• #### Behavioral evidence of hunting and foraging techniques by a top predator suggests the importance of scavenging for preadults ﻿

(Wiley Online Library, 2017)
Scavenging may be a regular feeding behavior for some facultative raptor species oc-cupying low quality habitats and/or with little experience in hunting techniques. However, its importance has been largely ...
• #### Behaviour of the current in a membrane-covered disc microelectrode under steady-state conditions ﻿

(The Royal Society of Chemistry, 1996)
The inlaid disc electrode covered with a membrane can be modelled as a system with axial symmetry containing several parallel layers with different permeabilities. A recent solution of the steady state under diffusion ...
• #### Bi-magic and other generalizations of super edge-magic labelings ﻿

(Cambridge University Press, 2011)
In this paper, we use the product ⊗h in order to study super edge-magic labelings, bi-magic labelings and optimal k-equitable labelings. We establish, with the help of the product ⊗h, new relations between super edge-magic ...
• #### Bi-Objective Optimization Model Based on Profit and CO2 Emissions for Pig Deliveries to the Abattoir ﻿

(MDPI, 2018)
This paper presents a bi-objective model for optimizing pig deliveries to the abattoir accounting for total revenue and CO2 emissions. Fattening farms house the most important stage in pig production, and operations on ...
• #### Can wild ungulate carcasses provide enough biomass to maintain avian scavenger populations? An empirical assessment using a bio-inspired computational model ﻿

(Public Library of Science (PLoS), 2011)
Background: The reduction in the amount of food available for European avian scavengers as a consequence of restrictive public health policies is a concern for managers and conservationists. Since 2002, the application of ...
• #### Carrion ecology modelling for vulture conservation : are vulture restaurants needed to sustain the densest breeding population of the African white-backed vulture? ﻿

(Wiley, 2015)
As obligate scavengers, vultures are entirely dependent on carrion resources. In this study we model the carrion ecology of an ecosystem in Swaziland which is home to the densest breeding population of the African White-backed ...
• #### Center conditions and limits cycles for bilienard systems ﻿

(Texas State University, 2017)
In this article we study the center problem for polynomial BiLiénard systems of degree n. Computing the focal values and using Gröbner bases we end the center conditions for such systems for n = 6. We also establish ...
• #### Center conditions for generalized polynomial Kukles systems ﻿

(American Institute of Mathematical Sciences, 2017)
• #### Centers for the Kukles homogeneous systems with even degree ﻿

(Shanghai Normal University & Wilmington Scientific Publisher, 2017)
For the polynomial differential system x˙=−y, y˙=x+Qn(x,y), where Qn(x,y) is a homogeneous polynomial of degree n there are the following two conjectures done in 1999. (1) Is it true that the previous system for n≥2 has a ...
• #### Centers for the Kukles homogeneous systems with odd degree ﻿

(London Mathematical Society, 2015)
For the polynomial differential system x˙ = −y, y˙ = x+Qn(x; y), where Qn(x; y) is a homogeneous polynomial of degree n there are the following two conjectures done in 1999. (1) Is it true that the previous system for ...
