A weight-management camp followed by weekly after-school lifestyle education sessions as an obesity intervention for Qatari children: a prospective cohort study
(
Elsevier
, 2015 , Conference Paper)
Background Weight-management camp interventions for obese children are eff ective for short-term weight loss. However, there is little evidence indicating how gains made with such interventions can be maintained in the ...
Residual shear strength of fine-grained soils and soil-solid interfaces at low effective normal stresses
(
Canadian Science Publishing
, 2015 , Article)
A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses ([1]3-7 kPa). Soils that cover a wide range of plasticity and ...
Estimating the elastic settlement of piled foundations on rock
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
