Spenser Ter ry (1840-1914) was a nine teen th-cen tury Methodis t Episcopal ian. He wa s a g radu ate of Y ale Div inity Sch ool a nd p rofes sor o f Hebrew a nd O ld Testament exegesis and theology at Garrett Biblical Institute. He w as the author of Biblical Apocalyptics and numerous commentaries on Old Testament books, but is most often remem bered for his book Bib lical Hermeneutics, which ...
In brane-world theory in five dimensions, the bulk metric is usually written in gaussian coordinates, where g 4µ = 0 and g 44 = −1. However, the choice g 44 = −1 is an external condition, not a requirement of the field equations. In this paper we study the consequences of having g 44 = ǫΦ 2 , where ǫ = ±1 and Φ is a scalar function varying with time, ˙ Φ = 0. This varying field entails the poss...
Using a combination of HCHO planar laser-induced fluorescence and laser Doppler velocimetry measurements, the extinction behavior of methanol counterflow diffusion flames was examined experimentally under conditions in which the extinction was brought about by a vortex generated on the oxidizer side. Comparisons were made with quasi-steady extinction results for the same flames. It was found th...
For any ring homomorphism R −→ R′ of noetherian rings, the “extension of scalars” morphism from (Sch/R) to (Sch/R′) which sends X/R to X ⊗R R′/R′, extends to a group homomorphism from K0(Sch/R) to K0(Sch/R). Suppose A is an abelian group, and ρ is an “additive function” from (Sch/R) to A, i.e., a rule which assigns to each X ∈ (Sch/R) an element ρ(X) ∈ A, such that ρ(X) depends only on the isom...
Injections of extracts of the hypophysis cerebri have been tested by Szymonowicz and by Oliver and Sch~ifer during the course of their well-known experiments upon the effects of extracts of the adrenal glands. Szymonowicz * states that in two experiments of this kind, made upon dogs, he obtained a slight fall of blood pressure and a quickening of the heart beat, just the reverse of the cardiac ...
The syntheses of 1-N-(S-4-amino-2-hydroxybutyryl)-gentamicin B and 1-N-(S-3-amino-2-hydroxypropionyl)-gentamicin B, designated sch 20287 and Sch 21420, respectively, by procedures similar to those developed by KAWAGUCHI and co-workers for the transformation of kanamycin A to amikacin are described. The in vitro microbiological properties of Sch 20287 and Sch 21420 are compared with amikacin, ge...
We summarise the approach to brane cosmology known as " mirage cosmology " and use it to determine the Friedmann equation on a 3-brane embedded in different bulk spacetimes all with one or more extra dimensions. Usually, when there is more than one extra dimension the junction conditions, central to the usual brane world scenarios, are difficult to apply. This problem does not arise in mirage c...
Let X be a projective scheme over a noetherian base scheme S, and let F be a coherent sheaf on X. For any coherent sheaf E on X, consider the set-valued contravariant functor Hom(E,F) on S-schemes, defined by Hom(E,F)(T ) = Hom(ET ,FT ) where ET and FT are the pull-backs of E and F to XT = X ×S T . A basic result of Grothendieck ([EGA] III 7.7.8, 7.7.9) says that if F is flat over S then Hom(E,...
Infantile hemangiomas are endothelial tumors that grow rapidly in the first year of life and regress slowly during early childhood. Although hemangiomas are well-known vascular lesions, little is known about the mechanisms that cause the excessive endothelial cell proliferation in these most common tumors of infancy. To investigate the molecular basis of hemangioma, we isolated endothelial cell...
