Sugarcane is nowadays considered an important source of energy. One of its products is sugarcane bagasse. Bagasse is largely used as a boiler fuel. The goal of this work was to study bagasse drying in a fixed bed and its desorption isotherm. Air was used as drying agent at 40, 50 and 60 ºC at flow rate of 0.9 m s-1. Desorption isotherms were also obtained at 40 and 50 ºC. Several models from literature were tested with regards to their fit to fixed bed drying and desorption isotherm data. The best adjustments were obtained with Modified Page 2 model for drying kinetics and both the Jaafar and Michalowski model and modified Henderson 2 model for the desorption isotherm.

Conhecer a distribuição das chuvas ao longo do tempo é fator determinante para quantificar a disponibilidade de água. Com este trabalho, objetivou-se realizar a análise do comportamento da precipitação pluvial mensal nas cinco regiões político-administrativas do Brasil, e também fazer a comparação anual e mensal do comportamento das precipitações médias considerando dados obtidos das normais climatológicas (1961 a 1990) e de séries históricas de estações pluviométricas (1990 a 2012) para as capitais brasileiras. A partir desses dados, foram gerados gráficos de distribuição da precipitação média mensal. Com relação às variações obtidas para diferentes séries históricas e diferentes quantidades de anos analisados, obteve-se um comportamento semelhante quanto à forma da distribuição do regime pluviométrico ao longo do ano. Observou-se também que existe um comportamento diferente com relação à precipitação média mensal nas regiões político-administrativas do Brasil, sendo uma distribuição homogênea constante, referente à região Sul; um comportamento simétrico e unimodal, referentes às regiões Sudeste, Norte e Centro-oeste; e um comportamento simétrico bimodal, referente à região Nordeste.

A agricultura na região Oeste do Paraná tem destaque por intensa atividade agrícola, na qual busca altas produtividades. A produtividade das áreas de cultivo está diretamente relacionada com a fertilidade. O uso intensivo do solo tende à acidificação e diminuição nos teores de nutrientes nele armazenados, o que, por consequência, limita também o desenvolvimento radicular, contribuindo para redução da produtividade. O presente trabalho foi desenvolvido com o intuito de investigar a relação entre as propriedades químicas do solo: acidez potencial, cálcio, magnésio, potássio, pH do solo, teor de matéria orgânica, soma de bases, capacidade de troca de cátions total e saturação por bases, na camada de 0,0 a 0,20 m. A exploração do solo na região se faz de forma intensiva com cultivos de soja, milho, trigo e feijão em sucessão de culturas. A amostragem de solo para análise das referidas variáveis foi georreferenciada (grid de 2 ha), sendo utilizadas técnicas de geoestatística e análise de componentes principais, com o intuito de identificar regiões que possuam maior acidez e deficiência de nutrientes que possam ser supridos por meio de calagem. Os resultados permitiram evidenciar a relação da acidez do solo com variáveis como cálcio e magnésio o que sugere a correção desses nutrientes nas regiões de elevada acidez. A classificação dos mapas em classes permite o direcionamento de ações em campo nas unidades com características similares, sendo importante para o trato localizado destas sub-regiões na área de estudo.

Published: November 2018

Objetivou-se, com o presente trabalho, avaliar a influência da velocidade de deslocamento na semeadura em relação à qualidade de distribuição longitudinal e à produtividade da soja. Foi avaliada uma semeadora múltipla com mecanismo dosador de disco horizontal com acionamento mecânico. O delineamento experimental foi realizado em blocos ao acaso, com 04 repetições, no qual foram avaliadas seis velocidades de deslocamento. As variáveis mensuradas foram: a distribuição longitudinal, espaçamentos múltiplos, falhos, aceitáveis e a produtividade de soja. O incremento na velocidade de deslocamento da semeadora interferiu nos espaçamentos falhos, múltiplos e aceitáveis. A produtividade reduziu com o aumento da velocidade.
MECHANISED HARVEST OF ENERGY WOOD: STATE-OF-THE-ART AND NEW DEVELOPMENTS
Authors: Pecenka Ralf , Silva Jadir Nogueira , Ehlert Detlef , Scholz Gerd Volkhard
Published: November 2018

