A DINÂMICADO PASSADO E DO FUTURO
Authors: PINHEIRO Ulysses
Published: May 2020

No Livro II, capítulo 6, §§39-45 de seu Ensaio sobre o entendimento humano, Locke compara as ideias de espécies artificiais (como relógios, navios, sapatos) às ideias de modos mistos (como a traição), opondo ambas às ideias de espécies naturais; segundo ele, essas últimas, ao visarem substâncias extra mentais, seriam mais obscuras e confusas do que as duas primeiras, as quais, justamente por serem ideias de realidades forjadas pelo arbítrio e pelo intelecto humanos, esgotam sua realidade em convenções e práticas inteiramente evidentes para o autor de sua fabricação. Esse trecho ilumina a passagem do capítulo 27, na qual Locke afirma que “pessoa” é um “termo forense” – i.e., uma realidade que é construída por necessidades ligadas a nossa vida prática. Um dos principais comentadores de Locke no século XVIII, Edmund Law, cujo texto A Defense of Mr. Locke’s Opinion concerning Personal Identity fez parte de várias edições da obra de Locke a partir de 1777, propunha uma interpretação similar a essa; segundo Law, “A personalidade [é] apenas uma criação da sociedade, [...] necessária para o benefício mútuo [dos homens]; i.e., um mero termo forense”; “Trata-se de uma distinção artificial, ainda assim fundada na natureza, mas não na natureza integral do homem”.2 É essa interpretação ciceroniana de pessoa como sendo uma qualidade, uma personagem, de seres inteligentes que desempenha um papel fundamental na teoria lockiana da moral (ao menos tal como ela é formulada no Ensaio): só através dela é possível mostrar que um agente capaz de ser imputado moral e juridicamente por suas ações tem acesso a suas próprias intenções e decisões de modo claro e distinto. Além de considerar as ações humanas como modos mistos capazes de integrar uma ciência dedutiva da moralidade, Locke tem de pressupor o acesso das pessoas a sua essência própria para que a moral possa ter fundamentos certos, pois só através desse acesso as intenções das ações podem ser determinadas. Se isso for correto, a teoria de Locke poderia ser caracterizada como envolvendo, ao mesmo tempo, elementos convencionais e tipos naturais com relação à determinação da natureza das pessoas. Tipos naturais, porque o conceito de pessoa, embora pessoas não sejam seres substanciais, envolve necessariamente atos de pensamento de substâncias (as quais, quer sejam elas espirituais ou materiais, são seres vivos pertencentes ao mundo natural), apreendidos reflexivamente. Elementos convencionais, porque há um interesse em nós mesmos que explica por que queremos nos ver como pessoas, interesse que só pode ser realizado por meio de uma atitude com relação a nosso próprio “eu” mediada por convenções (na medida mesma em que faz parte da natureza humana estabelecer convenções e leis que, ao regular, constituem sua vida prática).
ALIX COHEN: KANT’S LECTURES ON ANTHROPOLOGY. ACRITICALGUIDE. CAMBRIDGE UNIVERSITY PRESS, 2014, 270 PP. ISBN: 978-1-107-02491-5.
Authors: GASPERONI Lidia
Published: May 2020

Il volume edito da Alix Cohen mira a far emergere l’importanza della pubblicazione delle Vorlesungen über die Anthropologie di Kant nel volume XXV dell’Akademie-Ausgabe, edito nel 1997 da Reinhard Brandt e Werner Stark e la traduzione inglese delle Lezioni nella Cambridge Edition nel 2006. La rilevanza storica e filosofica di queste lezioni vuole essere così messa in luce e svincolata da quel carattere accessorio rispetto agli scritti critici e all’Antropologia stessa, che la hanno caratterizzata per molto – e forse troppo – tempo. Il destino di queste riflessioni antropologiche nell’ultimo decennio è già iniziato a cambiare e si è aperta una nuova fase di ricerca sul ruolo da esse svolto nell’intero sistema kantiano. Il volume curato da Cohen ha sicuramente il merito di continuare questo dibattito e arricchirlo di nuovi contributi che vado qui a riassumere in breve.
KANT, RÉFLEXIONS SURLA PHILOSOPHIE MORALE ET BAUMGARTEN. PRINCIPES DE LA PHILOSOPHIE PRATIQUE PREMIÈRE, INTRODUCTION ET TRADUCTION PAR LUC LANGLOIS, PARIS: VRIN, 2014, 419 PP.
Authors: LEQUAN Mai
Published: May 2020

