Effects of the Chinese herbal formula San-Huang Gu-Ben Zhi-Ke treatment on stable chronic obstructive pulmonary disease: study protocol of a randomized, double-blind, placebo-controlled trial
Authors: Zu Yaqi , Li Demin , Lei Xiang , Zhang Hongchun
Published: November 2019

Background

Due to the large number of patients, high mortality rate as well as high social costs and economic burden, chronic obstructive pulmonary disease (COPD) has become one of the most important health problems around the world, which has attracted people’s attention. Currently, Chinese herbs have been widely used as alternative medicine (CAM) for COPD patients. The Chinese herbal formula San-Huang Gu-Ben Zhi-Ke (SHGBZK) has shown good clinical efficacy in COPD in preclinical studies. Animal experiments have shown that it has mucosal immune barrier function and can maintain airway wall integrity, reduce inflammatory cell infiltration, promote inflammatory damage repair, and relieve narrow airway conditions.

Methods/design

This study is a randomized, double-blind, placebo-controlled trial. A total of 100 patients with stable COPD diagnosed with deficiency of lung qi and spleen qi will be recruited and randomly assigned to one of two treatment groups: SHGBZK treatment, N = 50; placebo treatment, N = 50. The two groups will receive basic treatment for COPD according to the 2017 GOLD Guidelines for Chronic Obstructive Pulmonary Disease. Patients will stick to the treatment they used to take as much as possible, and will be given present general treatment when acute exacerbation of COPD occurs during the study. Both groups will receive a 24-week intervention and patient status will be assessed at 24 weeks and then 28 weeks after treatment. After the 24-week treatment, patients will be followed up for another 28 weeks. Outcome measures, including the frequency and duration of acute exacerbation, lung function, traditional Chinese medicine symptom score, exercise capacity, and quality of life will be assessed.

Discussion

It is hypothesized that SHGBZK will have beneficial effects in reducing the frequency and duration of acute exacerbations, improving the exercise capacity function of patients with stable COPD diagnosed with a deficiencies in lung qi and spleen qi. This study may establish a new treatment method for COPD patients, differentiating it from other drugs in clinical use used for similar clinical indications.

Published: November 2019

Background

Reunion Island regularly faces outbreaks of epizootic haemorrhagic disease (EHD) and bluetongue (BT), two viral diseases transmitted by haematophagous midges of the genusCulicoides(Diptera: Ceratopogonidae) to ruminants. To date, five species ofCulicoidesare recorded in Reunion Island in which the first two are proven vector species:Culicoides bolitinos,C. imicola,C. enderleini,C. grahamiiandC. kibatiensis. Meteorological and environmental factors can severely constrainCulicoidespopulations and activities and thereby affect dispersion and intensity of transmission ofCulicoides-borne viruses. The aim of this study was to describe and predict the temporal dynamics of allCulicoidesspecies present in Reunion Island.

Methods

Between 2016 and 2018, 55 biweeklyCulicoidescatches using Onderstepoort Veterinary Institute traps were set up in 11 sites. A hurdle model (i.e. a presence/absence model combined with an abundance model) was developed for each species in order to determine meteorological and environmental drivers of presence and abundance ofCulicoides.

Results

Abundance displayed very strong heterogeneity between sites. AverageCulicoidescatch per site per night ranged from 4 to 45,875 individuals.Culicoides imicolawas dominant at low altitude andC. kibatiensisat high altitude. A marked seasonality was observed for the three other species with annual variations. Twelve groups of variables were tested. It was found that presence and/or abundance of all fiveCulicoidesspecies were driven by common parameters: rain, temperature, vegetation index, forested environment and host density. Other parameters such as wind speed and farm building opening size governed abundance level of some species. In addition,Culicoidespopulations were also affected by meteorological parameters and/or vegetation index with different lags of time, suggesting an impact on immature stages. Taking into account all the parameters for the final hurdle model, the error rate by Normalized Root mean Square Error ranged from 4.4 to 8.5%.

