description:
The Mesozoic to Cenozoic intraplate to rift-related magmatic activity in central Europe spawned both, intrusive and extrusive carbonatites. Located within the intersection of the Regensburg-Leipzig and Gera-Jachýmov fault zones, the eroded diatreme of Ebersbrunn provides a unique opportunity for mineralogical and petrographic investigations to explore the magma genesis and its lithospheric evolution. Electron microprobe analyses on several mineral phases were acquired to obtain thermobarometric estimations and unravel the internal textures. Moreover, detailed microscopic studies on juvenile fragments are used for the characterization of volcanic facies. Here, the compositional variation in amphibole (with Mg# from 0.804 to 0.932) and mica (Al-rich phlogopite and eastonite) can be linked to the presence of lamproite components in the generation of supplying magma system and show a multi-episodic crystallization history. Thermometric estimations for the carbonatitic magma showed a wide range from 450 to 672°C (obtained on low- and high-Mg calcite and dolomite). The joint presence on high-T amphibole (872 to 965 °C) and mica ( ca. 950 °C) suggests the contemporaneous crystallization from a single magma storage and the presence of mid-crustal magma storage at 15 to 21 km.

The petrographical studies on circular/ ellipsoidal juvenile fragments revealed different populations of peletal lapillis, with either dry or wet silicate, Fe-Ti-oxide, and/or carbonate phases in the kernel and a carbonatitic and/or silicic shell composition. This indicates the influence of hybrid magma and emphasizes the multi-stage layering process. The oriented prolate-shaped apatite crystals at the rim of pelletal lapillies are addressed to turbulent motion during magma ascent.

description:
The late Paleocene and early Eocene climate was punctuated by several warming events known as hyperthermals. These events reflect perturbations in the carbon cycle, identified by the negative carbon isotope excursions, including the prominent Paleocene-Eocene Thermal Maximum. Under the high carbon emission scenario of RCP8.5, the climate is predicted to most closely resemble early Eocene conditions within the next hundred years, making it a promising analog to study the possible long-term environmental changes that we have to face in the near future. High-resolution geochemical records from the Atlantic and Pacific provide astronomically calibrated age models of the early Paleogene. However, these sites are located in the equatorial- to subequatorial regions, so the high-latitude climate changes of the early Paleogene still remain elusive. IODP Expedition 378 recovered new Paleogene sediments at Site U1553 in the high-latitude Southwest Pacific.

Here, we present a novel late Paleocene to early Eocene age model spanning ~7 million years, which will be essential for future paleoceanographic studies of this site. To construct the age model, we used a combined chemostratigraphic and biostratigraphic approach. Our results show that the shape and pattern of the U1553 bulk sediment δ13C record generally match the orbitally-tuned records, which is reflective of a global trend. However, the nannofossil events at site U1553 exhibit a striking delay compared to lower latitude sites, suggesting that these commonly-used datums are not applicable at the high latitudes.

Geoparks serve as an important link between science and the public. Through the lens of geotourism, they not only strengthen regional development and sustainable economics but also offer an interesting encounter with geology and the profound story of our planet’s past. Geoparks provide universal access to the habitat Earth and thereby enhance the respect for nature within society. Since last year the Geopark Ries has been labeled UNESCO Global Geopark, highlighting its remarkable geological heritage on the global stage. The concept of the Geopark Ries is designed to captivate, interest and educate individuals from diverse backgrounds. Even from a very young age, visitors are able to dive into Earth’s history via child-firendly educational programs. Numerous geosites, expert-led tours and thematic hiking trails not only deepen the understanding for the environment and geology of interested locals and tourists but also grant researches and students access to the type locality of Suevite and Riesite.

