Monitoring Robust Estimates for Compositional Data
Authors: Todorov Valentin
Published: February 2021

In a number of recent articles Riani, Cerioli, Atkinson and others advocate the technique of monitoring robust estimates computed over a range of key parameter values. Through this approach the diagnostic tools of choice can be tuned in such a way that highly robust estimators which are as efficient as possible are obtained. This approach is applicable to various robust multivariate estimates like S- and MM-estimates, MVE and MCD as well as to the Forward Search in whichmonitoring is part of the robust method. Key tool for detection of multivariate outliers and for monitoring of robust estimates is the Mahalanobis distances and statistics related to these distances. However, the results obtained with thistool in case of compositional data might be unrealistic since compositional data contain relative rather than absolute information and need to be transformed to the usual Euclidean geometry before the standard statistical tools can be applied. Various data transformations of compositional data have been introduced in the literature and theoretical results on the equivalence of the additive, the centered, and the isometric logratio transformation in the context of outlier identification exist. To illustrate the problem of monitoring compositional data and to demonstrate the usefulness of monitoring in this case we start with a simple example and then analyze a real life data set presenting the technologicalstructure of manufactured exports. The analysis is conducted with the R package fsdaR, which makes the analytical and graphical tools provided in the MATLAB FSDA library available for R users.

Authors: Kravchenko О.
Published: February 2021

The article highlights the social and political conditions under which the proletarian educational organizations of the 1920s functioned in the context of nationality issue, namely the study of political frameworks determining the status of the Ukrainian language and culture in Ukraine. The nationality issue became crucial in Proletkult activities – a proletarian cultural, educational and literary organization in the structure of People's Commissariat, the aim of which was a broad and comprehensive development of the proletarian culture created by the working class. Unlike Russia, Proletkult's organizations in Ukraine were not significantly spread and ceased to exist due to the fact that the national language and culture were not taken into account and the contact with the peasants and indigenous people of nonproletarian origin was limited.

Authors: Michule Evita , Rozenfelde Mārīte , Ogrina Regina
Published: February 2021

Children nowadays have insufficient vocabulary, difficulties in expressing their opinion and expressing themselves, difficulties in asking questions and answering them. Therefore, it can be concluded that it is important to improve child's speech and vocabulary, which includes all of the aforementioned elements. Even after eliminating the pronunciation disorders of the sounds s-z and sh-zh, it is necessary to develop the active and passive vocabulary, to ensure that as many words as possible are in the active vocabulary. It is important to improve the grammatical structure of the language, so that children can form longer simple extended sentences instead of sentences consisting of 2-3 words. It is necessary to work on improving the conversational language, so that children, when answering questions, can substantiate their thoughts, attitudes, are able to perceive the essence of the content, preserve it and express themselves in the end. The paper provides information about a set of speech therapy games, developed and approbated by E. Michule, for the enrichment of the vocabulary of 5-6 year old children after the elimination of pronunciation disorders of the sounds s-z and sh-zh, as well as the results obtained in the approbation.

A scheme of the installation for alloying from the gas phase is described. The possibility of uniform alloying with sulfur and phosphorus of samples and material in the form of plates or foils with a thickness of 0.2 mm or thinner at a concentration ranging between 0.001 and 0.08) at. % is shown. Diffusion annealing is carried out after heating and pumping out in a high vacuum and without contamination, in a quartz volume containing sulfur or phosphorus vapors at a temperature of 1100 to 1200 °C. By choosing the ratio of the masses of the alloyed material and the corresponding filling of sulfur or phosphorus, it is possible to predict in advance the resulting concentration of impurities with a sufficient time of annealing. The impurity concentration is uniform in volume within ten percent. Modeling and control annealings with the measurement of the residual resistivity of the control samples allows you to evaluate the results obtained.

