"AGRIGENTO. TOURISM AND TERRITORY: RESOURCES, NEW INSTITUTIONAL ACTORS AND PROJECT PROPOSALS" "Agrigento: turismo e territorio tra risorse, nuovi attori istituzionali e ipotesi progettuali"
Agrigento constitutes one of Italy’s most problematic situations, exhibiting the most striking contrasts: the Valley of the Temples site’s wealth of landscapes and archaeological treasures and a widespread and varied practice of unauthorized building; the beauty and degradation of the city’s historic center besieged by inappropriately tall constructions; the elegance of the 19th century expansion and the growth of abject suburban developments; invasive road works that do not ensure efficient transit. In the sloping area that overlooks the sea, the Valley of the Temples Park is located, an exceptional mix of archaeological treasures and agricultural landscapes, but spoilt in many areas by va…
ChemInform Abstract: Reaction of 2-Acetyltetralone with Some Esters of Benzoic Acid.
In order to investigate the pharmacological screening of a number of pyran-4-ones their synthesis by cyclization with sulphuric acid of the corresponding 1,3,5-triketones has been carried out with high yields. In the course of preparation of the latter the reaction of 2-acetyltetralone with some esters of benzoic acid derivatives has been studied and in particular, for a number of them, an interesting nucleophilic substitution of a chlorine atom with an alkoxy group on a benzenic nucleus has been evidenced.
"La Sicilia punta al business delle rinnovabili"
In Sicilia, dopo oltre un decennio di inadempienze, è stato approvato il Piano energetico regionale che aderisce a politiche di risparmio energetico fondate sul sole, sull'acqua e sul vento e che sbocca investimenti per oltre 30 miliardi di euro.
Subclinical hypothyroidism resulting from autoimmune thyroiditis in female patients with endogenous depression.
Thyroid function and presence of thyroid autoantibodies were assessed in a group of 75 consecutive female patients with mood disturbances and in a group of 38 healthy women of similar age recruited as controls. Nine patients suffered from major (endogenous) depression and 66 from minor (neurotic) depression. The individual patients had normal values of circulating thyroid hormones. Nevertheless, endogenously depressed patients had total serum triiodothyronine (M±SE=1.49±0.09 nmol/l) and both total (83.9±4.3 nmol/l) and free serum thyroxine (13.9±1.1 pmol/l) lower than in the group of minor depressed and in the group of controls (p<0.01, in both comparison). The median value of serum thyrotr…

PVDF based vibration measurements and their correlation with torque estimation in a FOC induction motor drive
This paper presents a study concerning the vibrations generated by an induction motor drive controlled by field oriented control algorithm (FOC). The aim of the study is to identify suitable measurement points and analysis techniques in order to achieve information about vibration generated by an electric drive. Vibrations take origin both by the torque generated by the motor and the motor supply through an inverter, then they are transmitted to neighbouring structures. Torque is estimated on the basis of the estimated flux linkage; vibrations have been both measured and analysed numerically by FEM at two points of the cradle. The numerical and experimental analysis have been carried out fo…
