The prominent role of HIF1α gene in adaptation to aerobic exercise has been confirmed. So far, there is no accurate information about the genotypes of this gene, so the aim of the present study was to determine and investigate the amount of changes in maximum oxygen consumption in response to aerobic exercise among carriers of different HIF-1α genotypes.

The present semi-experimental study of developmental and applied type was conducted in 2021. The studied samples were 23 inactive overweight women (height 157 ± 2.8 cm, weight 74 ± 1.8 kg, age 38 ± 5.4 years, body mass index 32 ± 2.4 kg/m2, selection and They participated in 8 weeks of aerobic training including 5 sessions per week and each session lasting 30 minutes with increasing intensity (55-75% of maximum heart rate). Before and after the training period, aerobic power (VO2max) was measured through the Bruce test. Sample Saliva was collected from all the subjects within 24 hours and sent to the laboratory to determine the genotype. The subjects were divided into two genotypic groups, including CC and CT. The collected data were analyzed using Levin's and independent t-tests at the 95% confidence level. became

The findings indicated that the aerobic capacity of CC and CT genotypes of HIF1-α gene increased. No significant difference was observed between the two genotype groups (p=0.079 and p=0.544). Although to some extent, the average value of changes in aerobic power of CT genotype after 8 weeks of aerobic training was higher than the other two genotypes, but this difference was not significant.

Eight weeks of aerobic training led to an increase in aerobic capacity in inactive obese women, and in this regard, the increase of HIF1-α followed by the induction of hypoxia plays a role. However, it does not seem that there is a difference between the different genotypes of the gene. HIF1-α is present in these changes.

Agroforestry has been implementing for a long time in Zagros forests. Understory cultivation of Cultivating perennial plants (such as Ferula assa-foetida) rather than annual plants (such as Triticum spp) may help to reduce the soil loss. This research aims to evaluate the financial profitability and soil loss resulting from two alternative agroforestry practices of forest-asafoetida and forest-wheat in Tang-sorkh region of Kohgiluyeh and Boyer-Ahmad Province. Financial analysis was performed using a cash flow diagram, land expectation value (LEV), equivalent annual value (EAV) and annualized return on investment (ROI) criteria. The annual soil loss was calculated using a universal soil loss equation based on rainfall erosivity, erodibility, the length, and the slope of the land, as well as the type of vegetation management. The soil conservation data were collected and measured in landform units. The soil samples were collected at (0-30cm) and (30-50cm) of landform units within the agroforestry practices areas. Economic information was compiled using the farmers' census method and the semi-structured questionnaire. The results showed that the annualized ROI in the forest- Asafoetida practice (32.6 %) is by far much higher than forest-wheat practice (-7 %). In addition, the results indicated that the average of soil erosion in forest-wheat practice (18.5 t ha-1 yr-1) is 6.6 times higher than the forest-assafoetida practice (2.8 t ha-1 yr-1). Future research will explain why farmers continue to apply loss-making forest-wheat practice.

The objective of this research was to train and develop from a professional perspective. Qualitative research and focus group techniques were applied in order to achieve this. Indeed, the first step was to study the literature on professional development by researching databases, library resources, high-level documents, and domestic reports. Afterwards, by holding focus group interviews and consulting with the participants who were experts, a professional education and development plan was designed. The research statistical population (both of academy and bank) included 12 experts who were well acquainted with Human Resource Development in banking industry. Data collection instruments involved interview protocols and questionnaires which were analyzed by the application of a content analysis method. Research findings included identification of job competencies at the level of branch, i.e. bank manager, deputy, chief officer, bank-teller, and caretaker, by applying a model which included both the individual and the organization and aspects of personality, viewpoint, knowledge, and skill. Through application of this two-dimensional model and four-field approach, educational modular courses were developed for each job in accordance with the level of competency required, perceptional, human, or technical. The findings of this research indicated that in order to develop branch managers and staff professionally in monetary and banking fields, competency-based training programs focusing on required skills for each position should be developed. For instance, in modular courses to be attended by the managers and deputies, management and perceptional skills should be highlighted; whereas in case of bank-tellers a more emphasis was put on job competencies and technical skills.

In this paper, we investigate the relation between L-projections and conditional expectations on subalgebras of the Fourier Stieltjes algebra B(G), and we will show that compactness of G plays an important role in this relation.

Ice cream, a milk based product is a good media for microbial growth due to high nutrition value, almost neutral PH value and long storage duration. Contamination of this product with pathogen micro-organism can lead to food poisoning and food born infection and can endanger the sanitation of human. The aim of this research was to assess microbial status of traditional Ice creams.

In this cross-sectional study a total of 100 samples of traditional Ice cream were obtained randomly from the retail stores in summer. All the samples were analyzed for microbial contamination according to the Iran national standard. The collected data were analyzed statistically using t-test by SPSS for windows.

The results show that 26% of the samples were contaminated higher than standard level (>5×104 /gr), 75% of the samples were contaminated higher than standard level (>10 /gr) with entrobacteriacea. staphylococcus aurous and Escheria coli were isolated from 4% and 32% of samples respectively. No salmonella was isolated from samples.

To prevent out break of poisoning and microbial infections due to consumption of Ice cream as well as supervision and control during the production are essential.
