Wireless sensor networks are composed of a large number of sensor nodes with limited energy resources. Once deployed, the sensor nodes are usually inaccessible to the user, and thus replacement of the energy resource is not feasible. Hence, energy efficiency is a key design issue that needs to be enhanced in order to improve the life span of the entire network. Several routing protocols have been
A random amplified polymorphic DNA (RAPD) protocol was developed for interlaboratory use to discriminate food-borne Yersinia enterocolitica O:3 from other serogroups of Y. enterocolitica and from Y. enterocolitica-like species. Factors that were studied regarding the RAPD performance were choice of primers and concentration of PCR reagents (template DNA, MgCl2, primer and Taq DNA polymerase). A fa
Homogeneous charge compression ignition (HCCI) is a hybrid of the sparkignition and compression ignition engine concepts. As in a sparkignition engine, a homogeneous fuel-air mixture is created in theinlet system. During the compression stroke the temperature of themixture increases and reaches the point of auto ignition, just as in acompression ignition engine (or Diesel). One challenge with HCCI
Background and purpose: To evaluate the efficacy and safety of boron neutron capture therapy (BNCT) for glioblastoma multiforme (GBM) using a novel protocol for the boronophenylalanine-fructose (BPA-F) infusion. Patient and methods: This phase II study included 30 patients, 26-69 years old, with a good performance status of which 27 have undergone debulking surgery. BPA-F (900 mg BPA/kg body weigh
Recent experimental evidence indicates that neurotrophic factors play a role in the pathophysiology of epilepsy. The objective of this study was to explore whether signaling through one of the glial cell line-derived neurotrophic factor family receptors, GFRα2, influences the severity of kindling-evoked, rapidly recurring seizures and the subsequent development of permanent hyperexcitability. We a
Purpose– The purpose of this paper is to offer a framework for the analysis and evaluation of city brands equity that is firmly anchored to the interdisciplinary characteristics of the city branding research domain.Design/methodology/approach– The study builds upon a database of 217 articles dealing with the phenomena of city branding retrieved from Lucarelli and Berg.Findings– City brands are und
Background: Lipoprotein(a) concentrations in plasma are associated with cardiovascular risk in the general population. Whether lipoprotein(a) concentrations or LPA genetic variants predict long-term mortality in patients with established coronary heart disease remains less clear. Methods: We obtained data from 3313 patients with established coronary heart disease in the Ludwigshafen Risk and Cardi
Metal nanoclusters, supported on inert substrates, exhibiting well-defined shapes and sizes in a broad range of temperatures are a major object of desire in nanotechnology. Here, a technique is presented that improves the thermal stability of monodisperse and crystalline transition metal nanoclusters grown in a regular array on metal-supported graphene. To stabilize the clusters after growth under
Fuel cells in combination with hydrogen are expected to play an important role in a future, sustainable transport system. Recent studies have provided insight into how technological transitions may come about and may be I managed. However, there is a lack of methodologies aimed at starting off transitions or system innovations, in practice. This paper addresses this issue by presenting a methodolo
The thesis examines the truth and reconciliation commission in South Africa and its possibilities to act as a vehicle in the process of consolidating democracy. The norms and values that can be found in the principles and practices of the commission are scrutinized, and the means of presenting this norms to the public is also looked into. The issue of how to deal with the human rights violations o
Vårt syfte är genom jämförelse mellan två olika perspektiv och användningar av begreppet dualism hitta metoder för att inte begränsa strategibildning till valsituationer utan möjliggöra sätt att hantera motsatser och poler som komplement. Tanken är att ge undersökningen en utvecklande ansats. Därför valde vi att fokusera på ett fallföretag som aktivt strävade efter två mål. Intervjuer har gjorts p
The aim of our study was to examine how concepts of motherhood and fatherhood interact with other determining factors in child custody investigations. Emanating from our own work experience in social work, we began to consider the prevalent values surrounding parenting, in particular, those terms related to motherhood and fatherhood. Thus our central issues of examination are which assessment crit
In electromyographic (EMG) and functional magnetic resonance imaging (fMRI) studies, muscle and brain activity was compared during low levels of tooth clenching using a novel biting device to control bite force. A total of 21 healthy subjects performed motor tasks, comprising tooth clenching at 5, 10 and 20N. During all measurements, subjects kept the novel bite device between the anterior teeth d
Background: Food consumption is one of the most important drivers of environmental pressures. Adoption of healthy diets is suggested to be an option for less environmentally intensive food habits and improved public health. In particular, changes in meat consumption are believed to bring potential benefits. Objective: To quantify the impact of changes in meat consumption on the dietary contributio
The Boston Psychiatric Rehabilitation (BPR) approach is individualized and characterized by being based entirely on the individual's unique needs and preferences in the areas of working, learning, social contacts, and living environment. Relatives of clients in mental health services influence the client's possibilities for recovery by their everyday relationship. Relatives have, however, traditio
