Gearing up for Robotics
This naturalistic, qualitative research investigated the extent and depth to which the perceived embedded educational skills and concepts associated with gears in a robotics environment were realized. The research literature revealed a paucity and confusion of description and definition of gears, and a lack of articulation of the embedded skills associated with gears. Based on some seminal rese...
متن کاملGearing up chromatin
D transcription, RNA polymerase may encounter DNA lesions, which causes stalling of transcription. To overcome the RNA polymerase blocking lesions, the transcribed strand is repaired by a dedicated repair mechanism, called transcription coupled nucleotide excision repair (TC-NER). After repair is completed, it is essential that transcription restarts. So far, the regulation and exact molecular ...
متن کاملVariable gearing in pennate muscles.
Muscle fiber architecture, i.e., the physical arrangement of fibers within a muscle, is an important determinant of a muscle's mechanical function. In pennate muscles, fibers are oriented at an angle to the muscle's line of action and rotate as they shorten, becoming more oblique such that the fraction of force directed along the muscle's line of action decreases throughout a contraction. Fiber...
متن کاملAnemia with Spur
of chenodeoxycholic acid, with small amounts of lithocholic acid present as well. Spur cells manifested a striking increase in cholesterol content and in the cholesterol: phospholipid ratio, but a normal osmotic fragility. When incubated in heated normal serum, spur cells lost their excess cholesterol and became spherocytic and osmotically fragile. Conversely, sera from patients with spur cells...
متن کاملOn Jack Phillip's Spatial Involute Gearing
This is a geometric approach to spatial involute gearing which has recently been developed by Jack Phillips (2003). After recalling Phillips' fundamental theorems and other properties, some geometric questions around this interesting type of gearing are discussed.
