Introduction. We present a prototype collaboratory, a socio-technical platform to support sharing research data collection instruments in library and information science. No previous collaboratory has attempted to facilitate sharing digital research data collection instruments among library and information science researchers. Method. We have taken a socio-technical approach to design, which inclu

OBJECTIVE: There is great need of biomarkers for research and clinical purposes in COPD. This study explored the relationships between ten putative plasma biomarkers of COPD and physiological measures of reduced lung function. METHODS: FEV(1), FVC, residual volume/total lung capacity (RV/TLC) and CO diffusion capacity (D(L)CO) were assessed in 357 subjects from the Swedish Twin Registry. The l

Popular Abstract in Swedish ``Att fela ör mönskligt...'' är början på en sentens som antyder att det krävs någit ytöver det mänskliga för att korrigera fel; sanningen är att det är lika naturligt för människan at korrigera fel som det är att fela, vilket belyses i detta stycke. Trots ett flertal skrivfel är innebörden av texten entydig. Detta beror naturligtvis på att meningsfull svensk text svaraModern communication systems strive to achieve reliable and efficient information transmission and storage with affordable complexity. Hence, efficient low-complexity channel codes providing low probabilities for erroneous receptions are needed. Interpreting codes as graphs and graphs as codes opens new perspectives for constructing such channel codes. Low-density parity-check (LDPC) codes are one

Background: Clinically validated guidelines for the management of head injury in children do not exist, and the treatment is often based upon adult management routines. In order to examine the safety of this procedure, an analysis of clinical factors associated with complications after pediatric head injury was attempted. Method: We performed a descriptive retrospective study, including patients w

Non-compliance with food record submission can induce bias in nutritional epidemiological analysis and make it difficult to draw inference from study findings. We examined the impact of demographic, lifestyle and psychosocial factors on such non-compliance during the first 3 years of participation in a multidisciplinary prospective paediatric study.

ABSTRACT: Presence of a cervical rib in children is extremely rare, particularly when symptoms of compression of the lower trunk of the brachial plexus occur. We present two cases with such a condition, where two young girls, 11 and 16 years of age were treated by resection of the cervical rib after a supraclavicular exploration of the lower trunk of the brachial plexus. The procedure led to succe

Den omtalade globaliseringen förknippas inte bara med snabba finansiella rörelser utan också med ökat antal möten mellan etniska och nationella grupper. Beskrivningen av en sådan ökad kommunikation är ett stående inslag i såväl debatt (Martin & Schumann 1997) som samhällsvetenskaplig teoridiskussion (Bauman 1998, Beck 1998). Samtidigt anses det etniska identitetsbegreppet ha försvagats eller f

Since Abney (1987), generative syntax has invested much interest in the structure of the Noun Phrase, producing numerous theoretical as well as descriptive studies. Within the field of Scandinavian Noun Phrase studies, Delsing (1993) was a groundbreaking work that has since been followed up by several important studies, including Vangsnes et al. (2003) and Julien (2005). This field of inquiry is e

The stepwise commitment from hematopoietic stem cells in the bone marrow to T lymphocyte-restricted progenitors in the thymus represents a paradigm for understanding the requirement for distinct extrinsic cues during different stages of lineage restriction from multipotent to lineage-restricted progenitors. However, the commitment stage at which progenitors migrate from the bone marrow to the thym

Popular Abstract in Swedish Avhandlingen beskriver forskningen kring miniatyriserade enzymreaktorer - nyckelkomponenter i system för diabetsövervakning. Målet är att systemet kontinuerligt och under flera dagar skall kunna mäta glukosstatus hos bäraren. Provtagningstekniken för systemet är mikrodialys; en prob instucken i bukfettvävnaden ger ett prov som innehåller glukos. Analysen av detta prov sThe development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. The glucose turn-over rate was monitored following a colourimetric assay. The advantage, in terms of high surface

Microfluidic systems have become one of the most interesting fields in the research of chemical analysis. Miniaturized systems exhibit numerous practical advantages when compared with traditional batch-scale synthesis such as lower sample volumes, increased control of the reactions and higher sample throughput. This thesis describes the development and applications of a parallel channel microreact
