Quantitative Risk Assessment for African Horse Sickness in Live Horses Exported from South Africa

African horse sickness (AHS) is a severe, often fatal, arbovirus infection of horses, transmitted by Culicoides spp. midges. AHS occurs in most of sub-Saharan Africa and is a significant impediment to export of live horses from infected countries, such as South Africa. A stochastic risk model was developed to estimate the probability of exporting an undetected AHS-infected horse through a vecto...

Aedes albopictus in Africa? First records of live specimens in imported tires in Cape Town.

Live larvae of Aedes albopictus have been found entering South Africa in used tire casings imported from Japan on 3 separate occasions. This is the first evidence that this mosquito is entering Africa and underlines the value of mosquito monitoring programs to detect the importations of this important vector. It is suggested that undetected populations of Ae. albopictus may have already become ...

Eat to Live or Live to Eat?

Life in most of the world’s urban societies is increasingly sedentary. People neither toil in the fields nor hunt for food. With little need for mobility, there’s easy access to plenty of food that is loaded with sugar, fat, preservatives, and calories. The so-called ‘‘western diet’’ has brought with it a host of metabolic problems that we have probably never encountered in our evolutionary his...

A Versioning Approach to VM Live Migration

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...