Therefore, Geoparks play a significant role in raising public awareness regarding the relationship between geology, nature and humanity, thus laying a solid foundation for a sustainable future.
The targum (1966:Mar. 01 - 1966:Mar. 31)
Creators: name: No Name Supplied

Year: 1966

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Contribution of muscle-tendon mechanics to force control
Creators: name: Smart, Rowan Roylance
Publisher: name: University of British Columbia
Year: 2023

description: The overall goal of this dissertation is to evaluate contributions of muscle and tendon behavior to isometric force control and balance tasks. This was undertaken in populations that have well-established differences in muscle-tendon mechanics, force steadiness (FS), and balance. The specific objectives of this dissertation were as follows: 1) Determine if using resting tendon cross-section area (CSA) underestimates tendon stress compared to using CSA measured during contraction in the calculation, 2) Assess the contribution of muscle-tendon mechanics to population-based differences in FS, and 3) Examine intermuscular coherence during standing balance in a population with reduced balance. Study #1 addressed objective 1 by demonstrating that tendon stress values of the distal biceps brachii (BB) tendon are significantly greater when using measures of CSA obtained during contraction compared to at rest, and that the differential increase between methods in calculated stress values is both sex- and age-dependent. Study #2 addressed objective 2 by examining contributions of distal BB tendon mechanics to isometric elbow flexion FS in young males and females, and showed that greater strength and tendon stress in males facilitates the production of steadier elbow flexion compared to females. Study #3 also addressed objective 2 and demonstrated that lower strength in older adults with Parkinson’s disease (PD) contributes to reduced plantar flexion FS compared to age- and sex-matched healthy older adults, and that reduced medial gastrocnemius fascicle shortening and Achilles tendon elongation in PD may also be a contributing factor. Study #4 addressed objective 3 by evaluating intermuscular coherence of the plantar flexors along with center of pressure (CoP) parameters during standing balance in older adults with PD and age- and sex-matched healthy older adults. Older adults with PD had marginal increases in CoP parameters, but intermuscular coherence did not differ between groups, suggesting that lower-leg intermuscular coherence is not a contributing factor to increased sway in high-functioning older adults with PD. This dissertation provides new insight as to the contribution of muscle-tendon mechanics and muscle coordination to functional force control through sex-, age- and disease-based population comparatives, and demonstrates the importance of tendon mechanics in producing steady contractions.

description:
Material flow data are generally used to assess the environmental footprint of economic activities, e.g. through life cycle assessments (LCAs). This is particularly relevant for the resource-intensive sector of primary raw material extraction and the associated raw material supply chains. As LCAs are firmly established in industry, research, and governmental organizations to support decision-making, e.g. for comparing the environmental impact between recycling processes and primary raw material extraction, an up-to-date and transparent database is the basis for meaningful results. However, the ecological parameters for primary raw material extraction up to refining in the databases often do not reflect the current status. In addition, the data for many metals are often only aggregated values and not available for individual process steps of mining, processing, smelting and refining.

To address this challenge, we conducted a comprehensive survey of emissions data and other project- or deposit-specific data on copper mining, smelting and refining, and correlated the results with currently available general sector data. The data collection was carried out, on the one hand, through a customized questionnaire completed by the companies participating in the studies and, on the other hand, through literature research. The newly acquired project-specific knowledge enables improved calculation of the carbon footprint and greenhouse gas emissions of representative mining projects and smelters/refineries. Furthermore, it serves for a direct analysis of the calculation bases for life cycle assessments and the data on CO2 emissions of other data providers and their evaluation.

description:
The formation of crystallographic preferred orientations (CPO/texture) in sediments is often attributed to rigid grain rotation of minerals and aggregates, plastic-brittle deformation and dissolution-precipitation processes. Especially, clay minerals have a large shape anisotropy due to their platy habit. Here, we present an experimental approach in order to quantitatively explore the influence of particle settling and subsequent compaction in an undisturbed, ideal environment.

A powder of idiomorphic kaolinite grains was mixed with a fine-ground, illite aggregates in mass proportions of 0, 30, 50, 70 and 100 % in artificial seawater. The sludges settled in 80 cm high tubes. For each composition three samples were produced: Sedimentation-only and two drained compaction experiments (30 and 60 vol-%), which were carried out in a mechanical press with uniaxial load up to 0.4 MPa and 4 - 8 MPa. The CPO of clay minerals was measured using high energy X-ray diffraction at beamline P07b at Deutsches Elektronen-Synchrotron (DESY) and pole figure data was directly extracted using single peak evaluation.

