‎We prove that a remainder $Y$ of a non-locally compact‎ ‎rectifiable space $X$ is locally a $p$-space if and only if‎ ‎either $X$ is a Lindel"{o}f $p$-space or $X$ is $sigma$-compact‎, ‎which improves two results by Arhangel'skii‎. ‎We also show that if a non-locally compact‎ ‎rectifiable space $X$ that is locally paracompact has a remainder $Y$ which has locally a $G_{delta}$-diagonal‎, ‎then...

this study was conducted to study the effect of organic acids on the preservation of alfalfa nutritional value after harvesting. a split plot design with 4 treatments and 3 times was conducted in which organic acids were sprayed on the 30percent moisture content forage before baling. treatments were: 1) forage without additives as control, 2) pure propionic acid, 1percent, 3) acetic acid percen...
