Syftet med detta utvecklingsprojekt är att stärka naturvetenskapens roll i grundskolans tidigare åldrar. Att väcka intresse och lust för de naturvetenskapliga ämnena samt för att arbeta praktiskt så att eleverna är delaktiga i undervisningen. Det handlar även om att bekanta sig med naturvetenskapen i vardagen och inse att den är enkel att arbeta med. Materialet består av experiment som eleverna får och lärarhandledningar som följer med varje experiment till lärarna. Materialet är konstruerat till elever och lärare i årskurs 1-3 i grundskolan. Varje experiment har ett mål som ska nås från kursplanerna i naturvetenskap (biologi, fysik och kemi) för år 1-3 och där kan läraren bestämma hur/om eleverna har nått det målet. Lärarhandledningarna är uppbyggda med ”tips innan experimentet”, ”förklaring”, ”resultat”, ”undersök mer” och centralt innehåll”. För att utvärdera materialet fick två lärare i naturvetenskap titta på materialet och säga vad de tyckte om det. Upplevelsen av lärarnas tänkande kring arbetet var väldigt positivt och målet för att arbetet skulle vara lättillgängligt nåddes. En av lärarna skrev ”Du kommer säkert att locka många elever till större och vidare nyfikenhet med ditt material”. Lärarna ville gärna använda materialet och behålla det och det ses som något positivt. Möjlighet till skapande och elevernas intresse tas omhand och detta är förhoppningsvis bara början till att naturvetenskapen lyfts och används mer i skolan. / The purpose of this development is to strengthen scientific role in schools earlier ages. To arouse interest and desire for the natural sciences, as well as to work so that students are involved in teaching. It is also about to become acquainted with natural sciences in everyday life, and realize that it is easy to work with. The material consists of experiments that students and a teacher's guide as follows with each experiment to teachers. The material is designed to students and teachers in grade 1-3 in primary school. Each experiment has a target to be reached from the curriculum in science for years 1-3 and where trainer can determine how/if pupils have reached the goal. A teacher's guide is built with "tips before the experiment", "Explanation", "results", "explore more" and central content". In order to evaluate the material had two teachers in science look at the material and say what they thought about it. Experience of teachers' thinking around the work was very positive and the objective of the work would be accessible was reached. One of the teachers wrote "You will certainly attract many students to larger and further curiosity with your material". Teachers wanted to use the material and keep it and it is seen as something positive. An opportunity for the creation and students' interest will be looked after and this is hopefully just the beginning of that life sciences lifts and is used more in the school.

Eutrophication has long been an environmental problem and the effects from fertilizingarable land is a known source. The degree of phosphorus saturation (DPS)and easily soluble phosphorus (P) are different variables used in different countriesto try to predict the leaching of P from soils. The purpose of this master thesiswas to investigate what variable can be used as a predictor for leached P from soilsand to investigate what extent P leaching from the topsoil can be readsorbed inthe subsoil. The extraction method used for DPS was the Swedish standard lactateextraction and for easily soluble P were distilled water, CaCl2-solution and artificialrainwater with recipe from SMHI used. Three different soils in Sweden were used,two arable soils with different chemical properties and one forest soil. The soilswere filtered (2 mm) and put into columns since the texture was of interest ratherthan the structure. CaCl2-solution was used to saturate the samples and artificialrainwater was used for irrigation. The results showed that easily soluble P is areasonable indicator for leached P and that the subsoil affects the total leachingof P. However, no significant correlation was found between DPS and leached P,indicating that it may not be a suitable indicator of leaching. On the other hand,DPS can be seen as a reasonable indicator for easily soluble P since the correlationtest showed almost significant correlation. The results also showed that the electricconductivity in the leachate correlates to the leached P for the arable soils. For amore reliable result, more soils should be analyzed during more days.

Based on the study of available literature in this thesis are defined easily accessible poisons, which are carbofuran, methanol, ethylene glycol, marijuana, methamphetamine, heroin and cocaine. The thesis is further defined by crime, with those readily available poisons committed on the territory of the Czech Republic. Defined easily accessible poisons were also associated with a particular crime that is committed to them and based on statistical outputs of the Czech Police and the National Drug Headquarters of the Police of the Czech Republic was conducted statistical research that is readily available to these poisons committing a crime on the territory of the Czech Republic, and whether there are differences in crime rates between different regions of the Czech Republic. The second part describes the methodology of work and research questions. The third part consists of the results which graphically compares crime committed with easily accessible poisons. The final part consists of discussions, where they are analyzed the achievements of work. To achieve the objectives in this work used data collection methods, analytical, mathematical and graphical. While writing this thesis I first considered studying literature in easily accessible poisons and study applicable laws, which serve as the legal basis for the definition of crimes. When I was writing a thesis based on research questions: They are easily accessible poisons available in the Czech Republic? There in the CR crime committed using readily available poisons? There are differences between individual regions in the Czech Republic? These research questions were answered by meeting our goals, namely the Czech Republic are readily available poisons available with them commit crime in the crimes committed there are differences between individual regions.

