X-ray based tree ring analyses [PDF]
, 2004 In this thesis, two x-ray based dendro-analyses (batch-wise microdensitometry and energy dispersive x-ray fluorescence (EDXRF)) and the conditions under which these methods could be used on the two typical boreal conifers Norway spruce (Picea abies (L ...

Detecting a rotation in the epsilon Eridani debris disc
, 2006 The evidence for a rotation of the epsilon Eridani debris disc is examined. Data at 850 micron wavelength were previously obtained using the Submillimetre Common User Bolometer Array (SCUBA) over periods in 1997-1998 and 2000-2002.

Tree ring study of Cordia alliodora (Ruiz & Pav.) in Colombia
Colombia Forestal, 2016 Cordia alliodora has a high ecological and economical value in the dry forest of Colombia. We documented the relationship between tree growth and climate variables (total annual precipitation, mean annual temperature) and the southern oscillation index ...

Handling Network Partitions and Mergers in Structured Overlay Networks [PDF]
, 2007 Structured overlay networks form a major class of peer-to-peer systems, which are touted for their abilities to scale, tolerate failures, and self-manage. Any long-lived Internet-scale distributed system is destined to face network partitions. Although

Using longitudinal survival probabilities to test field vigour estimates in sugar maple (Acer saccharum Marsh.) [PDF]
, 2008 Tree mortality is a major force driving forest dynamics. To foresters, however, tree mortality is often considered a loss in productivity. To reduce tree mortality, silvicultural systems, such as selection cuts, aim at removing trees that are more likely
