A pesquisa em acervos e o remanejamento da crítica
Authors: Cury Maria Zilda Ferreira
Published: April 2024

The research in archives, comprehending the recovery of the so called primary sources, proves itself important for the process of re-thinking the role of critics in the revision of the history of literature. Turning its attention to that which is fragmentary, corrected, and incomplete, it becomes a metaphor for the literary text, and for a more open attitude of the contemporary literary criticism.
Antes do começo dos começos
Authors: Willemart Philippe
Published: April 2024

The "Chronicle of Nuremberg" of 1493, that narrates the origin of the universe, reveals a God creating a world that is still incomplete. Establishing a link between this conception of creation quoted in "Genèses du roman contemporain" (1993) and "Le manuscrit inachevé. Écriture, Création, Communication" (1986), it is emphasized the hesitation of some writers in accepting the contingency of their works and the necessity of the genetician in taking into account the corrected fragments or the versions not published, not as a variant, but as a step toward a different logic of the text.

O artigo investiga possíveis relações entre a criança e o texto que pos­sam estar envolvidas durante esse processo de produção. O objeto de estu­do é a narrativa ficcional de crianças em idade pré-escolar que estão começando a escrever alfabeticamente suas primeiras histórias. A metodologia de pesquisa adotada permitiu algum tipo de acesso ao modo como a criança relaciona-se com o texto, para que a análise não ficasse restnta àquilo que ficou registrado no papel. É feita uma aproximação desse procedimento metodológico às pesquisas em Crítica Genética.

BACKGROUND:

The impact of routine clinic use of patient-reported outcome (PRO) measures on clinical outcomes in patients with heart failure (HF) has not been well-characterized. We tested if clinic-based use of a disease-specific PRO improves patient-reported quality of life at 1 year.

METHODS:

The PRO-HF trial (Patient-Reported Outcome Measurement in Heart Failure Clinic) was an open-label, parallel, patient-level randomized clinical trial of routine PRO assessment or usual care at an academic HF clinic between August 30, 2021, and June 30, 2022, with 1 year of follow-up. In the PRO assessment arm, participants completed the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) at each HF clinic visit, and results were shared with their treating clinician. The usual care arm completed the KCCQ-12 at randomization and 1 year later, which was not shared with the treating clinician. The primary outcome was the KCCQ-12 overall summary score (OSS) between 12 and 15 months after randomization. Secondary outcomes included domains of the KCCQ-12, hospitalization and emergency department visit rates, HF medication therapy, clinic visit frequency, and testing rates.

RESULTS:

Across 17 clinicians, 1248 participants were enrolled and randomized to PRO assessment (n=624) or usual care (n=624). The median age was 63.9 years (interquartile range [IQR], 51.8–72.8), 38.9% were women, and the median baseline KCCQ-12 OSS was 82.3 (IQR, 58.3–94.8). Final KCCQ-12 (available in 87.9% of the PRO arm and 85.1% in usual care;
P
=0.16) median OSS were 87.5 (IQR, 68.8–96.9) in the PRO arm and 87.6 (IQR, 69.7–96.9) in the usual care arm with a baseline-adjusted mean difference of 0.2 ([95% CI, −1.7 to 2.0];
P
=0.85). The results were consistent across prespecified subgroups. A post hoc analysis demonstrated a significant interaction with greater benefit among participants with a baseline KCCQ-12 OSS of 60 to 80 but not in less or more symptomatic participants. No significant differences were found in 1-year mortality, hospitalizations, emergency department visits, medication therapy, clinic follow-up, or testing rates between arms.

CONCLUSIONS:

Routine PRO assessment in HF clinic visits did not impact patient-reported quality of life or other clinical outcomes. Alternate strategies and settings for embedding PROs into routine clinical care should be tested.

The Politics and Aesthetics of Liberation: Revolution and Its Aftermath in Contemporary Artistic Practice from and about Lusophone Africa
Authors: Balona de Oliveira Ana
Published: April 2024

This essay explores the ways in which artistic practices have revisited histories and memories of anti-colonial struggle, socialist revolution, and decolonization in Mozambique, Angola, Guinea-Bissau, and Portugal, while also addressing apartheid South Africa and the global Cold War. The cartography drawn here follows the histories and geographies of anti-colonial and anti-apartheid friendship without losing sight of several forms of imperialism, old and new. This essay examines the archival and historiographical potential of contemporary art in remembering histories of revolution and decolonization, notably those pertaining to cultural production and especially film, in the globalized, neoliberal present. My case studies are distinct but related works by Ângela Ferreira (Mozambique, 1958), Filipa César (Portugal, 1975), and Kiluanji Kia Henda (Angola, 1979), which include installation, video, photography, and performance for the camera. What sort of insights do the archival imaginations of pasts, presents and futures at play in these works offer? And how far can the ethics and politics of their aesthetics go?

