    Description: The ability to use data produced by different sources (social networks, governments, weather sensors etc.) is widely recognized as a key to capitalize the value of data. In the scientific field, such usage may incredibly boost the innovation and foster new discoveries. However, one of the main hurdles is currently represented by the difficulties in achieving the required interoperability to provide integrated access to multi-disciplinary data. The current work presents a metadata-driven approach that uses in a combined way metadata, semantics, and services as key components for providing integrated access to heterogeneous data sources. The integration occurs within a central data integration system, which is driven by a rich metadata catalogue and that can present the data provided by the different data sources in a harmonised way to the end user, by means of RESTful APIs. A real application demonstrating metadata-driven semantic and service interoperability for achieving homogeneous access to multi-disciplinary heterogeneous data sources is illustrated in the case of EPOS, a Research Infrastructure for Solid Earth Science. The advantages in terms of ease of maintenance, of flexibility in plugging different standard without perturbating communities’ long-lasting technical practices, and of ability to track provenance are discussed. Future work for providing open-source implementation of a system built following the proposed approach is also envisaged.

    Description: The Shapes Constraint Language (SHACL) has been recently introduced as a W3C recommendation to define constraints for validating RDF graphs. In this paper a novel SHACL-driven multi-view editor is presented: SHAPEness. It empowers users by offering them a rich interface for assessing and improving the quality of metadata represented as RDF graphs. SHAPEness has been developed and tested in the framework of the European Plate Observing System (EPOS). In this context, the SHAPEness features have proven to be a valuable solution to easily create and maintain valid graphs according to the EPOS data model. The SHACL-driven approach underpinning SHAPEness, makes this tool suitable for a broad range of domains, or use cases, which structure their knowledge by means of SHACL constraints.

    Description: When a lava flow enters a body of water, either a lake, sea, river or ocean, explosive interaction may arise. However, when it is an 'a'ā lava flow entering water, a more complex interaction occurs, that is very poorly described and documented in literature. In this paper, we analysed the 2–4 ka San Bartolo lava flow field emplaced on the north flank of Stromboli volcano, Italy. The lava flow field extends from ~ 650 m a.s.l. where the eruptive fissure is located, with two lava channels being apparent on the steep down to the coast. Along the coast the lava flow field expands to form a lava delta ~ 1 km wide characterised by 16 lava ‘Flow’ units. We performed a field survey to characterise the features of lava entering the sea and the associated formation of different components and magnetic measurements to infer the flow fabrics and emplacement process of the lava flow system. We measured the density, porosity and connectivity of several specimens to analyse the effect of lava-water interaction on the content in vesicles and their connectivity and conducted a macroscopic componentry analysis (clast count) at selected sites to infer the character of the eroded offshore segment of the lava flow field and its component flow units. The collected data allowed us to define the main components of a lava delta fed by 'a'ā lava flows, with its channels, littoral units, ramps, lava tubes, and inflated pāhoehoe flows controlled by the arterial 'a'ā flow fronts. The spatial organisation of these components allowed us to build a three-step descriptive model for 'a'ā entering a water. The initial stage corresponds to the entry of channel-fed 'a'ā lava flow into the sea which fragments to form metric blocks of 'a'ā lava. Continued lava supply to the foreshore causes flow units to stall while spreading over this substrate. Subsequent 'a'ā lava flow units ramp up behind the stalled flow front barrier. Lava tubes extending through the stalled flow barrier feed the seaward extension of a bench made of several pāhoehoe flow units.

    Description: Groundwater is a vital resource for humans, non-human species, and ecosystems. It has allowed the development of human evolution and civilizations throughout history (e.g., Wittfogel 1956, Tempelhoff et al. 2009, Cuthbert and Ashley 2014, Roberts 2014). However, it faces multiple potential threats that make it vulnerable and fragile. Climate change and human activities are the primary causes that have led to water cycle disruptions, particularly a decline in groundwater quality and quantity (e.g., Gleeson et al. 2020, Chaminé et al. 2022, Richardson et al. 2023). Climate variability has induced droughts, floods, and other extreme weather conditions, significantly impacting groundwater in many regions. Meanwhile, human activities such as over-abstraction, ground contamination, deforestation, land-use change, and other anthropogenic pressures have further compromised groundwater status. Nonetheless, groundwater continues to fulfill water demands in many regions or during specific periods. Therefore, concerted efforts are imperative to ensure its sustainability. So, conservation practices and nature-based solutions must be adopted to efficiently manage groundwater and shield it from additional potential hazards or risks (e.g., contamination, pollution, or over-abstraction). Failure to act quickly can result in the loss of this critical resource, with severe consequences for the economy, society, and ecosystems. From this perspective, it is imperative to prioritize actions underscored by technical-scientific integrity, environmental responsibility, societal sensitivity, and ethical practices.

    Description: Calving of iceberg at ice shelves and floating glacier tongues is a poorly understood process, hence a physically motivated calving law is not yet existing. The demands on developing appropriate models for calving is large, as calving rates are needed for large scale ice sheet models that simulate the evolution of ice sheets. Here, we present a new approach for simulating fracture in ice. Our model is based on a finite strain theory for a viscoelastic Maxwell material, as the large simulation time leads to high strains. The fracturing process is simulated using a fracture phase field model that takes into account the elastic strain energy. We conduct simulations for a typical calving front geometry, with ice rises governing the formation of cracks. To represent the stress state adequately, we first conduct a spin-up to allow the viscous contribution to develop before the fracture phase field is computed. The analysis comprises the assessment of the crack path in comparison to observations, the influence of the spin-up, as well as elastic versus viscous strain contributions based on Hencky strain. Additionally, an estimate of released energy based on high resolution optical imagery of a Greenlandic calving front is presented.

