Studie och riskanalys av sulfidleror i Uppsala stad

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

Price transmission dynamics of Chinese ADRs listed on the NYSE

Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.

Revisionsutskott i svenska aktiebolag: En statistisk analys

The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.

"Idrott för alla" : En studie om elever utanför föreningsidrotten och hur de upplever ämnet idrott & hälsa

I denna studie undersöks orsaker till att vissa elever inte är aktiva i någon föreningsidrott samt hur idrott och hälsa kan få fler elever intresserade och engagerade i föreningsidrotten. Fokus har varit att undersöka de föreningsinaktiva elevernas perspektiv och hur deras motivation i ämnet idrott och hälsa ser ut.Studien utgår från strukturerade intervjuer med tio elever samt en svensk version avSport motivation scale och Academic motivation scale för att tydliggöra elevernas motivation. Resultatet visar att de elever som inte är aktiva i en idrottsförening har låg motivation till idrott och hälsa. De anledningar som framkommer till att eleverna inte är delaktiga i någon idrottsförening är främst att de inte har något intresse eller har andra intressen. Även tidsbrist och för seriös satsning inom idrottsföreningarna uppges som orsak till att inte delta i en idrottsförening.

The effect of additional nitrate and sulfur in the diet on the methane production in cattle

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

Produktutveckling av gurka :

Abstract Cucumber is the second most frequently consumed vegetable after tomatoes, 33 % are eating cucumber every day. The purpose of this work is to examine if there is any product development of cucumber in Sweden, and if so in what way. A questionnaire was used with a number of questions regarding quality, origin, supply and the way cucumbers were used, and the person was also asked to choose between the normal large cucumber and the minicucumbers. This was answered by totally 100 persons in two different stores, ICA Maxi in Löddeköpinge and a discount store with a large supply of fruit and vegetables and where a large share of customers are immigrants, Özen All Frukt in Malmö. The results from questionnaire show that in some of the issues the results vary a lot between the two stores.

Effekt av olika stretchmetoder på agility och rörlighet hos elitinnebandyspelare

Bakgrund: I många idrotter såsom innebandy används vanligen statisk stretching (SS) som en del av uppvärmningen i tron om att öka prestation trots att statisk stretching har visat sig ha negativ inverkan på aktiviteter som involverar styrka, power, sprint och agility.Syfte: Syftet med föreliggande studie var att undersöka om olika stretchmetoder SS, dynamisk stretching (DS) och ingen stretching (IS) som en del av uppvärmningen påverkade agility och/eller rörelseomfång (ROM) i hamstring hos manliga innebandyspelare i superelitligan och om en eventuell effekt varade upp till 10 min in i testtillfället.Metod: Vid tre testtillfällen testades de olika stretchmetoderna (SS, DS och IS) efter avslutad uppvärmning. Alla tre stretchmetoderna utfördes vid varje testtillfälle efter randomiserad ordning på tre olika grupper. Agility och rörlighet testades med T-test (s) och passive straight leg raise test (o) vid 0 min, 5 min och 10 min efter avslutad stretching. Totalt 9 testpersoner slutförde studien.Resultat: Vid både 0 min och 5 min efter avslutad stretching noterades bäst tid på T-test (s) efter DS (10,20 ± 0,98 samt 9,92 ± 0,49). Vid 10 min noterades bäst tid efter IS (9,68 ± 0,16).

Skärvor i både vått och torrt : En detaljundersökning av ett provschakts keramik vid Ajvidelokalens västra strand

This thesis has had its focus on ceramic shards found in a trench by the late neolithic western shore of the Ajvide site. The purpose of the thesis is to investigate if there are changes in the pottery between the test trench and the ceramics found by the graves, known as the main site. The author has compared the ornaments from the test trench with an ornament schedule made from over 50 000 shards from the assumed main site. Not only changes regarding ornaments has been noticed but also new techniques and raw material. The author has also implemented two 14C datings which backs his hypothesis that the shards from the test trench are younger than the shards that made the earlier ornament schedule.

