description: NMR-Spektroskopie gehört zu den etabliertesten und leistungsfähigsten Methoden in Chemie und Strukturbiologie, und die Kenntnis der Konstitution, Konfiguration und oft auch der Konformation von Molekülen ist von zentraler Bedeutung für die Entdeckung neuer Wirkstoffe. NMR-Standardparameter wie chemische Verschiebung, 3J-Kopplungskonstanten und NOEs erlauben es, die Mehrzahl der organischen Moleküle strukturell aufzuklären. Verbindungen, die sich einer Strukturaufklärung mit Hilfe dieser Parameter entziehen, lassen sich oft durch Heranziehen komplementärer Parameter wie dipolarer Restkopplungen (RDCs) analysieren. Für die Messung von anisotropen NMR-Parametern werden Orientierungsmedien verwendet wie zum Beispiel mechanisch gespannte Gele, die Anisotropie in der Lösung induzieren. Darüber hinaus sind zur Anpassung der Anisotropie Dehnungsvorrichtungen hilfreich. Für effiziente Messungen von kleinen Probenmengen wurde in dieser Arbeit eine neue Apparatur entwickelt: ausgehend von der vorhandenen 5mm-Dehnungsvorrichtung wurde die Entwicklung einer 3 mm-Dehnungsvorrichtung durchgeführt. Um ebenfalls den Quellschritt des Gels steuern zu können, wurde eine neuartige Quellvorrichtung geschaffen. Die neue Dehnungsvorrichtung wurde in der Praxis getestet und zeigt ermutigende Ergebnisse für die Anpassung der Anisotropie an die passende Stärke. Darüber hinaus wurden Messungen von anisotroper Parametern mit hoher Genauigkeit erreicht. RDCs liefern wertvolle globale-Informationen, zum Beispiel über die Orientierung internuklearer Vektoren innerhalb eines Moleküls. Mit Hilfe von RDCs wurden in der vorliegenden Arbeit die relativen Konfigurationen von Naturstoffen mit mehreren Stereozentren bestimmt, einschließlich der relativen Konfigurationen von tertiären Aminen. Zur Bestimmung der Konfigurationen wurden neben Standardmethoden auch molekular-dynamische Simulationen durchgeführt, in denen experimentelle RDCs als orientierende, tensorielle Randbedingungen verwendet wurden. Die Bestimmung von absoluten Konfigurationen eines Moleküls ist unverzichtbar in der Arzneimittelforschung. Die wichtigste Methode hierzu ist die Röntgenstrukturanalyse, deren Anwendung jedoch durch die Verfügbarkeit eines hochwertigen Kristalls und dem oft hohen Zeitaufwand limitiert ist. Die Entwicklung von weiteren Methoden zur Aufklärung der Stereochemie ist aus diesem Grund ein aktives Forschungsfeld. In dieser Arbeit werden hierzu vorläufige, vielversprechende Daten zur Bestimmung der absoluten Konfiguration von Enantimerenpaare mit Hilfe von RDCs in chiralen Orientierungsmedien präsentiert.

description: Problème En Béarn, le maïs est bien adapté au contexte pédoclimatique, sans perte de potentiel de rendement lorsqu'il est cultivé en monoculture. Mais la pression réglementaire et les risques de volatilité des prix, ainsi que la pression croissante des bio-agresseurs menacent ce système historique. Il est indispensable d'expérimenter des systèmes de culture alternatifs alliant respect de l'environnement, gestion efficace des bio-agresseurs, productivité et rentabilité. Solution En alternative à la monoculture de maïs, une rotation de 2 ans a été mise en place. Elle consiste en une séquence de 3 cultures de rente en 2 ans : maïs, (culture intermédiaire d’avoine et moutarde), soja et avoine CIVE (culture intermédiaire à vocation énergétique). Grâce à l'introduction d’une légumineuse et de couverts, qui permettent de diversifier les cultures tout en bénéficiant d'aides couplées, ce système innovant a montré qu'il améliorait les performances agronomiques, environnementales et économiques.

