Alvarez-Montan~o, Victor E.; Farías, Mario H.; Brown, Francisco; Mun~oz-Palma, Iliana C.; Cubillas, Fernando; Castillon-Barraza, Felipe F. – Journal of Chemical Education, 2017
A good understanding of ternary phase diagrams is required to advance and/or to reproduce experimental research in solid-state and materials chemistry. The aim of this paper is to describe the solutions to problems that appear when studying or determining ternary phase diagrams. A brief description of the principal features shown in phase diagrams…

Capela, Emanuel V.; Santos, João H. P. M.; Boal-Palheiros, Isabel; Carvalho, Pedro J.; Coutinho, João A. P.; Ventura, Sónia P. M.; Freire, Mara G. – Chemical Engineering Education, 2019
Through the experiments described in this article, students become acquainted with the principles behind ternary liquid-liquid systems and/or Aqueous Two-Phase Systems (ATPS), and their characterization by the determination of the binodal curve, tie-lines, tie-line lengths and critical point, as well as in applying the non-random two-liquid model…

Brazzle, Bob; Tapp, Anne – Physics Teacher, 2016
A ternary diagram is a graphical representation used for systems with three components. They are familiar to mineralogists (who typically use them to categorize varieties of solid solution minerals such as feldspar) but are not yet widely used in the physics community. Last year the lead author began using ternary diagrams in his introductory…

Oztemel, Kemal – Journal of Career Development, 2013
The goal of this study was to examine the emotional and personality-related career decision-making difficulties of high school students in Turkish culture, using the model proposed by Saka and Gati. A sample of 523 high school students filled out the Turkish version of the Emotional and Personality-Related Aspects of Career Decision-Making…

Rashkovits, Rami; Lavy, Ilana – International Journal of Information and Communication Technology Education, 2020
The present study examines the difficulties novice data modelers face when asked to provide a data model addressing a given problem. In order to map these difficulties and their causes, two short data modeling problems were given to 82 students who had completed an introductory course in database modeling. Both problems involve three entity sets…

Radford, Andrew; Kupisch, Tanja; Koppe, Regina; Azzaro, Gabriele – Bilingualism: Language and Cognition, 2007
This paper examines the syntax of "GENDER CONCORD" in mixed utterances where bilingual children switch between a modifier in one language and a noun in another. Particular attention is paid to how children deal with potential gender mismatches between modifier and noun, i.e., if one of the languages has grammatical gender but the other does not,…

MacCarthy, Patrick – Journal of Chemical Education, 1983
Reviews graphical methods for representing ternary and quaternary systems, focusing on use of triangular composition diagrams. Examines some of the relevant geometry of triangles in general, showing that right isosceles triangles possess some very advantageous features for representing ternary systems. (JN)

Hendry, David G. – Journal on Educational Resources in Computing, 2007
This article presents a project-based case study that was developed for students with diverse backgrounds and varied inclinations for engaging technical topics. The project, called History Places, requires that student teams develop a vision for a kind of digital library, propose a conceptual model, and use the model to derive a logical model and…

Philip, G. M.; Watson, D. F. – Journal of Geological Education, 1989
Uses the process of normalization in the Cartesian coordinate system which entails radial projection onto a transect to compare different compositions of minerals. Warns that the ternary diagram should not be used as a framework for calculations. (MVL)

Hu, Xiao – ProQuest LLC, 2010
The affective aspect of music (popularly known as music mood) is a newly emerging metadata type and access point to music information, but it has not been well studied in information science. There has yet to be developed a suitable set of mood categories that can reflect the reality of music listening and can be well adopted in the Music…

Campbell, Gordon – Canadian Journal of Higher Education, 1975
An examination of the issues of centralized control and parity of esteem in Canadian systems of higher education. Includes a profile of Canadian college systems in the various provinces placing them in three categories (unitary, binary, and ternary) on the basis of purpose, administrative structure, and articulation with universities.

Tasic, Aleksandar Z.; Djordjevic, Bojan D. – Journal of Chemical Education, 1983
Demonstrates construction of density constant and refractive index constant lines in triangular coordinate system on basis of systematic experimental determinations of density and refractive index for both homogeneous (single-phase) ternary liquid mixtures (of known composition) and the corresponding binary compositions. Background information,…

Kim, Dongwook – ProQuest LLC, 2009
Although a number of past studies have been aimed at characterizing iron's redox properties in aqueous systems and its contribution to natural attenuation processes of groundwater contaminants, many questions remain. It is especially important to understand the molecular properties that control the reactivity of both Fe[superscript II] and…

University of Trondheim Working Papers in Linguistics, 1993
In this volume, five working papers are presented. "Accessing Contexts with Intonation" (Thorstein Fretheim) discusses the use of intonation as a tool for understanding the context of an utterance, particularly in combination with reference. Examples are offered in Norwegian. In "'Altsa' and 'Nemlig': Two Views of Causality"…
