Abstract:
Promoting a better understanding of the phenomenon of colonization and its connection with environmental knowledge and technology, this article proposes a reframing of research agendas to take into account the municipal character of colonization in the Hispanic realm and to ask new questions. Questions should address what human–ecosystem relations, and the ways of knowing and techniques for transforming the physical realm, can tell us about colonization itself; who the historical agents involved were, and what these actors knew, learned, and did in their environments. Using the Basin of Mexico’s drainage and the agency of commoners, this article proposes that colonization depends on the massive deployment and generation of tacit knowledge about how to harness matter, energy, and time for the reproduction of human societies; the quotidian appropriation and reworking of autochthonous knowledge, techniques, and technology by the colonizing groups; the collaboration of the local populations in whom these are vested; and the agency of commoners with practical skills, environmental knowledge, and technological savvy derived from and honed in the realm of material production. In the Ibero-American realm, these agents were primarily commoners with skills in agropastoral production and the building trades; race, ethnicity, language, and gender were secondary conditions.

Abstract:
AbstractSubmesoscale oceanic density fronts are structures in geostrophic and hydrostatic balance, which are prone to inertial and/or symmetric instabilities. We argue in this article that drainage of potential energy from the geostrophic flow is a significant source of their growth. We illustrate our point with two-dimensional Boussinesq numerical simulations of oceanic density fronts on the f plane. A set of two-dimensional initial conditions covers the submesoscale portion of a three-dimensional parameter space consisting of the Richardson and Rossby numbers and a measure of stratification or latitude. Because we let the lateral density gradient decay with depth, the parameter space map is nontrivial, excluding low-Rossby, low-Richardson combinations. Dissipation and the presence of boundaries select a growing mode of inertial–symmetric instability consisting of flow cells that disturb isopycnal contours. Systematically, these isopycnal displacements correspond to a drainage of potential energy from the geostrophic fronts to the ageostrophic perturbations. In the majority of our experiments, this energy drainage is at least as important as the drainage of kinetic energy from the front. Various constraints, some physical, some numerical, make the energetics in our experiments more related to inertial rather than symmetric instabilities. Our results depend very weakly on the Richardson number and more on the Rossby number and relative stratification.

Abstract:
Microbial fuel cells (MFCs) harness the natural metabolisms of microbes to produce electrical power from almost any kind of organic matter. In addition to the low power densities (about 1mW for a 1-liter reactor), MFCs are presently built with expensive membrane and electrodes. The payback time of MFCs is therefore very long (evaluated to 25000 years for our lab prototype). Progresses in designing low-cost MFCs are necessary before conceiving large scale energy production.

Abstract:
As of today, the development of energy efficient and recycling technologies seems to be urgent. This article considers the problem of recycling of wastes in roofing industry, which is a serious environmental contamination source and creates a significant fire hazard. We have made an attempt to create a new drainage material from roofing waste. This material has the appearance of fibrous board, which is made of trimmings of bitumen-impregnated roofing roll materials thermally bonded in contact points. The technological scheme of the producing of the material was developed. The material was tested to determine its physical and mechanical properties (tensile and compressive strength, water permeability and porosity) and to optimize its technological parameters. According to the results of the experiment it was founded that the material has sufficient physical and mechanical properties, meets the technical requirements for drainage materials and can be recommended for use in underground construction.

Abstract:
In South Africa, being the second largest global coal exporter, coal mining plays a pivotal role in the growth of our economy, as well as supplying our nation’s ever increasing electricity needs; while also accounting for more than 10% of the 20 x 109 m3 water used annually in the country. Coal mining may thus be classified as a large-scale water user; known to inevitably generate wastewater [acid mine drainage (AMD)] and other waste material, including fly ash (FA). Current and conventional AMD treatment technologies include precipitation–aggregation (coagulation/flocculation) – settling as hydroxides or insoluble salts. The process stream resulting from these precipitation processes is still highly saline, therefore has to undergo secondary treatment. The best available desalination techniques include reverse osmosis (RO), electro dialysis (ED), ion exchange and evaporation. All available treatment methods associated with raw AMD and its derived process stream fall prey to numerous drawbacks. The result is that treatment is just as costly as the actual coal extraction. In addition, remediation only slows the problem down, while also having a short lifespan. Research conducted into converting fly ash, an otherwise waste material, into a marketable commodity has shown that direct mixing of known ratios of FA with AMD to a pre-determined pH, erves a dual purpose: the two wastes (AMD and FA) could be neutralized and produced a much cleaner water (secondary co-disposal [FA/AMD]-process water), broadly comparable to the process water derived from precipitation-aggregation treated AMD. The collected post process solid residues on the other hand, could be used for production of high capacity ion exchange material (e.g. zeolite A, faujasite, zeolite P, etc.). The produced ion exchange material can subsequently be utilized for the attenuation of metal species in neutralized FA/AMDprocess waters.

