background: various studies are seeking to find new methods to improve techniques of laryngeal mask airway (lma) insertion and reduce possible complications. in this study, we embarked on a clinical study to investigate the advantages of a new insertion method of laryngeal mask and to compare it with the classic method. materials and methods: two hundred patients aged 20-60 years old in 2012 we...

computers are used everywhere from home to work these days, thus the effects on the visual system will be more noticeable every day. problems associated with computer usage are generally known as the computer vision syndrome (cvs).these problems include eye fatigue, irritation ,redness , blurred vision and dry eye. all of these problems have adverse effects on individuals in the long term and r...

eye movement desensitization and reprocessing (emdr) process encompasses several nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes. the role of eye movement (em) has been documented previously in relation with cognitive processing mechanisms. by emdr we can reach some parts of memory which were inaccessible before and als...

Ten junior doctors with no postgraduate anaesthetic experience attempted to ventilate the lungs of 50 anaesthetized patients, using either a laryngeal mask or a Guedel airway and face mask. Success was defined as the production of two successive tidal volumes exceeding 800 ml within 40 s. The failure rate was significantly greater using the laryngeal mask compared with the face mask (P < 0.05) ...

Increasing design complexity in sub-90nm designs results in increased mask complexity and cost. Resolution enhancement techniques (RET) such as assist feature addition, phase shifting (attenuated PSM) and aggressive optical proximity correction (OPC) help in preserving feature fidelity in silicon but increase mask complexity and cost. Data volume increase with rise in mask complexity is becomin...
