Authors: Carolina Spindola Rangel Dias Ana , Rojas Soares Felipo , Jäschke Johannes , Bezerra de Souza Maurício , Pinto José Carlos
Published: April 2019

The present work investigated the use of an echo state network for a gas lift oil well. The main contribution is the evaluation of the network performance under conditions normally faced in a real production system: noisy measurements, unmeasurable disturbances, sluggish behavior and model mismatch. The main pursued objective was to verify if this tool is suitable to compose a predictive control scheme for the analyzed operation. A simpler model was used to train the neural network and a more accurate process model was used to generate time series for validation. The system performance was investigated with distinct sample sizes for training, test and validation procedures and prediction horizons. The performance of the designed ESN was characterized in terms of slugging, setpoint changes and unmeasurable disturbances. It was observed that the size and the dynamic content of the training set tightly affected the network performance. However, for data sets with reasonable information contents, the obtained ESN performance could be regarded as very good, even when longer prediction horizons were proposed.
Touch-Typing Detection Using Eyewear: Toward Realizing a New Interaction for Typing Applications
Authors: Hasegawa Tatsuhito , Hatakenaka Tatsuya
Published: April 2019

Typing skills are important in the digital information society of this generation. As a method to improve typing speed, in this study, we focused on the training of touch typing that enables typing a key without looking at the keyboard. For support of touch-typing training, it is efficient to apply a penalty if a learner looks at the keyboard; however, to realize the penalty method, the computer needs to be able to recognize whether the learner looked at the keyboard. We, therefore, proposed a method to detect a learner’s eye gaze, namely, using eyewear to detect whether the learner looked at the keyboard, and then evaluating the detection accuracy of our proposed method. We examined the necessity for our system by analyzing the relationship between a learner’s eye gaze and touch-typing skills.
Design, Implementation and Power Analysis of Pervasive Adaptive Resourceful Smart Lighting and Alerting Devices in Developing Countries Supporting Incandescent and LED Light Bulbs
Authors: Sambandam Raju Preethi , Mahalingam Murugan , Arumugam Rajendran Revathi
Published: April 2019

Nowadays, there is an increasing demand for energy saving techniques in residential, industrial, institutional, clinical and other multipurpose indoor and outdoor applications. Lights play an ubiquitous role around the Earth in all types of structures and outdoor surroundings. Hence, the authors propose a universal lighting control device—named Pervasive Adaptive Resourceful Smart Lighting and Alerting Device—accomplished mainly by the use of Arduino UNO R3. The Pervasive Adaptive Resourceful Smart Lighting and Alerting Device works in two modes, namely, light control and alert, by deploying the perceptive light automation and perceptive light automation with buzzer activation algorithms, respectively. The contributions of the paper are: a common lighting control solution for both incandescent and light emitting diode light bulbs for all indoor and outdoor environments. A profound power consumption analysis, and investigation of the proposed device by estimating the Energy Consumption Ratio (ECR) and Relative Energy Saving Ratio (RESR) through the real time deployment in diverse circumstances with 60 W incandescent, 8 W and 0.5 W LED light bulbs is executed. In addition to the evaluation of RESR and ECR characteristics the power consumption of light bulbs in terms of scalable conditions of number of light bulbs is also analyzed. The proposed model is proved to work efficiently for both incandescent and LED light bulbs.

Published: April 2019

The aim of this study was to describe the time course (within 2 h post-exercise) of heart rate variability (HRV) recovery following a traditional repeated sprint ability (RSA) test applied to youth soccer players. Twenty-four young soccer players (18.4 ± 0.5 years) undertook the following assessments: (1) 10 min rest in the seated position for HRV assessment; (2) a repeated sprint ability (RSA) test; (3) passive recovery in the seated position for 10 min, immediately after finishing the RSA test and 1 h and 2 h post-RSA test. During the HRV measurements (using the natural log of root mean square difference of successive normal RR intervals—lnRMSSD) the participants were instructed to assume a comfortable sitting position, remaining awake and breathing spontaneously for 10 min. Magnitude-based inference was used in the analyses. After the RSA test, the post-1 h measure was almost certainly lower than the resting measure, but almost certainly higher than the lnRMSSD measured post-RSA test. The lnRMSSD post-2 h was likely lower than the resting lnRMSSD and very likely higher than post-1 h. In conclusion, lnRMSSD is severely depressed after performing an RSA test, and reactivation is incomplete after 2 h of passive recovery. This result should be considered by practitioners when applying successive training sessions within intervals shorter than 2 h.

