Trends of industry-leading biotechnology stocks during COVID-19
Authors: Zhang Navia , Haskins Meredith
Published: November 2021

The 2019-nCoV coronavirus has significantly impacted the macroeconomic outlook for countries across the world. The biotechnology sector experienced a relatively positive stock price outlook, which corroborates the trends exhibited by biotechnology stocks in previous pandemics such as SARS (2003) and AH1N1 (2009). During the COVID-19 pandemic, vaccine roll-out rates have been more efficient than in any other pandemic, as companies today are more experienced in combating the time constraint to create vaccines. Gilead Sciences Inc. saw its shares rise 18% after developing the first FDA-approved COVID-19 vaccine, 'remdesivir'. In contrast, AstraZeneca's shares fell 2.28% in 2021 after its vaccine underwent investigations into blood-clotting side effects and subsequent suspension from several countries. Companies developing mRNA vaccines like Moderna, BioNTech, and Pfizer witnessed surges in share prices ranging from 10% to 20%. Many newer biotech companies such as Genexie, Sanovi, OnoSec, and Vaxart have also developed vaccines for COVID-19. Share prices are more volatile for these less established companies. This paper observes how developing new technologies, staging clinical trials, obtaining FDA approvals, gaining publicity, and several other complex factors have profound impacts on the stock prices of these biotechnology companies.
The Rise in Household Liquidity
Authors:   Reserve Bank of Australia, La Cava Gianni , Wang Lydia ,   Reserve Bank of Australia
Published: November 2021

It is well documented that household wealth has risen significantly in recent decades and that both sides of the household balance sheet – assets and liabilities – have expanded. We document a less well-known phenomenon: household liquid assets (such as cash, deposits and equities) have also risen strongly relative to income over the same period. This is true for Australia and for most advanced economies. We explore the determinants of liquidity across households and over time, using a range of household surveys for Australia. We find that household liquidity is strongly associated with life cycle factors, such as age and housing tenure. The increase in liquidity over recent decades has been broad based across households, though strongest amongst those with mortgage debt. Consistent with this, the share of liquidity-constrained households has declined significantly. The growth in liquidity is closely connected to developments in the housing market. First, higher housing prices have lifted the deposit requirement for potential home buyers, encouraging such households to save more in liquid assets. Second, higher mortgage debt has increased the repayment risks associated with future income declines, leading indebted home owners to save more for precautionary reasons, partly through paying down debt ahead of schedule. The process of building wealth and liquidity through debt amortisation has been supported by the trend decline in interest rates and unique financial innovations such as mortgage offset and redraw accounts that have made housing wealth more liquid. Overall, the rise in household liquidity appears to have increased the financial resilience of the household sector.
Oil exploration and discovery in the basement rocks of Bach Ho field: Documentation, facts and lessons
Authors: Tran Van Hoi , Nguyen Van Duc , Pham Xuan Son
Published: November 2021

During the 40 years of operation and development (1981 - 2021), the Vietnam - Russia Joint Venture "Vietsovpetro" has witnessed many historical milestones, but the discovery of industrial oil for the first time from the fractured and weathered granite basement at exploration well BH-6 on 11 May 1987 is the most important one.

From the first oil in the basement rock of Bach Ho field, Vietsovpetro consecutively discovered industrial oil in other fields in its area of operation, such as Dong Bac Rong (1991), Dong Nam Rong (1995), Nam Rong (2005), Nam Trung Tam Rong (2006), etc. At the beginning of 2018, the 2P (P1+P2) oil reserve from the basement rock accounted for 74% of Vietsovpetro's total balanced reserves at that time. As of 1 October 2021, the total oil produced from the basement reached 235 million m3 (195 million tons), accounting for 86% of Vietsovpetro's total oil output.

Being encouraged by the success and experience of Vietsovpetro, other domestic and foreign oil and gas companies (PVEP, JVPC, Talisman, and Petronas, etc.) have explored and discovered oil and gas from the granite basement and put the fields of Rang Dong, Su Tu Den, Hong Ngoc, and Hai Su Den, etc. into operation. This fact has, at the same time, created a strong attraction for domestic and foreign investors, making important contributions to the rapid development of Vietnam's oil and gas industry which was still very young at the time.

