Cinétique de la photodéposition d'alcènes sur le SI(111).
Creators: name: Laferrière, Marie.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Chemistry, Physical.

description: La surface du Si(111) est hydrogénée en utilisant une variante de la méthode RCA, suivi d'une immersion dans le NH 4 F 40%. Cette surface hydrogénée est caractérisée par spectroscopie infrarouge dans un arrangement géométrique de multiples réflexions internes. Le pic de réflectance des Si-H est mince et intense ce qui indique que la surface hydrogénée est homogène et atomiquement plate. En présence de 1-octène et de 1-hexadécène, une monocouche alkyle est formée par exposition à une radiation UV. Ces monocouches alkyles ont été caractérisées par spectroscopie infrarouge. L'intensité relative des bandes de réflectance des étirements symétriques et asymétriques des méthylènes est comparable aux valeurs publiées pour des chaînes de dimensions comparables. Les mesures d'absorbance dans la polarité s et p permettent de déterminer un angle d'inclinaison pour le 1-hexadécène adsorbé par rapport à la normale qui varie de 18° à 45°. La photodéposition de 1-hexadécène a été suivie par spectroscopie in-situ. Ces spectres présentent des bandes unipolaires et bipolaires. Une étude cinétique des spectres qui présentent des bandes unipolaires est faite pour déterminer un mécanisme d'adsorption. Les résultats suggèrent un processus d'adsorption qui serait compatible avec un processus radicalaire en chaîne.
Tuning in to Kids: A pilot study of the intensive delivery of an emotion-focused early intervention program for children with emerging conduct problems
Creators: name: Mastromanno, Bianca Katarina
Publisher: name: Swinburne
Year: 2024

description: This thesis presents an investigation of the one-to-one delivery of the Tuning in to Kids (TIK) parenting program. TIK is an emotion-focused group program, that teaches parents over 8 sessions, how to respond to their children in ways that foster their emotional competence. As improving children's emotional competence often translates to improvements to behaviour problems, this research sought to assess whether a one-to-one version of this traditionally group-based program could also provide improvement to young children's behavioural difficulties. Our positive findings mean that this program can now reach a wider client group who may require or prefer one-to-one parenting support.

Subjects: subject: Chemistry, Organic.

description: 2-Bromoethanol and 2-bromoethylamine hydrobromide have been shown to behave analogously to annotinine cholorohydrin on reduction with chromium(II) chloride. 2-Bromoethanol yielded 20% ethylene and was shown to undergo considerable hydrolysis under the reaction conditions. 2-Bromoethylamine hydrobromide yielded both ethylene and ethylamine. 2-Chloroethanol was not reduced under the conditions used. Phenacyl acetate yielded 96% acetophenone separated as the 2-4-dinitrophenylhydrazone. A number of compounds have been reduced and the chromium(III) products of reduction identified spectroscopically as well as separated on an ion exchange resin. Phenacyl acetate, 2-nitropropane, alpha-chloroacetophenone, alpha-bromoacetophenone and trans 1-2-dibromocyclohexane yielded mainly Cr(H2O)6+++. Carbon tetracholoride, p-toluenesulfonyl chloride and tetra-bromoethane yielded CrX(H 2O)5++. There is therefore an anomaly in the behavior of trans 1-2-dibromocyclohexane and tetrabromoethane. The chromium(II) perchlorate reduction of benzyl chloride has been shown to involve formation of an intermediate organo-chromium compound of a type previously unknown. This compound has been named benzylpentaaquochromium(III) perchlorate. Countercurrent distribution has been used to demonstrate the presence of only one chromium organic compound and to obtain a pure solution of perchlorate. Separation was carried out at 5°C. with the solvent system 0.01M. perchloric acid-butanol and gave after seventy transfers a separation of the chromium organic compound (partition coefficient 0.35) from Cr(H 2O)6+++ and Cr(H2O)5Cl ++. Solutions of the benzylchromium(III) perchlorate varied from yellow to reddish brown depending on the concentration. The compound has a molar extinction coefficient of 1,830 at 358 mmu. and 49 at 54 mmu. Decomposition of the complex in the absence of oxygen yielded bibenzyl, in the presence of oxygen, benzaldehyde. Catalytic hydrogenation yielded toluene. Solutions of the complex reacted very quickly with aqueous mercuric chloride with no change in the pH of the solution to give benzylmercuric chloride and Cr(H 2O)6+++ in equimolar amounts. On this basis the compound has been designated as a chromium(III) complex with one benzyl group per chromium atom and two positive charges. The six coordinate positions normal for chromium(III) are completed by five molecules of water and a normal octahedral structure is proposed.

