description: Polymer assisted spherical FeNi nanoparticles were prepared via wet chemical method using hydrazine as a reducing agent and polymers (PVP and PEG) as reducing and stabilizing agent. Structural studies performed using XRD and TEM shows uniform dispersion of fine FeNi nanocrystallites in nanocomposite particles. The size and thermal stability of FeNi nanoparticles prepared under same reaction condition was found to be dependent on the type and the molecular weight of the polymer used. However, the magnetic properties of nanocomposite particles were not influenced by the polymers. The study highlights subtle differences in using polymers during the synthesis of alloyed nanocomposite particles.

description: In this paper, we use a traveling wave reduction or a so-called spatial approximation to comprehensively investigate periodic and solitary wave solutions of the modified Benjamin, Bona & Mahony equation (BBM) to include both dissipative and dispersive effects of viscous boundary layers. Under certain circumstances that depend on the traveling wave velocity, classes of periodic and solitary wave like solutions are obtained in terms of Jacobi elliptic functions. An ad-hoc theory based on the dissipative term is presented, in which we have found a set of solutions in terms of an implicit function. Using dynamical systems theory we prove that the solutions of \eqref{BBMv} experience a transcritical bifurcation for a certain velocity of the traveling wave. Finally, we present qualitative numerical results.

description: Advances in Artificial Intelligence (AI) research and development have seen AI applied in various high-stakes domains such as healthcare and welfare. Furthermore, portrayals of AI are often characterised by narratives of perpetual progress and sleek optimisation, obscuring the intricate interactions of materiality and socio-political decision-making inherently embedded within wider systems of design and development. The resulting ethical and social concerns have prompted proposal of numerous frameworks, tools and guidelines for the ethical design and development of AI. However, translating these proposals into practice has proven challenging, and there is a paucity of research into the practical contexts shaping the ethico-onto-epistemology of AI practice. In this thesis I illustrate these contexts via the accounts of 24 AI practitioners, complemented by ethnographic observations from an industry research lab, examining the values which motivate practitioners, the constraints which shape their practice, and their approaches to ethics. Weaving through these discussions of practice, values, and the nature of responsibility, I examine how ambiguities pervade practice and shape the realities of ethical reflection and engagement at all stages of development. My findings uncover practitioner motivations linked with interconnected intellectual and moral values, how these related to intellectual conduct and culture within the field, and how practitioner heuristics for ethical decision-making are often relational and character-based in nature. This realization of values in practice is tempered by numerous constraints including hardware limitations, epistemic cultures, and ethical knowledge. Drawing upon the Ethics of Ambiguity, I discuss how the uncertainty, ambiguity and unequal access to resources shaping AI practice necessitate a process-focused ethics which pivots away from solutions, towards critical contextual reflexivity and awareness of how contexts impact realisation of values. To this end, I demonstrate how The Ethics of Ambiguity can offer a path forward for ethical AI practice. This vision of AI practice embraces ambiguities rather than attempting to segment and sideline them, focusing on how practitioner decisions (and their eventual outputs) impact others’ freedoms while acknowledging the multiplicity of values across socio- and geo-political contexts.

description: In fact, information systems are the foundation of new productivity sources, medical organizational forms, and erection of a global economy. IoT based healthcare systems play a significant role in ICT and have contribution in growth of medical information systems, which are underpinning of recent medical and economic development strategies. However, to take advantages of IoT, it is essential that medical enterprises and community should trust the IoT systems in terms of performance, security, privacy, reliability and return-on-investment, which are open challenges of current IoT systems. For heightening of healthcare system; tracking, tracing and monitoring of patients and medical objects are more essential. But due to the inadequate healthcare situation, medical environment, medical technologies and the unique requirements of some healthcare applications, the obtainable tools cannot meet them accurately. The tracking, tracing and monitoring of patients and healthcare actors activities in healthcare system are challenging research directions for IoT researchers. State-of-the-art IoT based healthcare system should be developed which ensure the safety of patients and other healthcare activities. With this manuscript, we elaborate the essential role of IoT in healthcare systems; immense prospects of Internet of things in healthcare systems; extensive aspect of the use of IoT is dissimilar among different healthcare components and finally the participation of IoT between the useful research and present realistic applications. IoT and few other modern technologies are still in underpinning stage; mainly in the healthcare system.

