The Hobart taxi industry : an evaluation
Creators: name: Maclean, Charles
Publisher: name: University Of Tasmania
Year: 2023

description: This study investigates the regulation of the taxi industry in Hobart. The economic rationale behind the present control of the industry is questioned. The amendments to the Tasmanian Traffic Amendment (Public Vehicles) Act 1983 have provided a different brand of taxi industry regulation compared to those in other areas of Australia. The study reviews the factors which led to the 1983 Traffic Amendment Act reforms and concludes that on economic grounds further changes are justified. Chapter 1 outlines the programme of investigation. Chapter 2 presents a background on factors which have led to the existing system of regulation and identifies problems with the existing system. Chapter 3 considers whether regulation is required and the effects of controlling both fares and the number of taxis. Chapter 4 describes the existing tariff structure and proposes a peak load pricing solution for the demand conditions found in Hobart. Chapter 5 proposes new directions for the industry based on the findings of earlier chapters.

description: For translationally shape invariant potentials, the exact quantization rule proposed by Ma and Xu is a direct consequence of exactness of the modified WKB quantization condition proved by Barclay. We propose here a very direct alternative way to calculate the appropriate correction for the whole class of translationally shape invariant potentials.

description: Buscar dados na internet para diversos fins, tem se tornado uma prática muito comum em usuários com acesso à algum tipo de tecnologia, como computadores, smartphones e tablets. Há estudos mostrando que indivíduos buscam na internet dados sobre seus estados de saúde, sintomas e possíveis diagnósticos. Um dos tópicos bastante comum nas buscas dos usuários, é saúde mental (Bach & Wenz, 2020; Milinovich et al., 2014). Isso pode ser positivo de um certo aspecto, facilitando algumas inferências para indivíduos que não tem acesso fácil à serviços de saúde, mas também há um aspecto negativo de autodiagnósticos errôneos e precipitados, que dependeriam de análises clínicas e laboratoriais para maior precisão. Estes autodiagnósticos acabam por motivar a automedicação. (...)

description: H-alpha emission from neutral halo clouds probes the radiation and hydrodynamic conditions in the halo. Armed with such measurements, we can explore how radiation escapes from the Galactic plane and how infalling gas can survive a trip through the halo. The Wisconsin H-Alpha Mapper (WHAM) is one of the most sensitive instruments for detecting and mapping optical emission from the ISM. Here, we present recent results exploring the ionization of two infallling high-velocity complexes. First, we report on our progress mapping H-alpha emission covering the full extent of Complex A. Intensities are faint (<100 mR; EM <0.2 pc cm^-6 but correlate on the sky and in velocity with 21-cm emission. Second, we explore the ionized component of some Anti-Center Complex clouds studied by Peek et al. (2007) that show dynamic shaping from interaction with the Galactic halo.

description: The zero-point entropy of a spin glass is a difficult property to experimentally determine and interpret. Spin glass theory provides various predictions, including unphysical ones, for the value of the zero-point entropy, however experimental results have been lacking. We have investigated the magnetic properties and zero-point entropy of two spinel Cu2+ based spin glasses, CuGa2O4 and CuAl2O4. Dc- and ac-susceptibility and specific heat measurements show many characteristic spin glass features for both materials. The spin glass freezing temperature is determined to be Tf = 2.89 +/- 0.05 K for CuGa2O4 and Tf = 2.30 +/- 0.05 K for CuAl2O4. By integrating the specific heat data we have found that CuGa2O4 and CuAl2O4 have zero-point entropies of S0 = 4.96 JK-1mol-1 and S0 = 4.76 JK-1mol-1 respectively. These values are closest to the prediction for a Sherrington-Kirkpatrick XY spin glass, however they are notably higher than all of the theoretical predictions. This indicates that CuGa2O4 and CuAl2O4 have a greater degeneracy in their ground states than any of the spin glass models.

