Variação do índice de sinergismo da mistura de Carbaril com butôxido de piperonila em proporções variadas para operárias de abelhas
Authors: De Batista G. C. , Dias E. de A. , Amaral E.
Published: May 2021

Foram conduzidos experimentos de laboratório para investigação da ação sinêrgica do butõxido de piperonila para o carbaril em proporções variadas para operárias híbridas de Apis mellifera ligustica (abelhas italianas) x A.m. adansonii (abelhas africanas).

Após serem anestesiadas com CO2 , as abelhas foram tratadas topicamente no pronoto com soluções acetônicas previamente preparadas, contendo quantidades conhecidas da mistura do inseticida (carbaril) e do sinergista (butóxido de piperonila), com auxílio de uma micro - seringa

adaptada a um micrômetro. Cada mistura, em proporções variadas dos produtos, foi aplicada em pelo menos 6 concentrações diferentes do inseticida (tratamentos), de modo a fornecer mortalidades variáveis de O a100% em 24 horas. Cada tratamento constou de duas repetições, sendo 20 insetos tratados em cada uma destas. Fo i também mantido um tratamento testemunha, no qual os insetos eram tratados com acetona apenas.

Determinou-se, inicialmente, o valor DL 50 para carbaril sõzinho, e a seguir, os valores para as misturas em proporções variadas de 1000: 1, 100:1, 10:1, 5: 1, 1:1, 1:2, 1:5, 1:10, e 1:100 carbaril : butôxido de piperonila , respectivamente . O Índice de sinergismo (I .S.), em cada ca

so, foi calculado tomando-se o quociente entre a DL 50 de carbaril sozinho (numerador) pela DL50 da mistura considerada (denominador).

O Índice de sinergismo aumentou sempre com o aumento da concentração do composto sinergista em relação do composto tóxico , sendo aumentado progressivamente de 1,2 a 3,13 no intervalo testado. Esta tendência crescente do I . S. pode ser explicada pelo bloqueio mais efetivo que maiores concentrações do sinergista causa nos mecanismos destoxificadores do inseto.

Published: May 2021

Embora vários produtos clorados como o DDT e o Toxafeno contra 1cm eficientemente a lagarta rosada do algodoeiro, as recomendações atuais estão restritas aos inseticidas fosforados e carbamatos, dado o curto efeito residual destes.

Dessa maneira, selecionou-se alguns inseticidas dos referidos grupos, formulados a ultra-baixo volume, para realização deste ensaio.

O experimento constou de 7 tratamentos com uma área de 340 m cada um, onde foram efetuadas 3 aplicações espaçadas, de 7 dias.

Antes da primeira aplicação, fez-se uma amostragem em cada área para constatação do seu grau de infestação inicial e o processo adotado consistiu na coleta ao acaso de 50 mas por ares.

Após 7 dias da última aplicação, nova amostragem foi realizada, obedecendo ao mesmo critério anteriormente descrito para constatação do grau de eficiência.

Os inseticidas empregados, dosagens/ha e os resultados obtidos foram: Mexacarbato 18-2. 450 ml - 27,7; Clorpirifos, 24 - 2.147 ml - 60,8; Malatiom 98 - 1.420 ml - 54,7; Fentoato + DDT (15-30) - 2.500 ml- 64,3; Mexacarbato 2E - 2.000 ml - 75,6 e Clorpirifos 4E - 2.548 ml -57,2. A porcentagem de eficiência de cada produto foi obtida através da fórmula de Henderson & Tilton.
Biologia de Perileucoptera coffeella (Guêrin-Mêneville, 1842) (Lepidoptera, Lyonetiidae), em três variedades de café (Coffea spp)
Authors: Nantes J. F. D. , Parra J. R. P.
Published: May 2021

A biologia de Perileucoptera coffeella (Gêurin-Mêneville, 1842) foi estudada em condições de campo nas variedades catuaí, mundo novo e icatu (resistente ferrugem, Hemileia vastatrix, Berk et Br.), durante os meses de verso e inverno.

O ciclo biológico do bicho-mineiro processou-se mais rapidamente na variedade icatu, nas duas pocas estudadas, sendo que na variedade mundo novo, este ciclo apresentou-se mais longo.

