Computational and experimental simulation of wind impacts on a lattice structure

This work involves the study of wind impact on a lattice structure. Permeable lattice structures are widely used in construction all over the world (oil derricks and power line pylons, etc.); at the same time, the aerodynamic forces acting on such structures may make a decisive contribution to their stability. There are several methods of lattice structure computation for wind impacts: a computation according to the existing normative documents and experimental and numerical simulation. Each of the above methods has its own merits, demerits, and difficulties. Thus, the normative documents do not allow to compute complex space-frame structures. In this work a computational and experimental approach is utilized. An experimental study is conducted in a wind tunnel to determine the integral aerodynamic characteristics, while the local aerodynamic characteristics are determined based on the results of numerical simulation in a CFD complex. A valid numerical model is used the parameters of which ensure the reconciliation of the obtained results with the experiment data. At the next stage a vortex resonance excitation of the lattice structure is studied. This methodology makes it possible both to determine the values of aerodynamic coefficients necessary for computing the wind load on the structure as a whole and evaluate the vortex resonance excitation probability.

Pop Goes the Weasel: How Greed and a Good Barbecue Hoodwinked a Small Town

On October 4, 1921, Sure Pop Oil Company held a barbecue to celebrate the newly built oil derrick and attract new investors in Eureka Springs, Arkansas. The Eureka Springs Historical Museum has photos from the celebration. Local lore suggests that the oil company owners were "confidence men" who were out to "fleece" the citizens of Eureka Springs. A clearer picture of the Sure Pop Oil Company and its president can be attained by studying newspaper articles and census records. Start with the zeal after the discovery of oil in El Dorado, Arkansas, coupled with the lack of federal and state legislation protecting investors, and throw in a dash of human greed, and you have a recipe for disaster.

Ethical Criticism and There Will Be Blood: Autonomism, Moralism, and Immoralist Perspectives

The article explores the role played by moral categories in the assessment of an artwork’s overall aesthetic value. By means of close analysis of Paul Thomas There Will Be Blood, the work maintains an immoralist approach, where an artwork’s unethical attitude may yield cognitive gain to its receiver—or perhaps unsettle their moral compass in an unusual, pleasant way. There Will Be Blood is considered a cinematic masterwork; yet, the viewing experience is complicated by the film’s greedy and self-obsessed protagonist, Daniel Plainview (Daniel Day-Lewis). The article scrutinizes the film’s most notable sequence—the explosion of the oil derrick—to formulate an aesthetic evaluation that manages to assess, simultaneously, formal and moral aspects.

Time-Dependent Reliability Analysis of Oil Derrick Structures in Mechanism Failure Mode

Most research studies on the reliability of oil derrick structures have focused on static reliability analysis. Strength degradation with time of oil derrick structures and mechanism failure should also be considered in reliability analysis. In order to address this issue, we propose a new time-dependent reliability analysis method for oil derrick structures in mechanism failure mode and apply it to a tower derrick structure. We used the Monte Carlo finite element method to compute the static failure probability of each derrick component, and steps were employed to determine the main failure mechanisms. The time-dependent failure probabilities of each derrick component in the main failure mechanisms were calculated by the total probability theorem. The time-dependent reliability of a derrick structure system was obtained by considering the system as a series of parallel subsystems. A tower derrick example was used to demonstrate the accuracy and applicability of the proposed method. The results revealed that the proposed method is accurate and reliable.

Sweet-Gas

Sweet-Gas Carolyn Orosz (bio) Sweet-Gas We have been sleeping in the Cottonwood Creek oil fields,or half-sleeping, eating cross-legged around a pit of off-brand mountain dew remains, all the stars falling out of the sky like sawdust,like confetti, like all fears are fragmentsin the end. And this is the end. Here now, isn't it? The ground in the desert braided exactly like that erosion boardmy brother made for the sixth-grade science fair. Driving through the moonscape—limestone barnacles at the roadside, hay fires visible at the horizon, huge culverts in the drainages & the drainages dry.The purple stain of juniper, all the cheatgrass cured. At 8 am the light smolders so all around half the land is hidden.Everything is either invisible or illuminated— the oil derricks calling out to us with their signal fires,all of the horses tossing their heads, sunning their glowing necks. Herons, great/grey-blue grazing alongside the cattle.Each of us, naked, goes on unaware of our own nakedness. There's nothing here.There's nothing anywhere, that's the thing.

