Anisotropic Oscillator Model
The EJS Anisotropic Oscillator model displays the dynamics of a mass connected to two opposing springs. The simulation displays the motion of the mass as well as the trajectory plot. The initial position of the mass can be changed by dragging. The unstretched lengths of the springs can changed as well via textboxes.

"Neuropharmacology, January IAP 2009"
" The neuropharmacology course will discuss the drug-induced changes in functioning of the nervous system. The specific focus of this course will be to provide a description of the cellular and molecular actions of drugs on synaptic transmission. This course will also refer to specific diseases of the nervous system and their treatment in addition to giving an overview of the techniques used for the study of neuropharmacology. This course is offered during the Independent Activities Period (IAP)
"Electromechanical Dynamics, Spring 2009"
" First published in 1968 by John Wiley and Sons, Inc., Electromechanical Dynamics discusses the interaction of electromagnetic fields with media in motion. The subject combines classical mechanics and electromagnetic theory and provides opportunities to develop physical intuition. The book uses examples that emphasize the connections between physical reality and analytical models. Types of electromechanical interactions covered include rotating machinery, plasma dynamics, the electromechanics o
"Global Enterprise for Micro-Mechanics and Molecular Medicine (GEM4), Summer 2006"
"GEM4 VisionGEM4 has brought together researchers and professionals in major institutions across the globe with distinctly different, but complementary, expertise and facilities to address significant problems at the intersections of select topics of engineering, life sciences, technology, medicine and public health.GEM4 creates new models for interactions across scientific disciplinary boundaries whereby problems spanning the range of fundamental science to clinical studies and public health ca
This book addresses the following topics: Iterations and fixed points; bifurcations; conjugacy; space and time averages; the contraction fixed point theorem; Hutchinson's theorem and fractal images; hyperbolicity; and symbolic dynamics. 151 page pdf file.
Normalization of relations with Communist China
Following on from President Carter's December 15, 1978 announcement recognizing the People's Republic of China and the establishment of diplomatic relations, Evelyn Wong looks into the divided reaction of Boston's Chinese American community to United States-China normalization. Peter H.F. Wong, President of the New England Chinese Consolidated Benevolent Association, thinks the normalization of relations is entirely inappropriate.
Northern Fur Seal Information
This National Marine Mammal Laboratory website provides links to detailed information about the distribution of fur seals in the Bering Sea region. It also features related links that lead to maps of fur seal rookeries on St. Paul Island and St. George Island, as well as PDF reports that describe fur seal population dynamics from 1993-2001.
Technology Dynamics and Transition Management
This version of the subject Technology Dynamics and Transition Management was taught in co-operation with the Harbin Institute of Technology in China. At the heart of this module lies a model of technology development from a social perspective, which will be applied to water problems in present-day China.
Simulated Laboratories and Lessons in Microbiology and Biochemistry
This chapter provides the background and selected applications of computer based investigative biology, biochemistry, genetics and molecular biology modules. These simulations can be used as a part of lecture, pre-lab work or as laboratory exercises.
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
Use PCR and a Single Hair to Produce a "DNA Fingerprint"
As a former student once commented, "PCR is the sliced bread of molecular biology". Polymerase Chain Reaction (PCR) is a process that allows an investigator to amplify a portion of a single piece of DNA into over one billion copies. We have used PCR with our Introductory Biology students to generate a simple "DNA fingerprint". This exercise will outline all the steps required to generate a DNA fingerprint for each student during two lab meetings. This article covers the background information co
Using A Molecular Marker to Study Genetic Equilibrium in Drosophila melanogaster
Using Polymerase Chain Reaction (PCR), genetic variation in a laboratory population of Drosophila is characterized. The population contains flies with two variants of a molecular marker. DNA from individual flies is amplified by PCR, generating products which are either "long" or "short" when visualized on an agarose gel. Three PCR "genotypes" (long/long, long/short, and short/short) are distinguishable and should be present in Hardy-Weinberg frequencies. The exercise requires one session for gr
What I Could Teach Darwin Using "Darwin 2000"
A laboratory to demonstrate the use of the "Darwin 2000" website to train undergraduates to use online molecular databases and analysis tools, fostering their understanding of how genes and proteins evolve.
Refraction of Light Demonstration
In this interactive activity featuring videos adapted from the Rutgers PAER Group, observe the refraction of light as it passes through transparent objects. In the first example, when a convex lens is placed in the path of parallel beams of light, the beams converge after passing though the lens. In the second example, when a concave lens is placed in the path of parallel beams of light, the beams diverge after passing through the lens. In the third example, when a rectangular piece of glass is
Learn about Winter Squash Varieties
Much of the fresh produce we enjoy is very perishable. Raspberries and figs will only last several days without refrigeration, while potatoes and winter squash can literally last for months. Run time 01:47.
