AbstractBackground:Obstetric fistula, a debilitating maternal morbidity, occurs in contexts with poor access to and quality of emergency obstetric care, predominantly in sub-Saharan Africa. As many as two million women and girls suffer from fistula, which results in urinary incontinence, vulnerability to stigma for women and families, and economic consequences for the household and the healthcare system. Surgical repair, the gold standard for treatment, remains inaccessible to many and success is not guaranteed. Non-surgical, user-controlled fistula management options are not readily accessible, although some technologies, like insertable devices, have been found to have some level of feasibility and acceptability and provide short-term control over incontinence. As evidence for the effectiveness of tools to support self-management grows, the determinants of their implementation within various contexts remain unknown. The purpose of this qualitative study was to explore with key stakeholders, prior to implementation, those factors that could influence successful implementation of an innovation for self-management of obstetric fistula in a LMIC.Methods:Stakeholders were purposefully identified from sectors that address the needs of women with obstetric fistula in sub-Saharan Africa: clinical care, academia, international health organizations, civil society, and government. Twenty-one key stakeholders were interviewed about their perceptions of innovations for fistula self-management and their implementation. The Consolidated Framework for Implementation Research (CFIR) guided data collection and analysis of transcripts from recorded interviews. Analyses were carried out within Nvivo v.12. Deductive coding focused on constructs within the CFIR, then inductive coding identified additional constructs relevant for implementation.Results:Potential facilitators to implementation included a clear tension for change for low-cost, accessible innovations for self-management and a relative advantage over existing tools. The development of partnerships and identification of champions could also support implementation. Barriers included the lack of evidence identifying the optimal beneficiary and the need for educational strategies that encourage acceptability among clinical providers. Inductive coding revealed an additional relevant construct of sustainability.Conclusions: Effectiveness and implementation of non-surgical tools for fistula self-management should be further examined in LMICs. Future research could inform comprehensive fistula care to reduce vulnerability to stigma and improve quality of life.

Abstract
This work is a study of the nature of neutrinos, which are fundamental building blocks of the universe. Understanding their properties(mass, interaction,...) is vital to piecing together the evolution of the cosmos to the present day and the events leading up to our existence. We obtained the znr ( the redshﬁt at which a neutrino of massmν will become non-relativistic) using neutrino coupled to scalar ﬁeldand relation: znr = ( mν/5.28×10−4ev) −1. We ﬁrst estimate the total of neutrino’s mass Σmυ Using the coupling between the scalar ﬁeldand the neutrinos ,then we obtained znr . Observational data were used in this article are Pantheon and CMB, BAO, CC. We found neutrinos mass is about Σmυ < 0.26(95% conﬁdence level) and znr = 492 for Pantheon catalog and Σmυ < 0.16(95% conﬁdencelevel) and znr = 340 for CMB + BAO + CC + Pantheon .

Abstract
The present research article aims to obtain good weld integrity and avoid material fracture due to high welding temperature. The Computational Fluid Dynamics (CFD) and Finite Element Method (FEM) were used to study GTAW process. The heat source distribution and the convection movement in the melted pool were taking into account. In fact, a two-dimensional (2D) numerical model has been developed for GTAW process and applied for 304L stainless steel. The effects of welding operating parameters were discussed such as voltage and current. The simulation showed that capillary force presented by Marangoni convection affects mainly the weld pool geometry. Therefore, as a result, increasing the welding power and specially the current intensity leads to the growth of the melted zone rapidly, which may induce high residual stress and risks of metal failure. Finally, comparing computed weld profile with the experimental results showed good agreement.

