Effects of the foal at the milking and dietary supplementation with extra virgin olive oil on jennet milk production
The effects of the foal at the milking and the extra virgin olive oil supplementation in the diet, on the milk obtained by 12 Ragusana jennets were studied. The jennets were each fed 3.5+1.5 kg/d of concentrate+bran, and hay ad libitum. They were divided into 2 equal groups with one group receiving an additional dietary supplement of 100 ml/d of olive oil. Milk was collected at day 20 post foal- ing and every 15-18 d for 5 times. At each collection period jennets were milked 4-times per day. At 07:30 h foals were separated from the jennets and after a 4 hour interval were milked manually (1MNF;1st milking, foal absent). At the end of the 1MNF, each jennet was milked again, with the foals ke…
Environmental and energy performances of a newly installed Dish-Stirling Concentrating Solar Power plant based in Palermo
n the last decade there has been a significant increase globally in solar based electricity production, like those produced from Concentrating Solar Power (CSP) plants. One of the most efficient CSP technologies today is the Dish-Stirling characterized by an efficiency greater than 30%, which may become highly competitive by 2030 according to the International Energy Agency. On one hand, the Dish-Stirling is responsible for high environmental impacts, caused during its production and installation due to their energy consumption and use of energy intensive raw material. On the other hand, no direct emissions are released during its use phase. However, only a careful analysis of the entire li…
Road Thermal Collector for Building Heating in South Europe: Numerical Modeling and Design of an Experimental Set-Up
The combination/integration of renewable energy and storage systems appears to have significant potential, achieving high-energy results with lower costs and emissions. One way to cover the thermal needs of a building is through solar energy and its seasonal storage in the ground. The SMARTEP project aims to create an experimental area that provides for the construction of a road solar thermal collector directly connected to a seasonal low-temperature geothermal storage with vertical boreholes. The storage can be connected to a ground-to-water heat pump for building acclimatization. This system will meet the requirements of visual impact and reduction of the occupied area. Nevertheless, sev…
