description: Slickwater hydraulic fracturing has become commonplace in tight gas developments as with Shell Canada's Groundbirch position in the Montney play. Water is a technical and non-technical issue for both surface and subsurface disciplines. Critical concerns pertaining to water at Groundbirch included sourcing water to stimulate wells, ensuring that the water used in hydraulic fracturing was not detrimental to the production of natural gas, and predicting the flows and potential storage volumes of water throughout the field such that water handling facilities could be appropriately designed enabling water to be optimally recycled. This thesis presents the author's work at Groundbirch as a pragmatic basis for developing a hydraulic fracturing water chemistry specification, water forecasts and balances for design considerations, and special analyses used to better quantify the mobility of water or aqueous phase trapping potential in tight gas sands, while emphasizing the importance of acquiring quality water rate and chemistry data.

description: Este documento surge de la misma preocupación que hace más de cuarenta años también tuvo Ángel Rama y que expuso en el significativo e influyente ensayo Diez problemas para el novelista latinoamericano . En este libro, el autor planteó diez problemas que, en su opinión, determinaron la evolución literaria latinoamericana y, en este sentido, la dificultad que hemos tenido en nuestro continente para comprender quiénes somos. Ahora bien, en ese momento, Ángel Rama no podía entender qué significaría la tecnología para el novelista del siglo xxi . Por lo tanto, en este artículo, presentamos una breve descripción de lo que propuso Ángel Rama y luego explicamos la forma en que la tecnología aparece como un nuevo problema que desafía al novelista a mantener su autenticidad en un mundo globalizado y determinado por la cultura tecnocrática.
Comunicação em Rede e a construção social da Realidade

description: A construção Social da Realidade (Berger e Luckmann) é uma teoria construtivista que encontra na linguagem e na comunicação argumentos para a explicação da génese e funcionamento da sociedade, argumentos que servem também de base a Habermas para as suas teorias sociais e políticas após a “viragem linguística”. Quando analisamos a ação das tecnologias da informação e da comunicação no processo de construção social da realidade na pós-modernidade, não esquecendo as múltiplas forças que estão implicadas neste processo, podemos chegar à conclusão de que a internet e as novas tecnologias podem ser entendidas como manifestação de uma ideologia neoliberal capitalista e que, mais que mediação da distância, estas tecnologias são, acima de tudo, dispositivos de linguagem.

description: Quality of Service (QoS) for MANETs becomes a necessity because of its applications in decisive situations such as battle fields, flood and earth quake. Users belonging to diverse hierarchical category demanding various levels of QoS use MANETs. Sometimes, even a low category user may need to send an urgent message in time critical applications. Hence providing prioritization based on user category and urgency of the message the user is sending becomes necessary. In this paper we propose Enhanced MAC parameters to support Hybrid Dynamic priority in MANETs(H-MAC). It combines both prioritization based on user categorization and dynamic exigency. Order Statistics is used to implement dynamic priority. We propose dynamic TXOP, Proportional AIFS and Proportional dynamic Backoff timers based on weights and collision, to avoid packet dropping and starvation of lower priorities. The model is simulated in ns2. We compare our results with IEEE 802.11e and show that, 16% more throughput is achieved by H-MAC during extensive collision. We also observe that starvation and packet drops are reduced with proportionate bandwidth sharing compared to the existing model.

description: The return to the quiescent state of the Anomalous X-ray pulsar XTE J1810-197 following its 2003 outburst represents a unique opportunity to probe the surface emission properties of a magnetar. The quiescent emission of XTE J1810-197 is composed of two thermal components, one arising from the whole star surface, and the other from a small warm spot on it. By modeling the magnitude and shape of the pulse profile in narrow spectral bands, we have been able to constrain the physical characteristics and geometrical parameters of the system: the two angles that the line of sight and the spin axis make with respect to the warm spot axis (ψ and ξ respectively), the angular size of the spot, and the overall surface temperature distribution. Our modeling accounts for the general relativistic effects of gravitational redshift and light bending near the stellar surface, and allows for local anisotropic emission. We found that the surface temperature distribution on the neutron star is consistent with the expectations of a dipole magnetic field configuration; the local radiation requires a pencil-beamed emission pattern, suggesting the presence of a magnetized atmosphere. For a typical value of the radius, R=13 km, the viewing parameters (symmetric for an interchange between ψ and ξ), range from ψ=ξ=38 deg to (ψ,ξ)=(52 deg, 29 deg). These angles are consistent with those obtained by modeling the AXP in outburst, with uncertainty contours reduced by a factor of 2.5.

