Testing Geomagnetic Reference Field models for 1990-2000 with data from the Trelew Geomagnetic Observatory, Argentina
Authors: Gianibelli Julio C. , Köhn Jacqueline , Ghidella Marta E.
Published: May 2021

En los relevamientos magnéticos realizados sobre la superficie de la Tierra se utiliza el Campo Geomagnético Internacional de Referencia (IGRF) para sustraer la contribución del campo principal de la Tierra. Cada cinco años se publica un nuevo modelo de IGRF y la variación secular del período previo debe ser actualizada, generándose el denominado modelo DGRF. Una vez que el DGRF es publicado, las anomalías magnéticas calculadas previamente deben ser recalculadas. La actualización de las anomalías podría ser particularmente importante para relevamientos magnéticos regionales o para compilaciones de datos magnéticos adquiridos en diferentes épocas. En este trabajo se muestra la importancia de esta corrección, particularmente para el periodo 1995-2000, en el cual la diferencia DGRF-IGRF es llamativamente apreciable. Se documenta la validez de la corrección utilizando datos del Observatorio Geomagnético Permanente de Trelew, Argentina.

Introducción: El Síndrome de Desgaste Laboral o Burnout, es entendido como una baja resiliencia para afrontar el estrés laboral. Objetivo: Identificar factores asociados al Burnout y la prevalencia global y de cada uno de sus constructos, entre auxiliares de enfermería en un hospital de referencia de mediana y alta complejidad, en Colombia. Materiales y métodos: Estudio de casos y controles, con 183 auxiliares registradas en un hospital. Se utilizó el instrumento de Maslach y se identificaron los factores asociados utilizando la regresión Log-Binomial determinando los Odds Ratio (OR). Resultados: Los factores encontrados asociados con Burnout que aumentan la probabilidad de ocurrencia son: trabajar más de 48 horas por semana, OR=1,02 (1,01-1.05) al 90% de confianza; sentirse mal con el trabajo que se realiza OR=3,87 (1,18-10,71); el dormir siete horas o más al día OR=0,70 (0,53-0,91), disminuye la probabilidad. La prevalencia total de Burnout fue 44,7%, siendo 11,8% para agotamiento personal, 14,9% despersonalización y 47,81% pobre realización personal. Conclusiones: Los factores asociados: no dormir suficiente y sentirse mal con la tarea que se realiza, aumentan la probabilidad de desarrollar Burnout, mientras que dormir 7 o más horas diarias la disminuye. Estos hallazgos facilitarán la aplicación de medidas de control institucional.

Published: May 2021

Introducción: El condón es un método de prevención de las Infecciones de Transmisión Sexual (ITS) y del embarazo, sin embargo, su uso en jóvenes colombianos es bajo. Objetivo: Identificar las barreras y limitaciones individuales, culturales e institucionales, en el uso del condón en jóvenes universitarios. Materiales y métodos: Investigación cualitativa, con 4 grupos focales mixtos con jóvenes de 17 a 24 años. Se realizó codificación con el software ATLAS.TI y un análisis temático. Resultados: A nivel individual se evidencia baja intención de uso, la confianza en la pareja aleja el temor de una ITS y el embarazo es la principal preocupación que desplaza su uso por otro método anticonceptivo. A nivel cultural las relaciones de género refuerzan que la mujer es responsable de los anticonceptivos y el hombre del condón. A nivel institucional, las políticas y los servicios de salud limitan su acceso. La lógica mercantilista y el enfoque de riesgo limitan la distribución gratuita y masiva. Conclusiones: El reconocimiento de factores individuales y sociales que limitan el uso del condón, permite la promoción del cuidado de sí y del otro; además la orientación de estrategias para promover una adecuada atención en los servicios de Salud Sexual y Reproductiva.
Quantum Chaos is Quantum

Published: May 2021

It is well known that a quantum circuit onNqubits composed of Clifford gates with the addition ofknon Clifford gates can be simulated on a classical computer by an algorithm scaling aspoly(N)exp⁡(k)\cite{bravyi2016improved}. We show that, for a quantum circuit to simulate quantum chaotic behavior, it is both necessary and sufficient thatk=Θ(N). This result implies the impossibility of simulating quantum chaos on a classical computer.
Qubit-efficient encoding schemes for binary optimisation problems
Authors: Tan Benjamin , Lemonde Marc-Antoine , Thanasilp Supanut , Tangpanitanon Jirawat , Angelakis Dimitris G.
Published: May 2021

