Foliated field theory and string-membrane-net condensation picture of fracton order
Authors: Slagle Kevin , Aasen David , Williamson Dominic
Published: April 2019

Foliated fracton order is a qualitatively new kind of phase of
matter. It is similar to topological order, but with the fundamental
difference that a layered structure, referred to as a foliation, plays
an essential role and determines the mobility restrictions of the
topological excitations. In this work, we introduce a new kind of field
theory to describe these phases: a foliated field theory. We also
introduce a new lattice model and string-membrane-net condensation
picture of these phases, which is analogous to the string-net
condensation picture of topological order.
Determining factors to ensure the effective formation of the information process in the industrial enterprise management
Authors: Lepeyko Tetyana , Shcherbak Alina
Published: April 2019

The article presents comprehensive approach to ensuring the effective formation of the information process of industrial enterprise management. It is proposed to use scenario planning technology, which will allow considering the activity of an enterprise and its information processes in the context of several development scenarios. The paper substantiates the theoretical and methodological provisions for determining the factors ensuring the effectiveness of the formation of the information process of managing an industrial enterprise. The factors determining the effectiveness of the formation of the information process of managing an industrial enterprise are determined on the basis of the principal component method, which allows to determine the most informative indicators for further analysis and formation of the information array of the management process. It has been proved that regardless of the scenario of the development of an enterprise, the list of factors ensuring the effectiveness of the formation of information processes for managing an industrial enterprise (using the engineering industry as an example) remains unchanged, but depending on the development scenario, the priorities of the company’s management change.

Authors: Dey Sourav , Mandal Sujit ,   Department of Geography, Diamond Harbour Women’s University, South 24 Parganas, West Bengal, India.
Published: April 2019

Fluvial processes such as bank erosion plays an important role to change the channel stability of the Torsa River in the downstream region. The present study was focused on stream stability assessment of the Torsa River. The study area is situated between the downstream of the Jaldapara Reserve Forest and confluence of Kaljani River. Data of different parameters about 64 bank segments of the Torsa River were prepared using the field work techniques for assessing the stream bank conditions using lateral, vertical and overall reach stability models. The individual results of BEHI and NBS ratings show that out of 64 bank segments only 35 and 19 bank segments classified in higher categories. Overall lateral stability analysis shows that most of the sample bank segments are in an unstable condition. All bank segments are vertically unstable and degrading. Overall reach stability analysis shows widespread instability. BEHI and NBS results are almost similar for most of the bank segments and therefore, BEHI and NBS can be suitable bank erosion hazard predictive models in the study for channel stability analysis.

Different schemas of saccharification and fermentation for bioethanol production from Opuntia ficus-indica cladode flour with wild strains
Authors: López-Domínguez Cindy Mariel , Ramírez-Sucre Manuel Octavio , Rodríguez-Buenfil Ingrid Mayanín
Published: April 2019

In the present work, two wild microorganisms were studied for saccharification and fermentation. A wild Acinetobacter pittii isolated from decaying cladodes (Opuntia ficus-indica) was capable of producing extracellular cellulases and a wild yeast Kluyveromyces marxianus isolated from termite was capable of producing alcohol. In Mexico, there are surpluses of cladode production and where it is essential to take advantage and use this carbon source for alcohol production due to currently fossil fuels depletion. Separate hydrolysis and fermentation (SHF), simultaneous saccharification and fermentation (SSF) and semi-simultaneous saccharification and fermentation (SSSF) for cellulase and alcohol production using Opuntia ficus-indica cladode as a unique carbon source was evaluated. In SHF process the best conditions for FPase activity (Filter paper activity for total cellulases) were 37 °C and pH 6.5 obtaining 0.67±0.02 U/ml and 0.61±0.03 U/ml for Acinetobacter pittii and Kluyveromyces marxianus, respectively. For alcohol production, the best conditions were 40 °C and pH 5.5 obtaining 12.95±0.3 g/L with K. marxianus while A. pittii did not produce significant alcohol concentration. Both processes were made with agitation (200 rpm). The SSF process was made with both microorganisms inoculated at the same time at 37 °C and without agitation. The maximum FPase activity of 0.28±0.004 U/ml and the maximum alcohol concentration was 7.5±0.27 g/L. Finally, an SSSF was performed, initially with A. pittii at 37 °C and after 8 h K. marxianus was then inoculated with temperature switched to 40 °C, the all process was performed without agitation. The maximum FPase activity was 0.45±0.001 U/ml, and the maximum alcohol concentration was 11.7±0.02 g/L. There was a significant difference (ANOVA) between SHF and SSSF in alcohol production. The best process for FPase activity and alcohol production is separate hydrolysis and fermentation using only yeast Kluyveromyces marxianus.

