Angular-momentum coupling through the tachocline
Creators: name: Gough, D. O.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Astronomical observation of stellar rotation suggests that at least the surface layers of the Sun have lost a substantial amount of the angular momentum that they possessed at the beginning of the main-sequence phase of evolution; and solar-wind observations indicate that magnetic coupling is still draining angular momentum from the Sun today. In addition, helioseismological analysis has shown that the specific angular momentum at the top of the almost uniformly rotating radiative interior is approximately (although not exactly) the same as the spherically averaged value at the base of the (differentially rotating) convection zone, suggesting that angular momentum is being transported through the tachocline. The mechanism by which that transport is taking place is not understood. Nor is there a consensus of opinion. I review some of the suggestions that have been put forward, biassing my discussion, no doubt, according to my own opinions.

title: The riddle of history: Marx's concept of socialism in the context of his epistemology and theory of history
Creators: name: Kelly, Ray
Publisher: name: University of Kent
Year: 2021

description: Within the organisation of all societies, there are basic contradictions which historically have given rise to certain undesirable structural features. These same contradictions also lie at the root of alienated, ideological forms of consciousness which act as a barrier to the solution of these problems. In chapter one, I will deal with each of these issues in turn, thus introducing Marx's problematic, i. e. the so-called "riddle of history". Chapters two and three contain a discussion of Marx's methodology, which was intended to avoid the pitfalls of ideological forms of consciousness and provide a theoretical framework for coming to terms with the problem. Chapter three in particular provides a syntax and a logical explanation for the terms and forms of argument employed in the rest of the thesis. Marx believes that historical development itself determines the possibility of solving the problems referred to. Chapters four and five, therefore, are an analysis of the processes which govern the development of social structures, i. e. so-called "Historical Materialism". Chapter six is an investigation of the relationship between historical change and forms of consciousness. This sets the stage for an analysis in chapter seven of the nature of capitalism itself and how it gives rise in the consciousness of the working class to a solution, in principle, to the problems identified in chapter one. Finally, chapter eight reviews the factors within the development of capitalism which might make possible the transition to socialism and the implementation of the solution in practice.

description: We have constructed an optical clock with a fractional frequency inaccuracy of 8.6e-18, based on quantum logic spectroscopy of an Al+ ion. A simultaneously trapped Mg+ ion serves to sympathetically laser-cool the Al+ ion and detect its quantum state. The frequency of the 1S0->3P0 clock transition is compared to that of a previously constructed Al+ optical clock with a statistical measurement uncertainty of 7.0e-18. The two clocks exhibit a relative stability of 2.8e-15/ sqrt(tau), and a fractional frequency difference of -1.8e-17, consistent with the accuracy limit of the older clock.

Modelling the foraging ecology of the flesh-footed shearwater Puffinus carneipes in relation to fisheries and oceanography
Creators: name: Reid, TA
Publisher: name: University Of Tasmania
Year: 2023

description: Increasing numbers of animal and plant species are under threat, often through human activity. To improve management of these species, it is important to understand the spatio-temporal nature of these interactions. In this thesis the threats to flesh-footed shearwater breeding on Lord Howe Island were explored, and methods that can be adopted for lowering them were investigated. A census of the population of flesh-footed shearwaters on Lord Howe Island indicated a continuing decline. Possible threats to the population that were identified as (i) offshore, in the form of fisheries by-catch and plastic pollution at sea, and (ii) onshore, with factors such as land clearance and road mortality on Lord Howe Island. Significant mortality was recorded on roads on Lord Howe Island. Offshore threats were examined by quantifying the regions of interactions between flesh-footed shearwaters and vessels operating in the Eastern Tuna and Billfish Fishery using data from fisheries observers, Australian Fisheries Management Authority logbook data and remote sensing data of oceanographic variables. Recent changes in the regions of interaction between the shearwaters and the ETBF were modelled, and how this affected the by-catch rate was examined. The effect these changes had on the by-catch rate was used to recommend the potential of area closures as a method of conservation. Using a novel statistical technique, the distribution of flesh-footed shearwaters and their interactions with the ETBF was further examined. Small scale oceanographic relationships between the shearwaters‚ÄövÑvº attendance of vessels operating in the fishery were quantified using an arrivals and departures multi-component model. For this the same data as that used in the previous section was used. By comparing the arrivals and departures for shearwaters behind vessels, finer scale attendance was examined and compared with the hypothesis that shearwaters were more likely to attend a vessel when it was operating in conditions that were likely to be more productive. Finally, the distribution of individual flesh-footed shearwaters during the breeding season was quantified using light based archival tags (GLS loggers). Discrete Choice Models were then used to examine if individuals returned to the same areas on successive trips. Flesh-footed shearwaters used experience to determine where they were foraging, returning to areas that they had visited during the previous two foraging trips, and returning to areas where they apparently were successful during those trips. This has rarely been demonstrated previously, especially for larger or oceanic animals.
Coherent local oscillators for a 21 cm. supersynthesis experiment
Creators: name: Shimozawa, David Tetsuo
Publisher: name: University of British Columbia
Year: 2011

