Study and analyzing the obstacles to achieving humanperfection in the Holy Qur'anAbstract:Human perfection is one of the important topics and goals of the Holy Qur'an. But we see that the Almighty God creates billions of people, but at any time, a small number of these innumerable human beings can be perfected and as a human being, which is the purpose of God for the sake of mankin. Therefore, the research question is what are the barriers to achieving human perfection. According to the research hypothesis, it seems that the barriers to achieving human perfection and their virtues have been expressed through numerous verses from the Quran. In this research, with descriptive-analytical method and library study and using interpretive and narrative resources, by examining the number of 110 Quranic verses, forty barriers were extracted as obstacles to achieving human perfection, and classified in the four groups of obstacles: belief, internal and physical, material and erotic, behavioral and social groups. Then analyzed by qualitative content analysis method and categorized in 11 groups according to the threats of verses. The findings of the research indicate a direct relationship between the severity of the barriers and the severity of the obstacles. Consequently, the barriers to belief are the most severe and most important threats, and thus the main obstacles. Forty obstacles, in fact, are forty hijab perfection that by overcoming one of these hijabs a person can complete a degree of perfection.

The purpose of the paper was to identify barriers to sports startups growth and provide solutions. The research was applied in terms of purpose and qualitative in terms of method, for which the Delphi technique was used. In order to collect data, library studies, interviews and finally the Delphi questionnaire were used. The statistical population of all professors of sports management, sports managers, sports entrepreneurs and specialists in science and Technology Park in Hamadan province was 45 people. The sampling method was purposive and 30 people participated in the study. Three rounds of Delphi were used. The results showed that among the obstacles to the growth of sports startups were; Managerial, socio-cultural barriers, lack of awareness and knowledge, legal barriers, human barriers and environmental barriers that were expressed in proportion to the strategies for the growth of start-ups. It seems that the strategies for the growth of sports start-ups, taking into account the entrepreneurial ecosystem and considering all the stakeholders involved in the sports community, provide favorable conditions such as intellectual property protection, low level of corruption, financial support, supporting research and development as well as improving access to finance can be beneficial to the continued growth of this type of business.

Persian oak (Quercus brantii) is a critical, economic, and environmental species of Zagros forests in Iran. The effects of climate change and drought have caused a decline in Persian oak populations, leading to a severe reduction in genetic resources for future conservation programs. This study aims to evaluate the diversity and population structure of Persian oak in the western forests of Iran using morphological features. A total of 187 samples were collected from 15 locations in the Ilam province. Twenty phenotypic traits related to leaf, seed, and trunk characteristics were evaluated. Several multivariate statistical analyses were performed. The results revealed significant morphological diversity among the Persian oak ecotypes. Correlation analyses revealed a significant positive correlation between leaf length attribute and distance from leaf base to maximum leaf width (0.55) and maximum width of the leaflet (0.64) traits. The leaf width at 50% attribute with the maximum width of the leaflet and distance from leaf base to maximum leaf width have a positive (0.8 and 0.51 respectively) and significant correlation (p≤0.05). According to principal component analysis, the components of leaf and seed traits have the most impact on morphological variance. Hierarchical cluster analysis divided the locations into two groups, with some oak locations distributed in two clusters, indicating higher diversity of this species in different locations. Further research is needed to determine the optimal ecotype; however, the oaks in Ghallaje region have characteristics that can increase their ability to resist water scarcity, making them potentially appropriate for reforestation in Ilam province.

Suaeda salsa is an annual halophyte with nutritional value and high salt tolerance, making it crucial as an oil, medicinal, and edible plant. Currently, there is limited research in the field investigating metabolic diversity in S. salsa. In this study, our aim was to understand the salinity tolerance mechanism by examining metabolic diversity, specifically the amino acids profile, in S. salsa exposed to 0 mM, 200 mM, and 800 mM NaCl. The results of the physiological study indicated that salinity significantly affected the sodium (Na+) content in the aerial parts of the plant, with a significant increase compared to the control. Principal component analysis (PCA) revealed that differences in metabolic diversity can explain 96% of the phenotypic variation in S. salsa under salinity stress. Comparison of amino acids profiles at different salinity levels showed the highest accumulation of proline, methionine, citrulline, and lysine under 800 mM salt stress. Given the crucial role of these amino acids in S. Salsa,further studies are necessary to uncover the mechanisms behind the adaptation response.

