La variabilidad espacial en los atributos geometalúrgicos de los depósitos es un parámetro crucial desde la etapa de exploración, lo cual condiciona e influye en el procesamiento mineral. En consecuencia, el objetivo de esta investigación es elaborar la simulación geometalúrgica del Índice de Trabajo de Bond para un depósito pórfido cuprífero. Para esto se utilizó información de atributos primarios y de respuesta correspondientes a zonas minerales, litologías y de BWi contenidos en 1,449 muestras de sondajes exploratorios. Se realizó el análisis exploratorio de datos de dicha información y se definieron unidades geometalúrgicas fundamentándose en el conocimiento geológico y de procesamiento que valida el comportamiento de cada una de ellas dentro del depósito; luego se aplicó Simulación Secuencial Gaussiana, ejecutando 100 realizaciones en cada UGM y se eligieron aquellas que reproducen mejor las estadísticas de las muestras originales. Los resultados muestran que la litología del depósito controla la variabilidad del BWi y de acuerdo a la competencia de la roca las zonas mineralizadas se clasifican desde la más blanda a la más dura en óxidos, mixtos y sulfuros., The spatial variability in the geometallurgical attributes of the deposits is a crucial parameter from the exploration stage, which conditions and influences the mineral processing. Consequently, the objective of this research is to elaborate the geometallurgical simulation of the Bond Work Index for a porphyry copper deposit. For this purpose, information of primary and response attributes corresponding to ore zones, lithologies and BWi contained in 1,449 samples of exploratory drill holes were used. An exploratory data analysis of this information was carried out, and geometallurgical units were defined based on the geological and processing knowledge that validates the behavior of each one of them within the deposit; then Sequential Gaussian Simulation was applied, running 100 realizations in each GMU, those that best reproduce the statistics of the original samples were chosen. The results show that the lithology of the deposit controls the BWi variability and according to the rock competence the ore zones are classified from the softest to the hardest in oxides, mixed and sulfides.

The agricultural sector can be one of the sectors capable of creating a high number of jobs, but the farmers themselves have the business development of crops into processed products so that they have a high selling value. Most of the farmers in Probolinggo Regency still sell their crops directly without going through further processing, especially for corn. Regulation of the Minister of Agriculture Number: 43/Permentan/OT.140/10/2009, concerning the Movement for the Acceleration of Diversification of Food Consumption (P2KP) Based on Local Resources encourages people to consume diversified non-rice food products, one of which is processed corn products. Therefore, it is necessary to optimize efforts to process corn so as to provide added value to farmers in the form of training to utilize corn yields into innovative and varied new products in order to strengthen food security and increase welfare for farmers. This community service activity was carried out at the Lestari farmer group in Pajarakan District, Probolinggo Regency. The implementation of service activities is in the form of providing training to corn farmers in processing sweet corn into corn chip snacks which have a higher selling value and helping to provide knowledge about online marketing and direct distribution to consumers. The participants gained some knowledge regarding the benefits of added value and also procedures for processing corn into corn chips to add value to a product. Not only did the knowledge increase but the skills of the participants also increased with the training carried out.

Bermgras wordt gemaaid om alles veilig en netjes te houden. Door afval in het gras is het niet geschikt als veevoer. Vaak wordt het gecomposteerd of voor biogas gebruikt. Maar gras bestaat voor dertig tot veertig procent uit cellulose, het hoofdbestanddeel van papier. Onderzoekers van Wageningen UR benutten deze eigenschap in de projecten GO-Grass en MainstreamBIO en maken nu papier van gras.

Previous research has shown that readers experience stronger immersion while reading first-person narratives than third-person narratives, but whether this difference in processing is time-sensitive remains unclear. We report on a self-paced reading experiment in which French participants read short stories in first and in third person. Additionally, participants were directly addressed with either formal or informal second-person pronouns in the final sentence of the narrative, as well as in a subsequent (off-line) questionnaire soliciting post-story immersion reports. The suitability of a particular pronoun of address depends on the social context, and misplaced use can impact the way in which people perceive and assess a particular situation. We did not find significant differences between reading times with first- or third-person pronouns, but participants reported higher immersion and emotional engagement after reading first-person stories than third-person stories. Moreover, the effect of story perspective on reported immersion only occurred when participants were addressed with formal second-person pronouns. We take these findings as evidence for an effect of first- versus third-person pronouns on immersion via perspective shifts. Moreover, we argue that the effect of being addressed with an unexpected (in this case, informal) pronoun can overrule such an effect, while being addressed with an expected (in this case, formal) pronoun can be conducive of it. This finding highlights the importance of research into the impact of pronouns of address.