The above-mentioned shows that it is time to study data and documents, draw lessons from success and failure gained during the 40 years of basement exploration. The outcomes should be used as a basis to formulate an appropriate exploration strategy for Vietsovpetro in the coming decades with strong fluctuations in the oil and gas market expected, and the inevitable depletion of non-renewable resources worldwide.
The Role of ‘Ulama (Arabic Scholars) In The 19th Century Yoruba Nation And Politics
Authors: Hashimi A. O.
Published: November 2021

The nineteenth Century was a revolutionary period in the history of societies, kingdoms and empires in Yorubaland. The Century witnessed profound and irreversible social, religious and political transformations in the lives of the people who lived in the region. Both internal and external factors were responsible for these processes of change. The consequential events centred on commerce, politics, religion, warfare, intra-and intergroup relations, and reform and adjustment to new ways of life. This paper describes the activities of the Muslims in the 19th century Yoruba Politics, and the significant roles played by the ‘Ulama in the period under study. Islam was introduced to Yorubaland before the 19th century, and the population was reinforced by the ingress of Muslim immigrants and Hausa slaves who were brought to Oyo Empire. In this diverse group different roles were played by the Muslim community and the ‘Ulama (clerics). The activities of the Muslims had momentous impact on 19th century Yoruba politics in different ways as recorded in Arabic documents and other historical materials. In the course of time, Muslims occupied positions of great authority in royal administration. They used their position to promote Islam. This paper argues that the roles of the ‘Ulama in the political transformation and social change in Yorubaland was so important that its impact is felt till today.
Unintended Meanings In Christian Faith-Based Discourse
Authors: Olayemi Oluwakemi Titilola
Published: November 2021

Language, in different facets of human life, has always enjoyed the attention of scholars over the years. There have been works on Christian faith-based discourse, some of which are termed ‘the language of religion’, ‘religious language’, ‘Christian religious language’, ‘language of worship’, etc. most of these works focus on register or vocabulary. With the proliferation of churches in Nigeria today, certain linguistic trends have emerged in Christian faith-based discourse. This paper investigates these linguistic trends in Christian assemblies with the aim of highlighting the meanings they could convey. Fifteen speech samples produced by a set of purposively sampled participants who occupy certain leadership positions in their assemblies are used in this study. Some of the speech samples were transcribed from existing audio-tapes and interaction with church leaders while others were recorded through note-taking during church activities. The findings reveal that the trend of language usage under study projectsunpleasant and unintended meanings which may inhibit the successful practice of the Christian faith by adherents, and hinder intending or prospective members. Unintended expressions tend to underrate God and magnify Satan (the archenemy of the Christians), or they mock the Christian faith and exaggerate life’s problems. Words are powerful and as such, must be employed in Christian faith-based discourses with utmost care. The role of language in the progress of the church, physically or spiritually, should not be underestimated.
As políticas públicas de formação inovadoras no norte de Mato Grosso/Mt, Brasil
Authors: Roque-Faria Helenice Joviano , Aparecido da Silva Kleber
Published: November 2021

O artigo discute as inovações propostas nas políticas públicas formativas implantadas no Brasil, especialmente, em contexto norte do estado de Mato Grosso (MT) e analisa as ações formativas para professores atuantes na área de Língua Portuguesa. Defendemos a tese de que, embora os empreendimentos propositivos de formação tenham alcance significativo na atualidade, insta refletir sobre novos modos para atuar junto às demandas educativas. Atentos ao mundo contemporâneo e conscientes de que a solidez se transforma em liquidez, reconhecemos, que o futuro professor e aqueles em atuação devem irromper as barreiras hegemônicas educacionais, construir sua identidade com protagonismo e criticidade e intervir nas práticas situadas de linguagem. Nesse sentido, o respaldo metodológico fixa nos estudos qualitativo-interpretativistas e para tal recortamos do documento que direciona a Política Educacional do Estado de Mato Grosso, a Portaria Normativa n. 17, de 28 de dezembro de 2009, a qual dispõe sobre o Programa de Formação Nacional em Rede e a Portaria 46, de 11 de abril de 2016 e regulamenta o Programa Institucional de Bolsa de Iniciação à Docência (PIBID – Língua Portuguesa) e propomos algumas questões: a) De que forma as políticas formativas interferem/contribuem para o desenvolvimento profissional docente? Pautados na Linguística Aplicada Crítica construímos algumas asseverações, dentre elas, que as ações implementadas – e que se quer permanentes – demandam maior integração e investimento público.
Violencia, diálogo y aprendizaje de la filosofía: intervención docente en el nivel medio superior
Authors: Piña Arellano Luis Eduardo , Mireles Vargas Olivia
Published: November 2021

