Abstract: 

Irrespective of their whereabouts, their cultural era, humans share COMMON gifts and potentialities arising from their epistemological existential essence. A large part of peoples’ knowledge and experiences are COMMON despite their differences in terms of culture, time, place and personal experiences. The important point is that this difference is only external, the underlying structure or deep structure is similar, since human potentialities are rarely influenced by cultural differences hence there exists similarities between Plato, Suhrawardi, Mowlana and Jung regarding the structure of the world and Man’s psyche in terms of deep structure.By presenting Plato’s world of illusion and Suhrawardi’s world of image, Zoroaster’s spiritual divine forms (farvahar), Jung’s collective unconscious, and the sayings of Attar and Mowlana regarding divine eternal self, one can clearly find resemblances in terms of deep structure between these modes of thoughts.

Abstract: 

In order to study the genetic control of resistance to COMMON smut in maize, two resistant inbred lines, K1264/1 and K47/2-2-21 and two susceptible inbred lines, K3304/1-2 and K47/2-2-1-3-3-1, were crossed as K1264/1 × K3304/1-2, K47//2-2-21 × K3304/1-2 and K1264/1 × K47/2-2-1-3-3-1. The F1, F2, BC1 and BC2 progenies were produced and evaluated along with parents using randomized compelet block design with three replications. All generations were artificially inoculated with spordia of Ustilago maydis suspension. Inoculation was carried out 7-10 days after silking through injection of 3 ml of 106 spores/ml fungal suspension, using tip injection method. At maturity, disease severity was determined based on ears infection and analysed according to generation means analysis method for three crosses. Joint scaling test showed that the presence of additive, dominance and epistasis effects, especially additive × additive and dominance × dominance type, and in lesser extent, additive × dominance, in genetic control of resistance to maize COMMON smut. Average broad and narrow-sense heritability based on three crosses data were estimated 80.3 and 57.3, respectively.

Abstract: 

The use of zeolite was investigated to improve the environmental condition of COMMON carp. The fingerlings of 13 grams were tested in 4 treatments. Each treatment contained 60 fish and 3 replications, in RBD experiment design. The treatment was performed 20, 40, 80 and 120 mg/l and one without zeolite as control. EC, T, O2 and salinity was equal but the amount of No2, NO3, NH4 and total hardness, was lower in zeolite treatment compared to the control group. Other parameters such as TDS, pH and sulfide were not different. The results showed that using zeolite can improve the water condition but the SGR, PER, FCR and total weight, in spite of pronounced difference between the dosage of 8 and 120 mg/l, the difference was not significant. In treatment of 80 mg/l, weight increased for 31%, GR for 29%, SGR for 29%, PER for 42%, more than the control group. FCR in the control group was 3.07 while in treatment with 80 mg/l zeolite, it was 2.34.The present study showed by using zeolite and by good management to improve the water condition, it is possible to improve the growth parameters of fish.

Abstract: 

Background: Lactofermentation by probiotics would help valorize ENUS (edible neglected and underutilized species). Probiotic lactic acid bacteria (LAB) are considered as vectors of molecules of nutrition-health interest. This study has isolated and screened Lactobacillus plantarum strains with potential probiotic APTITUDES from neglected edible vegetableand fruits of Côte D’ivoire.Methods: Three L. plantarum strains (Pa6, A6, and Pe3) isolated from Ivorian ENUS (passion fruit, garlic and parsley) were isolated and screened for potential probiotic APTITUDES from neglected edible vegetable and fruits of Côte D’ivoire.Results: The screening of three strains revealed that they presented interesting probiotic potentialities (hydrophobicity values higher than 65% and pH=2, 0.3% bile salt, antibiotic and intestinal microbial pathogens resistances, respectively). They also presented antioxidant (14.51±0.39-39.48±0.88%), anti-inflammatory (8.88±00.00% 78.61%±00.00%) and exopolysaccharide APTITUDES, respectively. They synthetized degradinganti-nutritional- factor enzymes (phytase and tannase) and cell-walldegrading enzymes (amylase and cellulase). They fermented the indigestible sugar raffinose, survived at 6.5% NaCl for Pa6 and Pe3, pH=9 and 45°C for Pe3.Conclusion: These strains with such interesting technological properties would be suitable for industry in general, and particularly as starters for the controlled fermentation of Ivorian ENUS.

