AbstractThe study of the Periodic Table is always a great challenge, due to the fact that students do not understand the periodic properties linked to how the elements were organized, in addition to the difficulty understanding that these properties are related to the substances formation. The present work aimed to approach the chemistry history in the elements classification, building together with the student an understanding and appropriation of the knowledge that was used to construct the periodic table. This study was developed with 35 students of Youth and Adult Education (EJA) from a state public school in the north of the state of Espírito Santo, adopting the new modality of semi-presential education. From our didactic proposal, it was evident that the students presented an adequate understanding of the main aspects of Historic construction of the Periodic Table, identified in the participation of the proposed activities in a semi-presential approach of EJA.

Formação Continuada para o Educador: Necessária e Assegurada ou Apenas Aconselhável e Voluntária?
Authors: Veçozzi Thais Antolini
Published: March 2022

ResumoA sociedade organizada como se conhece possui uma forte dependência dos educadores, o que inicialmente aponta para a valorização do aperfeiçoamento contínuo de sua prática. Apesar disso, ainda não se têm claro se a formação continuada é assegurada legalmente através de instrumentos institucionalizados que a fomentem ou se é apenas aconselhável e dependente dos recursos financeiros do próprio educador. Este estudo buscou responder a esta questão e teve o intuito de contribuir no avanço do direito e acesso à educação. Para isso, foi realizada uma análise crítica de textos bases sobre formação continuada na Educação Básica e no Ensino Superior e o levantamento da legislação brasileira que apoia e sustenta o processo. Além disso, discorreu-se sobre como ocorreu a adequação do processo de ensino-aprendizagem durante a pandemia do coronavírus e quais as dificuldades enfrentadas pela comunidade escolar e acadêmica sem amparo tecnológico, intelectual e financeiro. Ao longo da discussão sobre necessidade de atualização digital dos educadores, chegou-se ao entendimento de que a formação continuada possui resguardo legal e que há caminhos para que seja realizada. Apesar disso, são os próprios educadores que têm acabado arcando com os custos deste processo formativo, algo intensificado diante da adequação das atividades na pandemia do coronavírus.

AbstractOrganized society has a strong dependence on schools, universities and educators, which initially points to the valuation of continuous improvement of those places and education practice. Despite this, it is not clear whether continuing education is legally guaranteed through institutionalized instruments that foster it or whether it is only advisable and dependent on the educator's financial resources. This study sought to answer this question and aimed to contribute to the right and access promotion to education. For this, a critical analysis of basic texts on continuing education in basic education and higher education was carried out and a survey of Brazilian legislation that supports and sustains the process. Also, it was discussed how the teaching-learning process was adapted during the new coronavirus pandemic and what the difficulties were faced by the school and academic community without technological, intellectual, and financial support. Through the discussion about the need for educators' digital updating, it was concluded that that continuing education has legal support and that there are ways to do so. Despite this, the educators themselves are the ones who end up bearing the costs of this training process, a problem intensified given the adequacy of activities in the pandemic of the new coronavirus.

Published: March 2022

Hepatocellular carcinoma (HCC) is a cytotoxic chemotherapy-resistant tumor and most HCCs arise in a background of liver cirrhosis of various causes. Although the IMBrave150 trial showed remarkable advancements in the treatment of unresectable HCC with atezolizumab plus bevacizumab (AteBeva), therapeutic outcomes were unsatisfactory in more than half of the patients. Accordingly, many ongoing trials combine conventional modalities with new drugs such as immune checkpoint inhibitors for better treatment outcomes, and they are expected to benefit patients with limited responses to conventional treatment. Here, two patients with advanced stage HCC with preserved liver function and good performance status showed partial response after treatment with combination or sequential therapy of AteBeva, hepatic arterial infusion chemotherapy, radiation therapy, and transarterial chemoembolization. These findings indicate the efficacy of multidisciplinary treatment against advanced HCC. Additional studies are required to establish optimal treatment strategies.