Abstract:
ABSTRACT In modern period, we require harnessing of energy from various possible opportunities in the living world, as non- renewable energy sources are limited and getting depleted day by day which need conservation and some new methods of unconventional energy resources for future. There is ample amount of energy available in the environment. But it is necessary the focus should there. The energy is available in the flowing water and the power was generated in the large amount but in this project the focus had been given on the harnessing energy from low amount of water. The elementary idea of the project i.e. harnessing energy from drainage system by using a cross flow pico-turbine. Which have usually minimum of i.e. a head of about .25 to 0.5 m for the discharge of the water coming out through the drainage system or the general irrigation systems . So in this project work the idea has been kept on focus that the energy must be harnessed whatever small amount that is it may be from 0.1 W -10 W. So two small size runner diameter 225 mm and the width 100 mm, which are identical but in opposite blade type was assembled on a frame so that they can be installed in a open channel of irrigation system or the municipal drainage system channel. But there must be some flow velocity available. In experiment the discharge was controlled by the sluice gate and the head was calculated with the upstream and down stream heads. The supply of water was done on a recirculation type experimental setup. The rpm of rotation was measured by using digital tachometer (rpm measuring device) and the torque was measured by rope brake dynamometer. Thus using this actual power was calculated and hence efficiency of the system was calculated. The results of this project are not much interesting in testing the generated power was of an amount of .01 W. Since there was a heavy friction whose order was 2 W was present in the model. But it was observed that very small size turbine can be installed in the system where the head available is .5 m – 10 m and discharge from 2 litre/s to 50 lit/ sec. The most advantageous thing about this project is that the cost of installation is very low. It is economical for a common man. The cost of the whole project is around Rs. 2000-5000. Not only this but also the method of installation of the project is very easy. The vi system is completely pollution free and it is not dangerous in operation as it is a small system.

Abstract:
Although the US health care system offers the very best care to many, the poor and uninsured typically face challenges in accessing timely health care, even when faced with a life-threatening disease such as cancer. Spurred by unmet patient needs and the growing complexity of health care delivery systems, patient navigation seeks to diminish social, economic, cultural, and medical system barriers to timely quality care. This case study discusses the emergence of patient navigation as a strategy for improving cancer outcomes, especially among vulnerable populations. It explores challenges and opportunities related to advancing successful implementation of patient navigation across the cancer care continuum. It seeks to harness and apply the power and energy of patient navigators with the goal of guiding individuals across the health care continuum—from the communities where they live all the way through screening, diagnosis, and treatment at clinical care sites.

Abstract:
Chapter 6 looks at the world of official urban planning and placemaking, providing different perspectives on its relationship to DIY urbanism. Through the voices of professional planners, the chapter explores their conflicted opinions on DIY approaches: criticizing their informality and emphasizing the importance of regulations and accountability for everything from basic functionality to social equity, yet sympathetic to do-it-yourselfers’ frustrations and often excited to adopt their tactics, harness their energy, and exploit their cultural value. The chapter then describes how some DIY projects have found pathways to formal adoption and inspired popular “tactical urbanism” and “creative placemaking” approaches to public space design. Many such interventions can result in innovative public spaces with social, environmental, and economic benefits. But the reproduction of an aesthetic experience selectively inspired by a hip grassroots trend and combined with “creative class” values can mark the resulting spaces themselves as elite and exclusionary.

