Säkerställning av kommunal bredbandsutbyggnad
The purpose with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.
Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper
The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..
Preoperativ SWAL-QOL och sväljningsfunktion hos Parkinson patienter selekterade till Deep Brain Stimulation
AbstractObjectivePatients with Parkinson?s disease often have symptoms of dysphagia. These swallowingproblems have consequences for quality of life as well for the physical wellbeing of thepatients. AimThe aim of this study was to describe and correlate Swallowing Quality of Life (SWAL-QOL)scores, self-assessment of swallowing function using a visual analogue scale and the resultsfrom a fiber endoscopic evaluation of swallowing function in patients who had been selectedfor Deep Brain Stimulation in caudal zona incerta. A secondary aim was to correlate diseaseduration with results from SWAL-QOL and the fiber endoscopic evaluation of swallowingfunction.MethodTen male Parkinson?s patients (age 45-69 yrs, median 61.5 yrs) who were selected for DeepBrain Stimulation completing the Swallowing Quality of life form, as well as rating theirswallowing function using a visual analogue scale and undergoing a fiber endoscopicevaluation of their swallowing function. ResultsThe median total SWAL-QOL score was 94% while the mean was 91%.
Göta älvbron, övervakning med optisk fiber : Ekonomisk analys
The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.
Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :
Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis.
Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.
En analys av foderkostnader i mjölkproduktion
Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

I vilken utsträckning kan hästar enbart utfodras med grovfoder?
Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.
Konceptarbete om skidbalk i kompositutförande till BVS10
This thesis has been performed at BAE Systems Hägglunds, which is located in Örnsköldsvik. Hägglunds has a wide background of engineering, where they have manufactured all from airplanes to lifting cranes. Currently they only produce track vehicles at Hägglunds, where they manufacture the CV90 and BVS10 models. This thesis concerns the BVS10 which is an all-terrain-vehicle. The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.

Flygteknik : Konceptstudie av ett obemannat flygplan
Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.
Kläder i hampa - ett miljövänligt alternativ/komplement till bomull?
Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.
Är fiberarmerad sprutbetong motiverad ur bärighetssynpunkt? : En jämförelse med traditionell släntning och jordspikning
This thesis is written on behalf of Skanska, Väg- och Anläggning Stockholm Mälardalen, vid Nya Karolinska Sjukhuset i Solna, NKS. The report has resulted in recommendations for the method of soil stabilizations of soil nailing, excavation of slope and fiber reinforced shotcrete, which is the most suitable method from a safety and a cost point at the NKS.The aim of this thesis was to investigate whether fiber reinforced shotcrete increases slope stability, with the focus being on the total stability. The main goal was to investigate which method of soil stabilization is the most suitable for the slopes that are analyzed in this report. Through studying literature, the authors have gained an understanding about the theoretical background for the given problem. Through calculations and analyses of the slopes, safety factors have been acquired.
Foderstatens fiber- och stärkelsehalt i svensk mjölkproduktion : en fältstudie
Det finns en önskan om att finna bättre parametrar för att kunna förutse hur fodret fungerar i kon. Svenska Foder AB redovisar därför måtten smältbar fiber, ((NDF* EFD)+pektin) och fiberkvot, ((NDF* EFD)+pektin)/ stärkelse, i sina kraftfoder. Genom att välja olika sorters kolhydrater kommer foderstaten och därmed djuren att påverkas på olika sätt. En stor del av kornas foderstater består av kolhydrater. Arbetet har försökt att belysa om det finns en skill-nad i produktion och hälsa på gårdar där man har en hög andel smältbar fiber i foderstaten jämfört med gårdar som har en hög andel stärkelse i foderstaten.
Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
