mulheres velhas (r)existem: algumas notas sobre a velhice feminina e sua presença na literatura brasileira do início do século XXI
Authors: Alves Cristiane da Silva
Published: October 2021

A partir do estudo de narrativas ficcionais da literatura brasileira publicadas nas primeiras décadas deste novo século, tem-se por objetivo investigar a presença das mulheres velhas, especialmente aquelas que se destacam como narradoras e/ou como protagonistas. Pretende-se observar se e como a literatura contemporânea tem contribuído para forjar determinadas identidades, ou antes, para reforçar ou (des)construir padrões e papéis comumente atribuídos à figura feminina envelhecida. Busca-se, sobretudo, contribuir para afastar ou minimizar os estereótipos e o silenciamento acerca da velhice feminina (ainda) presentes em nosso cânone. Para tanto, são tomados como corpus os romances Mar azul (Rocco, 2012), de Paloma Vidal; Amor em dois tempos (Companhia das Letras, 2014), de Lívia Garcia-Roza; Quarenta dias (Alfaguara, 2014) e Outros Cantos (Alfaguara, 2016), ambos de Maria Valéria Rezende. Para dar suporte às análises, recorre-se às contribuições de Simone de Beauvoir, Guita Grin Debert, Mirian Goldenberg, Ecléa Bosi e Regina Dalcastagnè, entre outros.

Ethiopian Jewish Ascetic Religious Communities
Authors: Kribus Bar
Published: October 2021

The Betä Isra'el (Ethiopian Jews) have a unique history and religious tradition, one of the most fascinating aspects of which are the mäloksocc, commonly referred to as monks in scholarly and popular literature. The mäloksocc served as the supreme religious leaders of the Betä Isra'el and were charged with educating and initiating Betä Isra'el priests. They lived in separate compounds and observed severe purity laws prohibiting physical contact with the laity. Thus, they are the only known example in medieval and modern Jewry of ascetic communities withdrawing from the secular world and devoting themselves fully to religious life.

This book presents the results of the first comprehensive research ever conducted on the way of life and material culture of the ascetic religious communities of the Betä Isra'el. A major part of this research is an archaeological survey, during which these religious centres were located and documented in detail for the first time.
Rethinking Authority in China’s Border Regime
Authors: Plümmer Franziska
Published: October 2021

In the 21st century, governments around the globe are faced with the question on how to tackle new migratory mobilities. Governments increasingly become aware of irregular immigration and are forced to re-negotiate the dilemma of open but secure borders. Rethinking Authority in China’s Border Regime: Regulating the Irregular investigates the Chinese government’s response to this phenomenon. Hence, this book presents a comprehensive analysis of the Chinese border regime. It explores the regulatory framework of border mobility in China by analysing laws, institutions, and discourses as part of an ethnographic border regime analysis. It argues that the Chinese state deliberately creates ‘zones of exception’ along its border. In these zones, local governments function as ‘scalar managers’ that establish cross-border relations to facilitate cross-border mobility and create local migration systems that build on their own notion of legality by issuing locally valid border documents. The book presents an empirically rich story of how border politics are implemented and theoretically contributes to debates on territoriality and sovereignty as well as to the question of how authority is exerted through border management. Empirically, the analysis builds on two case studies at the Sino-Myanmar and Sino-North Korean borders to illustrate how local practices are embedded in multiscalar mobility regulation including regional organizations such as the Greater Mekong Subregion and the Greater Tumen Initiative.
A Metropolitan History of the Dutch Empire
Authors: Kuipers Matthijs
Published: October 2021

