description: Wheat production plays an important role in Morocco. Current wheat forecast systems use weather and vegetation data during the crop growing phase, thus limiting the earliest possible release date to early spring. However, Morocco's wheat production is mostly rainfed and thus strongly tied to fluctuations in rainfall, which in turn depend on slowly evolving climate dynamics. This offers a source of predictability at longer time scales. Using physically guided causal discovery algorithms, we extract climate precursors for wheat yield variability from gridded fields of geopotential height and sea surface temperatures which show potential for accurate yield forecasts already in December, with around 50% explained variance in an out-of-sample cross validation. The detected interactions are physically meaningful and consistent with documented ocean-atmosphere feedbacks. Reliable yield forecasts at such long lead times could provide farmers and policy makers with necessary information for early action and strategic adaptation measurements to support food security. ©2020.

description: We examine nonparametric dose-finding designs that use toxicity estimates based on all available data at each dose allocation decision. We prove that one such design family, called here "interval design", converges almost surely to the maximum tolerated dose (MTD), if the MTD is the only dose level whose toxicity rate falls within the pre-specified interval around the desired target rate. Another nonparametric family, called "point design", has a positive probability of not converging. In a numerical sensitivity study, a diverse sample of dose-toxicity scenarios was randomly generated. On this sample, the "interval design" convergence conditions are met far more often than the conditions for one-parameter design convergence (the Shen-O'Quigley conditions), suggesting that the interval-design conditions are less restrictive. Implications of these theoretical and numerical results for small-sample behavior of the designs, and for future research, are discussed.

The legacy of domestic violence : how the dynamics of abuse continue beyond separation
Creators: name: Pitman, TM
Publisher: name: University Of Tasmania
Year: 2023

description: In Australia, social and legal trends towards shared parenting after separation coincide with statistics conveying domestic violence as the single biggest health risk to women of reproductive age (UNPFR, 2005). Such statistics rely on the reporting of physical violence, yet there is a growing recognition that domestic violence is best conceptualised as a pattern of coercive control (Stark, 2007) that may include only minor, if any, physical violence (Johnson, 2008). An important concern for the Australian social work profession should be a coherent ability to identify and respond to domestic violence in order to ensure the protection of women and children in the trend towards shared-parenting post separation. This thesis explored women's experiences of post-separation shared parenting arrangements and the aspects of abuse which persisted beyond separation. The study was conducted from a feminist standpoint. Thirty (30) women were recruited using non-probability purposive and snowballing sampling procedures. Semi-structured, in-depth interviews explored their pre- and post-separation experiences of abuse from the fathers of the children. This data was then thematically analysed. The findings of this study show that there was a commonality of dynamics underlying the relationship each woman had with the father of their children. Despite the women's resistance, these dynamics gave rise to shared experiences of oppression both pre- and post-separation. The dynamics are conceptualised as a web of abuse emanating from their partners' attitudinal and behavioural style. A parallel is drawn between the web of abuse and a process of colonisation. Colonisation helps clarify the relentless and pervasive pattern of boundary violations experienced by the women both pre- and post-separation. It also explains the extent of the women's post-separation difficulties irrespective of the presence, form or intensity of shared parenting arrangements. The consequences of conceptualising domestic violence independently of physical violence and as a colonising process are discussed with regard to the implications for counselling, research, the socio-legal response, and social work knowledge and practice. A conclusion drawn from this study suggests that critical to the anti-oppressive practice of social workers in the field of domestic violence is their ability to detect and disrupt colonising attitudes and behaviours. Collusion with such attitudes and behaviours seriously undermines the value of our profession for women and children who are at risk of abuse.

