Lack of straightness in timber is the most frequent complaint regarding solid (and laminated) timber products worldwide. Nowadays, customers demand higher quality in the shape stability of wood products than they did earlier. The final distortion of timber boards is mostly caused by moisture-related stresses in wood (drying distortions) and growth-related stresses (distortions appearing when logs
Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande. En möjlig väg mot enklare efterbehandlingssystem är anvädningen av Homogen Kompressions Antändning (Eng: HCCI) motor cykeln. Den huvudsaklThe current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o
Popular Abstract in Swedish I studier rörande de yngsta barnen saknas ofta genusperspektiv. Ett syfte med studien var därför att undersöka interaktionen mellan barnen (1-3 år gamla) och förskolepersonalen på småbarnsavdelningarna vid tre förskolor i ett genus- och kontextuellt perspektiv. Ett annat syfte var att undersöka pedagogernas föreställningar om barn och genus. Ett tredje syfte var att disIn studies concerning the youngest children, the toddlers, the gender perspective is often missing. One aim of the study was, therefore, to investigate the interaction between children and preschool teachers in day care centres in a gender and a contextual perspective. Another aim was to investigate the inner representations of the preschool teachers concerning children and gender. A third aim was
One of the most dynamic interactions between humans and technology of our time is the development of artificial intelligence, materialized in various types of communicative robots. Thrilling questions are raised about how human-like these robots can be and how far this interaction will go. It is no exaggeration to state that speculations about the robots’ role in our lives far exceed what we know
Background: Intraguild predation (IGP) is widespread but it is often neglected that guilds commonly include many layers of dominance within. This could obscure the effects of IGP making unclear whether the intermediate or the bottom mesopredator will bear higher costs from the emergence of a new top predator. Methodology/Principal Findings: In one of the most extensive datasets of avian IGP, we an
Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Results from a research field monitoring program by daily resistivity measurements in Sweden clearly show long term changes in resistivity in the embankment dam. The results indicate that resistivity monitoring ca

The terminal goal of the thesis is to come down to which types of mounts to develop for the active lifestyle user and thereafter, create a couple of 3D-printed mounts for these placements. Moreover, suggestions for optimizing the Clip itself and its user
With increasing competition and noise level in the third sector, Germany’s non-profit organisations have to start considering alternative ways of how to be heard by their target audiences and how to raise funds for their projects. Additionally, with technological developments and the rise of Web 2.0 this becomes particularly challenging. Strategic planning of communication and public relations act
Tvångsvård av barn är ett mycket allvarligt ingrepp i den personliga integriteten. För att barn ska kunna tillförsäkras god vård – utan samtycke – måste det därför ställas höga krav på rättssäkerhet. Uppsatsen syftar till att undersöka huruvida rekvisitet något annat socialt nedbrytande beteende i 3 § lag (1990:52) med särskilda bestämmelser om vård av unga (LVU) uppfyller kravet på rättssäkerhet.Compulsory care of a child is a very serious invasion of their privacy. In order to ensure good care of a child – without consent – high requirements must be placed on the legal certainty. This essay intends to examine if the necessary prerequisite any other socially destructive behavior in § 3 the Care of Young Persons Act (CYPA), meets the requirements for legal certainty. Special attention is p
Hearing is our second most important sense. The main focus of a surveillance camera is obviously the video but the audio shouldn't be neglected. It is possible to hear what the camera can't see and what is said in a conversation can't be showed in a video. Therefore there are good reasons to always try and achieve the best audio possible. This is not an easy task since cameras are oper
Vad tänker du på när du hör ordet solprognos? För vissa är det viktigt i planeringen av semestern, andra kanske för att skydda sig mot farlig UV-strålning. Vad många inte vet är att solprognoser är en viktig komponent i vårt energisamhälle där förnyelsebara energikällor som solkraft och vindkraft ökar kraftigt runt om i världen. Att göra träffsäkra prognoser för inkommande solstrålning har dock viSolar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for
Denna uppsats syftar till att utreda Dublinförordningens reglering av ensamkommande barn. Genom att använda en rättsdogmatisk metod analyseras vad det innebär att den av EU:s medlemsstater som blir ansvarig för att pröva ett ensamkommande barns asylansökan ska fastställas som ansvarig under förutsättning att det är för barnets bästa. Även en EU-rättslig metod används då det mest centrala materialeThe purpose of this thesis is to examine the Dublin Regulation and unaccompanied minors. By using a legal dogmatic method the thesis analyses the meaning of the child´s best interest when determining which of the EU member states that is responsible for examining an unaccompanied minor´s asylum application. Legal material from the EU has been of significant importance for this thesis, and therefor
In this thesis, the Arctic sea ice volume and thickness evolution over the time period 1850-2100 is analysed. The analysed data is provided by the CMIP5 climate models, which contributed their output for the IPCC Fifth Assessment. The results were compared to the reanalysis data series PIOMAS. Three RCP projections, with different greenhouse gas emission scenarios, were used for the time period 20
In Sweden 16 national goals have been elaborated to aim for an environmentally sustainable society. These goals should not only be implemented at a national level but also at the regional and community level. In Lund 13 documents have been developed, for 13 of the 16 national goals describing the environmental state in Lund associated to the goal in question. These documents will lead to local env
Uppsatsen redogör för rättsreglerna kring omplacering och turordning vid arbetsbristuppsägningar. Det finns ett omfattande regelverk kring anställningsskyddet i Sverige. Det reglerar hur arbetsgivare ska uppträda då uppsägningar ska äga rum. Det krävs saklig grund för att en arbetsgivare ska ha rätt att säga upp en arbetstagare. Detta framgår tydligt ur 7§ anställningsskyddslagen. För att sakligThis essay describes the legal rules regarding relocation and order of priority in connection with termination of employment due to redundancy. There are comprehensive regulations on employment protection in Sweden. It regulates how employers should act when the redundancies will take place. It requires grounds for dismissal for an employer to have the right to terminate an employee. This is evid
Regionalism, that has been always with us in different forms throughout the history and emerged as an alternative theory after the end of Cold War, enables us to explain new world order. Since the end of WWII, there are two types of regionalism explaining the dynamics of regional formations. The one that came into question from the end of WWII till end of Cold War is names as ‘old’ regionalism and
Detta projekt syftar till att förstå vilka synliga effekter klumpar av mörk materia i Vintergatan kan ha på sönderslitna stjärnsystem, och om klumparna av mörk materia är tillräckligt många för att orsaka observerbara effekter. Vår nuvarande model av hur Universum utvecklades efter The Big Bang kallas för Lambda Cold Dark Matter-kosmologi, förkortat LambdaCDM. Lambda står för mörk energi, och deleThe current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way. The stream-subhalo i
