Examples "a negative outlook on life" "a colorless negative personality" "a negative evaluation" "a negative reaction to an advertising campaign" Used in print (William G. Pollard, Physicist and Christian....)The concept of unity , in which positive and negative are attributes of the same force , in which good and evil are relative , ever-changing , and always joined to the same phenomenon - such a concept is still reserved to the physical_sciences and to the few who have grasped the history of ideas . (Harry H. Hull, "The Normal Forces and Their Ther...)Two of the fluids showed a high positive normal pressure when undergoing shear , and two showed small negative pressures which were negligible in_comparison_with the amount of the positive pressures generated by the other two . The two fluids which gave the small negative pressures were polybutenes with molecular_weights which were stated to be 520 and 300 . It is presumed that this negative head was associated with some geometric factor of the assembly , since different readings were obtained with the same fluid and the only apparent difference was the assembly and disassembly of the apparatus . This negative pressure is not explained by the velocity head * * f since this is not sufficient to explain the readings by several magnitudes .

[ adjective ] reckoned in a direction opposite to that regarded as positive
Used in print (M. Yokoyama et al., "Chemical and serological...)For protein identification , fractions from the column were concentrated by pervaporation against a stream of air at 5 ` C or by negative pressure dialysis in an apparatus which permitted simultaneous concentration of the protein and dialysis against isotonic saline . Because negative pressure dialysis gave better recovery of proteins , permitted detection of proteins concentrated from very dilute solutions and was a gentler procedure , it was used in all but the earliest experiments . When paper_electrophoresis was to be used for preparation , eight strips of a whole serum sample or a chromatographic fraction concentrated by negative pressure dialysis were run / chamber under the conditions described above . Fractions from the column which were to be subjected to analytical ultracentrifugation were concentrated by negative pressure dialysis and dialyzed for 16 hr in the cold against at_least 500 volumes of phosphate buffered saline , pH 7.2 , ionic strength 0.154 . For preparative ultracentrifugation , fractions from the column were concentrated by negative pressure dialysis to volumes of 1 ml or less , transferred to cellulose tubes and diluted to 12 ml with isotonic saline .
