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

This bachelor thesis explores people’s awareness of Big data and algorithms in their everyday use of social media and search engines. This research aims to gain an understanding of what implications the awareness leads to, which effects on privacy issues and identity do they result in? Relating closely to privacy and identity is the question of surveillance and self-governance, both of which are f

Att bemöta konflikter och problemskapande beteende är en betydande del av personalens arbete i skolan. I denna studie fördjupas förståelsen för skolpersonals upplevelser av att bemöta detta. Semistrukturerade intervjuer genomfördes med sex anställda på resursskolor angående deras erfarenheter och upplevelser av strategier de använt sig av, om strategierna var verksamma och vad de behövde för att hManaging conflicts and challenging behaviors among pupils is a significant part of everyday work for school staff. This study broadens the comprehension of the experiences the school staff had from approaching these situations. Semi-structured interviews were conducted with six employees at resource schools on how they experienced the strategies they used, if the strategies seemed effective and wh

Med utgångspunkt från fem erkända svenska eller till svenska översatta biografier om Tjechov och några av hans noveller studeras på vilket sätt Tjechovs erfarenheter av att vara läkare och patient, sjuk i tuberkulos, har påverkat hans författarskap. Tjechovs attityd till den livsbegränsning och död, som hans tuberkulos innebar, var initialt förnekelse, men inte uppgivenhet och klagan. Den existen

Den globala uppvärmningen är ett av de största hot mot vår planet och mänsklighet idag. Elektriska fordon (EF) kan visa sig vara en stor hjälp för att bekämpa detta hot. Antagningsgraden av elektriska och elektroniska komponenter är dock fortfarande ganska långsam. Huvudmålet med denna avhandling är att designa en smartphoneapplikation med en användarcentrerad designprocess (ACD) som syftar till aGlobal warming is one of the biggest threats to our planet and humanity today. Electric vehicles (EV) can prove to be a great help in combating this threat. However, the adoption rate of EVs is still quite slow. The main goal of this thesis is to design a smartphone application using a human-centred design (HCD) process that aims to help people with switching to an EV. The project followed a clas

In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. One way to spatially separate users is through beamforming with sufficiently many antennas. In thi

Personalised nutrition is a concept which include dietary advice developed according to an individual’s needs and preferences. This by the usage of information regarding an individual’s lifestyle choices as well as of dietary, phenotypic and genotyping information. Scientists have had high expectations regarding personalised nutrition’s ability to optimise health and prevent and treat diseases. Ho

In the EU, climate policy-making takes place in a complex environment, where multiple climate and energy policy instruments co-exist and interact together. Interactions between different climate and energy instruments can affect - positively or negatively - the achievement of the climate targets. However, the performance of instruments is often evaluated without taking into account those interacti

Green energy defaults (where the uptake of renewable energy is promoted among households by opt-out tariffs) are gaining increasing interest with policy makers, due to the high enrolment rates shown in (experimental) studies. Such default choices are often justified on normative and behavioural grounds as although consumers express a desire and willingness to pay for green energy, they often fail

C-H activation with transition metal catalysts is one the most intense areas of research today and new advancements aid in the production of bulk chemicals, simplifying synthetic routes and transforming inert substrates into functionalized ones. By attempting to synthesize two N- heterocyclic palladium complexes (1 and 2, complex 3 is received) heterogenous, ligand- directed halogenation of substr

This thesis addresses the Science-Based Targets initiative (SBTi) in the context of two case studies on HEXPOL AB and Nolato AB. Findings suggest that companies with an advanced approach to sustainability usually have already implemented the SBTi. Therefore, for these companies, implementation of this initiative does not result in major internal or external changes. The interviews suggest that imp

Denna uppsats kommer studera prisspridningen på elbolagsmarknaden och syftet är att se om antalet elbolag påverkar prisspridningen. Enligt de sökkostnadsteorier som tas upp här kommer prisspridningen uppstå som ett resultat av att konsumenter har en positiv sökkostnad. Då sökkostnaden går mot noll borde priserna konvergera. Sökkostnadsteorier skiljer sig åt gällande effekten av ett ökat antal före

Purpose: The Catalyst TM is a non-ionizing and non-invasive optical scanning system that has attractive features for patient setup and monitoring, as well as for respiratory gating during, radiotherapy treatments. In this study, the conventional laser based setup was compared with the surface based setup by the CatalystTM. A new non-rigid algorithm was used taking the whole planning target volume 60 00 cancerfall rapporteras in varje år till socialstyrelsen men där numera fler än hälften botas. Detta eftersom vi blir skickligare inom området och nya behandlingstekniker utvecklas. Rektalcancer, även kallat ändtarmscancer är en cancerform som ökat under de senaste decennierna. Behandling av patienter med rektalcancer varierar beroende på var och i vilket stadie tumören befinner sig i. Oftast

Can there be causation between actual and non-actual states of affairs? To me it seems so, but few modal theories seem to be able to handle the question. I present and compare two theories of modality: David Lewis' modal realism and Alvin Plantinga's abstractionist theory of modality. None of the theories can give a perfect answer, but while Lewis' theory simply make such causal relati

This thesis evaluates the concept of characterization process of ultra-high vacuum system, known as SEA5 Serial Expansion Apparatus at RISE Research Institutes of Sweden. To produce precisely known pressures in the medium, high, and ultra-high vacuum range for gauge calibrations, the volume expansion system is often used for that purpose. There are different methods to determine the volume or the

Buildings that are built and the asphalt that is used for the paving needs to be tested to see if they fulfill certain requirements and standards. These types of tests are performed at Peab’s technology centers/laboratories and it is in one of their labs in Helsingborg that the degree project has been executed. As soon as the laboratory gets a concrete sample, they are supposed to register it in t

The passing of Thailand’s King Bhumibol Adulyadej on October 13, 2016 marked a significant turning point in modern Thai history. As the world’s longest-reigning monarch, King Bhumibol had been much loved and revered as the country’s father figure for 70 years. In the wake of his demise, it seemed to be that every corner of Thailand was packed with emotions that also came with an array of cultural

It is important to examine parent advocacy programs to understand how they function in a society where there are many structural obstacles to those with little power. These programs can provide an impactful way to level out power imbalances. This case study examined through a lens of legal consciousness theory, power and empowerment theory, and the four capitals as developed by Bourdieu, the pur
