The report continues reporting of results of an ongoing research verifying a hypothetic energy generation mechanism for reengineering of Gritskevich’s Hydro Magnetic Dynamo (HMD). The HMD technology is a patented technology for electric power generation. It was invented in Russia and deployed in a semi-industrial scale (1.5 MW power unit) in Armenia in 1992. After its successful exploitation during 5 years no more units were assembled. Nowadays the technology needs verification of its physical mechanisms for its successful reengineering. The aim of the report is to present current results of an ongoing theoretical and experimental research of hypothetic physical mechanisms providing energy generation in the unit. It is written without disclosure of its construction and technical details. Thus the theory of hypothetic energy generation mechanisms is described in a general way. The reported experimental results provide only partial support for the theory. They should be independently reproduced and verified.

Aims: Determine the variability and usages of Traditional Alkaline Salts (TAS) used in Africa, specifically in Cameroon.

Place and Duration of the Study: This study was done in different agro-ecological areas of Cameroon between January and August 2015.

Methodology: Individual interviews of women (204) found in markets of different Agro-ecological areas of Cameroon (Sudano-sahelian, high Guinea savannah, Western highlands and Humid forest) by using a semi-structured questionnaire.

Results: Traditional Alkaline Salts used in Cameroon are rocks (Lakes’ deposits) and plant-based salts (plant-based ashes, their solutions, their filtrates and evaporites of these filtrates). They are mainly used in food preparations, but also as drugs (rocks only). They are used in food preparations as technological auxiliary (preservatives, emulsifiers, taste improvers, color improvers/maintainers, texture improvers/modifiers) and for biological functionalities (avoidance of stomach distending and stomach cleaning of breastfeeding women).

Conclusion: Diversity of TAS, their functionalities, frequency and level of use, raise up research issues on their chemical composition, the mechanism involved in their properties, their stability and their toxicology risk.

Causal Linkage amongst Public Expenditure on Health, Health Status and Growth: New Empirical Evidence from Toda-Yamamoto Approach for Nigeria

This study investigates the causal linkages amongst public expenditure on health, health status and economic growth in Nigeria using the Toda-Yamamoto technique. The choice of the Toda-Yamamoto approach is predicated on its simplicity and the ability to overcome the shortcomings inherent in the conventional causality procedures by producing more robust results through the estimation of the augmented VAR that guarantees the asymptotic distribution of the Wald statistic. To this end, the study collected annual time series data from the Central Bank of Nigeria’s Statistical bulletin and the World Development Indicator on public expenditure on health, life expectancy, infant mortality and real gross domestic product spanning 38 years from 1981 to 2018. The result of the study’s empirical analysis based on the co-integration test indicates that public health expenditure, health status and economic growth have long-run association. Further, the Toda-Yamamoto causality test result reveals the absence of causality between health expenditure and health status. Similarly, health status and economic growth are not causally interdependent. On the basis of the findings, the paper vehemently concludes that efforts to stimulate economic growth by targeting health outcomes improvement through public expenditure will be futile. As such, there is the need to develop better national health policy and programmes such as compulsory national health insurance that is capable of resolving the fundamental problems in the health sector. This would help integrate healthcare into the mainstream of the Nigerian economy.

Flooding is a regular annual disaster in Jakarta, especially in December to February. Geographical position of Jakarta which is 40% below sea level, causes flooding not only from rain, but also from rob due to rising sea levels. In the last 5 years the impact of flooding became more serious, leading to economic and human losses.

This study aims to determine the right strategy of flood mitigation by public involvement in the digital era. The method used includes combination of quality input data from experts representing BNPB (National Disaster Agency), Local Goverment, Academics, Community Leaders, Businessmen, and Practitioners, in addition to vulnerable field research. Data analysis uses the ECM (Exponential Comparison Method) and SAST (Strategic Assumption Surfacing and Testing).

The result of the study indicates that the most appropriate strategy to mitigate flood disaster is establishment of “Disaster Information Center” and "Disaster alert groups” involving every stakeholder from the community. Utilization of social media, especially WhatsApp, Facebook, and Instagram has been very helpful to share information of flood, especially how to prepare an emergency action to reduce economic and human losses.

Experimental Determination of Panel Generation Factor for Apo Area of Federal Capital Territory in Nigeria

The nature of renewable energy resources makes it necessary to perform site-specific resource assessment in order to achieve fairly accurate estimate of energy harvest so as to meet requirements of energy consumption and storage. Available design tools are based largely on remote modeling and estimation of site’s resource potentials. These design tools provide analytical value of the panel generation factor which may not represent the true value. The panel generation factor is used for design of solar photovoltaic systems. This paper reports on the panel generation factor obtained from experimental determination of its value for Apo Area of the Federal Capital Territory in Nigeria. The value of the panel generation factor obtained experimentally for Apo Area is 3.625. The panel generation factor reported in literature for tropical climate of Apo is 3.596. The value obtained for the experimentally determined panel generation factor represents a deviation of 0.88% in comparison with the value reported in literature, validating the value obtained experimentally. The site-specific requirement of renewable energy deployment is indicative of the usefulness of this experimentally determined panel generation factor.
