Evidence for Holocene Activity on the Jiali Fault, an Active Block Boundary in the Southeastern Tibetan Plateau
Authors: Wang Hu , Li Kaijin , Chen Lichun , Chen Xingqiang , Li An
Published: April 2020

Most active block boundary faults within the Tibetan plateau have been thought of as Holocene active, and are able to produce large earthquakes. However, it is unknown whether the Jiali fault (JLF) has been seismically active in the Holocene, which currently hampers efforts to undertake meaningful seismic hazard assessments near the southeastern part of the Tibetan plateau. In this study, it is shown that the JLF has indeed ruptured during the Holocene, as evidenced from geological, paleoseismic, and radiocarbon dating investigations. Specifically, at least two surface-rupturing paleoseismic events were revealed with ages between 2160±30  yr B.P. and 2680±30  yr B.P., and prior to 2730±30  yr B.P., respectively. Combined with previous studies on the JLF, we suggest that the fault (1) can be considered an active block boundary fault and (2) accommodates crustal deformation related to the uplift of the Tibetan plateau since the late Cenozoic.
A negatividade da poética de João Cabral
Authors: Paula Felipe Oliveira de
Published: April 2020

No primeiro momento, situo a discussão entre os críticos cabralinos sobre a noção de negatividade. Alio a esse breve apontamento de parte da fortuna crítica do poeta o conceito de negatividade desenvolvido por Theodor Adorno ao longo de seus trabalhos, concentrado em Dialética Negativa. Em seguida, procuro demonstrar qual como se estabelece uma chave interpretativa para analisar a poesia de Cabral. A negatividade, tal como trabalhada, se apresenta como ferramenta promissora para investigar como o questionamento da linguagem na poética cabralina reflete os elementos técnicos literários e, a um só tempo, configura uma poética crítica a dispositivos sociais, sobretudo quando esses não aparecem explicitamente.

O pós-colonial como ponto de vista, uma nota sobre Silviano Santiago
Authors: Miggiolaro Chaguri Mariana , Marmerolli Tresoldi Maria Caroline
Published: April 2020

Este artigo argumenta sobre a novidade teórico-metodológica de Uma literatura nos trópicos, de 1978, primeira coletânea de ensaios de Silviano Santiago, observando que se trata da emergência de um ponto de vista pós-colonial para investigar a literatura. Para tanto, sustenta que a diferença como valor crítico e heurístico é afirmada por Santiago por meio do caráter relacional e violento da colonização. Para desdobrar essa hipótese de leitura, o texto promove uma análise que situa o debate sobre a diferença no interior da discussão sobre a dependência para, em seguida, discutir o estatuto teórico-metodológico do conceito de “entre-lugar”, destacando os principais aspectos do método crítico proposto pelo autor, bem como explorando algumas de suas consequências.
Um livro por vir: autobibliografia(s) de Silviano Santiago
Authors: Maciel Emílio
Published: April 2020

Leitura de Uma literatura nos trópicos, de Silviano Santiago, esse ensaio explora as tensões entre dito e implicado na arquitetura do livro, tomando como ponto de partida, de um lado, certos ecos telescópicos ligando algumas passagens decisivas, e de outro, a invisível teia de reverberações criada por tais ecos ao longo de todo o volume. Ao mesmo tempo, ao destacar a curiosa mescla de reverência e transgressão que constitui essa prosa, traço evidente no modo como Silviano cita e exorbita autores como Antonio Candido e Jacques Derrida, procura-se demonstrar como, nesse livro fundador, a autoridade associada ao amplo e ousado escopo de sua assinatura caminha lado a lado com uma profunda e paciente atenção aos impasses e pontos cegos que perturbam, em nível molecular, todo e qualquer texto.
Convivência conflitiva
Authors: Melo Miranda Wander
Published: April 2020

Abordagem da obra de Silviano Santiago como ficção teórica mediante a perspectiva do entre-lugar, que busca descondicionar o leitor e o escritor, torná-los aptos a intervir livremente na tradição literária, submetida à desconstrução, que se manifesta enquanto pharmacon, desvelador das estruturas de dominação presentes nas oposições remédio/veneno, bem/mal, dentro/fora, palavra/escritura. Busca-se destacar, ainda, a natureza experimental dos textos ensaísticos ou ficcionais, em constante remissão mútua e mútua significação pelo deslizamento incessante do significante intra e intertextual.
Superastro: um dispositivo de observação e reflexão teórica da performance?
Authors: Magalhães Pinto Aline
Published: April 2020

O texto busca considerar criticamente a noção de superastro, presente no livro Uma Literatura nos Trópicos, de Silviano Santiago (1972), entendendo-a como um operador interpretativo que pode tornar possível um exercício de teorização no horizonte conceitual e fenomênico aberto pela performatividade e pelo modo temporal que a perpassa: a presença. A questão levantada é se a exuberante figura do superastro pode servir como dispositivo de observação e reflexão teórica da performance.
Determinantes probabilísticos del riesgo de deserción en las Universidades de Nariño y del Valle (Colombia) a partir de los registros establecidos por el Ministerio de Educación Nacional (2007-2017).

