NEIL DEMELLO CONTROLLED ATMOSPHERE INTRODUCTION HISTORY The concept of controlled atmosphere for prolonging the life of fresh products (commodities and fruit)‚ stored in bulk‚ dates back to World War I. As early as 1917‚ the Government‚ concerned about the food shortages during the World War‚ established the Food Investigation Organization (FIO). A leading fruit farmer pointed out the extensive spoilage of apples in storage as one of the major problems‚ to the Government. One Franklin

Dominic Vawdrey Aircraft systems essay Atmosphere The term atmosphere is described by Wikipedia as “An atmosphere (New Latin atmosphaera‚ created in the 17th century from Greek ἀτμός [atmos] "vapor" and σφαῖρα [sphaira] "sphere") is a layer of gases that may surround a material body of sufficient mass and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration‚ if the gravity is high and the atmosphere’s temperature is low. Some planets consist mainly

Atmosphere Homework Describe the composition of the air Air is a mixture of gases and aerosols that compose the atmosphere surrounding Earth. The primary gases of air include nitrogen (78%) and oxygen (21%). Trace gases and aerosols make up the remaining 1% of air. The trace gases include the noble gases argon‚ neon‚ helium‚ krypton and xenon‚ hydrogen and the greenhouse gases. The aerosols are solid or liquid particles having diameters in the region of 0.001 to 10 microns‚ and include dust

Composition of the Atmosphere The Earth is surrounded by air—a mixture of various gases that reaches up to a height of many kilometers. This envelope of air makes up our atmosphere. It is held in place by the Earth’s gravity. Almost all the atmosphere (97 percent) lies within 30 km (19 mi) of the Earth’s surface. The upper limit of the atmosphere is at a height of approximately 10‚000 km (about 6000 mi) above the Earth’s surface—a distance that is nearly as large as Earth’s diameter. The proportion

its small gravity)‚ it has no substantial atmosphere. Its extremely thin atmosphere mostly consists of a small amount of helium and traces of sodium‚ potassium‚ and oxygen. These gases derive from the solar wind‚ radioactive decay‚ meteor impacts‚ and breakdown of Mercury’s crust. Mercury’s atmosphere is not stable and is constantly being refreshed because of its atoms escaping into space as a result of the planet’s heat. The earths atmosphere compared to mercury is much MUCH better in terms of protection

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen

"The Reluctant Security Guard" By: Jennifer Ruddell AIU December 10‚ 2004 In the case of "The Reluctant Security Guard"‚ I do believe that the security guard took the correct action regarding putting drunk drivers out of the mall parking areas onto the highway. I would have‚ in this situation‚ acted in a similar manner as he. By this I mean I would have contacted my superiors and spoke of alternatives other than putting intoxicated drivers on the highway that may cause harm to others as a result

Vivid Atmosphere: Tennis Slowly‚ I kneel down to tie my shoe for the fourth time this match. The sweat creeps down my face as if mocking me in saying that I should have taken the cardio sessions more seriously. At this point I was doing everything I could just to keep my body from collapsing to the ground. The feel of the sun beating down makes me wonder if it is purposely driving all of its energy to sap mine. Glancing up across the court I see my water bottle filled with mountain dew. At that
