The purpose of this work is the enhancement of performance by a new design of monolithic heat exchangers under steady-state operating conditions. Heat transfer phenomena and hydrodynamics have been studied and visualized by computational fluid dynamics (CFD). Further, a simple gas distribution system has been analyzed in purpose to find best performance of the exchanger. To achieve this, 3D simula
This paper explores discourses in higher education viewing two pairs of concepts, on the one hand, the concepts of use- vs. exchange value and on the other, the concepts of deep vs. surface learning. Drawing on Yrjö Engeströms’ position of use- vs. exchange value, and his elaboration on the activity system, we assert that any component in an activity system combines two inherent forces which compe
How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i
The paper explores the flux of male homosexual identity between urban subcultures and small rural settings in Sweden. Eve Kosofsky Sedgwick has claimed that we cannot interpret Foucault’s History of Sexuality as if one understanding of sexuality was substituted by another, but that many forms of sexuality coexist in any given time. Inspired by her analysis, this paper claims that a shift between t
BACKGROUND: Although the impact of pancreatic infections in acute pancreatitis has been studied extensively, there are no population-based data on extrapancreatic infections and their potential relation to organ failure. We aimed to study the occurrence of pancreatic and extrapancreatic bacterial infections in acute pancreatitis and their relation to patient outcome. PATIENTS AND METHODS: All pati
Lepidoptera (moths and butterflies) are one of the most diverse groups of organisms on earth. They have conquered all the continents apart from Antarctica. The reasons of such high diversity are still not clear. One of the first steps to study the causes of such evolutionary success is to have a clear idea of their phylogenetic relationships. In this thesis I focus on the diversity of two of the m
Hybrid cauliflower production predominately relies on pollen transfer from hermaphrodite to female lines by honeybees. However, the presence of other pollinators may impact pollination success. Here, we investigate how honeybee visitation frequency and behaviour vary with plant sex and presence of blowflies and affect seed and pod set. We found substantial pollen limitation when honeybees were alo
BACKGROUND: Climate change is set to exacerbate occupational heat strain, the combined effect of environmental and internal heat stress on the body, threatening human health and wellbeing. Therefore, identifying effective, affordable, feasible and sustainable solutions to mitigate the negative effects on worker health and productivity, is an increasingly urgent need. OBJECTIVES: To systematically
During the Second Vatican Council, American Jewish community members impacted the drafting of the declaration on the Catholic Church's attitude toward Jews and Judaism. This article explores the American Jewish Committee's reactions to the drafting and promulgation of the Declaration on the Relation of the Church with Non-Christian Religions (Nostra Aetate) and its contribution to establishing int
