Para além da palavra: multissemiose e hibridismo na urdidura do ciberpoema
Authors: Martins Dias Anair Valênia , Tibúrcio Fábio
Published: March 2018

O presente artigo tem como objetivo principal discutir o gênero discursivo multissemiótico ciberpoema. Para tanto, propõe-se um percurso histórico para o entendimento da migração da poesia visual para o espaço virtual. Observa-se o abandono de alguns elementos estruturais da poesia canônica em detrimento de uma poesia (re)configurada num processo virtual e multissemiótico, no qual a materialidade plástica do texto vai além da palavra escrita e seu conteúdo semântico. São analisados três ciberpoemas de Augusto de Campos – Criptocardiograma, Semsaída e ininstante, bem como o ciberpoema Poemas no meio do caminho, de Rui Torres e Worthy Mouths, de Maria Mencia. Depreende-se, então, que o poeta, utilizando-se das tecnologias digitais, arrebanha no espaço virtual a integração simultânea da palavra, do movimento, do som, da imagem, a partir do momento que convoca a intervenção lúdica e inteligente do leitor para a composição e a construção de múltiplos significados a serem extraídos do ciberpoema.
Os poetas como agentes de tradução: Uma análise a partir das antologias de poesia brasileira em tradução para o castelhano
Authors: Lázaro Igoa Rosario
Published: March 2018

O presente artigo releva e analisa os tradutores das quase quarenta antologias de poesia brasileira em tradução para o castelhano desde 1912 até hoje. Retomando um relevamento de corpus já publicado (LÁZARO, 2014), esse desdobramento da pesquisa procura abordar a figura dos tradutores nas “antologias de tradução” (FRANK & ESSMANN, 1990; ESSMANN & FRANK, 1991) de poesia entre o Brasil e a América Hispânica. Partimos da hipótese de que entre sistemas e gêneros literários não centrais, a relevância intercultural destes “agentes de tradução” (MILTON & BANDIA, 2009) deve ser abordada como força alternativa aos interesses meramente editoriais. Desta forma, analisam-se os perfis dos tradutores, assim como pretende-se demostrar a comum associação entre as tarefas de organizador e tradutor neste tipo de obras, levadas adiante frequentemente por poetas. Por fim, o artigo ressalta o papel dos programas e iniciativas de fomento à tradução de literatura brasileira nestas antologias.

Muistisairas ihminen liikenteessä
Authors: Nikumaa Henna , Mäki-Petäjä-Leinonen Anna
Published: March 2018

Ikääntyvien kuljettajien määrän lisääntyessä myös muistisairaiden ihmisten osuus ajokortin haltijoissa kasvaa. Artikkelissa tarkastellaan etenevää muistisairautta sairastavan ihmisen ajo-oikeutta hyödyntäen lainopin menetelmiä. Vaikka muistisairaus johtaa edetessään ajokortista luopumiseen, ei pelkkä diagnoosi sairauden lievässä vaiheessa tarkoita ajoluvan menettämistä kaikissa ajokorttiryhmissä. Onnettomuusriski kasvaa sairauden edetessä, mutta yksilölliset erot voivat olla merkittäviä, ja ajokyvyn arvioinnissa tulee kiinnittää huomiota muistisairaan kokonaistilanteeseen. Oikeus ajoneuvon kuljettamiseen on usein keskeinen osa sairastuneen identiteettiä ja osa hänen autonomiansa toteutumista. Ajo-oikeuden poistaminen voi kuitenkin olla välttämätöntä paitsi sairastuneen itsensä suojaamiseksi myös muiden turvallisuuden takaamiseksi. Artikkelin lopuksi pohditaan ratkaisuja muistisairaan ihmisen liikkumisen turvaamiseksi. Tutustuminen vaihtoehtoisiin ja turvallisiin liikkumisen keinoihin tulisi aloittaa riittävän ajoissa. Rajoitetun ajo-oikeuden mahdollisuutta tulisi edelleen maassamme selvittää erityisesti syrjäseuduilla asuvien varhaisvaiheen muistisairaiden näkökulmasta. Lisäksi muistisairaille ihmisille tulee taata muiden sairaus- ja vammaryhmien tavoin yhdenvertainen oikeus vammaispalvelulain nojalla myönnettäviin kuljetuspalveluihin.

