Authors: Baldev Singh Dr , S.N. Panda Dr , Gurpinder Singh Samra Dr
Published: July 2018

Cloud computing is one of the high-demand services and prone to numerous types of attacks due to its Internet based backbone. Flooding based attack is one such type of attack over the cloud that exhausts the numerous resources and services of an individual or an enterprise by way of sending useless huge traffic. The nature of this traffic may be of slow or fast type. Flooding attacks are caused by way of sending massive volume of packets of TCP, UDP, ICMP traffic and HTTP Posts. The legitimate volume of traffic is suppressed and lost in traffic flooding traffics. Early detection of such attacks helps in minimization of the unauthorized utilization of resources on the target machine. Various inbuilt load balancing and scalability options to absorb flooding attacks are in use by cloud service providers up to ample extent still to maintain QoS at the same time by cloud service providers is a challenge. In this proposed technique. Change Point detection approach is proposed here to detect flooding DDOS attacks in cloud which are based on the continuous variant pattern of voluminous (flooding) traffic and is calculated by using various traffic data based metrics that are primary and computed in nature. Golden ration is used to compute the threshold and this threshold is further used along with the computed metric values of normal and malicious traffic for flooding attack detection. Traffic of websites is observed by using remote java script.

Authors: Sudharshan Duth P , Ashok Kulkarni Vinayak
Published: July 2018

Today's technological advances in medical imaging have given rise to efficient diagnostic procedures. Segmentation identifies and defines individual objects with various attributes such as size, shape, texture, spatial location, contrast, brightness, noise, and context. Deformable segmentation methods are Active contours, which are used to match and track images of an atomic structure by determining constraints derived from the image data. Level set method is an integral part of active contour family, considerable work towards level set methods has identified two main disadvantages i.e., initialization of controlling parameters and time complexity. In this paper, the methodology employed proposes an enhanced Variational level set methodology for Magnetic Resonance (MR) brain image segmentation with heterogeneous intensity. Core concept of IFCM is based on Intuitionistic fuzzy set. Both the values of membership and non membership values for the purpose of labelling are utilized together. As the result of experimentation reveals the efficiency of the recommended IFCM algorithm and Lattice Boltzmann Method (LBM) to overcome the drawbacks of Level Set methods by using the energy function to reduce the processing time which addresses the time complexity issue. The proposed system combines of both IFCM and LBM to form a novel approach. The system is tested on a large set of MRI brain images, extensive research and experiments were carried over on the standard dataset and the results are found to be improved in identification of tumor size detection with respect to time complexity.

Published: July 2018

Text files utilize substantial amount of memory or disk space. Transmission of these files across a network depends upon a considerable amount of bandwidth. Compression procedures are explicitly advantageous in telecommunications and information technology because it facilitate devices to disseminate or reserve the equivalent amount of data in fewer bits. Text compression techniques section, the English passage by observing the patters and provide alternative symbols for larger patters of text. To diminish the depository of copious information and data storage expenditure, compression algorithms were used. Compression of significant and massive cluster of information can head to the improvement in retrieval time. Novel lossless compression algorithms have been introduced for better compression ratio. In this work, the various existing compression mechanisms that are particular for compressing the text files and Deoxyribonucleic acid (DNA) sequence files are analyzed. The performance is correlated in terms of compression ratio, time taken to compress/decompress the sequence and file size. In this proposed work, the input file is converted to DNA format and then DNA compression procedure is applied.

Published: July 2018

Cloud Computing has been intrinsically changing the way we utilize computers to keep and retrieve our personal & business data. With the advent of this emerging paradigm of computing, it arises the new security challenges. Existent cryptographic data security techniques i.e., encryption deteriorated in preventing data theft attacks once the key is compromised, especially those perpetrated by insiders. Cloud Security Alliance reckoned this threat as a significant danger of Cloud Computing. Although the majority of Cloud users are very much known of this risk, they are leftover with the only choice of trusting the cloud service provider, regards to their data protection. In this paper, we propose an alternate way to secure data on the cloud which is more efficient and secure by the concoction of user profile mapping using Hadoop framework and offensive decoy technology.

