description:
To relate Intraplate volcanism to upper mantle structure, we investigate small-scale structural-variations of the lithosphere-asthenosphere beneath the Circum-Mediterranean using regional high-resolution 3-D surface-wave tomography. The imaged low shear-wave velocities (Vs<4.2 km/s) between depths of ~70-300 km indicate the presence of nine shallow asthenospheric volumes (SAVs) across the Circum-Mediterranean upper mantle forming a partly interconnected belt and separated only by high velocity slabs and thickened lithosphere. Integrated geophysical-petrological modelling for 14 representative locations, yields estimates of the lithospheric thickness and the upper mantle geotherm and confirms the presence of thin lithosphere (<80 km) above areas of anomalously warm SAVs (>1300°C).

We distinguish between Intraplate, Mixed-origin and Subduction-related volcanism in the Circum-Mediterranean during the last 70 Ma and find a remarkable colocation between the SAVs and Cenozoic Intraplate and Mixed-origin volcanic provinces (IMVPs). Moreover, the lateral distance from any shallow asthenosphere to the closest neighboring volcanic province is, on average, as low as 100 km, with a maximum distance of 350 km, indicating a dense network of IMVPs above SAVs. By contrast, IMVPs are completely absent in areas of thick mantle lithosphere.

We relate origin of the SAVs either to asthenospheric upwelling caused by slab-rollback and back-arc extension (Aegean-Anatolian, Pannonian, Moesian, Western Mediterranean SAVs) or to thermal erosion of the lithosphere partly coupled with continental rifting (Adriatic, Central European, North African, Middle East SAVs), respectively. The oldest ages of the IMVPs in the Circum-Mediterranean indicate that the development of the current SAVs started at about ~60-70 Ma ago and accelerated in Neogene.

description: We consider a class of infinite-state stochastic games generated by stateless pushdown automata (or, equivalently, 1-exit recursive state machines), where the winning objective is specified by a regular set of target configurations and a qualitative probability constraint `>0' or `=1'. The goal of one player is to maximize the probability of reaching the target set so that the constraint is satisfied, while the other player aims at the opposite. We show that the winner in such games can be determined in PTIME for the `>0' constraint, and both in NP and coNP for the `=1' constraint. Further, we prove that the winning regions for both players are regular, and we design algorithms which compute the associated finite-state automata. Finally, we show that winning strategies can be synthesized effectively.

description: After a review of some critical issues about usage and energy efficiency in public buildings, the paper describes Planergy™, a service model which supports public administrations to monitor their buildings. The service, which is distributed through a web platform www.Planergy.it, represents an interesting social innovation since it directly involves workers and building users and since its results can be diffused as Open Data Sets. Its results can assist local administrators in developing a substantiated institutional communication and in adopting a sustainability reporting that takes into account both environmental and social consequences of their policies. Through the support of empirical data collected from its buildings, the administration can encourage specialists and firms in developing effective project proposals and it can motivate employees and the public towards energy efficiency good practices. In this way, an administration council can become a source of inspiration and good example to promote sustainable energy within its municipal area.

description: Use of herbicides needs to be properly managed to balance benefit of reducing harvest loss due to weeds against potential environmental risks. Precision weed control is expected to reduce the quantity of applied herbicide by better targeting the spraying. This can involve several components of weed control, ranging from strategic to tactic decision-making, up to equipment management. To this end we tested the coupling of a weed emergence predictive model (AlertInf) for spring row crops with mapping of early weed distribution. Our aim was to achieve both timely herbicide application and precise spatial weed distribution to ensure the highest herbicide efficacy. Airborne images produced by Unmanned Aerial Vehicles provides the best trade-off for retrieving the spatial distribution of the weed infested areas. Three series of images were acquired in early June 2019 over a maize field in the experimental farm of the University of Padova. Additional field surveys allowed to identify the presence of the target weed Sorghum halepense (L.) with an emergence percentage of 96%, according to the AlertInf model, at the date of the flight. Weed spatial distribution was assessed by the exploratory comparison of two algorithms: Artificial Neural Networks (ANN) performed within the SAGA software, and Visible Atmospherically Resistant Index (VARI) within ArcGIS Pro. Classification performances were trained and evaluated against a dataset issued from visual on-screen labelling three classes, i.e. crop, bare soil, weed. ANN provided more precise weed classification in respect to VARI, therefore VARI missed a part of infested area compared to ANN. Based on the technical specifications of different models of sprayers, several maps were created slitting the field into cells of 3m2, 2m2 and 0.25m2 and with three different thresholds for treatment decision depending on each cell infestation (i.e., >1%, >5% and >10% of pixel labelled as weed). Prescription maps showed that sprayed area potentially reduced from 42% to 87% using the ANN classification and from 65% to 93% at 1% using the VARI classification for pixel with 10% of cell infestation. Altogether, the results suggest that site-specific mapping informed on emergence models can enable a substantial herbicide reduction through both timely and site-specific weed control with ordinary section control sprayers. Further research is required to evaluate the contribution of a weed emergence model, such as AlertInf, to herbicide usage reduction, performing additional tests in different fields and including more weed species.

