description: Critical for digital innovation in the sector of agriculture, open data is diverse across different agricultural fields. Fourteen dataset categories are listed as important to be assessed for openness in Croatian open data ecosystem using the TODO readiness framework. Governmental responsibility to collect, maintain and enable timely, comprehensive, comparable and interoperable data is supported by Interdisciplinary research group focused on open data founded in 2020 at University of Zagreb Faculty of Agriculture. Connecting agriculture data to specific stakeholder needs depends upon defining the six common policies for the specific agricultural fields. Of the six policies empowering the small producers is emphasized. Preliminary landscaping results show the Open data portal (open.gov.hr) is not being used by the central or other government organizations of the agriculture sector. Data sets and data files available via the internet pages of the Ministry of agriculture, the Croatian agency for agriculture and food, as well as the Paying Agency for Agriculture, Fisheries and Rural Development are using predominately closed file formats. Databases and applications of the mentioned organizations curated for diverse target groups provide access with registration and no information on how users can be registered. NGOs are also providing data and portals in the role of citizen science that can be useful for the sector (e.g. biologer.hr). Centers of excellence provide and curate databases and provide portals of good spatial data quality (e.g. cpgrd.hapih.hr). Data literacy assessment of the sector based on the literacy provided by the courses of Faculty of agriculture shows developing digital competences of the students and developing data literacy of the lecturers is not the focus of the institution. Additionally, the technical and conceptual skills required to understand and effectively use data, and to combine domain knowledge with data literacy is present in 8% of the undergraduate and 24% of the master courses according to the ECTS catalogue. In conclusion, open data research of the agricultural sector should focus on identifying distinct data needs across different fields with emphasis on the small producers. Developing open data ecosystem in the sector of agriculture in Croatia requires raising of the data literacy in the sector and empowering the governmental institutions in upgrading current level of open data provision by national and local-level consultations and the uptake of good examples and synergy with institutions of the sector of nature and environment.

description: This paper constructs the reduction of heterotic $M$-theory in eleven dimensions to a supergravity model on a manifold with boundary in five dimensions using a Calabi-Yau three-fold. New results are presented for the boundary terms in the action and for the boundary conditions on the bulk fields. Some general features of dualisation on a manifold with boundary are used to explain the origin of some topological terms in the action. The effect of gaugino condensation on the fermion boundary conditions leads to a `twist' in the chirality of the gravitino which can provide an uplifting mechanism in the vacuum energy to cancel the cosmological constant after moduli stabilisation.

title: Book printing at the university press at Oxford between 1660 and 1780
Creators: name: Ould, M.A
Publisher: name: Bath Spa University

description: My research has yielded publications that contribute to the field of printing history through the first comprehensive accounts of the operation of two large English printing houses in the seventeenth and eighteenth centuries: the Learned Press at Oxford in the period 1660 to 1780 and the Oxford Bible Press in the period 1769 to 1772. Those publications contribute to the field in two ways. Firstly, my research into the Oxford Bible Press in the period 1769 to 1772 reveals operational features of a large printing house that could otherwise only be speculated about, in particular the extent and nature of concurrent printing there*. Secondly, my research into the Learned Press at Oxford has produced insights into the operation of a large printing house at a level not seen before, surpassing in detail D. F. McKenzie’s description of the Cambridge University Press in the period 1696 to 1712. Both areas contribute extensive economic data for the period, including pay rates, the prices of materials and services, productivity figures, and the movement of workers. Moreover, from the basis established by my publications I have been able to widen my contribution by confirming and in some cases challenging McKenzie’s assertions about the operation of an eighteenth-century printing house. (*‘Concurrent printing’ is a term used for the situation where more than one work is in hand in a Press at any one time.)