Conclusions

To our knowledge, this is the first study to modelCulicoidespopulation dynamics in Reunion Island. In the absence of vaccination and vector control strategies, determining periods of high abundance ofCulicoidesis a crucial first step towards identifying periods at high risk of transmission for the two economically important viruses they transmit.

Published: November 2019

Background

Ankylosing spondylitis (AS) shares many characteristics with inflammatory bowel disease (IBD). Intestinal microbiota most likely plays an important role in the development of IBDs and may also be involved in the pathogenesis of AS. We aimed to define and compare the fecal microbiota composition in patients with AS, ulcerative colitis (UC), and healthy controls (HC) and to determine relationships between fecal microbiota, fecal calprotectin, and disease-related variables in AS.

Methods

Fecal microbiota composition was assessed with GA-map™ Dysbiosis Test (Genetic Analysis, Oslo, Norway), which also reports the degree of deviation of the microbiota composition compared with a healthy control population, a Dysbiosis Index (DI) score 1–5. The AS patients were assessed with questionnaires, back mobility tests, fecal calprotectin, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).

Results

Totally, 150 patients with AS (55% men, median age 55.5 years, median BASDAI 3.2), 18 patients with UC (56% men, median age 30.5 years), and 17 HC (65% men, median age 22 years) were included. Principal component analysis showed highly separate clustering of fecal microbiota from the patients with AS, UC, and HC. Compared with HC, fecal microbiota in AS was characterized by a higher abundance of Proteobacteria, Enterobacteriaceae, Bacilli, Streptococcus species, and Actinobacteria, but lower abundance of Bacteroides and Lachnospiraceae.

Further, fecal microbiota composition differed between patients with normal (≤ 50 mg/kg, n = 57) and increased (≥ 200 mg/kg, n = 36) fecal calprotectin. Patients with increased fecal calprotectin had lower abundance of bacteria with anti-inflammatory properties such as Faecalibacterium prausnitzii and Clostridium and higher abundance of the genus Streptococcus. No association was found between the fecal microbiota composition and HLAB27 status, disease activity, function, or medication. Dysbiosis (defined as DI ≥ 3) was found in 87% of AS patients.

Conclusions

Patients with AS have a distinct fecal microbiota signature, which is linked to fecal calprotectin levels, a marker of intestinal inflammation, but not to other clinical parameters. These findings suggest a local interplay between intestinal microbiota and gut inflammation in AS.

Semantic connection set-based massive RDF data query processing in Spark environment
Authors: Xu Jiuyun , Zhang Chao
Published: November 2019

Resource Description Framework (RDF) is a data representation of the Semantic Web, and its data volume is growing rapidly. Cloud-based systems provide a rich platform for managing RDF data. However, there is a performance challenge in the distributed environment when RDF queries, which contain multiple join operations, such as network reshuffle and memory overhead, are processed. To get over this challenge, this paper proposes a Spark-based RDF query architecture, which is based on Semantic Connection Set (SCS). First of all, the proposed Spark-based query architecture adopts the mechanism of re-partitioning class data based on vertical partitioning, which can reduce memory overhead and spend up index data. Secondly, a method for generating query plans based on semantic connection set is proposed in this paper. In addition, some statistics and broadcast variable optimization strategies are introduced to reduce shuffling and data communication costs. The experiments of this paper are based on the latest SPARQLGX on the Spark platform RDF system. Two synthetic benchmarks are used to evaluate the query. The experiment results illustrate that the proposed approach in this paper is more efficient in data search than contrast systems.
A new Internet of Things architecture for real-time prediction of various diseases using machine learning on big data environment
Authors: Ed-daoudy Abderrahmane , Maalmi Khalil
Published: November 2019

