    The Resident Fish Stock Status above Chief Joseph and Grand Coulee Dams Project, commonly known as the Joint Stock Assessment Project (JSAP) is a management tool using ecosystem principles to manage artificial fish assemblages and native fish in altered environments existing in the Columbia River System above Chief Joseph and Grand Coulee Dams (blocked area). The three-phase approach of this project will enhance the fisheries resources of the blocked area by identifying data gaps, filling data gaps with research, and implementing management recommendations based on research results. The Blocked Area fisheries information housed in a central location will allow managers to view the entire system while making decisions, rather than basing management decisions on isolated portions of the system. The JSAP (NWPPC program measure 10.8B.26) is designed and guided jointly by fisheries managers in the blocked area and the Columbia Basin blocked area management plan (1998). The initial year of the project (1997) identified the need for a central data storage and analysis facility, coordination with the StreamNet project, compilation of blocked area fisheries information, and a report on the ecological condition of the Spokane River System. These needs were addressed in 1998 by acquiring a central location with a data storage and analysis system, coordinating a pilot project with StreamNet, compiling fisheries distribution data throughout the blocked area, identifying data gaps based on compiled information, and researching the ecological condition of the Spokane River. In order to ensure that any additional information collected throughout the life of this project will be easily stored and manipulated by the central storage facility, it was necessary to develop standardized methodologies between the JSAP fisheries managers. The use of common collection and analytical tools is essential to the process of streamlining joint management decisions. In 1999 and 2000 the project

    In 1980, the United States Congress enacted the Northwest Power Planning and Conservation Act (PL 96-501, 1980), which established the Northwest Power and Conservation Council (NPCC), formerly the Northwest Power Planning Council. The NPCC was directed by Congress to develop a regional Power Plan and also the Columbia River Basin Fish and Wildlife Program (FWP) to restore or replace losses of fish caused by construction and operation of hydroelectric dams in the Columbia River Basin. In developing the FWP, Congress specifically directed NPCC to solicit recommendations for measures to be included in the Program from the region's fish and wildlife agencies and Indian tribes. All measures adopted by the Council were also required to be consistent with the management objectives of the agencies and tribes [Section 4.(h)(6)(A)], the legal rights of Indian tribes in the region [Section 4.(h)(6)(D)] and be based upon and supported by the best available scientific knowledge [Section 4.(h)(6)(B)]. The Resident Fish Stock Status above Chief Joseph and Grand Coulee Dams Project, also known as the Joint Stock Assessment Project (JSAP) specifically addresses NPPC Council measure 10.8B.26 of the 1994 program.

    Since 1995, the Confederated Tribes of the Colville Reservation (Colville Confederated Tribes) have managed the Chief Joseph Kokanee Enhancement Project as part of the Northwest Power Planning Council (NWPPC) Fish and Wildlife Program. Project objectives have focused on understanding natural production of kokanee (a land-locked sockeye salmon) and other fish stocks in the area above Grand Coulee and Chief Joseph Dams on the Columbia River. A 42-month investigation concluded that entrainment at Grand Coulee Dam ranged from 211,685 to 576,676 fish annually. Further analysis revealed that 85% of the total entrainment occurred at the dam's third powerplant. These numbers represent a significant loss to the tribal fisheries upstream of the dam. In response to a suggestion by the NWPPC Independent Scientific Review Panel, the scope of work for the Chief Joseph Kokanee Enhancement Project was expanded to include a multiyear pilot test of a strobe light system to help mitigate fish entrainment. This report details the work conducted during the second year of the study by researchers of the Colville Confederated Tribes in collaboration with the Pacific Northwest National Laboratory. The 2002 study period extended from May 18 through July 30. The objective of the study was to determine the efficacy of a prototype strobe light system to elicit a negative phototactic response in kokanee and rainbow trout. The prototype system consisted of six strobe lights affixed to an aluminum frame suspended vertically underwater from a barge secured in the center of the entrance to the third powerplant forebay. The lights, controlled by a computer, were aimed to illuminate a specific region directly upstream of the barge. Three light level treatments were used: 6 of 6 lights on, 3 of 6 lights on, and all lights off. These three treatment conditions were applied for an entire 24-hr day and were randomly assigned within a 3-day block throughout the study period. A seven

    The construction of Grand Coulee and Chief Joseph dams on the Columbia River resulted in the complete extirpation of the anadromous fishery upstream of these structures. Today, this area is totally dependent upon resident fish resources to support local fisheries. The resident fishing is enhanced by an extensive stocking program for target species in the existing fishery, including kokanee (Oncorhynchus nerka kennerlyi) and rainbow trout (O. mykiss). The kokanee fishery in Lake Roosevelt has not been meeting the return goals set by fisheries managers despite the stocking program. Investigations of physical and biological factors that could affect the kokanee population found predation and entrainment had a significant impact on the fish population. In 1999 and 2000, walleye (Sander vitreum) consumed between 15% and 9%, respectively, of the hatchery kokanee within 41 days of their release, while results from a study in the late 1990s estimated that entrainment at Grand Coulee Dam could account for up to 30% of the total mortality of the stocked fish. To address the entrainment loss, the Bonneville Power Administration commissioned a study to determine if fish would avoid areas illuminated by strobe lights in the forebay of the third powerplant. This work was conducted by Pacific Northwest National Laboratory (PNNL) in conjunction with the Confederated Tribes of the Colville Reservation (Colville Confederated Tribes). From 2002 through 2004, six strobe lights were suspended in the center of the opening to the third powerplant forebay during summer months. Results from those studies indicated that fish appeared to be attracted to the illuminated area but only at night and when flow conditions within the third powerplant forebay were minimal. However, small but consistent results from these studies indicated that under high flow conditions, fish might be avoiding the lights. The 2005 study was designed to examine whether, under high flow conditions near the penstock

    This report describes a study conducted by Pacific Northwest National Laboratory (PNNL) for the Bonneville Power Administration to characterize the conditions fish experience when entrained in pump flow at the Grand Coulee Dam. PNNL conducted field studies at Grand Coulee Dam in 2004 using the Sensor Fish to measure the acceleration and pressure conditions that might be experienced by fish that pass through pumps at Grand Coulee Dam's Pump-Generating Plant and are transported up into the feeder canal leading to Banks Lake. The probability that fish would be struck by the Pump-Generating Plant's new nine-bladed turbines was also estimated. Our measurements showed relatively low turbulence except in the immediate vicinity of the runner environment. The lowest and highest pressures experienced by the Sensor Fish were 6.4 and 155 psi (the pressure gauge saturated at 155 psi). The probability of strike was also calculated, based on the average length of hatchery-reared juvenile kokanee (land-locked sockeye). Strike probabilities ranged from 0.0755 for 2.36-inch fish to 0.3890 for 11.8-inch fish. The probability of strike estimates indicate that the majority (77%) of recently released hatchery kokanee would be carried through the test pump without being struck and most likely with low risk of injury resulting from pressure and turbulence exposure. Of the 23% that might be struck it is expected that 60% would arrive in Banks Lake without visible external injuries. Thus more than 90% of entrained fish could be expected to arrive in Banks Lake without significant injury, assuming that no kokanee were injured or killed by pressure exposure during passage.

    In the early 1980's the Confederated Tribes of the Colville Reservation, the Spokane Tribe of Indians and the Washington Dept. of Fish and Wildlife developed a management plan for Lake Roosevelt on the restoration and enhancement of kokanee salmon populations using hatchery out plants and the restoration of natural spawning runs. The plan was incorporated into the Northwest Power Planning Council (NPPC) in their 1987 Columbia Basin Fish and Wildlife program as partial mitigation for hydropower caused fish losses resulting from the construction of Grand Coulee Dam. The Chief Joseph Kokanee Enhancement Project, as part of a basin wide effort, is evaluating the status of the natural production kokanee in streams tributary to Lakes Roosevelt and Rufus Woods and is examining entrainment through Grand Coulee Dam. The goal of this project is the protection and enhancement of the natural production kokanee in these two lakes. The project is currently collecting data under four phases or parts. Since 1991, Lake Whatcom Washington origin kokanee have been planted in considerable numbers into the waters of Lake Roosevelt. A natural production kokanee fishery has persisted in the lake since the early 1970's(Cash, 1995), (Scholz, 1991). Historical information alludes to wild Kokanee production in the San Poil River, Nespelem River, Big Sheep Creek, Ora-Pa-Ken Creek, Deep Creek and Onion Creeks. The genetic makeup of the fish within the fishery is unknown, as is their contribution to the fishery. The level of influence by the hatchery out planted stock on wild fish stocks is unknown as well. Project outcomes will indicate the genetic fitness for inclusion of natural production kokanee stocks into current Bonneville Power Administration funded hatchery programs. Other findings may determine contribution/interaction of/between wild/hatchery kokanee stocks found in the waters of Lake Franklin D. Roosevelt.

    2003-01-01

    In 1995, the Chief Joseph Kokanee Enhancement Project was established to mitigate the loss of anadromous fish due to the construction of Chief Joseph and Grand Coulee dams. The objectives of the Chief Joseph Enhancement Project are to determine the status of resident kokanee (Oncorhynchus nerka) populations above Chief Joseph and Grand Coulee dams and to enhance kokanee and rainbow trout (Oncorhynchus mykiss) populations. Studies conducted at Grand Coulee Dam documented substantial entrainment of kokanee through turbines at the third powerhouse. In response to finding high entrainment at Grand Coulee Dam, the Independent Scientific Review Panel (ISRP) recommended investigating the use of strobe lights to repel fish from the forebay of the third powerhouse. Therefore, our study focused on the third powerhouse and how strobe lights affected fish behavior in this area. The primary objective of our study was to assess the behavioral response of kokanee and rainbow trout to strobe lights using 3D acoustic telemetry, which yields explicit spatial locations of fish in three dimensions. Our secondary objectives were to (1) use a 3D acoustic system to mobile track tagged fish in the forebay and upriver of Grand Coulee Dam and (2) determine the feasibility of detecting fish using a hydrophone mounted in the tailrace of the third powerhouse. Within the fixed hydrophone array located in the third powerhouse cul-de-sac, we detected 50 kokanee and 30 rainbow trout, accounting for 47% and 45% respectively, of the fish released. Kokanee had a median residence time of 0.20 h and rainbow trout had a median residence time of 1.07 h. We detected more kokanee in the array at night compared to the day, and we detected more rainbow trout during the day compared to the night. In general, kokanee and rainbow trout approached along the eastern shore and the relative frequency of kokanee and rainbow trout detections was highest along the eastern shoreline of the 3D array. However, because we

    Joseph Henry (1797-1878) is best known for his work in electromagnetism and as the first secretary of the Smithsonian Institution. But he was also a pioneer solar physicist, an early advocate of US participation in astrophysics, and a facilitator of international cooperation in astronomy. This paper will briefly trace his role in the development of the US astronomical community from the time he taught astronomy at Princeton in the 1830s through his death, focusing on failed efforts to persuade US astronomers and patrons of astronomy that the best path for US astronomy should be astrophysics. He thought that the US could make a more significant contribution to astronomy science by striking out on a less travelled path rather than competing with the established European observatories.

However, he preferred to refer to himself as a philosophical botanist, rather than a professional. This paper explores the reasons for this choice, and analyses Hooker’s imperial approach to plant classification, the consequences of which are still with us.

  9. Narrator-in-Chief

    DEFF Research Database (Denmark)

    Herron, Mark A.

    The dissertation Narrator-in-Chief: The Narrative Rhetoric of Barack Obama seeks to show how the concept of “narrative” can be used in rhetorical criticism of presidential speeches, particularly when considering the speeches and the biographical text, Dreams from My Father (1995), of Barack Obama....... The use of narratives of and by presidents in the White House can be seen as an essential part of the ceremonial role of the presidency. This use of narratives in epideictic speech has increased with modern day interests in the domestic life of the president, and the use of visual mass media...... as a communication platform for the president. While this has been described as a negative development (Stuckey, 1991; Salmon, 2010) this dissertation argues that narrative rhetoric should not be seen only as a negative part of political rhetoric, but also as a possibly vital way to educate the audience on issues...

    The idea of describing animal movement by mathematical models based on diffusion and Brownian motion has a long heritage. It has thus been natural to account for those aspects of motion that depart from the Brownian by the use of models incorporating long memory & subdiffusion (“the Joseph effect”) and/or heavy tails & superdiffusion (“the Noah effect”). My own interest in this problem was originally from a geoscience perspective, and was triggered by the need to model time series in space physics where both effects coincide. Subsequently I have been involved in animal foraging studies [e.g. Edwards et al, Nature, 2007]. I will describe some recent work [Watkins et al, PRE, 2009] which studies how fixed-timestep and variable-timestep formulations of anomalous diffusion are related in the presence of heavy tails and long range memory (stable processes versus the CTRW). Quantities for which different scaling relations are predicted between the two approaches are of particular interest, to aid testability. I will also present some of work in progress on the convex hull of anomalously diffusing walkers, inspired by its possible relevance to the idea of home range in biology, and by Randon-Furling et al’s recent analytical results in the Brownian case [PRL, 2009].

  11. Joseph Haydn's encephalopathy: new aspects.

    2015-01-01

    With increasing age, Joseph Haydn complained of progressive forgetfulness preventing him from composing for about the last 8 years of his life. He spent his days more and more inactive and immobilized, suffering from a disabling gait disturbance. Still, most biographers consider diffuse atherosclerosis and congestive heart failure to be reasons for Haydn's medical condition and physical decline during the last years of his life. A more sophisticated and detailed inspection of documents and sources, however, leads to the diagnosis of subcortical vascular encephalopathy (SVE), caused by progressive cerebral small vessel disease. Important features of the disease are mood changes, urinary symptoms, and in particular a characteristic gait disturbance, while dementia is only mild and occurs later in the course. Haydn was severely disabled by the symptoms of SVE for several years and often reported difficulties in the completion of his last oratorio "Die Jahreszeiten" (The Seasons). Subsequently, the disease prevented him from composing another large oratorio, "Das jüngste Gericht" (The last judgement), which had been already drafted. Finally, the progress of SVE stopped his long career as a composer and conductor at the age of 73 years. PMID:25684297

The title was "The Statistical Mechanics of Condensing Systems. I," the abstract of this paper is given below: It is shown that for a system composed of N identical molecules with mutual potential energy, the assumption that the total potential energy can be expressed as the sum of that between pairs of molecules allows the derivation of simple, accurate formal equations for the thermodynamic properties of the system. Under certain conditions, generally fulfilled at low temperatures, the equations predict a region where the pressure and Gibb's free energy are independent of volume, the characteristic of condensing sytems. The equations permit calculation of the Gibb's free energy of the liquid in equilibrium with the vapor and all the properties of the saturated vapor, but not the volume or volume dependence of the condensed phase...

  15. Joseph Conrad's tormented Rescue (fantasy).

    Science.gov (United States)

    Freedman, William

    2014-02-01

    Joseph Conrad was a notoriously tormented writer for whom the creative act was often a punishment severe enough to drive him into paralyzing depressions that delayed the completion of his novels, sometimes for years. By far the most agonizing of these projects was The Rescue, a novel he began in 1898, abandoned a year later, tried unsuccessfully to continue several times over the next two decades, but was only able to resume in 1918 and to complete, after another tortured two-year struggle, in 1920. An explanation for this incapacity, that is powerfully suggested by the novel's evocative title and perhaps unintentionally ironic subtitle (A Romance of the Shallows) has not yet been explored. Using Freud's 1910 essay on the rescue fantasy, "Contributions to the Psychology of Love: A Special Type of Choice of Object Made by Men," and Emanuel Berman's instructive revision and expansion of the concept in his 2003 American Imago essay, "Ferenczi, Rescue, and Utopia," I argue that a substantial explanation for Conrad's tormented history with The Rescue is ascribable to its quite remarkably faithful treatment of a rescue fantasy with deep and disabling resonance for its author. More specifically, the difficulty was compounded by the novel's dramatization of the soul-crushing conflict between two such fantasies: one in the service of the masculine ideal of unflinching dedication to a heroic purpose, the other promising satisfaction to the equally potent demands of emotional and sexual desire. Features of Conrad's narrative fit so tightly and consistently with the theory as Freud (and Abraham) proposed and as Berman elaborated it that The Rescue offers itself as one of those rare and reinforcing instances wherein the literary text seems to validate the psychoanalytic theory at least as persuasively as the theory "understands" the text.

