description: The RAYSOLAR project was born in 2007 in order to develop and build a new purification system
for solar-grade silicon via the metallurgical route with low energy consumption and low cost. The main goal was to
setup a single system where all the required processes for silicon refining (including simultaneous removal of metal
and dopant impurities) could be done, in order to have an extremely simplified solar-grade silicon production
equipment. At present time a process and equipment for upgraded metallurgical silicon has been developed and
tested on lab scale. The process has a very lo power consumption, does not use slags and is environmentally safe.
Based on lab results a pilot line with less than 10 kWh/kg consumption is under construction.
Becoming an English Teacher: The Shaping of Everyday Professional Experiences in Early Career Teaching
Creators: name: OWEN, CERIDWEN CECILIA
Publisher: name: Monash University
Year: 2020
Subjects: Other education not elsewhere classified

description: This study examines the everyday work and development of nine early career English teachers in Victoria, Australia. In an education context characterised by standards-based reforms, the ethnographic accounts of these teachers illustrate ways they were working with, negotiating and resisting the imperatives of standardisation, accountability and oversight. Alongside standards-based approaches to teacher development based on decontextualised skills and knowledge, these accounts show that teacher development is also affective, ethical and inherently social. The study advocates for governments, universities and education systems to reconsider the developmental supports offered to beginning English teachers, including support for discipline-specific, ongoing and collaborative professional communities.

description: An increasing number of theoretical calculations on few-layer materials have been reporting a non-zero sound velocity for all three acoustic phonon modes. In contrast with these reports, here we show that the lowest phonon dispersion branch of atomistically described few-layer materials should be quadratic, and this can have dramatic consequencies on calculated properties, such as the thermal conductivity. By reformulating the interatomic force constants (IFC) in terms of internal coordinates, we find that a delicate balance between the IFCs is responsible for this quadraticity. This balance is hard to obtain in ab-initio calculations even if all the symmetries are numerically enforced a posteriori, but it arises naturally in our approach. We demonstrate the phenomenon in the case of borophene, where a very subtle correction to the ab-initio IFCs yields the physically correct quadratic dispersion, while leaving the rest of the spectrum virtually unmodified. Such quadraticity nevertheless has a major effect on the computed lattice thermal conductivity, which in the case of borophene changes by more than a factor 2, and reverses its anisotropy, when the subtle IFC correction is put in place.
A note on the Akemann-Doner and Farah-Wofsey constructions

description: We remove the assumption of the continuum hypothesis from the Akemann-Doner construction of a non-separable $C^*$-algebra $A$ with only separable commutative $C^*$-subalgebras. We also extend a result of Farah and Wofsey's, constructing $\aleph_1$ commuting projections in the Calkin algebra with no commutative lifting. This removes the assumption of the continuum hypothesis from a version of a result of Anderson. Both results are based on Luzin's almost disjoint family construction.

description: Quantum field theory provides us with the means to calculate scattering amplitudes. In recent years a dramatic new development has lead to great simplification of such calculations. This is based on the discovery of the``amplituhedron'' in the context of scattering of massless gauge bosons in Yang-Mills theory. One of the main challenges facing Loop Quantum Gravity is the lack of a clear description of particle scattering processes and a connection to flat space QFT. Here we show a correspondence between the space of kinematic data of the scattering $ N $ massless particles and $ U(N) $ coherent states in LQG. This correspondence allows us to provide the outlines of a theory of quantum gravity based upon the dynamics of excitations living on the the positive Grassmannian.

description: Challenging behaviour in the classroom is a concern for teachers, parents and community in Indonesia. The study provided new insights into how teachers perceive and respond to challenging behaviours in one region of the country. The study revealed some factors that could be integrated into a professional learning program so that teachers use more positive and proactive classroom management strategies. Teachers will need ongoing support and training to improve their knowledge and skills to use effective classroom management practice. A series of implications are identified that may have significance for policymakers, teacher educators and researchers in Indonesia and beyond.

