description: The aim of the present work is to evaluate the influence of graphene oxide (GO) on copolymer nanocomposites hydrogel structure based on acrylamide (AM) and 2-acryloamido-2-methylpropane sulfonic acid (AMPS) in the presence of the N, N-methylene-bis-acryl-amide (NMBA) by the free radical copolymerization technique. The influence of poly (AM-co-AMPS)/GO as a rheology modifier along with fluid loss controller on the rheological and mechanical properties of brine cement slurry was also investigated. The characterization results confirmed the synthesis of AM monomer and AMPS and showed their grafting with GO surface. The poly (AM-co-AMPS)/GO hydrogel improved the rheological properties of the cement slurry as compared to conventional cement slurry. Furthermore, free water and fluid loss of cement slurry declined by adding the copolymer nanocomposites hydrogel at elevated temperatures. Moreover, not only the thickening time of cement slurry dropped but also, the compressive strength increased with a rise of nanocomposites hydrogel concentrations. However, the nanocomposite hydrogels showed a great effect on early compressive strength than the final compressive strength. The results of this investigation revealed the excellent performance of crosslinked structure of copolymer nanocomposites hydrogel due to the linking of sulfonated AMPS and AM on the surface of GO nanosheet in the attendance of NMBA. This renders greater stability to the cement slurry against salinity and temperature changing of well formations during cementing operation. Thus, poly (AM-co-AMPS)/GO as a suitable rheology modifier and property enhancer can be applied in oil well cementing.

description: Despite of their importance optimal designs for quantile regression models have not been developed so far. In this paper we investigate the D-optimal design problem for the location scale nonlinear quantile regression model. We provide a necessary condition to check for the optimality of a given design and use it to determine bounds for the number of support points of locally D-optimal designs. The results are illustrated determining locally, Bayesian and standardized maximin D-optimal designs for quantile regression analysis in the Michaelis-Menten and EMAX model, where the location and the scale function are related by a known link function.

description: As ~ 50% of global photosynthesis occurs in marine environments, the factors regulating this process e.g. trace metal availability, have an impact on the global carbon cycle. The key cyanobacteria genera Prochlorococcus and Synechococcus have an absolute requirement for Co. Dissolved cobalt (dCo) concentrations in the open ocean are extremely low (5–120 pM). A sensitive flow injection technique using chemiluminescence detection (FI-CL) was developed (detection limit 4.5 pM dCo, RSD ≤ 4%). Seawater samples must be UV-irradiated prior to analysis, in order to liberate organically-bound Co. A field study in the Sargasso Sea, demonstrated that aerosol Co was significantly more soluble than aerosol Fe over a range of aerosol dust deposition fluxes (1–1040 μg Fe m-2 d-1) (8-100% for Co versus 0.44-45% for Fe). The dry deposition flux of aerosol Co was of the same order of magnitude as the advective upwelling flux (47-1540 pmol m-2 d-1 and 1.7-1430 pmol m-2 d-1 respectively). Wet deposition, dominated the total aerosol flux (~ 85%). The vertical distribution of dCo influenced Prochlorococcus abundance. A regional study in the eastern North Atlantic gyre demonstrated that the highest rates of N2 fixation occurred with the highest dFe concentrations (9.8 nM N L-1 h-1, 0.6 nM respectively). No increase in primary production following additions of trace metals (Co, Cu, Fe, Zn) was observed. The addition of N resulted in an increase in primary production. However, there was no synergistic effect of trace metal plus N addition, suggesting that alleviation of N-limitation shifted the system to P-limitation. On a meridional transect from ~ 50°N–50°S in the Atlantic Ocean, the highest concentrations of dCo (> 80 pM) coincided with low-O2 (< 150 μM) upwelled water. The lowest dCo (< 20 pM) was observed in the eastern North Atlantic gyre. Lateral advection of continental Co and upwelling were identified as important sources of Co. The highly efficient recycling of Co in the euphotic zone is an important additional source.

