Maternity care during COVID-19: a protocol for a qualitative evidence synthesis of women’s and maternity care providers’ views and experiences.

Background: Considerable changes in maternity care provision internationally were implemented in response to COVID-19. Such changes, often occurring suddenly with little advance warning, have had the potential to affect women’s and maternity care providers experience of maternity care, both positively and negatively. For this reason, to gain insight and understanding of personal and professional experiences, we will perform a synthesis of the available qualitative evidence on women and maternity care providers’ views and experiences of maternity care during COVID-19. Methods and analysis: A qualitative evidence synthesis will be conducted. Studies will be eligible if they include pregnant or postpartum women (up to six months) and maternity care providers who received or provided care during COVID-19. To retrieve relevant literature the electronic databases of CINAHL, EMBASE, MEDLINE, PsycINFO, and the Cochrane COVID study register ( https://covid-19.cochrane.org/) will be searched from 01-Jan-2020 to date of search. A combination of search terms based on COVID-19, pregnancy, childbirth and maternity care, and study design, will be used to guide the search. The methodological quality of the included studies will be assessed by at least two reviewers using the Evidence for Policy and Practice Information (EPPI)-Centre 12-criteria quality assessment tool. The Thomas and Harden approach to thematic synthesis will be used for data synthesis. This will involve line by line coding of extracted data, establishing descriptive themes, and determining analytical themes. Confidence in the findings of the review will be assessed by two reviewers independently using Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual). Conclusion: The proposed synthesis of evidence will help identify maternity care needs during a global pandemic from the perspectives of those receiving and providing care. The evidence will inform and help enhance care provision into the future.
Theoretical investigation of acoustic wave velocity of aluminum phosphide under pressure

The bulk and surface acoustic wave velocities of Aluminum phosphide (AlP) semiconducting material under pressure up to 9.5 GPa were studied. The structural parameters and the elastic constants used in this work are taken from our previous paper published in J. Optoelec-tron. Adv. M. 16, 207 (2014). The results obtained at zero-pressure are analyzed and compared with other data of the literature. In addition, the acoustic Grüneisen parameter and the Vickers and Knoop microhardness are predicted and analyzed in detail. Our calculated results are in good agreement with the experimental and other theoretical data of literature.
SuperFish: A Mobile Application for Fish Species Recognition Using Image Processing Techniques and Deep Learning

: People from all around the world face problems in the identification of fish species and users need to have access to scientific expertise to do so and, the situation is not different for Mauritians. Thus, in this project, an innovative smartphone application has been developed for the identification of fish species that are commonly found in the lagoons and coastal areas, including estuaries and the outer reef zones of Mauritius. Our dataset consists of 1520 images with 40 images for each of the 38 fish species that was studied. Eighty-percent of the data was used for training, ten percent was used for validation and the remaining ten percent was used for testing. All the images were first converted to the grayscale format before the application of a Gaussian blur to remove noise. A thresholding operation was then performed on the images in order to subtract the fish from the background. This enabled us to draw a contour around the fish from which several features were extracted. A number of classifiers such as kNN, Support Vector Machines, neural networks, decision trees and random forest were used to find the best performing one. In our case, we found that the kNN algorithm achieved the highest accuracy of 96%. Another model for the recognition was created using the TensorFlow framework which produced an accuracy of 98%. Thus, the results demonstrate the effectiveness of the software in fish identification and in the future, we intend to increase the number of fish species in our dataset and to tackle challenging issues such as partial occlusions and pose variations through the use of more powerful deep learning architectures.

Spontaneous Negative Seroconversion of Both Hepatitis B and C in an Egyptian HD Patient

