Love is a difficult matter when it comes to deciding what love actually is. There are many perspectives of love, which then leads to different values and characteristics of love. Generally, it is also diverse in a sense that it can be directed in all sorts of ways including love for selves, love for others, or love for or to something. If not dealt carefully and cautiously, then sometimes love can ultimately make a person to behave obsessively, manipulatively, or self-destructing. However,…

carbohydrate-derived solid acid catalyst; method 1: sulfonation by thermal decomposition of ammonium sulphate (NH4SO4), method 2: sulfonation by thermal treatment with concentrated sulphuric acid (H2SO4), method 3: sulfonation by in-situ chlorosulfonic acid in chloroform and method 4: sulfonation by in-situ polymerisation of poly(sodium4-styrenesulphonate), method 4. Among all, sulfonation with concentrated H2SO4 is the most common method used to prepare carbon based solid acid catalyst…

English Research Paper During the Civil War over 620,000 Americans were killed, and over 1,000 soldiers were wounded at some point in the war( Civil War Statistics). That is more Americans killed than in any other war the United States has been involved in. And prior to the Civil War all wars combined did not match up with the total of lives lost in the Civil War. Contributing to that number is the fact that both sides of the war were Americans. The Civil War is the single most devastating war…

commodities, grain elevators, mills, ships, clothes…” (Cornell.edu).The names are different, but Methyl Bromide and Sodium Azide do have some similarities. For example, bromomethane, is a colorless gas which is usually odorless, but has a sweet, chloroform odor at high concentrations. It may not cause a spontaneous explosion, but it is a hazard under sparks and flames. This chemical is highly toxic to the human body causing “dizziness, vision and hearing disturbances, depression, confusion,…

radio frequency by the sample. 4. A pulse programmer and a computer which can process and present the whole data. The sample to be analyzed is dissolved in a solvent and placed in a magnetic field. The most used solvent for NMR spectroscopy is Chloroform-d (CDCl3) because A. Its solubilising character is very strong. B. It has a relatively non-reactive…

As a satellite orbits through the peaceful space it contrasts with a heavy thunderstorm on Earth. In the middle of the sea a fisherman is confronted by a giant shadow with two eyes. The Iron Giant by Warner Brothers is first introduced with a computer generated satellite animation. Then as it moves away the Earth is shown drawn in a traditional animation. It is different from the satellite because the clouds move in a way that does not seem mechanical.Like the introduction, the 2D and 3D…

The Yellow Wallpaper by Charlotte Perkins Gilman, is an example of early work of feminist literature for its illustration of attitudes toward physical and mental women’s health. The narrator of this piece is the wife of John, who is a physician. We follow her story as she is brought to an old estate by her husband due to her mental condition, which her husband labels as “temporary nervous depression-a slight hysterical tendency” (Gwynn, pg. 78). She is placed in a nursery where she is forbidden…

the relationship between solvent and polymorph nucleation in Isonicotinamide. Three (3) forms of Isonicotinamide (I, II and IV) were crystalized using solvents such as nitrobenzene, acetone, nitromethane, methanol, ethanol, 2-propanol, dioxane and chloroform. It was found that the hydrogen bonding behaviour of Isonicotinamide is of interest since different polymorphs exhibited different hydrogen bonding and molecular…

Chlorine produces a by-product group called trihalomethane and chloroform. Other by-products produced during the disinfection process are bromodichloromethane, chlorodibromethane, bromoform and etc. When these by-products were tested on lab animals many showed carcinogenic signs. In 1996-2001 more than 16 million American…

Extraction of Caffeine from Tealeaves Rosheen Villaraza, Dana Young, Dana Yu*, and Ray Zafra Department of Biological Studies, University of Santo Tomas, Manila, Philippines Abstract Experiment 3 highlights the separation of caffeine from tea leaves and using chromatography for testing its purity. Extraction is a method of separating the desired from the undesired substance in a mixture through the solubility properties of the substances. In the experimental extraction, Camellia sinensis was…
