description: Ni(OH)2 nanocrystals grown on graphene sheets with various degrees of oxidation are investigated as electrochemical pseudocapacitor materials for potential energy storage applications. Single-crystalline Ni(OH)2 hexagonal nanoplates directly grown on lightly-oxidized, electrically-conducting graphene sheets (GS) exhibit a high specific capacitance of ~1335F/g at a charge and discharge current density of 2.8A/g and ~953F/g at 45.7A/g with excellent cycling ability. The high specific capacitance and remarkable rate capability are promising for applications in supercapacitors with both high energy and power densities. Simple physical mixture of pre-synthesized Ni(OH)2 nanoplates and graphene sheets show lower specific capacitance, highlighting the importance of direct growth of nanomaterials on graphene to impart intimate interactions and efficient charge transport between the active nanomaterials and the conducting graphene network. Single-crystalline Ni(OH)2 nanoplates directly grown on graphene sheets also significantly outperform small Ni(OH)2 nanoparticles grown on heavily-oxidized, electrically-insulating graphite oxide (GO), suggesting that the electrochemical performance of these composites are dependent on the quality of graphene substrates and the morphology and crystallinity of the nanomaterials grown on top. These results suggest the importance of rational design and synthesis of graphene-based nanocomposite materials for high-performance energy applications.

description: Context: Several studies have so far placed useful constraints on planetary atmospheric properties using transmission spectrsocopy, and in the case of HD209458b even the radial velocity of the planet during the transit event has been reconstructed opening a new range of possibilities. AIMS. In this contribution we highlight the importance to account for the orbital eccentricity and longitude of periastron of the planetary orbit to accurately interpret the measured planetary radial velocity during the transit. Methods: We calculate the radial velocity of a transiting planet in an eccentric orbit. Given the larger orbital speed of planets with respect to their stellar companions even small eccentricities can result in detectable blue or redshift radial velocity offsets during the transit with respect to the systemic velocity, the exact value depending also on the longitude of the periastron of the planetary orbit. For an hot-jupiter planet, an eccentricity of only e=0.01 can produce a radial velocity offset of the order of the km/s. Conclusions: We propose an alternative interpretation of the recently claimed radial velocity blueshift (~2 km/s) of the planetary spectral lines of HD209458b which implies that the orbit of this system is not exactly circular. In this case, the longitude of the periastron of the stellar orbit is most likely confined in the first quadrant (and that one of the planet in the third quadrant). We highlight that transmission spectroscopy allows not only to study the compositional properties of planetary atmospheres, but also to refine their orbital parameters and that any conclusion regarding the presence of windflows on planetary surfaces coming from transmission spectroscopy measurements requires precise known orbital parameters from RV.

description: The sulphated glycoprotein SSG 185 is the monomeric precursor of a highly aggregated structural element in the extracellular matrix of the multicellular green alga Volvox carteri. A phosphodiester of arabinose was isolated from a saccharide fragment of SSG 185. The structure of this phosphodiester was investigated by methylation analysis, 13C-NMR, photometric methods and enzymatic assays and identified as D-Araiota-5-phospho-5-D-Araiota. The function of this phosphodiester bridge as a crosslink of different carbohydrate chains in SSG 185 is discussed.
Biomass torrefaction in slot-rectangular spouted beds
Creators: name: Wang, Ziliang
Publisher: name: University of British Columbia
Year: 2017

