Effect of Er, Si, Hf and Nb Additives on the Thermal Stability of Microstructure, Electrical Resistivity and Microhardness of Fine-Grained Aluminum Alloys of Al-0.25%Zr.

The conductor aluminum alloys of Al-0.25wt.%Zr alloyed additionally with X = Er, Si, Hf and Nb were the objects of our investigations.

Investigation of Thermal Stability of Microstructure and Mechanical Properties of Bimetallic Fine-Grained Wires from Al-0.25%Zr-(Sc,Hf) Alloys.

Thermal stability of composite bimetallic wires from five novel microalloyed aluminum alloys with different contents of alloying elements (Zr, Sc, and Hf) is investigated. The alloy workpieces were obtained by induction-casting in a vacuum, preliminary severe plastic deformation, and annealing providing the formation of a uniform microstructure and the nucleation of stabilizing intermetallide Al(Zr,Sc,Hf) nanoparticles. The wires of 0.

Investigation of Effect of Preliminary Annealing on Superplasticity of Ultrafine-Grained Conductor Aluminum Alloys Al-0.5%Mg-Sc.

Effect of preliminary precipitation of AlSc particles on the characteristics of superplastic conductor Al-0.5%Mg-X%Sc (X = 0.2, 0.

[Functional endoscopic sinus surgery in a patient with cystic fibrosis after lung transplantation].

Cystic fibrosis is genetic multisystem disorder with a predominant lesion of the respiratory tract. The duration and quality of life of these patients depends on the state of respiratory function. Progressive lung dysfunction is still the leading cause of mortality patients with cystic fibrosis.

Сhanges in the functional state of the epithelium of the proximal renal tubules in patients with the initial stage of chronic heart failure during simvastatin therapy.

To assess the change in the functional state of the proximal renal tubule epithelium in patients with dyslipidemia on the background of obesity, by determining the concentration in the urine of the examined level of cystatin C and the degree of activity of the renal organ-specific enzymes neutral α-glucosidase (NAG) and L-alaninaminopeptidase (laap) during simvastatin therapy at a daily dose of 20 mg for 6 months. The study involved 88 people who were divided into three groups: control, comparison and main. The control group is a group of practically healthy individuals: 30 people, average age 20.