Energy wood from fast growing trees, also called short rotation coppice (SRC) such as poplar, willow and eucalyptus, may provide a secure source of income for farmers, provided that production technologies, logistic chains and end user facilities are well designed in farmers’ regional structures. One of the key problems at present is the lack of inexpensive harvesting machinery. Analyzing the process chain of fast growing trees, chip lines seem to be most costefficient for harvest, and the modification of forage harvesters is a promising option. But the high machine weight of forage harvesters is a serious disadvantage for harvest in rain-laden or mountainous regions. Furthermore, for economic operation of these expensive harvest systems cultivation areas of more than 300 ha are required. Therefore, a simple and low weight tractor-mounted mower-chipper for medium sized standard tractors has been developed. The chipper is designed for flexible harvest of wood from fast growing trees (max. stem diameter 15 cm). The total weight of the harvester (tractor and chipper) is less than 50 % of the forage harvester combination resulting in much more flexible field operation and lower harvest costs. The machine has been successfully tested in the last three harvest seasons on an area of more than 110 ha. At harvest of 4 years old poplars (10 - 15 cm stem diameter) an average field performance of 0.5 ha h-1 has been realized. Due to the robust design and performance of the prototype the development of a reinforced model is considered at present. Such a new model could be designed for harvest of poplar or eucalyptus trees with stem diameters of more than 20 cm.

Authors: Maia Leonardo Rocha , Ferraz Samantha Pereira , Rodrigues Luciano Brito
Published: November 2018

Were analyzed the working conditions in a small feed mill, with identification of occupational risks (physical, chemical, biological, ergonomic and accidents) and measurement of noise levels. Data collection was performed qualitatively by using a survey, previously developed, as well as in loco observation. There was at least one factor belonging to the five occupational risks, and the ergonomic risk was associated with all activities. The feed mill assessed was not in accordance with the Regulatory Standards related to Health and Safety, and arrangements to adjust it accordingly must be taken. Corrective actions goes from the purchase and supply of appropriate personal protective equipment for worker to structural changes, such as installing handrails and repairing of electrical installations. These initiatives, if implemented could contribute to reducing the risks that affect the health and physical integrity, with opportunities to improve quality and productivity of the services performed.

O objetivo desse trabalho foi avaliar o desempenho energético, o rendimento na barra de tração e a eficiência de combustão em um motor de ciclo Diesel de um trator agrícola utilizando diferentes cargas na barra de tração e vazões de entrada de ar no sistema de alimentação. Assim, montou-se um experimento em delineamento inteiramente casualizado no esquema fatorial 5 x 4, constituído por diferentes cargas na barra de tração do trator (2,7; 7,4; 11,9; 15,5 e 20,5 kN) e diferentes vazões de ar admitida pelo motor (0,077; 0,085; 0,099 e 0,109 m3 s-1), com três repetições. A vazão de ar admitida pelo motor nas menores proporções, 0,077 e 0,085 m³ s-1, proporcionou aumento no consumo de combustível. O maior rendimento na barra de tração e o menor consumo específico de combustível ocorreram quando o trator tracionou a maior carga, 20,5 kN. A eficiência de combustão reduz com o aumento da vazão de ar admita para o motor.

Published: November 2018

The paper deals with production of above-ground biomass of silver birch ( Roth) stands in the Czech Republic. One-year biomass dynamics was studied within chronosequence of birch stands at the age of 4â5, 8â9, 17â18 and 22â23 years. With the exception of the youngest stand, which was established by seeding, all experimental birch stands were regenerated naturally after the allochthonous spruce stands. Above-ground biomass (AB) was calculated from plot inventory data and biomass equations were parameterized from destructive sampling of biomass component of sampled trees. Results reveal that the peak of the mean annual increment (MAI) of birch stands can be expected at the age from 15 to 20 years. Additionally, the stand age, the value of basal area (BA) should be considered as a predictor of stand productivity. If the value of BA varied from 25 to 35 m ha, the MAI of the birch stands reached the range from 5.0 to 6.5 t of dry biomass per ha y at the age ranging between 15 and 25 years. The stem/branch proportion increased with stand age, the stem relative proportion ranging from 75 to 90% of total above-ground biomass. According to the results of this study, birch stand biomass production and utilization is one of the approaches in terms of forest recovery management in large disturbed areas. Although, no silvicultural treatments were occurred in all analysed stands, the pre-commercial thinning method could increase stand productivity and stability as well.Betula pendulaABtotal2â1â1
The Role of the Clinical Educator in Teacher Preparation: An Exploratory Study of Perceptions of Preparedness
Authors: Driskill Kristen M.
Published: November 2018

