Artikkelen handler om den internasjonale dimensjonen ved ansvaret for å beskytte befolkninger mot forbrytelser av massivt omfang: folkemord, forbrytelser mot menneskeheten, krigsforbrytelser og fordrivelse på etnisk grunnlag. Denne dimensjonen forvaltes av FNs sikkerhetsråd og aktiveres når det nasjonale ansvaret, som er det primære, ikke fungerer. Beskyttelsesansvaret (R2P) ble vedtatt ved konsensus ...

Rabies hos flaggermus er utbredt over store deler av verden og er også registrert i mange områder i Europa. Fjorten av Europas rundt 40 arter er rapportert å ha vært eksponert for rabiesvirus enten ved påvisning av viruset eller ved funn av antistoffer i blod. Rabiesvirus som forekommer hos flaggermus i Europa kalles European Bat Lyssavirus (EBLV) og finnes i to varianter, EBLV1 og EBLV2 (også kalt ...

Jean Toomer’s seldom-discussed long poem “The Blue Meridian,” which he drafted over a long period beginning in the early 1920s, proposes an amalgamation of race and national belonging in the new type of the “American.” Seeing himself as a precursor to this new hybrid, Toomer often polemicized against the limiting logic of race. In proposing such an understanding of race in relation to nation, Toomer ...

BACKGROUND: The major risk factors for atherosclerotic cardiovascular disease differ by race or ethnicity but have largely been defined using populations of European ancestry. Despite the rising prevalence of cardiovascular disease in Africa there are few related data from African populations. Therefore, we compared the association of established cardiovascular risk factors with carotid-intima ...

Abstract Echocardiography plays a critical role in the assessment of cardiac disease. Important differences in echocardiographically derived cardiac chamber dimensions have been previously highlighted in different population groups in adult studies, but this has not been systematically studied in children, whose body size changes throughout childhood. The aim of this study was to review the ...

Radar observations can be used to obtain accurate orbital elements for near-Earth objects (NEOs) as a result of the very accurate range and range rate measureables. These observations allow the prediction of NEO orbits further into the future and also provide more information about the properties of the NEO population. This study evaluates the observability of NEOs with the EISCAT 3D 233 MHz 5 MW ...

Incoherent scatter radar observations of ionospheric plasmas rely on echoes from electron density fluctuations with properties governed by the dispersion relations for ion acoustic and Langmuir waves. Radar observations of echoes associated with Langmuir waves (plasma lines) from thermal plasma are weak, and only a few near‐thermal level measurements have been reported. Plasma line echoes are typically ...

Dust plasma phenomena occur in the Earth ionosphere in particular in the meteor ablation zone at altitudes ~50-95 km and above where radar meteors form. Radar also detect coherent polar mesospheric radar echoes (PME), i.e. radar echoes that are caused by spatial variations in the plasma refractive index at around 80 to 90 km altitude in the Earth’s mesosphere. During summer, PM(S)E form in the ...

Incoherent scatter radar measurements are an important source for studies of ionospheric plasma parameters. Data from the EISCAT Svalbard radar (ESR), which covers the polar cap and cusp, and from the EISCAT Tromsø radars, which covers the auroral zone, can be used to obtain information about the electron density, electron- and ion temperature, and line-of-sight plasma velocity. As the ESR started ...

Radio waves provide a useful diagnostic tool to investigate the properties of the ionosphere because the ionosphere affects the transmission and properties of high frequency (HF) electromagnetic waves. We have conducted a transionospheric HF-propagation research campaign with a nanosatellite on a low-Earth polar orbit and the EISCAT HF transmitter facility in Tromsø, Norway, in December 2020. In ...
