INTRODUCTION The ever increasing population in the world today has led to the mounting of sewage‚ refuse and industrial waste everywhere. This waste has no place where it could be discarded and now it has found its way into the water bodies polluting the water and thereby creating a threat to the marine flora and fauna. In the environment‚ organisms are usually exposed not just to a single pollutant but rather to a mixture of these chemicals. Mumbai is one of the busiest metropolitans in the country

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

Rationale The strategy that was implemented with the kindergarteners at Ridgedale Elementary was to provide adequate practice opportunities in order to supplement the spiral mathematics’ curriculum. The study focused on providing regular review sessions and practice time for a unit based on money‚ which is a concept that had already been introduced to the students through the regular math curriculum. This strategy was chosen because the school wide math scores are lower than the other core

Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles

TOPIC 1: RATES AND CHEMICAL EQUILIBRIUM QUESTION 1: (Taken from the DoE Physical Sciences Feb-March Paper 2 2009) Antacids are used to relieve indigestion. Indigestion is the condition when the stomach produces too much acid resulting in an uncomfortable and painful feeling. A certain antacid tablet dissolves in water and reacts with the acid in the stomach to release carbon dioxide gas. 1.1 Name the type of chemical reaction that explains why antacids bring relief from indigestion

Hybrid Cars I have always wondered what Hybrid cars were all about. Especially because over the past couple of years gas prices have been at record highs. I knew that there were such things as electric cars but until this last year or so I have only seen the wealthy be able to afford to drive them. And from what I had heard about Hybrid cars was that they were over priced‚ small‚ and not so attractive cars. No wonder nobody owns them. Now I am starting to see them more often and they aren’t as
