Tratamiento de emisiones a la atmósfera de acetato de etilo y tolueno mediante biofiltros de turba.
2009
En las últimas décadas, la calidad del aire y el control de la contaminación atmosférica vienen siendo líneas principales de actuación en política medioambiental a fin de evitar daños sobre la salud humana y el medio ambiente. Los compuestos orgánicos volátiles, entre los que se encuentran el acetato de etilo y el tolueno, son uno de los principales contaminantes atmosféricos de origen industrial. Las nuevas reglamentaciones asociadas a la emisión de compuestos orgánicos volátiles procedentes del uso de disolventes en determinadas instalaciones industriales hacen necesaria la búsqueda de técnicas o procedimientos para reducir, minimizar o eliminar este tipo de emisiones. En este sentido, lo…
Les activités de formation APER / Le attività di formazione APER
2014
APER Project activities included training activities set up for ten young professionals, five Sicilian and five Tunisians. The training seminars – held in November 2012 and December 2013 in Tunis and in May 2013 and March 2014 in Agrigento – were intense moments of productive debate and exchange among the participants, who were asked to be proactive. Over the second year, the topics chosen to summarise and bring into focus the APER Project’s work (conservation and protection; planned maintenance and administration; use and access; communication and museography; integrated cultural tourism) were examined in depth by five couples, each one made up of a young Tunisian and a young Sicilian who …
FULL PAPER: Earth for social housing in Palestine: an alternative for a sustainable refurbishment of building’s envelopes
2016
The suitable climates in the cities of Jericho and Gaza boosted the emergence of new attempts to revive earthen architecture on organizational and individual levels. These attempts produced a number of earthen buildings in the last few years following the crucial need to find alternative low cost material instead of natural stone, which is used in a large scale in Palestine. Similar attempts had a certain response to the social needs and economic situation there. This paper focuses on the possibility of using earth as an alternative material to refurbish the envelopes of existing housing units including two categories; firstly, refurbishing envelopes of housing units those were partially de…
End-of-life and waste management of disposable beverage cups.
2021
Different human activities have caused and currently cause catastrophic environmental phenomena, and unfortunately, a significant negative contribution to these catastrophic phenomena can be attributed to uncontrolled plastic production, use and release everywhere. On the other hand, the plastics offer numerous comforts and advantages, and for this reason, the modern life is unthinkable without plastic. Currently, numerous scientific papers and large audience advertisings, related to the production and use of polymers made by natural sources, i.e. bio-based polymers, as a valid alternative to the petroleum-based counterparts, have been published. Therefore, for production of daily disposabl…
Monitoring of the effect of solar radiation and rain on the building envelope with integrated vertical vegetation
2022
The goal of the present paper is the verification of the improvement of the performance of a building envelope with a green wall also in conditions of high irradiance (≥0.6 kW/m2) and with variable meteorological conditions (sunny, cloudy, and rainy), with a focus on intense rainfall and tempest. The object of the analysis has been the Innovation and Technology for Development Center in the University Campus of the Polytechnics of Madrid, where a modular system of integrated vertical vegetation has been installed on the skin of the South and West prospects. The study is based on the analysis of the effective thermoregulation capacity of the system in different climatic situations and has be…
Comparative analysis of the thermal insulation performance of a façade enclosure integrated by vegetation under simultaneous windy and rainy climatic…
2023
The literature offers some studies on the capacity of the greenery apparatus to decrease wind speed and regulate temperatures with the combination of the moisture retained by the plants and the air passing through them, but there is little on the maintenance of performance under particular weather conditions. The aim of this contri- bution is to verify the effectiveness of a vegetal façade in particularly windy conditions combined with rainy and/or high-irradiation events. The subject of the study is the enclosure of the Technology Innovation Centre for Development (itdUPM), on the Polytechnic University of Madrid, where a green wall prototype has been installed. For the purposes of the ana…

Ethernet FSO Communications Link Performance Study Under a Controlled Fog Environment
2012
In this letter the performance of a free space optical (FSO) communication link in the presence of fog is experimentally investigated in an indoor environment. A dedicated indoor atmospheric chamber, replicating the outdoor environment, is being used to evaluate the FSO link performance under the fog condition. Theoretical analysis supported by the experimental evaluation has been carried out for the intensity modulation/direct detection on-off keying non-return-to-zero (OOK-NRZ), OOK return-to-zero (OOK-RZ) and four pulse position modulation (4-PPM) modulation formats at the Ethernet baseline data-rate. The results shown indicate that the 4-PPM signalling scheme is the most robust to the f…