description: Four bare silica particle carriers with different particle sizes and functional organic-inorganic silica particles (SiO2-2/P4VP-psl) “grafted” by P4VP-psl (polypyridinium salt) were selected to test their antibacterial and antifouling activities. The relationships between particle sizes, grafting degrees of pyridinium salt unit and their antibacterial ability were investigated by using Escherichia coli (E. coli) ATTC25922 as model bacterium and calculated by the colony count method. The results showed that silica particle sizes did not work in its antibacterial and antifouling activities. Functional SiO2-2/P4VP-psl possessed both the good antibacterial, antifouling activities of zwitterionic polymers, and the stability advantage of inorganic particle, which was environmental friendly disinfection materials in purifying water. The antibacterial rate was almost 100%. The stability of SiO2-2/P4VP-psl in bovine serum albumin solutions was very excellent with the unchanged particle size for 60 h. Moreover, the higher the grafting degree of pyridinium salt unit was, the stronger the sterilizing ability of SiO2-2/P4VP-psl was.

description: Numa sociedade cada vez mais em “crise” de valores tem sido considerado necessário trabalhá-los desde os primeiros anos de escolaridade. Neste contexto surgiu a investigação desenvolvida na área de educação para os valores que foi implementada a alunos do 1º ano de escolaridade. Esta investigação assenta num paradigma socío-critico, de acordo com uma perspetiva metodológica qualitativa e com base num plano de investigação-ação e teve como principal finalidade a implementação de atividades de educação para os valores, adaptadas e utilizadas neste estudo, e a verificação dos seus contributos para uma melhoria das atitudes e valores, em contexto escolar, de alunos de uma escola região centro em 2017/18. Para isso, foram desenvolvidas 5 sessões de educação para os valores que permitiram recolher um conjunto alargado de dados. Depois de recolhidos procedeu-se à sua análise de conteúdo, recorrendo-se ao software webQDA (versão 3.0). Relativamente aos resultados, estes apontam para o nível 1 e 2 do raciocínio moral destas crianças, tendo como referência o trabalho de Kolhberg. No que se refere às “atitudes dos alunos” pareceu existir uma melhoria gradual ao longo das sessões As atividades implementadas indicam terem contribuído para uma melhoria das atitudes dos alunos. No entanto, a melhoria apresentada não se pode considerar substancial e para todos. O principal contributo deste estudo, ainda que modesto, prende-se com as potencialidades das atividades implementadas e da confirmação da sua utilidade para clarificar atitudes/valores de alunos deste nível etário e melhorar o seu nível de raciocínio moral.

description: Three MgCl2 supported TiCl4 pro-catalysts; Cat-A, Cat-B and Cat-C were synthesized. Cat-A was synthesized without any internal Lewis base (ILB); while Cat-B and Cat-C were synthesized using diisobutyl phthalate and ethyl benzoate as ILBs respectively. The effect of ILBs on stereoregularity and the microstructure of polybutadiene (PBD) was investigated. The vast differences in the amount of trans-1,4-structure of PBD by Cat-A, Cat-B and Cat-C systems were correlated with the nature of ILBs used by studying their polymerization kinetics. The energy barriers for polymerization reactions were calculated for all three catalysts systems using Arrhenius equation. Cat-B, has shown the highest energy barrier (23 kJ/mol) due to DIBP as ILB in its structure. Cat-A has given the lowest trans-1,4-PBD as it does not contain any ILB and has the minimum energy barrier (12 kJ/mol) while Cat-C has shown medium energy barrier (17 kJ/mol). We have also studied the effect of suitable external Lewis bases during polymerization. The effect of polymerization parameters like Al/Ti molar ratio, Al/LB molar ratios and the temperatures on PBD microstructure were studied. Based on the polymerization kinetics studies and the effect of LBs on PBD microstructure, a possible reaction mechanism has been proposed.
Finite-Size Scaling for Quantum Criticality above the Upper Critical Dimension: Superfluid-Mott-Insulator Transition in Three Dimensions

description: Validity of modified finite-size scaling above the upper critical dimension is demonstrated for the quantum phase transition whose dynamical critical exponent is $z=2$. We consider the $N$-component Bose-Hubbard model, which is exactly solvable and exhibits mean-field type critical phenomena in the large-$N$ limit. The modified finite-size scaling holds exactly in that limit. However, the usual procedure, taking the large system-size limit with fixed temperature, does not lead to the expected (and correct) mean-field critical behavior due to the limited range of applicability of the finite-size scaling form. By quantum Monte Carlo simulation, it is shown that the same holds in the case of N=1.

