The effect of oxygen supplementation on brachial artery hemodynamics and vascular function during trekking ascent to high altitude
Creators: name: Vizcardo-Galindo, Gustavo
Publisher: name: University of British Columbia
Year: 2023

description: High altitude trekking alters upper limb hemodynamics and reduces brachial artery vascular function in lowlanders. However, whether these changes are reversible with the correction of hypoxia is unknown. We investigated the impact of 15 minutes of oxygen supplementation (O₂) on brachial artery hemodynamics, reactive hyperemia (microvascular function) and flow-mediated dilation (FMD; endothelial function). Healthy male participants (aged 21-42 years) were examined prior to and with O₂ at 3440m (day 4 at high altitude; n=7), 4371m (day 7; n=7), and 5050m (day 10; n=12) using Duplex ultrasound. At 3440m, O₂ decreased brachial artery diameter (-5±5%; P=0.04), baseline blood flow (-44±15%; P<0.001), oxygen delivery (-39±16 P<0.001) and peak reactive hyperemia (-8±8%; P=0.02). Although at 3440m O₂ elevated FMD (P=0.04), this was attributed to the reduction in baseline diameter (allometrically-scaled FMD, P=0.145). Only antegrade shear stress was reduced by O₂ at 4371m (P=0.026). However, at 5050m, a reduction in brachial artery blood flow (-17±22%; P=0.03), but not oxygen delivery, diameter, reactive hyperemia or FMD occurred with O₂. Collectively, these findings suggest that O₂ causes vasoconstriction in the upper limb along the arterial tree (conduit and resistance arteries), limiting oxygen delivery and reactive hyperemia during early trekking at high altitude. With prolonged, more severe high-altitude exposure, O₂ reduces blood flow in the upper limb without compromising oxygen delivery, reactive hyperemia or FMD. Therefore, supplemental oxygen appears to have differential impacts on vascular function that are modulated by the duration and severity of high-altitude exposure.

description: We study the generalized quantum isotonic oscillator Hamiltonian given by H=-d^2/dr^2+l(l+1)/r^2+w^2r^2+2g(r^2-a^2)/(r^2+a^2)^2, g>0. Two approaches are explored. A method for finding the quasi-polynomial solutions is presented, and explicit expressions for these polynomials are given, along with the conditions on the potential parameters. By using the asymptotic iteration method we show how the eigenvalues of this Hamiltonian for arbitrary values of the parameters g, w and a may be found to high accuracy.

For more than a decade, re3data (https://www.re3data.org/), the global registry of research data repositories, has helped researchers, funding agencies, libraries, and other research data services to find, identify, and reference research data repositories. As the world's largest directory of data repositories, re3data describes over 3100 infrastructures on the basis of its comprehensive metadata schema in May 2023. The service allows searching for research data repositories of any type and from all disciplines, and users can filter results based on a wide range of characteristics. The re3data descriptions are openly accessible via an API and are reused by numerous open science services, including DataCite Commons. re3data is engaged in various initiatives and projects concerning data management and is mentioned in the policies of scientific institutions, funding organizations, and publishers.

The presentation will focus on the growth, development, and accomplishments of re3data over more than 10 years that have resulted in re3data becoming the most comprehensive information and metadata resource on research data repositories. Further, the presentation will address how re3data’s activities can support the establishment of best practices, support open science, and facilitate networking within different research communities. With over 850 entries the field of geosciences is one of the most strongly represented subject groups in the registry.

description: For our participation in CLEF, the Berkeley group participated in the monolingual, multilingual and GIRT tasks. To help enrich the CLEF relevance set for future training, we prepared a manual reformulation of the original German queries which achieved excellent performance, more than 110% better than average of median precision. The GIRT task performed English- German Cross-Language IR by comparing commercial machine translation with thesaurus lookup techniques and query expansion techniques. Combining all techniques using simple data fusion produced the best results.

description:
Geoscientists know that their scientific understanding of the Earth as a system is important for the sustainable development of planet Earth. In Germany they expressed their concern about the state of geoscience education in 1996 (Leipziger Erklärung) and in 2023 (Positionspapier der GEOUNION und des Dachverbandes der Geowissenschaften). Explicit geoscience education expertise is still lacking at all levels of the educational system: education research at the universities, teacher training, professional development of teachers, syllabus commissions.

