Short Time Correlation Analysis of Melt Pool Behavior in Laser Metal Deposition Using Coaxial Optical Monitoring.

The development and improvement of monitoring and process control systems is one of the important ways of advancing laser metal deposition (LMD). The control of hydrodynamic, heat and mass transfer processes in LMD is extremely important, since these processes directly affect the crystallization of the melt and, accordingly, the microstructural properties and the overall quality of the synthesized part. In this article, the data of coaxial video monitoring of the LMD process were used to assess the features of melt dynamics.

[Hyperbaric oxygenation in the combined treatment of acute kidney failure].

The paper presents the review of the treatment performed in 183 patients with acute renal failure caused by trauma, myorenal syndrome, surgical, obstetric and urological lesions. All the patients underwent hemodialysis. The majority of the patients manifested hypoxia due to pulmonary edema and abnormal central and visceral hemodynamics, anemia resultant from blood loss and suppression of hemopoiesis, impairment of tissue oxidation-reduction enzymes by uremic toxins.

[The characteristics of the clinical picture and treatment of patients with acute kidney failure in obstetrical pathology].

The examination of 45 patients with acute renal failure (ARF) caused by obstetric problems identified 3 types of its clinical course: 1) "pure" ARF; 2) ARF in the presence of sepsis, and 3) ARF in the presence of exogenous intoxication. Types 2 and 3 were more severe and showed higher mortality rates. The average number of hemodialysis sessions per patient was 2.

[Acute kidney failure in surgical patients].

The authors analyze their experience with the treatment of 150 patients with severe acute renal insufficiency. The causes of the acute renal insufficiency were surgical diseases, traumas, operative interventions. Hemodialysis was performed in all the 150 patients in the complex of curative measures.