    Description: We have provided the first estimate of scat- tering and intrinsic attenuation for the Gargano Prom- ontory (Southern Italy) analyzing 190 local earthquakes with M L ranging from 1.0 to 2.8. To separate the intrin- sic Q i and scattering Q s quality factors with the Wen- nerberg approach (1993), we have measured the direct S waves and coda quality factors ( Q 𝛽 , Q c ) in the same volume of crust. Q 𝛽 parameter is derived with the coda normalization method (Aki 1980) and Q c factor is derived with the coda envelope decay method (Sato 1977). We selected the coda envelope by performing an automatic picking procedure from T start = 1.5T S up to 30 s after origin time (lapse time T L ). All the obtained quality factors clearly increase with frequency. The Q c values correspond to those recently obtained for the area. The estimated Q i are comparable to the Q c at all frequencies and range between 100 and 1000. The Q s parameter shows higher values than Q i , except for 8 Hz, where the two estimates are closer. This implies a pre- dominance of intrinsic attenuation over the scattering attenuation. Furthermore, the similarity between Q i and Q c allows us to interpret the high Q c anomaly previ- ously found in the northern Gargano Promontory up to a depth of 24 km, as a volume of crust characterized by very low seismic dumping produced by conversion of seismic energy into heat. Moreover, most of the earth- quake foci fall in high Q i areas, indicating lower level of anelastic dumping and a brittle behavior of rocks.

    Description: This review summarizes what the volcanology community has learned thus far from studying the deposits of pyroclastic currents (PCs) from the 1980 eruption sequence at Mount St. Helens. The review includes mass flow events during the May 18 eruption, including the lateral blast, the afternoon column collapse and boil-over PC activity, and some aspects of the debris avalanche. We also include a summary of PCs generated in the smaller eruptions following the climactic May 18 event. Our objective is to summarize the state of our understanding of PC transport and emplacement mechanisms from the combination of field and laboratory observations, granular flow experiments, and numerical modeling techniques. Specifically, we couple deposit characteristics, experiments, and numerical modeling techniques to critically address the problems of (1) constraining conditions in the flow boundary zone at the time of deposition; (2) the influence of substrate roughness and topography on PC behavior; (3) the prevalence, causes, and consequences of substrate erosion by PCs; and (4) the reconstruction of PC transportation and sedimentation processes from a combination of geophysical and sedimentological observations. We conclude by providing opportunities for future research as our field, experimental, and numerical research techniques advance.

    Description: The ability to predict the mobility of rock avalanches is necessary when designing strategies to mitigate the risks they pose. A popular mobility indicator of the flow front is the Heim’s apparent friction coefficient muH. In the field, muH shows a decrease in value as flow volume V increases. But this correlation has been a mystery as to whether it is due to a causal relationship between V and mobility since: (1) field data of muH do not collapse onto a single curve because typically widely scattered and (2) laboratory experiments have shown an opposite volume effect on the center of mass mobility of miniature flows. My numerical simulations confirm for the first time the existence of a functional relationship of scaling parameters where muH decreases as V increases in unsteady and nonuniform 3D flows. Data scatter is caused by muH that is affected by numerous other variables besides V. The interplay of these variables produces different granular regimes with opposite volume effects. In particular, muH decreases as V increases in the regime characterized by a relatively rough subsurface. The relationship holds for large-scale flows that, like rock avalanches, consist of a very large number of fine clasts traveling in wide channels. In these dense flows, flow front mobility increases as flow volume increases, as channel width increases, as grain size decreases, as basal friction decreases and as flow scale increases. Larger-scale flows are more mobile because they have larger Froude number values.

    Description: Invasive alien species represent one of the main environmental threats to native biodiversity and can also strongly alter the biogeochemical cycles within an ecosystem. This study aims to define the distribution of the invasive alien species Cotula cor-onopifolia L. within the protected wetland "Variconi" (Campania region, southern Italy) and evaluate the potential role of water geochemical features as interpretation tools for pattern distribution. The presence of C. coronopifolia was assessed in the field, and a distribution map was drawn; concomitantly thirty-nine water samples were collected from groundwater and surface water bodies for chemical analyses. The results showed that C. coronopifolia preferentially colonized the sector of the wetland characterized by high halinity, while it is totally absent in retrodunal and sandy coastal area with very high halinity. The cartography presented can be used as a tool to help target future management interventions. Through our multidisciplinary approach, new evidence has been provided on the ecology of this invasive alien plant that occupies several wetlands worldwide. The replicability of this method may be useful to assess the level of invasion of an alien species but also to predict its evolution as a function of environmental parameters.

    Description: Active volcanoes show many mild thermal anomalies, because the ground surface is sensible to changes in the advective processes, occurring through the network of fissures. This data report shows the temperatures, recorded from January 2020 to February 2023, by a remote-controlled monitoring station. The VCS station is located on the summit of La Fossa cone (Vulcano, Aeolian Islands), in a zone of intense diffuse degassing. The temperature data, hourly registered at VCS, are available in the supplementary Excel file. The thermal data are part of the comprehensive network, performed by the Istituto Nazionale di Geofisica e Vulcanologia, for volcanic surveillance. On the Island of Vulcano, the active volcanic system under la Fossa caldera has been affected by multiple exhaling crises, interpreted as unrest of volcanic activity. The temperature time series provided reference data showing the thermal transition of the volcanic ground surface from a background degassing condition, through unrest, to the new thermal condition that followed the unrest period.

    Description: Earth System Literacy offers a rich matrix of narratives about (planet) Earth, World and Humans when interwoven with cultural artefacts (e.g. arts, history). Anthropogenic global change locks them together in a unifying framework. By making a distinction between reproduction, work (ergon, Greek) and civicness, there are narratives that convey what characterises the human condition today, including the material, social and historic settings of the Anthropocene.

