Cardioprotective properties of leptin in patients with excessive body mass [PDF]

open access: yesIrish Journal of Medical Science (1971 -), 2020
Abstract Background Adipose tissue is producing adipokines that play different roles in the pathophysiology of cardiovascular disease. Aims The study aimed to assess the role of selected biomarkers in hypertensive patients with overweight and obesity compared with those with normal body-mass index (BMI).

Effects of A-site nonstoichiometry on oxide ion conduction in 0.94Bi0.5Na0.5TiO3–0.06BaTiO3 ceramics [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Lead free 0.94(Bi0.5Na0.5)TiO3–0.06BaTiO3 ceramics were prepared by conventional solid-state mixed oxide route with the A-site stoichiometry modified to incorporate donor-doping (through Bi-excess) and acceptor-doping (through Na-excess).

Investigations on the preparation of ceramsite from petrochemical excess sludge

open access: yesFrontiers in Chemistry, 2022
Petrochemical excess sludge, as hazardous solid waste, poses a great threat to the environment and is difficult to dispose of in an economic and environmentally friendly way. A new alternative of using the petrochemical excess sludge to prepare ceramsite

Thermodynamic, structural, surface and transport properties of Au-Ni liquid alloy at 1150 K

open access: yesBibechana, 2021
Thermodynamic, structural, surface, and transport properties of Au-Ni liquid alloy at 1150 K were computed using different theoretical approaches. The thermodynamic properties, such as excess Gibbs free energy of mixing, enthalpy of mixing, activity and

Study of the excess property of the L-optimal design for the Laible model

open access: yesVestnik of Saint Petersburg University. Mathematics. Mechanics. Astronomy, 2022
For a rational two-dimensional nonlinear in parameters Laible model used in analytical chemistry, the problem of constructing L-optimal designs is investigated. It is shown that there are two types of optimal designs for this model: saturated (i. e., designs with the number of support points equal to the number of model parameters) and excess (i.

Modelling of volumetric properties of binary and ternary mixtures by CEOS, CEOS/Ge and empirical models [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
Although many cubic equations of state coupled with van der Waals-one fluid mixing rules including temperature dependent interaction parameters are sufficient for representing phase equilibria and excess properties (excess molar enthalpy HE, excess molar

Thermodynamic, structural and surface properties of rare earth metallic alloys: Au-La liquid system

open access: yesBibechana, 2023
A complete information related to the mixing behaviours of Au alloyed with rare earth metals or lanthanides is very scarce. Therefore, an attempt has been made in this work to compute and study the temperature and concentration dependent thermodynamic ...

Excess Thermodynamic Properties and FTIR Studies of Binary Mixtures of Toluene with 2-Propanol or 2-Methyl-1-Propanol

open access: yesMolecules
Physical properties of the binary solutions, toluene with 2-propanol and 2-methyl-1-propanol, were measured at T = 293.15, 298.15, 303.15, 308.15, and 313.15 K and P = 100 kPa. The experimental density values were tested with the Emmerling et al.
