Knowledge mapping analysis of safety ergonomics: a bibliometric study

Although a significant attention, the field of safety ergonomics has not yet been systematically profiled based on recent studies. To fully understand the current research status, basis, hotspots, and development trends in the field, 533 documents from the Web of Science core database were used for knowledge mapping analysis by the bibliometric method. The study found that the USA is the top country in publications, and Tehran University is the institution with the highest number of publications. Ergonomics and Applied Economics are the authoritative safety ergonomics journals. Through co-occurrence and co-citation analysis, current safety ergonomics research is focussed on healthcare, product design, and occupational health and safety. The keyword timeline view indicates that the main research paths are occupational health and safety, and patient safety research. The analysis of burst keywords shows that safety ergonomics research in management, model design, and system design areas are research frontiers in the field. Practitioner summary: This paper presents a knowledge mapping of safety ergonomics research through bibliometric analysis. The research results show the research status, research hotspots, and research frontiers in the field of safety ergonomics, which provides a direction for other scholars to quickly understand the development of this field.</p

Mapping the Knowledge Domain of Corrosion Inhibition Studies of Ionic Liquids

Ionic liquids have received much attention in metal corrosion inhibition due to their unique properties of nontoxicity, low contamination, and high efficiency in corrosion inhibition. To fully understand the current status and latest progress of research in corrosion inhibition, we analyzed the literature using a systematic bibliometric method and visualization technology. The relevant studies specifically included co-occurrence analysis, cluster analysis, cocitation analysis, and keyword burst detection analysis. The results show that Asian countries, led by China, constitute the central research force in this ionic liquid corrosion inhibition field. Materials science, applied physics, and applied chemistry were the core disciplines in this research field, and the Journal of Molecular Liquids, Corrosion Science, Electrochim Acta, and Industrial & Engineering Chemistry Research were the core journals. The hot research topics in this field had been roughly divided into five timelines, representing five research topics: ionic liquid, solution, corrosion resistance, corrosion inhibitor, and film. The ionic liquid corrosion inhibition field has many research directions and a wide range of frontier branches. Among them, electrochemistry, molecular simulation, and electrolyte solutions have become the frontier of ionic liquid corrosion inhibition research

A major QTL conferring resistance to Verticillium wilt detected on chromosome 6.

<p>Linkage group c6 (a) was constructed from LHB22×JM11 F_2:3 population and linkage group c6 (b) was constructed from LHB22×NNG F_2:3 population. The c6 (c) map was drawn according to a consensus map of cotton <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096226#pone.0096226-Guo1" target="_blank">[31]</a> and only the related markers were selected. The QTL <i>qVW-c6-1</i> was detected in LHB22×JM11 population in 2010 at seedling stage in greenhouse (E1), and was further detected at flowering stage in 2011 (E2) and mature stage in 2011 (E3) and 2012 (E4) in LHB2×NNG F_2:3 population.</p
