Analys av försäsongsträningen hos ett svenskt damfotbollslag på elitnivå

Syftet med denna studie var att analysera vilken del av försäsongsträningens två cykler som påverkade styrka och explosivitet i nedre extremitet, accelerationsförmåga, agility och anaerob uthållighet genom att sammanställa dessa egenskaper hos kvinnliga elitfotbollsspelare, för att därefter kunna utvärdera om försäsongsträningen förbättrade dessa egenskaper.Tester som kunnat påvisa viktiga och avgörande fysiska kvalitéer hos elitfotbollsspelarevaldes ut och dessa genomfördes vid tre tillfällen; före, under och efter försäsongsträningen. Testerna var; knäböj, vertikalhopp, 15 m sprint, T-test och YO-YO Intermittent Återhämtningstest (YO-YO IÅ).Studien innefattade 24 damfotbollsspelare på elitnivå från alla spelarpositioner.Till den andra testomgången observerades en signifikant förbättring av styrka, agility och anaerob uthållighet. Vid de andra testerna observerades ingen skillnad.Första delen av försäsongsträningen utvecklade till viss del spelarna åt rätt håll genom en förbättring av styrkan i nedre extremiteten. Den signifikanta förbättringen i agility och anaerob uthållighet kom lite för tidigt, det vill säga under den första cykeln avförsäsongsträningen, vilket hade varit mer önskvärt efter den andra cykeln. Detta innebär attandra viktiga egenskaper kan ha försummats..

Anaerob nedbrytning av TNT : Ett bioreaktorförsök på Vingåkersverken

A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from laboratory studies could be repeated in a full scale reactor. The goal of the project was to optimize the reactor to such a degree that it could be used to handle the waste produced at Vingåkersverken and also that this technique could be applied for remediation of contaminated soils. Unfortunately the samples taken during the full scale field test were destroyed by the shipping company and no analysis was possible. A later attempt by the Biorex research group has also been unsuccessful to reduce the amount of TNT using the bioreactor.

Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

EU och folkomröstningarna En undersökning om de europeiska ländernas skiftande karaktär och hur dess väljare agerat i förhållande till detta

33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

GNSS-Styrning : Information för platschefer

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

Miljödammars funktion som kväve- och fosforfälla samt som bevattningsdamm i Sölvesborgs kommun

A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

Förbättrar en kvalitetssäkring skördarens dimensionsmätning?

In this study it was investigated if the adoption of a new routine for quality control could improve the precision of the dimension measurement obtained by harvesters. Data was collected from three different harvesters. First, a reference data set was collected before the new procedures had been incorporated, and then when the new methodology was implemented another data set was collected by the harvester operators, allowing the two data set to be compered. The results indicated that following the implementation of the new procedures, the reliability and the precision of the measurements has increased. All harvesters included in the study had improved regarding most of the controlled factors such as standard deviation, systematic difference and hit rate within ± 2 cm for length and ± 4 mm for diameter..

Korrelationer mellan agility och unilateral och bilateral effektutveckling hos kvinnliga fotbollsspelare

Bakgrund: Unilateral benträning är ett relativt outforskat område inom träningsvetenskapen. Traditionellt genomförs fysträning för intermittenta idrotter bilateralt, trots att idrottens rörelser sker unilateralt. Det finns många studier som behandlar samband mellan agility och effektutveckling, men få som har undersökt skillnaden mellan unilateral och bilateral effektutveckling sett till agility.Syfte: Syftet med denna studie var att undersöka om unilateral effektutveckling har en starkare korrelation med agility än vad bilateral effektutveckling och agility har hos kvinnliga fotbollsspelare i division 2.Metod: Kvinnliga fotbollsspelare (n=13, ålder 23 ± 4 år) utförde vertikalhopp med tilläggsbelastning på båda benen, vänster ben och höger ben på 20 kg, 30 kg, 40 kg samt för båda benen på 50 kg och T-test och Pro agility test. Effektutveckling i förhållande till kroppsvikten på båda benen (PBbw), vänster ben (PVbw) och höger ben (PHbw) analyserades och korrelerades sedan mot T-test (Ttest) och Pro agility test (Proagility).Resultat: Signifikanta korrelationer hittades mellan agility och både vänster unilateral (PVbw-Ttest, r = -0,578) och bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) effektutveckling, där korrelationen bilateralt var starkast. Ingen signifikant korrelation hittades mellan höger ben och agility.Konklusion: Bilateral effektutveckling hade en starkare korrelation med agility än vad unilateral effektutveckling och agility hade hos kvinnliga fotbollsspelare i division 2..

Påverkan på TED- spread under den nuvarande finansiella krisen

Dynamiskt DNA : - En tjänsteutveckling av DNA-test

Något av det svåraste som kan drabba oss är när en vän, familjemedlem eller släkting går bort eller drabbas av en sjukdom. Döden är en naturlig del av livet, men känns detta till trots jobbig eller rent av orättvis då den slår till. I de flesta fall är döden även resultatet av en sjukdom, en sjukdom som med dagens kunskap kanske hade varit möjlig att undvika. Eftersom döden i många fall har varit lite av ett mysterium genom människans historia har vi också lärt oss att rädas den. Nu, när den tekniska utvecklingen öppnar nya dörrar för att i förväg göra riskbedömningar av möjliga sjukdomar som kan drabba individen, så drar sig många undan.

Beslutstödssystem för trafikplanering : från sparad tid till framtid

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Transporttider för vatten i närområdet till en vattentäkt : spårämnesförsök i en isälvsavlagring

When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.
