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

Contact and isolation in hunter-gatherer language dynamics: evidence from Maniq phonology (Aslian, Malay Peninsula)

Maniq, spoken by 250-300 people in southern Thailand, is an undocumented geographical outlier of the Aslian branch of Austroasiatic. Isolated from other Aslian varieties and exposed only to Southern Thai, this northernmost member of the group has long experienced a contact situation which is unique in the Aslian context. Aslian is otherwise mostly under influence from Malay, and exhibits typologic

The mandibular third molar. Dentists' judgement in the removal of asymptomatic molars

The aim was to study dentists' judgement on the removal of and on the development of pathology associated with asymptomatic mandibular third molars. Thirty general dental practitioners (GDPs) and 10 oral surgeons were asked to judge 36 molars with equal distribution of three cues: patient's age, angular position and degree of impaction of the molar. Rating on a VAS was found to be an appropriate m

Keeping an eye on gestures: Visual perception of gestures in face-to-face communication

Since listeners usually look at the speaker's face, gestural information has to be absorbed through peripheral visual perception. In the literature, it has been suggested that listeners look at gestures under certain circumstances: 1) when the articulation of the gesture is peripheral; 2) when the speech channel is insufficient for comprehension; and 3) when the speaker him- or herself indicates t

To investigate the molecular deficiency in MMR genes associated to Lynch syndrome.

Clinical Manifestations and Epidemiology of the New Genetic Variant of Chlamydia trachomatis.

BACKGROUND:: In 2006, a new genetic variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. Clinical manifestations of this infection were studied in a high-risk population. METHODS:: During 2007, a prospective case-control study on sexual lifestyle and urogenital infections was performed at the Centre for Sexual Health (CSH), affiliated to Malmo University Hospital. A total of 629 C. tr

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

Long term predictive values of cytology and human papillomavirus testing in cervical cancer screening: joint European cohort study.

OBJECTIVE: To obtain large scale and generalisable data on the long term predictive value of cytology and human papillomavirus (HPV) testing for development of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+). DESIGN: Multinational cohort study with joint database analysis. SETTING: Seven primary HPV screening studies in six European countries. PARTICIPANTS: 24,295 women attending cerv
