description: This thesis describes a qualitative single exploratory case study whose purpose was to explore the potential transition of an introductory computer module of College X to a blended learning mode; this was implemented by investigating the perceptions of instructors and students regarding this potential transition, analysing these perceptions using thematic analysis, and framing these within the conceptual framework suggested by Passey (2019). In this respect, integrating ‘new’ ways of teaching and learning for implementing blended learning provision for higher education followed the steps suggested by Passey (2019). The process involved: (1) identifying the elements of the module under investigation that need to remain on-site; (2) associate the remaining elements to suitable ‘new’ ways of learning; (3) associate these elements to appropriate forms of interaction; (4) match these elements to relevant educator modes; and (5) identify the appropriate technology resources to support these elements. This process produced a set of tools that may serve as conceptual frameworks related to the relationships between online elements, educator modes, ‘new’ ways of learning, and interaction forms. Finally, the study’s findings include identified benefits and challenges related to blended learning provisions, as perceived by this study’s participants, aligned with evidence from the prevailing literature. The findings will be used to inform the eventual implementation of a blended learning provision for the said module.

description: By exploring a recent model [Palmeri, J., M. Manghi, and N. Destainville. 2007. Phys. Rev. Lett. 99:088103] where DNA bending elasticity, described by the wormlike chain model, is coupled to base-pair denaturation, we demonstrate that small denaturation bubbles lead to anomalies in the flexibility of DNA at the nanometric scale, when confined in two dimensions (2D), as reported in atomic force microscopy (AFM) experiments [Wiggins, P. A., et al. 2006. Nature Nanotech. 1:137-141]. Our model yields very good fits to experimental data and quantitative predictions that can be tested experimentally. Although such anomalies exist when DNA fluctuates freely in three dimensions (3D), they are too weak to be detected. Interactions between bases in the helical double-stranded DNA are modified by electrostatic adsorption on a 2D substrate, which facilitates local denaturation. This work reconciles the apparent discrepancy between observed 2D and 3D DNA elastic properties and points out that conclusions about the 3D properties of DNA (and its companion proteins and enzymes) do not directly follow from 2D experiments by AFM.

description: Obligate avian brood parasites lay their eggs in nests of others avian species, the hosts; the latter provide all parental care to the parasitic eggs, chicks and fledglings. Brood parasites depend entirely on the hosts for reproduction, which in turn suffer fitness losses as a result of parasitism. Parasitic cowbirds (Molothrus) reduce host fitness through grasp−ejection (e.g., M. ater) or puncture (e.g., M. rufoaxillaris and M. bonariensis) of the host’s egg(s). In addition, cowbirds typically lay their eggs from an elevated position, dropping them into the host nest and damaging some eggs already in the nest. Therefore, adaptations in parasites and defense in hosts are expected to differentially shape the evolution and the resulting properties of host and parasite eggs. Here I tested this hypothesis by comparing the mechanical and structural features of eggs and shells. M. ater’s eggs were not stronger and stiffer than their large or frequent hosts’ eggs. However, such traits are still advantageous against attempts of some of their smaller hosts to pierce−eject parasitic eggs when grasp−ejection is bill−gape size−wise impossible. In turn, the two egg–puncturer cowbird species’ eggs were more puncture resistant and stiffer than host eggs, and displayed eggshell crystallographic structure that differed from those of other species. These traits would thus confer also a lower probability of being punctured by other female parasites during multiple parasitism events. One property shared by cowbirds that stood out over hosts was mechanical ’toughness’ (better ability of the shell to absorb energy elastically and to resist the propagation of small cracks). This trait provides protection to the parasite egg against damage during laying from an elevated position, while causing damage to host eggs, and this trait provides protection when other cowbird eggs are laid in nests with multiple parasitism. By studying the shifts in mechanical and ultrastructural features of the incubated egg in egg−puncturer parasites and frequent hosts, where no differences in shell strength, stiffness, and toughness at hatching were detected between these two parasites and hosts. These findings indicate that parasitic embryos do not need to engage greater effort during hatching relative to host embryos. Finally, grasp−ejection and egg−puncture parasitic behaviors appear to induce evolutionary defenses in their frequent hosts by differentially affecting the egg shape and size (larger, rounded and asymmetrical eggs), and the shell strength and stiffness, to reduce the chance of cowbird mediated host−egg removal and puncture, in the respective host species.