description: We embark on a study of quasi-periodic pulsations (QPPs) in the decay phase of white-light stellar flares observed by Kepler. Out of the 1439 flares on 216 different stars detected in the short-cadence data using an automated search, 56 flares are found to have pronounced QPP-like signatures in the light curve, of which 11 have stable decaying oscillations. No correlation is found between the QPP period and the stellar temperature, radius, rotation period and surface gravity, suggesting that the QPPs are independent of global stellar parameters. Hence they are likely to be the result of processes occurring in the local environment. There is also no significant correlation between the QPP period and flare energy, however there is evidence that the period scales with the QPP decay time for the Gaussian damping scenario, but not to a significant degree for the exponentially damped case. This same scaling has been observed for MHD oscillations on the Sun, suggesting that they could be the cause of the QPPs in those flares. Scaling laws of the flare energy are also investigated, supporting previous reports of a strong correlation between the flare energy and stellar temperature/radius. A negative correlation between the flare energy and stellar surface gravity is also found.

without any top transparent conductive oxide layer and with Al back metal contact. Such a solar cell has been studied
by two dimensional numerical device simulation using Silvaco TCAD modeling tool. Optimal thickness of the base

reach ~7.8% for 1000 nm thick ZnO absorber.
Factors Lifting Apprenticeship Retention Expectations (FLARe)

Subjects: Educational psychology

description: Almost half of Australian apprentices do not complete their apprenticeship. What motivates them to plan to persist, or drop out? 2,387 apprentices (carpentry, bricklaying, electrical, plumbing) were surveyed four times over 2 years regarding their workplace and trade school experiences and motivations. Workplace interest (positively) and anxiety (negatively) most strongly predicted apprentices’ planned persistence. Interest declined and anxiety increased through training; predicted by career indecision, worksite training and workload. Findings suggest practical levers for employers, teachers and industry groups first, to guide apprenticeship choice and second, positively motivate apprentices in trade school and on-the-job to improve their experience, and retention.

description: This research investigated 3-5-year-old children’s use of digital technologies in the preschool and home settings, and explored their learning possibilities with digital technologies by adopting a posthumanist perspective, specifically Actor-Network Theory (ANT) (Latour, 2005). The findings indicated that young children’s use and learning with technologies is not an autonomous aspect. In fact, it is mediated by number of other agencies. Digital devices were found to play multiple roles for young children such as a source of learning, entertainment and relaxation. It appeared that children’s digital practices do not supplant but complement their traditional activities.

description: Multi-crystalline silicon wafers with micro cracks have been analyzed in a micro crack detection system before and after alkaline and acidic saw damage etching. In addition, a test was performed where saw damage etched wafers with micro cracks were exposed to repeated mechanical stress in a twist test setup.
It was found that the length of micro cracks does not increase in neither alkaline nor acidic saw damage etching, but decreases the shallow parts of the cracks are removed as the surrounding silicon is etched away. If the initial crack is
large enough, the crack can become wider and deeper after etching. No evidence of crack growth due to repeated mechanical stress was found.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 4236-4239
description: Nominal operating cell temperature is used to estimate the cell temperature of a module in its working
environment. NOCT is the cell temperature when irradiance is 800 W/m2, ambient temperature is 20°C and wind
speed is 1 m/s at a module tiltangle 45°. Due to the large and uncontrollable variability of weather conditions
outdoor measurements, such as the NOCT, are affected by major sources of different kinds of uncertainties.
Calculation of this parameter is largely depending on the environment temperature, the direction and speed of the
wind, radiation and back module temperature and the way in which they are measured as long as the way in which the
data are stored, filtered and elaborated. The present job aims to identify the various sources of uncertainties that
broadly and heavily characterize the measurement of the NOCT, to estimate their contribution to the uncertainty and
to calculate the standard and expanded uncertainties as defined by the International vocabulary of basic and general
terms in metrology (VIM), in order to better understand and control the error of the measurement. The procedure can
be applied for outdoor measurements of innovative PV materials.

description: For reliable energy yield predictions an accurate modeling of the PV module behavior is essential. In
this analysis we compare two different possibilities for acquiring the necessary parameters: indoor measurements and
data sheet values. We found that temperature coefficients of power given in data sheets can be used for yield prediction
without introducing higher uncertainties. On the other hand the derivation of model parameters for the modeling
of irradiation dependent efficiency of PV modules based on data sheets is associated with high uncertainties. In a
sample of 50 PV modules only for 15 modules parameters from data sheets could be derived with a sufficient accuracy.

