Abstract:
The effect of hot multistage drawing conditions on the structure and properties of nylon 6 fibers was investigated by varying second stage draw ratio. Total draw ratio was changed from 3.3 to 5.775 to clarify the structural changes in nylon 6 fiber at a broad range of draw ratio. The structural development of the fibers was studied with FTIR spectroscopy, differential scanning calorimetry (DSC), optical microscopy, and tensile testing. A continuous drop of the γ crystalline form content is observed as a function of draw ratio, in parallel with an increased content of α crystalline phase. The γ crystalline phase vanished completely at draw ratio of 4.62. Increasing draw ratio caused an increase in birefringence and no significant change occurred in crystallinity for the drawn nylon 6 fibers. Deformation behavior of drawn nylon 6 fibers has been explained in terms of applied thermal treatment and mechanical deformations which occurred in each step of multistage drawing.

Abstract:
This paper argues that the vertical spread of computer-assisted language learning (CALL), i.e., a spread throughout language materials and curricula, makes it difficult to draw a clear distinction between CALL and other language materials. In view of the emphasis that teachers, researchers, and administrators have placed on evaluating CALL, I argue that some valuable lessons about materials evaluation can be drawn from reflection on issues in CALL evaluation. In particular, I discuss the opportunities for professionals to reconsider assumptions held about comparative research, draw upon research perspectives and methods from applied linguistics in materials evaluation, and include critical perspectives which examine the opportunities that materials offer language learners to engage in language and culture learning.

Abstract:
Concave/convex wall features are usually generated in the deep-drawn parts with complicated geometry, especially the difficult-to-deep draw materials. The application of the draw bead could reduce the concave/convex wall features. However, it is difficult to determine the suitable draw bead geometry and its position to obtain a straight wall. In this study, the effects of draw bead height were investigated using the finite element method (FEM) and experiments. The application of the draw bead and the effects of its height on the concave/convex wall features could be theoretically clarified on the basis of principal stress distribution. The application of draw bead led to the decrease in tensile stress in the direction of punch movement and also increased in the tensile stress distributed to the corner zone; therefore, the concave wall feature decreased. In addition, this feature decreased as the draw bead height increased. However, the application of a very large draw bead height resulted in a convex feature. The FEM simulation results were validated by experiments in the following two cases, i.e., without and with draw bead formations. With reference to the material thickness distribution, the FEM simulation results showed a good agreement with experimental results.

The mechanical yielding and necking behaviors of metallocene-catalyzed high density polyethylenes were investigated from a structural point of view. In particular the natural draw ratio was investigated with different crosshead speeds, molecular weights, and the cross-section shapes of sample specimens. We proposed a structural model for explaining the necking formation in addition to the molecular weight and the cross-sectional shape dependences of the natural draw ratio.

Abstract:
HDPE-based nanocomposite fibers have been extruded from a melt and drawn up to draw ratio DR = 8. Two kinds of carbon nanodiscs (original ones and those exposed to additional annealing) have been used as fillers. Obtained nanocomposite fibers have been investigated with the help of different experimental methods: rheology, SEM and WAXS. It has been demonstrated that the annealed carbon nanodiscs possess a nucleation ability that finally leads to strong transformation of the material morphology.

Abstract:
The process, structure, and property relationship of PAN fiber as a precursor to carbon fiber was studied. The limitations of stable spinning and property improvement associated with hot draw in solution spinning were found and quantified. Conditions were varied to generated precursor fiber up to the limit of draw, from which actual samples were collected for thermal conversion to carbon fiber. Samples of PAN and subsequent carbon fiber were characterized using tensile testing and x-ray analysis. The effects of draw on modulus and break stress, as well as the orientation of the crystalline structure of both parent precursor and resultant carbon fiber were found and related back to the quantified draw limit.