We propose and analyze a set of variational quantum algorithms for solving quadratic unconstrained binary optimization problems where a problem consisting of nc classical variables can be implemented on O(log⁡nc) number of qubits. The underlying encoding scheme allows for a systematic increase in correlations among the classical variables captured by a variational quantum state by progressively increasing the number of qubits involved. We first examine the simplest limit where all correlations are neglected, i.e. when the quantum state can only describe statistically independent classical variables. We apply this minimal encoding to find approximate solutions of a general problem instance comprised of 64 classical variables using 7 qubits. Next, we show how two-body correlations between the classical variables can be incorporated in the variational quantum state and how it can improve the quality of the approximate solutions. We give an example by solving a 42-variable Max-Cut problem using only 8 qubits where we exploit the specific topology of the problem. We analyze whether these cases can be optimized efficiently given the limited resources available in state-of-the-art quantum platforms. Lastly, we present the general framework for extending the expressibility of the probability distribution to any multi-body correlations.

Aim: The present study was carried out with an aim to select promising individual oil palms from Nigerian source population at Hut Bay, Little Andaman Island for utilization in breeding programme, enrich germplasm assemblage and conservation in the field gene bank. Methodology: The Nigerian source oil palm were subjected to fruit cut testing and evaluated for eleven bunch quality components of horticultural importance at Oil Palm Research Centre, Palode in Kerala. Results: The maximum standard deviation was observed for total number of fruits followed by total number of spikelet and percentage of shell/fruit, whereas highest CV % was recorded for bunch weight followed by oil to bunch %, single fruit weight and single nut weight. The four identified palms had maximum values of bunch components viz, total number of spikelet, single fruit weight, total number of fruits, mesocarp tofruit and oil to bunch with 262, 15.79g, 2246, 73.79 % and 37.3 %, respectively. Principal Component Analysis of bunch components revealed that the first three principal components accounted for 79.1% of the variability observed with Eigen value more than one. The most important bunch components that contributed more to the diversity of the oil palms are fruit to bunch, single nut weight, single kernel weight, bunch weight, total number of spikelets, total number of fruits and shell thickness. Interpretation: The significant genetic diversity observed among the individual palms of Nigerian source suggests that these palms are best donors of new genes for oil palm improvement as well as widening the genetic base.

Aim: The study was conducted to explore the magnitude of variability induced by gamma rays, electron beam and its combinations for quantitative traits in horsegram (Macrotyloma uniflorum (Lam) Verdc.). Methodology: The horsegram cultivar PAIYUR 2 was irradiated with twelve combinations involving G, EB and G+EB. Desirable mutagenic doses were identified in M1 based on plant injuries and forwarded to M2. Data on 11 yield component traits were recorded on normal looking M2 plants for identification of micro-mutants. Promising mutants were forwarded to M3 and the induced variability was ascertained using multivariate statistics. Results: Significant transgressive variants were observed in M2. The G+EB combination induced superior variants for yield. A positive shift in mean for yield and its attributing traits was observed in M3. Most of the polygenic traits were governed by additive gene effects. Interpretation: The increased mean for most of the polygenic traits in M3 population proved that selection made on early generation was highly effective. The isolated high yielding mutant progenies of selected families will contribute towards yield improvement in horsegram.

Aim: To study the carbon sequestration process in tea based plantation system and to identify more potential carbon sequestration system amongst the tea based cropping system by studying carbon storage in different components of the plantation system. Methodology: The experiment was carried out in the Experimental Garden for Plantation Crops of Assam Agricultural University, Jorhat, Assam. Treatments were made in an on going, long term shade experiment on mature tea bushes, adapted to three levels of shades viz. tea as monoculture; Tea based cropping system with Areca palm and Tea with Albizzia odoratissima. Results: Among different tea plantations, tea-albizzia recorded superior performance, followed by tea-areca palm plantation in respect to biomass accumulation and carbon sequestration. Similarly, higher carbon stock was found in tea-albizzia plantations along with other physiological and edaphic parameters related to carbon sequestration attributed to an increase in carbon stock. Interpretation: Tea-albizzia plantation system has maximum potential for carbon offsetting from the atmosphere as well as carbon storage both above and below ground in the plantation ecosystem which might be helpful for future carbon management and economy as a whole.

