Observation of CR Anisotropy with ARGO-YBJ
The measurement of the anisotropies of cosmic ray arrival direction provides
important informations on the propagation mechanisms and on the identification
of their sources. In this paper we report the observation of anisotropy regions
at different angular scales. In particular, the observation of a possible
anisotropy on scales between 10 and 30
suggests the presence of unknown features of the magnetic fields the charged
cosmic rays propagate through, as well as potential contributions of nearby
sources to the total flux of cosmic rays. Evidence of new weaker few-degree
excesses throughout the sky region R.A. is
reported for the first time.Comment: Talk given at 12th TAUP Conference 2011, 5-9 September 2011, Munich,

The Determinants of Residential Water Demand Empirical Evidence for a Panel of Italian Municipalities
We present empirical evidence on the determinants of residential water demand for one Italian region, Emilia-Romagna, by using municipal panel data. The estimated water demand price elasticity is negative, showing values between -0.99 and -1.33, never significantly different from one, if we consider different specifications without and with additional socio-economic factors. Income results associated to a positive elasticity, though lower than one. The role of other socio-economic territory-specific determinants is less relevant, with the exception of altitude. The relative high value of price elasticity is deemed consistent with the higher level of Regional water prices compared to the national average

Release of mutagens from finished leather.
Extracts of a leather widely used in the furniture and dress-making industries were tested for their mutagenic activity in the Salmonella/microsome assay. Extracts obtained after vigorous treatment of leather samples in a Soxhlet apparatus with toluene or ethanol were mutagenic in strain TA98 of S. typhimurium in the absence of S9 mix. The analysis of extracts of leather at various intermediate stages of processing showed that the mutagenic activity appeared after the coloration process. The responsible compound was identified to be an azo dye (Color Index: Acid Brown 83) whose mutagenic potency was about 4 revertants/micrograms
