Research Subject: One of the important methods in the treatment of skin wounds is the use of wound dressings. Recently, the use of polymer-based wound dressings has become increasingly common. The use of natural polymers is very important in wound dressings. The aim of the present study is to design and manufacture a polyvinyl alcohol/aloe vera wound dressing with the capability of healing skin wounds.
Research Approach: The electrospinning method was applied to prepare the samples. Aloe vera gel was first extracted, purified, and powdered by freeze-drying. In all samples, the amount of polyvinyl alcohol and aloe vera powder was fixed at 8 wt.%. This value was selected empirically based on the quality of the produced fibers. Different samples including different amounts of polyvinyl alcohol and aloe vera were produced and their properties including morphology, tensile strength, swelling, degradability, and antimicrobial properties were investigated.
Main Results: The results showed that the dropless random oriented fibers with uniform diameter were produced. The diameter increased with increasing aloe vera contribution, which was attributed to an increase in viscosity due to the presence of aloe vera. With increasing aloe vera contribution in the samples, tensile strength decreased and the elongation percentage increased. The swelling behavior of the specimens was evaluated by measuring the weight of the specimens in a simulated skin environment and the results showed that the presence of aloe vera increased the hydrophilic properties of the specimens. Antimicrobial activity of the samples against two gram-positive Staphylococcus aureus and Gram-negative Pseudomonas aeruginosa was investigated using the disk diffusion method and it was found that the presence of Aloe vera in the samples brought antimicrobial activity against Pseudomonas aeruginosa. Finally, the findings of this study confirm the feasibility of using polyvinyl alcohol /aloe vera for the production of the electrospun wound dressing.

Various thermo mechanical processes have been studied to improve the mechanical properties of 18Ni-Co-Mo steels. In this work, the effect of interpass aneal time on the mechanical properties of the 18Ni-Co-Mo steel was investigated, using the rolling experiments. Hot rolling process was performed in two passes. The reduction of area was 30% in the first pass at 1100 °C. After first pass specimens were air cooled to second pass temperature (900°C) and held for various interpass time (2 sec, 5 min and 10 min). The second pass was performed at 900°C for 20% reduction of area. After that, the specimens were directly water quenched to retain the microstructure present at the second pass. Tensile and charpy tests samples were machined from hot rolled specimens. The results showed that grain size was decreased significantly at these conditions by increasing the interpass time from 2 sec to 5 min. This was attributed to the static recrystallization. With an increase in interpass time to 5 min, tensile strength was increased, without significant change in charpy impact energy. Increasing the interpass time from 5 to 10 min, increased austenite grain size. This was attributed to the grain growth. The results indicated that the interpass time of 5 min can be considered to obtain the maximum tensile strength.

Seyyed Mehdi Enjavi Nezhad Assistant Professor, Faculty of Law, Shiraz University   Mohammad Emami Assistant Professor, Faculty of Law, Shiraz University    Pious endowment, as a behavior that makes possible the continuity of charity has been common among various nations from long ago; however, in Islam because of the emphasis of the Holy Quran and the Muslims' care on charity affairs, it has got a more significant place, in the manner that it is discussed and scrutinized by the jurists and it's various dimensions have been taken under the juristically rules and principles. Compiling the Civil Law and allocating the articles No. 55 to 91 to it, endowment is formed as a legal foundation subject, and through the establishment of "Endowment Organization", it would be controlled by the government and Law. Expansion of the government activities in affairs such as adopting policies toward restricting the private ownership due to the fulfillment of various purposes has led to the compiling of laws that contain endowment cases, the most important of which is supervising the sale of ensoment properties and changing them to the better. In this article, the process of changes in law has been surveyed and the principles of endowment sale and changing to the better bas been clearly explained. In addition, considering the interests of endowment, the way for optimum use of endowment in the framework of full filling the real purpose of those who do it, would be prepared and the way for compiling suitable laws in this case would be paved.

This paper seeks to respond to this major question that if Iran accedes to the World Trade Organization (WTO) and observes copyrights, in the realm of intellectual property, what demand and supply changes would occur in Iran’s book market. To respond the above question first some instances of breaching the copyrights in book publishing sector is investigated. Then calculating the price and income elasticity, the impact of observing the copyrights on price and income, and therefore on the demand and supply for books in short term is demonstrated. The findings of this research reveal that with accession of Iran to WTO and observation of copyright, some of the subsidies to the book sector must be terminated, and also the non-national authors would receive royalties. With elimination of subsidies and payment of royalties book price will increase by an average of 7.5 percent and demand would decrease by 13.35 percent. But, supply will show less sensitivity and its increase in short term would be insignificant. Yet, as experienced in other countries, for numerous reasons such as entering the international markets and increased quality, the printing volume of books will increase. In long term, the experiences of other countries have shown the same trend.

   This study was carried out on the social history of the village in Iran and to identify and categorize the social issues in the villages of Salas area in 1325 AH. Despite the importance of rural society in Iranian history and the eve of the Constitutional Revolution, few studies have focused on issues of the peasant movement and territorial issues, relying on observers, activists, and little reflection on rural issues in the media at the time. While understanding the rural community requires a deep and broad understanding of social relationships based on a comprehensive description of the reality of the community in question at any given time. The present study was based on data from the Legal Documentation Collection (Sentence Implementation Office, 1325 AH) of a sample province (Mahallah Salas and ,Shaghaghi), comprising a homogeneous community of middle villages, Garmrood and Sarab, Miyaneh, what were the challenges and social issues of these rural communities?

