It forces the exhaust gases (produced when the fuel burned) out through the exhaust outlet (blue pipe). The whole cycle then repeats itself.How many cylinders does an engine need? One problem with the four-stroke design is that the crankshaft is being powered by the cylinder for only one ...
There are many types of apnea, and they are usually caused by problems in the respiratory centers of the brain. Diseases or conditions that minimize or prevent gas exchange: Pulmonary edema: Fluid between the alveolus and pulmonary capillary builds up, which increases the distance over which ...

Controlled operation comes only with many hours of ballooning experience. Now that we've seen how a hot air balloon flies through the air, let's look at the forces that make this possible. As it turns out, hot air balloons are a remarkable demonstration of some of the most fundamental ...
Finally, we examine how changes in curvature can influence transcriptional regulation through a reorganization of cytoskeletal forces acting on the nucleus, thereby facilitating the development of specific human diseases. Key points Cells interact with the curved surfaces of many organs and, at a lower...
There's only one Earth — unless you live in a comic-book multiverse— but there are many types of gyroscopes, each tailored to specific applications: Mechanical Gyroscope: A traditional design with spinning masses for stability, used in navigation and stabilization systems. Fiber Optic Gyroscope ...
The TCR integrates forces in its triggering process upon interaction with pMHC. Force elicits TCR catch-slip bonds with strong pMHCs but slip-only bonds with weak pMHCs. We develop two models and apply them to analyze 55 datasets, demonstrating the models’ ability to quantitatively integrate and...
During the 1991 Gulf war, allied forces knew of several underground military bunkers in Iraq that were so well reinforced and so deeply buried that they were out of reach of existing munitions. The U.S. Air Force started an intense research and development process to create a new bunker-bust...
There are dozens more, and who knows how many are living in the minds of tomorrow's comic book creators [source: Comic Vine]? Radiation Exposure Radiation is everywhere. It's been part of our environment since the planet was born. Radiation exists in the atmosphere, the ground, the ...
