This paper provides systematic presentation of the issues related to methodology, and offers some possible solutions for analysis of different aspects of child development, especially preschool age. These issues are related to the definition, acceptance and preparation of the existing theories on development, which include analysis of the whole child's self his/her surroundings, and his/her act...

A finite probability mixture model is combined with a contingent valuation model to analyze the existence of differential market segments in a hypothetical market. The approach has at least two principle benefits. First, the model is capable of identifying market segments within the hypothetical market. Second, the model can be used to estimate WTP/WTA within each segment. The model is illustra...

This study aims to extract Glycyrrhizic Acid (GA) from Glycyrrhiza glabra L. (licorice) using a novel, high efficiency, and low-cost extraction method. Water was chosen as the proper solvent for the extraction process to eliminate the requirement of harmful and toxic solvents, prepare an environmentally friendly process, and reduce the costs. The effect of differe...

A review is given of the status of hypotheses about various undiscovered particles. Magnetic monopoles, intermediate bosons, heavy leptons, scalar particles, quarks, tachyons and gravitons are discussed, along with speculations about the newly discovered neutral mesons. This review was completed in December 1974. Rep. Prog. Phys. 1975 38 731-770

The purpose of the study was to investigate the effects of inquiry-based computer simulation with heterogeneous-ability cooperative learning (HACL) and inquiry-based computer simulation with friendship cooperative learning (FCL) on (a) scientific reasoning (SR) and (b) conceptual understanding (CU) among Form Four students in Malaysian Smart Schools. The study further investigated the effects o...

This report accompanies current research on membrane-inspired graph transformation systems. Contained within are details of a hypothetical model of cellular viral infection and subsequent immunological response for some imagined multicellular organism. Section 2 presents the graph transformation rules in a concrete model (after the addition of aggregating attributes) detailing the complete beha...
