Impact of climate change and man-made irrigation systems on the transmission risk, long-term trend and seasonality of human and animal fascioliasis i…
2014
Large areas of the province of Punjab, Pakistan are endemic for fascioliasis, resulting in high economic losses due to livestock infection but also affecting humans directly. The prevalence in livestock varies pronouncedly in space and time (1-70%). Climatic factors influencing fascioliasis presence and potential spread were analysed based on data from five mete- orological stations during 1990-2010. Variables such as wet days (Mt), water-budget-based system (Wb-bs) indices and the normalized difference vegetation index (NDVI), were obtained and correlated with geographical distribution, seasonality patterns and the two-decade evolution of fascioliasis in livestock throughout the province. …
The importance of reliable climatic data in the energy evaluation
2012
Abstract In the last few years, more and more attention has been focused on energy issues, as it is pointed out, for example, by the Directive 2002/91/EC on the Energy Performance of Buildings and Directive 2009/28/EC on the promotion of the use of energy from renewable sources. However, in order to do that, reliable tools for technicians to design systems for such topics should be provided. Nowadays, several software are available; the weak point is the availability of reliable climatic data and, above all, the ones referring to solar radiation. In this work, after a short overview of the world climatic databases, a description of three statistical methods for the elaboration of a climatic…
Comparison of methodologies for Test Reference Year (TRY) generation for Mediterranean sites
2008
The improvement of the energy efficiency of buildings calls for the availability of tools for evaluating and simulating the thermal behaviour of buildings. These simulation tools generally need a complete input data set and, in particular, information referring to the climatic conditions of the site where buildings are built-up. Among climatic issues, particularly important for the thermal energy balance is the solar radiation. However, this huge mass of data is not very useful in this form, so simple aggregation methods have been developed in order to run these simulation computer programs: the test reference year (TRY) is one of the most used methods. In this paper the comparison of two m…