Parametric study of flyash based geopolymer concrete
Authors: Kumar Das Sourav
Published: July 2018

With the growth of civilization the demand of cement concrete is increasing rapidly which increase the production of cement and abolishing the natural source of limestone. Also contributing a lot to the global warming by generating huge amount of carbon-di-oxide. Therefore the present study concentrate on the production of concrete using the geopolymerization technology which replaces cement fully by fly ash, a waste material and alkali solution. India is presently producing approximately 190 million tons of fly ash every year from moreover 145 power plants. Present research is focused on the different parameters which are curing temperature, ratio of sodium silicate to sodium hydroxide, molarity of sodium hydroxide, curing type and the results have been studied and discussed. Previous works emphasis that only the use of fly ash as the base material confine the concrete to be heat cured which limits the applicability of geopolymer concrete to cast-in-situ conditions. So some proportion of flyash is replaced by ground granulated blast furnace slag (GGBFS) and the effect on compressive and tensile strength is observed. Ambient temperature dry curing was done without any water when some proportion of fly ash was replaced by GGBFS. The ratio of sodium silicate solution to sodium hydroxide solution by mass was kept fixed at 2.5 and the concentration of sodium hydroxide was kept 14M. The ratio of flyash to alkali solution was kept 0.35 & 0.40. Replacing 40% of Flyash by GGBFS and keeping the concentration of NaOH as 14M at ambient temperature, the compressive strength encountered was 40 MPa.

Epistemologia Kanta jako rozwiązanie sporu empiryzmu z racjonalizmem
Authors: Wendland Michał
Published: July 2018

The article concerns some of the most important elements of I. Kant’s epistemology and its connections with earlier epistemological ideas, namely rationalism and empiricism. The history of dispute between rationalism (Descartes, Leibniz) and empiricism (Locke, Berkeley, Hume) is hereby shortly presented while Kant’s own philosophical achievements are suggested to be both alternative and synthesis of these. The main core of this paper is summary of basis of Kant’s Critique of Pure Reason; some most important categories are described: apriorism, synthetic and analytical judgements, knowledge a priori and a posteriori, main ideas of transcendental esthetics (two forms of pure intuition: time and space), main ideas of transcendental logic (forms of judgement and twelve categories). Also the meaning of Kant’s „copernican revolution” is presented as a turning point for classical German philosophy as well as for whole modern epistemology.
Jerzy Kmita – interpretacja humanistyczna i społeczno-regulacyjna koncepcja kultury
Authors: Bonecki Mateusz
Published: July 2018

This paper presents two main topics which Jerzy Kmita addresses in his methodological writings. The first one involves the conception of “humanistic interpretation” which Kmita describes as a kind of reasoning and explanation applied within the humanities. The second consists in the so called “socioregulatory definition of culture”, according to which culture is identified with a set of intersubjective beliefs guiding and regulating human actions. Based on both methodological concepts, humanities may be defined as a range of academic disciplines which in the course of humanistic interpretation hypothetically ascribe cultural beliefs to social agents in order to explain their behavior.
Czym była Marksowska krytyka ekonomii politycznej?
Authors: Nowak Krzysztof
Published: July 2018

The present paper reconstructs the peculiarities of Marx’s critique of classical political economy. The first section recalls three main intellectual sources of Marxism: Classical German Philosophy, French Utopian Socialism, and English Classical Political Economy. The second section focuses on reasons why the Marxian thought has often been considered as passé. The third part shows that many examples of downgrading or even rejecting Marx’s propositions resulted from misunderstanding of the peculiarities of his method of investigation. Finally, the paper analyses possibilities of bringing back the Marx’s critique of political economy into scientific interests, for instance, in the form of modern crisis theory.

