Comparison of emissions depending on the type of vehicle engine
Authors: Rievaj Vladimír , Gaňa Ján , Synák František 
Published: July 2019

Abstract
Road transport is showing growth in the period of globalization. Its task is to transport cargo as well as people to the required location within the shortest possible time and at the lowest price. Thus, road transport plays a crucial role in enabling the globalization to be developed and improved. However, the internal combustion engine hat prevail among the vehicles of freight and passenger transport are the producers of gaseous emissions from the exhaust gases. Many developed countries of the world has committed themselves, inter alia also trough the Paris Agreement, to reduce global warming, and thus to reduce the production of harmful gaseous emissions. The result is the endeavour to replace the internal combustion engine vehicles that burn carbon fuels with the vehicles powered by electric motors consuming electric energy. The reason of such trying claims that road transport using the internal combustion engine vehicles is environmentally aggressive, and the problem would not be solved by implementation of the vehicles with electric motors. Such claim is based on the fact that an electric car does not produce any of primary emissions. From an overall perspective, it is also necessary to take into account secondary emissions that are produced during the electric energy production by which is the vehicle with electric motor powered. The purpose of this article is to assume the possibility of reducing global pollution by replacing the internal combustion engine vehicles with the vehicles powered by electric motors in dependence with producing the emissions during the production of electric energy.
Walking Through, Going Along and Scrolling Back: Ephemeral mobilities in digital ethnography
Authors: Møller Kristian , Robards Brady 
Published: July 2019

Abstract
Spatial metaphors have long been part of the way we make sense of media. From early conceptualizations of the internet, we have come to understand digital media as spaces that support, deny or are subject to different mobilities. With the availability of GPS data, somatic bodily movement has enjoyed significant attention in media geography, but recently innovations in digital ethnographic methods have paid attention to other, more ephemeral ways of moving and being with social media. In this article, we consider three case studies in qualitative, “small data” social media research methods: the walkthrough, the go-along and the scroll back methods. Each is centred on observing navigational flows through app infrastructures, fingers hovering across device surfaces and scrolling-and-remembering practices in social media archives. We advocate an ethnography of ephemeral media mobilities and suggest that small data approaches should analytically integrate four dimensions of mediated mobility: bodies and affect, media objects and environments, memory and narrative, and the overall research encounter.
A Room of One’s Own?: Using period trackers to escape menstrual stigma
Authors: Karlsson Amanda 
Published: July 2019

Abstract
This article’s ambition is to study the needs and motives embedded in the everyday usage of period trackers.
A period tracker is an app for smartphones to monitor the female cycle.
Based on twelve in-depth interviews with Danish women who use period trackers, I explore the connections among menstrual stigma and the usage of period trackers and investigate how digital traces from their datafied
By datafied body, I mean the representation of the fleshly, physical body created by tracked data.
bodies transmit meaning to their everyday life. The women in the study described how the app provides them with reassurance and privacy, and thus the article finds that 1) period apps are experienced as private, shame-free rooms for exploratory engagement with the menstruating body and 2) the risk of embodied data potentially becoming shareable commodities does not affect the everyday self-tracking practice of these women.
Encounters with Self-Monitoring Data on ICT Use
Authors: Saariketo Minna 
Published: July 2019

Abstract
This article elaborates on the prospects for research interventions that repurpose the means of datafication to create possibilities for people to reflect on what it means in their daily lives. The research data consist of qualitative research interviews (n=13) in which media diaries and tracking data from the participants’ smartphones and computers served as prompts for reflection. The experiences from the self-monitoring and the encounters with tracked data by self-identified avid ICT users are analysed to gain a better understanding of the kinds of possibilities for reflexivity that are enabled when people have access to data that are rarely available to them.
Four Styles of Quali-Quantitative Analysis: Making sense of the new Nordic food movement on the web
Authors: Munk Anders Kristian 
Published: July 2019

