Published: January 2023

IntroductionIn Burkina Faso, the first cases of COVID-19 were reported in March 2020. Health personnel are on the front line of COVID-19 control, and it is important to understand their perceptions and knowledge of the disease. The objective was to determine the knowledge and perceptions of healthcare personnel of COVID-19 in the city of Ouagadougou.MethodThe study was conducted in five plots in the city of Ouagadougou. A total of 20 health workers from public and private health centers in the city of Ouagadougou were selected during May 2020. In-depth individual interviews were conducted, and a thematic analysis was performed using NVIVO.Results and discussionThe routes of transmission identified were promiscuity, respiratory tract, and physical contact. Various symptoms have been noted, such as fever, cough, and runny nose. However, they recognize that these symptoms are not sufficient to make a diagnosis of COVID-19. Similarly, the treatments mentioned are modern medicine and phytomedicine.ConclusionThe research has generated information on healthcare workers' knowledge and perceptions of COVID-19. Therefore, they are useful for decision-making regarding protective measures for health workers in the management of COVID-19.

AimTo explore the predictive value of lymph node ratio (LNR) for the prognosis of medullary thyroid carcinoma (MTC) patients, and constructed prediction models for the 5-year, 10-year and 20-year mortality of MTC patients based on LNR and other predictors.MethodsThis cohort study extracted the data of 2,093 MTC patients aged ≥18 years undergoing total thyroidectomy and neck lymph nodes dissection. Kaplan-Meier curves and log-rank tests were performed to compare survival curves between LNR &lt; 15% group and LNR ≥ 15% group. All data was divided into the training set (n = 1,465) and the testing set (n = 628). The random survival forest model was constructed in the training set and validated in the testing set. The area under the curve (AUC) was employed for evaluating the predictive ability of the model.ResultsThe 5-year, 10-year and 20-year overall survival (OS) and cause-specific survival (CSS) of MTC patients with LNR &lt;15% were higher than those with LNR ≥15%. The OS was 46% and the CSS was 75% after 20 years' follow-up. The AUC of the model for the 5-year, 10-year, and 20-year OS in MTC patients was 0.878 (95%CI: 0.856–0.900), 0.859 (95%CI: 0.838–0.879) and 0.843 (95%CI: 0.823–0.862) in the training set and 0.845 (95%CI: 0.807–0.883), 0.841 (95%CI: 0.807–0.875) and 0.841 (95%CI: 0.811–0.872) in the testing set. In the training set, the AUCs were 0.869 (95%CI: 0.845–0.892), 0.843 (95%CI: 0.821–0.865), 0.819 (95%CI: 0.798–0.840) for the 5-year, 10-year and 20-year CCS in MTC patients, respectively. In the testing set, the AUCs were 0.857 (95%CI: 0.822–0.892), 0.839 (95%CI: 0.805–0.873) and 0.826 (95%CI: 0.794–0.857) for the 5-year CCS, 10-year CCS and 20-year CCS in MTC patients, respectively.ConclusionThe models displayed good predictive performance, which might help identify MTC patients might have poor outcomes and appropriate interventions should be applied in these patients.

IntroductionIt is of great importance to seek agro-industrial byproducts that can serve as unconventional or alternative feedstuffs for poultry, especially those that are substitutive sources of n-3 polyunsaturated fatty acids (PUFAs), as this will contribute to alleviating feed shortage pressure and improving poultry performance and product quality. In this study, the effects of dietary fermented peony seed dreg (FPSD) on the production performance of hens and fatty acid composition of meat and egg yolk were evaluated.MethodsA total of 480 54-week-old Xinyang chickens were divided into 5 groups: control (basal diet); 5% peony seed dreg (PSD); and 5%, 7% and 9% FPSD, and each group consisted of 6 replicates with 16 birds per replicate. Production performances were recorded daily, and egg quality, serum parameters, antibody titers and fatty acid profile in the muscle and yolk were measured at 64 weeks of age.Results and discussionEgg production, feed conversion ratio and egg albumen quality were improved (p &lt; 0.05) by 5% and 7% FPSD groups compared to 5% PSD and the control diet. Immune status was not influenced by PSD, but antibody titres against H7N9 and ND were improved by FPSD diets during most of the experimental periods. Dietary 5% and 7% FPSD increased (p &lt; 0.05) serum high density lipoprotein concentrations and glutathione peroxidase actives. Total n-3 polyunsaturated fatty acids (PUFA) in meat and yolk increased gradually, while the total saturated fatty acids (SFA) and the n-6/n-3 PUFA ratio decreased gradually with increasing dietary FPSD levels. In conclusion, up to 7% dietary FPSD has the potential use to be utilized as a supplement in Xinyang laying hen diets to produce n-3 PUFA-enriched meat and eggs and positively affect production performance and health status.

