...Biology 100 – K. Marr (Revised Spring 2010) Lab 2. Microscopic Observation of Cells Prelab Assignment 1. Before coming to lab, read carefully the introduction and procedures of each part of the experiment. If you and your group members are not familiar with the procedure before coming to lab, you may have difficulty completing this exercise during the lab period. 2. Answer the Prelab Questions on the first three pages of the report sheet and be prepared to hand them in at the start of your lab class. Please be aware that you need to go online to answer prelab question #3. Goals of this Lab Exercise After completing this lab exercise you should be able to..... 1. Identify the parts of a compound light microscope and use a microscope to competently examine biological samples 2. Determine the diameter of the field of view for the various objectives of a microscope 3. Accurately sketch, describe and cite the major functions of the structures and organelles of the cells examined in this lab exercise 4. Estimate the size of specimens viewed with a microscope. The Microscope The microscope is one of the principal tools of the biologist. Without the microscope, many of the great discoveries of biology would never have been made. The light compound microscope, illustrated in Figure 1, is the type of microscope most commonly used. Proper, comfortable use of the instrument demands practice. The practice afforded you in this exercise depends upon familiarity with the parts of the microscope...

...UTAR FHSC1214 Fundamentals of Cell Biology Trimester 1 How YOU can do well in BIOLOGY Follow the 4A’s and you can expect A’s. A ttitude • Attend ALL lectures, tutorials and practicals on time without fail. • Be attentive in class and revise your notes after class while the topic is still fresh in your mind. Why waste time re-reading 2-3 months later? • Do your assignments faithfully as they carry marks for the finals. • Come prepared for lessons (i.e. read up beforehand). • Read up beforehand before attending lectures so that you won’t be lost and wasted hours of your life week after week. • Why stress yourself out if you can avoid it? Do NOT count on last minute revision for tests and examinations, as it will be too late to catch up and seek help in areas where you may find confusing or unclear of. • Why panic before exams because you can’t find this or that? Keep separate files for lecture, tutorial and practical. File up the respective notes systematically so that you do not lose them along the semester. • Do you expect the lecturer/ tutor to be available all the time to answer your questions? It is YOUR responsibility to take the initiative to clear your doubts or satisfy your curiosity to understand certain scientific phenomena by reading up on the relevant topics. A Based on a true story… A professor at the National University of Singapore recounts how on one occasion a student consulted him days before the exam. Student:...

...Robotic Assistants for Aircraft Inspectors Mel Siegel, Priyan Gunatilake, and Gregg Podnar Intelligent Sensor, Measurement, and Control Laboratory The Robotics Institute -- School of Computer Science -- Carnegie Mellon University Pittsburgh, Pennsylvania 15213-3891 ABSTRACT Aircraft flight pressurization/depressurization cycling causes the skin to inflate and deflate, stressing it around the rivets that fasten it to the airframe. The resulting strain, exacerbated by corrosion, drives the growth of initially microscopic cracks. To avoid catastrophe, aircraft are inspected periodically for cracks and corrosion. The inspection technology employed is ~90% naked-eye vision. We have developed and demonstrated robotic deployment of both remote enhanced 3D-stereoscopic video instrumentation for visual inspection and remote eddy current probes for instrumented inspection. This article describes the aircraft skin inspection application, how robotic deployment may alleviate human performance problems and workplace hazards during inspection, practical robotic deployment systems, their instrumentation packages, and our progress toward developing image enhancement and understanding techniques that could help aircraft inspectors to find cracks, corrosion, and other visually detectable damage. KEYWORDS: automated robot visual NDI inspection enhanced remote stereoscopic multiresolution 1. INTRODUCTION Pressurization and de-pressurization of an airplane during each takeoff and landing cycle causes...

...This will be used later to share with the group so it is essential that you accurately and neatly complete the tables or write in the spaces provided without doodling or scribbling on the pages. You will also notice there may be a series of formative questions following each section. These will help you consolidate your knowledge and some preparation towards your final course work submission and exam. Finally, keep this book clean and tidy and it will be an invaluable source of information for the next few years on your degree course. We hope you enjoy the practical sessions after all it’s what science is all about.
