Bolchevismo ou maximalismo: uma abordagem terminológica e diacrônica
Authors: Conceição Fabiana Zogbi Lontra da
Published: September 2020

Este trabalho tem como objetivo descrever e analisar o emprego do termo bolchevismo e de suas variantes no momento de sua introdução e início de sua circulação no Brasil (1917-1920). Para tanto, adotamos a ótica da Terminologia Diacrônica em conjunto com a Socioterminologia Variacionista. Utilizamos como fonte os registros jornalísticos reunidos em O Ano Vermelho (MONIZ BANDEIRA; MELO; ANDRADE, 1980) e o acervo de jornais da Hemeroteca Digital Brasileira com o intuito de verificar em que categorias de variantes do constructo de Faulstich (2001) os termos se inserem. Através da análise das variantes, concluímos que a variação, de ordem competitiva, foi suprimida pela necessidade de definição do conceito, o que levou à consagração do termo bolchevismo.

Authors: Souza Adriano de , Geribone Viviane De Vargas
Published: September 2020

Este artigo aborda o tema da leitura, apresentando e discutindo a relevância de um modelo sociocognitivo de negociação de sentidos. Para tanto, analisamos a questão da leitura no documento Base Nacional Comum Curricular (BNCC), com foco nas habilidades do componente Língua Portuguesa (LP), da seção Ensino Médio (EM). Utilizamos uma abordagem metodológica de cunho interpretativista e desenvolvemos alguns pressupostos teóricos implicados na noção de leitura como negociação de sentidos. Apresentamos duas premissas para negociação de sentidos em práticas de leitura, a saber, confrontação interativa e concertação participante. A análise da BNCC revelou a presença de dois tipos de habilidades, sendo um conjunto mais afeito às práticas horizontais de negociação de sentidos e outro menos alinhado a essa finalidade.

Human resource management in public-private partnership organisations: A review
Authors: Onyoin Moses
Published: September 2020

The proliferating phenomenon of public-private partnership (PPP) in public service provision continues to lay a firm foundation for the growth of organizations of hybrid character (van Gestel, Denis, & Ferlie, 2020). Unfortunately, the effects of such organizational arrangements on critical management practices remain underexplored (Berman, 2012). Analytically focusing on purpose-based taxonomy of practices including hiring, training, compensation, and employment relations (Chuang, Chen, & Chuang, 2013), this paper theoretically explores the possible implications of the PPP modality on human resource management (HRM) practice at the organizational level. Thirteen (13) critical propositions are delineated from interpretively intersecting extant knowledge from PPP and HRM strands of literature. In essence, the analysis suggests a) the high dependence of HRM practice and decision-making on the structural and institutional context, b) the necessity for more agility, characterized by adaptability and dynamism, and c) the need for a changed management competence profile of practitioners focusing on strategic and integrative skills sets in a PPP organization context. The paper advances the propositions as important insights for practitioners and as potent directions for further research.
Modelling of initial deposition of biomass ash particles on walls of superheater tubes
Authors: Wang Yibin , Liu Hexin , Tan Houzhang
Published: September 2020

Condensation of gaseous alkali chloride and sulphate and adhesion of molten ash particles are still an important issue of investigation and gaining more and more attention in biomass utilization. In this work the behaviours for formation of initial deposition layer and condensation of KCl(g) and K2SO4(g) were simulated nu-merically in a 2-D computational domain of an in-line 4?4 tube bundle. The sticking and rebound efficiency of incident particles, condensation rate of gaseous salts and ash deposition rate on both of the windward and the leeward sides of tubes were obtained through transient calculation cases. The ash deposition mass on the windward side of tubes is mainly from impaction and stickiness of large ash particles. The condensation rate of KCl(g) is two orders of magnitude higher than that of K2SO4(g) on both of the windward and the leeward side of tubes. The ash deposition rate and the condensation rate on the windward side of tubes are of equal importance. While on the leeward side of tubes the condensation of salt vapours is more dominant than the inertial impaction in the forming stage of initial layer.
Effects of temperature and additives on ash transformation and melting of high-alkali-chlorine coal
Authors: Zi Jingbin , Ma Daoyang , Rahman Zia , Wang Xuebin , Li Hao , Liao Shengming
Published: September 2020

