Sticking together: The occupation of different sites by oxygen atoms that are produced by the dissociation of O(2) on Pd(100) is determined by the initial rotational alignment of the parent molecules. The atom locations are characterized by different chemical reactivities in the reaction with CO to form CO(2) (see picture), which are followed by synchrotron radiation (SR) experiments with a sup...

Rang highlighted many of the practical aspects of caring for children's fractures, including forearm fractures. Contrary to the forearm shaft fracture rotational dogma of others, Rang said, “Immobilize the fracture in the position—any position [rotation]—in which the alignment is correct and the reduction feels stable. He also discussed the value of single-bone internal fixation with a Kirschne...

We experimentally demonstrated that both the electronic Kerr effect and the molecular alignment in gaseous molecules could be applied as transient gates to diagnose 400 nm target pulses. Their birefringence dissimilarity was clearly visualized by the measured spectrogram and retrieved gate function. In the atomic gas argon, a relatively weak and instantaneous cross phase modulation within the p...

We show the possibility of simultaneously aligning molecules and focusing their center-of-mass motion near a metal nanoparticle in the field intensity gradient created by the surface plasmon enhancement of incident light. The rotational motion is described quantum mechanically while the translation is treated classically. The effects of the nanoparticle shape on the alignment and focusing are e...

We have experimentally and theoretically investigated the mixed-field orientation of rotational-state-selected OCS molecules and achieved strong degrees of alignment and orientation. The applied moderately intense nanosecond laser pulses are long enough to adiabatically align molecules. However, in combination with a weak dc electric field, the same laser pulses result in nonadiabatic dynamics ...

The neutron deficient Tb nucleus has been studied with the Mo (Fe, αp) reaction at 240-MeV incident energy and the multidetector array GASP. For the yrast πh11/2 decoupled band, excited states up to 6.7 MeV and spin up to 47/2− have been observed. This band presents an upbend at rotational frequency of ~ω = 0.38 MeV due to the alignment of h11/2 protons. The results are discussed in terms of th...

Intoed and out-toed gait in children can occur due to foot deformities or torsional alignment of the femur and/or tibia. In most cases, these are physiological resolve with age. Physical examination consists assessment rotational profile lower limb which includes progression angle, tibia, shape. Few cases may be underlying pathological conditions need identified treated.

We report a substantial increase of the rate of internal relaxation in dust grains containing superparamagnetic inclusions. The effect arises from the increase of dissipation induced by the Barnett effect. The increase of the internal relaxation induces higher coupling of the rotational and vibrational degrees of freedom of grain with important consequences to thermal trapping of grains. In ter...

BACKGROUND Lower limb rotational anomalies in spastic diplegic children with cerebral palsy (CP) are common and difficult to identify through physical examination alone. The identification and treatment of the overall rotational disorders must be considered to restore physiological lever-arms lengths and lever-arms orientation.The aims of the study were to assess the prevalence of lower limb ro...