Abstract

A total of 375 un-sexed Japanese quail (Coturnix coturnix japonica) chicks, 5 days-old were randomly allotted to 5 experimental groups to examine the effect of the inclusion of rice gluten meal (RGM) at levels of 2.5 and 5% and supplementation of betaine at levels of 0.5 and 1.0 g/kg diet on the growth performance, carcass characteristics, hematology, serum biochemistry and gastrointestinal tract microbiota of growing Japanese quail under summer season. Quails were fed a basal diet and the other four diets contained 2.5 and 5% RGM with 0.5 or 1.0 g betaine supplementation. The results revealed quails fed 5%RGM + 0.5 or 1.0 g betaine achieved the highest (P < 0.05) body weight at 5 weeks of age, quails fed 5%RGM + 0.5 or 1.0 g betaine recorded the highest (P < 0.05) body weight gain at 1–5 weeks of age. Quails fed 5%RGM + 1.0 g betaine improved (P < 0.05) DFI at all periods. 5%RGM + 0.5 or 1.0 g betaine groups recorded the best FCR at 1–5 weeks of age. RGM and betaine improved CP and EE digestibilities. RGM and betaine was lower (P < 0.05) in abdominal fat. Quails fed 5%RGM + 0.5 or 1.0 g betaine increased (P < 0.05) WBC count. HB level of the quails group fed diet contained 5%RGM + 0.5 or 1.0 g betaine was higher (P < 0.05). Betaine supplementation increased (P < 0.05) the lactic acid bacteria count and decreased (P < 0.05) E-coli and coliform counts. In conclusion, the combination of RGM and betaine could maintain the growth performance, intestinal health and improve nutrients digestibility of Japanese quails during summer season.

Authors: Deivanathan Sarvana Kumar , Prakash J. Thomas Joseph 
Published: September 2022

Abstract
The current study investigated the bio-synthesis of AgNPs (silver nanoparticles) through the use of an extract from the leaves of Rhaphidophora pertusa (R.pertusa). Visual confirmation of the formation of biosynthesized R.pertusasilver nanoparticles (RP-AgNPs) came from observing the colour difference between them. Additionally, it has been examined through FT-IR, HR-SEM, EDAX, XRD, HR-TEM and DLS. At 424 nm the presence of AgNPs has been confirmed by UV-vis spectra. FT-IR reveals the secondary molecules of R.pertusa which are bound with AgNPs contain OH and NH functional groups. The synthesised particles' sizes are validated by HR-TEM which is approximately 19 nm, whereas EDAX investigations have substantiated the existence of AgNPs. The FCC crystallinity of the synthesised RP-AgNPs is confirmed by the XRD report. The size distribution of the particles with a range of 177 nm is discovered using DLS analysis. Significant antioxidant properties are displayed by the bio-synthesised RP-AgNPs for DPPH. Furthermore, it was found that RP-AgNPs are extremely receptive to both thick peptidoglycan and thin peptidoglycan microbes. The MCF-7 cell line is used to test the cytotoxicity of the synthesised RP-AgNPs and the research shows that the MCF-7 cell proliferation is effectively inhibited by the synthesised RP-AgNPs. As a result, the present research findings have enormous potential for the delivery of medication.

Abstract
Background
The incidence of chronic diseases during the COVID-19 pandemic has drastically been reduced worldwide due to disruptions in healthcare systems. The aim of our study is to analyse the trends in the incidence of 7 commonly managed primary care chronic diseases during the last 2 years of the COVID-19 pandemic in Catalonia.
Methods
We performed an observational retrospective population-based study using data from primary care electronic health records from January 2018 to August 2022 (5.1 million people over 14 years). We divided the study period into two: a pre-pandemic period (before 14 March 2020) and a pandemic period. We performed a segmented regression analysis of daily incidence rates per 100,000 inhabitants of 7 chronic diseases: type 2 diabetes mellitus (T2DM), asthma, chronic obstructive pulmonary disease (COPD), ischemic heart disease (IHD), heart failure (HF), hypertension and hypercholesterolemia. In addition, we compared annual incidence between pandemic years (2020, 2021 and 2022) and 2019. Associated incidence rate ratios (IRR) were also calculated. Finally, we estimated the number of expected diagnoses during the pandemic period using data from 2019 and we compared it with the observed data.
Results
We analysed 740,820 new chronic diseases’ diagnoses. Daily incidence rates of all 7 chronic diseases were drastically interrupted on 14 March 2020, and a general upward trend was observed during the following months. Reductions in 2020 were around 30% for all conditions except COPD which had greater reductions (IRR: 0.58 [95% CI: 0.57 to 0.6]) and HF with lesser drops (IRR: 0.86 [95% CI: 0.84 to 0.88]). Some of the chronic conditions have returned to pre-pandemic diagnosis levels, except asthma, COPD and IHD. The return to pre-pandemic diagnosis levels compensated for the drops in 2020 for T2DM and HF, but not for hypertension which presented an incomplete recovery. We also observed an excess of hypercholesterolemia diagnoses of 8.5% (95%CI: 1.81–16.15%).
Conclusions
Although primary care has recovered the pre-pandemic diagnosis levels for some chronic diseases, there are still missing diagnoses of asthma, COPD and IHD that should be addressed.