A Metropolitan History of the Dutch Empire: Popular Imperialism in The Netherlands, 1850-1940 examines popular imperial culture in the Netherlands around the turn of the twentieth century. In various and sometimes unexpected places in civil society the empire played a prominent role and was key in mobilizing people for causes that were directly and indirectly related to the Dutch overseas colonies. At the same time, however, the empire was ostensibly absent from people's minds. Except for some jingoist outbursts during the Aceh War and the Boer War, indifference was the main attitude with which imperial affairs were greeted. How could the empire simultaneously be present and absent in metropolitan life? Drawing upon the works of scholars from fields ranging from postcolonial studies to Habsburg imperialism, the author argues that indifference to empire was not an anomaly to the idea of an all-permeating imperial culture, but rather the logical consequence of an imperial ideology that rendered metropole and colony firmly separated entities. The different groups and individuals that advocated imperial or anti-imperial causes – such as missionaries, former colonials, Indonesian students, and boy scouts – hardly ever related to each other explicitly and had their own distinctive modes of expression, but were nonetheless part of what the author calls a 'fragmented empire' and shared the common thread of Dutch imperial ideology. This suggests we should not mistake colonial culture's metropolitan invisibility for a lack of strength.

Sanierputzsysteme.
Authors: Meier Hermann G. , Stürmer Sylvia
Published: October 2021

Sanierputzsysteme wurden für feuchtes, salzbelastetes Mauerwerk entwickelt. Richtig angewendet ermöglichen sie langfristig schadenfreie Putzflächen auf problematischen Untergründen. Leider kommen immer wieder Fehlanwendungen vor. Es treten Flecken und Ausblühungen auf, der Putz wird zerstört, weil grundlegende Voraussetzungen für die Planung und Ausführung missachtet wurden. Dieses Buch vermittelt das notwendige Grundwissen für die Vermeidung solcher Fehler. Sanierputzsysteme bestehen in der Regel aus dem Spritzbewurf, dem Sanierputz als Grundputz und einem Oberputz oder einem Farbanstrich. Diese Materialien müssen genau aufeinander abgestimmt werden, damit sie in der Lage sind, Salze aufzunehmen und Feuchtigkeit zu speichern. Außerdem müssen sie zum jeweiligen Untergrund passen. Vorhandene Salzbelastung, Durchfeuchtungsgrad, Tragfähigkeit des Putzgrunds, Saug- und Trocknungsverhalten sind nur einige der Eigenschaften, an die das System angepasst werden muss. Diese komplexen Zusammenhänge zwischen Untergrund und Putzmörteleigenschaften sind wissenschaftlich gut erforscht und in den technischen Regelwerken berücksichtigt. Die Autoren bereiten dieses Wissen für die praktische Anwendung auf. Mit anschaulichen Erklärungen und aussagekräftigen Bilder gelingt es ihnen, die komplexen Schadensmechanismen von Putzen und Mauerwerk darzustellen und die Funktionsweise von Sanierputzsystemen zu erklären. Das Buch enthält alle Informationen, die Planer und Ausführende für die Herstellung dauerhafter Putze auf problematischen Untergründen benötigen, einschließlich der Lösungen für die besonders schwierigen Gebäudesockel und denkmalgeschützte Fassaden.

Published: October 2021

Die räumlichen und hygienischen Bedingungen vieler Schulen erfüllen nicht mehr die heutigen Erwartungen. Zudem weisen die Gebäude einen hohen Energieverbrauch auf und belasten damit den Haushalt der Kommunen. In der Bevölkerung besteht Konsens, dass Schulen für die gesellschaftliche Zukunft eine hohe Bedeutung haben.

Mit der Forschungsinitiative »Energieeffiziente Schulen - EnEff:Schule« förderte das Bundesministerium für Wirtschaft und Energie (BMWi) ein Vorhaben, bei dem gezeigt wurde, wie Schulgebäude das energetische Niveau einer 3-Liter-Haus-Schule oder einer Plusenergieschule erreichen können. Neben der energetischen Sanierung von zum Teil 50 Jahre alten Schulgebäuden wurden auch Schulneubauten erstellt. Die umgesetzten Beispiele zeigen, wie durch heute verfügbare technische und bauliche Innovation der Primärenergiebedarf für Heizung, Lüftung, Kühlung, Trinkwarmwassererwärmung und Beleuchtung wirtschaftlich gesenkt werden kann. Eine Begleitforschung hat alle Projekte intensiv begleitet, die Messergebnisse ausgewertet, dokumentiert und die Daten in Querauswertungen einander gegenübergestellt. Ferner fanden Befragungen der Schülerinnen und Schüler sowie der Lehrerinnen und Lehrer vor und nach der Sanierung statt.

