Wizarding World Book Club e a ampliação do universo narrativo: uma análise das ações e das estratégias na rede social digital a partir do clube do livro de Harry Potte
Authors:   , Martins Vanessa Coutinho
Published: March 2021

A partir das relações entre os indivíduos que se estabelecem no campo da comunicação midiática, esta dissertação tem como ponto de partida o conceito de deslizamento da narrativa (FIGUEIREDO, 2010, 2020a), especificamente no ecossistema digital, que proporciona interações em rede. A pesquisa desenvolve um estudo sobre o Wizarding World Book Club, clube do livro de Harry Potter criado pelo Pottermore (atual Wizarding World), ambiente em rede oficial da saga. O Book Club foi criado em comemoração aos 20 anos de lançamento do primeiro livro da saga (em seu idioma original, inglês), “Harry Potter e a Pedra Filosofal”, com início em 2017 e finalizando suas atividades em 2018. O clube do livro teve como rede social digital central o Twitter, mas apresentou desdobramentos no Facebook, Instagram, Snapchat e Periscope, além do site oficial do universo narrativo em questão, o pottermore.com. Busca-se, nesta dissertação, entender quais foram e como funcionaram as estratégias do Wizarding World Book Club e quaissuas consequências. Como corpus de análise da conversação em rede, o fluxo conversacional proveniente do Twitter, rede social carro chefe da ação, foi delimitado a partir de recorte de seleção de tweets dos próprios organizadores, como forma de verificar os estímulos e respostas desses leitores, bem como o laço social (RECUERO, 2012, 2015, 2018) estabelecido entre esses indivíduos em rede e a empresa por trás da ação. Como metodologia, recorreu-se ao Estudo de Caso proposto por Yin (2015), a partir da estratégia analítica de “construção e explicação”, que prevê uma análise dos dados construindo uma explicação sobre o caso. Ao final, apresenta-se, correlativamente, tabela de estratégias comunicacionais provenientes do clube do livro analisado, amparada em uma visão holística do evento, não apenas de dados oriundos do Twitter. Um constructo que fornece uma melhor apuração das estratégias e contribui para futuras pesquisas do campo.
Collectivités territoriales et environnement - Chronique 2015
Authors: Briant Vincent de
Published: March 2021

La transition énergétique et écologique passe par les collectivités territoriales. C’est ce qu’ont montré deux lois adoptées en 2015 presque simultanément, le 7 et le 17 août. La nouvelle organisation de la République française confie en effet aux régions et aux communes une large part de la mise en oeuvre des dispositions destinées à limiter le réchauffement climatique, tout en permettant le développement durable. Un partage fonctionnel de compétences conduit en effet les régions à décliner sous forme de schémas des objectifs nationaux que les groupements de communes doivent respecter dans la délivrance de services de proximité dont ils sont chargés. Au-delà, c’est même un nouveau référentiel économique et écologique que les uns et les autres doivent promouvoir : celui de l’économie circulaire.

The authors briefly characterize the geology and structure of the Shtokovoye ore field attached to the area where the Khurchan-Orotukan zone of tectonic-magmatic activation overlays the structures of the Yana-Kolyma ore-bearing belt. Studied are mineral associations and physicochemical conditions of gold ore bodies, located both in granites and in hornfelsed sedimentary masses. By the main features of its geological structure, ore composition, and physicochemical formation conditions, the Shtokovoye ore field mineralization corresponds to the "depth" group of the gold-rare-metal formation, analogous to the Butarnoye, Basugunyinskiye, Dubach, and Nadezhda occurrences. Its ores are peculiar in the late epithermal mineralization, which is associated with the Okhotsk-Chukotka volcanic belt and overlays the sinaccretional gold-rare-metal mineralization.

