Adsorption is a powerful method for wastewater treatment. The adsorbent materials used are limited due to the high cost of production and for their difficult regenerability. This work aims to show the importance of reusing agricultural residues, transforming them into efficient adsorbent materials. Highlighting the growing interest in the subject through bibliometric analysis and punctuating the main preparation techniques with direction for specific characteristics desired in the materials, understood through the main techniques of physical and chemical characterization. It will also be shown the economic and quantitative relevance for Brazil of some agricultural crops of worldwide occurrence, as well as the potential of transforming their residues into adsorbent materials for the treatment of effluents. Finally, studies involving real effluents will be presented, corroborating the efficiency of these materials and the possibility of future industrial applications. This set of information presents the reader with a valuable amount of information about the real possibility of reusing agricultural solid waste as a powerful tool in the treatment of urban and industrial effluents, thus increasing reuse and attacking two important environmental problems.

 

 

In recent years, efforts have been expanded to create and adopt tools that contribute to mitigating the environmental impact caused by industrial development. In this sense, the objective of this article is twofold: (i) to identify the countries worldwide that have generated and disseminated the most information on sustainable supply chains (SSCs) and (ii) to recognize the organizations that have interacted most with each other to generate greater scientific contributions on SSCs. Methodologically, the starting point was a bibliometric scan, and a systematic review of the literature focusing on SSCs was carried out. The search engine used was the Dimensions platform, limited only to the years 2020, 2021 and 2022, and the articles had to belong to the categories of engineering and economics. For the network visualization, VOSviewer was used, as it allows the connections to be visualized in a network graph. The findings of this paper show the existing links between organizations worldwide whose purpose is the study and scientific dissemination of SSCs. The countries that have generated the greatest scientific contribution in the last three years with respect to SSCs were China, the United Kingdom, the United States, Italy and the Netherlands. In addition, the organizations that have interacted the most belong to the European Union.

 

 

Ensuring access to published research is increasingly important for demonstrating research impact, supporting wide readership, creating interest in collaboration, and making way for funding opportunities. This article provides a bibliometric analysis of publications from 20072016 in the Web of Science (WOS) database to update understanding of recent international library science research as a means of discussing research impact and scientific collaboration. The methodology is a descriptive analysis of publications retrieved from the WOS database using keywords “library science” and WOS-generated subject descriptor “Information Science & Library Science.” Analysis focused on descriptive data related to our research questions including representation of countries, languages, and journals. The findings reveal that most publications are published by researchers with institutional affiliations in the United States and in English. Library and information science research continues to be strong in collaboration, but international and interdisciplinary collaborations are still low in this sample. The dataset reflects that co- and multi-authored publications have the highest WOS citation counts, reinforcing the value of scholarly collaboration. This research provides a baseline to chart future growth in Library Science research publications and collaborations.

 

 

The potential of paraprobiotics and postbiotics to be used as beneficial agents for human health has caused an effort by the scientific community to gather information about the bioactivity of these compounds and production methods. Understanding the evolution of scientific research in this area of study is important to understand the future perspectives and the main bottlenecks of scientific and technological development involving these compounds. In this scenario, this review work used a bibliometric analysis tool intending to improve the scientific documentation, bringing information and communicating the results to the scientific community through the quantitative analysis of the current literature, available in one of the main databases, the Web of Science, also providing recent information on the evolution and future perspectives in the field of paraprobiotic and postbiotic development. The results of this study showed that the main studies discuss the bioactivity of these compounds. Concerning the development of functional foods, there is a need for extensive research on production methods and the interaction of these compounds with food. However, it concluded that much still needs to be studied to prove the claims of bioactivity, especially when used for the development of functional foods.

 

 

Introduction: the goal of this research was to identify and understand the social network connections co-authored by the faculty of the Masters in Documentation and Information Sciences of the Languages Department of the School of Arts and Humanities of the University of Lisbon. We aimed to discuss the concepts and methods of analysis that ground this study: social network, co-authorship, social network analysis and bibliometric analysis. Method: this is an exploratory study supported by qualitative and quantitative approaches. For data collection, it uses the Ciencia Vitae platform, and for modeling and analyzing the social network, it uses the software Gephi. Results: the data collected in Ciencia Vitae and the social network connections and data generated in Gephi software were analyzed and discussed, thus validating the social network connections and identifying two eminent clusters and one isolated link. Conclusions: it achieves the proposed objectives and the investigation validates the existence of the information network between the professors of the course and external researchers, making it possible to understand the informational flow and verify that there are professors who do not have ties of connection by co-authorship with each other.

