Surface modification of electrospun cellulose acetate nanofibers via RAFT polymerization for DNA adsorption
(ELSEVIER SCI LTD, 2014)
We report on a facile and robust method by which surface of electrospun cellulose acetate (CA) nanofibers can be chemically modified with cationic polymer brushes for DNA adsorption. The surface of CA nanofibers was ...
A retrospective analysis of the relationship between rhinosinusitis and sinus lift dental implantation
(BMC, 2014)
Introduction: Dental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. ...
Electrochemistry and determination of cefdinir by voltammetric and computational approaches
(FOOD & DRUG ADMINSTRATION, 2014)
The oxidation and reduction behavior of cefdinir (CEF) was studied by experimental methods and computational calculations at B3LYP/6-31+G (d)//AM1. Voltammetric studies were carried out based on two irreversible reduction ...
Cyclodextrin-grafted electrospun cellulose acetate nanofibers via "Click" reaction for removal of phenanthrene
(ELSEVIER SCIENCE BV, 2014)
Beta-cyclodextrin (p-CD) functionalized cellulose acetate (CA) nanofibers have been successfully prepared by combining electrospinning and "click" reaction. Initially, p-CD and electrospun CA nanofibers were modified so ...
ACHENE MICROMORPHOLOGY OF SEVEN TAXA OF ACHILLEA L. (ASTERACEAE) FROM TURKEY
(BANGLADESH ASSOC PLANT TAXONOMISTS, 2014)
Micromorphological characters of achenes in seven taxa of Turkish Achillea L. (Asteraceae) were investigated using stereomicroscope and scanning electron microscope (SEM). Some morphological descriptions of achenes were ...
Ellenberg's indicator values for soil nitrogen concentration and pH in selected swamp forests in the Central Black Sea region of Turkey
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2014)
Ellenberg developed a system that assigns indicator scores for habitat characteristics of individual plant species. Swamp forests are highly diverse ecological communities and include different plant species, all of which ...
An Investigation Of Using Video Vs. Audio For Teaching Vocabulary
(ELSEVIER SCIENCE BV, 2014)
Integrating technology in classroom has become one of the most discussed issues in language teaching environments since 1920s. Video, being one of the frequently used instruments, became widely available as a teaching ...
Generalized alpha-psi contractive mappings in quasi-metric spaces and related fixed-point theorems
(SPRINGEROPEN, 2014)
In this paper, we characterize alpha-psi contractive mappings in the setting of quasi-metric spaces and investigate the existence and uniqueness of a fixed point of such mappings. We notice that by using our result some ...
The applicability of the "Sniffin' Sticks" olfactory test in a Turkish population
(INT SCIENTIFIC LITERATURE, INC, 2013)
Background: Olfactory assessment is often neglected in clinical practice, although olfactory loss can assist in diagnosis and may lead to significant morbidity. "Sniffin' Sticks" is a modern test of nasal chemosensory ...
A note on common fixed points for (psi, alpha, beta)-weakly contractive mappings in generalized metric spaces
(SPRINGER INTERNATIONAL PUBLISHING AG, 2013)
Very recently, Isik and Turkoglu (Fixed Point Theory Appl. 2013:131, 2013) proved a common fixed point theorem in a rectangular metric space by using three auxiliary distance functions. In this paper, we note that this ...
