Discrete Space-Time on the Manifestation of Mass
Authors: Austin Rickey W.
Published: February 2018

Schwarzschild’s Metric (Schwarzschild 1916) under specific conditions provides a Taylor series first order discrete length when transforming coordinates between observers. Exploring the consequences of the discrete length produces an a priori result of quantized space-time. Deriving base units from the quantization of space-time and applying elementary charge, exact formulations for the observed Schwarzschild’s discrete units are obtained. These units are equivalent to Planck’s mass, length, time, momentum, force, energy and Planck’s constant (NIST CODATA 2014).

Introduction: Malnutrition is a public health problem in developing countries. The prevalence of malnutrition at the national level hardly reflects the reality in hospitals. It is in this context that we assessed the nutritional status of children from 2 months to 5 years hospitalized in the pediatric ward of the regional hospital and the Ziguinchor Peace Hospital. Materials and methods: This was a prospective study from June 1 to October 30, 2016. Children aged 2 to 60 months, hospitalized in one of the two services, were included. Children with esdato-ascetic syndrome were not included. Epidemiological, anthropometric data, and associated diagnosis were studied. Results: We included 114 children (70 boys and 44 girls). The average age was 21.9 months [4-59]. Forty-two point one percent (42.1%) of infants <6 months were breastfed exclusively with breast milk. The weaning of children was done early in 55.3%. The mean age of mothers was 26.6 years [17-38]. The socioeconomic level was low in 62.3% of cases. The prevalence of malnutrition averaged 35.5% for underweight; 32.9% for wasting and 32.0% for stunting. Acute respiratory infections (ARI) and acute gastroenteritis were the most common associated conditions. Mean hospital stay was 8 days ± 009 [3-28]. About two thirds of the patients (n = 72) had a hospital stay of more than 7 days. Malnutrition was significantly associated with multiparity, low socioeconomic status, hospital stay of more than 7 days and infectious diseases. Conclusion: Infections and a hospital stay longer than a week are factors favoring malnutrition in children from 2 months to 5 years.

The newer tendencies of research, related with the leaching of precious metals, involves the use of non toxic reagents that allows the leaching of a mineral of sedimentary origin using the system S2 - O3 2- - O2. Prior to thisprocess, the mineral was characterized by Scanning Electron Microscopy (SEM) in conjunction with Energy Dispersive Spectrometry of X – rays (EDS), X- ray mapping. Finally, the chemical composition was executed by Inductively Coupled Plasma Spectrometry (ICP). According to the results obtained, it was possible to determine that the mineral studied has adequate contents of gold, palladium, silver, and platinum. And after the leaching process, it could be possible to leach the gold and palladium that it contains, getting recoveries of 90% and 85 %, respectively. In the case of silver, a redissolution or precipitation could occur during the first minutes of reaction.

Food safety is still a very important topic of interest. The use of medicinal plants extracts can be an efficient alternative for fighting food-borne infections in the face of the increase of resistance to antibiotics. We have studied the sensitivity of bacterial strains isolated from food outlets using commonly used antibiotics (Amoxicillin, Vancomycin, Ceftriaxone, Teicoplanin, Rifampicin and Amikacin). This was done using an antibiogram. We have also tested their sensitivity against essential oils extracted from medicinal plants (Cinnamomum verum, Eucalyptus globulus, and Glycyrrhiza glabra L) using aromatogram. This study was conducted using 27 bacterial strains, including 9 Escherichia coli strains, 9 Staphylococcus aureus strains, 9 Salmonella spp. strains, and 3 ATCC strains (E. coli ATCC 25922, Staphylococcus aureus ATCC 25923 et Salmonella typhimurium ATCC 14028). Results revealed that two plant extracts has a substantial antibacterial activity with zones of inhibition ranging from 10 to 25 mm, and it reached 35 mm when using a cocktail of plant extracts. Regarding the antibiotics we used, all strains of Salmonella spp. demonstrated a resistance to amoxicillin and to ceftriaxone. The tested strains of E. coli and Staphylococcus aureus had a partial resistance to the tested antibiotics, which confirms the results of previous studies.

