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 ...

With the ligands 4-phenyl-1-(furan-2-carbaldehyde)thiosemicarbazone, HTSC1, (1), 4-phenyl-1- (5 -phenyl-furan-2-carbaldehyde)thiosemicarbazone, HTSC2 (2), o-methoxy-benzaldehydethiosemicarbazone, HTSC3 (3), and ...
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 ...
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 ...
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 ...
Microstructural stability, microhardness and oxidation behaviour of in situ reinforced Ti–8.5Al–1B–1Si (wt%)
(Kluwer Academic Publishers, 1998)
Microstructural stability, microhardness and oxidation behaviour of an in situ reinforced Ti–8.5Al–1B–1Si (wt%) alloy was examined in both air and argon environments. When exposed for up to 5760 min at temperatures below ...
Comparison between solar distillers with and without solar concentrator
(Allerton Press, Inc., 2016)
In order to desalinate sea water by only solar energy using they were designed and built three distillers in which experimental measurements were taken to calculate production, performance and cost. Distillers by solar ...
Preliminary overview and evaluation of a stepped solar distiller with internal reflective walls and borosilicate vacuum tubes
(Elsevier BV, 2017)
The present study demonstrates that the current use of stepped solar distillers can be enhanced to increase seawater desalination. To this end, we designed a stepped solar still with internal reflective walls and attached ...
Synthesis and Characterization of New Palladium(II) Thiosemicarbazone Complexes and Their Cytotoxic Activity against Various Human Tumor Cell Lines

The palladium(II) bis-chelate complexes of the type [Pd(TSC1-5)2] (6–10), with their corresponding ligands 4-phenyl-1-(acetone)-thiosemicarbazone, HTSC1 (1), 4-phenyl-1-(2'-chloro-benzaldehyde)-thiosemicarbazone, HTSC2 ...
Design and construction of a fresnel linear distiller
(Allerton Press, Inc., 2014)
It was designed a Fresnel linear distiller based on optical calculations obtained from taking into account Lima's latitude value, Earth inclination angle and heat absorber cavity's dimensions. The 5.6 m^sup 2^ reflective ...
