Even though protonemal development of bryophytes has been well studied, it remains unknown whether interspecific competition among mosses species affects their early growth and development. This study evaluated the effects of interspecific competition on in vitro germination and gametophyte development between each pair-wise combination from six common moss species: Atrichum undulatum, Bryum argen
Idén om att processuellt generera artificiella världar är gammal. Metoden används både för CGI effekter i filmer och, framförallt, för tevespel. Det görs av stora företag och mindre studios; av professionella programmerare såväl som nybörjare och hobbyister. Det är ett kraftfullt verktyg som möjliggör även små team att skapa enorma världar. Men även om det finns mycket inspiration att hämta kan deThe idea of procedurally generating artificial worlds has been around for a long time. It is used both for CGI effects in movies and, more prominently, for video games. It is done by big companies and small teams; professionals as well as beginners and hobbyists. It is an instrumental tool that enables even the smallest of development teams to create large worlds. While there is a lot of inspirati
PET/CT OCH CANCERBEHANDLING – RESAN MOT ETT BOTEMEDEL OCH HUR DET KAN UPPTÄCKAS Cancer – vi blir alla på något sätt påverkade av denna hemska sjukdom och om vi inte gör något drastiskt kommer det snart vara den främsta dödsorsaken i världen. PET/CT är ett analyssystem som kan bidra till en förbättrad cancerbehandling, men för att verkligen ta vara på all dess information måste det undersökas hur Cancer is a disease affecting practically the entire society in one way or another. A great effort is made to find a cure and positron emission tomography/computed tomography (PET/CT) has recently become a vital part to achieve this goal. The reason for this is because PET/CT provides an opportunity to obtain more tumor information than other techniques, which in turn could improve cancer treatmen
Syfte: Att undersöka ifall det går att generera överavkastning genom att enbart investera i branscherna alkohol, spel, tobak och försvar. Detta genom att jämföra dessa investeringar mot indexet MSCI Europe och den etiska fonden SEB Ethical Europe. Metod: Med hjälp av programmet Thomson Reuters Datastream har fakta kring bolagen tagits fram och sorterats in utifrån branschtillhörighet. Denna data
En styrd grundvattensänkning är ett vanligt inslag i byggprojekt där markarbeten sker under grundvattennivån. Under byggtiden sänks grundvattennivån genom att grundvatten pumpas upp genom installerade brunnar. En sänkning av grundvattennivån minskar portrycket och ökar effektivspänningen i jorden vilket medför marksättningar. Storleken på marksättningar beror på avsänkningens storlek och jordegensDuring a construction project where excavation is made beneath the water table, it is common to perform a lowering of the water table. The groundwater can be extracted by installed wells in the stratum of water-bearing soil. A lowering of the water table results in a decreased pore pressure and in an increased effective stress in the soil. An increased effective stress results in ground settlement
Additive manufacturing (also known as 3D printing and abbreviated AM) opens up for numerous opportunities in increasing business profit while perhaps also improving sustainability. There are some knowledge gaps though in how and when AM could be implemented successfully for production purposes, and as AM is quite information intensive it is also problematic to keep track of advances in technology
Social identity is a well established concept in social psychology, and nationality as social identity has been theorised to function as a powerful tool for political mobilisation in democratic elections. With this in mind, the purpose of this text is to analyse how the Swedish far-right political party the Sweden Democrats constructs the social identity Swede. To this end, a discourse analysis of
Studien undersöker hur musiklärare med diagnosen dyslexi hanterar sin arbetssituation i skolan. Syftet med undersökningen har varit att utforska några av de överväganden och konkreta metoder som används i den praktiska lärargärningen. Studien undersöker även hur dessa musiklärare själva upplever sin situation och hur de förhåller sig till hinder och tillgångar. För att främja bästa möjliga lärsitu
Liten blomma i backen, formad av bondens blod, svett och tårar En bit innan semesterparadiset Smögen, ligger en liten ö med mångårig historia. Här har marken odlats under många hundra år. På sommaren slåttrade man gräset, bar det till höbalar, och korna betade lojt på med utsikt över klipporna och havet. Störningarna var stora på gräsmarkerna, lien skar av växterna och korna betade, för många växWith the gain of productivity in farming the last decades, there has been great loss in species richness. Many plant species that have evolved and adapted alongside to traditional farming and benefiting to the managed land use, are now disappearing in great numbers. Three thirds of Sweden’s endangered plant species are those who thrive in managed grasslands like meadows and grazing areas. The trad
