OCUPAÇÃO DO ESPAÇO URBANO E EVOLUÇÃO LEGAL DA APP’S DOS CURSOS D’ÁGUA DA LEI Nº 12.651/2012: Reflexões temporais na cidade de Boa Vista – Roraima
Authors: Oliveira Júnior Zedequias De , Veras Antônio Tolrino de Rezende , Galdino Lúcio Keury Almeida
Published: July 2018

Uma forma de avaliar a dinâmica da ocupação espacial e seus reflexos negativos urbanos é pela percepção do antropismo nas áreas de preservação permanente dos cursos d’água. Este o parâmetro de abordagem que se pretende demonstrar voltado para a realidade do município amazônico de Boa Vista, capital do estado de Roraima. Utilizou-se, para tanto, o método científico dedutivo por meio de recursos lógico-discursivos com levantamento, revisão e pesquisa bibliográfica e legal que permitiu esquadrinhar as causas, implicações no cotidiano urbano e consequências de ordem pública, ambiental e urbanística das referidas ocupações antrópicas, considerando dados doCenso de 2010 e a entrada em vigor do atual terceiro Código Florestal brasileiro, Lei nº 12.651/2012. Partindo destas premissas, buscou-se esquadrinhar a intervenção nestas frágeis localidades, desde a formação do primeiro núcleo urbano até o presente, e a forma como ocorreu o crescimento populacional ao longo de sua história. A pesquisa exploratória e o cotejo analítico dos principais fatores envolvidos possibilitou a efetivação de diversas reflexões capazes de contribuir para uma discussão aberta e especializada dos problemas correlatos e servir como indicativo para soluções mais abalizadas que deveriam ser implementadas para minimizar o aumento do passivo ambiental nas APP´s ripárias.
A exclusão social do idoso no ambiente urbano
Authors: Fornasier Mateus De Oliveira , Leite Flavia Piva Almeida
Published: July 2018

Este artigo estuda a exclusão social do idoso do ambiente urbano – principalmente no que tange à obliteração dos seus direitos de ir e vir e de participar da vida em comunidade. Apresenta fatores histórico-filosóficos e científicos acerca de quem é o idoso e de como este é considerado excluído da sociedade. Também observa a exclusão do idoso do ambiente urbano, com dados científicos acerca de fatores de exclusão no mundo e no Brasil, exemplificando-se, também, de que forma o prejuízo na mobilidade urbana da terceira idade é um fator incrementador de sua exclusão decorrente do próprio envelhecimento biológico. Nesta senda, conclui que a urbanização deve ser entendida como ocorrência diretamente ligada à globalização: atinge-se não apenas o espaço e as interações urbanas, mas também se organizam as relações sociais no campo em direção ao centro urbano. Ademais, os sistemas funcionais pressupõem a inclusão de todos os seres humanos, mas de fato, excluem pessoas que não preenchem seus requisitos, e um tipo de exclusão serve de fundamento para os demais. Por fim não é a busca por um responsável pela exclusão, mas sim, a análise de que se trata de um complexo de responsabilidades, é o que deve embasar políticas públicas de inclusão da pessoa idosa no ambiente urbano. Metodologia: sistêmico-construtivista.
O ambiente como bem jurídico: a contribuição da análise econômica ao debate no direito brasileiro
Authors: Mota Maurício Jorge Pereira da , Gama Guilherme Calmon Nogueira da , Cardoso Patricia Silva
Published: July 2018

A tensão existente entre desenvolvimento econômico e preservação ambiental provoca acalorados debates no cenário contemporâneo, marcado por um contexto de contínua expansão do mercado global. O conflito exige uma profunda reflexão, direcionada para a busca de mecanismos que promovam uma conciliação mínima entre os dois vetores. A União Europeia define a questão ambiental como um dos vértices de sua política econômica e pretende conciliar a proteção ao meio-ambiente com a sua posição competitiva no mercado mundial. Insere-se nesta linha o sétimo programa de ação ambiental da UE, que  prevê como um de seus objetivos prioritários a abordagem correta das externalidades ambientais. Com o intuito de promover uma reflexão maior sobre o tema, serão descritos alguns modelos de proteção ambiental adotados por Estados-nacionais e seus fundamentos jurídicos. Apesar das preocupações internacionais ocuparem o discurso atual, é importante verificar em que medida as localidades incorporam tais diretrizes globais e quais são os obstáculos encontrados na efetividade da proteção ambiental. Diante do apontado, cresce a importância dos instrumentos econômicos na tutela do meio ambiente, em especial aqueles que desestimulam a poluição e premiam a conservação. Por tal motivo, serão também descritos os instrumentos econômicos de tutela ambiental existentes no Brasil, com especial ênfase nos mecanismos de compensação das externalidades negativas em empreendimentos causadores de impactos ambientais. O estudo da experiência brasileira pode contribuir eficazmente para a consideração adequada dos fatores externos ambientais e otimizar os mecanismos de externalidades negativas existentes na UE.

