description: Large amounts of carbon are stored in permafrost-affected soils of the Arctic tundra. The quantity, distribution and composition of this carbon are important, because much of the carbon is likely to be released as a result of global warming. We have studied soils of the central Siberian Arctic to determine the carbon content and the nature of the organic matter by density fractionation, and 13C-NMR- and 13C-stable-Isotope analyses. There are pronounced differences in the profile and variations from place to place in the quantity and nature of soil organic matter. We estimated that the mean stock of carbon was 14.5 kg m-2 within the active layer. We found a total of about 30.7 kg C m-3 in the entire upper metre of the soils. Carbon of the tussock tundra showed strong vertical differentiation, with a large proportion comprising decomposed, recalcitrant compounds. We identified within the soil several zones of aerobe and anaerobe decomposition. Mobile carbon fractions have precipitated under the influence of low temperatures.

title: Novel Fluorescent Sensors for the Detection of Organic Molecules in Extraterrestrial Samples
Creators: name: Adkin, Roy
Publisher: name: The Open University
Year: 2019

description: The objective of this PhD project was to develop, test and evaluate lanthanide-based fluorescent sensors that could detect organic molecules in extracts taken from carbonaceous chondrite-type meteorites. These contain solvent soluble organic molecules, some of which are potentially prebiotic and are, therefore, of interest in the search for extinct or extant life in extraterrestrial environments. The sensors are based upon the ligands DOTA and DO3A, the lanthanide complexes of which are well characterised and have been used as contrast agents and sensors in medical and biological sectors. Their application to the extracts of geological samples, and subsequent analysis by fluorescence spectroscopy, is, however, novel. After testing on individual analytes, it was shown that nucleobases and benzoic acid modified the intensity of the lanthanide emissions and modified the form of the emission spectrum of europium by sensitisation of certain transitions. The presence of these analytes affected the spectra of the DO3A lanthanide complexes more effectively, therefore, novel, structurally similar DO3A-like ligands were synthesised, chelated to lanthanides and tested. Sensors were tested with individual analytes, solution obtained from weathered mineral samples, a terrestrial rock and two carbonaceous chondrites (Murchison and ALH88045). Tests concluded that the presence of dissolved mineral species or mineral particulates in an extract would be unlikely to interfere with sensor responses. When applied to the extracts of the terrestrial and extraterrestrial rocks, the sensor responses were varied and, by comparing them to responses recorded when in the presence of individual analytes, indicated that the sensors detected the presence of structurally similar molecules. Therefore, it can be concluded that the sensors tested exhibit potential utility for analyte detection in a variety of scenarios. Using fluorescence techniques, perhaps as a ‘lab-on-a-chip’ device as part of the instrumentation on board a rover on the surface of planetary body, these sensors may be employed in the ongoing quest to detect evidence of alien life and clues as to how life began on Earth.
Closed-form Solutions for an Explicit Modern Ideal Tontine with Bequest Motive

description: In this paper I extend the work of Bernhardt and Donnelly (2019) dealing with modern explicit tontines, as a way of providing income under a specified bequest motive, from a defined contribution pension pot. A key feature of the present paper is that it relaxes the assumption of fixed proportions invested in tontine and bequest accounts. In making the bequest proportion an additional control function I obtain, hitherto unavailable, closed-form solutions for the fractional consumption rate, wealth, bequest amount, and bequest proportion under a constant relative risk averse utility. I show that the optimal bequest proportion is the product of the optimum fractional consumption rate and an exponentiated bequest parameter. I show that under certain circumstances, such as a very high bequest motive, a life-cycle utility maximisation strategy will necessitate negative mortality credits analogous to a member paying life insurance premiums. Typical scenarios are explored using UK Office of National Statistics life tables.