Triangulated Loop Quantum Cosmology: Bianchi IX and inhomogenous perturbations

description: We develop the "triangulated" version of loop quantum cosmology, recently introduced in the literature. We focus on the "dipole" cosmology, where space is a three-sphere and the triangulation is formed by two tetrahedra. We show that the discrete fiducial connection has a simple and appealing geometrical interpretation and we correct the ansatz on the relation between the model variables and the Friedmann-Robertson-Walker scale factor. The modified ansatz leads to the convergence of the Hamiltonian constraint to the continuum one. We then ask which degrees of freedom are captured by this model. We show that the model is rich enough to describe the (anisotropic) Bianchi IX Universe, and give the explicit relation between the Bianchi IX variables and the variables of the model. We discuss the possibility of using this path in order to define the quantization of the Bianchi IX Universe. The model contains more degrees of freedom than Bianchi IX, and therefore captures some inhomogeneous degrees of freedom as well. Inhomogeneous degrees of freedom can be expanded in representations of the SU(2) Bianchi IX isometry group, and the dipole model captures the lowest integer representation of these, connected to hyper-spherical harmonic of angular momentum j=1.

description: Observed metallicities of globular clusters reflect physical conditions in the interstellar medium of their high-redshift host galaxies. Globular cluster systems in most large galaxies display bimodal color and metallicity distributions, which are often interpreted as indicating two distinct modes of cluster formation. The metal-rich and metal-poor clusters have systematically different locations and kinematics in their host galaxies. However, the red and blue clusters have similar internal properties, such as the masses, sizes, and ages. It is therefore interesting to explore whether both metal-rich and metal-poor clusters could form by a common mechanism and still be consistent with the bimodal distribution. We present such a model, which prescribes the formation of globular clusters semi-analytically using galaxy assembly history from cosmological simulations coupled with observed scaling relations for the amount and metallicity of cold gas available for star formation. We assume that massive star clusters form only during mergers of massive gas-rich galaxies and tune the model parameters to reproduce the observed distribution in the Galaxy. A wide, but not entire, range of model realizations produces metallicity distributions consistent with the data. We find that early mergers of smaller hosts create exclusively blue clusters, whereas subsequent mergers of more massive galaxies create both red and blue clusters. Thus bimodality arises naturally as the result of a small number of late massive merger events. This conclusion is not significantly affected by the large uncertainties in our knowledge of the stellar mass and cold gas mass in high-redshift galaxies. The fraction of galactic stellar mass locked in globular clusters declines from over 10% at z>3 to 0.1% at present.

Macrofossil evidence for Quaternary plant extinction and vegetation change in western Tasmania
Creators: name: Jordan, GJ
Publisher: name: University Of Tasmania
Year: 2023

description: Macrofossils from Pleistocene sediments in western Tasmania are investigated in order to reconstruct vegetation from this critical period. in the history of Australia's vegetation. The microfossil record shows that many taxa. notably the common Tertiary taxa Nothofagus subgenus Brassospora. Araucariaceae. Dacrycarpus and Dacrydium. were present in western Tasmania during the Latest Pliocene or Earliest Pleistocene but are now extinct from Tasmania. Most of these taxa are likely to have been rainforest species, but some may have been from sclerophyll vegetation (e.g. Beauprea). A few of these persisted into the Early-Middle Pleistocene and only Quintinia to the Late Pleistocene. Macrofossils of now globally and regionally extinct taxa occur in the Early Middle Pleistocene Regatta Point sediments. Most of these extinct taxa are not distinct in the relatively good microfossil record of that area. Some clearly sclerophyllous taxa have become extinct e.g. Banksia strahanensis and Oxylobium sp. nov. Rainforest taxa no longer occurring in Tasmania have affinities with species from temperate New Zealand (e.g. Quintinia sp. nov.), montane north-eastern New South Wales and Queensland (e.g. Rubus cf. moorei forma glabra, aff. Austromyrtus and Laurophyllum sp.). Macrofossils of only one extinct species occur in sediments younger than Regatta Point: Banksia kingii from the Late Pleistocene Melaleuca Inlet sediments. Local climatic and vegetation reconstructions for the times of deposition are made -for the Regatta Point, the middle Pleistocene Regency and the late Pleistocene Melaleuca Inlet sediments based on floristics. Vegetation reconsttuctions include analysis of diversity using both floristics and a modified rarefaction method. Both climatic and vegetation reconstructions are interpreted in terms of taphonomic studies both in this work and elsewhere. Regression modelling of the leaf size of N. cunninghamii from modern forest floor litter against BIOCLIM synthetic climatic parameters indicates that leaf length is well correlated to temperature of the growing season and palaeo-temperatures are estimated for the fossil floras. The extinctions are interpreted in terms of the climatic and vegetation reconstructions of the sites and broader scale knowledge of late Cenozoic climate, vegetation and glacial history. Many Tertiary taxa survived the climatic disruptions of the Early Pleistocene, but probably become extinct directly or indirectly due to the glaciations of the Middle Pleistocene. Rainforest diversity is lower now than during the Early Pleistocene, but the results are ambiguous for overall diversity. There is no reason to suspect that Tasmania could not support more diverse rainforest under modern conditions.
The osmotic and ionic regulatory capacities of the kidney of the harbor seal, Phoca vitulina
Creators: name: Tarasoff, Frederick John
Publisher: name: University of British Columbia
Year: 2011

