The excess flesh of the body of one or both partners would simply prevent procreation because it would obstruct penetrative sex, either fully as suggested by Barrough above, or partially as penetration might not be as deep into the vagina as was needed to cast the seed into the womb.
In fact, the softness of the fibres makes the cavitation to produce small erosion effect and the reticulate structure of the fabric favours the formation of air bubble layers which obstruct wave penetration.
For example, plants often have very specific mechanisms to prevent fungal pathogens from entering leaf tissue [ 6] and some species produce layers upon their epithelium - the first barrier against infection - to obstruct parasite penetration (for example, mucus in coral protection [ 7] or salivary mucins to preserve the oral cavity health [ 8]).
In the cases of oral leukoplakia, the intraepithelial papillary capillary loop can't usually be observed owing to the fact that the hyperkeratosis of oral leukoplakia obstructs the penetration of light and the focus of observation has to be emphasized on the mucosa around the whitish patch [ 5, 6, 8, 9].
Of all the five industrial dyes considered for the photocatalytic degradation study, the degradation efficiency for brilliant blue was minimum (Fig. 7a) due to the complexity in molecular structure and strong coloring properties, which obstruct the light penetration in aqueous media.
And in this ways it works as a barrier to obstruct the attacker against penetration.
In summer, it reduces the penetration of unwanted radiation without obstructing the view through the window, to an extent that may render external shading devices unnecessary.
Extensive use of these methods is obstructed by tissue formation around the scaffold, hindrance in cell penetration and time required for cell coverage within the scaffold.
In Yemen, the author said free speech was abridged and democracy obstructed although the larger picture showed the Internet recorded low penetration and its impact was indirect.
Cement penetration into the graft material should be limited because excessive cement penetration would obstruct bone ingrowth into graft material.
