Local overshoot and wind effects on wave overtopping at vertical coastal structures
Authors: De Chowdhury Swapnadip , Zhou Jian G. , Khait Anatoliy , Causon Derek , Qian Ling , Mingham Clive , Pullen Tim
Published: April 2021

Wind effects on wave overtopping over a fully impermeable vertical sea wall were studied numerically using the open-source computational fluid dynamics library OpenFoam. A pressure gradient correction term was incorporated in the momentum equations. In recent studies, it was found that, in the absence of wind, an increase in wave steepness results in a reduction of wave overtopping. This is related to the instability of the standing wave formed at the front of a vertical structure. Such instability was noticed in the range of steepness 0.285–0.443 from previous physical experiments for a regular wave interacting with a vertical structure. The existence of this regime was confirmed in the current study. It was also found that the stability of the standing wave determines the shape and volume of the overshooting jet, which has a strong effect on wave overtopping. When the wind is relatively weak (e.g. a wind speed of 10 m/s) it is unable to alter the overshooting jet very much, meaning a weak wind effect on wave overtopping. When the wind is strong (e.g. a wind speed of 30 m/s) it completely deforms the overshooting jet resulting in overtopping discharge almost three times that without wind.

Significance Statement

Older patients with advanced CKD are at high risk for serious complications and death. Although advance care planning (ACP) is critical to patient-centered care, why such patients seldom discuss ACP with their kidney clinicians is incompletely understood. Data from interviews with 68 patients, care partners, and clinicians in the United States demonstrate they held discordant views about who is responsible for raising ACP and the scope of ACP. Many nephrologists did not view ACP as their responsibility, leaving ACP insufficiently discussed in nephrology clinics, shifting responsibility to patients and primary care providers, and often leading patients to address ACP concerns outside of the medical sphere, if at all. Training nephrologists and clarifying their role in ACP are critical to increasing equitable access to ACP for older patients with CKD.

Background

Older patients with advanced CKD are at high risk for serious complications and death, yet few discuss advance care planning (ACP) with their kidney clinicians. Examining barriers and facilitators to ACP among such patients might help identify patient-centered opportunities for improvement.

Methods

In semistructured interviews in March through August 2019 with purposively sampled patients (aged ≥70 years, CKD stages 4–5, nondialysis), care partners, and clinicians at clinics in across the United States, participants described discussions, factors contributing to ACP completion or avoidance, and perceived value of ACP. We used thematic analysis to analyze data.

Results

We conducted 68 semistructured interviews with 23 patients, 19 care partners, and 26 clinicians. Only seven of 26 (27%) clinicians routinely discussed ACP. About half of the patients had documented ACP, mostly outside the health care system. We found divergent ACP definitions and perspectives; kidney clinicians largely defined ACP as completion of formal documentation, whereas patients viewed it more holistically, wanting discussions about goals, prognosis, and disease trajectory. Clinicians avoided ACP with patients from minority groups, perceiving cultural or religious barriers. Four themes and subthemes informing variation in decisions to discuss ACP and approaches emerged: (1) role ambiguity and responsibility for ACP, (2) questioning the value of ACP, (3) confronting institutional barriers (time, training, reimbursement, and the electronic medical record, EMR), and (4) consequences of avoiding ACP (disparities in ACP access and overconfidence that patients’ wishes are known).

Conclusions

Patients, care partners, and clinicians hold discordant views about the responsibility for discussing ACP and the scope for it. This presents critical barriers to the process, leaving ACP insufficiently discussed with older adults with advanced CKD.
"The Swede from North Dakota": Explicating a Euro-American Folksong
Authors: Leary James P
Published: April 2021

“The Swede from North Dakota,” a narrative folksong or ballad performed in a broken-English “Scandihoovian” dialect, has circulated in differing versions throughout America’s Upper Midwest since the early 1900s. Chronicling the misadventures of an itinerant Swedish farm hand, it has been: performed by vaudevillians, lumberjacks, hobos, labor activists, radio entertainers, and women’s groups; published in newspapers, reminiscences, and songbooks; recorded commercially; repurposed in folksong revivals; and documented yet never studied by folklorists. Fully considered, the song exemplifies ways in which immigrant agrarian and industrial workers simultaneously sustained their respective evolving ethnic/local identities; assimilated elements imposed by larger American institutions; and forged an emergent creolized regional cultural blend by creatively fusing varied Old and New World elements into expressive folk forms.
Accretion formation on the refractory lining during the melting of ferrosilicon
Authors: Nemavhola T.M. , Coetsee T. , Garbers-Craig A.M.
Published: April 2021

