Turbulent drag reduction over liquid-infused textured surfaces: effect of the interface dynamics

Direct numerical simulations of a turbulent channel with liquid infused surfaces made of longitudinal micro-ridges have been performed to study the effect of texture geometry and interface deformation. The flow conditions consider a viscosity ratio , several values of the micro-ridge pitch and two different Weber numbers, We = 0 and We = 50. The performance is analyzed in terms of drag reduction (DR) with respect to an equivalent smooth channel, and the results compared with those available for super-hydrophobic surfaces (SHS). It is found that, due to the relatively high viscosity of the liquid locked in the substrate, the drag reduction offered by LIS is substantially lower than the corresponding SHS. When reported in terms of the streamwise slip length normalized in wall units, the amount of DR obtained by LIS in the ideal case of flat interface collapses on the SHS data. The interface dynamics has a detrimental effect on the performance, that becomes particularly severe when the pitch increases. The degradation of DR is well parametrized by the log-law shift of the velocity profile, that is found to be proportional to the difference between the virtual origin of the mean flow and that experienced by the overlying turbulence.
Forensic Accounting Education in Bahrain: Academicians' Perceptions

The main purpose of this study is to report academicians' perceptions regarding the benefits, content, the mode of delivery, and the challenges facing forensic accounting education. Content analysis of course descriptions, interviews and questionnaire survey were used to collect the data. The results show that "promote responsible corporate governance" and "prepare students to engage in fraud examination" are the most important benefits of forensic accounting education. Twenty-six topics on forensic accounting were proposed to be integrated into the accounting curriculum. The respondents perceive all topics as important and the most important are: financial statements fraud, professional standards pertaining to forensic accounting, and legal elements of fraud. Lack of faculty interest was perceived as the main obstacle to providing proper forensic accounting education. Finally, there were no significant differences between respondents' characteristics (i.e., gender, educational qualifications and work experience) and their perceptions regarding the benefits and obstacles of forensic accounting. The study concludes that a model curriculum in accounting would be to include forensic accounting as a separate course in the accounting program and to be delivered at the undergraduate level jointly by both specialized academicians and practitioners.
Labor Market Nationalization Policies and Exporting Firm Outcomes: Evidence from Saudi Arabia

In the past decade, Gulf countries have imposed hiring quotas to promote native participation in the private sector and address unemployment. We explore how one such policy, Nitaqat in Saudi Arabia, affected exporting firms. We find that while the policy increased Saudi employment by these firms, it came at a cost. In the year following implementation, relative to firms above the quota, firms below were 1.5 percentage points more likely to exit the market and 7 percentage points less likely to export, and conditional on exporting, their exports fell by 10%–20%. These short-term effects persisted for at least 3 years.
Journey to the Self: In-Depth Case Studies of Trans Men’s Self-Construction through Body Work and Clothing

Abstract This research aims to explore transgender men’s embodied experiences of self-construction and discover the role of dress in their journey of outwardly becoming a man. In general, the stigma that sexual and gender minorities experience arises from the perception of appearance that has been institutionalized in a society within the binary gender system. Adopting Deleuzian theory, social comparison theory, and institutional theory as theoretical lenses, we conducted in-depth case studies of four trans males’ influencers’ narratives on YouTube and Instagram. Thematic analysis of the data revealed four themes: (1) Intention for self-documentation and public sharing of the journey of constructing identity, (2) self-consciousness of female body attributes and gender dysphoria as a result of social comparison, (3) reduced gender dysphoria through body modifications, and (4) consuming to conform: Adoption of gendered products for visual conformity and dilemma in fashion choices. Our findings demonstrated the role of dress (i.e. body modification, body supplements) in trans men’s self-construction as they attempt to create congruence between their internal sense of gender and their external presentation. The findings of this study provide theoretical disclosure of how Deleuzian theory and institutional theory are applied to a socially oppressed gender group.
Mitigation of drought stress on three summer crop species using the superabsorbent composite Gelatin-g-p(AA-co-AM)/RH

ABSTRACT A pot experiment was conducted to evaluate the capacity of superabsorbent composite (SAP) Gelatin-g-p(AA-co-AM)/RH to improve the performance of rice, maize, and peanut against terminal water stress. For each crop, pots (60 x 40 cm) were divided into two groups, the first comprised 12 SAP-free pots (control) and the second comprised 12 SAP-amended pots (0.5% w/w). After seed sowing, pots received four water regimes (100%, 75%, 50%, and 25% field capacity). Pots were watered according to the specified FC once a week along the growing season. Drought caused the significant reduction in growth and yield of tested crops; however, electrolytes leakage, malondialdehyde, free sugars, amino acids, proline, glycinebetaine, phenolics, and flavonoids contents were increased. SAP improved growth and yield by reducing drought deteriorations, compatible osmolytes, and antioxidant molecules. Meanwhile, SAP-induced accumulation of starch and soluble proteins, resulting in better survival, yield, and phytochemical attributes. Generally, SAP could enhance summer crops performance under water stress.