Anhand der ermittelten Daten und Erkenntnisse konnten umfangreiche Empfehlungen zusammengestellt werden, die sowohl für die Sanierung als auch für den Schulneubau hilfreich sind. Für alle Personen und Institutionen, die bei der Planung eines Schulneubaus oder der Sanierung eines Schulgebäudes eingebunden sind, enthält dieses Buch wertvolle Informationen.

Published: October 2021

To enhance the competitiveness of colleges and universities in the graduate enrollment and reduce the pressure on candidates for examination and consultation, it is necessary and practically significant to develop an intelligent Q&A platform, which can understand and analyze users' semantics and accurately return the information they need. However, there are problems such as the low volume and low quality of the corpus in the graduate enrollment, this paper develops a question answering platform based on a novel retrieval model including density-based logistic regression and the combination of convolutional neural networks and bidirectional long short-term memory. The experimental results show that the proposed model can effectively alleviate the problem of data sparseness and greatly improve the accuracy of the retrieval performance for the graduate enrollment.

Databases are vulnerable. Public statements by Target, Home Depot, and Anthem following their extremely advertised data breaches are each uniform and succinct on how their breaches unfolded: unauthorized access to those systems that ultimately led to the extraction of sensitive information. A comprehensive strategy to secure a database is over data security. Usually, security events will be related to the later action: illegitimate access to data confidentiality damage, injury to the integrity of knowledge, loss of data accessibility (Discover). Loss of privacy of data, creating them accessible to others without a right of access is not visible within the database and does not need changes deductible database. This paper addresses these events to confirm database security.

Post Covid-19 and Dentistry Revealing the silent condition - Rhino Maxillary Mucormycosis
Authors: Rana Anju , Tandon Shruti , Kaur Arundeep , Faraz Farrukh , Agarwal Kamal
Published: October 2021

The author would like to highlight the uncommon condition of rhinomaxillary mucormycosis which presents with a common complaint of periodontal abscess. This is highly significant in the current global scenario of the Covid-19 pandemic, as this deadly condition if diagnosed timely (by the dental surgeon) can save lives and prevent serious lifelong morbidity. Acute lung damage in Covid-19 was controlled worldwide by administering corticosteroids. This led to transient hyperglycemia, which coupled with low immunity served as an ideal environment for the fungal spore’s growth and proliferation.1 Species like Candida, Aspergillus and Rhizopus are normally not virulent in healthy individuals but can cause disseminated fatal infections in an immune-compromised host.2 Infection caused by these opportunistic pathogenic fungi present with non-specific symptoms and are often difficult to diagnose. Mucormycosis is the third most common opportunistic fungal infection caused by Rhizopus.3 Two such cases reported to the Department of Periodontics, Maulana Azad Institute of Dental Sciences, New Delhi with similar oral findings and common history of Covid-19 recovery. Both the patients were on 3 weeks of steroid therapy during which they had transient hyperglycemia. After 4 weeks of recovery, they developed painful gum boil/s. Clinical findings revealed periodontal abscess and tooth mobility.