MicroRNAs are small RNAs known for their essential roles in regulating both biotic and abiotic stress responses. Drought stress poses a significant challenge to wheat productivity in Iran. The present study evaluated the expression of miR9863a and its target genes in wheat, as well as three Aegilops species under drought stress. The results revealed differential expression of miR9863a in the shoots of the studied plants under drought stress conditions. Specifically its expression was increased in Ae. tauschii and Ae. crassa, while decreasing in Ae. cylindrica. The observed differential expression could be explained by the inherent nature of miRNA as a mediator molecule in various biological processes. Analyzing the expression pattern of miR9863a and its target genes in Ae. tauschii suggests that the effect of miR9863a in response to drought stress may be attributed to PLGG1, impacting glycerate/glycolate transfers and SAR1A,  influencing trafficking of transcription factors from the endoplasmic reticulum to the nucleus. In addition to complementing previous studies on the role of miR9863 in countering plant diseases, the results presented here  illustrate how this miRNA assists the abiotic stress-response mechanism in plants, particularly in the context of drought stress.

Today, sustainable innovation is recognized as a way to gain a competitive advantage and solve social and environmental problems. The aim of this study was to developing a model of sustainable innovation in public hospitals in Tehran using Grounded Theory in public hospitals in Tehran. 

The present study is a qualitative study that was performed by Grounded Theory method. Experts of public hospitals in Tehran (physicians, hospital managers, deputy director of development and support and administrative assistants) were considered as the population of this study. A combination of targeted method and snowball was used to select the sample. The method of data collection was semi-structured interviews with 11 experts familiar with the topic of sustainability innovation. The validity of the instruments was determined by external audits and the reliability was determined by Holsti Test and the data were analyzed through open, axial and selective coding.

The model of sustainable innovation in hospitals was developed in 6 components, 25 subcomponents and 84 concepts. Subcomponents include: causal conditions such as political stability, economic stability, stability of laws and cultural stability, background conditions include internal environment dynamics, staff dynamics, vision and awareness dynamics, and infrastructure dynamics, intervention conditions include macro environment conditions, organizational conditions and capabilities, and infrastructure conditions, axial phenomena include environmental monitoring and management, social monitoring and management, economic monitoring and management, strategies include health-oriented, quality and up-to-date services, keeping pace with the Fourth Industrial Revolution, attention to design and architecture, crisis preparedness, bio-imitation and pollution management, outcomes were categorized into tangible community outcomes, intangible community outcomes, tangible hospital outcomes, and intangible hospital outcomes. 

The final model indicates that the 6 components, 25 subcomponents, can provide sustainable innovation in public hospitals. It is suggested that hospital officials, considering the model developed, provide a suitable platform for the development of sustainable innovation in hospitals.

Ferula.gummosa is one of the important medicinal plants in Iran and world. Today this plant is endangered in nature. One of the reasons for the threat is the long dormancy of galbanum seeds and its very low germination power, along with its uncontrolled harvesting. In this research, which was conducted in a completely randomized design with 3 replications and 3 treatments at the Biotechnology Research Institute of Zanjan University of Medical Sciences, galbanum plant embryos from Fars province were seprated from seeds and cultured to find the best concentration for growth in MS media with concentrations of 1/2-1/4 and complete MS media. After 30 days, traits such as seedling length, seedling weight, and percentage of germination in each medium were measured and compared. The results showed that the growth rate of this plant in MS1/4 media was higher than the two other concentrations . According to available published sources, the results of this study are reported for the first time on the effect of culture medium concentration on germination and seedling growth indices of Ferula.gummosa plant

Artificial seed technology is a novel method in biotechnology where artificial seeds are produced and encapsulated using various materials and processes. These seeds are typically created by encapsulating plant meristems or somatic embryos, using polymer materials such as sodium alginate for encapsulation. One of the advantages of these seeds is the easier and better cultivation of certain plants, especially those with harder germination conditions due to dormancy or environmental factors. However, the use of artificial seed technology comes with challenges, including environmental impacts, production costs, and technical issues such as improving encapsulation processes and the quality of artificial seeds. This article introduces artificial seeds and production methods, the materials used for encapsulation, the principles of encapsulation, the advantages, and challenges faced by these seeds. Some companies active in the field of artificial seeds and the plants from which artificial seeds are produced are introduced to further study and advance this technology.

