description:
The Asse salt structure is a salt-cored anticline with steep, locally overthrusted flanks located in the Subhercynian Basin. It is an excellent example of salt structures in the North German Basin containing a wedge-shaped intrusion of Upper Permian into Upper Triassic salt (‘salt wedge’). The Asse is also known as a location for the disposal of low- and intermediate-level radioactive waste emplaced in the former salt mine Asse II during the 1970s. Detailed knowledge of the tectonic structures is indispensable for planning new retrieval infrastructure and for long-term safety analysis. The Asse salt structure has been thoroughly explored for over 100 years by surface geological mapping, 2D seismic and drilling. Ongoing exploration provides further insights into the salt structures and strengthens our understanding of its evolution.

A new 3D seismic data set (2019-2020) provides new insights into the details of this salt structure. Here we present first results of the seismic interpretation revealing substantial changes in the structural style opposing previous geological models. It can be shown that the sub-horizontal northern flank terminates at the base of the southern flank implying a north-ward instead of a south-ward directed overthrusting. Small-scale faults crossing the crest were previously interpreted as transpressional faults developed during the Late Cretaceous inversion. Ongoing kinematic modeling suggests that these faults originated as steeply dipping pre-Cretaceous normal faults that were overprinted during flank-rotation. These implications as well as observations of thickness variations and unconformities in Mesozoic layers will help to reconstruct the evolution of the Asse salt structure.

description: We investigate the nature and the physical properties of z, Y and J-dropout galaxies selected behind the lensing cluster A2667. This field is part of our project aimed at identifying z~7-10 candidates accessible to spectroscopic studies, based on deep photometry with ESO/VLT HAWK-I and FORS2 (zYJH and Ks-band images, AB(3 sigma)~26-27) on a sample of lensing clusters extracted from our multi-wavelength combined surveys with SPITZER, HST, and Herschel. In this paper we focus on the complete Y and J-dropout sample, as well as the bright z-dropouts fulfilling the selection criteria by Capak et al. (2011). 10 candidates are selected within the common field of ~33 arcmin2 (effective area once corrected for contamination and lensing dilution). All of them are detected in H and Ks bands in addition to J and/or IRAC 3.6/4.5, with H(AB)~23.4 to 25.2, and have modest magnification factors. Although best-fit photometric redshifts place all these candidates at high-z, the contamination by low-z interlopers is estimated at 50-75% level based on previous studies, and the comparison with the blank-field WIRCAM Ultra-Deep Survey (WUDS). The same result is obtained when photometric redshifts include a luminosity prior, allowing us to remove half of the original sample as likely z~1.7-3 interlopers with young stellar pulations and strong extinction. Two additional sources among the remaining sample could be identified at low-z based on a detection at 24 microns and on the HST z_850 band. These low-z interlopers are not well described by current templates given the large break, and cannot be easily identified based solely on optical and near-IR photometry. Given the estimated dust extinction and high SFRs, some of them could be also detected in the IR or sub-mm bands. After correction for likely contaminants, the observed counts at z>7.5 seem to be in agreement with an evolving LF. (abridged)

Pestilential policy and migratory maladies : the American state, epidemic disease policy, and migration, 1890–1915
Creators: name: Louie, Naomi Jane Linthwaite
Publisher: name: University of British Columbia
Year: 2023

