A síndrome da casa tomada
Authors: Luft Eduardo
Published: April 2019

To overcome the paradoxical situation in which the modern subject finds itself, on conceptualizing nature in such a way that its very presence in nature becomes inconceivable, modernity supplied at least four alternatives: a) the first is to defend dualism (Descartes, Kant); b) the second option is to support a monism of nature (Spinoza, Hobbes); c) the third alternative is to defend a monism of subjectivity (Fichte); d) the fourth and last alternative is to support a dialectical monism (Schelling, Hegel). It is well known that, of these four alternatives to the self-interpretation crisis of modern subjectivity, the first ultimately had a more lasting influence on the philosophical scene, marking, point to point, this last breath of modernity that some call post-modern and flowing into the present situation of “hyperincommensurability” between subjectivity and nature diagnosed by Bruno Latour. The crisis of subjectivity thus becomes a crisis of philosophy, which ends a hostage to the syndrome of the house taken.
A estrutura do noema e a dupla concepção do objeto intencional em Husserl
Authors: Tourinho Carlos Cortes
Published: April 2019

O presente artigo aborda a especificidade do vivido intencional e a sua relação com as sensações não intencionais. Em seguida, examina a relação entre a noese e o noema, além de analisar a estrutura completa do noema. Mostra que o objeto intencional oscila entre o caráter imanente do noema e o que transcende o próprio noema. Ele traz como conclusão, então, que a análise da estrutura completa do noema evidencia uma dupla concepção do objeto intencional na subjetividade transcendental.
Somos livres... mais ou menos – Sobre o desenvolvimento sistemático dos graus de liberdade
Authors: Stederoth Dirk
Published: April 2019

Referindo-se a perpétua estereotipia da história da filosofia, relativa à questão da liberdade do ser humano, respondida com um simples “sim” ou “não”, visa o presente texto apresentar uma abordagem que permite responder a pergunta com “mais ou menos”. Para esse propósito, o conceito de “graus de liberdade” colocado em foco nesta abordagem se desdobra em três dimensões distintas, da qual a primeira é baseada em diferentes níveis cognitivos. A segunda dimensão diferencia quatro fases de ação – e, portanto, fases de liberdade – e, finalmente, em terceiro lugar, são realizados um dimensionamento e graduação em relação a diferenciados níveis de desenvolvimento psicológico. Na última parte, o valor heurístico desses dimensionamentos individuais em relação ao problema da responsabilidade escalonada é ilustrado através de um exemplo.
A construção interpessoal do sentido moral de verdade: considerações sobre a filosofia do jovem Nietzsche
Authors: Muniz Garcia André Luis
Published: April 2019

O presente artigo busca apresentar a perspectiva do jovem Nietzsche em Verdade e mentira em sentido extramoral, segundo a qual o sentido moral de verdade é construído a partir de convencionalização e regulamentação das práticas e dos usos (outrora arbitrários) dossignos linguísticos. Para cumprir essa tarefa, pretende-se dividir o texto em três argumentos principais: (i) Nietzsche e o estatuto da linguagem natural para o pensamento filosófico: metáfora como fator subjetivo da significação, (ii) uso e significação: a construção interpessoal do sentido moral de verdade e (iii) o que é moral no registro do simples pensar?
Poder e limites da razão em Agostinho
Authors: Sérvulo da Cunha Mariana Paolozzi
Published: April 2019

Neste artigo, focalizamos o poder e os limites da razão em Agostinho, perguntando-nos como a razão, interrogando-se sobre si e sobre o que é o ser humano, revela simultaneamente o conhecimento e a ignorância de si. Embora para Agostinho a razão seja o que possuímos de mais elevado, o que nos diferencia dos animais, e o que, juntamente com a memória e a vontade/amor, nos torna semelhantes a Deus,ela não basta à compreensão da realidade e sequer compreende-se totalmente. Para examinar o alcance e os limites da razão (e, em última análise, a superação de si) no pensamento de Agostinho, partimos do “Quaestio mihi factus sum” (“Tornei-me para mim mesmo umainterrogação”, Confessiones X, xxxiii, 50) e seguimos algumas etapas de sua metafísica da experiência interior. Argumentamos que, paraAgostinho, o ser humano em seu autoconhecimento é como que incessantemente retirado de si e reapresentado a si mesmo, em uma espécie de esconde-esconde da consciência de si: ele vê e não vê a si mesmo, compreende algo, mas não tudo de si. A potência e aslimitações da razão, quando analisadas sob a ótica do conhecimento de si, podem ser compreendidas à luz da relação consciência/inconsciência de si e do papel da memória.

