This paper is a simple summary of the first most basic definitions in Algebraic Geometry as they are presented in Dummit and Foote ([1]), with a focus on establishing a dictionary between algebra and geometry. In particular this dictionary helps in visualizing certain computations that take place in polynomial rings. Among these are decomposing ideals in a manner analogous to prime factorizatio...

This article will attempt to provide a fast track introduction for those that need to learn the UML basics and to begin to start understanding UML so that it can be incorporated into your development project. I shall begin by clarifying exactly what UML is and is not. Then question why we should use the UML at all. Then I will conclude part 1 of this article with a high-level tour of the UML mo...

Efforts to find an ideal model for pancreatitis date back to 1960’s. Many models are suggested since then. Every model has its own advantages and disadvantages. Some of these models test etiology while others simulate the complications of pancreatitis. An ideal model which by itself demonstrates all aspects of pancreatitis including systemic changes is yet to be described. In this review we tri...

This article is a pedagogical introduction to density-functional tight-binding (DFTB) method. We derive it from the density-functional theory, give the details behind the tight-binding formalism, and give practical recipes for parametrization: how to calculate pseudo-atomic orbitals and matrix elements, and especially how to systematically fit the short-range repulsions. Our scope is neither to...

Arduino is a popular open source hardware toolkit for science and engineering education due to its easy use and various good examples. But, students or beginners who have no experience and knowledge of electronic engineering or programming languages still feel a considerable barrier to use Arduino. This study analyzes the barrier of beginners in using the open source hardware. In order to resol...

Although experts should be well positioned to convey their superior knowledge and skill to novices, the organization of that knowledge, and particularly its level of abstraction, may make it difficult for them to do so. Using an electronic circuit-wiring task, the authors found that experts as compared with beginners used more abstract and advanced statements and fewer concrete statements when ...