Abstract:
In diesem Paper werden Untersuchungen eines Tiefziehwerkzeugs aus Mineralguss vorgestellt. Der Grund für die Verwendung von Mineralguss als alternativen Werkstoff für schnelle Werkzeuge liegt in den relativ geringen Initialkosten zur Herstellung und seiner Eignung für Kleinserien und Prototypenversuche. Ähnliche Konzepte mit Werkzeugen aus Mineralguss haben gezeigt, dass eine entscheidende Grenze in der Tribologie und dem bei diesem Werkstoff großen Oberflächenverschleiß liegt. Daher fokussiert das vorliegende Paper auf die Ergebnisse der Analyse verschiedener Mineralgussmischungen unter Anwendung von Streifenzugbiegeversuchen. Die Reibzahl wurde hierbei berechnet und vergleichend einem Stahlwerkzeug gegenübergestellt
This paper presents the investigation of polymer concrete drawing tools for deep drawing operations. The goal of using polymer concrete as an alternative material is a rapid tooling process at relatively low initial tools costs that is suitable for small batch production. Similar concepts based on hydraulic concrete and polymer composites have shown that the surface tri-bology and consequently wear is the main limiting factor. Therefore, this paper focusses on the results of strip draw-bending tests with different polymer concrete mixtures. The friction coefficient is calculated and compared to a steel tool

Abstract:
To model shrink-fitting in metal components, an analytical model for two long compound cylinders with temperature dependent material properties and interference between them is developed for calculating transient temperatures and stresses. A finite element model is developed for the same geometry which incorporated the temperature dependent material properties. A convergence study is performed on the finite element and analytical model. The finite element model is validated by comparing the approximations of finite element model with the analytical solution. In an assembly procedure of fulcrums for bascule bridges, called AP1, the trunnion is shrink-fitted into a hub, followed by shrink fitting the trunnion-hub assembly into the girder of the bridge. In another assembly procedure called AP2, the hub is shrink-fitted into the girder, followed by shrink-fitting the trunnion in the hub-girder assembly. A formal design of experiments (DOE) study is conducted on both AP1 and AP2 using the finite element model to find the influence of geometrical parameters such as radial thickness of the hub, radial interference, and various shrink-fitting methods on the design parameter of overall minimum critical crack length (OMCCL) - a measure of likelihood of failure by cracking. Using the results of DOE study conducted on both the assembly procedures, AP1 and AP2 are quantitatively compared for the likelihood of fracture during assembly. For single-staged shrink-fitting methods, for high and low hub radial thickness to hub inner diameter ratio, assembly procedure AP1 and AP2 are recommended, respectively. For fulcra with low hub radial thickness to hub inner diameter ratio and where staged shrink-fitting methods are used, for AP2, cooling the trunnion in dry-ice/alcohol and heating the girder, and for AP1, cooling the trunnion-hub assembly in dry-ice/alcohol followed by immersion in liquid nitrogen is recommended. For fulcra with high hub radial thickness to hub inner diameter ratio and where staged shrink-fitting methods are used, cooling the components in dry-ice/alcohol and heating the girder is recommended for both AP1 and AP2. Due to the limitations of AP2, assembly procedures by heating the girder with heating coils instead of dipping an already stressed trunnion-hub assembly in liquid nitrogen are studied for decreasing the likelihood of failure by cracking and yielding. In an assembly procedure called AP3-A, only the girder is heated to shrink-fit the trunnion-hub assembly in the girder. This assembly procedure AP3-A is found to be infeasible because the girder fails by yielding if heating is expected to be completed in a reasonable amount of time. An alternative assembly procedure called AP3-B is suggested for shrink-fitting where the heating of the girder is combined with cooling the trunnion-hub assembly in dry-ice/alcohol mixture. This assembly procedure AP3-B is found to be feasible. A complete DOE study is conducted on AP3-B to find the influence of parameters like hub radial thickness and radial interference at trunnion-hub interface on the design parameter of overall minimum critical crack length. The design parameter, OMCCL values during the assembly procedure AP3-B are quantitatively compared with the widely used assembly procedures (AP1 single-stage shrink-fitting and AP1 multi-staged shrink fitting). The results of this work suggest that increasing the hub radial thickness decreases the likelihood of fracture significantly. For hubs with large radial thickness, heating the girder combined with cooling the trunnion-hub in dry-ice/alcohol mixture (AP3-B) is recommended but for hubs with low radial thickness, multistage cooling of the trunnion-hub assembly in dry-ice/alcohol mixture followed by dipping in liquid nitrogen (AP1- multistage cooling) is recommended.