    They're nominally and ultimately responsible for strategy, but today's CEOs have less and less time to devote to it. As a result, CEOs are appointing "chief strategy officers"--executives specifically tasked with creating, communicating, executing, and sustaining a company's strategic initiatives. In this article, three authors from Accenture share the results of their research on this emerging organizational role. The typical CSO or top strategy executive is not a pure strategist, conducting long-range planning in relative isolation. Most CSOs consider themselves doers first, with the mandate, credentials, and desire to act as well as advise. They are seasoned executives with a strong strategy orientation who have usually worn many operations hats before taking on the role. Strategy executives are charged with three critical jobs that together form the very definition of strategy execution. First, they must clarify the company's strategy for themselves and for every business unit and function, ensuring that all employees understand the details of the strategic plan and how their work connects to corporate goals. Second, CSOs must drive immediate change. The focus of the job almost always quickly evolves from creating shared alignment around a vision to riding herd on the ensuing change effort. Finally, a CSO must drive decision making that sustains organizational change. He or she must be that person who, in the CEO's stead, can walk into any office and test whether the decisions being made are aligned with the strategy and are creating the desired results. When decisions below the executive suite aren't being made in accordance with strategy, much of the CSO's job involves learning why and quickly determining whether to stay the course or change tack.

    During his distinguished career, Dan Joseph worked on a vast array of problems. One of these, which occupied him off and on over the last two decades of his life, was that of flows with suspended finite-size particles at finite Reynolds numbers. He realized early on that progress in this field had to rely on the insight gained from numerical simulation, an area in which he was a pioneer. On the basis of the early numerical results he recognized the now famous ``drafting, kissing and tumbling'' mechanism of particle-particle interaction, the possibility of fluidization by lift and many others. With a number of colleagues and a series of gifted students he produced a significant body of work summarized in his on-line book Interrogations of Direct Numerical Simulation of Solid-Liquid Flows available from http://www.efluids.com/efluids/books/joseph.htm. This presentation will describe Joseph's contribution to the understanding of disperse multiphase flow and conclude with some examples from the author's recent work in this area. Supported by NSF.

    Full Text Available Salvation: from Pelagius to Joseph Smith Every Christian church believes that she is a true church and proclaims that man can be saved and has eternal life. This dogma of salvation is usually based on the Bible as the Word of God. Mormons claim that Joseph Smith, founder and first president of the Church of Jesus Christ of Latter Day Saints, received a divine message to restore the church that Jesus had started.  In studying the plan of salvation the Mormons proclaim it is quite clear that that way of salvation was not restored in their church, but that it followed a pattern of false doctrine that was revealed time and again in history.  The core of their preaching of salvation is that man has the free will to choose his own salvation. Mormons are not the first to preach this message. This article will show that Pelagius oisty-kated the free will of man. In the Reformation the Anabaptists preached the same message, being a third movement next to the reformed and Roman Catholic believes. The Anabaptists became part of the churches of the Netherlands and at the Synod of Dordt the theology of the free will was rejected and answered.  The dogma of the free will of man did not end at this Synod: 150 years later John Wesley preached the same message of salvation during his and Whitefield’s campaigns at the dawn of the nineteenth century in the USA.  During this time Joseph Smith started to seek the true church and founded the Mormon Church. Although his theology differs quite strongly from the Methodist Church in which he grew up, the core of the way of salvation is the same: man has free will in choosing his salvation.

    Full Text Available Les barrages-réservoirs de montagne ont été réalisés initialement dans les Alpes pour répondre à la demande d’énergie en période hivernale. Une certaine diversification des usages de l’eau s’est ensuite progressivement développée, en relation avec le développement touristique des collectivités locales. Aujourd’hui, la participation des ouvrages d’Électricité De France à la production de neige de culture représente une nouvelle étape. Dans les régions où les aménagements hydroélectriques sont nombreux, les besoins en eau pour la production de neige peuvent être résolus par prélèvements à partir des adductions EDF. Les gestionnaires de stations échappent ainsi aux inconvénients liés à la construction et à la gestion des « retenues collinaires ». Cette évolution, qui concerne déjà quelques régions alpines comme la haute Maurienne ou le Beaufortin, apparaît comme une forme renouvelée d’intégration territoriale de la ressource en eau.Mountain reservoirs were initially built in the Alps to meet energy needs in the winter. A certain diversification in the uses of water then gradually developed, related to tourism development in the local communities. Today, the use of facilities belonging to EDF (French Electricity Authority to provide water for winter resorts to make artificial snow represents a new phase. By taking water from EDF resources to supply snow-making equipment, resort managers are thus able to avoid the problems related to the construction and management of small headwater dams. This new orientation in the use of mountain water resources already affects a number of alpine regions such as the Upper Maurienne valley and Beaufortain massif and represents a renewed form of the territorial integration of water resources.

This article describes the structure and outcomes for an eight-month leadership development program for chief residents conducted over the past three years at the University of Iowa Hospitals & Clinics (UIHC, USA. Additionally, it provides keys to success and logistical issues for any institution that is considering a similar program. Innovation. Current chiefs must formally apply in late August. Sessions are held on the second Tuesday of each month for two hours. Facilitators guide each session in such a manner that they allow participants to do most of the discussion. Facilitators also provide opportunities for insight from other chiefs, and provoke deeper understanding of behaviors or thoughts. Eight topics are covered during the year with intersession assignments. Additionally, chiefs are required to attend 75% of the sessions, develop a leadership philosophy, and conduct some type of leadership presentation within their own department. Evaluation. Each year since 2010, the number of participating chiefs has risen (6, 9, 9. Evaluation data indicates a marked increase in before and after leadership knowledge and self-awareness. Additionally, chiefs have reported positive behavioral impacts regarding their leadership. Chiefs are the best advertising source for the program. Conclusions. The leadership program continues to evolve and evaluation results indicate that the content is instructive and the format is supportive for participants. Most chiefs recommend it highly for future chiefs.

Between 1880 and 1930, Wichita Falls entrepreneur Joseph Kemp dreamed of an agrarian Eden on the Texas rolling plains. Kemp promoted reclamation and conservation and envisioned the Big Wichita River Valley as the "Irrigated Valley." But the process of bringing dams and irrigation ditches to the Big Wichita River ignored knowledge of the river and local environment, which ultimately was key to making these complex systems work. The boosters faced serious ecological limitations and political obstacles in their efforts to conquer water, accomplishing only parts of the grandiose vision. Ultimately, salty waters and poor drainage doomed the project. While the livestock industry survived and the oil business thrived in the subsequent decades, the dream of idyllic irrigated farmsteads slowly disappeared.

    Small dams are often used for irrigation, municipal water supplies and storm water management. Small dams outnumber large hydro-electric projects in Canada by a wide margin, and tend to be located closer to large population centres. Despite their lower profile with the general public, small dams frequently have high consequence classifications. This study discussed the distribution of various consequence classifications for small dams of varying heights. Databases from different Canadian provinces were used to develop sets of statistics on dam features, the distribution of risk, and other relevant information. Approximately 6000 dams were classified in the database. Of these, 444 were greater than 15 metres in height. A significant portion of with high consequence classifications qualified as small dams, and the majority of the high consequence dams were under 10 metres in height. The largest population of dam owners have limited resources available for adequate engineering design, construction supervision, and dam safety management programs. It was concluded that economical methods of estimating probable maximum flood (PMF) rates are needed for small dams. 8 refs., 5 tabs., 2 figs.

    Studies which promote the use of nuclear energy for peaceful projects in engineering are sponsored by the Atomic Energy Commission under the Plowshare program. Specific projects being considered include the construction of harbors, canals, and dams. Of these projects, perhaps the most difficult to accomplish will be the latter. This paper which is in two parts considers the problems which are associated with the construction of slide dams with nuclear explosives. It examines first the characteristics of conventional earth and rock-fill dams which are based upon proven techniques developed after many years of experience. The characteristics of natural landslide dams are also briefly considered to identify potential problems that must be overcome by slide dam construction techniques. Second, the mechanics of slide dams as determined from small-scale laboratory studies are presented. It is concluded that slide dams can be constructed and that small-scale field tests and additional laboratory studies are justified. (author)

    The purpose of dam safety is to prevent an uncontrolled release of water and to have emergency preparedness plans in place in the event of failure. This presentation discussed dam and public safety around dams. Public safety around dams involves the safe management of water during normal operations, including intake water; discharge from turbines; and spill events. Public safety measures are intended to ensure the security of the site to minimize public exposure to hazards. The objectives of the presentation were to discuss the current state of industry practice in regards to public safety around dams and to provide input to the draft Canadian Dam Association guidelines for public safety around dams. The presentation also discussed the principles that would govern preparation of the guidelines and regulator's views on the public safety issues. figs.

    A guideline intended for conventional dams such as hydroelectric, water supply, flood control, or irrigation is used sometimes for evaluating the safety of a tailings dam. Differences between tailings dams and conventional dams are often substantial and, as such, should not be overlooked when applying the techniques or safety requirements of conventional dam engineering to tailings dams. Having a dam safety evaluation program developed specifically for tailings dams is essential, if only to reduce the chance of potential errors or omissions that might occur when relying on conventional dam engineering practice. This is not to deny the merits of using the Canadian Dam Safety Association Guidelines (CDSA) and similar conventional dam guidelines for evaluating the safety of tailings dams. Rather it is intended as a warning, and as a rationale underlying basic requirement of tailings dam emgineering: specific experience in tailings dams is essential when applying conventional dam engineering practice. A discussion is included that focuses on the more remarkable tailings dam safety practics. It is not addressed to a technical publications intended for such dams, or significantly different so that the use of conventional dam engineering practice would not be appropriate.

Joe's major contributions to psychology vary widely, as mentioned, but they are all carefully connected to a rigorously humanistic understanding of the person. It may be stretching it to use the phrase "one of the last grand theorists" to describe him and his contribution to psychology. There are still many important living theorists in the field. However, it is not an exaggeration to use the term "grand" because Rychlak's work is nothing if not subsuming, spanning not only the personality and psychotherapy literatures but also works on cognition, humanism, and the philosophy of science. Throughout his long and productive examination of these ideas, Joe remained a man of the highest integrity, vision, and caring.

    Fourty public dams are managed on a real-time basis by the Centre d'expertise hydrique du Quebec (CEHQ). This presentation described the public dams owned by the CEHQ and discussed the public safety measures at the dams. The dams serve various purposes, including protection against floods; industrial or drinking water supply; resort or recreational activities; hydroelectric development; and wildlife conservation. Trigger events were also discussed, such as the complaint at Rapides-des-Cedres dam and deaths that occurred in 2004 when water from a dam was released without warning. Several photographs were presented to illustrate that people were unaware of the danger. Initiatives aimed at raising awareness and studying public safety issues were discussed. A pilot project was launched and a permanent committee was created to evaluate all aspects of public safety at the dams owned by CEHQ. The first tasks of the committee were to establish requirements for waterway safety barriers, both upstream and downstream, for all public dams; to establish requirements for safety signage for all public dams; and to develop criteria to decide on safety signage at each dam. figs.

    Full Text Available Editor-in-chief (C. 3 Dear readers and authors of the journal "Asymmetry"! Summer and beginning of autumn is traditionally not only the time for vacations, but also a variety of conferences. I participated in the 21st world Congress of neurology held in late September in Vienna. In his many papers were devoted to various, for the most part, practically important issues neurology. While the theoretical aspects of neurology, one way or another, was also highlighted at the Congress, including the issues of asymmetry. I would like to highlight two areas. First of all, pay attention to enchanting lecture Nobel laureate E. Candela "Vienna and the age of insight", in which E. Kandel told about the influence of art Nouveau on the work of Z. Freud in psychoanalysis. (More about this can be found in the Facebook log "Asymmetry" - https://www.facebook.com/jasymmetry.

Another direction was reflected in the plenary lecture M Chilca "Stroke and autonomic nervous system. The lecture was directly associated survival after stroke in the basin of the carotid arteries with damage to the cortical representation of the autonomic nervous system, which, as you wrote about it, including, and in our magazine, also asymmetrically. When left hemispheric stroke the medial prefrontal cortex and the insulin are observed less pronounced change in the characteristics of the cardiovascular system, compared to the same right hemispheric strokes. This lecture aroused great interest. Thus, we see the development of the research two types of asymmetries, which in some cases are conducted in parallel: cognitive and autonomic asymmetry. "Vegetative" asymmetry is much less studied, although its contribution to the clinic, sports medicine and pedagogy can be very serious. I wish the readers of the

    2014-01-01

    In the dense theological thought of Joseph Ratzinger before his election as pope, we find fundamental contributions to contemporary bioethics. Starting from the assumption of the close relationship between faith and science he incorporates a necessary theological dimension in the bioethical dialogue that illuminates and clarifies the answers to the real questions raised in bioethical actions. On the one hand, there is the question of the origin of man that is understood as God's creation as opposed to a purely biological origin to which a modern pseudoscientific stance wants to confine it. On the other hand, there is the question about man's identity, which is understood as the image of God, from which stems the inviolable dignity and sacredness of human life, overcoming scientistic materialism. Finally, we find the question of how to treat the ″other″, even the embryo, as a result of its lofty dignity, analyzing the ethical and legal consequences that exude from their nature and are summarized in the duty to protect and respect the other which the law should protect against the abuse of those who are stronger.

    A detailed search and re-evaluation of the known historical cases of tailings dam failure was carried out. A corpus of 147 cases of worldwide tailings dam disasters, from which 26 located in Europe, was compiled in a database. This contains six sections, including dam location, its physical and constructive characteristics, actual and putative failure cause, sludge hydrodynamics, socio-economical consequences and environmental impacts. Europe ranks in second place in reported accidents (18%), more than one third of them in dams 10-20 m high. In Europe, the most common cause of failure is related to unusual rain, whereas there is a lack of occurrences associated with seismic liquefaction, which is the second cause of tailings dam breakage elsewhere in the world. Moreover, over 90% of incidents occurred in active mines, and only 10% refer to abandoned ponds. The results reached by this preliminary analysis show an urgent need for EU regulations regarding technical standards of tailings disposal.

  12. Tailings dams safety - implications for the dam safety community

    International Nuclear Information System (INIS)

    In the context of the impact of privatization and globalization on traditional dam safety practice and the Canadian experience of the environmental dimension of dam failures, various aspects of tailings dam safety have much to offer the wider dam safety community. General design principles for tailings dams are not described, rather an attempt is made to frame some contemporary issues of tailings dam safety in ways that bring out their relevance in a broader dam safety context. Lessons applicable to future dam safety practice in related areas are examined, and the dam safety traditions of the mining, hydroelectric and related industries in Canada are brought together by illustrating some of the common elements and concerns they share. It is becoming evident that future dam safety activities for the hydroelectric, water supply and related dams will be carried out in a more privatized and globalized context by organizations less acquainted with traditional dam safety practices than in the past. If so, then tailings dam experience can be a pathfinder for how and why dam safety needs to be addressed in a corporate setting. It shows that the perceived effects of dam failures, environmental and otherwise, influence corporate damowners in ways that can amplify manyfold the objective consequences that dam safety assessments usually address. Dam safety professionals might do well to better understand and effectively communicate the financial and organizational impacts of dam failure on the corporate entity in ways that go beyond the traditional assessment of downstream hazard and failure consequences. Dam safety efforts can come to be seen less as imposed burdens of dam ownership and more as activities consistent with shareholder accountability and corporate self-interest. The Canadian mining industry, in adopting this perspective, is confirming that support for dam safety activities from the highest corporate level is essential for implementing them throughout the

    2009-07-01

    Ontario's current dam safety program is administered under guidelines and there is no regulation in place. It is a reactive program that is administered by area supervisors and regional engineers with support from policy, legal and enforcement branches. Currently, there are no regulatory requirements for inspections, dam classifications, public safety measures, emergency preparedness plans, operations and maintenance, or dam registration. This presentation proposed improvements to Ontario's current dam safety program and highlighted the imperatives for public safety around dams. The presentation also discussed the proposed elements of enhanced public safety requirements. The proposed measures would involve moving from a reactive, guidelines-based program to a regulated program under the Lakes and Rivers Improvement Act. The presentation discussed why public safety around dams should be regulated and provided an overview of dam related fatalities in Ontario. A public safety framework and public safety assessment report were also discussed. Registration of incidents and public safety measures were addressed. figs.

