In Search of Food in a Foreign Destination: The Dining Choice Behaviors of Young Australian Tourists in Japan
Authors: Sugimoto Toyohiko , Nagai Hayato
Published: December 2020

Dining experience is a crucial element in international tourism because it can encourage tourists to understand local culture and has the potential to increase repeat visitation. A better understanding of tourists' dining choice behaviors is important for destination development; however,
the literature has not yet fully investigated this topic, and in particular it is unclear how their behaviors change across repeat visits. This study aimed to fill these gaps by conducting semistructured in-depth interviews with young Australian tourists traveling to Japan. The analysis of
the qualitative data identified four major dining choice patterns: perusing the area, searching online sources, hearing from friends or family members, and calling on previous experience. Within the four patterns, perusing the area (i.e., walking around a food district) was the most observed
behavior for both first-time and repeat tourists. In addition, repeat tourists tended to choose more local and authentic food due to their motivational development from new-and-touristy to local-and-authentic dining experiences. This study's findings extend the current understanding of tourists'
dining choices in the tourism literature and offer suggestions for practitioners.

Published: December 2020

Among the varieties of insects present in mangroves, termites can easily colonize mangrove forests by their winged forms, and thus, build arboreal nests. In view of the presence of this order in mangroves, this work presents the results of a sampling of Termites (Blattaria, Isoptera) in mangrove forests on the Amazon coast, as well as highlighting ecological aspects of these insects. Two collections were carried out during an annual cycle (dry and rainy) at six sampling sites located in the mangroves of Soure on Marajó Island, Pará. In each sampling site, a 100 mx 3 m transection was delimited, subdivided into 10 plots of land. 5 mx 3 m, with an interval of 5 m between each plot, with a sampling effort of 1h / person in each plot in search of termites in the different microhabitats present in the mangrove. A total of seven species distributed in three genera and three families were found over an annual cycle. The most abundant species were Nasutitermes corniger (Motschulsky, 1855) (38.70%), Nasutitermes nigriceps (Haldeman, 1853) (25.00%) and Nasutitermes surinamensis (Holmgren, 1910) (20.16%). The xylophagous termites were dominant and the dry season the number of species and specimens was higher.

Kondo effects in small-bandgap carbon nanotube quantum dots
Authors: Florków Patryk , Krychowski Damian , Lipiński Stanisław
Published: December 2020

We study the magnetoconductance of small-bandgap carbon nanotube quantum dots in the presence of spin–orbit coupling in the strong-correlations regime. A finite-U slave-boson mean-field approach is used to study many-body effects. Different degeneracies are restored in a magnetic field and Kondo effects of different symmetries arise, including SU(3) effects of different types. Full spin–orbital degeneracy might be recovered at zero field and, correspondingly, the SU(4) Kondo effect sets in. We point out the possibility of the occurrence of electron–hole Kondo effects in slanting magnetic fields, which we predict to occur in magnetic fields with an orientation close to perpendicular. When the field approaches a transverse orientation a crossover from SU(2) or SU(3) symmetry into SU(4) is observed.
RESEARCH PECULIARIRIES OF WARHEAD FUSES FOR “KAMIKAZE” TYPE UAVs
Authors: Gordeev S. , Televniy I. , Nikitcnenko V. , Klyufas S. , Skliar V.
Published: December 2020

To defeat surface targets "kamikaze" type UAVs with computer-integrated warheads are used. After preliminary target designation or finding it independently, “kamikaze” type UAV can destroy it, diving on the target as guided ammunition. Defeat characteristics of built-in warhead mainly depend on warhead itself and its fuse.

The results of the combat mission of a UAV type "kamikaze" to hit typical targets are directly affected by the characteristics of the integrated warhead. The characteristics of destructive effect of the integrated warhead mainly depend on its type and explosive device.

To simplify fuse„s characteristics proving process there is sense to divide them on groups, depending on method of their obtainment.

To evaluate common parameters, concerning raw material use, components, proving of technical and economic requirements, correspondence to standardization and unification requirements, ergonomic and esthetic requirements is better to use existing standards and procedures for warhead and fuse evaluation. Laboratory tests prove mainly climatic and mechanical factors resistance. Proving of warhead and fuse effectiveness should be executed on fire range on final stage of "kamikaze" UAV test.

Reliable evaluation results and characteristics are possible after investigation with special laboratory and fire range infrastructure.

At present, the problematic issues of research of integrated warheads explosive devices are the determination of devices expiration service terms and their effectiveness when using UAVs of the "kamikaze" type under utmost permissible operation conditions etc.

“Kamikaze” UAV warhead fuse directly influences on target damage level and should be developed and tested under exacting requirements. Therefore, reliable fuse characteristics, reached during investigation (including fire range test) define whole “kamikaze” UAV effectiveness of operational use.
EFFECTIVE APPLICATION AND PROSPECTS OF IMPROVEMENT OF ANTI-TANK ROCKET COMPLEX MANAGEMENT SYSTEMS
Authors: Moskalets S. , Zhyrnyi V. , Mokrinskyi O. , Rudyk A.
Published: December 2020

Tanks are one of the main means of implementing aggressive plans to capture land territory. To combat tanks and other armored vehicles the projectiles with different types of warheads and anti-tank guided missiles are used. The best means of defeating tanks are anti-tank missile systems (ATMS), which are classified by aiming methods.

The purpose of this work is to review the prospects for development and use of existing ATMS by analyzing the trends of new national and foreign weapons control systems.

Anti-tank missile systems of most advanced world‟s armed forces are, predominantly, second-generation systems with a semi-automatic infrared or laser beam guided systems. Missiles of these systems have a high probability of hitting the target (and penetration of armor) when firing under good visibility conditions. The retrofit of the second- generation systems is being done by increasing the protection against jamming caused to aiming systems due to creating combined infrared and thermal coordinators, improving signal processing methods, and increasing the flight speed of missiles and the reliability of command transmission. The tank engine is a powerful contrasting source of thermal energy.

The main weak links of systems with semi-automatic guidance systems in terms of jamming counteraction are the operator who tracks the target along the missile's flight, and the coordinator of the missile's command aiming that can be “blinded”. Large-scale works on the creation of next generation anti-tank missile systems based on the latest scientific and technological achievements have been considered.

The system‟s operator is one of the weakest links. Careful attitude to the life of every Ukrainian warrior should be a priority, as it is in the modern militaries of the world. This attitude can be ensured by using a reliable missile weapons both natioanl and foreign that would be capable of hitting enemy tanks from a safe distance with a remote control using “fire-and- forget”principle.

Authors: Chupryna V. , Bashynskyi V.
Published: December 2020

The actual problem of the strength properties evaluation of a special armored vehicle "NOVATOR" designed for the transportation of personnel and special cargo is considered. When an armored vehicle roll-over, the strength of the capsule must ensure the preservation of living space for the crew.

To evaluate the strength of the capsule when vehicle rolls-over, in the program Solid Works a spatial model of the fabricated hull of the armored capsule, taking into account the materials of all parts, was developed. Calculations of the stress-strain condition of the capsule and its frame are performed. To analyze the stress-strain condition of the armored vehicle capsule due to static and dynamic loads the finite element method was used, which is implemented in the program SolidWorks Simulation. Simulation of the structural strength by different types of loads was performed in order to adequately evaluate the strength of the capsule.

The results of calculations and simulation of the capsule design showed its insufficient strength, which can lead to significant spatial deformations of the capsule hull and the threat to human life. It does not meet the requirements of UNECE Regulation №66 for motor vehicles to transport people in terms of the strength of their superstructure.

To ensure the required strength of the capsule the analysis of design flaws was performed. The main causes of strength loss and location of critical stresses and strains by sensing the model are identified.

Recommendations were given to the manufacturer to increase the strength of the capsule and provide the necessary safety margin of the structure.

