Unified equations to predict residual flexural tensile strength of lightweight steel fiber‐reinforced concrete
Authors: Gondokusumo Gilbert Sebastiano , Venkateshwaran Akshay , Tan Kiang Hwee , Liew J. Y. Richard 
Published: June 2021

AbstractIn this paper, novel unified equations for predicting the residual flexural tensile strength of normal‐weight, lightweight, and ultra‐lightweight steel fiber‐reinforced concrete (SFRC) are proposed. The unified equations were obtained by conducting multiple nonlinear regression analysis on the test results from 60 notched prism tests conducted according to EN 14651. The proposed unified equations account for fiber geometry, fiber content, concrete compressive strength, and concrete density. Unlike existing prediction equations, which can only predict the flexural tensile strength of normal‐weight SFRC, the proposed equations are applicable for SFRC with varying densities. Test results from the literature verified the accuracy of the proposed equations to within 10% of observed values, on average. Compared to the existing equations, the proposed unified equations were better at predicting residual flexural tensile strength of both normal‐weight and lightweight steel fiber reinforced concrete.

Published: June 2021

AbstractThe muzzle region of dogs contains various composite tissues, which are challenging to recreate during reconstruction. Small or moderate facial/nasal defects can be closed primarily or left for second‐intention healing. However, larger defects require the application of composite tissue or labial advancement flaps. Axial pattern flaps based on the caudal auricular artery, superficial temporal artery (STA), angularis oris artery, and other cutaneous arteries have been reported. In our case, we aim to report the reconstruction of a large composite defect of the rostral and dorsal nasal regions in a dog using an augmented, axial myocutaneous flap based on bilateral STAs. This is a clinical report on a spayed female mixed‐breed dog (age, 7 years; weight, 15 kg), in which a large‐scale nasal–facial composite tissue defect was surgically reconstructed using an axial myocutaneous flap based on bilateral STA branches. A delay technique was applied to prefabricate the flap to enrich the blood supply. New nostrils were created on a folded, rostral hard palate. As a result, the axial tube rotational flap was successfully transferred. The use of delay technique for prefabricating the tube flap optimized its size and survival. In addition to the folded rostral hard palate, the flap fully closed the defects on the face and nose. Functional and cosmetic outcomes were satisfactory, with minimal donor‐site morbidity. In, conclusion, a large‐scale nasal–facial defect in a dog was successfully reconstructed using an augmented tube pedicle flap based on the bilateral STAs, which may, thus, be used to repair very large facial‐nasal defects in dogs.

AbstractThe aim of this study was to evaluate antioxidant, antihyperlipidemic and hypotensive properties of pomegranate peel (PP) on antioxidant status, fat deposition, lipid peroxidation and pulmonary hypertensive response in broiler chickens. A total of 375 one‐day‐old male broilers (Cobb 500) were randomly assigned to five treatments included dietary PP levels of 0, 2.5, 5.0, 7.5 and 10 g/kg. Supplementation of PP at 7.5 and 10 g/kg resulted in significant upregulation of hepatic catalase (p < 0.004) and superoxide dismutase1 (SOD1; p < 0.05), which reflected in decreased concentration of circulatory malondialdehyde (MDA). Dietary inclusion of PP at 7.5 and 1.0 g/kg significantly decreased serum concentrations of triglycerides (p < 0.004) and cholesterol (p < 0.006) with concomitant decrease in abdominal fat deposition (p < 0.05). The antihyperlipidemic effect of PP was mediated through down‐regulation of peroxisome proliferator activated receptor alpha (PPARα). Hypotensive effect of PP was also observed at 7.5 and 10 g/kg as reduced heart weight and the right‐to‐total ventricular weight ratio (RV/TV) and decreased mortality from pulmonary hypertension. The hypotensive property of PP was associated with increased concentration of serum nitric oxide. In conclusion, this study revealed antioxidative, antihyperlipidemic and hypotensive effects of PP at 7.5 and 10 g/kg in broiler chickens exposed to hypobaric hypoxia. Health‐beneficial effects of PP suggest this product as a promising multi‐functional phytogenic feed additive for broiler chickens.
Dual subtractions

Published: June 2021

Abstract
We propose a novel local subtraction scheme for the computation of Next-to-Leading Order contributions to theoretical predictions for scattering processes in perturbative Quantum Field Theory. With respect to well known schemes proposed since many years that build upon the analysis of the real radiation matrix elements, our construction starts from the loop diagrams and exploits their dual representation. Our scheme implements exact phase space factorization, handles final state as well as initial state singularities and is suitable for both massless and massive particles.
Dimension spectrum of infinite self-affine iterated function systems

