The study on the influences of superabrasive grain spatial

Recently, a virtual single-layer cubic boron nitride (CBN) grinding wheel model is developed by simulating each wheel fabrication step, which makes the estimation of the single grain material removal mode possible in grinding. Therefore, the study of the grain–workpiece interaction through microcutting behavior on the abrasive grains becomes necessary for the quantitative investigation of

QUALITATIVE RESEARCH IN ORGANIZATIONAL

Qualitative and quantitative approaches to the study of organizations are not mutually exclusive. Yet, over the last several years they have tended to become as such. Also, the interest in qualitative research of organizations seems to be renewing in the recent years.

Cannabinoid receptors. Before the 1980s, it was often speculated that cannabinoids produced their physiological and behavioral effects via nonspecific interaction with cell membranes, instead of interacting with specific membrane-bound receptors.The discovery of the first cannabinoid receptors in the 1980s helped to resolve this debate. These receptors are common in animals, and have been

Quantitative analysis of behavior

Quantitative analysis of behavior is the application of mathematical models, conceptualized from a robust corpus of environment-behavior-consequence interactions in the experimental analysis of behavior, with the aim to describe and/or predict relations between a dependent variable and all possible levels of an independent variable.

Qualitative Methods Attitudes And Behavior, Research

Qualitative methods differ from quantitative methods largely because their ultimate purpose is different. The goal of qualitative research is to arrive at some general, overall appreciation of a phenomenon—highlighting interesting aspects and perhaps generating specific hypotheses. In contrast, quantitative research is typically designed to test relatively specific predictions. Qualitative

The radial wear of the wheel was characterized by an early transient state followed by a steady state wear regime and finally a steel rise in wear rate. The initial transient region progressed up to radial wear of 21 μm. During the steady state region, the radial wear was in the range of 21 μm to 25.5 μm.
