Poetic metre as a function of language: linguistic grounds for metrical variation in Estonian runosongs
Authors: Sarv Mari 
Published: March 2020

The article focuses on the relationship of language and metre in case of oral poetry, more exactly, to what extent and through which processes the changes in language have induced the changes in metre in case of Estonian runosong, a branch of common Finnic poetic-musical tradition. The Estonian language has gone through a series of notable phonological changes during approximately last 500 to 700 years that have systematically shortened the word forms; the extent of these changes varies across dialects. At the same time the language of runosongs has partly resisted these changes, and partly adopted; the archaic and new word forms are in concurrent use, and vary geographically. The metre of Estonian runosongs appears to be a transitional form from quantitative runosong metre (Kalevala metre) to the accentual runosong metre (both of them syllabic metres). The current study shows that the transition depends directly on the average syllabic length of the words in runosongs (the longer the words, the more quantitative the metre, and vice versa), which in turn is induced by the shortening of words in dialectal language. The closer look at the points of tensions between the metre and language, i.e. the geographical distribution of the morphological forms that are critical for building the verses in quantitative metre and have been systematically retained in runosongs (but shortened in language) shows that in two metrically innovative areas runosongs have given up preserving the archaic word forms, while in big central area between a linguistically and metrically conservative centre in the North-East of Estonia and two innovation centres in Western and Southeastern Estonia the archaic and newer word forms are used concurrently. The slight difference between the metre of western and southeastern runosongs follows the prosodic patterns of dialectal language.
The side topic of the article discusses the questions of the evolution of runosong in the light of newer theories of emergence of Finnic languages (in the first millennium BC) and poetic system of runosongs, but apparently the metrical variation of runosong is entirely explicable by the impact of much later language changes (approximately 500 to 700 years ago) and seems not to be able to answer the questions related to the emergence of the poetic tradition.

Published: March 2020

We present a practical wide-field optical design for a 60 m aperture submillimeter telescope, which is currently under conceptual design study in China. The telescope is specified to operate over a wavelength range of 0.65–3 mm and provide a wide field of view (FOV) of 1° in diameter. We designed an F/6 Ritchey Chrétien (RC) system with a quasi-planar tertiary corrector, which cancels all spherical, coma, and astigmatism aberrations. It also achieves a good balance among the mirror sizes, central obscuration, and focal-plane curvature. The problems of focal surface curvature and nontelecentricity are treated in the subfield instrumental design, which employs a simple silicon wedge prism to obtain flat and telecentric focal planes for each subfield instrument module. Our studies show that by such a design, more than

detector pixels can be efficiently and uniformly fed at the shortest wavelength band with Strehl ratios above 0.85 across the entire 1° FOV. Several practical issues related to the telescope optics are also discussed.
Constelações de uma práxis pedagógica: o sensível, a linguagem, as infâncias e a memória (presenças de Walter Benjamin) na formação docente
Authors: Miklos Dilson 
Published: March 2020

Linguagem, arte, infância e memória são alguns dos conceitos que o ensaio apresenta a partir do olhar de Walter Benjamin que nos acompanha na escrita a fim de extrair enunciados de um contexto voltado à formação de professores. Nesse percurso são apresentados dois conceitos que emergem da pesquisa docente, a saber: práxis poética e narrativimagem. O campo do sensível é o lócus onde aflora esse conjunto de saberes que se comunica poeticamente e que objetiva refletir sobre o currículo e práticas pedagógicas outras. Ainda, há o esforço, na companhia do filósofo berlinense, de compreender o processo da formação a partir de uma perspectiva menos totalizante e definitiva.

Strongly s-dense injective hull and Banaschewski’s theorems for acts
Authors: Barzegar Hasan 
Published: March 2020

Abstract
For a class 𝓜 of monomorphisms of a category, mathematicians usually use different types of essentiality. Essentiality is an important notion closely related to injectivity. Banaschewski defines and gives sufficient conditions on a category 𝓐 and a subclass 𝓜 of its monomorphisms under which 𝓜-injectivity well-behaves with respect to the notions such as 𝓜-absolute retract and 𝓜-essentialness.
In this paper, 𝓐 is taken to be the category of acts over a semigroup S and 𝓜
sd
to be the class of strongly s-dense monomorphisms. We study essentiality with respect to strongly s-dense monomorphisms of acts. Depending on a class 𝓜 of morphisms of a category 𝓐, In some literatures, three different types of essentialness are considered. Each has its own benefits in regards with the behavior of 𝓜-injectivity. We will show that these three different definitions of essentiality with respect to the class of strongly s-dense monomorphisms are equivalent. Also, the existence and the explicit description of a strongly s-dense injective hull for any given act which is equivalent to the maximal such essential extension and minimal strongly s-dense injective extension with respect to strongly s-dense monomorphism is investigated. At last we conclude that strongly s-dense injectivity well behaves in the category Act-S.
Returning functions with closed graph are continuous
Authors: Banakh Taras , Filipczak Małgorzata , Wódka Julia 
Published: March 2020