Photoevaporation of Minihalos During Cosmic Reionization: Primordial and Metal-enriched Halos
Authors: Nakatani Riouhei , Fialkov Anastasia , Yoshida Naoki
Published: December 2020

The density distribution of the intergalactic medium is an uncertain but highly important issue in the study of cosmic reionization. It is expected that there are abundant gas clouds hosted by low-mass “minihalos” in the early universe, which act as photon sinks until being photoevaporated by the emerging ultraviolet background (UVB) radiation. We perform a suite of radiation-hydrodynamic simulations to study the photoevaporation of minihalos. Our simulations follow hydrodynamics, nonequilibrium chemistry, and the associated cooling processes in a self-consistent manner. We conduct a parametric study by considering a wide range of gas metallicities (0 Z
⊙ ≤ Z ≤ 10−3
Z
⊙), halo mass (103
M
⊙ ≤ M ≤ 108
M
⊙), UVB intensity (0.01 ≤ J
21 ≤ 1), and turn-on redshift of ionizing sources (10 ≤ z
IN ≤ 20). We show that small halos are evaporated in a few tens of millions of years, whereas larger mass halos survive 10 times longer. The gas mass evolution of a minihalo can be characterized by a scaling parameter that is given by a combination of the halo mass, background radiation intensity, and redshift. Efficient radiative cooling in metal-enriched halos induces fast condensation of the gas to form a dense, self-shielded core. The cold, dense core can become gravitationally unstable in halos with high metallicities. Early metal enrichment may allow star formation in minihalos during cosmic reionization.

Published: December 2020

O presente artigo é um recorte da pesquisa de mestrado desenvolvida no Programa de pós-graduação em Educação em Ciências e Matemática da Universidade Federal de Pernambuco, o trabalho desenvolvido tem como objetivo apresentar a análise sobre a perspectiva de professoras e professores, prioritariamente do Ensino Fundamental, que atuam em escolas da rede pública municipal de Maceió/AL parceiras da Mind Lab na aplicação do Programa MenteInovadora, no sentido de identificarmos se os mesmos têm clareza ou não de como o uso dos jogos enquanto metodologia de ensino podem potencializar o processo de ensino e aprendizagem e favorecer o desenvolvimento de atitudes propícias para aprendizado do seu componente curricular. A partir de uma metodologia de cunho qualitativo, descritiva e de campo, consultamos professoras e professores de diversas áreas do conhecimento na educação básica e constatou-se um esforço por parte destes(as) para a compreensão da importância do papel do jogo no desenvolvimento humano e cognitivo e no equilíbrio psíquico e emocional, tanto nas crianças, como nos adolescentes e jovens; ainda que percebamos uma tendência de vinculação do ato de brincar em sala de aula com a ideia de passatempo, distração. É aludido nas respostas ao questionário aplicado com os(as) docentes, a partir da Análise de Conteúdo em Bardin (2011), que o jogo por si só não garante a aprendizagem, e que o jogo, assim como a brincadeira, deve ser entendido como uma oportunidade de construção de aprendizagem. Nesse contexto, destacaremos aqui, a perspectiva sobre o uso do jogo na educação em autores como Kishimoto (2003 e 2011), Antunes (1998) e Borin (1998).

Authors: Coutinho Cadidja , Ruppenthal Raquel , Baptista Vanessa Dos Anjos , Adaime Martha Bohrer
Published: December 2020

Neste artigo, investigamos ideias que se encontram ao pensar sobre meio ambiente de forma sistêmica e dialógica para a sustentabilidade. Para tanto, o presente trabalho propõe uma ferramenta didática, a mandala ecológica, para identificar as concepções que alguns alunos do Ensino Fundamental têm sobre o meio ambiente. Para constituição dos dados, um grupo de 104 estudantes do Ensino Fundamental de uma escola pública do Noroeste Rio-grandense foi convidado a responder questionamentos relacionados à definição de meio ambiente e sua composição na forma de desenho em espaço delimitado. Para análise das mandalas ecológicas buscou-se identificar as relações existentes entre os diferentes elementos, a concepção sistêmica de meio ambiente (natural, antrópica e/ou mista) que definiu as situações observadas, e a representação de meio ambiente como natureza, território e/ou problema. Além disso, os dados foram submetidos à análise estatística para estabelecer correlações entre as variáveis (idade, sexo, forma de organização, concepção sistêmica e representação de meio ambiente), para verificar o valor de dispersão entre as variáveis e ponderar o grau de associação existente entre as mesmas.Com os resultados obtidos, constatou-se que a maioria dos estudantes compreendeu a proposta de elaboração de desenhos conforme o padrão de mandala; empregou elementos diversificados, principalmente, os que remetem às questões naturais. Da mesma forma, apresentou uma concepção sistêmica predominantemente mista, e a representação de meio como natureza. Foi possível observar que o gênero (feminino e/ou masculino) não influenciou em nenhuma das respostas. Já a idade dos participantes mostrou correspondência significativa para a determinação da concepção sistêmica de meio ambiente. As mandalas ecológicas podem representar uma abordagem didática para a educação ambiental, aliando a realidade social à dimensão ecológica. Essa estratégia de avaliação do perfil ambiental pode auxiliar na construção de cidadãos comprometidos, de forma individual e coletiva, pois permite conhecer as fragilidades para, então, atuar no sentido de saná-las.