Conceptul lovinescian de „intelectualizare” a literaturii față cu ipoteza postbelică a țăranului „intelectualizat”
Authors: Dumitru Teodora
Published: October 2021

In this essay I investigate the multiple and ambiguous ways in which the Romanian critic Eugen Lovinescu instrumentalized one hundred years ago the concept of „intellectualization” regarding the process of Romanian literature evolution towards modernity, a process associated with abandoning its rural roots in order to become thematically more urbane oriented. I also investigate the polemical echoes of Lovinescu’s action during the Interwar period and after, especially during the Communist era (1948-89), when his texts and thesis were largely deformed in order to both subvert and accommodate the Communist regime agenda towards peasant and rural literature.
Ciprian Porumbescu. Mică poveste despre rochia Berthei (o incursiune printre manuscrise, ediții etc.)
Authors: Diaconu Mircea
Published: October 2021

A young Romanian composer from the Austrian Bucovina, Ciprian Porumbescu (1853-1883) is an important figure of the local cultural mythology. This fact, we believe, is due to the association of his image with some ill-fated aspects of his life, such as an impossible love, his premature death, his exultant talent, maybe even his ardent patriotism. In my attempts at recovering the past cultural life of Bucovina, I discovered the journal of Ciprian Porumbescu (that probably includes a rich correspondence as well), written around 1878-1883. I am not talking about a journal on creation, nor about one related to political life. That, in spite of the fact that he was arrested for being the president of a student’s society that had a nationalist nature, yet he didn’t hesitate afterwards being one of the leaders of an international German society. Unfortunately, the above mentioned journal is absent from the public space and the history of its recovery and editing is in itself a history of a failure. That is why, this study is an analysis of the different existing editions of it – that could be described as fragmented, or improvised. In what regards the title of the article, it hints at the imprecisions in transcribing the original text, the difficulties posed by the German existing versions and also at the deficiency of the Romanian translations. Yet, besides all of these, the journal of Ciprian Porumbescu is an exceptional biographical document. Thus, the critique of the existing editions could represent a fist attempt at a textual and analytical recovery of the actual journal.
Les conversations personnelles dans les bureaux à aire ouverte
Authors: Bolduc Mariane , Gendron Audrey , Montreuil Megan , Bénard Charlélie , Vachon François
Published: October 2021

Dans les bureaux à aire ouverte, les conversations en arrière-plan influencent négativement le bien-être des employés ainsi que leur performance sur des tâches quotidiennes. Des résultats récents suggèrent d’ailleurs que la nature personnelle des conversations amplifie leur pouvoir distracteur, d’où l’importance de la présente étude visant à vérifier à quel point ce type de conversation est dérangeant. Pour ce faire, l’impact distracteur des conversations personnelles est examiné dans un contexte cognitivement exigeant, soit l’utilisation d’une police d’écriture « disfluente » (c.-à-d. plus difficile à lire), un facteur reconnu comme ayant un effet protecteur contre la distraction auditive. Ainsi, 60 participants effectuent une tâche de bureau avec police disfluente et 60 autres avec une police fluente sous trois conditions sonores : silence, dialogue (les deux interlocuteurs d’une conversation sont entendus) et demilogue (un seul des deux interlocuteurs est entendu). Les résultats montrent que l’utilisation d’une police disfluente, comparativement à celle fluente, ne diminue pas la quantité de distraction produite par les conversations. Ces résultats suggèrent que les conversations personnelles sont particulièrement distrayantes. Ce pouvoir distracteur accru découlerait de l’aspect intrigant qui est inhérent au contenu de ce type de conversation et qui susciterait un besoin (volontaire) d’écouter la conversation.

The measurement ranges were 20 kV to 100 kV DC and 15-70 kV RMS at 60 Hz AC. The ILC was designed to verify strengths and reveal weaknesses in high voltage measurements in commercial, military and energy sector calibration laboratories. The ILC was performed among members of NCSL International, with the generous support of National Research Council Canada (NRC).
Characterizations of Europe's integrated water vapor and assessments of atmospheric reanalyses using more than two decades of ground-based GPS
Authors: Yuan Peng , Van Malderen Roeland , Yin Xungang , Vogelmann Hannes , Awange Joseph , Heck Bernhard , Kutterer Hansjörg
Published: October 2021

