GROWTH OF SCIENTIFIC PUBLICATIONS: AN ANALYSIS OF TOP TEN COUNTRIES

The aim of this study is to examine the growth of scientific publications of top ten most productive countries during the period 1996 – 2015. The data was obtained from the SCOPUS database. Compound Annual Growth Rate and Relative Growth Index have been employed. The study reveals the growth pattern of top ten countries during the period 1996-2015 and shows the research concentrations in major disciplines. China registered highest growth during the period 1996-2015 and only India registered higher growth from 1996-2005 to 2006-2015. Further, there is a contrast in the pattern of growth rate of top ten countries in major disciplines

Scientific Productivity of Leading Countries

The main aim of this study is to analyze and compare the scientific productivity of major countries. The related data are collected from Scopus through the open-access portal www.scimagojr.com. Data has been collected on the number of documents and their rank for the top countries. Bibliometric indicators such as Compound Annual Growth Rate (CAGR) and Activity Index (AI) have been used along with a simple percentage. Further, Pearson correlation has been used to compare the rankings. Twenty-four countries have at least 1% of global scientific output in 2018, and all these top countries also ranked in Nature Index 2019 except Indonesia and Malaysia. The top two countries, the United States and China, produced more than 600,000 documents in 2018, with others following distantly. The majority of the top countries are grouped under upper-middle and high income. Fifty percent of the top countries are from Europe. Tremendous improvement in terms of global rank from 1998 to 2018 has been observed for Iran, Indonesia, and Malaysia. All the top countries focus on different disciplines.https://dorl.net/dor/20.1001.1.20088302.2022.20.2.8.

Modeling the Growth of Telemedicine Literature

The study elaborates the current publication trends in the field of telemedicine as well as the application of growth models to forecast future trends with the goal of determining the fitness of growth in publications using exponential, linear, and logistic growth models. The data for the study was downloaded from the Scopus database over a fifteen-year period, from 2005 to 2019. During the period, a total of 45719 publications were found with publication productivity showing an upward trend throughout the period. The results show that the growth of publications fits into the exponential model than linear or logistic models. This study also predicts that by 2025 there will a total of 108268 publications in the field of Telemedicine, as well as progressive research

Wie wirken "effektive Mikroorganismen" auf EM-Bokashi in der Bananenproduktion (Musa ssp.)?

In Costa Rica, ‘effective microorganisms’ (EM) are used to produce organic fertiliser in the form of Bokashi. This study aimed at investigating the effects of EM addition on the decomposition of banana residues during Bokashi production in comparison to different non-EM control variants (Bokashi produced with: W= water, M= molasses as an EM additive, EMst= sterilized EM). Furthermore, the effects of the above mentioned Bokashi variants on the growth of young banana plants and their effects on the secondary root growth of adult banana plants were evaluated. In comparison to non-EM controls, no increasing effects of EM on the N-mineralization of banana material were observed. All nutrient concentrations were similar for all treatments as well as the weight loss of approximately 77.9 %. The ergosterol concentration was significantly highest in EM Bokashi (77 µg g-1 dry soil), whereas it was lowest in EMst (29 µg g-1 dry soil). Application of all Bokashi variants significantly increased shoot growth of young banana plants under greenhouse conditions compared to a control grown in unamended soil. EM Bokashi and Bokashi produced with molasses significantly decreased the number of root nematodes under greenhouse conditions if compared to the control (nematodes per 100 g: C = 254; W = 143; EMst = 143; M = 67; EM = 38). Furthermore, EM Bokashi increased secondary root growth of adult banana plants in the field (186.7 g) compared to non-composted fresh banana leaves (134.6 g) and a control without mulch application (147 g)