In 2019 the European Geoscience Union - Education Commission (EGU-EC) launched an initiative by appointing Geoscience Education Field Officers (GEFO) to support science and geography teachers that are interested in teaching geosciences. The GEFO are trained to offer in service and pre service teacher training according the teacher training method developed by the Earth Science Education Unit originally based at Keele University (UK). It provides interactive hands-on workshops and access to a wealth of teaching resources that are freely available through a website. The workshops are evaluated by an online questionnaire. (Correia et al. 2020).

In 2022 the EGU-EC appointed a GEFO for Germany. Measures of cooperation have been established and first workshops conducted. Cooperation partners as well as German teachers show a high level of interest in the workshops. The workshop schedule will be explained and first evaluation results presented.

“That’s what she said!” : gender integration in the Canadian Armed Forces with a focus on the experience of female soldiers in the combat arms
Creators: name: Franck, Billie
Publisher: name: University of British Columbia
Year: 2023

description: This thesis focuses on gender integration in the Canadian Armed Forces (CAF) based on veteran female combat arms soldiers' experiences. I argue that the military institution presents itself as progressive and gender neutral but is, in fact, a gendered institution with distinct organizational thinking that maintains gender segregation. The federal government's goal of increasing the number of female soldiers employed in the CAF to 25 % by 2026 is too broad and does not address the systemic issues rendered invisible when institutional change is desired. The division of labour, based on military occupations with the least number of female soldiers, exacerbates the social relations and the organizational logic, which maintains the low representation of female soldiers. I focus on the combat arms occupations because these occupations have historically had the most resistance to female integration and have the most prestige and proximity to the fighting. I treated the disembodied soldier as a universal category that is abstract and gender neutral and used to determine types of bodies acceptable for different military occupations. Therefore, I argue that the ideal soldier is, in fact, heavily gendered towards male bodies, masculinity, and male heterosexuality. This ideology shapes views on what bodies are most qualified to do the work of combat, fighting, and sacrificing for the nation. And only when the idea of females doing combat enters the conversation do we see the social relations and gender assumptions that maintain the CAF's gender order and foster a culture harmful to female soldiers. For example, the underlying sexualized culture in the Forces is conducive to more severe incidents of sexual harassment and assault (Deschamps, 2015). Therefore, for cultural change to occur, we need to see a fundamental shift in the CAF's thinking of the ideal soldier and show what social relations surrounding work as a soldier will look like.

description:
The early Mississippian of the Aachen region is characterized by a tropical shallow-water carbonate succession, the so-called Kohlenkalk Platform. Establishing a second phase of intensive carbonate production, it follows on the Givetian to Frasnian biostromal buildups around the southeastern edge of the London-Brabant Massif. The timing and patterns of the development of these Carboniferous carbonates were studied, based on drill core Gressenich BK1. It was sunk by the Geological Survey of North Rhine-Westphalia in the core of the Burgholz Syncline and reached a depth of 100 metres. The borehole is located in the Vygen/Gressenich Quarry, which exposed and strongly tectonized Devonian strata were previously investigated by Reißner (1990). In contrast to the nearby active Hastenrath Quarry, the Palaeozoic part of the succession shows an inverted stratification. As Holocene sediments comprise a thickness of 7.30 m within the drill core, subsequent Devonian sedimentary rocks (mostly reefal limestones) occur up to a depth of 27.00 m. Followed by 12.40 m of black shale of unclear stratigraphic age, possibly the Frasnian Matagne Shale, all formations and subformations of the drilled Kohlenkalk succession can be easily subdivided by lithostratigraphy. Considering the regional stratigraphic schemes in the Vesdre Massif of eastern Belgium and referring to the formal lithostratigraphic concept of Amler & Herbig (2006), these are the Vesdre and Terwagne formations. The latter contains the Hastenrath (= Vaughanites Oolith), Bärenstein, and Bernardshammer subformations. Unfortunately, conodonts are rare or absent. In the case of the Vaughanites Oolith, reworking processes cannot be ruled out.

