Communications to the Editor this device in a previously reported randomized study.’ The methods we used2 to perform MV were nearly the same as those used in that study, but the strategies of tracheal aspiration and instillation were quite different. We performed tracheal aspiration systematically at least every 4 h. This strategy led us to instill 30±12 mIld in the heated-humidifier (Hil) grou...

Two new species of the syringophilid mites (Acari: Syringophilidae) are described from quills of passeriform birds. Syringophilopsis faini sp. n. is described from Sylvia curruca (L.) (Sylviidae) and Syringophiloidus carpodaci sp. n. is described from Carpodacus erythrinus (Pall.) (Fringillidae). Characters are detailed that differentiate Syringophilopsis faini from three species of a new "turd...

The herbaceous peony (Paeonia lactiflora Pall.) has high ornamental and nutritional value, the seeds of P. can be used to produce high-quality edible oil. However, low seed yield limits application lactiflora. This mitigated by insect pollinators. Here, we evaluated pollination services honeybees (Apis mellifera L.) in a field. We found that A. provided for throughout day especially period from...

The Workshop was asked by Pall Corporation to consider ways in which membrane morphology may be characterized, and how such characterization can be used to assess filtration efficiency. The working group considered a variety of different (but related) approaches, which are outlined below but which will be described in more detail in the forthcoming report. 1 Darcy flow model In an effort to cha...

Contaminant exposure can vary between species but primary causes of it are often unclear. In order to estimate heavy metal intake of two sympatric passerines - Ficedula hypoleuca Pall. and Parus ater L. - we studied nestling diet and metal concentrations in prey invertebrates, near the Middle Ural copper smelter and in an unpolluted area. Diet of P. ater contained more Cu, Cd and Zn compared to...