description: The mechanisms of osmotic and ionic regulation in marine mammals are of interest because of the apparent lack of "fresh" water in their environment. Previous investigation on the harbor seal, (Phoca vitulina, L.), generally indicated that the seal can obtain all the water it requires from its food. However, some dispute still exists as to whether the seal may ingest sea water along with its food and conserve water by concentrating ions and excreting them with a net water gain. The effects of a 16-hour period with no fluids and also of intubation with varying amounts of distilled water and varying amounts and concentrations of sea water were determined. The concentrations of sodium, chloride and potassium ions as well as the osmotic pressures of plasma and urine were measured for the periods before and after intubation. The results of this study are discussed with respect to published data and proposed mechanisms of osmotic and ionic regulation by the kidney. The findings indicate, as suggested by others, that the seal does not gain any substantial amount of water from sea water ingestion.
Red Antarctic : Soviet interests in the south polar region prior to the Antarctic Treaty 1946-1958
Creators: name: Gan, I

description: Despite the fact that in 2006 Russia celebrated the golden jubilee of uninterrupted research on the Antarctic continent, there has been no attempt to eXarJ.1ine the history of Soviet interest in the Antarctic in the English language. While Russian authors have written histories of Soviet Antarctic expeditions based on expedition reports, this study analyses Russian and Australian archival material, most of which has not been accessed before. After the end of World War 11, the Union of Soviet Socialist Republics providentially acquired a complete German whaling flotilla as war reparations. From the time of the flotilla's first whaling operations in the Southern Ocean, a physical Soviet presence in the Antarctic was assured. The later US proposal for a solution to conflicting Antarctic territorial claims which . attempted to exclude Soviet participation and the proposal of scientists for an International Geophysical Year (IGY) in 1957 - 1958 not only stimulated Soviet resolve to obtain a foothold on the icy continent, but provided the opportunity to do so. The main. body of the study deals with Soviet political and logistical preparations for their IGY operations in Antarctica and their thrust into the interior of the continent to establish observatories, all situated in the Australian Antarctic Territory. In a time of Cold War tensions and unresolved Antarctic claims, the Anglo-Arnerican world (and the Australian government in particular) was especially wary of Soviet intentions. In the fimll months of the IGY, the political and scientific future of the Antarctic was being shaped, with new proposals for an international Antarctic regime and proposals for continuation of Antarctic research being discussed. This study explores the thinking of political and scientific decision makers that helped mould Soviet Antarctic policy during this time and demonstrates that the two perspectives did not necessarily coincide. Whatever the divergences of opinion, the evidence indicates that from the day the Soviets set foot on the Antarctic continent, they had no intention of leaving.

