Revolving permanent magnet causes rotating particle motion that makes new detection schemes possible in magnetomotive ultrasound

Magnetomotive ultrasound, MMUS, can reveal the presence of a magnetic contrast agent by applying an external magnetic field. If the interaction between the agent and the field is strong enough, a movement that can be detected by ultrasound is induced in the surrounding tissue, thereby inferring the contrast agent distribution. Electromagnets have been used to generate the necessary magnetic field,

Green Transformation: Lessons from the Fuel Cell Innovation System in Taiwan

This study applies the technological innovation system framework to the case of the fuel cell sector in Taiwan. Many Asian latecomers, such as Taiwan, tend to adopt a top-down approach to emphasize the importance of environmental issues but the result is limited. We aim to take Taiwan’s fuel cell innovation system as an example to explore why Taiwan has formulated a technological innovation system

SimCA∗ : A control-theoretic approach to handle uncertainty in self-adaptive systems with guarantees

Self-adaptation provides a principled way to deal with software systems' uncertainty during operation. Examples of such uncertainties are disturbances in the environment, variations in sensor readings, and changes in user requirements. As more systems with strict goals require self-adaptation, the need for formal guarantees in self-adaptive systems is becoming a high-priority concern. Designing se

Pharmacokinetics of glibenclamide and its metabolites in diabetic patients with impaired renal function

BACKGROUND: Glibenclamide (Gb) may provoke long-lasting hypoglycaemic reactions, and one of the known risk factors is impaired renal function. We have demonstrated Gb to have a terminal elimination half-life of 15 h, and the main metabolites have a hypoglycaemic effect. With few exceptions, detailed studies on second generation sulphonylureas in diabetics with impaired renal function are lacking.

Sexual professionalism: for whom? The case of sexual facilitation in Swedish personal assistance services

Sexuality is a taboo subject in disability services, leading to insecurity for both service users and personnel about how to handle upcoming situations. In Sweden, there is also a lack of policy in this area, highlighting the need to study sexuality both as an individual and a political, and in this case also, depoliticized issue. A critical feminist policy analysis reveals that norms around disab

The typology of sound symbolism : Defining macro-concepts via their semantic and phonetic features

Sound symbolism emerged as a prevalent component in the origin and development of language. However, as previous studies have either been lacking in scope or in phonetic granularity, the present study investigates the phonetic and semantic features involved from a bottom-up perspective. By analyzing the phonemes of 344 near-universal concepts in 245 language families, we establish 125 sound-meanin

Quantitative characterization of aberrations in x-ray optics

Due to the weak interaction of X-rays with matter and their small wavelength on the atomic scale, stringent requirements are put on X-ray optics manufacturing and metrology. As a result, these optics often suffer from aberrations. Until now, X-ray optics were mainly characterized by their focal spot size and efficiency. How- ever, both measures provide only insufficient information about optics qu

Elektronisk publicering och institutionella arkiv. Stipendierapport från Kalifornien

Electronic publishing and institutional archives – a scholarship report from CaliforniaIn June 2005 Linda Gustafsson and Kristina Lindgren had the opportunity to make a one week visit to the library at Caltech University, Pasadena in California. The aim was to see how the library staff worked with e-publishing together with the researchers at the campus. As researchers are an important user group

Selective mode of action of guanidine-containing non-peptides at human NPFF receptors

The binding pocket of both NPFF receptors was investigated, focusing on subtype-selective behavior. By use of four nonpeptidic compounds and the peptide mimetics RF9 and BIBP3226, agonistic and antagonistic properties were characterized. A set of Ala receptor mutants was generated. The binding pocket was narrowed down to the upper part of transmembrane helices V, VI, VII and the extracellular loop

Expression of the homeobox engrailed gene during the embryonic development of the nervous system of the trout (Salmo fario L.)

The expression of the engrailed homeobox gene during trout embryogenesis has been examined using immunohistochemistry and the monoclonal antibody 'Mab 4D9'. Engrailed has been suggested to play an important role during development by controlling position-specific characteristics in the CNS of the early embryo. In the present study we have analyzed the expression of engrailed at 5 stages of embryon

The fragmentation of facts and infrastructural meaning-making : New demands on information literacy

Introduction. This paper presents a theory-driven discussion on the role of facts in society, couched between a brief historical overview and a discussion of the contemporary situation, exemplified in particular by openly available web-based fact services. Implications for the conceptualisation of information literacy – and in particular information literacy in relation to today’s dominant algorit
