Methane production from llama and cow manures from the Bolivian high plateau (The "Altiplano") was studied using a parallel reactor set-up consisting of 10 lab-scale biogasifiers. The effects of pressure (495 and 760 mmHg), temperature (11 and 35 degrees C), hydraulic retention time (20 and 50 days), and manure content in the slurry (10%, 20% and 50%) were evaluated with respect to productivity an
De flesta skattesystem beaktar skattebetalares skatteförmåga, främst genom olika avdrag. När en individ får inkomster från ett land men bor i ett annat uppkommer frågan vilket land som ska ta hänsyn till skatteförmågan. Det traditionella svaret, hemviststaten, har förändrats något genom EU-rätten, som innebär att källstaten i vissa fall måste beakta skatteförmågan hos individer som är bosatta utom
The extracellular buildup of amyloid beta (Aβ) plaques in the brain is a hallmark of Alzheimer's disease (AD). Detection of Aβ pathology is essential for AD diagnosis and for identifying and recruiting research participants for clinical trials evaluating disease-modifying therapies. Currently, AD diagnoses are usually made by clinical assessments, although detection of AD pathology with positron e
Tradera, Sveriges ledande marknadsplats för cirkulär konsumtion på nätet, överväger att gå in på marknaden för bilannonsering på nätet i Sverige som en ny vertikal marknad för att diversifiera sin verksamhet. Detta examensarbete syftar till att avgöra om Tradera bör gå in på marknaden för bilannonsering online och att föreslå en strategisk plan för inträdet om det bedöms vara fördelaktigt. ProjekTradera, Sweden's leading online marketplace for circular consumption, is considering entering the online automotive advertising market in Sweden as a new vertical to diversify its business. This thesis aims to determine if Tradera should enter the online automotive advertising market and to propose a strategic roadmap for entry if it is determined to be beneficial. The scope of this project
In recent years, microwave applications in the food products have attracted increasing attention by the food packaging industry and the consumers due to their convenience, low energy and water usage and short processing time giving them a sustainable advantage over competing technologies. In-pack pasteurization represents one of the fastest developing technologies in preparing and delivering safe
Atomic-scale understanding and processing of the oxidation of III-V compound-semiconductor surfaces are essential for developing materials for various devices (e.g., transistors, solar cells, and light emitting diodes). The oxidation-induced defect-rich phases at the interfaces of oxide/III-V junctions significantly affect the electrical performance of devices. In this study, a method to control t
Background: Epidemiological studies have shown considerable heritability of blood pressure, thus suggesting a role for genetic factors. Previous studies have shown an association of a single nucleotide polymorphism rs5068 in the NPPA locus gene with higher levels of circulating atrial natriuretic peptide as well as with lower intra individual blood pressure, but up to date, no association between
The modernisation of Swedish households during the twentieth century prompted a considerable productivity growth in household production. This paper examines the association between this process and the allocation of female time in Swedish urban households during the period 1920-1990. Estimates presented in the paper suggest a minimum potential time reduction for a fixed volume of routine househol
Popular Abstract in Swedish Små, trådlösa och portabla apparater utgör idag en stor del av vår uppkopplade värld. Under det senaste decenniet har dock flera teknologiska framsteg lett mot en utveckling där allt från maskiner till kläder kommunicerar med varandra. Detta brukar kallas för "sakernas internet" och uppskattas involvera 50 miljarder enheter år 2020. Genom att förse dessa enheter med småThe modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuous-time Delta-Sigma mod
