Modeling Abiotic Processes of Aniline in Water-Saturated Soils
(03/18/2000)The long-term interactions of aromatic amines with soils are important in defining the fate and transport of these compounds in the environment. Abiotic loss of aniline from the aqueous phase to the soil phase occurs with ... -
Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
(06/01/2001)Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ... -
Modeling Short-Term Soil−Water Distribution of Aromatic Amines
(1998-12-08)The applicability of a distributed parameter model for describing the distribution of aniline and α-naphthylamine between soil and aqueous phases at short contact times was assessed. Mass action equations considered in the ... -
Heterogeneous photochemical reactions of decabromodiphenyl ether
(11/03/2009)Brominated diphenyl ethers area major class of brominated flame retardants, with production of decabromodiphenyl ether (DBDPE) contributing significantly to this total. Although little is known about the mechanisms and ... -
Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus
(2014-04-24)Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different ... -
Genetic diversity and connectivity remain high in Holothuria polii (Delle Chiaje 1823) across a coastal lagoon-open sea environmental gradient
(2010-07-11)Coastal lagoons represent habitats with widely heterogeneous environmental conditions, particularly as regards salinity and temperature, which fluctuate in both space and time. These characteristics suggest that physical ... -

Spatial genetic structure in the saddled sea bream (Oblada melanura [Linnaeus, 1758]) suggests multi-scaled patterns of connectivity between protected and unprotected areas in the Western Mediterranean Sea
(2016-04-01)Marine protected areas (MPAs) and networks of MPAs are advocated worldwide for the achievement of marine conservation objectives. Although the knowledge about population connectivity is considered fundamental for the optimal ... -
Connectivity between coastal lagoons and sea: Asymmetrical effects on assemblages' and populations' structure
(2018-03-02)Connectivity among marine populations plays a fundamental role in the dynamic of metapopulations and communities. Moreover, genetic connectivity is important for the evolutionary history and adaptive capability of species ... -
Informational kiosk interactive
(08/21/2013)This paper presents the implementation of the System user interface KINFO-UTP using video game technology. We discuss the cataloging facilities building # 3 of the Technological University of Panama, which are displayed ... -