As épocas do ano tiveram influência na biologia do bicho-mineiro, sendo que as baixas temperaturas, registradas durante os meses de inverno, atuaram no sentido de diminuir as viabilidades das diferentes fases do ciclo biológico, aumentando a duração total do ciclo da praga.

Luân lý đạo đức Nho giáo nói chung thâm nhập vào đời sống văn hóa Việt không phải chỉ là chuẩn mực đạo đức, hiện thân của đạo lý Nho gia mà còn là hiện thân của đạo lý nhân dân mơ ước, nó tồn tại trong thực tế và được con người Việt Nam bảo vệ. Bài viết từ góc độ liên ngành văn học và văn hóa, cụ thể là từ góc nhìn văn hóa Nho giáo để phân tích nhân vật Thuý Kiều trên các phương diện: Trung, hiếu, tiết, nghĩa. Trung hiếu tiết nghĩa ở Thuý Kiều của Nguyễn Du tất nhiên có phần xuất phát từ lễ giáo Nho gia, nhưng quan trọng hơn cả, đó là lẽ sống giàu lòng yêu thương, giàu nhân nghĩa của con người Việt Nam. Bài viết khẳng định trung hiếu tiết nghĩa ở Thuý Kiều tuy mang tên Nho giáo, nhưng thực chất lại là phẩm chất của con người Việt Nam. Phẩm chất của Thuý Kiều cho thấy đạo đức Nho giáo đã được quan niệm lại do truyền thống của dân tộc, do thực tế của xã hội đương thời và cũng do môi trường sinh sống của bản thân Nguyễn Du. Và điều quan trọng hơn nữa là “đạo đức” ấy lại được nung nấu, thấm nhuần qua một tâm hồn đầy ưu ái, một nhân cách lớn, một nhà nhân đạo cao cả. Bài viết góp phần cho thấy “Truyện Kiều” không đơn giản là tác phẩm vay mượn.

Published: May 2021

We apply gender theory to understand the life of Thuy Kieu at the brothel of Tu Ba in relation to her entire life. We focus on analyzing memories, reflections, and pure love predictions in contrast to the days of exile at Tu Ba's brothel. We identify the levels of spiritual life, emotions, and sexual behaviors in relation to real situations, emotions, psychology, and human values. Expanding our comments, we discuss some opinions of Nguyen Bach Khoa, Ho Dac Duy, and Phan Que in explaining instinctive characteristics, humanity, and social conventions. The reality of action and the ability to self-sense about sexual acts shows the personality, bravery, and cultural depth as well as the rich spiritual world of Thuy Kieu. The article investigates, verifies the reality and the ideal, identifies the multi-personality characteristics of Thuy Kieu from the measure of instinct and individual human qualities, and contributes to affirm the creative talent of the great poet, Nguyen Du.

The geometry of the Rupelian and Chattian depositional bodies in the Lower Rhine district and its border area: implications for Oligocene lithostratigraphy
Authors: Hager H. , Rescher K. , Verstraelen A. , Leroi S. , Bosch M. van den , Abraham A. , Nickel E. , Leeuwen R.J.W. van
Published: May 2021

Three profiles are constructed through the Oligocene succession of the borderland between Belgium, Germany and the Netherlands. The profiles illustrate the geometric relationships between Rupelian and Chattian successions and the lateral and vertical variations within the Rupelian and Chattian deposits.

The end-Rupelian profile between Central Belgium and the Achterhoek area in the Netherlands shows a rather uniform thickness distribution. This is in sharp contrast to the fault controlled sedimentation during the Chattian as represented on an end-Chattian profile between the same areas. Within the Chattian succession several lithostratigraphic units can be identified and correlated using a dense net of geophysical well logs.
Remarkably similar subdivisions are found in the different tectonic blocks, suggesting eustatic sea-level fluctuations. In the central part of the subsiding area the Chattian deposits are largely continental to deltaic. Laterally,these deposits developed into marine glauconitic sediments.
The end-Chattian profile between Bonn and Asten in the Netherlands runs approximately parallel with the subsidence axis. The cyclicity expressed by facies alternations due to a periodically shifting coastline can be correlated over the different blocks again suggesting the involvement of eustatic controls.
On this last profile, an anomalous geometry is due to SE-NW stress-induced movements along the Variscan Aachen overthrust.The three lithological profiles are meant to represent a frame for formal stratigraphic subdivisions and nomenclature.
Tectonic vs climatic control on the sequence development, examples from the Paleogene succession in the eastern North Sea area
Authors: Clausen Ole Rønø
Published: May 2021