As the demands on P-12 teachers increase, so do the demands on teacher preparation programs. In higher education institutions across the country, coursework is regularly updated to reflect changing academic standards, increasing diversity in classrooms, rigorous certification exams, etc. In addition, accreditation standards have been updated to reflect the need for P-12 partnerships in best preparing teacher candidates. As a result, clinical practice has come under focus. Yet the role of the clinical educator remains unclear. There is a gap in the literature regarding the preparedness and support of clinical educators, particularly addressing their role in developing teacher candidates along with higher education faculty. The assumption is that P-12 partners are prepared to co-construct experiences for teacher candidates. But, in specifically looking at clinical educators’ preparedness, there is a small research base. In response, this paper presents a quantitative study of clinical educators perceptions of their role in mentoring teacher candidates.
Where Do They Come From and How Can We Find More? Recruiting Teacher Candidates During Lean Times

Published: November 2018

Teacher preparation programs are facing an alarming drop in enrollments around the country. Our university, The State University of New York at Albany, has not been exempted from decreased enrollments. Low enrollments have led us to initiate direct attempts to recruit quality applicants to our master’s programs. As part of our overall recruiting plan, we created a survey of our applicants to determine how they discovered our programs and why they want to attend our programs so that we can better utilize our limited advertising resources. Survey results and implications for recruiting teacher candidates are discussed
Origins of Wilson’s Warblers migrating through southwest Canada: Adding value to banding data by using stable isotopes and genetic markers
Authors: Kardynal Kevin J. , Collister Douglas M. , Hobson Keith A.
Published: November 2018

Stopovers used by birds during migration concentrate individuals from broad geographic areas potentially providing important information on catchment areas of birds moving through these sites. We combined stable isotope (δ2H), genetic fingerprinting and band recovery data to delineate the molt origins of Wilson’s Warblers (Cardellina pusilla) migrating through a stopover site in southwestern Canada in the fall. We assessed changes in δ2Hf indicating latitudinal origins with ordinal date to show this species likely underwent leapfrog migration through this site. Using the combined approach to determine origins, Wilson’s Warblers migrating through southwestern Alberta in 2015 were mostly from the western boreal population (n = 155, 96%) with some individuals from the Pacific Northwest (n = 1, 0.6%), Rocky Mountain (n = 2, 1.2%) and eastern boreal (n = 3, 1.8%) populations. Our results suggest that individuals migrating through our study site come from a broad catchment area potentially from a large part of northwestern North America. Future studies should link population changes at banding stations with other information to determine associations with large-scale landscape-level drivers (e.g. climate, land use).
Danger of false negative (exclusion) or false positive (diagnosis) for ‘congenital thrombophilia’ in the age of anticoagulants
Authors: Favaloro Emmanuel J.
Published: November 2018

Background

Most guidelines and experts recommend against performance of thrombophilia testing in general, and specifically against testing patients on pharmacological anticoagulants, due to substantially increased risk of false positive identification. For example, vitamin K antagonist (VKA) therapy affects protein C (PC) and protein S (PS), as well as some clotting assays (e.g. as used to investigate activated PC resistance [APCR]). Although heparin may also affect clotting assays, most commercial methods contain neutralisers to make them ‘insensitive’ to therapeutic levels. Direct oral anticoagulants (DOACs) also affect a wide variety of thrombophilia assays, although most reported data has employed artificial in vitro spiked samples.

Methods

In the current report, data from our facility for the past 2.5 years has been assessed for all ‘congenital thrombophilia’ related tests, as evaluated against patient anticoagulant status. We processed 10,571 ‘thrombophilia’ related test requests, including antithrombin (AT; n=3470), PC (n=3569), PS (n=3585), APCR (n=2359), factor V Leiden (FVL; n=2659), and prothrombin gene mutation (PGM; n=2103).

Results

As expected, VKA therapy affected PC and PS, and despite manufacturer claims, also APCR. Most assays, as suggested by manufacturers, were largely resistant to heparin therapy. DOACs’ use was associated with falsely low APCR ratios (i.e. FVL-like effect) and somewhat unexpectedly, anti-Xa agents apixaban and rivaroxaban were also associated with lower AT and higher PS values.

Conclusions

It is concluded that ex-vivo data appears to confirm the potential for both false positive and false negative ‘thrombophilia’ events in patients on anticoagulant (including DOAC) treatment.
Harriet Tubman and Andrew Jackson on the Twenty-Dollar Bill: A Monstrous Intimacy
Authors: Thompson Sheneese , Barchiesi Franco
Published: November 2018