The high contents of sodium and chlorine in Shaerhu coal aggravate severe slag-ging ash deposition and corrosion in boilers. Adding proper additives is an effec-tive way to reduce slagging ash deposition and corrosion. Based on the experi-mental study, this paper investigated the effect of combustion temperature, types of additives, and its amount on the ash transformation and melting of high sodium chloride Shaerhu coal. The ash melting characteristics, elemental compositions and mineral compositions of the ash produced under different conditions were characterized. Results showed that the contents of calcium, magnesium, and sul-phur in the coal ash varied slightly with the temperature increasing. Chlorine and sodium released rapidly from coal at 550-815?C and 550-700?C, respectively. At 1050?C, calcium silicate was observed as the main component of the ash. The addition of different additives had no significant effect on chlorine and sodium capture. The addition of silicon species lowered the ash fusion temperatures, while the aluminum had an opposite effect. To prevent the furnace from slagging, a high aluminum additive is proposed to be adopted.
Numerical study on ladle baking process of oxy-fuel combustion
Authors: Qi Fengsheng , Shan Jianbiao , Li Baokuan , Baleta Jakov
Published: September 2020

Ladle baking technology is a widely adopted method in the iron and steel industry. For reducing defects such as centre segregation of billet, it is crucial to minimize the heat loss of molten steel; maintaining a high drawing speed and low superheat during the continuous casting process. Nevertheless, it is well known that the traditional air combustion ladle baking technology suffers from high energy consumption and severe pollution problems. On the other hand, the oxy-fuel combustion technology where fuel combustion is supported by pure oxygen offers many attractive advantages, including high theoretical combustion temperature, low flue gas emission, and enhanced heat transfer of gas radiation. Unfortunately, up to date, limited researches have been carried to understand the potential of the technology. In the present study, a 3-D mathematical model has been established considering the details of turbulent combustion behaviour and its coupling effects on the heat transfer phenomenon during ladle baking process. Considering the difference between gas radiation in oxygen-enriched combustion and the traditional air-assisted combustion, a modified weighted sum of gray gases model were introduced and compared with the conventional model. Based on the established mathematical model, the operation efficiency of the oxy-fuel combustion and air combustion technologies were studied in details. Numerical results show that the oxy-fuel combustion is more efficient and achieves a potential fuel savings of 41.6%.
Improving energy efficiency of kindergartens in Serbia: Challenges and potentials
Authors: Cukovic-Ignjatovic Natasa , Ignjatovic Dusan , Zekovic Bojana
Published: September 2020

Kindergartens are probably the very first public buildings we actively use in our lives. Therefore, they can be considered as the physical structures that are providing for the very important educational and social function. Additionally, they can also be considered as the specific learning tool for future generations where they can encounter the ideas of green and energy-efficient buildings. One of the results of the research project ?Energy efficiency in public buildings? has been formulated through the development of Serbian National Typology of Kindergartens which was conceived as a specific tool that can be used for improving this portion of building stock. The paper presents the methodology for identification of typical kindergarten buildings, covering various construction periods, building sizes and illustrates the type of analysis performed for model representatives. The potential for energy upgrades covering physical structure, installed technological systems, as well as expected impact on energy performance, has been estimated. The study presents results based on the analysis of the data derived from the National Typology, stressing out that energy retrofits of large and medium-sized kindergartens built during the 1970s and 1980s should be the primary focus of refurbishment activities. Accounting for almost 60% of total buildings and 69.59% of heated area, they are responsible for 75.97% of energy demands. Estimated energy savings of more than 60% indicate the effectiveness of their retrofit. The paper also presents the potential uses of National Typology as a retrofit tool on various scales, from single-building considerations to a strategic approach at the national level.

