The present study was conducted with the aim of critically analyzing and comparing the views of Paynar and Eisner in the field of curriculum. To achieve this goal, comparative research method has been used. The field of research included all the sources, including the books of these scientists, articles, studies and research related to the subject. The research sample was selected purposefully so that sources with relevant and first-hand materials are selected. The desired data was collected through a note-taking list and the information was analyzed verbally, graphically and logically. Based on the findings of the research, Paynar considers the curriculum as a cultural and political structure and has paid attention to concepts such as phenomenology, neo-conceptualism and internationalization of curricula, and Eisner has paid attention to aesthetics, artistic education and the view of plurality and to the orientation in the development of curricula, with a critical and comparative look at the macro views of these two scientists in the field of curriculum. It can be concluded that the common point of view of these two scientists is to pay attention to the real world in designing curricula, but their distinction is Paynar's attention to theorizing in the field of curriculum with respect to the real world, and Eisner pays attention to the artistic and aesthetic point of view in curriculum design.

According to Moradi et al.'s article (1401), the auditing paradigm model of the supreme audit court in the process of granting facilities to knowledge-based companies was extracted by the qualitative method and applying the grounded theory research method. The purpose of this study is to measure and prioritize the dimensions and components of the above model by means of a questionnaire extracted from the findings of Moradi et al.'s article (1401).This research has been done using a quantitative descriptive survey method and using the structural equation model as well as Friedman's test. The statistical population of the research included all the employees of the supreme audit court, based on Cochran's formula, 342 people were selected as the sample size and it was done by simple random sampling. For data analysis, the structural equation model was used under smartpls3.3 software. The results of the findings indicated the fit of the initial model, so that the causal conditions (human resources and organization of the supreme audit court, personal and professional characteristics of the auditor), contextual factors (the position of the supreme audit court and society's demands from it, legislation and enforcement and monitoring institutions) and Intervention conditions (international conventions and standards, information technology, limits of disclosure and politicization, culture and values of society) is effective on the central phenomenon (auditing of the supreme audit court in knowledge-based companies) and the central phenomenon is on strategies (the auditing of the supreme audit court, the supporting organization of the knowledge company, examination of knowledge-based companies, internal control of the supporting organization) are effective and finally the strategies are effective on the consequences (results for the beneficiaries).

In this study, silver nanoparticles (Ag-NPs) as catalysts in the photocatalytic degradation reaction of Sunset Yellow FCF (SYF) azo dye in aqueous solution were investigated. Ag-NPs were prepared by using walnut (Juglans regia L.) leaf extract. The synthesis of Ag-NPs has been done using green chemistry, which is an environmentally friendly, low-cost, fast, and safe method. Extraction was done with a facile method, as well as the synthesis of Ag-NPs in a short period and with high efficiency. The Ag-NPs were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDS), X-Ray Diffraction (XRD), and Fourier Transform InfraRed (FT-IR) spectroscopy. Optimum conditions for dye degradation were determined using Taguchi experimental design method with (L9(34)) orthogonal array. Analysis of the response of each experiment was based Signal to Noise (S/NL) ratio calculated. The effects of operational parameters such as catalyst amount, pH, irradiation time, and temperature in three levels for each factor were studied. The Taguchi results showed that catalyst amount= 20 mg/l (level 2), pH= 4 (level 1), irradiation time = 45 min. (level 3) and temperature= 30 °C (level 3) was the optimum conditions for this process. The most influence of each factor on the process was determined using the Analysis of Variance (ANOVA) method. The most significant factor in this process was pH. The interaction between pH×catalyst amount was the most influencing interaction. The analysis of primary ANOVA showed that percent (p(%)) parameters were: catalyst amount (12.002%), pH (46.298%), irradiation time (35.311%), and temperature (6.383%). The contribution of factors in this process was found to be in the following order: catalyst amount (0.142), pH (0.431), irradiation time (0.397), and temperature (0.18). A pseudo-first-order kinetic reaction with rate constant k=0.0721 min−1 was observed for dye photocatalytic degradation.

In this research, we investigate the effect of carbon nanotubes (CNTs) as a substrate on the morphology, size, magnetic behavior, and band gap energy (Eg) of nickel ferrite nanoparticles. Synthesis of NiFe2O4 nanoparticles carried out using a direct co-precipitation method in aqueous solution containing carbon nanotubes. The samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-visible Spectrophotometer, and vibrating sample magnetometer (VSM). The results showed that using the CNT as a supporter reduced the size and band gap energy of NiFe2O4 nanoparticles, changed the morphology of the powder from an aggregate state to a filament state and it increased the magnetic saturation properties of nanoparticles.

