There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

in this research, a semi empirical approach has been suggested for calculating the activation energyof unimolecular thermal decomposition of vinyl ethers yielding saturated products. the calculationprocedure is based on the use of molecular mechanics (mm) methods. these methods which involvethe construction of the transition state for a molecule mainly consider the formation of a “hydrogenbridg...

several empirical methods for flood flow rate estimation have been presented. in this study,eight new empirical runoff estimation method including dredge & burge, bourges, inglis, faning, hyderabad, burkli ziegler, cramar and possenti were calculated in bakhtegan watershed which is located in fars province. after studying empirical methods for annual flood flow rate estimation and comparing...

the edinburgh school of social epistemology is one of the emergent contemporary schools of epistemology which has been systematically put forth and formulated since the late 1960s. theorizing, the edinburgh school specifically deals scientific knowledge (natural sciences) and is chiefly characterized by the fact that it criticizes root and branch the scientific knowledge sociologically. that is...

Abstract We empirically evaluate 20 prominent contributions across a broad range of areas in the empirical corporate finance literature. assemble necessary data and apply single, simple econometric method, connected-groups approach Abowd et al. to appraise extent which prevailing specifications explain variation dependent variable, differ composition fit arising from various classes independent...

Background Medicalization has been a topic of discussion and research for over four decades. It is a known concept to researchers from a broad range of disciplines. Medicalization appears to be a concept that speaks to all, suggesting a shared understanding of what it constitutes. However, conceptually, the definition of medicalizat...

One of the important, practical and simple methods for hydrate formation conditionis empirical equations, and so far many empirical equations have been presented to predict thetemperature and pressure of hydrate formation. In this study, the methods and empiricalcorrelations have been reviewed and their predictive capabilities have been evaluated with ...