With the main goal of supporting geosciences education in Europe and beyond, the European Geosciences Union (EGU) Education Committee (EC) launched and support the Geoscience Education Field Officers (GEFO) programme. A GEFO is a teacher trainer that promotes hands-on workshops to geoscience teachers and pre-service teachers, from primary to secondary school, in his own country. Since 2019, a network of 11 EGU GEFO are working, initially with members from France, Italy, Portugal, and Spain, later reinforced, in May 2022, with GEFO from Albania, Estonia, Germany, Greece, Romania, Turkey, and the United Kingdom. Beyond Europe GEFO programme is established in eight countries (Burkina Faso, Chile, Colombia India, Malaysia, Morocco, Togo) and is supported by the International Union of Geological Sciences Commission on Geoscience Education (IUGS-COGE). Indicators as: a) number of workshops held, attending participants, and locations; b) workshop contents; c) teachers’ conferences attended and abstracts/papers published by GEFO about their activity; d) and an evaluation form provided to attending participants that allows to make a sample characterisation (teacher education establishments involved, gender, role, teaching years, professional position, school level, taught subjects) and appreciation of the interest of the workshops, have been used to assess the progress of the programme. The evaluation form was adapted from one used by the Earth Science Education Unit (University of Keele, UK). The assessment has brought some challenges particularly related to the application of the same evaluation form in different national educational systems/curricula, and with the encouragement of attends to fill in the form.

description:
The depth of the critical zone, the zone that spans from the canopy to the weathering front in the subsurface, is mostly unknown due to its inaccessible nature. To identify the depth of the critical zone and infer its assumed control by water flow we conducted four drilling campaigns in granitoid rock along a climate gradient in the Chilean Coastal Cordillera. The drilled cores differ in the depth of the weathering front between arid, semi-arid, mediterranean, and humid climate. The arid study site is located at the southern end of the Atacama Desert and the drill core is hydrothermally overprinted. No chemical top-down weathering or physical disintegration of the granitic rock is found. The semi-arid drill core reveals multiple weathering fronts along fractures and shows top-down chemical weathering in the uppermost 10 m. In the mediterranean study site, we found the deepest weathering front with saprolite to a depth of ~45 m, followed by bedrock with wide fractures. The physical disintegration is stronger than chemical mass losses due to weathering. The humid study site is characterised by a shallow weathering front at ~10 m depth. Even though sufficient water is available to form a deep weathering zone, the formation of clay and other secondary minerals inhibits further advance of the weathering front by clogging pore space thus preventing water flow. We conclude while the of degree of (chemical) weathering is set by climate, the depth of the weathering front depends on the abundance and width of tectonic fractures.

description:
CO2 neutrality by 2045 requires increasing the currently worldwide achieved CO2 storage volume (40 Mt/y) to the order of tens of Gt/y. With current storage techniques, CO2 often remains in the gaseous phase, thus, free to spread underground risking unwanted leakage in the distant future. As an alternative, the mineralization of CO2 in basalts, where the vast majority (>90%) of the carbon is mineralized and fixed in carbonates within two years, offers a permanent safe storage as a solid (e.g. CarbFix, Iceland).
The international joint project PERBAS (ACT4) with partners from Norway, USA and India aims to pave the way for the commercialization of large-scale, permanent CO2 sequestration into marine basalt complexes off the coast of Norway and India. The project seeks solutions for reservoir selection, CO2 transport, injection and monitoring. PERBAS will investigate the feasibility of supercritical CO2 injection, using water in the pore space, in order to avoid the requirement to inject 20 t of water for 1 t of CO2. This would have the additional advantage that supercritical CO2 would be associated with a free gas phase, which allows the application of geophysical remote sensing for monitoring thereby reducing the number of monitoring wells required.
Within the German sub-project CO2PR, geophysical field data (seismics and electromagnetics) will be collected during a research cruise offshore Norway currently planned for 2024. The resolution and efficiency of associated inversion techniques will be made usable for large-volume (Gt) reservoirs and complemented with new AI methods to identify signals suitable for monitoring.