Spatial Heterogeneity of Soil Respiration Response to Precipitation Pulse in a Temperate Mixed Forest in Central China
Authors: Liu Yanchun , Shang Qing , Wang Zhongwei , Zhang Kesheng
Published: July 2018

Water availability is one of the fundamental drivers for biological activities and terrestrial carbon cycling. Although the response of soil respiration to precipitation has been well documented in arid and semiarid ecosystems, our understanding of its pattern in forests is rather limited. This study was conducted to examine the difference of precipitation effect on soil respiration under different canopy conditions in a temperate coniferous (Pinus armandii Franch) and broadleaved (Quercus aliena var. acuteserrata) mixed forest in Central China. The results showed that precipitation significantly reduced soil temperature, but increased soil volumetric water content and soil respiration (6.0%-35.3%). Precipitation caused a greater increment in soil respiration beneath the canopy of broadleaved trees (24.2%) than that beneath coniferous ones (13.5%). Precipitation-induced increase in soil respiration was consistently lower beneath the canopy of small size classes (7.1%-32.6%) than large size classes (9.5%-33.3%). Mean soil respiration of forest gaps increased 22.4% following precipitations. Our study highlights the positive response of soil respiration to precipitation pulses in water-unlimited ecosystems. The findings suggest that the spatial heterogeneity of soil respiration to precipitation pulse under different canopy conditions should be emphasized while assessing terrestrial carbon cycling and its feedback to climate change.
Preliminary Survey on The Termite Mounds, Their Interior Geometrics and The Termite Prevention from Infrastructural Construction at New Site of Ndola International Airport in Zambia

Published: July 2018

An ecological study was conducted on termites located at the new site of Ndola International Airport in Zambia. The aim of this study was: (a) to assess the distribution pattern of different sizes of termite mounds located at the site, (b) to investigate the interior geometrics of termite mounds, (c) to determine the colony sizes of termites per each mound found at the site and (d) to provide technical expertise on the different termite preventive methods used on new buildings.

Methods
Using an aero-drone fitted with a camera, aerial surveys were conducted to capture and evaluate the spread of differently sized mounds at the site. Mathematical models were used to calculate the volume and number of nests contained in each mound. The colony sizes were captured and recorded per each mound.

Analysis
Multivariate statistical analyses were performed using SPSS, to compute a two way ANOVA table for comparison of p-values involving the colony sizes and the volumes of nests for small and big mounds. The ratios affecting these volumes were also calculated.

Results
The total of 1,880 termite mounds was captured spreading at an average of 14 mounds/ 1km2. Results further showed that 65% of total mounds were actively housing termites while 32% were virtually deserted. The 3% balance of mounds were occupied by rodents, ants and snakes, respectively. Progression on the volume of nests in bigger and smaller mounds, significantly tallied with the size of mound at p < 0.0121 and p < 0.0346, respectively. Similarly, the colony size of termites in small and larger mounds was also significant at p < 0.002 and p < 0.001, respectively. The nest volume ratios of small, medium and larger mounds were also markedly increasing with the size of mound at 1:8.7-small, 1:32.8 medium and 1:1, 098.6-large, respectively.

Conclusion
Not every existing termite mound is occupied by termites; the size of nest was directly related to the size of mound; the size of colony concurrently increased with that of the volume of nest. This study unravels some intriguing and conflicting suggestions that smaller mounds can still have larger colonies underground and vice versa. Furthermore, this study is the first in Zambia to combine the concepts of termite habitat geometrics and infrastructural protection.