La redención del Derecho administrativo en la post-pandemia
Authors: Hernández G. José Ignacio
Published: February 2021

La COVID-19 está demostrando la necesidad del Estado Administrativo, para asegurar la satisfacción de necesidades diversas y complejas, desde contener la enfermedad en medio de la regulación de emergencia, hasta brindar alivio económico a sectores vulnerables. Al mismo tiempo, la pandemia está mostrando la fragilidad del Estado Administrativo, debido a la brecha de capacidad estatal que deriva en áreas de limitada estatalidad, esto es, tareas que las Administraciones Públicas no pueden atender. En consecuencia, la post-pandemia requerirá del Derecho Administrativo orientado a reforzar la capacidad estatal y asegurar la protección del bien común, con base en los estándares de la buena administración. Desde el Derecho Administrativo fallido, es necesario evolucionar hacia un Derecho Administrativo efectivo.

Direct Solar Absorption Nanoparticle Doped Membranes for a Hybrid Membrane Distillation and Photovoltaic Cell
Authors: Espejo Sanchez Alejandro
Published: February 2021

The growing demand for clean water supplies is driving the need for an innovative approach of water desalination. Developing a method for treating water with high salinities is possible with membrane distillation (MD). Additionally, MD is very attractive for pairing with solar energy due to the low temperature requirements. The integration of a membrane distillation system with a photovoltaic (PV) system will result in the co-production of electricity and clean water, thereby improving the economics of MD. Such a hybrid system will directly absorb thermal energy in the membrane for desalination while taking advantage of the spectrally selective nature of PV to generate electricity. At the top of the system is a PV cell that will filter the visible light wavelengths and transmit the remaining ultraviolet and infrared to a membrane doped with absorbing nanoparticles located at the core of the system. This configuration integrates the system and provides an avenue for increasing the membrane performance by mitigating the temperature polarization effect, which is the gradual decrease of temperature at the thermal boundary layers of the membrane due to the large amount of heat consumed during the phase transition process. A custom multi-step phase inversion process fabricates Polyvinylidene Fluoride (PVDF) membranes through a Diffusion Induced Phase Separation (DIPS) technique. The process allows for the addition and controlled distribution of nanoparticles at different loadings across the membrane structure. The membranes fabricated during this study exhibited a microporous, sponge-like, and hydrophobic nature during the morphological analysis. Scanning Electron Microscopy (SEM) images and contact angle measurements above 100° prove the suitability for MD applications. The membranes doped with a 0.8wt% load of carbon coated copper nanoparticles increased the solar absorptance of the membrane by 80% during the optical analysis. A custom lab-scale direct contact membrane distillation (DCMD) setup characterizes the membranes fabricated off-sun and on-sun. The doped membrane exhibited a 15-32% increase in desalination performance when exposed to solar irradiance while simultaneously producing 0.36W of electrical power. The overall project led to the increased use of renewable energy for desalination while improving the ability to use MD for desalination purposes.

Authors:   Capital Normal University, Beijing, China, Ma Xiaoyang , Xu Min , Dong Yao , Sun Zhong
Published: February 2021

With the continuous and rapid growth of online courses, online learners’ engagement recognition has become a novel research topic in the field of computer vision and pattern recognition. While a few attempts to automatic engagement recognition has been studied in the literature, learning a robust engagement measure is still a challenging task. To address it, we propose a new automatic engagement recognition method based on Neural Turing Machine in this paper. In particular, we firstly extract student’s eye gaze features, facial action unit features, head pose features, and body pose features respectively, then combine these multi modal features into the final feature of our recognition task. Moreover, we propose the engagement recognition framework based on the idea of Neural Turing Machine to learn the weight of each short video feature. In consequence, the feature fused by different weights will be applied to identify the students’ engagement in learning online courses. Empirically, we show improved performance over state of the art methods to automatic engagement recognition on DAiSEE dataset.
Firm-Embedded Productivity and Cross-Country Income Differences
Authors: Alviarez Vanessa , Cravino Javier , Ramondo Natalia
Published: February 2021