description: A method based on phaselock techniques, for synchronizing the local oscillator signals in a proposed two-dish supersynthesis at 1420 MHz is presented. To demonstrate the feasibility of this method, the design and construction of a working system that provides phase-coherent, 1390 MHz signals at two sites, separated by a time-varying path length, is described. The phase accuracy of this system is ±5°. A provision for introducing a known phase difference between the two signals, in a manner that is suitable for interfacing with a digital computer, is included. Also, operation of the system over a frequency range greater than the expected range of doppler shift is possible, without the risk of locking to a wrong sideband. Transistor microwave oscillators at 1.4 GHz are used as voltage-controlled oscillators in this system. The performance of these devices is compared with that of the conventional voltage-controlled crystal oscillator/multiplier chain. Test results are given, which indicate that the system is suitable for use in an operational environment.

We study the conditions for asymptotic freedom and give a practical method to determine the asymptotic-freedom domain. We also point out that in some models the RG flow contains "rational" Zimmermann trajectories that might hide new symmetries.

description: We present a new approach for studying the chemodynamical evolution of the Milky Way, which combines a thin disk chemical evolution model with the dynamics from N-body simulation of a galaxy with properties similar to those of our Galaxy. A cosmological re-simulation is used as a surrogate in order to extract ∼11 Gyrs of self-consistent dynamical evolution. We are then in a position to quantify the impact of radial migration at the Solar Vicinity. We find that the distribution of birth radii, r0, of stars ending up in a solar neighborhood-like location after ∼11 Gyr of evolution peaks around r0 = 6 kpc due to radial migration. A wide range of birth radii is seen for different age groups. The strongest effect from radial migration is found for the oldest stars and it is connected to an early merger phase typical from cosmological simulations. We find that while the low-end in our simulated solar vicinity metallicity distribution is composed by stars with a wide range of birth radii, the tail at larger metallicities (0.25
Changing ethics - changing perceptions
Creators: name: Doyle, Z
Publisher: name: University Of Tasmania
Year: 2023

description: The concept of ethics is something that all researchers must come to terms with every time they consider a study involving humans or animals. Since the Nuremberg Trials, the changing needs of the research community with regards to research design and the recruitment of participants has seen requirements for participation in studies change dramatically with respect to ethical guidelines. The aim of this thesis is to investigate, through well-documented long-term public health cohort studies, how changing perceptions of ethics have impacted on research design and outcomes. The research has been undertaken particularly from an epidemiological point of view as well as in terms of rates of participation. In order to explore the evolution of ethical thinking and its potential effect on long-term longitudinal cohort studies with a public health bias, an iterative search process was employed to determine eligible studies and to extract relevant papers for the literature review. Examination of response rates in the context of the recruitment processes and ethical constructs in place at the time of recruitment was also undertaken. In addition to qualifying the nature of change in the ethical landscape, it is important to note that questions and changes resulting from ethics frameworks and committees may affect both the implementation and interpretation of the proposed work. By establishing this framework of change, the thesis explores and examines the impact of what can be coined as the ‚ÄövÑvØNew Ethics Research Environment‚ÄövÑv±. A retrospective examination of landmark studies with respect to how they may be affected by contemporary guidelines was used to illustrate the influence of the New Ethics Research Environment on large scale cohort studies which impact on health research outcomes at both an international and local level. The significance of this thesis is that it highlights the fact that ethics, as a construct in long-term research, generally has the most impact during recruitment and initial implementation of the study. Ethics, as an evolving concept, does not appear to affect long term studies which do not, themselves, change in scope ‚Äö- that is, those studies with only one cohort and no change in methodology. However, when cohorts are continually recruited, changing ethics and changing perceptions have significantly impacted on cohort selection and methodology both prospectively and retrospectively.
Numerische Untersuchung von mechanischen und thermischen Eigenschaften von Gusseisen mit Lamellengraphit

