each time step and a switching algorithm to design an integrated system. This algorithm uses a particular decision making logic to realize the reconciliation of the two subsystems. Also, a sliding mode controller has been used for the three axis stabilization of the satellite. Simulation results of the integrated attitude and thermal control system indicate that it is possible to conduct an appropriate temperature control while saving power and integrating the two subsystems.