The mercury-induced liver pathogenesis is mainly mediated by oxidative stress. The aim of the current study was to evaluate the possible ameliorative effect of harmine, a natural compound, on liver toxicity induced by mercury chloride (HgCl2).

Forty-two male Balb/c mice were randomly divided into six groups (n = 7): Control, HgCl2 (0.5 mg/kg), harmine (20 mg/kg), and HgCl2 (0.5 mg/kg) + harmine (5, 10, or 20 mg/kg). The mice received treatments once per day for two weeks. After this period, the blood and tissue samples were collected for analyses.

HgCl2 caused a significant increase in levels of hepatic enzymes alanine aminotransferase, aspartate transaminase, and alkaline phosphatase; while harmine ameliorated these effects. Harmine in HgCl2-intoxicated mice, showed protective effects as evidenced by the increase in liver relative weight to body as well as the diameter of central vein in the co-treated group. Serum levels of malondialdehyde and nitric oxide increased in HgCl2, while they were declined in harmine co-treated groups compared to HgCl2 group. The serum level of superoxide dismutase and total antioxidant capacity improved following harmine treatment in the co-administrated group compared to HgCl2 group. Moreover, gene expression analysis demonstrated that harmine treatment improved the HgCl2-induced decreasing of Ho-1, Nrf2, Hqo1, and Trx1. The histopathological examination confirmed the protective effects of harmine.

Mercury can induce toxicity by elevation of oxidative stress in the liver and harmine attenuates hepatic injury induced by HgCl2, at least in part, through its antioxidant activities.

This article compares the theories of the great Islamic and Western philosophers, professor Motahhari and Rousseau on social determinism. The purpose of this article is to clarify the differences or possible commonalities in their views on social determinism. Therefore, this research has used analytical-descriptive method, using library studies and examining the works of these two philosophers, to study their arguments and foundations. The research findings show Rousseauchr('39')s basics in the form of a triangle whose base is the originality of society. On the other hand, the principles of Motahari in the negation of social determinism are expressed in the form of five angles, in which the principle of nature has a fundamental role.

Capers (Capparis spinosa) are one of the valuable medicinal plants that can grow in a wide range of ecological situations. In order to investigate the effect of climate on the physiological compounds of this plant, plant samples were collected in late summer with three replications from the mountainous areas of Amol city (Nemarestaq, Delarestaq and Behrestaq) at four altitudes with a difference of 150 meters (minimum altitude 850 meters). Some physiological traits of leaves and fruits were measured and analyzed by compound analysis in a completely randomized design. Data analysis showed that all the measured traits were affected by climate and were statistically significant, so that the highest amount of chlorophyll a, chlorophyll b, carotenoids, vitamin C, phenol, flavonoids, anthocyanins, antioxidants at an altitude of 1650 meters in Behrestagh region with 6.75, 10.56, 3.59, 15.60, 24.66 mg/g fresh weight, 4.51, 2.55 μmol/g fresh weight and 81.78% inhibition, respectively, and the lowest was observed at an altitude of 850 meters in Nemarstagh area. Regression slope also proved the significant relationship between traits and region and altitude, and antioxidant capacity which is the most important medicinal property of this plant, along with chlorophyll a, had the highest relationship (r² = 0.93). Also, the analysis of Pearson simple correlation coefficients showed a positive and significant effect between the traits. In general, with increasing altitude, an increase in the amount of measured physiological compounds that have medicinal effects was observed, so it is possible to develop the cultivation of some medicinal plants close to this family in the highlands.

