Aim: To analyse incidences and find risk groups in children hospitalized with hand injuries in a national retrospective study. Methods: All children with a primary hand or forearm injury admitted to Swedish hospitals during 1987 - 2001 were retrieved from the Swedish Hospital Discharge Register and analysed as to incidence and characteristics. Results: Among 9855 children included, the median age
Three types of estimator of the second spectral moment of a stationary Gaussian process are considered. The integral estimator is based on the integral of the squared derivative of the process, while crossing estimators make use of the number of upcrossings of zero or nonzero levels. It is shown that the zero-crossing estimator can often compete with the integral estimator in efficiency and that i
Trigeminovascular activation is involved in the pathophysiology of migraine and cluster headache. The marker evaluated best for trigeminovascular activation is calcitonin gene-related peptide (CGRP) in the cranial circulation. It is unknown whether trigeminovascular activation plays any role in cervicogenic headache (CEH). The objective of this study was to investigate CGRP plasma levels in CEH pa
Bacterial diversity of the mucosal biopsies from human jejunum, distal ileum, ascending colon and rectum were compared by analysis of PCR-amplified 16S rDNA clone libraries. A total of 347 clones from the mucosal biopsies were partially sequenced and assigned to six phylogenctic phyla of the domain Bacteria: Firmicutes, Bacteroidetes, Proteobacteria, Fusobacteria, Verrucomicrobia, and Actinobacter
Aims and objectives. The aim was to study the association between gender, extent and content of care, satisfaction, coping and difficulties in the caregiving situation among older (75+) caregivers and to identify clusters of caregivers. The aim was also to explore psychometrically two instruments assessing satisfaction and difficulties in family caregivers. Background. Caregiving is a complicated
Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. However, it suffers from several difficulties, for example, the poor combustion efficiency ? th
We comment on the recent calculations of the pion pole part of the light-by-light contribution to the muon anomalous magnetic moment and we point out where the analysis in our previous work was mistaken.
Using the Implicit Association Test, we investigate whether employers and students possess implicit and explicit negative attitudes and implicit perform-ance stereotypes toward Arab-Muslim men relative to native Swedish men. We also examine if employers and students have implicit and explicit performance stereotypes toward obese individuals relative to people of normal weight. The results demonstr
In this paper a wave splitting technique is applied to a homogeneous Timoshenko beam. The purpose is to obtain a diagonal equation in terms of the split fields. These fields are calculated in the time domain from an appropriate set of boundary conditions. The fields along the beam are represented as a time convolution of Green functions with the excitation. The Green functions do not depend on the
Social phobia is one of the most frequent mental disorders and is accessible to two forms of scientifically validated treatments: anti-depressant drugs and cognitive behavior therapies (CBT). In this last case, graded exposure to feared social situations is one of the fundamental therapeutic ingredients. Virtual reality technologies are an interesting alternative to the standard exposure in social
Background The endothelial ADP receptor P2Y(1) is responsible for a large part of the reactive hyperemia following cardiac ischemia. Tissue plasminogen activator (t-PA) increases during reactive hyperemia. We postulated that the release of t-PA during reactive hyperemia could be mitigated through blocking the coronary endothelial P2Y(1) receptor. Methods t-PA was measured in peripheral arterial bl
Road profiles are analyzed with focus on road characteristics essential for heavy vehicle fatigue assessment. Road profile measurements indicate that roads contain short sections with above-average irregularity. Such rough sections are shown to cause most of the vehicle fatigue damage. An algorithm using a spatial-frequency description is developed to automatically identify rough sections. On the
This report describes the design and implementation of {TinyRealTime}, an event-based real-time kernel for the Atmel AVR ATmega8L 8-bit micro-controller. The kernel is event-based and supports fully preemptive earliest-deadline-first scheduling of tasks. Semaphores are provided to support task synchronization. The focus of the report is on the memory management, timing, and internal workings of th
In comparison with other decapods, the Caribbean spiny lobster Panulirus argus has little diversity in the external morphology of the setae on the mouth apparatus. In mouthpart areas that frequently touch food items only two types of setae can be distinguished: simple setae and cuspidate setae. Simple setae are by far more numerous. The ultrastructural data presented here show that both types of s