People with dementia in traffic

As the number of older drivers increases, so too does the number of people with dementia who hold driving licences. In the course of the disease’s progress, the capacity to drive diminishes and is at some point inevitably lost. This article examines how dementia affects an individual’s driving ability and how elderly people and people with dementia are taken into account in the legislation governing driving licences. The article also assesses the issue of the autonomy enjoyed by a driver and the importance of a driving licence for people with dementia. Finally, the article offers solutions aimed at safeguarding the right to liberty of movement and transportation for people with dementia so that they can live independently and participate fully in all aspects of life. People with dementia should be treated in the same way as those who have other types of illness and those who fall within other disability groups and be guaranteed equal access to transport services under the Disability Services Act.

The popularity of numerical methods for modeling soil bases determines the increased demand for the accuracy of calculations. The choice of a model that meets the requirements of accuracy of calculations and minimization of costs is determined by comparative analysis of common soil models described in scientific literature and used in calculations of sediments and dynamic effects of buildings (finite element linear elastic, elastic, ideal-plastic, Mora - Coulomb with strengthening, elasto-plastic with strengthening at small deformation). The results have been obtained on test models using finite element method in the environment of PLAXIS 3D and SCAD Office programs. In order to compare results obtained, subject to requirements of the current regulatory documents, a comparative analysis of soils was carried out according to the model of Body of rules 22.13330.2011 "Foundations of buildings and structures". The analysis results were used for choosing an optimal model of soil bases of industrial buildings estimated in earthquake-proof design. It should be noted that the strong and weak points identified for each model justify the choice of the best model for each particular case.

Published: March 2018

Modern tendencies of development of world and domestic oil and gas processing involve deep processing of heavy oil and condensate residues for the production of motor fuels and other petroleum products and minimizing the production of energy boiler fuel. Modern technological processes of deep recycling of oil and gas condensate residues are conventionally divided into four large groups: direct processes consisting of one main standard process; combined processes consisting of two or more interconnected generally used refining processes including possible pre-refining of raw materials; processes using slurry reactors and reactors with a suspension catalyst bed for nanoheterogeneous catalysis; processes of deep processing of hydrocarbonic residues using wave impacts. Processes of the first group are most widely used in industry, combined processes of the second group are used much less often. After successful completion of pilot testing processes of the third group (slurry technology and nanoheterogeneous catalysis) are much forward-looking. The process of the fourth group can become promising for industrial implementation only after experimental analysis of their actual energy efficiency.

Authors: Popov Georgiy Aleksandrovich , Avtaev Vladimir Andreevich , Romanenko Nikolay Gennadievich
Published: March 2018

The purpose of the study is the development of the air conditioning system (ACS) that can perform not only basic functions maintaining most optimal human values of temperature, humidity and other environmental characteristics, inherent in standard ACS, but also act as a part of a complex life safety system for most possible factors. Such factors are biological and chemical threats, fire safety, physical and vibroacoustic effects, etc. There has been carried out the analysis of the types of air conditioners and the requirements imposed on them, as well as factors that could affect the functioning of ACS. The basic requirements for ACS as a security system have been developed. The functional scheme of ACS was formed on the basis of a block diagram, which included additional functions. There has been considered the possibility of using inhalation as a preventive measure against infectious and virus diseases and as an inhaler spray. A set of sensors necessary to monitor the room environment have been described. The results of the research can be used to build a universal ACS with enriched functionality: from regulating the temperature and humidity parameters to monitoring the room environment and maintaining the safety of the facility.
RELATIONS FOR CHARACTERISTICS OF MULTI-CHANNEL SYSTEMS WITH POISSON ACCIDENTS
Authors: Popov Georgiy Aleksandrovich
Published: March 2018

