Passive Friction Compensation Using a Nonlinear Disturbance Observer for Flexible Joint Robots with Joint Torque Measurements
Authors: Le Luc Tien
Published: March 2019

The friction and ripple effects from motor and drive cause a major problem for the robot position accuracy, especially for robots with high gear ratio and for high-speed applications. In this paper we introduce a simple, effective, and practical method to compensate for joint friction of flexible joint robots with joint torque sensing, which is based on a nonlinear disturbance observer. This friction observer can increase the performance of the controlled robot system both in terms of the position accuracy and the dynamic behavior. The friction observer needs no friction model and its output corresponds to the low-pass filtered friction torque. Due to the link torque feedback the friction observer can compensate for both friction moment and external moment effects acting on the link. So it can be used not only for position control but also for interaction control, e.g., torque control or impedance control which have low control bandwidth and therefore are sensitive to ripple effects from motor and drive. In addition, its parameter design and parameter optimization are independent of the controller design so that it can be used for friction compensation in conjunction with different controllers designed for flexible joint robots. Furthermore, a passivity analysis is done for this observer-based friction compensation in consideration of Coulomb, viscose and Stribeck friction effects, which is independent of the regulation controller. In combining this friction observer with the state feedback controller \cite{Albu-Schaeffer2}, global asymptotic stability of the controlled system can be shown by using Lyapunov based convergence analysis. Experimental results with robots of the German Aerospace Center (DLR) validate the practical efficiency of the approach.

Authors: ODEKANYIN Oludele Olayemi , KAYODE Atinuke Shakirat , ADEWUYI Joseph Olufemi
Published: March 2019

The study investigated the presence of lectin in the seeds of Pterocarpus soyauxii, purified the lectin and determined its physicochemical properties as well as its antioxidant potential. Purification of P. soyauxii seeds lectin (PSSL) was accomplished by ammonium sulphate precipitation and gel filtration on Sephadex G-100, hemagglutination assay was by serial dilution and DPPH radical scavenging, metal chelating and lipid peroxidation inhibition assays were employed to evaluate its antioxidant potential. PSSL agglutinated erythrocytes from human blood group ABO, rabbit and rat. Trypsinization enhanced agglutination which was inhibited by galactose, lactose and arabinose. The lectin activity was independent of metal ion, thermal stable up to 60 °C and at pH range of 6 to 8. Gel filtration estimated molecular weight was 65 kDa and subunit molecular weight was 35 kDa. PSSL showed significant antioxidant activity. The lectin was able to scavenge DPPH radical, chelate iron metal and inhibit lipid peroxidation with IC50 of 0.14 ± 1.33 mg/ml, 3.40 ± 0.37 mg/ml and 0.50 ± 0.08 mg/ml respectively. The results indicate that PSSL might be applied as natural antioxidant for the development of drug and food products for the benefit of human health.
Theoretical model for micro-nano-bubbles mass transfer during contaminant treatment
Authors: Xia Zhiran , Hu Liming
Published: March 2019

Micro-nano-bubbles (MNBs), in particular ozone and oxygen MNBs, represent an innovative method for wastewater treatment and groundwater remediation. Although several models have been developed to describe the fate of MNBs in water, a theoretical model describing the mass transfer processes of MNBs during treatment of contaminants has not been adequately developed. In this study, a theoretical model considering the decomposition and reaction of dissolved gas is proposed based on the Epstein and Plesset theory, aiming to describe mass transfer processes of oxygen and ozone MNBs during treatment of contaminants. The life of MNBs, volume-weighted average dissolved gas concentration and utilisation efficiency of gas, which are of significant importance in MNB applications, are further studied. The life of MNBs increases with the half-life of dissolved gas, but the impact diminishes. For gases which present a slow consumption rate and a long half-life, the effect of half-life on the life of MNBs is negligible. With controlled total mass of gas, smaller-sized bubbles result in a significantly higher dissolved gas concentration and more efficient treatment of contaminants. The newly developed model can describe the fate of MNBs during treatment of contaminated water and theoretically proves the advantages of MNBs over large-sized bubbles.

