Aging Process of Polyamidoamine Dendrimers: Effect of pH and Shaking in the Fluorescence Emission and Aggregation-State
Authors: Daniela Igartua , Ybarra David , Cabezas Dario , del Valle Alonso Silvia , Alvira Fernando
Published: November 2020

In the last years, it has been discovered and intensely studied the non-traditional intrinsic fluorescence of PAMAM dendrimers. Nevertheless, their aging process in aqueous suspension is scarcely studied, being unknown the causes of the observed changes in their fluorescence properties. Hence, this work aims to characterize the PAMAM dendrimers of generation 4.0 (DG4.0) and 4.5 (DG4.5) through the aging process at three different pH conditions, stored with or without shaking. We studied, up to 16 days, the UV-Vis absorption, the fluorescence emission, and the size of dendrimers/aggregates. In a different way than the already published work, we demonstrated that there is no chemical change in dendrimers through the aging process, even though changes in fluorescence emission were observed. Besides, we have put in evidence that changes in the agglomeration patterns of dendrimers would not be related to change in the fluorescence emission thought aging. Moreover, we demonstrated that DG4.5 formed large aggregates in water that need to be disrupted by shaking previous to an in vivo administration.
Las estrategias del creer en Los ocho más odiados, de Quentin Tarantino
Authors: Núñez Alberca Alejandro
Published: November 2020

El presente artículo propone un análisis semiótico-estructural de la película de Quentin Tarantino Los ocho más odiados (The Hateful Eight, 2015). Nuestro trabajo incorpora elementos provenientes de la narratología fílmica, en particular la idea del unreliable narrator de Emily Anderson, quien plantea la posibilidad de un narrador no confiable al interior del discurso. El análisis demuestra que el filme, tanto al nivel del relato como del discurso, presenta una serie de simulacros manipulatorios que les permiten a sus actantes organizar la dimensión cognitiva del saber y el creer. Se revela un dispositivo que no solo permite a los personajes engañar a otros con sus discursos, sino también al enunciador que opera en un nivel superior. De este modo, el filme convierte la subinformación y la contrainformación en sus instrumentos clave.

Coronaviruses was discovered in the mid-1960s that affect humans. In 2019, Wuhan city of Hubei, China, there was an out-break of "coronavirus disease (COVID-19)" which is the result of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is induced by a novel enveloped virus having single-stranded RNA. It transmitted rapidly affecting more than 200 countries globally, so, the World Health Organization has declared it as a pandemic. SARS-CoV-2 presently is a 7th amongst known coronaviruses that cause infection in people, after 229E and OC43 (earliest studied viruses in human patients suffering from a common cold). It has infected humans in all age groups, of all ethnicities, both males and females while spreading through communities at an alarming rate. Infected patients experience common cold-like symptoms along with raised temperature, non-productive coughing and difficulty to breathe. It is considered as a relative of severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), COVID-19 is caused by a beta coronavirus named SARS-CoV-2, which affects the lower respiratory tract. Besides, SARS-CoV-2 also harms different organs. Till today, there is comprehensive knowledge about the extent and management of COVID-19-related disorders other than pulmonary system. The present review is an overview of systemic manifestations of COVID-19 that may affect gastrointestinal, cardiovascular, urinary, reproductive, hepatocellular or neurological systems.

Ayurveda – the nectar of ancient disease curing system exists since Vedic period s full of heritage and ts antiquity s well-known. Ayurveda s deals with cure and maintain health through its remarkable potency, viral infections are liable for many illnesses, and up to date, outbreaks have raised public health concerns. Despite the supply of the many antiviral drugs, they're often unsuccessful thanks to the generation of viral mutants and fewer effective against their target virus. Identifying novel antiviral drugs is therefore of critical importance, and natural products are a superb source for such discoveries. Viruses pose a worldwide threat and add severe medical and social problems to humanity. They are the main contributors in many minor and major outbreaks, epidemics and pandemics worldwide like Swine Influenza, Avian Influenza, and Dengue fever. Even though various types of treatment methods are available to cure viral diseases, like chemotherapy, but owing to their potential for mutation and emergence of new strains and developing resistance towards drugs, Viruses are evolving fast. This necessitates the look for new antiviral compounds that are stiffer and effective against viruses with no or less adverse side effects the concept and treatment line must be going through the Ayurved. Some Home Remedies such as Eat Guduchi or Tulsi daily can increase your immunity. Drinking Turmeric milk is suitable for the upkeep of health. Taking Ashwagandha is one of another herb for fighting with such conditions. Eating 1-2 leaves of Neem also can work well within the prevention of viral infections.