description: We study the general relativistic collapse of neutron star (NS) models in spherical symmetry. Our initially stable models are driven to collapse by the addition of one of two things: an initially in-going velocity profile, or a shell of minimally coupled, massless scalar field that falls onto the star. Tolman-Oppenheimer-Volkoff (TOV) solutions with an initially isentropic, gamma-law equation of state serve as our NS models. The initial values of the velocity profile's amplitude and the star's central density span a parameter space which we have surveyed extensively and which we find provides a rich picture of the possible end states of NS collapse. This parameter space survey elucidates the boundary between Type I and Type II critical behavior in perfect fluids which coincides, on the subcritical side, with the boundary between dispersed and bound end states. For our particular model, initial velocity amplitudes greater than 0.3c are needed to probe the regime where arbitrarily small black holes can form. In addition, we investigate Type I behavior in our system by varying the initial amplitude of the initially imploding scalar field. In this case we find that the Type I critical solutions resemble TOV solutions on the 1-mode unstable branch of equilibrium solutions, and that the critical solutions' frequencies agree well with the fundamental mode frequencies of the unstable equilibria. Additionally, the critical solution's scaling exponent is shown to be well approximated by a linear function of the initial star's central density.

description: In the manufacturing process the surfaces of solar cells are exposed to several kinds of thermal and mechanical loads. These loadings may lead to an increase of micro crack damages and changes of the strength properties of wafers in
the processing lines and of finished solar cells. For the control of the processing and the evaluation of the mechanical performance of wafers quantities related to mechanical strength are needed. To characterize the surface strength of thin wafers (~100 μm) several kinds of bending tests are applied. In the present work the concentric ring test and the ball on ring test (see Figures 1 and 2) are considered particularly with respect to stress configuration and application to the testing of thin wafers.

description: The Ordered Upwind Method (OUM) is used to approximate the viscosity solution of the static Hamilton-Jacobi-Bellman (HJB) with direction-dependent weights on unstructured meshes. The method has been previously shown to provide a solution that converges to the exact solution, but no convergence rate has been theoretically proven. In this paper, it is shown that the solutions produced by the OUM in the boundary value formulation converge at a rate of at least the square root of the largest edge length in the mesh in terms of maximum error. An example with similar order of numerical convergence is provided.
Understanding teacher professional identity through storying learner and teacher experiences

Subjects: Education

description: This autoethnographic study investigates how the researcher's experiences as a second-generation Greek-Australian student and teacher have influenced her professional identity as a teacher in Victorian schools. Underpinning the study is the belief that teachers' personal and professional experiences exert influence long after these events have passed, and that new knowledge is gained by understanding our lived experiences. Insights are provided into bicultural student and teacher identity and the influences on the formation of teachers' professional selves. The findings contribute to knowledge about how bicultural teachers develop their professional identities within their social, cultural, educational and linguistic contexts.

description: In contrast to standard quartz crucibles, which can only be used once, crucibles made of silicon nitride
have the potential of being used several times when multi-crystalline silicon ingot are solidified directionally. In a
previous study [1], it was shown that crucible thermal properties have a significant impact on the heat transfer
conditions during silicon solidification in a small scale furnace. The aim of the present work is to analyse the effect
of the crucible material type on thermally induced stresses and deformations in the ingot and associated material
quality. Transient thermal fields calculated using a global furnace model [2], are used in subsequent mechanical
calculations on the silicon ingot. The stress-strain fields in the ingot are calculated using an elastic formation as well
as including viscoplasticity. Results obtained using silica and silicon nitrides are compared.

description: We present the first comprehensive thermal and rotational analysis of the second most distant trans-Neptunian object (225088) 2007 OR10. We combined optical light curves provided by the Kepler space telescope -- K2 extended mission and thermal infrared data provided by the Herschel Space Observatory. We found that (225088) 2007 OR10 is likely to be larger and darker than derived by earlier studies: we obtained a diameter of d=1535^{+75}_{-225} km which places (225088) 2007 OR10 in the biggest top three trans-Neptunian objects. The corresponding visual geometric albedo is p_V=0.089^{+0.031}_{-0.009}. The light curve analysis revealed a slow rotation rate of P_rot=44.81+/-0.37 h, superseded by a very few objects only. The most likely light-curve solution is double-peaked with a slight asymmetry, however, we cannot safely rule out the possibility of having a rotation period of P_rot=22.40+/-0.18 h which corresponds to a single-peaked solution. Due to the size and slow rotation, the shape of the object should be a MacLaurin ellipsoid, so the light variation should be caused by surface inhomogeneities. Its newly derived larger diameter also implies larger surface gravity and a more likely retention of volatiles -- CH_4, CO and N_2 -- on the surface.