Abstract. Ground-based Global Positioning System (GPS) has been extensively used to retrieve Integrated Water Vapor (IWV) and has been adopted as a unique tool for the assessments of atmospheric reanalyses. In this study, we investigated the multi-temporal-scale variabilities and trends of IWV over Europe by using IWV time series from 108 GPS stations for more than two decades (1994–2018). We then adopted the GPS IWV as a reference to assess six commonly-used atmospheric reanalyses, namely CFSR, ERA5, ERA-Interim, JRA55, MERRA2, and NCEP2. The GPS results show that the diurnal cycles peak within 16:00–24:00 local time with peak-to-peak amplitudes accounting for 2 %–18 % of the daily mean. The diurnal 1-hourly anomalies can be much more intensive with a range of −100 % to 200 %. The annual cycles peak in July and August with maximum values of 17–32 kg m−2. The interannual variations of IWV over Europe are found to be mainly linked to the North Atlantic Oscillation (NAO) and the East Atlantic (EA) patterns. The IWV continues to increase over Europe during the last two decades at 0–0.4 kg m−2 decade−1 in the north and 0.4–1 kg m−2 decade−1 in the south. Regarding the assessments of the reanalyses, the intercomparisons with respect to GPS reveal a general superiority of the newly-released ERA5 IWV product. For instance, ERA5 only has a slight wet bias with a median value of 1 %, whereas the median bias for MERRA2 is 4 %. ERA5, MERRA2, and NCEP2 are the best, second best, and worst performers respectively in modelling the variability of daily IWV time series, with standard deviations of daily IWV differences against GPS by 0.5–1.6, 0.7–2.3, and 1.2–3.0 kg m−2, respectively. Moreover, the daily GPS IWV time series is best correlated with the ERA5 IWV with a median Pearson correlation coefficient of 0.996, whereas the second strongest and weakest median correlations are observed in MERRA2 and NCEP2 with values of 0.991 and 0.971, respectively. Furthermore, the correlations between the IWV trends from the reanalyses and GPS are strongest for ERA5 (0.82), a bit weaker for MERRA2 (0.72), and weakest for NCEP2 (0.52).
Decay times of atmospheric acoustic-gravity waves after deactivation of wave forcing
Authors: Gavrilov Nikolai M. , Kshevetskii Sergey P. , Koval Andrey V.
Published: October 2021

Abstract. High-resolution numerical simulations of non-stationary nonlinear acoustic-gravity waves (AGWs) propagating upwards from surface wave sources are performed for different temporal intervals relative to activation/deactivation times of the wave forcing. After activating surface wave sources, amplitudes of AGW spectral components reach a quasi-stationary state. Then the surface wave forcing is deactivated in the numerical model, and amplitudes of vertically traveling AGW modes quickly decrease at all altitudes due to discontinuations of the upward propagation of wave energy from the wave sources. However, later the standard deviation of residual and secondary wave perturbations experiences slower quasi-exponential decrease. High-resolution simulations allowed, for the first time, estimating the decay times of this wave noise produced by slow residual, quasi-standing and secondary AGW spectral components, which vary between 20 and 100 hrs depending on altitude and the rate of wave source activation/deactivation. The standard deviations of the wave noise are larger for the case of sharp activation/deactivation of the wave forcing compared to the steep processes. These results show that transient wave sources may create long-lived wave perturbations, which can form a background level of wave noise in the atmosphere. This should be taken into account in parameterizations of atmospheric AGW impacts.

