Effects of salinity and photoperiod on growth, aerobic scope, and hypoxia tolerance of Atlantic and coho salmon in recirculating aquaculture systems
Creators: name: Fang, Yuanchang
Publisher: name: University of British Columbia
Year: 2018

description: Recirculating aquaculture systems (RAS) are an emerging technique in aquaculture to rear salmon in land-based facilities, but the systems are also associated with high costs, so rearing fish under optimal conditions for maximum growth is required for profitability. However, few systematic studies have been conducted to determine optimal conditions for growth of salmon from smolt through to market size in RAS and the related effects on physiological performance. To address this knowledge gap, the first part of my thesis investigated the effect of salinity on growth, metabolism and hypoxia tolerance of Atlantic and coho salmon. Smolts were reared at salinities of 0, 5, 10, 20 and 30 ppt under 24 h of light in RAS for up to 460 days. Between Days 200 and 400, respirometry was conducted to measure routine, maximum metabolic rate and aerobic scope, while time to loss of equilibrium at 10% air saturation was measured to determine hypoxia tolerance. The initial effect of salinity on growth was found in Atlantic and coho salmon at Day 295 and 59, respectively, after which growth was generally enhanced at intermediate salinities of 5 and 10 ppt. No clear relationship was found between salinity and metabolic measurements in either species. Hypoxia tolerance of Atlantic salmon was enhanced at 5 and 10 ppt, but salinity had no effect on hypoxia tolerance of coho salmon. The second part of this thesis aimed to (1) determine metabolism and hypoxia tolerance of coho salmon during their early growth stages where the effect of salinity on growth was the most profound and (2) explore the interactive effect of photoperiod. A new cohort of coho salmon smolts were reared in RAS at 2.5, 5, 10 and 30 ppt under 12:12 and 24:0 (light:dark) photoperiods, while respirometry and hypoxia trials (15% air saturation) were conducted at Day 60 and 120. No effect of salinity and photoperiod was found on metabolic measurements and hypoxia tolerance in the younger coho salmon during these periods. Overall, my data suggest that there is some potential to enhance growth of salmon by manipulating environmental conditions in RAS without compromising other physiological performance.

description: The quantum $H_4$ integrable system is a 4D system with rational potential related to the non-crystallographic root system $H_4$ with 600-cell symmetry. It is shown that the gauge-rotated $H_4$ Hamiltonian as well as one of the integrals, when written in terms of the invariants of the Coxeter group $H_4$, is in algebraic form: it has polynomial coefficients in front of derivatives. Any eigenfunctions is a polynomial multiplied by ground-state function (factorization property). Spectra corresponds to one of the anisotropic harmonic oscillator. The Hamiltonian has infinitely-many finite-dimensional invariant subspaces in polynomials, they form the infinite flag with the characteristic vector $\vec \al\ =\ (1,5,8,12)$.

description: The Chandra Orion Ultradeep Project observed hundreds of young, low-mass stars undergoing highly energetic X-ray flare events. The 32 most powerful cases have been modeled with the result that the magnetic structures responsible for these flares can be many stellar radii in extent. In this paper, we model the observed spectral energy distributions of these 32 stars in order to determine, in detail for each star, whether there is circumstellar disk material situated in sufficient proximity to the stellar surface for interaction with the large magnetic loops inferred from the observed X-ray flares. Our spectral energy distributions span the wavelength range 0.3-8 um (plus 24 um for some stars), allowing us to constrain the presence of dusty circumstellar material out to >10 AU from the stellar surface in most cases. For 24 of the 32 stars in our sample the available data are sufficient to constrain the location of the inner edge of the dusty disks. Six of these (25%) have spectral energy distributions consistent with inner disks within reach of the observed magnetic loops. Another four stars may have gas disks interior to the dust disk and extending within reach of the magnetic loops, but we cannot confirm this with the available data. The remaining 14 stars (58%) appear to have no significant disk material within reach of the large flaring loops. Thus, up to ~40% of the sample stars exhibit energetic X-ray flares that possibly arise from a magnetic star-disk interaction, and the remainder are evidently associated with extremely large, free-standing magnetic loops anchored only to the stellar surface.