Authors: Shrestha Ashish C. , Wijesundara Danushka K. , Masavuli Makutiro G. , Mekonnen Zelalem A. , Gowans Eric J. , Grubor-Bauk Branka
Published: April 2019

DNA vaccines present one of the most cost-effective platforms to develop global vaccines, which have been tested for nearly three decades in preclinical and clinical settings with some success in the clinic. However, one of the major challenges for the development of DNA vaccines is their poor immunogenicity in humans, which has led to refinements in DNA delivery, dosage in prime/boost regimens and the inclusion of adjuvants to enhance their immunogenicity. In this review, we focus on adjuvants that can enhance the immunogenicity of DNA encoded antigens and highlight the development of a novel cytolytic DNA platform encoding a truncated mouse perforin. The application of this innovative DNA technology has considerable potential in the development of effective vaccines.

Authors: Vindas Ramírez Karla , Araya Quesada Óscar , Román Rodrigo Cambronero , Roselló Araya Marlen , Cyrus Barker Erika
Published: April 2019

La población envejece a nivel global y considerando que la institucionalización juega un papel muy importante en esta etapa es fundamental considerar las repercusiones que ésta trae consigo en la marcha. El objetivo del estudio fue describir los principales factores  que predisponen alteraciones de la marcha (ADM) en personas adultas mayores institucionalizadas (PAMI), con edades entre 65 y 80 años.

Materiales y métodos: estudio de revisión narrativa de la evidencia existente acerca de los factores de riesgo para trastornos de la marcha (TM) en PAMI. Utilizando las bases de datos Cochrane database, MEDES,  Scielo, Trip database, Google académico y JAMDA se seleccionaron 40 artículos científicos, publicados entre el año 2013 al 2018, en idioma español e inglés.

Resultados: Según la literatura las ADM en el adulto mayor (AM) más frecuentes son, disminución de la velocidad y longitud de paso, asimetría en el movimiento y seudoclaudicación. Entre los principales factores predisponentes están: el perfil de la persona adulta mayor (PAM), caracterizado por deterioro funcional (DF), discapacidad, dependencia, comorbilidad y edad muy avanzada,  el paradigma de atención reactivo-curativo de los sistemas de institucionalización que limita el desempeño independiente del usuario, no se enfoca en la prevención y somete al individuo a reglas que obligan al sedentarismo; por último, la infraestructura suele ser deficiente e inadecuada según las necesidades de los residentes.

Conclusiones: las ADM en AM institucionalizados están influenciadas por factores intrínsecos del usuario, el modelo de atención de los centros de institucionalización y características en infraestructura.
Population trends and status of four seabird species (Uria aalge, Alca torda, Larus fuscus, Larus argentatus) at Stora Karlsö in the Baltic Sea
Authors: Olsson Olof , Hentati-Sundberg Jonas
Published: April 2019

