Background and Objective: In this study a newly developed microprocessor controlled power regulation and thermometry system integrated with a diode laser (805 nm wavelength) was evaluated with respect to temperature distribution, effectiveness of regulation, and ability to predict temperature distributions by computer simulation. Study Design/Materials and Methods: Experiments were performed in gr
Objective. Chronic obstructive pulmonary disease (COPD) continues to be an important cause of morbidity, mortality and healthcare costs in the western world. Although smoking is an important trigger of COPD, other factors such as chronic inflammation and malnutrition are known to influence its development. Because coeliac disease (CD) is characterized both by dysregulated inflammation and malnutri

BACKGROUND: Lung mast cells are stereotypically divided into connective tissue (MCTC) and mucosal (MCT) mast cells. This study tests the hypothesis that each of these subtypes can be divided further into site-specific populations created by the microenvironment within each anatomic lung compartment. METHODS: To study mast cells under non-inflamed conditions surgical resections and bronchial and tr
The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. The concept of Homog
This work presents an analysis of phase noise in the 1/f(2) region displayed by both single-ended and differential bipolar Colpitts oscillators. Very accurate and rigorous symbolic phase noise expressions are derived, enabling a deeper insight into the major mechanisms of phase noise generation, and providing new tools for design optimization. Phase noise expressions for the cross-coupled differen
A 15N tracing model was developed to analyse nitrous oxide (N2O) dynamics in terrestrial ecosystems, which build on previous tracing models for the quantification of the main mineral nitrogen (N) transformations and soil nitrite (NO2 -) dynamics. The N2O dynamics in the model are directly associated with three NO2 - sub-pools. Four pathways for N2O production in soil were considered in the model:
Introduction. This paper examines and synthesizes previous research in scientific collaboration, scholarly communication, scientific collaboratories, scientific disciplines, invisible colleges and virtual communities to identify factors that may impact the design, adoption and use of a collaboratory within librarianship and information science. Results. A taxonomy of factors that appear to impact
Popular Abstract in Swedish Förmågan att planera med en medveten mental simulering har ansetts vara unikt mänsklig sedan Aristoteles. När människor planerar för psykologiska eller fysiologiska driftstillstånd som de för närvarande inte upplever, tror man att de använder sig av så kallad episodisk framförhållning. Den episodiska framförhållningen är en del av det större episodiska kognitiva systemeThe ability to plan for future, not currently experienced, mental or physiological states has been regarded as unique to humans. When humans plan for such states it has been hypothesized that they make use of what has been known as episodic foresight. Episodic foresight is a part of the episodic cognitive system, which also includes episodic memory. The defining feature of this system is so-called
Främsta orsakerna till satsningar på videoövervakningslösningar i detaljhandeln är en vilja att minska oönskade förluster i form av svinn och olika typer av kriminalitet riktad mot butiker. Det visar en studie utförd av forskargruppen Lusax vid Lunds universitet. Studien visar också att den svårtolkade lagstiftningen är ett hinder för bredare användning av videoövervakning.