Currently the world is dealing with the infection of COVID-19 which has recently been declared as Pandemic by WHO. The quick spread everywhere throughout the world has raised worries about the chance of transmission of the infection from individual to individual. The present study is aimed to review the information available about COVID19 and similar diseases in Ayurveda literature such asCharakaSamhita, SushrutaSamhita, AshtangaHrudayaandvarious research studies related to the topic.Ayurveda an antiquated clinical science has unmistakably depicted Aupsargikarogas (Communicable diseases), their mode of transmission, cause, cure and prevention too.Janapadodhwamsa,  thediseases which affect a major part of population and itsfour causative factors such as pollution of Vayu(Air) and Jala (Water) along with the changes inKala(Time) andDesha(Region)explained in Ayurveda. With respect to treatment, Ayurveda advocates prevention as the first step and then cure of diseases, through Nidana Parivarjana (Avoidance of causes),Shodhan (Bio purification) and Shaman(Curative and Palliative care). With the help of Panchakarma (Five bio purificatory therapies)and Rasayana (Rejuvenation therapy), these diseases can be prevented well. Ayurveda can be helpful to reduce the morbidity and mortality.The current review portrays how Ayurveda can assist with combatting the developing challenges of communicable infections.
That Old Devil Called ‘Statistics’: Statistics Anxiety in University Students and Related Factors
Authors: Puklek Levpušček Melita , Cukon Maja
Published: November 2020

The present study investigated relationships between statistics anxiety (SA), trait anxiety, attitudes towards mathematics and statistics, and academic achievement among university students who had at least one study course related to statistics in their study programme. Five hundred and twelve students from the University of Ljubljana completed the Statistics Anxiety Rating Scale (STARS), State-Trait Anxiety Inventory, and answered questions about their perceptions of mathematics and statistics. The results showed below-average mean scores on the STARS dimensions, except for the Test and Class Anxiety with the average score around the midpoint of the scale. Female students reported higher levels of SA than male students did. The highest levels of SA were reported by students who perceived mathematics and statistics as a threat. The subscales of the STARS correlated positively with students’ trait anxiety. Students who reported less enjoyment in mathematics in high school perceived statistics to be a less worthy subject and had a lower computation self-concept. Students who had better mathematics performance in high school and higher average study grades also reported a higher computation self-concept. In the present study, we translated the STARS questionnaire into Slovenian and confirmed the six-factor structure of the questionnaire. The results provide a basis for further research on statistics anxiety and further validation of the STARS questionnaire. The results can also aid statistics teachers in better understanding students’ worries, fears, and attitudes towards statistics and in learning about the factors that affect students’ statistics anxiety and their work in the course.
Manejo de traumatismo nasal en emergencias
Authors: Solis Tobar Jimenez Ricardo Javier , Astudillo Lalangui Pamela Daniela , Sandoval Castro Karla Sarai , Galarza Benavides Mauricio Wladimir
Published: November 2020

Los expertos reconocen que los traumatismos nasales son reportados entre las principales causas de atención en los centros de asistenciales de salud, tanto en los servicios de otorrinolaringología como en los de emergencia y ello, posiblemente, se deba al hecho de que la nariz, al formar parte de la estructura central del rostro, sea una de las partes anatómicas más sensible y vulnerable ante cualquier lesión o evento traumático. La ocurrencia de éstos, frecuentemente derivan en anormalidades estéticas importantes y/o cambios funcionales. Es precisamente todo lo antes expuesto lo que ha propiciado el interés por desarrollar el presente estudio. Para su desarrollo se ha determinado adelantar un trabajo investigativo de diseño bibliográfico, a su vez delimitado a una metodología de revisión. Con los resultados se ha logrado describir algunas acepciones vigentes, causas (etiología), síntomas (signos), diagnóstico y manejo (tratamiento) en emergencia del traumatismo nasal. En conclusión, el objetivo del manejo o tratamiento del trauma nasal básicamente se sustenta en el control de la epistaxis y del hematoma septal, sin dejar de considerar, en la medida de lo posible, la obtención de un tracto aéreo satisfactorio y restaurar la apariencia original de la nariz.