The island of Stora Karlsö hosts the largest colonies of ﬁsh-eating seabirds in the Baltic Sea. However, recent and reliable estimates of the number of breeding pairs of the main species have been missing. Based on a complete census in 2014, we estimated the number of Common Guillemots Uria aalge to 15,700 pairs, more than half (up to 70%) of the Baltic Sea population. The number has almost tripled since the early 1970s and the increase has been particularly strong the last 11 years, with an annual increase of 5.1%. We counted 24,600 individual adult Razorbills Alca torda and estimated it to correspond to a maximum of 12,300 pairs in 2015–2016 (census over two seasons). The colony has grown strongly; on average by 5.6% annually since the early 1970s, and Stora Karlsö now hosts up to 30% of the Baltic Sea population. Stora Karlsö also hosts colonies with about 300 pairs each of Lesser Black-backed Gull Larus fuscus and Herring Gull Larus argentatus. The gulls’ trends are negative, with an average annual decline the last 10-year period by 5.0% and 6.2%, respectively.
FORMAÇÃO CONTINUADA: UMA PARCERIA PARA REFLETIR SOBRE O ENSINO DE FRAÇÃO
Authors: CANOVA RAQUEL FACTORI , Barreto Maria das Graças Bezerra , Brito Prado Maria Elisabette Brisola , Campos Tânia Maria Mendonça
Published: April 2019

Este artigo tem como objetivo de apresentar os saberes evidenciados na formação continuada de um grupo de professores que ensinam matemática para os anos iniciais sobre o conteúdo de fração e o que eles consideravam importante explorar com seus alunos. Este estudo foi desenvolvido na universidade em pareceria com a Diretoria de Ensino da rede municipal de São Paulo e envolveu a participação de 23 professores. As informações foram coletadas nos protocolos de professores, os quais representavam situações comumente trabalhadas em sala de aula e foram elaborados no início e no fim do processo formativo. Os resultados iniciais apontaram que a maior parte dos problemas elaborados pelos professores explorava apenas uma situação de fração e isso persistiu, mesmo após o processo de formação. Consideramos que esse fato pode estar relacionado à insegurança que envolve a mudança de prática e/ou o domínio do conteúdo abordado. Ressaltamos a importância de uma formação continuada reflexiva estar atenta e preocupada com a prática do professor e o seu tempo de apropriação, propiciando diferentes momentos de reflexão em grupo que permitam a reconstrução da prática e a reformulação dos conhecimentos do conteúdo a ser aprendido e ensinado.
Números racionais na forma fracionária: a influência de características formais
Authors: Freire Paulo César , Nogueira de Lima Rosana
Published: April 2019

Neste artigo, temos por objetivo analisar as características formais presentes no trabalho desses alunos com duas questões: uma envolvendo o subconstruto parte-todo, outra envolvendo o subconstruto medida, de forma a compreender como essas características influenciaram a resolução das questões. Para isso, elaboramos e aplicamos um questionário antes e depois de alunos de 6º ano do Ensino Fundamental tivessem aprendido números racionais na forma fracionária com o professor de Matemática. Os dados coletados foram analisados à luz dos Três Mundos da Matemática de David Tall, pois acreditamos que esses alunos deixaram de usar características do mundo corporificado para usarem características do mundo simbólico sem entender tal transição. Resultados mostraram que a falta de características do mundo formal pode impedir que os alunos sejam bem-sucedidos até mesmo em situações com o subconstruto parte-todo, que é mais familiar a eles.
UMA FORMA DE COMPREENDER O ENSINO DOS NÚMEROS RACIONAIS NA FORMAÇÃO INICIAL DO PROFESSOR
Authors: ELIAS HENRIQUE RIZEK , Ribeiro Alessandro Jacques , Savioli Angela Marta Pereira das Dores
Published: April 2019

