In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was
Försörjningskedjan har stor potential till optimering. Många olika delar av kedjan kan optimeras och alla tänkbara förbättringar har inte testats än. Denna studien har sitt fokus på ruttoptimering, med det specifika målet att förstå hur maskininlärning kan användas inom ruttplanering, samt hur nyckelfaktorer som påverkar restiden för en rutt kan tas i åtanke för problemet. Tid lades på att studer
This study investigated the sustainable extraction of protein from field cress (Lepidium Cam-pestre) press cake, an underutilized by-product of oil extraction from a novel oilseed crop, which is currently being domesticated in Sweden. Field cress is recognized for its resilience in Nordic climates and its potential as a source of sustainable aviation fuel (SAF), yet the protein and fibre-rich cake
”As a thanks for the freedom we can now call ours”: the Swedish Youth Brigade (Švedska udarna brigada) in Yugoslavia in 1947. This paper examines the Swedish Youth Labour Brigade’s participation in the reconstruction work of post-war Yugoslavia in 1947, particularly their involvement on the Bosnian ”Youth Railway” (Omladinska pruga), linking Šamac with Sarajevo. With a microhistorical approach, th
Vad kostar det om ett exploateringsprojekt stöter på oförutsedda problem kopplade till naturvärden som man måste ta hänsyn till vid en markexploatering? Hur kan naturvärden egentligen påverka den ekonomiska kalkylen i ett projekt om de dyker upp som en överraskning under projektutvecklingen? Intressant är även att undersöka om det med träffsäkerhet går att identifiera, men också att prissätta och What is the cost if a development project encounters unforeseen difficulties related to values in nature that must be considered during a land development? How can natural values affect the balance sheet of a project if they appear as a surprise during project development? It is also interesting to investigate whether it is possible or not to identify and price risks related to nature in the proje
Hela livet är våra lungor livsviktiga organ. För nyfödda såväl som för äldre patienter så finns ett kliniskt behov av säker och kontinuerlig lungövervakning. Några av dagens vanliga metoder för att undersöka lungorna, såsom röntgen och datortomografi, ger endast en ögonblicksbild samt medför joniserande strålning. En ny teknik för klinisk lungmonitorering är nu på frammarch: GASMAS. GASMAS står föGAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. Because a similar need of lung monitoring exists in older patients, this work explores how GASMAS can be scaled up for larger geometries.
Luminiscensdatering är en väletablerad dateringsmetod inom geologisk och arkeologisk forskning. Dock är användandet av luminiscensdatering, mer specifikt optiskt stimulerad luminiscens (OSL), fortfarande underrepresenterat inom norsk arkeologi. Denna studie ämnar utreda lämpligheten av denna dateringsmetod som ett användbart alternativ för utgrävningar av Stenålderslokaler på den norska kusten. DeLuminescence dating is a well-established dating method within geological and archaeological research. However, the use of luminescence dating, and more specifically optically stimulated luminescence (OSL), is currently underutilised in Norwegian archaeology. This study set about determining the suitability of this dating method as a viable option for excavations of Norwegian coastal Stone Age sit
Det har länge varit känt att delar av läkares yrkesutövning är av sådan karaktär att den i objektiv mening uppfyller rekvisiten i vissa brottsbestämmelser. Eftersom sjukvården är en önskvärd verksamhet från samhällets sida finns det ett behov av en straffrättslig ansvarsfrihetsregel eller princip som motiverar tillåtligheten i läkares yrkesutövning. I denna uppsats undersöks läkares befogenheter o
Breast cancer is the most common type of cancer worldwide with an estimate of 2.3 million new cases in 2020, and the number one cause of cancer-related deaths in women. While survival rates are high in many high-income countries, with a five year relative survival rate of 85% and more, the respective survival rates are poor in many middle- and low-income countries, with rates as low as 12% in Kyad
Title: Critical Supply Chain Factors for Scaling a Startup -- A Case Study in the Industry of Semiconductors Author: Pontus Landgren Supervisors: Bertil Nilsson, Lund University, Faculty of Engineering & Lennart Moberg, Acconeer AB Background: A well implemented supply chain strategy aligned with the company's overall strategy is a prerequisite in order to successfully scale a startup.
Inflammatory bowel disease (IBD) is a global disease affecting more than 3.5 million people in the world, resulting in a high burden to societies. More research on IBD is definitely in need to prevent the disease and treat IBD patients. The intestinal epithelial barriers of IBD patients are weakened due to the inflammation, thereby, enteric microbes in the gut may translocate to the circulating sy
Information and Communications Technology is an increasing factor in the everyday life, whether this is private or public. In coherence with this, reports and research presents the contribution to effects in terms of pollution, such as greenhouse gas emissions and electronic waste. Current reports state that the agendas of enterprises, governments and societies increasingly include how to tackle e