The controversy surrounding the announcement by the US Treasury, in April 2016, that the portraits of Harriet Tubman and Andrew Jackson will “share” the twenty-dollar bill-which the latter has embodied for almost a century-highlights a glaring incongruity: A formerly enslaved black woman and abolitionist leader is being placed in iconic proximity with an exemplary historical representative of the United States as a national experiment built on whiteness, slavery, and genocide. Our essay revolves around three basic questions: Why Tubman? Why Jackson? Why Now? The Treasury’s decision and its subsequent vicissitudes allow insights into the blurring of Barack Obama’s avowed “post-racialism,” which presided over the idea to redesign the currency, into the overt white supremacy and anti-black violence at the onset of the Trump regime, which has de facto frozen the implementation of the new bill. The story serves, namely, as a commentary on paradigmatic antiblackness as a force that, being constitutive of American civil society, has been fortified by the “post-racial” pretences of the Obama era. With reference to Christina Sharpe’s notion of “monstrous intimacy” and Saidiya Hartman’s theorization of “fungibility,” we argue that the twenty-dollar bill affair reflects the ways in which the interlocutory life of civil society is fortified by the continuous positioning, in popular imagination and discourse, of the black female body as inert matter in modes of appropriation, violence, and representation that sustain America’s political and libidinal economy.
The Lean In Collection: Women, Work, and the Will to Represent
Authors: West Caroline
Published: November 2018

In February 2014, Getty Images, the largest international stock photography agency, and LeanIn. org, Facebook COO Sheryl Sandberg’s women’s empowerment foundation, announced a new partnership that aimed to change the way women are portrayed in stock photography. The “Lean In Collection” with Getty seeks to challenge visual gendered stereotypes ascribed to both sexes in the daily life of work, home, and family life in advertising imagery. While the overarching ambition of gender empowerment implicit in the mission of Lean In is a worthwhile goal, I look to the problematic relationship rooted in the partnership between Lean In’s gender empowerment initiative and the role of Getty Images in trafficking aesthetic stereotypes for profit. Using methods of visual analysis and feminist critique, I argue that the photographs idealise a concept of female empowerment that is steeped in the rationale of neoliberal economics, which narrowly circumscribes gender citizenship according to the mandates of market logic. The Lean In Collection describes gender equality not as a right of citizenship procured by the state, but as a depoliticised and individualised negotiation.
What we talk about when we talk about space and narrative (and why we’re not done talking about it)
Authors: Parker Joshua
Published: November 2018

Narrative has often been considered “an art of time.” This essay traces some of the historical reasons for this state of the field, or fields, of narratology, pinpointing spots in classical, postclassical and contemporary narrative theory where compensation was attempted or is being made through a focus on space instead of time. It suggests that as geography and geographers have become increasingly interested in narrative approaches in dealing with concepts, visualization, and digitalization, it is perhaps (once again) time narratology itself, while continuing to focus on and explore space and place, took account of its history of treating them and looked at how geography has implemented narratological concepts in its technical and philosophical approaches.
Divergent theories, converging evidence: The constructional semantics of competing future constructions
Authors: Hartmann Stefan
Published: November 2018

This paper investigates the alternation between two competing German future constructions, the werden + Infinitive construction and the futurate present, from a usage-based perspective. Two lines of evidence are combined: On the one hand, a pilot corpus study indicates that werden + Infinitive is more likely to be used for referring to distant-future events than to near-future events. However, syntactic factors seem to be at least as decisive as semantic ones for speakers’ choice between the two constructions. On the other hand, an experimental study taps into language users’ interpretation of sentences framed in one of the two constructions. It can be shown that the grammatical framing does not significantly affect participants’ estimates of the temporal distance of the events to which the stimuli sentences refer. This suggests that the meaning differences between the two constructions be more nuanced, e.g. pertaining to discourse-pragmatic functions.
Idempotents, group membership and their applications
Authors: Porubský Štefan
Published: November 2018

Š. Schwarz in his paper [SCHWARZ, Š.:Zur Theorie der Halbgruppen, Sborník prác Prírodovedeckej fakulty Slovenskej univerzity v Bratislave, Vol. VI, Bratislava, 1943, 64 pp.] proved the existence of maximal subgroups in periodic semigroups and a decade later he brought into play the maximal subsemigroups and thus he embodied the idempotents in the structural description of semigroups [SCHWARZ, Š.:Contribution to the theory of torsion semigroups, Czechoslovak Math. J.3(1) (1953), 7–21]. Later in his papers he showed that a proper description of these structural elements can be used to (re)prove many useful and important results in algebra and number theory. The present paper gives a survey of selected results scattered throughout the literature where an semigroup approach based on tools like idempotent, maximal subgroup or maximal subsemigroup either led to a new insight into the substance of the known results or helped to discover new approach to solve problems. Special attention will be given to some disregarded historical connections between semigroup and ring theory.
Weak pseudo-BCK algebras
Authors: Ciungu Lavinia Corina
Published: November 2018