Authors: Rosato Antonio , Ciervo Antonio , Guarino Francesco , Ciampi Giovanni , Scorpio Michelangelo , Sibilio Sergio
Published: September 2020

A centralized solar hybrid heating and cooling system satisfying the thermal, cooling and sanitary water demands of a typical Italian small district composed of six residential buildings situated in Naples (southern Italy) is modelled, simulated and analysed through the software TRNSYS over a period of 5 years. The plant is based on the operation of solar thermal collectors coupled with seasonal borehole storage; the solar field is also composed of photovoltaic solar panels connected with electric energy storage. An adsorption chiller powered by solar energy is adopted for cooling purposes, while a condensing boiler is used as an auxiliary unit. The performance of the proposed system has been assessed from energy, environmental and economic points of view and contrasted with the operation of a typical Italian heating and cooling plant, highlighting the following main results: saving of primary energy consumption up to 40.2%; (decrease of equivalent CO2 emissions up to 38.4%; reduction of operating costs up to 40.1%; and simple pay-back period of about 20 years.
Feasibility analysis of a combined chemical looping combustion and renewable-energy-based methane production system for CO2 capture and utilization
Authors: Bareschino Piero , Mancusi Erasmo , Pepe Francesco , Urciuolo Massimo , Coppola Antonio
Published: September 2020

Power-to-methane represents an innovative approach to convert electrical into chemical energy. Such a technology could actually be successful only when the coupling of a cost-effective source of electrical energy and a pure CO2 stream is carried out. Under this perspective, this paper numerically investigates an inno-vative process layout that integrates a fluidized beds chemical looping system for the combustion of solid fuels and a renewable-based power-to-methane system. Process performances were evaluated by considering a coal and three sewage sludge, differing in water content, as fuels, CuO supported on zirconia as oxygen carrier, hydrogen production via water electrolysis, and Ni supported on alumina as methanation catalyst. Autothermal feasibility of the process was assessed by considering that part of the produced CH4 can eventually be burned to dry high-moisture-content fuels. Finally, by considering that only electric energy from renewable sources is used, the capability of the proposed process to be used as an energy storage system was evaluated.
Excess heat utilization combined with thermal storage integration in district heating systems using renewables
Authors: Doracic Borna , Grozdek Marino , Puksec Tomislav , Duic Neven
Published: September 2020

District heating systems already play an important role in increasing the sustainability of the heating sector and decreasing its environmental impact. However, a high share of these systems is old and inefficient and therefore needs to change towards the 4th generation district heating, which will incorporate various energy sources, including renewables and excess heat of different origins. Especially excess heat from industrial and service sector facilities is an interesting source since its potential has already been proven to be highly significant, with some researches showing that it could cover the heat demand of the entire residential and service sector in Europe. However, most analyses of its utilisation in district heating are not done on the hourly level, therefore not taking into account the variability of its availability. For that reason, the main goal of this work was to analyse the integration of industrial excess heat into the district heating system consisting of different configurations, including the zero fuel cost technologies like solar thermal. Furthermore, cogeneration units were a part of every simulated configuration, providing the link to the power sector. Excess heat was shown to decrease the operation of peak load boiler and cogeneration, that way decreasing the costs and environmental effect of the system. However, since its hourly availability differs from the heat demand, thermal storage needs to be implemented in order to increase the utilisation of this source. The analysis was performed on the hourly level in the energyPRO software

