    The effect of walking and vitamin B supplementation on quality of life in community-dwelling adults with mild cognitive impairment: a randomized, controlled trial
  2. 242
    por Lüttge, Ulrich
    Publicado 2010
    “…This requires more plastic spatio-temporal responsiveness and versatility in the acquisition and defence of ecological niches. CRASSULACEAN ACID METABOLISM: The mode of photosynthesis of crassulacean acid metabolism (CAM) is described and its flexible expression endows plants with powerful strategies for both acclimation and adaptation. …”

    Wet Air Oxidation of Oil Shales: Kerogen Dissolution and Dicarboxylic Acid Formation
  4. 244
    “…Different formation stages of calcite and Fe-oxide concretions observed, both in Utah and Mongolia, indicate that calcite concretions initially formed within eolian sandstone strata and were dissolved by infiltrating Fe-rich acidic waters to form spherical FeO(OH) crusts due to pH buffering. …”

    Interaction between a Martian Regolith Simulant and Fungal Organic Acids in the Biomining Perspective
  10. 250
    “…The results indicate the synergy effect of reducing the acid concentration and surfactant adsorption on rock surfaces can lead to an obvious enhancement of the fracture permeability after acidizing, while the mud acid or hydrofluoric acid is not suitable for the target reservoir where concentrations of silicates and clays are relatively high.…”

    Optimization of Fracturing Fluid and Retarded Acid for Stimulating Tight Naturally Fractured Bedrock Reservoirs
  11. 251
    “…This conversion is consistent with their enrichment compared to amino acid analogs in heavily altered CCs. Our results thus suggest that H(2) can be an important driver for organic evolution in water-rock differentiated CC parent bodies as well as the Solar System icy bodies that might possess similar pH and redox gradients.…”

    por Li, Hao, Shi, Yongmin
    Publicado 2020
    “…Understanding the relationship between the individual factors (i.e., carbonate rock types, acid rock reaction kinetics, and deterioration of rock mechanical properties) can provide practical guidelines that can be used for the design and optimization of acid fracturing operation. …”