An unusual species of the genus Pseudohalmyrapseudes Larsen & Hansknecht, 2004 (Tanaidacea: Parapseudidae) from the mangrove swamps of the Cần Giờ Biosphere Reserve, South Vietnam
Authors: MARIN IVAN , PALATOV DMITRY , THỊNH NGUYỄN VĂN
Published: April 2024

The article describes a new species of the genus Pseudohalmyrapseudes (Tanaidacea: Parapseudidae: Parapseudinae) found in the cut part of the deep channel of the Cần Giờ Mangrove Biosphere Reserve in South Vietnam. The new species shares morphological features of such parapseudid genera as Pseudohalmyrapseudes including a three- and four-articulated inner ramus of antennule in females and males, respectively, the triangular shape of fixed finger, and the presence of basal tooth on dactylus of cheliped in males. From Halmyrapseudes it is distinguished by the well-marked outer serration on the lobe of labium and the presence of relatively small blunt ventral tooth on carpus of the male cheliped. At the same time, it can be easily separated from any species of these genera by the shape of male cheliped, especially by the triangular shape of fixed finger and the presence of basal process tooth on dactylus, and the absence of plumose ventral setae on merus, carpus and propodus of pereopod VI. The new species is also unusual within the genus Pseudohalmyrapseudes in terms of habitat, as it lives in mangrove swamps rather than freshwater environments, known for congeners, and its distribution area, representing the first species from the Asian region. Based on the calculated density (124±17 inds/m2) and the trophic niche determined by the analysis of stable isotopes δ13C/δ15N, the studied species is considered among important primary consumers (C1), most likely feeding on the leaves of the mangrove Rhizophora apiculata in the studied lagoon.

Published: April 2024

Pariolius is a heptapterid genus represented by P. armillatus that is distributed along the upper Amazon River basin. A taxonomic integrative revision of Pariolius from Colombian Rivers revealed two new species. Several approaches as morphological, morphometric, meristic, osteology and molecular data were used to distinguish between Pariolius species. The two new species are distinguished from congeners by the caudal-fin shape and numbers of rays, colorations patterns and several morphometric characters. The two new species of Pariolius are restricted to tributaries of the Upper Orinoco and Upper Negro rivers in Colombia.
Bouchetaria (Gastropoda: Cypraeidae), a new genus for the Riddle cowry, B. aenigma (Lorenz 2002), from the deep waters of the Mozambique Channel
Authors: CASTELIN MAGALIE , LORENZ FELIX
Published: April 2024

Based on molecular and conchological features, a new genus, Bouchetaria, is proposed for the Cypraeidae species Nesiocypraea aenigma Lorenz 2002. Molecular analysis of cox1 and 16S genes places Bouchetaria within a monophyletic group—composed of the genera Propustularia, Nesiocypraea, Ipsa, Perisserosa, Cryptocypraea, and Nucleolaria—appearing as the sister group to all other living Cypraeidae. This group corresponds to the Erosariinae (sensu Lorenz & Hubert, 1993). The cox1 pairwise genetic distances between Bouchetaria aenigma and its closest taxa, Propustularia surinamensis and Nesiocypraea teramachii correspond to 15% and 17% difference, respectively. Morphologically, the sole species of the genus Bouchetaria differs from other Erosariinae genera by the near absence of darker color pattern, and denser and longer dentition, which extends onto the labrum and towards the base, where it forms branches. These morphological characters justify the edification of a new genus: Bouchetaria. Consistent with its multispiral protoconch, Bouchetaria aenigma has a fairly wide range in the deep-sea of the Mozambique Channel, from the northern coast of Kwa-Zulu Natal, South Africa, to the northern tip of Madagascar and the Glorioso Islands.