Plant flavonoids show positive responses to geographical changes, especially altitude, and considering that the medicinal plant of capper (Capparis spinosa) is ecologically distributed in different habitats, so in this research the effect of altitude on the content of anti-cancer flavonoids such as rutin and quercetin were studied in capper which sampled in summer from three mountainous areas of Amol (Nemarestaq, Delarestaq and Behrestaq) at four altitudes with difference heights of 150 meters from each other (minimum 850 and maximum 1650 meters) and with three replications in a completely randomized design. Total flavonoids, rutin and quercetin were measured and analyzed by spectrophotometry and HPLC. The results showed a significant difference between measured traits in different regions (p≤0.01 and p≤0.05), so that the highest amount of flavonoids, rutin and quercetin were obtained at an altitude of 1650 m in the third region (Behrestaq) with 4.51±17 μmol, 24.62±0.28 and 4.91±0.18 mg/g fresh weight, respectively. Therefore, zone and altitude had a positive effect on the amount of medicinal metabolites of capper. Also, the equation of regression lines and explanatory coefficients (r² = 0.91, r² = 0.74 and r² = 0.78) showed that the amount of flavonoids, rutin and quercetin at different altitudes in Nemarestaq, Delarestaq and Behrestaq increased with increasing altitude and the slope of the regression line for all traits was positive. Therefore, nature is the best model for obtaining more concentrated and desirable anti-cancer flavonoids in plants.

In order to investigate the relationship between quantitative traits and ISSR markers, an experiments were carried out under farm and laboratory conditions at Zanjan University. In this experiment, 20 primers of ISSR marker were used and the agronomic traits (including flower number, fresh weight of Stigma, fresh weight of flower, dry weight of Stigma, dry weight of flower, stigma length, saffron yield, corm number, feresh and dry weight of corm, number of leaf, leaf length, leaf width, leaf area, leaf dry weight, biomass, harvest index), physiological traits (transpiration rate, stomatal conductance, photosynthesis) and secondary metabolites (picocrocin, Safranal and Crocin) were measured during the growing season. Three primers of total did not amplified. 17 ISSR primers amplified 133 loci among 20 saffron ecotypes, with an average of 7.82 loci per primer. The highest number of alleles were for the I-8 primer (15 alleles).

In 1976, A. Lambert characterized subnormal weighted shifts. Then he studied hyponormal weighted composition operators on  in 1986 and in 1988 subnormal composition operators studied again by him. Recently, A. Lambert, et al., have published an interesting paper: Separation partial normality classes with composition operators (2005). In 1978, R. Whitley showed that a composition operator   is normal if and only if  essentially. Normal and quasinormal weighted composition operators were worked by J.T. Campbell, et al. in 1991. In 1993, J.T. Campbell, et al. worked also seminormal composition operators. Burnap C. and Jung I.B. studied  composition operators with weak hyponormality in 2008.

Each year a large amount of saffron petals which make up a significant proportion of saffron flowers are discarded as waste while this part of the flower also contains compounds such as phenol, anthocyanin, flavonoid and antioxidant properties. Two separate experiments were conducted using randomized complete block design with three replications in order to evaluate secondary metabolites, total phenol content and antioxidant capacity of petals in eight saffron populations under normal and once irrigation conditions  at the research farm of university of Zanjan on three year old saffron plants. In order to measure and determine secondary metabolites, total phenol content and antioxidant properties of saffron petal extract, UV-Visible  Metering Spectra, folin-Ciocalteu and DPPH were used, respectively. Combined analysis of variance under normal and once irrigation conditions showed that the difference between secondary metabolites and antioxidant properties was not significant in the two irrigation conditions. While, total phenol content was significantly higher under the once irrigation condition, the  Torbat-e-jam population had highest total phenol content (86.66 mg gallic acid per gram of methanolic extract) under this condition. In both irrigation conditions, the evaluated populations exhibited suitable amounts of picocrocin, safranal, phenol and antioxidant properties which can be considered to be of use for us in the food, pharmaceutical and chemical industries.