A sequence stratigraphic subdivision of the upper Paleocene and the Oligocene is used to exemplify the influence of regional tectonism, local tectonism and climatic changes onto sedimentation in an epicontinental basin.
The analysis shows that the low sedimentation rate and the condensed character of the Paleocene sediments disable any identification of climatic changes, whereas the Oligocene sequence boundaries are controlled by glacio-eustatic sea level changes. Regional tectonism played a major role in generating areas exposed for erosion located east of the present North Sea Basin.
These exposed areas generated sand rich mass flows during the late Paleocene and generated the large amount of sediments which prograded into the Norwegian-Danish Basin during the Oligocene Local tectonics controlled generation of topographic depressions in the western part of the Norwegian-Danish Basin. The subtle depressions controlled the location of the sand rich mass flow deposits both during the late Paleocene and the latest Oligocene.
Triassic lithostratigraphy of the Jameson Land Basin (central East
Greenland), with emphasis on the new Fleming Fjord Group

Published: May 2021

The lithostratigraphy of the Triassic deposits of the Jameson Land Basin in
central East Greenland is revised. The new Scoresby Land Supergroup is now
composed of the Wordie Creek, Pingo Dal, Gipsdalen and Fleming Fjord Groups.
This paper only deals with the lithostratigraphy of the late Early-Late Triassic
continental deposits of the latter three groups with emphasis on the vertebratebearing
Fleming Fjord Group. The new Pingo Dal Group consists of three new
formations, the Rødstaken, Paradigmabjerg and Klitdal Formations (all elevated
from members), the new Gipsdalen Group consists of three new formations,
the Kolledalen, Solfaldsdal (with the new Gråklint Member) and Kap Seaforth
Formations (all elevated from members), and the new Fleming Fjord Group is
subdivided into three new formations, the Edderfugledal, Malmros Klint and
Ørsted Dal Formations (all elevated from members). The Edderfugledal Formation
contains two cyclic bedded, lacustrine members, a lowermost Sporfjeld Member
(elevated from beds), and an uppermost Pingel Dal Member (elevated from beds).
The lacustrine red beds of the Malmros Klint Formation are not subdivided. The
lacustrine and fluvial Ørsted Dal Formation contains three new members. In the
eastern and central part of the basin, the formation is initiated by cyclic bedded,
red lacustrine mudstones of the Carlsberg Fjord Member (elevated from beds),
while in the northwestern part of the basin the lowermost part of the formation
is composed of grey fluvial conglomerates and sandstones with subordinate red
mudstones of the Bjergkronerne Member (elevated from beds). The uppermost part
of the formations in most of the basin is composed of cyclic bedded, variegated
lacustrine mudstones and grey to yellowish marlstones of the Tait Bjerg Member
(elevated from beds). The sediments in the Fleming Fjord Group contain remains
of a rich and diverse vertebrate fauna including dinosaurs, amphibians, turtles,
aeotosaurs, pterosaurs, phytosaurs and mammaliaforms. Most vertebrate bones
have been found in uppermost Malmros Klint Formation, and in the Carlsberg
Fjord and Tait Bjerg Members. The Norian–early Rhaetian, lacustrine Fleming
Fjord Group was deposited at about 41° N on the northern part of the supercontinent
Pangaea. Lacustrine sedimentation was controlled by seasonal as well as
longer-term (orbital) variation in precipitation. Precipitation was probably brought
to the basin by southwesterly winds. The lacustrine sediments of the uppermost
Fleming Fjord Group show deposition during increasingly humid conditions
changing the lake environment from an ephemeral lake-steppe area to a perennial
lake. This evolution of lake environment suggests a change from a winter-wet
temperate climate to one with precipitation throughout the year.
Audience Attitudes towards the Spokesperson of Health Ministries During the COVID-19 Pandemic: A Case Study of Kuwait
Authors: Alqahs Khaled , Alajmi Fawaz
Published: May 2021