Resultados. Los resultados muestran que la escala cuenta con un nivel adecuado de validez y confiabilidad, que el cambio de formato facilita su diligenciamiento y que es necesario ratificar si existen diferencias de sexo que deben ser estudiadas.
La(s) masculinidad(es) en juego bajo la experiencia migratoria de ex braceros de Telchac Pueblo, Yucatán
Authors: Be Ramírez Pedro Antonio , Salinas Boldo Claudia
Published: April 2019

En este artículo se analizan las experiencias que los hombres de Telchac Pueblo, Yucatán, elaboran con respecto a su(s) masculinidad(es) a partir de su incursión como trabajadores agrícolas en el Programa Bracero (1942-1964) propuesto entre México y Estados Unidos. Mediante un estudio de corte etnográfico con entrevistas a profundidad, diálogos con informantes clave y observación participante realizada en el lugar de origen, se analizan las narrativas que los telchaqueños elaboran sobre su experiencia como hombre aventurero, audaz, proveedor, pero también considerado desechable, inservible y “de segunda”, durante los últimos años en operación de este programa binacional. Se concluye con algunas reflexiones acerca de la forma en la que la hegemonía patriarcal opera en los cuerpos, las creencias y las formas de relación entre los telchaqueños y sus familias; cuya masculinidad heteronormada se desliza entre las fronteras físicas, sociales y/o simbólicas.
Alteridades que nos rescatan de lo uniforme: ¿cómo escapar de un mundo de iguales?
Authors: Bard Wigdor Gabriela
Published: April 2019

El presente ensayo es el resultado de años de búsqueda personal como investigadora feminista y a la vez fruto de una apuesta colectiva entre pares, por generar conocimientos que aporten a procesos de emancipación de los sectores más vulnerados por el sistema y vislumbrar que las transformaciones más profundas no las hemos conseguido. La impotencia dio paso a un momento de frustración y, posteriormente, a la revelación de que ningún cambio es posible sin trabajar primero con los propios paradigmas y estilos de vida opresivos. Por medio de este escrito, pretendo reflexionar sobre mis propios procesos de vigilancia epistémica y las apuestas colectivas por transformar la realidad, los condicionamientos estructurales que producen cansancio, depresión y que responden a un orden capitalista esencialmente productivista. Asimismo, debatir acerca de las teorías y metodologías con las que pretendemos generar saberes emancipatorios y luego abordar la reflexión final, donde sostengo, desde un enfoque feminista decolonial, un intento de definición del amor tanto como afecto y como vínculo perdurable con las personas que consideramos alteridades, en tanto son las que pueden salvarnos de la reproducción acrítica del conocimiento y del aislamiento al que nos somete la sociedad capitalista cisheteropatriarcal.
Two new species and new records of Platystele (Pleurothallidinae: Orchidaceae) from Los Cedros Reserve in Ecuador
Authors: Baquero R. Luis E. , Verkovitch Denisse Galarza
Published: April 2019

Two new species of Platystele were discovered at the orchid-rich forest of Los Cedros Reserve at North-west Ecuador. Many species of orchids grow in these forests and some endemic to it. Platystele cedriensis is similar to P. rhinocera from which it differs in the horizontal to descending inflorescence and the three-veined dorsal sepal. Platystele decouxii presents flowers with a unique heart-shaped lip with a heart-shape depression in the blade of the lip. We warn that on-going mining activities and concessions put in risk these and other endemic species from Los Cedros Reserve.

Key words: Carchi, Orchidaceae, Platystele cedriensis, Platystele decouxii, sympatric species

Фразеологічні інновації української мови в медіалінгвістичному висвітленні*
Authors: СИЗОНОВ ДМИТРО
Published: April 2019

This paper focuses on interpretations of the term phraseological innovations or new phraseology. According to international stylistics, the latter are considered fixed linguistic units of idiomatic nature. The author presents the main conceptions of research targeting new phraseological units, and reviews the main sources of origin of new phraseological constructs, particularly those which are related to mass media. Conditions of functioning of new media phraseological units as sociopolitical, ethnographic, cultural, and educational markers are also considered. New phraseological constructs are analyzed in the scope of functional, stylistic, cognitive, and psycholinguistic aspects, which proves the topicality of this field of linguistic research. Particular focus is made on extralingual and intralingual factors causing creation of new phraseological units. Conditions stimulating wider use of phraseology in the mass media and its influence on Ukrainian language evolution are investigated in the paper.
Verb forms / constructions in the Prešov variant and the Bačka-Srem variant of the Rusyn language*
Authors: Fejsa Mihajlo P.
Published: April 2019

