In this paper, we discuss the self-consistency condition for the spherical symmetric Klein-Gordon equation. And then discuss a natural possibility that gravity and weak coupling constant gG and GW may be defined after gEM . In this point of view, gravity and the weak force is subsidiary derived from electricity. Unified solution for each particle field is calculated. ∗Electronic address:nisikaw...

BACKGROUND Endothelial cells (EC) guard vascular functions by forming a dynamic barrier throughout the vascular system that sensitively adapts to 'classical' biomechanical forces, such as fluid shear stress and hydrostatic pressure. Alterations in gravitational forces might similarly affect EC integrity, but remain insufficiently studied. METHODS In an unique approach, we utilized Electric Ce...

Gravity is a key factor for life on Earth. It is the only environmental factor that has remained constant throughout evolution, and plants use it to modulate important physiological activities; gravity removal or alteration produces substantial changes in essential functions. For root gravitropism, gravity is sensed in specialised cells, which are capable of detecting magnitudes of the g vector...

The equivalence principle suggests to consider gravity as an infra-red phenomenon, whose effects are visible only outside Einstein’s free-falling elevator. By curving spacetime, General Relativity leaves the smallest systems free of classical gravitational effects. However, according to the standard semi-classical treatment, indirect effects of gravity can be experienced inside the elevator thr...

Special features of surface gravity waves in deep fluid flow with constant vertical shear of velocity is studied. It is found that the mean flow velocity shear leads to non-trivial modification of surface gravity wave modes dispersive characteristics. Moreover, the shear induces generation of surface gravity waves by internal vortex mode perturbations. The performed analytical and numerical stu...

A number of studies have demonstrated that sex differentially affects responses to stress and pain. In this study, sex-related differences in pain responding were investigated in a gravity-induced analgesia model, where the effects of stressful high-gravity loading (1.5G or 2.0G for 10 min) on nociceptive behavior in male and female rats were investigated. In each rat, eight sites (nose, both f...

Local Lorentz transformations play an important role in teleparallel gravity theories, which a tetrad is conventionally employed as fundamental field variable describing the gravitational field. It commonly understood that modifications of general relativity framework break certain notion local invariance, present pure formulation such while another covariant preserved. We illuminate these diff...