In this study, we described the last instar larva of Angelagrion nathaliae Lencioni, 2008, the first one described for this genus, collected in Inconfidentes and Uberlândia municipalities, Minas Gerais state, Brazil. We compared the diagnostic characters of A. nathaliae with some species of Telebasis Selys, 1865. Despite some similarities with Telebasis larvae, the larva of A. nathaliae can be distinguished from the family by a combination of characters of the mouthparts and gills.
The Ideological Functions of the Disclaim Resources in Press Conferences
Authors: Lin Yansong , Yang Yang
Published: April 2024

In Critical Discourse Analysis, appraisal system has been of ideological interest because it concerns the language expression closely related to values. When answering questions in press conference, many appraisal resources are used by speakers to express their own stances on important issues and persuade the journalists and the public. This article focuses on the disclaim resources within the appraisal framework, and analyzes their ideological functions in press conferences. Specifically, using a corpus of 100 transcriptions of press conferences as data, this study investigates the discursive function of disclaim and stance-taking realized by disclaim in press conferences from an ideological dimension. It can be found that deny is always widely employed together with counter to reject and replace the point of view, and thus realize the discourse function of counter-expectancy and information modification. Through disclaim, such evaluative stances, including but not limited to reminding, warning, dissuading, prohibiting, questioning, opposing, refusing and criticizing are expressed. The stance-taking realized by disclaim could help the speaker to show his or her positions in a more covert way, so as to establish and maintain power relationships. Therefore, the employment of disclaim in press conferences really carries strong ideological implications and the thorough analysis of the disclaim resources could provide some implications for Critical Discourse Analysis. Besides, from the study we can see that spokesman could use a lot of language resources to emphasize his or her own stances, and thus to convince the audience. Therefore, this study could provide some implications for spokesman of press conferences, especially for government spokesman to effectively communicate with the audience and achieve a more harmonious communication.

Suction/Injection Influence on Electrical MHD Nano-Fluid on a Nonlinear Radiative Flow Over a Stretching Sheet
Authors: Adem Gossaye Aliy
Published: April 2024

The current communication’s goal is to look at how a radiative electrical MHD Casson nanofluid moves through a stretched sheet while being affected by nonlinear thermal radiation and suction/injection. The controlling equations incorporate a temperature and concentration parameter
that is modified viscosity/thermal conductivity dependent in order to enrich the blood flow. By using similarity transformations, the system of PDEs is converted to an ODE, which is then numerically solved using the well-known fourth-order Runge-Kutta integration strategy based on the shooting
method. The impacts of operating parameters on velocity, temperature and concentration profiles were explained and examined through tables and graphs. Temperature and concentration are increased as the injection (S < 0) increases. However, they show decrement when the suction (S
> 0) increases.
Study of Convection Under Hall Current Generation in a Rivlin-Erickson Nanofluid
Authors: Bishnoi Jaimala , Kumar Shubham
Published: April 2024

The major objective of the present study is to recognize the passion of parameters to fill the gaps between the experimental solutions and theoretical solutions of a Rivlin-Erickson nanofluid confined between two horizontal infinite free-free boundaries. The physical system is portrayed by Brownian motion and thermophoresis of nanoparticles, an external uniform transverse magnetic field, and effective Hall currents. Furthermore, constant temperatures and no flux of nanoparticles at the two boundaries have also been considered. To formulate the problem normal mode technique is employed and for mathematical analysis, Galerkin-type weighted residual method is implemented. Thus, a linear dispersion equation is obtained and the stability or instability stipulations are illustrated graphically displaying the impacts of several parameters entering the problem. It is found that in the case of stationary convection, the nanofluid Lewis number, concentration Rayleigh number, modified diffusivity ratio, and Hall current are responsible for aggravating the convection while the effect of the magnetic field is stabilizing. The conditional existence of oscillatory convection has been established. Behaviour of the stationary as well as oscillatory convection have been verified for the water alumina nanofluid. Valuable comparisons with the existing studies have been given. It has been observed that the convection in a continuous medium is more stable than it is in a porous medium. Further, in comparison to the regular Rivlin Erikson fluid, the Rivlin Erickson fluid with heavier density nanoparticles supports the convection.
Mixed Convection in a Lid-Driven Cavity Filled with Nanofluids Using Single- and Two-Phase Eulerian Modeling Methods
Authors: Waheed M. A. , Olalekan O. O. , Enweremadu C. C.
Published: April 2024