The results indicate that sedimentation alone, can yield a strong texture of the clay minerals. The increase in texture strength (TS) is decreased at higher applied loads. TS is linearly related to shortening and porosity reduction. The kaolinite TS is inversely correlated with texture-inhibiting illite aggregate content which hampers further particle rotation. It is interpreted that the initial stages of settling and early rigid body rotation during compaction are thus the most important processes in the formation of a CPO in clay rich sediments.

description: Popular Scientific Summary -- The atmosphere of the Sun is envisioned as composed of inherently complex, non-homogeneous, and dynamic layers. A detailed understanding of the physical processes involved in these layers is still lacking. For example, it is largely unknown why the outermost layer of the Sun’s atmosphere (corona) is so much hotter than the photosphere by millions of degrees. Astrophysicists think that the layer sandwiched between the photosphere and the corona, known as the interface region, may hold the key to a better understanding of the nature of this controversy. With the help of coordinated high-resolution ground and space-based observations from the Swedish 1-m Solar Telescope (SST) on La Palma, Spain, and NASA’s Interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO), I aim to unlock some of the mysteries surrounding the dynamics of the interface region with a focus on small-scale jets, known as “spicules”. Spicules are found almost everywhere on the Sun’s surface and at any given moment there can be as many as 10 million of them rapidly shooting outwards. Because of their “omnipresence”, it is suggested that they play a major role in energizing the outer atmospheric layers of the Sun. This thesis focuses on their physical characteristics, dynamics, and their role in the mass-balance and heating of the solar atmosphere.

description: Varieties of Sums of Powers describe the additive decompositions of an homogeneous polynomial into powers of linear forms. Despite their long history, going back to Sylvester and Hilbert, few of them are known for special degrees and number of variables. In this paper we aim to understand a general birational behaviour of VSP, if any. To do this we birationally embed these varieties into Grassmannians and prove the rationality, unirationality or rational connectedness of many of those in arbitrary degrees and number of variables.

title: Legally recognising intention : parenthood in surrogacy and assisted conception
Creators: name: Horsey, Kirsty
Publisher: name: University of Kent
Year: 2023

description: Since its emergence in the late 1970s, surrogacy has been both socially and legally problematic. However, it can be argued that there has been an evolution of opinion regarding the practice of surrogacy, on both a cultural and a professional level. Many of the problems predicted by academic and other commentators have not occurred or, if they have, they are not widespread: surrogacy is not, on a general level, exploitative; neither does it commodify children or the reproductive process. It does, however, provide a reproductive option of last resort for some people or couples experiencing infertility or involuntary childlessness. As such, and because no danger is presented purely by allowing the practice of surrogacy to continue, it must be facilitated and legitimated as a reproductive option. Furthermore, because it is used as a method of founding a family, those who play the familial roles should be recognised, in order to make the social reality of motherhood and fatherhood a legal reality. Current regulation allows but discourages the operation of surrogacy. This thesis questions whether this should be the case and, in concluding that it should not, suggests ways in which surrogacy could be regulated in the future. The essence of these recommendations is that the intending parents in a surrogacy arrangement should be legally recognised as the parents of the child born to the surrogate. This thesis will argue that this recognition should be based on the concept of intention and supported by the enforcement of surrogacy arrangements as contracts.