Background and objectives

Our study evaluated the efficiency and safety of autologous hematopoietic stem cell transplantation treatment for patients with refractory lupus nephritis.

Design, setting, participants, & measurements

From July 2011 to January 2015, a total of 22 patients with refractory lupus nephritis were enrolled in this study. Peripheral blood stem cells were mobilized with cyclophosphamide and granulocyte colony stimulating factor and reinfused after treatment with cyclophosphamide and antithymocyte globulin. The primary end point was the rate of remission, and secondary end points included the survival and relapse rates, changes in proteinuria, kidney function, and serology immunologic test. All complications were recorded for safety assessment.

Results

Twenty-two patients were enrolled and underwent stem cell mobilization. There were nine men and 13 women, with a median lupus nephritis duration of 46 (33–71) months. The mean number of CD34+ cells was (7.3±3.8)×106/kg. All patients had successful engraftment, and the median times of granulocyte and platelet engraftment were 8 (7–9) and 9 (6–10) days, respectively. The major complications of stem cell transplantation were fever and gastrointestinal tract symptoms. The treatment-related mortality was 5% (one of 22). After a median follow-up of 72 (60–80) months, 18 (82%) patients achieved completed remission, one (5%) patient achieved partial remission, and one patient had no response and received peritoneal dialysis at 12 months after transplantation. The 5-year overall survival and disease-free survival rates were 91% and 53%, respectively. Six patients experienced relapse during the follow-up, and the relapse rate was 27%.

Conclusions

Autologous hematopoietic stem cell transplant could be used as a treatment option for refractory lupus nephritis, because it was relatively safe and associated with good outcomes.
NUMERICAL METHODS FOR THE SIMULATION OF DEFORMATIONS AND STRESSES IN TURBINE BLADE FIR-TREE CONNECTIONS
Authors: Benad Justus
Published: April 2019

In this work, different numerical methods for simulating deformations and stresses in turbine blade fir-tree connections are examined. The main focus is on the Method of Dimensionality Reduction (MDR) and the Boundary Element Method (BEM). Generally, the fir-tree connections require a computationally expensive finite element setup. Their complex geometry exceeds the limitations of the faster numerical techniques which are used with great success within the framework of the half-space approximation. Ways of extending the application range of the MDR and the BEM to the particular problem of highly undulating surfaces of the fir-tree connection are shown and discussed.
NUMERICAL IMPLEMENTATION OF FRETTING WEAR IN THE FRAMEWORK OF THE MDR
Authors: Li Qiang , Forsbach Fabian , Benad Justus
Published: April 2019

Two numerical methods are proposed to improve accuracy of the numerical calculation of fretting wear in the framework of the Method of Dimensionality Reduction (MDR). Due to the singularity of the transformation equations, instabilities appear at the border between the stick and slip regions after many transformations from the one-dimensional to the three-dimensional contact and back. In these two methods, the transformation equations are reformulated to weaken the singularity of the integrals and a stable simulation of fretting wear is realized even with the wear models which go beyond the classical Archard law. With an example of dual-oscillation, we show the change in the worn profile of a parabolic indenter as well as the stress distribution on the contacting surface during the oscillating cycles under the Archard’s law of wear and Coulomb’s law of friction.
GENERALIZED ARCHARD LAW OF WEAR BASED ON RABINOWICZ CRITERION OF WEAR PARTICLE FORMATION
Authors: Popov Valentin
Published: April 2019

