1. ULTRASOUND-ASSISTED TRANSESTERIFICATION OF SOYBEAN OIL USING COMBI-LIPASE BIOCATALYSTS
Abstract We applied ultrasonic technology for the transesterification of soybean oil catalyzed by a mixture of lipases (combi-lipase: 75 % Novozym 435; 10 % Lipozyme TL-IM; and 15 % Lipozyme RM-IM), verifying the effects of ultrasonic amplitude, pulse conditions, the ethanol:oil molar ratio, enzyme concentration, and the influence of solvent (tert-butanol on

2. Inferences on the effects of selection for feed conversion over meat quality traits in broiler
ABSTRACT: The intense selection process for economic traits conducted by the poultry breeding programs has been caused several changes in broiler meat quality. A database belonging to a selection program of a broiler male line was used to estimate heritability and genetic correlations for feed conversion ratio and meat quality traits, which were: initial and

3. ENZYMATIC BIODIESEL SYNTHESIS FROM ACID OIL USING A LIPASE MIXTURE
The conventional biodiesel production process has some disadvantages. It is necessary to use refined vegetable oils with low free fatty acids (FFAs) content. An alternative route is to use low-cost acid oils in an enzymatic process. The use of lipases allows simultaneous esterification of FFAs and transesterification of triglycerides present in raw material

4. Toxicidade e efeitos residuais de iscas tóxicas à base de espinosinas sobre a mosca-das-frutas sul-americana
Resumo: O objetivo deste trabalho foi determinar a concentração e o tempo letal (CL e TL) de espinosade e espinetoram, associados a diferentes atrativos alimentares, e seus efeitos residuais sobre a mosca-das-frutas sul-americana (Anastrepha fraterculus). As iscas tóxicas foram ofertadas em oito concentrações (2, 6, 14, 35, 84, 204, 495 e 1.200 mg L-1),

5. Reproductive biology of Sympterygia bonapartii (Chondrichthyes: Rajiformes: Arhynchobatidae) in San Matías Gulf, Patagonia, Argentina
ABSTRACT This study estimates and analyses the reproductive parameters and cycle of Sympterygia bonapartii in San Matías Gulf, northern Patagonia, Argentina. A total of 827 males and 1,299 females were analysed. Males ranged from 185 to 687 mm of total length (TL) and females from 180 to 742 mm TL. Sexual dimorphism was detected; females were larger, heavie

6. TOXICIDADE DE ÓLEOS ESSENCIAIS DE Eucalyptus spp. PARA O CONTROLE DO CUPIM SUBTERRÂNEO Coptotermes gestroi (WASMAN)
RESUMO O cupim subterrâneo Coptotermes gestroi (Wasman) (Isoptera: Rhinotermitidae) é considerada uma das principais espécies-praga, em ambiente urbano, na região Sudeste brasileira. Para o controle dessa praga recomenda-se o uso de inseticidas químicos, mas esse controle torna-se problemático em áreas urbanas, devido aos riscos de intoxicação da po

7. Desempenho de novilhas de corte em pastagem natural sob pastoreio contínuo e rotativo no outono-inverno
O objetivo foi avaliar o desempenho de novilhas de corte em pastagem natural sob pastoreio contínuo e rotativo no outono-inverno. Os tratamentos foram distribuídos em um delineamento inteiramente casualizado, conduzidos utilizando a massa de forragem acima de oito cm e 50% da massa de lâminas foliares das touceiras. Os animais foram novilhas Brangus com p

8. Reproductive studies of Anchoa marinii Hildebrand, 1943 (Actinopterygii: Engraulidae) in the nearby-coastal area of Mar Chiquita coastal lagoon, Buenos Aires, Argentina
The aim of the present study provides the first results on the reproductive biology of the anchovy, Anchoa marinii, in a nearby-coastal area of Mar Chiquita coastal lagoon, 37º32'00"S 57º19'00"W, Argentina. To perform this, we employed mainly female gonads, at both microscopic and macroscopic levels. The oocyte diameter distribution and the microscopy anal

9. Utilization of immobilized lipases as catalysts in the transesterification of non-edible vegetable oils with ethanol
This work reports the use of commercially available immobilized lipase preparations (Novozym® 435 and Lipozyme TL IM, both from Novozymes, and Lipase PS IM from Amano) as catalysts in the transesterification reaction of different alkyl-chain triglycerides with ethanol. The ethanolysis of native oils from Brazilian Amazon plants andiroba (Carapa guianensis),

10. Leukocytosis, muscle damage and increased lymphocyte proliferative response after an adventure sprint race
The effect of an adventure sprint race (ASR) on T-cell proliferation, leukocyte count and muscle damage was evaluated. Seven young male runners completed an ASR in the region of Serra do Espinhaço, Brazil. The race induced a strong leukocytosis (6.22±2.04×103 cells/mm3 before vs 14.81±3.53×103 cells/mm3 after the race), marked by a significant increase

12. Longer is not always better: The influence of beach seine net haul distance on fish catchability
The aim of this study was to compare the influence of different haul distances of a codend beach seine on the catchability of fish in a surf zone. Two different surf zone sites (A and B) at the Cassino Beach (Rio Grande do Sul, Brazil) were sampled at three different distances, parallel to the beach (30, 60, and 90 m). Starting 40 m from the beach line, diag
