Occupational health epidemiology in the Nordic countries – status and trends

This overview aims to give an indication of the current status and trends in occupational health epidemiology in the Nordic countries. As indicated by recent biometric reviews, Nordic countries currently rank among the top five globally in terms of research output on the work environment. However, birth-cohort effects and rapid change in institutions and funding may seriously jeopardize this posit

Searching for binary and nonbinary block and convolutional LDPC codes

A unified approach to search for and optimize codes determined by their sparse parity-check matrices is presented. Replacing the nonzero elements of a binary parity-check matrix (the base or parent matrix) either by circulants or by companion matrices of elements from a finite field GF(2m), we obtain quasi-cyclic low-density parity-check (LDPC) block codes and binary images of nonbinary LDPC block

Using simulation for assessing the real impact of test-coverage on defect-coverage

The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How

Bit selective erasure of photon-echo data using Ti : S and dye laser systems: a comparative analysis

It is investigated how the erasure efficiency for a single bit of data, stored using photon echoes, depends on the data writing time and data storage time. A comparative analysis of the erasure efficiency using a Ti:S laser system and a ring dye laser system is performed. The results clearly establish that the Ti:S laser system, which has a narrower line width than the dye laser system, could be u

Impact of MDCT with intravenous contrast on the survival in patients with acute superior mesenteric artery occlusion.

Acute thromboembolic occlusion in the superior mesenteric artery (SMA) is a condition with high mortality and morbidity. Multi-detector computerised tomography with intravenous contrast enhancement (MDCTiv) may improve diagnostic accuracy and survival. Patients with acute SMA occlusion were identified between 2004 and 2008 at Malmö University Hospital, Sweden. Medical records were analysed. Each M

The Fragility of Religious Freedom

One implication of freedom of religion is that the State must accept a variety of religious beliefs and practices. Yet, not everything can be accepted. One way of dealing with such a conflict is to state that freedom of religion is absolute in so far that it does not infringe upon some other more important value. Another way is to limit what is considered ‘religious.’ Both these ways are insuffici

Prevalence of dementia subtypes: A 30-year retrospective survey of neuropathological reports.

We investigated the distribution of neuropathologically defined dementia subtypes among individuals with dementia disorder. The neuropathological reports were studied on all patients (n=524; 55.3% females; median age 80, range 39-102 years) with clinically diagnosed dementia disorder who underwent complete autopsy including neuropathological examination within the Department of Pathology at the Un

Exit of pediatric pre-B acute lymphoblastic leukaemia cells from the bone marrow to the peripheral blood is not associated with cell maturation or alterations in gene expression.

BACKGROUND: Childhood pre-B acute lymphoblastic leukemia (ALL) is a bone marrow (BM) derived disease, which often disseminates out of the BM cavity, where malignant cells to a variable degree can be found circulating in the peripheral blood (PB). Normal pre-B cells are absolutely dependent on BM stroma for survival and differentiation. It is not known whether transformed pre-B ALL cells retain any