A number of technologies enabled by Internet of Thing (IoT) have been used for the prevention of various chronic diseases, continuous and real-time tracking system is a particularly important one. Wearable medical devices with sensor, health cloud and mobile applications have continuously generating a huge amount of data which is often called as streaming big data. Due to the higher speed of the data generation, it is difficult to collect, process and analyze such massive data in real-time in order to perform real-time actions in case of emergencies and extracting hidden value. using traditional methods which are limited and time-consuming. Therefore, there is a significant need to real-time big data stream processing to ensure an effective and scalable solution. In order to overcome this issue, this work proposes a new architecture for real-time health status prediction and analytics system using big data technologies. The system focus on applying distributed machine learning model on streaming health data events ingested to Spark streaming through Kafka topics. Firstly, we transform the standard decision tree (DT) (C4.5) algorithm into a parallel, distributed, scalable and fast DT using Spark instead of Hadoop MapReduce which becomes limited for real-time computing. Secondly, this model is applied to streaming data coming from distributed sources of various diseases to predict health status. Based on several input attributes, the system predicts health status, send an alert message to care providers and store the details in a distributed database to perform health data analytics and stream reporting. We measure the performance of Spark DT against traditional machine learning tools including Weka. Finally, performance evaluation parameters such as throughput and execution time are calculated to show the effectiveness of the proposed architecture. The experimental results show that the proposed system is able to effectively process and predict real-time and massive amount of medical data enabled by IoT from distributed and various diseases.
A One Health perspective to identify environmental factors that affect Rift Valley fever transmission in Gezira state, Central Sudan
Authors: Bashir Rania Salah Eldien , Hassan Osama Ahmed
Published: November 2019

Background

Rift Valley fever (RVF) is a zoonotic viral vector-borne disease that affects both animals and humans and leads to severe economic consequences. RVF outbreaks are triggered by a favorable environment and flooding, which enable mosquitoes to proliferate and spread the virus further. RVF is endemic to Africa and has spread to Saudi Arabia and Yemen. There is great concern that RVF may spread to previously unaffected geographic regions due to climate change. We aimed to better understand the spatiotemporal pattern of the 2007 RVF outbreak at the human–animal–environment interface and to determine environmental factors that may have effects on RVF occurrence in Gezira state, Sudan.

Materials and methods

We compiled epidemiological, environmental, and spatiotemporal data across time and space using remote sensing and a geographical information system (GIS). The epidemiological data included 430 RVF human cases as well as human and animal population demographic data for each locality. The cases were collected from 41 locations in Gezira state. The environmental data represent classified land cover during 2007, the year of the RVF outbreak, and the average of the Normalized Difference Vegetation Index (NDVI) for 6 months of 2007 is compared with those of 2010 and 2014, when there was no RVF outbreak. To determine the effect of the environmental factors such as NDVI, soil type, and RVF case’s location on the Blue Nile riverbank on RVF incidence in Gezira state, a multilevel logistic regression model was carried out.

Results

We found that the outbreak in Gezira state occurred as a result of interaction among animals, humans, and the environment. The multilevel logistic regression model (F = 43,858, df = 3,p = 0.000) explained 23% of the variance in RVF incidence due to the explanatory variables. Notably, soil type (β = 0.613,t = 11.284,p = 0.000) and NDVI (β = − 0.165,t = − 3.254,p = 0.001) were the explanatory environmental factors that had significant effects on RVF incidence in 2007 in Gezira state, Sudan.

Conclusions

Precise remote sensing and the GIS technique, which rely on environmental indices such as NDVI and soil type that are satellite-derived, can contribute to establishing an early warning system for RVF in Sudan.

Future preparedness and strengthening the capacity of regional laboratories are necessary for early notification of outbreaks in animals and humans.
Perinatal mental health around the world: priorities for research and service development in Sweden
Authors: Wickberg Birgitta , Bendix Marie , Wetterholm Margareta Blomdahl , Skalkidou Alkistis
Published: November 2019

Sweden has a unique opportunity to identify and follow up women presenting with, or at risk for, perinatal mental health problems and disorders because universal screening programmes are provided by its primary healthcare system. Although they are implemented across almost the entire population, screening programmes are not necessarily leading to effective interventions because the multidisciplinary perinatal mental healthcare teams that provide for the assessment and treatment of moderate to severe disorders are very few in number and must be increased. In particular, efforts to reach immigrant parents must be intensified to achieve equal quality of care for all.
Development of the human placenta
Authors: Turco Margherita Y. , Moffett Ashley
Published: November 2019

The placenta is essential for normal in utero development in mammals. In humans, defective placental formation underpins common pregnancy disorders such as pre-eclampsia and fetal growth restriction. The great variation in placental types across mammals means that animal models have been of limited use in understanding human placental development. However, new tools for studying human placental development, including 3D organoids, stem cell culture systems and single cell RNA sequencing, have brought new insights into this field. Here, we review the morphological, molecular and functional aspects of human placental formation, with a focus on the defining cell of the placenta – the trophoblast.