Published: March 2022

Arabica coffee is one of the main crops in Brazil and requires balanced nutrition. Among the nutrients, phosphorus is essential in planting so that seedlings can be successful in the after transplanting, allowing a good development and growth. The use of quality seedlings and balanced fertilization is essential for this, however, Brazilian soils, due to their mineral origins, have the characteristic of adsorbing part of the applied phosphorus, making it unavailable to plants. Therefore, the objective of this work is to verify if the sources of phosphorus when applied to the soil can be more efficient in relation to the growth and initial development of the coffee tree. The study was carried out in randomized blocks with five treatments and five replications: T1 - formulation 02-10-00; T2 - formulation 00-15-00; T3 - formulation 10-49-00; T4 - formulation 00-19-00; T5 - control, where phosphorus was not applied. After 120 days, after planting, the characteristics of the seedlings were measured, verifying root length, plant height, fresh matter, dry matter and leaf area index. Data were submitted to analysis of variance and Scott-Knott test with 5% probability. It was concluded that the treatments T1 (02-10-00) and T3 (10-49-00) provided better coffee development, proving to be a valid option for the coffee grower aiming at a better performance of phosphorus (P), an element of great complexity in plant nutrition in tropical soils.
Ámbito de aplicación del derecho de la competencia

Las normas de defensa de la competencia utilizan un concepto material de empresa, en el que es indiferente la forma jurídica de la entidad, su naturaleza pública o privada y su modo de financiación. Lo relevante es que lleve a cabo una actividad económica. No se aplican, pues, a las actividades que se organizan en base a criterios de solidaridad. Las autoridades administrativas no pueden tampoco ser sancionadas por prácticas anticompetitivas cuando ejerzan potestades públicas. No obstante, dicha actuación podrá ser anulada por contravenir las normas de defensa de la competencia. No se aplican tampoco a las restricciones amparadas en el derecho de la UE o en leyes estatales, ni a las conductas que sean objeto de regulación sectorial.
Algunas precisiones sobre los presupuestos y el alcance del control judicial de la inactividad reglamentaria al hilo de la Sentencia del Tribunal Supremo de 5 de abril de 2018
Authors: Marina Jalvo Belén
Published: March 2022

En el control de la inactividad reglamentaria, y tratándose de supuestos de omisiones reglamentarias parciales, los tribunales han admitido la posibilidad de condenar a la Administración a incorporar en un reglamento una concreta previsión normativa, siempre previa constatación de la existencia del deber legal de dictar una disposición en un determinado sentido, pero sin incidir en otros aspectos discrecionales del ejercicio de la potestad reglamentaria. La STS de 5 de abril de 2018 ha enjuiciado un supuesto de inactividad reglamentaria total y ha condenado al Gobierno a dictar el reglamento omitido en un plazo determinado de tiempo, por estimar que tanto la obligación de dictar el reglamento como parte del contenido del mismo y el deber de promulgarlo dentro de un plazo específico estaban establecidos en la ley. La sentencia matiza así el carácter enteramente discrecional que hasta esa fecha la jurisprudencia ha venido predicando del ejercicio mismo de la potestad reglamentaria y de la elección del momento oportuno para su ejercicio. El fallo de la STS de 5 de abril de 2018 no debe entenderse fuera del contexto en que se dicta, y a pesar de que no todos sus pronunciamientos sean acertados, conviene resaltar la relevancia de algunas de las consideraciones que realiza, pues pueden permitir una ampliación razonable del alcance del control judicial de la inactividad reglamentaria.