Authors: KAPTAN Sinan , DURKAYA Ali
Published: March 2019

Aim of study: In this study, changes in land cover and land use from designing forest management plans within a plan unit up until today in the field of study are analysed under various categories.Field of study: Drahna Forest Subdistrict Directorate (FSD) under Ulus Forest Operation Directorate (FOD) of Zonguldak Regional Directorate of Forestry (RDF) was selected as the field of this study.Material and Method: Forest management plans and forest cover type maps for the related plan unit were utilized in the study. Forest cover type maps for the years 1967-1986 and 1986-2005 were digitized by using Geographical Information System tool ArcGIS version 10.4, whereas forest cover type map for the years 2006-2024 was obtained digitized from the relevant authority.Results: It was found that there was an increase of 227.6 ha in forest land in addition to a decrease of 227.6 ha in non-forest land between 1967 and 2006. It was also determined that there was a decrease of 2,295.33 ha in sparse forest land (with less than 10% canopy closure) whereas an increase of 2,523 ha in productive forest land (canopy closure above 11%). Further, a decrease of 369.91 ha in agricultural land in contrast with an increase of 36.69 ha in treeless forest land (TFL) and of 105.62 ha in settlement land were observed as well in non-forest lands.Emphasis of study: Within a period of 40 years between 1967 and 2006, immigration led to decreases in agricultural land and increases in forest land within the field of this study.
DASH Protocol v2.5 v1
Authors: Lyden Amy , Crawford Emily , Quan Jenai , Caldera Saharai , Dynerman David
Published: March 2019

This protocol is for performing Depletion of Abundant Sequences by Hybridization (DASH) after preparing sequencing libraries and pooling together. DASH is most useful for RNA-seq of human metagenomic samples, where abundant species such as human mitochondrial ribosomal RNAs (rRNAs) occupy a majority of the sequencing space available, leaving a minor fraction for regions of interest. DASH treatment is performed after ligation of adapters and unique barcoding of the RNA-seq library. It employs CRISPR-Cas9 complexed to a set of guide RNAs (gRNAs) targeted to the abundant regions to be depleted in a given library. These abundant regions in the library are then cleaved, leaving only the fragments with intact adapters on both ends to be further amplified and sequenced.
Evaluation of applicability of dielectric constant in monitoring aging processes in engine oils
Authors: Gomółka Leszek , Augustynowicz Andrzej
Published: March 2019

This paper reports on the study involving the development of a dependence between the selected physicochemical properties of
engine oil and the variation of its dielectric constant, considered as an evaluation parameter for the degree of its exploitation.
In order to get to know the selected phenomena that accompany oil aging, a decision was made to perform tests of the condition
of engine oils at various stages of their exploitation. In addition to the analysis of the dielectric constant, measurements of total
base number and (TBN) and infrared spectroscopy (IR) were also performed. The interdependence between the examined values
is developed using the Pearson’s linear correlation coefficient. As a result, the variability of TBN and IR absorbance in the context
of the change in the dielectric constant were evaluated. Following the realized experimental tests, it was found that the results
demonstrate a satisfactory correlation between the selected physicochemical properties of the oil, which resulted in the adoption
of an assumption of a high feasibility of application of dielectric constant as a diagnostic parameter in monitoring the state of
exploitation of engine oil.
The influence of the friction phenomenon on a forest crane operator’s level of discomfort
Authors: Urbaś Andrzej , Szczotka Marek
Published: March 2019

A mathematical model of a forest crane that is suitable for dynamics analysis of its operation cycle is presented in this paper. The
flexibility of the operator’s seat, drives and supports is taken into account. Joint coordinates are applied to describe the motion
of the links together with the homogeneous transformations technique. Lagrange equations of the second order are used when
deriving the equations of motions. Joint forces and torques are determined based on recursive Newton-Euler algorithms. These
joint forces are then used in the LuGre friction model, which allows to calculate the friction coefficients and friction forces. Numerical analyses performed here show the influence of various friction forces on the vibration level as perceived by the operator
of the crane. The level of discomfort is discussed based on standards commonly used in the vehicle and transportation industry for
evaluations of vibration comfort
Crossing the Line between News and the Business of News: Exploring Journalists’ Use of Twitter
Authors: Jukes Stephen
Published: March 2019

