Perkolationsfilter : En undersökning av reningseffekt med avseende på järn och mangan
This master thesis has been done in cooperation with Sweco Viak AB in Sundsvall. The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign and find a demouldning of the filter that gives sufficient purifying with a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done.As test filters 10 L bars were used and the experimental work was performed at thewaterworks in Hassela and Munkbysjön.In Hassela different sandfractions were tested.
An enriched arena for lamb - anticipation behaviour before entering the arena, effects of skipping the anticipation phase and effects of being denied access to the arena
This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

Performance of laying hens in a cognitive bias task : effect of time since change of environment
In the debate on laying hen welfare, and specifically housing conditions, the main focushas been on physiological and behavioural measures. What is lacking is knowledge of howthe hen experiences the situation ? her state of mind.This study is an attempt to gain insight into the private mental states of former batteryhens. It uses a cognitive bias method based on spatial judgement, i.e. judgement of aambiguous stimulus placed spatially in between a reinforced and an unreinforced stimulus.This method has previously shown differences in judgement by animals in enriched versuspoor housing.
Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)
Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to
impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in
deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate
deciduous forest.
Patienters upplevelser av ventilatorvård på IVA : en litteraturbaserad studie
Patienter som vårdas på en intensivvårdsavdelning (IVA) är allvarligt sjuka och behöver specialiserad vård. En del av den vården är ofta ventilatorbehandlingen som kan uppfattas som en mycket mentalt påfrestande upplevelse. Syftet med denna litteraturbaserade studie var att beskriva patienters upplevelser av att vårdas i ventilator på en intensivvårdsavdelning. Datamaterialet har utgjorts av kvalitativa studier med ett patientperspektiv, vilka har analyserats kvalitativt. I resultatet framkom två huvudteman; Verkliga upplevelser och Overkliga upplevelser.
Den sista utvägen... : ? En kvalitativ studie om psykiatripersonal och brukares inställning till elektrokonvulsiv behandling (ECT).
ABSTRACT Nature of essay: C-level, 15 pointsPage count: 47Title: The last way out?-A qualitative study of psychiatric staff and service users attitude to electroconvulsive therapy (ECT).Author: Hanna Nilsson Purpose: The purpose of this study is to investigate attitudes to electroconvulsive therapy (ECT) of professionals and service users within a user organization ? Riksförbundet för social och mental hälsa. (RSMH)Questions: Does the psychiatric staff believe that there are preconceptions about electroconvulsive therapy? What motivates service user?s choice of electroconvulsive therapy? Do the psychiatric staff and the service users think that the positive effects of ECT can outweigh the possible negative side effects?Method: Qualitative study. The study is based on interviews with psychiatric staffthat works with electroconvulsive therapy (ECT), and with services users who have received electroconvulsive therapy (ECT).Results: The result showed that the psychiatric staff feels that preconceived ideas occur about the treatment of ECT, and that it is affecting their approach to work.Service users motivate their choice by how bad they felt under the depression, and that ECT was their only choice left, that´s why psychiatric staff suggested the treatment.The positive effects of ECT outweighed the possible negative side effects because life is something you value higher than any memory loss and when there is currently no treatment having a similar efficiency.Keywords: Electroconvulsive therapy, Attitudes, Side effects, Experience, Patients, Professionals.
De första på plats: En fallstudie av entreprenörers resonerande vid etablering på en ung marknad
One of the areas in which current theory on entrepreneurship is ambiguous is in the explanation of how entrepreneurs act when entering a new market. One author that has attempted to contribute in this area is Saras D. Sarasvathy who has tried to explain the entrepreneurs reasoning through the theory of causation and effectuation. The former refers to a reasoning that takes the effect of an entrepreneurial action as given, while the latter looks upon the effects as uncertain, while only the means are given. With a foundation in this theory, Sarasvathy claims that when entrepreneurs enters a new market the level of environmental uncertainty is so high that reasoning based on causal relationships is rendered useless.
The effect of training on spontaneous blink rate in dogs
The spontaneous blink rate is found to be a non-invasive but functional, reliable and useful way to monitor central dopaminergic activity. Dopamine is associated with a range of functions such as reward, motivation and learning. It plays an important role in goal-directed behavior and in maintaining a behavior once a task is learned. As far as the author knows, there are today no publications that discuss the topic regarding the possible link between training and spontaneous blink rate in dogs. Therefore, eight privately owned dogs were included in this study to determine if there was a significant difference in the spontaneous blink rate before and after the process of learning a task.

Kontrollerande aktieägare och företagsvärde : En empirisk studie av hur den kontrollerande aktieägarens kapitalandel respektive röstandel påverkar ett företags värde
Via semantisk analys har förekomst och variation av KRAFTmetaforer i två olika typer av texter jämförts. Hypotesen är att kognitiva neurala nätverk som ansvarar för den abstrakta tanken är tätt sammanbundna med kognitiva neurala nätverk som representerar känsloerfarenhet baserat på sensoriska upplevelser. Analysen utfördes på två olika typer av texter. Resultatet visar på signifikant skillnad i förekomsten av antalet metaforer i de olika texterna. Ett antagande för undersökningen var att självbiografiska texter är mer förankrade i känsloerfarenhet baserat på sensoriska upplevelser än vad argumenterande texter är.
Matematiksvårigheter : En studie om fyra pedagogers erfarenheter kring matematiksvårigheter med exempel på pedagogiskt arbetssätt
For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

Hur bemöts Kina i Afrika? : En mångdimensionell idealtypsanalys av Sydafrikas, Zambias och Zimbabwes bemötande av Kinas ökande ekonomiska intresse
The outset of this study is to contribute to the literature concerning China?s increasing economic interest to engage in the African context, its economies and resource abundandce. The overarching research problem is that the approaches held by the respective African state entities may facilitate increasing development gains for the recipient state of this economic interest in principle. To adress this research problem the study is undertaken by conducting a comparative case study where three cases/states, with presumably diverging economic and political status, are likely to effect their overall state approaches differently.Research questions, which are addressed by the creation of an idealtype analytic matrix, concern whether the states of South Africa, Zambia and Zimbabwe take on a more ?permissive? or ?restrictive? approach towards China?s economic interst and whether the approaches can be looked upon on both aggratege and case/area-specific levels.The main findings are that a clear tendency of the ?permissive approach? may be noted on a aggregate level for all cases.