Background: Hepatitis b virus infection (HBV) was recognized as an important hazard for patients and staff in Hemodialysis Units (HDU), and this issue was first recognized in the 1960s with a set of guidelines for the control of HBV in HDU. HCV is a blood-borne infection and is the most significant cause of viral hepatitis which is mainly transmitted by blood transfusion. Thus, it is reasonable to perform initial screening for HCV in HD patients. Patients admitted or re-admitted to an HD unit are recommended to be tested for HBsAg, HCV, and HIV antibodies and to be followed up monthly or at least every three months after admission to HDU. We aim to present this case of spontaneous clearance of HBV and HCV positive after being positive for more than twelve years on HD. Case Study Megahed et al.; AJMAH, 19(2): 8-14, 2021; Article no.AJMAH. 66317 9 Case Presentation: A 66 years old Egyptian male patient with Chronic Kidney Disease (CKD) from Alexandria had started HD 14 years ago while he tested positive for HCV-Ab and HBs Ag positive, although fared well with normal liver function, while the source of infection was not known. HCV-Ab turned into seronegativity after twelve years on HD. Astonishingly, after 13 years on HD; the test of HBs Ag became negative and hepatitis B surface antibody appears by Elisa testing. This was noticed or observed following the implementation of quality enhancement of the HD parameters in most of the HD services provided units according to the regulations of Ministry of Health (MOH), and this was accompanied by better anemia and more frequent utilization of high flux dialysis with a consequent reduction to the need for blood transfusion in the last four years. Previous publications advocated hypothetical mechanisms of HCV clearance during the process of HD: namely, filtration of the virus particles through the pores of the dialysis membrane and or their adsorption to the HD membrane. These welcome spontaneous clearances of the HBV and HCV in this patient could be attributable to the improvement of anemia state and use of high flux dialysis that might have improved the immunity of this patient. Conclusion: Spontaneous clearance of HBV and HCV could potentially possible and could benefit from the improvement of both patients and HD states that could enhance the immune system or mechanical entrapment of the virus particles. Suggestions need further studies for confirmation.
Effects of supplemental xylanase on in vitro disappearance of dry matter in feed ingredients for swine

Background: Alternative feed ingredients are widely used in swine diets to lower feed costs, but these ingredients contain a large quantity of non-starch polysaccharides. Supplemental xylanase is known to break down non-starch polysaccharides. However, the effects of exogenous xylanase from Bacillus subtilis on various feed ingredients have rarely been compared. Objective: To evaluate the effects of supplemental xylanase on in vitro disappearance of dry matter (DM) in various feed ingredients for pigs. Methods: Nine feed ingredients were used to measure in vitro ileal disappearance and in vitro total tract disappearance of DM. Each ground ingredient was supplemented with either supplemental xylanase (9,000 U/g) or cornstarch at 1.0%. Results: Supplemental xylanase increased in vitro ileal disappearance of DM in wheat, barley, wheat flour, and wheat bran (p<0.05). The in vitro total tract disappearance of DM for barley and wheat bran increased with xylanase addition (p<0.05). Conclusion: Exogenous xylanase could increase in vitro ileal DM disappearance in barley, wheat, wheat flour, and wheat bran, but did not affect in vitro total tract DM disappearance in wheat and wheat flour.
Generalizations of a generalist — common themes among systemic therapies for common cancers

O ncology, along with the rest of medicine, is becoming increasingly subspecialized. Early leaders in the development of medical oncology trained and practiced as generalists, but that generation has been replaced by the current generation of academic oncologists who start specialization early on, often while still in fellowship. Te advantages of being able to concentrate on just one area of oncology, or even just one disease, are obvious in terms of the ability to gain expertise and to advance research. As a result, most of the current literature is written by subspecialists. However, such focused specialization may deprive oncologists of a potentially useful, broader perspective. Indeed, most of medical oncology is still delivered by generalists. An advantage of treating the full spectrum of neoplasms is that one can see common themes that occur across diferent cancers in both tumor behavior and treatment. And a generalist can gain experience with therapies in a variety of diseases, rather than just one. Bevacizumab, imatinib, and everolimus are examples of agents that are used in multiple cancers. So while the trend is to fragment specialties and diseases even further, it may be useful to look in the opposite direction at commonalities that occur across tumor types. I have observed that the dilemmas patients with diferent cancer types face and the discussions I have with them are often quite similar. Although there are exceptions for each of the views below, they often hold true as teaching points, and I have found them particularly useful in instructing fellows.
Measurement of H2O Self-Diffusion Coefficients in Clay Gels by Pulsed-Field-Gradient Nuclear Magnetic Resonance: A Review

