Historisk markanvändning på Färsna gårds inägor och utmarker
Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.
Skogen - vårt biologiska kulturarv
This article deals with the woodlands as a biological cultural heritage and how it is taken care of in the protected woodlands in Skåne, in the south of Sweden, especially the deciduous trees which is dominated by beech. High biological values have emerged as a result of grazing and different kinds of forestry. The protected woodlands have been ripped of its cultural influences which changes the biological values on which the original reasons for protection was founded..
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.
Marknadens implicita värde på det permanenta mätfelet på Stockholmsbörsen
This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.
BTJ övertygar: En retorisk analys av lektörsomdömen om barnlitteratur
The aim of this Master?s thesis is to examine how opinions and values are expressed in BTJ?s reviews of children?s literature. According to debates reviewed and interviewed librarians, many consider BTJ to be too directing when it comes to the libraries? purchases of books. Therefore I find it important to study how the reviews are written.
Tradition, Vetenskap och Upplevelse En Analys av Mindfulness och New Age i det Moderna Västerländska Samhället
The purpose of the present study is to investigate mindfulness as a New Age phenomenon in the modern western society. Since a religious phenomenon does not exist in a vacuum, but is dependent on its historical and cultural context, my aim is to give a broad depiction of mindfulness and New Age in its wider context, the historical background and the societal implications of common values, themes and concepts that are frequent in the literature, how mindfulness is presented by the authors of popular literature and also how it is presented in science. In order to bring forward a deeper understanding of New Age and mindfulness? role in the modern western society, my intention is to see how the authors of mindfulness claim validity of their doctrines in the discourse. Mindfulness attracts a wide range of perpetrators and is used in many areas in the society today.
En kostnadsanalys av energieffektiva flerbostadshus
In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.
Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor
During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.
Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
Kritik av humanismen som grund till värden i svensk skola med perspektiv från Nietzsche & Kant : En narrativ ideologianalys av läroplanens värdegrund och de oförytterliga värdenas genealogi
This thesis in Educational Sciences consists of a narrative ideology-analysis of the Swedish school's fundamental values with perspectives from the philosophy of Nietzsche and Kant, which also analyzed the same way, with the aim to trace and problematize the ideological foundations of "our society's shared values" that teachers should convey to the students. Based on a theory that a humanism crisis occurs when important values are perceived as threatened, does the introduction of the basic values of the curriculum appear as a response tosocietal changes. Nietzsche and Kant represent completely different idea currents that both have been reflected in the curriculum in which basic values have different meanings. Nietzsche has inspired social criticism, postcolonial and postmodern thinkers to a critical constructivist approach that is an asset in the multicultural classroom to deconstruct stereotypes and prejudices. That culture, ethnicity, morality and religion do not have an objective essence, but seen as social constructions, using a critical approach is a way of thinking which was developed with inspiration from Nietzsche.
Teen dating violence : Samverkar våld i relationen depressiva symptom hos ungdomar?
This paper examines dialect as a rhetorical means of persuasion. A survey containing inquires about four different Swedish dialects have been handed out mainly in Södertörn University and Stockholm University, in order to research the values and connotations of theese dialects. The four chosen dialects are as following: Göteborgska, Stockholmska, Norrländska and Skånska. The results of the survey are processed and compiled to see which attitudes these values and connotations may indicate to each dialect. These attitudes and values are then discussed in correlation with five rhetorical theories: Attitude as a means of persuation, Ethos, Persona, Rhetorical Agency and Pierre Bourdieu?s theory of Field and Habitus.
Gräsmattans "vara eller icke vara" : En undersökning av den traditionella gräsmattans moderna dilemma
The traditional lawn is believed to be facing a dilemma. On one hand, it is valuable for people because of its esthetical and functional values. On the other hand, the lawn is perceived as a monoculture without biological diversity that hinders the domestic landscape?s flora and fauna. In this graduation-thesis, the private and public lawn?s dilemma of ?to be or not to be?, is examined from these two different perspectives.
Att skapa fria, demokratiska och solidariska medborgare : En essä om att granska våra normer
This essay is about power, democracy, solidarity and equality in preschool. I examine three different situations to determine if I could have acted more sensibly in my interactions with the children. I portray: a ?children?s choice meeting? where children select an activity, a so-called emotional gathering and a dialogue at the lunch table about a popular movie that we plan to watch together afterwards. The purpose of this essay is to examine which norms and values form the basis of my actions, and if so, how these lead me to use my power to shape the children.I have chosen to use hermeneutic and norm-critical perspectives where I investigate and examine my norms and values and how I react and act, both consciously and unconsciously.
Organizational Identity Construction - A qualitative study made in three different contextual settings
Our findings show that depending on the contextual setting and what sort of merger an organization goes through, the identity strategies will differ. We see that symbols and values are two objects of relevance in our case companies? identity strategies, but that there are differences in how they are being used. There is consensus around the fact that values are important to have, however their meaning to each organization differs and it has also proven to be dependent on what position you possess in the company. We have developed a four-fielder in order to further illustrate our findings.
Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle
The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable.
The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.