Accretions often form in furnaces when slag and charge materials attach to the refractory wall and build up over time. Accretion formation is usually unwanted because it reduces the working volume of the reactor and hinders material flow through the reactor. However, in some instances a thin, stable accretion layer may be desirable to protect the underlying refractory material. In order to prevent and/or manage accretion formation, it is important to understand the underlying principles of this phenomenon in the particular reactor. Excessive accretion formation hampered production at the Exxaro FerroAlloys ferrosilicon melting and atomization plant. This plant uses induction furnaces in which a 15% silicon-iron alloy is produced by batch smelting a mixture of ferrosilicon of 75%Si grade and low-carbon steel. The molten ferrosilicon alloy is then gas-atomized to a powdered product for use as a dense medium in mineral processing plants. The objective of this study was to investigate the effect of different impurity levels in the ferrosilicon feed material on the extent of accretion formation as well as the effect on the accretion properties, which influence the ease of accretion removal upon furnace shut-down. Refractory and accretion samples were collected after a furnace shut-down and characterized using X-ray diffraction and scanning electron microscopy-energy dispersive spectroscopy. It was concluded that the trace elements in the FeSi-75 feed material (Al, Ca, Mn) were mostly responsible for accretion formation, but that rust on the low-carbon steel and oxidation of the steel contributed to accretion attachment to the lining. The total contaminant content, calcium to aluminium ratio in the FeSi-75 feed material, and thereby the liquid to solids ratio in the accretion at temperature determine the strength of attachment as well as growth of the accretion.
A new automated, safe, environmentally sustainable, and high extraction soft-rock underground mining method
Authors: Spearing A.J.S. , Zhang J. , Ma L.
Published: April 2021

Ore deposits are becoming more complex to mine as a result of the exhaustion of surface and other easily mined deposits. There is also increasing socio-political pressure to design more environmentally sound, sustainable, and safe mining practices. Wang and Ma designed a mining method for coal, similar to a modified drift and fill using a continuous miner to take sequential cuts (rooms) that are subsequently backfilled. The authors have modified the concept to make it more autonomous, safer, and less costly using highwall coal mining techniques, modified and adapted for underground applications. The method is more flexible than longwall mining and the percentage extraction would seem to be in the same range. In addition because of the backfilling, surface subsidence would not be a major issue and could be more effectively managed.
Raising awareness globally for women with inherited bleeding disorders: World Federation of Hemophilia Symposium

Published: April 2021

Figures in the World Federation of Hemophilia (WFH) global annual survey indicate, by their absence, that there is under-recognition of bleeding disorders in women. The WFH and its national member organisations (NMOs) are working to raise awareness and improve the diagnosis of care of women with bleeding disorders globally, regionally and locally. WFH initiatives include a global programme focused on improving the diagnosis, care and treatment of women with von Willebrand disease (VWD), and programmes involving education and training in conjunction with NMOs in countries including Honduras and Malaysia. NMOs in Slovakia, Latvia and Sweden describe their local activities. The Slovak Hemophilia Society is in the process of establishing a Women’s Committee and considers peer support and network building as essential tools in addressing the issues faced by women with bleeding disorders. In Latvia, access to resources is difficult and von Willebrand factor is not available. There is concern in the Latvia Hemophilia Society that the fundamental human right of access to healthcare is not being met. It supports WFH initiatives through education and advocacy, and believes that the voices of women with bleeding disorders will be better heard through working together. The Swedish Hemophilia Society’s Women’s Project has worked since 2006 to promote better care for women with bleeding disorders and to raise public awareness. Despite resistance, their campaign to increase the identification of girls and women with VWD, improve diagnosis and care, and raise awareness has been well received by healthcare professionals and has had extensive media coverage.