description: It is a matter of record that while music in the West steadily incorporated polyphony from the ninth century onwards, sacred music in Russia remained largely monophonic until around mid–17th century, when Western–style polyphony (partesny) suddenly appeared and was incorporated. However, the extant literature does not provide any fully satisfactory explanation for the success of this sudden incursion of polyphony, after almost seven centuries of concerted monophony. Accordingly, in this thesis, I examined the period from 1650–1750 in detail, to clarify the factors either promoting, or inhibiting, the abrupt appearance of polyphony. I identified several powerful pre–existing inhibitors, which I conclude had collectively barred polyphony up to mid–17th century. These included religious opposition, geographical isolation, a lack of training facilities and of singers capable of part singing, and musical roadblocks in the traditional Russia monophonic canon. I proposed that the appearance of partesny was directly and temporally related to the softening and eventual disappearance of these inhibitors. In addition, numerous promoters of polyphony long operative in the West, that had previously been largely absent in Russia, emerged gradually as inhibitors waned. I conclude that the array of inhibitors identified played a primary role in successfully holding polyphony at bay until mid–17th century, with an additional lack of promoters playing a secondary role. I further suggest that while the secular music that developed subsequently in the 18th and subsequent centuries could have incorporated polyphony independently of sacred music at several different historical time points, ingress of polyphony into Russian liturgical music may only have been practically possible in the period from 1650–1750. Failing that, it is plausible that Russia’s sacred music could have remained largely monophonic to the present day, as is the case for Greek sacred music.

description: Intensive potato production may reduce the soil organic matter content (SOM), which may impact several soil functions and increase the incidence of potato diseases. We examined if cover crop and addition of organic materials may counteract these effects. Organic materials were one application of biochar mixed with liquid digestate (BLD); solid digestate (SD); or farmyard manure (FYM); with or without winter rye as cover crop, in a field with regular potato growing. Organic amendment increased SOM, especially for FYM and BLD, while cover crop did not affect SOM. Yet, cover crop increased tuber yields in the second year, and reduced the severity of potato diseases by 10% in post-harvest potatoes in both years. In the second year, the number of marketable potatoes after storage increased by 37% with cover crop. Organic amendments did not affect potato yield or quality, but the proportion of marketable potatoes tended to be higher in the amended soil. By lab incubation, BLD showed the largest potential for SOM storage, up to 32 years, followed by FYM and SD. Cover crops and organic amendments is recommended in potato production, especially for early potatoes where there is sufficient time after harvest to establish a good cover crop.

description: Ferromagnetic shape-memory CoNiGa alloys have attracted much scientific interest due to their potential alternative use as high-temperature shape-memory alloys, bearing a high prospect for actuation and damping applications at elevated temperatures. Yet, polycrystalline CoNiGa, due to strong orientation dependence of transformation strains, suffers from intergranular fracture. Here, two multi-grain CoNiGa samples were prepared by a novel hot extrusion process that can promote favourable grain-boundary orientation distribution and improve the material's mechanical behaviour. The samples were investigated by multiple methods and their microstructural, magnetic, and mechanical properties are reported. It is found that a post-extrusion solutionising heat treatment leads to the formation of a two-phase oligocrystalline homogeneous microstructure consisting of an austenitic parent B2 phase and γ-CoNiGa precipitates. Reconstruction of the full 3D grain morphology revealed large, nearly spherical grains with no low-angle grain boundaries throughout the entire sample volume. The presence of γ precipitation affects the transformation behaviour of the samples, by lowering the martensitic transformation temperature, while, in conjunction with the oligocrystalline microstructure, it improves the ductility. Controlling the composition of the B2 matrix, as well as the phase fraction of the γ phase, is thus crucial for the optimal behaviour of the alloys.

description: Co-application of fertilisers and biofertilisers increases solubility and concentration of nutrient elements in the soil. However, information on the effect of P fertiliser and rhizobium inoculation on the concentration of mineral elements in the rhizosphere of field-grown chickpea in contrasting soil types is lacking. We assessed the effect of phosphorus fertiliser, rhizobium inoculation, and rhizobium inoculation plus P fertilizer on the concentration of nutrients in the rhizosphere of 2 chickpea genotypes (ACC#1 & ACC#5) at clay and sandy soil sites in two consecutive years. ACC#5 accumulated higher amounts of rhizospheric nutrients than ACC#1 in both soil types despite the variable response to fertiliser treatment. Rhizobium inoculation plus P fertiliser resulted in higher accumulations of rhizosphere N (7-219%), P (20-348%), K (9-365%), Ca (2-155%) and Zn (15-259%) compared to the other fertiliser treatments suggesting an additive effect of P fertiliser and rhizobium inoculation. Moreover, the effect of fertiliser treatments was more pronounced in the clay than the sandy soil. Our investigation is the first to document the effects of fertiliser treatment, genotype, and soil type on the accumulation of rhizosphere nutrients in field-grown chickpea. However, we propose further studies, incorporating more cultivars and environments, before making practical recommendations.