El objetivo de este trabajo es exponer los resultados de una intervención docente diseñada para la enseñanza de la filosofía en el nivel medio superior (secundaria del segundo ciclo). Aquí se sostiene que el problema social de la violencia y el conflicto puede ser aminorado si se educa a las nuevas generaciones para el diálogo, y más aún para el diálogo filosófico. A partir de este supuesto se diseñó y se puso en marcha una propuesta didáctica basada en el aprendizaje colaborativo y en un concepto de diálogo entendido como un intercambio argumentativo entre los participantes, orientado a una meta para la construcción colectiva de sentido. Se expone de manera general el problema que se avizora en la sociedad contemporánea, para después explicar los principios teóricos que se adoptaron para la planeación didáctica, finalmente se dan a conocer los resultados de la experiencia que se llevó a cabo a través de recursos digitales en el contexto de la pandemia por Covid-19. Se observa que a pesar de los límites que impone la educación a través de la pantalla, el estudiantado se apropia de los contenidos filosóficos, y además pone en juego sus habilidades para dialogar, argumentar y construir en común.
Enseñar Historia en tiempos de emergencia sanitaria
Authors: Falconer Marianel , Sánchez Celina
Published: November 2021

La irrupción en la vida cotidiana del COVID-19 modificó sustancialmente la vida de las personas, y la escuela no ha sido ajena. Las instituciones escolares se encontraron ante una situación inédita que implicó la toma de decisiones rápidas y la modificación de estas en el día a día. Así, el aprendizaje de las y los estudiantes se vio totalmente trastocado y por lo tanto también las formas de enseñanza.
Aquí buscamos reflexionar en torno de nuestras experiencias particulares en el año lectivo de pandemia que acaba de pasar a través de las problemáticas más significativas. Donde entendemos que la transformación del aula de un espacio físico a uno virtual generó el desafío a la hora de enseñar Historia y generar aprendizajes significativos cuando la vida de las y los estudiantes estaba centrada en otras preocupaciones.
El objetivo que guía este trabajo es articular nuestras experiencias como docentes del Nivel Medio en torno a la virtualidad durante el año 2020 y otorgar un marco teórico a nuestra práctica desde una mirada cualitativa.
estructura digital accesible es un derecho humano de las personas con discapacidad visual
Authors: Libiert Frost Nájera Claudia
Published: November 2021

La educación en línea forzada por la pandemia del 2020, puede ser un trampolín de oportunidades para la inclusión de personas con discapacidad visual gracias a las tecnologías de asistencia; o bien, las puede dejar fuera por el analfabetismo que existe en la sociedad con respecto a dónde encontrar y cómo usar dichas tecnologías de asistencia para favorecer la inclusión de este colectivo. Por ello, es de vital importancia implementar tecnologías de asistencia y metodologías didácticas innovadoras, que permitan aprendizajes significativos y generen motivación en los estudiantes con discapacidad visual para participar de manera más proactiva. El juego y la formación aleatoria de equipos que permiten las plataformas potencializa la capacidad adaptativa de estos estudiantes en la comunidad educativa, al tiempo que se ejerce el derecho a la accesibilidad mediante la información en múltiples formatos de diseño universal para el aprendizaje. En este ensayo la autora, quien conduce una sala tiflotécnica en una universidad politécnica, discute el tipo de tecnologías digitales que coadyuvan a eliminar barreras al aprendizaje de personas con discapacidad visual, colectivo al que ella misma pertenece, con el propósito que se puedan generar el tipo de escenarios educativos que requieren.
La mesa (red) de cine social y comunitario de Córdoba en la praxis de la pedagogía decolonial
Authors: Grosman Carla
Published: November 2021

