We present a generalized optical theorem for surface waves. The theorem also applies to body waves since under many circumstances body waves can be written in terms of surface-wave modal summations. This theorem therefore extends the domain of applicability of the optical theorem from homogeneous background media to a general class of body and surface-wave propagation regimes within layered ela...

Pearson's 2 ! and the Likelihood-ratio statistic 2 G are the most common and widely used test statistics for log-linear models. They are both asymptotically distributed as chi-squared variables. The present article reports the results of a Monte-Carlo study which compares the two test statistics for two-, threeand four-dimensional contingency tables, employing conditions which may be judged rea...

At approximately 100 days of gestation, 45 Angus x Hereford and 10 Hereford heifers were assigned either to be implanted with 36 mg zeranol or to serve in a control group. Monthly measurements revealed no effect of treatment on body weight. Increased pelvic area was observed during the first (P<.05), third (P<.05) and fourth months (P<.01) after zeranol treatment. Calf birth and weaning weights...

To evaluate effects of previous forage systems on feedlot performance, yearling Hereford steers (average initial weight of 249 kg) were grazed on tall fescue (TF), smooth bromegrass-red clover (BG-RC) or orchardgrass-red clover (OG-RC) pastures before finishing. Serial slaughter was utilized during the first 2 yr of this study to determine changes in carcass characteristics throughout finishing...

OBJECTIVE To assess the safety of increasing the number of waves per session in the treatment of urolithiasis using extracorporeal lithotripsy. MATERIAL AND METHODS Prospective, comparative, nonrandomized parallel study of patients with renoureteral lithiasis and an indication for extracorporeal lithotripsy who were consecutively enrolled between 2009 and 2010. We compared group I (160 patien...

Clinical and experimental data have documented the ability of nontransmural myocardial infarction to produce abnormal Q waves on both the epicardial and body surfaces. We undertook this study to define the anatomic determinants of such Q wave development. Thirty dogs were studied before and after occlusion-reperfusion (26 dogs) or latex embolization (four dogs) of the left circumflex coronary a...

The popularity of high-protein diets for weight reduction is immense. However, the potential benefits from altering the source of dietary protein rather than the amount is scarcely investigated. In the present study, we examined the effects of fish protein supplement on glucose and lipid metabolism in overweight adults. A total of thirty-four overweight adults were randomised to 8 weeks' supple...

A numerical method to deconvolve complex body waves into a multiple shock sequence is developed. With the assumption that all the constituent events of a multiple shock have identical fault geometry and depth, the far-field source time function is obtained as a superposiUon of ramp functions. The height and the onset time of the ramp functions are determined by matching the synthetic waveforms ...

Abstract Usually, evanescent modes or non-propagating waves are produced when a propagating incident wave impinges on an interface between two media or materials such as curtainwall-pile breakwater (CPB) at a subcritical angle and decay with distance from interface. To achieve an effective prediction of hydrodynamic performance of CPB and overcome the problem of underestimation of energy loss, ...
