2010/1/18
Short term changes in zooplankton community were investigated at a fixed station in offshore waters of the Ligurian Sea (DYNAPROC 2 cruise, September–October 2004). Mesozooplankton were sampled with v...
Institutional Care for the Mentally Defective, 1914–1948：Diversity as a Response to Individual Needs and an Indication of Lack of Policy Coherence
Institutional Care Mentally Defective Individual Needs
2008/11/27
In recent years mental deficiency policy and the wider issue of the history of people with learning difficulties have attracted much attention. Important publications by Mathew Thomson, Anne Digby, Ma...
This paper presents a systematic way to examine the origin of variety in falling snow. First, we define shape diversity as the logarithm of the number of possible distinguishable crystal forms for a g...