Discutir os números racionais na perspectiva da formação inicial de professores de matemática é a temática que se desenvolve nesse artigo. Elaborado sob o enfoque de um ensaio teórico, os resultados aqui apresentados inserem-se em uma pesquisa mais ampla, realizada no formato de uma tese de doutorado, a qual investigou o ensino do corpo dos números racionais na formação inicial de professores de Matemática. Os referenciais teóricos que embasaram e possibilitaram a construção da proposta que é apresentada no artigo são (i) a diferenciação entre Matemática Acadêmica e Matemática Escolar, (ii) a abordagem dos Perfis Conceituais, e (iii) a noção de Conhecimento do Conteúdo no Horizonte. Dentre os resultados apresentados encontra-se a conceitualização proposta, na qual os números racionais na Matemática Escolar sejam tomados como ponto de partida e de chegada nos cursos de formação de professores, permitindo assim, que se explore situações de sala de aula que considerem diferentes contextos de significação, e que proporcione aos futuros professores uma compreensão longitudinal dos números racionais ao longo da Educação Básica. Ao mesmo tempo, intenciona-se com o modelo proposto, favorecer a ampliação da compreensão dos futuros professores para além da Matemática Escolar, promovendo assim a percepção das matemáticas como práticas sociais situadas em contextos diferentes, com objetivos e critérios de validação específicos.
Religious Zionism’s Shifting Views on Palestine and the Uganda Scheme
Authors: SONUÇ Yusuf Süha
Published: April 2019

Israeli society has social diversity. Up to the 19th century, this diversity originated from the religious views of the Jews and from the religious interpretations of the established religious groups. With the spread of secularism in the 19th century, this diversity has been divided into two main circles, religious and secular Jews. It is also possible to say that it is also present in Zionism, an ideological and social movement that emerged in the 19th century and was accepted by Jews in the same century. Zionism is briefly summarized as the wishes of the Jews to form a state in Palestine. However, the secular Zionists, who outnumber in World Zionist Organization, had not mentioned for a time in their studies, ideological books regarding Zionism, and diaries that their prospective state’s place is Palestine, Jerusalem. The pioneers of Religious Zionism, another front within Zionism, insisted on Palestine many years before the Secularists. They had always made it on religious basis although they supported the Uganda Plan for a while and behaved contrary to their wishes. In this study, reasons for insistence on the Palestinian issue of those who advocate the idea of Religious Zionism, the reasons for concessions and the lessons they have learnt from concession are discussed. Due to its content, the topic is limited from the emerging World Zionist Organization to the World War II. After the World War II and foundation of State of Israel, the supporters of Religious Zionism bandied an idea: Greater Israel. This idea is though that it should be a separate work.

Influence of traffic lights on tram’s time losses in a tram stop area
Authors: Wolek Czesław , Kowerski Sebastian
Published: April 2019

The paper presents an analysis of the impact of the location of the tram stop at intersections and near pedestrian crossings located on the sections between intersections equipped with traffic lights on the values of time lost. The research was performed in Wrocław, on the two tram stops (Pereca and Grunwaldzki Bridge) characterized by a similar location of tram stop within intersection, and on the two tram stops located on the section between the intersections with traffic lights, before (Hutmen) and behind (Bzowa) pedestrian crossing. Due to the time lost associated with waiting for the signal enabling entry to or exit from the tram, the location of the bus stop behind traffic lights is more advantageous.

Authors: Kłosek Kazimierz
Published: April 2019

The study presents basics of designing and forming earthen structures for transportation purposes on ground with poor load capacity, mainly in mining areas. Main types of retaining structures, steep slopes, and embankments reinforced by the technology will be presented. The paper also describes the mechanism of functioning these structures with additional use of geosynthetic reinforcement within the road surfaces and railway track structures, especially in the areas where continuous (subsiding troughs) and non-continuous (collapses, fissures) mining damage occurs. The basic selection criteria of soil material, reinforcement, and erosion-preventing structures will be characterized. The study contains basic principles for making check calculations of critical load capacity conditions and usability of structures for their assumed life service. Specific and executed structures will be presented, including high embankments for motorways (highways) and railway embankments, located in the areas that are subject to intense mining activity.

