description: Context. It has been suggested that convection in Red Supergiant (RSG) stars gives rise to large-scale granules causing observable surface inhomogeneities. This convection is also extremely vigorous, and suspected to be one of the causes of mass-loss in RSGs. It must thus be understood in details. Evidence has been accumulated that there are asymmetries in the photospheres of RSGs, but detailedstudies of granulation are still lacking. Interferometric observations offer an exciting possibility to tackle this question, but they are still often interpreted using smooth symmetrical limb-darkened intensity distributions, or very simple spotted ad hoc models. Aims. We explore the impact of the granulation on visibility curves and closure phases using the radiative transfer code OPTIM3D. We simultaneously assess how 3D simulations of convection in RSG with CO5BOLD can be tested against these observations. Methods. We use 3D radiative-hydrodynamics (RHD) simulations of convection to compute intensity maps at various wavelengths and time, from which we derive interferometric visibility amplitudes and phases. We study their behaviour with time, position angle, and wavelength, and compare them to observations of the RSG alpha Ori Results. We provide average limb-darkening coefficients for RSGs. We detail the prospects for the detection and characterization of granulation (contrast, size) on RSGs. We demonstrate that our RHD simulations provide an excellent fit to existing interferometric observation of alpha Ori, contrary to limb darkened disks. This confirms the existence of large convective cells on the surface of Betelgeuse.

Outdoor recreation in Tasmania's state forests : challenges and opportunities
Creators: name: Branigan, S
Publisher: name: University Of Tasmania
Year: 2023

description: Forestry Tasmania has a mandate enshrined in the Forestry Act 1920 to manage State forest areas for multiple use purposes. This research critically assesses the governance of States forests in the Huon Forest District and the provision of outdoor recreational opportunities. A qualitative research approach was employed utilising a multiple method approach. These methods included a literature review, semistructured key stakeholder interviews and a Recreational Opportunity Spectrum (ROS) planning framework. Results generated from these analyses were synthesised using a data triangulation process to identify the emergent themes. The conflicts that arise in multiple use management of forests were most strongly evident in stakeholders' perceptions and highlighted that wood production imperatives dominate planning decisions. Forest management is regulated through the forest practices system, however, there are no provisions encompassed in the forest practices code to guide the on-ground identification of recreational values alongside natural, cultural and timber assessments. Public consultation procedures were perceived as being conducted in a top-down authoritative manner with a collective sense of disempowerment portrayed by the respondents. Semi-remote forested landscapes appear to be a diminishing recreational setting in State forests with future demand for outdoor activities proposed to be orientated towards these areas. Stakeholders advocated a comprehensive inventory of recreational values to be undertaken for all Forest Districts. The ROS framework proved to be a useful means of assessment which could assist in further fulfilling Forest Tasmania's multiple use mandate

description: No abstracts are to be cited without prior reference to the author. Due to the implementation of spatial management measures such as the designation of areas for offshore wind development or fishing regulations within Nature 2000 sites, fishing activities within the German Exclusive Economic Zone (EEZ) of the North Sea will be increasingly displaced. To support the implementation of an ecosystem approach to marine management, we assess the dynamics of both, ecosystem components such as modelled nursery grounds of flatfish species as well as human drivers such as German fishery fleets on temporal and spatial scales. Furthermore, different spatial co-use options for the coupling of offshore aquaculture and offshore wind farms are assessed to identify potential synergies between human activities. Based on these findings, spatial management scenarios are evaluated across the German management objectives using decision support software. Here, the procedure as well as the main findings are summarised in order to demonstrate the applicability of the tools and methods and the need for an ecosystem-based approach to Marine Spatial Planning (MSP) using the German EEZ as a case study area

