This study conducts a systematic comparative critical discourse analysis of news reports from prominent American (CNN) and Russian (RT) media sources covering the Russia-Ukraine conflict. Utilizing the theoretical frameworks of Norman Fairclough's multidimensional model and Teun van Dijk's socio-cognitive approach, the research examines the underlying ideological assumptions and discursive strategies employed by the two contrasting news channels. Quantitative analysis of discursive techniques and linguistic features provides insights into how each channel selectively utilizes language to convey distinct ideological positions. The findings demonstrate how media discourse constructs and normalizes particular ideological representations of political conflicts. Detailed linguistic analysis reveals that RT reports largely reflect pro-Russian ideological stances, legitimizing Russian actions through authorization of official sources, while portraying the West as an antagonist through metaphorical framing. Conversely, CNN coverage predominantly espouses pro-Western ideological views supporting Ukraine, manifested in more frequent delegitimization of alternative perspectives, nominalization to obscure agency of Western actors, and use of synonyms framing conservative criticism negatively. Thus, despite applying similar overarching discursive methods, each channel subtly employs rhetorical, grammatical and lexical strategies to convey ideologicallyoriented representations aligned with particular geopolitical interests. This research contributes to understanding how media discourse can implicitly embed certain worldviews and underlying belief systems through strategic linguistic andPage 22 of 32 rhetorical devices. Critical discourse analysis of media texts is crucial for identifying hidden mechanisms of persuasion and manipulation within news narratives
Mass transfer has been studied at rotating cylinder electrodes fabricated with spiral-wound woven-wire meshes using reduction of copper as a test reaction. The experimental data were correlated by an empirical expression between the Sherwood number and the Reynolds number, both regarding the hydraulic diameter as a characteristic length. It was found that the Sherwood number was dependent upon the Reynolds number to the power of 0.521. An enhancement factor was adopted to compare the efficiency of the new rotating cylinder electrode with previous three-dimensional rotating cylinder electrodes. The results showed that the new type has a mass-transfer enhancement factor 2.3 times higher than those obtained with smooth rotating cylinder electr

Show MoreThis systematic review aimed to investigate the relation between orthodontic treatment (OT) and the incidence of the gingival black triangle (GBT) after completing treatment with a fixed orthodontic appliance, as well as the associated risk factors and the level of alveolar bone. Electronic and hand searches were conducted in three electronic databases for relevant articles published up to March 2022. Retrieved articles went through a two-step screening procedure, and the risk of bias (RoB) was assessed by the Joanna Briggs Institute checklists. The incidence of GBT after OT was set as the primary outcome, while the secondary outcomes were the risk factors associated with GBT and alveolar bone loss following OT. Out of 421 papers, 5
