![]() In contrast, in clinical scenarios when the history and/or physical exam findings consist of vague and difficult-to-interpret elements, the resulting discordance may challenge some clinicians' sense of mastery. The Pandora spectrometer system is designed to look at the Sun (tracking to within 0.1 ), or to look at the sky at any zenith or azimuth angle, to gather information about the amount of trace gases or aerosols that are present.Ĭlinicians, regardless of discipline, tend to prefer those areas of their practice in which they feel a sense of mastery, a confidence in their ability to manage the conditions being presented to them by their patients. The Pandora systems are built from off-the-shelf commercial parts and from mechanical parts machined using electronic machine shop drawings. An additional software component reduces the raw data (spectrometer counts) to preliminary scientific products for quick-view purposes. The data are automatically stored on a miniature computer (netbook) for automatic download to a designated server at user defined intervals (once per day, once per week, etc.), or to a USB external device. All functions are available through a GUI so as to be easily accessible by the user. The software also controls the attached spectrometer exposure time and thermoelectric cooler to maintain the spectrometer temperature to within 1 C. Pandora Operation and Analysis Software controls the Pandora Sun- and sky-pointing optical head and built-in filter wheels (neutral density, UV bandpass, polarization filters, and opaque). Herman, Jay Cede, Alexander Abuhassan, Nader A hypothesis is thus proposed that some sort of biochemical signals may exist in the host-pathogen interaction so that the fungal pathogen perceives the signals for prompt response to forthcoming host-density changes by either producing conidia for infecting available hosts or forming resting spores for surviving host absence in situ. nouryi upon the concentration of infective inoculum. This clarified for the first time the dependence of in vivo resting spore formation of P. ![]() The P(CFRS)-C relationship fit well the logistic equation P(CFRS) = 0.6774/ (r(2) = 0.975). Surprisingly, the proportion of mycosed cadavers forming resting spores (P(CFRS)) increased sharply within the concentrations (C) of 28-240 conidia mm(-2), retained high levels at 240-1760, but was zero or extremely low at 0.3-16. Host nymphs showered with primary conidia of an isolate (LC(50): 0.9-6.7 conidia mm(-2) 4-7 days post shower) from air captures in the low-latitude plateau of China produced resting spores (azygospores), primary conidia or both spore types. To explore the possible mechanism involved in the process, Pandora nouryi (obligate aphid pathogen) interacted with green peach aphid Myzus persicae on cabbage leaves under favourable conditions. Resting spore formation of some aphid-pathogenic Entomophthorales is important for the seasonal pattern of their prevalence and survival but this process is poorly understood. Resting spore formation of aphid-pathogenic fungus Pandora nouryi depends on the concentration of infective inoculum.