The numerical simulation of the classical lid-driven cavity problem has been carried out to investigate the suitability of two-phase flow modeling techniques for nanofluids in computational fluid dynamics. The nanofluid investigated comprises water as base fluid and Al2O3
nanoparticles. Three types of the Eulerian-multiphase models, including the Eulerian, mixture, and volume of fluid (VOF) were compared with the single-phase model. The model equations were solved using ANSYS Fluent software for the nanoparticle volume fraction, the Richardson and Reynolds
numbers in the range 0 ≤ ø ≤ 0.10, 10−4 ≤ Ri ≤ 102, and 1 ≤ Re ≤ 1000, respectively at a fixed Grashof number, Gr = 100. The results were compared with that of single-phase nanofluid modeling. There were similarities
in the flow structure and temperature distribution for the single-phase and multi-phase methods when the convection is natural and mixed. However, the Nusselt number computed by the mixture and Eulerian models is higher than that of the single-phase and VOF models under the forced convection
regime, with the percentage deviation from that of the single-phase as high as 10%. So, the three multiphase models are suitable for nanofluid convection problems and give results comparable to the single-phase model, especially under the natural and mixed convection regimes.

Authors: Preetham M. P. , Kumbinarasaiah S.
Published: April 2024

This study examines the magnetohydrodynamic (MHD) steady laminar incompressible viscous flow of a hybrid nanofluid (HNF) in a rotating system among two surfaces where the lower plate is stretchable, and the upper plate is permeable with the effect of thermal radiation and Joule heating
by Fibonacci wavelet series collocation method (FWSCM). The governing nonlinear partial differential equations (PDEs) are transformed into coupled nonlinear ordinary differential equations (ODEs) using appropriate similarity transformations. These ODEs are solved by FWSCM. The accuracy of
FWSCM is validated with the Haar wavelet collocation method (HWCM), Mathematica NDSolve command, and previously available numerical results. The effects of the suction/injection parameter, the volume fraction of the hybrid nanofluid, magnetic parameter, Prandtl number, Reynold’s number,
radiation parameter, and rotation parameter on the flow velocities, heat transfer, and the physical quantities are examined through tables and graphs. It is found that the temperature profile exhibits the same behavior during the suction and injection process when the magnetic and rotation
parameter increases.
Significance of Variability in Liquid Properties on 3D MHD Maxwell Nanofluid Flows Over a Stretching Surface with Heat Generation/Absorption and Chemical Reaction
Authors: Basha Hussain
Published: April 2024

Objective of the current research investigation is linked with advancement in nanotechnology and fluids flow phenomena subject to various fluid models. The model adopted over here is Maxwell–nanofluid model subject to magnetohydrodynamics impact confined within the dimensions
of a bi-directional stretching surface. The boundary is assumed to be convective in the context of thermal state and zero mass flux in the context of nanoparticles. Furthermore, slip condition on velocity and a source of heat generation/absorption is also considered in the flow model. It is
pertinent to mention that base fluid is assumed to be chemically reactive by involving first order chemical reaction term in the governing equation of concentration of nanoparticles. So formulated, highly nonlinear set of governing equations is converted into nonlinear ODEs involving various
parameters including Brownian diffusion, Deborah number, magnetic parameter, Prandtl and Schmidt number, heat generation/absorption and the first order chemical reaction. The ODEs are solved by a semi-analytic technique of OHAM (Optimal Homotopy Analysis Method). The results are plotted graphically.
The obtained findings are compared without available literature in the same direction by assuming special cases on various parameters.

Bioconvection Pumping of Nanofluid Flows in a Curved Conduit with Electromagnetic Fields, Thermal Radiation and Joule Heating
Authors: Noreen S. , Aslam F.
Published: April 2024

This study analyses the electroosmotic transport of Jeffrey nanofluids containing gyrotactic microorganisms in a two-dimensional curved microchannel enduring peristalsis. In the presence of magnetic field, variable properties, viscous dissipation, Ohmic dissipation, thermal radiation,
thermophoresis, and Brownian motion in a wave frame of reference in curvilinear coordinates, the formulation of the problem has been made. The governing equations are solved using Mathematica’s software, yielding numerical solutions. Detailed physical reasoning is used to graphically
depict the consequences of the dimensionless variables involved. It has been observed that mobile microorganisms improve both the efficiency of heat transfer and the stability of nanoparticles. It is observed that the irreversibility rate decreases as the viscoelastic parameter, Darcy number,
and radiation parameter increase. For small values of the curvature parameter, the nanofluid’s axial velocity is not symmetric about the centerline. Increases in the viscous dissipation parameter, Hartmann number, and Joule heating parameter intensify the temperature distribution, while
increases in the radiation parameter have the opposite effect. The nanoparticle concentration decreases as thermophoresis advances and increases as the Brownian motion parameter rises. Electroosmotic phenomenon and magnetic parameter increase the rate of heat and mass transfer along the channel
walls.