description: No abstracts are to be cited without prior reference to the author. From 2007 until present a total of 11 species of the potentially toxigenic genera Azadinium and Amphidoma, a closely related, also toxigenic genus, have been discovered. However, among the eleven species azaspiracids (AZAs) have been found in only four of them. The first known AZA-prod ucing species A. spinosum produces only AZA-1, -2 -33 and -34, but by now eight other AZAs have been discovered to be from dinoflagellate origin . Especially A. poporum have been shown to possess highly variable AZA profiles consisting of AZA-2, -36, -37, -40, -41 and -42 in various combinations includ ing non-toxigenic strains. Among the AZAs of d inoflagellate origin, three structural types have been found: the 362-, 360- and 348-type, differing in the methylation and unsaturation of the H,I-ring system of the molecules. Until recently AZP appeared to be a merely European problem, but there is increasing evidence that Azadinium and Amphidoma and their respective AZAs have a worldwide distribution including the entire Pacific, the northern and south western Atlantic and thus may be a potential AZP risk elsewhere as well.

description: Particles in a perfect lattice potential perform Bloch oscillations when subject to a constant force, leading to localization and preventing conductivity. For a weakly-interacting Bose-Einstein condensate (BEC) of Cs atoms, we observe giant center-of-mass oscillations in position space with a displacement across hundreds of lattice sites when we add a periodic modulation to the force near the Bloch frequency. We study the dependence of these "super" Bloch oscillations on lattice depth, modulation amplitude, and modulation frequency and show that they provide a means to induce linear transport in a dissipation-free lattice. Surprisingly, we find that, for an interacting quantum system, super Bloch oscillations strongly suppress the appearance of dynamical instabilities and, for our parameters, increase the phase-coherence time by more than a factor of hundred.

description: No abstracts are to be cited without prior reference to the author. Species of the dinoflagellate genus Gambierdiscus are responsible of Ciguatera Fish Poisoning (CFP) which is very common in tropical areas, mainly the Pacific Ocean and Caribbean Sea. Until 2008 this disease was not reported in the NE Atlantic Ocean, when human intoxications after consumption of local fish have been reported almost yearly in the Canary Islands. Sampling on rocky shores of this archipelago revealed an unexpected diversity of the genus Gambierdiscus. Morphological and phylogenetic study established the presence of at least 3 species: G. excentricus (described in the Canaries), G. australes, and a third species (G. silvae sp nov.), close to G. polynesiensis and Gambierdiscus sp. type 4 sensu Xu et al. (2014). The evaluation of their toxicity was performed by mouse bioassay (MBA) and erythrocyte lysis assay (ELA). Additionally, identification of the CTXs congeners were conducted using liquid chromatography (LC) coupled with high resolution mass spectrometry (HRMS). Nevertheless, the link between local Gambierdiscus populations and ciguateric fish has not been unambiguously demonstrated. Future studies should focus on the phylogeography of Gambierdiscus, their distribution, abundance, and the characterization of ciguatoxins in cultures vs those in local fishes to understand if these are accumulated in Canaries or other areas
A method for the computer analysis of music utilizing the IBM 360 digital computer

Publisher: name: University of British Columbia
Year: 2011

description: A method for the computer analysis of certain melodic and rhythmic elements, such as intervals, range, and frequency of occurrence of elements, of selected musical works is presented and results are obtained. The method also utilizes new techniques of musical analysis which would otherwise be too lengthy or cumbersome to be practical, i.e., information-content, redundancy, and autocorrelation. The analytical results are discussed and both the method and the results are evaluated with a view to alteration and expansion leading to a more comprehensive analysis of music.
Municipal reforms in Tasmania : the impact of the purchaser-provider split on service delivery in Hobart and Sorell councils
Creators: name: Abdulai, KM
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the purchaser-provider split in the contexts of two Tasmanian local government areas ‚ÄövÑvÆ Hobart and Sorell. In particular, it addresses whether the focus of the purchaser has been redirected in a way that prioritises the assessment and meeting of the needs of public service customers over the hitherto preoccupation with service production. This implies a clear shift of emphasis from inputs and processes to outputs and outcomes. In proceeding with that assessment, other research is reviewed along with the presentation of the results of the council case studies. The study investigates whether that split has had an effect on councils' total service spending, employment and organisational culture and practices. The behaviour of these variables over time then provides the basis for determining whether there is an asymmetry in outcomes between the two councils as a result of the introduction of the purchaser-provider split. The thesis uses a longitudinal research design to analyse data collected from interviews and secondary sources such as reports, strategic and annual plans, and newsletters. This thesis finds that local governments in Tasmania are still preoccupied with inputs and processes regardless of whether services are delivered by internal or external providers. The purchaser-provider split has been found to be unrelated to service category-level spending. The introduction of the model has not led to reductions in total municipal service spending but has decreased employment. The impact of the split on quality of services is unknown. Concern with outputs is evident although this has a weak relation to outcomes. The purchaser's attention has been drawn more to achieving outputs than outcomes, even though both are supposedly its responsibility. This evidence, although mixed, does serve to qualify earlier research results which posited improvements in delivery outcome through the split for some services.

