Plasticity of parental care under the risk of predation: how much should parents reduce care?
(The Royal Society, 2013-08)
Predation can be an important agent of natural selection shaping parental care behaviours, and can also favour behavioural plasticity. Parent birds often decrease the rate that they visit the nest to provision offspring ...
Processamentos utilizados na transformação de polímeros, que geram valor para a sociedade
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia QuímicaUTFPR, 2021-12-04)
The demand for quality resistant packaging with high aesthetic appeal is a decisive factor for the development of companies since the origin of plastic packaging. With the advancement of technology, different shapes, colors ...
Amylopectin-rich starch plasticized with glycerol for polymer electrolyte application
(ELSEVIER SCIENCE BV, 2010)
This paper describes the preparation and characterization of a solid polymer electrolyte based on amylopectin-rich starch plasticized with glycerol. The samples were characterized through ionic conductivity (sigma) ...
An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes
(European Assoc Structural Dynamics, 2014-01-01)
In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found ...

Cyclic behavior and pore pressure generation in sands with laponite, a super-plastic nanoparticle
(2016)
The paper examines the effect of the presence of small percentages (1-5%) by dry mass of the sand of laponite - a synthetic nanoclay with plasticity index exceeding 1000% - on the cyclic response of sand with relative ...
Plastic ingestion risk is related to the anthropogenic activity and breeding stage in an Antarctic top predator seabird species
(Pergamon-Elsevier Science Ltd, 2020-08)
During the last decades plastic pollution has become a common issue in marine environments. Studies on seabirds have focused on species that ingest plastics mistaken for prey or indirectly through their preferred prey or, ...
Fishing plastics: A high occurrence of marine litter in surf-zone trammel nets of Southern Brazil
(Pergamon-Elsevier Science Ltd, 2021-12)
Plastic is one of the most commonly found residues in the marine environment, which can cause several impacts. This study evaluated the interaction of marine litter with surf-zone trammel nets in Southern Brazil. Fifty ...
Influencia da Carga no Comportamento quanto ao Desgaste de um Aco ABNT-1020 Bifasico Revenido a 450°C
(1995-12-01)
The wear rate of the dual-phase steel ABNT-1020 tempered at 450°C sliding against cemented steel ABNT-1020 in function of load value is investigated in wide load range. The alteration in behavior of this function at ...
