Nonsimilar solution of a boundary layer flow of a Reiner–Philippoff fluid with nonlinear thermal convection

The thermodynamics modeling of a Reiner–Philippoff‐type fluid is essential because it is a complex fluid with three distinct probable modifications. This fluid model can be modified to describe a shear‐thinning, Newtonian, or shear‐thickening fluid under varied viscoelastic conditions. This study constructs a mathematical model that describes a boundary layer flow of a Reiner–Philippoff fluid with nonlinear radiative heat flux and temperature‐ and concentration‐induced buoyancy force. The dynamical model follows the usual conservation laws and is reduced through a nonsimilar group of transformations. The resulting equations are solved using a spectral‐based local linearization method, and the accuracy of the numerical results is validated through the grid dependence and convergence tests. Detailed analyses of the effects of specific thermophysical parameters are presented through tables and graphs. The study reveals, among other results, that the buoyancy force, solute and thermal expansion coefficients, and thermal radiation increase the overall wall drag, heat, and mass fluxes. Furthermore, the study shows that amplifying the space and temperature‐dependent heat source parameters allows fluid particles to lose their cohesive force and, consequently, maximize flow and heat transfer.
Study on the Shear Failure of Reinforced Concrete Beams Using Extended Finite Element Method (XFEM)

This research concerns with the fracture behavior of reinforced concrete beams without shear reinforcement numerically. The software ABAQUS is adapted to simulate the crack propagation using the eXtended Finite Element Method (XFEM), taking into account materials nonlinearities using concrete damage plasticity CDP criteria. XFEM is used to solve the discontinuity problems in the simulation. The maximum principal stress failure criterion is selected for damage initiation, and an energy-based damage evolution law based on a model-independent fracture criterion is selected for damage propagation. The traditional nonlinear finite element analysis is used to specify the crack initiation position, which is required to specify the crack location in the analysis of beams using XFEM. Three-dimensional reinforced concrete beam models are investigated subjected to three and four-point loading tests. Simply supported beams under the effect of applied static load are investigated. An elastic perfectly plastic model is used for modeling the longitudinal steel bars. The main variables considered in the study are beam depth and the shear span with beam length. The numerical results are compared with the available experimental results to demonstrate the applicability of the model. The XFEM provides the capability to predict the concrete member fracture behavior.
Is Cell Sharing Associated with Wellbeing, Misconduct and Prison Climate? Evidence from a Dutch Study

Despite international guidelines, it is common practice in many European countries for prisoners to share a cell. In many cases this may be a measure to cope with overcrowding, but in the Netherlands it is a policy measure to reduce costs and flexibly adjust capacity. While the harms of overcrowding are widely recognised, less is known about the effects of cell sharing in non-overcrowded conditions. This study considers the association between cell sharing, wellbeing, misconduct, and prison climate, using data from a national survey study among Dutch prisoners (N = 3408). Findings show that cell sharing is associated with poorer ratings of wellbeing and prison climate, especially for people who prefer a single cell. Prisoners in double cells who do not get along with their cellmate report more misconduct. These findings reinforce recommendations to house people in single cells, unless they prefer otherwise.
Nutrition knowledge and practice of dietary diversity among people living with HIV in a resource-limited setting: a multi-center study

Introduction: Adequate nutrition plays a major role in delaying disease progression and improving quality of life of people living with human immunodeficiency virus (PLHIV). Therefore, it is important to assess their nutrition knowledge and practice of dietary diversity, especially in resource-limited settings, where most HIV infections occur. Aim of the study was to assess the nutrition knowledge and dietary diversity practice of PLHIV in a resource-limited setting. Material and methods: This was a health facility-based cross-sectional analytical study conducted at two tertiary HIV clinics in Enugu, Nigeria. Using a systematic random sampling technique, 370 adult HIV patients were recruited. Bivariate and multivariate logistic regression analyses were per-formed to identify factors associated with good nutrition knowledge and high dietary diversity among respondents. P -value < 0.05 was considered statistically significant. Results: Good nutrition knowledge was observed in 69.7% of the respondents, while 60.0% had high dietary diversity. In multivariate analysis, secondary educational level (AOR: 0.54; 95% CI: 0.29-0.97; p = 0.040) and earning a family monthly income of 31,000-60,000 (AOR: 2.12; 95% CI: 1.11-4.06; p = 0.024) were predictors of good nutrition knowledge. Number of children in a household (AOR: 2.09; 95% CI: 1.19-3.67) was predictive of high dietary diversity. Conclusions: Educational level and family monthly income are predictors of nutrition knowledge, while number of children in a household is a predictor of dietary diversity. Nutrition education should be incorporated into HIV care program targeting those with low educational levels and low family monthly incomes for improvement of their nutrition knowledge.
Correlation between RASSF1A Methylation in Cell-Free DNA and the Prognosis of Cancer Patients: A Systematic Review and Meta-Analysis