description: Mesospheric winds from three longitudinal sectors at 65°N and 54°N latitude are combined to diagnose the zonal wave numbers (m) of spectral wave signatures during the Southern Hemisphere sudden stratospheric warming (SSW) 2019. Diagnosed are quasi-10- and 6-day planetary waves (Q10DW and Q6DW, m = 1), solar semidiurnal tides with m = 1, 2, 3 (SW1, SW2, and SW3), lunar semidiurnal tide, and the upper and lower sidebands (USB and LSB, m = 1 and 3) of Q10DW-SW2 nonlinear interactions. We further present 7-year composite analyses to distinguish SSW effects from climatological features. Before (after) the SSW onset, LSB (USB) enhances, accompanied by the enhancing (fading) Q10DW, and a weakening of climatological SW2 maximum. These behaviors are explained in terms of Manley-Rowe relation, that is, the energy goes first from SW2 to Q10DW and LSB, and then from SW2 and Q10DW to USB. Our results illustrate that the interactions can explain most wind variabilities associated with the SSW. © 2020. The Authors.
New Limits on an Intermediate Mass Black Hole in Omega Centauri: I. Hubble Space Telescope Photometry and Proper Motions

description: We analyze data from the Hubble Space Telescope's Advanced Camera for Surveys of the globular cluster Omega Cen. We construct a photometric and proper-motion catalog using the GO-9442, GO-10252, and GO-10775 data sets. The 2.5- to 4-year baseline between observations yields a catalog of some 10^5 proper motions, with 53,382 high-quality measurements in a central field. We determine the cluster center to ~1-arcsecond accuracy using two different star-count methods, and a completely independent method using 2MASS images. We also determine the kinematical center of the proper motions, which agrees with the star-count center to within its uncertainty. The proper-motion dispersion of the cluster increases gradually inwards, but there is no variation in kinematics with position within the central ~15 arcsec: there is no dispersion cusp and no stars with unusually high velocities. We measure for the first time in any globular cluster the variation in proper-motion dispersion with mass along the main sequence, and find the cluster not yet to be in equipartition. Our proper-motion results do not confirm the arguments put forward by Noyola, Gebhardt & Bergmann to suspect an intermediate-mass black hole (IMBH) in Omega Cen. In Paper II we present new dynamical models for the high-quality data presented here, with the aim of putting quantitative contraints on the mass of any possible IMBH.

Ice dreaming : reading whiteness in Kim Scott's 'Benang: from the heart'
Creators: name: Harman, Kristyn
Publisher: name: University Of Tasmania
Year: 2023

description: Through a close reading of Kim Scott's Benang: from the heart, this thesis interrogates what whiteness in an Australian colonial context looks like from an Aboriginal perspective. Its central proposition is that Scott's narrator, Harley, discovers whiteness as a consequence of discovering his Aboriginality. It suggests whiteness is imbued with a power that arises through its invisibility and its ability to racialise and circumscribe non-white others. When this process is reversed, and whiteness is made visible, its power is diminished. Harley (re)places whiteness into an Aboriginal paradigm from within which he imagines a syncretic future for Australia.

description: In this paper we discussed the application and the implementation of multipath routing and multiple description coding (MDC) extension of OLSR, called MP-OLSR. It is based on the link state algorithm and employs periodic exchange of messages to maintain topology information of the networks. In the mean time, it updates the routing table in an on-demand scheme and forwards the packets in multiple paths which have been determined at the source. If a link failure is detected, the algorithm recovers the route automatically. Concerning the instability of the wireless networks, the multiple description coding is used to improve reliability of the network transmission, and several methods are proposed to allocate the redundancy in different paths. The simulation in NS2 shows that the new protocol can effectively improve the performance of the networks. The implementation of MP-OLSR is also proposed in the end.
Superplasticity in a dilute zinc aluminum alloy
Creators: name: Cook, Richard Charles
Publisher: name: University of British Columbia
Year: 2011

