Extraction and preconcentration of trace Al and Cr from vegetable samples by vortex-assisted ionic liquid-based dispersive liquid-liquid microextraction prior to atomic absorption spectrometric determination
(ELSEVIER SCI LTD, 2018)
In the study, a simple, and efficient microextraction approach, which is termed as vortex-assisted ionic liquid-based dispersive liquid-liquid microextraction (VA-IL-DLLME), was developed for flame atomic absorption ...
Improvement in intersubband optical absorption and the effects of device parameter variations in quantum wells with an applied electric field
(ACADEMIC PRESS LTD, 1999)
The intersubband optical absorption in symmetric and asymmetric, single and coupled, double GaAs/Ga1-xAlxAs quantum wells is calculated. The results have been obtained in the presence of a uniform electric field as a ...

Objective: The purpose of this article is to determine nurses' and paediatricians' knowledge regarding the sleeping positions and environment of infants. Methods: This descriptive and cross-sectional study was conducted ...
Benchmark results for natural and mixed convection heat transfer in a cavity
(EMERALD GROUP PUBLISHING LTD, 2015)
Purpose - The purpose of this paper is to numerically investigate steady, laminar natural and mixed convection heat transfer in a two-dimensional cavity by using a finite volume method with a fourth-order approximation of ...
Effect of various bridging liquids on coal fines agglomeration performance
(ELSEVIER SCIENCE BV, 2001)
Oil agglomeration is a surface property based on the differences in the surface properties of the organic and inorganic constituents of coal. A bituminous coal was agglomerated using kerosene, diesel oil, Kirkuk Crude ...
In Vitro Release Kinetics of Bovine Serum Albumin from Highly Swellable Dextran Hydrogels
(WILEY, 2010)
Hydrogels synthesized from a polysaccharide-based polymer, dextran, in the presence of two crosslinking agents, N,N'-methylenebisacrylamide and epichlorohydrin, were evaluated for the oral colon-specific delivery of ...
POSTOPERATIVE RETENTION OF URINE IN GENERAL SURGICAL PATIENTS
