Let X and Y be a pair of smooth manifolds, each obtainable
from the other by surgery in codimension at least three. We show that the
corresponding spaces Riem⁺(X) and Riem⁺(Y), respectively consisting of
Riemannian metrics of positive scalar...

Disease control of soilborne pathogens by biological control agents
(BCAs) is often inconsistent under field conditions. This inconsistency
may be partly influenced by pathogen diversity if there is a differential
response among pathogen species...

In recent years nuclear reduction of pyrimidines by catalytic
hydrogenation in acid media has been considered a possible synthetic
method for the preparation of substituted tetrahydropyrimidines.
This technique has the advantage of simplicity over...

Phospholipids of Tenebrio molitor larvae were
separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were
identified by various analytical procedures.
Phosphatidyl choline was demonstrated to be...