Published: March 2021

Aim: determination of the influence of the technique of using balls of different weights and diameters on the level and structure of psychophysiological indicators, physical and technical fitness of football players at the initial stage of training.
Material and methods. The study was attended by 22 young footballers 10-12 years old. The subjects were divided into two groups (control and experimental) for 11 people in each. The control and experimental group trained the same amount of time for the same progips, but in the experimental group, in the main part of the class, used the technique of complex development of precision-target movements. Measured the level of physical and technical preparedness, as well as the level of psychophysiological functions of athletes.
Results. It is shown that the experimental group experienced significant improvements in the techniques of football due to the development of precision-oriented skills. Really improved results of physical and technical preparedness of athletes of the experimental group were revealed. The control group is also characterized by a significant improvement in testing results by level of technical and physical fitness, but not reliable or at a lower level of significance. The positive influence of the method of complex development of precision-target movements on the psychophysiological indices of athletes is shown. It was shown that after the experiment, the number of reliable interrelationships between the indicators of psychophysiological functions and the indicators of technical and physical fitness in the experimental group increased, and in the control remained unchanged.
Conclusions. The application of the experimental methodology for the development of precision-target movements positively influenced the level of technical and physical preparedness, psycho-physiological indicators, as well as the structure of the complex preparedness of athletes.

Published: March 2021

Purpose: to determine the effect of water plyometric training on such components of motor skills as explosive power, agility and speed in young players. Develop practical recommendations for building a training process to improve the motor skills of athletes.

Material and methods: when divided into groups of players was used a parallel randomized method with the creation of experimental and control equal groups of 20 players in each group (age 16.25 ± 1.0 years, height 168 ± 3.0 cm, body weight 61, 03 ± 4.0 kg). The duration of the experimental program was 2 months. The water plyometric training program (APT) was used in the experimental group, while the ground plyometric training program (LPT) was used in the control group.

Results. In the experimental group was found to increase the jump in height by 21.05%, long jump - by 8.84%. The experimental group also found a significant increase in dexterity by 9.35% with a significance level less than 0.05, a value of t = 7.19. Dexterity as a physical ability combines many other physical abilities, such as speed, strength, power. In the experimental group was also found a significant increase in speed by 12.50% at a significance level less than 0.05.

Conclusions. Plyometric training in the water increased the strength of the muscles of the legs of football players, while the majestic vertical jump increased by 21.05%, and the distance of the horizontal jump - by 8.84%. In addition, for 2 months, the training program contributed to the development of dexterity by 9.35% and an increase in speed by 12.50%. The use of ground plyometric training also improves physical abilities, but with fewer indicators of significant change than plyometric training in water.
Isomers of (L)-Diiodotyrosine - A DFT Treatise
Authors: Türker Lemi
Published: March 2021

(L)-Diiodotyrosine isomers are considered within the realm of density functional theory at the level of B3LYP/6-311+G(d,p). Their zwitter ionic forms are considered as well. All the structures are electronically stable, have exothermic heat of formation and favorable Gibbs free energy of formation values. Within the limitations of the method the zwitter ionic forms are not different from the corresponding parent structures in the vacuum conditions and no hydrogen bonding seems to exist between the NH2 and COOH groups. Some structural, quantum chemical and spectral data have been collected and discussed.

Authors: Berryman Zoe , Fowler Peter , Shand Michelle , Lee Martin , Williams (III) Kirk
Published: March 2021

