Stability analysis of multiple solutions in case of a stretched nanofluid flow obeying Corcione's correlation: An extended Darcy model

The bi‐dimensional flow of a Fe3O4 ‐water nanofluid perfusing a porous medium has been considered for investigation. The porous space is in contact with a constantly heated sheet stretching at a linear rate. To simulate the nanofluid flow through the pores, an extended Darcy model due to Brinkman and Forchheimer is utilized considering porosity and permeability effects in a convective environment. Corcione's model for effective dynamic viscosity of the nanoparticle mixture is exploited to deduce the effects of nanoparticle size on the flow. Multiple solutions to governing equations are obtained by availing the optimal homotopy asymptotic scheme and discussed for emerging parameters. A unique stable solution is determined availing a stability analysis approach. The heat movement rate is found to be increasing with the reduced nanoparticle size and the enhanced porosity of porous space.
Growth bioestimulant in marandu grass cultivated in the amazon biome

This study aimed to evaluate the effects of a biostimulant on the morphogenesis, structure, productivity, and chemical composition of Urochloa brizantha cv. Marandu, managed under two nitrogen fertilization levels. Collections were carried out during the dry (June to September) and the rainy season (September to April). The experimental area was divided into 48 plots of 8 m2 each, using a randomized block design in a 4 × 2 factorial arrangement (0, 1, 2, and 3 L ha−1 of biostimulant × 50 and 150 kg N ha−1 year−1), and subdivided over time into dry and rainy seasons. Treatments were applied in a single dose. An interaction was observed between biostimulant and nitrogen fertilization for the total forage dry matter production and daily forage dry matter production, in which an increase of 30.1 and 25.3% was observed in the total dry matter production and 33.7 and 27.6% in the daily dry matter production when using 1 and 2 L ha−1 of biostimulant, respectively, compared to the non-application of biostimulant and with fertilization of 50 kg N ha−1 year−1. The leaf life-span showed a triple interaction (biostimulant × nitrogen fertilization × season), and a decomposition of the interaction showed that the fertilization of 150 kg N ha−1 year−1 provided a shorter leaf life-span during the dry season, with no difference for the other combinations of factors. No interactions were found for the chemical-bromatological composition, with no differences for the biostimulant application. Biostimulant doses of 1 and 2 L ha−1 increase the dry matter production per hectare in the nitrogen fertilization of 50 kg N ha−1 year−1, but its action is not effective with the highest nitrogen fertilization (150 kg N ha−1 year−1).
Reversal Returns and Expected Returns from Liquidity Provision: Evidence from Emerging Markets

Abstract In this study, we document, for a number of emerging markets, that positive returns can be obtained using a short-term reversal strategy. These returns are higher for small and illiquid firms, and highest for more volatile firms. Overall, the reversal strategy-based alphas are significant when accessed through different asset pricing models. Our results provide, however, an important unexplored explanation; the reversal return is higher, irrespective of firm characteristics, when market volatility is high, and pronounced for the stocks that witness higher active investor exits. These findings reconcile with the notion that the reversal returns proxy the expected returns from liquidity provision in adverse times.
Mediating role of guest’s attitude toward the impact of UGC benefits on purchase intention of restaurants; Extending social action and control theories

ABSTRACT The User-Generated Content (UGC) like videos, text, images, experience that has been uploaded by the earlier users of a product on an online platform plays an important role in sales of the restaurants. On this aspect, the current paper investigated the role of mediation in the impact of UGC benefits on Purchase Intention of Restaurants across the Kashmir division of Jammu and Kashmir, India, to determine whether a guest’s attitude acts as mediation in between UGC benefits and Purchase Intention of Restaurants or not. A survey instrument was administered to 400 tourists/guests who visited hotel restaurants, out of which a total of 330 responses was judged as usable. The data were analyzed using Structural Equation Modeling (SEM) and other descriptive techniques. Also, the different theories like Social Action Theory and Social Control Theory were validated, which proved the results of this study are consistent with these theories, i.e., SAT, and SCT. This study also highlights that there is an impact on guests’ attitude in the relationship of UGC benefits and Purchase Intention of restaurants.
Flexible parametric modeling of survival from age at death data: A mixed linear regression framework