description: Uniform fine particles of iron oxide were precipitated in different morphologies through forced hydrolysis and co-precipitation. The effect of reaction parameters on particle uniformity and morphology was studied, and SEM analysis explored that particle morphological features were strongly affected by the applied reaction conditions. Therefore, monodispersed particles of magnetite precursors with narrow size distribution were prepared under the extensively optimized experimental parameters. The growth mechanism of the precipitated solids was observed to be sensitive to the medium temperature and pH, as high temperature and pH resulted in large particles. In contrast, small particles were precipitated at low temperatures and pH. Magnetite nanoparticles were precipitated directly through co-precipitation under controlled reaction conditions and from the calcination of the as-synthesized hematite at high temperatures. Their SEM demonstrated that calcination at high temperatures affected the particle morphology to a greater extent along with the phase transformation. Similarly, XRD and FTIR analysis of the as-prepared magnetite particles from two routes confirmed the single-phase magnetite. The response of the as-prepared particle systems to the higher temperature and composition of the surface groups was analyzed by TG/DTA and FT-IR techniques.

description: We analyze recent $K^+$ meson photoproduction data from the CLAS collaboration for the reactions $γp\rightarrow K^+Λ$ and $γp\rightarrow K^+Σ_0$, fitting measured forward-angle differential cross sections to the form $Ae^{Bt}$. We develop a quantitative scheme for determining the kinematic region where the fit is to be done, and, from the extracted $t$-slope $B$, determine whether single-Reggeon exchange can explain the production mechanism. We find that, in the region $5 < s < 8.1$ GeV$^2$, production of the $K^+Λ$ channel can be explained by single $K^+$ Reggeon exchange, but the $K^+Σ_0$ production channel cannot. We verify these conclusions by fitting the data to a differential cross section produced by the interfering sum of two exponential amplitudes.

description: Future experiments such as SHiP and high-intensity $e^+ e^-$ colliders will have a superb sensitivity to heavy Majorana neutrinos with masses below $M_Z$. We show that the measurement of the mixing to electrons and muons of one such state could imply the discovery of leptonic CP violation in the context of seesaw models. We quantify in the minimal model the CP discovery potential of these future experiments, and demonstrate that a 5$σ$ CL discovery of leptonic CP violation would be possible in a very significant fraction of parameter space.

description: The dispersion, evaluation, and exploration of behavioral science throughout its application has necessitated the characterization of metal working fluids nowadays. Alternative lubricants particularly vegetable oil-based lubes are majorly researched by the tribologists which has led to the concept of developing eco-friendly lubricants. Nano additive based veg-oil cutting fluids are outperforming most of the conventionally available metal working fluids in major aspects like friction modification, surface roughness minimization, cutting force reduction and tool wear aspects. This study focuses on evaluating the characters of bio-based (veg-oil; coconut oil-oleic acid) nano fluids with respect to two families of nano particles. Metal-oxide based and carbon-based are the two families which are usually considered. A novel concept of tri-hybridizing nano particles has been explored and the results has been evaluated and presented in a detailed manner. The size and shape morphology were studied using scanning electron microscope images. The rheological and physio-chemical properties of the prepared nano fluids like density, viscosity, thermal conductivity was also studied and presented. The behavioral analysis was performed to explore its fluidic characteristics in which contact angle, zeta potential analysis, flash point and film thickness analysis was done and presented. In addition, surface morphology studies were performed to evaluate the tribological performance of the nano fluids in end milling of AA7075. The results obtained has proved that both metal-oxide and carbonaceous nano cutting fluids are capable for tribological applications and can be considered as a proven alternative for the conventional lubricants. Around 20% improvement has been found in the cutting parameters and surface roughness.

description: This article assesses the extent to which children's language preference and their home environment matter for literacy retention. Using data from the Complementary Basic Education (CBE) program in Ghana, the authors found that large numbers of disadvantaged students reverted to not even being able to read a single word following school closures over a four-month holiday period. Widening literacy gaps were found for girls who reported they did not receive instruction in a language that they understood or did not have the resources, support, or activities at home to enable them to continue to learn while schools were closed. For boys, widening literacy gaps were only influenced by resources, support, or activities at home, but not by language preferences. The article findings suggest that schools and teachers must pay closer attention to language preference, particularly for girls, in order to ensure that language of instruction is not a barrier to literacy retention. The article also provides further evidence to support the growing claims that home supports are essential for reducing inequities in learning outcomes during school closures.