Este artículo asocia la actividad tallerística de varios grupos contemporáneos de cine comunitario cordobés a una dinámica de legitimación de la “pedagogía decolonial” (C. Walsh, 2013). Entiendo esta última como praxis de un “dispositivo” (Foucault, 1980, [1977]) que identifico como el dispositivo decolonial pues sus relaciones de saber/poder son una práctica contra-hegemónica dentro de las dinámicas onto-epistemológicas de reproducción de aquello que Aníbal Quijano (2000) llamó “Colonialidad del poder” ( y que desde un análisis Foucaultiano del discurso leo como “dispositivo de poder”). El artículo observa como el cine comunitario sigue los dos estadios propuestos por la pedagogía decolonial como pasos ineludibles hacia la emancipación de los sujetos subalternos. 1- la puesta en crisis de los saberes y las identidades hegemónicas, lo que se logra desde la identificación critica de su situación histórica y el aprendizaje de los artificios del lenguaje audiovisual en tanto aparato de reproducción ideológica colonial-capitalista (enfrentando la colonialidad del ser). 2- Una propuesta teleológica por una vida decolonializada que emerge tanto de la apropiación tecnológica del lenguaje audiovisual desde el cual realizan su narración, su film, como también de las relaciones sociales “Otras” de producción de su mensaje (enfrentando la colonialidad del saber).
Urbanismo proempresarial y viviendas desocupadas en el área metropolitana de Buenos Aires: el caso de la ciudad de Lomas de Zamora
Authors: Romano Bárbara Teresa
Published: November 2021

El proceso de recuperación económica que se vivenció luego de la crisis económica, social y política del año 2001 en la Argentina, representó una oportunidad, fundamentalmente, para el sector de la construcción y de los negocios inmobiliarios.Las inversiones de los promotores inmobiliarios, amparados por los mismos gobiernos locales, se concentraron no solamente en los tradicionales barrios de la Ciudad Autónoma de Buenos Aires, sino también en zonas poco exploradas por el urbanismo proempresarial: las localidades cabeceras de los partidos del Área Metropolitana de Buenos Aires (AMBA). Una de ellas es Lomas de Zamora, que se ubica en el corredor sur del aglomerado, y ha experimentado un reciente proceso de verticalización que hacontribuido a la expansión de las viviendas desocupadas. En esta presentación, nos proponemos analizar la cantidad y distribución de viviendas desocupadas, a través de la información presente en los tres últimos censos nacionales de población, hogares yviviendas (INDEC, 1991 – 2001- 2010), en contraposición al crecimiento de la población residencial que parece estancado; con un enfoque que pretende interpretar las características que están por detrás del fenómeno (¿o estrategia inmobiliaria?) de lasviviendas desocupadas.

Authors: N Manjunatha
Published: November 2021

Every manufacturing firm formulates one or the other marketing strategies to capture more market share and revenue. Managers of each firm irrespective of the type of business make export policies to keep competitors away in international markets. The success of a firm’s export performance lies in the positive influence of internal and external factors. The objective of the research study is to explore the relationship between a firm’s internal factors such as firm’s, managerial and product characteristics on export marketing strategy standardisation in the auto component manufacturing industry specially those firms locating in southern parts of India. Descriptive research methodology has been applied for analysing the data. The linear regression model has been used in the present study and tested the significant association among the variables related to internal forces and standardisation of export marketing strategies. The finding shows that, export marketing capabilities, managers export commitment, product characteristics have a significant relationship with product standardisation. Export marketing capabilities, managers export commitment, managers export motivation have positive influence on price standardisation similarly, export marketing capabilities, managers export commitment have significant relationship with distribution standardization. Similarly, firm’s internationalisation capabilities manager’s export commitment and managers export knowledge and product characteristics have significant impact on promotion standardisation. This research article is confined to the auto component industry which is engaged in export activities and limited to the statndardisation of marketing strategies in international business.

