This study investigates the effect of cement on the performance of soil, collected from Khanjahan Ali Hall at Khulna University of Engineering & Technology (KUET) in Khulna, Bangladesh. The addition of cement was found to improve the engineering properties of available soil in stabilized forms specifically strength, workability, and compaction and compressibility characteristics. Therefore, lab...

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...

As a means of visualizing large-scale chromatin structure and dynamics our laboratory has used engineered chromosome regions tagged with lac operator repeats [1]. Recent progress in our laboratory focuses on analyzing multi-copy transgene arrays constructed from bacterial artificial chromosomes carrying 100-250 kb insertions of Drosophila or mammalian genomic DNA. These BAC transgene arrays not...

A 55-year-old man with acute congestive heart failure was referred to the echocardiography laboratory for evaluation of a dilated cardiomyopathy with severe left ventricular systolic dysfunction and criteria for non-compaction. Cardiac magnetic resonance imaging confirmed a non-compacted apical LV with segmental dysfunction and an inferior myocardial infarction. Coronary angiogram showed a chro...

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...

Compaction in sedimentary basins has been traditionally regarded as a one-dimensional process that ignores inelastic deformation directions orthogonal to the active load. This study presents new experiments with sandstone demonstrating role of three-dimensional compaction cyclic true triaxial compression. The were carried out on basis independent loading test system Laboratory Geomechanics Ishl...

This paper reports the results of model loading tests performed on an eccentrically loaded strip foundation supported by multi-layered geogrid-reinforced sand. Only one type of geogrid and sand at one relative density of compaction were considered. Based on the present laboratory test results, an empirical relationship for the reduction factor has been developed. This relationship can be used t...