description: Characteristics of a Hamilton-Jacobi equation can be seen as action minimizing trajectories of fluid particles. For nonsmooth "viscosity" solutions, which give rise to discontinuous velocity fields, this description is usually pursued only up to the moment when trajectories hit a shock and cease to minimize the Lagrangian action. In this paper we show that for any convex Hamiltonian there exists a uniquely defined canonical global nonsmooth coalescing flow that extends particle trajectories and determines dynamics inside the shocks. We also provide a variational description of the corresponding effective velocity field inside shocks, and discuss relation to the "dissipative anomaly" in the limit of vanishing viscosity.

description: Günter Görlichs Buch Den Wolken ein Stück näher wurde in der DDR breit rezipiert, nicht nur unter Jugendlichen. Zudem war es einer der wenigen zeitgenössischen Jugendromane, die – wenn auch erst anderthalb Dekaden nach Erscheinen – Eingang in den Unterrichtskanon des Landes fanden. Dieses Nebeneinander einer breiten öffentlichen (vergleichsweise weniger gelenkten) Rezeption und der Thematisierung im Literaturunterricht macht sich der hier vorgelegte Beitrag zunutze, um die Beschäftigungen mit dem Roman in den Pädagogischen Lesungen innerhalb der Gesamtrezeption und innerhalb der verschiedenen Unterrichtsvorgaben und -empfehlungen zum Roman zu verorten. Berücksichtigt werden dabei Verlagsgutachten und Presserezensionen als Dokumentationen der außerschulischen Wahrnehmung, Artikel in der Zeitschrift Deutschunterricht sowie die Ausführungen zum Thema in der Unterrichtshilfe für den Literaturunterricht und die Pädagogischen Lesungen selbst. In der Summe zeichnet die Betrachtung der hier konsultierten Quellen eine Rezeptionschronologie, in der die Pädagogischen Lesungen sich als letzte zu Wort melden. Der Vergleich der verschiedenen Rezeptionspfade zeigt, dass man, als man dies dann tut, keine Alternativen zu bestehenden Unterrichtsvorgaben entwickelt. Vielmehr modifiziert man die Vorgaben der Unterrichtshilfen insofern, als man methodische oder mediale Umgestaltungen oder Abwandlungen vornimmt. Damit ist das Format in diesem Fall tatsächlich in der Lage, bislang an keinem anderen Ort behandelte und damit innovative Unterrichtspraxis zu präsentieren.

description: Stimuli-responsive polymers as drug delivery vehicles have generated remarkable interest among polymer researchers during the last decade. In the present work, we report the synthesis of a new water soluble pH- and thermo-responsive biocompatible block copolymer containing phenylalanine derivatives. The block copolymer formed micelle-like self-assembled nanoparticles above critical aggregation concentration, as confirmed from fluorescence spectroscopy, DLS, and AFM studies. The self-assembly behavior was dependent on the pH and temperature of the aqueous media. These self-assembled micellar nanoparticles were capable of encapsulating hydrophobic drugs as demonstrated by the significantly higher loading capacity value of Doxorubicin (DOX) compared to commonly reported values in the literature. The release of DOX from the nanoparticles was favored at lower pH and higher temperature, a condition prevalent in cancer cells. Biocompatibility of the block copolymer and the effectiveness of the nanoparticles in potential cancer therapy were established by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) studies using non-cancerous murine fibroblasts L929 cells and breast cancer cell line MDA MB 231 at 37 °C and 42 °C. The cytotoxicity of DOX loaded polymer nanoparticles was found to be more effective at 42 °C compared to 37 °C. Thus, these micellar nanoparticles hold promise in drug delivery application in cancer therapy.

Magnetic stress analysis of structural steel
Creators: name: Langman, RA
Publisher: name: University Of Tasmania
Year: 2023