This investigation was carried out to determine the conversion and growth ability of artificial seeds derived from encapsulation of sunflower shoot tips in different substrates as factorial based completely randomized design with five replications, in tissue culture laboratory of Kermanshah Agriculture Research Center in 2013. Shoot tips excised from in vitro proliferated sunflower plantlets were encapsulated in three percent sodium alginate and 100 mM CaCl2.2H2O. Determination the effect of using nutrients and plant growth regulators, alginate matrix supplement with three different matrixes include distilled water, liquid MS medium and liquid MS medium whit tow mg/l BA and tow mg/l IAA. Synthetic seeds were transferred on hormone-free MS medium and two commercial substrates mixture of cocopeat, perlite (1:1) or cocopeat, perlite and peat moss (1:1:1) for generation and growth ability evaluation. Using of MS nutrients and plant growth regulators in calcium alginate beads significantly improved encapsulated explants growth. Maximum percentage response for conversion of synthetic seeds was 100 percent that was achieved from in vitro culture on MS medium and directly culture in ex vitro condition caused to decrease the conversion and growth them.

A sequence {T n } ∞ n=1 of bounded linear operators on a separable infinite dimensional Hilbert space H is called subspace-diskcyclic with respect to the closed subspace M⊆H, if there exists a vector x∈H such that the disk-scaled orbit {αT n x:n∈N,α∈C,|α|≤1}∩M {αTnx:n∈N,α∈C,|α|≤1}∩M is dense in M . The goal of this paper is the studying of subspace diskcyclic sequence of operators like as the well known results in a single operator case. In the first section of this paper, we study some conditions that imply the diskcyclicity of {T n } ∞ n=1 . In the second section, we survey some conditions and subspace-diskcyclicity criterion (analogue the results obtained by some authors in \cite{MR1111569, MR2261697, MR2720700}) which are sufficient for the sequence {T n } ∞ n=1 to be subspace-diskcyclic(subspace-hypercyclic).

In the present study, the effect of plant growth regulators on direct somatic embryogenesis and plant regeneration of two Iranian sunflower hybrids (Azargol and Farrokh) were examined. After the flowering, immature embryos ten day after pollination were used as explants. Immature embryos were surface sterilized and subsequently transferred to embryogenesis medium containing MS medium elements and B5 vitamins, 120 g/l sucrose and different combinations of plant growth regulators (BA in two levels,1 and 2 mg/l in combination with NAA or 2,4-D in three levels 0.1, 0.25 and 1 mg/l and 2,4-D in two levels, 0.33 and 1 mg/l. Analysis of variance showed significant differences between hybrids, hormones and hybrids×hormones interaction. The somatic embryos were first observed 10 days after culture on medium containing 120 g/l sucrose and a callus intermediate was not formed. Somatic embryos of two sunflower hybrids directly obtained on a medium supplemented with 2 mg/l BA and 0.25 mg/l NAA with more number and speed.

The present study demonstrates the potential of nutrient-alginate encapsulation of shoot tips of sunflower, Helianthus annuus (hyb. Azargol) for synthetic seed technology, which could be useful in germplasm distribution and exchange. Shoot tips from in vitro shoot cultures derived from mature seed explants were encapsulated in 3% sodium alginate and 100 mM CaCl2. 2H2O are supplemented with three different matrices (include distilled water, liquid MS medium and plant growth regulators) and they are stored for several periods (15, 30, 45 and 60 days) at 4°C. After each storage period for regeneration and regrowth evaluation, encapsulated and non-encapsulated shoot tips were cultured on hormone-free MS medium. The regrowth ability of encapsulated shoot tips affected by the storage duration and the presence or absence of MS nutrients in calcium alginate beads. Percentage response for the conversion of encapsulated and non-encapsulated shoot tips decreased gradually after storage at 4°C by increasing storage durations. Indeed, encapsulated vegetative propagules showed a higher resistance to storage at 4°C than non-encapsulated. Addition of MS nutrients in calcium alginate beads significantly improved encapsulated explants regrowth after storage periods.

