Study on Establishment and Improvement Strategy of Aviation Equipment

As a special commodity with high-tech characteristics required by national development, aviation equipment has the characteristics of confidentiality, long cycle and high risk during the production and research and development. Therefore, the supply chain of its manufacturing and research and development is the focus of national construction and development. On the basis of understanding the current development status of aviation equipment application, this paper analyzes its evaluation system and feedback basic mode through tree vector multiplication and X-0-1 determinant feedback basic mode calculation method, and puts forward corresponding improvement strategies in combination with specific contents, so as to ensure each interest subject to obtain more benefits at the same time. A new management method is proposed for the development of aviation equipment in the future.

Scale control at production wells of Gazpromneft Vostok LLC: Results of field tests and technical and economic assessment of the use of encapsulated inhibitor

At the oil production wells of Gazpromneft Vostok LLC, with the problem of scale formation, there was made an assessment of the possibility of using an encapsulated scale inhibitor. According to the test results, it’s found that the reagent provides effective protection of production wells from salt deposits. There are noted such a positive aspects of this inhibitory protection technology as the absence of corrosive effects on downhole equipment, the possibility of quick organization of well protection, not using metering equipment, independence from the infrastructure and the convenience of loading capsules during workover. A comparative analysis with the classical inhibitor protection with liquid scale inhibitors has been carried out. It is shown that with a water flow rate of up to 38 m3 / day, the use of encapsulated reagents is more cost effective. The limitations of the application of the technology are noted – the difficulty in carrying out additional loading of the reagent into the well without lifting the downhole equipment, application in horizontal and directional wells.

Connectivity as a Design Feature for Industry 4.0 Production Equipment: Application for the Development of an In-Line Metrology System

Industry 4.0 (I4.0) is built upon the capabilities of Internet of Things technologies that facilitate the recollection and processing of data. Originally conceived to improve the performance of manufacturing facilities, the field of application for I4.0 has expanded to reach most industrial sectors. To make the best use of the capabilities of I4.0, machine architectures and design paradigms have had to evolve. This is particularly important as the development of certain advanced manufacturing technologies has been passed from large companies to their subsidiaries and suppliers from around the world. This work discusses how design methodologies, such as those based on functional analysis, can incorporate new functions to enhance the architecture of machines. In particular, the article discusses how connectivity facilitates the development of smart manufacturing capabilities through the incorporation of I4.0 principles and resources that in turn improve the computing capacity available to machine controls and edge devices. These concepts are applied to the development of an in-line metrology station for automotive components. The impact on the design of the machine, particularly on the conception of the control, is analyzed. The resulting machine architecture allows for measurement of critical features of all parts as they are processed at the manufacturing floor, a critical operation in smart factories. Finally, this article discusses how the I4.0 infrastructure can be used to collect and process data to obtain useful information about the process.

Clinical Characteristics and Transmission Routes of COVID-19 in the Early Period of the Pandemic in a Non-Covid Ward of Chest Diseases Hospital

Objective: In the early stages of the outbreak, Covid patients were followed-up in isolated Covid Wards, and the examinations of other pulmonary diseases continued in Non-Covid wards. Differential diagnosis between COVID-19 and infections caused by other pathogens is not adequately recognized. For this reason, it is even more difficult to identify patients who are infected with SARS-CoV2 or other pathogens. In the present study, the clinical characteristics and transmission routes of the Covid-19 cases in Non-Covid Wards within approximately 2 months’ time after the onset of the pandemic were analyzed speculatively. Method: In the early periods of the pandemic, quarantine wards were created for Covid patients in Chest Diseases Hospital, but there were also changes in Non-Covid patients and new Non-Covid hospitalizations. The clinical characteristics and transmission routes of the Covid cases in Non-Covid Ward were examined retrospectively and observationally between 10.03.2020 and 30.04.2020. Results: During this period, a total of 35 Covid cases were detected as a patient, companion and healthcare employees. The median age of the patients was 50 years (min-max 25-85). There were 17 patients (48.6%) who were not severe, and 18 severe patients (51.4%), and 10 (28.6%) patients died. A total of 25 (71,4%) of infected cases were verified with the SARS-CoV-2 Nucleic Acid Test, and 10 (28,6%) were diagnosed clinically and radiologically as possible COVID-19 cases. Being 65 years old or over, having comorbid diseases, especially COPD, the presence of dyspnea as a symptom and involvement on chest radiography were found to be significantly associated with survival (p0.027, 0.009, 0.038, 0.000 and 0.033, respectively). Lymphopenia, increase in neutrophil count, CRP and NLR value were found to be statistically related to survival (p 0.005, 0.001, 0.014 and 0.000, respectively). We found 4 super spreaders, one of whom was a companion, and 3 patients. Conclusion: Potential “super spreaders” can be the source of infection before the quarantine conditions are applied and comprehensive protection is implemented. For this reason, quarantine, use of personal protective equipment, application of social distancing, and the implementation of comprehensive preventive measures, such as disinfection, are crucial in controlling nosocomial infection

Electroencephalogram-based neurofeedback training in persons with stroke: A scoping review in occupational therapy

BACKGROUND: Neurofeedback training targets the relevant brain response under minimal stress. It could be a promising approach for the treatment of patients with brain injury. OBJECTIVE: This review aimed to examine the existing literature to confirm the effectiveness of applied electroencephalogram (EEG)-based neurofeedback training in the area of occupational therapy for upper limb stroke rehabilitation. METHOD: All relevant literature published until July 1, 2020 in five prominent databases (PubMed, CINAHL, PsycINFO, MEDLINE Complete, and Web of Science) was reviewed, based on the five-step review framework proposed by Arksey and O’Malley. RESULTS: After a thorough review, a total of 14 studies were included in this review. Almost studies reported significant improvements as a result of EEG-based neurofeedback training, but this had not always account for the differences in effectiveness between groups. However, the results of these studies suggested that neurofeedback training was effective as compared to the traditional treatment and more effective in combination with EEG than that with simple equipment application. CONCLUSION: This review demonstrated the effectiveness of the combination of occupational therapy and EEG-based neurofeedback training. Most of these treatments are intended for inpatients, but they may be more effective for outpatients, especially if customized to their requirements. Also, such explorations to assess the suitability of the treatment for patient rehabilitation will help reduce barriers to effective interventions. An analysis of the opinions of participants and experts through satisfaction surveys will be helpful.
