description:
Detection of small variations in triple oxygen isotope ratios (Δ’17O) of rocks, minerals, and water has opened new applications in the field of isotope geochemistry (1,2). A long-standing problem is extending the approach to CO2 and carbonates because of analytical difficulties getting precise Δ’17O of CO2. Direct measurement of Δ’17O of CO2 by means of high-resolution gas source mass spectrometry has been successfully demonstrated but requires measurement times of days for reaching a precision <10 ppm (3). Here, we present data of high-precision analyses of carbonate-derived CO2 and CO2 from the conversion of air O2 using a tunable infrared diode laser absorption spectroscopy (TILDAS) attached to a custom-built inlet system controlled by free software (PHP, Python, JavaScript, CSS, HTML) and low-cost electronic hardware, i.e., Raspberry Pi. With this device, we now achieve an external reproducibility as small as ±5 ppm. This opens new application fields, of which some will be presented.

description: Customs risk management plays an important role an achieving countrywide objective by enabling customs to allocate their scare resources efficiently, undertake balanced control and legitimate trade. Similarly to achieve its objectives; Ethiopian revenue and customs authority has built its capacity and made business process reengineering program so as to collect enough revenue, facilitate trade, contribute for promoting investment, regulate and control illegal trade by changing the customs clearance procedure from physical inspection toward risk management . Ethiopian revenue and customs authority has undertaken an initiative to restructure the way the risk management is managed and the way targeting services are delivered. The establishment of a functional risk management team to direct the targeting program will ensure that it receives the guidance and support to become more effective and efficient. Despite of this move to modernization, most goods are subjected to high customs intervention and international trade of the country that hurt facilitation of trade. This study is launched to assess the customs risk management system in Ethiopian revenue and customs authority Addis Ababa kality customs branch in relation to risk management process, the infrastructure in risk management, compliance measurement, and risk based compliance management, collection of data and information and facilitation and control of customs risk management. This objective has been supported by review of various literatures in area of customs risk management. The study used descriptive research methodology and both qualitative and quantitative research approaches. To conduct the study both primary and secondary data were gathered from 50 Employees of the customs, and 39 clearing agents of the branch based on probability and non-probability sampling techniques. Interviews were also conducted from central and branch risk management team leaders. Secondary data were collected from Automated System for Customs Data System, proclamation, and so on. The collected data were analyzed using descriptive statistics. According to the findings, it is difficult to say there is effective implementation of custom risk management process; there is also a gap on supporting infrastructure; the requirement for compliance measurement is implemented in a good condition; Finally the study recommends that the risk management at the branch as well as the authority should implement all the customs risk management processes effectively and efficiently the compliance measurement system should depend on harmonized data system, the intelligence team access information beyond domestic sources, fulfill IT infrastructure, and develop the capacity of risk management officers through training.

description: We report the serendipitous discovery of HSC J142449-005322, a double source plane lens system in the Hyper Suprime-Cam Subaru Strategic Program. We dub the system Eye of Horus. The lens galaxy is a very massive early-type galaxy with stellar mass of ~7x10^11 Msun located at z_L=0.795. The system exhibits two arcs/rings with clearly different colors, including several knots. We have performed spectroscopic follow-up observations of the system with FIRE on Magellan. The outer ring is confirmed at z_S2=1.988 with multiple emission lines, while the inner arc and counterimage is confirmed at z_S1=1.302. This makes it the first double source plane system with spectroscopic redshifts of both sources. Interestingly, redshifts of two of the knots embedded in the outer ring are found to be offset by delta_z=0.002 from the other knots, suggesting that the outer ring consists of at least two distinct components in the source plane. We perform lens modeling with two independent codes and successfully reproduce the main features of the system. However, two of the lensed sources separated by ~0.7 arcsec cannot be reproduced by a smooth potential, and the addition of substructure to the lens potential is required to reproduce them. Higher-resolution imaging of the system will help decipher the origin of this lensing feature and potentially detect the substructure.

description: We develope a computationally efficient extension of the Dyson Brownian Motion (DBM) algorithm to generate random function in C2 locally. We further explain that random functions generated via DBM show an unstable growth as the traversed distance increases. This feature restricts the use of such functions considerably if they are to be used to model globally defined ones. The latter is the case if one uses random functions to model landscapes in string theory. We provide a concrete example, based on a simple axionic potential often used in cosmology, to highlight this problem and also offer an ad hoc modification of DBM that suppresses this growth to some degree.

description:
The characteristics of half-precession (HP) cycles (~9,000 - 12,000 years) are still poorly understood, despite their appearance in numerous records. Previous studies on European terrestrial and marine records indicate a connection of the HP-signal to low latitudes. Consequently, we investigate HP-cycles in equatorial regions, which is the assumed origin of this signal.

