Now it's intrusive cell phones and road rage as social analogues of such evil cultural phenomena as women-hating rap lyrics and foul speech on "reality-based" television shows.
Vital information that is meant to remain confidential can be high jacked by an in intrusive cell phone left on to overhear sensitive conversations.
Siedlecka et al. [ 79] have shown that aspen pectin methyl transferases are involved in intrusive and symplastic cell growth in developing wood cells.
Though he illustrates the point with a comment about intrusive uses of cell phones in public spaces (2005, 47), the rise of mobile social networking has amplified this concern by several factors.
The 'snap point' the region of the stem (usually 6 8 cm from the SAM), where a sharp increase in stem mechanical strength protects it from breaking when pulled manually serves in flax as a good indicator of primary phloem fibre's developmental transition from intrusive growth to cell wall thickening (Gorshkova et al. 2003).
In the beginning of the intrusive growth stage, cell length in both the primary and the secondary phloem fibres is of the same range: ∼200 μm for primary fibres at the end of symplastic growth and ∼254 μm for cambial initials that give rise to secondary fibres.
The development of fibres was considered for a long time to combine cell-tip intrusive growth, ongoing even for months, simultaneously with secondary cell wall thickening of the 'older' central fibre part (Anderson 1927; Esau 1977; Fahn 1990).
Lawyers for detainees say that it traces back to a particularly intrusive search of their cells for contraband in which detainees were angered by guards' looking through their Korans, which they considered sacrilegious.
And when a romantic comedy has you idly reminiscing about Jack Klugman and Tony Randall -- when even Brazil's seductive landscapes and music can't hold your attention -- it's time to start eyeing the exits or longing for the intrusive trill of a cell phone.
It was believed for decades that while plant fibres grow by intrusive apical elongation they deposit secondary cell walls in the older, central parts of the cell (Esau 1977; Fahn 1990).