Published: April 2019

The strophariaceous basidiomycete Cyclocybe aegerita (synonyms Agrocybe aegerita and A. cylindracea) is one of the most praised cultivated edible mushrooms and is being cultivated at large scale for food production. Furthermore, the fungus serves as a model organism to study fruiting body formation and the production of secondary metabolites during the life cycle of Basidiomycota. By studying the secondary metabolite profiles of C. aegerita, we found several terpenoids in submerged cultures. Aside from the main metabolite, bovistol (1), two new bovistol derivatives B and C (2, 3) and pasteurestin C as a new protoilludane (4) were isolated by preparative HPLC. Their structures were elucidated by mass spectrometry and NMR spectroscopy. The relative configurations of 2–4 were assigned by ROESY correlations, and 3JH,H coupling constants in the case of 4. Applying quantitative PCR for gene expression validation, we linked the production of bovistol and its derivatives to the respective biosynthesis gene clusters.
Electron Acceleration in Middle-age Shell-type γ-Ray Supernova Remnants
Authors: Zhang Xiao , Liu Siming
Published: April 2019

Over the past decade, γ-ray observations of supernova remnants (SNRs) and accurate cosmic-ray (CR) spectral measurements have significantly advanced our understanding of particle acceleration in SNRs. In combination with multiwavelength observations of a large sample of SNRs, it has been proposed that the highest energy particles are mostly accelerated in young remnants, and the maximum energy that middle-age and old SNRs can accelerate particles to decreases rapidly with the decrease in shock speed. If SNRs dominate the CR flux observed at Earth, a large number of particles need to be accelerated in old SNRs for the soft CR spectrum even though they cannot produce very high-energy CRs. With radio, X-ray, and γ-ray observations of seven middle-age shell-type SNRs, we derive the distribution of high-energy electrons trapped in these remnants via a simple one-zone leptonic emission model and find that their spectral evolution is consistent with such a scenario. In particular, we find that particle acceleration by shocks in middle-age SNRs with age t can be described by a unified model with the maximum energy decreasing as t
−3.1 and the number of GeV electrons increasing as t
2.5 in the absence of escape from SNRs.

O CONCEITO DE ESPAÇO DE REPRESENTAÇÃO DO FUTEBOL COMO POSSIBILIDADE PARA APREENSÃO DO FUTEBOL PROFISSIONAL E AMADOR COMO FENÔMENOS DA ESPACIALIDADE
Authors: Gallego Campos Fernando Rosseto
Published: April 2019

Reconhecendo a importância do futebol como elemento esportivo, social, econômico, cultural e também espacial, este artigo tem como objetivo apresentar o conceito de espaço de representação do futebol como forma de apreensão tanto do futebol profissional quando do futebol amador como fenômenos da espacialidade. Baseado no conceito de espaço de representação (espaço vivido) de Lefebvre (1991), o espaço de representação do futebol é a instância da espacialidade em que as experiências futebolísticas são plenamente vividas. Ele é formado pela interação de diversos elementos organizados em categorias centrais (fato futebolístico, prática social do futebol e relações), reinos (organização, ethos futebolístico e emoções) e categorias de mediação (estruturações identitárias futebolísticas, mitos, símbolos e discurso). Estes elementos apresentam uma diversidade de apropriações no futebol profissional e no amador. Estas apropriações, que se manifestam através de territorialidades diversas, geram infinitas combinações, já que são inúmeras as significações e formas pelas quais o futebol se apresenta. Entretanto, identificamos em um extremo o espaço de representação ideal do futebol profissional (pautado em competição, rendimento, resultado, poder, remuneração e estrutura institucional estabelecida) e em outro o espaço de representação ideal do futebol amador (baseado no lúdico e em relações que não passam por instituições, contratos ou remunerações). Entre estes espaços de representação ideais do futebol se enquadram todas as formas de futebol, através de diversos espaços de representação do futebol.

