The 2D resistivity imaging method in mountainous area over different slope
Authors: Aziz Bakhtiar
Published: July 2017

Assessing the reliability of the 2D electrical resistivity imaging method is investigated in

mountainous areas. Several profiles are surveyed on different surface slopes ranging

between 17° to 55° degrees. Two types of electrode arrays with different electrode spacing

(2.0, 3.0 and 5.0 meters) are used. Repeated measurements are carried out for each profile

by using different field parameters such as data density, pulse duration and voltage. The

inverse sections are compared with the drilled bore holes in the area. The results show

that the 2D resistivity imaging works well in the mountainous area when suitable field

parameters are selected. The study has proved that the inverse sections are highly

sensitive to the number of data points. The optimal number of data points has direct

relation with surface slope, number of electrodes and electrode spread. On the other hand

pulse durations and voltages magnitude have no significant effects on the quality of the

field data. An empirical equation is suggested for the optimal acceptable number of data

points that has a direct relation to the profile length, number of electrodes, electrode

spacing and angle of the slope.

Published: July 2017

In this study, an attempted was made to estimate average of annual total surface runoff in the

northeastern Missan Governorate, south of Iraq by using Natural Resources Conservation Services

Curve Number (NRCS – CN) empirical technique in GIS platform. Thematic layers of soil

hydrological groups and LULC were created using ArcGIS 9.3 software. Intersection of these two

thematic layers generated a map with new polygons representing the merged hydrological soil group

and LULC. The appropriated CN values adapted from different sources and technical release of

United State of Department of Agriculture (USDA) were assigned manually for each new merged

polygon. The curve numbers for different antecedent moisture content (AMC) were calculated as 38,

59, 77 for dry, normal, and wet soil conditions. The associated maximum potential retention for each

AMC were calculated as 75,87, 176.51, and 414.42 for dry, normal, and wet soil moisture conditions.

Application of the method showed that the average annual runoff depth is 0.36 mm. This figure was

multiplied by the area of the study area (1856) km2 to get the total average of runoff volume 7424000m3 

which represents 0.0003 from the total annual average of rainfall. The applied method is robust

and easy to implement and could be used to roughly estimate the surface runoff with minimal data.

Esquivel! Space Age Sound Artist by S. Wood
Authors: Borle Sean
Published: July 2017

Wood, Susan.  Esquivel! Space Age Sound Artist, illustrated by Duncan Tonatiuh. Charlesbridge, 2016.This is a picture book that tells the story of Mexican composer, band leader and pianist, Juan Garcia Esquivel.  “Esquivel!”, as he came to be known, came from a poor family and became a very popular and wealthy composer.  He was a pioneer in sound art in the 1950s and 1960s, influencing many later composers of experimental music and sound art. The text is quite ordinary, factual material about the artist, with the exception of words representing sounds. These are often in bright colours, many shapes and sizes and different typefaces.  The differing scripts sometimes make reading the sentences difficult.  Some of the words and concepts are too high level for a picture book and most children at the picture book reading stage will not understand strange, weird and edgy music, so it is likely that this book will be most useful to older children. The artwork is the most interesting part of the book.  The images are all done in black-line, with colour fill being photographs of textures or patterns.  The other unusual part of the work is that Duncan Tonatiuh has drawn people in the style of ancient Mexican art, specifically the Mixtec codex.  Because this art predates the concept of perspective, all of the images are two dimensional and do not have depth.  Also all of the faces are drawn in the style of the ancient artworks.  The faces are all in profile with ears shaped like the number 3, pointy mouths and very flat forehead to nose profiles.  These sorts of details, while interesting to adults, will be lost on small children.The music message of this book is historical, highlighting Esquivel!’s early contributions to sound art.  The work also makes the point that Esquivel! had no formal musical training, showing that music is for everyone.  Because there is little written about this Esquivel! at a children’s reading level this book should be bought for public libraries and school libraries.Highly Recommended:  3 stars out of 4Reviewer:  Sean BorleSean Borle is a University of Alberta undergraduate student who is an advocate for child health and safety.

