Reproductive Women's Knowledge on Possibility of Pregnancy after Birth but before Resumption of Menstruation and Its Associated Factors in Ethiopia: A Population-Based Study Using the 2016 Ethiopian Demographic Health Survey

Introduction Worldwide, specifically in developing countries, women believe that a woman cannot become pregnant unless she sees her first postpartum menstruation. Due to this knowledge gap, most women did not use any contraceptives till their 1st postpartum menstruation. Hence, about 44% of women were susceptible to unintended pregnancy in the postpartum period. Assessing women knowledge on possibility of pregnancy after giving birth but before returning of menses and its associated factors will help to increase women's recognition on the issue and for early commencement of appropriate postpartum family planning methods to reduce burden of unintended pregnancy. Objective To assess the level of knowledge on possibility of pregnancy after giving birth but before returning of menses and its associated factors among reproductive women in Ethiopia. Methods A secondary data analysis using the 2016 Ethiopian Demographic Health Survey was employed. Samples were selected using two-stage stratified sampling technique. Descriptive statistics and logistic regressions were used. Adjusted odds ratio (AOR) with 95% confidence interval was used to interpret associations, and a significant association was declared at a p value of <0.05. Result A total of 15,683 reproductive women aged from 15 to 49 years were included. Of them, about 53% did not know that a woman can get pregnant after giving birth but before resumption of her menstruation. Age being 35 years and above (AOR = 1.50; 95%CI = 1.34, 1.67), educational status of secondary and above (AOR = 1.18; 95%CI = 1.06, 1.32), being ever married (AOR = 1.67; 95%CI = 1.47, 1.89), knowledge of any family planning method (AOR = 1.81; 95%CI = 1.52, 2.16), getting counseling on family planning methods (AOR = 1.41; 95%CI = 1.28, 1.55), and being knowledgeable on their ovulatory cycle (AOR = 1.68; 95%CI = 1.55, 1.82) were found to be significantly associated with being knowledgeable on the issue. Conclusion Reproductive women's level of knowledge on the possibility of pregnancy after giving birth but before returning of menses was low. Factors associated with being knowledgeable on the issue were identified. Therefore, strategies should be developed to increase their level of knowledge for reducing unintended pregnancy and its complications by integrating family planning counseling with infant immunization services.
Sex–Gender Differences in Adult Coeliac Disease at Diagnosis and Gluten-Free-Diet Follow-Up

Coeliac disease (CD) is an immune-mediated enteropathy triggered by gluten ingestion. At CD diagnosis, gender differences have been previously reported, but data regarding follow-up are scant. We investigated gender differences in CD adult patients both at the time of diagnosis and at follow-up after the start of the gluten-free diet (GFD). This is a longitudinal cohort study on adult CD patients diagnosed between 2008 and 2019. Clinical, biochemical, and histological data were assessed and compared between males and females. At diagnosis, female gender was significantly associated with signs of malabsorption (OR 3.39; 95% CI: 1.4–7.9), longer duration of symptoms and/or signs before the diagnosis (OR 3.39; 95% CI: 1.5–7.5), heartburn (OR 2.99; 95% CI: 1.1–8.0), dyspepsia (OR 2.70; 95% CI: 1.1–6.5), nausea/vomit (OR 3.53; 95% CI: 1.1–10.9), and constipation (OR 4.84; 95% CI: 1.2–19.6) and less frequently associated to higher body mass index (OR 0.88; 95% CI: 0.8–0.9) and osteopenia/osteoporosis (OR 0.30; 95% CI: 0.1–0.7) compared to male patients. After 12–30 months, females presented lower median BMI, performed less frequently histological control, and had more frequently anaemia and hypoferritinaemia compared to males. No significant differences concerning the presence of gastrointestinal symptoms, adherence to GFD, and Marsh score were found. Gender differences found at CD diagnosis mostly disappear at the follow-up, showing that these differences can be solved over time.
Effect of Organic Fertilizer Rates on the Water Requirements of Snap Beans (Phaseolus vulgaris L.) plants

