A Hierarchical Structure for an Organic Chemistry Course

A Statistical Evaluation: Peer-led Team Learning in an Organic Chemistry Course

Peer-led team learning, PLTL, also known as Workshop Chemistry, is one of five systemic reform initiatives in chemistry funded by the National Science Foundation in the 1990s (1, 2). Since then PLTL workshops in general chemistry, organic chemistry, and biochemistry have been implemented in more than thirty post-secondary institutions and in one Montana high school (2, 3). The PLTL model has al...

Microwave Assisted Synthesis of Biodiesel in an Undergraduate Organic Chemistry Laboratory Course

Engineering students in a one-semester organic chemistry laboratory course prepared biodiesel by using either microwave or conventional heating in a discovery-based experiment. The laboratory design was to show improvement in student awareness about the use of microwave heating in organic synthesis in general, and specifically in the preparation of biodiesel. The students were polled before and...

An Efficient Statistical Approach for Automatic Organic Chemistry Summarization

In this paper, we propose an efficient strategy for summarizing scientific documents in Organic Chemistry that concentrates on numerical treatments. We present its implementation named yachs (Yet Another Chemistry Summarizer) that combines a specific document preprocessing with a sentence scoring method relying on the statistical properties of documents. We show that yachs achieves the best res...

A Three-Level Mathematical Model for an r-interdiction Hierarchical Facilities Location Problem

In general, any system may be at risk in a case of losing the critical facilities by natural disasters or terrorist attacks. This paper focuses on identifying the critical facilities and planning to reduce the effect of this event. A three-level model is suggested in the form of a defender-attacker-defender. It is assumed that the facilities are hierarchical and capable of nesting. Also, the at...