In order to train specialists in information security (IS), a software and hardware complex “Means of protecting information from leakage through technical channels” has been developed; it provides an opportunity to study the process of information leakage through technical channels and methods of its protection, as well as apply various modules and additional software (software) that clearly demonstrate the features of various methods of information security. The composition of this complex is shown: laboratory stands simulating acoustic, vibroacoustic, acoustoelectric channels and a channel of side electromagnetic radiation and interference. At each of the stands there are information security means (ISMs) that prevent the leakage of confidential information through the corresponding technical channel. To adjust the ISMs for acoustic and vibroacoustic channels, the ISIDORA software has been developed; it allows adjusting the level of the generated acoustic interference to meet the requirements of the security of the room and at the same time to have a comfortable conversation in this room.

Образ города, который конструируется в сознании жителей, — это, с одной стороны, слепок их собственного восприятия объективной реальности, а с другой — результат воздействия сторонних акторов (власти, медиа, лидеров мнений и т.д.). Общественный образ города динамичен, его изучение становится особенно актуальным во время социальных перемен. Цель исследования состоит в определении содержания и структуры образа города (на примере Перми) в общественном сознании. Материалом исследования послужили комментарии подписчиков крупнейших городских сообществ Перми разной направленности: СМИ, общегородские паблики, «Подслушано». Комментарии содержат ключевые слова, связанные с городом и администрацией, и представляют собой ответ на ту медийную городскую повестку, которую выстраивают СМИ и органы власти. Собранный языковой материал подвергается автоматизированной обработке с последующим моделированием образа. Применяемый инструментарий включает программу AntConc и библиотеки для обработки естественного языка на Python. Для моделирования образа города используется комплексная методика, включающая инструменты семантико-когнитивного анализа и корпусной лингвистики. В статье представлены результаты анализа репрезентации общественных образов в городских сообществах Перми.

The paper proposes the implementation of digital filtering using residue number system and the modified truncated multiply and accumulate unit. The work was carried out a theoretical analysis of digital filters using residue number system arithmetic and implemented hardware simulation on FPGA. FPGA hardware simulation results show that the use of residue number system allows to increase the frequency of digital filters up to about 4 times and hardware costs reduce up to 3 times compared to using a common positional number system. The obtained results open up the possibility for efficient hardware implementation of digital filters on modern devices (FPGA, ASIC and etc.) to solve practical problems, such as noise reduction, amplification and suppression of the frequency spectrum, interpolation, decimation, equalization and many others.

Parsing character arrays by recursive scoping and structuring using the example of VRML data. The article presents a new method for structuring, segmentation and algorithmic design of the parser of character arrays using the example of VRML data. The key feature of the method is the ability to form a hierarchically complex object by means of recursive data structuring, which makes it possible to cover in aggregate the entire contents of the object, including its arbitrary nesting of child objects. This leads to high controllability of the development of the parsing algorithm, allowing you to focus each time on a specific piece of data, while not losing sight of the entire aggregate connectivity of information. The results obtained can easily be used in plans for creating convenient data storage structures related to information security, solving the problem of containing the amount of data in files, managing big data in heterogeneous systems, and processing hierarchical data in the Internet of Things.

The aim of this study - assessment of knowledge and awareness of drug addicts on the epidemiology, treatment and prevention of hepatitis B and C infections and AIDS in order to improve preventive measures. In total 64 patients were interviewed: 30 women and 34 men. The method of collecting material: questionnaires, interviews with the help of specially designed questionnaires. The method was based on questionnaire of a public survey conducted by specialists General Department of Federal Service for Execution of Punishment (GUFSIN) in St. Petersburg and Leningrad Region, as well as the Biomedical Center of St. Petersburg in cooperation with Yale University, USA. The age distribution of respondents was uneven. The proportion of young people under the age of 25 years was the lowest - 10.9% of patients, cases aged 25-34 years - 46.8%, 35 years and older ones - 42.2. Such a distribution by age, in general, reflects the age structure of addiction incidence rate in Moscow. The results of the survey patients in the Narcological Clinical Hospital № 17 for the assessment of knowledge on the epidemiology, treatment and prevention of hepatitis B and C, HIV infection and AIDS have shown that they are aware of the epidemiology and treatment of these infections, while women were more knowledgeable than men. At the same time, the respondents showed little knowledge of these issues and little interest in treatment that most likely comes from misunderstanding of risk of these diseases. This ultimately leads to higher values of these patients (not interested in their health and the health of others and underestimating the risk of disease) as a potential sources of infection. When checking the knowledge about the transmission of hepatitis B, C and HIV viruses the highest awareness was observed in respect of HIV infection and AIDS, much less patients know about hepatitis C, and even less - about hepatitis B. Consequently, inadequate awareness (in all aspects of the problems) of the threat posed by the HIV epidemic, AIDS and hepatitis B and C, proves to be another of the many factors contributing to the high incidence of hepatitis and HIV infection among drug addicts. Thus, our results also suggest the importance of sanitation-educational work among the addicted patients and the need for the delivery accessible and fascinating instruction booklet highlighting the key issues of epidemiology, treatment and prevention HIV- infection, hepatitis B and C. Each patient should be provided with a such booklet. It is necessary to develop a test control, allowing to catch the interest and focus on critical issues of prevention and treatment of tuberculosis, HIV infection and parenteral hepatitis, if possible, from time to time to lecture.