Dialog na styku kultur — Bieszczady
Authors: Węcławiak Alicja
Published: July 2018

Eastern Slavonic cultures are often a conglomeration of patterns of several cultures, which resulted from the past. As Paul Ricouer said, the past is a place of our hidden identity, hurt by the greatest disaster of the twentieth century — bloody regimes. Nazism and bolshevism left their mark on the western world, whose painful consequences we still face today. Bieszczady is a part of Poland, which suffered particularly acutely during and after WWII. It is a place with a kind of a legend, becoming more and more appreciated, because of its tourist attractions, unspoiled nature, magical and largely virginal landscapes. This is a very important area for Slavonic identity, a place with a rich and troubled history — Bieszczady witnesses the actions of the Ukrainian InsurgentArmy and Operation “Vistula”. This article concerns this question, presents excerptsof interviews and memories of participants in those events and shows Bieszczady as a region of the heterogeneous Slavonic culture and a place of memory — both individual and collective.
„U nas adin prokuror czestnyj czeławiek, a i on — prawdu skazat’ — swinia” — „rossica” w felietonistyce Stanisława Michalkiewicza
Authors: Dzienisiewicz Daniel
Published: July 2018

The article aims at presenting and analyzing rossica (linguistic and culturalborrowings from Russian) retrieved from the texts written by Stanisław Michalkiewicz. Stanisław Michalkiewicz is a conservative-liberal author and a former politician. Along with borrowings from Latin and French, Michalkiewicz, known for his command of Russian, incorporates various Russian and Soviet linguistic and cultural elements in his writings. Rossica come in the form of lexical and textual borrowings, e.g. quotations from politicians, literary works, popular songs and jokes. One can also distinguish indirect sources of rossica, such as quotations from Polish literary works referring to Russian reality. Moreover, Michalkiewicz creates original derivates of Russian borrowings and modifies the forms of dative case of Polish personal names according to the Russian masculine noun declension paradigm.
Influencia geomorfológica en la vulnerabilidad a incendios forestales en el Área de Conservación Guanacaste, Costa Rica
Authors: Vargas-Sanabria Daniela , Quesada-Guzmán Adolfo
Published: July 2018

El bosque tropical seco ubicado en el pacífico norte de Costa Rica es afectado de forma recurrente por incendios forestales, lo que impulsa cambios en la dinámica del paisaje, así como en los valores socioeconómicos y ecológicos del ecosistema. El objetivo del estudio es determinar las relaciones de la geomorfología en la vulnerabilidad a incendios forestales en el Área de Conservación Guanacaste, a partir de la relación entre el origen y la edad del material parental, así como la dinámica, morfología y evolución de las geoformas con las condiciones climáticas regionales y el bosque seco. Se realizó una cartografía geomorfológica con dos grupos genéticos: endógeno-modelado (cerro El Hacha, rampas volcánicas del complejo Orosí-Cacao, colinas tectónicas de Santa Elena) y exógeno (planicie costera). Se utilizó un modelo de vulnerabilidad a incendios forestales, que contempla componentes socioeconómicos y ecológicos; y, por último, se llevó a cabo un análisis cruzado entre las formas de relieve y el modelo de vulnerabilidad mediante el cruce de datos geoespaciales. Los resultados muestran que el porcentaje entre las formas de relieve y los rangos de vulnerabilidad indican un patrón en la morfología y el comportamiento en la composición de las laderas, orientación y localización. El estudio representa un acercamiento en la determinación de relaciones causales y dinámicas entre las formas de relieve y la vulnerabilidad a incendios forestales en el Área de Conservación Guanacaste.

O Argumento do Milagre comete a Falácia da Taxa-base? Apresentação, Estado da Arte e Questões de Formalização
Authors: De Souza Pedro Bravo
Published: July 2018