description: Optically transparent, colorless Al-O-N and Al-Si-O-N coatings with discretely varied O and Si contents were fabricated by reactive direct current magnetron sputtering (R-DCMS) from elemental Al and Si targets and O2 and N2 reactive gases. The Si/Al content was adjusted through the electrical power on the Si and Al targets, while the O/N content was controlled through the O2 flow piped to the substrate in addition to the N2 flow at the targets. The structure and morphology of the coatings were studied by X-ray diffraction (XRD) and transmission electron microscopy (TEM), while the elemental composition was obtained from Rutherford backscattering spectrometry (RBS) and heavy ion elastic recoil detection analysis (ERDA). The chemical states of the elements in the coatings were analyzed by X-ray photoelectron spectroscopy (XPS). Based on analytical results, a model describing the microstructural evolution of the Al-O-N and also previously studied Al-Si-N [1, 2, 3, 4] coatings with O and Si content, respectively, is established. The universality of the microstructural evolution of these coatings with the concentration of the added element is attributed to the extra valence electron (e–) that must be incorporated into the AlN wurtzite host lattice. In the case of Al-O-N, this additional valence charge arises from the e – acceptor O replacing N in the AlN wurtzite lattice, while the e – donor Si substituting Al fulfills that role in the Al-Si-N system. In view of future applications of ternary Al-O-N and quaternary Al-Si-O-N transparent protective coatings, their mechanical properties such as residual stress (σ), hardness (HD) and Young’s modulus (E) were obtained from the curvature of films deposited onto thin substrates and by nanoindentation, respectively. Moderate compressive stress levels between −0.2 and −0.5 GPa, which suppress crack formation and film-substrate delamination, could be obtained together with HD values around 25 GPa.

description: Time-resolved photoluminescence is applied to determine an effective lifetime of minority charge carriers in semiconductors. Such effective lifetimes include recombination channels in the bulk as well as at the surfaces and interfaces of the device. In the case of Cu(In,Ga)Se2 absorbers used for solar cell applications, trapping of minority carriers has also been reported to impact the effective minority carrier lifetime. Trapping can be indicated by an increased the temperature dependence of the experimentally determined photoluminescence (PL) decay time when compared the temperature dependence of Shockley-Read-Hall recombination alone and can lead to an overestimation of the minority carrier lifetime. Here, it is shown by technology computer aided design (TCAD) simulations and by experiment that the intentional double graded bandgap profile of high efficiency Cu(In,Ga)Se2 absorbers causes a temperature dependence of the PL decay time similar to trapping in case of a recombinative front surface. It is demonstrated that a passivated front surface results in a temperature dependence of the decay time that can be explained without minority carrier trapping and thus enables the assessment of the absorber quality by means of the minority carrier lifetime. Comparison with the absolute PL yield and the quasi Fermi level splitting corroborate the conclusion that the measured decay time corresponds to the bulk minority carrier lifetime of 250 ns for the double graded CIGS absorber under investigation.

description: Using a one-dimensional jellium model and standard beam theory we calculate the spring constant of a vibrating nanowire cantilever. By using the asymptotic energy eigenvalues of the standing electron waves over the nanometer-sized cross-section area, the change in the grand canonical potential is calculated and hence the force and the spring constant. As the wire is bent more electron states fits in its cross section. This has an impact on the spring"constant" which oscillates slightly with the bending of the wire. In this way we obtain an amplitude-dependent resonance frequency of the oscillations that should be detectable.

description: Mit dem Aufkommen der Verlagskartographie im späten 16. Jahrhundert wurden Landkarten als Massenprodukte hergestellt. Sie wurden als Kupferstiche schwarz-weiß gedruckt und danach per Hand koloriert. Doch wie konnte man am besten eine Karte farblich ausgestalten? Dieser Frage geht der Aufsatz nach, indem die Entwicklung der Kolorierungsformen dieser Karten sowohl anhand der schriftlichen Überlieferung in Form von Kolorierungstraktaten als auch unter Berücksichtigung der Landkarten selbst betrachtet wird. Dabei wird aufgezeigt, wie die Kolorierung bis ins 19. Jahrhundert hinein zunehmend methodischer wurde.
description: After the establishment of map printing by publishers in late 16th century, a large amount of maps were printed black and had to be coloured by hand in a second step. The article investigates how the discourses on colouring maps changed from the late 16th to the early 19th century by analysing colouring treatises and hand coloured maps. It demonstrates how the practice of colouring became increasingly systematic and methodical.