description: A major controversy has arisen in QCD as to how to split the total angular momentum into separate quark and gluon contributions, and as to whether the gluon angular momentum can itself be split, in a gauge invariant way, into a spin and orbital part. Several authors have proposed various answers to these questions and offered a variety of different expressions for the relevant operators. I argue that none of these is acceptable and suggest that the canonical expression for the momentum and angular momentum operators is the correct and physically meaningful one. It is then an inescapable fact that the gluon angular momentum operator cannot, in general, be split in a gauge invariant way into a spin and orbital part. However, the projection of the gluon spin onto its direction of motion i.e. its helicity is gauge invariant and is measured in deep inelastic scattering on nucleons. The Ji sum rule, relating the quark angular momentum to generalized parton distributions, though not based on the canonical operators, is shown to be correct, if interpreted with due care. I also draw attention to several interesting aspects of QED and QCD, which, to the best of my knowledge, are not commented upon in the standard textbooks on Field Theory.

description:
Analytical challenges such as low concentrations and a saline matrix, contamination risks during sampling and analysis, and the accessibility of remote ocean areas limit available methodologies for the investigation of trace elements in the open ocean and call for innovative, easy to use and robust investigation tools. Furthermore, the application of methodologies for the monitoring of e.g., deep-sea mining activities as part of environmental impact assessments will become of increasing importance for future marine research. We here evaluate an in situ passive sampling method using the technique of diffusive gradients in thin films (DGT), focussing on Mn, Cu, Ni, V, Cd, As, Sb, and rare earth elements and yttrium. Sampling was performed in bottom seawater above the BGR contract area for polymetallic nodule exploration in the Clarion Clipperton Zone in the NE Pacific. We present data from different passive sampling setups at depths between 0.3 m and 550 m above the seafloor accumulating trace metals for periods of 3 days up to 2 years, and discuss the effects of deployment time and the binding membrane type. Derived concentrations represent the labile fraction of the metals and hence that fraction that is (bio)available for an uptake through cell membranes. Results are compared to point sampling of seawater providing trace metal concentrations for different size fractions, which allows to constrain the degree of lability of dissolved trace metals. We further present results from the monitoring of a collector mining test of polymetallic nodules with respect to trace metal mobilization at the seafloor.

description: Particle detectors that use liquid xenon (LXe) as detection medium are among the leading technologies in the search for dark matter weakly interacting massive particles (WIMPs). A key enabling element has been the low-energy detection threshold for recoiling nuclei produced by the interaction of WIMPs in LXe targets. In these detectors, the nuclear recoil energy scale is based on the LXe scintillation signal and thus requires knowledge of the relative scintillation efficiency of nuclear recoils, Leff. The uncertainty in Leff at low energies is the largest systematic uncertainty in the reported results from LXe WIMP searches at low masses. In the context of the XENON Dark Matter project, a new LXe scintillation detector has been designed and built specifically for the measurement of Leff at low energies, with an emphasis on maximizing the scintillation light detection efficiency to obtain the lowest possible energy threshold. We report new measurements of Leff at low energies performed with this detector. Our results suggest a Leff which slowly decreases with energy, from 0.144 +/- 0.009 at 15 keV down to 0.088 +0.014 -0.015 at 3 keV.

description:
Plutonic xenoliths in volcaniclastic rocks from the Laacher See (LS), East Eifel and the Rockeskyller Kopf Volcanic Complex (RKVC), West Eifel, were studied. They show different ways of magmatic carbonate formation at plutonic levels.

Well-preserved original igneous textures of carbonate-bearing syenites were observed in LS plutonic xenoliths. Calcite is often crystallised in “micropegmatitic texture” with sanidine and nosean. These structures argue for syngenetic crystallisation of calcite and main silicate minerals in alkali syenite melts in the case of the LS volcano. Different proportions of euhedral calcite and silicate minerals point to calcite cumulate formation.

Occurrence of calcite associated to apatite, magnetite, phlogopite and pyrochlore in nosean syenite from xenoliths of the RKVC is in line with the assumption of magmatic carbonate formation in a highly fractionated undersaturated silicate magma.

Next to carbonatite - nosean syenite xenoliths and sanidinite, a series of different mafic xenoliths were found around the RKVC, from amphibolite to pyroxenite and magnetite cumulates, that could indicate one or more magma chambers below the volcano.

