Biocementation of an Organic Soil with Electrokinetics
Creators: name: Safdar, Muhammad Umair
Publisher: name: London South Bank University
Year: 2020

description: This thesis assesses the feasibility of biocementation of a problematic organic foundation soil of many embankments of the East Anglia railway network. Biocementation has recently attracted the interest of the researchers worldwide as an emerging soil stabilisation technique, proposed as environmentally friendlier and more sustainable than other soil stabilisation techniques; however, evidence of its effectiveness as a stabilisation technique for soils other than sands is limited. In this research indigenous, non-pathogenic and ureolytic bacterial strains were screened and isolated from the in situ soil. Four strains (Bacillus licheniformis, Rhodococcus erythropolis, Micrococcus luteus, and Lysinibacillus fusiformis) were selected based on their ability to grow at different temperatures, pH, soil moisture content and to precipitate CaCO3 through urea hydrolysis. For the implementation of the biocementation treatment, laboratory scale models were designed for pressure flow column and electrokinetic injection. The latter method was of particular interest in this study as a potential in situ implementation method under existing embankments. After a first series of pressure flow soil column experiments, with all strains, which studied parameters such as bacterial population and cementation reagent concentration and curing time. Following these, the best performing strain (Bacillus licheniformis) in terms of Unconfined Compressive Strength (UCS) and CaCO3 precipitation (in the flow column tests) was used for further testing and the electrokinetic experiments. Unconfined Compressive Strength (UCS) and oedometer testing results supported by CaCO3 measurements, NH4 + concentration measurements and pH change measurements, as well as microstructural SEM-EDS analysis, proved that biocementation did occur for both implementation methods and for a number of treatment combinations. EK was the most successful implementation method and was proven effective for degrees of saturation of 85-95%. Whilst treatment non-uniformity when bacteria were injected electrokinetically still needs to be addressed, there is promise that EK could be a viable technique for treating foundation soil under existing infrastructure, which is a major challenge for engineers.

description: We study quasiparticle tunneling in Josephson tunnel junctions embedded in an electromagnetic environment. We identify tunneling processes that transfer electrical charge and couple to the environment in a way similar to that of normal electrons, and processes that mix electrons and holes and are thus creating charge superpositions. The latter are sensitive to the phase difference between the superconductor and are thus limited by phase diffusion even at zero temperature. We show that the environmental coupling is suppressed in many environments, thus leading to lower quasiparticle decay rates and thus better superconductor qubit coherence than previously expected. Our approach is nonperturbative in the environmental coupling strength.

description: While the efficacy of salvaging underutilised historical buildings to promote sustainable and resilient provincial urban areas in New Zealand has been identified from past studies, there is still an absence of a performance-based framework to rank optimal historical building alternatives for adaptive reuse interventions. This paper focuses on evaluating a performance-based Multiple Criteria Decision Assessment (MCDA) methodology to prioritise underutilised historical buildings for adaptive reuse intervention in a major provincial area in New Zealand, towards achieving a resilient town-centre regeneration for the area. A focus group workshop was conducted with relevant stakeholders involved in an existing town centre regeneration agenda for Whanganui, to explore and balance their opinions for optimal selection of a vacant historical building for adaptive reuse intervention from a group of proposed buildings. The participant mix comprised a combination of building professionals, historical building owners/developers/users, legal, heritage, and council/community representatives. The findings establish the usefulness of the validated framework in balancing the diverse interests of all stakeholders in the adaptive reuse decision-making process. Hence, this paper provides a significant contribution to the development of a methodology that integrates adaptive reuse stakeholders’ diversified interests, for the selection of optimal case study building alternatives. The consensus of the multidisciplinary stakeholder group was found to be consistent and insensitive to reasonable changes in weighting. Also, the validated framework enabled the decision-makers to achieve a logical result, and support the visualisation of the impact of different priority aspects and criteria on adaptive reuse interventions in New Zealand.

description: This work presents a behavior planning algorithm for automated driving in urban environments with an uncertain and dynamic nature. The algorithm allows to consider the prediction uncertainty (e.g. different intentions), perception uncertainty (e.g. occlusions) as well as the uncertain interactive behavior of the other agents explicitly. Simulating the most likely future scenarios allows to find an optimal policy online that enables non-conservative planning under uncertainty.