Published: April 2020

En el artículo se analizan los principales determinantes probabilísticos del riesgo de deserción en la población estudiantil de las Universidades de Nariño y del Valle, Colombia, a partir de la clasificación hecha por el Sistema para la Prevención de la Deserción en las Instituciones de Educación Superior (Spadies), con riesgo de abandono medio y medio alto en la escala valorativa. El fundamento metodológico de tipo analítico parte de la estimación de un modelo probit, con variable discreta dependiente dicotómica “grupo de riesgo” y varias regresoras continuas y discretas. En los resultados se determina el perfil del estudiante con mayor riesgo de deserción en las dos universidades representado por sujetos hombres adscritos a la Facultad de Ciencias Exactas y Naturales, que no disponen de apoyos financieros dentro de la universidad donde se adscriben. Se concluye que la deserción, además de afectar al estudiante como ser social, incide en forma negativa en el desempeño de las instituciones de educación superior por su corresponsabilidad en la formación de un ciudadano integral.

Bu çalışmada, Şanlıurfa ili Karacadağ bölgesinde küçük süt işletmelerinde üretilen Şanlıurfa sadeyağı ile Tulum yağının (Runı hiz) bileşimi, bazı yağ indisleri, renk, biyokimyasal ve tekstürel parametreleri araştırılmıştır. Yapılan istatistiksel değerlendirmede, Şanlıurfa sadeyağına oranla, Tulum yağının ortalama yağ oranı, iyot sayısı, serbest asitlik, asit değeri ve peroksit değeri yüksek, nem oranı, kolesterol miktarı, su aktivitesi, L* değeri ve indüksiyon süresi ise daha düşük bulunmuştur (P<0.05). Depolama sıcaklığının yüksek olması nedeniyle Şanlıurfa sadeyağı ile Tulum yağının oksidasyon parametreleri yüksek bulunmuştur. Ayrıca, Şanlıurfa sadeyağı ve Tulum yağının bileşimi ve tekstürel parametreleri geniş bir aralıkta değişim göstermiştir. Bu nedenle, depolama sıcaklığı ve sadeyağ üretim yöntemi optimize edilmeli, ayrıca Tulum yağı üretiminde deri tulum kullanımı ile ilgili bilimsel çalışmalar yapılmalıdır. Alternatif ambalaj malzemesi olarak deri tulumun teknolojiye kazandırılması bölge ekonomisine katkı sağlayacağı düşünülmektedir.

Published: April 2020

The building sector is the largest consumer of the primary sources of energy worldwide. The most
commonly used primary sources of energy to generate electricity are oil, coal, peat, shale, natural gas, nuclear,
hydro, renewables, biofuels, and waste. The energy demand by the building sector is about 40% of the world’s
energy production.Net Zero Energy Buildings (NZEBs) is the best solution recommended by the energy experts
to reduce substantial pressure on primary sources of energy contributed by the building sector. There is a
marginal gap between estimates made during the design stage and actual energy performance of residential
buildings, primarily due to a lack of understanding of the factors affecting energy use and whole building
simulations software limitations. The purpose of this research work was to conduct a comparative analysis of a
predicted versus actual energy consumption of prototype Net Zero Energy Building (NZEB) constructed at
Higher College of Technology, Muscat. Hourly Analysis Program (HAP V4.2) was used to predict energy
demand of NZEB at HCT and same size regular house in Muscat. PVWatts calculator was used to determining
possible power generation by the PV system installed on the roof in the form of a canopy. The constructed house
was tested for one month to perform multiple tasks as per competition requirements in which one of the major
tasks was to produce onsite energy production by PV panel’s equivalent to the energy consumed by the house.
The actual energy consumption results were compared with the simulated result and observed that actual energy
demand of house was approximately 20% lower than that predicted by the simulation tool. The comparison of
simulation results between NZEB and regular house indicated 61.24 % less energy demand of NZEB, mainly
due to less HVAC load. The simulation result for BEI of NZEB showed 87.20 kWh/m2/year as compare to 225.1
kWh/m2/year for same size regular house. The simulated result obtained from PVWatts calculator for
competition period and actual production of an installed PV system at the top roof showed a minor deviation of
0.73% only. It is also observed from the results during the competition period house exported 1221 kWh energy
to the grid.

