While the Saudis — who are dedicated to enforcing stability in the region — have told Mr. Saleh he should go, the sudden change made it more difficult to structure an orderly handover of power and eventual elections.
In a decentralized system it is more difficult to structure career ladders, especially for workers who choose to locate in rural areas [ 81]; and decentralization can also exacerbate forms of patronage and political domination.
Indeed, we rely on structural alignments which are generally safer than sequence alignments, we use pairwise alignments rather than the more difficult multiple structure alignments, and we focus on comparisons between individual domains within superfamilies.
The use of inelastic pushover analysis and response spectrum approaches becomes more difficult when structures other than the framed ones are investigated.
Using guerilla strategy and cell phones, the PCC has evolved from a classic pyramid structure to the more difficult to penetrate structure of independent cells, much like a classic terrorist group.
"Certainly, if the flux continues to be so intense, it becomes more difficult to find structures.
A clear distinction of the different attachment sites is more difficult, but these structures are equally important and establish a direct connection between the surrounding ECM and the cell nucleus [ 87, 88].
This, however, needs to be confirmed using event-related paradigms and specific image acquisition and analytical techniques that allow the temporal course of activation to be quantified given that activation of the amygdala may show a rapid attenuation (Buchel et al., 1998) and functional activity within this structure is more difficult to image than within other cortical structures.
Also, the city's weakening fiscal outlook made a large subsidy for such a structure more difficult to justify.
Surface roughening results in reduced signal-to-noise, making observation of EDL structure more difficult.
