On Aug 24, 2009, the online-only Engineering Design Graphics Journal (the Journal) was launched (see http://www.edgj.org) following an eighteen month self-study. The self-study began Feb 2, 2008 when the then Engineering Design Graphics Division Executive Committee Chair, Kathryn Holliday-Darr, issued…

Purpose. Time series analysis may be helpful to estimate hematological data on gastric cancer patients who receive S 1, but untreated raw clinical data are not suitable for this approach. Hematological monitoring data interpolated by spline were analyzed by an…

‘Araphid’ diatom classification is discussed from the point of view of an ‘absolute standard’ for taxonomic rank. The absolute standard is the phylogenetic tree, its nodes, the included monophyletic groups and sub-groups. To illustrate this point a few species from…

A new small-size species of Sellaphora was found in sediments from Hannaberry Lake, Arkansas, during the National Lakes Assessment project conducted by the United States Environmental Protection Agency. The species was studied with light microscopy and scanning electron microscopy. It…

Descripción completa.

The integrity of all sedimentary diatom assemblages is influenced to some degree by taphonomic processes. Recognising these processes with regard to preservation pathways for diatom assemblages and for individual species can be instructive for interpreting sediment core diatom records. Diatoms…

The present study examined by light microscope the morphological variations of 625 specimens of Gomphonema ventricosum Gregory collected from Lake Hövsgöl (Mongolia), Lake Baikal (Russia) and Lake Kurilskoye (Kamchatka, Russia). We classified the specimens into five types with respect to…

Two new Mesodictyopsis species, M. akitaensis sp. nov. and M. miyatanus sp. nov., are described from freshwater sediment of the Late Miocene to Pliocene Miyata Formation, northern Honshu, Japan. The species are characterized by small size, veluma on inner side…

Large numbers of diatom taxa are currently being described each year and molecular data sets are providing phylogenetic evidence that challenges the traditional systematic arrangement of diatoms, but is such information being integrated into the classification? The traditional diatom classification…

A new Amphora species, Amphora soninkhishigae sp. nov. is described from the saline lakes, Oigon Nuur and Uvs Nuur, in western Mongolia. Amphora soninkhishigae is characterized by its small size (valves 12–28 mm long, 2.9–3.8 mm wide), fine ornamentation, and…