A field experiment was carried out during successive autumn seasons of 2019 and 2020 in EL-Kassasien Horticulture Research Station Ismailia Governorate to investigate the effect of water requirements rates (720, 960 and 1200 m 3 / fed) combined with different amounts of organic manure (10, 20, 30 m 3 ) on vegetative growth, chemical composition of plant foliage as well as green pods yield and its quality of snap bean ( Phaseolus vulgaris L . cv. Poulista) grown under sandy soil condition using drip irrigation system. A split plot designed with three replicates was adopted. Irrigation quantities treatments were placed in the main plots and amounts of organic manure treatments were located randomly in the subplots. Results showed that all vegetative growth characteristics, chemical compision characteristics, pods quality and pods yield as well as WUE were significantly increased with increasing rate of applied irrigation water in both seasons. In addition increasing amount of applied irrigation water from 720 to 1200 m 3 /fed. exhibited the highest values of most studied parameters of snap beans plants in both seasons of study. Results show also clearly that studied paremeters were significantly increased with increasing amount of applied organic manure from 10 to 30 m 3 /fed. in both seasons of study. The highest values were obtained with adding highst amounts of organic manure (30 m 3 /Fed.) then irrigate plants by highest rate of water (1200 m 3 /Fed.) and vice versa.
2D Falicov-Kimball Model in the Perturbative Regime at Finite Temperatures

Finite-temperature properties of the Falicov–Kimball model in two approximations were studied in the perturbative regime, i.e. for t/U ? 1, where t = 1 is the hopping constant and U = 10 denotes the Coulomb interaction strength. In our study, we determined the phase diagram of the model in the second order of the perturbation theory, where it reduces to the antiferromagnetic Ising model in the emergent magnetic field. In the fourth order, where our model constitutes the Ising model with more complicated frustrated antiferromagnetic interactions, the phase diagram was established. The Monte Carlo method was employed to investigate the phase transition lines. The existence of stripe ordering at finite temperatures is proved.
Determination of heavy metals including Hg, Pb, Cd, and Cr in edible fishes Liza abu, Brachirus orientalis and attributed cancer and non-cancer risk assessment

Background: Heavy metals are considered as pollutants polluting aquatic ecosystems because of their toxic effects and bioaccumulation in organisms. They can cause chronic poisoning when ingested by human. The present study was conducted to determine the concentration of heavy metals, mercury (Hg), lead (Pb), cadmium (Cd), and chromium (Cr) in the muscle tissue of Liza abu and Brachirus orientalis fish in Mahshahr, and also, to estimate the risk of muscle consumption of these fish. Methods: Forty samples of both fish species were randomly selected and after preparation and extraction and digestion processes, the metals were measured using ICP-OES Agilent Model 5100. Results: The mean concentrations of Hg, Pb, Cd, and Cr in the muscle tissue of the Liza abu fish were 0.616 ± 0.383, 1.227 ± 1.77, 0.076 ± 0.030, and 0.567 ± 0.267 mg/kg dry weight, and in the muscle tissue of the Brachirus orientalis fish were 0.846 ± 0.659, 0.515 ± 1.245, 0.061 ± 0.047, and 0.586 ± 0.548 mg/ kg dry weight, respectively. HI for Liza abu and Brachirus orientalis was 0.025 and 0.336, respectively. Conclusion: According to the results of this study, the concentrations of Hg and Cr in the muscle tissue of Liza abu and Brachirus orientalis were slightly higher than some global standards such as the World Health Organization (WHO) and Food and Agriculture Organization (FAO). HQ index was below 1 for two fish species, meaning that there was no non-carcinogenic risk. In all samples analyzed, carcinogenic risk Cr was slightly above the permissible limit of 1×10-4 to 1×10-6 ،other metals were in this range.
Multiphase CFD Modeling of External Oil Flow From a Journal Bearing