Correspondence Etienne Rouby, Centre d'études Biologiques de Chizé, UMR 7372, Villiersen-Bois, France. Email: etienne.rouby@univ-lr.fr Abstract Many long-lived vertebrate species are under threat in the Anthropocene, but their conservation is hampered by a lack of demographic information to assess population long-term viability. When longitudinal studies (e.g., Capture-MarkRecapture design) are not feasible, the only available data may be cross-sectional, for example, stranding for marine mammals. Survival analysis deals with age at death (i.e., time to event) data and allows to estimate survivorship and hazard rates assuming that the cross-sectional sample is representative. Accommodating a bathtub-shaped hazard, as expected in wild populations, was historically difficult and required specific models. We identified a simple linear regression model with individual frailty that can fit a bathtub-shaped hazard, take into account covariates, allow goodness-of-fit assessments and give accurate estimates of survivorship in realistic settings. We first conducted a Monte Carlo study and simulated age at death data to assess the accuracy of estimates with respect to sample size. Secondly, we applied this framework on a handful of case studies from published studies on marine mammals, a group with many threatened and data-deficient species. We found that our framework is flexible and accurate to estimate survivorship with a sample size of 300. This approach is promising for obtaining important demographic information on data-poor species.
Diagnostic performance of ultrasonography-guided core-needle biopsy according to MRI LI-RADS diagnostic categories

Purpose According to the American Association for the Study of Liver Diseases (AASLD) guidelines, biopsy is a diagnostic option for focal hepatic lesions depending on the Liver Imaging Reporting and Data System (LI-RADS) category. We evaluated the diagnostic performance of ultrasonography-guided core-needle biopsy (CNB) according to LI-RADS categories. Methods A total of 145 High-risk patients for hepatocellular carcinoma (HCC) who underwent magnetic resonance imaging (MRI) followed by CNB for a focal hepatic lesion preoperatively were retrospectively enrolled. Focal hepatic lesions on MRI were evaluated according to LI-RADS version 2018. Pathologic results were categorized into HCC, non-HCC malignancies, and benignity. The categorization was defined as correct when the CNB pathology and surgical pathology reports were identical. Nondiagnostic results were defined as inadequate CNB pathology findings for a specific diagnosis. The proportion of correct categorizations was calculated for each LI-RADS category, excluding nondiagnostic results. Results After excluding 16 nondiagnostic results, 131 lesions were analyzed (45 LR-5, 24 LR-4, 4 LR-3, and 58 LR-M). All LR-5 lesions were HCC, and CNB correctly categorized 97.8% (44/45) of LR-5 lesions. CNB correctly categorized all 24 LR-4 lesions, 16.7% (4/24) of which were non-HCC malignancies. All LR-M lesions were malignant, and 62.1% (36/58) were non-HCC malignancies. CNB correctly categorized 93.1% (54/58) of LR-M lesions, and 12.5% (3/24) of lesions with CNB results of HCC were confirmed as non-HCC malignancies. Conclusion In agreement with AASLD guidelines, CNB could be helpful for LR-4 lesions, but is unnecessary for LR-5 lesions. In LR-M lesions, CNB results of HCC did not exclude non-HCC malignancy.
Examining effects of surfactants on particle clearance rate and capture efficiency of the blue mussel Mytilus edulis

Suspension-feeding bivalve molluscs perform important ecological roles by coupling pelagic and benthic systems during their feeding activities. Particle capture, and thus feeding, is dependent on particle encounter and retention on the gill filaments, with several factors influencing this process. Over the past 30 yr, different types of synthetic microspheres have been used to examine aspects of particle capture and ingestion by bivalves. Critics of this work have posited that manufactured particles may contain surfactants, chemicals commonly used in manufacturing to reduce surface tension, that could produce spurious capture and ingestion rates. The goal of this work was to experimentally assess whether the presence of different types of surfactants on manufactured polystyrene particles can result in instantaneous effects on particle capture by the blue mussel Mytilus edulis. The effects of 3 different types of common surfactants (sodium dodecyl sulfate, benzalkonium chloride, Triton-X) on clearance rates (CR) and capture efficiencies (CE) were tested. Results indicated that none of the surfactant treatments had an effect on CR. Treatment with one of the surfactants (Triton-X) significantly lowered CE for 3 μm sized spheres compared to the control spheres (Milli-Q treated). None of the other tested surfactants significantly affected CE when compared to the control treatment. These data add to an understanding of particle handling by bivalves, and suggest that concentrations of surfactants found on commercially available microspheres used for experiments or found in the environment have little immediate effect on feeding processes.
Understanding Hydrological Sensitivities Induced by Various Forcing Agents with a Climate Model

The apparent hydrological sensitivity, defined as the globalmean precipitation change per increase of the global-mean temperature, is investigated for scenarios induced by different forcing agents. Simulations with a climate model driven individually by four different climate forcers, i.e. sulfate, black carbon, solar insolation and carbon dioxide (CO2), are analyzed in the context of energy balance controls on global precipitation to explore how different forcing agents perturb different energy components grouped into fast and slow responses. Similarities and differences among the forcing agents are found in ingredients of the tendency contributing to the hydrological sensitivity from various energy budget components. Specifically, the sulfate and solar forcings induce the hydrological sensitivity of ~2.5%K due to the slow response of radiative cooling whereas the black carbon induces a significantly negative hydrological sensitivity (~ −6.0%K) due to the strong atmospheric heating. The CO2-induced hydrological sensitivity is found in between (~1.2%K) as a result from the slow response of radiative cooling and its partial compensation by the atmospheric heating. The findings provide a quantitative basis for interpreting climatic changes of global precipitation driven by a mixture of various natural and anthropogenic forcings. (Citation: Suzuki, K., and T. Takemura, 2020: Understanding hydrological sensitivities induced by various forcing agents with a climate model. SOLA, 16, 240−245, doi:10.2151/sola.2020-040.)
From the fatty acid content perspective, is it healthier to eat a hindquarter or a forequarter cut? Angus steers in pasture or concentrate systems

