conclusion a high rate of mrsa in both community- and hospital-acquired infections were observed. background staphylococcus aureus (s.aureus) is an importantpathogen in human infections.some strains of s.aureusare methicillin-resistant (mrsa) andcause hospital- and community-acquired infections in children. the aims of this study were to determine nasalcarriage rate of s. aureus and susceptibil...

Designing reliable CMOS chips involve careful circuit design with attention directed to some of the potential reliability problems such as electromigration and hot carrier e ects. This paper considers logic synthesis to handle electromigration and hot carrier degradation early in the design phase. The electromigration and the hot carier e ects are estimated at the gate level using signal activi...

choanal polyps are a form of nasal polyps that grow toward the choana with a single stalk. septochoanal polyp is a rare entity that originates from the mucosa of the nasal septum with choanal extension. the most common site of its origin is mainly the superior aspect of the posterior portion of the nasal septum. however, metaplastic ossification is a rare event in nasal polyp and to the best of...

This paper presents a Multi-Carrier Pulse Width Modulation control for a Single-phase 27-level Hybrid Multi-Level Inverter for photovoltaic systems. Multi-Carier Pulse Width Modulation technique uses a easy mapping to generate gate signals for the inverter.The Maximum Power Point Tracking is capable of extracting maximum power from PV array connected to each DC linkage voltage stage. The Maximu...

the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...

introduction rhinoliths are uncommon nasal masses. they are mineralized masses found within the nasal cavity. they have various clinical presentations. case presentation we report a 13-year-old boy with long-standing nasal obstruction, yellowish nasal discharge and intermittent and minimal nasal bleeding for a few weeks, who had been treated as rhinosinusitis twice. due to the presence of long-...

in crooked noses, the lateral walls are different in shape and symmetry. although the septum is very important to obtain a straight nose, identical and symmetrical lateral walls are needed for a straight looking nasal dorsum. as well as the septum, lateral walls also contribute in nasal skeletal support and stability. thus, obtaining identical and symmetrical lateral walls is important. in orde...