Morphology, histology and histochemistry of the digestive tract of the Banded tilapia, Tilapia sparrmanii (Perciformes: Cichlidae)
Authors: Okuthe Grace E. , Bhomela Bongile
Published: December 2020

This study described anatomical, histological and histochemical features of the mucosal layer of the digestive tract of Tilapia sparrmanii Smith, 1840, an omnivorous freshwater fish endemic to Southern Africa. This species exhibited a short thick oesophagus with long deep longitudinal folds (466.68 ± 16.91 µm), and a thick (173.50 ± 10.92 µm) muscular layer that allow the passage of large food items. The mucosa was lined with stratified secretory epithelium rich in goblet cells that secreted neutral and acid mucins. The stomach was a sac-like structure with simple tubular glands surrounded by connective tissue. The mucosa was lined with simple columnar epithelium and the lamina propria exhibited a well-developed layer of gastric glands that occupied the entire length of the cardio-fundic region. The stomach mucosa consisted of epithelial cells with intense neutral mucin secretion which protects against gastric juice. Neck cells of gastric glands synthesized neutral and acid mucins. The intestine was highly coiled and presented a complex pattern of transversal folds internally (villi). Villi length decreased progressively from the anterior to the posterior intestine (p < 0.0001). Tunica muscularis of the mid-intestine had the thinnest thickness among all parts of the intestine (p < 0.0001). Goblet cells whose numbers increased towards the rectum secreted both acid and neutral mucins. The results indicate structural similarities of T. sparrmaniiGIT with other tilapia species and will be useful for understanding the physiology of the digestive systems as well as functional components of the GIT.

A novel coronavirus is the causative agent identified for the current COVID-19 outbreak. Globally, more than 43 million people have been infected by this virus. The total number of deaths has surpassed 1.6 million across 210 countries due to the current pandemic. Till date, there is no specific therapeutic agent available for its treatment. Mpro, a non-structural protein cleaves viral polyproteins into other non-structural proteins. Inhibition of Mpro could prevent the virus replication projecting it as a potential candidate for anti-COVID-19 drug development. The authors report herein 10 top-ranked curcumin derivatives as non-peptide covalent-binding Mpro inhibitors using systematic virtual screening approach. Detailed ligand-receptor interaction analysis conferred that the α,β-unsaturated carbonyl moiety of curcumin functions as a warhead to yield a Michael adduct with Cys145 of the catalytic dyad of Mpro. Collectively, these results have offered new high affinity molecules for the development of potential drugs for the treatment of COVID-19.

This study aims to develop a model from WCVRP by adding characteristics such as split delivery, multiple trips, time windows, heterogeneous fleet, and intermediate facilities alongside an objective function to minimize costs and travel distance. Our model determines the route for transporting waste especially in Cakung District, East Jakarta. The additional characteristics are obtained by analyzing the characteristics of waste transportation in the area. The models are tested using dummy data to analyze the required computational time and route suitability. The models contribute to determining the route of transporting waste afterward. The WCVRP model has been successfully developed, conducted the numerical testing, and implemented with the actual characteristics such as split delivery, multiple trips, time windows, heterogeneous fleets, and intermediate facilities. The output has reached the global optimal for both dummy and real data.

We modeled the stability of SARS-CoV-2 on personal protective equipment (PPE) commonly worn in hospitals when carrying out high-risk airway procedures. Evaluated PPE included the visors and hoods of two brands of commercially available powered air purifying respirators, a disposable face shield, and Tyvek coveralls. Following an exposure to 4.3 log10 plaque-forming units (PFUs) of SARS-CoV-2, all materials displayed a reduction in titer of > 4.2 log10 by 72 hours postexposure, with detectable titers at 72 hours varying by material (1.1–2.3 log10 PFU/mL). Our results highlight the need for proper doffing and disinfection of PPE, or disposal, to reduce the risk of SARS-CoV-2 contact or fomite transmission.

