The 12C(p,y)13N reaction
Creators: name: Berghofer, David
Publisher: name: University of British Columbia
Year: 2010

description: The ninety degree yield curve for the ¹²C(p,Ƴ) ¹³N reaction was examined for proton energies (Ep ) between 14 MeV and 24.4 MeV using a 99.9 % pure carbon-12 target and protons from the University of Washington FN tandem Van de Graaff. The giant dipole resonance (GDR) for the gamma transition to the ground state (Ƴ₀) was found to be centered at Ep = 20.5 MeV with a width Γ = 4 MeV and a maximum cross-section = 3 µb/sr. Intermediate structure of width Γ = 1 MeV was observed at Ep = 17.5 MeV and 23 MeV. The yield curve was compared to the ¹¹B(p,Y₀) ¹²C yield curve, and the similarities found indicated that valence nucleon transitions to the ground state play little part in the GDR of 13N. Yield curves for the transition to the first excited state (Ƴ¹) and the sum of the transitions to the second and third excited states (Ƴ2+3) are also given in the regions where they can be reliably extracted. No fine structure was observed. Measured yields of the 12.71 MeV and 15.11 MeV gamma-rays from the inelastic reaction agree well with other recent results. Proton decay widths to these states from compound nuclear states in 13N are given. Angular distributions for the (p, Ƴ₀) reaction were measured at six energies in the region of the "pygmy resonance" Ep= 10 MeV to 14 MeV, to inspect previously reported fine structure. Two narrow minima seen in the ninety degree yield are found to be minima in the integrated cross-sections, whereas the shape of the angular distribution is relatively constant.

description: The paper aims to illustrate the world of childhood in buzzatian fiction from the literature (specially La famosa invasione degli orsi in Sicilia, 1945) and from the conception of fantasy literature, until the collaboration with the "Corriere dei Piccoli" magazine (1968-1969). In terms of narrative languages, special attention deserves the narrative through words and images. In this sense, Buzzati still represents a significant 'standard of comparison' in the context of studies of children's literature.

description: The development of safety applications for Connected Automated Vehicles requires testing in many different scenarios. However, the recreation of test scenarios for evaluating safety applications is a very challenging task. This is mainly due to the randomness in communication, difficulty in recreating vehicle movements precisely, and safety concerns for certain scenarios. We propose to develop a standalone Remote Vehicle Emulator that can reproduce V2V messages of remote vehicles from simulations or previous tests. This is expected to accelerate the development cycle significantly. Remote Vehicle Emulator is a unique and easily configurable emulation cum simulation setup to allow Software in the Loop (SIL) testing of connected vehicle applications realistically and safely. It will help in tailoring numerous test scenarios, expediting algorithm development and validation, and increasing the probability of finding failure modes. This, in turn, will help improve the quality of safety applications while saving testing time and reducing cost.

description: The current study aimed to identify the impact of equipping ambulances with rapid communication mechanisms on the response time for injured individuals in emergency situations. This was achieved by employing a descriptive analytical approach through the distribution of a questionnaire consisting of 500 emergency medical technicians to assess their opinions regarding the equipping of ambulances and rapid communication mechanisms. The study's results indicated that there was no statistical significance attributed to professional and occupational experiences or the number of years of service concerning the responses of the sample on the questionnaire. The study presented several findings, including that technological advancements have facilitated the provision of higher quality communication means in ambulances, ensuring various solutions for rapid access to victims in emergencies. Furthermore, the implementation of precise location identification technology has enhanced response speed and helped avoid traffic congestion. The study's results also indicated that the quicker the access to the accident scene, the greater the chances of survival for the injured, and that there is an effect of delayed response on rescue opportunities.

