description:
New developments of energy-efficient recycling processes and systems for LIB recycling are required from the perspective of resource circulation, raw material supply and sustainability. One promising approach is based on a combined pyro- and hydrometallurgical treatment. However, tailoring respective slag compositions and processing conditions is a challenging task in terms of increasing recycling efficiency. It requires a fundamental understanding of the phase development in the slag. For this, thermodynamic data and models are needed to predict phase formation and fractions under certain compositions and solidification conditions. The influence of manganese in LIB slag systems is not fully understood. An important base system is the Li2O-MnO system, for which no thermodynamic model-compared data are available in the literature that are in a composition range relevant for LIB slags. In this work, the Li2O-MnO system is studied thermodynamically. Different compositions of Li2O-MnO in a LIB relevant slag composition field are synthesized and investigated with respect to their caloric and thermal properties with STA measurements under respective solidification conditions, such that solid-liquid transitions, as well as specific heat capacities of the mixtures, are obtained. Based on the experimental data gained in this study, model parameters of the modified quasichemical model (MQM) are optimized in the CALPHAD framework, such that the liquid phase of this system can be modelled thermodynamically for several compositions. This first survey contributes to a deeper understanding of the influence of manganese on the phase formation during solidification in lithium-containing systems.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Project crashing algorithm selection of a project is a crucial aspect of each project to decision makers striving to expedite or crash a project. In this study a new method has been introduced to choose alternatives based on the interest and preferences of decision makers due to the uncertainties of the optimal solutions of crashing algorithms. A multi criteria decision making (MCDM) technique, The Technique for Order of Preference using Similarity to Ideal Solution (TOPSIS) is used to select the appropriate crashing algorithm. The proposed method leads the decision makers to select the desirable algorithm to their projects. An example is analysed to demonstrate the capabilities of the present method.
title: Earth’s mantle: probing a hidden heavy-weight

description:
Earth’s mantle comprises the vast region between the crust and core, some 84% by volume and 67% by mass – a real heavyweight. The superposition of key events – all ultimately rooted in the mantle – conditioned the evolution of the whole Earth system that produced our hospitable and resource-rich, yet fragile habitat. These include magma ocean crystallisation during Earth’s tumultuous beginnings, the formation of first atmospheres and oceans, the emplacement and emergence of weatherable crust, the transition to plate tectonics, and volcanism at and away from plate margins that continues today.

The mantle is poorly exposed on the ocean floor and as tectonically exhumed rocks, and sampled by sparsely distributed mantle-derived magmas carrying small fragments plucked from their wallrocks. Much of what we know relies on applying the petrologist’s ever-growing toolbox to these direct and indirect mantle samples. This is complemented by high-pressure experiments and computational models, which establish the phase relations and dynamic behaviour of mantle rocks, and the physical properties of its minerals.

Many mantle mysteries remain, reflecting the dearth of samples from deep Earth and deep time. Among these are the origin, size, locus and persistence of different mantle reservoirs recognised in mantle magmas of various ages, as reflections of mantle structure and convective vigour. Other key questions concern the mantle’s temperature and redox evolution, affecting its dynamic behaviour and melting relations through time, and the origin and cycling of its volatile element inventory, the partial degassing of which contributes to the air we breathe today.

description:
Calcium sulfates are the dominating salts in soils of the Atacama Desert (Chile) but respective sulfate sources are debated. Various sulfate sources comprise distinct isotopic compositions. To map the spatial distribution of sulfate sources and to identify biological sulfate recycling, we determined Δ17OSO4, δ18OSO4, δ34SSO4, and 87Sr/86Sr of surface samples from Atacama Desert soils taken along four W-E transects from the Pacific coast to the Pre-Andean Cordillera.