Aim: To study the relative incidence of mustard aphid and Alternaria blight on different rapeseed-mustard varieties to assess their resistant or tolerant and most suitable variety for sub-mountainous area of Punjab. Methodology: The experiment was conducted on four mustard varieties (RLM-619, PBR-97, PBR-357 and Giriraj) with five replications in randomized block design during two crop seasons, i.e. Rabi 2018-19 and 2019-20 under sub-mountainous areas of Punjab. Aphid population was recorded at weekly interval. Disease severity was calculated using 0-5 rating scale and per cent disease intensity was calculated. Results: RLM-619 variety exhibited the lowest aphid infestation (7.92 and 8.96%) and minimum per cent disease intensity (28.0 and 33.33%) on leaves and siliqua (33.33 and 38.33%) which also gave highest yield (739.33 kg acre-1 and 735.67 kg acre-1) during the year 2018-19 and 2019-20. The lowest seed yield (487.67 kg acre-1 and 480.67 kg acre-1) was recorded in variety Giriraj, which was found susceptible to aphid infestation and Alternaria blight. Interpretation: RLM-619 exhibited tolerance against aphid and Alternaria blight, hence, this variety may be used as a key component under integrated pest and disease management in sub-mountainous area of Punjab in future.

im: The dispersal and geographical range expansion of globally invasive snail Physella acuta (Draparnaud, 1805) (Gastropoda: Physidae) were little being monitored following the first report from Kolkata, India. An account of the encounter of P. acuta in two ponds of North Dinajpur district of West Bengal, India is recorded here. Methodology: Multiple samples of freshwater snails were collected using aquatic nets from the invaded and non-invaded ponds for assessment and comparison. The shell lengths of the collected P. acuta were measured using a vernier calliper to represent size class variations of the population in the ponds. Results: Varying numbers of P. acuta were present in the shoreline and the hydrophytes of littoral zone of invaded ponds. The size class distribution of P. acuta indicated the establishment of a stable population in the invaded ponds where a significant difference (P < 0.05) was observed in the abundance of a native snail Racesina luteola (Lamarck, 1822) when compared with the abundance in the non-invaded ponds. Interpretation: Invasion of P. acuta in the ponds reflected its ability to overcome the predator-borne barriers and to coexist with the native snails. The geographic range of P. acuta seems to have extended, even though slower with reference to the first record in India.

Jazz in Worship and Worship in Jazz
The musical language of Liturgical, Sacred, and Spiritual Jazz in a postsecular Age.

Abstract

The aim of this dissertation is to identify musical elements that contribute to the generation of religious meaning in jazz performance and to explore how religious experience can inspire jazz composition.

In this study, the history of jazz, specifically tailored to the aspects of my inquiry is imbricated with relevant theories and musical interventions from my own artistic practice in composition and performance. In addition to artistic research through my own practice as a performer and composer, the transdisciplinary fields of musicology, music theory, neurology, history of religion, and theology provides further critical tiles in the knowledge-mosaic constructed by this study.

Using my own artistic practice as my primary research method, my thesis investigates distinct intrinsic and extra-musical elements that help to create a typology of religiously inspired jazz, grounded in historical reference works. Twenty-five of my own compositions following this typology are submitted with this thesis and are analyzed in the three main chapters.

The final chapter (Imagine) summarizes conclusions of the main chapters and includes a brief evaluation of the research process. Conclusions from the thesis include (i) defining six distinct ways of expressing religious belief in jazz, (ii) demonstrating that the extrinsic meaning of religiously inspired jazz changes when placed within a liturgical dramaturgy, and (iii) generating new postsecular perspectives on jazz. Another concrete result of this thesis involves revisiting George Russell´s Lydian Chromatic Concept as a basis for my own compositions. The practice-based adaption and exploration of Russell´s theory opens new ways of understanding how his musical philosophy builds a bridge between Western classical sacred music and jazz. Finally, this thesis also raises new areas for further research such as microtonal and twelve-tone tonality in jazz, temporal concepts in jazz composition and improvisation, and the embodiment of Christian faith through music as an extension of the institutional church in society.

Keywords: jazz and religion, jazz liturgies, George Russell, Spiritual Jazz, Sacred Jazz, Liturgical Jazz, postsecularity in the arts, twelve-tone tonality in jazz

GH57GBEs have been biochemically characterized so far. This study aimed
at acquiring a better understanding of the GH57GBE family by a
systematic sequence-based bioinformatics analysis of almost 2,500 gene
sequences and determining the branching activity of several native and
mutant GH57GBEs. A correlation was found between a very low or even no
branching activity with the absence of a flexible loop, a tyrosine at
the loop tip, and two β-sheets.

