Shear flocculation of fine hematite particles and correlation between flocculation, flotation and contact angle
(ELSEVIER SCIENCE SA LAUSANNE, 1997)
This paper presents a study on the shear flocculation of fine (38 mu m) hematite using dodecylamine acetate and Aero 801 (a mixture of petroleum sulfonate and mineral oil) as collectors. The effects of pH, collector ...
Superficial wound disruption after cesarean delivery: Effect of the depth and closure of subcutaneous tissue
(WILEY, 1997)
Objective: The aim of this study was to determine the effect of the depth of subcutaneous tissue at the operative site and the closure of subcutaneous tissue on abdominal wound disruption after cesarean delivery. Methods: ...
The role of transvaginal sonography in predicting recurrent preterm labour in patients with intact membranes
(ELSEVIER SCI IRELAND LTD, 1997)
Our purpose was to determine whether funnelling of the cervical internal os, length of the endocervical canal, cervical index, funnel length and funnel width determined by transvaginal sonography are predictive of recurrent ...
The determination of additive effect and intraocular pressure lowering effects of 0.05% bromocriptine and 0.25% timolol
(KLUWER ACADEMIC PUBL, 1997)
It has been confirmed that topically applied bromocriptine has a satisfactory intraocular pressure (IOP) lowering effect without serious ocular or systemic side effects. We compared the IOP lowering effects of 0.05% ...
The orbit centre dependence of the energy levels in a single quantum well under external titled magnetic and electric fields
(IOP PUBLISHING LTD, 1997)
The: analytical solutions of the Schrodinger equation for a square well system subjected to an externally applied electric field in the growth direction and an externally applied tilted magnetic field are obtained and the ...
Effects of deferoxamine and sympathectomy on endothelin-1-induced contraction and acetylcholine-induced relaxation following subarachnoid hemorrhage in carotid artery
(ELSEVIER SCIENCE INC, 1997)
The role of endothelium-related factors in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH) has gained interest since the discovery of EDRF and of endothelin (ET-1). The effect of SAH and both ...
Serum free carnitine levels in children with recurrent pulmonary infections
(BLACKWELL SCIENCE, 1997)
The serum free carnitine levels of 33 children with recurrent pulmonary infection and 30 healthy children were measured and found to be 26.12 +/- 0.98 nmol/mL and that of the control group 38.98 +/- 0.79 nmol/mL on the ...
Karstification in Miocene gypsum: An example from Sivas, Turkey
(SPRINGER VERLAG, 1997)
In this study, karstification developed in the Miocene gypsum which covers a large area around Sivas, Turkey, the relation between regional tectonics and karstification, and hydrogeological features have been investigated. ...
Collapse dolines in miocene gypsum: An example from SW Sivas (Turkey)
(SPRINGER VERLAG, 1997)
This study investigated the formation mechanism of dolines. Dolines are caused by dissolution of gypsum in the study area, 50-220 m in diameter. Two systems were applied to determine the support necessary for natural ...
An evaluation of the using possibilities of the carbonitrided simple steels instead of carburized low alloy steels (wear properties)
(ELSEVIER SCIENCE BV, 1997)
In this study, the wear behaviour of carburized and carbonitrided AISI 1020 and 5115 steels, widely used in industry, were investigated. The surface properties, microstructures, hardness distributions and wear behaviour ...
