Title of Study: Earthen levee slide detection via automated analysis of synthetic aperture radar imagery Pages in Study: 111 Candidate for Degree of Doctor of Philosophy The main focus of this research is to detect vulnerabilities on the Mississippi river levees using remotely sensed Synthetic Aperture Radar (SAR) imagery. Unstable slope conditions can lead to slump slides, which weaken the lev...

This article presents experimental research work oriented toward developing practical design tools for industrial application, and illustrates the potential benefits of the synergistic effect of an ASTM C 618 Class F fly ash (FA) and a high-range polycarboxylate superplasticizer (SP) in the production of conventional concrete. The different concretes considered in this study were produced with ...

STUDY DESIGN Exploratory study of regional muscle activity in different postures. OBJECTIVE To detail the relationship between spinal curves and regional muscle activity. SUMMARY OF BACKGROUND DATA Sagittal balanced spinal posture (C7 above S1 in the sagittal plane) is a goal for spinal surgery and conservative ergonomics. Three combinations of thoracolumbar and lumbar spinal curves can be ...

Our objective is to produce a mechanically realistic model for the 1975 Kalapana event that explains the overall deformation and geological evolution of the south flank of Kilauea, and reproduces most known earthquake and tsunami observations. To do this, we present a new structural interpretation of geological data from Kilauea, along with modeling of the tsunami using recent seismic analyses....

Nonballistic, active range of motion exercises have been advocated as more effective than static stretching for increasing range of motion, yet no published data exist to support this claim. This study compared the effect of nonballistic, repetitive active knee extension movements performed in a neural slump sitting position with static stretching technique on hamstring flexibility. Forty healt...

in this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from isfahan steel mill for cement. the control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. the slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and th...

In Asia, many activities of daily living (ADL) are performed while sitting cross-legged on the floor. This sitting posture rotates the pelvis in a more dorsal direction and lumbar lordosis is more flattened than while sitting on a chair. Sitting cross-legged induces a greater load on the intervertebral discs and spine, especially when in a slumped position that is known to increase disc pressur...