description: Children are particularly vulnerable to the health effects of air pollution and as they spend a large proportion of time at school, this is an important environment for children's exposure to air pollution. Understanding the factors that influence indoor air quality in schools is critical for the assessment and control of indoor air pollution. This study analysed the concentration and sources of air pollution at an urban primary school (5–11 years) in Wellington, the capital of New Zealand. Over a three-week period during spring, indoor measures of particulate matter (PM 2.5 , PM 10 ), temperature, humidity, carbon dioxide (CO 2 ) and nitrogen dioxide (NO 2 ) were taken and hourly air particulate matter samples (PM 2.5 , PM 10-2.5 ) were collected inside and outside for elemental speciation analysis. Indoor PM 10 concentrations during the school day were significantly (p < 0.001) higher than outdoor concentrations 30.1 (range 10.0–75.0, SD 1.9) μg m −3 c.f. 8.9 (range <1.0–35.0, SD 6.8) μg m −3 . Elemental analysis and receptor modelling of PM samples showed that indoor PM 10 was primarily composed of crustal matter (soil) elements, possibly brought in on children's footwear. The primary driver of indoor PM 2.5 was from the infiltration of outdoor pollutants inside, with by-products of motor vehicle emissions the main contributor to indoor PM 2.5 . There is a need for mitigation strategies to reduce exposure to indoor air pollution at school, such as improved cleaning methods, reducing the use of carpet in schools and improved ventilation. The findings from this study will be applicable to many other schools and public buildings with high foot traffic.

description: Hamiltonian systems can be classified into ten classes, in terms of the presence or absence of time-reversal symmetry, particle-hole symmetry and sublattice/chiral symmetry. We construct a quantum coherent scattering theory of linear transport for coupled electric, heat and spin transport; including the effect of Andreev reflection from superconductors. We derive a complete list of the Onsager reciprocity relations between transport coefficients for coupled electric, spin, thermoelectric and spin caloritronic effects. We apply these to all ten symmetry classes, paying special attention to specific additional relations that follow from the combination of symmetries, beyond microreversibility. We discuss these relations in several illustrative situations. We show the reciprocity between spin-Hall and inverse spin-Hall effects, and the reciprocity between spin-injection and magnetoelectric spin currents. We discuss the symmetry and reciprocity relations of Seebeck, Peltier, spin-Seebeck and spin-Peltier effects in systems with and without coupling to superconductors.

description: The primordial perturbation is widely accepted to be generated through the vacuum fluctuation of the scalar field which drives inflation. It is, however, not completely clear what is the natural vacuum in the inflationary universe particularly in the presence of non-linear interactions. In this series of papers, we will address this issue, focusing on the condition required for the removal of the divergence from the infrared (IR) contribution to loop diagrams. We show that requesting the gauge invariance in the local observable universe guarantees the IR regularity of the loop corrections beginning with a simple initial state. In our previous works, the IR regularity condition was discussed using the slow roll expansion, which restricts the background evolution of the inflationary universe. We will show more generally that requesting the gauge invariance/the IR regularity leads to non-trivial constraints on the allowed quantum states.

description: Owing to the enormous interest the rapidly growing field of topological states of matter (TSM) has attracted in recent years, the main focus of this review is on the theoretical foundations of TSM. Starting from the adiabatic theorem of quantum mechanics which we present from a geometrical perspective, the concept of TSM is introduced to distinguish gapped many body ground states that have representatives within the class of non-interacting systems and mean field superconductors, respectively, regarding their global geometrical features. These classifying features are topological invariants defined in terms of the adiabatic curvature of these bulk insulating systems. We review the general classification of TSM in all symmetry classes in the framework of K-Theory. Furthermore, we outline how interactions and disorder can be included into the theoretical framework of TSM by reformulating the relevant topological invariants in terms of the single particle Green's function and by introducing twisted boundary conditions, respectively. We finally integrate the field of TSM into a broader context by distinguishing TSM from the concept of topological order which has been introduced to study fractional quantum Hall systems.

