Abstract:
Introduction:
The quality of life of the worker has become an interest of matter to the professionals engaged in the science of
work, however, there's a lack of evaluative methods so far. Thus, the construction of a strong tool to analyse the
workers in preventive and corrective actions that involve internal and external environment of which the worker
is inserted, becomes extremely important to the academic community.
Objective:
Create focus groups to operationalize the construction and validation of the questions referring to the quality of
life of the workers.

- Effect of Baffle on Mixed Convection Flow in a Vertical Channel
Filled With Electrically Conducting Fluid

Abstract:
The magnetohydrodynamic flow in a vertical double passage channel using Robin boundary conditions in the
presence of applied electric and magnetic field has been investigated. The fluid is electrically conducting while
the channel plates are electrically insulated. The general equations that describe the discussed problem are
coupled nonlinear ordinary differential equations and hence closed-form solutions cannot be found. However
approximate analytical solutions are found using regular perturbation method valid for small values of
Brinkman number and using differential transform method valid for all values of Brinkman number. The
channel is divided into two passages by means of a solid, thin, perfectly conducting baffle and hence the
velocity will be individual in each stream. The governing equations which are coupled nonlinear ordinary
differential equations are solved analytically using.....

Abstract:
The paper examines separation of the methods of separation of variables of nonlinear partial equations. These
equations have dependent and independent nonlinear variables. They are used in the analysis of physical and
chemical processes that are complex with many variables, and these variables are obtained by derivatives. Two
cases of the separation process were detailed for heat conduction using homogeneous and nonhomogeneous
cases. Several other applications where the separation process is applied were discussed, and a general method
for separation was presented. It is clear that this process of separation is used in a number of physical and
chemical applications.

Abstract:
This research focused to find out chemical and structural suitability of novel Hydroxyapatite composite synthesized using Chloroapatite and 2-hydroxyethyl methacrylate as Dental filling material. For that, Solid State Sintering technique was used to produce Hydroxyapatite using Sri Lankan Chloroapatite and Calcium hydroxide. After reinforcing it with 2-hydroxyethyl methacrylate, physical and chemical properties were examined via comparing and contrasting it with the human tooth and commercially available Glass Ionomer cement (GIC), used in the field of Dentistry. Results show there is a close similarity between the synthesized product and the human tooth. Therefore, the study concluded that synthesized Hydroxyapatite composite can be used directly as a substitution for commercial dental filling material.

Abstract:
This paper reviews the problem related to e-waste, improper disposal techniques and related environmental
issues. Life span of electronic devices are getting short day by day due to technological advancement ultimately
increase the volume of e-waste. It also increases the health hazards and environmental pollution in many ways
such as soil, water and air pollution. So recovery of metals using different technology gives alternative of
disposal. Various physical and chemical methods, metallurgy and biological methods have been used since
years to reduce the pollution related to e-waste. To use recovered copper for synthesis of copper nanoparticles
can be prove economical option. Copper nanoparticles can be synthesized using physical and chemical methods.
Cu NP is used as catalyst, disinfectant and in electronic sector. It has high conductivity and high surface to
volume ratio. So, different method for recovery of copper and synthesis of copper nanoparticles from recovered
copper using method has been reviewed with application of copper nanoparticles.

- Differential Transform Method for the Heat Equation

Abstract:
Differential transform method (DTM) is the multi-step form of numerical method to solve differential equations.
The method was first introduced by Zhou (1986) and is used for giving an exact value for nth derivative to solve
analytical functions having known or unknown boundary conditions. This method offers analytical solution in
polynomial terms. The method is rather different than the traditional form of Taylor series method offering
computations with required derivatives in data function (Tabatabaei et al., 2011). The problems and approximate
solutions are elaborated here to give a better insight of the DTM. The method is clearly useful in solving linear
as well as non-linear value problems for the analysis of electric circuits. Thus, it possesses the potential to
reduce the size of computational work..