Published: November 2020

La hipertensión intracraneal idiopática (HII) es un síndrome caracterizado por un aumento de la presión intracraneal de causa desconocida, que conduce a dolor de cabeza intenso, papiledema y alteraciones visuales. Su nombre anterior, pseudotumor cerebri, ha ganado popularidad recientemente. Los factores de riesgo más fuertes y consistentes se presentan en pacientes de sexo femenino y en aquellos que padecen de obesidad. Con poca frecuencia, la HII puede presentarse en ausencia de papiledema mostrando un perfil de cefalea similar a la cefalea crónica diaria con características migrañosas. Se han propuesto varios mecanismos para explicar la etiología de este trastorno asociado con diversas condiciones clínicas. En los últimos años, se han presentado algunos factores inflamatorios, péptidos natriuréticos y acuaporinas como posibles contribuyentes de la patogenia. Por otro lado, algunos investigadores han informado que la estenosis del seno transverso bilateral se observa en la mayoría de los pacientes con HII; por lo tanto, en algunos pacientes se utiliza la colocación de un stent de seno dural. Ninguna teoría ha sido capaz de proporcionar una respuesta completa y no existe consenso sobre la causa exacta de la HII. El objetivo de esta revisión fue discutir los nuevos conocimientos sobre la misteriosa patogénesis de la IIH.

Authors: Santos Rogério César dos , Gontijo Cleyton Hércules
Published: November 2020

A análise praxeológica de Yves Chevallard (1999) tem sido amplamente utilizada como ferramenta de investigação dos fenômenos educacionais, em particular em se verificar como alunos, professores, livros didáticos e instituições têm relacionado a teoria à prática dentro dos conteúdos a serem trabalhados em sala de aula (práxis = prática, logos = razão). Ela pode ser realizada em várias instâncias: propostas de atividades de sala de aula, organizações de livros, organizações de documentos oficiais, experiências de professores, dentre outros. Neste artigo, foi realizado um estado da arte das análises praxeológicas debruçadas sobre livros brasileiros de matemática, através de levantamentos por palavras-chave na Biblioteca Digital Brasileira de Teses e Dissertações. Após a pesquisa, verificou-se que é ampla a abordagem da análise praxeológica sobre livros didáticos, e que, em geral, tal análise propicia uma boa verificação de como os conteúdos em matemática estão organizados nas obras, de como os livros poderiam ser complementados com maiores explicações das técnicas matemáticas utilizadas, e como os mesmos estão em sintonia com os documentos oficiais.

Published: November 2020

Os saberes museais, são saberes relacionados aos espaços de educação não formal, desde os seus aparatos e o conhecimento científico atrelado a eles, bem como as interações/comunicações que ocorrem dentro dos museus. Neste artigo foi realizado estudo envolvendo sete mediadores de um espaço de educação não formal, com o objetivo de analisar seus discursos relativos aos saberes utilizados na visitação, e suas concepções sobre o museu e a formação de mediadores. Para tanto, os mediadores foram acompanhados em visitas de grupos escolares ao local, e entrevistados. A partir dos dados coletados e dos referenciais teóricos sobre saberes docentes e de museus, foram construídos os Saberes dos Mediadores Museais. Estes saberes remontam significados oriundos das falas provindas de entrevistas e das visitas mediadas, possibilitando novos significados para seus discursos. O estudo sugere uma nova classificação de saberes museais através da análise dos discursos dos mediadores, o que pode promover uma reflexão no uso de metodologias e práticas de ensino-aprendizagem utilizada em museus bem como o uso de tais saberes para a formação de profissionais tanto nas universidades como nestes espaços.