Spectral analysis, evolutive approaches and correlation techniques are used on records from ODP Site 663 to identify the HP-signal in elemental ratios reflecting e.g. terrigenuous input and/or bioproductivity. Filters that remove the classical orbital cycles (eccentricity, obliquity, precession) allow to isolate the HP-signal and to determine its temporal evolution.

We present first results of a larger project which has the overall objective to characterize the HP-signal during and  beyond the Mid-Pleistocene Transition (MPT) at Site 663. The connection of (half-)precession to eccentricty implies a weaker influence of HP during the MPT, as the major driver of climate forcing during this period is the 41-kyr obliquity cycle. Further objectives of the investigations will be to link the orbital patterns of Site 663 to terrestrial records, e.g. from the ICDP project on Lake Bosumtwi (Ghana). This will contribute to a better understanding of paleoenvironmental processes in Equatorial Africa.

description:
In this study, we present B isotopic data for cold-water corals at high spatial resolution determined by UV femtosecond laser ablation system coupled to a Nu Plasma II MC-ICP-MS. Boron isotope records in biogenic carbonates provide constraints on the evolution of seawater pH and insights into biomineralization processes. We investigated B isotopic ratios in recent cold-water corals (Desmophyllum dianthus) from a field experiment in the Comau Fjord (Chile) to resolve seasonal variations. Corals from the head and the mouth of the fjord and from different water depths were stained with calcein, replaced at the same location or cross-transplanted and observed for a whole year to investigate time-resolved environmental signatures and potential adaptation effects under new environmental conditions. B isotopic ratios were measured at the upper part of the calyx in transverse sections between septa at the skeletal increment. δ11B values range between 23.5 and 27.0‰ and varies with seasonality and location in the fjord. Isotope signature of cross-transplanted corals do not differ significantly from those of local corals showing that the recorded signature is directly influenced by environmental conditions. B isotopic signatures correspond to an internal pH up-regulation for calcification of 0.78 to 1.14 pH units, which is likely controlled by ambient seawater pH and nutrient availability. These results show the potential of in situ techniques to decipher marine archive to reconstruct environmental conditions.
Comparison of Floating Ladder Track and RHEDA2000Ballast-less Track for Dynamic Responses
Creators: name: Aklilu, Bekele
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The purpose of this thesis is concerned with the comparison of FLT and RHEDA2000 ballast-less Track-form with respect to their dynamic performances. The comparison is done based on the analysis of the simulation results and it would be achieved via FEM software (ABAQUS). The analysis have been done in time domain at various Speed of the moving Load and the mode of vibration as well as natural frequencies of both track-forms were extracted from frequency domain analysis. The analysis is done by varying the speed of the rotating wheel from 120 to 420 Km/hr and keeping track stiffness"s constant. As the speed of the moving load increases from 120 to 420 Km/hr, the vertical displacement of the rail in FLT is increasing to nearly 8mm, in contrast the vertical displacement of Rheda2000 is slightly increasing to 3mm throughout their time domain. With similar manner, the comparisons of these Tracks" with respect to peak value of stresses variation on the Rail have been done and in FLT this value vary from 130Mpa to 250Mpa in its time domain. Then again, the maximum stresses on Rheda2000 ballast-less Track varies from 136Mpa to 160Mpa in its" time domain. Besides, it is possible to understand that the vertical acceleration level of Rail in FLT is comparatively less than the vertical acceleration of Rail in Rheda2000 ballast-less Track. The maximum acceleration level of Rail in FLT is 70m/s2 and maximum acceleration level of Rail in Rheda2000 is about 200m/s2. Moreover, from the analysis, it was found that FLT has better capacity of vibration reduction than Rheda2000 ballast-less Track at higher frequency but at frequency lower than 400Hz, there is no much difference in both track forms. The other dynamic responses of both track-forms are nearly comparable and in both tracks form as the speed of the moving load increases the dynamic response increases. However, at similar speed of moving load, the dynamic performance of Rheda2000 ballast-less track is better than the dynamic performance of FLT. From the discussion, it could be deduce that FLT is good for vibration reduction and Rheda2000 have better dynamic performances.