The preform-to-fiber thermal drawing method is a versatile process that allows the fabrication of polymer or glass-based fibers with complex multimaterial internal structures, which grant them functions ranging from optical transmission to chemical detection. However, while a wide range of materials have been successfully drawn in various phases - such as metals, semiconductors, and ferroelectric polymers - the overall structure of the fiber is typically axially-invariant and the incorporation of heterogeneous materials with isotropic microstructures such as porous domains has remained elusive thus far. In this thesis we investigate the use of in-fiber phase separation as a means to control the microstructure of different components within thermally-drawn fibers. In particular we propose a novel method based on controlled phase separation of a polymer solution that we use to embed isotropically porous polymeric domains inside multimaterial fibers. We achieve this by thermal-drawing a hollow polymer preform filled with a liquid polymer solution in its core. We later apply this method to the fabrication and characterization of scaffolds for neural regeneration. In addition, we show that the same principle can also be used to draw a functional lithium-ion fiber battery; a fiber device capable of electrochemical energy storage. Finally, we demonstrate how to produce structured Si-Ge spheres encapsulated within a silica cladding by inducing capillary breakup of a continuous Si-Ge core fiber in a strong axial thermal gradient. The thermal gradient causes a "kinetic phase separation" of the alloy, leading to structured Janus particles.

Abstract:
Biaxial orientation of PET for the production of high strength films for demanding applications, such as slot liners for electrical motors and sound and audio visual tapes, is a well established process. More recently biaxial orientation of PET has been utilised for the production of carbonated beverages, bottles and cans for processed food packaging to achieve high strength and impact resistance. These containers, however, are not suitable for hot filling and high temperature sterilization purposes owing to the lack of dimensional stability.

Abstract:
AbstractThe development and functioning of representations of God are complex processes, in which psychological and cultural factors mutually influence each other. Attachment is a psychological factor that can provide insights into the representation and communication of ideas and experiences regarding supernatural agents in children’s drawings and narratives. Our hypotheses: (1) Securely attached children will use more God representation-related symbols in their drawings than insecurely attached children, (2) These symbols will have a referring and self-transcending character. We explore children’s drawings of God and their accompanying narratives with regard to attachment styles. We describe our theoretical framework and discuss the research process, our use of theory and materials, and our findings. We also present a qualitative analysis of drawings by both insecurely and securely attached children, focusing on qualitative aspects of the drawings and their use of religious symbols. Secure attachment is associated with more God representation-related symbols. Other drawing aspects also relate to attachment. We compare the occurrence of attachment characterizations of relationships with God, the padding of the paper, and the use of anthropomorphic and non-anthropomorphic images. Finally, we focus on the concrete localization of God on the paper, and the figurative place where children imagined God to be.

AbstractTo conclude this stage of research on the representations of supernatural agents in children’s drawings, this chapter summarizes some of the main results of the works collected in this volume. The use of drawings to study children’s representations is not a classic methodology in child psychology. Analysing images is challenging on different levels: content analysis, material features of the drawings, and the development of technical tools needed for the analysis. This chapter discusses the benefits and the limitations of this methodology, as well as those of interdisciplinary approaches that try to combine computer vision methods with studies on child and adolescent development. It ends with the presentation of specific research ideas generated by this first stage of investigation, ideas which we propose as a program for a second stage of research.

AbstractAs data sharing and preservation become a major concern in the humanities and social sciences, more and more scholars are lead to produce, organize, and/or manage digital infrastructures. What we call “data equipment” is a major aspect of such work. Our study draws on an ongoing ethnographic inquiry into the Children’s Drawings of Gods project, focusing on the production and organization of the project database. We describe how the drawings are “equipped,” i.e. how entities are added to the original material and transformed in order to make the data usable and sharable at different scales. We document the constitution of the data (production and recollection of drawings and metadata, production of further metadata) and the transformation of the drawings during this process. Doing so, we show some important aspects of the project regarding the building of its digital infrastructure.

