Seasonal Pattern and Sources of Particulate Carbon in Kananaskis and Calgary, Alberta
Sources, seasonal pattern of elemental carbon(EC), organic carbon(OC), and total carbon from dry deposition and precipitation in Kananaskis and Calgary were assessed using thermo-optical methods. Vehicle exhaust was inferred to be dominant source of carbon throughout the year with an identical …

Development Of A Unified Approach (An Index) To Study The Particulate, Carbon Monoxide Emissions And The Combustion Efficiency Using Field And Laboratory Investigations
About one-third of the world’s population uses biomass and other renewable sources of fuel for cooking and other heating purposes. The Biomass is not burnt efficiently which results in the release of pollutants which are the products of incomplete combustion. Previously, studies have been done to …

PARTICLE-WATER INTERACTIONS OF HYDROPHOBIC ORGANIC MICROPOLLUTANTS IN MARINE SYSTEMS
… estuarine variables (organic matter, suspended particulate matter [SPM], particle type and salinity) on HOM behaviour was investigated by employing samples from estuaries with different geochemical signatures (Chupa, Russia, and the Dart, Plym, Beaulieu and Carnon, U K ) . A laboratory-based …

Analytical and experimental analysis of fireplace performance
A preliminary fireplace design to reduce particulate, carbon monoxide, and unburned hydrocarbon emissions has been fabricated and tested. Using a damper and glass pane, the design solves the problem of uncontrolled air entering the firebox. The pane reduces the inlet area and directs the flow of …

Bacterioplankton dynamics in the Southern Benguela upwelling region
The role of heterotrophic bacteria in the carbon and nitrogen flux of the pelagic food web was investigated during laboratory and field-based studies of the temporal development of the planktonic community after upwelling. Bacterial community structure, activity and production were closely coupled …

The chemistry, biology, and vertical flux of oceanic particulate matter
Particulate matter samples, split into <l μm, 1-53 μm, and >53 μm size fractions have been obtained using a Large Volume in situ Filtration System (LVFS) during the SOUTHLANT expedition, R/V CHAIN 115. Profiles to 400 m are reported for LVFS Stns. 2 and 4-8. Stns. 4, 5, and 8 (S. E. Atlantic, …

Assimilatory sulfur metabolism in marine microorganisms
… Biomass parameters (cell counts, bulk protein, particulate carbon and nitrogen), total uptake of radioactive sulfate, and the distribution of sulfur in major biochemical components (low molecular weight [L.M.W.], alcohol soluble protein, lipid, hot TCA soluble material, and residue protein) were …

Evaluation of three carbon sources for the biological treatment of acid mine drainage through process modelling
… of cost effective and efficient sources of carbon and electron donors. This thesis aims to evaluate three different substrates as sources of carbon and electron donor capacity (ethanol, molasses and primary sewage sludge) in terms of their availability and their impact on both final water …

Particulate fluxes in the subtropical convergence region and other marine environments of New Zealand
… and physical processes affecting modem particulate sedimentation in the vicinity of the Subtropical Convergence Zone, and the magnitude and composition of particulate fluxes within the Chatham Rise-Subtropical Convergence region. An overall conservative strategy was adopted for the …
