Abstract3D printing or additive manufacturing (AM) is considered as a flexible manufacturing method with the potential for substantial innovations in fabricating geometrically complicated structured polymers, metals, and ceramics parts. Among them, polymeric composites show versatility for applications in various fields, such as constructions, microelectronics and biomedical. However, the poor resistance of these materials against fire must be considered due to their direct relation to human life conservation and safety. In this article, the recent advances in the fire behavior of 3D-printed polymeric composites are reviewed. The article describes the recently developed methods for improving the flame retardancy of 3D-printed polymeric composites. Consequently, the improvements in the fire behavior of 3D-printed polymeric materials through the change in formulation of the composites are discussed. The article is novel in the sense that it is one of the first studies to provide an overview regarding the flammability characteristics of 3D-printed polymeric materials, which will further incite research interests to render AM-based materials fire-resistant.

Abstract The textile industry uses many raw materials (natural and synthetic dyes and fibers) and different dyeing techniques that can be considered important pollutants with a negative impact on the environment (toxic working conditions, discharged wastewater, and contamination). Although synthetic dyes are intensively used, offer a wide range of colors and hues and properties of adhesion, longevity, and resistance to sunshine and chemical processes, and are cost-effective, they have begun to be restricted by many textile producers because they are nonbiodegradable and have toxic, carcinogenic, and mutagenic effects that generate some imbalances in plant, animal, and human life. Natural dyes of plant and animal origin exhibit very good tolerance to washing, rubbing, and light and are biodegradable and nontoxic; these properties have led to a call for the renewed use of these dyes. Modern analytical techniques (solid-phase extraction, spectrophotometry, HPLC, HPTLC, capillary electrophoresis) with different spectroscopy (UV-Vis, diode-array detection, pulsed amperometric detection) and/or MS/tandem mass spectrometry detectors have an important role in the textile industry in obtaining essential information about dyeing techniques, material origin, historical trade routes of ancient textiles, and environmental pollution. For this purpose, isolation, separation, and quantification methods of natural and synthetic textile dyes from various matrices (ancient and modern fabrics, water, biota, etc.) are presented.

The smart textile industry has become increasingly interested in textile products with electronic functions. In these smart textile products, sensing and data communication are conducted through conductive circuits by conductive threads. In embroidery technology that uses conductive threads as the material for the conductive line as a circuit, their resistance is an important factor when designing a product. The main purpose of this study was to derive an equivalent circuit model and a calculation equation for the consumption of conductive threads according to the embroidery design parameters. The effects of the embroidery design parameters on the appearance and electrical characteristics of the conductive line were also analyzed. The appearance and electrical characteristics of the embroidered conductive line were different when the embroidery design parameters were not the same. The calculation equation for the consumption of conductive threads could establish a quantitative system that could indicate the line resistance of an embroidered conductive line using the embroidery design parameters and the given thread resistance.

Fire Patterns

Changes in climate, land use, and land management impact the occurrence and severity of wildland fires in many parts of the world. This is particularly evident in Europe, where ongoing changes in land use have strongly modified fire patterns over the last decades. Although satellite data by the European Forest Fire Information System provide large-scale wildland fire statistics across European countries, there is still a crucial need to collect and summarize in-depth local analysis and understanding of the wildland fire condition and associated challenges across Europe. This article aims to provide a general overview of the current wildland fire patterns and challenges as perceived by national representatives, supplemented by national fire statistics (2009–2018) across Europe. For each of the 31 countries included, we present a perspective authored by scientists or practitioners from each respective country, representing a wide range of disciplines and cultural backgrounds. The authors were selected from members of the COST Action “Fire and the Earth System: Science & Society” funded by the European Commission with the aim to share knowledge and improve communication about wildland fire. Where relevant, a brief overview of key studies, particular wildland fire challenges a country is facing, and an overview of notable recent fire events are also presented. Key perceived challenges included (1) the lack of consistent and detailed records for wildland fire events, within and across countries, (2) an increase in wildland fires that pose a risk to properties and human life due to high population densities and sprawl into forested regions, and (3) the view that, irrespective of changes in management, climate change is likely to increase the frequency and impact of wildland fires in the coming decades. Addressing challenge (1) will not only be valuable in advancing national and pan-European wildland fire management strategies, but also in evaluating perceptions (2) and (3) against more robust quantitative evidence.

ABSTRACTLayered Manufacturing (LM) refers to computer-aided manufacturing processes in which parts are made in sequential layers relatively quickly. Parts that are produced by LM can be formed from a wide range of materials such as photosensitive polymers, metals and ceramics in sizes from a centimeter to a few meters with sub-millimeter feature resolutions. LM has found use in diverse areas including biomedical engineering, pharmaceuticals, aerospace, defense, electronics and design engineering. The promise of LM is the capability to make customized complex-shaped functional parts without specialized tooling and without assembly. LM is still a few years away from fully realizing its promise but its potential for manufacturing remains high. A few of the fundamental challenges in materials processing confronting the community are improving the quality of the surface finish, eliminating residual stress, controlling local composition and microstructure, achieving fine feature size and dimensional tolerance and accelerating processing speed. Until these challenges are met, the applicability of LM and its commercialization will be restricted. Sustained scientific activity in LM has advanced over the past decade into many different areas of manufacturing and has enabled exploration of novel processes and development of hybrid processes. The research community of today has the opportunity to shape the future direction of science research to realize the full potential of LM.

The chapter surveys early Greek medicine, primarily the works attributed to Hippocrates, but also evidence for other medical writing, such as that in the Anonymus Londinensis papyrus, and in the fragments of the pre-Socratics. It is noted that the fragments of Alcmaeon indicate experience in dissection of animals, that Diogenes of Apollonia gives a detailed account of the vascular system, and that Plato has an extensive biomedical section in Timaeus. In general, early medical writers show concern with the relation of microcosm to macrocosm and of human life to the universe; also, with opposing principles (hot and cold, wet and dry, thick and thin, rare and dense) such that health is commonly seen in terms of bodily balance and avoidance of excess. The seventy or so works of the Hippocratic corpus cover a wide range of subjects, notably prognostic signs, surgery, gynecology, case histories and aphoristics lore.
