ON THE CHOICE OF CONTACT PARAMETERS FOR THE FORCED RESPONSE CALCULATION OF A BLADED DISK WITH UNDER PLATFORM DAMPERS

On the choice of contact parameters for the forced response calculation of a bladed disk with under platform dampers

Underplatform dampers (UPDs) are still in use to reduce the vibration amplitude of turbine blades and to shift the position of resonant frequencies.The dynamics of blades with UPDs is nonlinear and the analysis is challenging from both the experimental and the numerical Accessories point of view.A key point in obtaining a predictive numerical tool

Potential distribution of the primary malaria vector Anopheles gambiae Giles [Diptera: Culicidae] in Southwest Nigeria under current and future climatic conditions

Abstract Background Mosquitoes are key vectors for the transmission of several diseases.Anopheles gambiae is known to transmit ACTIVE LIVER pathogens of malaria and filariasis.Due to several anthropogenic factors such as climate change and population growth leading to diverse land use, their distribution and disease spreading pattern may change.Thi

Cholesterol suppresses antimicrobial effect of statins

Objective(s):Isoprenoid biosynthesis is a key metabolic pathway to produce a wide variety of biomolecules such as cholesterol and carotenoids, which target cell membranes.On the other hand, it has been reported that statins known as inhibitors of isoprenoid biosynthesis and cholesterol lowering agents, may have a direct antimicrobial effect on the

Machine-learning-based investigation of the variables affecting summertime lightning occurrence over the Southern Great Plains

Lightning is affected by many factors, many of which are not routinely measured, well understood, or accounted for in physical models.Several commonly used machine learning (ML) models have been applied to analyze the relationship between Atmospheric Radiation Measurement (ARM) data and lightning data from the Earth Networks Total Lightning Network

Radial artery pseudoaneurysms treated by ultrasound-guided differential compression: An effective and simple method

Transradial approach has become preferable to conventional femoral artery access for both diagnostic coronary angiography and percutaneous coronary intervention.A rare but recognizable complication of radial access is 159 radial artery pseudoaneurysm (RAp), which represents a potentially catastrophic complication.Treatment options comprise ultrasou
