Steam Locomotives were first made in the 18th century. William Murdoch first made a prototype in 1784. An early working model was built by a steam boat pioneer John Fitch. Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer from Cornwall. Born in the mining heartland of Cornwall‚ Trevithick was immersed in mining and engineering from a young age. The son of a mining captain‚ he performed poorly in school‚ but went on to be an early pioneer in steam-powered

Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names‚ each representing the phases that it undergoes (chromosomes‚ chromatin‚ genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase‚ so that mitosis can make new cells‚ repairing and allowing for growth in the body. It is

Processes Conversion of Heavy Residues Treatment of Refinery Gas streams INTRODUCTION: Oil refining is a key activity in the CPI. Over 600 refineries worldwide have a total annual capacity of more than 3500 x 106 tonnes. Goal of oil refining is twofold: i. production of fuels for transportation‚ power generation and heating; and ii. production of raw materials for the CPI. Oil refineries are complex plants but are relatively mature and highly integrated.

Experiment 4: Isolation of Essential Oils from Eugenol Background: Anyone who has walked through a forest or who enjoys the variety of fragrances that flowers have to offer knows that many plants and trees have their own distinctively pleasant odors. These odors are due to the volatile essential oils‚ many of which have been prized commodities since ancient times. If a list of commercially important essential oils was compiled the list would exceed 200 essential oils. Thyme‚ garlic‚ peppermint‚ and

Earliest steam engine was designed and built by a British inventor‚ Thomas Newcomen which was used in mines to pump water that helped the worker to dig deeper and deeper. Steam engine was later redesigned and improved by James Watt. “James Watt‚ the Scottish mechanical engineer and inventor‚ whose inventions played an important role in Industrial revolution”. His redesign on steam engines was used in many other industrial machines such as steamboats and rail roads. When steam engines were redesigned

Introduction Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction‚ solid-liquid extraction and chemically active extraction. All three types of extraction follow the same principle. Organic molecules dissolve in organic solvents and polar molecules dissolve in aqueous solvents. This phenomenon is observed because of the intermolecular forces between
