Hydration, Hydration, Hydration [PDF]

open access: yesThe Annals of Occupational Hygiene, 2009
Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at ...

Effects of the NaCl Concentration and Montmorillonite Content on Formation Kinetics of Methane Hydrate

open access: yesJournal of Marine Science and Engineering, 2022
Most resources of natural gas hydrate (NGH) exist in marine sediments where salts and sea mud are involved. It is of great importance to investigate the effects of salts and sea mud on NGH formation kinetics. In this study, the mixture of silica sand and

Improved Formation Kinetics of Carbon Dioxide Hydrate in Brine Induced by Sodium Dodecyl Sulfate

open access: yesEnergies, 2021
Due to high efficiency and low cost, hydrate-based desalination is investigated as a pretreatment method for seawater desalination. To improve the formation rate of hydrates, the effect of sodium dodecyl sulfate (SDS) on CO2 hydrate formation from a 3.5 ...

Nutrition and Hydration

open access: yes, 2023
AbstractNutrition and hydration are fundamental aspects of healthcare, especially in the care of older people, particularly those in hospitals or in long-term care facilities. Worldwide, nurses are ‘best-placed’ coordinators of interdisciplinary nutritional management and care processes.

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]

open access: yes, 2009
Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in

Effects of Salinity on Formation Behavior of Methane Hydrate in Montmorillonite

open access: yesEnergies, 2020
In marine sediments, seawater influences the phase behavior of natural gas hydrate. As a porous medium, the water distribution and physical properties of montmorillonite are influenced by the salt ions in seawater.
