Full textAbstract:
AbstractThomas King’s novel Green Grass, Running Water stands as an indictment of North American colonialism and the continuing injustices facing indigenous peoples; it also offers valuable insights in terms of what constitutes good teaching. With reference to personal experiences of teaching the novel in a large lecture course, this article discusses its author’s efforts at implementing the novel’s implied pedagogical principles, which include a scepticism about granting authority to certain texts over others; a collaborative model of learning; a wariness regarding totalizing narratives and claims of interpretive mastery; and a need to wrestle in class discussion with texts’ unresolved problematics.

O objetivo desta dissertação é o de investigar as disputas pelo poder subjacentes no texto literário do autor cherokee/canadense Thomas King, mais especificamente em seu romance publicado em 1993 intitulado Green Grass, Running Water. Serão destacadas as estratégias performáticas empregadas na desconstrução de representações opressivas de nativo-americanos por discursos ocidentais que compõem um complexo campo de batalha onde vozes em conflito disputam por direitos discursivos nas relações de poder. Se por um lado temos a tradição epistemológica positivista/cartesiana que trabalha há cinco séculos no sentido de exercer controle sobre as representações simbólicas dos nativo-americanos, a fim de que poder executivo e discursivo possa ser exercido sobre eles, por outro lado temos que Thomas King proporciona ao leitor o acesso a uma estrutura cíclica, não hierarquizada da narrativa e do epistêmio nativo-americanos. Esta investigação irá apontar os momentos de conflito entre essas vozes e analisará uma potencial interpretação democrática, de terceira via para esses encontros aparentemente binários. Espera-se ser possível indicar que Green Grass, Running Water propicia um privilegiado campo simbólico para que conflitos culturais e epistemológicos possam ocorrer e ser resolvidos com alguma espécie de resolução positiva em relação ao aspecto frequentemente belicoso dos engajamentos nativos e ocidentais. Para tanto, investigaremos a tradição bíblica e judaico-cristã de hierarquização e como o processo de nomeação de indivíduos e categorias permite que ocorra uma relação de dominação. Discutiremos a estrutura organizacional das comunidades, baseando-nos nas proposições de Zygmunt Bauman, com o intuito de averiguar de que forma o texto literário lida com questões como o pertencimento a grupos que possuem critérios subjetivos de aceitação, permitindo-nos responder se tais critérios permitem uma opção de filiação ou se representam uma demanda coletiva opressiva sobre o indivíduo. Uma análise dos discursos científicos de verdade também será feita, contrastando-os com a construção mítica coletiva das narrativas nativo-americanas como construções alternativas de verdade. Finalmente, teremos um capítulo sobre o poder narrativo da fotografia (mídia presente no romance em diversos momentos), no qual os usos da câmera serão descritos e analisados em seus potenciais de malícia e de narração distorcida.<br>The aim of this paper is to investigate the power struggles underlying the literary text of Canadian/Cherokee author Thomas King in the novel Green Grass, Running Water, published in 1993. We will highlight the performative strategies employed in the deconstruction of oppressive representations of the Native American by Western discursive and mediatic voices. The novel offers an interweaved narrative of Native and Western cultural materials that, together, will compose a complex battlefield of contentious voices that, ultimately, weigh on the balance of power relations to claim discursive rights. On the one hand, we have the epistemological tradition of a Positivist/Cartesian logic that has been working for five centuries to hold sway over the symbolic representations of the Native Americans in order to exert executive and discursive power over them; on the other hand, Thomas King provides the reader a glimpse of the cyclical, non-hierarchized structure of Native narrative and episteme. This investigation will point out the moments of conflict between these two voices and attempt to elaborate on the potential democratic/third-way interpretation of these seemingly binary encounters. We hope to be able to indicate that Green Grass, Running Water provides a privileged symbolic battleground for cultural and epistemological clashes to occur and be settled with some sort of positive resolution to the long-lasting contentious nature of Native and Western engagements. In order to accomplish that, we will delve into the biblical and Judeo-Christian tradition of hierachization and how the process of naming of individuals and categories allows for domination to occur. We will elaborate on the structural organization of communities, based on the propositions of Zygmunt Bauman, in order to assess how the literary text handles issues such as belonging to groups that have subjective criteria for acceptance, aiming at answering whether these criteria allow for an option of membership or if they pose as oppressive collective demands over the individual. An analysis of the scientific discourses of truth will also be provided, contrasting them with the collective mythmaking of Native American narratives as alternative constructors of truths. Finally, we will have a chapter on the narrative power of photography (a medium present in the novel at various moments), in which the uses of the camera are described and analyzed in their guileful and (mis)narrating potentials.