description: We use deep optical photometry from the Next Generation Virgo Cluster Survey [NGVS] to investigate the color-magnitude diagram for the galaxies inhabiting the core of this cluster. The sensitivity of the NGVS imaging allows us to continuously probe galaxy colors over a factor of $\sim 2 \times 10^5$ in luminosity, from brightest cluster galaxies to scales overlapping classical satellites of the Milky Way [$M_{g^{\prime}}$ $\sim$ $-$9; $M_{*}$ $\sim 10^6$ M$_{\odot}$], within a single environment. Remarkably, we find the first evidence that the RS flattens in all colors at the faint-magnitude end [starting between $-$14 $\le$ $M_{g^{\prime}}$ $\le$ $-$13, around $M_{*}$ $\sim 4 \times 10^7$ M$_{\odot}$], with the slope decreasing to $\sim$60% or less of its value at brighter magnitudes. This could indicate that the stellar populations of faint dwarfs in Virgo's core share similar characteristics [e.g. constant mean age] over $\sim$3 mags in luminosity, suggesting that these galaxies were quenched coevally, likely via pre-processing in smaller hosts. We also compare our results to galaxy formation models, finding that the RS in model clusters have slopes at intermediate magnitudes that are too shallow, and in the case of semi-analytic models, do not reproduce the flattening seen at both extremes [bright/faint] of the Virgo RS. Deficiencies in the chemical evolution of model galaxies likely contribute to the model-data discrepancies at all masses, while overly efficient quenching may also be a factor at dwarf scales. Deep UV and near-IR photometry are required to unambiguously diagnose the cause of the faint-end flattening.

description:
Dissolution and precipitation of minerals in the presence of a hydrous fluid is commonly assumed to occur predominantly by hydrolysis of the outermost monolayers of the reacting crystal and subsequent incorporation of atoms from aqueous solutions into favorable sites at the product surface. However, experiments have shown that different parts of this classical reaction pathway are facilitated and enhanced by the presence of nanoparticles and/or amorphous phases.   

We show in natural high-pressure/low temperature rocks, which experienced metamorphic conditions in the order of 500°C at 1 GPa, that an alkali-Al-Si-rich amorphous material can be found in nm-sized metamorphic porosity [1]. The gel-like water-rich material contains about 15wt% total dissolved solids (TDS), which is more than ten times higher than expected for aqueous solutions at these metamorphic conditions. High-resolution TEM observations show that the amorphous material forms directly by depolymerization of the crystal lattice of amphiboles and clinopyroxenes. Depolymerization of the minerals starts along grain or phase boundaries, dislocation cores within the crystal lattice or lattice defects in general that serve as effective element exchange pathways and are sites of porosity formation. High hydrogen concentrations in such dislocation cores within nominally anhydrous clinopyroxene has been confirmed by Nano-SIMS measurements and indicates hydrolysis and recrystallization within mineral grains.

The resulting amorphous material occupies large volumes in an interconnected porosity network which has been documented in 3D imaging. Precipitation of product minerals occurs directly by repolymerization of the amorphous material at the product surface.