description: Gusseisen ist ein Werkstoff, der seit langem und in großem Umfang eingesetzt wird. In Deutschland liegt sein jährliches Produktionsvolumen bei mehreren Millionen Tonnen. Das Mikrogefüge von Gusseisen besteht aus einer metallischen Matrix mit Graphiteinschlüssen. In dieser Arbeit wird Gusseisen mit Lamellengraphit untersucht. Gusseisen mit Lamellengraphit wird in sehr sicherheitskritischen Bereichen wie beispielsweise Bremsscheiben oder thermo-mechanisch hochbelasteten Anwendungen wie Zylinderköpfen eingesetzt. Seine makroskopischen Werkstoffeigenschaften sind stark von der vorhandenen Mikrostruktur abhängig. Der quantitative Zusammenhang zwischen den Werkstoffeigenschaften und dem Gefüge ist oft nicht bekannt. Um in Zukunft bessere numerische Vorhersagen zu ermöglichen, werden makroskopische mikrostrukturbasierte thermische und mechanische Materialeigenschaften für einen großen Temperaturbereich berechnet. Die spezifischen mechanischen Eigenschaften von Gusseisen mit Lamellengraphit in Zug und Druck werden berücksichtigt. Die notwendigen Simulationsgebiete werden algorithmisch auf Basis von Wahrscheinlichkeitsverteilungen nach DIN EN ISO 945-1 generiert. Weiterführend wird ein Phasenfeldrissmodell eingeführt, das die Simulation von Rissentstehung und -ausbreitung in Verbundwerkstoffen mit spröd-anisotropen und duktilen Komponenten in Anlehnung an Gusseisen mit Lamellengraphit ermöglicht. Als Vorarbeit für das Rissmodell wird ein Homogenisierungsansatz für den Mehrphasenfeldkontext eingeführt, der es erlaubt, die elastoplastischen Verzerrungen in mehrphasigen Übergangsbereichen, unter Beachtung der mechanischen Sprungbedingungen, zu berechnen. Ein solches Modell ist für Gusseisen wichtig, um das Auftreten von plastischen Verformungen in Graphitpartikeln zu vermeiden.
Socio-political issues in women's fiction of the Reformasi
Creators: name: Eagling, CM
Publisher: name: University Of Tasmania
Year: 2023

description: Long struggling for a platform for woman's voice, Indonesian women authors have been publishing novels and anthologies of stories, poetry and articles in unprecedented numbers since the beginning of Reformasi. Not unnoticed has been their common use of sex and sexuality as a prominent component of their writings. Many of the authors have been labelled with the term sastrawangi; a friendly but patronizing and slightly derogatory label. The following critique illuminates the more important but previously un-investigated facets of literature from this generation of authors and brings to light the works of some authors that, due to the authors avoidance of sex and sexuality, have been overlooked as subjects of criticism. Through close readings of writers including Ayu Utami, Helvy Tiana Rosa, Linda Christanty and Laksmi Pamuntjak, this critique exposes socio-political aspects and motivations in modern Indonesian literature written by women authors. The readings were undertaken using a cultural materialist framework, drawing out the socio-political issues identified within the stories. The stories of chapter two contain clear references to actual events in recent Indonesian history. They reveal authorial commitment to the exposition of social and political issues such as war, conflict and religious or ethnic tension. Chapter three analyses the socio-political effects of globalisation, westernisation and the inherent difficulties of early democracy in the anthology of short stories by Laksmi Pamuntjak The Diary of R.S.: Musings on Art. The analysis indicates that women writers of the Reformasi era are showing a commitment to articulating the socio-political tensions of their era and exhibiting a certain social struggle with the newfound ‚ÄövÑvªfreedoms‚ÄövÑvº of post-Suharto Indonesia.