Suicide among young people are a serious problem worlwide as well in Sweden. The main purpose with this study was to examine and understand how suicide can be explained- to identify possible causes to suicide behaviour among young people. Through a qualitative approach, I interviewed six people who are working with young people in different ways. The main- result from this study shows that suicid
Genom införandet av lag (2006:45) om omvandling av fängelse på livstid (OmvL) skapades ett nytt frigivningssystem för livstidsdömda genom en rätt att ansöka om omvandling hos Örebro TR efter att ha avtjänat tio år av det utdömda livstidsstraffet. Omvandlingsprövningen består av fem kriterier, varav ett innebär en bedömning av om det föreligger risk för återfall i allvarlig brottslighet. Om konkretBy the passing of the Act (2006:45) on conversion of imprisonment for life (OmvL), a new system for the release of a prisoner serving life sentence was created, by enabling an entitlement to apply for conversion after having served ten years of the imprisonment. The adjudicate consists of five conversion criteria, one of which involves an assessment of whether there is a risk of a recidivism into
Denna uppsats utreder två förslag på ändringar i den svenska lagstiftningen om offentlig upphandling som presenterats av utredningen "Upphandling och villkor enligt kollektivavtal". Utredningen föreslog, bland annat, att det skall vara möjligt för upphandlande enheter att ställa mer långtgående arbetsrättsliga krav på inhemska leverantörer än de som använder sig av utstationerad personalThis thesis studies two proposed changes in the Swedish public procurement legislation put forth by the government inquiry, "Upphandling och villkor enligt kollektivavtal". The government inquiry suggests, among other things, that it should be possible for contracting entities to require higher labor standards by domestic tenderers, than by tenderers that uses posted workers. This negati
The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a
The objective for this master thesis has been to develop a mathematical model of the actuator parts of the fifth generation Haldex AWD system. The parts to be modeled are the DC-Machine and the pump. Also a model of the elasticity of the clutch has to be derived as well as a model for the hydraulic fluid. These models were then to be implemented in Matlab Simulink. The model was derived by means o
Introduction: Rockwell Automation needs to understand how a lean company wants to visualize different KPIs. Ambu wants to see the value of using such visualization in their company and the effect it might have.Thus the two parts fulfill each other's needs and are the perfect match. Purpose: The purpose of the master thesis is to identify essential KPIs in a medical production process and desi
Saving battery time for mobile devices has been a goal for the industry for many years. With the advent of smartphones, reduction of energy consumption is even more important since they consume a lot more energy than the generation of mobile phones before them. Consumers are demanding longer battery life and greener electronics. One way to meet these demands is to reduce energy consumption. In ord
The human motor control is both robust and stable, despite large delays and highly complex motor systems with an abundance of actuators, sensors and degrees of freedom. The cerebellum is thought help accomplish this by compensating for external loads and internal limitations and disturbances through adaptation, creating inverse models of the motor system dynamics. The cerebellum does also exhibit
The area of power quality has received more and more attention during the last decade. Poor power quality is a growing problem, especially for the industry because it has a negative effect on production efficiency, power consumption and equipment life-span. Active filters are one of the more widespread solutions to these problems. An active filter is often sized and installed to compensate a speci
The overall objective of this study is to describe, analyse and suggest improvements on existing automatic exposure control systems in selected network video cameras. Since an image sensor has a limited dynamic range compared to a real scene, it is necessary to automatically control the exposure level and thus adapt to the amount of light in the scene. This can be done by adjusting parameters such
