description: The mineral magnetic properties of Pleistocene aeolian dune sands from the island of Fuerteventura (Canary Islands, Spain) were studied in order to reconstruct the palaeoenvironmental evolution of Pleistocene climates during their formation. The palaeodunes on Fuerteventura mainly consist of carbonate sands admixed with dust and material of volcanic origin. Due to the low magnetic background caused by the diamagnetic character of carbonate sands, these archives offer a lot of potential for environmental magnetic studies to detect the imprint of dust, volcanic material and paedogenesis. Four sections of alternating palaeosurface–aeolianite sequences in palaeodune fields have been analysed by means of extensive rock magnetic measurements. These Quaternary archives consist of deposits originating from different sources. I. material blown from the shallow shelf, II. material of volcanic origin, and III. long-range transported dust. The rock magnetic findings enable a more detailed interpretation of the palaeosurfaces within the sequences. We are able to differentiate semiquantitatively between the different source materials on one hand and to distinguish on the other hand those from soil-forming processes. Soil formation is only weakly developed in the dust imprints in the palaeosol aeolianite sequences, linked to sparse vegetation cover during the Pleistocene on Fuerteventura.

description: Massive stars influence the surrounding universe far out of proportion to their numbers through ionizing radiation, supernova explosions, and heavy element production. Their formation requires the collapse of massive interstellar gas clouds with very high accretion rates. We discuss results from the first three-dimensional simulations of the gravitational collapse of a massive, rotating molecular cloud core that include heating by both non-ionizing and ionizing radiation. Local gravitational instabilities in the accretion flow lead to the build-up of a small cluster of stars. These lower-mass companions subsequently compete with the high-mass star for the same common gas reservoir and limit its overall mass growth. This process is called fragmentation-induced starvation, and explains why massive stars are usually found as members of high-order stellar systems. These simulations also show that the HII regions forming around massive stars are initially trapped by the infalling gas, but soon begin to fluctuate rapidly. Over time, the same ultracompact HII region can expand anisotropically, contract again, and take on any of the observed morphological classes. The total lifetime of HII regions is given by the global accretion timescale, rather than their short internal sound-crossing time. This solves the so-called lifetime problem of ultracompact HII region. We conclude that the the most significant differences between the formation of low-mass and high-mass stars are all explained as the result of rapid accretion within a dense, gravitationally unstable flow.

description: La scelta del tema per questo lavoro di tesi è nata dall’osservazione di un clima di classe che ostacolava l’apprendimento. Durante le lezioni, infatti, occorreva interrompere il lavoro per riprendere le regole collettive, facendo riflettere i bambini sulla situazione e riportando così un clima più adeguato. All’interno della classe, vi erano anche due alunni con una grande necessità di ricevere attenzioni. Per questo motivo, presentavano atteggiamenti inopportuni che non permettevano al gruppo di proseguire serenamente nell’attività. Lo scopo del mio intervento è stato quello di riportare un clima di lavoro favorevole all’apprendimento e la serenità all’interno dell’aula. Ho quindi proposto un itinerario che permettesse agli allievi di conoscersi reciprocamente, con l’obiettivo di favorire e sviluppare delle relazioni e dinamiche positive, favorire un’identità di gruppo e la collaborazione tra coetanei. Analizzando i dati raccolti a seguito della ricerca qualitativa, ho potuto notare che le diverse attività proposte hanno portato a un beneficio all’interno della classe. Tra i bambini si sono sviluppate delle dinamiche e relazioni positive, si è rafforzata l’identità di gruppo, e ho potuto osservare un clima di lavoro più sereno. La collaborazione tra pari non è stata sviluppata come programmato, in quanto, a causa di una mancata condivisione da parte della docente titolare, non è stato possibile trasporla anche nelle altre materie scolastiche.
A Progenitor for the Extremely Luminous Type Ic Supernova 2007bi

description: SN 2007bi is an extremely luminous Type Ic supernova. This supernova is thought to be evolved from a very massive star, and two possibilities have been proposed for the explosion mechanism. One possibility is a pair-instability supernova with an M_{CO} ~ 100 M_sun CO core progenitor. Another possibility is a core-collapse supernova with M_{CO} ~ 40 M_sun. We investigate the evolution of very massive stars with main-sequence mass M_{MS} = 100 - 500 M_sun and Z_0 = 0.004, which is in the metallicity range of the host galaxy of SN 2007bi, to constrain the progenitor of SN 2007bi. The supernova type relating to the surface He abundance is also discussed. The main-sequence mass of the progenitor exploding as a pair-instability supernova could be M_{MS} ~ 515 - 575 M_sun. The minimum main-sequence mass could be 310 M_sun when uncertainties in the mass-loss rate are considered. A star with M_{MS} ~ 110 - 280 M_sun evolves to a CO star, appropriate for the core-collapse supernova of SN 2007bi. Arguments based on the probability of pair-instability and core-collapse supernovae favour the hypothesis that SN 2007bi originated from a core-collapse supernova event.