description: The original aim of this project (on which the thesis is based) was to design an instrument that would measure stress in steel nondestructively by means of magnetic measurements, using the known fact that the magnetic properties of most steels are significantly affected by stress. It soon became apparent that there was a paucity of relevant magnetic theory, and so the project was widened to include a (mostly experimental) study of the effect of stress on the magnetisation curves of mild steel. These were measured for magnetisation parallel and perpendicular to the stress and for tensile and compressive stresses. The highest sensitivity to stress occurs on the steepest part of the magnetisation curve, which is where the stressinstrument is used, and is also where the theory is least satisfactory. Thus another aim is to relate magnetisation measurements and theory at moderate field strengths. The thesis is in three parts: I A review of experimental magnetic stress analysis, for the period 1950- 1980; work by about 12 individuals or groups is included. II An account of the author's experimental results, both for the development of the instrument to measure stress (called the Rotation Rig) and also for the more basic measurements of magnetic properties of steel under stress. Some work is also included on the effect of plastic strain and on the relation between Barkhausen noise and the rotation rig results. III A review of magnetomechanical theory, including a contribution from the author; theories or concepts that have some relevance are by Brown, Goodenough, Ginsburg, Watson, and Jiles and Atherton. The first aim, that of designing an instrument to measure stress, has been achieved. Strictly, only the differences in principal stresses, and their directions, can be measured. The results are analagous to photoelastic modeling but working on the actual steel instead of a plastic model. The rotation rig is cheap, quick, and convenient to use, and has an error of about lOMPa in optimum conditions. iii The . second aim, that of producing a theory to explain quantitatively the effect of stress on magnetisation at moderate magnetic fields, has not been achieved. In fact the complexity of the magnetic behaviour of steel makes any theory likely to be rather complicated. However, the symmetry of the experimental results on mild steel are explained theoretically by the author. Many of the measurements, especially those with biaxial stresses, have not been made before, and are a framework on which to base further theory.
A phenomenological equation of state for isospin asymmetric nuclear matter
Creators: name: Chen, Lie-Wen

Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)

description: A phenomenological momentum-independent (MID) model is constructed to describe the equation of state (EOS) for isospin asymmetric nuclear matter, especially the density dependence of the nuclear symmetry energy $E_{\text{\textrm{sym}}}(ρ)$. This model can reasonably describe the general properties of the EOS for symmetric nuclear matter and the symmetry energy predicted by both the sophisticated isospin and momentum dependent MDI model and the Skyrme-Hartree-Fock approach. We find that there exists a nicely linear correlation between $K_{\mathrm{sym}}$ and $L$ as well as between $J_{0}/K_{0} $ and $K_{0}$, where $L$ and $K_{\mathrm{sym}}$ represent, respectively, the slope and curvature parameters of the symmetry energy at the normal nuclear density $ρ_{0}$ while $K_{0}$ and $J_{0}$ are, respectively, the incompressibility and the third-order derivative parameter of symmetric nuclear matter at $ρ_{0}$. These correlations together with the empirical constraints on $K_{0}$, $L$ and $E_{\text{\textrm{sym}}}(ρ_{0}) $ lead to an estimation of -477 MeV $\leq K_{\mathrm{sat,2}}\leq -241 $ MeV for the second-order isospin asymmetry expansion coefficient for the incompressibility of asymmetric nuclear matter at the saturation point.

description: We study the variability of the nova-like cataclysmic variable TT Ari, on time-scales of between minutes and months. The observations in the filter R were obtained at the 40-cm telescope of the Chungbuk National University (Korea). TT Ari was in the "negative superhump" state after its return from the "positive superhump" state, which lasted 8 years. The ephemeris for 12 best pronounced minima is $T_{min}=BJD 2453747.0700(47)+0.132322(53)E.$ where numbers in digits are errors in units of the last digit. The phases of minima may reach 0.2, indicating non-eclipse nature of these minima. The quasi-periodic oscillations (QPO) are present with a mean "period" of 21.6 min and mean semi-amplitude of 36 mmag. This value is consistent with the range 15-25 minutes reported for previous "negative superhump" states and does not support the hypothesis of secular decrease of the QPO period. Either the period, or the semi-amplitude show significant night-to-night variations. According to the position at the two-parameter diagrams, the interval of observations was splitted into 5 parts, showing different characteristics which are discussed in this paper. The system is an excellent laboratory to study processes resulting in variations at time-scales from seconds to decades and needs further monitoring at various states of activity.

description: We present the results of a parsec-scale polarization study of three FRI radio galaxies - 3C66B, 3C78 and 3C264 - obtained with the Very Long Baseline Array at 5, 8 and 15 GHz. Parsec-scale polarization has been detected in a large number of beamed radio-loud active galactic nuclei, but in only a handful of the relatively unbeamed radio galaxies. We report here the detection of parsec-scale polarization at one or more frequencies in all three FRI galaxies studied. We detect Faraday rotation measures of the order of a few hundred rad/m^2 in the nuclear jet regions of 3C78 and 3C264. In 3C66B polarization was detected at 8 GHz only. A transverse rotation measure gradient is observed across the jet of 3C78. The inner-jet magnetic field, corrected for Faraday rotation, is found to be aligned along the jet in both 3C78 and 3C264, although the field becomes orthogonal further from the core in 3C78. The RM values in 3C78 and 3C264 are similar to those previously observed in nearby radio galaxies. The transverse RM gradient in 3C78, the increase in the degree of polarization at the jet edge, the large rotation in the polarization angles due to Faraday rotation and the low depolarization between frequencies, suggests that a layer surrounding the jet with a sufficient number of thermal electrons and threaded by a toroidal or helical magnetic field is a good candidate for the Faraday rotating medium. This suggestion is tentatively supported by Hubble Space Telescope optical polarimetry but needs to be examined in a greater number of sources.

description: We report a transit timing study of the transiting exoplanetary system HD 189733. In total we observed ten transits in 2006 and 2008 with the 2.6-m Nordic Optical Telescope, and two transits in 2007 with the 4.2-m William Herschel Telescope. We used Markov-Chain Monte Carlo simulations to derive the system parameters and their uncertainties, and our results are in a good agreement with previously published values. We performed two independent analyses of transit timing residuals to place upper mass limits on putative perturbing planets. The results show no evidence for the presence of planets down to 1 Earth mass near the 1:2 and 2:1 resonance orbits, and planets down to 2.2 Earth masses near the 3:5 and 5:3 resonance orbits with HD 189733b. These are the strongest limits to date on the presence of other planets in this system.

description: We derive the equations of motion for a planar rigid body of circular shape moving in a 2D perfect fluid with point vortices using symplectic reduction by stages. After formulating the theory as a mechanical system on a configuration space which is the product of a space of embeddings and the special Euclidian group in two dimensions, we divide out by the particle relabelling symmetry and then by the residual rotational and translational symmetry. The result of the first stage reduction is that the system is described by a non-standard magnetic symplectic form encoding the effects of the fluid, while at the second stage, a careful analysis of the momentum map shows the existence of two equivalent Poisson structures for this problem. For the solid-fluid system, we hence recover the ad hoc Poisson structures calculated by Shashikanth, Marsden, Burdick and Kelly on the one hand, and Borisov, Mamaev, and Ramodanov on the other hand. As a side result, we obtain a convenient expression for the symplectic leaves of the reduced system and we shed further light on the interplay between curvatures and cocycles in the description of the dynamics.

description: Various operative procedures have been described for urogenital tuberculosis (UGTB). These include percutaneous drainage of hydronephrosis or abscesses, double-J stenting for hydronephrosis, definitive local extirpative treatment of the affected part of a kidney (cavernotomy/partial nephrectomy) and epididymis (epididymectomy). Many forms of reconstructive surgery of the upper urinary tract (uretero-calycostomy, ureteric reimplantation, ileal ureteric replacement) and the lower urinary tract have been described. Nephrectomy is performed in 27% of UGTB patients and the frequency is similar in developing and developed countries. Radical and reconstructive procedures should be done within the first two months of intensive chemotherapy. A contracted bladder may need augmentation cystoplasty or even cystectomy if the capacity is less than 100 ml.

description: A multi-period inventory management model for perishable products is developed with simulation approach. A single-product scenario is modelled under continuous and periodic review policies, considering Weibull demand, non-null deterministic lead time, a combination of lost sales and backorders, fixed product shelf life, and service constraints. Eight inputs, including managerial aspects and product characteristics, and six outputs, i.e. the minimum cost and the optimal operating leverages of the two policies, are evaluated using Design of Experiments. Discrete-time simulation is used to determine, for each configuration, the optimal operating leverages, namely target stock level, reorder period, and base stock, which minimise the total cost under service constraints. The outcomes were then analyzed through Analysis of Variance and Response Surface Methodology, to assess the impact of each input parameter on the responses. Results show that the optimal operating leverages mainly depend on demand features, some unitary costs (order issuing in particular), shelf life, and lost sales fraction. The shelf life turns out to be significant only if lower than a threshold value, which varies with the shape factor of the demand distribution: for shelf life values greater than the threshold, the products could be managed as non-perishable from an inventory point of view.