description: In an increasingly saturated global market, winegrowers and wineries have an opportunity for product differentiation born out of environmental and social pressures coupled with growing consumer preferences. The wine industry has seen significant establishment of sustainable certification systems as wine consumers preferences for sustainability have developed. However, there is a risk that the prominent use of symbol and icon type labels may obscure individual sustainability attributes and weaken signalling to consumers searching for specific credentials. Consumers may respond to individual components of sustainability programs differently to others and the use of simplistic symbols and logos makes it difficult for consumers to identify which elements are contained within a scheme.

description: A model of inflation is presented where the inflaton field is a complex scalar field coupled to a U(1) gauge field. Due to the axial symmetry of the potential, the inflation is driven by the radial direction while the angular field is gauged by U(1). Due to the coupling of the inflaton to the gauge field, a time dependent mass term for the gauge field is generated dynamically and conformal invariance is broken. We study whether a significant amount of primordial magnetic fields can be generated during inflation by allowing a time-dependent U(1) gauge kinetic coupling.

The diary of Tamura Yoshikazu : writing under the gaze of the kokutai during the Japanese Imperial Army New Guinea campaign
Creators: name: Eaves-Young, VL
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this thesis is to investigate the influence of the social context of imperial Japan on the diary of Tamura Yoshikazu, a member of the Japanese Imperial Army stationed in New Guinea from January 1943 until his presumed death at the end of the same year. As one of the few remaining original diaries from the New Guinea theatre of the Pacific War, this material offers a unique opportunity to analyse the processes by which an ordinary foot soldier of Imperial Japan interpreted the extreme tropical war zone circumstances to which he was despatched. The thesis begins with a discussion of the discursive environment in which Tamura's diary was produced, referred to throughout the document as kokutai discourse‚ÄövÑvp in acknowledgement of the influence of the notion of kokutai ‚Äö- literally body of the nation‚ÄövÑvp but generally translated as national polity‚ÄövÑvp ‚Äö- on the socio‚ÄövÑv™political and cultural environment of pre‚ÄövÑv™war Japan. A major tension that drives the narrative of the diary is the conflict between Tamura's desire as a subject of Imperial Japan to follow kokutai teachings and lay down his life in the name of the Emperor and the contradictory desire to express a personal sense of self. In resolving this tension, Tamura often referenced the seasonal markers and the familiar natural imagery of the homeland, Japan, as a means of remaining grounded in the alien surrounds of the tropics. Memories of more favourable experiences as a soldier enabled Tamura to fantasise about a noble and glorious death.

description: Instruments play an essential role in creating research data. Given the importance of instruments and associated metadata to the assessment of data quality and data reuse, globally unique, persistent and resolvable identification of instruments is crucial. The Research Data Alliance Working Group Persistent Identification of Instruments (PIDINST) developed a community-driven solution for persistent identification of instruments which we present and discuss in this paper. Based on an analysis of 10 use cases, PIDINST developed a metadata schema and prototyped schema implementation with DataCite and ePIC as representative persistent identifier infrastructures and with HZB (Helmholtz-Zentrum Berlin für Materialien und Energie) and BODC (British Oceanographic Data Centre) as representative institutional instrument providers. These implementations demonstrate the viability of the proposed solution in practice. Moving forward, PIDINST will further catalyse adoption and consolidate the schema by addressing new stakeholder requirements.

description: This article examines how breaking a Lorentz-invariant description of nature at tiny space-time intervals would affect the non-Gaussian character of the pattern of primordial perturbations left by inflation. We specifically study a set of irrelevant operators that preserve the spatial symmetries of the usual inflationary background. The non-Gaussian component in the primordial fluctuations can be much larger than the usual, small, inflationary prediction and can thus lead to much stronger constraints on the role of "trans-Planckian" physics in inflation than those from the measurements of the primordial power spectrum.