Full textAbstract:
This thesis approaches the question of Canada's postcoloniality through two novels, Nancy Huston's Plainsong and Thomas King's Green Grass, Running Water. Published in 1993, both novels problematize a postcolonial articulation of marginality in Canada, suggesting that it reduces the complexities of otherness to binary divisions of center and margin, colonizer and colonized. While Plainsong imagines the restrictive consequences such a reading may have on the others with which it engages, Green Grass, Running Water pushes past those boundaries to affirm the complex nature of alterity in contemporary Canada. Through King's novel in particular, we are provided a new model for approaching and understanding the nuances of difference in a changing literary and political landscape.

Full textAbstract:
Rewriting previous texts or drawing on past and contemporary sources in order to assert both an identity as well as a discursive position illustrate the ironic process at work in Thomas King's Green Grass, Running Water and Michael Ondaatje's In the Skin of a Lion . The two authors resort to intertextuality as a pre/text to revisit the past that has disregarded, if not written off, other protagonists' perspectives (the Native's and the migrant's) in the making of history. By including references to Melville's Moby-Dick , among many other allusions to literary and filmic works, King presents the Native's self-assertion in the history, of the Americas from the colonizing mission onwards. The focus on Moby-Dick as a doubly significant intertext (because of its biblical and historical content) enables one to examine King's strategic use of irony to simultaneously disrupt the colonial discourse and insert the Native's voice. Sometimes close to Melville's critique on the American society and European colonial attitude, sometimes more eager to re-authorize the Native's standpoint, King achieves a displacement of irony that brings to the fore the Native's text, a text that has remained invisible to history and fiction albeit omnipresent. Ondaatje merges references to The Epic of Gilgamesh into his fiction within an historiographic approach, indebted to John Berger's G ., to articulate in words the building of Toronto from the migrants' position. His epigraphs from the Mesopotamian myth and Berger's G . announce the relationship between building and narrating as a way to make visible the migrant workers' stories and voices. Displacing the discourse from men-in-power to migrant workers, Ondaatje relates irony as inclusive of both the said and the unsaid to the migrants' invisibility in the Canadian society.

Full textAbstract:
La présente recherche a pour but de procéder à une étude comparative du processus régénératif au cœur de deux romans phares de la fiction autochtone contemporaine, soit Ceremony de Leslie Marmon Silko et Green Grass, Running Water de Thomas King. Trois volets principaux sont examinés : le rôle de la nature en tant que référent culturel dans le processus de régénération des personnages principaux de chaque roman, l’évolution de la quête identitaire dans un environnement post-contact, ainsi que les répercussions de la réactualisation de l’identité de chaque protagoniste sur la communauté à laquelle il appartient. Cette comparaison entre les procédés employés par Silko et King permettront, en un premier temps, d’identifier des éléments de continuité entre les deux auteurs. Ces similarités incluent la centralité de la nature dans la reconnexion des protagonistes avec leur culture et leur identité ainsi que l’emphase sur la nécessité d’une identité hybride dans un environnement post-contact. De plus, la comparaison entre ces deux auteurs issus de deux contextes socio-historiques distincts permet d’isoler certains éléments du contexte propre à chaque roman afin de déterminer le rôle de la réalité autochtone sur la fiction produite à chaque époque. De façon plus spécifique, il sera entre autres question de l’influence de la montée du mouvement environnementaliste euro-américain sur la valeur symbolique du retour à la nature, ainsi que de l’importance grandissante de la classe moyenne autochtone éduquée et de la façon dont ce nouveau phénomène est exprimé dans l’œuvre de King.<br>This thesis compares the regenerative processes at the heart of two milestone novels of contemporary Native American literature, Leslie Marmon Silko’s Ceremony and Thomas King’s Green Grass, Running Water. My comparative study will be divided into three main sections: the role of nature as a cultural referent in the main characters’ regenerative processes in each novel, the evolution of the identity quest in a post-contact environment, and finally, the repercussions of the protagonists’ re-actualization of identity on the rest of their community. Through the comparative study of the processes employed by Silko and King with respect to one’s relationship to nature, cultural identity and social relations, I will be able to identify several similarities shared by the two novels, which demonstrate that they belong to the same Native artistic continuum. These resemblances include the central role of nature in reconnecting the protagonists to their identity, as well as a predominant emphasis on the emergence of a hybridized identity in a post-contact environment. Moreover, the comparison of two novels emerging from two different eras of Native American Literature –that of the 1970s and of the 1990s- will allow me to isolate the influence of the cultural context to which each particular work belongs. In doing so, it becomes possible to determine the influence of some transformations in Native lifestyle on the fiction produced at a given time. More specifically, the modifications I chose to focus on include the rise of Euro-American environmentalism on the symbolic value of returning to nature for Natives as well as the increasing presence of middle-class, educated Natives and their representation, mostly present in King’s fiction.

