Nomenclature of Aromatic Compounds Aromatic Compounds- possess a ring shaped structure Benzene (C6H6)- aka. naphtha - unsaturated cyclic compound - simplest aromatic HC - all C to C bonds are identical; each C has a H atom - substitution reactions occur instead of addition reaction - delocalized pi bonding in benzene imparts stability (aromaticity); responsible for resistance to addition reactions (involve breaking delocalized bonding) Benzene Derivatives- produced when one or more H atoms on benzene

These rings had a high proportion of earlywood and consequently wood of comparatively low density. The ring structure of the trees taken from the Dukuduku trial‚ on the other hand‚ exhibited well-defined rings across the entire radius‚ together with numerous false rings. Resin tails extending upwards and downwards from the knot is a common feature in P. caribaea and were quite common in

hit the third ring on the circle and the voltage that was recorded was 91.5V. Once the voltage was recorded the next objective was to find the value of the magnetic field. The current value that went along with circle number three was 3.08A and to find the B value the equation B=(8/sqrt(125))(μ0NI/R) was used. The B value for the third circle was computed to be 3.17x10-3T. The next step in the experiment was the radius for the electron beam‚ to do this the equation r=(.25x10-2m)(ring number) was used

Martin Luther King "I Have a Dream" When thinking of the most effective and well known speeches in history‚ one of the first speeches that comes to mind is Martin Luther King Jr.’s "I Have a Dream." A large part of Martin Luther King Jr.’s success as an orator was due to his uses of rhetoric in his speeches. King also was able to judge the mood and tone of his audience‚ and was able to interact with his audience accordingly. The uses of metaphors‚ anaphora and his ability to interact with his audience

measured the concept based on year 2000 U.S. Census data.[8] Other ways of measuring the concept with more detailed rings around the CBD include a 2001 article by Edward Glaeser[9] and Elizabeth Kneebone’s 2009 article‚ which show that sprawling urban peripheries are gaining employment while areas closer to the CBD are losing jobs.[10] These two authors used three geographic rings limited to a 35-mile (56 km) radius around the CBD: 3 miles (4.8 km) or less‚ 3 to 10 miles (16 km)‚ and 10 to 35 miles

Saguaro Federal has mainframes for all of its banks and businesses. Must the company use the Ethernet or Token Ring protocol? Explain your choice. Why is this choice appropriate? I would say Ethernet. Saguaro Federal should most definitely use Ethernet to connect to its Mainframes‚ and Servers‚ mostly because of its speed‚ security and reliability. I would run Fiber Optic cabling using 1000Base-sx‚ throughout the Saguaro Federal office. This will set them up for the fastest network connectivity

Tire ring is set in the kiln shell‚ between it and the kiln shell is not fixed‚ rotary kiln shell and tire ring plus a piece of iron between the separated ring and the tire to retain a certain gap between the kiln shell‚ not too much not too small.

Since the beginning of the early 20th century‚ the earths mean surface temperature had increased by around 0.8 degrees.

exists in the ring configuration. Messages are transferred from one computer to the next until they reach their intended destinations. Each computer on the ring topology has a particular address. As the messages pass around the ring‚ the computers validate the address. If the message is not addressed to it‚ the node transmits the message to the next computer on the ring. This type of network is commonly used in systems that connect widely dispersed mainframe computers. A ring network allows
