Homeless youth perspectives

description: Youth experiencing homelessness face a variety of significant challenges and rely on services to address many of their needs. When seeking to address these needs, there are two key sets of voices to consider: the voices of service providers, and the voices of the youth themselves. The present study aims to explore the needs of youth experiencing homelessness from these two perspectives, as well as to investigate whether any significant differences exist between the priorities of the two groups. Focus groups with youth experiencing homelessness and interviews with service providers were conducted in order to explore the challenges and needs of youth experiencing homelessness, and the qualitative data obtained was subjected to thematic analysis. The results showed several similarities, as well as several differences between the understandings of the two parties of the needs of youth experiencing homelessness. Overall, youth participants primarily discussed topics related to improving their quality of life while homeless, while service provider participants additionally focused on topics related to youth getting out of homelessness. Both groups of participants identified significant challenges with the accessibility of existing services, and emphasized the need for more services for youth specifically. The results suggest that some gaps do exist between what youth and service providers identify as the needs of youth experiencing homelessness, but that service providers value the voices of the people they serve. Another significant interpretation of the results is that neither service providers nor youth experiencing homelessness are fully satisfied with the support that is currently available, and that changes should be made.
Epithermal muons from solid rare-gas moderators
Creators: name: Morris, Gerald D
Publisher: name: University of British Columbia
Year: 2010

description: Emission of positive muons (μ⁺) of low kinetic energy, with yield peaked at 5 to 20 electron volts and slowly decreasing to higher energy, has been observed by moderating a muon beam (p~28MeV/c, Δp/p~4%) with solid argon, krypton and xenon moderators. Emission at these energies is consistent with the muons escaping the target material still carrying part of their initial kinetic energy. The underlying cause of this enhancement of low energy positive muons is not determined. Variation of charge-exchange, elastic or inelastic collision cross sections with energy, resulting in an increased charged fraction or greater mean free path for muons at these energies, are possible causes.

description: The network formed by ridges in a straightened sheet of crumpled paper is studied using a laser profilometer. Square sheets of paper were crumpled into balls, unfolded and their height profile measured. From these profiles the imposed ridges were extracted as networks. Nodes were defined as intersections between ridges, and links as the various ridges connecting the nodes. Many network and spatial properties have been investigated. The tail of the ridge length distribution was found to follow a power-law whereas the shorter ridges followed a log-normal distribution. The degree distribution was found to have an exponentially decaying tail, and the degree correlation was found to be disassortative. The facets created by the ridges and the Voronoi diagram formed by the nodes have also been investigated.

The X-Ray Transient 080109 in NGC 2770: an X-Ray Flash Associated with a Normal Core-Collapse Supernova
Creators: name: Li, Li-Xin
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although it is generally thought that long-duration gamma-ray bursts (LGRBs) are associated with core-collapse supernovae (SNe), so far only four pairs of GRBs and SNe with firmly established connection have been found. All the four GRB-SNe are among a special class of Type Ic--called the broad-lined SNe indicative of a large explosion energy, suggesting that only a small fraction of SNe Ibc have GRBs associated with them. This scheme has been refreshed by the discovery of a bright X-ray transient in NGC 2770 on 9 January 2008, which was followed by a rather normal Type Ib SN 2008D. In this paper, I argue that the transient 080109 is an X-ray flash (XRF, the soft version of a GRB) because of the following evidences: (1) The transient cannot be interpreted as a SN shock breakout event; (2) The GRB X-ray flare interpretation is not supported by the high-energy observation. Then I show that XRF 080109 satisfies the well-known relation between the isotropic-equivalent energy and the peak spectral energy for LGRBs, which highly strengthens the XRF interpretation. Finally, I point out that, the peak spectral energy of XRF 080109 and the maximum bolometric luminosity of SN 2008D agree with the $E_{γ,\p}$--$L_{{\rm SN},\max}$ relationship of Li (2006), strengthening the validity of the relationship. I speculate that events like XRF 080109 may occur at a rate comparable to SNe Ibc, and a soft X-ray telescope devoted to surveying for nearby X-ray flares will be very fruitful in discovering them.

