Initial evidence to validate an instructional design-derived evaluation scale in higher education programs
(Springer, 2016-02-26)
Instructional design has been a key strategy in ensuring the quality of higher education; therefore, it is essential to evaluate its effects on learning processes through the use of tools that comply with defined technical ...
Biopulp from pineapple leaf fiber produced by colonization with two white-rot fungi: Trametes versicolor and Pleurotus ostreatus
(BioResources, 2016)
Trametes versicolor and Pleurotus ostreatus were used for the biopulping from pineapple leaf fiber (PALF). PALF substrate was subjected to T. versicolor for 2 to 6 weeks and to P. ostreatus for 4 to 8 weeks. The yields, ...
Synthesis, properties, and two-dimensional adsorption characteristics of 5-amino[6]hexahelicene
(Willy, 2016)
A convergent synthesis of racemic 5-amino[6]hexahelicene
is described. Cross-coupling reactions are used to
assemble a pentacyclic framework, and a metal-catalyzed
ring-closure comprises the final step. The enantiomers ...
