Application of Recursive Theory of Slow Viscoelastic Flow to the Hydrodynamics of Second-Order Fluid Flowing through a Uniformly Porous Circular Tube

Slow velocity fluid flow problems in small diameter channels have many important applications in science and industry. Many researchers have modeled the flow through renal tubule, hollow fiber dialyzer and flat plate dialyzer using Navier Stokes equations with suitable simplifying assumptions and boundary conditions. The aim of this article is to investigate the hydrodynamical aspects of steady, axisymmetric and slow flow of a general second-order Rivlin-Ericksen fluid in a porous-walled circular tube with constant wall permeability. The governing compatibility equation have been derived and solved analytically for the stream function by applying Langlois recursive approach for slow viscoelastic flows. Analytical expressions for velocity components, pressure, volume flow rate, fractional reabsorption, wall shear stress and stream function have been obtained correct to third order. The effects of wall Reynolds number and certain non-Newtonian parameters have been studied and presented graphically. The obtained analytical expressions are in agreement with the existing solutions in literature if non-Newtonian parameters approach to zero. The solutions obtained in this article may be considered as a generalization to the existing work. The results indicate that there is a significant dependence of the flow variables on the wall Reynolds number and non-Newtonian parameters.
Changes of Cardiac Rhythm after Closure of Secundum Atrial Septal Defect in Children

Background: Arrhythmias may complicate congenital heart diseases, such as secundum atrial septal defects. We aimed at following up the rhythm changes in children after closure of ostiumsecundum atrial septal defects. Methods: The current study was conducted in the Pediatric Cardiology Unit, Tanta University, on 60 pediatric patients who had undergone either trans-catheter or surgical closure of secundum atrial septal defects. Complete history taking and full clinical assessment were done. Echocardiographic assessment was performed to detect any residual defects, and assess chamber dimensions, and cardiac functions. Electrocardiographic assessment including Holter monitoring was performed within two months after the procedure, after six months, and after one year. Arrhythmias were classified into major and minor types. All results were statistically analyzed and tabulated. Results: There were no significant differences between the pre-closure rhythm and the rhythm after closure of the defects throughout the follow-up. The percentage of patients with major arrhythmias Original Research Article Sorour et al.; JAMMR, 32(10): 84-96, 2020; Article no.JAMMR. 58832 85 has increased from 6.7% of the total sample to 13.3%, 11.6%, and 11.6% in the early, midterm and late follow up respectively. The significant risk factors for postoperative arrhythmias were; pre-closure arrhythmia, right atrial dilatation, and serious hemodynamic instability in the early follow up. Conclusions: We concluded that arrhythmias were common before and after atrial septal defect closure, without significant differences. Pre-closure arrhythmia, right atrial dilatation, and serious hemodynamic instability are considered important risk factors of arrhythmias after secundum atrial septal defect’s closure in pediatric patients.
Authoritarianism, Prejudice, and Support for Welfare Chauvinism in the United States

Abstract This article examines the role of authoritarianism in shaping individual policy support for creating a waiting period before legal immigrants can access welfare programs. I use logistic regression models to analyse the opinions of non-Latino whites from the 1992 American National Election Study (ANES). I find that authoritarianism is related to a waiting period before immigrants can access welfare benefits, despite a significant number of non-authoritarians also preferring a waiting period. This effect is robust with the inclusion of several traditional predictors of welfare attitudes.
Examination of the links between functions of aggression and risk for e-cigarette use among middle school-age youth: a comparison with risk for alcohol use

ABSTRACT Background: Extant literature suggests that associations between aggression and substance use differ based on proactive and reactive functions of aggression and the specific substance use outcomes examined. To date, no research has examined links between these functions of aggression and e-cigarette use specifically, which could aid in developing prevention and intervention efforts of this substance that is gaining popularity among youth. Methods: The current study examines associations between youth reports of proactive and reactive aggression and lifetime e-cigarette use in a sample of middle school-age youth, during a developmental time in which risk for e-cigarette use increases. Results: Findings suggested that while both proactive and reactive aggression are associated with lifetime e-cigarette use, reactive aggression is more robustly linked to e-cigarette use (as well as lifetime alcohol use) than proactive aggression. Further, these associations were not moderated by youth perceptions of parental approval of e-cigarette use. Conclusions: Reactive aggression appears to be most strongly associated with e-cigarette use in middle school. Findings and their implications are further discussed.
Load Centralization Does Not Affect the Kinetic and Kinematic Output of Countermovement Jumps