There are four variants of the Rusyn language: the Bačka-Srem variant (in Serbia and in Croatia), the Prešov variant (in Slovakia), the Lemko variant (in Poland), and the Transcarpathian variant (in Ukraine). The author of this paper compares the verb forms /constructions in the Bačka-Srem variant of the Rusyn language (South Rusyn / Ruthenian; руски язик) and the Prešov variant of the Rusyn language (West Rusyn; русински язик) and determines the similarities and differences between them. The work essentially represents one of the rare comparisons of a language segment of the existing Rusyn language variants and the author pleads for comparing other language segments too, including the respective language segments of the Lemko variant and the Transcarpathian variant, which could lead to a wider comparative project on an international level. The comparison of the verb forms / constructions in the Bačka-Srem and the Prešov literary standard is based on contemporary grammars.

Published: April 2019

In the present paper, the peculiarities of G. Grebenshchikov’s American text are analyzed from a theoretical point of view and metaphor is considered as a cognitive mechanism. The authors’ metaphoric models serve as a key for understanding the writer’s intention and help to overcome the difficulties of perception of the writer’s text. The metaphors “America – Mechanism” and “America – Organism” are revealed and compared. Grebenshchikov’s conceptual blend “American Babylon” is reconstructed. The research was carried out on the basis of archive documents from the writer’s personal materials.
Ungarische bezüge in der Prager Zeitschrift Ost und West (1837–1848)
Authors: Rózsa Mária
Published: April 2019

The German cultural periodical Ost und West was published in Prague between 1 July 1837 and 10 June 1848. The goal of its editor, the librarian Rudolf Glaser was the mediation between East and West from Austria, Germany, Russia, and the Balkan countries. A lot of articles were published on Czech, Moravian, Russian, and Polish literature, but the culture of other countries was also mentioned in the form of novels, dramas, poems, travelogues, and other genres about regional matters, music, theatre, etc. Its target readers were the educated bourgeoisie of the age. The literary contributions in Ost und West were submitted by authors. Czech folk poetry played a special role among the subjects. Every now and then, Hungarian authors’ works were included (e.g. Pál Jámbor’s poem and Károly Kisfaludy’s novel) in German translation. Karl Georg Rumy, the enthusiastic collaborator of many German-language papers of the Central European region and a zealous propagator of Hungarian literature sent reports to the journal on several occasions. The reviews of the young Frigyes Szarvady also appeared in Ost und West. Julian Chownitz, among others, reported on local curiosities.
Das toponymische Erbe der Habsburgermonarchie in Galizien
Authors: WŁOSKOWICZ WOJCIECH
Published: April 2019

The paper discusses the influence of the Habsburg topographic surveys and cartography on the toponymic landscape of the former crown land of Galicia. Publicly available maps have had a great impact on the geographical names used both by locals and non-locals. The Habsburg toponymic policy was characterized by non-Germanisation of already existing Galician toponyms. The Habsburg toponymic heritage is therefore of double nature: 1) forms of toponyms popularized by Austro-Hungarian maps (especially by Spezialkarte) influenced a wide toponymic usus as well as the toponymy of the later maps (especially interwar-Polish military maps) – these popularized forms may have differed from the names used by the local communities, which could have been caused by a surveyor’s mistake; 2) the topographic and cartographic materials produced by the Austro-Hungarian institutions are a valuable source for toponomastic research. In the paper, the Austro-Hungarian and interwar-Polish topographic manuals are analysed. These documents defined the way a surveyor had to collect and process geographical names. The examples and possible causes of some Polonized forms occurring in Spezialkarte are discussed. Next, the influence of the Austrian maps on the toponymy of Polish maps is explained. Finally, hilarious examples of cartographic name-copying are given.
A contrastive analysis of Hungarian and Croatian idioms containing the component head
Authors: PAŠKVAN NINA SPICIJARIĆ
Published: April 2019

This paper analyzes selected examples of idioms containing the component head in Croatian and Hungarian. Despite the fact that Hungarian and Croatian are not cognate languages, due to the universal experiences and to the fact that they belong to a common cultural circle, these languages have a large correspondence in their phraseology, which can be seen in somatic idioms as body parts represent a kind of universality. The aim of this paper is to show similarities and differences in lexical content and meaning of Croatian and Hungarian idioms containing the component head. The motivational basis of idioms is also discussed as well as the influence of basic and transferred meanings of the lexeme head on the meaning of idioms.
THE RELATIVE AUTONOMY OF JEFFREY ALEXANDER
Authors: Norton Matthew
Published: April 2019