Sobre la idea de justicia en Marx
Authors: Mora Alonso César Augusto
Published: February 2018

El artículo se concentra en indagar las diferentes declaraciones de Marx sobre la justicia, con la intención de determinar tres cuestiones: en primer lugar, saber si nuestro autor cuenta con una concepción de la justicia; en segundo lugar, establecer si la reflexión acerca de lo que es justo ocupa un lugar privilegiado en su obra; y, en tercer lugar, ver si a partir de ahí puede colegirse la existencia de una teoría marxiana de la justicia. De especial interés resulta la presencia de argumentos con implicaciones éticas y morales en estos asuntos.
Estado nacional, globalización y democracia
Authors: Valenzuela Pérez Wilson Alcides
Published: February 2018

La definición de Estado nacional que Hans Kelsen expone en su obra clásica del pensamiento jurídico Teoría general del Derecho y del Estado lo caracteriza como organización política, que crea una comunidad nacional con el objeto de ejercer el poder político en el marco de un orden normativo válido para un espacio territorial delimitado, mediante el cual, se garantiza el principio de autodeterminación de un pueblo y su complemento necesario: la soberanía. Sin embargo, con motivo de los procesos de globalización, en particular, globalización de la economía de mercado, las decisiones más importantes que afectan al Estado se toman en los organismos económicos internacionales como el Fondo Monetario Internacional o el Banco Mundial, con lo cual, los principios de autodeterminación y de soberanía propios de la clásica definición del Estado nacional son puestos en cuestión y se han convertido en una mera ficción. Ante esa realidad, la idea de una sociedad cosmopolita, postulada por Kant hace ya más de doscientos años, retoma su vigencia, salvo que ahora, a la distancia histórica, la propuesta kantiana debe ser implementada por la democratización de los procesos de constitución de un nuevo orden mundial. El presente artículo explora la posibilidad de fortalecer la democracia gracias a una reconstrucción de los principios de la Ilustración, aplicados a una sociedad cosmopolita mediante la práctica del poder comunicativo de los ciudadanos que, suponemos, producirá el desencadenamiento de las libertades comunicativas en el horizonte teórico propuesto por Habermas.
Performatividad y afectos
Authors: Di Giorgi-Fonseca Luz Helena
Published: February 2018

Un tema transversal que aparece en la obra de la filósofa Judith Butler, especialmente en Vida precaria y Marcos de guerra, tiene que ver con la experiencia afectiva que tienen los sujetos. Por esta razón, el objetivo del presente artículo teórico es analizar la manera como la filósofa norteamericana trata el tema de los afectos o las emociones. El texto se centra en demostrar la pertinencia de la reflexión en torno a los afectos, ya que es un elemento crítico-social que ayuda a comprender la constitución de la subjetividad y la agencia, tanto individual como colectiva; asimismo, pretende ofrecer nuevos aportes para el entendimiento de las situaciones contemporáneas de discriminación y opresión, pero también de resistencia en contextos democráticos. Aun cuando el sujeto, desde sus experiencias afectivas, se encuentra condicionado por los marcos normativos sociales, es posible pensar en luchas desde el afecto, como una salida ante los efectos restrictivos que este genera.
Metaphoric Perceptions of Engineering Students Regarding Concepts of Science, Technology and Design
Authors: PALİÇ ŞADOĞLU Günay
Published: February 2018

The purpose of this study is to identify perceptions of students studying at faculty of engineering regarding science, technology and design through metaphors. The sample group is consisted of a total of 130 students who are at the first, second, third and fourth year of their education in civil engineering department of a state university in the Eastern Black Sea region. The data of the study is collected by having students complete the following sentences: “Science is like ……..; because ……..”, “Technology is like ……..; because ……..”, “Design is like ……..; because ……..”. In this study, which uses phenomenological research pattern within the framework of qualitative research perspective, the data obtained is analyzed through content analysis. In the research, it is seen that metaphors identified by most of the students regarding the concept of science are “space”, “ocean” and “tree”, regarding the concept of technology are “food” and “human”, regarding the concept of design is “imagination”. At the end of the study, it is found that most of the students perceive the concept of science as “infinite”, “changing and developing”, “enlightening”, “life source” and “nerve-shredding”, the concept of technology as “changing and developing”, “facilitating”, “harmful as much as beneficial” and “unlimited”, the concept of design as “imaginary”. Moreover, it is identified that metaphors produced regarding concepts of science and technology are more in numbers compared to metaphors produced regarding the concept of design.

