The electrochemical capacity of the nickel mass in the positive electrode when subjected to various conditions, and the relation to changes in the nickel hydroxide phases and crystallite size was studied in this thesis work. The various conditions being: two different electrolytes, KOH and KOH/LiOH, different temperature during charging and different charge times. The nickel mass was made into mon
This project is a collaboration with Electrolux, KTH Royal Institute of Technology and the School of Industrial Design (Lund University). The goal of the project was to investigate new ways of cooling an individual, to ultimately result in a product proposal. We have all experienced heat waves in the summer, which can affect us even in our homes. In addition, typical home activities such as cleani
Arbetet fokuserar på att ge en tydlig bakgrund till vad dagens projektingenjörer har för uppgift i ett ledande projekt. En frågeställning genom arbetet kommer att vara jämförelse mellan Trafikverkets definition av projektingenjörer kontra konsultens definition av projektingenjörer. Upplever projekteringsorganisationerna de krav som ställs på projektingenjörerna? Finns det en tydlig skillnad på kon
Denna studie fokuserar på en nästan 1700 år lång sjösedimentsekvens från Hässeldala Port i centrala Blekinge, sydöstra Sverige. Den omfattar övergångsperioden mellan pleistocen och holocen, eller mer precist eventen GI-1a och GS-1 samt början av den holocena epoken i iskärnorna, vilket motsvarar de sydsvenska pollenzonerna sen allerød till tidig preboreal. För att studera den senglaciala klimatutv
Water stress assessments on basin level of 96 SCA sites and global water issues affecting industry are presented. Four tools are evaluated with the aim to find indices that measure water stress, i.e. lack of water of good enough quality for humans and the ecosystem. Water indices, developed through research, become more accessible when they are in water tools, developed by non-governmental organis
This essay has translation of the Bible in view and more specifically inclusive language. I study a new test translation of Galatians, commissioned by the Swedish Bible Society this year. This translation has applied inclusive language and my problem for this essay is: is the Swedish Bible Society ́s test translation of the Galatians a plausible application of inclusive language? To be able to ans
This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. The methodology is an action research study with information gathered from a literature study and survey. Six different risk analysis methods hav
Biomanipulation, i.e. to reduced planktivorous- and benthivorous fish in order to receive changes in the trophic structure has been a successful method to improve water quality and the ecological status in eutrophic lakes. The initial idea was to increase the abundance of large zooplankton and thus to cause a trophic cascade with reduced algal biomass. Many studies failed to observe an increase of
The number of companies in Sweden has shown a significant increase over the last five years (www.bolagsverket.se). Data about these companies is an important asset for the customer relationship management market. In most business areas, users are in search for new customers. Companies, such as Lundalogik AB, provide a service, where the analysts can look for customers in an interactive environment
Examensarbetets syfte är att undersöka yrkesarbetares medvetenhetsnivå kring olyckor på arbetsplatser, personlig inställning till medvetet och omedvetet risktagande samt förebyggande av arbetsmiljöskador. Studien skall ge en indikation om vilka de bakomliggande faktorerna är till att yrkesarbetare tar risker i arbetslivet. Undersökning kommer också inrikta sig på att undersöka om det finns några tThe purpose of the master thesis is to investigate the workers level of awareness of accidents on the work place, personal attitude towards known and unknown risks and how to avoid them. The study will give an indication of the root causes of the risks the workers are taking at the construction site. The study will also research if there are any clear correlations between endangerment and age, gen
In a time where peer-to-peer networks, often with previously unconnected devices, are increasing in relevance, new storage solutions are needed. Storage can no longer rely on a single central entity but rather needs to depend on the resources of the entire network. Such a solution is the distributed hash table (DHT) which allows distributed storage of resources, ensuring redundancy and availabilit
Encapsulation systems have long been studied, and the designs have varied in both capsule material as well as the type of cargo. The intended use have ranged from nanoreactors to delivery systems. This work presents an encapsulation system consisting of protein capsule and a protein cargo. The capsule is a redesigned hepatitis B virus capsid protein, in which the luminal extension has been altered

Inversions have the capacity to maintain genetic differentiation between hybridizing populations, which makes them highly interesting targets for understanding the processes of early speciation. In-versions can generate “islands of differentiation”, genomic peaks of heightened divergence, by lower-ing recombination in heterozygotes. Two genetically similar and hybridizing subspecies of the willow
An extensive part of the road network in Sweden still consists of gravel roads, but operation and maintenance of these roads is complex due to the Swedish climate and the low traffic volume. This report further examines how operation and maintenance of gravel roads is executed and how it can be done in a cost effective way. In order to do so, the report contains both a literature study and a field
This thesis presents a finite element solution to the problem of swelling inclusions inside a host matrix. The FE simulations aim to mimic the behaviour of hydrides nucleating and growing inside a zirconium body with a heat expansion analogy, this is done with both a multi-step and single step technique carried out in the commercial FE software ABAQUS. The model mesh was generated with a Python sc
Syfte: Syftet med studien är att analysera hur ett framgångsrikt ombyggnadsprojekt för flerbostadshus från 1950-talet ser ut och om det finns generella faktorer som går att applicera på andra projekt. Vidare är det tänkt att studien ska belysa hur utvärderingen av projekt idag genomförs och om det finns andra variabler som borde utvärderas jämfört med vad som görs i nuläget. Slutligen ska studien Purpose: The purpose of this study is to analyze if there are any critical success factors in renovation projects from the 1950’s in Sweden, and if they can be applied to more general construction projects. Furthermore, the study will examine how these projects are evaluated and if a wider evaluation process is needed. Finally, the study will examine how the workplace affects the residents during
The aim is to specify a demand function that describes the demand for cannabis on county level in the states that have legalized retail sales in order to test hypotheses regarding what factors influence demand on county and potentially on individual level, as well as to gain some insight in whether legalization is a good strategy for combatting black markets of cannabis. Multiple regression analys
This study investigates the relation between preferences and cognitive effort in decision making tasks in a natural setting. Does the way a supermarket’s shelves are organized affect how easy it is to choose what items to purchase? Does it affect the quality of our choice? The eye-movements of participants were recorded during their regular shopping trips in two supermarkets with different shelf