According to the Archard law of adhesive wear, the wear volume is proportional to the normal force, the sliding distance, and inversely proportional to the hardness of the softer of contact partners. This law does not contain any properties characterizing “adhesion” of materials, e.g. the work of separation, either inside of the material or at the interface. The criterion for formation of wear particles, first formulated by Rabinowicz in 1958, on the contrary, is based on the interplay of elastic energy and work of adhesion and contains as governing parameters the modulus of elasticity, hardness and the work of separation. Following recent advances in understanding and simulation of wear, we discuss the ways how both laws could be melted together to a “generalized” Archard-Rabinowicz law of wear.
ENERGY LOSS AND WEAR IN SPHERICAL OBLIQUE ELASTIC IMPACTS
Authors: Willert Emanuel
Published: April 2019

Percussive and erosive wear by repetitive impacting of solid particles damages surfaces even at low impact velocities. As the impact wear is often directly related to the energy loss during the collision and therefore to the coefficients of normal and tangential restitution, in the present study the oblique low-velocity impact of a rigid sphere onto an elastic half-space is analyzed based on the known respective contact-impact solution and with regard to the energy loss during the impact. Simple analytic expressions are derived for the total impact wear volume. It is found that the portion of kinetic energy lost in frictional dissipation has a well-located maximum for configurations with weak forward pre-spin. The distribution of frictional dissipation over the contact area has a complex dependence on the impact parameters. For pronounced local slip (e.g. due to a small coefficient of friction) the dissipation accumulated over the collision is localized in the center of impact whereas for dominance of sticking, most energy is lost away from the center.
ON ADHESIVE THEORIES IN MULTILAYERED INTERFACES, WITH PARTICULAR REGARD TO "SURFACE FORCE APPARATUS" GEOMETRY
Authors: Tricarico Michele , Papangelo Antonio , Constantinescu Andrei , Ciavarella Michele
Published: April 2019

Adhesion is a key factor in many tribological processes, especially wear.  We generalize a recent formulation for the indentation of a multilayered material using an efficient integral transform method, to the case of adhesion, using a simple energetic transformation in the JKR regime. Then, we specialize the study for the geometry of the Surface Force Apparatus, which consists of two thin layers on a substrate, where the intermediate layer is softer than the other two. We find the pull-off force under "force control" (i.e. for "soft" loading systems), as well as under "displacement control" (i.e. for "rigid" systems), as a function of the geometrical thicknesses and material properties ratios, and the method is fully implemented in a fast Mathematica code, available to the public (see Appendix).
SYNERGISTIC TRIBOLOGICAL PROPERTIES OF SYNTHETIC MAGNESIUM SILICATE HYDROXIDE COMBINED WITH AMPHIPHILIC MOLECULES
Authors: Wang Bin , Chang Qiu Ying , Gao Kai
Published: April 2019

This paper reports the synthesis of magnesium silicate hydroxide (MSH) nanoparticles and their synergistic tribological properties combined with amphiphilic molecules (AMs) as additives in base oil. This combination reduces wear losses substantially due to the formation of a double well-arranged molecular layer or tribofilm on the rubbing surfaces under certain test conditions. From the results of nonequilibrium molecular dynamics (NEMD) simulations, lamellate MSH nanoparticles provide a medium for the adsorption of AMs thus further decreasing the contact of rough peaks. In addition, with the increase of load, a tribofilm containing element Mg, Si, O forms on the worn surfaces and greatly improves the anti-wear property of base oil.

Guanxi and Unethical Behavior in the Chinese Workplace: Job Satisfaction As a Mediator
Authors: Wu Ruxin , Ming Shuyuan , Huang Fei
Published: April 2019

We explored the effects of guanxi prevalence and guanxi practices on 3 types of unethical work behavior (UWB), proposing that job satisfaction would mediate the relationship between guanxi in the workplace and employees' UWB. Data were collected from 379 employees working for companies
in China. Results of hierarchical regression analysis revealed that guanxi prevalence had a positive relationship with property-related UWB and conventional and minor (ordinary) UWB, such as doing personal business in company time. Guanxi practices had a significant positive relationship with
violation of laws and regulations, property-related UWB, and ordinary UWB. Both guanxi prevalence and guanxi practices had a significantly negative relationship with job satisfaction, and job satisfaction had a significant negative correlation with violation of laws and regulations, property-related
UWB, and ordinary UWB. Job satisfaction partially mediated the relationship between guanxi prevalence and ordinary UWB. The theoretical and practical implications of these findings are discussed.
Multigroup Analysis and Measurement Equivalence: Korean And Chinese Consumers of Korean Cosmetics
Authors: Yu Jong-pil , Choi Hyun-ju , Kim Joon-ho
Published: April 2019

