Thermal and thermo-oxidative stability and kinetics of decomposition of PHBV/sisal composites

2017

The decomposition behaviours of composites made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and sisal were assessed in terms of thermal stability and decomposition kinetics, under inert and oxidative conditions, by means of multi-rate linear non-isothermal thermogravimetric experiments. A statistical design of experiments was applied to study the influence of the addition of sisal (0-10-20-30%wt), the presence coupling agent (Yes/No) and the applied conditions of work (inert or oxidative). An improvement of the thermal and thermo-oxidative stability of PHBV with the addition of sisal was observed for all cases. An accurate methodology based on iso-conversional methods was applied…

La competittività di una destinazione turistica

2013

Measuring destination competitiveness and identifying its determinants are strategic goals for pol-icy makers and tourism stakeholders. In order to do so, the availability of valid and reliable moni-toring tools is requested. In this context quantitative measurement tools, such as composite indi-cators, able to account for complexity and providing easily interpretable measures, represent a useful option. Nowadays composite indicators are commonly used for these aims but some criticism is suggested on how this happens. In this paper we provide some definitions of destination competitiveness and focus on related measurement approaches. In particular, supply-side competitiveness is distinguish…

A proposito della collocazione dell'accento su certi composti di tipo bahuvrihi in vedico e in greco antico

2010

Una discussione sui composti non prescinde mai dalla sistemazione di essi proposta dalla grammatica indiana. Secondo la terminologia da questa introdotta i composti oggi detti possessivi erano chiamati bahuvrihi (es. hiranyaparna "dalle ali d'oro"). Il lavoro è dedicato a una specifica questione relativa alla collocazione dell'accento in certi composti del tipo bahuvrihi. Coincidenze nella collocazione dell'accento sui composti greci e indiani antichi erano già state notate da altri. Gli autori hanno provato a verificare se il fenomeno dell'accentazione del suffisso, riscontrabile nei bahuvrihi del Rig Veda, sia presente e in che termini nel greco antico.

The influence of red worm (E.Foetida) on compost's fertilizing properties

2014

Composting is becoming a more and more common way of biodegradable waste disposal. Composts should be characterized by high content of nutrients and low amount of pollutants. Vermicompost is a compost produced by overpopulated culture of earthworm Eisenia foetida (Savigny 1826). World scientific literature states that vermicompost has a high fertilizing value which often exceeds such value of conventional composts. The results showed that vermicompost has a much higher fertilizing value than the compost produced by the traditional pile method. However, prism vermicompost created with the participation of a less concentrated population of earthworms has an intermediate value as a fertilizer …