Abstract:
This book explains how China’s new foreign policies like the vaunted “Belt and Road” Initiative are being shaped by local and regional politics outside China and assesses the political implications of these developments for Eurasia and the United States. It depicts the ways that President Xi Jinping’s China is zealously transforming its national wealth and economic power into tools of global political influence and details these developments in South Asia, Central Asia, and the Middle East. Drawing from extensive interviews, travels, and historical research, it describes how perceptions of China vary widely within states like Pakistan, Kazakhstan, and Iran. Eurasia’s powerful and privileged groups often expect to profit from their connections to China, while others fear commercial and political losses. Similarly, statesmen across Eurasia are scrambling to harness China’s energy purchases, arms sales, and infrastructure investments as a means to outdo their strategic competitors, like India and Saudi Arabia, while negotiating relations with Russia and America. The book finds that, on balance, China’s deepening involvement will play to the advantage of regional strongmen and exacerbate the political tensions within and among Eurasian states. To make the most of America’s limited influence along China’s western horizon (and elsewhere), it argues that US policymakers should pursue a selective and localized strategy to serve America’s aims in Eurasia and to better compete with China over the long run.

Full text
Abstract:
Radiotherapy has a major role in symptom control and over 40% of all radiation treatments are given with palliative intent. In the palliative setting, radiotherapy will usually be delivered using high-energy external beam treatment from a linear accelerator. Bone metastases may be treated with intravenous systemic radioisotopes and dysphagia with endoluminal brachytherapy. A general principle of palliative radiotherapy is that it should be delivered in as few treatment visits as possible and be associated with minimal acute toxicity. The main indications for palliative radiotherapy are in the management of symptoms due to local tumour growth and infiltration. These include pain from bone metastases, visceral pain from soft tissue metastases, and neuropathic pain from spinal, pelvic, and axillary tumour. Local pressure symptoms are particularly onerous and potentially dangerous when they affect the nervous system; thus spinal canal compression remains one of the few true emergency situations in which radiotherapy is indicated. Similarly brain, meningeal, or skull base metastases require urgent assessment and can be helped with local radiotherapy. Obstruction of a hollow tube or drainage channels can lead to significant symptoms and again local radiotherapy can be valuable in addressing this scenario. Such indications would include dysphagia, bronchial obstruction, leg or arm oedema, vena cava obstruction, or hydrocephalus. Finally haemorrhage can be distressing if rarely life-threatening. Local radiotherapy to bleeding tumours in the lung, bronchus, bowel, genitourinary tract, and skin is very effective at control of bleeding.

Abstract:
AbstractThe future sustainable built environment focuses mainly on environmental conservation and technological innovation and development. However, with infrastructure development, the consumption of raw materials such as cement, gypsum, sand, and stones increases. Therefore, use of industrial waste as raw material in construction shall be proposed as a sustainable and environment friendly alternative. Also, the higher demand for mineral commodities have led to increased mining and hence increased mining waste. The mine tailings being the wastes from rocks and minerals processing, are generally rich in Si, Ca, Al, Mg, and Fe, and also have considerable amounts of heavy metals and metalloids such as Pb, As, Co, Cu, Zn, V, and Cr. When tailings contain sulphide minerals, it may also lead to acid mine drainage. This makes the effective and efficient recycling and reuse of mine waste a major environmental concern. However, the physical, mineralogical and chemical composition of the mine tailings renders it a suitable material for use in civil engineering applications. This paper discusses the use of mine tailings of different origins for different civil engineering applications such as bricks, ceramics, fine aggregates, coarse aggregate and cementitious binders. This approach has a potential to reduce the demand on existing natural resources to face the demands of the exponentially developing infrastructure.

Abstract:
AbstractThe International Vocabulary of Measurement (VIM) and the Guide to Uncertainty in Measurement (GUM) shift the terms and concepts of measurement information quality away from an Error Approach toward a model-based Uncertainty Approach. An analogous shift has taken place in psychometrics with the decreasing use of True Score Theory and increasing attention to probabilistic models for unidimensional measurement. These corresponding shifts emerge from shared roots in cognitive processes common across the sciences and they point toward new opportunities for an art and science of living complex adaptive systems. The psychology of model-based reasoning sets the stage for not just a new consensus on measurement and uncertainty, and not just for a new valuation of the scientific status of psychology and the social sciences, but for an appreciation of how to harness the energy of self-organizing processes in ways that harmonize human relationships.

