The Identity of Odynerus Scudderi Cameron and O? Bradleyi Cameron (Hymenoptera: Vespidae: Eumeninae)

Biologic aspects of different species of Pachodynerus (Hymenoptera; Vespidae; Eumeninae).

The aim of this study was to compare biological aspects of the Pachodynerus species occurring in the Parque Municipal das Araucárias, Guarapuava, Paraná, Southern Brazil. It was carried from December 2001 to December 2004. Forty one nests belonging to 5 species were collected, of which 17 Pachodynerus guadulpensis, 15 Pachodynerus sp., 1 Pachodynerus argentinus, 1 Pachodynerus ca guadulpensis a...

The Cameron-Martin theorem

The Cameron–Erdős Conjecture

A subset A of the integers is said to be sum-free if there do not exist elements x, y, z ∈ A with x+y = z. It is shown that the number of sum-free subsets of {1, . . . , N} is O(2N/2), confirming a well-known conjecture of Cameron and Erdős.

Physics: Millikan and Cameron

layer is not altered by a five-hundred fold change in the surrounding pressure. Further evidence for believing that a condition characteristic of the metal itself has been reached is furnished by the fact that the photoelectric sensitivity of an outgassed specimen remains constant for twelve hours after heat treatment. The work of Davisson and Germer9 on electron reflection from nickel is also ...