Distinct mass-independent 17O anomalies in sulfates originate from atmospheric oxidation of reduced sulfur species derived from volcanic emissions or dimethyl sulfide (DMS) a biogenic sulfur gas that emits from the ocean. Marine aerosols represent a mixture of marine sulfate and atmospherically oxidized DMS and thus comprise elevated Δ17OSO4. Biological sulfate recycling leads to oxygen isotope exchange with ambient water, resulting in Δ17OSO4 values that converge towards 0‰ and generally increasing δ18OSO4 values because water in the Atacama Desert is highly evaporated. Volcanic and marine sulfate aerosols are effectively distinguished by δ34SSO4. The combination of δ34SSO4 and 87Sr/86Sr allows to identify dissolution and re-precipitation of sulfate.

Our dataset reveals the distribution of sulfate sources for Atacama Desert soils. Post-depositional bio-alteration processes lead to changes in the isotopic composition allowing to draw conclusions on bio activity and water availability in such hyper-arid environments like the Atacama Desert.

description:
Lead isotopes are the most universally used method to reconstruct the raw material origin of archaeological objects made of lead, silver, copper, gold and their alloys, but also are routinely applied in e.g. ore deposit geology and environmental geochemistry. For all research utilising lead isotope signatures, a comprehensive compilation of existing reference data is essential. GlobaLID, a FAIR global ore lead isotope database coupled with an interactive web application, was set up as an open access repository and visualisation tool. The database was enriched by locally versed contributors with meta-information on geography, mineralogy, geology, metallogeny and analytical set-up of the original published data to allow their utilisation for a diverse range of research topics. The web application primarily serves the visualisation of the database. Different options for screening, filtering and plotting of the data are available, including the possibility to upload and plot user data and automatically match them to GlobaLID’s database.

A first version of the database and prototype of the web application were launched in late 2021. Feedback from the scientific community identified major issues to tackle in the on-going work on GlobaLID, e.g. the complete standardisation of revised datasets, the possible integration of further data and material types, and the additional implementation of statistical tools. The core team will create and implement a common standard for these tasks together with other researchers. Our presentation will first highlight GlobaLIDs most important features and subsequently present plans for its future development as a community-driven project.

description: We report the discovery of an extrasolar planet detected from the combined data of a microlensing event OGLE-2015-BLG-0051/KMT-2015-BLG-0048 acquired by two microlensing surveys. Despite that the short planetary signal occurred in the very early Bulge season during which the lensing event could be seen for just about an hour, the signal was continuously and densely covered. From the Bayesian analysis using models of the mass function, matter and velocity distributions combined with the information of the angular Einstein radius, it is found that the host of the planet is located in the Galactic bulge. The planet has a mass $0.72_{-0.07}^{+0.65}\ M_{\rm J}$ and it is orbiting a low-mass M-dwarf host with a projected separation $d_\perp=0.73 \pm 0.08$ AU. The discovery of the planet demonstrates the capability of the current high-cadence microlensing lensing surveys in detecting and characterizing planets.

description:
Using quadrupole ICP-MS, we determined the chemical composition of five basaltic Apollo 12 and six anorthositic Apollo 16 soil samples, the cataclastic lunar anorthosite 60015 and the reference samples BHVO-2 and AN-G.

The aim was to evaluate the processes affecting soil compositions and to provide data that allows for accurate spike additions for isotope dilution analyses of volatile elements and double-spike Cd isotope analyses, while consuming only a few mg of precious sample powder. Of the 56 elements analyzed, Ta, W and Bi for BHVO-2 and Be, P, As, Zr, Cd, Sn, Sb, W, Tl, Bi and U for AG-N deviate by more than 20% from reference values (mostly GeoReM). Deviations are not due to secondary fluorite precipitation, but may reflect residual memory and blank issues and incorrect reference data. The latter is evident for Cd in AN-G, as ICP-MS and double-spike data agree within 6%, while the compiled value is 170% higher.

