CFD modelling of drop formation in a liquid-liquid system

The formation of an oil drop from a single capillary in a continuous phase flowing perpendicular to the capillary opening has been studied numerically. The shear stress at the interface of the forming drop, the angular velocity inside the drop and the pressure field around the drop have been determined in a cross section of the drop formation area. The results show a maximum pressure in the contin

Comparison of two methods for evaluating image quality of chest radiographs

A set of 15 analog chest images was digitized with a high performance scanner and manipulated in terms of noise and resolution to yield three sets of images; the original plus two with different noise and resolution properties. These sets were evaluated with Visual Grading Analysis (VGA) where the observer rates the visibility of certain normal anatomical structures (as described by the European Q

Rehabiliteringspedagogik för arbete med långtidssjukskrivna i grupp

REHABILITERINGSPEDAGOGIK är en bok om hur författaren har letat sig fram till ett sätt att återvinna långtidssjukskrivna människor till livet. Det är också en bok om hur långtidssjukskrivna lär sig nya sätt att tänka, känna och bete sig med sikte på förbättrad hälsa och funktion. Boken bygger på författarens mångåriga erfarenhet av arbete med människor som har långvarig värk och smärta, först som

Luftföroreningar vid svetsning

PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalis

A preliminary phylogeographic study of Flavopunctelia and Punctelia inferred from rDNA ITS-sequences

A preliminary phylogeny of the genera Flavopunctelia and Punctelia is presented. Genus and species delimitations have been investigated using ITS rDNA-sequencing of populations from different continents. Current genus delimitations of Flavopunctelia, Punctelia and Parmelia are confirmed and the species status of recently resurrected Punctelia ulophylla is confirmed. The status of three cryptic spe

BI Views: Connection, Immersion, and Fusion Through the Lens of Emergence

In the debate on the core of Information System (IS), El Sawy identified three faces of IS views: connection, immersion, and fusion. However, no research has further elaborated these concepts. For this task, we adopted the characteristics of the old concept of “emergence” to better describe and explain the shifts in IS from connection to immersion and finally towards fusion. A police organization

Development as a Gift

Discusses the export of values and capacity building in development aid using the anthropological concept of 'the gift'