The article describes a special class of multichannel systems with Poisson incoming flows. The assumption of poissonity of the incoming flow is typical for many models. For these systems there are found recurrent relations for Laplace-Styltjes transformations of joint distribution of the queue lengths, residual time of services and a busy period, which allow to express these characteristics through their marginal values: joint distribution of residual services and a busy period at the moment of the beginning of services and in the moments of calling-in, when the system has no queue, or rather, not all devices are busy. Thus, the problem of analysis of multi-channel systems with Poisson incoming flows is reduced to the problem of finding marginal characteristics of the specified system. All other system characteristics can be expressed through the described characteristics of the system. For every moment of the service beginning there is introduced a parameter: the vector of the numbers of servicing devices, components of which are arranged in the increasing order of residual duration of service on the respective devices - the vector of order release devices. The obtained system of integral relations, linking the system characteristics of all vectors of the order of release of the devices among themselves.
INFLUENCE OF THE ENVIRONMENTAL FACTORS ON SHEATFISH FISHING IN THE VOLGA-CASPIAN AND THE NORTH-CASPIAN FISHERY SUBAREAS
Authors: Kolosyuk Gennadij Grigor'evich , Nikiforov Sergey Yurievich
Published: March 2018

Delta and delta front of the Volga river are the main fishing areas in the Astrakhan region, which provide high fish capacity. At the same time, productiveness of fishing in these areas is extremely unstable because they are effected by numerous environmental factors. The essential factor is changing the level of the Caspian Sea, which is directly related to hydraulicity of the Volga watershed. Sea-level change results in changing the area of shallow water zone and coast line, which strongly impacts on a previous biotope. Besides changing the sea level and the volume of fresh-water flowing, water bio-resources are influenced by the volume of spring flood, terms of the flood beginning and thermal regime in the region. Interference of all these factors impacts on stock forming and on fishing of all fish species caught in this region. But this interference of different fish groups (semi-anadromous, river, non-migratory) is ambiguous, which is related with their biology. The purpose of the research is to define the influence of these factors on fishing one of the most important commercial fish species - sheatfish ( Silurus glanis ). The analysis of the available materials has shown that sheatfish catches in a great degree depend on some abiotic factors. Thus, raising the sea level leads to the decrease of sheatfish catches, and increasing of water mass during the flooding period in the Volga river results in lowering the total catch. Later beginning of the flood period improves the effectiveness of fishing, as well as early warning-up of water.
WAYS TO MANAGE ELEMENTS OF FISHERIES MANAGEMENT SYSTEMS AND FISHERIES MANAGEMENT PROCESSES
Authors: Bozhko Andrey Petrovich , Pogozhev Oleg Aleksandrovich , Melnikov Alexander Victorovich
Published: March 2018

The management of fishery systems provides for the management of aquatic organisms aimed at changing their position and (or) the degree of mobility in order to increase the efficiency of a particular fishery process, and management of the fishery to ensure that the catching object falls into the catching zone, as well as to decrease probability of his withdrawal from this zone. It is shown that the management of hydrobionts differs: by the way information is transmitted and its biological effectiveness; types and operation principles of the control systems; biological significance of external influence; reaction to the stimulus; selectivity of management, etc. The features of each control option are described. Methods of assessing the features of management of elements of fishery systems are considered, taking into account the information approach. Management is used at the different stages of the fishery process: at various stages of fishing, forming schools of commercial hydrobionts and so on. The paper describes some aspects of applying adaptive management methods to fisheries processes in connection with a high degree of uncertainty of the initial data and of the system condition. The principle of functioning of such systems of process control is the gradual accumulation and use of information to achieve some optimal state and behavior of the system in the light of initial uncertainty, e.g. changing external conditions. Control systems of this type are adapted in the process of adjustment and operation. In the course of such adaptation the coefficients, parameters and structure of the system usually change, in some cases the algorithm of functioning, control actions, etc. change too.

Religious and Cultural Existences Within the Communities of Upper Kapuas Riverside of West Kalimantan
Authors: Prasojo Zaenuddin Hudi
Published: March 2018

