Water maser follow-up of the methanol multibeam survey
Creators: name: Titmarsh, AM
Publisher: name: University Of Tasmania
Year: 2023

description: The Australia Telescope Compact Array has been used to search for 22-GHz water masers towards the 323 6.7-GHz methanol masers detected in the Methanol Multibeam survey between Galactic longitudes 341‚Äöv=¬¿ to 20‚Äöv=¬¿, through the Galactic centre, and we find water masers associated with 156 (‚Äöv†¬¿48 %). Methanol masers with associated water masers have a higher mean integrated luminosity than those without. In sources where both maser species are observed, the luminosities of the methanol and water masers are weakly correlated even after accounting for the partial correlation due to distance. We have inspected the GLIMPSE three colour images of the regions surrounding the masers and cross-matched the maser positions with existing catalogues of Extended Green Objects and Infrared Dark Clouds. We find more Extended Green Objects at sites where both methanol and water masers are present than at sites with only methanol masers, but no significant difference in the fraction embedded within Infrared Dark Clouds. Studying the mid-infrared colours from GLIMPSE, we found no differences between the colours of those sources associated with both methanol and water masers and those associated with just methanol. Analysis of the 1.1-mm thermal dust emission shows dust clumps associated with masers have greater 1.1-mm flux densities and higher column densities than those without. Dust clumps associated with both water and 6.7-GHz methanol masers are generally the most compact clumps followed by those associated with only methanol then the clumps without associated maser emission. Comparing the column density and dust mass calculated from the thermal dust emission at 870 ˜í¬¿m, we found no differences between those sources associated with both water and methanol masers and those with methanol only. At 870 ˜í¬¿m we found dust clumps at the very highest column densities (above ‚Äöv†¬¿ 1025 cm‚Äöv†v¿2) almost all had an associated methanol maser. We conclude that there is some evidence that protostars with both methanol and water masers are often older than those with only methanol, however, we suggest that the evolutionary phase traced by water masers is not as well defined as for 6.7-GHz methanol masers. Since water masers are collisionally pumped and often show emission further away from their accompanying YSO than the radiatively pumped 6.7-GHz methanol masers, it is likely that water maser properties are not as tightly correlated to the evolution of the parent YSO.

description: Accurate ab initio calculations of the energy levels of the superheavy elements Z=112 are presented. Relativistic Hartree-Fock and configuration interaction methods are combined with the many-body perturbation theory to construct the many-electron wave function for valence electrons and to include core-valence correlations. Two different approaches in which the element is treated as a system with two or twelve external electrons above closed shells are used and compared. Similar calculations for mercury are used to control the accuracy of the calculations. The results are compared with other calculations.

description: The purposes of the present study were to elucidate the risk and prognostic effect of second primary cancers (SPCs) development, as well as the factors influencing the prognosis of OC patients with SPCs. A statistically significant increase in SPCs risk was observed among OC patients during 2004–2015. The independent factors were used to construct the SPCs-prediction nomogram and the OS-prediction nomogram. Both nomogram were subjected to internal validation and performed well. OC patients with SPCs have a better prognosis than patients without SPCs. Propensity score matching (PSM) was applied to reduce confounding.

Energy Dissipation through Quasi-Static Tides in White Dwarf Binaries

description: We study tidal interactions in white dwarf binaries in the limiting case of quasi-static tides. The formalism is valid for arbitrary orbital eccentricities and therefore applicable to white dwarf binaries in the Galactic disk as well as globular clusters. In the quasi-static limit, the total perturbation of the gravitational potential shows a phase shift with respect to the position of the companion, the magnitude of which is determined primarily by the efficiency of energy dissipation through convective damping. We determine rates of secular evolution of the orbital elements and white dwarf rotational angular velocity for a 0.3 solar mass helium white dwarf in binaries with orbital frequencies in the LISA gravitational wave frequency band and companion masses ranging from 0.3 to 10^5 solar masses. The resulting tidal evolution time scales for the orbital semi-major axis are longer than a Hubble time, so that convective damping of quasi-static tides need not be considered in the construction of gravitational wave templates of white dwarf binaries in the LISA band. Spin-up of the white dwarf, on the other hand, can occur on time scales of less than 10Myr, provided that the white dwarf is initially rotating with a frequency much smaller than the orbital frequency. For semi-detached white dwarf binaries spin-up can occur on time scales of less than 1Myr. Nevertheless, the time scales remain longer than the orbital inspiral time scales due to gravitational radiation, so that the degree of asynchronism in these binaries increases. As a consequence, tidal forcing eventually occurs at forcing frequencies beyond the quasi-static tide approximation. For the shortest period binaries, energy dissipation is therefore expected to take place through dynamic tides and resonantly excited g-modes.

