molecular diffusion of chloride ion through marl stone and sand stone

Experimental and Numerical Investigation of Reinforced Sand Slope Using Geogird Encased Stone Column

Among all of the slope stability methods, use of stone columns and geosynthetic elements can be a good way for stabilizing. One of the efficient ways in order to reinforce earth slopes is Geogrid Encased Stone Column (GESC). This technique can dramatically increase bearing capacity and decrease settlement rate. The aim of this paper is experimentally to investigate a comparison between the beha...

Production of artificial stone slabs using waste granite and marble stone sludge samples

In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...

Stone Composition in Patients Who Undergo Renal Stone Surgery: Review of 423 Stone Analyses in Southern Iran

Resource depletion through primate stone technology

Tool use has allowed humans to become one of the most successful species. However, tool-assisted foraging has also pushed many of our prey species to extinction or endangerment, a technology-driven process thought to be uniquely human. Here, we demonstrate that tool-assisted foraging on shellfish by long-tailed macaques (Macaca fascicularis) in Khao Sam Roi Yot National Park, Thailand, reduces ...

Stone in ureterocele peeping through ureteric orifice.

To cite: Prakash J, Goel A, Kumar M, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200168 DESCRIPTION A 42-year-old man presented with a 2-day history of severe colicky pain in the left flank with vomiting. X-ray (figure 1A) and ultrasonography showed a 13 mm left vesicoureteric junction calculus (figure 1B) with moderate hydroureteronephrosis and sma...

Fluoride ion adsorption onto palm stone: Optimization through response surface methodology, isotherm, and adsorbent characteristics data

In some part of the world, groundwater source can become unsafe for drinking due to the high concentration of fluoride ions [1]. The low cost and facile-produced adsorbent like palm stone could effectively removed fluoride ions through adsorption process. In this dataset, the influence of fluoride ion concentration, solution pH, adsorbent dosage, and contact time on fluoride ion adsorption by p...