Full textAbstract:
June, when the snows come hurrying from the hills and the bridges often go, in the words of Emily Dickinson. In the beaver meadow, the snows are indeed hurrying from the surrounding hills. Every one of the 32 square miles of terrain upslope from the beaver meadow received many inches of snow over the course of the winter. Some of the snow sublimated back into the atmosphere. Some melted and infiltrated into the soil and fractured bedrock, recharging the groundwater that moves slowly downslope and into the meadow. A lot of the snow sat on the slopes, compacted by the weight of overlying snow into a dense, water-rich mass that now melts rapidly and hurries down to the valley bottoms. North St. Vrain Creek overflows into the beaver meadow, the water spilling over the banks and into the willow thickets in a rush. I can hear the roar of water in the main channel well before I can see it through the partially emerged leaves of the willows. Overhead is the cloudless sky of a summer morning. A bit of snow lingers at the top of the moraines. Grass nearly to my knees hides the treacherous footing of this quivering world that is terra non-firma. I am surrounded by the new growth of early summer, yet the rich scents of decay rise every time I sink into the muck. I walk with care, staggering occasionally, in this patchy, complex world that the beavers have created. I abruptly sink to mid-thigh in a muck-bottomed hole, releasing the scent of rotten eggs, but less than a yard away a small pocket of upland plants is establishing a roothold in a drier patch. A seedling spruce rises above ground junipers shedding yellow pollen dust and the meticulously sorted, tiny pebbles of a harvester ant mound. I extract my leg with difficulty and continue walking. As I walk around the margin of another small pond, the water shakes. Sometimes the bottom is firm in these little ponds, sometimes it’s mucky—I can’t tell simply by looking through the water.

It required some rudeness to disturb with our boat the mirror-like surface of the water, in which every twig and blade of grass was so faithfully reflected; too faithfully indeed for art to imitate, for only Nature may exaggerate herself. The shallowest still water is unfathomable. Wherever the trees and skies are reflected, there is more than Atlantic depth, and no danger of fancy running aground. We notice that it required a separate intention of the eye, a more free and abstracted vision, to see the reflected trees and the sky, than to see the river bottom merely; and so are there manifold visions in the direction of every object, and even the most opaque reflect the heavens from their surface. Some men have their eyes naturally intended to the one and some to the other object....

Full textAbstract:
Enzymes are biocatalysts constructed of a folded chain of amino acids. They may be used under mild conditions for specific and selective reactions. While many enzymes have been found to be catalytically active in both aqueous and organic solutions, it was not until quite recently that enzymes were used to catalyze reactions in carbon dioxide when Randolph et al. (1985) performed the enzyme-catalyzed hydrolysis of disodium p-nitrophenol using alkaline phosphatase and Hammond et al. (1985) used polyphenol oxidase to catalyze the oxidation of p-cresol and p-chlorophenol. Since that time, more than 80 papers have been published concerning reactions in this medium. Enzymes can be 10–15 times more active in carbon dioxide than in organic solvents (Mori and Okahata, 1998). Reactions include hydrolysis, esterification, transesterification, and oxidation. Reactor configurations for these reactions were batch, semibatch, and continuous. There are many factors that influence the outcome of enzymatic reactions in carbon dioxide. These include enzyme activity, enzyme stability, temperature, pH, pressure, diffusional limitations of a two-phase heterogeneous mixture, solubility of enzyme and/or substrates, water content of the reaction system, and flow rate of carbon dioxide (continuous and semibatch reactions). It is important to understand the aspects that control and limit biocatalysis in carbon dioxide if one wants to improve upon the process. This chapter serves as a brief introduction to enzyme chemistry in carbon dioxide. The advantages and disadvantages of running reactions in this medium, as well as the factors that influence reactions, are all presented. Many of the reactions studied in this area are summarized in a manner that is easy to read and referenced in Table 6.1. Carbon dioxide is cited as a good choice of solvents for a number of reasons. Some of the advantages of running reactions in carbon dioxide instead of the more traditional organic solvents include the low viscosity of the solvent, the convenient recovery of the products and non-reacted components, abundant availability, low cost, no solvent contamination of products, full miscibility with other gases, non-existent toxicity, low surface tension, non-flammability, and recyclability. The low mass-transfer limitations are an advantage because of the large diffusivity of reactants.

