The paper shows that a large class of underactuated vehicles cannot be asymptotically stabilized by either continuous or discontinuous state feedback.Furthermore, stabilization of an underactuated stuart products emcelle tocopherol surface vessel is considered.Controllability properties of the surface vessels is presented, and a continuous periodic
In order to investigate the dynamic characteristics of blunt aircraft mounted with aerospikes and aerodisks in large-amplitude force-pitching, the Roe spatial scheme and the lower-upper symmetric Gauss-Seidel (LU-SGS) method with dual time step are employed for discretization of unsteady Navier-Stokes (N-S) equations.A parametric investigation on t
Chitosan (CH) nanofibrous structures containing sulfadiazine (SDZ) or sulfadiazine modified chitosan (SCH) in the form of functional nanoparticles attached to nanofibers (hybrid nanostructures) were obtained by mono-axial and coaxial electrospinning.The mono-axial design consisted of a SDZ/CH mixture solution fed through a single nozzle while the c
Given the emergence of the coronavirus disease 2019 (COVID-19), zoonoses have raised in the spotlight of the scientific community.Animals have a pivotal role not only for this infection, but also for many other recent emerging and re-emerging viral diseases, where they may represent both intermediate hosts and/or vectors for zoonoses diffusion.Toda
Summary: Skull osteoradionecrosis may happen after radiation therapy for head and neck cancer.Here in, the authors present a case of intracranial carcinoma with osteoradionecrosis and exposure of frontal stuart products emcelle tocopherol usc trojans snapback hat bone with a large communication between nasal cavity and anterior fossa associated.The