description: This thesis examines the development of American public health institutions and public health policy during the Progressive Era through the interplay of the twin issues of anti-epidemic disease policy and immigration and rethinks the relationship between race, migration, policy, and public health. It investigates three disease epidemics that occurred during the late nineteenth and early twentieth centuries, in which migrants figured prominently: the 1892 cholera outbreak in New York City, the 1900 plague epidemic in San Francisco, and the typhoid fever outbreaks started by the woman who came to be known as Typhoid Mary. Through these three case studies, this thesis argues that though American public health institutions greatly expanded their reach in this period as the central state took on the primary responsibility for protecting the nation’s health, these institutions remained shakier and more vulnerable to challenges than the secondary literature has appreciated. I demonstrate this trend by studying the perspectives of both the pub-lic health officials implementing anti-epidemic policies and the migrants caught up in these poli-cies, highlighting the roles played by challengers to public health policy. These “resisters,” as I term them, were a broad group of disparate individuals ranging from the political and racial elite, to racially and politically marginalized migrants; their resistance constrained public health offi-cials’ actions and the range of policy tools wielded by public health agencies. Finally, in light of this pattern, this thesis draws a comparison between public health in the Progressive era and the Covid-19 pandemic in twenty-first century America. I suggest that the vulnerabilities in the pub-lic health system exposed by the Covid-19 pandemic are part of a much longer history, and arose in part because America’s system of public health sits atop institutional foundations that were never particularly sturdy even at the time they were built.

description: We consider semiclassically scaled Schrodinger equations with an external potential and a highly oscillatory periodic potential. We construct asymptotic solutions in the form of semiclassical wave packets. These solutions are concentrated (both, in space and in frequency) around the effective semiclassical phase-space flow obtained by Peierl's substitution, and involve a slowly varying envelope whose dynamics is governed by a homogenized Schrodinger equation with time-dependent effective mass. The corresponding adiabatic decoupling of the slow and fast degrees of freedom is shown to be valid up to Ehrenfest time scales.

Consequently, positronium is an attractive system for the investigation of possible violations of the discrete symmetries in the leptonic sector. We discuss signals for CP and CPT violation in the decay of spin-polarized orthopositronium and show where such correlations might arise in the context of the Standard-Model Extension.

description:
A pilot plant for an aquifer thermal energy storage (ATES) system in a contaminated aquifer is under construction at the scientific park of Leipzig. The research at this pilot plant is focused on developing and testing technologies to simultaneously store energy from shallow aquifers through an ATES system and remediate the contaminated aquifer.

For this purpose, investigations will be conducted in an approximately 10-meter-deep sandy/gravelly aquifer which is contaminated with chlorinated volatile organic compounds (Cl-VOCs). The main contaminants are trichloroethene (TCE, up to 6.0 mg/l) and cis-dichloroethene (cis-DCE, up to 0.4 mg/l).

With a two-well system that runs cyclically, the proposed ATES system will inject up to 80 °C heated water. This has a greater impact on the chemical composition of the groundwater than ATES systems that operate at lower temperatures. A previous field project revealed a considerable change in hydrogeochemistry and the microbiological community at temperatures of 45 °C and 60 °C.

As a result, this study investigates the hydrochemical and biological interactions that occur in the extraction and injection wells, the thermally affected aquifer as well as in the aboveground system. Cl-VOCs will be removed from groundwater using an on-site regenerable zeolite absorber (Fe-zeolite) and in situ degradation with persulphate.

Furthermore, these investigations will be supported by stable isotope biochemical and abiotic migration investigations of Cl-VOCs as well as microbiological and geochemical analyses including trace elements. It is anticipated to enhance the carbon footprint of urban energy management by the ATES operation, including groundwater remediation.

description: The periodic Anderson lattice model for the crystalline electric field (CEF)split 4f quartet states is used to describe the Yb-based Kondo insulators/semiconductors. In the slave-boson mean-field approximation, we derive the hybridized quasiparticle bands, and find that decreasing the hybridization difference of the two CEF quartets may induce an insulator-to-metal phase transition. The resulting metallic phase has a hole and an electron Fermi pockets. Such a phase transition may be realized experimentally by applying pressure, reducing the difference in hybridization of the two CEF quartets.

