Measurements are reported of the production of dijet events with a leading neutron in ep interactions at HERA. Differential cross sections for photoproduction and deep inelastic scattering are presented as a function of several kinematic variables. Leading order QCD simulation programs are compared with the measurements. Models in which the real or virtual photon interacts with a parton of an exch

Abstract in UndeterminedAims: To assess how a 10 year extension of the follow up period affected cancer incidence in the Swedish leather tanning cohort. Methods: A cohort of 2027 tannery workers (of which 482 were women) who had been employed for at least one year between 1900 and 1989 at one of three Swedish leather tanneries, was established. The start of observation varied between 1958 and 1966

Aim. To explore patients' evaluation of a specialized diabetes clinic for management of women with gestational diabetes born in Sweden and the Middle East and its contribution to a decreased level of stress and improved coping capability to promote health in patients receiving care. Background. No studies comparing patients' perceptions of healthcare in women of different origin with gestational

Phosphonic acid (H3PO3) is a candidate as an anchor group that can be used to bind a wide range of molecules to TiO2 surfaces, with practical applications for example in dye-sensitized solar cells. Adsorption geometries and energies of H3PO3 on the TiO2 anatase (1 0 1) surface have therefore been investigated using quantum-chemical periodic hybrid ab initio Hartree Fock density functional theory c

Giant cell reparative granuloma (GCRG) is an uncommon lesion most often affecting the jaw but also the small bones of the hands and feet. GCRG overlaps clinically and radiographically with other giant cell-rich tumors such as giant cell tumor of bone (GCTB) and aneurysmal bone cyst (ABC). In the only case of a cytogenetically investigated GCRG reported previously, a balanced translocation involvin

Spatially and spectrally resolved cathodoluminescence in the scanning electron microscope is a very powerful technique for studying the optical properties of semiconductor structures, especially low-dimensional structures (structures with nanometre-sized features). The technique is generally nondestructive and can be combined with the normal imaging capabilities and analysis possibilities of the s

The purpose of the present study was to develop a new model of the initial part of an evacuation process, i.e., the pre-movement phase. A new method for estimating the pre-movement time was also going to be proposed. In the initial part of the study an inventory of existing models of human behaviour during fire evacuation was performed. This was followed by a literature review about helping behavi

European air traffic control is undergoing changes in organization and technology in order to increase efficiency in air traffic. Change processes can have a negative impact on existing safety cultures, the foundations of safety work, and on safety. This paper reports on an assessment of safety culture at one administrative and two operative units in a Swedish air traffic control setting, using qu

This report has a two-fold objective. -To identify the changing risk management needs in the private and public sectors and the corresponding needs for development of risk analysis methods and related practices. -To list examples of projects where Nordic co-operation between industry, authorities and universities can be effective for increasing the contribution of risk management to industrial gro

I föreliggande rapport redovisas en fördjupad studie av hur en vattenavvisande impregnering fungerar när det finns sprickor i fasaden.

The prevalence of chronic illness of all 6,080 0-15-year-old children in a defined geographical area in southern Sweden was studied. Information on the health status of the children was obtained from health and medical records, interviews with the district and school nurses and questionnaires to the parents. Chronic illness was defined as a disability interfering with normal life and/or demanding

The present study shows the probable intrauterine infection with Chlamydia trachomatis in a premature infant born in the 29th week of gestation. Chlamydiae were isolated from lung tissue collected at sterile autopsy and also demonstrated in sections of such tissue by immunofluorescence tests using monoclonal antibodies.

Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. In Finland, the sperm concentration was found to be substantially higher than in Denmark. In parallel, the incidence of testicular cance