A multiconductor transmission line with distributed compensation
Creators: name: Orton, Harry Ernest
Publisher: name: University of British Columbia
Year: 2011

description: The thesis presents an analysis of the steady-state operation of a multiconductor power transmission line with distributed compensation. The analysis outlines two methods for deriving the voltage and current equations along the line starting from Maxwell's coefficients and the Telegraph equations. Correction factors due to an imperfect earth and conductor internal impedance are discussed. Also, by making the assumption that the system of conductors is completely transposed it is shown that considerable simplification of the equations is possible. Numerical results are given for a two and a four-conductor, single phase transmission line with earth return and for a three-phase system having four conductors per phase. The results show that successful operation of the system is prevented by electric field limitations at the surface of the conductors.
D-brane orbiting NS5-branes

description: We study real time dynamics of a Dp-brane orbiting a stack of NS5-branes. It is generally known that a BPS D-brane moving in the vicinity of NS5-branes becomes unstable due to the presence of tachyonic degree of freedom induced on the D-brane. Indeed, the D-brane necessarily falls into the fivebranes due to gravitational attraction and eventually collapses into a pressureless fluid. Such a decay of the D-brane is known to be closely related to the rolling tachyon problem. In this paper we show that in special cases the decay of D-brane caused by gravitational attraction can be avoided. Namely for certain values of energy and angular momentum the D-brane orbits around the fivebranes, maintaining certain distance from the fivebranes all the time, and the process of tachyon condensation is suppressed. We show that the tachyonic degree of freedom induced on such a D-brane really disappears and the brane returns to a stable D-brane.

Self calibration of gravitational shear-galaxy intrinsic ellipticity correlation in weak lensing surveys

description: The galaxy intrinsic alignment is a severe challenge to precision cosmic shear measurement. We propose to self-calibrate the induced gravitational shear-galaxy intrinsic ellipticity correlation (the GI correlation, \citealt{Hirata04b}) in weak lensing surveys with photometric redshift measurement. (1) We propose a method to extract the intrinsic ellipticity-galaxy density cross correlation (I-g) from the galaxy ellipticity-density measurement in the same redshift bin. (2) We also find a generic scaling relation to convert the extracted I-g correlation to the demanded GI correlation. We perform concept study under simplified conditions and demonstrate its capability to significantly reduce the GI contamination. We discuss the impact of various complexities on the two key ingredients of the self-calibration technique, namely the method to extract the I-g correlation and the scaling relation between the I-g and the GI correlation. We expect none of them is likely able to completely invalidate the proposed self-calibration technique.

Aspects of the biology and ecology of six temperate reef fishes (families: Labridae and Monacanthidae).
Creators: name: Barrett, NS
Publisher: name: University Of Tasmania
Year: 2023

description: The currently most accepted population theory for reef fish was developed on tropical reefs and suggests that populations of most reef fish species are limited primarily by recruitment, with little post-recruitment resource limitation. I tested the validity of this theory for temperate reef fishes by examining growth rates in six common species from a number of isolated populations for evidence of resource limitation. If resources are limiting, spatial and temporal variation in recruitment and mortality should lead to isolated populations experiencing differing levels of resource availability, particularly food availability, which will be reflected in growth rates. I worked with six of the most common reef fishes found in Tasmanian waters so that any findings would form the basis of a broadly applicable model. These were Notolabrus tetricus, Notolabrus fucicola, Pictilabrus laticlavius, Pseudolabrus psittaculus, Penicipelta vittiger, and Meuschenia australis. Before examining growth rates it was first necessary to define the scale at which populations could be considered to be isolated. The short and long-term movement patterns of each species were studied using visual observations to interpret short-term patterns, and recaptures of tagged fish to interpret the long-term patterns. Methods of ageing each species were developed and validated, with growth rates of tagged fish being used to validate the use of otoliths for ageing. General growth curves are presented. For most of the species, there was some uncertainty in current texts about the sexual system used and the relationship between sex and dichromatism and dimorphism. To clarify this situation the reproductive biology of each species was examined. The relationship between sex and growth rate was also examined. For two species (N. tetricus and N. fucicola) annual growth data from tagged fish were obtained over a 3-4 year period, allowing inter-annual growth variability to be examined. As well as providing an insight into the variability of growth with time, these results also aid in the interpretation of growth curves determined from otolith ageing. In all species investigated, no significant differences in growth rates were detected between populations occupying similar habitats and subject to similar environmental conditions. These results suggest that post-recruitment resource limitation in the form of food limitation may not be an important factor influencing the post recruitment growth and survival of many temperate reef fishes with pelagic larval stages. This agrees with the assumptions made, but rarely tested, in current theories concerning the regulation of populations of reef fish, particularly those on temperate reefs.
A study of the human visual evoked potential
Creators: name: Bennett, John Reavely
Publisher: name: University of British Columbia
Year: 2011

