And also for university chemistry students (pre- and post-graduated), another interesting controversy could be the qualitative and quantitative chemical approaches (Chamizo 2018) between Pearson (1963) who proposed empirically his hard and soft acid-base model and Drago (1973). 7 Implicit Approach ...

Fluorine compounds are among the compounds that were found. The presence of fluorine compounds in coffee is also confirmed by the results of the studies that were conducted by by Wolska et al. [27]. Fluorine is naturally present in soil and water. Hence, its compounds may be present in cof...
Music is a complex phenomenon with multiple brain areas and neural connections being implicated. Centuries ago, music was discovered as an efficient modality for psychological status enrichment and even for the treatment of multiple pathologies. Modern research investigations give a new avenue for music...