Objetivamos discutir a crítica, avançada por Colin Howson em Hume's problem, segundo a qual o argumento do milagre (doravante, AM) comete a falácia da taxa-base. Por falácia da taxa-base, entende-se a negligência do valor da probabilidade prévia de determinada hipótese ou teoria T, P(T). Por sua vez, em uma de suas versões, AM assere que apenas assumindo que uma teoria científica madura T é aproximadamente verdadeira não faz de seu sucesso preditivo um milagre. Formalizado probabilisticamente, Howson argumenta que a conclusão de AM, a probabilidade de que a teoria T seja aproximadamente verdadeira é grande, apenas se segue se assumirmos para T um valor não-negligenciável. Tal crítica de Howson despertou duas categorias de reação na literatura especializada: supondo que AM comete a falácia da taxa base, alguns autores propuseram abandonar AM enquanto um argumento para a tese epistemológica do realismo científico, ao passo que outros defenderam que apenas uma versão de AM comete a falácia da taxa-base; defendendo que AM não comete a falácia da taxa base, certos autores alegaram alguns problemas na formalização probabilística de AM, enquanto outros buscaram refinar tal formalização de modo que a nova evite a falácia em questão. Tendo apresentado esse estado da arte, investigaremos se a formalização probabilística do argumento do milagre é razoável. Discutiremos se ela acomoda a natureza de inferência à melhor explicação pressuposta no AM. Por fim, indicaremos, brevemente, algumas dificuldades para a crítica de Howson ao assumir-se que AM instancia, na verdade, uma abdução Peirceana.
Modernidade para quem?: o negro e a urbe paulistana
Authors: Silva Sheila Alice Gomes Da , De Leão Esteves Felipe Eugênio
Published: July 2018

Resultado das discussões engendradas para a composição da dissertação de mestrado intitulada: “Negros em Guaianases: Cultura e Memória”, o presente artigo estabelece uma contextualização a partir dos processos migratórios do campo para o território urbano, tendo como atores grupos negros e imigrantes, sobretudo, italianos, para refletir sobre os processos de urbanização da cidade de São Paulo. Pautados numa modernidade elitista e de caráter eurocêntrica, impressa - na segunda metade do século XIX e nas primeiras décadas do século XX - nos territórios centrais da urbe, nos leva a identificar consequências sobre a presença dos grupos negros que habitavam as respectivas regiões. Em nome de um projeto civilizatório baseado na projeção europeia de embelezamento e de progresso, levado a frente por uma incipiente burguesia urbana, ações higiênicas de extrema violência expulsaram e segregaram tais populações. Logo, pergunta-se: Modernidade para quem? Mais do que uma cidade buscando um pseudo desenvolvimento, seu ideal era branco, europeu, não havia espaços para os negros. A modernidade buscada se fez seletiva e discriminatória, num movimento materializado no tecido urbano que destacou privilégios de uns a custa da invisibilidade de outros.

Abstract:

Introduction: Congenital structural clubfoot is the most common congenital deformity of the foot. Despite successful treatment, the affected side may present signs of athrophy, differences in length, functional maldevelopment and in some cases it may also result in pain. Although several international studies have been investigating the quality of life of individuals with clubfoot, no research has been done in Hungary. Patient-based assessment is used for the evaluation of the effectiveness of treatment and for the comparison of the traditional versus the Ponseti method. Aim: To gain permission for the use of the internationally most well-known Clubfoot Disease-Specific Instrument (hereafter: ‘Clubfoot Specific Questionnaire’) consisting of 10 items and two subscales, and furthermore, to adapt its parent and child-version for Hungary and to carry out the internal and external validity testing of the measure. Method: The Questionnaire was completed by 75 individuals (44 boys, 28 girls) belonging to three age groups (under age 12, aged 12–17.99 years and those aged above 18); the mean age was 12.45 years (range: 2–44 years). The measures used: the Hungarian version of the ‘Clubfoot Specific Questionnaire’ (adapted versions for the given age groups), and the Hungarian version of EQ-5D-3L to measure the general quality of life. Results: Both the parent- and the child-version of the ‘Clubfoot Specific Questionnaire’ showed adequate internal validity (parent-version: 0.872, child-version: 0.923); the individual items showed medium to strong correlations with the EQ-5D-3L dimensions besides the existing significant connections. Conclusion: The Hungarian adaptation of the measure proved to be successful. The validated questionnaire provides a further tool for the assessment of the quality of life of individuals with clubfoot and also for the evaluation of the success rate of therapies.

