The objective of this chapter is to contribute to the understanding of the growth of this global data-driven market ecology, mainly in order to pinpoint important regulatory challenges, where individual choice and agency, as well as competition, seem undermined. Truly, this development holds many promises for new innovation, some more disruptive than others, but also poses challenges that in this
This paper presents an acoustofluidic chip for the sorting of bacteria from protozoa in water using standing acoustic waves. The size-based acoustophoretic sorting method provides a means for sample pre-concentration, which is vital for real-time, on-site monitoring of drinking water quality and preventing outbreak of waterborne diseases. In practice, high throughput and high recovery pre-concentr
Denna rapport redovisar en förstudie till SNS fleråriga forskningsprojekt som undersöker hur värdet av nya läkemedel kan bedömas ur ett brett samhällsperspektiv. En slutsats av förstudien är att det finns goda möjligheter att få bättre svar på många av de policyfrågor som ställs i läkemedelspolitiken, t ex om förskrivning och offentlig subventionering av nya läkemedel. De omfattande svenska patien
Many neurons typically fire action potentials in brief, high-frequency bursts with specific consequences for their synaptic output. Here we have examined short-term plasticity engaged during burst activation using electrophysiological recordings in acute rat hippocampal slices. We show that CA3-CA1 glutamate synapses exhibit a prominent depression of presynaptic release probability for approximate
Background: This study investigates gaze behaviour in child dialogues. In earlier studies the authors have investigated the use of requests for clarification and responses in order to study the co-creation of understanding in a referential communication task. By adding eye tracking, this line of research is now expanded to include non-verbal contributions in conversation. Aims: To investigate
The research group from Humanities laboratory at Lund University, Sweden, presents three strands of research on language and cognition where eye-tracking methodology has been used as a window on the mind. The paper includes: (1) eye tracking studies on picture viewing and picture description showing the dynamics of how speakers perceive, conceptualize and spontaneously describe complex visual scen
In upholstery applications, it is common to use polyurethane (PUR) foam when flexibility is desired. However, as PUR is a carbon-based material produced using toxic isocyanates, it is environmentally beneficial to replace PUR with bio-based alternatives. The challenge, however, lies in finding suitable bio-based replacement materials, capable of mimicking the foam-like functionality of PUR since m
We have studied drug release and skin permeation from several different liquid crystalline lipid formulations that may be used to control the respective release rates. We have studied the release and permeation through human skin of a water-soluble and amphiphilic drug, propranolol hydrochloride, from several formulations prepared with monoolein and phytantriol as permeation enhancers and controll
Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. This thesis presents an interactive prototyping tool called
Popular Abstract in Swedish Inbyggda styrsystem finns idag överallt omkring oss. Moderna bilar, cd-spelare och mobiltelefoner är bara några exempel på produkter som inte skulle fungera utan datorbaserade reglersystem. Dock karaktäriseras dessa system ofta av begränsade beräkningsresurser, till följd av tillverkarnas behov att minimera produktionskostnaden. Samtidigt vill man införa mer och mer funThis thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. A feedback scheduling strategy is presented, which uses feedback from plant states to distribute computing resources optimally among a set of co
Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease with no known single predisposing genetic factor shown in all cases. Recently, a single nucleotide polymorphism (SNP) T393C in the GNAS1 gene has been reported to have a clinical impact on CLL progression and overall survival. In order to further investigate the T393C SNP in CLL, we have genotyped 279 CLL cases and correlated
Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c
The aim of this sociology of law-orientated article is to analyse and describe legislative and regulatory processes concerning the task given to schools focusing on environment and sustainable development. We are describing the policy-making processes in this field from 1990 to 2011. The study involves key interviews and content analysis of national policy documents as well as legal sources, in or
Cutaneous Human Papillomavirus (HPV) types have been associated with non-melanoma skin cancer (NMSC), including a previous nested case-control study using HPV serology with bacterially derived fusion proteins with the major HPV capsid protein L1 (GST-L1). However, HPV serology using conformationally intact pseudovirions has been shown to correlate better with natural infection. Prospective studies

Popular Abstract in Swedish Nollvisionen antagen av Sveriges riksdag fastlägger att ingen skall behöva dödas eller skadas svårt i trafiken i Sverige. Införande av detta begrepp förskjuter fokus från trafikolyckorna till konsekvenserna av trafikolyckorna och härmed skapas förutsättningar för ett paradigmskifte i trafiksäkerhetsarbetet. För att åstadkomma önskade förändringar är det nödvändigt och bThe over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. Ot
The objective of this study was to describe environmental barriers and investigate the nature of accessibility problems in housing among single-living, very old people (N = 1,150) in urban regions in three European countries (Sweden, Germany, Latvia), in a one-year perspective. A specific feature of this study is the explicit conceptual differentiation between environmental barriers and accessibil
