The volume expansion rate and the age of the Universe [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1995
Under four assumptions such that 1) Einstein's theory of gravity is correct, 2) existence of foliation by geodesic slicing, 3) the trace of the extrinsic curvature, $K$, is negative at the present time in observed region, that is, the observed universe is now expanding, 4) the strong energy condition is satisfied, we show that $H_{v0} t_{0} \leq 1 ...

Volume expansion of a Swiss-cheese universe [PDF]

open access: yesPhysical Review D, 2002
In order to investigate the effect of inhomogeneities on the volume expansion of the universe, we study modified Swiss-Cheese universe model. Since this model is an exact solution of Einstein equations, we can get an insight into non-linear dynamics of inhomogeneous universe from it.

Volume expansion and flow promotion in shock [PDF]

open access: yesPostgraduate Medical Journal, 1969
Summary Volume replacement is the most important step in treating hypovolaemic shock. Blood is needed when the oxygen carrying capacity threatens to fall below a critical level, but has the disadvantage of transmitting virus hepatitis. Anicteric hepatitis is about four times more frequent than the icteric form. Pasteurized

Exit Pupil Expansion Based on Polarization Volume Grating

open access: yesCrystals, 2021
In this paper, we demonstrate a waveguide display structure which can realize a large field of view on a two-dimensional plane and a larger exit pupil size at the same time.

Induction of Adipogenesis by External Volume Expansion

open access: yesPlastic & Reconstructive Surgery, 2016
External volume expansion by suction is used to prepare the recipient site for fat grafting by increasing its compliance and vascularity. The authors previously developed a mouse model for external volume expansion and demonstrated its pro-proliferative and angiogenic effects. Increased thickness of the subcutaneous tissue was also observed. This study
