In the open coding, the researcher identified 41 concepts. Then, based on the initial raw data, preliminary categories related to the phenomenon under investigation were formed by breaking down the information, structuring categories of information about the studied phenomenon, questioning the data, comparing cases, events, and other states of phenomena to identify similarities and differences, which were categorized into 5 categories: 1) acceptance of high investment costs, 2) acceptance of instability in the business environment, 3) lack of trust in the market, 4) acceptance of sudden changes in domestic markets, and 5) emotion management. This systematic evaluation can help a trader correct mistakes, change bad habits, and improve overall returns. Investors need to be quick, be aware of their greed and fears, and also be able to act flexibly. As it is evident, for any trading, it is necessary to be aware of personal and market psychology beyond specialized trading knowledge.

There are widespread concerns about the potential toxic effects of microplastics as emerging pollutants. The current research investigated the impact of polystyrene nanoplastics on the growth performance, survival rate, liver enzymes activity and the immune gene expression of IL1 and IL8 genes in zebrafish (Danio rerio). Fish were divided into four treatments and fed with diets containing 0 (control), 100 (treatment 1), 500 (treatment 2) and 1000 (treatment 3) mg/kg diet for one month. The present study results showed that weight gain (WG) and specific growth rate (SGR) were affected by the experimental treatments, and with increasing concentration of polystyrene nanoplastic, they decreased significantly (P<0.05). The best food conversion ratio (FCR) was obtained in control and treatment 1 (P<0.05). No mortality was observed through different treatments. The highest activity of alanine aminotransferase) ALT(, alkaline phosphatase) ALP(, and aspartate aminotransferase )AST( was observed in treatment 3 (P<0.05). The highest level of IL1 and IL8 gene expression were measured in treatment 3 and the lowest level was seen in control (P<0.05). In conclusion, the results of this research showed that a diet containing polystyrene nanoplastics had a negative effect on the growth (WG and SGR) and health indicators of the fish and the greatest disturbance in the growth and health of fish were observed in high concentrations.

Breast cancer is the most common form of cancer in women, and the second leading causes of death in the world. Clinical efficacy of chemotherapy is limited due to side effects, toxicity, and drug resistance. Plant-derived anticancer drugs are new promising compounds, which show their anticancer activity through activation of apoptotic pathways. Ginger is a flowering plant with active phenolic compounds that exhibit anticancer activity. Here we studied the effect of ginger acetone, ethanol and methanol extracts on the MCF-7 breast cancer using MTT assay, Real time-PCR and normal inverted microscope. MCF-7 breast cancer cells were incubated with 2.5, 5 and 10 μg/mL of ginger extracts for 48 h. The survival of incubated MCF-7 cells with ginger extracts, indicated significantly decreased. The most dramatic effect was noted in cells incubated with acetone extracts, 10 μg/mL for 48 h compared to the control. Moreover, by increasing the concentration of ethanolic ginger extract, the cell vitality decreased significantly. Real-time PCR results showed that the expression of Bcl-2 was significantly decreased in cells incubated with ginger extracts. Decrease of Bcl-2 expression can cause increase apoptotic pathways and reduction of cancer cell survival. Thus, extract of ginger destroys breast cancer cells and other cancers cells and improves health.

The cytotoxicity studies of gold nanoparticles by MTT on the breast cancer cell line (MCF-7) showed Ic50 of gold nanoparticles of 24.1. Therefore, these nanoparticles are capable of inhibiting the activity, growth and proliferation of cancerous cells at low concentrations

In today's tense world, the existence of a strong and effective military force is considered as the strategic asset of every nation. Meanwhile, designing and updating military equipment and increasing their reliability and durability are particularly important. On the one hand, the mathematical model of optimization of military equipment at the design stage, due to the complexity and high volume of computing is in the Np-hard problems group, and requires meta-innovative methods for solving, and on the other hand it is in the multi-objective problem group, thus requiring the use of multi-objective methods. But the growing development and variety of multi-objective meta-innovative methods have challenged the choice of the appropriate algorithm in solving the aforementioned model. Therefore, the present study aims to review the modern algorithms, as well as provide a suitable method for solving the problem of military equipment optimization with the help of the sample. Thus, the necessity of mathematical modeling in optimizing the design of military equipment problem and the study and selection of the appropriate solution are the main goal of this research. In this applied- experimental study four algorithms (NSGA-II, MOPSO, PESA-II and MALO) were investigated and results with the help of six different indices were analyzed and evaluated. Meanwhile, combination of Hierarchical Process and Entropy Analysis (AHP-Entropy) approach were used to weigh the indices and the PROMETHEE method was used to evaluate the algorithms. The results emphasize the importance of the "Runtime" and "Pareto Response number" indicators on the priority of the MOPSO algorithm in solving the research problem.

