Samband mellan testosteron, DHEAS, kroppskomposition och fysiska kapaciteter hos unga kvinnliga fotbollsspelare
Testosterone is a steroid and anabolic hormone found in all mammals. Previous research indicates that testosterone levels correlates with physical capacities related to physical performance. However, these studies refers only to men and boys. The aim of present study was therefore to investigate the potential relationship between body composition, strength, power and endurance capabilities in relation to blood levels of testosterone and DHEAS in young female football players. Seventeen female elite football (age: 15,4 ± 0,6, body mass: 57,2 ± 7,4kg, height 1,65 ±0,04m) players volunteered for the study.
Faktorer som stör patientens sömn under sjukhusvistelsen samt sjuksköterskans omvårdnadsåtgärder för att främja sömnen : En litteraturstudie
Background: Sleeping is a condition that is necessary for all people because the body isgiven time to recover. Studies have shown that patients found it difficult to sleep during thehospital stay and it turned out to be several factors that disturbed the sleep during the night.The nurse should note the patient?s need for sleep and take into account environmental andother sleep disturbances to be able to implement nursing interventions. Purpose: The purposeof this study was to elucidate the factors that interfere with patient?s sleep duringhospitalization and nursing care to promote the patient?s ability to sleep.
Solcellsdrivning av distribuerade inbyggda system
The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.
Generationsskräpsamling med explicit kontroll av hårdvarucache
This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..
Utredning av fastighetsel i ett äldre och ett ombyggt flerbostadshus i Gävle
The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..
Utvärdering av inomhuslokalisering med Bluetooth Low Energy
Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.
Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor
This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
Databaser i molnet : En prestanda utvärdering
AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.
"Lärarna säger att man ska vara tyst och äta" : en kvalitativ studie av den pedagogiska lunchen
The title of the paper aims at a comment by one of the students during an interview. It reflects how most of the students experience the lunches in a specific school where the investigation is made. The question of pedagogical lunches has always interested me. Here I have used a method called the Grounded theory. I carried out a qualitative investigation with a number of methods such as interviews and participating observations.
Inflation! : Är performance lika med konst?
Till min uppsats valde jag att koncentrera mig på två verk, Post Office och Factotum, av författaren Charles Bukowski (1920-1994). Huvudpersonen i båda romanerna kallas Henry Chinaski och är en mycket komplicerad karaktär. För att kunna analysera dennes självdestruktivitet samt syn på kvinnor och arbete anlade jag ett mansforskningsperspektiv, något som jag också utförligt beskriver..
STRESS med stora bokstäver bland små och stora människor
This essay deals with the issue of children and stress, and the impact that stress can have on children. The purpose has been to explore how I, in my role as teacher, can prevent children from developing stress in preschool, and how I can prevent stress to develop inside of my own department. My essay is structured as follows: First, I describe my practical work with children. Then I analyze some research literature on stress, and finally I reflect over what I have described earlier and try to connect the practical with the theoretical.In the practical part of this essay I describe the various events that I have observed during my work in preschool, where I have seen how stress can affect both children and teachers. Then I describe how the increasing size of children?s groups can create stress because of the noisy environment of the department.
Giraffens blodtrycksreglering
Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.
Kulturmiljövärden utan synintryck, en studie med synskadade
This graduate thesis takes its hold in an idea that many values, in cultural heritage environments, other than the onesthat can be seen with the eyes are as important for the experience of the environment as the visual ones; however theenvironments are usually defined by values that can be experienced visually!Interviews were held with four visually impaired persons. This to get a better understanding for how big part othersense modalities play in the experience of the cultural heritage environments. Questions were asked about what thevisually impaired especially value in cultural heritage environments and what is of value for preservation. Also whatcan be done to make the environments more impressive for them, how they experience the material part of theheritage, architecture, shape and color and with what senses they primarily remember. Furthermore the thesis aims todraw attention to how value definitions made by the conservation field affects the experience of the environmentsand therefore the accessibility for visually impaired.
En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö
The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.
GMO Food Products - The issue of marketing and selling them in Europe.
Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.
