Plastic transport in a complex confluence of the Mekong River in Cambodia

open access: yes, 2021
Field data on plastic pollution is extremely limited in Southeast Asian rivers. Here we present the first field measurements of plastic transport in the Mekong, based on a comprehensive monitoring campaign during the monsoon season in the confluence of ...

Confluences

open access: yes, 2020
In this book, Canadian scholar David Geoffrey Smith reflects on over thirty years of research and teaching in the human sciences, including education. Written between 1986 and 2018, the essays are organized around four themes: Hermeneutics and the Human Sciences; The Poststructuralist Turn; Globalization and Its Discontents; East/West Encounters and ...

Interactions between groundwater and surface water at river banks and the confluence of rivers [PDF]

open access: yes, 2004
Riparian vegetation depends on hydrological resources and has to adapt to changes in water levels and soil moisture conditions. The origin and mixing of water in the streamside corridor were studied in detail.

The impact of significant input of fine sediment on benthic fauna at tributary junctions: a case study of the Bermejo-Paraguay River confluence, Argentina [PDF]

open access: yes, 2014
This study examines the morphological features, suspended sediment inputs and hydraulic conditions within a large river in association with ecological patterns before and after a tributary confluence.

Density Effects at a Concordant Bed Natural River Confluence

open access: yesWater Resources Research, 2020
Confluences are locations of complex hydrodynamic conditions within river systems. The effects on hydrodynamics and mixing of temperature‐induced density differences between incoming flows are investigated at a small‐size, concordant bed confluence.

Morphology, flow structure, and sediment transport in the Paraná and Piquiri Rivers confluence, Brazil

open access: yesRevista Brasileira de Geomorfologia, 2023
Confluences are places of complex interaction of flow and sediments coming from different channels. Studies at large confluences have advanced the understanding of these environments on a larger scale.

Characterizing PSPACE with Shallow Non-Confluent P Systems [PDF]

open access: yes, 2018
In P systems with active membranes, the question of understanding the power of non-confluence within a polynomial time bound is still an open problem.

3D numerical simulation of the separation zone at the channel–pipe junction

open access: yesWater Science and Technology, 2023
At the confluence zone, the separation zone affects the flow, pollutant transport, and damages the bed and sidewalls of the channel. In this research, the geometric characteristics of the separation zone and the tailwater effect at the 90° channel–pipe ...

Immediate efficacy and persistent speed of kill of a novel oral formulation of afoxolaner (NexGardTM) against induced infestations with Ixodes ricinus ticks

open access: yesParasites & Vectors, 2014
Background Ticks are hematophageous arthropods that transmit a wide spectrum of pathogens to human and animals. The ability of an acaricidal product to kill ticks quickly provides an important added benefit, especially as protecting dogs from tick bites ...

Observation of implicit complexity by non confluence [PDF]

open access: yes, 2010
We propose to consider non confluence with respect to implicit complexity. We come back to some well known classes of first-order functional program, for which we have a characterization of their intentional properties, namely the class of cons-free ...