description: We characterize galaxy correlations in the Sloan Digital Sky Survey by measuring several moments of galaxy counts in spheres. We firstly find that the average counts grows as a power-law function of the distance with an exponent D= 2.1+- 0.05 for r in [0.5,20] Mpc/h and D = 2.8+-0.05 for r in [30,150] Mpc/h. In order to estimate the systematic errors in these measurements we consider the counts variance finding that it shows systematic finite size effects which depend on the samples sizes. We clarify, by making specific tests, that these are due to galaxy long-range correlations extending up to the largest scales of the sample. The analysis of mock galaxy catalogs, generated from cosmological N-body simulations of the standard LCDM model, shows that for r<20 Mpc/h the counts exponent is D~2.0, weakly dependent on galaxy luminosity, while D=3 at larger scales. In addition, contrary to the case of the observed galaxy samples, no systematic finite size effects in the counts variance are found at large scales, a result that agrees with the absence of large scale, r~100 Mpc/h, correlations in the mock catalogs. We thus conclude that the observed galaxy distribution is characterized by correlations, fluctuations and hence structures, which are larger, both in amplitude and in spatial extension, than those predicted by the standard model LCDM of galaxy formation.

description: Jupiter and Saturn formed in a few million years (Haisch et al. 2001) from a gas-dominated protoplanetary disk, and were susceptible to gas-driven migration of their orbits on timescales of only ~100,000 years (Armitage 2007). Hydrodynamic simulations show that these giant planets can undergo a two-stage, inward-then-outward, migration (Masset & Snellgrove 2001, Morbidelli & Crida 2007, Pierens & Nelson 2008). The terrestrial planets finished accreting much later (Klein et al. 2009), and their characteristics, including Mars' small mass, are best reproduced by starting from a planetesimal disk with an outer edge at about one astronomical unit from the Sun (Wetherill 1978, Hansen 2009) (1 AU is the Earth-Sun distance). Here we report simulations of the early Solar System that show how the inward migration of Jupiter to 1.5 AU, and its subsequent outward migration, lead to a planetesimal disk truncated at 1 AU; the terrestrial planets then form from this disk over the next 30-50 million years, with an Earth/Mars mass ratio consistent with observations. Scattering by Jupiter initially empties but then repopulates the asteroid belt, with inner-belt bodies originating between 1 and 3 AU and outer-belt bodies originating between and beyond the giant planets. This explains the significant compositional differences across the asteroid belt. The key aspect missing from previous models of terrestrial planet formation is the substantial radial migration of the giant planets, which suggests that their behaviour is more similar to that inferred for extrasolar planets than previously thought.

description: Understanding mammalian cell functions has been a key factor for medical diagnostics and treatment. These dynamics range from sub-second protein folding to differentiation over days. In recent years fluorescence imaging has enabled the observation for features on the nanometer scale. However observation of the highly dynamic cellular activities has been severely hindered by both photobleaching and a limited optical resolution. Here we present plasmonic nanoscopy that combines high-speed (>1800°/s) and high-precision (<15nm) polarization modulation of the localized surface plasmon resonance of plasmonic nanoparticles imaging contrast agents to achieve non-bleaching, super-resolution imaging. Using our techniques, we demonstrated a 10-day long-term continuous imaging of nanoparticle-conjugated actin network in vitro with sub-diffraction resolution (0.140 ± 0.005λ). Finally, we demonstrated imaging of neuroblastoma cells.

description: We analyze multi-bounce propagation of light in an unknown hidden volume and demonstrate that the reflected light contains sufficient information to recover the 3D structure of the hidden scene. We formulate the forward and inverse theory of secondary and tertiary scattering reflection using ideas from energy front propagation and tomography. We show that using careful choice of approximations, such as Fresnel approximation, greatly simplifies this problem and the inversion can be achieved via a backpropagation process. We provide a theoretical analysis of the invertibility, uniqueness and choices of space-time-angle dimensions using synthetic examples. We show that a 2D streak camera can be used to discover and reconstruct hidden geometry. Using a 1D high speed time of flight camera, we show that our method can be used recover 3D shapes of objects "around the corner".

