Social and population structure in the ant Cataglyphis emmae. [PDF]

open access: yesPLoS ONE, 2013
Dispersal has consequences not only for individual fitness, but also for population dynamics, population genetics and species distribution. Social Hymenoptera show two contrasting colony reproductive strategies, dependent and independent colony ...

Does sticky blood predict a sticky end? Associations of blood viscosity, haematocrit and fibrinogen with mortality in the West of Scotland [PDF]

open access: yes, 2003
There is increasing evidence that blood viscosity and its major determinants (haematocrit, plasma viscosity and fibrinogen) are associated with an increased risk of incident cardiovascular events; however, their associations with mortality are not ...

Assessment of the suitability of different cassava varieties for gari and fufu flour production in Liberia [PDF]

open access: yes, 2020
Open Access Article; Published online: 15 Feb 2020Different cassava varieties are available in Liberia, but there is little knowledge of their product suitability. Hence, the need to assess the potentials of these varieties to produce gari and fufu flour.

The vanishing viscosity limit for Hamilton-Jacobi equations on Networks [PDF]

open access: yes, 2012
For a Hamilton-Jacobi equation defined on a network, we introduce its vanishing viscosity approximation. The elliptic equation is given on the edges and coupled with Kirchhoff-type conditions at the transition vertices. We prove that there exists exactly

Evaluation of the chemical composition and functional properties of gari from Liberia

open access: yesCroatian Journal of Food Science and Technology, 2019
The regular use of local cassava varieties and the exclusion of the fermentation step in the processing of gari in Liberia may affect the composition and properties of gari, hence the need to evaluate its chemical composition and functional properties ...
