Avdelningen för strömningslära vid Luleå Tekniska Universitet har en vindtunnel som främst används till utbildning i aerodynamik för studenter. I skrivandets stund finns bara en vinge (osvept) som tillåter att 3? dimensionella effekter kan studeras och jämföras med en vinge som har 2? dimensionell strömning av samma sorts vingprofil. Resterande vingar har bara 2?dimensionella egenskaper eftersom deras spann sträcker sig från vägg till vägg i vindtunnelns testsektion.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

It was the purpose of the present study to explore thoughts and lines of reasonings concerning body perspectives in school. Based on students at a secondary school and on analyses of the curricula of the school, I reason about how we see the human being and the importance of it in school. In the introduction I start out from observations and highlight the body as a communicative channel leading up to the issue of students? basic view of man as integrated or devided in body and soul. A study of twelve interviews of students shows that thoughts about the two perspectives had not been identified until now but that a great deal of interest existed for discussion on this subject.

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

When professionals meet people from other cultures, there are some problematic issues that may appear, especially when considering human rights. Every individual has the right to live as they choose, and have the right to their own culture and traditions even if they have immigrated to another country. Female genital mutilation is a tradition that violates human rights. In this study we will look at what conflicts of values that professionals can have while meeting clients who have been mutilated. We have made qualitative interviews with four professionals working in a small town in Sweden in an area where many immigrants live.

This thesis examines interfaith work from a general perspective and through the Swedish interfaith project ?Tillsammans för Sverige?. They are based in a famous youth center in Stockholm. The examination has two aims. The first is to identify the main characteristics of interfaith work and how they correspond with daily practice.

Since the 1990s, when the number of transnational companies increased, it has created challenges regarding the responsibility of human rights. As a response to these challenges the United Nations Human Rights Council (UNHRC) unanimously endorsed the new policy UN Guiding Principles on Business and Human Rights (UNGP) in 2011. UNGP does not have the status av international law, yet simply as guidelines and its implementation is based on good will and voluntary efforts. Now, 10 years later, this study aims to get understanding regarding if UNGP is considered as norm by the Swedish Government, Volvo and Gothenburg Municipality. The material of the study consists of sustainability reports, annual reports and governmental documents with focus on human rights in relation to business published between the year of 2011, when UNGP was endorsed, until 2020.

Studiens syfte var att undersöka och sätta ord på medarbetarnas upplevelse och uppfattning av delat ledarskap utifrån två teman: verksamhetsaspekter och personalaspekter. De teorier som det relateras till i uppsatsen är Döös med fleras teori om delat ledarskap, Engquists kommunikationsteori, Hällstens & Tengblads medarbetarskapsteorier samt Thylefors ledarskapsteorier inom Human service organisationer. För att genomföra undersökningen användes en abduktiv, kvalitativ metod med tre strukturerade fokusgruppsintervjuer med medarbetarna samt två individuella intervjuer med två delande chefer på tre verksamheter inom Human service organisationer, där konceptet med delat ledarskap tillämpas eller har tillämpats.Medarbetarnas upplevelser av delat ledarskap har skiftat från nöjd till missnöjd. Resultatet visar att delat ledarskap ger flera fördelar och få nackdelar om rätt förutsättningar finns. Slutsatsen är att delat ledarskap är något alla tjänar på ?om uppdelningen av det delade ledarskapet är väl genomtäkt och personerna som delar ledarskapet passar in i rollerna?.

Arbetet har utförts på Saab Bofors Dynamics i Karlskoga och dess syfte var att undersöka om det är möjligt att använda modellbaserad prediktionsreglering, MPC, vid slutfasstyrning av en viss typ av robot. Som referensram används linjärkvadratisk reglering, LQ, eftersom denna reglermetod har undersökts tidigare och visat sig fungera bra vid slutfasstyrning, dock för en annan typ av robot. Anledningen till att man vill undersöka om det är möjligt att använda MPC är att styrlagen enkelt tar hand om begränsningar på systemet på ett direkt och intuitivt sätt.Styrlagarnas uppgift är att styra en robot i dess slutfas då det finns krav och önskemål på roboten som bör vara uppfyllda. Till exempel finns det begränsningar på styrsignalen samt önskemål om att träff ska ske i en viss träffpunkt och även med en viss träffvinkel. För att utvärdera resultaten undersöks och jämförs de två styrlagarnas prestanda och robusthet.För att kunna utvärdera styrlagarnas egenskaper och jämföra dem implementeras de båda i en befintlig detaljerad simuleringsmiljö, som har utvecklats på Saab Bofors Dynamics i Karlskoga.De prestanda och robusthetstester som har utförts uppvisar små skillnader på de två styrlagarna och slutsatsen blir därmed att det är möjligt att använda modellbaserad prediktionsreglering vid slutfasstyrning av en viss typ av robot eftersom det sedan tidigare är känt att linjärkvadratisk reglering är en bra styrlag att använda.

Title: The dynamics of the Audit expectation gapIntroduction: The audit expectations gap is the difference that exists between what auditors and users of accounting information expects an independent auditor to do. Since the definition arose in 1974, much research has been done about the gap. What is relatively unexplored is how the gap changes over time within a country, and how it is affected by external events. This lack of knowledge has motivated this study.Problem: How has the audit expectation gap changed in Sweden, from the emergence of the definition until today? In which way have corporate scandals and legislative changes affected the gap?Purpose: The aim is to identify and create an understanding of how the audit expectation gap has changed in Sweden.