Komplex jellegek genetikai hátterének elemzése

Published: July 2018

Abstract:

Although the Human Genome Project discovered the sequence of the human genetic information 15 years ago, genetic background of the diseases – primarily that of complex disorders – is still not known. The sum of the not yet discovered inherited risk factors is termed the missing heritability; the identification of these genetic components is, however, essential, as it is the base of the understanding of the molecular pathomechanism of diseases. It is not only of theoretical importance: this knowledge can be used in the clinical practice, as it offers the possibility of improvement of diagnostics, prevention as well as targeted and individualized therapy. Application of novel and more efficient molecular biological tools contribute to the discovery of unknown genetic factors, the complete goal can only be achieved, however, by re-conceptualization of several clinical and genetic points. Our knowledge was established by genome-wide studies, however, further knowledge must be acquired according to the following points: (1) genotype and association analysis of repeat variations (VNTRs and CNVs) besides SNPs, (2) investigation of gene–gene and gene–environment interactions, (3) epigenetic studies, (4) assessing the biological function of polymorphisms, (5) application of biologically relevant diagnostic categories and endophenotypes. Although it is only 1.2% of the whole genome that codes for proteins, however, as much as 90% is transcribed to RNA, consequently it can be hypothesized that gene expression analyses might offer promising starting points for further studies, as they can shed light on the molecular processes that contribute to the development of diseases.

Conformal Coating of Metallic Shells on Carbon Nanotube Turfs
Authors: Zbib Mohamad B. , Howard Matthew , Maughan Michael R. , Briot Nicolas J. , Balk T. John , Bahr David F.
Published: July 2018

A synthesis method to form conformal core-shell foams of metals and alloys on a carbon nanotube (CNT) scaffold by electroplating from a single bath electrolyte is demonstrated in this work. A triple cyclic pulse electrodeposition technique was used to deposit Ni and Cu layers on the CNT scaffold, and electron microscopy was then used to identify conditions amenable to conformal and island growth morphologies. Nanoindentation of the resulting metallic foam structure, using a flat punch/compression geometry, demonstrates that adding conformal metallic shells to the CNT turf to create a metal coated low density foam increases both the hardness and elastic modulus; however, once island growth initiates there is no significant subsequent increase in mechanical properties with increases in deposited metals.

Published: July 2018

O desenvolvimento mineiro ocorre em diversas etapas. Na fase inicial da atividade de mineração realiza-se uma análise prévia para quantificação e qualificação do minério passível de ser extraído de modo rentável, constituindo-se em uma gestão dos recursos e reservas minerais. Essa etapa é fundamental por caracterizar-se como fator de determinação para maximização da recuperação do minério, o que implica na vida útil e lucratividade do empreendimento mineiro através do reconhecimento geológico do depósito mineral que está sujeito de ser materializado por vários tipos de modelos. Neste contexto, é fundamental a elaboração de um modelo geomorfológico representativo do corpo mineralizado baseado em informações recolhidas por meio de técnicas de prospecção geológica e levantamentos de campo. Por ser realizado na fase inicial, a precisão dos resultados desses trabalhos geralmente não se constitui fator decisivo na seleção dos alvos de pesquisa de detalhe devido à carência de dados de campo e necessidade de custos reduzidos, sendo admitidas variações de até 30% nos valores determinados. O desenvolvimento contínuo das ferramentas computacionais permite que modelos geomorfológicos das ocorrências minerais possam ser elaborados de maneira rápida e precisa com baixo custo operacional. Neste sentido, o objetivo deste trabalho foi desenvolver uma metodologia para modelagem geométrica de maciços rochosos a partir do uso de softwares de baixo custo e ilustrar na prática a aplicação da mesma para determinação do volume de maciços rochosos.