Enteropathogenic parasites and viruses have been frequently reported in swine and can infect a wide range of mammals, including humans. Among the wide variety of parasites infecting swine, diarrhoeagenic protists are among those that cause significant morbidity. Hepatitis E virus (HEV) has also been reported both in domestic pigs and wild boar and is known to have an important public health significance. These agents share the fecal–oral transmission route, but data on their fecal shedding and circulation pathways are still lacking or incomplete. Hence, the aim of the present study was to characterize the presence of microeukaryotes and HEV in the wild boar of Portugal. Wild boar stool samples (n = 144) were obtained during the official hunting seasons (October to February) in 2018/2019, 2019/2020, and 2021/2022 and tested for Cryptosporidium spp., Balantioides coli, Giardia duodenalis, Blastocystis sp., Enterocytozoon bieneusi and HEV by molecular assays, followed by sequencing and phylogenetic analysis. We have detected Cryptosporidium scrofarum (1.4%, 95% CI: 0.2–4.9), B. coli (14.6%, 95% CI: 9.2–21.4), Blastocystis ST5 (29.2%, 95% CI: 21.9–37.2) and HEV genotype 3 (2.8%, 95% CI: 0.7–6.9; subgenotypes 3e and 3m). Co-infections were observed in thirteen animals where two were positive for both HEV and B. coli, one was positive for both C. scrofarum and Blastocystis ST5, and ten were positive for both B. coli and Blastocystis ST5. Giardia duodenalis and E. bieneusi were not detected in the surveyed wild boar population. As far as we know, this is the first report describing protist infections by Cryptosporidium spp., B. coli, and Blastocystis sp., as well as the first identification of the emerging HEV genotype 3m in wild boar of Portugal. The present work shows that potentially zoonotic protozoa and HEV are circulating in wild boar populations in Portugal. Awareness and epidemic-surveillance network implementation measures targeting wild boar are needed to prevent the spread of these pathogenic agents to humans.

Published: January 2023

The plant Ranunculus acris (L.) is widespread. It is used in folk medicine. The use of herbal medicines can have adverse effects on humans and requires studies of herbal raw materials for genotoxicity. The goals of the study were to examine the toxic and genotoxic effects of aqueous solutions of R. acris flowers at concentrations of 0.625%, 1.25%, 2.5%, 5% and 10% using the Allium test and to determine the numbers of flavonoids and polyphenols and the antioxidant activity of the extracts. It has been shown that aqueous solutions of buttercup flower extract have a depressing effect on mitosis in the cells of the root meristem of Allium cepa (L.) and cause chromosomal abnormalities (chromosomal stickiness, chromosome lagging, nuclear buds and bridges in anaphase).
Long-Term Degradation Evaluation of the Mismatch of Sensitive Capacitance in MEMS Accelerometers