Published: April 2020

The current study aimed at investigation of the Variable Refrigerant Flow (VRF). Energy, exergy, and economic model for R11, R22, and R134a refrigerants. The genetic algorithm was used for optimization of the cycle. The objective functions in the current study were the second law efficiency and cooling cost. The cooling cost was a new economic function that was defined in this paper for the first time. Results showed that the highest Coefficient of Performance (COP) and second law’s efficiency as well as the lowest cooling cost and exergy loss belonged to the refrigerant R134a, and second and third to it were R11 and R22. The optimum values of condenser pressure and evaporators 1, 2, and 3 for the refrigerant R134a were 799.7, 706.2, 925.2, and 23122 (kPa), and the mass discharge of the evaporators 1 and 2, was 0.1 and 0.072 (kg/s).
MULTIFLUID DESCRIPTION OF RAREFIED GAS MIXTURE FLOWS
Authors: ZAHMATKESH Iman , EMDAD Homayoun , ALİSHAHİ Mohammad
Published: April 2020

In the present contribution attention is focused to extend the application of multifluid descriptions to rarefied conditions for the first time. To this aim, a multifluid Maxwell model and a multifluid Smoluchowski model are proposed for near wall behavior of the constituents of a rarefied gas mixture. Afterwards, multifluid balance equations in conjunction with these boundary conditions are solved for some slip flows of binary gas mixtures between parallel plates. The corresponding results are compared with those of a previously developed Navier–Stokes solver. Inspection of the results indicates that while the Navier–Stokes equations may lose their accuracy under high rarefaction, non–equilibrium features are properly captured by developed multifluid description. This successful method is thereafter utilized to discuss the consequences of velocity–slip, the tangential–momentum–accommodation coefficient, and mass disparity of the mixture constituents on the degree of non–equilibrium between the constituents of the gas mixtures between parallel plates.

A NARRATIVE INQUIRY ON HOW TEACHER PROFESSIONAL IDENTITY INFLUENCES TEACHER’S SCHOOL TYPE PREFERENCE
Authors: Rosari Maria Dewi
Published: April 2020

Some Indonesian English teachers prefer teaching in formal schools while some others favor non-formal schools more. This preference can be analyzed from the lense of teacher professional identity. In this study, the researcher tried to find out how teacher professional identity influences the school type teachers favor more. By conducting in-depth interviews to two non-formal school teachers from different regions in Indonesia, the researchers found out that job satisfaction, self-efficacy, occupational commitment, and occupational motivation are the factors influencing the participants’ professional identity the most. Job satisfaction could be seen, for example, in witnessing students’ progress more thoroughly; self-efficacy in being able to monitor their teaching performance; occupational commitment in teacher trainings provided by non-formal schools to build their career up; and occupational motivation in receiving manageable challenges from non-formal schools that trigger eagerness from the participants to work. Those findings could function as a reference for both formal and non-formal school stake holders in making sure that their schools could accommodate their teachers’ need in constructing their professional identity as it could influence teachers’ performance a lot.
Measuring Mastery Behaviors at Scale: The Persistence, Effort, Resilience and Challenge-Seeking Task (PERC)
Authors: Porter Tenelle , Catalán Molina Diego , Blackwell Lisa , Roberts Sylvia , Quirk Abigail , Lee Duckworth Angela , Trzesniewski Kali
Published: April 2020

Mastery behaviours — seeking out challenging tasks and continuing to work on them despite difficulties — are integral to achievement but difficult to measure with precision. The current study reports on the development and validation of the computer-based persistence, effort, resilience, and challenge-seeking (PERC) task in two demographically diverse samples of adolescents (total N = 3,188). We present evidence for convergent validity with self-reported mastery behaviours and learning mindsets, discriminant validity from theoretically unrelated constructs, and incremental predictive validity for grade point average (GPA). Results suggest that the PERC task may be a useful tool for assessing mastery behaviours at scale.
Magic apples and talking frogs: fairy tales in the Mayse-bukh
Authors: Rosenzweig Claudia
Published: April 2020