ABSTRACT In this study, Biceps femoris (BF) and Triceps brachii (TB) of Aberdeen Angus steers, from the hindquarter and forequarter, respectively, were compared from their fatty acid composition, lipid health, and lipid enzyme activity indices points of view. For this, ten animals were produced in a pasture system and ten were finished in a concentrate-based system. TB presented a significantly higher intramuscular fat, saturated C14:0, C14:1, C16:1, CLA, and MUFA content. BF presented a significantly higher LA, ARA, EPA, DPA, DHA, PUFA, total n-6, and n-3 content, and a significantly higher PUFA/SFA ratio. Significant differences between muscles were found regarding lipid enzyme activity indices, but not concerning atherogenic and thrombogenic indices. Also, meat from different feeding systems was compared, where meat from pasture presented a better fatty acid composition regarding cardiovascular health aspects. In conclusion, BF presented a better composition in the most nutritionally relevant fatty acids, with exception of CLA.
Students’ experience of pervasive skills acquired through sponsored projects in an undergraduate accounting degree

An accounting graduate should not only possess technical knowledge, but also core competencies and pervasive skills necessary to meet the needs of employers and society as a whole. This study is centred on the undergraduate accounting programme of a South African university where several sponsored projects are offered to develop these skills. An exploratory design using purposive sampling was used to gain insights into the perceptions of students on whether these skills were developed throughout their degree. It was found that the students perceived the projects to have developed their critical thinking and problem-solving skills, promoted their ethical awareness and enhanced their communication skills. Students further gained a better understanding of the role of an accountant through their participation in the sponsored projects and found them effective learning experiences. The challenges reported by students were the social aspect of the projects and the ability to work successfully in a team.
Have Europeans Grown Tired of Democracy ? New Evidence from 18 Consolidated Democracies , 1981-2018

Democracies without democrats are not sustainable. Yet, recent studies argue that Western citizens are turning their backs on the system of self-governance, thereby eroding the societal foundations of consolidated democracies. We contribute to discussions about citizen support of democracy by 1) analyzing new cross-national survey data in 18 European countries that enable assessing the temporal and geographical generalizability of previous findings; 2) disentangling age-, cohort-, and period effects, thereby aligning the analytical methods with the theoretical arguments; 3) transparently reporting the entire evidence derived from pre-registered analyses to avoid cherrypicked findings. Our findings show that citizens of consolidated democracies continue to endorse self-governance. Yet, in some but not all countries, there is evidence for a growing number of ‘democrats in name only’, particularly among the young generation. These findings suggest a second phase in research on democratic fatigue that broadens the analytical scope for the multi-faceted nature of democratic support.
Organic photodetectors based on supramolecular nanostructures

Self‐assembly of semiconducting (macro)molecules enables the development of materials with tailored‐made properties which could be used as active components for optoelectronics applications. Supramolecular nanostructures combine the merits of soft matter and crystalline materials: They are flexible yet highly crystalline, and they can be processed with low‐cost solution methods. Photodetectors are devices capable to convert a light input into an electrical signal. To achieve high photoresponse, the photogenerated charge carriers should be transported efficiently through the self‐assembled nanostructures to reach the electrodes; this can be guaranteed via optimal π–electron overlapping between adjacent conjugated molecules. Moreover, because of the high surface‐to‐bulk ratio, supramolecular nanostructures are prone to enhance exciton dissociation. These qualities make supramolecular nanostructures perfect platforms for photoelectric conversion. This review highlights the most enlightening recent strategies developed for the fabrication of high‐performance photodetectors based on supramolecular nanostructures. We introduce the key figure‐of‐merit parameters and working mechanisms of organic photodetectors based on single components and p–n heterojunctions. In particular, we describe new methods to devise unprecedented planar and vertical devices to ultimately realize highly integrated and flexible photodetectors. The incorporation of ordered mesoscopic supramolecular nanostructures into macroscopic optoelectronic devices will offer great promise for the next generation of multifunctional and multiresponsive devices.
Construction of Three-Dimensional Pore Network in Bulk Grain

In order to construct a 3D pore network reflecting the real pore structure of bulk grain, a series of 2D section images are obtained and used to reconstruct 3D images using MATLAB. The parameters of the 3D pore network are extracted by the maximal ball method. A stochastic 3D pore network with a random size is generated, but some throats are lost in generation. The parameter deviation between the original model and the generated model decreases with an increase in volume. There is almost no deviation when the space size is up to meter level. The image resolution of 0.5 mm is enough to extract parameters of the bulk grain.
Does a Science-Oriented Worldview Entail Unbelief?

