We have developed a method to separate bacteria from red and white blood cells (henceforth collectively called blood cells) using acoustophoresis, for subsequent PCR detection. To maximize throughput, we have now investigated the effect of increased cell concentration on the separation. Increasing the blood concentration drastically decreases bacteria recovery, but we show that this can be remedie

We present a significantly improved acoustophoresis method to separate bacteria from red and white blood cells. As much as 98% of the bacteria were recovered, while only 0.06 % of the red and white blood cells remained. This 1600-fold relative enrichment was achieved by adjusting the center medium density, tightly controlling the chip temperature and stabilizing the fluid flows. This is a crucial

In industries like high-tech and automotive, increasingly more of the product value delivered to the customer is based on a combination of hardware (HW) and software (SW), where SW handles much of the differentiation of capacity and features. The “logistics process” of SW, especially when it merges with HW along the process, has so far been little studied but a problem noticed is the difficulties

This paper describes the RTD project FRR (Friendly Rest Room) which is partly funded by the EU in the Quality of Life programme. The objective of the FRR project is (a) to create prototypes of more user friendly rest rooms for old persons and for persons

In this paper the phenomenon of pluralistic ignorance is discussed and it is argued why it is of relevance for epistemic logic and social psychology. Roughly put, pluralistic ignorance is the case when a group of interacting agents all experience a discrepancy between their private opinions and the perceived opinions of the others. After introducing the phenomenon, numerous features of pluralistic

Human appreciation of nature and natural elements is ubiquitous. The role of emotions in human relationships with nature has received increasing attention within environmental psychology, for example by employing constructs such as affinity with nature. Also, researchers are recognizing the importance of studying emotions for understanding human-wildlife interactions (Jacobs, 2009; Johansson &

Popular Abstract in Swedish Inom en art finns individer av olika kvalitet dvs. med olika förmåga att föra sina gener vidare till nästa generation. Förutom genetiska skillnader, kan sådana kvalitetsskillnader bero på miljömässigt orsakad variation. Av speciellt intresse är effekter som uppstår genom att den tidiga uppväxtmiljön varierar. Dessa effekter har föreslagits vara av vikt för fåglars överlVariation in growth conditions during ontogeny may result in permanent differences in individual quality. This thesis focuses on how starlings are affected by environmental variation during the nestling period. Both landscape differences in food availability and experimental food supplementation affected survival and growth of nestlings. During benign conditions, nestlings reached a larger morphol

There is an urgent need to start generating energy within cities in order to pave the way for a more sustainable and resilient society. Renewable energy by means of active solar energy systems (solar thermal, ST and/or photovoltaics, PV) can be generated using roofs and facades of buildings. In this study, the annual solar energy potential of typical Swedish city blocks was analysed in order to de

Popular Abstract in Swedish Enligt Världshälsoorganisationen (WHO) är en god hälsa ett "tillstånd av fullständigt fysiskt, socialt och mentalt välbefinnande, och inte enbart avsaknad av sjukdom eller funktionshinder". Vår hälsa påverkas under hela vår levnad av en mängd faktorer såsom exempelvis våra gener, biologiska faktorer, sociodemografiska faktorer, beteendefaktorer och livsstil samt miljöfaAbstract: The complexity of health relates to the interplay between numerous factors, e.g., biological and genetic factors, sociodemographic factors, life-style, environmental factors as well as health care services, all possibly acting throughout the life-course. While earlier health theories mainly have focused on adult life style as causes of adult ill-health, life-course research has in recent

Popular Abstract in Swedish Denna avhandling inom forskarutbildningsämnet arbetsmiljöteknik beskriver nyutvecklade provtagnings- och analysmetoder för att undersöka hur reaktionsbenägna luftföroreningar uppkommer och sprids i arbetsmiljön. Antalet människor som drabbas av allergier har ökat de senaste årtiondena. Många av de mekanismer som ger upphov till allergier och överkänslighetsreaktioner kMany sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds. Exposure can occur in many situations, not only at the workplace where the raw materials are handled. The f

Fuel Taxes and the Poor challenges the conventional wisdom that gasoline taxation, an important and much-debated instrument of climate policy, has a disproportionately detrimental effect on poor people. Increased fuel taxes carry the potential to mitigate carbon emissions, reduce congestion, and improve local urban environment. As such, higher gasoline taxes could prove to be a fundamental part of

Information literacy is both a common and an important learning activity with higher education. That said, it is under-theorized as a process and as a path to a product. In order to meet the need for theory, the four panelists will offer four distinct possibilities for theoretical frameworks. While the four frameworks are able to stand alone, there is also the likelihood that they might be melded

We are concerned with software that can self-adapt to satisfy certain reliability requirements, in spite of adverse changes affecting the environment in which it is embedded. Self-adapting software architectures are heavily based on dynamic binding. The bindings among components are dynamically set as the conditions that require a self-adaptation are discovered during the system's lifetime. By ado

For decades, accessibility to the physical housing environment for people with functional limitations has been of interest politically, professionally and for the users Guidelines and norms on accessible housing design have gradually been developed, however the built environment shows serious deficits when it comes to accessibility This study addresses development of a content valid cross Nordic v
