As a preliminary experiment to measuring milksolids (fat plus protein) production of dairy cattle grazing swards containing different levels of white clover (Trifolium repens L.) nine Jersey and nine Friesian cattle housed indoors during late lactation and fed diets containing either 20, 50 or 80% white clover with the balance perennial ryegrass (Lolium perenne L.). During the first 10 day meas...
We start this article by rebuilding higher operads of weak higher transformations, and correct those in cite{Cambat}. As in cite{Cambat} we propose an operadic approach for weak higher $n$-transformations, for each $ninmathbb{N}$, where such weak higher $n$-transformations are seen as algebras for specific contractible higher operads. The last chapter of this article asserts that, up to precise...
A key question for climate change adaptation is whether existing cropping systems can become less sensitive to climate variations. We use a field-level data set on maize and soybean yields in the central United States for 1995 through 2012 to examine changes in drought sensitivity. Although yields have increased in absolute value under all levels of stress for both crops, the sensitivity of mai...