AbstractGiven an infinite iterated function system (IFS) $${\mathcal {F}}$$

Published: June 2021

AbstractRheumatoid arthritis (RA), a long-term auto-immune condition is a challenging condition for patients to manage. Goals of treatment include reducing pain, decreasing inflammation, and improving an individual’s overall function. Increasingly technology is being utilised to support patients to self-manage their condition. The aim of this systematic narrative review was to synthesise and critically appraise published evidence concerning the effectiveness of tele-health interventions to support self-management in RA. Bibliographic databases searched from 2014 to March 2020 included MedLINE, Embase, Cochrane Library. Search strategy combined the following concepts: (1) rheumatoid arthritis, (2) tele-health interventions, and (3) self-management. Only randomised controlled trials (RCTs) involving adults with RA were included. Titles, abstracts, full-text articles were screened, any discrepancies were checked by a second reviewer. Risk of bias was assessed using Cochrane risk of bias tool and data were extracted utilising the Cochrane data collection form for RCT interventions along with the TiDier checklist. Due to high heterogeneity, results were not meta-analysed and instead data were synthesised narratively. The search identified 98 articles, seven were included. The completed RCTs varied in the nature of the interventions, duration/severity of RA, outcomes measured and effectiveness of the interventions. The completed RCTs included a total of 791 participants Disease duration was largely between 4 and 10 years and disease severity on average was moderate. There was extensive variation in intervention components, theories underpinning theories and outcomes measured. Five RCTs reported a positive effect on factors such as disease activity, medication adherence, physical activity and self-efficacy levels. This study suggests that tele-health interventions that are well-designed, tailored and multi-faceted can help to achieve positive self-management outcomes in RA. None of the studies showed evidence of harm.

Abstract
Purpose
This study evaluates the performance of a mobile and compact hybrid C-arm scanner (referred to as IXSI) that is capable of simultaneous acquisition of 2D fluoroscopic and nuclear projections and 3D image reconstruction in the intervention room.

Results
The impact of slightly misaligning the IXSI modalities (in an off-focus geometry) was investigated for the reduction of the fluoroscopic and nuclear interference. The 2D and 3D nuclear image quality of IXSI was compared with a clinical SPECT/CT scanner by determining the spatial resolution and sensitivity of point sources and by performing a quantitative analysis of the reconstructed NEMA image quality phantom. The 2D and 3D fluoroscopic image of IXSI was compared with a clinical CBCT scanner by visualizing the Fluorad A+D image quality phantom and by visualizing a reconstructed liver nodule phantom. Finally, the feasibility of dynamic simultaneous nuclear and fluoroscopic imaging was demonstrated by injecting an anthropomorphic phantom with a mixture of iodinated contrast and 99mTc.

Conclusion
Due to the divergent innovative hybrid design of IXSI, concessions were made to the nuclear and fluoroscopic image qualities. Nevertheless, IXSI realizes unique image guidance that may be beneficial for several types of procedures.

Key Points
• IXSI can perform time-resolved planar (2D) simultaneous fluoroscopic and nuclear imaging.
• IXSI can perform SPECT/CBCT imaging (3D) inside the intervention room.
Measuring Gender Role Conflict, Internalized Stigma, and Racial and Sexual Identity in Behaviorally Bisexual Black Men

Published: June 2021

AbstractBlack men who have sex with men and women (BMSMW) experience pressure to fill hypermasculine ideals and may not identify with “gay” cultural norms. Existing measures of gender role expectations and internalized homophobia are not culturally appropriate for BMSMW. Researchers generally measure categorical identification with race, gender, and sexual orientation groups separately, whereas BMSMW may identify with multiple categories. We modified the Gender Role Conflict Scale to create the M-GRCS and the Internalized Homophobia Scale to include biphobia (Internalized Bi/Homophobia Scale, IBHS). To examine identification at the intersection of race, gender, and sexual orientation, we created 11 Integrated Race and Sexuality Scale (IRSS) items. With data from 429 BMSMW, we conducted exploratory factor analysis of the 59 items using categorical principal axis factoring with unweighted least squares extraction and Promax factor rotation. We created simple-summated multi-item scales and evaluated their construct validity. The rotated solution yielded four factors with 47 items and a simple factor structure: M-GRCS defined two factors (α = .93 for restricted emotionality/affection; .87 for success/power/competition); the IBHS (α = .89) and IRSS (α = .74) each defined a single factor. The IRSS factor was positively correlated with the Lukwago Racial Pride Scale, r(417) = .40. The IBHS factor was negatively correlated with the IRSS factor, r(414) = − .22. The two M-GRCS factors suggest that the construct of hypermasculinity impacts BMSMW. The high IBHS reliability indicates that homophobia and biphobia were positively correlated in this sample. These three scales have potential for future studies with BMSMW.
Sensitivity of the Second Order Homogenized Elasticity Tensor to Topological Microstructural Changes