Improving Prospect Evaluation by Integration Saturation Height Function into The Resource Assessment Workflow
Authors: Sugiharto Y.
Published: November 2020

This paper will discuss saturation modelling weighted by area-depth and to determine a field’s hydrocarbon in place, it is necessary to model the distribution of hydrocarbon and water throughout the reservoir. Results comparison to “average” saturation values obtained from reservoir summation are also described to improve the prospect evaluation. The unconventional approach of water saturation determined using SHF weighted to volume is in the appreciation of 3D earth model, applicating the distribution of saturation 360-degree geometry, and addressing the reservoir heterogeneity. The common saturation values are obtained from reservoir summation with applied petrophysical cut-off. The workflow to estimate the potential resources of an exploration opportunity usually begins with a geophysicist interpreting seismic. Then, a geologist constructs a geological model with which to calculate hydrocarbon in place. As petrophysical data tends to be sparse in most new venture areas, petrophysicists are seldom called on to help in the process. This omission leads to major errors in the prospect evaluation. The problem stems from lack of communication and understanding between the various disciplines contributing to the various parts of the workflow. The SHF greatly impacts resource calculations and is used by geologists to predict the saturation in the reservoir for a given height above the free water level. Many bad practices occur in the initial setting up of Monte Carlo simulation model of hydrocarbon-in-place. For example, failure to consider the petrophysical model leads to incorrect distributions of the input parameters, neglecting to link dependent petrophysical parameters, and using “average” saturation values and ignoring height dependency.
Petroleum Systems Analysis of The Tungkal PSC Area, South Sumatra – A Means of Adding New Life to A Mature Area
Authors: Livsey A.
Published: November 2020

South Sumatra is considered a mature exploration area, with over 2500MMbbls of oil and 9.5TCF of gas produced. However a recent large gas discovery in the Kali Berau Dalam-2 well in this basin, highlights that significant new reserve additions can still be made in these areas by the re-evaluation of the regional petroleum systems, both by identification of new plays or extension of plays to unexplored areas. In many mature areas the exploration and concession award history often results in successively more focused exploration programmes in smaller areas. This can lead to an increased emphasis on reservoir and trap delineation without further evaluation of the regional petroleum systems and, in particular, the hydrocarbon charge component. The Tungkal PSC area is a good example of an area that has undergone a long exploration history involving numerous operators with successive focus on block scale petroleum geology at the expense of the more regional controls on hydrocarbon prospectivity. An improved understanding of hydrocarbon accumulation in the Tungkal PSC required both using regional petroleum systems analysis and hydrocarbon charge modelling. While the Tungkal PSC operators had acquired high quality seismic data and drilled a number of wells, these were mainly focused on improving production from the existing field (Mengoepeh). More recent exploration-driven work highlighted the need for a new look at the hydrocarbon charge history but it was clear that little work had been done in the past few year to better understand exploration risk. This paper summarises the methodology employed and the results obtained, from a study, carried out in 2014-15, to better understand hydrocarbon accumulation within the current Tungkal PSC area. It has involved integration of available well and seismic data from the current and historical PSC area with published regional paleogeographic models, regional surface geology and structure maps, together with a regional oil generation model. This approach has allowed a better understanding of the genesis of the discovered hydrocarbons and identification of areas for future exploration interest.
Case Study: Maximizing Business Performance by Optimizing Supply Chain Of LNG-C Distribution of 9 Gas Power Plants with A Capacity of 780 MW in Eastern Indonesia
Authors: Wara A. D.
Published: November 2020

The Government of Indonesia plans to build 9 gas power plants in South Kalimantan, South Sulawesi and Southeast Nusa Tenggara with a total power capacity of 780 MW with an estimated actual gas demand of 46.56 MMSCFD which are planned to be supplied by the Bontang terminal, DS-LNG, Masela LNG, and Tangguh LNG. LNG-C logistics optimization is needed to get the best transportation scenario regarding the eastern region which consists of scattered islands and inadequate infrastructure. This study analyzes and evaluates the best-case scenarios by comparing the time and cost variables. The process of planning the supply chain starts from determining the upstream-downstream distribution scheme and then calculates the shipping distance which results in the determination of the quantity, capacity and shipping of the LNG-C. Based on the analysis and calculation of the logistics, it is concluded that there are 3 divisions of clusters of Kalimantan-Sulawesi, NTT and NTB having estimated needs in a row of 18.06, 18.8, and 9.7 MMSCFD with the Milk-Run transportation method. Logistics optimization results show that scenario 1 has an efficiency value of 87% with an LNG-C transport capacity of 0.35 MMSCF, a roundtrip cruise time of 8.6 days and the number of shipments is 36 / year. The detailed analysis of costs in scenario A is 1-2 USD / MMBTU for the milk and run transportation method, 1.49-1.73 USD / MBTU for LNG-C transport costs, and regasification costs which are 1.0-3.7 USD / MMBTU. Based on the above results it can be calculated that the price of gas in the first year of implementation was 13.4 USD / MMBTU, so the total value below this supply chain was Rp.8,812,876,800.00. Therefore, this idea was created as a solution for the initial steps for the utilization of the domestic natural gas distribution
Characteristics of Facies Associations, Ichnofacies and Microfossils for Depositional Environment Interpretation of The Clastic Pulau Balang Formation, Samarinda
Authors: Andika B.
Published: November 2020