description: (Abridged) The present number of Galactic Open Clusters that have high-resolution abundance determinations, not only of [Fe/H], but also of other key elements, is largely insufficient to enable a clear modeling of the Galactic Disk chemical evolution. We obtained high-resolution (R~30000), high quality (S/N~50-100 per pixel), echelle spectra with FOCES, at Calar Alto, for 3 red clump stars in each of five Open Clusters. We used the classical Equivalent Width analysis method to obtain accurate abundances of 16 elements. We also derived the oxygen abundance through spectral synthesis of the 6300A forbidden line. Three of the clusters were never studied previously with high-resolution: we found [Fe/H]=+0.03 +/- 0.02 dex for Cr110; [Fe/H]=+0.01 +/- 0.05 dex for NGC2099 (M37) and [Fe/H]=-0.05 +/- 0.03 dex for NGC2420. For the remaining clusters, we find: [Fe/H]=+0.05 +/- 0.02 dex for M67 and [Fe/H]=+0.04 +/- 0.07 dex for NGC7789. We provide the first high-resolution based velocity estimate for Cr110, V=41.0 +/- 3.8 km/s. All our programme stars show abundance patterns typical of open clusters. Also, no significant sign of (anti-)correlations is found. We then compile high-resolution data of 57 clusters from the literature and we find a gradient of [Fe/H] with Galactocentric Radius of -0.06 +/- 0.02 dex/kpc, in agreement with past work. A change of slope is seen outside RGC=12 kpc and [alpha/Fe] shows a tendency of increasing with RGC. We also confirm the absence of a significant Age-Metallicity relation.

description: No abstracts are to be cited without prior reference to the author. Life Cycle Assessment (LCA) quantifies environmental impacts of products, primarily regarding emission-based impacts such as greenhouse gas emissions, acidification and eutrophication. Indicators to quantify also biotic impacts of fishing in relation to seafood products have recently been presented. Fuel use in fishing often drives the emission-based LCA impacts. As fuel data is scarce, especially on a detailed level, we present an approach for utilizing official fleet-wide fuel data to estimate the fuel use of individual fisheries. We show that the fuel efficiency of Swedish demersal trawl fisheries has improved. The difference in fuel efficiency per kilo landed between large and small trawlers was small, unless catch capacity was lowered by use of species-selective grids. Stock rebuilding was shown to determine fuel use, as fuel efficiency was correlated to increasing biomass of Eastern Baltic cod. However, rebuilding efforts can also lead to tradeoffs e.g. in the case of selective crustacean trawling; protection of depleted fish stocks decreases the fuel efficiency per landing. Results suggest that fuel use is one of several important indicators for sustainable fisheries that should be considered by fisheries management and certification, motivated by the great importance of fuel use for both environmental and economic performance of fisheries

