The title compound, C(18)H(16)O(2), was prepared by reduction of 2-(5,6,7,8-tetra-hydro-2-naphtho-yl)benzoic acid with zinc dust. The benzene ring in the tetra-hydro-naphthyl substituent is nearly perpendicular to the plane of the isobenzofuran-1(3H)-one ring [87.15 (4)°]. The cyclo-hexane unit has a half-chair conformation in which two methylene groups in the tetra-methyl-ene bridge are disord...

This paper presents a hydraulic hybrid vehicle drive train to improve the fuel efficiency of a passenger car. The developed hydro-mechanical drive train enables independent control of the torque at each wheel. The motivation for developing this drive train is a hydraulic hybrid vehicle test bed for the Center for Compact and Efficient Fluid Power at the University of Minnesota. The hydro-mechan...

This research presents an integrated system of computer software, networking and web-based display developed and deployed to allow drainage management authorities immediate access to results from the Weather Research and Forecasting (WRF) Hydrological Extension model, WRF-Hydro. Output data from the model are analyzed by a chain of GIS, database and web publishing tools to forge updated and rea...

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...

Introduction: Regarding chronic nature of epilepsy and its side effects and to access the effective treatment procedures, herbal medicine has received remarkable interest. The aim of this study was to determine the anticonvulsant effects of hydro-alcoholic extract of Anethum graveolens seed on pentylenetetrazol (PTZ) -induced seizure in male mice. Methods: Fifty-six albino male mice were div...
