Variation in the diversity of ichthyoplankton was analyzed from samples collected during threeyear cycle in Boka Kotorska Bay. Samples were collected using Calvet (modified PairOVET) plankton net at 18 stations, from July 2006 through January 2009. Families with most numerous species were Engraulidae, Sparidae and Labridae. Investigation shows dominance of anchovy (Engraulis encrasicolus), Medi...

Information of vegetation structure and composition terrestrial flora biodiversity can be measured by analysis method. The method requires sampling plots as a measurement plot capable to describe species in forest stand. distribution diversity, especially plants, is relatively dependent on the type plant with condition area it occupies. Therefore, an efficient representative needed for ecosyste...

In 1942, Henry Sigerist questioned the idea that "the German way in public health was to enforce health through the police while the English way consisted in acting through education and persuasion".2 Contrasts of this kind have, however, remained commonplace throughout the twentieth century.3 In the 1950s, George Rosen sought to reframe the history of public health in order to understand how i...

BACKGROUND Narrative medical reports do not use standardized terminology and often bring insufficient information for statistical processing and medical decision making. Objectives of the paper are to propose a method for measuring diversity in medical reports written in any language, to compare diversities in narrative and structured medical reports and to map attributes and terms to selected ...
