Abstract

Ecological regions or ecoregions derive from ecological classification of land and represent broad and discrete ecologically homogeneous areas within which natural communities and species interact with the physical elements of the environment. The aim of this paper is to define the ecoregions of Italy, southern Europe, based on a robust methodological process for classification and mapping. The ecoregions of Italy comprise 2 Divisions, 7 Provinces, 11 Sections and 33 Subsections and constitute the first comprehensive ecological classification of the country that integrates accurate and updated cartographies and knowledges on climate, vegetation, land units and biogeography. This classification has the strength to be adopted as a proper framework for ecological modelling, biodiversity conservation policies and sustainable territorial planning at the national and subnational level.

6. Semi-global mechanisms for the oxidation of diammonium phosphate impregnated wood

Author

Branca C. and Di Blasi C

Abstract

Thermogravimetric measurements in air of fir wood impregnated with diammonium phosphate in the concentration range 2-20% and heating rates between 5 and 20 K/minshowthe existence of three sequential stages: wood decomposition, induction and char oxidation. The additive causes an anticipation in the decomposition stage up to about 100 K, a reduction in the maximum rate up to a factor of three and an increase in the charred solid residue from about 30 to 60%. The total duration of the induction and oxidation stages is also increased. The experimental curves are interpreted by either a three-step mechanism (one reaction for each stage) or a seven-step mechanism (three reactions for decomposition and two reactions for the induction and oxidation stages). The estimated kinetic parameters are independent from the heating rate but vary with the diammonium phosphate concentration. However, for both mechanisms, the activation energies of the various steps remain practically constant except for the decomposition of the cellulose component or the decomposition step, depending on the complexity of the mechanism.

10. Influences of the Chemical State of Alkaline Compounds and the Nature of Alkali Metal on Wood Pyrolysis

Author

Di Blasi C., Galgano A., and Branca C

Abstract

The pyrolysis of a packed bed of fir wood particles, after impregnation with KOH, is investigated. For a heating temperature of 800 K, maximum variations in the pyrolysis characteristics are observed for KOH concentrations in wood below 1%. Decomposition temperatures become lower (35-70 K), and conversion times are rapidly more than halved. Also, the char, water, and gas yields increase (factors of 1.4, 1.6, and 1.7, respectively) at the expense of liquid-phase organic products. Levoglucosan presents a very steep decay, whereas the diminution in hydroxyacetaldehyde and acid acetic is much slower, and a wide zone of approximately constant values appears for hydroxypropanone. However, small quantities of KOH in wood (about 0.2-0.6%) are apt to increase the yields of furfuryl alcohol up to a factor 15 and some carbohydrates (3-ethyl-2-hydroxy- 2-cyclopentenone, 3-methyl-2-cyclopentenone, 1-hydroxy-2-butanone) and phenols (phenol, cresols, hydroquinone, guaiacol, isoeugenol-trans, isoeugenol-cis, 4-acetonguaiacol, 4-ethylguaiacol) up to factors of 2-6. Higher KOH concentrations cause a further increase in the yields of char and CO2 associated with a decay to very small yields of all of the organic compounds. Finally, increasing the heating temperature from 600 to 900 K (KOH concentration in wood of about 0.6%) essentially favors devolatilization and cracking of vapor-phase organic products with conversion times roughly reduced by a factor of 6.

45. [Electrophysiologic profiles in a few cases of Wolfram syndrome]

Abstract

The authors have examined some electrophysiologic data in two couples of siblings with Wolfram's syndrome and in the unaffected sister of one of the couples. The results confirment the involvement of some neurologic structures and show up how the Evocated Potentials can disclose a damage in the a.m. structures even lacking clinical features.
