    Условным объектом исследования является магистральный газопровод из стали 13ХФА диаметром 1420 мм и толщиной стенки 25 мм. Целью работы является: разработка рекомендаций по выбору параметров режима и последовательности сварочных операций при ремонте магистральных газопроводов в условиях Крайнего Севера. В процессе исследования проводились расчет параметров режима сварки, прогнозирование химического состава и свойств сварного шва, определение расхода сварочных материалов, анализ вредных и опасных производственных факторов, расчёт экономической эффективности. В результате исследования был произведен подбор оборудования и электродов по полученным результатам, даны рекомендации по снижению вредных и опасных производственных факторов.The conditional object of the study is the main gas pipeline of steel 13HFA with a diameter of 1420 mm and a wall thickness of 25 mm. The purpose of the work is: development of recommendations on the choice of parameters of the regime and sequence of welding operations in the repair of main gas pipelines in the Far North. In the process of the study, the parameters of the welding regime were calculated, the chemical composition and properties of the welded joint were predicted, the consumables consumed, the analysis of harmful and dangerous production factors, and the calculation of economic efficiency. As a result of the research, the selection of equipment and electrodes was made based on the results obtained, recommendations were given to reduce harmful and dangerous production factors

    A COMPARATIVE STUDY FOR NATURAL DEGRADATION OF THREE LOCAL ANESTHETIC DRUGS FOR HUMAN USE BY ¹H NMR RELAXOMETRY AND FT-IR SPECTROSCOPY

    Three anesthetics, lidocaine (xylene), ropivacaine and propofol, with localized area of action while used in human surgery, were investigated by 1H NMR relaxometry and ATR-FT-IR spectroscopy. The injectable liquid anesthetics were then subjected to degradation in natural condition during 36 days by exposure to direct sunlight radiation. The sunlight radiation intensity in the infrared and visible domain as well as UV index was monitored using Adafruit SI1145 breakout board sensor. The temperature and humidity was monitored using a digital DHT11 sensor. The evolution of 1H NMR T2-distributions, IR spectra, pH, refraction index, electric conductivity and total dissolved solids (TDS) show a degradation of studied anesthetics but also in some cases a certain recovery

    ¹H NMR RELAXOMETRY AND ATR-FT-IR SPECTROSOPY USED FOR THE ASSESMENT OF WASTEWATER TREATMENT IN SLAUGHTERHOUSE

    Get PDF
    Advanced 1H NMR relaxometry based on fast Laplace inversion analysis combined with ATR-FT-IR spectroscopy, pH, electric conductivity and TDS (total dissolved solids) measurements were used to assess the purification process for chicken slaughterhouse wastewater. The 1H NMR T2-distribution (able to separate the effect of dissolved pollutants from undissolved pollutants), various integrated areas of IR spectra, the behavior of pH, electric conductivity and TDS show an efficient purification treatment for chemically treated water and evacuated water

    Transverse relaxation time (T2) and 1H spin density ( ) parameter maps were obtained for the pelvis of two women. For that, two anatomical magnetic resonance (MR) images were recorded in axial orientation with a low echo time (TE1 @ 30 ms) and a large echo time (TE @ 200 ms) for a volunteer with normal pelvis and a patient with endometrial cancer. The largest –value was obtained for the right pelvic bones of patient with endometrial cancer and the lowest one was obtained for the uterus of volunteer with normal pelvis

    Safe Parallelism: Compiler Analysis Techniques for Ada and OpenMP

    Get PDF
    There is a growing need to support parallel computation in Ada to cope with the performance requirements of the most advanced functionalities of safety-critical systems. In that regard, the use of parallel programming models is paramount to exploit the benefits of parallelism. Recent works motivate the use of OpenMP for being a de facto standard in high-performance computing for programming shared memory architectures. These works address two important aspects towards the introduction of OpenMP in Ada: the compatibility of the OpenMP syntax with the Ada language, and the interoperability of the OpenMP and the Ada runtimes, demonstrating that OpenMP complements and supports the structured parallelism approach of the tasklet model. This paper addresses a third fundamental aspect: functional safety from a compiler perspective. Particularly, it focuses on race conditions and considers the fine-grain and unstructured capabilities of OpenMP. Hereof, this paper presents a new compiler analysis technique that: (1) identifies potential race conditions in parallel Ada programs based on OpenMP or Ada tasks or both, and (2) provides solutions for the detected races.This work was supported by the Spanish Ministry of Science and Innovation under contract TIN2015-65316-P, and by the FCT (Portuguese Foundation for Science and Technology) within the CISTER Research Unit (CEC/04234).Peer ReviewedPostprint (author's final draft
