ANALYZE OF MATERIALS DUE TO THEIR FLOW BEHAVIORS

ABSTRACT
In this article, four different samples’ flow behaviors are analyzed; either they are Newtonian or Non-Newtonian materials. Parallel plate rheometer is preferred to adjust the shear stress and shear rate relationship of the specimens at 25°C and 70°C and test results are evaluated with the plotted flow and viscosity curves. Then, samples are categorized due to their time dependence or shear stress dependence.

1. INTRODUCTION
A Newtonian fluid is a fluid whose stress versus rate of strain curve is linear and passes through the origin. The constant of proportionality is known as the viscosity.
A simple equation to describe Newtonian fluid behavior is (1)
Where;
τ is the shear stress exerted by the fluid [Pa] μ is the fluid viscosity - a constant of proportionality [Pa·s] is the velocity gradient perpendicular to the direction of shear [s−1]
For a Newtonian fluid, the viscosity depends only on temperature and pressure (and also the chemical composition of the fluid if the fluid is not a pure substance), not on the forces acting upon it. Water is a typical Newtonian fluid.
In a Non-Newtonian fluid, the relation between the shear stress and the strain rate is nonlinear. Therefore a constant coefficient of viscosity cannot be defined and they can even be shear –stress dependent or time-dependent.
Shear stress dependent materials are divided into two groups. In shear thickening materials, the viscosity increases with increased shear rate. These materials are categorized as dilatant materials such as sand in water. In shear thinning materials, the viscosity decreases with increased shear rate. These materials are called pseudo plastic materials such as latex, paint, syrup...
Time dependent materials are also divided into two groups. Apparent viscosity increases with duration...

Factors Affecting the Buying Behaviour of the Consumers: Branded vs. Imitation Clothes

...Factors Affecting the Buying Behaviour of the Consumers: Branded vs. Imitation Clothes Mary Jonique M. Enoria Gracil L. Gomez BSBA-MKTG3A \ Abstract The relationship between consumers’ decision-making styles and their choice between imitation and branded clothing is investigated using a sample of Filipino consumers. The objective of this paper is to gauge the factors affecting purchase decision taking comparative perspective as base. Findings are calculated using survey technique and weighted mean method with a sample of 30 participants in Valenzuela. The objective of this paper is to analyze the significance of demographic profile of consumers affecting the purchase decision of branded garments and to observe from comparative perspective of their awareness about different apparel brands available in the Philippines market and also to find out whether there is a significant difference in total expenditure on branded apparels done by male and female. In developing countries, consumers are becoming conscious of fashion brands. The research was directed towards understanding the determinants of clothing involvement of Filipino perspective. A primary research study was conducted on Valenzuela Residents aged between 13 and 22 years using the survey method to know the factors affecting the buying behaviour of fashion clothing in their lives. The scale constructs related to consumption involvement, product involvement, advertising involvement and purchase decision......

Emotions, personal problems, hunger, are some of the examples of internal forces that may cause distractions. While noise extracurricular activities and work are examples of external forces that may also cause distractions to the part of the student. Unlike the internal forces, external forces are the pressures that arise from outside the concern of the student and yet also affect the student behaviour.