    Notes: Zusammenfassung Legende Hennen erhielten ein Futter, dem 180 Tage lang 2 mVal Strontium- und 218 Tage lang dieselbe Menge Calciumcarbonat beigemischt war. Sie legten im Verlauf des Versuches mehr als 200 Eier, deren Schalen nach Veraschung auf Strontium und Calcium untersucht wurden. Strontium war bereits am Tage der ersten oralen Aufnahme nachweisbar. Die Strontiumkonzentration zeigte im weiteren Verlauf starke Schwankungen. Sie stieg in höchstens 57 Tagen auf einen Sättigungswert von etwa 2,6% der Asche an, Nach Beendigung der Strontiumverabreichung war Strontium in der Schalenasche noch mehr als 200 Tage lang nachweisbar. Der Befund wird als Umlagerung von Skelett-Strontium in die Schale erklärt.

    Description / Table of Contents: Résumé Nous avons étudié chez le rat diverses cardiopathies expérimentales à caractères histologiques différents. Ces études comparatives avaient pour objet d'évaluer le rôle de certains anions et cations (notament, le K, Mg, Na et le Cl) dans la pathogénèse des cardiopathies métaboliques provoquées par des agents chimiques mais en l'absence de toutes modifications histologiquement démontrables des artères coronaries. Il fut observé que des variations du contenu en cations K et Mg ou encore en anions Cl et PO4 dans la diète, jouent un rôle important dans la pathogénèse de certaines cardiopathies nécrosantes tout autant que dans le mécanisme fondamental des réactions adaptives qui modifient la susceptibilité du myocarde. Nous avons constanté en outre que la plupart des agents capaples d'induire des lésions cardiaques par un mécanisme biochimique ont un potentiel pathogène et que leurs effets cardiotoxiques dépendent d'autres facteurs ou conditions. Ainsi, les hormones corticoïdes, les sels de Na, les déficiences alimentaires en K, Mg et Cl, les stress aigus, l'âge et la sclérose des artères coronaires tiennent lieu d'agents sensibilisateurs alors qu'un excès en Cl, une déficience en Na, une adaptation aux agents stressants et la gestation désensibilisent le myocarde à la production de lésions cardiaques (nécrose, inflammation, calcification) par des agents à potentiels pathogènes les plus divers. Par ailleurs, les infarctus cardiaques provoqués par l'occlusion chirurgicale des artères coronaires chez le rat, montrent des différences fondamentales avec les cardiopathies métaboliques que nous avons étudiées. Ces derniers, en effet, out pour caractéristique de dépendre essentiellement d'une interaction entre les anions et les cations et n'ont pas un seul agent pathogène. L'importance du K, Mg, Na et du Cl dans la pathogénèse des nécroses du myocard et le rôle possible de l'équilibre ionique dans la production et la prévention des maladies cardiaques de type nécrosant sont discutés sur la base des études expérimentales effectuée par l'auteur et de diverses observations décrites par l'auteur.
    Notes: Summary Experimental cardiopathies that are widely different in their histologic characteristics were studied in the albino rat. The main purpose of these comparative investigations was to determine the participation of various cations and anions (especially of K, Mg, Na and Cl) in the pathogenesis of metabolic cardiopathies that are induced by chemical means, but are not accompanied by histologically detectable changes of the coronary arteries. It was observed that variations in dietary intake, not only of certain cations (K and Mg) but also of the anions (Cl and PO4), play an important role in the pathogenesis of certain necrotizing cardiopathies as well as in the mechanism of adaptive reactions that basically alter the disease-susceptibility of the myocardium. It was also noted that most of the agents that are capable of inducing cardiac lesions through some biochemical mechanism are potentially acting pathogens, whose cardiotoxicity largely depends upon other factors or conditions: some of which (i. e., corticoids, Na-salts, dietary deficiencies in K, Mg and Cl, sudden stress situations, age and coronary sclerosis) uniformly sensitize, while others (i. e., Cl-excess, Na-deficiency, adaptation to stressor agents and the condition produced by pregnancy) desensitize the myocardium to the production of cardiac lesions (necrosis, inflammation, calcification) by most diverse potentially pathogenic agents. On the other hand, the cardiac infarcts that can be produced by surgical occlusion of coronary arteries in the rat, differ basically in many respects from all metabolic cardiopathies studied. The latter are characterized precisely by the fact that they depend upon complex anion-cation interactions, not upon a single pathogen. The importance of K, Mg, Na and Cl in the pathogenesis of cardiac necroses and the possible role of the ionic equilibrium in the production and prevention of necrotizing cardiac diseases are discussed on the basis of experimental studies performed by the author and of previous observations described by others.

