Descriptions of two new Early Cretaceous (Hauterivian) ensign wasp genera (Hymenoptera : Evaniidae) from Lebanese amber
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004)
Two new ensign wasp (Hymenoptera: Evaniidae) genera, Protoparevania Deans and Eovernevania Deans, and species, P. lourothi Deans and E. cyrtocerca Deans, are described from the Lebanese amber outcrop of Mdeirij/Hammana. ...
Numerical simulation of the stalled flow within a vaned centrifugal pump
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2004)
The main goal of the present work is to analyse the numerical simulation of a centrifugal pump by solving Navier-Stokes equations, coupled with the 'standard k-epsilon' turbulence model. The pump consists of an impeller ...
Determination of relationships between thermal conductivity and material properties of rocks
(JOURNAL OF UNIV OF SCIENCE AND TECHNOLOGY BEIJING, 2004)
Energy transfer between the adjacent parts of rocks in underground mines is widely influenced by the thermal conductivity of rocks. The relationships between the thermal conductivity and some material properties of rocks ...

Hydrophobicity of chalcopyrite with dithiophosphate and dithiophosphinate in electrochemically controlled condition
(ELSEVIER SCIENCE BV, 2004)
The degree of hydrophobicity of chalcopyrite was determined by contact angle measurements on polished chalcopyrite surface in electrochemically controlled conditions. Results have shown that the increase in solution pH ...
Synthesis, characterization and evaluation of IPN hydrogels for antibiotic release
(TAYLOR & FRANCIS INC, 2004)
We prepared new ternary interpenetrating polymeric networks (IPN) systems containing chitosan, poly(N-vinylpyrrolidone) and poly(acrylamide) polymers. IPNs were synthesized by radical polymerization of acrylamide monomers ...
The effects of Niguldipine pretreatment on cerebral vasospasm after subarachnoid haemorrhage in rabbits
(JOHN WILEY & SONS LTD, 2004)
Several different mechanisms contribute to the pathogenesis of cerebral vasospasm after subarachnoid haemorrhage. Whatever these mechanisms are, the vessel contraction is ultimately induced by an increase of free intracellular ...
Septum cerrahisi sonrasında internal nazal splint ile burun içi tampon kullanımının östaki tüpü fonksiyonuna etkisinin karşılaştırılması
(2004)
Septum cerrahisi sonrasında burun içi tampon uygulanan 26 hasta ile internal nazal splint uygulanan 20 hastanın preoperatif ve postoperatif östaki tüpü fonksiyonları akustik impedansmetri ile incelendi. Burun içi tampon ...
İnsan Hakkındaki Bazı Felsefi Görüşler Üzerine
(2004)
In this study, it is argued that it is still impossible to claim that the human mystery has been solved since the human kind was appeared on earth or was created despite the crucial findings obtained by anthropologists who ...
Investigation of relationship between critical surface tension of wetting and oil agglomeration recovery of barite
(ELSEVIER SCIENCE BV, 2004)
In this study, relationship between the critical surface tension of wetting of barite and agglomeration recovery and also zeta potential depending on pH and amount of collector (Na-oleate) was investigated. For this purpose, ...