Abstract The strong program in cultural sociology is distinctive in contemporary U.S. sociology. At a time when middle-range theory dominates, the strong program in some respects follow an older model of theorizing through the development of a self-consciously programmatic theoretical endeavor. The article traces this quality of the strong program to its relationship to older theoretical traditions that inspire its ambitions (though it differs from these in important ways). Another aspect of the strong program that exerts an important influence is its institutional identification with the Yale Center for Cultural Sociology. The article focuses on the Center's weekly culture workshop as a nexus that allows for it to both pursue a distinctive theoretical program that nonetheless remains closely connected to developments in U.S. cultural sociology more generally.
Buen vivir y solidaridad económica en Villa del Carbón, México. Racionalidades en disputa
Authors: López-Córdova Dania
Published: April 2019

Propósito: este artículo tiene como finalidad presentar algunas reflexiones sobre la solidaridad económica y el Buen Vivir a partir de los hallazgos encontrados en un pequeño municipio cercano a la capital del país. Descripción: Villa del Carbón es un municipio predominantemente “rural” pero por su ubicación, ocupa un lugar de interface -es un puente entre dos importantes regiones del país, donde se articulan diversos tiempos y espacios, con una complejidad que ilustra tensiones entre racionalidades: por un lado, los procesos de metropolización y “desarrollo” con su racionalidad instrumental y por otro, la permanencia y actualización de los modos de vida basados en racionalidades reproductivas, solidarias y liberadoras. Punto de vista: se sostiene que existen experiencias de solidaridad económica –organizaciones productivas forestales, apícolas, agroecológicas, ecoturísticas-, sin embargo, las mismas están amenazadas y tensionadas de manera permanente por las exigencias del “desarrollo” y el capitalismo. Conclusiones: Los rasgos de las prácticas de solidaridad económica, que encarnan racionalidades alternativas, racionalidades otras, deberían ser considerados para diseñar y aplicar políticas públicas de promoción y fortalecimiento.
Diferencia en campo: prácticas económicas y Amefricanidade de las Baianas de Acarajé contra FIFA
Authors: Da Silva Araujo Larissa
Published: April 2019

Propósito: el artículo presenta algunas reflexiones resultantes de una investigación sobre la disputa entre Baianas de Acarajé en contra de la FIFA, organismo rector del futbol mundial. Descripción: con la realización del Mundial de Fútbol de la FIFA en 2014, se implementó en Brasil el “modelo de desarrollo por mega eventos”, que resultó en la violación de derechos humanos de muchos brasileros, entre ellos las Baianas de Acarajé. Esas mujeres, trabajadoras callejeras que fueron impedidas de trabajar en las llamadas “zonas de exclusión de la FIFA”, resistieran para que su oficio, actividad realizada hace siglos, fuera respetado como forma económica autónoma. Punto de vista: en ese sentido, para desafiar al frente estatal-empresarial que se estableció en el país, realizaron varias estrategias de lucha que fueron de la negociación a la acción directa. Conclusiones: a partir de los hallazgos de la investigación en campo, según una perspectiva interseccional y descolonial, presento algunos aspectos de esa disputa y las características de la racionalidad económica de las Baianas de Acarajé.
El Cooperativismo y la Economía Solidaria: Génesis e Historia
Authors: Ramírez-Díaz Luis Francisco , Herrera-Ospina José de Jesús , Londoño - Franco Luis Fernando
Published: April 2019

Propósito: el presente artículo realiza una revisión sistemática del pensamiento filosófico en función de los comienzos de la economía solidaria, en los contextos internacional y nacional. Descripción: Actualmente el desarrollo de la economía globalizada exige nuevos escenarios que involucren el pensamiento y la praxis en las diferentes actividades que constituyen el quehacer de los seres humanos. Punto de vista: en consecuencia el objetivo del artículo se fundamenta en dar una mirada al desarrollo teórico que se puede leer desde las diferentes corrientes expuestas en el tiempo en torno a la economía solidaria, como una respuesta a las crisis sociales que han acompañado el trascurrir de la humanidad. Conclusiones: la solidaridad a lo largo de la historia se ha venido constituyendo en una base de desarrollo social que busca la equidad, la justicia y la sostenibilidad de los individuos, lo cual se describe a lo largo de este trabajo. Esto con el ánimo de establecer la caracterización del pensamiento solidario como base para el progreso de las comunidades en el contexto actual, tal como lo expresa DANSOCIAL (2005).
La educación en Colombia: dinámica del mercado y la globalización
Authors: Rubiano - Aldana Diego Alejandro , Beltrán - Jiménez Harold
Published: April 2019

