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 ...

(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 ...
Use of triticale alone and in combination with wheat or maize: effects of diet type and enzyme supplementation on hen performance, egg quality, organ weights, intestinal viscosity and digestive system characteristics
(ELSEVIER SCIENCE BV, 2003)
An experiment was conducted to investigate the effects of triticale in laying hen diets when used alone or in combination with maize or wheat, and with or without enzyme supplementation on hen performance, egg quality, ...
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 ...