Published: January 2023

During long-term use, MEMS accelerometers will experience degradation, such as bias and scale factor changes. Bias of MEMS capacitive accelerometers usually comes from the mismatch of parasitic capacitance and sensitive capacitance. This paper focuses on the mismatch of sensitive capacitance and analyzes the mechanism of long-term degradation of MEMS accelerometers. Firstly, the effect of sensitive capacitance mismatch on the performance of a MEMS accelerometer was investigated. Secondly, a method of measuring the mismatch of sensitive capacitance was proposed, and the validation experiment shows that the accuracy of this measurement can be less than 1.10×10−5 of the sensitive capacitance. For the samples in this experiment, the measurement error of this method can be less than 0.36 fF. Finally, a high-temperature acceleration experiment was performed. The mismatch of the sensitive capacitance during the experiment was monitored based on the proposed method, and the experimental results are analyzed. The experimental result demonstrates that the mismatch of sensitive capacitance varies linearly with time. The change rates of sensitive capacitance mismatch for the two samples are 2.95×10−7 C0/h and 2.66×10−7 C0/h in the high-temperature acceleration experiment at 145 °C, respectively. The change in sensitive capacitance mismatch seems small, but it is not to be ignored during long-term use. The rate of change is similar for the same batch of samples. This could imply that the adverse effects due to the mismatch of sensitive capacitance changes can be reduced by compensating for this variation.

Entre distinción y precariedad, nuevas territorialidades en el viñedo de Sainte-Foy.
El viñedo de Sainte-Foy- Bordeaux reúne veinte municipios del departamento de la Gironde en un área de apelación que lo aisla de los municipios vecinos del departamento de la Dordogne con los cuales forma desde siempre el « Pays foyen ». Analizando este espacio vitícola, tratamos de entender el tipo de relaciones que han establecido con él los hombres. Evidenciamos que se trata de un espacio de acción, un espacio social, fruto de un paciente esfuerzo de construcción realizado con el tiempo. Los actores contemporáneos tratan de dinamizar nuevamente este edificio para poner de realce la fama de su región y de sus vinos. No queriendo limitarnos a la lectura de la prácticas tanto sociales como espaciales de los actores mayores del viñedo, analizamos también las nuevas prácticas de los obreros agrícolas magrebíes. Estos construyen asi una territorialidad del « pays foyen ». Más globalmente participan a la regeneración de su identidad.

Published: January 2023

Les cartes de potentiel de population de l’Espagne permettent de comprendre le processus de redistribution démographique, soulignant les moments de croissance annuelle cumulée maximale – années 1960 et 1970 ou début du XXIe
siècle – et ceux de stagnation – années 1980 et 1990. Cette cartographie révèle aussi l’importance des processus de métropolisation, avec un dépeuplement de la ville centrale et un accroissement sélectif des couronnes métropolitaines consécutives, puis la reprise de la croissance des grandes villes grâce à l’immigration récente. Au dépeuplement initial des municipalités rurales proches des grandes villes se substitue un accroissement continu qui contraste avec l’affaissement démographique des municipalités rurales éloignées des grands centres urbains. L’étude de cette série de cartes met également en évidence la nouvelle configuration des grands foyers démographiques d’Espagne.

Acoustic properties for Ga–Sn–Zn liquid metal coupler with low melting point and high acoustic impedance
Authors: Ohashi Yuji , Murakami Rikito , Yamaguchi Hiroaki , Yokota Yuui , Yoshikawa Akira 
Published: January 2023

Abstract
Acoustic properties of Ga–Sn–Zn (GSZ) liquid alloy coupler with high acoustic impedance were investigated to evaluate materials with high acoustic impedance. GSZ liquid alloy was prepared and its longitudinal wave velocity and attenuation coefficient were measured using the plane-wave ultrasonic material characterization system. Density of the GSZ liquid alloy was also measured by a constant volume expansion method. The acoustic impedance of the GSZ was 12 times higher than that of the water. Attenuation coefficient of GSZ is much smaller than that of water, exhibiting 7.6 dB mm−1 for water and 0.5 dB mm−1 for GSZ at 200 MHz. Considering the reflection and transmission coefficients at each medium boundary calculated from the experimentally obtained acoustic impedance, it was suggested that the amplitude of the reflected wave from the back surface of the Ir sample can be made about 30 times larger with the GSZ coupler than with the water coupler.
Macro modeling of liquid crystal cell using machine learning method: reservoir computing approach
Authors: Watanabe Makoto , Kotani Kiyoshi , Jimbo Yasuhiko 
Published: January 2023

