Polyelectrolyte CASA hydrogels for uptake of uranyl ions from aqueous solutions
(JOHN WILEY & SONS INC, 2007)
In this study, uranyl ion adsorption from aqueous solutions has been investigated by chemically crosslinked acrylamide/sodium acrylate (CASA) hydrogels. Adsorption studies were investigated by the spectroscopic method. ...
The association of biomass fuel combustion on pulmonary function tests in the adult population of Mid-Anatolia
(BIRKHAUSER VERLAG AG, 2004)
Objectives: To assess the association of biomass as domestic energy source on respiratory function in rural areas of Mid-Anatolia in Turkey where biomass use is frequent. Methods: In a cross-sectional study, pulmonary ...
Surface roughness of new microhybrid resin-based composites
(AMER DENTAL ASSOC, 2005)
Background. Rough, poorly polished resin-based composite (RBC) surfaces contribute to staining, plaque accumulation, gingival irritation and recurrent caries. Proper finishing and polishing enhance both the esthetics and ...
Biological denitrification of drinking water in a slow sand filter
(ELSEVIER SCIENCE BV, 2007)
Biological removal of nitrate from drinking water was studied in a slow sand filter. Optimum carbon to nitrogen ratio (C/N) was found to be 1.8 when using acetic acid in batch tests. The filtration rates impact on NO3-N ...
Relationship between FIGO grade and AgNOR, S100-positive Langerhans cells in endometrial adenocarcinoma
(WILEY, 2000)
Cell kinetic information is an important adjuvant to histological grading in some malignant tumors. In the current study, 20 endometrial adenocarcinomas were graded according to the 1988 International Federation of Gynecology ...
Histological examination of ovarium development of shemaya Chalcalburnus chalcoides living in Lake Todurge (Sivas/Turkey)
(INST VERTEBRATE BIOLOGY AS CR, 2004)
The process of oogenesis of C. chalcoides living in Lake Todurge was histologically studied from monthly samples during April-November 2000. The process was divided into five stages (previtellogenic, cytoplasmic growth, ...
Inverse scattering problem for the Schrodinger-type equation with a polynomial energy-dependent potential
(IOP PUBLISHING LTD, 2006)
In the present paper the inverse scattering problem for the Schrodinger-type equation with a polynomial energy-dependent potential is investigated on the entire real line (-infinity; +infinity). The scattering data of the ...
Adsorption of methyl violet in aqueous solutions by poly(acrylamide-co-acrylic acid) hydrogels
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
In this study, Acrylamide(AAm)/Acrylic Acid(AAc) monomer mixtures which contain different quantities of acrylic acid have been irradiated to form hydrogels with gamma-radiation. Acrylamide/Acrylic Acid (AAm/AAc) monomer ...
A basal chalcidoid (Insecta : Hymenoptera) from the earliest Cretaceous or latest Jurassic of Mongolia
(BRILL ACADEMIC PUBLISHERS, 2004)
Khutelchalcis gobiensis gen. et sp. n. (Khutelchalcididae fam. n.), based on a tiny impression fossil collected from the lowermost Cretaceous or uppermost Jurassic deposits of Khutel-Khara in East Mongolia, was studied ...
Mechanism of relaxation induced by nicotine in normal and ovalbumin-sensitized guinea-pig trachea
(ELSEVIER SCIENCE BV, 2007)
Nicotine is an irritant molecule in the cigarette that contributes airway hyper-reactivity. The aim of this study was to investigate the mechanism of these effects and effects of nicotine on the isolated trachea preparations ...
