Abstract:
This paper contains possibilistic method based on a linear and exponential membership function and its application to define the critical path in project network. It contains four criteria - cost, duration, quality and risk of the project activities which are to be considered as critical in project organisation. A model is formulated for selection of critical path in trapezoidal fuzzy environment. For find the solution of this multi-criteria project management problem fuzzy programming technique with linear and exponential membership is utilized with alpha level set concept. We have provided numerical illustration to validate working of the proposed approach. To analyze the performance of the proposed approach, we have compared it with closely related fuzzy group multi-criteria decision making method for the critical path selection. Degree of satisfaction is calculated for different values of  levels to validate the applicability of this new approach.

Abstract:
In this paper, we study the low Reynolds number steady flow in Sinusoidal tube of varying cross section with permeable wall. The fluid is assumed to be incompressible and Newtonian. The wall assumed to be rigid and permeable. The wall permeability is assumed to be a function of axial distance and obeys Starling’s Law. We are interested to analyze the effects of Reynolds number and permeability on flow characteristics when the initial flux in the tube is prescribed. The effect of variable permeability of the wall on various parameters on flow characteristics is discussed.

Abstract:
Solvent extraction of Iron (III) from aqueous ortho phosphoric and perchloric acid solutions by Tri-benzyl amine (TBA) in chloroform has been studied. Effect of several variables like concentration of the extractant, metal ion, acidity, foreign ions etc. were studied on the extraction. The extractions are nearly quantitative from both the acid solutions employed in the study. Based on the results obtained, the probable extracted species are also suggested. The results were compared with the estimation of iron using other reagents. Attempts were made to apply the method successfully for the estimation of iron in alloys and industrial effluents.

Abstract:
Manufacturing is the application of tools and a processing medium to transform the raw materials into physical article for consumption. This effort includes all intermediate processes required for the production and integration of the products mechanism. Manufacturing systems consist of extensive interactions between people, information, materials and machines. Typically one of the main problem is to deal with the diversity of the products. A complicated feature arising in manufacturing systems is that of synchronized resource possession. The manufacturing of a part requires a machine and an operator simultaneously. There is a considerable need to develop a methodology based on queueing theory to handle the delay and blocking issues of manufacturing systems. A successful implementation depends on the ability to eliminate all forms of waste, continuous improvement; employee involvement, disciplined implementation, supplier participation, reorganization of production floor, modular designs, cell layout, process control and total quality creation,

Abstract:
The traditional theory of reliability is based on the Bernoulli trials, i.e., either success or failure. However, itseems unrealistic for enormous complex systems like computer networks. To overcome this issue, in the present study, an effort has been made regarding the development of a mathematical model for a computer network system and analysis of fuzzy availability of the same. The concepts of constant failure, constant repair and coverage factor have been used for the development of the model. The impact of coverage factor, repair rates and failure rates of components has been analyzed on the fuzzy availability of the system. Markov birth-death process has been used for the development of Chapman-Kolmogorov differential equations. Theleading differential equations have been simplified by Runge–Kutta method of order four using MATLAB (Ode 45 function).

Abstract:
Polyaniline-iron oxide nanocomposites were successfully synthesized by in-situ polymerization method. The polyaniline metal oxide nanocomposites formed were characterized using StellarNet UV – VIS – NIR spectrometer (Blue – Wave Miniature; Model: UVNb). The optical properties investigated include; absorbance, transmittance, reflectance, refractive index, extinction coefficient and energy band gap. Our results show that the absorbance of polyaniline – iron oxide nanocomposites decreases as amount of iron oxide nanoparticles increased with a peak value of approximately 1.00. Transmittance of polyaniline– iron oxide (PANI/Fe2O3) nanocomposites decreases as amount of iron oxide nanoparticles increased with a peak value of 58% at 800nm. Reflectance within the regions of the electromagnetic spectrum considered was found to be very low. A peak refractive index value of 2.64 was obtained at 700nm for the synthesized iron oxide nanoparticles. The extinction coefficient of our synthesized nanocomposites decreased with increase in the concentration of iron oxide nanoparticles. Optical band gap of polyaniline iron oxide nanocomposites ranged from 2.50 eV to 2.20 eV.Our x – ray diffraction result show that the PANI/Fe2O3 nanocomposites formed have Orthorhombic crystal structure with preferred orientation in the (111) plane.

Abstract:
Phytochemicals are secondary metabolites produced by medicinal plants. Some haveshown significant antimicrobial activity to disease causing bacteria’s that have developed resistance strains to synthesized drugs. Therefore this investigation is aimed atinvestigating the antimicrobial property and to confirm the growth inhibitory activity of anthocyaninfrom Phyllanthus muellerianus plant leaves extract against human pathogen such asEscherichia coli, Staphylococcus aureus, and Salmonella typhi. Spectroscopic (UV/Vis, FT-IR and 1H NMR) techniques were employed in characterization, while disc diffusion method was used for antimicrobial property and to confirm the growth inhibitory activities.UV-Vis absorption spectrum shows peaks at 313 nm and 482 nm being attributes of anthocyanin. According to FT-IR and 1H NMR investigations the tested sample have cyanidin glycoside and peonidin glycoside. Phyllanthus muellerianus plant leaves extractdemonstrated promising activity against the test organisms. The extract exhibits activity on all the test organisms producing zones of inhibition ranging from 11-18mm. The activity was more pronounced (MIC 4.0 mg/mL) against S. typhi while the least activity was against E. coli (MIC 50mg/mL). However, the S. typhi and E. coli were inhibited in all concentration of extract assayed respectively. The minimum inhibition concentration (MIC) showed that the extract had lowest MIC value (4.0 mg/mL) against S. typhi.This investigation therefore supports the traditional medicinal use of P. muellerianus leaves as a source of antimicrobial agents.

Abstract:
Different solvents can affect the equilibrium constant of a reaction by differential stabilization of the reactant or product. The equilibrium is shifted in the direction of the substance that is preferentially stabilized. Stabilization of the reactant or product can occur through any of the different non-covalent interactions with the solvent such as H-bonding, dipole-dipole interactions, van derwaals interactions etc. Although the Solvent Effect on the Rate and Mechanism of the various type of reaction has been reported but very little attention has paid towards the study of the Solvent Effect on the Thermodynamic Activation Parameter and the solvant-solute interaction, particularly for an ion-dipolar reaction. In order to highlight the above noted idea, it has been proposed to make the kinetic study of the solvent effect on the alkali catalysed hydrolysis of Ethyl Acetate has not been paid even a little attention so far.

Abstract:
Finsler geometry is a kind of differential geometry, which was begun by P. Finsler in 1918. It is regularly tried to be as a speculation of the Riemannian geometry. The particular explanation of progress of Finsler geometry can be confined into four periods. The gigantic season of the legitimate premise of progress of Finsler geometry began in 1924, when the three geometricians J. H. Taylor, J. L. Synge and L. Berwald meanwhile started the work in this field. Berwald is the squeezing man who has introduced the opportunity of relationship in the hypothesis of Finsler spaces. He is the producer of Finsler geometry and, as required, the facilitator. He has cultivated a speculation with unequivocal reference to the hypothesis of cadenced improvement in which the Ricci lemma doesn't hold perfect. J. H. Taylor gave the name 'Finsler space ' to the complex outfitted with this summarized assessment. The subsequent time period began in 1934, when E. Cartan dissipated his theory on Finsler geometry. He showed that it was to be certain possible to depict connection coefficients and as such covariant accomplices with a persuading objective that the Ricci lemma is satisfied.
