Spectral analysis as well as parametric identification techniques have been applied to data from boiling water reactor noise measurements to estimate the process dynamics. Three different parametric model structures were tried. Least squares and maximum likelihood methods were tried to estimate the parameters of the models. Low order models were obtained in most cases.The results show the difficul

Rökare drabbas oftare av post­­operativa komplikationer än icke-rökare. Framför allt inom sår­läk­nings­­området är dokumentationen omfattande. Detta gäller även efter mindre rutiningrepp som bråckoperation eller ­appendektomi. De studier som undersökt snus har inte påvisat någon ökad risk för postoperativa komplikationer hos snusare. Intensivt rökstoppsprogram på 4–8 veckor inför operation medför

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:- To assess the effect of preoperative alcohol cessation interventions on the rate of postoperative complications in hazardous drinkers- To assess the effect of preoperative alcohol cessation interventions for hazardous drinkers on alcohol use in the postoperative period and longer term

Background: The aim of this study was to examine the effect of preoperative smoking cessation interventions on postoperative complications and smoking cessation itself. Methods: Relevant databases were searched for randomized controlled trials (RCTs) of preoperative smoking cessation interventions. Trial inclusion, risk of bias assessment and data extraction were performed by two authors. Risk rat

Smoking and hazardous drinking are common and important risk factors for an increased rate of complications after surgery. The underlying pathophysiological mechanisms include organic dysfunctions that can recover with abstinence. Abstinence starting 3-8 weeks before surgery will significantly reduce the incidence of several serious postoperative complications, such as wound and cardiopulmonary co

AIM: To describe how women smokers with newly diagnosed breast cancer experienced brief preoperative smoking cessation intervention in relation to breast cancer surgery. BACKGROUND: Preoperative smoking cessation intervention is relevant for short- and long-term risk reduction in newly diagnosed cancer patients. Our knowledge of how patients with malignant diagnoses experience preoperative smoking

The aim of this study was to compare long-term recurrence and death rates after a first episode of acute pancreatitis in patients with and without gallstones. Additionally, it was of interest to find out if there were factors predictive of readmission or death.

Patients who drink too much have more complications after surgery. The aim of this thesis was to evaluate the evidence, possible mechanisms, and prevention of the increased postoperative morbidity in alcohol abusers, defined by a consumption of at least five drinks per day. The literature could be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moder

A class of identification methods, proposed in [3], are based on the instrumental variable principle. This correspondence contains a continued analysis of convergence of the parameter estimates of these methods. Alternative, sufficient conditions for convergence to correct values are given. It is also shown by construction of counter-examples that the methods do not converge under general conditio

Evidence suggests that research benefits from diversity, yet science is concentrated to a small group of countries. Diversity in physical therapy research has so far not been studied thoroughly, and this is the first study to map physical therapy research geographically. The objective was to study the frequency and methodological quality of physical therapy-related randomized controlled trials (RC

Cities exhibit a rich and complex heterogeneity in people and activities. This poses a sizable challenge for planners when planning new neighbourhoods or the reconstruction of old ones as well as when considering the allocation of supply of and demand for amenities, e.g. kindergartens or health facilities. However, individual preferences may also exhibit common denominators that may provide struct

Importance: Prenatal exposure to phthalates has been associated with neurodevelopmental outcomes, but little is known about the association with language development. Objective: To examine the association of prenatal phthalate exposure with language development in children in 2 population-based pregnancy cohort studies. Design, Setting, and Participants: Data for this study were obtained from the

Inspired by Putnam’s study of Italy, this chapter develops applications that test the issue of social capital and health in the context of social epidemiology. Three central concepts are explained. The chapter attends to the technical issues, including, for example, the portion of children in subgroups identifying conflicts. The author then comes to his main message: the value of longitudinal expe

Paracetamol overdosing may cause liver injury including fulminant liver failure due to generation of the toxic metabolites, N-acetyl-p-benzoquinone imine (NAPQI) and p-benzoquinone (p-BQ). Herein, the chelating agent, N,N'-Bis(2-mercaptoethyl)isophthalamide (NBMI), was examined for its potential ability to entrap NAPQI and p-BQ and to prevent paracetamol-induced liver injury. Both NBMI and the con