Aim: The aim of this study was to present the sonographic characteristics of follicular variant of papillary thyroid carcinoma (FVPTC) related to different forms of the thyroid nodules, including those without a capsule. Another purpose was to analyze the color Doppler ultrasonography (CDUS) features of this unique tumor, which have not been intensively studied in previous works.Materials and Methods: Twenty-two thyroid nodules (male/female: 17/5; mean age±SD: 42±16 years; range: 17-70) diagnosed with FVPTC were included in this study. The sonographic and Doppler features of the nodules were analyzed retrospectively. The intranodular pattern of vascularity was categorized with regard to the presence of perinodular and/or intranodular vascular signals, as well as a “spoke-and-wheel” appearance.Results: The length of the nodules varied from 6 to 55 mm. Most of nodules were purely solid (77.3%), isoechoic (59.1%) or hypoechoic (31.8%) and had an oval shape (72.7%), well-defined margins (68.2%) and a peripheral hypoechoic halo (68.2%). Thirty-one percent of the nodules had a lobulated shape with microlobulated margins or an irregular configuration with ill-defined margins. Encapsulated FVPTCs had a peripheral hypoechoic halo and well-defined margins, whereas infiltrative cases exhibited the opposite characteristics. No calcification was observed in 72.7% of the nodules. Perinodular and predominantly peripheral intranodular hypervascularity was observed in 14 nodules (66.7%) and was the dominant pattern of vascularity in most of the encapsulated FVPTCs, unlike the infiltrative FVPTCs.Conclusion: Diagnosis of FVPTC should always be considered when large thyroid nodules with predominantly solid echo-texture and other sonographic features that suggest benignity and nodular hypervascularity are observe.
Evils of the Istanbul Convention. Discourse analysis of Latvian press publications (2016) = Los efectos negativos del Convenio de Estambul. Análisis del discurso de publicaciones de prensa letonas (2016)
Authors: Zitmane Marita
Published: February 2018

Abstract. The Council of Europe Convention on preventing and combating violence against women and domestic violence caused heated discussion both in society and media in Latvia. The controversy was caused because Convention is based on the understanding that violence against women is a form of gender-based violence that is committed against women because they are women. The discussion showed that there are various interpretations and misinterpretations of gender as a concept. As well as hostility towards gender equality interpreted as a propaganda against so called traditional family values. The mass media play an important role in shaping of public thought.The mass media today are the main source of information – a source which not only offers reportage about important events, but also determines the public agenda. By offering commentary on various subjects, the media construct public attitudes towards those subjects. The aim of this article is to examine how the Istanbul Convention was represented in Latvian daily newspapers, what discourses were dominating in media; what information regarding the Convention, gender and gender equality were communicated.Keywords: gender, discourse, fear, Istanbul Convention, right-wing.Resumen. El Convenio del Consejo de Europa sobre prevención y lucha contra la violencia contra las mujeres y la violencia doméstica ha generado un acalorado debate tanto en la sociedad como en los medios de comunicación de Letonia. La controversia surgió porque el Convenio parte de la premisa de que la violencia que se ejerce contra la mujer es una forma de violencia de género que se ejerce contra las mujeres por el hecho de ser mujeres. El debate puso de manifiesto que existen diversas interpretaciones, erróneas algunas de ellas, del concepto de género, así como hostilidad hacia la igualdad de género interpretada como propaganda contra los llamados valores familiares tradicionales.Los medios de comunicación desempeñan un cometido importante en la formación del pensamiento público. Hoy son la fuente principal de información; una fuente que no solo informa de acontecimientos importantes, sino que también configura la agenda pública. Al comentar diversos temas, los medios construyen actitudes públicas hacia esos temas. El objetivo de este artículo es examinar cómo se representó el Convenio de Estambul en los periódicos letones, cuáles fueron los discursos dominantes en los medios de comunicación, y qué información se comunicó con respecto al Convenio, el género y la igualdad de género.Palabras clave: género, discurso, miedo, Convenio de Estambul, ultraderecha.
Dignidad de la mujer y multiculturalismo = Dignitiy of women and multiculturalism

