A building needs to be designed for the whole period of its useful life according requirements. However, future climate predictions involve some uncertainty. Thus, several sustainable strategies adaptation need incorporated after initial design. In this sense, tunnel ventilation in broiler houses provides high air velocity values (2–3 m·s−1) at animal level diminish their thermal stress and associated mortality. This system was experimentally into a Mediterranean climate. The aim resolve...

Preventive conservation represents a working method and combination of techniques which helps in determining controlling the deterioration process cultural heritage order to take necessary actions before it occurs. It is acknowledged as important, both terms preserving also reducing cost future measures. Therefore, long-term monitoring physical parameters influencing necessary. In context Smart Cities, interest perform comparative studies load information into cloud that will be useful for...

Monitoring temperature and relative humidity of the environment to which artefacts are exposed is fundamental in preventive conservation studies. The common approach setting measuring instruments choice a high sampling rate detect short fluctuations increase accuracy statistical analysis. However, recent cultural heritage standards evaluation variability based on moving average therefore massive acquisition data slowly-changing indoor environments could end up being redundant. In this...

<p>Reproductive performance is greatly affected by environmental factors such as temperature. Heat stress (HS) during pregnancy and lactation can influence not only foetal growth but also postnatal development of kits. The aim this study was to test the effect HS gestation on till Spanish commercial liveweight. To investigate this, 32 primiparous non lactating rabbit does were exposed 1 2 treatments: high temperature (between 25 36°C, group; n=16) or thermoneutral conditions 14 20°C,...

This paper deals with the development of a multidisciplinary study on current state conservation Ariadne's house (Pompeii, Italy), domus great archaeological value.The aim this is to undertake preventive actions required and increase knowledge about its generate discussions points view for future restoration.Environmental studies, electromagnetic radiation measurements, materials photographical were carried out.Those studies revealed that rooftops covering analyzed rooms resulting in adverse...

The rearing of poultry for meat production (broilers) is an agricultural food industry with high relevance to the economy and development some countries. Periodic episodes extreme climatic conditions during summer season can cause mortality among birds, resulting in economic losses. In this context, ventilation systems within houses play a critical role ensure appropriate indoor conditions. objective study was develop multisensor system evaluate design broiler houses. A measurement equipped...

Preventive conservation requires monitoring and control of the parameters involved in deterioration process, mainly temperature relative humidity. It is important to characterise an archaeological site prior carrying out comparative studies future for preventive conservation, either by regular verify whether conditions are constant, or occasional ones when boundary altered. There numerous covered sites, but few works that give special attention type cover installed. In particular, there no...

The famous Renaissance frescoes in Valencia’s Cathedral (Spain) have been kept under confined temperature and relative humidity (RH) conditions for about 300 years, until the removal of baroque vault covering them 2006. In interest longer-term preservation order to maintain these good condition, a unique monitoring system was implemented record both air RH. Sensors were installed at different points apse during restoration process. present study proposes statistical methodology analyzing...

The mudéjar church of Santa María (Ateca) is valuable for its architecture and the altarpiece contained inside. Ateca a village with continental climate characterized by cold winters hot summers. In this paper we are interested in analysing effect temperature relative humidity (RH) changes produced heating system on altarpiece. Therefore, monitoring 15 sensors was installed recording frequency data point per minute. main contribution quantitative study thermo-hygrometric parameters using...

One of the major constraint factors for rabbit production consists environmental conditions and especially high temperatures that negatively affect reproduction growth performance. For this reason, several studies have addressed effects heat stress possible solutions to alleviate its impact on This article describes design operating features a large temperature chamber (13×4.7×3.1 m) configured house 42 rabbits. The probes consisted sensor model DS2438 humidity HIH-5031. system was...

Abstract Background A microclimate monitoring study was conducted in 2008 aimed at assessing the conservation risks affecting valuable wall paintings decorating Ariadne’s House (Pompeii, Italy). It found that thermohygrometric conditions were very unfavorable for of frescoes. As a result, it decided to implement corrective measures, and transparent polycarbonate sheets covering three rooms (one them delimited by four walls others composed walls) replaced opaque roofs. In order examine...
