Neuromuskulär återhämtning efter matchspel hos professionella fotbollsspelare

During football games neuromuscular fatigue occuring following eccentric movements such as sprint, jump and run that occur during games. To avoid injury, overtraining and performance decreases, it is important to know when players are recovered. The aim of the pilotstudy was to investigate physiological changes that occur during football matches and if they affect the recovery pattern after several games in professional football players. The method was divided into two sub-studies in which 12 professional footballers, in substudy 1 performed counter movement jump (CMJ) and drop jump (DJ) from 40 cm and fill out a recovery form for muscle soreness 36 hours before, 12-16 and 60-64 hours after 11 different competetive games. Blood samples were taken on the players in connection with one match to examine the activity of muscle enzyme creatine kinase (CK) and lactate dehydrogenase (LDH) of the players.

Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011

Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

Behovet av normalisering av avvikande ungdomar: en kvalitativ studie om eftervård

The society has always tried to get rid of those who do not "fit in". They doesn't follow the normal behaviour and rules and have to be "dismissed". The community has developed different kinds of institutional care for individuals with dysfunctional behaviour. Those institutions are mental hospitals and prisons. Many of these institutions put the individuals in an extreme situation since they loses their independence and freedom.

Målsättning, prognostisering och resursfördelning i en budgetstyrd bank respektive budgetlös bank: En fallstudie av två svenska banker på kontorsnivå

Speaking of budget and budgeting is almost as adding fuel to the fire. The subject evokes a lot of emotions, both positive and negative. Some might consider budgets as a bureaucratic process that won?t lead to any good. Others might find budgets as extremely helpful and necessary in a company?s planning process.

Kan sex veckors plyometrisk träning förbättra maxhastighet, hopphöjd i vertikalhopp samt maxstyrka i knäböj  hos unga män?

Bakgrund: Maxhastighet är en viktig faktor inom många idrotter. Olika faktorer som påverkar maxhastighet är anaerob kapacitet, anaeroba energikällor, muskelstyrka samt förmåga att utveckla power. Plyometrisk träning, där explosiva hopp utförs, har som mål att förbättra stretch-shortening cycle (SSC) och power, vilka är viktiga faktorer vid sprint.Syfte: Syftet med studien var att undersöka hur sex veckors plyometrisk träning påverkade maxhastighet, hopphöjd i vertikalhopp samt maxstyrka i knäböj. Studien undersökte även sambandet mellan maxhastighet och hopphöjd samt maxhastighet och maxstyrka. Den här studien är viktig då ingen tidigare studie till vår vetskap har undersökt hur plyometrisk träning påverkar maxhastighet, hopphöjd och maxstyrka.Metod: Tre test användes för att mäta maxhastighet, hopphöjd samt maxstyrka.

EU:s Fiskeripolitik : På väg mot en rättighetsbaserad förvaltning?

Most of the sea areas within the European Union are overfished and the catches are estimated to be up to five times lager then the amount to achieve a sustainable fishery. In doing so, the management of EU's marine resources comes to be questioned. The purpose of this study was to analyze EU's administration of marine fisheries and to explore which steps that can be undertaken to counteract the negative trend. The questions of the study were: How does the EU administrate today?s marine fishery recourses? And: How can the problem whit overfishing be discouraged? To answer these questions a comparative analyses were used to compare and evaluate administrative systems.

The rescindment of cash management in the Swedish bank industry : a study of how to maintain the customer satisfaction while reducing the overall service offer

Sweden is going through big changes within the bank sector. Increasing card usage, decrease of cash acceptance in the society, an attempt to reduce money laundering, and a possible increase in profitability has lead to the rescindment of cash management among three of the four major banks. This has lead to a big debate in the society, a lot of frustration from customers, and a drop in customer satisfaction for every bank that started the process of removing cash management. The purpose of this study is to find out how the banks could keep their customer satisfaction when removing cash management. When doing the study, the rescindment of cash was a deduction of a part of the service, compared to the normal adding or starting of a service. The study was done through a focus group that was the base of a questionnaire that got answered by 125 respondents.

Energiewendes påverkan på det nordiska kraftsystemet

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

The legacy of the mill : a metal polluted forest soil in Gusum

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.

TILLFÄLLIGA EFFEKTTOPPAR I FJÄRRVÄRMEN : Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

Bedömning, betyg och statistik : En studie om lärares kommunikation och elevers förståelse för bedömning på gymnasiet

Syftet med föreliggande studie är att undersöka hur skolledare, lärare och elever på en gymnasieskola i södra Sverige resonerar om bedömning och betygsättning samt att ta reda på hur betygsfördelningen ser ut vid antagning till och avgång från gymnasiet för årskullen 2008-2011 på den aktuella skolan. Genom insamling av listor med jämförelsetal för de elever som antagits 2008 och över jämförelsetal vid avgång 2011 har diagram över procentuell fördelning av jämförelsetal skapats. Intervjuer med en skolledare, tre gymnasielärare samt tre elever i årskurs tre har gjorts. Min studie visar att det inte finns någon nedskriven bedömningspolicy på den aktuella gymnasieskolan samt att det i relativt stor utsträckning är upp till varje enskild lärare att hitta sätt att förklara bedömning och betygssättning för eleverna. De intervjuade lärarna hade olika strategier för att nå förståelse hos elever för bedömning och betygssättning.

Entrén vid Universitetssjukhuset i Lund : hälsosjukhuset med frånvaro av trivsamhet

Scientific research shows that humans regain their strength when they are spending time in nature. Ulrich, Kaplan & Kaplan, among others, has shown in their research that nature can reduce stress and decrease the after effects of stress. Lund University Hospital, USiL, is a big working place and has a large number of patients. To be a patient often means that you lose control of your daily life which could cause stress. For the personnel high workload can be a stress factor.

Avhopp inom 12-stgsbehandling : En studie om vilka faktorer som finns till klienters avhopp inom 12-stegsbehandling och eventuella skillnader mellan könen.

Syftet med denna studie är att undersöka medvetenhet om uppnåendemål i idrott och hälsa enligt den nationella kursplanen i Lpo94. Vid instiftandet av Lpo94 infördes mål- och kunskapsrelaterad styrning och läroplanen har alltså haft sjutton år att implementeras. Idrott och hälsa är det enda ämnet där pojkar i större utsträckning når högre betyg än flickor. Undersökningen har genomförts med elever i årskurs 9 på sex olika skolor i Sverige. Vi har använt oss av två olika metodansatser, en kvantitativ del i form av enkäter och en kvalitativ del bestående av intervjuer.

Småskalig elproduktion i Arvika

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.
