Nuevas tecnologías y divulgación científica: el caso de la app Hidden Valencia
Authors: LLanes Parra Blanca
Published: January 2022

Hidden Valencia es una aplicación móvil que se ha elaborado en el marco del proyecto europeo PURE (Public Renaissance: Urban Cultures of Public Space between Early Modern Europe and the Present), liderado por la Universidad de Exeter, y en el que participa la Universidad de Valencia, entre otras universidades europeas. El proyecto engloba un equipo interdisciplinario de investigadores pertenecientes a los ámbitos de la historia del arte y de la arquitectura, a la historia social y a la historia cultural, trabajando en colaboración con socios o agentes externos al mundo académico, principalmente vinculados al sector de los museos y del patrimonio, para poner en dialogo nuestra investigación como historiadores con las cuestiones que preocupan hoy en día a los urbanistas, arquitectos y legisladores contemporáneos, indagando en las continuidades y rupturas que configuran los espacios urbanos del pasado en relación con la interacción urbana del presente. Hidden Valencia se integra dentro del grupo de aplicaciones móviles Hidden Cities, inspiradas en el modelo de la pionera app Hidden Florence, y cuya premisa básica sería la de invitar al usuario a adentrarse en el pasado de cinco ciudades europeas, Deventer, Exeter, Hamburgo, Valencia y Trento con la ayuda de un mapa histórico geolocalizado y de la mano de guías de los siglos XV al XVII. Así, la aplicación Hidden Valencia, y en concreto su recorrido “Valencia agermanada”, permite al usuario a sumergirse en los dramáticos acontecimientos de la revuelta de las Germanías (1519-1522), con un guía muy especial, Josep, un ciego oracionero valenciano miembro de la cofradía de la Vera Creu. Lo que persigue la app es que el usuario pueda rastrear y descubrir las huellas del espacio público de la Valencia de principios del siglo XVI en la Valencia de hoy en día, enfatizando su conexión con los sucesos de la Germanía. En su recorrido por la ciudad, Josep desvela, además, cómo era la vida cotidiana de un ciego oracionero en la Valencia de la Edad Moderna. Tomando como estudio de caso la aplicación móvil Hidden Valencia, en la presente comunicación se analizará, por tanto, el papel de las nuevas tecnologías en la difusión y divulgación del conocimiento histórico y artístico, enfatizando la idoneidad del uso de medios locativos con esta finalidad didáctica y de compromiso público.

Retrato de una Cerilla. El Ensayo Audiovisual como Posicionamiento Crítico en la Sociedad del Rendimiento
Authors: García de Mateos Sanchis Claudia
Published: January 2022

Byung-Chul Han, en La sociedad de la transparencia (2013), describe el síndrome psíquico de Burnout. En resumen, es un estado de agotamiento físico, emocional o mental, un cansancio emocional que provoca la despersonalización, con consecuencias para la autoestima así como la pérdida del interés y el sentido de la responsabilidad. Esta situación ha sido provocada y aprovechada por el neocapitalismo liberal, ofreciendo la oportunidad de suplir ese vacío existencial con la realización personal a través del trabajo, de la producción. Sin embargo, para hacer esto posible, no se ejerce una violencia física externa que obliga, propia de una sociedad disciplinaria, sino que viene de una voz interna identificada como personal y propia que repite en bucle que siempre es posible hacer un poco más para llegar un poco más alto y ser un poco mejor que ayer. ¿Cuál es el origen de esta necesidad? ¿Es natural la constante propuesta de superación y mejora? ¿Es posible detectar y parar esos mecanismos neuronales que obligan al sujeto a rendir hasta límites insanos física y mentalmente? Retrato de una cerilla. Bloque I: Identificación es un ensayo audiovisual que conforma la primera parte de una investigación audiovisual compuesta de cuatro bloques transdisciplinares en relación con los mecanismos individuales y sociales que potencian la violencia neuronal derivada del autorrendimiento. El proyecto nos plantea una cuestión clara: ¿la autoexigencia que se ha llegado a comprender como parte intrínseca de la personalidad es natural o es, por el contrario, un comportamiento inducido y naturalizado hasta el punto de hacerlo pasar como propio? A través de las aportaciones conceptuales y formales de lenguajes audiovisuales tales como el apropiacionismo y el uso de montajes de corte rítmico e intelectual, Retrato de una cerilla defiende el arte como crítica y resistencia al nuevo modelo de sociedad derivado del neocapitalismo postmoderno.
El problema de la sobrexposición en las redes sociales visto a través del arte: posverdad y lifelogging
Authors: Hernández Acuaviva Helena
Published: January 2022