High loads and bearing life requirements make journal bearings a potential choice for use in high power, epicyclic gearboxes in jet engines. Particularly in a planetary configuration the kinematic conditions are complex. With the planet gears rotating about their own axis and orbiting around the sun gear, centrifugal forces generated by both motions interact with each other and affect the external flow behavior of the oil exiting the journal bearing. Computational Fluid Dynamics (CFD) simulations using the Volume of Fluid (VoF) method are carried out in ANSYS Fluent [1] to numerically model the two-phase flow behavior of the oil exiting the bearing and merging into the air surrounding the bearing. This paper presents an investigation of two numerical schemes that are available in ANSYS Fluent to track or capture the air-oil phase interface: the geometric reconstruction scheme and the compressive scheme. Both numerical schemes are used to model the oil outflow behavior in the most simplistic approximation of a journal bearing: a representation, rotating about its own axis, with a circumferentially constant, i.e. concentric, lubricating gap. Based on these simplifications, a three dimensional (3D) CFD sector model with rotationally periodic boundaries is considered. A comparison of the geometric reconstruction scheme and the compressive scheme is presented with regards to the accuracy of the phase interface reconstruction and the time required to reach steady state flow field conditions. The CFD predictions are validated against existing literature data with respect to the flow regime, the direction of the predicted oil flow path and the oil film thickness. Based on the findings and considerations of industrial requirements, a recommendation is made for the most suitable scheme to be used. With a robust and partially validated CFD model in place, the model fidelity can be enhanced to include journal bearing eccentricity. Due to the convergent-divergent gap and the resultant pressure field within the lubricating oil film, the outflow behavior can be expected to be very different compared to that of a concentric journal bearing. Naturally, the inlet boundary conditions for the oil emerging from the journal bearing into the external environment must be consistent with the outlet conditions from the bearing. The second part of this paper therefore focuses on providing a method to generate appropriate inlet boundary conditions for external oil flow from an eccentric journal bearing.
Mechanical Characterization of Ultra-Thin, Flexible Glass Substrates for RF Applications

Glass has been shown to be a capable core substrate material for high-frequency applications. In this article, we examine the capabilities of ultra-thin glass as a material that can be used for high-frequency flexible applications. The two stack-ups discussed in the work presented are 60 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> in total thickness with a core glass substrate (Schott AF32) of 30 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> thickness. One stack-up uses 15 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> JSR GT-N01 as a buildup dielectric on each side of the glass and the other uses 15 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> Taiyo Ink photo imageable dielectric (PID). Both stack-ups have been characterized to 110 GHz and have shown to have comparable performance to materials used in this frequency range. This work then focuses on the mechanical characterization of these stack-ups using free arc bending. The free arc bending tests show that both ultra-thin glass stack-ups are suitable for bending applications as the tested samples can bend to a panel separation below 33% of the sample’s total length. This article concludes that the ultra-thin glass stack-ups are suitable for high-frequency flexible applications because the electrical performance is comparable to other high-frequency rigid materials while exhibiting their flexible capabilities.
Sex-Dependent Regulation of Placental Oleic Acid and Palmitic Acid Metabolism by Maternal Glycemia and Associations with Birthweight

Pregnancy complications such as maternal hyperglycemia increase perinatal mortality and morbidity, but risks are higher in males than in females. We hypothesized that fetal sex-dependent differences in placental palmitic-acid (PA) and oleic-acid (OA) metabolism influence such risks. Placental explants (n = 22) were incubated with isotope-labeled fatty acids (13C-PA or 13C-OA) for 24 or 48 h and the production of forty-seven 13C-PA lipids and thirty-seven 13C-OA lipids quantified by LCMS. Linear regression was used to investigate associations between maternal glycemia, BMI and fetal sex with 13C lipids, and between 13C lipids and birthweight centile. Placental explants from females showed greater incorporation of 13C-OA and 13C-PA into almost all lipids compared to males. Fetal sex also influenced relationships with maternal glycemia, with many 13C-OA and 13C-PA acylcarnitines, 13C-PA-diacylglycerols and 13C-PA phospholipids positively associated with glycemia in females but not in males. In contrast, several 13C-OA triacylglycerols and 13C-OA phospholipids were negatively associated with glycemia in males but not in females. Birthweight centile in females was positively associated with six 13C-PA and three 13C-OA lipids (mainly acylcarnitines) and was negatively associated with eight 13C-OA lipids, while males showed few associations. Fetal sex thus influences placental lipid metabolism and could be a key modulator of the impact of maternal metabolic health on perinatal outcomes, potentially contributing toward sex-specific adaptions in which females prioritize survival.
Accent Anxiety: An Exploration of Non-Native Accent as a Source of Speaking Anxiety among English as a Foreign Language (EFL) Students

