THE PURPOSE. Consider the issues of electricity quality in power supply systems and the results obtained by the authors of the article when monitoring the electrical energy quality in urban electrical networks with a voltage of 0.4 kV. The results of these measurements indicate that at some facilities there are violations of the electricity quality in almost all indicators. Therefore, to ensure proper quality, it is necessary to develop comprehensive measures to maintain power quality indicators within the established limits.METHODS. When solving the problem, methods of comparison and analysis of experimental data were used. RESULTS. We indicate the main problems which inevitably arise when the quality of electrical energy decreases. Present the causes of the electricity low quality. It is shown that in this case there is a violation of the various electrical receivers operation.CONCLUSION. We indicate that earlier investigations of the electrical energy quality mainly considered power supply systems and power receivers of industrial enterprises. We present the examples of poor electricity quality, including in the event of voltage fluctuations. Therefore, when developing measures to maintain the electricity quality within acceptable limits in urban electrical networks, monitoring of electricity quality indicators should be carried out. Only on the basis of its results it is necessary to develop a set of measures to improve the electricity quality. This approach is also expedient because the electricity consumers can potentially order monitoring of the electric energy quality to specialized organizations and, in case of non-compliance with the requirements of GOST 32144-2013, file lawsuits against power supply organizations about violations of the electricity quality with great chances of satisfying them.

<p align="justify">Hail in Pulau Muda Village, Pelalawan Regency, Riau Province, occured on September 23rd 2019 when the entire Riau area was covered by smoke due to forest and land fires phenomenon. The hail was not accompanied by extreme rain and did not cause material harm. However, a study of atmospheric conditions before, during, and after the hail occurred is needed to reference for early warning of future events. The result was analyzed descriptively on the radar products, satellite images and observation parameters. CMAX and VCUT of radar product generated from RainbowV5.9 showed that at 06.02 UTC there was a single CB cloud, which its maximum reflectivity core was 60 dBZ at 5 km height. Both the core reflectivity and its height decreased by the time as the cloud dissipated. Himawari-8 RGB images and cloud top temperature time series processed by SATAID showed a significant decrease of cloud top temperature reached -75<sup>o</sup>C at 06.00 UTC where the cloud had large ice particles with strong updraft and dissipated within 1 hour into thin cirrus and medium-low clouds. ECMWF ERA5 Reanalysis data processed by GrADS showed that surface air temperature, RH, and CAPE index has a different value from h-1 to h+1 of hail occurrence. Vertical profile showed the single CB cloud had much amount of ice particles and also strong updrafts that the maximum value of updraft was 0,202 m/s at the development stage. In contrast, the maximum value of downdraft was 0,032 m/s in the dissipation stage of the cloud.</p>

Purpose
Multisystem inflammatory syndrome that occurs after SARS-Cov-2 infection with fever, cardiogenic shock and hyperinflammation in children, can be life threatening. In this study, it was aimed to investigate the effects of the complaint and duration at diagnosis on the severity of multisystem inflammatory syndrome in children.
Materials and methods
The medical records of 99 pediatric patients, who were diagnosed multisystem inflammatory syndrome between September 2020 and August 2021 according to Centers for Disease Control and Prevention, were evaluated retrospectively. Demographic features, initial findings, and admission time of patients were noted. Patients were categorized according to intensive care necessity.
Results
The median age of the patients was 10 (2-18) and 62 (62.6%) of patients were male. The median duration before admission was 4 (1-10) days. All patients has fever, 81.8% had gastrointestinal and 75.8% had cardiovascular involvement at admission. The patients (56.6%) who were accepted as severe and moderate MIS-C required intensive care. Prolonged fever, delayed admission, cardiovascular involvement, high inflammatory markers, lymphopenia and thrombocytopenia were found to key parameters determining the need for intensive care.
Conclusion
Multisystem inflammatory syndrome in children is a new disease characterized by fever, signs of inflammation and organ dysfunction associated with SARS-CoV-2 infection. Delayed admission, high cardiac and inflammatory markers at diagnosis increase the need for intensive care.
Bezskuteczny upływ terminu z art. 8 § 3 Kodeksu rodzinnego i opiekuńczego a zawarcie małżeństwa konkordatowego
Authors: Jancewicz Zdzisław 
Published: June 2022