Among the surviving collections of Yiddish stories from the early modern period, the
Mayse-bukh
(Book of Stories) is the best known. During the same time, Italian collections of
novelle
and
fiabe di magia
(stories of magic) were printed in Italian and translated into other European languages, enjoying wide popularity. In this article I wish to demonstrate how the
editio princeps
of
Mayse-bukh
(Basel, 1602), some of its stories already in circulation in Hebrew and Yiddish manuscripts, included fairy tales that were read as such. Readers turned to the ‘Book of Stories’ that offered not only didactic and moral teachings and rabbinic
exempla
, but also the enchantment offered by a recognizible fictional dimension.
The Disraeli family and the history of the Jews
Authors: Goodman Martin
Published: April 2020

One of the illustrated Victorian editions of Whiston’s translation of Josephus, printed in London in 1848, contains ‘a Sequel to the History of the Jews; continued to the present time’. The title page gives no indication of the origins of this Sequel, which comprises a substantial history of the Jews from the first century CE to the nineteenth century. This article discusses the reasons to suppose that the Sequel was composed by the literary historian Isaac D’Israeli and completed rapidly after his death by his children, Benjamin Disraeli and his sister Sarah. The composition and publication history of the Sequel shed light both on the Jewish identity of Isaac and on the complex attitude of Benjamin to the public debates on Jewish emancipation, in which he intervened dramatically for the first time in December 1847.
El gallego y el castellano en contacto: code-switching, convergencias y otros fenómenos de contacto entre lenguas

Published: April 2020

Las lenguas acompañan al hombre en su día a día prácticamente desde siempre describiendo realidades y creando unas totalmente nuevas, pero las lenguas en sí mismas son unas creaciones fascinantes que se desarrollan, cambian, se transforman y se actualizan por medio de sus hablantes. El contacto entre lenguas crea, además, unos fenómenos que demuestran una gran capacidad de los usuarios de adaptar y/o adoptar las estructuras gramaticales, de inventar vocablos nuevos y de unir dos lenguas en una. […] El presente libro trata la cuestión del contacto entre dos lenguas muy próximas geográfica y tipológicamente que son el gallego y el castellano. La relación que tienen es bastante compleja siendo el gallego la lengua minorizada por la influencia de la lengua oficial en España que es el castellano.

The influence of abiotic and biotic disturbances on the protective effect of alpine forests against avalanches and rockfalls
Authors: Oven Domen , Žabota Barbara , Kobal Milan
Published: April 2020

Abiotic and biotic disturbances in alpine forests can reduce forest cover or change the structure of the forest and consequently reduce the protective effect of forest against natural hazards such as avalanches and rockfalls. In this review article, the effect of the main abiotic (forest fire, windthrow, ice break, snow break, avalanche and rockfall) and biotic (insects and pathogens) disturbances in protection forests are presented along with their potential influence on the protective effect of forest against avalanches and rockfalls. In general, natural disturbances negatively affect the protective effect of forest, especially in the case of large-scale and severe events, which in alpine areas are mostly caused by storms, bark beetle outbreaks, avalanches and forest fires. Climate change induced interactions between disturbances are expected to present challenges in the management of protection forests in the future.
A propósito de la oposición formal/material: cuatro aproximaciones interdisciplinares sobre un mismo tema = On the formal/substantive opposition: four interdisciplinary approaches on the same subject
Authors: Roales Buján Oliver
Published: April 2020

Resumen : El pensamiento cientifista moderno que pretende obtener certezas mediante la búsqueda de afirmaciones indiscutibles sobre hechos irrefutables derivados de la protocolización y estandarización de procedimientos que nos alejen del debate sobre los valores e intereses particulares, ha olvidado que la formalización que requiere el diseño de todo procedimiento aplicable a casos concretos supone siempre la incorporación de finalidades relativas a valores e intereses. Este olvido, propio del pensamiento moderno, se ha visto acompañado de otra actitud: la hiperespecialización de las disciplinas, de manera que sus consecuencias y los debates sobre las mismas en una especie de constante reinvención de la rueda se han reproducido estérilmente. Mediante un estudio interdisciplinar que pone de manifiesto las líneas comunes en debates paradigmáticos en los campos del derecho, la retórica, la lingüística, la ciencia cognitiva y la inteligencia artificial simbólica, así como la teoría política, pretendemos poner de manifiesto la incapacidad de las teorías procesualistas de satisfacer esa aspiración de certeza y neutralidad absoluta propia de las sociedades postmetafísicas en sentido habermasiano.Palabras clave: Debido proceso, debido proceso sustantivo, inteligencia artificial simbólica, filosofía política, J.Rawls, J. Habermas, C. Mouffe. Abstract :The modern scientificist thought that seeks to obtain certainty through the search for indisputable statements about irrefutable facts derived from the protocolization and standardization of procedures that take us away from the debate on particular values and interests, has forgotten that the formalization required for the design of any procedure applicable to specific cases always involves the addition of purposes related to values and interests. This oversight, typical of modern thought, has been accompanied by another attitude: the hyperspecialization of the disciplines, so that its consequences and the debates about them in a kind of constant reinvention of the wheel have been reproduced sterilely. Through an interdisciplinary study that highlights the common lines in paradigmatic debates in the fields of law, rhetoric, linguistics, cognitive science and symbolic artificial intelligence, as well as political theory, we intend to emphasize the inability of processual theories to satisfy an aspiration of absolute neutrality typical of postmetaphysical societies in the Habermasian sense. Keywords: Due process, substantive due process, symbolic artificial intelligence, political philosophy, J. Rawls, J. Habermas, C. Mouffe.
Obligación contractual = Contractual obligation
Authors: Gutiérrez Aguilar Ricardo
Published: April 2020