description: Adinkras are diagrams that describe many useful supermultiplets in D=1 dimensions. We show that the topology of the Adinkra is uniquely determined by a doubly even code. Conversely, every doubly even code produces a possible topology of an Adinkra. A computation of doubly even codes results in an enumeration of these Adinkra topologies up to N=28, and for minimal supermultiplets, up to N=32.

description: We discuss a holographic soft-wall model developed for the description of mesons and baryons with adjustable quantum numbers n, J, L, S. This approach is based on an action which describes hadrons with broken conformal invariance and which incorporates confinement through the presence of a background dilaton field. Results obtained for heavy-light meson masses and decay constants are consistent with predictions of HQET. In the baryon sector applications to the baryon masses, nucleon electromagnetic form factors and generalized parton distributions are discussed.

Cryptosporidium detection through antibody immobilization on a solid surface
Creators: name: Das, Rony
Publisher: name: University of British Columbia

description: Current detection of pathogenic organisms in water relies on the use of indicators (turbidity, Escherichia coli, total coliforms, fecal coliforms etc.) or time consuming assays that can only be done in a specialized laboratory. In this research a simple assay was developed for rapid and sensitive recovery and identification of waterborne pathogens from environmental samples. The assay developed involves capturing target pathogens onto an activated capture surface, exposing the capture surface to antibody conjugated micro-retroreflectors, and then inserting the capture surface into an inexpensive, simple reader to detect the retroreflection signal to confirm the presence of target pathogens. Antibody (capture molecule: IgG and IgM) fragments specific to Cryptosporidium, as a model waterborne pathogen, were produced and immobilized site specifically and randomly onto gold-coated surfaces as well as corner cube micro-retroreflectors (ccμRR). A shear test performed to determine the critical shear stress that antigen-antibody bonds are able to endure showed that the organism-antibody bond could resist up to a shear stress of 126 dyne/cm2 and beyond this critical value immobilized Cryptosporidium oocysts were lost from the system. Capture tests were designed to determine the optimum operating conditions of the parallel flow sampling device using IgG-Fab', IgG-Fab, and IgM-Fab' activated surfaces. Capture efficiencies did not differ significantly within the range of flow rate used (14 – 42 mL/min), but improvement was noticed when the cell depth was decreased from 250 μm to 125 μm. Site specifically oriented IgG-Fab' activated surfaces resulted in significantly better capture efficiencies than surface with randomly immobilized IgG-Fab fragments. The capture efficiency of IgG-Fab' activated surfaces was significantly different than that of IgM-Fab' immobilized surfaces. There was no significant difference in capture efficiency using the surfaces activated with dilutions (1:8, 1:4, 1:2, and 1:1.5) of antibody fragments originally made of 500μg of IgG1 antibody. The use of BSA as a blocking agent improved the reproducibility of the capture efficiency. CcμRR were suspended in solution and activated with IgG-Fab' to use as a recognition molecule. The current set up of the detector system is capable of detecting the presence and absence of a large number of ccμRR attached on the solid surface.

We find that v_4 is more sensitive to the viscosity at low temperatures than v_2. At RHIC v_2 is mostly affected by the viscosity around the phase transition, but the larger the collision energy, the more the quark-gluon plasma viscosity affects v_2.

description: This article presents a comparative study of the oral English proficiency gains of two groups of students, namely mobility students before and during the COVID-19 pandemic (n?=?26), who were matched for background variables such as pre-departure oral proficiency, duration of stay, accommodation, and destination. Oral proficiency was measured before and after the stay using the Oral Proficiency Interview by Computer (OPIc). Results indicate that students staying abroad before the outbreak of the pandemic made significant progress while students staying abroad during the pandemic did not. Student comments suggest that this may be related to the measures taken to contain the pandemic, limiting opportunities for social networking and interaction. However, this impression could not be supported by statistical analyses of the self-reported number of social contacts or amount of English language use. The results point to the need for consideration of qualitative aspects of social interactions and language use and a more frequent and situated assessment of these.

description: We propose a phase space method to propagate a quantum wavepacket driven by a strong external field. The method employs the so-called biorthogonal von Neumann basis recently introduced for the calculation of the energy eigenstates of time-independent quantum systems [A. Shimshovitz and D.J. Tannor, arXiv:1201.2299v1]. While the individual elements in this basis set are time-independent, a small subset is chosen in a time-dependent manner to adapt to the evolution of the wavepacket in phase space. We demonstrate the accuracy and efficiency of the present propagation method by calculating the electronic wavepacket in a one-dimensional soft-core atom interacting with a superposition of an intense, few-cycle, near-infrared laser pulse and an attosecond extreme-ultraviolet laser pulse.