Parenteau, Shirley.  Bears in a Band.  Candlewick Press, 2016.This is a great little book.  Children will love the rhymes, which tell the story of four brightly coloured teddy bears, who pick up instruments and begin to play.  They make a joyful noise that eventually wakes “Big Brown Bear." Instead of being angry, Big Bear joins as a conductor and the music becomes even better.There are two music messages in this book.  First, parents should celebrate their children’s musical activities and accept that there will be noise.  Second, everyone should attempt to find the music in themselves, and share that with everyone.The text is simple.  Young children will quickly memorize it.  “The bears all play a noisy song/They don’t care if the notes are wrong." The images are happy, uplifting and full of warm fuzzies. This would be a good bedtime picture book for young children.   I highly recommend this book for libraries. Highly recommended:  4 stars out of 4 Reviewer:  Sean BorleSean Borle is a University of Alberta undergraduate student who is an advocate for child health and safety.
Isótopos estáveis de carbono e oxigênio em ostracodes do Cretáceo: metodologias, aplicações e desafios
Authors: Rodrigues Gislaine Bertoglio , Fauth Gerson
Published: July 2017

Ostracodes são microfósseis carbonáticos que têm se destacado na pesquisa de isótopos estáveis devido à rápida calcificação da carapaça, sua elevada sensibilidade aos parâmetros ambientais e à sua ocorrência em diferentes ambientes aquáticos. Os isótopos de carbono proporcionam informações sobre paleoprodutividade e disponibilidade de nutrientes dos oceanos e lagos. Os isótopos de oxigênio são utilizados para estimar a paleotemperatura e a paleosalinidade vigentes em determinada bacia sedimentar ao longo do tempo geológico. Até o momento, as análises isotópicas em carapaças de ostracodes são realizadas principalmente em material do Cenozoico, com poucas pesquisas realizadas para o Mesozoico. Esta técnica é amplamente utilizada em ostracodes de ambientes não-marinhos, sendo realizada com cautela em ambientes transicionais e marinhos, onde a composição da carapaça será semelhante à da rocha carbonática que o contém. Este texto compreende conceitos de isótopos estáveis, da técnica analítica utilizada, da realização das análises em ostracodes e da interpretação dos resultados nos estudos paleoambientais, e propõe um protocolo de pesquisa considerando as dificuldades de amostragem e de aplicação em carapaças do Cretáceo.

Published: July 2017

Embora o solo seja um importante elemento da paisagem, considerado essencial para o desenvolvimento das atividades humanas, ele é pouco conhecido pela população, tanto aquela composta de pessoas que lidam com o solo no dia-a-dia, direta ou indiretamente, como é o caso dos agricultores, como aquela composta de pessoas que constroem suas moradias e edificações na superfície do terreno. O presente estudo, aplicado em 10 turmas de alunos de 5a série do ensino fundamental de três escolas públicas da cidade de Marechal Cândido Rondon, Oeste Paranaense, entre os anos de 2007 e 2008, relata e analisa resultados de práticas pedagógicas que focalizam ensaios de germinação de sementes, decomposição de diferentes tipos de materiais e de infiltração de água no solo, para investigar progressos na compreensão das propriedades dos solos e na construção de uma consciência ambiental. Conclui-se que as atividades suscitaram a compreensão do solo como componente da paisagem geográfica e ajudaram a aplicar conhecimentos teóricos apreendidos em sala de aula.
Metodologia para estudos da qualidade das águas subterrâneas e sua aplicação para caracterização hidrogeoquímica do Aquífero Guarani
Authors: Campos Heraldo Cavalheiro Navajas Sampaio
Published: July 2017

