China Energy Databook -- User Guide and Documentation, Version 7.0
Since 2001, China's energy consumption has grown more quickly than expected by Chinese or international observers. This edition of the China Energy Databook traces the growth of the energy system through 2006. As with version six, the Databook covers a wide range of energy-related information, including resources and reserves, production, consumption, investment, equipment, prices, trade, environment, economy, and demographic data. These data provide an extensive quantitative foundation for understanding China's growing energy system. In addition to providing updated data through 2006, version seven includes revised energy and GDP data back to the 1990s. In the 2005 China Energy Statistical Yearbook, China's National Bureau of Statistics (NBS) published revised energy production, consumption, and usage data covering the years 1998 to 2003. Most of these revisions related to coal production and consumption, though natural gas data were also adjusted. In order to accommodate underestimated service sector growth, the NBS also released revised GDP data in 2005. Beyond the inclusion of historical revisions in the seventh edition, no attempt has been made to rectify known or suspected issues in the official data. The purpose of this volume is to provide a common basis for understanding China's energy system. In order to broaden understanding …

Uncertainties in Cancer Risk Coefficients for Environmental Exposure to Radionuclides. An Uncertainty Analysis for Risk Coefficients Reported in Federal Guidance Report No. 13
Federal Guidance Report No. 13 (FGR 13) provides risk coefficients for estimation of the risk of cancer due to low-level exposure to each of more than 800 radionuclides. Uncertainties in risk coefficients were quantified in FGR 13 for 33 cases (exposure to each of 11 radionuclides by each of three exposure pathways) on the basis of sensitivity analyses in which various combinations of plausible biokinetic, dosimetric, and radiation risk models were used to generate alternative risk coefficients. The present report updates the uncertainty analysis in FGR 13 for the cases of inhalation and ingestion of radionuclides and expands the analysis to all radionuclides addressed in that report. The analysis indicates that most risk coefficients for inhalation or ingestion of radionuclides are determined within a factor of 5 or less by current information. That is, application of alternate plausible biokinetic and dosimetric models and radiation risk models (based on the linear, no-threshold hypothesis with an adjustment for the dose and dose rate effectiveness factor) is unlikely to change these coefficients by more than a factor of 5. In this analysis the assessed uncertainty in the radiation risk model was found to be the main determinant of the uncertainty category for most …

Occupational Radiation Exposure at Commercial Nuclear Power Reactors and Other Facilities 2008
This report summarizes the occupational exposure data that are maintained in the U.S. Nuclear Regulatory Commission (NRC) Radiation Exposure Information and Reporting System (REIRS). The bulk of the information contained in the report was compiled from the 2008 annual reports submitted by five of the seven categories1 of NRC licensees subject to the reporting requirements of 10 CFR 20.2206. The annual reports submitted by these licensees consist of radiation exposure records for each monitored individual. These records are analyzed for trends and presented in this report in terms of collective dose and the distribution of dose among the monitored individuals. Because there are no geologic repositories for high-level waste currently licensed and no low-level waste disposal facilities in operation, only five categories will be considered in this report.

Evaluation of the Biological Effects of the Northwest Power Conservation Council's Mainstem Amendment on the Fisheries Upstream and Downstream of Libby Dam, Montana, 2007-2008 Annual Report.
A new project began in 2005 to monitor the biological and physical effects of improved operations of Hungry Horse and Libby Dams, Montana, called for by the Northwest Power and Conservation Council (NPCC) Mainstem Amendment. This operating strategy was designed to benefit resident fish impacted by hydropower and flood control operations. Under the new operating guidelines, July through September reservoir drafts will be limited to 10 feet from full pool during the highest 80% of water supply years and 20 feet from full pool during the lowest 20% of water supply (drought) years. Limits were also established on how rapidly discharge from the dams can be increased or decreased depending on the season. The NPCC also directed the federal agencies that operate Libby and Hungry Horse Dams to implement a new flood control strategy (VARQ) and directed Montana Fish, Wildlife & Parks to evaluate biological responses to this operating strategy. The Mainstem Amendment operating strategy has not been fully implemented at the Montana dams as of June 2008 but the strategy will be implemented in 2009. This report highlights the monitoring methods used to monitor the effects of the Mainstem Amendment operations on fishes, habitat, and aquatic invertebrates upstream and …

Analysis of U.S. residential air leakage database
The air leakage of a building envelope can be determined from fan pressurization measurements with a blower door. More than 70,000 air leakage measurements have been compiled into a database. In addition to air leakage, the database includes other important characteristics of the dwellings tested, such as floor area, year built, and location. There are also data for some houses on the presence of heating ducts, and floor/basement construction type. The purpose of this work is to identify house characteristics that can be used to predict air leakage. We found that the distribution of leakage normalized with floor area of the house is roughly lognormal. Year built and floor area are the two most significant factors to consider when predicting air leakage: older and smaller houses tend to have higher normalized leakage areas compared to newer and larger ones. Results from multiple linear regression of normalized leakage with respect to these two factors are presented for three types of houses: low-income, energy-efficient, and conventional. We demonstrate a method of using the regression model in conjunction with housing characteristics published by the US Census Bureau to derive a distribution that describes the air leakage of the single-family detached housing stock. Comparison …