Anglo-American journalism has typically drawn a firm dividing line between those who report the news and those who run the business of news. This boundary, often referred to in the West as a ‘Chinese Wall’, is designed to uphold the independence of journalists from commercial interests or the whims of news proprietors. But does this separation still exist in today’s age of social media and at a time when news revenues are under unprecedented pressure? This article focuses on Twitter, now a widely used tool in the newsroom, analysing the Twitter output of 10 UK political correspondents during the busy party conference season. It examines how they promote their own stories or ‘personal brand’ and whether they are stepping over a once forbidden line, blurring the boundary between news and the business. The research is complemented by interviews with political correspondents and analysis of editorial codes of practice on the use of social media. It draws on a conceptual framework of boundary work (Carlson & Lewis, 2015) to pose the question whether such practice has now become accepted and normalised. The findings suggest that the 10 political correspondents are highly individualistic in their use of Twitter but all have embraced its use to promote their own work plus that of colleagues both inside their own organisation and those working for rival news outlets. Their acceptance of Twitter as a tool for self-promotion and branding suggests that in this area of reporting the practice has become normalised and the wall has been breached.

Authors: Pavlova O.
Published: March 2019

The purpose of the work is to formulate the problem of mimesis in terms of semiotic approach and to determine its specific mode of signification. The results of the study were obtained through the application of semiotic and hermeneutic approaches, which allow the complex using of aesthetics tools as to reveal the problem of meaningful generation and the organization of signifiers in the logic of mimesis. On the basis of this scientific research, the authors developed and implemented the working curriculum of the academic discipline "Aesthetics" into educational process of Kyiv National University named after Taras Shevchenko, which is included into the Educational Curriculum "Philosophy" for bachelor degree on the specialty 6.020301 "Philosophy". Originality of this is to reveal mimesis mode of signification through the definition of the ratio of the signifier, the signified and the referent. The results obtained suggest that the development of a semiotic approach reveals the possibility of improving aesthetic component of the professional training of philosophers at Kyiv National University named after Taras Shevchenko.

Authors: Newell Lori
Published: March 2019

Current estimates indicate that 1.5 million Americans have Parkinson's disease (PD), and 60,000 new cases are diagnosed each year. Having PD can interfere with the ability to do everyday activities and hobbies,and generally increases one's tendency to fall. Since there is currently no cure for the disease, treatment is aimed at managing symptoms, working to maintain independent function, and as much as possible reducing PD-related disability. The following article provides an overview of a program offered to those with PD that combines education in body mechanics, fall prevention,low impact aerobics, strength training, and Yoga postures,breathing, and meditation as a way to help manage symptoms and maintain independence.

Published: March 2019

Purpose: This study aimed to evaluate the value of neutrophil/lymphocyte ratio (NLR) together with the demographic characteristics in predicting liver insufficiency or transplantation need following mushroom poisoning. Materials and Methods: The patients were evaluated in terms of various parameters including gender, age, the month of admission, symptoms on emergency service admission, vital findings, laboratory findings, poisoning severity score (PSS) according to initial symptoms, and onset time of symptoms. The patients were divided into two groups according to whether the liver function tests were deteriorated or not. NLR was assessed according to PSS in patients with and without acute liver failure.Results: A total of 84 patients, aged 16-85 years, were included in the study. Neutrophil/lymphocyte ratio was 10.82±8.7 in patients with impaired liver function tests and statistically significant compared to the patients with normal liver function tests (5.66±4.71). NLR was statistically significantly higher in patients who developed acute liver failure and in those with high poisoning severity score. The cut-off value was founded as 9.65.Conclusion: NLR may be a useful predictor of liver failure or transplantation need, which develops as a result of mushroom poisoning.
La protección de los inmigrantes irregulares en los Estados Unidos y la libertad de circulación en una «Unión Americana»
Authors: Campbell Kristina M.
Published: March 2019

Este artículo es una continuación y ampliación de una propuesta que formulé en 2009, y se plantea si —y cómo— los Estados Unidos pueden apartarse de su actual sistema de regulación de la inmigración punitivo, cuasi-penal y de exigencia dura de su cumplimiento. ¿Es posible para los Estados Unidos y sus vecinos acercarse a un sistema de protección de los refugiados y otros migrantes irregulares del resto de las Américas, modelado sobre el concepto de «libertad de circulación» de la Unión Europea? Si es así, ¿a qué debería parecerse dicho sistema? Permitiendo a todos los ciudadanos de una «Unión Americana» el derecho a viajar, vivir, y trabajar en América del Norte, sin los peligros inherentes al actual sistema de fronteras militarizadas de Estado-nación, ¿se forjarían nuevas y más fuertes alianzas entre los Estados Unidos, Canadá y México? ¿Puede —y debería— dicha «Unión Americana» expandirse más allá de los Estados-nación de América del Norte, para incluir el resto de las Américas, así como los ciudadanos América Central y América del Sur?