Introduction: Orofacial clefts have a wide range of severity and can create functional and aesthetic issues for the affected individuals as well as influence their social interactions and general happiness.  Our aim was to investigate how parents/caregivers score functional and aesthetic aspects of their child’s cleft and their child’s social interactions and happiness. Method: Parents/caregivers attending the Christchurch Cleft Clinic in New Zealand between 2016 and 2019 completed a survey covering eight items—hearing, look of face, look of teeth, speech, teeth issues, food or liquid coming out of the nose, social interactions, general happiness and a free-text comment section. Items were scored using a visual analogue scale. Descriptive statistics were performed on the data and qualitative analysis of the free-text comments was conducted via thematic categorisation.Results: A total of 226 completed surveys from 154 parents were assessed. Surveys that had any incomplete question (24) and/or had repeat submissions (72) were excluded, reducing the sample to 130 surveys. ‘Speech’, ‘look of the teeth’ and ‘teeth issues’ had the lowest (worst) mean scores. Negative functional issues relating to speech and fistulas were the most common free-text themes. Conclusion: Speech was a common concern for parents, emphasising the importance of speech language therapy as a key component in cleft treatment. Parental concerns regarding the look of their child’s teeth and teeth issues highlight the need for an interdisciplinary treatment approach. The inclusion of otolaryngology and psychology services to improve issues that arise from hearing, social and emotional challenges is also recommended.
Mallet fractures: a prospective comparison of treatment outcomes
Authors: Savage Jessica A , Miller Clara , Collocott Shirley , Elliott Devlin , Smith Karen
Published: March 2021

Background: The optimal management of mallet fractures is controversial. Currently, published evidence does not clearly define the role of surgery in managing these fractures or identify when splinting alone is suitable.Methods: An observational, prospective cohort study was undertaken between 2012 and 2015 evaluating patient experience, and radiological and functional outcomes following mallet fractures managed with splinting alone or surgery combined with post-operative splinting. This study was registered with our local research facility and ethical approval was granted by the New Zealand Northern B Health and Disability Ethics Committee Health and Disability Ethics Committee (HDEC) #13/NTB/202. All patients provided formal written consent. Results: A total of 109 adult patients with 113 mallet fractures were enrolled in the study and 85 patients with 89 fractures completed follow-up. Mean follow-up was 190 days. Fractures initially associated with subluxation of the distal interphalangeal (DIP) joint treated with splinting alone were five times more likely to fail to meet a minimum standard of success than those fixed with surgery. When the fracture fragment occupies between one and two thirds of the joint surface, even in the absence of initial DIP joint subluxation, 13/35 (37%) joints subluxed during splint treatment. Conclusion: This study aids clinicians by highlighting where splinting is likely to fail and providing a means of identifying injuries in which surgery must be considered

It is not hard to list some of the profound effects COVID-19 has had on the specialty of plastic surgery. World-wide many of our colleagues have suffered serious illness and many have died. Even in countries like Australia and New Zealand, relatively spared from the ravages of the disease, we have all had significant disruptions to our lives and practicesLimitations on elective surgery during lockdown, reduced rates of screening for breast cancer and melanoma (Figure 1), consulting with masks—all affect our ability to provide a safe and effective service for our patients. Eminent plastic surgeons choosing to take early retirement is a great loss of institutional memory. Opportunistic governments and administrators taking advantage and using COVID-19 as an excuse to push through ‘urgent’ changes challenge our ability to provide a safe and effective service
Innovation in rural workforce strategies by a national surgical society
Authors: Bryant Keith , Dean Nicola R
Published: March 2021

Health services exist to address the health needs of the community. But in Australia at present there are not enough detailed data to tell us to what extent, community by community, our highly regarded health system is meeting those needs. We know that demand for health care services is growing faster than the overall economy, and that we no longer have a general shortage of doctors, but most problematically there is a significant geographic maldistribution of those doctors away from rural and regional areas.iFor plastic surgery services, there is very little understanding of what the aggregate needs of rural communities are, or how these needs vary by community. We know by anecdote that there is significant inequity in plastic surgery services and that rural and regional locations often have unfilled positions and diminished services. We note that 80 per cent of specialist plastic surgeons live and work wholly within the five largest Modified Monash level 1 (MM1) Australian cities.1 Only 8.5 per cent of specialist plastic surgeons are permanently based outside those five cities. We also note that this is a more serious negative divergence than other comparable surgical specialties.While we briefly explore the basis for some ‘innovative’ solutions in this paper, we are constantly reminded that a prerequisite of any ‘solution’ should be an in-depth study of what Australian rural communities need or want in terms of plastic surgery services.

