Hur ser de kemiska principerna för mätning av metabolism med hjälp av indirekt kalorimetri ut? En metodjämförelse mellan Douglas-bag och Oxycon Stationary Pro
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.
Föreligger det en bostadsbubbla i Stockholms Län?
In a historical view, house prices have developed at the same rate as inflation. In the end of the 20th century the prices on the housing market started to differ from the inflation rate, and today the deviation is strong and the real price increase has been very strong.The financial crisis in 2008, which was a result of a subprime mortgage crisis on the American real estate market, has made several agents on the housing market in Sweden question today?s prices. Robert Schiller, an American economist who predicted the mortgage crisis in 2008, claimed during the Nobel Prize ceremony 2013, that Sweden shows signs of a financial bubble ? "I think that people here in Sweden have an illusion that increasing prices is a lasting trend, but that is more suggestive of a bubble".
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader
The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler
This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.
Arbetsprov i fält på ridhästar
Sport horses are widely used for performance in jumping, dressage, endurance etc. To enable comparisons of horses, training facilities, programs or physical status, an exercise test can be used. Exercise tests are also important to increase knowledge about exercise physiology of the horse considering different ways of training to compare training methods or individual qualities, development of an individual or other investigations of equine exercise physiology. Since several investigations are done on standard- and thoroughbred horses but less on sport horses, it is of great importance to get an overview of the investigations done. Most common is to investigate heart rate and lactate concentration.
Tillskottsutfodring av smågrisar under digivningsperioden :
Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.
En uppföljning av analysresultat (serologi och virus) av EAV på seminhingstar i Sverige år 2002 och 2005. :
EVA, Equine Viral Arteritis, was diagnosed for the first time in 1953 in USA. The disease gained international interest in 1984, when there were several outbreaks of abortion at Thoroughbred studs in USA. EAV, Equine Arteritis Virus, is an RNA virus in the Arteriviridae family. There is only one serotype of EAV but several strains and the strains have different virulence. EAV is transmitted in two different ways: by aerosols, or by venereal transmission.
Värdet av företagsrating
Background: Increasingly, companies choose to finance their business with corporate bonds which has resulted in an increased demand on credit ratings. As such the rating agencies have a very important role in the financial markets. Examining the value of a credit-rating can be very interesting for both issuer and investor. Purpose: The purpose of the study is to identify and define the value of rating. Execution: The study is built upon nine interviews with rated and non-rated firms and investors.
Drank som proteinkälla till regnbågslax (Onchorhynchus mykiss) :
The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.
Integrerad hästanläggning : ridhus/stall
Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity.
In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.
Barnkullar och arbetslöshet - Stora barnkullar och möjligheter på arbetsmarknaden
Youth unemployment in Europe is a big problem today. The number of unemployed young people has risen past decades, from 10 % in1980 to over 20 % 2010. The purpose with this thesis is to deal with big cohorts and unemployment rate for young people 20-24 years old in Sweden. I have a look at three different generations, people born:1963-1967 and start working 19871968-1972 and start working 19941988 and start working 2008-2012Did these people from a baby boom face any specific difficulties when entering the labor market 20-24 years later? I have used Easterlin theory in my work and lokked at statistics from SCB (Statsitiska centralbyrån) in Sweden.
Aktiekursförändringar och sökfrekvens på internet
The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..
Seroprevalence and risk factors for bovine brucellosis, salmonellosis and bovine viral diarrhea in urban and peri-urban areas of Kampala, Uganda
Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas.
In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.
Utveckling och konstruktion av växellåda för elektroniskt styrda ställdon
The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.
