Towards the Valorization of Phosphate Wastes in bituminous materials
Creators: name: AMRANI, Mustapha
Publisher: name: Academic Journal of Civil Engineering
Year: 2020

description: The phosphate production process generates millions of tons of wastes annually in Morocco. These mine tailings could have negative impacts that can be observed on the surrounding environment. Therefore, innovative strategies should be proposed to valorize the solid wastes. This paper investigates a new approach of phosphate waste valorization in producing asphalt mixtures which can be a cost-effective and eco-friendly solution for managing these wastes. The main goal of the presented study is to examine the feasibility of using three phosphate wastes for fabrication of bituminous materials and to discover the better waste to be added in asphalt mixtures. Many solid wastes are selected to be used as minerals fillers. it is showed that the viscous flow behavior of the asphalt binder containing phosphogypsum and fly ash wastes is substantially improved in compression of that of asphalt binder with phosphate sludge filler. In addition, it was observed that phosphogypsum waste can enhance the mechanical properties of asphalt binder as well as its performance against rutting in comparison to the others wastes.

description: Les structures composites sandwich « Steel-Concrete-Steel » répondent à de nombreux besoins. Leur forte résistance, rigidité, durabilité, étanchéité et leur modularité en font un choix de structure de plus en plus concurrentiel. Cette étude porte sur le comportement local de cisaillement de la connexion avec la modélisation d’un essai push-out. Cet essai normalisé permet de caractériser la résistance à la rupture ainsi que la loi effort-glissement de la connexion, paramètres importants pour la conception de structures composites. Une stratégie de simulation avec des éléments finis 3D est présentée. Les interactions entre les différents composants sont correctement reproduites. Cependant, les résultats montrent une forte dépendance au maillage, nécessitant la mise en place d’une procédure de régularisation, effectuée par modification des paramètres en compression en fonction de la taille des éléments. Avec cette régularisation, les résultats numériques, peu dépendants du maillage, sont proches des résultats expérimentaux.

Hamiltonian Superfield Formalism with N Supercharges

Subjects: subject: High Energy Physics - Theory (hep-th)

description: An action principle that applies uniformly to any number N of supercharges is proposed. We perform the reduction to the N=0 partition function by integrating out superpartner fields. As a new feature for theories of extended supersymmetry, the canonical Pfaffian measure factor is a result of a Gaussian integration over a superpartner. This is mediated through an explicit choice of direction n^a in the θ-space, which the physical sector does not depend on. Also, we re-interpret the metric g^{ab} in the Susy algebra [D^a,D^b] = g^{ab}\partial_t as a symplectic structure on the fermionic θ-space. This leads to a superfield formulation with a general covariant θ-space sector.

On the Importance of Searching for Oscillations of the Jovian Inner Radiation Belt with a Quasi-Period of 40 Minutes

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: Experiments aboard the Ulysses spacecraft discovered quasi-periodic bursts of relativistic electrons and of radio emissions with ~40-minute period(QP-40) from the south pole of Jupiter in February 1992. Such polar QP-40 burst activities were found to correlate well with arrivals of high-speed solar winds at Jupiter. We advance the physical scenario that the inner radiation belt(IRB) within ~2-3 Jupiter's radius, where ralativistic electrons are known to be trapped via synchrotron emissions, can execute global QP-40 magnetoinertial oscillations excited by arrivals of high-speed solar winds. Modulated by such QP-40 IRB oscillations, relativistic electrons trapped in the IRB may escape from the magnetic circumpolar regions during a certain phase of each 40-min period to form circumpolar QP-40 electron bursts. Highly beamed synchrotron emissions from such QP-40 burst electrons with small pitch angles relative to Jovian magnetic field at ~30-40 Jupiter radius give rise to QP-40 radio bursts with typical frequencies <0.2MHz. We predict that the synchrotron brightness of the IRB should vary on QP-40 timescales upon arrivals of high-speed solar winds with estimated magnitudes larger than 0.1Jy, detectable by ground-based radio telescopes. Using the real-time solar wind data from the spacecraft ACE, we show here that shch QP-40 pulsations of Jupiter's polar X-ray hot spot did in fact coincide with the arrival of high-speed solar wind at Jupiter.

