A probabilistic analysis of the biometrics menagerie existence: case study in fingerprint data

Until recently the use of biometrics was restricted to high-security environments and criminal identification applications, for economic and technological reasons. However, in recent years, biometric authentication has become part of daily lives of people. The large scale use of biometrics has shown that users within the system may have different degrees of accuracy. Some people may have trouble authenticating, while others may be particularly vulnerable to imitation. Recent studies have investigated and identified these types of users, giving them the names of animals: Sheep, Goats, Lambs, Wolves, Doves, Chameleons, Worms and Phantoms. The aim of this study is to evaluate the existence of these users types in a database of fingerprints and propose a new way of investigating them, based on the performance of verification between subjects samples. Once introduced some basic concepts in biometrics and fingerprint, we present the biometric menagerie and how to evaluate them.

Una excursión al zoológico : los comentarios y las fotografías de los niños.

Estudio con el objetivo de conocer el significado que los niños otorgan a una excursión. Los niños de entre 3 y 12 años dispusieron de una cámara fotográfica para poder enseñárselas al resto de sus compañeros. Las fotografías y comentarios fueron analizados por profesionales. Se incluyen fotografías, los comentarios y las entrevistas que se les realizaron a alumnos y padres.

Coneguem els animals al Parc Zoològic. 'Conozcamos los animales en el Parque Zoológico'.

Cuaderno educativo destinado al profesorado del ciclo medio de Educación Primaria. Su finalidad es acercar al alumnado al animal y poder descubrir sus morfologías y singularismos con facilidad. En concreto este cuaderno trata el tema de las aves, los mamíferos y las características generales de los vertebrados. Más a más, recogen en él una serie de sugerencias para el trabajo en clase. Por último, hay un apartado de bibliografía, apartado que se divide en: bibliografía para los alumnos y bibliografía para el maestro.

Estudo biológico e biométrico dos estádios ninfais de Rhodnius prolixus Stäl, 1859 (Hemiptera, Reduviidae) sob condições laboratoriais

Eggs and nymphs originated from couples of Rhodnius prolixus obtained from nymphs of the 5th instar were used for biological cycle and biometric studies. The following biological cycle parameters were determined under a temperature of 28°C and relative humidity, varying between 52 - 94% : medium period of incubation: 13.01 days; rate of eggs eclosion: 77.6%; medium period of development of the 1st, 2nd, 3rd, 4 th, 5th instar nymphs : 19.33, 19.09, 20.38, 24.37, 38.14 days, respectively; percentual of deaths in the nymph instar: 26.70, 14.00, 18.26, 17.02, 35.47% respectively; percentual of changes per instar nymphs; 73.30, 86.03, 81.73, 82.97, 64.52%, respectively. Biometric measurements performed, showed that in all the instars the abdomen is the largest segment. In the four first instars, the head is larger than the thorax. In the fifth instar, the head and thorax present are about the same size.

Anticorpos anti-Leptospira spp. em animais selvagens do zoológico municipal de Ribeirão Preto, Estado de São Paulo, Brasil

Leptospirosis may affect all domestic and wild animals as well as human beings. Some serological studies have shown the involvement of wild species in the epidemiology of the disease. Once captive wild animals are not much studied, especially in Brazil, the present study aimed to detect anti- Leptospira spp. antibodies in animals from Ribeirão Preto city zoo, in São Paulo state, Brazil. Blood samples were collected from captive birds, fish, reptiles and mammals, sinanthropics and free-living animals and also from employees between March and October, 2006. Four hundred and three blood samples were obtained, 388 animals' samples (110 reptiles, 143 birds, 110 mammals and 25 fish) and 15 humans'. The sera were analysed by Microscopic Agglutination Test using 22 serovars from pathological leptospiras and two from non-pathological serovars. Among the animal samples, 339 were from captive animals, and 49 from free-living ones, captured with traps inside the zoo. One hundred and three (103/388 = 26.5%) samples reacted to leptospirosis, ninety-two (92/339 = 27.1%) samples were from captive animals and eleven (11/49 = 22.4%) from free-living ones. All humans' samples were negative. Serological titles varied from 40 to 5.120, with predominance of titles between 40 and 80 and the most frequent serovars were Patoc, Andamana, Canicola, Icterohaemorrhagiae and Panama.
