Different types of plastic films are used in agriculture to cover silos storing silage. The most important characteristics of a tarpaulin for sealing the silage are: thickness, color and polymer used in the manufacture of the film. The objective of this study is to measure and compare the thickness, the use of two instruments (digital micrometer and digital thickness gauge) in plastic films (polyethylene, polyester and polyester/vinyl). This methodological analysis for the use of micrometer digital, for future use (Agronomy and Veterinary sciences). In comparison the thickness of the three factors. 5% by Tukey test revealed that for polyethylene, there was no significant difference between factors. This methodology is satisfactory for the types of films and range of thicknesses studied.

AIM: To investigate the hepatic capacity to produceglucose during hypoglycemia induced by insulin (HⅡ).METHODS: Livers from 24-h fasted rats whichreceived ip insulin (HⅡ rats) or saline (control rats)were perfused in situ. The gluconeogenic substratesL-alanine (5 mmol/L), L-glutamine (5 mmol/L),L-lactate (2 mmol/L), and glycerol (2 mmol/L) wereemployed. The gluconeogenic activity was measuredas the difference between rates of glucose

The tangerine pathotype of Alternaria alternata is the aetiological agent of Alternaria brown spot on tangerines. In the state of Paraíba, Brazil, its occurrence on “Dancy” tangerine trees is associated with genetic aspects as well as the influence of environmental conditions on reproduction and dissemination within and between populations. The aim of the present study was to evaluate the diversity of isolates of this pathogen using morphophysiological and molecular markers. For the analysis of mycelial growth and sporulation, 30 isolates from different locations were examined at 24-hour intervals until the seventh day, when the spores were quantified. The 30 isolates were characterised based on molecular markers (ISSR) and genetic similarity (Jaccard index). A factor arrangement was used: 30 isolates, four media (ODA, PDA, LEA and V8), three light regimes (continuous dark, alternating light and continuous light) and three temperatures (15°C, 25°C and 35°C), with 12 repetitions. Groups 1, 2 and 3 presented low genetic variability. Group 4 showed high genetic variability of the isolates obtained from the Massaranduba (state of Paraíba-Brazil) producing region and higher mycelial growth and sporulation of A. alternata. The continuous light regime and the temperature 25°C in PDA and V8 media were the ideal conditions for the mycelial growth and sporulation, respectively, of the isolates of A. alternata.