In this research, the thermal-hydraulic behaviour of fluid in the shell and tube heat exchanger with new segmental perforated baffles and hollow spiral baffles with basic structures (simple segmental and simple helical) were investigated. By using evaluation parameters such as heat transfer, pressure drop, ratio of heat transfer to pressure drop, and efficiency evaluation coefficient (EEC), the effect of the proposed baffles was compared with the basic structure (segmental baffle, single pass helical baffle). Based on the obtained results, the perforated continuous helical baffle reduced the pressure drop by 22.46% compared to the simple helical baffle and the perforated segmental baffle reduced the pressure drop by 19.76% compared to the simple segmental baffle. In a more comprehensive evaluation, the efficiency evaluation coefficient of pore helical and segmental baffle structures showed an increase of 18.3 and 11.17 per cent, respectively compared to the basic configuration. The concept of changing the flow pattern from helix to helix-longitudinal and from zigzag to zigzag-longitudinal made the flow distribution on the shell side more uniform. These conditions reduced areas prone to sedimentation (dead areas) and maintenance costs, and improved system performance. In addition, this new structure can replace conventional segmental baffles to save energy in the long term.

Brassicaceae is a medium-sized family of flowering plants. The family contains more than 327 genera. Cardamine uliginosa is a type of plant of this species. Chemical and biochemical findings of this genus are very limited. This study aimed to investigate the chemical compounds and antioxidant and antibacterial properties of C. uliginosa.

Essential oil was prepared by hydrodistillation method and microwave assisted hydrodistillation (MAHD). The chemical composition of essential oil was evaluated by GC and GC-MS methods. The antioxidant property of the hydroalcoholic extract was investigated by 2, 2-dipheny1-1-picrylhydrazyl (DPPH) solution. Finally, the antibacterial activity of C. uliginosa was investigated using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) methods.

Phetalic acid, Phenil, Caryophyllene, Eicosane, and other chemical compounds were found in the essential oil of C. uliginosa. The half maximum inhibitory concentration (IC50) of hydroalcoholic extract was 0.42 μg/mL. The MIC and the MBC against both Escherichia coli and Staphylococcus aureus were 15.62 and 31.25 respectively. The major compounds in the essential oils were 3-methyl-4-isopropylphenol (15.20%) and 1, 2-benzenedicarboxylic acid (16.75%).

Considering the chemical compounds of C. uliginosa and the finding of the antibacterial and antioxidant activity of C. uliginosa in vitro, capability of this plant needs to be further investigated for use in health and medical industries.

Successful artificial insemination requires successful collection,sperm evaluation and the addition of preservatives to sperm shelf life.Despite many efforts and addition of protective and antioxidant substances ,the quality of frozen-thawed sperm is low and the resulting fertility is not acceptable.For this reason,in this research,the cooling method has been used insted of freezing.The aim of this investigation was to assess the effect of apricot gum adding to tris-base diluents on liquid ram semen storage and ewe pregnancy rate.

This study was conducted in the khalatposhan research station of Tabriz University,EastAzarbyjanProvince,Iran.semen was collected by artificial vagina twice a week during the breeding season. A total of 25 ejaculates were collected from 5 Ghezel rams. Average age of rams was 3 years.Immediately after collection,each ejaculate was immersed into a water bath maintained at 37 ℃ prior to evaluation.The semen samples were evaluated for volume,wavemotion,spermconcentration,membraneintegrity,Ph,totalmotility,progressive motility and viability by routine examinations. The volume of ejaculate by graduated tube (shamsuddin,2000). To evaluate the wave motion,a drop of undiluted semen was placed on a pre-warmed slide 37℃ without a corerslip and examined underphase contrast microscope(100×)(Nikon,Eelpse,E200,Japan). Fresh semens have been studied in terms of volume,concentration,total motility,viability and morphology and only samples with over 2.5 billion sperm and a progressive motility of over 70% were used for dilution.Semen samples was diluted with tris(2.71g),citric acid(1g),fructose(1.4g),penicillin(100,000IU) and streptomycin(100mg) in 100 ml distilled water.Then 73 ml of this solution was mixed egg yolk(20ml). One gram of solid apricot gum was dissolved in 10ml sterile distilled water to prepare the liquid apricot tree gum. After diluting the semen samples, it was divided into four equal parts and three parts were added to 100,150 and 200 µl/ml of apricot tree gum diluting liquid,respectively,and one item(control group) no material was added.Diluted semen samples were poured into 2ml microtubes and placed in a container containing 37Ċ water in the refrigerator for 90 min to slowly reach 5Ċ.Semen samples were evaluated every three days for 36 days. In this study,12 ewes were artificial inseminated by cervical insemination and all three ewes were ineminated with one treatment.Sperm used for artificial insemination were stored for 24 hours.The artificial inseminated ewes in this experiment,were 4 years old.Data were analysed using the Glm and mixed procedures of SAS 9.2 software.