O Aquífero Guarani é um dos maiores reservatórios de águas subterrâneas do planeta e representa uma reserva estratégica para os quatro países da América do Sul – Argentina, Brasil, Paraguai e Uruguai – onde ele ocorre. O município de Ribeirão Preto, localizado na região Nordeste do Estado de São Paulo, com uma população de mais 600 mil habitantes, é suprido inteiramente pelas águas do aquífero. Nesse município e região vem ocorrendo o uso intensivo de água subterrânea e uma numerosa quantidade de poços em atividade já evidenciam problemas de interferência entre eles. Ao mesmo tempo, percebe-se o aumento do risco de contaminação das águas subterrâneas por incremento de fontes instaladas sobre as partes aflorantes do aquífero (principalmente as relacionadas ao uso de agrotóxicos na agricultura), que são de alta vulnerabilidade. Este trabalho apresenta metodologia para investigação de dados de qualidade química de águas subterrâneas e sua aplicação para a caracterização hidrogeoquímica do Aquífero Guarani, no âmbito do território ribeirão-pretano e região.

Published: July 2017

É bem conhecido que ações antrópicas, como cortes, desmatamentos e adição de cargas podem afetar a estabilidade de encostas. O artigo sintetiza as principais abordagens de Geologia Estrutural para previsão e contenção de queda de blocos em encostas naturais e taludes rochosos. Os métodos de análise de encostas buscam avaliar situações de risco e minimizar riscos, apoiados no conhecimento de propriedades dos maciços, como composição litológica, estruturas e caracteres das descontinuidades, graus de alteração e consistência das rochas. A aplicação prática consistiu na avaliação dos resultados de levantamento executado por meio de rapel em talude na cidade de Santos, SP, por empresa de consultoria. O levantamento identificou os principais sistemas de fraturas e delimitou blocos em situações instáveis para eventual remoção ou estabilização. Este estudo revela a grande importância das juntas de esfoliação, feições que podem promover, graças à progressiva desagregação intempérica, progressivo desplacamento e desprendimento de massas de rocha encosta abaixo.

Rifampicin is one of the most important chemotherapeutic agents used in the treatment of tuberculosis. M. tuberculosis clinical strains resistant to rifampicin harbor mainly mutation in an 81-base pair region of rpoB. These mutations mainly consist of single amino acid substitutions. However insertions also can be related with rifampicin resistance strains. Herein, we described an insertion of 12 nucleotides in clinical isolates of M. tuberculosis resistant to rifampicin, all obtained from inmates. To evaluate the importance this insertion in surviving and drug resistance, it were carried out fitness experimental assays as well as in silico studies of 3D structural models, molecular docking simulations and virtual screening. The medical records of the seven patients showed all were previously treated to tuberculosis. Growth curves shown that the insertion determines a biological cost when compared to wild type rpoB and katG; or the double mutated rpoB S531L and katG S315T. From docking and molecular dynamics simulations it can be inferred that the insertion does not affect the process of synthesis of RNA transcripts. On the other hand, in the mutant RNAP-RIF complex rifampicin confirmed a low affinity interaction for the mutant form. Interesting, virtual screening for potential inhibitors for wtRNAP and mRNAP using a library of 1446 compounds approved by the FDA showed that the best ligands were mainly compounds with antibiotic activity, although the targets involved in the pharmacological action are other than RNAP. In conclusion, seven strains of M. tuberculosis RIF resistant that present an insertion of four amino acids in RNA polymerase showed by growth curve assays, a biological cost. Further, bioinformatics tools had characterized the putative drug resistance dynamic as well as the maintenance of RNA polymerase activity.
Distance-Vector Algorithms for Distributed Shortest Paths on Dynamic Power-Law Networks
Authors: D'Emidio Mattia , Frigioni Daniele
Published: July 2017

Efficiently solving the problem of computing, in a distributed fashion, the shortest paths of a graph whose topology dynamically changes over time is a core functionality of many today’s digital infrastructures, probably the most prominent example being communication networks. Many solutions have been proposed over the years for this problem that can be broadly classified into two categories, namely Distance-Vector and Link-State algorithms. Distance-Vector algorithms are widely adopted solutions when scalability and reliability are key issues or when nodes have either limited hardware resources, as they result in being very competitive approaches in terms of both the memory and the computational point of view. In this paper, we first survey some of the most established solutions of the Distance-Vector category. Then, we discuss some recent algorithmic developments in this area. Finally, we propose a new experimental study, conducted on a prominent category of network instances, namely generalized linear preference (GLP) power-law networks, to rank the performance of such solutions.

