        One of the most important branches of pharmaceutical science is drug delivery, which has attracted the attention of researchers in recent years. The matter that leads researchers to study about drug delivery is to increase the effectiveness of the drug and reduce the toxicity of the drug by drug carriers. In this paper, every kind of drug delivery carriers are investigated which demonstrate the importance of drug delivery and drug release. Manuscript profile

        Lack of an efficient video frame delivery method due to high delay in Pull method and large number of duplicated frames in Push method, as the two main content delivery methods among peers, has been a strong motivator for introducing hybrid methods based on these two basic approaches for live video streaming in mesh-based peer-to-peer networks. Recent studies show that these hybrid methods suffer from inherent challenges of the two basic approaches because they are just a sequential or parallel execution of them. In this regard, this research introduces AMIN, a novel hybrid method for intelligently exchanging video frames among peers. Using AMIN, contrary to Pull, each peer sends its buffer map status (BMS) to its two-hop neighbors and the peer who receives the BMS will immediately check which video frames it can send to that peer instead of requesting missed video frames in its buffer from it. In addition, contrary to Push and because of BMS, peers do not blindly send video frames to their neighbors. Simulation results show that video quality considerably increases in peers, while End-to-End delay, received delay and the number of duplicated frames decrease in comparison with two basic methods as well as another recent similar approach.

        3 - Legal And Jurisprudential Study Of The Commonalities And Differences Between The Legal Action Of Taking Possession And Delivery Of Object And The Temporal Symmetry Of These Two Legal Acts In The Contract Of Sale

        Reciprocal contracts are among the important and also widely used contracts in the legal and judicial systems as well as the social arena of countries that have been regulated since ancient times, especially in the field of law, especially in the field of private law and personal relations, contract law and Islamic jurisprudence which regulated and attentioned by legislators and Sharia has been holy. according to the Iranian legislator, the essential elements for the validity of a contract in reciprocal contracts have always been considered by the parties to the contract (contractors) so that the contract is considered valid and effective in conditions of legal and jurisprudential status. one of these essential elements the validity of contract and in particular the contract of sale, the existence of the object of the contract and necessity for seller ability to delivery of object to the other party to the contract and their taking possession in order to fulfill contractual obligations. In this article, the author has tried to briefly state the conditions and characteristics of legal actions of taking possession and delivery, and then discuss the differences and analytical discussions of the incident between lawyer and jurisconsult and in addition, to stating the differences between taking possession and delivery and to the contract of sale, wants to reach to a result and point of view on this matter.

        4 - A Review of Hydrogels Containing Fibers in Drug Delivery Systems
        Mohammad Hossein Karami Majid Abdouss Mohammadreza Kalaee Omid Moradi

        Hydrogels are three-dimensional networks of hydrophilic polymers capable of absorbing and retaining significant amounts of fluids, which are also widely applied in wound healing, cartilage tissue engineering, bone tissue engineering, release of proteins, growth factors, and antibiotics. In the past decades, a lot of research has been done to accelerate wound healing. Hydrogel-based scaffolds have been a recurring solution in both cases, although their mechanical stability remains a challenge, some of which have already reached the market. To overcome this limitation, the reinforcement of hydrogels with fibers has been investigated. The structural similarity of hydrogel fiber composites to natural tissues has been a driving force for the optimization and exploration of these systems in biomedicine. Indeed, the combination of hydrogel formation techniques and fiber spinning methods has been very important in the development of scaffold systems with improved mechanical strength and medicinal properties. Hydrogel has the ability to absorb secretions and maintain moisture balance in the wound. In turn, the fibers follow the structure of the extracellular matrix (ECM). The combination of these two structures (fiber and hydrogel ) in a scaffold is expected to facilitate healing by creating a suitable environment by identifying and connecting cells with the moist and breathing space required for healthy tissue formation. Modifying the surface of fibers by physical and chemical methods improves the performance of hydrogel composites containing Manuscript profile