En el presente trabajo se demuestra, siguiendo a Levinas, que la ética, entendida como la relación intersubjetiva entre sujetos absolutamente separados, se instaura a partir de acontecimientos concretos que determinan la existencia histórica del hombre, pero revistiendo éstos la particularidad de ser acontecimientos que escapan al orden ontològico. Antes bien, remiten a un más allá, a un fuera-de la ontologia significando ante todo de manera ética, es decir de otro modo que ser.
Reducción fenomenológica y figuras de la excedencia
Authors: Walton Roberto J.
Published: July 2018

Luego de Husserl y Heidegger, la fenomenología ha intentado llevar la reducción más allá de la referencia de los objetos a las operaciones efectuadas por la conciencia o de los entes al ser. En primer lugar, un nuevo nivel de reducción se manifiesta en la reducción radical propuesta por M. Henry para retroceder del aparecer al aparecer del aparecer, y conduce al descubrimiento de una dimensión en que no hay horizontes que puedan ser plenificados porque impera la sobreabundancia del la vida. En segundo lugar, según H. Rombach, los fenómenos descritos en los dos primeros niveles no son otra cosa que epifenómenos y tienen que ser explicados en términos de estructuras que emergen en un desarrollo creador. La realidad produce algo a partir de sí misma, y esta contribución debe ser aprovechada a fin de alcanzar más de lo anticipado en nuestros proyectos. En tercer lugar, J.-L. Marion presenta una teoría sobre los fenómenos saturados a fin de dar cuenta de aquellos casos que exceden los límites que les han sido delineados en las intenciones significativas vacías porque muestran una demasía de intuición. Las tres tendencias conducen respectivamente a una fenomenalidad originaria, a un estallido del fenómeno y a una saturación del fenómeno. El artículo sostiene que tienden a converger porque vinculan el tercer nivel de la fenomenología con una reflexión en torno de la dualidad entre lo que aparece y su aparecer, y que, al hacerlo, ponen de manifiesto una excedencia respecto de tres aspectos distintos de la dualidad, esto es, el aparecer en cuanto tal, la condición general de lo que aparece o la aparición de algunos fenómenos preeminentes. Finalmente, se indican algunas anticipaciones de estas tendencias en la fenomenología trascendental de Husserl.
La gramática de las pasiones en la era de la igualdad
Authors: González de Requena Farré Juan Antonio
Published: July 2018

El pathos de la democracia moderna ha sido descrito de diversos modos, aunque comúnmente en un sentido unívoco. A veces, se dice que la era de la igualdad exhibe una reflexividad y un autocontrol desapasionados; otras veces, la modernidad es retratada como un proceso de exacerbación de los deseos, o como una gran transformación de las pasiones en intereses razonables. Además, las pasiones democráticas son vistas frecuentemente como pequeños sentimientos domésticos, alienados de la esfera pública, gestionados en una intimidad clausurada, y sujetos a una administración tutelar. Tocqueville —quien fue un testigo único y privilegiado de la transición del pathos aristocrático a las pasiones democráticas— nos suministra una sutil interpretación de los variados matices y los complejos vínculos que configuran los afectos modernos. En este artículo, analizamos la prognosis de Tocqueville acerca del curso del pathos democrático, pero también prestamos atención a sus temores relativos a una gestión emocional tutelar.
De la vida, la muerte y la resistencia en las investigaciones de Michel Foucault sobre biopolítica
Authors: López Cristina
Published: July 2018

A pesar de los avances efectuados en la comprensión de los alcances y los límites de las investigaciones de Michel Foucault sobre el dispositivo biopolítico de ejercicio del poder, aún subsisten ciertas dudas respecto del nexo de las mismas con la genealogía del liberalismo en que parecen desembocar. En este contexto, su tratamiento de las cuestiones de la vida, la muerte y la resistencia se vuelve problemático. Intentando esclarecer estas cuestiones, en este artículo se intentará dar cuenta de los motivos que orientan los análisis del autor hacia la cuestión de la gubernamentalidad liberal y del sesgo que en este marco adquiere su consideración de la biopolítica como un poder caracterizado por “hacer vivir y dejar morir”.
Esencia y modalidad: Husserl y Kripke
Authors: Romano Claude , Greve María Cristina
Published: July 2018

En este trabajo se analizan las nociones de esencia en Husserl y Kripke marcando sus relaciones y diferencias. Husserl excluye una definición modal de la esencia, considerando que las necesidades incondicionadas tienen su fuente en las esencias y no recíprocamente. Por su parte, la concepción de Kripke obliga a repensar nociones supuestamente evidentes sostenidas por Husserl, como la equivalencia a priori/necesario, a posteriori/contingente, así como los lazos entre concebibilidad y posibilidad. Tomando distancia respecto de la posición de Husserl, se rechaza aquí la variación eidética como método único y se enfatiza finalmente el valor de la discusión razonada.