Ämnet artificiell intelligens har under senaste tiden blivit ett aktuellt diskussionsämne. Utvecklingen har tagit fart de senaste åren och ett tema är hur AI kommer att påverka de olika yrkeskategorierna. Ekonomiskt bistånd fungerar som ett skyddsnät och är en utväg om den enskilde individen inte kan försörja sig på ett annat sätt. Hantering av ekonomiskt bistånd är något som är kommunernas ansvar och det är en handläggare från socialtjänsten som arbetar med den processen. Idag förekommer det att AI-teknologi används inom organisationer, men inom offentlig sektor när det gäller hanteringen av ekonomiskt bistånd har inte den här tekniken tillämpats i någon stor utsträckning. Historiskt sett innan AI kom in på agendan när det gäller användning av IT-teknik har det kretsat kring hur handläggaren interagerar med IT-systemen. Trots att dessa IT-system effektiviserar handläggarens arbete så är fortfarande den mänskliga faktorn en inverkan i handläggningsprocessen. Syftet med den här studien är att undersöka hur AI-tekniken skulle kunna ersätta en människa för att genomföra handläggningsprocessen. I genomförandet av den här studien har kvalitativ datainsamlingsmetod tillämpats. Det har gjorts ett antal semistrukturerade intervjuer med olika kommuner för att undersöka hur de hanterar handläggningsprocessen samt vilka system de använder sig av. Resultatet analyserades mot teori för handläggningsprocessen av ekonomiskt bistånd och grundläggande AI-teknologi. Från resultaten som visar upp hur handläggarna arbetar i de olika kommunerna går det att genom analysen se att det skiljer sig till en viss grad mellan kommunerna. Det som skiljer dem åt är vilka tekniska verktyg handläggarna kan använda sig av för att genomgå processen. Baserat på det går det att dra slutsatsen att AI-tekniken kommer med tiden under dess utveckling att successivt etableras inom handläggningsprocessen för ekonomiskt bistånd., The subject of artificial intelligence has recently become a hot topic of discussion. The development has gained momentum in recent years and one theme is how AI will affect the various occupational categories. Financial assistance acts as a safety net and is a way out if the individual cannot make a living in another way. Management of financial assistance is something that is the responsibility of the municipalities and it is a case manager from the social service who works with that process. Today, AI technology is being used within organizations, but in the public sector, when it comes to managing financial aid, this technology has not been applied to any great extent. Historically, before AI entered the agenda in terms of the use of IT technology, it revolved around how the administrator interacts with the IT systems. Although these IT systems make the work of the case manager more efficient, the human factor is still an influence in the handling process. The purpose of this study is to investigate how AI technology could replace a human to carry out the handling process. In conducting this study, qualitative data collection method has been applied. A number of semi-structured interviews have been conducted with various municipalities to investigate how they manage the handling process and which systems they use. The results were analyzed against theory for the handling process of financial aid and basic AI technology. From the results that show how the case managers work in the various municipalities, it is possible to see through the analysis that it differs to a certain degree between the municipalities. What differentiates them is which technical tools the administrators can use to go through the process. Based on that, it can be concluded that AI technology will gradually become established within the financial aid processing process over time during its development.

Tailings storage facilities have to be monitored with regard to their physical stability to ensurethe safety of the dam and chemical stability to monitor potential environmental impacts.Besides, tailings ponds that accumulated processing rejects over a longer period of time havethe potential to serve as a source for re-processing given that other minerals have become ofeconomic interest or newer, more efficient mineral processing technology has become available. Drilling to the bottom of tailings ponds is usually providing a very valuable data source forall the aspects discussed above. Depending on production technology and mine planning aswell as seasonal and climate effects, hydraulic conditions, mechanical loads etc., the tailingsproperties will differ with time, depth and position. Thus, investigating drill cores is expectedto deliver meaningful vertical profiles of various tailings properties, including information onthe mechanical and mineralogical characteristics of the tailings pond. This project aims to gain further knowledge on the dispersity, mechanical and mineralogicalproperties of the tailings present in Aitik, Boliden. For this purpose, a series of analyticaltests were carried out including the particle size distribution, particle density, particle shapeand shear strength of the tailings on the mechanical side. In addition, x-ray diffraction wasutilized to gain a better perspective on the mineralogical characteristics of the tailings. Lastly,the obtained data were compared with the literature. The aim of the thesis focused on thedifferences in the tailings properties with the potential of a future reprocessing in mind. Asidefrom that, potential links between the mineral beneficiation during production and the changesover time in processing technology were analyzed. The results obtained from the investigations showed a difference from the old processing plantto the new one, which was established in 2010. The samples were taken close to the currentdisch

