Tissue engineering is an interdisciplinary field that merges together, the principles of life sciences, material sciences, engineering and surgery to develop biological substitutes that restore, maintain or improve the function of biological tissues and organs. One of the most sought after aspect of this tissue engineering, pertaining to material science, is the design of polymer scaffolds. The traditional polymer scaffolds are primarily made out of PE and PP. These scaffolds are permanent and should they be removed, the patient must undergo a second surgery. Also, these scaffoldings often drop from their original position, causing injury to nearby tissues and organs. Thus the focus, today, is slowly shifting towards the bioresorbable scaffolds which get absorbed by the body. Polyhydroxyalkanoates (PHA), obtained from bacterial sources, belongs to one such class of polymers with an immense potential as scaffolds. In this paper 10-poly (3-hydroxybutyrate-co-3-hydroxyvalerate) was assessed for its application as a scaffold. 10-PHBV scaffolds, prepared by Emulsion Freezing Technique, were subjected to Tensile, In-vitro degradation, Weight loss and SEM tests under ASTM standards. Mechanical Properties, Retention and Weight Loss characteristics were then observed. The results indicate that this copolymer is to play a prospective role in the construction of bioresorbable polymer scaffolds.Keywords

Banking Sector in India is one of the growing sectors with great dynamics. There are various factors which affect the share prices of Banking Companies. It is very difficult quantify the impact of various factors on these companies. Technical analysis is the study of the market action, primarily through the use of charts, for the purpose of forecasting future price trends. It assumes that the market is efficient and the price has already taken into consideration along with the factors related to the company and the industry.
The study made to know the trends and trend reversal pattern and identify the buying and selling points based on banking sector market price movements. The study is based on secondary data from 2008 to 2010. The statistical tools like Simple moving average, Moving Average Convergence and Divergence, Relative strength Index and Rate of change method are used.
It is found that share prices of the entire banks shown decreasing trend in the year 2008 and later there is an Increasing trend in the share prices. The Moving average convergence and divergence clearly indicated the buy and sell signals at various levels. When Relative strength index values are decreasing or increasing to peak level it generates buy and sell signals. The resulted ROC value indicates Oversold and Overbought regions it generates Buy and Sell signals. It concluded that technical analysis is an effective tool for the investors to invest in short term.