By late April, the snow is gone from the beaver meadow. The promises of March are starting to be fulfilled: insects are on the wing, some of the willows have furry catkins along their branches, and fish jump from the quiet waters of the beaver ponds. I can no longer easily get around the beaver meadows on foot unless I wear chest waders. The sound of the beaver meadow in March was primarily wind. By April, the sound is primarily moving water. The water gurgles, shushes, and whispers. In another month it will roar with the melting snows. Another three miles up the creek valley and 1,500 feet higher, one of my long-term study sites still lies under 6 feet of snow, but in the meadow I see only one patch of tenacious snow-ice in the deep shade beneath a spruce along the northern edge of the meadow. I know that snow will still fall here during late spring storms, but it will melt quickly. March felt on the cusp, as if it could as easily tip toward winter or spring. Late April is definitely spring headed toward summer. The beaver meadow remains a riverscape more brown and tan than green. The willows are still leafless, although some of the branch tips are turning pale yellow-green and others seem to be taking on a more vivid orange hue. I can see the leaf buds starting to swell. The grass has just begun to grow in dark green tips steadily forcing their way through the thick mat of last year’s dead stems. Clusters of new leaves on low-growing wintergreen are the only other sign of green outside of the channels. Some of the smaller side channels are thick with emerald green algae undulating slowly in the current. A stonefly lands on my hand. Its slender, dark gray body seems surprisingly delicate for a creature that has hatched into the vagaries of April air, with its potential for blasting winds and sudden snow squalls.

By mid-July, abundant water continues to move in all directions within the beaver meadow. Water flows noisily down the main channel, creating deep pools where it mixes with water entering from secondary channels. Deeper waters well up from beneath overhung banks and the willow stems along the banks remain partly submerged. Pieces of driftwood collect where the channel bends, floating in perpetual circles atop the shadowed water. The water is clear of suspended sediment but stained slightly brown. Flow is noticeably lower in the secondary channels, where algae and bacteria stain the cobbles reddish-brown. Shallow water runs down a beaver trail toward the main channel, and I can easily imagine the trail eroding into a small canal over a period of years. The fern-like stems of rust red that grew beneath the pond waters earlier in the season have now emerged and bloomed, revealing a row of pink flowers of elephant’s head. Diminutive white twinflowers bloom near the conifers at the edge of the meadow. Stalks of pink and white Pyrola flowers rise above their ground-hugging leaves, which have been green since April. Mountain bluebells form clusters of indigo among the green hues of the grasses and sedges. Broad white blossoms of cow parsnip create a canopy above the other herbaceous plants. Aptly named shooting stars resemble tiny bursts of yellow and white trailing spiraling pink petals as they lean over the ground. The songbirds are less vocal than in June now that they are busy tending to nestlings weak at flying, but I can still hear the notes of chickadees, sparrows, and warblers, underlain by the distant croaks of ravens. Hummingbirds continue their mating displays, diving toward the ground as though intent on suicide, only to pull up at the last moment. The red blazes on their throats flash like fragments of momentary flame amidst the thick greenery. Mosquitoes are more noticeable now, despite the damselflies and dragonflies busily hunting back and forth across the openings among the willows. Beds of matted grass lie dispersed across the meadow.

