Conical Source Transient Electromagnetic Response Characteristics With Overburden Based On Occam Constrained Inversion, Li Zhe, Yang Haiyan, Yue Jianhua, Liu Zhixin, Jiang Zhihai, Su Benyu, Zhang Hua, Wang Ling, Yang Fujie
Coal Geology & Exploration
The overburden thickness and conductivity can affect transient electromagnetic response in shallow subsurface investigation. In order to further verify the overburden detection effect with a conical source device, combining all-time apparent resistivity conversion of transient electromagnetic field, the electromagnetic response characteristics of the underlying strata influenced by the overburden was studied by introducing an Occam inversion with stratum information constraints. The results indicate that electromagnetic response intensity of the target layer is related to the resistivity ratio of the overburden to the target layer. With the overburden resistivity gradually increasing, the resistivity fitting degree between inversed data and real value …

The Play Workforce In Wales – Perceptions From Local Authority Play Sufficiency Lead Officers, Pete King, Justine Howard Dr
The Play Workforce In Wales – Perceptions From Local Authority Play Sufficiency Lead Officers, Pete King, Justine Howard Dr
International Journal of Playwork Practice
As part of the Welsh Play Workforce Study, seven lead local authority officers responsible for facilitating the three-year Play Sufficiency Assessment (PSA) were interviewed in respect of Matter G: Securing and developing the play workforce development. Thematic analysis constructed three themes from the findings: play profile, collaboration and funding. Although each lead officer was passionate about the importance of play, their play profile differed concerning their play and playwork experience, knowledge and qualifications. The study indicates the importance of collaborative and partnership working both within and external to the local authority, especially with the ever-changing play-related policy and potential funding …

Antibiotic-Resistant Escherichia Coli And EnterococcusSpp. In Sand And Water At Tampa Bay Beaches, Jennifer K. Sabater
Antibiotic-Resistant Escherichia Coli And EnterococcusSpp. In Sand And Water At Tampa Bay Beaches, Jennifer K. Sabater
USF Tampa Graduate Theses and Dissertations
As antibiotic resistance in the environment continues to rise there is an increased concern that infections may become harder to treat as bacteria acquire genes for multidrug resistance. Recreational beach waters in the Tampa Bay area are routinely monitored by the Florida Department of Environmental Protection for the presence of fecal indicator bacteria (FIB) such as Escherichia coli and enterococci. Exceedances of beach action values (BAV) 235 CFU/100 mL (E. coli) and 70 CFU/100 mL (enterococci) indicate the presence of fecal contamination which is associated with an increased risk of disease for beachgoers. Antibiotic-resistant E. coli and Enterococcus spp. have …

Assessing Environmental Sensitivity In San Diego County, California, For Bird Species Of Special Concern, Eda Okan Kilic
USF Tampa Graduate Theses and Dissertations
It is widely recognized that desertification constitutes one of the biggest environmental problems on Earth. Desertification negatively impacts the future of humans and other living things all over the globe. Therefore, the assessment of desertification is essential to both monitor and combat desertification. A number of models are routinely applied to assess desertification. The MEDALUS model is one of the most popular approaches, identifying desertification risk based on an environmentally sensitive area index (ESAI) that integrates climate, vegetation, soils, groundwater, and socio-economic factors to obtain an overall rating. The goal of this study was to measure the potential impacts of …
Influence Of Admixtures On The Performance Of Soundless Chemical Demolition Agents And Implications For Their Utilization, Nattamon Maneenoi, Raphael Bissen, Sakonvan Chawchai
Influence Of Admixtures On The Performance Of Soundless Chemical Demolition Agents And Implications For Their Utilization, Nattamon Maneenoi, Raphael Bissen, Sakonvan Chawchai
Journal of Sustainable Mining
Soundless Chemical Demolition Agents (SCDAs) are an environmentally friendly and safer alternative to traditional rock fragmentation methods. Admixtures are used to change the rheological properties and performance of SCDAs. This study aimed to investigate the effect of various concentrations of chemical accelerators (chloride salts) and viscosity enhancing agents (VEAs: Xanthan gum, Guar gum, and Gellan gum) on the fracture onset compared to an unmodified SCDA (BRISTAR 100®). All experiments were conducted on Portland Type 1 (OPC 1) cement blocks. The flowability of the mixtures was determined by mini-slump tests. Results show that 4wt% MgCl2 and 3wt% CaCl2 have accelerated the …
Population Genetics Reveals Bidirectional Fish Movement Across The Continental Divide Via An Interbasin Water Transfer, Audrey C. Harris, Sara J. Oyler-Mccance, Jennifer A. Fike, Matthew P. Fairchild, Christopher M. Kennedy, Harry J. Crockett, Dana L. Winkelman, Yoichiro Kanno

United States Geological Survey: Staff Publications
Interbasin water transfers are becoming an increasingly common tool to satisfy municipal and agricultural water demand, but their impacts on movement and gene flow of aquatic organisms are poorly understood. The Grand Ditch is an interbasin water transfer that diverts water from tributaries of the upper Colorado River on the west side of the Continental Divide to the upper Cache la Poudre River on the east side of the Continental Divide. We used single nucleotide polymorphisms to characterize population genetic structure in cutthroat trout (Oncorhynchus clarkii) and determine if fish utilize the Grand Ditch as a movement corridor. …
Effects Of Hypoxia And High Temperature On Eastern Oysters: Investigating Differential Tolerance In Populations And Ploidies, Nicholas C. Coxe
Effects Of Hypoxia And High Temperature On Eastern Oysters: Investigating Differential Tolerance In Populations And Ploidies, Nicholas C. Coxe
LSU Master's Theses
Increasing prevalence of hypoxia in estuarine waters can pose a serious threat to eastern oysters (Crassostrea virginica). While oysters are considered more tolerant to hypoxia than many other bivalves, their tolerance at temperatures of 28 °C and above, typical in northern Gulf of Mexico estuaries in the summer, is not well characterized. Moreover, it is unknown whether differences in hypoxia tolerance exist among oyster populations or between diploid and triploid oysters. To investigate population differences, wild oysters were collected from four estuaries in the northern and northwestern Gulf of Mexico and spawned. In a series of studies, the …

A Participatory Assessment Of Nitrified Urine Fertilizer Use In Swayimane, South Africa: Crop Production Potential, Farmer Attitudes And Smallholder Challenges, Benjamin C. Wilde, Eva Lieberherr, Engil Isadora Pujol Pereira, Alfred Odindo, Johan Siz
School of Earth, Environmental, & Marine Sciences Faculty Publications
Long-term nutrient mining of soil hampers agricultural production across Africa. However, emerging sanitation technologies afford a hygienically safe and ecologically sustainable solution to this development challenge by providing fertilizers derived from human excreta that could facilitate a socio-technical transition toward a more sustainable food system. To evaluate one such technology, nitrified urine fertilizer (NUF), we conducted participatory action research to assess the potential, from both a biophysical and social perspective, of NUF to serve as a soil fertilizer to support smallholder agricultural production in Swayimane, South Africa. To achieve this objective, we formed a stakeholder group comprised of a cooperative …

In late March 2018, a large part of the Eastern Mediterranean experienced an extraordinary episode of African dust, one of the most intense in recent years, here referred to as the “Minoan Red” event. The episode mainly affected the Greek island of Crete, where the highest aerosol concentrations over the past 15 yeas were recorded, although impacts were also felt well beyond this core area. Our study fills a gap in dust research by assessing the multi-sectoral impacts of sand and dust storms and their socioeconomic implications. Specifically, we provide a multi-sectoral impact assessment of Crete during the occurrence of …