Apollo 16 soils are dominated by feldspathic highland terrane compositions and Apollo 12 soils are dominantly mixtures between mare basalt and Procellarum KREEP terrane compositions. Higher incompatible element abundances in 12032 and 12033 reveal a larger KREEP component. Of the most volatile elements, Tl displays the least variation in soil samples, Cd and especially In scatter more. Their abundances do not correlate with soil maturity, suggesting that micrometeorite bombardment has no major effect on volatile element abundances. In Apollo 12 soils, the Cd and In abundances may be controlled by the basaltic microbreccia or the basalt component, respectively.

description:
Femtosecond laser ablation coupled to MC-ICP-MS has been proven to be a powerful means to analyze isotope ratios of “non-traditional” stable isotope systems with high spatial resolution, precision and accuracy. The technique has been successfully applied e.g. to investigate diffusion-generated Li- and Fe-Mg isotopic zoning in magmatic crystals. Here, we present a novel sampling technique employing a fs-LA system that is equipped with a CNC-controlled laser stage. This set up allows to perform depth profile analyses of major and trace elements as well as metal stable isotope variations (Li-Mg-Fe) and is particularly suitable for experimental samples with a well-defined crystal interface. Samples are ablated in circular patterns with diameters of 100-200 µm and the integrated signal of one layer represents one data point of the depth profile. Depth resolution is between 300 nm and 2.5 µm and depends on the scan speed and the repetition rate of the laser. We have tested this technique by analyzing chemical diffusion profiles in olivine crystal cubes which are compared to “horizontal” profile data acquired by electron microprobe analyses. Furthermore, Fe-Mg isotopic depth profiles were analyzed in a diffusion couple consisting of a 25Mg- and 57Fe-doped olivine thin film in contact with a natural olivine crystal cube. Our results indicate (i) that concentration data acquired by LA depth profiling match well with electron microprobe data, and (ii) that precise and accurate δ25Mg, δ26Mg, δ56Fe and δ57Fe data can be obtained.

description: Lattice kinetic Monte Carlo simulations have become a vital tool for predictive quality atomistic understanding of complex surface chemical reaction kinetics over a wide range of reaction conditions. In order to expand their practical value in terms of giving guidelines for atomic level design of catalytic systems, it is very desirable to readily evaluate a sensitivity analysis for a given model. The result of such a sensitivity analysis quantitatively expresses the dependency of the turnover frequency, being the main output variable, on the rate constants entering the model. In the past the application of sensitivity analysis, such as Degree of Rate Control, has been hampered by its exuberant computational effort required to accurately sample numerical derivatives of a property that is obtained from a stochastic simulation method. In this study we present an efficient and robust three stage approach that is capable of reliably evaluating the sensitivity measures for stiff microkinetic models as we demonstrate using CO oxidation on RuO2(110) as a prototypical reaction. In a first step, we utilize the Fisher Information Matrix for filtering out elementary processes which only yield negligible sensitivity. Then we employ an estimator based on linear response theory for calculating the sensitivity measure for non-critical conditions which covers the majority of cases. Finally we adopt a method for sampling coupled finite differences for evaluating the sensitivity measure of lattice based models. This allows efficient evaluation even in critical regions near a second order phase transition that are hitherto difficult to control. The combined approach leads to significant computational savings over straightforward numerical derivatives and should aid in accelerating the nano scale design of heterogeneous catalysts.

description: Presence of dyes in the aquatic systems has become a serious environmental problem. Concerning the environmental awareness and the economical point of view, the use of low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing textile dyes from wastewater. This study explores the feasibility of using orange peel, an agricultural waste, for removal of synthetic dye from aqueous solution. The adsorption characteristics of RR- DEXF dye onto powdered orange peel (POP) as a bio adsorbent that has been previously physically treated was investigated. Batch adsorption experiments were carried out for the adsorption of the dye molecule from aqueous solution onto the POPA at constant room temperature 27oC and agitation speed 200rpm. Variation effect of different parameters like solution pH, adsorbent dose, contact time and the initial concentration of the dye were studied. U V. spectrophotometer technique was used for the measurement of concentration of dye before and after adsorption. Experimental results revealed that optimal adsorption took place at an acidic solution pH. The effective solution pH, adsorbent dose and contact time on the dye removal efficiency of the adsorbent were found to be 3, 0.2g/100mL and 80min, respectively for the adsorption studies. At these experimental conditions the dye removal efficiency of 90% was achieved. The experimental results have been fitted well by the Langmuir isotherm model with the higher correlation coefficients of R2 Keywords: RR-DEXF dye; Powdered orange peel adsorbent (POPA); UV. Spectrophotometer; Adsorption isotherm; Kinetics models; effluents. = 0.995. Thus, indicating to the applicability of monolayer coverage of the dye on the surface of the adsorbent and it was found to be 3.03 mg/g. Adsorption kinetics was determined using pseudo first order and pseudo second order models and it was found that the adsorption process follows pseudo second order model. Generally the results indicate that POP may be used as a low cost adsorbent, alternative for treatment of effluents containing reactive red dye in water.