description: This study presents a comprehensive analysis of India's electricity generation trends, focusing on oil, gas,and wind energy sources, using advanced machine learning models. The research leverages data from theIndia Climate and Energy Dashboard (ICED) to explore state-wise temporal trends in electricitygeneration, aiming to provide insights into generation patterns, demand forecasting, and resourceutilization. Three datasets—wind, oil, and gas electricity generation—were analyzed using ARIMA,LSTM, and Gaussian Mixture Models (GMM) to capture temporal dependencies, seasonal trends, andregional disparities in energy production. The ARIMA and LSTM models demonstrated strongperformance in forecasting electricity generation, with LSTM showing particularly high accuracy incapturing complex temporal patterns. GMM clustering revealed significant regional disparities,highlighting states like Gujarat and Maharashtra as leaders in operational capacity. The study underscoresthe growing importance of renewable energy, particularly wind, while also emphasizing the challenges ofgrid integration and variability in generation. The findings offer valuable insights for energy planners andpolicymakers, supporting informed decision-making in resource allocation, grid management, andsustainable energy development. The research contributes to the broader goal of achieving energy securityand sustainability in India, providing a robust methodological framework for future studies in energyforecasting and optimization.
From courtship to confrontation: EU-Russia relations (1999-2008)

This thesis attempts to explain the transformation of EU-Russia relations between the Kosovo War and the end of the Putin presidency. Shortly before the outbreak of the Kosovo War, President Yeltsin had lamented that Russia was not an EU member state and began to cooperate with the EU. During the early years of the Putin era, EU-Russia relations were characterised by the emerging collaboration in energy policy and cooperation in the struggle against international terrorism. But by the end of Putin’s presidency, EU-Russia relations had deteriorated. Their summits were manifestations of clashes over Russia’s reliability as a supplier of energy resources to the EU, the withering away of Russia’s democracy and the stagnation in negotiations concerning the renewal of the EU-Russian Partnership and Cooperation Agreement. In Russia, the EU was increasingly perceived as a hostile power. The purpose of this thesis is to explain this reversal from courtship to confrontation in EU-Russia relations. The argument of the thesis revolves around the notions of 'actorness' and 'normative power'. On the one hand, this thesis seeks to demonstrate how the EU's increasing 'actorness' in the former Soviet space provoked increasing tensions with Russia. On the other hand, the thesis illuminates the contradictory effects of the EU's 'normative power.' This phenomenon served as a catalyst for closer ties under Yeltsin, who publicly advocated Russia's membership of the EU. But it provoked bitter clashes as the Putin regime tried to impose its hegemony in the post-Soviet space.

description: The thesis is about language choice, language mixing and language attitudes among Indonesian bilinguals in Australia. It is argued here that each of these features of bilingual behaviour can reveal the language maintenance situation in the Indonesian speech community, i.e. either active or passive language maintenance. The location of bilingualism investigated for language choice behaviour is the family domain. Language choice patterns in this domain have revealed that ingroup languages such as Bahasa Indonesia (BI) or the ethnic vernacular are functionally very dominant in the spouse-spouse role relationship. English is used predominantly between siblings, while other family role relationships have been characterized by language use ranging from BI to BI/English mixing and to English.[...]

description: Drawing on the term 'Australian Felix', coined by Major Thomas Mitchell in 1836, this thesis traces its obverse, a disturbing undertone in the history of Victoria that could be called 'Australia Infelix'. It draws on contemporary documentary records, including settler narratives and reminiscences, travel-writing and local histories, to argue that European settlers' imaginings and perceptions of Victoria from the period of the 1830s to the 1930s, including its indigenous culture and landscape, reveal a preoccupation, not only about placemaking, but also with displacement and dislocation. Several factors contributed to this sense of displacement: the immigrant experience, the colonial context, and the influence of inherited models for understanding the physical landscape, principally Romanticism. I show that place and history were intimately connected in the development of ideas about identity and belonging, and that the interdependence of these two notions invited feelings of melancholy, ruin and loss, which were also key themes of contemporary European Romanticism.[…]

description: Submission note: A thesis submitted in total fulfilment the requirements for the degree of Doctor of Philosophy to the Australian Research Centre in Sex, Health and Society, Faculty of Health Sciences, La Trobe University, Bundoora.