Full textAbstract:
In this chapter we deal with vegetation growing in the field. This introduces new and challenging questions of scale and heterogeneity, in time and space, of the environment in which plants grow. It builds on the concepts and methods explained in earlier chapters, especially the movement of water and solutes (chapters 2, 3 and 4) and the distribution of roots (chapter 9) in field soils. In some cases, it requires changes and simplifications in the methods that we have used earlier. The problems of dealing with water and nutrient movement and uptake at the field scale are discussed first. The modelling approach that we developed in the earlier chapters of this book, up to the end of chapter 10, logically resumes at section 11.3. This covers both uptake models and the more complex combined crop growth and uptake models that simulate the main interactions with the environment. This chapter considers increasingly complex systems: first, uniform monocultures, including models of a ‘green leaf crop’, a root crop, a cereal, and a tree crop. At this level, the presence of weeds or groundcover is deliberately ignored. Interspecies competition is included later, with vegetation composed of more or less regularly spaced plants of more than one species. This occurs in many agricultural systems, such as mixtures of forage species and agroforestry systems. The competition processes become even more complicated where there is no spatial symmetry, and models of crop/weed mixtures, grass/legume mixtures, and planted woodlands are used as examples. Progress with crops has been more rapid because of their more regular structure, so we deal mainly with these, but we believe that similar ideas will be applied to natural vegetation also, and this is discussed in section 11.5. Most of these models have a water submodel, or, if not, one could be added. As the physical basis is normally rather similar for all water models, one model for water uptake is explained in some detail (section 11.1.2), but elsewhere water uptake is dealt with very briefly. For each model, the preferred order of discussion is water; growth, including economic yield; nitrogen; potassium; phosphorus; and other nutrients, unless the logic of the subject demands a different order.

Full textAbstract:
When we drive by a modern farm, we still expect to see green plants sprouting from the earth, bearing the promise of food or cooking oil or a cotton shirt. Pulling up one of those plants, we are still prepared to find dirt clinging to its roots. Even in this age of high-tech euphoria, agriculture remains essentially a matter of plants growing in the soil. But another element besides soil has always been a part of the farmer’s life-water. Farming is not only growing crops on a piece of land, it is also growing crops in water. I don’t mean a hydroponics lab. I mean that the farmer and his plants inescapably are participants in the natural cycle of water on this planet. Water is a more volatile, uncertain element than soil in the agricultural equation. Soil naturally stays there on the farm, unless poor management intervenes, whereas water is by nature forever on the move, falling from the clouds, soaking down to roots, running off in streams to the sea. We must farm rivers and the flow of water as well as fields and pastures if we are to continue to thrive. But it has never been easy to extract a living from something so mobile and elusive, so relentless and yet so vulnerable as water. If there is to be a long-term, sustainable agriculture in the United States or elsewhere, farmers must think and act in accord with the flow of water over, under, through, and beyond their farms. Preserving the fertility of the soil resource is critical to sustaining it, of course, but not more so than maintaining the quality of water. In many ways, the two ideals are one. And their failure is one, as when rain erodes the topsoil and creeks and rivers suffer. But there are differences between those two resources, differences we must understand and respect. Unlike soil, water cannot be “built.” It can be lost to the farmer, or it can be diverted, polluted, misused, or over-appropriated, but it can never be deepened or enhanced as soil can be.

Full textAbstract:
The first week of September mostly feels like summer. The air on the dry terrace bordering the beaver meadow is richly scented with pine. Purple aster, blue harebells, and tall, yellow black-eyed Susan still bloom. Fungi are more abundant on the forest floor, and the tiny, purplish berries of kinnikinnick are sweet to the taste. The air is warm in the sunshine, but strong winds hurry rain showers through at intervals. Patches of last year’s snow linger on the surrounding peaks, even as the first light snows have already fallen in the high country. Down in the beaver meadow, the leaves of aspen, willow, birch, and alder are starting to assume their autumn colors. Here and there a small patch of yellow or orange appears among the green. Blades of grass have a pale orange tint and the strawberry leaves have gone scarlet, even as white asters, purple thistles, and a few other flowers continue to bloom. The creek is noticeably lower, its cobble bed slick with rust-brown algae. Exposed cobble and sandbars have grown wider as the water has shrunk back from the edge of the willows, and the main channel is easy to cross on foot. The clear water is chillingly cold in both the main channel and the side channels. The smaller side channels no longer flow, and a drape of mud mixed with bits of plants covers the cobbles. Wood deposited a year ago has weathered to pale gray. The older, marginal beaver ponds have shrunk noticeably, and the water is lower in the main ponds, where tall sedges now lie bent on the top of the declining water surface. The beavers remain active: following fresh moose tracks, I come on a newly built beaver dam on a small side channel. By the third week of September, autumn has clearly arrived in the mountains. The air remains quite warm during the day, but nights of frost are swiftly bringing out the autumn colors. Whole stands of willows and aspen now glow golden or pumpkin-orange.

