Abstract:
The hydromagnetic free convective flow of a visco-elastic electrically conducting fluid past a vertical porous plate through a porous medium with constant suction and heat source in presence of transverse magnetic field has been studied. The induced magnetic field and Joulean heat dissipation are neglected in this problem. Also, Boussinesq approximation has been used to find the governing equations of the flow field in presence of energy dissipation. The governing equations are solved by using multi parameter-perturbation technique. The analytical expressions for the velocity, temperature fields shearing stress, the rate of heat transfer at the plates in terms of Nusselt number have been obtained. The effects of visco-elastic parameter, on the velocity, Nusselt number, and shearing stress have been illustrated graphically, in combination with other flow parameters involved in the solution. The problem has some relevance in the geophysical and astrophysical studies

Abstract:
This paper reports on the development of 3’C-CAPP for an interactive-generative computer-aided process planning system for 2.5D part machining. However, the input details are obtained from a 3’CAM technique. Sequencing has been implemented based on operations. The operations like drilling and circular interpolation and corner milling can be identified automatically as for the order of operational preference given to a feature. Further, a scheduling based on a drill; mill (End) and mill (corner) have been developed for optimizing the time. However, a single sequencing and scheduling is perhaps not sufficient for all operations in all situations. So, there must be a change manufacturing environment with the multiple objectives number of operations, time consideration for each operation for optimization in tool and parameters change. Most of the works were carried out in determining the operation sequence on a single milling machine that can be extended to multi machines. The selection of efficient machining parameters is of great concern in manufacturing industries. The program has been developed by .Net software at backend and Visual Studio IDE at the front end.

Abstract:
In this paper we introduce the concept of near-rings in which every N-subgroup is an ideal. In [5], S. Suryanarayanan and R. Balakrishnan investigated a near-ring N in which every N-subgroup is invariant. Motivated by this concept, we probe into the properties of a near-ring N where every N-subgroup is an ideal. We discuss the properties of this newly introduced structure, and furnish a characterization and prove that all principal ideals with mate functions is a distributive lattice

Abstract:
The main purpose of this paper is to elevate the need of automotive industry in the Federal Democratic Republic of Ethiopia [FDRE]. However, the importances of automobile vehicles are being demanded, unfortunately the contribution of the automotive sector has not been focused to a great extent. Obviously, increase of auto-industry plays an important role in increase of any national economy. In addition it plays a significant role in increase employability, in trade; in transport etc. The FDRE is being done much in trade sector not in manufacture sector of automotive vehicles and spare parts that directly impinge on country’s economy. Regrettably, the automotive sector is being downgraded and has been neglected in several states of Ethiopia by various reasons. This technical paper presents the various factors effecting the growth of automotive industry Ethiopia along with plan, suggestion, improvement; damage control exercises, the agencies sense of duty includes Government Policies, human resources capacity, Public Purchase ability, Shortage of capital, Road conditions and limitations. Finally, some implications have been submitted for the smooth utility of automotive industry.

We show that weakening the hypothesis of right alternative to the three identities. 𝑤𝑥, 𝑦, 𝑧 + 𝑤, 𝑥, 𝑦, 𝑧 = 𝑤 𝑥, 𝑦, 𝑧 + 𝑤, 𝑦, 𝑧 𝑥 = 0 … 1 𝑥, 𝑥, 𝑥 = 0 … 2 And 𝑥, 𝑦 , 𝑦, 𝑦 = 0 … 3 for all 𝑤, 𝑥, 𝑦, 𝑧in the ring R will not lead to any new simple rings. In fact we show a semi prime finitely generated generalized right alternative ring is right alternative. We also show that if R is a prime finitelygenerated generalized right alternative ring of char.≠ 2,3.Then we show that nucleus is equal to the commutative center.