description: Biomass, a nearly carbon-neutral energy resource, can reduce greenhouse gas emission and replace fossil fuels, but it is characterized by heterogeneity, high moisture content, low bulk density, low calorific value, pliability and hygroscopic nature, all of which challenge its utilization. Torrefaction, a thermal pretreatment method, is capable of modifying the physical-chemical properties of biomass and enhancing its calorific value. Slot-rectangular spouted beds (SRSBs) can effectively handle biomass particles and offer a promising way to overcome the scale-up challenge of conventional spouted beds. This study explored the potential application of SRSBs to biomass torrefaction. Solids mixing in a dual-compartment slot-rectangular spouted bed (DSRSB) was first studied to address the scale-up issue, while also providing fundamental information needed for the design and operation of a DSRSB reactor. SRSB and DSRSB reactors were developed for torrefying sawdust with the semi-batch operation. Hydrodynamics of SRSB and DSRSB, torrefaction performance, torrefied product properties and torrefied product pyrolysis were subsequently investigated. Temperature, biomass feed rate, sawdust particle size and oxygen concentration influenced torrefaction performance and torrefied product properties. Temperature was found to be the most important factor. Biomass torrefaction performed better in the DSRSB than in the SRSB. Higher temperature, lower biomass feed rate, larger sawdust particle size and greater oxygen concentration all led to increased weight loss and decreased energy yield of sawdust, and produced torrefied sawdust with higher HHV, greater atomic carbon content, lower atomic hydrogen and oxygen contents, less volatile matter, greater fixed carbon and less hemicellulose. Higher temperature and greater oxygen concentration were very helpful to produce more torrefied sawdust captured by a cyclone. Performance of oxidative torrefaction was similar to that of non-oxidative torrefaction. The effect of oxygen concentration was more significant at a higher temperature. Torrefied sawdust underwent size reduction during torrefaction, with smoother and cleaner surfaces compared to raw sawdust. The activation energy for non-oxidatively torrefied sawdust was higher than for oxidatively torrefied sawdust, which was in turn greater than that of raw sawdust. Sawdust particle size affected the pressure drop across the reactor.

description: Evaluación del pulido de resinas compuestas: Una revisión bibliográfica

Objetivo:

 

El objetivo de este trabajo es evaluar y comparar la eficacia de los diferentes métodos de medición del pulido de resinas compuestas. Para ello, nos enfocamos en aspectos como la rugosidad de la superficie, el brillo residual y la microestructura final de la restauración, que son los criterios de evaluación sobre los que centramos el estudio.

 

Metodología:

 

Se realizó una revisión de la literatura siguiendo las recomendaciones de PRISMA. Se buscó en bases de datos como PubMed, Scopus, Web of Science y Google Scholar desde el año 2016 hasta 2024 y en inglés y en español. Finalmente, se incluyeron un total de 16 artículos: estudios in vitro, revisiones sistemáticas y ensayos clínicos controlados aleatorios.

 

Resultados:

Los métodos más efectivos para evaluar cómo se llevó a cabo el pulido fueron aquellos que combinaban el análisis cuantitativo y el análisis cualitativo: la perfilometría óptica como método preciso para medir rugosidad (Ra < 0,2 µm); los glossmeters que permitirían estimar la retención de brillo tras 10.000 ciclos de cepillado; y el SEM que revelaba diferencias microestructurales producidas por protocolos. Los sistemas multietapa de pulido (discos de óxido de aluminio y pulidores de diamante) mostraron los mejores resultados. Las resinas nanorrellenas se mostraron con mejores resultados que las bulk-fill, especialmente con protocolos de evaluación combinados.

 

Conclusiones:

La eficacia del pulido no puede ser evaluada con un único método. Siempre resulta más interesante el uso combinado de perfilometría, reflectometría y SEM para obtener información de gran interés. Además, los sistemas multietapa, con resinas de tipo nanohíbrido o nanorrelleno eran los que permitían obtener las superficies más lisas, brillantes y duraderas. Se recomienda estandarizar los métodos de evaluación para introducir calidad clínica en las restauraciones.

description: We present optical and near-infrared (NIR) photometry of a classical nova, V2362 Cyg (= Nova Cygni 2006). V2362 Cyg experienced a peculiar rebrightening with a long duration from 100 to 240 d after the maximum of the nova. Our multicolor observation indicates an emergence of a pseudophotosphere with an effective temperature of 9000 K at the rebrightening maximum. After the rebrightening maximum, the object showed a slow fading homogeneously in all of the used bands for one week. This implies that the fading just after the rebrightening maximum ( less or equal 1 week ) was caused by a slowly shrinking pseudophotosphere. Then, the NIR flux drastically increased, while the optical flux steeply declined. The optical and NIR flux was consistent with blackbody radiation with a temperature of 1500 K during this NIR rising phase. These facts are likely to be explained by dust formation in the nova ejecta. Assuming an optically thin case, we estimate the dust mass of 10^(-8) -- 10^(-10) M_solar, which is less than those in typical dust-forming novae. These results support the senario that a second, long-lasting outflow, which caused the rebrightening, interacted with a fraction of the initial outflow and formed dust grains.

