Vibrational frequencies studied as a function of pressure in phase II of solid benzene

The pressure dependence of the vibrational frequencies of six Raman modes is analyzed in phase II of solid benzene. The frequency shifts 1/nu(partial derivative nu/partial derivative P)(T) of those Raman modes are deduced from this analysis and they are related to the isothermal compressibility kappa(T)= -(1/V)(partial derivative V/partial derivative P)(T) through a constant isothermal mode Gruneisen parameter gamma(T) in phase II of solid benzene. The kappa(T) values predicted here are compared with the kappa(T) obtained from the volumetric measurements in this phase. It is shown here that the isothermal compressibility can be predicted from the vibrational frequencies measured in phase II of solid benzene

Calculation of the T-P Phase Diagrams for the Halogenomethane Compounds (CCl4-nBrn, n=0, 1, 2, 4) Using the Mean Field Theory

The T-P phase diagrams of the halogenomethane compounds (CCl4-nBrn, n = 0, 1, 2, 4) are calculated using a mean field model. By expanding the free energy in terms of the order parameters for the transitions of the liquid (L), rhombohedral (R), face-centered cubic (FCC) and monoclinic (M) phases in those compounds, the phase line equations are derived and they are fitted to the experimental data from the literature. This method of calculating the T-P phase diagram is satisfactory to explain the T-P measurements for the halogenomethane compounds and it can also be applied to two-component systems

physical and pulmonary functions: A case-control study

Aims This study was planned to determine the effects of type 2 diabetes mellitus (DM) and its complications on physical and pulmonary functions.Methods: A total of 110 individuals aged 40-65 years were included in the study, 58 with type 2 DM (study group) and 52 without DM (control group). Physical activity level, functional capacity, pulmonary function, and comorbidity levels were compared between the groups.Results: The mean age of the individuals was 52.42 +/- 5.88 years. Six-minute walk test distance was 507.2 +/- 51.70 m in the study group and 532.23 +/- 50.32 m in the control group (p 0.05), forced expiratory volume in one second (FEV1) (%): 96.78 +/- 14.43 and 99.73 +/- 15.80 (p > 0.05), and FEV1/FVC ratio: 81.97 +/- 4.62 and 80.16 +/- 5.27 (p > 0.05), respectively. The Charlson Comorbidity Index scores of the study and control groups were 1.83 +/- 0.82 and 0.12 +/- 0.32 (p < 0.05).Conclusions: Type 2 DM was associated with lower functional capacity and higher rates of comorbid diseases. Therefore, potential causes of these parameters should be considered in the rehabilitation of type 2 diabetic patients.C1 [Okur, Ismail; Taspinar, Betul; Okur, Eda Ozge] Dumlupinar Univ, Dept Physiotherapy & Rehabil, Kutahya, Turkey.[Telli Atalay, Orcin] Pamukkale Univ, Sch Phys Therapy & Rehabil, Denizli, Turkey.[Pasali Kilit, Turkan] Dumlupinar Univ, Dept Internal Med, Fac Med, Kutahya, Turkey.[Toru Erbay, Umran] Dumlupinar Univ, Dept Chest Dis, Fac Med, Kutahya, Turkey.[Taspinar, Betul] Izmir Democracy Univ, Fac Hlth Sci, Dept Physiotherapy & Rehabil, Izmir, Turkey

lambda-phase transitions in ice Ih near the melting point

This study gives our predictions for the thermal expansivity alpha(p), isothermal compressibility kappa(T), and specific heat Cp near the melting point for ice Ih. We calculate those thermodynamic quantities as functions of temperature and pressure near the melting point using the experimental data for the thermal expansivity as a function of pressure from the literature. The Pippard relations are validated by plotting C-p against alpha(p) and also alpha(p) against kappa(T) linearly close to the melting point in ice Ih. We deduce the values of the slope partial derivative P-m/partial derivative T from those linear plots, which are very close to the experimental value obtained from the P-T phase diagram of ice Ih along the melting curve
