Metals content affects not only for nutritional value of plants, but also their resistance to stress. So it was revealed that cationic composition changes hydration cytoplasm. Hydration cytoplasm positively correlated with alkali metals, a representative which is potassium, and negatively amount alkaline earth metals (calcium, magnesium). Variability rice collection samples in terms sodium, cal...

PURPOSE Hydroxypropyl guar (HPG) and hyaluronic acid (HA) have been individually shown to improve dry eye symptoms. The purpose of this in vitro study was to assess the potential benefits of a new lubricant eye drop formulation containing the demulcents propylene glycol and polyethylene glycol and an HA/HPG dual polymer in models of the human corneal epithelium. METHODS Cultured human corneal...

Earlier studies have demonstrated the beneficial effects of adding Ordinary Portland Cement (OPC) to bitumen emulsion mixtures. These effects were confirmed for some dense graded mixtures based on recipes currently used for hot mix in the UK and being considered for use in cold mix. Laboratory tests included stiffness modulus, resistance to permanent deformation and resistance to fatigue cracki...

In the recent years, the biophysical properties and presumed physiological role of aquaporins (AQPs) have been expanded to specialized cells where water and solute exchange are crucial traits. Complex but unique processes such as stomatal movement or pollen hydration and germination have been addressed not only by identifying the specific AQP involved but also by studying how these proteins int...

The major hydraulic phase in all the calcium aluminate cements including ciment fondue is CA (CaAl2O4). Once hydrated, it starts to form the hexagonal crystals of CAH10 and C2AH8 that depending on the time and temperature of hydration convert to the cubic crystals of C3AH6 and AH3. The nature, sequence, ...

From soft polymeric gels to hardened cement paste, amorphous solids under constant load exhibit a pronounced time-dependent deformation called creep. The microscopic mechanism of such phenomenon is poorly understood in materials and constitutes an even greater challenge densely packed chemically reactive granular systems. Both features are prominently present hydrating pastes composed calcium s...

This study investigated the hydration, rheology, and diffusion resistance of cement pastes involving up to 0.09 wt% graphene oxide (GO) under constant exposure hydrochloric (HCl) acid for four weeks. Samples containing GO revealed a reduction in mass loss sectional area when compared control sample without any GO, highlighting potential inclusion improving matrix attack. While higher dosages re...