Empirical Tests of the Signaling and Monitoring Hypotheses for Initial Public Offerings
Access:
Use of this item is restricted to the UNT Community
The research questions investigated are: 1. Are the expected post-issue fractional holdings of the directors and officers, venture capitalists and institutions signals of firm value? 2. Are the expected post-issue fractional holdings of the directors and officers, venture capitalists and institutions signals of underpricing? and 3. Are the directors and officers, venture capitalists and institutions monitors of IPO investments? The signaling theory developed by Grinblatt and Hwang (1989) (GH) and the monitoring theory for IPO investments have been used to develop the hypotheses for this dissertation. Four factors make my methodology unique. These factors are: 1. I apply and test the GH IPO signaling model over a unique data set collected from the IPO prospectuses, proxy statements and annual reports; 2. I disaggregate the expected post-issue holdings of the different groups of pre-issue blockholders and insiders and hypothesizes that these individual groups represents signals of firm value and underpricing; 3. I hypothesize that these groups, in aggregate and separately, monitor IPO investments over the long term; And 4. I develop signaling and monitoring hypotheses to make predictions at the two stages of the IPO. The results show that firm value is positively related to the level of underpricing, at a …

Physical and Chemical Implications of Mid-Winter Pumping of Trunda Lakes - North Slope, Alaska
Tundra lakes on the North Slope, Alaska, are an important resource for energy development and petroleum field operations. A majority of exploration activities, pipeline maintenance, and restoration activities take place on winter ice roads that depend on water availability at key times of the winter operating season. These same lakes provide important fisheries and ecosystem functions. In particular, overwintering habitat for fish is one important management concern. This study focused on the evaluation of winter water use in the current field operating areas to provide a better understanding of the current water use practices. It found that under the current water use practices, there were no measurable negative effects of winter pumping on the lakes studied and current water use management practices were appropriately conservative. The study did find many areas where improvements in the understanding of tundra lake hydrology and water usage would benefit industry, management agencies, and the protection of fisheries and ecosystems.

Multiaperture U BV RIzJHK Photometry of Galaxies in the Coma Cluster
We present a set of UBV RIzJHKs photometry for 745 J +H band selected objects in a 22:5{prime} x 29:2{prime} region centered on the core of the Coma cluster. This includes 516 galaxies and is at least 80% complete to H = 16, with a spectroscopically complete sample of 111 cluster members (nearly all with morphological classification) for H < 14:5. For each object we present total Kron (1980) magnitudes and aperture photometry. As an example, we use these data to derive color-magnitude relations for Coma early-type galaxies, measure the intrinsic scatter of these relations and its dependence on galaxy mass, and address the issue of color gradients. We find that the color gradients are mild and that the intrinsic scatter about the color-magnitude relation is small ({approx} 0:05 mag in U-V and less than {approx} 0:03 in B-R, V-I, or J-K). There is no evidence that the intrinsic scatter varies with galaxy luminosity, suggesting that the cluster red sequence is established at early epochs over a range of {approx} 100 in stellar mass.

The impact of climate and flooding on tree ring growth of Fraxinus pennsylvanica in north-central Texas.
Tree cores of Fraxinus pennsylvanica were used in a dendrochronological analysis investigating the species' responses to climate and flooding. The objective was to develop a model that incorporates the effects of precipitation, temperature, and flooding on radial growth in this species in north-central Texas. The trees exhibited strong climatic signals. The study clearly shows that all three factors have significant impacts on tree ring growth both prior to and during growth; however, the nature and extent of these impacts are highly dependent on what time of year they occur. The large temporal variations in growth responses emphasize the importance of considering the timing of environmental events when studying tree growth responses.

Evaluating Tree Seedling Survival and Growth in a Bottomland Old-field Site: Implications for Ecological Restoration
In order to assess the enhancement of seedling survival and growth during drought conditions, five-hundred bare-root seedlings each of Shumard oak (Quercus shumardii Buckl.) and green ash (Fraxinus pennsylvanica Marsh.) were planted each with four soil amendments at a Wildlife Management Area in Lewisville, Texas. The treatments were a mycorrhizal inoculant, mulch fabric, and two superabsorbent gels (TerraSorb® and DRiWATER®). Survival and growth measurements were assessed periodically for two years. Research was conducted on vegetation, soil, and site history for baseline data. Both superabsorbent gels gave significant results for Shumard oak survival, and one increased green ash diameter. For overall growth, significant results were found among DRiWATER®, mycorrhizae, and mulch treatments.