description: Alors qu’il existait depuis la fin des années 90, le concept de « Santé mondiale » fait aujourd’hui partie du langage courant des experts de la santé publique internationale, mais comment caractériser cette approche ? Parce qu’elles transcendent les frontières, parce qu’elles appellent à des actions collectives et coordonnées au niveau mondial et parce qu’elles nécessitent une approche triplement transversale (multidisciplinaire, multi-acteurs et multisectorielle), les épidémies de sida et de Covid-19 illustrent parfaitement, chacune à sa façon, cette nouvelle approche. On peut considérer que la lutte contre le sida a été, d’une certaine façon, un laboratoire de la santé mondiale. En provoquant, avec d’autres, la réorganisation de l’architecture internationale de l’aide en santé, en stimulant l’émergence de nouveaux acteurs sur la scène internationale, en contribuant à l’éclatement des frontières et des disciplines, le sida a certainement été un accélérateur de cette nouvelle façon de penser les questions de santé. La crise de la Covid-19 transforme l’essai et oblige la communauté internationale à prendre conscience de ce nouvel impératif : nous n’avons pas d’autres choix que la santé mondiale, la coopération et la solidarité à l’échelle de la planète.

description: Using five basic principles we treat Gerstenhaber/Lie brackets, BV operators and Master equations appearing in mathematical and physical contexts in a unified way. The different contexts for this are given by the different types of (Feynman) graphs that underlie the particular situation. Two of the maxims we bring forth are (1) that extending to the non-connected graphs gives a commutative multiplication forming a part of the BV structure and (2) that there is a universal odd twist that unifies and explains seemingly ad hoc choices of signs, and is responsible for the BV operator being a differential. Our treatment results in uniform, general theorems. These allow us to prove new results and recover and connect many constructions that have appeared independently throughout the literature. The more general point of view also allows us to disentangle the necessary from the circumstantial.

description: Lehrkräfte sind mehr denn je gefordert, digitale Medien in Ihrem Unterricht einzusetzen, um Lernenden sowohl digitale Kompetenzen zu vermitteln als auch lernwirksamen Fachunterricht mit digitalen Medien zu gestalten (z. B. KM Bayern, 2022). Mathematisches Wissen (ohne Technologiebezug) wird als wichtige Voraussetzung für den Aufbau fachdidaktischen Wissens diskutiert, welches wiederum den Lernerfolg beeinflusst (Kleickmann et al., 2013). In ähnlicher Weise ließe sich auch annehmen, dass technologiebezogenes Fachwissen, wie es beispielsweise im TPACK-Modell (Koehler & Mishra, 2009) beschrieben wird, eine Voraussetzung für den Aufbau technologiebezogenen fachdidaktischen Wissens und damit für den lernwirksamen Fachunterricht mit digitalen Medien ist. Studien mit objektiven Wissensmaßen sind in diesem Bereich jedoch kaum vorhanden (Petko, 2020). Ziel dieses Beitrags ist es, das technologiebezogene mathematische Wissen von aktiven Mathematiklehrkräften an weiterführenden Schulen mit Hilfe eines neu entwickelten Messinstruments zu beschreiben.

This bound improves the previous one $(3-\frac{1}{p+1})n^2-\big(1+2p\binom{2p}{p}\big)n$ due to Landsberg. Furthermore our bound improves the classic bound $\frac{5}{2}n^2-3n$, due to Bläser, for every $n\geq 132$. Finally, for $p = 2$, with a sligtly different strategy we menage to obtain the lower bound $\frac{8}{3}n^2-7n$ which improves Bläser's bound for any $n\geq 24$.

Here, we consider both q- and the κ-Gaussians for fit onto the Raman spectrum of diamond. In the case of diamond, some fit examples obtained with the Kaniadakis exponents are providing a better result.

description: We study the entanglement properties of a quantum lattice-gas model for which we can find the exact ground state (of the Rokhsar-Kivelson type). The ground state can be expressed as a superposition of states, each of which is characterized by a particle configuration with nearest-neighbor exclusion. We show that the reduced density matrix of the model on a ladder is intimately related to the transfer matrix of the classical hard-square model. The entanglement spectra of the model on square and triangular ladders are critical when parameters are chosen so that the corresponding classical hard-square models are critical. A detailed analysis reveals that the critical theories for the entanglement Hamiltonians are $c<1$ minimal conformal field theories. We further show that the entanglement Hamiltonian for the triangular ladder is integrable despite the fact that the original quantum lattice-gas model is non-integrable.

