Fires at Composting Facilities: Causes and Conditions

by BioCycle Magazine  (Jan. 1, 2000)

The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting ...

Landfill site improvement condition for PPC permit

by ESI Ltd - Environment Specialists  (Oct. 8, 2011)

The installation is a landfill site licensed for the disposal of inert waste. It lies in a potentially sensitive location on the flood plain of the River Great Ouse, near Milton Keynes and it is therefore important to the client to ensure good environmental monitoring is undertaken. The site is divided into two sections, (the north western area ...

Diatoms for assessing the ecological condition of inland freshwater bodies

by Inderscience Publishers  (Apr. 19, 2010)

The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, ...

Variability of PM10 concentrations dependent on meteorological conditions

by Inderscience Publishers  (Dec. 9, 2008)

The influence of atmospheric exchange conditions on near-surface PM10 concentrations is analysed for four cities in the South-West of Germany in the period from 2001 to 2005.

Integrated condition assessment for Navy system of systems

by Inderscience Publishers  (Mar. 18, 2013)

Although the US Navy has made great strides in integrating technology to monitor and assess the condition of sub–systems, little is understood about how to fuse this data in order to construct a higher level awareness of the ship's overall readiness or current state. Drawing upon systems theory and systems–based approaches, we identify principles ...

Effect of different water conditions on dissolution of nanosilver