We measure the contribution of firm-embedded productivity to cross-country income differences. By firm-embedded productivity we refer to the components of productivity that differ across firms and that can be transferred internationally, such as blueprints, management practices, and intangible capital. Our approach relies on micro-level data on the cross-border operations of multinational enterprises (MNEs). We compare the market shares of the exact same MNE in different countries and document that they are about four times larger in developing than in high-income coun-tries. This finding indicates that MNEs face less competition in less-developed coun-tries, suggesting that firm-embedded productivity in those countries is scarce. We propose and implement a new measure of firm-embedded productivity based on this observation. We find a strong positive correlation between our measure and output per worker across countries. In our sample, differences in firm-embedded productivity account for roughly a third of the cross-country variance in output per worker.

Published: February 2021

By the last millennium of the twentieth century, phraseology was established as an independent branch of linguistics, and now it is being developed in several directions. One of them is the theory of idioethnic phraseology. This doctrine considers the asymmetry in phraseology and the semantic description of the resulting phraseological units (PhU), the concept of phraseological paradigm (PhP), the “cap” as a phraseological category, and its relationship to phraseological derivation. This paper focuses on phraseological units and the difficulties in teaching students during the corona crisis. We use the World Bank’s data on Kazakhstan (summer 2020), building on the narrative that “the COVID-19 pandemic has a negative impact on the development of human capital not only in Kazakhstan, but all over the world. Uneven access to quality education, especially during the quarantine period, can negatively affect the development of human beings.” Because of said challenges, many educational establishments transferred the education system to distance learning. Teaching languages, especially when teaching phraseology, requires a lot of strength, a good grasp of modern technology, and innovative approaches. The aim of our research is to identify (1) the semantic field of the somatic idioms based on relevant historical and literary texts and (2) viable ways of teaching students during the corona crisis

The objective of this paper is to explore the adequacy of French as a foreign language (FFL), with specific context to teaching and learning of the beginners' course for the International Network for Education in Emergencies (INEE) standards. Specifically, in terms of the impact of coronavirus pandemic on teaching foreign languages. The paper utilized qualitative methodology with the two mediums of direct observation and the open questionnaire. According to the study results, adaptive changes were seen in the curriculum, and these were in accordance with the INEE standards for education in emergencies. For example, revision in the contents, planning and methodologies. More specifically, while the Blackboard platform saw an increase in the new learning materials and written communicative activities in the forum; there was a clear reduction in the oral skills and language practice. Also, in comparison the use of traditional methodology was seen to be higher than the communicative method.

Published: February 2021

This paper is devoted to the study of general issues of teaching English terminology in the electric power industry during the Coronavirus. The outbreak of the pandemic posed a serious challenge to education systems around the world. For the first time ever, traditional face-to-face training turned out to be impossible. Governments’ decision to make distance education compulsory on all levels in the context of the coronavirus pandemic was unprecedented but needed. The development of the electric power industry affects the state of various industries and the daily life of people around the world. The search for alternative forms of education during the time of the crisis, therefore, became urgent. The aim of our research paper was to create a substantiated, experimentally proven methodology for teaching students terminological vocabulary of the professional language of the electric power industry during Coronavirus. In addition, we identified strategies for mastering professional terminological vocabulary pertaining to reading specialized texts as well as to oral communication in professionally significant communication situations focused on the electric power industry. To achieve this goal, the following tasks needed to be completed: (1) to study linguistic, psychological, psycholinguistic, methodological literature on the problems of teaching terminological vocabulary; (2) to determine the features of the functioning of the lexical skills of operating with professional terms; (3) to determine the lexical features of the terminological vocabulary of the sublanguage “the electric power industry”; (4) to develop based on this typology a technology for teaching students the skills of using terminological vocabulary in the process of oral and written communication; (5) to check the effectiveness of the proposed methodology in the process of experiential learning.