description: We have used the Very Large Array (VLA) at 7 mm wavelength to image five rotational transitions (J=1-0) from three SiO isotopologues towards Orion BN/KL: 28SiO v=0,1,2; and 29SiO and 30SiO v=0. For the first time, we have mapped the 29SiO and 30SiO J=1-0 emission, established the maser nature of the emission, and confirmed association with the deeply embedded high-mass young stellar object commonly denoted radio Source I. The 28SiO v=0 maser emission shows a bipolar structure that extends over ~700 AU along a northeast-southwest axis, and we propose that it traces a bipolar outflow driven by Source I. The high-brightness isotopic SiO maser emission imaged with a ~0.2 arcsec resolution has a more compact distribution, generally similar to that of the 28SiO v=1,2 emission, and it probably traces bulk gas flows in a region of diameter <100 AU centered on Source I. On small scales of <10 AU, however, compact 29SiO/30SiO v=0 and 28SiO v=1,2 emission features may be offset from one another in position and line-of-sight velocity. From a radiative transfer analysis based on a large velocity gradient (LVG) pumping model, we derive similar temperatures and densities for the optimum excitation of both 29SiO/30SiO v=0 and 28SiO v=1,2 masers, significantly higher than required for 28SiO v=0 maser excitation. In order to account for the small-scale differences among the isotopologues (v=0) and the main species (v=1,2), follow-up radiative transfer modeling that incorporates non-local line overlap among transitions of all SiO isotopic species may be required.

description: We investigate the intensity and polarization of reflected light from planetary atmospheres. We present a large grid of Monte Carlo simulations for planets with Rayleigh scattering atmospheres. We discuss the disk-integrated polarization for phase angles typical of extrasolar planet observations and for the limb polarization effect observable for solar system objects near opposition. The main parameters investigated are single scattering albedo, optical depth of the scattering layer, and albedo of an underlying Lambert surface for a homogeneous Rayleigh scattering atmosphere. We also investigate atmospheres with isotropic scattering and forward scattering aerosol particles, as well as models with two scattering layers. The model grid provides a tool for extracting quantitative results from polarimetric measurements of planetary atmospheres from solar system planets and extrasolar planets, in particular on the scattering properties and stratification of particles in the highest atmosphere layers. Spectropolarimetry of solar system planets offers complementary information to spectroscopy and polarization flux colors can be used for a first characterization of exoplanet atmospheres. From limb polarization measurements, one can set constraints on the polarization at large phase angles.

An analysis and evaluation of contemporary international initiatives to eliminate illegal, unreported and unregulated fishing : market-based measures, the FAO global record of fishing vessels, and the FAO agreement on port state measures
Creators: name: Broweleit, J
Publisher: name: University Of Tasmania
Year: 2023

description: Illegal, unreported and unregulated fishing (IUU fishing) exists in most fisheries and is considered by the United Nations to be the main obstacle to achieving sustainable fisheries.' It persists primarily because of a widespread failure of flag State control. Eradicating IUU fishing requires coordinated responses by coastal States, port, market and flag States and Regional Fisheries Management Organisations. This dissertation focuses on IUU fishing of marine capture fish stocks, both within the 200 mile Exclusive Economic Zone and the high seas. It will not deal with inland fisheries or national problems with illegal fishing or poaching. It analyses two international proposals currently in development: a Global Record of fishing vessels and a Port State Measures Agreement. These initiatives seek to address three major problems: a) inadequate data on the state of IUU fishing and the size, scope and activities of the world's fishing fleet; b) flag State ineffectiveness; and c) the limited use of market-based measures. This dissertation is an evaluation of the likely success of these new initiatives in combatting IUU fishing. It submits that despite the significant challenges facing the passage and adoption of a Global Record of fishing vessels and the Port State Measures Agreement, they must be implemented in order to shut down major gaps in the coverage and efficacy of the current international fisheries regime. This dissertation further submits that greater, more coordinated use of both public and private trade and market-related measures must be made in order to support the two proposed instruments.

description: LTE abundances of light elements in extremely metal-poor (EMP) stars have been previously derived from high quality spectra. New derivations, free from the NLTE effects, will better constrain the models of the Galactic chemical evolution and the yields of the very first supernovae. The NLTE profiles of the magnesium and potassium lines have been computed in a sample of 53 extremely metal-poor stars with a modified version of the program MULTI and adjusted to the observed lines in order to derive the abundances of these elements. The NLTE corrections for magnesium and potassium are in good agreement with the works found in the literature. The abundances are slightly changed, reaching a better precision: the scatter around the mean of the abundance ratios has decreased. Magnesium may be used with confidence as reference element. Together with previously determined NLTE abundances of sodium and aluminum, the new ratios are displayed, for comparison, along the theoretical trends proposed by some models of the chemical evolution of the Galaxy, using different models of supernovae.