The Norian Trossingen Plateosaurus bonebeds have piqued the interest of many researchers over the past 100 years. Several investigations took place in the 1910’s to 1930’s excavating over 80 skeletons, but was then left to rest until 2007. In 2007, 2008 and 2010 small excavations took place, resulting in one and a half skeleton of Plateosaurus trossingensis. The depositional environment of the site has had a controversial history with several theories, ranging from a sandy desert to a catastrophic mudflow, to a watering hole with a muddy bottom. In the summer of 2022 an exploratory investigation was performed at the Trossingen site to prepare for large scale excavation in 2023, which will incorporate stratigraphical, sedimentological and taphonomic investigations to further dive into the evolution of the environment and its relation to the fossil remains. Here we present the first results of both the 2022 and 2023 field campaigns with a revised depositional history. The preliminary investigations in 2022 already showed the section is not as homogenous as previously thought and uncovered several structures, most of which not previously recognised, such as: (1) several small channel–like deposits likely of fluvial origin and (2) a carbonate layer with a possible lacustrine origin in the lower beds, (3) large pedogenetic carbonate nodules in the middle beds, and (4) large mudcracks in the upper beds. All these features, together with preliminary taphonomic data from the bones, suggest a potential upwards aridification trend across the entire section.

description: Charged asymptotically AdS black branes in five dimensions are sometimes unstable to the condensation of charged scalar fields. For fields of infinite charge and squared mass -4 Herzog was able to analytically determine the phase transition temperature and compute the endpoint of this instability in the neighborhood of the phase transition. We generalize Herzog's construction by perturbing away from infinite charge in an expansion in inverse charge and use the solutions so obtained as input for the fluid gravity map. Our tube wise construction of patched up locally hairy black brane solutions yields a one to one map from the space of solutions of superfluid dynamics to the long wavelength solutions of the Einstein Maxwell system. We obtain explicit expressions for the metric, gauge field and scalar field dual to an arbitrary superfluid flow at first order in the derivative expansion. Our construction allows us to read off the the leading dissipative corrections to the perfect superfluid stress tensor, current and Josephson equations. A general framework for dissipative superfluid dynamics was worked out by Landau and Lifshitz for zero superfluid velocity and generalized to nonzero fluid velocity by Clark and Putterman. Our gravitational results do not fit into the 13 parameter Clark-Putterman framework. Purely within fluid dynamics we present a consistent new generalization of Clark and Putterman's equations to a set of superfluid equations parameterized by 14 dissipative parameters. The results of our gravitational calculation fit perfectly into this enlarged framework. In particular we compute all the dissipative constants for the gravitational superfluid.

Spatial and Temporal Patterns of Invasive Exotic Plant Species in Response to Timber Harvesting in a Mixed Mesophytic Forest of Eastern Kentucky
Creators: name: Rasp, Benjamin Christopher
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Abstract:
Invasive exotic species (IES) responses to silvicultural treatments eight years after timber harvesting were examined and compared to one-year post-harvest IES survey in University of Kentucky’s Robinson Forest. The temporal effects of harvesting were further compared between harvested and non-harvested watersheds. Analyses were performed to identify IES spatial distribution and determine the relationships between IES presence and disturbance effects, biological, and environmental characteristics. IES prevalence was higher in the harvested watersheds and was influenced by canopy cover, shrub cover and disturbance proximity. Ailanthus altissima and Microstegium vimineum presence in the study area has decreased over time. Comparing to the 1-yr post-harvest study which only identified direct harvesting effects (e.g. canopy cover and disturbance proximities) as significant predictors, the 8-yr post-harvest survey results suggest that while harvesting effects and disturbance proximity still play an important role, environmental characteristics have also taken precedence in predicting IES presence. Overall IES prevalence has decreased but invasive plant species richness has increased over time. Results indicate that IES eradication may not need to be conducted immediately after harvesting, and when needed, can primarily target IES hotspots where low canopy cover, proximity to disturbance, and southwest facing slopes convene on the landscape.

