key enzyme in NAD+ regeneration, the glycolytic flux shifts from homolactic to mixed acid fermentation with the redirection of pyruvate towards production of formate, acetate, ethanol and carbon dioxide. A mathematical model of the pyruvate metabolism pathway that enhances our understanding of ethanol production was developed from in vivo nuclear magnetic resonance (NMR) time series measurements that describes the dynamics of the metabolites in L. lactis. An S-system model based on the power law representation was able to capture the observed dynamics of the pyruvate metabolism pathway in L. lactis in vivo. The model provides insights into the maximization of selectivity
Might be Repaired through Inquiry Based Activities Gina C. Adam, Brian P. Self, James M. Widmann, Alexa Cobrun, Baheej N. SaoudIntroductionUndergraduate dynamics is often cited as one of the most difficult courses that engineeringstudents must take because many of the topics are in direct conflict with their perception of theworld around them. Newton‟s laws of motion are fundamental to the study of dynamics andstudents are particularly prone to having misconceptions drawn from their daily life interactionwith moving objects. An apple may fall from a tree to the ground faster than a leaf (althoughthey have the same acceleration in the absence of air resistance); two football players maycollide and the smaller

fatigue theory is very important to be developed in mechanical engineeringstudents. 1The fatigue strength or test data should be described by the random variables, that is, statisticalapproach. However, for undergraduate program, fatigue test data are typically described bydeveloping Stress (S) vs. average Cycles (N) to failure (S-N) curves. These curves are thefunctions of stress amplitude, mean stress and the average number of cycles at failure. Thefatigue strength of a component is significantly affected by inherent component defects andloading conditions. As such, the material strength design limit is reduced thru the application ofmodification factors, often linked with component stresses thru

Figure 2 – IEEE 754 protocol for single-precision floating point numbers [12].The exponent of the floating-point number, in contrast to IEEE’s exponent format, is also basedon 2’s compliment numbers and falls between a range of -128 and 127. Thus, the range of numbersallowed to be represented using this floating-point numbering system is -1.701412 x 103810 to1.701412 x 103810 with a resolution of 3.50325 x 10-4610.

, particularly the 1970‗s and 1980‗s, female participation in higher education inMexico was very low. This phenomenon was associated with socio-cultural stereotypes thatestablished Mexican women as mothers and wives and identified them as emotional andaffective, and therefore not ―fit‖ for schooling; this ultimately has kept them from paid workand formal education. Historically the characteristics of Mexican educational institutions havenot only affected the experiences of female students, but also have stressed traditional roles ofwomen and thus present challenges for women who venture into non-traditional fields1. Despitethis, participation of women in higher education in Mexico has increased substantially in the lastthree decades and has nearly

Science and Engineering Fairs (Evaluation)Science and Engineering (S&E) fairs are a valuable educational activity that are believed toincrease students’ engagement and learning in science and engineering by using inquiry-focusedlearning, engaging students in authentic scientific practices and engineering design processes [1-3], and emphasizing creativity [4, 5]. Proponents also argue that S&E fairs enhance students’interest in science and science careers [6, 7] as well as engineering [2]. From the fair, studentsreport that they have learned more about the scientific process and engineering design, althoughthey may not all feel their attitudes towards STEM fields has improved [2, 8]. In this paper, wefocus on science attitudes, but because

Through an analysis of the WiSE Program at USC,we hope to present a model from which others can draw on to tackle the same issues at their owninstitutions.IntroductionIn 2000, the University of Southern California (USC) launched its Women in Science andEngineering (WiSE) Program. Funded by a $20 million gift to the endowment, the goal of theprogram is to increase the number of tenured and tenure-track women faculty in science andengineering (S&E). Spearheaded by an energetic group of tenured faculty, the programs andactivities of the WiSE program have been designed to address a broad range of issues that affectthe representation of women in S&E.Operating from the Office of the Provost, WiSE works with deans and departments in the

increasing, it is not at a rate that is fast enough. This paper looks at the issues that limit engineering women‟s opportunities for faster advancement, and shares information about a course in developing leadership capacity in women engineers, documenting progress based on interviews with alumni. Significant strides are being seen in the women that understand and practice effective leadership, and organizations that can create a supportive climate for their practice.BackgroundIn the U.S., it is no longer surprising or incongruous to see a woman as principal of a public highschool, manager of a corporate department, dean of a university college, or anchor on a localnewscast. Women have breached the barriers to such positions in concert
with engineeringoutreach activities to enhance the learning experience of the students enrolled in an engineeringcourse (EGR 299 S course). The objective was to improve the retention of underrepresentedengineering students (majority at CPP) by providing them with opportunities to use theirtechnical engineering skills and by providing them with opportunities to work in diverse andmultidisciplinary teams (building confidence in their knowledge) in order to build relationshipswith K-12 students and to motivate the K-12 students to pursue STEM fields.Introduction to CPP engineering programsCal Poly Pomona is a four-year institution well-known by the diversity of its student population(0.2, 23.6, 3.3, 38.9, 0.1, 19.7, 3.9, 4.4 and 5.7 % of American