Multiple intelligences are the development of intelligence of the brain or intelligence quotient (IQ), emotional intelligence or emotional quotient (EQ), and spiritual intelligence or Spiritual Quotient (SQ). The intelligence consists of nine levels of intelligence is known as the Multiple Intelligences (MI) which includes: linguistic intelligence, mathematical-logical intelligence, visual spatial intelligence, physical-kinesthetic intelligence, musical intelligence, interpersonal intelligence, intrapersonal intelligence, naturalist intelligence, and existential lntelligence. This theory shows that there is no human activity that uses only one intelligence, but uses all intelligence that exists in humans. Intelligence is a single talent that students use in situations of solving any problem. Every student has a different intelligence. This is because there are several factors that influence it, namely the hereditary factor, interest factor, formation factor, maturity factor, and freedom factor.This research are descriptive study which aims to reveal the level of MI of social sciences and linguistcs student grade X crossing biology interest at SMAN 1V Koto KampungDalam. Results of the study, it was faund that the most dominant intelligence in social science students is naturalist intelligence. In the linguistics scienscestudents, the most dominant intelligence is existential intelligence.
Island territorial disputes and China’s ‘Shelving Disputes and Pursuing Joint Development’ policy
Authors: Yu Tao , Li Bingyao
Published: September 2020

‘Shelving Disputes and Pursuing Joint Development’ (SDPJD) has for decades been China’s premier policy for resolving territorial disputes, especially those regarding islands. SDPJD is, however, commonly understood to be tripartite policy, in which ‘shelving disputes’ and ‘pursuing joint development’ are made conditional upon the principle of ‘sovereignty belongs to China’. Although SDPJD aims to peacefully settle China’s island territorial disputes in the East China Sea (Diaoyu Islands) and the South China Sea (Spratly Islands), the policy has not been particularly successful in practice. This is in part because, whereas ‘shelving disputes’ and ‘pursuing joint development’ are cooperative in nature, ‘sovereignty belongs to China’ is inherently confrontational. The prominence granted to ‘sovereignty belongs to China’ is linked to outmoded understanding of the concept of sovereignty and the tendency for Chinese scholars and officials to regard island territorial disputes as the zero-sum games. This paper argues that SDPJD’s success is dependent upon separating ‘sovereignty belongs to China’ from ‘shelving disputes’ and ‘pursuing joint development’ and perhaps abandoning the former principle entirely. China should pursue non-confrontation resolution to island territorial pursuits, especially in the contexts of efforts to develop a peaceful and cooperative 21st-Century Maritime Silk Road.
Cognitive and Ethical Bases of Discourse and Discourse Analysis

The definitions of discourse are varied, bearing both philosophical and philological features. Discourse is a means to establish social relationships as well as their result. Discourse analysis (including its varieties) presents new empirical opportunities for scholars, who are seeking understanding of social reality. Discourse analysis is a complex method that has a potential to be applied to various studies: sociology, political theory, philosophy, linguistics, cultural studies, history, etc. The capacity of discourse to constitute everyday life gives us an opportunity to interpret social reality, our experiences and meanings that are created within it. In social-constructionist epistemology the major role is given to these two perspectives: cognitive (where discourse is viewed as a mental phenomenon, represented in texts) and ethical (where discourse is viewed as a condition for social action). These are the aspects of understanding of discourse and the methods for its examination.

One of the key functions of the professional educational environment of the university is to satisfy the need for social orientation of each member of the educational and professional community (group, course, creative association). The person who is integrated into the new social conditions is faced with the task of forming ideas about the profession, about the image of a professional, about a model for mastering professional competencies. In this regard, the social environment and the nature of relations in it are of great importance. The carrier of social environment determinants is a social group that has a system of values, standards of behavior, attitudes that will not be equally significant for each member of the group – group reference characteristics are refracted through the prism of personal choice, the experience of each member of the group, who has mastered patterns of behavior and interaction. Each social group has a certain degree of reference. The article analyzes the types of intragroup reference based on a combination of indicators of group cohesion and the type of interpersonal behavior, predicts the dynamics of the development of relations in a group with one or another type of reference and describes the effect of each type on the effectiveness of educational and professional activities.

