In order to improve titanium corrosion behavior, we can increase the thickness of oxide layer on titanium surface during anodizing process and by electrochemistry. In this research, self-color anodizing of Ti in sulfuric acid was done, and anodizing layers were created in different colors. The highest value of chromaticity was 37.8 for the anodized sample in 10 V, and the lowest value was 8.6 at 15 V. The oxide layer thickness was calculated by optical method (light refraction). The anodic film thickness increased by increasing the anodizing voltage. The highest thickness of anodic film was 190 nm in sulfuric acid solution for the anodized sample in 80 V. Corrosion resistance of anodized Ti was studied by potentiodynamic polarization curves in biological solution of RingerÕs at 37°C. On increasing the anodizing voltage further, corrosion rate of the alloy increased from its lowest rate. The lowest rate of corrosion was for the sample anodized in 10 V, which was 0.96 3 10 23 mpy.

Abstract-New products based on modern technologies (high-tech), in order to enter the market, face a number of challenges such as high investment required for research and development of these products, high cost of labor force, high cost of products, making profit at advanced stages, low life expectancy, high level of associated risks and required innovation. In terms of marketing these products, issues such as centralized decision making by the manager or the owner, dynamic environment, existence of larger competitors with higher resources and influence in the market, high expectation of customers and lack of resources are just some of the issues to mention.In this study the effects and functionality of network marketing strategies such as reduction of costs, increase in the rate of sales, brand making, job creation, effective networking, high level of innovative potentials, and increase in liquidity as the result of growth of sales; which itself is obtained by viral marketing and its expansion to a social networking site with exchanges of social capital has been investigated. The statistical population are a number of small scale companies providing microfiber Nano silver cleaning cloths based in the city of Tehran. The research method which has been used in this research is qualitative research method.The results of the research show that by providing a favorable reward plan in network marketing, microenterprises offering high-tech products can overcome many of their problems and difficulties in presenting, selling and promoting their products in the market.Index Terms-Microenterprises, network marketing, social network, social capital, viral marketing.I.

The study aim is to identify themes of entrepreneurial strategy of new venture in international markets entry. In the study, using qualitative research methods, a sample consist of five new ventures in central state of Iran studied. Interview technique was used for data collection. The data analysis results showed that the identification of new ventures entrepreneurial strategy in international markets entry by industrial managers consists of identifying opportunities, managing uncertainty, capabilities discovery, and customer discovery and channel discovery which have been approved by various studies.

New service development is increasingly becoming one of the most important aspects of business strategy in both service and non-service industries. In todays economical world where has become more service oriented, it can be said that the new service development (NSD) is one of the most important components of growth in dynamic environments. As new proposals lead to an increase in income, profit and develop in market share. The aim of the study was to survey new service development and factors affecting its financial performance in banking industry. In terms of research philosophy this is a demonstrative, in terms of research purpose and direction it's a practical and descriptive, and in terms of research implementation strategy it's a survey research that has been executed in cross-sectional time period. The purpose of the research sampling was to examine the new services, which are provided in the various banks. Stratified probability sampling method used is based on 150 questionnaires in headquarters and branches of different banks, which are located in Tehran city, and 118 questionnaires were gathered. Data obtained from the questionnaires were analyzed in both descriptive and inferential level by using SPSS version 21 and Lisrel 8.8 Windows version. Structural equation modeling techniques (confirmatory factor analysis and structural analysis) have been used to test the research hypotheses. Results of the research showed that cross-functional teams and learning orientation have positive impact on the new service marketability. And indirectly have a positive impact on the financial performance of new service. Customer involvement and learning orientation have positive impact on the new service launch preparation, but the effect of new service launch preparation on new service financial performance has not been proved in the current study.
