We examined the effects of supplemental food sources on parasitism of turf-infesting white grubs (Coleoptera: Scarabaeidae) by tiphiid wasps (Hymenoptera: Tiphiidae). Survival of spring active Tiphia vernalis Rohwer and late summer active Tiphia pygidialis Allen, parasitoids of Japanese beetle, Popillia japonicaNewman, andmasked chafer,Cyclocephala spp., grubs, respectively, was signiÞcantly in...

warning that deadly new strains of tuberculosis, virtually untreatable using the drugs currently available, appear to be spreading across the globe, raising the spectre of a resurgence in a disease which for many generations has laid in the background, seemingly beaten, but which may now make a major comeback as a lethal new pathogen. The new strains are known as extreme drug-resistant TB or XD...

Thermal blooming has been evaluated numerically in two-dimensional for CO2 laser beam transmitting through high pressure CO2 gas. Thermal blooming occurs when a portion of the laser beam is absorbed when transmitted through an absorbing medium such as atmosphere. High pressure gas medium is very useful for experimental simulations. In our calculation the beam was assumed to have an initially ri...

Life history theory links human physical and sexual development to longevity. However, there have been no studies on the association of intellectual development with longevity. This observational study investigates the relationship between the onset of intellectual maturity and lifespan through the life histories of composers and creative writers, whose intellectual development can be gauged th...

The objective of this research is to build an automatic method for recognizing a Thai blooming flower based on minimum distance for finding similarities between each type of Thai blooming flower. The Euclidean distance technique was applied in order to improve performance of retrieval processes. The flower images were acquired from digital cameras which were taken at close range to ignore the b...
