Interrelations of Behavioral, Emotional, and Cognitive School Engagement in H…
School engagement, or the extent to which students are involved in, attached and committed to the academic and social activities in school, plays a prominent role in preventing academic failure, promoting competence, and influencing a wide range of adolescent outcomes. Although the multidimensional nature of school engagement is wellrecognized, how the three purported parts of the construct wo…

Chemical Structures Present in Biofuel Obtained from Lignin
Technical lignins from various sources can be converted into bio-oil with a low O/C ratio by pyrolysis in the presence of formic acid and an alcohol. By application of different analytical techniques, such as Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), electrospray ionization mass spectrometry (ESI-MS), and size-exclusion chromatography (SEC), it has been …

Catalytic Carbon Dioxide Reforming of Methane to Synthesis Gas over Activated…
The catalytic activity and kinetic behavior of catalytic reforming of methane with carbon dioxide over activated carbon were investigated as a function of reaction temperature, gas hourly space velocity (GHSV), and partial pressures of CH4 and CO2. The CH4 and CO2 conversions were greatly influenced by the reaction temperature in the range of 850-1050 °C. The apparent activation energies for C…

The Effects of Amlodipine and S(-)-Amlodipine on Vascular Endothelial Functio…
Background Amlodipine has been shown to improve vascular endothelial function in hypertensive patients, but whether S(-)-amlodipine has a similar effect remains controversial. This study compared the effects of amlodipine and S(-)-amlodipine on vascular endothelial function in hypertensive patients and investigated relevant mechanisms of action in cell culture. Methods Twenty-four patient…