    Gainers and Losers are always associated with large scale hydrological infrastructure construction, such as dams, canals and water treatment facilities. Since most of these projects are public services and public goods, Some of these uneven impacts cannot fully be solved by markets. This paper tried to explore whether the governments are paying any effort to balance the uneven distributional impacts caused by dam construction or not. It showed that dam construction brought an average 2% decrease in per capita tax revenue in the upstream counties, a 30% increase in the dam-location counties and an insignificant increase in downstream counties. Similar distributional impacts were observed for other outcome variables. like rural income and agricultural crop yields, though the impacts differ across different crops. The paper also found some balancing efforts from inter-governmental transfers to reduce the unevenly distributed impacts caused by dam construction. However, overall the inter-governmental fiscal transfer efforts were not large enough to fully correct those uneven distributions, reflected from a 2% decrease of per capita GDP in upstream counties and increase of per capita GDP in local and downstream counties. This paper may shed some lights on the governmental considerations in the decision making process for large hydrological infrastructures.

    2014-06-01

    Full Text Available In most of the cases, the materials are tested in laboratories and designs are based on assumptions that the same results will be met with, during actual construction. As there are always large variations in materials, their properties, construction methods and their control, the actual product defers from the original assumptions. In this paper, instruments required to check the behaviour and stability of dams are discussed with their necessity, use and operation. These instruments prove to be much useful in proper maintenance of dam, and hence they should be installed under the guidance of experts at appropriate places in the dam. A conclusion has been arrived that there should be close co-operation between the designers, instrumentation specialist, expert analysis and site authorities to achieve the goal of instrumentation.

    2004-12-01

    Richard Joseph Elston, known for his development of innovative astronomical instrumentation, died on 26 January 2004 in Gainesville, Florida, after a four-year battle with Hodgkin's lymphoma. A professor of astronomy at the University of Florida, Richard had an unusually broad range of interests and skills, and a willingness to share his passion for astronomy with others, which made him a highly valued member of the astronomical community. Born 1 July 1960, in Albuquerque, New Mexico, Richard was the son of a geologist father and journalist mother. His childhood interest in astronomy and instrumentation matured as he majored in physics and astronomy at the University of New Mexico (BS, 1983) under the mentorship of Michael Zeilik. Richard pursued his PhD in astronomy at the University of Arizona and earned his degree in 1988. He pioneered the use of IR arrays for deep imaging surveys of the sky to study galaxy formation, and completed his thesis Search for Rapidly Forming Galaxies at High Redshift under the direction of George Rieke. Richard's graduate work included the first detection of galaxies at intermediate redshifts with evolved populations too red to have been identifiable from optical imaging surveys alone. In the Astrophysical Journal Letters in 1988, he, George Rieke, and Marcia Rieke reported the discovery of this new class of galaxies, now known as EROs (Extremely Red Objects), important as the possible progenitors of present day elliptical galaxies. Following post-doctoral positions at Kitt Peak National Observatory from 1988 to 1991 and at the Observatories of the Carnegie Institution of Washington from 1991 to 1992, Richard joined the scientific staff of Cerro Tololo Inter-American Observatory in Chile, part of the NSF's National Optical Astronomy Observatory. By 1994, he had become head of CTIO's IR instrumentation program and was leading the development of new instruments for the US astronomical community. In 1996, Richard married astronomer

There was no doubt that both Joe and his elder brother Gilbert would also become doctors, but Joe's first class in comparative anatomy at the University of Missouri convinced him that this was not his destiny and he immediately switched to physics and astronomy. He obtained a Masters degree in physics and moved on to the University of Michigan; his advisor was Lawrence Aller and he was also strongly influenced by Leo Goldberg. Early in 1952 he was awarded a PhD and began work at the Air Force Cambridge Research Center where he changed his interests to the upper atmosphere. Among his duties was liaison with research groups at several universities, and I met him when he visited us at the University of Saskatchewan one very cold winter day. He was soon posted to work with Aden Meinel at Yerkes Observatory, where he was added to the faculty and became the leader of the group when Meinel departed to organize the Kitt Peak National Observatory. He himself moved there in 1962 as Associate Director for Space Science; the name of the division was later changed to Planetary Science. He recruited a strong group to work on planetary atmospheres and several group members played important roles in the Mariner 10, Pioneer Venus, Viking, Voyager and Galileo missions. He was elected to the National Academy of Sciences in 1965. As leader of the group he recruited at Kitt Peak, Joe earned the admiration and loyalty of us all. He strongly preferred doing science to his administrative tasks, but he was still effective at the latter. He was considerably bothered that his superiors, especially the managing boards with which he had to deal, did not always meet his high standards.

  20. Shot noise displaying simultaneously the Noah and Joseph effects

    Science.gov (United States)

    Eliazar, Iddo; Klafter, Joseph

    2007-03-01

    Shot noise processes displaying the Noah effect are of infinite variance. Hence the measurement of the correlation structure of such processes—indicating whether the Joseph effect is displayed as well—cannot be conducted via their autocovariance functions (which are undefined). To circumvent this problem, a Poisson-based analysis applicable to shot noise processes with infinite variance, as well as to shot noise processes with divergent noise levels, is developed. A Poissonian autocovariance function, which characterizes the process-distribution of general shot noise processes, is introduced. In particular, this function governs and quantifies the processes’ stationary structure (amplitudal behavior) and correlation structure (temporal behavior). The “Poissonian methodology” developed enables a precise quantitative analysis of shot noise processes displaying simultaneously the Noah and Joseph effects.

MJD is an autosomal dominant neurodegenerative disorder of late onset, involving predominantly the cerebellar, pyramidal, extrapyramidal, motor neuron and oculomotor systems; although sharing features with other SCAs, the identification of minor, but more specific signs, facilitates its differential diagnosis. MJD presents strong phenotypic heterogeneity...

  4. Expansion at Olympic Dam

    International Nuclear Information System (INIS)

    The Olympic Dam orebody is the 6th largest copper and the single largest uranium orebody in the world. Mine production commenced in June 1988, at an annual production rate of around 45,000 tonnes of copper and 1,000 tonnes of uranium. Western Mining Corporation announced in 1996 a proposed $1.25 billion expansion of the Olympic Dam operation to raise the annual production capacity of the mine to 200,000 tonnes of copper, approximately 3,700 tonnes of uranium, 75,000 ounces of gold and 950,000 ounces of silver by 2001. Further optimisation work has identified a faster track expansion route, with an increase in the capital cost to $1.487 billion but improved investment outcome, a new target completion date of end 1999, and a new uranium output of 4,600 tonnes per annum from that date

  5. Dam spills and fishes

    International Nuclear Information System (INIS)

    This short paper reports the main topics discussed during the two days of the annual colloquium of the Hydro-ecology Committee of EdF. The first day was devoted to the presentation of the joint works carried out by EdF, the Paul-Sabatier University (Toulouse), the Provence St-Charles University (Marseille), the ENSAT (Toulouse) and the CEMAGREF (Lyon and Aix-en-Provence) about the environmental impact of dam spills on the aquatic flora and fauna downstream. A synthesis and recommendations were presented for the selection and characterization of future sites. The second day was devoted to the hydro-ecology study of the dam reservoir of Petit-Saut (French Guyana): water reoxygenation, quality evolution, organic matter, plankton, invertebrates and fishes. The 134 French dams concerned by water spills have been classified according to the frequency of spills, the variations of flow rates created, and their impacts on fishing, walking, irrigation, industry, drinking water, navigation, bathing. Particular studies on different sites have demonstrated the complexity of the phenomena involved concerning the impact on the ecosystems and the water quality. (J.S.)

  7. 1000 dams down and counting

    Science.gov (United States)

    O'Connor, James E.; Duda, Jeff J.; Grant, Gordon E.

    2015-01-01

    Forty years ago, the demolition of large dams was mostly fiction, notably plotted in Edward Abbey's novel The Monkey Wrench Gang. Its 1975 publication roughly coincided with the end of large-dam construction in the United States. Since then, dams have been taken down in increasing numbers as they have filled with sediment, become unsafe or inefficient, or otherwise outlived their usefulness (1) (see the figure, panel A). Last year's removals of the 64-m-high Glines Canyon Dam and the 32-m-high Elwha Dam in northwestern Washington State were among the largest yet, releasing over 10 million cubic meters of stored sediment. Published studies conducted in conjunction with about 100 U.S. dam removals and at least 26 removals outside the United States are now providing detailed insights into how rivers respond (2, 3).

  20. Damming evidence : Canada and the World Commission on Dams

    Energy Technology Data Exchange (ETDEWEB)

    Vert, P.; Parkinson, B.

    2003-06-01

    Large hydroelectric projects have been met with strong resistance from affected communities, particularly indigenous groups who have been displaced from their flooded communities following the damming of a river. The World Commission on Dams (WCD) was formed in 1998 to review the effectiveness of large dams and develop internationally acceptable guidelines and standards for large dams or hydro energy projects. The Canadian government, through the Canadian International Development Agency, was one of many governments to fund the WCD. However, the authors argue that despite the financial support, the Canadian government was absent from any effort to follow-up on the recommendations of the WCD. The seven strategic priorities in the decision making process include: (1) gaining public acceptance, (2) comprehensive option assessment of water, energy, food and development needs, (3) addressing existing dams to improve the benefits that can be derived from them, (4) sustaining livelihoods, (5) recognizing the entitlements and sharing benefits, (6) ensuring compliance, and (7) sharing rivers for peace, development and security. This report offers a means to assess planned or existing dams and presents a set of guidelines for good practices linked to the seven strategic priorities. Ten case studies from around the world were presented, including the Three Gorges Dam in China. 154 refs., 3 figs., 3 appendices.

    2001-05-01

    The present situation of waste- and tailings dams in Finland has been determined in this study including the structural safety and environmental impacts caused by dam functioning and failure. The collection of dam safety information was done with the help of the dam safety files and the technical visits on the dam sites. In addition the questionings were send to the dam owners. All together 61 waste dams and 12 tailings dams were investigated in the project. The realization of dam safety has been evaluated by dam structures and by meeting the requirements for the dams. The impacts on health and the environment have been evaluated during the dam functioning and failure. Furthermore the dam safety realization has been evaluated by occurred problems, the dam monitoring and the documents relevant to dam safety. On account of the project results the recommendations have been made in order to improve dam safety. In the future the dam failures can be avoided if (1) the geotechnical and other instructions for the dams are obeyed in the dam design and construction and (2) the operation, the maintenance and the monitoring of the dams will follow the Dam Safety Code of Practice.

    2010-07-01

    This presentation discussed Canadian and international initiatives for improving dam safety and described some of the drivers for the development of new Canadian Dam Association (CDA) public safety guidelines for dams. The CDA guidelines were divided into the following 3 principal sections: (1) managed system elements, (2) risk assessment and management, and (3) technical bulletins. Public and media responses to the drownings have called for improved safety guidelines. While the public remains unaware of the hazards of dams, public interaction with dams is increasing as a result of interest in extreme sports and perceived rights of access. Guidelines are needed for dam owners in order to provide due diligence. Various organizations in Canada are preparing technical and public safety dam guidelines. CDA guidelines have also been prepared for signage, booms and buoys, and audible and visual alerts bulletins. Working groups are also discussing recommended practices for spill procedures, spillways and the role of professional engineers in ensuring public safety. Methods of assessing risk were also reviewed. Managed system elements for risk assessment and public interactions were also discussed, and stepped control measures were presented. tabs., figs.

    Despite recent studies of chemistry courses and of academic research at the beginning of the eighteenth century, the perception of chemistry in the French Enlightenment has often been overshadowed by Lavoisier's works. This article proposes three specific case studies selected from Pierre Joseph Macquer's (1718-84) rich career to show the continuous evolution of chemistry throughout the century: medicinal chemistry through the application of the Comte de La Garaye's metallic salt solutions, the emergence of industrial chemistry through a few of Macquer's evaluations at the Bureau du Commerce, and finally communal academic research through the experiments on diamonds using Tschirnhaus's lens. These examples attempt to illustrate the innovative, creative, dynamic, multicultural, and multifaceted chemistry of the Enlightenment.

    2013-12-01

    John Fitzgerald Kennedy famously said, "One man can make a difference and every man should try."1 Joseph Rotblat (1908-2005) was the quintessence of Kennedy's conviction. He was the only scientist who left Los Alamos after it transpired that the atomic bomb being developed there was intended for use against adversaries other than Nazi Germany. I explore Rotblat's early research in Warsaw and Liverpool, which established his reputation as a highly capable experimental physicist, and which led him to join the Manhattan Project at Los Alamos in 1944. I examine his motivation for resigning from the project in 1945, and the unwillingness of his fellow scientists to follow suit, which draws attention to the continuing discourse on the responsibility of scientists for the consequences of their research.

    2010-07-01

    An understanding of the effect of earthquakes is necessary to the design of safe dams. A wide number of methods are currently used or being developed for analysing the dynamic slop stability of embankments/dams. This paper investigated the effects of the dynamic aspects (natural period, amplifications and intensity of seismic loading) in the analysis of small dams. A procedure was developed to evaluate the performance of pseudo-static analyses by comparison with fully dynamic analyses. Static, pseudo-static, and dynamic analyses were performed using finite elements and Mohr-Coulomb shear strength criteria. The overall safety factor (FS) was compared using the reduction factor concept. The study worked on two examples of small dams located at moderate and violent seismic regions in the province of Quebec. These examples illustrated the difference between pseudo-static and dynamic analyses. The study also investigated the values of the kh coefficient for Eastern Canada seismicity.

    There is growing interest to measure strain in many civil structures such as dams, bridges and tunnels. Optical fibre sensors are increasingly used to measure both temperature and, strain in such constructions. Essential development of this application for dams has been made previously by Sensornet and HydroResearch, within three research projects funded by Elforsk AB. In September 2004, the first distributed measurement of strain in an embankment dam was undertaken using the Sensornet DTSS. The system allows the strain and temperature to be measured simultaneously and independently at all points along the fibre. The measurement was carried out at Vattenfall Vattenkraft's Ajaure dam in Sweden. The aim was to compare the measurements taken during September, at full reservoir level, with measurements to be taken at low reservoir level in May 2005. The measured difference of strain between the two measurements is small, indicating no significant localized movement of the dam. These initial measurements demonstrate the potential of distributed strain measurements. Whilst undertaking strain measurement at Ajaure, a series of tests were also performed to demonstrate the ability of the DTSS to determine the size of localized deflection in the dam which could be detected by distributed strain measurements. Similar tests were also repeated in the Sensornet Laboratory. Those tests have demonstrated that a deflection of the dam by just 5 mm will be detectable. The current sensitivity of the system is suitable for detecting very small localized changes of the dam structure. However, the sensitivity is set to improve with further development, providing enhanced temperature correction and hence much increased strain accuracy. Distributed optical sensing will be an essential tool for dam monitoring, providing location specific information which has not been available before. The distributed technology provides an excellent complement to conventional inclinometers. Further

  7. Floods from tailings dam failures.

    2008-06-15

    This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is released, and this outflow volume is difficult to estimate prior the incident. In this study, tailings' volume stored at the time of failure was shown to have a good correlation (r2=0.86) with the tailings outflow volume, and the volume of spilled tailings was correlated with its run-out distance (r2=0.57). An envelope curve was drawn encompassing the majority of data points indicating the potential maximum downstream distance affected by a tailings' spill. The application of the described regression equations for prediction purposes needs to be treated with caution and with support of on-site measurement and observations. However, they may provide a universal baseline approximation on tailing outflow characteristics (even if detailed dam information is unavailable), which is of a great importance for risk analysis purposes.