description: By incorporating market impact and asymmetric sensitivity into the evolutionary minority game, we study the coevolutionary dynamics of stock prices and investment strategies in financial markets. Both the stock price movement and the investors' global behavior are found to be closely related to the phase region they fall into. Within the region where the market impact is small, investors' asymmetric response to gains and losses leads to the occurrence of herd behavior, when all the investors are prone to behave similarly in an extreme way and large price fluctuations occur. A linear relation between the standard deviation of stock price changes and the mean value of strategies is found. With full market impact, the investors tend to self-segregate into opposing groups and the introduction of asymmetric sensitivity leads to the disappearance of dominant strategies. Compared with the situations in the stock market with little market impact, the stock price fluctuations are suppressed and an efficient market occurs. Theoretical analyses indicate that the mechanism of phase transition from clustering to self-segregation in the present model is similar to that in the majority-minority game and the occurrence and disappearance of efficient markets are related to the competition between the trend-following and the trend-aversion forces. The clustering of the strategies in the present model results from the majority-wins effect and the wealth-driven mechanism makes the market become predictable.

description: Tributylphosphate (TBP) has been reliably used in the solvent extraction of actinides for decades. One current application of TBP is the purification of plutonium-238 (238Pu), a heat source for radioisotope thermoelectric generators. Part of the 238Pu production process includes irradiating neptunium-237 (237Np) previously purified using di-(2-ethylhexyl)phosphoric acid (HDEHP). However, radiolytic decomposition of TBP and HDEHP forms several problematic phosphate-based degradation products. These non-incinerable byproducts contaminate the final 238Pu product and complicate the recycle of 237Np. In contrast, alternative extractants, such as the N,N-diakylamides, have incinerable byproducts. Nonbranched N,N-dialkylamides (N,N-dihexylhexanamide (DHHA) and N,N-dihexyloctanamide (DHOA)) and branched N,N-dialkylamides (N,N-di(2-ethylhexyl)butanamide (DEHBA) and N,N-di(2-ethylhexyl)isobutanamide (DEHiBA)) were considered for Np/Pu and Np/Th separations to replace TBP or HDEHP in 238Pu production. To understand the extraction potential of N,N-dialkylamides, all four N,N-dialkylamides were used to extract actinides (Th, U, Np, Pu, Am) across a range of solution-accessible oxidation states. Those results were then compared based on the actinides’ oxidation state (III - VI) to illustrate some of the similarities and differences in extraction behavior.

description: As a minimal fermionic model with kinetic frustration, we study a system of spinless fermions in the lowest band of a triangular lattice with long-range repulsion. We find that the combination of interactions and kinetic frustration leads to spontaneous symmetry breaking in various ways. Time-reversal symmetry can be broken by two types of loop current patterns, a chiral one and one that breaks the translational lattice symmetry. Moreover, the translational symmetry can also be broken by a density wave forming a kagome pattern or by a Peierls-type trimerization characterized by enhanced correlations among the sites of certain triangular plaquettes (giving a plaquette-centered density wave). We map out the phase diagram as it results from leading order Ginzburg-Landau mean-field theory. Several experimental realizations of the type of system under study are possible with ultracold atoms in optical lattices.

description: Previous studies (Sparavigna, 2023) have demonstrated the Tsallis q-Gaussian functions suitable for the analysis of Raman spectra. These functions can be used for simulating the different line shapes of Raman bands. Besides the q-Gaussian, another generalized Gaussian form can be investigated for Raman spectroscopy; it is the Kaniadakis κ-Gaussian probability density function, which contains the κ-exponential. Here, we consider both q- and κ-Gaussians for fitting onto the Raman spectrum of diamond. In the case of diamond, some fitting examples obtained with the Kaniadakis exponents are providing a better result, for the behavior of the far wings of the line. Comparison with pseudo-Voigt line shape is also proposed and a pseudo-Voigtian function made of a linear combination of two q-Gaussians is proposed too.