description: A series of Rh-based intermetallic compounds supported on silica was prepared and tested in alkene hydrogenation at room temperature. H2 and D2 were used as the hydrogen sources and the kinetic isotope effect (KIE) in hydrogenation was studied. In styrene hydrogenation, the KIE values differed strongly depending on the intermetallic phase, and some intermetallic compounds with Sb and Pb exhibited remarkably high KIE values (>28). An extraordinarily high KIE value of 91, which has never been reported in catalytic reactions at room temperature, was observed particularly for RhPb2/SiO2. RhPb2/SiO2 also showed high KIE values in the hydrogenation of other unsaturated hydrocarbons such as phenylacetylene and cyclohexene. The density functional theory calculation focused on the surface diffusion of hydrogen suggested no contribution of the quantum tunneling effect to the high KIE values observed. A kinetic study revealed that the dissociative adsorption of H2 (D2) was the rate-determining step in the styrene hydrogenation over RhPb2/SiO2. We propose that the large KIE originates from the quantum tunneling occurring at the hydrogen adsorption process with the aid of the specific surface structure of the intermetallic compound and adsorbate alkene.

description: We derive the large deviation function, which provides the large-time full counting statistics for the charge transfer, in the non-equilibrium steady state of the resonant-level model. The general form of this function in free fermion models, in terms of transmission coefficients, was proposed by Levitov and Lesovik in 1993 using a particular measurement set-up involving an interacting spin. It was later suggested to hold as well for a proper quantum mechanical measurement of the transferred charge. We give a precise proof of both statements in the resonant-level model. We first give a full description of the model and its steady state. That is, we explain how the decoupled system prepared with a charge differential evolves, with the impurity coupling, towards the Hershfield non-equilibrium density matrix, in the sense of averages of finitely-supported operators. We describe how this holds both for the usual resonant-level model with a point-like impurity, and for a regularised model with an impurity spread on a finite region, shedding light on subtleties associated to the point-like impurity. We then prove Levitov-Lesovik formula by recasting the problem into calculating averages of finitely-supported operators.

description: In this study, we develop a Na+-sensitive thin-film transistor (TFT) for a biocompatible ion sensor and investigate its cytotoxicity. A transparent amorphous oxide semiconductor composed of amorphous In–Ga–Zn–oxide (a-InGaZnO) is utilized as a channel of the Na+-sensitive TFT, which includes an indium tin oxide (ITO) film as the source and drain electrodes and a Ta2O5 thin-film gate, onto which a Na+-sensitive membrane is coated. As one of the Na+-sensitive membranes, the polyvinyl chloride (PVC) membrane with bis(12-crown-4) as the ionophore used on the TFT sensors shows good sensitivity and selectivity to changes in Na+ concentration but has high cytotoxicity owing to the leaching of its plasticizer to the solution; the plasticizer is added to solve and entrap the ionophore in the PVC membrane. On the other hand, a plasticizer-free Na+-sensitive membrane, the fluoropolysilicone (FPS) membrane with the bis(12-crown-4) ionophore, also reduces cell viability owing to the leaching of the ionophore. However, the FPS membrane with calix[4]arene as the ionophore on the gate of TFT sensors exhibits not only favorable electrical properties but also the lack of cytotoxicity. Thus, considering structural flexibility of TFTs, a platform based on TFT sensors coated with the Na+-sensitive FPS membrane containing calix[4]arene is suitable as a biocompatible Na+ sensing system for the continuous monitoring of ionic components in biological fluids such as sweat and tears.

We present two novel algorithms for searching for a query q in a text s. One solves the decision problem over a binary text in constant time, using a linear size index of the text. The second algorithm, for a general finite alphabet, finds all occurrences of a given Parikh vector q and has sub-linear expected time complexity; we present two variants, which both use a linear size index of the text.