Abstract. Quantitative reconstructions of past land-cover are necessary for research into the processes involved in climate-human-land interactions. We present the first temporally continuous pollen-based land-cover reconstruction for Europe over the Holocene (last 11,700 cal yr BP). We describe how vegetation cover has been quantified from pollen records at a 1° × 1° spatial scale using the ‘Regional Estimates of VEgetation Abundance from Large Sites’ (REVEALS) model. REVEALS has been applied to 1128 pollen records across Europe and part of the Eastern Mediterranean-Black Sea-Caspian-Corridor (30°–75° N, 25° W–50° E) to reconstruct the cover of 31 plant taxa assigned to 12 plant functional types (PFTs) and three land-cover types (LCTs). A new synthesis of relative pollen productivities (RPPs) available for European plant taxa was performed for this reconstruction. It includes > 1 RPP values for 39 taxa, and single values for 15 taxa (total of 54 taxa). As an illustration, we present maps of the results for five taxa (Calluna vulgaris, Cerealia-t, Picea abies, Quercus deciduous and Quercus evergreen) and three LCTs (open land (OL), evergreen trees (ET) and summer-green trees (ST)) for 8 selected time windows. We discuss the reliability of the REVEALS reconstructions and issues related to the interpretation of the results in terms of landscape openness and human-induced vegetation change. We then describe the current use of this reconstruction and its future potential utility and development.

Towards improved analysis of short mesoscale sea level signals from satellite altimetry
Authors: Quilfen Yves , Piolle Jean-François , Chapron Bertrand
Published: October 2021

Abstract. Satellite altimeters routinely supply sea surface height (SSH) measurements, which are key observations for monitoring ocean dynamics. However, below a wavelength of about 70 km, along-track altimeter measurements are often characterized by a dramatic drop in signal-to-noise ratio, making it very challenging to fully exploit the available altimeter observations to precisely analyze small mesoscale variations in SSH. Although various approaches have been proposed and applied to identify and filter noise from measurements, no distinct methodology has emerged for systematic application in operational products. To best address this unresolved issue, the Copernicus Marine Environment Monitoring Service (CMEMS) actually provides simple band-pass filtered data to mitigate noise contamination of along-track SSH signals. More innovative and suitable noise filtering methods are thus left to users seeking to unveil small-scale altimeter signals. As demonstrated here, a fully data-driven approach is developed and applied successfully to provide robust estimates of noise-free Sea Level Anomaly (SLA) signals. The method combines Empirical Mode Decomposition (EMD), to help analyze non-stationary and non-linear processes, and an adaptive noise filtering technique inspired by Discrete Wavelet Transform (DWT) decompositions. It is found to best resolve the distribution of SLA variability in the 30–120 km mesoscale wavelength band. A practical uncertainty variable is attached to the denoised SLA estimates that accounts for errors related to the local signal-to-noise ratio, but also for uncertainties in the denoising process, which assumes that the SLA variability results in part from a stochastic process. For the available period, measurements from the Jason-3, Sentinel-3 and Saral/AltiKa missions are processed and analyzed, and their energy spectral and seasonal distributions characterized in the small mesoscale domain. In anticipation of the upcoming SWOT (Surface Water and Ocean Topography) mission data, the SASSA data set (Satellite Altimeter Short-scale Signals Analysis, Quilfen and Piolle, 2021) of denoised SLA measurements for three reference altimeter missions already yields valuable opportunities to evaluate global small mesoscale kinetic energy distributions.

Abstract. A new dynamical core, known as the Finite Volume Cubed-Sphere (FV3) and developed at both NASA and NOAA, is used in NOAA’s Global Forecast System (GFS) and in limited area models (LAMs) for regional weather and air quality applications. NOAA has also upgraded the operational FV3GFS to version 16 (GFSv16), and includes a number of significant developmental advances to the model configuration, data assimilation, and underlying model physics, particularly for atmospheric composition to weather feedback. Concurrent with the GFSv16 upgrade, we couple the GFSv16 with the Community Multiscale Air Quality (CMAQ) model to form an advanced version of the National Air Quality Forecast Capability (NAQFC) that will continue to protect human and ecosystem health in the U.S. Here we describe the development of the FV3GFSv16 coupling with a “state-of-the-science” CMAQ model version 5.3.1. The GFS-CMAQ coupling is made possible by the seminal version of the NOAA-ARL Atmosphere-Chemistry Coupler (NACC), which became the next operational NAQFC system (i.e., NACC-CMAQ) on July 20, 2021. NACC-CMAQ has a number of scientific advancements that include satellite- based data acquisition technology to improve land cover and soil characteristics, and inline wildfire smoke and dust predictions that are vital to predictions of fine particulate matter (PM2.5) concentrations during hazardous events affecting society, ecosystems, and human health. The GFS-driven NACC-CMAQ has significantly different meteorological and chemical predictions than the previous operational NAQFC, where evaluation of NACC-CMAQ shows generally improved near-surface ozone and PM2.5 predictions and diurnal patterns, both of which are extended to a 72-hour (3-day) forecast with this system.