Resumen. Este trabajo se centra en la discusión entre multiculturalismo y feminismo, orientando la atención a las sociedades multiculturales que están llenas de prácticas y tradiciones basadas en las ideologías de género, hecho claramente destacado por investigadores sociales como María Dolors Molas Font y Susan Moller Okin, entre otros. En culturas patriarcales como la nuestra es común permitir e incluso facilitar que los hombres controlen a las mujeres, anulando así su reconocimiento de la dignidad. Según la perspectiva hegeliana del reconocimiento y entendiendo la dignidad con un matiz kantiano, se propone resolver la antinomia entre el multiculturalismo y el feminismo desde un plano educativo. Para ello, la experiencia de la maestra y etnoeducadora Laura Montoya se expone groso modo en la última parte de este trabajo.Palabras clave: multiculturalismo, dignidad de la mujer, reconocimiento, educación, Laura Montoya.Abstract.

An Impressive Array of New Books
Authors: Desmarais Robert
Published: February 2018

Dear Readers,I am so grateful for the hard work and commitment of our Deakin reviewers, and I think you will share my enthusiasm for the books that they have written about for our winter issue. For example, Leslie Aitken’s review of Lila and the Crow is a wonderfully thoughtful appraisal of an important picture book deserving of a good deal of attention. Aitken writes that “Lila and the Crow belongs in every elementary school library” and I wholeheartedly agree with her assessment because this story has excellent potential to encourage positive dialogue about the physical diversity of humankind.Another highly recommended picture book is Anna Pingo’s Aluniq: and Her Friend, Buster, reviewed by Sandy Campbell. As Aluniq’s story of living with her grandparents at the Qunngilaat Reindeer Station in Canada’s Northwest Territories unfolds, readers learn that many families in remote parts of Canada experience separation when people need to leave home to receive medical treatment. The emotions that this poignant story conveys are generally ones that resonate with most readers because they remind us of one of the most significant primal fears of childhood—separation from one’s parents or guardians. For young readers coming to terms with separation, this is a charmingly illustrated and sparingly written picture book. I therefore commend it to your serious attention.Also in this issue, Lorisia MacLeod’s review of How Nivi Got Her Names calls our attention to Inuit naming customs and provides useful content for educators who want to discuss Inuit culture with young readers in the classroom.Plus, we have adventure stories, historical stories, and engaging stories of childhood and family life. Enjoy!Robert DesmaraisManaging Editor
Little Blue Chair by C. Fagan
Authors: Aitken Leslie
Published: February 2018

Fagan, Cary. Little Blue Chair, illustrated by Madeline Kloepper.  Tundra Books-Random House Canada, 2017.Cary Fagan has created many delightful picture books, among them, Ten Old Men and a Mouse, illustrated by Gary Clement (2007); Mr. Zinger’s Hat, illustrated by Dušan Petričić (2012); and A Cage Went in Search of a Bird, illustrated by Banafsheh Erfanian (2017). In each of these works, the illustrator has brilliantly conveyed the sense of the text.The storyline of Little Blue Chair would appear to have much potential for robust illustration. Fagan creates the classic circular journey. A little blue chair, outgrown by its initial child owner, is repeatedly given away, used for a time, and given away again. It serves, by turns, as a plant stand, a seat in a wheel house for a sea captain’s daughter, a howdah for children who want elephant rides, a bird feeder in a garden, a seat on a carnival Ferris wheel, and, finally, an air borne craft powered by balloons which carry it back to its original owner. The illustrations, however, are not quite as adventurous as the story.Whether by the artist’s intent, or the printer’s choice, the colour palette is muted. The choice works well for creating the ambiance of the “junk shop” [p.5], and is, arguably, appropriate for the seascapes [p.7-10], but it seems subdued for the carnival scenes [pp. 21-24].A further problem arises where the expectations raised by the story are not met by the artwork. Surely some glorious avian display should support the following text:          From all around, birds appeared in the air. Little birds, big birds, plain birds and fancy birds—they all perched on the chair to eat the seeds.” [p.18] In fact, “the air” and “the chair” are devoid of any birds, and the few tiny ones perched in a tree are barely distinguishable because of the muted colours.A similar problem occurs in the Ferris wheel scene. Fagan writes: “The man installed the little blue chair. Up, up it went. Round, round it went! The children screamed with pleasure.“We see just a portion of the Ferris wheel—a few seats, one of which can be discerned as the little blue chair. There are three child passengers; two look vaguely pleased, one seems distracted by her candy floss. We cannot detect a single open mouth that might be indicative of a scream of pleasure.Young children who are not yet independent readers rely on illustration to convey the action, context and mood of their picture books—thus, the vital need for a “happy marriage” of text and illustration. Little Blue Chair seems to offer just a tentative courtship. Recommended with Reservations: 2 out of 4 starsReviewer: Leslie AitkenLeslie Aitken’s long career in librarianship included selection of children’s literature for school, public, special and academic libraries.

