Enhanced microstructure and mechanical properties of ZrN-reinforced AlSi10Mg aluminum matrix composite.

Aluminum matrix composites (AMCs), incorporating Zirconium Nitride (ZrN) as reinforcing additives, demonstrate immense promise for applications in aerospace, automotive, and power generation due to their unique combination of low density, superior mechanical properties, and excellent thermal/electrical conductivity. This study explores the influence of ZrN reinforcement on the microstructure and mechanical properties of AlSi10Mg metal-matrix composites. Utilizing high-energy ball milling (HEBM) and spark-plasma sintering (SPS), ZrN/AlSi10Mg composites were synthesized, achieving nearly full density with uniform ZrN distribution, while phase and chemical transformations were not observed in the bulk composites.

[Therapy of asthenoneurotic syndrome in patients with focal muscular dystonia].

Aim: To analyze the prevalence and structure of asthenoneurotic disorders in patients with focal muscular dystonia and determine an effect of the anxiolytic аdaptol (tetramethyltetraazabicyclooctandion) on asthenic syndrome in muscular dystonia.

Material And Methods: Forty patients with focal muscular dystonia were examined. The severity of asthenic syndrome (MFI-20), anxiety (the Hospital scale of anxiety and depression) and depression (the Hamilton Depression Rating Scale) were evaluated.