Abstract
Through the example of a web corpus built to study the emergence of the New Nordic Food phenomenon in Scandinavia, I discuss how quali-quantitative analysis can help us make sense of onlife traces. I propose four styles of analysis that address the meaning problem in different ways, namely 1) through complementarity, a division of labour in which quantitative and qualitative methods are allowed to unfold relatively undisturbed by one another, the latter performing the job of situating and interpreting the insights gleaned from the former; 2) through a single level of analysis, whereby the potential of onlife traces is seen to reside in their ability to be both qualitatively rich and quantifiable at the same time, enabling an analysis of how apparent macro phenomena are produced on the micro level; 3) through curation, a critical practice in which a qualitative understanding of different media environments and their effects on the production of onlife traces becomes integral to the way in which such data should be sourced and quantified; and 4) through algorithmic sensemaking, whereby the relational reasoning typically associated with qualitative fieldwork is emulated quantitatively through techniques like pattern recognition.
Dry and steam reforming of methane. Comparison and analysis of recently investigated catalytic materials. A short review.
Authors: Summa Paulina , Samojeden Bogdan , Motak Monika 
Published: July 2019

Abstract
In order to produce valuable syngas, industrial processes of dry reforming of methane and steam reforming of methane must be further developed. This paper is focused on reviewing recently examined catalysts, supporting the mentioned technologies. In both processes the most popular active material choice is usually nickel, due to its good availability. On the other hand, noble metals, such as ruthenium, rhodium or platinum, provide better performance, however the solution is not cost-effective. Materials used as a support influence the catalytic activity. Oxides with basic properties, such as MgO, Al2O3, CeO2, are frequently used as carriers. One of the most promising materials for reforming of methane technologies are hydrotalcites, due to adjustable composition, acid-base properties and possibility of incorporation of various metals and complexes.
Immobilization of permeabilized cells of baker’s yeast for decomposition of H2O2 by catalase
Authors: Trawczyńska Ilona 
Published: July 2019

Abstract
Permeabilization is one of the effective tools, used to increase the accessibility of intracellular enzymes. Immobilization is one of the best approaches to reuse the enzyme. Present investigation use both techniques to obtain a biocatalyst with high catalase activity. At the beginning the isopropyl alcohol was used to permeabilize cells of baker’s yeast in order to maximize the catalase activity within the treated cells. Afterwards the permeabilized cells were immobilized in calcium alginate beads and this biocatalyst was used for the degradation of hydrogen peroxide to oxygen and water. The optimal sodium alginate concentration and cell mass concentration for immobilization process were determined. The temperature and pH for maximum decomposition of hydrogen peroxide were assigned and are 20°C and 7 respectively. Prepared biocatalyst allowed 3.35-times faster decomposition as compared to alginate beads with non permeabilized cells. The immobilized biocatalyst lost ca. 30% activity after ten cycles of repeated use in batch operations. Each cycles duration was 10 minutes. Permeabilization and subsequent immobilization of the yeast cells allowed them to be transformed into biocatalysts with an enhanced catalase activity, which can be successfully used to decompose hydrogen peroxide.
The construction of cooperative and inferential meaning by children with Asperger syndrome
Authors: Rodríguez Muñoz Francisco J. 
Published: July 2019

Abstract
This study aims to apply the Gricean theory of conversational cooperation to the example of inferential meaning in the oral speech of children with pragmatic deficit. Firstly, the analysis pays attention to the use of tropic inferences and particularized implicatures in conversation. Secondly, it focuses on the degree of maintenance or flouting with regard to conversational maxims. On average, study participants are 11.15 years old and possess a confirmed clinical diagnosis of Asperger syndrome. Results suggest a rare understanding and production of tropic inferences and particularized implicatures in dialogues, as well as the systematic application of the maxim of quality, the generalized non-fulfilment of the maxim of quantity and different degrees of fulfilment according to the remaining maxims.
The new big picture for linguistics: Complex systems
Authors: Kretzschmar William A. 
Published: July 2019

AbstractIn the history of linguistics there have been crucial moments when those of us interested in language have essentially changed the way we study our subject. We stand now at such a moment. In this presentation I will review the history of linguistics in order to highlight some past important changes in the field, and then turn to where we stand now. Some things that we thought we knew have turned out not to be true, like the systematic, logical nature of languages. Other things that we had not suspected, like a universal underlying emergent pattern for all the features of a language, are now evident. This emergent pattern is fractal, that is, we can observe the same distributional pattern in frequency profiles for linguistic variants at every level of scale in our analysis. We also have hints that time, as the persistence of a preference for particular variants of features, is a much more important part of our language than we had previously believed. We need to explore the new realities of language as we now understand them, chief among them the idea that patterned variation, not logical system, is the central factor in human speech. In order to account for what we now understand, we need to get used to new methods of study and presentation, and place new emphasis on different communities and groups of speakers. Because the underlying pattern of language is fractal, we need to examine the habits of every group of speakers at every location for themselves, as opposed to our previous emphasis on overall grammars. We need to make our studies much more local, as opposed to global. We do still want to make grammars and to understand language in global terms, but such generalizations need to follow from what we can now see as the pattern of language as it is actually used.

