Abstract: modeling clays have been used in several ecological experiments and have proved to be an important tool to variables control. the objective of our study was to determine if fruit color in isolated and grouped displays influences the fruit selection by birds in the field using artificial fruits. data were collected in six plots distributed homogeneously in 3 km long trails with a minimum distance of 0.5 km. we used a paired experimental design to establish our experiments, so that all treatments were available to the local bird community in each plot. overall, red was more pecked than brown and white. isolated red and brown displays were significantly more pecked than others display. even though our study was conducted in small spatial scales, artificial fruits appeared to be efficient in register fruit consumption attempts by bird. although inconclusive about selective forces that sharp the dynamics of fruit color polymorphisms and choice by frugivorous birds, our findings corroborate recent studies wherein birds showed preferences by high- over low-contrast fruit signals.

Abstract: based on the theory of the social representations of moscovici and from the contextualization of the phenomenon of street gang mass robberies, this text proposes to discuss elements that respond to the following questions. why have criminalizing discourses, which claim how dangerous funk fans are, been so evident since the start of the 1990s in rio de janeiro? how do these discourses, which indicate a certain social construction of the funk fan, interfere in the relationship of funk with society? the discussion starts with an understanding of the devices created in the rio de janeiro society of that period for solving the problems with which it saw itself confronted. this is an attempt to understand how, at a particular point in time, the funk fan received a widely disclosed profile as a problem that requires a specific type of intervention.

RGO : Revista Gaúcha de Odontologia , 2008,
Abstract: Objective: To evaluate the effect of dental bleaching on the shear bond strength of enamel. Methods: Fifty molars were selected and divided into five groups (n=10); G1-without bleaching (control); G2-bleached with 10% carbamide peroxide and restored 24h later; G3-bleached with 10% carbamide peroxide and restored seven days later; G4-bleached with 35% hydrogen peroxide and restored a 35% and restored 24h later; G5-bleached with 35% hydrogen peroxide and restored a 35% and restored seven days later. During the 24h and 7-day intervals the test specimens remained stored in artificial saliva, after which the restorative procedures were performed on the enamel. Results: The microshear bond strength test indicated the following results in MPa (ANOVA and Tukey post-hoc): G1-43.15 a (±5.19); G2-31.34 ab (± 4.41); G3-36.66 ab (± 3.11); G4-22.87 c (±3.76) and G5-35.67 ab (± 4.64). Conclusion: Groups G1, G2, G3 and G5 showed no statistical difference and Group G4 (bleached with 35% hydrogen peroxide and restored 24h later) showed diminished bond strength between the bleached enamel and resin composite.

Abstract:
During the industrial fermentation process in the production of fuel ethanol, yeasts are subject to several stressing conditions. The survival and the permanence of strains introduced in the process correlate with the capability of these yeasts in resisting to physical and chemical stresses, as well as their recovering ability to compete with contaminating micro-organisms commonly present in this industrial process. We aim at the selection of Saccharomyces cere visiae strains having this capability and ability. In this sense, cultivations of strains with industrial interest were irradiated with gammas ray at a wide dose interval. Growing curves for the strains were analyzed by means of their relative growth, a new concept here introduced, which allows a better understanding of the growing and recovering processes following radiative stress. It was found that gamma radiation could be used as an alternative method to quantify growing capabilities of S. cerevisiae strains under stressing conditions. It was also shown that this radiological method could be utilized as an additional procedure to select best robust industrial strains. This radiological method simplifies traditional analysis of strain viability, by avoiding the great number of necessary and consecutive fermentation assays.

Insects , 2012, DOI: 10.3390/insects3040930
Abstract: The New World Screwworm, Cochliomyia hominivorax (Coquerel), is one of the most damaging parasites of livestock, causing millions of dollars in annual losses to producers. The fly is an obligate parasite of warm-blooded animals, including humans. After a successful 50-year eradication campaign, C. hominivorax has been eradicated from the USA, Mexico and Central America by an area-wide integrated pest management approach. Recently, Caribbean and South American countries have expressed an interest in this approach. Aiming to support forthcoming projects in these countries, this review describes the main technical components of past and ongoing AW-IPM campaigns against C. hominivorax.

Abstract: Objective: To compare three different regimens of thymoglobulin induction. Methods: One hundred seventy two patients submitted to renal transplantation from a dead donor were divided into three groups according to the total number of thymoglobulin doses used in the post-transplantation surgery: Group 1, until 14 doses – May 2002 to June 2004 (n = 48); Group 2, until 7 doses – July 2004 to December 2006 (n = 57); Group 3, until 4 doses – January 2007 to July 2009 (n = 67). The three groups were compared according to the main outcomes. Results: The main demographic differences among the groups were: greater dialysis time in Group 3 (p < 0.001 for Group 1; and p = 0.04 for Group 2); donor age, greater in Groups 2 and 3 (p = 0.02; p = 0.01, respectively); and cold ischemia time progressively greater from Group 1 to 3: 19.5 ± 5.1 to 24.6 ± 5.7 hours (p < 0.001). In relation to the inhibitor of calcineurin, the relationTac/Csa was 14.6/66.7% in Group 1, 78.9/12.3% in Group 2 and 100/0% in Group 3. Reflecting the increase in cold ischemia time, the incidence of delayed graft function was 64.6%, 68.4% e 82.1% in Groups 1, 2 and 3, respectively (p = ns). The incidence of acute rejection was similar in the three groups: 16.7% (1); 16.3% (2) and 16.4 (3) – p = ns. The prevalence of viremia for cytomegalovirus was 61.7% in Group 1, 66.1% in Group 2 and 83.3% in Group 3 (p = ns). There were no difference related to the number of infected cells with cytomegalovirus in antigenemia, according to the groups, however, patients in Group 3 had an earlier diagnosis: from 64.3 ± 28.5 days in Grup 2, to 47.1 ± 22.5 days, in Group 3, p < 0.001. Survival of the graft in one year was 89.6%, 92.9% and 91.0%, in Groups 1, 2 and 3, respectively (p = ns). The graft function was much better with the lower doses of thymoglobulin: Group 1: 57.0 ± 20.0 mL/min; Group 2: 67.0 ± 18.4 mL/min (p = 0.008); Group 3: 71.2 ± 18.4 mL/min (p < 0.001, Group 1 versus Group 3; p = 0.06, Group 1 versus Group 2). There was a significant reduction in the costs of induction protocol from U$ 7,567.02 to U$ 3,485.56 (p < 0.001). Conclusions: The total number of thymoglobulin doses for immunologic induction could be reduced in a safe and effective way, without a negative impactin graft rejection or survival, preserving renal function and being significantly cheaper.