title: Communication to Reduce Embarrassment Between Individualistic and Collectivistic Cultures
Creators: name: Ganesan, Puvana
Publisher: name: Old Dominion University Libraries
Year: 1998

description:
lntercultural communication is an inherent aspect of life, and "as we move or are driven toward a global village and increasingly frequent cultural contact, we need more than simply greater factual knowledge of each other. We need, more specifically, to identify what might be called the 'rulebooks of meaning' that distinguish one culture from another" (Barnlund, 1975, p. 7).

This thesis sought to discover and contribute valuable content to this "rulebook of meaning" through intercultural communication between high context, collectivistic cultures and low-context, individualistic cultures in the situation of experiencing embarrassment. One goal of this study was to determine if distinct differences do exist between collectivistic and individualistic cultures in regards to ways of dealing or coping with embarrassment. Since specific embarrassment reduction strategies were identified for the two cultures, then in order to have a better understanding of the cultures, each must develop an understanding of how the other reacts and responds when embarrassed; thus adding an important component in the "rulebook of meanings."

description: Haemoglobin A1c (HbA1c) levels have been shown to be related to carotid artery plaques. However, studies on the relationship between HbA1c levels and carotid artery plaques in patients with coronary heart disease (CHD) are limited and inconsistent. Our objective was to examine the correlation between HbA1c levels and carotid artery plaques in patients with CHD. The study comprised 9275 Chinese adults with CHD from January 1, 2014, to September 30, 2020. HbA1c levels were assessed, and colour Doppler ultrasound was used to evaluate the carotid artery, including plaque presence, intima-media thickness, and plaque echo properties, to investigate the association between HbA1c and carotid plaque. A logistic regression model was used to assess the association between carotid artery plaques, carotid plaque echogenicity, and HbA1c. The HbA1c level of the plaque-present group was higher than that of the plaque-absent group [6.1 (5.6–7.2) vs. 5.8 (5.5–6.5), p < 0.001]. In multiple linear regression analysis, intima-media thickness was associated with HbA1c (p < 0.001). Logistic regression showed that a higher HbA1c level was associated with plaque incidence as well as hyperechoic and heterogeneous plaques (p < 0.001). These associations persist after adjusting for age, sex, blood pressure, lipid profiles, alcohol consumption, and tobacco exposure. HbA1c levels are notably associated with carotid artery plaque incidence, intima-media thickness, and plaque echogenicity in patients with CHD. These findings show that different levels of HbA1c may be an indicator for carotid artery plaques and thus, should be observed in patients with CHD.
A comparative study of lherzolite nodules in basaltic rocks from British Columbia
Creators: name: Littlejohn, Alastair Lewis
Publisher: name: University of British Columbia
Year: 2011

description: Lherzolite nodules in basaltic rocks from three localities in British Columbia include rocks of mantle origin and crystal cumulates. Partial chemical analyses show that the compositional ranges of the minerals are narrow for both major and minor elements and fall within the ranges reported for lherzolite nodules elsewhere. Each suite is characterised by a definite range of concentrations of some elements. Olivine in nodules from Castle Rock and Jacques Lake show fabrics resulting from deformation in the solid state prior to their incorporation into their host rocks but those from Nicola Lake are undeformed. The distribution of iron and magnesium between coexisting phases is examined using an ideal ionic solution model. Differences in the distribution coefficients between the suites are probably due to different temperature and pressure conditions at the source of the nodules. The distribution of iron and magnesium between coexisting spinel and olivine gives nominal temperatures of formation of 838°C for Nicola Lake nodules, 1085°C for Jacques Lake nodules and >l600°C for Castle Rock nodules. Differences among the suites in the distribution, of Ni, Co, Mn and Zn between coexisting silicates are independent of variations in composition and are apparently due to different conditions of formation. The Castle Rock and Jacques Lake lherzolites are residual fragments of the upper mantle left after extraction of an under-saturated basaltic liquid from parental mantle rock. The source of the Castle Rock nodules probably lies at greater depth than that of the Jacques Lake nodules. The Nicola Lake nodules are crystal cumulates and formed at an early stage of basalt genesis within the upper mantle or lower crust.

description: Optical two-dimensional Fourier-transformed (2DFT) spectroscopy is used to study the coherent optical response of potassium vapor in a thin transmission cell. Rephasing and non-rephasing spectra of the D1 and D2 transitions are obtained and compared to numerical simulations. Calculations using the optical Bloch equations gives very good agreement with the experimental peak strengths and line shapes. Non-radiative Raman-like coherences are isolated using a different 2DFT projection. Density-dependent measurements show distortion of 2DFT spectra due to pulse propagation effects.

