Pandemia y colaboración artística: procesos remotos y (des)conectividad en la creación digital
Authors: Da Rocha Montanari Matheus , Prado Gilbertto
Published: July 2022

Entre 2019 y 2022, el escenario de la pandemia y las medidas de confinamiento han cambiado profundamente la dinámica de la sociabilidad global. En el ámbito del arte no fue diferente, con el cierre de sus principales espacios de circulación, como estudios, museos, galerías y universidades. A partir de ahí, surgieron diferentes estrategias para posibilitar y estimular tanto la producción como la exhibición de obras, especialmente en el ámbito digital y mediante procesos a distancia. Así, presentaremos cuatro casos de estudio de situaciones de creación artística a distancia, siendo ellos: el proyecto Janelas Desobedientes (2020), Quarantine Residency(2020-2021), el museo virtual Guaraní y Kaiowá (2021-2022), y los encuentros del grupo Poéticas Digitais (2022). A partir de ellos, evaluaremos las estrategias de colaboración utilizadas, destacando sus características, señalando también cómo estas estrategias pueden haber influido o dirigido el proceso de creación. Además, abordaremos las diversidades y desigualdades que se pusieron de manifiesto en estos escenarios, haciendo, finalmente, un balance crítico entre la conexión y la desconexión.
Prácticas artísticas co-elaborativas en red: narrativas multimediales y pedagogías críticas
Authors: Fracasso Liliana , Amaral Lilian , Umpiérrez Marcos
Published: July 2022

En el marco de PANORAMA 2021, se celebró el VIII Simposio Internacional de Innovación en Medios Interactivos SIIMI 2021 | MediaLab BR,  el #20ART / UnB BR y Balance Unbalance /Canadá donde se generó una coyuntura de intercambio interinstitucional, de investigación teórica y experimentación artística, determinados por la pandemia de Covid19. La activación del OpenLab Panoramas 2021, concebido como un  espacio articulador, impulsó una serie de encuentros con artistas profesionales, investigadores y estudiantes: un laboratorio co-creativo en red. Fue el caso de la performance INLETS, que implicó temas de alcance global y creación colaborativa glocal. Asimismo repercutió en inesperados caminos autónomos de investigación-creación desarrollados localmente. A modo de caso de estudio, se presenta una experiencia desarrollada por la Accademia de Bellas Artes de Venecia, que como parte integrante de la actividad didáctica docente, articuló el Laboratorio de diseño del multimedia a los temas y la propuesta del OpenLab Agua, bajo una perspectiva inter y transcultural, enraizada en el uso de las tecnologías digitales y estimulada por la oportunidad de exploración de un espacio físico circular para proyecciones inmersivas. Las obras digitales fueron desarrolladas en red y se expusieron en Panorama Expo 2021. De la coyuntura excepcional del evento, emerge una experiencia vivenciada en un espacio liminar. Los  aportes artísticos merecen por esto una re-lectura que alimente, por una parte, el ecosistema creativo ya propiciado por el OpenLab, como modo de cocreación performativa en red, por otra, una reflexión crítica acerca de la formación académica implicada en las nuevas tecnologías, la práctica artística y los espacios fronterizos que emergen desde la cultura global contemporànea. Por tanto, el espacio virtual y el geográfico, convergen en prácticas artísticas deslocalizadas, localizadas y participativas, aportan a la experimentación de enseñanza-aprendizaje, que se alimenta de las inteligencias conectivas, colectivas y cuestiona las narrativas emergentes.
Pintura en la doblez: De la Cruz y el pliegue antropométrico.
Authors: Fernández López Carlos
Published: July 2022

Esta propuesta trata de explorar y entender el presente de los recursos y mecanismos de formalización pictórica contemporáneos inspirados en el pliegue. Revisando el conocimiento adquirido en las diferentes experiencias artísticas en la historia reciente, analizaremos sus soluciones morfológicas y cómo se manifiestan en la actualidad, tomando de ejemplo la pintura de la coruñesa Ángela De la Cruz. ¿Qué papel tiene el pliegue en la pintura actual? Comprobaremos cómo se aplican pictóricamente las potencialidades del pliegue: las dobleces del cuerpo, la teoría de las supercuerdas, los repliegues de la materia sobre los que habla Deleuze... El término “pliegue” abarca una gran variedad de definiciones y aplicaciones en la pintura, desde el tríptico renacentista de Van Eyck, hasta las fisuras vanguardistas en el soporte de Lucio Fontana. Cuando hablamos de pliegues, también hablamos de enrollamientos, bucles, contorsionismos, nudos... Deleuze recupera la idea leibniziana que defendía que todo se encuentra plegado en el universo. Lo que distingue cada uno de estos elementos presentes en el mundo es el modo en el que se encuentra plegado. La arruga, la huella dactilar, las líneas de la mano nos distinguen. El pliegue es aquello que particulariza. Todos los espacios nuevos que crea la misma doblez en el soporte pictórico, las nuevas geometrías y cualidades inéditas. Entenderemos que muchas de las soluciones de la pintura expandida tienen que ver con metáforas antropomórficas. Así, relacionaremos esta doblez en el soporte pictórico con la piel del cuerpo humano. En los pliegues antropométricos de Ángela De la Cruz vemos el reflejo de una visión contemporánea necesaria en nuestro contexto histórico y cultural. Revisitando la obra de filósofos como Byung-Chul Han o Blanchot, comprobaremos como estas dinámicas son la representación (y presentación) de una sociedad que necesita escapar de lo antinatural del bidimiensional, de lo impuro del plano.
Conexiones disciplinarias en una práctica "mestiza”. El caso de la “ornitología emocional”
Authors: Del Junco González Juan José
Published: July 2022

