Numerical study of heat transfer, flow fields, turbulent length scales, and anisotropy in corrugated heat exchanger channels

In this study, we report on large eddy simulation (LES) of convectively dominated heat transfer in a corrugated heat exchanger channel using the computational fluid dynamics toolbox, OpenFOAM. A chevron pattern domain with 63 contact points is used to represent the conditions in a real plate heat exchanger (PHE). The unsteady nature of the flow is elucidated using visualization techniques based on

Morphological and ultrastructural alterations of zebrafish (Danio rerio) spermatozoa after motility activation

Spermatozoa motility in freshwater and marine fish is mainly controlled by the difference in osmotic pressure. Specifically, zebrafish (Danio rerio) spermatozoa undergo hypoosmotic shock due to the decrease in extracellular potassium, which leads to membrane hyperpolarization and activation of flagellar motility. Previous studies have concluded that motility activation has a negative effect on the

Framtidens historia

Framtiden är gammal. Mötet med morgondagen har sannolikt upptagit människors medvetande från allra äldsta tid. Här presenteras hela framtidens historia, från babyloniernas stjärntydningar till våra dagars hamstring och prepping. I huvudsak behandlas människors föreställningar, visioner, önskningar och rädslor inför framtiden i olika kontexter och under olika historiska epoker.

Science, Language, and Reform in Victorian Poetry : Political Dialects

Barrow’s timely book is the first to examine the link between Victorian poetry, the study of language, and political reform. Focusing on a range of literary, scientific, and political texts, Barrow demonstrates that nineteenth-century debates about language played a key role in shaping emergent ideas about popular sovereignty. While Victorian scientists studied the origins of speech, the history o

Illicit Trafficking of Cultural Properties in Arab States

The present edited research aims to capture a bird’s-eye view of the phenomenon of illicit trafficking of cultural properties and to serve as a reference point for governments, enforcement agencies, international organizations, stakeholders, and civil societies. The targeted geographic region is the Arab World, the countries in the Middle East, Arabic Gulf, Horn of Africa and North Africa. There i

Employment and Structural Change : Economic Integration of Immigrants in the Swedish and Malmo Labour Markets 1970-1990

Sweden developed during the first two decades of the post-war period into one of the wealthiest countries in the world. This change in the wealth of the country was accompanied by immigration on a previously unknown scale. Sweden’s remarkable economic growth has been facilitated by this immigrant flow, which consisted almost entirely of European labour migrants during the period up to the early 19

DNA promoter hypermethylation of melanocyte lineage genes determines melanoma phenotype

Cellular stress contributes to the capacity of melanoma cells to undergo phenotype switching into highly migratory and drug tolerant dedifferentiated states. Such dedifferentiated melanoma cell states are marked by loss of melanocyte specific gene expression and increase of mesenchymal markers. Two crucial transcription factors, MITF and SOX10, important in melanoma development and progression hav

New paths of understanding electricity use behaviour in energy-efficient buildings

Background and objectivesEnergy use behaviour is a complex issue and multiple perspectives are needed to fully understand it. It is difficult to define the most effective strategies or behaviours that reduce energy use in residential environment (Casado et al., 2015) despite efforts put on energy-efficient design and technologies. This study focuses on cognitive processes on electricity use behavi

Vores nærlæsning af pjecen tager udgangspunkt i begrebet „socio-tekniske forestillinger“, der søger at forene et blik for teknologiers betydning i moderne samfund med en forståelse af deres indlejring i sociale normer, institutioner og praksisser, saThis article examines the production of futures in the pamphlet Hvis krigen kommer (If War Comes), published by the Prime Minister’s Office and di-stributed to every Danish household in January 1962. In the preceding decades, nuclear science and technology had become central in the imagination of both peaceful and conflict-ridden futures. How to survive a nuclear war – and whether this was even po

Abstract in DanishDen Kolde Krigs ophør resulterede i et opgør om historien: Om magten til at skrive historien og om retten til at definere, hvem der var de gode, og hvem der var de onde. I Danmark har kampen om historien været særlig voldsom. Beskyldninger om nationalpolitisk svigt, moralsk forræderi og historiemisbrug har præget debatten, hvor gamle regnskaber gøres op i aktuelle magtkampe, hvor