Published: September 2022

Abstract
Background: Ofloxacin (OFL) is stable and difficult to degrade. It has been detected in water, soil, and plants throughout the world. This study domesticated OFL-contaminated livestock manure soil with simplified carbon sources to identify flora capable of effectively degrading OFL. The changes in the structural composition and diversity of the microbial community and the functional abundance of the soil flora were analyzed by metagenome sequencing technology. The Biolog-ECO microplate method was used to study the utilization of 31 different carbon sources by selected bacteria and to identify the best co-metabolized carbon source for degradation.
Results: Amino acid carbon sources were more likely to cause significant changes in community structures with increasing OFL concentrations during the acclimation stage. The abundance of Sphingobacterium decreased from 69.23% to 9.84%, while Alcaligenes increased from 0.27% to 62.79%, and Stenotrophomonasincreased from 11.63% to 33.33%, becoming the dominant genus. The results suggested that Stenotrophomonas and Alcaligenes were potential candidate bacteria for the degradation of quinolone antibiotics such as OFL. Compared with the first stage of acclimation, there was an 87% increase (the concentration was 30 mg·L-1) in the OFL degradation rate by functional flora obtained by gradient acclimation, and the functional abundance of the microbial community also increased and stabilized with the depth of the domestication process. The most significant changes in membrane transport were observed in the functional abundance of the microbial community, and it was found that itaconic acid, Tween 80, and L-aspartic acid could increase the biomass of the microbial community under OFL stress.
Conclusion: Significant changes in the bacterial composition and functional abundance of the microbial community resulted from the addition of amino acid carbon sources, together with the OFL concentration. Functional flora resulting from domestication were better able to degrade OFL. The addition of a co-metabolic carbon source significantly enhanced the biomass of the functional flora.
Experimental investigation of effective parameters on productivity improvement of the EDM process for corrosion resistant metals

Published: September 2022

Abstract
Inconel 625 superalloy and stainless steel 304 are known for their significant corrosion resistance along with their high hardness and strength. Therefore, they are used in a wide range of industries, including oil and gas, nuclear, etc. Electrical discharge machining is among the most widely used processes for machining of these metals. However, this process has limitations, such as low material removal efficiency, high surface roughness, and the formation of a recast layer. Therefore, in this study, the effective parameters on increasing the material removal efficiency and reducing recast layer thickness are investigated. These parameters include the dielectric fluid, electrode material, discharge current, and pulse duration. After performing the test matrix, the effect of each of the input parameters on the material removal rate, surface roughness and thickness of the recast layer is evaluated using the ANOVA method. The results of this analysis showed that the type of dielectric fluid and the presence of silver oxide nanoparticles have a significant effect on output variables. When using sunflower oil fluid containing nanoparticles and the silver electrode, the recast layer and surface roughness are reduced, while the average material removal rate increases by 40% compared to the traditional mode. Also, due to the biodegradability of deionized water and sunflower oil fluids, the environmental sustainability of the process in this study is increased and while increasing productivity, it leads to the sustainable development of the EDM process.
Assessment of Aortic Arch Morphology for Endovascular Interventions
Authors: TASDEMIR Rabia , CIHAN Omer Faruk , YASIN Sedat 
Published: September 2022