Knowing when to stop: how noise frees us from determinism

description: Deterministic chaotic dynamics presumes that the state space can be partitioned arbitrarily finely. In a physical system, the inevitable presence of some noise sets a finite limit to the finest possible resolution that can be attained. Much previous research deals with what this attainable resolution might be, all of it based on global averages over a stochastic flow. We show how to compute the locally optimal partition, for a given dynamical system and given noise, in terms of local eigenfunctions of the Fokker-Planck operator and its adjoint. We first analyze the interplay of the deterministic dynamics with the noise in the neighborhood of a periodic orbit of a map, by using a discretized version of Fokker-Planck formalism. Then we propose a method to determine the 'optimal resolution' of the state space, based on solving Fokker-Planck's equation locally, on sets of unstable periodic orbits of the deterministic system. We test our hypothesis on unimodal maps.

Rapid design of steel monosymmetric plate and box girders
Creators: name: Khorasani, Milad
Publisher: name: University of British Columbia
Year: 2010

description: This thesis deals with the design process for steel plate girders and box girders. The design of plate girders is quite prescriptive. A more fundamental approach is required for the design of box girders. Equations explicitly for the design of plate and box girders are heavily influenced by empirical data. This work considers pure steel box girders only, and does not include the design of composite box girder sections. CAN/CSA-S6-00 “Canadian Highway Bridge Design Code” provides detailed design requirements for these composite girders. The design of plate girders follows mostly the requirements specified in the “Handbook of Steel Construction” CAN/CSA-S16.1. However, the S16.1 clauses relating to bending capacity are not well suited for the design of monosymmetric plate girders. Therefore, the code recommends a rational method of analysis such as methods explained in the Structural Stability Research Council’s Guide to Stability Design Criteria for Metal Structures. In addition, “Canadian Highway Bridge Design Code” CAN/CSA-S6-00 provides additional design information for monosymmetric sections. A steel box girder excluding composite design, hereon simply referred to as a box girder, is a purely steel section that could be designed in accordance with CAN/CSA-S16 “Limit States Design of Steel Structures”. However, this standard focuses on clauses for plate girder design, with little specific reference to box girders. Therefore, additional reference materials such as: 1) Guide to Stability Design Criteria for Metal Structures, 2) Crane Manufacturer’s Association of America (CMAA 74-2) standards, and 3) Canadian Highway Bridge Design Code are used for the design of monosymmeteric box girders. An integrated design and analysis environment in a form of formatted spreadsheet is implemented to ease the design process. The spreadsheet checks for both strength and serviceability requirements according to the applicable codes and standards. Included with this project is a clear procedure manual in chapter 7, so that the spreadsheet can be utilized for commercial design.

description: For every variety of algebras over a field, there is a natural definition of a corresponding variety of dialgebras (Loday-type algebras). In particular, Lie dialgebras are equivalent to Leibniz algebras. We use an approach based on the notion of an operad to study the problem of finding special identities for dialgebras. It is proved that all polylinear special identities for dialgebras can be obtained from special identities for corresponding algebras by means of a simple procedure. A particular case of this result confirms the conjecture by M. Bremner, R. Felipe, and J. Sanchez-Ortega, arXiv:1108.0586.