description: We establish a trace formula for rigid varieties $X$ over a complete discretely valued field, which relates the set of unramified points on $X$ to the Galois action on its étale cohomology. We develop a theory of motivic integration for formal schemes of pseudo-finite type over a complete discrete valuation ring $R$, and we introduce the Weil generating series of a regular formal $R$-scheme $\mathfrak{X}$ of pseudo-finite type, via the construction of a Gelfand-Leray form on its generic fiber. Our trace formula yields a cohomological interpretation of this Weil generating series. When $\mathfrak{X}$ is the formal completion of a morphism $f$ from a smooth irreducible variety to the affine line, then its Weil generating series coincides (modulo normalization) with the motivic zeta function of $f$. When $\mathfrak{X}$ is the formal completion of $f$ at a closed point $x$ of the special fiber $f^{-1}(0)$, we obtain the local motivic zeta function of $f$ at $x$. In the latter case, the generic fiber of $\mathfrak{X}$ is the so-called analytic Milnor fiber of $f$ at $x$; we show that it completely determines the formal germ of $f$ at $x$.

A measurement of the branching ratio for the weak radiative decay of the lambda hyperon
Creators: name: Noble, Anthony James
Publisher: name: University of British Columbia
Year: 2011

description: In a measurement performed at the Brookhaven National Laboratory we have measured the branching ratio for the weak radiative decay of the ∧ hyperon. Our result, [formula omitted] is the second, but most precise, measurement of this quantity. It is in slight disagreement with the earlier measurement. Using a thick copper degrader, kaons of initial momentum 680 MeV/c were brought to rest in a liquid hydrogen target. Absorption of these kaons on target protons produced a ∧, either directly via the reaction K⁻p —> ∧ + π⁰, or indirectly via the reaction K⁻p —> Ʃ° + π° with subsequent decay, Ʃ° —> ∧ + [formula omitted]. The occurrence of each of these processes was established by observing the π° decay photons in a modular NaI detector, the Crystal Box. This detector was used to measure the energy and position of the final state particles, and hence allowed the topology of the event to be reconstructed. A wide range of theoretical techniques have been employed to estimate hyperon weak radiative decay amplitudes, including pole models, symmetry arguments, PCAC, and direct quark level calculations. These calculations must combine facets of the strong, weak and electromagnetic interactions. Hence, hyperon decays provide a testing ground for theorists to measure their ability to bring together these components in a relatively simple system. We discuss the implications of our result for a representative selection of theoretical estimates.

description: The three first sections contain an updated, not-so-short account of a partly original approach to spinor geometry and field theories introduced by Jadczyk and myself; it is based on an intrisic treatment of 2-spinor geometry in which the needed background structures do not need to be assumed, but rather arise naturally from a unique geometric datum: a vector bundle with complex 2-dimensional fibres over a real 4-dimensional manifold. The two following sections deal with Dirac algebra and 4-spinor groups in terms of two spinors, showing various aspects of spinor geometry from a different perspective. The last section examines particle momenta in 2-spinor terms and the bundle structure of 4-spinor space over momentum space.

title: The Enhancement of the Permanences as a Strategy for Recovery of the Inner Areas of the Marche region, Italy: The multilevel approach of territory, culture and people
Creators: name: Castagna, Benedetta
Publisher: name: University of Kent
Year: 2024

