Research ArticleOpen accessIn the abstractA Passive Opportunity for Improving Air Quality in the Schools Environment: A Real-World Scale TestingPierpaoli Mattia, Fava GabrieleCan passive technology effectively enhance the indoor air quality? To improve classroom indoor air quality, an increase in ventilation and/or air purifiers are often suggested. In this study, a short-term intervention was implemented and investigated to evaluate the effects of a passive adsorbent surface on the pollutant deposition velocity and to improve the overall classroom air quality. We found that … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 3 Jun 2016 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Dynamic Thermal Behavior of Building Envelope in Summer Conditions By Means of in-Field Continuous MonitoringAnna Laura Pisello, Gloria Pignatta, Cristina Piselli et al.The effect of dynamic properties of building opaque envelope in summer conditions is investigated by means of an extensive continuous monitoring of a dedicated experimental field. Two test-buildings, a weather station and two microclimate stations positioned in each test-building represent the experimental field. The prototype buildings have been specifically designed to present the same stationary envelope properties, but different construction … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 25 Apr 2016 · 8,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Efficiency Investigation on Heat Recovery System Used in a Solar-Powered Desalination ProcessAouatef Rachdi, Louy Qoaider, Mahmoud Ben-Amara, AmenAllah GuizaniThe aim of this work is to experimentally study, the effect of the heat recovery on water production in a solar desalination process that is working with multiple stage humidification technique. The water production, the temperature and the humidity were tested for such a pilot plant, which operates without and with a heat recovery system. The humidifier efficiency increases with … …Energy Research Journal, Vol. 3, Issue 2 · 11 Mar 2013 · 7,268 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrying Characteristics of the Borneo Canarium odontophyllum (Dabai) FruitDayang Fredalina Basri, Ahmad Fudholi, Mohd Hafidz RuslanThe quality and shelf-life of an underutilized fruits are compromised by the conventional method of drying. We therefore proposed using hot-air chamber to develop the drying curves of Canarium odontophyllum (dabai) fruit. Present study provides evidence of the best mathematical model to demonstrate the drying characteristics of this indigenous fruit and thus, may generate or add to the existing database. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Sep 2012 · 8,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntra Urban Air Temperature Distributions in Historic Urban CenterElmira Jamei, Dilshan Remaz OssenThe study investigates the urban heat island effect in Malaysian historic town Malacca through seven mobile traverses, as carried out on 10 December 2011. It aims to identify the intra-urban air temperature differences between heritage core zone, new development area and outskirts of the city. Air temperature variations were also analyzed across three different zones; namely the outskirts, the heritage … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 17 Aug 2012 · 8,753 accessesView PDFCite
