description: We propose a surrogate model for two-scale computational homogenization of elastostatics at finite strains. The macroscopic constitutive law is made numerically available via an explicit formulation of the associated macroenergy density. This energy density is constructed by using a neural network architecture that mimics a high-dimensional model representation. The database for training this network is assembled through solving a set of microscopic boundary value problems with the prescribed macroscopic deformation gradients (input data) and subsequently retrieving the corresponding averaged energies (output data). Therefore, the two-scale computational procedure for nonlinear elasticity can be broken down into two solvers for microscopic and macroscopic equilibrium equations that work separately in two stages, called the offline and online stages. The finite element method is employed to solve the equilibrium equation at the macroscale. As for microscopic problems, an FFT-based collocation method is applied in tandem with the Newton-Raphson iteration and the conjugate-gradient method. Particularly, we solve the microscopic equilibrium equation in the Lippmann-Schwinger form without resorting to the reference medium. In this manner, the fixed-point iteration that might require quite strict numerical stability conditions in the nonlinear regime is avoided. In addition, we derive the projection operator used in the FFT-based method for homogenization of elasticity at finite strain.

description: This paper is devoted to the experimental quantitative characterization of the shape and orientation distribution of ice particles in clouds. The characterization is based on measured and modeled elevation dependencies of the polarimetric parameters differential reflectivity and correlation coefficient. The polarimetric data are obtained using a newly developed 35 GHz cloud radar MIRA-35 with hybrid polarimetric configuration and scanning capabilities. The full procedure chain of the technical implementation and the realization of the setup of the hybrid-mode cloud radar for the shape determination are presented. This includes the description of phase adjustments in the transmitting paths, the introduction of the general data processing scheme, correction of the data for the differences of amplifications and electrical path lengths in the transmitting and receiving channels, the rotation of the polarization basis by 45°, the correction of antenna effects on polarimetric measurements, the determination of spectral polarimetric variables, and the formulation of a scheme to increase the signal-to-noise ratio. Modeling of the polarimetric variables is based on existing back-scattering models assuming the spheroidal representation of cloud scatterers. The parameters retrieved from the model are polarizability ratio and degree of orientation, which can be assigned to certain particle orientations and shapes. The developed algorithm is applied to a measurement of the hybrid-mode cloud radar taken on 20 October 2014 in Cabauw, the Netherlands, in the framework of the ACCEPT (Analysis of the Composition of Clouds with Extended Polarization Techniques) campaign. The case study shows the retrieved polarizability ratio and degree of orientation of ice particles for a cloud system of three cloud layers at different heights. Retrieved polarizability ratios are 0.43, 0.85, and 1.5 which correspond to oblate, quasi-spherical, and columnar ice particles, respectively. It is shown that the polarizability ratio is useful for the detection of aggregation/riming processes. The orientation of oblate and prolate particles is estimated to be close to horizontal while quasi-spherical particles were found to be more randomly oriented.

description: We use time-domain numerical simulations of a two-dimensional (2D) scattering system to study the interaction of a collection of emitters resonantly coupled to an Anderson-localized mode. For a small electric field intensity, we observe the strong coupling between the emitters and the mode, which is characterized by linear Rabi oscillations. Remarkably, a larger intensity induces non-linear interaction between the emitters and the mode, referred to as the dynamical Stark effect, resulting in non-linear Rabi oscillations. The transition between both regimes is observed and an analytical model is proposed which accurately describes our numerical observations.

description: Surface acoustic waves (SAW) allow to manipulate surfaces with potential applications in catalysis, sensor and nanotechnology. SAWs were shown to cause a strong increase in catalytic activity and selectivity in many oxidation and decomposition reactions on metallic and oxidic catalysts. However, the promotion mechanism has not been unambiguously identified. Using stroboscopic X-ray photoelectron spectro-microscopy, we were able to evidence a sub-nanosecond work function change during propagation of 500 MHz SAWs on a 9 nm thick platinum film. We quantify the work function change to 455 μeV. Such a small variation rules out that electronic effects due to elastic deformation (strain) play a major role in the SAW-induced promotion of catalysis. In a second set of experiments, SAW-induced intermixing of a five monolayers thick Rh film on top of polycrystalline platinum was demonstrated to be due to enhanced thermal diffusion caused by an increase of the surface temperature by about 75 K when SAWs were excited. Reversible surface structural changes are suggested to be a major cause for catalytic promotion.

