Effect of water vapour condensation on the radon content in subsurface air in a hypogeal inactive-volcanic environment in Galdar cave, Spain

Fluctuations of trace gas activity as a response to variations in weather and microclimate conditions were monitored over a year in a shallow volcanic cave (Painted Cave, Galdar, Canary Islands, Spain). 222Rn concentration was used due to its greater sensitivity to hygrothermal variations than CO2 concentration. Radon concentration in the cave increases as effective vapour condensation within the porous system of the rock surfaces inside the cave increases due to humidity levels of more than 70%. Condensed water content in pores was assessed and linked to a reduction in the direct passage of trace gases. Fluctuations in radon activity as a response to variations in weather and microclimate conditions were statistically identified by clustering entropy changes on the radon signal and parameterised to predict radon concentration anomalies. This raises important implications for other research fields, including the surveillance of shallow volcanic and seismic activity, preventive conservation of cultural heritage in indoor spaces, indoor air quality control and studies to improve understanding of the role of subterranean terrestrial ecosystems as reservoirs and/or temporary sources of trace gases.

Reuse of Spanish civil war air-raid shelters in Alicante: the R46 Balmis and R31 Seneca shelter

More than a hundred public air-raid shelters were constructed beneath Alicante during the Spanish Civil war. Their architectural uniqueness and humanitarian purpose render these shelters a tangible testament to our recent history. The Alicante Municipal Archives hold reports written by technicians who inspected the shelters in the 1940s, which were subsequently included in the Special Plan for public shelters in 1953. Half a century later, in 2003, information on the air-raid shelters was included in another Special Plan aimed at protecting Alicante’s archaeological heritage. Thanks to the work of the Municipal Heritage Conservation unit (COPHIAM) and the Special Protection Plan for Urban Archaeology (PEPA), the exact or approximate locations were identified for almost 90% of the shelters known to have existed. This paper describes interventions in two of these architectural spaces using advanced museology techniques. The first concerns air-raid shelter R46, located in the Plaza del Dr. Balmis in the city centre. This was built in 1938, and is rectangular with two entrances. The second is air-raid shelter R31, located in the Plaza Séneca.

The Portuguese National Programme for the Promotion of Healthy Eating: 2012–2015

This paper describes the first 4-year period (2012–2015) of implementation of the Portuguese National Programme for the Promotion of Healthy Eating (PNPAS). PNPAS was approved in 2012 and emerged as a preventive programme for noncommunicable diseases, aiming to improve the nutritional status of the population; it represents the first national strategy in Portugal for the promotion of healthy eating. To accomplish its mission, and taking into account its overall principles, PNPAS has five main goals: (i) to increase knowledge about the food intake of the Portuguese population and about its determinants and consequences; (ii) to modify the availability of certain foods (high in sugar, salt and fat), in schools, workplaces and public spaces; (iii) to inform and empower the population for the purchase, preparation and storage of healthy food, especially the most vulnerable groups; (iv) to identify and promote crosssectoral actions that encourage the consumption of foods of good nutritional quality in an articulate and integrated way with other sectors, namely agriculture, sport, environment, education, social security and local authorities; and (v) to improve the qualifications and conduct of the different professionals who, owing to their roles, may influence nutritional knowledge, attitudes and behaviours. The design of PNPAS followed the latest strategic lines suggested by WHO and the European Commission, proposing a crosssectoral mix of interventions to ensure physical and economic access to healthy eating by creating healthy environments and empowering individuals and communities. Several actions were implemented at different levels during the first 4-year period of implementation of PNPAS; two were especially relevant. The first concerned the empowerment of citizens regarding healthy eating, where the most important aspect was introduction of a digital strategy through development of a website and a blog dedicated to healthy eating. The second concerned the development of documents for health care and other professionals, including several guidelines in new areas, such as anthropometric measures and intervention in preobesity. Process and output indicators were defined to monitor and evaluate the programme. Among those considered as output indicators were the evaluation of childhood obesity, salt consumption and intake of breakfast by school-aged children.