Att ta barnen på allvar : Socialsekreterares uppfattning om barnperspektivets tillämpning i barnavårdsutredningar

I syfte att undersöka psykometriska egenskaper hos Affektiv självskattningsskala (AS-18) fyllde 88 patienter med diagnos bipolär typ I (N=46) eller typ II (N=42) i självskattningsskalorna AS-18 och MADRS-S vid två tillfällen med en dags mellanrum. Principalkomponentsanalys för AS-18 genomfördes med extrahering av två komponenter. Items laddade i de delskalor de tillhörde. Intern konsistens mättes med Cronbachs alfa och överensstämmelse med Cohens kappa. Test-retest-reliabiliteten beräknades.

Språktest för medborgarskap? En postkolonial läsning av debatten kring språktest.

On the third of August 2002, in the middle of the ongoing Swedish election campaign, Lars Leijonborg beeing the leader of Folkpartiet (the Peoples Party) presented the partys new intergration programme for foreign nationals. One of the proposals was to instigate a language test for all immigrants seeking to obtain Swedish citizenship. This thesis addresses the medial debate that followed the proposal in the daily press. Using discourse analysis and postcolonial theory this thesis looks into the fact that there were not unity in the wake that followed the language test proposal resulting in one medial and one popular discourse. The newspapers investigated were largely negative in their tone, whereas on the opinion pages, the view of the people seemed much more positively inclined.

Reklamprat: effekter på upplevt reklamvärde och köpintention

This thesis provides the first test of the effects of ?advertising talk?, i.e. comments, discussions and opinions about advertising. Despite its prevalence quantitative research on advertising talk has been scarce and this study is thus an attempt to fill in some blanks. Hypothesizing that advertising talk will enhance consumer-perceived advertising value as well as purchase intentions and that the effects are more pronounced for talk generated by consumers as compared to marketers, I use a fictional campaign to measure responses in an experimental study.

The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

Ambulanssjuksköterskan och höftfrakturpatienten : smärtlindring och trycksårsprevention : en forskningsöversikt

Introduction: Anxiety and depression are common among patients enrolled in psychiatric outpatient care. Ear Acupuncture is an alternative form of treatment that has been shown to relieve anxiety and depression in previous studies.Aim: To evaluate ear acupuncture as a group treatment for depression and anxietyMethod: A psychiatric outpatient clinic has been offering group treatments with ear acupuncture for anxiety and depression for 5 weeks. Participants of the study have answered self-rating scales Montgomery Åsberg Depression Rating Scale, Beck Anxiety Inventory and Sheehan Disability scale before and after the treatment period. Material was collected in the period 2008-2012 and has been analyzed in SPSS.Results: Data from 31 patients were included in the study. The results from the study showed a significant difference, between the measurements before and after treatment, with a reduction of the average values in the three different scales.Summary: From this study, it is difficult to draw any conclusions about the effect of ear acupuncture.

Torkat bioavfall som jordförbättringsmedel

The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

Verbbenämning hos vuxna med afasi : Bedömt med Action Naming Test

Förmågan att benämna verb och substantiv kan skilja sig åt hos såväl friska vuxna (Strauss Hough, 2007) som personer med afasi (Mätzig, Druks, Masterson & Vigliocco, 2009). Hos personer med afasi har skillnader mellan förmågan att benämna substantiv och verb relaterats till skadelokalisation (Damasio & Tranel, 1993). Vid afasiutredningar används ofta benämningstest för att bedöma framplockningen av ord (Herbert, Hickin, Howard, Osborne & Best, 2008).Action Naming Test (ANT) är ett verbbenämningstest som normerats på svenska (Lindahl & Oskarsson, 2011; Stenberg & Wik, 2013), men inte studerats hos personer med afasi. Syftet med föreliggande studie är att undersöka hur verbbenämningsförmågan ser ut hos personer med afasi och expressiva svårigheter, i relation till den svenska normeringen för ANT. Några av orden i normeringen var problematiska, varför en reanalys av data genomfördes av Stenberg och Wik (2013).