The sudies on the issues related to communities in the interior of West Kalimantan begin to take place when Dutch and other European scholars in the colonial period came to the region. But they have been limitedly documented. The amount of research by local and foreign scholars in the region is still not significant when compared to that of research in Sarawak, Sabah and Brunei which are also situated on the island of Borneo. In fact, the natural wealth, cultural heritage and the rural communities of West Kalimantan need serious attention and studies for the purpose of the development of the region. In addition, local elements such as human and cutural resources may become potential supports of development to improve the welfare of the communities. This study highlights the significant contribution of religious and cultural aspects within the communities living around the upper Kapuas riverside. Acculturation of local and Islamic cultures have occurred since the advent of Islam into the interior areas of Kalimantan through the Kapuas River. The acculturation of local religions and cultures also promotes a very important local religious institution in the process of social change of the communities of the Kapuas riverside in the interior of West Kalimantan. The local religious institutions serve as an infrastructure that has been proven to ensure the survival of the living Muslim community system that existed among indigenous people who were still in the local beliefs of their time. This study also finds that the Muslim communities of the Kapuas Riverside in the interior of West Kalimantan already have extensive networks, not just the kinship network, Islamic trade and da'wah but also the network of scholarship. Of course, the growth of these growing networks is influenced by the media that also develops in its name. Thus this work also describes a comprehensive analysis of cultural and religious aspects in the development of communities of the Kapuas riverside in the interior of West Kalimantan which is currently included in the administrative areas of Sintang and Kapuas Hulu Districts.

Published: March 2018

OBJECTIVE To evaluate in vitro phagocytosis and bactericidal activity of circulating blood neutrophils in horses with severe equine asthma and control horses and to determine whether circulating blood neutrophils in horses with severe equine asthma have an increase in expression of the proinflammatory cytokine tumor necrosis factor (TNF)-α and the chemokine interleukin (IL)-8 and a decrease in expression of the anti-inflammatory cytokine IL-10 in response to bacteria.

ANIMALS 6 horses with severe equine asthma and 6 control horses.

PROCEDURES Circulating blood neutrophils were isolated from horses with severe equine asthma and control horses. Phagocytosis was evaluated by use of flow cytometry. Bactericidal activity of circulating blood neutrophils was assessed by use of Streptococcus equi and Streptococcus zooepidemicus as targets, whereas the cytokine mRNA response was assessed by use of a quantitative PCR assay.

RESULTS Circulating blood neutrophils from horses with severe equine asthma had significantly lower bactericidal activity toward S zooepidemicus but not toward S equi, compared with results for control horses. Phagocytosis and mRNA expression of TNF-α, IL-8, and IL-10 were not different between groups.

CONCLUSIONS AND CLINCAL RELEVANCE Impairment of bactericidal activity of circulating blood neutrophils in horses with severe equine asthma could contribute to an increased susceptibility to infections.

OBJECTIVE To assess effects of photobiomodulation, silver sulfadiazine, and a topical antimicrobial product for the treatment of experimentally induced full-thickness skin wounds in green iguanas (Iguana iguana).

ANIMALS 16 healthy subadult green iguanas.

PROCEDURES Iguanas were anesthetized, and three 5-mm cutaneous biopsy specimens were obtained from each iguana (day 0). Iguanas were randomly assigned to 2 treatment groups, each of which had a control treatment. Wounds in the topical treatment group received silver sulfadiazine, a topical antimicrobial product, or no treatment. Wounds in the laser treatment group received treatment with a class 4 laser at 5 or 10 J/cm2 or no treatment. Wound measurements were obtained daily for 14 days. Iguanas were euthanized, and treatment sites were evaluated microscopically to detect ulceration, bacterial contamination, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity.

RESULTS On day 14, wounds treated with a laser at 10 J/cm2 were significantly smaller than those treated with silver sulfadiazine, but there were no other significant differences among treatments. Histologically, there were no significant differences in ulceration, bacterial infection, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity among treatments.

CONCLUSIONS AND CLINICAL RELEVANCE Photobiomodulation at 10 J/cm2 appeared to be a safe treatment that was tolerated well by green iguanas, but it did not result in substantial improvement in histologic evidence of wound healing, compared with results for other treatments or no treatment.