Even though the transverse dimensions of the nanowires are much larger than the superconducting coherence length, the voltage-current characteristics of these nanowires at low temperatures are reminiscent of one-dimensional superconductors where quantum phase slips are associated with the origin of dissipation. We show that both the magnetoresistance oscillations and voltage-current characteristics observed in this work result from the granular structure of our nanowires.

The influence of crop nutrition on the quality of onion bulbs destined for export markets
Creators: name: Smallbon, TR
Publisher: name: University Of Tasmania
Year: 2023

description: The key export onion markets demand consistent supply of high-quality bulbs with long storage life from Tasmania. Supplying these market requirements challenges our body of knowledge relating to bulb quality. This study sought to address the potential links between crop nutrition and bulb quality by surveying thirty-four commercial onion crops across seven soil types. Plant tissue concentrations were recorded through key growth and development stages from two true leaf to harvest. These results were then related to yield and bulb quality attributes through multivariate analyses. The findings were compared with existing literature on onion bulb production and in many cases, provides new information on elemental tissue concentrations at a number of growth stages not previously reported. The survey established linkages between element concentration in plant tissue and bulb quality, particularly apropos to skin loss. Here a relationship of bulb moisture content below 87.6% together with tissue concentrations of molybdenum lower than 0.047 ppm was associated with a decrease in skin loss. In contrast, nitrate levels greater than 20 ppm were associated with higher levels of skin loss and this effect was exacerbated if bulb tissue sulphur concentrations also exceeded 0.34%. Expanding on the quality linkages established from the initial survey, factorial experiments were then undertaken across four sites with two cultivars to explore the interaction of applied sulphur, molybdenum and nitrogen on onion plant elemental composition and bulb skin loss. Bulb robustness was assessed by subjecting harvested bulbs to multiple handling assessments over a five-month period. Amending the base fertiliser programme with ammonium sulphate increased sulphur concentrations in the bulb tissue of both cultivars, and nitrogen levels in Regular Creamgold. Supplementation with foliar applied molybdenum also increased concentrations of this element within this cultivar. This study has complemented existing knowledge and added new data for some onion growth stages not previously reported. This improves scientific understanding of the range of nutritional element concentrations found in high yielding onion crops and has provided evidence that consideration of plant nutrition not only applies to crop yield, but also to the quality of the onion bulbs produced.

description: The positronium state in quartz is described by a linear superposition of two states: the first describing the free positron in the crystal and the second corresponding to a positronium Bloch wavefunction in the lattice. The condition for positronium formation in the electron gas is deduced by using variational calculations of the positron binding energy to the electron system. The self annihilation parameter $κ$ introduced in positron lifetime experiments can be properly justified by using the mixed state. A variational method to calculate $κ$ is proposed.

Age-related cognitive decline : the roles of physical activity and the apolipoprotein E e4 allele
Creators: name: Conley, GA
Publisher: name: University Of Tasmania
Year: 2023

description: We examined the effects of physical activity and the apolipoprotein E e4 allele (APOEe4) on age-related cognitive decline amongst a sample of cognitively normal middle-aged and older adults. Forty-seven participants (76.6% female; 23.4% male) aged 50-71 at baseline (`M` = 60.0, `SD` = 5.8) wore an accelerometer to record total weekly level of physical activity. Participants also underwent APOE genotyping and annual cognitive tests assessing long-term memory and learning, working memory, and executive functioning through the Tasmanian Healthy Brain Project. We conducted a series of three-way mixed analyses of variance to test for interaction effects between physical activity status (active; inactive), APOEe4 status (carrier; non-carrier), and assessment phase (1; 2; 3; 4) on performance on each of the cognitive tests. For all cognitive tests, there were no consistent effects of physical activity, no consistent effects of APOEe4, and no significant interaction effects between physical activity, APOEe4, and phase of assessment. Findings suggest that physical activity, APOEe4, or combinations of the two do not influence nonpathological age-related cognitive decline. Future research would benefit from examining the possibility that APOEe4 may be detrimental to cognitive decline for individuals that carry two copies of the allele, and from examining whether lifetime levels of physical activity or specific types of physical activity influence age-related cognitive decline.