description: Streptococcus pneumoniae is a major cause of pneumonia, sepsis and meningitis. The pore-forming toxin pneumolysin is a key virulence factor of S. pneumoniae, which can be sensed by the NLRP3 inflammasome. Among the over 90 serotypes, serotype 1 pneumococci (particularly MLST306) have emerged across the globe as a major cause of invasive disease. The cause for its particularity is, however, incompletely understood. We therefore examined pneumococcal infection in human cells and a human lung organ culture system mimicking infection of the lower respiratory tract. We demonstrate that different pneumococcal serotypes differentially activate inflammasome-dependent IL-1β production in human lung tissue and cells. Whereas serotype 2, 3, 6B, 9N pneumococci expressing fully haemolytic pneumolysins activate NLRP3 inflammasome-dependent responses, serotype 1 and 8 strains expressing non-haemolytic toxins are poor activators of IL-1β production. Accordingly, purified haemolytic pneumolysin but not serotype 1-associated non-haemolytic toxin activates strong IL-1β production in human lungs. Our data suggest that the evasion of inflammasome- dependent innate immune responses by serotype 1 pneumococci might contribute to their ability to cause invasive diseases in humans.

description: For many years, the international scientific community has invested enormous efforts in the Human Genome sequencing project. The sequencing of the 23 human chromosomes is almost completed. This demonstrates that we now have to aim our efforts at improving their efficiency, and therefore resolution and speed are now the key issues. First, the effect of attractive analyte-gel interactions (we will study globular analytes here, proteins for example) will be examined within the framework of the Guo-Mercier-Slater model. It will be shown that it is possible to take into account such interactions and still calculate exact mobilities for various analytes and gel structures. Next, we will concentrate on the problems associated with the separation of chromosomal DNA (very long chains). Using Monte Carlo simulations, we will try to reproduce the dynamics of long DNA chains in three different experimental systems. (Abstract shortened by UMI.)
Gas and vapor permeation through polymer membranes.
Creators: name: Feng, Xianshe.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Engineering, Chemical.

description: The permeation data of CO$\sb2$/CH$\sb4$ mixtures through cellulose acetate membranes were analyzed. The pore flow model initially used for pure gas permeation was extended to the permeation process of gas mixtures. The permselectivity calculated using the model was compared with the experimental data, and the results showed the applicability of the model to the description of gas mixture permeation process. The effects of feed composition, operating pressure and the pore size of the membrane on the permeability and selectivity of the membrane were determined and interpreted on the basis of the pore flow model. The separation of organic vapors from air was attempted by means of polyimide membranes at ambient temperature. The membranes were prepared by a phase inversion technique and then dried using a solvent exchange method. The experimental results show that the permselectivity depended on the porous structure of the membrane which can be controlled by the membrane making conditions. The effects of several parameters involved in the procedure for membrane preparation on membrane performance were determined.
Mathematical problems in comparative genomics
Creators: name: Xu, Wei
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Mathematics.

description: In this thesis I look at several fundamental mathematical problems in the area of comparative genomics. To understand the probabilistic behaviors of genomic distances and to devise statistical tests to see whether there is significant evolutionary signal remaining in the gene orders, I derive the probability distributions for DCJ distance, reversal distance and breakpoint distance. To utilize these validated evolutionary signals in recovering the phylogeny of species, I develop a graph decomposition theory to effectively reduce the size of the median problem, which lies at the heart of the rearrangement based phylogeny problem and has been proven NP-hard. My decomposition theory enables recursive reductions of the size of the problem by discovering adequate subgraphs in the multiple breakpoint graphs which are the graphic representation of the median problems. The results on simulated data with varying parameters show the power of the theory and the effectiveness of the corresponding algorithm--- ASMedian. With various possible improvements, this theory should lead to practical methods applicable to most biology instances.
A multiple input-output theorem leading to a new equalizer structure.
Creators: name: Cheung, Chung Yin.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Engineering, Electronics and Electrical.