Published: March 2021

Indonesia is a densely populated country with a population of 260 million, making Indonesia the fourth most populous country in the world. The continued rapid development of the economy in Indonesia has made land an asset that provides benefits. In Indonesia, land ownership that has the highest legal power is proven by a Certificate of Ownership or in indonesian is called as Sertifikat Hak Milik (SHM). Meanwhile, the land titling process is often complex and lengthy, and because of the processing carried out by government agencies in handling a variety of different documents, some structured people commit fraud. The impact is that the model currently used does not have good governance. This research offers a Blockchain-based solution in providing data harmony and openness, lightening in data access, permanent records management, and most importantly it is a solution that is cheaper and faster. This research offers a step-by-step model of Blockchain selection beginning from the public Blockchain ledger which will continuously incorporate two degrees of Hybrid Blockchain. The smart contract design of the Public Blockchain is provided in detail as well as the use of Ethereum in implementing its prototype system. In the experimental test using the local Ethereum test network directly to show the effectiveness of the system. The results of the analysis show that the model offered can reduce the costs required for processing information, the number of trips required, and result in easy access to important information. With the implementation of Blockchain, efforts to digitize land rights in Indonesia can increase.
Trends in global inequality using a new integrated dataset
Authors: Gradín Carlos
Published: March 2021

This paper presents preliminary evidence of the annual global income distribution since 1950 using a new integrated dataset that aggregates standardized country income distributions at the percentile level estimated from various sources in the World Income Inequality Database.

I analyse the extent to which the main global inequality trends depend on specific distributive views, i.e. absolute or relative, or with more emphasis in specific parts of the distribution. The results show absolute inequality increasing almost continuously. Relative inequality has been clearly reduced in the long term but with most indices also showing a sharp decline since at least end of 1990s due to income differences between countries being narrowed.

I also quantify the contribution of different countries and regions through changes in average income, in inequality or in population, showing that the main global trends are largely driven by the drastic changes experienced by China and India over these decade.

Comparison of maximum likelihood estimators and regression models for burn severity mapping in Mediterranean forests using Landsat TM and ETM+ data
Authors: Ariza Alexander , Salas Rey Javier , Merino de Miguel Silvia
Published: March 2021

Durante la última década, ha habido un número creciente de trabajos publicados sobre la gravedad de los incendios forestales utilizando datos de teledetección para fines de gestión de recursos naturales y de investigación. Muchos de estos estudios cuantifican los cambios entre las condiciones de vegetación antes y después del incendio a partir de imágenes satelitales utilizando índices espectrales; sin embargo, hay una discusión activa sobre cuál de los índices más comúnmente usados es más adecuado para estimar la severidad de la quemadura, y qué metodología es la mejor para la estimación de los niveles de severidad. Este estudio propone y evalúa un algoritmo de aprendizaje automático de Estimación de Máxima Verosimilitud (EMV) para mapear la severidad de las quemaduras como una alternativa a los modelos de regresión.Desarrollamos ambos métodos usando datos de campo de GeoCBI (Índice Compuesto de Quema Geométricamente Estructurado, siglas en inglés) y seis índices espectrales diferentes (derivados de imágenes Landsat TM y ETM+) para dos incendios forestales en el centro de España. Comparamos la capacidad para discriminar la severidad de la quemadura de estos índices a través de un índice de separabilidad espectral (M), y evaluamos su concordancia con datos de campo basados en GeoCBI usando el coeficiente de determinación (R2). Posteriormente, el índice seleccionado se utilizó para los modelos de regresión y la EMV para estimar los niveles de severidad de quema (sin quemar, bajo, moderado y alto), y se validó con datos de campo. El índice RBR mostró una mejor separabilidad espectral (promedio entre dos fuegos M= 2.00) que el dNBR (M= 1.82) y RdNBR (M= 1.80). Además, GeoCBI tuvo un mayor ajuste con RBR (R2= 0.73) que con RdNBR (R2= 0.72) y dNBR (R2= 0.71).Finalmente, la EMV mostró la mayor precisión de clasificación general (Kappa=0,65) y la mejor precisión para cada clase individual.
Estudio de susceptibilidad a procesos de remoción en masa. Caso de estudio: Zona centro del Estado de Guerrero, México, mediante herramientas geotecnológicas
Authors: Romero-Rojas Wendy , Vázquez-Jiménez René , Ramos-Bernal Rocío N.
Published: March 2021

