The article shows the effect of torsional rigidity of beam elements onto spatial work of bridges, floorings and other plate-ribbed systems It is shown that, in determining the torsional rigidity using existing methods it is necessary to have spatial spiral cracks, but torsional rigidity when normal cracks is not researched. A method is described for determining the torsional rigidity of reinfor...

A new indole ring-terminated thiol, ω-mercaptooctyltryptamide (MOTA), has been synthesized and the structure of self-assembled monolayer (SAM) on Ag electrode was characterized by surface-enhanced Raman spectroscopy (SERS). The frequency of conformational marker W3 band has been found to increase by 3 cm–1 in surface spectrum as compared with the FT-Raman spectrum of solid MOTA compound, indica...

The Trp RNA-binding protein (TRAP) has a toroidal topology and a perfect 11-fold symmetry, which makes it an excellent candidate for a vibrational study of elastic properties. Normal mode analysis in combination with correlation matrix calculations was used to detect collective low-frequency motions in TRAP. The results reveal the presence of highly correlated modes at the lower end of the spec...

Torsional nystagmus was noted in a patient with hypothalamic hamartoma. Magnetic resonance imaging revealed an exophytic hypothalamic mass extending into the pre-pontine cistern and abutting ventral mesencephalon. The quickphase of the torsional nystagmus was directed towards the left side, ipsilateral to the side of compression by the hamartoma. Ipsi-lesionally directed pure torsional nystagmu...