 

 

Purpose – This paper aims to study the FinTech enterprises and the management theories related to this subject in a scientific way. Design/methodology/approach – This study is a bibliometric study on FinTech enterprises. Its origin is a survey of 1,749 papers in 6 traditional peer-reviewed academic databases (e.g. Science Direct and Scopus) and in the “gray” literature, published by other agents and not subject to double-blind peer review. In this analysis we use three approaches: academic paper or not; journal main interest, and main purpose of the paper. Findings – The first approach shows 45% of papers without blind review. The second approach shows no concentration on any journal. It represents no concentration on any kind of specific journal. And the third approach shows four kinds of contents in all researched papers: FinTech categorizations; FinTech related to theory of disruptive innovation; FinTech and theories of administration or economy; and finally, FinTech and regulatory and legislative aspects. Originality/value – The findings identified the emergence of new research strands, precedence of studies of “gray” literature to explain the phenomenon, distribution of studies in different fields of knowledge (e.g. information technology, business and law) and lack of consensus in theories to explain the matter.

 

 

Context: Because of the recent pandemic COVID-19, research on management systems health information grew rapidly, underscoring the importance of knowing the investigative trends in these issues to identify the findings and global networks knowledge. Aims: To examine the developments and research trends in information management in health. Methods: A bibliometric analysis was carried out with the 215 results obtained from a search equation performed in the Scopus database. Documents were selected using the inclusion criteria according to the recommendations of the international declaration PRISMA and calculation was performed indicators of quality, quantity, and trend analysis. Results: These were identified as trends: Managing information and knowledge, Educational model/Curriculum design, information-seeking behavior. A research agenda also arises with the themes: reconfiguration of health policies, design and collaborative use in digital resources, telemedicine, meta-analysis tools for decision-making and cloud infrastructures.

Coastal lagoons provide several ecological resources and services with their functioning being mainly investigated in temperate areas. The Patos Lagoon, a subtropical system in southern Brazil, is one of the largest chocked coastal lagoons in the world. It provides habitat for numerous organisms and a range of ecosystem services. We performed a bibliometric analysis to identify and analyze the characteristics of studies carried out in the Patos Lagoon based on articles published in peer-reviewed journals indexed in the Science Citation Index Expanded database of Clarivate Analytics Web of Science and Scopus database. We found 360 articles published between 1965 and 2019 in 150 journals. The number of articles has increased in the last decades mainly resulting from national collaborative efforts. Most articles were published by Brazilian research institutions. Most studies were performed in the Patos Lagoon estuary, a Longterm Ecological Research program ‘ s study site. Our study thus highlights the importance of long-term projects to the comprehension of subtropical coastal lagoons functioning and indicates knowledge gaps that must be addressed in future studies.

 

 

Introduction: descriptive study on Brazilian scientific output in agricultural sciences based on the scientific articles indexed in Scopus between 2008-2017. Method: it uses bibliometric indicators of production, and the software BibExcel and Excel to visualize area characteristics. The corpus is composed of 109,084 papers indexed by Scopus. Results: the research found that the growth of scientific output in agricultural sciences is not constant in the Brazilian states and, when examining the profile of publication by Brazilian federative units, it founds that the investigated states presented a preference for publication in national journals. This observation reiterates previous studies and, thus, it says that it is a tendency of publication in the agricultural sciences. Some states, such as Minas Gerais, Rio de Janeiro, Rio Grande do Sul, Parana, Sao Paulo and Ceara show a certain regionality in the dissemination profile of their scientific output since they prefer local journals to disseminate the results of their researches. Another prominent factor in the publication profile is the preferred language being English, even in national journals. Conclusions: The results of the study demonstrate the heterogeneity of the distribution of Brazilian scientific production in agricultural sciences, highlighting each Brazilian state.

 

 

The skies of Northern Chile are considered among the best in the world for astronomy due to their geographical, climatic and atmospheric conditions. In fact, during the last several decades, a great number of astronomical observatories have been built by space research institutions devoted to space research, turning Chile into one of the countries with the greatest astronomical observation capacity in the world. Consequently, it is relevant to explore and assess the development of astronomy in Chile during the last ten years (2005-2015), carrying out a bibliometric analysis to extract traditional metrics, complemented with alternative metrics, to identify the Chilean production and scientific contribution of research in this field of knowledge. The results from traditional metrics, based on the information obtained in the Web of Science (WoS) database analyzed through InCites for the Astronomy & Astrophysics category indicate a sustained increase of the scientific production for the discipline during the last ten years. In particular, the Normalized Citation Impact of organizations and institutions conducting research in Chile is above the worldwide average. On the other hand, the alternative metrics, including for instance, the altmetrics types presented by the SCOPUS database, reflect that the Chilean research impact is much lower in the context of social networks.
