Using PSD (Power Spectral Density) data on electron density and electric field variations observed on board Aureol-3 satellite at low-to-mid-latitude ionosphere we analyze a scale distribution of ICE FREEZE HAIR SPRAY the ionospheric turbulence in a form k-α, where k is the wave number and α is the spectral index.At first, high-resoluti
Local resonance is a key reason for fatigue damage of gear housings.Local modals could be excited by vibration caused by gear meshing.Considering the shearer rocker arm for example,the local resonance characteristics SUNGLASSES of gear housing are analyzed in this paper.Finite element method is used to obtain the natural characteristics of housing
One of the most significant factors in the estimation of dimension stone quarry cost is the production rate of rock cutting machines.Evaluating the production rate of chain-saw machines is a very significant and practical issue.In this research, it has been attempted to evaluate and select the suitable working-face for a quarry by examining the max
Fatigue is a common symptom of numerous acute and chronic diseases, including myalgic encephalomyelitis/chronic fatigue syndrome, multiple sclerosis, heart failure, cancer, and many necklace others.In these multi-system diseases the physiological determinants of enhanced fatigue encompass a combination of metabolic, neurological, and myofibrillar a
