Improving Valve Representation in Cardiac Stereolithography by Spatially Registering Magnetic Resonance Imaging and Echocardiography Tyler Robert Moore MDa, Erin Janelle Madriago MDb, and Michael Silberbach MDb Introduction Additive manufacturing, a means of fabricating objects layer by layer though extrusion or sintering, has the potential to impact biomedical research, patient imaging, and medical therapies. One example is personalized anatomic modelling, the
Before the hiatus, I made an attempt at creating a Continuous Fluid Density Sensor. Here are the primary components: Two dip tubes in the fermenter MPXV7002DP differential pressure sensor ADS1115 16-bit analog to digital converter Generic, chrome plated brass, 2.5 mm hose barb to M3 adapters and 2.5 mm pneumatic hose Generic 12V aquarium diaphragm pump (model no longer listed
Introduction One of the chores every brewer performs is measurement of the density of a fluid. This measurement gives two critical data from the brewing process. First, a measurement right before fermentation tells how much sugar is in the wort. This is called original gravity and is one of the key parameters of any beer recipe. A large portion of the
The recipe for beer is pretty simple. One important step is boiling the wort, the sweet mixture that yeast will ferment into beer. Boiling sanitizes the beer so that yeast can work its magic, but not before the wort is cooled back down or the yeast meets the same quick, steamy end as its potential competitors. There are many ways to
