Quaternary Ammonium “Tannate” for Antifouling Coatings
(American Chemical Society, 2012-12)
The undesirable accumulation of a wide variety of marine organisms (biofouling) on ship hulls can lead to significantly increased costs, principally by increased fuel consumption to maintain cruising speed. Generally, these ...
Evaluation of eco-friendly anticorrosive pigments for paints in service conditions
(Elsevier Science Sa, 2010-09)
The performance of different replacements for chromates was studied. The anticorrosive properties of seven phosphate-based pigments, a calcium-exchange silica and a ferrite were assessed by electrochemical techniques and ...
The anti-corrosion performance of water-borne paints in long term tests
(Elsevier, 2017-08)
One of the most inexpensive and effective method to protect steel against corrosion is paints containing active pigments. The traditional way to test these coatings performance is by accelerated tests (exposition to salt ...
Sports in natural environment, sports in urban environment: An fmri study about stress and attention/awareness
This study aimed to explore, on one side, the differences between a group of athletes exercising outdoor (OG) and another group exercising indoor (IG) in stress and awareness, and, on the other side, between-group differences ...
Photosynthetic performance of Chlorella vulgaris R117 mass culture is moderated by diurnal oxygen gradients in an outdoor thin layer cascade
(Elsevier, 2021-04)
Dissolved oxygen concentration is a critical point for microalgae in large scale cultivation systems. Highly productive cultures inevitably generate a build-up of oxygen gradients along the reactor which can affect ...
Diluir los límites: centro educativo en el distrito de Ate Vitarte
(Universidad de San Martín de Porres, 2013)
Explora a través de un proyecto arquitectónico la continuidad del espacio interior y exterior, promoviendo un diálogo entre el entorno y el espacio escolar, entendido como “patio abierto”. La problemática explorada es la ...
Thermal Energy Replacement Potential in a Slaughter Plant From Rumen Pellets
(Cartagena de IndiasCampus Tecnológico, 2020-11-19)
In this work, steam generation was studied using natural gas or rumen as energy sources in a slaughter plant that sacrifices 7500 cattle per month, with consumption 0.5749 kg/s of saturated steam at 624 kPa. For a slaughtered ...