Abstract Tredrea, MSJ, Middleton, KJ, Bourne, MN, Carey, DL, Scanlan, AT, and Dascombe, BJ. Load centralization does not affect the kinetic and kinematic output of countermovement jumps. J Strength Cond Res 36(4): 1084–1089, 2022—This study aimed to compare the kinetics, kinematics, and performance of countermovement jumps (CMJs) when completed with 2 different loading conditions (centralized or peripheral) across increasing loads. Seventeen subjects (12 men and 5 women) randomly completed 2 series of CMJs with increasing loads separated by a 30-minute rest period between conditions. Subjects were loaded with either a weighted vest (centralized) or straight barbell (peripheral). A randomized, counterbalanced crossover design was used with incremental loads of 10, 20, 30, 40, and 50% of body mass added to the vest or barbell. Measures of peak force, acceleration, velocity, and power were calculated across each subphase of the CMJs. No significant differences were observed in kinetic or kinematic variables between loading conditions. Within each condition there were significant reductions (p < 0.05) in peak concentric velocity and acceleration, as well as significant increases (p < 0.05) in peak force when the external load increased. Furthermore, braking and propulsive phase duration significantly increased (p < 0.05) and jump height significantly decreased (p < 0.05) as the external load increased. Countermovement jump performance was similar in both central and peripheral loading, whereas increasing load significantly affected jump height, force, velocity, and acceleration variables irrespective of load position. The training stimulus from an external load placed centrally or peripherally is similar regardless of where it is positioned; however, from a practical perspective, a weighted vest may provide a more mobile and safer alternative than a barbell.
Multivariate analysis to determine secondary characters in selecting adaptive hybrid corn lines under drought stress

Fadhli N, Farid M, Rafiuddin, Efendi R, Azrai M, Anshori MF. 2020. Multivariate analysis to determine secondary characters in selecting adaptive hybrid corn lines under drought stress. Biodiversitas 21: 3617-3624. The development of adaptive hybrid corn varieties under drought stress needs an effective selection. Multivariate analysis has been reported can increase the effectiveness of selection in plants by attaching the secondary characters in the selection. Therefore, this concept also can be applied to develop adaptive corn varieties under drought stress. The objectives of this study are to determine the main secondary characters and select the best hybrid lines adaptive to drought stress. The experiment was arranged by a nested design, where replications nested under two environmental conditions, namely normal and drought stress. The main factor was genotypes consisted of 30 genotypes and was repeated three times. Moreover, the observations of this research consisted of 20 variables. The result of this research showed that the weight of harvested cob was an effective secondary character as a selection criterion along with productivity in selecting adaptive maize genotypes under drought stress. The number of green leaves was the character outside of the yield component could be as an alternative secondary character besides the weight of harvested cob. The selection results based on the weight of the harvested cob and productivity resulted in 12 hybrid corn lines considered adaptive to drought stress.
Treating Acute Myeloid Leukemia in Patients Presenting with COVID-19

Patients with hematological malignancies are at increased risk for severe COVID-19 with a high mortality rate. In AML, more and more patients are treated on an outpatient basis. This gives rise to two dilemmas in the face of COVID-19. The first one is whether to temporarily interrupt the oral antileukemia treatment and the second one is which patients should be intubated. Here, we describe our institutional approach and the underlying rationale in patients on lower intensity treatments for AML presenting with COVID-19
A Two-Stage Phase-Aware Approach for Monaural Multi-Talker Speech Separation

SUMMARY The simultaneous utterances impact the ability of both the hearing-impaired persons and automatic speech recognition systems. Recently, deep neural networks have dramatically improved the speech separation performance. However, most previous works only estimate the speech magnitude and use the mixture phase for speech reconstruction. The use of the mixture phase has become a critical limitation for separation performance. This study proposes a two-stage phase-aware approach for multi-talker speech separation, which integrally recovers the magnitude as well as the phase. For the phase recovery, Multiple Input Spectrogram In-version (MISI) algorithm is utilized due to its e ﬀ ectiveness and simplicity. The study implements the MISI algorithm based on the mask and gives that the ideal amplitude mask (IAM) is the optimal mask for the mask-based MISI phase recovery, which brings less phase distortion. To compensate for the error of phase recovery and minimize the signal distortion, an advanced mask is proposed for the magnitude estimation. The IAM and the proposed mask are estimated at di ﬀ erent stages to recover the phase and the magnitude, respectively. Two frameworks of neural network are evaluated for the magnitude estimation on the second stage, demonstrating the e ﬀ ectiveness and ﬂexibility of the proposed approach. The experimental results demonstrate that the proposed approach signiﬁcantly minimizes the distortions of the separated speech.
Sunflower pollen reduces a gut pathogen in worker and queen but not male bumble bees

