Mouth the mirror of lungs: where does the connection lie?

Jananni Muthu,Sivaramakrishnan Muthanandam,Jaideep Mahendra

Frontiers of Medicine 2016, Volume 10, Issue 4,   Pages 405-409 doi: 10.1007/s11684-016-0476-5

Abstract:

Periodontitis is the chronic destructive disease of the periodontium (Gums) caused by host bacterial interactions. The effect of such host bacterial interactions in oral cavity also evokes a systemic response. Numerous studies have found common mechanisms of destruction for periodontal diseases and other chronic diseases like diabetes mellitus, atherosclerosis, respiratory diseases, and adverse pregnancy outcomes. Oral colonization by respiratory pathogens appears to be a risk factor for development of respiratory diseases and oral interventions aimed at reducing oral bacterial count have resulted in reduced incidence of these reparatory illness. This reflects the importance of oral hygiene among patients with respiratory illness. This review highlights the association between periodontal diseases and respiratory diseases.

Handling Stability for Four-wheel Steering Vehicle Based on μ Synthesis Robust Control

Yin Guodong,Chen Nan,Li Pu

Strategic Study of CAE 2005, Volume 7, Issue 4,   Pages 54-58

Abstract:

The vehicles always undertake different loadings including external disturbances and the design of vehicle control system has model errors. The primary design techniques for 4WS controller are their inability to degrade the performance of closed-loop systems. The design of yaw rate tracking control system architecture by using μ synthesis robust control is presented and the weighting functions are selected. The results show that the control system has fine dynamic characteristic, robust stability and robust performance, and the 4WS vehicle with the proposed control strategy can provide greater maneuverability and driving safety.