description: The system Zn-0.2 wt. % Al has been investigated to determine under what conditions of strain rate, grain size and temperature the phenomenon of superplasticity may be observed. The analysis and experimental conditions were based on established procedures which have been applied to known superplastic alloys. However the continually decreasing strain rate and grain growth during testing complicate the normal analysis. Based on this study the requirements for superplastic behavior are a fine-grained microstructure, grain boundaries which are relatively free of obstructions and a homolohous temperature of at least 0.42. A model incorporating grain boundary shear and non-continuous grain growth has been proposed to account for the observed superplastic behavior where grain boundary migration is the rate controlling process.

description: Clouds interact with atmospheric radiation and substantially modify the Earth's energy budget. Cloud formation processes occur over a vast range of spatial and temporal scales, which make their thorough numerical representation challenging. Therefore, the impact of parameter choices for simulations of cloud-radiative effects is assessed in the current study. Numerical experiments are carried out using the ICOsahedral Nonhydrostatic (ICON) model with varying grid spacings between 2.5 and 80 km and with different subgrid-scale parameterization approaches. Simulations are performed over the North Atlantic with either one-moment or two-moment microphysics and with convection being parameterized or explicitly resolved by grid-scale dynamics. Simulated cloud-radiative effects are compared to products derived from Meteosat measurements. Furthermore, a sophisticated cloud classification algorithm is applied to understand the differences and dependencies of simulated and observed cloud-radiative effects. The cloud classification algorithm developed for the satellite observations is also applied to the simulation output based on synthetic infrared brightness temperatures, a novel approach that is not impacted by changing insolation and guarantees a consistent and fair comparison. It is found that flux biases originate equally from clear-sky and cloudy parts of the radiation field. Simulated cloud amounts and cloud-radiative effects are dominated by marine, shallow clouds, and their behavior is highly resolution dependent. Bias compensation between shortwave and longwave flux biases, seen in the coarser simulations, is significantly diminished for higher resolutions. Based on the analysis results, it is argued that cloud-microphysical and cloud-radiative properties have to be adjusted to further improve agreement with observed cloud-radiative effects. © 2020.

The geology and mineral deposits of the Moina-Lorinna area
Creators: name: Gee, CE
Publisher: name: University Of Tasmania
Year: 2023

description: The oldest rocks exposed in the area are quartzites and schists of the Dove Group which underwent considerable deformation during the Precambrian. Upper (?) Cambrian acid lavas, volcanics, greywackes, cherts, siltstones and quartzites comprise the Bull Creek Volcanics and the Lorinna Volcanics. These rocks were formed in an easterly extension of the Dundas Trough, north of the Tyennan Block. The Dove Granodiorite intruded these rocks along the southern margin of the Trough in Late Jukesian (?) times. The petrology of the Cambrian rocks is discussed in some detail and it is concluded that the acid lavas were derived from the same magma as the Dove Granodiorite. Ordovician rocks in this area consist of the Roland Conglomerate at the base, which is conformably overlain by the Moina Sandstone and the Gordon Limestone in turn. During the Tabberabberan Orogeny, these rocks were folded and faulted into northwesterly trending structures. The Dolcoath Granite intruded late in the Tabberabberan Orogeny causing some metamorphism of the country rocks. It is suggested the granite intruded as a northerly dipping, roughly tabular body. There may be a small cupola in the Stormont area. The majority of the mineral deposits in this area are genetically related to the Dolcoath Granite. A fairly distinct zone of wolframcassiterite deposits surrounds the northern part of the granite. Around this, is a zone of auriferous sulphides. The mineralogy of these two zones is described. Areas most likely to prove of economic importance are indicated together with suggested sites for a preliminary diamond-drilling programme.
Auto-Sizing Neural Networks: With Applications to n-gram Language Models

