20th century massification of higher education and research in academia is said to have produced structurally stratified higher education systems in many countries. Most manifestly, the research mission of universities appears to be divisive. Authors have claimed that the Swedish system, while formally unified, has developed into a binary state, and statistics seem to support this conclusion. This

V/P(SPECT) has the potential to become a first hand tool for diagnosis of pulmonary embolism based on standardized technology and new holistic interpretation criteria. Pretest probability helps clinicians choose the most appropriate objective test for diagnosis or exclusion of PE. Interpretation should also take into account all ventilation and perfusion patterns allowing diagnosis of other cardio

AIM: To assess the prognostic value of repetitive serum samples of neuron specific enolase (NSE) and S-100B in cardiac arrest patients treated with hypothermia. METHODS: In a three-centre study, comatose patients after cardiac arrest were treated with hypothermia at 33 degrees C for 24h, regardless of cause or the initial rhythm. Serum samples were collected at 2, 24, 48 and 72h after the arrest a

Immuno-supported liquid membrane (immuno-SLM) extraction is a new technique that makes use of antibody (Ab)–antigen interactions as the "extraction force" to drive the mass transfer in a selective way. In immuno-SLM, anti-analyte (Ag) Abs are introduced into the acceptor phase of the SLM unit to trap the Ag that passes from the flowing donor through the SLM into the stagnant acceptor. The amount o

This thesis aims at describing the developmental patterns of text production in four text types: spoken and written narrative texts, and spoken and written expository texts (n=316), produced by four age groups: 10-year-olds, 13-year-olds, 17-year-olds and university students (n=79). It explores material from an experimental study with a cross-sectional design comprising spoken texts recorded on vi

BACKGROUND: Brain edema and intracranial hypertension is deleterious after traumatic brain injury (TBI), but the underlying pathophysiology is complex and poorly understood. One major subject of controversy is the time course and extent of blood-brain barrier (BBB) dysfunction following trauma, and previous studies in humans have only provided semi-quantitative data. The objective of the present s

BACKGROUND: The transit of blood through the beating heart is a basic aspect of cardiovascular physiology which remains incompletely studied. Quantification of the components of multidirectional flow in the normal left ventricle (LV) is lacking, making it difficult to put the changes observed with LV dysfunction and cardiac surgery into context. METHODS: Three dimensional, three directional, time

Alfa Laval är ett ledande industriföretag inom flera viktiga teknologier såsom: separation, pumpar, och värmeöverföring. Detta genom att tillverka produkter till t.ex. vattenrening, pastörisering, och produktion och överföring av energi, som i sin tur bidrar till ökat välstånd i världen. En av Alfa Lavals mest centrala produkttyper är värmeväxlare för värmeöverföring mellan vätskor och gaser. Ett Alfa Laval’s head office in Lund, Sweden, is the centre for research, development, and production of one of their key technologies: heat exchangers. The most common of these are the gasketed plate heat exchangers (GPHE). In these the liquid channels between heat transfer plates are sealed using rubber gaskets. The sealing ability of these gaskets are thus highly important for the performance of th

Many actors in the construction sector as well as in the research community emphasize the importance of experience feedback and knowledge building in order to streamline and improve the working methods. Taking advantage of positive experiences, sharing them with colleagues and documenting them within the organisation can be useful for future projects. On the other hand, negative experiences should

We have studied the nocturnal flight behaviour of the common swift (Apus apus L.), by the use of a tracking radar. Birds were tracked from Lund University in southern Sweden during spring migration, summer roosting flights and autumn migration. Flight speeds were compared with predictions from flight mechanical and optimal migration theories. During spring, flight speeds were predicted to be highe

En konkurrensklausul är en förpliktelse i konkurrensförebyggande syfte och är ofta förekommande vid företagsöverlåtelser. Vid företagsförvärv som innefattar goodwill och/eller know-how uppkommer ett behov för köparen att söka skydd mot att säljaren, med sitt försprång, efter förvärvet inte startar upp en ny konkurrerande verksamhet. Den rådande konkurrenssituationen kan vara en förutsättning för aA non-competition clause is an undertaking in competition prevention and is frequently used in a company transfers. In the case of company acquisitions that include goodwill and/or expertise, a need arises for the buyer to seek protection that the vendor, with its lead, does not start up a new, competing business after the acquisition. The current competitive situation may be a prerequisite for th

By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. Pyridine dissociation was studied for pyridine and for pyridine mixed with p

För att kunna begränsa brandspridningen och bidra till brandskyddet delas en byggnad oftast in i brandceller. För att vid utrymning kunna ta sig till en säker plats kommer personerna som försöker ta sig ut troligtvis passera genom en öppning i brandcellsgräns. För att kunna bibehålla brandcellsgränsen trots användande av dörrar, fönster och andra öppningar finns det vissa krav på utformning av desIn most of the studies that are made for pedestrian flow through doors, reaserchers have just looked at the flow through oppenings without doors. This study aims to figure out how much impact the configuration of the door has on pedestrian flow. The configurations that have been examined are open doors, free swinging doors, doors that open inwards, doors that open outwards and the differences betw

Impairment of normal hematopoiesis and leukemia progression are 2 well-linked processes during leukemia development and are controlled by the bone marrow (BM) niche. Extracellular matrix proteins, including laminin, are important BM niche components. However, their role in hematopoiesis regeneration and leukemia is unknown. Laminin α4 (Lama4), a major receptor-binding chain of several laminins, is

Väpnade aktörer, terrorism och illegal handel (med människor, narkotika och vapen) är alla företeelser som, i varierande omfattning, florerar i fallerade stater. Dessa företeelser återfinns inte minst i Colombia, som trots det inte bedöms vara fallerad. Uppsatsens syfte är att påvisa behovet av kvalitativa och kontextspecifika studier, då vår förförståelse är att analyser av fallerade stater, som

Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed. Forms of event-based control have been used in prac