description: The recently proposed "dynamically driven double-degenerate double-detonation" (D6) scenario posits that Type Ia supernovae (SNe) may occur during dynamically unstable mass transfer between two white dwarfs (WDs) in a binary. This scenario predicts that the donor WD may then survive the explosion and be released as a hypervelocity runaway, opening up the exciting possibility of identifying remnant stars from D6 SNe and using them to study the physics of detonations that produce Type Ia SNe. Three candidate D6 runaway objects have been identified in Gaia data. The observable runaway velocity of these remnant objects represents their orbital speed at the time of SN detonation. The orbital dynamics and Roche lobe geometry required in the D6 scenario place specific constraints on the radius and mass of the donor WD that becomes the hypervelocity runaway. In this letter, we calculate the radii required for D6 donor WDs as a function of the runaway velocity. Using mass-radius relations for WDs, we then constrain the masses of the donor stars as well. With measured velocities for each of the three D6 candidate objects based on Gaia EDR3, this work provides a new probe of the masses and mass ratios in WD binary systems that produce SN detonations and hypervelocity runaways.

Re-assessment of hierarchical cosmologies
Creators: name: Krebes, Edward Stephen
Publisher: name: University of British Columbia
Year: 2010

description: The extension of the concepts of Newtonian cosmology to a universe consisting of a hierarchy of metagalaxies is fairly straightforward. However, in general relativistic cosmology, the construction of such a hierarchical universe is a difficult problem. It is the purpose of this work to examine some aspects of hierarchical cosmology in both the Newtonian and general relativistic cases. It is suggested that the metagalaxy may be a black hole or Schwarzschild object,(to account for the fact that no objects which could be identified as metagalaxies have been, as yet, observed. Some features of this concept are discussed. Tidal forces exerted on a metagalaxy, due to others distributed around it, are estimated in the Newtonian case. Such tidal forces may or may not be detectable, depending on the distance between metagalaxies. The interior of a metagalaxy is represented by a Fried-mann model, with given values of k and A. The Friedmann model is matched at the boundary to a Schwarzschild spacetime. The consequences of this and related calculations suggest that in most cases, a metagalaxy may be a black hole for only part of its lifetime, i.e., for other times, it may be optically detectable to an exterior observer.
SILICA H2SO4 AS AN EFFICIENT HETEROGENEOUS CATALYST FOR THE SYNTHESIS OF NEW COUMARIN DERIVATIVES AND EVALUATION OF ANTIBACTERIAL ACTIVITY

description: The literature survey indicates that benzopyran derivatives possess different pharmacological and biological activities. Coumarin derivatives have been shown to have interesting pharmacological activities such as antibacterial, anti-inflammatory, and antifungal activities. When one biologically active molecule is linked to another, the resultant molecule generally has an increased potency. Therefore, in the present study, two systems of Coumarin and chalcone are fused to obtain highly potent, specifically anti-inflammatory and less toxic antibacterial agents. The objective of the present work is to synthesize chalcone-substituted Coumarin derivatives and in particular study their antibacterial properties. The paper makes a modest attempt in that direction.  Coumarin derivatives were synthesized using SSA as a potent catalyst. All the synthesized derivatives were characterized by 1H1 NMR, Mass spectra, and I.R. spectra. The antibacterial activity of the compounds was carried out using the disc diffusion method on nutrient agar media. Ampicillin and Gentamycin were used as standard drugs for the comparison in the concentration of 50 µg/ml and 100 µg/ml against Gram-positive and Gram-negative bacteria used for the study. Compounds 3g,3i, and 3j were found to possess good activity while compounds 3a, 3b, 3c, 3d, 3e, and 3f, were found to exhibit moderate activity. Among these various compounds 3g, 3i, and 3j particularly exhibited good activities against gram-negative bacteria. Hence, these compounds appear to be promising anti-bacterial agents. Perhaps the presence of N(CH3)2 and OH as a substituent on the aromatic nucleus attached to the 4th position attached to Coumarin nucleus at the 3rd may be responsible for the good anti-bacterial activity.