description: A new approach to the study of the human Visual Evoked Potential is described, based on a simple model of the visual system. This model is then used as a tool for the investigation of the visual system and its characteristics. Certain assumptions are made concerning the spontaneous brain activity accompanying the visual response and this activity is then described by its probability density and auto-correlation functions. A theoretical basis is described for the two noise reduction techniques of ensemble averaging and the sliding mean and the implications of these processing procedures as applied to the visual system are discussed with reference to the system model. The theoretical assumptions of this analysis are then experimentally investigated. The nature of the visual response is discussed and it is shown that this response can be subdivided into two components on the basis of their time behaviour. Each of these two components, the V.E.P. and the Rhythmic After-discharge is investigated in detail. The relation of the Alpha Rhythm to the After-discharge is also investigated using auto-correlation techniques. Finally, a statistical model for the V.E.P. is described as a means for studying and applying the visual response, its uses, being discussed in some detail. An electronic coding scheme was designed to facilitate the cataloguing of experimental data, and is described in the Appendix.

We show the normal mode splitting which is due solely to reactive coupling rather than due to dispersive coupling. We suggest feeding the waveguide with a pump field along with a probe field and scanning the output probe for evidence of reactive-coupling-induced normal mode splitting.

Regional settings of structurally hosted gold mineralization in the Mudgee-Gulgong District, N.S.W.

description: The Mudgee-Gulgong district is located within the exposed northeastern margin of the Lachlan Fold Belt in New South Wales. The district was an important gold mining centre in the 1800's and produced up to 1 million ounces of gold, mostly from deep leads. Re-mapping of the area has resulted in a major revision to the stratigraphy and structural knowledge of the area. Significant changes include the recognition of the formerly known Early Devonian Burranah Formation as a Late Ordovician volcanic unit with significant exploration potential for Au-Cu mineralization. Also recognised is a Late Silurian shelf sequence with potential for Au-Cu and base metals overlying the Burranah Formation. The Burranah Formation is a dominantly submarine, volcano-sedimentary succession with a complex internal stratigraphy. Two main lithofacies associations can be recognised on the magnetic images. A lower package, composed mostly of primary volcanic rocks and minor volcaniclastics is overlain by a package composed dominantly of volcaniclastics and sediments. Small elongate intrusive bodies occur throughout the sequence. Structural interpretation of the area reveals one dominant D\\(_2\\) deformation (Early Carboniferous) that produced meridional to northwest-trending folds, cleavage, thrust faults and oblique-slip faults. A zone of higher strain is developed within the Burranah Formation and is characterised by overturned, tight, F\\(_2\\) folds and considerable shortening. Mapping and interpretation of the area has been greatly assisted by the availability of high resolution gravity, magnetic and radiometric data. The interpretation of magnetic data has considerably enhanced the structural interpretation. Volcanic and intrusive rocks of the Burranah Formation comprise a coherent calcalkaline suite with a dominantly shoshonitic character. In MORB-normalized plots, they display patterns typical of many modern subduction-related volcanics with a marked depletion of Ta and Nb and similar or lower abundances of the heavy REE and Ti. Positive ˜í¬µNd values indicate a mantle source for the shoshonites with little or no crustal contamination. Primary gold mineralization in the district occurs in veins and as disseminations in the structurally more competent rocks adjacent to faults and shear zones in the higher strain zone. Host rocks are generally intrusive monzodiorites, diorites or coherent volcanics and range in age from Late Ordovician to Early Devonian. Sulphur and lead isotope data support a syndeformational model for mineralization with fluids and gold derived from the host rock sequence.

