In this work, we report for the first time the rotational coherent anti-Stokes Raman spectroscopy (CARS) spectrum of water vapor, recorded through experiments at 400K and 670K for Raman shifts up to 600cm(-1). Using the standard dual-broadband pure rotational CARS approach, the resonant structure was overwhelmed by a strong non-resonant background. By employing a polarization technique, this backg

The identification of the regions where vector-borne diseases are transmitted is essential to study transmission patterns and to recognize future changes in environmental conditions that may potentially influence the transmission areas. SGS1, one of the lineages of Plasmodium relictum, is known to have active transmission in tropical Africa and temperate regions of Europe. Nuclear sequence data fr

Engineers in large-scale software development have to manage large amounts of information, spread across many artifacts. Several researchers have proposed expressing retrieval of trace links among artifacts, i.e. trace recovery, as an Information Retrieval (IR) problem. The objective of this study is to produce a map of work on IR-based trace recovery, with a particular focus on previous evaluatio

It is important that the costs and effort in making a Virtual Reality (VR) model support its purpose in the specific context in which it is used. The present research aims to clarify which properties in VR-models contribute to improved experience of aspects of the model that are relevant in the use context and which therefore improve the models’ usability in the social processes of which they are

Concerns have been raised about the marketization of science through the prevailing funding regime. However, the present article will discuss how it comes that the potentially marketable stem cell science is not more commercialized than what is currently the case. We approach this question by analysing discursive pluralism in defining the value of stem cells within a grant allocation process. More

The possibility of reducing the transient times at grade changes in paper production and machine start-ups on the paper machines has highlighted the need for increased knowledge of the steam supply system. Models in this area have been presented in previous work and it is of interest to compare these models with each other and evaluate them against experimental data. This paper reports on the resu

Popular Abstract in Swedish Isocyanater är en grupp kemiska ämnen som används vid tillverkning av polyuretanplast (PUR). PUR ingår bland annat i färg, lim, lack och skumgummi, vilka förekommer i många olika produkter i vår miljö. Produktionen och användningen av PUR-produkter ökar. Vid den industriella tillverkningen av PUR kan arbetare exponeras för isocyanater och då drabbas av olika besvär så sThe aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. Biomarkers of TDI and MDI were determined as the corresponding amines, toluenediamine (TDA) and methyle

Popular Abstract in Swedish Gående som mellanmänsklig handling Traska, spatsera, flanera, power-gå, ila, dra fötterna efter sig, ta en stärkande promenad eller bara vandra bort i tankarna för en kort stund. Att gå är en komplex handling som omfattar allt från upplevelsen av marken som vi går på till människorna vi möter. Både när vi är ute och går själva eller tillsammans med andra så förhåller vThere is a lack of attention toward the diversity in experiences of architecture that are expressed through walking. Through the application of autoethnography and critical perspectives of queer and feminist theory, this dissertation develops a method for investigating experiences of architecture in regard to the activity of walking. In addition, this thesis addresses the influence of form, materi

Popular Abstract in Swedish I avhandlingen presenteras ett matematiskt ramverk för analys av datagenomströmning i paket-baserade radionät som stör varandra. Tidigare forskning om prestanda i paketradionät täcker många olika system och aspekter. Tidigare publicerade arbeten har dock till stor del varit begränsade till fixa paketlängder. Ramverket som presenteras i avhandlingen tillåter detaljerad aIn this thesis, a probabilistic framework is presented and used for analysis of the throughput of interfering packet-based radio networks, referred to as packet radio networks (PRNs). Previous research on the performance of PRNs covers a wide variety of systems and aspects in varying levels of detail. However, the work presented in the literature has mostly been limited to fixed packet lengths. Th

Hand prostheses that are currently available on the market are used by amputees to only a limited extent, partly because of lack of sensory feedback from the artificial hand. We report a pilot study that showed how amputees can experience a robot-like advanced hand prosthesis as part of their own body. We induced a perceptual illusion by which touch applied to the stump of the arm was experienced

A rapid and sensitive assay was developed for the detection of amphetamine in plasma and urine. The method relies on the principle of competitive ELISA (enzyme-linked immunosorbent assay). A flow microchip with a total volume of 7 µL was used for the development of a chemiluminescent ELISA technique. Solutions, samples, and the chemiluminescence substrate were injected by a flow system, and a phot

Simultaneous saccharification and fermentation (SSF) is an interesting option for ethanol production from lignocellulosic materials. To meet desired overall yields during ethanol production from lignocellulosic materials, it is important to use both hexoses and pentoses. This can be achieved by co-fermentation of sugars in SSF, so called SSCF (simultaneous saccharification and co-fermentation), us

Square cross-section ribbed channels with deflectors are computationally simulated to determine their optimal configuration for enhancing heat transfer with minimized pressure drop penalties. In this study, the channel inlet Reynolds number ranges from 8,000 to 24,000. The influence of deflector arrangement on the overall performance characteristics of ribbed channels is investigated with six diff

The importance of rare earth elements in modern technological industry grows, and as a result the interest for developing separation processes increases. This work is a part of developing chromatography as a rare earth element processing method. Process optimization is an important step in process development, and there are several competing objectives that need to be considered in a chromatograph