This thesis examines the manufacturing process of a novel flax fibre polypropylene composite material, focusing on understanding the process and its influencing factors. The composite was manufactured using pre-impregnated twill-woven flax fibre sheets (AmpliTex 5040 – PP) as outer layers and two core layers of pre-impregnated polypropylene sheets reinforced with short, randomly oriented natural fibres (NfPP). The manufacturing process involved preheating the material to core temperatures of 180°C, 190°C, or 200°C, followed by compression moulding with tool gaps of 3.0 mm, 3.2 mm, and 3.4 mm. The study found that the core temperature after preheating did not significantly affect the composite's thickness or layer compaction. However, the tool gap exhibited a significant effect, with an increase in thickness with larger tool gaps. The lowest deviation from the tool gap size was observed at 3.2 mm. The compaction of the AmpliTex 5040 – PP layers demonstrated no dependency on the tool gap, while the NfPP layers exhibited the highest compaction at a gap size of 3.0 mm. Thermal degradation analysis indicated that flax fibre is the most critical component, with higher core temperatures reducing the ultimate tensile strength and fracture strain of the composite material. The maximum tensile properties were observed for materials preheated to 180°C during manufacturing. The manufacturing process demonstrated an improvement in reproducibility compared to previous methods, although substantial variance in thickness remained.

Brain cell structure and function reflect neurodevelopment, plasticity, and aging; and changes can help flag pathological processes such as neurodegeneration and neuroinflammation. Accurate and quantitative methods to noninvasively disentangle cellular structural features are needed and are a substantial focus of brain research. Diffusion-weighted MRS (dMRS) gives access to diffusion properties of endogenous intracellular brain metabolites that are preferentially located inside specific brain cell populations. Despite its great potential, dMRS remains a challenging technique on all levels: from the data acquisition to the analysis, quantification, modeling, and interpretation of results. These challenges were the motivation behind the organization of the Lorentz Center workshop on “Best Practices & Tools for Diffusion MR Spectroscopy” held in Leiden, the Netherlands, in September 2021. During the workshop, the dMRS community established a set of recommendations to execute robust dMRS studies. This paper provides a description of the steps needed for acquiring, processing, fitting, and modeling dMRS data, and provides links to useful resources.

Kinnow fruit processing generates millions of tonnes of citrus waste yearly. This waste, predominantly of bitter-tasting peels, contributes significantly to environmental pollution when discarded. In this regard, the present study utilized kinnow peel waste for making candy, aiming to track down the straightforward, easy method of preparing the kinnow peel candies with extended shelf life. Additionally, it compared physical and chemical processes for removing bitterness from peels to create valuable food industry products, minimizing waste and enhancing fruit value, thus promoting food security with beneficial ingredients. In this laboratory investigation, the peel was treated with nine different treatments (T1: Single boiling, T2: Multiple boiling, T3: Soaking in baking soda, T4: Soaking in Vinegar, T5: Soaking in Alum, T6: Boiling in Salt solution, T7: Boiling in bottle gourd juice, T8: Boiling in cucumber juice, T9: Control-No boiling). The resulting product was analysed for proximate, physicochemical, and organoleptic attributes at 15-day intervals for up to 45 days. The results showed an increase in crude fibre content (4.54-4.61 g/100g), total soluble solids (TSS) (75.14-75.40 0B), pH (2.92-3.07 %), reducing sugar (20.17-20.77 %), total solids (86.67-87.07 %), and total sugar (62.84-63.58 %). At the same time, the decrease was recorded in ash content (0.75-0.59 g/100g), moisture content (13.37-12.60 %), titratable acidity (0.43-0.38 %), ascorbic acid content (11.23-8.97mg/100g), tannins (55.90-55.27 mg/100g), antioxidant activity (44.50-40.71 %), total phenolic content (25.43-22.62 mg GAE 100 g−1), carotenoid content (1.39-1.32 mg/100g), and pectin content (1.50-1.34 mg/100g). The best treatment was T2, which involved multiple boiling, cooking in 75 0B sugar syrup solution, and saturating with sugar syrup for 24 hours. It had desirable proximate, physicochemical and organoleptic properties and was stable for up to a minimum of 45 days for storage.

Nutrition and health are gaining significant focus as people seek convenient, nutrient-rich food options. Food processing must be efficient, cost-effective, and durable to meet these demands. Transforming fruits into diverse products using affordable technology can boost the economy for farmers and the nation. Fruit-based goods with high potassium and low salt offer substantial dietary benefits, making them valuable to health-conscious consumers.The present study aimed to study different value-added products from fruits and to increase their shelf life. Perishable fruit has losses during postharvest changes. Different strategies are required to avoid such losses. One method is to transform fruits into value-added goods. The transition of a raw resource or commodity into a processed product by combining raw materials, labour, time, and technology to produce a higher financial return is known as value addition in fruit processing. It focuses on ending hunger, achieving food security, improving nutrition, and promoting sustainable agriculture. Value-added fruit products can contribute to food security by achieving sustainable goals of good health and well-being. The study concluded that value-added fruit products play a vital role in the food industry, benefiting both producers and consumers. They reduce food waste, provide economic opportunities for farmers, and offer consumers convenient, nutritious, and flavourful options. The value-added fruit product market will likely further,contributing to the agricultural sector’s sustainability and worldwide consumer well being. This review details the value-added products in fruits.