Year: 2014

description: Global climate change has increasingly gained worldwide attention. The concentration of greenhouse gases in our atmosphere is becoming an issue of increasing concern. To address this problem, it is believed that examining greenhouse gas emissions from different sources is important .Quantification of greenhouse gas emissions from composting facilities is necessary to quantify actual emissions from these systems and which requires a life cycle (cradle to grave) approach. This thesis identifies, quantifies, evaluates and recommends the environmental impact (global warming potential) associated with the flower farm waste composting process using life cycle analysis (LCA) according to ISO14000(2004). The system considered in this study include receipt of source from the farm , transport to the compost production area , production of mature compost and application of compost to a soil for subsequent agricultural application by planting a plant .Under composting emission (Etotal);Transport emission (Te), Process emission (Pe) and Fugitive emission (Fe) were the three Composting system emissions. The result demonstrates that from the three emission categories, transportation is the highest emitter with 59% CO2 eq than fugitive and process emissions. The results for CO2, CH4, and N2O indicate that CO2 is the most significant contributor in all three emission categories with values of 145.26 kg/ton for transport emissions, 90.75 kg/ton for fugitive emissions, and 11.18 kg/ton for process emissions. Compared to CO2 the contributions of CH4 and N2O are insignificant with values running from 0 to 8.09E-03 for CH4 and 0 to 3.66E-03 for N2O. In general composting emission (Etotal) the benefit of post application impact (Btotal) and the Compost Emission Reduction Factor (CERF) became 249.403 kg CO2 eq, 653.44 kgCO2eq and 404.037 CO2eq per ton of feedstock respectively. The results of this study indicates significant environmental benefits arise from the commercial composting system, including net greenhouse benefits, even where the compost is transported significant distances (200kms radius) for agricultural application. Key words: greenhouse gas emissions, global warming potential, cradle to grave, fugitive emission, Transport emission, Process emission, Composting emission, Emission Reduction Factor

description:
High Field Strength Elements (HFSE) are a powerful proxy to investigate specific processes occurring in complex magmatic settings. Being only little released by slab derived fluids/melts, HFSE are not easily overprinted by subduction processes and are also sensitive to peculiar metasomatic processes such as carbonatite infiltrations. We report high-precision HFSE isotope dilution concentration and 176Hf/177Hf data from representative magmas of the Neogene to Quaternary Italian volcanism (i.e., Vesuvius and other Central Italy volcanoes, Tyrrhenian seafloor, Etna, and Pantelleria).

Etna and Vulture volcanic rocks show Nb/Ta ratios much higher than OIB and MORB. The high Nb/Ta cannot be explained by an influence of the Ionian subduction and may reflect carbonatite metasomatism in the mantle. A C-rich metasomatic event explains the large CO2 degassing of Etna and it is consistent with a mantle flow that erodes the bottom portions of the SCLM.

Other Italian volcanoes do not show an anomalously high Nb/Ta with the exception of leucite-bearing rocks from Mid Latin Valley (Central Italy). Hafnium isotopes are partially decoupled from Nd isotopes. Vulture, Vesuvius, and leucite-free magmas from Mid Latin Valley show variations in 143Nd/144Nd, but rather constant 176Hf/177Hf. Given the lower mobility of Hf (with respect to Nd) during subduction processes, the constant 176Hf/177Hf could reflect a common asthenospheric component. Since the Tyrrhenian seafloor and intraplate volcanoes of the region (e.g., Pantelleria and Etna) show more radiogenic Hf, the signature of Vesuvius, Vulture, and leucite-free rocks of the Mid Latin Valley could reflect a less depleted asthenospheric mantle source.

description: Today, small and medium-sized enterprises (SMEs) in the software industry face major challenges. Their resource constraints require high efficiency in development. Furthermore, quality assurance (QA) measures need to be taken to mitigate the risk of additional, expensive effort for bug fixes or compensations. Automated static analysis (ASA) can reduce this risk because it promises low application effort. SMEs seem to take little advantage of this opportunity. Instead, they still mainly rely on the dynamic analysis approach of software testing. In this article, we report on our experiences from a technology transfer project. Our aim was to evaluate the results static analysis can provide for SMEs as well as the problems that occur when introducing and using static analysis in SMEs. We analysed five software projects from five collaborating SMEs using three different ASA techniques: code clone detection, bug pattern detection and architecture conformance analysis. Following the analysis, we applied a quality model to aggregate and evaluate the results. Our study shows that the effort required to introduce ASA techniques in SMEs is small (mostly below one person-hour each). Furthermore, we encountered only few technical problems. By means of the analyses, we could detect multiple defects in production code. The participating companies perceived the analysis results to be a helpful addition to their current QA and will include the analyses in their QA process. With the help of the Quamoco quality model, we could efficiently aggregate and rate static analysis results. However, we also encountered a partial mismatch with the opinions of the SMEs. We conclude, that ASA and quality models can be a valuable and affordable addition to the QA process of SMEs.

