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.

Metoden var en systematisk litteratursökning som gjordes med 14 valda sökord i sju databaser som slutligen gav 15 artiklar för analys. I resultatet identifierades forskningsområdena djurägarskap och djurterapi.
Modellering och reglering av ureainsprutning på kraftvärmeverket FTG
The aim of this thesis is to improve the control of urea injection at the combined power and heating plant Framtidens Gärstad (FTG). Tekniska Verken i Linköping AB is the owner of the plant.The FTG plant consists of a boiler where garbage combustion is done. From the combustion nitrogen oxides are emitted. These nitrogen oxides are hazardous to the environment. To reduce the nitrogen oxides, injection of urea into the boiler is used.
Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.
The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.
Neospora caninum hos köttdjur i Sverige :
Neospora caninum is an intracellular parasite that was first recognized in dogs in
1984. The parasite is now one of the most commonly diagnosed infectious causes
of abortion in cattle word wide. N. caninum is transmitted to cattle in two ways.
They may be infected from eating food contaminated with oocysts from a
definitive host or they may be infected in utero from an infected mother. The
infection is transmitted efficiently from cow to her offspring and this can occur
for generations.
Genetiska defekter hos nötkreatur :
Genetic defects are caused by mutations in major genes where the gene?s protein product has a large impact on the physiology of the animal. The synthesis of the protein can be altered by a change in the nucleotide sequence, which can lead to malformation and in many cases death.One of the main reasons of increase in many genetic defects is the use of few bulls in breeding programmes, causing a reduction of the genetic variation. Genetic defects cause suffering for the animal and influences the production by, for example, increased costs due to misscarriages, lost milk production and expenditure for medical treatment. Bovine Leukocyte Adhesion Deficiency (BLAD) and Complex Vertebral Malformation (CVM) are two genetic defects that were widespread before the causative mutation was discovered.
Grazing behavior of Ankole and Boran cattle in an improved herding production system
To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.
Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM.

The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.
Från vilda till domesticerade djur - kan man gå ett steg längre?
Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Föräldrars upplevelser av bristande stöd, bemötande och trygghet i samband med vård under förlossningen på ett sjukhus i Västra Sverige
Introduktion: Ett av de viktigaste målen inom förlossningsvården är att kvinnor får en positiv förlossningsupplevelse. En positiv förlossningsupplevelse utvecklar en positiv inställning till moderskapet och hjälper till att underlätta övergången till att bli föräldrar. Trots att det framkommer i ett flertal studier att ett gott stöd, bemötande och trygghet främjar en positiv förlossningsupplevelse, förekommer det att avsaknad av dessa tre faktorer som orsakar negativa upplevelser för nyblivna föräldrar.Syfte: Syftet var att beskriva orsaker till att föräldrar inte är nöjda med stöd och bemötandet och/eller inte kände sig trygga i samband med vård under förlossningen, samt att beskriva vad som kan förbättras i stöd och bemötandet.Metod: En webbaserad enkät som besvarades av nyblivna föräldrar efter förlossningen under 2011 på ett sjukhus i västra Sverige. Web-enkäten innefattar föräldrarnas upplevelser under hela vårdkedjan, mödrahälsovård, förlossning samt BB. Denna magisteruppsats består av en analys baserad på tre slutna frågor samt efterföljande tre öppna frågor där en lägre grad av nöjdhet alternativt missnöjdhet (5%) gällande upplevelser av stöd, bemötande och trygghet i samband med barnafödande.
Psykologstudenters tankar om arbetsliv och arbetsmöjligheter : Ett self-efficacy- och locus of control- perspektiv
Tron på den egna förmågan (self-efficacy) och upplevelsen av kontroll (locus of control) påverkar människors agerande och bedömningar av sina möjligheter. Syftet med undersökningen var att öka förståelsen för hur studenter från psykologlinjen i Stockholms Universitet bedömde sina chanser att få ett arbete direkt efter utbildningen. Fyra studenter deltog i undersökningen och data samlades genom kvalitativa halvstrukturerade intervjuer. Resultatet visade att möjligheterna till att få arbete efter examen ansågs vara goda men att den praktiska tjänstgöringen för psykologer, PTP, sågs som en flaskhals. Erfarenhet, kontakter, ålder, kön och utbildningsinriktning ansågs kunna påverka möjligheterna till att få en PTP-tjänst och påverkade också deltagarnas bedömning av sina chanser.
Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.
Ekonomistyrning och Ägande: Förändras ekonomistyrningen vid ett byte av ägarform?
The purpose of this thesis is to examine how the Management Control System is affected by a change in the owner structure from family owned to not-family owned. The study also tries to identify explaining factors behind the possible effects to the Management Control System. The study is based on a comprehensive case study on the company Alcro-Beckers which, in year 2001, was acquired from the owner Lindéngruppen fully owned by Ulf G Lindén. The acquirer was the non-family owned company Kemira OY, a Finnish stock listed group. The empirical foundation mainly comes from interviews conducted with people who were/are directly connected to the company, either as employees or as representatives for the owner.
Välfärd hos växande nötkreatur ? finns den?
During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized.
The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.
