(www.interscience.wiley.com) DOI: 10.1002/qj.105 Variance scaling in shallow-cumulus-topped mixed layers
"... ABSTRACT: Scaling of thermodynamic variance in shallow-cumulus-topped mixed layers is studied using large-eddy simulation (LES). First, the performance of the top-down scaling (the turbulent flux at mixed-layer top divided by w∗) is evaluated for transient shallow-cumulus convection over land. The r ..."

Influence of Airway Diameter and Cell Confluence on Epithelial Cell Injury in an In-Vitro Model of Airway Reopening.
"... Recent advances in the ventilation of patients with the Acute Respiratory Distress Syndrome (ARDS), including ventilation at low lung volumes, have resulted in a decreased mortality rate. However, even low lung volume ventilation may exacerbate lung injury due to the cyclic opening and closing of fl ..."

Ninety patients (age range 49-99 yr) with a fracture of the neck of the femur were anaesthetized by a technique using halothane in oxygen in a closed circuit, halothane and 66 % nitrous oxide in oxygen in a Magill circuit or artificial ventilation with 66 % nitrous oxide in oxygen ("IPPV group& ..."

Data of ENT examination and the results of audiological examination by evoked otoacoustic emission have been used as a criterion of the course type and outcomes of hearing loss. The dynamics of the disease was evaluated in 2
