A geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. The Kovin lignite is characterized by high moisture content, ...medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). The most abundant minerals in all lignite samples from the three coal seams are clays (illite/smectite), silicates (quartz, plagioclase), sulphates (gypsum/anhydrite) and carbonate (calcite). The other iron-rich minerals are sulphides, oxides and hydroxides (pyrite, magnetite, haematite, and limonite). In general, mineral matter in the matrix coal consists of illite/ smectite and quartz, while xylite-rich coals, apart from illite/smectite, have a higher content of sulphates and Fe-oxide/hydroxide minerals. The lignite from the Kovin deposit is enriched in As, Cd, Co, Cr, Cu, Ga, Li, Mn, Mo, Ni, Pb, V, Zn, Gd, Tb, Er and Lu in comparison with the Clarke values for brown coals. The statistical analysis of bulk compositional data shows inorganic affinity for the majority of the major and trace elements and possible association with pyrite, illite/ smectite and calcite.
Purpose: The purpose of this study was to examine the bibliographic corpus pertaining to the investigation of the impact of remittances on economic growth. Bibliometric analysis was utilized to ...evaluate the current state of the art and the dynamics of research papers published on the subject matter. Conversely, the Systematic Literature Review (SLR) method sought to scrutinize selected research papers to ascertain whether remittances play a contributory role in economic growth and whether this impact is contingent upon country level developments. Design: This study employed a mixed-methods approach, combining bibliometric analysis and SLR to address literature review questions which were formulated using the PICO framework. The study utilized the Web of Science database (WoS). Bibliometric analysis was conducted using VOS Viewer and Biblioshiny. The second part of the study involved SLR, following the PRISMA-2020 protocol, to further refine the selection of papers. Findings: The findings suggest that a large proportion of published papers do not come from countries with a high share of remittances in GDP, and the number of published research papers is not dependent on the income level of the country. The results indicate that there is a positive relationship between remittances and economic growth, and that this nexus varies depending on a country’s income level. More developed countries tend to utilize remittances more efficiently in their economies. Originality: To the best of the authors’ knowledge, the present study represents a novel investigation of the literature pertaining to the topic, utilizing the WoS database as a primary source. Moreover, the authors have advanced the methodological approach by employing a synthesis of both bibliometric analysis and SLR.
