OBJECTIVES: This randomized case-control study compares teachers with self-reported voice problems to age-, gender-, and school-matched colleagues with self-reported voice health. The self-assessed voice function is related to factors known to influence the voice: laryngeal findings, voice quality, personality, psychosocial and coping aspects, searching for causative factors of voice problems in t

The active metabolite of vitamin D, 1,25-(OH)2D3, has immunomodulatory properties in addition to its more established action on bone and calcium metabolism. Recently vitamin D has been proposed as one of several environmental factors responsible for the increase in atopic diseases during the last decades. The objective of this study was to determine whether the estimated dose of dietary vitamin D3

Foragers increase their fitness by choosing the most profitable food source to forage on. Food resource is spatially distributed in a landscape context and, most importantly, in a patch scale. Therefore, they have to make daily decisions about where to forage based on their ecological information about the surrounding environment. There is a lack of descriptive studies on the relationship between

Implication of DNAJ co-chaperones in Neurodegenerative diseases General improvements of human life conditions at different levels translate into an increasingly growing life span expectancy of the earth population. This, however comes with the cost of an increase in neurodegenerative diseases which broadly increases in frequency with age. Most age related brain diseases such as Parkinson’s dis

This paper investigates whether the convention about wealth distribution in an M&A deal holds true for Acquirers of TMT-sector companies in Russia. The convention can be formulated as: In an M&A deal, bidders earn nothing, while targets enjoy wealth increase on average. The wealth effect on acquirers is measured by means of event study approach. The central tendencies of abnormal return an

Data-driven optimering en succé för skärande bearbetning Optimeringsmetod från maskininlärning mycket lovande vid användning för komplexa processer inom skärande bearbetning En otrolig mängd av industriell tillverkning idag förlitar sig på ett till synes enkelt koncept, att forma metall genom svarvning eller fräsning. Skärande bearbetning letar sin väg in i många industrier och alla sätt att ökThe purpose of this study was to investigate the applicability of data-driven experimental design for the optimization of a hard coating for cutting tools in metal machining. The complexity of metal machining leads to difficulty in theoretically modeling and understanding the interactions and correlations between parameters and performance. Because of this and the importance of incremental perform

Financial Innovation: cause or consequence? The recent financial crisis and subsequent investigation into to its causes leads many to propose that the primary suspect of instability is financial innovation itself. This paper introduces an alternative perspective that relates the perennially changing nature of financial innovation to the location of its emergence along the ‘technology shift’. Finan

In certain types of glulam roof structures with large spans, reliable methods for design with respect to instability are lacking. One example is a three-hinged roof truss with steel tension rods as shown in Figure 1. The types of structures shown in Figure 1 are investigated in the diploma project with the purpose to evaluate and improve the currently used design methods and detailing. Calculation

This study aims to explore the impact of capital structure on firm risk within China’s machinery industry, with a specific focus on the trade-off theory and equity financing preferences. Employing a quantitative methodology, the research analyzes financial data from 927 publicly listed machinery companies in China. Utilizing multiple linear regression models and statistical tests such as Pearson a

Objective To investigate the association between vaccinations in adults and the risk of developing rheumatoid arthritis (RA). Methods Data from the Swedish population-based Epidemiological Investigation of RA case-control study encompassing 1998 incident cases of RA aged 18-70 years and 2252 randomly selected controls matched for age, sex and residency were analysed. Those vaccinated within 5 year

Aim: According to the Cognitive Model of Insomnia, engaging in sleep-related cognitive processes may lead to sleep problems over time. The aim was to examine associations between five sleep-related cognitive processes and the incidence of insomnia, and to investigate if baseline anxiety and depression influence the associations. Methods: Two thousand three hundred and thirty-three participants com

Interaction forces between charged interfaces in the presence of oppositely charged dendrimers are studied by experiment and simulation. The experiments involve direct force measurements with all atomic force microscope (AFM) between two negatively charged colloidal particles in the presence of adsorbed, positively charged globular dendrimers. The simulations are carried out by treating the macroi

Long-term stability of endosseous implants depends on successful bone formation, ingrowth and adaptation to the implant. Specifically, it will define the mechanical properties of the newly formed bone-implant interface. 3D imaging during mechanical loading tests (in situ loading) can improve the understanding of the local processes leading to bone damage and failure. In this study, titanium screws

This paper examines the role of foreign trade in the consumption of energy in Czechoslovakia through a bottom-up approach in accounting for energy embodied in trade with manufactured goods. It provides a unique analysis of annual changes in energy embodied in trade in a country characterized by changing political regimes. On the whole, Czechoslovakia has been a net exporter of energy throughout th

Large-scale software development generates an ever-growing amount of information. Multiple research groups have proposed using approaches from the domain of information retrieval (IR) to recover traceability. Several enhancement strategies have been initially explored using the laboratory model of IR evaluation for performance assessment. We conducted a pilot experiment using printed candidate lis

In this paper we examine health among breast cancer 5-year survivors. We raise two questions: (1) how do the health level of this survival group compare to the health level of the general population; and (2) how have the health levels among these survivors changed over time. We found that 5-year breast cancer survivors assess their health lower than the general population, and that having being di

To clarify the role of metabolic factors in endometrial carcinogenesis, we conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), and examined the relation between prediagnostic plasma lipids, lipoproteins, and glucose, the metabolic syndrome (MetS; a cluster of metabolic factors) and endometrial cancer risk. Among pre- and postmenopau

Parkinson's disease is characterized by α-synuclein pathology in the form of Lewy bodies and Lewy neurites. Braak et al described the spatial and temporal spread of α-synuclein pathology in Parkinson's disease. Recent experimental studies have demonstrated that α-synuclein can transfer from cell to cell. In this review, we highlight the involvement of α-synuclein in Parkinson's disease and in Braa

The Leon-Chinandega plains are located in the north-western part of Nicaragua and represent the most important groundwater reservoir of the country. The aquifer is comprised of three hydrogeological units. The top unit is an unconfined alluvial and below a more consolidated volcanic aquifer is found. These aquifers rest on an ignimbrite unit that acts as the basement of the aquifer. The plains are