Propósito: este artículo tiene como propósito presentar una reflexión y construir una interpretación desde la perspectiva del paradigma hermenéutico histórico para generar procesos de comprensión sobre el fenómeno social de la mercantilización de la educación. Descripción: desde el año de 1991, con la reforma constitucional, la educación en Colombia se reconoce como derecho fundamental. Sin embargo,  este proceso estuvo acompañado por la llegada de las nuevas tecnologías de la información y la comunicación, en donde la educación e-learning en conjunto con el sistema de franquicias conformó un modelo de negocio que se sitúa en el mercado educativo del país como alternativa y estrategia para el desarrollo económico. Punto de vista: esta relación termina incidiendo en la garantía del derecho a la educación al vincular el acceso y su calidad a las posibilidades económicas. Conclusiones: en Colombia se sigue asumiendo el proyecto educativo del país desde la coyuntura.  La planeación a mediano y largo plazo no hace parte de una política pública coherente, porque siempre hay otras prioridades en la asignación presupuestal. Esto en un país inequitativo como Colombia implica convertir la educación en un factor que incrementa la desigualdad y no en lo que debería ser: un factor de equidad.
El observatorio, una herramienta para el sector social, cooperativo y solidario en la región Tolima
Authors: Rivera - González Miguel Ángel , Rubiano - Aranzales Edicson
Published: April 2019

Propósito: el presente estudio consiste en dar cuenta sobre un observatorio como herramienta al sector social, cooperativo y solidario en el departamento del Tolima. Descripción: el observatorio como una herramienta para el sector social, cooperativo y solidario se crea teniendo en cuenta que la región Tolima goza de organizaciones que desarrollan fines de beneficio colectivo o social, y su único propósito es el mejoramiento de las condiciones de vida de sus cooperados o el mejoramiento de la calidad de vida de las comunidades,  las cuales sustentan la creación del observatorio para que propenda por procesos continuos en educación, formación, asistencia técnica e investigación y así contar con mejores estándares de cohesión, integración, articulación, visibilización, productividad, competitividad, innovación y emprendimiento. Punto de vista: la ausencia de información para tomar decisiones y generar acciones colectivas es una de las aristas que impide reconocer el quehacer de las organizaciones en el medio y en el entorno.  Conclusiones: si bien es cierto que un observatorio tiene muchas características, es necesario pensarlo en red, en la que el trabajo colaborativo sea el eje fundamental de la construcción desde aspectos como la multiculturalidad, y la multidisciplinariedad.

Geochemical Characteristics of Sunda Volcanic Arc in Sumatra and Andaman
Authors: Kurnio Hananto
Published: April 2019

DOI: 10.17014/ijog.6.1.1-16Geochemical characteristics of Sunda volcanic belt are recognized from each characteristic of Weh Island, Tabuan Island in Semangko Bay, South Sumatra, and Andaman Islands. Trace and rare earth elements (REE) are produced by fumaroles in a marine environment of submarine volcano of Weh Island characterized by barium (Ba) as an indicator of sea water influence in the mineralization process, while sulphide minerals do not occur in this area. REE pattern compared to Mid Oceanic Ridge Basalt (MORB) shows a characteristic of subduction tectonics and is distributed in shallow coastal water of high energy. Based on comparison of REE contents in all samples, it reveals that volcanism process causes REE enrichments either in the past or in recent. Geochemical characteristics of Tabuan Island in Semangko Bay reveal the occurrence of hydrothermal mineralization followed by pervasive occurrences of sulphide minerals in vein-type disseminations enriched in Au, Ag, Zn, Pb, Cu, As, Sb, Ba, and Mn. Geochemical characteristics of Andaman Islands reveal imprint of substantial subduction component in the form of sediment fluid and melt and fluid-induced subduction component derived from altered oceanic crust.
The Ancient Borobudur Lake, History, and Its Evidences to Develop Geo-archeotourism in Indonesia
Authors: Murwanto Helmy , Purwoarminta Ananta
Published: April 2019