We present detailed Monte Carlo results for the nonconserved random-bond Ising model, which are consistent with power-law growth with a variable exponent. These results are interpreted in the context of disorder barriers with a logarithmic dependence on the domain size. Further, we clarify the implications of logarithmic barriers for both nonconserved and conserved domain growth.

description: Electronic flat bands in momentum space, arising from strong localization of electrons in real space, are an ideal stage to realize strong correlation phenomena. In certain lattices with built-in geometrical frustration, electronic confinement and flat bands can naturally arise from the destructive interference of electronic hopping pathways. Such lattice-borne flat bands are often endowed with nontrivial topology if combined with spin-orbit coupling, while their experimental realization in condensed matter system has been elusive so far. Here, we report the direct observation of topological flat bands in the vicinity of the Fermi level in frustrated kagome system CoSn, using angle-resolved photoemission spectroscopy and band structure calculations. The flat band manifests itself as a dispersionless electronic excitation along the G-M high symmetry direction, with an order of magnitude lower bandwidth (below 150 meV) compared to the Dirac bands originating from the same orbitals. The frustration-driven nature of the flat band is directly confirmed by the real-space chiral d-orbital texture of the corresponding effective Wannier wave functions. Spin-orbit coupling opens a large gap of 80 meV at the quadratic band touching point between the Dirac and flat bands, endowing a nonzero Z2 topological invariant to the flat band in the two-dimensional Brillouin zone. Our observation of lattice-driven topological flat band opens a promising route to engineer novel emergent phases of matter at the crossroad between strong correlation physics and electronic topology.

description: The influence of an axial through-flow on the spatiotemporal growth behavior of different vortex structures in the Taylor-Couette system with radius ratio eta=0.5 is determined. The Navier Stokes equations (NSE) linearized around the basic Couette-Poiseuille flow are solved numerically with a shooting method in a wide range of through-flow strengths Re and different rates of co- and counterrotating cylinders for toroidally closed vortices with azimuthal wave number m=0 and for spiral vortex flow with m=+1 and m=-1. For each of these three different vortex varieties we have investigated (i) axially extended vortex structures, (ii) axially localized vortex pulses, and (iii) vortex fronts. The complex dispersion relations of the linearized NSE for vortex modes with the three different m are evaluated for real axial wave numbers for (i) and over the plane of complex axial wave numbers for (ii,iii). We have also determined the Ginzburg-Landau amplitude equation (GLE) approximation in order to analyze its predictions for the vortex stuctures (ii,iii). Critical bifurcation thresholds for extended vortex structures are evaluated. The boundaries between absolute and convective instability of the basic state for vortex pulses are determined with a saddle-point analysis of the dispersion relations. Finally, the linearly selected front behavior of growing vortex structures is investigated. For the two front intensity profiles (increasing in positive or negative axial direction) we have determined front velocities, axial growth rates, and the wave numbers and frequencies of the unfolding vortex patterns with azimuthal wave numbers m=0, +1, -1, respectively.

title: Unravelling the Complexity of the Molecular and Physiological Response to Environmental Change in Seagrasses
Creators: name: Ruocco, Miriam
Publisher: name: The Open University
Year: 2019

description: This thesis explores the complexity of seagrass stress response in the face of current environmental changes. This is a timely and relevant issue due to the role supplied by these foundation species in coastal ecosystems, and the dramatic consequences their loss would cause on marine biodiversity and human well-being.

 Using as target species the iconic Mediterranean seagrass Posidonia oceanica, here I show: i) how molecular reprogramming, acting primarily at gene-expression level, coordinates physiological and morphological responses to different stressors, and ultimately determines species’ acclimation strategies and tolerance capacity; ii) the differential stress response existing within and among different organs, and between different shoot types; iii) how the response to a single stressor can be modified depending on its temporal variability, and due to the interaction with another stressor.

 In this study, new transcriptome data have been generated, from leaves and shoot-apical meristems, increasing considerably molecular resources available for future studies on seagrass evolutionary ecology and functional genomics. Moreover, this research sheds first light on the stress response of organs other than leaf, in seagrasses, and recognises the shoot meristem as a key determinant of whole plant survival. Common and stress-specific molecular biomarkers have been identified through different approaches, and their potential applicability as sub-lethal stress indicators can be verified in the future with ad hoc experiments.

