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
Introduction: Smoking is the most important risk factor for morbidity and mortality in hospital patients. Patient contact with the healthcare system should include smoking cessation counselling. Emergency admissions are seldom given this opportunity.Objective: The aim of the study was to illustrate the implementation of motivational counselling in a department of acute surgery.Methods: Between May
A new approach to the numerical solution of optimal control problems with state-variable inequality constraints is presented. It is shown that the concept of constraining hyperplanes may be used to approximate the original problem with a problem where the constraints are of a mixed state-control variable type. The efficiency and the accuracy of the combination of constraining hyperplanes and a sec
Least squares identification is considered from the Bayesian point of view. A necessary and sufficient condition for consistency almost everywhere is given under the assumption that the data are generated by a regression model with white and Ganssian noise.
Friction stir welding (FSW) is a solid-state welding process where metals are joined without melting. Heat is generated by friction between a rotating non-consumable tool and the work-piece material, and by mechanical deformation of the material. The process, invented in 1991, provides several benefits over arc welding and other fusion processes: No filler material has to be added, low energy cons
We develop a simulation method for Markov Jump processes with finite time steps based in a quasilinear approximation of the process and in multinomial random deviates. The second order approximation to the generating function, Error$=O(dt^{2})$, is developed in detailand an algorithm is presented. The algorithm is implemented for a Susceptible-Infected-Recovered-Susceptible (SIRS) epidemic model a
The convergence of a proposed method for state estimation in power systems is analysed for a case with constant state vector. In particular, a set into which estimates obtained by two versions of the SCI method converge is determined.
Constructing in rock will always involve unforeseen rock conditions. This involves a large risk to a project and can in the end entail delays and extra costs. To minimize the risks, an optimized pre-investigation program has to be conducted where essential information is gathered in order to make the best decisions throughout the construction project. In this work the main focus has been on the ap
In this paper we describe field investigations of leachate recirculation at a bioreactor landfill using geoelectrical imagining technique (i.e., electrical resistivity) combined with a tracer test. The use of geoelectrical imagining techniques is an established practice for environmental investigations and monitoring of various landfill processes and in recent years also the bioreactor landfill co
Notwithstanding its many successes since 1945, the project of European integration currently faces major difficulties, from financial crises and mass immigration to the impending departure of the UK from the European Union. At the same time, these challenges have spurred civil society organizations within and across Europe, revealing a shared public sphere in which citizens can mobilize around ref
The use of variable-length genomes in evolutionary computation has applications in optimisation when the size of the search space is unknown, and provides a unique environment to study the evolutionary dynamics of genome structure. Here, we revisit crossover for linear genomes of variable length, identifying two crucial attributes of successful recombination algorithms: the ability to retain homol
Millimeter-wave (mmWave) frequencies are set to play an important role in fifth-generation (5G) wireless systems. A pre-requisite for the design and performance assessment of 5G wireless is the understanding of the involved propagation processes and derivation of insightful channel models. Unlike bands below 6 GHz, several additional modelling features need to be catered for at mmWaves. For dynami
The demand for energy in the world is increasing steadily. As the standard of living for people in the developing countries is increasing so is the net energy use per capita. The main contributor to the energy consumption is the use of fossil fuels, which is also the major emission source for carbon dioxide. Carbon dioxide is in turn one of the most significant greenhouse gases and will enhance te
We develop the concept of evolving risk to demonstrate that the optimal policy choice between price and quantity instruments may change over time. Drawing from system innovation, evolutionary concepts and modern financial and transaction cost economics, we analyze dynamic cost and welfare impacts of instrument choice under uncertainty. In early market deployment of niche technologies, economic and
BACKGROUND: Pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD) is associated with increased morbidity and mortality. Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and decreased levels of amino acid precursors of nitric oxide (NO) have been associated with PH, but have not been studied in infants with PH secondary to BPD.OBJECTIVE: The aim of thi
Background: Faculty development roles are changing within organizations (Gibbs 2013). In previous research the expanding role in organizations as “Coming in from the margins” was described (Schroeder 2011). We studied how different levels of participation evolved within a research intense faculty with a complex organization and various educational programs.Summary of Work: The Centre was establish
In order to develop more sustainable district heating systems, the district heating sector is currently trying to increase the energy efficiency of these systems. One way of doing so is to identify customer installations in the systems that have poor cooling performance. This study aimed to develop an algorithm that was able to detect the poorly performing installations automatically using meter r
Reliable data on familial risks are important for clinical counselling and cancer genetics. However, the estimates of familial risk of gastric cancer vary widely. We examined the risk of familial gastric cancer using the updated Swedish Family-Cancer Database with 5358 patients among offspring and 36 486 patients among parents. There were 133 families with one parent and one offspring diagnosed wi
OBJECTIVE: Familial risks of depression have been assessed in small case-control studies, usually based on reported, but not medically verified depressions in family members; thus the degree of familial clustering for these diseases remains to be established.METHODS: We conducted a nationwide study on familial risks of depression linking the Multigeneration Register of 0-72-year-old individuals to