Published: July 2019

Observa-se atualmente um cenário onde há um progressivo envelhecimento populacional, associado a um predomínio de doenças crônico-degenerativas de evolução lenta. Dentro deste contexto, os Cuidados Paliativos se inserem como uma medida extremamente necessária, de promover qualidade de vida, prevenir e aliviar o sofrimento de indivíduos e de seus familiares. Com base nesta problemática, surge o interesse em avaliar a partir de um questionário, como os estudantes que irão se formar em medicina se sentem a respeito do conhecimento e tratamento da dor, e como se comunicam com seus pacientes. Registros da literatura apontam que o médico tem sua formação acadêmica toda voltada para o diagnóstico e tratamento de doenças, assim, quando defronte de um paciente necessitado de Cuidados Paliativos, o foco deixa de ser a doença e passa a ser a pessoa doente. De forma a garantir não só alívio de sintomas desconfortáveis, mas também a dignidade de vida até o fim. Trata-se de um estudo longitudinal, prospectivo, de caráter quantitativo, realizado na Universidade Ceuma, em São Luís- MA, com estudantes de medicina do primeiro ao décimo segundo período, aprovado pelo Comitê de Ética e registrado sob o número de parecer 2.101.716. Foram avaliados 232 acadêmicos a partir de um questionário com perguntas fechadas, analisadas de acordo com os seguintes aspectos: formação técnica, percepção dos conhecimentos fisiopatológicos, semiologia e terapêutica associadas a dor e cuidados paliativos. A idade dos participantes variou entre 17 e 32 anos com prevalência de 52,6% com a faixa etária de 21|---|24 anos, e quanto ao gênero, a ocorrência de 69,0% do sexo feminino. A maioria dos alunos não conhece a definição de Cuidados Paliativos da Organização Mundial de Saúde (61%), e não se sente à vontade para comunicar más notícias aos pacientes e familiares. Assim, acredita-se que a criação de uma disciplina específica para Cuidados Paliativos, poderia sanar as deficiências educacionais aqui levantadas nos graduandos e eventuais egressos.

Published: July 2019

A Leishmaniose Tegumentar Americana (LTA) é uma doença causada por protozoários do gênero Leishmania, transmitida ao homem pela picada de mosquitos flebotomíneos. As formas clínicas da leishmaniose tegumentar americana são as mais variadas. Na leishmaniose cutânea (LC), na sua fase aguda, geralmente o quadro se inicia com pápula nos locais da picada do inseto que, basicamente, acometem áreas descobertas do corpo. Na leishmaniose mucosa (LM), a lesão atinge de preferência as vias aéreas superiores. O Brasil é considerado o terceiro país com o maior número de casos novos em todo o mundo, com uma média de 21.000 casos anuais. Trata-se de uma doença endêmica no Brasil, tendo distribuição em todo território nacional, com maior casuística na Pré-Amazônia Maranhense. O estado do Maranhão é o segundo em número absoluto de casos de LTA dentre todos os estados do país. OBJETIVOS: O objetivo principal desse estudo é apresentar o perfil epidemiológico dos casos de Leishmaniose Tegumentar Americana no Estado do Maranhão, no período de 2015 a 2017, a partir de dados coletados no SINAN de forma a contribuir para a melhoria das informações disponibilizadas da doença no estado. METODOLOGIA: Este trabalho consiste em uma pesquisa observacional, descritiva, quantitativa com base nos dados notificados e cadastrados no Sistema de Informações de Agravos de Notificações. Os mesmos serão transcritos para o programa Microsoft Excel e tabulados para posterior realização da análise estatística descritiva através do cálculo das frequências relativas das respostas dadas, sendo os resultados apresentados em porcentagens na forma de gráficos e tabelas.Palavras chaves: Leishmania.