 Another important aspect of this study is the recognition of the importance of epigenetic variations, specifically DNA methylation changes, as key mechanisms for phenotypic accommodation and adaptive responses to environmental changes in seagrasses. Tolerance capacity of the species to main current threats of coastal areas, namely the reduction of available light, heat stress, eutrophication and herbivory, is discussed in light of the results obtained from the different experiments.

description: Auf den mittelpleistozänen fluvioglazialen Terrassen der Traun-Enns-Platte in der Region um Wels (Oberösterreich) wurden drei Löss-/Paläobodensequenzen untersucht. Jedes dieser Profile ist für mittelpleistozäne Abfolgen im nordöstlichen Alpenvorland charakteristisch. Die Profile umfassen mächtige Pedokomplexe, welche eine Differenzierung und Einstufung von interglazialen Paläoböden erlauben. Die Löss-/Paläobodensequenz von Oberlaab ist auf der fluvioglazialen Terrasse des Mindel-Glazials im klassischen Sinne entwickelt (Jüngere Deckenschotter) und weist vier interglaziale Paläoböden auf. Diese Tatsache macht eine Einstufung der Jüngeren Deckenschotter mindestens in die fünftletzte Kaltzeit wahrscheinlich (MIS 12). Die Deckschichten auf den Günz-Deckenschottern im klassischen Sinn (Ältere Deckenschotter) beinhalten fünf Paläoböden. Beide Lokalitäten weisen eine sehr intensive Pedogenese in ihrem basalen Pedokomplex auf, die wesentlich ausgeprägter ist, als in den überlagernden Paläoböden. Die pedostratigraphischen Ergebnisse lassen eine Einstufung der Älteren Deckenschotter mindestens ins MIS 16 zu.

description: Die Frage, die im Rahmen der Aktionsforschung untersucht wurde, lautete: „Inwiefern verbessern sich die Schreib- und Textkompetenzen von Oberstufenschülerinnen und -Schülern der Basisklassen, wenn sie adaptive, natürlich differenzierte und prozessorientierte Lern- und Förderangebote anwenden?“ Die Förderung basaler und hierarchiehöherer Schreibkompetenzen stand im Zentrum des Praxisprojektes. Die Vermittlung expliziter Schreibstrategien, die sich am revidierten Schreibmodell von Hayes et.al. (1996) orientiert, wurde in einem schülerzentrierten, entdeckenden Unterricht erprobt, diskutiert und eingeübt. Die Analyse der individuellen Textprodukte ergab, dass viele Jugendliche ihren Text qualitativ verbessern konnten und eine Kompetenzerweiterung im Schreiben stattgefunden hat. Die Daten und die kommunikative Validierung belegen, dass die Konzeption des Praxisprojektes insgesamt positiv bewertet wurde.

description: The event horizon of a black hole in general relativity absorbs all infalling radiation. Any observation of the contrary would immediately challenge the expectation that astrophysical black holes are described by the vacuum Kerr geometry. If a putative black hole does reflect part of the ingoing radiation, its quasinormal mode structure is drastically altered. Low frequency modes can be introduced that are resonantly excited during the inspiral of a binary system. We study the resulting phase shift of the gravitational wave signal. Building on neutron star results, we obtain a model-independent expression for the phase shift that depends only on quasinormal modes and Love numbers of the compact object. We find that the phase shift might be detectable with Einstein Telescope for asymmetric binaries in high signal-to-noise events ($\sim 10^3$), but by far cannot explore the Planck scale.

description: A great deal of research has been presented on the application of activity-based costing (ABC) in the manufacturing and service industries. In the field of agribusiness, which focuses uniquely on joint products, few studies exist that illustrate applications of ABC. This research has therefore applied ABC to a food company, concentrating on fresh and frozen chicken processing production. The basic process of ABC, based upon five steps, was applied and demonstrated the difficulties in applying cost data collection, identifying activity and cost drivers, as well as collecting driver data. The results also revealed significant differences in unit costs derived by ABC and the company’s existing cost system, particularly within frozen food products. This may suggest the possibility of distorted cost allocations within the company’s current costing system.

description: The increasing number of food contamination events has called the attention of both practitioners and scholars to food safety problems and their consequences. Many of these events are related to the supply chain because food production is now a global process of commoditized goods, made by large corporations that purchase inputs from producers in many countries. Given the linkage between supply chain and food safety issues, we investigated how studies in the supply chain management area have examined food safety issues, exploring some of their important characteristics. To do so, we conducted a systematic literature review of 46 papers, published in 23 journals, indexed in the Web of Science database. As a result, we pointed out some main characteristics of these papers, including journal attributes, authorship data, citation network, methodological characteristics, and theoretical approaches. Results serve as a reference to scholars and allow us to discuss some potential opportunities for future research in the field of food safety in the supply chain management area.