Year: 2023

description:
Despite the high salinity, biological processes could be used in salt caverns for methanation if suitable conditions are created. With suitable backfill materials, growth areas for the formation of biofilms could be created and the availability of sulfate could be reduced. These backfill materials can also be used in the course of cavern containment to reduce convergence.

Large scale experiments enable the simulation of cavern filling with suitable porous materials and the testing of growth material to promote biofilm formation. The aim is to develop an underground methanation reactor that also minimizes the convergence of the cavern. Therefore, it has to be tested if methanogenic archaea can survive under the given conditions.

We use an autoclave system with a volume of ca. 35 liters. Pressures of up to 100 bar and temperatures of up to 100 °C are possible. The autoclave consists of two chambers and a 2.5 m long casing in between. For safety reasons, the gas will contain 95 % N2, 4 % H2 and 1 % CO2. The bottom of the autoclave will be filled with brine and salt. As filling materials, expanded clay and construction waste are foreseen.

description: We present the internal kinematics of UCD3, the brightest known ultra-compact dwarf galaxy (UCD) in the Fornax cluster, making this the first UCD with spatially resolved spectroscopy. Our study is based on seeing-limited observations obtained with the ARGUS Integral Field Unit of the VLT/FLAMES spectrograph under excellent seeing conditions (0.5 - 0.67 arcsec FWHM). The velocity field of UCD3 shows the signature of weak rotation, comparable to that found in massive globular clusters. Its velocity dispersion profile is fully consistent with an isotropic velocity distribution and the assumption that mass follows the light distribution obtained from Hubble Space Telescope imaging. In particular, there is no evidence for the presence of an extended dark matter halo contributing a significant (>~33 per cent within R < 200 pc) mass fraction, nor for a central black hole more massive than ~5 per cent of the UCD's mass. While this result does not exclude a galaxian origin for UCD3, we conclude that its internal kinematics are fully consistent with it being a massive star cluster.

description:
For more than a decade, there is an increasing international demand for free and open access to publicly funded scientific research products. These include “classical” text manuscripts, data and software underlying scholarly publications, raw and curated observational data, and many more. Essential for the long-term preservation and re-use of these scientific datasets is the storage in appropriate, ideally domain specific repositories, accompanied by comprehensive data description and sufficient metadata for data discovery. These should include a licence for data re-use and sharing. Scientific datasets should be published using citable Digital Object Identifier (DOI).

GFZ Data Services is a repository for research data and scientific software across the Earth System Sciences, hosted at GFZ. The curated data are archived, persistently accessible and published with DOI. They range from large dynamic datasets from global monitoring networks with real-time acquisition, to international services in geodesy and geophysics, to the full suite of small and highly heterogeneous datasets collected by individual researchers or small teams ("long-tail data"). In addition to the DOI registration and data archiving itself, GFZ Data Services team offers comprehensive consultation by domain scientists and IT specialists.

This presentation will introduce to the broad service portfolio of GFZ Data Services, including project-specific DOI landing pages for our national and international partners, data curation practices, supporting tools like the online metadata editor, data description templates and extensive data publication guidelines. It will further show examples of how metadata exchange with other data portals is increasing the visibility of our data publications.

