...Similarly, in the second article ‘The Hazards of Household Cleaning Products' written by Janice Hughes, She argues that there are side effect of using cleaning household product. Detergents and stain removers used in our everyday life have an undesirable effect. However, Hughes did not support her claim with enough sufficient evidence. In general both articles emphasize the hazard associated with using chemical products. The author in the article ‘How Toxic Are Your Household Cleaning Supplies?' makes a better argument by giving more details and explaining how cleaning products have unwanted effects on our health and environment. The hazard of Chemicals founded in the cleaning products can lead several illnesses. Specific substances are the reason for a particular disease when used. In the article ‘How Toxic Are Your Household Cleaning Supplies?' The writer exactly describes the type of chemical used as well as diseases caused by them. For instance, they explain how ethanolamine (DEA) and triethanolamine (TEA) a substance used in cleaning products as scudding agents when react with nitrites often used as preservative can caused if used on long term cancer. In the other hand, Janice Hughes dose not exactly informs the reader what are the chemicals may cause diseases. According to her, most chemicals used in household will cause harmful effect to us....

...Chemistry Notes 2010 Core Module 1: Production of Materials Contextual Outline Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry. 1.1 Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: • Acid reactions: o acid (aq) + base (aq) salt (aq) + water (l) o acid (aq) + active metal (s) salt (aq) + hydrogen (g)...

...THE AUTOBIOGRAPHY OF BENJAMIN FRANKLIN WITH INTRODUCTION AND NOTES EDITED BY CHARLES W ELIOT LLD P F COLLIER & SON COMPANY, NEW YORK (1909) INTRODUCTORY NOTE BENJAMIN FRANKLIN was born in Milk Street, Boston, on January 6, 1706. His father, Josiah Franklin, was a tallow chandler who married twice, and of his seventeen children Benjamin was the youngest son. His schooling ended at ten, and at twelve he was bound apprentice to his brother James, a printer, who published the "New England Courant." To this journal he became a contributor, and later was for a time its nominal editor. But the brothers quarreled, and Benjamin ran away, going first to New York, and thence to Philadelphia, where he arrived in October, 1723. He soon obtained work as a printer, but after a few months he was induced by Governor Keith to go to London, where, finding Keith's promises empty, he again worked as a compositor till he was brought back to Philadelphia by a merchant named Denman, who gave him a position in his business. On Denman's death he returned to his former trade, and shortly set up a printing house of his own from which he published "The Pennsylvania Gazette," to which he contributed many essays, and which he made a medium for agitating a variety of local reforms. In 1732 he began to issue his famous "Poor Richard's Almanac" for the enrichment of which he borrowed or composed those pithy utterances of worldly wisdom which are the 1 basis of a large part of his popular reputation...

...Learning with Cases INTRODUCTION The case study method of teaching used in management education is quite different from most of the methods of teaching used at the school and undergraduate course levels. Unlike traditional lecture-based teaching where student participation in the classroom is minimal, the case method is an active learning method, which requires participation and involvement from the student in the classroom. For students who have been exposed only to the traditional teaching methods, this calls for a major change in their approach to learning. This introduction is intended to provide students with some basic information about the case method, and guidelines about what they must do to gain the maximum benefit from the method. We begin by taking a brief look at what case studies are, and how they are used in the classroom. Then we discuss what the student needs to do to prepare for a class, and what she can expect during the case discussion. We also explain how student performance is evaluated in a case study based course. Finally, we describe the benefits a student of management can expect to gain through the use of the case method. WHAT IS A CASE STUDY? There is no universally accepted definition for a case study, and the case method means different things to different people. Consequently, all case studies are not structured similarly, and variations abound in terms of style, structure and approach. Case material ranges from small caselets (a few paragraphs...