This thesis investigates the access to sexual health services and associated risk behaviours of young men in rural and regional Australia. For the purpose of my research, rural and regional men are defined as those who, at the time of this study, were aged between 16 and 25 years and were living within Rural, Remote and Metropolitan Areas (RRMA) 3 to 5 according to the RRMA classification. The specific research objectives are a) to determine the proportion of rural and regional young men who have accessed sexual health services; b) to investigate the socio-demographic determinants of access to sexual health; c) to examine the relationships between masculinity, risk perceptions and behaviours, and access to sexual health; d) to discover health providers' opinions on major barriers, and e) to determine whether or not masculinity is acknowledged in the health policies and by the service providers. This research was undertaken in two stages. I used both quantitative and qualitative methodologies to collect data for my research. The quantitative method (Study One) addressed research objectives a), b) and c) and used an online survey. Three hundred and ninety-six participants were recruited from three regional Technical and Further Education Institutes. Qualitative methods (Study Two) were used to fulfil research objectives d) and e) through 11 key informant interviews. While most of the participants indicated that they were sexually active, had engaged in sex, and exhibited drug-and alcohol-related risk behaviours, their risk perceptions of becoming infected with sexually transmissible infections were low. The majority of the participants did not access sexual health services although general practitioners and community health nurses were considered the most trusted source of advice on sexual health matters. A quantitative measure of hegemonic masculinity was found to be associated with certain risk behaviours and was associated with the participants’ confidence in visiting a health service provider and access to health services for general health problems, but not with access to sexual health services. Key informants perceived that dominant masculine beliefs are associated with risk behaviours of young men and identified remoteness, opening hours, stigma and gender of the health provider as major barriers for the provision of sexual health services for rural young men in Australia.

Анохина, а также антипереходы и узлы в модели Сфираль. Оба подхода описывают мышление как нелинейную, фрактальную динамику переходов, в которой смысл возникает не в элементах, а в точках сопряжения между ними. Хаб интерпретируется как функциональный эквивалент узла инверсии; кротовая нора — как антипереход между удалёнными когами. Предлагается рассматривать озарение и ассоциативный скачок не как аномалии, а как проявления внутренней топологии сознания. Статья открывает путь к интеграции когнитомной нейронауки с топологическими моделями мышления и смыслообразования.

description: Magneto-optical Kerr effect (MOKE) microscopy measurements of magnetic bubble domains demonstrate that Ar+ irradiation around 100 eV can tune the Dzyaloshinskii-Moriya interaction (DMI) in Pt/Co/Pt trilayers. Varying the irradiation energy and dose changes the DMI sign and magnitude separately from the magnetic anisotropy, allowing tuning of the DMI while holding the coercive field constant. This simultaneous control emphasizes the different physical origins of these effects. To accurately measure the DMI, we propose and apply a physical model for a poorly understood peak in domain wall velocity at zero in-plane field. The ability to tune the DMI with the spatial resolution of the Ar+ irradiation enables new fundamental investigations and technological applications of chiral nanomagnetics.

description: E+A galaxies are post-starburst systems that are identified from their optical spectra. These galaxies contain a substantial young A-type stellar component, but have only little ongoing star formation (SF). HI 21-cm line emission is found in approximately half of the nearby E+A galaxies, indicating that they contain a reservoir of gas that could fuel active SF. Here, we study two HI-rich galaxies, which show a typical E+A spectrum at the centre and SF at larger radii. We present new high spatial resolution radio interferometric observations of the HI 21-cm emission line using the VLA and of the CO(1-0) emission line using ALMA. We combine these data sets to predict the SFR and show that it does not correlate well with the SFR derived from H alpha on sub-kpc scales. We apply a recently developed statistical model for the small scale behaviour of the SF relation to predict and interpret the observed scatter. We find smoothly distributed, regularly rotating HI gas. The CO(1-0) emission line is not detected for both galaxies. The derived upper limit on the CO mass implies a molecular gas depletion time shorter than 20 Myr. However, due to the low metallicity, the CO-to-H2 conversion factor is highly uncertain. In the relations between the H alpha-based SFR and the HI mass, we observe a substantial scatter we demonstrate results from small-number statistics of independent star-forming regions on sub-kpc scales. This finding adds to the existing literature reporting a scale dependence of the molecular SF relation, showing that the atomic and molecular phases are both susceptible to the evolutionary 'cycling' of individual regions. This suggests that the atomic gas reservoirs host substantial substructure, which should be observable with future high-resolution observations. (abridged)