Insectenmeel en biologisch melkweipoeder zijn potentieel veelbelovende grondstoffen voor pluimveevoeders door onder meer hun nutritionele waarde, regionale oorsprong en bijdrage binnen het concept van circulaire landbouw. Zowel insectenmeel als melkweipoeder bevatten hoge gehaltes aan methionine en vitamine B2, twee componenten die zeer belangrijk zijn in het rantsoen van leghennen. Binnen de biologische veeteelt is het niet toegestaan om synthetische aminozuren of vitamines in het voeder toe te voegen, waardoor de gehaltes ervan vaak moeilijk op peil te houden zijn.

Terwijl de insectenteelt voor dierenvoeding zich stillaan succesvol ontpopt, heeft de mentaliteitsverandering om mensen insecten te laten eten meer tijd nodig. “Voeding blijft een heel gevoelig thema”, beamen Michiel en Anneleen Van Meervenne, oprichters van KRIKET die zoete en zoute snacks op basis van krekelpoeder op de markt brengen.

Due to the increased popularity of plant-based products, new alternatives for animal-derived products are being developed. Before market introduction, food business operators (FBOs) should identify food safety hazards for these plant-based products to protect consumer health. A wide range of chemical hazards may be present in the ingredients used for these products. Ranking the hazards will help FBOs to focus on the most relevant ones and identify the most optimal recipe for such products. This study provides a two-tiered ranking approach. First, all potential hazards were identified based on their presence in the crop, detection above European Union (EU) legal limits, data gaps, and potential health risks. Second, a risk ratio method was applied for the most relevant hazards based on the chemical hazard in the crop, processing factors to establish (protein) ingredients, consumption data, and health-based guidance values. This structured approach was applied to a case study on plant-based burgers using five example recipes, which showed it was capable of comparing various recipes and indicated an optimal recipe to produce plant-based burgers with minimised food safety risks. As such, it can be used as a safe-by-design approach in the early development of new plant-based alternatives.

Scalable processing of thin and robust solid-electrolyte (SE) separators is key for the commercialization of high-energy all-solid-state batteries (ASSBs). Herein, we report the preparation of Li6PS5Cl-based thin SE separators incorporating suitable binders for potential use in ASSBs by two scalable wet processing techniques: tape-casting with nitrile-butadiene rubber (NBR) and calendering with carboxylated nitrile butadiene rubber (XNBR). By means of tensile testing and electrochemical impedance spectroscopy, the influence of processing on the mechanical as well as the electrochemical properties of the resulting thin SE separators is investigated. A trade-off between the mechanical and electrochemical properties is observed, which is due to the inextricably linked microstructures (particle size, binder content and distribution, and porosity) induced by the two different processes. Thin SE separators prepared using the tape-casting method with the more well-distributed binder network demonstrate superior tensile mechanical properties compared to the ones prepared by the calendering method. The results provide insights into the processing-structure-property relationships of the thin SE separators, which will contribute to advancing the application of practical thin solid electrolytes in ASSBs.

Fluid gels are jammed suspensions of gelled particles widely used across several industries to functionalise materials. They can be obtained for example by applying shear to a gelling hydrocolloid during its sol-gel transition. In the present study, the impact of flow rate, modulated by applying different processing stirring speeds under constant geometrical parameters, on the rheology, particle morphology and physical ageing of low acyl gellan gum fluid gels was investigated. Fluid gel particle elongation was observed in samples processed at higher stirring speeds whereas, no decrease in particle size was measured. The increase in aspect ratio is attributed due to the flow rate experienced by the particles through the geometry used to manufacture the samples. Fluid gels processed at higher stirring speeds generally showed lower low-shear viscosity, elastic modulus and higher yielding properties and interconnectivity. This might be due to the elongation of the fluid gel particles which would decrease particle voluminosity but increase the likelihood of mechanical entanglement, increasing their viscous dissipation. In addition, samples manufactured at higher stirring speeds exhibited a G′ increase with the number of shear cycles performed whereas, samples processed at lower stirring speeds showed a G′ decrease with the number of shear cycles performed. This behaviour might be caused by the balance between two counteracting mechanisms: abrasion (decrease in G′) and compaction (increase in G′). In addition, the higher the stirring speed the higher the ageing exponent. This might be due to the larger surface area of elongated particles which might ease interparticle link formation. Furthermore, the impact of the gravitational field on the physical ageing of low acyl gellan gum fluid gels was investigated by entrapping silica microparticles within the fluid gel particles, allowing tuning the density difference between the continuous and dispersed fluid gel phases.