description: We address an apparent conflict between the traditional canonical quantization framework of quantum theory and the spatially restricted quantum dynamics, when the translation invariance of the otherwise free quantum system is broken by boundary conditions. By invoking an exemplary case of a particle in an infinite well, we analyze spectral problems for related, confined and global, observables. In particular, we show how one can make sense of various operators pertaining to trapped particles by not ignoring the rest of the real line (e.g., that space which is never occupied by the particle in question).

description: Biomolecular processes are typically modeled using chemical reaction networks coupled to infinitely large chemical reservoirs. A difference in chemical potential between these reservoirs can drive the system into a non-equilibrium steady state (NESS). In reality, these processes take place in finite systems containing a finite number of molecules. In such systems, a NESS can be reached with the help of an externally driven pump for which we introduce a simple model. Crucial parameters are the pumping rate and the finite size of the chemical reservoir. We apply this model to a simple biochemical oscillator, the Brusselator, and quantify the performance using the number of coherent oscillations. As a surprising result, we find that higher precision can be achieved with finite-size reservoirs even though the corresponding current fluctuations are larger than in the ideal infinite case.

description: The detection of objects considering a 6DoF pose is a common requirement to build virtual and augmented reality applications. It is usually a complex task which requires real-time processing and high precision results for adequate user experience. Recently, different deep learning techniques have been proposed to detect objects in 6DoF in RGB images. However, they rely on high complexity networks, requiring a computational power that prevents them from working on mobile devices. In this paper, we propose an approach to reduce the complexity of 6DoF detection networks while maintaining accuracy. We used Knowledge Distillation to teach portables Convolutional Neural Networks (CNN) to learn from a real-time 6DoF detection CNN. The proposed method allows real-time applications using only RGB images while decreasing the hardware requirements. We used the LINEMOD dataset to evaluate the proposed method, and the experimental results show that the proposed method reduces the memory requirement by almost 99\% in comparison to the original architecture with the cost of reducing half the accuracy in one of the metrics.

title: Expression chemokines and G protein-coupled receptors in myeloid cells
Creators: name: Skelton, Lisa
Publisher: name: The Open University
Year: 2003

description: The myeloid cell lineage represents a diverse collection of cell types arising from a common progenitor. Two extreme phenotypes of this lineage belong to the osteoclast and the dendritic cell. This thesis evaluates differential expression of a discrete selection of genes in these two cell types, as they differentiate from their monocyte precursor, utilising well-characterized in vitro differentiation systems and microarray gene technology.

 A custom made microarray, including all known chemokine and chemokine receptor genes and related G protein-coupled seven transmembrane (7TM) receptors and ligands, was employed. Expression of transcripts encoding chemokine and chemokine receptors by dendritic cells, and a study of protein expression / production by these cells, served as validation for the microarray gene technology used. In particular, the array data revealed two interesting findings, which were investigated further.

 GPR105 gene expression by immature DCs was confirmed by Northern blot analysis. UDP-glucose, an agonist for GPR105, induced calcium responses uniquely in immature DCs, correlating with the gene expression data. This response demonstrated partial sensitivity to pertussis toxin, implicating a 7TM receptor linked to a Gia containing G protein, such as GPR105. Moreover, immature DCs from some donors treated with UDP-glucose exhibited an increase in expression of the co-stimulatory molecule CD86, which correlated with the intensity of an UDP-glucose-induced calcium flux, suggesting a role for this GPCR and its agonist in DC activation.

 Production of the angiogenic chemokine CXCL5 by in vitro-derived osteoclast cultures was confirmed by ELISA and attributed to multinuclear cells by immunocytochemistry. Supernatants from osteoclast cultures induced chemotaxis of neutrophils, which was decreased in the presence of an antibody to CXCL5. A role for osteoclast produced CXCL5 in angiogenesis is discussed.
A Life Cycle Assessment of the Mathematics Building

