The upcoming new perspective of the high redshift Universe in the 21 cm line of atomic hydrogen opens possibilities to explore topics of spiral disk evolution, hitherto reserved for the optical regime. The growth of spiral gas disks over Cosmic time can be explored with the new generation of radio telescopes, notably the SKA, and its precursors, as accurately as with the Hubble Space Telescope ...

This study investigated age-related differences in dynamic balance control and its connection to reflexes and explosive isometric plantar flexor torque in 19 males (9 Young aged 20-33 yr, 10 Elderly aged 61-72 yr). Dynamic balance was measured during Slow (15 cm/s) and Fast (25 cm/s) anterior and posterior perturbations. H/M-ratio was measured at 20% of maximal M-wave (H/M20%) 10, 30, and 90 ms...

INTRODUCTION Extra-focal or external fixation is the method of fracture fixation through the healthy part of the bone using pins or wires. OBJECTIVE The aim was to determine which external splints (Ortofix, Mitković, Charnley and Ilizarov) had the best biomechanical properties in primary stabilization of spiral, transverse and commutative bone fractures. METHODS To determine the investigati...

Synthetic dodecasill H, 34 Si02 . 3 M12 . 2 MI2 . 1 M20, with M12 and M12' = N2 and M20 =piperidine, is hexagonal with space group P6/mmm and a = 13.783(4) and e = 11.190(3) A. Structure refinement with 658 independent reflexions led to a weighted Rw = 0.056. The clathrate compound has a silica host framework and organic guest molecules M within three different types of cages. It is the simples...

OBJECTIVE Results of recent studies suggest a link between neuronal excitatory or inhibitory unbalance and depression. To investigate this relation, we studied the rest activity and the cortical excitability of the cerebral areas dedicated to hand control in 12 patients with depression. METHODS Brain activity was recorded from the Rolandic region in both hemispheres of 12 depression patients ...

24 25 This study investigated age-related differences in dynamic balance control and its connection to 26 reflexes and explosive isometric plantar flexor torque in nineteen males (9 Young aged 20-33; 10 27 Elderly aged 61-72). Dynamic balance was measured during Slow (15cm/s) and Fast (25cm/s) 28 anterior and posterior perturbations. H/M-ratio was measured at 20% of maximal M-wave 29 (H/M20%) 1...