Significance of Inclined MHD on Hybrid Nanoliquid Flow in an Annulus Using Modified Buongiorno Model in the Presence of Two Different Heat Sources: Response Surface Methodology
Authors: Thriveni K.
Published: April 2024

In this modern fluid field technology, hybrid nanoliquid are of great interest to researchers because of their thermal properties which provide superior heat transfer improvements compared to nanoliquid. Thus, in this study, the heat and mass transport characteristics in a horizontal
annular duct filled with the water-based Cu–Al2O3 hybrid nanoliquid is analyzed using the modified Buongiorno model (two-phase model). The two different heat sources namely, temperature-related heat source (THS) and exponential space-related heat source (ESHS) are
analyzed in thermal analysis. An inclined magnetism and viscous dissipation aspects are also taken into account. The correlation for effective thermal conductivity and viscosity are modeled by utilizing the experimental work of Corcione. The coupled nonlinear equations were solved numerically
using the finite difference method. Further, the heat transport rate is optimized using the response surface methodology (RSM). The significance of effective parameters on the flow structure, thermal pattern, concentration field, heat and mass transport rate are visualized through two-dimensional
(2D) and three-dimensional (3D) surface plots. It is noticed that the chaotic motion of nanoparticles advances the thickness of the thermal and solutal boundaries. The velocity field has an inverse association with the applied magnetic field and its angle of inclination. The consequence of
the Reynolds number is favorable for the velocity and temperature fields. The heat transport is more dominated by the Reynolds number compared to the chaotic motion of nanoparticles and thermophoretic aspect. Furthermore, the sensitivity of the Nusselt number to the Reynolds number, chaotic
motion of nanoparticles and thermophoretic aspect are always negative.

Published: April 2024

In the current research, fin structures of various shapes, including rectangular profiles and exponentials with thin and thick tips have been taken into account. Here, it has been explored how the thermal performance in unsteady exponential moving porous fin structures is affected by the flow of hybrid nanofluid under convection and radiation circumstances. The hybrid nanofluid is composed of silver (Ag) and graphene (Gr) nanoparticles suspended in pure water as base fluid. In this study, in the place of volume concentration, the masses of the base fluid and the nanoparticles are taken into consideration by employing the Tiwari-Das nanofluid model. The governing partial differential equations (PDE) that are modeled have been nondimensionalized and further solved by using the finite difference method (FDM). The impact of dimensionless parameters on the thermal behavior of the rectangular and exponential fin structures has been demonstrated graphically. It is discovered that the thermal profile increases with time and achieves a stable state after a certain amount of time. Further, an exponential fin with a thick tip performs better than the other two profiles in the process of fin cooling. This study can be a useful analysis in the design of fin structures for practical applications.
Influence of Suction and Injection on Peristaltic Mechanism of a Jeffrey Nanofluid in a Vertical Channel with Complete Slip Effects
Authors: Vijayakumar P. , Hemadri Reddy R.
Published: April 2024

The main goal of the current study is to understand how the peristaltic system of a Jeffrey nanofluid operating in a vertical tube with complete slip properties is influenced by suction and injection. The peristaltic flow was examined by several researchers using various biological
fluid types. The majority of the authors used viscous (Newtonian) fluids to illustrate the peristaltic flow mechanism. Because of its uses in industry, non-Newtonian fluids have attracted a great deal of attention. There are numerous models for non-Newtonian liquids because of the complexity
of fluids. The Jeffrey fluid model is the most straightforward linear model to depict the non-Newtonian fluid characteristics for which it is reasonable to expect that accurate or analytical solutions would eventually be discovered. Nanofluids are innovative substances that have endless applications
in engineering, biology, medicine and other fields. This mathematical model can be used effectively to transport cervical cancer in the tiny blood channels of the cervix. The resulting flow model is then effectively simulated with the appropriate assumptions of a small Reynolds number and
long wavelength. The governing conservation equations are then established. Analytical solutions have been found for, pressure rates per wavelength, temperature, velocity and concentrations of nanoparticles in the resultant flow problem. Using the software WOLFRAM MATHEMATICA, the effects
of all physical parameters on streamline, velocity, temperature, concentration fields, pressure gradient, frictional force and pressure rate are graphically analyzed. We observed in both 2D-plot and 3D-plot that we increasing the slip parameters β1 and β2
lead to increase the velocity profile. By raising the Jeffrey nanofluid parameter, the pressure rise is decreased. With frictional force, the opposite behavior is observed. The effect of suction and injection parameter k on the trapping bolus, which gets greater as k is higher.