This study aimed to identify the attitudes of the Kuwaiti audience towards the performance of the official spokesperson of the Kuwaiti Ministry of Health (MOH), during the COVID-19 pandemic. This study was conducted with a convenience sample consisting of 1201 respondents, of which 52.9% were males and 47.1% were females, with an age range of17-70 years (m=34.78, SD=11.75). The main tool of this study was an electronic questionnaire, that included some demographic variables and self-rating items, such as mass media usage for press conferences and audience motivations to follow the press conferences. It also included the MOH’s official spokesperson’s performance items: the nature of the language, personal characteristics, information presentation, and audience satisfaction. T-test, f-test, chi-square, Pearson correlation, and Scheffe test were used as statistical tools. This study found significant relationships among the audience motivations, the MOH’s official spokesperson’s performance dimensions, and respondents' demographic variables in the intensity of usage of traditional and new media for broadcasting the official spokesperson’s press conferences. This study concluded that there is a need for press conferences, especially during a crisis, in order to fulfil audience motivations and its desire for information about an ongoing crisis, which often makes them focus on social media sites.
Regular and random judgements are not two sides of the same coin: Both representativeness and encoding play a role in randomness perception
Authors: Gronchi Giorgio , Sloman Steven A.
Published: May 2021

The overalternating bias is that people rate sequences with an excess of alternation as more random than prescribed by information theory. There are two main explanations: the representativeness heuristic (Kahneman & Tversky Cognitive Psychology, 3, 430–454, 1972) and the implicit encoding hypothesis (Falk & Konold Psychological Review, 104, 301–318, 1997). These hypotheses are associated with different reaction times predictions. According to the encoding hypothesis, reaction times should increase as the complexity of the sequence increases, whereas the representativeness heuristic predicts fast reaction times only for more complex sequences that appear more random. We asked participants to guess the generating source of pairs of sequences of dichotomous elements in two different conditions: selecting the string generated by a random source or selecting the string generated by a nonrandom source. Results suggest that both the encoding strategy and the representativeness heuristic have a role in randomness perception and that the two criteria may have a different weight when determining the randomness versus the regularity of a string.

Published: May 2021

The United Nations Decade of Education for Sustainable Development, UN/DESD 2005-2014, is reaching its term. The decade was launched with an international footage with the main objective of providing general guidelines that could be readily adapted to a broad audience and diverse learning contexts, so as to further disseminate the concept and rationale of Sustainable Development. Following a bibliographical and documentary review of key journals and conference proceedings, akin to the field of Engineering Education, we present some key figures and trends regarding the introduction of sustainability aspects into engineering degrees within the last 15 years, and review key dissimilarities among the distinct approaches identified. The study reveals a growing number of publications in the field, but a rather small number related to Industrial Engineering Education. Another result relates to the fact that the review rarely found papers that make a reference to the UN/DESD, which surprisingly seems to indicate a poor awareness of such global program.Keywords: Education for Sustainable Development, Sustainable Development, Engineering Education, Industrial Engineering.Estudio del impacto del Decenio de las Naciones Unidas de la Educación para el Desarrollo Sostenible sobre la Educación en Ingeniería IndustrialResumen: El Decenio de las Naciones Unidas de la Educación para el Desarrollo Sostenible, UN/DEDS 2005-2014, está llegando a su fin.

El artículo presenta una revisión bibliográfica en revistas y actas de congresos de la Educación en Ingeniería en los últimos 15 años, observando la introducción de cuestiones de sostenibilidad en los cursos de ingeniería, en particular de la Ingeniería de Organización. El estudio revela un creciente número de publicaciones en el campo, pero, un número muy pequeño se refiere a DEDS, lo que puede indicar que este programa no fue globalmente reconocido y desarrollado.Palabras clave: Educación para el Desarrollo Sostenible, Desarrollo Sostenible, Educación en Ingeniería, Ingeniería Industrial.
The deferral option in the collective dismissal procedure
Authors: Eguren Santos , Solana Pablo , Grijalvo Mercedes
Published: May 2021

