Middle School Portal: Math and Science Pathways (MSP2)
New from The Biology Project of the University of Arizona, this online tutorial introduces the dynamic complexes of proteins, carbohydrates, and lipids that comprise cell membranes, and relates how membranes are important for regulating ion and molecular traffic flow between cells. Each section of this Web site takes the form of a multiple choice question. Answer the question correctly, and a brief explanation of each answer choice will be displayed. Answer the question incorrectly, and a short
Racial Differences in 30-Day Mortality for Pulmonary Embolism
Objectives. Previous studies reported a higher incidence of in-hospital mortality for Black patients who had pulmonary embolism than for White patients. We used a large statewide database to compare 30-day mortality (defined as death within 30 days from the date of latest hospital admission) for Black and White patients who were hospitalized because of pulmonary embolism. Methods. The study cohort consisted of 15531 discharged patients who had been treated for pulmonary embolism at 186 Pennsylv

Slipping and Rolling Wheel
The EJS Slipping and Rolling Wheel Model shows the motion of a wheel rolling on a floor subject to a frictional force as determined by the coefficient of friction ?k. The simulation allows the user to change the initial translational and rotational velocities of the wheel, v and ?, and the mass, radius, and mass distribution, R, m, and C of the wheel. By controlling these variables, the dynamics of the wheel can be changed to show the sliding, then rolling without slipping, of the wheel.

Internet Scout Project
The "Earth Observing System (EOS) Aura is a NASA mission to study the Earth's ozone, air quality, and climate" by researching the composition, chemistry, and dynamics of the Earth's atmosphere. Visitors can learn how Aura is investigating three questions: Is the Earth's ozone layer recovering? Is air quality getting worse? How is Earth's climate changing? Researchers can find extensive details about the flight, spacecraft devices and specifications, and the data processing and validation. Visito
Lecture 18 - 11/30/2010
This introductory course in "Modern Biology" covers topics found in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. This course is a requirement for biology majors at Carnegie Mellon University. The course is carefully planned to provide the background biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques curre
Molecular Stepping Stones
A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
Amplification of Biochemical Signals: the ELISA Test
Students are introduced to the role of molecular shape, weak attractions and charge in biology and biochemistry, and then undertake a simulated Direct ELISA test.
Fast Scan Voltammetry
A short presentation of theory and practice of electrochemistry focused on use of microelectrodes and micro-bands in flow cells. Problems encountered are addressed and response characteristics discussed.
Chemical Equilibria: The Law of Mass Action
Fundamental ideas and terminology of equilibria from a general chemistry perspective. A focus on closed systems, reversible chemical reactions, the law of mass action, Q and K. Also included are several multiple-choice questions that test the theories discussed. This site provides supplementary material that could be useful to beginning students in general and analytical chemistry.
Finance For New Ventures
The objectives of this course are to help students:Comprehend the process in which new business ventures are created; understand the financial aspects of the dynamics of the decision making process and day-to-day operations of a venture; become familiar with the various debt and equity sources of financing available to new and growing businesses; understand cash flow and pro forma logic and be able to apply the mechanics to income statement and balance sheet analysis and construction; apply econ
