Background: Changes in the autonomic nervous system (ANS) tone are present before, during, and after episodes of atrial fibrillation (AF). Atrial fibrillatory rate (AFR, the inverse of the atrial cycle length) has been used as a surrogate marker for local refractoriness and is a key characteristic of the fibrillatory process in patients with AF. Aim of this study is to assess changes in AFR, as an

Helicobacter pylori is the most important cause of gastritis, peptic ulcers and the development of gastric cancer. The chronic active inflammation is dominated by neutrophils, macrophages, lymphocytes and plasma cells. Several interleukins (IL-8, IL-10 and IFN-gamma) are involved in the inflammatory process in the gastric mucosa. The aim of this study was to investigate the gastric inflammation in

Isolated exposures of basalt in a 1000 km 2 area in the central northern part of Skane have long been known to the local people. A volcanic origin for these rocks was finally resolved by geologists during the early 1800s. Until 1965 the volcanic activity was considered to have occurred during the Cenozoic i.e. not older than 65 Ma. In the 1970s attempts were made to directly date the volcanic acti

Ad hoc networks, being able to organize themselves without user intervention, can easily provide their users with mobility, multimedia support and group communication. However, they have to combine quality of service (QoS) and multicast routing strategies. This article defines the resource management and admission control components of the ad hoc QoS multicast (AQM) routing protocol, which achieve

We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; d=22 pc), based on new high-precision radial velocity (RV) observations from NIRPS and HARPS. With an orbital period of 2.85 d, the transiting sub-Neptune GJ 3090 b has a mass we refine to 4.52 ± 0.47 M>, which, combined with our derived radius of 2.18 ± 0.06 R2, yields a density of 2.40-0

The stability of therapeutic proteins is crucial for maintaining their efficacy and safety. Misfolded or aggregated proteins can accelerate aggregation by a seeding effect, altering protein stability and interactions. Heat-induced aggregates can pose a risk because they can have perturbed structures that expose aggregate-prone regions. This study explored seeding by heat-induced protein aggregates

Motivation is a hot topic in the corporate world and managers are searching for ways to motivate the workers in order to improve performance. Profit-seeking organizations are able to control the workers motivation and actions, because they are usually in higher power and employees are often dependent on the organization for monetary reasons (Sayer, 2007). But what about managers in voluntary organ

Leaching of dissolved organic carbon (DOC) from the forest floor and transport in soil solution into the mineral soil are important for carbon cycling in boreal forest ecosystems. We examined DOC concentrations in bulk deposition, throughfall and in soil solutions collected under the O and B horizons in three Norway spruce stands along a climatic gradient in Sweden. Mean annual temperature for the

This paper is part of a broader multilingual research project that addresses the relationships between affective phenomena (as units of personal experience), concepts (as units of cognitive processing) and the lexical items we use in talking about affective experience (as units of verbal communication. The focus will be here on data obtained in six Scandinavian and Romance languages (N=1093) with

Popular Abstract in Swedish Frisöryrket har en lång historia av stolta yrkesutövare, men frisörer arbetar i en komplex arbetsmiljö, där de utsätts för olika risker, inte bara luftvägsbesvär, utan även handeksem, muskelrelaterade besvär, stress, och ögonbesvär. I Sverige är 85 - 90 % av frisörerna kvinnor, varav de flesta är egenföretagare antingen som ensamägare till en salong eller tillsammans meLittle is known of respiratory symptoms in female hairdressers, and of the impact on the health-related quality of life (HRQoL), nor of knowledge of their own views on preventive work. The aim of this thesis was to examine the occurrence of asthma, symptoms and mechanism of bleaching-associated nasal symptoms, the effects on HRQoL and how young hairdressers reason about the work environment. A m

Purpose – Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region. Design/methodology/approach – The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, toge

Hypoxia, a growing worldwide problem, has been intermittently present in the modern Baltic Sea since its formation ca. 8000 cal. yr BP. However, both the spatial extent and intensity of hypoxia have increased with anthropogenic eutrophication due to nutrient inputs. Physical processes, which control stratification and the renewal of oxygen in bottom waters, are important constraints on the formati

Resulting from CSO critique of the Paris Declaration signatories of the Accra Agenda committed themselves to deepen CSO engagement in national aid effectiveness. Therefore the purpose herein is to increase understanding over functions, mechanisms, hindrances and opportunities facing CSO in this process in Tanzania. The primary method for achieving this was semi-structured interviews with 21 perso

Vid avtalsförhandlingar mellan privata näringsidkare kan det vara nödvändigt att utlämna hemlig information för att avtal ska kunna komma till stånd. Information och kunskap utgör ofta centrala tillgångar i ett företag och möjligheten att skydda sådana tillgångar i avtalsförhållanden kan vara av avgörande betydelse vid affärsuppgörelser. I detta avseende spelar sekretessavtal en viktig roll inom nIn contract negotiations between commercial parties, it may be necessary to disclose confidential information to establish a contractual relationship. Information and knowledge are often key assets of a business, and the ability to protect these assets may be crucial for the contracting parties. In this respect, confidentiality agreements play an important role in commercial relationships. In the

Investments in risk reduction are very complex with many factors that affect the overall profitability of the investment. Therefore, different models and approaches are used in the decision making process. An analysis of the problem is then made according to certain basic rules. When the risk situation is evaluated in this manner the decisions that are made are rational and consistent. By using th

Capacity development projects must be based on a thorough understanding of the situation within the subject country. However, the assessment phase is a very complex process and should cover a great number of aspects that both in time and space could affect the outcome of a triggering event. This project tries to identify what general aspects that could affect a country’s Disaster Management Capaci

Ever since 1987 the Lord’s Resistant Army (LRA), a theocratic rebel force, has been abducting children in Uganda to partake in the conflict against the Ugandan government and its forces. The children’s lives are drastically changed in a matter of minutes; they are suddenly forced to whiteness and take part in ruthless brutalities. Some of them live for months, others for years, under dictatorial r