Green water effect is a highly nonlinear free surface problem. It can cause severe damage on floating marine structures. Therefore, it is of great importance to be able to predict the green water occurrence on the freely-moving floating marine structures and the associated dynamic loads acting on them. In the proposed paper, a solution scheme for solving the green water problem in the numerical wave tank with commercial CFD software FLUENT will be presented. This solution scheme consists of the decompositions of the computational domain, and an automatic updating method for the motion of the moving object. The numerical wave tank is set up by using a plunge-type wave-maker to generate waves and by adding source terms in the dissipation zone to eliminate the reflected waves. The computational domain is divided into dynamic zones, stationary zones, dense rigid zone that is useful in capturing the green water details, and the fine mesh zone near the free surface. The mesh in the vicinity of the moving object (dense rigid zone) is refined to better model the green water problem. The motion response of the object is obtained based upon the solution of the general equations of rigid body motion (6-DOF) and the hydrodynamic forces acting on the object. In order to compare with the existing experimental data, a 2D object is used in the numerical study. The motion of the object is restrained from surge, which means only heave and pitch motions are allowed. The details of the green water occurrences including water running up onto the deck, water propagating on the deck, water impacting the vertical wall, water running up along the vertical wall, wave breaking and water spray have been modeled successfully. The quantitative analysis on the impact load on deck and the upper structure has also been carried out. The comparison of the numerical results and experimental measurements shows that the current numerical solution scheme is robust and reliable in modeling green water problem.

The process of construction can be defined as an extensive system that builds the accommodations for people to settle in, as well as the construction of facilities that keep up the development process. Some of the main steps that the process would cover are the extracting and benefiting raw materials, manufacture of building materials and elements, the construction of the project run from viability to inspection, and the regulation and running process of the sites. The most profound challenges that many cities n Iraq share illustrate the consequences of urban growth. Thus, this study seeks to examine the aspects of sustainability that influence the decisions for the process of building up green building projects. A total number of fourty respondents have been requested to evaluate nine elements of building sustainability: life cycle evaluations, energy conservation and renewable energies, water conservation, environmentally friendly construction supplies and standards, depletion of waste materials, alleviation of toxic materials, adequate indoor ventilation, smart innovation, and sustainability in the development of the building process and ecologically friendly construction projects. The findings show that the respondents preferred the use of elements that could give better sustainability in the process of construction building to ensure a healthier and better quality of life. This preference is established from the concept of green building technology. The most chosen aspect for this concept is the efficiency of energy and the use of renewable energy, followed by the alleviation of toxic materials, adequate indoor ventilation, and water conservation.

The so-called numerical wave tank is to use a mathematical model to simulate the process of making waves and interaction between waves and structures. Shipping water occurs when the wave height exceeds the deck level of a floating vessel. A large amount of seawater flows down onto the deck. It damages deck equipment and causes even submergence. The water on deck is called “Green Water”, and it is dangerous for ships. It is of great significance to analyze and simulate wave and green water phenomenon. This paper developed a three-dimensional numerical wave tank and presented VOF method to deal with the movement with free surface, and then simulated process of wave generation numerically. A two-dimensional numerical simulation of the green water phenomenon of a hull placed in regular wave was performed. The process of wave running up and wave deforming were obtained. The results show that the present numerical scheme and methods can be used to simulate process of wave generation and phenomenon of green water on deck, and to predict and analyze the impact forces between waves and structures due to green water.