Full text
Abstract:
This chapter reviews how electricity can be generated from waves and tides. The UK is an excellent example, as the British Isles have rich wave and tidal resources. The technologies for converting wave power into electricity are easily categorized by location type. 1. Shoreline schemes. Shoreline Wave Energy Converters (WECs) are installed permanently on shorelines, from where the electricity is easily transmitted and may even meet local demands. They operate most continuously in locations with a low tidal range. A disadvantage is that less power is available compared to nearshore resources because energy is lost as waves reach the shore. 2. Nearshore schemes. Nearshore WECs are normally floating structures needing seafloor anchoring or inertial reaction points. The advantages over shoreline WECs are that the energy resource is much larger because nearshore WECs can access long-wavelength waves with greater swell, and the tidal range can be much larger. However, the electricity must be transmitted to the shore, thus raising costs. 3. Offshore schemes. Offshore WECs are typically floating structures that usually rely on inertial reaction points. Tidal range effects are insignificant and there is full access to the incident wave energy resource. However, electricity transmission is even more costly. Tidal power technologies fall into two fundamental categories:1. Barrage schemes. In locations with high tidal range a dam is constructed that creates a basin to impound large volumes of water. Water flows in and out of the basin on flood and ebb tides respectively, passing though high efficiency turbines or sluices or both. The power derives from the potential energy difference in water levels either side of the dam. 2. Tidal current turbines. Tidal current turbines (also known as free flow turbines) harness the kinetic energy of water flowing in rivers, estuaries, and oceans. The physical principles are analogous to wind turbines, allowing for the very different density, viscosity, compressibility, and chemistry of water compared to air. Waves are caused by winds, which in the open ocean are often of gale force (speed >14 m/s).

This chapter describes technology that ensures reliable pumping of drainage and sewage water during electromechanical and hydro-mechanical transients from blocks of the hydroelectric power stations and pumping stations. As an alternative source of energy, it is proposed to use the energy of the liquid column of the pressure penstock of the stations, and as an auxiliary, to use jet pumps. Transmission of energy to the suction stream is carried out without direct usage of electrical and mechanical energy. During total shutdown of electric power, reliable evacuation of drainage and seepage water and reduction the influence of electromechanical and hydro-mechanical transients on power equipment and pipelines can be ensured with the use of self-regulating jet pumps over a period of several days; this cannot be accomplished by any other pump. The scientific results of the research are recommended to allow efficient use of water and energy resources and to ensure reliable operation of the power equipment of stations, especially in the events of sudden power outages.

Full text
Abstract:
Sustainable irrigation is sensible application of watering to plants in agriculture, landscapes that aids in meeting current survival and welfare needs. Sustainable irrigation management can help with climate change adaptation, labor, energy savings, and the production of higher-value and yield of crops to achieve zero hunger in water-scarce world. To ensure equal access to water and environmental sustainability, investments in expanded and enhanced irrigation must be matched by improvements in water governance. Sustainable irrigation must be able to cope with water scarcity, and be resilient to other resource scarcities throughout time in context of energy and finance. The themes and SDGs related to clean water, water resources sustainability, sustainable water usage, agricultural and rural development are all intertwined in the concept of “sustainable irrigation for higher yield.” Sustainable irrigation management refers to the capability of using water in optimum quantity and quality on a local, regional, national, and global scale to meet the needs of humans and agro-ecosystems at present and in the future to sustain life, protect humans and biodiversity from natural and human-caused disasters which threaten life to exist. Resultantly higher yields will ensure food security.

Full text
Abstract:
This chapter proposes an alternative system for conventional reverse osmosis (RO) and electrodialysis (ED) desalination plants by incorporating the use of gravitational potential energy (GPE). The proposed system is devised with two subsystems, the RO module followed by the ED module, both simultaneously powered by GPE. This kind of energy is obtained by storing the brackish water to be desalinated. The system’s primary source of energy is wind. Windmills harness the wind energy to pump water to a reservoir located at a certain height (<20 m). The stored water has the GPE that will make a special plunger pump work. The piston of this special plunger pump is designed so that high pressure (about 15 bar) can be achieved in a different way from conventional RO plants. In the alternative system, here proposed, to pump water to the RO membranes, the special pistons go downward due to their own weight and are lifted, through a system of pulleys, with a counterweight filled with water obtained from the reservoir. The technical viability of the alternatives was theoretically proven by deductions based on physics and mathematics and with a special plunger pump prototype that worked successfully.

Gurney epitomizes the dramatic change from nineteenth-century poetry to Modernism, and this change was fundamentally influenced by the example of Hopkins. While Gurney did not mimic Hopkins’s mannerisms or take on his themes, from Hopkins he learned to harness and hold expansive energy within his own eccentric forms. In so doing, Gurney set a pattern for later writers responding to Hopkins.