description: The study of the multiple-input/output inverse theorem (MINT) to realize exact inverse filtering has led to the proposal of new solution types. Digital processing functions of MINT other than the exact inverse filtering are explored. One such realization of MINT is the selective reception, filtering and distribution of signals in a multichannel system. This is demonstrated with the design of equalizers for a speakerphone system. Practical implementation problems associated with common zeros or close zeros in the channels are discussed and different solutions are proposed to address these issues. One of them is the use of the Minimum Norm Solution with system delay. Finally a novel equalizer structure, based on MINT, is proposed for realizing inverse filtering of a single analog transmission channel. Simulations show that its performance is comparable to that of the conventional equalizer based on the Least Square Error criterion.
Effect of transverse convex surface curvature on turbulent fluid flow and heat transfer in concentric annuli with moving cores.
Creators: name: Lee, Sang Hun.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Engineering, Mechanical.

description: This study investigates the effect of Transverse Convex Surface Curvature of the inner core (T.C.S.C) on the fully developed fluid flows in a concentric annulus with a moving core, by analytically predicting friction forces, velocity profiles, temperature profiles and heat transfer in terms of convex surface curvature, radius ratio, Prandtl number, Reynolds number and relative velocity. The analytical predictions are produced by a mathematical model based on the variable von Karman constant, kappai, proposed by Kim and Lee [1] and the variable van Driest damping parameter, Ai+, proposed in previous research by Suk [2]. The computer program developed for this study employs a numerical process to match velocity and temperature profiles with force and energy balances and calculates the desired momentum and thermal characteristics. The solutions are found in the case of the heat transfer where the inner core surface is uniformly heated and the outer insulated. It is assumed that the fluid flow is turbulent everywhere and the thermodynamic fluid properties are independent of temperature. It is concluded that in the fully developed turbulent flow in a concentric annulus with a moving core, the effects of Transverse Convex Surface Curvature (T.C.S.C), core velocity and turbulent motion on the momentum and heat transfer characteristics of the flow seem significant.
Transformational change: Perceptions of process and outcomes by nursing staff in a health care facility.

Subjects: subject: Health Sciences, Education.

description: This qualitative exploratory case study focused on how nursing staff perceived a complex transformational change within a large tertiary care teaching hospital. In an effort to improve the understanding of transformational learning and change, this study examined a change that required nursing staff to critically reflect on their practice and if necessary change their values, beliefs and attitudes. The objectives of the transformational innovation were to increase professional accountability and authority by changing the decision-making of nursing staff to a more autonomous process. The structural changes introduced included implementation of unit councils and primary nursing. Study data consisted of documentation collected over a three and a half year period during the implementation of the transformational change. During the analysis, similar phrases were coded and categorized and then re-categorized into major patterns or ideas reflecting perceptions of the innovation, transformational learning process, and outcomes of the change. Results describe the concerns, learning needs, and system considerations that influenced staff when implementing a transformational change. The results of this study will be of interest to administrators and educators as they prepare staff for future challenges.
Fluorescence characteristics of picocyanobacteria: Effects of light and nitrogen availability.
Creators: name: McMurter, Heather J. G.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1992
Subjects: subject: Biology, Microbiology.

description: The general objective of this thesis was to examine the effects of key environmental variables on fluorescence characteristics of picocyanobacteria using both culture and field experiments. Fluorescence ratios of phycoerythrin (PE) to phycocyanin (PC), and PE to Chl a, were found to be good surrogates of pigment ratios. The severity of nitrogen stress, as measured by the reduction in carbon to nitrogen ratios, PBP, and fluorescence ratios, appeared to be related to the pigment types of picocyanobacteria. Only slight changes in fluorescence ratios can be expected between high full spectrum and low monochromatic growth irradiance (PSII light) as a result of the small differences in PUR between these two environments. The fluorescence characteristics of low light acclimated picocyanobacteria can also be significantly influenced by growth rate. Depth patterns in fluorescence ratios in response to light and nitrogen availability were found to be consistent with differences in the seasonal and between-lake abundance of two populations of PE-picocyanobacteria.

Year: 1996
Subjects: subject: Engineering, Civil.

description: In recent years, high-strength concrete (HSC) has gained a more widespread acceptance in the construction industry. In spite of the advantages inherent to HSC, concerns still exist about its relative brittleness, particularly in regions of high seismic risk. An experimental and analytical investigation was conducted to study the behaviour of circular HSC columns subjected to simulated seismic loading. The experimental program included the testing of nine full-scale circular columns under combined axial compression and lateral load reversals. The emphasis was on the strength and deformation characteristics in relation to various confinement parameters. These parameters included the compressive strength of concrete, the yield strength, volumetric ratio and spacing of transverse reinforcement, the level of axial load, the type of circular reinforcement, and the presence of the concrete cover. The effects of test parameters were analysed by comparing the force-displacement relationships among pairs of companion specimens. The results show that ductile behaviour can be obtained from HSC columns subjected to lateral deformation reversals, provided they are suitably confined. (Abstract shortened by UMI.)

description: In current wastewater treatment industry, there are many treatments & degradation techniques to remove pollutants. Most of these methods are high in cost and normally cause subsequent contamination to the environment. This research is to develop a low-cost wastewater treatment system. It is simple to operate, with all-natural components and no subsequent contamination to the environment. Micronutrient Technique (MNT) was applied together with Vermifiltration (VF) and Natural Media Filtration (NMF). We named this technique "MVN". MVN technique is a good low cost, medium efficient, zero sludge and zero odour wastewater treatment system for rural and off grid applications.

A novel method for the decrease of phenolic content in commercial canola meal using an enzyme preparation secreted by the white-rot fungus Trametes versicolor.
Creators: name: Lacki, Karol M.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Agriculture, Food Science and Technology.

description: This research project was focused on the development of a novel enzymatic method for upgrading commercial canola meal by decreasing its phenolic content. The new method is based on the enzymatic transformations of sinapic acid esters (SAE) and free sinapic acid (SA), the two main constituents of the phenolic fraction of canola meal (CM), using an enzyme preparation secreted by the white-rot fungi Trametes versicolor ATCC 42530. The study was divided into three parts: (1) enzyme production; (2) characterization of the enzyme produced--a model enzymatic system; (3) enzymatic upgrading of commercial canola meal--a canola meal system. The enzyme preparation produced was characterized in the model enzymatic system using sinapic acid (SA), sinapine (SIN) and sinapaldehyde (SALD). The results showed that the enzyme is inhibited by high concentrations of SIN and SA. Depending on the substrate, the optima temperatures and pH are in the range of 50$\sp\circ$C-60$\sp\circ$C and 3.3-4.5, respectively. The enzyme was very thermostable; the maximum thermal stability was noticed at pH values between 4.5 and 6.5. Sodium azide was a strong inhibitor of this enzyme while its activity was not affected by EDTA. Based upon the results obtained, the enzyme was characterized as a polyphenol oxidase. The overall transformation of SA was described by a mathematical model based on the Theorell-Chance Bi-Bi mechanism with oxygen as the first substrate, and the second substrate being one of the alternate phenolic compounds: SA, DAD and the unknown compound formed via the thermolysis of DAD. The modeling of sinapine transformation was also considered in this work. A mechanistic model, based on the Theorell-Chance Bi-Bi mechanism, that simultaneously predicted the effects of the concentrations of the enzyme, SIN and oxygen, for any given pH and temperature level, on the rates of the enzymatic reaction was formulated. The model parameters were estimated following the new procedure developed in this work for analyzing data concerning the effects of pH and temperature on enzyme activity. The formula relating the optimum pH of the reaction with the temperature was proposed. The enzyme preparation produced and subsequently characterized was used in the novel method to decrease the phenolic content in commercial CM, which was based on the addition of the enzyme to the meal-buffer slurry. It was found that: (1) the natural buffering capacity of CM resulted in the negligible effect of the pH of the buffer, which was used as the continuous phase in the process, on the extent of SAE decrease; (2) the system was saturated with the enzyme when the enzyme concentration was 4 nkat per mL of the continuous phase; (3) the optimum temperature was 50$\sp\circ$C.

