RESUMO
We report on the design, construction, and characterization of a 10 m-long high-performance magnetic shield for very long baseline atom interferometry. We achieve residual fields below 4 nT and longitudinal inhomogeneities below 2.5 nT/m over 8 m along the longitudinal direction. Our modular design can be extended to longer baselines without compromising the shielding performance. Such a setup constrains biases associated with magnetic field gradients to the sub-pm/s2 level in atomic matterwave accelerometry with rubidium atoms and paves the way toward tests of the universality of free fall with atomic test masses beyond the 10-13 level.
RESUMO
In a collective of 1012 patients (700 m., 312 f.), 346 (268 m., 78 f.) had pathological endoscopic findings in the bulbus. Diseases of the bulbus appeared in women about 10 years later than in men. In comparison to the endoscopic findings, roentgen findings showed disagreement in about 35% which mainly arose from contradictions in the assessment of cicatricial changes in the bulbus. False negative ulcer findings amounted to about 21%, the false positive to 19%. Endoscopic and histologically confirmed malignancies were not overlooked in a single case.