Ultraviolet disinfection of unfiltered water supplies : exploring effects of particle-microorganism association and efficiency enhancement strategies
Creators: name: Soleimanpour Makuei, Mehrnaz
Publisher: name: University of British Columbia
Year: 2024

description: Traditional quality indicators used in water treatment facilities have limitations in assessing particle-related challenges and system performance under challenging conditions. This study seeks to explore the impacts of particle-microorganism interactions on ultraviolet (UV) disinfection performance, identify water quality indicators that best describe performance, and suggest innovative methodologies to mitigate these effects on disinfection performance. Several sampling points of two full-scale treatment plants, receiving surface water without filtration, were monitored to identify the impacts of particulates on UV performance. The research established a link between zeta potential or surface charge and disinfection effectiveness and results suggest that conventional water quality indicators do not adequately capture particle effects on UV disinfection. An examination of methods for detecting particle-microorganism associations was conducted to devise an experimental approach in line with contemporary research directions and supported by a reasonable theoretical foundation. To further explore the impact of challenging source conditions on UV disinfection, the second objective was to study a wider variety of water conditions. Results suggested that disinfection could be compromised even at low turbidities (< 1 NTU), depending on the water matrices. Furthermore, complex interactions with background source water quality and additional particulate and dissolved matters were observed and suggested that non-specific indicators (turbidity or UVT) as opposed to specific indicators (zeta potential) should be used with caution when predicting the UV performance specifically under challenging conditions. Overall, zeta potential enhanced UV disinfection predictability. The observed influence of zeta potential on UV performance led to proposing a UV enhancement strategy in relation to problems regarding particles. A new line of study was started to identify if manipulating particle-microorganism associations through zeta potential modifications was viable as disinfection enhancement strategy. Assessing zeta potential manipulation effects on water quality using bacterial and viral surrogates showed that samples with highly negative zeta potential result in reduced particle-microorganism associations and increasing disinfection efficacy. This research highlights the limitations of conventional indicators in assessing UV disinfection in challenging conditions. Zeta potential emerged as a key factor in improving assessment, leading to exploration of a novel pre-treatment approach for facilities that may experience significant impacts due to particulates.

description: We extend a theorem of Ottaviani on cohomological splitting criterion for vector bundles over the Grassmannian to the case of the symplectic isotropic Grassmanian. We find necessary and sufficient conditions for the case of the Grassmanian of symplectic isotropic lines. For the general case the generalization of Ottaviani's conditions are sufficient for vector bundles over the symplectic isotropic Grassmannian. By a calculation in the program LiE, we find that Ottaviani's conditions are necessary for Lagrangian Grassmannian of isotropic $k$-planes for $k\leq 6$, but they fail to be necessary for the case of the Lagrangian Grassmannian of isotropic 7-planes. Finally, we find a related set of necessary and sufficient splitting criteria for the Lagrangian Grassmannian.

We refer in particular to the planned books and special editions.The key idea from COSTA22 was a modernisation of methodology in support of the wider use of foresight methods amongst a diversity of contexts.The aphorism <> underlies an overt recognition of the socially constructed nature of <> and the reflexivity that operates in constructing meaning from this knowledge. The guidance note takes this discussion further.

An analysis of the phase space of Horava-Lifshitz cosmologies

description: Using the dynamical system approach, properties of cosmological models based on the Horava-Lifshitz gravity are systematically studied. In particular, the cosmological phase space of the Horava-Lifshitz model is characterized. The analysis allows to compare some key physical consequences of the imposition (or not) of detailed balance. A result of the investigation is that in the detailed balance case one of the attractors in the theory corresponds to an oscillatory behavior. Such oscillations can be associated to a bouncing universe, as previously described by Brandenberger, and will prevent a possible evolution towards a de Sitter universe. Other results obtained show that the cosmological models generated by Horava-Lifshitz gravity without the detailed balance assumption have indeed the potential to describe the transition between the Friedmann and the dark energy eras. The whole analysis leads to the plausible conclusion that a cosmology compatible with the present observations of the universe can be achieved only if the detailed balance condition is broken.

description: Following a very interesting discussion during and after the Final MC in Brussels this week, We offer you some thoughts of guidance on how you might take account of the Action in your publications that are COSTA22-inspired. We refer in particular to the planned books and special editions.The key idea from COSTA22 was a modernisation of methodology in support of the wider use of foresight methods amongst a diversity of contexts.The aphorism <> underlies an overt recognition of the socially constructed nature of <> and the reflexivity that operates in constructing meaning from this knowledge. The guidance note takes this discussion further.