In this paper we define and study the weak pseudo-BCK algebras as generalizations of weak BCK-algebras, extending some results given by Cı⃖rulis for weak BCK-algebras. We give some characterizations of weak pseudo-BCK algebras and we prove that a weak pseudo-BCK algebra satisfying the right distribution laws is a BCK-algebra. We define the class of commutative weak pseudo-BCK algebras, and we give equivalent definitions and characterization theorems for commutative weak pseudo-BCK algebras. The classes of quasi pseudo-BCK algebras and weak pseudo-BCK(E) algebras are introduced and a characterization theorem for quasi pseudo-BCK algebras is given. We prove that any weak pseudo-BCK(E) algebra is a pseudo-BE algebra and the class of commutative weak pseudo-BCK(E) algebras is equivalent to the class of commutative pseudo-BCK algebras.

Local-periodic solutions for functional dynamic equations with infinite delay on changing-periodic time scales
Authors: Wang Chao , Agarwal Ravi P. , O’Regan Donal
Published: November 2018

In this paper, by using the concept of changing-periodic time scales and composition theorem of time scales introduced in 2015, we establish a local phase space for functional dynamic equations with infinite delay (FDEID) on an arbitrary time scale with a bounded graininess function μ. Through Krasnoseľskiĭ’s fixed point theorem, some sufficient conditions for the existence of local-periodic solutions for FDEID are established for the first time. This research indicates that one can extract a local-periodic solution for dynamic equations on an arbitrary time scale with a bounded graininess function μ through some index function.
Anglo-Saxon Studies in Heidelberg: Georg Jellinek, Max Weber and Ernst Troeltsch
Authors: Graf Friedrich Wilhelm
Published: November 2018

In the German Kaiserreich the University of Heidelberg was known as a liberal academic institution, with internationally well-known professors and many students from foreign countries. Young and innovative scholars in the institution included the Protestant theologian and philosopher Ernst Troeltsch (1865-1923), the sociologist Max Weber (1869-1920) and the Professor of Public Law Georg Jellinek (1851-1911) who studied the origins and driving forces of capitalism and of modern occidental rationalism. These scholars were interested in the ‛cultural significance’ of religious beliefs and their ethical implications. They saw religion as a relatively autonomous cultural force sui generis. In close intellectual interaction they focused on the religious roots of modern human rights and the strong ethical differences between Lutheranism and Calvinism.

Das Zusammenspiel zwischen Migration, Gesundheit und sozialer Lage ist durch verschiedene Wirkmechanismen gekennzeichnet. Die soziale Lage beeinflusst gesundheitliche Chancen und Risiken sowie die Migration selbst und trägt dazu bei, ob migrationsbedingte Einflüsse auf die Gesundheit verstärkt oder abgeschwächt werden. Migration ist bedeutend für die Erklärung gesundheitlicher Ungleichheit, obgleich Verzerrungen und Messartefakte bei Interpretationen berücksichtigt werden müssen.
Forming Diagnostic Opinions
Authors: Woerner Markus H. , Edmondson Ricca
Published: November 2018

Using an understanding of rhetoric as a method of communicative reasoning capable of providing grounds for conviction in those to whom it is addressed, this article argues that the formation of medical diagnoses shares a structure with Aristotle’s account of the rhetorical syllogism (the enthymeme). Here the argument itself (logos), together with characterological elements (ethos) and emotions (pathos), are welded together so that each affects the operation of the others. In the initial three sections of the paper, we contend, first, that diagnoses, as verdictive performatives, differ from scientific claims in being irreducibly personal and context-dependent; secondly, that they fit the structure of voluntary action as analysed by Aristotle and Aquinas; thirdly, that as practical syllogisms they differ from theoretical syllogisms, for example in taking effect in action, being ›addressed‹, and being intrinsically embedded in wider contexts of medical communication and practices. In the remaining sections we apply this account to textual evidence about diagnosis, drawing on work by the brain surgeon Henry Marsh. A rhetorical analysis of his observations on the formation of diagnostic opinions in situilluminates how moral, social and emotional features are fused with the cognitive aspects of medical judgement, making or marring how diagnoses and treatment are enacted. In other words, a philosophical- rhetorical account of diagnosis can help us to appreciate how medical diagnosis takes effect. We briefly conclude with some implications of our work for how diagnostic processes could in practice be better supported.
Wissenskonstitution durch Lösungsorientierte Fragen in psychodiagnostischen Gesprächen
Authors: Spranz-Fogasy Thomas , Kabatnik Susanne , Nikendei Christoph
Published: November 2018