El arte toma el pulso de la sociedad. Expuesta a sus constantes cambios y avances, la creación artística ha experimentado un cambio de paradigma en las últimas décadas, coincidiendo con la aparición de Internet y la Web 2.0. La red es un gigantesco almacén virtual de registro de datos en actualización continua, donde todo se puede encontrar, y un espacio colaborativo de interconexión entre personas de cualquier lugar del mundo. En estado beta permanente, la Web social se nutre y evoluciona aprendiendo de los usuarios y ofreciendo nuevos niveles de experiencia en base a sus necesidades y deseos; lo que, a su vez, incrementa el empleo de la red. Este creciente uso de las redes sociales y las plataformas colaborativas ha causado un importante impacto en nuestros modos de pensar, mirar y reaccionar frente al mundo y, también, en las formas de expresión artística. En el territorio digital los límites de producción, transmisión y recepción de imágenes se diluyen. El arte hoy, no es estático ni unidireccional, sino que circula, se reutiliza y cambia. La condición virtual de la imagen contemporánea lleva asociadas las ideas de velocidad, saturación y posverdad.  Nuestro objetivo es estudiar cómo el arte último se adapta al espacio global de las redes sociales y cómo el pensamiento artístico asimila sus modos de hacer, su estética y su lenguaje. Apoyándonos en el análisis de las propuestas artísticas de creadores comprometidos con la reflexión en torno al empleo de las redes sociales, evidenciaremos problemáticas actuales relacionadas con la saturación del yo, y la credibilidad informativa, afectada por el fenómeno de la posverdad y el fake. De la misma forma, abordaremos el dilema de la privacidad de los usuarios y deliberaremos sobre las implicaciones de la sobreexposición de nuestras vidas en las redes, atendiendo a fenómenos relativamente recientes como el denominado lifelogging. Haremos hincapié en estas ideas utilizando como ejemplo creaciones digitales intermediadas por la pantalla, ya sean diseñadas a través de una aplicación específica o pensadas para su desarrollo dentro de las propias redes sociales, de naturaleza fundamentalmente videográfica. Así, utilizando el arte como sensor, trataremos de concluir qué hay detrás de las imágenes objeto de estudio: el contexto en el que surgen -bajo la urgencia del ritmo sin pausa de Internet y las redes sociales-; el modo en el que se construyen y distribuyen -imágenes de baja resolución guardadas automáticamente en la nube y en nuestros dispositivos-; y el uso que hace el usuario de ellas -multiplicación, reenvío, visualización efímera-. Proponemos, en definitiva, un acercamiento reflexivo a los conflictos asociados al uso de Internet y las redes sociales utilizando el arte como mediador.
Translations, un poema audiovisual.
Authors: Rodríguez Arias Ángel Manuel , Kim Ji Yeon
Published: January 2022

