Application of theories for spectral line formation to quantitative interpretation of solar magnetograph readings
Lunar mascons, interpreting lunar gravitational field anomalies over maria in terms of near- surface slab-like model for maria structure
Discrete source hypothesis for interpreting high energy cosmic gamma ray measurements obtained by OSO-3 spacecraft
Continuum fracture concept indicating essential surface energy interpretation difference in otherwise similar adhesive and cohesive failures
Instrumentation and data interpretation method for particle size determination by low-angle light scattering
Reference of X-ray film images provides examples of weld defects, film quality, stainless steel welded tubing, and acceptable weld conditions. A summary sheet details the discrepancies shown on the film strip. This reference aids in interpreting and evaluating radiographic film of weldments.
