We compared the differences between spring and autumn in migration speed, fuelling rates and fuel loads of migrating Red Knots Calidris canutus. As a basis we used ringing data from Ottenby Bird Observatory, southeastern Sweden, collected 1948–2003, with morphometrical data from 1990–2003. Numbers ringed varied between 0 and 301 per year (average 56). Morphometrics, recoveries and recaptures of ri
Background/Aim: Viral respiratory infections are increasingly implicated in allergic exacerbations. Virus-induced activation of eosinophils through Toll-like receptors (TLRs) could be involved. The present study was designed to examine TLR3 expression in eosinophils from bone marrow (BM) and peripheral blood (PB) during symptomatic allergic rhinitis, and to evaluate the functional responsiveness o
Popular Abstract in Swedish Urininkontinens utgör ett stort socialt problem, framför allt hos den äldre befolkningen. Kliniskt är urininkontinens iakttaget i större omfattning hos kvinnor än hos män, men studier antyder männen är mer drabbade än vad nuvarande statistik gör gällande. Grundat på symptombild kan urininkontinens indelas i trängningsinkontinens, ansträngningsinkontinens samt överrinninNormal urine storage and bladder emptying are controlled by the central (CNS) as well as the peripheral nervous system. Dysfunction of these mechanisms can lead to urinary incontinence. Urinary tract dysfunctions have symptomatically been treated mainly with drugs acting peripherally. However, in the CNS, drug targets for pharmacological intervention may be found. The present study deals with effe
Popular Abstract in Swedish Olika sätt att mäta substrat (monosackarider) och produkter (främst etanol) vid tillverkning av biobränslet etanol har studerats. Etanoltillverkning sker i en fermentor med hjälp av mikroorganismer som kan omvandla socker. Det är av stort intresse att mäta koncentrationen av produkter och substrat under tillverkningsprocessens gång för att veta om den fortlöper som den Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. Carbon paste was used as the electrode material and served as the supporting matrix to incorporate the enzymes alcohol oxidase or pyranose oxidase. Hydrogen
Popular Abstract in English Proteins are molecular machines of the human body which regulate all life sustaining processes such as energy production, communication, transport of essential molecules, defense against microbes, etc. They are built by small molecular units called amino acids, bound together like pearls on a necklace. Each amino acid consists of a common part and a unique side chain. TAnisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. In this thesis, we have studied the effect of anisotropic interactions on the behavior of various proteins mainly
Purpose of this paper The outcome of product development, i.e. the product design, together with the packaging solution, has a great impact on the logistics performance of supply chains. Despite this, packaging has traditionally been given a very modest role in the product development literature as well as in the logistics literature. The aim of this paper is to show how logistics performance an
Two 8-year-old Pinus radiata trees growing in a dry-land plantation forest were subjected to a partial shading treatment for 2 years in order to investigate the responses of photosynthesis and tree growth to a long-term reduction in illuminated leaf area. The lower 60% of the crown of shaded trees was surrounded by 50% neutral density shade cloth. This reduced radiation absorption by 13% for the t
Popular Abstract in Swedish Zeoliter är en grupp av kisel-aluminium-föreningar, med karaktäristiska kanalsystem inuti strukturen, som har fått stor användning inom många områden inom teknik och vetenskap. Zeoliternas viktigaste användningsområden är som torkmedel, som molekylsiktar, som jonbytare och som katalysatorer. Användningen av naturligt förekommande zeoliter är relativt liten jämfört med aA highly dealuminated form of zeolite FAU, ultra-stable zeolite Y (USY), was used as an adsorbent matrix in the purification of proteins. Undesired proteins were removed from a crude preparation by adsorption on USY, increasing the purity of an unadsorbed protein (horse radish peroxidase), or the protein of interest was adsorbed on the zeolite and subsequently eluted through changes in the solutio
Popular Abstract in Swedish Betydelsen av tryckinducerad syrgastransport hos övervattensväxter Min avhandling handlar om vikten av att syrgas transporteras till rötter och rhizom hos övervattensväxter som bladvass, kaveldun och säv. Syrgas behövs för cellandningen i alla växtdelar, och i synnerhet i rötterna då de växer fort och har hög ämnesomsättning. Övervattensväxter har rötterna i vattendränThis thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. These phenotypic responses act to increase growth at specific water depths but may result in decreased tolerance to changed water depth. Oxygen nee
Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output.
Purpose: The purpose of this master thesis is
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are becoming an increasingly global concern. PFASs are highly fluorinated organic chemicals that represent a serious risk for environmental and human health. Due to their toxicological impact, PFASs are now included in several emission regulations. Even if the global level of PFASs use is decreasing much of present concentrations in the environ
Objective: Enhancing the reliability of myoelectric controllers that decode motor intent is a pressing challenge in the field of bionic prosthetics. State-of-the-art research has mostly focused on Supervised Learning (SL) techniques to tackle this problem. However, obtaining high-quality labeled data that accurately represents muscle activity during daily usage remains difficult. We investigate th
When natural areas are converted for human use, resulting changes in the landscape often lead to habitat loss and fragmentation, which can disrupt key ecological interactions such as pollination by animals. In this study, we investigated the independent effects of habitat loss and fragmentation on the structure and composition of plant-vertebrate pollinator interaction networks, focusing on intera
Background Childhood vaccination rates fluctuate over time and do not always meet the levels recommended by the WHO. Objective This study aims to provide an overview of measures countries have introduced to increase vaccination rates. Methods We developed a structured data collection template that was completed by country experts from Europe, Israel, the USA, and Canada. Experts were identified us
Papain-like protease (PLpro) of SARS-CoV-2 is a vital enzyme involved in viral polyprotein processing and in the suppression of host immune response. Due to its strategic role in viral replication and pathogenesis, PLpro represents a valid yet challenging target for drug development. Fragment-based drug discovery (FBDD) is a powerful strategy employed by the FragMAX facility at MAX IV to identify
Anthropogenic noise and artificial light at night (ALAN) are expanding globally, acting as pervasive sensory pollutants that can disrupt wildlife behaviour and reproduction. While most research has focused on diurnal species, the effects of these pollutants on the ecological response of nocturnal predators remain poorly understood. Using data from nine European countries, we investigated the effec
The aim of this study was to perform histopathological reassessment of primary resections of locally advanced colon cancer (CC) within a randomized controlled trial, with specific focus on surgical margins and synchronous locoregional peritoneal metastases (SL-PM), and to provide learning points for both surgeons and pathologists. All histopathological slides of patients with c/pT4N0-2M0 or perfor
