The effect of aquatic plant abundance on shell crushing resistance
We also measured other factors that can affect crushing resistance, such as the density of crushing predators, snail density, water pH, and the concentration of calcium and phosphorus in the water. The isotope analysis suggested that snails assimilate water lily organic matter that is metabolized by sediment bacteria.
Abrasion Resistance an overview ScienceDirect Topics
Kumar (2017) investigated the effect of incorporating recycled concrete aggregates of two concrete mixes with two different w/c ratios at the age of 28 days by subjecting the specimens to the impingement of air driven silica sand and measuring the mass loss. He concluded that RA reduces the abrasion resistance by 18%–22%.

The Effect of Aquatic Plant Abundance on Shell Crushing Resistance
2012年9月6日The concentration of dissolved calcium (Ca) in water has been shown to affect crushing resistance in snails [18], so we included this variable in our analyses. The concentration of Ca in Cuatro Ciénegas is very high [42], [43] and therefore it should not limit shell crushing resistance in this area.
The Effect of Aquatic Plant Abundance on Shell Crushing Resistance
It is proposed that a third trophic level could be important in the coevolution of snail defensive traits and predatory structures because the local amount of water lily organic matter provides organic compounds important in shell biomineralization, thus determining crushing resistance. Most of the shell material in snails is composed of calcium
Effect of Calcium Carbonate Particle Size on the Scratch Resistance
2021年3月17日Polymer-based coatings are used for aesthetic purposes as well as to protect surfaces, especially under external conditions. High-hardness mineral fillers are thought to enhance the resistance of these polymer coatings to wear and scratching. However, recent studies suggest that the relatively low-hardness mineral calcite (CaCO3,
Chinese Mining and Indigenous Resistance in Ecuador
2021年9月20日The mining incursion by the Chinese-run subsidiary and the Ecuadorian security forces tasked with supporting it were seen as a threat to the area’s Shuar people, who have been strongly protesting and opposing the mining venture since late 2016. This state of affairs is likely to have far-reaching effects for Ecuador too.

1 For calcium-based desulfurizers, quicklime is typically selected as the desulfurizer, the specific surface area is about 5 m 2 /g, and the desulfurization effect is less than 10% (Cao et al., 2020). The desulfurization efficiency of ordinary slaked lime prepared by digestion is about 40%, and the specific surface area is 12 m 2 /g, showing low

Effects of calcium and resistance exercise on body composition
Conclusion: These results suggest that increasing dairy calcium offers no added benefit in reducing body fat when combined with resistance training and energy restriction. However, increasing dairy calcium improves bone mineral density in premenopausal overweight women. Publication types Randomized Controlled Trial Research Support, Non-U.S. Gov't