Trong bài báo này chúng tôi nghiên cứu các tính chất phi cổ điển như nén tổng hai mode, nén hiệu hai mode và phản kết chùm bậc cao đơn mode của trạng thái kết hợp điện tích biến dạng chẵn và lẻ. Từ đó, đưa ra các biểu thức giải tích cho cấp độ nén tổng hai mode, nén hiệu hai mode và phản kết chùm bậc cao đơn mode. Kết quả khảo sát chỉ ra rằng trong các trạng thái này xuất hiện quá trình nén tổng hai mode nhưng không có nén hiệu hai mode. Khi nghiên cứu tính chất phản kết chùm bậc cao đơn mode, chúng tôi nhận thấy tính phản kết chùm bậc cao hai mode đều thể hiện khá rõ ràng đối với cả hai trạng thái kết hợp điện tích biến dạng chẵn và lẻ. Cấp độ nén tổng hai mode, cấp độ phản kết chùm bậc cao đơn mode được thể hiện khác nhau thông qua việc chọn các tham số phù hợp, đặc biệt là số điện tích.

Bóng che một phần là một hiện tượng phổ biến làm thay đổi hiệu suất của các hệ thống PV (Photovoltaic). Chúng có thể kể đến như: đám mây, bóng cây, cao ốc…và các điều kiện vận hành phức tạp. Bài viết này với mục tiêu so sánh hiệu suất phát điện của các cấu hình liên kết khác nhau như mắc nối tiếp (SC), mắc song song (PC) hay mắc hỗn hợp (SPC) dưới ảnh hưởng của hiện tượng bóng che một phần. Các cấu hình được đề xuất bao gồm sáu mô đun PV loại 72 tế bào công suất 200W được sử dụng để mô phỏng thông qua phần mềm PSIM. Việc nghiên cứu tập trung vào sự thay đổi đặc tính làm việc của các hệ thống khi thay đổi các yếu tố như: phạm vi bóng che, vị trí bóng che. Các kết quả thu được thông qua mô phỏng đã cho thấy những ảnh hưởng khác nhau đối với các cấu hình khác nhau trong cùng điều kiện vận hành. Nó được giải thích một cách chính xác rằng PC luôn đạt được công suất phát lớn nhất với số điểm phát công suất cực đại ít nhất. mặc dù điện áp ngõ ra của dạng cấu hình này không cao, cái mà có thể gây khó khăn cho việc thiết kế các bộ chuyển đổi DC-DC nhưng lại cho thấy sự ổn định nhất. Điều này có thể được ứng dụng rộng rãi trong việc chọn lựa kiểu cấu hình liên kết sao cho phù hợp với các yêu cầu đặt ra trong các nghiên cứu sau này để đạt được hiệu quả lớn nhất

666
Authors: Miller Daniel
Published: December 2020

The purpose of this augmented lecturing Knowledge Module is to discuss the concept of the numerical figure “six hundred sixty-six” found in the biblical book of Revelation (13:18). It is said to be “the number of the beast”—a monstrous, multi-headed creature of the apocalypse. In the public imagination, “666” has long been associated with two, supposedly interrelated, entities: “the Antichrist” and the biological son of Satan. In the view of biblical scholars, however, these associations are false. Rather, the number 666 is a numerological reference to a first-century Roman emperor who had harshly persecuted those who would come to be known as Christians.
Teachers’ Knowledge and Use of Context Responsive Pedagogy in a Rural Primary School
Authors: Morrison Kadiean
Published: December 2020

This qualitative study reports on the knowledge and usage of context responsive pedagogy (CRP) based on five rural primary school teachers in Jamaica. The main findings revealed that the teachers found CRP beneficial to students, had limited knowledge of CRP, and that their use of CRP was driven by their humanistic beliefs. The findings therefore have implications for teacher professional development. The author recommends that given the benefits of CRP and the strategies required by the National Standards Curriculum (NSC), CRP should be taught to teachers in their pre-service training programme.