Le présent ouvrage propose une traduction annotée et précédée d’une longue Présentation (33 pages) de deux textes complémentaires, qui marquèrent, bien qu’à divers titres, la philosophie pratico-morale allemande du milieu du XVIIIe siècle - les Réflexions sur la philosophie morale de Kant et les Principes de la philosophie pratique première de Baumgarten - par Luc Langlois, en collaboration avec Mathieu Robitaille (pour la traduction des Réflexions) et Emilie Jade-Poliquin (pour la traduction des Principes). Les Réflexions de Kant ne constituent pas un ouvrage à proprement parler, mais un ensemble de notes et remarques rédigées par Kant, en lien avec son enseignement en philosophie morale qui s’étala sur plus de 30 ans, souvent inscrites dans les marges (ou sur des feuillets séparés) du principal manuel que Kant utilisait comme fil directeur de ses cours de philosophie morale à l’Université de Königsberg, à savoir les Initia philosophiae practicae primae d’Alexander Gottlieb Baumgarten (Halle, édition de 1760). Ces deux textes sont donc inséparables dans la mesure où le premier, reflet direct des enseignements de morale de Kant, s’inspire largement du second, dont il propose de larges commentaires. La présentation concomitante de ces deux textes permet à la fois d’apprécier l’influence des Principes de Baumgarten sur Kant et la manière dont Kant intègre, en se les réappropriant et en les infléchissant, à sa propre philosophie morale des thèmes empruntés à Baumgarten.
Substance, change and matter in the Analogies of Experience of Kant’s Critique of Pure Reason.
Authors: Rosales Jacinto Rivera de
Published: May 2020

This article explains in ten points the concepts of substance, change and matter that appear in the transcendental Analytics of Kant’s Critique of Pure Reason as categories and schemes, as well as how they function in the Analogies of Experience. It aims to demonstrate how the category in general, and that of substance in particular, are, in their transcendental ideality, a strategy of the subject to order and objectify the phenomenal world. It establishes that change is also necessary a priori, that both change (accident) and persistence (substance), as well as all appearances, are finite and limited. This would lead to the affirmation that only matter, transcendental matter, is entirely persistent; however, transcendental matter is not a sensible object and therefore those sensible objects that relatively persist in time-space are the only empirical reality of the substance. Finally, matter is made up of forces, and given that there is nothing simple in matter, it can be inferred that empirical substance is nothing other than a field of forces.

Fé.
Authors: Silva Claudia Fidalgo da
Published: May 2020

Kant investigates the concept of faith [Glaube] several times in his philosophy and under various perspectives. In one of them, the author investigates this concept, contrasting it with the definitions of opinion and knowledge (cf., for example, KrV, A 822/ B 850; KU, §91, AA 05: 454; Log, AA 09: 66). Another perspective on which Kant investigates the concept of faith is pointing to the distinction between pure religious faith, as the one that can establish a true Church, and ecclesiastical faith, as a historical faith, not having “the most important mark of its [Church] truth, namely the legitimate claim to universality” (RGV, AA 06: 109).Many questions have arisen in the contemporary debate on these topics, such as the various and divergent positions on Kant’s claim “I had (…) to remove knowledge, in order to make room for belief” (B XXX), the relationship between different types of faith and pure religious faith, the proximity between the Kantian concept of pure rational faith and Christianity or questions related to faith in organization of human being, in order to create an ethical community.

ANÁLISE FUNCIONAL DE CONECTIVOS EM PORTUGUÊS: DA ABORDAGEM CLÁSSICA À CONSTRUCIONAL
Authors: Oliveira Mariangela Rios
Published: May 2020

Neste artigo, tratamos da análise dos conectivos da língua portuguesa à luz dos pressupostos do Funcionalismo. Na primeira seção, voltamo-nos para o tratamento dos conectivos como classe gramatical do português, com foco em suas propriedades funcionais. Na segunda seção, partimos de uma abordagem clássica dessa classe, baseada nos pressupostos funcionalistas das décadas finais do século XX, a partir dos fundamentos da gramaticalização e da investigação de itens específicos, como se encontra em Givón (1979) e Heine et al (1991), entre outros. Na sequência, chegamos ao tratamento dos conectivos na vertente da Linguística Funcional Centrada no Uso, tendência recente de nossa pesquisa, que integra o tratamento construcional da gramática ao Funcionalismo, nos termos de Traugott e Trousdale (2013) e Hilpert (2014), entre outros. Nessa vertente atual, os conectivos são investigados em perspectiva construcional, de modo mais amplo e holístico, levando em conta as propriedades do contexto em que são usados e os níveis de vinculação de forma e sentido de suas subpartes, conforme a taxonomia proposta por Diewald (2002, 2006).

A MODALIDADE FACULTATIVA NO PORTUGUÊS DO CARIRI: UMA ABORDAGEM DISCURSIVO-FUNCIONAL
Authors: Lima Liliane Viana , Prata Nadja Paulino Pessoa
Published: May 2020

A modalidade facultativa está ligada às noções de condições físicas/circunstanciais, habilidades e capacidades (HENGEVELD; MACKENZIE, 2008). Com base nos pressupostos da Gramática Discursivo-Funcional (HENGEVELD; MACKENZIE, 2008), objetivamos descrever e analisar as possíveis relações existentes entre os tipos de modalidade facultativa e seus meios de expressão no português falado no Cariri, tendo em vista os elementos do Componente Gramatical, mais especificamente os relativos aos Níveis Representacional e Morfossintático. Para isso, utilizamos uma amostra do corpus do PROFALA, referentes à fala do cearense,composto por 60 entrevistas do tipo DID. Após a análise quali-quantitativa, chegamos aos seguintes resultados: (i) o alvo de avaliação mais recorrente foi o ‘orientado-para-oparticipante’, em 97,6% dos casos; (ii) a ‘modalidade facultativa orientada-para-o participante” relaciona-se ao subtipo ‘adquirida’; (iii) os meios de expressão mais usado para manifestação da ‘modalidade facultativa orientada-para-o-participante’ foram os verbos ‘poder’, ‘saber’ e conseguir’. Por fim, com a discussão dos resultados finais encontrados, esperamos contribuir com a descrição e análise da modalidade facultativa no português do Cariri.

ASPECTOS SINTÁTICOS DA EVIDENCIALIDADE NA LÍNGUA PORTUGUESA
Authors: Carioca Cláudia Ramos
Published: May 2020

Este artigo objetiva identificar e descrever as marcas linguísticas evidenciais manifestas pelos aspectos sintáticos que permitem a distinção entre o enunciador e outra fonte da informação veiculada, analisando por que meios linguísticos o autor do texto sinaliza a fonte daquilo que enuncia. Ao identificar e interpretar as marcas evidenciais na construção do discurso acadêmico, a pesquisa busca contribuir para a explicitação dos efeitos de sentido relacionados à veiculação das informações de forma estratégica, já que essas marcas são utilizadas com propósitos diversificados, tais como o recurso ao chamado “argumento de autoridade”, a busca por atenuação da responsabilidade em relação ao que é dito etc. Nesse intuito, a proposta assumida nesta pesquisa é que, segundo a Gramática Discursivo-Funcional (2008), os aspectos sintáticos são regidos pela pragmática e pela semântica, ou seja, a explicitação das marcas evidencias foi feita considerando-se a ênfase na interação verbal e na intencionalidade (escolha dos efeitos de sentido) do produtor textual.