description: This work presents a comparative study on the formation of polyethersulfone ultrafiltration membranes via nonsolvent-induced phase separation (NIPS) in two different solvent systems. N-methyl-2-pyrrolidone was chosen as conventional solvent and 2-pyrrolidone as a greener alternative. The overall objective was to obtain a mechanistic clarification of the membrane formation process in dependence of the most important controlling parameters. By performing different series of experiments, it was possible to determine the differences between the two solvents regarding the effects of variations in nonsolvent additives, polymer concentration, and precipitation conditions. It was found that a raising concentration of several nonsolvents, the increase of the polymer concentration and changes in the precipitation conditions can suppress the formation of macrovoids, regardless of the applied solvent. In contrast, differences were observed with regard to the performance of the membrane prototypes. This study improves the understanding of membrane formation via NIPS and identifies the effects of different variables. It shows that the choice of the solvent is essential for the dominating formation mechanisms and therefore for the resulting membrane features. It also proves that green solvents can substitute hazardous solvents if the influencing variables are well-understood in order to control them for obtaining desired membrane properties. © 2019 The Authors.

description: We use a three-dimensional regional chemical transport model (PMCAMx) with high grid resolution and high-resolution emissions (4 × 4 km2) over the Paris greater area to simulate the formation of carbonaceous aerosol during a summer (July 2009) and a winter (January/February 2010) period as part of the MEGAPOLI (megacities: emissions, urban, regional, and global atmospheric pollution and climate effects, and Integrated tools for assessment and mitigation) campaigns. Model predictions of carbonaceous aerosol are compared against Aerodyne aerosol mass spectrometer and black carbon (BC) high time resolution measurements from three ground sites. PMCAMx predicts BC concentrations reasonably well reproducing the majority (70 %) of the hourly data within a factor of two during both periods. The agreement for the summertime secondary organic aerosol (OA) concentrations is also encouraging (mean bias = 0.1 µg m−3) during a photochemically intense period. The model tends to underpredict the summertime primary OA concentrations in the Paris greater area (by approximately 0.8 µg m−3) mainly due to missing primary OA emissions from cooking activities. The total cooking emissions are estimated to be approximately 80 mg d−1 per capita and have a distinct diurnal profile in which 50 % of the daily cooking OA is emitted during lunch time (12:00–14:00 LT) and 20 % during dinner time (20:00–22:00 LT). Results also show a large underestimation of secondary OA in the Paris greater area during wintertime (mean bias = −2.3 µg m−3) pointing towards a secondary OA formation process during low photochemical activity periods that is not simulated in the model.
Factors Affecting the Strength of Blockwork Walls Subjected to Transverse Horizontal Loading

Publisher: name: London South Bank University
Year: 1978

description: Codes of Practice and previous research concerned with the transverse lateral strength of unreinforced masonry walls is reviewed with particular reference being made to flexural strength and stiffness, shear bond, tensile bond, moisture movements and arching action. A programme of tests to investigate the flexural strength and stiffness, shear bond strength and tensile bond strength of three distinct types of blockwork masonry is described. Methods of analysing vertical spanning walls are compared and a theory based upon the stability of cracked walls is proposed. Factors affecting the tensile bond are discussed with reference to the results of more than 300 couplet tests which were carried out with three concrete block types, three moisture conditions and six mortars. Strain measurements taken across the joints in some of the couplets to determine the distribution of strain are described and methods of analysing the stresses are proposed. Measurements of moisture movements taken an a variety of test walls are presented and analysed and a hypothesis to account for a thickness factor which became apparent in the test programme is proposed. A series of arching tests is described and the results compared with predictions based on theories for uncracked and cracked walls developed as part of this research programme. The strengths of certain full sized test walls are compared with ultimate strengths calculated by various design methods. The strengths determined in accordance with the British Standard Draft Code of Practice fer Unreinforced Masonry are shown to be conservative. The thesis concludes with an Appendix which gives details of some preliminary investigations into the compressive strength of masonry specimens.
Means, Ends, and Perpetrators: Connections Between the Holocaust and the Genocide of Ethnic Poles in Volhynia and Galicia
Creators: name: Tovey, Collin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: This paper addresses the connections between the Holocaust and the massacre of ethnic Poles in Volhynia and Galicia during World War Two. It argues that the latter is a genocide and that both acts share similar methods, motivations, and perpetrators. The limited English language
scholarship on the massacre of ethnic Poles typically addresses it in the context of Polish or Ukrainian national history rather than that of comparative genocide. I consulted an interview with a Holocaust survivor and a collection of primary sources translated by Dr. Tadeusz Piotrowski.
The connections between these acts of mass killing weaken the claim that the Holocaust was an exceptional act, call for further study of smaller acts of mass killing, and emphasize the moral ambiguity of the sovereignty of nation-states.