The work in this paper focuses on the integration of the real options theory for organizational projects in the management of Human Resources, and particularly on the inclusion of the deferral option in collective dismissal procedures. This option has been studied and developed to be applied to ‘Expediente de regulación de empleo’, which is the legal form existing in Spain for the collective termination of employment contracts and which organizations turn to when confronted with a negative financial situation, as a way of maintaining their viability. Two main issues which it is hoped to resolve are examined: the search for a source of uncertainty to make the deferral option viable for this type of projects, and the development of a procedure to obtain the value of the option and therefore facilitate decision making. The analysis performed has enabled us to state that the volatility of demand is the source of uncertainty that makes the option viable. The procedure developed by the binomial tree, which is determined by the evolution of demand, is the tool that enables the value of the option to be found.Keywords: collective dismissal procedure; deferral option; demand; real options; uncertainty.La opción de aplazamiento en los expedientes de regulación de empleoResumen: El trabajo presentado en este artículo se focaliza en la integración de la teoría de opciones reales en los proyectos organizativos de gestión de Recursos Humanos, en particular en la incorporación de la opción de aplazamiento a los procedimientos de despido colectivo. El estudio y desarrollo de dicha opción se ha llevado a cabo aplicándolo a los Expedientes de Regulación de Empleo, que es la figura legal existente en España para la extinción colectiva de contratos de trabajo y al que las organizaciones recurren ante una situación económica negativa, con el objetivo de mantener su viabilidad. Dos cuestiones principales se acometen y pretenden resolver, la búsqueda de una fuente de incertidumbre que ponga en valor la opción de aplazamiento para este tipo de proyectos y el desarrollo de un procedimiento que permita obtener el valor de la opción y de esta manera facilitar la toma de decisiones. El análisis realizado  ha permitido constatar que la volatilidad de la demanda es la fuente de incertidumbre que pone en valor la opción y la aplicación práctica del procedimiento desarrollado, a partir del árbol binomial que determina la evolución de la demanda, la herramienta que permite obtener el valor de la opción.Palabras clave: expediente de regulación de empleo; opción de aplazamiento; demanda; opciones reales; incertidumbre.

However the market dynamic, effective for most business segments, is defined by the unpredictability and makes the effort of preview very critic. Among the strategies that are possible, the demand management has became as fundamental to the competitively. The purpose of this article is to describe the process of management demand that is adopted by a multinational consumer goods. This company also acts in Brazil. Due to this, the paper proposes suggestions for improvement that are based in the company reality and in the differences between the results which were founded and the theoretical indications about the topic. Therefore, it was used the case study method applied in a subsector of the company. The instruments of the research were interviews, documental analyses and direct observation. The results indicate that the process of management demand, which was used by the company is substantial and well-develop because helps in the achievement of objectives plotted as for the demand forecast and monitoring customer needs and desires. So there is a consistence between literature and practice about demand management that is adopted by the company. The dissonance point which was realized is the absence of a formal and systematized plan of contingency, then dissonance point is a step inside the management model of demand. It is concluded that the company understand the demand management as one of the process that compounds supply chain management. Though the stage “development of systems to contingency management” needs to be improved. The description of this successful process, performed by a large company, can serve as a reference guide for managers of companies that do not adopt the demand management or need to improve the existing.Keywords: Demand management, Supply chain management, Demand management framework, Consumer goods company, Brazilian market.

Colloidal particle aggregation: mechanism of assembly studied via constructal theory modeling
Authors: Bukosky Scott C , Dev Sukrith , Allen Monica S , Allen Jeffery W
Published: May 2021

The assembly of colloidal particles into ordered structures is of great importance to a variety of nanoscale applications where the precise control and placement of particles is essential. A fundamental understanding of this assembly mechanism is necessary to not only predict, but also to tune the desired properties of a given system. Here, we use constructal theory to develop a theoretical model to explain this mechanism with respect to van der Waals and double layer interactions. Preliminary results show that the particle aggregation behavior depends on the initial lattice configuration and solvent properties. Ultimately, our model provides the first constructal framework for predicting the self-assembly of particles and could be expanded upon to fit a range of colloidal systems.

