15. Early cephalometric characteristics in Class III malocclusion
OBJECTIVE: Early identification of craniofacial morphological characteristics allows orthopedic segmented interventions to attenuate dentoskeletal discrepancies, which may be partially disguised by natural dental compensation. To investigate the morphological characteristics of Brazilian children with Class III malocclusion, in stages I and II of cervical ve

16. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an

17. Caracterização de germoplasma de soja quanto aos teores de proteína, óleo e ácidos graxos / Characterization of soybean germplasm for protein, oil and fatty acids contents
Soybean is currently the most prominent crop in the Brazilian production of grains. Its main products include oil and meal, which have been used for the production of food and animal feed. The high protein contents represent the main attraction of soybean use in diet. Furthermore, soybean oil has also been used in the production of biodiesel. These industria

18. The reproductive biology of the plata pompano, Trachinotus marginatus (Teleostei: Carangidae), in southern Brazil
The Plata pompano, Trachinotus marginatus (Cuvier, 1832), is an endemic carangid of the Southwestern Atlantic Ocean, occurring from Rio de Janeiro to Uruguay. This study describes the reproductive period, spawning type, the size at first gonadal maturation and the length-weight relationship of individuals sampled from landings of the artisanal and commercial

19. Population structure and reproductive behavior of Sinaloa cichlid Cichlasoma beani (Jordan, 1889) in a tropical reservoir
The population structure and reproductive condition of the Sinaloa cichlid Cichlasoma beani from samples obtained from June 2000 to July 2001 were determined. Samples in the first week each month from the largest trader of tilapia in the Aguamilpa Reservoir in Mexico and were caught in gillnets (9.6 and 11.4 cm stretch-mesh size). Of 596 specimens, there wer

21. Characterization for plant height and flowering date in the biological species oat.
The use of wild oat races in artificial hybridization with cultivated oat (Avena sativa L.) has been used as a way of increasing the variability. This work aimed to identify the variability for plant height and flowering date of groups of cultivated oat genotypes, wild introduction of A. fatua L. and segregating populations of natural crosses between A. sati

22. Key locations for soybean genotype assessment in Central Brazil.
The objective of this work was to identify key locations for the establishment of soybean (Glycine max) genetic breeding programs, in the Central Region of Brazil. Grain yield data of three maturity groups of soybean genotypes, from regional trials conducted over three years, at 18 locations in Brazilian Cerrado were used. A key location for the early pha