Psychotherapy talk is characterized by epistemic, emotional and professional asymmetries of knowledge, which are continuously adjusted to by the participants in joint process of negotiation. Adjustment is based on structural features of communication: the fundamental sequentiality of verbal interaction, i.e. interrelated succession of utterances of at least two interlocutors, provides for and guarantees the achievement of intersubjectivity and therapeutic efficiency. Solution-oriented questions as a rhetorical practice serve to produce forward-looking awareness, expansion of knowledge and reorganization of knowledge on the patient’s side as well as an increased ability to act. These processes become apparent not only locally in the immediate context of solution-oriented questions but also globally in the course of the interaction as a whole. The data for this research consists of psychodiagnostic interviews conducted according to the concept and manual of the Operationalized Psychodynamic Diagnostics (OPD Task Force 2009).

In the present study, we have deposited hierarchical flower-like microstructured zinc oxide (ZnO) thin films directly on a glass substrate by using the simplistic aqueous chemical route for different concentrations of triethanolamine (TEA) which acted like a complexing agent. The as-synthesized ZnO thin films were subsequently annealed at 300 °C and are characterized with characterization techniques such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), photoluminescence (PL), and electrical resistivity. The hexagonal wurtzite crystal structure of as-synthesized ZnO thin films was confirmed by their XRD patterns and the well-resolved ZnO flowers-like morphology was revealed from the FESEM micrographs. From FESEM images it can be seen that the ZnO flower is composed of dozens of nanorods originating from the same core in a symmetric fashion with an average diameter of around 180-300 nm. The flower-like morphology was obtained at 0.3 M TEA concentration. Due to its hierarchical structure, the deposited ZnO thin films were employed for multiple applications such as gas sensing and anti-microbial activity. The ZnO thin films with micro-flowers like morphology showed the maximum gas sensor sensitivity ∼64.50 at 150 °C for 100 ppm of NO2 gas. Moreover, the bacteria were completely destroyed in the presence of as-deposited ZnO thin films.

Earth observing systems have proven to be a unique source of long-term synoptic information on numerous physical, chemical and biological parameters on a global scale. Merging this information for integrated studies that peruse key questions about the ocean-atmosphere interface is, however, very challenging. Such studies require interdisciplinary frameworks and novel insights into ways to address the problem. We present here a perspective review on how current and emerging remote sensing technologies could help address two scientific questions within the Surface Ocean-Lower Atmosphere Study (SOLAS) science plan: (1) to what extent does upper-ocean biology affect the composition and radiative properties of the marine boundary layer; and (2) to what extent does upper-ocean turbulence drive fluxes of mass and energy at the air-sea interface. We provide a thorough review of how these questions have been addressed and discuss novel potential avenues using multiplatform space-borne missions, from visible to microwave, active and passive sensors.
Chopin's Aliases
Authors: Moseley Roger
Published: November 2018

The ambiguity of Chopin's music and its amenability to reinvention help account for its enduring appeal to pianists, composers, and critics. This article examines the conditions under which such ambiguity has taken shape on the page and at the piano. Just as curves become jagged—or “aliased”—when represented by the grid of discrete pixels that form digital displays, so have the contours of Chopin's music been both veiled and disclosed by the straight lines that define the staff and the keyboard. Despite the term's contemporary ring, the issues raised and reflected by aliasing are rooted in a set of nineteenth-century dichotomies concerning the discrete and the continuous, artifice and nature, instruments and bodies, virtuosity and poetry, machines and voices, and constraints and liberties, all of which Chopin's music was heard both to invoke and to elude. By way of recordings and transcriptions by Leopold Godowsky, Marc-André Hamelin, Josef Lhévinne, Vladimir de Pachmann, Ignacy Jan Paderewski, and Arthur Rubinstein, the article presents various instances of aliasing and attempts to mitigate it via a range of compositional, pianistic, and cultural techniques that reveal how aliases can produce ambiguity by calling the very distinction between identity and difference into question.
¿Es la conciencia fenoménica una condición necesaria para la intencionalidad? Limitaciones del inseparatismo fenomenalista
Authors: Domínguez Asier Arias
Published: November 2018

Una de las principales líneas divisorias dentro del debate en torno al problema de la conciencia deja a un lado la postura del separatismo representacionalista y al otro la del inseparatismo. Según la primera, pueden existir estados mentales representacionales en ausencia de conciencia fenoménica y, además, una adecuada teoría naturalista de la representación es necesaria y suficiente para la explicación de la conciencia fenoménica. De acuerdo con la segunda, la conciencia fenoménica es necesaria para la existencia y la explicación de cualquier estado representacional y, de hecho, de cualquier estado mental. Varios argumentos han tratado de ofrecer respaldo a esta tesis inseparatista. Los propuestos por Strawson y Searle compendian la forma de esta clase de argumentos, basados en introducir intuitivamente la conclusión a la que aspiran mediante premisas implícitas. A este problema se suman la inoperancia e inadecuación empírica del inseparatismo y asimismo su falta de verosimilitud filogenética.

