Parametric Studies of Carrot Seed Oil Extract for the Production of Medicated Soap

Authors: Abdulrasheed A., Aroke U.O., Sani I. M.

Abstract— The research is to investigate the possible use of Carrot seed oil extract in the production of medicated soap. The oil extraction from Carrot seed was achieved through Soxlet extraction method. Carrot seed contains high carotene, a major pigment of carrot and enhancer of LOPS microbial activity as reported by Hayashi et al. (2013). Some physicochemical properties of the oil were analysed and they were found within specifications except for its boiling point which was found to be 134oC, below the specified boiling point range of 150oC to 300oC for essential oils as reported by Ranken et al (1997). The soap produced gave a pH of 7.4, foam height (4.8 cm), alcohol insoluble (6.0%), moisture content (9%). The antifungal activity of the soap fortified with Carrot seed oily extract on Trichophyton rubrum shows a very good sensitivity of 24.1 mm a bit below that of the Standard soap (26.6 mm) and above that of the Control soap (8.0 mm). From the analysis of the soap produced, it can be concluded that a highly effective medicated soap can be produced from Carrot seed extract.

Keywords—Carotene, Carrot seed, Carrot seed oily extract, Medicated soap, Trichophyton rubrum.

Modal Analysis of Cantilever Beam with T-Section using Finite Element Method

Authors: Sampath S S, Sawan Shetty, Chithirai Pon Selvan M

Abstract— This paper deals with the vibration characteristics of a beam. A modal analysis is carried out on a cantilever beam with T section. The beam is modeled, designed and analyzed in in finite element analysis software ANSYS. The cantilever beam which is fixed at one end is vibrated to obtain the nature of vibration. All the degrees of freedom on the free end are taken into account. Modes and the natural frequencies pertaining to it are computed in finite element analysis software.

Keywords— Cantilever beam, ANSYS, modal analysis, degrees of freedom.

Effect of Fly Ash in PPC Concrete

Authors: Parveen, Vivek, Bhupinder Singh

Abstract-- The era of infrastructure increased in recent year, so the advancement of concrete technology exaggerated day by day in life. Use of concrete exaggerated the consumption of natural resources and energy sources. In recent years, inordinate measure of fly ash is generated in thermal industries. The previous couple of years, some cement firms have started mistreatment ash in producing cement called hydraulic cement, however, the utilization of ash remains terribly low. There’s intolerably opportunity for the fly ash in cement likewise as in concrete. This work describes the use of Non-conventional artifact (Fly ash) that is definitely out there. During this work cement and fine aggregate has been partly replaced by fly ash consequently within the range of 0% (without fly ash), 10%, 20%, 30%, 40% and 60% by weight of cement for M-25 Mix Concrete mixtures were molded, tested and compared in terms of compressive and split strength.