Authors: MUSLU ERDEM Vuslat , SAYAN Halil Erkan , KORFALİ Sefika Gulsen
Published: February 2021

Objectives: Surgeries can trigger stress responses including metabolic and hormonal changes. It is important to suppress stress response during surgery. We compared the effects of isoflurane and sevoflurane on surgical stress in intracranial tumor surgery.
Methods: Thirty ASA physical status I, II, III patients, scheduled for elective craniotomies, were enrolled in this prospective, randomized study. Anesthesia was induced with sodium thiopental fentanyl and vecuronium bromide and maintained with a 50% oxygen-air mixture along with isoflurane or sevoflurane. Venous blood was sampled to measure cortisol, ACTH and prolactin levels 24 hours before surgery, 1 min before anesthesia induction, during tumor removal, 1 min after extubation, at 3, 6, 12, 24, 48 hours.
Results: There was no statistically significant difference between two groups regarding demographic characteristics of patients. In group I, ACTH levels were significantly higher 1 min after extubation, at 3 and 6 hours. In Group S, significant increases were observed during tumor removal, 1 min after extubation, at 3 and 6 hours. Cortisol levels were significantly higher in both group after tumor removal, 1 min after extubation, at 3, 6, 12 and 24 hours. Prolactin levels were significantly higher in Group I during tumor removal, after extubation, at 3 and 6 hours. In group S, significant increase in prolactin level was observed only during tumor removal and 1 min after extubation. There were no significant differences in ACTH, cortisol and prolactin values between the two groups.
Conclusions: Using isoflurane or sevoflurane for anesthesia during intracranial tumor surgery are not superior to each other regarding hemodynamic and hormonal stress response.
Wastelands as an opportunity for managing Naples’ sustainable transition
Authors: Berruti Gilda , Palestino Maria Federica
Published: February 2021

Circular economy offers new visions of how diversely urban spaces could be inhabited and managed. While the generation and management of waste is being treated through innovative practices, disused industrial, rural, and infrastructural areas are resistant to becoming included in a closed-loop cycle. They, in fact, establish wastelands that need to be completely re-imagined as a precondition for the transition. The fact of shifting the definition of a ’neglected area’ into a ‘wasteland’, in line with the metaphor of urban metabolism, could be of tactical importance for generating alternative policies and practices. In exploring how the transition impacts Naples’ urban region, the paper argues that turning wastelands into resources has the double potential of rehabilitating spaces and challenging the governance model in use, overcoming barriers in multiple sectors.

Russian fairy tales in the USA: Alexander Alexeieff’s graphic interpretation and Roman Jacobson’s scientific comprehension
Authors: Zvonareva Lola U. , Zvonarev Oleg V.
Published: February 2021

We analyze the graphic commentaries of Alexander Alexeieff, the illustrator and the first wave emigrant, made for The Russian Fairy tales published in the USA in 1946. We believe A. Alexeieff to have been the second to illustrate The Russian Fairy tales in the USA as Ivan Bilibin, the eminent Russian painter and book illustrator had preceded him. A. Alekseev brought his vision of artistic images to the illustration of The Russian Fairy tales, combining ancient Slavonic motives with Christian symbolism. We assume the publication also to be unique as Roman Jakobson, the well-known philologist an ancient Slavonic and Russian folklore explorer wrote the foreword to the book being cited in Russian for the first time. Having briefly considered R. Jakobson’s life and creative work, we presume it to be quite logical Jacobson to have been baptized according to the Russian Orthodox tradition, as well as to have backed up the theory of Eurasianism. From this point of view, the analyzed edition of The Russian Fairy tales is holistic in content, harmoniously combining the traditional values of the cultural heritage of the Russian world and the work of outstanding figures that developed and propagated its values and enduring significance through their works.
Molecular identification of the genus Molicola larvae from swordfish (Xiphias gladius) captured in Sri Lanka by ribosomal subunit gene sequencing
Authors: De Silva DPN , Perera JLCS , Fernando HSD , Ranatunga RRMKP , De Silva BGDNK
Published: February 2021

