Candelaria pacifica sp. nova (Ascomycota, Candelariales) and the identity of Candelaria vulgaris.

Candelaria pacifica is formally described. It is currently known from North and South America and Europe. The species is characterized by a small, lobate thallus with soredia formed on the lobe tips and along the margins. It has been confused with C. concolor in Europe and North America, but differs in having 8-spored asci and in lacking a lower cortex. Candelaria vulgaris, the type species of the

Characterization of Indigestible Carbohydrates in Various Fractions from Wheat Processing

Fractions rich in indigestible carbohydrates, such as fructan and arabinoxylan, are obtained as by-products when ethanol, starch, and gluten are produced from wheat flour. Today, these fractions are used as animal feed. However, these components may have positive physiological effects in humans. In this study, the content of indigestible carbohydrates in distillers' grains and process streams from

Fractionation of process water in thermomechanical pulp mills.

In this work process water from a thermomechanical pulp mill was divided into five fractions by filtration and membrane filtration. Suspended matter was mainly isolated in the retentate from the drum filter, extractives in the microfiltration retentate, hemicelluloses in the ultrafiltration retentate and lignin in the nanofiltration retentate. The final water fraction was of fresh water quality. F

MR for Quantitative Fat Imaging

An absolute measure of the fat content in various organs is an important part of diagnostics in obesity and diabetes. Fat quantification using MR-imaging is a non-invasive technique which provides both quantitative and spatial information on fat accumulation. However, for absolute quantification, it is necessary to address the various sources of contrast in MR-imaging. This paper summarizes basic

Flexible responses to visual and olfactory stimuli by foraging Manduca sexta: larval nutrition affects adult behaviour

Here, we show that the consequences of deficient micronutrient (beta-carotene) intake during larval stages of Manduca sexta are carried across metamorphosis, affecting adult behaviour. Our manipulation of larval diet allowed us to examine how developmental plasticity impacts the interplay between visual and olfactory inputs on adult foraging behaviour. Larvae of M. sexta were reared on natural (Ni

Comparing the folding free-energy landscapes of Abeta42 variants with different aggregation properties.

The properties of the amyloid-beta peptide that lead to aggregation associated with Alzheimer's disease are not fully understood. This study aims at identifying conformational differences among four variants of full-length Abeta42 that are known to display very different aggregation properties. By extensive all-atom Monte Carlo simulations, we find that a variety of beta-sheet structures with dist

Meteorological, agricultural and socioeconomic drought in the Duhok Governorate, Iraqi Kurdistan

Drought is a recurrent natural hazard that is expected to increase in the future due to anthropogenic climate change. The Middle East region witnessed a drought period between 2007 and 2009 that has been reported to have severe consequences for the population, especially in Syria and Iraq. This study seeks to assess the spatial and temporal characteristics of the drought in the Duhok Governorate i

Calcium Current Inactivation Rather than Pool Depletion Explains Reduced Exocytotic Rate with Prolonged Stimulation in Insulin-Secreting INS-1 832/13 Cells.

Impairment in beta-cell exocytosis is associated with reduced insulin secretion and diabetes. Here we aimed to investigate the dynamics of Ca2+-dependent insulin exocytosis with respect to pool depletion and Ca2+-current inactivation. We studied exocytosis, measured as increase in membrane capacitance (ΔCm), as a function of calcium entry (Q) in insulin secreting INS-1 832/13 cells using patch cla

Organizational change within medical research in Sweden: on the role of the individuals and institutions

The focus of this paper is on how organizational change within medical research evolves and is influenced by different types of institutions at different geographical levels, as well as what characteristics of the key individuals are important in enacting institutional opportunities and overcoming hindrances. The paper reveals the complexity of institutions influencing change processes. First, the

Spring initiation and autumn cessation of boreal coniferous forest CO2 exchange assessed by meteorological and biological variables

We studied the commencement and finishing of the growing season using different air temperature indices, the surface albedo, the chlorophyll fluorescence (Fv/Fm) and the carbon dioxide (CO2) tropospheric concentration, together with eddy covariance measurements of CO2 flux. We used CO2 flux data from four boreal coniferous forest sites covering a wide latitudinal range, and CO2 concentration measu

Formation of polar InN with surface Fermi level near the valence band maximum by means of ammonia nitridation

Development of InN films for devices is hindered due to metallic In clusters, formed readily during growth, and unintentional n-type conductivity of the nominally undoped films, including surface electron-accumulation layers via the Fermi level pinning into the conduction band. Plasma nitridation eliminates even large In clusters from the surface by changing them to two-dimensional InN [Yamaguchi

Powered mobility device use: participation and accessibility

Popular Abstract in Swedish Alla människor ska kunna vara delaktiga i samhället och mobilitet är viktigt för att kunna förflytta sig i bostaden och i samhället i stort. Mobilitet gör det möjligt att vara delaktig i olika aktiviteter som till exempel sociala aktiviteter och fritidsaktiviteter. Den åldrande befolkningen ökar och eftersom förflyttningssvårigheter ökar med stigande ålder, ökar även anThis thesis elucidates the use of powered mobility devices in a Swedish context. The overall aim was to increase and deepen the knowledge on powered mobility device use in relation to participation and accessibility in different environments and among different user groups, with a specific focus on independence and autonomy. An additional aim was to contribute to the knowledge base regarding the o

Comparative Study of Teaching Computational Mathematics in Two Different Learning Environments

Popular Abstract in Swedish I denna avhandling undersöker vi vilka anpassningar som behöver göras i designen av matematikkurser när de överförs från en kulturell miljö till en annan. Vi fokuserar på en kurs i beräkningsmatematik som undervisas på Lunds Universitet i Sverige och som vi under studien överförde till Sorans Universitet i Kurdistan/Irak. Projektet har två delar. Den första diskuterar hThis thesis aims to investigate necessary adaptations in the design of a mathematics course when it is transferred from one cultural environment to another. We focus on an elementary course in computational mathematics with Python taught at Lund University, Sweden, and at Soran University, Kurdistan/Iraq. This project holds two main parts. The first part elucidates how the necessary changes in tea

Christianity and Cormac McCarthy's The Road

Cormac McCarthy's The Road takes place not before or during but after the end. The novel follows a man and his son as they seek to survive in what remains of the world after some unspecified cataclysmic event. There is almost nothing left: no society, no food, no animals, no hope. Many readers will feel that the question the novel poses is why anyone would wish to continue living under such circum
