Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species
The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using
patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time
and change in patch use.
Ekonomistyrning i den svenska sjukvården: En utvärdering av KPP-systemet
This thesis analyses the cost accounting system KPP and its use within the Swedish health care. KPP is designed to calculate and assign health care costs to individual patients. This would facilitate evaluations and comparisons of the costs for certain diagnosis, patient groups or clinics with a different mix of diagnosis. The study investigates the following questions: 1. Does the KPP-model theoretically work as a cost accounting tool for health care purposes? 2.
I domstolens fälla? Den Liberala Intergovernmentalismen från Utstationeringsdirektivet till Lavaldomen
This thesis aim to advance the Liberal Integrovernmentalism (LIG) developed byAndrew Moravcsik in order to order to explain how the European Court of Justice (ECJ) can make de facto EU policies diverge from what was originally intended by the Member States. More specifically it describes how the Posting of Workers Directive, Directive 96/71/EC, originally was created to shield certain Member States and their respective systems of regulating the labour market from pressure arising from the posting of workers form low-wage countries inside the EU. However, through a series of cases in the ECJ the de facto policy of the directive has changed and it is now in itself a potential threat against these systems. The Member States now find themselves caught in a ?Joint-Decision Trap?, unable to rectify the situation even though their original agreement has been turned on its head.
Bacterial contamination of eggshells in deep litter floor systemsand conventional cages in Jordan
This study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.

This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.
Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm
The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Hur styrning utan budget sker i praktiken : - En fallstudie på Ahlsell AB
På senare tid har en kritisk diskussion växt fram kring användandet av budget som styrmedel. Budgeten anses vara tidskonsumerande, resurskrävande och den anses även inte tillhandahålla relevant information, vilket har medfört att det finns företag som avskaffat budgeten som styrmedel. Men hur styrs företag utan budget och är det möjligt att styra ett företag utan budget? Det finns forskare som anser att företag som styrs utan budget får problem med planering, samordning samt styrning av aktiviteter då de saknar ett ramverk. Ahlsell AB är företag som har styrt sin verksamhet utan budget i 17 år.
Dolt i det öppna
Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.
Normalitet och styrning i en förskola för alla (Normalization and governing in a pre-school for all)
The purpose of this study is to analyze how special education is done in relation to what is considered "normal". The aim is to discuss how the normalization discourse appears in a pre-school for all and, by extension, how the need of special education is articulated in relation to the normalization discourse. This study also intends to discuss how the perception of what is normal affects special education in pre-schools. The study draws upon previous research within the special education area through which we make our position. Since there is only a few studies in this chosen field which are based on empirical data, our study indicates the importance of more research in this field.
