Shaping ability of reciprocating single-file and full-sequence rotary instrumentation systems in simulated curved canals
(2015)
Objective: The purpose of this study was to evaluate the shaping ability of three nickel-titanium systems in simulated curved canals. Materials and Methods: Sixty simulated canals were prepared to apical size 25 with ...
A comparison of standard and retrospective pre-post testıng for measuring the changes in science teaching efficacy beliefs
(2015)
Thirty-nine American and 78 Turkish preservice elementary teachers’ personal science teaching efficacy (PSTE) beliefs were investigated during science methods courses with standard and retrospective pre-post testing methods. ...
Response surface modelling for reactive dye removal using bio-solids: Application of box-behnken experimental design
(2015)
The removal of reactive dyes is rather difficult by chemical coagulation/flocculation because of strong resistance to biodegradation in aerobic environments. The removal of color from textile wastewater using low-cost ...
Notes on near-ring ideals with (?, ?)-derivation
(2015)
In the present paper, we extend some well known results concerning derivations of prime near-rings in [4], [5] and [13] to (?; ?)– derivations and semigroup ideals of prime near-rings. © 2015, Hacettepe Journal of Mathematics ...
Antioxidant activity of five Lathyrus L. Species growing in Turkey [Türkiye’de yetişen beş Lathyrus L. Türlerinin antioksidan etkileri]
(2015)
The antioxidant activities of five Lathyrus species growing in Turkey were investigated by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay and the contents of total phenolics in the extracts were ...
Effects of different cavity disinfectant procedures on microtensile bond strength of permanent teeth
(2015)
Objectives: The aim of this study was to compare the effects of different cavity disinfectants and KTP laser applied before/after acid-etching on microtensile bond strength of a composite resin to permanent teeth. The ...
Indirect Determination of Free, Total, and Reversibly Bound Sulfite in Selected Beverages by Spectrophotometry Using Ultrasonic-Assisted Cloud Point Extraction as a Preconcentration Step
(2015)
A new indirect ultrasonic-assisted cloud point extraction (UA-CPE) method has been developed for the determination of trace sulfite species by means of spectrophotometry. The method is based on either directly imide–bisulfite ...
The Investigation of Acanthamoeba and Other Free Living Amoeba in Swab Samples Obtained from Conjunctiva and Eye Lid [Göz Kapaklarından ve Konjunktivadan Alınan Sürüntü Örneklerinde Acanthamoeba ve Diğer Serbest Yaşayan Amiplerin Araştırılması]
(2015)
OBJECTIVE: In the study, it is aimed to determine the prevalence of Acanthamoeba and other free-living amoeba (FLA) species in the swab samples obtained from conjunctiva and lower eye lid.METHODS: For this purpose, swab ...
An impulsive Sturm-Liouville problem with boundary conditions containing Herglotz-Nevanlinna type functions
(2015)
In this article, an impulsive Sturm-Liouville boundary value problem with boundary conditions contain Herglotz-Nevanlinna type rational functions of the spectral parameter is considered. It is shown that the coefficients ...
A new micellar mediated cloud-point extraction procedure for sensitive and selective determination of trace amounts of total iodine in Milk-based nutritional products by means of indirect spectrophotometry
(2015)
A new micellar mediated cloud-point extraction procedure (CPE) has been developed for sensitive and selective determination of trace amounts of total iodine by means of indirect spectrophotometry. The method is based on ...
