Strengthening economic potency by women entrepreneurs: A case study of Belagavi
In the global economy of the 21st century, international trade will be a key source of economic growth and development. Recent surveys conducted in several countries by the National Foundation of Women Business Owners (NFWBO) indicate that women-owned firms involved in the global marketplace have greater revenues, are more optimistic about their business prospects and are more focused on business expansion than women-owned firms that are domestically oriented. Obviously, expanding into international trade can pay off for women-owned firms. However, it is not clear that smaller enterprises are benefiting from these potential as much as larger firms. In connection with the above here an attempt has made to study the role of women entrepreneurs in economic development.

Corrosion inhibition effect of arial parts of euphorbia caducifolia for aluminium in Hcl
Corrosion is one of the most damaging and costly naturally occurring events seen today. The most common kinds of corrosion result from electrochemical reactions. It can be prevented if the metal is coated with something which does not allow moisture and oxygen to react with it. It can be controlled by either alloying or by anti rust solutions. The naturally occurring plant products are eco-friendly, compatible, nonpolluting, less toxic, easily available, biodegradable and economic to be used as corrosion inhibitor.Euphorbia caducifolia has been selected to study its corrosion inhibition efficiency. It is easily available in any season. It is native to Thar Desert of India and located on rocky terrain, hills. It is used for treatment of bleeding wound, cutaneous eruption, urinary problems, kidney stones, rheumatic pain, bronchitis, jaundice, diabities, stomach pain, hernia etc. It is also called “Thor” and “Danda-thor”. It contains caudicifolin) norcycloartane type triterpene, cyclocaducinol, triterpenes euphol, tirucallol and cycloartenol. Corrosion inhibition efficiency of arial parts of Euphorbia caducifolia was studied for aluminium in HCl. Maximum inhibition efficiency was found 99.47% in 1N HCl acid with 0.8% leaf corrosion inhibitor whereas it was 94.21% for stem and 90.51% for flower with same concentration of inhibitor i.e. 0.8%. Inhibition efficiency was studied in different concentration of acid (1N, 1.5N, 2N and 2.5N) with different concentration of inhibitor (0.2%, 0.4%, 0.6% and 0.8%). Weight loss and thermometric methods were used. Inhibition efficiency was found to be increase with increase in concentration of inhibitor and decrease with increase in acid strength.

Design and Construction of an Aluminium Mould for the Production of a Motorcycle Brake Lever
This work focused at designing and fabricating of an aluminium mould for the production of motorcycle brake lever. The pattern making, sand mould and the casting are the major step used to achieve the work. The thermal stress exerted on the mould stood at 0.67GPa which did not exceed the permissible thermal stress for aluminium. In the design of the motorcycle brake lever, it was discovered that a force of 0.58N is required to operate the lever at an effective length of 9cm from the motorcycle head. It shows that the production of motorcycle brake lever can be done locally since aluminium is largely available in the country and hence recommends that more effort should be put in by the Nigerian government for sustainability and development in this area.

Identification of Furfural in the Coconut Shell Extract and its study as Green Corrosion Inhibitor in acid media
The extraction from the agricultural waste like coconut shell using sulfuric acid and the identification of furfural in the extract treated as corrosion inhibitor. Extracted furfural was characterized by Fourier Transform Infra-Red (FTIR) spectroscopy and High Performance Liquid Chromatography (HPLC). The inhibition efficiency of extracted furfural was studied on the corrosion of mild steel in 0.5M H2SO4 with different concentrations by weight loss method and Tafel plot techniques. The inhibition efficiency increases with also increase in the extract concentration. The effect of temperature on corrosion behavior was also studied over the temperature range of 30–45°C. The results indicate that the inhibition efficiency increases with increase in concentration of inhibitor and decreases with rise in temperature. Electrochemical polarization (Tafel plot) data explores the mixed mode of inhibition. The extracted Furfural follow Langmuir adsorption isotherm. Adsorption mechanism involves both physisorption and chemisorptions. The surface study of inhibited mild steel was performed by scanning electron microscopy (SEM).