Published: February 2018

Robertson, Joanne. The Water Walker. Second Story Press, 2017.The Water Walker is the true story Nokomis (grandmother in Ojibwe) Josephine Mandamin, the founder of the Mother Earth Water Walkers. Nokomis and the Water Walkers’ goal is show how precious nibi (water) is to our very survival, and to ensure it is properly protected and cared for.Nokomis had always been thankful for nibi, but feels compelled to act when an ogimaa (a leader or chief) told her that one day “... an ounce of water will cost more than an ounce of gold.” What was Nokomis going to do about it? Gathering relations, friends, and community members, they form the Mother Earth Water Walkers, with the goal to protect and honour nibi. Between 2003 and 2009, the Water Walkers walk around the Great Lakes and the St. Lawrence River, carrying a copper bucket of water and a bald eagle staff as they went. The Water Walkers expand their call, walking water from the Pacific, Atlantic, Arctic, and Gulf of Mexico. At the end of the book, while Nokomis rests after her all walking, she wonders what are you going to do about protecting nibi?This is an accessible and relevant story appropriate for both early and mid-elementary school children. Younger children will appreciate the vibrant illustrations, while older children will connect with the environmental message of the book. Ojibwe words are used throughout, and there is a detailed glossary and pronunciation guide to assist readers. Finally, there is contact information for Josephine Mandamin, so readers can share with her how they are conserving and protecting water. This book would do well in both public and school libraries. Recommended: 3 out of 4 starsReviewer: Andrea QuaiattiniAndrea Quaiattini is a Public Services Librarian at the University of Alberta’s JW Scott Health Sciences Library.

How Nivi Got Her Names by L. Deal
Authors: MacLeod Lorisia
Published: February 2018

Deal, Laura. How Nivi Got Her Names. Illus. Charlene Chua.  Inhabit Media, 2017.Inhabit Media, an Inuit-owned publishing company, has brought to publication another wonderful story celebrating Inuit naming customs and family ties in How Nivi Got Her Names. The story follows young Nivi as she asks her mother how she came to have the names that she has which leads to an explanation of the traditional Inuit naming practices. The introduction by Aviaq Johnston features some basic information into the cultural background surrounding Inuit custom adoption and naming which would be useful to both adults reading to children and educators looking to frame this book within a lesson plan on Inuit ways of life. Similarly, the glossary featured at the end of the book provides readers with aid in translating the various traditional kinship terms that are used throughout the story.It features 32 pages of full-colour illustrations, all of which are vibrant and provide visual interest for readers while the writing is always on a white background to ensure good readability. The text overall is simple and comprehensible to the intended audience of 5 to 7 year-olds, but may be above their reading level, so an adult may need to read this book aloud. For parents, this book could be a great springboard into discussing family stories with their child. For educators and public librarians, this book is a very accessible introduction to a facet of Inuit culture that could easily be used during reading times or in the classroom.Highly recommended: 4 stars out of 4Lorisia MacLeod is a second year Masters of Library and Information Studies student and Indigenous Intern at the University of Alberta.