Uso de parâmetros geotécnicos como indicadores da erodibilidade de solos
Authors: Ferreira Oliveira Felipe
Published: March 2018

Processos erosivos têm-se mostrado eficazes modificadores da paisagem e, dessa forma, têm sido objeto de estudo de diversas áreas do conhecimento, tais como a geografia e a geotecnia. Assim, a literatura apresenta diversas propostas de correlações entre características intrínsecas dos solos e a susceptibilidade dos mesmos à erosão, as quais poderiam auxiliar na identificação e previsão de áreas mais propensas à ocorrência de tais processos. O estudo tem como objetivo analisar as adequabilidades e representatividades de algumas dessas correlações. Amostras de dois solos selecionadas com base nas feições erosivas que apresentavam em campo foram submetidas a ensaios de laboratório, a fim de determinar alguns dos parâmetros geotécnicos apontados na literatura como indicadores da erodibilidade. Dessa forma, podem-se verificar quais correlações são satisfatoriamente representativas dos comportamentos que os solos apresentam em campo. Os resultados encontrados apontam que os diferentes critérios sugeridos na literatura apresentam, muitas vezes, divergências entre si e em relação ao observado in loco, o que deixa evidente que os mesmos ainda apresentam limitações e requerem muito cuidado quanto às suas utilizações.

With the increased focus on community engagement in higher education, engineering faculty members are using Learning through Service (LTS) as a viable way of providing a platform for interactive participatory student learning and involvement in the community. By engaging students to learn in the community, the creation of knowledge shifts from the classroom to the community. This paper explores how LTS engineering practitioners from a diverse range of institutions use LTS to engage community partners in the co-creation of knowledge. Twenty-seven interviews were conducted with these faculty members to identify best practices for mutually beneficial partnership with the communities they serve. Analysis of the interview transcripts reveals six guiding principles of effective and sustainable community partnerships: 1) understand the needs of the community, 2) seek community feedback through direct interaction, 3) engage community partners from an asset-based viewpoint, 4) use cultural intermediaries in international LTS efforts, 5) deliver useful projects, and 6) sustain long-term relationships to improve project outcomes.

Published: March 2018

Among stove developers and implementers it has now become common knowledge that it is possible to reduce the amount of fuel, emissions, indoor air pollutants and greenhouse gases produced by traditional cookstoves through introducing improved cookstoves. However, improved cookstove effectiveness has not yet translated into an increase in the health and wellbeing of cookstove users. For this reason, the Kitchen2.0 team set out to investigate an alternative approach to solving the global health impacts of poor indoor air quality due to the use of biomass as cookstove fuel: ventilation. To better understand the role ventilation plays in kitchens with fires and cookstoves, a three-pronged approach was used, including global community surveys, a full-scale physical model, and a computational model.  Field agents affiliated with Michigan Technological University helped complete surveys on cooking habits and structures worldwide. Physical testing was conducted in the Kitchen2.0 modular kitchen by running cooking tests with different kitchen structure configurations and stoves. The computational model was developed to simplify the testing of cooking scenarios. Ventilation was found to make a significant difference on the indoor air quality of the cooking environment, reducing carbon monoxide and very small particulate matter by about 50%.  While improved cookstoves also improved air quality when paired with ventilation, they worsened air quality 10-30% when used without ventilation. The improved understanding of the impacts of ventilation could help community-based organizations improve indoor air quality, and the lives of billions worldwide.

This paper examines the authors’ experience with a small scale, community level development project and the challenges of working with a network of institutions. Small-scale development projects are supported by a network of institutions that are essential to project success but create an inherent level of complication that may be daunting to student-based humanitarian organizations. Through a thorough examination of this institutional system, its complexity, and mechanisms which can lead to a project failure, this paper contributes to the knowledge base available to the development community. First presented is the background and development of a University of Idaho Student Chapter of Engineers Without Borders chapter and their initial project in Bolivia, which ultimately failed. Our discussion will focus primarily on the interactions between the chapter and the primary institutions that we worked with including the University of Idaho, Engineers Without Borders USA, and Engineers in Action Bolivia. This is followed by an analysis of these interactions, the hurdles that arose within each institution, and recommendations for addressing such challenges. By examining these institutional hurdles, our goal is to provide other organizations with information useful to navigate the complex environment of community development work.
Reflection-based assessment of service learning in undergraduate engineering
Authors: Dukhan Nihad , Schumack Mark R.
Published: March 2018