La comunicación que presentamos al congreso analiza y pone en valor una metodología de producción artística inter y transdisciplinaria realizada en los últimos 15 años, la cual pone en liza dos disciplinas a priori exógenas: la práctica artística y la ornitología de campo, en lo que creemos que supone una singular conexión entre campos epistemológicos. A esta alianza la hemos denominado “ornitología emocional”. El devenir lógico de la propia praxis ha posibilitado un crescendo en el grado de cruzamiento. Así, se ha constatado la evolución desde de una primera etapa interdisciplinaria, donde se cooptan, importan los protocolos y lenguajes de disciplinas externas para ser aplicados en nuestra disciplina residente —el arte contemporáneo—, hasta la fusión transdisciplinaria: una suerte de trenzado e imbricación de ambas prácticas aprovechando los intersticios entre sendos ámbitos de conocimiento. La articulación de la metodología se propicia mediante la utilización de aquello que hemos denominado “conceptos procedimentales”, unas herramientas a mitad de camino entre lo discursivo y lo estrictamente procesual, y que, en su pragmática, generan base conceptual y procesual para hacer proyecto. Estos “conceptos procedimentales” se dividen entre los que afectan al protocolo — el método— y los que afectan al lenguaje —la forma—, entendiendo estos últimos como resultados naturales y subsidiarios de los primeros. Entre estas estrategias creativas de carácter instrumental destacamos por un lado el caminar en el paisaje experiencial y el predominio de la observación frente a la mirada por el otro; procesos que se sustentan en ambas orillas disciplinarias, generando en su fin último, una práctica mestiza e indisoluble fundamentada en la propia historia de ambos campos epistemológicos.
El suelo que pisamos
Authors: León Mendoza Raúl
Published: July 2022

El suelo es el plano horizontal donde se realiza una acción (escénica, performativa, cotidiana), sus condiciones de aparente neutralidad se expresan normalmente a través de ciertas convenciones sobre su grado de estabilidad, horizontalidad y consistencia que lo fijan como un elemento puramente funcional y subalterno del mundo. Aquello que denominamos como “el suelo”, determina y delimita una zona con las suficientes dimensiones (largo y ancho) como para podamos entender que no se interrumpe en su continuidad espacial: un plano. Es una superficie que no presenta interrupciones significativas (desniveles) en una extensión suficiente de terreno. Este plano es también continuo en el tiempo puesto que no suele variar de posición (girar o desplazarse) durante el transcurso de determinado lapso de tiempo. Es decir, presenta una estabilidad que se prolonga en el tiempo. El suelo no se mueve. La posición del suelo es fija desde las capacidades perceptivas antropocéntricas. Es, por tanto, una superficie producida, que no nos encontramos por defecto fuera de un contexto de manufactura humana y que requiere de diferentes esfuerzos capaces de transformar una superficie desigual o de construir un plano superpuesto al terreno topográfico de una localización, con unas características concretas y no con otras.Artista, docente e investigador del Departamento de Escultura de la UPV.Sin embargo, desestabilizar esta convención ha sido el objetivo de una serie de arquitectos, directores de escénicos y artistas que han encontrado, en diferentes tentativas de intervención sobre el suelo, un campo de investigación y práctica que les permitía partir de otros presupuestos y forzar nuevas relaciones entre cuerpo y espacio. El presente trabajo, pretende analizar cómo estas tentativas han desplazado las convenciones de posiciones, dinámicas, dimensiones, materialidades y regímenes administrativos del suelo, con una intencionalidad artística y cuál es el sentido del trabajo con un elemento desapercibido y subalternizado y que, sin embargo, nos sustenta.
Problemáticas e incertezas desde aquello inadvertido en las artes visuales
Authors: Luna Crespín Elena
Published: July 2022

