Phytate and phosphorus utilization by broiler chickens and laying hens fed maize-based diets

Qiugang MA, Markus RODEHUTSCORD, Moritz NOVOTNY, Lan LI, Luqing YANG

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 4, Pages 380-387 doi: 10.15302/J-FASE-2019276

Abstract: Broiler chickens and laying hens have the potential to degrade phytate in the gastrointestinal tract,Published values of phytate degradation in broilers are overall higher than those in laying hens.

Impacts of different diameter combinations on the temperature of a crude oil pipeline when colocating with a products pipeline

Bo YU, Yue SHI, Xin LIU, Jinjun ZHANG, Jinjia WEI,

Frontiers in Energy 2010, Volume 4, Issue 2, Pages 192-197 doi: 10.1007/s11708-009-0074-1

Abstract: In order to show the effects of different diameter combinations on crude oil temperature when a crude oil pipeline and a products pipeline are laid in one trench, four typical diameter combinations are selected to conduct numerical simulation. After a series of calculations, the minimum mean temperature difference and the maximum temperature difference of the crude oil along the pipelines are obtained. In real pipeline constructions, the effects of other diameter combinations on crude oil temperature can be predicted by the method of linear interpolation to calculate results of the four diameter combinations obtained in this study.