description: We present ion-by-ion cooling efficiencies for low-density gas. We use Cloudy (ver. 08.00) to estimate the cooling efficiencies for each ion of the first 30 elements (H-Zn) individually. We present results for gas temperatures between 1e4 and 1e8K, assuming low densities and optically thin conditions. When nonequilibrium ionization plays a significant role the ionization states deviate from those that obtain in collisional ionization equilibrium (CIE), and the local cooling efficiency at any given temperature depends on specific non-equilibrium ion fractions. The results presented here allow for an efficient estimate of the total cooling efficiency for any ionic composition. We also list the elemental cooling efficiencies assuming CIE conditions. These can be used to construct CIE cooling efficiencies for non-solar abundance ratios, or to estimate the cooling due to elements not explicitly included in any nonequilibrium computation. All the computational results are listed in convenient online tables.

Cash Transfers in Emergencies

Publisher: name: Columbia University
Year: 2012
Subjects: Social service

description: The famine that began in the Horn of Africa during the summer of 2011 is the worst that the region has seen in over 60 years. With 13.3 million people in need of assistance and the lives of 750,000 in jeopardy, there is an urgent need for a quick and effective response. A growing body of evidence suggests that cash transfers are the most appropriate means of providing assistance in food emergencies. This paper examines the use of cash transfers in food emergencies by providing a brief overview of food security and famines, reviewing literature on the use of cash transfers, and providing an example of cash transfer intervention implemented in Somalia between 2003 and 2004. With evidence of the effectiveness of cash transfers in specific contexts, the question remains why these interventions are not more readily used. This paper argues that the reluctance to use cash transfers is rooted in paternalism, and calls upon donors and organizations to reexamine themselves and their organizations in an effort to not only restore dignity to those in need, but to save lives.

description: A shell-model study of proton-neutron pairing in $2p1f$ shell nuclei using a parametrized hamiltonian that includes deformation and spin-orbit effects as well as isoscalar and isovector pairing is reported. By working in a shell-model framework we are able to assess the role of the various modes of proton-neutron pairing in the presence of nuclear deformation without violating symmetries. Results are presented for $^{44}$Ti, $^{45}$Ti, $^{46}$Ti, $^{46}$V and $^{48}$Cr to assess how proton-neutron pair correlations emerge under different scenarios. We also study how the presence of a one-body spin-obit interaction affects the contribution of the various pairing modes.

Feasibility study of hybrid wood steel structures
Creators: name: Khorasani, Yalda
Publisher: name: University of British Columbia
Year: 2011

description: This thesis involves a detailed study of steel-wood hybrid structures and their applications in construction industry. Hybrid structures combine benefits of dissimilar materials to overcome their individual limitations. Various advantages and challenges of steel-timber hybrid structures are presented. Benefits include increase in tensile capacity, seismic performance, fire resistance of the structure, and cost savings. Challenges with this type of hybrid structures originate from the differences in the properties of the materials used. Connection design may be more difficult as temperature and humidity variations have different effects on steel and timber. The hybrid materials can be integrated at component levels (hybrid slab/diaphragms, hybrid beams, hybrid columns, hybrid diagonals, hybrid post-tensioned joints) and/or at the building system levels (hybrid frames, hybrid system of steel frames and wood diaphragms, vertical mixed system and hybrid trusses). To elaborate on these types of hybridization and their advantages and challenges, case studies of steel-timber, concrete-timber and steel-concrete structures are provided. Despite the obvious advantages, today’s applications of wood-steel hybrid structures have been limited. Currently there are no material and design standards for hybrid wood-steel structures. For light structures, NAHB Research Center has developed a builder’s guide to hybrid wood and steel connection details. When combining steel and wood, designers should consider the advantages and limitation of each material and optimally utilize them. The literature review has highlighted the opportunity for wood-steel hybrid buildings and existing knowledge gaps. Another aim of this thesis is to investigate technical software packages and identify the pros and cons of each software pachage for modeling hybrid structures. The considered software packages are ANSYS, SAPWood, SeismoStruct and OpenSees Navigator. Software packages are evaluated interms of their ability to model linear and non linear materials; orthotropic and istotropic materials and composite materials. among the softwares ANSYS is found to be the most suitable for modelling hybird wood and steel structures. A case study of a hybird structure consisting of steel momet frame and wood shear wall is modeled with ANSYS. Static analysis is performed on the structure and it is observed that wood shear wall significantly reduce the lateral deflection of the system.

