Analytical model of the dielectric material with embedded nanoparticles doped with conductive atom clusters containing the interphase space charges has been developed. A combined solution of the permittivity equation of the heterogeneous system with the Gauss-Codazzi and the electric potential continuity equations is allowed to simulate the relative permittivity of the composite dielectric material as a function of the concentration of the embedded nanoparticles, as well as the space charge content. The simulations for the Polytetrafluoroethylene (PTFE) dielectric material with embedded carbon nanoparticles doped with Fe atom clusters showed that the relative permittivity of the PTFE nanocomposite increases with increasing the amount of the embedded CNPs doped with Fe clusters and the charge content. In absence of embedded CNPs, the solution reduces to the Maxwell-Garnett equation.
The purpose of this article is to investigate the thermal radiation effects on unsteady hydro-magnetic viscous dissipative fluid flow of an incompressible and electrically-conducting past an oscillating vertical plate in a porous medium with variable surface conditions in the presence of chemical-reaction. The Ritz FEM has been applied to solve the governing equations of the flow. The numerical solutions for the fluid velocity, fluid temperature, and fluid concentration were presented graphically. Numerical results of the skin-friction are presented in tables. It has been found that the fluid temperature decreased in the boundary-layer as the radiation parameter increased whereas it is increased when Eckert number increased. Increase in the Schmidt number and chemical reaction tends to decrease the concentration of fluid. The permeability parameter, Eckert number, and the time tends to accelerate the fluid velocity whereas magnetic field, radiation and chemical reaction tends to decelerate the fluid velocity in case of cooled plate and opposite effect is observed in case of heated plate. These results are in very good agreement with earlier reported studies.
In a steel plant, the health, safety and security of staff, machinery and the environment are of severe concern as steel plant is a hazardous industry. Employee's health and security is essential as it impacts both financial and social factors. Steel plant management needs to recognize the benefits of secure job settings and gradually implement safety management methods to prevent dangerous occurrences, avoid losses of manufacturing and resources, and fall-outs connected with accidents. Due to the nature of the job, most health risks were encountered by employees in the steel industry. The governing culture of the organization examines how well safety processes and laws in an organization are being implemented. It was intended that safety procedures in India's steel-making business be investigated and described. The safety situation at work was conducted as a moderated interview with steel industry expert’s through semi-structured questionnaires. The analysis resulted in a detailed description of safety practices to be followed for accident prevention and increased productivity at work.
The aim of this paper is to reduce complexity in the overall design of Go- Kart to make it simple and light in weight without any premature failure and downfall in performance, since the efficiency of vehicles mainly depend upon the optimum design of its various elements. The Finite Element Analysis (FEM) method was used to create, evaluate, and recast the optimal Go-kart design to attain its objective. In addition to CAD software (SolidWorks and CATIA) were also used to design and analyse Go-Kart elements (chassis design, frame, composites, steering mechanism, braking system, and drive train design). So, finally an optimum proposal design would be prepared by considering its serviceability, safety, strength, cost, standardization, ergonomics, and aesthetics.
The removal of lead (II) from wastewater using Borasus flabellifer coir powder as adsorbent has been investigated in this paper. The experiment was carried out in batch mode to find out the effect of several process parameters like agitation time (0-120 min), adsorbent dosage (0.05 to 6.0 g in 50 mL solution), and concentration of lead ion (20-100 mg/L); temperature (273-323 K), and pH (3-10). The wastewater samples are analyzed quantitatively using Atomic Absorption Spectrometer (AAS). The equilibrium agitation time was achieved at 40 minutes. The maximum percentage removal of lead (II) was achieved at pH=8. The adsorption kinetic studies follow second order. Both Langmuir and Freundlich models for lead adsorption onto adsorbent are proved to be the best fit observed from high regression coefficient R2 value. The maximum metal uptake is 34.482 mg/g. The thermodynamic parameters such as change in Gibb's free energy (ΔG), Enthalpy (Δh) and Entropy (Δs) reveal the feasibility, irreversibility, spontaneity, and endothermic nature. Scanning Electron Micrographs of the adsorbent indicates the surface morphology and its porous nature. The results obtained in this study illustrate that the adsorbent is expected to be an effective and economically viable adsorbent for lead removal from wastewater.
A comprehensive study of recent findings suggest ways to counter fire and its spread using passive fire protective methods. The current scenario reported in perspective of Indian standpoint published by Fire Security Association of India (FSAI), wherein on an average 20,000 people die every year due to fire driven incidents and as per U.S. Fire Administration (USFA), which states that the total number of reported fire incidents in 2017 alone within U.S. has been 1 million, out of which the confirmed number of deaths were over 3,000 and the damage to property was over $23.0 billion. With continued interest of the Indian government in infrastructure development, key rules such as NBC are being used to implement safe from fire premises; but on due diligence, a gap analysis revealed that there is lack of education among the general masses about the evacuation and extinguishing capacity of a building. This paper is an analysis of several research works on building fire that illustrates the information needed to identify the cause of fire related design attributes. In retrospect, this review gives an overview and brief study for the authors and organizations to access utmost of the information regarding fire safety in buildings, respectively.
