Description of the previously unknown male of Systropha (Austrosystropha) macronasuta (Hymenoptera: Halictidae: Rophitinae) from Kenya [PDF]

open access: yes, 2017
We describe and illustrate for the first time the previously unknown male of Systropha (Austrosystropha) macronasuta Strand.  We provide a species diagnosis and modified couplets of the recent identification key to allow for easy identification of this ...

Meson-baryon threshold effects in the light-quark baryon spectrum [PDF]

open access: yes, 2008
We argue that selected $S$ wave meson-baryon channels may play a key role to match poor baryon mass predictions from quark models with data. The identification of these channels with effective inelastic channels in data analysis allows to derive a ...

Digital Image Analysis of Actinomycetes Colonies as a Potential Aid for Rapid Taxonomic Identification [PDF]

open access: yes, 2010
High frequency isolation of actinomycetes poses a challenge for the taxonomists hence simple and rapid identification methods are required. Our work to catalogue biodiversity of actinomycetes of Goa yielded several distinct morphotypes.