  9. Electrical Enlightenment: Joseph Priestley's Historical and Experimental Studies of Electricity

    Science.gov (United States)

    Boantza, Victor

    Joseph Priestley (1733-1804) was one of the most controversial public figures of the eighteenth century. A true Enlightenment polymath, he wrote more than two hundred books, pamphlets, sermons, and essays on subjects ranging from science to politics and from metaphysics to theology. He was a religious dissenter, political radical, vocal supporter of the French Revolution, and lifelong defender of the losing side in the Chemical Revolution. Priestley is best known for having ``discovered'' oxygen in the 1770s and for his lasting contributions to pneumatic chemistry. Yet his first scientific fascination, while teaching at Warrington Academy, was electricity--one of the greatest scientific fads of the Enlightenment. Priestley's work on electricity, both historical and experimental, culminated in his History and Present State of Electricity (1767), which became a standard textbook on the subject for nearly a century, and went through numerous editions and translations. Situating Priestley's electrical investigations against the background of eighteenth-century ideals of scientific theory and practice, especially concerning physics, experimental philosophy, and natural history, illuminates the relations between science, society, and epistemology in the Enlightenment.

  10. Joseph Barcroft's studies of high-altitude physiology.

    West, John B

    2013-10-15

    Joseph Barcroft (1872-1947) was an eminent British physiologist who made contributions to many areas. Some of his studies at high altitude and related topics are reviewed here. In a remarkable experiment he spent 6 days in a small sealed room while the oxygen concentration of the air gradually fell, simulating an ascent to an altitude of nearly 5,500 m. The study was prompted by earlier reports by J. S. Haldane that the lung secreted oxygen at high altitude. Barcroft tested this by having blood removed from an exposed radial artery during both rest and exercise. No evidence for oxygen secretion was found, and the combination of 6 days incarceration and the loss of an artery was heroic. To obtain more data, Barcroft organized an expedition to Cerro de Pasco, Peru, altitude 4,300 m, that included investigators from both Cambridge, UK and Harvard. Again oxygen secretion was ruled out. The protocol included neuropsychometric measurements, and Barcroft famously concluded that all dwellers at high altitude are persons of impaired physical and mental powers, an assertion that has been hotly debated. Another colorful experiment in a low-pressure chamber involved reducing the pressure below that at the summit of Mt. Everest but giving the subjects 100% oxygen to breathe while exercising as a climber would on Everest. The conclusion was that it would be possible to reach the summit while breathing 100% oxygen. Barcroft was exceptional for his self-experimentation under hazardous conditions.

    2012-09-01

    This paper analyses the understandings of Daoist alchemy and Chinese sexuality of Joseph Needham and his friend and correspondent, the Chinese-Swedish writer Jolan Chang (Chang Chung-lan, 1917-2002). Using the extensive correspondence between the two men, as well as Needham's files on "inner alchemy" deposited at the Needham Research Institute, the paper begins with a partial reconstruction of a 1977 symposium, chaired by Needham, to promote Chang's new book, The Tao of Love and Sex: The Ancient Chinese Way to Ecstasy. Needham and Chang's visions of Chinese sex are then read against excerpts from Science and Civilisation in China, specifically Volume V: Chemistry and Chemical Technology, Part 5: Spagyrical Discovery and Invention: Physiological Alchemy (1983). Three inter-related aspects are explored. First, reading Science and Civilisation in China against materials in the Needham archives offers crucial hints to Needham's historiography and historical practice. Second, the way that Daoist regimens came to be actively reconstructed and repackaged as practices concerned with the enhancement of sexual pleasure and intensity. Third, the investigation of the networks and circulations of assumptions, visions, fantasies about "China". PMID:22652507

    Full Text Available During the past decade a few artists and even fewer entomologists discovered flatbed scanning technology, using extreme resolution graphical arts scanners for acquiring high magnification digital images of plants, animals and inanimate objects. They are not just for trip receipts anymore. The special attributes of certain scanners, to image thick objects is discussed along with the technical features of the scanners including magnification, color depth and shadow detail. The work of pioneering scanner artist, Joseph Scheer from New York’s Alfred University is highlighted. Representative flatbed-scanned images of moths are illustrated along with techniques to produce them. Collecting and preparing moths, and other objects, for scanning are described. Highlights of the Fulbright sabbatical year of professor Scheer in Arizona and Sonora, Mexico are presented, along with comments on moths in science, folklore, art and pop culture. The use of flatbed scanners is offered as a relatively new method for visualizing small objects while acquiring large files for creating archival inkjet prints for display and sale.

  14. Franz Joseph Gall and music: the faculty and the bump.

    2015-01-01

    The traditional story maintains that Franz Joseph Gall's (1758-1828) scientific program began with his observations of schoolmates with bulging eyes and good verbal memories. But his search to understand human nature, in particular individual differences in capacities, passions, and tendencies, can also be traced to other important observations, one being of a young girl with an exceptional talent for music. Rejecting contemporary notions of cognition, Gall concluded that behavior results from the interaction of a limited set of basic faculties, each with its own processes for perception and memory, each with its own territory in both cerebral or cerebellar cortices. Gall identified 27 faculties, one being the sense of tone relations or music. The description of the latter is identical in both his Anatomie et Physiologie and Sur les Fonctions du Cerveau et sur Celles de Chacune de ses Parties, where he provided positive and negative evidences and discussed findings from humans and lower animals, for the faculty. The localization of the cortical faculty for talented musicians, he explained, is demonstrated by a "bump" on each side of the skull just above the angle of the eye; hence, the lower forehead of musicians is broader or squarer than in other individuals. Additionally, differences between singing and nonsinging birds also correlate with cranial features. Gall even brought age, racial, and national differences into the picture. What he wrote about music reveals much about his science and creative thinking. PMID:25684283

    The Canadian Dam Association (CDA) committee is working with the Mining Association of Canada (MAC) tailings working group to ensure that technical issues related to the management and stewardship of tailings facilities are resolved. The Oilsands Dams Closure Group is now planning a workshop to discuss closure issues associated with the oilsands mining dams. The oilsands industry is currently constructing a number of large dams designed to contain contaminated solids and fluids. The dams will be required to last in perpetuity, and the closure group has been formed to consider what conditions will be required to maintain the dams in relation to regulatory oversight and inspections. The dams present an environmental challenge to the oilsands industry and may be of interest to many other mining industries who are required to retain dams forever.

  20. Simulation of Breach Outflow for Earthfill Dam

    International Nuclear Information System (INIS)

    Dams have been built for many reasons such as irrigation, hydropower, flood mitigation, and water supply to support development for the benefit of human. However, the huge amount of water stored behind the dam can seriously pose adverse impacts to the downstream community should it be released due to unwanted dam break event. To minimise the potential loss of lives and property damages, a workable Emergency Response Plan is required to be developed. As part of a responsible dam owner and operator, TNB initiated a study on dam breach modelling for Cameron Highlands Hydroelectric Scheme to simulate the potential dam breach for Jor Dam. Prediction of dam breach parameters using the empirical equations of Froehlich and Macdonal-Langridge-Monopolis formed the basis of the modelling, coupled with MIKE 11 software to obtain the breach outflow due to Probable Maximum Flood (PMF). This paper will therefore discuss the model setup, simulation procedure and comparison of the prediction with existing equations.

    Full Text Available Joseph Alois Schumpeter se hace acreedor a una muy merecida reputación en la Historia de la Teoría Económica por su concepción original de la dinámica del Sistema Capitalista. Básicamente, él le da al empresario el papel esencial del la innovación. Schumpeter distingue entre dos períodos dentro de la evolución del Capitalismo. El primero, el Capitalismo Competitivo en el que pocas firmas empezaron a mejorar innovaciones como resultado de las acciones de un empresario heroico. El segundo, el Capitalismo Confiable, un período dominado por muchas preocupaciones y monopolios en los quela propiedad podía cambiarse gracias a la posibilidad de comprar y vender acciones en los mercados financieros. Ambos períodos demandan los efectos de las innovaciones para crecer pero, de hecho, el fuerte papel de los empresarios. La visión Schumpeteriana es básicamente dinámica. Esta visión Encuentra el origen del cambio económico en el cambio técnico que sólo se posibilita mediante la aparición de innovaciones mejoradas por los empresarios. Esta interpretación original del sistema económico desarrollado por Schumpeter fue posible debido a las fuertes influencias de los economistas marginalistas austriacos, las relaciones de producción histórica desarrolladas por Marx, el modelo de equilibrio clásico de Walras y la explicación sociológica e institucional de Weber. En este artículo se presentan tanto la vida y el trabajo de Schumpeter como la explicación de la función del Sistema Capitalista.

A partir de la estrecha relación entre fe y ciencia incorpora en el diálogo con la bioética una necesaria dimensión teológica que ilumina y clarifica las respuestas a los verdaderos interrogantes que se plantean en las acciones bioéticas. Por un lado, la pregunta sobre el origen del hombre que es entendido como creación de Dios más allá de la reducción a un origen puramente biológico al que la postura pseudocientífica moderna lo quiere confinar. Por otro lado, la consiguiente cuestión, sobre la identidad del hombre, que es entendido como imagen de Dios, de donde brota su inviolable dignidad y la sacralidad de la vida humana, superando el materialismo cientificista. Y, por último, la pregunta sobre cómo tratar al “otro”, también al embrión, como consecuencia de su altísima dignidad, analizando las consecuencias éticas y jurídicas que se desprenden de su naturaleza y que se resumen en el deber de protección y respeto hacia el otro que el derecho debe garantizar y proteger frente a los abusos del más fuerte.

In 2005, an agreement was signed with IOP Publishing and the bustling production work of the in-house team moved abroad to Bristol, leaving just the Editor-in-Chief to man the ship at the Royal Swedish Academy of Sciences. In 2011, however, as Roger prepared to step down, submissions had reached astounding levels as is evident from figure 1: that year, almost 1500 manuscripts were received by Physica Scripta, now acknowledged to be amongst the fastest growing journals in IOP Publishing, when measured in these terms. The year on year increase stands at 20% and, once again, of the extensive range of topics covered, condensed matter physics had been identified as the subject area in most need of attention because the burden of reviewing had become too great for one editor to oversee alone. Thus, when I joined Physica Scripta in January of this year, securing new External Editors for this field was perceived to be the most urgent task. It is, therefore, with the greatest of pleasure that I am able to announce the arrival of two new editors for this section: Professors David Keen and Tapio Rantala.

    In 2007, a dam safety review of the Waterton Dam, located in southern Alberta, was completed. The dam safety review included an evaluation of the instrumentation installed at the dam, and what this instrumentation showed about the performance of the structure. This paper described the review of the instrumentation and dam performance, with particular emphasis on a set of hydraulic piezometers installed in the core at the deepest section of the dam. The paper presented background information on the dam and outlined the instrumentation and performance monitoring. Piezometer types were discussed. Performance data for the hydraulic and pneumatic piezometers in the dam core were summarized along with observations for piezometers in the foundation, upstream portion of the core and in the middle of the core. It was concluded that the review of dam performance has identified a horizontal zone of likely higher permeability within the dam, coinciding with the upper portion of the first construction season of the dam. 5 refs., 1 tab., 13 figs.

  17. Future directions of dam safety in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Verzeni, Gerard [Hydro Quebec, QC, (Canada)

    2010-07-01

    Gerard Verzeni, former director of the dam safety & environment at Hydro-Quebec introduced the future directions of dam safety in Canada. New and numerous challenges are emerging for the dam safety community. Measurable effects of climate changes illustrate that hydraulic forecasts would change drastically. Loads with times and amplitudes which are different from the actual knowledge will apply on dams. The development of new types of dams using recent technologies raises several issues, for example the longevity of such installations. The installations are becoming old and soon will require complete renovation and update for regulation and standards compliance. Concrete dams already need efforts and investment to maintain then in a safe state. Various factors will influence these challenges such as human resources in the dam safe community. In these conditions, it is important that organizations like CDA play an important role in providing support and reference and in being a driver for the whole industry.

    editor signals change and in turn this induces in some people expectation, hope of improvement and maybe radical revolution. Others cower and hope for stability, continuation of the same and as little outward sign of change as possible. So I should like to signal that I hope to satisfy both camps. The Editor-in-Chief is primarily a guardian of the journal and should change nothing that does not need changing. Maintaining a standard at the same level is a valuable achievement in itself. This is no different from taking on any other leadership role such as in a team or department. One has to lead by consensus and with respect for the position. Conversely there are things I would like to see improved (otherwise I should not have been hired) and I commit to attempting these but in a spirit of cooperation with the Board, the publisher (IOP), IPEM and the readership. Any other approach would be doomed anyway. So, what would I like to see changed? Dare I say anything too strongly upfront? Like Alun six years ago I would like there to be more debate via correspondence but this depends on the readers to do more writing along these lines. Personally I feel PMB, like many journals, has developed to the point where most readers sadly can understand only a small fraction of its contents. I have talked to older readers who said they regularly used to read all or half of the journal. Now many of us can manage only the papers in our specialty. Yet this is somewhat inevitable as medical physics has progressed from a fledgling science to the vast activity it is today, topics have become deeply complicated and we cannot and should not reverse the clock. To address this, I would like to see authors provide some form of `intelligible lay-scientific summary' of their paper as a condition of its publication. I think readers would then enjoy reading all, not just some, of these and maybe become attracted to other areas than the ones in which they currently work. I would like to see the

    Water management operations operates and maintains over 200 water management structures throughout Alberta. It includes around 30 extreme consequence, very high consequence and high consequence dams according to the Canadian Dam Association's (CDA) dam safety guidelines 2007. The safety of these structures is very important for the water management operations. This paper presented dam safety practise at water management operations dams. A historic perspective review of dam safety in Alberta was made. A framework of plant-implement-review-improve-report was developed and is currently used by the infrastructure support dam safety (ISDS) engineers. This dam safety work priority framework encourages an integrated decision making process and gives the dam safety team a tool for using and sharing information. This project made recommendations to rectify deficiencies, including with respect to priorities and timeframes, which are based on the severity of the issue, risk assessment and the consequences of failure.

    Nearly 30 people have drowned in dam-related incidents over the last 10 years in Canada. The Canadian public is now calling for improved safety guidelines. Public interaction with dams is increasing as a result of interest in extreme sports and perceived rights of access. However, many members of the public are not aware of the dangers posed by dams. This workshop provided a forum to discuss proposals for a draft publication of the Canadian Dam Association (CDA) guidelines for public safety and security around dams. Issues related to current legislation and liability were discussed. Methods of increasing public awareness of the hazards posed by dams included increased signage in dam locations, the use of audible and visual alert systems, and the use of booms and buoys. The responsibilities of dam owners in ensuring the safety of dams were also discussed. The conference featured 5 presentations, of which 2 have been catalogued separately for inclusion in this database. tabs., figs.

O paciente foi atendido no Setor de Fonoaudiologia do Serviço de Fisiatria do Hospital de Clínicas de Porto Alegre. Especificamente quanto à fala e seus processos, observou-se quadro disártrico predominantemente atáxico, que piorou com a evolução da doença, passando de leve para severo. Estes resultados permitiram a conclusão de que as alterações tornam-se significativas na fala do portador de doença de Machado-Joseph, associadas ao comprometimento da respiração, articulação, fonação e ressonância. Concluiu-se também quanto à importância do tratamento fonoaudiológico na doença de Machado-Joseph, sugerindo-se novos estudos, com número maior de indivíduos, sejam realizados, a fim de melhor caracterizar as alterações de fala observadas neste estudo.The aim of this study was to describe the essential speech aspects of Machado-Joseph disease in a male patient with this diagnosis, selected among others with the same disease that received treatment at the Speech-Language Pathology and Audiology department of Hospital de Clínicas de Porto Alegre (Brazil. Regarding the speech process, it was observed ataxic dysarthria, which worsened from light to severe with the evolution of the disease. These results allowed the conclusion that speech alterations become more and more significant for Machado-Joseph patients, together with deficits in breathing, articulation, phonation and resonance. Finally, it was possible to suggest that Speech Pathology treatment is essential in Machado-Joseph disease, although more studies are necessary, with larger samples, in order to better characterize the speech alterations observed this study.