    Description / Table of Contents: Zusammenfassung Die Blasengalle von Hamstern wurde aufph, Cholesterin, Lipid-Phosphor, Glycinkonjugierte Cholsäure, Chenodesoxycholsäure und Desoxycholsäure, sowie Taurin-konjugierte Cholsäure und Chenodesoxy- plus Desoxycholsäure analysiert. Ein Teil der Tiere wurde von einem Alter von 30 bis 46 Tagen an während Zeiträumen verschiedener Länge mit den unten angeführten Nahrungen gefüttert: 1. Eine fettfreie Nahrung mit Glucose als Kohlenhydrat-Komponente, die an jungen Hamstern Cholesterin-Gallensteine hervorruft. 2. Eine fettfreie Nahrung mit Reisstärke als Kohlenhydrat-Komponente, welche die Bildung von Cholesterin-Gallensteinen fast aufhebt. 3. Eine fettfreie Nahrung mit Lactose als Kohlenhydrat-Komponente, welche ebenfalls die Bildung von Cholesterin-Gallensteinen stark herabsetzt. 4. Eine Nahrung komplizierterer Zusammensetzung, enthaltend u. a. 10% Schweineschmalz, 20% Casein, 36% Trockenhefe, 28,3% gemahlenen, polierten Reis und ein Salzgemisch mit Zusatz von Cu („Kurative Nahrung“), welche die Bildung von Cholesterin- und amorphen pigmentierten Gallensteinen vollkommen aufhebt, und schon gebildete Cholesterin-Gallensteine in Lösung bringen kann. Ein anderer Teil der Tiere wurde im Alter von 107–111 Tagen von der „Stock diet“ bzw. von der „Stock diet“ mit einer mäßigen Zulage von Salat und Möhren zu der fettfreien Nahrung 1. überführt. Die Ergebnisse waren: Dasph war hauptsächlich dasselbe in allen Gruppen. Das reichliche Vorkommen von Cholesterin-Gallensteinen in den Gruppen, welche vom Alter von 30 bis 46 Tagen an mit der fettfreien Glucosenahrung gefüttert wurden, entsprach im allgemeinen einem höheren Cholesteringehalt und niedrigeren Gehältern an Gesamtgallensäuren und deswegen einem niedrigeren Verhältnis von Gesamtgallensäuren zu Cholesterin als in den Gruppen, welche die Reisstärke, bzw. die „kurative“ Nahrung erhielten. In den erwähnten Glucosegruppen und in den Reisstärke-Gruppen war der Gehalt an Lipidphosphor ungefähr gleich und niedriger als in der Gruppe, welche mit der „kurativen“ Nahrung gefüttert wurde. Jedoch trat nach ungefähr 100 Tagen ein Ansteigen der Lipid-Phosphor-Werte in der Reisstärke-Gruppe ein. In den Lactosegruppen lagen die Werte für Cholesterin, Gesamtgallensäuren und Lipidphosphor in der Nähe der entsprechenden Werte der Glucosegruppen, was darauf hindeutet, daß das verhältnismäßig seltene Vorkommen von Cholesterin-Gallensteinen bei Lactose-gefütterten Hamstern teilweise durch andere Faktoren bedingt sein kann. Die Hamster, welche erst im Alter von 107–111 Tagen zu der Glucosenahrung über-führt wurden, bekamen keine Cholesterin-Gallensteine, hatten aber eine ausgesprochene Neigung zur Bildung von amorphen, pigmentierten Gallensteinen (unabhängig davon, ob vorher eine mäßige Zulage von Salat und Möhren gegeben wurde.) Diesem Zustand entsprachen eine Neigung zu höheren Werten des Verhältnisses Gesamtgallensäuren zu Cholesterin, und, besonders eine Neigung zu höheren Werten des Verhältnisses, Lipidphosphor zu Cholesterin verglichen mit den Gruppen, welche im Alter von 30 bis 46 Tagen zu der Glucosenahrung überführt wurden.
    Notes: Summary The composition of bladder bile with respect toph, cholesterol, lipid phosphorus, glycine conjugated cholic, chenodeoxycholic and deoxycholic acids, and of taurine conjugated cholic and chenodeoxycholic plus deoxycholic acids was analyzed in young hamsters reared from the age of 30–46 days for various lengths of time on 1) a fat-free diet with glucose as the carbohydrate component, producing cholesterol gallstones in young hamsters, 2) a fat-free with rice starch as the carbohydrate component which, largely, prevents the formation of cholesterol gallstones. 3) a fat-free diet with lactose as the carbohydrate component which also counteracts the formation of cholesterol gallstones, 4) a diet of more complicated composition, containing 10% of lard, 20% of casein, 36% of dried brewer's yeast, 28.3% of ground polished rice, and with Cu added to the salt mixture. This “curative diet” completely prevents the formation of cholesterol and amorphous pigmented gallstones and causes already formed cholesterol stones to dissolve. The bladder bile of hamsters transferred from the stock colony diet to the glucose diet at the age of 107–111 days was analyzed similarly. Theph was essentially the same in all groups. The abundance of cholesterol gallstones among the hamsters fed the fat-free glucose diet from 30–46 days of age paralleled a tendency to higher levels of cholesterol and lower levels of total bile acids — and, therefore, generally lower levels of the ratio total bile acids/cholesterol than in the groups fed the rice starch diet and the “curative diet”. In the glucose groups and in the rice starch groups the levels of lipid phosphorus were within the same range and lower than in the groups fed the “curative diet”. However, in the rice starch groups the values for lipid phosphorus increased after about 100 days of feeding. In the lactose fed groups, the values for cholesterol, bile acids and lipid phosphorus were almost within the same range as in the glucose groups, suggesting that other factors than those analyzed may be responsible for the rare occurrence of cholesterol gallstones in lactose fed hamsters. The hamsters in the groups transferred to the glucose diet at 107–111 days of age did not get cholesterol stones but had a marked tendency to formation of amorphous pigmented stones. This condition corresponded to a tendency to higher values of the ratios total bile acids/cholesterol, and, especially, lipid phosphorus/cholesterol than in the groups transferred to the glucose diet at the age of 30–46 days.

    Notes: Zusammenfassung Chronische Fütterungsversuche an Ratten mit bestrahltem Sojaöl haben ergeben, daß das öl ab einer Strahlendosis von 10 Mrad toxische Eigenschaften annimmt, die sich in einer hohen Letalität der Tiere äußert. Mit fallender Strahlendosis wird die Latenzzeit bis zum Auftreten der Symptome immer länger. Die Todesursache der Tiere konnt noch nicht geklärt werden. Jedoch konnten an ihnen einige auffallende Symtome festgestellt werden: Ablagerung eines braunen, Eisen enthaltenden Pigments in der Leber und in der Milz, Funktionsstörungen der Leber, Veränderungen der Plasmaproteine, Ihaktivierung der Schilddrüse, Abnahme der Körpertemperatur, Senkung des Grundumsatzes, Bradykardie, Linksverschiebung der Zellkerngröße in der Nebennierenrinde. Die histologische Untersuchung der anderen Organe ergab keine auffallenden Befunde, insbesondere auch nicht des zentralen Nervensystems. Am Verdauungstrakt wurden nur ganz geringfügige Veränderungen gefunden. Die Ausnutzung des bestrahlten öls ist verschlechtert.

