in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode Meloidogyne javanica on tomato in greenhouse conditions. P. lilacinus, effectively promoted the growth of plants inoculated with M. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

A general method for compressing the modulation time-bandwidth product of analog signals is introduced. As one of its applications, this physics-based signal grooming, performed in the analog domain, allows a conventional digitizer to sample and digitize the analog signal with variable resolution. The net result is that frequency components that were beyond the digitizer bandwidth can now be ca...

INTRODUCTION Trichosporon species are basidiomycetous yeastlike anamorphic organisms that are widely distributed in nature and found predominantly in tropical and temperate areas. In humans, this fungal species is occasionally part of the commensal flora of skin and mucosa, and can be responsible for superficial skin and hair infections (white piedra) or, more rarely, invasive infections in imm...

In this paper we discuss an oblique incidence and observation electronic speckle-pattern interferometer, in which we use an anamorphic prism in front of the object. A collimated beam traveling through the prism is partly reflected at the base of the prism. The reflected light is the reference beam and the transmitted light illuminates the diffuse object, thereby generating the object beam. In t...

The Wigner distribution of rotationally symmetric partially coherent light is considered, and the constraints for its moments are derived. Although all odd-order moments vanish, these constraints lead to a drastic reduction in the number of parameters that we need to describe all even-order moments: whereas in general we have (N + 1)(N + 2)(N + 3)/6 different moments of order N, this number red...

A mycoparasite, Scytalidium parasiticum sp. nov., isolated from the basidiomata of Ganoderma boninense causing basal stem rot of oil palm in Johor, Malaysia, is described and illustrated. It is distinct from other Scytalidium species in having smaller asci and ascospores (teleomorphic stage), longer arthroconidia (anamorphic stage), hyaline to yellowish chlamydospores, and producing a fluoresce...