Las artes visuales son todo un mundo que queda desatendido desde las administraciones públicas. La carencia de ayudas a este sector cultural pone de manifiesto las inquietudes de los propios agentes sociales que interactúan dentro de este campo del arte visual. El principal objetivo de estudio es la figura del artista visual en el territorio valenciano. Este se encuentra sumergido en su propio campo de trabajo rodeado de constantes obstáculos y dificultades que ponen en peligro su actividad laboral. La finalidad de la investigación es la de analizar los presupuestos generales del Estado dedicados a cultura, los de la Generalitat Valenciana, y los Ayuntamientos de Valencia, Alicante y Castellón, juntamente con las inversiones de las instituciones museísticas, culturales y artísticas valencianas durante los últimos 5/6 años, se consigue un análisis económico que muestra dónde van a parar los capitales económicos en materia de cultura y más concretamente en el arte y artista visual. Los resultados de la presente investigación muestran que el Estado invierte un 12% a nivel nacional en equipos culturales y museos, y alrededor de un 7% en la Comunidad Valenciana. La Generalitat Valenciana invierte un 17,3% en artes visuales. En cuanto a las inversiones directamente relacionadas con el arte; IVAM: 9%, MUVIM: 4%, MACA: 57,7%, MACVAC: 5%, Consorcio: 30% i IVC: 0%. Además, contamos con diferentes entrevistas a los principales gestores y directores de las principales instituciones museísticas, culturales y artísticas valencianas. Desde las propias administraciones públicas valencianas como las instituciones museísticas, culturales y artísticas, se distribuyen estos capitales en función a los objetivos marcados por una estructura envejecida y que parece no seguir las nuevas formas y dinámicas que presenta el campo del arte visual. Palabras clave: artista visual, precariedad, instituciones museísticas, culturales y artísticas, buenas prácticas.
Sensibilidad de Procesamiento Sensorial: El álbum ilustrado como herramienta educativa en la diversidad en España.
Authors: Alvarez Perez Alicia
Published: July 2022

Según la psicóloga Francesca Lionetti un 70% de la población posee cierta sensibilidad y un 30% poseen un rasgo genético y hereditario llamado Sensibilidad de Procesamiento Sensorial, o persona Altamente Sensible (PAS). Estos individuos tienen un cerebro con una mayor reactividad en ciertas áreas, lo que les permite captar más estímulos internos y externos y procesarlos con más profundidad. Es decir, son más sensibles que la media, sin embargo, cuando pensamos en sensibilidad nos vienen a la cabeza frases como “no seas tan sensible” o “no llores tanto”, lo que se deduce con ello que la sensibilidad es percibida en general como una debilidad, algo que no debemos mostrar, a pesar de que más de la mitad de la población es  sensible.Nuestra investigación surge como respuesta a esta visión negativa, que nace y persiste a raíz de los pocos conocimientos que se tienen acerca de la sensibilidad. El objetivo fundamental es demostrar su valor social y educar acerca de su importancia a través de álbumes ilustrados en los que se encuentre además representado este rasgo y puedan servir como herramienta divulgativa y educativa en España. Proponemos el álbum ilustrado como medio por sus múltiples características didácticas, las cuales desde la imagen, ayudan a que los niños y niñas sensibles se sientan representados y se pueda normalizar tanto la sensibilidad como la diversidad de individuos con diferentes sensibilidades. Ayudando con ello a romper con los estereotipos que se nos van inculcando como modelos desde la infancia. De igual manera, tratamos la importancia de una educación que dé respuestas a la diversidad desde las aulas a la sociedad, haciendo frente con ello a una realidad: que no todos aprendemos de la misma manera.
Márgenes temporales: análisis, traducción y construcción de un objeto pictórico múltiple.
Authors: Valverde José Luis
Published: July 2022

El presente proyecto ahonda la relación temporal entre la pintura perteneciente a la tradición pictórica y su recontextualización en los códigos contemporáneos como metodología de producción a través de la traducción. Esta, se proyecta en la construcción del lenguaje del objeto artístico y opera constituyendo la semiótica del medio pictórico. El entrecruzamiento de las distintas líneas de diálogo entre la imagen pictórica y la idea-texto-objeto a la que hace alusión en esa imagen -cuadro-, participan de un proceso de transcodificación. Entendiendo que esto no solo se manifiesta en las metamorfosis conceptuales que atienden a referencias de medios y signos de diferente naturaleza, como puede ser una imagen-texto, sino que también sucede cuando citamos a una referencia del mismo medio (el pictórico). En este caso, la recepción del traspaso de un contenido histórico se transforma, dependiendo del contexto y el marco discursivo en el que se encuentre. Estas, toman otra dimensión al complementarse entre ellas; el espacio narratológico, que vertebra las multiconfiguraciones pictóricas (políptico), se caracteriza porque las diferentes piezas que lo definen, remiten, de manera sistemática, a pinturas concretas, géneros pictóricos, épocas o espacios. Todos ellos potencialmente enfrentados, manifiestan de manera clara la lectura del término intertextual; a partir del cual, se enmarca el campo de juego metodológico del proyecto
MICROPAISAJES PARA EL JUEGO: Interculturalidad urbana desde la experiencia lúdico ambiental en dispositivos instalativos itinerantes
Authors: Goméz Chávez Andrés Eduardo
Published: July 2022

