preoperative diagnosis of an airway obstruction should alert anesthetist to a potentially life threatening situation. intubation of the trachea while the patient is awa- ke or tra~heostomy under local anesthesia is a most useful technique and safty method in induction of anesthesia where problems are anticipated during the induction or g e ne r a l anesthesia.

The frame of an optimization model of coal alloction in a power generation group was introduced in present study. The influence of multi-coals blending and transportation were all considered in the model. Firstly, the impact of each process of coal using on the cost of power generation and boiler safety in the combustion process were analyzed, and the detailed mathematical descriptions were giv...

The selection of proper materials for different components is one of the most challenging tasks in engineer’s activity. The traditional approach to the selection of materials required looking through the literature and material safty data sheets.With the development of information technology, engineering work has also changed. It involves not only arduous browsing catalogues and guides but also...

A hierarchical control architecture for mission re-planning of autonomous underwater vehicle (AUV) navigating in uncertain ocean environment is presented in this paper. The proposed componentoriented control architecture structured is made of three parts: situation reasoning, re-planning trigger and hierarchical re-planning layer. Situation reasoning using the unstructured real-word information...

Background and aims: Many workers face significant hazardous workplace exposures, especially indeveloping countries. The objective of this study was to investigate the prevalence of occupational riskfactors and common occupational diseases in Kerman.Methods: This study was based on data from occupational risk factor and disease monitoring systemsavailable at Kerman Provi...