We report here an assessment of the model refinement category of the
14th round of Critical Assessment of Structure Prediction (CASP14). As
before, predictors submitted up to five ranked refinements, along with
associated residue-level error estimates, for targets that had a wide
range of starting quality. The ability of groups to accurately rank
their submissions and to predict coordinate error varied widely. Overall
only four groups out-performed a “naïve predictor” corresponding to
resubmission of the starting model. Among the top groups there are
interesting differences of approach and in the spread of improvements
seen: some methods are more conservative, others more adventurous. Some
targets were “double-barrelled” for which predictors were offered a
high-quality AlphaFold 2 (AF2)-derived prediction alongside another of
lower quality. The AF2-derived models were largely unimprovable, their
apparent errors being found to reside very largely at domain and,
especially, crystal lattice contacts. Refinement is shown to have a
mixed impact overall on structure-based function annotation methods to
predict nucleic acid binding, spot catalytic sites and dock protein
structures.
Assessing the Relevance of County-Level Eco-Efficiency to Single-Family Housing Prices

Published: May 2021

Eco-efficiency has been used in the private sector to measure how resources are used to produce environmental outcomes. In these instances, eco-efficiency has a reported signaling effect that increases value for stakeholders. Public sector research suggests increased spending on social goods at the national (country) level results in reduced emissions with the resulting effect of an improved environment. This study extends previous research by applying eco-efficiency to the public sector in a significantly different public entity, county government, and by linking spending on social goods (input) and emissions (output) to a direct outcome of measurable economic value to citizenry, single-family housing prices, for 66 Florida counties during the years 2005–2014. Results show a positive and significant relationship between eco-efficiency and single-family housing prices. These results suggest county-level eco-efficiency may be an important element to include in external reports to citizens.

OBJECTIVE

Epidemiological studies have shown contradictory results regarding the time trend of end-stage renal disease (ESRD) in people with diabetes. This study aims to analyze the incidence of ESRD, defined as chronic renal replacement therapy (RRT), to investigate time trends among people with and without diabetes in Germany and to examine whether these patterns differ by age and sex.

RESEARCH DESIGN AND METHODS

The data were sourced from nationwide data pooled from two German branches of statutory health insurances covering ∼25 million inhabitants. We estimated age- and sex-standardized incidence rates (IRs) for chronic RRT among people with and without diabetes in 2010–2016 and the corresponding relative risks. Time trends were analyzed using Poisson regression.

RESULTS

We identified 73,638 people with a first chronic RRT (male 60.0%, diabetes 60.6%, mean age 71.3 years). The IR of chronic RRT among people with diabetes (114.1 per 100,000 person-years [95% CI 110.0–117.2]) was almost six times higher than among people without diabetes (19.6 [19.4–19.8]). A consistent decline in IR was observed among people with diabetes (3% annual reduction, P < 0.0001) for both sexes and all age classes. In contrast, no consistent change of IR was identified in people without diabetes. Only among women aged <40 years (P = 0.0003) and people aged ≥80 years (P < 0.0001) did this IR decrease significantly.

CONCLUSIONS

Incidence of chronic RRT remained significantly higher among people with diabetes. The IR decreased significantly in people with diabetes independent of age and sex. Time trends were inconsistent in people without diabetes.

replacement therapy (RRT), to investigate time trends among people with and
without diabetes in Germany and to examine if these patterns differed by age
and sex.

Research design and methods The data was sourced from nationwide data pooled from

(IR) for chronic RRT among people with and without diabetes in 2010–2016, and
the corresponding relative risks. Time trends were analysed using Poisson
regression.

Results We identified 73,638 people with a first chronic RRT (male: 60.0%, diabetes:
60.6%, mean age: 71.3 years). The IR of chronic RRT among people with diabetes

A consistent decline in IR was
observed among people with diabetes (3% annual reduction, p < 0.0001) in
both sexes and all age classes. In contrast, no consistent change of IR was
identified in people without diabetes. Only among women aged under 40 (p=0.0003)
and people aged 80 and over (p<0.0001) this IR decreased significantly.

