The world’s forests store an estimated 861 billion tonnes of carbon—equivalent to approximately 100 years worth of anthropogenic emissions, at current rates—and with good husbandry could potentially store up to 226 billion tonnes more. Clearly, preserving and repairing forests is a vital element of mitigating climate breakdown.

Carbon footprint of next generation fixed networks
Intelec 2010, 2010For the first time a full/streamlined life cycle assessment (LCA) case study was performed to estimate the carbon footprint of three types of FTTx networks deployed in Italy. The functional unit is “broadband network in an Italian urban dense area for use by 10,000 homes during one year” The worst case results show that FTTB, FTTCab, and FTTH all emit ...

Fixed high-stability carbon resistors
Journal of the Institution of Electrical Engineers - Part IIIA: Radiocommunication, 1947High-stability fixed resistors of a wide range of values were developed during the war for special applications.Smooth ceramic rods were coated with carbon films, by pyrolitic decomposition of methane in a continuous furnace. The resistance value so obtained was increased by cutting a spiral track on the coated surface of the rod.

Antioxidants from carbon dioxide fixing Chlorella sorokiniana
Journal of Applied Phycology, 2000Chlorella sorokiniana H-84, which has toleranceto high temperatures and high concentrations ofCO2, has been isolated from a hot spring inJapan. Large-scale culturing of C. sorokinianawas carried out in air containing 10% CO2.Analysis of the biomass shows that protein, carbohydrate and lipids comprised 68.5, 11.9 and10.0% of dry matter, respectively ...

Ammonia adsorption in a fixed bed of activated carbon
Bioresource Technology, 2007The rise in atmospheric pollution caused by gases such as ammonia has led many researchers to conduct studies aimed at decreasing or treating the emissions of such polluting gases. The present work attempted to study the adsorption of ammonia in the fixed bed of activated carbon as a means to treat its emissions.

Adsorption of p-nitrophenol on activated carbon fixed-bed
Water Research, 2006Carbon fixed-beds are usually used to remove organic contaminants. Adsorption in a carbon filter is a dynamic, non-steady process which is not yet completely understood. The objective of this paper is to establish a methodology to simplify the study of this process based on the wave theory, rapid small-scale column test and experimental design/surface ...

Excretion of photosynthetically fixed organic carbon by metalimnetic phytoplankton
Microbial Ecology, 1985The effects of light intensity, oxygen concentration, and pH on the rates of photosynthesis and net excretion by metalimnetic phytoplankton populations of Little Crooked Lake, Indiana, were studied. Photosynthetic rates increased from 1.42 to 3.14 mg C·mg(-1) chlorophylla·hour(-1) within a range of light intensities from 65 to 150μE·m(-2)·sec(-1 ...