description: Since Fall 2012, Roots of Contemporary Issues (RCI; HISTORY 105/305) has served as the foundational, and only required, course for Washington State University undergraduates. All sections feature a term length individual research project with a scaffolded series of Library Research Assignments and a culminating final research paper or portfolio. Both in Fall 2020 and 2022, the Pullman RCI and History Department librarians surveyed students about resources (databases) they opted to use to find the central materials for the project. The first round of research (n=71) was during the Covid Pandemic, characterized by the physical library closure and hiatus from research instruction workshops. The second round (n=131) was after the library reopening and resumption of research workshops. In addition to pandemic implications, this poster will feature explanations of trends in student database usage for scholarly history monographs, history journal articles, and historical primary sources. Focusing on primary sources, the researchers also learned about the format types sought (e.g., newspaper articles, government documents, personal papers) and self-reported difficulties students experienced in locating effective primary sources. Poster viewers will gain knowledge about the fixed mindset students often display as they misguidedly search a known and trusted database for material types which might not be well represented, or are otherwise challenging to discover in that system. A final factor at play in this research are the student generated research topics/questions, which also affect database selection. Poster readers will get an overall better understanding of student information seeking behaviors.

description: Child and youth injury prevention research in Canada has lagged behind other Organisation for Economic Co-operation and Development nations, despite existing surveillance systems and longitudinal data. A critical need to improve access to the available data, as well as need to tailor its display and interpretation, was identified by injury prevention stakeholders involved in research, policy, and practice. The Canadian Atlas of Child and Youth Injury Prevention ("the Atlas") was developed to address this need. Following a series of iterative consultation meetings and a pilot testing session, the Atlas was scaled up with national data. Two testing sessions were held to evaluate the tools. The Atlas is comprised of three main components: data, indicators, and visualizations. The accessibility of the dashboard is enhanced by customization of data visualizations and data outputs to suit the user's needs. Overall feedback indicated that the tools were easy to use, and that the interface was intuitive and visually appealing. The Canadian Atlas of Child and Youth Injury Prevention provides readily accessible information to injury prevention practitioners, policy makers and researchers, helping to chart pathways to success in improving the child and youth injury prevention system in Canada.

Publisher: name: Swinburne
Year: 2024

description: In this project, a novel geothermal pavement system was developed with construction and demolition (C&D) wastes for extraction of renewable energy from pavements. The responses of C&D materials under combined cyclic loads and temperature were evaluated using temperature-controlled testing and machine learning predictive modeling. The thermal conductivity of C&D waste was characterized using prototype divided-bar equipment. The thermal performance of the geothermal pavements was investigated by small-scale prototype testing and numerical simulations. The deformation responses of the geothermal pavements under long-term cyclic loads were assessed using large-scale tank testing.

description: We explore trends in galaxy properties with Mpc-scale structures using catalogues of environment and large-scale structure from the Galaxy And Mass Assembly (GAMA) survey. Existing GAMA catalogues of large-scale structure, group, and pair membership allow us to construct galaxy stellar mass functions for different environmental types. To avoid simply extracting the known underlying correlations between galaxy properties and stellar mass, we create a mass matched sample of galaxies with stellar masses within 9.5 ≤ log M*/h−2 M⊙ ≤ 11 for each environmental population. Using these samples, we show that mass normalized galaxies in different large-scale environments have similar energy outputs, u − r colours, luminosities, and morphologies. Extending our analysis to group and pair environments, we show that galaxies that are not in groups or pairs exhibit similar characteristics to each other regardless of broader environment. For our mass controlled sample, we fail to see a strong dependence of Sérsic index or galaxy luminosity on halo mass, but do find that it correlates very strongly with colour. Repeating our analysis for galaxies that have not been mass controlled introduces and amplifies trends in the properties of galaxies in pairs, groups, and large-scale structure, indicating that stellar mass is the most important predictor of the galaxy properties we examine, as opposed to environmental classifications.