description: Plasmons produce large confinement and enhancement of light that enable applications as varied as cancer therapy and catalysis. Adding to these appealing properties, graphene has emerged as a robust, electrically tunable material exhibiting plasmons that strongly depend on the density of doping charges. Here we show that adding a single electron to a graphene nanoisland consisting of hundreds or thousands of atoms switches on infrared plasmons that were previously absent from the uncharged structure. Remarkably, the addition of each further electron produces a dramatic frequency shift. Plasmons in these islands are shown to be tunable down to near infrared wavelengths. These phenomena are highly sensitive to carbon edges. Specifically, armchair nanotriangles display sharp plasmons that are associated with intense near-field enhancement, as well as absorption cross-sections exceeding the geometrical area occupied by the graphene. In contrast, zigzag triangles do not support these plasmons. Our conclusions rely on realistic quantum-mechanical calculations, which are in ostensible disagreement with classical electromagnetic simulations, thus revealing the quantum nature of the plasmons. This study shows a high sensitivity of graphene nanoislands to elementary charges, therefore emphasizing their great potential for novel nano-optoelectronics applications.

description: The exposure to heat is currently seen as the most important direct impact of climate change on human health (Menne 2011: 6f). In areas with high levels of sealing and low aeration, the overheating in cities leads to urban heat islands. This results in an acute need for action for urban and environmental planning to optimally exploit the potential of local measures to mitigate this stress situation for urban residents and to be able to localize the adaptation measures to the changing climate. Against this background, planning action is crucial to the reduction of vulnerability as well as the targeted establishment of adaptation capacities against the effects of climate change (BMVBS 2010: 10). This master-thesis aim to use a GIS-based analysis to accurately identify the vulnerabilities of the city of Hanover against heat (depending on the different adaptive capacities of the room). The work shows that against the background of increasing climate change, the determination of the vulnerability of urban areas plays a central role in maintaining healthy living quality. Furthermore, this work has shown that vulnerability analysis is a central starting point when it comes to identifying vulnerable uses of space against the effects of climate change and making them more adaptable through planning measures.

description: Over the last 40 years, there has been an increasing amount of world interest on urban climatic map (UCMap) Studies. Up to now, there are over 15 countries around the world processing their own Climatic Maps, developing urban climatic guidelines and implementing mitigation measures for local planning practices. Facing the global issue of climate change, it is also necessary to factor the climatic consolidations holistically and strategically into the planning process. In the literature, the latest concepts are mentioned. Key methodologies, selected parameters, structure and making procedures, mitigation countermeasures and climatic recommendations of urban climatic map studies ware described. More than 30 relevant studies around the world are cited, and both significant developments and remaining problems are discussed. The review noted that the thermal environment and the air ventilation condition within the urban canopy layer play the most important role in the analytical aspects and climatic-environmental evaluation. It is also noted that possible mitigation measures and planned action can include decreasing anthropogenic heat release, improving air ventilation at pedestrian level, providing more shaded areas, increasing greenery, creating air paths, and controlling building construction. Future research should be focused on the spatial analysis of human thermal comfort in urban outdoor areas and climate change impacts and adaptation. It is also important to share the learned lessons and experiences with planners and policymakers in the rapidly expanding cities of the developing countries and regions.

description: The large-scale import of soybean products into the EU decreases the self-sufficiency of livestock production. The fractionation of grassland forage crops presents an opportunity to locally produce protein-rich feed for monogastrics. Two promising fractionation methods, twin-screw press juicing and leaf stripping, were evaluated in parallel in field experiments established in Norway and Sweden to compare the nutrient composition and yield of the resulting biorefined and residual fractions. The clearest delineation between the methods was in the ash-free neutral detergent fibre (aNDFom) concentration, with juicing producing a biorefined fraction with a lower aNDFom than leaf stripping. Variability in the allocation of crude protein (CP) and biomass to the biorefined fractions occurred in both methods between cuts and locations and is likely due to differing stand characteristics and inconsistency in machine functionality. Additional work is needed to understand how characteristics such as stand density, botanical composition, and plant phenological stage impact each fractionation method’s ability to allocate protein, fibre, and biomass into the resulting fractions. Future studies should focus particularly on determining standardised settings for leaf stripping machinery based on a range of stand characteristics to ensure consistency in the yield and nutrient composition of the resulting fractions.

