Research of foam concrete quality by two-stage foam injection method in comparison with classical foam concrete

Technobius
The article presents a method of production of foam concrete, which involves two-stage injection of foam. The proposed method involves improving the pore structure of foam concrete, due to a more uniform distribution of pores throughout the volume of the material.

Effects of feeding almond hulls to light lambs on carcass characteristics and meat quality

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Almond hulls (AH) are the main by‐product of almond processing for human consumption and contain bioactive compounds that can improve meat quality. Although AH are used as feed for dairy cows in some countries, information on their potential effects on meat quality is limited.

Regularization and finiteness of the Lorentzian LQG vertices

, 2009
We give an explicit form for the Lorentzian vertices recently introduced for possibly defining the dynamics of loop quantum gravity. As a result of so doing, a natural regularization of the vertices is suggested.
