The interferon-gamma (IFN-γ) assay is an effective tool for the diagnosis of tuberculosis (Tb) in goats. The objectives of this study were to evaluate factors that might affect assay performance: (1) the phenol concentration of the purified protein derivative (PPD, tuberculin) used; (2) dialysis of PPD; and (3) delaying antigenic stimulation of blood samples for 8, 16 and 24. h after collection. The assay was performed in duplicate with two cut-off points. Dialysis of PPD reduced test sensitivity, whereas the concentration of phenol did not significantly affect test outcome. Delaying antigenic stimulation of samples >8. h resulted in a reduction in test sensitivity, compromising the capacity of the assay to detect infected animals. Performing the assay in duplicate was unnecessary, which has implications for reducing assay costs. These findings will facilitate the effective application of the IFN-γ assay as an ancillary test in Tb eradication programmes in goats. © 2010 Elsevier Ltd. Source

Dam Maintenance and Rehabilitation II - Proceedings of the 2nd International Congress on Dam Maintenance and Rehabilitation | Year: 2011

Alarcón reservoir, with a capacity exceeding one cubic kilometer, is located on the river Júcar and represents the main regulatory infrastructure resources of the river basin. In 2005, the adaptation project of the Alarcón dam spillway was made. This project includes the modernization of all hydraulic components of the dam. The planned measures in the Project must be implemented under the premise of a minimal condition for normal operation thereof and without prejudice to the highest standards of safety. Stands out the redesign of the spillway. Structurally, the contact between the existing concrete and the new has been analyzed, so it has been necessary to design a drainage system that limits the generation of uplift on the surface of contact and the bolting of union in-between both. The works are currently underway. © 2011 Taylor & Francis Group, London. Source

Proceedings of the 3rd International Forum on Risk Analysis, Dam Safety Dam Security and Critical Infrastructure Management, 3IWRDD-FORUM | Year: 2012

The General Directorate for Water of the Ministry for Environment and Rural and Marine Affairs has under its assigned tasks the duty of analysing all Safety Inspection on dams. This has been done, in the case of the basin of the Guadalquivir river, by means of a collaboration with the engineering consultant IBERHIDRA. Once the documents of the Safety Inspections have been analysed and a technical visit of each dam has been undertaken, the tools of risk analysis have been applied. The profound knowledge on the dam gained in the process of analysing its Safety Inspection has helped to be able to be able to apply risk analysis tools without too great an effort. Also, as the same group of professionals has checked through all the dams of the basin, a certain homogeneity in the criteria has been achieved, this way making it possible to use the results to compare the dams in between them. © 2012 Taylor & Francis Group.

Mycobacterium caprae is a pathogen that can infect animals and humans. To better understand the epidemiology of M. caprae, we spoligotyped 791 animal isolates. Results suggest infection is widespread in Spain, affecting 6 domestic and wild animal species. The epidemiology is driven by infections in caprids, although the organism has emerged in cattle.

Zinnia and tagete flowers present vivid and uniform colors, ideal characteristics for its use in urban landscapes, including applications in vertical gardens coverage and green roofs. In these systems, it is necessary to optimize the use of water and irrigation management in order to ensure the survival of vegetation cover. With the aim of selecting plants suitable for use in vertical gardens and green roofs, we evaluated the effects of irrigation water salinity using a recirculating hydroponic nutrient solution. The ion content in the tissues of plants and their effects on the ornamental characteristics were characterized. 6, 30 and 50 mM NaCl was added to nutrient solutions to obtain final electrical conductivities of 2.0, 4.5 and 6.5 dS m−1, respectively. The increases in salinity affected plant growth, causing a decrease in biomass, height and major and minor diameters. However, salinity did not affect zinnia flower production and did not produce toxicity symptoms in tagete leaves despite the significant accumulation of Na+ and Cl− in these tissues. These results highlight the salinity tolerance of tagete and zinnia, and their possible use in urban landscape irrigated with poor quality water. © 2014 Asociacion Interprofesional para el Desarrollo Agrario.