Very rare Image for Rheumatoid tricuspid valve changes
Authors: Hadi abdulsalam Abo Aljadayel  , Saied Saeid Hosseini
Published: May 2020

Rheumatic tricuspid valve disease occurs in association with rheumatic involvement of the mitral aortic valves combined. The third world still have a significant prevalence of rheumatic tricuspid valvular disease. The preponderance of cases is in young women. Rheumatic tricuspid disease usually results in a regurgitant valve with variable amounts of stenosis, Borders of the stenotic tricuspid orifice are usually fibrous and thickened, although peripheral portions of the leaflets remain thin. The hallmark of organic tricuspid stenosis is commissural fusion. All commissures are usually equally fused, but occasionally fusion is limited to the anteroseptal commissure. Chordal thickening and fusion are usually mild, and calcification is usually absent.

Regular use of entropy for studying dissimilar geographical phenomena
Authors: Tuček Pavel , Pászto Vít , Voženílek Vít
Published: May 2020

The concept of entropy connected with GIS is relatively new. Its mathematical background was defined after World War II by Claude E. Shannon, well-known mathematician, electronic engineer and founder of information theory. Information theory deals with entropy as measure of information which every single message has. And thus entropy quantifies the amount of information in a message. The paper is based on entropy applications in cartography and demonstrates its usage as a measure of information in GIS. The authors provide an algorithm for setting number of intervals in thematic maps with using entropy calculations. Finally, the obtained knowledge is applied to sample datasets for creating climatic maps within GIS environment.

The article deals with changes in ethnic structure in 13 political units of the North and the South Caucasus resulting from societal processes going on after the last 1989 Soviet census and illustrated by the outcome of censuses held in 1999–2005. The study deals with changes in population share of titular groups, Russians and other ethnic groups, with changing urbanization level and general regional population growth. It also makes an assessment of substantial changes in the ethnic structure in selected territories in connection with political and economical factors influencing the post-1989 development of the region and its ethno-territorial entities.
Extremal quasiconformality vs bounded rational approximation
Authors: Krushkal Samuel
Published: May 2020

We show that, on most of the hyperbolic simply connected domains, the weighty bounded rational approximation in a natural sup norm is possible only for a very sparse set of holomorphic functions (in contrast to the integral approximation). The obstructions are caused by the features of extremal quasiconformality.

The purpose of the paper is to determine the most typical and frequently used orthograms to pay attention to, when teaching Russian as a foreign language in a primary school. Our practical experience of teaching and our observation of the process of learning Russian as a foreign language allows us to state and suggest that schools lack systematic and focused teaching of Russian orthography. Pupils make a lot of mistakes because they do not understand the reason why such mistakes occur, they lack orthographic vigilance, i.e., the ability and skills to determine an orthographically “dangerous place”.
Most teachers do not include practices and spelling skills of forming orthographic literacy into the context of their class activities and do not know practices of working on orthograms of different types and origin. It is considered that pupils learn Russian orthography through listening comprehension and through books and, thus, remember and memorize the spelling of different words well enough.
It is believed that the pupil’s first step in the creation of a system of exercises to form orthographic literacy is the development of a classification of orthograms that are topical and frequent in teaching Russian as a foreign language in a primary school (forms 6–9).
Similar research was conducted several decades ago, therefore, it is now necessary to develop and determine the methodology as well as technology for conducting an experiment and revealing the currently most typical orthographic and spelling mistakes.
The classification of orthograms has been made with account of a comparative analysis of phonetic, orthographic and graphic systems of the Russian and Latvian languages. For the Latvian audience, it is expedient to single out phonetic and non-phonetic orthograms. Phonetic orthograms are those caused by underdeveloped phonemic awareness, interference of Latvian pronunciation and incorrect articulation of Russian sounds (seven types have been singled out). Non-phonetic orthograms (morphologic and traditional) are true orthograms and their spelling causes difficulties for both Latvian and Russian pupils.
To determine the frequency and quality of mistakes in the Russian language, we have performed a diagnostic assessment.
The data of our practical research can be used in forecasting mistakes of pupils who study Russian as a foreign language, creating a system of monitoring skills and abilities in writing, developing tests and exercises to contribute to the improvement of orthographic literacy of pupils.
Causality between Economic Growth and Health Expenditure: A time series analysis from 1996 till 2017 in Albania
Authors: Xhindi Teuta , Kripa Ermela , Shestani Kevin
Published: May 2020

