SIM was a logical partner for our department because of their long-termcommitment to aiding developing countries and experience in supporting overseas projects.The immediate result of this trip identified a need for electrical power at a medical dispensary inthe rural village of Mahadaga, Burkina Faso. In January of 1998, a team of faculty and studentsreturned to Mahadaga to install a photovoltaic solar array. In the course of the visit, the teamdiscovered a second area for project collaboration with SIM: irrigation of the vegetable gardensand mango

The goal is to increase the number of students receiving associate and bachelor’sdegrees within science, technology, engineering and math, by conducting the following activities: 1. Development and institutionalization of two three-credit courses, one in the sciences and math, the other in engineering technologies, that emphasize academic preparation through development of laboratory techniques, communication, team work and creative thinking skills. 2. Academic year mentoring of undergraduates by teaching assistants in STEM, and block programming of the summer cohort in

notion thatmulticultural teams should be the goal when organizing project work. Students, when allowed tochoose team members, are more likely to form rather homogeneous groups. Educators cancontrol this by being more proactive in the process of not only team assignments, but in teambuilding exercises. It is likely that, with diverse student teams, two benefits accrue: (1) moreinteresting approaches to problems, and (2) students graduate better prepared to work inenvironments where multicultural groups are more the norm.C.

possible energy transformation into work.Thus, thermal energy stored at high temperatures generally is more useful to society than that available at lowertemperatures. This implies, as noted above, that thermal energy loses some of its “quality” or is degraded when it istransferred by means of heat transfer from one temperature to a lower one. Other forms of energy degradation includeenergy transformations due to frictional effects and electrical resistance. Such effects are highly undesirable if the useof energy for practical purposes is to be maximized (1-3). The second law provides some means of measuring this energy degradation through a thermodynamic termreferred to as entropy, and it is the second law (of thermodynamics) that serves

The manufacturing process will generate porous, cylindrically shapedparticles (i.e. with a characteristic height - h, and radius-R) - which will allow for diffusion onlythrough the end caps (i.e. axial, NOT radial diffusion). A local pharmaceutical companyrequests that you immobilize an enzyme that they use in the production of an antibiotic onto theinternal surface (i.e. within the pores) of the cylindrical catalyst particles. When these catalystparticles are created, it is determined that standard Michaelis Menton kinetics are observed,where:V (mol/m2 s) = Vm"[S] / Km + [S]With Vm" = 1 mol/m2 min, defined per unit of catalyst surface areaand
