While the Internet age has changed many people’s views on public libraries‚ some do not realize the important role which libraries fill. They are a place for preserving important information about history and countless other topics‚ serve all ages and demographics through their programs and resources‚ and they allow for more personal connections than electronics establish. Even though technology is evolving and improving lives in many ways‚ preserving libraries is something that cannot be looked

of potassium dihydrogen phosphate was dissolved in sufficient deionized water to produce 100 mL of solution. Solution 2: An accurately weighed quantity of 35.81 g of disodium hydrogen phosphate was dissolved in sufficient volume of deionized water to produce 100 mL. Accurately measured volume of 96.4 mL of solution 1 was mixed with 3.6 mL of solution 2 to get the activation buffer. 2. Coupling buffer (pH 8.2-8.35) An accurately weighed quantity of 0.42 g of sodium hydrogen carbonate was dissolved in

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

Synthesis of terpolymer PLGC: The terpolymer PLGC was synthesized using a reported procedure with a starting monomer ratio of 70:20:10 of L-LA‚ GL and Ɛ-CL respectively using the catalyst tin(II)2-ethyl hexanoate. The chemical reaction is given in the figure1. The yield % of the synthesized polymer was calculated by the equation: Yield %= (Weight of synthesized polymer)/(Weight of the monomers taken) ×100 Characterization of synthesized polymer: Chemical analysis using Fourier transform infrared

First‚ the synthesis of the coordination compound‚ KaFeb(ox)cdH2O‚ needed to be carried out. This was achieved by weighing out 8.29 grams of K2C2O4 with a Dial-a-gram balance. Once measured‚ the 8.29 grams K2C2O4 were placed in a 125 mL Erlenmeyer flask. 25 mL of deionized water were then added to the 125 mL flask and stirred with the K2C2O4 until complete dissolution was achieved. Next‚ 4.11 grams of FeCl3 were weighed out using the balance previously mentioned. Once the 4.11 grams were measured

Hamlet synthesis questions. Below are a list of questions we will be discussing next week (depending on your class day). You will be assigned one questions will serve both as a quiz grade AND a basis for our class discussion. This assignment has two parts: 1. A brief research portion‚ where you will paraphrase a critic’s point 2. Your own opinion of the question with at least 5 quotes to back up your position. Remember‚ we are going to look at the entire play—your response should include a discussion

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

The IR ATR spectra that was collected has a similar carbonyl stretch pattern similar in the (benzene)chromium tricarbonyl IR spectra found in the literature (figure 1)2. The stretches of the carbonyls of the chromium tricarbonyl complex at 1942 and 1833 cm-1 are near 2000