A comprehensive data set for geochemistry, mineralogy and mineral chemistry of the carbonates of LS and RKVC volcanoes is provided. Characteristic carbonate and whole rock trace element patterns are presented. Different chondrite normalised REE signatures of RKVC and LS argue for different ways of fractionation in these volcanic systems.

description:
The lithium isotopic composition (δ7Li) of marine carbonates is known as a proxy for the chemical weathering intensity of silicate rocks. To evaluate the role of weathering as a sink for atmospheric CO2 during the Late Cretaceous, we generated a 20 Ma δ7Li record (86.3–66.0 Ma) using chalk from Northern Germany as an archive. The late Santonian to Maastrichtian record shows an overall increase of ~4.5‰ with superimposed increases in the late Santonian, early Campanian and across the Campanian–Maastrichtian transition.

The overall increase in δ7Li fits with the Late Cretaceous increase in seawater 87Sr/86Sr. Further, the δ7Li record strongly resembles both the evolution of deep-sea temperatures based on benthic oxygen isotopes and modeled changes in the rate of seafloor spreading. Thereby, increases of δ7Li in the early Campanian and across the Campanian–Maastrichtian transition correspond to major sea level falls, and the latter with a negative δ13C excursion.

These coherences allow three interpretative approaches: (1) Climate cooling controlled the weathering congruency and the magnitude of Li isotope fractionation by clay mineral formation on the continents. (2) Lowland exposure promoted erosion together with enhanced soil and clay formation after sea level falls. (3) A temperature-dependent fractionation during low-temperature basalt alteration affected the seawater δ7Li signal in a time, when more fresh oceanic basalts where available due to higher spreading rates. The best possible interpretation for the Late Cretaceous δ7Li record and the often-neglected aspects of basalt alteration and reverse weathering need to be further assessed and discussed.

In the frame of the SAMUH2 project water samples were taken at a geological pore gas storage. In the course of the abandonment of a natural gas storage, deep fluids could be recovered from a depth of 500 - 600 meters. A total of eight boreholes were sampled from injection and observation wells. The focus of the investigations was on the analysis of the chemical composition of the fluids as well as the characterization of the microbial biocoenosis and partly also their metabolic activity.

Organic acids were detected in varying concentrations and compositions in both the fluid samples taken at the injection and observation wells. Organic acid concentrations ranged from 0.1 to 730 mg/L.  Gen copies of Bacteria, sulfate reducers (SRB) and methanogenic archaea were detected in all fluids by qPCR. A detailed characterization of the microbial community was carried out by microbiome analysis. A diverse microbial community was detected on fermenters and methanogenic archea. Sulfate reducers, on the other hand, were identified predominantly in the observation wells.

Several laboratory experiments demonstrated that the fluids of injection wells contained an active biocenosis capable of hydrogenotrophic methanogenesis. In contrast, only one observation well fluid demonstrated the activity of hydrogenotrophic methanogenic archaea. The capability of underground storage facilities for producing eco- ("green") methane is a further topic of this study.

The Geological Archives (geoarchives) of State Geological Surveys have an over 150 years old tradition. Since the first geological surveys were funded in the early 1870s State Geological Surveys collected, inventoried and provided samples, maps and reports from geoscientific exploration and analysis. As a result, geoarchives comprise a huge store of knowledge for geologic surveying and further applied questions. Thereby, work tasks in geoarchives have special focusses: (1) In contrast to classical steady-state archives, the inventory must be permanently available and usable for geological surveys and economic companies. (2) All inventory can accurately be georeferenced, i.e. even documents must be assumed to contain geoinformation. (3) Geoarchives contain material, e.g. rock samples, drill cores on the one hand and printed reports, maps and paper rolls on the other hand, with a broad spectrum of requirements on the storage conditions. With the commencement of the Geological Data Act (GeolDG) these tasks were recently expanded to aspects of digitalization and digital provision of geoarchive inventory. Therefore, all material must be completely checked, categorized and indexed with keywords to make the inventory FAIR (findable, accessible, interoperable and reusable). In our contribution we present the historical evolution and relevance of the geoarchive of the Landesamt für Geologie und Bergwesen Sachsen-Anhalt (LAGB) and explain our recent concepts against the background of the GeolDG.