Abstract
A function f : X → ℝ defined on a topological space X is called returning if for any point x ∈ X there exists a positive real number Mx
such that for every path-connected subset Cx
⊂ X containing the point x and any y ∈ Cx
∖ {x} there exists a point z ∈ Cx
∖ {x, y} such that |f(z)| ≤ max{Mx
, |f(y)|}. A topological space X is called path-inductive if a subset U ⊂ X is open if and only if for any path γ : [0, 1] → X the preimage γ
–1(U) is open in [0, 1]. The class of path-inductive spaces includes all first-countable locally path-connected spaces and all sequential locally contractible spaces. We prove that a function f : X → ℝ defined on a path-inductive space X is continuous if and only if it is returning and has closed graph. This implies that a (weakly) Świątkowski function f : ℝ → ℝ is continuous if and only if it has closed graph, which answers a problem of Maliszewski, inscribed to Lviv Scottish Book.
Filippov solutions of vector Dirichlet problems
Authors: Machů Hana 
Published: March 2020

Abstract
If in the right-hand sides of given differential equations occur discontinuities in the state variables, then the natural notion of a solution is the one in the sense of Filippov. In our paper, we will consider this type of solutions for vector Dirichlet problems. The obtained theorems deal with the existence and localization of Filippov solutions, under effective growth restrictions. Two illustrative examples are supplied.
Hamiltonicity of a class of toroidal graphs
Authors: Maity Dipendu , Upadhyay Ashish Kumar 
Published: March 2020

Abstract
If the face-cycles at all the vertices in a map are of same type then the map is said to be a semi-equivelar map. There are eleven types of semi-equivelar maps on the torus. In 1972 Altshuler has presented a study of Hamiltonian cycles in semi-equivelar maps of three types {36}, {44} and {63} on the torus. In this article we study Hamiltonicity of semi-equivelar maps of the other eight types {33, 42}, {32, 41, 31, 41}, {31, 61, 31, 61}, {34, 61}, {41, 82}, {31, 122}, {41, 61, 121} and {31, 41, 61, 41} on the torus. This gives a partial solution to the well known Conjecture that every 4-connected graph on the torus has a Hamiltonian cycle.
Sirt4 Modulates Oxidative Metabolism and Sensitivity to Rapamycin Through Species-Dependent Phenotypes in Drosophila mtDNA Haplotypes
Authors: Sejour Richard , Sanguino Roger A , Mikolajczak Monika , Ahmadi Walishah , Villa-Cuesta Eugenia 
Published: March 2020

Abstract
The endosymbiotic theory proposes that eukaryotes evolved from the symbiotic relationship between anaerobic (host) and aerobic prokaryotes. Through iterative genetic transfers, the mitochondrial and nuclear genomes coevolved, establishing the mitochondria as the hub of oxidative metabolism. To study this coevolution, we disrupt mitochondrial-nuclear epistatic interactions by using strains that have mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) from evolutionarily divergent species. We undertake a multifaceted approach generating introgressed Drosophila strains containing D. simulans mtDNA and D. melanogaster nDNA with Sirtuin 4 (Sirt4)-knockouts. Sirt4 is a nuclear-encoded enzyme that functions, exclusively within the mitochondria, as a master regulator of oxidative metabolism. We exposed flies to the drug rapamycin in order to eliminate TOR signaling, thereby compromising the cytoplasmic crosstalk between the mitochondria and nucleus. Our results indicate that D. simulans and D. melanogaster mtDNA haplotypes display opposite Sirt4-mediated phenotypes in the regulation of whole-fly oxygen consumption. Moreover, our data reflect that the deletion of Sirt4 rescued the metabolic response to rapamycin among the introgressed strains. We propose that Sirt4 is a suitable candidate for studying the properties of mitochondrial-nuclear epistasis in modulating mitochondrial metabolism.

Published: March 2020

The second fundamental source of law for Moslems is the Hadith. The Hadith can be used to explain Quranic texts. However, Hadith still needs to be translated according to each national language to easily understand its meaning [1]. In Indonesia Hadith more usually refers to a special class of relevance to more particular religious concern [1]. Base on that, this research will Classify the translation Hadith Text into three classes: Obligation, Prohibition, and Information. From previous research, the Back Propagation Neural Network (BPNN) showed good performance in classifying hadith text. Therefore, BPNN was used to solve the problem of hadith text classification in this study. However, the dataset has a huge number of varied bag-of-words, which are features that will be used in the classification process. Hence, Information Gain (IG) was utilized to select influential features, and as the sequential process before the classification process. To measure the performance of this system, the Macro F1-Score was used. The F1-Score enables one to observe exactness from precision and completeness from recall. The Macro F1-score is also needed for the performance evaluation of more than two classes. Based on the experiment conducted, the system was able to classify hadith text using BPNN, IG, and without stemming, yielding the highest F1-score of 84.63%. However, the system performance that included the stemming process yielded an F1-score of 80.92%. This shows that the stemming process could decrease classification performance. This decreasing performance is due to some influential words merging with more noninfluential words.
Descripción del embarazo ectópico en el hospital San Juan de Dios de Cali, Colombia, entre el 2005 y el 2006
Authors: Cuero-Vidal Olga Lucía 
Published: March 2020