description: We present the results of a search for galaxy clusters in Subaru-XMM Deep Field. We reach a depth for a total cluster flux in the 0.5-2 keV band of 2x10^{-15} ergs cm^{-2} s^{-1} over one of the widest XMM-Newton contiguous raster surveys, covering an area of 1.3 square degrees. Cluster candidates are identified through a wavelet detection of extended X-ray emission. The red sequence technique allows us to identify 57 cluster candidates. We report on the progress with the cluster spectroscopic follow-up and derive their properties based on the X-ray luminosity and cluster scaling relations. In addition, 3 sources are identified as X-ray counterparts of radio lobes, and in 3 further sources, X-ray counterpart of radio lobes provides a significant fraction of the total flux of the source. In the area covered by NIR data, our identification success rate achieves 86%. We detect a number of radio galaxies within our groups and for a luminosity-limited sample of radio galaxies we compute halo occupation statistics using a marked cluster mass function. We compare the cluster detection statistics in the SXDF with the predictions of concordance cosmology and current knowledge of the X-ray cluster properties, concluding that a reduction of concordance sigma_8 value by 5% is required in order to match the prediction of the model and the data. This conclusion still needs verification through the completion of cluster follow-up.

description: Purpose: Physiological symptoms and comfort levels while wearing an N95 respiratory mask has not been examined with dental hygienists. The purpose of this study was to investigate dental hygiene students reported physiological symptoms and comfort perception while wearing an N95 respirator mask during patient care appointments. Methods: After IRB approval (IRB #1987754-2), a 16-item questionnaire was distributed through email to a convenience sample of 65 dental hygiene students. Questions assessed respiratory, dermatologic, cardiac, mask mouth and general physiological symptoms, as well as comfort levels. Additionally, participants were asked to respond to demographic questions and one open ended question inquiring about any additional physiological conditions not listed in the questionnaire. Descriptive statistics and a paired-sample t-test and an ANOVA test were used for data analysis. Results: An overall response rate of 95% was obtained (n=54). Between the two groups, senior students reported more physiological symptoms at a statistically significant rate when compared to junior students in sore throat (P<0.0011), hypoxia (P<0.0476), an increase in plaque retention (P<0.0028), bad breath (P<0.0047), facial bruising (P<0.003), facial indentations (P<0.0102), facial irritation (P<0.0490), physical fatigue (P<0.0061), headache (P<0.0046), myalgia (P<0.0001), anxiety (P<0.0005), trouble focusing (P<0.0214), jaw pain (P<0.0001), dizziness (P<0.0086), and lightheadedness (P<0.0253). In total, higher means and standard deviations were observed in senior dental hygiene students. Most participants (81.48%) experienced some level of discomfort with no significant difference between senior and junior dental hygiene students level of comfort perception (P<0.642). Conclusion: Both junior and senior dental hygiene students reported physiological symptoms and discomfort related to prolonged N95 respirator mask use while providing patient care.