Uniaxial Tension of a Filament-wound Composite Tube at Low Temperature
Authors: Szabó Gyula , Váradi Károly
Published: July 2018

The aim of this article is to model mechanical behavior of a filament-wound, rubber-based composite tube subjected to uniaxial tension at low temperature by test experiments and FE simulations. Uniaxial tensile tests at sub-zero temperature (-40 °C) have been carried out on standard test specimens and on hose pieces. furthermore, a uniaxial tensile test has been performed on a hose piece at room temperature as a reference experiment. Reinforcement layers of the composite tube are modeled as transversely isotropic, whereas elastomer liners are described by 2 parameter Mooney-Rivlin hyperelastic material model. Temperature-dependence of elastic constants of composite layers is attributed to the temperature-dependence of rubber, so uniaxial tensile tests on standard test specimens needed to be carried out for determining material properties of rubber at sub-zero temperature (-40°C).

Force-displacement results of FE models and experiments of standard test specimen and hose piece show good agreement. Likewise, force-displacement curves of reference experiment (carried out at room temperature) and its related FE simulation are in good agreement with each other. Slope of force-displacement curves of hose piece at -40 °C is nearly 3.4 times the slope of force-displacement curves of hose piece at room temperature.
Comparison of Effects of Different Antidotes on Tabun-Induced Cognitive Impairment in Rats Using Water Maze
Authors: Kunešová Gabriela , Kassa Jiří
Published: July 2018

In the past, scientists focused on the development of antidotes (mainly anticholinergics in combination with reactivators of inhibited acetylcholinesterase – oximes) to increase the number of surviving nerve agent-intoxicated individuals. Recently, they are interested in antidotes able not only to protect nerve agent-poisoned men from lethal toxic effects but also to improve their life quality by improvement of their central cognitive functions. In our study, the water maze was used to measure spatial working learning and memory in the case of tabun-induced cognitive impairment in albino Wistar rats. Antidotal treatment consisted of atropine alone or a combination of atropine with an oxime (obidoxime, trimedoxime or oxime HI-6). Our results suggest that atropine alone is not sufficient as a treatment for saving cognitive functions impaired by tabun. On the other hand, the addition of oxime to atropine contributes to improvement of cognitive performance in tabun-poisoned rats regardless of type of oxime.
Interpersonal discussions and immigration attitudes
Authors: Kalogeropoulos Antonis , Hopmann David Nicolas
Published: July 2018

The antecedents of immigration attitudes have been extensively examined in academic research, in particular, with respect to media use and personal contact with immigrants. Research on the role of interpersonal discussions about the issue of immigration has been scarce, however. Results from a two-wave panel survey show that individuals holding unfavorable attitudes towards immigration engaged more often in interpersonal communication about immigration, which colored the overall effect of engaging in such discussions. The implications of these results are discussed in the concluding section.
The Futurism of Hip Hop: Space, Electro and Science Fiction in Rap
Authors: de Paor-Evans Adam
Published: July 2018

In the early 1980s, an important facet of hip hop culture developed a style of music known as electro-rap, much of which carries narratives linked to science fiction, fantasy and references to arcade games and comic books. The aim of this article is to build a critical inquiry into the cultural and sociopolitical presence of these ideas as drivers for the productions of electro-rap, and subsequently through artists from Newcleus to Strange U seeks to interrogate the value of science fiction from the 1980s to the 2000s, evaluating the validity of science fiction’s place in the future of hip hop. Theoretically underpinned by the emerging theories associated with Afrofuturism and Paul Virilio’s dromosphere and picnolepsy concepts, the article reconsiders time and spatial context as a palimpsest whereby the saturation of digitalisation becomes both accelerator and obstacle and proposes a thirdspace-dromology. In conclusion, the article repositions contemporary hip hop and unearths the realities of science fiction and closes by offering specific directions for both the future within and the future of hip hop culture and its potential impact on future society
A single domain antibody against the Cys- and His-rich domain of PCSK9 and evolocumab exhibit different inhibition mechanisms in humanized PCSK9 mice