Translation, en inglés, es un término que define, por una parte, el acto de traducir de un idioma a otro, y por otra, el de trasladar de un lugar a otro. Urdiendo un juego con el doble sentido de esta expresión, la síntesis de este ensayo audiovisual se basa dentro de una dinámica introspectiva, en definir el vínculo entre dos culturas, y dos lugares; Galicia y Corea, a través de una mirada íntima en la que se resarza al sujeto subalterno.Partiendo del constructo Oriente-Occidente, como explica Edward Saíd, el primero es visto como un amalgama en el que lo místico y lo exótico se observan con deseo,  siempre desde una posición superior. El término se trata en sí mismo de una forma de reafirmarse a sí mismo; al hombre, blanco, europeo, cristiano y endocéntrico, frente al resto.En consecuencia, tomando estos conceptos como una forma de comprender la propia identidad subjetiva de una mujer migrante, la estructura de esta experimentación se basa en una serie de intervenciones en el paisaje, en distintos territorios. De este modo, una estructura portátil y desmontable es colocada en un bosque, un arroyo o un lago. Estos espacios, esconden lugares en los que las personas se asentaron antaño, pero hoy permanecen olvidados. El color blanco y sus significaciones en el folclore de ambas culturas; pureza, vida, fragilidad o muerte, servirán, en definitiva, de elemento vertebrador que da sentido a la secuencia de imágenes y sonidos, las cuales se interrelacionan a través de este análisis comparativo.
The acceptance of ephemerality and the idea of deterioration.
Authors: DEL FRESNO-GUILLEM RUTH
Published: January 2022

In an era of technology-based life, we might understand the language but not pay attention to the message. Conservators, historians, curators, collectors have been focusing their efforts on finding strategies to preserve, document, exhibit, sell and maintain the idea of authenticity. It is essential to discuss and re-define our limits, the ethics that concern these “new” languages. Languages have been around for almost half a century, but we still think they are new technologies. From the Performance Art, art-related professionals learned that sometimes art is like a smell; it is there, you can feel it, you can store it in your inner brain, describe it, and remake it, but it is not there. We accept strategies that help the market, the history, the institutions, the collectors. We all play the same game with different hats. However, what when the artist explicitly says no. In a previous Ph.D. research, a study on the use of the artist’s interview; the aim of this research was not to show how good the artist’s interview was, as it had been long proved, but to collect and compare the results, the mistakes, the human part of the creative process and the conservation field. Making questions is one of the essential parts of the research, and most of the time, not an answer can be found, not even the shadow of an academically accepted answer, but some other smells were found. This abstract wants to expose the case study of a piece made to stay for the period that technology and life permitted; an image made with an old technology telephone, one printed copy, on a low-quality paper, framed with an Ikea frame. No replacement is allowed, no treatments, no migration or storage of the file. The interview helped to understand the idea of deterioration. An idea linked to the durability and acceptance of its death.  Are we ready to accept the real ephemerality? Do we understand the preservation of the idea of deterioration? Is the collector, the institution, ready to enjoy while it lasts? This presentation can be delivered as a talk or as a conversation with the artist involved in the study case.

Towards a framework for Improved Organizational Performance at the Department of Transport, eThekwini region
Authors:   , Martin Adele Alice
Published: January 2022

For more than a decade, the South African local government has been in the spotlight for the provision of appalling services, resulting from the incompetency and inefficiency of South African public servants. The introduction of a performance management system (PMS) is expected to safeguard the utilization of resources more efficiently and to ensure that objectives of an organization are appropriately implemented towards yielding the desired growth impacts. However, the current PMS utilized within South African government departments presents one key concern regarding the effective management of employee performance. This research examines the implementation and effectiveness of the current PMS in the Department of Transport, eThekwini region.
Estimation of Cooling Load Temperature Diffrence for Exterior Walls of Buildings Located in Tripoli, Libya
Authors: Alhoush Abdulhakiem , Alghoul Samah , Hawisa Jamal
Published: January 2022

