Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

feathers‚ even though they weigh the same. What is this difference? The relationship between the lead and feathers is expressed by the physical property called density. Density is defined as the ratio of a substance’s mass to the volume it occupies. Density (g/mL) = Mass (g)___ Volume (mL) In this laboratory exercise‚ you will be using skills and techniques learned earlier to determine the identity of different substances. To determine the precision of your technique‚ you

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

The ‘Experiment’ by Dr Haskell portrays the unusual experiment that he conducted to compare his bare body and a Chickadees body in harsh freezing conditions. He decided to investigate it further because there was no logical explanation for a tiny bird to be able to survive in such conditions. He related his astonishment to the Bergmann’s rule‚ which states that larger animals will be found in colder climates and smaller animals will be found in warmer climates. Haskell found that the Chickadees

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental
