MUCH OF OUR PRESENT KNOWLEDGE about the species composition and distribution of ceph alopods of the Pacific Ocean is derived from collections made on cruises of the "Albatross," steamer of the U.S. Fish Comm ission, dur ing the late nine teenth and early twentieth centuries. "Albatross" collections along the west coast of North America were taken mainly off California and Central America or Ala...

This paper presents the results of a project that evaluated the potential of brush plating as a substitute process for hard chromium and nickel tank plating to reduce the quantity of waste generated during the repair and overhaul of gas turbine engines. The project was conducted dur ing 1992 by Sc ience App l i ca t ions International Corporation (SAIC) for Tinker AFB a n d t h e U . S . E P A ...

CLINICAL EPIDEMIOLOGY AS A DISCIPLINE has evolved rapidly dur ing the last decade. However, application of epidemiotogic principles in surgical clinical research has been limited. In the March 1996 issue of SURGERY we discussed the principles, application, and limitations of randomized clinical trials (RCTs) in surgery. RCTs are often viewed as the gold standard for evaluation of therapeutic ef...

Nuclear medicine would be greatly aided if compounds were available to promote the excretion of unwanted radioisotopes from biological systems. Such preparations would make possible greater use of long-lived radionuclides in medicine and would reduce some of the environmental hazards associated with nuclear energy. The biochemistry of radioisotope excretion is complicated because there are so m...

BACKGROUND AND OBJECTIVES Rocuronium is an intermediate nondepolarizing neuromuscular blocker (NMB) with faster onset and indicated in situations requiring rapid tracheal intubation. Intravenous lidocaine is often used to decrease hemodynamic responses to tracheal intubation. The association of NMB to local anesthetics results in potentiation of NMB effects. The purpose of this study was to eva...

This Commission was organized at the Rome Congress in 1908. The Central Committee of organization was fortunate in securing for its president a man of highest mathematical ability and one who was interested in all phases of the teaching of the subject,-—Professor Eclix Klein of Göttingen. The vice-president, Sir George Greenhill of London, represented mathematics chiefly as applied to physical ...

BACKGROUND A review update is necessary to document evidence regarding the effectiveness of computer-tailored physical activity and nutrition education. PURPOSE The purpose of this study was to summarize the latest evidence on the effectiveness of computer-tailored physical activity and nutrition education, and to compare the results to the 2006 review. METHODS Databases were searched for r...

The present study was designed to investigate whether absolute work rate (WR) affects Phase I pulmonary oxygen uptake (Vo(2)(p)) duration during moderate-intensity (Mod) exercise and to compare two methods for estimating Phase I Vo(2)(p) duration (P(I-Dur)). Fourteen males (24 ± 5 yr) each completed 4-8 repetitions of Mod transitions from 20 W to 50, 70, 90, 110, and 130 W. P(I-Dur) was identif...
