Legionellosis is mostly caused by Legionella pneumophila (Lp) and is defined by a severe respiratory illness with a case fatality rate ranging from 5 to 80%. In a previous study, we showed that a glycosaminoglycan (GAG)-binding adhesin of Lp, named Lcl, is produced during legionellosis and is unique to the L. pneumophila species. Importantly, a mutant depleted in Lcl (Δlpg2644) is impaired in a...

The resonant power conversion having many advantages over conventionally adopted pulse width modulation that includes a high efficiency, low electromagnetic interference, small volume, low switching losses, and light weight of components due to a high switching frequency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This paper presents the doubly loaded r...

The work presented in this paper deals with a proposal of new topology multilevel inverter to act as Static synchronous Compensator (STATCOM). proposed is the five-level Asymmetric Stacked Multi-Level Inverter (ASMLI). One essential features that distinguishes it from conventional types achieves required voltage levels fewer switching devices, leading simplifying control process. Moreover, incl...

The article presents an induction generator connected to the power grid using AC/DC/AC converter and LCL coupling filter. Three-level inverters were used in converter, both from side side. algorithm realizing Pulse Width Modulation (PWM) has been simplified maximum. Control of was based on Direct Field-Oriented (DFOC) method. At same time, voltage control for this solution. MPPT extended includ...