Publisher: name: The University of British Columbia
Year: 2012

description: A Life Cycle Assessment for the Mathematics Building at the University of British Columbia (UBC) has been completed in conjunction with 29 other buildings at the UBC campus. The ultimate goal is to have a database of LCA’s for all buildings at UBC enabling comparisons to be made between buildings with different structure types, functions and over time. Only the structure and envelope are included in the building model and environmental impacts are only considered for the manufacture and construction phases. The Mathematics building, built in 1925, is a 2 story wood frame building and is comprised of 18 classrooms, 21 offices and a 250 person capacity lecture hall. 2 software programs - The Athena Sustainable Material Institute’s Environmental Impact Estimator and OnCentre’s OnScreen Takeoff - are used to assist with the material takeoff for the building. The EIE is used to assess the environmental impacts of building materials. The Math Building was found to have approximately 20 to 40% of the impacts per square foot that the average UBC building produces in terms of energy consumption, resource use, eutrophication potential, acidification potential, smog potential, human health effects potential and global warming potential. The high proportion of wood caused the ozone depletion potential to be 150% the average UBC building. Sensitivity analysis determined that the model is most sensitive to concrete for most impact categories and to wood for ozone depletion potential. Using a simple energy model, it was determined that if insulation is added to the walls and roof of the as built structure, the energy payback period is less than 2 weeks and the operating energy demand is reduced by 2,500GJ/year.[Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

For example, we show that if $n\ge m-1$ then $$\sum_{i=0}^{\lfloor(m-1)/2\rfloor}(-1)^i\binom{m-1-i}i [n-2i,r-i]_m=2^{n-m+1}.$$ We also apply such results to investigate Bernoulli and Euler polynomials. Our approach depends heavily on an identity established by the author [Integers 2(2002)].

description: We present a configuration interaction method optimized for Fock-Darwin states of two-dimensional quantum dots with an axially symmetric, parabolic confinement potential subject to a perpendicular magnetic field. The optimization explicitly accounts for geometrical and dynamical symmetries of the Fock-Darwin single-particle states and for many-particle symmetries associated with the center-of-mass motion and with the total spin. This results in a basis set of reduced size and improved accuracy. The numerical results compare well with the quantum Monte Carlo and stochastic variational methods. The method is illustrated by the evolution of a strongly correlated few-electron droplet in a magnetic field in the regime of the fractional quantum Hall effect.

description: One of the reasons often cited for underdevelopment of African cities and regions is low application of smart technology to improve means of production. This often led to inefficiency which is ultimately reflected in space. This paper investigated the level of ICT usage among small scale manufacturing enterprises in Ondo State. The study also investigated intra-regional variations in use of smart technologies in the industrial subsector and compared same across the three regions of the state. A sample of 352 enterprises was taken from three senatorial regions and nine settlements which were purposively sampled and interviewed using questionnaire. The production and operational system of these firms were observed. The data collected were analysed using descriptive and inferential methods. The study established that proportion of ICT users concentrated more in Ondo Central 45.7% than Ondo south (28.7%) and Ondo north (25.6%). It was also discovered that formal small scale enterprises made more use of ICT products, compared with those in the informal sector. Moreover ICT use among enterprises were urban biased as 91.2% of enterprises in this category were located in major towns of Akure, Okitipupa and Ikare, 8.1% in minor towns of Obaile, Ode Aye and Ugbe, with villages of Aponmu Iboropa and Ikoya being relatively insignificant (0.8%). The study established that enterprises that made use of smart technologies tend to be more efficient in terms of production and marketing especially in identification of new markets, networking, subcontracting, security and other linkage benefits. Also, regional industrial development entails not only quantitative growth of industries, but an industry that embrace a new opportunities in innovation, and technology especially in management, record keeping, production, decision making etc.

description: The increased use of algorithmic predictions in sensitive domains has been accompanied by both enthusiasm and concern. To understand the opportunities and risks of these technologies, it is key to study how experts alter their decisions when using such tools. In this paper, we study the adoption of an algorithmic tool used to assist child maltreatment hotline screening decisions. We focus on the question: Are humans capable of identifying cases in which the machine is wrong, and of overriding those recommendations? We first show that humans do alter their behavior when the tool is deployed. Then, we show that humans are less likely to adhere to the machine's recommendation when the score displayed is an incorrect estimate of risk, even when overriding the recommendation requires supervisory approval. These results highlight the risks of full automation and the importance of designing decision pipelines that provide humans with autonomy.