Published: July 2018

Com a constante evolução tecnológica das indústrias, os materiais ferrosos, antes de sua utilização final, são submetidos a diferentes tratamentos térmicos para proporcionar melhores propriedades mecânicas e microestruturais que o material pode adquirir. Este procedimento pode ser verificado através de componentes mecânicos no qual a dureza é uma característica fundamental no projeto. Assim, para aumentar a dureza e a resistência do material, aplica-se o tratamento térmico de têmpera. Essa técnica consiste em aquecer o material acima da temperatura crítica do aço e resfriar em água ou óleo. O objetivo do presente estudo é analisar as propriedades mecânicas resultantes da realização do tratamento térmico de têmpera em corpos de prova de aço ABNT 8640 com o modo de resfriamento em água. Foram realizados ensaios de tração e de dureza em todas as amostras, além da análise microscópica. Comprovou-se que ocorreu o aumento da dureza nos corpos de prova, bem como a mudança estrutural dos tamanhos de grãos. Além disso, verificou-se que a têmpera, a partir de 1100°C, resulta na redução das propriedades mecânicas do aço ABNT 8640.

Os estudos mineralógicos dos solos dessa região são escassos, entretanto, esse conhecimento é de grande importância, tanto na caracterização e classificação dos solos, como na elucidação de sua gênese, onde assume relevante importância a classificação do resíduo pesado das frações areia. A caracterização desses solos dados se deu com o auxílio do mapa dos solos do Estado do Ceará da Embrapa e com a contribuição da técnica de Difração de Raios-X (DRX) que corresponde a uma das principais técnicas de caracterização microestrutural de materiais cristalinos, onde, de todos os métodos da química analítica para a caracterização de matérias, somente a DRX é capaz de fornecer informações qualitativas e quantitativas dos minerais constituintes de uma mistura. Portando, tem-se que a área estudada está inserida em uma região com Argissolos vermelho/amarelo eutróficos, com inclusões de luvissolos e neossolos litólicos eutróficos, com uma predominância de três minerais: quartzo, fluoropatita, carbonato de cálcio e óxido de urânio, além da presença das principais classes de argilosminerias.

This study aimed to develop microemulsion through of ternary system composed of brine (aqueous phase), vegetable oil (oil phase), and non-ionic polyethoxylated surfactants, T20 and T80. From the ternary diagrams obtained, two systems were chosen in the regions of microemulsion (Winsor IV) and, subsequently, were conducted rheological study, at different temperatures, and cloud point studies of these systems. The results showed that the microemulsion of T20/brine/vegetable oil presented thermal stability up to 53° C and microemulsions of T80/brine/vegetable oil of 72o C, that could be due a change in micelle morphology and cloud point of each microemulsion system. The rheological results indicated non-Newtonian behavior, adjusted by Herschel - Bulkley model.

O objetivo deste artigo é analisar como artesãos significam o trabalho que realizam. Para coleta de dados, utilizamos versão reduzida do instrumento de pesquisa construído pela equipe Meaning of Work International Research Team – MOW – durante os anos 1980, traduzido e validado no Brasil por Soares (1992). Conforme orientação do modelo teórico adotado, o significado do trabalho é analisado a partir de três dimensões: centralidade do trabalho, normas sociais do trabalho e resultados e objetivos valorizados do trabalho. A partir da realização de análises estatísticas descritivas examinamos o comportamento da amostra de artesãos investigados frente às dimensões que integram o modelo de significado do trabalho da equipe MOW (1987). Adicionalmente, operamos a comparação entre médias de quatro perfis de artesãos, para as dimensões citadas. A média de centralidade absoluta do trabalho para os artesãos é alta e não foi observada diferença relevante entre as médias dos quatro perfis analisados. Quanto à centralidade relativa, o trabalho obteve segunda maior média. Os artesãos do Cariri cearense apresentaram uma adesão levemente superior às normas de direitos quando comparadas às normas de deveres. No exame da dimensão resultados esperados do trabalho, encontramos diferenças entre as médias dos quatro perfis e na ordem dos resultados mais valorizados.