In addition, the number of employees of territorial executive bodies should reduce, the number of university students and scientists with academic degrees should increase, the innovative activity of organizations should increase, and exports should be stimulated.
Influence of Characteristics of Public-Private Partnership Projects on the Shares of Private and Public Partners in Project Financing
Authors: Trashkin I.
Published: November 2019

The article considers the factors influencing the ratio of private and public investments in public-private partnership projects. Macroeconomic, organizational and financial characteristics of projects potentially affecting the share of the private partner in the project are highlighted. Using correlation and regression analysis, the direction and scale of this impact on the target feature is checked. On the basis of the World Bank database of PPP projects, the impact of the characteristics of PPP projects on the share of the private partner in their financing is estimated. As a result of the empirical study, the following characteristics have a significant impact: GDP deflator, national reserves, country risk premium, income level of the project implementation country, PPP project form, implementation industry, project term, as well as the total amount of investment in the project. On the basis of these characteristics, the classifiers of PPP projects by the share of a private partner are constructed using three algorithms: kNN, SVM, Decision Tree. As a result of testing the classifiers, the maximum accuracy of predictions was achieved by 74% using the Decision Tree algorithm.
Investment in a Smaller World: The Implications of Air Travel for Investors and Firms
Authors: Da Zhi , Gurun Umit G. , Li Bin , Warachka Mitch
Published: November 2019

A large literature reports that proximity influences investment. We extend the measurement of proximity beyond distance and report that air travel reduces local investment bias. This result is confirmed using the initiation of connecting flights through recently opened air hubs because investment at destinations served by these connecting flights increases after, not before, their initiation. Air travel also broadens the investor base of firms and lowers their cost of equity by approximately 1%. Overall, air travel improves the diversification of investor portfolios and lowers the cost of equity for firms.

Authors: Nascimento Milaynne Christina Barros do , De Souza Elio Ferreira
Published: November 2019

Atualmente, o avanço das discussões a respeito dos feminismos vem conquistando mais destaque no Brasil, impulsionando uma série de debates sobre a condição da mulher na sociedade. Nesse panorama, destaca-se também a representação da mulher negra na literatura afrodescendente. O alcance sustentado pela Internet e redes sociais e a organização de diversos grupos mostram que através da indicação de leituras, livros, textos e autoras criam-se canais de expressão e fortalecimento para as discussões sobre a literatura feita por mulheres. Nesse contexto, a escritora nigeriana Chimamanda Ngozi Adichie conquistou lugar de referência ao escrever (e falar) sobre feminismo, identidade, etnia e questões de gênero, temáticas que estão presentes no seu romance Americanah (2014). A protagonista (Ifemelu) ao questionar seu lugar na sociedade cria um blog para poder contar histórias, escrever e refletir sobre sua experiência enquanto mulher negra, nascida na Nigéria e morando nos Estados Unidos. Considerando a leitura e a escrita como articuladores para pensar o lugar das mulheres negras em diáspora, o presente trabalho propõe-se a uma abordagem de leitura sob a perspectiva da afrodescendência e gênero, tendo como corpus da análise o livro Americanah. Investigaremos as diferentes tessituras da representação de identidades afrodescendentes e de gênero, tendo como eixo norteador o processo de criação do blog de Ifemelu. Para tanto, utilizaremos as referências relacionadas aos conceitos de identidade, Du Bois (1999), Hall (2014) e Munanga (1988) e gênero e feminismo em Adichie (2015; 2017) e Ribeiro (2017).

