Verification of the cleaning routines in a nut roastery The purpose of this report is to verify if the cleaning routines used in a specific nut roastery give an adequate cleaning and make the products microbiologically safe. Furthermore, controls of the products have been made with regard to allergens, personal hygiene, cooling, water content, water activity and the level of oxygen left in the pac
Our intention with this essay was to examine how children were affected due to their parent’s substance abuse. Studies show that these children were particularly vulnerable and harmed throughout their upbringing because of their parents drinking problem. Our aim with our study was to gather further knowledge regarding people who grow up under these conditions and to better understand how it has af
There are several thousands of old landfills in Sweden and they are often located close to cities on valuable land, three of these landfills are Lassabacka in Varberg, Härlövsängar in Kristianstad and Onsjöparken in Eslöv. On these landfill methane- emission and concentration measurements are done with an IR Chamber called ULTRAMAT 23, a probe and the gas analyser LFG 20. This was done to see if t
The objective of this essay is to map the possible future scenarios of energy relations between the European Union (EU), the world’s biggest energy market, and Russia, the world’s largest producer. The security of energy supply is essential to the functioning of the EU. Energy security, therefore, is a highly politicized subject that has divided European capitals for decades and will, ceteris pari
New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. The physical traction limit set by the friction between the tires and the road
Much research on dolphin echolocation has focused on animals that have been trained to remain stationary or to carry a device that allows the animals to move but restricts the location of the sonar beam. In such cases, a small number of hydrophones measures sonar characteristics while dolphins solve echolocation tasks. As a result, much is known about the beam axis but relatively little is known a
The cost efficiency of the biorefining process can be improved by extracting high-molecular-mass hemicelluloses from lignocellulosic biomass prior to ethanol production. These hemicelluloses can be used in several high-value-added applications and are likely to be important raw materials in the future. In this study, steam pretreatment in an alkaline environment was used to pretreat the lignocellu
The equilibrium terrestrial biosphere model BIOME3 simulates vegetation distribution and biogeochemistry, and couples vegetation distribution directly to biogeochemistry. Model inputs consist of latitude, soil texture class, and monthly climate (temperature, precipitation, and sunshine) data on a 0.5 degrees grid. Ecophysiological constraints determine which plant functional types (PFTs) may poten
This paper argues that expected utility theory for actions in chancy environments should be formulated in terms of centered chances. The subjective expected utility of an option A may be seen as a weighted sum of the utilities of A in different possible worlds, with weights being the credences that the agent assigns to these worlds. The utility of A in a given world is then definable as a weighted
Abstract in UndeterminedCytomegalovirus (CMV) causes severe sequelae in congenitally infected newborns and may cause life-threatening disease in immuno-deficient patients. Recent findings demonstrate the possibility to alleviate the disease by infusing intravenous immunoglobulin G (IgG) preparations, indicating that antibodies are an effective therapeutic option. Modern molecular methodologies, li
Background. Fast and accurate work-up is crucial to ensure the best possible treatment and prognosis for patients with head and neck cancer. The presence or absence of neck lymph node metastases is important for the prognosis and the choice of treatment. Clinical lymph node (N)-staging is done by palpation and diagnostic imaging of the neck. We investigated the current practice of the initial radi
In many IBA applications the main aim is to obtain quantitative figures characterizing the sample. Normally charge, i.e. number of probe particles, is used for normalization and is measured either by collecting the charge deposited in the sample or by collecting the particle in a post-sample Faraday cup or in combination. Both these techniques have drawbacks and results can be difficult to compare
This study examines reproducibility of water and ethanol drop volumes from plastic squeeze dropper bottles, examines the difference in drop volumes between commonly used liquid patch test solutions, and evaluates the volumes of water and ethanol needed to saturate Finn and IQ Chamber filter papers. 2 plastic squeeze dropper bottles recommended for use in patch testing have poor reproducibility com
Aim. This paper is a report of a study to elucidate families' lived experience of diabetes one year after a child was diagnosed with type 1 diabetes. Background. The incidence of type 1 diabetes is rapidly increasing worldwide, with a shift towards younger age groups. This illness is treated by means of an intensive management regimen that often disrupts the child's usual activities and requires d
A search is presented for direct top-squark pair production in final states with two leptons (electrons or muons) of opposite charge using 20.3 fb(-1) of pp collision data at root s = 8 TeV, collected by the ATLAS experiment at the Large Hadron Collider in 2012. No excess over the Standard Model expectation is found. The results are interpreted under the separate assumptions (i) that the top squar
Biogenic volatile organic compounds (BVOCs) emitted by vegetation play an important role for aerosol mass loadings since the oxidation products of these compounds can take part in the formation and growth of secondary organic aerosols (SOA). The concentrations and properties of BVOCs and their oxidation products in the atmosphere are poorly characterized, which leads to high uncertainties in model
Popular Abstract in Swedish Björn Breidegards avhandling handlar om det specifika ingenjörskunnandets plats i rehabiliteringsteknisk forskning, både praktiskt, metodiskt och teoretiskt. För att de berörda människorna själva skall ha en reell möjlighet att resultatstyra behövs det en lyhördhet och att man kan prova sig fram. Detta kräver i sin tur ett top-down-orienterat arbete där varje del i det Based on the results of two rehabilitation engineering design projects, this thesis aims to present and analyze: ? What is required for genuine engineering knowledge and expertise to come into its own in rehabilitation engineering when the entire effort starts and ends with the person for whom it is intended. ? How the work of an engineer not only can improve the conditions for the actual d
The aim of this study was to investigate the correlations between epidemiological indices (objective) and self-perceived oral health (subjective) in adolescents at school level, and to study gender differences in epidemiological indices and in self-perceived oral health. The study comprised two sets of data from Skaraborg County, Sweden: 1. Self-reported questionnaires answered by adolescents at a
This thesis combines corpus-based, experimental and instrumental methods to investigate how professional speakers of English use prosody to signal important textual boundaries above the sentence level. In an initial study, prosodic features included in the transcriptions of the Spoken English Corpus, or readily derivable from these, are investigated. These include minor and major tone-unit length
This paper explores how the Engineering Design process might balance conflicting constraints of technical product design and the social demands of users. Building on a generic 2D map for innovation in design from the author’s previous work, a prototype 3D Diamond Model is presented to help structure conversations between Designers and Users – or indeed any other group with apparently opposing aims