The interaction of a vertical applied field and the piezoelectric fields of the ring with strongly-correlated excitonic complexes switches excitons between two different lateral locations within the ring. This control should be observable through polarizability and dipole measurements, and, for biexcitons, an energy shift beyond the normal Stark shift.

description:
The Rhenish Slate Mountains are one of the classical outcrop areas for stratigraphic research in Devonian and Carboniferous strata. Lithostratigraphic mapping of German parts of the Rhenish Slate Mountains has been performed systematically for over 100 years starting with a mapping campaign implemented by the Prussian Geological Survey in the 1920s. Today, geological mapping is performed by the Geological Survey of North Rhine-Westphalia and published in an output scale of 1 : 50 000. Results are made available via a modern geodata infrastructure for the use by digital map display. We present sedimentological facies models for the time spans of the Middle to Upper Devonian and the Mississippian. On the one hand the lithostratigraphic lexicon LithoLex is the data source of definitions of lithostratigraphic units and on the other hand results of field mapping are needed to classify lithostratigraphic units that are not yet implemented in the lexicon. Our models can work as links between results of field mapping of the northern Rhenish Slate Mountains east of the river Rhine and help to classify lithostratigraphic units, where it is still needful.

description: The NHGRI-EBI GWAS Catalog is a comprehensive and widely-used database of published genome-wide association studies (GWAS), providing links between genetic loci and complex traits. As of December 2018, the Catalog contains over 3,600 publications and 81,000 unique SNP-trait associations. The increasing complexity of GWAS publications in recent years presents challenges for the accurate and user-friendly display of Catalog data. To meet this challenge, we engaged with the GWAS community to develop a new user interface, released in September 2018. We analysed the most common search terms and conducted user interviews to define and prioritise improvements. We also published a “labs” site for users to test proposed features and conducted face-to-face user testing throughout the development process. Following release, we sought feedback and continued to make incremental changes in response to users’ needs.

The new interface enables more specific and intuitive access to Catalog data. Individual pages for each publication, study, trait, variant and gene, allow us to make available information tailored to each of these key concepts. Each page includes supporting information to provide context, a table of associations and links to external resources. New visualisations support further analyses of Catalog data. A plot of the linkage disequilibrium landscape allows users to investigate a region of association tagged by a GWAS variant and prioritise causal variants. Users can also visualise associations across the genome by trait in a LocusZoom plot. The GWAS Catalog now hosts full p-value summary statistics in addition to curated associations. Access to summary statistics is now integrated within the user interface, providing users with direct links to available files, in addition to API access.

These changes respond to developments in the GWAS field as well as user feedback and will ensure that the GWAS Catalog continues to be a valuable resource for the scientific community.
title: Geoethics and Transgenerational Climate Crimes - four examples to hold States and corporations accountable

Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)

description:

Is it possible to hold States and corporations accountable for the extractive industry’s transgenerational climate crimes? Answering this question implies the definition of climate crimes in time and space and, for this reason, four case studies will be analyzed to substantiate the critical analysis proposed: the Coalbrook mine disaster in South Africa (1960), the Amoco Cadiz oil spill in France (1978), the Performance Coal Company explosion in the United States (2010), and the Vale-BHP tailing dam collapse in Brazil (2015). Actions that cause climate catastrophe affect individuals and ecosystems beyond jurisdictions in an uncontrolled and incalculable way. The real purpose of the extractive industry must be observed from a geoethical perspective, that is, the extractive industry’s capacity of producing and reproducing life. States and corporations have historically managed the extractive industrial complex regardless and to the detriment of the existence of life in explored territories. This means that States and corporations are accomplices in actions that not only cause the worsening of life conditions in the present time, but also prevent life on the planet to be fostered and preserved. By comparing the alleged benefits and the real harm arising from a geopolitical developmental agenda of global endless industrial extractivism, this paper develops the geoethical possibilities of definition of transgenerational climate crimes departing from four case scenarios and their devastating consequences.
Episodic star formation in the Upper Scorpius association traced by its kinematics

description: Stellar associations can be discerned as over-densities of sources not only in the physical space but also, more importantly, in the velocity space. The common motion of their members, gradually eroded by the galactic tidal field, is partially reminiscent of the initial kinematic structure. Using recent data from Gaia EDR3, combined with radial velocities from GALAH and APOGEE, we traced back the present positions of stars belonging to Upper Scorpius, a subgroup of the Scorpius-Centaurus association. A significant part of these stars (the "clustered" population) appears composed of many smaller entities, which were in a more compact configuration in the past. The presence of a kinematic duality is reflected into an age spread between this younger clustered population and an older diffuse population, in turn confirmed by a different fraction of disc-bearing stars. Star formation in the region appears to have lasted more than 10 Myr and to have proceeded in small groups that, after a few Myr, dissolve in the field of the older population but retain for some time memory of their initial structure. The consequences of our results will be discussed here, and a comparison with stellar ages inferred through isochrone fitting will shed light on the timescale of gas removal.

