The purpose of this study was to evaluate if there is a difference in maximal aerobic power (VO2-max) between walking with poles and without poles. Thirty-four healthy women between the ages of 22 and 60 years participated. They were randomised into two groups, seventeen individuals walked with poles and seventeen walked without poles. Both groups walked four kilometres three times a week, for eight weeks. Each completed a submaximal cycle ergometertest before and after the exercise period.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.

The general consensus is that the gap between the Swedish variable mortgage rate and the repo rate has increased over the last years. Although the Riksbank in recent times has cut its base rate, many banks have chosen either to leave the interest rate on variable mortgages unchanged, or they did reduce it but by less points than the reduction in the repo rate. The linear relationship between the repo rate and the variable mortgage rate has changed over the last decade and the mortgage margins these days are relatively high. This can somewhat be explained by the new rules introduced in the bank sector requiring banks to increase liquidity and equity. Since mortgage loans play an important role in banks? lending business it is of interest to gain knowledge in whether a repo rate reduction latterly has generated a limited affect on the banks lending rates..

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.

Abstract:In previous experiments with the bacterium Ideonella dechloratans a probable sequencecoding for a cytochrome c protein (cyt c) was observed, the sequence is assumed to have afunction in the bacterial respiratory chain. Detection attempts have been made to try to findthis protein, but have not succeeded. The purpose of this project is to detect the expressionof mRNA associated with the cytochrome c. And if it is detected, it will also be investigated ifthere is any difference in expression of the mRNA due to aerobic or anaerobic environment.Total RNA was purified from cultures grown under aerobic and anaerobic conditions. cDNAwas then synthesized using reverse transcriptase and subsequently amplified with thespecific primers in a qRT-PCR.qRT-PCR testing showed a distinct amplification of primer product, confirming that I.dechloratans expresses mRNA coding for the cyt c protein.

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

This paper presents empirical evidence on the determinants of interest rate swap spreads in Sweden during the period 1999-2003. The results suggest that the spread between STIBOR and the general collateral repo rate is positively related to shorter maturity swap spreads. The risk premium associated with commercial bonds is positively related to swap spreads of all maturities. A negative relationship is observed between the term structure of interest rates and swap spreads. The short-term interest rate is positively related to spreads with shorter maturities.

Man spends most part of the day at work and is therefore influenced by it?s ambience. That?s why it?s important that the environment at work is health promoting and can function as a supportive environment. The purpose of this study was to describe job satisfaction among employees and to analyse a possible connection between job satisfaction and employees experiences of SOC.

Teorin utgörs av den effektiva marknadshypotesen, där vi utgår från den semistarka formen av marknadseffektivitet, aktiers räntekänslighet samt investerares beteende vid makroekonomiska nyheter. Undersökningen visar att det finns avvikande avkastning på Stockholmsbörsen vid förändringar av The Federal Funds Rate. Resultatet varierar dock mellan A- och O-listan..

Good physical, psychological and social health is pursued both at work and at home. There is no current research into the health of ski instructors despite the physically demanding nature of skiing and high injury rate. The purpose of this study is to map out ski instructors physical and psychological health and see if there are common injuries amongst them. This study is a descriptive and correlating study including a survey of ten questions with self reported data from the instructors. Five ski schools from Sweden participated in the study and 86 surveys got sent out to the ski school directors.The result from this study shows that ski instructor´s physical, physiological, well being at work, stress level and self efficacy is good.

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use aerobic pathways in the metabolism.

The spontaneous blink rate is found to be a non-invasive but functional, reliable and useful way to monitor central dopaminergic activity. Dopamine is associated with a range of functions such as reward, motivation and learning. It plays an important role in goal-directed behavior and in maintaining a behavior once a task is learned. As far as the author knows, there are today no publications that discuss the topic regarding the possible link between training and spontaneous blink rate in dogs. Therefore, eight privately owned dogs were included in this study to determine if there was a significant difference in the spontaneous blink rate before and after the process of learning a task.