description: ABSTRACT
 End-Stage Renal Disease (ESRD) patients frequently experienced disturbed
 activities of daily living (ADL) and functional health pattern affecting their biophysical profile and state of mind. The study aimed to determine the effect of Virtual Reality Exposure (VRE) intervention to manage anxiety of End-stage renal disease patients in terms of improvement of Biophysical Profile and State of Mind undergoing hemodialysis as part of nursing intervention. The study was conducted in a dialysis center in Las Pinas City and in a tertiary hospital in Paranaque City. The research utilized Pre-post Experimental design. Assessment survey (biophysical profile and
 anxiety) were collected pre and post VRE during hemodialysis treatment and were observed all throughout three (3) sessions. From Purposive convenience sampling, thirty-three (33) were included. Throughout the (3) sessions, biophysical profile was observed to decrease every after VRE where Systolic BP (137 vs 130/bpm, p = < .00001), Diastolic BP (84 vs 81/bpm, p =.00174), Heart rate (79 vs 77/bpm, p = .00089) and Respiration (20 vs 19/cpm, p = .00048). Anxiety level of participants were also improved from 42 (high anxiety) vs 28 (low anxiety) where p value is <.00001. All throughout the visits, “state of mind’’ shows a significant reduction in scores for statements of ‘’not relax’’, ‘’contented’’, ‘’calm’’ and ‘’feeling worried.’’ Results also showed that there was a correlation between person’s state of mind and BP, also with HR. Respiration was very weakly correlated to state of mind (r=0.04) but insignificant (p=.825). This study revealed that integration of VRE was effective in reducing anxiety for pre-post VRE exposure. In conclusion, integrating VRE visualization helped ESRD patients changed their outlook by keeping a calm and relax state all throughout hemodialysis.

description:
Bivalves are important environmental archives that can provide past "climate snapshots" at high temporal resolution. The long-lived giant clam Tridacna builds large (< 1 m), dense aragonite shells in which seasonal to daily bands are recorded both structurally and chemically. Therefore, Tridacna have been key archives of seasonality and extreme weather events in (sub)tropical reefs since their appearance in the early Miocene. Detailed ontogenetic ages and growth rates can be assessed by counting the daily bands and measuring their intervals, which range from a few micrometres to tens of micrometres. However, in many areas of our late Miocene Tridacna shell, daily bands were not continuously countable. Continuous optical analyses of daily bands are also time-consuming in organisms that can live for up to a century. A more efficient approach is to utilize daily geochemical cycles, measured via ultrahigh-resolution Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS). First, daily geochemical cycles were recognizable even in areas where we failed to identify daily bands optically. Second, through computational evaluation of the daily cycles’ wavelengths (e.g., wavelet transform) we can develop daily growth rate models. Consequently, we can track the ontogenetic age and the growth-rate variability and compare it to the corresponding (sub)seasonal geochemical data (δ18O, El/Ca). This allows us to evaluate the relationships between geochemical signals, environmental parameters, and shell growth to tackle growth rate and ontogenetic effects as well as seasonal biases. Displaying geochemical data against time rather than shell distance further improves multi-annual and inter-organism comparisons of palaeoseasonality reconstructions.
Above-the-loop-top Oscillation and Quasi-periodic Coronal Wave Generation in Solar Flares

