LAI based trees selection for mid latitude urban developments: A microclimatic study in Cairo, Egypt [PDF]

, 2010
To study the leaf area index, LAI, based thermal performance in distinguishing trees for Cairo's urban developments, ENVI-met plants database was used as platform for a foliage modeling parameter, the leaf area density, LAD.

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

A rare but fatal outcome is hepatocellular carcinoma (HCC) progressing to the right atrial tumor thrombus and inferior vena cava

Radiology Case Reports
Hepatocellular carcinoma (HCC) frequently presents with vascular invasion; however, extension of tumor thrombus into the right atrium via the inferior vena cava (IVC) is rare and associated with a poor prognosis.

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation
