FLEXIBLY DIVIDED DOUBLE LUMEN ENDOTRACHEAL TUBE Viren Sunil Kalsekar‚ Joy Lee‚ Jenny Qiu‚ Nicholas Ragosta‚ Javier Ramos‚ David Taylor Massachusetts Institute of Technology Cambridge‚ MA‚ USA ABSTRACT Endotracheal tubes (ETT)‚ are used to maintain patient airway access during surgical procedures. The design presented here addresses a current need of the gold standard ETT by allowing for the passage of a larger bronchoscope through the inner lumen of the ETT while keeping outer dimensions constant

Introduction In this experiment‚ the gram negative bacterium Escherichia coli is being subjected to various environmental factors that affect the rate of growth. These factors scrutinized were the different types of nutrients‚ the intensity of aeration‚ or the temperature at which it was stored. The purpose of this lab is to determine which factor affects the Escherichia coli the greatest. It is known that these abiotic factors affect the rate of growth the greatest if they remain at the correct

In a normal pregnancy‚ a fertilized egg travels from the location of fertilization (the fallopian tube) to the uterus. Sometimes however‚ the egg grows in the wrong place‚ which is known as an ectopic pregnancy.

If a diver performs a forceful Politzer maneuver‚ the eustachian tube will open. This causes the pressure in the middle ear to increase. The ossicles will suddenly return to their normal positions‚ causing the round window to