El comercio electrónico de obras plásticas: aproximación a una realidad en Cuba
Authors: Pérez Orozco Luis
Published: March 2019

El comercio electrónico consiste en la compra y venta de productos o de servicios a través de medios electrónicos, como Internet y otras redes informáticas. Constituye uno de los ámbitos de mayor investigación científica y más actividad en la creación de marcos normativo-legales. Concede en el domicilio de una persona una gran oferta de bienes y servicios de forma sencilla y rápida. Entre esos bienes que se pueden adquirir están las obras de arte. Hoy día, marchantes y galerías de arte cuentan con un sitio en Internet que les permite enlazar con mercados virtuales. El comprador y el vendedor puedan encontrarse rápidamente desde dos ubicaciones geográficas distantes. Cuba es un país que no queda ajeno a esta dinámica, pues los autores de obras plásticas viabilizan la comercialización de sus creaciones utilizando el Internet. Pero, si bien el comercio electrónico representa muchísimas facilidades para el binomio artista-cliente, su uso trae aparejado inconvenientes legales e inseguridad jurídica. Por tanto, la presente investigación se circunscribe a la descripción de la situación de iure y de facto sobre el comercio electrónico de obras plásticas cubanas. Todo ello motivado por una cuestión que cada vez más cobra auge en la práctica: el aumento del interés en el arte cubano, ya sea por inversión o goce estético.
ADN: aproximación a los alcances y límites de la prueba

Published: March 2019

Es evidente que se han alcanzado grandes avances en los últimos años en el campo de la biología genética, pero no significa esto que las modernas técnicas científicas puedan utilizarse sin más para basar sobre ellas la condena o la absolución de un acusado. En última instancia, nos encontramos con un problema de política legislativa. La Constitución de 1978, interpretada por el Tribunal Constitucional, impone un sistema procesal penal revestido de un conjunto de garantías, las cuales pueden chocar en aspectos concretos con el fin de la ciencia natural de alcanzar la verdad de los hechos, y no a cualquier precio, si a un precio distinto al que está dispuesto a pagar el Estado de Derecho. Plantearemos así en el presente trabajo los alcances de esta prueba.
Algunas consideraciones sobre el acceso a la información pública a la luz de la sentencia del Tribunal Supremo (sala 3ª, sección 3ª), núm. 1547/2017, de 16 de octubre
Authors: Rodríguez-Arana Muñoz Jaime , Herce Maza José Ignacio
Published: March 2019

Con la Ley 19/2013 de transparencia, acceso a la información pública y buen gobierno se regula el derecho de acceso a la información pública con detalle y se configura como un derecho subjetivo. Como todo texto normativo, a la hora de su aplicación, genera numerosas dudas interpretativas. Dos de las cuestiones más importantes que se suscitan son las relativas a los límites de acceso a la información y las causas de inadmisión de solicitudes y por fin, el Tribunal Supremo ha dictado una sentencia que arroja algo de luz sobre esta materia. Dicha resolución, junto con la defensa de una Administración transparente, que fomenta la participación y que es acorde con la dignidad del ser humano será objeto de análisis en el presente trabajo.
La polémica en torno a los enterramientos y los suicidas en la España de la Ilustración
Authors: Rodríguez Ennes Luis
Published: March 2019

A partir del siglo XVIII se empieza a difundir la opinión sobre la necesidad de establecer una distancia favorable entre los muertos y los vivos, propiciando los enterramientos en lugares alejados de los núcleos habitados. También, en esa época, se suscita un fuerte movimiento crítico contra la excesiva premura en las inhumaciones. No es de extrañar, por tanto, que se generase un gran debate acerca de los signos de la muerte antes de realizar el sepelio. Por otra parte, siempre se consideró al suicidio como contrario a los principios católicos y, por ende, se le negaba al suicida el entierro en lugar sacro. Fue Feijoo quien se anticipó en más de dos siglos al vigente Código de Derecho Canónico de 1983, eliminando la prohibición de inhumar a quien se quita la vida por considerarlo “enfermo mental” y, por consiguiente, inimputable
Aforamientos e inmunidades. Estudio comparativo de las garantías parlamentarias en México y España