Published: May 2021

The success of community empowerment programs is influenced by efforts to re-interpret the community as an object of empowerment. In traditional Minangkabau, a community is identical to the Kaum, a group of people classified by matrilineal lineage. Solid relationships and cooperation that are part of communal interaction in Kaum significantly are instrumental in fulfilling social and personal needs. This article tries to answer a fundamental question of how social networks of economic welfare based on the Kaum as a model of empowering Islamic society. To answer this question, the inductive logic of multiple case designs is used by taking five (5) Kaum in Nagari Tabek Patah as the locus of the study. This case study used NVIVO in the data processing. This research reveals that kaum social networks are formed naturally in the community, strengthened by customary norms and laws, and become a controller in realizing economic welfare.

Published: May 2021

Academically talented students are students who have above average abilities, particularly in the academic since birth, and can develop through a process of training. As their ability to process learning and information is faster than the average students, they are prone to feel frustrated if they are treated the same as the average students. Hence, this study analyzes the content and learning process in-depth required by these academically talented students. The analysis document through the embedded multiple-case design was used for data collection in this study. The data were analyzed qualitatively using NVIVO 12.0 software. The results of the analysis showed that the learning content for academically talented students are; (i) content based on current issues, (ii) significant content, (iii) challenging content, (iv) advanced content, (v) inspiring content), (vi) thematic-integrative, (vii) critical knowledge and experience construction content-based, and (viii) controversial content issue and active debate. While the learning process for academically talented students are; (i) independent study, (ii) problem solving, (iii) criticism learning, (iv) effective learning, (v) inspired learning, (vi) higher-order thinking learning (HOTs), (vii) guesswork learning), (viii) inquiry learning, (ix) possibility learning, (x) exploring learning, (xi) flexibility learning), (xii) straight learning, and (xiii) giving students liberty (learner-centered). Considering the results of this study, to develop the ability of academically talented students to the maximum, behavioristic and constructivist learning and a varied combination of both can be applied.
A Large Scalar Multiplication Algorithm using Modified Pell Numbers for Key Generation
Authors: Duemong Fudailah , Preechaveerakul Ladda
Published: May 2021

Cryptographic algorithms consist of two parts, a key and an algorithm, to encrypt and decrypt data. The key is an essential part that works with the algorithm. The security of encryption schemes depends on the key size (key length) and the longer the key, the better the security it provides. Applying an elliptic curve has for key agreement provides a high-performance architecture and high security. The main process for calculating key points in Elliptic Curve Cryptography (ECC) is called scalar multiplication, which relates to point addition and point doubling. An efficient algorithm, proposed as the Large Scalar Multiplication Algorithm using Modified Pell Numbers (LSMA-MPN), was introduced to speed up the calculation of points on elliptic curves during large scalar multiplications. This system also reduced computation time by applying Modified Pell numbers in a 22 matrix representation. The experimental results showed that computation time was reduced by approximately 67% in comparison with the computation time required by a general algorithm.
Entwining Thomistic and Anselmian Interpretations of the Atonement
Authors: Thurow Joshua , Strabbing Jada Twedt
Published: May 2021

In Atonement, Eleonore Stump develops a novel and compelling Thomistic account of the atonement and argues that Anselmian interpretations must be rejected. In this review essay, after summarizing her account, we raise worries about some aspects of it. First, we respond to her primary objection to Anselmian interpretations by arguing that, contrary to Stump, love does not require unilateral and unconditional forgiveness. Second, we suggest that the heart of Anselmian interpretations—that reconciliation with God requires reparation/restitution/satisfaction—is plausible and well-supported by some of her own arguments. Third, we raise doubts about her views of the role of surrender in justification and the nature of justification itself. Finally, we question whether Stump’s account can successfully explain how the atonement deals with pre-justification sin. A central theme of our comments is that Stump’s Thomistic interpretation can be entwined with Anselmian interpretations to make a stronger account of the atonement.