description: We study the unexpected high flexibility of short dsDNA which recently has been reported by a number of experiments. Via the Langevin dynamics simulation of our Breathing DNA model, first we observe the formation of bubbles within the duplex and also forks at the ends, with the size distributions independent of the contour length. We find that these local denaturations at a physiological temperature, despite their rare and transient presence, can lower the persistence length drastically for a short DNA segment in agreement with experiment.
title: Crosswords at a Crossroad: The Puzzle Turns 100. What Is the Clue to its Survival?
Creators: name: Feigenbaum, Lynn J.
Publisher: name: Old Dominion University Libraries
Year: 2013

description: Celebrating the 100th anniversary of the crossword on Dec. 21, 2013 will be a dedicated, demanding and outspoken following - an online community that may be the key to its future as a popular American pastime. The crossword puzzle has always had a tight-knit core of fans, even in its earliest years. But, for the most part, doing a crossword was a solitary pursuit. That has changed with the advent of a burgeoning fan community on the internet, a virtual community of crossword enthusiasts. It is not far-fetched to regard the saga of the crossword as a microcosm of modem community building, a case history on how a traditional pastime can adapt to new media.

In this paper, my intent is to show - through research, interview and my own longtime amateur participation in puzzling - the importance of community to a leisure-time pursuit; and specifically how cyber-fans use their collective voice to influence crossword output both creatively and economically. Creatively because blogs and other web resources have raised the volume and reach of an active crossword fan base, allowing it to exert more far-reaching pushback on puzzle creators and content. Economically because with the dramatic decline of the crossword's longtime medium, the print newspaper, this traditionally paper-and-pencil pastime is moving online.

Complicating the discussion is a growing generation gap, a tug-of-war between younger and older puzzlers for what they see as relevant and acceptable content. Thus, the crossword is at a crossroad: an older generation forms a core part of the fan base while younger puzzlers are charged with adapting and shaping the crossword for survival in the future .

Detailed bedrock geology of the brenda copper- molybdenum mine, peachland, b.c.
Creators: name: Oriel, William Michael
Publisher: name: University of British Columbia
Year: 2011

description: Detailed mapping of the bedrock geology of the Brenda copper-molybdenum deposit has revealed a consistent sequence of geological events. Consolidation of the quartz diorite host rock that forms Brenda stock was followed by intrusion of small pegmatite and aplite dikes that probably relate to a residual fraction of the parent magma. Age dating of various quartz diorites (White and Harakal, unpublished) indicates that magma solidification occurred about 176 m.y. A concentration of biotite model ages at about 146 m.y. seems best interpreted as the time of ore mineralization. Mineralization occurred at the beginning of a continuous sequence of related structural events. All mineralized ore fractures and younger shears, faults and intramineral dikes exhibit similar, strongly preferred orientations that are unlike orientations of felsic dikes or primary foliations in the quartz diorite host rock. The ore occurs entirely in fractures as products of three sequential overlapping phases of mineralization and consists almost entirely of the ore minerals chalcopyrite and molybdenite with quartz gangue predominanting. Hydrothermal alteration products exist mostly as thin envelopes of potassium feldspar and/or biotite and propylitic alteration. Large argillic alteration zones also exist, however, and are associated commonly with extensively sheared zones. An effort was made at finding a zoning pattern of ore minerals, minor elements and alteration minerals. Ore mineral zoning in the classical sense appears to be absent at Brenda. Metal grades show a crude zonal distribution that correlates directly with density of ore fractures, Hydrothermal alteration minerals and minor elements in chalcopyrite also lack any obvious systematic zonation pattern on the scale of the mine pit. Intramineral dikes of various textures and compositions have been dated at about 130 m.y. They formed after ore mineralization yet before late minor veining not associated with ore-producing veins.
Universal emission intermittency in quantum dots, nanorods, and nanowires

description: Virtually all known fluorophores, including semiconductor nanoparticles, nanorods and nanowires exhibit unexplainable episodes of intermittent emission blinking. A most remarkable feature of the fluorescence intermittency is a universal power law distribution of on- and off-times. For nanoparticles the resulting power law extends over an extraordinarily wide dynamic range: nine orders of magnitude in probability density and five to six orders of magnitude in time. The exponents hover about the ubiquitous value of -3/2. Dark states routinely last for tens of seconds, which are practically forever on quantum mechanical time scales. Despite such infinite states of darkness, the dots miraculously recover and start emitting again. Although the underlying mechanism responsible for this phenomenon remains an enduring mystery and many questions remain, we argue that substantial theoretical progress has been made.