    The aim of the present study is to describe the serum concentrations of a broad spectrum of cytokines in symptomatic and asymptomatic carriers of Machado Joseph disease (SCA3/MJD) CAG expansions. Molecularly confirmed carriers and controls were studied. Age at onset, disease duration, and clinical scales Scale for the Assessment and Rating of Ataxia (SARA), Neurological Examination Score for Spinocerebellar Ataxias (NESSCA), SCA Functional Index (SCAFI), and Composite Cerebellar Functional Score (CCFS) were obtained from the symptomatic carriers. Serum was obtained from all individuals and a cytokine panel "consisted of" eotaxin, granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon (IFN)-α, IFN-γ, interleukin (IL)-1β, IL-1RA, IL-2, IL-2R, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-15, IL-17, interferon gamma-induced protein (IP)-10, monocyte chemoattractant protein (MCP)-1, monokine induced by gamma interferon (MIG), macrophage inflammatory protein (MIP)-a, MIP-b, regulated on activation, normal T cell expressed and secreted (RANTES) and tumor necrosis factor (TNF)-α was analyzed. In a subgroup of symptomatic carriers, the cytokine panel was repeated after 360 days. Cytokine distribution among groups was studied by discriminant analysis; changes in serum levels after 360 days were studied by generalized estimation equation. Sixty-six symptomatic carriers, 13 asymptomatic carriers, and 43 controls were studied. No differences in cytokine patterns were found between controls and carriers of the CAG expansions or between controls and symptomatic carriers only. In contrast, eotaxin concentrations were significantly higher in asymptomatic than in symptomatic carriers or in controls (p = 0.001, ANCOVA). Eotaxin did not correlate with age, disease duration, CAG expansion, NESSCA score, and SARA score. Among symptomatic carriers, eotaxin dropped after 360 days (p = 0.039, GEE).

    Full Text Available Abstract Machado-Joseph Disease (MJD, also known as spinocerebellar ataxia type 3 (SCA3, represents the most common form of SCA worldwide. MJD is an autosomal dominant neurodegenerative disorder of late onset, involving predominantly the cerebellar, pyramidal, extrapyramidal, motor neuron and oculomotor systems; although sharing features with other SCAs, the identification of minor, but more specific signs, facilitates its differential diagnosis. MJD presents strong phenotypic heterogeneity, which has justified the classification of patients into three main clinical types. Main pathological lesions are observed in the spinocerebellar system, as well as in the cerebellar dentate nucleus. MJD's causative mutation consists in an expansion of an unstable CAG tract in exon 10 of the ATXN3 gene, located at 14q32.1. Haplotype-based studies have suggested that two main founder mutations may explain the present global distribution of the disease; the ancestral haplotype is of Asian origin, and has an estimated age of around 5,800 years, while the second mutational event has occurred about 1,400 years ago. The ATXN3 gene encodes for ataxin-3, which is ubiquitously expressed in neuronal and non-neuronal tissues, and, among other functions, is thought to participate in cellular protein quality control pathways. Mutated ATXN3 alleles consensually present about 61 to 87 CAG repeats, resulting in an expanded polyglutamine tract in ataxin-3. This altered protein gains a neurotoxic function, through yet unclear mechanisms. Clinical variability of MJD is only partially explained by the size of the CAG tract, which leaves a residual variance that should be explained by still unknown additional factors. Several genetic tests are available for MJD, and Genetic Counseling Programs have been created to better assist the affected families, namely on what concerns the possibility of pre-symptomatic testing. The main goal of this review was to bring together updated

  6. EPRI dam safety workshop summary: Proceedings

    International Nuclear Information System (INIS)

    The Electric Power Research Institute (EPRI) has an extensive history of working with utilities, federal and state agencies, consultants, and other interests to conduct a number of workshops and studies to improve the safety of dams. Through these efforts, EPRI has developed a number of tools to assist dam owners, particularly EPRI members, in the evaluation and modification of dams. Although a considerable amount of progress has been made toward improving dam safety, there remain among the over 75,000 dams in the US a significant number of structures that require in-depth evaluation and possible modifications. At the same time, there are pressures from several directions to prioritize dam safety issues and find cost-effective solutions to problems because there seems to be an ever-decreasing amount of funds to address dam safety. In that regard, EPRI is sensitive to those cost considerations in a changing utility environment. Therefore, EPRI recently entered into discussions with utilities, regulatory agencies, federal agencies (dam owners), and others interested in dam safety issues. From those discussions, a number of research ideas were developed, which were distilled into three primary topics and several secondary topics of importance. The three primary areas of concern included: penstocks, tunnels, and gates; instrumentation and monitoring; and post-tensioned anchors. This report will provide a review of the workshop and insight on ideas for future dam safety R and D

Task B: Installation of an extensive green roof system on the Science Center at Saint Joseph's University for research, research-training and educational outreach activities. An experimental green roof system was designed and installed by an outside contractor (Roofmeadows) on the roof of the Science Center at Saint Joseph's University. The roof system includes four test plots, each with a different drainage system, instrumentation to monitor storm water retention, roof deck temperature, heat flux into and out of the building, rain fall, wind speed and direction, relative humidity and heat emission from the roof system. The vegetative roof was planted with 26 species of plants, distributed throughout the roof area, to assess species/variety growth and coverage characteristics, both in terms of the different drain layer systems, and in terms of the different exposures along the north to south axis of the building. Analysis of the drain layer performance, in terms of storm water retention, shows that the aggregate (stone) drainage layer system performed the best, with the moisture management mat system second, and the geotextile drain layer and reservoir sheet layer systems coming in last. This information is of value in the planning and design of vegetative roof systems since the different types of drainage layer systems have different installation costs and different weights. The different drainage layer systems also seem to be having an impact on plant growth and spread with the test plot with the reservoir sheet layer actually having the poorest plant coverage and plant spread of all areas of the roof studied. Plant growth performance analysis is ongoing, but significant differences have been observed in the third growing season ('13) along the north to south axis, with most species doing better towards the northern end of the roof (in

    Task A: Examination of the physiological, morphological, and reproductive responses of Panicum virgatum (switchgrass) cultivars identified as potential biofuel producing cultivars as well as naturally-occurring varieties of switchgrass to projected changes in climate for the central portion of the United States. This project was a multi-year project set in a field site located at the Konza Prairie Biological Station near Manhattan, KS USA. At the field site we planted switchgrass collected from regions in Kansas, Oklahoma, and Texas. After a year of establishment we implemented a set of two-year water treatments that examined the responses in physiology, growth and development of switchgrass to predicted changes in precipitation amount for the central United States. After this experiment was completed we performed a second set of experiments that examined the responses of switchgrass physiology, growth, and development to changes in precipitation frequency. We also included in this analysis how genome size of individuals influenced their responses to precipitation frequency changes. Generally, we found switchgrass to be unresponsive to realistic predictions of precipitation changes for the Central Plains of the United States. These studies have provided significant insight into how this important grassland species will respond to future climate change from both an ecological and applied biological perspective. Finally, we provided insight into the mechanism through which this species changes in the face of altered water availability by not supporting the hypothesis that the control of switchgrass responses to changes in precipitation is altered by genome size.

  11. BOOK REVIEW: Joseph Henry: The Rise of an American Scientist

    Science.gov (United States)

    Crawford, Elspeth

    1998-09-01

    Albert Moyer has clearly done his research into the events of Joseph Henry's life. The personal, professional, sociological and scientific aspects have been meticulously detailed throughout and the ordering, as in the chapter headings, is chronological, so that there is some element of each of these aspects in each chapter. This is unfortunately both the strength and the weakness of the biography, as the detail seemed to me to be the most remarkable characteristic of the writing. But, the bigger stories, or the themes, which might have been possible, seemed to get lost. Hence, I found this a book for those who are seriously interested in Joseph Henry; but for those whose interest might be more general, say having an interest in nineteenth century growth of scientific institutions, or wanting to understand the conceptual development of electromagnetism, there seemed to be too much which came from the Henry point of view, rather than locating Henry within his time and context. This is a remark about style, rather than omission of content, as the myriad of details in each paragraph certainly inform the reader about the context. For instance, some sociology of the USA in the nineteenth century could be inferred, say showing how a young man from a modest background might make his way into a professional life, but the information is so particularly a description of Henry's experience that one has to rely on prior knowledge or make assumptions in order to create a sociological perspective. That is, I now know, what happened to Henry, but I do not know if his case was in any sense typical or atypical. Similarly there is information about education in general at that time, and scientific education, research and its publication, as it applied to Henry. The relationships between science in the USA and in Europe have a place, and there is quite a bit of information about the institutions in which Henry worked, particularly Albany Academy, Princeton and the Smithsonian.

    Full Text Available Abstract Background The potential pathogenetic significance of mitochondrial DNA (mtDNA mutations in tumorigenesis is controversial. We hypothesized that benign tumorigenesis of a slowly replicating tissue like the human parathyroid might constitute an especially fertile ground on which a selective advantage conferred by mtDNA mutation could be manifested and might contribute to the oxyphilic phenotype observed in a subset of parathyroid tumors. Methods We sought acquired mitochondrial DNA mutations by sequencing the entire 16.6 kb mitochondrial genome of each of thirty sporadic parathyroid adenomas (18 chief cell and 12 oxyphil cell, eight independent, polyclonal, parathyroid primary chief cell hyperplasias plus corresponding normal control samples, five normal parathyroid glands, and one normal thyroid gland. Results Twenty-seven somatic mutations were identified in 15 of 30 (9 of 12 oxyphil adenomas, 6 of 18 chief cell parathyroid adenomas studied. No somatic mutations were observed in the hyperplastic parathyroid glands. Conclusion Features of the somatic mutations suggest that they may confer a selective advantage and contribute to the molecular pathogenesis of parathyroid adenomas. Importantly, the statistically significant differences in mutation prevalence in oxyphil vs. chief cell adenomas also suggest that mtDNA mutations may contribute to the oxyphil phenotype.

It was a time when modern means of communication offered new opportunities for the scientific community—for all scientists and engineers whether at universities, in industry or at other institutions—to access better quality information in a shorter time. This development helped us to be more efficient in our daily scientific work and to anticipate new trends faster than before. A flood of information was created by different search engines. A few online journals or journals published in emerging countries with a similar profile to MST appeared on the market. MST had to provide new answers in response to these developments. In 2002 I postulated two requirements to the journal. Firstly, the publisher has to be up to date. My impression over the years has been that IOPP is excellently organized. That has made it easier for the board members and all our reviewers to concentrate on the scientific aspects of our input to the journal. During all my visits to Bristol or my contacts with the IOPP staff I always met very professional and enthusiastic staff members. They have not only supported and encouraged the ideas and initiatives of the Editorial Board members, but they have also worked hard on establishing one of the most effective journal operations in the field of measurement science and technology. Many authors are well aware of this. Thus I am able to declare that the first requirement for a successful journal has been met. Secondly, the scientific level has to be high and the journal should attract readers from all over the world. This task was the responsibility of the Editorial Board members and of myself. Our strategy was on the one hand to ensure continuity in MST but on the other hand to be open to new trends and developments. Examples of these new aspects of the journal are fields like micro- and nanometrology, measurement techniques for

    In the literature, there is information regarding the first deformation and displacement measurements in dams that were conducted in 1920s Switzerland. Todays, deformation measurements in the dams have gained very different functions with improvements in both measurement equipment and evaluation of measurements. Deformation measurements and analysis are among the main topics studied by scientists who take interest in the engineering measurement sciences. The Working group of Deformation Measurements and Analysis, which was established under the International Federation of Surveyors (FIG), carries out its studies and activities with regard to this subject. At the end of the 1970s, the subject of the determination of fixed points in the deformation monitoring network was one of the main subjects extensively studied. Many theories arose from this inquiry, as different institutes came to differing conclusions. In 1978, a special commission with representatives of universities has been established within the FIG 6.1 working group; this commission worked on the issue of determining a general approach to geometric deformation analysis. The results gleaned from the commission were discussed at symposiums organized by the FIG. In accordance with these studies, scientists interested in the subject have begun to work on models that investigate cause and effect relations between the effects that cause deformation and deformation. As of the scientist who interest with the issue focused on different deformation methods, another special commission was established within the FIG engineering measurements commission in order to classify deformation models and study terminology. After studying this material for a long time, the official commission report was published in 2001. In this prepared report, studies have been carried out by considering the FIG Engineering Surveying Commission's report entitled, 'MODELS AND TERMINOLOGY FOR THE ANALYSIS OF GEODETIC MONITORING OBSERVATIONS

    In 2009, AMEC was retained by Nova Scotia Power Inc. (NSPI) to conduct a dam safety review of the dams that are part of the Black River Hydroelectric System. This paper presented the results of this dam classification exercise which was carried out for the Bear River hydroelectric system in Nova Scotia, based on the 2007 Canadian Dam Association (CDA) dam safety guidelines. Flood mapping and dam-break analysis were performed for events ranging from the 1:100 year to PMF flood events, including cascading events. These results were used to draw up a classification of the dams. Associated design criteria were then developed. Following the assessment of the dam sites, conclusions and recommendations were discussed. The recommendations were presented in terms of regular maintenance items and reconstruction items, which are now used by NSPI to determine the party responsible for undertaking the recommendation and for evaluation of the maintenance and reconstruction schedules.

    In The Logic of Life (1970), Francois Jacob (1920- ), Nobel Prize laureate in Physiology or Medicine (1965), proclaimed the end of vitalism based on the concept of life. More than two decades before this capital sentence condemning vitalism was pronounced, Georges Canguilhem (1904-1995), a French philosopher of medicine, already acknowledged that eighteenth-century vitalism was scientifically retrograde and politically reactionary or counter-revolutionary insofar as it was rooted in the animism of Georg Ernst Stahl (1660-1734). The negative preconception of the term 'vitalism' came to be established as an orthodox view, since Claude Bernard (1813-1878) unfairly criticized contemporary vitalism in order to propagate his idea of experimental medicine. An eminent evolutionary biologist like Ernst Mayr (1904-2005) still defended similar views in This is Biology (1997), arguing that if vitalists were decisive and convincing in their rejection of the Cartesian model (negative heuristics), however they were equally indecisive and unconvincing in their own explanatory endeavors (positive heuristics). Historically speaking, vitalists came to the forefront for their outstanding criticism of Cartesian mechanism and physicochemical reductionism, while their innovative concepts and theories were underestimated and received much less attention. Is it true that vitalism was merely a pseudo-science, representing a kind of romanticism or mysticism in biomedical science? Did vitalists lack any positive heuristics in their biomedical research? Above all, what was actually the so.called 'vitalism'? This paper aims to reveal the positive heuristics of vitalism defined by Paul.Joseph Barthez (1734-1806) who was the founder of the vitalist school of Montpellier.

    More than 87000 dams have been built in China,and about one third of them are risky projects.A number of high and ultra-high dams are being constructed in China's western region.The current dam construction practice tends to focus on socio-economic benefits and neglect the environment and ecology.Furthermore,periodic examinations are intended to ensure the structural safety of dams.This paper proposes a general evaluation principle for dam service.This principle stipulates that dam projects should have maximum socio-economic benefits and minimum negative effects on the environment and ecology.To satisfy the general principle of mutual harmony,socio-economic benefits,dam safety,environment,and ecology are analyzed,and the evaluation methods for dam service status are discussed.Then,a fusion algorithm of interlayer assessment is proposed on the basis of evidence theory and the fuzzy comprehensive analysis method.Finally,a comprehensive evaluation model is established.Example analysis shows that the proposed theories and methods can fulfill scientific assessment of the service status of dams.

