the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

This article describes an accurate subPico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both MEMS/NEMS and cryogenic technology applications. The MEMS/NEMS are described as either two Gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of e...

As an alternative to the construction of new infrastructure, repurposing existing natural gas pipelines for hydrogen transportation has been identified as a low-cost strategy substituting with in wake energy transition. In line that, 342 km, 36″ pipeline was used this study simulate some technical implications delivering same amount different blends and hydrogen, 100% hydrogen. Preliminary find...

To investigate the static characteristics of aerostatic journal bearings with porous bushing, flow model—in which compressibility lubricating gas is considered—is established based on Reynolds lubrication equation, Darcy equation for material, and continuity equation. With finite difference method, schemes non-uniform grids, relaxation virtual node numerical method governing equations compressi...

Currents in the compressible and incompressible regions of the two-dimensional electron gas We derive a general expression for the low-temperature current distribution in a two-dimensional electron gas, subjected to a perpendicular magnetic field and in a confining potential that varies slowly on the scale of the magnetic length ℓ. The analysis is based on a self-consistent one-electron descrip...

The leakage process simulation of a Natural Gas Liquid (NGL) storage tank requires the simultaneous solution of the NGL’s pressure, temperature and phase state in the tank and across the leak hole. The methods available in the literature rarely consider the liquid/vapor phase transition of the NGL during such a process. This paper provides a comprehensive pressure-temperature-phase state method...

The accuracy of the relationship between formation pressure and water saturation has a direct impact on predicting production performance coal reservoirs. As result, researchers are becoming more interested in this connection. most commonly used method to evaluate connection is semianalytic method, but it disregards matrix shrinkage pore compressibility, resulting inaccurate estimations for A m...
