    Notes: Handling stress and exposure to the herbicide Stam® M-4 (Propanil) were associated with an exponential depletion of the rodlet cells (RC) in the bulbus arteriosus of chub Leuciscus cephalus. Structural changes of the RC in herbicide-exposed fish were encountered, including the occurrence of myeloid bodies in the cytoplasm of the RC of the intestine, various degrees of rodlet degeneration and high vacuolization in the cytoplasm of RC in almost all examined organs of exposed chub.

    Notes: Abstract We have studied the geometry and energy involved in the interactions between adsorbed molecules and paper substrate, over a wide range of partial pressures. A two-dimensional virial equation of state was employed to evaluate the extent of interactions by the compressibility factor (Z). Data of H-bonded molecules (water and butan-1-ol) and of more weakly interacting ones (n-decane and dioxane) were selected from the literature. At low surface coverage, the compressibility factor Z exceeds 1, showing a deviation from ideality due to interactions, and reaches a maximum at a value close to the BET monolayer. As preliminary results we have measured by means of a differential microcalorimeter (Calvet) at 25

    Notes: Abstract Prehistoric metal findings from Liguria are numerous, however, even though there were many metalliferous mines, the metal-working sites have not yet been ascertained. This work discusses results on some metal objects from different archaeological sites in Liguria. The objects examined were: 1) two melting drops 2) an axe, and 3) a knife. The physico-chemical investigation techniques employed were: X-ray diffraction, radiography, microdrawing method, followed by optical and electron scanning microscopy observations, differential thermal and thermogravimetric analyses to characterize the clay core found inside a socketed knife.