description: Problem In protected vegetable systems of the Mediterranean area, having bare soil for several weeks in late summer, post cash crop harvest, may induce soil degradation. Providing a soil cover in any period is key to preserve the soil's biological activity and maintain good agronomic conditions (e.g. soil structure) for the following crops. Solution A mixture of Sudan sorghum (Sorghum drummondii), buckwheat (Fagopyrum esculentum) and fodder pea (Pisum sativum subsp. Arvense)can be used as a cover crop at the end of summer under plastic greenhouse systems in the South of France. These species all grow fast and so provide a suitable cover crop in a few weeks. The higher the biomass production the better the crop is at delivering expected benefits.

description: The effect of the wind on the sustain of extreme water waves is investigated experimentally and numerically. A series of experiments conducted in the Large Air-Sea Interactions Facility (LASIF) showed that a wind blowing over a strongly nonlinear short wave group due to the linear focusing of a modulated wave train may increase the life time of the extreme wave event. The expriments suggested that the air flow separation that occurs on the leeward side of the steep crests may sustain longer the maximum of modulation of the focusing-defocusing cycle. Based on a Boundary-Integral Equation Method and a pressure distribution over the steep crests given by the Jeffreys'sheltering theory, similar numerical simulations have confirmed the experimental results

description: In this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed-form relations are derived for mean square error (MSE), mean square deviation (MSD) and excess mean square error (EMSE)of analyzed network in tracking Rayleigh fading channel and random walk model. Comparison between theoretical and simulation results shows a perfect match and verifies performed calculations.
The Effects of residential schools on native child-rearing patterns
Creators: name: Ing, N. Rosalyn
Publisher: name: University of British Columbia
Year: 2012

description: This paper examined the apparent effects of residential schools on the child-rearing patterns of Natives who attended these schools. Evidence came from the literature and from three interviews with persons who attended residential schools -- one male elder and two females, who answered four open-ended questions. The findings suggest that this type of educational experience caused psychological and cultural losses in self-esteem, child-rearing patterns, and Native Indian language. New and different behaviours had.to be learned by the children in middle childhood to cope and exist in a parentless environment where no feelings of love or care were demonstrated by the caretakers and the speaking of Cree and other Native languages was forbidden. Values and skills taught by Native parents/elders, and essential for survival in Native society, lost their importance in residential schools; the Native language was not taught to subsequent generations; and the separation of siblings by sex and age created strangers in families. These experiences will presumably be transmitted in some form to the next generation, thereby affecting the way Natives view themselves. To restore confidence in themselves and respect for essential patterns of child-rearing the process of healing is vital and recommended.

description: In literature the beet is often described as consisting of the following technologically important sections: crown, root and tail. The aim of the study was to determine the distribution of nitrogen compounds in the technologically important beet sections of untopped sugar beets with particular emphasis on the content of nitrate and nitrite. The Finezja sugar beet variety had been collected from the clamps in one of the Polish sugar factories in October during 2013/2014 campaign. The untopped sugar beets were divided into three sections: crown, root and tail. The content of total amount of nitrogen, proteinaceous nitrogen, α-amino nitrogen, the sum of the amide and ammonia nitrogen, nitrates and nitrite in these sections were determined. Although the crown of the sugar beet represented only 14.7% of it mass, this section contained on average 30% of the total quantity of α-amino acids as well as amide and ammonia nitrogen. This section contained approximately 77% of the total quantity of nitrate and 88% of nitrite. Untopped sugar beets would introduce much higher amounts of nitrogen compounds in comparison to topped raw material.