Background Although the effects of methylation of the Ras association domain-containing protein 1 isoform A (RASSF1A) gene in cell-free DNA on the outcomes of patients with different types of cancer have been reported, the results are inconsistent. Objective : To explore the relationships between RASSF1A methylation in cell-free DNA and the outcomes of cancer patients. Methods The PubMed, Embase, and Web of Science databases were searched for papers related to this topic on December 8, 2021. The retrieved articles were screened by two independent researchers, following which the methodological quality of the selected studies was evaluated using the Newcastle-Ottawa Scale. Additionally, hazard ratios were calculated, and publication bias of the studies was determined using Egger's test. Results Nine relevant publications involving a combined total of 1254 patients with different types of cancer were included in this study. The combined results of the random effects models yielded a hazard ratio of 1.73 (95% confidence interval: 1.31, 2.29; P < 0.001), which suggested there was a significant association between RASSF1A methylation and overall survival, and patients with an RASSF1A methylation status had a significantly increased risk of total death. Moreover, the Egger test result suggested there was no significant publication bias among the included studies. Conclusions The methylation of RASSF1A in cell-free DNA in cancer patients was observably associated with an increased risk of poor overall survival.
Effect of bioceramic root canal sealers on the bond strength of fiber posts cemented with resin cements

Abstract This study aimed to evaluate the influence of calcium silicate-based sealers on the bond strength of fiber posts using conventional and self-adhesive resin cement. Sixty single-rooted teeth were selected. The canals were prepared with a reciprocating instrument 40.06. The roots were randomly distributed in six groups (n = 10) according to the strategies for root canal filling and fiber posts cementation: AH Plus/RelyX ARC; AH Plus/RelyX U200; Bio C Sealer/RelyX ARC; Bio C Sealer/RealyX U200; Sealer Plus BC/RelyX ARC; and Sealer Plus BC/RelyX U200. The roots were transversally sectioned, and one slice per post-third was obtained. The push-out test was performed at a crosshead speed of 1mm/min. The failure patterns were described after assessment with a stereomicroscope with a 10× magnification. Bond strength was calculated and analyzed using the ANOVA and Tukey test. AH Plus did not influence the bond strength of fiber posts cemented with conventional (RelyX ARC) or with self-adhesive resin cement (RelyX U200). The lowest bond strength values were obtained when calcium silicate-based sealers were associated with conventional resin cement (Bio C Sealer/RelyX ARC and Sealer Plus BC/RelyX ARC). Except for Sealer Plus BC/RelyX ARC, all groups presented lower bond strength at the apical portion compared to the cervical portion of the post. Adhesive failures between cement and post and cement and dentin were predominant (55.3%). Calcium silicate-based sealers decreased the bond strength of fiber posts cemented with conventional resin cement.
A Single-Cell Raman Spectroscopy Analysis of Bone Marrow Mesenchymal Stem/Stromal Cells to Identify Inter-Individual Diversity

The heterogeneity of stem cells represents the main challenge in regenerative medicine development. This issue is particularly pronounced when it comes to the use of primary mesenchymal stem/stromal cells (MSCs) due to a lack of identification markers. Considering the need for additional approaches in MSCs characterization, we applied Raman spectroscopy to investigate inter-individual differences between bone marrow MSCs (BM-MSCs). Based on standard biological tests, BM-MSCs of analyzed donors fulfill all conditions for their characterization, while no donor-related specifics were observed in terms of BM-MSCs morphology, phenotype, multilineage differentiation potential, colony-forming capacity, expression of pluripotency-associated markers or proliferative capacity. However, examination of BM-MSCs at a single-cell level by Raman spectroscopy revealed that despite similar biochemical background, fine differences in the Raman spectra of BM-MSCs of each donor can be detected. After extensive principal component analysis (PCA) of Raman spectra, our study revealed the possibility of this method to diversify BM-MSCs populations, whereby the grouping of cell populations was most prominent when cell populations were analyzed in pairs. These results indicate that Raman spectroscopy, as a label-free assay, could have a huge potential in understanding stem cell heterogeneity and sorting cell populations with a similar biochemical background that can be significant for the development of personalized therapy approaches.
Understanding Teamwork Behaviors in the Use of New Ways of Working