DOI: 10.17014/ijog.6.1.103-113In 2015, the number of international tourists who visited Borobudur temple declined and did not reach the government target. It was because there was only one attraction in the temple. After visiting Borobudur, most of tourists move to another place such as Yogyakarta. They know about the temple, but not its past environment when the temple was built. The history and past environment of Borobudur temple could be developed as additional tourist attractions to make them stay longer in that area. Geological condition and the evidences of an ancient lake could be developed as tourist objects. It is very interesting and could be developed to educate visitors in geo-archeology. The aim of this research is to develop archeological (temple) tourism based on geology and past environment. Although many researches on geo-archeology have been done, the results which relate to tourism are still not widely applied yet. The methods used are secondary data analysis and a field survey to investigate the potential of tourist stop sites. The potential tourist attractions were determined by geomorphology, lithology outcrops, stratigraphy, environment, and accessibility. The result is ten stop sites which could be used to describe the paleoenvironment in Borobudur based on geosciences. These tourist objects could explain the environment in the past related to the temple reliefs and ancient human activities.
Study of Seawater Intrusion in Deep Aquifers of Semarang Coast Using Natural Isotopes and Hydrochemicals
Authors: Wijatna Agus Budi , Kayis Muhammad , Satrio Satrio , Pujiindiyati Evarista Ristin
Published: April 2019

DOI: 10.17014/ijog.6.1.17-28Seawater intrusion in deep aquifers of Semarang Coast is important to be investigated, because Semarang is one of big cities in Indonesia. Besides its dense population, the growth of industries also increases rapidly with the increase of withdrawal of groundwater either from shallow or deep aquifers. Over-exploitation of groundwater can cause a decreasing groundwater quality due to seawater intrusion. Through this study, the salinization from seawater into the deep aquifer system can be observed. Groundwater samples were collected from deep aquifers with the depth around 40-120 m, and then the isotope contents of 18O and 2H as well as the hydrochemical were analyzed. The isotope and hydrochemical analysis results show that six of thirteen samples are of freshwater type. They are in S2, S5, S7, S8, S9, and S13 sites. While the others are supposed to be encroached by seawater. The slight encroached groundwater of S1, S6, and S10 had a fraction of seawater in the range of 0.15 to 0.26, whereas the moderate and high ones were of S3, S4, S11, and S12 which had seawater fraction between 0.25 and 0.34. Seemingly, salinization mechanism of groundwater by seawater does not depend on its distance from the shoreline and bore well depth. It is confirmed to the site of S5 and S7 located 680 m and 950 m from the shoreline, respectively, which were predominated as freshwater type. On the contrary, the groundwater of S10, S11, and S12 located at further sites about 5-6 km from shoreline is clearly indicated seawater intrusion.
Late Holocene Pollen Record of Environmental Changes in Karimata Strait, Sunda Shelf Region
Authors: Yulianto Eko , Sukapti Woro Sri , Dewi Kresna Tri
Published: April 2019

DOI: 10.17014/ijog.6.1.41-55Pollen analysis has been conducted on a 90 cm gravity core taken from the Karimata Strait to reveal pollen facies in marine sediment and Late Holocene environmental changes in the central Sunda Shelf region. The core site is at 32 m water depth and located about 170 km northwest of Bangka Island, Indonesia. Ten samples were collected at 10 cm intervals through the core. The total number of pollen grains counted in the samples varies between very low (<50 grains) to abundant (>200 grains). High frequencies (50 - 70%) of mangrove pollen are found at 90 to 40 cm indicating that pollen facies in offshore marine sediment may be comparable with those in mangrove forest floor sediment. The core site has been in a neritic environment since its early deposition ca. 1,800 yr B.P. (~150 A.D.) when mangroves vastly grew on the tidal flats of the surrounding islands and they persisted to ca. 700 yr B.P. (~1,250 A.D.). In the middle of this period, a catastrophic event speculatively due to the 535 A.D. Krakatau eruption might have responsible for the decrease of mangroves and the disappearance of benthic foraminifers. The deposition of silicious materials (tephra) due to this eruption might have provided an opportunity for benthic foraminifers to increase their population subsequently. From ca. 700 yr B.P. (~1,250 A.D.) mangroves declined, as indicated by lower frequencies of pollen grain in samples from 30 cm deep upward. It occurred simultaneously with the deposition of coarser sediment and the increase of benthic foraminifer abundance. Interplay of anthropogenic activities, strengthening ENSO cycle, and lowering erosion base level might have been responsible for these environmental changes.

An algorithm of adaptive estimation of the magnetic flux for the non-salient permanent magnet synchronous motor (PMSM) for the case when measurable electrical signals are corrupted by a constant offset is presented. A new nonlinear parameterization of the electric drive model based on dynamical regressor extension and mixing (DREM) procedure is proposed. Due to this parameterization the problem of flux estimation is translated to the auxiliary task of identification of unknown constant parameters related to measurement errors. It is proved that the flux observer provides global exponential convergence of estimation errors to zero if the corresponding regression function satisfies the persistent excitation condition. Also, the observer provides global asymptotic convergence if the regression function is square integrable. In comparison with known analogues this paper gives a constructive way of the flux reconstruction for a nonsalient PMSM with guaranteed performance (monotonicity, convergence rate regulation) and, from other hand, a straightforwardly easy implementation of the proposed observer to embedded systems.