CAFTA-DR, importaciones de granos básicos y la destrucción de la agricultura salvadoreña
Authors: Cáceres Araniva Luis René
Published: November 2021

Este trabajo presenta argumentos que defienden que no es conveniente para nuestro país poner en vigor la cláusula establecida en el tratado del CAFTA-DR sobre la importación de maíz y maicillo libres de impuestos. Se insiste en que la agricultura nacional, lo mismo que el sector manufacturero, ha sufrido severas contracciones desde los años noventa y una medida de esa naturaleza podría dar un golpe terminal al sector, con consecuencias en términos de aumentos de desempleo, violencia, inseguridad alimentaria y emigración regular. El trabajo presenta datos que permiten apreciar la contracción de los sectores productivos a raíz del crecimiento desmedido de las importaciones resultantes de la reducción de la tarifa a las importaciones, situación que se agravaría si la cláusula en cuestión entrara en vigor. La recomendación es que se negocie con los EE. UU. que esa cláusula se deje sin efecto. En los anexos, se presentan propuestas relacionadas con inversiones en el sector agropecuario, con el apoyo a la caficultura nacional mediante la emisión de una moneda electrónica y sobre el diseño de un portal electrónico para la venta de café en el mercado nacional e internacional.

A semiotic investigation of the graphic imagery by pioneer tattoo artists in KwaZulu-Natal with special reference to the Ramesar brothers
Authors:   , Van As Rory
Published: November 2021

This study focuses on the graphic imagery of tattoo artists in KwaZulu-­‐Natal with special reference to the Ramesar brothers. Various visual communication practices and theories are drawn upon to explain the imagery created by them. The literature review chapters of this study cover a brief history of primarily Western tattooing practices, as well as a discussion of the meaning of tattoos from a visual semiotics perspective. The fieldwork component of the study involved conducting and analysing a series of qualitative in-­‐depth interviews with interviewees who were either tattooed by, or are family members of, the Ramesar brothers. The purpose of the interviews was to explore the personal experiences and motivations that contributed to the work of these tattoo artists. The study contributes to visual studies in South Africa in the sense that the empirical data confirm the pioneer status of the Ramesar brothers as graphic artists.

Effect of substituting maize grain with cobs treated with combinations of urea and wood ash on chemical composition and in sacco degradability
Authors: Abdulazeez A. , Madibela O. R. , Tsopito C. M.
Published: November 2021

An experiment was conducted to determine the effect of substituting maize grain with maize cobs treated with 25% urea (U) plus 75% wood ash (WA) on chemical composition and in sacco degradability. Maize grain was substituted with graded levels of 25U75WA in the dietary ingredients and the treatments were: 100M = 100% maize grain, 66M34C = 66% maize grain plus 34% treated maize cobs, 34M66C = 34% maize grain plus 66% treated maize cobs and 100C = 100% treated maize cobs. Samples were analyzed for dry matter (DM), organic matter (OM), ash, crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL); they were incubated in saccofor 6, 12, 24, 48 and 72 hrs and their DM degradation kinetics described using the equation y = a + b ct (1- e- ). Results indicated that as maize grain is substituted with treated maize cobs, NDF, ADF and ADL also increased, however only the neutral detergent soluble (NDS) for treatment 100C was reduced. At 72 hrs of incubation, treatment 34M66C had the highest DM degradation, rapidly soluble fraction 'a' and potential degradability 'a+b'. It was concluded that maize cobs treated with combinations of urea and WA could substitute 66% of maize grain in sheep diets.

