    Notes: Abstract This article presents an example of a tracing experiment using two bacteriophages, T7 and f1, and a fluorescent dye (naphthionate), in a saturated porous environment. The test field was equipped with an injection borehole and 22 sampling piezometers set in three concentric half-circles. The distribution of permeabilities and the thickness of the aquifer were indirectly determined by Radio-Magneto-Tellury (RMT, 12–240 kHz). The results reveal a good correlation between the distribution of permeabilities obtained by RMT and the breakthrough curves and speed of migration of all three tracers. The restitution levels are far superior (by two to three orders of magnitude) in the more permeable zones, as opposed to those observed in th piezometers situated in less permeable areas. The speed of migration of the biological tracers is much greater than that of the naphthionate. In the most extreme case, the T7 bacteriophage migrated about 3.15 times faster than the chemical solution. These results indicate that bacteriophages are able to travel considerable distances along permeable gravel channels. They may be used as biological tracers and as models for the migration of pathogenic viruses. The simultaneous use of tracing techniques and appropriate geophysical methods leads to a better knowledge of the hydrogeological parameters of the underground terrain. This combination allows for a better interpretation both of the speeds of migration and of the maximal concentrations of the tracers, and thus considerably increases the interpretability of hydrogeological impact studies.

    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

    Description / Table of Contents: Sommario Abbiamo esaminato il trattamento farmacologico dell'attacco acuto, usato da 200 pazienti sofferenti di emicrania senza aura (criteri IHS 1988), visitati nel periodo 1989–1991. È stata raccolta una dettagliata analisi farmacologica sulle terapie d'attacco usate dai pazienti nel corso della loro storia cefalalgica precedentemente alla prima visita presso il nostro ambulatorio. Sono state studiate le seguenti variabili: tipo di farmaco usato, dosaggio e via di somministrazione, efficacia del trattamento, frequenza e tipo degli effetti indesiderati; questi parametri sono stati confrontati con le linee guida della Società Italiana per lo Studio delle Cefalee (SISC, 1993). I farmaci più comunemente usati sono gli antiinfiammatori non steroidei; abbiamo osservato un analogo uso delle associazioni, in particolare propifenazone ed acido barbiturico. I pirazolonici propifenazone ed amidopirina, non consigliati nelle linee guida, sono anch'essi largamente usati. Il nostro studio evidenzia il fatto che l'utilizzo corrente dei farmaci differisce in molti aspetti da quello suggerito dalle linee guida.
    Notes: Abstract We assessed the attack drugs taken by 200 migraine without aura patients (International Headache Society criteria, 1988) between 1989 and 1991. A detailed pharmacological history regarding the acute attack therapy adopted up until our initial visit was gathered, including the type of drug used, dosage, administration route, the time of starting therapy, treatment efficacy, and the frequency and types of undesirable effects, all of which were subsequently compared with the guidelines (1993) of the Italian Society for the Study of Headache (SISC). The most commonly used are non steroidal anti-inflammatory drugs (NSAIDs). We observed a similar high frequency in the use of combinations, particularly prophyphenazone and barbituric acid. The pirazolones, such as noramidopyrine and prophyphenazone, are also widely used as single agents, even though they are not considered by the guidelines. Our study underlines the fact that current drug use differs in several respects from the guidelines.