In this investigation, it was observed that adding apricot gum at all levels of 100,150 and 200µl did not have a significant effect on sperm quality until the third day after cooling to tris-base diluents in all three concentrations of 100,150 and 200µl after the third day after cooling(P>0/05).but after the third day of cooling significantly improved sperm quality parameters such as viability,total motility,progressive motility,morphology and membrane health(P<0/05).but between there was not any significant difference between treatments with apricot gum(P>0/05).In this study,12 ewes were artificial inseminated by cervical insemination and all three ewes were ineminated with one treatment.Sheep inoculated with control treatment had 33.33% fertility,100 and150µl apricot gum treatment had 66.67% fertility and 200µl apricot gum treatment had 100% fertilityMammalian sperm cells present highly specific lipidiccomposition,high content of polyunsaturated fatyacids,plasmalogenes and sphingomyelines.This unusual structure of sperm membrane is responsible for its flexibility and the functional ability of sperm cells (Sanocka and Kurpisz,2004).However,spermatozoa,s lipids are the main substrates for peroxidation ,what may provoke server functional disorder of sperm (Aitken,1989).A reason for higher,pathological lipid peroxidation of sperm membranes can be un balanced oxidative stress (Sanocka and Kurpisz,2004).The spermatozoon like all cells living under aerobic conditions,constantlv faces the oxygen paradox;oxygen is required for life,but oxidative metabolism of biological molecules can be potentially toxic because of the formation of highly reactive oxygen species(ROS)that can modify cell functions or viability (Aitken and Clarkson,1987).Reactive oxygen species leak from mitochondria in to the cytoplasm were they cause cellular damage by oxidizing a variety of biologically important molecules including DNA,proteins,lipids and carbohydrates (Przekwas,2003).Also oxidative stress by an imbalance of oxidants and antioxidants in favour of the former and is capable of inflicting injury on membrane lipids,proteins and nucleic acid (Toyokuni,1999). Endegenous antioxidant are sufficient to prevent free radicals that are produced in the normal state in the cells but an increase in free radical production leads to oxidative damage (Bunker,1992).Natural polysaccharides and their conjugates have been widely used in food and medicine fore long time.Numerous biological and pharmalogical favourable effects of natural polysaccharides have been extensively studies in a vitro and in animal models in vivo and more kinds of natural polysaccharides have been tested and even applied in therapies (Wang and Fong,2004;Liu,2016).It was demonstrated that some natural polysaccharides were effective at preventing oxidative damage in living organism this could be a potential resource of novel antioxidants (Tsiapali,2001).It is well described that the reducing capacities of polysaccharides is related to their sulfation rate molecular weight,glycosidiclinkages,hydroxyl groups but also carboxylic groups of uronic acids (Hentati,2018).It was previously reported that adirect correlation between the antioxidant activity and the reducing power of polysaccharides (El-shaurbagy GA,2014).Indeed,this antioxidant activity is explained by the presence of many free hydroxyl groups in the structureChemical analysis of apricot gum was performed in (2012) by the LIuveras-Tenoria.They found total sugars(60%),galactose(43%),mannose(4%),arabinose(44%),xylose(7%) and ramnose(1%) in apricot gum (LIuveras,2012). of polysaccharides. In addition, some papers reported that the presence of arabinos in the structure of polysaccharides could reduce the production of hydroxyl radicals by chelation of pro-oxidant ions(Lefish,2018).In a study conducted to investigate the effect of adding xanthan gum to horse sperm diluents,the researchers reported that adding xanthan gum to the diluents reduces sperm motility compared to the control group,but in other sperm quality parameters,they did not see a significant difference with the control group,which is inconsistent with the findings of our research(Gheller,2019).In another experiment to investigate the effect of substituting Gum diluents on teacling increased the storage time of semen better than the control grup and in Arabic for egg yolk in ram sperm diluents,researchers reported that substituting Gum Arabic for egg yolk increased the belief of artificial inseminated ewes which is consistent with the results of artificial insemination of sheep in our study(Zeitoun,2017). The study found that adding apricot tree gum to the tris-base treatments with apricot tree gum sperm quality is was better than in the control grup.So far,no research has been conducted to investigate the effect of adding apricot tree gum to semen diluents and this study was conducted for the first time.

In general,the results of this study showed that the addition of Apricot Gum to tris-base diluents due to regenerative reviews increases the quality and longevity of ram liquid semen and increases its fertility.

