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 ...
Weakly non-linear waves in a fluid-filled elastic tube with variable prestretch
(Pergamon-Elsevier Science Ltd, 2008-11)
In the present work, by utilizing the non-linear equations of motion of an incompressible, isotropic thin elastic tube subjected to a variable prestretch both in the axial and the radial directions and the approximate ...
Thermochemical conversion of bean pods to carbon materials and gas
(Freund Publishing House Ltd, 2008)
The preparation of activated carbons from bean pods by chemical (K(2)CO(3)) and physical (water vapor) activation was investigated. The carbon prepared by chemical activation presented more developed porous structure than ...
Relocating sensor nodes to maximize cumulative connected coverage in wireless sensor networks
(Molecular Diversity Preservation Int, 2008-04)
In order to extend the availability of the wireless sensor network and to extract maximum possible information from the surveillance area, proper usage of the power capacity of the sensor nodes is important. Our work ...
Study of drying of kappa-carrageenan gel at various temperatures using a fluorescence technique
(Taylor & Francis Inc, 2008-01)
The steady-state fluorescence technique was used to study drying of kappa-carrageenan gel at various temperatures. Pyranine was doped as a fluorescence probe, and scattered light, I-sc, and fluorescence intensities, I, ...
Weakly nonlinear waves in a fluid with variable viscosity contained in a prestressed thin elastic tube
(Pergamon-Elsevier Science Ltd, 2008-04)
In this work, treating the artery as a prestressed thin elastic tube and the blood as an incompressible Newtonian fluid with variable viscosity which vanishes on the boundary of the tube, the propagation of nonlinear waves ...
Nonlinear waves in an elastic tube with variable prestretch filled with a fluid of variable viscosity
(Pergamon-Elsevier Science Ltd, 2008-10)
In the present work, by employing the reductive perturbation method to the nonlinear equations of an incompressible, prestressed, homogeneous and isotropic thin elastic tube and to the exact equations of an incompressible ...
Graphs with given degree sequence and maximal spectral radius
(Electronic Journal of Combinatorics, 2008-09-15)
We describe the structure of those graphs that have largest spectral radius in the class of all connected graphs with a given degree sequence. We show that in such a graph the degree sequence is non-increasing with respect ...
Luminescence ages of feldspar contaminated quartz from fluvial terrace sediments
(Wind-J Wojewoda Publ Co, 2008-01-01)
This study focuses on obtaining luminescence ages in feldspar contaminated quartz from well-developed fluvial terraces of the Yesilirmak (Iris) river located inside the eastern North Anatolian Fault Shear Zone (NAFZ). We ...
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 ...