Abstract:
A novel sheet metal forming technology based on aspects of both warm forming and superplastic forming has recently been developed. The new forming process, referred to as hot draw mechanical preforming (HDMP), uses two sequential steps to form a panel within a single tool at elevated temperature. In the first step, the cushion system acts on a binder and upper die to draw the blank over a punch which serves to draw in metal from the perimeter of the blank. In the second step gas pressure is applied to finish the panel details. This two step process of drawing in metal followed by gas forming can result in a significant expansion of the forming envelope for conventional AA5xxx series aluminum sheet alloys commonly used within the automotive industry. Similar to SPF, the HDMP process is performed within a single forming press equipped with heated platens and using gas pressure to shape the component during elevated temperature forming. However, the HDMP process utilizes a blankholder to control the flow of material into the forming cavity during the drawing stage and therefore requires the addition of an integrated cushion system in the bed of the press. HDMP dies are of interest in automotive applications because they maintain the low-investment attributes of SPF tooling while also significantly reducing the forming time as compared to conventional SPF. This work details the CAE based design of an HDMP die to form a one-piece aluminum door inner that can not be formed with conventionally forming processes. Critical aspects addressed in the development of the die include manufacturing targets, part design for manufacturing, and die design for operation at elevated temperature.

Full text
Abstract:
The identification of microplastics (MPs; 1 µm - 5 mm) and the inferred presence of nanoplastics (NPs; <1 µm) in a wide variety of marine animals, including many seafood species, has raised important questions about the presence, movement, and impacts of these particles in marine food webs. Understanding microplastic dynamics in marine food webs requires elucidation of the processes involved, including bioaccumulation, trophic transfer, and biomagnification. However, in the context of microplastics and nanoplastics these concepts are often misunderstood. In this chapter, we provide a critical review of the literature on the behavior of plastic particles in marine food webs. We find clear evidence of trophic transfer, equivocal evidence for bioaccumulation, and no evidence for biomagnification. We also identify a number of knowledge gaps that limit our ability to draw firm conclusions at this time. These supplemental documents are in support of an invited chapter to be published in this book: S.E. Shumway and J.E. Ward (Eds.) Plastics in the Sea: Occurrence and Impacts (Elsevier 2023).

Abstract:
Analysis of intersecting social inequalities is key to effective, inclusive interventions in crisis settings. Gender equality and social inclusion analytical frameworks provide key research questions and participatory methodologies which seek to understand: Who is excluded? How are they excluded? Why are they excluded? What can be done to address this and support greater inclusion? There is a focus on underlying power dynamics, drivers of marginalisation, and entry points for external support. This rapid review presents a summary of relevant analytical frameworks and good practice for analysing intersecting social inequalities in crisis settings. The focus is on how to undertake contextual analysis of the vulnerabilities and needs of people in crises that are shaped by overlapping and compounding social inequalities, arising from discrimination based on gender, age, disability, sexual orientation, gender identity and/or expression and sex characteristics, ethnicity and religion (among other identifiers). The review draws on and presents prior research that identified relevant analytical frameworks, learning and key resources on how to undertake this type of analysis, through a rapid literature search and input by key experts. It summarises a range of frameworks relevant for analysing intersecting social inequalities in crisis settings, developed for various development, humanitarian and peacebuilding objectives. It was harder to find published learning from undertaking this analysis that focuses specifically on crisis settings, but it was possible to draw findings from some individual case studies as well as relevant summaries of learning presented in the analytical frameworks and other guidance materials.

Abstract:
The purpose of this article is an analysis of opportunities and description of the experience of developing and implementing augmented reality technologies to support the teaching of chemistry in higher education institutions of Ukraine. The article is aimed at solving problems: generalization and analysis of the results of scientific research concerning the advantages of using the augmented reality in the teaching of chemistry, the characteristics of modern means of creating objects of augmented reality; discussion of practical achievements in the development and implementation of teaching materials on chemistry using the technologies of the augmented reality in the educational process. The object of research is augmented reality, and the subject - the use of augmented reality in the teaching of chemistry. As a result of the study, it was found that technologies of augmented reality have enormous potential for increasing the efficiency of independent work of students in the study of chemistry, providing distance and continuous education. Often, the technologies of the augmented reality in chemistry teaching are used for 3D visualization of the structure of atoms, molecules, crystalline lattices, etc., but this range can be expanded considerably when creating its own educational products with the use of AR-technologies. The study provides an opportunity to draw conclusions about the presence of technologies in the added reality of a significant number of benefits, in particular, accessibility through mobile devices; availability of free, accessible and easy-to-use software for creating augmented-reality objects and high efficiency in using them as a means of visibility. The development and implementation of teaching materials with the use of AR-technologies in chemistry teaching at the Kryvyi Rih State Pedagogical University has been started in the following areas: creation of a database of chemical dishes, creation of a virtual chemical laboratory for qualitative chemical analysis, creation of a set of methodical materials for the course “Physical and colloidal chemistry”.