 

 

Une expérience a été menée pour déterminer l'effet de la substitution du grain de maïs par des épis de maïs traités avec 25 % d'urée (U) plus 75 % de cendre de bois (WA) sur la composition chimique et la dégradabilité du sac. Le grain de maïs a été remplacé par des niveaux gradués de 25U75WA dans les ingrédients alimentaires et les traitements étaient : et 100C = 100 % d'épis de maïs traités. Les échantillons ont été analysés pour la matière sèche (MS), la matière organique (MO), les cendres, les protéines brutes (CP), les fibres au détergent neutre (NDF), les fibres au détergent acide (ADF) et la lignine au détergent acide (ADL) ; ils ont été incubés dans sacco pour 6, 12, 24, 48 et 72 heures et leur cinétique de dégradation de la matière sèche décrite en utilisant l'équation y = a + b (1-e-ct). Les résultats ont indiqué que lorsque le grain de maïs est remplacé par des épis de maïs traités, NDF, ADF et ADL ont également augmenté, mais que seul le détergent neutre soluble (NDS) pour le traitement 100C a été réduit. À 72 heures d'incubation, le traitement 34M66C présentait la plus forte dégradation de MS, la fraction rapidement soluble « a » et la dégradabilité potentielle « a+b ». Il a été conclu que les épis de maïs traités avec des combinaisons d'urée et d'AO pouvaient remplacer 66% des grains de maïs dans l'alimentation des moutons.

EL ESQUIROLAJE EN LA EMPRESA DEL SIGLO XXI. REPASO JURISPRUDENCIAL DEL CASO ESPAÑOL
Authors: Ruiz Saura José Enrique
Published: November 2021

En las últimas décadas, la doctrina científica y jurisprudencial ha ido concretando los límites legales de las nuevas prácticas empresariales dirigidas a anular los efectos del ejercicio de la huelga, todas ellas comprendidas en el concepto de esquirolaje. Dado que la actual regulación de este derecho fundamental es escasa y data del año 1977, para poder determinar con precisión el criterio judicial aplicable ante realidades laborales novedosas, ha de estudiarse minuciosamente la evolución y la consolidación de la jurisprudencia acaecida a raíz de la entrada en el escenario laboral de fenómenos como la externalización de servicios, la automatización de procesos o la gestión algorítmica de los recursos humanos. Consecuentemente, en este trabajo se ha procedido a la recopilación y análisis exhaustivo de las resoluciones más relevantes que el Tribunal Constitucional, el Tribunal Supremo y distintos Tribunales Superiores de Justicia han emitido en los últimos años. De ello, puede extraerse que los tribunales han pasado de censurar únicamente la sustitución de huelguistas por trabajadores ajenos a la empresa (esquirolaje externo) a declarar contrarios a Derecho otros tipos no recogidos expresamente en la norma, como es la sustitución de huelguistas por trabajadores pertenecientes a empresas contratistas, más recientemente, sustituir la labor de los trabajadores ausentes mediante el empleo de instrumentos tecnológicos (“esquirolaje tecnológico”).

La docencia es una de las profesiones de riesgo para padecer síndrome de burnout (BO), que es un conjunto de síntomas que se desarrollan por el estrés laboral. Un campo que se está estudiando actualmente para la prevención y tratamiento de este síndrome es el uso de la inteligencia emocional (IE). El objetivo principal de este trabajo es conocer el nivel de IE y BO en docentes de Enfermería de la Universidad de Vigo. En cuanto a la metodología es un estudio cuantitativo, transversal y descriptivo. Se desarrolló en las 4 escuelas de Enfermería de la Universidad de Vigo, que cuentan con 103 docentes, de los que se obtuvo una muestra de 29 docentes. Los datos se obtuvieron de una encuesta realizada a través de Google formularios, que fue realizada entre marzo y abril de 2020. Las variables dependientes (IE y BO) se obtuvieron de los test validados TMMS-24 y MBI-ES. Las variables independientes se agruparon en sociodemográficas, de formación y laborales. Resultados: mujeres 18 (62,1%), titulados en Enfermería 17 (58,6%), titulados en Medicina 5 (17,3%). Percepción emocional =26,59; claridad emocional =30,13; reparación emocional =31,55. Agotamiento emocional =11,59; despersonalización =1,82; realización personal =38,69. Se concluye que el nivel de IE de la población encuestada en este estudio es adecuado, destacando la dimensión de reparación emocional como la más positiva y la percepción emocional como la menos positiva. Respecto al BO la mayoría tiene un nivel bajo, siendo la realización personal la dimensión con más margen de mejora.
Distributed fiber optic radiation sensors