Year: 2023

description: Neural networks have been shown to improve performance across a range of natural-language tasks. However, designing and training them can be complicated. Frequently, researchers resort to repeated experimentation to pick optimal settings. In this paper, we address the issue of choosing the correct number of units in hidden layers. We introduce a method for automatically adjusting network size by pruning out hidden units through L∞,1 and L2,1 regularization. We apply this method to language modeling and demonstrate its ability to correctly choose the number of hidden units while maintaining perplexity. We also include these models in a machine translation decoder and show that these smaller neural models maintain the significant improvements of their unpruned versions.
Structure and petrology of the Raglan Range
Creators: name: Gee, Dennis
Publisher: name: University Of Tasmania
Year: 2023

description: Raglan Range consists dominantly of pelitic schists, quartzites, and ortho-amphibolites generally of garnet grade. This is the Franklin Group, and overlies Mary Group phyllites of chlorite grade. All are Precambrian. Precambrian structures show a regional and systematic departure from homoaxiality due to a rotation 'about an axis trending 326 degrees (true), and plunging 24 degrees This is the expression of Tabberabberan folding. Unrolling about this axis reveals a uniformly gently dipping alternation of schist and quartzite over most of the area. Two Precambrian deformations are recognisable, here termed SI and S2. Associated with SI is the regional metamorphism producing chlorite, biotite, a amandine , kyanite in a zonal arrangement. The biotite isograd is taken as the upper limit of the Mary Group. S2 is accompanied by retrograde metamorphism and large scale recumbent folding, during which metamorphic zones were inverted, and the Franklin Group was transported over the Mary Group, possibly in a south-west direction. The Governor River Phyllite, herein defined, is a wide zone of dispersed movement associated with S2. Albite of metasomatic origin crystallised in the interval between SI and S2. Quartzites show R-tectonite micro-fabric. The quartz fabric is homogeneous, irrespective of tectonic position, hut the mica fabric is unrollable. Lineation in quartzite is due to the intersection of SI surfaces with an older surface, probably bedding. Lineation in schist is the intersection of the SI surfaces and axial surfaces related to the S2 folds. Approximately coaxial relationships between SI, S2 and the Tabberabberan folding permits a construction of a tectonic profile of the Raglan Range by axial projection. Lamprophyre dykes, probably Tabberabberan in age intrude the schists.
Dominant temperature-sensitive lethal and semilethal mutations on chromosome 2 of Drosophila melanogaster.
Creators: name: Procunier, James Douglas
Publisher: name: University of British Columbia
Year: 2011

description: Conditional lethal mutants which die under restrictive conditions but are viable in a permissive environment provide useful tools for the genetic and developmental analysis of certain loci. One class of conditional mutants, temperature-sensitive recessive lethals which die at 29°C but survive at 23°C has been reported for an extensive number of loci in Drosophila melanogaster. However, loci may exist which are highly redundant, or concerned with functions requiring the total output of both wild type alleles or with synthesis of a structural component which would pre-exempt their ready detection as recessive mutations. Mutations within such regions could, however, be recovered by selecting temperature-sensitive mutations which behave as dominant lethals at the restrictive temperature. In addition, such mutants would permit the first genetic characterizations of dominant lethals. Ethyl methanesulfonate-induced dominant temperature-sensitive lethal and semi lethal mutations were induced in chromosome 2. Twenty-one lethals of this type were isolated from 6,130 tested chromosomes and sixteen were characterized with respect to their genetic localization and developmental effects. Unexpectedly, eleven of the mutants were found to be closely linked to the dumpy, dp, locus. All eleven were recessive lethals at room temperature and were functionally allelic. The temperature-sensitive period (TSP) was similar for all cluster mutants although the effective lethal phase (LP) at 29°C differed. It was concluded that the cluster lethals are, in fact, genetically allelic. Three other loci were demonstrated by genetic recombination and each had a characteristic TSP and LP. In addition, two mutants caused sterility of females and could not be localized. The recovery of mutations which map genetically within a segment and are dominant lethals, proves that dominant lethality need not reflect gross chromosomal alterations in higher organisms.