A good estimate of the cooling load is one vital aspect for achieving the optimal level of comfort and energy effiency in buildings. Due to its relative simplicity, the Cooling Load Temperature Diffrence (CLTD) method is still used both in education and industry for cooling load calculations. However, one downside of using this method is the limited number of walls and roofs which do not represent effctively all commonly used wall and roof constructions. In this research, a transient heat transfer model was developedto fid the (CLTD) values, for the most common external walls of buildings that have widespread use in Tripoli, Libya. Th Finite diffrence method was used to solve the governing partial diffrential equations with appropriate initial and boundary conditions. A MATLAB program has been developed and used to solve the system of algebraic equations produced by applying the fiite diffrence method to the governing diffrential equations. A comparison has been made between the computed results and ASHRAE CLTDvalues. At standard conditions specifid in ASHRAE handbooks for the same wall with a default composition, a reasonably good agreement was found between computed and ASHRAE CLTD values for this wall. CLTD values have been generated for three diffrent types of walls; Hollow concrete block, Limestone block, and Hollow brick. With these values, the cooling load calculation of buildings can be easily and manually performed with more accuracy. It is also concluded from the transient analysis that the limestone block walls provide the best therm.
Wind Energy Resources Estimation and Assessment For AL-Maqrun Town - Libya
Authors: Ahwide Farag , Ismail Anwar
Published: January 2022

Fossil fuels (Natural gas, heavy and light oil) are considered the main sources of electricity generation in Libya. Libya’s electricity demand is growing at a rapid rate and the country will require significant additional capacity in the coming years due to the development of all sectors of life and the improvement of individuals’ life quality, without taking into account the rationalization of electricity consumption. The main reason for this is that Libya has a very high energy subsidy, especially the tariff set by the Libyan state for the price per kilowatt-hour for the electricity sector. The heavily subsidized electricity price for households currently stands at (20 dirham’s/kilowatt-hour) compared to (100 dirham’s/kilowatt-hour), as the domestic price of fuel cost, and in return (450 dirham’s/kilowatt-hour) as the electricity cost of fuel in international prices. In order to reduce the deficit and the ongoing balancingin energy demand with the amount of generation of available capacity, it is necessary to study all electrical systems for the future, the most important of which are wind energy and solar energy projects to meet a significant part of this demand and to reduce, as much as possible, the carbon dioxide emissions. This paper deals with the wind data processing at the site coupled with the city and its relationship to electricity generation. It presents long-term wind data analysis, in terms of averages of ten-minute values of wind speed were used to get yearly mean values for a period of 1 year, between 04/11/2002 and 30/12/2003. The most frequent winddirections are NW, N, NNW, and WNW. They represent about 50%, followed by E, ESE, and SE. In general, East and SE winds are relatively frequent but weak at the same time. The most powerful directions are NW, WNW, W, and NNW which by far - represent about 46% of the expected power, followed by N. It should be noted that the high frequency of north direction winds that come from the desert can cause a high frequency of dust episodes. The fact should be taken into consideration in order to take appropriate measures to prevent wind turbine deterioration. The annual energy yield and wind direction were evaluated for AL-Magrun town, considering wind turbines ranging between 1.65 MW and 2 MW (power curve considering air density 1.225 kg/m3). The wind turbine (Gamesa 90/2000) recorded the highest values, equaling (6.05GWh,3023Eqh) and (M. Torres TWT 1.65-82 ) equaling (4.39GWh, 2660 Eqh) compared to the rest of the turbines studied. Those values encouraged us to take advantage of wind power to achieve economic benefits.
Effct of Full Implementation of Domestic Solar Water Heaters on the Electricity Peak Load in Libya
Authors: Abdunnabi M. J. R. , Dadesh K. , Mrehel O. R. , El-shamekh N.
Published: January 2022

Electricity plays an important role in contemporary life, and it has become indispensable nowadays. Reducing the peak electricity load and increasing the load factor have been considered as one of the main tasks that have to be accomplished by both electricity generation-side and demand-side management. The residential sector of Libya consumes over 31% of the total sold electricity, and 29.8% of that is delivered to the electric water heating load. This is an inefficient way of electricity utilization. Usually, the electricitysupplier in Libya is used to increase the local generation capacity or import electricity from neighboring countries. Both solutions did not resolve the problem. This work attempts to investigate the effect of replacing electric water heaters in the residential sector of Libya with solar water heaters on reducing the electricity peak load and increasing the load factor. Th results show that on average 3% of the peak load demand can be saved.This is equivalent to 149.5 MW of reduced power. The study also revealed that the annual amount of energy saved is up to 2.55TWh, and the load factor is improved by 2% (i.e. from 65% to 67%). This saved energy is equivalent to a power plant with a nominal capacity of 448 MW considering a load factor of 0.65
Simulation Of Indirect Solar Crop Dryers Augmented With Pebble-Bed Thrmal Storages
Authors: Elbenghazi E. , Agha K. , Dekam E.
Published: January 2022