Recent advances in technological applications to deliver aphasia therapy also provide a unique opportunity to measure large data sets of patient reported outcomes on individuals’ ability to participate in and perform functional activities of daily living. Our ongoing efforts at Constant Therapy involve developing a self-reported outcome measure of communication and participation across domains that include expression, comprehension, reading, writing and problem solving. An initial 18 question survey developed as a 5 point likert scale was administered to 330 individuals with stroke/aphasia. Questions included “How well can you write a letter or email?”; “Are you able to do things that you like to do?” and “How well can you follow other peoples’ conversation?” and initial results showed that several of these questions elicited skewed responses. For example, for the question, “How well can you write a simple message?” 0% said "Not Well", 19% said "Less well", 24% said "Moderately Well", 30% said "Normally", and 27% "Very Well". After subsequent iterations, some questions were modified to elicit more quantitative information.  Thus, when asked the question, “How many written notes or messages did you write last week (e.g. to-do lists, reminder notes, e-mail)?”, of the 2197 individuals with stroke/aphasia who responded to this question, 39% said 0-3; 27% said 4-7, 15% said 8-11, 9% said 12-15 and 10% said 16 or more, thus providing a wider range of responses. While this work is ongoing, it highlights that (a) patients can accurately self-report their communication activities on a software program and (b) that the variation in responses provides an important baseline to evaluate changes in functional/social communication after rehabilitation.

description: This report constitutes SSHOC Deliverable 9.10, which describes the first stage of testing of the Knowledge Graph (KG) for Electoral Studies that constituted Deliverable D9.9 (‘Delivery of user-validated Knowledge Graph, and Election Studies Analytics dashboard’). This report also links up closely with the reports of Deliverables D9.6 (‘Demarcation Report of Electoral Studies User Community’), Deliverable 9.7 (‘Design and Planning of Knowledge Graph in Electoral Studies’), and Deliverable D9.8 (‘User Community Involvement in the Development of a Knowledge Graph for Electoral Studies’). The first stage of testing of the KG involved a small group of testers and focussed in particular on the intelligibility and functionality of the user interface (UI) of the KG. This aspect is seen as an absolute precondition for productive further testing among wider groups of end-users and focusing on other aspects of the KG. The outcome of this stage of testing was the identification of issues that hampered the user-specification of searches and user-manipulation of search results. These experiences were fed back to the team responsible for programming the KG, which resulted in an upgraded version which will be subjected to further end-user testing and try-outs.

description: We test third-order standard perturbation theory (SPT) as an approximation to non-linear cosmological structure formation. A novel approach is used to numerically calculate the three-dimensional dark matter density field using SPT from the initial conditions of two high-resolution cosmological simulations. The calculated density field is compared to the non-linear dark matter field of the simulations both point-by-point and statistically. For smoothing scales above 8 Mpc/h it shows a good agreement up to redshift 0. We present a simple fitting formula to relate the linear and non-linear density contrast that accurately recovers the non-linear time evolution for 0 <= z <= 10 at the per cent level. To address the problem of biasing between the matter field and the haloes identified in the simulation, we employ the Eulerian local bias model (ELB), including non-linear bias up to the third order. The bias parameters are obtained by fitting a scatter plot of halo and matter density (both from the simulation and from SPT). Using these bias parameters, we can reconstruct the halo density field. We find that this reconstruction is not able to capture all the details of the halo distribution. We investigate how well the large scale bias can be described by a constant and if it corresponds to the linear bias parameter b_1 of the local bias model. We also discuss how well the halo-halo power spectrum and the halo-mass cross spectrum from the reconstructed halo density field agree with the corresponding statistics from the simulation. The results show that while SPT is an excellent approximation for the matter field for suitably large smoothing scales even at redshift 0, the ELB model can only account for some of the properties of the halo density field.

description:
Germany has a long history in metal ore mining stretching over a period of more than 1000 years. Both small and large heaps or dumps remain in the mining districts typically without any safety measures (coverage, monitoring etc.). Often these sites are still a considerable point source for pollutants like metals, metalloids or processing chemicals. However, extraction technologies have been much less effective in the past and for certain elements (e.g. Ge) no technical application has been known. As such, mine waste including historic waste or ore dumps and tailings may represent a considerable and easily extractable future resource especially for technology critical elements.

