C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

Observation on U.S. Treasury Yields Date: Oct 10‚ 2012 Introduction In this paper‚ we establish three regression models on U.S. Treasury yields with two different maturities: three-month and one-year. Model 1 is to interpret the relationship between unemployment rates and the risk-free rates‚ which we choose the three-month T-bill interest rates. Model 2 is to evaluate the movement of short-term interest rates under pure expectation theory and liquidity premium theory as well as to compare

Yield management is defined as management of the room rates to maximize the room revenue under the conditions of fluctuating demand and where the products are perishable. Jauncey.S et al (1995). According to Jones.C et.al (1993) the two basics strategies on which the yield management is emcompasses on are: “When the demand is high the emphasis must be on receiving the highest rate possible for a room‚ ie maximum revenue When the demand is low‚ and/ or late booking demand is unlikely‚ the
