Authors: CAMPOS RIOS MAXIMILIANO ULISES , SACOMANI MARÍA DEL ROSARIO 
Published: January 2021

El presente trabajo intenta estructurar los principales problemas teóricos y prácticos del Estado y las políticas públicas para el manejo de la emergencia y la gestión de la pandemia del COVID-19 durante el 2020. Estos son: 1) la capacidad estatal; 2) la gestión de la emergencia; 3) la movilización de recursos; 4) los problemas de articulación interna; 5) la coordinación multinivel; 6) los desafíos de la comunicación; 7) el uso de evidencia y la gestión de la incertidumbre; 8) la construcción de protocolos; 9) la gobernanza y liderazgo del proceso; y 10) el cumplimiento normativo (compliance) público durante la emergencia. En ese sentido, los desafíos de la «nueva normalidad» implican, por un lado, incorporar las lecciones aprendidas de la gestión de la emergencia, y por el otro, hacer un ejercicio prospectivo que ponga en crisis al modelo desde el momento de su implantación y que potencie los aspectos adaptativos del mismo en el marco de una realidad contingente y desafiante.
Lan honek 2020an larrialdia kudeatzeko eta COVID-19aren pandemia kudeatzeko Estatuaren eta politika publikoen arazo teoriko eta praktiko nagusiak egituratu nahi ditu. Hauek dira: 1) estatuaren gaitasuna; 2) larrialdiaren kudeaketa; 3) baliabideen mobilizazioa; 4) barne-artikulazioak eragindako arazoak; 5) maila anitzeko koordinazioa; 6) komunikazioaren erronkak; 7) ebidentziaren erabilera eta ziurgabetasunaren kudeaketa; 8) protokoloen eraikuntza; 9) prozesuaren gobernantza eta lidergoa; eta 10) larrialdian zehar compliance publikoa. Ildo horretan, «normaltasun berriaren» erronkek eskatzen dute, alde batetik, larrialdiaren kudeaketatik ikasitako irakaspenak txertatzea, eta, bestetik, ezartzen den unetik bertatik eredua krisian jarriko duen ariketa prospektibo bat egitea, eredua egokitzeko alderdiak indartzeko, errealitate kontingente eta desafiatzaile baten esparruan.
This paper attempts to structure the main theoretical and practical problems of the State and public policies for emergency management and the administration of the Covid19 pandemic during 2020. These are: 1) State capacity; 2) Emergency management; 3) Mobilization of resources; 4) Internal articulation problems; 5) Multilevel coordination; 6) Communication challenges; 7) The use of evidence and the management of uncertainty; 8) Construction of protocols; 9) Governance and leadership of the process; and 10) Public compliance during the emergency. In this sense, the challenges of the «new normal» imply, on the one hand, incorporating the lessons learned from emergency management, and on the other, carrying out a prospective exercise that puts the model in crisis from the moment of its implementation., empowering the adaptive aspects of it in the framework of a contingent and challenging reality.

Objetivo: interpretar la percepción de bienestar psicológico que poseen las personas mayores de una comuna de la Región del Bío-Bío, Chile.
Métodos: se utilizó el paradigma cualitativo con enfoque fenomenológico. El muestreo fue no probabilístico por conveniencia a través de saturación teórica. Los participantes que se incluyeron cumplieron con los criterios de selección y firma de consentimiento informado. La recolección de información se realizó a través de una entrevista semiestructurada que basó sus preguntas en el Modelo Multidimensional de Bienestar. Los resultados fueron codificados y analizados mediante análisis de contenido.
Resultados: Las personas mayores investigadas poseen un alto nivel de bienestar psicológico. La principal fuente de bienestar psicológico es de tipo relacional, la familia y su entorno más cercano. La evaluación que realiza la persona mayor, en el presente, involucra las condiciones en las cuales se desenvuelve y las formas en las cuales enfrentaron situaciones de exigencia emocional durante la vida.
Conclusiones: Se identifica un alto nivel de bienestar psicológico en la población estudiada.
Desigualdades étnicas y de género en la prevalencia de presión arterial elevada en población general de Cochabamba: un análisis interseccional de inequidades en salud
Authors: Mamani Ortiz Yercin , Luizaga Lopez Jenny Marcela , Illanes Velarde Daniel Elving 
Published: January 2021

Las desigualdades en salud comúnmente son evaluadas en una sola dimensión de análisis y poco se conoce sobre el efecto sumativo o multiplicativo cuando se combinan 2 o más dimensiones sociales; representando un desafío para la prevención y control de la Presión Arterial Elevada (PAE).
Objetivo: analizar los factores involucrados en las desigualdades poblacionales de la prevalencia de PAE en el espacio inter seccional de los procesos de ventaja y desventaja social por referencia étnica y de género.
Métodos: estudio observacional, de corte transversal con enfoque interseccional. Participaron sujetos mayores de 18 años con residencia permanente en Cochabamba (n=10595), seleccionados mediante muestreo aleatorio trietápico. Se utilizó la encuesta WHO-STEPS para recopilar información sobre PAE y factores de riesgo asociados. Se construyeron cuatro posiciones interseccionales por la combinación de género y etnicidad. La descomposición de Oaxaca-Blinder se aplicó para estimar las contribuciones de los factores explicativos de las desigualdades.
Resultados: la prevalencia de PAE fue mayor en los hombres-mestizos (10,76%); la disparidad por referencia de género fue más importante entre mestizos (3,74%) e indígenas (3,11%); la disparidad interseccional entre grupos extremos (3,53%) fue mayor a la disparidad entre grupos medios (3,32%). La edad, el tipo de trabajo y estilos de vida, contribuyeron más para explicar estas diferencias.
Conclusiones: la PAE no se distribuye según los patrones esperados de desventaja social en el espacio interseccional de etnicidad y género. Una alta ventaja social se relacionó con prevalencias más altas de PAE, así como los factores de riesgo de comportamiento asociados.

Motion Planning Algorithm for a Mobile Robot with a Smart Machine Vision System
Authors: Martyshkin Alexey I. 
Published: January 2021

This study is devoted to the challenges of motion planning for mobile robots with smart machine vision systems. Motion planning for mobile robots in the environment with obstacles is a problem to deal with when creating robots suitable for operation in real-world conditions. The solutions found today are predominantly private, and are highly specialized, which prevents judging of how successful they are in solving the problem of effective motion planning. Solutions with a narrow application field already exist and are being already developed for a long time, however, no major breakthrough has been observed yet. Only a systematic improvement in the characteristics of such systems can be noted. The purpose of this study: develop and investigate a motion planning algorithm for a mobile robot with a smart machine vision system. The research subject for this article is a motion planning algorithm for a mobile robot with a smart machine vision system. This study provides a review of domestic and foreign mobile robots that solve the motion planning problem in a known environment with unknown obstacles. The following navigation methods are considered for mobile robots: local, global, individual. In the course of work and research, a mobile robot prototype has been built, capable of recognizing obstacles of regular geometric shapes, as well as plan and correct the movement path. Environment objects are identified and classified as obstacles by means of digital image processing methods and algorithms. Distance to the obstacle and relative angle are calculated by photogrammetry methods, image quality is improved by linear contrast enhancement and optimal linear filtering using the Wiener-Hopf equation. Virtual tools, related to mobile robot motion algorithm testing, have been reviewed, which led us to selecting Webots software package for prototype testing. Testing results allowed us to make the following conclusions. The mobile robot has successfully identified the obstacle, planned a path in accordance with the obstacle avoidance algorithm, and continued moving to the destination. Conclusions have been drawn regarding the concluded research.

The response of active ingredient, chlorophyll a and b contents, and chlorophyll index of henna to different rates of N fertilization and drought stress was explored in a split-split-plot experiment based on a randomized complete block design with four replications in the research farm of Jiroft Branch, Islamic Azad University, Jiroft, Iran in the 2016-2017 growing season. In the current study, the main plot was assigned to drought stress at three levels (including irrigation to supply 100%, 75% or 50% of plant water requirement), the sub-plot was assigned to N fertilization at three rates (50, 100 or 150 kg ha-1 pure N), and the sub-sub-plot was assigned to ecotype at three levels (Bami, Bushehri, and Rudbari). The results showed that the effect of drought level was significant on active ingredient and chlorophyll index at the p < 0.01 level and on chlorophyll a, total chlorophyll, and chlorophyll a/b ratio at the p < 0.05 level. But, it could not influence chlorophyll b significantly. The effect of N fertilization was significant on most studied traits at the p< 0.01 level, but its effect was significant on the chlorophyll index at the p < 0.05 level and insignificant on dye and chlorophyll b. According to the results, it seems that the application of 100 kg ha-1 N and the irrigation to supply 75% of plant water requirement can contribute to having more fresh plants with the higher active ingredient and dye contents.

Published: January 2021

Introdução: As Organizações Baseadas em Projetos (OBPs) possuem como principal característica a flexibilidade de atuação no mercado. Embora positiva, tal flexibilidade resulta em barreiras ligadas a questões intrínsecas dos projetos como a temporalidade, singularidade e seu grau de independência, dificultando a Gestão do Conhecimento (GC). Este artigo tem como objetivo analisar a influência das barreiras para a GC no ambiente das OBPs. Método: Utilizando-se de uma abordagem qualitativa, foi realizado um estudo de casos múltiplos compreendendo três Empresas de Engenharia de Projetos Industriais (EEPIs), as quais se enquadram como OBPs. Os dados foram coletados por meio de entrevistas, observação direta e documentos. Resultados: Quatro das seis barreiras descritas na literatura foram confirmadas, sendo estas a temporalidade, a pouca dedicação à GC, uso de equipes temporárias e o grau de independência dos projetos. Barreiras como a terceirização, o trabalho a distância e os custos de dedicação à GC foram incluídas. Constatou-se também que a falta de rotinas não faz parte do ambiente das EEPIs e que a singularidade dos projetos não é uma barreira e sim uma oportunidade de gerar conhecimento. Conclusão: A Gestão do Conhecimento em OBPs está sujeita a particularidades que dificultam sua disseminação, conservação e uso. A análise das barreiras que dificultam a GC nestes ambientes possibilitou não somente a verificação desta influência em seus processos, como a forma e extensão com que as barreiras para GC se manifestam.

Abstract
The detrital zircons in tills overlying the Guichon Creek batholith, British Columbia, Canada, have trace element concentrations and ages similar to those of zircons from the bedrock samples from which they are interpreted to have been sourced. Rocks from the core of the batholith that host porphyry copper mineralization have distinct zircon compositions relative to the distal, barren margin. We analyzed 296 zircons separated from 12 subglacial till samples to obtain U-Pb ages and trace element compositions. Laser ablation U-Pb ages of the detrital zircons overlap within error with chemical abrasion-thermal ionization mass spectrometry U-Pb ages of the Late Triassic Guichon Creek batholith and confirm that the detrital zircons are likely derived from the batholith. The youngest intrusions of the batholith produced the Highland Valley Copper porphyry deposits and contain distinctive zircons with elevated Eu/EuN* &gt;0.4 attributed to high magmatic water contents and oxidation states, indicating higher porphyry copper potential. Zircon from till samples adjacent to and 9 km down-ice from the mineralized centers have mean Eu/EuN* &gt;0.4, which are indicative of potential porphyry copper mineralization. Detrital zircon grains from more distal up- and down-ice locations (10–15 km) have zircon Eu/EuN* mean values of 0.26 to 0.37, reflecting background values. We conclude that detrital zircon compositions in glacial sediments transported several kilometers can be used to establish the regional potential for porphyry copper mineralization.
Exhumation and Preservation of Paleozoic Porphyry Cu Deposits: Insights from the Yandong Deposit, Southern Central Asian Orogenic Belt

Published: January 2021

AbstractPaleozoic porphyry copper deposits are generally much less common than their Mesozoic or Cenozoic counterparts, as they can be completely eroded in rapidly uplifting arcs. There are, however, some large Paleozoic porphyry copper deposits preserved worldwide, especially in the Central Asian orogenic belt, although the processes by which these ancient porphyry deposits were preserved are poorly constrained. The Carboniferous Yandong porphyry copper deposit was selected as a case study to resolve this issue using a combination of thermal history models derived from low-temperature thermochronology data and regional geologic records. Our results show that Yandong preserves a record of at least two episodes of cooling separated by a phase of mild Middle Jurassic reheating. These two cooling events included one major event, linked to the Qiangtang collision or northward motion of Tarim plate during the late Permian to Triassic, and one minor event, possibly related to the Lhasa collision or closure of Mongol-Okhotsk Ocean from the Middle Jurassic to Early Cretaceous, respectively. Tectonic quiescence and limited exhumation prevailed from the Late Cretaceous to Cenozoic in the Yandong area. Combining our results with regional geologic records, we propose that extensional tectonic subsidence, postmineralization burial, dry paleoclimatic conditions, and Cenozoic tectonic quiescence were key factors for the preservation of Yandong. This study demonstrates that anomalously old apatite fission track ages, integrated with age-elevation relationships, can have implications for mineral exploration strategies in the Chinese Tianshan orogens.
Crustal-Scale Geology and Fault Geometry Along the Gold-Endowed Matheson Transect of the Abitibi Greenstone Belt

