The aim of this report was to study possibilities of making the process of extracting lignin from black liquor at pulp and paper mills more efficient in the form of a literature study. Lignin is a commodity that is likely to become more valuable in the future due to work being done by a number of companies in utilizing it as for example a base for the production of renewable fuels and carbon fibre
I den aktuella studien undersöktes barns förmåga att med hjälp av verktyg använda tidigare kunskaper för att lösa en ny uppgift, genom en så kallad analog överföring. Uppgiften ställde krav barnets förmåga att bortse från vilseledande visuell information, till förmån för verktygets funktionalitet. 90 barn mellan 24 och 55 månader rekryterades från sju förskoleverksamheter i en svensk kommun. BarneChildren’s ability to access previous knowledge and use tools when solving a novel analogical task was examined. When confronted with the task, the children had to ignore misleading visual tool information and attend to its functionality. 90 children between 24 and 55 months from seven preschools were recruited. The study’s design was quasi-experimental and factorial, and the children were confron
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
Sweden has set a goal to produce 100% renewable electricity in 2040. In order to accomplish this, a transition towards renewable energy (RE) is necessary. However, the development of RE needs to coexist with other interests of the nation, as RE typically occupies large areas of land or off shore water. This has resulted in conflicts, for instance, between offshore wind power development and nation
In response to Loures Municipal Council’s recent proposal for redeveloping the Vila Valente Quarter of Moscavide, an area in urgent need of intervention, by demolishing, starting from scratch and relocating its vulnerable residents, this thesis challenges our responsibilities as architects when it comes to community development, especially with respect to the marginalised in society. We understand
Back in the mid 1900s, Zimbabwe was one of the most developed states in Africa with well-established infrastructure and a flourish economy thanks to inter alia agricultural exports and industries, among other things. A survey has been performed in order to evaluate the socio-economic conditions in Zimbabwe. This paper uses the fore mentioned study to investigate the challenges and problems that ca
Wetland Management Programme (WMP) inom Mekongsekretariatet har identifierat satellitbildsfjärranalys som ett viktigt verktyg för att undersöka Mekongflodens våtmarker (Petersen R., Petersen L. och Lacoursière 1990). Denna studie undersöker möjligheterna till storskalig markanvändningskartering av That Luang-Salakhamvåtmarken med omgivningar i västra Laos med hjälp av digitala fjärranalysmetoder oThe Wetland Management Programme (WMP) of the Mekong Secretariat has identified satellite remote sensing as being a valuable tool in conducting surveys of Mekong riperian wetlands (Petersen R., Petersen L. and Lacoursière 1990). This study involves evaluating the feasibility of large scale land use mapping of the That Luang-Salakham wetland and surroundings, Lao PDR, using digital satellite remote
In an economic environment signified by shortened product lifecycles, product proliferation and reduced profit margins, product replacement decision making (PRDM) ought to be an important part of management. The case is however often that considerably more energy and resources at a firm are spent at the opposite task, hence product development. The main purpose of this master thesis was to constru
Palmolja finns numer i en rad olika produkter, från margarin till biobränsle, och den globala efterfrågan på palmolja ökar år för år. I Malaysia har produktionen av palmolja ökat mer än 185 gånger sedan år 1961 och idag producerar landet omkring 40 % av världens palmolja. Den enorma tillväxten drivs av bland annat populationsökning, förändrade konsumtionsvanor samt policys som syftar till att öka There is a growing global demand for palm oil – a vegetable oil used in various products such as margarine and biofuel. Since 1961 the Malaysian palm oil production has experienced a 185-fold increase and currently Malaysia produces about 40 % of the world’s palm oil. Malaysia also has one of the world’s richest flora and fauna. The palm oil industry has gained much negative attention in recent ye
Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time. Afte
Syftet med denna masteruppsats är att implementera en tidigare modellerad kromatografisk adsorptionsprocess från MatLab till Modelon Impact, en simuleringsmjukvara. Modelon Im-pact använder sig av Modelica som syntax som i sin tur är användbart för skapandet av stora system av sammankopplade modeller som kan fungera i olika konfigurationer. Implemente-ringen är lyckad och gjord stegvis under projeThe aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. The model is successfully implemented and done in a step-
Introduction Both M. Supraspinatus and M. Infraspinatus of the rotator cuff play a role in stabilizing the shoulder during movement. When rehabilitating shoulders after injury a wide range of tools are used to strengthen the shoulder, often including a pulley system or TheraBand. According to evidence, no tool does however stand out as the most optimal one to use. Purpose The purpose of this study
The purpose of this study is to examine the ways in which health care counsellors in psychiatry for adults relate to the requirement of wearing white work clothes and how the white work clothes affect the psychosocial conversation. No previous research has been found on this matter in a Swedish context or for health care counsellors in particular. In this study, seven health care counsellors who w
This thesis explores the impact of community and individual shocks on children’s time use and aims to determine if and under what conditions households use child labor as a response to shocks. For this purpose, four survey rounds of a panel of Ethiopian children aged 5 to 15 are analysed. To address endogeneity problems and to overcome issues related to the data acquisition process, both a fixed e
Denna uppsats undersöker den historiska och juridiska utvecklingen av principen att domstolar ska beakta barns åsikter i vårdnadstvister i Sverige. Genom en rättshistorisk metod granskar studien utvecklingen av lagstiftningen från tidigt 1900-tal till nutid. Analysen identifierar centrala reformer som in-förde och stärkte kravet på att domstolar ska beakta barns åsikter och diskuterar anledningarnThis paper examines the historical and legal development of the principle that courts should consider children's opinions in custody disputes in Sweden. Using a legal-historical method, the study reviews the evolution of legislation from the early 20th century to the present day. The analysis identifies key reforms that introduced and strengthened the requirement for courts to take children
Global agri-food systems are in urgent need of a sustainability transformation guided by best practices of agroecology. The study used the Tool for Agroecological Performance Evaluation (TAPE) to assess the performance of seven market gardens in southern Sweden in comparison to the Swedish horticultural sector. The findings indicate that all participating market gardens could be considered agroeco