description: Observations revealed that various kinds of oscillations are excited in solar flare regions. Quasi-periodic pulsations (QPPs) in the flare emissions are commonly observed in a wide range of wavelengths. Recent observations have found that fast-mode magnetohydrodynamic (MHD) waves are quasi-periodically emitted from some flaring sites (quasi-periodic propagating fast-mode magnetoacoustic waves; QPFs). Both of QPPs and QPFs imply a cyclic disturbance originating from the flaring sites. However, the physical mechanisms remain puzzling. By performing a set of two-dimensional MHD simulations of a solar flare, we discovered the local oscillation above the loops filled with evaporated plasma (above-the-loop-top region) and the generation of QPFs from such oscillating regions. Unlike all previous models for QPFs, our model includes essential physics for solar flares, such as magnetic reconnection, heat conduction, and chromospheric evaporation. We revealed that QPFs can be spontaneously excited by the above-the-loop-top oscillation. It was found that this oscillation is controlled by the backflow of the reconnection outflow. The new model revealed that flare loops and the above-the-loop-top region are full of shocks and waves, which is different from the previous expectations based on a standard flare model and previous simulations. In this paper, we will show the QPF generation process based on our new picture of flare loops and will briefly discuss a possible relationship between QPFs and QPPs. Our findings will change the current view of solar flares to a new view in which they are a very dynamic phenomenon with full of shocks and waves.

Model masses and wavefunctions are used to predict radiative transition rates and the $^3P_0$ quark pair creation model is used to compute strong decay widths. A comparison to recently observed bottom and bottom-strange states is made. We find that there are numerous excited $B$ and $B_s$ mesons that have relatively narrow widths and significant branching ratios to simple final states such as $Bπ$, $B^*π$, $BK$, and $B^*K$ that could be observed in the near future.

Application of Dispersive Soils as a Sub Grade and Embankment Materials (Case Study on Adama – Awash Railway Section)
Creators: name: Yohannes, Woldechirkos
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Dispersive soils are prevalent in many areas of Ethiopia (especially in the rift valley). The use of dispersive soils in embankment structure can lead to serious engineering problems if the soil is not accurately identified before use and appropriate mitigation measures are not taken. The current tests used for identification include pinhole, double hydrometer, crumb and chemical tests. The main objective of this research is to use dispersive soil as an alternative embankment construction material. The light greyish sub grade soil of the pilot – study area (Adama – Welenchity section) have been tested with all identification tests of dispersive soil to check the extent of dispresivity of the soil. According to the result, the sub grade soil is dispersive with Pinhole test D2 (dispersive soil category 2), double hydrometer percent dispersion value TP1=87.17% and TP2=83.24%, crumb test result of grade 3 and Chemical analysis exchangeable sodium percentage of 31.93%. Treatments to dispersive clay using gypsum was carried out in this study. The optimum amount of gypsum required to treat a dispersive clay sample was 5%. The identification test results obtained by stabilizing with 5% recycled gypsum are: - double hydrometer percent dispersion value 24.72%, pinhole test ND1 (non-dispersive soil 1) and chemical analysis exchangeable sodium percentage of 6.54%. The engineering index tests of the dispersive soil have also been checked and found that the dispersive soil qualifies the specification requirement of embankment construction materials. After being treated with 5% recycled gypsum the dispersive soil can be used for embankment construction.

description: This research proposed coffee husk as a low-cost material for production of activated carbon and investigated its application for adsorption of Cr(VI) from aqueous solution. The initial work involved, the optimization of process parameters involved in preparation of activated carbon by chemical activation using H3PO4. Four parameters such as concentration of H3PO4, impregnation ratio, carbonization temperature and holding time were optimized by Response Surface Method (RSM) using Box-Behnken design technique and the produced activated carbon applied for Cr(VI) adsorption. RSM revealed that the effect of on operational parameters on Iodine number and yield of coffee husk activated carbon was best described by quadratic polynomial model. Analysis of variance (ANOVA) revealed a good agreement between experimental and predicted value. The characterization result showed that the coffee husk activated carbon has good properties and compared favourably with other reference activated carbons. FTIR test and point of zero charge pH, showed the presence of acidic functional groups on surface. Cr(VI) adsorption shows that the system was pH dependent. The linear regression analysis of kinetic data confirmed that pseudo-second order rate expression best fitted for all temperature. Langmuir equation was found to fit the equilibrium data for Cr(VI) adsorption with monolayer capacity of 78.74, 84.03 and 92.59 mg/g at 25, 35 and 45oC respectively. Thermodynamic analysis asserted endothermic and spontaneous nature of the system with involvement of chemical adsorption process.

