The coming boom in Utah's school age and college age populations: state and county scenarios | 2002-09 | Population analysts have for some time anticipated a significant increase in the school age population (5 through 17 years of age) of Utah beginning around 2004 and extending for at least a decade. At this point the question is not whether the boom will materialize, but rather, the exact timing, mag... | |

Revised Utah population estimates for the 1990s | 2001-05 | Every 10 years, the U.S. Bureau of the Census conducts a population count. In the intervening years the Utah Population Es timates Committee (UPEC) annually prepares total resident population estimates for each of the 29 counties in the state. These estimates are based on methods that ut i l i z e s... | |

Immigrants transform Utah: entering a new era of diversity | 2004-05 | Utah is generally perceived as an extremely homogeneous state whose population can trace its ancestry mostly to northern Europe. Listings for surnames like Hansen, Jensen, and Christensen do fill many pages in local telephone directories throughout the state. According to census counts, the minority... | |

Fast-tracking Wasatch Front transit investments: economic and demographic impacts of a 2025 build-out | 2011 | Over the next 30 years, the Wasatch Front will significantly expand its transit network. Plans include the construction of an additional 25 miles of light rail, 76 miles of commuter rail, 227 miles of bus rapid transit, and 29 miles of mountain transportation rail line. These projects will be built ... | |

Demographic trends affecting public education in Utah | 2000-11 | Beginning in 2004 and continuing for at least a decade, the school age population (5 to 18 year olds) in Utah will increase significantly. Throughout the 1990s, the school age population in Utah grew more slowly than did the population in general so that its share in the total population declined. T... | |

Utah's place in the macro-demographics of the U.S. in the 20th century | 2006-03 | Utah has evolved from an isolated rural state of fewer than 300,000 in 1900 to a mostly urban state of 2.5 million today. This paper is an attempt to place this population growth within the context of the broadest outlines of national population dynamics over the past century. The growth and regiona... | |

Utah's demographic transformation: a view into the future | 2008 | Utah, along with the rest of the nation, is in the midst of an extraordinary demographic transformation which has far from run its course. The confluence of four major trends continues to dramatically reshape the size and composition of the national and state populations. These trends include the ar... | |

Salt Lake County's distinctive demographics: implications for the future | 2006-11 | Salt Lake County is the economic, political, and cultural center of Utah. The county is currently home to nearly 40% of Utah residents and generates about half of all jobs in the state. It remains the most populous county, with a million of the state's 2.6 million residents,2 and its daytime populat... | |

Modeling the rich combustion of aliphatic hydrocarbons | 2000 | rich combustion; aliphatic hydrocarbons; kinetic mechanism; benzene formation; high-molecular-mass aromatic compounds | A new kinetic mechanism has been developed for the formation of benzene and high-molecular-mass aromatic compounds in rich flames of aliphatic hydrocarbons. The kinetic scheme emphasizes both the role of resonantly stabilized radicals in the growth of aromatics and the standard acetylene addition me... |

State space sensitivity to a prescribed probability density function shape in coal combustion system: Joint B-PDF versus clipped Gaussian PDF | 2000 | space sensitivity; coal combustion; b-PDF mixing model; three coal-off gas; pulverized-coal research furnace | The turbulent transport of three coal off-gas mixture fractions is coupled to a prescribed joint b-probability- density-function (b-PDF) mixing model. This physical transport and subgrid joint b-PDF mixing model is used to explore the incorporation of coal off-gas compositional disparities between t... |

Modeling the vaporization of ash constituents in a coal-fired boiler | 2000 | vaporization of ash constituents; coal-fired boiler; minimizing harmful emissions; vaporization | Emissions of fine particulate and trace toxic metals are being subjected to increasing regulation. This paper addresses how the emission of these compounds can be influenced by changes in combustion conditions, particularly those selected to minimize NOx emissions. The vaporization and condensation ... |

Relationships between composition and pulmonary toxicity of prototype particles from coal combustion and pyrolysis | 2009 | toxicity; prototype particles; coal combustion; pyrolysis; health effects; coal combustion fly-ash particles | The hypothesis that health effects associated with coal combustion fly-ash particles are exacerbated by the simultaneous presence of iron and soot was tested through two sets of experiments. The first set created prototype particles from complete and partial combustion, or oxygen free pyrolysis of a... |
