A photon transmission study for film formation from poly(vinyl acetate) latex particles with different molecular weights
(John Wiley & Sons Inc, 2007-10-15)
The photon transmission technique was used to monitor the temperature evolution of film formation from poly(vinyl acetate) (PVAc) latex particles with two different molecular weights. Two sets of latex films were prepared ...

Laplacian eigenvectors of graphs: Perron-Frobenius and Faber-Krahn type theorems
(Springer Verlag, 2007)
Eigenvectors of graph Laplacians have not, to date, been the subject of expository articles and thus they may seem a surprising topic for a book. The authors propose two motivations for this new LNM volume: (1) There are ...
Comparison of evolutionary techniques for Value-at-Risk calculation
(Springer-Verlag Berlin, 2007)
The Value-at-Risk (VaR) approach has been used for measuring and controlling the market risks in financial institutions. Studies show that the t-distribution is more suited to representing the financial asset returns in ...
Estimation of microstretch elastic moduli by the use of vibrational data
(Springer, 2007)
In the present work, a nonlinear wave theory is used for the estimation of the material properties of a "microstretch" medium. For this purpose a thin plate is considered and triplicate Chebyshev polynomial series are used ...
Studying on the small molecule diffusion into hydrogels: a fluorescence study
(Amer Inst Physics, 2007)
In situ steady state fluorescence experiments (SSF) were reported during the diffusion of water molecules into PAAm in gels at various temperatures. The fluorescence emission intensities, Ip increased continuously as water ...
On complex solutions of the eikonal equation
(IEEE, 2007)
In this paper a new approach of complex rays in an inhomogeneous medium is presented. Complex rays are complex solutions of the eikonal equation, the main equation of the geometical optics. It is shown that solving the ...
Mixed-method validation of pedagogical concepts for an intercultural online learning environment: a case study
(Assoc Computing Machinery, 2007)
The rise of social software poses the challenges to the design and evaluation of a pedagogically sound online learning environment (OLE). Our OLE addresses these challenges by the integration of three pedagogical concepts ...
Small molecule diffusion into swelling Iota-Carrageenan gels: A fluorescence study
(Taylor & Francis Group, 2007-04)
Small molecule diffusion into Iota-Carrageenan gel was studied by using steady-state fluorescence (SSF) technique. Pyranine, dissolved in water was used as fluorescence probe. Fluorescence emission intensity, I-p, and ...
Universality of sol-gel phase transition of kappa-carrageenan in various salts: a steady state fluorescence study
(Taylor & Francis Ltd, 2007-08)
Thermal phase transitions of kappa-carrageenan in NaCl, KCl and CaCl2 solutions were studied using steady state fluorescence (SSF) technique. Pyranine was introduced as a fluorescence probe for studying sol-gel phase ...