Full text
Abstract:
Abstract The Heavy Oil Late Life Energy Recovery (HOLLER) project is the application of geothermal technology in steam assisted gravity drainage (SAGD) wells that are near end of life. While conventional geothermal technology is encumbered by the high cost of drilling deep wells to reach formations with the temperatures required for economic power generation, in situ bitumen producers have access to existing SAGD wells within mature reservoirs that are at shallow depths and high temperatures. The thermal energy from just one SAGD well can produce enough electricity to power thousands of homes for a year and major oilsands producers collectively have thousands of such wells. Our goal is to harness this thermal energy using the existing well inventory to create a closed geothermal system using process effluent water (PEW) such as boiler blowdown or tailings pond water as the heat recovery medium. This strategy has the potential to improve SAGD economics through incremental bitumen recovery, the generation of low-carbon base load electricity, and driving down SAGD greenhouse gas (GHG) emissions by recovering some of the spent energy. This strategy also provides an option to dispose process water and/or tailings water to accelerate the reclamation of tailings ponds. Suncor’s In Situ Technology team applied a stage-gated technology development process to progress HOLLER from Technology Readiness Level (TRL) 0—Idea to TRL 7—Field test. We applied the diverge-converge approach to 30 ideas that were distilled into four recommended commercial solutions. Our de-risking activities include numerical reservoir simulation, chemical process simulation, post-SAGD core and water analysis, laboratory studies for compatibility of various PEW sources with reservoir fluids and rock, core flooding, corrosion studies, facility design, economics, risk and uncertainty analysis, patenting, and testing in the field. As a result of the technology development work, we have developed a three-phase strategy to maximize the value of depleted in situ reservoirs: water disposal, energy recovery and permanent closure. This strategy offers synergies between mining and in situ operations, reduction in GHG emissions and environmental liabilities all while generating a net profit for the enterprise. If applied industry-wide, HOLLER technology has the potential of reducing not only the intensity, but also the absolute GHG emissions, while offering unique opportunities for collaboration between the in situ producers and mining operations. HOLLER is unique in its potential to retroactively reduce the GHG intensity of bitumen already recovered by thermal methods. It offers low emissions incremental bitumen production, nearly emissions-free power generation, increased efficiency of existing facilities through the direct use of recovered heat – while reducing mine tailings liabilities. HOLLER enhances the oilsands industry’s sustainability efforts.

Abstract:
Abstract The challenges of improving wiring harness design are safety, ecology, weight and cost. To achieve this, a better prediction of the temperature in the wiring harnesses is necessary. In terms, this involves considering a lot of compact thermal sources with an uncontrolled layout. Up to now, the main methods dedicated to resolution are based on finite elements given that temperature’s evolution according to several thermal sources, Joule effect, without controlled wire layout is complicated to evaluate. This paper deals with an alternative and faster method. An analytic equation : Infinite Line Source (ILS), is used to create a nodal network. This method coming from geothermal heat exchangers relies on a fully-connected node network which is called here full-graph method. It will be shown that, for compact heat sources, this method can be improved with a reduced model. A reduced model is a pruned node network: only the wires corresponding to the adjoining wires are selected. The bundle is a complex system which has a variable environment and an uncontrolled wire layout. The adaptation required by the models requires many assumptions. This case study focuses on a 10 wire configuration with the following assumptions: stationary state, identical wires, axial heat fluxes and neglected heat convection. Comparative studies between the two nodal methods and a Finite Volumes Method (FVM) are also presented and discussed. From a physical point of view, the results are more interesting. Further investigations, depending on the different parameters, should lead us to make more realistic nodal methods.

Abstract:
Abstract In the current study, a novel multi-frequency, vibration-based Energy Harvester (EH) is proposed, numerically verified, and experimentally validated. The structural design of the proposed EH is inspired from an inner-ear, snail-shaped structure. In the past decade, scavenging power from environmental sources of vibration has attracted a lot of researchers to the field of energy harvesting. High demands for cleaner and renewable energy sources, limited sources of electrical energy, high depletion rates of nonrenewable sources of energy, and environmental concerns have urged researchers to investigate new structures called Metamaterial energy harvesters to harness electrical potential. The proposed EH is a metamaterial structure which has a Polyvinylidene Difluoride (PVDF) structure incapsulated in an aluminum frame and follows the physics of a mass-in-mass Phononic crystal structure. The PVDF snail-shaped structure is encapsulated inside a silicone matrix with a specific material property. This EH reacts to the environmental vibrations and the encapsulating silicone entraps the kinetic energy within its structure. The EH unit cell behaves as a negative mass in the vicinity of its resonance frequencies. In this paper, the dynamic behavior of the proposed EH is numerically modeled in COMSOL Multiphysics and, subsequently, validated experimentally using a unit cell fabricated in-house.

Abstract:
Ocean currents contain a remarkable amount of kinetic energy and have potential worldwide capability. Initial tests to harness current power focus on the Straits of Florida where the Florida Current has a total flow capacity of about 30 × 106 m3 s−1. Generation of clean electricity from ocean currents off southeast Florida is based on a power extractor comprised by open-center turbine technology. This innovative turbine provides safe passage for fish and other aquatic species. The water-column array of energy production units (EPUs) will have a 350 km2 footprint, based on a 600 m (10 rotor diameters) downstream separation distance between EPUs with a lateral separation of 400 m. Water depths for the EPU field are in the range of 100 to 500 m. With such a large area of water column and benthic habitat utilized, environmental concerns must be overcome, including routing of transmission lines to shore. Risks and vulnerabilities of the proposed ocean current generated electricity include failure of individual EPUs and damage to sensitive coastal marine environments during installation.

Abstract:
Thurgood Canyon, located on White Sands Missile Range (WSMR), contains an alluvial fan that is bisected by a primary installation road and is in the proximity of sensitive fish habitats. This project was initiated to determine if and how sensitive fish habitats at the base of the fan are impacted by the existing drainage infrastructure and to assess the condition and sustainability of the existing transportation infrastructure. Findings show that the current drainage infrastructure maintains flow energy and sediment carrying capacity further down the fan than would occur in its absence. However, frequent to moderately rare (small to medium) flood events dissipate over 2 km from sensitive habitat, and overland flow and sediment do not reach the base of the fan. Controlled flow diversion is recommended upstream of the road to mitigate infrastructure or habitat impacts during very rare (very large) flood events. A comprehensive operation and management approach is presented to achieve sustainable transportation infrastructure and reduce the likelihood of impacts to the sensitive habitat.

Abstract:
The Sunshine Coast (unless otherwise specified, Sunshine Coast refers to the region which includes both Sunshine Coast and Noosa council areas) is a classic regional hotspot. In many respects, the Sunshine Coast has assets that make it the “Goldilocks” of Queensland hotspots: “the agility of the region and our collaborative nature is facilitated by the fact that we're not too big, not too small - 330,000 people” (Paddenburg, 2019); “We are in that perfect little bubble of just right of about everything” (Erbacher 2019). The Sunshine Coast has one of the fastest-growing economies in Australia. Its population is booming and its local governments are working together to establish world-class communications, transport and health infrastructure, while maintaining the integrity of the region’s much-lauded environment and lifestyle. As a result, the Sunshine Coast Council is regarded as a pioneer on smart city initiatives, while Noosa Shire Council has built a reputation for prioritising sustainable development. The region’s creative economy is growing at a faster rate that of the rest of the economy—in terms of job growth, earnings, incomes and business registrations. These gains, however, are not spread uniformly. Creative Services (that is, the advertising and marketing, architecture and design, and software and digital content sectors) are flourishing, while Cultural Production (music and performing arts, publishing and visual arts) is variable, with visual and performing arts growing while film, television and radio and publishing have low or no growth. The spirit of entrepreneurialism amongst many creatives in the Sunshine Coast was similar to what we witnessed in other hotspots: a spirit of not necessarily relying on institutions, seeking out alternative income sources, and leveraging networks. How public agencies can better harness that energy and entrepreneurialism could be a focus for ongoing strategy. There does seem to be a lower level of arts and culture funding going into the Sunshine Coast from governments than its population base and cultural and creative energy might suggest. Federal and state arts funding programs are under-delivering to the Sunshine Coast.

