The investigation of non-stationary wave phenomena in isotropic viscoelastic solids using analytical approaches is the aim of this paper.Concretely, the problem of a thin homogeneous disc subjected to radial pressure load nonzero on the part of its rim is solved.The external excitation is niner rkt 9 rdo 2023 described by the Heaviside function in
http://dx.doi.org/10.5028/jatm.v5i1.192 The present work addresses a sensitivity analysis investigation of the aeroelastic stability margins for the VSB-30 sounding rocket during the atmospheric flight phase.Parametric stability analyses are performed considering variations of the inertia properties of the modular payload.Such variations can be cau

Phaeohyphomycosis is a fungal infection caused by Dermatiacae group of fungi, by Cladosporium spp.The term phaeohyphomycosis was introduced by Ajello et al.in 1974 to designate infections by brown pigmented filamentous fungi.Cladosporium oxysporum is a very rare etiological angilina white agent in humans.Phaeohyphomycosis of the cervical lymph node
Roads affect wildlife in different ways.Road construction increases fragmentation of habitats, influences landscape pattern and alters the physical environment.Roads act as barriers to animal movements, increase their mortality rates and cause other primaluna evo 400 preamp negative impacts on biodiversity.The current paper overviews the assessment
