ausser der traditionellen nutzung der geothermalen energie sind in jungster zeit neue erkenntnisse und projekte in ausarbeitung, die fur die zukunft ausserst wichtig sein konnen. bei einigen dieser projekte hat man bereits einige sehr positive ergebnisse erzielt. ausserdem wurde klar, das die ausgaben fur exploration,und expleitaion wirtscnaftlich ohneweiteres vsrtretbar sind,j•a sogar in hinbl...

The target mass corrections are calculated for all structure functions of neutral and charged current deep inelastic scattering in lowest order in the coupling constant. Representations of the correction to the twist–2 and twist–3 contributions are derived both in Mellin-n and x-space. The impact of the target mass corrections on the general relations between the twist–2 and twist–3 parts of th...

Cis-regulatory modules (CRMs) function by binding sequence specific transcription factors, but the relationship between in vivo physical binding and the regulatory capacity of factor-bound DNA elements remains uncertain. We investigate this relationship for the well-studied Twist factor in Drosophila melanogaster embryos by analyzing genome-wide factor occupancy and testing the functional signi...

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...

BACKGROUND miRNAs are involved in osteosarcoma (OS) chemoresistance, and TWIST reportedly enhances cisplatin-induced OS cell apoptosis by inhibiting multiple signaling pathways. In this study, we profiled miRNAs differentially expressed in chemoresistant OS, with a focus to identify miRNAs that regulate TWIST expression and OS chemoresistance. METHODS OS patients who showed <90% tumor necrosi...

We investigate the helicity dependent twist-two and twist-three generalized parton distributions in light-front Hamiltonian QCD for a massive dressed quark target. Working in the kinematical region ξ < x < 1, we obtain the splitting functions for the evolutions of twist-two quark and gluon distributions in a straightforward way. For the twist-three distribution, we find that all contributions a...

The stabilization of the metastable 180 degrees twist state in a bistable chiral splay nematic liquid crystal device is studied. The stability of the metastable 180 degrees twist state is explained using the azimuthal anchoring strength, which is a function of the twist elastic constant and the cell gap. A stable 180 degrees twist state as well as the permanent retention time can be obtained by...

OBJECTIVES To compute left ventricular (LV) twist from 3-dimensional (3D) echocardiography. BACKGROUND LV twist is a sensitive index of cardiac performance. Conventional 2-dimensional based methods of computing LV twist are cumbersome and subject to errors. METHODS We studied 10 adult open-chest pigs. The pre-load to the heart was altered by temporary controlled occlusion of the inferior ve...