Resumen: El presente trabajo se plantea los interrogantes tanto legales como morales a que una teoría del contrato –y de su equivalente deóntico, la promesa– aboca. Encontramos esta doble naturaleza de las obligaciones legales ya desde los tiempos del derecho romano clásico, pero no es sino desde los años 80 que el tema ha experimentado una segunda vida académica. Con el advenimiento de la llamada muerte del contrato, los teóricos de la materia han discutido si el derecho civil no debería reabsorber la teoría general sobre el contrato como disciplina independiente, y reducir su componente moral. Las obras de Charles Fried y de Patrick Atiyah, reivindicando un compromiso moral fuerte en el ejercicio de la teoría y práctica jurídica de la promesa han abierto el camino a la actualidad del debate y presentado una alternativa a la exitosa teoría económica del contrato. Palabras clave:Obligación, contrato, promesa, teorías económicas del contrato, teorías deónticas del contrato Abstract: The aim of present article is to lay out the usual legal and moral enquiries to which a theory of contract –and its deontic equivalent, promise– leads. We can assess this dual nature of legal obligations even in classic Roman Law times, but it is not until the 80s that the issue has experienced a second academic life. With the sudden rise of scholarship around the so-called death of contract, theorists on the subject have discussed if would not be more convenient to reabsorb the general theory of contract as an independent discipline within tort law, reducing in this exercise its moral component. Charles Fried’s and Patrick Atiyah’s work vindicating a strong moral commitment in legal theory and practice through the underlying idea of promise has left opened the trail to contemporary debate and offered an alternative to the otherwise successful economic theory of contract. Keywords: Obligation, contract, promise, economic theories of contract, deontic theories of contract

Um Afrodisíaco Potencialmente Fatal: Intoxicação por Cantaridina
Authors: Diaz Priscila , Carneiro António , Montes Vera , Alves Sara
Published: April 2020

A cantaridina é uma toxina extraída de coleópteros, comummente conhecidos como ‘Spanish fly’. Historicamente utilizada como afrodisíaco, vesicante e abortivo. A intoxicação por este agente encontra-se amplamente descrita, tipicamente com envolvimento das mucosas gastrointestinal, com hemorragia digestiva, e genitourinária, com hematúria e lesão renal aguda. Os autores apresentam o caso de um doente do sexo masculino, com 51 anos que desenvolveu um quadro de intoxicação aguda por cantaridina, após ingestão de uma preparação (‘chá’) desta substância, com ardor na cavidade oral, diarreia, disúria, hematúria, lesão renal aguda e com um quadro neurológico atípico. A toxicidade pela cantaridina é sistémica, contudo, o envolvimento neurológico é raro. Dada ausência de um antídoto, preconiza-se a terapêutica de suporte. Este caso reforça a importância de uma anamnese detalhada, incluindo a utilização de produtos ‘naturais’ ou de ervanária (i.e. de origem não controlada), e da necessidade de alertar os doentes para a sua potencial toxicidade.
Consumption of Alcohol and Drugs in the School Population of Sao Tome and Principe
Authors: De Santiago Isabel , Ribeiro Ruy , Nicolau Leonor Bacelar , Marinho Rui Tato , Pereira-Miguel José
Published: April 2020