From previous experiences, it was suggested that stakeholders should collaborate in each phase of disaster risk reduction, in order to prevent and mitigate the impact of wide area natural disasters.

However, in several cases, the collaboration was not fruitful, owing to the diverse visions of both, private and public organizations’ operational continuity, resulting in conflicts occurring effortlessly among the organizations.

One of the solutions to overcome this challenge is applying the business continuity management (BCM) method, such as business impact analysis (BIA) and risk assessment, to the area. Japan International Cooperation Agency reported the “Area BCM” concept in 2013. This paper further investigates the concept of “Area BCM” and introduces the idea to decompose BIA factors for area and individual purposes, in order to build sustainable local economies.
RESEARCH INTO MECHANICAL PROPERTIES OF MINCED MEAT AND FINISHED PRODUCTS
Authors: Suсhenko Yuriy , Suсhenko Vladislav , Mushtruk Mikhail , Vasyliv Vladimir , Boyko Yuriy
Published: July 2017

Studies were conducted of the stressed-strained state of biopolymers of meat, which were exposed to the processes of elastic, residual and highly elastic deformation at cutting and mincing. Analysis of the structure of this natural biopolymer and the evaluation of mechanical characteristics of meat under normal and low temperatures are important factors that are taken into account for the rational selection of meat mincing machines and tools in the production of meat products, minced meat, semi-finished and sausage products.

The structure of meat is a system of structured protein fibers, impregnated with tissue fluid, which is protein sol that contains organic and inorganic substances, soluble in it. The tissues that the meat is composed of belong to natural biopolymers, so conducting analytical studies into mechanical properties of meat within the framework of our understanding of the mechanics of polymers will make it possible to improve mincing processes, employed during manufacturing of meat products.

In order to prevent meat overheating, the mincing process is performed at several stages. For example, in cutting mechanisms of choppers, they use a row of knives and grids with holes, diameter of which gradually changes from the original size of0.06 mto 0.003-0.002 min the outlet grids. Quality indicators of the finished products are affected by mechanical characteristics of raw materials and the way the cutting process is carried out.

In the course of conducted analysis it was found that in modern food production there remain unresolved important problems, which address current issues, related to rheological and structural mechanical properties of meat raw material. First of all, it concerns theoretical and practical developments that enhance an understanding of physico-chemical and mechanical properties of raw materials, which will make it possible to develop theoretical foundations and experimentally substantiate the new conceptual approach to solving the task of improving the quality of semi-finished products and durability of equipment at meat processing enterprises of APC. The research is the basis for constructive and technological solutions, choice of mode, kinematic and dynamic parameters of cutting devices, steel and wear resistant coatings for cutting tools that provide saving of energy and materials at meat mincing, high quality of minced meat. and finished products and appropriate service life of the equipment.

It was established that in order to determine characteristics of the strained state of meat, it is necessary to apply a circular diagram of loading-unloading, which allows analysis of behavior of the sample in a closed cycle of changing in external load. An analysis indicates a very large dependence of meat elasticity module on temperature. Dependences of this kind are generally characteristic of polymer bodies.
Four-derivative couplings and BPS dyons in heterotic CHL orbifolds
Authors: Bossard Guillaume , Cosnier-Horeau Charles , Pioline Boris
Published: July 2017

Three-dimensional string models with half-maximal supersymmetry are
believed to be invariant under a large U-duality group which unifies the
S and T dualities in four dimensions. We propose an exact, U-duality
invariant formula for four-derivative scalar couplings of the form
F(\Phi) (\nabla\Phi)^4F(Φ)(∇Φ)4
in a class of string vacua known as CHL
\IZ_N
heterotic orbifolds with NN
prime, generalizing our previous work which dealt with the case of
heterotic string on T^6T6.
We derive the Ward identities that F(\Phi)F(Φ)
must satisfy, and check that our formula obeys them. We analyze the weak
coupling expansion of F(\Phi)F(Φ),
and show that it reproduces the correct tree-level and one-loop
contributions, plus an infinite series of non-perturbative
contributions. Similarly, the large radius expansion reproduces the
exact F^4F4
coupling in four dimensions, including both supersymmetric invariants,
plus infinite series of instanton corrections from half-BPS dyons
winding around the large circle, and from Taub-NUT instantons. The
summation measure for dyonic instantons agrees with the helicity
supertrace for half-BPS dyons in 4 dimensions in all charge sectors. In
the process we clarify several subtleties about CHL models in
D=4D=4
and D=3D=3,
in particular we obtain the exact helicity supertraces for 1/2-BPS
dyonic states in all duality orbits.
On the non-linear relationship between VIX and realized SP500 volatility
Authors: G. Russon Manuel , F. Vakil Ahmad
Published: July 2017

VIX, a ticker symbol for Volatility Index, measures the implied annual volatility of at-the-money SP500 Index Options. Conventional wisdom presumes VIX to measure the magnitude (positive or negative) of possible movements in future equity prices, with movements being a positive function of VIX. This research investigates the nature of the relationship between VIX and SP500 volatility, and answers the question as to whether that relationship is linear or nonlinear. Based on this research paper, the authors conclude that the realized SP500 volatility is nonlinear, and grows with the level of VIX at an increasing rate. The nonlinearity relationship between VIX and SP500 has enormous implications for investment management and hedging in the financial markets.

LA TRAGEDIA DE LOS COMUNES EN LA COMPETENCIA VERTICAL ENTRE JURISDICCIONES
Authors: Krause Martín
Published: July 2017

Los beneficios de la competencia institucional se alcanzan bajo ciertas normas que impiden la violación de derechos y la depredación de los recursos. La competencia horizontal puede tomar la forma de agresión violenta entre jurisdicciones (guerra) o la de cooperación y comercio.Su impacto puede ser “negativo” si substrae recursos de gobiernos benevolentes comprometidos con el bienestar general de la comunidad, pero “positivos” si se los considera como otra forma de controlar el Leviatán.La competencia vertical muestra los mismos controles “positivos” potenciales y la misma necesidad de ciertas reglas para cumplir ese papel. Son similares a la definición estricta del derecho de propiedad que resuelve la “tragedia de la propiedad común”. De otra forma puede crear una situación donde los contribuyentes son abusados por distintos niveles de autoridad fiscal como muestra el caso argentino.
Estudio Comparativo Del Concepto De Regalías Contenido En Los Modelos De Convenio Para Evitar La Doble Imposición Y Su Alcance En Materia De Propiedad Intelectual
Authors: Delgado José Miguel Ceballos
Published: July 2017

La explotación económica de bienes intangibles, principalmente de aquellos que se encuentran protegidos por el sistema normativo de la propiedad intelectual, ha sobrepasado desde hace poco más de dos décadas las fronteras estatales.Con ocasión de esta situación de apertura económica, los titulares de los derechos económicos sobre estos bienes obtienen mayores ingresos, pero al mismo tiempo, cargas tributarias impuestas por los Estados en donde realizan actos comerciales sobre tales bienes. Esta situación da lugar al fenómeno de la doble imposición, la cual, en el caso de bienes intangibles recaerá principalmente sobre las regalías o utilidades que percibe el titular del derecho con ocasión de los usos que se realicen sobre tales derechos en los diferentes Estados.Pretendemos en este artículo, abordar el tema de la doble imposición internacional, pero centrándonos en los convenios que tienden a evitarla y haciendo especial énfasis en la definición de regalías o cánones que presentan tales convenios y los problemas que suscitan para la administración tributaria al momento de calificar una renta como regalía u otro ingreso; teniendo en cuenta que en el marco de los convenios para evitar la doble imposición, el acto de calificación puede determinar qué Estado debe ser el que ejerza la autoridad tributaria sobre el beneficiario de los ingresos.