description: The depopulation of inner areas is a phenomenon impacting many areas of Italy. The lack of services, the difficult connection, the seismic and hydrogeological risk, the ageing population, and migration are some of the factors that contribute to this trend. 
This research aims to create a theoretical, methodological, and practical contribution to the debate on the depopulation of these territories and the preservation of cultural heritage. The approach is developed in the inner areas of the Marche in the centre of Italy. This is a unique region, with a fragmented territory and over 70% of the municipalities with less than 5,000 inhabitants. The fast and uncontrolled economic development of the 1980s led to an unrestrained movement of people accentuated by the 2008 financial crisis and the 2016 earthquake, with the mountainous areas further from the coast facing a steady decrease in inhabitants. 
This thesis explores the culture-led regeneration of the inner cities of the Marche, focusing on researching and enhancing heritage and historical knowledge. It critically identifies key elements of the historic city as catalysers for regeneration, emphasising that effective strategies require community participation at the centre of the design project. The approach is developed on three levels. The first is the macro level, which corresponds to the Marche region. Considering the complex historical evolution of the region and the fragmentation of the territory, the city of Ascoli Piceno represents the meso level within the inner areas as characterised by primary elements, which are catalysts for the culture-led regeneration of the city. Among these, a building has been selected as a case study on the micro-scale, the Palazzo Malaspina, a Renaissance palazzo in the city centre. 
This case study highlights the problem of buildings within the historical town, which, by contrast, have great potential. These buildings possess inherent potential to serve as resources for innovative territorial strategies. Involving the community in determining suitable functions for these structures can transform them into propelling permanence, playing a pivotal role in urban and regional transformations. The research builds a theoretical framework, a methodology based on different data collection methods for the study of the three levels and the definition of a strategic programme of local development. The outcomes identified through the case study provide an approach for regeneration projects of similar scope, areas, and regions, contributing to the debate on how best practices should involve all stakeholders in culture-led regeneration.

description: We have analysed the physical properties of z~4 Lyman Break Galaxies observed in the GOODS-S survey, in order to investigate the possible differences between galaxies where the Ly-alpha is present in emission, and those where the line is absent or in absorption. The objects have been selected from their optical color and then spectroscopically confirmed by Vanzella et al. (2005). From the public spectra we assessed the nature of the Ly-alpha emission and divided the sample into galaxies with Ly-alpha in emission and objects without Ly-alpha line (i.e. either absent or in absorption). We have then used the complete photometry, from U band to mid infrared from the GOODS-MUSIC database, to study the observational properties of the galaxies, such as UV spectral slopes and optical to mid-infrared colors, and the possible differences between the two samples. Finally through standard spectral fitting tecniques we have determined the physical properties of the galaxies, such as total stellar mass, stellar ages and so on, and again we have studied the possible differences between the two samples. Our results indicate that LBG with Ly-alpha in emission are on average a much younger and less massive population than the LBGs without Ly-alpha emission. Both populations are forming stars very actively and are relatively dust free, although those with line emission seem to be even less dusty on average. We briefly discuss these results in the context of recent models for the evolution of Lyman break galaxies and Ly-alpha emitters.

description: X-ray spectra of AGN often contain signatures indicative of absorption in multiple layers of gas whose ionization-state and covering fraction may vary with time. It has been unclear to date how much of the observed X-ray spectral and timing behavior in AGN can be attributed to variations in absorption, versus variations in the strengths of emission or reflection components. Diagnostics of the inner regions of AGN cannot be reliably performed until the origin of observed effects is understood. We investigate the role of the X-ray absorbers in the Seyfert 1 galaxy NGC 3516. Time-averaged and flux-selected spectroscopy is used to examine the behavior of NGC 3516 observed in Chandra HETG and XMM data from Oct 2006. New H-like and He-like emission and absorption features discovered in the Fe K regime reveal a previously unknown zone of circumnuclear gas in NGC 3516 with log xi ~ 4.3 and column density 1E23 cm^-2. A lower-ionization layer with log xi ~2 and of similar column density is confirmed from previous observations, this layer has a covering fraction around 50%, and changes in covering provide a simple explanation of a deep dip in the light curve that we interpret as an eclipse of the continuum due to passage of a cloud across the sight line within half a day. These inner zones of absorbing gas are detected to have outflow velocities in the range 1000-2000 km/s, this, and constraints on radial location are consistent with an origin as part of a disk wind in NGC 3516.

