This paper reviews methods that can be used to estimate the loss in use value associated with saltwater beach recreation in the case of an environmental accident, such as an oil spill. Particular attention is focused on methods for verifying beach attendance data and on transferring benefit estimates from other locales. The paper first reviews methods for estimating what reported attendance mig...
The aim of this study was to isolate and identify airborne fungi from locations in Babol city, Babolkenar forest and a beach on the Caspian Sea (all in North part of Iran) in spring and summer. Of 126 samples collected, the most clinically important isolated fungi were Mucor spp. (18.6%) in the forest, Alternaria spp. (13.4%) at the beach; and Cladophialophora spp. (15.8%), Mucor spp. (11.7%) a...
anopheles stephensi is one of the main vectors of malaria in the world including south of iran. three geographical populations for an. stephensi have been defined, based on egg morphology. the aim of the current study is determining the ability of different geographical populations of an. stephensi in the transmission of plasmodium berghei using anka strain of this parasite. four geographical p...
in this research work the classification of the southern coasts of the caspian sea is performed using sedimentary and morphodynamic indices. this includes field study of morphodynamic characteristics of the shore structures. field measurements include in situ samplings of sediments and actual observations of structures on site. these field activities were done along six transects in the dry coa...

This study quantified Escherichia coli (EC) and enterococci (ENT) in beach waters and dominant source materials, correlated these with ambient conditions, and determined selected EC genotypes and ENT phenotypes. Bathing-water ENT criteria were exceeded more frequently than EC criteria, providing conflicting interpretations of water quality. Dominant sources of EC and ENT were bird feces (10(8)/...
The yellow clam Mesodesma mactroides (Deshayes, 1854) is a seasonal migrant that moves in spring to the sandy upper intertidal level. In this paper we analyze the spatial distribution of density and mean shell size of the yellow clam population in Monte Hermoso beach (Argentina) in winter 1995, i.e., three months before the mass mortality occurred in November 1995. Sampling covered 32 km of bea...
© 2011 Universitat Autònoma de Barcelona Tots els drets reservats Environmental quality of Sitges beaches during the bathing season 05/2012 Environment and Preservation. Beach surface has considerably increased since 1956 by the construction of breakwaters and ports, but some beaches are still prone to erosion. An adequate management of the, nowadays fragile, underwater prairies and dune vegeta...
I summarize key aspects of the quest for physics beyond the Standard Model in flavour physics as discussed at the BEACH 2014 conference in Birmingham.