Abstract
A macro model of liquid crystal cells including electrical and optical behaviors has been developed using a machine learning framework called reservoir computing and implemented into a circuit simulator. Assuming the arbitrary time steps given from the circuit simulator, we confirmed that our model in which the time-continuous reservoir update equation is discretized by a fourth-order Runge–Kutta method shows high prediction accuracy even at the different time steps from that in the training phase. The director distribution of liquid crystals, which is the microscopic state that realizes the specific macroscopic characteristic, capacitance, and transmittance, is not uniquely determined. Therefore, it is essential to utilize the reservoir’s ability to memorize history to improve prediction accuracy. We found it effective to adjust the parameters that control memory length and update speed according to the response time of each capacitance and transmittance.
Raman scattering study on dilute nitride-bismide GaNAsBi alloys: behavior of photo-excited LO phonon-plasmon coupled mode

Published: January 2023

Abstract
We present a Raman scattering study of as-grown and annealed GaAsBi, GaNAs, and GaNAsBi epilayers grown by plasma-assisted molecular beam epitaxy. In particular, photo-excited longitudinal optical phonon-plasmon-coupled (LOPC) modes were investigated using excitation power-dependent measurements. The optical properties of the samples were characterized by photoluminescence and photoreflectance measurements. From Raman scattering, local vibrational modes and disordered activated modes originating from N- and Bi-alloying were confirmed. The strong photo-excited LOPC modes observed in GaAsBi can be attributed to hole trapping caused by the Bi-induced shallow localized states. The weak photo-excited LOPC modes observed in the as-grown GaNAs and GaNAsBi indicate rapid carrier trapping owing to the high defect density in these dilute nitride alloys. After thermal annealing of GaNAs and GaNAsBi, the heavily damped photo-excited LOPC modes were observed, which can be explained by the low electron mobilities related to the N-induced shallow localized states.

Published: January 2023

This research aimed to explore the use of Contemplative Practices (CPs) as a growing teaching pedagogy to cope with the challenges faced by the Higher Education. More specifically, to explore what CPs do the higher education faculty members of Pakistan use in their teaching intentionally or unintentionally. This quantitative survey research presented the findings from a survey outlining six major categories of CPs followed by their sub-practices. Data were collected through Survey Monkey from 502 faculty members of the Master Trainers Faculty Professional Development Program (MT-FPDP). For the analysis of data descriptive statistics (percentage analysis) was used. The results of this study showed that faculty members of Higher Education Institutes (HEIs) did not incorporate stillness, creative, movement, and ritual practices in their teaching. Though, it was found that they use generative and relational practices in their class. They feel more confident and at ease to use practices of dialogues, discussions, perspective sharing, and storytelling. Based on the results of the study researchers recommend that to enable faculty members to use CPs in their class HEC, HEIs, and professional development organizations in Pakistan should plan conferences, training workshops, and seminars with the collaboration of HEIs.

Published: January 2023

Technology has become an important part of nursing students, and its infusion with education is therefore inevitable. This research is one of the few researches that explored the implementation of digital technologies in the context of a Pakistani nursing school. The research in the field of nurse education is scarce with reference to Pakistan and this research aimed to fill the existing gap in the literature. This article aimed to explore the views of nursing students toward the implementation of digital technologies in class. The study applied a qualitative exploratory approach method with the case study as a research design. A purposive sampling technique was applied by selecting Year III and IV students of the nursing programme. The data for this study were collected through students’ focus group discussions, class observations and analysis of students’ online work on the virtual learning environment. The findings indicated that students feel motivated in using different digital tools for their face-to-face classes. However, they also believed that more could be done in handling the issues they faced in using technology for their classes. It is therefore recommended to train teachers well and universities should use their funds for providing high-speed and stable Internet connection to students on campus.