A New Paradigm for Gamma Ray Bursts: Long Term Accretion Rate Modulation by an External Accretion Disk

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present a new way of looking at the very long term evolution of GRBs in which the disk of material surrounding the putative black hole powering the GRB jet modulates the mass flow, and hence the efficacy of the process that extracts rotational energy from the black hole and inner accretion disk. The pre-Swift paradigm of achromatic, shallow-to-steep "breaks" in the long term GRB light curves has not been borne out by detailed Swift data amassed in the past several years. We argue that, given the initial existence of a fall-back disk near the progenitor, an unavoidable consequence will be the formation of an "external disk" whose outer edge continually moves to larger radii due to angular momentum transport and lack of a confining torque. The mass reservoir at large radii moves outward with time and gives a natural power law decay to the GRB light curves. In this model, the different canonical power law decay segments in the GRB identified by Zhang et al. and Nousek et al. represent different physical states of the accretion disk. We identify a physical disk state with each power law segment.

description: Among the various laboratory studies to investigate the Thermo-Hydro-Mechanical (THM) behaviour of Boom clay, relatively few were devoted to the time dependent behaviour, limiting any relevant analysis of the long-term behaviour of the disposal facility. The present work aims at investigating the time-dependent behaviour of Boom clay under both thermal and mechanical loading. High-pressure triaxial tests at controlled temperatures were carried out for this purpose. The tests started with constant-rate thermal and/or mechanical consolidation and ended with isobar heating and/or isothermal compression at a constant stress rate or by step loading. Significant effects of temperature as well as of compression and heating rates were observed on the volume change behaviour. After being loaded to a stress lower than the pre-consolidation pressure (5 MPa) at a low temperature of 25\degree C and at a rate lower than 0.2 kPa/min, the sample volume changes seemed to be quite small, suggesting a full dissipation of pore water pressure. By contrast, after being subjected to high loading and heating rates (including step loading or step heating), the volume changes appeared to be significant, particularly in the case of stresses much higher than the pre-consolidation pressure. Due to low permeability, full consolidation of Boom clay required a long period of time and it was difficult to distinguish consolidation and creep from the total volume change with time.

description: We report on the theoretical investigation of photonic crystal cavities etched on a suspended membrane for the generation of polarization entangled photon pairs using the biexciton cascade in a single quantum dot. The implementation of spontaneous emission enhancement effect increases the entanglement visibility, while the concomitant preferential funneling of the emission in the cavity mode increases the collection of both entangled photons. We demonstrate and quantify that standard cavity designs present a polarization dependent emission diagram, detrimental to entanglement. The optimization of H1 cavities allows to obtain both high collection efficiencies and polarization independent emission, while keeping high Purcell factors necessary for high quality entangled photon sources.

description: We study the UV properties of Type I AGN from the ROSAT All-Sky Survey that have been selected to show unusually soft X-ray continua. We examine a sample of 54 Seyfert 1 galaxies with detections in both Near-UV and Far-UV bands of the Galaxy Evolution Explorer (GALEX) satellite. Our sample is systematically fainter in the UV than galaxies studied in similar work by previous authors. We look for correlations between their UV and X-ray properties as well as correlations of these properties with either black hole mass or Eddington ratio. The shape of the Big Blue Bump(BBB) in the GALEX regime does not appear to correlate with its strength relative to the power law continuum, which conflicts with results reported by previous authors. The strength of the BBB is correlated with the shape of the X-ray continuum, in agreement with previous work, but the slope of the correlation is different than previously reported. The properties of the accretion disks of Type I AGN in the GALEX regime are relatively independent of black hole mass and Eddington ratio. We compare our measurements to the predictions of alternative theories for the origin of the soft excess, but we are unable to distinguish between Comptonization of BBB photons by a hot plasma and absorption in relativistic winds as the most likely origins for the soft X-ray excess.

