We report systematic measurements of C v and (∂ P /∂ T ) v in solid hydrogen below 1 K and for orthohydrogen molar concentrations 0.58≥ X ortho ≥0.20. This is the temperature and concentration range associated with a proposed quadrupolar glass phase. The results show no overtly ...
Low-molar-mass LC molecules, owing to their liquid-like structure, lack material integrity and the ability to sustain or exert mechanical stress [18]. To expand the functions and applications of LC molecules, they are transformed into nonvolatile, free-standing polymeric LC systems. For this, ...
For models predicting ΔpCRH between the two visits as the outcome, we included V1 values for gestational age, phthalate metabolites, and cotinine as well as the change in gestational age between the two study visits (weeks). In general, for time varying covariates (gestational weeks and ...
It relates the two specific heat capacities to the universal gas constant (R). What is the difference between Cp=Cv+R and Cp-Cv=R? The equations Cp=Cv+R and Cp-Cv=R are mathematically equivalent and both represent the Mayer's relation. The only difference is that Cp=Cv+...
Currently, the theoretical model of 𝛾∞γ∞ and temperature is derived from the relationship between the activity coefficient and the partial molar excess function, which is expressed as: ln𝛾∞𝑖=Δℎ𝐸,∞𝑖𝑅𝑇−Δ𝑠𝐸,∞𝑖𝑅lnγi∞=ΔhiE,∞RT−ΔsiE,∞R. ...
The specific objectives of this study were: to investigate the relationship between severity of periodontitis and anthropometric measures of adiposity; to identify clusters of subgingival periodontal microorganisms found in obese, overweight, and normal weight periodontitis patients; and to investigate the ...
In addition, it was confirmed that a chitosan sample with moderate molar mass (MW ~100,000) is more convenient to control the viscosity of the spinnable solution. In these conditions, nanofibers made of blend PEO/chitosan have average diameters under dried state between 100 and 150 nm [13]...