description:
In the Badenweiler-Lenzkirch Zone (BLZ) of the southern Black Forest, lower Paleozoic metasedimentary rocks of the Sengalenkopfschiefer Formation contain intercalations of diamictites which have been linked to the Hirnantian glaciation. This interpretation is based on lithological arguments and rare palynological remains showing Ordovician to Devonian Acritarch and Chitinozoa associations. This interpretation is challenged by new results of U-Pb dating of detrital zircon grains from four samples of diamictites and associated fine-grained schists. The diamictite layer consists of strongly elongated clasts up to 5 cm in diameter, comprising vein quartz, volcanic detritus, pelites, and minor magmatic pebbles. In total 509 detrital zircon grains were dated by LA-ICP-MS at KIT. These reveal similar age spectra for all four samples, characterized by significant age peaks at ~ 380 Ma, ~ 400 Ma, ~ 480-500 Ma, ~ 600-620 Ma, ~ 700-750 Ma and ~ 1.8-2.2 Ga, and ~ 2.6 Ga, and very small peaks at 0.9-1.1 Ga. The pre-Silurian age populations correspond to the spectra of West Gondwana with minor Mesoproterozoic and very minor Grenville zircons (ca. 1.0 Ga). The two younger age populations fit to a subduction model with an active magmatic arc and published ages for the adjacent Randgranite nappe. The youngest zircon grains reveal maximum depositional ages of ca. 360 Ma, which is close to the Devonian-Carboniferous boundary. This discards the former assumption of Hirnantian glaciation. Instead we hypothesize that the diamictites are linked to the Upper Devonian glaciation which affected North America, South America and West Africa.

description: A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation-mapping and stellar-dynamical estimates of black hole masses. The resulting mass estimates are as accurate as reverberation-mapping and stellar-dynamical estimates. The new mass estimates show that there is very little scatter in the M_{bh} - L_{bulge} relationship for high-luminosity galaxies, and that the scatter increases substantially in lower-mass galaxies.

description: Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. It is being discussed in a number of strongly correlated electron systems. A prototype case occurs in the heavy fermion metals, in which antiferromagnetic quantum critical points have been explicitly observed. Here, I address two types of antiferromagnetic quantum critical points. In addition to the standard description based on the fluctuations of the antiferromagnetic order, a local quantum critical point is also considered. It contains inherently quantum modes that are associated with a critical breakdown of the Kondo effect. Across such a quantum critical point, there is a sudden collapse of a large Fermi surface to a small one. I also consider the proximate antiferromagnetic and paramagnetic phases, and these considerations lead to a global phase diagram. Finally, I discuss the pertinent experiments on the antiferromagnetic heavy fermions, briefly address the case of ferromagnetic heavy fermions, and outline some directions for future studies.

description:
The concern with teaching centred on the characteristics and students’ needs is one of the reasons why the Multiple Intelligence (MI) theory is emerging and has become a trend in educational settings at the elementary, secondary, and higher education levels. Especial literature considers that intelligence is no longer restricted to cognitive talents but rather the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. These characteristics are based on eight types of intelligence Musical, Linguistic, Logical-Mathematical, Spatial, Bodily-Kinesthetic, Interpersonal, Intrapersonal and Naturalist intelligence. Exploring students' learning styles through their MI type allows teachers to identify their strengths and weaknesses and explore these styles in teaching methodologies. Additionally, teachers must understand students’ learning styles and MI to define activities that fit the different bits of intelligence by promoting better educational environment processes. In a pedagogical intervention program implemented in classes of the curricular unit of Didactics of Geology II (that integrates the curriculum of a master to train students to become biology and geology teachers), activities were carried out to teach and consolidate knowledge about Rock Cycle. After the intervention program, students presented the Rock Cycle in accordance with their style of learning. A content analysis was done on twenty-one “snapshot reports” done by the pre-service teachers. As in several studies that refer to the success of using the MI in the teaching process, our study gathered evidence of students' increased motivation to learn and a more active engagement.