description: Ixodes nuttallianus Schulze, 1930
 This is a rare species in continental Southeast Asia, the main distributional area being the highlands of the Tibetan Plateau and Tibetan shrublands and meadows (Clifford et al. 1971, 1975; Guglielmone et al. 2014). In 1930, Schulze described Ixodes muntiaci from a single specimen originating from Mt. Victoria in the highland region of eastern Burma. This was synonymized with I. nuttallianus by Clifford et al. (1971). Schulze’s specimen remains the only one reported to date from Southeast Asia, although it is possible that this species is present in the mountainous regions of Myanmar bordering China and India. In those countries where it occurs, it is most commonly found at high altitudes of over 1,500 m to 3,640 m, where its wild hosts are associated with oak and tall fir forests and their accompanying vegetation, which may be required habitats for this species (Clifford et al. 1971). The hosts of adults are usually wild or domestic artiodactyl mammals in the families Bovidae and Cervidae, with dogs occasionally also being infested (Clifford et al. 1971). Ixodes nuttallianus is one of two known Southeast Asian members of the I. ricinus / persulcatus complex, the other being I. granulatus (Xu et al. 2003).
 The female is described in Kohls (1962), the female and male in Clifford et al. (1971).

description: We perform a direct finite nucleus calculation of the partial width of a bound Delta isobar decaying through the non-mesonic decay mode, Delta N -> NN. This transition is modeled by the exchange of the long ranged pi meson and the shorter ranged rho meson. The contribution of this decay channel is found to be approximately 60 % of the decay width of the Delta particle in free space. Considering the additional pionic decay mode, we conclude that the total decay width of a bound Delta resonance in nuclei is of the order of 100 MeV and, consequently, no narrow Delta nuclear states exist, contrary to recent claims in the literature. Our results are in complete agreement with microscopic many-body calculations and phenomenological approaches performed in nuclear matter.

description: Abstract: - Biofilm formation is a critical phenomenon in the context of chronic infections, significantly contributing to the persistence and resistance of bacterial pathogens against therapeutic interventions. Biofilms, which are structured communities of bacteria encased in a self-produced extracellular matrix, pose substantial challenges in clinical settings due to their inherent resistance to antibiotics and the host immune response. The mechanisms of biofilm formation involve multiple stages, including initial adhesion, maturation, and dispersion, and are influenced by factors such as extracellular polymeric substances (EPS) and quorum sensing. Notably, chronic infections associated with biofilms, including those found in cystic fibrosis, urinary tract infections, and chronic wounds, highlight the urgent need for effective therapeutic strategies. Traditional antibiotic treatments often fail to eradicate biofilm-associated bacteria, leading to persistent infections and significant morbidity. This article aims to explore the mechanisms underlying biofilm formation, the implications for chronic infections, and current therapeutic strategies aimed at disrupting biofilms to enhance treatment efficacy.

description: We study the response of an infinite, asymptotically static N=4 plasma to a generic localized source in the probe approximation. At large distances, the energy momentum tensor of the plasma includes a term which satisfies the constitutive relations of linearized hydrodynamics, but it can also include a non-hydrodynamical term which contributes at the same order as viscous corrections, or even at leading order in some cases. The conditions for the appearance of a laminar wake far behind the source and its relevance for phenomenological models used to explain di-hadron correlations are discussed. We also consider the energy momentum tensor near the source, where the hydrodynamical approximation can be expected to break down. Our analysis encompasses a wide range of sources which are localized in the bulk of AdS, including trailing strings, mesonic and baryonic configurations of strings, and point particles.

Optical study of the critical behaviour of pure fluids and binary mixtures
Creators: name: Närger, Ulrike
Publisher: name: University of British Columbia
Year: 2011