Unabsorbed Seyfert 2 galaxies: the case of "naked" AGN

description: Hawkins (2004) reported on a class of "naked" AGN characterized by strong amplitude optical brightness variability and the complete absence of broad emission lines in the optical spectrum. The variability suggests that the nucleus is seen directly, however the absence of broad lines contradicts the simple formulation of Unified Models for AGN. We present the results of quasi-simultaneous spectroscopic observations with XMM-Newton and NTT (La Silla) of two "naked" AGN. We confirm the "naked" nature of Q2131-427 for which no broad emission line components have been detected in the optical spectrum and its X-ray spectrum shows no signs of intrinsic absorption. The optical and X-ray mismatch in this source cannot be ascribed to a high nuclear dust-to-gas ratio and a Compton Thick nature is ruled out on the basis of the high F(X)/F([OIII]) ratio. The Broad Line Region (BLR) may be completely absent in this source, possibly as a consequence of its low Eddington ratio. On the other hand, the optical spectrum of Q2130-431 shows H(alpha) and H(beta) broad emission line components, revealing the presence of a BLR. A mild X-ray absorption is expected in intermediate type 1.8 Seyfert galaxies like Q2130-431, however we put a very low upper limit on the column density (< 2 x 10^(20) cm^(-2)), also the low Balmer decrement suggests that the BLR itself does not suffer from reddening. We propose that in this object the BLR is intrinsically weak, making a case of "true" intermediate Seyfert galaxy. We also report on the X-ray detection of the Abell 3783 galaxy cluster in the XMM-Newton field-of-view of the Q2131-427 observation.

Convection in M-type dwarfs: predictions from 3D hydrodynamical model atmospheres
Creators: name: Klevas, J.
name: Kučinskas, A.
name: Ludwig, H.-G.
Publisher: name: Zenodo
Year: 2021

description: We present the first results from 3D hydrodynamical M-dwarf atmosphere simulations with the CO5BOLD model atmosphere code covering a range in Teff, log g and [M/H] typical to M0-M5 spectral type dwarfs. We provide a brief overview of the physical properties of the model atmospheres, with a focus on the validity of mixing length approximation for treating convection in the atmospheres of M-type dwarfs. We show that the mean entropy stratification can be matched only partially by changing the mixing length parameter in the 1D model atmospheres. Generally, good agreement between the 3D and 1D temperature profiles is found to approximately log tau Ross = -2 where convection stops in the 1D models. Importantly, there is no convective overshoot in the 1D models by definition whereas in case of 3D models extra convective overshoot leads to lower temperatures in the outer atmospheric layers. We discuss this and other implications that point to the necessity of using 3D hydrodynamical model atmospheres in the studies of M-type dwarfs.

description: We present near-IR VLT/ISAAC and mid-IR Spitzer/IRS spectroscopy of the young massive cluster in the W31 star-forming region. H-band spectroscopy provides refined classifications for four cluster members O stars with respect to Blum et al. In addition, photospheric features are detected in the massive Young Stellar Object (mYSO) #26. Spectroscopy permits estimates of stellar temperatures and masses, from which a cluster age of ~0.6 Myr and distance of 3.3 kpc are obtained, in excellent agreement with Blum et al. IRS spectroscopy reveals mid-infrared fine structure line fluxes of [Ne II-III] and [S III-IV] for four O stars and five mYSOs. In common with previous studies, stellar temperatures of individual stars are severely underestimated from the observed ratios of fine-structure lines, despite the use of contemporary stellar atmosphere and photoionization models. We construct empirical temperature calibrations based upon the W31 cluster stars of known spectral type, supplemented by two inner Milky Way ultracompact (UC) HII regions whose ionizing star properties are established. Calibrations involving [NeIII] 15.5um/[NeII] 12.8um, [SIV] 10.5um/[NeII] 12.8um or [ArIII] 9.0um/[NeII] 12.8um have application in deducing the spectral types of early- to mid- O stars for other inner Milky Way compact and UCHII regions. Finally, evolutionary phases and timescales for the massive stellar content in W31 are discussed, due to the presence of numerous young massive stars at different formation phases in a `coeval' cluster.