We examined the concepts and importance of measurement equivalence tests and how failing to conduct these tests can hinder multigroup analyses, particularly for cross-cultural or cross-national studies. To do so, we developed a conceptual model of Korean cosmetics comprising product
characteristics, consumer satisfaction, and repurchase intention, and administered a survey assessing these variables to 356 Korean and 358 Chinese consumers. We then conducted confirmatory factor analyses and multigroup analyses. The measurement equivalence test results revealed significant
differences in the measurement methods for Korean and Chinese consumers, necessitating the development of separate modified models. Specifically, the model using cosmetic product characteristics as a single factor was more suitable for Chinese than for Korean consumers. Therefore, we were
able to develop separate research models appropriate for each group. Our results also highlight the importance of assessing measurement invariance for social science researchers desiring to perform multigroup analyses in cross-national studies.

Authors: Song Jingjing , Gu Chuanhua , Zuo Bin
Published: April 2019

We aimed to determine how charitable behavior affects life satisfaction through the multiple mediating roles of self-acceptance and positive affect. We recruited 4,048 adults in China who voluntarily completed a survey on the frequency of their charitable behavior, self-acceptance,
positive affect, and life satisfaction. Results of a parallel multivariable mediation analysis showed that more frequent charitable behavior was positively associated with greater life satisfaction. Also, self-acceptance and positive affect mediated the relationship between charitable behavior
and life satisfaction. Implications for the mediating effect of charitable behavior on life satisfaction are discussed.
How Social Support Affects Moral Disengagement: the Role of Anger And Hostility

Published: April 2019

We investigated the mediating roles of anger and hostility in the relationship between social support and moral disengagement. Participants were 315 college students who completed the Perceived Social Support Scale, the Aggression Questionnaire to assess anger and hostility, and the
Moral Disengagement Questionnaire. Multiple mediation analysis results indicated that high levels of anger and hostility were associated with low levels of social support and high levels of moral disengagement. In addition, the total indirect effects and specific indirect effect of social
support on moral disengagement through anger and hostility were all significant, suggesting that anger and hostility mediated the relationship between social support and moral disengagement. Implications of these findings are discussed.
ANTHROPOLOGICAL CRISIS IN THE RISK SOCIETY: PHILOSOPHICAL ANALYSIS
Authors: Lomako O M
Published: April 2019

The article is devoted to the philosophical consideration of anthropological crisis in the risk society in his historical transformation. The research is aimed to anthropological analysis of the risk society in order to identify its new features in the modern era. As a methodological principle of research, the author defines the distinction between anthropological and cosmological approaches in philosophy. It is about their complex relationships and contradictions in the development of the civilizational process. The anthropological crisis becomes apparent when society becomes a “society of risk” in the modern era. The article reveals the cause of the anthropological crisis in the risk society: the social production of wealth becomes the production of risks. In the XXI century there is a “world society of risk” (Ulrich Beck), which is associated with the process of globalization. The risk research methodology suggests the need to anticipate unpredictable. The main difficulty in risk analysis is that the risk is between certainty and uncertainty, between rational and irrational. Two main trends - the reflexivity of the unknown and the cosmopolitan moment - point to a global change in the society in the 21st century, whose priority is security. In the historical and social philosophical perspective, security is understood as a concept that encompasses integrity, inviolability, inviolability with respect to corporeality, life and property. In the context of the modern anthropological crisis, security has become the main value concept of the social political language. The logic of uniqueness gives way to the logic of ambiguity, which finds its expression in the connection of the risk society with the cosmopolitism. The “cosmopolitan moment” of the world risk society presupposes recognition of the uniqueness of the Other as an opportunity to overcome the anthropological crisis.

