Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

Alternativ till fortsatt elektrisk generering i Olidan

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Vidareutveckling av provplattform för mätning av kosmisk strålnings inverkan på DRAM

Sammanfattning: SAAB Communication i Linköping sysslar med konsultverksamhet mot ett flertal nationella och internationella företag inom både den civila och militära sektorn. Fokus ligger på flyget med uppdrag inom telesystem, radiosystem, signaturanpassning, EMC, atmosfärisk påverkan mm. I det sistnämnda ingår även kosmisk strålnings inverkan på elektronik. Den fortsatta miniatyriseringen av elektronik, speciellt minneselektronik leder till ökad känslighet mot den kosmiska partikelstrålningen som ständigt regnar ner på jorden, därför är det extra noga att minnen testas innan de sätts i bruk vid flygburna system. Syftet med detta examensarbete är att konstruera en provplattform som registrerar fel som uppkommer i ett DDR2 SDRAM minne vid påverkan av den ovannämnda strålningen.

Värderar venture capitalbolag koncerngoodwill och har värderingen påverkats av införandet av IFRS 3: en fallstudie av fyra venture capitalbolag

Goodwill är ett omtvistat ämne inom redovisning. I dagens samhälle har företag haft friheten att kunna välja vilken regel i anknytning till goodwill de vill använda och det med hänsyn till vilket resultat de eftersträvar. Våren 2004 offentliggjorde International Accounting Standard Board en ny standard, IFRS 3 för redovisning av företagsförvärv. IFRS 3 går ut på att goodwill inte längre är föremål för planenliga avskrivningar utan istället ska företag genomföra ett ?impairment test? som innebär att företagen genomför en ingående analys av goodwillvärdet årsvis.

Sambandet mellan kondition och självskattad hälsa

ABSTRACT Background: Health and ill-health are multifaceted concepts. Previous research has shown that physical activity and the level of cardio respiratory are important parts of leading a healthy lifestyle. Possibly, it?s so important that the Occupational Health Service should focus even more on this.Aim: The aim was to investigate if there was a relationship between the level of cardio respiratory fitness and self-rated health, and between the level of cardio respiratory fitness and physical and mental ill-health.Method: The study was conducted using a quantitative method in the form of a cross sectional study. Data was collected from an Occupational Health Service, containing answers to a questionnaire on work environment and health and test values ??from completed cycle fitness tests.

Det subjektiva välbefinnandet på arbetsplatsen : Effort-reward imbalance modellen inom handels

Följande studie avser att undersöka relationen mellan engagemang, belöning och välbefinnande på arbetsplatsen. Siegrist (1996) förklarar sambandet genom Effort-Reward Imbalance model (ERI), något som denna studie kombinerar med Dieners (1986) teori om subjektivt välbefinnande. 156 personer deltog i enkätstudien, där 97 var kvinnor. Enkäterna var utformade med påståenden där deltagarna fick skatta sina svar. Datan analyserades genom en multipel regressionsanalys, korrelationer och t-test.

Att beskriva och jämföra en expertgrupp och intensivvårdssjuksköterskors överensstämmelse i att detektera delirium hos intuberade, respiratorbehandlade patienter med sedering/analgesi, före och efter en utbildningsintervention : En kvasiexperimentell stud

The aim: was to describe and compare a group of experts and critical care nurses' agreement in detecting delirium in intubated, ventilator treated patients with sedation / analgesia, before and after an in house training intervention with the instrument Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).Method: A quasi-experimental study, one group pretest - posttest design. A convenience sample of 17 critical care nurses in a general intensive care unit included. To detect delirium the instrument CAM-ICU was used, 21 paired tests before and 22 after an educational intervention.Main Results: The results showed that after an in house training intervention sensitivity and kappa coefficient improved of the characteristic 1 "acute onset and fluctuating course," an improvement that was significant. In other features, and overall values were signs of numerical improvement and deterioration in sensitivity, specificity and kappa coefficient but no significant change.Conclusion: Implementing a new instrument for detecting delirium in clinical practice requires education and follow-up. A small sample of critical care nurses with varying ability to use the new instrument and the fact that patients' status may change rapidly making it difficult to draw any conclusions from this study.

Ytbearbetning av ersättningssten för kulturhistoriska byggnader

The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

En jämförelse mellan TLS och UAV-fotogrammetri : Inmätning av hårdgjorda ytor

At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

Under extrem press En kvantitativ studie av hur svensk dagspress förhåller sig till politisk extremism

Authors: Martin Mederyd Hårdh, Frida Nygren, Daniel PaulssonTitle: Under Extreme PressureLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishMethod: Quantitative content analysisPages: 38Politically motivated extremism is a common topic in the Swedish public debate ? and hence in Swedish media. The purpose of our study is to get an idea of how the media relates to the extremist groupings. On a traditional political scale, ranging from left to right, our study focuses on the Swedish extremists who figure on the outskirts of this scale; The ones who denounce the current system and opt for violence to change it.Violence is often an instrument used to get extreme political ideals in the public eye, and is seen as a threat to the Swedish democracy and the public in general. Both sides argue that the Swedish press is tendentious and treat the various extremist groups differently, airing their distrust for the media as a propaganda tool for these groups to establish themselves in the public debate.Our study consists of a quantitative content analysis where we study articles published in print by seven major Swedish newspapers.

Visuomotorisk utveckling mätt med Bendertestet : En jämförelse mellan för tidigt födda och fullgångna barn vid 5 1/2 års ålder.

SammanfattningBarns utveckling under de sista förskoleåren är nyckeln till en bra skolstart. Visuomotorik är en av de faktorer som krävs för att tillägna sig skolans basfärdigheter. För tidigt födda barn är en grupp som enligt tidigare forskning löper risk för en sämre visuomotorisk utveckling. I den här studien mättes visuomotorik med Bender Gestalt Test med utvärderingssytem utvecklade av främst Elizabeth Koppitz (1963, 1975). I studien jämfördes för tidigt födda barns (n=175) och matchade fullgångna barns (n=125) Bender-resultat vid 5½ års ålder.

Hur viktig är statens styrka för ekonomiskt välstånd?- En studie av alla världens länder

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Comparison between different freezing and thawing methods for human spermatozoa

Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.