The apocryphal eagle with a snake initsbeakstandingatopanopalislikely the most recognizable symbol of Mexico. It is the central figure of the bandera nacional and serves as a statement of ethnic and cultural hybridity linked to deep (pre)historical roots. However, considering the developmentofMexicosincetheearlytwentiethcen tury —throughtheRevolution,the“Mexican Miracle,” the long PRI hegemony, the neoliberal turn, and now into the post-neoliberal era it may be entering—perhaps a gushing oil derrick would be a more fitting, if less aesthetically pleasing, symbol at the center of the flag. Oil has been central to Mexico’s revenues and the economic and social development it has paid for have created a general sense of national pride and self-determination around oil. Today, Mexico is the twelfth largest producer in the world of oil and eighteenth globally in natural gas. Despite declining production from the Cantarell and Ku-Maloob-Zaap superfields, oil and gas development remains a linchpin of Mexico’s financial bottom line and thus its political stability. The edited volume El petróleo en Mexico y sus impactos sobre el territorio takes this as a given fact and goes a step further, through geographical explorations of how oil has made itself spatially manifest, via the concepts of territory and landscape. The editors, Martin M. Checa-Artasu and Regina Hernández Franyuti, note from the outsetthatthisbookisthesummaryresultof a 2015 symposium of presentations concerning the clearly stated title of the book. The editorsmakethisbookmoreconceptuallyfocusedbyleadingitssixoriginalcontributions with well-written and deeply-researched introductoryandbibliographicchapters .What follows are an assortment of chapters that range from the theoretical to the methodological and empirical investigating the spatialities of hydrocarbons in Mexico. In the opening bibliographic chapter, Martin Checa goes through an impressively expansive epistemology of hydrocarbon extraction in Mexico. Aiming this work at scholars of hydrocarbon extraction in Mexico , Checa begins by framing the epistemology within the political-economic structures that produced it. He then organizes seminal works on the subject by theme and chronology . Later in the chapter, Checa narrows this broad literature to works that bear a “vinculo territorial,” rolling them out through their 6 Journal of Latin American Geography evolutionary stages or turns, geographic/ regional focus, and thematic categories, all which serve to create the broader context into which the following six chapters fit. The heart of the book begins with a historical examination on the potential ecological consequences of the 2013–2014 Energy Reforms in Mexico. Author Myrna Santiago, a preeminent environmental historian of oil, begins by providing a legal history of Mexican constitutional law related to hydrocarbons ,fromtheearlytwentiethcenturytothe 1938 expropriation and Pemex years, to modifications of Article 27 and the recent energy reforms. In a compelling narrative, Santiago showshowtheselegalchangestohow,andby whom, hydrocarbons can be extracted have affected people and environments in Mexico . The violent dispossession of campesinos and indigenous people amid ecological ruin that are associated with twentieth-century hydrocarbon development serve as a warning for the post-reform hydrocarbon regime in Mexico. The next chapter, again by Checa, positions itself at the thematic core of the volume . In it, he explores the concept of territoriality of hydrocarbon development in Mexico by showing how the interrelation of geology, infrastructure, and professional practice have produced the fundamental territorial unit of the Mexican energy sector , the campo or “field.” This in-depth and well-researched chapter illustrates how the hydrocarbon campo is defined as a legal entity , as a resource, and a container for the environmental and the demographic. In essence, Checa outlines the social and discursive production of space embodied in the Mexican hydrocarboncampo.Checa’stakehereisthat the campo is but a mere spatial construction that fundamentally hides a richer, more “real” understanding of Mexican hydrocarbon territoriality .Hethenproposesthattheconcept...