Food Atlas: Discover All the Delicious Foods of the World by G. Malerba
Authors: Distad Merrill
Published: February 2018

Malerba, Giulia. Food Atlas: Discover All the Delicious Foods of the World, illustrated by Febe Sillani, translated by Sharon Morin. Firefly Books, 2017.This large and beautiful folio volume provides an agricultural and culinary tour of the world in the form of nearly fifty maps that cover six continents, Oceania, and fifty individual countries. The book ends with a two-page map of the world to illustrate the “food journeys” by which many familiar, staple foods were transplanted around the globe. Luca Mingolia’s maps, overlain with Febe Sillani’s hundreds of colourful illustrations, depict both the characteristic foods and ethnic dishes of each country and region. The coverage is extraordinarily comprehensive, ranging from Sweden’s repugnant-smelling Surströmming to the equally pungent Durians of southeast Asia, and from Egyptian Ful Medames to India’s Gulab Jamun.Although cast in the format of a book for older children, this fascinating volume is one from which older readers, including adults, may take pleasure and expand their culinary horizons.Highly Recommended: 4 out of 4 starsReviewer: Merrill DistadHistorian and author Merrill Distad enjoyed a four-decade career building libraries and library collections.

O Império Britânico e a redescoberta do Antigo Egito: a coleção de antiguidades ￼
Authors: Eggers Natascha de Andrade
Published: February 2018

Por meio da análise do diário de viagem do antiquarista Giovanni Belzoni, temos como principal objetivo compreender como o estudo da civilização egípcia antiga e de sua cultura material foi essencial para a construção de uma memória nacional britânica durante o século XIX. Com base nesse documento, iremos nos ater a três eixos temáticos: como o Antigo Egito e sua cultura material estão sendo representados por essa fonte; de que forma a presença britânica no Egito é justificada pelo mesmo documento; como seu discurso estabelece uma ideia de herança cultural com o passado antigo, influenciando a formação de museus nacionais e, também, na gênese da Egiptologia e da Arqueologia enquanto ciências e atividades profissionais.
Ascertaining the Sense of Safety in Urban Neighborhood Streets: The Case of Kotahena, Sri Lanka
Authors: Karunananda Sanduni , Rajapakse Amanda , Rathnayake Rangajeewa
Published: February 2018

Streets are primary elements through which the character of urban neighborhoods are experienced and expressed. The “sense of safety” in neighborhood streets is paramount to social and psychological wellbeing of its residents and visitors. The intention of this study was to explore environmental and social cues of a neighborhood, which evoke fear of crime, which will help designers to prevent the generation of such negative feelings and promote more safe and comfortable spaces in our cities. This study used interviews, group discussions and observations to identify fear-generating factors with a sample of participants in the multi ethnic neighborhood of Kotahena in Colombo, Sri Lanka. Field data was analyzed through visual documentation and photographic surveys. Moreover, group discussions, interviews and personal observations were used to synergize the study objectives. The findings inform that fear of crime on streets is influenced by both environmental and social cues to varying degrees. Feelings of fear were associated with gender, ethnicity and less familiarity with the place as participants were from an ethnic minority within the community. Literature has emphasized that fear of crime has a connection to actual crime locations. The research findings, however, indicate that fear of crime spots identified by the residents do not have a direct relationship to the actual crime locations.
Investigating the Role of Shape and Size of Gold Nanoparticles on Their Toxicities to Fungi
Authors: Liu Kangze , He Zhonglei , Byrne Hugh J. , Curtin James , Tian Furong
Published: February 2018

The possibility of releasing gold nanoparticles (GNP) into the environment has been rapidly increasing with the wide spread and flourishing application of gold nanoparticles (GNPs) in a wide range of areas. Consequently, environmental effects of GNP, especially toxicities to living organisms have drawn great attention. However, their toxicological characteristics still remain unclear. Fungi, as the decomposers of the ecosystem, interact directly with the environment and critically control the overall health of the biosphere. Thus, their sensitivity to GNP toxicity is particularly important. The aim of this study was to evaluate the role of shape and size of GNPs on their toxicities to fungi, which could help reveal the ecotoxicity of GNPs. Aspergillus niger, Mucor hiemalis and Penicillium chrysogenum were chosen for toxicity assessment, and circular and star/flower-shaped GNPs sized from 0.7 nm to large aggregates of 400 nm have been synthesised. After mixed with GNPs and reacting agents of GNPs accordingly and incubated for 48 hours, the relative survival rates of each kind of fungus was calculated and compared. The results indicated that with similar sizes, star/flower-shaped GNPs are more toxic to fungi than circular-shaped GNPs; the toxicity of star/flower-shaped GNPs increases with smaller sizes. The results also showed that different species of fungus reacts differently to same GNPs, and Penicillium chrysogenum was relatively more sensitive under the exposure to GNPs.