Abstract:
The polymer matrix composites (PMCs) are gaining popularity among automobile, aircraft and medical sector due to their promising role in manufacturing of light weight and high strength components. The wide varieties of polymers are used as matrix materials in combination with ceramics, carbon and synthetic fibers to fabricate polymer matrix composites. This paper makes an attempt to discuss the various polymeric materials used that can be used as matrix in PMCs and also focuses on their processing techniques in respect to the area of their use. The processing environment of the polymer based composites plays significant in deciding the mechanical and physical properties of the composites. The addition of certain additives like fillers, plasticizers, colorants and flame retardants during the processing can improve tensile and compressive strength, abrasion resistance and dimensional stability. Later the challenges in manufacturing of PMCs have been discussed with scope of opportunities available in the global market.

Abstract:
The concept of weakly regular rings were exclusively studied by Kovacs, Brown & McCoy, Ramamurthy, Camilo & Xiao & others, generalizes a property of regular rings. Characterization of weakly regular ring by Ramamurthy has found in theorem we find that a regular ring in right weakly regular. The theorem is a generalized properties of a right weakly regular rings. A ring which is both-left and right weakly regular is called weakly regular. For right artinian rings, right weak regularity is equivalent to regularity and biregularity.

Abstract:
The concern for the presence of a wide variety of contaminants in the environment calls for development and assemblage of information about their behavioral characteristics so that appropriate strategies can be adopted to either prevent or minimize their adverse impacts on human welfare and natural resources. This information is especially warranted for toxic chemicals that persist for extended periods of time in the environment.When chemicals enter the environment, they are usually not confined to a specific location but rather are in dynamic motion either within a medium or across the adjacent media. The propensity for a contaminant to move into and distribute itself between the media (or phases) is determined by its physical and chemical properties and environmental factors and variable.The rate of alkaline hydrolysis of ethyl cinnamate was measured over the temperature range of 40°C to 80°C in water-acetone mixture at different composition 20 to 60% (v/v). The influence of solvent variation on reaction rate was examined in term of changes in the Activation parameter. Depletion of ∆H* and ∆S* value with simultaneous increase in ∆G* of the reaction in reaction media, reveals that the reaction is Enthalpy domination and Entropy controlled. The Iso- dielectric activation energy (ED) of reaction was found to decrease from 55.43 to 45.28. The Values of Iso-kinetic Temperature which is less than 400, clearly indicates that there is no appreciable interaction between solvent and solute present in the reaction media, i.e., reaction is not ion-dipole but ion-molecule type.

Abstract:
Computation of the boundary layer parameters relies upon the game plan of equations procured from the Navier–Feeds equations for viscous fluid motion, which are introductory broadly unraveled considering the slimness of the boundary layer. The course of action suggested by L. Prandtl is essentially the essential term of power game plan improvement of the Navier–Blends equation, the course of action augmentation being performed for powers of dimensionless boundary (δ/L). The smaller boundary in this term is in zero power with the objective that the boundary layer equation is the zero supposition in an Asymptotic Turn of events (wherever Re) of the boundary layer equation (asymptotic course of action). The current paper highlights the importance of boundary layer theory

Abstract:
System of linear equations are solved either by direct methods which yield exact solution or by iterative methods which gives an approximation solution. In computational mathematics, iterative proccess plays a vital role that uses an initial guess to determine the approximation solution of any given problem. [7, 9, 10]There are several methods to solve system of linear and nonlinear equations, such as iterative methods, approximation methods, elimination methods and interpolation methods[13, 16, 17]. In this paper we use Conjugate Gradient Method to solve system of linear equations, as this is one of the most popular and well known iterative techniques for solving sparse symmetric positive definite systems of linear equations[24]. In particular, we discuss about pure conjugate gradient method and preconditioned conjugate gradient method. Numerical examples are shown for each method and comparison of these method is done based on the number of iterations and faster convergence. Thus we observe that the preconditioned conjugate gradient method is more preferred when the system is large because it gives less number of iterations and converge faster.