Principles of the measurement of the diffusion coefficients by the pulsed-field-gradient (PFG) proton nuclear magnetic resonance (NMR) spectroscopy were reviewed. In the PFG NMR method developed by Stejskal and Tanner, the randomwalk displacement of the target nuclei is encoded as a phase of the spin precession and detected as the decrease in the NMR spin-echo signal intensity with increasing pulsed magnetic field gradients. An example of the measurement of H2O selfdiffusion in water-rich hectorite gels was shown. The obtained diffusion data were explained by a model that free or unbound H2O molecules diffuse in the porous gel by avoiding the randomly placed obstacles (clay platelets sandwiched by bound or immobilized H2O layers). Because nondestructive, quick, high -precision, and three-dimensional measurements of self-diffusion tensors of H2O are possible, PFG NMR is a powerful tool in the clay science.
How many grains are needed for quantifying catchment erosion from
tracer thermochronology?

Abstract. Detrital tracer thermochronology exploits the relationship between bedrock thermochronometric age-elevation profiles and a distribution of detrital grain-ages collected from river, glacial, or other sediment to study spatial changes in the distribution of catchment erosion. If ages increase linearly with elevation, spatially uniform erosion is expected to yield a detrital age distribution that mirrors the catchment's hypsometric curve. Alternatively, a mismatch between detrital and hypsometric distributions may indicate non-uniform erosion within a catchment. For studies seeking to identify the pattern of erosion, measured grain-age populations rarely exceed 100 grains due largely to the time and costs related to individual measurements. With sample sizes of this order, discerning between two detrital age distributions produced by different catchment erosion scenarios can be difficult at a high statistical confidence level. However, there is no established method to quantify the sample-size-dependent uncertainty inherent to detrital tracer thermochronology, and practitioners are often left wondering how many grains is enough? Here, we investigate how sample size affects the uncertainty of detrital age distributions and how such uncertainty affects the ability to uniquely infer the erosional pattern of the upstream area. We do this using the Kolmogorov-Smirnov statistic as metric of dissimilarity among distributions, based on which the statistical confidence of detecting an erosional pattern is determined through Monte Carlo sampling. The techniques are implemented in a new tool (ESD_thermotrace) to consistently report confidence levels as a function of sample size and application-specific variables. The proposed tool is made available as a new open-source Python-based script along with test data. Testing between different hypothesized erosion scenarios with this tool provides thermochronologists with the minimum sample size (i.e. number of bedrock and detrital grain-ages) required to answer their specific scientific question, at their desired level of statistical confidence. Furthermore, in cases of unavoidably small sample size (e.g., due to poor grain quality or low sample volume), we provide a means to calculate the confidence level of interpretations made from the data.
Clinical impacts of the Sudanese anatomical variations in a relation of the recurrent laryngeal nerve to the inferior thyroid artery

Background: Until recently, the knowledge of the anatomical variations in the relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) combined with visual intraoperative RLN identification are essential for the protection of these lifeimportant structures during surgical exposure and the mobilization of thyroid and parathyroid glands. This leads to the proper treatment of patients and improvement of the surgical techniques. Aim: To describe anatomical variations in the relationship of the recurrent laryngeal nerve to the inferior thyroid artery in the Sudanese population. Patients and methods: Following ethical committee approval, an observational descriptive prospective cross-sectional study in the period between March 2019 and February 2020, for anatomical variations in the relation of the recurrent laryngeal nerve to the inferior thyroid artery in seventy-two cervical sides of thirty-six well-dissected embalmed Sudanese cadavers. The RLN was investigated in three positions: posterior to the ITA main trunk, anterior to the ITA main trunk and between the ITA branches. Then, the results were analyzed according to the gender, age and dissection side. Results: We found that the anatomical variations were more frequent in males (97.2%) than females (2.8%). The age of these variations ranged between 31–45 years which represents (61.1%). On the right side of the neck, the commonest position of the RLN is posterior to the ITA (63.9%) followed by in decreasing order of frequency, the RLNs run between the ITA branches (30.6%) and anterior to the ITA (5.6%). On the left side of the neck, the commonest position of the RLN is posterior to the ITA (69.4%). It passed between the ITA branches in (30.6%) of specimens. There was no anterior location of the RLN to the ITA. Variations in a relationship of the RLN to the ITA on one side is significantly different from the opposite side. Conclusions: Although the risk of potential damage to the RLN during surgical neck procedures involving the thyroid gland and parathyroid glands is well recognized, pre-operative detailed surgeon’s knowledge for these frequent anatomical variations and the usage of the ITA as an anatomical landmark for intraoperative RLN recognition is important. This will lead to a reduction of iatrogenic RLN injury prevalence. Future studies are recommended to compare the findings on this cadaveric study with a larger sample size in the long-term period.
Three ways to see in Korean: Sentence final endings, clause structure, and the subjunctive circumstantial evidence construction

