  • In this work, non-thermal N2/Ar micro-plasma was applied to fibroblast cells and second degree burn in mice to investigate the bio-safety and bioefficiency of micro-plasma device for studying wound healing process. The chosen parameters of the device were the addition of 0.5% N2 in argon plasma and RF supplied power of 17 W and 13 W in vitro and in vivo studies, respectively

  • The business world is full of endless opportunity to make it big, or crash and burn. Small businesses crop up every day, but very few of them last to see a second anniversary, even when their basic idea was a good one. In this world, the difference between success and failure is in knowing how to work the numbers. Those who learn to unlock the secrets of financial statements win; those who muddle through and leave the numbers solely to the “numbers guys” often lose their shirts.

  • Basic knowledge of cement a), Chemical composition of cement and hydration of clinker compounds Of the above figures, Alite has the most first hydrate reaction, therefore Alite contributes considerably to short term strength and the hydrate reaction completely finishes for a few months. While the hydrate reaction speed of belite is lower. As the result, the development of the short term strength is low, but it effects the long term strength. Alite reaction with water is the most activity, and interstitial material is also high reaction with water.(see figure 1)...

  • For millennia, advances in human progress have been tied to our ability to protect ourselves from the harmful effects of the wastes we produce—ranging from human waste to the organic and inorganic by-products of everyday living. Across the world, cultures learned to bury their dead away from their homes and to burn their waste or make certain that it was carried away by streams and rivers flowing downstream from their homes. Those cultures that learned this most effectively thrived. When the industrial revolution took place in the nineteenth century, rivers again enabled progress.

  • Chemical reactions occur continuously in the atmosphere, in factories, in vehicles, in the environment, and in our bodies. In a chemical reaction, one or more kinds of matter is changed into a new kind-or several new kinds-of matter. A few common chemical reactions are shown here. Life as we know it could not exist without these processes: plants could not photosynthesize, cars could not move, pudding could not thicken, muscles could not burn energy, glue could not stick, and fire could not burn. ...

  • Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

  • AIR-HEATING PROCESSES Air can be heated by burning fuel or by recovering waste heat from another process. In either case, the heat can be transferred to air directly or indirectly. Indirect air heaters are heat exchangers wherein the products of combustion never contact or mix with the air to be heated. In waste heat recovery, the heat exchanger is termed a recuperator. Direct air heaters or direct-fired air heaters heat the air by intentionally mixing the products or combustion of waste gas with the air to be heated. ...

  • Gas–liquid multiphase flows play an essential role in the workings of Nature and the enterprises of mankind. Our everyday encounter with liquids is nearly always at a free surface, such as when drinking, washing, rinsing, and cooking. Similarly, such flows are in abundance in industrial applications: heat transfer by boiling is the preferred mode in both conventional and nuclear power plants, and bubbledriven circulation systems are used in metal processing operations such as steel making, ladle metallurgy, and the secondary refining of aluminum and copper.

  • Whether to co-process alternative fuels in cement kilns can be evaluated upon environmental and economic criteria. As is discussed in detail below, the potential benefits of burning alternative fuels at cement plants are numerous. However, the contrary is possible, when poor planning results in projects where cement kilns have higher emissions, or where alternative fuels are not put to their highest value use. Five guiding principles outlined by the German development agency, GTZ, and Holcim Group Support Ltd.

  • Mercury that exists in a stable state in the Earth’s crust is referred to as “geologic” mercury. The active mercury cycle begins when mercury is released from this stable form to the environment through natural processes or human intervention. There are four principal pathways releasing mercury to the environment. First is through natural processes; for example, mercury that was once in the Earth’s crust could be released through a volcanic eruption or other geological activity.

  • Bat guano has been composted thoroughly by the beetles and the microorganisms on the floor of the caves. However, guano from attics of buildings may not have been processed by beetles. If it still looks like mouse droppings it is not processed and should be handled with care to avoid disease exposure. Use 1-2 teaspoons per 6î pot diameter. Repeat in 4-6 weeks if necessary. In the flower and vegetable garden use 1-3 quarts per 100 square feet. However guano is a slow release fertilizer and will not burn even if using double the recommended amounts. Itís always better to...

  • Vertical shaft kilns are still used in some parts of the world to produce cement, predominately in China where they are currently used to manufacture nearly half of the cement produced annually (Wang 2007). A shaft kiln essentially consists of a large drum set vertically with a packed mixture of raw material and fuel traveling down through it under gravity. Parallel evolution of shaft kiln technology with the more complex dry process rotary kilns kept the mix of pyroprocessing technologies in China's cement industry more diverse than in almost any other country.

  • Worldwide, China is the chief consumer of coal, burning more than the United States, the European Union, and Japan combined. With worldwide de- mand for electricity, and oil and natural gas inse- curities growing, the price of coal on global mar- kets doubled fromMarch 2007 toMarch 2008: from $41 to $85 per ton. 13 In 2010, it remained in the $70+/ton range. Coal burning produces one and a half times the CO2 emissions of oil combustion and twice that from burning natural gas (for an equal amount of energy produced).

  • An emphasis on scenic beauty may lead one to devaluate that which is not beautiful—the rotted log, or the humus, or trees that have burned, blighted, or contorted, or Burnet's 'wild, vast, undigested heaps of Stones and Earth'. One wants to be able to appreciate prairies, swamps, tundras, and deserts. We start looking out for a prospect that pleases us, a pastoral scene, something that photographs well, a recreational scenic view, but we end with insight into wild processes that ignore us completely.