Published: March 2019

El presente escrito tiene como objetivo realizar un estudio comparado entre México y España, respecto de las instituciones jurídico-políticas de las que gozan los representantes de la sociedad en el ejercicio del poder político, en estricto sentido de aquellas creadas constitucionalmente para el Poder Parlamentario y que se a saber son: la inviolabilidad, la inmunidad y el aforamiento. Instituciones de protección nacidas en aras del principio de división de poderes dentro de un Estado Constitucional Democrático de Derecho. Estudio que se realiza en busca de elementos que nutran y justifiquen el discurso de la necesidad de preservación de estas garantías constitucionales en la construcción constitucional en esta forma de Estado, dentro del cual se establezcan como elementos de control del poder, como contenidos materiales de la Constitución. Tema de relevancia en la discusión sobre los límites del poder político en la democracia representativa. En él se hace una presentación histórica del nacimiento de estas instituciones jurídicas dentro del medievo inglés y el constitucionalismo liberal de la Francia revolucionaria, hasta llegar a la percepción actual del constitucionalismo ibérico y mexicano respectivamente. De igual forma se abordan las formas de concepción normativa y práctica de estas instituciones de protección estatal y en específico de la recaída en la aplicación del aforamiento parlamentario.

Published: March 2019

Los Profesores Lucio Pegoraro y Angelo Rinella son autores de una rica y abundante bibliografía sobre Derecho Público Comparado (en España esta denominación responde a lo que conocemos como Derecho Constitucional Comparado), bastante bien difundida en España, pero que porque “la lechuza de Minerva levanta el vuelo al atardecer” (Hegel), sólo ahora empieza a ser asimilada por los académicos españoles y latinoamericanos. Aunque los constitucionalistas españoles siempre mostraron interés por la comparación, incluso durante el franquismo (piénsese, por ejemplo, en Pablo Lucas Verdú), los trabajos de muchos de ellos presentaban lagunas en cuanto al método: especialmente, como señala Pegoraro en varias de sus obras, Manuel García Pelayo, cuyo Manual de Derecho Constitucional Comparado es una excelente obra de Teoría de la Constitución, donde además se aborda con brillantez los aspectos más relevantes del Derecho Constitucional de varios Estados, pero donde no se realiza, en el sentido propio del término, una verdadera comparación.

olgusu çalışma yaşamında önemli bir sorun teşkil etmektedir. Sözlük karşılığı
bezdiri olan mobbing; duygusal şiddet duygusal linç, psikolojik terör, kuşatma,
taciz, anlamlarına gelmektedir. İnsan haklarının da ihlal edilmiş hali olan
mobbing çalışanların güvence olarak göreceği bir yasal düzenleme olmadığı için

MACKAY FUNCTIONS IN SPACES OF HIGHER LEVELS
Authors: Voskresenskaya G. V.
Published: March 2019

In the article we prove structure theorems for spaces of cusps forms with the levels that are divisible by the minimal levels for MakKay functions. There are 28 etaproducts with multiplicative Fourier coeffi- cients. They are called MacKay functions. Let f(z) be such function. It belongs to the space Sl(0(N), ) for a minimal level N. In each space of the level N there is the exact cutting by the function f(z). Also the function f(z) is a cusp form for multiple levels. In this case the exact cutting doesnt take place and the additional spaces exist. In this article we find the conditions for the divisor of functions that are divisible by f(z) and we study the structure of additional spaces. Dimensions of the spaces are calculated by the Cohen Oesterle formula, the orders in cusps are calculated by the Biagioli formula.

Valor terapéutico y precio de los nuevos fármacos comercializados en Argentina: ¿valen lo que cuestan?
Authors: Cañás Martín , Buschiazzo Héctor Omar , Urtasun Martín Alejandro
Published: March 2019

