Klossiella is a genus of apicomplexan coccidian parasites with a global distribution, whose members typically infect the renal tissue of a wide variety of vertebrate hosts with a high level of host specificity. The presence of this parasite has been previously associated with kidney inflammatory processes. To our knowledge, this is the first report on the prevalence of Klossiella muris in the house mouse (Mus musculus) in Portugal (São Miguel Island – Azores). The prevalence of K. muris was determined through histopathological examination of renal tissue collected during necropsy of 130 mice captured between the years of 2011–2019. K. muris was diagnosed in 45.38% (CI95: 40.9–85.4) of the examined mice. Infection with this parasite was associated with mild to severe kidney inflammation, assessed by the presence of inflammatory processes in the renal cortex and medulla.

Coastal waters are an integral part of the natural environment. Careful planning and management is needed to protect and conserve them, and to ensure that the water supply is useful for a variety of uses. Submarine outfalls for effluent disposal are used to ensure that the water quality is maintained and that the environmental values and water uses are protected. Decision on treatment and disposal is based on objectives set by national and international legislation and on coastal and maritime uses identification. An operational forecast methodology is proposed for the management of submarine outfalls providing information to deal with the marine environment problems and to satisfy needs at different levels for coastal communities. From a management perspective the forecast methodology will support decision making by predicting where a discharged plume is likely to be transported over a few days from its last known location. Short-term forecasts of maritime climate and hydrological conditions along with foreseen effluent characteristics (depending on seasons and population equivalent) of the studied region are used for an accurate estimation of the effluent plume advection and diffusion processes near the coastline. The operational forecast methodology, continuously evaluating the plume behavior and its relation with the protection perimeter (identified through a coastal usage map), allows the implementation of a precautionary and adjustable management of the submarine outfall. Corrective measures (e.g. increase dilution, increase the number of outlets, increase outflow speed) may avoid possible operational disruptions and minimize potential water quality impacts. To illustrate the application of the procedure, a submarine outfall case study located in the Portuguese coast is analysed. ; 6 ; 3 ; 12p ; DHA/NPE ; MWWD & IEMES 2012 - MONTENEGRO

The paper presents a risk assessment methodology for operational limit states of submarine outfall projects that considers: the intrinsic nature of the structure, the environmental legislative framework, the climate agents acting on the coastline and prediction of the plume long-term behavior near the coastline, together with the empirical orthogonal functions analysis. The probability of operational failure or stoppage is assessed enabling decision on project design alternatives. ; 7 ; 3 ; 11p ; DHA/NPE ; 2013 ; 4 a 7 de Junho