Year: 2016

description: Regardless the form, nickel is an element commonly used. Its numerous advantages make it irreplaceable in many industries. The widespread use of this element in different branches leads to increasing nickel penetration to the environment and its pollution. Furthermore, the contamination of environment results in affecting the living organisms, including both plants that are directly exposed to Ni in soil, water or air, and humans whose exposition to Ni is direct (e.g. contaminated air) and/or indirect (e.g. food with high amount of Ni). Therefore, the exposition of living organisms to Ni may constitute a threat. This paper constitutes the short review of nickel as an environmental contaminant with characterization of its main sources in the environment. The nickel nanoparticles have been also studied. The influence of Ni and its nanoparticles on living organisms with emphasizing its allergenicity of human has been described.

description: The 4,n-alkyloxybenzoic acid 6OBAC has a very rich variety of crystalline structures and two nematic sub-phases, characterised by different textures. It is a material belonging to a family of liquid crystals formed by hydrogen bonded molecules, the 4,n-alkyloxybenzoic acids indicates the homologue number). The homologues with n ranging from 7 to 13 display both smectic C and N phases. In spite of the absence of a smectic phase, 6OBAC exhibits two sub-phases with different textures, as it happens in other materials of the homologue series which possess the smectic phase. This is the first material that exhibits a texture transition in a nematic phase directly originated from a crystal phase. Here we present the results of an image processing assisted optical investigation to characterise the textures and the transitions between textures. This processing is necessary to discriminate between crystal modifications and nematic sub-phases.

description: We study the zero-field optical spin noise spectra (OSN) for a thermal state hot 87Rb vapor with strong spin exchange coupling. Our main findings are: (1) The OSN spectrum consists of two components representing a positive and a negative hyperfine spin correlation (HSC), the relative power of which varies dramatically with the detuning frequency of the probe. (2) There exist two polar frequencies at which the OSN spectrum is completely polarized with one type of HSC. (3) At the limit of far detuning, the power ratio of the positive and negative HSC component of the OSN is 4:5. (4) The total power of the OSN is independent of the strength of SE coupling. (5) We give a simple way of deriving the OSN using the eigensolution of the density matrix equation.

description: We study the mean escape time in a market model with stochastic volatility. The process followed by the volatility is the Cox Ingersoll and Ross process which is widely used to model stock price fluctuations. The market model can be considered as a generalization of the Heston model, where the geometric Brownian motion is replaced by a random walk in the presence of a cubic nonlinearity. We investigate the statistical properties of the escape time of the returns, from a given interval, as a function of the three parameters of the model. We find that the noise can have a stabilizing effect on the system, as long as the global noise is not too high with respect to the effective potential barrier experienced by a fictitious Brownian particle. We compare the probability density function of the return escape times of the model with those obtained from real market data. We find that they fit very well.

Iterative inverse kinematics with manipulator configuration control and proof of convergence
Creators: name: Grudić, Gregory Z.
Publisher: name: University of British Columbia
Year: 2012

description: A complete solution to the inverse kinematics problem for a large class of practical manipulators, which includes manipulators with no closed form inverse kinematics equations, is presented in this thesis. A complete solution to the inverse kinematics problem of a manipulator is defined as a method for obtaining the required joint variable values to establish the desired endpoint position, endpoint orientation, and manipulator configuration; the only requirement being that the desired solution exists. For all manipulator geometries that satisfy a set of conditions (THEOREM I), an algorithm is presented that is theoretically guaranteed to always converge to the desired solution (if it exists). The algorithm is extensively tested on two complex 6 degree of freedom manipulators which have no known closed form inverse kinematics equations. It is shown that the algorithm can be used in real time manipulator control. Applications of the method to other 6 DOF manipulator geometries and to redundant manipulators are discussed.

description: Abridged Abstract - Utilizing the FORS2 instrument on the VLT, we have obtained near infrared spectra for more than 200 stars in 28 populous LMC clusters. This cluster sample spans a large range of ages (~ 1-13 Gyr) and metallicities (-0.3 > [Fe/H] > -2.0) and has good areal coverage of the LMC disk. The strong absorption lines of the Calcium II triplet are used to derive cluster radial velocities and abundances. We determine mean cluster velocities to typically 1.6 km/s and mean metallicities to 0.04 dex (random error). For eight of these clusters, we report the first spectroscopically determined metallicities based on individual cluster stars, and six of these eight have no published radial velocity measurements.

