Having a LAFF with Anthracoidea

Nonlinear dynamic analysis of a four-bar mechanism having revolute joint with clearance

In general, joints are assumed without clearance in the dynamic analysis of multi-body echanical systems. When joint clearance is considered, the mechanism obtains two uncontrollable degrees of freedom and hence the dynamic response considerably changes. The joints’ clearances are the main sources of vibrations and noise due to the impact of the coupling parts in the joints. Therefore, the syst...

The identity of Cintractia carpophila var. kenaica: reclassification of a North American smut on Carex micropoda as a distinct species of Anthracoidea

Cintractia carpophila var. kenaica, a neglected taxon described from Alaska more than half a century ago, is re-described and illustrated. Its nomenclature and taxonomic status are discussed. This smut species is characterised by small spores with a very finely verruculose surface rarely enclosed by a thin, hyaline, mucilaginous sheath, a wall with 2-5 distinct internal swellings, and parasitis...

Firstly, I should like to pay tribute to the nurses working in the maternity wards, w...