description: Fused Silica SOLAR® crucibles are widely used to melt and crystallise PV silicon in industrial dedicated
furnaces. A coating has to be used to prevent silicon/silica reactions and facilitate release of the ingot from the crucible. In
the present investigation two silicon nitride coatings have been compared. An oxygen doped silicon nitride coating, which
has recently been developed to offer a ready to use (RTU) solution to the multicrystalline silicon ingot producers and a
conventional coating fired at 1100ºC.
Both coatings have been applied to cylindrical crucibles charged with each 12 kg of solar grade silicon (virgin polysilicon
and compensated type). The ingots were produced in a Bridgman type Crystalox pilot scale furnace.
The ingots were evaluated in terms of carrier lifetime (QSSPC) and interstitial oxygen content (FTIR). Solar cells were also
manufactured from two of these ingots (Virgin polysilicon) and characterized in terms of diffusion length and conversion
efficiency.
The ingot grown in the RTU crucible exhibits higher carrier lifetimes than the ingot grown with a conventional coating and
the high hardness of the RTU coating has prevented any sticking points. The cells efficiencies confirm the good quality of the
RTU ingot, the average efficiency is around 16.5% with a standard cell process. These results demonstrate that RTU
SOLAR® crucibles can be suitable for growing silicon ingots.

description: Laser Induced Breakdown Spectroscopy (LIBS) is a tool for the characterization of almost any material. It is a
very precise method, taking less than 10μs and able to make measurements on an area down to 2.10-7m2. The purity of the
material may be measured using LIBS due to its high sensitivity (10-7g/g). Therefore defects or contamination of a given
material may be precisely measured as a function of position on the surface of a given sample. LIBS is a technique which
consists of the high intensity ablation of a surface by a fast highly focused laser and the subsequent analysis of the luminous
emissions from the resulting superheated plasma. The aim of this work is to develop this technique for the analysis of the
distribution of impurities, especially boron, in different grades of silicon.

description: Network alignment, or the task of finding corresponding nodes in different networks, is an important problem formulation in many application domains. We propose CAPER, a multilevel alignment framework that Coarsens the input graphs, Aligns the coarsened graphs, Projects the alignment solution to finer levels and Refines the alignment solution. We show that CAPER can improve upon many different existing network alignment algorithms by enforcing alignment consistency across multiple graph resolutions: nodes matched at finer levels should also be matched at coarser levels. CAPER also accelerates the use of slower network alignment methods, at the modest cost of linear-time coarsening and refinement steps, by allowing them to be run on smaller coarsened versions of the input graphs. Experiments show that CAPER can improve upon diverse network alignment methods by an average of 33% in accuracy and/or an order of magnitude faster in runtime.

description: The phosphatases of regenerating liver are a subfamily of protein tyrosine phosphatases that consist of PRL1, PRL2 and PRL3. The overexpression of PRLs promote cell proliferation, migration and invasion and contribute to tumorigenesis and metastasis to aggravate survival outcome. Although there is increasing interest in understanding the implication of these phosphatases in tumor development, currently, limited knowledge is available about their mechanism of action and the efficacy of PRL inhibition in in vivo tumor models, the tumor extrinsic role of PRLs that allow them to impact tumor development, as well as in vivo physiological function of PRLs that could implicate them in diseases other than cancer. The work presented here aims to address these limitations.