-Evidence shows that human capital is a leading driver and one of the most important factors affecting economic development. Economic growth models emphasize the effect that human capital has on the growth and prosperity of a country. The indicators used to measure human capital vary. In this article we will use total health expenditure as a measure for human capital. A healthier population will obviously lead to increased productivity and consequently a higher income for the individual. By increasing public health investments, the workforce will potentially be healthier and consequently human productivity will increase. One of the most important lessons to be learned from the coronavirus pandemic is the importance of investments in health care services, human resources and technical infrastructure for the economy. The aim of this article is to study the relationship between Health Care Expenditure (HCE) per capita and Gross Domestic Product GDP per capita in Albania. The data (in $) is taken from the World Health Organization website, for the time period 1996-2017. The methods used are the ARDL Bounds testing approach for co-integration and the Granger causality test. The main results are: the variables per capita GDP and per capita HCE are not cointegrated. The ARDL(1,1) model estimation points out the positive relationship between the two variables. Also, our study confirms the existence of joint causality between per capita GDP and per capita HCE.

Asymptotic Properties of the Hazard Function and the Mean Residual Life Function
Authors: Škanata Dejan
Published: May 2020

The memoryless or non-aging property of systems is of special relevance in reliability theory, which implies that the hazard function is constant in time, and the corresponding mean residual life function takes a reciprocal value. The only known continuous distribution with that property is the exponential distribution. However, many other distributions exist whose asymptotic behavior of underlying hazard functions approaches a constant, while the mean residual life function approaches a reciprocally constant value. Here we provide an analysis which enables us to study a class of distributions that asymptotically approach the memoryless property, and which include gamma, Erlangian, exponential resilience, exponential geometric, hyper exponential, logistic exponential and the inverse Gaussian distribution.

INVESTOR ATTENTION AND STOCK RETURNS UNDER NEGATIVE SHOCKS: AN EMPIRICAL ANALYSIS BASED ON “DRAGON AND TIGER” LIST IN CHINA
Authors: Zhai Xiao-ying , Hou Ying-ying , Li Yuan-shun
Published: May 2020

Using the “Dragon and Tiger” list, we construct a clean indicator that directly measures investor attention, empirically test the effect of investor attention on stock return under negative shocks and whether the effect is affected by the bull or bear market, the industry, firm size, age and state ownership, institutional shareholder holding percentage. The results show that i) an increase in investor attention negatively predicts stock returns when cumulative daily return of a stock listed on “Dragon and Tiger” list on listing day is negative; ii) Investor attention is negatively correlated with stock returns when the stock entered in “Dragon and Tiger” list experienced current cumulative monthly return is negative; iii) Investor attention is negatively correlated with stock returns when monthly cumulative net purchase amount of top 10 institution to the stock listed in “Dragon and Tiger” list is negative; iv) Investor attention is negatively correlated with stock returns when the stock listed in “Dragon and Tiger” list, the ratio of monthly cumulative trading amount of the top 10 institutional traders to total trading amount of the secondary market is in the bottom 30 percentile. These findings not only contribute to the academic research about the relationship between investor attention and stock return, but also provide some guidance to the financial regulatory agencies as to the capital market stability.

Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia
Authors: Pearce Logan A. , Kraus Adam L. , Dupuy Trent J. , Mann Andrew W. , Newton Elisabeth R. , Tofflemire Benjamin M. , Vanderburg Andrew
Published: May 2020

The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitude and (mis)alignment of angular momentum vectors among stars, disks, and planets probes the complex dynamical processes guiding their formation and evolution. The accuracy of the Gaia catalog can be exploited to enable comparison of binary orbits with known planet or disk inclinations without costly long-term astrometric campaigns. We show that Gaia astrometry can place meaningful limits on orbital elements in cases with reliable astrometry, and discuss metrics for assessing the reliability of Gaia DR2 solutions for orbit fitting. We demonstrate our method by determining orbital elements for three systems (DS Tuc AB, GK/GI Tau, and Kepler-25/KOI-1803) using Gaia astrometry alone. We show that DS Tuc AB’s orbit is nearly aligned with the orbit of DS Tuc Ab, GK/GI Tau’s orbit might be misaligned with their respective protoplanetary disks, and the Kepler-25/KOI-1803 orbit is not aligned with either component’s transiting planetary system. We also demonstrate cases where Gaia astrometry alone fails to provide useful constraints on orbital elements. To enable broader application of this technique, we introduce the python tool lofti_gaiaDR2 to allow users to easily determine orbital element posteriors.