The Kutai Basin contains prolific reserves of oil and gas. The study of depositional environments is one of the goals of oil and gas exploration. The location of this research is situated in the Tanah Merah area, Samarinda. The objective of this research was to analyse outcrops of the Pulau Balang Formation exposed in the Tanah Merah area to determine the depositional environment. Site specific studies were conducted at 3 localities in this area; TM1, TM2 and TM3. This study combines geological mapping, measured sections, facies analysis, petrography, ichnofacies analysis and microfossil analysis. Geological mapping was carried out to determine the distribution of rock units and geological structures. Measured sections were used for facies analysis and the identification of sedimentary structures and ichnofacies. Petrography was carried out to determine the mineral content of rocks and microfossil analysis for palaeobathymetric environmental analysis. The geological structure of the study area comprises a NE-SW trending anticline and syncline and a left lateral strike-slip fault with E-W direction. The study area is entirely within the Middle Miocene age Pulau Balang Formation and can be divided into three facies associations. The TM1 facies association comprises strata interpreted to be deposited in a supratidal marsh and intertidal flat environment. The TM2 facies association comprises strata interpreted to be deposited in a subtidal, intertidal, and supratidal environment. The TM3 facies association comprises strata interpreted to be deposited in a shoreface environment. The petrography of the study area indicates that rock units predominantly comprise quartz wacke and lithic wacke. Two ichnofacies were identified in the research area 2, namely the Skolithos ichnofacies and the Skolithos-Cruziana ichnofacies and contain ichnogenera namely Ophiomorpha, Skolithos, Planolites, Thalassinoides, Paaleophycus. Microfossil analysis found benthonic foraminifera species including Nodosaria lamellala, N. radicula, Vaginulinopsis tricarinata, Lagena costata, Striatissima vaginulina, Bulimina lappa, Planularia auris, Quinqueloculina seminulum, Bolivina punctata and Lahena laevis. Based on the presence of these microfossils and ichnofacies, it is interpreted that the research area was deposited in a neritic-bathyal environment.

Toprağa uygulanan gübrelerin yarayışlı hale geçerek bitkiler tarafından alınması besin elementine bağlı olarak birçok faktör tarafından etkilenmektedir. Gübrelerin etkinlik derecesini arttırmak için kontrollü salınımlı gübreler (KSG) yeni bir teknoloji olarak geliştirilmiştir. Yapılan bu çalışmada N, P ve K içerikleri yönünden benzer özellik gösteren 5 farklı KSG’nin (115, 414, 715, 815 ve 2415) ve farklı uygulama (serbest veya paketli) metotlarının İtalyan çiminin gelişimi üzerine etkisi kontrollü şartlarda belirlenmiştir. Torf ile doldurulmuş saksı içerisinde yetiştirilen bitkilere KSG’ler paket halinde ya da serbest halde uygulanmıştır. Tohum ekiminden itibaren 4 aylık periyod içinde gübrelerde zamanla meydana gelen toplam ağırlık kayıpları, besin elementi içeriğindeki meydana gelen kayıplar, birim gübre karşılığında toplam üretilen yaş ve kuru biomas ve saksı başına hasatla kaldırılan toplam besin elementi miktarları belirlenerek gübreler ve uygulama şekilleri karşılaştırılmıştır. Sonuç olarak, 414 (% 29.90) ve 815 (% 15.03) nolu gübrelerde ağırlık kaybı en az olurken biomas üretimi en fazla olmuştur. Her iki gübrenin etkinliği diğerlerine oranla istatistiksel olarak önemli düzeyde daha yüksek olduğu tespit edilmiştir. Birim gübre karşılığında üretilen biomas miktarına göre ise 815 açık farkla öne çıkmıştır. Uygulama şekli açısından “serbest” uygulamanın daha etkili olduğu tespit edilmiştir. Özellikle saksıda yetiştirilen ve uzun hayat döngüsüne sahip bitkilerde 815 nolu gübrenin serbest uygulama şekli önerilmiştir.