Published: June 2021

AbstractThe multiscale elasticity model of solids with singular geometrical perturbations of microstructure is considered for the purposes, e.g., of optimum design. The homogenized linear elasticity tensors of first and second orders are considered in the framework of periodic Sobolev spaces. In particular, the sensitivity analysis of second order homogenized elasticity tensor to topological microstructural changes is performed. The derivation of the proposed sensitivities relies on the concept of topological derivative applied within a multiscale constitutive model. The microstructure is topologically perturbed by the nucleation of a small circular inclusion that allows for deriving the sensitivity in its closed form with the help of appropriate adjoint states. The resulting topological derivative is given by a sixth order tensor field over the microstructural domain, which measures how the second order homogenized elasticity tensor changes when a small circular inclusion is introduced at the microscopic level. As a result, the topological derivatives of functionals for multiscale models can be obtained and used in numerical methods of shape and topology optimization of microstructures, including synthesis and optimal design of metamaterials by taking into account the second order mechanical effects. The analysis is performed in two spatial dimensions however the results are valid in three spatial dimensions as well.
The Precarious Space for Mourning: Sick Leave as an Ambiguous Topic in Bereaved Parents’ Accounts of the Return to Everyday Life After Reproductive Loss
Authors: Kristvik Ellen 
Published: June 2021

AbstractThis article addresses conflicting concerns related to space for mourning in Norway. It draws on material from qualitative interviews with bereaved parents who have lost a child in stillbirth. Space for mourning, and the need for sick leave, arose as a crucial concern and complex issue in these interviews. Although initiatives have been developed to introduce grief as a valid category in diagnostic repertoires, it is not a legitimate basis for sick leave in the acute phase. Common alternatives have been referrals to psychic instability or depression. Both variations represent a medicalization of the normal with implications that need to be addressed, and which this article discusses from the bereaved parents’ point of view. Extended parental leave, and the introduction of grief allowance, are possible alternatives for the provision of space in normal but demanding times of grief. Despite not yet part of the repertoire for gatekeepers in the Norwegian welfare state, they are part of the public discourse. Besides a crucial acknowledgment of the grief of the parents, these options also represent possibilities for preventing a pathologization of what is a normal rite of passage.
The importance of policy design fit for effectiveness: a qualitative comparative analysis of policy integration in regional transport planning

Published: June 2021

AbstractPolicy design has returned as a central topic in public policy research. An important area of policy design study deals with effectively attaining desired policy outcomes by aligning goals and means to achieve policy design fit. So far, only a few empirical studies have explored the relationship between policy design fit and effectiveness. In this paper, we adopt the multilevel framework for policy design to determine which conditions of policy design fit—i.e., goal coherence, means consistency, and congruence of goals and means across policy levels—are necessary and/or sufficient for policy design effectiveness in the context of policy integration. To this end, we performed a qualitative comparative analysis of Dutch regional transport planning including all twelve provinces. Outcomes show no condition is necessary and two combinations of conditions are sufficient for effectiveness. The first sufficient combination confirms what the literature suggests, namely that policy design fit results in policy design effectiveness. The second indicates that the combination goal incoherence and incongruence of goals and means is sufficient for policy design effectiveness. An in-depth interpretation of this counterintuitive result leads to the conclusion that for achieving policy integration the supportive relationship between policy design fit and policy design effectiveness is less straightforward as theory suggests. Instead, results indicate there are varying degrees of coherence, consistency, and congruence that affect effectiveness in different ways. Furthermore, outcomes reveal that under specific circumstances a policy design may be effective in promoting desired policy integration even if it is incoherent, inconsistent, and/or incongruent.
The Different Faces of Social Tolerance: Conceptualizing and Measuring Respect and Coexistence Tolerance
Authors: Velthuis Evi , Verkuyten Maykel , Smeekes Anouk 
Published: June 2021

AbstractIn the theoretical literature on tolerance a distinction is proposed between coexistence and respect tolerance. In three studies with four national samples of Dutch majority members, we demonstrate that these two forms of tolerance can be distinguished empirically in relation to different immigrant target groups. The findings of all studies further show that the more principled respect tolerance was negatively associated with prejudice towards immigrants, and positively associated with the acceptance of concrete minority practices, above and beyond prejudice. However, the positive association between respect tolerance and acceptance of practices was weaker for people who were more strongly concerned about the continuity of their national cultural identity. Overall, the more pragmatic coexistence tolerance was found to have no independent association with prejudicial feelings and with the acceptance of minority practices. The findings indicate that stimulating respect tolerance might be particularly helpful for improving intergroup relations in culturally diverse societies.