Sulphite treatment to enhance the ethanol production of softwood whole slurries
Creators: name: Zhong, Na
Publisher: name: University of British Columbia
Year: 2018

description: To try to compete with conventional bioethanol production from sugar/starch feedstocks, “whole-slurry”, high solids loading hydrolysis and fermentation of steam pretreated softwood biomass was employed to obtain high sugar, high ethanol concentrations. However, two major challenges were encountered; substrate recalcitrance limiting effective enzymatic hydrolysis and high concentrations of inhibitors inhibiting effective sugar fermentation. The major focus of the work described in this thesis was to assess the benefits of integrating sulphite treatments prior, during and after steam pretreatment to enhance the effectiveness of the enzymatic hydrolysis of the whole cellulose and hemicellulose derived slurry and the fermentation of the biomass derived sugars. Initial work focused on improving fermentation at high sugar concentrations (up to 25% w/v) by improved strain selection, nutrient supplementation and the use of high cell density growth Subsequently, sulphite post treatment was assessed to see if it could improve both the hydrolysis of the whole slurry, containing both cellulose and hemicellulose, and the fermentation of the softwood derived sugars. To try to maximize the beneficial influence of sulphite treatment the softwood chips were treated prior to steam pretreatment, to result in sulphonation ahead of lignin condensation, hopefully improving the extent of sulphonation with less sulphite loading. This approach resulted in some improvements. However, it proved difficult to balance some of the factors that influence the effectiveness of enzyme mediated hydrolysis, such as the extent of suphonation, substrates size reduction and lignin condensation, although an improvement in whole slurry fermentation was observed. To try to further improve this strategy a two stage, alkali- followed by acid-sulphite approach was assessed, using sulphite in the first stage to sulphonate the lignin and SO₂ in the second stage to further sulphonated the lignin while decreasing particle size. This resulted in high degree of sulphonation, enhanced delignification and substantial substrate size reduction. Minimum lignin condensation and fermentation inhibitors were detected. More than 160 g/L fermentable sugars and 80 g/L ethanol could be achieved when using the two stage (alkali and acid) sulphite pretreatment of lodgepole pine approach to generate a hemicellulose and cellulose whole slurry that could be readily hydrolysed and fermented.

description: We develop the first steps towards an analysis of geometry on the quantum spacetime proposed in [1]. The homogeneous elements of the universal differential algebra are naturally identified with operators living in tensor powers of Quantum Spacetime; this allows us to compute their spectra. In particular, we consider operators that can be interpreted as distances, areas, 3- and 4-volumes. The Minkowski distance operator between two independent events is shown to have pure Lebesgue spectrum with infinite multiplicity. The Euclidean distance operator is shown to have spectrum bounded below by a constant of the order of the Planck length. The corresponding statement is proved also for both the space-space and space-time area operators, as well as for the Euclidean length of the vector representing the 3-volume operators. However, the space 3-volume operator (the time component of that vector) is shown to have spectrum equal to the whole complex plane. All these operators are normal, while the distance operators are also selfadjoint. The Lorentz invariant spacetime volume operator, representing the 4- volume spanned by five independent events, is shown to be normal. Its spectrum is pure point with a finite distance (of the order of the fourth power of the Planck length) away from the origin. The mathematical formalism apt to these problems is developed and its relation to a general formulation of Gauge Theories on Quantum Spaces is outlined. As a byproduct, a Hodge Duality between the absolute dif- ferential and the Hochschild boundary is pointed out.

description: The heavy-Fermion liquid with short-range antiferromagnetic correlations is carefully considered in the two-dimensional Kondo-Heisenberg lattice model. As the ratio of the local Heisenberg superexchange $J_{H}$ to the Kondo coupling $J_{K}$ increases, Lifshitz transitions are anticipated, where the topology of the Fermi surface (FS) of the heavy quasiparticles changes from a hole-like circle to four kidney-like pockets centered around $(π,π)$. In-between these two limiting cases, a first-order quantum phase transition is identified at $J_{H}/J_{K}=0.1055$ where a small circle begins to emerge within the large deformed circle. When $J_{H}/J_{K}=0.1425$, the two deformed circles intersect each other and then decompose into four kidney-like Fermi pockets via a second-order quantum phase transition. As $J_{H}/J_{K}$ increases further, the Fermi pockets are shifted along the direction ($π,π$) to ($π/2,π/2$), and the resulting FS is consistent with the FS obtained recently using the quantum Monte Carlo cluster approach to the Kondo lattice system in the presence of the antiferrmagnetic order.

