The formulation of coffee blends is paramount importance for the industry, as it provides product with an expressive ability to compete in market and adds sensory attributes that complement consumption experience. Through redundancy analysis canonical correspondence analysis, possible study relationships between a set notes different proportions variety through multivariate linear regression mo...

The objective of this research was to study the relationships between environmental factors and distribution of Astragalus verus and Astragalus glaucops in order to find the most effective factors in the distribution of Astragalus verus and Astragalus glaucops in west of Iran. Sampling of soil and Floristic composition were performed with Eco-phytosociology method. Floristic composition data in...

Generalizing an example from (Fine 1975) and inspired by a theorem in (Jónsson 1994), we prove that any modal formula of the form π(p ∨ q) ↔ π(p) ∨ π(q) (with π(p) a positive formula) is canonical. We also prove that any such formula is strongly sound and complete with respect to an elementary class of frames, definable by a first order formula which can be read off from π.

Changes in species assemblages of intertidal foraminifera can be used to estimate the amount of earthquake-related subsidence during plate-boundary earthquakes at the Cascadia subduction zone. The accuracy and precision of foraminiferal methods in paleoenvironmental reconstruction is underpinned by the relations between contemporary taxa and their environment, which are used to calibrate fossil...