description: Inadequate diet is the leading risk factor for morbidity and mortality worldwide. However, approaches to identifying inadequate diets in clinical practice remain inconsistent, and dietary interventions (on both individual and public health policy levels) frequently focus on facilitating ‘healthy choices’, with limited emphasis on structural constraints. We examine the ethical implications of introducing a routine question in the medical history about ability to access food. Not collecting data on food security means that clinicians are unable to identify people who may benefit from support on an individual level, unable to consider relevant dietary risk factors for disease and disease progression and unable to monitor population trends and inequalities in dietary access in order to design effective policy interventions. We argue that the current lack of routine screening for food insecurity is inconsistent with our approach to other health behaviours (eg, smoking and alcohol use), as well as with doctors’ frequent informal role as gatekeepers to the food aid system, and recent calls for governmental action on food insecurity and health inequalities from individual clinicians and professional bodies. Potential ethical barriers to asking patients about food security are addressed, including concerns about stigma, limiting autonomy, fair resource allocation, unclear professional remits and clinicians’ ability to offer effective interventions. We suggest that there is an ethical imperative for doctors to ask patients about their ability to access healthy food. Gathering this data provides a valuable first step in re-framing the social determinants of health as modifiable risks, rather than inevitable inequities.
Scn9a Na⁺ channels in beta-cell survival and type 1 diabetes
Creators: name: Overby, Peter
Publisher: name: University of British Columbia

description: Pancreatic β-cells β-cells are critical for systemic glucose homeostasis, and most of them undergo cell death during the pathogenesis of type 1 diabetes. We previously showed that a Na⁺ channel inhibitor, carbamazepine, could protect β-cells in vitro and in vivo. To define the molecular mechanism of carbamazepine actions in the context of type 1 diabetes, we developed new mouse strains including non-obese diabetic (NOD):Ins1ᶜʳᵉ mice. Comparison of wildtype (Ins1ʷᵗᐟʷᵗ), Ins1 heterozygous (Ins1ᶜʳᵉᐟʷᵗ or Ins1ᴺᵉᵒᐟʷᵗ), and Ins1 null (Ins1ᶜʳᵉ/ᴺᵉᵒ) littermates on a NOD background, showed that female Ins1ᴺᵉᵒᐟʷᵗ mice exhibited significant protection from diabetes, with further near-complete protection in Ins1ᶜʳᵉᐟʷᵗ mice. To investigate the specific role of the Na⁺ channel gene, Scn9a, in β-cell function and survival, we generated a β-cell specific knockout of Scn9a on the NOD background by crossing the floxed Scn9a allele onto the Ins1ᶜʳᵉ knock-in mouse line, resulting in following genotypes: knockout (NOD.Ins1ᶜʳᵉ;Scn9aᶠˡᵒˣᐟᶠˡᵒˣ), heterozygous (NOD.Ins1ᶜʳᵉ;Scn9aᶠˡᵒˣᐟʷᵗ), and wildtype littermate controls (NOD.Ins1ᶜʳᵉ;Scn9aʷᵗᐟʷᵗ). Indeed, we observed near complete ablation of Na⁺ currents in knockout β-cells, and intermediate Na⁺ currents in the heterozygotes. Glucose-stimulated insulin release was significantly reduced from NOD.Ins1Cre;Scn9aʷᵗᐟᶠˡᵒˣ and NOD.Ins1ᶜʳᵉ;Scn9aᶠˡᵒˣᐟᶠˡᵒˣ islets from both male and female mice. Carbamazepine also inhibited glucose-stimulated insulin secretion, from both mouse and human islets, and the effects of carbamazepine on insulin secretion in vitro were not additive to the effects of Scn9a knockout, suggesting that Scn9a is the target of carbamazepine in β-cells. Complete Scn9a deletion also protected β-cells from death in vitro, and non-additively to carbamazepine treatment. Because we could not assess type 1 diabetes incidence in NOD.Ins1ᶜʳᵉ;Scn9aᶠˡᵒˣᐟᶠˡᵒˣ without being confounded by the protective effect of the Cre recombinase knock-in and replacement of one Ins1 allele, we studied NOD.Scn9aᶠˡᵒˣᐟᶠˡᵒˣ after AAV8-Ins1ᶜʳᵉ virus delivery and their virus-injected NOD.Scn9aʷᵗᐟʷᵗ littermate controls. A significant protective effect of Scn9a deletion on diabetes incidence was measured. Our data show Scn9a plays important roles in β-cell function, but also contributes to β-cell death in the context of diabetes-relevant stresses and type 1 diabetes progression. Scn9a may therefore be a novel drug target to preserve β-cells in type 1 diabetes.

