Synthetic xylan-binding modules for mapping of pulp fibres and wood sections.

Background The complex carbohydrate composition of natural and refined plant material is not known in detail but a matter that is of both basic and applied importance. Qualitative assessment of complex samples like plant and wood tissues requires the availability of a range of specific probes. Monoclonal antibodies and naturally existing carbohydrate binding modules (CBMs) have been used in the pa

Radiation dose reduction in CT of the brain: can advanced noise filtering compensate for loss of image quality?

Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method

An evaluation of measures for quantifying map information

A real-time map must not contain too much information. Therefore, we need measures of map information that could guideline the selection of data layers and the real-time generalisation process. In this paper we evaluate measures of amount of information and distribution of information. The evaluation is performed by (1) defining measures, (2) implementing the measures, (3) computing the measures f

Initial backdraft experiments

A number of large scale backdraft experiments are decribed in this report. A total of 13 experiments have been carried out. During the experiments have several physical properties such as temperature, pressure, gas concentration have been measured. Example graphs are shown in the report. The experimental apparatus as well as the measurments are described in detail in this report. It is difficult t

Using speculation to enhance javascript performance in web applications

JavaScript lets developers provide client-side interactivity in Web applications, but because it is sequential, it can't take advantage of multicore processors. Thread-level speculation (TLS) addresses this issue by enabling the speculation of JavaScript function calls and thus exploits the parallel performance potential multicore processors provide. The authors implemented TLS in the Squirrelfish

Polymorphism in the oxytocin promoter region in patients with lactase non-persistence is not related to symptoms.

BACKGROUND: Oxytocin and the oxytocin receptor have been demonstrated in the gastrointestinal (GI) tract and have been shown to exert physiological effects on gut motility. The role for oxytocin in the pathophysiology of GI complaints is unknown. The aim of this study was to examine genetic variations or polymorphism of oxytocin (OXT) and its receptor (OXTR) genes in patients with GI complaints wi

Virus Entry via the Alternative Coreceptors CCR3 and FPRL1 Differs by Human Immunodeficiency Virus Type 1 Subtype.

HIV-1 infects target cells by binding to CD4 and a chemokine receptor, most commonly CCR5. CXCR4 is a frequent alternative coreceptor (CoR) in subtype B and D HIV-1 infection, but the importance of many other alternative CoR remains elusive. We have analyzed HIV-1 envelope proteins (Env) from 66 individuals infected with the major subtypes of HIV-1 to determine if virus entry into highly permissiv

Process and product in writing-a methodological contribution to the assessment of written narratives in 8-12-year-old Swedish children using ScriptLog.

Twenty-seven children, with typical language development (TLD), 8-10 years old and 10-12 years old, were assessed with keystroke-logging in order to investigate their narrative writing. Measures of the writing process and the written product were used. One purpose was to explore how children produce written narratives in on-line production, and to relate the writing process to the written product.