description: A sulphated glycoprotein, denoted I-SG, has previously been shown to be synthesized in Volvox under developmental control [(1982) FEBS Lett. 143, 311-315]. It is demonstrated that I-SG synthesis is restricted to a period during embryonic inversion as short as 10 min (out of the 48 h life cycle). This glycoprotein was purified and chemically characterized. 62% of its amino acid residues are hydroxyproline. Clusters of hydroxyproline residues were found to occur in its polypeptide chain. Besides arabinose and galactose, 3-O-methylgalactose and 6-O-methylgalactose were identified as constituents of I-SG.
Mapping alternative systems of accountability in residential long-term care in British Columbia and Ontario

Publisher: name: University of British Columbia
Year: 2017

description: Cases of abuse and neglect frequently arise in residential long-term care facilities. This thesis studies the systems of accountability within the residential long-term care sectors of British Columbia and Ontario. Using structured comparative case studies and documentary analysis it categorizes existing mechanisms of accountability into the five conceptions of accountability established by Bruce Stone. These are: parliamentary control, managerialism, judicial quasi-judicial, constituency relations and market. It then applies Richard Mulgan’s theory of accountability deficits to identify areas where the current mechanisms fail. Overall, it finds that contemporary reliance on alternative service delivery for the delivery of residential long-term care has significantly increased the need for new and different systems of accountability. The thesis then assesses how mechanisms of accountability can be adapted while maintaining a system that includes alternative service delivery. Changes will require clear definitions of the role of accountability mechanisms and emphasis on preventative mechanisms. Improving systems of accountability in long-term care is important, as there will be increased pressure on such systems from an ageing Canadian population. This thesis contributes to the Canadian public administration literature by examining the relationship between alternative service delivery and a complex hybrid accountability system.

description: Quasi--realistic heterotic-string models in the free fermionic formulation typically contain an anomalous U(1), which gives rise to a Fayet-Iliopolous term that breaks supersymmetry at the one--loop level in string perturbation theory. Supersymmetry is restored by imposing F- and D-flatness on the vacuum. In Phys. Rev. D 78 (2008) 046009, we presented a three generation free fermionic standard-like model which did not admit stringent F- and D-flat directions, and argued that the all the moduli in the model are fixed. The particular property of the model was the reduction of the untwisted Higgs spectrum by a combination of symmetric and asymmetric boundary conditions with respect to the internal fermions associated with the compactified dimensions. In this paper we extend the analysis of free fermionic models with reduced Higgs spectrum to the cases in which the SO(10) symmetry is left unbroken, or is reduced to the flipped SU(5) subgroup. We show that all the models that we study in this paper do admit stringent flat directions. The only examples of models that do not admit stringent flat directions remain the strandard-like models of reference Phys. Rev. D 78 (2008) 046009.

description: We numerically examine the properties of a two-dimensional system of particles which have competing long range repulsive and short range attractive interactions as a function of density and temperature. For increasing density, there are well defined transitions between a low density clump phase, an intermediate stripe phase, an anticlump phase, and a high density uniform phase. To characterize the transitions between these phases we propose several measures which take into account the different length scales in the system. For increasing temperature, we find an intermediate phase that is liquid-like on the short length scale of interparticle spacing but solid-like on the larger length scale of the clump, stripe, or anticlump pattern. This intermediate phase persists over the widest temperature range in the stripe state when the local particle lattice within an individual stripe melts well below the temperature at which the entire stripe structure breaks down, and is characterized by intra-stripe diffusion of particles without inter-stripe diffusion. This is followed at higher temperatures by the onset of inter-stripe diffusion in an anisotropic diffusion phase, and then by breakup of the stripe structure. We identify the transitions between these regimes through diffusion, specific heat, and energy fluctuation measurements, and find that within the intra-stripe liquid regime, the excess entropy goes into disordering the particle arrangements within the stripe rather than affecting the stripe structure itself. The clump and anticlump phases also show multiple temperature-induced diffusive regimes which are not as pronounced as those of the stripe phase.

