Swelling of iota-carrageenan gels prepared with various CaCl2 content: A fluorescence study
(European Polymer Federation, 2008-01-05)
Iota carrageenan gels prepared with various CaCl2 content were completely dried and then swelled in water vapor. Steady-state fluorescence ( SSF) technique was used to monitor the swelling process of each iota carrageenan ...
On the Origin and Age of the Ariburnu Beachrock, Gelibolu Peninsula, Turkey
(Scientific Technical Research Council Turkey-TUBITAK, 2008-03-13)
The beachrock formation on the Ariburnu coast situated in the Gelibolu Peninsula has been studied by field observation, thin-section interpretation, physicochemical analyses including ICP-AES and SEM/EDS, and OSL dating. ...
Poly (styrene) latex/modified na-activated bentonite nanocomposite films: a fluorescence study
(Elsevier Science BV, 2008-12)
We studied film formation of composites of surfactant-free polystyrene (PS) nanoparticles and modified Na-activated bentonite (MLB), by steady state fluorescence (SSF) technique. The films were prepared from a mixture of ...
Component resolved IR bleaching study of the blue LM-OSL signal of various quartz samples
(Wind-J Wojewoda Publ Co, 2008-01-01)
The present work provides an initial component resolved analysis concerning the effect of infra-red (IR) exposure at elevated temperatures on the blue LM-OSL signal of quartz (stimulated at 470 nm). The study was performed ...
The conformal Penrose limit: back to square one
(IOP Publishing LTD, 2008-08-21)
We show that the conformal Penrose limit is an ordinary plane wave limit in a higher dimensional framework which resolves the spacetime singularity. The higher dimensional framework is provided by Ricci-flat manifolds which ...
LM-OSL thermal activation curves of quartz: Relevance to the thermal activation of the 110 degrees C TL glow-peak
(Pergamon-Elsevier Science Ltd, 2008-01)
The thermally activated characteristics (TAC) of the linearly modulated optically stimulated luminescence (LM-OSL) signals of seven quartz samples from different origin were studied relative to the TAC of their respective ...
Effect of annealing rate on film formation from poly(vinyl acetate) latex particles
(Taylor & Francis Ltd, 2008)
The photon transmission technique was used to monitor the time and temperature evolution of film formation from poly(vinyl acetate) (PVAc) latex particles. The latex films were prepared below the glass transition temperature ...
Optically stimulated luminescence to date coastel dunes and a possible tsunami layer on the Kavak Delta (Saros Gulf, NW Turkey)
(Scientific Technical Research Council Turkey-Tubitak, 2009-01-21)
Optically stimulated luminescence (OSL) dating was used to determine the timing of initial dune formation and reconstruct the evolution of coastal dunes that developed on the Kavak Delta, Saros Gulf, Turkey. Along a 500-mlong ...
Synergistic effect of the locust bean gum on the thermal phase transitions of kappa-carrageenan gels
(Elsevier Sci Ltd, 2009-03)
Synergism between K-carrageenan and locust bean gum (LBG) was studied using the photon transmission technique. Synergistic effects in these polymeric mixtures strongly affected the physical properties of the gel structure. ...
Luminescence dating of prehistoric site of smintheion (Gulpinar) in NW Turkey
(Univ Agean, Dept Mediterranean Stud, 2010)
This study aims to place the prehistoric settlement of Smintheion in northwestern Turkey in its temporal setting on the basis of the dating of the quartz from pottery and sediments collected from the site employing Optically ...