1. Social insect castes and sexes differ in many ways, including morphology, behavior, and sometimes ploidy level. Recent studies have found that consuming sunflower pollen reduces the gut pathogen Crithidia bombi in workers of the common eastern bumble bee (Bombus impatiens). Here, this work is extended to the reproductive individuals that represent colony fitness – males and queens – to assess if the medicinal effects of sunflower pollen vary with bee caste and sex.
Pengaruh E-SPT, Sanksi, Sosialisasi, Pengetahuan Perpajakan, dan Moralitas pada Kepatuhan Wajib Pajak

Taxes are the largest source of state revenue in Indonesia. Compliance is an important factor in increasing tax revenue because tax compliance is the attitude of compliance, compliance, submission, and application of tax provisions. This research was conducted at KPP Pratama Tabanan using a sample of 390 non-employee taxpayers who were determined using the nonprobability sampling method with accidental sampling technique. The data analysis method used in this study is multiple linear regression analysis. The results found that, e-SPT, sanctions, socialization, tax knowledge, and morality had a positive effect on the tax compliance of non-employee individuals registered at the KPP Pratama Tabanan. Keywords: E-SPT; Sanctions; Socialization; Taxation Knowledge; Morality; Taxpayer Compliance.
Information-seeking behaviour of science and technology researchers in Nigeria: A survey of the Federal Institute of Industrial Research Oshodi

The science and technology sector plays an important role in the growth and diversification of the Nigerian economy. This article examines the information-seeking behaviour of science and technology researchers in Nigeria in order for the right approach to be taken with respect to information provision. A survey methodology was used for the study and 114 multidisciplinary science and technology researchers at the Federal Institute of Industrial Research Oshodi served as the respondents. The findings of the study revealed that science and technology researchers frequently sourced information from journals and knowledgeable persons; the Internet was the most frequent information source. The science and technology researchers used information for carrying out research and solving personal needs, among other things. The challenges identified in using information sources included outdated books and lack of adoption of electronic services. The study recommended that efforts should be directed at improving researchers’ access to information and the establishment of an institutional electronic database should be encouraged.
A proxy for privacy uncovering the surveillance ecology of mobile apps

The article develops a methodological and empirical approach for gauging the ways Big Data can be collected and distributed through mobile apps. This approach focuses on the infrastructural components that condition the disclosure of smartphone users’ data – namely the permissions that apps request and the third-party corporations they work with. We explore the surveillance ecology of mobile apps and thereby the privacy implications of everyday smartphone use through three analytical perspectives: The first focuses on the ‘appscapes’ of individual smartphone users and investigates the consequences of which and how many mobile apps users download on their phones; the second compares different types of apps in order to study the app ecology and the relationships between app and third-party service providers; and the third focuses on a particular app category and discusses the functional as well as the commercial incentives for permissions and third-party collaborations. Thereby, the article advances an interdisciplinary dialogue between critical data studies, political economy and app studies, and pushes an empirical and critical perspective on mobile communication, app ecologies and data economies.
Standards in education: reforms, stagnation and the need to rethink

ABSTRACT Countries around the world are striving to improve their educational systems with a view to improving their economy and society. In this global competition, national and international test results are of considerable interest. In this paper, we show that national testing in England and the USA have shown little or no improvement over the years. This finding is not isolated; it appears to be a global phenomenon. Data from large-scale international assessments such as PISA, TIMSS and PIRLS are remarkably stable over time. This paper reviews the trends from country-specific and international data and explores some of the reasons which have been offered for such stability. We argue that these explanations are insufficient and ways forward are discussed.
Postseismic Deformation Following the 2015 Mw7.8 Gorkha (Nepal) Earthquake: New GPS Data, Kinematic and Dynamic Models, and the Roles of Afterslip and Viscoelastic Relaxation

We report Global Positioning System (GPS) measurements of postseismic deformation following the 2015 Mw7.8 Gorkha (Nepal) earthquake, including previously unpublished data from 13 continuous GPS stations installed in southern Tibet shortly after the earthquake. We use variational Bayesian Independent Component Analysis (vbICA) to extract the signal of postseismic deformation from the GPS time series, revealing a broad displacement field extending >150 km northward from the rupture. Kinematic inversions and dynamic forward models show that these displacements could have been produced solely by afterslip on the Main Himalayan Thrust (MHT) but would require a broad distribution of afterslip extending similarly far north. This would require the constitutive parameter (a − b)σ to decrease northward on the MHT to ≤0.05 MPa (an extreme sensitivity of creep rate to stress change) and seems unlikely in light of the low interseismic coupling and high midcrustal temperatures beneath southern Tibet. We conclude that the northward reach of postseismic deformation more likely results from distributed viscoelastic relaxation, possibly in a midcrustal shear zone extending northward from the seismogenic MHT. Assuming a shear zone 5–20 km thick, we estimate an effective shear‐zone viscosity of ~3·1016–3·1017 Pa·s over the first 1.12 postseismic years. Near‐field deformation can be more plausibly explained by afterslip itself and implies (a − b)σ ~ 0.5–1 MPa, consistent with other afterslip studies. This near‐field afterslip by itself would have re‐increased the Coulomb stress by ≥0.05 MPa over >30% of the Gorkha rupture zone in the first postseismic year, and deformation further north would have compounded this reloading.
The Contribution of Forerunner to Storm Surges along the Vietnam Coast

Vietnam, located in the tropical region of the northwest Pacific Ocean, is frequently impacted by tropical storms. Occurrence of extreme water level events associated with tropical storms are often unpredicted and put coastal infrastructure and safety of coastal populations at risk. Hence, an improved understanding of the nature of storm surges and their components along the Vietnam coast is required. For example, a higher than expected extreme storm surge during Typhoon Kalmegi (2014) highlighted the lack of understanding on the characteristics of storm surges in Vietnam. Physical processes that influence the non-tidal water level associated with tropical storms can persist for up to 14 days, beginning 3–4 days prior to storm landfall and cease up to 10 days after the landfall of the typhoon. This includes the forerunner, ‘direct’ storm surge, and coastally trapped waves. This study used a continuous record of six sea level time series collected over a 5-year period (2013–2017) from along the Vietnam coast and Hong Kong to examine the contribution of the forerunner to non-tidal water level. The forerunner is defined as the gradual increase in mean water level, 2–3 days prior to typhoon landfall and generated by shore parallel winds and currents that result in a mean higher water level at the coast. Results indicated that a forerunner was generated by almost all typhoons, at least at one station, with a range between 20 and 50 cm. The forerunner contributed up to 50% of the water level change due to the storm. Combination of forerunner and onshore winds generated storm surges that were much higher (to 70 cm). It was also found that the characteristics of the typhoon (e.g., path, speed, severity and size) significantly influenced the generation of the forerunner. It is recommended that the forerunner that is not currently well defined in predictive models should be included in storm surge forecasts.
The effect of type of additive on rumen fermentation and digestion of grass silage in cattle

+ formic acid + acetic acid (LFA) and cellulase + glucose oxidase enzymes (E), The silages were fed at maintenance level to four dry cows, which had been equipped with a rumen cannula and a simple T-shaped duodenal cannula, in a digestibility experiment designed as a 4x4 latin square. The silages and a mixture of barley and oats (1:1) were given at a ratio of 70:30 on a dry matter basis. All the silages were well preserved, but fermentation in the silo was more restricted in silages ensiled with acid-based additives. The enzyme treatmentresulted in reduced levels of cell wall contents compared to the other silages. The apparent digestibilities oforganic matter (OM) and neutral detergent fibre with E silage were higher (P<0.05) than with the other silages. The microbial N flow at the duodenum was significantly higher (PcO.OOl) with the LFA diet compared to the other diets (NA 52; FA 53; LFA 66 and E 47 g N/d) and the efficiency of microbial protein synthesis tended to be lower with the E diet compared to the other diets (NA 31; FA 31; LFA 38 and E 20 g N/OM apparently digested in the rumen). The molar proportion of acetate in the rumen was significantly higher (PcO.OOl) and the proportion of propionate significantly lower (PcO.OOl) with acid silages than with E and NA silages. The proportion of butyrate was significantly higher with E silage compared to the others.