More evidence for extinction of activity in galaxies

description: This Research Note amends an article in which we showed that radio-loud quasars can become radio-quiet. Exploring the analogy between galactic nuclei and X-ray binaries (XRB), we pointed out there that this transition in quasars could be identified with a switch from low/hard to high/soft state in microquasars. Here, we present the evidence that traces of past occurrences of this kind of phenomena can be found in normal but once active galaxies. Based on the properties of a few such "post-active" galaxies that are representative for a much wider group, it has been argued that they have reached the evolutionary stages when their nuclei, which were radio-loud in the past, now, mimicking the behaviour of XRBs, remain in the intermediate state on their way towards quiescence or even have already entered the quiescent state. It follows that the full evolutionary track of XRBs can be mapped onto the evolution of galaxies. The above findings are in line with those reported recently for IC 2497, a galaxy that 70,000 years ago or less hosted a quasar but now appears as a normal one. This scenario stems from the presence of Hanny's Voorwerp, a nebulous object in its vicinity excited by that QSO in the epoch when IC 2497 was active. The post-active galaxies we deal with here are accompanied by extremely weak and diffuse relic radio lobes that were inflated during their former active period. These relics can be regarded as radio analogues of Hanny's Voorwerp.

“Forget it, let’s go with a handshake”: contracting practices of exporting small to medium size enterprises (SMEs)

description: Purpose: This paper aims to dissect cross-border contracting practices among exporting businesses. The under-representation of exporter-importer dynamics and the superficial understanding of contracts are the motivation for this exploratory study. Design/methodology/approach: The qualitative multiple case study design focuses on 18 small to medium size enterprise (SMEs) exporting from New Zealand. The analysis encompasses coding, pattern matching and explanation building. This paper uses coding to uncover themes and pattern matching/cross-case comparison to facilitate explanation building. Findings: The paper underlines the scant use of formal international sales/distribution contracts, the lack of knowledge concerning contracting, barriers to contract formation, misgivings about the court system and litigation and the adoption of proxy contracts. This paper depicts varieties of contracting practices, namely, no formal contract, improvisational, normative, and formal contractual arrangements and underlines the context in which each approach applies. Research limitations/implications: Similar to most studies in this area, the dissection of contracting practices derives from the exporter side of the dyad. This robs the research of a holistic view of the exchange. Nonetheless, this paper contributes to a better understanding of contract formation and formalization and to the role of context in shaping the activities of exporting SMEs. Practical implications: Although formal contracts are vital, they are not obligatory in all exchanges. Contracts matter more for high intensity exporters with comparatively short relationship histories, selling knowledge-intensive products in predominantly non-relational cultures. Policymakers should highlight the importance of contracts in such contexts and direct SMEs to several freely available resources on cross-border contracting. Social implications: The research casts fairness/equity and access to justice as pertinent structural disadvantages impacting the contracting practices of exporting SMEs. Originality/value: According to the authors’ knowledge, this paper is among the first studies to provide an in-depth portrayal of the contracting practices of exporting SMEs, to detail the pervasiveness of non-contractual contracting practices and to depict contracting as nuanced and context-dependent.

We show that, with suitable unitary transformations, the order parameter for the ground state can be reduced to only two non-vanishing complex components. The ground state has a large degeneracy. We find that while some Goldstone modes have linear dispersions, others are quadratic at low frequencies. We compare our results with the case of SU(N).

description:
Migration of neptunium, i.e. 237Np, a minor component of high-level nuclear waste, is in focus regarding the safety of nuclear waste disposal sites due to its long half-life and radiotoxicity. Opalinus Clay, the preferred host rock in Switzerland and also an option in Germany, is regarded as a reference formation with diffusion as the dominant transport process additionally retarded by sorption. One-dimensional diffusion simulations are conducted with PHREEQC to quantify neptunium migration. Sorption on clay minerals is integrated using surface complexation models. Numerical simulations are based on two diffusion experiments with the same setup, but one order of magnitude difference in transport parameters attributed to the core samples which stem from different rock facies. In the laboratory experiments, Np(V) was applied via a synthetic oxygen free pore water with neutral pH. The redox conditions are controlled by pyrite, while the pH of the system is buffered by calcite. The experiment of Fröhlich et al. (Radiochimca Acta, 2013, 101, 553-560) defined the numerical setup applied to the experiment of Wu et al. (Environmental Science & Technology, 2009, 43, 6567-6571). Our results indicate that neptunium migration is mainly controlled by pyrite oxidation and the associated reduction of Np(V) to Np(IV), while clay mineral quantities have only a minor impact. Since neptunium speciation and hence migration is very sensitive to oxidation and reduction reactions, redox conditions need to be accurately controlled and monitored in the laboratory if transport parameters are determined to be applied in the context of safety assessments.

