Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie
Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

"Hur dricker du?" : En studie av kommunikationsstrategiers utfall hos målgruppen med avseende på olika konsumtionsbakgrund
In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.
Spännkraft på bandavskrapare : Utredning och konstruktion
This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

Temperature monitoring during transport of test samples
Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.
Svensk delnormering av Lundamaterialet för åldrarna 3:0?5:11 år och undersökning av materialets effektivitet
The purpose of this study was to collect Swedish normative datafor Lundamaterialet for children aged 3:0-4:5 years. Another aim was toexamine the effectiveness of the test; if it elicits adequate responses fordeciding if a child has acquired a specific language structure or not.Normative data was collected for 195 children with typical languagedevelopment. Participants were recruited from pre-schools in themunicipalities of Göteborg, Mölndal, Härryda and Skövde. This studypresents normative data for 79 children constituting the three youngest halfyeargroups. Results show that the children had acquired more than half ofthe investigated phonological and grammatical structures and that the olderchildren had acquired more structures than the younger ones.
Får elever bättre uppmärksamhetsförmåga efter fysisk aktivitet? : En experimentell studie om fysisk aktivitets påverkan på uppmärksamhet
The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.
Jaktprov hos brittiska stående fågelhundar
In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures.
Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

Test av spädbarns nyhetspreferens med ögonrörelsemätare
Fagan Test of Infant Intelligence (Ftii) är ett parjämförelsetest som mäter spädbarns intresse för ett nytt visuellt stimuli när detta presenteras tillsammans med ett stimuli redan känt för spädbarnet, kallat nyhetspreferens. Även om Ftii har visat sig fungera väl vid bedömning av spädbarns kognitiva nivå kan testet förbättras på ett antal punkter. För att uppnå reliabla resultat har försökspersonerna ofta testats vid ett flertal tillfällen. För att undersöka möjligheterna att ytterligare validera erhållna resultat från Ftii har en version av Ftii skapats för att utföras med en ögonrörelsemätare. Denna version, kallad Ftii-Ö, har testats med hjälp av en spädbarnsgrupp och en vuxengrupp för att på så sätt utvärdera för och nackdelar med ett test utfört på ögonrörelsemätare.
