The Plot of Puddinhead Wilson essays

The Plot of Puddinhead Wilson essays In the novel Puddnhead Wilson and Those Extraordinary Twins, Mark Twain wrote a good plot with some confusing parts. The novel is good and interesting and it is always interesting to read books by him because of his history here at Elmira College. I liked the plot and how things turned out and everything that led up to the climax, but I found at points that it was confusing. The book kept my interest and made me want to keep reading. The movie kept my attention because I am better with visual things rather than written. Twain is an excellent writer and this is the second book of his I have read and I like them both very much. The plot is good and has a lot to it. The plot has everything a good novel has, such as suspense, humor and villainy. The Character Valet de Chambre Tom brought a lot to the plot and made it excellent. From the beginning of the book, Valet de Chambre Tom played a major role after being switched by his mother Roxy who was a slave. It is an odd situation that I dont think has occurred much. That is what made the plot good. It makes it good because I dont want to read a book with a plot of something I have heard about or have experienced first hand. It doesnt make me want to read it because I know all about it. Parts of the book were confusing to me. It didnt hurt the plot too much but it made me not want to read the book anymore because I didnt understand where the plot was going. The ending cleared everything up. I cant exactly pick a specific thing but it seems just to be around the part where Valet de Chambre Tom sells his mom down river. Ole Marse Driscoll ll sell you down de river befo you is two days older den what you is now. (41) It was confusing because there was a lot was going on and I had to go back and re read it. Basically the story line was choppy in ...

Ringers Solution Recipe

Ringers Solution Recipe Ringers solution is a special salt solution made up to be isotonic to physiological pH. It is named for Sydney Ringer, who determined that the liquid around a frogs heart must contain a set proportion of salts if the heart is to remain to beat (1882 -1885). There are different recipes for Ringers solution, depending on its intended purpose and the organism. Ringers solution is an aqueous solution of sodium, potassium and calcium salts. Lactated Ringers solution (LR, LRS or RL) is a special Ringers solution that contains lactate and is isotonic to human blood. Here are some recipes for Ringers solution. Ringers Solution pH 7.3-7.4 7.2 g sodium chloride - NaCl0.37 g potassium chloride - KCl0.17 g calcium chloride - CaCl2 Dissolve the reagents into the reagent-grade water.Add water to bring the final volume to 1 L.Adjust the pH to 7.3-7.4.Filter the solution through a 0.22-ÃŽ ¼m filter.Autoclave Ringers solution prior to use. Emergency Veterinary Ringers Solution This solution is intended for rehydration of small mammals, to be administered orally or subcutaneously via a syringe. This particular recipe is one that can be prepared using common chemicals and household equipment. Reagent-grade chemicals and an autoclave would be preferable if you have access to those, but this gives you an idea of an alternate method of preparing a sterile solution: 9.0 g sodium chloride - NaCl (154.00 mM): non-iodized table salt0.4 g potassium chloride - KCl (5.64 mM): Morton or NOW salt substitute0.2 - 0.3 g calcium chloride - CaCl2 (2.16 mM): calcium chloride powder1.3 g dextrose (11.10 mM): granular dextrose0.2 g sodium bicarbonate - NaHCO3 (2.38 mM): baking soda  (*add last) Mix together the sodium chloride, potassium chloride, calcium chloride and dextrose solutions or salts.If salts were used, dissolve them in about 800 ml of distilled or reverse osmosis water (not tap water or spring water or water to which minerals have been added).Mix in the baking soda. The baking soda is added last so that the calcium chloride will dissolve/not precipitate out of solution.Dilute the solution to make 1 L of Ringers solution.Seal the solution in small canning jars and cook it at least 20 minutes in a pressurized steam canner.The sterile solution is good for 2-3 years unopened or up to 1 week refrigerated, once opened.