Los procesos de remoción en masa constituyen procesos geológicos recurrentes y representan una amenaza latente en el Estado de Guerrero, por su vínculo con eventos hidrometeorológicos extraordinarios. En varios estudios que caracterizan estos procesos, se aplican técnicas de percepción remota y la información se integra a través de los Sistemas de Información Geográfica. El modelo de susceptibilidad a procesos de remoción en masa, incluyó la interpretación de factores físicos que intervienen en dichos procesos, los cuales fueron caracterizados por distintos mapas temáticos. La generación final del modelo consistió en la acumulación final de los aportes individuales de cada factor (Recondo, 2000; Hervas y Barredo, 2001; Hervas, et al., 2002), el cual representó una zonificación por índice de susceptibilidad; la corroboración de los datos se realizó a través de un inventario de deslizamientos, generado a través de interpretación de imágenes online, aplicando las herramientas de Google Earth. Los resultados indican que el modelo de susceptibilidad a procesos de remoción en masa, permite identificar y categorizar efectivamente las zonas de riesgo, además se determinó que los factores litológicos, estructurales, topográficos y los eventos hidrometeorológicos de septiembre de 2013, fueron los que provocaron la incidencia de la mayoría de los deslizamientos registrados.

Published: March 2021

En los últimos años, la incidencia de ataques por cocodrilos en Costa Rica, se han incrementado, lo cual está asociado al desarrollo de las actividades humanas en áreas consideradas como óptimas en lo que determinó como hábitat potencial de la especie. Dado lo anterior, la presente investigación plantea la identificación de zonas de interacción entre el cocodrilo y el ser humano a partir de la integración de variables físico-geográficas por medio de los Sistemas de Información Geográfica (SIG). De esta manera, se realizó una recopilación teórica para la identificación de las variables físico-geográficas que integran el hábitat del cocodrilo (pendiente, red de drenaje, áreas de inundación y coberturas de uso de la tierra), así como las variables socioambientales que influyen en la alteración y la pérdida del hábitat de la especie (cantidad de poblados, densidad de población, densidad de caminos, y coberturas de uso de la tierra). Así mismo, se integraron los registros de casos con cocodrilos atendidos por el cuerpo de bomberos. Se logró evidenciar que la mayoría de incidentes se presentan en zonas con una alta interacción (áreas adonde se realizan una amplia varie-dad de actividades antrópicas), dentro del hábitat potencial de este reptil. Adicionalmente, los resultados obtenidos en la investigación constituyen un insumo importante en la toma de decisiones a nivel de política y ordenamiento territorial en la Región Pacífico Central, ya que en esta zona el turismo es una de las principales actividades económicas que puede llegar a ser amenazada por un ataque de ésta especie.

Published: March 2021

This paper presents the development of individual contributions, in the generation of irreversibilities, of a refrigeration system based on the Coefficient of Operation (COP). The generation of irreversibilities has been widely analyzed using the principles of the first and second laws of thermodynamics. This analysis uses the parameters of enthalpy, entropy as well as the temperature and heat generated in each component. The method proposed in this work improves the accuracy of the calculations due to the use of the COP in the mathematical process, which includes the processes of heat transfer and pressure drops developed in the evaporator, suction line, compressor, discharge line, condenser, liquid line and expansion valve of the mechanical vapor compression refrigeration system. The mathematical analyzes and the experimental results are shown, with these it is concluded that the exposed procedure is closer to the real conditions than those traditional procedures found in the text books.