The psychological health and wellbeing of Australian healthcare professionals
Creators: name: Cragg, KJ
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this study was to predict the psychological outcomes (compassion fatigue, job satisfaction, compassion satisfaction, resilience) of Australian healthcare professionals using a salutogenic approach. Between-group differences in health professional's psychological wellbeing were examined, as were possible moderation effects between the significant work environment predictors and pathogenic outcomes. A total of 380 participants accessed an online survey which measured ways of coping, resilience, job satisfaction, professional quality of life, and psychological distress. Work environment factors (nature of work, process, pay, benefits), adaptive (problem solving, acceptance, social support) and maladaptive (escape avoidance, confrontative coping, responsibility, self-control) coping strategies, and psychological distress were among the variables contributing to health professional's psychological outcomes. Between-group differences were limited to a select few categories (sex, relationship status, mental health status). All salutogenic outcomes (compassion satisfaction, job satisfaction, resilience) moderated the relationship between at least one predictor and pathogenic outcome. Future research is needed to confirm the results of the present study and to evaluate the effectiveness of proposed interventions.

description: The high pericenter velocities (up to a few percent of light) of the S stars around the Galactic-center black hole suggest that general relativistic effects may be detectable through the time variation of the redshift during pericenter passage. Previous work has computed post-Newtonian perturbations to the stellar orbits. We study the additional redshift effects due to perturbations of the light path (what one may call "post-Minkowskian'' effects), a calculation that can be elegantly formulated as a boundary-value problem. The post-Newtonian and post-Minkowskian redshift effects are comparable: both are O(beta^3) and amount to a few km/s at pericenter for the star S2. On the other hand, the post-Minkowskian redshift contribution of spin is O(beta^5) and much smaller than the O(beta^4) post-Newtonian effect, which would be approximately 0.1km/s for S2.

description: A convenient tool for detecting iron ions in subcellular structures is desired for better understanding its roles in biological systems. In this work, a new Fe3+ sensor, 2-(2-((1-(6-acetylpyridin-2-yl)ethylidene)amino)ethyl)-3',6'-bis(diethylamino)spiro[isoindoline-1,9'-xanthen]-3-one (RhPK), which operates across the entire cellular pH range and is capable of unambiguously detecting Fe3+ ion in live human cells at subcellular resolution, is reported. The sensor exhibits high selectivity and sensitivity toward Fe3+ with a rapid fluorescence response and a 12-fold increase in intensity upon the addition of 1 equivalent Fe3+ at pH 7.3. RhPK forms a 1:1 complex with Fe3+ with an apparent binding constant 1.54 × 107 M−1 and a detection limit of 50 nM. The sensor is stable between pH 4.2 and 9.0 and operates across the whole cellular pH range. Cell imaging demonstrates the ability of the sensor to unambiguously detect basal level Fe3+ as well as its dynamic changes in real-time in live cells at subcellular resolution, with one labile Fe3+ pool identified in mitochondria in human primary fibroblast (ws1) cells for the first time and two Fe3+ pools confirmed in mitochondria and endo/lysosomes in human SH-SY5Y neuroblastoma cells, suggesting different cell types have distinctive Fe3+ storage in subcellular compartments. The RhPK probe is powerful for rapid and sensitive bioimaging of Fe3+ at subcellular level, enabling the unambiguous detection of labile Fe3+ pools at the entire cellular pH range, which is of great significance to understand the biological chemistry of Fe3+ and its roles in physiological processes and diseases.
How complex is the obscuration in AGN? New clues from the Suzaku monitoring of the X-ray absorbers in NGC7582

description: We present the results of a Suzaku monitoring campaign of the Seyfert 2 galaxy, NGC7582. The source is characterized by very rapid (on timescales even lower than a day) changes of the column density of an inner absorber, together with the presence of constant components arising as reprocessing from a Compton-thick material. The best fitting scenario implies important modifications to the zeroth order view of Unified Models. While the existence of a pc-scale torus is needed in order to produce a constant Compton reflection component and an iron K$α$ emission line, in this Seyfert 2 galaxy this is not viewed along the line of sight. On the other hand, the absorption of the primary continuum is due to another material, much closer to the BH, roughly at the distance of the BLR, which can produce the observed rapid spectral variability. On top of that, the constant presence of a $10^{22}$ cm$^{-2}$ column density can be ascribed to the presence of a dust lane, extended on a galactic scale, as previously confirmed by Chandra. There is now mounting evidence that complexity in the obscuration of AGN may be the rule rather than the exception. We therefore propose to modify the Unification Model, adding to the torus the presence of two further absorbers/emitters. Their combination along the line of sight can reproduce all the observed phenomenology.