Published: July 2018

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secreted protein that binds and escorts the low density lipoprotein receptor (LDLR) into the lysosomal degradation pathway. Prescribed monoclonal antibodies (mAbs) against PCSK9 prevent its binding to the LDLR, and result in ~60% lower LDL cholesterol (LDLc) levels. Although efficient, mAbs are expensive. Hence other PCSK9 inhibitors are needed. For screening purpose, we developed C57BL/6J mice expressing the human PCSK9 gene under the control of its own promoter, but lacking endogenous mouse PCSK9. All lines recapitulate the endogenous PCSK9 expression pattern. The Tg2 line that expresses physiological levels of human PCSK9 (hPCSK9) was selected to characterize the inhibitory properties of a previously reported single domain antibody (sdAb), PKF8-mFc, which binds the C-terminal domain of PCSK9. Upon intraveinous injection of 10 mg/kg, PKF8-mFc and the mAb evolocumab neutralized ~50% and 100% of the hPCSK9 impact on total cholesterol (TC) levels, respectively, but PKF8-mFc had a more sustained effect. PKF8-mFc barely affected hPCSK9 levels, whereas evolocumab promoted a 4-fold increase 3 days post-injection, suggesting very different inhibitory mechanisms. The present study also shows that the new transgenic mice are well suited to screen a variety of hPCSK9 inhibitors.
The use of variance reduction, relative error and bias in testing the performance of M/G/1 retrial queues estimators in Monte Carlo simulation
Authors: Tamiti Kenza , Ourbih-Tari Megdouda , Aloui Abdelouhab , Idjis Khelidja
Published: July 2018

This paper deals with Monte Carlo simulation and focuses on the use of the concepts of variance reduction,
relative error and bias in testing the performance of stationary M/G/1 retrial queues estimators using either Random Sampling (RS) or Refined Descriptive Sampling (RDS) to generate input samples. For this purpose, a software under Linux system
using the C compiler was designed and realized providing the performance measures of such system and the statistical concepts of bias, relative error and accuracy using both sampling methods. As a conclusion, it has been shown that the performance of stationary M/G/1 retrial queues estimators is better using RDS than RS and sometimes by a substantial variance reduction factor.

We report a simple approach for synthesizing monodispersed, crystalline and size-tunable tin sulfide nanoparticles for environment friendly next generation solar cell applications. Both SnS and SnS2nanoparticles could be a potential nanomaterial for solar cells. The structural, morphological, thermal and optical properties were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), diffuse reflectance spectroscopy (DRS) and Fourier transform infrared spectroscopy (FT-IR). The XRD spectra revealed hexagonal and orthorhombic phases of SnS and SnS2 nanoparticles, respectively, where the grains size ranged from 11 nm to 30 nm. The weight percentage as a function of temperature was determined using TGA analysis. Functional groups were observed by FT-IR. The energy bandgap was determined as 1.41 eV showing usefulness of the nanoparticles in next generation environmental friendly solar energy applications.
Social Class, Interactional Pragmatics and the Likely Lads
Authors: Ponton D. M.
Published: July 2018

Long exposed to the democraticising effects of modernity, Britain's class structure supposedly collapsed during the 1990s (Turner 2013), though against this contention there is ample evidence to suggest that its essential contours are unaltered, and that the classless society is itself a myth (Marshall et al 1988). This paper explores an earlier period, in Britain's not too distant past, when the labels, 'working class' and 'middle class' were less controversial. The BBC's sit-com 'Whatever happened to the likely lads?' (Clement and La Frenais), from the early 1970s, was one of its most successful ever, enjoying both public support and critical acclaim. The show follows the lives of Bob Ferris and Terry Collier, two working class school-friends from the north-east who, after a period of separation, find each other again as they start out in life. While Bob is aspirational, attempting to achieve his goals of social progress through work, further education and marriage, Terry pursues the same lifestyle, viewing his friend's progress in terms of class betrayal. An episode from the series will be explored using a pragmatic-dialogic approach (Kecskes 2016), to suggest that the invisible framework of class needs to be invoked in order to make sense of the dialogue
A note on the characterizations of the distributions of the condition numbers of real Gaussian matrices
Authors: Shakil M. , Ahsanullah M.
Published: July 2018