This study outlines a recycling initiative conducted at Rekular GmbH, focusing on the recycling of 100 refrigerators. The recycling process employed a combination of manual dismantling, de-pollution, and mechanical processing techniques. Manual dismantling followed a predefined protocol to extract various materials, while the mechanical and physical processes involved Shredding, Zigzag, Magnetic, and Eddy Current Separation (ECS) to liberate and separate differ-ent materials. The resulting ferrous, non-ferrous and polymer product fractions were analyzed and categorized, providing valuable insights into the quality of interim products in the refrigera-tor recycling process. Simulations were then performed using FactSageTM and HSC Chemistry software to simulate the recovery of metals from the ferrous and non-ferrous fractions using pyro metallurgical and hydrometallurgical methods. An Electric Arc Furnace (EAF) was utilized for iron (Fe), while a Re-smelter process for aluminium (Al), and the Black Copper Route was simu-lated for copper (Cu) recovery. The recovery rates including metallurgical, mechanical, and physical processes are as follows: Fe (78%), Al (68.4%), and Cu (52.4%). In contrast, the recovery rates through metallurgical processes are as follows: Al (99%), Fe (79%), and Cu (88%). This dis-crepancy is attributed to losses of these elements resulting from incomplete liberation in mechan-ical processing. Additionally, a Product/Centric approach was applied and the recycling index reached 76% for recovery the Al, Cu, and Fe metals in a refrigerator recycling process. Turning to the environmental impact evaluation within the Life Cycle Assessment (LCA), the process unit with the highest emissions per refrigerator in the recycling process was the use of nitrogen dur-ing the shredding process, accounting for 3.7 kg CO2 eq/refrigerator. Subsequently, the con-sumption of medium voltage electricity from the German grid during mechanical and physical separations co

Natural fibers are promising bio-based materials to use as reinforcements in polymer composites as often more affordable and accessible alternatives to fossil-based fibers, especially because of their superior sustainability. Polyoxymethylene (POM) is a widely used engineering thermoplastic, which has a melting temperature suitable for processing with natural fibers. In this study, such composites consisting of POM and regenerated cellulose fibers have been developed and studied in terms of their mechanical, thermal, tribological and structural properties. Tensile and flexural moduli increased with incorporation of 30 wt% fibers up to 89% and 79% respectively, crystallinity increased as well by a maximum of approx. 11% at 30% fiber content. Furthermore, the specific wear rate was improved for the composite with 10 wt% fibers, showing a decrease of roughly 80%. This study investigates the processing parameters and tribo-mechanical performance of POM-based natural fiber composites as an important route towards future sustainable polymer composites in load bearing applications., Validerad;2023;Nivå 2;2023-11-08 (marisr);License fulltext: CC BY-NC-ND

In this study, we demonstrate the significance of austenite annealing twin boundaries when calibrating laser ultrasonic measurements for gauging austenite grain size in situ during the thermomechanical processing of high-strength low-alloy steels. Simple calculations show how differences in twinning density can lead to errors in grain size measurements if twins are disregarded during calibration and the method is used for a broad range of steels. Conversely, when calibration is performed using alloys with a metastable austenite microstructure at room temperature, the same calibration is suitable for a broad range of HSLA steels, provided that annealing twins are taken into account. Since light optical microscopy does not allow the characterization of annealing twins in low-alloy steel, the verification of the laser ultrasonic results was conducted using the novel approach of comparing the twinned grain sizes obtained using the ultrasonic method in low-alloy steels with the austenite grain maps reconstructed from martensite orientation maps measured using electron backscatter diffraction. Finally, we show how differences in twinning density occur even for alloys with a roughly similar stacking fault energy, further highlighting the importance of annealing twins in the calibration of laser ultrasonic measurements for industrial use., QC 20231030

Aspergillus fumigatus is een schimmel die van nature voorkomt in dood plantenmateriaal en die daarnaast infecties kan veroorzaken bij patiënten met specifieke aandoeningen. Wanneer patiënten worden geïnfecteerd met A. fumigatus die resistent is tegen azolen wordt de behandeling ernstig bemoeilijkt. Recent onderzoek heeft uitgewezen dat het gebruik van azolen in niet-medische toepassingen leidt tot een toename van azoolresistente A. fumigatus op verschillende plekken in het milieu, in zogenaamde hotspots. Het is de vraag of de praktijk van circulair terreinbeheer waar maaisel en blad wordt verzameld om te worden bewerkt tot organische bodemverbeteraar zo’n hotspot is. Het maaisel en blad kan namelijk in aanraking zijn geweest of behandeld zijn met azolen en zou (hoge) fracties azoolresistente A. fumigatus kunnen bevatten. Het concrete doel van dit onderzoek is om eventuele risico’s van resistentieontwikkeling in A. fumigatus in de diverse groenreststromen (maaisel en blad) die verwerkt worden bij de pilots van het kennisprogramma Circulair Terreinbeheer te inventariseren en in kaart te brengen. Indien mogelijk gebruiken we de resultaten om adviezen te formuleren om mogelijke risico’s te voorkómen en/of significant te verlagen. Hierbij is gekeken naar de eventuele effecten die bewerkingsmethoden zoals Bokashi en compost-O hebben op de aanwezigheid, groei en resistentieontwikkeling van A. fumigatus.