description: The insider threat remains one of the most vexing problems in computer security. A number of approaches have been proposed to detect nefarious insider actions including user modeling and profiling techniques, policy and access enforcement techniques, and misuse detection. In this work we propose trap-based defense mechanisms for the case where insiders attempt to exfiltrate and use sensitive information. Our goal is to confuse and confound the attacker requiring far more effort to identify real information from bogus information and to provide a means of detecting when an inside attacker attempts to exploit sensitive information. "Decoy Documents" are automatically generated and stored on a file system with the aim of enticing a malicious insider to open and review the contents of the documents. The decoy documents contain several different types of bogus credentials that when used, trigger an alert. We also embed "stealthy beacons" inside the documents that cause a signal to be emitted to a server indicating when and where the particular decoy was opened. We evaluate decoy documents on honeypots penetrated by attackers demonstrating the feasibility of the method.
The bright $N$-soliton solution of a multi-component modified nonlinear Schrödinger equation

description: A direct method is developed for constructing the bright $N$-soliton solution of a multi-component modified nonlinear Schrödinger equation. Specifically, the two different expressions of the solution are obtained both of which are expressed as a rational function of determinants. A simple relation is found between them by employing the properties of the Cauchy matrix. The proof of the solution reduces to the bilinear equations among the bordered determinants in which Jacobi's identity and related formulas play a central role. Last, the bright $N$-soliton solution is presented for a (2+1)-dimensional nonlocal model equation arising from the multi-component system as the number of dependent variables tends to infinity.

description: Our everyday lives unfold in an abundance of origin and destination places: home, work; lobby, office; my house, your house. Between origin and destination lies a space belonging to neither, a liminal space, a point in the journey that is not A or B. In this research, liminal space refers to threshold or transition space in the physical realm such as a doorway; in the digital realm such as the act of using a mobile phone while engaged in another activity; and in the conceptual realm such as engaging in interdisciplinary collaboration. There is a tacit social protocol for existing in these spaces and people establish habits or mannerisms to avoid uncomfortable interactions with strangers. As such, my research arises from my observations of people’s interactions with each other in liminal spaces. My doctoral research is focused on creating interactive art that can bring people together in liminal places, with the aim of informing the design of interactive technology that can help people connect and engage with each other. The processes established in this research can subsequently inform future endeavours for designing for engagement with site-specific interactive installations. I examined lived experience within liminal spaces and applied social interaction theory to the design and creation of interactive art installations that can challenge and transform liminal spaces and the experiences within them.
title: "My body shall pay recompense": the embodiment of Margaret in selected staged and televised cycles of the first tetralogy
Creators: name: Hipkiss, K
Publisher: name: Bath Spa University
Year: 2021

description: This is a critical study of the body of Queen Margaret in performance in selected cycles of the first tetralogy (the three parts of 'Henry VI' and 'Richard III'). Focussing on four major British cycles (two by the Royal Shakespeare Company and two by the British Broadcasting Corporation), the study places each cycle within its cultural and theatrical or televisual context and analyses how these selected productions present Margaret and her theatrical mirrors, and how they embody (or refuse to embody) contemporaneous concepts of female transgression. The introduction provides an overview of the aims and objectives of the work and an introduction to the methodological approaches used. The first chapter analyses the presentation of Margaret's hair in production photographs from two Royal Shakespeare Company cycles either side of the sexual revolution (1963 and 1977), and creates a theorised performance history that explores how the cycles interacted with prevalent cultural ideas of female sexuality, as well as representing a change in Royal Shakespeare Company management. The second chapter examines Jane Howell's 1983 BBC cycle­ - part of the BBC/Time-Life complete works project - and how Howell used televisual and theatrical techniques to create a cycle that both literally and figuratively centred Margaret and her theatrical mirrors. The third and final chapter analyses Dominic Cooke's 2016 BBC cycle 'The Hollow Crown: The Wars of the Roses', and how the creative direction of the cycle, its star actors, and its existence in a time of large scale cinematically realistic and bombastic television, made for a cycle that both allowed characters to marginalise and use female bodies, and did so itself. The conclusion of the study draws together these analytical threads, and outlines how each of the approaches contribute to a larger critical study of the body of Margaret in performance.