The outcome depends on the nature of the carbene, the counter anion, and the reactant stoichiometry. The results are the basis of ongoing investigations directed towards a deprotonation of the chelated cationic complexes with a secondary phosphorus atom.

description: High-precision 3D printing technology opens to almost endless opportunities to design complex shapes present in tailored architected materials. The scope of this work is to review the latest studies regarding 3D printed lattice structures that involve the use of photopolymers fabricated by Material Jetting (MJ), with a focus on the widely used Polyjet and MultiJet techniques. The main aspects governing this printing process are introduced to determine their influence during the fabrication of 3D printed lattices. Performed experimental studies, considered assumptions, and constitutive models for the respective numerical simulations are analyzed. Furthermore, an overview of the latest extensively studied 3D printed architected lattice materials is exposed by emphasizing their achieved mechanical performances through the use of Ashby plots. Then, we highlight the advantages, limitations, and challenges of the material jetting technology to manufacture tunable architected materials for innovative devices, oriented to several engineering applications. Finally, possible approaches for future works and gaps to be covered by further research are indicated, including cost and environmental-related issues.

Subjects: classificationCode: 4703

description: This article examines the interplay between socio-spatial environments, social control mechanisms and alienated subjectivities in the urban fiction of Spanish author Ray Loriga. It analyses how the search for an urban utopia inter-twines in Loriga’s work with an attention to processes of commodification, consumerism and social control. These represented processes are read, in turn, as driving the dystopian production of dehumanized, objectified individual subjects. Focusing principally on the futuristic cities of Loriga’s 1999 novel Tokio ya no nos quiere, the discussion also draws on relevant elements of two subsequent works – El hombre que invento´ Manhattan (2004) and Rendicio´n (2017).

description: Sales revenues of enterprises are often subject to seasonal fluctuation. This leads to high or low utilized resources and this in turn to revenue losses. Hence, the enterprises invest a high effort to improve long and short-term resource utilization. In this context, disregarding future capacity utilization within the process of quotation leads to short-timed capacity adjustments for instance, additional work hours across seasons. This paper presents an approach which focuses on dependencies between costs and capacity by linking cost pricing and production scheduling. A first evaluation at an MTO supplier shows that order delays can be reduced by up to 95% and total costs by 21% compared to using the most appropriate priority rule.

description: Numerous methods have been developed to detect process anomalies during machining. Statistical approaches for semi-supervised anomaly detection compute decision boundaries using information of normal running processes for process evaluation. In this paper, two statistical approaches for semi-supervised anomaly detection in machining based on envelopes are presented and compared. The proposed parametric approach assumes normal distributed envelopes to compute decision boundaries. However, experiments show that deviations from a normal distribution can reduce the monitoring quality. The new approach is non-parametric and employs kernel density estimation (KDE) to estimate the probability density function of the envelopes. Both approaches were evaluated for several machining processes. It is found that the parametric approach is robust against high scattering processes and yields low false alarm rates. By means of the selected safety factor, the number of detected anomalies can be increased using the non-parametric approach.

description: Although the research and development of nanocomposites for almost a decade focused on structural properties, these properties remained until today far below expectations, which were forecast at the beginning of the new millennium. However, even if it is well known that the processing history has a major impact on the structure and properties of final components, this aspect was not subject of intensive research in the past. The talk focuses on the role of the manufacturing sequence on the morphology and properties of polypropylene based nanocomposites. In general it can be stated that the incorporation of nano-sized TiO2-fillers improves the some mechanical properties of the resulting nanocomposites as long as the production enables a good dispersion and distribution of the nanofiller agglomerates. However, with increasing filler loading, the morphology of injection molded parts changes: The size of the spherulites and the degree of crystallinity decreases while the crystallization/solidification proceeds faster. Simultaneously a slight improvement in the mechanical performance up to a certain filler loading can be found. However, improved mechanical properties of the nanocomposites in the final component cannot be exploited if its production in a subsequent welding step is required. The reason for the decrease in the mechanical properties is the decrease in the viscosity by the addition of the fillers, and thereby caused extreme flow processes and subsequent orientation of the fillers as well as the weakening of the filler/matrix-interphase in the welding zone. In summary, it can be observed that nanocomposites increasingly offer great opportunities for applications where single-component materials reach their limits. The key to success is the processing. Therefore it is of crucial importance that the total manufacturing history is understood and controlled. Only then it is possible to sustainably exploit the potential of polymer nanocomposites in the application.
CRACKING THE CODE: FACTORS THAT INFLUENCE ACADEMIC SUCCESS ON THE SOCIAL WORK DEGREE: A NEWLY QUALIFIED BLACK SOCIAL WORKER‟S PERSPECTIVE
Creators: name: Felix, Claire Patricia
Publisher: name: London South Bank University
Year: 2020