description:
The seafloor functions as a substantial long-term (>100 yr) carbon sink and reservoir in the form of sedimentary organic particles. Human activities can modify the seafloor's natural carbon sequestration capacity by disturbing the upper sediment layers and thereby altering biogeochemical processes and releasing previously trapped carbon. Yet, the overall magnitudes of the changes in sedimentary carbon pools induced by these processes are not well known and could not be adequately considered in environmental impact assessments so far.

In this study, we quantify anthropogenic disturbances of sedimentary carbon sequestration in the North Sea using a combination of measurement data and numerical modeling. In particular, we examine the effects of bottom-contacting fisheries, sediment extraction, and material dumping. By resolving spatial and temporal patterns of both natural and anthropogenic drivers, we identify areas particularly vulnerable to degradation, representing the most detailed large-scale estimates of human impacts on North Sea sediments to date. Our results indicate that while the impacts of human activities on sedimentary carbon sequestration are comparable in magnitude to natural sedimentation processes, the resulting carbon benefits are considerably lower than previously estimated.

Although remaining uncertainties need to be further confined and missing processes such as ecosystem feedbacks considered, our findings can serve as a useful basis for the consideration of sedimentary carbon disturbance in the context of marine spatial management plans.
Arc melting of silicon doped boron carbide
Creators: name: Pásara, Alex Martín
Publisher: name: No Publisher Supplied
Year: 2023

description: Boron carbide is highly sought after for usage within ballistic armors as it is known for its low density as well as its high hardness. In order to improve boron carbide’s impact response, and thus increase its usability within the field, many projects have centered around additives to improve the properties of the boron carbide. Boron/silicon co-doping has been used to strengthen the crystal structure of the boron carbide and prevent the amorphization caused by high-strain-rate events. Herein, the arc melt processing technique is utilized to improve the fracture behavior of boron carbide. In this process, boron carbide has been mixed with different silicon-containing additives that are then arc melted wherein a single, chemically varying ingot is formed. The ingot is then crushed and milled into a fine powder and spark-plasma sintered into dense bulks. The final product is a dense silicon-doped boron carbide bulk whose microstructure can be further refined.Calibration of SEM-EDS for quantification of Si, B, and C was carried out and its viability demonstrated. The method used herein may serve as a process by which standards for other materials can be created. Formation of high-purity (93wt.%) SiB6 can be performed in a lab-setting by heating in argon environment to 1430°C. Initial doping using pure boron and pure silicon powders via arc melting proved to yield an average dopant level of 2.56at.% Si. Three sources of SiB6 were also used to compare to the Si/B co-doping method: commercial SiB6, in-house SiB6, and SiB6 formed in-situ alongside boron carbide. The Si/B co-doping resulted in the highest doping of the boron carbide grains prior to sintering, outperforming all three forms of SiB6. Of the SiB6 sources, a peak doping of 2.35at.% Si was achieved by the in-situ formation method. This is attributed to the higher amount of unreacted silicon (12wt%) present within sampled made in this way. Oxidation of the resultant materials were kept to a minimum as the arc melting process volatilizes any oxides present. This form of processing enables the improvement of already incredible material properties whilst also making it possible to do so using cost effective materials. It also eliminates the need for pre-reaction steps that have been shown to introduce unwanted phases and oxides into the final product.

description:
South Harz Potash Limited (SHP) is a publicly listed company on the Australian Securities Exchange (ASX). Through its wholly-owned subsidiary Südharz Kali GmbH, the Company holds the Ohmgebirge mining licence in the north-western part of the Thuringian Basin, a region with more than 100 years of history of mining Permian potash deposits.

