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 ... -
Film formation from nano-sized polystrene latex covered with various TiO2 layers
(Wiley, 2006-12)Steady-state fluorescence technique was used for studying film formation from TiO2 covered nano-sized polystyrene latex particles. The composite films were prepared from pyrene (P)-labeled PS particles by covering them ... -
Film formation from nano-sized polystyrene latex particles
(John Wiley & Sons Ltd, 2005-05)This work reports on the steady state fluorescence (SSF) technique for studying film formation from surfactant-free, nano-sized polystyrene (PS) latex particles prepared via emulsion polymerization. The latex films were ... -
Film formation from PS latex doped PNIPAM hydrogels at various heating and cooling rates
(VSP BV, Brill Academic Publishers, 2008-05-01)Film formation from polystrene (PS) latex doped poly(N-isopropylacrylamide) (PNIPAM) hydrogels was studied by using photon transmission technique. The transmitted light intensity, It, was monitored during film formation ... -
Film formation from pure and mixed latices; transient fluorescence study
(Academic Press Inc Elsevier Science, 2005-11-15)A fast transient fluorescence technique was used to study latex film formation induced by organic solvent vapor. Mixtures of pyrene (P)- and naphthalene (N)-labeled and/or pure naphthalene-labeled latex films were prepared ... -

(Springer New York, 2005-07)This study reports a steady-state fluorescence (SSF) technique for studying film formation from surractant-free polystyrene (PS) latex and Na-montmorillonite (SNaM) composites. The composite films were prepared from pyrene ... -
The firing temperature of pottery from ancient Mesopotamia, Turkey, using luminescence methods: a case study for different grain-size fractions
(Wiley-Blackwell, 2014-10)The assessment of the firing temperature of a prehistoric pottery sample collected from ancient Mesopotamia, Turkey was studied using luminescence techniques. The methods for this estimation involved the observation of the ... -
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 ... -
Fluctuation theory of the liquid-glass transition
(Trans Tech Publications Ltd, 2004)The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ... -