It drains Lake St Clair in the southern central highlands, and meanders over 200km down to Storm Bay south of Hobart where it eventually joins the Tasman Sea. The modem river deposits most of its suspended sediment load between New Norfolk and Bridgewater, and an area of fluvio-deltaic mud flat is developed north of the Bridgewater causeway. South of the causeway is the Estuary proper, and this extends to the entrance of Storm Bay, marked by the significant widening of the water body just south of the Iron Pot. The length of the Estuary between Bridgewater and Storm Bay is nearly 60km, and it is up to 6km wide. The bulk of this study was conducted in the southern portion of the Estuary, between Hobart in the north and Betsey Island in the south, excluding Ralphs Bay to the east and North West Bay to the West. Some seismic data were collected further upstream, as far north as the Bowen Bridge. See the location maps for details. (Since the city of Hobart is built on the banks of the Estuary, access is excellent. There are major roads and numerous boat launching and mooring points along both shores of the river. The boats used for this study were launched near Electrona in North West Bay, at the Regatta Grounds near the Cenotaph and at the Derwent Sailing Squadron (DSS) in Sandy Bay. Access to the DSS ramp and mooring facilities was arranged by Dr. Michael Roach. The other launching points are freely accessible to the public, via good quality sealed roads.

description: Primordial magnetic fields and massive neutrinos can leave an interesting signal in the CMB temperature and polarization. We perform a systematic analysis of general perturbations in the radiation-dominated universe, accounting for any primordial magnetic field and including leading- order effects of the neutrino mass. We show that massive neutrinos qualitatively change the large- scale perturbations sourced by magnetic fields, but that the effect is much smaller than previously claimed. We calculate the CMB power spectra sourced by inhomogeneous primordial magnetic fields, from before and after neutrino decoupling, including scalar, vector and tensor modes, and consistently modelling the correlation between the density and anisotropic stress sources. In an appendix we present general series solutions for the possible regular primordial perturbations.

description: The impetus toward development of multinational common markets is a worldwide phenomenon, recently showing a renewed vigor in Latin America. The largest common market of Latin America is MERCOSUR/MERCOSUL formed by the Southern Cone countries of Argentina, Brazil, Paraguay, and Uruguay. A great deal has been written about this market, the majority of which discusses it in terms of its economic, political, and social ramifications. The following bibliography is intended to present a wide sampling of materials, highlighting those issues of greatest concern. Most titles describe the content of the publications, but when that is not the case, annotations are included. The majority of the publications are written in Spanish, with Portuguese (i.e., MERCOSUL) or English materials recognizable by their titles. Treatment of MERCOSUR/MERCOSUL as a capitalized or lower-case acronym in titles conforms to the style used in each publication. All materials cited are located in the Benson Collection stacks.
Immune system modulation in the brain injury of the metallothionein-I/II null mutant mouse