description: Optical techniques were used to study the critical behaviour of the pure fluids CHF₃, CCIF₃ and Xe, and binary mixtures He-Xe and nicotine + water. We find that for all these substances, the order parameter is described by a power law in the reduced temperature t = (Tc - T)/Tc with a leading exponent β = 0.327 ± 0.002. Also, we determine the first correction to scaling exponent to be Δ = 0.43 ± 0.02 for the pure fluids and Δ = 0.50 ± 0.02 for the He-Xe system. The coexistence curve diameter in CHF₃ and CCIF₃ exhibits a deviation from rectilinear diameter, in agreement with a modern theory which interprets this behaviour as resulting from three-body effects. In contrast, no such deviation is observed in Xe where, according to that theory, it should be more pronounced than in other substances. In the polar fluid CHF₃, the order parameter, isothermal compressibility and the chemical potential along the critical isotherm were simultaneously measured in the same experiment in an effort to ensure self-consistency of the results. From the data, two amplitude ratios which are predicted to be universal are determined: Γ+⃘ /Γ-⃘= 4.8 ± 0.6 and D⃘Γ+⃘B⃘δ-₁ = 1.66 ± 0.14. In the binary liquid system nicotine + water, the diffusivity was measured both by light scattering and by interferometry. The results agree qualitatively, but differ by a factor of ≈ 2. From the light scattering data, the critical exponent of the viscosity is found to be zη = 0.044 ± 0.008. The interferometric experiments on Xe and He-Xe furnish a direct way to maesure the effects of wetting: From the data, the exponent of the surface tension is found to be n = 1.24 ± 0.06. The similarity of the order parameter and compressibility in Xe and a He-Xe mixture containing 5% He indicate that the phase transition in this He-Xe mixture is of the liquid-gas type rather than the binary liquid type.

description: We propose a classical mechanism for the cosmic expansion during the radiation-dominated era. This mechanism assumes that the Universe is a two-component gas. The first component is a gas of ultra-relativistic "normal" particles described by an equation of state of an ideal quantum gas of massless particles. The second component consist of "unusual" charged particles (namely, either with ultra-high charge or with ultra-high mass) that provide the important mechanism of expansion due to their interaction with the "normal" component of the gas. This interaction is described by the Reissner--Nordström metric purely geometrically -- the ``unusual'' particles are modeled as zero-dimensional naked singularities inside spheres of gravitational repulsion. The radius of a repulsive sphere is inversely proportional to the energy of an incoming particle or the temperature. The expansion mechanism is based on the inflating of the "unusual" particles (of charge $Q$) with the drop of the temperature -- this drives apart all neutral particles and particles of specific charge $q/m$ such that ${sign}(Q) q/m \ge - 1$. The Reissner--Nordström expansion naturally ends at recombination. We discuss the range of model parameters within which the proposed expansion mechanism is consistent with the restrictions regarding quantum effects.

The graphs are obtained from $\mathbb{Z}^2$ by replacing every edge by a sufficiently large, but fixed number of edges in series. We prove that the linearly edge-reinforced random walk on these graphs is recurrent. Furthermore, we derive bounds for the probability that the edge-reinforced random walk hits the boundary of a large box before returning to its starting point.

title: British Press Responses to the American Civil War: A Case Study of The Times, The Economist and The Spectator, 1860 - 1862

description: This study investigates the formation of the editorial stances of three British newspapers, The Times, The Economist and The Spectator towards the American Civil War, beginning with the election of President Lincoln in November 1860 and ending two years later on the eve of the Emancipation Proclamation. The stances they adopted reflected the range of opinions which the British public held about the conflict. All three newspapers condemned the act of secession as illegitimate and expressed abhorrence for the institution of slavery which the secessionists sought to protect. However, their stances diverged markedly once secession appeared to have become irreversible without resort to civil war. Through a close analysis of the editorials in each newspaper, the study plots the trajectory of this divergence and analyses the reasons for it. It shows how, like much of the British press, The Times and The Economist came to see the American Civil War as a futile war of conquest on the Federal Government's part, which directly threatened Britain's cotton manufacturing industry, and appeared to be motivated by a desire to preserve the Union rather than to contain the extension of slavery. The only solution, in their view, was to allow the Confederacy to separate from the Union. This viewpoint had become entrenched by the time of the first major battle of war at Bull Run in July 1861 and was unaffected by Lincoln's Preliminary Emancipation Proclamation (PEP) the following year, which was seen as a cynical act of desperation. In these views, The Times and The Economist were closely in line with British government thinking, and, in spite of feeling that the conditions for recognition of the Confederacy had largely been met, they supported the Cabinet's decision in November 1862 not to intervene in the war with an offer of mediation. The Spectator, on the other hand, was in a minority of newspapers in Britain which supported the Union's right to use force to quell secession and never doubted that the issue of slavery was what the war was all about. While its support for the Washington government was not uncritical, and it shared some of the reservations of the other two newspapers about the PEP, it was firmly of the view that moral right in the conflict lay with the Union. For that reason, The Spectator opposed recognition on principle. Underlying explanations for the differences in viewpoint are considered, including differing perceptions of where British interests lay, misconceptions about American politics and constitutional law, and changing attitudes to emancipation and race towards the end of the antebellum period.

