The fitness program involved 30 minutes of circuit-style resistance training 3 days per week. Subjects were prescribed low-fat (30%) isoenergetic diets that consisted of 1200 kcals per day for 1 week (phase 1) and 1600 kcals per day for 9 weeks (phase 2) with HC or higher protein (HP). Fasting blood samples, body composition, anthropometry, resting energy expenditure, and fitness measurements were obtained at 0 and 10 weeks. Subjects were retrospectively stratified into lower (LH) or higher (HH) than 3.5 HOMA groups. Data were analyze...

For a long time, the position of this step was considered independent of the pore size. However, recent experimental studies showed that the pressure of cavitation could depend on the pore size and shape [2]. We hypothesize that the position of cavitation depends on the free energy barrier of formation of the critical nucleus. We show that the nucleation barrier can be estimated by comparing simulated and experimental isotherms. In order to establish a relationship between the cavitation pressure and the pore size, a series of argon and nitrogen adsorption-desorption isotherms were calculated in spherical pores ranging from 5.7 to 9.7 nm, which corresponded to the samples of SBA16 materials explored experimentally. The gauge cell Monte Carlo method was employed to calculate the critical nucleus size and the nucleation barrier [3,4]. The grand canonical Monte Carlo simulation was employed to mimic the spontaneous cavitation process. The simulated isotherms were matched to the experimental data. We found that the nucleation barrier of cavitation increases with the pore size. The nucleation barriers vary from 30 kT to 50 kT in the pores of 5.7nm to 9.7nm. 1. P.I. Ravikovitch and A.V.
