Changes in digestive enzymes activities during the initial ontogeny of wolf cichlid, Parachromis dovii (Perciformes: Cichlidae)
(Sociedade Brasileira de Ictiologia, 2019)
Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated ...
Biomass allocation and gas exchange are affected by light conditions in endangered Cedrela salvadorensis (Meliaceae) seedlings
(Universidad de Costa Rica, 2016)
The determination of favorable light habitat conditions per species and life stage is transcendental,
for both ex situ and in situ conservation strategies of endangered forest tree species, and for their utilization as ...
Infragravity wave energy partitioning in the surf zone in response to wind-sea and swell forcing
(MDPI AG, 2019)
An alongshore array of pressure sensors and a cross-shore array of current velocity and
pressure sensors were deployed on a barred beach in southwestern Australia to estimate the relative
response of edge waves and leaky ...

Cloning, purification and characterization of nigrelysin, a novel actinoporin from the sea anemone Anthopleura nigrescens
(Elsevier B.V., 2019)
Actinoporins constitute a unique class of pore-forming toxins found in sea anemones that being secreted
as soluble monomers are able to bind and permeabilize membranes leading to cell death. The interest in
these proteins ...
A mixed virtual element method for a pseudostress-based formulation of linear elasticity
(Elsevier B.V., 2019)
In this paper we introduce and analyze a mixed virtual element method (mixed-VEM)
for a pseudostress-displacement formulation of the linear elasticity problem with non homogeneous Dirichlet boundary conditions. We follow ...
