The neurotropic black yeast Exophiala dermatitidis has a possible origin in the tropical rain forest
The black yeast Exophiala dermatitidis is known as a rare etiologic agent of neurotropic infections in humans, occurring particularly in East and Southeast Asia. In search of its natural habitat, a large sampling was undertaken in temperate as well as in tropical climates. Sampling sites were selected on the basis of the origins of previously isolated strains, and on the basis of physiological ...
متن کاملBlack rain: The burial of the Galilean satellites in irregular satellite debris
0019-1035/$ see front matter 2013 Elsevier Inc. A http://dx.doi.org/10.1016/j.icarus.2013.01.008 ⇑ Corresponding author. E-mail address: [email protected] (W.F. Bo Irregular satellites are dormant comet-like bodies that reside on distant prograde and retrograde orbits around the giant planets. They are likely to be captured objects. Dynamical modeling work indicates they may have been cau...
متن کاملTropical Rain Classification and Estimation of Rain from Z-r (reflectivity-rain Rate) Relationships
A Z-R relation is derived using a data set which consists of nine rain events selected from Singapore’s drop size distribution. Rain events are separated into convective and stratiform types of rain using two methods: the Gamache-Houze method, a simple threshold technique, and the Atlas-Ulbrich method. In the Atlas-Ulbrich method, the variability of the rain integral parameters R, Z, Nw, D0 and...
متن کاملAcid Rain
Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...
متن کاملRain structure transfer using an exemplar rain image for synthetic rain image generation
This letter proposes a simple method of transferring rain structures of a given exemplar image (rain image) into a target image (non‐rain image). Given the exemplar rain image and its corresponding masked rain image, rain patches including real‐life rain structures are extracted randomly, and then residual rain patches are obtained by subtracting those rain patches from their mean patches. Next...