El juego en la ciudad está prohibido y cuando es permitido, está confinado a entornos aburridos, monótonos y arcaicos. Debemos entender el playground o espacio para el juego no como una dispositivo escultórico estático sino como un sistema interactivo multimedia. Este artículo analiza la necesidad de actualización del modelo playground “tipo Mcdonalds” implementado en los 70s, carente de  coherencia con los contextos actuales de jugabilidad, usabilidad e interactividad del mundo digital y videojuegos.Esta propuesta surge así como una reflexión, interpretación y práctica artística personal de la metodología de diseño escenográfico propuesta por Jara Martinez Valderas en su texto Manual de espacio escénico Terminología, fundamentos y proceso creativo. La práctica artística pretende la creación de dispositivos instalativos que al instalarse en un espacio urbano generen de manera temporal una “burbuja lúdica” cuya vocación principal es el juego ambiental y la estimulación cognitivo - sensorial de la población, lo que implica que sean concebidos bajo esquemas de diseño universal e inclusividad. Intentamos proponer una re-contextualización del rol de la escultura como catalizador de actividades en el espacio público y del juego como evento público en cualquier entorno urbano.
Factors contributing to Low Utilization of Sickle Cell services among Caregivers of Children with Sickle Cell Disease at Dr Ambrosoli Memorial Hospital Kalongo, Agago District. A Cross-sectional Study
Authors:   , Ocen Moses
Published: July 2022

Background: Sickle Cell Disease (SCD) is a genetically inherited disease that results in the hemoglobin becoming sickle-shaped in the presence of little oxygen. Utilization of sickle cell services has remained poor despite the discoveries of the screening tests, and the different ways of management, yet the burden of sickle cell is on the rise day by day here in Uganda. The purpose of this study, therefore, was to determine factors contributing to the low utilization of sickle cell services by the caregivers of children with SCD in Dr. Ambrosoli memorial hospital, Kalongo. Methodology: The study employed Quantitative (Researcher-administered structured questionnaires) for the caregivers and qualitative (Key informants) i.e the medical staff in the Paediatric ward and OPD sickle cell clinic. SPSS version 23.0 statistical software was used to generate descriptive statistics. All the information was coded and assigned to the study variables. Results: Results showed high utilization of sickle cell services among caregivers of children with SCD. This is the impact of knowledge about the disease, free services offered, being aware of the sickle cell services offered, negligible side effects of the medications given, good community perceptions about the sickle cell services offered, and good attitudes of health workers when delivering the services. Conclusions: It was found that there is high utilization of sickle cell services among the caregivers, and some factors affect the utilization positively while others negatively. Recommendations: Further research should be conducted to specifically determine the factors contributing to low utilization of Preconception sickle cell screening, to promote prevention rather than management of SCD.

Authors:   , Kikoso Ezera , Kalungi Vincent Charles
Published: July 2022

Background: The purpose of the study was to determine the knowledge, attitude, and practices towards hepatitis B vaccination among patients aged 16- 40 years attending Buwasa health center IV Sironko District. Methodology: The study involved a descriptive cross-sectional study design to address the specific objectives of the study, on a sample of sixty (60) respondents using a simple random technique as the sampling technique. A semi-structured questionnaire was designed and used as a data collection tool. Results: Regarding the practices, the majority (90%) of the respondents reported that they had ever been screened against hepatitis B infection, the majority (87%) of those who reported having been screened negative were initiated on vaccination, and more than half (59%) of them had completed the three doses, among the unvaccinated, the most (47%) frequently mentioned reason for non-vaccination was fear of side effects, more than half (55%) had ever been sensitized about the importance of hepatitis B vaccination. Conclusion: the knowledge of hepatitis B vaccination was poor since most of the respondents did not know the complete hepatitis B vaccination schedule, and the intervals between the doses; with a relatively good attitude and fair practices towards hepatitis B vaccination, and this consequently called for the need to raise patient’s awareness about hepatitis B vaccination to improve on the knowledge, attitude, and practices towards hepatitis B vaccination. Recommendation: The researcher finally recommended that the government of Uganda through the ministry of health should supply adequate vaccine stock to the facility to ensure consistent availability of the vaccine.

Authors:   , Lwasa Nakawooma Hanisha , Nimwesiga Gordon
Published: July 2022

Background: The purpose of the study was to assess the knowledge, attitude, and practices of health workers regarding medical waste management in Entebbe Regional Referral Hospital, Wakiso District. Methodology: The study adopted a cross-sectional study design with a simple random technique as a sampling technique. Data were collected from 50 respondents using a semi-structured questionnaire written in the English language as a data collection tool; later analyzed manually using a scientific calculator, corded and entered into a computer, and presented in tables and figures for easy presentations. Results: All the study participants had ever heard about medical waste management, (60%) were aware of the medical waste management rules and regulations followed in Uganda, (70%) knew 48 hours as the maximum storage period for medical wastes, and (90%) knew segregation, collection and storage transportation, treatment, and disposal as the steps involved in the management of wastes, (50%) knew yellow color code for infectious and (70%) knew gloves as the personal protective equipment used during medical waste management, (94%) of respondents agreed that it is necessary to follow wastes management rules and regulations all the time, (and 52%) were willing to report safety violations done by their fellow workmates regarding waste management and (62%) perceived segregation of hospital wastes to be time-consuming. (90%) of respondents were fully vaccinated for common pathogens. Conclusion: Satisfactory knowledge was associated with favorable attitudes of health workers regarding medical waste management . Recommendation: Entebbe regional referral hospital administration should allocate the tasks and responsibilities to focal persons to properly monitor the medical waste management based on guidelines since the study discovered that some health workers were not following color coding while disposing of medical wastes.