description: Metallothionein-I/II (MT-I/II) is a 6-7 kDa, cysteine rich, zinc and copper binding protein. MT-I/II null mutant (\\(^{‚Äöv†v¿/‚Äöv†v¿}\\)) mice have an altered response to brain injury. Therefore, MT-I/II has been proposed to be a protective protein after brain injury but the mechanism by which it confers protection remains elusive. There is a possibility that MT-I/II has protective actions within the injured brain but MT-I/II also has the capacity to modulate the immune system which plays a role in the progression of brain injury. The aim of this thesis is to investigate the differences in the progression of brain injury between wild type and MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice with particular emphasis on the action of MT-I/II in organs peripheral to the central nervous system after brain injury. Using a cryolesion brain injury model, neuron death in MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice was prolonged at later stages of the brain injury (7 days post-injury) meanwhile it had ceased in wild type mice. In conjunction with this occurrence, the numbers of T cells infiltrating the injury site were significantly higher in MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice at 7 days post-injury. Chemokine mRNA synthesis was analysed to determine if MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice had altered chemotactic signals that may affect the rate of T cell infiltration but differences were rarely observed when compared to wild type mice. In MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice, circulating leukocytes showed no differences to wild type mice in the relative ratios of lymphocytes, neutrophils, monocytes or T cells. However, the absolute white blood cell count was significantly higher in the blood of MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice, but only at 7 days post-injury. MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice were also found to have lower levels of the marker of alternatively activated macrophages, Ym1, than wild type mice, both in macrophages in the brain and in monocytes in the blood after brain injury. Therefore, there appear to be several immune system differences between MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice and wild type mice after brain injury. To further investigate the role of MT-I/II after brain injury, MT-I and MT-II mRNA levels were quantified by reverse transcriptase PCR. An enzyme-linked immunoassay (ELISA) was developed to measure MT-I/II protein levels in brain and liver after brain injury. Both MT-I and MT-II mRNA levels increase at 1 day post-injury in brain and liver and are decreased by 7 days post-injury. MT-I/II protein in brain was highest at 1 day post-injury but in the liver was maximally expressed at 7 days post injury. This increase in hepatic MT-I/II protein resulted in a higher hepatic zinc content in wild type mice compared to MT-I/II\\(^{‚Äöv†v¿/‚Äöv†v¿}\\) mice. Therefore these results suggest that brain injury induces a hepatic MT-I/II response which may be responsible for modulation of the essential trace metal, zinc after brain injury.
Examination of the Canada Land Capability Classification for forestry.

description: A description of the Canada Land Capability Classification for forestry, and an analysis of data collected in the East Kootenay and Vanderhoof Districts of British Columbia were presented. A brief description of the climate, geology, physiography and soils in the East Kootenays was given. A description of the objectives of the land capability for forestry and a survey of the pertinent literature was included. The determination of Forest Land Productivity, and the accuracy of assigned productivity classes, were reviewed. It was found that the sources of error in productivity determinations included: (1) insufficient plots, (2) problems in defining 'normal' stocking, (3) extrapolation of MAI to a base of 100 years, (4) a strong tendency to select plots on northern aspects, and (5) the exclusion of plots on soils not representative of soil series descriptions. Two alternative methods for assigning productivity classes were discussed. They were point sampling and regression techniques. Both the point sampling and regression techniques gave results comparable to the conventional method, i.e. MAI determinations based on 1/5th acre plots, within prescribed constraints, and only in the interior of British Columbia. Results obtained from point samples on Vancouver Island were significantly different from those obtained on one-twentieth acre plots. The assignment of productivity subclasses was discussed. Here the only method presently feasible is a value judgement made by research workers. The results of the study revealed three areas where further research would result in a more accurate Forest Land Classification. These areas include: (1) the measurement of environmental factors which determine forest productivity, (2) the use of field and greenhouse experiments to establish methods for determining the relative effect of environmental influences in limiting tree growth, and (3) a more extensive study of the use of various sampling techniques to get a direct measure of productivity in terms of MAI.

description: Monte Carlo (MC) simulations are used to compute the centrality dependence of the collision zone eccentricities ($ε_{2,4}$), for both spherical and deformed ground state nuclei, for different model scenarios. Sizable model dependent differences are observed. They indicate that measurements of the $2^{\text{nd}}$ and $4^{\text{th}}$ order Fourier flow coefficients $v_{2,4}$, expressed as the ratio $\frac{v_4}{(v_2)^2}$, can provide robust constraints for distinguishing between different theoretical models for the initial-state eccentricity. Such constraints could remove one of the largest impediments to a more precise determination of the specific viscosity from precision $v_{2,4}$ measurements at the Relativistic Heavy Ion Collider (RHIC).
