A Rare Presentation of Lemierre's Syndrome Caused by an Atypical Occurrence of Eikenella corrodens.

Lemierre's syndrome is characterized by a septic inflammatory condition involving internal jugular veins and is frequently caused by an oropharyngeal infection. While it usually results in pulmonary embolization, this case demonstrates a rare but significant cerebral embolization. The case involves an 18-year-old woman who experienced left-sided neck swelling and difficulty swallowing five days after a tooth extraction, an uncommon trigger.

Dynamic Performance of Partially Orifice Porous Aerostatic Thrust Bearing.

The aerostatic thrust bearing's performance under vibration brings certain changes in stiffness and stability, especially in the range of 100 to 10,000 Hz, and it is accompanied by significant increase in fluctuations due to the changes in frequency, and the size of the gas film damping. In this research work, an analysis is carried out to evaluate the impact of throttling characteristics of small size orifice on stiffness and stability optimization of aerostatic thrust bearings. There are two types of thrust bearing orifices such as: partial porous multiple orifice and porous thrust bearings and their effects on variations in damping and dynamic stiffness are evaluated.