En Argentina, los nuevos medicamentos pueden ser autorizados presentando el certificado de aprobación en al menos uno de los 15 países considerados de alta vigilancia sanitaria, sin necesidad de realizar una evaluación propia de eficacia, seguridad o valor terapéutico agregado por el nuevo producto. En este artículo, evaluamos los nuevos medicamentos comercializados en Argentina en el año 2016, utilizando diferentes enfoques: su aprobación por otras agencias reguladoras, demostración de eficacia en ensayos clínicos aleatorizados, tipo de desenlaces estudiados, calificación del valor terapéutico agregado por medio de dos escalas reconocidas y el precio de venta al público. Se concluye que, como reflejo de lo que ocurre en los países desarrollados, los nuevos medicamentos ingresan con precios exorbitantes, pero la mayoría no representa un avance terapéutico significativo. El resultado es un aumento de riesgos para los pacientes y una sobrecarga para los sistemas de financiación públicos y privados.
Democracia pragmática vis à vis democracia substancial: um diálogo entre Richard Posner e Ronald Dworkin
Authors: Verbicaro Loiane Prado , Ferreira Valeska Dayanne Pinto
Published: March 2019

O artigo, por intermédio de pesquisa bibliográfica de abordagem qualitativa, propõe-se a analisar concepções dissonantes de democracia. Por um lado, o arranjo institucional pragmático, que constrói um modelo de democracia baseado na conceituação proposta por Joseph Schumpeter, segundo a qual a democracia é um método para tomada de decisões políticas. Incorporando traços desse modelo, Richard Posner converge para uma noção política sem valor intrínseco, tratando-se somente de um engenho para escolha de governantes. De outro, uma estrutura democrática e substancial, que propõe-se à proteção de direitos individuais, garantia de liberdade, igualdade e dignidade. Neste modelo substancial, um debate autêntico e uma concepção coparticipativa são indispensáveis à noção de democracia.
Mechanizmy kontrolujące strukturę chromatyny
Authors: Sacharowski Sebastian P. , Sarnowski Tomasz J.
Published: March 2019

Genomic DNA is highly packaged in eukaryotic cells and occurs in the form of nucleoprotein complex called chromatin. Although high DNA compaction allows to store large amount of genomic information in the cell nuclei, it also restricts the access to DNA regulatory sequences. Therefore, to overcome this issue, chromatin must be subjected to various alterations which are dependent on few interrelated factors: DNA modification, histones variants and modifications, ncRNA, chromatin remodeling complexes and chromatin architecture in nuclei. They allow to multilayer regulation of fragile balance between transcriptionally active euchromatin and inactive heterochromatin. The newest research describe new chromatin elements, e.g. half nucleosomes, bivalent chromatin marker and pointed to few intermediate states between euchromatin and heterochromatin. Variety and remarkable amount of chromatin modifications require existence of multiprotein complexes reading, editing and integrating genomic information. Some of them are able to remodel nucleosomes in order to control access to particular DNA sequence. Due to the complexity of chromatin structure regulation studies describing these mechanisms are fundamental to understanding the eukaryotes life.

Sirtuins are â in mammals - a family of seven enzymes (sirtuin 1-7) involved in post-translational modification of proteins (mainly deacetylation, but also: polyADP-ribosylation, demalonylation or lipoamidation), and thus â in the regulation of many metabolic processes. The activity of all sirtuins depends on the availability of NAD+. However, the function of individual isoforms is different, even mutually antagonistic. In this article the role of sirtuins in the regulation of glucose and lipid metabolism and in DNA repair mechanisms is described in detail. The significance of these enzymes in diseases pathogenesis, with particular emphasis on diabetes and cancer, is also discussed, indicating the possible therapeutic use of sirtuin activity modulators.
Supresja odporności podstawowej typu PTI przez syntetyzowane w fitopatogenach białka efektorowe wprowadzane do wnętrza komórek infekowanej rośliny
Authors: Hetmann Anna , Kowalczyk Stanisław

Plant immunity is constituted by multilayered system involving two intertwined lines of defence: a first level of immunity termed PAMPâtriggered immunity (PTI) or basal resistance, and a second layer of plant defence, called effector-triggered immunity (ETI). The second lineof defence depends on the ability of the plant to recognize phytopathogen-synthesized effector proteins delivered into host plant cells. The effector proteins employ common as well as pathogen-specific strategies to disturb plant immunity and to promote pathogen survival and favor their multiplication. They target pattern-recognition receptors (PRRs) and key components in the PTI signaling pathways, as well as, they interfere with many cellular processes including vesicle transport, cytoskeleton reorganization, proteasome-dependent protein degradation, phytohormone biosynthesis and signaling, and gene expression. This results in effector-triggered susceptibility (ETS). However, in some cases, pathogen effectors are recognized by plant intracellular immune receptors NB-LRR/NLR that identify effector proteins. Conformational changes in the NB-LRR/NLR immune receptors accompanying the recognition of the effector proteins activate intracellular signaling pathways initiating a whole range of defence responses that form the second line of local defence.
Aproximaciones de una metodología semiótica para el análisis de la educación en Colombia: un aporte al desarrollo de la edusemiótica
Authors: Rodríguez Jerez Sergio Alejandro
Published: March 2019