Creation of data starts with sample collection in the field and the assigning of an unique global IGSN sample identifier to samples, these samples are stored along with any subsequent  analytical data in our fine-grained and detailed geochemical data models allowing visualising and publishing acquired datasets. This unique solution has been developed by Lithodat Pty Ltd in conjunction with the AuScope Geochemical Network (AGN) consisting of most Australian geochemical laboratories and can be accessed by the public on the AusGeochem web platform.

Using our field application users can enter and store all sample details on-the-fly during field collection, the data will be stored in the user's private data collection. After running subsequent geochemical analyses those results, including all metadata, can be stored in the relational database and be attached to the sample. Once uploaded, data can be visualised within AusGeochem, using data analytics via technique-specific dashboards and graphs. All data can be shared with collaborators, downloaded in multiple formats and made public enabling FAIR data for the research community.

Having all data stored in a clean and curated relational database with very detailed and fine-grained data models gives researchers free access to large amounts of structured and normalised data, helping them develop new technologies using machine learning and automated data integration in numerical models. Having all data in one place including all metadata such as ORCIDs from involved researchers, funding sources, grant numbers and laboratories enables the quantification and quality assessment of research projects over time.

description:
The Early Quaternary lacustrine deposits in the Niederschönhagen area (Detmold, NW Germany) represent an important archive for the paleoclimate record in continental northwestern Europe during the transition from the warm Pliocene to the cold Pleistocene. Niederschönhagen belongs to a subrosion series in the Weser Uplands in northwestern Germany. These subrosion structures were formed by the leaching of subsurface evaporitic rocks during the early Cenozoic. A large collapsed structure at Niederschönhagen resulted in the deposition of 170 m thick lacustrine deposits that span the latest Pliocene/earliest Pleistocene to present. Magnetostratigraphic analysis suggest a time span of ~2.7 – 1.9 Ma for the deposition of the lacustrine deposits at Niederschönhagen.

Our sedimentologic observation combined with X-ray diffraction (XRD) analyses indicate the presence of vivianite minerals in the context of greyish mudstone, which occurs between 140 m and 148 m. Vivianite is an authigenic ferrous iron phosphate mineral (Fe3(PO4)2·8H2O), associated with the development of redox conditions at the bottom of lakes. Dependence of magnetic susceptibility (MS) on the temperature of natural iron phosphate mineral are studied. The thermal MS curves for vivianite on heating curves shows an increase at 420 – 480 °C, and unstable magnetite (maghemite) is produced.

Our results suggest that northwestern Germany experienced a wet period during the latest Pliocene and earliest Pleistocene. This abstract is part of ongoing research, the main goal of which is to establish a rigid stratigraphic framework for the 170 m long lacustrine deposit of Niederschönhagen.

title: Denudation and weathering rates of carbonate lithologies from meteoric 10Be/9Be ratios

description:
During the past decades, cosmogenic nuclides, such as in-situ produced 10Be, evolved as state-of-the-art tool to quantify millennial-scale denudation in quartz-rich landscapes. However, applications of cosmogenic nuclides to carbonate-dominated lithologies are still rare, even though carbonate dissolution is a major weathering process that may compensate anthropogenically elevated CO2 levels over centennial-millennial timescales.

