Landslide is a dangerous phenomenon according to geomechanical viewpoint, being able to produce huge damages because of sliding and can involve structures and infrastructures. However, mechanical aspects are generally recognized since they provoke the above consequences. Environmental aspects related to breaking in the land must be considered. Land breaks or cracks allow outside water, not only from rain, to reach surface and subterranean aquifers. Contacts between external waters, maybe containing diverse pollutants, and aquifers, would be considered as source of contamination. The paper...

Particulate matters and ozone are often neglected as pollutant elements when people deal with widespread pollution. Particulate matters PM 10 , PM 2.5 , are produced by human activities namely industries and car traffic but also by natural activities like blowing wind from desert, volcanoes, etc... Ozone, instead, has a double consideration: it is beneficial as ozone layer in the upper atmosphere because it serves as natural filter to reduce UV rays that arrive at earth surface. But at ground level, high amounts of ozone, in terms of concentration are harmful for human health. The research...

SCADA systems have been used during the last years in order to control and supervise industrial processes within a long distance, thus considerably reducing the loss of information, apart from offering a higher speed and security of data. Nowadays, due to the fast development of Internet of Things, of wireless communication and of electronics, a better efficiency in industrial processes has been established, this being possible due to the use of specialized protocols and software, which, have been able to expand to house and building applications because of the easiness of their programming...

Biochar obtained from thermochemical conversion of biomass reduces greenhouse gas emissions, improves the physicochemical and microbial properties of soil and absorbs pernicious substances. In addition, applying biochar in agriculture helps to significantly reduce the water consumption for irrigation, an important issue for Aguascalientes, a semidesertic site in the center of Mexico. Therefore, declaring the benefits by applying biochar to soils and estimating the minimum biomass and biochar potential of Aguascalientes is the key issue of this paper.

The present paper reports the preliminary results of a study carried out to characterize the thermal response of apple surface wax layer. The experimentation has been performed on three different cultivars of apple (Golden delicious, Fuji and Red delicious). The present study is part of a research project which final aim is to reproduce artificially bio-wax films in order to cover and protect fruits during their life cycle from the tree to the table. Wax is a natural substance which covers the surface of some species of fruits such as the apples. This wax layer protects the fruit against...

This paper presents a general methodology for processing bioclimatic data in the temporal domain. Two different methods are used to assess the presence of temporal trends in the time-series of bioclimatic indices at each measurement station. A preliminary stage checks for the statistical homogeneity in the data set and for the presence of serial autocorrelation in the data, applying the proper methods to remove these effects. The methodology has been applied to a case study in Apulia, Italy, using the popular De Martonne index as a bioclimatic indicator.

The electrical output of a photovoltaic system is often related to the plane-of-array global irradiance and the cell operating temperature. However, the spectral distribution of the irradiance also influences the system electrical behavior, through its coupling with the spectral response of the photovoltaic material employed. Since early in the 1990s, many authors have evaluated the spectral performance of different types of semiconductors under real operating conditions worldwide. For this purpose, different methods and indexes have been proposed. In this paper, the fundamentals of the...

This paper presents a general methodology for processing bioclimatic data in the spatial domain whose main goal is to derive indications related to the moisture/dryness level of a region and provide water management authorities with information about its irrigation requirements. The methodology uses point-scale measurements of weather related data to perform a detailed analysis of the spatial behavior of the corresponding bioclimatic indicators at the continuous regional scale. The proposed methodology, although more demanding in terms of computation resources, gives more accurate results...

This work is related to the structural and dynamic analysis of vibrations tested in a model of building-like structure which is armed by a three-story building with a Tuned Mass Damper vibration absorber. The structure it is connected to an electromagnetic shaker, which excited the support of the structure, provides forces with a wide range of excitation frequencies, including some resonance frequencies of the structure. The vibration absorber is a typical passive absorber known as Tuned Mass Damper (TMD), located over the third story building to reduce the vibrations. The overall mechanical...

In this paper, the authors aimed to summarize the results of an analytical study that evaluated the vibration analysis control of an on-shore wind turbine subjected to earthquake forces. The on-shore wind turbine (model G80 - 2.0 MW, manufactured by Gamesa Company) was modeled mathematically as a simplified mechanical system. The primary purpose of this work is related to the analysis of the lateral displacement of the wind turbine and to undertake a mechanical vibration study to reduce the effects of such displacements induced by earthquake ground motions across the entire system. Simulated...