description: We report the properties of a new young double stellar cluster in the region towards IRAS 07141-0920 contained in the HII region Sh2-294. High-resolution optical UBVRI and Halpha images, near-infrared JHKs and H2 filter images were used to make photometric and morphological studies of the point sources and the nebula seen towards Sh2-294. The optical images reveal an emission nebula with very rich morphological details, composed mainly of UV scattered light and of Halpha emission. Contrasting with the bright parts of the nebula, opaque, elongated patches are seen. Our optical photometry confirms that the illuminator of the nebula is likely to be a B0.5V star located at a distance of about 3.2 kpc. Our near-IR images reveal an embedded cluster, extending for about 2 pc and exhibiting sub-clustering: a denser, more condensed, sub-cluster surrounding the optical high-mass B0.5V illuminator star; and a more embedded, optically invisible, sub-cluster located towards the eastern, dark part of the nebula and including the luminous MSX source G224.1880+01.2407, a massive protostellar candidate that could be the origin of jets and extended features seen at 2.12 micron. The double cluster appears to be clearing the remaining molecular material of the parent cloud, creating patches of lower extinction and allowing some of the least reddened members to be detected in the optical images. We find 12 MS and 143 PMS members using 3 different methods: comparison with isochrones in optical colour-magnitude diagrams, detection of near-IR excess, and presence of Halpha emission. The most massive star fits a 4 Myr post-MS isochrone. The age of the optically selected PMS population is estimated to be 7-8 Myr. The IR-excess population shows sub-clustering on scales as small as 0.23 pc and is probably much younger.

description: The increasing market penetration of electric vehicles (EVs) may pose significant electricity demand on power systems. This electricity demand is affected by the inherent uncertainties of EVs' travel behavior that makes forecasting the daily charging demand (CD) very challenging. In this project, we use the National House Hold Survey (NHTS) data to form sequences of trips, and develop machine learning models to predict the parameters of the next trip of the drivers, including trip start time, end time, and distance. These parameters are later used to model the temporal charging behavior of EVs. The simulation results show that the proposed modeling can effectively estimate the daily CD pattern based on travel behavior of EVs, and simple machine learning techniques can forecast the travel parameters with acceptable accuracy.

Proton NMR studies of human lumbar intervertebral discs
Creators: name: Rind, Teresa
Publisher: name: University of British Columbia
Year: 2010

description: Problems with the low back resulting from diseases of the lumbar disc account for much human suffering and medical expense. Through early identification of changes in the disc, Magnetic Resonance Imaging offers a potential method for recognition of those at risk of low back trouble. An understanding of the chemical and structural basis of the MR image will therefore be of great help in understanding the degenerative mechanism itself. With this in mind, NMR studies of human intervertebral discs were performed to extract data that could be correlated with different stages of degeneration. In vitro samples of anulus fibrosus and nucleus pulposus of grades II and IV discs were examined. The Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence was used to obtain T₂ relaxation data, which were analysed with a non-negative least squares algorithm and presented as a continuous spectrum of exponentials. An inversion-recovery sequence was used to obtain T₁ data which were analysed with the same algorithm, then presented as a discrete exponential spectrum. The same procedures were used to produce relaxation times from samples of isolated disc collagen and proteoglycan. Also, T₂ relaxation data were obtained with a twelve-echo CPMG imaging sequence from healthy volunteers, and these data analysed with the same procedure used for in vitro data. In vivo and in vitro results were compared and found to agree in terms of the T₂ relaxation values. Most change between grades occurred in the nucleus, where both T₁ and T₂ values decreased from grade II to grade IV. The results of the proteoglycan and collagen studies support the theory that structure, not chemical composition, is responsible for the observed changes in relaxation times. Based on estimates of the percentages of protons in the nucleus due to water, proteoglycan and collagen, tentative assignments were made to the components of the T₂ spectra for grades II and IV nucleus, and these were supported by the results of all parts of the study.