Swordfish (Xiphias gladius) is a migratory fish commercially exploited due to high export value. Presence of parasites in fish lead to economic losses in the export market and public health issues. This study was conducted to identify the parasite larvae inhabiting swordfish and to determine its phylogenetic origin using ribosomal subunit gene sequence. Parasite samples were extracted from swordfish muscles and five larvae belong to Molicola genus, confirmed by scolex morphology, were used for genomic DNA extraction. Polymerase chain reaction (PCR) was performed to amplify 18S and 28S ribosomal RNA (rRNA) subunit genes followed by Sanger sequencing. DNA sequences were edited by BioEdit software and assembled by CLC genomics version 8.0. Consensus sequences were aligned with NCBI blast to determine the species status. Isolated larval sequences were best aligned with genus Molicola followed by genus Gymnorhyncha.  Out of the two published Molicola rRNA gene sequences, 99% identity was observed with Molicola sp. HP5 isolate from Indonesia. Due to lack of sequence data on other Molicola species (except M. thyristes) for comparison, our sequences were published as Molicola sp. Sri Lankan isolates. This is the first record of Molicola sp. in swordfish from Sri Lanka and the results will enhance the knowledge on the distribution of Molicola species while contributing to expand the genetic information on rRNA coding sequences.

Disposal Pit Nangka merupakan area yang terindikasi mengalami erosi karena pengaruh kecuraman lereng, area timbunan dan tingginya intensitas hujan. Laju erosi menyebabkan terkikisnya tanah secara terus-menerus dan jika tanah tidak dapat menampung air maka akan menimbulkan longsor. Oleh karena itu diperlukan adanya perkuatan saluran.Pada penelitian ini, metode perhitungan curah hujan rencana menggunakan 4 (empat) distribusi dan dilakukan uji chi kuadrat untuk memilih distribusi yang cocok. Curah hujan rencana yang terpilih adalah sebesar 85,07 mm. Untuk penentuan catchment area menggunakan software didapat total catchment area sebesar 0,1438 km2, pada area 1 sebesar 0,0618 km2,area 2 sebesar 0,0446 km2 dan area 3 sebesar 0,0374 km2. Perhitungan debit limpasan menggunakan metode rasional pada Area 1 sebesar 2,65 m3/s, Area 2 sebesar            2,10 m3/s, dan Area 3 sebesar 1,89 m3/s. Terdapat dua dimensi saluran terbuka yaitu saluran tanpa ban dan saluran menggunakan ban. Dimana penempatan dimensi ban dipengaruhi oleh bilangan Froude sedangkan untuk mengetahui laju erosi menggunakan metode USLE.Hasil perhitungan menunjukan bahwa pada segmen-segmen dengan slope yang besar memiliki kecepatan aliran super kritis, sehingga segmen tersebut memerlukan perkuatan. Pendugaan erosi berdasarkan metode USLE pada tahun 2018 adalah sebesar 32.358,02 m3. Hal ini menyebabkan butuhnya perkuatan saluran dengan tyre drop structure agar kecepatan aliran dapat diminimalkan. Kata Kunci : catchment area, USLE, drop structure, laju erosi

Introduction. Focal alopecia in the parietal area is one of the types of hair loss that can be found in dermatological practice. Trichoscopy is a non-invasive and easily accessible diagnostic method widely used in scalp disorders.Aim. The aim of this study was to assess the usefulness of trichoscopy in the non-invasive diagnosis of focal hair loss in adult women.Material and Methods. The study included 40 adult women. The study group consisted of 30 patients including 10 patients with alopecia areata (AA), 10 patients with discoid lupus erythematosus (DLE) and 10 with classical form of lichen planopilaris (LPP). The control group consisted of 10 healthy volunteers. Four groups of structures observed in trichoscopic examination were evaluated: hair follicle openings, hair shafts, vessels, perifollicular and interfollicular skin surface. Results. Among patients with AA the most frequently observed trichoscopic structures were: yellow dots in 100% (10/10), broken hairs in 90% (9/10), hairs resembling exclamation marks in 90% (9/10). DLE patients most often presented white / white-pink structureless areas and prominent, interfollicular scaling in 100% (10/10) and 90% (9/10) of cases, respectively. On the other hand, in the group of patients with LPP, the most frequent findings were: fine perifollicular scaling in 100% (10/10) and linear, slightly branched vessels arranged concentrically around the follicular openings - both features observed also in 100% (10/10) of cases.Conclusion. Trichoscopy as a non-invasive diagnostic method may be helpful in differentiating non-scarring and scarring alopecia in the parietal area in women. Moreover, there are some trichoscopic features typical for AA, DLE and LPP, which allow for differentiation and facilitate the diagnosis of these entities.