Se presenta una breve sinopsis histórica del término Candombe, su diferenciación con el Candomble, la organización participativa que supone la ejecución de este, su relación actual con la sociedad uruguaya en términos de aceptación en base a los resultados obtenidos en estudios multidisciplinarios realizados por historiadores, musicólogos y antropólogos desde inicios del siglo XX. El articulo destaca el origen del candombe desde una perspectiva interna a la comunidad afro donde se visualiza su rol central de resistencia y conservación de los valores culturales de las distintas naciones africanas llegadas al Rio de la Plata durante el siglo XVIII, regiones donde hoy se localizan Argentina y Uruguay.
Linear Time Ordering of Bins using a Conveyor System
Authors: Makay Géza , Pluhár András
Published: November 2019

A local food wholesaler company is using an automated commissioning system, which brings the bins containing the appropriate product to the commissioning counter, where the worker picks the needed amounts to 12 bins corresponding to the same number of orders. To minimize the number of bins to pick from, they pick for several different spreading tours, so the order of bins containing the picked products coming from the commissioning counter can be considered random in this sense. Recently, the number of bins containing the picked orders increased over the available storage space, and it was necessary to find a new way of storing and ordering the bins to spreading tours. We developed a conveyor system which (after a preprocessing step) can order the bins in linear space and time.
Reconstruction of Rooted Directed Trees
Authors: Bartha Dénes
Published: November 2019

Let T be a rooted directed tree on n vertices, rooted at v. The rooted subtree frequency vector (RSTF-vector) of T with root v, denoted by rstf(T, v) is a vector of length n whose entry at position k is the number of subtrees of T that contain v and have exactly k vertices. In this paper we present an algorithm for reconstructing rooted directed trees from their rooted subtree frequencies (up to isomorphism). We show that there are examples of nonisomorphic pairs of rooted directed trees that are RSTF-equivalent, s.t. they share the same rooted subtree frequency vectors. We have found all such pairs (groups) for small sizes by using exhaustive computer search. We show that infinitely many nonisomorphic RSTF-equivalent pairs of trees exist by constructing infinite families of examples.

Development of a Procedure for the Validation of Statistical Energy Analysis Simulations
Authors: Sipos Dávid , Feszty Dániel
Published: November 2019

This paper describes the development of an NVH measurement procedure that can be used for comparisons to Statistical Energy Analysis (SEA). In SEA, the outputs of the simulation are ensemble averaged quantities for each subsystem, which can be obtained in measurements by averaging some measurement point results. For several reasons, the number of measurement points must be as few as possible, but at the same time, they have to provide a well approximated averaged response of the system. The sufficient number of evaluation points and excitation load cases are determined via Finite Element (FE) simulations. It is shown that in case of a simple, flat plate, 17 randomly chosen evaluation points in at least 3 load cases are enough to properly approximate the SEA results.

Published: November 2019

In the vehicle industry, the noise, vibration and harshness (NVH) characteristics of a car are becoming more and more important. In order to control these, it is necessary to know the sources and contributors to the interior noise level. This paper provide an overview of the state-of-the-art on predicting the NVH characteristics of fully trimmed vehicles in the mid-frequency gap between 400 Hz to 1 kHz. It is shown that for this frequency range, typically a hybrid FE-SEA method is used. This method provides a mixture of the advantages of the deterministic and statistical approaches. The first part of the paper introduces the method, followed by an overview of the different fields of usage in the vehicle industry. At the end of the paper, gaps in the knowledge are identified.

Experimental difficulties often encountered with sludge rheological properties determination and advices to perform reliable measurements
Authors: Thiène Oumar , Dieudé-Fauvel Emilie , Baudez Jean-Christophe
Published: November 2019

Rheological parameters being of great importance for sludge process management, they are increasingly studied. However, experimental procedures may strongly impact their determination. Sample volume, measuring device depth and roughness but also mechanical history, have to be well-controlled to ensure reproducible results. Indeed, even if shear history can be erased with a sufficient preshear for diluted sludge, this paper clearly established that no steady state can be achieved for concentrated sludge. The longer the shear history, the lower the rheological characteristics: Reproducible results are hardly obtained.

More importantly, slippage appeared to occur even with surfaces of moderate roughness and the phenomenon is all the more important that the dry matter is high.