The precise distribution of the neutron excess has little effect on the form factors of the isotopes though there is a mass dependence in the charge densities. However, the form factors of the proton-rich nucleus, 8B, are significantly changed by the presence of the proton halo.

description: String theory on ${\rm AdS}_3\times {\rm S}^3 \times\mathbb{T}^4$ with one unit ($k=1$) of NS-NS flux is considered in the hybrid formalism of Berkovits, Vafa & Witten (BVW). Using the free field realisation of the world-sheet theory at $k=1$, we identify explicitly the BRST cohomology classes corresponding to some of the low-lying states of the dual CFT. In particular, we do this for the ${\cal N}=4$ superconformal generators of the symmetric orbifold theory, and we confirm these identifications by showing that the worldsheet correlators reproduce the expected dual CFT answer. Along the way we note that the physical vertex operators on the worldsheet have a simpler form if one works with a different, but equivalent, choice for the BRST operators relative to BVW.

With the cumulant expansion method up to the second order, we obtain a relation between the positional order parameter $Ψ$ and the mean square displacement $M$ to be $Ψ\sim \exp(- {\bf K}^2 M /2d)$ with a reciprocal vector ${\bf K}$ and the dimension of the system $d$. On the basis of the relation, the behavior of positional order is predicted to be $Ψ\sim \exp(-{\bf K}^2Dt)$ when the system involves normal diffusion with a diffusion constant $D$. We also find that a diffusion process with swapping positions of particles contributes to higher orders of the cumulants. The swapping diffusion allows particle to diffuse without destroying the positional order while the normal diffusion destroys it.

description: This study examines changes that occur in yeast cell Surface properties during physical, chemical and mechanical treatment and their potential impact on the biomass uptake capacity for lead. As a result of biomass treatment, the negative surface charge decreased and relative hydrophobicity increased. A strong negative correlation was discovered between the negative surface charge of variously modified yeast cells and their relative hydrophobicity. Despite the lower negative surface charge of treated in comparison to untreated yeast cells, the treated biomass had higher lead sorption capability. No relationship was found between the effectiveness of lead sorption by treated biomass and its surface charge or relative hydrophobicity.

description: A Bott tower is the total space of a tower of fibre bundles with base CP^1 and fibres CP^1. Every Bott tower of height n is a smooth projective toric variety whose moment polytope is combinatorially equivalent to an n-cube. A circle action is semifree if it is free on the complement to fixed points. We show that a (quasi)toric manifold (in the sense of Davis-Januszkiewicz) over an n-cube with a semifree circle action and isolated fixed points is a Bott tower. Then we show that every Bott tower obtained in this way is topologically trivial, that is, homeomorphic to a product of 2-spheres. This extends a recent result of Ilinskii, who showed that a smooth compact toric variety with a semifree circle action and isolated fixed points is homeomorphic to a product of 2-spheres, and makes a further step towards our understanding of a problem motivated by Hattori's work on semifree circle actions. Finally, we show that if the cohomology ring of a quasitoric manifold (or Bott tower) is isomorphic to that of a product of 2-spheres, then the manifold is homeomorphic to the product.

description: We map the glacial geomorphology of the former Patagonian Ice Sheet between 44°S and 46°S. Building on previous work, our map covers a ∼50,000 km2 region of west-central Patagonia. The study area includes the eastward-flowing Río Pico, Río Caceres, Río Cisnes, Lago Plata-Fontana, El Toqui, Lago Coyt/Río Ñirehuao, Simpson/Paso Coyhaique, and Balmaceda palaeo-outlet glaciers, adjacent valleys, and the Andean Cordillera. The inventory contains >70,000 individual landforms mapped from remotely-sensed imagery and field surveys. Mapping was classified into ice-marginal (e.g. moraine ridges, trimlines), subglacial (e.g. glacial lineations, flutes), glaciolacustrine (e.g. palaeolake shorelines, perched deltas), glaciofluvial (e.g. proglacial outwash plains, meltwater channels), and non-glacial (e.g. palaeochannels, landslides or slumps) landform groups. The new map will inform future interpretations of regional glacier dynamics, and the development of robust geochronological datasets that test the timing of glaciation and deglaciation.
On unifying the laws of sensation : an empirical investigation of predictions arising from Norwich's theory of perception
Creators: name: Davidson, Kelly Patricia
Publisher: name: University of British Columbia
Year: 2010

