Ljusets betydelse för rotknoppars groningsvillighet i åkermolke (Sonchus arvensis L.)

This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.

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..

Individen kommer inte långt själv för ensam är man ingenting : En studie om arbetsmiljöns påverkan på hälsan

The purpose of this thesis is to achieve a greater understanding of how the social workers at the family unit in one of Stockholm municipalities comprehend the work environment at the workplace. Our aim is also to find out how the work environment can affect the health of the social workers in the form of their wellbeing and comfort at the workplace. In order to answer our purpose we conducted interviews of all social workers at the family unit in one of Stockholm municipalities that describe how they experience the work-environment in the workplace and how it influences their health.  We have analyzed the interview material in a thematic analysis based on three theoretical perspectives; SOC, claim ? control - support and Human relations. We have also coupled the interview material to the background chapter in this thesis that describes how a good working environment should be structured.  The chosen method characterizes an abductive process.

Information management inom humanitära frivilligorganisationer. En kartläggning och utvärdering av informationsbevarande inom svenska Röda Korsets huvudkontor

The Swedish working-class author Ivar Lo-Johansson (1901-1990) wrote a collection of one hundred short stories between the years 1968-1972. His other productions, generally speaking, have partially different social reform purposes, but, according to himself, these short stories were written with the intention to be totally free of tendencies (even though he himself doubted that he succeeded with this).During the same period that these short stories were published, the Swedish social democrats were under the challenge of radical movements that, mainly on the radical left?s ideological foundation, had a relatively strong influence in Sweden, among other countries, from the mid 1960?s to the late 1970?s. Since Lo-Johansson mainly seemed to have supported the politics of the social democrats, the purpose of the investigation in this thesis has been to see if he ? in the three short stories: Vikingakärlek (1970), Rikslögnaren (1971) and Ansgars resa till Sverige (1972) ? is conveying an ideological use of history and basic political values that were used by the social democratic party during this time period.

Födoämnesallergi : Föräldar och barns upplevelse av förskolans bemötande

In this essay I have investigated how two families, with children, who have food allergies, experience what support and what treatment they get in preschool for their difficulties. I have interviewed two children and two parents. The study shows that the interviewed parents believe that more knowledge in the community and among staff in preschool, about food allergies, is needed. Parents wish that the staff should write an action plan that describes how to deal with children who have food allergies and that preschool invites parents and children to record results. It is important to consider an inclusive attitude so that children don?t feels excluded.There is some research going on around this subject and researchers agree that the incidence of food allergies in the society is growing, but that it is difficult to be able to present a certain theory why, and what the underlying factors are.

Finns det faktorer som särskiljer Stockholmsbörsens sanktionerade bolag från dess övriga bolag - En studie om Nasdaq OMX Stockholms Disciplinnämnd

Abstract: The purpose of this study is to examine whether companies listed at Nasdaq OMX Stockholm (Stockholmsbörsen) sanctioned by the legal unit Nasdaq OMX Disciplinary Committee (Disciplinnämnden), could be distinguished from the remaining companies that have not been sanctioned. As Stockholmsbörsen is the most influential unit when trading shares in Sweden, listed companies need to behave in legal aspects. Actions and decisions that affect investors do also influence the listed companies and their performance. Some companies might be tempted to manipulate financial statements and public information to retain stakeholders; other miss to report properly without being fraudulent. To control this, the legal unit Disciplinnämden is introduced.

Konceptstudie av drivmodul till bandskotare med hybriddrift

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Procedurellt minne hos universitetsstuderande med dyslexi

Dyslexi är en form av läs- och skrivsvårighet som inte kan förklaras av t.ex. bristfällig undervisning, låg begåvning eller synproblem. Orsaken till dyslexi anses vanligen vara nedsatt förmåga av fonologiskt processande. Flera studier har dock visat att dyslexi även är förknippat med språkliga, kognitiva och motoriska svårigheter som inte kan förklaras av nedsatt förmåga av fonologiskt processande. Det procedurella minnessystemet engageras vid inlärning, processande och konsolidering av kognitiva och motoriska färdigheter.

Omvårdnad av hästar med mugg för att undvika omotiverad antibiotikaanvändning

Pastern dermatitis is a common condition among horses. It is a symptom, a reaction in the skin of the pastern rather than a diagnose. There are a lot of homemade treatments when you ask horse owners how they handle pastern dermatitis, but what does the science say about how it should be treated? Today there is a growing problem with antibiotic resistance, but how good are the veterinarians on testing for resistance before they describe antibiotics? Bacteria and fungus is seldom the primary cause for pastern dermatitis, the reaction is often secondary to environmental factors. It?s difficult to diagnose the primary factor and it´s even more difficult when the horse has been treated in different ways before the veterinarian gets involved.

HemoCue Cognatus - Ett Intelligent Analysinstrument

HemoCue AB is a multinational corporation targeted on manufacturing point-of-care analysisinstruments for medical treatment. Their main product, the DM 201, is outdated and has bigissues gaining new market shares. For example, no medical treatment center in Sweden usesDM 201 frequently. The project of developing a new instrument to replace it was assignedtwo students at the development engineering program at Halmstad University. The projectalso included integration of the new platform for DM 202 to HemoCue AB:s remainingproducts.The project began by defining the different technical areas concerned.

Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