Coconut palm has significant position in the life of Indonesian people as it provides various products and by-products useful in their daily life. The main product is derived from coconut meat which can be produced into copra. The study aimed to assess value addition in copra production and to determine the factors that affect value addition in copra production. This research was carried out in Mawasangka Subdistrict, Central Buton District, Southeast Sulawesi Province. The population in this study was 51 copra producers. Respondents were determined using the census method through which the entire population was selected as respondents. Hayami method of production structure was used to calculate value addition, whereas multiple linear regression was employed to determine the factors affecting value addition. Study results showed that the average value added of copra production was IDR749.38/kg of raw materials. The regression results revealed that all independent variables, namely, the number of coconuts, labor wages, copra prices, coconut prices, and other inputs, jointly had a significant effect on the value added. Partially, the copra price, coconut price, and other input contribution had a significant effect on the value added, while other variables did not.

The problem of enumerating subgraphs satisfying some properties (e.g., patterns and mo- tifs) corresponds to listing such subgraphs. In general, because of the large/huge graphs re- lating objects in different domains (biology, mobile networks, social networks, genetics, etc.), waiting until achieving the whole enumeration of subgraphs satisfying some properties can be too expensive and unmanageable for some families of problems. Thus, the possibility of incrementally enumerating these subgraphs (i.e., a subgraph is returned as soon as they are identified) rises as a promising approach for some families of problems (e.g., network analysis and motif identification). In effect, following a search approach over the listed subgraphs allows stopping the enumeration when it is convenient. The implementation of incremental enumer- ation solutions suits well to stream processing paradigms and frameworks. In this work, as a proof of concept, we conduct a comparative study of the continuous behavior of two stream processing-based solutions for the problem of incrementally enumerating weakly connected components of (bounded) undirected graphs. One of these solutions is implemented using the Go programming language following the Dynamic Pipeline Paradigm, and the other solution is implemented on top of the DataSet API provided by the Apache Flink Framework. Finally, we analyze and report experiments against large graphs having up to 2, 746 connected compo- nents. Obtained results satisfy our expectations. To assess the incremental delivery of results, we measure the the diefficiency metrics, i.e., the continuous efficiency of the implementation of the algorithm for generating incremental results., El problema de l'enumeració dels subgrafs que satisfan determinades propietats (per exem- ple patrons i disenys) correspon a la mostra d'aquests subgrafs. En general, a causa dels grafs grans/enormes que relacionen objectes en diferents dominis (biologia, xarxes mòbils, xarxes socials, genètica, etc.), esperar fins a aconseguir l'enumeració sencera dels subgrafs que satisfacin certes propietats pot ser massa costós i immanejable per a algunes famílies de problemes. Per tant, la possibilitat d'enumerar incrementalment aquests subgrafs (es dir, enumerar els com- ponents a mesura que es calculen o s'identifiquen) sorgeix com una alternativa prometedora per a algunes famílies de problemes (per exemple, en l'an'alisi de xarxes i en l'identificació de patrons). En efecte, seguir un enfocament de cerca sobre els subgrafs enumerats permet aturar l'enumeració quan sigui convenient. La implementacióde solucions d'enumeració incremental s'adapta bé als frameworks i paradigmes de processament de fluxos de dades. En aquest tre- ball, com a prova de concepte, realitzem un estudi comparatiu del comportament continu de dues solucions basades en el processament de fluxos de dades per al problema de l'enumeració incremental de components d'ebilment connexes de grafs (acotats) no dirigits. Una d'aques- tes solucions s'implementa utilitzant el llenguatge de programació Go seguint el Paradigma de Dynamic Pipeline, i l'altra solució s'implementa sobre l'API de DataSet proporcionada per l'Apache Flink Framework. Finalment, analitzem i informem sobre experiments realitzats amb grafs grans que contenen fins a 2746 components connexes. Els resultats obtinguts satisfan les nostres expectatives. Per avaluar el lliurament incremental de resultats, mesurem les mètriques de dieficiència, es a dir, l'eficiència continua de la implementació de l'algorisme per generar resultats incrementals.

The superior biocompatibility and biodegradability of polyhydroxyalkanoates (PHAs) compared to man-made biopolymers such as polylactic acid promise huge potential in biomedical applications, especially tissue engineering (TE). Textile fiber-based TE scaffolds offer unique opportunities to imitate the anisotropic, hierarchical, or strain-stiffening properties of native tissues. A combination of PHAs' enhanced biocompatibility and fiber-based TE scaffolds could improve the performance of TE scaffolds. However, the PHAs' complex crystallization behavior and the resulting intricate spinning procedures remain a challenge. This review focuses on discussing the developments in PHA melt and wet spinning, their challenges, process parameters, and fiber characteristics while revealing the lack of an in-depth fiber characterization of wet-spun fibers compared to melt-spun filaments, leading to squandered potential in scaffold development. Additionally, the biomedical application of PHAs other than poly-4-hydroxybutyrate is hampered by a failure of polymer purity to meet the requirements for biomedical applications.

