Oxygen and Carbon Dioxide Analysis Systems to Enhance Laboratory Exercises in Whole Organism Biology

该项目的目的是为本科生提供应用最先进的计算机接口仪器来研究整个生物体的新体验。它允许他们通过获取和使用两个Ametek S- 3A/II氧分析仪，将Li-Cor二氧化碳分析仪升级到Li-Cor 6250标准，在生物学课程的几个层次上实施代谢研究。并购置适当的计算机和接口设备。阿美特克氧分析仪已被应用于大一生物学和三门高年级课程的代谢实验练习。这些实验室练习中有几个检验温度对生物过程的影响。仪器和计算机接口能力也丰富了独立学习和研究参与计划，这被认为是一个强大的部门必不可少的。该项目意义重大，因为它在最近生态研究和细胞与生物技术研究的仪器和方法方面取得了进步的情况下，加强了本部门在有机体一级的定量和实验经验。不同教育发展水平的学生现在可以使用质量系统，在高度实验性的环境中进行有机气体交换研究，其中仪器由计算机控制，数据在线减少和分析。受资助机构将从非联邦来源获得等额的NSF奖励。

The aim of this project is to provide undergraduates new experiences in applying state-of-the-art, computer-interfaced instruments to the study of whole organisms. It permits them to implement mebabolic studies at several levels in the Biology curriculum through the acquisition and utilization of two Ametek S- 3A/II oxygen analyzers, the upgrade of the Li-Cor CO2 analyzer to the standard of Li-Cor 6250, and acquisition of appropriate computer and interfacing equipment. The Ametek oxygen analyzers are being applied to laboratory exercises on metabolism in freshman Biology and in three upper division courses. Several of these laboratory exercises examine temperature effects on biological processes. Both instruments and the computer-interfacing capabilities also enrich independent study and research participation programs which are viewed as essential for a strong department. The project is significant because it enhances quantitative and experimental experiences at the organismic level in this department, at a time when improvements recently have been made in instrumentation and methodology for ecological studies and for cellular and biotechnological studies. Students at several levels of educational development now have access to quality systems for studies of organismic gas exchange in highly experimental settings in which instruments are computer controlled and data are reduced and analyzed on-line. The grantee institution is matching the NSF award with an equal sum obtained from non-Federal sources.