description: The increasing trend of food scandal crises is not well followed in recent studies of spatial price transmission. This paper analyses the impact on the domestic market of an Aflatoxin M1 outbreak in the Serbian dairy sector during 2013/2014 using a spatial price transmission approach. Monthly farm milk prices in Serbia for the period 2007/2014 were contrasted with leading dairy exporting countries New Zealand, USA and Germany, which did not have a food scare in their dairy sectors. To estimate the impacts a Markov-switching vector error-correction model was utilized. For all four dairy markets the model identified two price change regimes: standard and extreme. Although it was predictable, an extreme regime was not identified during the Aflatoxin M1 crises in Serbia because of some specific characteristics of its dairy production. The results suggest that the Aflatoxin M1 outbreak ‘froze’ the Serbian dairy market and temporally disconnected it from the world milk market. Farmer’s prices fell below their long-run equilibrium levels. The total loss of the Serbian farm-level dairy sector during the crisis reached up to 96.2 million EUR. These ‘missed opportunity’ significantly slowed investment in the dairy sector.

Traces of the bone-eating annelid Osedax in Oligocene whale teeth and fish bones

Publisher: name: Springer-Verlag
Year: 2012

description: The range of substrates that the bone-eating marine worm Osedax is able to consume has important implications for its evolutionary history, especially its potential link to the rise of whales. Once considered a whale specialist, recent work indicates that Osedax consumes a wide range of vertebrate remains, including whale soft tissue and the bones of mammals, birds and fishes. Traces resembling those produced by living Osedax have now been recognized for the first time in Oligocene whale teeth and fish bones from deep-water strata of the Makah, Pysht and Lincoln Creek formations in western Washington State, USA. The specimens were acid etched from concretions, and details of the borehole morphology were investigated using micro-computed tomography. Together with previously published Osedax traces from this area, our results show that by Oligocene time Osedax was able to colonize the same range of vertebrate remains that it consumes today and had a similar diversity of root morphologies. This supports the view that a generalist ability to exploit vertebrate bones may be an ancestral trait of Osedax.

description: We find an interesting connection between perturbative large N gauge theory and closed superstrings. The gauge theory in question is found on N D3-branes placed at the tip of the cone R^6/Gamma. In our previous work we showed that, when the orbifold group Gamma breaks all supersymmetry, then typically the gauge theory is not conformal because of double-trace couplings whose one-loop beta functions do not possess real zeros. In this paper we observe a precise correspondence between the instabilities caused by the flow of these double-trace couplings and the presence of tachyons in the twisted sectors of type IIB theory on orbifolds R^{3,1}x R^6/Gamma. For each twisted sectors that does not contain tachyons, we show that the corresponding double-trace coupling flows to a fixed point and does not cause an instability. However, whenever a twisted sector is tachyonic, we find that the corresponding one-loop beta function does not have a real zero, hence an instability is likely to exist in the gauge theory. We demonstrate explicitly the one-to-one correspondence between the regions of stability/instability in the space of charges under Gamma that arise in the perturbative gauge theory and in the free string theory. Possible implications of this remarkably simple gauge/string correspondence are discussed.

description: Introduction Inter-specific comparisons of metazoan developmental mechanisms have provided a wealth of data concerning the evolution of body form and the generation of morphological novelty. Conversely, studies of intra-specific variation in developmental programs are far fewer. Variation in the rate of development may be an advantage to the many marine invertebrates that posses a biphasic life cycle, where fitness commonly requires the recruitment of planktonically dispersing larvae to patchily distributed benthic environments. Results We have characterised differences in the rate of development between individuals originating from a synchronised fertilisation event in the tropical abalone Haliotis asinina, a broadcast spawning lecithotrophic vetigastropod. We observed significant differences in the time taken to complete early developmental events (time taken to complete third cleavage and to hatch from the vitelline envelope), mid-larval events (variation in larval shell development) and late larval events (the acquisition of competence to respond to a metamorphosis inducing cue). We also provide estimates of the variation in maternally provided energy reserves that suggest maternal provisioning is unlikely to explain the majority of the variation in developmental rate we report here. Conclusions Significant differences in the rates of development exist both within and between cohorts of synchronously fertilised H. asinina gametes. These differences can be detected shortly after fertilisation and generate larvae of increasingly divergent development states. We discuss the significance of our results within an ecological context, the adaptive significance of mechanisms that might maintain this variation, and potential sources of this variation.