Synthesis and rheological characterization of polyhydroxybutyrate with different topologies and microstructures
Creators: name: Ebrahimi, Tannaz
Publisher: name: University of British Columbia
Year: 2017

description: Series of monodispersed linear and star-shaped polyhydroxybutyrate (PHB)s were synthesized using controlled indium and zinc based complexes through immortal ring opening polymerization of β-butyrolactone (BBL) in the presence of benzyl alcohol, tris(hydroxymethyl)benzene, and dipentaerythritol chain transfer agents. The topologies of the prepared PHBs of various molecular weights were investigated using solution and melt rheological characterizations. The powerlaw relationship between the radius of gyration and hydrodynamic radii of the linear and star PHBs with the molecular weight confirmed that the molecules are self-similar. Reduced values of compactness factor relative to that of linear counterparts and exponential scalling of the zero-shear viscosity of the stars with span molecular weight confirmed the presence of branching on the PHB backbone. A series of racemic and enantiopure zinc complexes were synthesized and fully characterized for the polymerization of BBL to form high molecular weight syndiotactic PHBs (Pr up to 75%). Complex (±)-[(NNHOtBu)ZnOBn]₂ (9) showed unprecedented reactivity and control towards the polymerization of up to 20000 equivalents of BBL in the presence of 5000 equivalents of benzyl alcohol. Isothermal time sweep tests at temperatures above the melting point of the syndio-rich PHBs showed thermally stable behavior of these polymers at temperatures below 140 oC. The zero-shear viscosity of the syndio-riched PHBs was higher than their atactic counterparts and showed a power-law relationship with the molecular weight confirming the linear microstructure and the absence of cyclic or branched species in the melt. The extensional rheometry revealed high melt strength in a range of strain rates as a result of flow induced crystallization. Easy to make, indium-salan complexes were reported for the polymerization of as-received lactide. The solution state characterization of these polymers showed narrow molecular weight distributions with molecular weights closely matching the theoretical molecular weight as an indication of a robust catalytic system. These complexes are capable of polymerizing impure lactide isomers in the melt state under ambient atmospheric conditions to form high molecular weight symmetric star shaped multi-block PLAs with high melting points, up to 197 °C. This catalytic system can also be used for the formation of star-shaped PHB-PLA copolymers in inert atmosphere.
Static and dynamic forces on a permanent magnet levitating between superconducting surfaces

description: A charged magnetic microsphere (radius 100 µm) is levitating inside a superconducting niobium capacitor. Because of its charge of about 1 pC, oscillations about the equilibrium position can be excited and detected electrically. The properties of this oscillator are investigated in order to study the static and dynamic forces of magnetic levitation. We find resonance frequencies between 200 Hz and 600 Hz. The resonance frequency and the damping are amplitude dependent due to nonlinear return forces and nonlinear friction, respectively. At small amplitudes the Q value is about 106 in vacuum. A dc field can be applied to change the equilibrium position and consequently the resonance frequency. From the data the spatial dependence of the static force and of the dynamic stiffness can be determined and an empirical relation between both is established. Quite often, we find a hysteretic behavior of the static force whereas the stiffness is a reversible function of the position. Amplitude dependent damping is observed both in the decay of the free oscillations and in the dependence of the amplitude of the forced oscillations on the driving force.

We demonstrate that imaging ellipsometry is a powerful tool to detect and characterize graphene on any flat substrate. Variable angle spectroscopic ellipsometry is used to explore the dispersion of the optical constants of graphene in the visible range with high lateral resolution. In this way, the influence of the substrate on graphene’s optical properties can be investigated.
Human Thought and Artificial Intelligence: The convergence of Mind and processing the pursuit of Truth

description: The relationship between human thought and artificial intelligence (AI) is a fundamental issue in modern technology and philosophy. This article explores how human cognition and AI processing can synergize rather than compete. While traditional perspectives often view AI as a replacement for human intelligence, this work emphasizes a complementary approach where AI serves as an extension and amplifier of human thought. The paper discusses the limitations of AI based on predefined data, the dynamic nature of human cognition, and the potential for a new evolutionary step in the interaction between human intelligence and AI.