AbstractGold in the Abitibi greenstone belt in the Superior craton, the most prolific gold-producing greenstone terrane in the world, comes largely from complex orogenic mineralizing systems related to deep crustal deformation zones. In order to get a better understanding of these systems, we therefore combined new magnetic, gravity, seismic, and magnetotelluric data with stratigraphic and structural observations along a transect in the Matheson area of the Abitibi greenstone belt to constrain large-scale geologic models of the Archean crust. A high-resolution seismic transect reveals that the well-known Porcupine Destor fault dips shallowly to the south, whereas the Pipestone fault dips steeply to the north. Facing directions and gravity models indicate that these faults are thrust faults where older mafic volcanic rocks overlie a younger sedimentary basin. The depth of the basin reaches ~2 to 2.5 km between these two faults, where it is interpreted to overlie mafic-dominated volcanic substrata. Regional seismic and magnetotelluric surveys image the full crust down to 36-km depth to reveal a heterogeneous architecture. Three crustal-scale layers include a resistive (104–105 Ωm) upper crust of granite-greenstone rocks, a low-resistivity (~10–50 Ωm) middle crust dominated by granitic plutons for which low resistivity is attributed to the presence of graphite, and a low to moderately resistive (50–1,000 Ωm) and seismically homogeneous lower crust interpreted as granulite gneisses. The significant resistivity transition between upper and middle crust is interpreted to be the result of interconnected micrographite grain coating, precipitated from carbon-bearing crustal fluids emplaced during Neoarchean craton stabilization. A major subvertical, seismically transparent, and extremely low resistive (&lt;10 Ωm) corridor connects the lower and middle crust with the upper crust. The geometry of this low-resistivity feature supports its interpretation as a deep-rooted extensional fault system where the corridor acted as a regional-scale conduit for gold-bearing hydrothermal fluids from a ductile source region in the lower crust to the depositional site in the brittle upper crust. We propose that this newly discovered whole crustal corridor focused the hydrothermal fluids into the Porcupine Destor fault in the Matheson region.

Published: January 2021

The main aim of the research was to carry out the surface modification of basalt fabric in order to improve selected thermal properties of the material, i.e., resistance to contact and radiant heat, to apply it in a hot work environment. Attention was focused on checking whether the metal coating deposited does not cause too high conductivity, which is dangerous to human health. The process of magnetron sputtering with the use of chromium and aluminum of various thickness values was applied to basalt fabrics. Based on scanning electron microscope analysis, it was found that none of the aluminum or chromium coatings covered 100% of the basalt fabric surface. Results of the surface resistance analysis of four out of the six samples of basalt fabrics tested indicate that they belong to anti-static materials. The metallic coatings obtained can potentially be used to improve the thermal properties of basalt fabric mentioned.
New Design of a Boost Drive Circuit with an Energy Recovery Function for the Piezoelectric Jacquard Needle

Published: January 2021

Aiming at the technical bottlenecks existing in the current warp knitting machine control system such as jacquard drive circuit, the design method of self-boosting power supply circuit integrated with jacquard driver is proposed for the embedded warp knitting machine jacquard control system for miniaturization design. The voltage boost circuit designed can boost the low voltage from the input of the working power supply to the high voltage for the output to drive the oscillation of the piezoelectric ceramic jacquard needles. Since the circuit adopts energy storage inductance instead of current-limiting resistor to optimize the driving circuit, it not only limits the forward charging current of the piezoelectric ceramic, but also effectively realize the energy recovery function. The effectiveness of the design method is verified by simulation.
Madonna/Mother/Death and Child: Laura Muntz and the Representation of Maternity
Authors: Mulley Elizabeth 
Published: January 2021

Vers la fin du dix-neuvième siècle, l’artiste torontoise Laura Muntz (1860–1930) était reconnue comme la peintre la plus importante du thème des mères et enfants du Canada anglais. Elle avait exposé à maintes reprises à Toronto et à Montréal et participé à de nombreuses expositions internationales (France, Angleterre et États-Unis). En 1898, après dix ans d’étude et de travail en Europe où elle avait acquis une connaissance solide des mouvements artistiques européens contemporains, elle revint à Toronto. Son arrivée coïncidait avec l’apogée du culte de la maternité au Canada. La glorification de la mère était étroitement associée à la notion de la Femme Nouvelle et au féminisme maternel conservateur et bourgeois qui préconisaient que les qualités humanitaires et nourricières innées des femmes justifiaient leur participation à la vie publique. Cet article traite de l’oeuvre Madonna and Child de Muntz et la met en relation avec les débats contemporains qui contribuèrent à la conceptualisation de la maternité. Il analyse le tableau dans le contexte des théories sur l’hérédité, du féminisme maternel et du mouvement canadien de pureté sociale, tout en considérant les implications psychologiques plus générales de l’identité féminine et plus spécifiquement les liens fin-de-siècle entre la féminité et la mort. Je propose qu’en dépit de son titre, ce tableau peu connu ne se limite ni aux thèmes chrétiens ni aux thèmes maternels, mais, au contraire, que l’image d’inspiration symboliste de Muntz peut être considérée comme un symptôme de l’ambiguïté et de la contradiction qui caractérisaient la fin de siècle et que l’oeuvre serait plus justement intitulée ainsi : Madonna/Mother/Death and Child.
