Abstract
In the present study, the effect of ground sesame seeds in three levels of 0, 0.15 and 0.25% on features of biological, chemical and sensory evaluation silver carp surimi gel in vacuum packing for 4 months in freezing temperatures (-18°C) was investigated. The results showed that the highest levels of volatile nitrogen month 4 in the control (21.99±0.32mg per 100g), respectively. The thiobarbituric acid did not like the higher limit the amount of free fatty acids is increased. The highest bacteria in month 4 in the control (6.86±0.05Log cfu/g) treatment, respectively. The highest and lowest amount of lactic acid bacteria, respectively, on May 4 in group 1 (4.86±0.10Log cfu/g) and May 1 in all treatments (2.00±0.00Log cfu/g), respectively. Sensory evaluation factors during 4 months in freezing temperatures are not significantly different the colorimetric parameters (L*, a*, and b*) and tissue treatments poll 0.25% sesame seed powder was the best treatment. According to the results of chemical analysis, sensory and microbiological shelf life achieved the best treatment was 0.25% in the fourth month, ground sesame seeds.

Abstract
To move from one stage to another in all societies, there would have always been many social norms. One of the most important norms along the history has been reproduction, which, depending on the region, has certain beliefs and different strategies of achievement. Thus, the present study seeks to address the issue of fertility and its attitudes, methods effective in Iranian culture for the diagnosis of pregnancy and sex determination of children, as well as for the prevention of pregnancy and abortion. On this basis, the present study was conducted with a descriptive-analytical approach with the analysis of literary, religious and historical texts reflected in Iranian popular culture. Fertility and the entry of the new member of the Iranian family were considered as a kind of honor. Therefore, there are scientific and sometimes unscientific methods of identifying the fertility or sterility of women that have been effective for women's fertility and for the prevention of abortion and infertility. Given the importance of gender and neonatal physiology, in order to determine sex and even the health and beauty of children, the predicted urine test and the apparent signs of the body have been predicted and attempted to provide changes in this regard by feeding medicinal plants as well as fruits and vegetables.

Abstract
Microorganisms play an important role in formation of mines. In this research, the bacteria inhabiting in Aq-Darreh Takab gold mine were isolated and compared with agricultural soils. The isolates were characterized using 16S rDNA sequencing and the homology searches were performed using BlastN, EzTaxon, and RDP Classifier web tools. Resistance of the isolates was also investigated against arsenic and silver in the presence and absence of 3.5 ppm gold. Although the control soil showed a wide variety of bacterial diversity (43 isolates belonging to 13 genera), only 17 isolates belonging to 11 genera were isolated from mine soils including Acinetobacter, Agrobacterium, Comamonas, Deinococcus, Listeria, Microbacterium, Micrococcus, Pseudomonas, Rhizobium, Roseomonas and Staphylococcus. Among the isolates, A. radiobacter, D. ficus, M. antarcticus, M. luteus, R. radiobacter and R. selenitidurans were able to tolerate different amounts of arsenic and silver in the presence of gold, among which A. radiobacter and D. ficus showed the highest resistance in such a way that they grew in the presence of 50 ppm arsenic, 50 ppm silver, and 3.5 ppm gold. Our results showed that bacterial diversity in soils containing gold, silver and arsenic metals is less than agricultural soils. It was also found that the bacterial diversity in gold mines depends on the amount of gold and the amount and type of associated elements. Due to high resistance of two endogenous bacterial species to arsenic and silver, A. radiobacter and D. ficus, have also the potential for industrial purposes in environments contaminated with these metals.

Abstract
One of the most important challenges related to fresh meat products (especially sheep liver) is the short shelf-life of the product. For this purpose, synthetic preservative compounds are used to extend their shelf life, which have many side effects on human health. In this research, the effect of using an edible coating containing phenolic compounds of pomegranate peel cross-linked in the structure of aloe vera hydrogel was studied to extend the shelf life of sheep liver. Physicochemical (pH, peroxide index, total volatile nitrogen, thiobarbituric acid index and color parameters L*a*b*) and sensory (aroma, color, texture and overall acceptability) properties of the product in storage days of 1, 3 and 7 days and in the storage temperature of +4oC was evaluated. The results indicated that, the lowest value of monohydroperoxide formation (i.e. peroxide index) was observed in test samples coated with aleo vera gel containing phenolic compound of pomegranate peel extract that corresponding to the lowest total volatile nitrogen. Generally, in accordance to the results of sensory evaluation and quality tests, using of aleo vera gel containing bioactive compounds of pomegranate peel extract is recommended for shelf life extending of sheep liver.