La aplicabilidad metodológica de la semiótica es una de las grandes preocupaciones y retos de los semiólogos contemporáneos. Por este motivo, el presente artículo tiene como objetivo diseñar un sistema metodológico estructural para el estudio de la educación desde un enfoque semiótico. Esta propuesta es el resultado del trabajo investigativo realizado por la Red de Lectura y Escritura para la Educación Superior (REDLESS) de la Asociación Colombiana de Universidades (ASCUN), mediante el cual se analizó la significación otorgada al concepto de calidad en Colombia. En síntesis el trabajo muestra cómo se puede aplicar la metodología semiótica en la educación, brindando un valioso aporte al desarrollo de la rama edusemiótica presentada en el 12vo Congreso Mundial de Semiótica en Bulgaria (2014).
Neoliberalismo e Educação Ambiental: uma leitura crítica sobre as relações público-privadas entre escolas e o agronegócio
Authors: Borghi Mendes Carolina , Liria Biscalquini Talamoni Jandira
Published: March 2019

Defendemos a Educação Ambiental (EA) como um processo educativo que deve ser desenvolvido na educação escolar, comprometido com formação de indivíduos críticos que busquem a construção de uma sociedade ecologicamente equilibrada e socialmente justa. No presente estudo nos propomos discuti-la considerando os pressupostos neoliberais que, por razões concretas, delinearam o cenário educacional, possibilitando e fortalecendo as relações público-privadas entre as escolas públicas e o setor empresarial, em especial o do agronegócio. A escolha dessa análise se justifica, primeiramente, pela defesa de que o papel da educação escolar é o de possibilitar às classes trabalhadoras o acesso ao conhecimento sistematizado e, nesse sentido, é um ato político que não pode ser descaracterizado por ações ideológicas que valorizam os interesses do capital, nem mesmo na EA; em segundo lugar, por entendermos que o agronegócio tem grande relevância político-econômica e cultural no Brasil, com características históricas de degradação socioambiental e com forte inserção nas escolas públicas na região de Ribeirão Preto, por estratégia da Associação Brasileira do Agronegócio (ABAG). Temos como fundamento o Materialismo Histórico-Dialético, a favor da Educação Ambiental Crítica, em diálogo com os pressupostos da Pedagogia Histórico-Crítica. A discussão se concentra na inserção do setor privado em questão nas escolas públicas pela EA em decorrência do neoliberalismo, nas interferências geradas por esse processo à educação escolar pública e na necessidade de enfrentarmos as parcerias público-privadas.
Wykonywanie uprawnień komplementariusza w spółce komandytowej przez jego prokurenta glosa do postanowienia Sądu Najwyższego z dnia 16 czerwca 2016 r., V CZ 26/16
Authors: Zbrojewski Adrian
Published: March 2019

Glosa odnosi się do orzeczenia Sądu Najwyższego, które zezwala na reprezentowanie spółki komandytowej przez prokurenta jej komplementariusza, będącego osobą prawną, nawet w sytuacji niepełnego obsadzenia jego zarządu. Autor, zgadzając się z powyższym stanowiskiem, w sposób krytyczny odnosi się do uzasadnienia orzeczenia. W szczególności w glosie wskazano na brak przeprowadzenia przez Sąd Najwyższy analizy pojęcia „czynności związanych z prowadzeniem przedsiębiorstwa”, które determinuje zakres umocowania prokurenta. W konsekwencji w glosie podjęto próbę jego zdefiniowania, która ostatecznie doprowadziła autora do przekonania, że zakres prokury obejmuje wykonywanie uprawnień komplementariusza w spółce komandytowej. Glosa rozważa także kwestię nieważności postępowania w kontekście wadliwości reprezentacji jego stron.
Shakespeare in Digital Games and Virtual Worlds
Authors: Timplalexi Eleni
Published: March 2019