Abstract. The international research efforts focused on the development of radiation
sensors based on optic fibers have their origins in the 1970s (Evans et al., 1978). Generally, the lightweight fiber optic sensors are immune to
electromagnetic field interference and high voltages making them deployable in harsh environments at hard to reach areas where conventional sensors usually will not work at all. A further advantage of such radiation sensors is the possibility of remote and real-time monitoring (Huston et al., 2001). In this work, we present our results achieved in several research activities for development of fiber optic dosimeters. The findings show that both the measurement of the radiation-induced attenuation (RIA) along the entire sensing fiber and the accompanying change in the refractive index of the fiber core can be used for distributed radiation monitoring in the kGy and MGy range, respectively. Depending on the fiber type and material the RIA shows varying response to dose rates, environmental temperatures and the wavelength of the laser source used. Thereby, an operation with visible laser light provides most favorable performance in terms of high radiation sensitivity. Operating at these wavelengths, RIA monitoring could yield high-sensitivity dose measurement with sub-gray resolution and accuracy (Stajanca and Krebber, 2017b); however, conventional optical time-domain reflectometry (OTDR) systems for RIA measurements operating in the visible range suffer from low-spatial resolution, long measurement times and poor signal-to-noise (SNR) ratio. The limitations of the OTDR performance can be overcome by the incoherent optical frequency domain reflectometry (I-OFDR) developed by the Federal Institute of Materials Research and Testing (BAM, Liehr et al., 2009) with potential for dynamic real-time measurement. Over the years, several highly radiation sensitive fibers, such as perfluorinated polymer optical fibers (PF-POF, Stajanca and Krebber, 2017a), phosphorous-doped silica optical fibers (SOF, Paul et al., 2009), aluminium-doped SOF (Faustov et al., 2013) and erbium-doped SOF (Wosniok et al., 2016) have been identified and are commercially available. As mentioned before, the radiation-induced RIA increase is associated with an increase in the refractive index leading also to material compaction in the fiber core. The latter two effects can be used for measuring radiation distribution based on Brillouin scattering in the range of high radiation doses of several MGy (Phéron et al., 2012; Wosniok et al., 2016). When using fiber optic sensors for radiation monitoring, the existing post-irradiation annealing behavior of the optical fiber sensors must also be considered.

Abstract. Part of the process to ensure the safety of radioactive waste disposal is the
predictive modeling of the solubility of all relevant toxic components in a
complex aqueous solution. To ensure the reliability of thermodynamic
equilibrium modeling as well as to facilitate the comparison of such
calculations done by different institutions, it is necessary to create a
mutually accepted thermodynamic reference database. To meet this demand
several institutions in Germany joined efforts and created THEREDA (Moog et
al., 2015). THEREDA is a suite of programs at the base of which resides a relational
databank. Special emphasis is put on thermodynamic data along with suitable
Pitzer coefficients, which enable the calculation of solubilities in
high-saline solutions. Registered users may either download single
thermodynamic data or ready-to-use parameter files for the geochemical
speciation codes PHREEQC, Geochemist's Workbench, CHEMAPP, or TOUGHREACT. Data
can also be downloaded in a generic JSON format to enable the import into
other codes. The database can be accessed via the world wide web:
http://www.thereda.de (last access: 1 November 2021). Prior to release, the released part of the database is subjected to many
tests. Results are compared to results from earlier releases and among the
different codes. This is to ensure that by additions of new and modification
of existing data no adverse side effects on calculations are
caused. Furthermore, our website offers an increasing number of examples for
applications, including graphical representation, which can be filtered by
components of the calculated system.
Twenty years of research on spent nuclear fuel in the context of final disposal at KIT-INE in multinational collaborative projects

