‎In this paper we take $mathcal A$ to be the category {bf Pos-S}‎ ‎of $S$-posets‎, ‎for a posemigroup $S$‎, ${mathcal M}_{pd}$ to‎ ‎be the class of partially ordered sequantially-dense‎ ‎monomorphisms and study the categorical properties‎, ‎such as‎ ‎limits and colimits‎, ‎of this class‎. ‎These properties are usually‎ ‎needed to study the homological notions‎, ‎such as injectivity‎, ‎of‎ ‎$S$-...

foliar late blight resistance in other populations (Collins et al., 1999; Sandbrink et al., 2000). Association between A diploid Solanum population was developed with the objective QTL conferring foliar late blight resistance, tuberizaof mapping quantitative trait loci (QTL) associated with resistance tion, and vine maturity was found in four out of five to Phytophthora infestans (Mont.) de Bar...

BACKGROUND Countries worldwide recommend women planning pregnancy to use daily 400 microg of synthetic folic acid in the periconceptional period to prevent birth defects in children. The underlying mechanisms of this preventive effect are not clear, however, epigenetic modulation of growth processes by folic acid is hypothesized. Here, we investigated whether periconceptional maternal folic aci...
