The microstructure of aluminum-magnesium alloy friction stir weld
Friction stir weld joint of aluminum/magnesium alloy has been structurally characterized after tensile testing. A butt-weld flaw which a surface of joining between two sheets has been revealed. This defect dictates the specificity of sample's fracture in a tensile test
Space anthropomorphous robots application problems
The Space Robotics has two main areas of interest: Orbital Robotics and Planetary Rovers. Orbital Robotics includes manipulation and mobility for scenarios such as International Space Station operations and satellite servicing. Planetary Rovers address scenarios such as Mars and lunar exploration from mobile robot on the surface. Humanoid robots could be useful for future dangerous missions. In this paper reviews tendencies of the development of space robotics, special attention is given to the identification of positive and negative effects of anthropomorphic robots of varying degrees similarity to man. View analysis of robot movement principles. For the main criterion of comparing accepted safety of structure, plants and scientific equipment. The effectiveness of the use of anthropomorphic robots in space is still open. Before making a decision to initiate expensive design space robot is necessary to decide on the establishment of an anthropomorphic or non-anthropomorphic robot by examining all possible factors, because the cost of failure is very high in space.ΠΠΎΡΠΌΠΈΡΠ΅ΡΠΊΠ°Ρ ΡΠΎΠ±ΠΎΡΠΎΡΠ΅Ρ

Introduction. Successful liver transplantation including from donors with a sudden irreversible cardiac arrestΒ requires the use of modern hardware and technical support to maintain, select and sustain organ viability for theΒ period from harvesting to transplantation to the recipient.Materials and methods. Hardware-software systemΒ (HSS) developed by the Russian State Scientific Center for Robotics and Technical Cybernetics (RTC) was usedΒ for testing of normothermic perfusion of donorβs liver ex vivo. The experiment was conducted on the isolatedΒ pig liver (Duroc breed) in accordance with the ethical principles.Result. During perfusion spontaneous recoveryΒ of bile outflow through the cannula installed in the common bile duct (volume of bile released β 240 ml) wasΒ observed, and the color and uniformity of the perfused liver did not differ from the normal parameters. BiochemicalΒ indicators were stabilized at the physiological values after 40 minutes of perfusion procedure.Conclusion.Β Isolated liver transplant was completely restored after 30 minutes of warm ischemia and was functioning wellΒ due to ex vivo perfusion procedure on the new perfusion device. The first case of the new device usage for normothermicΒ liver ex vivo demonstrated hopeful results to be further investigated.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅. Π‘ΠΎΠΊΡΠ°ΡΠ΅Π½ΠΈΠ΅ ΡΠΈΡΠ»Π° ΠΏΠΎΡΠΌΠ΅ΡΡΠ½ΡΡ

Disinfection of Surfaces Contaminated with SARS-CoV-2 Coronavirus by UV Radiation of Low-Pressure Mercury-Vapour Lamp
The aim of the work was to determine the effective ultraviolet (UV) doses required for the disinfection of surfaces contaminated with the SARS-CoV-2 coronavirus using a low-pressure mercury lamp. Materials and methods. To carry out prompt disinfection of surfaces, a specially designed source of UV radiation with a power of 7.5 W at a wavelength of 254 nm in the form of a portable flashlight was employed, which has a high efficiency of UV radiation output and the possibility of long-term autonomous operation from a compact battery. In the studies, a suspension culture of the SARS-CoV-2 coronavirus with biological activity of 5.3β106 PFU/ml was used. The objects of testing were plastic Petri dishes (disposable) and office paper (grade C, density 80 g/m2 ). Results and discussion. Doses of UV radiation that provide disinfection of surfaces contaminated with the COVID-19 pathogen with an efficiency of 99.0 % (paper) to 99.95 % (plastic) have been determined. The results obtained make it possible to recommend a portable UV irradiator for use in the practice of preventive measures to combat the spread of the disease caused by the SARS-CoV-2 coronavirus
Laserforschung. Erarbeitung physikalischer Grundlagen und technischer Konzepte zur On-line Kontrolle und Qualitaetsregelung fuer das Laserschweissen Abschlussbericht
In relationship with the University of St. Petersburg, established as an international co-operation, the scientific and technological basis for a laser welding quality insurance system was worked out. Foundation for this investigation are theoretical models of the static and dynamic behaviour of the melting zone and the keyhole. The reaction of the plasma plume was studied with respect to the influence of the keyhole. The scientific findings created the basis for the on-line process inspection. As part of the investigation, first experience also in the practical implementation of the results were achieved. A prototype, based on the scientific findings, was built up. The innovation of this system is based on multi-sensor technology, in order to detect fast process fluctuations. Especially by measuring the dependencies of angle and dimension of the plasma plume, the variation of the penetration depth was discovered.