Medaka is a model organism in medicine, genetics, developmental biology and population genetics. Lab stocks composed of more than 100 local wild populations are available for research in these fields. Thus, medaka represents a potentially excellent bioresource for screening disease-risk- and adaptation-related genes in genome-wide association studies. Although the genetic population structure should be known before performing such an analysis, a comprehensive study on the genome-wide diversity of wild medaka populations has not been performed. Here, we performed genotyping-by-sequencing (GBS) for 81 and 12 medakas captured from a bioresource and the wild, respectively. Based on the GBS data, we evaluated the genetic population structure and estimated the demographic parameters using an approximate Bayesian computation (ABC) framework. The genome-wide data confirmed that there were substantial differences between local populations and supported our previously proposed hypothesis on medaka dispersal based on mitochondrial genome (mtDNA) data. A new finding was that a local group that was thought to be a hybrid between the northern and the southern Japanese groups was actually an origin of the northern Japanese group. Thus, this paper presents the first population-genomic study of medaka and reveals its population structure and history based on chromosomal genetic diversity.
Aprovechamiento de ñandú (Rhea americana) en la prehistoria del sudeste uruguayo
Authors: Moreno Federica
Published: November 2018

El sitio Ch2D01 es un conjunto de dos montículos y varios microrelieves ubicado en el sudeste uruguayo, cuya ocupación data del Holoceno tardío. En este trabajo se analizan los restos óseos de ñandú (Rhea americana) recuperados en uno de los montículos (excavación IA). En este conjunto zooarqueológico, el ñandú representa únicamente el 0,5% de los restos determi- nados a nivel de especie y género y el 0,1% del total. Los 20 restos identificados representan un NMI=5 y corresponden en todos los casos a elementos de los miembros posteriores (tibiotarso, tarsometatarso y falanges). A pesar de esto, constituye un caso excepcional para la región donde los restos óseos de ñandú están ausentes en la mayoría de los sitios arqueológicos. Esta situación es similar a la descrita en diversos trabajos de sitios ubicados en la Pampa y Patagonia argenti- nas: baja presencia de ñandú y sobrerepresentación de elementos de las extremidades traseras. Los resultados son discutidos teniendo en cuenta la anatomía económica del animal, su densidad mineral ósea y las propuestas realizadas para los yacimientos argentinos. La representatividad anatómica es más coherente con un sitio de consumo de carne, médula y productos no comes- tibles que con un sitio de captura o de consumo de grasa. No se encontró correlación entre los elementos recuperados y la densidad mineral ósea, aunque lo reducido de la muestra no permite descartar del todo problemas de equifinalidad
Relaciones simbólicas entre sociedades indígenas y el mundo animal en Ventania (Provincia de Buenos Aires, Argentina): el caso de los Rheidae

En este trabajo se aborda el estudio de las vinculaciones de las sociedades cazado- ras-recolectoras con los recursos faunísticos disponibles en el Sistema Serrano de Ventania y su llanura adyacente, a través de su representación en el registro arqueológico del Holoceno tardío. Además de la evidencia arqueológica, se complementan los datos obtenidos con la información procedente de las fuentes históricas y etnohistóricas sobre la subsistencia, ceremonias y rituales de los grupos pampeanos en el período de contacto hispano-indígena. El análisis realizado ha permitido considerar tanto la utilidad económica de los animales representados como el rol simbólico que cumplían en la cosmovisión indígena.
Manufacturing technique and social identity: three cases of ‘manufacture-by-wear’ technique
Authors: MĂRGĂRIT MONICA , MIREA PAVEL , BĂLĂȘESCU ADRIAN
Published: November 2018