While the floors of deep lunar craters are largely shielded from solar radiation and thus provide an ideal thermal environment for water-ice accumulation, meteoroids on highly inclined orbits can easily access permanently shadowed regions and alter the surface properties via hypervelocity impacts. Here we consider the detailed topography of the lunar poles and a dynamical model of meteoroids to quantify the meteoroid mass fluxes, energy deposition, and impact ejecta mass production rates. Our analysis of regions within 5° from the two lunar poles shows that the variations of the meteoroid mass flux, energy flux, and ejecta production rate are within 50% of their median values. We find that the lunar poles are easily accessible by meteoroid impacts, including the permanently shadowed regions. We find a positive correlation between the surface slope and the meteoroid ejecta production rate, a finding that suggests that a higher impact gardening rate on steep crater walls can facilitate mass wasting.
Thermal Formation of Ammonium Carbamate on the Surface of Laboratory Analogs of Carbonaceous Grains in Protostellar Envelopes and Planet-forming Disks
Authors: Potapov Alexey , Jäger Cornelia , Henning Thomas
Published: May 2020

The catalytic role of dust grain surfaces in the thermal reaction CO2 + 2NH3 → NH4
+NH2COO− was recently demonstrated by our group. The rate coefficients for the reaction at 80 K on the surface of nanometer-sized carbon and silicate grains were measured to be up to three times higher compared to the reaction rate coefficients measured on KBr. In this study, the reaction was performed on carbon grains and on KBr in the extended temperature range of 50–80 K and with the addition of water ice. The reaction activation energy was found to be about three times lower on grains compared to the corresponding ice layer on KBr. Thus, the catalytic role of the dust grain surface in the studied reaction can be related to a reduction of the reaction barrier. Addition of water to NH3:CO2 ice on grains slowed the reaction down. At the H2O:CO2 ratio of 5:1, the reaction was not detected on the experimental timescale. This result calls into question the thermal formation of ammonium carbamate in dense molecular clouds and outer regions of protostellar and protoplanetary environments with dominating water ice mantle chemistry. However, it can still happen in inner regions of protostellar and protoplanetary environments in crystalline ices.

Published: May 2020

We have obtained a contiguous set of long-slit spectra of a shock wave in the Cygnus Loop to investigate its structure, which is far from the morphology predicted by 1D models. Proper motions from Hubble Space Telescope images combined with the known distance to the Cygnus Loop provide an accurate shock speed. Earlier analyses of shock spectra estimated the shock speed, postshock density, temperature, and elemental abundances. In this paper we determine several more shock parameters: a more accurate shock speed, ram pressure, density, compression ratio, dust destruction efficiency, magnetic field strength, and vorticity in the cooling region. From the derived shock properties we estimate the emissivities of synchrotron emission in the radio and pion decay emission in the gamma-rays. Both are consistent with the observations if we assume simple adiabatic compression of ambient cosmic-rays as in the van der Laan mechanism. We also find that, although the morphology is far from that predicted by 1D models and the line ratios vary dramatically from point to point, the average spectrum is matched reasonably well by 1D shock models with the shock speed derived from the measured proper motion. A subsequent paper will analyze the development of turbulence in the cooling zone behind the shock.
Onset of Magnetic Explosion in Solar Coronal Jets in Quiet Regions on the Central Disk
Authors: Panesar Navdeep K. , Moore Ronald L. , Sterling Alphonse C.
Published: May 2020