Drilling Rig Hoisting Platform Security Monitoring System Design and Application

Drilling rig hoisting platform security monitoring system has played a very important role in oil exploration. And drilling parameters and working condition of workers are particularly important, because these parameters indicate that whether the drilling work is safe and effective directly. A security monitoring system is established to provide the real-time parameters for drilling safety is the purpose of this study. The monitoring system includes a top drive, a traveling block hook, an oil derrick and a driller room, and the controller of the system is programmable logic controller PLC. The procedure of the system is written by the RSLogix5000 software, the PC configuration is used force control monitor configuration software. According to the system, top drive, driller room and environment wind speed parameters in real-time are collected and displayed in the configuration of upper computer, the collected parameters can be used to determine the working conditions of the top drive and to send timely warnings for inspection maintenance to avoid drilling safety accidents. Work fatigue remind of driller and regularly remind of derrick check can be as much as possible to reduce safety accidents. And automatic operation of traveling block hook reached the default point faster and more smoothly than manual operation given the other uncontrollable factors in manual operation. The application of the system is successfully working in the drilling work site.

Carbon nation: fossil fuels in the making of American culture

Fossil fuels power our cars, our food supply, our climate-controlled homes, our work, and our play. That much we know. What we understand less, and what this book makes clear, is how fossil fuels also condition Americans' sensory lives, erotic experiences, and aesthetics; how they structure what we assume to be normal and healthy; and how they prop up a distinctly modern bargain with nature that allows populations and economies to grow wildly beyond the previously understood limits of the organic economy. Carbon Nation ranges across film and literary studies, journalism, politics, art history, and ecology, to chart the course by which prehistoric carbon calories influenced--in both conscious and unconscious ways--the modern American economy and body. This includes our ways of being, sensing, and knowing as different classes, races, sexes, and conditions learned to embrace, absorb, and navigate the material manifestations, cultural potentialities, and myriad costs of fossil fuels. Combining historical ecology with cultural criticism, this book reveals the profound depths of our dependencies on carbon and the long repressed cultural history of our evasion and neglect of those dependencies. The ecological roots of modern America are introduced in the first half of the book with the revolution in material growth generated by the move from limited organic soil resources to subsoil energies. In the works of Eugene O'Neill, Upton Sinclair, Sherwood Anderson, and Stephen Crane, the author exposes how coal as a cultural object is used to suppress our dependencies, buried beneath modernist narratives of progress, consumption, and unbridled growth. In films like Charlie Chaplin's Modern Times and George Stevens's Giant we discover cinematic expressions of our deep-seated anxieties about living in a dizzying new world wrought by fossil fuels. Any discussion of fossil fuels must go beyond energy policy and technology. As Bob Johnson reminds us, in provocative and powerful ways, what we take to be natural in the modern world is, in fact, historical, and our history and our culture have risen from this relatively recent embrace of the coal mine, the stoke hole, and the oil derrick.

Damage Identification Method Based on LMD Sample Entropy and SVM for Oil Derrick

To identify damaged position of oil derrick, this paper presents a damage identification method for oil derrick using LMD and sample entropy to extract eigenvector and SVM to identify classes. Hammering vibration response signal of damaged derrick is decomposed into several PF components. The sample entropy of PF components is calculated and used as eigenvectors. SVM classifier is constructed based on eigenvectors of different damage location, and this method can identify damage position accurately. This method is verified by comparison with recognition result of LMD and information entropy.

INDUCED VOLTAGE ON THE OVERHEAD LINE AT OIL EXPLOITING PORT UNDER LIGHTNING STRIKE

In this paper, a computational model is established for the flnite-difierence time-domain analyses of induced voltage on the overhead line at oil exploiting port under lightning strike. The MTLL approximate formulation is used to simulate the lightning strike, and convolutional perfectly matched layers are used to truncate the computational domain. A two-step method is established to calculate the coupling to the overhead lines to reduce the huge computational domain of the conventional 3-D FDTD simulation. Parallel implementation is introduced for the second-step calculation to overcome the memory storage limit of a single computer. With this model, the electromagnetic fleld at the adjacent areas and the induced voltage on the overhead line are studied when lightning strikes an oil derrick. It is demonstrated that the electromagnetic fleld decreases as the distance from the oil derrick increases, but the vertical fleld decrease much slower than the horizontal fleld. It is also shown that the transversely located overhead line will introduce lower voltage than the radially located line. As the length of the overhead line increases, the induced voltage increases and the low-frequency induction is strengthened. The overhead line should be set as low as possible to reduce the induced voltage.

