Correlação da produtividade do feijão com a resistência à penetração do solo sob plantio direto

The soil mechanical resistance to penetration (PR) has great influence on vegetative development as the root growth and the crop productivity change in inverse proportion. Thus, the objective of this research was to study correlation between the bean grain productivity and the PR in an Oxisol cultivated for four years in no-tillage system at FEIS/UNESP. The attributes PR and yield were determined in a regular grid with 119 sample points. The PR was determined in the layers of 0-0.05, 0.05-0.10, 0.10-0.15, 0.15-0.20 and 0.25-0.30 m. The results were submitted to procedures of descriptive statistics, linear correlation and geostatistic analysis. The linear correlation between the yield and PR was practically null, as in all soil layers investigated it showed determination coefficients (R2) smaller than 0.03 and not significant. The geostatistic analysis showed moderate structure of spatial dependency for PR in the layers of 0.05-0.10 and 0.10-0.15 m, and strong for yield; however, the conjugate spatial analysis of such attributes showed no correlation, therefore, the spatial variability of PR did not influence the yield.

Determination of crude protein, crude fiber and crude fat in twenty-five genotypes of kale (B. oleracea var. acephala)

The aim of the study was to determine the percentage of crude protein, crude fiber and crude fat (ether extract) of 25 genotypes of kale from the Germplasm Bank of Instituto Agronômico de Campinas and of one genotype grown in the region of Jaboticabal-SP. The plants were cultivated in the field, and the leaves after collection were pre-dried in a convection oven at 65°C for 72 h. Afterward, the leaves were analyzed for crude protein, crude fiber and crude fat (ether-soluble materials). Significant differences were detected among the different genotypes for all the characteristics examined. Of the genotypes studied, six showed more than 30% crude protein: HS-20 (32.56%), Comum (31.70%), Couve de Arthur Nogueira 2 (31.16%), Pires 2 de Campinas (30.63%), Manteiga I-916 (30.36%), and Manteiga de Ribeirao Pires I-2446 (30.03%). In relation to crude fiber, the highest percentage was seen in the genotype Manteiga de Mococa (10.92%), differing significantly from the other genotypes studied. With regard to crude fat, the highest percentage was found in the genotype HS-20 (3.72%), and Pires 1 de Campinas (3.34%). Of the genotypes tested, HS-20 stood out among the others, showing both the highest percentage of protein and fat.

Variáveis epidemiológicas e alterações clínicas, hematológicas e urinárias em cães sororreagentes para Leptospira spp

In order to determine antibodies anti-Leptospira spp. in dogs from Botucatu-SP with a clinical suspicion and the risk factors for this zoonosis, as well possible hematological and urine alterations were collected blood samples from 248 dogs. The diagnostic test performed was the Microscopic Agglutination Test (MAT) with 29 serovars of leptospires. Titers were considered reagent ≥200 and detected in 17.7% (44/248) of the dogs. The most frequent serovars were Autumnalis (20.5%); Pyrogenes (18.2%); Gryppothyphosa (15.9%); Canicola (13.6%); Bratislava and Copenhageni (9.1%); Andamana (4.5%) and Djasiman (2.3%). Regarding the analysis of the epidemiological questionnaire administered to owners of the dogs, there was statistical significance for sex, age and presence of rats at home, showing that, by logistic regression analysis, only the sex variable was been significantly associated to the presence of antibodies anti-Leptospira. The levels of urea and creatinine were significantly increased in the group of animals reagents to the Microscopic Agglutination Test, showing the renal damage in these animals and decreased hemoglobin level.

Calcium aluminate cement: Used in bone defects induced in the femur of rabbits

The patterns of the calcium aluminate cement in bone defects experimentally induced in the femur of 12 New Zealand White rabbits were evaluated. The animals were distributed in three experimental groups, corresponding to postoperative observation periods of 15 (G15), 30 (G30) and 60 (G60) days. Clinical, surgical, radiographic and histological appraisals were made to observe the osteoinductor and osteoconductor potential of the biological material, as well as the bone integration. The calcium aluminate cement formulation was biocompatible, but has not acted as a osteoconductor or osteoinductor.