LEFT VENTRICULAR EJECTION FRACTION AFTER ACUTE MYOCARDIAL INFARCTION.

Objective: (1). To measure and compare Left Ventricular EjectionFraction (LVEF) after acute anterior wall and inferiorwall myocardial Infarction and correlate LVEF with clinical findingsin the patients. (2) To see prevalence of Left Ventricular Failure (LVF) after AMI. Design: Prospective observationalechocardiography based study.Setting: Sheikh Zayed Hospital Lahore. Period: From 2001 to 2002. A total of 60 (sixty)patients of (anterior or inferior) Acute Myocardial infarction (AMI) were included in the study. Patients were divided intwo groups on the basis of anterior myocardial wall MI (AWMI) or inferior myocardial wall MI (IWMI). Echocardiographywas done on all cases and ejection fraction was calculated by applying Simpson’s Rule and patients were examinedat the same time to see the presence of signs of left ventricular failure (LVF). (LVEF) was correlated with the findingsof LVF in these patients. Results: In patients with LVF mean ejection fraction (EF) was 37.13 with standard deviation(SD) of 8.4 %. In patients without failure the mean EF was 56.29% with SD of 3.75. In 30 patients of IWMI, mean EFwas 54.93% with SD of 6.86. In 30 patients of AWMI it was 46.07% with SD of 11.72. In all 60 patients minimum EFwas 30% and maximum was 60% with a mean of 50.50 with SD of 10.52. In AWMI, 53% patients had signs of leftventricular failure. In patients of IWMI, 13.3% had signs of LVF. Conclusions: AWMI causes more decrease in LVEF.LVF is more commonly associated with AWMI than IWMI. There is statistically significant difference in LVEF of patientswith and without LVF.
Recognition of Inter‐Cloud Versus Intra‐Cloud Controls on Droplet Dispersion With Applications to Microphysics Parameterization

Aerosols in the atmosphere can have a large impact on weather and climate. One of its lesser‐known impacts is the aerosol‐dispersion effect, which refers to the feedback between the aerosol (or cloud droplet) concentration and the relative dispersion of the droplet size distribution. This study attempts to reconcile the inconsistent sign of the correlation between aerosol number and droplet dispersion found in past studies by distinguishing local correlation from cloud‐mean correlation. We find that while the cloud‐mean correlation between aerosol concentration and droplet size relative dispersion is largely nonexistent, in‐cloud regions with high relative dispersion are typically associated with low local droplet concentration. Even stronger correlation is found with respect to the local activation fraction (the ratio of droplet concentration to total droplet and aerosol concentration). Based on this local correlation, we propose a new equation to diagnose the shape parameter in marine stratocumulus clouds for double moment bulk schemes in cloud‐resolving or large‐eddy simulations. This new equation is more physically realistic than many existing ones that are based on the weak cloud‐mean correlation.
Climatology of Tropical Cyclone Seed Frequency and Survival Rate in Tropical Cyclones

The relative contribution of tropical cyclone (TC) seed frequency and survival rate to TC frequency, together with factors affecting both, are investigated by focusing on monthly or interannual variations during boreal summers in 2000–2018. In this study, TC seeds are defined as weak lower‐tropospheric vortices. The results show that variation in TC frequency is controlled mainly by the survival rate interannually and horizontally. Survival rates vary with environmental fields, particularly those represented by a genesis potential index and thermodynamic variables at the initial stage of corresponding TC seeds, whereas the variation in TC seed frequency is correlated with monthly mean lower‐tropospheric relative vorticity and vertical velocity. These results suggest that large‐scale environmental fields affect TC frequency mainly through the survival rate, and low‐level vorticity and vertical motion are related to the TC seed frequency.
Healthy Habits and Emotional Balance in Women during the Postpartum Period: Differences between Term and Preterm Delivery

