Atmospheric Forces

Gravitational Tidal Forces and Atmospheric Processes

Recent studies have revealed a relationship between variations in gravitational tidal forces and rainfall. A possible mode of interaction of the tidal forces on atmospheric processes is suggested to explain how the tidal forces which are small may induce detectable effects on atmospheric circulation, considering both synoptioscale and shortperiod processes in the atmosphere. The variability of ...

The Effect of High Heel Shoes on Tibiofemoral and Patellofemoral joint Contact Forces and Muscle Forces

Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking.   Materials & Methods: A tot...

Internal Forces in Piles “Under External Forces and Earthquake in Homogeneous and Nonhomogeneous Media”

SOME POINTS ON CASIMIR FORCES

Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...
