"I have not asked Charlie Rangel to come up here since his ethical difficulties surfaced," he said before denouncing his rival, Ms. Hayworth, for accusing him of donating $1,000 to Mr. Rangel, the dean of the New York Congressional delegation.
Market contagion and rating downgrades, starting when the magnitude of Greece's difficulties surfaced in early 2010, have become a self-fulfilling prophecy: by raising Portugal's borrowing costs to unsustainable levels, the rating agencies forced it to seek a bailout.
Later, with economic hardship, difficulties surfaced.
How is the difficulty surfacing?
But difficulties soon surfaced.
In this study this difficulty is overcome combining surface metrology and neutron tomography to guide the neutron diffraction measurements.
To overcome this difficulty, we adopt a response surface method (RSM) for the solution of nonlinear equation system.
To circumvent this difficulty, an approximation of the surface integral in terms of a domain integral has been proposed by the authors.
Fornberg and Piret developed a "QR-basis" that ameliorates this difficulty for approximations on the surface of a sphere, but because the recombined basis functions are perturbed spherical harmonics, not Gaussians, the Fast Gauss Transform is no longer applicable.
In front of this difficulty, the present study adopts response surface methodology to optimize the chemical compositions of protective agents to seek for maximum viability of Bifidobacterium longum BIOMA 5920 during freeze-drying.
Benthic diatoms represent an important element of global nutritional productivity; to raise attention on their role, which is often neglected due to analytical difficulties, surface (1 cm top layer) coastal sediments from Gerlache inlet to Penguin Bay at Terra Nova Bay were collected and stored at −20 °C.
