O presente trabalho apresenta equações de estimativa da radiação fotossinteticamente ativa global () e difusa () em função das respectivas radiações global () e difusa () do espectro solar total, bem como a estimativa da fração PAR difusa da PAR global () em função do índice de transmissividade atmosférica (). A base de dados foi adquirida no período de 01/06/1999 a 31/09/2000 na Estação de Radiometria Solar da FCA-UNESP, Botucatu. Foram utilizados dados adicionais, diferentes dos utilizados na geração dos modelos, de forma a possibilitar uma validação adequada dos modelos propostos.

This survey was conducted with the objective of developing and adapting diagnostic techniques in neurology for non-human primates, of the species Alouatta guariba Geoffroy Saint-Hilaire, 1812 (howler monkey) healthy and kept in captivity. Physical-chemical analyses were carried out in cerebrospinal fluid and its pressure measurement in the cisterna magna. Eight animals were used for the analysis of cerebrospinal fluid. In all procedures, were used chemical restraint and anesthesia with ketamine, xylazine and association of midazolam and inhalational anesthesia with isoflurane for carrying out the spinal tap. The cerebrospinal fluid analysis showed average values: protein: 16.92±9.84; glucose: 131.25mg/dL±106.7; pH: 8.37±0.69; nucleated cells: 0.5/mm³±0.75; red blood cells: 49.37/mm³±111.76 and CSF cisternal pressure: 7.37cm H2O±1.77. This study demonstrated the safety and efficacy of cerebrospinal fluid collection in the cisterna magna of Alouatta guariba, and the reference values for the specie.

The objectives of this study were to evaluate the characteristics of ruminal fluid, blood gas analysis, pedometer activity and suclinical laminitis occurrence, through the presence of secondary foot diseases in high production dairy cows, from a commercial herd. 200 Holstein cows originating from the same farm, located in Araçatuba/SP, Brazil, were divided into four groups, which are established from the daily milk production. Initially clinical examination of the cows was procedure, followed by sampling of rumen fluid, by esophageal tube. Fluid was evaluated for pH, color, odor, consistency, sedimentation, flotation and methylene blue reduction test. Venous blood samples were also collected for blood gas analysis, in addition to collecting data from pedometrics (number of steps) and daily milk production. Data were tabulated and submitted to correlation analysis. No animal had reported changes in rumen pH. Non-acid base imbalance were found, since the values of blood pH, PCO2, TCO2, HCO3- and BE were normal during hemogasimetric analysis. The pedometric was effective as a screening method to cows with foot diseases. It demonstrated reduction in the number of steps due to pain, correlated with lower milk production. However, the identification of foot lesions was only possible through specific digital clinical examination. The occurrence of 49.5 % of herd foot problems was due to the risk factors present in the farm. The abrasive concrete and inadequate facilities, also associated with the possible occurrence of sub-acute ruminal acidosis, were observed as risk factors. However, sub-acute ruminal acidosis was undiagnosed by the methods used. The correlation between the values of ruminal pH, and blood gas analysis pedometrics showed efficient for the early diagnosis of foot diseases and also in establishing the etiology of these diseases. Subclinical laminitis occurred primarily in cow's herd, considering the multifactorial etiology of this disease, occurrence and distribution of foot diseases diagnosed.

Avaliou-se a resposta de fase aguda através da concentração das proteínas de fase aguda (PFA) no soro sanguíneo e no líquido peritoneal de vinte e um equinos, hígidos e submetidos à obstrução intestinal experimental, distribuídos em quatro grupos: obstrução de duodeno - GD (n=6), íleo - GI (n=6), cólon dorsal esquerdo - GM (n=6) e controle instrumentado - GC (n=3). Foram colhidas amostras de sangue e líquido peritoneal e, após centrifugação e fracionamento, as proteínas de fase aguda foram separadas por eletroforese em SDS-PAGE. Identificaram-se as proteínas IgA, ceruloplasmina, transferrina, albumina, IgG, haptoglobina, α1-glicoproteína ácida e P24, no soro e no líquido peritoneal. Houve aumento nas concentrações sérica e peritoneal de todas as PFA, sendo mais evidente no líquido peritoneal e nos animais obstruídos. O fracionamento eletroforético das PFA no líquido peritoneal é mais eficaz no diagnóstico de processos inflamatórios abdominais, quando comparado ao sérico.

The objective of this study was to evaluate the responses of sugar cane subject to water stress by photosynthetic pigments (chlorophylls a, b, total a + b, ratio chlorophylls a/b and carotenoids) and verify the use of SPAD index as a cultivar differentiation tool. The experiment was carried out in a greenhouse, where four cultivars (IACSP95-5000, RB835054, RB928064 and SP80-3280) were grown in pots. After 65 days of planting, two treatments were implemented, i.e., with no stress (-D) and with water stress (D +). Cultivars of sugar cane respond differently in relation to photosynthetic pigments when subjected to water deficit. Cultivars IACSP95-5000 and RB928064 have less effect of drought, that is attributed to the ability of maintaining the chlorophyll and carotenoid content, as well as higher SPAD index values under this condition. Water stress affects with more intensity the cultivars RB835054 and SP80-3280 due to higher reductions in photosynthetic pigments and SPAD index. SPAD index is correlated with chlorophyll and carotenoid content in sugar cane and can be used as a technique for selecting tolerant cultivars to drought in breeding programs.
