A passive false twist unit (spiral) has been developed to assist with the handling lowstrength slivers on a high speed-spinning machine with a high-speed feed. In the first trial, a falsetwist simulator device was constructed to determine whether the passive false twist unit can be usedon high speed feeding with different can distance from the feeding device. In the second trial, theeffects of ...

OBJECTIVE Left ventricular (LV) rotation and twist play an important role in LV contraction and relaxation. Left bundle branch block (LBBB) deteriorates both diastolic and systolic functions. We evaluated the LV twist in patients with LBBB and preserved ejection fraction (EF) (>50%) to determine twist as a potential marker for subtle myocardial dysfunction. METHODS This observational cross-se...

An ensemble of screws is known as a screw system, and is deened by a set of n 6 independent basis screws. The order of a screw system is equal to the number of basis screws required to deene it; such a system is also called an n-system. The order of a screw system reciprocal to an n-system is (6 ? n). With an innnitesimal rigid motion of an object in three-dimensional Euclidean space there is a...

Both TWIST and the endothelin-1 (ET-1)/endothelin A receptor (ETAR) signaling are important in osteosarcoma (OS) progression. In the present study, the interaction between TWIST and ET-1/ETAR signaling in OS cells was investigated, and the impact of the functional interaction on OS cell survival against chemotherapy agent-induced apoptosis was assessed. TWIST was overexpressed and knocked down ...

Most liquid crystal displays make use of the elect roopt ic properties of twisted nematic layers. Both the s tandard twisted nematic displays of 90° twist [1] as well as the recently developed 'supertwist ' displays of more than 180° twist [2] require director fields which depend only on one spatial coordinate, the coordinate z parallel to the layer normal. Director fields which depend on more ...

A bstract Sum rules for structure functions and their twist-2 relations have important roles in constraining magnitudes x dependencies studying higher-twist effects. The Wandzura-Wilczek (WW) relation the Burkhardt-Cottingham (BC) sum rule are such examples polarized g 1 2 . Recently, new twist-3 twist-4 parton distribution were proposed spin-1 hadrons, so that it became possible to investigate...

I discuss the relation between the Qiu-Sterman effects on one hand and the Collins, Sivers and Boer-Mulders effects on the other hand. It was suggested before that some of these effects are in fact the same, thus providing interesting connections between transverse-momentum dependent twist-2 functions and collinear twist-3 functions. Here I propose an alternative way to reach similar conclusions.

We investigate the twist-3 transverse-momentum-dependent parton distribution functions (TMDs) of pion with basis light-front quantization. The TMDs are not independent and can be decomposed into twist-2 genuine terms from equations motion (EOM). compute resulting wave obtained by diagonalizing QCD Hamiltonian, determined for pion's constituent quark-antiquark quark-antiquark-gluon Fock sectors,...

The Octant Rule1 provides a theoretical basis for the study of optical rotatory dispersion curves of ketones. The application of this rule to extensive collections of data for cyclohexanone types from our two laboratories has been described elsewhere.2 3 Among the hundreds of curves recorded, a few stand out by reason of their unusually large amplitudes (positive or negative), which cannot be r...

we have recently synthesized ti(bh4)3(thf)3 and v(bh4)2(tmeda)2 complexes. the reaction of ticl3(thf)3 with nabh4 in dry thf gave flat blue crystals, ti(bh4)3(thf)3. the reaction of vcl3 with nabh4 in presence of n, n, n', n'- tetramethylethylenediamine, tmeda, produced violet crystals, v(bh4)2(tmeda)2. vibrational and magnetic properties of ti(bh4)3(thf)3 and v(bh4)2(tmeda)2 have been studied.