Nanofluids are made up of nanoscale particles such as copper, carbides, graphite, and alumina, which help base fluids transmit heat more efficiently. These nanofluids have a broad range of applications in today’s framework of cooling and heating, solar-powered cells, hybrid-powered
engines, new fuel generation, cancer therapy, and pharmaceuticals. This present investigation emphasizes the importance of a specific type of fluid called a hybrid nanofluid, which consists of (Cu and TiO2) nanoparticles suspended in H2O (water). This fluid is subjected
to a combination of several complex phenomena of heat transfer in hybrid nanofluid flow past an infinite orthogonal plate, including velocity slip and Biot number using fractional calculus. The system of governing partial differential equations (PDEs) are transformed into a set of first-order
ordinary differential equations (ODEs) using appropriate mathematical transformations. These equations were then solved numerically using fractional power series method (FPSM). FPSM is a very powerful method in solving fractional differential equations arising from different types of scientific
problems. The study investigated the behaviour of velocity profiles, temperature, skin friction and heat transfer for various values of the parameters involved.The rate of heat transfer decreases with increasing the hybrid nanofluid parameter but it increases with increasing the fractional
order, velocity slip and Biot number Additionally, the skin friction decreases with increasing both the hybrid nanofluid parameter and velocity slip, but it increases with increasing of the fractional order. However, there is no change in skin friction when the Biot number increases. It is
also clear that the velocity increases for increasing both fractional order, velocity slip, it decreases for increasing the nanofluid parameter. The temperature profile rises when both the nanofluid parameter and Biot number increase. Also temperature profile decreases when the values of the
fractional order and slip parameters increase.

In the realm of biotechnology and various biological systems, scientists have made significant contributions in the current decade to the understanding of bioconvection. In this study, a theoretical bioconvection model has been developed to investigate the thermally induced flow of
a magnetized Burger nanofluid over an inclined surface. The analysis incorporates the effects of the Cattaneo-Christov heat and mass flux model. The governing partial differential equations are transformed into a set of nonlinear ordinary differential equations using a suitable similarity
transformation. These equations are then numerically solved using the BVP4C shooting method to provide insights into the impact of key parameters on fluid and flow properties. MATLAB software is employed to generate figures, present numerical values, and illustrate the effects of various fluid
parameters graphically. The findings reveal that the concentration of microbes decreases with an increase in the thermophoretic force and rises with an increasing microbe’s Brownian motion parameter. Moreover, the research has unveiled numerous engineering and industrial applications.
The presented model holds relevance in diverse areas such as industrial-grid engines, electrical engineering, device cooling, nuclear reactors, pharmaceutical science, cancer treatment, biotechnology, mechanical engineering, bioscience, automobiles, medicine, and beyond.

As part research, non-linear thermal radiation is used to learn how magnetic fields affect the incompressible, viscous and conductive flows of non-Newtonian nanofluid flow. The characteristics of this flow are indomitable and tenacious. The momentum equation has been updated to include
the magnetic field and the energy equation has been updated to include thermal radiation. This procedure uses a similar transformation to turn the principal PDE into a regular differential equation. After performing the similarity analysis, the Runge-Kutta (R-K) method can be used together
to solve the related equations. Adjustment equations are applied to each flow variable and analysis marks are plot and interpreted. The profile of velocity, temperature, and concentration is displayed. Table following summarizes the effects of other flow factors studied: skin friction coefficient,
Nusselt number, and Sherwood number. The program code has been validated and excellent concordance between the findings and previously published benchmarks.