Introduction. The severity of facial wrinkles is related to many factors, such as: endogenic skin aging (innate mechanisms), the influence of external factors (photoaging) and lifestyle factors such as smoking or body weight.Aim. The aim of the study is to determine the relationship between BMI and the occurrence of various types of facial wrinkles.Material and Methods. 50 people participated in the study, including 9 men and 41 women. The criteria for participation in the study were: age over 18, no visible facial hair, no makeup. Each volunteer had their weight and height examined — BMI was determined and 6 extraoral photographs were taken. The severity of wrinkles in 9 facial areas was analyzed, and their severity was assessed on the basis of a photographic scale by three independent researchers. The obtained data were analyzed statistically. The adopted limit of statistical significance was p <0.05.Results. There was a statistically significant correlation between BMI and the severity of mouth angle wrinkles.Conclusions. The relationship between BMI and the severity of the wrinkles of the mouth angle may be determined by the weight of the subcutaneous tissue around the mouth angle, however, it requires more detailed research.

Published: February 2021

Use of porous titanium (Ti) and Ti alloys in orthopedic implants or in light structures requires processing routes that could generate an as-much-as possible control in the pores amount, shape, size and connectivity. In this work, a colloidal approach to the processing of Ti porous structures by the inside foaming of a porogen into a gelled high solid content aqueous suspension of Ti powders, is presented. The prepared slurries contained different amounts of Methyl Cellulose (MC) as gelling agent (8, 10 and 12 g/L) and ammonium bicarbonate (BA) as porogen (15, 20, 25 wt. %). The gel-casted samples were heated at mild temperatures ranging (60, 70 and 80 °C) to promote the gelation and produce, at the same time, the porosity by the thermal decomposition of the ammonium bicarbonate. Different structures are obtained depending on the combination of the study variables

This paper presents the results of the investigation of composite sinters W-TiB2 which were used as an electrode in the process of electro-spark deposition (ESD) and the examination of the deposited layers. The scope of the study includes detailed characteristics of powder mixtures, composite sinters made using the spark plasma sintering method (SPS) and layers deposited in the electro-spark process. The ESD process, using the W+30 vol.% TiB2 electrode, was carried out using an automated device. The substrates were made of copper and aluminium. The topography analysis of the surfaces of the composite layer and the evaluation of their wear resistance properties are also presented. The analysis of the results of research showed the possibility to obtain, using the SPS method, composite materials of good quality, which can be used as electrodes in the ESD process. The obtained layers had increased wear resistance in relation to the substrate material.

Electron Beam Melting (EBM) is one of the most promising techniques within Metal Additive Manufacturing (AM) strategies, which presently is for the manufacture of high execution segments for the aviation and clinical businesses, generally. Among the modern applications imagined for the eventual fate of EBM, the creation of high carbon prepares for the tooling business is of extraordinary interest. In this study, martensitic highly alloyed (Cr-Mo-V) cold-work tool steel was produced by EBM. A suitable heat treatment was proposed in order to obtain an optimal microstructure, which was studied by means of optical and scanning-electron microscopy. The performance of the material was evaluated based on the hardness achieved and the abrasive wear resistance of the material processed through EBM when compared with that of the conventionally produced state.
