Abstract: the present study investigates the calliphorid fauna in the biological reserve of tinguá using faunistic indices. monthly samplings were carried out using traps containing sardines that were exposed for 48 hours at the sites: a, at the border of the forest; b, 1,000 m towards the interior of the forest; and c, 500 m towards the interior of the forest. the objective was to study the calliphoridae fauna in forest environments using faunal indices. during the course of the experiment, 26 calliphorid species were collected. the species singletons, doubletons, uniques, duplicates, intermediate and common were defined. richness and richness estimation (estimators chao 1 and 2, jackknife 1 and 2, ace, ice and bootstrap), diversity (shannon-wiener index), evenness (pielou's index), and similarity of the sites (using the sorensen coefficient and the southwood percent similarity) were calculated. sites a and b had the same number of species of calliphoridae (23), representing a greater richness than site c (16). the sites differed only in their rare, intermediate and common species composition. the greatest number of intermediate species was found at a. at b, the numbers of rare, intermediate and common species were similar. at c, there were fewer rare species than intermediate and common ones. jackknife 2 at site b produced a higher value, however, indicating that it was possible to collect five other species in the reserve and three more species at a and c. diversity was greatest at b, but evenness was similar at the sites. b and c showed a greater level of similarity in species composition (dendogram); l. nigripes and mesembrinella bellardiana, which are the most important species at these two sites, appeared grouped together. chrysomya albiceps, chrysomya megacephala and hemilucilia semidiaphana, the main species at site a, also appear together.

Abstract: monthly collections were made using two traps 5 m apart exposed for 48h, containing sardines and installed at points: a at the edge (500 m from the entrance of the reserve); b 1200 m from the entrance and 1000 m inside the forest; and c 1700 m from the entrance and 500 m inside the forest. the purpose was to evaluate the abundance and richness of calliphorid species as a function of the environmental conditions using pearson's correlation, compare the richness of the areas using anova and tukey's test, compare the abundances of the areas by the kruskal-wallis test, and also assess the possible influence of the anthropic presence. rare, intermediary and common species were identified. the collection totalized 8515 calliphoridae belonging to 26 species, with a predominance of females. none of the 13 species considered common presented a correlation between abundance and temperature: only cochliomyia hominivorax (coquerel) and chrysomya megacephala (fabricius) were correlated with humidity and only mesembrinella semihyalina mello with precipitation. this parameter was the only climatic variable correlated with richness. the greatest abundance and richness of calliphorids occurred in september 2006. from the 13 common species, seven were considered synanthropic, indicating the effect of anthropic action in this site.

Abstract: organogenesis induction from internodal segments of yellow passionfruit (passiflora edulis f. flavicarpa) was obtained in a medium supplemented with 1.0-4.0 mg l-1 benzylaminopurine (bap). callus proliferation and adventitious shoot development were analyzed by light and scanning electron microscopy. callus proliferation and adventitious shoots were observed simultaneously and continuously, with asynchronous development of shoots in the explants. proliferation of callus was observed in the explant cut ends in all treatments, including the control. the results show that concentrations of 1.0 or 2.0 mg l-1 bap gave better rate of organogenesis. higher concentrations were efficient for the induction of adventitious buds and, were, however, detrimental for subsequent shoot development. growth and rooting of shoots were obtained in half strength medium without growth regulators.

Abstract: La hormiga loca (HL) representa un problema ambiental, social y economico ante el cual se ha planteado la necesidad de realizar la busqueda de enemigos naturales que puedan convertirse en reguladores de sus poblaciones. Con este fin, se hizo un reconocimiento de estos, mediante la observacion visual y captura de la HL, y otras hormigas en dos zonas: en el Colegio (C/marca) como representante de una zona otrora invadida por altas poblaciones de la plaga, y el valle geografico del rio Cauca. donde hay sectores actualmente afectados por esta. En elColegio, no se capturò a la HL, pero si a un buen niimero de especies pertenecientes a otros generos y subfamilias. Bajo estas condiciones, no hubo forma de detectar a los enemigos naturales, pero si concluir que hubo un restablecimiento del equilibrio junto con la desaparicion de la HL, hasta el momento sin explicacion clara. En el valle geografico del rio Cauca no se encontraron entomopatogenos ni parasitoides distintos al cicaro Macrodinychus sellnicki, que se hallo parasitando desde 0 hasta 82% de las pupas de la HL, en el ingenio Risaralda y en INCAUCA S.A., respectivamente. En observaciones de campo se logro detectar a la hormiga legionaria Labidus pos. coccus, depredadora especialmente de hormigas, en nidos de la HL. Ademas, en el ambiente menos distuibado de los estudiados, la madrevieja La Trozada, se encontrò la presencia de la HL con otras hormigas nativas, en un estado en donde la competencia por los recursos se constituye en un elemento importante para la regulacidn de las poblaciones de la plaga. Estas situaciones sugieren que las altas infestaciones de la HL no son permanentes y su duraciòn esta influenciada por las caracteristicas propias de los sitios que invade. La importancia de los enemigos naturales radicaria en debilitar las poblaciones de la HL, permitiendo que sus competidores, especialmente otras hormigas. terminen por minimizarlas en la zona afectada. The crazy ant (CA) has become an environmental, social and economic problem and there is a need to explore for natural enemies that might regulate its populations. With that objective, a survey was conducted by means of visual observation and captures of CA and other ants in two zones: El Colegio (Cundinamarca) representing a zone once highly infested by this pest and the Cauca River Valley where there are areas currently affected by the CA. CA was not caught in El Colegio but a large number of ant species belonging to other genera and subfamilies were collected. Under these conditions it was not possible to detect natural enemies, but equil

