This thesis deals with the optimization of the production technology of the cap tube made by injection molding. Series production is set at 5 000 000 units per year; the minimum time of the production is 5 years. A literary study is developed, focusing on the technology of injection molding in molds including the possibilities of the optimization of the production by changing the structure of the mold. The practical part of the thesis is devoted to the optimization of existing mold with cold runner system for the production of the cap tube, using the hot runner system supplied by Synventive. The change of the structure of the mold involves changing the three plate mold to a two plate mold. It is about changing the fixed part of the mold in which the hot runner system is placed; it is composed of standards parts of the company HASCO. Based on the technological parameters the injection machine Krauss Maffei KM 80-380 CX is chosen. There is a technical-economical evaluation of the optimization of the production by using the hot runner system at the end of the thesis.

Syftet med detta examensarbete var att undersöka vad det finns för didaktiska möjligheter i att utföra ekokritiska läsningar av dystopisk skönlitteratur vid undervisning om hållbar utveckling i svenskämnet. För att undersöka detta utfördes en ekokritisk läsning av science fiction- romanen Blade Runner, originaltitel Do Androids Dream of Electric Sheep, av Philip K Dick. Tanken enligt mig var att romanen och dess skildring av en dystopisk värld kunde vara intressant att uppmärksamma i gymnasiet samt använda som underlag för diskussioner om potentiella framtidsscenarion. Utöver det ville jag, genom min analys, visa på vilka frågor gällande hållbar utveckling som en ekokritisk läsning av romanen kan lyfta fram. Utifrån detta ville jag sedan diskutera vilken potential just denna roman och den dystopiska genren i allmänhet kan ha i svenskundervisningen. Resultatet visade att det, i en ekokritisk läsning av romanen, finns tolkningsmöjligheter som belyser alla de tre huvudområden som Skolverket beskriver finns inom hållbar utveckling. Det betyder med andra ord att det finns möjligheter att öppna upp för diskussioner om hållbar utveckling utifrån ekokritiska läsningar av romanen. / The purpose of this degree project was to investigate what didactic possibilities can be found by performing ecocritical readings of dystopic literature while teaching students about sustainable development in the subject of Swedish. To investigate this, an ecocritical reading of the science fiction-novel Blade Runner, original title Do Androids Dream of Electric Sheep, by Philip K Dick was performed. My thought was that the novel and its depiction of a dystopic world could be interesting to acknowledge in an upper-secondary school environment, and use as a foundation for discussions about potential scenarios of the future. In addition to this I wanted to, through my analysis, show which questions regarding sustainable development that an ecocritical reading of the novel could generate. Furthermore, I wanted to discuss what potential this certain novel and the dystopic genre in general could have for teaching in the subject of Swedish.  The results showed that there are, in an ecocritical reading of the novel, room for interpretations that highlights all of the three main areas that Skolverket describes as integral parts of sustainable development. In other words, the evidence suggests that there are possibilities to open up for discussions regarding sustainable development from ecocritical readings of the novel.

Thesis (M.Sc.(Plant Protection)) -- University of Limpopo, 2022 / Runner beans are extremely sensitive to root-knot (Meloidogyne species) nematodes. Phytonematicides had been consistently used in managing population densities of Meloidogyne species in various crops, with the application technologies being restricted to the ground leaching technology (GLT) and botinemagation technology, each with its own advantages and disadvantages. The use of seeds as carriers of active ingredients of phytonematicides and then drying prior to sowing, is being considered as another potential application strategy in seeds with hypogeal germination. In such seeds, during seedling emergence the seed cover and the endosperm remain below the soil surface, just above the developing root system. As a result, in phytonematicide-primed seeds, the seed structures could serve as carriers for the active ingredients of phytonematicides. In cucurbitacin phytonematicides, Nemarioc-AL and Nemafric-BL phytonematicides contain cucurbitacin A and B, respectively as active ingredients. The objectives of the study were two-fold, namely, to determine whether runner bean (Phaseolus coccineus L.) seeds would (1) serve as carriers of active ingredients of cucurbitacin-containing phytonematicides without affecting seed germination under in vitro conditions, (2) serve as carriers of cucurbitacins intended for suppression of M. incognita population densities under greenhouse and microplot conditions. Two separate studies were conducted under laboratory conditions, with seven treatment solutions at 0, 2, 4, 8, 16, 32 and 64% Nemafric-BL or Nemarioc-AL phytonematicide. After exposure to separate solutions for 2 h, runner bean seeds were dried on laboratory benches for 72 h. Treatments were arranged in a completely randomised design (CRD), with 8 replications. Two layers of filter papers were placed inside each Petri dish seeded with 10 primed and dried seeds. Petri dishes were incubated inside LABCON growth chamber at 25ºC and 75% relative humidity. Successful seed germination, viewed as emergence of radicle from the testa, was recorded daily for a period of 10 days, with each count being removed from Petri dish to avoid re-counting. Under greenhouse and microplot conditions, primed-and dried seeds were sown in plastic pots containing 2 700 ml steam-pasteurised sandy loam soil, arranged in a randomised complete block design, replicated six times and eight times, respectively. Each seedling was inoculated by distributing 5 000 eggs and second-stage juveniles (J2) of M. incognita race 4 using a 50 ml plastic syringe. Originally, pots were irrigated using 500 ml chlorine-free tapwater, which was reduced to half after seedling emergence at every other day. Plant variables were collected at 56 days after inoculation and data were subjected to the Curve-fitting Allelochemical Response Dose algorithm model. In vitro, germination percentage (R 2 = 0.96), radicle length (R 2 = 0.89) and plumule diameter (R 2 = 0.96) versus Nemarioc-AL phytonematicide exhibited positive quadratic relations. Similarly, the variables versus Nemafric-BL phytonematicide, exhibited positive quadratic relations. In vitro, Mean Concentration Stimulation Point (MCSP) value of Nemarioc-AL phytonematicide on runner bean seeds was 1.05%, whereas for Nemafric-BL phytonematicide MCSP value was 0.58%. Under greenhouse conditions, plant height (R 2 = 0.97), chlorophyll content (R 2 = 0.92), dry shoot mass (R 2 = 0.98), dead nodule number (R 2 = 0.90), total pod number (R 2 = 0.97) and active nodule number (R 2 = 0.93) versus Nemarioc-AL phytonematicide exhibited positive quadratic relations., Similarly, chlorophyll content (R 2 = 0.95), gall rating (R 2 = 0.82), dry shoot weight (R 2 = 0.69), stem diameter (R 2 = 0.85) and total nodule number (R 2 = 0.86) versus Nemafric-BL phytonematicide exhibited positive quadratic relations. Under greenhouse conditions, MCSP values for Nemarioc-AL and Nemafric-BL phytonematicides were 4.18 and 3.69%, respectively. Under microplot conditions, total number of nodules (R 2 = 0.88), number of nodules dead (R 2 = 0.99), number of nodules active (R 2 = 0.95), fresh root mass (R 2 = 0.99), and fresh pod mass (R 2 = 0.99) versus Nemarioc-AL phytonematicide, exhibited positive quadratic relations, whereas plant height (R 2 = 0.85), number of nodules dead (R 2 = 0.87), dry shoot mass (R 2 = 0.97), fresh root mass (R 2 = 0.97) and total number of nodules (R 2 = 0.63) versus Nemafric-BL phytonematicide exhibited positive quadratic relations. Under microplot conditions, MCSP values for Nemarioc-AL and Nemafric-BL phytonematicides were 3.76 and 3.93%, respectively, each with ∑k = 0. All degrees of Nemarioc-AL and Nemafric-BL phytonematicides profoundly reduced nematode numbers under greenhouse and microplot trials. Based on the information obtained from this study, it was confirmed that runner bean (P. coccineus) is sensitive to Nemafric-BL and Nemarioc-AL phytonematicides supported by the Curve-fitting Allelochemical Response Dose (CARD) model results due to most plant variables that had sensitivity values of zero. In conclusion, the priming technology should be developed further since it has the potential of being successful in nematode management in seeds with hypogeal germination / National Research Foundation (NRF) and Potatoes South Africa