description:
Promoting quality education implies that teachers are reflective professionals, agents of innovation and change leaders, able to train students with critical thinking skills, problem-solving, creativity, collaborative work, and communication. In this conscious reflection, it becomes fundamental to shift the focus from teaching to learning, including the teacher himself, leading to developing new skills and attitudes, given the imperative of change. Thus, it is essential to establish teachers' continuous training relevant to initial training, which enhances their professional performance and, consequently, educational improvement. However, the pedagogical practices implemented in training must reflect congruent teaching with what is recommended as desirable in the professional version of future teachers, making the articulation between theory and practice a practical reality. In this action-research process, a pedagogical intervention programme was implemented in the course unit Didactics of Geology II of the master’s degree in biology and geology, according to an inquiry-based methodology focused on the active participation of the students and collaborative work among peers. With a holistic view of the Earth system for understanding the geological phenomena and processes, practical work was done. The laboratory and experimental geosciences activities were adapted from Orion’ previous work and contextualised according to the Portuguese Curriculum of the K7 grade. It was possible to collect evidence showing that pre-service teachers were encouraged to change their visions about how (geo)science can be learned and taught. Results reveal that the practical activities promoted (geo)science reasoning, meaningful learning, and professional development.

description:
limatic optima and hyperthermals of the Paleogene period (66-34 Ma) open windows into the past to explore the Earth System under extreme conditions, beyond several tipping points. During this period Central Asia was intensely hot and arid and offered only a few corridors between Asian and European ecosystems that enabled significant dispersal events such as the "Grande Coupure". These events may have beentriggered by climatic and/or paleogeographical events including the fluctuations of the proto-Paratethysepicontinental sea and its progressive retreat. To date, it has been difficult to disentangle these various forcing factors.Sedimentary sections and associated climate tracers in this region and period are notoriously rare, and existing records suffer from poor age control that precludes robust correlations. We present here a high-resolution magnetostratigraphic dating of integrated environmental proxies from deposits of the Ili Basin, Kazakhstan, bearing rare Eocene mammal fossils. Preliminary results suggest the section encompasses a significantly wetter phase that can be precisely correlated to the Middle Eocene Climate Optimum, a globally recognized hyperthermal expressed by various extreme climate events from 40.5 to 40.1 Ma. In the studied Ili Basin record, Mammal fossils are reported to come precisely from this wet interval. This singular concentration of evidence suggests the MECO may have promoted Eurasian dispersal, however, further climate modelling and proxy data are required to identify potential controlling mechanisms.

description: In this paper we determine the velocity, the energy and estimate writhe and twist helicity contributions of vortex filaments in the shape of torus knots and unknots (toroidal and poloidal coils) in a perfect fluid. Calculations are performed by numerical integration of the Biot-Savart law. Vortex complexity is parametrized by the winding number $w$, given by the ratio of the number of meridian wraps to that of the longitudinal wraps. We find that for $w<1$ vortex knots and toroidal coils move faster and carry more energy than a reference vortex ring of same size and circulation, whereas for $w>1$ knots and poloidal coils have approximately same speed and energy of the reference vortex ring. Helicity is dominated by the writhe contribution. Finally, we confirm the stabilizing effect of the Biot-Savart law for all knots and unknots tested, that are found to be structurally stable over a distance of several diameters. Our results also apply to quantized vortices in superfluid $^4$He.

description: Objectives: Until this point there was no national core competency framework for clinical informatics in the UK. We report on the final two iterations of work carried out in the formation of a national core competency framework. This follows an initial systematic literature review of existing skills and competencies and a job listing analysis. Methods An iterative approach was applied to framework development. Using a mixed-methods design we carried out semi-structured interviews with participants involved in informatics (n=15). The framework was updated based on the interview findings and was subsequently distributed as part of a bespoke online digital survey for wider participation (n=87). The final version of the framework is based on the findings of the survey. Results: Over 102 people reviewed the framework as part of the interview or survey process. This led to a final core competency framework containing 6 primary domains with 36 subdomains containing 111 individual competencies. Conclusions: An iterative mixed-methods approach for competency development involving the target community was appropriate for development of the competency framework. There is some contention around the depth of technical competencies required. Care is also needed to avoid professional burnout, as clinicians and healthcare practitioners already have clinical competencies to maintain. Therefore, how the framework is applied in practice and how practitioners meet the competencies requires careful consideration.