description: Traditional tax administration can no longer be sustained in the present IT powered environment that most organizations operate in. This study is set to examine forensic accounting as tool for effective tax administration in Nigeria with Edo State in focus. The specific objectives are to examine the impact of forensic tax assessment and forensic tax audit on tax administration in Edo State.  Survey research design was adopted and a sample of 347 questionnaires was distributed to tax practitioners and staff both Federal and State revenue services operating in Benin-City Edo State. Simple percentages, tables were used to analyze the data while regression analysis was used to test the hypothesis. The outcome of the findings shows that there is positive and significant relationship between forensic tax assessment and forensic tax audit on tax administration in Nigeria.  The study concluded that there is positive and significant relationship between forensic accounting and tax administration in Edo State. The study therefore recommends that all tax authorities both at Federal and state level should engage the services of forensic accountants in their offices to curb the spate of tax fraud that has adversely affected tax revenue generated.

description: Stereo-chemically active lone pairs are typically described as an important non-bonding effect, and large interest has centered on understanding the derived effect of lone pair expression on physical properties such as the thermal conductivity. To manipulate such properties, it is essential to understand the conditions that lead to lone pair expression and to provide a quantitative chemical description. Here we first use density functional theory calculations to establish the presence of stereo-chemically active lone pairs on antimony in $\text{MnSb}_{2}\text{O}_{4}$. The lone pairs are formed through a similar mechanism to those in binary post-transition metal compounds in an oxidation state of two less than their main group number, where the degree of orbital interaction determines the expression of the lone pair. In $\text{MnSb}_{2}\text{O}_{4}$ the Sb lone pairs interact through a void space in the crystal structure, and they minimize their mutual repulsion by introducing a deflection angle. This angle increases significantly with decreasing Sb-Sb distance, thus showing the highly destabilizing nature of the lone pair interactions. Analysis of the chemical bonding in the structure shows that it is dominated by polar covalent interactions. A database search of related ternary chalcogenide structures shows that for structures with a lone pair the degree of lone pair expression is largely determined by whether the antimony-chalcogen units are connected or not, suggesting a cooperative effect. Isolated $\text{SbX}_3$ units have larger X-Sb-X bond angles, and therefore weaker lone pair expression than connected units. Since increased lone pair expression is equivalent to an increased orbital interaction (covalent bonding), which typically leads to increased heat conduction, this can explain the previously established correlation between larger bond angles and lower thermal conductivity.

description: The United States has surpassed Iran as the largest pistachio exporter to the European Union. Both lower prices and a less frequency of aflatoxin contamination have contributed to the success of the US pistachio industry. Using EU monthly imports and food safety alerts data, we estimate EU demand for US and Iranian pistachios. We find that EU demand for US pistachios is price-inelastic but the demand for Iranian pistachios is price-elastic. We also find that the income effect is positive for US nuts but negative for Iranian nuts. Most importantly, we find that EU imports of US pistachios decrease with aflatoxin alerts traced back to the US but increase with contamination incidents originated from Iran.
Theory Meets Reality: Testing Accretion Disc Models with LMC X-3 and GRO J1655-40

description: We present a detailed investigation of X-ray spectral models used to fit the thermal accretion disc emission in black-hole X-ray binaries. To explore the nature of the accretion disc in strong gravitational fields via non-relativistic and relativistic disc models, we fit ~2000 RXTE observations of GRO J1655-40 and LMC X-3. We find that the non-relativistic multi-colour disc blackbody model (diskbb) gives significantly (about ~50-60%) higher values for disc temperatures and lower (often unphysical) inner disc radii than relativistic disc models. We find that this difference in the disc temperature and inner disc radius cannot be explained by only varying spectral hardening factor and varying inner disc radius in combination with relativistic treatment of the disc is a more probable explanation for the previously reported deviations in the L-T relationship in a subset of black hole X-ray binaries. Our study clearly shows the importance of self-consistent modeling of the thermal emission in accreting compact objects, especially when estimating the black hole spin with the continuum-fitting method.

