Galoyan, V.R., 1978: Investigation of the torsional movements of the human eyes part 4 passive movements of the body effect of skeletal muscle reflexes opto kinetic torsional tracing. A comparative study of torsional movement of the eye in passive and active tilting of the head and body was performed. Similarity of torsional movement of the eyes in passive and active movements was shown. By exclusion and selective stimulation o...

This study correlated torsional strength reduction with circular defect size in cortical bone, to define the "stress riser" and "open-section" effect of the defects. The experimental model was developed and verified. Circular d...

Conjugated polymers represent a promising class of organic semiconductors with potential applications in a variety of molecular devices. Poly(3-alkylthiophene)s, in particular, are garnering interest due to their large charge carrier mobility and...

The torsional angle was calculated goniometrically of 9 femurs and 2 tibio-peroneal groups, and then compared to the values obtained from CT scans of the corresponding bones. The results show how the methods adopted up to now have been inaccurate...