Would different decisions have been made if the decision-making process-including the participants in that process-had been different?"

description: We study the quantum dynamics of cold Bose atoms in a double well. It is shown that self-trapping, as well as population oscillations are common phenomena associated to nonlinear interactions. For larger $U/t$, multi-particle tunneling is damped and the quantum dynamics is dominated by the single-particle tunneling. The many-body system can be effectively described in a truncated Fock space. It exhibits coherence-decoherence oscillations in the temporal evolution. We predict a novel phenomenon of dynamical revival and collapse of matter wave fields in optical lattices in regimes near the superfluid-Mott insulator phase boundary.

description: Advances in weather and climate research have demonstrated the role of the stratosphere in the Earth system across a wide range of temporal and spatial scales. Stratospheric ozone loss has been identified as a key driver of Southern Hemisphere tropospheric circulation trends, affecting ocean currents and carbon uptake, sea ice, and possibly even the Antarctic ice sheets. Stratospheric variability has also been shown to affect short-term and seasonal forecasts, connecting the tropics and midlatitudes and guiding storm-track dynamics. The two-way interactions between the stratosphere and the Earth system have motivated the World Climate Research Programme's (WCRP) Stratospheric Processes and their Role in Climate's (SPARC) activity on Modelling the Dynamics and Variability of the Stratosphere-Troposphere System (DynVar) to investigate the impact of stratospheric dynamics and variability on climate. This assessment will be made possible by two new multimodel datasets. First, roughly 10 models with a well-resolved stratosphere are participating in the Coupled Model Intercomparison Project phase 5 (CMIP5), providing the first multimodel ensemble of climate simulations coupled from the stratopause to the sea floor. Second, the Stratosphere Resolving Historical Forecast Project (Strat-HFP) of WCRP's Climate Variability and Predictability (CLIVAR) program is forming a multimodel set of seasonal hind-casts with stratosphere-resolving models, revealing the impact of both stratospheric initial conditions and dynamics on intraseasonal prediction. The CMIP5 and Strat-HFP model datasets will offer an unprecedented opportunity to understand the role of the stratosphere in the natural and forced variability of the Earth system and to determine whether incorporating knowledge of the middle atmosphere improves seasonal forecasts and climate projections.

description: Wiedemann’s paper, introducing his algorithm for sparse and structured matrix computations over arbitrary fields, also presented a pair of matrix preconditioners for computations over small fields. The analysis of the second of these is extended in order to provide more explicit statements of the expected number of nonzero entries in the matrices obtained as well as bounds on the probability that such matrices have maximal rank. This is part of ongoing work to establish that this matrix preconditioner can also be used to bound the number of nontrivial nilpotent blocks in the Jordan normal form of a preconditioned matrix, in such a way that one can also sample uniformly from the null space of the originally given matrix. If successful this will result in a black box algorithm for the type of matrix computation required when using the number field sieve for integer factorization that is provably reliable and — by a small factor — asymptotically more efficient than alternative techniques that make use of other matrix preconditioners or require computations over field extensions.