New Ways of Working practices like activity-based working and home-based work lead to different behaviors of employees. Due to these NWW practices, employees choose their own preferred times and places to work – albeit to a certain extent and within certain boundaries. This might have an impact on the possibilities for teamwork. Therefore, we suppose that teamwork and teamwork behaviors might moderate the relationship between NWW and outcomes. Does teamwork behavior have an influence on the relation of NWW and productivity or organizational commitment? And how, is it a positive or a negative influence on these relations? This chapter reports the results of an explorative study on the relationship between NWW practices, teamwork behavior, productivity, and organizational commitment. Quantitative data from the questionnaire will illustrate the main issues: the complex linkages between the four components of NWW, the outcome variables, and the effect of different components of teamwork behavior. This chapter describes the issue of teamwork and provides new data on the actual use and effectiveness of the different components of teamwork behaviors.
Gastrointestinal Dysfunction Impact on Life Quality in a Cohort of Russian Patients with Parkinson's Disease I-III H&Y Stage

Background There are still no clearly proven methods to slow down or stop the progression of Parkinson's disease (PD). Thus, improving the quality of life (QoL) of patients with PD becomes of primary importance. Autonomic dysfunction and its symptoms are known to worsen the quality of life in PD, but the degree of this influence is underinvestigated. Particularly, impacts of the separate significant gastrointestinal symptoms, such as dyspepsia, constipation, and abdominal pain, in PD should be more precisely evaluated with the help of specific scales. Objective To assess the impacts of gastrointestinal dysfunction and its symptoms on PD patient's QoL using PDQ-39. Methods 111 PD patients in the I-III Hoehn and Yahr (H&Y) stage were enrolled in the study. The following scales were applied: UPDRS III, PDQ-39, GSRS, GDSS, MMSE, BDI, STAI-S, and STAI-T. Results The linear regression model showed that the PDQ-39 SI depended on summary assessments GSRS-SI (β = 0.333, p < 0.001), BDI (β = 0.463, p < 0.001), and UPDRS III (β = 0.163, p < 0.05). The use of the stepwise method, adding GSRS-SI and UPDRS III scores to the BDI predictor, improved the model (R2 increased from 0.454 to 0.574). The investigation of GSRS domain's influence revealed that PDQ-39 SI had a significant correlation with almost all of them, but the regression analysis showed significant QoL impacts of only two factors: constipation and abdominal pain (β = 0.288, p < 0.01 and β = 0.243, p < 0.05 accordingly). Conclusions Our results suggest a considerable negative influence of depression and gastrointestinal dysfunction (especially constipation and abdominal pain) on QoL of patients with PD. Their impact on QoL in patients with I-III H&Y stages of PD is more significant than that of motor symptoms. Therefore, the correction of depression and gastrointestinal dysfunction should be prioritized in PD therapy.
Phylogeny, biogeography and classification of Teletisoptera (Blattaria: Isoptera)

Termites are social cockroaches distributed throughout warm temperate and tropical ecosystems. The ancestor of modern termites roamed the earth during the early Cretaceous, suggesting that both vicariance and overseas dispersal may have shaped the distribution of early diverging termites. We investigate the historical biogeography of three early diverging termite families –Stolotermitidae, Hodotermitidae and Archotermopsidae (clade Teletisoptera) – using the nuclear rRNA genes and mitochondrial genomes of 27 samples. Our analyses confirm the monophyly of Teletisoptera, with Stolotermitidae diverging from Hodotermitidae + Archotermopsidae approximately 100 Ma. Although Hodotermitidae are monophyletic, our results demonstrate the paraphyly of Archotermopsidae. Phylogenetic analyses indicate that the timing of divergence among the main lineages of Hodotermitidae + Archotermopsidae are compatible with vicariance. In the Stolotermitidae, however, the common ancestors of modern Porotermes Hagen and Stolotermes Hagen are roughly as old as 20 and 35 Ma, respectively, indicating that the presence of these genera in South America, Africa and Australia involved over‐water dispersals. Overall, our results suggest that early diverging termite lineages acquired their current distribution through a combination of over‐water dispersals and dispersal via land bridges. We clarify the classification by resolving the paraphyly of Archotermopsidae, restricting the family to Archotermopsis Desneux and Zootermopsis Emerson and elevating Hodotermopsinae (Hodotermopsis Holmgren) as Hodotermopsidae (status novum).
Interactions between the soil bacterial community assembly and gene regulation in salt‐sensitive and salt‐tolerant sweet sorghum cultivars

