Wall base ventilation system to treat rising damp: The influence of the size of the channels

One of the major causes of pathologies in our historic buildings is the presence of moisture, particularly rising damp. Since these constructions tended to be built near water lines, to facilitate their supply, and because their walls are mainly made of high porosity materials, the presence of rising damp is constant. Although many historic buildings in Portugal have already been the targets of interventions to eliminate pathologies, the fact is that it has not been possible to do it properly. The treatment techniques available nowadays are quite diverse but all of them have low applicability to historic constructions. Research has been carried out, in this past years, at the Department of Civil Engineering of the University of Coimbra in collaboration with Department of Civil Engineering of the Faculty of Engineering of the University of Porto to try and solve this problem. An old but poorly studied technique has been investigated experimentally and numerically in the past few years: ventilation of the base of the walls. It was experimentally validated to limestone walls 20 cm thick. Numerical investigation has been carried out in order to analyze the influence of different parameters on its efficiency. In this paper we present the results of the latest investigations that have been carried out about the influence of the size of the ventilation channel on its efficiency.     

Determining treatment priorities for ecclesiastical textiles using significance and conservation assessments

The Benedictine monastic community at New Norcia, Western Australia needed an assessment of their historic textile collection as a preliminary step in gaining financial support to preserve the garments. The textiles were grouped according to functional use with sampling controlled by random number generation of the registers. The highest significance and conservation rankings were rated at 5 and the lowest in the categories was given values of one. The numbers in each category fell logarithmically as the significance values increased. The number of hours of work required to stabilise the objects increased logarithmically as the conservation ranking increased from 1 to 5. Analysis of the conservation needs indicated that nearly 84% of the collection, the sum of the level 1 and level 2 textiles can be stabilised with simple preventive conservation methods practised by trained volunteers, leaving the most significant items in the care of experienced conservators. Multiplication of the conservation and the significance values provides a treatment priority score to guide collection managers in determining which objects are treated by conservators. Data is also provided on the impact of light exposure on the deterioration of the coloured fabrics of the vestments.

聚丙烯微孔膜表面的气体等离子体改性

采用空气等离子体对聚丙烯微孔膜进行表面改性,用X射线光电子能谱,扫描电镜表征膜表面形态和微观结构的变化。考察了改性膜的水接触角、水通量以及在浸没式膜-生物反应器中的动态抗污染性能力。结果表明,改性后聚丙烯微孔膜的水接触角从100°减小到40°,膜的水通量提高,污染率下降。改性后聚丙烯微孔膜的亲水性和抗污染能力得到较大提高。     

Managing Patient-centered Communication across the Type 2 Diabetes Illness Trajectory: A Grounded Practical Theory of Interactional Sensitivity

This article uses the theoretical and methodological framework of Grounded Practical Theory (GPT) to provide a lens for analyzing and interpreting discourse as a situated form of social action in routine Type 2 diabetes visits. Drawing on a total data-set of 400 audio-recorded routine visits, we randomly selected 55 visits for qualitative analysis. In this article, we use Conversation Analysis to document communication techniques, which we in turn use as evidence to ground our claims within the GPT framework. We use two single cases of interaction to analyze communication techniques physicians use when recommending a change from oral medication to insulin. We argue treatment intensification is a key moment in health communication to reflect about patient centeredness because physicians can find themselves in an interactional dilemma: while insulin may effectively help control unstable disease, an insulin recommendation may simultaneously counter patient values and treatment preferences. Our analysis suggests that physicians use what we call interactional sensitivity to balance medical need and patient preferences when making medical decisions by tailoring their communication according to the local situation and the patient's larger illness trajectory. We propose that interactional sensitivity is a type of communication work and a quality of patient-centered communication characterized by the theoretical relationship between tailoring communication to the contingencies of the local interaction and the global illness trajectory. Overall, this article contributes to health communication scholarship by proposing a normative model for reflecting on how physicians negotiate challenging interactions with patients during routine chronic illness visits.
