Gonyostomum semen (Ehrenb) Diesing is a bloom-forming and noxious phytoplankton species, that usually occurs in brown-water lakes and which is often referred to as an invasive species. The aim of our study was to analyze changes over time in the occurrence and distribution of blooms, and to find possible drivers of this change. We also performed spatial analyses to identify environmental factors c
First-line treatment of isolated resectable colorectal peritoneal metastases remains unclear. This study (the Swedish peritoneal study) compares cytoreductive surgery and intraperitoneal chemotherapy (surgery arm) with systemic chemotherapy (chemotherapy arm).
Routine monitoring of the quality of stroke care is becoming increasingly important since patient outcomes could be improved with better access to proven treatments. It remains unclear how many countries have established a national registry for monitoring stroke care.
We report on the design and operation of a novel sample stage, used to simultaneously measure X-ray scattering profiles and conductivity of a polymer electrolyte membrane (PEM) surrounded by humid air as a function of temperature and relative humidity. We present data obtained at the Advanced Light Source and Stanford Synchrotron Radiation Laboratory. We demonstrate precise humidity control and ac
Nonsuicidal self-injury (NSSI) in adolescents is a significant problem that needs to be addressed, and in some cases managed, in school settings. The current feasibility study uses screening questionnaires and follow up-interviews on NSSI in a community sample of adolescents (N ¼ 1,052) in Sweden. Both adolescents reporting self-injury (n ¼ 66) and a comparison group (n ¼ 31) were interviewed, and
Taking a global perspective this paper sets out to theoretically and empirically identify prosperity patterns for four groups of countries at different levels of economic development. It conceptualizes ‘prosperity’ in terms of ecological sustainability, social inclusion, and the quality of life and contextualizes this definition in global perspective. Subsequently, it operationalizes and measures
Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas((R)) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32muL) with high or intermediate a
The aim of this paper is to present an alternative method for the analysis of resistivity data. The methodology was developed during a study to evaluate if electrical resistivity can be used as a tool for analysing subsurface gas dynamics and gas emissions from landfills. The main assumption of this study was that variations in time of resistivity data correspond to variations in the relative amou
A method for screening of ketone biotransformations was developed and applied to the identification of Baeyer-Villiger monooxygenase (BVMO) activity. The method was based on the formation of a purple coloured product on reaction between an enolizable ketone and 3,5-dinitrobenzoic acid in an alkaline solution. Absorbance of the colour decreased with the size of the cycloketone ring. Stoichiometric
In this study, a coupled multi-species transport and chemical equilibrium model has been established. The model is capable of predicting time dependent variation of pore solution and solid-phase composition in concrete. Multi-species transport approaches, based on the Poisson–Nernst–Planck (PNP) theory alone, not involving chemical processes, have no real practical interest since the chemical acti
The locus encompassing the corticosteroidogenic genes CYP11B2 and CYP11B1 is of potential importance in essential hypertension. We analyzed the association of polymorphisms at this locus with risk of essential hypertension, using 2 white case-control collections for discovery (n = 3340) and confirmation (n = 2929). Single-marker and haplotype analyses were performed, with the CYP11B2 Intron 2 Conv
Abstract Aim: The Redesigning Daily Occupations programme (ReDO) is a Swedish work rehabilitation programme for women on sick leave due to stress-related disorders. The aim of the study was to investigate the participants' perceptions of taking part in the work rehabilitation programme. Methods: Seven of the 38 women who completed ReDO were interviewed during and after the programme. The interview
We investigate the full functional form of the first passage time density (FPTD) of a tracer particle in a single-file diffusion (SFD) system whose population is: (i) homogeneous, i.e., all particles having the same diffusion constant and (ii) heterogeneous, with diffusion constants drawn from a heavy-tailed power-law distribution. In parallel, the full FPTD for fractional Brownian motion [fBm-def
This paper presents a new strategy for steam pressure control during web breaks in the paper machine. The aim was to restart paper production with the same drying properties of the cylinder as before the break. A detailed physical dynamic model of the drying cylinder has been developed. The accuracy of the model has been verified through experiments made at the M-real paper mill in Husum, Sweden.
BACKGROUND: Adolescent smokers are often unsuccessful in quitting and difficult to retain in cessation programs. In health promotion, focusing on the right target groups is essential. Aim. The aim was to examine if adolescent occasional smokers differ from daily smokers, and if possible differences could be useful for targeted smoking cessation programs. METHODS: Ninety-one percent of all teenager
Occupational skin diseases are among the most frequent work-related diseases in industrialized countries. Good occupational skin disease statistics exist in few countries. Questionnaire studies are needed to get more data on the epidemiology of occupational skin diseases. The Nordic Occupational Skin Questionnaire Group has developed a new questionnaire tool - Nordic Occupational Skin Questionnair
This article stresses the significance of recognising interdependencies between factors determining disaster risk in any attempts to integrate disaster risk reduction in international development cooperation. It bases its arguments on the case studies of four past projects in Sri Lanka and Tajikistan, which are scrutinised using a theoretical framework based on systems approaches. It appears that
The relation between the atrioventricular conduction properties of the atrioventricular node and the anterograde conduction ability over the accessory pathway in the Wolff-Parkinson-White syndrome has never been studied. Atrioventricular nodal characteristics were studied in 285 patients with manifest and 204 with concealed accessory pathway who underwent radiofrequency ablation, and compared with
