Implementation of rapid microwave sintering using a 24 GHz gyrotron system.

Rapid microwave sintering of different oxide ceramics with heating rates up to 300 °C/min and zero hold time has been implemented using a 24 GHz gyrotron-based system for high-temperature processing of materials. The design of the system, principle of operation, and process control are described. Particular attention is given to the design of thermal insulation assemblies and the implementation of temperature measurement in an environment with intense electromagnetic fields.

[Preoperative planning of mini-laparotomy in patients with abdominal aortic aneurysms].

Objective: To improve postoperative outcomes in patients with abdominal aortic aneurysms undergoing abdominal aorta replacement via mini-laparotomy by preoperative planning of localization and optimal length of incision.

Material And Methods: There were 40 patients with abdominal aortic aneurysms who underwent abdominal aorta replacement via mini-laparotomy. Preoperative planning of mini-laparotomy was carried out in the main group (=17), empirical mini-laparotomy - in the control group (=23).

Reporting quality of survey research articles published in the pharmacy literature.

Background: Survey research methodology is commonly used in the pharmacy literature and standards have been set forth for quality reporting. A systematic review to assess the reporting quality of survey research has only been completed for general medical literature.

Objectives: The objective of this study is to examine the quality of survey research reporting published in the pharmacy literature and identify reporting areas researchers can focus on for increased transparency in survey research methodology.

On the Mechanism of Microwave Flash Sintering of Ceramics.

The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.
