RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before

UNSTEADY STATE HEAT TRANSFER Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems‚ design of conventional space and water heating systems‚ cooling of electronic equipment‚ and many manufacturing processes (Campos 3). Unsteady state conduction is the class of heat transfer in which the temperature of the conducting medium varies with time and position. This occurs frequently in

Free exchange Savers’ lament The complex effects of low interest rates on consumption and investment Dec 1st 2012 | from The Economist print edition WHEN interest rates hit double digits in the late 1970s‚ house-builders sent planks of wood to the Federal Reserve in protest. With rates stuck near zero‚ the protests now come from the opposite direction. The retired complain of a “war on savings”. The Fed cut rates to current levels at the end of 2008 and has promised to keep them there until

University/Funding n/a This is a review article. Summary Experiments are summarized showing that carbohydraterestricted diets are at least as effective for weight loss as low-fat diets and that substitution of fat for carbohydrate is generally beneficial for risk of cardiovascular disease. These beneficial effects of carbohydrate restriction do not require weight loss. Finally‚ the point is reiterated that carbohydrate restriction improves all of the features of metabolic syndrome.

The lazy afternoon sun plants hot kisses on the nape of my neck as I drift up the garden path and towards the house. It’s the kind of heat that dries out your skin and chaps your lips. Towing an armful of bulky paper shopping bags‚ I slip through the side gate‚ shaded by the sweet smelling jasmine that climbs up the wooden fence palings. “Monet!” I shout‚ my eyes dart back and forth‚ surveying the empty yard. A heavy silence follows. My forehead prickles with worry when no little white dog with