title: Making flour the German way: imported lava querns and millstones in Roman Britain
Creators: name: Banfield, Lindsay
Publisher: name: University of Reading
Year: 2022

description: The importance of food processing in the past is evident from the frequent occurrence of milling tools on archaeological sites. During the Roman period in Britain, imported lava milling tools complement those of indigenous stone types, but distribution and use of lava in the province has never been systematically examined. This research presents the first study of this material in Roman Britain, cataloguing and analysing 2,707 lava milling tools from 564 sites. A further 601 sites where lava was absent but other lithologies occurred have also been recorded. Analysis was completed using an object biography approach to investigate the key stages of manufacture, distribution, primary use, reuse/modification, and deposition at various case study sites to reflect lava milling tool use in rural, urban, and military contexts. Quarrying and manufacture of lava milling tools at Mayen, Germany, was examined in detail, and distribution analysis was undertaken to explore spatial, chronological, and social distribution. This has demonstrated that lava consumption was limited geographically and socially, with regions in the south-east and east of England, alongside military and urban sites being most likely to use lava milling tools. Lava millstones were most common in southern urban and northern military contexts, showing that access and use of centralised food processing technology was unequal. Chronological analysis of lava distribution has shown that the earliest lava imports occurred in the first century, with a peak in deposition during the second to third centuries. Evidence for the modification of lava querns has provided insight into innovation and specific modes of lava quern use, while varying use wear prior to deposition points to privileged access to imported lava at urban and military sites compared to rural ones. Analysis of deposition suggests that lava querns were ritually deposited in pits in urban contexts, and that reuse in construction and road surfaces was common at military sites. Overall, this study has generated a large corpus of new data, the analysis of which has delivered previously unknown detail of the role of lava milling tools in Roman Britain. The dataset also creates the potential for future analysis to help build a more complete view the complex biographies of these significant objects and their relationship with past peoples.

description:
Traditionally, “laser-ablation-geochronologist” have taken advantage of the developments in analytical techniques; trying to improve the spatial resolution in their analysis; i.e. reducing the spot size as much as possible. On the other hand, those advances in instrumentation have opened not only the possibility of analysing smaller sample volumes but also lower concentrations. Minerals with low U (and Pb) contents (< 1 µg/g) like garnet have become the target of in-situ U-Pb geochronology since it has been demonstrated that isochrons can be potentially obtained. In this contribution, we explored the current limits of in-situ U-Pb geochronology: what are the minimum Uranium concentrations from which an accurate and precise U-Pb age can be obtained?

For that purpose, we have analysed garnets from different localities that were unsuccessfully analysed in the past using single-collector instruments. These garnets have been re-measured using a Neptune Plus MC-ICP-MS coupled to a RESOLution-LR ArF Excimer laser. The analyses were performed in static mode measuring the masses 206Pb and 207Pb with Secondary Electron Multiplier (SEM) and 202Hg, 204Pb and 238U with the Multiple Ion Counters (MIC). The analysed garnets have typically U contents below 10 ng/g, which taking into account the spots sizes used, results in a Uranium amount ca. 3,000 times less than compared to conventional LA-ICPMS zircon analysis. About 15–30 spots are sufficient for a regression line in the Tera-Wasserburg diagram, yielding a precision of typically <3 % for the lower intercept age. The analysed. Challenges and details of the method will be discussed.

We consider the problem of learning, from indirect observations, two families of time-dependent processes of interest in Bayesian nonparametrics: the first is a dependent Dirichlet process driven by a Fleming-Viot model, and the data are random samples from the process state at discrete times; the second is a collection of dependent gamma random measures driven by a Dawson-Watanabe model, and the data are collected according to a Poisson point process with intensity given by the process state at discrete times. Both driving processes are diffusions taking values in the space of discrete measures whose support varies with time, and are stationary and reversible with respect to Dirichlet and gamma priors respectively. A common methodology is developed to obtain in closed form the time-marginal posteriors given past and present data. These are shown to belong to classes of finite mixtures of Dirichlet processes and gamma random measures for the two models respectively, yielding conjugacy of these classes to the type of data we consider. We provide explicit results on the parameters of the mixture components and on the mixing weights, which are time-varying and drive the mixtures towards the respective priors in absence of further data. Explicit algorithms are provided to recursively compute the parameters of the mixtures. Our results are based on the projective properties of the signals and on certain duality properties of their projections.