description: The Credence Attributes On-Farm research project modelled several scenarios to reduce greenhouse gas emissions on an average Waikato dairy farm. The model found one path to producing carbon-neutral dairy products that also decreases nitrogen leaching by 42 percent. Farmers can use this research to estimate the profitability increase that may be gained through delivering three modelled credence attributes: organic, carbon-neutral, and 100% pasture-fed. The greatest potential gain is for organic (increase of 42% to 67%) and pasture-fed (increase of 36% to 49%) dairy products. Carbon-neutral products are also more profitable (increase of 11% to 25%). This research also provides an estimate of the environmental benefits of delivering the three credence attributes modelled. Carbon-neutral dairy has the greatest potential to reduce nitrogen leaching (-41% N reduction) and carbon footprint (-11 to -17%), if the farmer is able to use imported maize for 30% of the feed (as it was on the modelled farm).
Random walks in random Dirichlet environment are transient in dimension $d\ge 3$

description: We consider random walks in random Dirichlet environment (RWDE) which is a special type of random walks in random environment where the exit probabilities at each site are i.i.d. Dirichlet random variables. On $\Z^d$, RWDE are parameterized by a $2d$-uplet of positive reals. We prove that for all values of the parameters, RWDE are transient in dimension $d\ge 3$. We also prove that the Green function has some finite moments and we characterize the finite moments. Our result is more general and applies for example to finitely generated symmetric transient Cayley graphs. In terms of reinforced random walks it implies that directed edge reinforced random walks are transient for $d\ge 3$.

description: We give a method of deriving the field-strengths of all massless and massive maximal supergravity theories in any dimension starting from the Kac-Moody algebra $E_{11}$. Considering the subalgebra of $E_{11}$ that acts on the fields in the non-linear realisation as a global symmetry, we show how this is promoted to a gauge symmetry enlarging the algebra by the inclusion of additional generators. We show how this works in eleven dimensions, and we call the resulting enlarged algebra $E_{11}^{local}$. Torus reduction to $D$ dimensions corresponds to taking a subalgebra of $E_{11}^{local}$, called $E_{11,D}^{local}$, that encodes the full gauge algebra of the corresponding $D$-dimensional massless supergravity. We show that each massive maximal supergravity in $D$ dimensions is a non-linear realisation of an algebra $\tilde{E}_{11,D}^{local}$. We show how this works in detail for the case of Scherk-Schwarz reduction of IIB to nine dimensions, and in particular we show how $\tilde{E}_{11,9}^{local}$ arises as a subalgebra of the algebra $E_{11,10B}^{local}$ associated to the ten-dimensional IIB theory. This subalgebra corresponds to taking a combination of generators which is different to the massless case. We then show that $\tilde{E}_{11,D}^{local}$ appears as a deformation of the massless algebra $E_{11,D}^{local}$ in which the commutation relations between the $E_{11}$ and the additional generators are modified. We explicitly illustrate how the deformed algebra is constructed in the case of massive IIA and of gauged five-dimensional supergravity. These results prove the naturalness and power of the method.

description: We establish a polynomial recursion formula for linear Hodge integrals. It is obtained as the Laplace transform of the cut-and-join equation for the simple Hurwitz numbers. We show that the recursion recovers the Witten-Kontsevich theorem when restricted to the top degree terms, and also the combinatorial factor of the lambda_g formula as the lowest degree terms.

description: In der Bibliotheks- und Informationswissenschaft nimmt das Video-Tutorial als Medium für Informationskompetenzvermittlung beziehungsweise Information Literacy immer mehr an Bedeutung zu. Dabei stellt sich aber die Frage ob Video-Tutorials im Vergleich zu Textanleitungen überhaupt erfolgreicher in der Wissensvermittlung sind, insbesondere da Text in der Erstellung mit deutlich weniger Aufwand verbunden ist als ein Video. Die vorliegende Arbeit untersucht deshalb anhand eines qualitativen Vergleichs von Video-Tutorial und äquivalenter Text-Anleitung welches Medium sich hinsichtlich Lernerfolg und Interaktion besser gestaltet. Ziel ist es, durch den Vergleich Vor- und Nachteile des jeweiligen Mediums identifizieren und daraus Verbesserungsvorschläge für die Gestaltung von Video-Tutorials ableiten zu können.
