Blood samples from lactating, weaned and adult Holstein-Fresiean and Nelore cattle and Murrah buffaloes were tested through the study of hemogram and serum constituents. Red cell and leukocyte counts, and blood pH, fibrinogen, glucose, calcium, and phosphorus levels were similar in cattle and buffalo. Total protein, urea, creatinine, hemoglobin, magnesium, iron and aspartato aminotransferase and alanine aminotransferase activities were higher in buffalo than cattle. Leukocyte counts were higher for weaned Holstein cattle than for Nelore cattle but similar to buffalo and Nelore cattle had the lowest neutrophil counts. Bilirrubin levels were lower for buffalo than for cattle. Phosphatase alkalyne activities were lower for weaned buffalo than for other animals. Gammaglutamyltransferase activities were the highest for lactating and weaned buffalo.

ANALYSIS OF CLAYS BY INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY AFTER CLOSED-VESSEL MICROWAVE-ASSISTED ACID DECOMPOSITION. In this work a closed-vessel microwave-assisted acid decomposition procedure for clays was developed. Aluminum, Ca, Fe, K, Mg, Na, Si, and Ti were determined in clay digestates by inductively coupled plasma optical emission spectrometry. The most critical parameter for total decomposition of clays was the composition of the reagent mixture. The applied power and the heating time exerted a less critical influence. Best decomposition conditions were attained using a reagent mixture containing 4 mL aqua regia plus 3 mL HF and the heating program was implemented in 12 min. The accuracy of the results was demonstrated using two standard reference materials and a paired t-test showed a good agreement between determined and certified values at a 95% confidence level.

The chemical investigation of the leaves of Sorocea bomplandii Baillon (Moraceae) led to the identification of pentacyclic triterpenes, fatty acid ester and isoprenoids. Chromatographyc comparison between the infusion S. bomplandii with that of Maytenus aquifolium - a Celastraceae with proved antiulcer activity - has shown that they have different compositions: the first one is based on sugars and the last one is based on flavonoid glycosides.

The primary objective of this article is to analyze situations with discursive interactions in math classrooms, which may prompt student's understanding of teacher's speech. To analyze the situations with discursive interactions, this study used elements from Bakhtin's theory of language, mainly its concept of comprehension, and introduces the new concept of intermediate comprehension . The data used in a qualitative approach were collected from class observation through video-recorded lessons. The results showed three situations with discursive interactions that contribute to understanding of the school teacher's speech: 1) speech referring to everyday situations; 2) the teacher's speech math in a less rigorous way 3) teacher comparing different mathematical objects.
