Brownian Motion and Thermophoresis Effects on Casson Nanofluid Over a Chemically Reacting Stretching Sheet with Inclined Magnetic Field

The contemporary study explores the impact of thermophoresis and Brownian motion on two-dimensional magnetohydrodynamic boundary layer flow of Casson nanofluid over a chemically reacting stretching sheet. To control the heat and mass transport phenomena we also included the thermophoresis diffusion coefficient, Brownian motion parameter, and thermal radiation. The regular physical governing systems of partial differential equations are transmogrifying into ordinary differential equations. The transmogrifying governing equations are checked numerically by using Runge-Kutta-Fehlberg method. The numerical solutions for heterogeneous governing parameters such as Schmidt number, Joule heating parameter, and permeability parameter, chemical reaction parameters on velocity, temperature, and concentration profiles were presented. Numerical and Graphical results have described the parameters of concentration entering into the modeled problems. The analyzed numerical values of skin friction coefficient, Nusselt and Sherwood numbers also determined and chat about in the formal property of several assorted parameters

A Survey on Emulation Testbeds for Mobile Ad-hoc Networks

AbstractMobile Ad hoc Network (MANET) can be said as a collection of mobile nodes, which builds a dynamic topology and a A resource constrained network. In this paper, we present a survey of various testbeds for Mobile Ad hoc Networks. Emulator provides environment without modifications to the software and validates software solutions for ad hoc network. A field test will show rather the simulation work is going on right track or not and going from the simulator to the real thing directly to analyze the performance and compare the results of routing protocols and mobility models. Analyzing and choosing an appropriate emulator according to the given environment is a time-consuming process. We contribute a survey of emulation testbeds for the choice of appropriate research tools in the mobile ad hoc networks

Heat transfer of a nanofluid over a stretching sheet with velocity slip and temperature jump in porous medium in the presence of chemical reaction and radiation

In this study, heat transfer of a nanofluid over a stretching sheet with velocity slip and temperature jump in porous medium in the presence of chemical reaction and radiation is theoretically investigated. The governing partial differential equations with the corresponding boundary conditions are reduced to a set of ordinary differential equations via Lie group analysis. Numerical solutions of these equations are obtained by Runge-Kutta fourth order method along with shooting technique and the results obtained for different governing flow parameters are drawn graphically and their effects on velocity, temperature and concentration profiles are discussed. The reduced Nusselt number and reduced Sherwood number are presented in tabular form. It is noted that the reduced Nusselt number increases with the increase of Prandtl number but the reduced Sherwood number decreases. The effect of temperature jump parameter decreases the reduced Nusselt number and reduced Sherwood number

A nod in the wrong direction : Does nonverbal feedback affect eyewitness confidence in interviews?

Eyewitnesses can be influenced by an interviewer's behaviour and report information with inflated confidence as a result. Previous research has shown that positive feedback administered verbally can affect the confidence attributed to testimony, but the effect of non-verbal influence in interviews has been given little attention. This study investigated whether positive or negative non-verbal feedback could affect the confidence witnesses attribute to their responses. Participants witnessed staged CCTV footage of a crime scene and answered 20 questions in a structured interview, during which they were given either positive feedback (a head nod), negative feedback (a head shake) or no feedback. Those presented with positive non-verbal feedback reported inflated confidence compared with those presented with negative non-verbal feedback regardless of accuracy, and this effect was most apparent when participants reported awareness of the feedback. These results provide further insight into the effects of interviewer behaviour in investigative interviewsPeer reviewedFinal Accepted Versio

Modular A4A_4 symmetry in 3+1 active-sterile neutrino masses and mixings

Motivated by the significance of modular symmetry in describing neutrino masses and flavour structure, we apply the $A_4$ modular symmetry in 3+1 scheme of active-sterile neutrino mixings. Neutrino oscillation observables in 3$\sigma$ range are successfully reproduced through the vev of the modulus $\tau$ in normal hierarchy(NH) as well as inverted hierarchy(IH). We have also studied other phenomenologies regarding effective neutrino masses $m_{\beta}$ in tritium beta decay and $m_{\beta\beta}$ in neutrinoless double beta decay. Mixings between active and sterile neutrinos are analysed in detail and the mixing elements $\vert V_{i4}\vert$ are found to satisfy the experimental bounds. The best-fit values of the neutrino mixing angles and mass squared differences ratio are determined using minimum $\chi^2$ analysis. This model predicts best-fit values of the neutrino oscillation observables as $\sin^2\theta_{23}=0.572$, $\sin^2\theta_{12}=0.313$, $\sin^2\theta_{13}=0.022$ and $r = \sqrt{\Delta m_{21}^2/\Delta m_{31}^2}= 0.172$ for NH whereas $\sin^2\theta_{23}=0.602,$ $\sin^2\theta_{12}=0.288,$ $\sin^2\theta_{13}=0.022$ and $r = \sqrt{\Delta m_{21}^2/\vert\Delta m_{32}^2\vert}= 0.172$ for IH. Our analysis is also consistent with the latest Planck cosmological upper bound on the sum of neutrino masses $\sum m_i <0.12$ eV.Comment: 19 pages, 11 figure

Diabetic eye screening in multi ethnic population of Malaysia: epidemiological risk factors for development of diabetic retinopathy

Background:The objective of this study is to evaluate epidemiological risk factors for development of diabetic retinopathy.Methods:The cases of type-2 diabetes mellitus attending Melaka Manipal medical college, Malaysia were retrospectively reviewed. The epidemiological characteristics of diabetic retinopathy were estimated. The cases were graded according to degree of retinopathy in to: non-diabetic retinopathy group and diabetic retinopathy. Clinical and biochemical studies were used for studying the risk factors associated with development of retinopathy.Results:The prevalence of diabetic retinopathy in the population was 21% in known diabetic subjects and was significantly higher in men than in women (21.3% vs. 14.6%) with increasing age and duration of diabetes. Ethnicity is a complex, independent risk factor for diabetic retinopathy. Sight threatening diabetic retinopathy, and clinically significant macular edema was higher in people of Malaysia (20%) when compared with Chinese (16%) and Indonesians (12%). In all, 55 percent of patients with known diabetes mellitus had never undergone an eye examination. Among patients who had undergone eye examinations, 32.8 percent had the last examination within the last one year, 49.8 percent within the last one to two years, and 17.4 percent more than two years ago.Conclusion:Diabetic retinopathy is highly prevalent in the patients with type-2 diabetes mellitus in Malaysia. Besides blood glucose, many factors are associated with the present and development of diabetic retinopathy.