Published: March 2021

This study was motivated by the fact that space industry has become one of the most innovative, rapidly developing, least crisis-sensitive industries, which grows dynamically worldwide. Its resilience to shocks is quite apparent. Since the outbreak of the pandemic1 in spring 2020, the sector preserved many jobs and created new ones, while its innovative and technological advances remained uninterrupted. This study – based on surveys, statistical and other databases – aims to take stock of the current state of the Hungarian space sector and industry, and to set out possible directions for state involvement to enhance further progress. Our research confirmed that the Hungarian space industry, although its direct contribution to social performance is moderate today, employs a significant number of highly skilled workers and introduces cuttingedge technologies. Furthermore, through its innovations and technological and scientific transfers, its contribution to the competitiveness of the Hungarian economy is significant, even at the current level of its capacities. With adequate support and wise investments, the added value, the growth and international potential and the global space industry value chain involvement the space industry can be exploited to a much greater extent than at present.

The merits and functions of mantras are frequently debated nowadays. If we glance at the history of the creation of mantras and their roles in the life of the Malay society, mantras are undoubtedly countless in number. They became instruments for medicine, self-defense, beauty, and other areas as well. The objective of this paper is to identify and elaborate the symbols and meanings of the elements of nature used in mantras. This research uses Peirce Theory of Semiotics for the descriptive analysis of the document. In mantras, the practitioner frequently uses elements of the symbols of nature as representations, such as mountains and oceans, depending on the form of mantra used. If mantras are used to beautify oneself or as a love charm, usually beautiful and pleasant elements will be chanted, for example, the moon, sun, stars, and others. Hence, through the use of mantras, the elements of the symbol found in them contain the value of the Malay mind that is seen to give an identity or an actual description of the life of the Malay society in the past. Mantras are seen as very important in society’s social system in the past.
SOURCE IN THE NATIONAL ARCHIVES OF MALAYSIA RELATING TO THE ADMINISTRATION OF BRITISH MALAYA IN BETWEEN 1786-1957

Published: March 2021

This paper aims at the archival sources from the interval the British administered Malaya ranging from the year 1786 to 1957 kept in the National Archives of Malaysia (NAM). The British Administration records were the biggest and virtually complete collection found in NAM and the most popular among researchers who perform the study relating to social, economic, and political in Malaya from the 18th to 20th century. These records shrouded vast of major historical events that happen in Malaya either before and after independence. During the British Malaya epoch, there are as many as 958 sets of record groups containing as many as 714,634 files and 3,652,691 pieces of attachments preserved in NAM. The purpose of this paper is to discuss the record groups and record descriptions, namely the Selangor State Secretary, the Federal Secretariat, the High Commissioner Office, the Malayan Union, and the British Military Administration. These groups are collections of prime records that shaped the country during the existence of the British administration in Malaya. All metadata of these record groups have been included in the COMPASS System (Computerized Archival System and Services). Although there are various other materials in NAM such as materials during the Portuguese, Dutch, and even Japanese invasions, due to the relatively small amount of material added with language constraints make the materials at that timeless popular among researchers, especially the local researchers.
CHINA'S FOREIGN POLICY TOWARDS MYANMAR: A ROLE MODEL IN INTERNATIONAL RELATIONS
Authors: Zreik Mohamad
Published: March 2021

China has a large and professional diplomatic team spread all over the world. Chinese diplomacy mainly relies on soft power in its relations with international partners. Despite the unified outlines, Chinese foreign policy differs from one country to another, depending on the geographical location, the political system and the volume of trade exchange. Chinese foreign policy has gone through many stages, most notably the period of Mao Zedong who strictly applied the rules of socialism, and the period of Deng Xiaoping, known for its reform and openness policy, thus establishing a modern and more flexible Chinese system.