Virtually all engineering education organizations from around the world agree on the critical awareness of the societal context of engineering for graduating engineers. Service learning is one viable way that can bring about students’ awareness of their role in society. However, the body of literature addressing service learning as a pedagogy and strategic ways of implementing it in the already-full engineering curricula, as well as its assessment is relatively small. This paper describes a concise engineering service-learning component in a typical heat transfer course for mechanical engineering students. The service-learning component was used to probe the students’ ability to a) articulate the societal context of engineering, b) explain the importance of pro-active community service, and demonstrate an inclination to continue such service in the future, c) exhibit an appreciation of communication with non-engineers and finally, d) challenge some of the students’ stereotypes regarding other members of the community. Reflections were conducted by the students when answering a set of carefully-phrased questions addressing the above four issues. The responses of all students were analyzed as explained in this paper. The recorded benefits of service learning are described and can be expected from similar service-learning components in other engineering courses.
EXPERIMENTAL STUDY ON BAGASSE ASH IN CONCRETE

Published: March 2018

Utilization of industrial and agricultural waste products in the industry has been the focus of research for economical, environmental, and technical reasons. Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry, along with ethanol vapor. This waste-product (Sugar-cane Bagasse ash) is already causing serious environmental pollution which calls for urgent ways of handling the waste. Bagasse ash mainly contains aluminum ion and silica. In this paper, Bagasse ash has been chemically and physically characterized, and partially replaced in the ratio of 0%, 5%, 15% and 25% by weight of cement in concrete. The Fresh concrete tests like compaction factor test, Slump cone test was obtained and hardened concrete tests like compressive strength, split tensile strength, flexural strength and Modulus of Elasticity at the age of 7 and 28 days was obtained. The result shows the increases in percentage of bagasse ash replacement, strength also increased.

Valparaiso University engineering students have completed a service learning project to design and manufacture an upgraded braille printing press for Lutheran Braille Workers, Inc., a charitable organization that provides free-of-charge, Christian print material to visually impaired individuals around the world. There are approximately 314 million blind and visually impaired individuals around the world and the need for braille print material is significant. Braille presses are used by Lutheran Braille Workers, Inc., volunteers at work centers where the braille print material is produced. Moreover, the braille press is a critical component of the production process. The project provided multiple engineering students the opportunity to design, manufacture, and implement an actual product that will benefit visually impaired individuals around the world.
Addressing Water Quality Issues in Rural Cameroon with Household Biosand Filters
Authors: Klopfenstein Laine , Petrasky Laura , Winton Valerie , Brown Jeff
Published: March 2018

This paper describes an ongoing collaboration between the Hope College student chapter of Engineers Without Borders – USA and the rural community of Nkuv in the Northwest Province of Cameroon related to improving drinking water quality using Manz Biosand filters. The collaboration began in 2006 and focused on developing a community-based construction and distribution model for household water treatment units. Results from microbiology testing of the constructed filters indicate that this water treatment method is effective for improving water quality in rural areas. The results also highlight the need for ongoing assessment and adapting community education programs to provide necessary training for filter construction and maintenance. The critical finding from this study is that transferring this technology in rural settings in developing countries may require years of iterative intervention and site specific adjustments to the construction and distribution model.
THE OCCURRENCE OF LEAD IN SOIL AND VEGETABLES AT A COMMUNITY GARDEN IN OMAHA, NEBRASKA
Authors: Sangster Jodi Lynn , Nelson Andrew , Bartelt-Hunt Shannon L.
Published: March 2018

Abstract – Lead is a persistent and ubiquitous pollutant in urban environments and is of significant importance to public health. Elevated lead concentrations in soil may be due to the use of lead-based paints, emissions from the combustion of leaded gasoline, industrial emissions, waste incineration, and pesticide application. One potential pathway for exposure to lead can be consumption of produce grown in lead-contaminated soil. This may be of increasing concern as urban community gardens experience a resurgence in popularity and demand for locally grown produce increases. For this project, soil and vegetable samples were collected from a community garden with known soil lead contamination. Soil and vegetable samples were evaluated for total lead content using atomic absorption spectroscopy. The concentrations of lead measured in soil ranged from 4 to 574 parts per million (ppm), with an average lead concentration in the growing beds of 128.4 ppm and in the OmaGro compost of 31.5 ppm.  Additionally, lead was present in vegetable samples at or below 16.25 ppm.