Conclusion Incidence of chronic RRT remained significantly higher
among people with diabetes. The IR decreased significantly in people with
diabetes independent of age and sex. Time trends were inconsistent in people
without diabetes.

La sostenibilidad de agroindustrias convencionales se enfoca hacia la transición en biorrefinerías. El objetivo de este trabajo fue evaluar estrategias para obtener biocombustible sólido, abonos de los subproductos de las agroindustrias de naranja de jugo y caña de azúcar en Veracruz, México y la zonificación agroecológica para determinar la expansión de estos cultivos de manera sostenible para futuras biorrefinerías integrales. El método de biosecado empleó cáscaras de naranja, bagazo de caña y residuos de cosecha obteniendo un biocombustible sólido al reducir la humedad inicial de 87,72% a 12,28 % en un periodo de 30 días. Se evaluaron seis tratamientos de producción de abono en contenedores plásticos de 30 a 90 días utilizando subproductos: cáscara de naranja, cachaza, vinazas, melazas, cenizas, estiércoles, residuos de cosecha cañera y de producción de hongos comestibles mediante las técnicas de compostaje, vermicompostaje y bocashi. Se obtuvieron abonos con pH de 5,4 a 12, M.O. de 3 a 70 % y relación C/N de 8 a 40. La zonificación agroecológica se realizó con el software Maxent. Se determinó que las regiones geográficas con mayor aptitud para cultivos de cítricos y caña de azúcar se localizan en el sureste mexicano y en particular el estado de Veracruz. Para caña de azúcar, los factores limitantes a la productividad como materia prima para biorrefinerías, están relacionados con el acceso al agua (precipitación pluvial) y explican el 57,1 % de la simulación. En el caso de cítricos, los factores se relacionan con temperatura, precipitación pluvial y topografía, que en su conjunto impactan el 44,5 %.

La semilla de mango es un residuo de las empresas productoras de concentrados y jugos, ella generalmente es desechada en rellenossanitarios o es utilizada en alimentación de animales como consumo directo. La semilla de mango tiene dos partes principales, el cotiledóny el endocarpio, en el caso del cotiledón, puede ser aprovechado en la industria de alimentos y cosmética; es así como el objetivo del presentetrabajo consiste en aprovechar la harina de cotiledón de mango en la formulación de un producto alimenticio elaborado en el Centropara la Formación Cafetera del SENA regional Caldas. El procedimiento de preparación de la semilla fue: Lavado de semillas, secado,separación de endocarpio a través de guillotina, molienda y secado a temperatura controlada, posteriormente empacado y conservación enrefrigeración. Se evaluó la separación del aceite y la harina mediante métodos de extracción como compresión por tornillo sin fin y métodoSoxhlet. Para el diseño del prototipo alimenticio se determinaron los porcentajes de materias primas que formarían la masa galletera. Luego,se horneó la masa y se procedió a realizar análisis sensoriales y bromatológicos de alimentos, de acuerdo a parámetros de normativa legal vigente, encontrando que las masas trabajadas con harinas de cotiledón de mango presentan mayor retención de humedad, texturas arenosas y notas achocolatadas en el producto final; estas masas no forman gel, no incrementan su viscosidad y poseen menor cantidad de humedad, así como menor aw, dando como resultado una mayor estimación de vida útil; con lo cual las harinas de cotiledón de mango pueden contribuir con el incremento de la vida de anaquel de productos de galletería, al disminuir la cantidad de agua libre, presente en este tipo de alimentos.
DE ORIENTES E ÁFRICAS: VISUALIDADES COLONIAIS NAS IMAGENS DOS CARTÕES-POSTAIS DA COLEÇÃO AUGUSTO OLIVEIRA
Authors: Barbosa Cibele
Published: May 2021

Entre os anos de 1906 e 1908, o cartofilista Augusto de Oliveira recebeu mais de 300 cartões-postais de diversas partes do mundo. Do Cairo a Tóquio, esses postais, ilustrados com fotografias de “tipos” e “paisagens”, são registros de uma época imersa em um regime de visualidade marcado pela reprodutibilidade técnica da imagem e pelo colonialismo europeu na África e Ásia. Com base em estudos contemporâneos da Cultura Visual e em leituras pós-coloniais, a pesquisa sobre esse farto material iconográfico abre novas janelas analíticas para pensar de que modo o culto ao exótico e a episteme racializada da época informaram percepções e produziram olhares transnacionais sobre o “Outro”.