Synthetic seeds can use as tool for applied biotechnology methods for improve the quality and increase the production of sunflower. Shoot tips excised from in vitro proliferated shoots were encapsulated in calcium alginate beads. The best gel complexation was achieved using 3% sodium alginate and 100 mM CaCl2.2H2O. Maximum percentage response for conversion of encapsulated shoot tips into plantlets was 100% after 4 wk of culture on Murashige and Skoog (MS) medium without plant growth regulators. The regrowth ability of encapsulated shoot tips was affected by the concentration of sodium alginate and the presence or absence of MS nutrients and plant growth regulator in calcium alginate beads. Plantlets with well-developed shoot and roots were transferred to pots containing an autoclaved mixture of cocopeate¡ perlite and peat moss (1:1:1). Encapsulation of vegetative propagules in calcium alginate beads can be used as an alternative to synthetic seeds derived from somatic embryos.

In order to investigate the effective traits on yield of saffron ecotypes, a study was carried out as a split plot in time based on randomized complete block design with three replications in the research farm of Zanjan University during the growing seasons of 2013-2015. Eighteen saffron ecotypes were studied in this experiment. The traits of number of flowers, fresh weight of flowers, fresh weight of stigma, dry weight of flowers, dry weight of stigma, stigma length and dry stigma yield of saffron were measured. The results indicated that there were significant differences among all studied traits of ecotypes except for stigma length. The correlation matrix revealed that the number of flower and dry weight of stigma had a positive and highly significant correlation with dry stigma yield (r= 0.99 and 0.70, respectively). Analysis of stepwise regression and path analysis showed that the traits of number of flowers, dry weight of stigma and dry weight of flowers were the most effective traits on dry stigma yield. Therefore, these traits can be used to achieve a higher stigma yield.

Water shortage is one of the most important environmental factors in limiting plant production worldwide. Molecular breeding may help to develop drought tolerant plants. Proteomics approach can help in comprehensive analysis of stress responsive genes and identification of drought signaling pathways. These drought tolerance candidate genes or their regulatory genes may be further analyzed for their possible implication in increase plant tolerance to drought stress. In this studied we analyzed the changes in proteome of wheat flag leaf in response to drought. We compared a drought tolerant with drought susceptible genotypes under normal and stress well-watered and stress conditions. Stressed plants were exposed to 50% field capacity before anthesis. Out of 900 proteins analyzed across two dimensional gels، 57 protein spots showed significant differences in response to stress. Of these، 42 protein spots could be identified using mass spectrometry analysis. Differentially expressed proteins and enzymes could be grouped in different functional groups. Our results showed that tolerant genotype may use various mechanisms particularly the up-regulation of genes involved in oxidative stress defense in flag leaf. This may help the tolerant genotypes to better remove reactive oxygen species generate by stress in flag leaf and maintain its physiological and photosynthetic activities.

Growth and metabolism of plants are affected by a variety of stimuli، including biotic and abiotic environmental stresses that could leads to responses of the plant through hormone regulation. miRNAs، are a group of Non-coding RNAs that some of them are involved in signaling of plant hormones. In this study، the expression patterns of miR159a،b، miR160، miR167a،b and miR171a have been studied in both drought susceptible and drought tolerant varieties in wheat using qRT-PCR. miR159a،b، miR160، miR167a،b and miR171a could play important roles in MYB، ARF، ARF، and SCL، transcription factors regulation، respectively. High conservation among the studied miRNA families was observed in the mature miRNA producer regions by multiplex alignment of pre-miRNAs. Results of qRT-PCR analysis indicated that expressions of miR160 and miR167a،b in tolerant Variety and miR159a،b in susceptible Variety are increased significantly. However، no significant changes in expression were observed for miR171a in both tolerant and sensitive varieties. Presumably، up-regulation miR159a،b in susceptible variety could be resulted to reduction in the expression of MYB genes involved in drought response. On the other hand، up-regulation of miR160 and miR167a،b in tolerant variety، may lead to regulation of auxin and abscisic acid pathways interaction and probably these miRNAs could contribute in stress tolerance in tolerant variety. In addition، no significant change in miR171a expression demonstrated that expression of SCL could be regulated through other mechanisms in plant.
