Assessment of Planetary Protection Requirements for MARS: SAMPLE RETURN MISSIONS
by National Research Council of the National AcademiesNASA maintains a planetary protection policy to avoid the forward biological contamination of other worlds by terrestrial organisms, and back biological contamination of Earth from the return of extraterrestrial materials by spaceflight missions. Forward-contamination issues related to Mars missions were addressed in a 2006 National Research Council (NRC) book, Preventing the Forward Contamination of Mars. However, it has been more than 10 years since back-contamination issues were last examined. Driven by a renewed interest in Mars sample return missions, this book reviews, updates, and replaces the planetary protection conclusions and recommendations contained in the NRC's 1997 report Mars Sample Return: Issues and Recommendations. The specific issues addressed in this book include the following: The potential for living entities to be included in samples returned from Mars; Scientific investigations that should be conducted to reduce uncertainty in the above assessment; The potential for large-scale effects on Earth's environment by any returned entity released to the environment; Criteria for intentional sample release, taking note of current and anticipated regulatory frameworks; and The status of technological measures that could be taken on a mission to prevent the inadvertent release of a returned sample into Earth's biosphere.
Assessment of Planetary Protection Requirements for Spacecraft Missions to Icy Solar System Bodies
by National Research Council Space Studies Board Division on Engineering and Physical Sciences Committee on Planetary Protection Standards for Icy Bodies in the Outer Solar SystemNASA's exploration of planets and satellites during the past 50 years has led to the discovery of traces of water ice throughout the solar system and prospects for large liquid water reservoirs beneath the frozen ICE shells of multiple satellites of the giant planets of the outer solar system. During the coming decades, NASA and other space agencies will send flybys, orbiters, subsurface probes, and, possibly, landers to these distant worlds in order to explore their geologic and chemical context. Because of their potential to harbor alien life, NASA will select missions that target the most habitable outer solar system objects. This strategy poses formidable challenges for mission planners who must balance the opportunity for exploration with the risk of contamination by Earth's microbes, which could confuse the interpretation of data obtained from these objects. The 2000 NRC report Preventing the Forward Contamination of Europa provided a criterion that was adopted with prior recommendations from the Committee on Space Research of the International Council for Science. This current NRC report revisits and extends the findings and recommendations of the 2000 Europa report in light of recent advances in planetary and life sciences and, among other tasks, assesses the risk of contamination of icy bodies in the solar system.

Assessment of Sea-Turtle Status and Trends: Integrating Demography and Abundance
by National Research Council of the National AcademiesAll six species of sea turtles found in U.S. waters are listed as endangered or threatened, but the exact population sizes of these species are unknown due to a lack of key information regarding birth and survival rates. The U.S. Endangered Species Act prohibits the hunting of sea turtles and reduces incidental losses from activities such as shrimp trawling and development on beaches used for nesting. However, current monitoring does not provide enough information on sea turtle populations to evaluate the effectiveness of these protective measures. Sea Turtle Status and Trends reviews current methods for assessing sea turtle populations and finds that although counts of sea turtles are essential, more detailed information on sea turtle biology, such as survival rates and breeding patterns, is needed to predict and understand changes in populations in order to develop successful management and conservation plans.

Assessment of Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot Plant
by National Research Council Board on Army Science and Technology Division on Engineering and Physical Sciences Committee to Assess Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot PlantAssessment of Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot Plant reviews and evaluates the results of the tests conducted on one of the SCWO units to be provided to Blue Grass Chemical Agent Destruction Pilot Plant. The Army Element, Assembled Chemical Weapons Alternatives (ACWA) is responsible for managing the conduct of destruction operations for the remaining 10 percent of the nation's chemical agent stockpile, stored at the Blue Grass Army Depot (Kentucky) and the Pueblo Chemical Depot (Colorado). Facilities to destroy the agents and their associated munitions are currently being constructed at these sites. The Blue Grass Chemical Agent Destruction Pilot Plant (BGCAPP) will destroy chemical agent and some associated energetic materials by a process of chemical neutralization known as hydrolysis. The resulting chemical waste stream is known as hydrolysate. Among the first-of-a-kind equipment to be installed at BGCAPP are three supercritical water oxidation (SCWO) reactor systems. These particular hydrolysate feeds present unique non-agent-related challenges to subsequent processing via SCWO due to their caustic nature and issues of salt management.This report provides recommendations on SCWO systemization testing inclusive of durability testing and discusses systemization testing objectives and concepts.