description: Breast cancer incidence rates are low but rising in urban Mongolia. We collected reproductive and lifestyle factor information and measured anthropometrics and serum sex steroid concentrations among 314 premenopausal women living in Ulaanbaatar, Mongolia. Mean differences in hormone concentrations by these factors were calculated using age-adjusted quadratic regression splines. Estrone and estradiol in college-educated women were, respectively, 18.2% (p = 0.03) and 23.6% (p = 0.03) lower than in high-school-educated women. Progesterone concentrations appeared 55.8% lower (p = 0.10) in women residing in modern housing compared with women living in traditional housing (gers), although this finding was not statistically significant. Testosterone concentrations were positively associated with adiposity and central fat distribution; 17.1% difference (p = 0.001) for highest vs. lowest quarter for body mass index and 15.1% difference (p = 0.005) for waist-to-height ratio. Estrogens were higher in the follicular phase of women who breastfed each child for shorter durations. A distinct hormonal profile was associated with an urban lifestyle in premenopausal, Mongol women. In particular, heavier, more-educated women living in urban dwellings had higher testosterone and lower estrogen and progesterone levels. Higher breast cancer incidence in urban compared with rural women suggest that the hormonal profile associated with a more traditional lifestyle may be protective among Mongol women.
Comet C/2011 W3 (Lovejoy): Orbit Determination, Outbursts, Disintegration of Nucleus, Dust-Tail Morphology, and Relationship to New Cluster of Bright Sungrazers

description: We describe the physical and orbital properties of C/2011 W3. After surviving perihelion, the comet underwent major changes (permanent loss of nuclear condensation, formation of spine tail). The process of disintegration culminated with an outburst on December 17.6 (T+1.6 d) and this delayed response is inconsistent with the rubble pile model. Probable cause was thermal stress from the heat pulse into the nucleus after perihelion, which could also produce fragmentation of sungrazers far from the Sun. The spine tail was a synchronic feature, made up of dust released at <30 m/s. Since the nucleus would have been located on the synchrone, we computed the astrometric positions of the missing nucleus as the coordinates of the points of intersection of the spine tail's axis with lines of forced orbital-period variation, derived from orbital solutions based on preperihelion astrometry from the ground. The resulting osculating orbital period was 698+/-2 years, which proves that C/2011 W3 is the first major member of the predicted new, 21st-century cluster of bright Kreutz-system sungrazers. The spine tail's tip contained dust 1-2 mm in diameter. The bizarre appearance of the dust tail in images taken hours after perihelion with coronagraphs on SOHO and STEREO is readily understood. The disconnection of the comet's head from the preperihelion tail and the apparent activity attenuation near perihelion are both caused by sublimation of all dust at heliocentric distances smaller than ~1.8 solar radii. The tail's brightness is strongly affected by forward scattering of sunlight by dust. The longest-imaged grains had a radiation-pressure parameter beta ~ 0.6, probably submicron-sized silicate grains. The place of C/2011 W3 within the hierarchy of the Kreutz system and its genealogy via a 14th century parent suggest that it is indirectly related to the celebrated sungrazer X/1106 C1.

description: In meinem Beitrag möchte ich mich mit den Möglichkeiten des gemeinschaftlichen Gebrauchs von Bildern und Geschichten als Anlass eines (Ver-)Lernens von Begegnungen mit der Zukunft auseinandersetzenvor. Den Hintergrund meiner Auseinandersetzung bildet dabei die Ausgangsthese, dass eine emotionale Bindung zum Gegenstand wie auch das Bilden anderer Imaginationen für eine nachhaltige Pädagogik der Zukunft unabdingbar sind. Dabei interessiere ich mich vor allem für die Frage, wie Bilder und Geschichten über die Zukunft, also Science Fiction im weiteren Sinne, dazu beitragen können, dass wir gemeinsam die lähmende und paralysierende Vorstellung einer verlorenen Zukunft durch die Auswirkungen der ökologischen Krise konfrontieren mit affektiven Gegenbildern, die auf unsere Imaginationen wirken und uns in der Folge wieder handlungsfähig machen können. Um vom Vorstellen zum Handeln kommen zu können, werde ich für eine spielerische, (inter-)aktive Auseinandersetzung mit Bildern und Geschichten plädieren. Ich werde dabei das Beispiel des Videospiels Children of Morta (2019) heranziehen, um zunächst theoretisch entwickelte Überlegungen in Auseinandersetzung mit Judith Butler, Ruth Sonderegger und Gayatri Spivak zu konkretisieren. Schließen werde ich mit einem Ausblick, wie Spielräume und (Ver-)Lernräume im Unterricht in Beziehung gesetzt werden könnten.