Scientia Agricola , 2000,
Abstract: Organogenesis induction from internodal segments of yellow passionfruit (Passiflora edulis f. flavicarpa) was obtained in a medium supplemented with 1.0-4.0 mg L-1 benzylaminopurine (BAP). Callus proliferation and adventitious shoot development were analyzed by light and scanning electron microscopy. Callus proliferation and adventitious shoots were observed simultaneously and continuously, with asynchronous development of shoots in the explants. Proliferation of callus was observed in the explant cut ends in all treatments, including the control. The results show that concentrations of 1.0 or 2.0 mg L-1 BAP gave better rate of organogenesis. Higher concentrations were efficient for the induction of adventitious buds and, were, however, detrimental for subsequent shoot development. Growth and rooting of shoots were obtained in half strength medium without growth regulators.
About group digital signatures
Adriana Cristina Enache
Journal of Mobile, Embedded and Distributed Systems , 2012,
Abstract: Group signatures try to combine security (no framing, no cheating) and privacy(anonymity, unlinkability).A group digital signature is a digital signature with enhanced privacy features that allows members of a given group to anonymously sign messages on behalf of the group, producing a group signature. However, in the case of dispute the identity of the signature's originator can be revealed by a designated entity (group manager). The present paper describes the main concepts about group signatures, along with a brief state of the art and shows a personal cryptographic library implemented in Java that includes two group signatures.

Abstract: the aim of this study was to estimate the additional cost of treatment of a group of nosocomial infections in a tertiary public hospital. a retrospective observational cohort study was conducted by means of analyzing the medical records of 34 patients with infection after total knee arthroplasty, diagnosed in 2006 and 2007, who met the criteria for nosocomial infection according to the centers for disease control and prevention. to estimate the direct costs of treatment for these patients, the following data were gathered: length of hospital stay, laboratory tests, imaging examinations, and surgical procedures performed. their costs were estimated from the minimum values according to the brazilian medical association. the estimated cost of the antibiotics used was also obtained. the total length of stay in the ward was 976 days, at a cost of us$ 18,994.63, and, in the intensive care unit, it was 34 days at a cost of us$ 5,031.37. forty-two debridement procedures were performed, at a cost of us$ 5,798.06, and 1965 tests (laboratory and imaging) were also performed, at a cost of us$ 15,359.25. us$ 20,845.01 was spent on antibiotics and us$ 1,735.16 on vacuum assisted closure therapy, microsurgical flaps, implant removal, spacer use, and surgical revision. the total additional cost of these cases of hospital infection in 2006 and 2007 was of us$ 91,843.75. based on that, we demonstrate that the high cost of treatment for hospital infections emphasizes the importance of taking measures to prevent and control hospital infection.

Abstract: Our aim was to determine the epidemiological characteristics, the resistance patterns and the spread of Gram negative bacteria related to colonization of patients in adult Intensive Care Units. Methods: A prospective cohort of patients colonized and/or infected with Gram negative bacteria was conducted at two adult ICUs from hospitals in Brazil (April 2012 to February 2013). Nasal, groin and perineum swabs were performed. Samples were incubated on MacConkey and cetrimide agar (48 h at 37) and identification tests (Vitek-BioMérieux), antibiogram (Bauer-Kirby method), Carba NP test, Polymerase Chain Reaction (PCR) and sequencing were performed. The patterns of resistant microorganisms were compared by rep-PCR (Diversilab). Results: There were 53 cases of colonization. In these cases, we identified imipenem-resistant Acinetobacter baumannii (51%), Pseudomonas aeruginosa (32%), Klebsiella pneumoniae ESBL (38%) or imipenem resistant (5.6%). The use of antimicrobials and medical devices were related to colonization (p < 0.05). The resistance patterns expressed by Klebsiella