Year: 1878

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We present a method of filter diagonalization for shell-model calculations. This method is based on the Sakurai and Sugiura (SS) method, but extended with help of the shifted complex orthogonal conjugate gradient (COCG) method. A salient feature of this method is that it can calculate eigenvalues and eigenstates in a given energy interval. We show that this method can be an alternative to the Lanczos method for calculating ground and excited states, as well as spectral strength functions. With an application to the $M$-scheme shell-model calculations we demonstrate that several inherent problems in the widely-used Lanczos method can be removed or reduced.

description: The response of polycrystalline Tl–Ba–Ca–Cu–O superconducting thin films on short laser pulses has been investigated for radiation between 10 mgrm and 500 mgrm wavelength. Fast signals with time constants less than 1 ns were observed for wavelengths longer than about 100 mgrm whereas for shorter wavelengths only a bolometric signal could be detected.

description: We report on a study of the far-infrared reflection for a sintered YBa2Cu3O7 sample that contained a large portion of preferentially oriented crystallites with thea–b plane parallel to the surface and that showed extraordinary high far-infrared reflectivity. From experimental reflection data we determined, by Kramers-Kronig analysis, the dynamical conductivity and extracted the contributions due to free charge carriers and phonons, respectively. We find evidence for an anomalous behavior of the dynamical conductivity at temperatures aboveT c ; the dynamical conductivity increases strongly for temperatures approachingT c and is strongly frequency dependent. By use of the Mattis-Bardeen theory we obtain an estimate for the superconducting energy gap of 2Delta/kT c sime4.6 (forTLtT c ). We find that the lowest frequency infrared-active phonon mode is less damped in the superconducting state than in the normal state.

description: We have developed a full discourse parser in the Penn Discourse Treebank (PDTB) style. Our trained parser first identifies all discourse and non-discourse relations, locates and labels their arguments, and then classifies their relation types. When appropriate, the attribution spans to these relations are also determined. We present a comprehensive evaluation from both component-wise and error-cascading perspectives.

description: In this paper, we review recent developments in the emerging field of electron quantum optics, stressing analogies and differences with the usual case of photon quantum optics. Electron quantum optics aims at preparing, manipulating and measuring coherent single electron excitations propagating in ballistic conductors such as the edge channels of a 2DEG in the integer quantum Hall regime. Because of the Fermi statistics and the presence of strong interactions, electron quantum optics exhibits new features compared to the usual case of photon quantum optics. In particular, it provides a natural playground to understand decoherence and relaxation effects in quantum transport.

description: Preparation of superconducting Tl-Ba-Ca-Cu-O thin films by diffusion of Tl into laser evaporated Ba2Ca2Cu3Ox thin films is reported. From a sintered Ba2Ca2Cu3Ox bulk sample we prepared using a pulsed Nd:YAG laser, Ba-Ca-Cu-O thin films on sapphire and SrTiO3 single-crystal substrates. Subsequently the films were loaded with Tl by simultaneously annealing the films together with a sintered Tl2Ba2Ca2Cu3O10 sample both enclosed in a small stainless steel box; in our procedure Tl contamination was reduced to a minimum. Tc values near 100 K and critical currents of 5·103 A/cm2 at 77 K were obtained.
Have neutron stars a dark matter core?

description: Recent observational results for the masses and radii of some neutron stars are in contrast with typical observations and theoretical predictions for "normal" neutron stars. We propose that their unusual properties can be interpreted as the signature of a dark matter core inside them. This interpretation requires that the dark matter is made of some form of stable, long-living or in general non-annihilating particles, that can accumulate in the star. In the proposed scenario all mass-radius measurements can be explained with one nuclear matter equation of state and a dark core of varying relative size. This hypothesis will be challenged by forthcoming observations and could eventually be a useful tool for the determination of dark matter.