Authors: Rodríguez Pontón Francesc J.
Published: March 2022

La Sentencia del Tribunal Supremo 1361/2018, de 5 de septiembre, resuelve un recurso relativo a uno de los casos más conocidos de ayudas de Estado declaradas por las autoridades europeas contrarias al derecho de la Unión Europea, en el marco de las «vacaciones fiscales vascas». La empresa beneficiaria de la ayuda y obligada a devolverla pretende una indemnización por responsabilidad patrimonial y alega el principio de confianza legítima. El Tribunal Supremo considera que en las circunstancias de este caso no procede estimar dicha responsabilidad patrimonial. Este comentario trata de contextualizar los elementos más relevantes del caso en el marco del derecho europeo de ayudas públicas.
La demolición de inmuebles y el artículo 108.3 LJCA: análisis de los recientes pronunciamientos judiciales
Authors: Arroyo Alfonso , Rodríguez Florido Iván
Published: March 2022

En el año 2015 se modificó el régimen jurídico de la ejecución de sentencias en el orden contencioso-administrativo, concretamente, en lo que se refiere a aquellas que ordenan la demolición de un inmueble. Se incorporó el apdo. 3 al art. 108 de la Ley 29/1998 Reguladora de la Jurisdicción Contencioso-Administrativa, según el cual, cuando se ordenase la demolición de un inmueble, se debería exigir, como condición previa, la prestación de garantías suficientes para responder del pago de las indemnizaciones debidas a terceros de buena fe. Este novedoso precepto, colmado de conceptos jurídicos indeterminados, choca frontalmente con la ejecución de sentencias y ha generado múltiples interrogantes en cuanto a su aplicación práctica. En este sentido, el Tribunal Supremo se ha pronunciado en distintas ocasiones interpretando este precepto, cuya aplicación práctica ha quedado diluida y relegada en aras de la ejecutividad de las resoluciones judiciales y la no imposición de trabas a la demolición de los inmuebles, configurándose como un deber hacer en la ejecución de estos fallos de naturaleza cautelar. Este trabajo trata de ubicar el citado precepto en su contexto normativo y, posteriormente, sinte tizar los distintos pronunciamientos emitidos por parte del Tribunal Supremo, algunos de ellos desde una visión crítica.

Authors: Hariyanto Duwi , Permana Sidik
Published: March 2022

The natural circulation loop is one of the design concepts of a cooling system in new advanced reactors that has attracted many researchers to develop it. This study aimed to perceive the effect of horizontal width variation on the thermal behavior of a single-phase Natural Circulation Loop (NCL). NCL apparatus with a vertical heater and a vertical cooler was designed for experimental study. The height of the loop was 100 cm while the width of the loop was varied at 50 cm and 100 cm. The heater was designed using Nichrome wire on the outside of the stainless pipe while the cooler was designed using pipe-in-pipe with water flowing through the annulus. Arduino microcontroller and K-type thermocouple sensors were used in temperature data acquisition. XAMPP software was used in data recording. The results of this study indicated that the loop of a 100 cm width has a difference in the temperature of the fluid coming out of the heater and entering the heater that reaches 156,0% higher than the loop of a 50 cm width at the same input voltage. This study is supposed to be one of the references for a single-phase natural circulation loop.

Authors: Oishi Nobuhiro , Yamamoto Naoki , Ishida Akio , Murakami Jun
Published: March 2022

In this paper, structural equation modeling (SEM) is used to analyze the causal relationship between the level of sleep and the environmental data. The data used for the analysis was obtained by a care support device used in an elderly care facility. By applying the stepwise selection method to this data, we were able to find four observation variables that affect the level of sleep. And the latent variables are determined by scree plot. We proposed a causal model in which four observed variables and two latent variables affect the level of sleep. Statistical analysis environment R and the lavaan package were used for SEM analysis in this paper. From this model, it was found that the indoor environment and the vital signs affect sleep, and that heart rate should be reduced to obtain deep sleep.
Identification of Electric Vehicle Charging Stations Using an Optimum Energy Consumption Approach
Authors: Rosa Christian-Anthony , Ramachandran Bhuvaneswari
Published: March 2022

