Diagnostic measurements and pharmacokinetic studies were performed in 17 patients with various kinds of malignant, premalignant and benign lesions in the head and neck region by means of point monitoring laser-induced fluorescence. For marking different types of tissue, delta-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) was used. The ALA-induced PpIX synthesis was monitored at differ
The heat transferred to the turbine blade is substantially increased as the turbine inlet temperature is increased. Cooling methods are therefore much needed for the turbine blades to ensure a long durability and safe operation. The blade tip region is exposed to the hot gas flows. A common way to cool the tip is to use serpentine passages with 180-deg turn under the blade tip cap taking advantage
Popular Abstract in Swedish Av pedagogiska skäl har anförts att det finns behov av mer kunskaper om människans tänkande om och förhållningssätt till munhälsa och tandvård. Syftet med denna undersökning var att undersöka och beskriva vuxna människors subjektiva tänkande om och förhållningssätt till munhälsa för att belysa faktorer som bidrar till eller utgör hinder för förändring av handlingsberedsThe need, for health educational reasons, of obtaining a more adequate understanding of how people think and act in connection with questions of dental health and professional dental care has been emphasized. The present study examines the attitudes and conceptions of adult individuals regarding their own dental health, as well as measures they take to further it. The aim is to elucidate factors t
Popular Abstract in Swedish Hur slutar det? Är inte detta en fråga vi ofta vill ha besvarad? Så är åtminstone fallet i min avhandling, närmre bestämt gäller det här slutet på kromosomerna, de så kallade telomererna. Telomerer definieras som den DNA/proteinstruktur som avslutar linjära kromosomer. Gener återfinns ej i denna region vilken dock har andra viktiga funktioner. Kromosomer utan telomerer Telomeres in Chironomus consist of long complex tandem DNA repeats, which in C. pallidivittatus have been shown to extend to the extreme end of chromosomes. In C. pallidivittatus the telomeric repeats are present in large blocks, 50-200kb in size, most of them belonging to four major subfamilies. The main issue of this thesis has been to elucidate possible functional roles for these different subf
Finite element analysis in acoustics, structure–acoustics, and structure–hydroacoustic engineering applications leads to large systems of equations, and is still a challenge to current high-performance computer systems. The demands for extremely large models are due to large physical domains or the desire to resolve high-frequency levels, at least as long as the different modes are separated, say
The development of oncolytic viruses has recently made great progress towards being available to cancer patients. With the breakthrough into clinics, it is crucial to analyze the existing clinical experience and use it as a basis for treatment improvements. Here we report clinical data from 290 patients treated with oncolytic adenovirus. Using clinical variables and treatment characteristics, we c
We use Granger causality to investigate the influences of external forcings on subdecadal variability of regional near-surface air temperature (SAT) in past millennium simulations (period 850–1850 A.D.) of the Coupled Model Intercomparison Project Phase 5 (CMIP5) models. Our results strengthen the conclusion for robust influence of volcanic forcing on SAT during preindustrial times of the last mil
Objectives. We investigated whether comorbidity burden of comatose survivors of out-of-hospital cardiac arrest (OHCA) affects outcome and if comorbidity modifies the effect of target temperature management (TTM) on final outcome. Design. The TTM trial randomized 939 patients to 24 h of TTM at either 33 or 36 °C with no difference regarding mortality and neurological outcome. This post-hoc study of
Background: Compression of the ulnar nerve at elbow is frequently treated with simple decompression. Knowledge about factors influencing results of surgery of the nerve is limited and contradictory. The primary aim was to evaluate outcome of simple decompression of the nerve using a QuickDASH questionnaire, and to investigate any influence of smoking, gender, and preoperative electrophysiological
We investigate the momentum and energy budget of stellar feedback during different stages of stellar evolution, and study its impact on the interstellar medium (ISM) using simulations of local star-forming regions and galactic disks at the resolution affordable in modern cosmological zoom-in simulations. In particular, we present a novel subgrid model for the momentum injection due to radiation pr
Purpose: How national culture induces entrepreneurship and business growth remains elusive in research. Questions remain, for example, how can we determine whether a given national culture is good or bad for entrepreneurial activities? What are those pro-entrepreneurship national culture dimensions that could be promoted across nations? These questions are yet open for discussion. The purpose of t
Metal matrix composites (MMCs) possess excellent material properties due to the combination of metals and reinforcing phases, yet this reduces their machinability. Numerous studies have shown that, due to the ploughing effect of the cutting tool, the edge effect can directly impact the material removal mechanism and the generation of surface integrity. However, the influence of different cutting-e
Listening is often ignored and not understood as an organizational strategic resource. In this conceptual article, we explain why listening is downplayed by combining the two research fields Service Management and Strategic Communication. We propose that organizations embrace service logic as a perspective of managing organizations. Service logic has a stakeholder-centric approach to value creatio
The widespread contamination of urban soils by airborne microplastics (MPs) is an emerging environmental issue, particularly in urban allotment gardens with home-grown food. This study investigates the vertical distribution of MP in three such gardens in Berlin, Germany, over 90 days. Soil samples were collected at three depths (0-1 cm, 1–15 cm, and 15–30 cm) and analyzed for MP composition and oc
Groundwater drought, a significant natural disaster in arid and semi-arid regions, contributes to numerous consecutive issues. Due to the inherent complexity of groundwater flow systems, accurately quantifying and describing this phenomenon remains a challenging task. As a result of excessive agricultural development, the Marand Plain in northwestern Iran is experiencing both groundwater drought a
The Gullåkra wetland is located around 5 km south of the modern city of Lund and around 2.7 km east of the important Iron Age settlement of Uppåkra in Scania, southern Sweden. In the 1840s, a remarkable discovery was made in the wetland: a bronze lur dated to c. 1300 BCE, along with a boat and the bones of a large animal offering. As Bronze Age boats are exceedingly rare, this discovery makes the
Tetra Pak is a world leader in providing innovative packaging solutions and processing technologies and has been so for a very long time. It is well – known that the material used for packaging purposes gets subjected to high temperature and pressure during folding and filling which could compromise the integrity of the material. The polymer layer in the packaging material acts as a barrier, and t
The historical development of responsibility for wars and aggressive acts has seen a shift of focus during the last century. Where the attention was previously focused on the unlawfulness of a State act (the Act of Aggression), the attention is now on the involvement and responsibility of individuals. The topic of this thesis is to follow the development of the possibility to hold those behind Sta
