Abstract The coronavirus disease 2019 (COVID-19) pandemic has once again brought borders to the center of attention, as journalists, authorities, and scholars have grappled with pandemic. outbreak, which began in late early 2020 caused tremendous personal, economic, social upheaval. As many states decided pursue national interests close their prevent spread virus, this decision had major conseq...

Left ventricular status, reflected in ejection fraction or end systolic volume, is a powerful prognostic indicator in heart disease. Quantitative analysis of these and other parameters from ventriculograms is infrequently performed due to the expense of manual segmentation. We present a method for semi-automatic segmentation of ventriculograms based on a two-stage boosted decision-tree pixel cl...

Australia is a significant livestock producer and a major exporter of livestock, livestock products and livestock genetic material. An outbreak of foot and mouth disease (FMD) would have severe economic consequences on the economy. A recent study found that in an outbreak lasting six months, real gross domestic product in Australia would fall by an estimated 0.6% (AUS$3.5 billion), employment b...

Sporidesmin is the mycotoxin that causes facial eczema disease (FE) in New Zealand (NZ) livestock. In an artificial sporidesmin dosing test, the introduced Finnish Landrace sheep breed was found to be significantly more tolerant to FE than the introduced Texel breed. This finding enables cross-breeding strategies to improve disease tolerance. Combining published data with the current study, a t...

Abstract Background Border closure is one of the policy changes implemented to mitigate against coronavirus disease 2019 (COVID-19). We evaluated effect border on incidence rate COVID-19 across nine African countries. Methods An interrupted time series analysis was used assess rates in Egypt, Tunisia, Democratic Republic Congo (DRC), Ethiopia, Kenya, Ghana, Nigeria, Senegal and South Africa (SA...

Background Left ventricular (LV) parameters may vary with aging, but concomitant disease can obscure relationships between age and LV size, mass and function. CMR provides reproducible measures of LV volumes, mass, and ejection fraction (EF), but manual analyses are time consuming. Automated border detection (ABD) methods may decrease analytical burden. We sought to examine the effect of greate...

Within weeks of the February 2001 outbreak of foot-and-mouth disease in the UK, a number of measures were introduced at the border to reduce the risk of introduction of the disease into New Zealand. This paper examines the process that led to these decisions, and compares it to the decision-making process implied under the WTO framework. In particular, difficulties in determining the acceptable...

A survey conducted near a dam-site on the Paraguay-Argentine border showed the area to be highly endemic for Chagas’ disease. It also showed that new housing unsuited to the disease vector’s prol$eration did not eliminate the prob/em, indicating a strong need for health education capable of guiding people away from traditional behavior patterm tending to encourage the vector and cause infection.