description: The completion $\overline{A}[τ]$ of a locally convex *-algebra $A [ τ]$ with not jointly continuous multiplication is a *-vector space with partial multiplication $xy$ defined only for $x$ or $y \in A_{0}$, and it is called a topological quasi *-algebra. In this paper two classes of topological quasi *-algebras called strict CQ$^*$-algebras and HCQ$^*$-algebras are studied. Roughly speaking, a strict CQ$^*$-algebra (resp. HCQ$^*$-algebra) is a Banach (resp. Hilbert) quasi *-algebra containing a C$^*$-algebra endowed with another involution $\sharp$ and C$^*$-norm $\| \|_{\sharp}$. HCQ$^*$-algebras are closely related to left Hilbert algebras. We shall show that a Hilbert space is a HCQ$^*$-algebra if and only if it contains a left Hilbert algebra with unit as a dense subspace. Further, we shall give a necessary and sufficient condition under which a strict CQ$^*$-algebra is embedded in a HCQ$^*$-algebra.

description: This paper examines relationship of unemployment rates with other macroeconomic aggregates in Bangladesh over 1991-2019 using robust econometric analyses. It sheds a
light on the fact that GDP growth rate, inflation, and foreign direct investment flows have statistically significant impacts on unemployment rate both in short-run and long-run.
More specifically, the paper documents that unemployment rate, GDP growth rate, inflation rate and foreign direct investment flows are co-integrated in long-run at 5%
significance level. Using Vector Error Correction analysis, the paper finds that co-integrated series converge it
their long-run equilbruim at a speed of 17.24% per annum at 1% significance level. In case
short-run, the study finds that a unit increase in GDP growth rate decreases unemployment
by approximately 0.0159 units in short-run at 1% statistically significance level. Likewise, a
unit increase in inflation rate will lead approximately 0.004 units drop in unemployment
rate at 10% significance level. Plus, it also observes that a unit in Foreign Direct Investment
flows causes 0.005 units decrease in unemployment rate in short-run at 5% significance
level.
Gamma-Ray Burst Groups Observed by Different Satellites

description: Two classes of gamma-ray bursts have been identified in the BATSE catalogs characterized by durations shorter and longer than about 2 seconds. There are, however, some indications for the existence of a third one. Swift satellite detectors have different spectral sensitivity than pre-Swift ones for gamma-ray bursts. Therefore it is worth to reanalyze the durations and their distribution and also the classification of GRBs. In this paper we are going to analyze the bursts' duration distribution and also the duration-hardness bivariate distribution, published in The First BAT Catalog, whether it contains two, three or maybe more groups. Similarly to the BATSE data, to explain the BAT GRBs duration distribution three components are needed. Although, the relative frequencies of the groups are different than they were in the BATSE GRB sample, the difference in the instrument spectral sensitivities can explain this bias in a natural way. This means theoretical models may have to explain three different type of gamma-ray bursts.

Physiology of growth in apple fruits : between site variation in cell physiology and disorder incidence
Creators: name: Lewis, TL
Publisher: name: University Of Tasmania
Year: 2023

description: In recent years studies have been made of the variation in the physiology and disorder incidence of apples within a tree and between trees in one orchard, within a season and between seasons. One of the remaining problems is that of between-site variation. The existence of between-site variation is traditional, and is regarded by orchardists as considerable even when cultural treatments do not differ. For example, the fruit of the Braeside area in Southern Tasmania grown at an altitude of about 700 feet is reputed to be of superior keeping quality to that grown at the general level of the Huon Valley. Certain patterns of between-tree variation have now been established (Martin and Lewis 1952, Martin 1954a,b) which enable us to take account of some variables when making a between-site comparison. This thesis describes an attempt at such a comparison. It embodies investigations carried out in the period 1954-1956, using small plots on different sites in three localities in the Huon district of Tasmania, with a view to finding answers to the following questions: (1) Do differences between sites depart significantly from the normal between-tree variation? (2) Does fruit from high and low altitudes differ in its susceptibility to disorders? (3) If there are any site or altitude differences in disorder susceptibility are they accompanied by significant differences in the physiological characteristics of the fruit? If so, do these differences tend to confirm or deny theories developed from the between-tree studies? (4) Are there any differences in the between-site variation between seasons, and if so how far are they in line with indications from the ideas developed from other studies?

description: Let $N=L_n(q)$, {$n \geq 2$}, $q$ a prime power, be a projective linear simple group. We classify all Steiner quadruple systems admitting a group $G$ with $N \leq G \leq \Aut(N)$. In particular, we show that $G$ cannot act as a group of automorphisms on any Steiner quadruple system for $n>2$.
