The modified dynamics as a vacuum effect
نویسنده
چکیده
To explain the appearance in MOND of a cosmological acceleration constant, a0, I suggest that MOND inertia–as embodied in the actions of free particles and fields–is due to effects of the vacuum. The same vacuum effects enter both MOND (through a0) and cosmology (e.g. through a cosmological constant Λ). For example, a constant-acceleration (a) observer in de Sitter universe sees Unruh radiation of temperature T ∝ [a + a0], with a0 ≡ (Λ/3), and I note that T (a)−T (0) depends on a in the same way that MOND inertia does.

Optimization of freezing point regulator and its penetration dynamics on large yellow croaker
Different kinds of freezing-point regulators were evaluated to expand the freezing point zone of large yellow croaker, and several treatment methods such as ordinary atmospheric pressure, vacuum environment and injection during the process of penetration were compared to reveal the relationship of diffusion velocities, diffusion time and freezing point of the large yellow croaker. Results obtai...

This study was carried out to investigate the effects of three different packing methods including modified atmosphere, vacuum and common packaging on chemical, microbial and sensorial quality and shelf life of hot smoked Rainbow trout (Oncorhynchus mykiss) during storage at refrigerated temperature. For hot smoking, rainbow trout were gutted and cut in butterfly form and washed. Fish gutted br...
متن کاملTwo novel methods for synthesizing poly (propylene fumarate): Technical aspects and role of vacuum and N2 purging effects
Poly (propylene fumarate) (PPF), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. Many different methods have been reported for synthesizing PPF, but none of them gives a clear method. The present paper introduces two new methods in PPF synthesis: Modified reflu...