Abstract. Hillslope similarity is an active topic in hydrology because of its importance to improve our understanding of hydrologic processes and enable comparisons and paired studies. In this study, we propose a holistic bottom-up hillslope similarity classification based on a region’s integrative hydrodynamic response quantified by the seasonal changes in groundwater levels. The main advantage of the proposed classification is its ability to describe recharge and discharge processes. We test the performance of the proposed classification by comparing it to seven other common hillslope similarity classifications. These include simple classifications based on the aridity index, topographic wetness index, elevation, land cover, and more sophisticated machine-learning classifications that jointly integrate all these data. We assess the ability of these classifications to identify and categorize hillslopes with similar static characteristics, hydroclimatic behaviors, land surface processes, and subsurface dynamics in a mountainous watershed, the East River, located in the headwaters of the Upper Colorado River Basin. The proposed classification is robust as it reasonably identifies and categorizes hillslopes with similar elevation, land cover, hydroclimate, land surface processes, and subsurface hydrodynamics (and hence hillslopes with similar hydrologic function). In general, the other approaches are good in identifying similarity in a single characteristic, which is usually close to the selected variable. We further demonstrate the robustness of the proposed classification by testing its ability to predict hillslope responses to wet and dry hydrologic conditions, of which it performs well when based on average conditions.
Research on a cascade model synthesis with the use of classical and non-classical methods in the context of new piezoelectric stack applications
Authors: Harazin Jacek , Wróbel Andrzej
Published: October 2021

Abstract. Active audio noise cancellation technology using piezoelements is fairly new and emerging technology on the market in recent years and is still gaining in popularity. The ability to use piezoelectric devices to gather information about vibration spectrum and to create interfering waves, to cancel out the noise, allows for the reduction in passive vibration methods and gives more flexibility in terms of space and application. The idea of using this technique on larger scales such as industrial equipment is the focus of ongoing research conducted by the authors of this article. This work is intended as the first part of a larger project and focuses solely on theoretical approach to the problem of modelling mechatronic systems capable of creating complex vibration spectrums and using piezoelectric components. The authors have focused on creating a mix of classical and non-classical methods to synthesize model systems based on input resonance frequencies. A classical calculation through matrix equations was also done to validate the accuracy of obtained results through the structural number method. The resulting model is still awaiting the empirical verification through extensive testing on real-life models, and that part of the research is still being developed. When validated and checked, this technology could bring new solutions in the vibration damping of industrial equipment, potentially increasing its flexibility and effectiveness.
Decadal sea-level variability in the Australasian Mediterranean Sea
Authors: Wagner Patrick , Böning Claus W.
Published: October 2021