description: This study utilized the Eulerian-Lagrangian method to investigate the risk of transmission of disease by tracking particles generated through coughing. The effects of ventilation rates (0.5, 5.0, and 10 ACH) and social distancing (0.9 and 1.8 m) were examined in a small office room using a displacement ventilation system. Numerical simulations considered different particle sizes (1, 5, 10, 20, 40, and 80 μm) to understand particle behavior and transmission routes. The airflow resulting from human coughing was validated with experimental data. Results showed that at a social distance of 0.9 m, increasing the ventilation rate led to a higher fraction of particles directly inhaled by susceptible individuals, potentially causing droplet and airborne transmission. However, maintaining a social distance of 1.8 m and a ventilation rate of 10 ACH significantly reduced the fraction of inhaled particles. Larger particles tended to deposit on floors and surfaces, while smaller particles remained suspended in the air. Higher ventilation rates increased particle deposition on the body surface of susceptible individuals, whereas increasing social distance reduced particle deposition. These findings highlight the importance of appropriate ventilation rates and social distancing in reducing the risk of infection transmission. Maintaining a social distance of 1.8 m combined with increased ventilation effectively reduced the fraction of inhaled particles. Larger particles were more likely to deposit on surfaces, emphasizing the need for regular disinfection. Understanding the dynamics of infectious particles and implementing effective ventilation and distancing measures can help mitigate the spread of infectious diseases in indoor environments.

description: Random nonlinear layered structures have been found to be a useful source of photon pairs with perfectly indistinguishable un-entangled photons emitted into a very narrow spectral range. Localization of the interacting optical fields typical for random structures gives relatively high photon-pair fluxes. Superposing photon-pair emission quantum paths at different emission angles, several kinds of two-photon states (including states with coincident frequencies) useful in quantum-information processing can easily be generated.

Studies of the Z-pinch discharge in high pressure helium

description: Improvements to the laser excited interferometer previously constructed in this laboratory are described. The use of a rotating retro-reflector in the interferometer cavity, and electronic circuitry, permit direct recording of electron densities. The sensitivity of the interferometer is 5 x 1015 cm-2, and the temporal resolution is 0.1 usee. Pyrex tubes, terminated by windows, enclosing the laser beam, have been used to improve spatial resolution. The effects of the tubes, and of all other sources of error associated with interferometric measurements of electron densities, have been carefully assessed. A Z-pinch discharge in 4 torr helium has been studied with this instrument, and with spectroscopic determinations of electron temperature. Under the conditions chosen, the pinching plasma does not reach the axis of the discharge tube, but stops at a radius of 2.7 cm. The shock front caused by the pinching action has been shown to be weak. Longitudinal structure, due to heat flux, characteristic cathode behaviour, and variations in timing of the pinching action, has been found. The discharge has been assessed as a spectroscopic source and as a medium for laser scattering experiments. The characteristics of two suitable regions are presented. These are the axial region and the hollow cylinder of plasma formed by the arrest of the pinching plasma. Both are free of instabilities. At the appropriate time the latter is also current free, and shows longitudinal electron density variations of less than 2%. The length of time that the current spends near the wall of the vessel is determined by the balance between kinetic and magnetic pressures.

description: We prove that the free Fock space ${\F}(\R^+;\C)$, which is very commonly used in Free Probability Theory, is the continuous free product of copies of the space $\C^2$. We describe an explicit embedding and approximation of this continuous free product structure by means of a discrete-time approximation: the free toy Fock space, a countable free product of copies of $\C^2$. We show that the basic creation, annihilation and gauge operators of the free Fock space are also limits of elementary operators on the free toy Fock space. When applying these constructions and results to the probabilistic interpretations of these spaces, we recover some discrete approximations of the semi-circular Brownian motion and of the free Poisson process. All these results are also extended to the higher multiplicity case, that is, ${\F}(\R^+;\C^N)$ is the continuous free product of copies of the space $\C^{N+1}$.

