Sugarcane bagasse was subjected to steam pretreatment impregnated with hydrogen peroxide. Analyses were performed using 2(3) factorial designs and enzymatic hydrolysis was performed at two different solid concentrations and with washed and unwashed material to evaluate the importance of this step for obtaining high cellulose conversion. Similar cellulose conversion were obtained at different condi

The common cold may affect an individual's life, or socio-economic development. This study investigated the effect of a probiotic product (mixed strains) on colds and changes in the oral microbiome. The study included 45 subjects, 23 taking the probiotic product (probiotic groups) and 22 taking the placebo (placebo-control group). The number of colds and duration of colds were investigated sep

High-Level Synthesis(HLS) is a design methodology that enables designers to implement hardware from high-level coding languages, such as C, C++, or System C. It provides designers with the ability to convey their design at a higher level of abstraction, which allows more emphasis on an algorithm and functional aspects of design instead on low-level hardware details. As precise control of signal ti

Elförsörjningen som till huvuddel kommer från fossila bränslen uppfyller vanligen inte efterfrågan i Irak. Samtidigt som det finns goda förutsättningar och stor potential för att installera och utnyttja solel som en lösning för den bristande elförsörjningen men med omtanke som värnar om miljön. Idag har cirka 20 procent av den irakiska befolkningen ingen tillgång till el, de återstående 80 procentThe main supply of electricity from fossil fuels does not usually meet demand in Iraq. At the same time, there are good conditions and great potential for installing and utilizing environmental friendly electricity from solar energy as a solution to the lack of power supply. Today, about 20 percent of the Iraqi population has no access to electricity, the remaining 80 percent have no continuous el

Authors: Jessica Bjurberg & Anna Engblom Title: Social Worker – the helping hand A qualitative study how active social workers experience their professional identity. Supervisor: Mikael Sandgren Assesor: Janicke Andersson The purpose of our study was to investigate how active social workers experience their professional identity. The method used for this investigation was semi-structured

During this thesis I have used a methodology called MIFO ‘Metodik för Inventering av Förorenade Områden’ (english: Method of Surveying Contaminated Sites), to investigate the contamination situation on a property plot in the municipality of Eslöv, Sweden where a former trading garden was active during the late thirties to the early eighties. A contaminated site is a site where the levels of a cont

In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. The DPAs are designed using AWR design environment with virtual source (VS) models of In(Ga)As nanowire transistors and 50 nm gate length. Th

Den bästa teorin vi har om den subatomära världen kallas för ”Standardmodellen”. Standardmodellen beskriver de allra minsta partiklarna och deras interaktioner med varandra genom den elektromagnetiska svaga och starka kraften. Genom åren har Standardmodellen förutspått en rad av olika partiklar som har verifierats experimentellt. År 2012 upptäcktes den allra sista partikeln förutspådd av standardmIn this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. This leads to one scalar field mixing with the SM-like Higgs field and one stable scalar singlet. Thus, three scalar bosons

Millimeter wave pulsed radar has found many applications, among them hand gesture sensing, which this work has as purpose. This application has already shown good potential, [1], and here in this work robustness aspects are taken into account. A classification task was defined, where distinction should be made between five different small hand gestures, recorded by 18 people in total. The classifi

Priming effects have gotten revived interest in the last decade due to the concerns of global warming. Priming are defined as an increase in decomposition of soil organic matter due to the addition of organic or mineral substances. The worldwide used herbicide glyphosate is rapidly degraded by microorganisms. Hence, it might give rise to priming effects in soils. This was tested by adding glyphosa

Föreliggande uppsats är ett examensarbete i juris kandidatprogrammet. Uppsatsen är skriven inom området familjerätt, mer preciserat inom successionsrätten. Uppsatsen behandlar efterlevande makes arvsrätt genom att gå igenom de regler som finns på området i Sverige, Norge och Danmark. Inom arvsrätten har det länge varit släktskapet som styrt vart arvet efter en avliden skall hamna. I dagens samhäThis thesis is written in the field of family law, more precisely about the law of succession. The thesis describes the spouse’s right to inheritance by comparing the rules in Sweden, Norway and Denmark. In the Swedish law of succession, it has long been the kinship that controlled where the estate of a deceased person should end up. The legislature has to some extent moved away from this. It is

Since 2010 and the enactment of the primary care reform, accredited private providers have been allowed unrestricted establishment in Sweden. Today, this means that a large share of primary care in Sweden is provided by large corporations. However, despite the important role that primary care plays, research into how private ownership affects the care that is provided is very limited. Drawing from

This qualitative study aims to investigate the meaning of the smartphone for young people as well as the way young people experience their parents and the staff at schools relating to them using their smartphones. It also investigates young peoples thoughts about restrictions made by their parents and the staff at school and if or in what ways the restrictions may affect the relationship between a

This study aimed to research the phenomenon of contact tracing of sexually transmitted infections through the perspective of healthcare social workers. The research questions were what competencies could contribute to a satisfactory contact tracing and whether these competencies corresponded to those the health care social worker typically has. This was researched using a qualitative research meth

Very sick patients who need specialized health services often require transport from their community to a regional facility that is appropriately resourced to provide definitive care for their condition. This is particularly important for people living in rural and remote areas but can be challenging due to long distances, mountainous terrain and inclement weather. The purpose of this research wa

Att separera två eller flera inspelade ljudsignaler är generellt ett svårlöst problem, men det blir enklare att lösa desto mer signalerna skiljer sig från varandra. Genom att använda en parabolformad reflektor går det att skapa skillnader mellan signalerna på ett sådant sätt att signalseparationen kan förbättras.This master’s thesis studies the use of physical structures for signal source separation. A parabolic reflector was used to alter the directional properties of one microphone in a two-microphone array. A method to estimate the mixing channels from measured data is presented, as well as a method to find the optimal separating channels. Measurements of the directional properties and mixing channels

Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. However, quantitative relationships between barrier and inland production well have not been re

Amfibier i dagvattendammar — vad vet vi? Bor du i en stad men har hört grodor kväka under sommarmånaderna? Då är det inte osannolikt att de satt och ropade på varandra i en dagvattendamm. Amfibier brukar kanske inte alltid förknippas med stadsnära miljöer, men förutom att bidra med vattenrening och flödesutjämning, så kan dagvattendammar agera nattklubb och barnkammare. (För att inte tala om inseAmid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
