Variation in protein precipitation and phenolic content within and among species across an elevational gradient in subarctic Sweden
This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.
Gymnasieelever och fostran av demokratiska medborgare : En enkätstudie av elevgruppers nivåer av moraliska och kognitiva utveckling.
This study is grounded in an interest in the Swedish Upper Secondary Schools? role as an educator of democratic citizens, with a specific interest in the moral and cognitive development of Upper Secondary School students. Development in these two areas is treated as results of citizenship education.The purpose of the study is to examine moral and cognitive development of students in Upper Secondary School to see if there are any structural differences to be found between the Upper Secondary School programs that are vocationally oriented and the programs that are preparing for further studies on higher levels ? since these differences have been both theoretically and empirically implied. The study is based on an enhanced version of Lawrence Kohlberg?s stages of moral development (with teachers? evaluations of students? capacity as a reference point of the students? actual level of moral development) as well as on Kieran Egan?s theory of development through the use of cognitive tools (as seen in five different ?shapes of understanding?).
Increased growth in Norway spruce (Picea abies (L.) Karst.) through small annual additions of nitrogen (N) fertilizer

We were also interested in finding out what they think is the joy and amusement in the leadership and how they consider responsibility and authority. We used a qualitative method interviewing female leaders at their work. In our analysis of the data we have looked for pattern and key words in a qualitative way.
Utvärdering av den bärande tegel- och betongstommen i en byggnad från år 1916
This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
Utveckling av handhållen pump för reumatiker
Denna rapport är resultatet av ett examensarbete motsvarande 30 högskolepoäng på Civilingenjörsprogrammet Teknisk Design, inriktning produktutveckling, vid Luleå Tekniska Universitet (LTU). Arbetet är utfört under vårterminen 2012 och går ut på att utveckla en ny typ av handhållen pump för personer med reumatism. Uppdragsgivaren och projektägaren är Fredrik Martinsson på Bumblebee Solutions i Mölndal, men arbetet har utförts på egen hand vid LTU. Syftet är att utveckla en ny produkt som underlättar för personer med reumatism och nedsatt rörlighet i händerna att pumpa bil- och cykeldäck. Dagens pumpar bygger på relativt föråldrade konstruktionsmetoder som innehåller många besvärliga moment.
Energieffektivisering av skolbyggnad från 60-talet : Studie av Hållsta skola i Eskilstuna
In June 2006 the Swedish government decided that the use of energy in buildings should be reduced by 20 percent until 2020, compared to the level of energy used in 1995. To contribute to this goal, the real estate company ?Eskilstuna Kommunfastigheter AB?, set up own goals for their buildings. In 2009, the goal for schools was to have a maximum energy use of 118 kWh/m2year for heating and hot water.The school ?Hållsta skola?, just south of Eskilstuna, exceeds the limit since it used 270 kWh in 2008.
Solavskärmning med solceller och dess inverkan på energianvändning och inneklimat
In this thesis an explorative study was undertaken with the aim to study how a number of private care providers, as well as politicians and officials from councils in and around the Stockholm and Uppsala counties, think about the future of the Swedish elderly care from a property perspective, i.e. homes for the elderly. The analysis shows that there is a demand for capacity in 6 out of 16 municipalities, and that the property is an important part of this capacity, and the fulfillment of it. This was mainly due to the cost of capital, but also because of several other factors such as lack of land, a wish to guide the design, ideology, and in many cases a wish to use the property as an instrument of domination to control private health care providers.Also, the property was show to be connected to economic competition, to freedom of choice, and to quality. The problems related to the property in the market for elderly care still remains to be solved.
Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank
The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.
New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production
The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.
Inverkan av försvagningar på bärförmåga för stålbalkar med långa spännvidder : En jämförelse mellan Eurokod och BKR
The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.
Översyn av uppvärmning
The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.
Varierande Vägar till Frihet - Hur staten och civilsamhället interagerar för demokrati i Vitryssland, Moldavien och Ukraina
The three post-communist states - Belarus, Moldova, and Ukraine ? have gone different ways in terms of freedom and democracy since the breakdown of the Soviet Union 1991. During these years, the state and the civil society have been fundamental actors in the struggle against, and even for, authoritarianism.A strong state with great capacity in Belarus has undermined the chances for the civil society to fulfil its task as a watchdog of the state and link between the citizens and the government.Failed authoritarianism in Moldova has led to a situation where both the state and the civil society are weak. The major problem is lack of organization and cohesion; both the state and the civil society have often been divided by ethnical differences and are therefore not strong enough to promote democracy.In Ukraine, the dominance of a strong state ended in 2004 when the Orange Revolution took place, sometimes called a ?peak of democracy? where popular mobilization and protests succeeded in it's opposition against the state.
