Resource use during systematic review production varies widely: a scoping review Nussbaumer Streit, B.; Martínez, P.; EVBRES COST Action Objective: We aimed to map the resource use during systematic review (SR) production and reasons why steps of the SR production are resource intensive to discover where the largest gain in improving efficiency might be possible. Study design and setting: We conducted a scoping review. An information specialist searched multiple databases (e.g., Ovid MEDLINE, Scopus) and implemented citation-based and grey literature searching. We employed dual and independent screenings of records at the title/abstract and full-text levels and data extraction. Results: We included 34 studies. Thirty-two reported on the resource use—mostly time; four described reasons why steps of the review process are resource intensive. Study selection, data extraction, and critical appraisal seem to be very resource intensive, while protocol development, literature search, or study retrieval take less time. Project management and administration required a large proportion of SR production time. Lack of experience, domain knowledge, use of collaborative and SR-tailored software, and good communication and management can be reasons why SR steps are resource intensive. Conclusion: Resource use during SR production varies widely. Areas with the largest resource use are administration and project management, study selection, data extraction, and critical appraisal of studies.

Influence of several metabolites excreted by microorganisms on building stone deterioration Bailón Moreno, Rafael; Torres-Agudo, Víctor Manuel; Bolívar-Feriche, Mónica; Bolívar Galiano, Fernando Carlos; Abad Ruiz, Clara One of the most important weathering factors of building stone, besides the meteorological phenomena (rain, snow, drought, hail…) is the biodeterioration produced by micro-organisms. In situations of water stress or extreme temperatures, microorganisms respond with the excretion of several metabolites that can affect stone. The effect of some metabolites (citric acid, ascorbic acid, oxalic acid, glucose and glycerol) has been evaluated on two types of stone with dissimilar porosity, limestone and Macael marble. The samples have been subjected to several cycles of exposure to metabolites, followed by freezing and desiccation as well as other cycles without exposure. The deterioration of the stones has been quantitatively evaluated by physical properties (bulk density, porosity, absorption and capillary water absorption). This study has concluded that deterioration depends on the nature of the stone, the presence or absence of metabolite and its chemical nature. The control of microorganisms present on building stone is essential for its conservation.

Chromatic alterations by microalgae at National Mall fountains in Washington D. C. (USA) Bolívar Galiano, Fernando Carlos; Yebra Rodríguez, Ana María; Romero-Noguera, Julio; Sánchez Castillo, Pedro Miguel The National Mall is the great promenade that connects the most important buildings of the capital of the United States: the capitol with the George Washington and Abraham Lincoln Memorials touring the Castle and the main Smithsonian museums and the National Gallery of Art. The fountains present inside and outside these museums suffer alterations of color and texture due to colonization of algal populations on the surface of their constituent materials. We have studied 9 fountain belonging to the National Gallery of Art, the Smithsonian National Museum of African American History and Culture, the Smithsonian Museum of Contemporary Art (Hirshhorn), the Smithsonian Arts and Industries Building, the Smithsonian Institution Building (the Castle), the Smithsonian National Museum of American History and the Smithsonian National Museum of the American Indian. In this work carried out by the national Project VIRARTE (UGR-MEC) at the Smithsonian Museum Conservation Institute (MCI-SI), the relationship between the diversity of the algal groups and the material composition and typology of the fountains is studied. We have studied the presence of different species of green microalgae, blue-green microalgae and diatoms that form pustules, films, mats and mineral crusts on fountains constructed with granite, limestone and various metals, and even upon sealant resins that are used to repair water leaks. The ultimate goal of this work in the control of these formations to avoid the aesthetic, functional and material damage that these photosynthetic organisms produce in the architectural heritage associated with water.

Changes in the Alhambra Palaces algal biodeterioration after 25 years Bolívar Galiano, Fernando Carlos; Abad Ruiz, Clara; Hidalgo-Hernández, Emilio; Bailón Moreno, Rafael; Torres-Agudo, Víctor Manuel; Bolívar-Feriche, Mónica; Sánchez Castillo, Pedro Miguel The architectural complex of the Alhambra in Granada is an important part of our cultural heritage, both for its historical and artistic relevance. Selected as UNESCO World Heritage Site in 1984, it is currently one of the most visited monuments in Europe. In order to preserve it, constant conservation and restoration activities are needed. An important deterioration agent that affects cultural heritage is microalgae, which are capable of colonizing and modifying stone, especially those sites with high humidity or in which water is present, like the numerous fountains, ponds and channels in the Alhambra. Microalgae form biofilms and mats that cause aesthetic alterations on stone, as well as harmful chemical and physical changes like, for instance, mineral crust formation. In the present paper, we analyze the microalgal colonization and the state of conservation of the most relevant fountains in the Nasrid Palaces of the Alhambra, and we compare it with the state of conservation and colonization they presented 25 years ago. Samplings have been carried out to identify the different species present on the fountains and to assess any modification on algal communities after this period of time, during which fountains have been subjected to different treatments and restoration processes. Presence of microalgae on the fountains and the characteristics of their communities after 25 years can serve as an indicator of the utility of the treatments employed for conservation. Despite some fountains have experienced an improvement regarding colonization in relation to the past, there are no significant changes regarding the type of the most persistent and mineralizing microalgae. It should be noted that the problem of algal colonization has not disappeared, and it would be very interesting to address it with an eye to the future.

I Congreso Nacional Multidisciplinar de Jóvenes Investigadores: libro de actas Bailón Moreno, Rafael El I Congreso Nacional Multidisciplinar de Jóvenes Investigadores ha reunido entre los días 19, 20 y 21 de abril de 2014 jóvenes investigadores de diferentes especialidades en todo el abanico del conocimiento humano (ciencias sociales y humanas, ciencias experimentales, ciencias biomédicas, etc.) , de diferentes universidades Españolas e incluso de diferentes nacionalidades para compartir experiencias en su quehacer científico y mostrar los alcances investigadores obtenidos. Se han presentado un total de 75 comunicaciones (32 presentaciones orales extensas y 43 e-posters con presentación corta) y 5 conferencias invitadas de investigadores seniors con exposiciones de espíritu docente sobre los distintos aspectos de la investigación científica. Se han realizado 12 sesiones para cubrir tanto las conferencias invitadas, como las presentaciones extensas y las presentaciones cortas de los posters.