    International Nuclear Information System (INIS)

    Most aspects of the pre-production phase of the Olympic Dam Project, from commencement of exploration in May 1975 through to commitment to development in December 1985 are documented here. The discovery by Western Mining Corporation Ltd of copper mineralisation on Roxby Downs Station in July 1975 has led to one of the more intensive base-metal exploration programmes undertaken in Australia. Comprehensive exploration, evaluation and feasibility studies between 1975 and 1985 have delineated a probable 450 million tonnes of higher grade ore containing 2.5% copper, 0.8 kg/t uranium oxide, 0.6 g/t gold and 6.0 g/t silver. The total resource is estimated at 2 billion tonnes containing 1.6% copper, 0.6 kg/t uranium oxide, 0.6 g/t gold and 3.5 g/t silver. At 31 December 1985, over 540 km of surface and underground drilling had been completed, comprising over 700 surface drillholes totalling 234 km of core and 218 km of open-hole drilling, and about 900 underground diamond-drillholes totalling 90 km. The Whenan Shaft had been sunk to 500 m and driving on three levels totalled almost 10 km. More than one million tonnes of ore and mullock were raised during development. A pilot treatment plant commissioned on site produced concentrates, matte and blister copper, and ammonium diuranate. Following a technical study of the Olympic Dam Project, completed in March 1985, and a subsequent economic feasibility study, it was announced on 11 June 1985 that the initial project was considered to be commercially viable. On 8 December 1985, the joint venturers, Western Mining Corporation Holdings Ltd (51%) and the BP Group (49%), announced their commitment to the Project. An appendix lists the important events that occurred between January 1986 and December 1987 in bringing Olympic Dam to the production state. 26 refs., 17 figs., 5 tabs., ills

  19. Fragility Analysis of Concrete Gravity Dams

    Science.gov (United States)

    Tekie, Paulos B.; Ellingwood, Bruce R.

    2002-09-01

    Concrete gravity dams are an important part ofthe nation's infrastructure. Many dams have been in service for over 50 years, during which time important advances in the methodologies for evaluation of natural phenomena hazards have caused the design-basis events to be revised upwards, in some cases significantly. Many existing dams fail to meet these revised safety criteria and structural rehabilitation to meet newly revised criteria may be costly and difficult. A probabilistic safety analysis (PSA) provides a rational safety assessment and decision-making tool managing the various sources of uncertainty that may impact dam performance. Fragility analysis, which depicts fl%e uncertainty in the safety margin above specified hazard levels, is a fundamental tool in a PSA. This study presents a methodology for developing fragilities of concrete gravity dams to assess their performance against hydrologic and seismic hazards. Models of varying degree of complexity and sophistication were considered and compared. The methodology is illustrated using the Bluestone Dam on the New River in West Virginia, which was designed in the late 1930's. The hydrologic fragilities showed that the Eluestone Dam is unlikely to become unstable at the revised probable maximum flood (PMF), but it is likely that there will be significant cracking at the heel ofthe dam. On the other hand, the seismic fragility analysis indicated that sliding is likely, if the dam were to be subjected to a maximum credible earthquake (MCE). Moreover, there will likely be tensile cracking at the neck of the dam at this level of seismic excitation. Probabilities of relatively severe limit states appear to be only marginally affected by extremely rare events (e.g. the PMF and MCE). Moreover, the risks posed by the extreme floods and earthquakes were not balanced for the Bluestone Dam, with seismic hazard posing a relatively higher risk.

  1. Transplantation of cerebellar neural stem cells improves motor coordination and neuropathology in Machado-Joseph disease mice.

    Science.gov (United States)

    Mendonça, Liliana S; Nóbrega, Clévio; Hirai, Hirokazu; Kaspar, Brian K; Pereira de Almeida, Luís

    2015-02-01

    Machado-Joseph disease is a neurodegenerative disease without effective treatment. Patients with Machado-Joseph disease exhibit significant motor impairments such as gait ataxia, associated with multiple neuropathological changes including mutant ATXN3 inclusions, marked neuronal loss and atrophy of the cerebellum. Thus, an effective treatment of symptomatic patients with Machado-Joseph disease may require cell replacement, which we investigated in this study. For this purpose, we injected cerebellar neural stem cells into the cerebellum of adult Machado-Joseph disease transgenic mice and assessed the effect on the neuropathology, neuroinflammation mediators and neurotrophic factor levels and motor coordination. We found that upon transplantation into the cerebellum of adult Machado-Joseph disease mice, cerebellar neural stem cells differentiate into neurons, astrocytes and oligodendrocytes. Importantly, cerebellar neural stem cell transplantation mediated a significant and robust alleviation of the motor behaviour impairments, which correlated with preservation from Machado-Joseph disease-associated neuropathology, namely reduction of Purkinje cell loss, reduction of cellular layer shrinkage and mutant ATXN3 aggregates. Additionally, a significant reduction of neuroinflammation and an increase of neurotrophic factors levels was observed, indicating that transplantation of cerebellar neural stem cells also triggers important neuroprotective effects. Thus, cerebellar neural stem cells have the potential to be used as a cell replacement and neuroprotective approach for Machado-Joseph disease therapy.

  7. McNary Dam, Ice Harbor Dam, and Lower Monumental Dam Smolt Monitoring Program; 1996 Annual Report.

    Energy Technology Data Exchange (ETDEWEB)

    Hillson, Todd; Lind, Sharon; Price, William (Washington Department of Fish and Wildlife, Olympia, WA)

    1997-07-01

    The Washington Department of Fish & Wildlife (WDFW) assumed responsibility for the Smolt Monitoring Program at McNary Dam on the Columbia River in 1990 and at the new juvenile collection facility at Lower Monumental Dam on the Snake River in 1993. In 1996, Smolt Monitoring Program activities also began at the new juvenile collection facility located at Ice Harbor Dam. This report summarizes the 1996 Smolt Monitoring work at all three sites. The work at Ice Harbor consisted of Gas Bubble Trauma (GBT) monitoring only. In general, the 1996 passage season at both the McNary and Lower Monumental sites can be characterized by reduced passage of juveniles through the collection systems due to elevated river flows and spill, and low (<1%) overall facility mortality rates most likely resulting from cooler water temperatures. In accordance with the National Marine Fisheries Service recommendations (NMFS, 1995) all spring migrants were bypassed at McNary Dam in 1996. Mechanical problems within the McNary collection system resulted in collection and sampling activities being delayed until April 18 at this site, while sampling and collection began on the scheduled starting date of April 1 at Lower Monumental Dam. Monitoring operations were conducted through December 14 at McNary Dam and through October 28 at Lower Monumental Dam. An ongoing transportation evaluation summer migrant marking program was conducted at McNary Dam in 1996 by the NMFS. This necessitated the sampling of 394,211 additional fish beyond the recommended sampling guidelines. All total, 509,237 and 31,219 juvenile salmonids were anesthetized and individually counted, examined for scale loss, injuries, and brands by WDFW Smolt Monitoring personnel in 1996 at McNary Dam and Lower Monumental Dam, respectively.

    McPhail, Gordon; MacMillan, Dave; Smith, Bert [KGS Group, Winnipeg, (Canada); Lacelle, Justin [SaskPower, Regina, (Canada)

    2010-07-01

    An initial dam safety review was performed in 2005 and identified a number of concerns; the most critical were insufficient spillway capacity and deficiencies in the condition of the existing spillways. This paper described the challenges faced by the upgrading operation on the 50 year old Boundary Dam spillway started in 2008. SaskPower retained the KGS Group to increase the design spillway capacity to 1200 m3/s and remedy observed defects. The construction project involved maintaining the reservoir at full supply level while the 20m long spillway chute and stilling basin below were completely replaced. The difficulties came from the need to complete each year's construction such that the spillway could potentially pass spring flood flows. This paper showed that the upgrade measures selected for implementation were developed through close dialogue between the owner and the designer, with valuable input provided by a panel of external experts as well as from contractors participating in the design process.

    It is a pleasure and an honour for me to be taking over as Editor-in-Chief of Measurement Science and Technology. MST is well known across research communities worldwide as a leading journal in which to publish new techniques and instrumentation. It has gained this enviable position largely because of the excellent guidance of its Editorial Board and dedicated staff at Institute of Physics Publishing over many years. I want to highlight in particular the contribution of the outgoing Editor Peter Hauptmann, and other Editors before him, in making the journal truly international. We thank Peter immensely for all his hard work in leading the journal, having exceptionally served two terms, each of five years. I come into the post of Editor at a very interesting and challenging time for research. The global recession is leading to cuts in research funding in many countries, researchers and their outputs are coming under closer scrutiny than ever before, and more is being expected of them. Journals play a critical role in monitoring and maintaining research standards, but we should be careful not to assume that journal Impact Factor is the sole measure of research quality. Although expediency may sometimes demand it, Impact Factor, as practitioners know, is subject dependent. One of the great things about science and technology for me is its level playing field. The key point is still innovation no matter where the work is done or where it is published. MST has a long pedigree of being the natural home of the highest quality papers from leading researchers wishing to report novel instrumentation and techniques. 2013 will mark the 90th anniversary of MST and we look forward to celebrating in style its sustained success. I recall with pride the first paper I published in Journal of Physics E: Scientific Instruments (as MST was previously titled) back in 1977. The paper reported the design and application of an early fluorescence lifetime spectrometer that I had constructed

  4. Adaptability to geological faulted foundation of Hardfill dam

    Institute of Scientific and Technical Information of China (English)

    Kun XIONG; Yunlong HE; Yunfeng PENG

    2008-01-01

    Hardfill dam is a new type of dam which has the advantages of low stress level and even stress distri-bution in a dam body, resulting in low demands to foun-dations. Based on 2D linear elastic and elasto-plastic calculations of gravity dam and Hardfill dam using finite element method (FEM), the stress distribution in a dam body and anti-sliding stabilization is analyzed on the geo-logical faulted foundations with weak weathered rock and soft interlayers. It is concluded that Hardfill dams have better adaptability to geological faulted foundations than gravity dams and is more secure and economically sound.

  5. Restoring Environmental Flows by Modifying Dam Operations

    Directory of Open Access Journals (Sweden)

    Gregory A. Thomas

    2007-06-01

    Full Text Available The construction of new dams has become one of the most controversial issues in global efforts to alleviate poverty, improve human health, and strengthen regional economies. Unfortunately, this controversy has overshadowed the tremendous opportunity that exists for modifying the operations of existing dams to recover many of the environmental and social benefits of healthy ecosystems that have been compromised by present modes of dam operation. The potential benefits of dam "re-operation" include recovery of fish, shellfish, and other wildlife populations valued both commercially and recreationally, including estuarine species; reactivation of the flood storage and water purification benefits that occur when floods are allowed to flow into floodplain forests and wetlands; regaining some semblance of the naturally dynamic balance between river erosion and sedimentation that shapes physical habitat complexity, and arresting problems associated with geomorphic imbalances; cultural and spiritual uses of rivers; and many other socially valued products and services. This paper describes an assessment framework that can be used to evaluate the benefits that might be restored through dam re-operation. Assessing the potential benefits of dam re-operation begins by characterizing the dam's effects on the river flow regime, and formulating hypotheses about the ecological and social benefits that might be restored by releasing water from the dam in a manner that more closely resembles natural flow patterns. These hypotheses can be tested by implementing a re-operation plan, tracking the response of the ecosystem, and continually refining dam operations through adaptive management. The paper highlights a number of land and water management strategies useful in implementing a dam re-operation plan, with reference to a variety of management contexts ranging from individual dams to cascades of dams along a river to regional energy grids. Because many of the

  6. Seismic response of uplifting concrete gravity dams

    International Nuclear Information System (INIS)

    The foundation interaction effects on the seismic response of dam-foundation systems have generally been studied using the linear elastic finite element models. In reality, the foundation can not develop effective tensile stresses to a significant degree along the interface. A two-dimensional finite element model, in which nonlinear gap elements are used at the dam-foundation interface to determine the uplift response of concrete gravity dams subjected to seismic loads, is presented. Time domain analyses were performed for a wide range of modelling assumptions such as dam height, interface uplift pressure, interface mesh density, and earthquake input motions, that were systematically varied to find their influence on the seismic response. The nonlinear interface behavior generally reduces the seismic response of dam-foundation systems acting as a seismic isolation mechanism, and may increase the safety against sliding by reducing the base shear transmitted to the foundation. 4 refs., 5 figs., 6 tabs

    Because of the catastrophic effects downstream of dam-break failure, more and more researchers around the world have been working on the study of dam-break flows to accurately forecast the downstream inundation mapping. With the rapid development of computer hardware and computing techniques, numerical study on dam-break flows has been a popular research subject. In the paper, the numerical methodologies used to solve the governing partial differential equations of dam-break flows are classified and summarized, and their characteristics and applications are discussed respectively. Furthermore, the fully-developed mathematical models developed in recent decades are reviewed, and also introduced the authors\\' on-going work. Finally, some possible future developments on modeling the dam-break flows and some solutions are presented and discussed. © 2011 IEEE.

  8. Do we need construct more dams?

    Science.gov (United States)

    Chen, J.; Shi, H.

    2013-12-01

    This paper reviews global dam development in association with the growths of global population, economy, and energy consumption in the past several decades, and also evaluates contributions of dam development to future world sustainable development. Eventually, this paper answers whether we need more dams in the future or not. The world population has rapidly increased from 1.6 billion in 1900, 2.5 billion in 1950, 6.1 billion in 2000, to 7.0 billion in 2011, and is projected to reach 9.5 billion in 2050; similarly, the world economy has dramatically expanded. To maintain socioeconomic development, the consumption of water, food and energy has increased rapidly as well. However, the total volume of available water resource over the world is limited, the food production largely depends on water supply, and the main energy sources are still oil, coal and gas at present, which are regarded as non-renewable resources. Accordingly, it is expected that we will face serious problems to deal with the challenges of water crisis, food security and energy shortage in the near future. In order to enhance the capability of regulating water resource, a great number of global dams (and related reservoirs) have been constructed in the last one hundred years; currently, almost all large rivers over the world have been regulated by dams. The reservoirs can supply sufficient water for irrigated land to ensure food production, and the associated hydropower stations can generate electricity. This article collects the dam data from the ICOLD (International Commission on Large Dams) and GRanD (Global Reservoir and Dam) databases, and some socioeconomic data, including population, economy, and consumptions of water, food and energy over the world. Analysis of these data reveals that global dam development has a great impact on the world sustainable development. Further, it is concluded that we need further dam development to maintain our future development.

  9. Seismic failure modes and seismic safety of Hardfill dam

    Institute of Scientific and Technical Information of China (English)

    Kun XIONG; Yong-hong WENG; Yun-long HE

    2013-01-01

    Based on microscopic damage theory and the finite element method, and using the Weibull distribution to characterize the random distribution of the mechanical properties of materials, the seismic response of a typical Hardfill dam was analyzed through numerical simulation during the earthquakes with intensities of 8 degrees and even greater. The seismic failure modes and failure mechanism of the dam were explored as well. Numerical results show that the Hardfill dam remains at a low stress level and undamaged or slightly damaged during an earthquake with an intensity of 8 degrees. During overload earthquakes, tensile cracks occur at the dam surfaces and extend to inside the dam body, and the upstream dam body experiences more serious damage than the downstream dam body. Therefore, under the seismic conditions, the failure pattern of the Hardfill dam is the tensile fracture of the upstream regions and the dam toe. Compared with traditional gravity dams, Hardfill dams have better seismic performance and greater seismic safety.

  10. The role of dams in development

    International Nuclear Information System (INIS)

    Although the amounts of water resources are enough for the entire world, the distribution of them in time and space shows uneven pattern. The water need is increasing with heavy industrial and agricultural requirements, while available water in the world remains as a fixed source. Economic growth, socio-cultural, and environmental developments are being realized following these changes. In order to achieve sustainable management of water resources, these changes have to be taken into consideration in water-related development projects. Demand for water is steadily increasing through out the world, even though the fresh water resources are limited and unevenly distributed, during the past three centuries, the amount of water withdrawn from fresh water resources has increased by a factor of 35, whereas world population by a factor 8. The engineering of dams, which provides regular water from reservoirs of dams to be used in case of demand pattern, is a vital part of the civilization. Dams have played a key rote in the development since the third millennium B C when the first great civilizations evolved on major rivers, such as Tigris-Euphrates, the Nile and the Indus. From these early times dams were built for flood control, water supply, irrigation and navigation. Dams also had been built to produce motive power and electricity since the industrial revolution. Development priorities changed, experience accumulated with the construction and operation of dams. Although the importance of water is well known in the human life and civilization around the world, still various groups argue that expected economic benefits are not being produced and that major environmental, economic and social costs are not being taken into account. By the end of 20th century, there were 45000 large dams in over 150 countries. According to the same classification there are 625 large dams in Turkey. All over the world, 50 % of the large dams were built mainly for irrigation. It is estimated

    International Nuclear Information System (INIS)

    Barriers are a major component of the satefy concept for the Gorleben repository. The construction and performance of dams are currently tested within the framework of a project carried out in the Asse salt mine. A measuring programme has been established to give evidence of the sealing capacities of a barrier consisting of an abatement, long-term sealing material, and a hydraulic sealing system. Tests are to be made to verify the barrier's performance for shorter of long time periods (up to about 500 years). The tests are assisted by computed models established for the project. The long-term safety aspects to be studied include such conditions as permeability changes due to mechanical impacts, circulation conditions at the roadside, and the serviceable life and efficiency of the sealing components.

