Global polystyrene (PS) production has been influenced by the lightness and heat resistance this material offers in different applications, such as construction and packaging. However, population growth and the lack of PS recycling lead to a large waste generation, affecting the environment. Pyrolysis has been recognized as an effective recycling method, converting PS waste into valuable products in the chemical industry. The present work addresses a systematic, bibliometric, and statistical analysis of results carried out from 2015 to 2022, making an extensive critique of the most influential operation parameters in the thermo-catalytic pyrolysis of PS and its waste. The systematic study showed that the conversion of PS into a liquid with high aromatic content (84.75% of styrene) can be achieved by pyrolysis. Discussion of PS as fuel is described compared to commercial fuels. In addition, PS favors the production of liquid fuel when subjected to co-pyrolysis with biomass, improving its properties such as viscosity and energy content. A statistical analysis of the data compilation was also discussed, evaluating the influence of temperature, reactor design, and catalysts on product yield.

Faced with contemporary dynamic, it is important to assess the scenario and assumptions of the organizations in the budget process for the continuity of the entity. Several scientific studies have attempted to analyze this theme, however, they present a gap in the sample specifically involving the postgraduate studies in the stricto sensu. Thus, this article aimed to analyze the current bibliometric profile of Brazilian scientific production on the budget topic, using the CAPES Bank of Theses and Dissertations as a data source. This work is characterized as a descriptive research and uses the quantitative approach to measure, through bibliometric analysis, characteristics of academic production on the theme Budget in the stricto sensu courses from 2012 to 2018. This work contributes to the accounting literature by filling the existing gap and analyzing a sample that has been responsible for the growth of Brazilian scientific production. The analysis of the 48 productions sought to identify aspects methodological and content, in addition to the level of production by institution. The results show: the southeast region as the most prolific; predominance of the quantitative approach and thematic area aimed at public administration; majority use of survey and archive/documentary methods; predominant use of national literature as a reference; and topic approach on the interviewees’ perception of the budget process or evaluation of aspects related to management, such as budget efficiency and execution. There was also an increase in the average annual production in the period analyzed for periods previously studied.

When dealing with agrifood systems of beef cattle, conventional and differentiated systems coexist, involving a multiplicity of definitions. This article aims to conduct a survey of the production of knowledge on the theme “Coordination of Agrifood Systems” in the last seven years., in order to provide contributions to the contextualized understanding of production and to base the agenda for future research on theme. A bibliometric survey was performed followed by descriptive and analytical analysis. The results point to the predominance of studies focusing on conventional systems, however, presents opportunities for studies in differentiated systems. Beef and beef cattle are among the most researched objects, being the main approach to qualitative research through case studies. On the subject, international studies focus more on quantitative research when compared to Brazil, showing greater interest in this approach. The main theories used are the Transaction Cost, Measurement Cost and the Network Theory, as well as their respective authors. The main objectives are associated with the understanding of the various coordination mechanisms, involving trust, hybrid forms, innovation It was found that the coexistence of two agri-food, and the diversity of ways to study the theme, are indicative for studies that can contribute to the advancement of research on agri-food systems.

 

 

The general objective of this work is to evaluate characteristics of international scientific production in technologies associated with Industry 4.0. The methodology employed consists of two stages: (i) selection of technologies (terms) pointed out in the specific literature; (ii) the bibliometric analysis of scientific publications that contain the characteristic terms of Industry 4.0 existing in the Scopus database. The hypothesis adopted was that, as it is still an ongoing process, Industry 4.0 and its concepts are still under construction. Some of the conclusions of the work are: the countries that stand out the most are those that implemented national strategies related to the technologies of Industry 4.0, obtained, in the subsequent years, a wide growth in the number of publications; and, among the financing institutions, the governmental ones stand out in the sponsorship of scientific publications, especially the Chinese ones, proving the public effort.

 

 

Rockfall is one of the main phenomena in mountainous environments due to its fast and high speed of movement, its unpredictability, and, therefore, the difficulty of identifying signs of instability and detachment of the blocks. Compared to other types of sliding, the proportion of rockfall research is smaller and sometimes little known, but, in the last five years, rapid growth in this area has been shown. Therefore, this research aimed to review the intellectual structure of rockfall, through analysis of scientific production using bibliometric techniques that allow its analysis, knowledge, global evolution, and future trends in rockfall. The research methodology consists of three steps: (1) data compilation, (2) software and data cleaning, and (3) analysis, interpretation, and visualization.
