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.
This site provides an excellent experiment involving cyclic voltammetry at a gold electrode. The experiment includes a detailed introduction to the topics of electrode capacitance, electrode reactions, and flux of the electroactive species to electrode surface. Lab report guidelines and post-lab questions are included.
GEM: Greener Education Materials for Chemists
This site is a resource for green chemistry principles and literature. It provides links for making green organic experiments and teaching the principles of green synthesis. Although it does not have many links specifically to chemical analysis, it provides an extensive overview and source of information regarding the important area of green chemistry.
Dual axis moment exchange inverted pendulum
Hardware demonstration and explanation of an inverted pendulum, stabilized by two independently controlled reaction wheels connected to DC motors. Made as part of a master's thesis at the System and Identification and Control Laboratory at the University of California, San Diego.
Virtual Textbook of Organic Chemistry
This virtual textbook allows for visualization of 3D-molecular models while teaching principles of Organic Chemistry.
Economic analysis of electric energy storage
This thesis presents a cost analysis of grid-connected electric energy storage. Various battery energy storage technologies are considered in the analysis. Life-cycle cost analysis is used. The results are presented in term of incremental cost of electricity stored and discharged, in US$/kWh,Thesis (M.S.)--Wichita State University, Dept. of Electrical and Computer Engineering.,"May 2006.",Includes bibliographic references (leaves 47-49)
Soil community analysis along a salt gradient using denaturing gradient gel electrophoresis of PCR-a
Many studies of hyper saline environments have been performed, mainly on aquatic systems. However, the microbial community in terrestrial thallasohaline environments has not been studied extensively. To our knowledge, this is the first study of a natural terrestrial thallasohaline environment using polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE). We studied the great salt plains (GSP) for this purpose. The GSP is a perfect example of an extreme environment. The

Reassessment of intra- and extra-ovarian expression of growth differentiation factor-9
Mammalian ovarian organogenesis is characterized temporally by oogonial mitosis, oogonial apoptosis, rescue of germ cells via interaction with somatic cells to form primordial follicles, and entrance into meiosis. Recent studies suggest that germ cell’s activity participate in this process via the production of local regulatory factors. Growth differentiation factor-9 (GDF-9), a novel transforming growth factor-family member, is expressed in ovaries of various species as a crucial factor in ov
Analysis of honeycomb core properties under different parametric conditions for the head injury crit
There has been enormous boom in the air travel in recent times. There is increasing demand for the technological advancement nowadays towards the safety of the onboard passengers. Certification of aircrafts requires engineers to demonstrate that a head contact with any aircraft interior complies with the Head injury criteria (HIC) threshold of 1000 units specified in 14CFR 23.562, 25.562, 27.562. Analyzing injuries to the head of the occupant when it comes to contact with any aircraft cabin inte
Are women still experiencing gender discrimination in income and employment positions?
The purpose of this research is to examine the gender pay-gap and the potential factors that contribute to income inequality. Since passing the Equal Pay Act the median weekly earnings of women is still just $0.72 for every dollar men earn. To put this in context the pay-gap in 1970 was $0.62 and in 1992 it was $0.75 (Institute for Women’s Policy Research, 1993). Secondary data analysis of the 2003 American Time Use Survey purports the potential reasons why the pay-gap still continues. This re
Prediction of crack growth in aircraft engine bleed air ducts using finite element and crack growth
The bleed air system in an aircraft engine is one of the most important systems for flight operation and is the heart of the aircraft engine pneumatic system. It consists of ducts and components that supply high pressure bleed air from the engine compressor to the other systems. The functioning of bleed air system plays a vital role in flight safety, ground operations, and coordination with other existing systems  including fuel system, lubrication system, ignition system, and anti-ice system
This software can be used to investigate common molecular biology laboratory procedures using DNA or protein sequence data. These simulations and cases are based primarily on genetic and infectious disease with techniques such as: DNA electrophoresis, Southern blot, PCR, Multiplex PCR, Dot blot, ELISA, Western blot, 96-well PCR, protein electrophoresis. Case It! is collaborative BioQUEST project between the University of Wisconsin-River Falls and Michigan State University.