Published: April 2019

One effort in controlling the Aedes aegypti mosquito is to find out the breeding place. Until now it is known that the breeding sites of Aedes aegypti are found in urban areas, therefore the purpose of this study is to determine the  potential for breeding of Aedes aegypti mosquito and entomology index in urban areas. The study was conducted in 2015 using a cross-sectional method. The results showed that the container with positively Aedes aegypti larvae was found in all three districts, Ternate at 29.6%, Tidore Kepulauan at 28.5% and East Halmahera at 29.0%. The entomology index of Container Index (CI) was (29.5%), House Index (HI) was 35.3% and Breteau Index (BI) was 69.2%, while larva free number was 64.7%. From the results of this study, it was concluded that Aedes aegypti larvae mostly found in bathtub inside the house. Tubs and plastic buckets were the type of container that were found with most positively larvae. The average ldengue vector arvae density based on CI, HI and BI (Aedes aegypti and Aedes albopictus) in the three districts / cities in North Maluku Province scale was 5-8 and included in the medium risk category. This showed that the entomology index in the North Maluku region was still low. Monitoring of the spread of mosquito breeding sites in all parts of Indonesia is still needed to reduce cases of Dengue Hemorrhagic Fever (DHF).

Use of a Hepatitis C Screening Order Set to Improve Screening Rates and Measure Intervention Effectiveness
Authors: Prince Victoria L. , McNamara Sean , Gondor Ken , Pohl Susan , Sanyer Osman , Frame Kara A.
Published: April 2019

Introduction: Hepatitis C virus (HCV) infection leads to significant morbidity and mortality. Rates of HCV infection are greatest in patients born from 1945 to 1965, so the Centers for Disease Control recommends a one-time screening in this cohort. Previous interventions utilizing the electronic medical record (EMR) capabilities at two University of Utah Family Medicine clinics have increased screening rates significantly, but further improvement is possible. 
Methods: A family medicine resident-led continuous quality improvement (CQI) team used the Model for Improvement methods popularized by the Institute for Healthcare Improvement to create a team-based intervention with the goal of improving HCV screening in a family medicine faculty and resident clinic. An order set was created and a protocol developed that allowed medical assistants or clinic phlebotomists to order the appropriate HCV screening lab if this had not yet been done by the primary care provider. Data were extracted from the EMR that showed changes in total and monthly screening rates as well as the frequency of order set use. 
Results: Monthly screening rates at the Madsen Family Medicine Clinic (Salt Lake City, UT) increased from approximately 40% to greater than 50% in the 5-month intervention period. The order set was used 19 times during this period which accounted for 18.8% of new screens.
Conclusions: Creating an order set that allows medical assistants to order the HCV screening lab increased HCV screening rates in our clinic. Because order set utilization data can be extracted from the EMR, this intervention provided a process measure that can differentiate the effect of this intervention from the effects of other interventions previously undertaken in the clinic.

Um ambiente virtual imersivo para o ensino de Sistemas Operacionais: concepção e primeiras análises
Authors: Siebra Maceu Joselice , Lima Pimentel de Sousa Verônica
Published: April 2019

A disciplina de Sistemas Operacionais (SO) tem como objetivo apresentar conceitos, mecanismos e procedimentos utilizados no desenvolvimento de sistemas operacionais. Professores e alunos enfrentam dificuldades no ensino e aprendizagem desta disciplina, pois, ela engloba definições e funcionamentos complexos e outras operações difíceis de mentalizar e descrever. Mais difícil, ainda, é representar tais conceitos concretamente. Por esta razão, algumas metodologias vêm sendo estudadas e desenvolvidas a fim de minimizar essas dificuldades. Deste modo, foi desenvolvido um ambiente imersivo 3D utilizando a plataforma OpenSim integrada ao Moodle.

Apesar de modelos de previsão de desempenho educacional ser um assunto novo, está crescendo o interesse de profissionais da área em sua utilização. Este artigo objetiva apresentar uma revisão sistemática da literatura para identificar publicações científicas sobre Sistemas de Recomendação com Learning Analytics (LA) e Mineração de Dados Educacionais (MDE) a fim de obter uma visão do estado da arte. A revisão foi realizada utilizando as bases do Portal de Periódicos da Capes o qual possui mais de 38 mil publicações, foram encontrados 251 estudos internacionais para a revisão, sendo 7 estudos incluídos para uma análise aprofundada. Entre seus principais resultados destaca-se a apresentação de indicadores gerados por LA e MDE apresentados através de Dashboards que auxiliam no processo de ensino e aprendizagem, também que não foram encontrados sistemas de recomendações para coordenadores de cursos e gestores de instituições. Em síntese, é possível que este mapeamento permita aos pesquisadores ter um panorama sobre o tema objeto de estudo e que o mesmo aponta tendências de pesquisa que poderão ser foco de futuras investigações.

