Foliicolous fungi from Arctostaphylos pungens in Mexico

Arctostaphylos pungens "Manzanita" is an important shrub in the southwestern USA, and northern and central Mexico. Manzanita bears apple-like fruit that is utilised for a range of edible products. Over the past two years, several foliar disease problems were noted on this host in the San José de Gracia region of Mexico. The aim of the present study was to elucidate their identity through the an...

Foliicolous microfungi occurring on Encephalartos

Species of Encephalartos, commonly known as bread trees, bread palms or cycads are native to Africa; the genus encompasses more than 60 species and represents an important component of the indigenous African flora. Recently, a leaf blight disease was noted on several E. altensteinii plants growing at the foot of Table Mountain in the Kirstenbosch Botanical Gardens of South Africa. Preliminary i...

IAU XXIX General Assembly

Body Solar system bodies are observed at many scattering angles. The reflection and polarization change withphase angle of light scattered from particulates has been studied for a century in the lab in efforts tounderstand clouds, aerosols, planetary ring systems and planetary regoliths. These effects must beunderstood in order to infer surface properties from astronomical data. The...

Xxix . Detection and Estimation Theory

a. In Quarterly Progress Report No. 84 (pages 225-226) we described a state-variable formulation for the estimation and detection problem when the signal is a sample function from a nonstationary process that has passed through a dispersive medium. Work has continued in this area and we are attempting to find effective solution procedures for the equations that result. The state of current prog...