AbstractThe impact of gold mining activities on the Lom River in Wakaso (Adamawa Cameroon) and the potential of Moringa Oleifera seeds for the removal of pollutants from wastewater is evaluated on this paper. Water samples were collected for physicochemical (hydrogen potential, electrical conductivity, turbidity and suspended solids) and chemical (major ions and heavy metals) analyses. To evaluate the effect of mining activities on waters and sediments, a combination of multivariate statistical analysis (MSA) and methods to assess the sediment quality was used. The restorative effect of Moringa oleifera seeds was studied with the determination of the maximum removal efficiencies and the maximum adsorption capacities. The results of the physicochemical characterization of waters showed that these waters were slightly acidic to slightly basic (6.12–8.12), weakly conductive (185.8–584.1 μS cm−1), turbid (345–801NTU) and had high content of suspended solids (167–700 mg L−1). The average concentrations of studied heavy metals (Ni, Cd, Fe, Mn, As and Hg) in waters exceeded the limits recommended by the World Health Organization (WHO) standards. Physicochemical characterization of sediments revealed that they were acidic to neutral (5.95–6.80) and organic matter (OM) content ranged from 11.11 to 15.78%. The concentrations of studied trace metals (Ni, Cd, Fe, Hg, Mn and As) in sediments were below the limits recommended by the WHO except for Cd and Hg. The study of the capacity of Moringa oleifera seeds to remove pollutants in waters showed that 54% of the electrical conductivity, 80% of turbidity and 94% of suspended solids were reduced. The maximum removal efficiency of 91.66, 92.30 and 24.48 and the maximum adsorption capacity of 2.4, 2.6 and 16.6 mg g−1were observed for Cd (II), Hg (II) and Fe (II), respectively. Thus, the Moringa oleifera seeds which are locally available natural bio-adsorbent exhibit attractive property to treat wastewater.

Published: June 2021

AbstractHigh-quality, ultra-precise processing of surfaces is of high importance for high-tech industry and requires a good depth control of processing, a low roughness of the machined surface and as little as possible surface and subsurface damage but cannot be realized by laser ablation processes. Contrary, electron/ion beam, plasma processes and dry etching are utilized in microelectronics, optics and photonics. Here, we have demonstrated a laser-induced plasma (LIP) etching of single crystalline germanium by an optically pumped reactive plasma, resulting in high quality etching. A Ti:Sapphire laser (λ = 775 nm, EPulse/max. = 1 mJ, t = 150 fs, frep. = 1 kHz) has been used, after focusing with a 60 mm lens, for igniting a temporary plasma in a CF4/O2 gas at near atmospheric pressure. Typical etching rate of approximately ~ 100 nm / min and a surface roughness of less than 11 nm rms were found. The etching results were studied in dependence on laser pulse energy, etching time, and plasma – surface distance. The mechanism of the etching process is expected to be of chemical nature by the formation of volatile products from the chemical reaction of laser plasma activated species with the germanium surface. This proposed laser etching process can provide new processing capabilities of materials for ultra—high precision laser machining of semiconducting materials as can applied for infrared optics machining.

Published: June 2021

AbstractThe traveling salesman problem (TSP) is one of the best-known combinatorial optimization problems. Many methods derived from TSP have been applied to study autonomous vehicle route planning with fuel constraints. Nevertheless, less attention has been paid to reinforcement learning (RL) as a potential method to solve refueling problems. This paper employs RL to solve the traveling salesman problem With refueling (TSPWR). The technique proposes a model (actions, states, reinforcements) and RL-TSPWR algorithm. Focus is given on the analysis of RL parameters and on the refueling influence in route learning optimization of fuel cost. Two RL algorithms: Q-learning and SARSA are compared. In addition, RL parameter estimation is performed by Response Surface Methodology, Analysis of Variance and Tukey Test. The proposed method achieves the best solution in 15 out of 16 case studies.