Green or living walls are active bio-filters developed to enhance air quality. Often, these walls form the base from which plants are grown; and the plant-wall system helps to remove both gaseous and particulate air pollutants. A green wall can be found indoors as well as outdoors, and could be assembled from modules in an arrangement similar to tiling. The module is a rectangular plastic box (dimensions about 500 mm × 500 mm × 130 mm) that holds a permeable bag containing a plant-growing medium (replacement for soil). The front face of the module has multiple openings for plants to protrude out from the bag inside. Plant roots are imbedded in the medium. A fan positioned at a central opening on the module’s back face drives air through the medium-plant-roots mix and then onward through the plants′ canopy; and these would help remove both gaseous and particulate pollutants from the air. Volatile Organic compounds (VOCs) and particulate matters PMs are both reduced by passing through the plant-growing medium, thus reducing the percentage of air flow that passes through the open top face of the module is essential to maximize the capacity of bio-filtration. Drip-irrigation water is dispensed from a tube running along the open top-face of the module. The module has also a small drainage hole on its bottom face. Pressure drop across the module as well as air-flow rate through it have been obtained in a previous work [1], air-flow distribution through the module and the effect of introducing a cover to the module’s open top face are investigated in this work to improve the design of the module and achieve more appropriate flow rate and flow distribution. The top cover essentially includes small holes of 10 mm diameter to allow the necessary irrigation. The measurements help to determine the pattern of flow resistances which in turn will be used in a future CFD (Computational Fluid Dynamics) analysis.

In this paper, design and economic analysis for applying a novel type of heat pipe into cold energy storage systems have been proposed and discussed. The heat pipe cold energy storage systems can be designed into several types that are ice storage, cold water storage and pre-cool heat exchanger. Those systems can be used for co-operating with conventional chiller system for cooling data centers. The heat load used for discussing in this paper is 8800 kW which represents a large scale data center. The methodology addressed in this paper can be also converted into the middle and small sizes of the data centers. This type of storage system will help to downsize the chiller and decrease its running time that would be able to save significant electricity cost and decrease green house gas emissions from the electricity generation. The proposed systems can be easily connected into the existing conventional systems without major design changes. The analysis in this paper is using Air Freezing Index AFI &gt;= 400 °C-days/year for sizing the heat pipe modules. For the locations where AFI has different value the storage size will be varied accordingly. The paper also addressed a result that an optimum size of cold energy storage system that should be designed at a level to handle 60% of total yearly heat load of a data center.

Since the Industrial Revolution one of the oldest and “greenest” bio-fuel energy sources has been the byproduct of sewage and landfill. These biogases also known as Land Fill Gas or Digester Gas can be used as a fuel in an internal combustion engine, the clear choice for their efficiency in heat recovery and utility as a prime mover. The problem with bio-fuels is their unpredictable and varying fuel heating values which creates a challenge for maintaining air fuel ratio (AFR). If AFR is not controlled this can lead to engine instability and an increase in NOx, CO and THC emissions. With today’s ever increasing scrutiny of combustion pollutants this could spell the end of these types of fuels in combustion engines. AETC has embraced this challenge to provide a system that addresses the seasonal fuel gas quality, Low Heating Value (LHV) fluctuation to operate engines at best achievable emissions. This case study focuses on two Caterpillar 3516 Generator Engines rated 1000VA, at 1200 rpm, lean burn gas and turbocharged, running on renewable energy source supplementing power to a waste water treatment facility in California. The engines operate on wide range of fuel mixture including landfill, digester gas and air blended natural gas over a heating value range from 350–650 BTU. The fuel gas LHV constantly varies depending on fuel availability controlled by pressure switches within the individual fuel headers. Determining fuel heating values by using a gas calorimeter is not a viable option due to its high cost and poor reliability when operating in the environment of unfiltered Digester and landfill gas. AETC installed their Advanced Monitoring System (AMS) to utilize the engine as a calorimeter and to determine the fuels LHV. As part of the AMS functionality, the system acquired all the existing AFRC parameters such as kilo-Watt, RPM, Fuel Flow, Air Manifold Pressure and Temperature to determine the combustion performance. This simple approach offers surprisingly good performance while tying together basic thermodynamics, combustion performance and emissions. The system can also be used to parametrically determine engine emissions, based on the calculated combustion pressure without installing pressure sensors. The AMS monitors and determines emissions based on Trapped Equivalence Ratio, Effective Bulk Temperature or Pressure Ratio on single or multiple fuels providing a green/red light as an indicator of in/out of compliance accurately meeting today’s most stringent regulatory conditions.