Data processing is generally defined as the collection and transformation of data to extract meaningful information. Data processing involves a multitude of processes such as validation, sorting summarization, aggregation to name a few. Many analytics engines exit today for largescale data processing, namely Apache Spark, Apache Flink and Apache Beam. Each one of these engines have their own advantages and drawbacks. In this thesis report, we used all three of these engines to process data from the Carbon Monoxide Daily Summary Dataset to determine the emission levels per area and unit of time. Then, we compared the performance of these 3 engines using different metrics. The results showed that Apache Beam, while offered greater convenience when writing programs, was slower than Apache Flink and Apache Spark. Spark Runner in Beam was the fastest runner and Apache Spark was the fastest data processing framework overall. / Databehandling definieras generellt som insamling och omvandling av data för att extrahera meningsfull information. Databehandling involverar en mängd processer som validering, sorteringssammanfattning, aggregering för att nämna några. Många analysmotorer lämnar idag för storskalig databehandling, nämligen Apache Spark, Apache Flink och Apache Beam. Var och en av dessa motorer har sina egna fördelar och nackdelar. I den här avhandlingsrapporten använde vi alla dessa tre motorer för att bearbeta data från kolmonoxidens dagliga sammanfattningsdataset för att bestämma utsläppsnivåerna per område och tidsenhet. Sedan jämförde vi prestandan hos dessa 3 motorer med olika mått. Resultaten visade att Apache Beam, även om det erbjuds större bekvämlighet när man skriver program, var långsammare än Apache Flink och Apache Spark. Spark Runner in Beam var den snabbaste löparen och Apache Spark var den snabbaste databehandlingsramen totalt.

Sediment erosion is a major challenge for run-of-river power plants, especially during flood periods. Due to the high content of hard minerals such as quartz and feldspar carried in the river, substantial damage is observed on the turbine components. Material is gradually removed, thus the efficiency of the turbine decreases and the operating time of the turbine reduces. Hydro power plants situated in areas with high sediment concentration suffer under hard conditions, where turbine components could be worn out after only a short period of three months. This short life expectation causes trouble for energy production since the replacement of new turbine parts is a time consuming and costly procedure. It is desirable to design a Francis runner which will withstand sediment erosion better than the traditional designs. The literature states that an expression for erosion is velocity to the power of three. By reducing the relative velocities in the runner by 10%, the erosion will decrease almost 30%. The objective is to improve the design of a Francis turbine which operates in rivers with high sediment concentration, by looking at the design parameters in order to reduce erosion wear. A Francis turbine design tool was developed to accomplish the parameter study. In the search for an optimized Francis runner, several design proposals were compared against a reference design by evaluating the turbine’s performance. The hydraulic flow conditions and the prediction of erosion on the turbine components are simulated by analyzing the models with a Computational Fluid Dynamic (CFD) tool. A Fluid Structure Interaction (FSI) analysis ensures that the structural integrity of the design is within a desired value. Results from this research show that it is feasible to design a runner with an extended lifetime, without affecting the main dimensions and hydraulic efficiency.

Resumo: Para obtenção de bons resultados de produtividade com menor custo, o uso do espaçamento entrelinhas e densidades de plantas na linha devem ser adequados, pois, a população de plantas é um dos fatores que se destacam por afetar diretamente os componentes de produção. Tendo em vista a escassez de informações relacionadas ao comportamento de variedades de amendoim, principalmente as rasteiras, cultivadas em diferentes populações, propôs-se no presente trabalho estudar os efeitos da densidade de plantas no desenvolvimento e produtividade do amendoim. Foram conduzidos três experimentos envolvendo três cultivares, sendo duas rasteiras Runner IAC 886 e IAC Caiapó e uma ereta IAC Tatu ST. Foram estudadas quatro densidades de plantas (22, 18, 12 e 6 plantas/m) mantendo-se o espaçamento entrelinhas em 0,90 m. Utilizou-se o delineamento em blocos ao acaso com quatro repetições, sendo a parcela experimental constituída de 7 linhas de 5 m de comprimento. Os resultados foram submetidos à análise de variância pelo teste F e as médias foram comparadas pelo teste de Tukey a 5% de probabilidade. As características relacionadas ao crescimento vegetativo foram pouco influenciadas pelas densidades de plantas. A cultivar Runner IAC 886 apresentou maior número de ramificações na menor densidade de plantas e a IAC Caiapó, apresentou maior comprimento de ramificações na maior densidade de plantas. Dentre as características relacionadas à produtividade, a mais afetada pela densidade de plantas foi o número de vagens por