description:
Iron oxide and hydroxide minerals are widespread in many aquatic environments and as such, can determine the fate of several metals of concern. Their role on metal mobility is generally studied under controlled conditions using synthetized materials. However, natural systems are complex and present a wide range of conditions, which may release metals differently to laboratory settings. In this study, we aim at understanding the mobility of geogenic, technology critical elements such as vanadium, nickel, cobalt, niobium, and tantalum from black sand sediments. These sediments from the OIB volcanic environment of the Canary Islands are the product of weathering and erosion of relatively geologically recent, ultramafic volcanic rocks composed of basanitic, phonolitic, nephelinitic and, locally, melilitic lavas and tuffs, sources of mafic heavy minerals deposited as a placer. The sediments were extracted through magnetic separation, characterized via XRD and SEM-EDS techniques, and further processed with a series of parallel selective extractions following widely applied protocols. Desorption kinetics during the extraction procedures were also investigated in order to understand the efficiency of the protocol for such sediments. Total element concentrations were quantified via XRF and LA-ICP-MS, whereas dissolved concentrations were determined via ICP-MS. Our results point towards contrasting selectivity during the extractions and different iron oxide mineral fractions in which these metals are bound. This information has a broad application for the potential environmental risk of metal mobility in aquatic systems.

description: This In Brief argues initiatives aimed at improving women’s political representation in the Pacific must be informed by the emerging evidence concerning the performance of individual women candidates. They must move beyond diagnostics that attribute women’s poor performance at the polls to culture, custom or the lack of a level playing field and seek instead to learn from the experiences of women who are elected, and those who poll strongly but fall shy of being elected.

description: We present deep radio continuum observations of the cores identified as deeply embedded young stellar objects in the Perseus molecular cloud by the Spitzer c2d programme at a wavelength of 1.8 cm with the Arcminute Microkelvin Imager Large Array (AMI-LA). We detect 72% of Class 0 objects from this sample and 31% of Class I objects. No starless cores are detected. We use the flux densities measured from these data to improve constraints on the correlations between radio luminosity and bolometric luminosity, infrared luminosity and, where measured, outflow force. We discuss the differing behaviour of these objects as a function of protostellar class and investigate the differences in radio emission as a function of core mass. Two of four possible very low luminosity objects (VeLLOs) are detected at 1.8 cm.

title: Description of scientific metadata at the Federal Waterways Engineering and Research Institute (BAW)

description:
The Federal Waterways Engineering and Research Institute acts as a consultant for and supports the Federal Ministry of Digital and Transport (BMDV) and the Federal Waterways and Shipping Administration (WSV) in navigation-related water engineering tasks. It creates and uses large volumes of scientific data like digital elevation models, simulation results, monitoring data, etc. as part of these activities. The description of this data with metadata is an essential prerequisite for its long-term storage, publication, retrieval and reuse. The requirements for metadata management were implemented with the INGRID software. INGRID offers various interfaces for capturing and processing metadata. It behaves format-agnostic, so different metadata formats can be processed.

The requirements for metadata processing at BAW are quite extensive and differ from the possibilities of usual geodata portals. As a result, custom fields and data classes have been defined in the metadata model. The ISO19139 metadata is used for transferring metadata to external geodata portals. A DOI data record can be generated from the metadata, which can in perspective also be registered automatically at datacite.org. To ensure the description of simulation results with metadata, the delivery of metadata together with data is firmly established in the workflows for data archival and publication.

The presentation describes the requirements for metadata processing, the basic structure of the application, and discusses the life cycle of metadata.
