Oxygen consumption and carbon dioxide production are usual measurements within the sports and training physiology. The same measurements are also common when it comes to establish the amount of energy that is used during work and to establish the intensity of work. The volume of oxygen that is consumed contra the volume of carbon dioxide that is produced can be used to calculate the metabolic rate within the human body. This calculation shows the percent relationship between carbohydrates and fat in the metabolism. The first accurate method to measure the breathing gases for use in metabolic calculation was established in the early twenty century when the Douglas bag method was introduced.

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

Background and problemThe biggest difference between companies and non-profit organizations are their purposes. Companies? purpose is to generate profit to the shareholders. Non-profit organizations do not have any shareholders and their purpose is to offer service to receivers of benefits.There are a lot of non-profit organizations today and the competition for the donations is rough. Non-profit organizations can influence the publics? decision of who to support by creating a financial reporting that appeal to the public.PurposeThe purpose of this essay is to examine how non-profit goals are measured in non-profit organizations and if there are a practice on the subject.MethodologyWe choose a qualitative approach as we wanted to understand the reality by explaining it with words.

Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.The results of our study indicate that there were clear differences between high-and low-performing students.

This is a product development project which has developed a prototype in order to facilitate for people using mobility devices when they want to buy a larger quantity of groceries. The prototype is a shopping cart composed with the upper part of a walker.Today there are many different types of mobility devices used by elderly and people with physical impairment. According to Myndigheten för samhällsskydd och beredskap (MSB) are accidental falls the most common cause of accidents in Sweden.This project has been using Computer Aided Design (CAD) as a tool to create a visual image of the prototype. The advantage of this is to modify the functionality and performance of the prototype on the computer before the modification takes place in the real model. Using human manikins, the CAD model was rendered in natural surroundings to get as true a picture as possible.

After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce. The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

The objective of this study was to get a better understanding of how the cultivation methods influence the vitality in Prunus avium. The purpose was also to examine if there was any differences in shoot growth and trunk expansion depending on the method of cultivation. To find the answer to this question a literature study and a case study has been done. The literature study concerns the concepts vitality and stress. Different definitions of these concepts are shown and their connection whit establishment is explained. In the background the species Prunus avium, and the four method of cultivation that are included in this case study are described. Measurements of the shoot growth and trunk expansion were made in this study, and as a complement to these methods, a visual estimate of the vitality was made.

AbstractTitle: The effect of caffeine on performance during resistance training ?A systematic overviewAuthor: Amanda Jonsson and Erica BenderSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2015-03-31Background: Products with high content of caffeine has in recent years become popular for optimizing physical performance. Caffeine affects mechanisms in our body which can be beneficial to perform better during exercise, but the theories have not yet been systematically reviewed.Objective: The purpose of this review article, is to examine the acute effect of caffeine intake before strength training on athletic performance with the outcome muscle endurance.Search strategy: A systematic literature search in databases PubMed, Scopus and Cochrane using keywords: ?Caffeine?, ?strength?, ?muscle?, "resistance training", "muscle strength", "strength training", "athletic performance", ?repetitions to failure?, ?muscular endurance? and ?endurance training?.Selection criteria: Healthy subjects, 16-50 years old, with experience in strength training. Studies with a caffeine intake > 5 mg/kg body weight, which participants performed dynamic strength exercises on a weight > 60% of their 1 RM.

Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

During the past twenty years, the Swedish school systems have slowly changed to becomemore and more performance-driven. Private schools have been growing in general and, likeindependent schools and schools managed by municipalities, they profile themselves. Schoolsare becoming more performance and result-oriented, which has changed the roles of teachersin a dramatic way and is in general, still changing.By profiling students based on theirindividual performance, schools are able to help students identify themselves and their owngoals. The process of profiling is a slow one in which some teachers adapt more quickly thanothers, and one that is critical for other teachers to learn in order to keep up with the demandsof society.Schools, like ordinary businesses, are in constant competition with each other to keep up withthe newest and greatest models of teaching and to rank among the best in high achievements.Perhaps the downside of this modern school structure is that it is often difficult to have aschool where both school management and teachers see eye to eye. School management must heavily focus on the school?s results as a whole.
