This research aimed to test particleboard with leucena (Leucaena leucocephala) wood particles and polyurethane resin castor oil based. The response variables are: modulus of rupture (MOR), internal adhesion (AI), apparent density (dap) and wood moisture content (um). The experiments were developed based on the methodological procedures of the ABNT NBR 14810:2002 standard. The particleboards were manufactured by hot-pressing at 4MPa and 90°C, using timber particles with 5% of moisture content and 10% of monocomponent and bicomponent polyurethane resin. The higher moisture content was achieved when the monocomponent polyurethane resin was used. The bicomponent polyurethane resin provided a percent increase of 43.7% and 22.7% on the modulus of rupture and apparent density, respectively, when compared to the standard limit. The internal adhesion of the panels manufactured with monocomponent resin was 2.45 times higher than the standard limit. The confidence interval between means revealed that the internal adhesion and apparent density exhibited statistical equivalence. A good correlation between the internal adhesion and apparent density was found, for this reason it was possible to estimate the internal adhesion of the panels based on the apparent density data.

The aim of the study was to estimate the prevalence of Babesia bovis and Babesia bigemina in water buffaloes of the Marajó Island, State of Pará, Brazil. We used an indirectenzyme- linked immunosorbent assay (iELISA), with total antigen containing proteins outer surface, and polymerase chain reaction (qPCR), involving the use of SYBR Green based on amplification of a small fragment of the cytochrome b gene. The prevalence of positive animals in iELISA to B. bovis B. bigemina and mixed infection was 24.87% (199/800), 20.75% (166/800) and 18.75% (150/800), respectively. Using the PCR, the presence of B. bovis wasdetected in 15% (18/199) and B. bigemina in 16% (19/199) of animals, and of these, 58% (11/19) presented co-infected by the two agents. The results show a low prevalence of antibodies anti-B. bovis and anti-B. bigemina in water buffaloes from Marajó Island. However, it was observed that the agents of bovine babesiosis circulate in buffaloes, and these may act as reservoirs.
