Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Koldioxidsutsläppsbesparing vid biogasproduktion

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

African swine fever in Uganda : attitudes and possible interventions to limit the spread of the disease

The objective of this study was to investigate the attitude towards African swine fever (ASF) primarily among smallholder pig farmers but also among other actors along the pork value chain in Gulu district, Uganda. More specifically, the study aimed to investigate the specific challenges facing both farmers and other members of the pork value chain using participatory epidemiology (PE). ASF is a feared viral disease of pigs associated with high mortality, which is endemic in many parts of Africa. The recent history of Gulu district in Northern Uganda can be described as turbulent and the human population has suffered during decades of war and civil unrest. Pig keeping is considered a potential opportunity for business as well as a way of providing more animal protein in the diet. However, this is threatened by ASF as farmers can lose entire herds due to the disease. This study can confirm some previously known factors and risk activities such as the free range system of pigs and movement of pigs and pork during ongoing outbreaks, which make disease control difficult.

FALSKA MINNEN OCH SJÄLVKÄNSLA - med utgångspunkt i DRM-proceduren

Does a person´s self esteem contribute in the process of creating false memories? Previous studies show that mood is related to false memories as well as to self esteem. This led to the focus of this study, to examine the relationship between false memory and self esteem. The question is examined by comparing the amount of false memories produced in the Deese-Roediger-McDermott (DRM) procedure with people´s scores on Rosenberg´s self-esteem scale. 59 people participated in a test with three different elements, a self esteem test and a memory test with both recollection and free recall.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Kisa Stationsamhälle : från kyrkoby till municipalsamhälle 1895-1905

The current field of research concerning the impact of railroads in Sweden beside from the State main-line network is relatively narrow. Including cultural impact to the area narrows the results even further. The purpose of this study is to open the field even more into the local societies and to what extent the impact of the introduction of railroad might have had on smaller county villages. Sweden holds a unique position concerning ?station towns? or ?railways towns? in terms of railway policy and the industrial development in towns that were affected by the railway, as the affected towns continued development were based on a hybrid between direct democracy and adaptations of city-law policies.This study takes place in Kisa, a small town in southern Östergötland that during the beginning of the 20th century turned into a municipal community due to the building of Östra centralbanan (roughly translated Eastern central-line).

Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Energieffektivitet i datahallar

The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

Produktutveckling - från idé till genomförande : skillnader i arbetsprocess mellan små och stora resebyråer

Tourism has been an expanding market since the first travel agency started in the middle of the 18?Th century, and today it is a global industry, with intensified competition and high demands from the customers. Product development is therefore one of the most important aspects for successful companies, and scientists also agree that the first stages in product development are the most critical. This essay is focusing on those stages, regarding product development on travel agencies, and the research question is as follows: How are new tourism destinations developed and what is the difference in working process between small and big travel agencies? The empirical research consists of qualitative semi-structured interviews with two big and two small travel agencies.

Självskadebeteende hos tonåringar : En studie rörande förekomsten av självskadande beteende hos ungdomar i årskurs nio, i relation till kön, självkänsla och grad av mindfulness

Syftet med denna studie var att undersöka förekomsten av självskadebeteende hos tonåringar, om detta skiljer sig åt mellan könen och om samband kan uppvisas med självkänsla och mindfulness.128 elever i årskurs nio från tre skolor besvarade frågeformulären Deliberate Self-Harm Inventory, Rosenberg Self-Esteem Scale samt Mindful Attention Awareness Scale.Resultaten visade att 65,9 procent av deltagarna skadat sig själva vid åtminstone ett tillfälle, och 41,4 procent vid flera tillfällen. Det förekommer ingen signifikant skillnad mellan könen. Hos flickorna korrelerar självskadebeteende med låg självkänsla och låg grad av mindfulness. Pojkar som skadat sig själva många gånger uppvisar lägre grad av mindfulness än övriga pojkar. Resultaten indikerar att det troligtvis finns flera olika anledningar till att ungdomar skadar sig själva..

Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Den rättvisande bilden och K2 : en studie utifrån revisorernas perspektiv angående begreppet rättvisande bild vid tillämpning av K2 och dess förenklingar

In recent years there have been major changes in the accounting field and the question of what is fair and accurate reporting is always a relevant issue. Defining the concept of true and fair view and to find an accurate synonym is difficult, still it may be considered that there is an implied meaning of the concept in the business of accounting. In 2004 BFN started the development of K2, a simplified regulatory framework for small companies. The purpose of K2 is to facilitate the accounting and reduce the administrative burden for these companies. In Sweden, 95 percent of all companies belong to the category of small companies and are allowed to use the new and simplified regulations, K2.

Dialektens retorik : En studie om dialekter som retorisk resurs

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.
