Sixteen surface (5) and groundwater (11) samples were collected from the south-eastern part of Attica, Greece, analysed for physico-chemical parameters microplastics (MPs) by optical microscopy Raman microspectroscopy (RS). A total 3399 particles optically identified in all sixteen samples, ranging only 16 particles/L a sample deeper borehole to 513 shallow water well. They then visually classified into eight categories based on their color, texture, size, reflectivity, shape, general...
Water and its management have played a pivotal role in the evolution of organisms civilizations, fulfilling essential roles personal use, industry, irrigation, drinking from ancient times to present. This study seeks evaluate groundwater quality for irrigation Northern Peloponnese region, specifically wells Loutraki Schinos areas springs Gerania Mountains (Mts.), using geo-environmental indices ionic ratios. For first time, been applied region where serves multiple purposes, addressing...
The main objective of the present study was to develop a real-time mineral classification system designed for multiple detection, which integrates classical computer vision techniques with advanced deep learning algorithms. employs three CNN architectures—VGG-16, Xception, and MobileNet V2—designed identify minerals within single frame output probabilities various types, including Pyrite, Aragonite, Quartz, Obsidian, Gypsum, Azurite, Hematite. Among these, V2 demonstrated exceptional...
Graphite inclusions in diamond, K-bearing clinopyroxene, garnet and kyanite graphite coatings around microdiamonds from the ultrahigh-pressure Kokchetav Massif, northern Kazakhstan were investigated by means of scanning electron microscopy, laser Raman spectroscopy X-ray diffraction. Important observations include increasing size crystals diamond–graphite interface to external part coatings, high volume fraction presence composite successively formed diamond core–graphite mantle zone–diamond...
Natural diamond from three ultrahigh-pressure metamorphic (UHPM) terranes (Erzgebirge Massif, Germany; Kokchetav Northern Kazakhstan; Rhodope Metamorphic Province, Greece) and synthetic cutting polishing materials (paste, spray, saw blade) were studied by means of optical microscopy Raman microspectroscopy, to constitute a new petrographic spectroscopic data set that might be useful tool for identifying characterizing diamond. Several criteria are established distinguishing natural...
Groundwater deterioration due to agricultural activity is mainly attributed intense fertilization, groundwater overpumping and seawater intrusion being more pronounced in coastal areas. Irrigation return water one of the main sources aquifers enrichment it expected become source simultaneous reduction amount/frequency precipitation for many areas Greece Mediterranean. The quantity enhanced concentrations fertilizer residues, such as nitrates, well documented. Moreover, heavy metals both...