Introduction: In Sao Tome and Principe there are no studies on alcohol and drug use among students, who could be potential allies in preventive interventions. The objectives of the present study are 1) to determine the frequency of alcohol and drug consumption in the school population, and 2) to identify the main characteristics associated with this behaviour.Material and Methods: We applied a biographical, demographic and socioeconomic questionnaire on the use of licit and illicit substances to a sample of 2064 students. Demographic and social characteristics are presented based on observed frequencies and comparisons between groups were made using chi-square tests. Significance was assessed at α = 0.05.Results: More than half of the students reported consumed alcohol at least once in their lifetime, and 32% consumed in the last 30 days. Older students were more likely to consume alcohol (p < 0.0001), but even in students under 16 years, 17% consumed in the last 30 days. We also found that 7% consumed one or more times per week in the last 30 days. The reasons presented for frequent consumption were different for boys (“participation in their group of friends”) and girls (“decrease anxiety”) (p = 0.005). Less than 1% of respondents admitted to having used marijuana, cocaine, crack or ecstasy.Discussion: Despite some limitations, such as self-reporting, we provide a first overview showing high consumption of alcohol by young people and the existence of illegal drugs circulating in the schools.Conclusion: It is urgent to implement preventive interventions, namely in the context of public health communication.
Translation, Cultural Adaptation and Validation of the Current Opioid Misuse Measure for European Portuguese
Authors: Mendes-Morais Diogo , Jantarada Cláudia , Guimarães-Pereira Luís
Published: April 2020

Introduction: Current practice guidelines recommend using Current Opioid Misuse Measure to screen aberrant opioid-related behaviors in chronic pain patients. Our aims were to translate, adapt and validate it to be used in Portuguese chronic pain patients.Material and Methods: Translation and cultural adaptation process followed guidelines and a model of principles for good practice. Adult chronic pain patients on opioid therapy, from one major hospital in Portugal, were invited to complete the translated version. Descriptive statistics, Cronbach’s alpha, inter-item, item-total and intra-class correlation coefficients and principal components analysis were applied.Results: Translation process was performed as planned and the validation sample was composed by 98 patients (median age = 62.5 years). Regarding internal consistency, a global Cronbach’s alpha of 0.778 was obtained and item-total correlations of all items were above 0.20 with four exceptions. An intra-class correlation coefficient of 0.90 was found between test and retest. Regarding validity, all 17 items presented a content validity index above 0.80. Six principal components were extracted and explained 66.3% of the variance.Discussion: The Portuguese version of Current Opioid Misuse Measure was properly translated, adapted and validated; showing good quality in terms of reliability and validity. This is the first instrument to screen aberrant opioid-related behaviors in Portuguese chronic pain patients. Consequently, it will aid and promote the identification of opioid misuse in these patients.Conclusion: The implementation of this questionnaire may reduce the incidence and morbimortality of opioid misuse among chronic pain patients and should improve chronic pain treatment in Portugal.

A Pragmatic Approach to the Design of Advanced Precision Terrain Aided Navigation for UAVs and Its Verification
Authors: Lee Jungshin , Sung Chang-Ky , Oh Juhyun , Han Kyungjun , Lee Sangwoo , Yu Myeong-Jong
Published: April 2020

Autonomous unmanned aerial vehicles (UAVs) require highly reliable navigation information. Generally, navigation systems with the inertial navigation system (INS) and global navigation satellite system (GNSS) have been widely used. However, the GNSS is vulnerable to jamming and spoofing. The terrain referenced navigation (TRN) technique can be used to solve this problem. In this study, to obtain reliable navigation information even if a GNSS is not available or the degree of terrain roughness is not determined, we propose a federated filter based INS/GNSS/TRN integrated navigation system. we also introduce a TRN system that combines batch processing and an auxiliary particle filter to ensure stable flight of UAVs even in a long-term GNSS-denied environment. As an altimeter sensor for the TRN system, we use an interferometric radar altimeter (IRA) to obtain reliable navigation accuracy in high altitude flight. In addition, a parallel computing technique with general-purpose computing on graphics processing units (GPGPU) is applied to process a high resolution terrain database and a nonlinear filter in real time on board. Finally, we verify the performance of the proposed system through software-in-the-loop (SIL) tests and captive flight tests in a GNSS unavailable environment.

Are Qualia Reducible, Physical Entities?
Authors: Kerskens Christian Matthias
Published: April 2020

Controversial hypotheses to explain consciousness exist in many fields of science, psychology and philosophy. Recent experimental findings in quantum cognition and magnetic resonance imaging have added new controversies to the field, suggesting that the mind may be based on quantum computing. Quantum computers process information in quantum bits (qubits) using quantum gates. At a first glance, it seems unrealistic or impossible that the brain can meet the challenges to provide either of these. Nevertheless, we show here why the brain has the incredible ability to perform quantum computing and how that may be realized.