Equitable distribution of health care sector resources is one of the most important goals of health systems in all countries. The purpose of this study is to measure equity of geographical distribution of active specialist physicians in Iran’s health system.

The present study was a descriptive‑cross‑sectional. The statistical population included: all active specialist physicians working in the public, private, social insurance organization, military, charity, and the other health service providers in Iran in 2019. Studied demographic data were collected from Iran’s national statistic center. Also, information of specialist physicians was obtained from several databases. Finally, duplicated records were removed, and the number of specialist physicians extracted. Data analysis was performed using Stata V.16 and ArcGIS 10.4 software.

The results showed that the number of specialist physicians per 100,000 population who worked in Iran’s health system was 46.81. The provinces of Tehran had the highest and Sistan and Baluchestan had the lowest number of specialist physicians. Also, 52.63% of active specialist physicians provide health services in four provinces, whereas these provinces are 37.13% of the country’s population. Total Gini coefficient of the distribution of active physicians in Iran in 2019 was 0.23.

Distribution of specialist physician was different but somewhat equitable in the provinces. However, in some provinces, the ratio of specialist physicians to the population was still low. Therefore, when the number of specialist physicians increased, their distribution should be considered concurrently.

The purpose of this study is to present the audit model for the supreme Audit Court in the process of granting facilities to knowledge-based companies.

These dimensions include the individual dimension (including axes; personality, perceptual skills, and appearance), Organizational dimension (including factors; commitment, professional development, organizational participation, professional motivation, communication and satisfaction), It is the social dimension (including factors; social values and social relations) and the dimension of the teaching and learning process (including factors; observance of educational rules, teaching, Evaluation and research and writing).

Caryophyllaceae is a large family of about 2200 herbaceous or subshrub species. Vaccaria oxyodontha Boiss is of the family Caryophyllaceae. This plant grows as a weed in agricultural land of sugarcane, wheat, barley, forage, and summer crops such as sugar beet, potato, cotton, and onion. All parts of the V. oxyodontha Boiss plant, especially its root, contain a type of saponin, which shows its medicinal value. According to traditional Iranian medicine, this plant is a blood purifier and has anti-infective, utilized for cough, anti-rheumatism, and anti-inflammatory properties. This study first aimed to investigate the chemical composition of V. oxyodontha Boiss essential oil (EO) and the antioxidant and antibacterial properties of the hydroalcoholic extract of this plant on gram-positive and gram-negative bacteria.

In this study, EOs were extracted from the aerial parts of V. oxyodontha Boiss using the combination of hydrodistillation and microwave-assisted hydrodistillation methods. Then, the antioxidant properties and antibacterial activity of the extract were evaluated, and the chemical compositions of the EOs of V. oxyodontha Boiss were determined using gas chromatography-mass spectroscopy (GC-MS). The extract’s antioxidant activity was studied by the 2,2-diphenyl-1-picrylhydrazyl-hydrate (DPPH) method. In addition, the plant antimicrobial effects were investigated by the agar disk diffusion method, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined as well. Finally, the antibacterial activity of the mentioned plant was compared with the antibiotic discs of gentamicin (10 mg) and vancomycin (30 mg).

The major compounds in the EOs were 2-Pentadecanone,6,10,14-trimethyl (10.52%) and 1,2-Benzenedicarboxylic acid (19.27%). Half maximal inhibitory concentration (IC50) of V. oxyodontha Boiss was 0.49 μg/mL, which was higher than that of vitamin C (IC50 value of 0.56 μg/mL). Further, MIC and MBC for the V. oxyodontha Boiss extract against Staphylococcus aureus and Escherichia coli were 62.5 and 125 mg/mL, as well as 31.25 and 62.5 mg/mL, respectively.

The results of GC-MS demonstrated that the EO of the V. oxyodontha Boiss plant contains antioxidant and antibacterial compounds. Its antioxidant properties are higher than vitamin C. The highest diameter of the inhibition zone caused by the methanol extract of the V. oxyodontha Boiss plant was against S. aureus and E. coli (23.7 ± 0.29 mm and 15.65 ± 0.33 mm, respectively). Compared with the antibiotics vancomycin, the Vaccaria oxyodontha Boiss represented a stronger inhibitory effect in the inhibition of S. aureus (P < 0.05).