Zagadnieniem podjętym w niniejszym publikacji jest wykładnia przepisów o terminie z art. 8 § 3 Kodeks rodzinny i opiekuńczy w kontekście interpretacji art. 10 ustęp 1 punkt 3 Konkordatu. Przeprowadzone badania dowodzą, iż zapisy ustawowe za przesłankę konieczną zawarcia małżeństwa uznają sporządzenie aktu małżeństwa, nie zaś zachowanie pięciodniowego terminu z art. 8 § 3 Kodeksu rodzinnego i opiekuńczego. Pozostają one w zgodzie z zapisami Konkordatu, nawet pomimo jego literalnej wykładni, która może sugerować interpretację odmienną. Należy stwierdzić, że dotychczasowa praktyka orzecznicza, jak i poglądy doktryny mieszczą się w ramach określonych nie tylko ustawą – Kodeks rodzinny i opiekuńczy, ale i przepisami Konkordatu. W konsekwencji bezskuteczny upływ terminu z art. 8 § 3 Kodeksu rodzinnego i opiekuńczego nie będzie miał wpływu na zawarcie małżeństwa konkordatowego, o ile zostanie sporządzony akt małżeństwa (art. 1 § 2 Kodeksu rodzinnego i opiekuńczego).

Published: June 2022

In order to optimally control the marine hybrid power system (HPS) under increasingly complex regulation constraints or hardware constraints, an efficient power-flow scheduling model and optimization algorithm are of great importance. This work focuses on the optimal power-flow scheduling of marine HPS, especially on the efficiency improvement of the penalty functions for satisfying complex constraints. To be specific, an optimal operation model of marine HPS is discussed, and the complex model constraints are described as various penalty functions. Secondly, a novel optimization algorithm, namely adaptive multi-context cooperatively coevolving differential evolution algorithm with random topology and mutated context vector (AMCCDE - rt - mcv) is developed to optimize the aforementioned model. In order to ensure the satisfaction of the complex model constraints, the detailed forms for penalty functions are researched and the optimal parameters for penalty functions are comprehensively compared, analysed and tested by a set of numerical experiments. Finally, the developed methodologies are tested by simulation experiments. Experimental results show that the damping factor, exponent parameter and punish strength constant effect the efficiency of penalty functions a lot, and the developed penalty functions can effectively satisfy all the model constraints with fast response speed. With the integration of penalty functions, the developed methodology can obtain promising performance on the optimal scheduling of the evaluated marine HPS.

Published: June 2022

BACKGROUND: Athletes with chronic ankle pain (CAP) are more inclined to suffer from physical and psychological pain depending on the severity of the injuries, which might trigger the powerless feeling on future sports participation. Therefore, an efficient and simple method is useful to integrate into conventional physiotherapy (CP) for maintaining mental wellness. OBJECTIVE: This research aimed to verify the effects and progress of video-guided deep breathing (DB) integrated into CP through study on the changes of alpha waves and pain scale. METHODS: Alpha waves were recorded using an electroencephalogram (EEG) and a visual analogue scale (VAS) to assess pain intensity before and after the intervention (6 weeks). Thirty CAP participants were recruited and randomly assigned to two groups: group A for video-guided DB integration into their CP and group B for CP. The effects of pre and post intervention were analyzed using a paired t-test with statistical significance set at p< 0.05. RESULTS: Profound results from the research have shown that the participants who received both the DB+CP revealed a significant increase in alpha wave (p< 0.05) at occipital region. CONCLUSION: The significant result reveals an increase in alpha waves in the occipital region after 6 weeks and indicates that the video-guided DB with a smartphone application is able to produce a change in CAP participants. This supports the DB integration to the CP for altering the pain perception.