This is a material driven study that explores how post-processing of a 3D-printed biocomposite may increase its utility in the public furniture industry. The study thereby aims to contribute insights in material development and inspire a shift in practices that pushes the industry towards a more sustainable design process. By studying theories on sustainable development, biocomposites, and additive manufacturing, the surface defects in large-scale 3D-printing are put in relation to the industry-specific requirements placed on public furnishings. The potentials for the biocomposite to satisfy these demands are assessed using the four actions steps of material driven design. This includes hands-on exploration of several post-processing methods to minimize the material’s distinctive surface roughness. The most effective surface treatment, a combination of subtractive and additive processing, is subsequently applied in a product development phase to exemplify the feasibility of these methods in the context of furniture. This resulted in a design concept which, although a time-consuming process, proves the possibility of post-processing to influence the ability of the material to meet the requirements for public use. The increased material utility achieved in this study should, however, be considered relative to the economic and ecological consequenses associated with biocomposite processing.

To address environmental and social harm caused by fast fashion and the industrial textile economy, locally produced, sustainable fibre has become an increasing trend around the world. In Manitoba, the Pembina Fibreshed exists to connect local fibre producers, artisans, and consumers, and to educate people on where their clothing comes from and how it is produced. One initiative the Pembina Fibreshed has undertaken to achieve their mission is the Flax to Linen project. The goal of the Pembina Fibreshed is to determine whether it is possible to grow flax and produce linen in Manitoba. Due to the project being done at a grassroots, community level, the Flax to Linen Valuation project was developed in the project’s first year with the Pembina Fibreshed, as project partners, to support the documentation of their efforts to grow flax and produce linen. The Flax to Linen Valuation project provided information to the project partners so that they could determine the best way to move the project forward in subsequent years. Specific objectives for the practicum project were: to review existing knowledge on growing fibre flax and linen production; to facilitate a participatory assessment of flax growing and linen production with community members; and to document the project stages and processes. To achieve these objectives, deliverables were produced which consisted of briefing emails to project partners, a participatory assessment guide for project participants, a valuation report of the project providing feedback to organizers from project participants, and a photo narrative book providing a visual and narrative documentation of the project featuring participant voices. Methodologies to produce these deliverables included a literature review, participatory observation, and semi-structured interviews. Two deliverables that demonstrated the most value to the project were the valuation report and photo narrative book. These deliverables have worked to guide and improve the F

Lignocellulosic biomass is the most abundantly available resource in nature. However, its potential as a replacement of oil in plastic production has not been fully exploited. To reduce the carbon footprint, the use of lignocellulose biomass to produce bio-based plastics is attracting increasing global interest. The aim of this review article is to systematically summarize the recent advancements of the development of lignocellulose materials that possess thermoplastic properties, meaning they can be processed/shaped by common plastic processing techniques. The approaches used for modification of lignocellulose biomass and the properties of the modified materials, as well as factors affecting the properties of these, are discussed. The regulatory aspects and policy directions of bio-based plastics, including thermoplastic lignocellulose, are also mentioned. Current challenges of producing thermoplastic lignocellulose and the way forward to solve this are also explored., QC 20231122

Syftet med detta examensarbete var att undersöka möjligheten till kameraövervakning i processen för att förenkla avvikelsehanteringen samt att ta fram en teknisk lösning till detta. Det finns många fördelar med kameraövervakning i processerna, bland annat att kunna se vad som händer inne i maskinerna och genom detta ha möjlighet att analyserna cykeltider och få bättre kännedom om processen. För att få reda på i vilket utsträckning kameraövervakning i processerna är tillåtet hölls ett möte med en förhandlingsledare för fackförbundet If metall. Resultatet av mötet var positivt, det krävs en MBL-förhandling för att dokumentera syftet, som inte får vara att övervaka medarbetarna. Genom intervjuer kunde det fastställas vad medarbetare krävde av systemet och för att få en bild över vad det finns för kameralösningar på marknaden gjordes studiebesök och benchmarking. En lösning kunde sedan väljas ut och valet landade på mjukvara och hårdvara från kameraföretaget Axis. Slutsatserna av examensarbetet är att kameraövervakning i bearbetningsprocesser skulle bidra till fler utredda avvikelser i maskinparken, en stabilare process och ett säkrare logistikflöde världen över., Volvo Group Trucks Operation is a world-leading company in the trucking industry. The engines for trucks and buses, among other things, are manufactured at the Volvo factory in Skövde. The purpose of this thesis was to investigate the possibility of implementing camera monitoringin the process to simplify deviation management and develop a technical solution for it. There are advantages to camera monitoring in the processes, such as being able to see what is happening inside the machines and, through this, being able to analyse cycle times and gain a better understanding of the process. To determine the extent to which camera monitoring in the processes is allowed, a meeting was held with a negotiation leader from the labor union If Metall. The result of the meeting was positive, and it was determined that an agreement under the Co-Determination Act (MBL) is required to document the purpose, which should not be to monitor the employees. Through interviews, the requirements of the employees for the system were established, and to gain an overview of the camera solutions available on the market, site visits and benchmarking were conducted. A solution was then chosen, and the selection landed on software and hardware from the camera company Axis. The conclusion of the thesis is that camera monitoring in the machining processes would contribute to a higher number of investigated deviations in the machine park, a more stable process, and a safer logistics flow worldwide.