Many researchers and authors have studied the distributions of the condition numbers of real Gaussian matrices, which appear in many fields of pure and applied sciences, such as, probability, statistics, multivariate statistics, linear algebra, operator algebra theory, actuarial science, physics, wireless communications, and polarimetric synthetic aperture radar (PolSAR). Motivated by this, in this paper, we first present several new distributional properties of the distributions of the condition numbers of real Gaussian matrices. Since it is important to know the percentage points of a given distribution for any statistical application, we have also computed percentiles of the said distributions of the condition numbers. Before a particular probability distribution model is applied to fit the real world data, it is necessary to confirm whether the given continuous probability distribution satisfies the underlying requirements by its characterizations. Also, the truncated distributions arise in practical statisticswhere the ability of record observations is limited to a given threshold or within a specified range. In view of these facts, some characterizations by truncated first moment are also presented. We hope that the findings of this paper will be quite useful to the researchers in various fields of pure and applied sciences as stated above.

Construction of Two-Ququart Quantum Entanglement by Using Magnetic Resonance Selective Pulse Sequences
Authors: Karakaş Mikail Doğuş , Gençten Azmi
Published: July 2018

A d-dimensional unit of information in quantum computing is called a qudit. For d = 4 there exist four magnetic quantum numbers of spin-3/2. These four levels can be called ququarts. Then, for the SI (S = 3/2, I = 3/2) spin system, 16 two-ququart states are obtained. In this study, first, two-ququart entangled states are constructed by using matrix representation of Hadamard and CNOT logic gates. Two-ququart entangled states are also constructed by using magnetic resonance selective pulse sequences of Hadamard and CNOT logic gates. Then, a generalised expression is obtained for the transformation of two-qudit entangled states between each other. This expression is applied for two-ququart entangled states.
La construcción de identidad de estudiantes de inglés desde una perspectiva social y los efectos en su aprendizaje
Authors: Collazos Moná Maritza , Gómez Rodríguez Luis Fernando
Published: July 2018

Este estudio de caso analizó cómo unos estudiantes de séptimo grado construyeron sus identidades como aprendices de inglés de un colegio público de Bogotá, Colombia. Se recogieron da-tos de los comportamientos e identidades de estos aprendices mediante notas de campo y entrevistas. También se reunieron opiniones de los estudiantes sobre su estatus social como aprendices de inglés, mediante un cuestionario y una entrevista. Estos datos fueron analizados a la luz de la teoría de Norton sobre identidad e inversión desde una perspectiva social. Los hallazgos indican que los estudiantes fueron renuentes a aprender inglés a causa de varios factores sociales, incluyendo su situación socioe-conómica, exigencias académicas y familiares y la imposición de relaciones de poder en el salón. Por lo tanto, crearon identidades estratégicas, inestables y contradictorias como aprendices de inglés para enfrentar dichos conflictos sociales, mientras que invirtieron poco en su proceso de aprendizaje.

Published: July 2018

En Colombia la gestión pública exige una transformación gerencial que le facilite al Estado implementar políticas focalizadas hacia el mejoramiento de la calidad de vida de los ciudadanos. La inexistencia de técnicas para la integración de la gestión en las entidades públicas impulsa la investigación que conlleva al diseño de una metodología para la integración de la gestión. Con un enfoque mixto y un alcance exploratorio secuencial, se establece la correlación existente entre los requisitos de las normas técnicas ISO 9001:2015, ISO 14001:2015 y los modelos normativos Decreto 1072 de 2015 (SG-SST), Decreto 943 de 2014 (MECI:2014) y Decreto 2482 de 2012 (MIPG:2012), obteniendo como resultado la matriz de correlación, producto de la revisión bibliográfica y la lectura crítica de las normas técnicas y los modelos normativos del Estado. A partir de esta matriz correlacional, se desarrollaron contenidos descriptivos, tomados como base para la construcción de encuestas de percepción, aplicando métodos estadísticos que sustentan el grado de correlación de los requisitos mediante el coeficiente de correlación de Spearman y la confiabilidad de los datos mediante el alfa de Cronbach, validando así el contenido de la matriz, que se constituye en referente orientador para la integración de sistemas de gestión en las entidades públicas.
Propuesta integral del sistema de gestión para las buenas prácticas de manufactura del sector cosmético colombiano
Authors: Rodriguez Labrador Sandra Milena
Published: July 2018