description: Traditional foods are facing new market challenges tied to current trends in food habits and their determinants, such as the decline of domestic food preparation, the increased demand for convenience foods, the increasing importance of industrial food production, and the evolution of regulations on food safety. In this context our study aims at improving the knowledge of consumer segments in traditional foods market in order to develop better marketing strategies. The preferences for different credence attributes are investigated applying a latent class choice model to the extra-virgin olive oil market in Italy. Results show the existence of a marked heterogeneity of preferences, which determines the presence of both vertical and horizontal differentiation of the product.

description: In Uruguay commercial granite varieties comprise mafic rocks, granitoids, and syenitoids. There is a long tradition in Uruguay, as well as worldwide, of using dimensional stones in architecture and art, specially granitic ones. Some of the present applications of these dimensional stones are as façade cladding, countertops, and outdoor and indoor floor slabs. The color spectrum of the Uruguayan granitic dimensional stones varies from black to light gray, covering a wide variety of red and pink and minor greenish-gray. The décor of these granitic dimensional stones is mainly determined by their fabric, fundamentally the grain size and the color distribution between the different minerals that compose the rocks. In the present research the most important commercial granites were sampled to analyze their petrography and petrophysical properties. A detailed structural analysis has been performed in several deposits, as well as the application of the software 3D Block Expert for modeling the possible raw block size distribution. Other factors controlling the mining viability of the deposits were also studied (e.g., homogeneity/heterogeneity of color and décor) and the possible reserves were calculated.
Water masers in dusty environments

description: We study in details a pumping mechanism for the lambda=1.35 cm maser transition 6_16 -> 5_23 in ortho-water based on the difference between gas and dust temperatures. The upper maser level is populated radiatively through 4_14 -> 5_05 and 5_05 -> 6_16 transitions. The heat sink is realized by absorbing the 45 mum photons, corresponding to the 5_23 -> 4_14 transition, by cold dust. We compute the inversion of maser level populations in the optically thick medium as a function of the hydrogen concentration, the gas-to-dust mass ratio, and the difference between the gas and the dust temperatures. The main results of numerical simulations are interpreted in terms of a simplified four-level model. We show that the maser strength depends mostly on the product of hydrogen concentration and the dust-to-water mass ratio but not on the size distribution of the dust particles or their type. We also suggest approximate formulae that describe accurately the inversion and can be used for fast calculations of the maser luminosity. Depending on the gas temperature, the maximum maser luminosity is reached when the water concentration N_water ~ 10^6-10^7 cm^-3 times the dust-to-hydrogen mass ratio, and the inversion completely disappears at density just an order of magnitude larger. For the dust temperature of 130 K, the 6_16 -> 5_23 transition becomes inverted already at the temperature difference of Delta T ~1 K, while other possible masing transitions require a larger Delta T > 30 K. We identify the region of the parameter space where other ortho- and para-water masing transitions can appear.

Nd–Sr–Hf–O isotope provinciality in the northernmost Arabian–Nubian Shield: implications for crustal evolution

description: Multi-isotope study including whole-rock Nd–Sr, single zircon Hf, and SIMS δ18O analyses of zircons sheds light on magma sources in the northernmost Arabian–Nubian Shield (ANS) during ~820–570 Ma. Reconnaissance initial Nd and Sr isotope data for the older rocks (~820–740 Ma) reaffirms previous estimates that early crustal evolution in this part of the shield involved some crustal contamination by pre-ANS material. Prominent isotope provinciality is displayed by post-collisional calc-alkaline and alkaline igneous rocks of ~635–570 Ma across a NW-SE transect across basement of the Sinai Peninsula (Egypt) and southern Israel. Silicic rocks of the NW-region are characterized by lower εNd(T)–εHf(T) and higher Sri and δ18O compared with rocks of the SE-region, and the transition between the regions is gradual. Within each region isotope ratios are independent of the extent of magma fractionation, and zircon cores and rims yield similar δ18O values. Comparison with southern segments of the ANS shows that the source for most ~635–570 Ma rocks can be modeled as the isotopically aged lower-intermediate crust in the ANS core (SE-region) and its northern, more contaminated ANS margins (NW-region). Nevertheless, Nd–Sr isotope enrichment of the lithospheric mantle is indicated by some basic magmas of the NW-region displaying the most enriched Nd–Sr isotope compositions. Comparison of Nd and Hf depleted mantle model ages for rocks of the SE-region may indicate that crustal formation events in the ANS geographical core took place at 1.1–1.2 Ga and were followed by crustal differentiation starting at ~0.9 Ga.