description: The Denmark Strait overflow is the major export route of dense water from the Arctic Mediterranean into the North Atlantic. At the Strait's shallow sill, the overflow is a bottom-intensified cold and dense plume, bound to the east by a thermal front formed with the warmer, northward flowing North Icelandic Irminger Current. More than two decades of observations at the sill show strong fluctuations of volume flux on daily time scales. To better understand the source of this variability, a five-mooring array was installed at the sill, capturing nearly 1 year of velocity and bottom temperature measurements at a high temporal and spatial resolution. Bottom temperature fluctuations that exceed 4 °C indicate a meandering of the front between the plume and the North Icelandic Irminger Current. Current vector rotation shows trains of alternating cyclones and anticyclones at the sill. An eddy crosses the sill every 3 to 6 days with a mean velocity of 0.4 m/s and a typical diameter of 30 to 40 km. The results suggest that anticyclones, with centers passing through the deepest part of the sill, may be responsible for periods of increased volume flux—also referred to as boluses and pulses in previous studies. Although the relationship between eddies, pulses, and boluses is still unclear, the results show that eddies are directly linked to fluctuations in the strength, thickness, and position of the overflow plume.

description: The upgrade for ATLAS detector will undergo different phase towards super-LHC. The first upgrade for the Pixel detector will consist of the construction of a new pixel layer which will be installed during the first shutdown of the LHC machine (LHC phase-I upgrade). The new detector, called Insertable B-Layer (IBL), will be inserted between the existing pixel detector and a new (smaller radius) beam-pipe at a radius of 3.3 cm. The IBL will require the development of several new technologies to cope with increase of radiation or pixel occupancy and also to improve the physics performance which will be achieved by reducing the pixel size and of the material budget. Three different promising sensor technologies (planar-Si, 3D-Si and diamond) are currently under investigation for the pixel detector. An overview of the project with particular emphasis on pixel module is presented in this paper.

description: The aim of the work is the calculation and design of an automobile gasoline engine with a capacity of 80 kW.
In the course of the work, the following were calculated: the engine workflow according to the Grinevetsky-Masing method, the forces and moments that arise in the engine elements, the balance was also analyzed, and the strength of the crankshaft, connecting rod and piston pin of the engine was calculated. Based on the calculations, longitudinal and transverse sections of the engine are developed.
The results of the work can be applied in the domestic automotive and engine industries. The developed engine is designed for installation on small class cars, which are the most common in the Russian Federation.
Thus, as a result of the work, a calculation was made and the design of an automobile gasoline engine with a capacity of 80 kW was worked out.

description: Abstract Transforming biomass based compounds with renewable electrical energy into products presents a promising approach towards development of a circular economy. Herein, 5-hydroxymethylfurfural (HMF), derivable from cellulose and hemicellulose, is successfully electrochemically converted into 2,5-furandicarboxylic acid (FDCA). The reactions are performed in alkaline aqueous solutions using commercial nickel oxide (NiO) or a mesostructured nickel oxide derived by CMK-1 templating (NiO-CMK-1). Both catalytic activity and the selectivity of FDCA are highly dependent on the catalyst structure. NiO-CMK-1 facilitates multiple times higher FDCA selectivity (>80%) compared with commercial NiO (30%). Electrochemical analyses emphasize a net-current density for NiO of 2 mA cm−2 whereas for NiO-CMK-1 the net-current density increases significantly to above 4 mA cm−2. The exposed material surface and structure of the catalysts are analyzed via nitrogen physisorption and powder X-ray diffraction revealing that both NiO and NiO-CMK-1 possess a face-centered cubic crystal structure but distinctly different exposed surface areas. Since NiO-CMK-1 enables remarkably improved catalytic activity for the oxidation of HMF, a recycling study is conducted with five consecutive catalytic cycles emphasizing the technological potential of this approach.