Stelmakh, Marta. HISTORICAL CONTEXT IN THE COLLECTION OF ARTICLES BY TIMOTHY SNYDER «UKRAINIAN HISTORY, RUSSIAN POLITICS, EUROPEAN FUTURE». Ivan Franko National University of Lviv, March 2021. http://dx.doi.org/10.30970/vjo.2021.50.11098.

Full text
Abstract:
The article examines the problem of the image formation of Ukraine in the international arena in the historical journalism of Timothy Snyder. The subject of the research is the historical context in the journalistic collection «Ukrainian History, Russian Politics, European Future». It identifies the main considerations of the author on the past of Russian-Ukrainian relations and the need to develop historical consciousness in the fight against Russian manipulation. Methodology: the comparative, historical, system analysis and other methods are used in the process of scientific research. The results of the study were obtained by analysing the author’s journalistic works and by considering the main historical themes raised by Timothy Snyder. Main results: The historical context in Timothy Snyder’s journalism is often focused on the Holodomor and the events of World War II. After all, these events are connected with the beginning of the image formation of the Ukrainian people as supporters of Nazism by the Russian authorities and the devaluation of the Ukrainians’ contribution to the establishment of peace during the Second World War. It is determined that the non-reflective attitude to history, the inability to draw parallels between the events of the past and the future leads to an ineffective response to manipulation and propaganda, which can threaten world peace. Conclusions: the realization that Russian aggression against Ukraine has its own history is a necessary aspect in the elucidation of this issue. The Eurasian Union and cooperation with the European far-right are Russian propaganda tools that discredit the Ukrainian state in the world community. Publicist Timothy Snyder points out that Europe’s future interconnects with the past, so he emphasizes the need to study and rethink history, which today has become the object of propaganda and manipulation. Significance: The results of our study will help journalists who study the historical aspect of journalistic materials and research foreign materials on Ukrainian issues. In addition, our research is necessary for Ukraine, because Russia’s aggression continues, as well as the aggressor’s propaganda, which is based on the distortion and falsification of historical events.

Milek, Karen, and Richard Jones, eds. Science in Scottish Archaeology: ScARF Panel Report. Society of Antiquaries of Scotland, September 2012. http://dx.doi.org/10.9750/scarf.06.2012.193.

Full text
Abstract:
The main recommendations of the panel report can be summarised under four key headings:  High quality, high impact research: the importance of archaeological science is reflected in work that explores issues connected to important contemporary topics, including: the demography of, the nature of movement of, and contact between peoples; societal resilience; living on the Atlantic edge of Europe; and coping with environmental and climatic change. A series of large-scale and integrated archaeological science projects are required to stimulate research into these important topics. To engage fully with Science in Scottish Archaeology iv these questions data of sufficient richness is required that is accessible, both within Scotland and internationally. The RCAHMS’ database Canmore provides a model for digital dissemination that should be built on.  Integration: Archaeological science should be involved early in the process of archaeological investigation and as a matter of routine. Resultant data needs to be securely stored, made accessible and the research results widely disseminated. Sources of advice and its communication must be developed and promoted to support work in the commercial, academic, research, governmental and 3rd sectors.  Knowledge exchange and transfer: knowledge, data and skills need to be routinely transferred and embedded across the archaeological sector. This will enable the archaeological science community to better work together, establishing routes of communication and improving infrastructure. Improvements should be made to communication between different groups including peers, press and the wider public. Mechanisms exist to enable the wider community to engage with, and to feed into, the development of the archaeological and scientific database and to engage with current debates. Projects involving the wider community in data generation should be encouraged and opportunities for public engagement should be pursued through, for example, National Science Week and Scottish Archaeology Month.  Networks and forums: A network of specialists should be promoted to aid collaboration, provide access to the best advice, and raise awareness of current work. This would be complemented by creating a series inter-disciplinary working groups, to discuss and articulate archaeological science issues. An online service to match people (i.e. specialist or student) to material (whether e.g. environmental sample, artefactual assemblage, or skeletal assemblage) is also recommended. An annual meeting should also be held at which researchers would be able to promote current and future work, and draw attention to materials available for analysis, and to specialists/students looking to work on particular assemblages or projects. Such meetings could be rolled into a suitable public outreach event.

