It begins with an outline of current mining methods and innovative methods being tested by OSM, including using drill cores to assess problem strata, isolating those strata, designing and constructing weep berms, and reestablishing hardwood forests. Weep berms are described as engineered earthen structures that slowly discharge passively to downstream forests. Case studies are presented showing weep berms effectively control sediment and meet water quality standards.
Matt MacConnell, Lehigh River Stocking Association, “Lausanne Tunnel Remediat...Michael Hewitt, GISP
The Lausanne Tunnel in Jim Thorpe was installed in 1906 to dewater the coal fields in this area. The tunnel discharges about 6000 gal/min of drainage that is relatively high in iron and manganese but fortunately, the pH is relatively high and aluminum content is low. The remediation installed in 2004 was a two part passive wetland system that has been the focus of the conservation efforts by a number of conservation organizations since that time. My involvement has been to engage the local Sierra Club as well, the local trout stocking clubs and other organizations to provide funding and manpower for upgrades at the site. In 2007, two 5ft rectangular weir flow monitors were installed, one in the wetland and the other in the bypass flow, which consists of 2/3rd of the tunnel discharge flow. Pressure transducers and solar powered data loggers were installed to record both flows so that further hydrological engineering could be applied to optimize the wetland treatment while also devising a treatment plan for the bypass flow. In 2011, artesian aerators were added to the feeder pipes to improve aeration of the water entering the wetland. The aerators, however, did consume some of the available head pressure and reduced wetland feed flow so in 2014 a 3rd 14” feeder pipe was excavated and installed bringing the wetland flow rate back to the 1800 gal/min design rate. In 2016, a solar powered compressor was installed with two aerator heads added to the wetland to further boost dissolved oxygen. Iron test kits and dissolved oxygen monitors have been used to evaluate the iron removal effectiveness of the wetland and the extent of oxygen saturation. The next steps at for further improvement are the installation of cascading settling basins in the bypass flow as well as optimization of the wetland flow distribution. This presentation will feature presentation of technical flow and composition data as well as drone video of the site.

Next steps include finalizing the preliminary design, another public meeting, final design, construction anticipated in 2017-2018, and ongoing maintenance after completion.
Tyler Hall has over 5 years of experience as a civil engineer specializing in stormwater design, traffic impact assessments, and coastal engineering projects. He has extensive experience modeling stormwater networks, designing water and sewerage infrastructure to comply with FNQROC standards, and preparing supporting documents for development applications. Some of his recent projects include stormwater designs for residential subdivisions in Mossman and Caloundra, drainage assessments along Nicklin Way and in Mooloolaba, and coastal structures in Eudlo Creek, Sunshine Cove, and Mooloolaba Beach.
Dwindling availability of water, combined with increases and competition in demand, climate change impacts, trends toward true cost water pricing, among other “drivers,” necessitates that urban water planning incorporate consideration of strategies for use, conservation, and reuse of treated wastewater and stormwater. Three innovative initiatives will be discussed as illustrations of “win-win” approaches that achieve effective water management (urban water security/sustainability) while facilitating economic development.

- Liquid and solid waste streams generated during unconventional gas extraction in Appalachia include flowback water, drilling muds and cuttings.
- Flowback water contains high levels of inorganics like salts as well as organics like benzene and has total dissolved solids over 70,000 mg/L.
- Drilling cuttings can be radioactive and leach metals like barium, arsenic and lead that exceed drinking water standards.
- Proper management of wastes through practices like recycling, lining of pits and containment is needed to reduce risks to the environment and human health.
This document provides an overview of the historical and political context of energy regulation in the United States. It discusses the emergence of hydraulic fracturing and how the EPA has regulated air emissions from shale gas operations over time. The EPA has proposed new rules in 2015 to add methane standards and expand coverage to more oil and gas sources to help reduce methane emissions and meet President Obama's climate change goals. The proposed rules and regulatory approach will likely generate comments and litigation from industry and environmental groups.
This document summarizes and compares three health studies on shale gas development and human health outcomes. The studies found some associations between shale gas activity and increased hospitalization rates, higher reports of dermal and upper respiratory conditions, and certain birth defects. However, the studies have limitations like lack of direct exposure measures, potential reporting biases, and inability to rule out other contributing factors. Overall, more research is still needed to better understand potential health impacts.
This document discusses various technologies for treating unconventional oil and gas wastewater, specifically flowback and produced water. It outlines six main categories of water treatment - bulk filtration, lime softening, sulfate addition, nanofiltration, reverse osmosis, and thermal technologies. For each category, it explains what contaminants the treatment removes. The document also discusses challenges with reverse osmosis including high reject rates as salt concentrations increase. It provides an overview of other desalination technologies like membrane distillation, electrodialysis, and various thermal processes. In summary, while many technologies are used conventionally, few have proven effective for treating oil and gas wastewater at scale, with limited cost and performance data from field applications
This document summarizes environmental challenges and regulations related to oil and gas production. It discusses issues at the federal level like endangered species protections and methane emissions standards. It also examines state legislative actions and regulations in Pennsylvania, Ohio, West Virginia, Kentucky, Virginia and Illinois governing hydraulic fracturing, water management, spill prevention and well permitting requirements. The document concludes that environmental activism is high in the Appalachian Basin and Midwest, requiring state regulators to impose strict rules on industry operations.
This document discusses the potential use of RISKGATE, a risk assessment framework originally developed in Australia, to address environmental issues associated with mining.

This document summarizes a study on the leachability of elements from hydraulic fracturing residuals. The study involved collecting representative samples of residuals, identifying elements of concern, conducting leaching tests using different solutions, and analyzing the results. Key findings include that alkali metals, alkaline earth metals, and halides leached at high concentrations. Transition metals and metalloids generally leached at low or trace levels. More elements leached in more aggressive solutions. Disposal practices may require treatment of residuals before landfilling to prevent groundwater contamination.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