Abstract
Introduction
: The aim of this study was to retrospectively classify the aorta according to the location of the supra-aortic vessels and analyze the aortic arch angle and angulation of supra-aortic branches on Multidetector Computed Tomography (MDCT) images, and contribute relevant data to the literature for use by interventional radiologists, neurologists, and cardiovascular and head-neck surgeons. Our secondary aim was to support the development of the “custom-made” thoracic stent grafts with the help of new data from the current study.
Materials and Methods
A total of 311 images (from 141 females and 170 males) that best suited our purpose were selected through archive screening. After creating three-dimensional reconstructions of the MDCT images, the aortic arch was divided into types according to the location of the brachiocephalic trunk. All images were viewed in the oblique coronal plane, where the angulation of the aortic arch and its branches can be best seen and measurements were obtained. Aortic arch types and angles were examined by age and sex.
Results
When the sex distribution of the aortic arch types was examined, Type 2 aortic arch was more common in males and Type 1 was more common in females. Regarding the age distribution of the aortic arch types, Types 1c and 2d were found only in the 18–44 age group and Types 3a and 3b were only detected in individuals over the age of 65. These findings suggest that aortic arch configuration changes with advancing age. Analysis of the relationship between age and vessel angulation showed only a weak positive correlation between age and aortic arch angle. Aortic arch angle showed a weak negative correlation with the angulation of supra-aortic vessels but a weak positive correlation was found among the angles of supra-aortic branches (p < 0.05; r < 0.4). A significant difference between sexes was observed in terms of the left subclavian artery angle and left common carotid artery angle, which were greater in males than in females (p < 0.05).
Conclusion
Variations in the angulation of the aortic arch and supra-aortic branches may trigger stroke by causing hemodynamic abnormalities. We believe that our findings may help the design of endograft used for endovascular arch repair.
Binder jetting additive manufacturing: spreading and permeation of multiple micron droplets in powder layer
Authors: Hu Ankai , Huang Yanlu , Chen Zhiyi , Li Wei 
Published: September 2022

Abstract
The spread and penetration of binder droplets have a significant impact on the dimensional accuracy and strength of the parts. In this paper, a three-dimensional numerical simulation method for studying the spread and penetration of multiple micron droplets in porous media is proposed and verified by experiments. The results show that the spreading diameter and penetration depth of the binder increase with the number of droplets. However, as the number of droplets increases, the magnitude of their increase decreases. The research results can be used to predict the true spread and penetration state in the Droplet-Powder system and provide help for further understanding the inherent mechanism of photocuring binder spray material increment manufacturing.

Abstract

Medical records are transmitted between medical institutions using cloud-based Electronic Health Record (EHR) systems, which are intended to improve various medical services. Due to the potential of data breaches and the resultant loss of patient data, medical organizations find it challenging to employ cloud-based electronic medical record systems. EHR systems frequently necessitate high transmission costs, energy use, and time loss for physicians and patients. Furthermore, EHR security is a critical concern that jeopardizes patient privacy. Compared to a single system, cloud-based EHR solutions may bring extra security concerns as the system architecture gets more intricate. Access control strategies and the development of efficient security mechanisms for cloud-based EHR data are critical. For privacy reasons, the Dynamic Constrained Message Authentication (DCMA) technique is used in the proposed system to encrypt the outsource medical data by using symmetric key cryptography which uses the Seagull Optimization Algorithm (SOA) for choosing the best random keys for encryption and then resultant data is hashed using the SHA-256 technique. The system is developed in Python language, and the results are assessed using performance metrics including delay time, security rate, false error rate (FER), storage time, retrieval time, throughput ratio, encryption and decryption time, accuracy rate, key generation time, and security. The implemented system is superior in terms of security because it adopts the advance random secret keys generation which adds more security to the system of about 94% with less delay and loss ratio.

Published: September 2022

Abstract
As of currently, a spotless event solar activity precursor technique is being employed to estimate the intensity and onset periods of future 11-year cycles. In the past, it was utilised to make predictions concerning the maximum amplitudes and rising times of cycles ranging from 19 to 24. The reassuring outcomes that have been obtained from all of these iterations can be summarised as follows: In the past, an updated variation of the proposed method was utilised in order to make a prediction concerning the cycle 24's defining parameters. The observed values of spotless events are utilised in the validation of the preliminary forecasts for cycle 24's characteristics. Additionally, the maximum amplitude and ascension period of the 25th solar cycle can be predicted with the assistance of this method. We have made projections on the forthcoming cycle 25 by utilising the stacking LSTM forecasting model. According to the findings of our study, the model that we devised is able to accurately predict both long-term dependencies and trends in the data. The maximum strength of solar cycle 25 will be 47 percent higher than that of cycle 24 thanks to the sunspot amplitude of 171.9 3.4.