The study assessed the fish farmers’ livelihood in Camp 74 community, Oshimili South Local Government Area of Delta State. The study focused on the farmer’s socioeconomic profile, contribution of fish farming to fish farmers’ livelihood status, challenges of fish farming and strategies employed by fish farmers in tackling challenges. By purposive sampling, a sample size of 50 respondents was used for the study. A well structure questionnaire was used in conducting the research. The data collected were subjected to frequency distribution, linear Regression and Chi-square. The results showed that more respondent (74%) had social benefit from fish farming, youth respondents (62%) are engaged in fish farming as source of livelihood. Respondents (68%) attested that fish farming reduced hunger and increased fish availability all year round with better income generation and savings. It was revealed that the various contributions of selected livelihood components had a pooled mean = 1.67. Again, with the index value = 0.56, it implies a very high impact contribution of aquaculture to livelihood pattern. However, challenges to fish farming were among others high cost of fingerlings (mean = 3.54), weak government support (mean = 3.22) and non-visitation of extension workers (mean = 3.06). Respondents most important strategies to overcome challenges were assessed to improved varieties of fingerlings (mean = 3.42) and inclusion cooperative society in feed supply (mean = 3.12). The regression and chi-square results were significant (p<0.05). Based on these findings, it is recommended that government should participate more in fish farming activities to improve livelihoods

Authors: KARABIYIK Şenay , ETİ Sinan
Published: November 2020

Bu araştırmada, Yerli turunç anacında farklı tozlama uygulamaları sonucunda meyve, tohum ve embriyo gelişimi ile nuseller embriyo oluşum mekanizmasına ilişkin incelemelerin yapılması amaçlanmıştır. Çalışmada; Yerli turunç anacında İzolasyon, Serbest tozlanma, Yabancı tozlama ve Kendileme uygulamaları yapılmıştır. Çalışma sonucunda nuseller embriyo köken hücre (NEKH)’lerinin; tohum taslağının kalaza kısmındaki nusellus dokusundan olmak üzere tozlanmaya bağlı olarak döllenme sonrasında oluştukları, gelişimlerinin ilk aşamasında nusellus hücrelerinden beslendikleri, embriyo kesesine giriş yaptıktan sonra ise endospermi tüketerek gelişmelerine devam ettikleri belirlenmiştir. Yapılan incelemeler sonucunda Yerli turunç anacında Yerli üç yapraklı ile yabancı tozlama yapılması durumunda çiçek tozu çim borusu gelişiminin yavaş ve az sayıda olduğu belirlenmiştir. Ayrıca, yabancı tozlama uygulaması sonucunda gelişen sınırlı sayıdaki tohum taslaklarında da endosperm gelişiminin yeterli düzeyde olmadığı tespit edilmiştir. Serbest tozlanma ve Kendileme uygulamalarında ise bu tip durumlar oluşmamıştır. Sonuçta, Yerli turunç anacının Yerli üç yapraklı ile tozlanması durumunda, yeterli eşeysel uyuşmanın gerçekleşmemesi nedeniyle başlangıçta oluşan NEKH’lerinin olgun birer embriyoya dönüşebilmesinin sınırlı olduğu, ayrıca embriyo kurtarma için kritik dönemin tozlanmadan sonra 65. ve 75. günler arasında olduğu belirlenmiştir.