description: In this diploma thesis I deal with the research of the flora and vegetation of three unused areas of Brno, in which will or may be built city parks in the future. These areas are Planýrka, the area of the former Hády tailings pond (Hapal's Park) and the location where Houbalova Park will be built. The aim by field research was to record the species of plants, document the vegetation of the defined areas and describe and characterize these areas based on the data obtained. The data was mainly obtained by floristic survey, recording phytocenological relevés, photographing vegetation using a drone and, last but not least, a detailed literature search of the natural conditions of the defined areas, botanical resources and databases, but also research on the use of the areas in the past, present and also in the future. A partial aim was to create a map of actual vegetation of the studied areas. In the field, I recorded a total of 26 phytocenological relevés representing mainly ruderal, scrub and grass vegetation and their combinations. In total, I found 389 taxa of vascular plants, of which 27 are endangered (4 protected by law) and 26 are invasive. The work also includes a documentary herbarium of selected taxa which is stored in the BRNU. Other floristic survey data are published in the iNaturalist application (NDOP) and recorded relevés are stored in the ČNFD.

description: In this thesis, we give a complete calculation of the coefficients of ordinary equivariant cohomology with constant coefficients, graded by the real representation ring of a finite group, where the group is the dihedral group of order 2p for an odd prime p, and when the group is the quaternion group. Another independent topic will be equivariant complex cobordism. We calculate the coefficient ring of homotopical equivariant complex cobordism for the symmetric group on three elements. We also study the relation between the coefficient ring of equivariant complex cobordism and the universal Lazard ring of equivariant formal group laws for finite abelian groups, and prove a result generalizing classical Quillen's Theorem.

description: We investigate polarization properties of neutral exciton emission in single self-assembled InAs/GaAs quantum dots. The in-plane shape and strain anisotropy strongly couple the heavy and light hole states and lead to large optical anisotropy with non-orthogonal linearly polarized states misaligned with respect to the crystallographic axes. Owing to a waveguiding experimental configuration, luminescence polarization along the growth axis has been observed revealing the presence of shear components of the deformation tensor out of the growth plane. Resonant luminescence experiments allowed determining the oscillator strength ratio of the two exciton eigenstates. Valence band mixing governs this ratio and can be very different from dot to dot, however the polarization anisotropy axis is quite fixed inside a scanned area of one \mum^{2} and indicates that the in-plane deformation direction to which it is related has a correlation length of the order of magnitude of one \mum^{2}.

description: Platinum-black (Pt-B) has been demonstrated as an excellent electrocatalytic material for the electrochemical oxidation of hydrogen peroxide (H2O2). As Pt-B films can be deposited electrochemically, micro- and nano-sized conductive transducers can be modified with Pt-B. Here, we present the potential of Pt-B micro- and sub-micro-sized sensors for the detection and quantification of hydrogen (H2) in solution. Using these microsensors, no sampling step for H2 determination is required and e.g., in photocatalysis, the onset of H2 evolution can be monitored in situ. We present Pt-B- based H2 micro- and sub-micro-sized sensors based on different electrochemical transducers such as microelectrodes and atomic force microscopy (AFM)- scanning electrochemical microscopy (SECM) probes, which enable local measurements e.g., at heterogenized photocatalytically active samples. The microsensors are characterized in terms of limits of detection (LOD), which ranges from 4.0 µM to 30 µM depending on the size of the sensors and the experimental conditions such as type of electrolyte and pH. The sensors were tested for the in situ H2 evolution by light-driven water-splitting, i.e., using ascorbic acid or triethanolamine, showing a wide linear concertation range, good reproducibility, and high sensitivity. Proof-of-principle experiments using Pt-B-modified cantilever-based sensors were performed using a model sample like platinum substrate to map the electrochemical H2 evolution along with the topography using AFM-SECM.

description: Properties of phonons - quanta of the crystal lattice vibrations - in graphene have attracted strong attention of the physics and engineering communities. Acoustic phonons are the main heat carriers in graphene near room temperature while optical phonons are used for counting the number of atomic planes in Raman experiments with few-layer graphene. It was shown both theoretically and experimentally that transport properties of phonons, i.e. energy dispersion and scattering rates, are substantially different in the quasi two-dimensional system such as graphene compared to basal planes in graphite or three-dimensional bulk crystals. The unique nature of two-dimensional phonon transport translates to unusual heat conduction in graphene and related materials. In this review we outline different theoretical approaches developed for phonon transport in graphene, discuss contributions of the in-plane and cross-plane phonon modes and provide comparison with available experimental thermal conductivity data. Particular attention is given to analysis of recent theoretical results for the phonon thermal conductivity of graphene and few-layer graphene, and the effects of the strain, defects and isotopes on the phonon transport in these systems.