From all these observations, an experimental procedure based on the control of preshear and rest periods has been defined. Advices and precautions to observe are given in order to ensure reproducible and obtain unaltered results.

A Position-Independent Reflection-Only Method for Complex Permittivity and Permeability Determination with One Sample
Authors: Yang Chuang
Published: November 2019

This paper presents a position-independent reflection-only method for determining complex permittivity and permeability of a sample. In this method, both the short and match calibration kits are used to measure the reflection coefficients. Only one sample positioned arbitrarily is measured using a one-port vector network analyzer (VNA), while the complex permittivity and permeability of the sample are determined simultaneously. Experimental results in X-band for the Acrylonitrile Butadiene Styrene plastic (ABS) are included to exhibit the validity of the proposed method. The results show that the complex permittivity and permeability determined by the proposed method have a good agreement with the parameters determined by the well-known Nicolson–Ross–Weir (NRW) method. In addition, a magnetic material is simulated to further validate the proposed method.
Continuous support for rehabilitation using machine learning
Authors: Philipp Patrick , Merkle Nicole , Gand Kai , Gißke Carola
Published: November 2019

Providing a suitable rehabilitation at home after an acute episode or a chronic disease is a major issue as it helps people to live independently and enhance their quality of life. However, as the rehabilitation period usually lasts some months, the continuity of care is often interrupted in the transition from the hospital to the home. Relieving the healthcare system and personalizing the care or even bringing care to the patients’ home to a greater extent is, in consequence, the superior need. This is why we propose to make use of information technology to come to participatory design driven by users needs and the personalisation of the care pathways enabled by technology. To allow this, patient rehabilitation at home needs to be supported by automatic decision-making, as physicians cannot constantly supervise the rehabilitation process. Thus, we need computer-assisted patient rehabilitation, which monitors the fitness of the current patient plan to detect sub-optimality, proposes personalised changes for a patient and eventually generalizes over patients and proposes better initial plans. Therefore, we will explain the use case of patient rehabilitation at home, the basic challenges in this field and machine learning applications that could address these challenges by technical means.
Preparation of spherical aminopropyl-functionalized MCM-41 and its application in removal of Pb(II) ion from aqueous solution

Published: November 2019

Mesoporous silica microspheres were prepared by the polymerization-induced colloid aggregation (PICA) and pseudomorphic synthesis methods. The prepared microspheres have high specific surface area and MCM-41 type structure. In the PICA process, acidic silica sol was utilized as silica source and the effect of molar ration (formaldehyde/urea) was investigated. Moreover, the influences of reaction time and temperature were also studied. The specific surface area of porous and mesoporous silica microspheres were 186.4 m2/g and 900.4 m2/g, respectively. The materials were characterized by SAXS, FTIR, SEM, TEM and nitrogen sorption measurements. The prepared silica microspheres were functionalized by (3-Aminopropyl)triethoxysilane and then used to remove the lead from aqueous solution. The result indicates that the grafted silica microspheres have rapid adsorption capacity and good reproducibility. The adsorption data was fitted well with the Langmuir isotherm model, and the maximum adsorption capacities for MCM-41 silica microspheres were 102.7 mg/g.

An on-fiber extrinsic Fabry–Perot interferometric (EFPI) vibration sensor based on micro-cantilever beam is proposed and experimentally demonstrated. The micro-cantilever beam, with a cantilever length of 80μm and a cantilever thickness of 5μm, is created perpendicular to the fiber axis by using the femtosecond laser micro-machining technique. The on-fiber vibration sensor has same diameter with that of the single mode fiber. An acceleration sensitivity of 11.1 mV/g@300 Hz in the range of 0.5-5g is demonstrated experimentally. This on-fiber and micro-cantilever beam design allows for the sensor to be smaller size and higher temperature resistance.