Penggunaan obat antibiotik sintetis semakin marak digunakan. Cara alternatif yang bisa dilakukan ialah dengan memanfaatkan tanaman bintaro (Cerbera odollam) dan mimba (Azadirachta indica A. Juss) yang diketahui berpotensi sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui profil fitokimia ekstrak daun bintaro dan mimba secara kualitatif dan mengetahui pengaruh kombinasi ekstrak kedua daun terhadap pertumbuhan bakteri Escherichia coli FNCC 0091. Ekstraksi dilakukan dengan cara maserasi menggunakan pelarut etanol 96%. Pengujian efektivitas antibakteri dilakukan dengan metode difusi agar dengan cara pour plate dan menggunakan amoxycillin sebagai kontrol positif serta akuades sebagai kontrol negatif. Metode penelitian yang digunakan ialah RAL dengan ANOVA satu arah dilanjutkan dengan uji Duncan. Penelitian ini menggunakan 4 perlakuan konsentrasi yaitu 10%, 20%, 40% dan 80%. Hasil uji profil fitokimia menunjukkan bahwa ekstrak daun bintaro dan mimba mengandung alkaloid, flavonoid, saponin, steroid, triterpenoid, tanin dan fenolik. Data yang diperoleh berupa rata-rata diameter zona hambat. Pada perlakuan aktivitas antibakteri kombinasi ekstrak daun bintaro dan mimba terhadap pertumbuhan bakteri E. coli diperoleh rata-rata diameter zona hambat sebesar 14,58 ± 0,87 mm pada perlakuan kontrol positif, pada perlakuan kombinasi ekstrak daun bintaro dan mimba dengan konsentrasi yang terkecil hingga konsentrasi terbesar yaitu sebesar 2,00 ± 0,25 mm; 3,41 ± 0,38; 4,08 ± 0,14 mm; dan 5,25 ± 0,25 mm. Kontrol negatif (akuades) tidak mampu menghambat pertumbuhan bakteri E. coli.Berdasarkan hasil tersebut diketahui bahwa semakin tinggi konsentrasi zat antibakteri yang diberikan maka semakin besar zona hambat yang terbentuk. Kombinasi ekstrak daun bintaro dan mimba yang efektif dalam menghambat pertumbuhan dari bakteri adalah konsentrasi 80%.
Formación y uso de conventos en la provincia franciscana de Michoacán durante el virreinato
Authors: Martínez Aguilar José Manuel
Published: September 2020

Durante la época virreinal, los franciscanos desarrollaron una importante labor de evangelización, adoctrinamiento y administración de sacramentos en numerosas localidades de la Nueva España. Durante este proceso de larga duración, hicieron levantar una serie de conventos, templos y capillas, desde donde atendían a los pueblos a su cargo. Con base en el análisis de crónicas franciscanas, manuscritos de archivo, bibliografía especializada y en la observación de los vestigios materiales, se proponen en este trabajo cinco etapas que dan cuenta de la formación y uso de los edificios religiosos administrados por la orden de San Francisco en la provincia de San Pedro y San Pablo de Michoacán durante la época virreinal: 1) Incursión y penetración, 2) Expansión, 3) Reconstrucción, 4) Ampliación y mejoramiento, y 5) Secularización y nuevas misiones.
Bajo la máscara de la “revuelta ixtepejana”. Una alegoría revolucionaria revisada
Authors: Pérez Ramírez Tatiana
Published: September 2020

Durante el periodo revolucionario, en la Sierra Juárez de Oaxaca hubo un levantamiento armado de mayo a noviembre de 1912. En los años ochenta del siglo XX, la historiografía oaxaqueña denominó a este acontecimiento “la revuelta ixtepejana”. En años recientes, gracias a la revisión de los archivos judiciales, se encontraron testimonios y los planes políticos de los dirigentes de esta revuelta. Con estos hallazgos, se elaboró un análisis de los discursos políticos de los líderes con sus demandas y la forma en que se adaptaron al contexto político. A partir de esto, es posible advertir las diferencias internas entre los participantes en este movimiento y sus intereses particulares. Con ello, se cuestiona si es posible mantener la denominación dada desde hace más de tres décadas. Quizá bajo la máscara de esta revuelta se oculta un fenómeno menos revolucionario y tal vez más complejo.