Os medicamentos provenientes de plantas estão presentes há milhares de anos na população. Muitas pessoas fazem uso destes produtos na forma de comprimidos, cápsulas, xaropes ou ainda utilizando a planta seca, inteira ou fracionada principalmente na forma de chás. A espécie Byrsonima crassifolia tem um grande potencial de ação terapêutico e está amplamente distribuída na Amazônia Brasileira, América Central e Caribe, sendo conhecida popularmente no Brasil com o nome de muricizeiro. Diversos registros na literatura abordam suas propriedades farmacêuticas, seja para o tratamento do controle da diabetes, depressão e de quadros inflamatórios. Por observar esta vasta quantidade de usos na literatura e, diante da necessidade de um cuidado maior na utilização de medicamentos provenientes de plantas em virtude de agentes tóxicos, foi realizado um estudo de revisão de literatura sobre as propriedades farmacêuticas e o potencial citotóxico de B. crassifolia. Palavras-chave: Byrsonima crassifolia. Muricizeiro. Propriedades farmacêuticas. Potencial citotóxico.
Ciência médica para cura dos males humanos
Authors: Monteiro Sílvio Gomes 
Published: July 2019

Na antiguidade a medicina era exercida inicialmente pelos sacerdotes, mas foi com o “pai da Medicina”, Hipócrates, que ela passou a ser transformada numa “ciência”, quando ele passou a adotar métodos específicos para a pesquisa dos males humanos. É lógico que a base da pesquisa científica só surgiu cerca de 2000 anos depois com René Descartes ao escrever o Discurso do Método (1637), segundo o qual dizia que só se pode chegar à verdade através da dúvida sistemática e da decomposição do problema em pequenas partes. Assim, podemos dizer que o mais importante é a incessante busca do saber, pois como se diz “Há verdadeiramente duas coisas diferentes: saber e crer que se sabe. A ciência consiste em saber; em crer que se sabe reside a ignorância”. Por isso que é admirável a atual formação dos novos médicos, da aprendizagem baseada em problemas que existem nas diversas Faculdades de Medicina do mundo, pois assim temos não só médicos que saibam curar os males humanos, mas também que saibam pensar criticamente e cientificamente possibilitando assim fazer novas descobertas. Desse modo, este novo volume da Revista de Investigação Biomédica 10 artigos científicos de alunos do curso de medicina em suas pesquisas de conclusão de curso. Sendo 2 artigos originais, o primeiro investiga o grau de conhecimento dos estudantes de medicina sobre cuidados paliativos e dor, e o segundo estima a prevalência das hepatites B e C em moradores de rua em São Luís-MA.Os outros artigos são artigos de revisão da literatura, os quais discutiram o uso da testosterona no envelhecimento masculino; a epidemiologia e estratégias de prevenção do câncer de pênis no estado do Maranhão; Câncer de mama em homens; o perfil epidemiológico dos casos de Leishmaniose Tegumentar Americana no Maranhão; o uso de imunoglobulinas na terapêutica da púrpura trombocitopênica imune; a acurácia da ultrassonografia com preparo intestinal no diagnóstico da endometriose profunda; a ultrassonografia das mãos no diagnóstico precoce e seguimento clínico de pacientes com artrite reumatoide e as propriedades farmacológicas de Byrsonima crassifolia. Desta forma, cada um desses artigos representa o início do cumprimento do juramento de Hipócrates para cada um desses novos profissionais e cientistas da saúde, ou seja, o consagramento da sua vida à serviço da Humanidade.

Guided-mode Resonance Filter with Ultra-narrow Bandwidth over the Visible Frequencies for Label-free Optical Biosensor
Authors: Dang Phuc Toan , Q. Le Khai , Ngo Quang Minh , Nguyen Hieu Pham Trung , Nguyen Truong Khang 
Published: July 2019

A practical guided-mode resonance filter operating in the visible band of the electromagnetic spectrum is numerically designed in this paper. The filter provides high background transmission (>90%) with almost perfect reflection at resonance wavelengths of 623 nm and 641 nm for TE and TM modes, respectively. Our filter is also characterized by its sensitivity to incident angles, polarizations, and a refractive index of the surrounding environment which are utilized in practical applications such as tunable optical filters, imaging or detection. We show that the resonant transmission spectral response can be used for highly sensitive, a potential label-free refractive index biosensor having sensitivities of 90 nm/RIU and 103 nm/RIU, and figure of merits of 1.93 and 2.13 for TM and TE polarizations, respectively.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
