Development of a low-cost mass culture media for Spirulina platensis
A.C.W.W.M.C.L.K.Coswatte, K.S.P.Munirathna, Chamoda Dissanayake and S.C.jayamanne

Abstract: The commercial production of Spirulina sp. has gained worldwide attention due to the fact that they have high nutritional value to be used as a human food supplement. This study aimed to develop a low-cost mass culture media for Spirulina platensis in Sri Lanka for commercial purposes. This study was carried out in three axenic culture media (T1, T2 and T3) by substituting selected fertilizers and cost-effective alternative chemicals in the Zarrouk medium.

STRATEGIES FOR ENHANCING STUDENTS PRACTICAL SKILLS ACQUISITION IN ELECTRICAL INSTALLATION AND MAINTENANCE WORK IN TECHNICAL COLLEGES IN RIVERS STATE, NIGERIA
Nwauzi K. K., Azubuike Ovundah, Kingsley C.Anah

Abstract: The study was carried out to determine strategies for enhancing student practical skills in Electrical Installation and Maintenance Work in Technical Colleges in River’s State. A descriptive Survey was used for the study. The population for the study was 48 Electrical teachers and 12 administrators in technical colleges in River’s state. The study was carried out in River state. A structured questionnaire was used as instruments for data collection. two research questions and tow null hypotheses guided the study. Cronbach Alpha method was used for the reliability of the instrument which yielded a coefficient of .75 validity of the instrument. Mean and standard deviation were used to analyze the data for answering research questions while t- test was used to test the hypotheses of no significant difference at .05 level of significance.

Numerical Analysis of the Turbulent Flow around DTMB 4381 Marine Propeller
Kyaw Kyaw, Ye Jinming

Abstract: This article presents a numerical analysis of a turbulent flow past DTMB 4381 marine propeller by the means of RANS approach; the propeller designed at David Taylor Model Basin in USA. For numerical evaluation of propeller open-water characteristics, the moving reference frame approach was used. Total force and moment acting on blades, as well as average force distributions in one revolution on propeller disk, are obtained for each case of advance ratio (J). The solver used in this study was the commercial package Star-CCM+ from SIEMENS. The computed results are compared with available experimental data and discussed.

The Digital Clinic: A New Developed way for diagnosis and medication
Hossam Mohamed Abdelfattah Saber, Yousef Ahmed Mahmoud Sobhi

Abstract: When it comes to health, we see an evident carelessness from individuals in their health regulation that might interrupt their daily life routine and make them prone to dangerous diseases or even death. The reasons behind this wrong behavior are simple: people do not have time to care about their health due to heavy workload. Moreover, costly, complicated checkups contributed to that action as well. Health-Related research found that approximately 2000 people died monthly because of their medical negligence. As a result, this issue must be treated with a low-cost and efficient solution. In turn, this solution has to provide a formatted environment for patients or individuals to give enough care of their health insurance. Our initial idea is to construct a highly efficient health application that helps people track and monitor their health data and give them guaranteed tips to improve their health state to avoid bad habits or myths. The visualization of data in the android application provides the user with a comprehensive conclusion that devoid of any complexity. By using an integrated network of sensors controlled via microcontrollers, it is now possible to process those data without any difficulty. This system can sense body temperature, humidity, blood pressure, glucose rate, and respiration rate.

DETERMINATION OF ANTIBACTERIAL PROPERTIES OF MEDICAGO SATIVA L. (ALFALFA) EXTRACTS
Miss Anila Ghani, Asma Rehman

Abstract: Alfalfa, also called lucerne and called Medicago sativa in binomial nomenclature, is a perennial flowering plant in the legume family Fabaceae.Antibacterial activity of different solvent extracts of medicinal plant Medicago Sativa Leaves ,Root and Stem against clinical pathogen of human origin was find out.The antimicrobial activity of different solvents crude extract of Medicago Sativa plant root,stem and leaves was tested by disc diffusion and turbidity assay method against four bacterial pathogens E coli,S.typhi,K.pneumoniae and S aureous.After the result it showed that the antibacterial activity of the medicago sativa extract were increased with the increasing concentration of the crude extracts and polarity of the solvents used for extraction.