An Electric Vehicle (EV) is a proven solution by car manufacturers to steadily replace the conventional vehicle with a more environmentally friendly option that will reduce our dependence on nonrenewable energies. One drawback is that an EV may take many hours to reach a full charge. Reducing the charging times for EVs are one of the leading challenges for promoting this type of vehicle. Also, the introduction of EVs into the power grid increases flow in the distribution network and as a result increases power flow congestion. Traffic conditions also play a key role in affecting EV battery consumption. Disturbed traffic conditions will result in increased energy consumption of the EV battery and negatively affect the overall performance of EVs. In this research, the problem of scheduling EV battery charging and the assignment of EVs to a Charging Station (CS) is formulated as an optimization problem and will be solved using a simulated annealing optimization method. The assignment of EVs to CSs will satisfy predetermined constraints related to CSs restrictions, the EV conditions, traffic conditions, etc. The proposed approach will be demonstrated using two different scenarios of the system, one where the EVs have homogeneous components and the second, where the EVs have heterogeneous components. From the results, it will be proven that the optimal assignment of an EV occurs when the State of Charge (SoC) of the EV battery remains at its highest possible percentage when arriving at the CS. Keeping the battery SoC at a high percentage results in reduced energy consumption and less charging time.

Authors: Yu Guangming , Zeng Xiankun , Ling Xianzhang , Hao Chuanbo , Wang Kun
Published: March 2022

In the sedimentary coal stratum, rock stratum exhibits layered feature and has an obvious level. Overlying rock often produces separation along the level after the underground coal mining. But, due to the difference in the layers of rocks, the change of the mining process, the difference height in the level and other factors, the rule of separation is extremely complex. Therefore, in this paper, the allometric phenomenon, feature and laws of mining overburden separated strata are found by means of experiment and numerical simulation. The paper reveals the mechanical mechanism of allometric development of overburden separated strata, establishes its development formula based on the theory of beam in the mechanics, analyzing the space-time law of mining subsidence and overburden separation, and finally finds the relationship between surface subsidence and allometric growth of mining overburden separated strata, establishing the subsidence model based on allometric growth of mining overburden separated strata.

Authors: Shah A. J. , Bhaiya Vishisht
Published: March 2022

The coastal population has increased significantly over the past several decades. The increased coastal population led to increased coastal development, which led in turn to great number of structures at risk from coastal hazards. In this study, a G+5 storey reinforced concrete building is analyzed for earthquake and tsunami considering different earthquake zones and different tsunami heights. Based on results, it is found that with the increase in earthquake zone number and tsunami height, values of response quantities of interest i.e. base shear, shear force in column, bending moment and insterstorey drift increases. However, the values of response quantities for tsunami is quite high as compared to earthquake loading.

Authors: Lee Jun-Hyeok , Park Ji-Hong , Kim Seon-Jong
Published: March 2022

This paper proposed a new similarity index for applying to clustering by color-texture using the IOCLBP. We evaluated the relationships of IOCLBP component pairs and investigated a distribution of color-texture properties for apples. And then, we found some correlations between their properties. As selecting the uncorrelated properties and their centric feature vector of apples, the proposed similarity index was introduced as a distance measurer. In experiments of clustering with apple fruits, the results showed that the proposed index has a good performance and is used in color-texture measurer.
Reporting and analysis of Sex and Gender in Transitions of Care for Older Adults: A Methods Study
Authors: Park Hanbyoul , Dewidar Omar , Tanjong-Ghogomu Elizabeth , Welch Vivian
Published: March 2022

Objectives: Sex and gender based analysis may improve understanding of transitions from long term care to community or health services. Our study aims to assess how sex or gender was reported and analyzed in studies about care transitions for older adults.

Methods: We identified longitudinal studies from a 2017 scoping review on factors affecting care transitions of older adults (participants 60 years and older) and assessed transitions from long-term care to community or health services. We used a pretested coding sheet to assess the reporting of sex or gender in 5 sections of the studies: title and abstract, introduction, methods, results, and discussion.