description: Low-loss microwave components are used in many superconducting resonant circuits from multiplexed readouts of low-temperature detector arrays to quantum bits. Two-level system defects in amorphous dielectric materials cause excess energy loss. In an effort to improve capacitor components, we have used optical lithography and micromachining techniques to develop superconducting parallel-plate capacitors in which lossy dielectrics are replaced by vacuum gaps. Resonance measurements at 50 mK on lumped LC circuits that incorporate these vacuum-gap capacitors (VGCs) reveal loss tangents at low powers as low as 4x10^{-5}, significantly lower than with capacitors using amorphous dielectrics. VGCs are structurally robust, small, and easily scaled to capacitance values above 100 pF.

description: No abstracts are to be cited without prior reference to the author. Suspension-feeding bivalves are often exposed to cyanobacterial blooms, commonly concentrating cyanotoxins. A higher efficiency of the detoxification process might enable organisms to endure toxic cyanobacterial mass occurrences. Biotransformation and excretion capacities for cyanobacteria have been demonstrated for several bivalves including for Mytilus galloprovincialis. In this way, a proteomic approach was used in this mussel for a qualitative study of changes in Glutathione Transferases (GSTs) expression induced by a toxic Microcystis aeruginosa strain (LEGE 91094). Mussels were exposed to living Microcystis cells, crude Microcystis extracts and pure toxins during 24 hours. GST cytosolic fractions from gills and digestive tract were purified by glutathione-agarose affinity chromatography and the collection of expressed GST classes of each organ analyzed by twodimensional (2-D) electrophoresis in 7 cm IPG strips (pH 5–8). Proteomic approach was successful at detecting peptides representing the collection of expressed cytosolic GST subunits in M. galloprovincialis gills and digestive tract. Preliminary results denote altered protein expression in both tissues according to the several treatments.

description: Epigenetic variation modulates gene expression and can be heritable. However, knowledge of the contribution of epigenetic divergence to adaptive diversification in nature remains limited. The massive evolutionary radiation of Lake Malawi cichlid fishes displaying extensive phenotypic diversity despite extremely low sequence divergence is an excellent system to study the epigenomic contribution to adaptation. Here, we present a comparative genome-wide methylome and transcriptome study, focussing on liver and muscle tissues in phenotypically divergent cichlid species. In both tissues we find substantial methylome divergence among species. Differentially methylated regions (DMR), enriched in evolutionary young transposons, are associated with transcription changes of ecologically-relevant genes related to energy expenditure and lipid metabolism, pointing to a link between dietary ecology and methylome divergence. Unexpectedly, half of all species-specific DMRs are shared across tissues and are enriched in developmental genes, likely reflecting distinct epigenetic developmental programmes. Our study reveals substantial methylome divergence in closely-related cichlid fishes and represents a resource to study the role of epigenetics in species diversification.

description: The GEOSCOPE network (G) is a global seismological network created in 1982 to respond to the challenge of instrumenting isolated sites all around the world. The GEOSCOPE network is primarily dedicated to research and its data are used for studies of Earth structure and dynamics, seismic sources, time dependent seismology and environmental seismology. It currently runs 33 broad band seismic stations, all of which provide real-time data. This allows for rapid source determination, and GEOSCOPE data are therefore used by earthquake and tsunami alert centers. Most of the stations are equipped with very broad band STS1 seismometers and recent installations now include new generation very broadband sensors (STS6, T360). Stations are either installed in vaults with special equipments aimed at reducing long period noise related to atmospheric pressure variation, or at depth to reduce surface perturbations.
Data of this network are freely and fully disseminated (both in real time and after validation) with standardized format and distribution procedures by the IPGP, RESIF and IRIS data centers.
IPGP data center also provides additional products built with GEOSCOPE data, such as near real-time estimation of global seismicity source parameters (for earthquakes above magnitude 5.5-6).