description: This paper aims to review the concept of resource curse, to summarize key points from existing literature and apply them on four selected countries at the beginning of the new millennium. The practical part investigates several hypotheses established by comparing research papers on impact of natural resources on the example of two developing countries (Nigeria and Botswana) and two developed countries (Canada and Norway). Specifically, the validity of the Prebisch-Singer hypothesis, Dutch disease symptoms and several hypotheses about a negative impact on political institutions have been verified. The results confirm the Prebisch-Singer hypothesis for selected commodities in the long term and some of the symptoms of Dutch disease in period 2000–2016 in the selected countries. Hypotheses about the impact on the political institutions have not been confirmed. The prices of commodities were identified as a key transmission channel of resource curse in the short run.

description: The stringent experimental bound on $μ\rightarrow e γ$ is compatible with a simultaneous and sizable new physics contribution to the electron and muon anomalous magnetic moments $(g-2)_\ell$ ($\ell=e,\,μ$), only if we assume a non-trivial flavor structure of the dipole operator coefficients. We propose a mechanism in which the realization of the $(g-2)_\ell$ correction is manifestly related to the mass generation through a flavor symmetry. A radiative flavon correction to the fermion mass gives a contribution to the anomalous magnetic moment. In this framework, we introduce a chiral enhancement from a non-trivial $\mathcal{O}(1)$ quartic coupling of the scalar potential. We show that the muon and electron anomalies can be simultaneously explained in a vast region of the parameter space with predicted vector-like mediators of masses as large as $M_χ\in [0.6,2.5]$~TeV.

description: Agrilus dubiosus sp. nov.
 (Fig. 5)
 Etimologia: latim, dubiosus = duvidoso (ver notas comparativas).
Comprimento 6,6 mm. Fronte verde, microesculturada e glabra. Clípeo separado da fronte por uma fina carena transversal. Antenas verdes, denteadas a partir do antenômero IV. Olhos grandes, globosos, ocupam 4/5 da cabeça. Pronoto com carena pré-umeral inteira, unida à carena marginal antes do meio do pronoto. No lado interno da parte anterior da carena pré-umeral, uma linha de pubescência amarela, como as do élitro. Carenas marginais divididas também na base, com a submarginal levemente curva para baixo na parte posterior. Mentoneira com margem anterior não sinuada e pouco convexa. Processo prosternal com bordas laterais paralelas, espessas e em relevo. Laterotegitos com uma mancha pubescente no segmento basal. Lado ventral do corpo preto, com pubescência branca nos metepiternos e nas metacoxas. A mesma pubescência, mas no formato de manchas nos lados dos urosternitos II, III, e IV. O urosternito I apresenta linha pubescente longitudinal mediana com pouco mais do que a metade do mesmo. Pernas brônzeo-esverdeadas. Unhas anteriores bífidas. Metatarso mais longo que a metatíbia. Artículo I longo quanto a soma dos três seguintes (I = II + III + IV). Edeago fusiforme, com lobo mediano acuminado (Fig. 19).
 Descrição dos parátipos: Comprimento 5,9-6,3 mm. Dois exemplares possuem élitros pretos ao invés de verde-escuro.
 Material tipo: Holótipo ♂: BRASIL, Amazonas, Itacoatiara, I.1963, Dirings leg. (MZUSP). Parátipo 7 ♂♂: idem, (MZUSP & MCCI).
 Discussão: A. laetabilis Kerremans, 1897, descrito de Minas Gerais, apresenta as mesmas características morfológicas que A. dubiosus e tivemos dúvida em atribuír os exemplares citados acima à uma nova espécie.
 A dúvida aumenta pelo fato de A. laetabilis ter sido descrito em base à apenas um exemplar de sexo feminino, enquanto a série típica de A. dubiosus é composta apenas por machos, por isso as pequenas diferenças podem ser atribuídas a dimorfismo sexual. Todavia, a nítida diferenciação zoogeográfica (Itaituba encontra-se no coração da Amazônia) levou-nos à descrição, na esperança de que seja encontrado um macho da espécie do Kerremans e a comparação entre os respectivos edeagos possa resolver o problema definitivamente.
Os principais caracteres de diferenciação podem ser resumidos como segue:

description: Maize is the third most important cereal crop in India after rice and wheat. The paper has highlighted the adoption pattern of improved maize technology in the traditional maize growing states, viz. Bihar, Madhya Pradesh, Punjab, Rajasthan and Uttar Pradesh, along with its impact on farm earning and trade prospects. Although, the adoption of modern technology by farmers in this region has been low, the impact of these technologies has been found significant. The yield of hybrid cultivars is more than 4 tonne/ha compared to less than 2.5 tonne/ ha from the traditional cultivars during the kharif season. Similarly, during the rabi season, yield from hybrids has been about 6 tonne/ha and from composites, 4 tonne/ha. The unit cost of production has declined considerably, adding to the farm profits, and turning maize more profitable in comparison to its competing crops. On the trade front, the major maize importers in the world are the Asian counties which source it from the distant countries like the USA and Argentina. India being located at a shorter distance can offer transport-cost advantage to these countries. It has been suggested that the adoption of improved technologies and improvement in infrastructure and processing could help farmers realize the benefits of trade liberalization.

description: Quantum measurement is universal for quantum computation. Two models for performing measurement-based quantum computation exist: the one-way quantum computer was introduced by Briegel and Raussendorf, and quantum computation via projective measurements only by Nielsen. The more recent development of this second model is based on state transfers instead of teleportation. From this development, a finite but approximate quantum universal family of observables is exhibited, which includes only one two-qubit observable, while others are one-qubit observables. In this article, an infinite but exact quantum universal family of observables is proposed, including also only one two-qubit observable. The rest of the paper is dedicated to compare these two models of measurement-based quantum computation, i.e. one-way quantum computation and quantum computation via projective measurements only. From this comparison, which was initiated by Cirac and Verstraete, closer and more natural connections appear between these two models. These close connections lead to a unified view of measurement-based quantum computation.

description: Inside living cells are complex mixtures of thousands of components. It is hopeless to try to characterise all the individual interactions in these mixtures. Thus, we develop a statistical approach to approximating them, and examine the conditions under which the mixtures phase separate. The approach approximates the matrix of second virial coefficients of the mixture by a random matrix, and determines the stability of the mixture from the spectrum of such random matrices.

Life cycle analysis : Fred Kaiser Building
Creators: name: Liao, Dongqi
Publisher: name: The University of British Columbia
Year: 2012

description: In this report, Fred Kaiser Building was analyzed for life cycle assessment. This analysis includes quantity takeoff and data input by using OnScreen Takeoff and Athena Impact Estimator. TheOnScreen Takeoff Software creates a material list which includes the material type and quantities for data inputs in Athena Impact Estimator. The Impact Estimator uses the TRACI impact database to quantify the environmental impacts of the building assemblies. The results of impact estimator include Bill of Materials and summary measures by life cycle stage and assembly group. The summary measures by life cycle stage showed eight categories of environmental impacts which are associated with the manufacturing stage of the building. A sensitivity analysis was base on the five anticipated materials to investigate the relative impacts of each material overall environmental impact. It was determined that the most influential component out of the five chosen was the concrete with 30 MPa strength and average flyash. In addition, an analysis was conducted to determine the amount of materials needed to improve the current buildings energy performance to UBC’s Residential Environmental Assessment Program. Operating energy data was obtained from the UBC building services department and a spreadsheet template was used to determine the improvement of operating energy given material upgrades. It was determined that it will take approximately 36 months to recover the energy input for adding insulation materials from energy saving.

description: We report a Raman scattering study of low-temperature, pressure-induced melting of the CDW phase of 1T-TiSe2. Our Raman scattering measurements reveal that the collapse of the CDW state occurs in three stages: (i) For P<5 kbar, the pressure dependence of the CDW amplitude mode energies and intensities are indicative of a ``crystalline'' CDW regime; (ii) for 5 < P < 25 kbar, there is a decrease in the CDW amplitude mode energies and intensities with increasing pressure that suggests a regime in which the CDW softens, and may decouple from the lattice; and (iii) for P>25 kbar, the absence of amplitude modes reveals a melted CDW regime.