We examine the initiation of 10 coronal jet eruptions in quiet regions on the central disk, thereby avoiding near-limb spicule-forest obscuration of the slow-rise onset of the minifilament eruption. From the Solar Dynamics Observatory/Atmospheric Imaging Assembly 171 Å 12 s cadence movie of each eruption, we (1) find and compare the start times of the minifilament's slow rise, the jet-base bright point, the jet-base-interior brightening, and the jet spire, and (2) measure the minifilament's speed at the start and end of its slow rise. From (a) these data, (b) prior observations showing that each eruption was triggered by magnetic flux cancelation under the minifilament, and (c) the breakout-reconnection current sheet observed in one eruption, we confirm that quiet-region jet-making minifilament eruptions are miniature versions of CME-making filament eruptions, and surmise that in most quiet-region jets: (1) the eruption starts before runaway reconnection starts, (2) runaway reconnection does not start until the slow-rise speed is at least ∼1 km s−1, and (3) at and before eruption onset, there is no current sheet of appreciable extent. We therefore expect that (i) many CME-making filament eruptions are triggered by flux cancelation under the filament, (ii) emerging bipoles seldom, if ever, directly drive jet production because the emergence is seldom, if ever, fast enough, and (iii) at a separatrix or quasi-separatrix in any astrophysical setting of a magnetic field in low-beta plasma, a current sheet of appreciable extent can be built only dynamically by a magnetohydrodynamic convulsion of the field, not by quasi-static gradual converging of the field.
European Union Monitoring Mission in Georgia (2008-2019): contribution to stability or part of a problem?
Authors: Smejkalová Tereza
Published: May 2020

The EU Monitoring Mission (EUMM) is the only international monitoring presence operating in the region with the consent of the Russian Federation. However, almost 11 years in the area did not bring the desired result. The Russian Federation has strengthened its position in Abkhazia and South Ossetia with more than 20,000 troops on the ground, hardened the border and even prevented the schools from teaching children in Georgian. Following the assessment on the basis of three criteria (stabilization, normalization and confidence building), the EUMM attempts to increase the confidence building, to mediate among the actors in order to achieve a normal and a stable environment. But on the other hand, EUMM enables also the Russian federation to officialise its presence and its troops in the breakaway regions.

Hungry scale worms: Phylogenetics of Peinaleopolynoe (Polynoidae, Annelida), with four new species
Authors: Hatch Avery S. , Liew Haebin , Hourdez Stéphane , Rouse Greg W.
Published: May 2020

Polynoidae Kinberg, 1856 has five branchiate genera: Branchipolynoe Pettibone, 1984, Branchinotogluma Pettibone, 1985, Branchiplicatus Pettibone, 1985, Peinaleopolynoe Desbruyères & Laubier, 1988, and Thermopolynoe Miura, 1994, all native to deep-sea, chemosynthetic-based habitats. Of these, Peinaleopolynoe has two accepted species; Peinaleopolynoe sillardi Desbruyères & Laubier, 1988 (Atlantic Ocean) and Peinaleopolynoe santacatalina Pettibone, 1993 (East Pacific Ocean). The goal of this study was to assess the phylogenetic position of Peinaleopolynoe, utilizing DNA sequences from a broad sampling of deep-sea polynoids. Representatives from all five branchiate genera were included, several species of which were sampled from near the type localities; Branchinotogluma sandersi Pettibone, 1985 from the Galápagos Rift (E/V “Nautilus”); Peinaleopolynoe sillardi from organic remains in the Atlantic Ocean; Peinaleopolynoe santacatalina from a whalefall off southern California (R/V “Western Flyer”) and Thermopolynoe branchiata Miura, 1994 from Lau Back-Arc Basin in the western Pacific (R/V “Melville”). Phylogenetic analyses were conducted using mitochondrial (COI, 16S rRNA, and CytB) and nuclear (18S rRNA, 28S rRNA, and H3) genes. The analyses revealed four new Peinaleopolynoe species from the Pacific Ocean that are formally described here: Peinaleopolynoe orphanae Hatch & Rouse, sp. nov., type locality Pescadero Basin in the Gulf of California, Mexico (R/V “Western Flyer”); Peinaleopolynoe elvisi Hatch & Rouse, sp. nov. and Peinaleopolynoe goffrediae Hatch & Rouse, sp. nov., both with a type locality in Monterey Canyon off California (R/V “Western Flyer”) and Peinaleopolynoe mineoi Hatch & Rouse, sp. nov. from Costa Rica methane seeps (R/V “Falkor”). In addition to DNA sequence data, the monophyly of Peinaleopolynoe is supported by the presence of ventral papillae on segments 12–15. The results also demonstrated the paraphyly of Branchinotogluma and Lepidonotopodium Pettibone, 1983 and taxonomic revision of these genera is required. We apply the subfamily name Lepidonotopodinae Pettibone 1983, for the clade comprised of Branchipolynoe, Branchinotogluma, Bathykurila, Branchiplicatus, Lepidonotopodium, Levensteiniella Pettibone, 1985, Thermopolynoe, and Peinaleopolynoe.

