The overall purpose of this study is to identify the dimensions and components of good governance in macro medical universities in region one. This applied study was conducted with a qualitative and quantitative approach. In the qualitative section, the statistical population consisted of 14 people who were selected by purposive sampling method based on the saturation law. Classified according to Cochran's formula were selected as the sample. A researcher-made good governance questionnaire with 64 questions in 8 dimensions was used to collect data. The validity and reliability of the instruments were confirmed by the supervisors and consultants and the combined reliability and Cronbach's alpha were calculated higher than 0.7. Exploratory factor analysis and confirmatory factor analysis were used to analyze the data. The results showed that good governance has 8 dimensions of university internationalization, accountability, university perspective, academic freedom, teamwork, foresight, transparency and university structure, the most important dimension of which was university internationalization.

The general objective of the present study was to evaluate the impact of good governance with the fourth-generation university development approach on the educational quality in macro medical universities of region 1.

Methods and Materials:

 This applied study was conducted with a mixed approach using a qualitative and quantitative approach in 2020. In the qualitative section, the Delphi method was used, and in the quantitative part, the descriptive survey method was applied. In the qualitative section, the statistical population consisted of 14 people who were selected by purposive sampling method based on saturation law, and 1851 faculty members of macro-medical universities in region one were in the quantitative section of whom 320 were selected as a sample using stratified random sampling method based on Cochran's formula. In order to collect the data, three questionnaires on good governance with the development approach of fourth-generation universities with 64 questions in 8 dimensions and Sadeghi et al.’s (2015) educational quality questionnaire with 53 questions in 6 dimensions were used. The face and content validity of the tools were approved by the supervisor and the consultant and the composite reliability and Cronbach's alpha were calculated above 0.7. SPSS21 and PLS3.2 software were used to analyze the data.

The results showed that good governance with the development approach of fourth-generation universities had 8 dimensions of university internationalization, accountability, university vision, academic freedom, teamwork, foresight, transparency, and university structure, the most important dimension of which was the internationalization of the university. The path coefficient was 0.662 and the value of R2 was equal to 0.438.

The results showed that the impact of good governance with the development approach of fourth-generation universities on educational quality with coefficients of 0.355 was positive and significant.

Moisture and water transfer into concrete can be considered as a major threat to the durability of concrete. Damp-proofing admixtures like calcium stearate (CS) can provide a water repellent layer along the capillary pores. As a result, water and moisture transfer into concrete will be restricted by means of this layer. Accordingly, this research studied the effects of CS on the properties fresh and hardened self-consolidating concrete (SCCs). The evaluation of fresh concrete properties demonstrated that the density of fresh SCCs, passing and filling ability were reduced due to incorporation of CS. Moreover, reduction in density and compressive strength of the hardened concrete can be deemed as the major impacts of CS on mechanical properties of SCCs. In fact, the last-mentioned parameters were decreased by respectively 4% and 30% due to inclusion of 7kg/m3 CS. Furthermore, utilizing CS can not be taken into account as a constructive approach to improve the durability chracteristics under hydrostatic condition. Because no considerable improvement can to be detected in the results of electrical resistivity and rapid chloride migration tests. Eventually, CS drastically enhanced the permeability of the concrete under non-hydrostatic condition. To be more precise, addition of   7kg/m3   of CS decreased the final depth of capillary water absorption, short and long-term water absorption by respectively 60%, 65% and 15%.

The effect of seed quality on field performance of lentil under different irrigation treatments was investigated in 2010 at the Research Farm of the University of Tabriz، Iran. A sub-sample of lentil seeds was kept as control or high quality seed lot (V1 with %99 viability) and two other sub-samples with about 15% moisture content were artificially aged at 40°C for 18 and 22 days (V2with %90 and V3 with %80 viability، respectively). So، three seed lots with different levels of deterioration and quality were provided. Laboratory tests were carried out as CRD to determine electrical conductivity of seed leachatesand germination percentage. However، the field experiment was arranged as split-plot based on RCB design with three replications. Irrigation treatments (I1، I2، I3 and I4: irrigation after 70، 100، 130 and 160 mm evaporation from class A pan، respectively) and seed lots (V1، V2 and V3) were allocated to main and sub-plots، respectively. The results showed that electrical conductivity of seed leachates increased، but percentages of germination and emergence decreased with increasing seed deterioration. Days to flowering، plant height and number of branches per plantwere decreased as water supply reduced. Plants from vigorous seed lot (V1) were higher than thosefromlow quality seeds، but plants from low vigor seeds (V3) had more branches، due to low density. Plants from high quality seed lotproduced the highest grain yield per unit area. Therefore، it was concluded that cultivation of high quality seeds (V1) can increase lentil yield by improving seedling establishment.

Energy diplomacy as an offshoot of economic diplomacy plays an important role in the contemporary global economy and has been one of the most important issues for politicians in different countries. Iran، as an actor in energy field with active and strategic role-playing in Gas Exporting Countries Forum، is seeking its own political and economical interests. The main purpose of this article is to appraise Iran’s success in achieving its own goals in Gas Exporting Countries Forum. The present study aims to evaluate Iran’s attempts to establish Gas Exporting Countries Forum and whether this forum can help Iran achieve its goals. The articles’ assumption is that the possibility of Iran’s success in achieving its goals in Gas Exporting Countries Forum is trivial due to regarding the disagreement in the goals of the important countries in this forum and Western pressures، especially those of the U. S.، against Iran، on the one hand، and Iran’s internal needs (household consumption and oil industries)، on the other.

The effect of seed deterioration on seed emergence and seed yield of two oilseed rape cultivars (Licord and Okapi) was investigated in a factorial experimentation based on an RCB design with 3 replications in 2008 at the Research Farm of the Tabriz University, Iran. A sub-sample of seeds of each cultivar was kept as control (V1 with 98% viability) and two other sub-samples of Licord and Okapi with about 15.5% moisture content were artificially deteriorated at 40°C for 9 and 12 days, and for 7 and 10 days, respectively, (V2 and V3 with 85% and 71% viabilities, respectively). The highest percentage of seedlingemergence was obtained for the high quality seed lot and decreased with decreasing seed lot viability. Although grain yield per plant for plants from deteriorated seed lots (V2 and V3) were higher than those from high-viability seed lot (V1), but these advantages in individual plant performance were not sufficient to compensate for low stand establishment as indicated by 26.18% and 49.75% loss in grain yield per unit area for plants from V2 and V3 seed lots, respectively. Consequently, grain yield per unit area significantly improved with increasing seed vigor and viability of oil seed rape cultivar.

SUMMARY:

A 24 hour urinary calcium was measured in 21 healthy women and 32 healthy men. There were 20 evaluated once, 30 twice, and in 3 cases, urine collections were repeated 3 times. Oral calcium intake and urinary creatinine over 24 hours were also measured. The mean urine calcium in women was 126 mg/24 h and the range was 45-225, in men the values were 171 and 65-246.Oral daily calcium intake was 655 and 834 in women and men, respectively. The mean of 2 urine calcium determinations exceeded 200 mg/24 h in only one woman and more than 250 in none of the men. Our conclusion is that: 24 hour calcium intake and excretion in healthy individuals are lower than those values in Western countries, probably due to dietary deficiencies of meat and dairy products and decreased exposure to sun. We also concluded that in two different urine collection, women who excrerte more than 200 mg and men who excrerte more than 250 mg calcium are probably hypercalciuric subjects.