Abstract:
Research objectives : Identify genetic potential and community structure of soil and rhizosphere microbial community structure as affected by treated wastewater (TWW) irrigation. This objective was achieved through the examination soil and rhizosphere microbial communities of plants irrigated with fresh water (FW) and TWW. Genomic DNA extracted from soil and rhizosphere samples (Minz laboratory) was processed for DNA-based shotgun metagenome sequencing (Green laboratory). High-throughput bioinformatics was performed to compare both taxonomic and functional gene (and pathway) differences between sample types (treatment and location). Identify metabolic pathways induced or repressed by TWW irrigation. To accomplish this objective, shotgun metatranscriptome (RNA-based) sequencing was performed. Expressed genes and pathways were compared to identify significantly differentially expressed features between rhizosphere communities of plants irrigated with FW and TWW. Identify microbial gene functions and pathways affected by TWW irrigation*. To accomplish this objective, we will perform a metaproteome comparison between rhizosphere communities of plants irrigated with FW and TWW and selected soil microbial activities. Integration and evaluation of microbial community function in relation to its structure and genetic potential, and to infer the in situ physiology and function of microbial communities in soil and rhizospere under FW and TWW irrigation regimes. This objective is ongoing due to the need for extensive bioinformatics analysis. As a result of the capabilities of the new PI, we have also been characterizing the transcriptome of the plant roots as affected by the TWW irrigation and comparing the function of the plants to that of the microbiome. *This original objective was not achieved in the course of this study due to technical issues, especially the need to replace the American PIs during the project. However, the fact we were able to analyze more than one plant system as a result of the abilities of the new American PI strengthened the power of the conclusions derived from studies for the 1ˢᵗ and 2ⁿᵈ objectives. Background: As the world population grows, more urban waste is discharged to the environment, and fresh water sources are being polluted. Developing and industrial countries are increasing the use of wastewater and treated wastewater (TWW) for agriculture practice, thus turning the waste product into a valuable resource. Wastewater supplies a year- round reliable source of nutrient-rich water. Despite continuing enhancements in TWW quality, TWW irrigation can still result in unexplained and undesirable effects on crops. In part, these undesirable effects may be attributed to, among other factors, to the effects of TWW on the plant microbiome. Previous studies, including our own, have presented the TWW effect on soil microbial activity and community composition. To the best of our knowledge, however, no comprehensive study yet has been conducted on the microbial population associated BARD Report - Project 4662 Page 2 of 16 BARD Report - Project 4662 Page 3 of 16 with plant roots irrigated with TWW – a critical information gap. In this work, we characterize the effect of TWW irrigation on root-associated microbial community structure and function by using the most innovative tools available in analyzing bacterial community- a combination of microbial marker gene amplicon sequencing, microbial shotunmetagenomics (DNA-based total community and gene content characterization), microbial metatranscriptomics (RNA-based total community and gene content characterization), and plant host transcriptome response. At the core of this research, a mesocosm experiment was conducted to study and characterize the effect of TWW irrigation on tomato and lettuce plants. A focus of this study was on the plant roots, their associated microbial communities, and on the functional activities of plant root-associated microbial communities. We have found that TWW irrigation changes both the soil and root microbial community composition, and that the shift in the plant root microbiome associated with different irrigation was as significant as the changes caused by the plant host or soil type. The change in microbial community structure was accompanied by changes in the microbial community-wide functional potential (i.e., gene content of the entire microbial community, as determined through shotgun metagenome sequencing). The relative abundance of many genes was significantly different in TWW irrigated root microbiome relative to FW-irrigated root microbial communities. For example, the relative abundance of genes encoding for transporters increased in TWW-irrigated roots increased relative to FW-irrigated roots. Similarly, the relative abundance of genes linked to potassium efflux, respiratory systems and nitrogen metabolism were elevated in TWW irrigated roots when compared to FW-irrigated roots. The increased relative abundance of denitrifying genes in TWW systems relative FW systems, suggests that TWW-irrigated roots are more anaerobic compare to FW irrigated root. These gene functional data are consistent with geochemical measurements made from these systems. Specifically, the TWW irrigated soils had higher pH, total organic compound (TOC), sodium, potassium and electric conductivity values in comparison to FW soils. Thus, the root microbiome genetic functional potential can be correlated with pH, TOC and EC values and these factors must take part in the shaping the root microbiome. The expressed functions, as found by the metatranscriptome analysis, revealed many genes that increase in TWW-irrigated plant root microbial population relative to those in the FW-irrigated plants. The most substantial (and significant) were sodium-proton antiporters and Na(+)-translocatingNADH-quinoneoxidoreductase (NQR). The latter protein uses the cell respiratory machinery to harness redox force and convert the energy for efflux of sodium. As the roots and their microbiomes are exposed to the same environmental conditions, it was previously hypothesized that understanding the soil and rhizospheremicrobiome response will shed light on natural processes in these niches. This study demonstrate how newly available tools can better define complex processes and their downstream consequences, such as irrigation with water from different qualities, and to identify primary cues sensed by the plant host irrigated with TWW. From an agricultural perspective, many common practices are complicated processes with many ‘moving parts’, and are hard to characterize and predict. Multiple edaphic and microbial factors are involved, and these can react to many environmental cues. These complex systems are in turn affected by plant growth and exudation, and associated features such as irrigation, fertilization and use of pesticides. However, the combination of shotgun metagenomics, microbial shotgun metatranscriptomics, plant transcriptomics, and physical measurement of soil characteristics provides a mechanism for integrating data from highly complex agricultural systems to eventually provide for plant physiological response prediction and monitoring.