Assessment of pretreatments on drying kinetics and quality characteristics of thin-layer dried red pepper
Authors: İNCEDAYI Bige
Published: May 2020

In this study, the effect of pretreatments (hot water blanching, microwave blanching, and ohmic heating) on the drying kinetics and quality characteristics of red pepper, dried at 60 and 70 °C, was investigated. The drying times varied between 205–290 min, depending on the pretreatment and temperature applied. The drying rate also changed based on the pretreatment and the falling rate period was observed. Four mathematical models were fitted to experimental data and the logarithmic model was found to be the best for all of the samples. Effective moisture diffusivity values obtained from Fick’s second law of diffusion ranged from 6.11 × 10–10 to 9.31 × 10–10 m2 s–1. The total phenolic contents, antioxidant capacities, and red pigment amounts of the dried peppers varied between 6.95 and 9.45 mg GAE g–1dry matter (DM), 2610.43 and 4463.96 mmol AEAC 100 g–1DM, and 184 and 443mg 100 g–1DM, respectively. Rehydration ability of pretreated samples was similar to or slightly lower than that of the untreated samples. As a result, it can be suggested that ohmic heating before drying at a temperature of 70 °C could be a promising alternative pretreatment to decrease drying time and produce high-quality dried red pepper.

Customized Ablation Area PTK as a Technique for Salzmann's Degeneration and Other Focal Stromal Pathologies
Authors: Chacra Lily M. , Arba-Mosquera Samuel , Awwad Shady T.
Published: May 2020

PURPOSE:

To introduce a customized ablation area photo-therapeutic keratectomy (PTK) technique that uses a preoperatively generated laser ablation profile to accurately match and ablate the area of the pathology.

METHODS:

A case of mid-peripheral Salzmann's nodular degeneration causing recurrent epithelial erosion is described. The white-to-white distance, on a slit-lamp image of the patient's eye, was measured by a Placido and dual-Scheimpflug analyzer and used as a scale on a Java-based image processing program to extrapolate the focal corneal pathology's vertical and horizontal dimensions on the corneal plane. The lesion's depth was measured by corneal optical coherence tomography (OCT). Customized ablation area transepithelial PTK, tailored to the exact dimensions of the pathology was then performed in one pass, regionally ablating the area of the pathology only.

RESULTS:

Complete epithelial healing was observed by the next day with unaltered visual acuity of 20/20. Corneal OCT performed at 1 and 3 months postoperatively showed near-complete resolution of the lesion. The patient was followed up for a total of 6 months with no reported symptoms of corneal erosions.

CONCLUSIONS:

The application of a customized laser ablation area in the treatment of Salzmann's nodular degeneration and other focal stromal pathologies avoids unnecessary epithelial and stromal ablation. This contributes to faster visual recovery and less refractive impact, especially for peripheral lesions.

A family of potential wells for a wave equation
Authors: Liu Yang , Li Wenke
Published: May 2020

In this paper, a family of potential wells are introduced by means of the modified depths of the potential wells. These potential wells are employed to study the initial-boundary value problem for a wave equation. The expression of the depths of the potential wells is derived. Global existence and finite time blow-up of weak solutions with the subcritical initial energy and the critical initial energy are obtained, respectively. Moreover, some numerical simulations of the depths of the potential wells are carried out.
