Urban space is combination of two parts including form and meaning. The signs in the urban space together with its codes form the part of urban space meaning. Signs are the part of the visual media which are presented for the citizens, So the citizens discover code's meaning by decoding of internal concept and are influenced by it. The question is that the signs which are presented to citizens as a visual media what relations they have with national identity elements? Urban signs can have meanings of national identity elements into their codes. It is notable that prominence of some elements and factors rather than others has role in formation, reinforcement and representation of national identity. Therefore in this research an attempt has been made to evaluation of relations between the signs meaning in urban space and elements of national identity factors in the 6th, mural district of Tehran as a case study by using of qualitative analysis and the basics semiotics. The results of this research in the 6th district of Tehran indicated that urban signs are influenced by national identity factors and they have meanings and concepts of it inside themselves. Also prominences of some national identity features rather than other features lead to formation of national identity and also play the important role in reinforcement and representation of national identity by repeating the meanings influenced by national identity.

Iranian-Islamic architecture is a precious heritage of Shia culture which is the legacy of past generation, the valuable samples of which are well observed and recognizable in planning, design, and management system of historical cities of Iran. The relation between Iranian-Islamic architecture and theoretical basis, principles of Islamic jurisprudence, and verses of scripture and revelation shall be a valuable treasure in guiding and developing Iranian contemporary architecture and urban development. An overview of practical experiences and their theoretical foundation in the areas of architecture, urban development and urban management indicates that explaining the relation between theoretical principles and physical specifications is the prerequisite for realization and implementation of an architecture style and orientation; it is on the basis of such approach that the subject of the present research could be analyzed in the bed of Koran verses and their valid interpretations. The main research question is that what does identity mean in Islamic architecture? And where is the position of this definition in the formation of Islamic architecture? What are the requirements for realization of the rule of no injury loss in Islam in the bed of forming Islamic architecture? How Islamic architecture is formed in the bed of identifying elements and where is the position of these elements in Islamic architecture? The research method used in this study is based on a logical reasoning method. Upon drawing the theoretical framework of the research, the specialized and scientific resources are analyzed using comparative method, then the resulted opportunities and challenges are discussed. This research is required to be treated qualitatively, so it will be viewed based on free research paradigm using library sources and field study.

Background: Aspergillosis is an opportunistic infection caused by Aspergillus spp in immunocompromised patients. The role of HSP90 in Aspergillus drug resistance is still unknown. The aim of this study was to evaluate the correlation between the presence of HSP90 gene and polyene resistance in Aspergillus spp using PCR.
Materials and Methods: In this study, 32 Aspergillus strains were used, which were isolated from patients susceptible to aspergillosis through Bronchoalveolar lavage (BAL) and identified by conventional methods. The isolates were cultured on Sabouraud dextrose agar (SDA). Susceptibility testing against amphotericin B was conducted according CLSI standards (M38-A). Also, the presence of HSP90 gene was evaluated using PCR.
Results: Of 32 Aspergillus strains used in this study, 16 (50%) isolates were identified as A. Flavus, 12 (37.5%) isolates as A. fumigatus, and 4 (12.5%) isolates as A. terreus. Among these species, 19 (59.37%) isolates were sensitive to amphotericin B whereas 13 (40.62%) were resistant. Moreover, there was a significant difference  between the presence of HSP90 gene and resistance to amphotericin B in Aspergillus species.

Conclusions: The presence of HSP90 gene provides evidence that shows this gene may play important role in resistance to amphotericin B in Aspergillus isolates. Although numerous regulatory genes are involved in resistance mechanisms, they remaines to be more clarified

The effects of mucal proteins of sea anemone, Stichodactylahaddoni,on different stages of embryonic development of zebra fish (D. rerio) were examined. The sea anemone samples were collected from the intertidal areas of the Hormuz Island (Persian Gulf), and were frozen at -160 °C. Protein and peptide components were extracted by 100% methanol. Following the total protein assessment by ELISA, three concentrations (2.1, 3.7 and 7.4 mg/ml distil water) were prepared. From each concentration, 2 ml was added to the microplates containing 150 zebra fish eggs each, with 2 replications; microplates with normal aquarium water was also used as control group. The eggs were incubated for 72 hrs and the process of embryonic development was observed every 6 to 12 hours. Results showed that the embryonic development was normal in the control group, while the eggs treated with 3.7 and 7.4 mg/ml ofmucal proteins degenerated and blackened in less than 12 hours. Also a delay in the phase of growth in embryonic development was observed in the group with 1.2 mg/ml of protein. Our results showed that the mucal proteins from this sea anemone can affect embryonic development rapidly, causing delayed growth at low concentration, and cell lysis and embryonic degeneration at high concentrations.

