We present age- and gender-specific normative bone status data evaluated by quantitative ultrasound (QUS) in the calcaneus with the Lunar Achilles device and compare these estimates with bone mineral content (BMC) and bone mineral density (BMD) estimated by dual X-ray absorptiometry (DXA). Included were a sample of 518 population-based collected Swedish girls and 558 boys aged 6-19 years. QUS meas

Quantum-beat signals can also be observed when the length of the exciting pulse is not short compared to the Bohr precession period if spontaneous decays during the pulse are important. Experimental demonstration for Zeeman quantum beats in the 6s6p 3P1-6s21S0 ytterbium transition, as well as a simple description of the phenomenon is given. In the same way as quantum beats can be obtained for cohe

It is well known that fast correlation attacks can be very efficient if the feedback polynomial is of low weight. These feedback polynomials can be considered weak in the context of stream ciphers. This paper generalizes the class of weak feedback polynomials into polynomials were taps are located in several groups, possibly far apart. Low weight feedback polynomials are thus a special case of thi

To describe how the included items in three different scales, Downton Fall Risk Index, the short form of Mini Nutritional Assessment and the Modified Norton Scale are associated to severe outcomes as falls, weight loss and pressure ulcers.

Objective: Previous research has shown that elderly and disabled travelers using Special Transportation Services (STS) are injured without being involved in a vehicle crash. In order to estimate the true costs for these vehicle-related injuries, the focus needs to be adjusted towards an incident/traveler-oriented perspective. The aim of the project was thus to utilize such a perspective, in order

The study of alternative and novel techniques for altering selectivity and enhancing sensitivity as well as injection and detection protocols are important in the ongoing development of capillary electroseparation protocols. Some recent research from our laboratory in these fields is presented and discussed in this review. To improve sensitivity an off-line sample enrichment technique utilising so

Objective: Neuronal loss in the locus coeruleus (LC) is common in Alzheimer's disease (AD), dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). The aims of the present study were to investigate LC degeneration in different dementia disorders including vascular dementia (VaD) and frontotemporal lobar degeneration (FTLD), to compare LC degeneration with severity of pathology in A

Today, computed tomography (CT) systems routinely use automatic exposure control (AEC), which modulates the tube current. However, for optimal use, there are several aspects of an AEC system that need to be considered. The purpose of this study was to provide an overview of the Siemens CARE Dose 4D AEC system, discuss practical tips and demonstrate potential pitfalls. Two adult anthropomorphic pha

Background: Renal insufficiency is a serious complication of lithium treatment. Therefore, regular monitoring of plasma (P) creatinine is always part of lithium treatment safety routines. Recently P-cystatin C-estimated glomerular filtration rate (cystatin C-eGFR) had been launched as a preferable alternative to P-creatinine. Aims: To find out which of the two alternatives to prefer in the safety

AIM: Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood METHODS: The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985
