Statistisk kartläggning av dimma längs E4:an mellan Helsingborg och Jönköping

Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Traumatiska skador hos ishockeyspelare i Sverige : en registerstudie

AimThe aim of this study was to map the injury panorama of traumatic injuries related to ice hockey in Sweden 2006-2011. In addition to that the aim was to compare whether there were any gender differences regarding traumatic ice hockey injuries. MethodThe present study was based on data from the Folksam insurance company between 2006 and 2011. The population consisted of ice hockey players in a club affiliated to the Swedish Ice Hockey Federation and that had sustained a traumatic injury related to ice hockey that resulted in medical care and then was reported to Folksam. The results are presented with descriptive statistics such as mean and standard deviation, median range and frequencies. ResultsThe head was the most common injury localization followed by the upper extremity where the shoulder accounted for a high number of injuries. Fracture was the most common type of injury for both male and female players.

This thesis was written by order of Rud Pedersen Public Affairs Company, a PR- consultancy firm located in Gothenburg. The assignment was to investigate social media in Pr- activities. The thesis is formed by three main categories:? What is social media?? Who are using social media?? How can you use social media in public relations?The information which is being presented in this thesis is based on academic reports, interviews and research on social media blogs and lectures. It is a qualitative approach since the purpose is to get a deeper understanding for the subject in question.

Utveckling och tillämpning av modeller förkvantifiering av de ekonomiska konsekvensernaav ökad förbrukningsflexibilitet inom eldistribution

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

Free cow traffic in automatic milking systems (AMS) : a case study on nine commercial dairy farms in Sweden

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer

Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.

Utvärdering av rörelsemönster hos öring (Salmo trutta) utifrån otolitmikrokemi

The classic view of trout (Salmo trutta) life history is that trout begins its life in freshwater, migrates to the ocean after about 1-4 years and then returns to freshwater to spawn. As trout fry have been caught at the mouth of the River Emån, near the Baltic Sea, researchers have speculated that some trout emigrate during their first year of life. The purpose of this study was to describe the variation in the length of time trout reside in freshwater before they migrate to the ocean for the first time. Another purpose was to investigate whether it was possible to discern where and how long the fish spent in freshwater and saltwater during different parts of their lives. Between 2007 and 2009, 23 adult trout were captured in the River Emån in southeastern Sweden.

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. At times when the electricity supply system is highly loaded, electricity is more expensive.

Fruktosamin som markör för diabetes mellitus hos katt :

Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.

Calf health before and after change in housing system ? isolated barn vs. hutches

Calf health is of importance both from a financial perspective and from an animal welfare point of view. Housing system and environment are factors affecting the calves? health. The objective of this project was to make a review of literature on calf health and housing and to perform an observational study on calf health at Nötcenter Viken, Research Dairy Farm, Lantmännen Sweden that changed calf housing system; from a traditional indoor system (Group IN) to outdoor hutches (Group OUT). It was only the housing system that was changed; the routines and feed were the same in both systems.

Skyldigheten att skydda : Utvecklingen av R2P ur ett folkrättsligt perspektiv

The debate regarding the relationship between state sovereignty and the protection of the hu-man rights was at its peak during the 1990?s. Never again the world wanted to witness the atrocities committed in Rwanda, but at the same time some states argued in favor of a strict interpretation of the principle of state sovereignty and non-intervention. In 2001, ICISS was created ? a commission with the aim to find consensus in the question of how the world should respond to mass atrocities committed by a state against their own people.

Outsourcing en fråga om överlevnad?

En väsentlig fråga hos textil- och klädindustrin (TK-industrin) har alltid varit om de skall utföra arbetet själv eller köpa in arbetet. TK-industrin använder sig av outsourcing på grund av att de inte själva klarar av att sköta verksamheten på ett tillfredställande sätt eller att man helt enkelt väljer att inte utföra arbetet själv. De främsta motiven till att outsourca är att företaget vill uppnå kostnadsbesparingar och fokusera på kärnverksamheten. TK-industrin är unik och frågan är om det främsta motivet är kostnadsbesparingar eller finns det andra motiv såsom fokus på kärnverksamhet, flexibilitet eller bättre kvalité som är huvudmotivet till outsourcing.Vårt syfte med uppsatsen är att genom intervjuer undersöka varför TK-industrin använder sig av outsourcing och vilka effekter det ger. Uppsatsen syftar även till att ta reda på hur specialiserade logistikföretag kan förbättra för företag inom TK-industrin.

Med brödfödan som drivkraft : En studie om att byta olja mot biodrivmedel i ett globalt perspektiv

Av två anledningar anses det som mycket viktigt att bryta beroendet av olja, naturgas och kol. Den första anledningen är de uppmärksammade klimatförändringarna. Förbränning av fossila bränslen anges idag som huvudorsak till växthuseffekten. Den andra mindre uppmärksammade orsaken är att oljan och naturgasen snart inte räcker till för att föda en allt energihungrigare värld. Utvinningen ser dessutom ut att ha nåt sin kulmen.

Halvledare för höga strömmar i fordon

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
