  • Thermal power plants are one of the most important process industries for engineering professionals. Over the past decades, the power sector is facing a number of critical issues; however, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways. Practicing power plant engineers not only look after operation and maintenance of the plant, but, also look after range of activities including research and development, starting from power generation to environmental aspects of power plants.

  • To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator’s license, it is necessary to know how to perform certain calculations. In reality, most of the calculations that operators at the lower level of licensure need to know how to perform are not difÞcult, but all operators need a basic understanding of arithmetic and problem-solving techniques to be able to solve the problems they typically encounter.

  • My text Technology of Biscuits, Crackers and Cookies, which was first published in 1983, with an enlarged new edition in 1991, has proved very successful and been welcomed by biscuit manufacturers worldwide. Why, then, consider producing separate manuals in the same field? The idea started, I suppose, when my partner, Pam Chance, pointed out that, as a standard reference work, my book was both too detailed and expensive for the average plant operative to use in the course of his or her work....

  • As soon as Sandra Jackson and Dina Andrews step off the train, eleven-yearold Dina expresses her desire to go on the Wonder Wheel, which has just resumed operation for another season. On their way down there, they are huckstered cheerfully from both sides of the mostly empty midway. One cry makes Sandra smile: “Hey, pretty blonde lady! Hey, you little red-headed cutie! Come on over here and try your luck! Make my day!”

  • IN CHAPTER 5 WE DISCUSSED plants’ requirements for mineral nutrients and light in order to grow and complete their life cycle. Because living organisms interact with one another and their environment, mineral nutrients cycle through the biosphere. These cycles involve complex interactions, and each cycle is critical in its own right. Because the amount of matter in the biosphere remains constant, energy must be supplied to keep the cycles operational. Otherwise increasing entropy dictates that the flow of matter would ultimately stop.

  • A systematic control design methodology is introduced for multi-input/multi-output stable open loop plants with multiple saturations. This new methodology is a substantial improvement over previous heuristic single-input/single-output approaches. The idea is to introduce a supervisor loop so that when the references and/or disturbances are sufficiently small, the control system operates linearly as designed.

  • LIFE IN EARTH’S ATMOSPHERE presents a formidable challenge to land plants. On the one hand, the atmosphere is the source of carbon dioxide, which is needed for photosynthesis. Plants therefore need ready access to the atmosphere. On the other hand, the atmosphere is relatively dry and can dehydrate the plant. To meet the contradictory demands of maximizing carbon dioxide uptake while limiting water loss, plants have evolved adaptations to control water loss from leaves, and to replace the water lost to the atmosphere.

  • Research show that RVT doesn’t has any side effect on fertility. In 200 cases of pregnancy after RVT 66% lead to neonate birth. Premature birth before 37th week happened in 27% of the cases. Abortion rate in first trimester was 16-20% like general population and second trimester abortion was 9.5% (Plante et al., 2005; Jolley et al., 2007). If the tumor volume is less than 500mm, tumor size is less than 2 cm and invasion depth of stroma is less than 2mm we can do ultraconservative operations include simple trachelectomy or extensive conization with knife. In this...

  • Taking military barracks wastewater treatment as an example, this paper presents a new concept design of a modified DEWATS system with both the horizontal subsurface constructed wetland and aquatic plants pond. Results show that this process in treating the military barracks area wastewater have many advantages such as low operation cost, simple operation and maintenance, and the effluent could meet "the urban wastewater treatment plant pollutant discharge standard" for first level Class A.

  • East and Southern Europe), India, parts of South America, Southwest U.S./northern Mexico and Australia. The operating characteristics of STPPs are relatively well matched with the intermediate and peak electricity load requirements in these regions. Two types of collectors have been used in STPPs: parabolic trough and central receiver. Electricity is generated by incorporating the solar collectors with a Rankine cycle power plant or as an add-on to a natural gas combined cycle (referred to as an ISCCS).

  • Permanganate may be applied to sites as either potassium permanganate (KMnO4) or sodium permanganate (NaMnO4). Where cost dominates over engineering factors at a site, potassium permanganate is the preferred chemical form because it is more widely available, less costly, and is available in solid form, which facilitates transport and handling. Where other factors are more important, the liquid form of sodium permangante is preferable.