description: We present world average values for D0-D0bar mixing parameters x and y, CP violation parameters |q/p| and Arg(q/p), and strong phase differences δand δ_{Kππ}. These values are calculated by the Heavy Flavor Averaging Group (HFAG) by performing a global fit to relevant experimental measurements. The results for x and y differ significantly from zero and are inconsistent with no mixing at the level of 6.7 sigma. The results for |q/p| and Arg(q/p) are consistent with no CP violation. The strong phase difference δis less than 45 degrees at 95% C.L.

An exact fluid model for relativistic electron beams: The many moments case
Creators: name: Pennisi, Sebastiano
name: Carrisi, Maria Cristina
Publisher: name: arXiv
Year: 2007
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: An interesting and satisfactory fluid model has been proposed in literature for the the description of relativistic electron beams. It was obtained with 14 independent variables by imposing the entropy principle and the relativity principle. Here the case is considered with an arbitrary number of independent variables, still satisfying the above mentioned two principles; these lead to conditions whose general solution is here found. We think that the results satisfy also a certain ordering with respect to a smallness parameter $ε$ measuring the dispersion of the velocity about the mean; this ordering generalizes that appearing in literature for the 14 moments case.

description: Twelve flavonoids (1–12) including a new flavonol glycoside, hibiscetin 3-O-glucopyranoside-8-O-glucuronopyranoside, ten known galloylglucoses (13–22) and three known phenolic acids (23–25) were isolated from the aerial parts of Rhodiola rosea growing in Japan. Their chemical structures were elucidated by UV-vis spectra, LC-MS, HR-MS, acid hydrolysis, NMR, and/or HPLC, and TLC comparisons with authentic samples. Antioxidant activity of major 14 compounds was measured by H-ORAC method, and two flavonols, herbacetin 3-O-glucoside-8-O-glucuronide, and gossypetin 3-O-glucuronide-8-O-glucoside, showed the strongest activity. Moreover, chemical adaptation to severe alpine environment of R. rosea was discussed.
Flow interference effects between two circular cylinders of different diameters
Creators: name: Seto, Mae L.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis investigates different examples of action at a distance, namely the interaction of two circular cylinders of different diameters and the interaction of a cylinder with a wall in various arrangements. Action at a distance modifies both the lift and drag of each one of the objects. The fluid flow interaction between a circular cylinder (of diameter D) with a wall, and a circular cylinder with a smaller (¼D) circular cylinder at Reynolds numbers of ≈ 10,000 were of interest. Manifestations of the interactions include mutual changes in the lift and drag forces, phase, onset and frequency of vortex shedding on the circular cylinders/wall. A novel force measurement device for lift and drag of circular cylinders and a data acqusition system was built to realize the above experiments in a water towing tank. The system was capable of simultaneously measuring lift and drag on two circular cylinders with time resolution and correlating these measurements with flow field pictures. Measurements of the lift and drag and phase, onset and frequency of vortex shedding were taken on the large and small cylinder simultaneously as a function of the relative position between itself and the smaller cylinder as the two are towed. These measurements make it possible to map out the areas within the cylinders' sphere of influence and measure the intensity of this influence as a function of the distance between the two cylinders. Every quantity that was mutually altered by the presence of another cylinder is used as measurements of the area of influence for a circular cylinder. It was found in general that the forces act up to a distance of about 3 diameters in the lateral direction. It was also noted that pressure fluctuations at the vortex shedding frequency penetrate into the laminar flow region up to about 3D in the lateral direction. The results agree with existing results for wall/cylinder proximity experiments and flow interference between identical circular cylinders. A novel method to trigger the onset of vortex shedding for towing tanks was also discovered.

