Full text
Abstract:
AbstractApproaches for the collection and analysis of plastic debris in environmental matrices are rapidly evolving. Such plastics span a continuum of sizes, encompassing large (macro-), medium (micro-, typically defined as particles between 1 μm and 5 mm), and smaller (nano-) plastics. All are of environmental relevance. Particle sizes are dynamic. Large plastics may fragment over time, while smaller particles may agglomerate in the field. The diverse morphologies (fragment, fiber, sphere) and chemical compositions of microplastics further complicate their characterization. Fibers are of growing interest and present particular analytical challenges due to their narrow profiles. Compositional classes of emerging concern include tire wear, paint chips, semisynthetics (e.g., rayon), and bioplastics. Plastics commonly contain chemical additives and fillers, which may alter their toxicological potency, behavior (e.g., buoyancy), or detector response (e.g., yield fluorescence) during analysis. Field sampling methods often focus on &gt;20 μm and even &gt;300 μm sized particles and will thus not capture smaller microplastics (which may be most abundant and bioavailable). Analysis of a limited subgroup (selected polymer types, particle sizes, or shapes) of microplastics, while often operationally necessary, can result in an underestimation of actual sample content. These shortcomings complicate calls for toxicological studies of microplastics to be based on “environmentally relevant concentrations.” Sample matrices of interest include water (including wastewater, ice, snow), sediment (soil, dust, wastewater sludge), air, and biota. Properties of the environment, and of the particles themselves, may concentrate plastic debris in select zones (e.g., gyres, shorelines, polar ice, wastewater sludge). Sampling designs should consider such patchy distributions. Episodic releases due to weather and anthropogenic discharges should also be considered. While water grab samples and sieving are commonplace, novel techniques for microplastic isolation, such as continuous flow centrifugation, show promise. The abundance of nonplastic particulates (e.g., clay, detritus, biological material) in samples interferes with microplastic detection and characterization. Their removal is typically accomplished using a combination of gravity separation and oxidative digestion (including strong bases, peroxide, enzymes); unfortunately, aggressive treatments may damage more labile plastics. Microscope-based infrared or Raman detection is often applied to provide polymer chemistry and morphological data for individual microplastic particles. However, the sheer number of particles in many samples presents logistical hurdles. In response, instruments have been developed that employ detector arrays and rapid scanning lasers. The addition of dyes to stain particulates may facilitate spectroscopic detection of some polymer types. Most researchers provide microplastic data in the form of the abundances of polymer types within particle size, polymer, and morphology classes. Polymer mass data in samples remain rare but are essential to elucidating fate. Rather than characterizing individual particles in samples, solvent extraction (following initial sample prep, such as sediment size class sorting), combined with techniques such as thermoanalysis (e.g., pyrolysis), has been used to generate microplastic mass data. However, this may obviate the acquisition of individual particle morphology and compositional information. Alternatively, some techniques (e.g., electron and atomic force microscopy and matrix-assisted laser desorption mass spectrometry) are adept at providing highly detailed data on the size, morphology, composition, and surface chemistry of select particles. Ultimately, the analyst must select the approach best suited for their study goals. Robust quality control elements are also critical to evaluate the accuracy and precision of the sampling and analysis techniques. Further, improved efforts are required to assess and control possible sample contamination due to the ubiquitous distribution of microplastics, especially in indoor environments where samples are processed.

This article deals with morphological non-active verbal voice, which characterises reflexive, middle and passive structures in Standard Albanian and Arbëresh dialects. The data, compared to those of Italian, show that the three different strategies for the realisation of Standard Albanian and Arbëresh non-active morphology interact with the categories of mood, tense and aspect. In particular, these morphological strategies determine a perfective/ imperfective split as well as a series of restrictions which convey different interpretations associated with a stative or eventive interpretation. Particular attention is paid to the possible influence of Italian structures on the Italo-Albanian varieties in the domain of non-active voice.

Abstract:
Abstract“Sustainable cities” as a singular concept may very well be a utopian vision impossible to realise in a broader sense. In this chapter, we review the literature on urban sustainability highlighting the complexities and trade-offs between and within the 3 Es—ecology, economy and equality. In particular, we focus here on the intra-urban dimensions of density, mobility, the built environment and housing, lifestyle trends and gentrification along with social sustainability issues of crime, homelessness and community. While gains from increased size and density can be had, there are also many outcomes that depend on urban morphology and the consequences of spatial sorting. Positive outcomes generated by density and efficiency may be offset by, for instance, less sustainable construction materials or increased income inequality. In particular, rebound effects are often overlooked. Hence, it often becomes an empirical issue whether the potential for sustainability gains materialise. Furthermore, as assessed from a more holistic 3 Es’ view, where social sustainability is as important as environmental sustainability, the potential of a “sustainable city” may be a victim of trade-offs that are difficult to resolve.

Abstract:
AbstractThe design of medical devices is challenging, due to strict geometry specifications and criteria belonging to several disciplines. The aim of this paper is to provide a design methodology which seems to lack in the literature of design of biomedical devices. In particular, the case study proposed in this paper concerns with the design of Bone-Biopsy (BB) needle devices. Following the design process of Pahl and Beitz, a functional analysis is carried out, to point out the interfaces between parts of existing BB needles. A morphology matrix is used to generate alternatives for the cannula holder, the core part of the product. Generated alternatives have been ranked and scored by means of the Pugh’s Controlled Convergence method according to the decision makers' opinions. In this work, the design peculiarities related to the BB needles which have been pointed out could be extended for guiding the design of other biomedical devices.

