Characterization of Florida Landfills with Elevated Temperatures

The occurrence of elevated temperatures within landfills is a very challenging issue for landfill operators to detect and correct. Little is known regarding the causes of elevated temperatures (ETs) and the number of landfills currently operating under such conditions. Therefore, the goal of this research was to determine which landfills within Florida have been impacted by ETs, and to develop a more complete understanding of the factors that may lead to these landfills becoming elevated temperature landfills (ETLFs). Historical landfill gas wellhead data, waste deposition reports, and landfill site geometry were collected for 27 landfill cells through the FDEP OCULUS database and from landfill operators and owners. These data were evaluated to quantify the statistical characteristics that result in landfills becoming \u27elevated\u27 in temperature. Gas data included landfill gas temperatures, methane content, carbon dioxide content, and balance gas readings. Waste deposition information was gathered through solid waste reports for each landfill. Landfill site geometry was found through landfill permits, topographical landfill diagrams, and annual operation reports. Furthermore, landfill maps were created in ArcGIS to observe spatial distribution of ETs in landfills over time. Upon analysis of the landfill gas wellhead data, it was discovered that 74% of studied landfill cells had ET readings; regulatory limits specify a maximum allowable gas temperature of 55 degrees C (131 degrees F). When studying the solid waste reports, it was discovered that 37% of landfill cells contained MSW ash; of these cells, 90% of them are considered ETLFs. Regarding site geometry, it was found that ETLF cells are on-average double the site area and approximately 20 feet deeper than the average non-ETLF cell. Furthermore, results suggest that heat propagation in most landfills is limited; however, heat propagation is possible if gas wells are turned off for an extensive time period

Spectator Awareness and Support of Safety and Security Practices and Technologies during COVID-19

Since 2020, a global pandemic has challenged the sports industry in unprecedented ways; the industry came to a standstill at one point, eventually returning with limited capacities and public health safety and security precautions. This exploratory study examined spectators\u27 awareness and level of support for general safety and security measures and their willingness to embrace COVID-19-specific policies as they returned to live events in the U.S. in 2021. A total of 609 participants who attended a professional or collegiate sporting event within the previous three years completed the survey. Results indicated that spectators considered security measures when deciding to attend events and preferred visible measures (e.g., law enforcement presence, screening technologies, and security cameras). Spectators were willing to encounter COVID-related measures (e.g., temperature checks, digital health passes, and touchless screening) to return to live events. The most important decision-making factor in future event attendance was enhanced venue/event cleaning/hygiene protocols

Early onset of breast cancer in a group of British black women

Since there are no published data on breast cancer in British black women, we sought to determine whether, like African-American women, they present at a younger age with biologically distinct disease patterns. The method involved a retrospective review of breast cancer to compare age distributions and clinicopathological features between black women and white women in the UK, while controlling for socioeconomic status. All women presented with invasive breast cancer, between 1994 and 2005, to a single East London hospital. Black patients presented significantly younger (median age of 46 years), than white patients (median age of 67 years (P=0.001)). No significant differences between black and white population structures were identified. Black women had a higher frequency of grade 3 tumours, lymph node-positive disease, negative oestrogen receptor and progesterone receptor status and basal-like (triple negative status) tumours. There were no differences in stage at presentation; however, for tumours of ⩽2 cm, black patients had poorer survival than white patients (HR=2.90, 95% CI 0.98–8.60, P=0.05). Black women presented, on average, 21 years younger than white women. Tumours in younger women were considerably more aggressive in the black population, more likely to be basal-like, and among women with smaller tumours, black women were more than twice as likely to die of their disease. There were no disparities in socioeconomic status or treatment received. Our findings could have major implications for the biology of breast cancer and the detection and treatment of the disease in black women

Cognitive dissonance and post-decision attitude change in six presidential elections

Data from the National Election Studies were examined in an effort to isolate cognitive dissonance of two kinds: dissonance arising from a behavioral commitment in the form of voting, and dissonance arising from inconsistencies associated with having supported the losing candidate. Feeling thermometer ratings of the two principal presidential candidates obtained before and immediately after six elections (1972, 1980, 1984, 1988, 1992, and 1996) were analyzed. Regression estimates supported a dissonance reduction explanation of observed attitude changes. Voters, as compared to nonvoters, tended to increase the evaluative distance between candidates after an election, whereas supporters of the losing candidate were more likely than supporters of the winning candidate to decrease such evaluative distances. An additional examination of voters yielded results consistent with dissonance theory: After the election, respondents reporting favorable evaluations of both candidates (a difficult choice) tended to spread comparative candidate evaluations compared to respondents who were favorable toward only one candidate (an easy choice). The results both support and cast doubt on prior studies.</p

Field Investigation Of An Elevated Temperature Florida Landfill

For reasons that are not entirely clear, incidents of elevated temperatures in landfills are occurring at increasing frequency in the US. A Florida landfill has experienced temperatures that well exceed the tolerable range for microorganisms and permit standards set by the Florida Department of Environmental Protection. The landfill has experienced elevated temperatures in gas wells on the west side of the active cell. These wells were installed in 2010 in an area that received biosolids treated with incinerator fly and bottom ash. These biosolids may have caused an exothermic reaction that has interrupted methane generation. In addition to elevated temperatures (as high as 175°F), smoke, odors, hydrogen in the landfill gas, leachate color darkening, and decreased leachate generation have been observed. However, abnormal settlement has not been observed in the landfill. Preliminary data analysis of gas temperatures suggests that 20% of the wells at the landfill are impacted. Waste samples have been collected and are being analyzed. Results of waste characterization support the presence of ash in areas of elevated temperature
