In 1964, a theory was presented on how an invisible field is acting in nature, which causes mass to arise. The theory gives an explanation of how something can come from nothing and thus takes humanity one step closer to understanding how the universe works. Proving the theory was problematized by the fact that no experiments could be conducted since particle accelerators at the time weren't p

Metacognition is necessary for learning. Without know-ing what you know, what you don’t know and what you are about to learn, seeking new knowledge becomes both hard and inefficient. At the same time, keeping old facts (as well as old skills) in mind at a meta-level when striv-ing for new insights is not always an easy task. Conse-quently, external visible cues and representations are essential, r

Översvämningar och vattenföroreningar är kopplade till försummelse av vattenhantering vid hastig urban utveckling. Om tre decennier förväntas 66% av jordens befolkning bo i städer. Hur löser vi detta? Idag bor nästan hälften av jordens befolkning i städer – en siffra som förväntas öka till mer än fem miljarder personer fram till 2030. Urbanisering anses ha stor positiv påverkan på ekonomisk tillvDue to internal conflicts and an economical conversion in the mid 1900’s, the Colombian society has seen a great social transition from rural to urbanised in the last 50 years. Apart from positive impacts of urbanisation on social factors, there are hydrological issues coupled to it. With the aim to assess the impact of urbanisation on runoff peak flows in Bogota, the historical change in impervio

Tidigare studier indikerar att ooider har förutsättningar att användas som naturliga arkiv för att undersöka variationer i oceankemin samt klimatförändringar som sträcker sig hundratals år tillbaks. Ooider är sfäriska eller ellipsoidformade karbonatkorn med en medelstorlek mellan 0.25 och 2 millimeter. Ooidens struktur kan variera, men gemensamt för dem är att de utgörs av en kärna som kan vara en

Bakgrund: På grund av den höga invandringen av immigranter till Sverige från Mellanöstern och Västasien har antalet migrerade kvinnor blivit allt flera. Kvinnor som både lider av fysiska och psykiska funktionsnedsättningar har ofta svårt att anpassa sig till den nya kulturen där kulturella värderingar skapar problem i vardagen. Idag finns det ganska få studier som handlar om första-generationens i

Background: Colorectal cancer constitutes a major malignancy and the fourth major cause of deaths associated with cancer. Chronic inflammatory bowel diseases like Crohn´s disease and ulcerative colitis are one of the risk factors for the development of CRC. Cysteinyl leukotrienes (CysLTs) regulate both acute and chronic inflammation through lipophilic signaling. Upregulation of the expression of C

Today, one of the main economic engines is construction field. A few periods of history showed that in Lithuania, the main goal for the companies were to build fast, cheap dwellings on the empty lots. The capital of Lithuania, Vilnius city is not an exception. City is built ineffectively. Functions, neighbourhoods are far apart from each other and the transportation ineffectiveness leads to the lo

The Differentiated Services (DiffServ) Architecture, a Quality of Service (QoS) solution being worked on by an IETF work group, is aimed to solve the increasing problems with no service guarantees in the current Internet. New services such as video-on-demand and IP-telephony will be unusable without some sort of service guarantees on which to build applications on. A replacement architecture for t

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