This paper presents a model of indirect solar dryer augmented with pebble bed thermal storage. The thermal storage system was considered to be placed inside the drying chamber above the 47°-tilted air solar collector and below the crop bed, where an average September-daily insolation profile was given for the 32°N location. A presented mathematical model took into consideration the pressure and natural buoyancy forces, employed the basic governing equations, atmospheric-air psychometric-chart relations, and published correlation relationships. A “QBASIC” computer program was written based on the trial and error method for the calculation of different parameters. Dimensions of the dryer system, position, and characteristics of the crop and storage beds, strongly affected the behavior of the dryer system, for both rice and tomato products.  Referring to the considered indirect solar dryer design type, on average two and five days were required for rice and tomatoes long-term drying, respectively. This seems to be visible in rice products, however, it is far from applicability for tomatoes mass-drying process in agricultural fields, due to its high initial moisture content.

Authors: Abdalla A , El-Osta Wedad , Dekam E
Published: January 2022

The lowest portion of the atmosphere is vital to lives, infrastructure, and activities. It means air quality, air motion and momentum, solar and wind energy, and weather safety measures. Wind speed observations at three diffrent heights for three Libyan coastal sites; Magron, Musrata and Darnah, were documented and analysed. Wind speed profies were estimated employing the two common methods: logarithmic wind and power law profies. Th seasonal and annual patterns, and atmospheric stabilityclassifiations were obtained. Th daily wind shear variation and wind velocity profies were determined at diffrent atmospheric stability conditions, neutral, stable and unstable.The results confim that the highest wind shear occurs during stable conditions at night and for longer in winter days, and the lowest during unstable and neutral atmospheric conditions near midday specially in summer days. Non-dimensional wind speed profies were obtained and their behaviour was identifid and compared. Th available wind energy history was evaluated considering the effct of atmospheric stability conditions on the estimated extracted energy for each site
New Designed Thermosyphon Solar Water Heater with Small Sized Parabolic Trough Collectors
Authors: Saed Jehad , Abdunnabi Mohammad , Essnid Akram , Buishi Ahmed
Published: January 2022

In this paper, the performance of thermosyphon solar water heater of small-sized parabolictrough collectors has been experimentally investigated under Libyan climate. The solar collectors were fabricated from the locally available materials. The thermosyphon system consists of two parabolic troughs with 3.16 m2 aperture area and a storage tank of 170 liters. It is erected in the main outdoor testing area at the Center for Solar Energy Research and Studies for thermal performance evaluation. Twenty days of experiments were considered for the analysis of the new system performance. Th experimental results showed that the maximum outlet temperature of withdrawn hot water at the end of the day was 73.4 °C for a daily solar insolation of 27.67 MJ/m2 and diffse ratio less than 18% (clear sky). Whereas, the minimum hot water withdrawn temperature was 37 °C with daily solar insolation of 12.82 MJ/m2 and diffse ratio over 61%. The system performance decreases as the diffse ratio increases due to the nature of concentrating technology. The input/output characteristics equation of the system is obtained and the performance is compared with similar systems of the same size and diffrent collection technologies. Th compassion showed a competitiveperformance compared to other technologies.
Low Cost High Altitude Automatic Weather Station Design
Authors: Dadesh Khaled , Ben Rhouma Saif
Published: January 2022