Objetivos: calcular la razón de incidencia y describir las características sociodemográficas, clínicas y el tratamiento de las mujeres con embarazo ectópico (EE), que fueron atendidas en el Hospital San Juan de Dios de Cali (HSJD), entre el 1 de abril de 2005 y el 31 marzo de 2006.Diseño del estudio: es un estudio descriptivo prospectivo, con información de la base de datos del departamento de estadística del HSJD y los datos de una encuesta estructurada para las mujeres con EE.Resultados: se atendieron 3722 nacidos vivos en este período y hubo 78 mujeres con EE. La incidencia fue del 2,1%, el promedio y la mediana de edad fue 26 años, el 65,4% no tenían ningún régimen de seguridad social, el 79% eran remitidas de otras instituciones. El dolor abdominal fue la principal causa de consulta (42,3%); el 53,8% no planificaban, entre las que planificaban el 29% lo hacían con oclusión tubárica bilateral, hubo un 7,7% con EE previo y éste era su segundo embarazo y su segundo ectópico. De las 78 mujeres con EE todas fueron llevadas a laparotomía y el promedio de hemoperitoneo fue 544cc y la mediana 500cc, 59% eran ectópicos derechos y el 88,5% estaban rotos, en el 96,7% de los casos el tratamiento fue salpingectomía total.Conclusión: la incidencia de embarazo ectópico fue del 2,1%; considerada como alta con respecto a la reportada en la literatura, predomina el diagnóstico tardío de la entidad en esta comunidad, lo cual no permitió tratamientos conservadores.
Miomatosis uterina e infertilidad: ¿qué evidencias tenemos como causa y como tratamiento?
Authors: Pérez Luis Ernesto , Diaz Ivonne , Ospina Luis 
Published: March 2020

Objetivos: revisar las evidencias actuales que determinen el impacto de la miomatosis uterina en la infertilidad, así como la seguridad y la eficacia de las diferentes formas de tratamiento quirúrgico conservador.Metodología: revisión sistemática cualitativa, consultando las fuentes de datos de Cochrane (Menstrual Disorders and subfertility), Medline (PubMed -MeSH), y de OVID (EBM); desde 1995 a 2008.Resultados: muchos estudios observacionales han sugerido que los miomas causantes de infertilidad son todos los submucosos, los intramurales mayores de 5 cm que alteren la cavidad uterina y también los subserosos cuya cantidad y tamaño distorsionen la fisiología reproductiva. Pero no hay estudios aleatorizados controlados (RCTs) que soporten estas afirmaciones. En la actualidad, las miomectomías constituyen la mejor forma de tratamiento para pacientes infértiles. Por histeroscopia se deben resecar miomas submucosos menores de 5 cm, tipos 0 y I; por laparoscopia miomas intramurales o subserosos menores de 10 cm y no más de 5 miomas; finalmente, por laparotomía es posible resecar todo tipo de miomas, independientemente de su localización, tamaño y número. No hay RCTs que comparen la histeroscopia con otras técnicas de miomectomías; pero sí los hay mostrando que las indicaciones para laparotomía y laparoscopia son igualmente efectivas en resultados reproductivos.Conclusión: hay evidencias limitadas soportando la miomatosis como causante de infertilidad, y las miomectomías por histeroscopia respecto a otros tratamientos conservadores. Sin embargo, hay RCTs que muestran iguales resultados reproductivos al realizar miomatomías intramurales o subserosas por laparoscopia y por laparotomía en pacientes seleccionadas.

HANNA AND “HER” CINEMA. ON THE BOOK KINO HANNY SCHYGULLI, ED. A. GWÓŹDŹ, WROCŁAW 2015, 394 PP.The paper is a review of Kino Hanny Schygulli a volume published in the series “Niemcy — Media — Kultura” “Germany — Media — Culture”, edited by Andrzej Gwóźdź. Contributors of the publication represent various disciplines and present their own unique view. As a consequence, the main aim of the volume — which is to show a phenomenon of Schygulla’s art of acting in the broadest perspective — is fulfilled. The actress is presented as a creative entity, an exceptional co-author of films in which she performed. The author of the review claims that although the contributors analyze an interesting and still undescribed issue, the book does not meet the reader’s expectations, provoked by the editor’s initial assumptions expressed in the preface. The biggest deficiency of the volume seems to be the lack of solid theoretical background in describing the connection between the author and the actor developed in theatre and film studies.