Testimonio: trauma, verdad y reparación
Authors: Lira Elizabeth
Published: November 2020

En procesos de transición política, de dictaduras y guerras civiles a gobiernos elegidos por vía democrática, los testimonios de víctimas han sido herramientas de denuncia que han dado lugar a procesos de reconocimiento y reparación en contextos judiciales, terapéuticos y de investigación social. También son fundamento para la construcción de memorias de personas y comunidades. Describimos el testimonio como una herramienta terapéutica de experiencias políticas traumáticas en el ámbito clínico durante la dictadura militar en Chile (1973-1990). Los testimonios de las víctimas se constituyeron como piedra angular del tratamiento del pasado, el reconocimiento y reparación de las víctimas y la reconstrucción de la verdad y la memoria colectiva en las décadas siguientes.
Testimonios mayas durante el conflicto armado interno en Guatemala
Authors: Macleod Morna
Published: November 2020

Se analizan testimonios de activistas mayas durante el conflicto armado en Guatemala, vertidos en el Tribunal Permanente de los Pueblos, respaldados con otras fuentes, en especial la revista Polémica, de Costa Rica. Poco se ha escrito sobre testimonios emitidos durante la guerra: ¿qué características, potenciales y constreñimientos tiene la denuncia de atrocidades en tiempo real? Después de analizar testimonios y comunicaciones actuales con los actores, argumento que testificar en la guerra recobra agencia, urgencia para salvar vidas y aporta fuerza política a la literatura de la memoria. Sugiero que las voces mayas enriquecen los testimonios-denuncia del Tribunal al incluir otras reivindicaciones, pero lo que se retoma y omite de ellos teje otras violencias silenciadas.

Quality Models for Open, Flexible, and Online Learning
Authors: Ossiannilsson Ebba
Published: November 2020

This article is based on research conducted for the European Commission Education & Training 2020 working group on digital and online learning (ET2020 WG-DOL) specifically regarding policy challenges, such as the following: 1) Targeted policy guidance on innovative and open learning environments under outcome; 2) Proposal for a quality assurance model for open and innovative learning environments, its impact on specific assessment frameworks and its implication for EU recognition and transparency instruments. The article aims to define quality in open, flexible, and online learning, particularly in open education, open educational resources (OER), and massive open online courses (MOOC). Hence, quality domains, characteristics, and criteria are outlined and discussed, as well as how they contribute to quality and personal learning so that learners can orchestrate and take responsibility for their own learning pathways. An additional goal is to identify the major stakeholders directly involved in open online education and to describe their visions, communalities, and conflicts regarding quality in open, flexible, and online learning. The article also focuses on quality in periods of crisis, such as during the pandemic in 2020. Finally, the article discusses the rationale and need for a model of quality in open, flexible, and online learning based on three major criteria for quality: excellence, impact, and implementation from the learner’s perspective.
Bacteriological and physico-chemical assessment of untreated drinking water used by residents in Ofougbene- Izon-Borotu Community, Delta State
Authors: Otajevwo Dafinone Festus  , Dio Princess Tamaramiene
Published: November 2020

This study was aimed at assessing the bacteriological and physio-chemical qualities of the ground well water which is the only available drinking water to residents of Ofougbene community of Burutu Local Government Area, in order to check it's fitness for drinking and evaluate the awareness of the people about dangers of drinking untreated water. Seven water samples coded Station1-Station 7 were obtained from seven different ground wells in the study area. Bacteriological assessment was done by Most Probable Number (MPN) technique while physical, chemical and organic analyses of the water samples were carried out by known standard methods. Bacterial organisms isolated were Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes and Staphylococcus epidermidis. All ground water samples contained total aerobic bacterial load ranging from 1.8 x 103 to 7.0 x 103 CFU/ml. The mean ± standard deviation values of pH, electrical conductivity, color, turbidity, Total Dissolved Solids, Suspended Solids, alkalinity, chloride, hardness, phosphates, nitrates, sulphates, calcium, magnesium, Dissolved Oxygen and Biological Oxygen Demand were: 5.8±16.43, 51.4±27.0uS/cm, 22.4±12.32mg/l, 11.8±5.14mg/l, 28.4±15.10mg/l, 3.8±3.80mg/l, 15.4±12.49mg/l, 21.12±0.02mg/l, 53.3±32.72mg/l, 0.20±0.04mg/l, 2.77±0.27mg/l, 9.28±3.60mg/l, 11.9±12.10mg/l, 1.7±0.51mg/l, 5.9±0.58mg/l and 3.04±0.51mg/l respectively for all the water samples assessed. Whereas water quality status for all samples was unsatisfactory, water quality concern was high. Compared to reference values provided by Standard Organization of Nigeria (SON) and presence of pathogens, we conclude that the ground water used by the people of the community is unfit for human consumption. This is for the immediate attention of the Public Health Authorities of both the LGA concerned and the Delta State Government.