description: This is a qualitative study of eleven newly qualified black social workers (NQBSW) and five social work educators. The study was carried out in a post-1992 millennium university in England between 2015 and 2018. The study findings have been skilfully interpreted through the lens of a number of Bourdieu‟s thinking tools, namely „Capital‟, „Habitus‟, „Field‟ and „Knowing the Game‟. Together, they suggest that black students know how to „crack the code‟ and „Play the Game‟. The landscape may be changing for black students who historically have not performed as well as their white counterparts. However, when identities are not in threat, this group appears to perform as well as, if not better, than their white peers. This ethically approved study aimed to identify factors that influence success on a university social work degree course. The objectives were to examine behavioural factors, differences in understandings and identify types of support embraced by NQBSW participants whilst undertaking the degree. The voices of black students and their educator‟s have been documented through semi-structured person-to-person and synchronised interviews. Using interpretive phenomenology and a constructivist approach, reading, self-directed learning groups, determination, the diversity of the student population and participation were found to be influential factors for success on the degree course. Moreover, the study found that ethnicity, social forces, cultural values and the university conditions all had a role to play in the navigation of student success on the degree course.

description: We review theories of phosphorescence in cyclometalated complexes. We focus primarily on pseudooctahedrally coordinated $t_{2g}^6$ metals (e.g., [Os(II)(bpy)$_3$]$^{2+}$, Ir(III)(ppy)$_3$ and Ir(III)(ptz)$_3$) as, for reasons that are explored in detail, these show particularly strong phosphorescence. We discuss both first principles approaches and semi-empirical models, e.g., ligand field theory. We show that together these provide a clear understanding of the photophysics and in particular the lowest energy triplet excitation, T$_1$. In order to build a good model relativistic effects need to be included. The role of spin-orbit coupling is well-known, but scalar relativistic effects are also large - and are therefore also introduced and discussed. No expertise in special relativity or relativistic quantum mechanics is assumed and a pedagogical introduction to these subjects is given. It is shown that, once both scalar relativistic effects and spin-orbit coupling are included, time dependent density functional theory (TDDFT) provides quantitatively accurate predictions of the radiative decay rates of the substates of T$_1$ in phosphorescent organotranstion-metal complexes. We describe the pseudo-angular momentum model, and show that it reproduces the key experimental findings. For example, this model provides a simple explanation of the relative radiative rates of the substates of T$_1$, which differ by orders of magnitude. Special emphasis is placed on materials with potential applications as active materials in organic light-emitting diodes (OLEDs) and principles for the design of new complexes are identified on the basis of the insights provided by the theories reviewed. We discuss the remaining theoretical challenges, which include deepening our understanding of solvent effects and, vitally, understanding and predicting non-radiative decay rates.

description: Capacitive deionization (CDI) is an emerging technology for the energy-efficient removal of dissolved ions from aqueous solutions. Expanding this technology to non-aqueous media, we present an experimental characterization of a pair of porous carbon electrodes towards electrosorption of dissolved ions in propylene carbonate. We demonstrate that application of CDI technology for treatment of an organic solution with an electrochemical stability window beyond 1.2 V allows for a higher salt removal capacity and higher charge efficiency as compared to CDI applied for treatment of aqueous electrolytes. Further, we show that using conductivity measurements of the stream emerging from the CDI cell combined with an equilibrium electric double-layer structure model, we can gain insights into charge compensation mechanisms and ion distribution in carbon nanopores.

description: Using Car-Parrinello molecular dynamics we study the first reaction steps of the decomposition of a nitrogen-rich molecule and of a mixture of molecular oxygen and molecular hydrogen. Using the simulated-annealing approach we increase the temperature of the systems till they start to react. Both systems have in common that they react violently and that the precise reaction pathways, respectively the single reaction steps under the chosen conditions are largely unknown. While the first system decomposes completely within some hundred femtoseconds, the latter mixture reacts only partially on this timescale due to entropy. Complex reaction chains involving up to ten hydrogen and oxygen molecules allow for a fast reaction, but require a very specific arrangement. To our knowledge such reaction chains of neutral, stable, ground state molecules were not described before. The hope for a decomposition to nitrogen respectively to water is essentially fulfilled, but side products are observed.