Published: April 2019

A possibilidade de criação de seus próprios jogos motivam os alunos a desenvolverem o pensamento computacional e aprenderem os conteúdos curriculares envolvidos nesse processo. Entretanto, para obter um bom jogo educativo, é necessário conceber um bom Game Design. Sendo assim, a escolha de estratégias que dão suporte a elaboração do Game Design do jogo mostra-se determinante. Este artigo apresenta um relato sobre a utilização de uma proposta de concepção de Game Design de jogos digitais educativos, baseada no Design Thinking. O objetivo do trabalho é identificar como essa proposta pode estimular momentos pedagógicos significativos para a aprendizagem. Os resultados apontam que a proposta motiva os alunos a aprenderem mais sobre o processo de desenvolvimento e os assuntos abordados pelos jogos.

Authors: Rodrigues Notare Márcia , Vinicius de Azevedo Basso Marcus
Published: April 2019

Neste trabalho se discute o desenvolvimento do pensamento espacial de estudantes de matemática em processo de elaboração de programas no ambiente Logo com base na epistemologia do espaço de Jean Piaget. No estudo foram analisados programas que contemplam o uso de comandos que acionam uma terceira dimensão e possibilitam representações de resoluções gráficas de três dimensões na representação bidimensional da tela do computador. De caráter qualitativo exploratório, os resultados do estudo apontam que a atividade de programação em Logo mobilizaram estratégias envolvendo abstrações reflexionantes e pseudoempíricas, as quais ampliam as possibilidades de raciocínio espacial.

Authors: Moreira Marques Cleiton , Adelina Raupp Sganzerla Maria , Geller Marlise
Published: April 2019

Este artigo é um recorte da monografia de conclusão de curso em Ciência da Computação, descrevendo a construção de uma Tecnologia Assistiva (TA), para auxiliar no ensino da Matemática para deficientes visuais. Para que este objetivo se tornasse possível, foram realizados estudos sobre a deficiência visual, bem como as dificuldades enfrentadas na rotina de alfabetização Matemática para crianças videntes, com baixa visão e com ausência total da visão, conhecendo tal rotina, ferramentas disponíveis, e técnicas utilizadas por professores especializados em educação inclusiva. O dispositivo desenvolvido possui como inspiração principal o Material Dourado, constituindo-se uma readaptação para uma ferramenta automatizada. Assim, surgiu a “Contátil” (Contar + Tátil), capaz de representar valores numéricos, de forma tátil e audível. Sua validação foi efetivada com um grupo de 19 professores que ensinam matemática, na qual foi possível constatar o potencial da TA.

A SUBIDA DO HORTO: RITUAL E TOPOGRAFIA RELIGIOSA NAS ROMARIAS DE JUAZEIRO DO NORTE, CEARÁ, BRASIL
Authors: Da Costa Braga Antônio Mendes
Published: April 2019

Abordando um ritual denominado de “Subida do Horto” – ritual este que é realizado por devotos do Padrinho Cícero (santo popular do nordeste do Brasil) durante suas romarias à cidade de Juazeiro do Norte, Ceará, Brasil –, neste artigo, procura-se analisar a questão da topografia sagrada que é inscrita e acionada por esses devotos neste lugar de peregrinação. Igualmente busca-se analisar como esses devotos acionam e se remetem (no tempo e espaço desse ritual) a toda uma nomenclatura bíblica que nos ajuda a considerar, a pensar e a compreender como se dá a presença de uma “cultura bíblica” (Velho, 1995), “bíblica católica” (Steil, 1996), em certos contextos de devoção popular referentes ao universo religioso cristão (principalmente aqueles relativos aos contextos católicos).