Authors:   , Watmon Erick
Published: July 2022

Background: Sexually transmitted infections especially HIV/AIDS and unwanted pregnancy among students in higher institutions and universities is now a problem yet condom offers protection against sexually transmitted infections including HIV and pregnancy. Despite various promotions, female condom use remains relatively low among students, especially girls. This study purposed to assess the knowledge, attitude, and practice toward female condom use among females of the International Paramedical Institute, Wakiso District Uganda. Methodology: A descriptive cross-sectional study was implemented and a cluster sampling method was adopted to obtain the required number of respondents bringing up to 100 respondents which were got from 134 sample sizes. Results: The results of this study shows that of 100 respondents majority had the good and proper knowledge of female condom and 69(69%) of the respondents agreed that female condom can protect against HIV/AIDS. Regarding attitude toward the use of female condoms, most respondents have a negative attitude as 66(66%) of the respondents agreed that using female condoms reduces sexual pleasure and 84% agreed that FC makes sex uncomfortable. The level of female condom use was as low as only 11(11%) of the respondents. Conclusion; This study, therefore, concludes that the majority of females have does not have a good attitude and does not use female condoms despite having good knowledge of female condom, the level of use is very minimal and irregular. Recommendation: This study, therefore, recommends that for consistent and regular use of a female condom, there is a need to provide better information on a female condoms and make female condoms available and easily accessible to students in various places including hospitals. Better information can be achieved by the introduction of sex education in institutions and universities.
The Energy Pairs Theory
Authors: Segal Moshe
Published: July 2022

The acceptable notion today is that Electromagnetic waves from separate sources cannot consolidate [4]. However, the author of this article published several articles [1], [2], [3], [5] which argue that Electromagnetic (EM) waves from separate sources do consolidate. In addition to the scenarios described in articles [1], [2], [3], Article [5] adds further support to the statement that EM waves from separate sources can consolidate, support that everybody can experience, from everyday experience, every day, which can also be recorded on photos. This scenario is presented again, also in this article. However, if EM waves from separate sources do consolidate, this seems to embed paradoxes, which must be addressed, because the Energy Conservation Principle seems to be violated. The Energy Pairs Theory, proposed initially by the author of this article in article [1], and presented again briefly in this article, proposes a framework which resolves and explains the paradoxes embedded in consolidations of EM waves from separate sources, and other paradoxes and unanswered and open questions, as presented already in article [1], and presented briefly again in this article.
Results of testing varieties of winter triticale for 2019–2021 in the conditions of the north-eastern part of Belarus
Authors: Masterov Alexey , Lupova Ekaterina , Karaulny Dmitry , Plevko Evgeny
Published: July 2022

The total sown area of winter triticale in 2020 in Belarus amounted to 456 thousand hectares. New varieties carry new qualities that need to be studied and compared in specific soil and climatic conditions, to evaluate them in order to make a decision on the possibility of their zoning or culling. The evaluation of varieties was carried out at the SAI "Goretskaya Variety Testing Station" of the Mogilev Region of the Republic of Belarus. The studies were carried out according to generally accepted methods of laying and conducting experiments. Agricultural technology of winter triticale recommended by modern technological regulations for the north-eastern part of Belarus. In total, in 2018–2020, 16 varieties of winter triticale were in variety testing. Average for 2019–2021 Compared to the control variety Dynamo, the variety IZS-3 showed itself better in terms of grain yield (+7.2 c/ha). On average, over the two years above, the yield was higher in the varieties Tadeus (+5.2 c/ha), IZS-5 (+7.0 c/ha), Tribonus (+6.0 c/ha) and Tikhon (+17.2 q/ha). According to the results of one year of testing, the yield of the control variety was higher in varieties IZS-6, IZS-7, Belkanto, Riparo and Rivolt. On the basis of competitive variety testing and assessment of ecological adaptability, it is possible to recommend the IZS-3 variety (Belarus) for inclusion in the State Register of varieties of the Republic of Belarus for cultivation in the conditions of the north-eastern part of Belarus. The varieties Tadeus (Germany), IZS-5 (Belarus), Tikhon (Russia) and Tribonus (Austria) should be recognized as promising. For further variety testing, varieties IZS-6 and IZS-7 (Belarus), Belcanto (Poland), Riparo (France) and Rivolt (France) should be recommended. Keywords: WINTER TRITICALE, VARIETY, COMPETITIVE VARIETY TESTING, YIELD STRUCTURE, PRODUCTIVITY, ECOLOGICAL ADAPTABILITY
Homeless People as Agents of Self-representation: Exploring the Potential of Enhanced Participation in a Community Newspaper Project
Authors: Dvořák Vojtěch
Published: July 2022