Actualmente los productores de cosméticos en Colombia se enfrentan con un entorno cada vez más competitivo y exigente; por un lado, para comercializar sus productos en territorio nacional y países de la Comunidad Andina de Naciones deben implementar y cumplir con lo establecido en la legislación, Decisión 516 del 2002 y Resolución 3773 del 2004, pero si desean llegar a países de la Comunidad Europea deben cumplir con las Buenas Prácticas de Manufactura (ISO 22716:2007). Los productores de cosméticos pueden certificar con la autoridad sanitaria, INVIMA, de forma voluntaria, las Buenas Prácticas de Manufactura a través de la Resolución 3774 del 2004 o con un ente certificador la ISO 22716:2007. Este es el panorama del sector de cosméticos en Colombia, que, como respuesta al entorno competitivo, implementan los sistemas de gestión y las normas legales de manera separada. Por lo tanto, un primer paso fue el diseño de una propuesta integral entre la legislación y las normas sobre las Buenas Prácticas de Manufactura del sector cosmético en Colombia; a través de la identificación, comparación, combinación, incorporación y fusión de los requisitos. El contenido de la propuesta fue evaluada por expertos y como resultado final se generó la guía de verificación.

Este trabajo busca reflexionar cómo los espacios escolares en ciertos contextos y momentos pueden convertirse en espacios sexuados. A través de las narrativas de tres jóvenes estudiantes universitarios, se hablará de cómo los espacios educativos pueden ser sitios que se utilicen para ejercer el placer erótico. Se abordarán algunos de los códigos que se generan alrededor de dichas prácticas y las formas de apropiación del espacio. También se reflexionará cómo, pese a la existencia de la heteronorma, los encuentros sexuales en las escuelas son un fenómeno que persiste y que trasciende algénero y la orientación sexual.

Published: July 2018

El presente artículo responde a la necesidad de hacer visibles los resultados del proyecto de investigación Ambientes que favorecen el desarrollo del sentido rítmico del estudiante de ciclo 3, realizado con la intención de analizar contextos y establecer parámetros para el diseño e implementación de un proyecto de aula exitoso. Con él se pretende garantizar el aprendizaje significativo de la música en un contexto de escuela pública: el colegio Nicolás Buenaventura. El proyecto parte de la necesidad de potenciar la habilidad rítmica dentro de la dinámica de clases formales de música, considerando el ritmo como eje formativo central. El trabajo es un estudio descriptivo que emplea instrumentos relacionales para caracterizar las situaciones que afectan a un grupo objeto de estudio, que permiten analizar los imaginarios sociales, las percepciones y formas de actuar respecto a la música. Además, persigue entender el pensamiento rítmico de los estudiantes, en función de una conceptualización acorde a su desempeño rítmico.

Neste trabalho transitaremos pelo conceito de presença que é o cerne da pesquisa denominada Por uma poética política: presença e ankoku butô. Tendo em vista alguns pilares que sustentam o entendimento de presença desenvolvido por Hans Ulrich Gumbrecht, o interligaremos mais precisamente à presença cênica do dançarino japonês Tatsumi Hijikata. Para tanto, adentraremos mais profundamente no trabalho deste artista, desvendando em sua proposta de pesquisa corporal a chave para a presença. Não por acaso, permearemos as qualidades corpóreas do shintai e nikutai que são possibilidades distintas desse corpo que dança.
Control of Growth Cone Polarity, Microtubule Accumulation, and Protrusion by UNC-6/Netrin and Its Receptors in Caenorhabditis elegans

