The study of natural convection from a heat source located at the bottom of partially top vented enclosure is presented.Air cooling for electronic components situated at the bottom of a top vented enclosure Serving Platters is studied theoretically.The flow was assumed to be laminar, steady and of constant physical properties.The process was descri
Introduction and aim: Oils are usually obtained (by pressing or extraction) from such plant raw materials as rapeseed, sunflower, flax and soy.Currently, there is an increasing interest among consumers of new types of oil obtained from non-traditional plant raw materials.A lot of attention is paid to seeds and stones of fruit, which are also the ma
The sonatas for violin and accompaniment by José Herrando (Valencia, ca.1720–Madrid, 1763) have undergone various transformations since the 1920s, reflecting a process of continuous ‘re-creation’ that illustrates the latest notions of ‘musical work’.Changes in performance practice, especially the emergence of Historically Informed Perfom
BackgroundKnowledge of the quantity and quality of apps related to coronavirus disease (COVID-19) is lacking.In addition, no directory has been established listing all the apps developed to address the COVID-19 pandemic.ObjectiveThe aim of this study was to identify smartphone apps designed to address the COVID-19 pandemic and to analyze their char
This research paper proposes the use of empirical equations to estimate the temporal maximum scour that is induced by twin-propeller ( ε t w i n = Ω t [ l n ( t ) ] Γ t ) when acting over non-cohesive bed materials.A purpose built experimental apparatus is used to obtain the measurement data required for the calculation of the empiri