Complex bacterial communities in the rhizosphere play a crucial role in plant growth and stress tolerance. These communities vary across cultivars and external environments. However, the influences of salt stress on the structural composition of bacterial microbiome and gene expression of salt‐sensitive and salt‐tolerant sweet sorghum (Sorghum bicolor L. Moench) cultivars have not been studied sufficiently. Here, we employed a combination of 16S rRNA gene profiling and RNA‐seq analysis to characterize changes in root‐associated microbiomes and determine differentially expressed genes (DEG) in the roots of salt‐tolerant M‐81E and salt‐sensitive 'Roma' var. sweet sorghum cultivars under soil conditions with/without salinity. Results revealed that the two contrasting sweet sorghum genotypes selectively filtered and recruited distinct root microbiota in response to salt stress. M‐81E‐enriched bacterial taxa were more diverse and exhibited a higher abundance of metabolic functions than Roma‐enriched taxa. M‐81E‐associated bacterial co‐occurrence networks were more complex and harboured more positive links than Roma‐associated bacterial networks. Furthermore, nine DEG were identified as core salt‐responsive genes and were central to the salt tolerance of sweet sorghum. Correlation analysis revealed that the expression of HSP70, a molecular chaperone, is linked to the recruitment of numerous M‐81E‐enriched bacteria; their relationship needs further exploration. The study supplements the comprehension of the potential role of host–microbe interactions in the response of sweet sorghum to salt stress.

A numerical analysis on forming limits during spiral and concentric single point incremental forming

Sheet metal forming is one of the major manufacturing industries, which are building numerous parts for aerospace, automotive and medical industry. Due to the high demand in vehicle industry and environmental regulations on less fuel consumption on other hand, researchers are innovating new methods to build these parts with energy efficient sheet metal forming process instead of conventionally used punch and die to form the parts to achieve the lightweight parts. One of the most recognized manufacturing process in this category is Single Point Incremental Forming (SPIF). SPIF is the die-less sheet metal forming process in which the single point tool incrementally forces any single point of sheet metal at any process time to plastic deformation zone. In the present work, finite element method (FEM) is applied to analyze the forming limits of high strength low alloy steel formed by single point incremental forming (SPIF) by spiral and concentric tool path. SPIF numerical simulations were model with 24 and 29 mm cup depth, and the results were compare with Nakajima results obtained by experiments and FEM. It was found that the cup formed with Nakajima tool failed at 24 mm while cups formed by SPIF surpassed the limit for both depths with both profiles. It was also notice that the strain achieved in concentric profile are lower than that in spiral profile.
Comparison of Measurement Techniques for Evaluating the Pressure Dependence of the Viscosity

Abstract The different methods that can be used for measuring the effect of a hydrostatic pressure on the viscosity of polymer melts are evaluated. A linear low-density polyethylene is chosen as test material, as it can be expected to have a small pressure dependency. Special attention is given to methods employing capillary rheometry, as these methods yield a range of shear rates and pressures that are typically encountered under polymer processing conditions. The accuracy of the different techniques is evaluated considering also the complexity of the experimental devices. First it is investigated to which extent standard capillary rheometry can be used to extract information about the pressure dependency of the viscosity. Secondly, it is shown how the accuracy can be greatly increased by the simple addition of a pressure chamber below the exit of the capillary, with a needle valve to regulate the back pressure. The results from this device are compared with those from a more robust method using a pressurized double piston rheometer and with literature data. The experimental values for the pressure coefficient of the viscosity will also be compared with those predicted from PVT data using Utracki's method.
FDI: Hot or Cold Money? The Behaviour of Sectoral FDI Inflows and Outflows Over Periods of Growth Accelerations and Decelerations

The economic crisis caused by the COVID-19 pandemic invokes questions about a possible prolonged economic deceleration. In this article, we study the impact of output growth accelerations and decelerations, as per the definition of Arbache and Page (2007, More growth or fewer collapses? A new look at long run growth in Sub-Saharan Africa [Working Paper 4384]) and Conceicao and Kim (2010, The asymmetric impact of growth fluctuation on human development: Evidence from correlates of growth decelerations and accelerations. Mimeo), on sector-level foreign direct investment (FDI) inflows and outflows for a group of 34 OECD countries in the period 1995–2019. The results show that Finance services FDI and transport services FDI inflows are countercyclical, while manufacturing FDI outflows are procyclical. Transport services FDI outflows are countercyclical, and the most significant determinant of both FDI inflows and outflows is the control of corruption, respectively, in the host and home countries.