A methodology for both accurate and smooth contour line generation from Light Detection and Ranging (LiDAR) point clouds is proposed in this paper. In order to improve the accuracy of contour lines in the area of forests, constrained triangulation networks with break lines are then constructed to generate contour lines. In break line extraction, a bi-threshold method for edge line detection is used to extract both complete and reliable break lines. A point clouds elevation adjustment with constrain of break lines and an interpolator considering a contour interval is proposed to improve the smoothness of contour lines. The proposed interpotator is also can avoid contour line intersection when contour lines are interpolated. Statistical parameters and shape index are then used to evaluate quantitatively the accuracy and smoothness of the resultant contour lines, which fill in the blank of contour lines evaluation in theory. The experiments show that high-quality contours in terms of smoothness and accuracy can be generated from LiDAR point clouds.

More than 100 billion lbm of proppant are placed annually in wells across the globe, with the majority in unconventional reservoirs. The location of the proppant in these horizontal wells and formations is critical to understanding reservoir drainage, well spacing, and stage spacing. However, for many years proppant detection has primarily been limited to near-wellbore measurements. A novel method to detect proppant in the far field has been developed and is the subject of this paper.

The proppant-detection method developed uses electromagnetic (EM) methods. This technology entails using a transmitter source and an array of electric- and magnetic-field sensors at the surface. A current signal with a unique wave form and frequency is transmitted to the bottom of the wellbore via a standard electric-line (E-line) unit. In addition, an electrically conductive proppant is pumped into the stage(s) of interest. The electric and magnetic fields are measured both before and after the detectable proppant stages, and a novel analysis method is then used to process and invert these differenced data to create an image of the propped reservoir volume (PRV).

This technology is the product of years of development of computer models capable of forward modeling this technique. Once this modeling was completed, an initial field test was performed in west Texas (WTX), with a preliminary analysis of this work presented in a previous paper (Palisch et al. 2016). Since that paper, however, additional processing of the data has yielded a much-more-detailed image of the proppant location in this Bone Springs well. In addition, a subsequent field application has been performed in a major basin in the northeastern US. Multiple stages received detectable proppant of varying stage volumes, and the analysis has also shown a detailed image of the proppant location in that wellbore. Furthermore, the initial field test in WTX used only electric-field sensors, whereas this latest test used both electric- and magnetic-field receivers. The authors’ numerical simulations coupled with the field results indicate the percentage difference between prefracture and post-fracture results is two times higher using magnetic- vs. electric-field sensors.

This paper will review the technology development and methods, will present the latest imaging from the initial WTX test, and will describe the latest learnings from the most-recent field test. This paper should be beneficial to all completions and development personnel who are interested in knowing where proppant is in their fractures. This technology has the potential to assist in understanding well drainage and spacing, stage and perforation-cluster spacing, vertical fracture coverage, and the effect of fracture-design changes.
Capillary Desaturation Curve for Residual Nonwetting Phase in Natural Fractures
Authors: AlQuaimi B. I. , Rossen W. R.
Published: February 2018

The displacement of a nonwetting phase by a wetting phase is characterized by the capillary number. Different forms of capillary number have been used in the literature for flow in porous media. A capillary number for a single rock fracture has been defined in the literature, using the mean aperture to characterize the trapping and mobilization in a fracture.

We propose a new capillary-number definition for fractures that incorporates geometrical characterization of the fracture, dependent on the force balance on a trapped ganglion. The new definition is validated with laboratory experiments using five distinctive model fractures. The model fractures are made of glass plates, with a wide variety of hydraulic apertures, degrees of roughness, and correlation lengths of the roughness. The fracture surfaces were characterized in detail and statistically analyzed. The aperture distribution of each model fracture was represented as a 2D network of pore bodies connected by throats. The hydraulic aperture of each model fracture was measured experimentally. Capillary desaturation curves (CDCs) were generated experimentally using water/air in forced imbibition. The transparent nature of the system permits us to determine the residual air saturation as a function of pressure gradient from the captured images.

The residual nonwetting saturation/capillary-number relationship obtained from different fractures varying in aperture and roughness can be represented approximately by a single curve in terms of the new definition of the capillary number. They do not fit a single trend using the conventional definition of the capillary number.