Published: November 2019

This paper demonstrates a brief review of the research progress of the advanced carbon-based materials for the supercapacitor electrodes. Diverse types of carbon-based electrodes exploited and reported to the literature are summarized and classified into pure carbon electrodes, carbon/metal oxides composite electrodes, carbon/metal oxides/conducting polymers composite electrodes as well as carbon electrodes based on other materials. Pure carbon electrodes are firstly introduced, confirming their merits and shortcomings. To cover the shortage of pure carbon electrodes and further enhances their electrochemical performance, a composite electrode, combined with metal oxides and conducting polymers, is respectively presented. It is worth noticing in this article that combining various materials to form composites has been one main direction to own a positive synergistic effect on the carbon-based electrodes.

Authors: Ladewig Stratton L. , Marcello Robert D.
Published: November 2019

This article seeks to expound upon the first facet of CSNTM’s mission: to capture firsthand digital images of Greek New Testament manuscripts with high resolution digital equipment. By cooperating with likeminded libraries, CSNTM accomplishes the preservation and presentation of cultural heritage artifacts via the utilization of the advances of technology. Details of collaboration, digitization procedures, and preservation and presentation practices are explored, providing a glimpse into this world of artifact digitization. The article then turns to the consideration of ways to improve both digitization and the end user’s experience. While CSNTM engages libraries, archivists, researchers, and students, supportive partners serve to facilitate the work. All are essential, enabling CSNTM to preserve and provide access to timeless treasures.

Published: November 2019

The microstructural characterizations and partitioning of carbon element in the weld heat affected zones of a commercial API 5L X60 line pipe steel were studied by applying a high speed heating and cooling dilatometry technique in the present research work. The hollow cylindrical specimens were quickly heated to 1000°C, soaked for only 5 s followed by continuous cooling to ambient temperature. Besides the construction of CCT diagram of this high strength low alloy steel using the dilatation data, the hardening response, microstructural features and carbon partitioning of weld simulated specimens were investigated. The obtained results showed that the hardening response of samples increased from 142 to 261HV10kg with increasing cooling rates. These hardening variations were attributed to the changes in microstructural features and carbon partitioning that occurred between the microconstituents present in the microstructures of weld simulated samples.
Glauben und Vertrauen im Alten Testament. Eine kognitiv-linguistische Untersuchung
Authors: Ziegert Carsten
Published: November 2019

Der Artikel untersucht und vergleicht die Bedeutung von אמן (Hifil) und בטח. Die Methodik basiert auf der Frame-Semantik, einer Theorie der kognitiven Linguistik. Diese rechnet mit prototypischen Situationen, die bei Sprachbenutzern durch die Verwendung von Wörtern evoziert werden. Aus den biblischen Texten werden ein Frame für האמין und ein Frame für בטח rekonstruiert. האמין setzt einen Inhalt voraus, den ein personales Gegenüber äußert und den die »glaubende« Person für wahr hält. בטח dagegen setzt eine (potenzielle) Gefahr voraus, deren Abwendung die »vertrauende« Person erwartet.
Copper hydroselenite nitrates (A+NO3)n[Cu(HSeO3)2] (A=Rb+, Cs+and Tl+,n=1, 2) related to Ruddlesden – Popper phases
Authors: Markovski Mishel R. , Charkin Dmitri O. , Siidra Oleg I. , Nekrasova Diana O.
Published: November 2019

Three new layered copper hydrogen selenite nitrates, (ANO3)[Cu(HSeO3)2] (A = Cs, and Tl), and (RbNO3)2[Cu(HSeO3)2] have been prepared via isothermal evaporation of concentrated nitric acid solutions. The Tl and Cs compounds adopt a motif related to previously known (NH4Cl)[Cu(HSeO3)2]; the structure of the Rb compound represents a new structure type. The structures of (ANO3)[Cu(HSeO3)2] (A = Cs, Tl), (RbNO3)2[Cu(HSeO3)2], and (NH4NO3)3[Cu(HSeO3)2] form a unique homological series distantly related to Ruddlesden – Popper series of layered perovskites.
Bildung durch die Praxis der „Gewöhnung“? Von der Kraft der Gestaltung menschlichen Lebens in der Orthodoxie
Authors: Vletsis Athanasios
Published: November 2019