description: We consider the problem of soft gluon resummation for gauge theory amplitudes and cross sections, at next-to-eikonal order, using a Feynman diagram approach. At the amplitude level, we prove exponentiation for the set of factorizable contributions, and construct effective Feynman rules which can be used to compute next-to-eikonal emissions directly in the logarithm of the amplitude, finding agreement with earlier results obtained using path-integral methods. For cross sections, we also consider sub-eikonal corrections to the phase space for multiple soft-gluon emissions, which contribute to next-to-eikonal logarithms. To clarify the discussion, we examine a class of log(1 - x) terms in the Drell-Yan cross-section up to two loops. Our results are the first steps towards a systematic generalization of threshold resummations to next-to-leading power in the threshold expansion.

description: In questa tesi si vuole indagare lo sviluppo delle convinzioni degli allievi riguardo alle fasi e agli elementi salienti del processo descrittivo di un procedimento matematico, così come l’evoluzione delle prestazioni degli allievi relativa a questo atto comunicativo. Durante un’attività introduttiva si sono raccolte le convinzioni iniziali degli allievi circa le fasi e gli elementi salienti del processo descrittivo, che sono state poi messe a confronto con le convinzioni finali ricavate attraverso un questionario al termine del percorso sperimentato, in cui si è mirato a focalizzare e sviluppare gli elementi implicati nel processo descrittivo. Un’analisi qualitativa delle produzioni degli allievi durante le varie attività ha permesso di osservare l’evoluzione delle prestazioni durante il percorso. I risultati ottenuti mostrano che gli allievi hanno sviluppato una maggiore consapevolezza per quanto riguarda gli aspetti coinvolti nella descrizione di un procedimento matematico, cosa che ha permesso loro di acquisire e consolidare le proprie compentenze e di produrre delle descrizioni ben strutturate ed esaustive, ricche di termini specifici della matematica e di elementi esplicativi, anche in un’ottica di sviluppo di competenze argomentative.

A Correlation Between the Ionization State of the Inner Accretion Disk and the Eddington Ratio of Active Galactic Nuclei

description: X-ray reflection features observed from the innermost regions of accretion disks in Active Galactic Nuclei (AGNs) allow important tests of accretion theory. In recent years it has been possible to use the Fe K line and reflection continuum to parametrize the ionization state of the irradiated inner accretion disk. Here, we collect 10 measurements of xi, the disk ionization parameter, from 8 AGNs with strong evidence for reflection from the inner accretion disk and good black hole mass estimates. We find strong statistical evidence (98.56% confidence) for a nearly linear correlation between xi and the AGN Eddington ratio. Moreover, such a correlation is predicted by a simple application of alpha-disk accretion theory, albeit with a stronger dependence on the Eddington ratio. The theory shows that there will be intrinsic scatter to any correlation as a result of different black hole spins and radii of reflection. There are several possibilities to soften the predicted dependence on the Eddington ratio to allow a closer agreement with the observed correlation, but the current data does not allow for an unique explanation. The correlation can be used to estimate that MCG-6-30-15 should have a highly ionized inner accretion disk, which would imply a black hole spin of ~0.8. Additional measurements of xi from a larger sample of AGNs are needed to confirm the existence of this correlation, and will allow investigation of the accretion disk/corona interaction in the inner regions of accretion disks.

description: The goal of the Genome3D project is to provide predicted macromolecular structures for hundreds of thousands structurally uncharacterised protein sequences and it is designed to help biologists exploit structural data to understand protein functions. InterPro provides functional analysis of proteins by classifying them into families, predicting domains, repeats and important sites. The Protein Data Bank in Europe (PDBe) manages the worldwide macromolecular structure archive for the Protein Data Bank (PDB).

As part of the project InterPro, together with the Protein Data Bank in Europe (PDBe), have developed mechanisms to display structural data in a way which will allow biologists to view sequence features such as conserved residues, in a structural context. The residue conservation scores are obtained by performing multiple alignments against the UniprotKB database using HMMER tools. Eventually, when the pattern of amino acid conservation is overlaid upon a structure, the often-disparate regions of high conservation may be brought together to form ‘hot spots’ of conservation indicating a functionally important region, such as a ligand binding site.