description: No abstracts are to be cited without prior reference to the author. Life Cycle Assessment (LCA) quantifies the environmental impact of products, often using annual average data. Fisheries often show high spatial and temporal variability and annual values may be too coarse to identify causes and improvement options on an appropriate level. Using LCA methodology, we analysed two years of data of a demersal freeze trawler targeting cod, haddock, saithe and shrimp mainly in the Norwegian and Barents Seas. The product was a kg of landing from one fishing trip, frozen at sea. We quantified standard LCA impacts and biotic indicators (e.g. impacts on target and by-catch stocks) showing large variation between fishing trips. Fuel use was the main driver of emission-based impacts. Shrimp trawling was more fuel intensive than fish trawling per kg of landing, due to lower catch rates. Bycatch (catch of species other than the main target species) was low due to use of a species-selective grid in shrimp trawling. Fish trawling required less fuel, but landed varying amounts of bycatch. Quantifying environmental impacts of seafood products on a fine scale could help fishing companies, managers and certifiers to better understand the effect of decision-making on the environmental performance of seafood products.

description: The article reviews recent progress in the theoretical understanding of near-field surface electromagnetic phenomena in pristine and atomically doped carbon nanotubes. The phenomena involving strong coupling effects are outlined. They are the optical absorption by single-walled carbon nanotubes doped with single atoms or ions in the frequency range close to the atomic transition frequency, the entanglement of the pair of atomic qubits strongly coupled to a common high-finesse surface photonic mode of the nanotube, and the optical response of the strongly coupled surface exciton-plasmon excitations in pristine semiconducting carbon nanotubes. The phenomena reviewed have a great potential to be exploited for the future development of the nanotube based tunable optoelectronic device applications in areas such as nanophotonics, nanoplasmonics, cavity quantum electrodynamics, and quantum information science.

description: The haplotype resolution from xor-genotype data has been recently formulated as a new model for genetic studies. The xor-genotype data is a cheaply obtainable type of data distinguishing heterozygous from homozygous sites without identifying the homozygous alleles. In this paper we propose a formulation based on a well-known model used in haplotype inference: pure parsimony. We exhibit exact solutions of the problem by providing polynomial time algorithms for some restricted cases and a fixed-parameter algorithm for the general case. These results are based on some interesting combinatorial properties of a graph representation of the solutions. Furthermore, we show that the problem has a polynomial time k-approximation, where k is the maximum number of xor-genotypes containing a given SNP. Finally, we propose a heuristic and produce an experimental analysis showing that it scales to real-world large instances taken from the HapMap project.

description: Recent discoveries of transmissible cancers in multiple bivalve species suggest that direct transmission of cancer cells within species may be more common than previously thought, particularly in aquatic environments. Fibropapillomatosis occurs with high prevalence in green sea turtles ( Chelonia mydas) and the geographic range of disease has increased since fibropapillomatosis was first reported in this species. Widespread incidence of schwannomas, benign tumours of Schwann cell origin, reported in aquarium-bred goldfish (Carassius auratus), suggest an infectious aetiology. We investigated the hypothesis that cancers in these species arise by clonal transmission of cancer cells. Through analysis of polymorphic microsatellite alleles, we demonstrate concordance of host and tumour genotypes in diseased animals. These results imply that the tumours examined arose from independent oncogenic transformation of host tissue and were not clonally transmitted. Further, failure to experimentally transmit goldfish schwannoma via water exposure or inoculation suggest that this disease is unlikely to have an infectious aetiology.

