Soil samples taken from the study area after a period of 5 months under greenhouse cultivation, 3 rootless soil samples and 12 soil samples with different root densities were tested for direct cutting to measure the shear strength of soil composition and roots And the parameters of internal friction angle and adhesion of root-reinforced soil were obtained and compared with rootless soil samples.Results: In general, the density and number of roots has been reduced with increasing depth, and also the root density index decreases with the depth increases.Using these results and direct cutting tests was calculated the amount of armament.The presence of roots has created a significant resistance to soil shear strength, which has been affected by increasing the amount of soil adhesion.In contrast, the internal friction angle of reinforced soil decreases with respect to the rootless soil and has the opposite behavior of the adhesion factor.And its changes are much less than the changes of the adhesion factor.Therefore, it can be known that increasing the shear strength of soil reinforced with alfalfa root is equivalent to increasing adhesion.Conclusions: The results of this study show that there is a direct relationship between root density index and soil shear strength. The highest and lowest reinforcement rates for 28 and 5% density index were 87.5% and 7.5% increase in soil adhesion, respectively and there has been a maximum reduction in internal friction angle relative to rootless soil of 5.5%. This study showed that there is a decrease in the relationship between depth and root density index, depth and strength of reinforcement as biotechnological characteristics of alfalfa species.

The increasing trend in the consumption of food flavoring compounds has motivated the production of food flavors therefore the global demand for natural flavors and aromas is continuously increasing. Plants and microorganisms are the main sources of flavor and aroma compounds such as terpenoids, aldehydes, methyl ketones, but due to their production in lower concentrations, the isolation and extraction of such value-added chemicals is expensive. Therefore, the biotechnological production of flavor compounds has been considered.Materials and Methods: In the last decade, research has been carried out in the field of biological production of flavoring compounds. In this study, main biotechnological methods including the use of enzymes, microorganisms, tissue plants and cell culture have been investigated.Results: Conventional techniques for producing flavor compounds are not sufficient in terms of quantity and variety due to the rising market demand. Current flavor production methods use chemical synthesis, which can produce a greater number of flavors in less time. However, the demand for natural products has created the need for new methods to produce flavoring compounds labeled as natural origin. Biotechnological production is an attractive alternative to flavor production because it occurs under mild conditions, has high selectivity, produces no toxic waste, and produces products that can be labeled as "natural." Natural flavoring compounds obtained by biotechnological processes play an increasing role in the food, cosmetic, chemical and pharmaceutical industries due to the increasing consumer demand for natural food additives.Conclusion: Emerging techniques in biotechnology have enabled industries to produce compounds that might be considered natural. There is no doubt that these technologies will become more important factors in the production of flavoring chemicals in the future due to their many advantages. Manuscript profile -

In this research, the policy making tool of Pabarja programming has been used as post-programming methods. The fields of information technology, aerospace technology, and biological technology have been the studied examples. Developmental policy documents in these three areas have been analyzed. Based on the results, the policies were divided into four categories: very strong, strong, partially strong, and non-strong. Instrumental policies in the country's technological development documents were compared in three studied fields. Based on the results of the information technology document, it is more durable than the other two documents, and the bio-technology document has the lowest degree of durability. In the bio-technological document, not only the level of persistence is low, but they also do not have correlation with each other, and the things that were important in the document have less persistence. The comparison between dependence on technological fields and dependence on scenarios shows that policies are more dependent on scenarios than on technological fields. Manuscript profile -

In each of infertility treatments, the unified dimensions of this experience are flawed. This study examines the help of fertility biotechnologies in maternal issue. Thus treatments in which the third person enters to the treatment process, have more complex social dimensions than treatments without the need for the third person. In this study, "fertility biotechnologies as the pain experience" was examined, and "donation intermediary" and "reasons and motivations of donation and its social consequences" were extended and analyzed. The study concludes that in the treatment of infertility whether with feminine or masculine origins, not only the main burden of physical side effects is for women, but also, the social burden of biotechnologies in treatment is affected women. So, what is considered as the motherhood phenomenon is also viewed in infertility treatments. However, due to the men's greater control over the economic resources of the family, in many cases, the final decision on starting or continuing the treatment process through fertility biotechnologies, is made by men.

Although there is not enough experimental evidence about the possible benefits and harms of interfering with the genes of foods and animals using gene technology, necessary precautions should be taken to minimize the possible effects and risks on the environment and future generations. The haram or halal status of GMOs, which has started to take place in the food sector, has also been seriously discussed in terms of Islamic law. Issues for which there is no clear provision are tried to be decided within the framework of benefit-harm balance and the framework of the general principles of fiqh. To determine the verdict of Genetically Modified Foods, its effects on health, environment, the economy, and politics should also be taken into account. Manuscript profile -

Therefore, in the present study, the recent advances in biotechnology in the field of preparing wound dressings from compounds obtained from plants and animals for people with diabetic foot ulcers have been discussed. In this research, the methods and approaches of delivery of therapeutic agents for the treatment of DFUs and in fact the recent results of in vitro and in vivo studies, emphasizing the unique potential of wound dressings based on natural polymers in the treatment of DFUs, have been collected and analyzed. This expansion is expected to be driven by advances in technology, increased incidence of chronic wounds, and an increasing elderly population. A review of the challenges ahead in the treatment of chronic wounds reveals the inadequacy of the effectiveness of some wound care products, suggesting that families and governments must contend with medical challenges for longer periods. Diabetic foot ulcer (DFIU) is a chronic ulcer that can cause severe infections and even amputation. Biomaterials that are currently used as matrices for wound healing can be classified into natural and synthetic types according to their origin. Natural biomaterials such as chitosan, alginate, cellulose, hyaluronic acid, silk fibroin, and collagen have been widely recommended for diabetic foot wound healing due to their easy degradability, remarkable biocompatibility, reduced inflammatory responses, and non-immunogenic nature. Biotechnology guarantees the possibility of using natural biomaterials to develop advanced wound dressings with appropriate and patient-friendly therapeutic results. Manuscript profile
