A review of several typical enhanced heat transfer tubes such as corrugated tube, transversally corrugated tube, twisted tube and spiral fluted tube, is carried out. Compared with smooth wall tube, these enhanced tubes have higher heat exchange capacity and better anti - fouling ability. Besides, the heat transfer efficiency can be promoted to a higher level if the objects that can disturb flow ar

A novel atmospheric pressure non-thermal plasma, i.e., rotating gliding arc (RGA), is developed to upgrade coal bed methane (CBM) into hydrogen and carbon aerosol simultaneously. CH4 is used as a CBM surrogate. In present work, the V-I characteristics of RGA discharge in CH4 conversion are monitored with different gases (N2, Ar and CO2) as carrier gas, while the active species (such as OH, CH, CN,

Scholarship on branding has made important contributions in terms of the value-creating function of branding. However, previous literature has overemphasized the creation of value for organizations at the expense of an understanding of the destructive side of branding for organizations and society. Drawing on the work of Boltanski and Thevénot, we theorize value as different in separate ‘worlds of

De protestantiska kyrkorna liksom kyrkorna i Östeuropa uppmuntrar präster att ingå äktenskap. Att den katolska kyrkan håller fast vid celibatet har en disciplinär funktion. I artikeln ges historiska perspektiv på prästcelibatet, kritiken mot detta och motiven för dess bibehållande.

Det arkeologiska perspektivets tidsdjup ger kunskap om förändringar av människans livsval. De arkeologiska föremålen betraktas som ett slags tidsmarkörer som materialiserar en tids idéer om formgivning, tillverkning och konsumtion av produkter och hur dessa kan ingå i en föreställningsvärld om tid. Vår egen tids föreställning om tid påverkar ytligt tolkningen av forntida material.

Routine endomyocardial biopsy (EMB) to detect acute cellular rejection (ACR) late (>1 year) after heart transplantation (HT) remains debated. To gain knowledge on late ACR and thereby approach this issue, we studied the incidence, predictors, and outcome of late ACR. 815 late EMBs from 183 patients transplanted 1988-2010 were retrospectively reviewed until June 30, 2012. Only 4.4% of the routine a

Background: There is a need for increased understanding of the pre-diabetic period in individuals with high risk of type 1 diabetes from the general population. Methods: High-risk children (n = 21) positive for multiple islet autoantibodies were identified by autoantibody screening within the All Babies in Southeast Sweden study. The children and their parents were enrolled in a 2-year prospective

A survey of four co-design tools for joint analysis, simulation, and design of computer-based control systems developed within the Swedish ARTES programme is presented. The tools allow simultaneous treatment of the control aspects and the computing and communication aspects of the control problems. The tools are Jitterbug and TrueTime developed at the Department of Automatic Control LTH, Lund Univ

The paper presents the control server, a real-time scheduling mechanism tailored to control and signal processing applications. A control server creates the abstraction of a control task with a specified period and a fixed input-output latency shorter than the period. Individual tasks can be combined into more complex components without loss of their individual guaranteed fixed-latency properties.

Background and aims: Pharmacotherapy can be an important part of the continuum of care for alcohol use disorder (AUD). The Swedish universal health-care system emphasizes provision of care to marginalized groups. The primary aim was to test associations of neighborhood deprivation and disadvantaged social status with receipt of AUD pharmacotherapy in this context. Design: Data from linked populati

The demand for developing creativity among doctoral students is found in a number of educational policies all over the world. Yet, earlier studies on Swedish doctoral education suggest that doctoral students’ creativity is not always encouraged. Based on a critical hermeneutic approach and cases in four different disciplines, the aim of this study was therefore (1) to explore different shapes of d

One of the key-principles of the iron-sulphur world theory is to bring organic molecules close enough to interact with each other, using the surface of pyrite as a substrate in a hydrothermal setting. The present paper explores the relationship of pyrite and organic matter in a hydrothermal setting from the geological record; in hydrothermal calcite veins from Carboniferous limestones in central I
