The relation between use of sunscreens, different host factors and malignant melanoma was investigated in a population-based, matched case-control study of malignant melanoma in the South Swedish Health Care Region, which has the highest risk for melanoma in Sweden, between 1 July 1988 and 30 June 1990. In total, 400 melanoma patients and 640 healthy controls aged 15-75 years answered a comprehens

A case-control study of 177 premenopausal and 216 postmenopausal breast cancer patients diagnosed in the southern Swedish Health Care Region between 1981 and 1984, and 195 premenopausal and 254 postmenopausal controls randomly chosen during 1984 from the same population by means of a computerized population register was used to estimate the relations among alcohol consumption, cigarette smoking, a

In a population-based, matched case-control study from the South Swedish Health Care Region, which has the highest risk for melanoma in Sweden, the relation between the use of sunbeds or sunlamps and malignant melanoma was investigated. Between July 1, 1988, and June 30, 1990, a total of 400 melanoma patients and 640 healthy controls aged 15-75 years answered a comprehensive questionnaire containi

This reports presents the results of an excavation conducted next to the west front of the cathedral in Trondheim. In all 11 phases of activity pre-dating the construction of the cathedral were recorded. The earliest features on the site are interpreted as representing part of a late 9th or 10th century farmstead. Thick deposits of soapstone chips are related to various phases of the buildning of

The current state of the water and sanitation sector has put water­related innovations high on the global policy agenda. However, the systemic complexity that typically surrounds such contexts call for actionable knowledge of how to enable and orchestrate innovative solutions by connecting different players via organized networks. In this study we explore and analyse the Water Innovation AcceleratThe current state of the water and sanitation sector has put water-related innovations high on the global policy agenda.

Requirements Engineering has attracted a great deal of attention from researchers and practitioners in recent years. This increasing interest requires academia to provide students with a solid foundation in the subject matter. In Requirements Engineering Education (REE), it is important to cover three fundamental topics: traditional analysis and modeling skills, interviewing skills for requirement

Aquaporins of the TIP subfamily (Tonoplast Intrinsic Proteins) have been suggested to facilitate permeation of water and ammonia across the vacuolar membrane of plants, allowing the vacuole to efficiently sequester ammonium ions and counteract cytosolic fluctuations of ammonia. Here, we report the structure determined at 1.18 Å resolution from twinned crystals of Arabidopsis thaliana aquaporin AtT
