The hydrostatic pressure and temperature effects on hydrogenic impurity binding energies in GaAs/InxGa1-xAs/GaAs square quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
We have calculated the ground state binding energy using variational methods and the effective mass approximation for the hydrogenic impurity in square quantum well structure made up of GaAs/InGaAs/GaAs epilayers under the ...
Cyclopertorbitolites, a new soritid (Foraminifera) from the Lower Eocene of the EskiAYehir and Kastamonu regions (Turkey)
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2010)
The Lower Eocene sediments in the southwestern Seyitgazi (EskiAYehir) region include shallow-water rhythmic deposition of claystones, limestones, clayey limestones, and sandy limestones. The Lower Eocene unit in the ...
In vitro fracture resistance of root-filled teeth using new-generation dentine bonding adhesives
(BLACKWELL PUBLISHING LTD, 2003)
Aim To compare the fracture resistance of root-filled premolar teeth restored with new-generation dentine bonding adhesives. Methodology Sixty extracted single-rooted human maxillary premolar teeth were used. Access cavities ...
Analysis of dragline cycle time components
(PLEIADES PUBLISHING INC, 2012)
This paper focuses on the breakdown of dragline cycle time. A 15-year old dragline deployed for casting the interburden and extracting the coal seam immediately beneath is monitored for a period of 45 days. The following ...
Kinetics of fine wet grinding in a laboratory ball mill
(ELSEVIER SCIENCE SA, 2001)
The kinetics of batch wet grinding of quartz from a feed of 600 x 425 mum to a product of 80% less than 8 mum have been determined using sieving and laser diffractometer sizing for size analysis. A dispersing agent was ...
Changes in the nitric oxide system of rat myometrium during midgestation and delivery at term
(ACADEMIC PRESS LTD, 1998)
The aims of this study were to investigate whether a nitric oxide (NO) system is present in the pregnant rat myometrium and whether it differentially inhibits myometrial contractility during midgestation and delivery at ...
Effect of Er:YAG Laser Pulse Duration on Shear Bond Strength of Metal Brackets Bonded to a Porcelain Surface
(MARY ANN LIEBERT, INC, 2013)
Objective: The aim of this study was to compare the effect of different Er:YAG laser pulse durations on the shear bond strength (SBS) of metal brackets bonded to porcelain with two different adhesive systems. Background ...
A cost effective parameter for predicting the troponin elevation in patients with carbon monoxide poisoning: red cell distribution width
(VERDUCI PUBLISHER, 2016)
OBJECTIVE: Carbon monoxide (CO) poisoning is very common worldwide. Despite the fact that CO is known to have cardiotoxic effects, as it has non-specific symptoms; cardiotoxicity could easily be overlooked, especially when ...
Determination of Fatty Acid Profiles and Esterase Activities in the Gills and Gonads of Vimba vimba (L., 1758)
(SPRINGER, 2015)
The main purpose of this study was to evaluate the gills and gonads of Vimba vimba in terms of fatty acid composition, esterase activity, and esterase band patterns by native-PAGE method. In this context, C16:0 and C18:1n-9 ...
Selective and single step adsorption of a-lactalbumin from whole cow's milk on hydroxyapatite microbeads
(ELSEVIER SCIENCE BV, 2016)
In this study, newly modified hydroxyapatite microbeads were used to isolate alpha-lactalbumin (alpha-LA) from cow's milk by a single step. Inorganic material, pure hydroxyapatite was embedded in ethylene glycol dimethacrylate ...
