DISTILLATION HISTORY • Distilling was used as early as 3500 BC in Mesopotamia where perfume makers had developed it as a technique for isolating the scented oils of flowers and plants‚ what we know as “attar”. • Around 1100 AD wine was first distilled to make spirit by Irish monks who travelled around Europe. • The results of distillation were considered to have magical powers and this led to alcohol being called “water of life” or “usige beatha” in Gaelic‚ “eau de vie” in French

Sources of air pollution refer to the various locations‚ activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel • "Stationary Sources" as smoke stacks of power plants‚ manufacturing facilities‚ municipal waste incinerators. Power plant is also used to refer to the engine in ships‚ aircraft and other

plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration of the sensors. Finally it looks at ways of improving the functionality of such a system‚ through improved

Design‚ Construction‚ and Testing of an Inductive Pulsed-Power Supply for a Small Railgun A. Sitzman‚ D. Surls‚ and J. Mallick Institute for Advanced Technology‚ The University of Texas at Austin Abstract—Advances in high-power-density batteries have rekindled interest in using inductive store as a pulse compression system. Although these batteries are considered very power dense‚ they lack over an order of magnitude of power density to drive a deployable electric gun. However‚ one can add

Keloid Scar Treatments: Successful keloid treatment has still been an obstacle because the current treatments are far away from guarantying cure of the disease and preventing recurrence. This probably due to the lack of an extensive research to study and evaluate those treatments (Gauglitz et al.‚ 2011). There are a wide range of therapies that have been used in treating keloid and hypertrophic scars. Although most of the therapeutic options that we will cover work for both scars‚ we have to be very