Numa escola onde não existem "atividades de aprendizagem", apenas "aula, prova e repasse", podemos ter a disciplina mais férrea do mundo, e não vamos além do treinamento domesticador. Colocar os alunos para marchar é fútil, também porque não tem importância para a formação deles. Mas cuidar que a escola tenha ambiente de civilidade bem curtida, de interações  respeitosas e colaborativas, de relacionamentos edificantes entre professores e alunos, de participação familiar e comunitária elevada, só faz bem. Também de modismos podemos aprender alguma coisa, mas são ventos que passam ao lado, por vezes distantes, desviando a atenção para o que mais dói na escola: ficar nela 12 anos e sair quase analfabeto, como é o caso em matemática: em  2017, apenas 4.52% dos estudantes do ensino médio aprenderam (Saeb, 2018). Para aprender, em especial aprender como autor (Demo, 2015), é importante que a escola tenha disciplina, não doutrine os estudantes, cultive a civilidade, mas principalmente precisa garantir o direito de aprender, que hoje está em pandarecos.
ENSAIO APRENDER COMO AUTOR NA EDUCAÇAO INFANTIL E ENSINO FUNDAMENTAL

Para aprender, o estudante precisa exercitar “atividades de aprendizagem” (Demo, 2018; 2018a), como ler, estudar, elaborar, pesquisar, fundamentar, todas autorais, não instrucionistas. Aprendizagem não provém de aula, porque esta é mediação externa, não sendo possível “causar”, de fora, de cima, a aprendizagem do estudante. Papel do professor é organizar tais atividades em projetos longos de pesquisa, nos quais aulas de 45 minutos não fazem qualquer sentido. Escola realmente voltada para a aprendizagem do estudante tem formato completamente diverso, não é um monte de salas de aula, mas uma comunidade de aprendizagem dedicada a garantir ao estudante o direito de aprender como autor (Demo, 2015).

Through this article we will be presenting an innovative technique to hold the distalized position of molars using mini implants. This simple but effective method has proved to be useful to hold the distalized position of molars. Keywords: Distalization; mini implants
Investigation of Smart Tools in Order to Improve the Effectiveness of the Administration of Disaster Management I.
Authors: Lakatos Bence
Published: May 2021

The security of a well-functioning country requires an administrative and defence management system. The author presents the operation and activity system of the Hungarian disaster management organizational system, paying special attention to the examination of smart devices that improve the efficiency of public administration. The author demonstrates in his research that the use of smart devices and technologies contributes to the reduction of disaster risk, damage, and helps disaster prevention. Based on the applied research methods, the author proves that due to the identified problems, the increasing number of inspections and the growing information society expectations require us to use the tools and technologies of disaster management authorities to strengthen the safety factors.
THE EFFECTS OF PARK IMPROVEMENT ON PARK USE AND PARK-BASED PHYSICAL ACTIVITY

Park is considered as one of the necessary settings in the urban area to promote physical activity and a healthy lifestyle. It provides opportunities to engage in park-based physical activity to a wide range of users. Studies have found that park improvement is a sustainable way to increase the urban population’s physical activity levels. This study explores the effects of park improvement on park use and park-base physical activity using Benjakitti Park, one of the major district parks in Bangkok, Thailand, as the case study. The park improvement was designed and constructed from October 2016 – January 2017. A System for Observing Play and Recreation in Communities (SOPARC) observations were used to observe the changes in park use and park-based physical activity before and after the park improvement. It was found that park improvement changed users’ characteristics and the patterns of park use and park-based physical activity. The park improvement was associated with an increasing number of children and elderly visitors and a 4.1% and 17.6% increase in cycling and running. The project shows that even a tiny improvement in the built environment can change people’s attitude and behaviour towards physical activity and a healthy lifestyle.

The updated H-band spectral-line list (from λ15000–17000) adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) for the SDSS-IV Data Release 16 (DR16) is presented in this work. The APOGEE line list is a combination of atomic and molecular lines, with data drawn from laboratory, theoretical, and astrophysical sources. Oscillator strengths and damping constants are adjusted using high signal-to-noise, high-resolution spectra of the Sun, and α Boo (Arcturus), as “standard stars.” Updates to the DR16 line list, as compared to the previous DR14 version, include the addition of molecular H2O and FeH lines, as well as a much larger (by a factor of ∼4) atomic line list, including a significantly greater number of transitions with hyperfine splitting. More recent references and line lists for the crucial molecules, CO and OH, as well as for C2 and SiH, are also included. In contrast to DR14, DR16 contains measurable lines from the heavy neutron-capture elements cerium (as Ce ii), neodymium (as Nd ii), and ytterbium (as Yb ii), as well as one line from rubidium (as Rb i), which may be detectable in a small fraction of APOGEE red giants.