Homeless people are subjected to disadvantageous representations in the media, also lacking opportunities for self-representation. This article reports on the findings of two preparatory stages of a project that involves homeless people in the publication of their own newspaper. The findings show that homeless people want to represent themselves through self-created news and to address homelessness as a social issue through people’s life stories, which has the potential to challenge mainstream media practices related to portraying homelessness. At the same time, the analysis reveals several issues that need to be considered while implementing such projects. For example, self-empowerment may sometimes come at the price of disempowerment of others. This emphasizes the importance of carefully structuring the facilitating processes to promote homeless people’s genuine media participation, and to support individual and community empowerment.
Secondary organic aerosol formation via multiphase reaction of hydrocarbons in urban atmospheres using CAMx integrated with the UNIPAR model
Authors: Yu Zechen , Jang Myoseon , Kim Soontae , Son Kyuwon , Han Sanghee , Madhu Azad , Park Jinsoo
Published: July 2022

Abstract. The prediction of secondary organic aerosol (SOA) on
regional scales is traditionally performed by using gas–particle
partitioning models. In the presence of inorganic salted wet aerosols,
aqueous reactions of semivolatile organic compounds can also significantly
contribute to SOA formation. The UNIfied Partitioning-Aerosol phase Reaction
(UNIPAR) model utilizes the explicit gas mechanism to better predict SOA
formation from multiphase reactions of hydrocarbons. In this work, the
UNIPAR model was incorporated with the Comprehensive Air Quality Model with
Extensions (CAMx) to predict the ambient concentration of organic matter
(OM) in urban atmospheres during the Korean-United States Air Quality (2016
KORUS-AQ) campaign. The SOA mass predicted with CAMx–UNIPAR
changed with varying levels of humidity and emissions and in turn has the
potential to improve the accuracy of OM simulations. CAMx–UNIPAR
significantly improved the simulation of SOA formation under the wet
condition, which often occurred during the KORUS-AQ campaign, through the
consideration of aqueous reactions of reactive organic species and
gas–aqueous partitioning. The contribution of aromatic SOA to total OM was
significant during the low-level transport/haze period (24–31 May 2016)
because aromatic oxygenated products are hydrophilic and reactive in aqueous
aerosols. The OM mass predicted with CAMx–UNIPAR was compared with
that predicted with CAMx integrated with the conventional two-product model (SOAP). Based on estimated statistical parameters to predict
OM mass, the performance of CAMx–UNIPAR was noticeably better than that of the
conventional CAMx model, although both SOA models underestimated OM compared
to observed values, possibly due to missing precursor hydrocarbons such as
sesquiterpenes, alkanes, and intermediate volatile organic compounds (VOCs). The CAMx–UNIPAR
simulation suggested that in the urban areas of South Korea, terpene and
anthropogenic emissions significantly contribute to SOA formation while
isoprene SOA minimally impacts SOA formation.
A comparative isotopic study of the biogeochemical cycle of carbon in modern stratified lakes: the hidden role of DOC

Published: July 2022

Abstract. The carbon cycle is central to the evolution of biogeochemical processes at the surface of the Earth. In the ocean, which has been redox-stratified through most of the Earth’s history, the dissolved organic carbon (DOC) reservoir holds a critical role in these processes because of its large size and involvement in many biogeochemical reactions. However, it is rarely measured and examined in modern stratified analogs and yet commonly invoked in past C cycle studies. Here, we characterized the C cycles of four redox-stratified alkaline crater lakes from Mexico. For this purpose, we analyzed the concentrations and isotopic compositions of DOC together with dissolved inorganic and particulate organic C (DIC and POC). In parallel we measured physico-chemical parameters of the water columns and surficial bottom sediments. The four lakes have high DOC concentrations (from ~ 15 to 160 times the amount of POC, averaging 2 ± 4 mM; 1SD, n=28) with an important variability between and within the lakes. All lakes exhibit prominent DOC peaks (up to 21 mM), found in the oxic and/or anoxic zones. δ13CDOC signatures also span a broad range of values from -29.3 to -8.7 ‰ (with as much as 12.5 ‰ variation within a single lake), while δ13CPOC and δ13CDIC varied from -29.0 to -23.5 ‰ and -4.1 to +2.0 ‰, respectively. The DOC peaks in the water columns and associated isotopic variability seem mostly related to oxygenic and/or anoxygenic primary productivity through the release of excess fixed C in three of the lakes (Atexcac, La Preciosa and La Alberca de los Espinos). By contrast, the variability of [DOC] and δ13CDOC in Lake Alchichica could be mainly explained by partial degradation and accumulation in anoxic waters. Overall, DOC records metabolic reactions that would not have been clearly detected if only DIC and POC reservoirs had been analyzed. For example, DOC analyses evidence an active DIC-uptake and use of a DIC-concentrating mechanism by part of the photosynthetic plankton. Despite the prominent role of DOC in the C cycle of these lakes, variations of [DOC]/δ13CDOC and associated reactions are not reflected in the sedimentary organic carbon record, hence calling for special care when considering sediments as reliable archives of metabolic activities in stratified water columns. Overall, this study brings to light the need of further investigating the role of DOC in the C cycles of modern stratified analogs.