Evaluation of the grapevine red blotch virus epidemiological landscape of the Okanagan valley
Creators: name: Kahl, Dieter
Publisher: name: University of British Columbia
Year: 2021

description: The first data chapter of this research presents a novel approach for identifying potential insect vectors of circulative plant viruses, significantly reducing time-to-results and the resource costs associated with greenhouse transmission experiments. This artificial transmission protocol using a buffered sucrose solution as the virus recipient in place of a living plant, also eliminates plant-to-plant variation in susceptibility to infection, allowing assessment of virus-insect compatibility required for successful transmission of persistent viruses. To validate this approach, species of hemipteran insects, including leafhoppers, froghoppers, aphids, sharpshooters, and treehoppers, were subjected to the artificial feeding system to determine their ability to vector Grapevine red blotch virus (GRBV). Test insects were allowed to feed on a potted grapevine infected with GRBV for three days and then transferred to tubes containing the sucrose solution partitioned by a thinly stretched Parafilm membrane. After three days of feeding through the membrane, viruliferous test insects were stored for species identification and the sucrose solutions were tested by polymerase chain reaction for the presence of GRBV DNA. Of all the insects tested (n = 393), only nine treehoppers from two different species successfully transmitted GRBV to the sucrose solutions, indicating a high-likelihood of vector capability to plants, to be validated by greenhouse or field experiments. The second data chapter presents research that investigated GRBV titres from several grapevine tissues, including roots, buds, cortical scrapings, and leaves, at varying distances from the cordons, and at different times during the growing season and winter dormancy. Two common nucleic acid extraction techniques were compared, a low cost high-throughput nucleic acid extraction method (GES) and a DNA column purification method. Ideal combinations of sampling parameters were determined for summer and winter diagnostics. In dormant samples, cortical scrapings yielded the highest GRBV titres and produced no false-negatives, and basal leaves yielded high GRBV titres throughout the summer months with only one false-negative on the earliest sample date. These two tissues provide the best samples for reliable and reproducible GRBV diagnostics. The crude GES and DNA column purification methods performed comparably well for binary diagnostics, however the GES method performed poorly in quantitative analysis.

Year: 2019

description: A survey was administered to assess overall expectations of administrators, teachers, families, and students with mild, moderate, and severe intellectual disabilities (ID) ranging in age from 14 to 21. Survey questions assessed expectations regarding paid jobs after school, wages, obtaining a regular high school diploma, getting a driverâs license, living away from home, and attending postsecondary education. The survey was completed online or returned by mail. A total of 2,015 surveys were sent to four school districts with a 33.6% (n=677) response rate. This survey analysis focused more specifically on student and family expectations. Major findings indicated student expectations were higher than family expectations especially in postsecondary education.

Year: 2019

description: Many students with intellectual and developmental disabilities (IDD) enrolled in postsecondary education do not derive full benefits of attending college because of their limited academic skills. This review summarizes a series of experimental studies that investigated the effects of interventions that targeted reading and writing skills for young adults with IDD enrolled in an authentic postsecondary education setting. Results of the review suggest that young adults with IDD can benefit from explicit instruction and cognitive strategy instruction. Effective academic intervention should be adaptive to the diverse learning needs of the students while providing a scaffold that supports their motivation and their persistence.

Spinning branes in Riemann-Cartan spacetime

Year: 2010

description: We use the conservation law of the stress-energy and spin tensors to study the motion of massive brane-like objects in Riemann-Cartan geometry. The world-sheet equations and boundary conditions are obtained in a manifestly covariant form. In the particle case, the resultant world-line equations turn out to exhibit a novel spin-curvature coupling. In particular, the spin of a zero-size particle does not couple to the background curvature. In the string case, the world-sheet dynamics is studied for some special choices of spin and torsion. As a result, the known coupling to the Kalb-Ramond antisymmetric external field is obtained. Geometrically, the Kalb-Ramond field has been recognized as a part of the torsion itself, rather than the torsion potential.
Size-Dependent Cellular Uptake of RGD Peptides