description: Ocean plastic pollution is a global problem that causes ecosystem degradation. Crucial knowledge gaps exist concerning patterns in microfiber abundance across regions and ecosystems, as well as the role of these pollutants within the environment. Here, we quantified the abundance of microfibers in coral samples collected from the Belize Mesoamerican Barrier Reef System (MBRS) using a polarized light microscope and identified a subsample of these to the polymer level using an Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy microscope. Microfibers were found in all coral samples with rayon being identified as the most common microfiber, comprising 85% of quantified pollutants. We found a greater average abundance of microfibers in coral samples from the Sapodilla Cayes (296 ± SE 89) than in samples from the Drowned Cayes (75 ± SE 14), indicating spatial variation in microfiber abundance within coral tissue along the MBRS. These results demonstrate that corals on the Belize MBRS interact with microfibers and that microfiber abundance on reefs varies spatially due to point sources of pollution and local oceanography. As rayon from clothing typically enters the ocean through wastewater effluent, alterations to waste water infrastructure may prove useful in decreasing rayon pollution in coastal waters.

description: It is still true that chemical reactions can be explained by a quantum treatment of the electrons and a classical motion of the nuclei. The paper tries to make this finding more plausible by examining elementary ground and excited state reactions using Car-Parrinello and Born-Oppenheimer molecular dynamics. Several different reaction pathways leading to different products were observed for the chlor methane photoreaction, illustrating the classical chaos connected with molecular dynamics on-the-fly simulations. Kasha's rule saying that all photochemistry occurs in the first excited state is preserved one more time.
title: Assessing and managing risks from climate change in drinking water supply sources - safeguarding raw water quality through improving catchment resilience

description: Increasing temperatures and changes in precipitation patterns and amounts are expected to increase pressures on water resources and result in decreasing water quality and quantity. Water utilities face the challenge to anticipate and plan for deteriorations in the water quality of untreated abstraction sources (so-called raw water quality) and to manage consequent risks, a challenge exacerbated through deep uncertainty associated with climate change. This research proposes a framework how to integrate effects of climate change on raw water quality into risk assessment and to build capacity to anticipate and respond to change.

A national assessment of public water supply catchments in Scotland was used as a demonstration case for applying the framework. The analysis was conducted with data from 154 drinking water supply catchments from a period of 2011-2016. Empirical relationships between catchment characteristics and water quality were examined to understand overarching drivers, pressures, and underlying catchment sensitivities leading to impacts on raw water quality. Risk screenings were developed for two water quality indicators, colour and E. coli, and UKCP18-based climate and land use projections were used to identify and map catchments and areas with potential increases in risk.

The screenings identified crucial controls on water quality, high risk areas, areas of uncertainty, and allowed first suggestions for possible response options based on catchment vulnerabilities. They also provided a basis for a strategic review of and planning for the complete supply system, by providing a starting point for transferring results and insights from individual sites, and by allowing for a first appraisal of long-term sustainability of supply. By focusing on catchment integrity and resilience as a crucial part of climate change mitigation and adaptive management, this research emphasises an ecosystem-based approach as a frame for water service providers to achieve multiple objectives.

description: We analyze the Wannier-Stark spectrum of a quantum particle in tilted two-dimensional lattices with the Bloch spectrum consisting of two subbands, which could be either separated by a finite gap or connected at the Dirac points. For rational orientations of the static field given by an arbitrary superposition of the translation vectors the spectrum is a ladder of energy bands. We obtain asymptotic expressions for the energy bands in the limit of large and weak static fields and study them numerically for intermediate field strength. We show that the structure of energy bands determines the rate of spreading of a localized wave packets which is the quantity measured in laboratory experiments. It is shown that wave-packet dispersion becomes a fractal function of the field orientation in the long-time regime of ballistic spreading.

description: Biological tissues adapt to changed loading conditions through growth and remodelling (G&R) to reestablish a so-called homeostatic state. On the other hand, loading conditions above their physiological limits, as during trauma or surgical procedures, cause injury and can initiate pathological G&R. Herein, a modelling approach for G&R influenced by injury is presented combining the theories of plasticity and homogenised constrained mixtures. The results show that injury has a significant impact on the G&R behaviour and thus on the accomplishment of homeostasis.