description: In this study we investigate the optical photometric properties of early-type galaxies in the Virgo cluster core region, by analysing their location on the colour magnitude relation (CMR) and the structural scaling relations down to faint magnitudes, and by constructing the luminosity function to compare it with theoretical expectations. We visually select potential cluster members based on morphology and angular size, excluding spiral galaxies. A photometric analysis has been carried out for 295 galaxies, using surface brightness profile shape and colour as further criteria to identify probable background contaminants. 216 galaxies are considered to be certain or probable Virgo cluster members. Our study reveals 77 galaxies not catalogued in the VCC (with 13 of them already found in previous studies) that are very likely Virgo cluster members because they follow the Virgo CMR and exhibit low Sersic indices. Those galaxies reach -8.7 mag in V band. The CMR shows a clear change in slope from dEs to dSphs, while the scatter of the CMR in the dSph regime does not increase significantly. Our sample might, however, be somewhat biased towards redder colours. The scaling relations given by the dEs appear to be continued by the dSphs indicating a similar origin. The observed change in the CMR slope may mark the point at which gas loss prevented significant metal enrichment. The almost constant scatter around the CMR possibly indicates a short formation period, resulting in similar stellar populations. The luminosity function shows a Schechter function's faint end slope of -1.50\pm0.17, implying a lack of galaxies related to the expected number of low-mass dark matter haloes from theoretical models. Our findings could be explained by suppressed star formation in low-mass dark matter halos or by tidal disruption of dwarfs in the dense core region of the cluster.

description: We present a measurement of the Lyman alpha flux probability distribution function (PDF) measured from a set of eight high resolution quasar spectra with emission redshifts at 3.3 < z < 3.8. We carefully study the effect of metal absorption lines on the shape of the PDF. Metals have a larger impact on the PDF measurements at lower redshift, where there are fewer Lyman alpha absorption lines. This may be explained by an increase in the number of metal lines which are blended with Lyman alpha absorption lines toward higher redshift, but may also be due to the presence of fewer metals in the intergalactic medium with increasing lookback time. We also provide a new measurement of the redshift evolution of the effective optical depth, tau_eff, at 2.8 < z < 3.6, and find no evidence for a deviation from a power law evolution in the log(tau_eff)-log(1+z) plane. The flux PDF measurements are furthermore of interest for studies of the thermal state of the intergalactic medium (IGM) at z ~ 3 . By comparing the PDF to state-of-the-art cosmological hydrodynamical simulations, we place constraints on the temperature of the IGM and compare our results with previous measurements of the PDF at lower redshift. At redshift z=3, our new PDF measurements are consistent with an isothermal temperature-density relation, T=T_0 Delta^{gamma-1}, with a temperature at the mean density of T_0 = 19250 +/- 4800 K and a slope gamma=0.90+/-0.21 (1 sigma uncertainties). In comparison, joint constraints with previous PDF measurements at z<3 favour an inverted (gamma<1) temperature-density relation with T_0=17900 +/- 3500 K and gamma=0.70 +/- 0.12, in broad agreement with previous analyses.