An, Duk-Ho. 2020. Three ways to see in Korean: Sentence final endings, clause structure, and the subjunctive circumstantial evidence construction. Linguistic Research 37(3): 477-498. This paper deals with the nature of the lexical item po-ta in Korean. Interestingly, the verb stem po can be used in three different ways: it can be used as a lexical verb meaning ‘to see’; it can be used as an auxiliary whose meaning is similar to ‘to try’; it also has a third use, which expresses the speaker’s uncertainty or conjecture about the truth of the proposition. The gist of the proposal is that in the third construction, which is dubbed the Subjunctive Circumstantial Evidence (SCE) construction, the ending –na, attached to the stem of the main verb, is a subjunctive mood marker, indicating the speaker’s uncertainty, while po is grammaticalized as a kind of evidentiality marker, indicating the speaker’s bias toward the truth of the proposition despite the uncertainty. Based on this, the goal of this paper is to argue that the three different uses of po provide a window into clause structure—especially, the architecture of the right periphery in Korean. The discussion also has implications for the status of sentence final endings in the language. The current analysis is in line with the widely adopted view that there are fine-grained layers of functional projections in the traditional CP domain (Cinque 1999, 2006; Rizzi 1997, among many others).

Model intercomparison of COSMO 5.0 and IFS 45r1 at
kilometer-scale grid spacing

Abstract. The increase in computing power and recent model developments allow the use of global kilometer-scale weather and climate models for routine forecasts. At these scales, deep convective processes can be partially resolved explicitly by the model dynamics. Next to horizontal resolution, other aspects such as the applied numerical methods, the use of the hydrostatic approximation, and timestep size are factors that might influence a model's ability of resolving deep convective processes. In order to improve our understanding of the role of these factors, a model intercomparison between the nonhydrostatic COSMO model and the hydrostatic Integrated Forecast System (IFS) from ECMWF has been conducted. Both models have been run with different spatial and temporal resolutions in order to simulate two summer days over Europe with strong convection. The results are analyzed with focus on vertical wind speed and precipitation. Results show that even at around 3 km horizontal grid spacing the effect of the hydrostatic approximation seems to be negligible. However, timestep proves to be an important factor for deep convective processes, with a reduced timestep generally allowing for higher updraft velocities and thus more energy in vertical velocity spectra, in particular for smaller wavelengths. A shorter timestep is also causing an earlier onset and peak of the diurnal cycle. Furthermore, the amount of horizontal diffusion plays a crucial role for deep convection with more diffusion generally leading to larger convective cells and higher precipitation intensities. The study also shows that for both models the parameterization of deep convection leads to lower updraft and precipitation intensities and biases in the diurnal cycle with a precipitation peak which is too early.
Physics Laboratory Management: A Novel Use of QR Code Tag on Physics Equipment Storage Cabinet

The application of QR codes in laboratory management is an increase, but the study of its use in the physics laboratory equipment storage is rarely done. There are numerous in various laboratory equipment stored in the physics laboratory. Well-organized storage with QR-code installment in the cabinet should be a big consideration to assist laboratory users at trace and emplace the equipment in an appropriate. This study aims to develop the application of QR codes in designing the layout of laboratory equipment at the cabinet. The development of the storage layout of laboratory equipment refers to the research and development methods. There are two main focuses in this study, specifically are how to design the layout storage of laboratory equipment and how to develop the QR code scanning system in a physics laboratory. The questionnaire was distributed to 23 respondents, the highest result with 100% agreement shown when they assessed the utility of a QR code-based laboratory storage system and the design of a laboratory equipment layout. Speaking of the program performance of the QR code-based laboratory-item storage system, about 98% of respondents were satisfied. The laboratory users give a positive response to the laboratory management system that developed based on QR code. They consider the QR code system is an effective way of trace and emplace the laboratory equipment.