Endorsement of science is often associated with non-religiosity and lack of supernatural belief. However, the relevance of science for worldviews might also relate to the cultural context and/or personal investment in science. This study investigates the following question: Is endorsement of worldview components of science associated with unbelief among science-oriented respondents? Here, worldview components refer to science providing 1) a sense of meaning, 2) moral standards, and 3) literal or symbolic continuity after death. 387 Finnish adults recruited via pro-research organizations were included in the analysis. The results suggest that self-reported worldview functions of science are associated with unbelief also among science-oriented individuals. These findings lend support to the belief replacement hypothesis, which suggests that secular worldviews such as belief in science are of particular importance for unbelievers. However, the effect sizes are small and also other God belief groups endorse the significance of science for e.g., meaning in life.
Strain engineering of topological properties in lead‐salt semiconductors

Rock‐salt chalcogenide SnTe represents the simplest realization of a topological insulator where a crystal symmetry allows for the appearance of surface metallic states. Here, we theoretically predict that strain, as realized in thin films grown on (001) substrates, may induce a transition to a topological crystalline insulating phase in related lead‐salt chalcogenides. Furthermore, relevant topological properties of the surface states, such as the location of the Dirac cones on the surface Brillouin zone or the decay length of edge states, appear to be tunable with strain, with potential implications for technological devices benefiting from those additional degrees of freedom.

Experiences of Family Caregivers’ Involvement in Treatment Related- Decision-Making in Triadic Health Encounters

Background: In the last decade, the role of family caregivers has started to be highlighted, in response to the limits of shared decision-making models focusing only on patient-physician interactions (Kristopher.2017). Some patients are unsure of the value of their own decision and wanted to leave the decision to others (Olsson, et al., 2016). Purpose: To explore the experiences of family caregiver in health decision-making for patients with chronic diseases.Study Design: A descriptive qualitative approach was used.Methods: A purposive sample of (15) family caregiver for patients with chronic diseases were interviewed.Data were generated through phone messages voice records over a period of 2 months (March & April 2020). Data were analyzed using a five – step technique proposed by Giorgi (1985). Results: fifteen caregivers; males (n= 2), females (n= 13). Average of age = 40 years old. Findings revealed three major themes related to family caregivers experiences in health decision-making for patients with chronic diseases: 1) The patient has the right to decide about his health, 2) Health care providers know better, and 3) Roles of FCs in decision making process.Conclusion: The vital role of the FMs in taking decisions for patients with chronic diseases is well recognized by health care providers. Continuous systematic assessment of family members’ preferences and needs is crucial to provide the needed support for their patients in decision-making.
The characteristic computed tomography findings of pulmonary B-cell non-Hodgkin's lymphoma and their role in predicting patient survival.

Background To assess the value of characteristic computed tomography (CT) findings in predicting the survival of patients with pulmonary B-cell non-Hodgkin's lymphoma (NHL). Methods Eighty-four patients who were histopathologically confirmed with pulmonary B-cell NHL between 2004 and 2018 were retrospectively enrolled. All patients underwent chest CT scan at the time of initial diagnosis in our hospital. Characteristic CT findings and clinicopathological features of the patients were analyzed, and Cox regression models were used to determine the relationship of CT findings with overall survival (OS) and progression-free survival (PFS). Results Air bronchogram occurred more frequently in patients with early-stage disease, primary pulmonary lymphoma (PPL) and the indolent histological type of lymphoma than in patients with advanced-stage disease, secondary pulmonary lymphoma (SPL), and the aggressive histological type (all P<0.05). The halo sign was observed most in the SPL group (19/48, 40%; P=0.004), while the presence of cross-lobe sign was higher in patients with PPL (13/36, 36%; P=0.010). Pleural involvement and hilar/mediastinal lymphadenopathy were observed more in patients with SPL and the aggressive histological type (33/48 and 27/48; 31/46 and 26/46, respectively; all P<0.05). Survival analyses showed that the number of lung lesions, cross-lobe sign, and pleural involvement were independent prognostic factors for PFS, while the halo sign and pleural involvement were significantly correlated with OS (all P<0.05). More aggressive, advanced-stage cases and male patients showed worse outcomes. Conclusions The halo sign and pleural involvement are independent prognostic factors for OS, while the number of lung lesions, cross-lobe sign, and pleural involvement are correlated with PFS.