Published: April 2019

O caos do Sistema Único de Saúde (SUS) expõe as dificuldades daqueles que necessitam de atendimento. Assim, pessoas sofrendo em macas ou muitas vezes no chão dos hospitais, tornaram-se paisagens cotidianas. Essa dura realidade tem atemorizado os usuários que procuram respostas para esses impasses. O presente trabalho tem como objetivo apresentar alguns fatores que interferem na oferta de serviço de qualidade na rede pública de saúde no município de Jataí (GO). Para esta pesquisa, foram adotados os seguintes procedimentos metodológicos: revisão bibliográfica acerca dos conceitos de redes de saúde; investigação junto a órgãos como a Secretaria Municipal de Saúde (SMS), Prefeitura Municipal de Jataí, Instituto Brasileiro de Geografia e Estatística (IBGE), entre outros. Foi utilizado os Softwares ArcGis para confecção dos mapas e Excel para organização de gráficos. O trabalho revelou que a rede pública de saúde do município demonstra uma preocupante centralização de serviços no único hospital da cidade que realiza atendimento de urgência/emergência via SUS. Além disso, o crescimento demográfico e das causas externas como a violência, o trânsito e o tráfico de drogas, sobrecarregam as Unidades Básicas (UBSs) da rede de saúde, que assim como o hospital não conseguem atender toda a demanda.

Published: April 2019

Conhecer as características físicas das bacias hidrográficas é um processo fundamental para o planejamento de uso e ocupação das terras. O presente trabalho objetivou delimitar e caracterizar as sub-bacias formadoras da Pequena Central Hidrelétrica (PCH) Mosquitão. Para o desenvolvimento do trabalho, foram utilizados dados pedológico, geológico, litológico, geomorfológico, hipsométrico, de declividade, drenagem e de uso e ocupação das terras. A metodologia utilizada foi por meio do Sistema de Informações Geográficas (SIG), com a ferramenta de apoio programa ArcGis 10.1, sendo as bases cartográficas adquiridas pela Instituto Brasileiro de Geografia e Estatística (IBGE), Sistema Estadual de Geoinformação (SIEG), Companhia de Pesquisa de Recursos Minerais (CPRM) e pela Empresa Brasileira de Pesquisa Agropecuária – EMBRAPA. Como resultado, têm-se como classes predominantes: pedologia – argissolos e latossolos; geologia – ortognaisses do Oeste de Goiás e formação ponta grossa; litologia – rochas areníticas e graníticas; geomorfologia – superfície regional de aplainamento; hipsometria – de 500 a 700m; declividade – 0 a 20%; drenagem – 6ª ordem; uso e ocupação das terras houve um considerado aumento de agricultura e diminuição da pastagem na bacia em questão. As classes analisadas dão-se de forma heterogênea, as quais devem ser observadas com atenção, pois a intensificação das ações antrópicas sobre a bacia pode oferecer degradação ambiental.
CIDADES PEQUENAS NA FRONTEIRA: OS CASOS DE CARACOL E BELA VISTA, NO MATO GROSSO DO SUL, BRASIL
Authors: Moreira Junior Orlando
Published: April 2019

Este artigo apresenta algumas considerações sobre a configuração intra-urbana associada à dinâmica sócio-demográfica, econômica e de organização do espaço de cidades pequenas localizadas em uma região fronteiriça, tendo como referencial empírico as cidades de Caracol e Bela Vista, no estado de Mato Grosso do Sul, Brasil. Ambas fazem fronteira com o Paraguai. A cidade de Caracol é analisada a partir do isolamento territorial, cujo núcleo urbano localiza-se distante de outras cidades, caracterizado pelo entorno rural e pelas ruralidades. Em contrapartida, Bela Vista possui uma dinâmica urbana diferenciada, marcada pela conurbação internacional com a cidade de Bella Vista Norte no Paraguai. O fato de se tratar de uma cidade gêmea traz consigo algumas problemáticas que envolvem questões de segurança e ilegalidade, bem como atuação do Estado para defender a soberania nacional. Deste modo, pretende-se apresentar um estudo sobre cidades pequenas ante o cenário regional fronteiriço, visto que a dinâmica espacial, demográfica e as relações socioeconômicas possuem interações diferenciadas que ajudam a compreender os papéis e significados urbanos por elas assumidos, bem como as especificidades da dinâmica interna de seus espaços.
Microwave Facilities for Thermal Treatment of Honey
Authors: Dimiņš Fredijs , Miķelsone Velga , Augšpole Ingrīda , Niklāvs Artūrs
Published: April 2019