Speaking anxiety is a form of foreign language anxiety which may reduce students’ willingness to communicate orally. Despite accent being one of the most salient aspects of speech, there has been little research to date on the relationship between non-native accent and speaking anxiety. The purpose of this study is therefore to examine English learners’ perceptions and beliefs about accent, and also to explore the concept of accent anxiety, that is, speaking anxiety arising due to concern about one’s non-native accent. An anonymous online questionnaire was distributed to English students in a French university. The questionnaire sought to gauge the students’ attitudes both towards speaking and accent and gathered qualitative responses about the students’ experiences of accent anxiety and their coping strategies. A thematic analysis was then carried out on the 54 responses. It was found that the majority of the students did not believe attaining a native-sounding accent was essential to language learning and felt that comprehensibility should be the primary objective. However, many of these students nonetheless considered it a personal goal to sound more native-like. Furthermore, most of the students had at some point in their learning felt embarrassed or worried about their accents, with the two primary causes being fear of negative evaluation from their peers and fear of future communication issues. It was concluded that concern over how non-native accents sound is a potential source of speaking anxiety for learners of English. As these students highlighted the classroom as being the main location where this anxiety arises, the study concludes with some suggestions for educators as well as ideas for future research directions.
Detection of Adverse Cardiac Events in Patients with Acute Myocardial Infarction

Background: Myocardial infarction (MI) has an annual incidence rate of 600 occurrences per 100,000 people and affects over 1.5 million people. This study aimed to assess the major adverse cardiac events (MACE) in patients presenting with acute myocardial infarction (AMI). Patients and methods: A cohort study involved 180 patients with acute myocardial infarction attended to the coronary care unit at Department of Cardiology Zagazig University Hospitals and National Heart Institute. Patients were divided into: Group I: 155 patients with no MACE and Group II: 25 patients with MACE. All patients were subjected to full history taking, clinical examination and laboratory investigation. CHADS-VASc and GRACE scores were performed. Results: The mean age of the current study population was 56.2 (SD 9.9) years, 76.7% of them were males. The mean BMI was 27.9 (SD 3.1) kg/m 2 . About 56.1% of patients were smokers and 45% were hypertensives. CHADs-VASc score of the current study patients was ranging from 0 to 4. The mean GRACE score was 135 (SD 23) ranging from 64 to 187. GRACE score was 0-108 in 12.8%, 109-140 in 50.6% and > 140 in 36.7% of the studied patients. Death occurred in 3.3% of patients. Among the current study patients 2.2%, 2.2%, 3.3% and 3.9% had stroke, stent thrombosis, MI and heart failure, respectively. and GRACE scores are simple and easily calculated scores that provides an additional consideration in predicting of MACE in patients with AMI.
Comparing the performance of UV/Acetylacetone and UV/O3 processes for treatment of olive mill wastewater