This paper focuses on the identification of changes in the processing of osse- ous materials in the southeast European Neolithic, beginning with three types of production by manufacture wear technique typical for the region: bipartition by abrasion, segmentation with fibre and perforation by wear technique. The processing of osseous materials is strongly conditioned by their natural anatomic shapes which is why only a restricted range of possible transformation variables, with minimum changes through time, would be expected. However, numerous specialists invoke the cultural value conferred by the community as the preeminent element in the selection of raw material more than the limitations of the raw material form. Therefore, there are some examples in which there was little change in raw materials selec- tion across long periods of time, although there was variation in animal species availability. Consequently, the study of the three types of ‘manufacture-by-wear’ technique becomes more interesting. These techniques are not present in all prehistoric times in this region. Some of these techniques appear on worked osseous materials in Romania and neighbouring areas at the beginning of the Neolithic and disappear just as suddenly (bipartition by abrasion) or appear only sporadically (perforation and segmentation with fibre) by the Early Chalcolithic. Based on experimental reconstructions of the three processing techniques and comparing them with archaeological assemblages, our study aims to register all the relevant variables (technological gestures, time required for each operation, tools used etc.), and evaluate if they represented a real innovation in the way which the osseous materials were processed.

Dynamic heating computer simulations of one model typical living room heated alternatively by two types of heating bodies are presented in this paper. This contribution describes a numerical model of two heating elements (plate radiator and a new type of convector) showing different thermal inertia by using the TRNSYS software. The results show energy savings approximately of 10% for the new tested convector, where the thermal comfort is better in terms of reaching the required room temperature.

Adaptive immunity is essentially required to control acute infection with enteropathogenic Yersinia pseudotuberculosis (Yptb). We have recently demonstrated that Yptb can directly modulate naïve CD4+ T cell differentiation. However, whether fully differentiated forkhead box protein P3 (Foxp3+) regulatory T cells (Tregs), fundamental key players to maintain immune homeostasis, are targeted by Yptb remains elusive. Here, we demonstrate that within the CD4+ T cell compartment Yptb preferentially targets Tregs and injects Yersinia outer proteins (Yops) in a process that depends on the type III secretion system and invasins. Remarkably, Yop-translocation into ex vivo isolated Foxp3+ Tregs resulted in a substantial downregulation of Foxp3 expression and a decreased capacity to express the immunosuppressive cytokine interleukin-10 (IL-10). Together, these findings highlight that invasins are critically required to mediate Yptb attachment to Foxp3+ Tregs, which allows efficient Yop-translocation and finally enables the modulation of the Foxp3+ Tregs' suppressive phenotype.
Viktor Frankl: o sentido da Logoterapia e sua atualidade contextual
Authors: Andrade Cristiano De Jesus
Published: November 2018

Viktor Emil Frankl foi médico, austríaco e fundador da escola da Logoterapia, que explora o sentido existencial do indivíduo e a dimensão espiritual da existência. A autenticidade do trabalho proposto pelo autor em questão tem seu alicerce em sua experiência vivida em quatro campos de concentração nazistas. A Logoterapia parte da dimensão espiritual para abordar sua relação com as outras dimensões da vida. Estuda as situações específicas da esfera da existência do indivíduo, sem negligenciar ou negar os conflitos, sejam eles expressos por sintomas somáticos ou psicológicos. Constitui uma linha de psicoterapia centrada no sentido e que considera sua tarefa ajudar o paciente a encontrar sentido em sua vida tornando a principal força motivadora no ser humano. Quanto à origem do sentimento de falta de sentido, pode-se dizer, ainda que as pessoas tenham o suficiente com o que viver, mas não têm nada por que viver; têm os meios, mas não têm o sentido. Esse tem que ser encontrado pela própria pessoa, mas não dentro dela, porque isto iria contra a lei da auto-transcendência do existir humano. Ao tentar responder à questão do sentido da vida - a mais humana de todas as questões - o homem é remetido para si mesmo, tornando-se alguém a quem a vida interroga alguém que a esta tem de responder, sendo responsável, assim, por sua vida.
Development of a road shoulder's equivalent sound source traffic noise prediction model

Published: November 2018

The accuracy of traffic noise prediction models (TNMs) is impaired by affecting factors and system errors. In addition, the traditional traffic noise source cannot be tested as the sound source is generated in the centreline of the road. To address these limitations, a TNM based on the equivalent sound source at the road shoulder was developed. First, the equivalent traffic flow based on the acoustic-equivalent conversion coefficient was calculated and the traffic noise source intensity model was deduced. The shoulder's sound pressure level (SPL) data were then used to formulate a single-vehicle equivalent SPL model and correct the traffic noise source intensity model. The propagation model was fitted according to the attenuation law that traffic noise strength attenuates gradually from the shoulder to the road outside and fluctuates periodically. The results of a case study showed that the absolute percentage error of the proposed model's prediction was 2·3% compared with the measured value, which was better than the performance of the current model suggested in the Chinese specification. The proposed prediction model provides a friendly and less time-consuming approach for city planners and traffic engineers to conduct freeway traffic noise prediction and assessment.