Subjects: subject: 530 Physik

description: In this paper we present a description of the Nernst electric field E generated by forced flux tube motion due to a temperature gradient backward differenceT. Depending on the value of backward differenceT with respect to a critical gradient backward differenceTcrit, we find for backward differenceT/backward differenceTcritmuch less-than 1 a regime E ∝ backward differenceT, in close analogy to the regime of thermally activated flux flow in transport current measurements (characterized by an electric field proportional to the transport current). The theory for backward differenceT

description: We report resistivity, Hall coefficient, current-voltage characteristics, and magneto-optical imaging measurements of epitaxial Co-doped BaFe_{2}As_{2} thin films deposited on MgO(001) substrate. The Hall resistivity of the films has a substantial contribution arising from anomalous Hall effect of ferromagnetic components. The critical current density (J_{c}) of the films is ~2 MA/cm^{2} at low temperatures. Differential magneto-optical images of the remanent state give similar J_{c} values and also exhibit presence of extended defects in the film.

Étude de populations d'oiseaux du Québec

description: L’île aux Basques (latitude 48°07’N; longitude 69°15’O) se situe dans l’estuaire maritime du Saint-Laurent, à 4 km au large de la ville de Trois-Pistoles, au Québec, Canada. Longue d’un peu plus de 2 km et large d’un peu moins de 1 km, l’île est en majeure partie boisée, avec un pré à une extrémité et un petit étang d’eau douce au centre. Les Razades, qui se présentent comme deux îlots rocheux, se trouvent à une dizaine de kilomètres en aval de l’île aux Basques. L’île aux Basques et les Razades, propriétés de la Société Provancher depuis 1927-29, jouissent du statut de Refuge d’oiseaux migrateurs selon les règlements de la loi sur la Convention concernant les oiseaux migrateurs du Canada. Ce dépliant de deux pages contient la liste annotée, pour les mois de mai à octobre, des 238 espèces d’oiseaux ayant été observées de 1927-2001 à l’île aux Basques et aux Razades. Comme ces îles sont en pratique inaccessibles en hiver et qu’on ne possède à peu près pas d’informations sur leur avifaune hivernale, nous avons omis de considérer les mois de novembre à avril dans la liste annotée. Pour chaque espèce, on donne: une description de l'habitat local utilisé, le statut de nidification et la constance mensuelle d'observation (calculée à partir de 23 000 mentions d'oiseaux réparties sur 558 rapports d'observations quotidiennes).

description: We have measured the AC-Stark shift of the $14D_{5/2}$ Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO$_2$-laser. We find good quantitative agreement with the model of a free electron experiencing a ponderomotive potential in the light field. In order to reproduce the observed spectra we take into account the broadening of the Rydberg state due to photoionization. The extracted cross-section is compatible with previous measurements on neighboring Rydberg states.

description: We report on the observation of a thermopile effect caused by laser radiation heating in thin films of high-Tc material. The thermopile effect is due to a transverse Seebeck effect. The transverse Seebeck effect is observable first because of the anisotropy of YBa2Cu3O7−δ, and secondly because it is possible to grow off-axis epitaxial films. The thermopile effect can be used for developing detectors for laser radiation.

description: The hybrid linear modeling problem is to identify a set of d-dimensional affine sets in a D-dimensional Euclidean space. It arises, for example, in object tracking and structure from motion. The hybrid linear model can be considered as the second simplest (behind linear) manifold model of data. In this paper we will present a very simple geometric method for hybrid linear modeling based on selecting a set of local best fit flats that minimize a global l1 error measure. The size of the local neighborhoods is determined automatically by the Jones' l2 beta numbers; it is proven under certain geometric conditions that good local neighborhoods exist and are found by our method. We also demonstrate how to use this algorithm for fast determination of the number of affine subspaces. We give extensive experimental evidence demonstrating the state of the art accuracy and speed of the algorithm on synthetic and real hybrid linear data.