Year: 2019

description: Abstract Monomeric RGD peptides show unspecific fluid-phase uptake in cells, whereas multimeric RGD peptides are thought to be internalized by integrin-mediated endocytosis. However, a potential correlation between uptake mechanism and molecular mass has been neglected so far. A dual derivatization of peptide c(RGDw(7Br)K) was performed to investigate this. A fluorescent probe was installed by chemoselective Suzuki–Miyaura cross-coupling of the 7-bromotryptophan and a poly(ethylene glycol) (PEG) linker was attached to the lysine residue. Flow cytometry and live cell imaging confirmed unspecific uptake of the small, non-PEGylated peptide, whereas the PEG5000 peptide conjugate unveiled a selective internalization by M21 cells overexpressing αvβ3 and no uptake in αv-deficient M21L cells.
Constraints on two-neutron separation energy in the Borromean $^{22}$C nucleus

description: The recently extracted matter radius of carbon isotope $^{22}$C allows us to estimate the mean-square distance of a halo neutron with respect to the center-of-mass of this nucleus. By considering this information, we suggest an energy region for an experimental investigation of the unbound $^{21}$C virtual state. Our analysis, in a renormalized zero-ranged three-body model, also indicates that the two-neutron separation energy in $^{22}$C is expected to be found below $\sim$0.4~MeV, where the $^{22}$C is approximated by a Borromean configuration with a pointlike $^{20}$C and two $s$-wave halo neutrons. A virtual-state energy of $^{21}$C close to zero, would make the $^{22}$C, within Borromean nuclei configurations, the most promising candidate to present an excited bound Efimov state or a continuum three-body resonance.

description: Covalent triazine frameworks (CTFs) are a class of porous organic polymers that continuously attract growing interest because of their outstanding chemical and physical properties. However, the control of extended porous organic framework structures at the molecular scale for a precise adjustment of their properties has hardly been achieved so far. Here, we present a series of bipyridine-based CTFs synthesized through polycondensation, in which the sequence of specific building blocks is well controlled. The reported synthetic strategy allows us to tailor the physicochemical features of the CTF materials, including the nitrogen content, the apparent specific surface area, and optoelectronic properties. Based on a comprehensive analytical investigation, we demonstrate a direct correlation of the CTF bipyridine content with the material features such as the specific surface area, band gap, charge separation, and surface wettability with water. The entirety of these parameters dictates the catalytic activity as demonstrated for the photocatalytic hydrogen evolution reaction (HER). The material with the optimal balance between optoelectronic properties and highest hydrophilicity enables HER production rates of up to 7.2 mmol/(h·g) under visible light irradiation and in the presence of a platinum cocatalyst.
Exploring the evolution of a viral internal ribosome entry site
Creators: name: Wang, Xinying
Publisher: name: University of British Columbia
Year: 2022

description: The dicistrovirus intergenic region internal ribosome entry site (IGR IRES) adopts a triple-pseudoknot (PK) structure to directly bind to the conserved core of the ribosome and drive translation from a non-AUG codon. The origin of this IRES mechanism is not known. In this thesis, I describe two studies that attempt to examine how the IGR IRES may have come about. In the first study, I characterized an IGR IRES from a 700-year-old dicistrovirus, named ancient Northwest territories cripavirus (aNCV). From structural prediction of the aNCV IGR sequence and filter binding assays, we showed that the aNCV IGR secondary structure is similar to contemporary IGR IRES structures and could tightly bind to purified human ribosomes. However, there are differences including 105 nucleotides upstream of the IRES of unknown function. We also demonstrated that the aNCV IGR IRES can direct internal ribosome entry in vitro. Lastly, we generated a chimeric virus clone by swapping the aNCV IRES into the cricket paralysis virus (CrPV) infectious clone. The chimeric infectious clone with an aNCV IGR IRES supported translation and virus infection. The characterization and resurrection of a functional IGR IRES from a divergent 700-year-old virus provides a historical framework of the importance of this viral translational mechanism. In the second study, I have examined candidate RNAs that may have IGR IRES-like properties from the Drosophila genome. Previously, we adapted a selective evolution approach to identify RNA elements in the Drosophila genome which have IGR IRES-like properties. From the potential candidate RNAs, RNA3, RNA5 and RNA7 showed tight binding to purified human ribosomes. However, in a competition assay only RNA5 could compete with excess wild-type but not mutant CrPV IGR IRESs for ribosomes. However, we demonstrated that RNA5 did not bind to ribosomal core, as it was accessible by RNase I. Structural predictions were used to identify stemloop (SL) structures of RNA5. Mutations at SL2 altered RNA5 binding affinity, suggesting a potential interaction region. Finally, incubation of RNA5 in rabbit reticulocyte lysate (RRL) did not affect translation in vitro.
