Hydro ontologies are digital artifacts that contain representations of hydrological entities. They are being constructed to advance interoperability within and between all kinds of water data networks. Increased growth of such networks, however, requires integration of a greater variety of data, which requires a more general and principled approach to hydro ontology. One such approach is the de...

This study presents analysis of pico-hydro electrical power plant in North Sulawesi, Indonesia. The objective of this study is to get a design of axial turbine pico-hydro electrical power plant. The method used the study of literature, survey the construction site of the power plant and the characteristics of the location being a place of study, analysis of hydropower ability and analyzing cost...

The title compound, C(17)H(18)NO(+)·I(-), is an adduct resulting from an intra-molecular Diels-Alder reaction of methallyl chloride with 3,4-dihydro-1-furylisoquinoline. The cation comprises a fused penta-cyclic system containing three five-membered rings (dihydro-pyrrole, dihydro-furan and tetra-hydro-furan) and two six-membered rings (tetra-hydro-pyridine and benzene). The five-membered rings...

The purpose of this study was to examine histologically the effects of propolis topical application to dental sockets and skin wounds. After topical application of either a 10% hydro-alcoholic solution of propolis or 10% hydro-alcoholic solution alone, cutaneous wound healing and the socket wound after tooth extraction were examined. The rats were sacrificed at 3, 6, 9, 15 and 21 days after the...

Microwave-assisted hydro distillation MAHD of eucalyptus citriodora. oil was investigated and a comparison was made with conventional hydro distillation. For MAHD, three process parameters; Microwave power, Extraction time and duration of dryness of sample were selected for the extraction. MAHD resulted in a shorter extraction time and better quality of oil compared to that in conventional hydr...

POWER ENGINEERING JOURNAL APRIL 2002 61 I nduction generators are commonly used for small hydro schemes due to advantages such as availability, low cost and robustness. The cost per kW of a single-phase generator is generally higher than a threephase generator. Hence a three-phase generator, which produces a single-phase output, is normally used. In order to minimise further the capital cost, c...

Understanding the teleconnections between hydro-meteorological data and the El Niño–Southern Oscillation cycle (ENSO) is an important step towards developing flood early warning systems. In this study, the concept of mutual information (MI) was applied using marginal and joint information entropy to quantify the linear and non-linear relationship between annual streamflow, extreme precipitation...

The primary aim of this paper is to provide background information, motivation for applications and an exposition to the methodologies employed in the development of fuzzy logic based decision making in hydro or water power engineering by optimum selection of hydro turbine blade material. All the works on the application of multi criteria decision analysis (MCDA) or fuzzy logic to material scie...

BACKGROUND Electronic "cigarettes" are marketed to tobacco users as potential reduced exposure products (PREP), albeit with little information regarding electronic cigarette user toxicant exposure and effects. This information may be obtained by adapting clinical laboratory methods used to evaluate other PREPs for smokers. METHODS Thirty-two smokers participated in four independent Latin-squa...