  12. TYPOLOGY OF LARGE DAMS. A REVIEW

    Directory of Open Access Journals (Sweden)

    Gheorghe ROMANESCU

    2015-06-01

    Full Text Available The dams represent hydrotechnical constructions meant to ensure a judicious use of water resources. The international literature is extremely rich in data regarding the large dams on Earth. In this context, a hierarchy of the main dams is attempted and the role they play in the economic development of the regions they were built in is underlined. The largest dams are built on the big rivers in Asia, North America, South America and Africa. The reservoirs have multiple roles: electricity production, drinking or industrial water supply, irrigations, recreation, etc. High costs and land fragility do not allow the construction of dams in the places most affected by drought or flood. This is why they are usually built in mountainous areas, at great distance from the populated centres. On the Romanian territory, there are 246 large dams, built in the hydrographical basins of Siret, Olt, Arges, Somes, etc. The largest rivers on Earth, by discharge, (Amazon and Zair do not also include the largest dams because the landform and the type of flow have not allowed such constructions.

    In this paper, we show that the certain elaborations of the French sociologist Gariel Tarde may be traced throughout Schumpeter’s works. More specifically, we show that Joseph Schumpeter’s views were influenced by the French social philosopher and theoretician Gabriel Tarde who delivered a theory of Social Evolution based on Technological Change as its driving force, closely related to the profiteering function of the economy. Also, we demonstrate that Tarde’s approach has striking similar...

    Chemotherapy-induced peripheral neurotoxicity is a major problem because it represents the dose-limiting side effect of a significant number of antineoplastic drugs, such as vinca alkaloids. Hereditary neuropathies usually predispose to severe vincristine neurotoxicity. Here, we report the case of a 56-year-old man with Machado-Joseph disease, also known as spinocerebellar ataxia type 3, treated with a vinca alkaloid without exacerbation of neurological symptoms.

    The failure of the Tapo Canyon tailings dam was one of the most striking failures of an earth structure to result from the January 17, 1994 Northridge, California earthquake. The failure involved a 60-m-wide breach of a tailings dam with a maximum height of 24 m, and 60 and 90 m downstream displacements of two sections of the dam. The failure resulted from liquefaction of the impounded tailings and possibly of the embankment materials. A significant volume of liquefied tailings passed through...

    2012-04-01

    Full Text Available à partir de 1413, Jean Gerson se lance dans une véritable campagne de promotion en faveur de Joseph, l’époux de Marie, à un moment où celui-ci est très rarement considéré comme un saint, et intéresse peu les théologiens et les prédicateurs, à l’exception de quelques franciscains. Or, parmi les privilèges et les vertus que le chancelier attribue à Joseph, on est surpris de rencontrer l’idée d’une sanctification in utero, qui rappelle l’immaculée conception de Marie, pour laquelle Gerson s’était battu aux côtés de son maître Pierre d’Ailly. Cette affirmation se fait cependant avec prudence, sous la forme d’une idée à laquelle on peut « croire pieusement ». à l’occasion d’un sermon prononcé au concile de Constance, Gerson précise sa pensée en distinguant la Vierge, totalement préservée du péché originel, de Joseph sanctifié dans le sein de sa mère. La logique est celle d’une comparaison avec Jean-Baptiste, que l’on considère consacré in utero au moment de la Visitation. Comme Gerson tente d’affirmer la supériorité de Joseph sur le Baptiste, il cherche à lui attribuer une grâce au moins comparable. L’enjeu est la reconnaissance de la sainteté de Joseph, dont la définition est délicate puisqu’il est sans doute mort avant la Passion et qu’il ne peut être reconnu comme un martyr.Même si la formulation gersonienne reste très originale, son idée a sans doute été mûrie au contact d’autres admirateurs de l’époux de la Vierge, tels Pierre d’Ailly ou le célestin Pierre Pocquet. Elle s’appuie également sur des sources liturgiques orientales plus délicates à identifier. Néanmoins, sa proposition ne connaîtra pas un grand succès : reprise par quelques auteurs au cours des xve et xvie siècles, elle est finalement explicitement rejetée lorsque s’affirme le culte de Joseph et que sa sainteté n’est plus contestée.Elle reste le témoignage d’un moment

    If mine waste materials are stored in dams, the dams are referred to as tailings dams. Tailings dam failures can lead to massive destruction in nearby areas because of the large amount of water and slurry tailings stored in the dams. Tailings dams are large constructions which therefore endure great stresses. If the stresses become higher than what the materials of the dam can tolerate there is a risk that the embankment will collapse. This master thesis is the result of a collaboration betwe...

    2014-06-01

    Based on a Chinese national high arch dam located in a meizoseismal region, a nonlinear numerical analysis model of the damage and failure process of a dam-foundation system is established by employing a 3-D deformable distinct element code (3DEC) and its re-development functions. The proposed analysis model considers the dam-foundation-reservoir coupling effect, influence of nonlinear contact in the opening and closing of the dam seam surface and abutment rock joints during strong earthquakes, and radiation damping of far field energy dissipation according to the actual workability state of an arch dam. A safety assessment method and safety evaluation criteria is developed to better understand the arch dam system disaster process from local damage to ultimate failure. The dynamic characteristics, disaster mechanism, limit bearing capacity and the entire failure process of a high arch dam under a strong earthquake are then analyzed. Further, the seismic safety of the arch dam is evaluated according to the proposed evaluation criteria and safety assessment method. As a result, some useful conclusions are obtained for some aspects of the disaster mechanism and failure process of an arch dam. The analysis method and conclusions may be useful in engineering practice.

    The Canadian Dam Association (CDA) issued dam safety guidelines in 1995. Since then, the guidelines have been widely used in Canada and elsewhere, and have become a standard in Canada where regulations do not exist. This workshop was a forum to begin the process of creating a draft publication of a new version of the CDA Dam Safety Guidelines that will incorporate issues of public safety and security around dams. The objectives of the workshop were to learn the current state of industry practice in terms of public safety around dams; input to the draft CDA guidelines; discuss the principles which will govern preparation of the guidelines; share experiences in public safety around dams; hear regulator's views on the issue of public safety around dams; and establish areas for further research and development. The presentations discussed a broad range of topics, including recent waterway incidents around dams; industry initiatives and benchmarking; occupier's liability and trespass; high risk behaviour near dams and power stations; risk assessment process for public safety; and the Federal Energy Regulatory Commission's (FERC's) hydropower public safety program. The workshop featured 18 presentations, of which 13 have been catalogued separately for inclusion in this database. tabs., figs.

    Kühnel, Markus

    In Thuringia the second highest dam of Germany is under construction (figure 1). The new Leibis/Lichte dam is a 370 m long and 102.5 m high gravity dam of concrete with straight axis. With the completion of the Leibis/Lichte dam in 2005 more than 300.000 inhabitants of the Eastern Regions of Thuringia will be supplied with high quality drinking water. The foundation rocks at the dam site are exclusively greyish-blue argillaceous schist, silt schist and cleaved fine sandstones from the Ordovician period (phycode schist). The main joint system consists of three differently orientated joints. Geomechanically of main interest is the shallow dipping bedding, especially in the left abutment because of its downhill dip. The other joints show a generally steep dip. Wide extending faults with thick mylonites or fractured zones, which could influence the foundation of the dam, do not exist within the dam site. The engineering geological field mapping of the foundation surface confirms the rock mass parameters. The excavation works are carried out in four different stages to avoid loosening of the foundation rock. Great care is taken to assure that the foundation rock is protected against weathering. Based on the results of preliminary investigations the foundation level was planned in a depth of 4 to14 m. The abutments of the dam correspond to the expectations. Predominantly the argillaceous rock shows a low permeability. The permeability is exclusively linked to faults respectively few large joints. In order to prevent seepage and to reduce the uplift pressure, a grout curtain in two rows is arranged with a depth of 5 to 44 metres.

    There are 1300 licensed dams in Alberta. Most were designed and constructed between the late 1940s and the early 1960s. As a rule, compacted earthfill in preglacial and interglacial valleys in southern Alberta was used to construct all dams of moderate height. At these dam sites, the foundations are of valley infill alluvial soils underlain by weak rocks. The best prevailing engineering practices at the time were used to design these dams. It included drilling, soil testing prior to and during construction, and some stability analyses. Despite these measures, a number of the dams built on soft clays suffered significant deformations and cracking of the embankment during construction. A re-examination of the stability of some of the older dams in Alberta, owned by the provincial department of the Environment, was undertaken six years ago using currently accepted design practices. Allowance was made in the new analyses for the presence of shear zones and fissures in the foundation soils, as well as softening caused by wetting. Despite many years of apparently satisfactory service, Factors of Safety that were marginal or deficient were discovered at many dams. The authors presented case histories of three older dams (North and South McGregor, and North Ridge, all located in southern Alberta) for which the long term Factors of Safety were marginal under normal loading. A number of criteria, such as deformation, stress strain curves of foundation materials and the consequence of failure were taken into consideration in assessing and confirming the requirement for repair before any structural modifications were undertaken. Some of the repairs that were carried out were also briefly described. 12 refs., 4 tabs., 5 figs.

    Walter Bouldin is one of several hydroelectric developments of Alabama Power Company. On February 10, 1975, an earth embankment section of Walter Bouldin Dam was breached, causing total evacuation of the forebay reservoir and rendering the 225-MW power plant inoperable. The Federal Power Commission instituted an investigation of the dam failure, and a report on the investigation was published in February 1976. Subsequently, an evidentiary hearing was held before an administrative law judge who issued his initial decision on August 19, 1976. The Commission, on April 21, 1977, issued its Opinion No. 795 in which it adopted the initial decision with modifications and terminated the investigation of failure of Walter Bouldin Dam. Opinion No. 795 directs the staff of the Bureau of Power to prepare, for the future guidance of the Commission, a report on the deficiencies which were found in its investigation, together with advice as to how such deficiencies have been and should be remedied. Also, it directs the staff of the Bureau of Power to address certain general recommendations included in the initial decision. This report was prepared in response to that directive and summaries information on the dam failure and its investigation; the evidentiary hearing; the judge's recommendations, the reconstruction of the Bouldin Dam; and the evalution and status of the Federal Energy Regulatory Commission Dam safety program.

  12. OVERVIEW OF DAM GULLY EROSION RESEARCH

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Traditionally gully erosion has been identified with the dissection of the landscape in agricultural settings but it is also recognized as a prevalent erosion feature in earthen dam auxiliary spillways and embankments. Flows through earthen spillways and over dam embankments, due to large rainfall events, have the potential to erode and breach the dam or spillway and result in catastrophic releases from the reservoir. The gully erosion process in an earthen spillway or on an embankment can be characterized by stages of initiation, development, and migration of a headcut. A headcut is defined as a near vertical drop at the upstream end of a gully. The rate of headcut migration is important in determining the breach potential of an earthen spillway and dam embankment. A research program is being conducted to examine the gully erosion processes of earthen dam auxiliary spillways and embankments. This paper describes: 1) the unique test facilities constructed to examine the dominant factors affecting the erosion of earthen spillways and embankments; 2) the observations of the erosion processes and results to date; and 3) the predictive relationships that have been developed for dam gully erosion research at the ARS Hydraulic Engineering Research Unit laboratory in Stillwater, OK.

  13. Expectations of immortality: dam safety management into the next millennium

    International Nuclear Information System (INIS)

    Topics concerning the problems associated with older and aging dams are considered including: what can be done to extent the lifetime of an old dam, the decision to decommission a dam based on a value judgment that the risk of maintaining the dam is too great for society's acceptance, the possibility of change in the level of risk tolerance with time in a technological environment, traditional surveillance methods used by dam owners in the Y2K situation, and the unreality of dam immortality. Trends and means for preserving older dams for their owner's purposes are outlined, as well as their lifetime compared to that of the downstream systems they serve. Despite the fact that we live in a throwaway society, dam owners cannot just leave their dam asset when they are through with using it. Someone has to maintain the dam, or ensure that it is safely decommissioned when the owner is finished with it. On a worldwide scale the available pool of experienced dam engineers is shrinking. This problem needs to be addressed by a shift towards operating and dam safety management skills based on a firm awareness of dam design principles. A shift in society's expectations has occurred such that dam designers and owners must now recognize the impact a dam can have both on its natural and social environments. Because of the increasing emphasis on paying attention to the impacts of people's activities on the planet, engineers more than anyone else must have a significant influence in that direction. 9 refs

  14. Game model of safety monitoring for arch dam deformation

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Arch dam deformation is comprehensively affected by water pressure,temperature,dam’s structural behavior and material properties as well as other factors.Among them the water pressure and temperature are external factors(source factors) that cause dam deformation,and dam’s structural behavior and material properties are the internal factors of deformation(resistance factors).The dam deformation is the result of the mutual game playing between source factors and resistance factors.Therefore,resistance factors of structure and materials that reflect resistance character of arch dam structure are introduced into the traditional model,where structure factor is embodied by the flexibility coefficient of dam body and the maximum dam height,and material property is embodied by the elastic modulus of dam.On the basis of analyzing the correlation between dam deformation and resistance factors,the game model of safety monitoring for arch dam deformation is put forward.

    The concept of asphalt as a waterproofing medium inside embankment dams was originally developed in Germany in the 1960s. More than 100 asphalt core rockfill (ACRD) dams have been completed or are under construction. They all have a strong record without any seepage problems or required maintenance. After using the glacial till as waterproofing material for its embankment dams for more than 50 years, Hydro-Quebec is now looking to develop new dam concepts, mainly for the zones where natural waterproofing materials do not exist. In order to do so, the company has decided to design and construct the Nemiscau-1 Dam as a prototype ACRD. This paper presented the detailed design criteria, technical specifications as well as some information concerning the construction of the dam such as asphalt mix design. The given dam site, geology and materials is well suited for a dam with an asphalt core and the chosen core thickness of minimum 400 mm was found to be appropriate, given the small net water head. The main reservoir levels as well as the characteristics of the dam were also listed. Information on the general construction of the dam was provided. It was concluded that the longitudinal profile of the rock excavation and concrete plinth must be optimized, with an optimum balance between the rock excavation, the volume and shape of the concrete plinth and finally, the placement of the asphalt core with the manual method. Several combinations of these 3 elements must be analyzed at the design stage and the most cost effective one should be applied on site. 5 tabs., 7 figs.

    The forecasting of extreme events is a highly topical, cross-disciplinary problem. One aspect which is potentially tractable even when the events themselves are stochastic is the probability of a “burst” of a given size and duration, defined as the area between a time series and a constant threshold. Many natural time series depart from the simplest, Brownian, case and in the 1960s Mandelbrot developed the use of fractals to describe these departures. In particular he proposed two kinds of fractal model to capture the way in which natural data is often persistent in time (his “Joseph effect”, common in hydrology and exemplified by fractional Brownian motion) and/or prone to heavy tailed jumps (the “Noah effect”, typical of economic index time series, for which he gave Levy flights as an examplar). Much of the earlier modelling, however, has emphasised one of the Noah and Joseph parameters (the tail exponent mu and one derived from the temporal behaviour such as power spectral beta) at the other one's expense. I will describe work [1] in which we applied a simple self-affine stable model-linear fractional stable motion (LFSM)-which unifies both effects to better describe natural data, in this case from space physics. I will show how we have resolved some contradictions seen in earlier work, where purely Joseph or Noah descriptions had been sought. I will also show recent work [2] using numerical simulations of LFSM and simple analytic scaling arguments to study the problem of the area between a fractional Levy model time series and a threshold.

