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.

Effects of Combretum obscurum Tul. almond and Carica papaya fruit seeds on intestinal parasites of captive-bred lemurs at the Parc Botanique et Zoologique de Tsimbazaza (PBZT) in the Madagascar
RAZAFIARISOA Berthine, RAZAIARIVELO Christine, RAMAROMILANTO Boromé, RAMAROKOTO Roger

Abstract: Lemurs are among the specific and endemic animals of the mega biodiversity in the Madagascar. However, a large majority of their species is assigned to different degree of threat in the red list of IUCN. Captive bred conservation is one of the mission of the PBZT to ensure the survival of wild endemic animals by their reproduction and in mass education. Netherveless, life in a confinement needs more adaptations compared with life in the natural habitats. Despite a periodic conventional deworming program, worms infestation are frequent and chronic in captivity. They lead to a permanent health problem and require an alternative solution which would not be harmful and not far from the natural habits of the wild animals. In this study, we try to highlight the potential of two plants well-known against intestinal parasites. Combretum obscurum Tul., an endemic plant and an introduced one, Carica papaya are both used in a randomized controlled trial study to appreciate their outcomes on deworming lemurs intestinal parasites. Results are positive: treatment based on the Combretum obscurum Tul. almond and the Carica papaya fruit seeds are proven to be efficacy to deworm intestinal parasites of lemurs. They could be used safely as a complementary treatment as well as conventional deworming medicines. In addition, they are not far from the natural habits of lemurs and are easier to implement with a minimal risk to develop resistance. They may be a secure sustainable alternative solution to deworm captive lemurs.