Based on the available historical exploration data, the potash resource at the Ohmgebirge was categorised by Micon International Co Limited in 2019 as an Inferred Mineral Resource in accordance with the guidelines of the Australasian JORC Code (2012).

In order to increase the level of geological knowledge and the confidence in the existing drill hole and assay database and to advance the project, two confirmation holes were drilled in 2022. The successful drilling demonstrated a good comparability of lithostratigraphic, mineralogical and geochemical data with the historic exploration data. Combining the existing and new data sets, the geological model has been updated, allowing an upgrade of a substantial proportion of the Ohmgebirge Mineral Resource estimate from the Inferred to the Indicated classification.

Currently, SHP is collaborating with experienced consultants to prepare a feasibility study which will consider all relevant technical, economic, social and environmental aspects of the project in order to transform the Mineral Resource to a Mineral Reserve according to JORC (2012). To increase awareness of the importance of mining local raw materials, we communicate transparently and regularly with the regional public and all stakeholders on our project advancements.

This functional motivates a stability inequality which plays an important role in questions concerning the regularity of Ricci-flat spaces and the non-uniqueness of the Ricci flow with conical initial data. In the second part, we define a geometric invariant lambda_AF for asymptotically flat manifolds with nonnegative scalar curvature. This invariant gives a quantitative lower bound for the ADM-mass from general relativity, motivates a Ricci flow proof of the rigidity statement in the positive mass theorem, and eventually leads to the discovery of a mass decreasing flow in dimension three.

description: Purpose: The purpose of this study is to organize and assess knowledge on the capabilities pertinent to the early internationalization of born globals (BGs) and international new ventures (INVs). Design/methodology/approach: A systematic approach is used to search, code, organize and synthesize 155 peer-reviewed journal articles on capabilities and early internationalization. Findings: The study delimits eight operational and five dynamic capabilities. The synthesis links capabilities to three antecedents (i.e. firm specific factors, managerial socio cognitive attributes and market factors) and three outcomes (i.e. precocity, survival and performance). While 7 of the 12 linkages identified are well-established, relationships involving market factors, survival and dynamic capabilities are sparsely researched. Research limitations/implications: The authors know more about the effects of firm specific factors and managerial socio cognitive attributes on operational and dynamic capabilities than we do the influence of market factors on either group of capabilities. Likewise, the authors know more about the influence of operational and dynamic capabilities on performance than we do their impact on precocity or survival. Practical implications: As the pandemic has shown, businesses with adaptable capabilities (e.g. shifting from a brick and mortar to an online/omnichannel approach or micro-breweries competent to switch from manufacturing beer to hand sanitizer) have increased their chance of survival while helping society cope. Originality/value: This to the authors’ knowledge is the first study to provide a comprehensive review of literature on the nebulous concept of capabilities, in the context of the burgeoning research stream on early internationalization.

description:
The evolution of terrestrial life was as profoundly affected by the end-Permian mass extinction as life in the sea. The recovery of life in the Triassic represented much more than simply a return to pre-extinction conditions, but in fact an entirely new world was ushered in. The generalized replacement of synapsids by archosauromorph reptiles had long been recognized, together with the rise of the dinosaurs to ecological dominance and origins of many modern groups including lissamphibians, turtles, lizards, crocodilomorphs, and mammals. In addition, all the new larger tetrapods had switched from a sprawling posture before the crisis to an erect posture and parasagittal gait afterwards, and this hints at higher activity levels. This is confirmed by the more recent discovery that many of the Triassic archosauromorphs had indicators of endothermy (warm-bloodedness) in their bone histology, and that these Triassic tetrapods also had insulating dermal structures: hair in synapsids and feathers in dinosaurs, pterosaurs and their ancestors. All these indications of endothermy are debated and yet to be confirmed by further study, but they suggest an overall increase of energy in ecosystems, a general speeding up of life as competition and predation increased. Also, it means that these tetrapods were consuming more energy than their Permian forebears. In many ways, these discoveries suggest a macroevolutionary model equivalent to the Mesozoic Marine Revolution, in which Mesozoic marine life was more active and more meaty than much if Palaeozoic marine life.