Background: Besides anemia, iron deficiency may cause more subtle symptoms including those of the restless legs syndrome (RLS), the chronic fatigue syndrome (CFS) or sleeping disorders. Objective: The aim of this pre-planned secondary analysis was to compare the frequency and severity of symptoms associated with iron deficiency before and after (intravenous or oral) iron supplementation in iron deficient blood donors. Methods/Design: Prospective, randomized, controlled, single centre trial. (ClinicalTrials.gov: NCT01787526). Setting: Tertiary care center in Graz, Austria Participants: 138 female and 38 male whole blood and platelet apheresis donors aged ≥18 and ≤65 years with iron deficiency (ferritin ≤30ng/ml at the time of blood donation). Interventions: Intravenous iron (1 g ferric carboxymaltose, n=86) or oral iron supplementation (10 g iron fumarate, 100 capsules, n=90). Measurements: Clinical symptoms were evaluated by a survey before iron therapy (visit 0, V0) and after 8-12 weeks (visit 1, V1) including questions about symptoms of RLS, CFS, sleeping disorders, quality of life and symptoms like headaches, dyspnoea, dizziness, palpitations, pica and trophic changes of fingernails or hair. Results: We found a significant improvement in the severity of symptoms for RLS, fatigue and sleep quality (p<0.001). Furthermore, a significant decrease of headaches, dyspnoea, dizziness and palpitations was reported (p<0.05). There was no difference between the type of iron supplementation (intravenous versus oral) and clinical outcome data. Conclusion: Iron supplementation in iron deficient blood donors may be an effective strategy to improve symptoms related to iron deficiency and the wellbeing of blood donors.

Artemia franciscana, native to America, has recently colonized non-indigenous populations in Eurasia, Mediterranean regions and Australia. In present we sought to evaluate the potential effects of colonization of A. franciscana on genetic differentiation in the new environments in UAE. We used the COI marker to determine population genetic structure and identify the origins of exotic populations in UAE. Our findings have confirmed the colonization of both localities by A. franciscana. Genetic variation of invasive A. franciscana were exclusively lower than native population in Great Salt Lake and San Francisco Bay. Results have showed the studied population could not possibly have colonized directly from natural American localities, perhaps resulting from secondary introduction events from other non-indigenous populations. Genetic analysis have yielded different demographic patterns for invasive studied populations. Al Wathba Wetland Reserve (AWWR) population have represented demographic expansion. In contrast, Godolphin Lakes (GL) population was at demographic equilibrium. Neutrality tests have documented the excess of both recent and historical mutations in the COI gene pool of invasive AWWR Artemia throughout establishment in the new environment.

This paper presents several novel designs of underwater portable radio antennas operating in the 2 MHz, 50 MHz and 2.4 GHz bands and efficient for launching surface electromagnetic waves at the seawater/air interface. The antenna operation is enabled by an impedance matching antenna enclosure, which is filled with de-ionized water. Enhanced coupling to surface electromagnetic waves is based on the field enhancement at the antenna tip. These design features allow us to reduce antenna dimensions and improve the coupling of electromagnetic energy to the surrounding saltwater medium. Since surface wave propagation length far exceeds the skin depth of conventional radio waves at the same frequency, this technique is useful for broadband underwater wireless communication over distances, which far exceed the skin depth in seawater. We conclude that the developed broadband underwater radio communication technique will be useful in networking of unmanned underwater vehicles.

The use of concrete material which dominates Indonesian construction industry is not only because its compilers are easy to get, but also because it has high durability. Anyhow, concrete structure might have high risk of damage in aggressive region and open space. Sulfate attack will form calcium sulfoaluminate where the volume of calcium aluminate is higher than concrete’s, so its volume increases and damages the connection between aggregate and cement which work as bonding. One of applicative and easy-to-get technology in preventing the effect of sulfate attack is by using additional material, pozzolan. It consists of fly ash and Blast Furnace Cement BFC which come from iron ore refining process. This research aims at finding out the effect of sea water in immersion phase and age variation towards compressive strength, split strength, flexural tensile strength and concrete permeability as well as the depth of chloride ion infiltration in normal concrete by adding fly ash. Chloride ion infiltration testing is done by soaking 150x150x150 mm cube using sea water with various period for 28, 60 and 90 days and then it will be sprayed by AgNO3 solution to know the depth of absorbed chloride ion infiltration. Chloride ion infiltration of concrete using sea water happens in 0-1.4 cm depth up to 90 days management. The addition of fly ash 12.5% makes the depth of chloride ion infiltration become smaller than using OPC for each immersion age variation.