    Description / Table of Contents: Zusammenfassung 1. Bei Patienten mit schlechter Absorption wurden modifizierte I131-Triolein- und131I-Oleinsäure-Tests durchgeführt. 2. Eine erhöhte Ausscheidung von131T im Stuhl wurde bei diesen Patienten beobachtet. Insofern hat der Test für diese Gruppe diagnostische Bedeutung. 3. Festal bewirkte einen bemerkenswerten Effekt auf den Absorptions-Test bei dieser Gruppe von Patienten, ebenso bei der Kontrollgruppe von Personen mit ausreichender Verdauung. 4. Symptome, welche zu unzureichender Verdauung führen (insbesondere Meteorismus) konnten durch Festal gebessert werden. 5. Die Stuhlzusammensetzung wurde durch die Anwendung von Festal ebenfalls verbessert. 6. Festal zeigte keine Nebeneffekte.
    Notes: Summary 1. Modified131I-triolein and131I-oleic acid tests were performed on patients of the malabsorption group. 2. Elevated excretion ratio of131I in stool was observed in the malabsorption group. So, this test has a diagnostic value in the malabsorption group. 3. Festal showed a remarkable effect on the absorption test in malabsorption group as well as in a control group having a sufficient digestion. 4. Symptoms due to deficient digestion, especially meteorism, were much improved by Festal. 5. Digestive condition of the stool was also improved by the administration of Festal. 6. Festal had no side effects.

    Notes: Zusammenfassung 1. Anhand eines Wachstumstestes an Wistar-Ratten wird experimentell die Frage erörtert, ob zwischen „Schwerresorbierbarkeit“ und „Thiamin-Spareffekt“ eines Kohlenhydrates ein kausaler Zusammenhang besteht. Hierzu wird den Tieren eine saccharosehaltige Vitamin-B1-Mangeldiät — unter Zusatz ausgewählter Kohlenhydrat-Komponenten (Sorbit, Mannit, Inosit, Sorbose, Fruktose, Dextrin, Stärkesirup, Glukose-Reversionsprodukte, Pektin, Natriumalginat, karamelisierte Saccharose, erhitztes Glukose/Glyzin-Gemisch) — verabfolgt; Coprophagie wird nicht verhindert. 2. Eine Vitamin-B1-sparende Wirkung ist lediglich bei Zugabe von Inosit, Mannit, Sorbit und Pektin zum Mangelfutter sicher erkennbar. 3. Die Befunde weisen aus, daß neben „Schwerresorbierbarkeit“ offenbar noch ein substanzspezifischer Faktor für das Auftreten des Thiamin-Spareffektes verantwortlich zu machen ist. Die Ergebnisse werden diskutiert.

    Description / Table of Contents: Zusammenfassung Koflers pflanzliches Chinon mit Seitenkette von 45 Kohlenstoffatomen, Ubichinon mit Seitenkette von 50 Kohlenstoffatomen, sowie ein synthetisches Analoges vonKoflers Chinon: 2,3-dimethyl-5-phytyl-benzochinon wurden mittels der kurativen Blutgerinnungsmethode in Vitamin K-defizienten Küken auf Vitamin K-Wirkung untersucht. Es wurde gefunden, daß diese Verbindungen als Fehlerquellen bei der Bestimmung von Vitamin K nach dieser Methode keine Rolle spielen können.
    Notes: Summary Kofler's quinone with a side chain of 45 carbon atoms, ubiquinone with a side chain of 50 carbon atoms, and a synthetic analogue of Kofler's quinone, 2,3-dimethyl-5-phytyl-benzoquinone, were assayed for vitamin K activity by the curative blood clotting method in vitamin K deficient chicks. The role of these substances as sources of error in that method was found to be negligible.

    Description / Table of Contents: Zusammenfassung Drei Gruppen von je 10 Küken wurden 4 Wochen lang mit künstlichen, Vitamin E supplementierten Nahrungen gefüttert. In der ersten Gruppe erhielt die Nahrung keine Zulage, in der zweiten Gruppe wurde eine Zulage von 1,5% Äthyllinoleat und in der dritten eine Zulage von 1,5% Äthyllinolenat gegeben. Polyenfettsäuren wurden in Leber, Herz, Hirn und Depotfett mit der Alkali-Isomerisierungs-Methode (8), Cholesterin in Plasma, Leber, Herz, Hirn und Depotfett mittels derLiebermann-Burchard- und Aorta mittels derTschugaeff-Reaktion (7) bestimmt. Die wichtigsten Befunde bezüglich derPolyensäuren waren: In der Linoleat-Gruppe wurde Diensäure in Leber, Herz und Depotfett, Tetraensäure in Leber, Herz und Hirn abgelagert. In der Linolenat-Gruppe wurde Triensäure in Depotfett, Pentaensäure in Leber und Herz, und Hexaensäure in Leber und Hirn abgelagert. Die Gesamtmenge der Polyensäuren in den untersuchten Organen war höher in der Linoleat-Gruppe als in der Linolenat-Gruppe. Die Befunde bezüglichCholesterin waren: Im Vergleich mit der Nahrung ohne Fettsäurezulage führte die Linolenat-Nahrung zu niedrigeren Cholesterin-Werten in Plasma und Leber. Linoleat zeigte keine Wirkung gegenüber dem Plasma-Cholesterin, drückte aber den Cholesteringehalt der Leber mehr herab als Linolenat.
    Notes: Summary Polyenoic fatty acids in liver, heart, brain and depot fat, and cholesterol in plasma, liver, heart, brain, aorta and depot fat were determined in chicks fed a low-fat diet (the fat content of which was only that present inFleischmann yeast 50 B), and the low-fat diet supplemented with 1.5% ethyl linoleate and 1.5% ethyl linolenate, respectively, through 4 weeks. Regardingpolyenoic fatty acids, the most pronounced findings were the following: In the group fed linoleate, dienoic acid was deposited in liver, heart and depot fat, tetraenoic acid was deposited in liver, heart and in brain. In the linolenate group, trienoic acid was deposited in depot fat, pentaenoic acid in liver and heart and hexaenoic in liver and brain. The total amount of polyenoic acids in the organs examined was higher in the linoleate group than in the linolenate group. Thecholesterol contents of heart, brain, aorta and depot fat showed no significant differences between the groups. In plasma and in liver, ethyl linolenate had a depressing effect on the cholesterol content compared with the low-fat diet. Ethyl linoleate had no effect on plasma cholesterol, whereas it depressed liver cholesterol to a greater extent than linolenate.

