A New Ultrasonic Thermostatic-Assisted Cloud Point Extraction/Spectrophotometric Method for the Preconcentration and Determination of Bisphenol A in Food, Milk, and Water Samples in Contact with Plastic Products
(SPRINGER, 2017)
Bisphenol A (BPA) contamination in foods and beverages usually occurs as a result of migration from the packages that contain it. In this context, a simple, easy-to-use, and efficient method was developed for the ...
The effect of various treatment conditions on natural zeolites: Ion exchange, acidic, thermal and steam treatments
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
Two different natural zeolites having different phase compositions were obtained from different regions of Turkey and modified by ion-exchange (0.5 M NH4NO3) and acid leaching using 1 M HCl. The natural and modified samples ...
Relief of Pain During Blood Specimen Collection in Pediatric Patients
(LIPPINCOTT WILLIAMS & WILKINS, 2012)
Purpose: To investigate the effect of external cold and vibration stimulation via Buzzy (R) on pain and anxiety levels of children during blood specimen collection. Study Design and Methods: This study was a randomized ...
Synthesis, spectral analysis and quantum chemical studies on molecular geometry, chemical reactivity of 7-chloro-9-(2 '-chlo rophenyl)-2,3-dihydroacridin-4(1H)-one and 7-chloro-9-(2 '-fluo rophenyl)-2,3-dihydroacridin-4(1H)-one
(ELSEVIER SCIENCE BV, 2017)
7-Chloro-9-(2'-chlorophenyl)-2,3-dihydroacridin-4(1H)-one (3a) and 7-chloro-9-(2'-fluorophenyl)-2,3dihydroacridin-4-(1H)-one (3b) were synthesized from 2-amino-2',5-dichlorobenzophenone (1a) and 2-amino-5-chloro-2'-fluor ...
Evaluation of surface roughness and bond strength of quartz fiber posts after various pre-treatments
(INFORMA HEALTHCARE, 2014)
Purpose. Debonding at the post-adhesive interface is a major problem for quartz fiber posts. The objective of this study was to evaluate surface roughness and bond strength of quartz fiber posts after various surface ...
Neuroprotective Activity of Cannabinoid Receptor-2 Against Oxidative Stress and Apoptosis in Rat Pups Having Experimentally-Induced Congenital Hypothyroidism
(WILEY, 2017)
In this study, it was aimed to show the cannabinoid receptor-2 (CB2) role, which is a part of neuroprotective endocannabinoidal system, against increasing nitric oxide synthetase (iNOS, eNOS) levels and the apoptotic ...
The Effects of Nigella Sativa Seed Extract on Bone Healing in an Experimental Model
(LIPPINCOTT WILLIAMS & WILKINS, 2016)
The purpose of this study was to histologically evaluate the effects on bone healing of nigella sativa seed extract applied on calvarial defects in an ovariectomized rat model. The study included 32 female rats weighing ...
Experimental determination of interfacial energy for solid Al in the Al-Sn-Mg eutectic system with Bridgman-type apparatus
(ELSEVIER SCIENCE BV, 2019)
The equilibrated grain boundary groove shape of solid Al in equilibrium with Al-Sn-Mg eutectic liquid was observed by using a Bridgman type directional solidification apparatus. The ratio of the thermal conductivity of the ...
FOURTH GENERATION LEPTONS SEARCH IN gamma gamma -> l(-) l(+) PROCESS AT THE CERN-LHC
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2011)
The pp. pXp production is known to be one of the cleanest channels at the Large Hadron Collider (LHC). In this work, we investigate the potential of the exclusive pp -> pl(-) l(+) p process to probe fourth family leptons ...
