The Impact

Peripheral facial paralysis (PFP) usually affects the facial nerve in part or in whole on one side of the face. Most patients with acute PFP find it difficult to chew on the paralyzed side, especially due to compromised buccinator function. In addition, the sagging of the ipsilateral lip commissure tends to compromise lip competence. The purpose of this study was to evaluate the impact of long-standing PFP upon mastication, relating to clinical mastication sidedness as determined by clinical and electromyographic activity of the masseters. The study included 27 male and female subjects aged 16−69 years with permanent natural dentition and long-standing PFP. Patients answered questions on their mastication habits before and after onset of PFP and were submitted to clinical myofunctional examination and electromyographical tests of the masseters during clenching and habitual mastication. According to the anamnesis, 77.8 % claimed to prefer chewing on the unaffected side. Clinically, 70% presented a lateral preference in mastication. In the clinical evaluation the buccinators and orbicularis oris differed significantly (p=0.025) between the healthy and the paralyzed side. Only 22.2% of the patients showed increased thickness of the contralateral masseters. No statistically significant electromyographic difference was observed between the masseters on the affected and unaffected side. Conclusions In general indicated that subjects with flaccid-stage PFP for 6 months or longer preferred to masticate on the unaffected side. No significant clinical or electromyographic differences were found in masseter activity between the affected and unaffected side in this patient sample.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

The Impact

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.
