Recently, the optimization of power flows in portable hybrid power-supply systems (HPSSs) has become an important issue with the advent of a variety of mobile systems and hybrid energy technologies.In this paper, a control strategy is considered for dynamically managing power flows in portable HPSSs employing batteries and supercapacitors.Our dynam
Casearia sylvestris Sw.(Salicaceae) is noted for its morphological and chemical plasticity and pharmacological properties.The present study investigates two of its varieties: C.sylvestris var.sylvestris, predominant in dense and humid forests and ecotones and characterized by clerodane diterpenes; and C.sylvestris var.lingua, mainly found in xeric
Perovskite solar cells (PSCs) are third-generation photovoltaic technology that has gained a lot of attention due to its technological and economic advantages.The PSCs are characterized with low cost, high absorption, long copyright diffusion length, and low fabrication temperature.To model the performance of PSCs, a new dynamic model is proposed t
Background: Foreign body ingestion is a common presenting problem in our society.Rigid esophagoscopy for extraction of ingested foreign bodies is the recommended treatment.The purpose of this study was to present our experience with rigid esophagoscopy in removal of esophageal foreign bodies.Material & Methods: This descriptive study was carried ou
This publication is the first one in a series of brief lectures dedicated to the characteristics of the immunobiological control navy drapery fabric system, aetiology and pathogenesis, which most frequently occur in the medical practices of the immunepathological syndromes: immunodeficiencies, grandpas best allergic reactions, pathologic tolerance,
