to breaking dormancy as well as the effect of light, temperature, salinity and drought stress on germination of cutleaf mignonette seeds, experiments were conducted at the research laboratory of birjand faculty of agriculture in 2009. immersion in sulfuric acid (96%) for 30 seconds under continuous dark regime resulted in the highest germinability (73%) and the lowest germination (8%). was obse...

The evolution of building codes typically produce design provisions that are expected to create safer and more accurate designs. We as engineers expect building codes to advance the state of the art with each successive edition. The 2009 International Building Code (IBC) and the Building Code Requirements for Structural Concrete (ACI 318-08) have significant revisions affecting the design of ti...

Recall that some of the substitution rules mentioned the function FV : {λ-terms} → Var: FV(x) = {x} FV(e1 e2) = FV(e1) ∪ FV(e2) FV(λx. e) = FV(e)− {x}. Why does this definition uniquely determine the function FV? There are two issues here: • Existence: whether FV is defined on all λ-terms; • Uniqueness: whether the definition is unique. Of relevance here is the fact that there are three clauses...

BACKGROUND Since at least the late 1990s, HIV has been viewed as a major threat to efforts by countries to reduce under-5 mortality. Previous work has documented increased under-5 mortality due to HIV from 1990 to 1999 in Africa. The current analysis presents estimates and trends in under-5 mortality due to HIV in low- and middle-income countries by region up to 2009. METHODS The analyses are...
