The current context and changes in the communicational paradigm in the last ten years lead to think we are experiencing a moment of transition that entails the end of mass media, like different studies have concluded. Among them, the most vulnerable product is the printed newspaper, which disappearance generates few doubts. However, immersed in this moment of change, we cannot yet evaluate what means to lose a journalistic model that has prevailed for over two centuries and a half as informational reference. From this perspective, the province of Cuenca, in Castile-La Mancha, one of the two in Spain which today no longer has a printed newspaper, offers us a unique scenario to approach what kind of medium positions as leader in its place. Using a mixed methodology, based on the review of documentary sources and contents analysis, we analyse a case study that aims to collect tendencies regarding proximity media. In this case, the switching from one platform to another has devaluated very relevant journalistic genres, such as the photo news or the editorial, but also some core practices in the journalism, like the editing task on the material that arriving to the editorial offices.

The aim of this study was to assess the quality of paper and cardboard coated with different emulsions as food contact materials. The paper and cardboard were covered (impregnated) with a single layer of three different emulsions produced using paraffin and waxes, varying in content of dry matter, pH and emulsifiers. The organoleptic properties, overall and specific migration expressed as cadmium and lead content, were evaluated. Moreover, the water and oil contact angle and samples’ microstructure were analyzed in order to determine the resistance of materials to moisture and grease penetration. The analysis of scanning electron microscope (SEM) images indicated that some of the examined emulsions penetrated the material, and others created a layer of coating. Impregnation of paper and board caused a change in smell, but did not influence the taste of food used to test the impact on sensorial properties. It is worth emphasizing that overall migration limit was not exceeded in the case of all investigated samples. The samples impregnated with emulsions were characterized as having better water (including water vapour) and oil resistance in comparison with the non-coated ones. [ABSTRACT FROM AUTHOR]

The effect of paper structure on blood typing visualization was quantified and analyzed to engineer low-cost diagnostics. Commercial and experimental papers varying in fibre composition, basis weight, density and porosity were investigated for their ability to separate agglutinated (blood interacted with specific antibodies) from non-agglutinated (blood interacted with non-specific antibodies) red blood cells (RBCs). Antibodies solutions and blood samples were sequentially absorbed on paper, allowed to interact, eluded with a saline solution, and the intensity of the remaining blood spot was quantified by image analysis. The efficiency and clarity of RBC separation was quantified with the relative intensity (R.I.) index defined as the intensity ratio of the non-specific test over the specific system; the lower the R.I., the better is the separation between a positive from a negative test. Thick and dense papers are improper for blood typing as they retain indiscriminately both agglutinated and non-agglutinated RBCs. Thin and porous papers provided the best performance. The R.I. index (the lower the better) increased fairly linearly with paper density and thickness but inversely proportionally with paper pore size. The type of fibres played a minor role. The paper structure is critical in the design of blood typing assay. However, it is only one element of the diagnostic system to engineer with the interactions RBC-antibody-paper.

Abstract: Sustainable recyclable paper and composite materials can be ideal choices for the construction of temporary structures for both exhibition spaces or for rapid-recovery shelters in emergency operations. The unique engineering and sustainable features of these structures need to be considered as an integral part of the design process from the conceptual phase. Engineering studies to analyze these structures should be as important as the overall artistic and architectural vision. This paper examines the use of environmentally creep-formed paper tubes for the design, construction, and exhibition of, “Portals to an Architecture”, a large temporary outdoor sculpture.