Often we are faced with the need for thermal treatment of honey. Traditionally this is done by heating the honey. This process requires certain time consumption. Thermal treatment can be greatly accelerated by the use of microwaves. Indicators for thermal treatment and storage of honey traditionally are hydroxymethylfurfural (HMF) content and activity of enzymes. HMF is organic compound, which is created when carbohydrates are dehydrated. HMF content increases when honey is stored for long time or is thermally treated. Our objective of the study was to find out how the different types of honey heat treatment affect the honey enzyme, invertase, activity and HMF content. HMF content in honey was determined using high pressure liquid chromatography. Invertase activity is determined by spectrophotometry. The study results proved that using microwaves to thermally treat honey significantly impacts honey invertase activity and HMF content increases. Invertase activity reduction is more severe compared to the HMF content increase. Thermally treating honey with microwaves, even treating it only 10 seconds, affects the quality of honey.

Developed by ADC, involving clay minerals available in Latvia as well as wood fibers; 2 appropriate composites are selected. The coating's effectiveness has been estimated for odour in the environment, and the coating has been tested in field conditions. The obtained coating shows the ability to maintain a physical condition more than a month without changing its consistency. Compared with commercially available daily cover, which is many times higher in price, the developed coating exhibits the same odour characteristics. It is recommended to continue testing and assess the ability to absorb harmful elements by using this coating.

The objective of this study was the synthesis of various activated carbons from grape marc issued from oenological by-product as a biosorbent. The biosolid was then applied to remove an industrial dye (red bemacid ETL) in aqueous solution. Activation of the synthesized charcoal was carried out using a solution of zinc chloride induced by two physical methods (microwaves and heating at 300°C). The obtained materials are characterized by FTIR and SEM methods. Results from batch adsorption tests have shown that pH solution, initial dye concentration and contact time affect the adsorption mechanism. Removal of the industrial dye revealed second order kinetics, exothermic adsorption and isothermal adsorption of BET type.

Hydroxyapatite (HAp) has shown the ability to store a charge induced by electrical polarization a method potential for improved bone ingrowth. In this work electrical polarization was carried out on HAp ceramics with three different microstructures, obtained at three different sintering temperatures. Microstructure of the sintered HAp was evaluated from density measurements and SEM observations. Sintered HAp tablets were electrically polarized in an electric field of 5 kV/cm at 400 °C for 1h. Surface charges investigated by thermally stimulated depolarization current measurements showed 104,8 μC/cm2 for denser tablets, while charge density of 22,8 μC/cm2 was obtained for less dense tablets.

A series of glassy 6-(tert-butyl)-4H-pyran-4-ylidene malononitrile (DCM) derivatives with covalently attached amorphous state promoting bulky 1,1,1-triphenylmethyl (trityl) moieties through several chemical design approaches have been synthesized and investigated for suitability in organic solid state laser applications. Results showed that the bonding type of such functional groups had a considerable influence on glass structure forming dye thermal properties and a slight influence on their optical properties. Thermal stability up to 346 °C was achieved with glass transitions in the range from 39 to 138 °C. Incorporation of bulky triphenyl substituents via ester groups showed remarkable amplified spontaneous emission (ASE) threshold energy value reduction by 1.7 times in comparison to other bonding approaches with excitation threshold energy density up to 91 µJ/cm2. Synthesized dyes show potential as the light-amplification medium component in organic solid state lasers.
Characterization of the Pore Structure in Ice from Water Added at Different Temperatures
Authors: Shishkin Andrejs , Stafecka Ieva
Published: April 2019

