A s tudy has been made of rabbits vaccinated with living tubercle bacilli of human type and subsequently exposed to tuberculosis under conditions simulating the natural modes of human contagion. In view of the present world-wide s tudy of the prophylact ic inoculation of human beings with BCG and other vaccines, the desirability of a method by which the safety and efficacy of a given procedure ...

Loblolly pine seedlings were grown in 1 x 5 inch biodegradable plastic tubes for 10, 12, and 14 weeks at densities of 42, 84, 126, and 168 per square foot. Seedling density and age significantly affected seedling development at time of outplant ing, and densi ty became more important as greenhouse growing t imes increased. Al l morphological characteristics measured when seedlings were planted-...

The WAVES investigation on the WIND spacecraft will provide comprehensive measurements of the radio and plasma wave phenomena which occur in Geospace. Analyses of these measurements, in coordination with the other onboard plasma, energetic particles, and field measurements will help us understand the kinetic processes that are important in the solar wind and in key boundary regions of the Geosp...

The evolution of a complex beam width parameter g describing focusing or defocusing of a paraxial Gaussian beam is considered as the cause of an additional topological (Berry) phase of the electromagnetic f ield associated with the beam. It is pointed out that the well-known Gouy phase is a special case of such a phase that should arise in general in all symplectic systems.  1995 Optical Socie...