President Xi Jinping's term is an extension of Deng Xiaoping's rule of thumb, but with more openness to international partners and economic expansion, especially with the launch of the Belt and Road Initiative in 2013. This paper deals with China's foreign policy towards Myanmar, and refers to the development of bilateral relations and China's interest in a distinguished relationship with Myanmar. The research indicates the strategic factors that make China interested in developing the relationship with Myanmar.

Genetic divergence analysis in basmati rice genotypes (Oryza sativa L.) for agro-morphological and quality traits using multivariate approach
Authors: Kumar Vinod , Singh Dhirendra
Published: March 2021

Genetic diversity of 30 basmati rice genotypes was analysed based on nine agro-morphological and six quality traits. The results of the principal component analysis showed that the first six principal components explained 89.16% of the total variation in the experimental material. These 30 basmati genotypes were grouped into six clusters which indicated the presence of sufficient diversity among the tested genotypes. Cluster I and cluster III was found to be the largest comprising of 10 genotypes each followed by cluster II having seven genotypes. The highest average intra-cluster distance was observed in cluster III. Highest inter-cluster distance (D2) was observed between clusters III and VI followed by clusters III and V, III and IV & clusters II and III. Cluster II showed high mean value for grain yield per plant, 1000 grain weight, and grain length. The characters viz., amylose content, grain length after cooking, spikelet per panicle, grain width, grain length and 1000 grain weight contributed maximum towards total genetic divergence, suggest their suitability of selection.

POLYPARAMETRIC BLOCK CODING
Authors: Milova Julia , Melnik Yuri
Published: March 2021

The principles of poly-parametric information coding have been considered. The methods for developing poly-parametric codes have been presented. It is shown that the protection of block codes from channel interference using check patterns can be developed by a mono- or poly-parametric method. A special type of block codes has been presented, the check patterns of which are formed on the basis of their neighbours, which are functionally related to the given code combination. Such codes have been called poly-parametric. Binary poly-parametric ring codes, the check patterns of which are designed to detect and correct channel errors, are developed using the properties of Galois fields and on the basis of the vector shift indicators of the codewords. To obtain digital poly-parametric block codes, the properties and features of the normalized natural sequence are used. It is shown that each codeword of a binary block code can be represented as a certain positive integer in the decimal number system, which is an element of the natural sequence. Its elements on an interval that equals the norm acquire a functional dependency.

Background: Many different methods are applied for radon mapping depending on the purpose of the map and the data that are available. In addition, the definitions of radon priority areas (RPA) in EU Member States, as requested in the new European EURATOM BSS (1), are diverse.

Objective: 1) Comparison of methods for mapping geogenic and indoor radon, 2) the possible transferability of a mapping method developed in one region to other regions and 3) the evaluation of the impact of different mapping methods on the delineation of RPAs.

Design: Different mapping methods and several RPA definitions were applied to the same data sets from six municipalities in Austria and Cantabria, Spain.

Results: Some mapping methods revealed a satisfying degree of agreement, but relevant differences were also observed. The chosen threshold for RPA classification has a major impact, depending on the level of radon concentration in the area. The resulting maps were compared regarding the spatial estimates and the delineation of RPAs.

Conclusions: Not every mapping method is suitable for every available data set. Data robustness and harmonisation are the main requirements, especially if the used data set is not designed for a specific technique. Different mapping methods often deliver similar results in RPA classification. The definition of thresholds for the classification and delineation of RPAs is a guidance factor in the mapping process and is as relevant as harmonising mapping methods depending on the radon levels in the area.

Published: March 2021

Al/Ni multilayer film shows a self-propagating exothermic reaction when a minute external shock is applied. Using the reactive film as a heat source for soldering enables us to complete the bonding process instantaneously within a second because of its fast reaction propagation. However, cracks are introduced in the reacted NiAl layer after bonding, which becomes a big problem in the viewpoint of thermal and mechanical reliability. In this study, a laser-induced multiple points ignition technique is developed, and reaction propagation characteristics and crack introducing phenomenon are investigated toward crack propagation control.