UNC-6/Netrin has a conserved role in dorsal-ventral axon guidance, but the cellular events in the growth cone regulated by UNC-6/Netrin signaling during outgrowth are incompletely understood. Previous studies showed that, in growth cones migrating away from UNC-6/Netrin, the receptor UNC-5 regulates growth cone polarity, as observed by polarized F-actin, and limits the extent of growth cone protrusion. It is unclear how UNC-5 inhibits protrusion, and how UNC-40 acts in concert with UNC-5 to regulate polarity and protrusion. New results reported here indicate that UNC-5 normally restricts microtubule (MT) + end accumulation in the growth cone. Tubulin mutant analysis and colchicine treatment suggest that stable MTs are necessary for robust growth cone protrusion. Thus, UNC-5 might inhibit protrusion in part by restricting growth cone MT accumulation. Previous studies showed that the UNC-73/Trio Rac GEF and UNC-33/CRMP act downstream of UNC-5 in protrusion. Here, we show that UNC-33/CRMP regulates both growth cone dorsal asymmetric F-actin accumulation and MT accumulation, whereas UNC-73/Trio Rac GEF activity only affects F-actin accumulation. This suggests an MT-independent mechanism used by UNC-5 to inhibit protrusion, possibly by regulating lamellipodial and filopodial actin. Furthermore, we show that UNC-6/Netrin and the receptor UNC-40/DCC are required for excess protrusion in unc-5 mutants, but not for loss of F-actin asymmetry or MT + end accumulation, indicating that UNC-6/Netrin and UNC-40/DCC are required for protrusion downstream of, or in parallel to, F-actin asymmetry and MT + end entry. F-actin accumulation might represent a polarity mark in the growth cone where protrusion will occur, and not protrusive lamellipodial and filopodial actin per se. Our data suggest a model in which UNC-6/Netrin first polarizes the growth cone via UNC-5, and then regulates protrusion based upon this polarity (the polarity/protrusion model). UNC-6/Netrin inhibits protrusion ventrally via UNC-5, and stimulates protrusion dorsally via UNC-40, resulting in dorsally-directed migration. The polarity/protrusion model represents a novel conceptual paradigm in which to understand axon guidance and growth cone migration away from UNC-6/Netrin.
Limited Capacity or Involvement of Excision Repair, Double-Strand Breaks, or Translesion Synthesis for Psoralen Cross-Link Repair in Escherichia coli

DNA interstrand cross-links are complex lesions that covalently bind complementary strands of DNA and whose mechanism of repair remains poorly understood. In Escherichia coli, several gene products have been proposed to be involved in cross-link repair based on the hypersensitivity of mutants to cross-linking agents. However, cross-linking agents induce several forms of DNA damage, making it challenging to attribute mutant hypersensitivity specifically to interstrand cross-links. To address this, we compared the survival of UVA-irradiated repair mutants in the presence of 8-methoxypsoralen—which forms interstrand cross-links and monoadducts—to that of angelicin—a congener forming only monoadducts. We show that incision by nucleotide excision repair is not required for resistance to interstrand cross-links. In addition, neither RecN nor DNA polymerases II, IV, or V is required for interstrand cross-link survival, arguing against models that involve critical roles for double-strand break repair or translesion synthesis in the repair process. Finally, estimates based on Southern analysis of DNA fragments in alkali agarose gels indicate that lethality occurs in wild-type cells at doses producing as few as one to two interstrand cross-links per genome. These observations suggest that E. coli may lack an efficient repair mechanism for this form of damage.

The rapid development of science and technology resulted in increasingly tight competition on obtaining work. Moreover, with the implementation of the trade zone of the Asean Economic Community (AEC) currentlyits the realization of the Asia free market. There are eight professions involved in MEA competition, among which the the field of nursing, so the work readiness become important that a student should have when facing the world of work. This study was conducted to determine the influence of significants goal orientation, personality type, and campus climate on work readiness. Subjects in this study is 5 to 9 semester student of nursing and 1 and 3 semester of UIN Syarif Hidayatullah nurses profession student amounted to 151 are taken by purposive sampling technique. The results show that there an influence of goal orientation, personality type, and campus climate on work readiness is significant with the proportion of the variance is 63.6%. The hypothesis minor test show that emotionality, extraversion, conscientiousness, and teaching learning have a significant influence on work readiness. While learning goals, performance goals, honesty-humility, agreeableness, openness to experience, safety, interpersonal relations and the institutional environment have no significant effect.Suggestions for subsequent research in order to use other variables in order to enrich this study.   DOI:10.15408/tazkiya.v22i2.8399

INTRODUCTION: Ensuring adequate occlusal contacts and anatomy shape and form is always a challenge when placing extensive direct posterior composite resin restorations. The use of a correct technique, such as, an occlusal matrix can reproduce occlusal morphology more precisely. Additionally, recently, silorane-based or bulk fill composite resin present low shrinkage and were specifically designed for restoring posterior teeth.CASE REPORT: This report presents the clinical application of a low shrinkage composite resin system with a preoperative occlusal matrix in extensive composite resin restoration of a molar with hypomineralization. Acrylic resin was applied over the waxed tooth to copy the anatomic details. Cavity was prepared and bonding system was applied. Definitive layer in the occlusal matrix was applied and stabilized in position. Once curing was complete, occlusal matrix and resin excess were removed using a surgical blade.CONCLUSION: The application of these materials with occlusal matrix can provide a simpler technical approach, saving time and improving esthetic results.