description: We investigate interference and correlation effects when several detuned emitters are placed along a one-dimensional photonic waveguide. Such a setup allows multiple interactions between the photons and the strongly coupled emitters, and underlies proposed devices for quantum information processing. We show, first, that a pair of detuned two-level systems (2LS) separated by a half wavelength mimic a driven Λ-type three-level system (3LS) in both the single- and two- photon sectors. There is an interference-induced transparency peak at which the fluorescence is quenched, leaving the transmitted photons completely uncorrelated. Slightly away from this separation, we find that the inelastic scattering (fluorescence) is large, leading to nonlinear effects such as non-reciprocity (rectification). We connect this non-reciprocity to inelastic scattering caused by driving a dark pole and so derive a condition for maximum rectification. Finally, by placing a true 3LS midway between the two 2LS, we show that elastic scattering produces only transmission, but inelastic scattering nevertheless occurs (the fluorescence is not quenched) causing substantial photon correlations.

Some aspects of manufacturing development in Melbourne, 1870 to 1890
Creators: name: Tasman George Parsons

Subjects: History

description: Although Australia is a highly urbanised society displaying considerable manufacturing development, most historians have neglected the city and the factory in their explanations of Australia 1 s evolution in the second half of the nineteenth century. There is, however, growing recognition of the need to correct conventional accounts by systematic attention to urbanisation and manufacturing.

This thesis is an examination of manufacturing enterprise in the city of Melbourne during the years of the "long-boom", 1870 to 1890. The study is in three parts. In Part 1, six chapters deal with the general aspects of manufacturing development in the Victorian capital, concentrating on economic conditions, the location of industry, the role of the tariff, the level of technological development, and the significance of state intervention. It is argued that during the 1870s manufacturing in Melbourne grew rapidly, because of a process of import replacement , reinforced by government action in reserving contracts for colonial industrialists . Output expanded rapidly in the 1870s, but in the 1880s manufacturing development slowed because expansion was now limited by the growth of the domestic market. Urban-based industries dominated the "land boom" decade in Victoria . The tariff, which was designed ii primarily for revenue and only incidentally for protection, played only a small role in manufacturing development. This conclusion is supported by a study of tariff legislation, calculations of effective protective rates, and freight rates for key products (Chapter 4). Chapter 5 demonstrates the importance of government aid for the manufacturers of Melbourne. The study of technological innovation {Chapter 6) shows that the leading industries were those linked to the agricultural sector (e.g. agricultural implements and machinery) and those which were urban-based and consum.eroriented (e.g. brewing, flour milling). In general, it is argued that the strength of the forward-link~ge industries has been seriously underestimated. [...]

description: This three-year research project began in January 2014 and investigated whether, during the Victorian period, the professions formed a distinct self-sustaining social group with its own mores and values. The project looked at 16,000 individuals drawn from census data for Alnwick, Brighton, Bristol, Dundee, Greenock, Leeds, Merthyr Tydfil, Morpeth, and Winchester. The research project was funded by the UK Economic & Social Research Council and was based at the Universities of Oxford and Northumbria.
Causality in thermoelectric systems: Insights from block diagrams
Creators: name: Apertet, Y.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: While Carnot's model engines demonstrate ideal performances regarding conversion efficiency, they cannot be actually used as energy converters since they are non causal systems. Such an unphysical behavior indeed restrains the working conditions to a single point where, in the case of a refrigerator (generator), the cooling power (output power) vanishes. Focusing on the example of a thermoelectric refrigerator, we study the impact of different dissipation sources on the causality of such systems. Basing our analysis on the block diagram description of this system, we discuss particularly the fact that heat conduction cannot ensure causality.