Field amputation: Response planning and legal considerations inspired by three separate amputations

Surgical procedures in the field are occasionally required as life-saving measures. Few centers have a planned infrastructure for field physician support. Focused efforts are needed to create teams that can meet such needs. Additionally, certain legal issues surrounding these efforts should be considered. Three cases of field dismemberment inspired this call for preparation. In one case, an earthquake caused the collapse of a bridge, entrapping a child within a car. A through-knee amputation was required to free the patient with local anesthetic only. The second case was the result of a truck bomb causing the collapse of a building whereby a victim was trapped by a pillar. After retrieval of supplies from a local hospital, a through-knee amputation was performed. The third case involved a young man whose arm became entangled in an oil derrick. This patient was sedated and intubated in an erect position and the arm was amputated. Fortunately, each of these victims survived. However, the care these patients received was unplanned and had the potential for failure. The authors feel that disaster teams, including a surgeon, should be identified in advance as responders to a disaster on short notice. Legal issues including statespecific Good Samaritan laws and financial support systems must also be considered. As hospitals and trauma systems prepare for disaster situations, they should consider the eventuality of field dismemberment. This involves identifying a team, including a surgeon, and devising an infrastructure allowing rapid response capabilities, including surgical procedures in the field.

Strength Analysis and Calculation of JJ225/42-KC Type Oil Rig Derrick

Abstract. Oil rig derrick is a large and complex metal frame with lots of bars and complex force. Moreover, the use of working condition is complex and harsh, so it is quite necessary to analyze strength and calculate oil rig derrick. In this paper, with the basic structure and force characteristic of JJ225/42-KC type oil derrick, the ANSYS finite element software is used to establish JJ225/42-KC type oil derrick structure finite element model. The strength and stability analysis of the maximum hook load working condition, the working wind load working condition and the maximum wind load working condition of three combined working conditions indicates that the overall structural design of JJ225/42-KC type oil derrick is reasonable with good both dynamic and static characteristics and the derrick meets the requirements of the strength. What is more, the derrick has a excellent overall stability. In the end, the strength of the lifting devices and the derrick leg pin of JJ225/42-KC type oil derrick are calculated and checked, showing that all meet the requirements of the strength.

Oil in the City: The Fall and Rise of Oil Drilling in Los Angeles

82 The Journal of American History June 2012 Today oil derricks stand like trees in a forest. . . . Steam pile drivers roar on many a vacant lot. . . . One hundred and eighty permits to drill for oil have been given and twenty-five more are in procedure. . . . If this fever continues, as it gives every indication of doing, one reasonably may expect to see virtually the entire waterfront line of private properties from Washington street to Sixty-sixth avenue or Playa del Rey dotted with a line of oil derricks.

Cormac McCarthy and the Aesthetics of Exhaustion

Addressing the genre of Cormac McCarthy’s 1992 All the Pretty Horses, James Lilley writes that despite telling the story of its protagonist John Grady Cole’s journey from home and coming of age, the novel “is a Western, not a Bildungsroman” (274). “Whereas the Bildungsroman is driven forward by a quest for novelty,” Lilley writes, “Westerns are necessarily retrospective, repetitive and elegiac, driven by a desire to repeat and relive the established patterns and plots of the past” (274). Cole, whose story begins with his grandfather’s funeral in 1949 (6), and who travels not west but south across the Mexican border in search of something missing in his modern Texas of cars and oil derricks, “does not want to extricate himself from the past—establishing a new beginning, divorced of all precedent, on the frontier; rather, his journey down into Mexico becomes an elegy to the Old West, an attempt to move backwards in time to a place where the codes of the Old West are still valorized” (Lilley 274). Leaving aside the question of whether he conflates all Westerns with the particular sub-genre of belated Westerns that flourished during the mid-twentieth-century period in which All the Pretty Horses is set, Lilley’s curious distinction between the Western and narratives of new beginnings on the frontier is symptomatic of another implicit conflation, in this case of the Western with genre fiction as such. Arguing that John Grady returns to Texas at the end of the novel “fully aware that life, like the Western, is driven by repetition,” Lilley sees Grady as exemplifying McCarthy’s commitment to the sort of “freedom within the ultimately empty and determined symbols of language” described by Lacan (283). This reading of genre, with its stress on narrative and other forms of repetition,

Biological Response Signature of Oil Brine Threats, Sediment Contaminants, and Crayfish Assemblages in an Indiana Watershed, USA