When looking at installing a renewable energy generator, you need to be confient of the resource (solar, wind) at your particular location as this affcts the energy generated at the selected site. With solar photovoltaic (PV) systems, this can be done by looking at historic data, generally from satellite readings, for the particular latitude. Ths will yield pretty accurate resource data. However, the wind resource is incredibly variable and depends upon the exact topology of the area. Houses, trees, and valleys all can affct the local wind resource. For this reason, wind speed data is collected at a potential wind turbine installation site. This gives real data which can be used to assess the wind speed. When installing a number of very expensive large wind turbines, one must be very confient about the wind speed data. Th data must be robust and reliable and the developer will be willing to spend a lot of money on accurate industrial equipment to have lots of confience in the data. Ths project intends to overcome this barrier by providing a low-cost, reusable, opensource wind speed recording unit, which can be lef at high altitude in a remote location to record data and help improve the site’s wind speed assessment. We have proposed and developed a low-cost hardware module based on Arduino open source platform, which measures the meteorological data, including air, temperature, relative humidity, wind speed and solar radiation, with two options: Th fist is the wireless option at which it sends the measured information to Excel spreadsheet running on a PC through wireless link. The second is the data logger option at which it records the measured data to SD card as Excel fie with date and time every 10 seconds.

Published: January 2022

The main objective of the present paper is to compare nine diffrent cell temperature models available in the literature with data measured under real Derna city climatic conditions (a semi arid climate) for month of August. Th study focuses on a comparison of nine theoretical models to calculate the cell temperature based on the experimental measurements such as the ambient temperature, irradiance, and wind speed in some of the models. Th presently used models are explicit, depending on the easily measurable parameters and of wide applicability. Six statistical quantitative indicators are used to evaluate the cell temperature models analysed, namely, R2, RMSE, RRMSE, MAE, MBE and MARE. The cell temperature correlations presently studied, fist order linear models depending on the ambient temperature, solar irradiation incident on the panel and voltage output, provide the most accurate cell temperature estimations at Derna city climatic conditions
The Correlation of Palladium Supported Carbon (Pd/C) Loading and Optimum Nafin Ionomer Weight Percent (wt.%) Content in the PEM Fuel Cell Catalyst Layer
Authors: Sghayer Abdulhamed , Diyaf Adel , Mazuz Khaled , Issa Naji
Published: January 2022

The presence of Nafin ionomer as one of basic elements in the PEM fuel cell catalyst layer structure can extend the three phase contact between the reactant gases, electrolyte and the catalyst surface and make the catalyst layer active in three dimensions, since the proton can move throughout the entire catalyst layer, which would improve the PEM fuel cell performance. Th main objective of this study is to examine the dependence of the optimum Nafin ionomer weight percent (wt.%), on the palladium supported carbon(Pd/C) loading in PEM fuel cell catalyst layer. Th results showed that the optimum Nafin ionomer contents in the PEM fuel cell catalyst layer is dependent and inversely proportional to the amount of Pd/C loading. For catalyst layers with a Palladium supported carbon (Pd/C) loading of 4.0 ± 0.1 mg/cm2, 3.2 ± 0.1 mg/cm2, and 2.45 ± 0.05 mg/cm2, the best performance was obtained at about 33, 35, and 37 wt.% Nafin ionomer loading respectively

Global, regional and seasonal analysis of total ozone trends derived from the 1995–2020 GTO-ECV climate data record