During the last century, various countries' armed forces have used unmanned aerial vehicles, commonly known as drones. In recent years, strives have been made to develop small commercial drones that have allowed the general public to afford and use them for recreational purposes. The availability of drones has led to immoral applications of the technology. Such applications need to be faced with anti-measures and effective detection methods. Therefore, this thesis aims to develop a mobile reconnaissance robot that can detect commercial drones with radar. It describes integrating radar sensors with single-board computers to detect and localise air-bound objects. The finished product aims to be used for educational and exhibition purposes at the Swedish Armed Forces technical school to increase awareness of the technology., Försvarsmaktens tekniska skola i Halmstad var intressenter för uppsatsen.

Dadurch sollen wertvolle, wissenschaftliche Erkenntnisse generiert werden. Der Fokus liegt dabei auf Endkunden in Deutschland, Österreich und Schweiz. Des Weiteren wird im Zuge der Medienkonvergenz, der Digitalisierung und eines veränderten Mediennutzungsverhaltens die Automobilwerbung analysiert: Im Zentrum dieser Betrachtung stehen die Bedeutungsrelevanz im Automobilmarketing, die Verortung von werbepsycho-logischen Erfolgsfaktoren und der Einfluss strategischer Positionierung in Bezug auf den Werbeerfolg. Die systematische Literaturanalyse stützt sich auf wissenschaftliche Nachbarbereiche der Werbung und auf die Betrachtung komplexer, werblicher Prozesse. Modelle aus interferierenden Fachdisziplinen des Marketings, Konsumentenverhaltens und der Werbepsychologie kommen hier zum Einsatz. Die empirische Untersuchung wird durch die Methode der deskriptiven Statistik von Endkunden und Experten anhand eigener, quantitativen Online-Befragungen durchgeführt und bringt Erkenntnisse sowohl für die Medienwissenschaft als auch die Praxis hervor. Die Herausforderung in dieser Dissertation besteht darin, die komplexen Interferenzen der Fachdisziplinen im Kontext dieser Arbeit aufzunehmen und in einer Annäherung der Allgemeingültigkeit erfolgsorientiert offenzulegen. Obwohl Werbung aufgrund der gesellschaftlichen und technischen Transformationen auch künftig einem starken Wandel unterzogen sein wird, ist sie innerhalb des Automobilmarketings immer noch von großer Relevanz., The aim of the dissertation entitled "The role and importance of advertising in automotive marketing" is, to combine perspectives of theory and empiricism in relation to customers in Germany, Austria and Switzerland and using the perspective approach of experts from the automotive industry, the car trade and the creative industries in order to generate scientific insights. Furthermore, in the course of media convergence, digitization and changed media usage behavior, automotive advertising is now analyzed with regard to the relevance of meaning in automotive marketing, the location of advertising psychological success factors and the influence of strategic positioning with regard to advertising success. The systematic analysis of literature is based on the scientific neighbouring areas of advertising and the consideration of complex advertising processes and models from interfering disciplines of marketing, consumer behavior and advertising psychology. The empirical study is carried out using the method of descriptive statistic of end customers and experts by means of their own quantitative online surveys and is intended to produce insights for media studies and practice. The challenge in this dissertation is to record the complex interferences of the disciplines on one hand and to reveal them in a success-oriented approach to the generality on the other hand! Advertising is of central importance to automobile sales and marketing. It will continue to evolve and change in the future due to processes related to social and technical transformation., Claus Hutter, Dissertation Universität Innsbruck 2023

Polycyclic aromatic hydrocarbons (PAHs) are amongst the most toxic compounds known to man. Several PAHs are proven to be carcinogenic, mutagenic, and teratogenic. Due to their wide distribution in the environment and their toxicity, it is considered important to monitor the levels of these compounds in foodstuffs. PAHs have been detected in many food products including plant-based such as vegetable oils, cereal grains, herbs, spices, teas, and supplements1,2. As the awareness of the healthy lifestyle has increased globally, the intake of medicinal herbs such as teas and spices has also grown immensely. Therefore, an even bigger emphasis must be made to monitor the toxic levels of PAHs in herbs. The maximum concentrations of certain contaminants in food in the Republic of Serbia included PAHs values in dry herbs only by the end of 2019 ("Official Gazette / RS", No. 81/2019)3. Herein, were investigated the sources of PAHs contamination in dry herbs collected from the different parts of Serbia, its quantification and the potential health risk posed by their toxicity.
