Pulsed electric field (PEF) treatment is a non-thermal process which has a wide range of beneficial effects in food processing. The application of pulsed electric field treatment relevant for this work is as pre-treatment on basil leaves before the drying process. It has been proven that PEF treatment can significantly reduce the drying time due to the electroporation of the guard cells of stomata
Purpose: With this study, an attempt was made to present an in-depth analysis of and study the interaction between PR agencies and their client’s CSR strategies in order to illuminate the contributions of public relations to these, and also to review current CSR activities applied in Serbia. Furthermore, the purpose was to foster the role of PR as an agent for change regarding CSR strategies. R
PFOS (Perfluoroktansulfonat)-föroreningar har hittats på många ställen i Sverige och i resten av världen, därför finns det ett stort intresse och behov av att kunna kartlägga föroreningarna med fler metoder än vad som finns till-gängligt i dagsläget. Det här examensarbetet har som syfte att undersöka resistivitets- och IP (induced polarization)-mätningars lämplighet att kartlägga PFOS vid en brand
A normal mineral metabolism is integral for skeletal development and preservation of bone integrity. Fibroblast growth factor 23 (FGF-23) is a bone-derived circulating factor that decreases serum concentrations of inorganic phosphorous (P-i) and 1,25-dihydroxyvitamin D-3 [1,25(OH)(2)D-3]. Increased FGF-23 expression is a direct or indirect culprit in several skeletal disorders; however, the relati
In birds the major histocompatibility complex (MHC) organization differs both among and within orders; chickens Gallus gallus of the order Galliformes have a simple arrangement, while many songbirds of the order Passeriformes have a more complex arrangement with larger numbers of MHC class I and II genes. Chicken MHC genes are found at two independent loci, classical MHC-B and non-classical MHC-Y,
Objective: To examine the relationship of knee malalignment with occurrence of incident and enlarging bone marrow lesions (BMLs) and regression of BMLs. Methods: Subjects from the Multicenter Osteoarthritis Study aged 50-79 years with or at high risk of knee osteoarthritis were studied. Full-limb radiographs were taken at baseline and hip-knee-ankle mechanical axis was measured. Baseline and 30-mo
Background Plasma triglyceride levels are heritable and are correlated with the risk of coronary heart disease. Sequencing of the protein-coding regions of the human genome (the exome) has the potential to identify rare mutations that have a large effect on phenotype. Methods We sequenced the protein-coding regions of 18,666 genes in each of 3734 participants of European or African ancestry in the
Tidigare studier har dokumenterat ett flertal fossila meteoriter samt höga koncentrationer av utomjordisk kromit (ett järn-kromoxidmineral) i cirka 467 miljoner år gamla, mellanordoviciska sedimentlager. Fynden antas vara resultaten av ett tillfälligt förhöjt inflöde av meteoritiskt material, efter uppbrytningen av en kropp i asteroidbältet – de så kallade L-kondriternas föräldrakropp – för omkriNumerous fossil meteorites and high concentrations of sediment-dispersed extraterrestrial chromite (EC) grains with typical ordinary chondritic composition have previously been documented from 467±1.6 Ma Ma lower Kundan (Middle Ordovician) strata. These finds most likely reflect a temporarily enhanced influx of ordinary chon- dritic matter, following the disruption of the L chondrite parent body i
Populärvetenskaplig sammanfattning: Naturkatastrofer är något som Sverige är relativt förskonat från. Massrörelser, alltså markrörelser i jordtäcke eller berg såsom lerskred, slamströmmar och bergras, är däremot relativt vanligt förekommande runt om i landet. Det är dessutom så att frekvensen av den här typen av fenomen förväntas öka i Sverige till följd av framtida klimatförändringar. De områdenRecent studies indicate a widespread but largely overlooked hazard of contaminant mobilisation and transport in connection to mass movement activity into surface water systems in Sweden. Concerns are exacerbated by predicted effects of climate change, which suggest national increases in rates of precipitation, pore water pressures, run -off, erosion and mass movement occurrence. In this study, the
Degrowth is an academic concept and activists' niche project in Europe and other early-industrialized parts of the world aiming to reframe the current sustainability challenge of declining environmental and unjust social conditions. Its emphasis is on the radical transformation of the current societal-economic structure in order to achieve inherently sustainable conditions. There are various d
The expansion of Swedish wind energy grid has come at the cost of environmental, economic and social controversy, in which the issue of landscape quality change plays a prominent role. Tourism, an industry highly reliant on visual consumption of the landscape, is especially sensitive to this change. Scholars have repeatedly harvested evidences of a weak, but negative correlation between wind power
Background: The role of physical therapists are affected by several aspects including the therapeutic relationship, inter-professional relations, workloads, autonomy and their relations to everyday tasks. In particular, the latter of these is a topic of interest in regards to Japanese physical therapists since healthcare in Japan has shown tendencies toward the adoption of new technology. This, th
This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. The handheld nanoparticle detector Partec
To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. One such upgrading process is catalytic hydrodeoxygenation
Det har uttryckts oro över ungdomarnas ständiga uppkoppling via sociodigitala teknologier och hur detta kan relateras till en upplevd försämring av unga människors välbefinnande. Få studier har fokuserat på totala användningen av både sociala medier och dataspel; eller har utforskat potentiella positiva samband mellan sociodigitalt deltagande (SDP) och ungdomarnas välbefinnande. Syfte: Den aktuellConcern has been voiced about adolescents’ instant connectivity via socio-digital technologies and how that relates to a perceived worsening of young people’s well-being. Few studies have focused on cumulative use of both social media and gaming; and/or exploring potential positive associations of socio-digital participation (SDP) and adolescent well-being. Objectives: The current study aimed to
The main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated
The purpose of this report is to investigate and compare two potato chip production lines to determine the optimal layout of the factories in order to maximize the chips' adhesion ability to seasoning. The hypothesis of this study is that the adhesive ability of chips is highly dependent on how warm they are when they are seasoned, with warmer chips having a stronger adhesive ability. This hy
Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate t
Over the last decade the music festival sector grew enormously: in 2008 over a million festivalgoers gathered in the UK to share music and companionship. However in doing so musicfestivals generate large volumes of waste streams and consume large quantities of resources. Amusic festival of more than 40 000 people will produce in the order of 2000 tons of CO2e –with audience transportation and on s
