Explicit Mapping of Acoustic Regimes For Wind Instruments [PDF]

open access: yes, 2014
This paper proposes a methodology to map the various acoustic regimes of wind instruments. The maps can be generated in a multi-dimensional space consisting of design, control parameters, and initial conditions.

Following up on a Margalevian concept: Interactions and exchanges among adjacent parcels of coastal landscapes

open access: yesScientia Marina, 2001
Some decades ago Margalef speculated that study of the exchanges across boundaries that separate different types of ecological systems would provide significant insights about properties and processes within the units that make up ecological mosaics ...

Removal of dissolved organic matter in sugar mill effluent by catalytic ozonation with activated carbon (O3/GAC)

open access: yesEngineering and Applied Science Research, 2021
This study investigated removals of dissolved organic carbon (DOC) in natural surface water mixed effluent (NW-EFF) of sugar mill factory using O3, granular activated carbon (GAC) and O3/GAC as catalytic ozonation.

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY [PDF]

open access: yes, 2008
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models.

Coagulant recovery and reuse for drinking water treatment [PDF]

open access: yes, 2016
Coagulant recovery and reuse from waterworks sludge has the potential to significantly reduce waste disposal and chemicals usage for water treatment. Drinking water regulations demand purification of recovered coagulant before they can be safely reused ...

Controls on the composition and lability of dissolved organic matter in Siberia's Kolyma River basin [PDF]

open access: yes, 2012
High-latitude northern rivers export globally significant quantities of dissolved organic carbon (DOC) to the Arctic Ocean. Climate change, and its associated impacts on hydrology and potential mobilization of ancient organic matter from permafrost, is ...

Flux and Seasonality of Dissolved Organic Matter From the Northern Dvina (Severnaya Dvina) River, Russia [PDF]

open access: yes, 2018
Pan‐Arctic riverine dissolved organic carbon (DOC) fluxes represent a major transfer of carbon from land‐to‐ocean, and past scaling estimates have been predominantly derived from the six major Arctic rivers. However, smaller watersheds are constrained to

The significance of organic carbon and nutrient export from peatland-dominated landscapes subject to disturbance, a stoichiometric perspective [PDF]

open access: yes, 2009
The terrestrial-aquatic interface is a crucial environment in which to consider the fate of exported terrestrial carbon in the aquatic system. Here the fate of dissolved organic carbon (DOC) may be controlled by nutrient availability.