description: Prestressed concrete sleepers are the most widely used sleeper type in various countries for railway track system. This thesis evaluates the flexural performance of Australian German, British and Chinese prestressed concrete sleepers in comparison with the currently used sleeper in Ethiopia. The state of art of literature review has been discussed in order to assess the experiences of these countries in railway prestressed concrete sleeper. Codes of standards for prestressed sleeper recommended different types of concrete sleepers according to track gauge and axle load capacity. Sleepers are subjected to different types of load such as quasistatic, dynamic load and combined quasistatic and dynamic loading. In some codes like British and German accidental, exceptional and services load are included in the design. Finite element (FE) modeling and analysis is performed using FE software packages ANSYS. The design rail seat load is calculated according to the code provisions of respective countries code of standard. For comparison of the results of rail seat and sleepers center positive and negative loadings, AREMA standard is used as a reference. The result obtained from both rail seat positive and negative loads shows a good result which is below AREMA recommendations. For results obtained from sleeper center loading there was a variation of about average of 20%. The second FE analysis has been conducted according to actual ballast pressure distribution under sleepers provided by each country code and Chinese code. From the analysis result it has been observed that, the Australian and German concrete sleeper shows a good response at rail seat and sleeper center respectively. The German concrete sleeper relatively shows a better result when compared to British concrete sleeper under both rail seat and sleeper center. Finally, dynamic analysis has been made to see how these loads affect the flexural performance of concrete sleepers. The result showed that the Australian and china concrete sleepers observed a large amount of deflection when compared to other. In contrast the German concrete sleeper showed a small deflection. Based on the analysis result the German concrete sleeper was selected in terms of its general flexural performance. Lastly, the recommended sleeper cross-section shows a reduced stress when compared with others concrete sleepers.

title: Timing and metamorphism of the root of a magmatic arc on the West Gondwana margin: a case study of the Socorro Nappe and São Roque Domain in south-eastern Brazil

description:
The assembly of West Gondwana resulted in a high-grade nappe system of south-eastern Brazil that comprises a magmatic arc remnant (Socorro-Guaxupé Nappe). The UHT metamorphism is product of the collision between the Paranapanema block (active margin) and the São Francisco craton (passive margin) and decompression, but also related to a pre-collisional stage (Rocha et al., 2017; Tedeschi et al., 2018). The U-Pb ID-TIMS and U-Th-PbT EPMA monazite peak metamorphic ages systematically decrease towards the lower nappes describing an orogenic front migration from ca. 630-570 Ma (Campos Neto et al., 2011; Westin et al., 2021). The southernmost segment (Socorro Nappe) comprises gneisses with varied degrees of migmatization that unveil UHT-HT conditions, e.g., spinel + quartz and melt (quartz + K-feldspar) inclusions in garnet, neosomes with garnet + orthopyroxene and garnet + cordierite that are associated with amphibole ± pyroxene-bearing mesocratic gneisses. The paragneisses host a peak assemblage of garnet + sillimanite (needle trail inclusions) whereas biotite + sillimanite in the foliation are potentially retrograde. SEM-MLA and BSE imaging of monazite reveal complex microstructures. Monazite from the paragneisses displays homogeneous, moderate zonation and/or cloudy internal structures. A spinel-cordierite-garnet leucosome hosts peritectic garnet in which monazite inclusions are cloudy and weakly zoned. EPMA core-to-rim profiles of garnet show Fe-Mg zonation in a paragneiss whereas none in the neosomes. The overall composition is almandine and pyrope (XAlm 55-70%; XPrp 25-37%) and low Ca. We combine geothermobarometry and petrochronology of monazite to understand the metamorphic transition from lower to upper crustal rocks in the Neoproterozoic orogen.
Defunding the Police as Environmental Justice
Creators: name: Wilson, Alexandrea
Publisher: name: Unknown

