FIRST RESULTS IN THE USE OF BOVINE EAR NOTCH TAG FOR BOVINE VIRAL DIARRHOEA VIRUS DETECTION AND GENETIC ANALYSIS.

First Results in the Use of Bovine Ear Notch Tag for Bovine Viral Diarrhoea Virus Detection and Genetic Analysis.

Infection due to bovine viral diarrhoea virus (BVDV) is endemic in most cattle-producing countries throughout the world.The key elements of a Secretagogue BVDV control programme are biosecurity, elimination of persistently infected animals and surveillance.Bovine viral diarrhoea (BVD) is a notifiable disease in Belgium and an official eradication p

Terrestrialization, miniaturization and rates of diversification in African puddle frogs (Anura: Phrynobatrachidae).

Terrestrialization, the evolution of non-aquatic oviposition, and miniaturization, the evolution of tiny adult body size, are recurring trends in amphibian evolution, but the relationships among the traits that characterize these phenomena are not well understood.Furthermore, these traits have been identified as possible "key innovations" that are

An operational improvement of A-4DEnVar and its application to the estimation of the spatially varying bottom friction coefficients of the M2 constituent in the Bohai and Yellow seas

The analytical four-dimensional ensemble variational (A-4DEnVar) data assimilation scheme inherits the advantages of the conventional four-dimensional variational (4D-Var) data assimilation scheme and removes the adjoint model.However, compatible operational improvements such as the reduction of the computational costs and the localization method s

Assessing operational readiness: Regulatory landscape and compliance in zimbabwe for medical devices and in vitro diagnostic medical devices.

The regulation of medical devices and In Vitro Diagnostic (IVD) medical devices have lagged significantly, especially in low- and middle-income countries.Disparities in regulating medical and IVD medical devices in Africa are below the global average.This may translate to poor access to quality-assured medical and IVD devices, resulting in undesira