Abstract. In this study we present an updated perspective on near-global total ozone trends for the period 1995–2020. We use the GOME-type Total Ozone Essential Climate Variable (GTO-ECV) satellite data record which has been extended and generated as part of the European Space Agency’s Climate Change Initiative (ESA-CCI) and European Union Copernicus Climate Change Service (EU-C3S) ozone projects. The focus of our work is the analysis of regional patterns in the ozone trend as well as the investigation of its seasonal dependence. In the Southern Hemisphere we found regions that indicate statistically significant positive trends increasing from 0.6 ± 0.5 % decade−1 in the subtropics to 1.0 ± 0.9 % decade−1 in the middle latitudes and 2.8 ± 2.6 % decade−1 in the latitude band 60°–70° S. In the middle latitudes of the Northern Hemisphere the trend exhibits distinct regional patterns, i.e. latitudinal and longitudinal structures. Significant positive trends (∼1.5 ± 1.0 % decade−1) over the North Atlantic region as well as negative trends (−1.0 ± 1.0 % decade−1) over Eastern Europe were found. Moreover, these trends indicate a correlation with long-term changes in tropopause pressure. Total ozone trends in the tropics are not significant. Regarding the seasonal dependence of the trends we found only very small variations over the course of the year. However, we identified different behavior depending on latitude. In the latitude band 40°–70° N the positive trend maximizes in boreal winter from December to February. In the middle latitudes of the Southern Hemisphere (35°–50° S) the trend is maximum from March to May. Further south toward the high latitudes (55°–70° S) the trend denotes a relatively strong seasonal cycle which varies from 2 % decade−1 in December and January to 3.8 % decade−1 in June and July.
Duff burning from wildfires in a moist region: different impacts on PM2.5 and ozone

Published: January 2022

Abstract. Wildfires can significantly impact air quality and human
health. However, little is known about how different fuel bed components
contribute to these impacts. This study investigates the air quality impacts
of duff and peat consumption during wildfires in the southeastern United States, with a focus on the differing contributions of fine particulate matter less
than 2.5 µm in size (PM2.5) and ozone (O3) to air
quality episodes associated with the four largest wildfire events in the
region during this century. The emissions of duff burning were estimated
based on a field measurement of a 2016 southern Appalachian fire. The
emissions from the burning of other fuels were obtained from the Fire
INventory from NCAR (FINN). The air quality impacts were simulated using a
three-dimensional regional air quality model. The results show the duff burning emitted PM2.5 comparable to the burning of the above-ground fuels. The
simulated surface PM2.5 concentrations due to duff burning increased by
61.3 % locally over a region approximately 300 km within the fire site and
by 21.3 % and 29.7 % in remote metro Atlanta and Charlotte during the 2016 southern Appalachian fires and by 131.9 % locally and by
17.7 % and 24.8 % in remote metro Orlando and Miami during the 2007 Okefenokee Fire. However, the simulated ozone impacts from the duff burning were negligible due to the small duff emission factors of ozone
precursors such as NOx. This study suggests the need to improve the
modeling of PM2.5 and the air quality, human health, and climate
impacts of wildfires in moist ecosystems by including duff burning in global
fire emission inventories.
Eight-year variations in atmospheric radiocesium in Fukushima city
Authors: Watanabe Akira , Kajino Mizuo , Ninomiya Kazuhiko , Nagahashi Yoshitaka , Shinohara Atsushi
Published: January 2022

Abstract. After the Fukushima nuclear accident, atmospheric
134Cs and 137Cs measurements were taken in Fukushima city for
8 years, from March 2011 to March 2019. The airborne surface
concentrations and deposition of radiocesium (radio-Cs) were high in winter and low in
summer; these trends are the opposite of those observed in a contaminated
forest area. The effective half-lives of 137Cs in the concentrations
and deposition before 2015 (0.754 and 1.30 years, respectively) were
significantly shorter than those after 2015 (2.07 and 4.69 years,
respectively), which was likely because the dissolved radio-Cs
was discharged from the local terrestrial ecosystems more rapidly than the
particulate radio-Cs. In fact, the dissolved fractions of precipitation were
larger than the particulate fractions before 2015, but the particulate
fractions were larger after 2016. X-ray fluorescence analysis suggested that
biotite may have played a key role in the environmental behavior of
particulate forms of radio-Cs after 2014. However, the causal relationship
between the seasonal variations in particle size distributions and the
possible sources of particles is not yet fully understood. The current study
also proposes an evaluation method of the consistency of a numerical model
for radio-Cs resuspension and suggests that improvements to the model are
necessary.
Measurement and optimization of a continuously tunable 10×10 reflectarray antenna for 5G metrology in the K-band
Authors: Harz Thomas , Kleine-Ostmann Thomas
Published: January 2022