This study experimentally examines types of rotational-friction dampers with two slip load and numerically analyze the behavior of a reinforced concrete frame with these dampers under cyclic loading. To this goal, the study will explain the mechanism of proposed damper’s action after the introduction. In the next step, two specimens of rotational-friction dampers with two different slip load are investigated in the laboratory. Using OpenSees software, the proposed behavioral model is validated by experimental results. In the final step, a frame of one-story reinforced concrete that had one bay was analyzed under cyclic loading in four states including (1) without damper, (2) with a rotational-friction damper that had one slip load (RFD), (3) with a rotational-friction damper that had two slip load type S01, and (4) with a rotational-friction damper that had two slip load type S02. The obtained results were discussed and examined after these analyses. The results of the numerical analysis also show that the concrete frame with S01 damper has better seismic performance. This is because its ultimate strength and dissipated energy are respectively 15% and 164% more than the ultimate strength and dissipated energy of the frame without damper, at the last cycle.

In this paper, cobalt ferrite (CoFe2O4) nanoparticles were synthesized using the precipitation method. CoFe2O4 nanoparticles were used as a catalyst for photocatalytic degradation of azo dye in an aqueous solution. Acid Yellow 23 (AY23) was used as a model dye. The CoFe2O4 catalyst was characterized by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). A batch photoreactor with a capacity of 1L, equipped with a lamp UV-C (15 W) was used. A statistical experimental design based on Yates’ Algorithm was exerted to measure the effect of these four factors such as pH, catalyst amount, H2O2 concentration, and temperature at two levels. The (24 ) full factorial experimental design was utilized in this process. The significant effects of each factor and interaction on the process were determined using the Analysis of Variance (ANOVA) method. A pseudo-first-order reaction with a constant rate (k= 0.048 min−1 ) was obtained for the photocatalytic degradation reaction.

In this paper, the precipitation method has been used to stabilize Fe2O3 particleson Bentonite zeolite (BEN). Fe2O3/BEN catalysts have been characterized byscanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) surface area analysis. Artificial neural network (ANN)was used for modeling the photocatalytic degradation of Sunset Yellow FCF(SYF) azo dye in aqueous solution under irradiation in the batch photoreactor.The parameters including pH, catalyst amount, dye concentration and H2O2concentration was applied as input; the output of the network was degradationpercentage. Modeling the results of the photocatalytic degradation of dye using afeed-forward, backpropagation three-layer network, topology (4:7:1) with fourneurons in the input layer, seven neurons in the hidden layer, and one neuron inthe output layer was used. Comparison between data obtained from ANN andexperimental data indicated that the proposed ANN model provides reasonablepredictive performance. The optimum conditions were as follows: pH= 4, catalystamount=60 mg/L, dye concentration =50 ppm and H2O2 concentration =32ppm. The chemical oxygen demand (COD) analysis of the dye under optimumconditions showed a 91% reduction in 80 min period.

Alpha-lipoic acid (ALA) as a strong antioxidant has a protective effect. This study was designed to assess whether supplementation of maturation medium with ALA during in vitro maturation (IVM) can attenuate the toxic effect of ethanol.

In this experimental study, to assess the antioxidant capacity of ALA challenged by 1% ethanol during in vitro maturation, immature ovine oocytes were exposed to 1% alcohol in the presence or absence of 25 µM ALA during oocyte maturation. The cumulus expansion index, intracellular reactive oxygen species (ROS), and thiol content levels were assessed in matured oocytes of various treatment groups. Consequently, the blastocyst formation rate of matured oocytes in various treatment groups were assessed. In addition, total cell number (TCN), cell allocation, DNA fragmentation, and relative gene expression of interested genes were assessed in resultant blastocysts.

The results revealed that alcohol significantly reduced cumulus cells (CCs) expansion index and blastocyst yield and rate of apoptosis in resultant embryos. Addition of 25 µM ALA to 1% ethanol during oocyte maturation decreased ROS level and elevated Thiolcontent. Furthermore, supplementation of maturation medium with ALA attenuated the effect of 1% ethanol and significantly increased the blastocyst formation and hatching rate as compared to control and ethanol groups. In addition, the quality of blastocysts produced in ALA+ethanol was improved based on the low number of TUNEL positive cells, the increased expression level of mRNA for pluripotency, and anti-oxidant markers, and decreased expression of apoptotic genes.

The current findings demonstrate that ALA can diminish the effect of ethanol, possibly by decreasing the ROS level and increasing Thiolcontent during oocyte maturation. Using the ALA supplement may have implications in protecting oocytes from alcohol toxicity in affected patients.

Nowadays one of the challenges that engineers and structural designers encounter is reduced vibrations of structures due to lateral forces such as earthquakes and winds. Taking into consideration that the design and construction of tall buildings is one of the most common methods of land-use in highly populated urban areas, the necessity and importance of identifying methods of controlling structural vibrations is felt more keenly than before. One of the methods of structural motion control is passive structural motion control with friction dampers. In this study, the main focus on the application and performance of friction dampers is new ideas for using the friction phenomenon to control structural vibrations and the design challenges of structures with friction dampers. For this purpose, first, we try to point out the important concepts in vibration control. Then, the goals, methods and results of various existing researches are examined to provide a clear view of friction dampers for structural engineers and as a start for future research to develop and improve the performance of friction dampers.

