Sand Topdressing Applications Improve Shear Strength and Turfgrass Density on Trafficked Athletic Fields

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

effect of particle crushing on shear strength and dilation characteristics of sand-gravel mixtures

there are limitations in experimental studies on sand-gravel mixtures due to the small size of testingspecimens. due to this problem, many researchers have worked on prediction of the shear strength of mixture by testingthe sandy fraction of soil alone and developed empirical relationships. most of the previous relationships have beendetermined for low surcharge pressures in which particle brea...

Measurement of faecal sludge in-situ shear strength and density

The provision of affordable urban sanitation presents a unique set of challenges as the lack of space and resources to construct new latrines makes it necessary to empty existing pits, typically done manually with significant health risks. Various mechanised technologies have been developed to facilitate pit emptying, which are currently either tested on faecal sludge or an ‘ad-hoc’ simulant th...

Comparison of Bone Mineral Density in Lumbar Spine between Athletic and Non-Athletic Premenopausal Women

Background & Aims: The purpose of the present research was to compare the bone mineral density (BMD) of lumbar spine between athletic and non-athletic premenopausal women. Methods: Fifteen female athletes (runner) with the mean age of 33.80 ± 4.81 years, mean height of 164.13 ± 5.31 cm, mean weight of 57.33 ± 4.22 kg, and mean body mass index (BMI) of 21.41 ± 2.21 kg/m2 and 15 female non-athlet...

Shear Fields and the Evolution of Galactic-scale Density Peaks

We present preliminary results of our investigation into the influence of shear fields on the evolution of galactic scale fluctuations in a primordial Gaussian random density field. Specifically, we study how the matter associated with a galaxy-scale peak evolves, to determine whether the shear can affect the peak’s ability to form a virialized structure. We find that the evolution of the mass ...
