An on-line monitoring method for the flow excitation in francis hydraulic turbine based on dynamics
Authors: Li Zhaojun , Zhang Guangzheng , Liu Fuxiu , Chen Jiaquan 
Published: April 2022

During the operation of hydraulic turbine, the vibration often exceeds the standard due to flow excitation, which affects the safe and stable operation of the hydraulic turbine. In this paper, an on-line monitoring method for the flow excitation in Francis hydraulic turbine is proposed based on the dynamic characteristics of Francis hydraulic turbine. Firstly, based on the flow excitation characteristics in Francis hydraulic turbine and the dynamic equation of main shaft system, the internal relationships between the dynamic response of turbine bearing and the flow excitation in the Francis hydraulic turbine are clarified. Secondly, according to these relationships, a method based on wavelet transform (WT), particle swarm optimization (PSO), and variational mode decomposition (VMD) is proposed for extracting the flow excitation features in Francis hydraulic turbine. Then, by this method, the flow excitation features are acquired. Based on the obtained flow excitation features, the flow excitation can be monitored on-line. Finally, the proposed on-line monitoring method for the flow excitation in Francis hydraulic turbine is verified by experiments. Based on the results, the flow excitation components in the signal extracted by this method are about 35 % more than those extracted by the previous methods. The results show that the on-line monitoring method proposed in this paper is convenient and effective.

Abstract
This study aims to calculate the water balance, interaction with irrigation water inflow, and hydrodynamics of Lake Beseka by a spreadsheet-based model using climatic, hydrological, multi-temporal satellite images, groundwater, and lake chemistry data. The rainfall for the catchment was estimated as 558.4 mm/year, whereas the mean evaporation was computed as 2,214 mm/year by the Penman method. The annual direct rainfall contribution to the lake was found to be 25.84 MCM (million cubic meters) with a runoff inflow in the catchment area of 37.2 MCM. This balance pointed to the mean evaporation of 108.2 MCM/year in the lake indicating that the water inflow was greater than the outflow. A major cause for the rise of the lake level was the drainage of excess irrigation water toward the lake, mainly from the Fentale Irrigation Farm. The average increment of the groundwater level in the area was 12 cm/year from 2010 to 2014. From 1998 to 2014, the electrical conductivity was reduced by 25.6%, and calcium was increased by 96%. The study outlined that appropriate irrigation drainage should be implemented in the catchment to ensure the balance between the rainfall, infiltration, and surface runoff to optimize economic and social welfare in the area.

Published: April 2022

Background:
Background: A combination of antibiotics, including metronidazole (MET), ciprofloxacin
(CIP), and minocycline (MINO), has been demonstrated to disinfect bacteria in necrotic teeth before
regenerative processes. It has been presented clinically that antibiotic pastes may drive to possible stem
cell death, creating difficulties in removing from the canal system, which can limit the regenerative
procedure. This study was designed to (1) synthesize nanofibrous webs containing various concentrations
of different medicaments (triple, double, and calcium hydroxide, Ca(OH)2), and (2) coat the electrospun
fibrous gutta-percha (GP) cones.

Methods:
Poly(vinylpyrrolidone) (PVP)-based electrospun fibrous webs were processed with low medicament
concentrations. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy
(EDX), and X-ray photoelectron spectroscopy (XPS) were carried out to investigate fiber morphology
and antibiotic incorporation, and characterize GP-coated fibrous webs, respectively. The chemical and
physical properties of dentine were determined via fourier transform infrared spectroscopy (FTIR) and
Nano-SEM, respectively. The antimicrobial properties of the different fibrous webs were assessed
against various bacteria by direct nanofiber/bacteria contact. Cytocompatibility was measured by applying
the MTT method.

Results:
The mean fiber diameter of the experimental groups of medicament-containing fibers ranged in
the nm scale and was significantly smaller than PVP fibers. EDX analysis confirmed the presence of
medicaments in the nanofibers. XPS analysis presented a complete coating of the fibers with GPs; FTIR
and Nano-SEM showed no chemical and physical configuration of intracanal medicaments on the dentine
surface. Meanwhile, nanofibrous webs led to a significant reduction in the percentage of viable
bacteria compared to the negative control and PVP.

Conclusion:
Our findings suggest that TA-NFs, DA-NFs, and Ca(OH)2)-NFs coated GP cones have
significant potential in eliminating intracanal bacteria, having cell-friendly behavior and clinical usage
features.
The Association of 25-Hydroxy Vitamin D level with Mean Platelet Volume
in Patients with Acute Coronary Syndrome
Authors: Hajimoradi Behzad , Alirezaei Toktam , Hosseini Behnaz , Pourmotahari Fatemeh 
Published: April 2022

Background and aims:
A better identification of the role of vitamin D in the thrombotic process of acute coronary syndrome (ACS) will help increase the therapeutic options for this important clinical condition. There is little published evidence that 25-hydroxy vitamin D (25(OH)D) serum levels can associate with platelet function and risk of thrombosis.

Materials and Methods:
This prospective study was conducted on 200 patients with a diagnosis of ACS, including patients with unstable angina (UA), non-ST segment elevation myocardial infarction (NSTEMI), and ST segment elevation myocardial infarction (STEMI). In addition to demographics and angiographic data, serum concentrations of 25(OH)D and MPV were recorded in all patients.

Results:
The types of ACS were STEMI (35%), NSTEMI (25%), and UA (40%). The concentrations of 25(OH)D in patients with UA, NSTEMI, and STEMI were 23.53 ± 13.26, 19.25 ± 8.09 and 14.60 ± 8.24 ng/mL respectively (P < 0.001), and the values of MPV were 9.83 ± 1.35, 10.30 ± 1.21, and 11.56 ± 1.38 fL, respectively (P < 0.001).
There was a negative correlation between 25(OH)D and MPV (R = -0.320, P < 0.0001). ROC analysis illustrated a moderate predictive value (AUC 0.706; 95% CI, 0.63–0.72) in identifying the discrimination threshold of MPV (≥ 9.90 fL) for vitamin D deficiency (<20 ng/mL).

Conclusion:
The current study shows an inverse association between MPV and vitamin D levels in ACS patients, especially in the subgroup of STEMI. These findings propose the effect of vitamin D on platelet size and function, suggesting its role in thrombosis and hemostasis, which might explain the link between vitamin D deficiency and cardiovascular diseases.
Video Relay Interpretation and Overcoming Barriers in Health Care for Deaf Users: Scoping Review
Authors: Rivas Velarde Minerva , Jagoe Caroline , Cuculick Jessica 
Published: April 2022

Background
Persons who are deaf are more likely to avoid health care providers than those who can hear, partially because of the lack of means of communication with these providers and the dearth of available interpreters. The use of video remote interpretation, namely the video camera on an electronic device, to connect deaf patients and health providers has rapidly expanded owing to its flexibility and advantageous cost compared with in-person sign language interpretation. Thus, we need to learn more about how this technology could effectively engage with and respond to the priorities of its users.

Objective
We aimed to identify existing evidence regarding the use of video remote interpretation (VRI) in health care settings and to assess whether VRI technology can enable deaf users to overcome barriers to interpretation and improve communication outcomes between them and health care personnel.

Methods
We conducted a search in 7 medical research databases (including MEDLINE, Web of Science, Embase, and Google Scholar) from 2006 including bibliographies and citations of relevant papers. The searches included articles in English, Spanish, and French. The eligibility criteria for study selection included original articles on the use of VRI for deaf or hard of hearing (DHH) sign language users for, or within, health care.

Results
From the original 176 articles identified, 120 were eliminated after reading the article title and abstract, and 41 articles were excluded after they were fully read. In total, 15 articles were included in this study: 4 studies were literature reviews, 4 were surveys, 3 were qualitative studies, and 1 was a mixed methods study that combined qualitative and quantitative data, 1 brief communication, 1 quality improvement report, and 1 secondary analysis. In this scoping review, we identified a knowledge gap regarding the quality of interpretation and training in sign language interpretation for health care. It also shows that this area is underresearched, and evidence is scant. All evidence came from high-income countries, which is particularly problematic given that most DHH persons live in low- and middle-income countries.

Conclusions
Furthering our understanding of the use of VRI technology is pertinent and relevant. The available literature shows that VRI may enable deaf users to overcome interpretation barriers and can potentially improve communication outcomes between them and health personnel within health care services. For VRI to be acceptable, sign language users require a VRI system supported by devices with large screens and a reliable internet connection, as well as qualified interpreters trained on medical interpretation.
DRY SLIDING FRICTION AND WEAR OF THE WC/TIC-CO IN CONTACT WITH AL2O3 FOR TWO SLIDING SPEEDS

Published: April 2022

The paper examines the friction and wear behavior of four different WC/TiC-Co cermets, where three of them are composed of 5%, 10% and 15% TiC additions, and a WC-Co grade without TiC, taken as a reference material for comparison purpose. The principal aim is to improve wear resistance to high sliding speeds (hot rolling) of the WC-Co material as a reference by adding previously-listed percentage of TiC. The samples (cermets) were prepared according to the powder metallurgy procedure, which includes the preparation of the powder mixture, its compression shaping and liquid phase sintering. Sintering was carried out at 1460 ° C, for 14 hours, in a reducing medium (H2). The TiC materials are added in order to boost hardness of the WC-15Co cermet and, consequently, its resistance to wear under thermomechanical conditions. The experiments are conducted using a pin-on-disc tribometer in contact with Al2O3 alumina ball at two sliding speeds of 0.5m/s and 0.75m/s, at a high temperature of 450°C, and a 20 N load. It has been noticed that some recorded friction coefficients are unstable and exhibit many peaks during almost the whole friction test period. The obtained results from the SEM microscope show that the wear behavior of the new proposed material is improved, where it has been shown that, at the sliding speed of 0.75m/s, the greater the TiC percentage is, the lower the average friction coefficient will be. Also, for the speed of 0.5 m/s, the average friction coefficient is relatively more stable with the TiC percentage increase. Moreover, the obtained experimental results show an average wear rate decrease, with respect to reference grades (NA), that amounts to nearly 36% and 41% at the two sliding speeds P1 (0.5m/s) and P2 (0.75m/s), respectively.

Published: April 2022

A adolescência é um período de grandes transformações marcado pelo comportamento sexual de risco, principalmente em consequência do sexo desprotegido. Nesse sentido, o objetivo deste trabalho foi avaliar as atitudes de adolescentes de escolas públicas acerca do uso do preservativo em todas as relações sexuais. Trata-se de um estudo descritivo, transversal, com abordagem quantitativa realizado com 195 adolescentes de escolas públicas da cidade de Caxias, Maranhão. A análise estatística foi realizada por meio do Stata versão 14.0, considerando-se uma significância estatística de P ≤ 0,05. Dos 195 adolescentes que participaram da pesquisa, 55,4% eram do sexo feminino e 54,9% apresentavam idade ≥ 16 anos; 91,3% dos adolescentes apresentaram atitude positiva quanto ao uso do preservativo em todas as relações sexuais; 53,8% já haviam iniciado as relações sexuais, dos quais, 54,3% reportaram o uso do preservativo em todas as relações sexuais. No modelo de regressão logística multinomial, a concepção de que o preservativo diminui o prazer na relação sexual (P = 0,001) e a intenção de fazer sexo mesmo que o(a) parceiro(a) não quisesse usar o preservativo (P = 0,045) foram associados à atitude negativa sobre o uso consistente do preservativo. Apesar do bom conhecimento e atitudes positivas demonstradas pelos adolescentes acerca do uso do preservativo, eles expressam comportamentos sexuais que os tornam vulneráveis ao sexo inseguro, revelando que ainda há forte influência externa sobre suas opiniões e decisões em relação as suas atitudes e práticas sexuais.

Authors: Freitas Taiana Andrade , Rodrigues Érika Dayane Leal , Reis Matheus Moreira 
Published: April 2022

A partir de seu primeiro isolamento em Uganda, em 1937, até os dias de hoje, o vírus do Nilo Ocidental (WNV) tornou-se um alarmante agente etiológico em humanos e animais. O WNV é mantido e perpetuado na natureza através de um ciclo enzoótico, entre aves e mosquitos, e ocasionalmente causa surtos epizoóticos em razão de uma doença contagiosa em humanos e cavalos. Este vírus é amplamente difundido no mundo e, embora grande parte das infecções humanas causadas por WNV seja assintomática, a doença pode evoluir para um quadro neurológico grave, resultando em sequelas a longo prazo ou óbito do paciente. Este estudo tem por objetivo analisar a literatura específica sobre o WNV para apresentar uma revisão de artigos científicos, buscando explorar os aspectos mais importantes da doença. Foram realizadas buscas nas bases de dados PubMed e SciELO a partir dos seguintes descritores: “West Nile virus”, “epidemiology” e “pathogenesi’”. A linha temporal pesquisada abrange de 1998 a 2019, o que permitiu a localização de 293 artigos, dos quais, com base na leitura dos resumos, 88 foram selecionados para realização da leitura completa do artigo. Ao final da leitura dos artigos, 33 foram selecionados na análise final, tendo levado à conclusão de que a vigilância epidemiológica e as medidas preventivas são uma necessidade contínua para reduzir os impactos da doença na saúde pública.
Detecção de listeria monocytogenes em produtos lácteos e produtos cárneos à base de frango
Authors: Drebes Tainá , Adami Fernanda Scherer 
Published: April 2022

Listeria monocytogenes é um patógeno de origem alimentar que frequentemente causa infecções, podendo até ser fatal. Trata-se de um microrganismo ubiquitário, transmitido ao ser humano principalmente por meio dos alimentos, como os produtos prontos para o consumo. O objetivo deste estudo foi verificar os índices de positividade para L. monocytogenes em queijos e produtos cárneos à base de frango, analisados em um laboratório de microbiologia de alimentos do Rio Grande do Sul. A triagem inicial das amostras seguiu o protocolo AOAC, método n° 2004.02, 2004. A confirmação dos resultados positivos foi realizada conforme Instrução Normativa nº 62/2003 (Mapa) e ISO 11290-1:1996, Amd.1:2004. Foram analisadas 666 amostras de queijos de baixa umidade, 3.897 de média umidade e 826 de alta umidade. Dos produtos à base de frango foram analisadas 547 amostras de salsicha, 172 de mortadela e 24 de linguiça. O estudo verificou que os queijos de baixa umidade estão significativamente associados ao resultado positivo (p=0,002) para L. monocytogenes e os queijos de alta umidade associaram-se ao resultado negativo (p=0,002). Com relação aos produtos à base de frango, a salsicha esteve significativamente associada ao resultado negativo para L. monocytogenes (p≤0,01), e a mortadela significativamente associada ao resultado positivo (p≤0,01). Visto que de modo geral esses produtos são consumidos diretamente, sem o emprego de calor, sugere-se reforçar tanto o controle sobre as boas práticas de fabricação quanto o monitoramento dos produtos.

Abstract
In August of 2021, several cysts with juveniles and eggs were discovered during a vegetation survey conducted at the Arlington National Cemetery, Virginia. Eight soil samples were collected from the rhizosphere region of the common grass (Festuca arundinacea L.) and processed at the Mycology and Nematology Genetic Diversity and Biology Laboratory (MNGDBL). Cysts were light to dark brown in color, and oval to pear-shaped without bullae in young cysts but present in older cysts and with prominent vulval cone. The juveniles had slightly concave stylet knobs projecting sometimes anteriorly, tail tapering gradually to a narrowly rounded terminus, and hyaline tail terminus conspicuous at least twice the length of stylet. The molecular analysis included the analysis of three gene sequence fragments: D2–D3 of 28S rRNA, ITS rRNA, and COI. The nematode species was identified by both morphological and molecular means as Stone's cyst nematode, Punctodera stonei. Detection of P. stonei in Virginia represents a new record of this species in the United States, and a second report after Canada in North America.
