Science‚ Medicine & Technology – Lecture 2 14th September‚ 2012 Global Warming – Paul Waithe * Differences between climate change & global warming: Global warming is the overall increase in the earth’s temperature. Climate change may be in either direction. For instance; more hurricanes‚ more wind etc. Comprehensive way at looking at weather patterns. * Climate change over the past century is directly linked to global warming. * Global warming could result in the world

When comparing the sample to the wet mount slides‚ they look very similar. However in the staining methods‚ the cells and their borders were very distinct while the one in the wet mounts were not as distinct. It was a bit challenging to determine the figures in the cheek smear‚ but the bacteria form in the yeast wet mount were easily recognized. The direct staining was the following technique used. The cells were very easy to assess‚ well demarcated and had a very distinctive color. Instead

1. You are looking at a Euglena using the x10 objective lens. You rotate the nosepiece around to x40 but the specimen is not visible. Describe what you should do next? Start by using the fine adjustment to attempt to focus on the Euglena. However‚ if it is still not visible‚ return to the x10 objective lens and use the fine adjustment to ensure the Euglena is as sharply focused as possible. Then‚ use the stage control to re-position the slide so the Euglena is directly in the centre of the lens.

Today you’re going to learn two things. Firstly‚ Agrimonia is a genus of a species of plant that usually lives for a maximum of 2 years and it has a history of medicinal uses ranging from treating weariness to ailments for various organs; some believed that if you placed stems of a particular species of Agrimony on someone’s head‚ they would fall asleep instantly and would not wake up until the plant was removed. Secondly‚ Agrimonia is a crust punk band from Sweden featuring members of At the Gates

Name Instructor Course Date of Submission Fresnel Lens Discovery The Fresnel lens was discovered in 1819 by a French physicist named Augustin-Jean Fresnel. He served as a commissioner of light houses under the French Government (Levitt and Theresa 1). First‚ Fresnel developed a lighting system that consisted of reflector panels placed behind oil-lamps. However‚ this proved to be inefficient since it converted just about 3% of the total light emitted into useful light‚ which was insignificant (Levitt

got Nobel prize in 1930. Write something about Raman signal‚ where does it come from? What are the implications of Raman? Raman is the inelastic scattering of light. The meaning of inelastic scattering is observable from the figure below. When an electron is excited by photons of applied light‚ it jumps from ground state to higher sates. While scattering‚ there are various possible things that might happen. To explain Raman‚ I have mentioned three of them here. From the figure delineated below‚ we
