Objectives The study investigated the noise exposure in a group of Danish school teachers. The aims were to investigate if noise posed a risk of impairment of hearing and to study the association between classroom acoustical conditions, noise exposure, vocal symptoms, and cognitive fatigue. Methods Background noise levels, vocal load and speaking time were measured on 35 teachers during actual cla
Popular Abstract in Swedish När vi äter ökar nivån av blodsocker (blodglukos) i blodet. Glukos forslas i blodet till målvävnader, såsom fett och skelettmuskel, där det används som energi. Men för att glukos ska kunna tas upp av målvävnaden krävs insulin. Insulin är ett hormon som produceras av beta-celler i bukspottkörtelns Langerhanska öar, vars sekretion ut i blodet regleras av blodglukos. Då deType 2 diabetes (T2D) is a condition of high blood glucose levels due to insulin resistance and defective insulin secretion. Impaired insulin secretion plays a major role in the pathophysiology of T2D, it is mainly attributed to beta cell function i.e. failure to secrete insulin or reduced beta cell mass. The exocytotic process is crucial for beta cell function and its dysregulation leads to impai
In neurophysiology, investigating brain connectivity within and between different brain structures is of fundamental importance for understanding nervous system function and its relation to behavior. Yet, parallel recordings in multiple brain structures is highly challenging, especially in rodents, which are most commonly employed in neurophysiological research but rather small in size. In this st
In public international law, EU law, and national law there are numerous rules and principles stipulating the recognition of foreign administrative decisions. The article explores duties to recognise foreign administrative decisions, the possible limitations of such duties and the handling of cases involving recognition. Recognition of a foreign administrative decision means a form of transfer of
A single antenna based virtual antenna array at the receiver can be used to find direction of different incoming radio signals impinging at the receiver. In this paper, we investigate the performance of random 3D virtual antenna arrays for DoA estimation. We have computed a Cramer-Rao Lower Bound (CRLB) for DoA estimation if the true antenna positions are not known, but these are estimated with an
The azimuthal anisotropy coefficients v2 and v4 of p 0 and. mesons are measured in Au + Au collisions at root s(NN) = 200 GeV as a function of transverse momentum p(T) (1-14 GeV/c) and centrality. The extracted v(2) coefficients are found to be consistent between the two meson species over the measured p(T) range. The ratio of v(4)/v(2)(2) for pi(0) mesons is found to be independent of p(T) for 1-
In Kenya, the government is promoting high-value and drought resistant crop varieties in an effort to reduce poverty in rural areas. Sugar beet is one such crop. This study was conducted with two objectives: 1) to assess the opportunities and challenges for sugar beet cultivation and adoption in the Nyandarua district of Kenya and 2) to assess whether sugar beet adoption can offer an opportunity f
Background: Assessing left ventricular (LV) dysfunction by echocardiography in ICU patients is common. The aim of this study was to investigate mitral annular plane systolic excursion (MAPSE) in critically ill patients with shock and its relation to LV systolic and diastolic function, myocardial injury and to outcome. Methods: In a prospective, observational, cohort study we enrolled 50 patients w
Accurately reconstructing the rate of movement and extent of eolian dunes over thousands of years is a challenging endeavor. In this paper, we refine the methodology for utilizing lakes and bogs downwind of dune fields as precise recorders of past eolian activity. Sediment cores from two Allegan County lakes and one bog associated with dunes were studied to evaluate the importance of the various s
The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three-year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, 1992) - particularly Conscientiousness
The use of performance enhancing drugs, especially anabolic androgenic steroids (AAS) has emerged as a social problem outside competitive sports, linked to substance abuse and crime. The purpose of this article is to analyze the use of doping and attitudes to doping outside the competitive sports context in relation to age, gender, ethnicity, so¬cio-economic status, and branch of sport. The articl
Unlike many nanomaterials, nanocrystalline cellulose (CNC) is not synthesized from molecular or atomic components but rather extracted from naturally occurring cellulose. Undoubtedly, the exploitation of CNCs will become a bridge between nanoscience and natural resource products, which could play a major role in reviving the forest industry. In this work, CNC was successfully extracted from unusua
To assess HCV viremia levels just before, during and one year after anti-HCV seroconversion in people who inject drugs (PWID).
S100A8 and S100A9 are Ca(2+)-binding proteins that are associated with acute and chronic inflammation and cancer. They form predominantly heterodimers even if there are data supporting homodimer formation. We investigated the stability of the heterodimer in myeloid and S100A8/S100A9 over-expressing COS cells. In both cases, S100A8 and S100A9 proteins were not completely degraded even 48 hrs after
The main objective of this thesis was to quantitatively estimate the gaseous exchange of carbon dioxide (CO2) and methane (CH4) between a subarctic wetland ecosystem and the atmosphere. Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. The data presented were collecte
Popular Abstract in Swedish Vad triggar kunskapsprocesser och kunskapsstrategier i projektbaserade organisationer? Sofia Pemsel, Institutionen för Byggvetenskaper, Lunds Tekniska Högskola. Inledning Vad avgör om en organisation har välutvecklade och fungerande kunskapsprocesser och färdigheter eller inte? Varför är vissa organisationer fantastiska på kundhantering medans andra är fenomenala i teThe beauty of projects lies in their ability to integrate different knowledge bases and expertise in novel ways. Projects, though, are temporary in nature and this has consequences for the organization that uses them as a business strategy to improve its efficiency. Project-based organizations are representative of this organizational form and can either be standalone or subsidiary organizations w
Protein glycosylation has significant effects on the structure and function of proteins. The efficient separation and enrichment of glycoproteins from complex biological samples is one key aspect and represents a major bottleneck of glycoproteome research. In this paper, we have explored pH multimodal hydrophobic interaction chromatography to separate glycosylated from non-glycosylated forms of pr