This generic qualitative study presents the experiences of four teachers using differentiated instruction in an inner-city Jamaican primary school. The purpose was to ascertain the teachers’ understanding, perception, and the challenges they experienced with the use of differentiated instruction. The data from the four teachers revealed that they had mostly positive perceptions, possessed adequate knowledge and skills in the use of differentiated instruction, and considered it an effective strategy for pedagogy in the 21st century.
Incubators for Extremists? Radicalism and Moderation in Indonesia's Islamic Education System
Authors: Makruf Jamhari
Published: December 2020

Islamic schools and universities in Indonesia have been accused of producing militant Islamist extremists. The Bali bombers, for example, attended ‘hard-line’ (garis keras) schools and a recent spate of book-bombs targeting champions of Islamic moderation were sent by a student at the State Islamic University. But is this perception actually correct? This paper looks at the struggle between moderate and extremist ideas in Indonesia’s madrasahs and Islamic tertiary institutions and its implications for Australian policy. It asks whether Islamic thought in Southeast Asia is becoming more or less radical; whether education in Islamic societies should be reformed to counter extremist ideas; and if so, how.
The 2014 Indonesian Elections and Australia-Indonesia Relations
Authors: McRae Dave
Published: December 2020

Joko Widodo’s election in 2014 as Indonesia’s seventh president reflects a mood of change from Susilo Bambang Yudhoyono’s Indonesia. On the campaign trail, Widodo addressed this mood for change with a populist appeal to voters as a politician who listened to their concerns and would work to make their lives better. His greatest challenges as president come domestically. On this front, he must demonstrate to voters that unpopular decisions such as raising fuel prices are ultimately in their interests. He must also live up to his pledge of a new way of doing politics, despite appointing a cabinet broadly similar in composition to that of his predecessor. Internationally, Jokowi must answer expectations for a more influential Indonesia, but can do so by maintaining substantial continuity in Indonesia’s foreign policy settings. Nevertheless, Australia should not interpret the likelihood of continuity in Indonesia’s international standing and orientation as justifying a status quo approach to bilateral ties.
El impacto de la historia oral en la investigación antropológica: un estudio de caso en la Sierra Norte de Puebla
Authors: Deance Iván
Published: December 2020

La antropología se basa en los métodos y técnicas de investigación etnográfica, los cuales, van desde las entrevistas a profundidad hasta la observación participante. Pese a lo anterior, existen otras herramientas que enriquecen el trabajo antropológico y que provienen de disciplinas diferentes. Este es el caso de la historia oral, sub-disciplina que surge a partir de la recuperación de materiales orales cotejando con fuentes diversas que ayudan a la construcción de un corpus narrativo que contribuye a conocer y comprender el pasado en voz de las personas que lo han vivido. En el presente trabajo se utiliza la historia oral como herramienta para investigación antropológica en el abordaje del conocimiento de la Sierra Norte de Puebla, particularmente en torno a la presa de Necaxa.
La esfera nocturna de la historia: esplendor y miseria de la Ilustración
Authors: Corona Fernández Javier
Published: December 2020

El artículo actualiza el problema que la Escuela de Frankfurt afrontó respecto al análisis de las condiciones que configuran el entorno técnico y natural en las sociedades industrializadas y, con ello, las posibilidades reales para hacer de la vida en la Tierra tanto un infierno de destructividad y desolación como, todo lo contrario. Mas la expectativa de acceder a un estado de humanidad y a un mundo circundante distinto no puede ser factible si se permanece atado a la ideología del progreso. Lo que se requiere es una ruptura en el continuo histórico: rechazar la violencia y pronunciarse a favor de la dignificación del ser humano. La posición de discurso en la que se inscribe este escrito es la teoría crítica de la sociedad, que deduce sus enunciados acerca de las situaciones reales a partir de conceptos universales básicos, pero no sólo en cuanto a su necesidad en sentido lógico, sino a su necesidad concreta. La construcción del acontecer histórico es visto por la teoría crítica como el producto de un mecanismo económico que contiene ya la posibilidad de protestar contra ese orden y, con el despliegue de la subjetividad crítica, permitir que las acciones de los hombres no respondan a un ciego dominio, sino que resulten de sus propias decisiones. Para romper ese dominio inercial y conducirse con autonomía, la humanidad debe poner a la vista y ser consciente de lo que acaece en la esfera nocturna de la historia, caracterizada por la destrucción humana, el hambre, el tráfico de personas, la nueva esclavitud y la auto aniquilación.
