Endothelial Cell Colonization And Angiogenic Potential Of Combined Nano- And Micro-Fibrous Scaffolds For Bone Tissue Engineering
(Elsevier Sci Ltd, 2008)
Presently the majority of tissue engineering approaches aimed at regenerating bone relies only on post-implantation vascularization. Strategies that include seeding endothelial cells (ECs) on biomaterials and promoting ...
In Vivo And In Vitro Effects Of A Hif-1 Alpha Inhibitor, Rx-0047
(Wiley, 2008)
HIF-1 alpha plays a major role in activating gene transcription and is important for maintaining homeostasis under hypoxic conditions. Since tumors are often in a hypoxic state, HIF-1 alpha is a potential target for the ...
Ict Integration Processes In Turkish Schools: Using Activity Theory To Study Issues And Contradictions
(Australasian Soc Computers Learning Tertiary Education-Ascilite, 2008)
This study used activity theory to examine complex pedagogical, social, and technological issues in ICT integration process at the classroom level. We identified and analysed the contradictions within the activity system ...
A Study of Student's Perceptions in A Blended Learning Environment Based on Different Learning Styles
(Ieee Computer Soc, Learning Technology Task Force, 2008)
The rapid growth in the use of learning technologies, particularly the use of the web based technologies and communications have offered educators with many more opportunities to investigate the most suitable learning ...
A Structural Equation Model For Ict Usage in Higher Education
(Natl Taiwan Normal Univ, Taiwan, 2008)
This study focuses on Information and Communication Technologies (ICT) usage, which is the indicator of diffusion. A model composed of the variables which can explain ICT usage in Turkish higher education is established ...
Long-Time Behaviour of Wave Equations with Nonlinear Interior Damping
(Amer Inst Mathematical Sciences-Aims, 2008)
We prove the existence of attractors for higher dimensional wave equations with nonlinear interior damping which grows faster than polynomials at infinity.
Temperature and Electric Field Dependences of the Mobility of Electrons in Vertical Transport in Gaas/Ga(1-Y)Al(Y)As Barrier Structures Containing Quantum Wells
(Versita, 2008)
The mobility of electrons in vertical transport in GaAs/Ga(1-y)Al(y)As barrier structures was investigated using geometric magnetoresistance measurements in the dark. The samples studied had Ga(1-y)Al(y)As (0 <= y <= 0:26) ...
Regional Tec Mapping with Random Field Priors and Kriging
(Amer Geophysical Union, 2008)
Total Electron Content ( TEC) is an important parameter in monitoring ionospheric variability. In a given region, TEC can be obtained only by interpolation of measurements due to sparsity of the useful data. The lack of a ...