description: Previous research indicates that criminalization of sex work is associated with harms among sex workers. In 2013, the Vancouver Police Department changed their sex work policy to no longer target sex workers while continuing to target clients and third parties in an effort to increase the safety of sex workers (similar to “end-demand sex work” approaches being adopted in a number of countries globally). We sought to investigate the trends and correlates of rushing negotiations with clients due to police presence among 359 sex workers who use drugs in Vancouver before and after the guideline change. Data were derived from three prospective cohort studies of people who use drugs in Vancouver between 2008 and 2014. We used sex-stratified multivariable generalized estimating equation models. The crude percentages of sex workers who use drugs reporting rushing client negotiations changed from 8.9% before the guideline change to 14.8% after the guideline change among 259 women, and from 8.6 to 7.1% among 100 men. In multivariable analyses, there was a significant increase in reports of rushing client negotiation after the guideline change among women (p = 0.04). Other variables that were independently associated with increased odds of rushing client negotiation included experiencing client-perpetrated violence (among both men and women) and non-heterosexual orientation (among women) (all p < 0.05). These findings indicate that despite the policing guideline change, rushed client negotiation due to police presence appeared to have increased among our sample of female sex workers who use drugs. It was also associated with client-perpetrated violence and other markers of vulnerability. These findings lend further evidence that criminalizing the purchase of sexual services does not protect the health and safety of sex workers.

description: This thesis is a study of modulation techniques which could be used to provide Asymmetric Digital Subscriber Line (ADSL) and Very-high-speed Digital Subscriber Line (VDSL) services over Unshielded Twisted Pair (UTP). Three all-digital modulations are considered: Carrierless AM-PM (CAP), FFT Discrete Multitone (FFT-DMT) and Cosine Modulated Filter Bank Discrete Multitone (CMFB-DMT). The relative merits of the three modulations are examined at two data rates, 6 Mbps and 26 Mbps, which are representative of downstream ADSL and VDSL rates, respectively. Block diagrams and mathematical descriptions are provided for all three modulations. A discussion of modeling the UTP channel and a number of impairments, namely AWGN, self-FEXT, NEXT, narrow-band interference and impulse noise, is also included. Time-domain BER simulation strategies are outlined for all three modulations. The simulated BER performance of 16-CAP and the two multicarrier modulations in the presence of AWGN is presented. The simulated BER performance in the presence of AWGN of 16-CAP VDSL with emission masking is included. The spectral isolation properties of the CMFB and FFT filters are examined briefly. The computational complexity in terms of real operations per bit is considered for 16-CAP, CMFB-DMT and FFT-DMT at ADSL and VDSL data rates. (Abstract shortened by UMI.)

description: The purpose of this study was to understand what professional organizations, specifically the American Teachers Association (ATA) and the National Education Association (NEA), communicated to their members about participatory democracy in the Civil Rights Era. The time period considered for this study is 1954 -1968. Major publications of the ATA and the NEA as well as archival records of the NEA ATA Joint Committee revealed themes in the communication from each organization to their members. The ATA, communicated to mostly Black teachers (in the South) that Black teachers and students should be treated equally, that Black students should be prepared for citizenship in a democracy, and that integration was a worthy goal with hefty consequences for Black students and teachers. American democracy, according to the ATA, would be improved and enriched by the participation of Black students. Conversely, the NEA communicated to mostly White teachers (in the South) that students should know about the democracy with a heavy emphasis on patriotism. The NEA largely ignored race relations from 1955-1963, then communicated some to teachers about integration efforts going on in various cities, and largely framed all articles about Black students around disadvantage and cultural deprivation. The NEA-ATA Joint Committee undertook projects and held meetings to support improvements in Intergroup Education, human relations, and broaden understanding of the status of education for Black students. The ATA communicated about those projects to their members, through The Bulletin. The NEA did not communicate about the Joint Committee projects to their members through the Journal, except in one article in 1966 that both announced the merger and recounted the work of the Joint Committee. Members of the ATA from 1954 to 1966, primarily Black teachers in the South, and members of the NEA, who were primarily White teachers in the South, received very different messages about equality and participatory democracy from their professional associations through The Bulletin of the ATA and the NEA’s Journal.

