Varför är Bivarödsånsvatten så brunt?

The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

Villkorslös Solidaritet? Om intresseheterogenitet inom Europafacken

This thesis deals with the supranational organization of European trade unions. The European trade union movement is, via its umbrella organization the ETUC, an institutionalized social partner within the European Union. The ETUC is a very diverse organization with great potential of conflicting interest among its members. This thesis therefore seeks to explore the dynamics and interest heterogeneity of the ETUC. Drawing on previous research and literature it formulates a number of hypothesises to test what variables that influence the member organizations policy preferences (i.e.

Kravinsamlingsmetodik : motivering av metodvalet

Det är idag fortfarande en stor del av alla IT-projekt som misslyckas och kravhanteringen har fått en större betydelse för om ett IT-projekt ska lyckas eller inte. För att en större möjlighet till att ett IT-projekt ska lyckas används kravinsamlingsmetoder, dock är det viktigt att rätt kravinsamlingsmetod väljs till det specifika projektet. Om fel kravinsamlingsmetod väljs från början kan detta ledda till en misslyckad systemimplementation. Därför har författaren av rapporten valt följande huvudproblemfråga att undersöka i denna uppsats: Vilka råd rörande metodval kan ges till organisationer som ska implementera och välja en kravinsamlingsmetod? Med hjälp av enkäter och djupare intervjuer har författaren samlat in tillräckligt med material för att spegla de svar som framkommit i slutet av rapporten.

Stabilisering av betongstommar : Beräkning av en ekvivalent beräkningsmodul med hänsyn till samverkande kort- och långtidslast

Vid stabilisering av betongstommar är det komplicerat att välja en korrekt elasticitetsmodul. Detta då stommens laster verkar under både kort och lång tid. I detta examensarbete utförs en noggrann kryptalsberäkning för varje plans vertikala element, där hänsyn tas till den varierande byggtiden. Utifrån det analyseras kort- och långtidslaster med respektive elasticitetsmodul för att erhålla en ekvivalent elasticitetsmodul som tar hänsyn till de olika belastningstiderna. Denna elasticitetsmodul bestäms efter förhållandet mellan stommens knäcksäkerhet, snedställning och den vindlast som verkar på byggnaden.Den ekvivalenta elasticitetsmodulen ligger till grund för mer noggrann indata än tidigare vid stabilitetsberäkningar och redovisas i diagram som sedan kan användas i det praktiska ingenjörsarbetet.Där inget annat anges utförs beräkningar enligt Eurokod 2.Där inget annat anges är figurerna ritade av författarna..

CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

Actor interaction in the EIA process in Sweden : case study of Tönsen wind power park project

In the growing concern for the state of the environment more tools are being integrated in the decision-making processes. Sweden actively makes use of environmental impact assessment (EIA), which is supposed to minimise negative impacts of a project, policy or plans on the environment. The EIA process in Sweden still requires certain improvements to be more efficient. In this study actor interaction was analysed with trust being the framework for analysis. The aim is to find out whether it is possible to use trust as a framework for analysis since trust research is very discipline dependent.

Är verkligheten indelad i ämnen? - en undersökning av elevers upplevelser av ämnesövergripande arbetssätt i tematisk form

Our purpose with this essay was to explore students? experiences of interdisciplinary working method in thematic form. With a starting point from Lpf-94, the curriculum for the upper secondary school and several theories of learning, we wanted to explore if interdisciplinary working method in practice could create an environment for a meaningful learning situation. The study took place in an upper secondary school class, study preparatory, third grade, who works interdisciplinary in thematic form. Our study was qualitative and we used an open structural questionnaire where the students confidentially were able to describe the working method, explain which subjects that participate in the work, and bring forward good respectively bad factors about the method.

Doing Business in China - A Best-practice Model for Foreign Invested Small and Medium-sized Enterprises (SMEs)

Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.

Mezzanine - en efterställd fordring: En utredning av rättsliga förutsättningar vid obestånd för fordringsmezzanine

Mezzanine is a collective term for hybrid instruments on the leverage finance market, offered as an alternative to traditional debt. As a hybrid, mezzanine combines elements of debt and equity financing. Mezzanine appears, in its most common shape, as subordinated to the senior debt, but ranks higher than pure equity. Reminiscent of security interests, the main importance of subordination is upon the default of the borrower. Therefore, the aim of the thesis is partly to investigate the legal prerequisites for a solid subordination of mezzanine financing, and partly to explain the consequences of subordination in a default.

Vad det nu hette...Jämställdhet...? : Ett utredningsarbete på en klinik

The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.

Den omedvetna texten : En psykoanalytisk studie över affektens och överföringens betydelse vid tolkning och läsning av skönlitteratur

The aim of this study is to explore the fundaments of all psychoanalytic interpretative models, and especially the psychoanalytic literary criticism. Drawing from different fields as affect theory, neuropsychology and Lacan's structural psychoanalysis, strong evidence is found that language in itself contains and transmits affects.The empiric study indicates that different readers of a text, regardless of their interpretation of the text, show similar changes in mood as a function of the text. This seems to be possible as an effect of the separation of the sign between the signifier and the signification. And this supports that the signifier has some kind of direct access to the affects. This is due to the fact that the signifier belongs to the imaginary protolinguistic level while the signification belongs to the symbolic and linguistic level of a higher order.

Kommersiella Fastighetshyror och Finansiell Stabilitet

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

Towards a function for an Arabidopsis protein involved in sucrose dynamics

System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.