Abstract:
This chapter reviews how morphological randomness is dealt with at different size levels, beginning with eukaryotic microorganisms, where we see the greatest amount of morphological randomness in both aquatic and terrestrial forms. It suggests that microorganisms might in some circumstances have neutral morphologies. This means that there are significant differences between individual morphologies, but natural selection is blind to them. It proposes candidates for this unconventional condition for both aquatic and terrestrial forms. In particular, it considers eukaryotic microorganisms, and not bacteria and archaea. The concern here is with morphology and the degree to which it is adaptive, and bacteria and archaea have very limited morphologies; their variation exists mostly in the form of multitudinous biochemical differences.

Zinc oxide (ZnO) is a key material for this purpose due to the variety of facile methods that exist to produced ZnO nanostructures with tailored sizes, morphologies, and optical and electrical properties. In particular, ZnO nanostructures with a porous structure are advantageous over other morphologies for many applications because of their high specific surface area. In this chapter, a literature review on the latest progress regarding the synthesis and applications of ZnO with a porous morphology will be provided, with special focus on the synthesis by microwave hydrothermal method of these nanomaterials and their potential for application in energy harvesting devices. Nanogenerators of a composite made by polydimethylsiloxane (PDMS) and porous ZnO nanostructures were explored and optimized, with an output voltage of (4.5 ± 0.3) V being achieved for the best conditions. The daily life applicability of these devices was demonstrated by lighting up a commercial LED, by manually stimulating the nanogenerator directly connected to the LED.

Abstract:
Abstract Morphology is the study of the internal structure of words. I approach the topic with a couple of very straightforward cases. The first example concerns a word whose analysis into its component morphemes is beyond dispute; the second example concerns a word which is clearly not analysable into component morphemes. In spite of their seeming simplicity, the examples will allow us to apply and refine some of the theoretical notions introduced so far, concerning, in particular, the function of schemas in linguistic analysis. Further aspects of word structure are addressed in Chapters 15 and 16.

Abstract:
Beate I. Allert investigates Fichte’s Science of Knowing against the backdrop of Goethe’s Morphology, and shows competing models of assembly and disassembly in eighteenth-century German science, literature, philosophy, and art. Goethe adopts elements of Leibniz’s Monadology, expresses his notion of the particular and the universal through reference to the organizing principle, his “Urpflanze,” and depicts fluid connections between humans, animals, and plants in ways that ultimately situate the human in the center of the universe. On the political level, he judges revolution to be unnecessary; thus, Goethe’s model of assembly sketches a prototype that posits a botanical-anthropocentric ideal as the foundation of nature. Fichte emphasizes an image of nature in which one finds a world of disjointed objects and disordered elements that make revolution necessary and immanent. Other romantics attempt to navigate between these two juxtaposed models of assembly (Morphologie) and disassembly (Wissenschaftslehre).

Abstract:
Improved knowledge of large outdoor fire particulate emissions is needed at the laboratory-scale. Here, samples of oriented strand board (OSB), a common human-made fuel abundant cities, were ignited using a radiant heater coupled to a spark igniter. Particulate samples were taken to begin to look at the morphology of the generated particulates. Using a simple experimental setup affords the capability to investigate particulates produced from smoldering combustion as well as those collected from flaming combustion. As the nature of particulate samples were expected to be sensitive to the voltage of the electron beam for smoldering combustion in particular, scanning electron microscopy (SEM) was used as first step to investigate the morphology. Transmission electron microscopy (TEM) operates at higher acceleration voltages and this is expected to influence the samples. As a direct comparison to the results from the engineered cellulosic based material experiments, branches from conifer trees, a natural vegetative fuel, were also exposed to a radiant heater and particulate samples were collected using similar experimental protocols. morphology of the generated particulates is greatly influenced by the state of combustion for both the engineered cellulosic based material (OSB) as well as those collected for natural vegetation. Results of this study will be presented

Abstract:
Atherosclerotic plaque rupture has been extensively associated with acute myocardial infarctions, the leading cause of death in developed countries. When a plaque ruptures in the coronary arteries, it often leads to a clot formation that restricts the flow of blood downstream of the coronaries causing damage to the myocardial tissue. Hemodynamic factors combined with certain plaque morphologies and material properties play an important role in the mechanical failure of the plaque [1]. It is essential for clinicians to understand the vulnerability of plaques and the particular physiological con

Abstract The effectiveness of metallic foams in forced convection heat removal is studied. The metallic foam showed an improved heat removal rate with a moderate increase in the pressure drop. The hydraulic and thermal characteristics are analyzed experimentally. The measurements are used in conjunction with a model based on a bank of cylinders in cross-flow to understand the effect of various foam morphologies. The model prediction is extrapolated to examine the trade-off between heat removal and pressure drop. For a particular working fluid, the model provides two sets of design parameters;

Since the early 1970s wear particles have been used as indicators of the health status of industrial machinery. Their quantity, size and morphology was utilized in machine condition monitoring to diagnose and predict the likelihood or the cause of machine failure. In particular, the wear particle morphology was found useful as it contains the vast wealth of information about the wear processes involved in particle formation, and the wear severity. However, the application of wear particle morphology analysis in machine condition monitoring has limitations. This is due to the fact that the proc