description:
The Atacama Desert is the oldest and driest non-polar desert on Earth, where salts have accumulated through atmospheric deposition over millions of years of hyperaridity. These salts can serve as an indicator to provide an understanding of the interaction between water and soil in changing environmental conditions. Therefore, four soil profiles were studied for their mineralogy, abundance of salts, and stable isotopic composition of sulfate. In all soil profiles, sulfates are the predominant salts showing a downward transition from gypsum to anhydrite accompanied by an increase in highly soluble salts and a decrease in δ34S and δ18O values of sulfate. These trends are consistent with downward water infiltration during rare rain events causing salt dissolution and subsequent precipitation in the deeper soil column. This conclusion is also supported by our Rayleigh fractionation model. The presence of anhydrite at >40 cm depth is attributed to their association with nitrate and chloride salts, which reduces water activity during sulfate precipitation and thus stimulates anhydrite formation. Along the elevation transect, the total salt inventories of the individual profiles show a tendency for nitrate and chloride concentrations to decrease with elevation. This observation, together with the stable isotopes of sulfate, suggests a fog-independent source and points to the remobilization of soluble salts by enhanced erosion of the hillslopes. These findings are essential for understanding pedogenetic processes and long-term regional habitability of hyperarid environments.

description: The thermal drift of the characteristic wavelength of fiber Bragg gratings (FBGs) photowritten in the core of microstructured fibers (MOFs) is significantly reduced by inserting a liquid of suitable refractive index into their holes. For instance, the spectral range of variations is divided by a factor of 4 over a temperature range larger than 20\degree C in a six-hole MOF, and the maximum sensitivity is reduced. Such passive FBG temperature compensation technique is of great interest for applications involving accurate sensing free of thermal effects.

Die Südharz Kali GmbH, eine 100%ige Tochtergesellschaft der South Harz Potash Ltd., eine in Australien gelistete Aktiengesellschaft, hat 2017 das Bergwerkseigentum (BWE) Ohmgebirge erworben und beabsichtigt dort die Gewinnung von Kalisalzen. Das BWE Ohmgebirge grenzt im SW bzw. W an die Grubenfelder der ehemaligen Kalibergwerke Bischofferode und Sollstedt. Dort wurden bereits Ende des 19./Anfang des 20. Jahrhunderts, zwischen 1956 und 1965 und in den 1980er Jahren in mehreren staatlich finanzierten Erkundungskampagnen wirtschaftlich interessante Kalisalzvorräte nachgewiesen. In den Jahren 2017 und 2019 erfolgte zunächst die Neubewertung dieser historischen Erkundungsdaten. 2022 wurden zwei neue Tiefbohrungen abgeteuft, durch die die Resultate unmittelbar benachbarter historischer Bohrungen aus den Jahren 1906 und 1983 bestätigt wurden.
 Im Posterbeitrag werden die Erkundungsstrategie und die Resultate der jüngsten Bohrerkundung im Südharz-Kalirevier vorgestellt.

Nachdem die Kalidüngemittelproduktion in den 1860er Jahren in Staßfurt, im nördlichen Harzvorland, ihre weltweite Premiere erlebte, sich zunächst auf das sogenannte Nordharz-Kalirevier beschränkte, begann auf Betreiben des preußischen Bergbeamten Pinno - und entgegen der damaligen akademischen Lehrmeinung Ochsenius’ - schon in den 1880er Jahren die Erkundung der südlich des Harzes gelegenen Kalivorkommen. Die erste Bohrung Hochstedt wurde westlich Nordhausen bei Günzerode platziert und im November 1888 eingestellt ohne Kalisalze erreicht zu haben. Die zweite Bohrung bei Kehmstedt traf im Juli 1889 ein 63m mächtiges Kalisalzlager an. Bis November 1897 folgten weitere 64 Erkundungsbohrungen in über 50 Gemarkungen bis das erste - vom Preußischen Staat finanzierte - Bohrprogramm im November 1897 mit dem Nachweis der großflächigen Verbreitung bauwürdiger Hartsalz- und Carnallitit-Vorräte erfolgreich abgeschlossen wurde.