A new wavelet-numerical method for solving a system of partial differential equations describing an incompressible bio-convection nanofluid flow in a three-dimensional region close to the stagnation point is the primary focus of this article. Hermite wavelets form the basis of the algorithm.
An assortment of similitude factors is utilized to improve on the overseeing conditions addressing the protection of all out mass, force, nuclear power, nanoparticles, and microorganisms to a bunch of completely connected nonlinear common differential conditions. The most important physical
quantities that have a practical impact on the spread of motile bacteria are presented and analyzed in this paper. During bio-convection, the Prandtl, Lewis, Peclet, Schmidt, and Rayleigh numbers can alter the distribution of moving molecules. The dispersion of microorganisms can be emphatically
affected by the kinds of nanoparticles and by the varieties in the temperature as well as volumetric part of the nanoparticles between the wall and the encompassing liquid. With excellent agreement for coupled nonlinear differential equations in engineering applications, our result demonstrates
how powerful and simple the HWM is for solving these coupled nonlinear ordinary differential equations.

Published: April 2024

The study of hydromagnetic CNTs of Casson fluids in Poiseuille flow has significant implications for various industries and can provide valuable insights into the fundamental properties, such as viscosity and conductivity of these fluids. They can improve the heat transfer properties
of fluids and enhance the overall efficiency of thermal systems and the presence of CNTs can induce a magnetic field in the fluid. The main goal of using carbon nanotubes (CNTs) in Poiseuille flow is to enhance the fluid flow properties, such as viscosity, thermal conductivity, and heat transfer
and the novelty of CNTs in Poiseuille flow lies in their ability to modify the fluid flow properties by altering the structure of the fluid at the nanoscale level. The use of CNTs in Poiseuille flow has gained attention due to their unique mechanical, electrical, and thermal properties. An
analytical approach to the investigation of heat transmission in hydro-magnetic forces of natural convective flow of Casson-fluid in a Poiseuille flow implanted by Darcian regime on Carbon Nanotubes with the impacts of magnetic field, heat generation, diffusion thermo, porosity, radiation
and first order chemical reaction is presented. In this research, dual solutions are introduced for single-wall and multiple-wall carbon nanotubes over velocity and temperature of nanofluid by the application of various physical and they are elaborated via plane curves. The base fluid is considered
for the CNTs as Engine oil. Validity of this model has established by comparing with the available previous literature and is found acceptable agreement with it. In the present study, it is found that the fluctuation in radiation and heat generation plays a significant role in CNTs. It is
known that a rise in the Casson parameter and nanoparticle volume fraction enhances the fluid velocity. It is concluded that, the volume fraction of nanoparticles in Poiseuille flow can have a significant impact on the flow behaviour and properties of the fluid. This study has tremendous feasible
applications in the areas related to biomedical sciences, water purification process, technology of fibers, nano-materials technology, storage of energy and various applications.
Williamson Nanofluid Over A Cone and Wedge: Numerical Modelling of Hydromagnetic Brownian Motion Using the Extended Darcy Model
Authors: Das Bikash , Ahmed Sahin
Published: April 2024

The originality of this experiment lies in examining how the Lorentz force and Fr affect the Williamson fluid as it moves over the cone and wedge, two very different geometries. Along with the modifiable parameters of non-isothermal settings, the effects of Soret and Dufour are also
taken into account. The non-linear equations of conservation are converted into the ordinary differential equations by utilizing appropriate similarity transformations. Finally, solutions to the system of ODEs are obtained by employing a finite difference scheme known as bvp4c in MATLAB. The
relative tolerance of the scheme is set to 10−6 and a grid size of 10−3. The stability and convergence of the scheme have been verified by the grid point stability test. The behaviour of momentum of molecules and their thermal and mass diffusion of the fluid,
and also the velocity–gradient, temperature-gradient, and species-gradient are portrayed explicitly and deliberated in detail for the influence of numerous fluid parameters. It is found that the heat-transmission on the surface of the cone is advanced than the wedge, and the rate of
transmission of heat is supreme for Newtonian fluid in comparison to Williamson fluid. In contrast to the cone, the wedge has a greater impact of Fr on velocity, temperature, and concentration. Additionally, it is discovered that the enlarged values of the Williamson parameter decrease
fluid velocity while increasing temperature and concentration dispersion. By adjusting the surface suction, magnetic field strength, and permeability of the porous material, fluid velocity can also be reduced to a minimum. Fr, M, Nt, and K all increase fluid temperature,
while the suction parameter decreases fluid temperature. Non-Newtonian fluid has applications in the field of lubrication in numerous devices such as micro heat exchangers, micro cooling systems, micromixers, and so on. This study has a substantial influence on numerous engineering applications
that analyse energy transfer in thermal equipment, designing heat exchanger devices and engines of gas turbines.