Abstract:
This report reviews research and findings on adolescents and reproductive health in Pakistan. The material is drawn from a range of national surveys and medical research, as well as information gathered by nongovernmental organizations. Although adolescents make up a quarter of the population of Pakistan, they are still a new subject for research. The characterization of adolescents for this review is individuals ages 10–19, whether or not they are married, sexually active, or parents. The discussion of the research material is based on the assumption that adolescence is a developmental phase, a transition from childhood to adulthood. Basic data on education, employment, and reproductive health among adolescents shows that they are not receiving adequate schooling and capability building to equip them for the future. Due to their relative youth, lack of decision-making power, and incomplete personal development, adolescents are ill equipped to handle the reproductive health burden they face. Policies and programs, as well as legal provisions, do not protect adolescents and need to be designed to meet the needs of adolescents without disrupting their development into adults.

Abstract:
Plastics as an environmental problem have been in the focus of science, politics and the public for a long time. Various sources and pathways have already been identified and a wide range of measures have been developed to reduce and, if possible, avoid inputs into the environment. Artificial grass pitches represent a special source of plastic inputs into the environment. Artificial grass with different infill materials has been widely used for some time now on surfaces for a wide range of sports, both amateur and professional. It is characterised by various advantages over natural grass. However, the use of artificial grass on sports surfaces also has its downsides, especially for the environment. On the one hand, the synthetic grass fibres themselves, which become detached through wear, are problematic. On the other hand, synthetic granulate is used as infill material on these pitches to reduce the risk of injury to players, to support the blades of artificial grass and to improve the playing characteristics of the field. However, this granulate can enter the environment in various ways - indirectly via drainage systems or directly. The following comments reflect research results from the InRePlast project. In the following chapter 2, the results of our own investigations on the topic are presented. In Chapter 3, these are compared to other publications and evaluated with regard to their significance. Chapter 4 is devoted to technical and organisational measures to reduce discharges as well as legal approaches to regulation. Finally, Chapter 5 draws a conclusion. Among other things, the study concludes that artificial grass pitches are less relevant as a specific source of plastic inputs than previously discussed. It should also be noted that the input into drainage systems via the collection of dirty water has a significantly higher relevance than the input via the collection of precipitation at the edge of the pitch and that measures should therefore focus on the carry-over on players' clothing and shoes.

Revill, James, and Kai Ilchmann. Assessing the SecBio Platform Proposal for the Biological Weapons Convention. UNIDIR, December 2022. http://dx.doi.org/10.37559/wmd/22/bwc/04.

Full text
Abstract:
Biosecurity and biosafety are important aspects of the life sciences and they have been discussed in the Biological Weapons Convention (BWC) on several occasions. Moreover, several initiatives are underway to advance biosecurity and safety. However, these initiatives are often context specific and the effective implementation of biosecurity and biosafety measures around the globe remains inadequate. To address this gap, in 2022, France, Senegal and Togo submitted a revised proposal to the BWC for the “establishment of an international platform dedicated to biosecurity and biosafety: SecBio”. The proposal includes three pillars: a searchable repository for biosafety- and biosecurity-related materials; a learning module; and a forum for expert networking to exchange information, data and best practices. To this end, this report draws lessons from past initiatives to develop repositories, learning modules and expert forums in order to inform the development of the SecBio platform (and any such similar initiatives). The report begins with an overview of the importance of biosafety and biosecurity in the context of the BWC. It then proceeds to look at each of the platform pillars in turn, drawing from past experiences to identify lessons and develop options for state parties to consider.