description: The saxophone quartet is large an underdeveloped area of study, especially in Australia. While there are numerous quartets performing throughout the country, research into contemporary literature is limited. Therefore the study aims to focus on two works that represent the Australian contemporary genre. These works are Barbara Woof's Hymns and Melodies (1989) and Brigid Burke's Shake A Bud (2001).[…]

description: The effect of the collector and its blends on sequential flotation of a complex lead-zinc ore has been investigated. Lead-zinc ore collected from Rajasthan, India showed the presence of PbS-2.21%, ZnS-5.92%, FeS2-8.03%, SiO2-20.21%, Al2O3-5.25%, MgO-10.53%, SO3-6.48% and CaO-22.16%. The copper and silver were also traced as minor fractions. Xanthates of different alkyl chain lengths as a collector (individual or mixture in various proportions) were used in the lead circuit to evaluate valuables’ performance in the mineralized pulp. The study could enhance the lead and zinc grade up to 27.95% and 22.6% using PEX (potassium ethyl xanthate) and SIPX (sodium isopropyl xanthate) as a blend. The best overall performance in the recovery of lead and zinc was 74.39% and 82.23%, respectively. However, the studies carried out with individual collectors, PEX and SIPX, showed their best result: 22.06% lead and 20.99% zinc grade, 60.54% lead, and 78.73% zinc recovery. The study confirms the synergies between the two alkyl chain length xanthates in the blend.
A 'New Look' ALP? The Middle Classing of the Victorian Branch of the ALP 1961-1982

description: The chief purpose of this thesis is to establish that the ALP has, in recent decades, attracted a sizeable middle-class membership. Of course others have suggested that it has, but their claims have usually been based upon observed changes in the composition of the parliamentary ALP, or in the style of its parliamentary leaders. Until now the rank and file who make up the vast majority of ALP members have been paid little or no sociological attention. Using membership records pertaining to the Victorian Branch of the ALP, I am able to show that Labor no longer has a largely blue-collar membership, and that between 1961 and 1981, it attracted a sizeable number of middle-class recruits.[…]
Nonlinear dynamics of hidden modes in a system with internal symmetry

description: We consider a discrete dynamical system with internal degrees of freedom (DOF). Due to the symmetry between the internal DOFs, certain internal modes cannot be excited by external forcing (in a case of linear interactions) and thus are considered "hidden". If such a system is weakly asymmetric, the internal modes remain approximately "hidden" from the external excitation, given that small damping is taken into account. However, already in the case of weak cubic nonlinearity, these hidden modes can be excited, even as the exact symmetry is preserved. This excitation occurs through parametric resonance. Floquet analysis reveals instability patterns for the explored modes. To perform this analysis with the required accuracy, we suggest a special method for obtaining the Fourier series of the unperturbed solution for the nonlinear normal mode. This method does not require explicit integration of the arising quadratures. Instead, it employs expansion of the solution at the stage of the implicit quadrature in terms of Chebyshev polynomials. The emerging implicit equations are solved by using a fixed-point iteration scheme. Poincaré sections help to clarify the correspondence between the loss of stability of the modes and the global structure of the dynamical flow. In particular, the conditions for intensive energy exchange in the system are characterized.

description: Oil-in-water-in-oil (O1/W/O2) emulsions and nanoemulsions based on extra virgin olive oil were produced combining high-speed and ultrasonic homogenizer. Droplet size distribution, encapsulation efficiency, kinetic stability, and their structure were studied as a function of homogenization time, dispersed volume fraction, emulsifier type, and composition of the inner O1/W nanoemulsion. The ultrasonic-assisted homogenization was beneficial for the formation of O1/W/O2 nanoemulsion, as the intensity of the ultrasound did not destroy the double structure. The inner O1/W nanoemulsion with the lowest droplet size, surface tension, and viscosity resulted in double nanoemulsion with the minimum droplet size (432 ± 5 nm). Increasing the dispersed volume fraction resulted in higher particle size, gravitational separation, and high oiling off values. The DSC thermograms showed samples with the low droplet size presented also low encapsulation yield. The microscopic analysis demonstrated that all O1/W/O2 samples showed similar structures with distinctly visible phases and spherical aqueous droplets with a broad distribution.