Bendungan merupakan bangunan atau infrastruktur sumber daya air yang sangat penting yang mempunyai fungsi dan manfaat untuk memenuhi berbagai kebutuhan bagi  kehidupan dan penghidupan manusia, selain memberikan manfaat  yang  demikian  besar,  perlu disadari bahwa bendungan juga mengandung potensi  resiko terjadinya bencana apabila terjadi kegagalan atau keruntuhan bendungan. Perlu diketahui bahwa banyak bendungan di Indonesia mengalami kerusakan dan penurunan fungsi, kinerja dan keandalannya yang antara lain disebabkan oleh faktor internal dan eksternal. Salah satu bendungan yang perlu diperhatikan karena faktor umur bendungan itu sendiri adalah Bendungan Cengklik. Bendungan Cengklik  dibangun  oleh  Pemerintah  Belanda  mulai  tahun  1923  dan selesai pada tahun 1931. Penilaian kondisi bendungan diperlukan untuk mengetahui tingkat keamanan bendungan dan sebagai bahan pertimbangan untuk kegiatan rehabilitasi bendungan. Berdasarkan permasalahan tersebut diatas maka perlu dilakukan penilaian kinerja Bendungan Cengklik. Metode yang digunakan pada penelitian ini adalah metode Analytic Network Process (ANP) dengan bobot skala prioritas mengacu pada Pedoman Penilaian Kondisi Fisik Bendungan serta menggunakan software Super Decision sebagai alat bantu analisis Berdasarkan hasil penilaian ANP dengan menggunakan bantuan aplikasi Super Decision, dapat disimpulkan bahwa Bendungan Cengklik memiliki nilai B, yang berarti Bendungan Cengklik memiliki kondisi rusak ringan jika nilai kondisi 80–90% dan nilai tingkat kerusakan 10–20% dari kondisi awal bangunan.

Cookies are processed cakes made from wheat flour. However, currently the need for flour is mostly met with import activities, so there needs to be an effort to reduce dependence on the use of wheat flour. One of the local food resources that can be used as an alternative to flour is cocoyams flour (Xanthosoma sagittifolium) which was modified by the fermentation process using the starter Lactobacillus plantarum to improve product texture. Tapioca can also be used as a substitute for wheat flour in making cookies, while the formation of texture can be helped by the addition of margarine. This study aimed to determine the effect of the proportion of cocoyams flour: tapioca flour and the addition of margarine to the characteristics of cookies. This research used factorial completely randomized design with two factors. The first Factor is proportion of modification cocoyams flour and   tapioca (50:50, 60:40, and 70:30). The second factor in the form of concentration addition of margarine (50%, 60%, 70%). The results showed that the best treatment was the proportion of modification cocoyams and tapioca flour (70:30) and the addition of 50% margarine which produced cookies with criteria of water content of 3.95%, fat content of 29.15%, crude fiber of 3.29%, fracture strength of 11.17 N, yield of 55.95%, and organoleptic test results with the number of ranks of preference level for crispness/texture of 139, aroma 110.5, color 106 and taste 133.8

Background: The coexistence of polycyclic aromatic hydrocarbons (PAHs) and heavy metals has deleterious effects on environmental quality. Few reports have studied the mechanisms of plant inoculation with Piriformospora indica to remediate PAH-metal co-contaminated soil by analyzing the chemical speciation of the contaminants. This study investigated the influence of the inoculation of Medicago sativa with P. indica to remediate soil co-contaminated with phenanthrene (a kind of PAH) and cadmium (a heavy metal) by analyzing plant growth, physiological parameters and chemical speciation in rhizosphere and nonrhizosphere soils. Results: The presence of P. indica significantly increased plant tolerance, chlorophyll a, chlorophyll b, maximum quantum efficiency of PSII photochemistry and electron transport rate values in phenanthrene- and/or cadmium-contaminated soil. P. indica inoculation in M. sativa roots increased fluorescein diacetate activities in soils contaminated with phenanthrene, cadmium or both, especially in the nonrhizosphere. The presence of phenanthrene prevented the inoculated plant from accumulating cadmium to some extent, whereas the presence of cadmium did not prevent the degradation of phenanthrene in either the rhizosphere or the nonrhizosphere after P. indica colonization. Although the low bioavailability of cadmium in the rhizosphere restricted its transportation into the stem, P. indica colonization in plants effectively increased cadmium accumulation in roots in soil co-contaminated with cadmium and phenanthrene. Conclusions: In conclusion, this work provides a theoretical basis for the use of P. indica combined with M. sativa for the remediation of PAH-metal co-contaminated soil.