description: Silicon wafers still represent a significant part of the costs of current solar modules. Passivated
Emitter and Rear Cells (PERC) are a very promising technology in comparison to conventional cells. In this study
PERC point like contacts at the back surface of p-type CZ silicon wafers realized with an industrial feasible
technique are investigated. Since the formation of the Back Surface Field (BSF) is a critical step for the performance
of solar cells, cross sections of the local contacts have been analyzed at the Scanning Electron Microscope (SEM). In
order to investigate how to control the formation of the BSF, two different pastes consisting of pure aluminium
particles were screen printed and different thermal profiles were applied. As a function of the width of the contacts,
three major profiles can be observed: triangular, trapezoidal and with rounded edges at the sides. An explanation of
the origin of these profiles is offered here. Concerning the results, one of the pastes allows achieving thicker and
more homogenous BSF layers for widths of the contacts in the range of 120 to 190 Bm. This investigation shows that
the present optical characterization is helpful to characterize the thickness of the BSF and, hence, its synergic use
with electrical investigations can bring about enhancements in the performance of the cells.

description: This study examines the phenomenon of women’s academic leadership in Mongolia, where women remain considerably under-represented in senior leadership positions at the more prestigious, public universities, but are equally represented as leaders at the less prestigious, private universities. The study aims to investigate this phenomenon, employing feminist qualitative methodology and Bourdieu’s conceptual tools—field, habitus, and capital—as part of a feminist ontology and transnational feminist epistemology. The study makes contributions to feminist research and theorising of women and academic leadership in the context of a postsocialist East Asian country—an area that remains considerably under-explored.

description: The Low Resolution Spectrometer of the MIRI, which forms part of the imager module, will provide R~100 long-slit and slitless spectroscopy from 5 to 12 micron. The design is optimised for observations of compact sources, such as exoplanet host stars. We provide here an overview of the design of the LRS, and its performance as measured during extensive test campaigns, examining in particular the delivered image quality, dispersion, and resolving power, as well as spectrophotometric performance, flatfield accuracy and the effects of fringing. We describe the operational concept of the slitless mode, which is optimally suited to transit spectroscopy of exoplanet atmospheres. The LRS mode of the MIRI was found to perform consistently with its requirements and goals.

description: As continuation of analysis of principles for plasmonic photovoltaics, theoretical calculation of light
transmittance enhancement into semiconductor base of solar cell due to light trapping via excitation of local (surface)
plasmons and surface plasmon polaritons in periodic metal nanowires array has been considered. Calculations have
been performed for rectangular metal wires at increasing of metal filling factor from 1/8 to 6/8 and results are
compared with flat continuous film with the same mass thickness. The differential formalism method using the
covariant form of Maxwell’s equations in curvilinear coordinate system has been used. The transformation of local
(surface) plasmons into surface plasmon polaritons with f-factor increase at the increase of wire width is considered.
The averaged photocurrent of solar cell with wire periodic system increases in comparison with a flat gold film on
GaAs or Si substrate for example, on 40-60% for Si into surrounding medium with n = 1.45 and gold wire height
50 nm, period 550 nm. Photocurrent generation in both far-field (wave) and near-field zones peculiarities in
transmittance/reflectance spectra of emitter thin layer is discussed.

description: This qualitative study examined the beliefs and practices of three excellent secondary science teachers. Semi-structured interviews were conducted with the teachers about their background, experiences and beliefs about teaching and learning science in the middle years (years 7-10). Lessons were observed and students interviewed to understand their perspectives on their teacher’s practice to establish factors involved in the development of their excellence. The results demonstrate that factors involved in the development of excellence are complex and requires consideration of the links between context, personal attributes and how teachers’ professional knowledge is developed and applied in practice.

description: In this paper we discuss the potential for improving thin film solar cell efficiencies by introducing index
matching layers at the glass/TCO and TCO/absorber interface. The additional layers can, providing the right
optical properties, act as anti-reflective layers. We discuss optimum thickness values of such layers and compare
hypothetical ideal materials with real modified oxide materials, grown by spray pyrolysis. In addition we discuss
morphological concepts to reduce internal reflections, namely rough TCO/absorber interfaces. The potential efficiency
improvement is calculated from the increase in the transmission into the absorber. As additional layers increase
the production cost, we also give estimates for the cost structure of the thin film cell at which the increase in
efficiency outweighs the increase in cost, thus reducing the cost/Wp ratio.

description: Human driving behavior and road conditions significantly affect fuel consumption and greenhouse gas (GHG) emissions of a vehicle. In particular, signalized intersections, roundabouts, and road-geometry characteristics, such as, hilly roads and horizontal curves are the major sources of bottlenecks. This thesis develops intelligent and advanced vehicle control systems for cooperative ecological (eco) driving in these road scenarios. The proposed vehicle control systems generate optimal speed profiles for fuel-efficient driving. The results show significant performance improvement in fuel economy, GHG emissions, and travel time compared to the traditional driving system, while ensuring driving safety.

