Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.

In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Studien genomfördes i syfte att undersöka vad som driver en människa att arbeta mot en låg eller ingen monetär belöning. Det teoretiska ramverket Self- Determination Theory möjliggör kategorisering av en individs motivation i såväl inre som yttre motivation och även att mäta graden av motivation. Tidigare studier på området har indikerat att individer kan välja yrken med låg lön tack vare inre motivationsfaktorer. Denna studie ämnar fylla ett forskningsgap i redogörelsen för huruvida yttre motivationsfaktorer som social bekräftelse och kändisskap kan driva personer till att arbeta mot en låg monetär ersättning. Datainsamlingen skedde genom besöksintervjuer med människor som arbetar som fotomodell.

I hälsoprofessionen är beteendeförändringar gällande fysisk aktivitet och kost centralt. Self-Determination Theory är en motivationsteori som i forskning använts för att undersöka motivation till fysisk aktivitet. Det finns däremot mindre litteratur som kopplar teorin till hälsosamma kostvanor. Studiens syfte är att kartlägga och jämföra motivation och målsättning till hälsosamma kostvanor hos en grupp studenter. Studien avser kartlägga samband mellan fysisk aktivitetsnivå, motivation och målsättning samt jämföra könsskillnader.

Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Trots att organisationer satsar alltmer på utbildningsinsatser, står det inom forskningen fortfarande oklart vad som leder till faktisk förändring i det fortsatta arbetet. I denna studie undersökte vi utifrån Baldwin och Fords transfermodell vilka individ-, design- och miljöfaktorer som förklarade en grupp  Försvarsmaktsanställdas upplevda kunskapsinhämtning och transfer efter genomförd utbildningsinsats. Detta skedde med Self-Determination Theory (SDT) som teoretiskt ramverk genom en enkätundersökning. För kunskap var autonom motivation (AM), kontrollerad motivation (KM), upplevelse av autonomifrämjande implementering samt behovsstöd från chef förklarande faktorer. För transfer var autonom motivation, upplevelse av autonomifrämjande implementering samt kunskap förklarande faktorer.

Syftet med studien är att undersöka huruvida det är mer eller mindre motiverande för anställda inom mjukvaruindustrin att jobba enligt agila utvecklingsmetoder än enligt traditionella utvecklingsmetoder.Undersökningen har gjorts med teoretisk utgångspunkt från motivationsskapande variabler ur de kontemporära motivationsteorierna Self Determination Theory samt Job Characteristic model.Som en ansats till att besvara frågeställningen har en kvalitativ fallstudie genomförts på företaget Kambi Sport Solutions AB. Kambi Sport Solutions AB har under de senaste åren genomfört en organisationsförändring där traditionella projektledningsmetoder ersatts av agila projektledningsmetoder.Studiens empiri visar med stöd ur motivationsteori att övergången till agila metoder signifikant påverkat individens motivation positivt. Framförallt som en följd av en högre grad av självbestämmande, kunskapsvariation, identitet i och betydelse av arbetsuppgiften, autonomi samt feedback.  .

Rotavirus and coronavirus are the two most common viral causes of neonatal calf diarrhea and their presence causes a lot of economic damage to the farmers as well as suffering to the animal. By getting better knowledge about the viruses we may help in tracing transmission and in producing new vaccines. This paper served to study the molecular epidemiology of rotavirus and coronavirus in fecal samples collected from two different farms in the state of São Paulo, Brazil. These samples have been studied with focus on the gene VP4, VP7, NSP4 in rotavirus and the gene S1 in coronavirus. From the first farm the screening PCR showed that 12/48 samples were positive for rotavirus and 4/48 positive for coronavirus.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Motivation inom skolan är avgörande för elevers lärande. I self- determination theory (SDT) betonas vikten av inre motivation genom autonomi, kompetens och samhörighet. Stöd, höga förväntningar och målsättningar har visats sig ha positiv inverkan på motivation. Syftet med denna undersökning var att studera vad som främjar ungdomars motivation, med utgångspunkt i SDT samt ungdomars och vuxnas perspektiv, utifrån skilda tillvägagångssätt i motivationsarbete. Intervjuer genomfördes med 8 deltagare från en friskola och 8 från en ungdomsverksamhet.

The test battery ?fysprofilen? was performed at three test occasions, October 2011, May 2012 and October 2012. Muscle strength was evaluated with squats, bench press and grip strength; power was evaluated with power clean, squat jump, countermovement jump with and without arm swing, Harre´s test and the 30 meters sprint.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.
