1. A dispensing holder for foil packaged on a roll within a box of square cross-sectional shape, comprising an elongated structure of substantially uniform cross-sectional shape throughout its length having a rectilinear pocket adapted to receive the foil package, said pocket being formed by a ba...
This enabled a relation between intrinsic viscosity and number average molecular weight to be established for polystyrenes with chain length distributions of this functional form. Assuming this form of chain length distribution to remain unaltered on degradation, it was possible to estimate the average ...
The seed treatment of tomato plants was conducted with immersion in SA solutions for 5 minutes under the concentrations of 0.5; 1.0; 1.5 and 2.0 mMe and control (distilled water). Subsequently, we showed them in expanded polystyrene trays containing the substrate Plantmax Florestal, previously ...
The seeds were sown in polystyrene trays containing substrate inoculated with R. solani and kept in a growth chamber with 12 hours photoperiod and temperature of 25 ± 2 °C for 14 days. After this period we evaluated the survival of seedlings, leng...
