Isolation and chemical analyses of the cell walls of the yeast (Y form) and mycelial forms (M form) of Paracoccidioides brasiliensis and Blastomyces dermatitidis revealed that their chemical composition is similar and depends on the form. Lipids, chitin, glucans, and proteins are the main constituents of the cell walls of both forms of these fungi. There is(More)
In this paper a method for generating Oriented Bounding Boxes (OBB) using genetic algorithms (GA) is proposed. OBBs are used in a hierarchy of bounding volumes to detect collisions between objects. Currently, the most used method for generating OBBs is based on the covariance matrix (CV) of the points of the model, but it has many flaws and in most cases(More)
Warping techniques can be complicated and difficult to use, but through the use of fluid dynamics the warping becomes simple and it is intuitively controlled by physical properties such as viscosity and forces. These properties are naturally associated with the image itself or with spatial control handles. The key idea is to think of the image domain as a(More)
Space assets are continuously bathed by charged particles making their components susceptible to the effects of spacecraft charging. While their orbits are not embedded within the radiation belts, low earth orbiting assets with high inclinations do pass through the horns of these belts during each polar crossing, transiting through potentially dangerous(More)
A comparative study of the mycelial phase of Paracoccidioides brasiliensis and Blastomyces dermatitidis reveals that both fungi are very much alike, containing multiple nuclei and nuclear pores, mitochondria, ribosomes, scarce endoplasmic reticulum, intracytoplasmic membrane systems, glycogen, and vacuoles. Shadowed cell walls show fine fibrillar surfaces(More)
A 28-year-old patient went to the emergency room when he found it impossible to remove a metal ring he had placed on his penis 16 hours earlier. (This case was reported as a clinical note 3 years ago by our group1). The steel ring was 0.4-cm thick, had an inner diameter of 2 cm, and was located in the middle third of the penis (Figure 1-A) He did not wish(More)
The Space Environment Sensor Suite (SESS) is the set of instruments of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that takes measurements to produce space-environment data products. The SESS includes a complement of instruments that provide <i>in</i> <i>situ</i> data on particles, fields, aurora, and the ionosphere. The(More)
PURPOSE We report our results using lyophilized human dura mater for urethral strictures. MATERIALS AND METHODS The results of 131 urethroplasties using lyophilized human dura mater grafts were reviewed. The etiology of the stricture was unknown in most cases and 44.3% had not been previously treated. Mean stricture length was 10 cm. A dura mater patch(More)