Bi-objective optimization of the availability allocation problem in a series–parallel system with repairable components is aimed in this paper. The two objectives of the problem are the availability of the system and the total cost of the system. Regarding the previous studies in series–parallel systems, the main contribution of this study is to expand the redundancy allocation problems to systems that have repairable components. Therefore, the considered systems in this paper are the systems that have repairable components in their configurations and subsystems. Due to the complexity of the model, a meta-heuristic method called as non-dominated sorting genetic algorithm is applied to find Pareto front. After finding the Pareto front, a procedure is used to select the best solution from the Pareto front.

Human judgments are often vague and it is not easy for people to express their perceptions and expectations about quality of services using an exact numerical value. It is more realistic to use linguistic terms to describe the expectation and perception value. In this paper, combined approach of SERVQUAL and fuzzy logic to evaluate the quality of educational services provided at Islamic Azad University of Qom. This study was descriptive and cross-sectional was conducted in 2013. For implementing the study, the sample 365 of students was selected randomly by stratified sampling. Data was collected through standard SERVQUAL questionnaire. Validity of questionnaire was confirmed by experts and its reliability using Cronbach's alpha was 0.84. For analysis of data descriptive statistics and Mann-Whitney, Kruskal-Wallis and Wilcoxon tests were used. Comparison between the perceptions and expectations of the students indicated that there were significant differences in all dimensions of educational service quality (P<0.05). The average gap of educational services was 79/0, which represents a negative gap in service quality. The greatest and lowest gap were in the tangibles (-0.90) and responsibility and reliability (-0.74), respectively. The gap between the quality of education in terms of gender, college and field, there was a significant difference (P<0.05). Based on the findings of the study the largest gap was in the tangible factors. It is suggested to enhance the improvement of library resources and increase computer workshops in priority.

One of the major concerns of today’s human is the contamination of agricultural soil with different chemical pollutants، especially heavy metals which is considered as one of the important challenges of agricultural development and hence rural development. The use of a variety of organic and chemical fertilizers، municipal waste، pesticides، insecticides، herbicides and many other agricultural processes that affect locally on the soil potentially will face agricultural and rural development with problem. This research، in order to evaluate the effect of organic manure (animal and compost) on the growth rate and performance of Barbarea Verna (Lepidium sativum) plant as well as the uptake of copper، lead and chromium as heavy metals by the root and aerial organs of the plant، by split plot based on the completely randomized block design with six Treatment and four replications was conducted in the Crop Field Research Paradise of Zabol University in 2008-2009. The Treatments consists of plots contaminated with heavy metals three Treatments (manure، compost and chemical fertilizer) and non-contaminated plots three Treatments (manure، compost and chemical fertilizer). The results showed that the non-contaminated Treatments compared with contaminated Treatments enjoyed higher performance. But this difference was not statistically significant. Considering the comparison of the data average، the most performance of Barbarea Verna plant was obtained from the chemical fertilizer Treatment non-contaminated with heavy metals (6. 09 ton/ha) and the least performance of Barbarea Verna plant was also taken from the manure Treatment contaminated with heavy metal (4 ton/ha). The results of data variance analysis showed that among various types of fertilizers، from the view of heavy elements accumulation in the plant mass، there is a significant difference. The comparison of data average of both contaminated Treatment and non-contaminated Treatment indicated that the accumulation of heavy elements both in the root tissue and in the aerial organs of Barbarea Verna plant that were treated with various types of fertilizers contaminated with heavy metals was more than non-contaminated Treatments.
