Aims Vegetation stimulates, in general, soil mineral weathering. It has been hypothesized that plant-associated microorganisms, especially ectomycorrhizal fungi play a major role in this process. We studied apatite dissolution in a vegetation gradient in southern Norway to test the role of ectomycorrhizal vegetation on mineral weathering. Methods A natural occurring lead contamination, probably pr
The purpose of this study was to evaluate the effect of prolonged heat processing (180 min at 50-80 degrees C) on the functional and theological properties of pectin, derived from olive mill wastewater (OMW). It was shown that a low temperature blanching of OMW at 60 degrees C, activates endogenous pectin methyl esterase and promotes demethylation, despite the high concentration of phenols. Activa
Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3
Integrated Processors (IP) are meant to supply algorithm-specific cores to a micro-electronic system. They are usually developed separately, and upon success turned into a part, that either by programming or by configuration can be re-used within many systems. This paper looks at architectures for Cellular Neural Networks (CNN) to become realized as IP. First current digital implementations are re
An evacuation experiment was performed in a road tunnel in order to investigate how motorists behave and emotionally respond when exposed to a fire emergency, how information and wayfinding systems are perceived and whether green flashing lights can influence exit choice. The participants believed that they were taking part in a study about driving behaviour. Approximately I kill inside the tunnel
Objective. To investigate alterations of tumor necrosis factor (TNF)-, interleukin (IL)-6, the Notch/Jagged signaling pathway, and hepatocyte proliferation, and their correlation in rats subjected to partial hepatectomy. Material and methods. Blood and liver tissues were sampled immediately (0), 5, 15, 30, 60, 180, 360, and 720 min, and 1, 2, 4, and 7 days after partial (70%) hepatectomy to measur
Building owners are encouraged to reduce energy use in order to both contribute to national energy-saving goals and reduce the costs of heating and operation. It is important to choose the most optimal renovation measures available so as to achieve cost-effective energy use while maintaining excellent indoor environments, without sacrificing architectural quality or negatively affecting the enviro
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
Photo-Fenton oxidation was used for treatment of synthetic textile wastewater as stand alone treatment, as pre-treatment before aerobic biological treatment and as post-treatment after anaerobic biological treatment. The processes were compared with regards to decolorization, chemical oxygen demand (COD) reduction and chemical consumption. When applying photo-Fenton alone for treatment of Remazol
Anestesiläkare rapporterades i en svensk studie ha en högre mortalitet än genomsnittet av läkare. Detta fynd har dock ej kunnat reproduceras i motsvarande studier i de övriga nordiska länderna. Likväl har det spekulerats i om den angivna överrisken bland svenska anestesiläkare kan relateras till gruppens jourarbete med höga krav, nattarbete och stress. Kunskapen om hälsoeffekter av läkares jourarb
The reaction kinetics of Candida antarctica lipase B (CalB) in the commercially available preparation Novozym (R) 435 (N435) were compared to those of preparations of CalB immobilised on Accurel (R) MP1000 (porous polypropylene). Two polypropylene preparations were made using enzyme loadings of 0.2% and 2% (w/w). All three preparations were used in hydrolysis as well as transesterification of two
The metabolic syndrome (MetS), characterized by obesity, hyperlipidemia, hypertension, and insulin resistance, is a growing epidemic worldwide, requiring new prevention strategies and therapeutics. The concept of prebiotics refers to selective stimulation of growth and/or activity(ies) of one or a limited number of microbial genus(era)/species in the gut microbiota that confer(s) health benefits t
A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T), the decay targeted is T -> Zt, while the decay targeted for a new charge -1/3 quark (B) is B -> Zb. The search is performed with a dataset corresponding to 20.3 fb(-1) of p p collisions at root s = 8TeV recorded in 2012 with t
Background: Patch testing has been used for more than 100 years as the best means to diagnose contact allergy. The increased use of the technique makes standardization of the methodology most important. Progress in the standardization of the patch test technique has been made through guidelines. Objectives: To investigate the intra-individual and inter-individual differences in reading of patch
We report the observation of Higgs boson decays to WW* based on an excess over background of 6.1 standard deviations in the dilepton final state, where the Standard Model expectation is 5.8 standard deviations. Evidence for the vector-boson fusion (VBF) production process is obtained with a significance of 3.2 standard deviations. The results are obtained from a data sample corresponding to an int
This paper explores the attitude-behaviour gap from an identity perspective in order to better understand why tourists act sustainably at "home" but not when "away". The majority of tourism-related CO2 emissions stems from transport. Behavioural change is a possible way to reduce those emissions. However, research indicates that instigating behavioural change within tourism is problematic, because
Purpose: The purpose of this thesis is to understand how Corporate Social Responsibility (CSR) as knowledge is anchored in an organization. The importance of this anchoring comes from the organizational need to adapt to the contextual global awareness related to CSR, amplified by the organizational transparency and exposure. Methodology: A hermeneutical approach has been taken in this thesis. We h
The purpose of this study was to bring forward knowledge about threats and violence in health and social-care working environments. Based on literature, I studied how the complex of threats and violence were described in research and reports, in order to find out which theories, solutions and attitudes were proposed. I also examined the extent, character, situations and consequences of threats and