The present work aimed to study the influence of substrate moisture on the productivity of seedlings of a hybrid clone of Eucalyptus grandis x Eucalyptus urophylla under nursery conditions and determine the Kc during the stage of seedling production and establish criteria for the easy management of irrigation in nurseries for the production of eucalyptus. The study was conducted in a greenhouse installed in the area of the Centro de Ciências Agrárias of the Universidade Federal of Espírito Santo, located in the city of Alegre-ES. The experimental design was completely randomized, with five levels of moisture in the substrate 90, 80, 70, 60 and 50% relative to the maximum water holding capacity of the substrate (RCMW) and three replications. The experimental unit was initially composed of 36 plants. The treatments were applied according to the monitoring of the quantity of water contained in the substrate by means of weighing the experimental units and the replenishment of the fraction of water lost by evapotranspiration. To follow the development and growth of seedlings were assessed following morphological parameters: height, collar diameter, leaf area, leaf dry matter, aerial part, root and total. The experimental data obtained were subjected to analysis of variance and when significant, means were compared by Tukey test at a significance level of 5%. The results of this study indicate that water is easily available for seedlings of a hybrid clone of Eucalyptus grandis x Eucalyptus urophylla until the level of 70% of RCMW, the value of Kc is 1.25 and the Irrigation control by weighing method shows be applicable in greenhouses / A escassez de informações referentes ao consumo hídrico de mudas de espécies florestais dificulta o planejamento e o manejo da irrigação em viveiros comerciais que, na maioria das vezes, leva a adoção de critérios subjetivos, acarretando estresse hídrico, principalmente pelo excesso de água, que além de provocar o desperdício de água, causa perdas de mudas por doenças, em virtude do excesso de umidade do ambiente. O presente trabalho teve como objetivo estudar a influência da umidade do substrato na produtividade de mudas de um clone do híbrido Eucalyptus urophylla x Eucalyptus grandis sob condições de viveiro e determinar o Kc durante a etapa de produção de mudas, bem como estabelecer critérios de fácil aplicação para o manejo de irrigação em viveiros destinados a produção de mudas de eucalipto. O estudo foi realizado em casa de vegetação instalada na área experimental do Centro de Ciências Agrárias da Universidade Federal do Espírito Santo, localizada no município de Alegre-ES. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco níveis de umidade do substrato, sendo 90, 80, 70, 60 e 50% em relação à máxima capacidade de retenção de água (MCRA) e três repetições. A unidade experimental foi composta inicialmente por 36 plantas. Os tratamentos foram aplicados em função do monitoramento da quantidade de água contida no substrato por meio de pesagem das unidades experimentais, e na reposição da fração de água perdida por evapotranspiração. Para acompanhar o desenvolvimento e crescimento das mudas foram avaliados os seguintes parâmetros morfológicos: altura, diâmetro do coleto, área foliar, matéria seca da folha, da parte aérea, da raiz e total. Os dados experimentais obtidos foram submetidos à análise de variância, e quando significativa, as médias foram comparadas pelo teste de Tukey ao nível de significância de 5%. Os resultados encontrados neste estudo indicam que a água está facilmente disponível para mudas de um clone do híbrido Eucalyptus urophylla x Eucalyptus grandis até o nível de 70% da MCRA, o valor encontrado de Kc é 1,25 e o método de controle da irrigação por meio de pesagens revela ser aplicável em casas de vegetação

Industrial robots are important for the competitiveness in high wages countries and during the last 10 years the number of installed robots have tripled in the world. A combination of the high demand for robots and system integration and a lack of competence makes it hard for companies to acquire the robot applications they require as well as maintain and improve them. By using easily programmable robots developing the required competence for system integration is uncomplicated, however, the tradition of buying turn-key automation has led to a lack of competence in in-house system integration. Collaborative robots are often regarded as more easily programmable than traditional robots. By performing a case study with a collaborative robot, the thesis aims to map and present the process and competencies needed to perform system integration in-house. The thesis identifies a process for system integration including education, initialization, application, design, installation and preparation, programming, evaluation, production and presents them in a final model. Further, the thesis presents project supervision, project leadership, project participation, organizational change leadership, problem-solving, process and system, programming, installation, technology, method and safety and regulation competencies as necessary for successful system integration inhouse. Finally, the steps of the process and the competencies are overlaid as to show which competencies are necessary for which process steps. The thesis provides a guide for in-house system integration not previously found in academia.

The increasing complexity of systems and the demand for increasing implemented functionalit-ies within the systems necessitate a paradigm shift in development approaches. While traditionalsystems engineering relies heavily on textual documentation, the future calls for a more stream-lined, digital method such as Model-Based Systems Engineering (MBSE). MBSE utilises models tostore data, mitigating textual ambiguity and providing stakeholders with a unified source of inform-ation. Despite its potential, the adoption of MBSE presents challenges because of the need of newpractitioner skill-sets. The thesis investigates the feasibility of implementing an easily adoptable MBSE, using a limitedset of SysML elements and diagrams, approach within the space industry. Through the developmentof guidelines, steps, and goals, a model of an industry-related system is constructed. The createdmodel serves as a demonstration to industry engineers, evaluating the suitability of the proposedguidelines. The thesis concludes the need for maturity of MBSE, its tools, and the need for harmonisationwithin the space industry to establish acceptance among the practitioners. These are the crucialpoints where development and refinements are needed to gain the trust and interest of the end usersof the modelling activities and adopting the proposed methods.i