title: Studies in the popularisation of science in England, 1800-1830
Creators: name: Kitteringham, G. S.
Publisher: name: University of Kent

description: The ideas of ordinary people about the nature and value of science have a profound effect upon both the practice and the reception of science. Despite this, little work has been done by historians on the development and characteristics of such ideas. One important process affecting this development was the popularisation of science, which is studied in this thesis in England during the first three decades of the nineteenth century. The major subdivisions of the thesis are based upon the various media of popularisation. After an introductory chapter which discusses the place of science in society, the nature of popularisation, and eighteenth-century popularisation, chapters two and three analyse popular science books. The coverage of science is related to contemporary social groupings and four representative sciences (natural history, geology, chemistry and astronomy) are examined in detail. Chapter four discusses science coverage in both scientific and general periodicals. The subsequent three chapters examine the roles of societies and institutions in the popularisation of science. The local variations in these activities are taken into account by analysing London and provincial societies separately, but the common characteristics of many mechanics' institutions are recognised and the institutes are considered together in chapter seven. Chapter eight restates and discusses the major conclusions of the study. Popularisation is shown to have been not merely the simple dissemination of scientific truths. The means of popularisation and even the very content of popular science are shown to have varied with the desires and beliefs of the popularisers about both the natural and the social worlds. Similarly, the audiences for popular science displayed varying degrees of receptivity to these ideas, dependent upon their social positions and interests.

description: The structure of baryon resonance in coupled-channel meson-baryon scattering is studied from the viewpoint of chiral dynamics. The meson-baryon scattering amplitude can be successfully described together with the properties of the resonance in the scattering, by implementing the unitarity condition for the amplitude whose low energy structure is constrained by chiral theorem. Recently, there have been a major progress in the study of the structure of the resonance in chiral dynamics. We review the methods to clarify the structure of the resonance by focusing on the Lambda(1405) resonance.

On the properties of discs around accreting brown dwarfs

description: We present a grid of models of accreting brown dwarf systems with circumstellar discs. The calculations involve a self-consistent solution of both vertical hydrostatic and radiative equilibrium along with a sophisticated treatment of dust sublimation. We have simulated observations of the spectral energy distributions and several broadband photometric systems. Analysis of the disc structures and simulated observations reveal a natural dichotomy in accretion rates, with \logmdot $>-$9 and $\leq -$9 classed as extreme and typical accretors respectively. Derivation of ages and masses from our simulated photometry using isochrones is demonstrated to be unreliable even for typical accretors. Although current brown dwarf disc candidate selection criteria have been shown to be largely reliable when applied to our model grid we suggest improved selection criteria in several colour indices. We show that as accretion rates increase brown dwarf disc systems are less likely to be correctly identified. This suggests that, within our grid, systems with higher accretion rates would be preferentially lost during brown dwarf target selection. We suggest that observations used to assert a $\dot{M}\propto M_*^2$ relationship may contain an intrinsic selection bias.

description:
The hydrology and hydrogeology of the German Lusatian mining district has strongly been impacted by open pit lignite mining. During active mining, mines are dewatered to lower the groundwater tables below the coal-bearing layers (up to 100 m below the surface). Following the phase-out of current mining activities, groundwater levels will rise and groundwater will reconnect with surface water. The groundwater-surface water interactions strongly influence flow patterns and dynamics as well as hydrochemistry and water quality, and are still largely unknown.

It is therefore planned to systematically select up to five representative post-mining lakes to conduct detailed measurement of climatological parameters and stable isotopes (deuterium, oxygen-18, and sulphur-34). The overall goal of this work (IsoGon project) is the characterization of surface water-groundwater interactions and the quantification of evaporation losses from the post-mining lakes in Lusatia. In this contribution, we summarize our planned project activities, state of the project, current understanding of the subject and our objectives of further planned work.