Background: Olive mill wastewater (OMW) is characterized by its high organic content and refractory compounds. The aim of this study was to evaluate and compare the efficiency of UV/O3 and UV/ acetylacetone (UV/AcAc) processes for treatment of pretreated OMW by coagulation/microfiltration (C&M) process. Methods: In this study, a laboratory-scale UV plug flow reactor with ancillary equipment was fabricated. The experimental factors including initial pH (5-9), O3 dosages (1.5-4.5 g/h), and AcAc concentrations (0.01-0.03 M) were measured. For both processes, a reaction time of 120 min was considered. The effect of these variables on removal of wastewater contaminants including BOD, COD, TSS, turbidity, phenol, oil, and grease were investigated. Results: Results showed that raw OMW has a high load of pollutants and very low biodegradability (BOD5 /COD=0.12). In UV/O3 process, the optimal conditions were obtained at pH 8 and ozone injection at 4 g/h. The combined C&M-UV/O3 process removed 78.75% COD, 46.66% BOD5 , 90.88% total phenol, 91.78% TSS, 99.14% oil and grease, and 98.38% turbidity, with promotion of BOD5 / COD from 0.12 to 0.33. In UV/AcAc process, the optimal conditions were achieved at pH 5 and AcAc concentration of 0.03 M. The combined C&M-UV/AcAc process removed 58.75% COD, 67.58% BOD5 , 38.03% total phenol, 83.50% TSS, 93.65% oil and grease, and 95.00% turbidity, with promotion of BOD5 / COD from 0.12 to 0.22. Conclusion: The results showed that the UV/O3 process is completely superior to the UV/AcAc process for removal of OMW contaminants, as well as promoting the biodegradability of OMW.
Evaluation of Optical Transport Unit Line-Card Integration in Spatially and Spectrally Flexible Optical Networks in Terms of Device Cost and Network Performance

The explosive growth of internet traffic has accelerated the evolution of optical transport networks, emphasizing the need to expand transmission capacity. To overcome the limitations of conventional single-core/mode fiber-based optical transmission, spatial-division multiplexing (SDM) has been proposed. Spatial and spectral superchannel (Spa & Spe SpCh) technology in SDM-based optical networks realizes high-capacity transmission. Such an optical transmission technology can be supported by the Spa & Spe SpCh transceiver and the reconfigurable optical add/drop multiplexer (ROADM), allocating optical carriers (OCs) in spatial and spectral domains simultaneously. The architectures of the manufactured transceivers and ROADMs installed in advance at each network node are fixed. This necessitates the determination of the appropriate spatial and spectral granularity combination that affects the transceiver and ROADM designs to efficiently utilize the switching capacity and reduce the implementation costs. In this paper, we focus on the performance analysis for the $N$-core MCF-based network deployment issues under different granularity combinations. Detailed evaluation of a 4-core MCF-based network reveals that the device cost and network performance are influenced by spatial and spectral granularities and can provide guidance for real-world network planning and design. In particular, the trade-off between device cost and network performance based on different granularities should be taken into account in network design.
AUDIO-VESTIBULAR EVALUATION IN PATIENTS WITH CERVICOGENIC DIZZINESS

Background: Cervicogenic dizziness has many potential mechanisms and is usually a diagnosis of exclusion. Otoacoustic emissions are used to assess cochlear function. Inner ear disorders commonly affect both cochlea and vestibular labyrinth. Posturography is used to evaluate the incorporation of sensory inputs; visual, vestibular and somatosensory which maintain posture and can be used in patients with cervicogenic dizziness. Objective: Analyze audiological, vestibular and postural findings in patients with spondylo-degenerative changes of the cervical spine with and without dizziness. Patients and Methods: This study was carried out on 70 patients with spondylo-degenerative changes of the cervical spine; 35 associated with dizziness and 35 without dizziness as a control group. Radiological assessment of the cervical spine was done and cervical degenerative index was used to assess severity. Basic audiological evaluation and videonystagmography were done to exclude peripheral and central vestibular lesions. Self-report of dizziness was measured using Dizziness Handicap Inventory. Otoacoustic emissions and posturography were assessed in all patients. Results: CDI total score was significantly higher in patients with dizziness. A positive correlation between CDI score and DHI scores was found. Lower OAES amplitudes were found in the patients with dizziness. SOT scores were lower in dizziness group compared to no-dizziness group. Conclusion: Severity of cervicogenic dizziness could be associated with severity of radiographic findings. Two possible mechanisms may have a role in cervicogenic dizziness include vascular compression mechanism, which was explained by otoacoustic emissions results. Another probable mechanism is neck proprioceptors damage resulting in postural problems in those patients.
