Development of the mathematical model of fuel equipment and justification for diagnosing diesel engines by injector needle displacement

This article discusses the proposed method for diagnosing diesel fuel equipment. An analysis of available methods for diagnosing fuel equipment has been carried out. The authors describe their method for diagnosing plunger pairs of a highpressure fuel pump according to the parameter of displacement of the injector needle. The design of the diagnostic device for measuring the movement of the injector needle has been developed and patented. The dependence of the maximum displacement of the injector needle on the increase, due to wear, of the radial clearance of the plunger bushing at the minimum steady state of idling of the engine has been determined. The technique of diagnosing the technical condition of plunger pairs of a high-pressure fuel pump by injector needle displacement is considered in detail

The Use of Bioacoustic Stimulation of the Respiratory System in Complex Medical Rehabilitation at a Health Resort Facility for Patients who have had COVID-associated Pneumonia

BACKGROUND: In the context of the COVID-19 pandemic, the relevance of rehabilitation measures for patients with COVID-associated pneumonia has increased. AIM: The study aimed to review the effect of bioacoustic stimulation of the respiratory system (BSRS) with high-intensity low-frequency sounds on the dynamics of functional indicators of the respiratory system and the cardiovascular system, as well as indicators of psychoemotional and somatic states, the severity of post-traumatic stress disorders (PTSD) and cognitive capabilities in patients who have had COVID-associated pneumonia in the process of their medical rehabilitation at a health resort immediately after treatment of the disease in a hospital. MATERIALS AND METHODS: The randomized controlled open parallel prospective clinical study involved 28 patients undergoing medical rehabilitation after suffering moderate to severe COVID-19 complicated by community-acquired bilateral polysegmental pneumonia (COVID-associated pneumonia) of moderate to severe severity. Spirometry, pulse oximetry, compression oscillometry, bioelectrography, Mississippi Scale (civil version), and cognitive speed test were used to assess the functional parameters of the respiratory and cardiovascular systems, as well as indicators of psychoemotional and somatic states, the intensity of PTSD and cognitive abilities of patients before and after the course of rehabilitation measures. RESULTS: According to significant differences in changes in the indexes of external respiration, cardiac activity, psychological status, and the intensity of PTSD in patients of the main and control groups before and after a course of rehabilitation measures, it has been reliably established that the use of BSRS as a part of a complex of rehabilitation measures significantly increases the effectiveness of medical rehabilitation at a health resort for patients after COVID-associated pneumonia. CONCLUSION: The possibility and feasibility of using medical technology of BSRS with high-intensity low-frequency sound in complex medical rehabilitation of patients after COVID-associated pneumonia at the health resort stage have been scientifically substantiated.</jats:p

Physical and Mechanical Properties of Ti-Zr-Nb Alloys for Medical Use

The work described in this article is aimed at investigating the properties of a group of Ti-Zr-Nb alloys. In modern orthopedics and traumatology, the use of materials for bone implants with a minimum modulus of elasticity is becoming increasingly important. This is due to a number of advantages that allow for better integration of the implants with the bone tissue, including the reduction in the detrimental effect of the load-shielding effect, a better load distribution, and stress distribution, which allows for increasing the life of the implant. It is known that the lowest modulus of elasticity in titanium alloys at normal temperature is achieved by the phase composition consisting of metastable &beta;-phase. It is possible to achieve the desired structure by a combination of alloy composition selection and heat treatment. Quenching of titanium alloys allows for the high-temperature &beta;-phase to be fixed. This paper provides justification of the choice of compositions of the studied alloys by calculation methods. The structure of alloys after melting in a vacuum electric arc furnace in an argon environment was studied. The ingots obtained had a dendritic structure. Homogenizing annealing in a vacuum furnace at 1000 &deg;C for 4 h was used to equalize the composition. The structure of the alloyed sheets after hot rolling and hot rolling and quenching was investigated. The microstructure of the plates in both variants had uniform grains of polyhedral shape. X-ray phase analysis of the plates showed that the content of metastable &beta;-phase was 100% before and after quenching. Microhardness testing of the plates showed no significant effect of quenching. The result of the mechanical properties study showed an increase in the plasticity of the material after quenching, with the tensile plots of the samples after quenching reflecting the area where the reverse phase transition of &beta;&rsquo;&lt;-&gt; &alpha;&rsquo;&rsquo; occurs. Mechanical studies by cyclic loading showed the presence of a superelasticity effect. The Young&rsquo;s modulus study gave a result of 51 GPa for one of the compositions studied. The combination of properties of the materials under investigation has the potential for promising use as a basis for bone implants
