First note on marine-like cementation of Late Holocene beachrock, Iznik Lake (Turkey)
(Versita, 2012-03)
Micro-fabric characteristics and optically stimulated luminescence (OSL) dating results are presented to discuss the controlling agents and timing of beachrock cementation on the fresh-water Iznik Lake shoreline. The ...
Investigation of the OSL signal from very deep traps in natural quartz
(Univ Agean, Dept Mediterranean Stud, 2010)
It has been recently reported by several studies that a thermally transferred optically stimulated luminescence (TT-OSL) signal from quartz grains can be used to extend the dating range for quartz samples. The TT-OSL signals ...
Preliminary TL and OSL investigations of obsidian samples
(Univ Agean, Dept Mediterranean Stud, 2010)
Obsidian is a volcaniclastic mineral extremely hard to break, which was used in prehistoric Greece (and elsewhere in the World), in order to provide tools, weapons, knives and arrowheads. The present work aims to characterize ...
Preliminary results towards the equivalence of transformed continuous-wave Optically Stimulated Luminescence (CW-OSL) and linearly-modulated (LM-OSL) signals in quartz
(Versita, 2011-09)
The present paper presents a comparative experimental study of two commonly measured Optically Stimulated Luminescence (OSL) signals in quartz. The experimental study measures both the continuous wave OSL (CW-OSL) and the ...
Evolutionary route to diploidy and sex
(National Academy of Sciences, 2001-11-20)
By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid ...
The statistics of energy states of a Hookean model for proteins
(TÜBİTAK, 2000)
A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean springs connecting pairs of hydrophobia residues, reproduces the energy probability distribution of real proteins over ...
