The effect of a "Nuisance" dust inhalation on lung clearance
, 2022 For particles which show low solubility and/or slight biological effects a general threshold limit is applied in the occupational field, e.g. 6 mg/cubic meter (FRG) and 5 mg/cubic meter (USA). In this study the effect on lung retention and lung clearance

Developmental toxic effects of ethylbenzene or toluene alone and in combination with butyl acetate in rats after inhalation exposure [PDF]
, 2007 First, the developmental toxic potential of n-butyl acetate (BA) was examined in Sprague-Dawley rats following whole body inhalation exposure, 6 h day-1, from day 6 to 20 of gestation, at concentrations of 0, 500, 1000, 2000 and 3000 ppm.

Advanced Robotics Research, EarlyView.A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

Ultrastructural observation in hamster and rat lungs after chronic inhalation of cadmium compounds
, 2022 S.264-268Long-term inhalation of CdCl2 at concentrations as low as 12.6 myg Cd/cbm causes development of lung tumors in rats (4). No information, however, was available on the chronic carcinogenicity of CdO, CdS and CdSO4 which are especially relevant to

Machine Learning for Green Solvents: Assessment, Selection and Substitution
Advanced Science, EarlyView.Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,