The parametric structural schemes, structural-the parametric models and the transfer functions of the electroelastic actuators for the nanomechatronics systems are obtained. The transfer functions of the piezoactuator are determined under the generalized piezoelectric effect. The changes in the elastic compliance and the stiffness of the piezoactuator are found, taking into account the type of control. The decision wave equation and the structural-parametric models of the electroelastic actuators are obtained. Effects of the geometric and physical parameters of the electroelastic actuators and the external load on its static and dynamic characteristics are determined. The parameteric structural schemes for the electroelastic actuators for the nanomechatronics systems are obtained. The transfer functions are determined. For calculation of the automatic control systems for the nanometric movements with the electroelastic actuators are obtained the parametric structural schemes and the transfer functions of actuators. Static and dynamic characteristics of the electroelastic actuators are determined. The application of electroelastic actuators solves problems of the precise matching in microelectronics and nanotechnology, compensation of temperature and gravitational deformations, atmospheric turbulence by wave front correction. By solving the wave equation with allowance for the corresponding equations of the piezoelectric effect, the boundary conditions on loaded working surfaces of the electroelastic actuator, the strains along the coordinate axes, it is possible to construct the structural parametric model of the actuator. The transfer functions and the parametric structural schemes of the electroelastic actuator are obtained from the equations describing the corresponding structural parametric models and taking into account the opposed electromotive force of the electroelastic actuator for the nanomechatronics systems.
Modeling of Dynamics of Land Boat Based on the Magnus Effect
Authors: Ishkhanyan M. V.
Published: April 2019

The motion of a wind powered land boat is studied. It is supposed that the land boat moves along a straight line in a steady horizontal wind flow. The axis of rotation of the Savonius rotor is vertical. The rotation of the Savonius rotors induces the Magnus force that maintains the motion of the load boat. Such vehicles can be used to perform transportation in large open areas, where there is an access to free wind. In this paper, the mathematical model of the land boat driven by the Savonius rotor is constructed. The quasi-steady approach is used to describe the aerodynamic action upon the system. Corresponding aerodynamic coefficients are approximated basing on experimental data. The angle between the wind velocity and the velocity of the boat is a varied parameter of the model. The equations of the model are presented as a dynamic system of the second order. The conditions of existence and stability of stationary modes of the dynamic system motion are obtained. It is described how the boat speed at steady motion depends upon the angle formed by the velocity of the boat and direction of the wind. In particular, it is shown that the maximum of the boat speed is achieved on the close-hauled course, that corresponds to the recommendations of the sail settings known in sea navigation.

In this article it is described the operation principle of a robotic manipulator ARMino device and the connection diagram of its electrical components. The device includes: An Arduino Mega control board, four servos, four potentiometers, a prototyping board, a computer. Turning the shafts on the potentiometer adjusts the position of the servo spindles. When the voltage on the potentiometer’s pin changes, the voltage at the analog inputs of the microcontroller changes. Then, in the microcontroller, the voltage is scaled to the value of the servo rotation angle. After that, the joints of the robotic manipulator are rotated. During the operation of the ARMino robotiсarm, a contact bounce problem appeared, significantly reducing the accuracy of positioning and the smooth movement of the ARMino joints. To solve this problem, a digital filter was developed. This article describes the digital filter working algorithm, which consists of four steps. One of the steps consists on finding the digital filter coefficients, which regulate the signal voltage level transmitted to the servo motors, and its transition process time which forms the signal edge. The main problem developing a digital filter is that the standard procedure of finding the digital filter coefficients, the coefficients are given by a recommended range of values, which complicates choosing from this range, a single value and transmitting it to the servos. To solve this problem, a fuzzy digital filter was developed, the algorithm of which consists of six steps. The first step determines the input variables degree of truth. The second step is to calculate the degrees of truth of the fuzzy rules preconditions. The third step is to calculate the degrees of truth of the fuzzy rules conclusions by using the process of finding the maximum values. The fourth step is the defuzzification stage in which a precise value of the fuzzy digital filter coefficient is calculated. The fifth step is the output voltage transmitted to the servos. In the sixth step, the output voltage in the microcontroller is converted to the angle value and the servo is given the command to rotate. This article presents numerical simulation of the fuzzy digital filter algorithm, using as an example the servo responsible of the ARMino base rotation. Experimental studies on the functioning of the fuzzy digital filter have been carried out, confirming the expediency of its use. The graphics of the transition process of the robotic manipulator base movement without and with the use of a digital filter are given.
Synthesis of the Missile Homing System Taking into Account the Dynamic Characteristic of the Measurement Elements

Published: April 2019

Several various missile homing systems (MHS) have been developed in recent years. However, to the best of our knowledge, these systems do not take into account the dynamic characteristics of the measurement elements (ME). Such existing systems can only work well when the MEs have a small inertia and large damping. Thus in general case, it is necessary to consider the dynamic characteristics of the MEs with the big inertia. In addition, using the MEs with the big inertia, the MHSs is able to remove the high-frequency noise. However, taking into account the dynamic properties of the MEs causes difficulties in determining the transfer function (PF) of the normal acceleration stability system and the synthesis of MHSs. Therefore, in this paper, we propose an effective mathematical model of the missile homing system, which takes into consideration the dynamic characteristics of the MEs. In addition, this model allows synthesizing the high accuracy MHSs, and utilizing the MEs with the inertia equivalent to the inertia of the rudder actuator. To accomplish that, the proposed system is composed of two stages. In the first stage, the MHSs, which do not incorporate the dynamic characteristics of the MEs, is presented in detail. Then, we analyze and estimate the effect of the dynamic characteristics of the MEs on the performance of the MHSs. In the second stage, we propose a novel MHS, which takes into account the dynamic characteristics of the MEs. The proposed system is implemented based on the basic functions in the Control system toolbox in MATLAB, and designed by the parametric optimization method. The simulation results indicate that, our proposed system outperforms the conventional MHSs in term of reducing the negative effects of the dynamic characteristic of the MEs on the quality of the MHS.

Published: April 2019

BackgroundLate-onset preeclampsia (PE) is preeclampsia occurring after 34 weeks of gestational age or later.  Cullin 1 (CUL1), a proangiogenic protein, is expressed in the placenta, where an imbalance between proangiogenic and antiangiogenic proteins during gestation can cause disturbance of trophoblast invasion. This defect results in vascular ischemia that may produce preeclampsia. The objective of this study was to determine the correlation between CUL1 as proangiogenic factor and late-onset preeclampsia. MethodsThis study was of analytical observational cross-sectional design and involved 44 preeclampsia patients with ³34 weeks of gestational age (late-onset PE). The CUL1 level in the subjects’ sera, taken before they gave birth, and in homogenates of their placenta, obtained per vaginam or by cesarean section, were examined by the ELISA technique.  Statistical analysis was performed with the Spearman correlation test with significant p value of <0.05.ResultsMedian maternal age was 31 years and median gestational age was 37 weeks.  Median serum CUL1 was 41.78 pg/mL and median placental homogenate CUL1 was 32.24 pg per milligram of total placental tissue protein. There was no significant correlation between serum CUL1 level and late-onset preeclampsia (r=-0.281; p=0.065). There was also no significant correlation between placental CUL1 level and late-onset preeclampsia (r=-0.166; p=0.281).ConclusionSerum CUL1 and placental CUL1 were not correlated with late-onset preeclampsia. However, this study indicated that low serum CUL1 tends to prolong gestational age in preeclampsia.

Background: In Chronic kidney Disease (CKD) a significant risk factor for mortality is Cardiovascular disease (CVD) and the most prevalent cardiovascular risk factor is left ventricular hypertrophy (LVH). Anemia, hypertension and volume overload are risk factors for LVH in CKD. So, the present was aimed at comparing the risk factors between CKD with and without LVH.Methods: A cross sectional study carried out over a 2 year period in Department Nephrology and General Medicine OPD, MIMS, Vizianagaram, Andhra Pradesh. A total of 120 patients are included in this study and divided in to CKD stage III to V based on estimated GFR. Based on 2D echocardiography data CKD cases are further divided in to CKD with LVH and CKD without LVH.Results: The Left ventricular mass index was significant higher in CKD with LVH (128.89±19.28) when compared with CKD without LVH (108.20±10.28). The left ventricular mass index was noted in more number in stage V of CKD. It is also observed that the left ventricular mass index was negatively correlated with haemoglobin and eGFR and was positively correlated with systolic blood pressure and serum NT-proBNP.Conclusions: Present study finding suggested that the incidence of LVH is higher in CKD patients. LVH was positively correlated with hypertension and NT-proBNP and negatively correlated with anemia and estimated GFR.