Abstract:
Harlequin ducks (Histrionicus histrionicus) are sea ducks that migrate inland each spring to nest along fast-flowing mountain streams. They are considered one of the most imperiled duck species in North America and occur in two distinct populations on the Atlantic and Pacific coasts. The Pacific coast population includes Washington State, where harlequin ducks breed in the Olympic, Cascade, and Selkirk Mountains. This species is designated as a Management Priority Species by the National Park Service within North Cascades National Park Service Complex (NOCA). This report summarizes harlequin duck surveys conducted during 15 years across a 27-year period (1990 and 2017) on major streams within NOCA, and incidental observations collected from 1968–2021. The primary objectives of these surveys were to 1) document the distribution and abundance of harlequin duck observations within NOCA boundaries, 2) describe productivity (number of broods and brood size), 3) describe breeding chronology of harlequin ducks, and 4) describe habitat characteristics of breeding streams. Sixty-eight stream surveys over 15 years resulted in observations of 623 individual harlequin ducks comprising various demographics, including single adults, pairs, and broods. In addition, we collected 184 incidental observations of harlequin ducks from visitors and staff between 1968–2021. Harlequin ducks were observed on 22 separate second- to sixth-order streams throughout NOCA across the entire 53-year span of data, both incidentally and during harlequin duck surveys by Park staff. Harlequin ducks were detected on 8 of the 13 streams that were actively surveyed. Excluding recounts, 88.7% (n = 330) of individual harlequin duck observations during surveys occurred in the Stehekin River drainage. Between all surveys and incidental observations, 135 unpaired females without broods were sighted across all NOCA waterways. Thirty-nine broods were recorded between NOCA surveys and incidental observations, with a mean brood size of 3.61 (± 1.44 SD; range = 2–10). Breeding pairs were recorded as early as April 5 and were seen on streams until June 15, a period of less than seven weeks (median: May 2), but most pairs were observed within a 3-week span, between April 26 and May 17. Single females (unpaired with a male, with (an)other female(s), or with a brood) were observed on streams between April 26 and August 25 (median: July 3), though most observations were made within a 5-week period between June 12 and July 19. Habitat data collected at adult harlequin duck observation sites indicate that the birds often used stream reaches with features that are characteristic of high-energy running water. While adults occupied all instream habitat types identified, non-braided rapids and riffles were used most frequently, followed by pools and backwaters. Larger instream substrate sizes (cobbles and boulders) were present at most observation sites. Adult harlequin ducks were more often found at locations that lacked visible drifting or lodged woody debris, but drift debris was a slightly more abundant debris type. The presence of gravel bars and at least one loafing site was common. Adult harlequin ducks were more often observed in association with vegetation that offered some cover over the channel, but not where banks were undercut. The average channel width at adult observation sites was 34.0 m (range: 6-80 m; n = 114) and 27.6 m (± 15.7 m; range: 10-60 m; n = 12) at brood observation sites. Compared to adult harlequin duck sites, broods were observed more frequently in low velocity habitat (pools, backwaters), but rarely in rapids. Cobble and boulder substrates were still the most dominant substrate type. Contrary to adult ducks, broods were observed most often observed in meandering stream channels, a morphology indicative of low gradient, low velocity stream reaches. Most broods were observed in stream reaches with gravel bars, loafing sites, and...