The aim of the work was the study of serum from patients with suspected dengue fever by both enzyme immunoassay and immunochromatography. Markers of dengue fever were detected in 6 of 10 travelers returning from Southeast Asia. Analysis of the of immunoglobulin M and G antibody titers ratio (IgG/IgM) showed that the five travelers were infected with dengue fever virus for the first time. At the same moment one of patients was infected with dengue virus repeatedly that is a risk factor for severe complications. Thus, early laboratory diagnosis of dengue based on the detection of NSl=antigen and IgG/IgM ratio has been shown not only to help in making a differential diagnosis, but also in saving the life of the patient, because the dengue fever is characterized by rapid progression to the development of severe complications which are not compatible with life. In cases of fever in travelers which have been coming back from countries where hemorrhagic fever is endemic, we propose to make a differential diagnosis with dengue fever that was confirmed by our study.

The paper considers topical problems in the scientific and methodological provision of epidemiological surveillance of rotavirus infection, such as the significance of different routes of pathogen transmission, a trend in the development of an epidemic process, and mechanisms of its self-regulation. The virological and epidemiological data suggest that the role of rotavirus transmission via water is insignificant (contact transmission is typified by the age-related structure of morbidity; water basins and drinking water show noninfectious viral markers, the resistance of which is much higher than that of the pathogen). A total of 8556patients aged 0 to 14 years with acute enteric infections, who were treated at the Children ’s Infectious Diseases Unit, City Hospital One, Rostov-on-Don, were examined for rotavirus in the period from February 2006 to January 2009. Group A rotaviruses were detected in 34% of the patients. Examination of variations in the trend of rotavirus incidence in children of different ages revealed a set of epidemiological parameters reflecting the dynamics of an epidemic process -phasic development and a change in epidemic infection cycles in the urban population. There was a continuous alternation of epidemic cycles every 2-2.5 months. The developed methods for monitoring the epidemic process make it possible to accurately assess the current epidemiological situation and to predict higher morbidity among infants.

The purpose of the study - to reveal the dependence of the rate of development of liver fibrosis (LF) on genetic factors of hepatitis C virus (HCV) and single nucleotide polymorphisms (SNPs) of the genes of infected people. In the three groups of patients with different rates of development of LF, HCV subtype, viral load, the number of quasi- variant forms and the presence of intergenotype recombinantion, SNPs of human cytokine genes (IL-1ß, IL-6, IL-10, IL-28B, TNF-a , TGF-ß1), hereditary hemochromatosis (HFE), genes involved in the development of endothelial dysfunction (eNOS) and oxidative stress (CYBA) were analyzed. In all groups of patients with HCV subtype 1b prevailed. In the groups with moderate and fast speed of development of LF viral load was revealed to be higher than in the group with the slow development of fibrosis. The number of genetic variants within E2 protein zone in the latter group of patients is characterized to be more than in other groups. Recombinant HCV RNA (2k/1b) was found in the groups with moderate and rapid development of LF. SNP analysis of genes of patients showed a statistically significant relationship between the rapid formation of LF and allelic variants of IL-1ß (-511 TT), IL-10 (-1082 AA), TNF-a (-238 GA or AA) and HFE (S282Y or Y282Y )genes. In other SNPs of analyzed gene there no association with speed of LF was found.
