The hydration of polar and apolar groups can be explained quantitatively, via the random network model of water, in terms of differential distortions in first hydration shell water-water hydrogen bonding angle. This method of analyzing solute induced structural distortions of water is applied to study the ice-binding type III thermal hysteresis protein. The analysis reveals subtle but significa...

This study concerned the response to freezing of Neurospora crassa conidia in four different states: air-dry, hydrated in water, hydrated in Vogel medium lacking only sucrose, or hydrated in complete Vogel medium. All hydrated conidia were incubated in one of the above media for various times before freezing and were then washed and frozen in distilled water. Viability was estimated by three te...

The dynamic response of the stirred tank reactor (STR) polymer electrolyte membrane (PEM) fuel cell has been explored over the temperature range of 35–105 ◦C. When the fuel cell was operated in the autohumidification mode the fuel cell current “ignited’’ when the membrane water content was greater than a critical level of ∼1.6 H2O/SO3, and it extinguished when the initial membrane water content...

background: despite almost the three decades passed since the chemical attacks of iraqi’s army against the iranian troops, some veterans are still suffering from long-term complications of sulfur mustard (sm) poisoning, including certain skin complaints specially dryness, burning, and pruritus. we thus aimed to evaluate the skin’s water and lipid content in patients with a disability of >25% du...

CONTEXT Currently, the literature on hot yoga is lacking, and there is still much to understand regarding the safety of these practices. However, one point of safety often emphasized is hydration during the practice of hot yoga. AIM The aim of this study was to examine hydration encouragement by hot yoga instructors and hydration behaviors and related outcomes by hot yoga participants. METH...

Partial replacement and co-hydration of calcium aluminate cement (CAC) with ladle slag was investigated in this study as a pathway valorizing the reducing economic cost CAC. The impact on physical microstructural properties were analysed using different techniques such mechanical strength test, freeze-thaw, sulfate attack, XRD, SEM etc. Thermodynamic modelling used to predict phase assemblages ...

BACKGROUND Intravascular volume expansion represents a beneficial measure against contrast-induced acute kidney injury (CI-AKI) in patients undergoing elective angiographic procedures. However, the efficacy of this preventive strategy has not yet been established for patients with ST-elevation-myocardial infarction (STEMI), who are at higher risk of this complication after primary percutaneous ...

We study by means of nuclear magnetic resonance the self-diffusion of protein hydration water at different hydration levels across a large temperature range that includes the deeply supercooled regime. Starting with a single hydration shell (h = 0.3), we consider different hydrations up to h = 0.65. Our experimental evidence indicates that two phenomena play a significant role in the dynamics o...

The rate of hydration influences many important physical properties of gypsum. Previous research examined the rate of gypsum hydration and related this to compressive strength and microstructure development using BET specific surface area analysis. The analysis of gypsum porosity in combination with BET surface area and rate of hydration remains to be done. In the present study, mesoporosity is...

BACKGROUND Hydration in advanced cancer is a controversial area; however, current hydration assessments methods are poorly developed. Bioelectrical impedance vector analysis (BIVA) is an accurate hydration tool; however its application in advanced cancer has not been explored. This study used BIVA to evaluate hydration status in advanced cancer to examine the association of fluid status with sy...
