Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Aldosterone and Hormone Replacement Therapy Aldosterone falls in the class of hormone called mineralocorticoids‚ produces by the adrenal glands and is found near the kidneys. It sustains blood pressure‚ water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls‚ there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering

We also put some Styrofoam cup at the back of our boat with the propeller that we have so that the wind will have more force and we put some acetate to make the Styrofoam still. * Feel free on making your own design. Just reserve a place where you can place the electric motor and secure it with tape. Battery is a heavy piece; it must be centered in order for your boat to have a balance on water

Introduction Bill Gates‚ founder of Microsoft‚ said‚ “It’s fine to celebrate success‚ but it’s more important to heed the lessons of failure. How a company deals with mistakes suggests how well it will bring out the best ideas and talents of its people‚ and how effectively it will respond to change.” This quote definitely applies to Colleen Klein’s company Chipco. “Chips‚” as Ms. Klein is common known‚ invented a 3-way mirror for the application of eye make-up: The Eye Maker.

CHAPTER ONE 1.0 INTRODUCTION 1.1 Antimycobacterial Studies An Antimycobaterial is a substance that kills or inhibits the growth and activities of disease causing Mycobacteria (e.g.‚ Mycobacterium tuberculosis‚ Mycobacterium Leprae‚ etc) that are responsible for fatal diseases such as Tuberculosis and leprosy. Antimicrobacterials can either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic) (Hannan et al.‚ 2011). Mycobacterium is a genius in the family of the Mycobacteriaceae