Shakespeare’s plays have long flirted with using various artistic and medial forms other than theatre, such as cinema, music, visual arts, television, comics, animation and, lately, digital games and virtual worlds. Especially in the 20th and 21st century, a fascination with Shakespeare both as a historical and theatrical figure and as a playwright has become evident in screen based media (cinema, television and video), ranging from “faithful,” almost documented performances of his plays to free style adaptations or vague film references. Digital games and virtual worlds carry on this tradition of the transmedial journey of Shakespeare’s plays to screen based media but top it up with new forms of interaction and performativity. For the first time in the history of mankind everyone can enjoy firsthand from his armchair and for free the experience of taking part in a play by the Bard by entering a virtual world as if it was a stage and by assuming roles through avatars. The article attempts first to introduce the reader to the deeper needs that gave rise to animation, a fundamental aspect of digital gaming and virtual worlds. It then tries to illuminate the various facets of digital performance and gaming, especially in relation to Shakespeare-themed and inspired digital games and virtual worlds, by putting forward some axes of classification. Finally, it both suggests some ideas that may be of use in rendering the Shakespeare gaming experience more “complete” and “theatrical” and ends by acknowledging the immense potential for the exploration of theatricality and performativity in digital games and virtual worlds.
Decentering the Bard: The Localization of "King Lear" in Egyptian TV Drama "Dahsha"
Authors: Selim Yasser Fouad
Published: March 2019

Dahsha [Bewilderment] is an Egyptian TV series written by scriptwriter Abdelrahim Kamal and adapted from Shakespeare’s King Lear. The TV drama locates Al Basel Hamad Al Basha, Lear’s counterpart, in Upper Egypt and follows a localized version of the king’s tragedy starting from the division of his lands between his two wicked daughters and the disinheritance of his sincere daughter till his downfall. This study examines the relationship between Dahsha and King Lear and investigates the position of the Bard when contextualized in other cultures, revisited in other locales, and retold in other languages. It raises many questions about Shakespeare’s proximity to the transcultural/transnational adaptations of his plays. Does Shakespeare’s discourse limit the interpretation of the adapted works or does it promote intercultural conversations between the varying worldviews? Where is the Bard positioned when contextualized in other cultures, revisited in other locales, and retold in other languages? Does he stand in the center or at the margin? The study attempts to answer these questions and to read the Egyptian localization of King Lear as an independent work that transposes Shakespeare from a central dominant element into a periphery that remains visible in the background of the Upper Egyptian drama.

Published: March 2019

Ollution of atmospheric air in an industrial city saturated with toxic substances leads to the gain in diseases of the respiratory system. With the aim to identify early pathologies, adolescents living in urbanized areas were examined. There were revealed desquamation, decay of epithelial cells of the nasal cavity and enhanced synthesis of the surfactant according to the condensate of exhaled air, which indicates to a non-specific defeat of the respiratory system by toxic agents. These studies can be used for the development of preventive measures and early detection of diseases caused by unfavorable environmental conditions.

On the basis of the system review, the relevance of the problem of the chloroform content in the drinking water of centralized drinking-water supply systems in the Perm Territory is confirmed. The comparative characteristic with the average Russian indices is presented. Insufficient volume of information containing data on the impact of the oral intake of chloroform on the blood system was established. There are presented results of the research content of chloroform in water samples from centralized drinking water supply in the cities of Perm region, as well as in the blood of the child population aged from 3 to 13 years living in these areas and consuming water under investigation in the period from 2011 to 2015. A long-term dynamics of the content of chloroform, contained in samples of drinking water and in bio-environments is described. A mathematical simulation of the dependence of the chloroform content in the blood as an exposure marker on the concentration of chloroform in water was carried out. As a result of the analysis of the prevalence rate of diseases of the blood system, hematopoietic organs and certain disorders involving the immune mechanism in the child population, there was established the relevance of differences between the territories of Permsky Krai with surface and underground water supply. The dynamics of the chloroform content in water and morbidity according to the class of blood diseases, hematopoietic organs and certain disorders involving the immune mechanism is presented and described. The association between the exposure to the oral intake of chloroform with drinking water with a morbidity on the class of diseases of the blood system was established on the basis of constructing a mathematical model. The conclusion about the legitimacy of information on the effect of the oral intake of chloroform on the blood system, hematopoietic organs and certain disorders involving the immune mechanism is presented.