In this study, anti Alternaria solani effects of essential oils of 11 medicinal and aromatic plant species belonging to four families collected from the west of Iran were investigated based on agar dilution method with five replications at concentration of 1.0 µl/ml. The results showed that the highest inhibitory effect belonged to Oliveria decumbens, Cinnamomum zeylanicum, Carum copticum and Thymus kotschyanus which completely inhibited the mycelial growth of the fungus. Therefore, their activity was examined in lower concentrations, too. The essential oil of O. decumbens at concentration of 0.50 and 0.25 µl/ml completely suppressed the mycelial growth of the fungus. The major constituents of its essential oil were carvacrol (46.53%), thymol (23.75%), p-Cymene (13.70%), γ-terpinene (7.66%) and myristicin (3.65%), respectively. Thus, the essential oil of this species with the highest anti-Alternaria activity could be selected for further studies on in vivo application as natural fungicide.

This paper presents a framework for long term transmission expansion planning in competitive, electricity markets. Transmission lines and phase shifters are taken into account as expansion options. Maximization of the network users' benefits, with satisfying security constraints are considered as the criterion for transmission expansion planning. The elements of the objective function are the benefits of each network. The proposed model is as a non-linear mixed-integer programming (NLMIP) optimization problem. A GA (Genetic Algorithm) based method and quadratic programming (QP) approach is used to solve the problem. The discrete decision-making variables of the expansion plan are optimized by genetic algorithm, while QP optimizes the continuous variables.

Arbitrage is a known economic term, implying simultaneous transaction on commodities. For instance, a Generation Company (GenCo) may involve itself in selling fuel, emission allowance and etc., instead of generating either active or reactive power. Moreover, arbitrage between active and reactive powers can, in turn, be considered. In this paper, arbitrage between active and reactive power is considered from Independent System Operator (ISO) viewpoint. A pool model is employed. ISO runs an optimization problem, by which, it could determine and predict GenCos behaviours; in terms of participating in active and reactive power markets for the next twelve months. A normal distribution function is used for price forecasting. Two 3-bus and 14-bus test systems are used to demonstrate the capabilities of the proposed algorithm.

Network expansion studies normally offer new power lines, new substations or expansion of existing substations. They are generally proposed based on technical requirements, but financial restrictions are not considered. Because of financial restrictions, ranking of network expansion plans is required. In this paper an algorithm for such ranking, based on technical and financial view points and proposes suitable parameters. This algorithm may be used to compliment static or dynamic expansion planning studies of electric power networks.

The new competitive environment changes the paradigm of power system operation. In the transmission area, open access process provides fair accessibility for all market participants. Congestion management is one of the most important side effects of this new process. This paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the network critical buses. The critical buses including both generation and interruptible loads, are determined through a sensitivity analysis. Due to the important effects of the market pricing rules on the congestion cost and its allocation, two types of these rules, namely uniform and pay as bid pricing are investigated in the paper. The numerical results of case studies show the effectiveness of the proposed approach.

According to the latest report of the International Monetary Fund, the share of the US dollar in the total foreign exchange reserves of the world's central banks is about 63%, while the share of the Euro is 20% and the share of the Yuan is 2.5%. This study argues for the hegemonic position of the dollar in the world economic system and then tries to understand the future scenarios of this position. The ultimate goal of this study was to analyze the solutions of Iran's international banking system to deal with the position of the dollar in the global financial system. In this regard, a qualitative research has been conducted by qualitative content analysis method with the presence of 15 experts in the field of international banking. The data collected through semi-structured interviews have been analyzed and the results indicate that: Continuation of dollar hegemony, replacement with another national currency, strengthening of multilateral currencies and replacement with digital currencies are the four future scenarios of the global financial system. Subsequently, the solutions of Iran's international banking system to deal with it are: development of strategic financial relations with China, conclusion of multilateral monetary agreements, exploitation of digital currencies, and use of non-bank trade mechanisms.