The present study describes ice characterization technique by utilizing light microscopy. Two different optical setups were used and compared. For ice structure characterization, ice was formed by adding water to an ice base layer: pouring hot water (+20 °C), pouring cold water (+3 °C) and spraying of hot water (+20 °C) water. Ice substrate specimens were made (20 x 30 x 20 mm prepared in a polypropylene mould) at -20 °C for 48 h. The heat flow direction governed the orientation of the air bubbles, and set the inner structure of ice. Pouring hot water onto ice slowly solidified the top layer and created channel-like pores perpendicular to the top surface, but cold water quickly solidified the top layer and created chaotically oriented air bubbles.
Effect of Surface Modification on the Wettability and Static Coefficient-of-Friction between Steel and Ice
Authors: Stafecka Ieva , Pluduma Liene , Lungevics Janis , Gross Karlis Agris
Published: April 2019

The effect of surface topography in combination with chemical composition on hydrophobicity and static coefficient-of-friction between steel and ice was studied. Polished stainless steel blocks were etched to introduce a roughness, and further treated with octadecanethiol. Carbon rich inclusions, identified by energy-dispersive X-ray spectroscopy, and scratches acted as the exposure centers to promote etching. Due to heterogeneities in steel, rounded cavities and parallel troughs were found on the surface after etching. Etched blocks with a lowered surface energy were studied under various ambient conditions to determine the influence of ice temperature and humidity on the static coefficient-of-friction. Blocks modified with octadecanethiol showed improved hydrophobicity. Warmer ice conditions led to a lower friction, regardless of the surface modification.
Skeleton Runner Roughness and Surface Contact Area Influence on Sliding Ability: Field Experiments
Authors: Lungevics Janis , Jansons Ernests , Gross Karlis Agris
Published: April 2019

Scientists and sport athletes are constantly seeking for the methods which could improve surface sliding ability on ice. Modifications of contact area and surface roughness are relatively easy but not yet fully understood methods for sliding ability improvements. This research contains information of how one can perform on-field experiments with skeleton sleigh to determine the influence of surface contact area and roughness on sliding ability. Two types of surface roughness i.e. polished (3000 grain sandpaper) and scratched (600 grain sandpaper) are compared using three different contact areas. Obtained data showed that rougher surfaces tend to slide faster if contact area is larger but the effect reverses if contact area is reduced.
The Impact of Ice Texture on Coefficient of Friction for Stainless Steel with Different Surface Roughness
Authors: Jansons Ernests , Gross Karlis Agris
Published: April 2019

Winter forces people to adapt to snow and ice conditions and understand the regularities in nature in the cold regions. The understanding of ice and snow regularities can help to improve the safety of moving over ice. The objective of this work was to investigate the impact of ice texture on the static coefficient of friction for stainless steel samples with different surface roughness under laboratory conditions. The ice was prepared flatted, scratched and glazed to represent the various ice textures which might appear in real-life situations. The samples were prepared as rectangular stainless steel blocks with different surface roughness. Contact area between the sample and the ice was considered as the most influential factor. A larger contact area resulted in a higher static coefficient of friction. This outcome provides useful information for working in surroundings with ice.

Oxazolidinones are an important class of heterocyclic compounds that are used as chiral auxiliaries in asymmetric synthesis and as biologically active pharmaceutical agents. Moreover, carbohydrates are ideal scaffolds to generate libraries of bioactive compounds due the presence of defined configuration. We report here asymmetric alkylation studies on N-derivatized glucose-and allose-based spirooxazolidinones which do act as chiral auxiliaries.

Expanding Self-Management Support From Chronic to Acute Care: Implications for Value
Authors: Stern Brocha Z.
Published: April 2019

In this article, I advocate the expansion of self-management support from chronic to acute care as a means of increasing the value of services and highlighting the value of occupational therapy. Like people with chronic conditions, clients with acute conditions (1) need to participate in their own care, (2) require support for participation, (3) engage in care outside of traditional medical behaviors, and (4) benefit from a focus of care that extends beyond discrete episodes. Self-management support can facilitate adherence, promote holistic conceptualizations of health, and address long-term outcomes and costs. Given that self-management support aligns with occupational therapy’s philosophical roots, expansion of self-management support to acute care highlights the profession’s contribution to health promotion in this practice area.