Published: July 2022

Abstract. Important topics in Land-Atmosphere (L-A) feedback research are water and energy balances and heterogeneities of fluxes at the land-surface and in the atmospheric booundary layer. To target these questions, the Land-Atmosphere Feedback Observatory (LAFO) has been installed in Southwest Germany. The instrumentation allows comprehensive and high-resolution measurements from the bedrock to the lower free troposphere. Grouped in three components: atmosphere, soil and land-surface and vegetation, the LAFO observation strategy aims for simultaneous measurements in all three compartments. For that the LAFO sensor synergy contains lidar systems to measure the atmospheric key variables humidity, temperature and wind. At the land-surface eddy covariance stations operated to record the energy distribution of radiation, sensible, latent and ground heat fluxes. With a water and temperature sensor network the soil water and temperature is monitored in the agricultural investigation area. The observations in LAFO are organized in operational measurements and intensive observation periods (IOPs). Operational measurements aim for long timeseries dataset to investigate statistics as we present as example the correlation between mixing layer height and surface fluxes. The potential of IOPs is demonstrated with a 24 hour case study with dynamic and thermodynamic profiles with lidar as well as a surface layer observation with the scanning differential absorption lidar to relate atmospheric humidity patterns to soil water structures. Both long-term observations and IOPs are important for improving the representation of L-A feedbacks in climate and numerical weather prediction models.
Effects of point source emission heights in WRF–STILT: a step towards exploiting nocturnal observations in models
Authors: Maier Fabian , Gerbig Christoph , Levin Ingeborg , Super Ingrid , Marshall Julia , Hammer Samuel
Published: July 2022

Abstract. An appropriate representation of point source emissions
in atmospheric transport models is very challenging. In the Stochastic Time-Inverted Lagrangian Transport model (STILT), all point source emissions are
typically released from the surface, meaning that the actual emission stack
height plus subsequent plume rise is not considered. This can lead to
erroneous predictions of trace gas concentrations, especially during
nighttime when vertical atmospheric mixing is minimal. In this study we use
two Weather Research and Forecasting (WRF)–STILT model approaches to simulate fossil fuel CO2
(ffCO2) concentrations: (1) the standard “surface source influence
(SSI)” approach and (2) an alternative “volume source influence (VSI)”
approach where nearby point sources release CO2 according to their
effective emission height profiles. The comparison with 14C-based
measured ffCO2 data from 2-week integrated afternoon and nighttime
samples collected at Heidelberg, 30 m above ground level shows that the
root-mean-square deviation (RMSD) between modelled and measured ffCO2
is indeed almost twice as high during the night (RMSD =6.3 ppm) compared to
the afternoon (RMSD =3.7 ppm) when using the standard SSI approach. In
contrast, the VSI approach leads to a much better performance at nighttime
(RMSD =3.4 ppm), which is similar to its performance during afternoon
(RMSD =3.7 ppm). Representing nearby point source emissions with the VSI
approach could thus be a first step towards exploiting nocturnal
observations in STILT. The ability to use nighttime observations in
atmospheric inversions would dramatically increase the observational data
and allow for the investigation of different source mixtures or diurnal cycles.
To further investigate the differences between these two approaches, we
conducted a model experiment in which we simulated the ffCO2
contributions from 12 artificial power plants with typical annual emissions
of 1 million tonnes of CO2 and with distances between 5 and 200 km from
the Heidelberg observation site. We find that such a power plant must be
more than 50 km away from the observation site in order for the mean
modelled ffCO2 concentration difference between the SSI and VSI
approach to fall below 0.1 ppm during situations with low mixing heights
smaller than 500 m.
What was Killing Babies in Ipswich Between 1872 and 1909?

This paper examines the causes of infant mortality for the port town of Ipswich between 1872 and 1909. Ipswich is the only town in England for which a complete run of computer-readable, individual-level causes of death are available in the late 19th and early 20th century. Our work makes use of the ICD10h coding system being developed to contribute to two projects: Digitising Scotland (University of Edinburgh) and SHiP — Studying the history of Health in Port Cities (Radboud University, Nijmegen). We consider annual and quinquennial mortality rates amongst Ipswich's youngest residents by age, sex, seasonality and cause. The individual causes of death not only offer insight into conditions in the town, but also highlight questions concerning how best to interpret the information provided when both medical terminology and registration practices were changing over the decades of the study. Ipswich infant mortality rates very closely mirrored those of England as a whole, rather than the most unhealthy large cities, such as Liverpool or Manchester. It becomes clear that birth itself was a major cause of neonatal, even some post-neonatal, deaths. While water-food borne diseases killed large numbers in the summer months, it was the ever-present airborne diseases which carried off a greater number of small victims. Although the records offer a rich vein of data to explore, some causes of death, such as convulsions and teething, remain enigmatic and require further research.
Comparative Study of Open Source Content Management Systems (CMS) in Digital Era
Authors: Hembram Mahesh
Published: July 2022