Recently released data for proton and deuteron targets at HERMES and COMPASS permit a flavor separation of valence transversities. The present extraction is performed in the framework of collinear factorization, where dihadron fragmentation functions are involved. The latter are taken from a previous analysis of electron-positron annihilation measurements.

description: In this paper we study how to accelerate the convergence of the ratios (x_n) of generalized Fibonacci sequences. In particular, we provide recurrent formulas in order to generate subsequences (x_{g_n}) for every linear recurrent sequence (g_n) of order 2. Using these formulas we prove that some approximation methods, as secant, Newton, Halley and Householder methods, can generate subsequences of (x_n). Moreover, interesting properties on Fibonacci numbers arise as an application. Finally, we apply all the results to the convergents of a particular continued fraction which represents quadratic irrationalities.

description: Let $I$ be an infinite set, $\{G_i:i\in I\}$ be a family of (topological) groups and $G=\prod_{i\in I} G_i$ be its direct product. For $J\subseteq I$, $p_{J}: G\to \prod_{j\in J} G_j$ denotes the projection. We say that a subgroup $H$ of $G$ is: (i) \emph{uniformly controllable} in $G$ provided that for every finite set $J\subseteq I$ there exists a finite set $K\subseteq I$ such that $p_{J}(H)=p_{J}(H\cap\bigoplus_{i\in K} G_i)$; (ii) \emph{controllable} in $G$ provided that $p_{J}(H)=p_{J}(H\cap\bigoplus_{i\in I} G_i)$ for every finite set $J\subseteq I$; (iii) \emph{weakly controllable} in $G$ if $H\cap \bigoplus_{i\in I} G_i$ is dense in $H$, when $G$ is equipped with the Tychonoff product topology. One easily proves that (i)$\to$(ii)$\to$(iii). We thoroughly investigate the question as to when these two arrows can be reversed. We prove that the first arrow can be reversed when $H$ is compact, but the second arrow cannot be reversed even when $H$ is compact. Both arrows can be reversed if all groups $G_i$ are finite. When $G_i=A$ for all $i\in I$, where $A$ is an abelian group, we show that the first arrow can be reversed for {\em all} subgroups $H$ of $G$ if and only if $A$ is finitely generated. Connections with coding theory are highlighted.

description: We report a novel soft x-ray nanodiffraction study of antiferromagnetic domains in the strongly correlated bylayer manganite La$_{0.96}$Sr$_{2.04}$Mn$_{2}$O$_{7}$. We find that the antiferromagnetic domains are quenched, forming a unique domain pattern with each domain having an intrinsic memory of its spin direction, and with associated domain walls running along crystallographic directions. This can be explained by the presence of crystallographic or magnetic imperfections locked in during the crystal growth process which pin the antiferromagnetic domains. The antiferromagnetic domain pattern shows two distinct types of domain. We observe, in one type only, a periodic ripple in the manganese spin direction with a period of approximately 4 \micro\meter. We propose that the loss of inversion symmetry within a bilayer is responsible for this ripple structure through a Dzyaloshinskii-Moriya-type interaction.

description: Изучение новгородской архитектуры XII в. является актуальной темой для понимания стилистических черт русского зодчества в целом. Памятников XII в. в России сохранилось очень мало. А памятников с хорошей сохранностью монументальной живописи – единицы. Одним из таких памятников является церковь Благовещения в Аркажах. Обращение к исследованию данного памятника позволяет более глубоко изучить древнерусскую
архитектуру, составить наиболее объективное представление о живописном языке произведений того времени.

description: During metal cutting, high temperatures of several hundred-degree Celsius occur locally at the cutting edge, which greatly impacts tool wear and life. Not only the cutting parameters, but also the tool material’s properties influence the arising cutting temperature which in turn alters the mechanical properties of the tool. In this study, the hardness and thermal conductivity of cemented tungsten carbides were investigated in the range between room temperature and 1000 °C. The occurring temperatures close to the cutting edge were measured with two color pyrometry. The interactions between cemented carbide tool properties and cutting process parameters, including cutting edge rounding, are discussed. The results show that cemented carbides with higher thermal conductivities lead to lower temperatures during cutting. As a result, the effective hardness at the cutting edge can be strongly influenced by the thermal conductivity. The differences in hardness measured at room temperature can be equalized or evened out depending on the combination of hardness and thermal conductivity. This in turn has a direct influence on tool wear. Wear is also influenced by the softening of the workpiece, so that higher cutting temperatures can lead to less wear despite the same effective hardness.