Abstract. Disposal of spent nuclear fuel (SNF) in deep geological repositories is considered a preferential option for the management of such wastes in many countries with nuclear power plants. With the aim to permanently and safely isolate the radionuclide inventory from the biosphere for a sufficient time, a multibarrier system consisting of technical, geotechnical and geological barriers is interposed between the emplaced waste and the environment. In safety assessments for deep underground repositories, access of water, followed by failure of canisters and finally loss of the cladding integrity is considered in the long-term. Hence, evaluating the performance of SNF in deep geological disposal systems requires process understanding of SNF dissolution and rates as well as quantification of radionuclides release from SNF under reducing conditions of a breached container. In order to derive a radionuclide source term, the SNF dissolution and alteration processes can be assigned to two steps: (i) instantaneous release of radionuclides upon cladding failure from gap and grain boundaries and (ii) a long-term release that results from dissolution of the fuel grains itself (Ewing, 2015). In this context, research at KIT-INE has focused for more than 20 years on the behavior of SNF (irradiated UO2 and MOX fuels) under geochemical conditions (pH, redox and ionic strength) representative of various repository concepts, including the interaction of SNF with backfill material, such as bentonite as well as the influence of iron corrosion products, e.g. magnetite and radiolytic reactions on SNF dissolution mechanisms. Since 2001, KIT-INE has contributed with experimental and theoretical studies on the behavior of SNF under repository relevant conditions to six Euratom projects viz SFS (2001–2004), NF-PRO (2004–2006), MICADO (2006–2009), RECOSY (2007–2011), FIRST-Nuclides (2012–2014) and DISCO (2016–2021). Moreover, since 2007, overall 4 consecutive projects for the Belgian waste management organization, ONDRAF-NIRAS, were performed on the behavior of SNF under conditions representative of the Belgian “Supercontainer” concept. In this contribution, we summarize major achievements of theses research projects to understand and quantify the radionuclide release from dissolving SNF under repository conditions. In particular, the dependence of radionuclide release on the chemical composition of the aqueous and gaseous phase in the proximity of repositories in different types of host rock is discussed.
Terrestrial photogrammetry: a method to gather data on fractures for DFN modelling from exposed rock surfaces
Authors: Loeckle Filip
Published: November 2021

Abstract. The stochastic generation of discrete fracture networks (DFN) is a method for
modelling fracture patterns used to assess the in situ fragmentation in a
volume of rock. The DFN modelling approach is based on the
assumption that the natural fragmentation of rocks is a function of the length and
connectivity of the fractures within the considered volume of rock. Thus, in order to generate a site-specific DFN, the
primary geometric properties of the fracture surfaces within the
rock volume (especially orientation, size and fracture intensity as well as
the local spatial variability) must be defined as distribution functions (Elmo
et al., 2014). The required base statistics are usually obtained from fracture
analysis on boreholes, exposed rock surfaces or (to a limited extent) 3D
seismics (e.g. Bisdom et al., 2014; Bemis et al., 2014). We adopted a terrestrial close-range photogrammetry approach to capture
several outcrops and analyse fracture traces on the exposed rock surfaces, the chosen
workflow is based around the use of free and open-source software. Images were
acquired from several quarries in the Weschnitzpluton, a
granodioritic to quartz monzodioritic pluton in the Bergstrasse Odenwald
(e.g. Altherr et al., 1999) using a consumer-grade Nikon D5300
DSLR with fixed focal length instead of a drone or Lidar-system for legal
reasons, partially tree-lined outcrops and cost efficiency. Since point clouds
obtained from photogrammetry are inherently dimensionless, we used a spherical
target with compass and bubble level for scale and proper spatial orientation
(Froideval et al., 2019). The exact geolocation is not particularly important
for the task, so the use of GPS, total station or georeferenced ground control
points is not necessary. Dense point clouds were computed using the open
source SfM photogrammetry suite Meshroom (AliceVision, 2021), which can be
used for manual or semi-automatic detection of fracture surfaces and their orientation
(Schnabel et al., 2007) and to generate orthorectified images of the rock surface
to trace fracture lengths and nodes in a GIS (Nyberg et al., 2018). Our
investigations proved terrestrial photogrammetry to be a valuable and easily accessible tool in the
documentation of natural fracture patterns and a robust base for the
generation of DFN networks.
