This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

Utvecklingen inom förmedling av bostäder har gått snabbt sedan internet blev en del av vårvardag. Idag vänder vi oss online för att hitta vår nya bostad och detta ger möjligheten attfölja bostadsmarknaden på ett helt nytt sätt. Denna uppsats undersöker relationen mellanSveriges bostadsköpares sökbeteende på Sveriges utan tvekan största bostadssöksajt Hemnetoch Riksbankens räntebesked.Genom att analysera det totala antalet sökningar gjorda på bostadsrätter, hus och fritidshus vidav Riksbanken rapporterade räntehöjningar, räntesänkningar samt en lämnad oförändradreporänta försöker författarna se om sökbeteendet ändras. Sökbeteendet fyller funktionen aven ny möjlig indikator för efterfrågan på den Svenska bostadsmarknaden. Den statistik somundersöks sträcker sig från tidsperioden april 2011 till april 2013.Resultatet av studien visar att Riksbankens räntebeslut, oavsett karaktär, inte ger någon effektpå antalet sökningar.

Vid införandet av 3:12-reglerna var lagstiftarens syfte att förhindra inkomstomvandling för delägare i fåmansföretag. På senare tid har synsättet förändrats och man fokuserar sedan reformen 2006 mer på att stimulera företagande och förenkla regelverket. År 2006 infördes förenklingsregeln för att underlätta tillämpningen av gränsbeloppsberäkningen. Förenk­lingsregeln innebär en förenklad beräkning av gränsbeloppet som inte tar hänsyn till företagets verksamhet. Det har i studier visats att förenklingsregelns tillämpning utnyttjas i skatteplaneringssyfte av delägare i fåmansföretag utan direkt aktivitet.Syftet med denna uppsats är att utreda förenklingsregeln och huruvida någon begränsning bör införas i dess tillämpning för att undvika inkomstomvandling.

Joint-related diseases including hip dysplasia (HD) and elbow arthritis (ED) can in advance cases lead to that the dog has to be put down, and these diseases are also the cause to expensive veterinary treatments of many large breeds, including Labrador Retrievers. The aim of this study was to make a follow-up study on the 271 Labradors, who previously participated in a study on the effect of nutrition and exercise on hip and elbow status in a birth cohort born year 2000. That study investigated the relationship between nutrition, exercise, and HD and ED. A follow up study on the same dogs at 5-6 years of age investigated the clinical effects of the radiological hip and elbow status at 1 years of age and if was effected by body condition score. This study took place in 2011-2012 and 187 Labrador retrievers participated.

Fermented liquid feed is well known for its health promoting effects on piglets. High levels of lactic acid are desired in the feed together with low levels of acetic acid and certain biogenic amines. Limits for acetic acid have been suggested to be 30-40 mmol/kg to avoid a decreased palatability of the feed; however, few studies have been performed. The purpose of this trial was therefore to examine which levels of lactic acid and acetic acid that can be accepted in a fermented feed without affecting the feed intake and thus the weight gain of the pig. A total of 60 pigs (Yorkshire/ Hampshire) were used in a trial during two weeks, between 9-11 weeks of age.

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.

Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

Tidigare forskning har visat att barn med typisk utveckling går från en visuell strategi till en fonologisk. Huruvida denna utveckling sker hos personer med utvecklingsstörning är oklart. De flesta forskare är överens om att dessa personer har en nedsättning i den fonologiska loopen. Om denna nedsättning beror på strukturella avvikelser eller utvecklingsförsening är forskarna inte eniga om. Det är även oklart var en eventuell strukturnedsättning skulle sitta.

Scientific research shows that humans regain their strength when they are spending time in nature. Ulrich, Kaplan & Kaplan, among others, has shown in their research that nature can reduce stress and decrease the after effects of stress. Lund University Hospital, USiL, is a big working place and has a large number of patients. To be a patient often means that you lose control of your daily life which could cause stress. For the personnel high workload can be a stress factor.

Syftet med denna studie var att undersöka vilka samband det finns mellan värderingar, föreställningar och normer kring miljön till agerande för ekologisk hållbarhet i det vardagliga livet. Vår hypotes var att det finns samband mellan affekter kring miljöns framtid och agerande till hållbar utveckling. För att söka svar på syftet och bekräfta hypotesen har enkäter med frågor gällande individens värderingar, föreställningar och normer om miljön samt frågor om miljömässigt agerande skickats ut via e-post till 119 deltagare i åldern 23-65 år. Svarsfrekvensen var på 59 procent. Resultatet visade att det fanns ett flertal starka samband mellan miljömässiga värderingar, föreställningar och normer till individens agerande och hypotesen om att det fanns samband mellan affekter och agerande för hållbar utveckling verifierades.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Aim: The aim of this study was to examine a way to measure students? knowledge development by using a self-made measure instrument based on William Doll?s postmodern curriculum.Question: Is it suitable to use an self-made measure instrument based on William Doll?s post-modern curriculum theory to measure development of knowledge?Methods: The study was based on process-hermeneutics and was focused on analysingcollege students? written and oral reflective thoughts. The data was collected over three lessons, where six students? written reflective thoughts were handed in. An observation was carried out each lesson for an extra control of validity.

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.
