Dietary fiber effects on passage rate and breath hydrogen

The American Journal of Clinical Nutrition, 1985
Fermentation of fiber and passage to the large intestine were monitored by measuring hydrogen gas (H2) concentration in expired breath. Five subjects consumed meals containing no added fiber or 40 g of wheat bran (WB), corn bran (CB), oat bran (OB), or citrus flour (CF) replacing white flour.

The rate of time's passage

Analysis, 2009
1. Many philosophers say that time has a kind of flow or passage that distinguishes it from space. Future times and events become less future; past ones become more past; persisting things grow older. The world is caught up in a process of purely chronological change. This is the dynamic view of time.

Ruminal passage rate as affected by CrNDF particle size

Animal Feed Science and Technology, 1992
Abstract Fractional rumen passage rates of three particle sizes of CrNDF (less than 0.3, 0.6–1.0 and 15–25 mm) and of CoEDTA were estimated in an experiment with three lactating and three non-lactating rumen-fistulated cows, fed grass silage ad libitum and 7 kg and 1 kg of concentrates, respectively.

Local condensation heat transfer rates in fine passages

International Journal of Heat and Mass Transfer, 2003
Abstract A novel apparatus capable of quantitative control of local heat flows to single fine passages through thermoelectric coolers has been developed. Local heat transfer coefficients for flow condensation of HCFC-123 and of R11 have been measured for a wide range of mass fluxes (70–600 kg m −2  s −1 ), heat fluxes (15–110 kW m −2 ), vapour ...

First passage times, correlation functions, and reaction rates

The Journal of Chemical Physics, 1997
The mean lifetime of a particle in the presence of an absorbing boundary is the mean first passage time to the boundary. For diffusive dynamics on a one dimensional potential, we establish an exact relation between the mean first passage time to x=a, averaged over a (pseudo) equilibrium distribution in the region a⩽x<∞, and the time integral of ...

Effects of Passage Length on Listeners' Rate Preference

Perceptual and Motor Skills, 1977
A traditional paired-comparison procedure was employed for determining 20 listeners' rate preferences for prose recordings. The results suggest that a one-sentence prose passage may be used in place of a longer length passage with an equivalent outcome for rate-preference research.

Universal equivalence of mean first-passage time and Kramers rate

Physical Review E, 1999
We prove that for an arbitrary time-homogeneous stochastic process, Kramers's flux-over-population rate is identical to the inverse of the associated mean first-passage time. In this way the mean first-passage time problem can be treated without making use of the adjoint equation in conjunction with cumbersome boundary conditions.

First-Passage Problem in Foreign Exchange Rate

2004
We analyze tick-data of yen-dollar exchange rate and study the distribution of first-passage time (in short FPT), which is defined by the time that the rate firstly moves out from a given range. We report that the distribution of FPT is well described by a stretched exponential function with.

The determinants of slave mortality rates on the middle passage

Explorations in Economic History, 1982
An economic model of the middle passage of the African-American slave trade is presented. The model is used to explain why previous researchers have obtained unsatisfactory results when analyzing the factors that contributed to slave mortality rates which were higher than those observed on other ocean voyages at the time.

Diagnosis of Urolithiasis and Rate of Spontaneous Passage During Pregnancy

Journal of Urology, 2011
Due to imaging limitations little is known about the true rate of spontaneous stone passage during pregnancy. We evaluated the accuracy of urolithiasis diagnosis during pregnancy and the rate of spontaneous passage.We retrospectively reviewed the records of patients diagnosed with urolithiasis during pregnancy from 1997 to 2009. Patients were evaluated