description: A combined experimental and analytical research was conducted to investigate behaviour of low-rise concrete shear walls under simulated seismic loading. The experimental part of the research program includes tests of two large-scale shear wall specimens under inelastic load reversals. The walls were 1500 mm high and 100 mm thick, and had either 2000 mm or 1500 mm lengths, producing aspect ratios of 0.75 and 1.0. The effect of aspect ratio on shear sliding and failure modes was one of the major test parameters. The results indicated that both walls were able to develop flexural yielding and failed in crushing of diagonal struts. Little or no strength decay was observed up to approximately 0.92% and 1.83% lateral drift in walls with aspect ratios of 0.75 and 1.0, respectively. Shear sliding was limited to approximately 10% of total lateral displacement, prior to the onset of strength degradation, indicating no premature failure caused by this mechanism. The deformation components indicate that flexure and shear were equally important in these walls, and formed approximately 80% of total lateral displacement. A new analysis procedure was developed as part of the analytical investigation. The procedure can be used for strength and deformation computations for low-rise shear walls with aspect ratios of 1.0 or less. It is based on equilibrium, compatibility, and material models. Potential failure planes are first identified and analyses of wall sections are carried out. One of the potential failure planes is the horizontal wall section at the base, and is critical against flexure. A standard plane section analysis is conducted at this section. The compression region determined from the plane section analysis is used to establish the second failure plane, which is inclined towards the loading corner. An inclined section analysis is conducted along this section based on experimentally observed strain variation. Diagonal compression in inclined concrete strut is checked against crushing. The strain condition computed from the inclined section analysis provide sufficient information to establish shear force-shear deformation relationship. The analysis procedure has been verified extensively against available test data. The analytical approach was simplified for use in design. A design procedure is recommended for low-rise shear walls with aspect ratios of 1.0 or less.

description: В статье представлены результаты исследования важнейших проблем музыкального образования и воспитания. Проанализированы исследования, связанные с интонационной основой целостной подготовки музыканта, терминологические и смысловые подходы к составным элементам интонирования – артикулированию, произношению, исполнительским средствам выразительности. Показаны многовариантные возможности процесса длительной многоступенчатой подготовки музыканта-исполнителя, когда на основе интонационных факторов происходит формирование адаптационных возможностей человека к восприятию, осмыслению, переработке и передаче музыкального материала. Одновременно у обучающегося воспитывается культура передачи информации посредством подготовки его интонационных и, шире, музыкально-исполнительских качеств. Эти качества определяют возможности интонирования как процесса эмоционального раскрытия интерпретаторского смысла посредством артикуляционно-штриховых решений, способов звукоизвлечения, динамических градаций, тембровой окраски, темпа, агогики. Обучающийся наполняет свой тезаурус средствами передачи музыкальной информации во всём многообразии современных достижений музыкального искусства, педагогики, психологии и смежных наук. В процессе артикуляционно-штрихового, интонационно обоснованного образовательного процесса воспитывается психофизическая направленность музыканта-исполнителя и культуры его личности.

description: We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the Hubble Space Telescope/ACS Coma Treasury Survey. Parameters from Sersic fits to the two-dimensional surface brightness distributions are given for all galaxies from our published Coma photometric catalogue with mean effective surface brightness brighter than 26.0 mag arcsec-2 and brighter than 24.5 mag (equivalent to absolute magnitude -10.5), as given by the fits, all in F814W(AB). The sample comprises a mixture of Coma members and background objects; 424 galaxies have redshifts and of these 163 are confirmed members. The fits were carried out using both the gim2d and galfit codes. We provide the following parameters: galaxy ID, RA, Dec., the total corrected automatic magnitude from the photometric catalogue, the total magnitude of the model (F814W(AB)), the geometric mean effective radius R-e, the mean surface brightness within the effective radius <>(e), the Sersic index n, the ellipticity and the source position angle. The selection limits of the catalogue and the errors listed for the Sersic parameters come from extensive simulations of the fitting process using synthetic galaxy models. The agreement between gim2d and galfit parameters is sensitive to details of the fitting procedure; for the settings employed here the agreement is excellent over the range of parameters covered in the catalogue. We define and present two goodness-of-fit indices which quantify the degree to which the image can be approximated by a Sersic model with concentric, coaxial elliptical isophotes; such indices may be used to objectively select galaxies with more complex structures such as bulge-disc, bars or nuclear components. We make the catalogue available in electronic format at astro-wise and MAST.