description: The observation of long range ridge-like structure in the near-side region of the two particle $Δη-Δϕ$ correlations as measured by LHC experiments in high multiplicity p$-$p collisions indicated towards the presence of collective effects which are similar to that observed in p$-$A(nucleon-nucleus) and A$-$A (nucleus-nucleus) collisions. The two particle correlation between the charged particles in $Δη-Δϕ$ for p$-$p collisions at $\sqrt{s}$ = 7 TeV and 13 TeV is studied using Pythia 8 event generator within the framework of final-state partonic color reconnection effects as well as the microscopic rope hadronization model. The rope hadronization relies on the formation of ropes due to overlapping of strings in high multiplicity events followed by string shoving. A near side ridge-like structure which is qualitatively similar to the observed ridge in data was observed for high-multiplicity events when the mechanism of rope hadronization (with shoving) was enabled.

Magnetic and orbital ordering of RuO2 planes in RuSr2(Eu,Gd)Cu2O8

description: We start from an effective Hamiltonian for Ru ions in a square lattice, which includes the on-site interactions between t_2g orbitals derived from Coulomb repulsion, and a tetragonal crystal-field splitting. Using perturbation theory in the hopping terms, we derive effective Hamiltonians to describe the RuO2 planes of RuSr2(Eu,Gd)Cu2O8. For undoped planes (formal valence Ru{+5}), depending on the parameters we find three possible orderings of spin and orbitals, and construct a phase diagram. This allows to put constraints on the parameters based on experimental data. When electron doping consistent with the hole doping of the superconducting RuO2 planes is included, we obtain (for reasonable parameters) a double-exchange model with infinite antiferromagnetic coupling between itinerant electrons and localized spins. This model is equivalent to one used before [H. Aliaga and A. A. Aligia, Physica B 320, 34 (2002)] which consistently explains the seemingly contradictory magnetic properties of RuSr2(Eu,Gd)Cu2O8.

description: The present study conducted in Karaikal region of the Union Territory of Pondicherry during 2002-03 has revealed that paddy production through the direct-sown method is more profitable as compared to the traditional transplanting method. Direct-sown method reduces the requirements of plant nutrients, irrigation and labour and thereby costs of production. The productivity, however, has been found less with the direct sowing than the traditional sowing. But, due to reduction in production costs, farmers could realize higher net income from the adoption of direct-sown method. The technical efficiency is also less on direct seeded farms, indicating a need for improving farmers' skills in the application of new technology.

description: Specific heat of the layered NaxCoO2 (x=0.65, 0.70 and 0.75) oxides has been measured in the temperature range of 3-360 K and magnetic field of 0 and 9 T. The analysis of data, assuming the combined effect of inter-layer superexchange and the phase separation into mesoscopic magnetic domains with localized spins embedded in a matrix with itinerant electronic character, suggests that the dominant contribution to the specific heat in the region of short-range ordering is mediated by quasi-2D antiferromagnetic clusters, perpendicular to the CoO2 layers.

description: The study-assesses the impact of Boro rice on farmers' income and employment using the farm level data. The yields of Boro rice are higher than the kharifrice. Though its cost of cultivation is higher, the net returns over cost A are positive. Cultivation of Boro rice has been found more profitable compared to other crops grown during this season in this area. Small farmers put a larger area to Boro rice cultivation and they are likely to be benefited the most from its expansion in the flood-prone areas. The impact of Boro rice cultivation on employment has also been found significant because a majority of the farm labour remains unemployed or under-employed due to lack of employment opportunities on and off the farm. However, the farmers have been noted to be risk averse due to high cost of production and terminal drought. Introduction of short-duration and drought-resistant varieties along with provision of short-term credit can help the expansion of Boro rice cultivation in the flood-prone district of Madhubani in Bihar.
Lambda(1520) and Sigma(1385) resonance production in Au+Au and p+p collisions at RHIC (sqrt{s_NN}=200 GeV)

description: The production of Lambda(1520) in p+p and Au+Au collisions provided by the RHIC at sqrt{s_NN}=200 GeV are investigated using the STAR detector. A preliminary Sigma(1385) signal is also shown. Models predict that a late rescattering phase in ultra-relativistic heavy ion collisions should lower the measured yields of these resonances. This reduction is presently confirmed through the Lambda(1520)/Lambda ratio which has been calculated for p+p collisions and compared with Au+Au collisions.