Para assegurar a sustentabilidade do sistema via úmido de processamento do Coffea arabica L., é necessário que o resíduo líquido proveniente da lavagem e, principalmente, do descascamento seja tratado corretamente. Assim, o objetivo deste trabalho é avaliar a eficiência do tratamento de águas residuárias do processamento de café cereja descascado, através do método das lagoas anaeróbicas e facultativas, de fácil construção, manejo e eficiência. Foi comprovado que a eficiência da metodologia, considerando que para a produção de uma saca de café de 60 kg, com volume aproximado de 480 L de fruto, pode consumir no sistema tradicional cerca de 2.400 L de água, enquanto que pelo sistema de tratamento das águas residuárias este número é reduzido pela metade, podendo chegar a apenas 0,5 L de água por litro de fruto produzido. Este método fornece ainda melhorias através do controle de demanda bioquímica do oxigênio (DBO), evitando o aparecimento das macrófitas e permitindo o controle e a manutenção de um sistema oligotrófico tanto à montante quanto à jusante das lagoas.

Bacteriocins are antibacterial, mainly complex, substances of protein nature. The promising strains producing bacteriocins used in the food industry are lactic acid microorganisms. This study examines the development of a technology for the production of a recombinant peptide with broad-spectrum antimicrobial properties. An important step is the isolation and purification of the recombinant peptide. It has been proved that the highest antimicrobial activity is manifested by a recombinant peptide isolated by a method based on salting out with ammonium sulfate. During the purification of the recombinant bacteriocin preparation, three kinds of columns were used. In the purification process, the volume of bacteriocin produced decreases 3-fold, while the RU/mL increases 3-fold, and RU/mg increases 6-fold. Purification allows the use of a smaller amount of recombinant bacteriocin in technologies with greater efficacy. Based on the results of determining the molecular weight and purity of the recombinant bacteriocin, it was found that the molecular weight of the recombinant bacteriocin having the amino acid sequence: KYYGNGVTCCKHSCSVDXGKASSCIINNGAMAXATGGH GGNHCCGMSRYIQGIPDFLRGYLHGISSANKHKKGRL, is 13 kDa. A technology for the preparation of a broad-action antimicrobial spectrum peptide has been developed. The process of production of antimicrobial peptide includes such stages as: cultivation of the recombinant strain of Escherichia coli BL21DE3; separation of biomass from the nutrient medium; precipitation of bacteriocins by ammonium sulfate; centrifugation; washing the precipitate; centrifugation at 4200 rpm and separation of the preparation; purification of bacteriocins by HPLC method; packing in bags of polymeric and combined materials; storage at a temperature of 18±2°C for 12 months.

The present paper illustrates the results of the study on chromatographic behavior and optimization of some parameters of the method of quantitative determination of bornyl acetate and isobornyl acetate diastereomers under the conditions of reversed-phase high- performance liquid chromatography. Chromatography was performed with HPLC platform Agilent 1200 with diode-matrix detector and a column Agilent Zorbax XDB, Extend-C18. Detection of the studied analytes was performed at a wavelength of 210 nm. Determinationof the concentration of bornyl acetate isomers was carried out in mixture with other components of the Abiessibirica essential oil in chromatographic systems with mobile phases of acetonitrile-water or isopropyl alcohol-water. The range of analyte concentrations in a sample was varied from 2 to 430 mg/ml for bornyl acetate and from 2 to 950 mg/ml for isobornyl acetate. It is stated that in a chromatographic system with a mobile phase, based on acetonitrile, the peaks of the studied components have an asymmetric shape, and the retention times of analytes increase with the decrease of their concentrations in a sample. In a chromatographic system with isopropyl alcohol the asymmetry of the bornyl acetate peak disappears, the width decreases and the retention time stabilizes. For isobornyl acetate a peak width also decreases, its asymmetry is preserved, but at the same time, the asymmetry coefficient takes on permitted values (less than 2). Calibration charts for the mentioned compounds in the used eluents are linear throughout the studiedconcentration range with correlation coefficients of R2>0.998. Thus, the conducted researches allow to recommend the reversed-phaseHPLC variant for the separate quantitative determination of bornyl acetate and isobornyl acetate in the pine oil samples.