Breastfeeding could be considered as a vulnerable period, rising the risk to shift from optimism to pessimism. Preterm delivery is an event that increases postpartum maternal stress and depression, which can have a negative impact on breastfeeding and maternal–filial wellbeing. The adherence to healthy habits may have a positive influence on this vulnerable population. We aimed to analyze the impact of prematurity on maternal psychological aspects during postpartum and to study if adherence to the Healthy Food Pyramid influences psychological variables. Fifty-five breastfeeding women being attended in the Hospital Clínico San Carlos (Madrid, Spain) were recruited during the first day postpartum. The medical data were collected from the obstetrical records. The women answered an auto-administered questionnaire with several sections: sociodemographic characteristics, Perceived Stress Scale (PSS), and Life Orientation Test (LOT), at 14 days and 6 months postpartum, Adherence to the Healthy Food Pyramid Questionnaire (AP-Q) at 28 days postpartum and the Edinburgh Postpartum Depression Scale (EPDS) at 6 months postpartum. The PSS and LOT scores were not statistically different in mothers with preterm compared to term delivery either at 14 days or at 6 months postpartum. Longitudinally, the PSS did not show significant differences, but the LOT score was lower at 6 months compared to 14 days postpartum (p-Value = 0.046). A higher EPDS score was significantly found in mothers with preterm delivery (9.0 ± 4.7) than those with a term delivery (5.4 ± 4.2; p-value = 0.040). A significant and positive correlation was observed between the AP-Q score and LOT both at 14 days and 6 months postpartum. Conclusively, maternal optimism decreases during the postpartum period, women with preterm delivery being at risk of postpartum depression. Furthermore, there is a relationship between optimism and adherence to healthy habits. Healthcare professional counseling is essential during the entire breastfeeding period, particularly in vulnerable mothers with preterm delivery.
A GIS-Based Bivariate Logistic Regression Model for the Site-Suitability Analysis of Parcel-Pickup Lockers: A Case Study of Guangzhou, China

The site-suitability analysis (SSA) of parcel-pickup lockers (PPLs) is becoming a critical problem in last-mile logistics. Most studies have focused on the site-selection problem to identify the best site from given potential sites in specific areas, while few have solved the site-search problem to determine the boundary of the suitable area. A GIS-based bivariate logistic regression (LR) model using the supervised machine-learning (ML) algorithm was developed for suitability classification in this study. Eight crucial factors were selected from 27 candidate variables using stepwise methods with a training dataset in the best LR model. The variable of the proximity to residential buildings was more important than that to various commercial buildings, transport services, and roads. Among the four types of residential buildings, the most crucial factor was the proximity to residential quarters. A test dataset was employed for the validation process, showing that the best LR model had excellent performance. The results identified the suitable areas for PPLs, accounting for 8% of the total area of Guangzhou (GZ). A decision-maker can focus on these suitable areas as the site-selection ranges for PPLs, which significantly reduces the difficulty of analysis and time costs. This method can quickly decompose a large-scale area into several small-scale suitable areas, with relevance to the problem of selecting sites from various candidate sites.
‘A troublesome girl is pushed through’: Morality, biological determinism, resistance, resilience, and the Canadian child migration schemes, 1883–1939

This article critically analyses correspondence and decisions regarding children/young people who were included in the Canadian child migration schemes that ran between 1883 and 1939, and those who were deemed ‘undeserving’ and outside the scope of the schemes. Drawing on critical realist ontology, a metatheory that centralises the causal non-linear dynamics and generative mechanisms in the individual, the cultural sphere, and wider society, the research starts from the premise that the principle of ‘less or more eligibility’ lies at the heart of the British welfare system, both now and historically. Through analysing case files and correspondence relating to children sent to Canada via the Waifs and Strays Society and Fegan Homes, I shed light on the complex interplay between morality, biological determinism, resistance, and resilience in decisions around which children should be included or excluded. I argue that it was the complex interplay and nuance between the moral/immoral, desirable/undesirable, degenerate, and capable/incapable child that guided practice with vulnerable children in the late 1800s. In judgements around ‘deservedness’, related stigmas around poverty and ‘bad’ behaviour were rife. Within this, the child was punished for his/her ‘immoral tendencies’ and ‘inherited traits’, with little regard for the underlying reasons (e.g. abuse and neglect) for their (abnormal) behaviour and ‘mental deficiencies’.
Potential of hyperspectral imagery for nitrogen content retrieval in sugar beet leaves

Leaf nitrogen content (LNC) is one of the most important limiting key nutrients in sugar beet crops, so plant nitrogen status has to be carefully monitored throughout the plant life. In this study, close-range hyperspectral imaging was used to infer LNC from reflectance spectra in a non-destructive way and under in-field conditions. First, after acquisition, images were preprocessed in order to remove some sources of variability that were not correlated to LNC, such as specular reflection and spectral noise. For every hyperspectral image, the mean leaf spectrum was then evaluated and associated to the actual average LNC value measured on the same plants. Partial Least Square regression was used to calibrate a regression model. With six latent variables, LNC was accurately predicted with a low error and a high coefficient of determination (RMSECV = 1.72 g/kg; R2 = 0.86). When applied to individual spectra of hyperspectral images, this model led to a consistent LNC map of sugar beet leaves, i.e., LNC was low in old nitrogen-deficient leaves and it was high in young wide leaves. Such a mapping is therefore a valuable non-destructive evaluation tool to better understand how LNC is distributed within plants and to identify LNC-deficient zones.
WATER RELATIONS AND YIELD OF SESAME IN RELATION TO RIDGE WIDTH AND IRRIGATION REGIME

