ACS releases updated guidelines on cancer screening.
Breast Cancer Early detection of breast cancer in average-risk women includes a combination of regular clinical breast examination and counseling, and mammography. Women between 20 and 39 years of age should undergo clinical breast examination every three years, and then annually beginning at 40 years of age. During clinical breast examination, physicians should discuss with patients the import...
متن کاملAcs New Energy Technology Symposium
T he fifth New Energy Technology Symposium was held at the 241st American Chemical Society (ACS) meeting at the Sheraton Park Resort in Anaheim, California on March 27 and 28. The organizer of the symposium, Dr. Jan Marwan of Dr. Marwan Chemie, was unable to chair the meeting due to personal reasons. However, the sessions of the symposium were co-chaired by Dr. Francis Tanzella of SRI Internati...
متن کاملA New Limit on CPT Violation ∗
A search for antiproton decay has been made at the Fermilab Antiproton Accumulator. Limits are placed on fifteen antiproton decay modes. The results are used to place limits on the characteristic mass scale m X that could be associated with CPT–violation accompanied by baryon number violation.
متن کاملACS Flat Field Update and New SBC L-flats
We present an overview of the methods used to create the flat fields which are currently in use by the ACS calibration pipeline. L-flats for the SBC detector have recently been computed using dithered star cluster observations. Large corrections to the existing flats are required at the 10-20 percent level, depending on wavelength. A comparison with sky flats obtained via observations of the br...
متن کاملNew limit on Lorentz- and CPT-violating neutron spin interactions.
We performed a search for neutron spin coupling to a Lorentz- and CPT-violating background field using a magnetometer with overlapping ensembles of K and ³He atoms. The comagnetometer is mounted on a rotary platform for frequent reversal of its orientation. We measure sidereal oscillations in the signal to search for anomalous spin coupling of extra-solar origin. We determine the equatorial com...