Die aristotelische Fundierung der Ethik (auch) in der „Gewöhnung“, was somit den Charakter einer in der Polis gelebten und erprobten Praxis gegenüber einer rein verstandesmäßigen Aneignung von Tugenden hervorhebt, gibt den Anlass, die Orthodoxe Theologie diesbezüglich zu hinterfragen. Dabei ist es nötig, ein gutes Stück Schöpfungstheologie und Anthropologie zu rekonstruieren und zugleich mit Hilfe der orthodoxen Patristik (hier v. a. von Maximos Bekenner) die Möglichkeiten der Gestaltung einer kontingenten, fragilen menschlichen Existenz auch durch die Erziehung (Paideia) des Leidens hindurch aufzuzeigen. Die Orthodoxe Tradition trägt in diesem Sinn aristotelische Züge, wenn der Praxis v. a. in der Gemeinschaft vor der Theoria Priorität gewährt wird, was ihr Bildungspotenzial v. a. zu erweitern und vielfältiger zu gestalten erlaubt.
Learning with Icons in Religious Education and Youth Ministry
Authors: Vrame Anton C.
Published: November 2019

Ikone gehören zu den prägenden Kennzeichen der Orthodoxen Kirche. Über Jahrhunderte hinweg haben sie bei Betrachtenden Resonanzen ausgelöst. Ikone besitzen auch pädagogisches Potenzial: sie können informieren, formen und transformieren. In diesem Beitrag werden Handlungsstrategien vorgestellt, wie die Auseinandersetzung mit Ikonen für religiöse Lernprozesse fruchtbar gemacht werden kann. Die didaktischen Überlegungen werden am Beispiel eines US-amerikanischen Unterrichtsbuches veranschaulicht und konkretisiert.
Whitefellas (From the book Walk Back Over)
Authors: Leane Jeanine
Published: November 2019

Walk Back Over alludes to a bridge across the Murrumbidgee River where I grew up but, more symbolically, mirrors the need to revisit our past. Much was made of the 2000 Reconciliation Walk across Sydney Harbour Bridge—many settler Australians walked across this and other bridges, and I am not cynical about that—but there are many other spans in Australia that must be walked: not just once, walked back over.
Pedestrian Pedagogy: The Walking Library for Women Walking
Authors: Heddon Dee , Myers Misha
Published: November 2019

The Walking Library for Women Walking (2016-18) is an edition of the ongoing creative research project, The Walking Library. Co-created and launched in 2012 by Dee Heddon and Misha Myers, The Walking Library explores the multiple relationships between walking, literature, and environment (see Heddon & Myers 2014, 2017, in press).

For each edition of The Walking Library, we invite donations and suggestions of books to accompany what we propose is a pedestrian pedagogy: a learning that takes place on foot and on the move in the company of others (present and virtual), sharing and creating knowledge side-by-side, step-by-step and without hierarchy. Pedestrian pedagogy facilitates meaning-making as emergent and re-orientating (Osberg et al., 2008). In this pedestrian pedagogy learning is improvisatory and relational, engendered through the collaborative and collective body of walkers moving through space and time, side by side, in the company of each other and a diverse collection of books.
Postcards from the Underground
Authors: Neimanis Astrida , Phillips Perdita
Published: November 2019

This article draws lessons from a walkshop organised by the authors to Lithgow, NSW, where participants walked through a park dedicated to former coal-based infrastructures to arrive at the Lithgow mining museum. The aim of the walkshop was to better understand the tensions around groundwater and extraction in Australia. This article focuses on two key elements of the walkshop: (1) First, they interrogate an attempt to engage bodily with an elemental phenomenon—groundwater—that is for the most part inaccessible to human experience. The authors thus draw on the practice of posthuman phenomenology (Neimanis) to explain how bodily attunement to our own wateriness, alongside the “proxy stories” of arts and sciences expertise, can aid in bringing groundwater into lived experience. (2) Second, they ask how walkshopping—as a coming together—can nonetheless hold onto the ambivalences, tensions, and glitches that are part of sharing space in the face of fraught issues such as mining. Here, the authors turn to Lauren Berlant’s recent writing on the commons. They suggest that their walkshop was what Berlant would call ‘training’ in living with the awkward and complicit relations of being in common.