Abstract. Strong regional sea-level trends, mainly related to basin-wide wind stress anomalies, have been observed in the western tropical Pacific over the last 3 decades. Analyses of regional sea level in the densely populated regions of the neighbouring Australasian Mediterranean Sea (AMS; also called tropical Asian seas) are hindered by its complex topography and respective studies are sparse. We used a series of global eddy-permitting ocean models, including a high-resolution configuration that resolves the AMS with 120∘ horizontal resolution, forced by a comprehensive atmospheric forcing product over 1958–2016 to characterize the patterns and magnitude of decadal sea-level variability in the AMS. The nature of this variability is elucidated further by sensitivity experiments with interannual variability restricted to either the momentum or buoyancy fluxes, building on an experiment employing a repeated-year forcing without interannual variability in all forcing components. Our results suggest that decadal fluctuations of the El Niño–Southern Oscillation (ENSO) account for over 80 % of the variability in all deep basins of the region, except for the central South China Sea (SCS). Changes related to the Pacific Decadal Oscillation (PDO) are most pronounced in the shallow Arafura and Timor seas and in the central SCS. On average, buoyancy fluxes account for less than 10 % of decadal SSH variability, but this ratio is highly variable over time and can reach values of up to 50 %. In particular, our results suggest that buoyancy flux forcing amplifies the dominant wind-stress-driven anomalies related to ENSO cycles. Intrinsic variability is mostly negligible except in the SCS, where it accounts for 25 % of the total decadal SSH variability.
Interdisciplinary Fracture Network Characterization in the Crystalline Basement: A case study from the Southern Odenwald, SW Germany

Published: October 2021

Abstract. The crystalline basement is considered a ubiquitous and almost inexhaustible source of geothermal energy in the Upper Rhine Graben and other regions worldwide. The hydraulic properties of the basement, which are one of the key factors for the productivity of geothermal power plants, are primarily controlled by hydraulically active faults and fractures. While the most accurate in situ information about the general fracture network is obtained from image logs of deep boreholes, such data are generally sparse, costly and thus often not openly accessible. To circumvent this problem, an outcrop analogue study with interdisciplinary geoscientific methods was conducted in the Tromm Granite, located in the southern Odenwald at the northeastern margin of the URG. Using LiDAR scanning, the key characteristics of the fracture network were extracted in a total of five outcrops, additionally complemented by lineament analysis of two different digital elevation models. Based on this, discrete fracture network (DFN) models were developed to calculate equivalent permeability tensors under assumed reservoir conditions. The influence of different parameters, such as fracture orientation, density, aperture and mineralization was investigated. In addition, extensive gravity and radon measurements were carried out in the study area, allowing for more precise localization of fault zones with naturally increased porosity and permeability. Gravity anomalies served as input data for a stochastic density inversion, through which areas of increased open porosity were identified. A laterally heterogeneous fracture network characterizes the Tromm Granite, with the highest natural permeabilities expected at the pluton margin, due to the influence of large shear and fault zones.
Poetics of the Uncanny: A Post-Phenomenological Critique of D. H. Lawrence and Somerset Maugham’s Short Fiction
Authors: Shehzad Umar
Published: October 2021

Taking issue with Sigmund Freud’s premise on the subject, this essay seeks alternately to inquire into, challenge, and broaden our understanding of the uncanny. Even though this genius from the field of psychoanalysis is quite right in wreathing the uncanny with the murky aura that it wears to date, his insistence on driving one way traffic from heimlich to das unheimliche while at the same time refusing to let it out of “the realm of the frightening” gives a kind of staleness and fixity to the subject of the uncanny, which is no less than its undoing, especially when it comes to its artistic representation. Eschewing psychoanalytical debates and focusing rather upon the post-phenomenological discourse, I’ll show as to how the homely artistic devices like paradox, reversal, thematic and narrative flux, unswerving matter-of-factness yield an uncanny import in “The Rocking-Horse Winner” and “The Book Bag,” the two short stories by Lawrence and Maugham respectively. Insisting upon the essential uncanniness of art, this article proposes that the uncanny hinges on what Martin Seel (2005) describes as art’s fundamental “irreality” and Theodor Adorno (1973) calls “appearances”. I hypothesize that the uncanny owes its life to a continual movement of the subject matter between openness and closure, between imagination and reality, between the outer world and the inner domain, between what Bhabha (1992) alludes to as the world and the home.
