Trametes hirsuta and a purified laccase from this organism were able to degrade triarylmethane, indigoid, azo, and anthraquinonic dyes. Initial decolorization velocities depended on the substituents on the phenolic rings of the dyes. Immobilization of the T. hirsuta laccase on alumina enhanced the thermal stabilities of the enzyme and its tolerance against(More)
We report the case of a 6-year-old female patient with Ataxia Telangiectasia, an extremely rare condition, who developed in addition a left cerebellar astrocytoma and a right cerebellar infarction, considered as two independent events. Children with AT have an increased risk of developing cancer, but only few cases of glioma are reported and, at our(More)
This work presents a simpler method to obtain fingerprint classification by mean of directional map smoothing developed in C++ programming language through statistical techniques. That strategy allows to extract attributes of an image to increase the quality because it is possible to reduce the noise if compared with the result obtained by mean other method(More)
This work presents results on axonal arborization identification in cell culture of neurons from Helix aspersa with the use of the directional image method. We implemented the algorithm initially proposed for fingerprint recognition and classification, and adapted this idea to axonal classification and measure.