We show how spectra of Type Ia supernovae (SNe Ia) at maximum light can be used to improve cosmological distance estimates. In a companion article, we used manifold learning to build a three-dimensional parameterization of the intrinsic diversity of SNe Ia at maximum light that we call the “Twins Embedding.” In this article, we discuss how the Twins Embedding can be used to improve the standardization of SNe Ia. With a single spectrophotometrically calibrated spectrum near maximum light, we can standardize our sample of SNe Ia with an rms of 0.101 ± 0.007 mag, which corresponds to 0.084 ± 0.009 mag if peculiar velocity contributions are removed and to 0.073 ± 0.008 mag if a larger reference sample were obtained. Our techniques can standardize the full range of SNe Ia, including those typically labeled as peculiar and often rejected from other analyses. We find that traditional light-curve width + color standardization such as SALT2 is not sufficient. The Twins Embedding identifies a subset of SNe Ia, including, but not limited to, 91T-like SNe Ia whose SALT2 distance estimates are biased by 0.229 ± 0.045 mag. Standardization using the Twins Embedding also significantly decreases host-galaxy correlations. We recover a host mass step of 0.040 ± 0.020 mag compared to 0.092 ± 0.026 mag for SALT2 standardization on the same sample of SNe Ia. These biases in traditional standardization methods could significantly impact future cosmology analyses if not properly taken into account.

Recent 1D core-collapse simulations indicate a nonmonotonicity of the explodability of massive stars with respect to their precollapse core masses, which is in contrast to commonly used prescriptions. In this work, we explore the implications of these results on the formation of coalescing black hole (BH)–neutron star (NS) binaries. Furthermore, we investigate the effects of natal kicks and the NS’s radius on the synthesis of such systems and potential electromagnetic counterparts (EMCs) linked to them. Models based on 1D core-collapse simulations result in a BH–NS merger detection rate ( ∼ 2.3 yr−1), 5–10 times larger than the predictions of “standard” prescriptions. This is primarily due to the formation of low-mass BHs via direct collapse, and hence no natal kicks, favored by the 1D simulations. The fraction of observed systems that will produce an EMC, with the supernova engine from 1D simulations, ranges from 2% to 25%, depending on the NS equation of state. Notably, in most merging systems with EMCs, the NS is the first-born compact object, as long as the NS’s radius is ≲ 12 km. Furthermore, models with negligible kicks for low-mass BHs increase the detection rate of GW190426_152155-like events to ∼ 0.6 yr−1, with an associated probability of EMC ≤10% for all supernova engines. Finally, models based on 1D core-collapse simulations predict a ratio of BH–NSs to binary BHs’ merger rate density that is at least twice as high as other prescriptions, but at the same time overpredicting the measured local merger density rate of binary black holes.

We use new Hubble Space Telescope (HST) images of nine Green Pea galaxies (GPGs) to study their resolved structure and color. The choice of filters, F555W and F850LP, together with the redshift of the galaxies (z ∼ 0.25), minimizes the contribution of the nebular [O iii] and Hα emission lines to the broadband images. While these galaxies are typically very blue in color, our analysis reveals that it is only the dominant stellar clusters that are blue. Each GPG does clearly show the presence of at least one bright and compact star-forming region, but these are invariably superimposed on a more extended and lower surface brightness emission. Moreover, the colors of the star-forming regions are on average bluer than those of the diffuse emission, reaching up to 0.6 magnitudes bluer. Assuming that the diffuse and compact components have constant and single-burst star formation histories, respectively, the observed colors imply that the diffuse components (possibly the host galaxy of the star formation episode) have, on average, old stellar ages (>1 Gyr), while the star clusters are younger than 500 Myr. While a redder stellar component is perhaps the most plausible explanation for these results, the limitations of our current data set lead us to examine possible alternative mechanisms, particularly recombination emission processes, which are unusually prominent in systems with such strong line emission. With the available data, however, it is not possible to distinguish between these two interpretations. A substantial presence of old stars would indicate that the mechanisms allowing large escape fractions in these local galaxies may be different from those at play during the reionization epoch.
