Intelligence in Peru: Students' results in Raven and its relationship to SES.
Several studies have tried to estimate the average cognitive ability level in Peru. The results oscillated between IQ 90 (Lynn & Vanhanen, 2002) and 85 (Lynn & Vanhanen, 2006, 2012). Moreover, regional studies conducted ...
Nanostructured Screen-Printed Electrodes Modified with Self-Assembled Monolayers for Determination of Metronidazole in Different Matrices
(Sociedade Brasileira de Quimica, 2014)
This paper describes the development of a sensor for the determination of metronidazole using a simple method involving the creation of nanoporous structures on gold electrodes followed by modification with self-assembled ...
(Cambridge University Press, 2017)
Astrobiology is a discipline that is expanding its field of investigation not only in the natural sciences, but also in the social sciences. It is for this reason that the ethical aspects are progressively emphasized leading ...
A Case Study: Data Mining Applied to Student Enrollment
(Educational Data Mining, 2010)
One of the main problems faced by university students is deciding the right learning path based on available information such as courses, schedules and professors. In this context, this paper presents a recommender system ...
Autonomous and controlled regulation of performance-approach goals: Their relations to perfectionism and educational outcomes
The present research uses self-determination theory to examine whether autonomous and controlled regulation of performance-approach (PAp) goals would differentially predict educational outcomes and add to the variance ...
Desalination using a parabolic-trough concentrator
(Allerton Press Inc., 2012)
There are presented desalination results by using a parabolic-trough concentrator (PTC) device of 5.5 m2, 0.7 m of line focal distance and aligned in the East—West direction. The length of the PTC is 2.5 m and its rectangular ...
Database methodology for therapy evaluation in auditory schizophrenia disorder based on continuity evolution of symptoms
In the context of a medication or therapy course, an intriguing question may arise after a few therapies: Should the treatment or therapy be continued? Even after several instances of therapy, there are not clear measures ...
Influence of Pyrolytic Seeds on ZnO Nanorod Growth Onto Rigid Substrates for Photocatalytic Abatement of Escherichia coli in water
(IWA Publishing, 2014)
ZnO nanorods (ZnO NRs) were grown on ZnO seeded fluorine doped tin oxide (FTO) substrates at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO seeds were deposited on the FTO substrate ...
Synthesis and Characterization of New Palladium(II) Thiosemicarbazone Complexes and Their Cytotoxic Activity against Various Human Tumor Cell Lines