The Patoka River watershed contains a divergent landscape of oil and gas exploration, intensive agriculture, and surface mining mixed with National Forest, Wildlife Refuges, and a large recreational reservoir. We evaluated species diversity among different land uses, including, commercial, forested, residential, and agriculture, and determined relationships among disturbance scale, habitat requirements, contaminants, and patterns in species distributions. Primary burrowing species, Cambarus polychromatus, Cambarus cf diogenes (Lacunicambarus A), and Fallicambarus fodiens, were tolerant of higher concentrations of contaminants than aquatic tertiary burrowing species. Cambarus polychromatus was among the last species of crayfish at the most disturbed sites, while it was absent from pasture and agricultural landscapes that allowed cattle access along banks. Four species of Orconectes were found in the reference and agricultural landscapes within the watershed, including O. immunis, O. indianensis, O. inermis inermis, and O. propinquus. Orconectes indianensis distribution was determined by the presence of rock habitat and absence of contaminants. No Orconectes species were found in acid mine leachate-affected streams with high levels of molybdenum. Cambarus laevis was found in the highest-quality reference areas, which were associated with karst habitats and no contaminants. Burrowing crayfish species were associated with the oil derricks in the lower and middle watershed, which contained increased concentrations of strontium, phosphorus, and various organic parameters associated with oil brine PAHs.

The Old-timers

On August 7, 2001, I stepped into the fiftieth anniversary celebration of the discovery of oil in Williston Basin, Williston, North Dakota. I knew no one. My family had not been back to the Williston Basin since the December night in 1960 when my father had run his car into a train—as squarely-hit as any the police had ever seen—and died. When I saw the anniversary announcement on the Internet, I bought a train ticket to Williston. I had to ride the train, it was the way my mother had come and gone from Mississippi to North Dakota and later, with her two little girls, to Denver. So in the early Memphis dawn, I stood on the train platform, close to the tracks, awaiting the City of New Orleans that would take me to Chicago. The train finally showed itself, far down the track, its front light white and piercing. Then the whistle cried. The snub-nosed engine—tall and heavy, its silver body blocking all view—screamed on the tracks. As the cars clattered into the station, slowing, I thought, you want me to get on that motherfucker? Hours later, when the sun had risen high in the sky, I gazed out the window, and in the flattened train flying beside the tracks, I saw the truth of it: we carry our own shadow with us. At the Airport International Inn in Williston, I paid my money and received my ticket to the headliner banquet. A table in the lobby displayed hand-made, wooden replicas of oil derricks. "For Sale" tags lay flat beside the derricks. On another table were chunky, metal drill bits, dressed up with black spray paint and tied in gold ribbon. "It was a big deal," my mother says of North Dakota's oil boom, but I saw a trifold display board and, thumbtacked to it, several newspaper articles [End Page 116] and a Xerox of the boom's first oil lease. In the hall that led to the banquet room hung portraits of Miss North Dakotas—the Airport International Inn was pageant headquarters. The portraits were cheap, almost Polaroid quality. Maybe the oil boom was a big deal—for rural, isolated North Dakota, even more so for a girl from rural, isolated Mississippi. Inside the banquet hall, lines of long tables angled in front of the crepe-skirted stage. A woman played a piano that had been rolled to the side of the stage. I'd seen the woman earlier when I was sitting in the lobby. "Everyone in their jewels," she'd said, talking about what to expect from the banquet crowd. What I saw in the crowd were the old-timers, the banquet honorees. Clumped together in groups of twos, then fours, then sixes, most of them were dressed in saggy-bottomed jeans and plain, unadorned cowboy boots. The cowboy poet, who was to be our entertainment, wandered through the crowd in new jeans, carrying a guitar. Around him, the white-haired old-timers gently milled and eddied, catching up after fifty years. I watched, not with the eyes of the forty-three-year-old woman I was, but with the eyes of the three-year-old daughter I'd been when my father died—the age, a psychiatrist would later tell me, when a girl child is most attached. There, in the Airport International Inn in North Dakota, I spied on the old-timers who might have known my dad. It's a long way from Mississippi to North Dakota. First, you travel to Memphis where you board the train, then it's twenty-seven hours, twenty-two minutes to North Dakota. To make the trip, you must hurtle between towns, survive the lurching of the cars, cast away your familiar loves. For when you're south of Chicago, the skinny pine trees, the stinkweeds growing beside the tracks—it looks like Mississippi. But when it's time for the Empire...

