Abstract: Provided are methods and systems for delivering a treatment fluid to a wellsite. An example method includes receiving a container containing a treatment fluid component from a treatment fluid component supplier. The method further includes introducing the treatment fluid component into a wellbore from the container by pumping the treatment fluid component out of the container and into the wellbore. The treatment fluid component is not transferred to another container during the receiving or the introducing.

Abstract: A system for locating a region of varying density in biological tissue such as a breast includes a controlled x-ray source for directing x-rays through the breast, a phosphor screen positioned to receive x-rays exiting from the tissue and producing light in response thereto, a cooled, slow scan CCD camera, a variable magnification optical system positioned to receive light emitted by the phosphor screen and directing it to the cooled, slow scan CCD camera, a high resolution monitor, and a control system receiving signals from the cooled, slow scan CCD camera and digitizing the signals to produce digital data representative of the densities of various locations of the tissue.