Results: We included 20 longitudinal studies conducted in 3 countries (United States, Germany, and Finland ) with the study durations ranging from less than 1 year to 10 years. Almost all of the studies reported sex distribution of the sample (18/20; 90%). Sex or gender was discussed in the background and rationale by three out of 20 studies (15%). Twelve studies (60%; 12/20) planned to control for sex or gender in their statistical analysis. Association of sex with outcomes was reported by 45% (9/20) and 3 studies (15%; 3/20) provided disaggregated data on sex or gender.

Conclusion: Almost half of the studies assessing transitions from long-term care to community or health services did not control for sex or gender in their statistical analysis. This may be a missed opportunity for understanding potential sex or gender differences in transitions in care for older adults.
The Stigmatization of Schizophrenia
Authors: Ivanova Maria
Published: March 2022

The objective of the following systematic literature review was to analyze the current stigma surrounding schizophrenia in North America, its implications, as well as to suggest potential interventions. The current societal climate reveals that many individuals lack an understanding of the etiology and symptoms of schizophrenia, leading to a general negative bias towards individuals with this disease. Additionally, many misperceptions such as enhanced violent tendencies surround patients with schizophrenia, exacerbating negative bias and actions such as avoidance.  Suggestions to minimize stigma and its effects were made and include the renaming of schizophrenia, the use of virtual reality programs, the refinement of education programs, and an overall switch in how the media presents schizophrenia.

Published: March 2022

Education is an important aspect of human life since it lasts throughout human life. The politeness value must be instilled from an early age in the family, community, and school environment. The phenomenon of the crisis in the value of politeness is a problem that must be resolved. Character education material contained in the National Education Curriculum, especially regarding the value of politeness, should be conveyed through interactive media to facilitate children's learning and understanding, and one of which is through cartoon/animation films. Accordingly, the above reason is the background for research on the Social Character Analysis of Politeness Value in the Nussa and Rara Films. The purpose of this study, in general, is to analyze the politeness values in the animated series Nussa and Rara and their benefits for cultivating the values of politeness in children. The method in this research was through content analysis by discussing in-depth sentences and scenes in animated films in the form of words, sentences, pictures, cut scenes, paragraphs, and so on. There were ten aspects of politeness character based on the analysis of Nussa and Rara, such as (1) Respect for older people; (2) Receiving something always with the right hand; (3) Do not speak dirty and harsh words; (4) Not being arrogant; (5) Dress modestly; (6) Not spitting carelessly;( 7) Appreciating the efforts of others; (8) Respect the opinions of others; (9) Giving, and (10) Do not interrupt in conversation.

Published: March 2022

In recent past conventional monolithic materials are replaced with fiber reinforced polymer composite materials due to their high specific strength. The current study focused on dry-sliding wear behaviour of carbon fiber reinforced polyester (CFRP) composites using a pin-on-disc tribometer. The two output responses selected were rate of wear and frictional force with respect to controlled variables using the Taguchi L16 OA (Orthogonal Array). In order to assess the best optimal conditions GRA technique has been used in the study. The effectiveness of entropy weights on the optimal result has been carried out in support with ANOVA studies. In GRA analysis, the combined effect of wear and frictional force is considered and the optimal conditional identified in two ways namely equal weightage method (EWM) and entropy based weightage method (EBWM). While considering EWM method the optimal condition obtained is S1 L4 D3 R4 whereas in EBWM the optimal solution obtained is S1 L4 D1 R4. This shows because of the uneven weights generated by EBWM method there is a change in optimal solution in comparison with EWM method.

A study was made of the influence of temperature and duration of heat treatment on the formation of diffusion zinc, aluminum and aluminum-zinc coatings. It is shown that at a heat treatment temperature of 400 °C, a three-phase structure in zinc coating is formed. Mutual diffusion occurs on samples with an aluminium-zinc coating with the formation of Al–Zn alloy, samples with an aluminum coating do not undergo structural changes under the studied heat treatment modes. According to the results of corrosion studies it has been revealed that in terms of their properties, mixed aluminum-zinc coatings are closer to the zinc-coated sample than to the aluminum-coated sample.
RANCIÈRE, CRÍTICO DE MARX: IGUALDADE E POLÍTICA