Content Management System (CMS) is the software that can be used to organize, control or manage contents of a website. The data can include texts, links, images, videos, HTML documents and other form of media. The CMS can be free open source software where it can be downloaded and installed free of cost or sometimes it may be a paid depending upon the packages of the software. The reason for the paid software is that some annual maintenance may be needed in future and to upgrade the software. Three basic CMS software Open source, Proprietary and Software as a service has been discussed with their platform of application and supported databases. It was found that this soft ware has used different types of platforms to integrate the software. The installation process of one of the free open source software WordPress also has been discussed in this topic. The purpose of the CMS is to help users to best design their websites. The aim of the study is to comparatively study the features and perspectives of different content management systems. Research and review methodology has been adapted to retrieve the contents for the above title. It was found that maximum number of CMS database used PHP or JAVA platform to design the soft ware and few CMS soft ware used other platforms like ASP.NET, PERL, PYTHON, C++ and others to design the software.

This article presents a SVPWM technique for inverter with two levels to operate the IM drive (induction motor) with Buck Boost converter. SVPWM are increasingly gained importance in high power industrial drive applications. SVPWM technique is preferred in order to decrease the THD value, switching losses and ripples. If any fault occurs in the main supply, the Buck Boost converter which acts as a battery storage device is used as supply to continuously drive the induction without any interruption. The main advantage of Buck Boost converter is it has continuous flow of input current. In the proposed scheme, the two-level SVPWM technique strategy fed IM has been modeled and simulated using MATLAB/SIMULINK software.
Del discurso informal al discurso más formal: ¿Cómo se traducen los textos de promoción turística online del español al ruso?
Authors: Gorozhankina Tamara
Published: July 2022

Debido a una serie de cambios en la comunicación y, sobre todo, promoción turística provocados por la pandemia por SARS-CoV-2, cobra una especial importancia la comunicación turística promocional online. En este sentido, destaca el portal institucional spain.info, una página web de referencia del turismo nacional. Cabe señalar que el género discursivo de los textos promocionales en español destaca por el uso de los deícticos de cercanía, acortando la distancia interpersonal con el lector meta. No obstante, este distanciamiento interpersonal en ruso es mayor, lo que se expresa en los deícticos de cortesía. De ahí surge el interés del presente estudio que radica en ahondar en los rasgos lingüísticos que tienen que ver con el uso de los deícticos y las formas personales e impersonales en el discurso turístico.
La traducción de cartas de restaurante en un destino turístico: un estudio de caso

Published: July 2022

La presencia de turismo francófono en Canarias parece contrastar con las deficiencias presentes en la versión francesa de los menús de restaurantes de un relevante espacio turístico de Canarias. Así, se han recabado datos sobre el terreno para constituir el corpus de este estudio: 18 cartas reales en francés y español de restaurantes situados en primera línea de playa. Desde el punto de vista metodológico, tras la definición del corpus, se ha caracterizado el tipo textual y se ha analizado su traducción, en especial, la de los abundantes culturemas presentes en este tipo de textos. Se pretende, así, ilustrar las técnicas empleadas para su traducción, detectar los posibles errores y proponer soluciones alternativas, con el fin último de que la traducción contribuya a transmitir claramente la realidad cultural del destino turístico.
Delivery mode selection of home furnishing e-retailer based on a combination of logistics delivery and installation service

With the increasing demand for online home-furnishing products, product delivery services, especially installation services, have become increasingly regarded as bottlenecks and key factors for success. Meanwhile, customers have different preferences for a combination of delivery modes because of separated or synchronized logistics delivery from installation services. It is essential for online home-furnishing e-retailers to self-build or outsource installation services. This study investigates the optimal delivery mode selection of home-furnishing e-retailers in a home-furnishing supply chain consisting of a home-furnishing e-retailer, a third-party installation service provider (ISP), and a third-party logistics service provider (LSP). Specifically, we explore three alternative modes: (ⅰ) The home-furnishing e-retailer undertakes the installation service (Mode E); (ⅱ) the ISP undertakes the installation service (Mode I); (ⅲ) the LSP undertakes the installation service (Mode L). The results reveal that the self-build mode does not always generate the highest installation service level, and the integrated delivery mode may generate the highest installation service level when the cost performance of the installation service is relatively low. Moreover, optimal delivery mode selection depends on the installation service’s cost performance. When the installation service’s cost performance is relatively low, the e-retailer and the LSP reach a “win-win” situation from the integrated delivery mode. When the installation service’s cost performance is relatively high and the self-build fixed cost is low, the e-retailer and the LSP reach a win-win situation from the self-build mode. Interestingly, compared with the outsourced integrated service mode, the self-build integrated service mode is not a better choice for the e-retailer if the self-build fixed cost is too high. Our study contributes to the growing literature on home furnishing and guides the implementation of delivery strategies for large-product online retailers.