    Description / Table of Contents: Zusammenfassung Gruppen von 10 Küken wurden mit künstlichen, Vitamin-E-freien Nahrungen, enthaltend 1,5% Äthyl-linoleat, 1,5% Äthyl-arachidonat oder 30% Schweineschmalz, gefüttert. Die Küken waren 5 Tage alt beim Versuchsbeginn. Die Fütterung dauerte bis zu 35 Tagen. Sämtliche Küken in der Arachidonat-Gruppe entwickelten Enzephalomalazie innerhalb von 13 Tagen. In der Linoleat-Gruppe begann die Entwicklung von Enzephalomalazie nach 13 Tagen. Insgesamt 7 der Küken in dieser Gruppe hatten Enzephalomalazie beim Versuchsabschluß. In der Schweineschmalz-Gruppe entwickelte sich die Enzephalomalazie etwas schneller als in der Linoleat-Gruppe, aber langsamer als in der Arachidonat-Gruppe. In früheren Versuchen, in welchen 1,5% Äthyl-linoleat und 1,5% Äthyl-linolenat verglichen wurden, zeigte es sich, daß Linolenat Enzephalomalazie nicht herbeiführte. Es scheint somit, daß der Teil des Linolsäure-Moleküls, welcher die10 letzten Kohlenstoffatome (gerechnet von der Carboxylgruppe) umfaßt, für die Entstehung der Enzephalomalazie von Bedeutung ist. Eine entsprechende Struktur ist in Arachidonsäure vorhanden, nicht aber in Linolensäure. Die höhere Ungesättigtheit der Arachidonsäure könnte zur Überlegenheit dieser Fettsäure als Enzephalomalazie-Erreger beitragen. Es ist auch möglich, daß die Enzephalomalazie-erregende Wirkung der mit der Nahrung zugeführten Linolsäure durch die aus dieser Fettsäure entstandenen Arachidonsäure vermittelt wird. Die Möglichkeit, die Entstehung von Enzephalomalazie auf Grund einerin vivo Autoxydation von Fettsäuren zu erklären, wird diskutiert.
    Notes: Summary Vitamin E-free diets containing 1.5% of the ethyl estera of linoleic and arachidonic acids, respectively, and a vitamin E-free diet containing 30% lard were fed to groups of 10 chicks from the age of 5 days through a period of maximally 35 days. All chicks in the arachidonate group developed encephalomalacia within 13 days. In the linoleate group, encephalomalacia began after 13 days. A total of 7 of the chicks in this group had encephalomalacia at the end of the feeding period. In the group receiving 30% lard, encephalomalacia developed somewhat faster than in the linoleate group but slower than in the arachidonate group. Earlier experiments in which 1.5% of ethyl linoleate and 1.5% of ethyl linolenate were compared showed that ethyl linolenate did not give rise to encephalomalacia within the feeding period. The integrity of that part of the linoleic acid molecule comprising the 10 last carbon atoms (counted from the carboxyl group) seems to be of importance for the development of encephalomalacia. A corresponding structure is present in arachidonic but not in linolenic acid. The additional unsaturation of arachidonic acid may contribute to the superiority of this fatty acid as encephalomalacia producing agent. Further, it is possible that the encephalomalacia producing effect of dietary linoleic acid is mediated by arachidonic acid formed in the tissues from the ingested linoleic acid. The possibility of explaining the development of encephalomalacia on the basis ofin vivo autoxidation of fatty acids is discussed.

    Description / Table of Contents: Zusammenfassung Junge weiße Mäuse entwickelten keine Gallensteine, wenn sie mit einer Nahrung gefüttert wurden, welche in jungen Hamstern Cholesteringallenstein-Bildung hervorruft. Die verwendete Nahrung war fettfrei und hatte Glucose als Kohlenhydrat-Komponente. Die Konzentration von Cholesterin und auch dasph der Blasengalle waren ungefähr gleich in Mäusen und Hamstern. Das Verhältnis Gesamt-Gallensäuren: Cholesterin war etwas höher und das Verhältnis Lipid-Phosphor∶ Cholesterin viel höher bei Mäusen als bei Hamstern. Das Verhältnis Dihydroxycholansäure:Trihydroxycholansäure war viel niedriger bei den Mäusen.
    Notes: Summary Young white mice did not develop gallstones when they were reared on a diet which causes cholesterol gallstones in young hamsters, viz. a fat-free diet with glucose as the carbohydrate component. The cholesterol content andph of the bladder bile of the mice was about the same as previously found for hamsters, but the ratio total bile acids∶cholesterol was somewhat higher and the ratio lipid phosphorus∶cholesterol much higher in the mice than in the hamsters. The ratio dihydroxy∶trihydroxy cholanic acids was much lower in the mice.

