This study numerically investigated the atomization characteristics of misaligned impinging jets, with misalignment ratio ê ranging between 0 and 0.2, by employing volume fluid method an adaptive mesh refinement algorithm. The results show that droplet Sauter mean diameter varies non-monotonically reaches minimum value, which implies best performance, at ê=0.1 under operating conditions concern...

OBJECTIVE To investigate the in vitro and in vivo antibacterial activities of tigecycline and other 13 common antimicrobial agents, alone or in combination, against multi-drug resistant Acinetobacter baumannii. METHODS An in vitro susceptibility test of 101 A. baumannii was used to detect minimal inhibitory concentrations (MICs). A mouse lung infection model of multi-drug resistant A. baumann...

INTRODUCTION Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB). Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients. METHODS Using a prospective, non-bli...

Basis set convergence of correlation effects on molecular atomization energies beyond the coupled cluster with singles and doubles (CCSD) approximation has been studied near the one-particle basis set limit. Quasiperturbative connected triple excitations, (T), converge more rapidly than L(-3) (where L is the highest angular momentum represented in the basis set), while higher-order connected tr...

Fractured root tips Roots break during extraction even when the most accomplished exodontist is at the helm. What separates the pros from the pretenders is how you handle it when it happens to you. Atomization (pulverization of roots with a bur on a high-speed handpiece), though described in some textbooks, is an imprecise and potentially dangerous way of dealing with stubborn root tips. The au...