Coronary Artery Disease is one of the leading causes of death in the world. CAD usually progresses slowly during time and patients with normal or near-normal coronary arteries are also at risk of developing CAD. It is now believed that even mild atherosclerosis can increase the rate of CAD.

This is a retrospective, descriptive and analytic study. We selected patients who had undergone at least two diagnostic coronary angiographies at Tehran Heart Center and had normal coronary structure or mild CAD in initial angiography. The data was obtained from the Tehran Heart Center Angiography Databank. Predicting factors in the development of CAD were determined.

Data on 556 patients were reviewed. The median interval between the initial and final coronary catheterization was 37.6 months. On the final evaluation, 216 patients (38.8%) found to have developed some degrees of coronary artery disease. Based on the multivariate analysis, age, hematocrit, cigarette smoking, hypertension, and initial presentation with stable and unstable angina were found to be independent predictors of progression to CAD in patients.

In the end, 40% of patients who had normal coronary arteries or minimal CAD in the initial angiography report, developed some degrees of CAD and some clinical indices can predict the risk of CAD.

Loyalty to the destination is one of the most important issues in tourism research. Tourism loyalty analysis is an important issue in tourism management.  The main purpose of this study is to investigate and analyze the loyalty of tourists in Shiraz.

The statistical population of the study is tourists visiting Shiraz in 1398. The Cochran's formula was used to calculate the sample size, according to which the sample size was estimated to be 384 people, and a simple random method was used to distribute the questionnaire. The data are collected in a methodical and informative manner. The results showed that the level of loyalty of tourists in Shiraz, including combined loyalty with 19.10, behavioral loyalty with 6.70 and attitude loyalty with 12.40 is higher than average.

Emphasis on reading comprehension skill of foreign language learners is one of the most significant methodological topics in language learning and teaching. Moreover, individual differencesof learners such as emotional intelligence (EI), autonomy, self-regulation (S-R), and willingness to communicate (WTC) have been recognized as very influential variables in the process of language learning. Therefore, exploring the effects of these variables can be very helpful in the process of foreign language learning, including reading comprehension. Until now, in the literature of teaching and learning Persian as a foreign language, no study has been conducted on the possible relationships or effects of emotional intelligence, autonomy, self-regulation, and willingness to communicate on reading comprehension of Persian foreign language (PFL) learners. The present study attempts to fill this gap. Consequently, the purpose of this nationwide study was to explore the relationships between emotional intelligence, autonomy, self-regulation, willingness to communicate and reading comprehension ability of Persian Foreign Language learners in Iran. For this end, 141 non-Persian students, from 28 different countries in the world, majoring in various fields at 12 universities across Iran, participated in this study. The selected universities were located in the north, south, east, west, center, and other parts of Iran. The universities were: University of Isfahan, Imam Khomeini International University, Bu-Ali Sina University, Shahid Beheshti University, University of Tehran, Shiraz University, Allameh Tabataba'i University, Ferdowsi University of Mashhad, University of Mazandaran, Malayer University, Yazd University, and Yasouj University. The diversity of Persian foreign language learners shows the increasing significance of this language worldwide. The participants were asked to answer a reading comprehension test and the translated Persian versions of emotional intelligence, autonomy, self-regulation and willingness to communicate scales. The results of Pearson Correlation Coefficient indicated that there were positive significant relationships between the four variables; i.e. emotional intelligence, autonomy, self-regulation, willingness to communicate and reading comprehension. The results also revealed positive significant relationships between all sub-components of emotional intelligence (self-emotion appraisal, others' emotion appraisal, use of emotion, and regulation of emotion), autonomy (self-management, willingness to learn, and self-control), and self-regulation (planning, self-checking, effort, and self-efficacy) and reading comprehension. Moreover, in order to assess the strengths of predicting the four independent variables and their sub-components of reading comprehension, multiple and standardized regressions were run. The obtained results showed that the four independent variables and most sub-components were strong predictors of reading comprehension. Also, for providing more insights about the variables and estimating the strengths of the causal relationships among them, Structural Equation Modeling (SEM) was utilized by AMOS 24. The four independent variables were strong predictors of reading comprehension (emotional intelligence: 0.29; autonomy: 0.18; self-regulation: 0.16; and willingness to communicate: 0.43), with WTC being the strongest predictor. Foreign language learners, especially Persian foreign language learners, foreign language teachers, and all individuals involved in foreign language teaching and learning can benefit from the results of the current study. Learners must be aware of their own individual differences and their important effects in their reading comprehension ability and ultimately in the process of foreign / second language learning. They must know that by being able to use their emotions, willingness to communicate, taking responsibility of their actions, and also being actively involved, they are deemed to succeed in their endeavor of learning a foreign language. Teachers, too, can provide great help by becoming aware of the role of learners' individual differences. They can emphasize tasks that utilizes learners' emotional intelligence, autonomy, self-regulation, and willingness to communicate. Curriculum developers, syllabus designers, and materials producers must also pay special attention to these variables. In general, individual differences are very vital in the process of foreign / second language learning and many researchers in Iran and across the world have underlined their role in language learning, and specifically in reading comprehension ability. However, the significance of this study is on the grounds that no study had been conducted to investigate the effects and relations of these variables on reading comprehension for Persian as a foreign language. At the end, we should emphasize that this study did not consider age and gender of the participants. We suggest future researchers explore the effects of these variables. Also, interested researchers can explore the effects of these variables on other language skills; that is, listening, speaking, and writing. There are also other uninvestigated individual differences, such as self-efficacy, creativity, critical thinking, self-esteem, etc. that researchers can study. We hope that the current study and future studies shed light on the role of individual differences on learning Persian as a foreign language.

Abstract   Background and Objectives International forces and public pressure to prevent environmental pollution have changed burnt sugarcane harvesting to green sugarcane harvesting in most important sugarcane-producing regions of the world. In the major countries that produce sugarcane, sufficient research has been done on green sugarcane harvesting. Due to climate difference between Iran and other countries, it is essential to investigate all the aspects of green cane harvesting such as the quality indices of extracts in Khuzestan, Iran.   Materials and Methods To compare extract quality in burnt and green sugarcane harvesting, a test was performed in 2015-2016 at Emam Khomeini Agro industry company (latitude 31,44o N, longitude 48,44o E and 24 m asl). A spilet plot design was used. Three sugarcane varieties with different ripeness durations were considered as the main plot and five harvesting methods and ratooning including burnt harvesting, green cane harvesting without rationing, green cane harvesting with rationing, green cane harvesting with one reshape replication and green cane harvesting with two reshape replications with four replications were considered as the sub plot. Trash percent, extraction percent (Ex), total solid material solute in extract (Brix), sugar percent in extract (Pol), extract purity degree (Pty), recovery sugar percent in factory (R.S) and the yield were studied.   Results Results showed the varieties had a significant difference regarding all the parameters except Ex. Maximum Ex (%41.863), and the yield (93 t/ha) belonging to Cp69-1062 varieties. Cp73-21 had the maximum Brix (%20.35) and Pol (%18.16). Methods of harvesting and ratooning caused a significant difference as to the trash percent, R.S, the yield and Brix. The mean of trash in green harvesting was 7 %but it was 4% in burnt harvesting. Maximum Brix belonged to the burnt but had no significant difference with that of the green harvesting. Pol percent in the burnt was not significantly different from the two green harvesting methods. The average yields of burnt and green harvestings were 83 t/ha and 74 t/ha respectively. Finally, green harvesting increased Pty.   Discussion The results of this study show that in green cane harvesting, as compared with burnt cane harvesting, the trash is increased and the yield is decrease. Because the trash prevents the recovery sugar, we expected that quality indices in green cane harvesting to be worse than burnt cane harvesting. However, due to having fresh cane in green cane harvesting, the parameters of quality, especially the purity, were higher than those in burnt cane harvesting. In the executive phase, the difference between the green and burnt harvesting is more than this experiment because a cane field that has been burnt for harvesting is usually detained for more than 12 hours for transporting the cane to the factory, resulting in much lower quality. The benefits of green cane harvesting will better be understood now if the trash is decreased in green cane harvesting by setting and changing the harvesters.

Iran is a land of seven thousand years old civilization, one of the oldest civilizations of the ancient world, because of its rich cultural and artistic history, there are many monuments, most of which are in high seismic danger areas. Bam Citadel was built in the 5th century BC and covers an area of 180,000 square meters was located on the Silk Road, one of the world's largest adobe structures. The superstructure and valuable damaged during the earthquake and unfortunately it was destroyed more than 80 percent. In other words, one of the lessons that can be learned from the Bam earthquake is that the historic adobe structures are extremely vulnerable. Therefore, due to its rich history and rich artistic heritage including architecture, masonry and pottery, the need to preserve remains of the past is felt more and more. In this article, after highlighting the importance and necessity of preserving historic adobe structures, their architectural features are discussed. The next step will be discussed the seismic performance of historic adobe structures and methods of the seismic retrofit and restoration of them investigated. Finally, studies on the retrofitting and restoration of adobe structures will be reviewed.