The present investigation was conducted at Tameia agriculture research station Fayoum governorate, Egypt, during 2010 and 2011 seasons to study the combined effect of ridge width treatments i.e. R 1 : ridges of 60 cm, R 2 : ridges of 80 cm and R 3 : ridges of 100 cm(beds planted from both sides) and irrigation regime treatments i.e. I 1 : irrigation at 40% Available Soil Moisture Depletion(ASMD), I 2 : irrigation at 60% (ASMD) and I 3 : irrigation at 80% (ASMD) on yield components, yield and some -3 cv. ). The split-plot design in randomized complatc block, with four replications was applied, where ridge width treatments were allocated to the main plots and the split ones were occupied with irrigation regime treatments. The main obtained results were as follows:-Plant height, -1 , seed , 1000-seed weight, seed yield (t ha -1 ) and seed oil content (%) were significantly affected by ridge width treatments and irrigation regime in both seasons. and seasonal ET C values, i.e. 132.57 and 129.30 cm ha -1 in 2010 and 2011 seasons, respectively. However, the lowest ET C values, i.e. 110.22 and 107.48 cm ha -1 were detected from planting on ridges of 100 cm width (beds) and irrigation at 80% ASMD in the two successive seasons. The crop coefficient (K C ) values for the treatments which gave the highest seed yield and ET C values (R 1 I 1 ) were 0.42, 0.62, 0.80 and 0.57 for May, June, July and August months, respectively, (average of the two seasons). The highest water use efficiency values, i.e. 0.261 and 0.253 kg seeds m- 3 water consumed were resulted from planting on ridges of 60 cm width and irrigation at 40% ASMD, in 2010 and 2011 seasons, respectively. It could be concluded that planting sesame on wide ridges of 100 cm (beds) saved about 7.7% (423 m 3 ha -1 ) in water evapotranspiration and gave acceptable yield.
Using Multivariate Regression and ANN Models to Predict Properties of Concrete Cured under Hot Weather

Concrete is an important construction material. Its characteristics depend on the environmental conditions, construction methods, and mix factors. Working with concrete is particularly tricky in a hot climate. This study predicts the properties of concrete in hot conditions using the case study of Rawalpindi, Pakistan. In this research, variable casting temperatures, design factors, and curing conditions are investigated for their effects on concrete characteristics. For this purpose, water–cement ratio (w/c), in-situ concrete temperature (T), and curing methods of the concrete are varied, and their effects on pulse velocity (PV), compressive strength (fc), depth of water penetration (WP), and split tensile strength (ft) were studied for up to 180 days. Quadratic regression and artificial neural network (ANN) models have been formulated to forecast the properties of concrete in the current study. The results show that T, curing period, and moist curing strongly influence fc, ft, and PV, while WP is adversely affected by T and moist curing. The ANN model shows better results compared to the quadratic regression model. Furthermore, a combined ANN model of fc, ft, and PV was also developed that displayed higher accuracy than the individual ANN models. These models can help construction site engineers select the appropriate concrete parameters when concreting under hot climates to produce durable and long-lasting concrete.
A Meta-Analysis on the Longitudinal, Age-Dependent Effects of Violent Video Games on Aggression

ABSTRACT A large body of research exists on the causal relationship between violent video game (VVG) consumption and aggression. However, no meta-analytic studies to date have specifically examined the influence of age on these effects. We investigated the age-dependent relationship between VVG consumption and subsequent physically aggressive behavior in a meta-analytic procedure based on longitudinal studies. Further exploratory analyses addressed the moderating effect of the year of data collection. A random-effects meta-analysis with 30 effect sizes from 21 studies (N = 15,836) yielded a significant and relevant positive effect of VVG on subsequent physically aggressive behavior (r = .21). The effect was reduced but maintained at r = . 11 when controlling for aggression at T1. Polynomial regression showed a significant U-shaped age trajectory with a peak in early adolescence at the age of 14. Year of data collection did not correlate with the effect size. Consequently, we confirm the results of other meta-analyses, with the added finding of a peak of effect sizes in early adolescence. The empirical finding provide support for basing age ratings for game publication on potential adverse behavioral effects.
Rotating thermal convection: surface turbulence observed with altimetry and thermal radiometry

The surface dynamics of the rotating thermal convection are examined in finely resolved laboratory flows. Deep rotating convection creates geostrophic turbulent flow at the surface, the regime of convection relevant to flows observed in deep convection sites in the ocean or in the atmospheres of the gas giants Jupiter and Saturn. Spectral analyses reveal a dual energy cascade of the surface kinetic energy and a downscale cascade of surface buoyancy. The spectral slopes of these quantities are found to be very similar to each other. This property is further confirmed theoretically; it was showed in particular that buoyancy is proportional to velocity in the subsurface thermal boundary layer.