description: Carter derived the forms of the metric and the vector potentials of the space-times in which the relativistic Schrodinger equation for the motion of a charged particle separates. Here we show that on each `spheroidal' surface a rotation rate exists such that relative to those rotating axes the electric and magnetic fields are parallel and orthogonal to the spheroid which is thus an equipotential in those axes. All the finite Carter separable systems without magnetic monopoles or gravomagnetic NUT monopoles have the same gyromagnetic ratio as the Dirac electron.

Studies of spin-polarized hydrogen and deuterium at temperatures below 1 K using E.S.R.
Creators: name: Shinkoda, Ichiro
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis we describe the results of two sets of experiments on spin-polarized atomic hydrogen at temperatures below 1 K using a 115 GHz heterodyne ESR spectrometer. First, we have made measurements of the rates of the two-body recombination processes in spin-polarized atomic hydrogen gas and spin-polarized atomic deuterium gas in a 41 kG field. In the second set of experiments, we examined the ESR absorption line associated with the spin-polarized atomic hydrogen atoms adsorbed on surfaces of liquid helium. In hydrogen, a comparision of the measured recombination rates in 41 kG with the corresponding rates measured in different magnetic fields showed that an additional recombination process is activate for the conditions of these experiments. We demonstrate that this is due to a resonant recombination process via the (v,J) = (14,4) level of molecular hydrogen. In spin-polarized deuterium, we found that the recombination rate are much larger than the analogous rates in hydrogen, and therefore that atomic deuterium gas is much less stable than the hydrogen system under comparable conditions. We report the first observation and study of doubly spin-polarized deuterium, a gas in which both the deuteron and electron spins are aligned. At temperatures near 0.1 K, the absorption line of doubly spin-polarized H atoms changes drastically as a peak appears on both sides of the peak associated with the bulk atoms. We have shown that these new peaks are due to the atoms which are adsorbed onto the surface of the liquid helium film that coats the walls of the microwave cavity. The geometry dependent non-zero average magnetic dipolar field due to aligned spins on a planar surface results in a shift of the position of the ESR absorption lines. The lineshapes of the side peaks are very unusual and are best described as ramp-like. Even after extensive attempts to explain this lineshape, we still do not know what mechanism is responsible.

Ixodes ovatus

description: Ixodes ovatus Neumann, 1899
 Ixodes ovatus is found from Japan westward to northeastern India and Nepal, including Myanmar, Thailand, Lao PDR (Robbins et al. 1997) and Vietnam (Hoogstraal et al. 1973a; Kolonin 1992, 2009). Filippova (1977) considers this tick to be a representative of the Sino-Himalayan subregion of the Palearctic Region.
 Adults infest a range of large wild and domestic mammals and frequently attack humans (Sakai et al. 1976; Yamaguti and Takada 1981; Heath and Hardwick 2011). Immature stages are found predominantly on rodents.
 Ixodes ovatus occurs in a wide range of habitats, from low altitudes to 5,000 m above sea level (Fujimoto and Yamaguti 1987; Hoogstraal et al. 1973a). As there are structural differences characteristic of each developmental stage that are dependent on geographical location (Hoogstraal et al. 1973a), this taxon may represent a species complex. It is thus in need of revision (Guglielmone et al. 2009). Biological and ecological data for this species are available for Japanese populations (Fujisaki et al. 1976; Fujimoto 1990, 1987; Fujimoto et al. 1986; Fujimoto and Yamaguti 1990; Kakuda et al. 1989).
 All life history stages are illustrated in Yamaguti et al. (1971) and Hoogstraal et al. (1973a).