Comparison of structure and transport properties of concentrated hard and soft sphere fluids

description: Using Newtonian and Brownian dynamics simulations, the structural and transport properties of hard and soft spheres have been studied. The soft spheres were modeled using inverse power potentials ($V\sim r^{-n}$, with $1/n$ the potential softness). Although the pressure, diffusion coefficient and viscosity depend at constant density on the particle softness up to extremely high values of $n$, we show that scaling the density with the freezing point for every system effectively collapses these parameters for $n\geq 18$ (including hard spheres), for large densities. At the freezing points, the long range structure of all systems is identical, when the distance is measured in units of the interparticle distance, but differences appear at short distances (due to the different shape of the interaction potential). This translates into differences at short times in the velocity and stress autocorrelation functions, although they concur to give the same value of the corresponding transport coefficient (for the same density to freezing ratio); the microscopic dynamics also affects the short time behaviour of the correlation functions and absolute values of the transport coefficients, but the same scaling with the freezing density works for Newtonian or Brownian dynamics. For hard spheres, the short time behaviour of the stress autocorrelation function has been studied in detail, confirming quantitatively the theoretical forms derived for it.

A geological reconnaissance of the dellwood seamount area, northeast pacific ocean, and its relationship to plate tectonics

description: The Dellwood Seamount Area, an area of approximately 10,000 square km., about 185 km. west of the northern tip of Vancouver Island is located at or near the northernmost end of the Juan de Fuca plate. The main purpose of the study was to test the hypothesis that the Dellwood Knolls mark the site of a short spreading segment connected to the Explorer Spreading Segment at one end by a transform fault trending along the southwestern slope of Paul Revere Ridge; and meeting the Queen Charlotte right lateral transform fault at the other end. An analysis of more than 950 km. of continuous seismic reflection profiles, in conjunction with other geophysical data, shows that (i) the Revere -Dellwood fault zone is a dextral transform fault zone connecting the Explorer and Dellwood spreading segments. (ii) The Queen Charlotte transform fault dies out at the southeastern end of the Scott Channel near the northeastern end of the Dellwood Spreading Segment. (iii) In the channel between the Dellwood Knolls (one of two possible locations of the Dellwood Spreading Segment), the sediments and volcanic basement are cut by normal faults, a feature which is characteristic of spreading centres with median valleys. The heat flow in this channel and in the Revere - Dellwood fault zone is high. (iv) The lower continental slope sediments west of Queen Charlotte Sound is faulted and crumpled and may be the northerly extension of the Scott Islands fault, zone and a site of slow contemporaneous or recently ceased subduction. The deformation of the thick turbidite sequence in the Winona Basin may also be due to subduction. Basalt from the area is chemically intermediate between tholeiitic and alkalic types. That from the Northwest Dellwood Knolls, however, is least differentiated and less than 1 myr. old in contrast to basalt from the sediment-draped Southeast Dellwood Knolls, the latter basalt having Mn-coating up to 50 mm. thick and is thus relatively old. This suggests that spreading may be occurring at the Northwest Dellwood Knolls and not in the channel between the knolls. The texture of basalts from the Dellwood Seamount Range vary depending on size of pillow and depth below pillow surface, but the mineralogy is essentially similar. An unusual rock probably best described as a plagio-clase-olivine basalt porphyry was also recovered from the Dellwood Seamount Range. Non-volcanic rocks recovered include glacial erratics, an authigenic sandstone comprising glacial fragments in an iron-rich cement, a laminated limonitic sediment and manganese nodules. The Dellwood Spreading Segment may have originated by left lateral transcurrent offset from the Explorer Spreading Segment, the offset caused by a change in the direction of motion of the Juan de Fuca plate.

description: We calculate rigorous lower bounds for the ground state degeneracy per site, $W$, of the $q$-state Potts antiferromagnet on slabs of the simple cubic lattice that are infinite in two directions and finite in the third and that thus interpolate between the square (sq) and simple cubic (sc) lattices. We give a comparison with large-$q$ series expansions for the sq and sc lattices and also present numerical comparisons.