    Notes: Zusammenfassung Legenden Hennen wurde 180 Tage lang strontiumhaltiges Futter (Sr:Ca ≈ 1:22) verabreicht; der gesamte Versuch erstreckte sich über 607 Tage. Die Dotter der angefallenen Eier und das Skelett wurden auf Strontium und Calcium untersucht. Das Eigelb enthielt erstmals vier Tage nach Versuchsbeginn einen nachweisbaren Strontiumgehalt, der nach zwei bis drei Wochen ein Niveau um 0,5% der Asche erreichte. Das Strontium:Calcium-Verhältnis des Dotters war jetzt 1:15. Nach Absetzen des Strontiumfutters war Strontium noch bis zum 186. Tag in der Dotterasche nachweisbar. Der Befund wird mit einer Umlagerung von Skelett-Strontium in den Dotter erklärt. In der Asche der Tibiae und Halswirbel stieg der Strontiumgehalt bis zum Ende der Strontiumfütterung auf 0,50 bzw. 0,58% am. Er fiel in den folgenden 427 Tagen auf 0,14 bzw. 0,16% ab.

    Notes: Summary Carcass composition, plasma protein, and hematocrit determinations were carried out on normal adult male chickens, and on adult males depleted by starvation for 4 weeks. For the first 2 weeks of depletion, N excretion was also determined for the starved animals. The following observations were recorded: 1. During 2 weeks of starvation the adult rooster lost approximately 25% of his body weight, and between 10 and 20% of his carcass N. 2. There was no loss in either weight or N content of feathers upon depletion; there was, however, a significant loss in feather fat. 3. The survival time of starved birds appeared to be related to their initial, prestarvation fat reserves. 4. The energy needs for repletion of depleted roosters, expressed on a body weight basis, were considerably higher than those necessary for maintaining normal animals. This appeared to be primarily a reflection of the greater proportion of ‘lean body mass’ (carcass N) in the starved birds.

    Notes: Summary A dietary survey by the interview method was undertaken on the Finnish Lapps in 1960. Data on the food consumption of 135 families including 812 persons in all was collected. The average energy intake varies from 2250 to 2775 kcal in the different Lapp groups, when estimating the waste and refuse at approximately 15% of the total food consumed. The intake of energy may be considered adequate, since the Lapps are of normal physique according to height, weight, and skinfold measurements. The intake of some essential nutrients is scarce, especially that of calcium of the Skolt Lapps, which after deduction of waste is only 370 mg per day. The daily intake of ascorbic acid in the nomadic Mountain Lapp and Skolt groups is as low as 30 mg. Considering the losses of ascorbic acid in food preparation, the intake of this vitamin is very low in both these groups. Of the groups studied, the food of the Skolt Lapps is clearly the poorest.

    Notes: Zusammenfassung Ein überblick über die Verfrachtungsbedingungen von Spaltprodukten bei Kernwaffenversuchen zeigt die sich daraus ergebenden Kontaminationsverhältnisse (Kontaminationsgrad und Fallout-Rate) speziell in der Bundesrepublik Deutschland. Diese beiden Faktoren sind ausschlaggebend für den Kontaminationsgrad landwirtschaftlich genutzter Pflanzen. Ebenso werden Hinweise über die Kontaminationsveränderung bei verschiedenen Nahrungsmittelketten gegeben. Die Ergebnisse der Lebensmittelüberwachung im Hinblick auf eine radioaktive Verseuchung werden zusammengefaßt als „mittlere tägliche Zufuhr“ pro Kopf der Gesamtbevölkerung und verglichen mit einer „maximal zulässigen Zufuhr“ pro Kopf der Bevölkerung, die z. Zt. die beste Möglichkeit zur Abschätzung einer Gefährdung des Menschen durch Aufnahme radioaktiver Substanzen darstellt.

    Description / Table of Contents: Zusammenfassung Eine fettfreie Nahrung mit Glucose als Kohlenhydratkomponente iat besonders geeignet um Cholesterin-Gallenstein-Bildung in jungen Hamstern regelmäßig und in kurzer Zeit zu entwickeln. Die Prüfung von Substanzen auf Schutzwirkung gegen alimentäre Cholesterin-Gallenstein-Bildung ist besonders scharf, wenn die Grundnahrung nach dem oben erwähnten Prinzip zusammengesetzt ist. In einem Versuch von diesem Typ zeigte Hyodesoxycholsäure in einer Menge von 0,1% der Grundnahrung sehr gute Schutzwirkung, während Cholsäure, Desoxycholsäure, Dehydrocholsäure und Lithocholsäure in der Menge von 0,1% der Nahrung keine sichere Schutzwirkung erkennen ließen. In früheren Versuchen, wo die Grundnahrung 2% Schweineschmalz enthielt, und die Kohlenhydratkomponente aus Saccharose bestand, zeigte Desoxycholsäure in einer Menge von 0,1% der Nahrung gute Schutzwirkung, während die mit 0,1% Cholsäure erreichte Schutzwirkung weniger sicher war.
    Notes: Summary A fat-free diet in which the carbohydrate component consists of glucose is particularly suited for rapid and regular production of cholesterol gallstones in young hamsters. Testing of the ablity of substances to counteract dietary formation of cholesterol gallstones can be carried out under the strictest possible conditions known when the composition of the basal diet fallows the above principle. In a test of this type the addition of 0.1 per cent hyodeoxycholic acid to the basal diet afforded a high degree of protection against cholesterol gallstones, whereas a similar protection could not be demonstrated when cholic, deoxycholic, dehydrocholic or lithocholic acids were given at the same dietary level. In earlier experiments with a basal diet containing sucrose instead of glucose and in addition 2 per cent lard, 0,1 per cent deoxycholic acid protected against cholesterol gallstones, whereas it was less certain that cholic acid at the same level was protective.