description: High performance coatings made with TiO2 , SiO2, SiN, and ZnS layers are investigated. TiO2 coatings
made by Ti evaporation or sputtering followed by oxidation in air exhibit refractive indices greater than 2.5 to 3 in the
visible. The addition of a SiO2 or low-K layer (index around 1.38) reduces the minimum reflection below 0.2% in the
visible range and less than 5% averaged over the solar spectrum. Double layer coatings have also been made by spin-on
solutions and low temperature annealing (<500°C). The EQE (external quantum efficiency) of Si cells made with these
coatings are nearly flat from the Si bandgap to the UV. For the AM1.5 environment, the very low reflectance throughout the
visible and near-IR has resulted in untextured Si cells with over 40 mA/cm2 photocurrents. The paper presents
simulations of single and double layer coatings on smooth Si and GaAs surfaces, with and without cover glasses as in
finished cell modules. Calculations are also made for HIT cells (Si with amorphous Si and TCO layers) and CIGS with
ZnO, ITO, and CdS layers. The purpose of these simulations is to act as a guide for minimizing the reflectance loss in
different kinds of cells.

description: We present multi-frequency Very Long Baseline Array (VLBA) follow-up observations of VLBA Imaging and Polarimetry Survey sources identified as likely compact symmetric objects (CSOs) or super-massive binary black holes (SBBHs). We also present new spectroscopic redshifts for 11 sources observed with the Hobby-Eberly Telescope. While no new SBBHs can be confirmed from these observations, we have identified 24 CSOs in the sample, 15 of which are newly designated, and refuted 52 candidates leaving 33 unconfirmed candidates. This is the first large uniform sample of CSOs which can be used to elicit some of the general properties of these sources, including morphological evolution and environmental interaction. We have detected polarised emission from two of these CSOs the properties of which are consistent with Active Galactic Nuclei unification schemes.

description: Current versus voltage (IV) characteristics of a solar array and its modules is critical to understanding their
behavior as a source and for the design of moduel electronics for maximum power tracking and extraction. Our work is
setup in an urban environment, where the conditions are not necessarily optimal all the time, since our array is located in
the middle of commercial buildings and next to an elevated high density traffic network. This makes our array susceptible
to large amounts of energy losses such as different irradiance conditions due to urban pollution, dust, dirt from rubber
tires from vehicles in the highway, shading and low angles of illumination at a seasonal level. Because of these various
and unpredictable field conditions, this necessitates the need to take the measurements at a high fast sweep rate over the
entire range of the module and the array. Commercial systems to sweep and load are available, however with limited
customization. Also, with the cost per watt approximately at $1 for a commercial loader, this price to build this setup
quickly runs to be very expensive. An alternate setup to sweep the IV curves across all modules and the entire array
using one loader using high power MOSFETs as high speed switches as well as determination of MPPT is presented in
this paper.

description: While smart mobile health apps that adapt to users' progressive individual needs are proliferating, many of them struggle to fulfill their promises due to an inferior user experience. Understanding the concerns of real-world users related to those apps, and their smart components in particular, could help advance the app design to attract and retain users. In this paper, we target this issue through a preliminary thematic analysis of 120 user reviews of six smart health apps. We found that accuracy, customizability, and convenience of data input are primary concerns raised in real-world user reviews. Many concerns on the smart components are related to the trust issue of the users towards the apps. However, several important aspects such as privacy and fairness were rarely discussed in the reviews. Overall, our study provides insights that can inspire further investigations to support the design of smart mobile health apps.

description: The classification of solar cells and the comparison of cells from different origins is typically based on
the cell efficiencies. As a consequence, the efficiency and the related parameters of short circuit current, open-circuit
voltage and fill factor need to be measured precisely. This requires an IV setup with a small bias error and a good
stability over time. In this study, an IV setup is gradually improved by the stepwise implementation of several
adaptations. The effect of these improvements on the measured solar cell parameters is tracked and after completion
of the improvement process, the measured parameters are compared to the values measured at a calibration lab to
quantify the bias error of the final setup.