Assessment of the Fate of Surrogates for Enteric Pathogens Resulting From the Surcharging of Combined Sewer Systems (IHE Delft PhD Thesis Series)
by Iosif Marios ScoullosIn the last ten years (2009-2019), flooding caused the death of over 48,000 people, and affected over 697 million people globally. This is expected to increase as a result of climate change, population growth and urbanisation. Floods can cause infections due to the release of water-borne pathogens from surcharged combined sewers and other sources of faecal contamination on urban surfaces such as concrete, asphalt, gravel, pavement, playground rubber tiles and grass. Using laboratory experiments with faecal indicator bacteria Escherichia coli, and with Bacillus subtilis spores, and MS2 bacteriophages under controlled exposure to simulated sunlight, this research contributes towards a better understanding of the environmental parameters that affect the concentration of pathogens in contaminated shallow water bodies and on different urban surfaces. Also, several sampling methods are assessed for the recovery of bacteria from flood-prone urban surfaces. This study suggests that given the sunlight conditions after an urban flood, the concentration of indicator organisms and of total suspended solids and the surface type it is possible to estimate the fate of selected pathogens. The observations and results presented in this study contribute to the development of policy-making tools for rapid implementation of appropriate measures to mitigate public health risks after flooding. This book:- highlights the relation of urban floods with water-borne diseases.-stresses for the first time the importance of urban surfaces (pavement, concrete, asphalt, etc.) on the inactivation of water-borne pathogens.-provides equations that can be used to develop policy-making tools for implementation of appropriate measures to mitigate public health risks after flooding.

Associated Production of W + Charm in 13 TeV Proton-Proton Collisions Measured with CMS and Determination of the Strange Quark Content of the Proton (Springer Theses)
by Svenja Karen PflitschThe associated production of a W boson and a single charm quark (W+c) is the only process in proton-proton collisions that directly probes the strange quark content of the proton. In this thesis, W+charm production is measured in proton-proton collisions at the LHC at 13 TeV, as recorded by the Compact Muon Solenoid (CMS) experiment. The analysis focuses on the identification of W bosons in their leptonic decay to a muon and a neutrino and charm quarks are tagged via the full reconstruction of D*-Mesons.The measured cross sections of W+c production are used, in combination with other relevant CMS results and the most precise HERA DIS data, in a QCD analysis to determine the strange quark content of the proton. The resulting strange quark distribution and suppression, with respect to the other light sea quarks, are in good agreement with those obtained in neutrino scattering experiments and extend their kinematic reach.

Associative Memory Cells: Basic Units of Memory Trace
by Jin-Hui WangThis book focuses on associative memory cells and their working principles, which can be applied to associative memories and memory-relevant cognitions. Providing comprehensive diagrams, it presents the author's personal perspectives on pathology and therapeutic strategies for memory deficits in patients suffering from neurological diseases and psychiatric disorders. Associative learning is a common approach to acquire multiple associated signals, including knowledge, experiences and skills from natural environments or social interaction. The identification of the cellular and molecular mechanisms underlying associative memory is important in furthering our understanding of the principles of memory formation and memory-relevant behaviors as well as in developing therapeutic strategies that enhance memory capacity in healthy individuals and improve memory deficit in patients suffering from neurological disease and psychiatric disorders. Although a series of hypotheses about neural substrates for associative memory has been proposed, numerous questions still need to be addressed, especially the basic units and their working principle in engrams and circuits specific for various memory patterns. This book summarizes the developments concerning associative memory cells reported in current and past literature, providing a valuable overview of the field for neuroscientists, psychologists and students.
Assuming the Ecosexual Position: The Earth as Lover
by Annie Sprinkle Jennie Klein Beth StephensThe story of the artistic collaboration between the originators of the ecosex movement, their diverse communities, and the Earth What&’s sexy about saving the planet? Funny you should ask. Because that is precisely—or, perhaps, broadly—what Annie Sprinkle and Beth Stephens have spent many years bringing to light in their live art, exhibitions, and films. In 2008, Sprinkle and Stephens married the Earth, which set them on the path to explore the realms of ecosexuality as they became lovers with the Earth and made their mutual pleasure an embodied expression of passion for the environment. Ever since, they have been not just pushing but obliterating the boundaries circumscribing biology and ecology, creating ecosexual art in their performance of an environmentalism that is feminist, queer, sensual, sexual, posthuman, materialist, exuberant, and steeped in humor.Assuming the Ecosexual Position tells of childhood moments that pointed to a future of ecosexuality—for Annie, in her family swimming pool in Los Angeles; for Beth, savoring forbidden tomatoes from the vine on her grandparents&’ Appalachian farm. The book describes how the two came together as lovers and collaborators, how they took a stand against homophobia and xenophobia, and how this union led to the miraculous conception of the Love Art Laboratory, which involved influential performance artists Linda M. Montano, Guillermo Gómez-Peña, and feminist pornographer Madison Young. Stephens and Sprinkle share the process of making interactive performance art, including the Chemo Fashion Show, Cuddle, Sidewalk Sex Clinics, and Ecosex Walking Tours. Over the years, they celebrated many more weddings to various nature entities, from the Appalachian Mountains to the Adriatic Sea. To create these weddings, they collaborated with hundreds of people and invited thousands of guests as they vowed to love, honor, and cherish the many elements of the Earth.As entertaining as it is deeply serious, and arriving at a perilous time of sharp differences and constricting categories, the story of this artistic collaboration between Sprinkle, Stephens, their diverse communities, and the Earth opens gender and sexuality, art and environmentalism, to the infinite possibilities and promise of love.