description: Quantitative Structure Activity Relationship (QSAR) is one of the realistic and most successful methods for drug design in optimizing a lead. A series of forty-four molecules from diarylpyrazole benzene sulphonamide derivatives with their cyclooxygenase-2 inhibitory activity were subjected to qsar studies using QSARINS software. The significant two descriptor qsar model generated showed correlation coefficient of cross validation leave one out (Q2LOO)=0.5565, coefficient of determination (R2)=0.6530, (R2ext)=0.8225, cross validation leave many out (Q2LMO)=0.5201, Concordance Correlation Coefficient (CCCcv)=0.7262, CCCtr=0.7901, and CCCext=0.8930. The descriptor 3D Molecular Representations of Structures based on Electronic diffraction (3D-MoRSEC-6) weighted by atomic charges, where 6 is scattering parameter and Geary Autocorrelation-lag3/weighted by atomic Sanderson electronegativities (GATSe3) revealed that the atomic charges and spatial autocorrelation play a key role in Cyclooxygenase-2 inhibitory (COX-2) activity. New lead molecules were designed based on key structural findings and predicted for their COX-2 inhibitory activity using the developed two-descriptor model. Molecular docking studies were carried out for the best-designed molecules using Autodock 4.2.6 along with supportive in silico absorption, distribution, metabolism, excretion, and toxicity predictions. Both the hydrophilic as well as hydrophobic parts of the residues of active site regions interacted with best predicted active compounds. The study suggests crucial properties and key interactions that are essential for potent enzyme inhibition and finds this series as a promising lead for further development as novel cyclooxygenase agents.

description: Context: The minimum number of days needed to measure gas emissions from cattle by using spot sampling methods is the result of the visit frequency, within animal variation and among animal variations.Aims: To estimate (a) the effect of the length of the measurement period on the variation in methane (CH4) and carbon dioxide (CO2) emissions and (b) the number of animals required to detect a difference of 10% between two treatment means for CH4 and CO2.Methods: Gas emissions from 72 dairy cows, supplemented with different concentrate diets, and 72 heifers, weaned at different ages, in two separate experiments, were measured for 3–5 weeks using GreenFeed units. In all four experiments, the animals grazed ryegrass-based pasture. The cows received various concentrate treatments twice daily during milking. The gas emissions in heifers were measured at 280 and 370 days of age. Data from 76 cows and 77 heifers were used in the data analysis. The coefficient of variation (CV) and number of animals required to detect a difference of 10% between the two means were modelled for periods of 3–36 days at 3-day steps.Key results: The CV of CH4 emissions became stable between Days 12 and 18 of measurements in the cows and heifers, respectively (17–37 visits for cows and 43–73 visits for heifers) and then 13–19 cows and 9–11 heifers were required per treatment to detect differences of 10% between means. The CV of CO2 emissions became stable few days earlier than did the CH4 emissions and the variation was smaller.Conclusions: A minimum of 12 and 18 measurement days are recommended to estimate CH4 emission in grazing lactating cows and heifers respectively, and 9–19 animals per treatment were required to detect differences of 10% between means for the conditions of the current studies.Implications: The current analysis has provided information about among-animal variation of gas emissions when performing GreenFeed measurements with grazing cattle, within the experimental conditions of the data sets used for the current study, which can be used to design future cattle studies.

description: We investigate the production of gamma-rays in the inner regions of SS 433 and in its interaction between its jets and the W50 nebula. We estimate the VHE emission that can be generated within the jets at distances above 1e+13 cm from the compact object. We also apply a theoretical model of the jet/medium interaction to SS 433/W50. We compare the predicted fluxes to observations of SS 433 at TeV energies, and derive new constraints of the physical properties of this system.

description: In this paper we define Brownian local time as the almost sure limit of the local times of a nested sequence of simple, symmetric random walks. The limit is jointly continuous in $(t,x)$. The rate of convergence is $n^{\frac14} (\log n)^{\frac34}$ that is close to the best possible. The tools we apply are almost exclusively from elementary probability theory.