description: Policing, rooted in the surveillance of Black folks and used to subordinate minority communities, is often understood as an icon of institutional racism. Environmental racism refers to the policies that create and build on racial disparities, again in terms of the space in which people live. Food insecurity, climate change, and air pollution are the symptoms of environmental racism because they disproportionately impact low-income communities of color. This paper explores the connection between two responses to these forms of anti-Black violence embedded in space: the environmental justice movement and the defund the police movement. It argues that anti-Black violence, through policing, contributes to the normalization of environmental racism that primarily burdens Black and Brown communities. It closes with discussing the contribution that social workers could potentially provide to the environmental field and what a focus on the environment in which people live could mean for social work more broadly.

description: In the next decade, new astrophysical instruments will deliver the first large-scale maps of gravitational waves and radio sources. Therefore, it is timely to investigate the possibility to combine them to provide new and complementary ways to study the Universe. Using simulated catalogues appropriate to the planned surveys, it is possible to predict measurements of the cross-correlation between radio sources and GW maps and the effects of a stochastic gravitational wave background on galaxy maps. Effects of GWs on the large scale structure of the Universe can be used to investigate the nature of the progenitors of merging BHs, the validity of Einstein's General Relativity, models for dark energy, and detect a stochastic background of GW. The results obtained show that the galaxy-GW cross-correlation can provide useful information in the near future, while the detection of tensor perturbation effects on the LSS will require instruments with capabilities beyond the currently planned next generation of radio arrays. Nevertheless, any information from the combination of galaxy surveys with GW maps will help provide additional information for the newly born gravitational wave astronomy.

description: Abstract Warm and saline water of Atlantic origin is transported across the Greenland Scotland Ridge into the Arctic Mediterranean. This inflow has a large impact on e.g. the climate and sea-ice in the Arctic and the knowledge of its variability and possible trend is therefore of huge importance in predicting Arctic climate change. The inflow has been monitored since the late 1990s with moored instrumentation combined with regular hydrographic cruises and data from satellite altimetry, but deploying moorings in the heavily fished region close to the Greenland Scotland Ridge is highly demanding in terms of manpower and funding. Efforts have therefore been made to optimize the monitoring systems, lately within the H2020 Blue-Action project. This has led to systems, which rely heavily on satellite altimetry. More recently moored PIES (Pressure Inverted Echo Sounders) have been used in a pilot project to monitor short-term variations of the temperature and salinity fields and these results look promising.

description: An important constraint for galaxy evolution models is how much gas resides in galaxies, in particular at the peak of star formation z=1-3. We attempt a novel approach by letting long-duration Gamma Ray Bursts (LGRBs) x-ray their host galaxies and deliver column densities to us. This requires a good understanding of the obscurer and biases introduced by incomplete follow-up observations. We analyse the X-ray afterglow of all 844 Swift LGRBs to date for their column density $N_H$. To derive the population properties we propagate all uncertainties in a consistent Bayesian methodology. The $N_H$ distribution covers the $10^{20-23}\mathrm{cm}^{-2}$ range and shows no evolutionary effect. Higher obscurations, e.g. Compton-thick columns, could have been detected but are not observed. The $N_H$ distribution is consistent with sources randomly populating a ellipsoidal gas cloud of major axis $N_H^\text{major}=10^{23}\mathrm{cm}^{-2}$ with 0.22 dex intrinsic scatter between objects. The unbiased SHOALS survey of afterglows and hosts allows us to constrain the relation between Spitzer-derived stellar masses and X-ray derived column densities $N_H$. We find a well-constrained powerlaw relation of $N_H=10^{21.7}\mathrm{cm}^{-2}\times\left(M_{\star}/10^{9.5}M_{\odot}\right)^{1/3}$, with 0.5 dex intrinsic scatter between objects. The Milky Way and the Magellanic clouds also follow this relation. From the geometry of the obscurer, its stellar mass dependence and comparison with local galaxies we conclude that LGRBs are primarily obscured by galaxy-scale gas. Ray tracing of simulated Illustris galaxies reveals a relation of the same normalisation, but a steeper stellar-mass dependence and mild redshift evolution. Our new approach provides valuable insight into the gas residing in high-redshift galaxies.
