Effekterna av praktisk ocklusionsträning periodiserat med ett traditionellt styrketräningsprogram på anaerob prestation

Background: Practical blood flow restriction (pBFR) combined with resistance training has been proven to facilitate muscle strength despite training at low intensity. However, research investigating the effects of long-term pBFR-training and its periodization with strength training (ST) at a higher intensity is lacking, as well as the effects of occlusion training on blood lactate levels (BLL) over time.Purpose: To compare the effects of 2 weeks of pBFR training followed by 2 weeks of ST (BFR-ST) with 2 weeks of ST followed by 2 weeks of pBFR training (ST-BFR) on anaerobic performace and BLL.Method: 5 adults (age 23 ± 2 years) with a minimum of 1 year of ST experience were recruited and randomized into BFR-ST (n=2) or ST-BFR (n=3). Anaerobic performance was measured using a 30-s Wingate-test and BLL samples were collected <1 and 5 minutes post-Wingate. Data and samples were collected before the intervention and after the 2 protocols.Results: No differences were seen between groups in anaerobic output or BLL after 4 weeks of training (p>0,1 for all values). A decrease in time to peak power (tPP) were seen in both groups with an advantage for BFR-ST (-37 ± 8 %) over ST-BFR (-27 ± 22 %).

Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Vanvårdens inverkan på nötkreaturs välfärd och hälsa

Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.

Analys av sorptiv kylning i industri- och kontorsbyggnader

Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.

Hylasmotivet hos Apollonios Rhodios och Theokritos

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

This paper includes astudy of the mutual fund market investors during a selected timeperiod. The reader is given a descriptive picture of how people in different age groups have  acted  in  conjunction  with  the  last  major  financial  crisis.  It  has  been  studied whether people in the different age categories have saved,purchased or sold during this time  period  based  on  theories  and  analytic  material  from  one  of  the  largest  fund operators in Sweden. The result enlightens people?s activity and risk appetite in relation to the fund market. The essay results in an explanation of the underlying cause of the behavior        of         the         people         in         the         different         age         categories.The paper assumes that the market is cyclical and that more crises will occur in the future.

Utveckling och konstruktion av dämpare och låssystem för vågkraftverk

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

RESEBYRÅERS KONKURRENSFÖRDEL UTIFRÅN SEXHÖRNINGEN : Fritidsresor och Ving, vilken resebyrå väljer kunden utefter positioneringen i sexhörningen?

Resebyråerna växer i allt stadigare takt, allt eftersom fler människor väljer att färdas med flyg på grund av den effektiva globaliseringen som pågår världen om. Ving och Fritidsresor är två resebyråer som följt med utvecklingen sedan mitten av 1900-talet och har nu blivit två av de ledande resebyråerna i Sverige.Därmed är det intressant att göra en jämförelse mellan dessa och se om det finns några påtagliga likheter eller skillnader. Detta arbete kommer att beröra Ving och Fritidsresors konkurrens för- och nackdelar ur ett kundperspektiv. Det har tagits fram med hjälp av konkurrensmedelsmixen, sexhörningen som består av följande sex hörn, geografi, sortiment, kommunikation, människor, service och pris. För att ta reda på hur betydelsefulla hörnen är för kunden och hur de upplever att Ving och Fritidsresor möter deras behov.Undersökningen har gjorts med hjälp av en kombinerad enkätundersökning av kvantitativ- och kvalitativa frågor som senare har jämförts med aktuell teori.

Mikrosimulering för analys av Mästergatans förlängning i Enköping

Two of the main approach roads into the city of Enköping are Salavägen and Stockholmsvägen. They are connected to each other through the street Bangårdsgatan in the roundabout Salatullen and crossing Fannakorset, respectively. These crossings are from time to time heavily loaded, which is why the municipality plan for a new street in parallel to Bangårdsgatan. The traffic will then be spread out and is thereby reducing the density. The new street is actually an extension of the existing Mästergatan, a side street to Salavägen, to the east and connecting it to Stockholmsvägen or a street nearby.The purpose of this Master thesis is to show how the new street can be drawn in order to discharge the traffic in the area between the roundabout Salatullen and the crossing Fannakorset.

KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?

Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

Energibolagens framtida datainsamling

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations.
