This article analyses and compares the structure of hostile attitudes and aggressive behaviour of two national groups, English and Italian, taking into account the national stereotypes involved. While the two groups do not differ greatly in their overall level and general pattern of scoring on a...

The main aim of this work is to make an economic evaluation of solar energy systems applied to the zootechnic field. As a typical application, a cattle-breeding farm was chosen, with the following energy requirements: stable heating during the cold season, heating of washing water, and the...

Various applications are discussed for the civil use of a device based on the adsorption/desorption of water vapour in a zeolite. Experimental work carried out with a testing system is described. Technical and economical development of such a system depends mainly on the solution of heat- and...

We present a method for dynamic simulation of a two-reactor adsorption heat pump. The operating principle of the system is described and the governing equations are derived, taking into account the efficiencies of the various components. A non-dimensional form of the model shows the important...

The response of an adsorption system to imposed changes in temperature in terms of pressure and uptake variations is analysed. A theoretical model is developed to predict system behavior. Comparisons of experimental data with model results show good agreement.

The aim of the present study was to compare the life cycle, in terms of greenhouse gas (GHG) emissions, of diesel and liquefied natural gas (LNG) used as fuels for heavy-duty vehicles in the European market (EU-15). A literature review revealed that the numerous studies conducted have reported...

The transport sector represents a major item on the global balance of greenhouse gas (GHG) emissions. Natural gas is considered the alternative fuel that, in the short-medium term, can best substitute conventional fuels in order to reduce their environmental impact, because it is readily...

Thermal energy storage (TES) is widely recognized as a means to integrate renewable energies into the electricity production mix on the generation side, but its applicability to the demand side is also possible. In recent decades, TES systems have demonstrated a capability to shift electrical...