description: A family of nonparametric Yang Baxter (YB) maps is constructed by refactorization of the product of two 2 by 2 matrix polynomials of first degree. These maps are Poisson with respect to the Sklyanin bracket. For each Casimir function a parametric Poisson YB map is generated by reduction on the corresponding level set. By considering a complete set of Casimir functions symplectic multiparametric YB maps are derived. These maps are quadrirational with explicit formulae in terms of matrix operations. Their Lax matrices are, by construction, 2 by 2 first degree polynomial in the spectral parameter and are classified by Jordan normal form of the leading term. Nonquadrirational parametric YB maps constructed as limits of the quadrirational ones are connected to known integrable systems on quad graphs.

description: Der antiken Tradition folgend genießt Erfahrung (lat. experientia) in der Frühen Neuzeit hohes Ansehen. Ob als praktische Lebenserfahrung, naturphilosophisch-empirisches Wissen oder spirituelle Erfahrung – Erfahrungswissen gilt häufig als unersetzliches Komplement anderer, vor allem theoretisch-spekulativer Wissensformen. Insbesondere der Aufstieg des neuen naturphilosophischen Wissens, das sich im 17. Jahrhundert unter dem Signum des ‚Experiments‘ vom traditionellen Erfahrungsbegriff zu autonomisieren beginnt, hat in der jüngeren Wissensgeschichte viel Aufmerksamkeit erfahren. Mitunter hat dies die Tatsache verdeckt, dass die Konzepte von experientia als ‚Lebenserfahrung‘ und ‚spiritueller Erfahrung‘ relevant blieben. Der vorliegende Band versucht daher, das Spektrum frühneuzeitlicher Erfahrungsdiskurse noch einmal etwas breiter in den Blick zu nehmen. Anhand ausgewählter Beispiele wirft er Schlaglichter auf Kontinuitäten und Veränderungen, Schnittstellen und Berührungspunkte verschiedener Erfahrungskonzepte, wie sie in der Romania vor 1800 zu finden sind. Zutage tritt so die Vielschichtigkeit und Komplexität von Erfahrung als einem Wissenskonzept, das im täglichen Sprachgebrauch fest verankert, doch zugleich schillernd und schwer definierbar ist: letzteres auch, weil es in Teilen auf ein elusives, nicht vollständig diskursivierbares Wissen verweist.

description: The adsorption of Ar on substrates of Li is investigated within the framework of a density functional theory which includes an effective pair potential recently proposed. This approach yields good results for the surface tension of the liquid-vapor interface over the entire range of temperatures, T, from the triple point, T_t, to the critical point, T_c. The behavior of the adsorbate in the cases of a single planar wall and a slit geometry is analyzed as a function of temperature. Asymmetric density profiles are found for fluid confined in a slit built up of two identical planar walls leading to the spontaneous symmetry breaking (SSB) effect. We found that the asymmetric solutions occur even above the wetting temperature T_w in a range of average densities rho*_ssb1 <= rho*_av <= rho*_ssb2, which diminishes with increasing temperatures until its disappearance at the critical prewetting point T_cpw. In this way a correlation between the disappearance of the SSB effect and the end of prewetting lines observed in the adsorption on a one-wall planar substrate is established. In addition, it is shown that a value for T_cpw can be precisely determined by analyzing the asymmetry coefficients.

description: Melting snow and glacier surfaces host microalgal blooms in polar and mountainous regions. The aim of this study was to determine the dominant taxa at the species level in the European Arctic and the Alps. A standardized protocol for amplicon metabarcoding using the 18S rRNA gene and ITS2 markers was developed. This is important because previous biodiversity studies have been hampered by the dominance of closely related algal taxa in snow and ice. Due to the limited resolution of partial 18S rRNA Illumina sequences, the hypervariable ITS2 region was used to further discriminate between the genotypes. Our results show that red snow was caused by the cosmopolitan Sanguina nivaloides (Chlamydomonadales, Chlorophyta) and two as of yet undescribed Sanguina species. Arctic orange snow was dominated by S. aurantia, which was not found in the Alps. On glaciers, at least three Ancylonema species (Zygnematales, Streptophyta) dominated. Golden-brown blooms consisted of Hydrurus spp. (Hydrurales, Stramenophiles) and these were mainly an Arctic phenomenon. For chrysophytes, only the 18S rRNA gene but not ITS2 sequences were amplified, showcasing how delicate the selection of eukaryotic ‘universal’ primers for community studies is and that primer specificity will affect diversity results dramatically. We propose our approach as a ‘best practice’.