description: The present thesis constitutes an empirical investigation of the prediction of Norwich's Entropy Theory of Perception that the positive exponent of the magnitude estimation power function and the negative exponents of equations relating the Weber fraction and simple reaction time to stimulus intensity should, since they can all be derived from the theory's Fundamental Equation, be numerically the same. A pilot study consisting of magnitude estimation and reaction time experiments (using pure tone auditory stimuli of varying intensities at five frequencies), and a "main" study comprised of magnitude estimation, reaction time, and Weber fraction experiments are described. The results, while offering possible confirmation of the prediction, remain somewhat tentative, owing to the persistently problematic technique of curve fitting upon which determination of the reaction time and Weber fraction exponents rests. The theory, in leading one to even attempt to compare such previously unrelated measures as magnitude estimation and reaction time with Weber fractions, has yielded, theoretical issues aside, some worthwhile empirical results: I have obtained measures on three different psychophysical tasks from the same subjects over (effectively) the same stimulus range for each of those subjects; and, moreover have, I believe for the first time, explicitly noted that the Weber fraction displays the same decrease in exponent with increasing frequency, followed by an upturn at the highest frequencies, that characterizes both the equal loudness curves and the reaction time curves a la Chocholle. Suggestions are made regarding supplementary curve fitting methods by which to analyze these data, as well as for future research in the psychophysiological realm which, in addition to expanding the scope of the prediction that is being tested, may provide some much needed insight into the numerical values of the multiplicative and additive constants that occur in the equations under consideration in this thesis.

description: The incompressible Navier-Stokes equations are solved in a channel, using a Discontinuous Galerkin method over staggered grids. The resulting linear systems are studied both in terms of the structure and in terms of the spectral features of the related coefficient matrices. In fact, the resulting matrices are of block type, each block showing Toeplitz-like, band, and tensor structure at the same time. Using this rich matrix-theoretic information and the Toeplitz, Generalized Locally Toeplitz technology, a quite complete spectral analysis is presented, with the target of designing and analyzing fast iterative solvers for the associated large linear systems. Quite promising numerical results are presented, commented, and critically discussed for elongated two- and three-dimensional geometries.

Effect of free fatty acids and dichloroacetic acid on the diabetic isolated working rat heart

Publisher: name: University of British Columbia

description: It is well established that a cardiomyopathy independent of atherosclerosis develops in both humans and animals with diabetes mellitus. The etiology of diabetic cardiomyopathy is very complex involving many different processes, one of which may be the increased fatty acid utilization, and/or the concomitant decrease in glucose utilization, by the diabetic heart. We compared control and 6-week streptozotocin(STZ)-induced diabetic isolated working rat hearts and were able to demonstrate cardiac dysfunction in the diabetic as assessed by depressed heart rate (HR), heart rate peak systolic pressure product (HR X PSP), left ventricular developed pressure (LVDP), rate of pressure rise (+dP/dt) and rate of pressure decline (-dP/dt). Paralleling depressed cardiac function in the diabetic were hyperglycemia, hyperlipidemia and decreased body weight gain as compared to age-matched controls. The addition of free fatty acids, in the form of 1.2 mM palmitate, to the isolated working heart perfusate had no effect on either control or diabetic heart function, with the exception of a depressive effect on +dP/dt of diabetic hearts and -dP/dt of control hearts. But, diabetic hearts perfused with palmitate-containing perfusate plus the glucose oxidation stimulator dichloroacetate (DCA) showed a marked improvement in function. Heart rate, HR X PSP, LVDP and +/-dP/dt were all restored to control heart values in diabetic hearts perfused in the presence of DCA. Creatine phosphate and adenosine 5'-triphosphate (ATP) levels were similar under all perfusion conditions, therefore eliminating energy stores as the limiting factor in heart function. Results indicate that DCA-induced stimulation of glucose oxidation acutely reversed diabetic cardiac function depression. Therefore, depression of glucose oxidation in the diabetic heart may be contributing to diabetic cardiomyopathy.