planta. A cultivar IAC Caiapó apresentou maior número de vagens por planta na menor densidade testada. As cultivares rasteiras Runner IAC 886 e IAC Caiapó apresentaram produtividades semelhantes nas diferentes densidades testadas e a ereta IAC Tatu ST, maiores produtividades nas maiores densidades de plantas. / Abstract: The row spacing and plants density must be adequate for obtaining yield increases with lower costs, since the plants population is one of the main factors directly affecting the yield components. Once the information related to peanut varieties behavior in different populations is scarce, the aim of the present work was to study the effect of plants density on peanut yield and development. Experiments were carried out using three cultivars, the runner type ones Runner IAC 886 and IAC Caiapó and the bunch type IAC Tatu ST. Four plants density (22, 18, 12 and 6 plants per meter of row) were evaluated in 0.90 m row spacing. The randomized block design was used with four replicates, being the experimental plots composed by 7 rows of 5 m length each. Data were submitted to the variance analysis by the F test and means were compared by the Tukey test (5% probability). Traits related to vegetative growth were lightly affected by the different plants density. The higher plant branching was observed at the lower density for the Runner IAC 886 cultivar, while the IAC Caiapó showed higher plant branching at the higher density. Among the yield components, the number of pods per plant was the most affected trait by the plants density change. The IAC Caiapó cultivar showed the higher number of pods per plant at the lower tested density. Otherwise, the runner type cultivars Runner IAC 886 and IAC Caiapó showed similar results for yield at the different tested densities, whereas the bunch type IAC Tatu ST had higher yield at higher plants density. / Orientadora: Maria Aparecida Pessôa da Cruz Centurion / Coorientadora: Fabíola Vitti Moro / Banca: João Carlos de Oliveira / Banca: Ivana Marino Bárbaro / Mestre

Runner IAC 886). O experimento foi instalado no município de Jaboticabal, SP, em um Latossolo Vermelho de textura média. Os tratamentos constaram de dois espaçamentos entrelinhas de semeadura (80 e 90 cm), divididos em dois grupos. No primeiro as plantas daninhas foram controladas desde a emergência até os 0 (inteiramente no mato), 30, 45, 60, 82, 97 e 112 dias. Após estes períodos, as plantas daninhas que germinaram foram deixadas crescer livremente. No segundo, as plantas daninhas conviveram com a cultura pelos mesmos períodos do grupo anterior, sendo que após cada período foram removidas das parcelas. O delineamento experimental foi o de parcelas subdivididas, nas quais se constituíram por parcelas os diferentes espaçamentos e por subparcelas os períodos, totalizando 28 tratamentos em quatro repetições. As principais plantas daninhas presentes na área foram Digitaria sp., Xanthium strumarium, Acanthospermum hispidum e Cenchrus echinatus. Para uma perda tolerável de 5% de produtividade, o período crítico de prevenção da interferência foi dos 27 aos 76 e dos 35 aos 96 dias após a emergência para os espaçamentos de 80 e 90 cm, respectivamente, sendo que a queda de produtividade das parcelas mantidas no mato em relação às no limpo foi de mais de 80%, independentemente do espaçamento. / The research was conducted to evaluate the effect of reduced row spacing on the extension of interfeence periods on peanut yield (Arachis hypogaea cv. IAC Runner 886). The experiment was conducterd in Jaboticabal, SP, Brazil, on a Red- Latosol of medium texture. The treatments consisted of two row spacing (80 and 90 cm), divided in two groups. At the first one, the weeds were controlled since the emergence until 0 (kept with the weeds), 30, 45, 60, 82, 97 and 112 days after the peanut emergence. After those periods, the weed emerged and grew without control. At the second group, the weed grew since the peanut emergence during the same periods from the first group, however, at each period the weeds were removed from the plots. The experimental design was the split-plot scheme, being the main plots constituted by different row spacing and subplots constituted by periods of weedy or weed control, in a whole of 28 treatments with four replicates. The main weed at the area where: Digitaria sp., Xanthium strumarium, Acanthospermum hispidum and Cenchrus echinatus. To an acceptable yield loss of 5%, the critical period of interference control was from 27 to 76 and from 35 to 96 days after the emergence at the spacing rows of 80 and 90 cm, respectively, but the yield reduction at the non-controlled weed plots related to the plots free from interference was more than 90%, independent of the row spacing.