RANCIÈRE, CRITIC OF MARX: EQUALITY AND POLITICS
Authors: Benzaquen Guilherme Fiqueredo
Published: March 2022

Jacques Rancière é um intelectual cuja trajetória está marcada por um debate intenso com os escritos de Karl Marx. Propõe-se, neste artigo, analisar as críticas de Rancière a Marx, particularmente as formuladas desde seu rompimento declarado com o marxismo. A análise é feita, em um primeiro momento, a partir de uma crítica imanente das formulações rancièrianas acerca da igualdade e da política. Em um segundo momento, busca-se sistematizar as críticas do filósofo francês a Marx. Por fim, é realizada uma interpelação entre ambos os autores buscando as aproximações e os distanciamentos. O que se verifica é que a comparação entre Rancière e Marx diz respeito principalmente às suas concepções de igualdade e política. Defende-se, assim, que reforçar o já existente diálogo entre eles contribui para os esforços contemporâneos de promoção da igualdade.AbstractJacques Rancière is an intellectual whose trajectory is marked by an intense debate with the writings of Karl Marx.

Links Between Energy Prices, Fuel Subsidy Reform and Instability
Authors: Price Roz
Published: March 2022

Increasingly, the links between energy insecurity (including energy prices, availability, and fuel subsidy reform) and instability are being studied. These issues often become flashpoints for social mobilisation and protest. Previous research has started to explore different types of fuel-related conflict and its relationship with scarcity, abundance, and energy prices but the research is fragmented. Much of this existing research focuses on a possible link between oil and armed conflict and rebellion, rather than on fuel prices as a source of intra-state instability below the level of armed conflict. It is argued that this research gap is important as these protests often have the potential to escalate into broader political movements, and the pressures to reduce reliance on carbon-heavy fuels through increased taxation or the reduction of subsidies is increasing. This rapid review provides an overview of the evidence on the links between energy prices, subsidy reforms and the risk of instability. It first highlights these links and discusses the literature, and then provides some brief evidence on recommendations and lessons learned on managing the impact of subsidy reform processes. The review was unable to identify any indicators of risk or quantitative metrics for appraising energy-related instability, apart from the unique fuel riots database created by Natalini et al. (2020). This rapid review takes a wide view of “instability” and what that means.
Definitions, Characteristics and Monitoring of Conflict Economies
Authors: Kelly Luke
Published: March 2022

The idea of conflict economies is a broad concept encompassing several research angles. Definitions differ according to these focuses. Some of the main uses of the concept are to understand: • economic analysis of the motives for and likelihood of war • financing of state and non-state belligerents • how the continuation of conflicts can be explained by rational motives including economic ones • how conflict affects economic activity, and how conflict parties and citizens adapt Some distinctive characteristics of war economies are (Ballentine & Nitzschke, 2005, p. 12): • They involve the destruction or circumvention of the formal economy and the growth of informal and black markets, • Pillage, predation, extortion, and deliberate violence against civilians is used by combatants to acquire control over lucrative assets, capture trade networks and diaspora remittances, and exploit labour; • War economies are highly decentralised and privatised, both in the means of coercion and in the means of production and exchange; • Combatants increasingly rely on the licit or illicit exploitation of / trade in lucrative natural resources • They thrive on cross-border trading networks, regional kin and ethnic groups, arms traffickers, and mercenaries, as well as legally operating commercial entities, each of which may have a vested interest in the continuation of conflict and instability. The first section of this rapid review outlines the evolution of the term and key definitions. Most of this discussion occurs in the academic literature around the early 2000s. The second looks at key characteristics of conflict economies identified in the literature, with examples where possible from both academic and grey literature. The third section briefly identifies methodologies used to measure and monitor conflict economies, as well as some current research and programmes on conflict economies, from academic literature as well as NGOs and other sources. The findings have been derived via a literature search and advice from experts in the field. Given time constraints, the report is not comprehensive. The review is gender- and disability blind.
