The current investigation deliberates the consequence of glycerin‐based carbon nanotubes with velocity slip in Darcy‐Forchheimer porous medium on a convectively heated Riga plate. Fourier heat flux theory was replaced by Cattaneo‐Christov theory. Moreover, nonlinear facets radiation are also included energy expression, and this creates expression which becomes highly nonlinear. governing flow problems altered into an ODE model help suitable variables. reduced models solved numerically...
This research communication explains the flow of water/kerosene‐based CNTs (carbon nanotubes) over a Riga sheet. The energy analysis is debated with availability radiation, viscous dissipation, and convective heating conditions. Two divisions CNTs, like, SWCNTs (single‐wall carbon MWCNTs (multiwall nanotubes), are considered. pertinent variables applied to overhaul governing mathematical models into ODE expressions. expressions analytically solved by HAM (homotopy method) numerically MATLAB...
An investigation of the thermal performance water‐conveying nanospheres (magnetite (Fe 3 O 4 ) and silver (Ag)) subject to variable controls, namely, surface temperature normal heat flux, has been made. A bidirectionally elongating is used generate an unsteady flow mechanism with action Lorentz force. Derived equations basic laws are firstly nondimensionalized then numerically solved by applying Keller‐Box method. The local Nusselt number for both cases calculated discussed. Percent‐wise...
The present paper has enormous applications including fields of crystal growth, material processing, spacecraft, underground spread chemical contaminants, petroleum reservoirs, waste dispersal and fertilizer migration in saturated soil, alloy solidification, many more. importance double-diffusive convection been recognized various engineering applications, it thoroughly investigated theoretically. In the presence a constant heat source/sink on both layers, double...
The current analysis provides the important insights of Sisko nanofluid flow over a wedge with thermal radiation and viscous dissipation effects. Buongiorno model, which includes Brownian movement thermophoresis, is taken into consideration. Momentum, temperature, nanoparticle concentration equations are used to simulate problem. suitable similarity variables applied governing partial differential (PDEs) yield dimensionless ordinary (ODEs). MATLAB function bvp4c has been resolve resulting...
This study on communicative competence of secondary school students Bhutan was conducted with the lower, middle and higher under four districts Chukha, Samtse, Paro Thimphu. The aimed to explore why proficiency generally perceived low as reported by LaPrarie (2014). Random sampling survey questionnaire administered 864 purposive interviews 24 teacher 2 curriculum developers from Royal Education Council. Other data collection methods included classroom lesson observation documentary analysis....
This study introduces the C exp average assignments and investigates its properties using various ladder graphs. The graphs can be found in every communication networks. Ladder networks are increasingly being used everyday life for monitoring environmental applications such as domestic, military, surveillance, industrial, medical applications, traffic management. These datasets afflicted by representation of graph structure. It aids visualisation comprehension data analysis. labeling is...
Classical mean labeling of a graph G with p vertices and q edges is an injective function from the vertex set to {1,2,3, …, + 1} such that edge labels obtained flooring average arithmetic, geometric, harmonic, root square each edge’s end distinct, }. One operations duplicate graph. The classical meanness graphs formed by duplicating numerous standard discussed in this study.
In this work, we study the effect of nonlinear source term in Black-Scholes model by finding solution it. We use mathematical concepts existence and uniqueness to arrive conclusion. The transformation equation into heat leads through fixed-point theorems, semigroup theory, certain regularity conditions imposed on variables.
Aims: This study aims to examine the effect of qualification and experience level on students’ academic achievement in mathematic five colleges under Royal University Bhutan. 
 Study Design: It is a quantitative where researcher tests significance difference mean students concerning teachers’ qualifications level.
 Place Duration Study: Five Bhutan spread across districts were considered for between July 2020 2021.
 Methodology: A sample 25 university mathematics teachers (21...
Boys outperformed girls in mathematics test scores as per the recently conducted PISA-D Bhutan. Further, of 2017 from a total 28,070 STEM-related jobs, 34.3% are female and 64.7% male. Since educators’ teaching practices associated with their beliefs, this study aims to investigate some specific beliefs held by educators on gender difference performance students. It employed an explanatory sequential mix-method design. Three districts Bhutan namely Tashigang, Samdrup Jongkhar, Samtse were...
This research explains the results of a study that investigated impact mentorship in fostering leadership growth at selected primary school. The has adopted mixed methods explanatory sequential design. quantitative data was administered through survey questionnaires to 80 respondents. qualitative collected using semi-structured interview with participants (seven principals and three vice principals). Survey were thirteen-item questions demographic information few open-ended collect data....
Huanglongbing (Citrus Greening) is the most devastating citrus disease caused by phloem-inhabiting bacteria carried insect vector, Asian psyllid (Diaphorina citri). In Bhutan, production and movement of seedlings new orchard establishment have been restricted after Citrus Greening was detected in orchards. To address this problem, Agriculture Research Development Centre-Wengkhar has initiated research on clean propagation through shoot tip grafting. This study assessed efficiency grafting...
This paper is a case study of Samtse Higher Secondary School to the impact covid-19 pandemic in school during year 2020 academic session.The will assess and evaluate how performed both non-academic by its student it was affected particularly learning performance.The situational analysis remote amidst pandemic.The purpose see relationship with normal situation terms efficacy quality student.Furthermore, also an attempt understand school's strength, weakness, threat opportunities vis-à-vis...