Excursion set peaks: a self-consistent model of dark halo abundances and clustering

description: We describe how to extend the excursion set peaks framework so that its predictions of dark halo abundances and clustering can be compared directly with simulations. These extensions include: a halo mass definition which uses the TopHat filter in real space; the mean dependence of the critical density for collapse delta_c on halo mass m; and the scatter around this mean value. All three of these are motivated by the physics of triaxial rather than spherical collapse. A comparison of the resulting mass function with N-body results shows that, if one uses delta_c(m) and its scatter as determined from simulations, then all three are necessary ingredients for obtaining ~10% accuracy. E.g., assuming a constant value of delta_c with no scatter, as motivated by the physics of spherical collapse, leads to many more massive halos than seen in simulations. The same model is also in excellent agreement with N-body results for the linear halo bias, especially at the high mass end where the traditional peak-background split argument applied to the mass function fit is known to underpredict the measured bias by ~10%. In the excursion set language, our model is about walks centered on special positions (peaks) in the initial conditions -- we discuss what it implies for the usual calculation in which all walks contribute to the statistics.

Evolutionary Tracks of Trapped, Accreting Protoplanets: the Origin of the Observed Mass-Period Relation

description: The large number of observed exoplanets ($\gtrsim $ 700) provides important constraints on their origin as deduced from the mass-period diagram of planets. The most surprising features in the diagram are 1) the (apparent) pile up of gas giants at a period of $\sim 500$ days ($\sim1$ AU) and 2) the so-called mass-period relation which indicates that planetary mass is an increasing function of orbital period. We construct the evolutionary tracks of growing planets at planet traps in evolving protoplanetary disks and show that they provide a good physical understanding of how these observational properties arise. The fundamental feature of our model is that inhomogeneities in protoplanetary disks give rise to multiple (up to 3) trapping sites for rapid (type I) planetary migration of planetary cores. The viscous evolution of disks results in the slow radial movement of the traps and their cores from large to small orbital periods. In our model, the slow inward motion of planet traps is coupled with the standard core accretion scenario for planetary growth. As planets grow, type II migration takes over. Planet growth and radial movement are ultimately stalled by the dispersal of gas disks via photoevaporation. Our model makes a number of important predictions: that distinct sub-populations of planets that reflect the properties of planet traps where they have grown result in the mass-period relation; that the presence of these sub-populations naturally explains a pile-up of planets at $\sim 1$ AU; and that evolutionary tracks from the ice line do put planets at short periods and fill an earlier claimed "planet desert" - sparse population of planets in the mass-semi-major axis diagram.

description: An almost quaternion-Hermitian structure on a Riemannian manifold $(M^{4n},g)$ is a reduction of the structure group of $M$ to $\mathrm{Sp}(n)\mathrm{Sp}(1)\subset \mathrm{SO}(4n)$. In this paper we show that a compact simply connected homogeneous almost quaternion-Hermitian manifold of non-vanishing Euler characteristic is either a Wolf space, or $\mathbb{S}^2\times \mathbb{S}^2$, or the complex quadric $\mathrm{SO}(7)/\mathrm{U}(3)$.

The coupling between the core/cusp and missing satellite problems

description: We calculate the energy that baryons must inject in cold dark matter (CDM) haloes in order to remove centrally-divergent DM cusps on scales relevant to observations of dwarf spheroidal galaxies (dSphs). We estimate that the CDM haloes often associated with the Milky Way's dSphs (M_vir/M_\odot \sim 10^{9-10}) require ΔE/erg \sim 10^{53-55} in order to form cores on scales comparable to the luminous size of these galaxies. While supernova type II (SNeII) explosions can in principle generate this energy, the actual contribution is limited by the low star formation efficiency implied by the abundance of luminous satellites. Considering that CDM's well-known `core/cusp' and `missing satellite' problems place opposing demands on star formation efficiencies, existing observational evidences for large cores in the most luminous dSphs require that CDM models invoke some combination of the following: (i) efficient (of order unity) coupling of SNeII energy into dark matter particles, (ii) star formation histories peaking at unexpectedly high redshifts (z>6), (iii) a top-heavy stellar IMF, and/or (iv) substantial satellite disruption or other stochastic effects to ease the substructure abundance constraints. Our models show that the tension between CDM problems on small scales would increase if cored DM profiles were to be found in fainter dwarves.
