Introduction: This study presents a global research scenario in the broad domain of osteoarthritis (OA) research, using quantitative and qualitative publication and citation indicators. Methods: The study is based on 45,368 global publications, sourced from the Scopus bibliographical database, covering three decades (1994–2023). We studied the performance of the top 12 developed and top 12 developing countries. The key countries, organizations and authors at national and international levels were identified. The broad subject areas and key journals contributing to global OA research were delineated, besides identifying the broad characteristics of highly cited papers in the field. Results: The United States and China were the most productive countries, while the Netherlands and Canada made the largest citation impact. Harvard Medical School and the University of Sydney made the most contribution, while Boston University and Pfizer Inc., USA registered the highest citation impact. Hunter DJ and Guermazi A were the most productive authors, while Lohmander LS, and Hochberg MC registered the highest citation impact. Osteoarthritis and Cartilage (n = 4879) and Annals of the Rheumatic Diseases (n = 786) published the maximum papers, while Arthritis and Rheumatism and Nature Reviews Rheumatology registered the largest citation impact. The highly cited papers with 100 or more citations constituted 6.25% of the total publications. Conclusions: There has been a systematic growth of publications on OA. The research on OA was mainly done in developed countries, with the maximum publications coming from the United States of America, China and Canada. The most impactful publications on OA were from the Netherlands, Canada and the United States of America. [ABSTRACT FROM AUTHOR]

Solid waste management refers to collecting, treating, and disposing of solid waste that has served its purpose or is no longer useful. The primary purpose of this research is to map and visualize the solid waste management literature indexed on the Web of science between 1966 and 2021 based on bibliometrics analysis. This study also identified the most productive authors, sources, organizations, countries, research areas, funding agencies etc. This study employed the bibliometric method to analyze global research productivity on solid waste management literature. A total of 4444 research papers downloaded from the Web of science during the study period. Bibliometrics software, namely Bibexcel, VOSviewer, Biblioshiny, and Microsoft Excel, used to analyze the data. The results show that there was 4444 publication with 78759 citations between 1966 and 2021. The maximum number of papers, i.e., 424 published in 2020, in 1966 single paper published and received one citation. The journal Waste management published 382 papers and became the most relevant source of the topic, whereas Huang GH recognized as the most prolific author with 214 papers. China contributed a significant number of research papers in the field, while the University of Regina, Canada, emerged as a top-performing institution. China and Canada together collaborated more in producing literature in solid waste management. The study concludes that there is a need for further bibliometric study of other related topics in waste management, such as liquid waste management and gasses waste management.

• There was an rapidly increase in plant critical dilution curve (PCDC) study in recent years. • PCDC has been applied to more than 30 species by the scientists from 40 countries. • INRA developed PCDC theory, institutions from China and Canada are emerging groups. • Crop modeling and remote sensing in PCDC studies significantly increased recently. The concept of plant critical dilution curve (PCDC) has been studied on several crop species for about four decades, which has been widely applied in studies of crop nutrition evaluation, growth predictions, and fertilization management. This bibliometric analysis comprehensively explores the evolution trends in PCDC research based on literature data retrieved from the Web of Science from 1985 to 2019. The dynamics of the basic characteristics such as outputs, citations, institutions, authors, keywords and research topics of the published papers were studied. The results showed that the outputs and citations remained very low in the early years, then increased gradually, and increased quickly in recent years. INRA from France developed the theory, while research institutions from China and Canada as emerging groups applied the theory in different crops for crop N, growth, and quality indices as well as integrated it with non-destructive tools such as chlorophyll meter and remote sensing technologies in recent years. The frequency of the keywords "nitrogen nutrition index", "use efficiency", "management", "leaf area index" and "vegetation index" in the PCDC study increased over years. The PCDCs along with a number of crops, such as wheat, maize, rice, forage grasses, potato, canola, and tomato, have been widely studied in different countries. Research on PCDC has mainly focused on the theory and development of PCDC, including P, K, S, and their interaction, crop modeling, remote sensing and non-destructive techniques, nutrition diagnosis and fertilization management. Analysis of the published papers revealed that crop modeling and remote sensing are emerging fields. The research trends proposed were: generic PCDCs for crop species, the interaction of N-P-K-S for balanced fertilization, and application of PCDC in crop modeling and remote sensing.
