To investigate the dynamic compaction mechanism of loess-filled embankment, a computational model of unit volume compaction effort was proposed as compared with the compaction test. The energy level of dynamic compaction used in actual projects was also considered. The differences between the compaction test and the unit volume compaction effort in the actual projects were studied. And also, th...

development of sensors to detect the location and depth of hard pans in real time is a major restriction on the application of site specific crop management (sscm). in this study, a soil compaction profile sensor equipped with four horizontal operating penetro-meters for on-the-go sensing and mapping of the location and intensity of hard pans arti-ficially formed in a soil bin was developed and...

The comments I offer in this memorandum on the MAC’s recommendations are limited to the issues listed below. In many cases, I agree with the MAC’s recommendations, and offer comments in order to contribute to broader debates about climate policy design in California, which will continue for years to come. There are also instances where I disagree with the MAC’s conclusions or believe the MAC fa...

Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

Nearly all economic models of the household have implications for how characteristics of the children in a family affect human capital investments in their siblings. Much evidence suggests that perceived returns to investing in sons is higher than investing in daughters in many economies (often due to cultural practices rather than inherent productivity differences). When this is so – and where...

Compaction of porous rocks can occur in two modes: uniform and localized. Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly...

The Mark II experiment first started taking data in 1978 at the SLAC SPEAR storage ring. It was the first e+edetector with a large, many layer cylindrical drift chamber (CDC) and a large liquid argon calorimeter!” After two years at SPEAR, it was moved to the PEP storage ring, where it was upgraded a year later with a seven layer precision vertex drift chamber!’ located between the CDC and the ...
