A new green protocol for the synthesis of 2-substituted perimidines from hydrazones under catalyst- and solvent-free conditions
(Bulgarian Academy of Sciences, 2018)A new green protocol was developed for the synthesis of 2-substituted perimidines. The protocol involves a reaction of ethoxy carbonylhydrazone with 1,8-diaminonaphthalene under solvent- and catalyst-free conditions. Simple ... -
A new water-soluble zinc azaphthalocyanine containing azo groups: synthesis, characterization, fastness and antibacterial properties on cotton fabric
(E.U. Printing and Publishing House, 2023)A novel water-soluble zinc azaphthalocyanine containing azo groups (Azo-ZnAzaPc) was synthesized and characterized using FT-IR, H-1 NMR, C-13 NMR, UV-vis, MS and elemental analysis. A dyeing experiment was performed on ... -
A novel grey wolf optimizer based load frequency controller for renewable energy sources integrated thermal power systems
(Taylor & Francis Ltd., 2022)The frequency value should be kept constant to ensure and maintain synchronization in power systems. When the balance between generation and load is interrupted, the frequency value increases or decreases. This frequency ... -
A novel grid-net design to eliminate bycatch in beam trawl fishing for the veined rapa whelk in the south-eastern Black Sea
(Natl Centre Marine Research, 2018)Beam trawl fisheries in the Black Sea target the veined rapa whelk (Rapana venosa) while other species of fish and crabs are returned to the sea dead or alive. Smaller bivalves and crabs are also packed with the catch ... -
Nutrient fluxes from rainbow trout (Oncorhynchus Mykiss) feces and uneaten feed in the black sea conditions
(Parlar Scientific Publications (P S P), 2017)The phosphorus release from trout feces and feed at the low water temperatures (8 degrees C) occurred slowly, while at high water temperatures (20 degrees C) on the second day reached maximum levels (4.45 and 4.12 mg L-1 ... -
Occurrence of microplastics in herpetological museum collection: Grass snake (Natrix natrix [Linnaeus, 1758]) and dice anake (Natrix tessellata [Laurenti, 1769]) as model organisms
(Springer, 2022)Microplastics are plastic fragments with a size less than 5 mm in length. In addition to a threat to the marine environments where these are abundantly present, these have also started polluting freshwater ecosystems. ... -
