Effects of Hypericum perforatum L and Hypericum calycinum L extracts on the central nervous system in mice
(Gustav Fischer Verlag, 1996)Hypericum species have been used as herbal remedies for the therapy of various diseases since ancient times. It has been reported that Hypericum perforatum is a useful herbal remedy for the treatment of neurological disorders ... -
Expansions and contractions of hybrid systems
(I E E E, 1997)Inclusion and extension principles are defined and studied for hybrid systems. The controller design problem for hybrid systems is then considered within the framework of the extension principle. It is shown that if the ... -
Stabilization of petroleum contaminated drilling wastes by additives
(International Society Offshore& Polar Engineers, 1997)Petroleum industry has resulted in the release of large quantities of waste containing a variety of organic and inorganic pollutants, During the petroleum production, petroleum contaminated drilling muds and cuttings were ... -
An intelligent control approach to decentralized routing and flow control in highways
(I E E E, 1997)A decentralized intelligent controller for routing in multi-destination transportation networks is presented. The controller is based on a dynamic congestion measure which was recently derived from the solution of an optimal ... -
A game theoretic approach to the optimal control of uncertain systems
(Pergamon-Elsevier Science LTD, 1996)The issue of performance robustness is considered in a dynamic games framework where the god is to find a feedback controller that stabilizes the system under all plant perturbations and that minimizes the value of a ... -
Electrocoagulation for oil-water emulsion treatment
(Taylor & Francis Inc, 1997)An attempt has been made to remove oil from synthetic and actual oily wastes by an electrochemical method using either iron or aluminum reactors. The effects of applied potential i.e direct current, reactor material and ... -
Electrodialysis for the removal of copper ions from wastewater
(Taylor & Francis Inc, 1997)In this work,the feasibility of the removal of Cu2+ ions in a model solution and a sample of rinse water have been studied using a recirculating electrodialysis system. Full removal of Cu2+ has been achieved from its dilute ... -
Flow-through spectrophotometric determination of omeprazole in pharmaceutical preparations containing enteric coated pellets
(Govi-Verlag Pharmazeutischer Verlag GMBH, 1997)… -
Effects of Ni(II) on respirometric oxygen uptake
(Springer Verlag, 1997)The effects of Ni(II), substrate and initial biomass concentrations on biochemical oxygen demand (BOD) were studied by using an electrolytic respirometer. The effects of Ni(II) (2.5, 5.0, 10.0, 25.0 mg/l) and substrate ... -
Metal-ceramic interface characterisation of capacitor-discharge joined alumina
(IOP Publishing LTD, 1999)Capacitor discharge joining of ceramics offer bonding without the damaging effects of extended heating times. Microstructures formed in alumina-AlxNiyYz -alumina joints were investigated using a combination of EDX and PEELS ... -
Critical factors in the templated grain growth of textured reaction-bonded alumina
(Wiley-Blackwell, 2000)The Templated Grain Growth (TGG) of Al2O3 occurs in three stages: densification, radial growth of individual template grains until template impingement, and template grain thickening. Significant template growth occurs ... -
Seeding of the reaction-bonded aluminum oxide process
(Wiley-Blackwell, 2001)The effect of the initial alpha -Al2O3 particle size in the reaction-bonded aluminum oxide (RBAO) process on the phase transformation of aluminum-derived gamma -Al2O3 to alpha -Al2O3, and subsequently densification, was ... -
The chemical durability of SrO-MgO-ZrO2-SiO2 glasses in strongly alkaline environments
(Elsevier Sci LTD, 2000)A large region of glass formation was found in the system SrO-MgO-ZrO2-SiO2 and some properties have already been reported. Detailed studies have shown that glasses with only 40 wt% silica unusually durable in 1 M NaOH and ... -
Thermal shock parameters [R, R ''' and R ''''] of magnesia-spinel composites
(Elsevier Sci LTD, 2003)Thermal shock parameters (R, R'" and R"") have been calculated using measured strength and modulus values for model magnesia-spinel composite materials. The R'" and R"" parameters vary with both spinel content (0-30%) and ... -
The impact of financial system development on business cycles volatility: cross-country evidence
(Louisiana State University Pr, 2002)This paper reveals cross-country evidence on how the development of the financial system affects business cycle's volatility. The link between credit markets and economic activity has been the focus of extensive literature, ... -
Research of usability of tree leaves and soil in determining the contribution of industry and traffic to air pollution in Bozuyuk (Turkey) region.
(Triveni Enterprises, 2003)In industrialized regions like Bozuyuk, generally density of settlement and traffic is also observed. As a result of this density, the metal pollution that results from either industrial activities or traffic shall affect ... -
Work of fracture and fracture surface energy of magnesia-spinel composites
(Elsevier Sci LTD, 2003)This study used a model system of fully dense high purity magnesia, incorporating fine grain spinel prepared by hot-pressing. Work of fracture (gamma(WOF)) and fracture surface energy (gamma(i)) were determined to be a ... -
Magnesia-spinel microcomposites
(Elsevier Sci LTD, 2004)This study used a model system of fully dense high purity MgO, incorporating micron size spinel prepared by hot-pressing. Spinel powder was obtained from two sources: (i) 0.5 mum alumina powder was incorporated into MgO ... -
An application for zirconia as a pharmaceutical die set
(Elsevier Sci LTD, 2004)The main objective of this study was to investigate the possible use of zirconia as a material for the manufacture of punches and dies for use in tableting machines and to study its effect on ejection of tablets made from ...