description: We present here an experimental set-up to perform simultaneously measurements of surface plasmon resonance (SPR) and X-ray absorption spectroscopy (XAS) in a synchrotron beamline. The system allows measuring in situ and in real time the effect of X-ray irradiation on the SPR curves to explore the interaction of X-rays with matter. It is also possible to record XAS spectra while exciting SPR in order to detect the changes in the electronic configuration of thin films induced by the excitation of surface plasmons. Combined experiments recording simultaneously SPR and XAS curves while scanning different parameters can be carried out. The relative variations in the SPR and XAS spectra that can be detected with this set-up ranges from 10-3 to 10-5, depending on the particular experiment.

description: Evidence supporting the use of second generation antipsychotics (SGAs) in the treatment of acute depression with mixed features (MFs) associated with bipolar disorder (BD) is scarce and equivocal. Therefore, we conducted a systematic review and preliminary meta-analysis investigating SGAs in the treatment of acute BD depression with MFs. Two authors independently searched major electronic databases from 1990 until September 2015 for randomized (placebo-) controlled trials (RCTs) or open-label clinical trials investigating the efficacy of SGAs in the treatment of acute bipolar depression with MFs. A random-effect meta-analysis calculating the standardized mean difference (SMD) between SGA and placebo for the mean baseline to endpoint change in depression as well as manic symptoms score was computed based on 95% confidence intervals (CI). Six RCTs and one open-label placebo-controlled studies (including post-hoc reports) representing 1023 patients were included. Participants received either ziprasidone, olanzapine, lurasidone, quetiapine or asenapine for an average of 6.5 weeks across the included studies. Meta-analysis with Duval and Tweedie adjustment for publication bias demonstrated that SGA resulted in significant improvements of (hypo-)manic symptoms of bipolar mixed depression as assessed by the means of the total scores of the Young Mania Rating Scale (YMRS) (SMD −0.74, 95% CI −1.20 to −0.28, n SGA = 907, control = 652). Meta-analysis demonstrated that participants in receipt of SGA (n = 979) experienced a large improvement in the Montgomery–Åsberg Depression Rating Scale (MADRS) scores (SMD −1.08, 95% CI −1.35 to −0.81, p < 0.001) vs. placebo (n = 678). Publication and measurement biases and relative paucity of studies. Overall, SGAs appear to offer favorable improvements in MADRS and YMRS scores vs. placebo. Nevertheless, given the preliminary nature of the present report, additional original studies are required to allow more reliable and clinically definitive conclusions.
A hybrid effective stress – total stress procedure for analyzing soil embankments subjected to potential liquefaction and flow

description: Seismic design of major civil structures (bridges, dams and embankments) is moving increasingly towards using performance design methodologies which require determination of earthquake induced movements. Development of these numerical design tools and procedures for use in engineering practice for estimating the earthquake induced ground deformations of potentially liquefiable soil is the topic of this dissertation. Fully coupled effective stress numerical analyses procedures developed at the University of British Columbia (UBC) were used to simulate field and centrifuge test case histories. These analyses can offer considerable insight, but due to the complexity of the problem and variability of the parameters involved, there is considerable uncertainty. The author, therefore, recommends that the relatively new state-of-the-art effective stress analyses should be augmented by carrying out an additional analysis compatible with conventional design processes. This latter analysis uses published post-liquefaction “residual” soil strengths derived from back-analysis of field case histories by others. The developed design methodology uses the effective stress (UBCSAND) soil constitutive model for dynamic analyses, and empirical “residual” post-liquefaction soil strengths for a post-shaking total stress static analysis. In the proposed approach, the effective stress dynamic analysis is used to determine zones of liquefaction, to quantify earthquake induced deformations, and to provide overall insight. The post-shaking total stress static analysis, with “residual” strength parameters used in elements which liquefied, is carried out to capture the effects of complex stratigraphy and localization that may be missed by the effective stress model. Calibration and validation of the UBCSAND model was undertaken by comparing the model with field case histories and laboratory simple shear, shake table, and centrifuge tests. The measured response of some centrifuge tests being used for validation was indicative of the centrifuge model not being fully saturated. This was problematic as P-wave measurements within the centrifuge model suggested full saturation. A series of triaxial tests with P-wave measurements was carried out. These tests, and the numerical modeling of them, showed that high P-wave velocities were not always indicative of full saturation and they provided a logical explanation for the observed centrifuge response.

description: We use low-energy electron microscopy to investigate how graphene grows on Cu(111). Graphene islands first nucleate at substrate defects such as step bunches and impurities. A considerable fraction of these islands can be rotationally misaligned with the substrate, generating grain boundaries upon interisland impingement. New rotational boundaries are also generated as graphene grows across substrate step bunches. Thus, rougher substrates lead to higher degrees of mosaicity than do flatter substrates. Increasing the growth temperature improves crystallographic alignment. We demonstrate that graphene growth on Cu(111) is surface diffusion limited by comparing simulations of the time evolution of island shapes with experiments. Islands are dendritic with distinct lobes, but unlike the polycrystalline, four-lobed islands observed on (100)-textured Cu foils, each island can be a single crystal. Thus, epitaxial graphene on smooth, clean Cu(111) has fewer structural defects than it does on Cu(100).

description: Oleanolic acid (1), ursolic acid (2), hederagenin (3), betulinol (4), betulinic acid (5), and glycyrrhetinic acid (6) are obtained from acorn/licorice industrial wastes with common triterpenoid structure as a model set for esterification. Eight 3,4,5-methoxybenzoyl triterpenoid derivatives (1a–6a), including four new derivatives (1a, 3a–1, 3a–2, and 3a–3), are synthesized by classical procedures. Their antitumor and anti-hepatic fibrosis activities are evaluated on four human tumor cell lines and t-HSC/Cl-6 cells. Derivative 1a shows maximum antiproliferative effects against all cell lines, especially against tumor cells with IC50 values in the range of 5.32–15.23 μM, but does not affect the viability of normal cells. The anti-tumor mechanisms of 1a are also investigated by western blot and docking studies. The 3,4,5-methoxybenzoyl triterpenoids offers an intriguing solution for naturally derived antitumor drugs and may be invaluable for further development of cancer therapy.

description: Periodic epidemics of malaria are a major public health problem for many sub-Saharan African countries. Populations in epidemic prone areas have a poorly developed immunity to malaria and the disease remains life threatening to all age groups. The impact of epidemics could be minimized by prediction and improved prevention through timely vector control and deployment of appropriate drugs. Malaria Early Warning Systems are advocated as a means of improving the opportunity for preparedness and timely response. Rainfall is one of the major factors triggering epidemics in warm semi-arid and desert-fringe areas. Explosive epidemics often occur in these regions after excessive rains and, where these follow periods of drought and poor food security, can be especially severe. Consequently, rainfall monitoring forms one of the essential elements for the development of integrated Malaria Early Warning Systems for sub-Saharan Africa, as outlined by the World Health Organization. The Roll Back Malaria Technical Resource Network on Prevention and Control of Epidemics recommended that a simple indicator of changes in epidemic risk in regions of marginal transmission, consisting primarily of rainfall anomaly maps, could provide immediate benefit to early warning efforts. In response to these recommendations, the Famine Early Warning Systems Network produced maps that combine information about dekadal rainfall anomalies, and epidemic malaria risk, available via their Africa Data Dissemination Service. These maps were later made available in a format that is directly compatible with HealthMapper, the mapping and surveillance software developed by the WHO's Communicable Disease Surveillance and Response Department. A new monitoring interface has recently been developed at the International Research Institute for Climate Prediction (IRI) that enables the user to gain a more contextual perspective of the current rainfall estimates by comparing them to previous seasons and climatological averages. These resources are available at no cost to the user and are updated on a routine basis.