The present research attempted to explore the grounds for granting compulsory licenses of intellectual property rights and the possibility of granting this kind of license in Iranian legal system. Granting of compulsory licenses is possible both in the fields of copyright and industrial property rights. According to the related international instruments such as Paris Convention for the Protection of Industrial Property, Bern Convention for the Protection of Literary and Artistic Works, TRIPs Agreement and Rome Convention as well as the national laws of many countries, compulsory licenses are granted generally in two grounds: when the right holder abuses his rights and when protection of public interests such as public health, national defense and correction of anti-competitive practices are necessary. Apart from the draft of Iranian patent law and the draft of "Competition Enhancement and Monopoly Regulation", both of which are under review by the Islamic Parliament (Majlis), there are no specific provisions regarding the licenses. However, granting of compulsory licensing may be legally acceptable with respect to Iran’s membership in Paris Convention for the Protection of Industrial Property. The general rule of "prohibition of abuse of right" under the 40th principle of the Iranian Constitution Law may also be another legal basis for compulsory licensing in the case of the abuse of monopoly rights by the IP right holders.

This paper aims to study the relationship between intellectual property and patent protection and economic growth in Iran using Auto Regressive Distributed Lag (ARDL) technique during 1979 – 2010. This model is based on economic growth models in 1990s. The number of patents is used to measure the impact of patents on economic growth. Moreover, we investigate the casual relationships among economic growth, degree of economic openness, foreign direct investment, information and communication technology (ICT) and human development. The results indicate that patent protection has a positive and significant impact on economic growth. Furthermore, the casual relationships from degree of economic openness, foreign direct investment, ICT and human development to economic growth are positively significant. Based on numerical results, one-unit increases in ICT, HDI, patents, government expenditure and oil revenues lead to 0.10, 0.12, 0.10, 0.39 and 0.21 percent increase in economic growth respectively. Hence, we conclude that the higher intellectual property and patent protection results in high economic growth.

Nowadays, the peptides and proteins possessing anti-cancer, anti-allergic and anti-inflammatory properties are used for disease treatment. Brazzein is a sweet protein containing 54 amino acids and according to reports, it has anti-cancer properties based on sequence and structurehas sequence. In this study, the role of position 40 aspartate in the structure and function of wild brazzein protein and mutants as well as the anti-cancer properties of the peptides obtained on the TLR5 receptor were investigated. For this, several models of mutated forms were designed and constructed using Modeller.v.9.20 software. Then, the accuracy of the models and the physico-chemical properties of wild type (WT) and mutants of D40N, D40R and D40Deletion were evaluated using various bioinformatics servers and softwares including ProtParam, ProtScale, SAVES, PIC, ModEval, and PredyFlexy. For predicting anticancer properties, the sequence of WT protein and mutants was examined and compared using ACPred and iACP servers. The quality and analysis of WT protein and mutants binding as a ligand with TLR5 receptor, triggering an anti-cancer signaling pathway, were investigated through molecular docking using HADDOCK software.The results of bioinformatics parameters analysis indicated the possibility of improving the stability of brazzein structure and function, and the probability of increasing the available surface to bind to the receptor. Moreover, based on the results of molecular docking analyses, the ability binding TLR5 receptor was higher in D40R than the other proteins indicating an increased probability in anti-cancer properties of the mutant.

Integrated circuits are the core components of any digital equipment, in the information technology era. Due to heavy money and time investment needed to establish the integrated circuit industry, the ease of copying the layout-designs on a fraction of original expenses, and the disability of existing copyright and industrial property regimes to protect the right holders, the industrial countries adopted a sui generis form of intellectual property right. This article is directed to discuss the conditions that layout-designs of integrated circuits should fulfill to be entitled for the intellectual property protection. Furthermore, the creator duties, which are required by Washington Treaty 1989 and TRIPs Agreement 1994, and some selected national jurisdictions to be eligible to exercise his rights will be studied in details.

: This paper investigated experimentally the effect of nanoclay on ballistic impact behavior of GLARE. The prepared GlARE is made of two Aluminum 2024 facing sheets and E glass/ epoxy/nanoclay as nano composite core. Nano composite section has been composed of undirectional E glass 409 g/m2, resin CY 219, hardner HY 5161 and nanoclay closite 30B dispersed into the epoxy system in a 0%, 4%, 7% and 10% ratio in weight with respect to the matrix. All panels fabricated using laid-up method in fiber volume fraction of 60%. Ballistic tests were conducted using Gas gun at the velocity of 205 and 225 m/s. The results of the ballistic impact experiments show that the amount of Specific energy absorption variations in 4% of nanoclay content is insignificant. However, in nanoclay contents of 7% and 10%, the Specific energy absorption increases. To analyze the results of the ballistic impact on the GLARE, the effect of nanoclay on the longitudinal and transversal mechanical properties of the composite was investigated. A noticeable correlation was found between ballistic impact results and Changes of toughness in longitudinal and transversal direction.