Este trabalho relata a identificação de algumas classes de compostos presentes nos extratos etanólicos e hexânicos da Bixa orellana (Urucum). Para os testes fitoquímicos realizados, os extratos foram obtidos de diferentes partes da planta (folhas, sementes e caule) as quais foram secas e submetidas ao processo de extração a frio em separado com os solventes hexano e etanol. Assim, obtiveram-se os extratos etanólicos e hexânicos da espécie. As classes de compostos investigadas foram fenóis, taninos, antocianinas, antocianidinas, flavonóides, leucoantocianidinas, catequinas, flavanonas, saponinas, antraquinonas, alcalóides, triterpenóides e esteróides. Os testes apresentaram resultados positivos para alguns extratos, que revelaram a presença de flavanonas, flavonóis, xantonas, saponinas, flavonóides, antraquinonas livres, alcalóides, triterpenóides e esteróides. Conclui-se que os resultados encontrados no estudo confirmam os dados apresentados na literatura pesquisada.
Sensor-based time-dependent formation factor in prediction of chloride ingress in mortar
Authors: Rangelov Milena , Nassiri Somayeh
Published: July 2018

Characterisation of chloride ingress rate is crucial for service life predictions in reinforced concrete. In this study, the time-dependent chloride diffusion coefficient (DCl(t)) was determined using real-time non-destructive embedded sensors. First, the time-dependent formation factor was established based on continuous electrical conductivity data from the sensors, which provided DCl(t) by the Nernst–Einstein equation. Twelve mortar mixtures were included that varied in water/cementitious materials ratio (w/c) and supplementary cementitious material (SCM) content. A numerical model of chloride diffusion using the established DCl(t) was developed by solving Fick's second law of diffusion using the finite-difference method. The model's predictions agreed well with experimental chloride profiles available in the literature. The results of chloride ingress simulation for all tested mixtures clearly showed the effect of reducing the w/c and using more SCM on slowing the rate of chloride ingress. Furthermore, the developed DCl(t) relations were used to establish a diffusion decay coefficient (mdiff) for all tested mixtures, leading to the development of empirical formulations for DCl(t) and mdiff as a function of w/c and SCM content. The results of this study demonstrate the potential of the implemented non-destructive technique in efficient assessment of transport properties of mortar related to chloride ingress.

El objetivo de esta investigación fue medir el grado de conocimiento, que tienen las empresas legalmente constituidas  de Norte de Santander,  con respecto a este tema de la seguridad laboral, con la finalidad de tener un panorama claro que pueda determinar las posibles estrategias que faciliten esta transición;  Este nuevo SGSST obliga a los empleadores a realizar un reconocimiento permanente de las condiciones de trabajo que inciden en el bienestar, la seguridad y la salud de los trabajadores, permitiendo realizar las acciones de mejora. El no cumplimento de estas  traerá sanciones económicas y hasta puede ocasionar el cierre definitivo de las empresas.
Influencia del agua en el desempeño de los pavimentos: lluvia ácida
Authors: Obando Gamboa Carlos Javier
Published: July 2018

El agua superficial contribuye en la oxidación del asfalto, más aún cuando ingresa por los poros de la capa de rodadura, sin embargo, el mayor efecto destructivo se manifiesta en forma combinada con las cargas del tráfico ya que el agua alojada en las fisuras, poros e intersticios del pavimento por efecto de la presión de los neumáticos, genera una presión de vacíos que gradualmente destruye el pavimento asfáltico. Es conocido que diferentes agentes químicos pueden modificar las características mecánicas y desempeño de los concretos asfálticos, esta es la base para el uso y desarrollo de diferentes modificadores con el objeto de mejorar el comportamiento del asfalto frente a diferentes solicitudes y/o factores, así mismo las adiciones y aditivos en los pavimentos hidráulicos. Partiendo del hecho que existen agentes químicos y que el agua superficial puede infiltrarse en el concreto asfáltico e hidráulico, y que ésta sometida a fuerzas externas causarán inevitables esfuerzos internos adicionales, podemos inferir que los agentes químicos presentes en el agua de escorrentía o agua lluvia podrían verse potencializados, modificar el comportamiento mecánico de los concretos utilizados en los pavimentos, acelerar los procesos de envejecimiento y causar daños estructurales.
