Granskning av tilllgänglighetsmått i små bostäder : För att öka och underlätta projekteringen av ungdoms- och studentlägenheter

Bostadsbristen för unga växer i takt med att fler byggherrar avstår från att bygga små lägenheter, då rådande lagar gör det svårt att på ett gynnsamt sätt producera kostnads- och yteffektiva bostäder. Bostäder har i dag krav på sig från kommuner och beställare att uppfylla svensk standard. Däri har handikapporganisationer drivit fram tillgänglighetskrav som medför att alla nyproducerade bostäder är tillgänglighetsanpassade.Genom att ifrågasätta svensk funktionshinderspolitik i samband med bostadsbyggande har detta examensarbete som mål att hitta lösningar för att öka nyproduktionen av små bostäder. Granskningen resulterade i ett förslag till en ny standard för ungdoms- och studentbostäder vilken underlättar vid projektering av mindre enskilda bostadslägenheter..

Flygplansavisningens miljöpåverkan vid svenska flygplatser

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Emotional Availability Scales -Therapy : Att mäta emotionell tillgänglighet mellan terapeut och patient i en psykoterapi  

Syftet med uppsatsen var att utarbeta och prova EAS-T (Emotional Availability Scales ? Therapy), en manual för att mäta emotionell tillgänglighet mellan terapeut och patient i en psykoterapi. Arbetet ingår som en del i projektet LURIPP (Linköping University Relational and Interpersonal Psychotherapy Project).Våra frågeställningar var:* Kan man mäta den emotionella tillgängligheten i en psykoterapi med EAS-T?* Finns det någon korrelation mellan EAS-T och patientskattade processmått? För att svara på frågorna har vi arbetat med att modifiera EAS (Emotional Availability Scales), ett instrument som används för att mäta kvalitén på relationen mellan förälder och barn, så att den ska passa terapeut-patient-relationen. Vi har skattat videoinspelade sessioner av IPT-terapier (interpersonell psykoterapi) med hjälp av detta instrument.

Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Effects of treatment with PiNO (Pulsed Inhaled Nitric-Oxide) on the metabolism in colic horses undergoing abdominal surgery.

The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.

Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

Lärare och digitala verktyg i matematikundervisningen : En kvantitativ studie om lärares inställning och kompetens kring användningen av digitala verktyg i årskurserna F-3

The purpose of this study is to examine in what extent primary school teachers, teaching children in the age of 6 to 9, choose to use digital tools in their teaching of mathematics. I also want to examine what these teachers think, in terms of advantages and disadvantages, about using digital tools on their mathematics lessons. Finally I want to examine what skills they possess about digital tools.I am using a quantitative method to collect my data. The quantitative survey consisted of a questionnaire survey of ten questions that 38 primary school teachers have answered.The results of my study show that the teachers to some extent use digital tools when they teach mathematics and that the availability of various digital tools are generally good. But it turns out that the availability of tools is not a guarantee that they are used in teaching of mathematics.

?Out of sight, out of mind? : En studie av svenska bokbloggares inställningar till e-boken

There are experiential products that through a digital transformation wholly or partially have taken new place in our everyday lives. Just a few years ago, we had music on CDs, movies on tape and books in bookshelves. In Sweden, we are now facing a transformation when the e-book begins to take place alongside the printed book.This paper focuses on what values play a role in the attitude towards ebooks among a selected group of Swedish book bloggers. A qualitative content analysis was performed on blog posts concerning the ebook from twelve different Swedish book blogs. The posts were then coded into categories and values.

Mobil kommunikation och högre tillgänglighet vid längre elavbrott : Exemplet stormen Dagmar och 4G-kommunikation inom smarta elnät

To be able to secure a safe and reliable power supply is becoming increasingly important since society depends on services and functions that need continuous power supply. The delivery rate in Swedish power supply is 99.98 % which insists on a high availability. During the past decade several storms has passed Sweden which resulted in large amount of tree felling leading to extended power outages. During these storms many socially critical activities, such as electric utility company Fortum, experienced disruption in mobile communication which affected the crisis management. This paper has investigated Swedish mobile operators? crisis management at Hi3G, Tele2 and TeliaSonera with a case study of the storm Dagmar that hit Sweden during December in 2011.

Visualisering av produktionseffektivitet : Utveckling av ett verktyg för övervakningav avbrott och presentation av TAK

Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.

Undersökning av deponerat ferrokromstoft : Utvärdering av ny behandlingsmetod

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

?Intoleransen får inte gå därifrån utan att bli ifrågasatt? : En undersökning av so-lärares upplevelser av intolerans på högstadiet och gymnasiet.

This Master's Thesis studies the attitude that library employees have regarding a sex and gender-neutral treatmentof their clients. The analysis is based upon replies to a questionnaire which was submitted though channels directedat library employees, like BIBLIST and BiblFeed. The respondent?s replies contained a number of welldevelopedcomments making the resultant analysis both quantitative and qualitative in nature.In performing the analysis a theoretical framework combining Hirdman?s gender system with symbolic interactionismhas been used together with literature about gender roles.The questionnaire showed that gender neutrality is a complex concept that can be interpreted in many differentways and is therefore easily misunderstood. It is obvious that sex is an important category when respondents aredealing with their clients, but also that sex and gender are problematic concepts which respondents find difficultto know exactly how to relate to.