Resolutions of the 2001 Annual Meeting: Santa Barbara, California

RESOLUTIONS OF THE 2001 ANNUAL MEETING SANTA BARBARA, CALIFORNIA Introduction I s u s p e c t I h a v e b e e n a s k e d to deliver the humorous Resolutions part of the banquet because I come from so far away. If you come look­ ing for me, you'd better have a big parka. Because of the terrible tragedies of September 11, our hosts have had to make major changes in the program and arrangements almost on an hourly basis. They certainly deserve our gratitude for their efforts. Rather than begin with the funny things that have happened, permit me instead to start on a serious note. Please look at the one dollar bill and remember our American heritage of over two hundred years. There you will see the Great Seal of the United States of America with the symbol of our nation, the eagle. Note that his head is looking toward his right claw, in which he clasps the olive branch of peace. This symbolizes the words of Abraham Lincoln during a much greater crisis: "With charity to­ wards all and malice towards none." Let us not forget that now, as the eagle's head is turning toward his left claw containing the ter­ rible arrows of war. Right here in California that motto was forgotten in December 1941, to our great loss. Please carry these words home with you and share them with all: With charity towards all and malice towards none. Our Sense of Place We thought we had been invited to the Riviera of some place, probably south of Vandenburg AFB. At least the highway parallel­ ing the coast says "south," but I just watched the sunset, and actually the coast runs west-east. We thought we were invited to Santa Bar­ bara, but wound up near a place call Goleta. We thought we were at a university, but there are no students. Instead we enter this peninsula through a guard protecting a nar­ row neck of land, and the buildings have overhangs for the deflection of bombs. There are walls and gun pits everywhere, and the layout is designed to confuse an invader. In the middle there is a high watch177 178 APCG YEARBOOK • Volume 64 • 2002 tower, to look for enemies in all directions, and a large water-storage basin. There is also a training area for soldiers, including an arena for chariot races. This is a fortress, one Caesar would easily understand, which maybe is why the arena is named Cesar. We were carefully instructed that the key problem here is water, which is in short supply because so much of it is used to water lawns and special plants. As the water washes off the lawns, it so pollutes the beaches that you cannot swim. That actually is not a handicap, because the beach is a dangerous place for tourists anyway who are under assault by bicycles, roller blades, and even motorized scoot­ ers racing all over the place. We were taken to the places where the water comes from. To get there, you have to go through the favorite and protected official Santa Barbara plant: poison oak. The water has a most delightful aroma— hydrogen sulfide. This is why retired people here have no problem with "regularity." The hills we learned must periodically be burned off, which is only "natural," and that is why houses are all over the hills and are reached by narrow and twisting roads, which would prevent fire fighters from going anywhere. But these are good fires. Of course, when the heavy rains come after the fires, there are mudflows and floods all over this plain. Moreover, this whole area is cut by trans­ verse faults, so that it is a wonderful "Shake, Rattle, and Roll" place made more exciting by the fact that the whole region is being up­ lifted. Of course, there have been only four or five tsunamis, which help clean out the beaches. Now out in the harbor are oil derricks, which have punched holes at the top of an anticline. In Geology 01 we learned that oil wells should be dug along the sides...

Local Connections

This article discusses integration of microturbines with energy storage systems and fuel cells for the development of new applications in distributed energy generation. Williams Energy Services integrated two Capstone Model 330 microturbines and one PowerBlock energy storage system to power an oil derrick near the Denver airport. A key microturbine component is its recuperator, which transfers heat from exhaust gas to air that is sent to the combustor. Preheating combustion air reduces the fuel consumption of the microturbine and increases its overall efficiency. One hybrid microturbine power plant now in commercial service was developed by Williams Distributed Power Services of Tulsa, Oklahoma. The Williams energy conversion unit (ECU) incorporates two Model 330-kilowatt microturbines developed by Capstone Turbine Corp. of Woodland Hills, California, and the PowerBlock energy storage device developed by Powercell Corp. of Burlington, MA. The ECU provides reliable 480-volt power when the grid power to the oil field is interrupted.