Spatial and Temporal Influences of Water Quality on Zooplankton in Lake Texoma
Seventy-one aquatic species including the copepodids and nauplii were identified from Lake Texoma from August 1996 to September 1997. Zooplankton community structure, abundance and spatial and temporal distributions were compared among five lake zones delineated a priori based on chloride concentration. The zones, in order of decreasing chloride concentration, are the Red River zone (RRZ), Red river Transition zone (RRTZ), Main Lake zone (MLZ), Washita River Transition zone (WRTZ) and Washita River zone (WRZ). Bray Curtis Similarity Index showed community structure was most similar in the two Red River arm zones, the two Washita River arm zones and the MLZ. Zooplankton abundance was greatest in the Red River arm (312 org/L), intermediate in the Washita River arm (217 org/L) and least in the Main Lake body (103 org/L). A significant increase in the abundance of a deformed rotifer, Keratella cochlearis, was observed mainly in the Red River arm during a second study from March 1999 to June 1999. Seasonal dynamics, rather than spatial dynamics, were more important in structuring the zooplankton community, especially in the two river arms. Spatial variance was solely attributed to station and zone effects independent of time for a few crustacean species and many of the …

The Effects of Media Exposure on Body Satisfaction, Beliefs About Attractiveness, Mood and Bulimic Symptomatology Among College Women
The research of Stice et al. (1994) and Stice and Shaw (1994) proposed several mechanisms that may mediate the adverse effects of media exposure to the thin ideal including internalization of the thin-ideal, negative affect, and body dissatisfaction. The purpose of this study was to extend initial research of Stice and Shaw (1994) by incorporating two forms of media (e.g., TV and Magazines) to assess the effects of exposure to the media portrayal of ideal body shape on women's mood, body satisfaction, and internalization of societal values concerning attractiveness. The relation of these variables to bulimic symptomatology was examined. The current study improved upon Stice and Shaw's study (1994) by matching participants' scores on BMI, level of negative affect, and level of body satisfaction before random assignment to the experimental conditions. Female undergraduates aged 18 to 25 years participated in premeasure (N = 198) and post measure (N = 164) conditions. Results from repeated mulitvariate analysis indicated media exposure to ideal-body images demonstrated no significant changes in women's affect, body satisfaction or endorsement of the thin ideal. Indirect support for the sociocultural theory of eating disorders was provided by multiple regression analyses that demonstrated lower levels of satisfaction with size …

The Design and Analysis of Salmonid Tagging Studies in the Columbia Basin : Volume XVII : Effects of Ocean Covariates and Release Timing on First Ocean-Year Survival of Fall Chinook Salmon from Oregon and Washington Coastal Hatcheries.
Effects of oceanographic conditions, as well as effects of release-timing and release-size, on first ocean-year survival of subyearling fall chinook salmon were investigated by analyzing CWT release and recovery data from Oregon and Washington coastal hatcheries. Age-class strength was estimated using a multinomial probability likelihood which estimated first-year survival as a proportional hazards regression against ocean and release covariates. Weight-at-release and release-month were found to significantly effect first year survival (p < 0.05) and ocean effects were therefore estimated after adjusting for weight-at-release. Negative survival trend was modeled for sea surface temperature (SST) during 11 months of the year over the study period (1970-1992). Statistically significant negative survival trends (p < 0.05) were found for SST during April, June, November and December. Strong pairwise correlations (r > 0.6) between SST in April/June, April/November and April/December suggest the significant relationships were due to one underlying process. At higher latitudes (45{sup o} and 48{sup o}N), summer upwelling (June-August) showed positive survival trend with survival and fall (September-November) downwelling showed positive trend with survival, indicating early fall transition improved survival. At 45{sup o} and 48{sup o}, during spring, alternating survival trends with upwelling were observed between March and May, with negative trend occurring …

Duct leakage impacts on VAV system performance in California large commercial buildings
The purpose of this study is to evaluate the variability of duct leakage impacts on air distribution system performance for typical large commercial buildings in California. Specifically, a hybrid DOE-2/TRNSYS sequential simulation approach was used to model the energy use of a low-pressure terminal-reheat variable-air-volume (VAV) HVAC system with six duct leakage configurations (tight to leaky) in nine prototypical large office buildings (representing three construction eras in three California climates where these types of buildings are common). Combined fan power for the variable-speed-controlled supply and return fans at design conditions was assumed to be 0.8 W/cfm. Based on our analyses of the 54 simulation cases, the increase in annual fan energy is estimated to be 40 to 50% for a system with a total leakage of 19% at design conditions compared to a tight system with 5% leakage. Annual cooling plant energy also increases by about 7 to 10%, but reheat energy decreases (about 3 to 10%). In combination, the increase in total annual HVAC site energy is 2 to 14%. The total HVAC site energy use includes supply and return fan electricity consumption, chiller and cooling tower electricity consumption, boiler electricity consumption, and boiler natural gas consumption. Using year …