description: In this study, the genes involved in the initial attack on fluorene by Sphingomonas sp. LB126 were investigated. The ? and ? subunits of a dioxygenase complex (FlnA1A2), showing 63% and 51% sequence identity respectively, with the subunits of an angular dioxygenase from Gram-positive Terrabacter sp. DBF63, were identified. When overexpressed in E. coli, FlnA1A2 was responsible for the angular oxidation of fluorene, fluorenol, fluorenone, dibenzofuran and dibenzo-p-dioxin. Moreover, FlnA1A2 was able to oxidize polycyclic aromatic hydrocarbons and heteroaromatics, some of which were not oxidized by the dioxygenase from Terrabacter sp. DBF63. Quantification of resulting oxidation products showed that fluorene and phenanthrene were preferred substrates.

description: Transmission of an airborne disease can occur when an individual exhales respiratory particles that contain infectious pathogens. Surgical face masks are often used to reduce the amount of respiratory aerosol emitted into the environment by an individual while also lowering the concentration of particles the individual inhales. Respiratory aerosol generation is activity-dependent with high person-to-person variability. Moreover, mask fit differs among people. Here, we measure the efficacy of surgical masks (EN14683 Type IIR) in reducing both aerosol (0.3 − 20 µm diameter) and droplet (20 − 1000 µm diameter) emission during breathing, speaking and five speech and language therapy tasks performed by a human cohort. When participants wore a surgical face mask, measured particle number concentrations at the front of the mask were always lower than that for breathing without mitigation in place. For breathing and speaking, the through-mask filtration efficiencies were 80% and 87%, respectively, while for voice therapy tasks the through-mask filtration efficiencies ranged from 89% (“Hey!”) to 95% (/a::/). Size-dependent through-mask filtration efficiencies were high (80 – 95%) for particles 0.5 − 2 µm diameter, with masks filtering a greater fraction of larger particle sizes. For particle sizes >4 µm diameter, filtration efficiencies of surgical face masks for all tested respiratory tasks were ∼100%. Surgical face masks significantly reduced the number of particles emitted from all respiratory activities. These results have implications for developing effective mitigations for disease transmission through inhalation.

description: Thin epitaxial films of metals on insulating substrates are essential for many applications, as conducting layers, in magnetic devices or as templates for further growth. In this work, we report on the growth of epitaxial Ru films on single-crystalline Al$_2$O$_3$(0001) substrates by magnetron sputtering and their subsequent systematic characterization using Rutherford backscattering spectrometry of He ions both in random and in channeling conditions. We include results of a Ru(0001) single crystal for comparison. Analysis of channeling shows that films thicker than 35 nm grow with (0001) orientation, a well-defined epitaxial relation with the substrate and a high degree of crystal quality, comparable to the Ru(0001) single crystal. Thinner films of down to 7 nm in thickness, for which relaxation of epitaxial strain is not complete, produce a similar degree of dechanneling. The surface of the films can be prepared in a clean and ordered state in order to allow further epitaxial growth on top.

description: In the present study we focused on the region of Jericho, one of the most ancient biblical cities, presenting the well known information about it, until today, derived from three sources: a) the texts of the Old and the New Testament, b) the History and the Archeology, and c) the preserved monuments of Jericho, which are used as religious destinations and as destinations for peregrination. For the survey I used the international and the national bibliography. Jericho may be a significant destination for religious and pilgrimage tourism. The suitable material for the region's pilgrimage was presented and the possibility of the proposal for the best and the most correct exploitation of Jericho in the frame of a pilgrimage visit was examined.

description: The aim of the thesis is the preparation of protective coatings for building materials (natural stone and wood) that will repel water and oil. The effectiveness of the coatings on marble, wood and glass substrates was studied. The latter was used as a reference substrate material. During the laboratory studies, the contact angle of the water and diiodomethane drops on the coated substrates was measured. In addition, the colour changes of the samples before and after deposition of the protective film were compared. The morphology of the coatings was observed macroscopically and microscopically. The aim is to use materials compatible with natural stone and wood. The contents of the work will be divided into theoretical and experimental parts. In the theoretical part, material wear factors will be mentioned, superhydrophobic surfaces and the role of the contact angle will be analysed based on the literature. In the experimental part, all the laboratory steps for the study and preparation of the protective films will be described in detail.
