Foods of the Australian Brush-tailed opossum, Trichosurus vulpecula, were identified from stomach contents of 360 opossums collected from May 1975 to May 1976 in Ashley State Forest, Canterbury, New Zealand. Plant species eaten were identified with the aid of reference cuticles prepared from known plant species collected from the study area. Thirty different foods were identified, but only seve...

Birds arrive sequentially at their breeding ground where the nest sites vary in value (measured by reproductive success). Each bird may choose a vacant site or challenge an occupier for its site. In the latter case, the occupier is presumed to be the more-likely winner; the loser incurs a cost and must go to a vacant site. In a previous paper (Broom et al., 1997, J. theor. Biol.189, 257-272), w...

Hypersensitivity pneumonitis (HP), is an inflammatory disease that represents one possible response of the interstitial and parenchymal tissue to the intensive and repeated inhalation of organic dusts or reactive chemicals substances. In this case report, for the first time in the literature as we know, acute hypersensitivity pneumonitis in a patient who working in broom grass manufacturing wer...

Phytoplasmas have the smallest genome among bacteria and lack many essential genes required for biosynthetic and metabolic functions, making them unculturable, phloem-limited plant pathogens. In this study, we observed that transgenic Arabidopsis (Arabidopsis thaliana) expressing the secreted Aster Yellows phytoplasma strain Witches' Broom protein11 shows an altered root architecture, similarly...

BACKGROUND The witches' broom disease is a plague caused by Moniliophthora perniciosa in the Theobroma cacao, which has been reducing the cocoa production since 1989. This issue motivated a genome project that has showing several new molecular targets, which can be developed inhibitors in order to control the plague. Among the molecular targets obtained, the UDP-N-acetylglucosamine pyrophosphor...

An infection of the fungus Moniliophthora perniciosa in cocoa trees reduces productivity plant. In this study, concentrations mineral nutrients healthy leaves and vegetative broom plant were determined, relationship between disease nutritional composition was assessed. The samples analyzed using wet digestion method determined by inductively coupled plasma optical emission spectrometry Kjeldahl...

One of the most important themes in agricultural science is the identification of virulence factors involved in plant disease. Here, we show that a single virulence factor, tengu-su inducer (TENGU), induces witches' broom and dwarfism and is a small secreted protein of the plant-pathogenic bacterium, phytoplasma. When tengu was expressed in Nicotiana benthamiana plants, these plants showed symp...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...

Coplanarity is a relationship of a set of points that exist on a single plane. Coplanarities can be easily observed in a scene with planer surfaces, and these types of coplanarities have been widely used for 3D reconstructions based on geometrical constraints. Other types of coplanarities that can be observed from images are those observed as cross sections of planes and scenes; for example, po...
