Several studies have been aimed at elucidating the relationship between the activity of particular flor yeast enzymes during velum production, both in lab-scale and under winery conditions. For example, studies on the activity of alcohol and aldehyde dehydrogenase have... 

As noted previously, the main types of sherry (fino, oloroso, and amon-tillado) are produced employing different conditions. These differences result in significantly different polyphenolic composition. In the case of fino-type sherries, the layer of yeast that grows in the surface of the wine (flor velum) preserves its pale color. The velum limits the exposure of the wine from oxygen (Baron et ah, 1997). Hence, fino wines mature in a markedly reductive environment.

Allyl isothiocyanate (CH2=CHCH2N=C=S) has been studied as a contaminant in wine from discs treated with this substance. It is used at the surface of tanks to prevent the development of yeast velum, which is prohibited in most countries. We did not find allyl isothiocyanate in any of the wines studied. 

A 49-year-old man developed uvular deviation as a result of palatal muscle paralysis following intraoral mandibular block of the inferior alveolar nerve with 1.8 ml of 2% lidocaine with adrenaline 1 in 100 000 (96). A few minutes after injection he had swallowing difficulties and a foreign body sensation in his throat. There was paralysis of the velum palatinum, with deviation of the uvula towards the non-paralysed side opposite the point of anesthetic infiltration. This resolved after the anesthetic had worn off.

Initially attempts were made to build a model of the structure of the mesophase using large sheets of velum however, twisting of the layered structure of the phase was not easy achieved. Subsequent discussions with Jay Patel and Ron Pindak, however, led to the creation of various models of the phase where the helical structure was allowed to develop through the incorporation of defects. As this model was being developed a remarkable coincidence occurred. Ron Pindak produced a preprint from Tom Lubensky of a manuscript by Scott Renn and Tom Lubensky which presented a theory... 

Figure 7.3 Oral sounds are when the velum blocks the nasal cavity, and the sound escapes from the open mouth. Nasal sounds are caused, first by blocking sound escape from the mouth and secondly by lowering the velum so that sound can escape from the nose. Nasalised sounds have sound escape from both the mouth and nose.

The velum is a piece of skin at the back of the mouth. When it is raised, the nasal cavity is blocked off and the speech is completely oral. When the velum is lowered, the sound will be nasal or nasalised, depending on if the mouth is closed or open. It is important to note that in an oral... 

When the velum is lowered during the production of nasals and nasalised vowels, sound enters via the velar gap, propagates through the nasal cavity and radiates through the nose. Hence for a more complete model, we have to add a component for the nasal cavity. This in itself is relatively straightforward to model for a start, it is a static articulator, so doesn t have anywhere near the complexity of shapes that occur in the oral cavity. By much the same techniques we employed above, we can construct an all-pole transfer function for the nasal cavity.