We investigate the mineralogy, geochemistry and leaching behaviour of different types of mine residues in former mining districts of the Black Forest, Wiesloch and the Donnersberg area. With respect to the critical raw materials Ge, Sb, barite and fluorite, several of the investigated mine waste seem to be of potential economic interest. But elements like Pb, Zn (both in the wt% range) or Ag (>100 mg/kg) are also promising with regard to reprocessing in some of the investigated districts. From an environmental point of view, Pb, Zn, As, Cd, Sb und Tl are of concern regarding their concentration and leachability. Both, the content and potential mobility largely depend on the ore type, the period of extraction and the processing technique applied. We think that extracting raw materials from mine residues has the advantage of gaining metals locally and giving back space to nature and society at the same time.

description:
Geochemical data are pervasively acquired in the Earth, environmental, and planetary sciences, as they offer unique evidence for past and present processes in the natural world that advance scientific knowledge and enable solutions of societal relevance. But geochemical data today are difficult to reuse because of the heterogeneous and fragmented nature of the geochemical data landscape with incompatible data structures, inconsistent metadata, and disconnected databases. As new, data-driven and often interdisciplinary research approaches are rapidly expanding that promise to empower the next generation of scientific discoveries, the urgency for a new ecosystem of interoperable, machine-readable geochemical data is eminent. OneGeochemistry is an international initiative to promote data standards in geochemistry and advance a global network of geochemical data resources. OneGeochemistry has been pursuing a diverse array of strategic activities: engagement with data repositories, professional societies, science unions and associations, publishers and editors, funding agencies, government agencies, instrument manufacturers, and researchers; participation in the WorldFAIR project (https://worldfair-project.eu); providing open access to existing standards or best practices; and establishing an international governance for the initiative.  The geochemical databases GEOROC, EarthChem, the Astromaterials Data System, and MetBase that participate in the OneGeochemistry initiative, are actively cooperating to harmonize their data models and create FAIR vocabularies for metadata that will enable interoperability between the systems and can be adopted more broadly. This presentation will provide an update on the status of activities and outcomes that pertain to technical and policy aspects of geochemical data standards.

description: We consider the Dirac equation in 3+1 dimensions with spherical symmetry and coupling to 1/r singular vector potential. An approximate analytic solution for all angular momenta is obtained. The approximation is made for the 1/r orbital term in the Dirac equation itself not for the traditional and more singular 1/r^2 term in the resulting second order differential equation. Consequently, the validity of the solution is for a wider energy spectrum. As examples, we consider the Hulthen and Eckart potentials.

description: This study examined whether partner reauditorization affected the attitudes reported by young adults toward a child who communicated using nonelectronic AAC. The study also examined preferences for the way the AAC system was used (i.e., in the presence or absence of reauditorization), whether reauditorization was associated with differences in perceptions about the social interactions with the child, and ease of understanding the child’s aided messages. For the study, 84 young adults viewed (a) one video of a child who communicated using nonelectronic AAC in which the child’s communication partner reauditorized the child’s aided message, and (b) a second video in which the message was not reauditorized. Participants answered survey questions designed to measure dependent variables including attitudes, ease of understanding, perceptions about the child’s social interactions, and preferences regarding reauditorization. Attitudes toward the child were more positive when reauditorization was implemented. Partner reauditorization may play a role in improving attitudes that individuals hold about a child who uses nonelectronic AAC and may also contribute to the ease of understanding an aided message.