description: Parents who experience poverty and who want to provide their children with an escape route can be expected to encourage and support their progeny’s education. The evidence that Roma parents behave differently is unsettling. In this paper we test empirically an explanation for that behavior. The explanation is based on a theory (Stark et al. 2018) that can be “borrowed” to rationalize the enforcement of norms of little formal education in underprivileged communities. An analysis of survey data collected in Roma communities in four Central and Eastern European countries lends support to the explanation. The analysis reveals a strong negative correlation between the influence of the Roma community on an individual member’s life and the importance accorded by the individual to formal schooling for children. The correlation is robust to controlling for standard determinants of attitudes towards schooling, such as poverty, unemployment, labor market discrimination, and parents’ educational attainment. The analysis suggests that policy interventions aiming to increase the formal education of Roma children need to reckon with the influence of Roma community norms on individual choices.

description: Research was and still is involved in the controversial issue about innate talent or extensive practice as the determinants of excellent performance in a range of domains. This study aims to contribute by presenting an analysis of practice activities in a domain that appears to be particularly suitable—orchestral conducting. Most conductors usually attain expertise in instrument playing prior to commencing conducting studies. Twenty-seven students of German study programs of orchestral conducting (approximately 18.7% of the population) responded to a questionnaire about their practice activities in conducting programs and their instrumental experiences. Descriptive results show the wealth of prestudy experiences conducting students have. A clear influence on practice activities cannot be stated. During study, students rated conducting-specific practice activities as more demanding and devoted more time to them than to general music practice activities. Therefore, conducting-specific practice activities might have been practiced more deliberately than general music practice activities.
On the derivation of structural models with general thermomechanical prestress

description: The vibrating behaviour of thin structures is affected by prestress states. Hence, the effects of thermal prestress are important research subjects in view of ambient vibration monitoring of civil structures. The interaction between prestress, geometrically non-linear behaviour, as well as damping and its coupling with the aforementioned phenomena has to be taken into account for a comprehensive understanding of the structural behaviour. Since the literature on this subject lacks a clear procedure to derive models of thin prestressed and damped structures from 3D continuum mechanics, this paper presents a new derivation of models for thin structures accounting for generic prestress, moderate rotations and viscous damping. Although inspired by classical approaches, the proposed procedure is quite different, because of (i) the definition of a modified Hu-Washizu (H-W) functional, accounting for stress constraints associated with Lagrange multipliers, in order to derive lower-dimensional models in a convenient way; (ii) an original definition of a (mechanical and thermal) strain measure and a rotation measure enabling one to identify the main terms in the strain energy and to derive a cascade of lower-dimensional models (iii) a new definition of "strain-rotation domains" providing a clear interpretation of the classical assumptions of "small perturbations" and "small strains and moderate rotations"; (iv) the introduction of a pseudo-potential with stress constraints to account for viscous damping. The proposed procedure is applied to thin beams.

description: No abstracts are to be cited without prior reference to the author. Marine spatial planning such as under the German Maritime Spatial Plan may help assist with the implementation of ecosystem-based management under the MSFD while MSFD may help to generate information from monitoring for spatial planning purposes under the Maritime Spatial Plan. One of the identified common high level objectives between MSFD and the German Maritime Spatial Plan is the protection of biodiversity and ecological functions and processes. Therefore, a first attempt of spatio-temporal representation of biodiversity relevant MSFD indicators at the species level is presented here for demersal finfish as well as additional metrics such as Hill Numbers and a metric for functional diversity. Analysis was based on spatially well distributed data across the German EEZ and adjacent water of the North Sea. Multivariate methods such as Generalised additive models were combined with geostatistical methods to produce distributional maps per assessment year.

description: We describe some properties of noncompact Euclidean cone manifolds with cone angles less than c less than 2pi and singular locus a submanifold. More precisely, we describe its structure outside a compact set. As a corollary we classify those with cone angles less than 3pi/2 and those with all cone angles equal to 3pi/2.

description: The article is devoted to the system analysis of the creation and implementation of a set of balanced indicators of organizational performance. The main mistakes that companies make during this process are considered. As a research task, the author identified an attempt to formulate the basic rules for constructing a hierarchy of goals and systematize the restrictions that must be taken into account when creating a set of balanced indicators, including those related to the corporate information system. The main objective of the study is to identify problems that prevent the successful application of this management tool in practice.