Abstract: 

Background and Aim: Teachers experience more mental health problems due to teaching-learning activities compared to other employees. Optimum use of talents can reduce job stress and prevent teachers from psychological damage. Therefore, the current research was conducted with the aim of designing a model of using talents and its role in the mental health of teachers of primary schools in Ardabil city. Materials and methods: The present research was conducted with a qualitative-quantitative mixed method. In the quantitative stage, among the 1632 elementary school teachers in Ardabil, 320 people were selected using Morgan's table by multi-stage and stratified sampling method, and the questionnaire was distributed among them. The statistical population of the research in the qualitative phase was an elite group consisting of principals and teachers sampled in the last three years, experts in elementary education, and 20 of them were interviewed with the purposeful sampling method and in terms of theoretical saturation. After analyzing the qualitative data, a researcher-made questionnaire of 46 questions was compiled, which was confirmed by the supervisors and advisors, and the combined reliability, Cronbach's alpha and AVE were obtained as 0. 78, 0. 84 and 0. 58, respectively, which shows that It has good reliability (values ​​above 0. 7, 0. 7 and 0. 5 respectively are considered strong for these indicators). Quantitative data were analyzed using structural equation method in Smart PLS2. Results: The findings of the research showed that the components of talent utilization include provision of talented human resources (Beta=0. 371, T. valu=2. 842), intelligence of goals (Beta=0. 418, T. valu=5. 702) and training facilities (Beta=0. 348), T. valu=3. 440) have a positive and significant effect on the deployment strategy of talent management, and the talent management deployment strategy (T. valu=36. 624, Beta=0. 862) has a significant effect on teachers' mental health. Conclusion: According to the results of the research, the use of talents by attracting talented and interested people and by applying the necessary strategies and contexts can have a very important effect on improving the mental health of primary school teachers. Therefore, the authorities can protect the mental health of teachers by paying attention to the effective components in using talents and removing obstacles and facilitating things.

Abstract: 

This paper is proposed a novel topology of a single phase grid connected inverter in order to conquest the COMMON mode leakage current. There are many topologies presented so far, But none of them has the efficiency more than 98 percent. In this paper, a modern configuration is presented that, not only delete the COMMON mode leakage current, but also increase the efficiency and power density and is affordable. this inverter consists of 6 switches and 2 diodes that in compare with similar ones, it has less element number. Than the famous topologies like H5, H6 and HERIC, the power loss and voltage stress on switches are decreased. These aspects are appears due to exclusive leg configuration and the placement of switches and diodes. The freewheel path revealed, decoupled DC side from AC side of Inverter which results in disconnecting the COMMON mode current. This issue will modify the network reliability indices and maintain safety standards. Finally the performances of proposed inverter will be compared and evaluated with some available Inverters.

Abstract: 

Eco-innovation is an actual topic as it links two key issues, innovation and sustainability. The environmental respect and innovation are important drivers of competitiveness. Firms are willing to know what to do to improve their eco-innovative capacity. The objective of this paper is to empirically determine what COMMON characteristics have the most environmental oriented innovative firms. We analyze data retrieve from the Spanish Technological Innovation Panel (PITEC) from 7682 Spanish firms using a two step approach. Results show the impact of certain variables in determining the environmental orientation of companies. More specifically, process and product orientation while innovating was reveled as crucial aspects in determining the environmental orientation of firms. Moreover, results showed the lower relative impact of the importance of market, institutional and technical information sources. Based on these results, we can determine which company’s behavior has to be promoted to get companies focused on environmental aspects. Important managerial and policy making implications are derived from the study.

Abstract: 

Background: COMMON variable immune deficiency (CVID) is the COMMONest symptomatic primary immunodeficiency and represents a heterogenous collection of disorders resulting mostly in antibody deficiency and recurrent infections. The syndrome includes impaired B-cell maturation, impaired somatic hyper mutation, reduced numbers of circulating memory and isotype-switched memory B cells, and absent or reduced plasma cells. B cell maturation antigen (BCMA) is a tumor necrosis family receptor superfamily member 17 (TNFRSF17), expressed only on B cell lines, and is essential for survival of long-lived plasma cells. The aim of this study was to evaluate mutations in BCMA in patients with CVID in compare with normal individuals in Isfahan, Iran.Methods: Blood samples were collected from 10 CVID patients with substitutive immunoglobulin therapy before immunoglobulins (Ig) infusion and 10 normal controls in ethylenediaminetetraacetic acid (EDTA) tubes then DNA samples were extracted and after the polymerase chain reaction (PCR) was done, samples were sequenced.Findings: After reviewing the results of the sequence and alignment of the sequences, no mutations in the gene were seen.Conclusion: In addition to the study of mutation in BCMA gene, BCMA gene and protein expression level should be considered to understand more aspects of this disease.