Hot potassium carbonate (PC) solution in comparison with amine solution had a decreased energy of regeneration and a high chemical solubility of . To present vapor and liquid equation (VLE) of this system and predict  solubility, the ion specific non-electrolyte Wilson-NRF local composition model (isNWN) was used in this study; the framework of this model was molecular. Therefore, it was suitable for both electrolyte and non-electrolyte solutions. The present research employed the NWN model and the Pitzer-Debye-Hückel theory in order to assess the contribution of the excess Gibbs energy of electrolyte solutions in a short and long range. The data of  solubility in water and the system of aqueous  were correlated in the model considering a temperature range of  and a pressure range of and . The average absolute error of ( ) and ( ) systems were  and  respectively. The results and comparisons with other models proved that the experimental data were exactly correlated in the model.

Organizational culture is one of the important predictor of organizational effectiveness, and a key factor success of the organization as a competitive advantage. Todays, a continuous assessment of organizational culture status is considered essential; therefore, this study aimed to identify and measure organizational culture of the Ministry of Health and Medical Education. This descriptive-analytical study was conducted on the headquarters of the Ministry of Health and Medical Education in 2017. The study population consisted of all employees of the Ministry of Health and Medical Education (N=2200), 327 personals were selected through Cochran formula and stratified sampling method. The data collection instrument was a researcher-made questionnaire whose validity and reliability were confirmed (Cronbach's alpha =86.5%). In order to data analysis SPSS24 using descriptive and inferential statistics tests were utilized. The mean score of total organizational culture was 3.30 ± 0.70 from 5 which was higher than the theoretical average. Also, there was also a significant difference in partnership dimension in terms of employment type and in participation dimensions, accountability to the upstream institutions as well as total organizational culture score in terms of deputy. There was a direct statistical association between dimensions of organizational culture. According to study results, strong organizational culture will lead to improved performance in the organization and alignment of individuals and activities. Given the importance of specific role of culture in each organization, plans success and change strategies, human resources managers should take appropriate actions to improve internal and external communication and increase teamwork and accountability.

Considering the key role of the Ministry of Health staff in developing major policies of the country and the importance of the health system employees in improving productivity and achieving the goals of the organization, the purpose of this study was to predict organizational commitment based on the dimensions of job satisfaction in the staff of the Ministry of Health, and medical education. This cross-sectional study was performed on employees of the Ministry of Health and Medical Education in 2017. Data were collected using Job Descriptive Index (JDI) questionnaire and Allen & Meyer Organizational Commitment. The data were analyzed using Pearson correlation coefficient and linear regression model. There was a significant direct correlation between job satisfaction and organizational commitment (r = 0.41). Also, the results of regression analysis showed that organizational commitment can be significantly predicted based on the dimensions of work satisfaction (B = 0.16) and promotion satisfaction (B = 0.12). The findings revealed that job satisfaction is associated with organizational commitment. It is suggested that human resource managers provide conditions for increased satisfaction and job motivation such as appropriate awarding based on the actual evaluation of performance and increasing salary according to the capabilities of the employees to improve organizational commitment of employees.

In this study, 4-(2-pyridylazo) resorcinol (PAR) as model azo dye was used. In spectroscopic measurements and studies of PAR reagent as a ligand are used to formation a complex with toxic metals. So, removal and degradation these compounds of wastewaters are necessary. The aim of this study is the degradation of PAR from aqueous solutions in circulating fludized bed photo reactor (CFBPR) using ZnO powder. The UV/O2 system was used for dye degradation. ZnO powder used a catalyst for the degradation of dye in aqueous solution. ZnO powder has been characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR). The effect of operational parameters such as: pH, catalyst dosage and temperature were studied. The effect of UV irradiation, UV/O2 and UV/O2/ZnO on photocatalytic degradation of PAR were studied. The reaction kinetic was studied. The optimum conditions were determined using design of experimental based one factor at the time (OFAT) method. The optimum conditions for this reaction were obtained at pH=10, catalyst dosage=20 mg/L, and temperature=40°C. The pseudo first order reaction with rate constant (k=0.0105 min−1) in T=40°C was observed for the photocatalytic degradation of PAR. Activation energy (Ea) for the degradation of PAR was obtained as 48.12 (kJ/mol). These experiments demonstrated that UV/O2 and ZnO catalyst were needed for the effective degradation of dye. The results showed that the photocatalytic process can be suitable to degradation PAR dye from aqueous solutions using ZnO catalyst.