Bereits kurze Zeit nach der ersten fündigen Kalibohrung im preußischen Hoheitsgebiet des Südharz-Revieres startete auch die erste privatrechtliche Kapitalgesellschaft die Bohrerkundung auf Kalisalze im August 1891 bei Jecha, Fürstentum Schwarzburg-Sondershausen. Die Bohrung erreichte in 626,20m Teufe ein über 12m mächtiges Carnallitit-Lager, was für den Markscheider, Bergbauunternehmer und Brauereibesitzer Brügmann aus Dortmund als hinreichender Bauwürdigkeitsnachweis genügte, so dass bereits im Mai 1893 mit dem Teufen des ersten Kalischachtes im Südharz-Revier begonnen wurde. Die bergmännische Gewinnung der Kalisalze begann ab 1896 auf dem nach ihm benannten Brügmann-Schacht der Gewerkschaft "Glückauf" in Sondershausen, worauf rasch weitere Bergwerke folgten. Bereits 1914 verfügte das Südharz-Revier über 33 Schächte, zum Jahreswechsel 1924/25 waren es bereits 50 vollendete Schachtanlagen mehrerer Kaligesellschaften, die in der Folgezeit verschiedene, auch staatlich gelenkte Konsolidationen und Stilllegungen erfuhren.

description: We present the latest results for the equation of state and the crossover transition in 2+1 flavor QCD from the HotQCD Collaboration. Bulk thermodynamic quantities - energy density, pressure, entropy density, and the speed of sound - are calculated on lattices with temporal extent $N_t = 8$ in the temperature range 140 < T < 540 MeV. We utilize two improved staggered fermion actions, asqtad and p4, with the mass for the two degenerate light quarks chosen to be $m_{ud} = 0.1 m_s$, corresponding to $m_π\approx 220$ MeV for the lightest pion. We also calculate observables that are sensitive to the chiral and deconfing transitions - the light and strange quark number susceptibilities, the chiral condensate, and the renormalized Polyakov loop - finding that deconfinement and chiral symmetry restoration occur in the same narrow temperature interval.

description: Excerpt from the report Introduction: Many farmers have increased their returns from soybeans by obtaining better yields and reducing cost of production, but relatively few have done so by obtaining better prices. Better prices--and more profitable returns--usually can be obtained by many farmers, however, by taking advantage of seasonal price variation. Soybean growers can avoid selling at depressed harvest-time prices simply by storing the soybeans for later sale. They can provide storage on their farms or they can store at commercial warehouses, if space is available. And while increasing their soybean profits through storage, they will be helping to reduce other serious marketing problems.

description: Social influence drives both offline and online human behaviour. It pervades cultural markets, and manifests itself in the adoption of scientific and technical innovations as well as the spread of social practices. Prior empirical work on the diffusion of innovations in spatial regions or social networks has largely focused on the spread of one particular technology among a subset of all potential adopters. It has also been difficult to determine whether the observed collective behaviour is driven by natural influence processes, or whether it follows external signals such as media or marketing campaigns. Here, we choose an online context that allows us to study social influence processes by tracking the popularity of a complete set of applications installed by the user population of a social networking site, thus capturing the behaviour of all individuals who can influence each other in this context. By extending standard fluctuation scaling methods, we analyse the collective behaviour induced by 100 million application installations, and show that two distinct regimes of behaviour emerge in the system. Once applications cross a particular threshold of popularity, social influence processes induce highly correlated adoption behaviour among the users, which propels some of the applications to extraordinary levels of popularity. Below this threshold, the collective effect of social influence appears to vanish almost entirely in a manner that has not been observed in the offline world. Our results demonstrate that even when external signals are absent, social influence can spontaneously assume an on-off nature in a digital environment. It remains to be seen whether a similar outcome could be observed in the offline world if equivalent experimental conditions could be replicated.