    Notes: Zusammenfassung Es werden die möglichen Gründe erörtert für die so widerspruchsvollen Angaben über den Einfluß einer fettreichen Kost auf die Gerinnbarkeit des Blutes. Es wird dargelegt, daß diese nur zum Teil in methodischen Unzulänglichkeiten zu sehen sind, vielmehr darüberhinaus vor allem in falschen gedanklichen Voraussetzungen bei der Durchführung und Auswertung der Versuche. Zu diesen gehören 1. die Außerachtlassung des phasischen Charakters der vegetativen Reaktionen, 2. die Annahme, daß es sich um ein bei allen Menschen gleiches Geschehen handele und daß daher die bei einem bestimmten Personenkreis wie gesunden Soldaten oder älteren Patienten erhaltenen Ergebnisse unbedenklich als für alle Menschen gültig anzusehen seien und schließlich 3. die Nichtberücksichtigung der noch innerhalb eines hinsichtlich Alter, Gesundheit, Ernährung einheitlichen Personenkollektives bestehenden erheblichen interindividuellen Reaktionsunterschiede. Unter Berücksichtigung alles dessen wurden eigene Untersuchungen durchgeführt über die Einwirkung einer Fettmahlzeit, welche hauptsächlich aus 200 g mit 75 g Butterschmalz gebratenen Kartoffeln bestand und 932 kcal mit einem Fettanteil von 73,6% enthielt. In dieser 1. Mitteilung wird über die Ergebnisse an 31 gesunden Studierenden im Alter von 21–26 Jahren berichtet, von denen sich 15 fettarm und 16 fettreich zu ernähren pflegten. Im Thrombelastogramm sowie im Thrombinbildungstest zeigten sich große individuelle Reaktionsunterschiede von Verkürzungen über Nichtbeeinflussung bis zu Verlängerungen der Gerinnungszeit; doch waren bei unserem Personenkreis und unter unseren Versuchsbedingungen, zumal im Thrombelastogramm, stärkere Verkürzungen weitaus überwiegend. Sie entwickelten sich bei den Fettungewohnten besonders früh, meist noch vor der Lipämie und hielten auch länger an als bei den Fettgewohnten. Die Verkürzungen der Gerinnungszeit gingen zwar mehrfach bis an die untere Grenze des Normbereiches, unterschritten sie jedoch in keinem Falle. Im Hinblick darauf und insbesondere wegen des Ausbleibens einer stärkeren Steigerung der Thrombuselastizität scheint bei gesunden Jugendlichen selbst eine ganz ungewohnte fettreiche Mahlzeit keine zeitweise Hyperkoagulabilität oder Thrombophilie hervorzurufen vermögen. Auch für die untersuchten fördernden Einzelfaktoren (Ptb, V,VII, VIII, IX und X) fanden sich individuell stark unterschiedliche Reaktionen, wobei es zu stärkeren Steigerungen der Aktivitäten weit seltener kam als in unseren früheren Untersuchungen auf anstrengende körperliche Betätigung. Es fanden sich keine festen Beziehungen zwischen den Ausgangswerten der globalen Gerinnungszeiten sowie deren Veränderungen auf die Fettmahlzeit und den Aktivitäten einzelner dieser fördernden Faktoren oder einer Kombination von ihnen. Solche Beziehungen fehlten auch zu den untersuchten Hemmfaktoren (Antithrombin II, Progressiv-Antithrombin III), von denen nur das letztere auf die Fettmahlzeit eine Veränderung erfuhr und zwar im Sinne einer mehr oder minder starken Zunahme der Aktivität, die bei den fettungewohnten Vpn. besonders ausgeprägt war.

    Notes: Conclusion The ideas outlined in this paper are tentative and only partially developed. They have arisen very much as a response to the deficiencies in existing regional models. Whether this particular structure can lead to added order and power in such models remains to be demonstrated. But with increasing demands for analysis at a regional level, a substantial theoretical basis for regional models is manifestly needed.

    Description / Table of Contents: Summary Based upon four years of experience with weather radar at Berlin, the results of short-term precipitation forecasts are discussed. The difficulties of an interpretation of the screen picture due to certain secondary effects (attenuation absorption, tropospheric refraction) are emphasized. Some remarks pertain to the use of weather radar in meteorological pilot briefing.
    Abstract: Résumé L'auteur traite de problèmes relatifs à la prévision à courte échéance des précipitations sur la base de quatre ans d'emploi du radar à Berlin. Il expose les difficultés d'interprétation de l'image en raison d'effets secondaires (affaiblissement par la distance, pertes par absorption, réfraction troposphérique), mais il insiste avant tout sur les renseignements utiles à la prévision. Quelques remarques concernent l'emploi du radar dans les services météorologiques de l'aviation.
    Notes: Zusammenfassung Auf Grund von vierjährigen Erfahrungen mit dem Berliner Wetterradargerät werden Ergebnisse und Probleme der Niederschlagskurzfristprognose behandelt. Die Schwierigkeiten der Deutung des Radarbildes bezüglich gewisser Effekte (Streckendämpfung, Absorptionsverluste, troposphärische Strahlenbrechung) werden herausgestellt, doch werden nur Fragen behandelt, die mit der prognostischen Auslegung des Radarbild-Informationsgehaltes zusammenhängen. Einige Bemerkungen betreffen den Einsatz des Wetterradargerätes bei der meteorologischen Flugberatung.
