Kan kombinationsbehandling med liotyronin och levotyroxin ge positiva effekter hos patienter med hypotyreos?
Bakgrund: Sköldkörteln är en endokrin körtel som tillverkar två viktiga hormon som påverkar många olika organ, tyroxin (T4) och trijodtyronin (T3) som är det mest aktiva. Det tillstånd då det bildas för lite sköldkörtelhormon jämfört med vad kroppen kräver kallas hypotyreos och hypotyreos kan vara svår att känna igen på grund av en skiftande symptombild. Syntetiskt T4, levotyroxin, är förstahandsval vid behandling. Trots tillräcklig dosering av levotyroxin, har patienter visats ha minskat psykologisk välbefinnande och minskad neurokognitiv funktion. I enstaka fall, när patienten inte mår bra trots att proverna ser bra ut, kan tillägg av L-T3 prövas.
Kontokortsbaserade betalningssystem på Internet
Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

Marknadsanpassning : hot eller möjlighet?
Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.
Förstå kundens bruksvärde
Abstract?Understand the customers value in use ? A multiple case study of three industrial companies? or ?Förstå kundens bruksvärde ? En multipel fallstudie av tre industriella företag? brings out the problem that it is easy to assume, what the value is for the customer.The questions asked for this thesis are:? How does the companies in focus, gather information about what effects the customers value in use?? How do the companies use this information in their business?The purpose is to examine how some industrial companies gather information about the customer?s value in use, on the bases from the five activities from Porter and how they can use this information.Three semi structured interviews were made for this investigation, with representatives from Atlas Copco Rock Drills, IL Recycling and Johnson Pump.The conclusions are that to gather information about the customers value in use, the company must work close with the customer. This information helps the company to improve their products, services and their relationships..
Direkta effekter av insekticiden deltametrin på zooplankton och bottenfauna : en fältstudie av bieffekter av insekticidinducerad eliminering av signalkräfta på Gotland
Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Vilka faktorer påverkar företags kassahållning?: En studie av svenska börsbolag 1999 - 2009
This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.
Att styra eller leda - En studie av rollfördelningen mellan styrelse och VD i strategiutvecklingen i svenska börsnoterade företag
Who has the ownership of a company´s long-term strategy, and who should have it? Is it the board of directors or the senior management? Swedish law and regulations seemingly point in one direction, whereas the findings of studying the relationship between CEO and chairman of the board in eleven Swedish listed large- and mid-cap companies, point the other way. In a majority of the companies the senior management have the ownership of the long term strategy whilst the board of directors merely hold a control function. The possible effects on the companies managed as well as the rules and regulations they are managed according to, are analyzed..
Kan ett ökat intag av omega-3- fettsyror påverka testosteronnivåer hos kvinnor med PCOS?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.
Scalable Services over DAB and DVB-T from a Receiver Point of View
TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.
Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania
More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations.
Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist.
There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.