Recent advances in quantifying carbonate erosion have been made using cosmogenic 36Cl and of carbonate weathering using dissolved loads (e.g.[1],[2]). As these integrate over two distinct time-scales we developed a method that records such rates simultaneously: the cosmogenic meteoric 10Be over 9Be ratio (10Be/9Be). We adapted a framework[3] combining a known atmospheric flux tracer, meteoric 10Be (T1/2=1.4 My), with stable 9Be, a trace released from rocks by weathering, to the limestone-dominated French Jura Mountains. We analyzed water, soil, sediment, and bedrock for 10Be/9Be, major/trace elements, and Sr and C isotopes, to quantify i) Be contribution from carbonate vs. silicate minerals and ii) from primary vs. secondary carbonate phases, iii) solid-solute load partitioning, and iv) deep (sediment) vs. surficial (soils) weathering and erosion. Our results indicate average denudation rates of 300 t/km2/yr, denudation being dominated by weathering flux (W/D ratios of 0.7-0.97), and a consistently higher contribution from deep weathering. These rates agree to decadal-scale denudation rates from combined suspended and dissolved fluxes within < 2x which highlights the great potential of this method for future Earth’s surface studies.

description:
The Volyn biota, a distinct example of 3D-preservation of ~1.5 Ga old Precambrian fossils from huge cavities in granitic rocks as a habitat for microorganisms in the deep biosphere, consist of several different types of organisms. Most common are filaments of variable diameter (10 µm-range to 100 µm-range) and length up to cm. Branching, segmentation, outgrowths, and a central channel are typical. Ends can be simple rounded, thinning out, or with outgrowths. Filaments grew on mineral substrate (?sessile organisms); filaments with two ends indicate growth in soft clay media or floating in water. Spherical objects in the size of tens of µm could represent spores or other types of seeds. For larger objects, some with conical shape, in the 100 µm-range, no recent analogue is obvious. Bi(S,Te) nm-minerals in filaments, either irregularly distributed or in rod-like arrangement, have an analogue in recent fungi, but also in other microorganisms. Objects with flaky to irregular shape are reminiscent of a former biofilm. Filaments are also partly covered with a sheath, interpreted as extracellular protein substance. d 13C/12C-isotope values of approximately -40 ‰ to -50 ‰, typical for methanogenic bacteria, and a range of d 15N/14N-isotope values of +2‰ to +9 ‰ also indicate different organisms.

The crucial fact for the excellent 3D-preservation of the microfossils is their occurrence in cavities of igneous rocks, which preserved them from further diagenetic-metamorphic overprint as common in sediments. These microfossils give an impressive insight into Precambrian life in the deep biosphere.

description: In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both electron$-$proton ($e^{-}-p^{+}$) and electron$-$positron ($e^{\pm}$) relativistic jets containing helical magnetic fields, focusing on their interaction with an ambient plasma. We have performed simulations of "global" jets containing helical magnetic fields in order to examine how helical magnetic fields affect kinetic instabilities such as the Weibel instability, the kinetic Kelvin-Helmholtz instability (kKHI) and the Mushroom instability (MI). In our initial simulation study these kinetic instabilities are suppressed and new types of instabilities can grow. In the $e^{-}-p^{+}$ jet simulation a recollimation-like instability occurs and jet electrons are strongly perturbed. In the $e^{\pm}$ jet simulation a recollimation-like instability occurs at early times followed by a kinetic instability and the general structure is similar to a simulation without helical magnetic field. Simulations using much larger systems are required in order to thoroughly follow the evolution of global jets containing helical magnetic fields.

description:
Lead isotope data are an important tool for the reconstruction of raw material provenances of non-ferrous archaeological materials. The quality of the provenance reconstruction depends, among other factors, on the comprehensiveness of the reference data the archaeological samples can be compared to. When compiling such databases, three major challenges typically emerge: (a) Access to the respective publications, many of them scattered in conference proceedings and local journals; (b) a huge variety and often incompatibility and incompleteness of meta-information; and (c) language barriers. To overcome these obstacles, a group of colleagues started to tame this data monster in 2018 through the compilation of the global lead isotope database GlobaLID. Its aim is to create in a community-driven process a FAIR database and an associated web application which provides easy access to the database and visualisation tools for people with different backgrounds and knowledge levels. Prototypes were published in late 2021 and work is still ongoing.

Many obstacles had to be overcome; many more are already looming on the horizon. After a short summary of the project, some of them will be presented, which we perceive as general challenges in taming such data monsters, and the solutions we came up with. Subsequently we will discuss where we are in urgent need from the scientific communities and related research data infrastructures for tools that allow us to fully tame the data monster into a truly FAIR database.
