BACKGROUND Reproductive hens are subjected to a restricted diet to limit the decline in fertility associated with change in body mass. However, endocrine and tissue responses to diet restriction need to be documented. OBJECTIVE We evaluated the effect of different levels of feed restriction, with or without fish oil supplementation, on metabolic parameters and adipokine levels in plasma and m...
It has been shown experimentally by many researchers that cooling rate and crystallization temperature affect the rate of crystal formation. In this study, crystallization kinetics of coconut oil was measured by monitoring the solid fraction of the oil using pulsed Nuclear Magnetic Resonance (pNMR). Four levels of cooling rate and crytallization temperature were studied. Parameters of crystalli...
The challenge of a deep-water oil leak is that a significant quantity of oil remains in the water column and possibly changes properties. There is a need to quantify the oil settled within the water column and determine its physical properties to assist in the oil recovery. There are currently no methods to map acoustically submerged oil in the sea. In this paper, high-frequency acoustic method...
In terms of sharp drop of international oil prices in the second half of 2008 after heading skyward in the first half of 2008 following continual growth since 2005, while at the same time certain parity among energy prices was disrupted, the author of this article tried to investigate key factors that influenced oil and gas industry and to answer the question what would be a »fair» price of cru...
Borehole magnetic resonance (MR) is routinely used to estimate the viscosity of light oil, even when it is mixed with water in the pore space of reservoir rock. However light oil methods are inadequate when oil viscosity is above several thousand mPa-s. There have been a number of publications relating magnetic resonance measurements to heavy oil viscosity, but the correlations proposed have no...
Oil-water two-phase flow widely exists and its measurement is of significance in oil well logging, oil transportations and etc. One of the techniques in common use in oil-water two-phase flowrate measurement is the Differential Pressure (DP) meters combining a theoretic model connecting the mass flowrate of the mixture with the differential pressures generated by the throttling element inside t...
