soil crusting has long been recog- nized as an obstacle to seedling emergence.This is particularly Costumes true with small-sized seed.Soil crusts will often result after a soil is wetted by rain or sprinkling and then dried.Seeds planted during the winter or spring months in much of California stand a very good chance of Ileinp rained on, allowing
Language attitude in foreign language pedagogy becomes an interesting discussion, especially in Office English language teaching learning process.Teachers and learners are the importance of teaching learning process, including the language attitude in the pedagogical process.Due to the importance of the language attitude, this paper sheds to descri
Is a group best off if everyone co-operates? Theory often Costumes considers this to be so (e.g.the "conspiracy of doves"), this understanding underpinning social and economic policy.We observe, however, that after competition between "cheat" and "co-operator" strains of yeast, population fitness is maximized under co-existence.To address whether t
Oxygen reduction reaction (ORR) remains challenging due to its complexity and slow kinetics.In particular, Pt-based catalysts which possess outstanding ORR activity are limited in application with high cost and ease of poisoning.In recent years, nitrogen-doped graphene has been widely studied as a potential ORR catalyst for replacing Pt.However, th
Epoxidized palm oil (EPO) is environmentally friendly, biodegradable, T-Shirts and a relatively less costly processing aid.In this study, we investigated the suitability of EPO in place of aromatic processing oils in styrene butadiene rubber.The curing properties, mechanical properties, abrasion resistance, and heat buildup properties of rubber com