Abstract. A functional 10×10 reflectarray antenna is developed for
millimeter-waves. It has a gain of approximately 10 dBi and a continuous
steering range from −30 to 30∘ in the horizontal plane.
In this paper, the entire design process is explained, beginning with the
design and function of the antenna element and followed by considerations
regarding positioning of the feed antenna. Steering and controlling of the
beam are discussed. Finally, the antenna patterns for different steering
angles were measured in an anechoic chamber. The design is scalable, built
with commercial off-the-shelf components, and the array does not need active
cooling.
A simplified isotope dilution approach for the U–Pb dating of speleogenic and other low-232Th carbonates by multi-collector ICP-MS
Authors: Mason Andrew J. , Vaks Anton , Breitenbach Sebastian F. M. , Hooker John N. , Henderson Gideon M.
Published: January 2022

Abstract. We describe a new method for the measurement of U/Pb
ratios by isotope dilution multi-collector inductively coupled plasma mass
spectrometry (MC-ICP-MS) for the dating of geologically young clean
carbonates, particularly speleothems. The method is intended for materials
containing little or no initial 232Th. We illustrate and validate the
method with four examples ranging from 0.57 to 20 Ma. The new method
is capable of applying the 235U–207Pb and
238U–234U–206Pb chronometers, common Pb and quantifiable
residual 234U/238U disequilibrium permitting. These provide an
alternative to the more widely used 238U–206Pb chronometer, which
can be highly inaccurate for samples that are < ca. 20 million years old,
owing to uncertainties in the excess initial 234U (hence, excess
radiogenic 206Pb) commonly observed in speleothems.
Evaluation of the COSMO model (v5.1) in polarimetric radar space – impact of uncertainties in model microphysics, retrievals and forward operators

Published: January 2022

Abstract. Sensitivity experiments with a numerical weather prediction (NWP) model and polarimetric radar forward operator (FO) are conducted for a long-duration stratiform event over northwestern Germany to evaluate uncertainties in the partitioning of the ice water content and assumptions of hydrometeor scattering properties in the NWP model and FO, respectively. Polarimetric observations from X-band radar and retrievals of hydrometeor classifications are used for comparison with the multiple experiments in radar and model space. Modifying the critical diameter of particles for ice-to-snow conversion by aggregation (Dice) and the threshold temperature responsible for graupel production by riming (Tgr), was found to improve the synthetic polarimetric moments and simulated hydrometeor population, while keeping the difference in surface precipitation statistically insignificant at model resolvable grid scales. However, the model still exhibited a low bias (lower magnitude than observation) in simulated polarimetric moments at lower levels above the melting layer (−3 to −13 ∘C) where snow was found to dominate. This necessitates further research into the missing microphysical processes in these lower levels (e.g. fragmentation due to ice–ice collisions) and use of more reliable snow-scattering models to draw valid conclusions.
Review article: Factors leading to the occurrence of flood fatalities: a systematic review of research papers published between 2010 and 2020
Authors: Petrucci Olga
Published: January 2022

Abstract. Floods kill numerous people every year in both developed and developing
countries. The transfer of research findings from the academic community to
practitioners, policy-makers and citizens may reduce the impact of floods on mortality. This systematic review analyzes 44 scientific articles extracted from WOS and SCOPUS databases written in English, published between 2010 and 2020, and focuses on flood fatalities. The first main finding of this review is the classification of drivers of flood mortality into two groups: the first group relates to the environment, and the second group relates to the fatalities. The second main finding is the identification of strategies to practically cope with the identified drivers of flood fatalities. The main shortcomings of the review concern (a) the unavailability of papers based on flood fatality occurrence in developing countries and (b) the absence of data focusing on people who have survived floods. This review amplifies useful findings, best practices and lessons learned that can be useful for administrators, risk managers, and teachers of primary and secondary schools to mitigate the impact of future floods on human life.
