On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Studenter med ett icke-tonspråk som modersmål brukar ha svårigheter att lära sig de kinesiskatonerna när de börjar sina studier. Å ena sidan brukar kursböckerna på denna nivån användabara enstaviga ord och det har ansetts vara god pedagogik att läraren visar tonkonturerna medsina händer. Å andra sidan har forskningen om kinesiska länge varit koncentrerad på vilkavärden som grundtonen (F0) uppvisar i enstaviga ord. Det är många faktorer som tvärspråksforskningeninte har uppmärksammat, bl.a. det inflytande som konsonanterna har på F0 (vilketinfödda talare inte alltid är medvetna om).Det finns ingen samsyn när det gäller att förklara tonförväxlingsmönstren.

The essays main intent is to examine whether there has been a proper implementation of the Council?s directive 1999/70/EG into Swedish law regarding the requirement for measures to prevent the abuse of successive fixed-term employment contracts. To achieve this purpose there is a need for an examination of current law. The essay also has some secondary purposes. One of these secondary purposes is the question of whether the implementation of the Council?s directive 1999/70/EG has lead to a reduction of the workers employment protection, which is closely connected to my main question and the violation case.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

By limiting our horse?s freedom of movement, we restrict their opportunity to forage, which is one of their most important needs. If their need of forage is not fulfilled it can lead to frustration, which might manifest itself in abnormal behaviour, like the oral stereotypies for example crib-biting. It is a held belief that the horse swallows air while crib-biting, which they don?t, and that swallowed air causes colic, and the belief that other horses can copy the behaviour, leads to the use of many methods to prevent the behaviour.

Assessing the emotional state in animals is important in order to establish the quality of their welfare, therefore it is important to investigate under what circumstances animals experience these emotions and to find indicators of their existence. The aim of this thesis was to detect possible behavioural indicators for positive emotions in dogs. These behavioural indicators could be helpful to increase both dogs? and humans? overall well-being in today?s society since they could help e.g. dog owners and caretakers to interpret behaviours displayed by dogs and their intentions so they can respond accordingly.The subjects used were 9 research beagles and each dog participated in three different treatments, assumed to be experienced as positive situations, where communicative interaction was initiated with the dog by engaging in 1) physical contact (P), 2) verbal contact (V) or 3) both physical and verbal contact simultaneously (PV).

Detta examensarbete är utfört på uppdrag från AVL Södertälje Powertrain Engineering AB.Målet med arbetet har varit att utveckla ett styrsystem för ett elektroniskt styrt pneumatiskhydraulisktventilsystem på en encylindrig förbränningsmotor i en testcell. AVL är enoberoende firma som utvecklar drivlinor med förbränningsmotorer samt instrumenterings- ochtestsystem. Ventilsystemet, med ett fungerande styrsystem, ska användas i AVLs utvecklingsochforskningsarbete på förbränningsmotorer.Ventilsystemet,Free Valve Technology, är utvecklat av Cargine Engineering AB och består avelektroniskt styrda pneumatisk-hydrauliska aktivatorer som opererar en motorventil individuellt.Aktivatorernas styrsystem har utvecklats helt iSimulink och implementerats som en integreraddel i det av AVL utvecklade motorstyrsystemet Raptor. Hårdvaran och plattformen är ett rapidprototyping system från dSPACE GmbH. Systemet har visat sig fungera tillfredsställande i entestcellmiljö vid lyfthöjder större än 3 mm och varvtal lägre än 2500 rpm, även underförbränning.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.