    This paper reported on a joint research project between Laval University and Hydro-Quebec to study ice forces on dams in an effort to harmonize design criteria and develop mitigation strategies. This paper introduced the project and explored some of the preliminary results of the 2007-2008 field season. Ice displacement, ice stresses and ice forces on the LaGabelle dam were measured at several locations. The paper identified and discussed the complex relationships between data sets and discussed the spatial-temporal variability of the ice forces and its impact on design criteria. The project objective was to develop design criteria for ice forces on dams and to provide a scientific basis for interpreting and harmonizing existing recommended criteria. The methodology and site description were presented. It was concluded that the ice processes in a reservoir near a dam face subject to water fluctuations are quite complex. Therefore, in order to know the real average pressure on the dam, a significant amount of panels are required, having important implications for determining safe design values. 9 refs., 10 figs.

    Ice loads exerted on dams are not well understood. Measuring ice pressure is a challenge, especially when the ice environment is highly subject to creep. This paper discussed a program to evaluate ice load thrust on dams that was undertaken during the winter of 2007 to 2008 at La Gabelle and 2008 to 2009 at Beaumont and La Gabelle. The project involved measuring ice load thrust on the dam face in order to harmonize different design load criteria put forward by experts. The paper presented the preliminary results on the objectives of establishing maximum load levels and harmonizing ice load design criteria. Field program and instrumentation and the physical behaviour of ice were outlined. Ice pressure and ice load measurements were also discussed. It was concluded that the measurements near the dams yielded peak values of less than 150 kN/m, which was compatible with previous studies. Non-uniform distributions of the ice loads along the dam were observed, indicating that measurements at many points are needed in order to be meaningful. 10 refs.

    The Journal has published several articles critical of the World Bank and the International Monetary Fund. These articles have shown the damage caused by the neoliberal policies advocated by these agencies to the health and quality of life of the people in countries where such policies are carried out. Published here are excerpts of a speech given by Joseph Stiglitz, senior economist of the World Bank, in which he finally recognizes the damage these policies have caused in Russia, where life expectancy has fallen quite dramatically during the years of neoliberal reform. The question triggered by his speech is why the World Bank continues its neoliberal policies.

    This paper preseuts results of model tests for the landslide dam failure of a single dam and cascade dams in a sloping channel.The dams were designed to be regular trapezoid with fine sand.A new measuring method named the labeled line locating method was used to digitalize the captured instantaneous pictures.Under two differem inflow discharges,the morphological evolution and the flow patterns during one dam failure and the failure of cascade dams were investigated.The results indicate that when the inflow discharge is large,the deformation pattern of the downstream dam is similar to that of the upstream dam,and both dams are characterized with the overtopping scour throughout the dam failure process.When the inflow discharge is small,the upstream dam is scoured mainly through a sluice slot formed by the longitudinal incision,and the downstream dam is characterized with the overtopping scour.The data set presented in this paper can be used for the validation of numerical models and provide a reference for the flood risk management of cascade landslide dams.

    There is a need for research on upstream tailings dams to better understand the causes of past failures and to provide the tools capable of operating such facilities reliably and safely. This paper presented the development of a method for determining tailings dam stability. The study proposed the use of the point estimate method (PEM) as a tool to account for the inherent uncertainty in tailings impoundment. The PEM is an alternative approach for calculating the statistical moments of the limit state function. The proposed approach is applied on a cross-section of an upstream tailings dam to evaluate its performance during staged construction using a 2-D nonlinear coupled finite element model. The results illustrated the benefits of the proposed approach. This was the first time that the PEM was applied to a tailings impoundment using the hydro-mechanical, fully coupled transient finite element modelling technique.

    1998-01-01

    A flood-control dam was completed during 1979 on Bear Creek, a small tributary stream to the South Platte River in the Denver, Colorado, area. Before and after dam closure, repetitive surveys between 1977 and 1992 at five cross sections downstream of the dam documented changes in channel morphology. During this 15-year period, channel width increased slightly, but channel depth increased by more than 40 percent. Within the study reach, stream gradient decreased and median bed material sizes coarsened from sand in the pools and fine gravel on the riffle to a median coarse gravel throughout the reach. The most striking visual change was from a sparse growth of streamside grasses to a dense growth of riparian woody vegetation.

    The Maroon dam, built on the Maroon River in the Khoozestan province (southwest) of Iran, has a height of 176 metres and a 1.2 billion cubic metre reservoir. It is one of the largest embankment dams in Iran. A number of unpredicted inflows of water into tunnels and other underground openings occurred during the first impoundment of the Maroon dam. Impoundment was halted and the reservoir was emptied to correct the problem. This paper reviews the measures that were implemented during the remediation process, and presented an evaluation of the effectiveness of the process. The foundation treatment involved placing concrete in the caverns, constructing a concrete lining, and extending the grout curtain. The grouting procedure was also described. The overall effectiveness of the concrete work and grouting resulted in a reduction in leakage from 8.5 cubic metres per second to a more acceptable 10 litres per second. 8 figs.

  2. The big issue: environment and large dams

    1999-09-01

    Some of the environmental issues associated with large dams are discussed. Prior to commencement of construction of the Three Gorges dam in China in 1993, 50 years of planning and 20 years of environmental argument had taken place. The Chinese were conscious of the need to consider the environmental issues as a factor in attracting foreign investment for the world's biggest and most expensive dam. While the resettlement issues (1.2 M people were resettled) have dominated the current arguments, the other important issues are environment, economics and safety. Despite criticism from environmentalists, both at home and abroad, the Chinese went ahead with the project. With regard to resettlement, the Chinese appear to be much more considerate than some other countries in providing housing and agricultural land. Perhaps the main losses were suffered by cultural heritage sites and aquatic systems, rather than by the resettled population. (UK)

  3. International small dam safety assurance policy benchmarks to avoid dam failure flood disasters in developing countries

    Pisaniello, John D.; Dam, Tuyet Thi; Tingey-Holyoak, Joanne L.

    2015-12-01

    In developing countries small dam failure disasters are common yet research on their dam safety management is lacking. This paper reviews available small dam safety assurance policy benchmarks from international literature, synthesises them for applicability in developing countries, and provides example application through a case study of Vietnam. Generic models from 'minimum' to 'best' practice (Pisaniello, 1997) are synthesised with the World Bank's 'essential' and 'desirable' elements (Bradlow et al., 2002) leading to novel policy analysis and design criteria for developing countries. The case study involved 22 on-site dam surveys finding micro level physical and management inadequacies that indicates macro dam safety management policy performs far below the minimum benchmark in Vietnam. Moving assurance policy towards 'best practice' is necessary to improve the safety of Vietnam's considerable number of hazardous dams to acceptable community standards, but firstly achieving 'minimum practice' per the developed guidance is essential. The policy analysis/design process provides an exemplar for other developing countries to follow for avoiding dam failure flood disasters.

  4. Seismic response of concrete gravity dam reinforced with FRP sheets on dam surface

    Directory of Open Access Journals (Sweden)

    Hong ZHONG

    2013-10-01

    Full Text Available This paper aims at exploring the effects of anti-seismic reinforcement with the fiber-reinforced polymer (FRP material bonded to the dam surface in dam engineering. Time-history analysis was performed to simulate the seismic failure process of a gravity dam that was assumed to be reinforced at the locations of slope discontinuity at the downstream surface, part of the upstream face, and the dam heel. A damage model considering the influence of concrete heterogeneity was used to model the nonlinearity of concrete. A bond-slip model was applied to the interface between FRP and concrete, and the reinforcement mechanism was analyzed through the bond stress and the stress in FRP. The results of the crack pattern, displacement, and acceleration of the reinforced dam were compared with those of the original one. It is shown that FRP, as a reinforcement material, postpones the occurrence of cracks and slows the crack propagation, and that cracks emanating from the upstream surface and downstream surface are not connected, meaning that the reinforced dam can retain water-impounding function when subjected to the earthquake. Anti-seismic reinforcement with FRP is therefore beneficial to improving the seismic resistant capability of concrete dams.

  5. Analysis of deformations of large earth dams

    Science.gov (United States)

    Szostak-Chrzanowski, Anna; Massiéra, Michel; Chrzanowski, Adam

    2007-09-01

    Safety of earth dams depends on the proper design, construction, and monitoring of actual behaviour during the construction and during the operation of the structure. The most critical factor in the assessment of the safety threshold value of any structure is the acceleration of its deformation. Therefore, the designed accuracy of monitoring surveys must fulfill requirements of detecting accelerations at critical locations of the investigated object. As an example, time dependant behavior of a large embankment dam during filling up the reservoir has been analyzed and verified by comparing monitoring results with the deterministic (prediction) model of the deformation. The geotechnical and geodetic monitoring besides providing a warning system in case of an abnormal behaviour of the dam, may be used as a tool for a verification of design parameters where geotechnical parameters are of the highest importance. Modeling of deformation of earth dams is a complex process in which one should consider the nonlinear behaviour of the construction material, interaction between the structure and the underlying foundation strata, influence of water load on the structure and on the foundation bedrock, and the effects of water saturation. Due to the uncertainty of the model parameters, careful monitoring of the dam and its surroundings are required in order to verify and enhance the model. In addition, with properly designed monitoring surveys, one may also determine the actual deformation mechanism. The finite element method may be useful tool in the proper design of the monitoring scheme by providing information on the locations and magnitude of the expected maximum displacements and velocites of movements. The discussed problems are illustrated by three types of earth dams located in California, U.S.A. and in Quebec, Canada.

  6. Study on dynamic anti-sliding stability of a high gravity dam considering complex dam foundation

    Directory of Open Access Journals (Sweden)

    Deng-hong CHEN

    2011-06-01

    Full Text Available There existed some limitations when analyzing the anti-sliding seismic stability of dam-foundation system by traditional pseudo-static method and response spectrum method. The dynamic strength reduction method was used to study on the deep anti-sliding stability of a high gravity dam considering complex dam foundation under strong earthquake-induced ground action. The static analysis was firstly carried out by reducing the shear strength parameters of the dam foundation’s rock mass with equal proportion. Then, the time-history seismic analysis was carried out based on the static analysis. It was proposed as one of dynamic instability criterions that the peak values of the dynamic displacements and plastic strain energy change suddenly with increasing strength reduction coefficient. The elasto-plastic behavior of the dam foundation was idealized using Drucker–Prager yield criterion based on associated flow rule assumption. Through the static, dynamic strength reduction analysis and dynamic linear elastic analysis of the overflow dam monolith of a high gravity dam, the results’ reliability of elastic-plastic time history analysis was confirmed. The results also showed that the rock mass strength of the high gravity dam foundation has higher strength reserve coefficient. The instability criterions of dynamic strength reduction method proposed were feasible. Although the static anti-slide analysis methods and standards of gravity dam based on the numerical methods are being discussed at present, the dynamic calculation method and instability criterions proposed in this paper would provide some meaningful suggestions for the dynamic analysis of the similar projects.

    The digestive-enzyme secreting, gastric epithelial chief (zymogenic) cell is remarkable and underappreciated. Here, we discuss how all available evidence suggests that mature chief cells in the adult, mammalian stomach are postmitotic, slowly turning over cells that arise via a relatively long-lived progenitor, the mucous neck cell, The differentiation of chief cells from neck cells does not involve cell division, and the neck cell has its own distinct pattern of gene expression and putative physiological function. Thus, the ontogeny of the normal chief cell lineage exemplifies transdifferentiation. Furthermore, under pathophysiogical loss of acid-secreting parietal cell, the chief cell lineage can itself trasndifferentiate into a mucous cell metaplasia designated Spasmolytic Polypeptide Expressing Metaplasia (SPEM). Especially in the presence of inflammation, this metaplastic lineage can regain proliferative capacity and, in humans may also further differentiate into intestinal metaplasia. The results indicate that gastric fundic lineages display remarkable plasticity in both physiological ontogeny and pathophysiological pre-neoplastic metaplasia.

    2014-07-01

    Full Text Available Introduction: The role of the internal medicine chief resident includes various administrative, academic, social, and educational responsibilities, fulfillment of which prepares residents for further leadership tasks. However, the chief resident position has historically only been held by a few residents. As fourth-year chief residents are becoming less common, we considered a new model for rotating third-year residents as the chief resident. Methods: Online surveys were given to all 29 internal medicine residents in a single university-based program after implementation of a leadership curriculum and specific job description for the third-year chief resident. Chief residents evaluated themselves on various aspects of leadership. Participation was voluntary. Descriptive statistics were generated using SPSS version 21. Results: Thirteen junior (first- or second-year resident responses reported that the chief residents elicited input from others (mean rating 6.8, were committed to the team (6.8, resolved conflict (6.7, ensured efficiency, organization and productivity of the team (6.7, participated actively (7.0, and managed resources (6.6. Responses from senior residents averaged 1 point higher for each item; this pattern repeated itself in teaching evaluations. Chief resident self-evaluators were more comfortable running a morning report (8.4 than with being chief resident (5.8. Conclusion: The feasibility of preparing internal medicine residents for leadership roles through a rotating PGY-3 (postgraduate year chief residency curriculum was explored at a small internal medicine residency, and we suggest extending the study to include other programs.

    The Saddam dam is a very large dam in Iraq on the Tigris River, 80 kilometres upstream from the city of Mosul. It is a fill dam with a clayey silt core. The height of the dam is 120 meters and the capacity of the reservoir is 11 billions m3. But this dam has been built on foundations of gypsum that is a rock soluble in water. The impounding of the reservoir in 1986 has shown that, in spite of the grout curtain, substantial seepage has occurred (up to 1.4 m{sup 3}/s), as well as the dissolution of minerals from foundations (up to 80 tons per day). The substantial increase in permeability and seepage through the dam foundations results in a severe concern about the stability of the dam. The program of injection has been stopped in 1991, due to the circumstances. So there is a real risk that this dam would collapse through a quickly developing leak in the dike, resulting in the devastation of the rich agricultural valley of the Tigris River and in potential human losses at Mosul. A 10 to 20-meter high submersion wave would reach this town 3 to 4 hours after the collapse of the dam. An international action is urgently required to check the conditions of the dam and to propose remedial solutions, which may be a 120-meter deep concrete wall down to the calcareous floor existing below the soluble layers of the foundations.

    International Nuclear Information System (INIS)

    The successful Chief Executive Officer (CEO) will have recognized the benefits of, and have implemented, a total quality assurance program. The quality assurance program will be adequately defined in policies and procedures such that managers and supervisors of each organizational element understand their primary and supporting roles in carrying out an effective quality assurance program. The traditional practice of having all quality assurance activities reside in a quality assurance organization will have been cast aside. Instead, the quality assurance activities necessary to achieve and assure the quality of the desired end product will have been defined and assigned to responsible organization elements. The quality assurance organization's primary role will be to define the total quality assurance program, insure that the achieving and assuring functions are assigned in policies and procedures, conduct training necessary to have management and supervisors understand the total quality assurance program, measure the effectiveness of the program and feedback measurement data for improvements in the program. The successful CEO will have implemented a quality assurance program that provides for a graded approach for application of the program based upon the importance of the intended use of the product or service. The successful CEO will rely heavily on the scheduled progress reports and assessments to measure the pulse of his organization's successes and improvement needs. This paper will describe suggested approaches for the Quality Assurance Manager to implement a quality assurance program which results in his corporation's CEO being a supporter of and a driving force in the implementation of the quality assurance program

    2011-01-01

    The roles and responsibilities of nurses are expanding, as they become more involved in administration and leadership within their field. Nurses are taking on executive positions, which have become a crucial part of hospital organizations. With this expansion, an executive development program is necessary to provide nurses with the knowledge and competencies that these executive positions require. Their focus must evolve from singular bedside practice to the greater scope of health care administration. Leadership skills are extremely important, in addition to interpersonal, management, mentoring, and interprofessional skills. A number of nursing associations have worked to develop a set of curricula for nurse executive education, but a consistent and specific set of academic requirements has yet to be agreed upon. With the importance of the chief nursing officer's (CNO) role in the function of a hospital and the requirement of the knowledge of the changing health care system in the United States, it is essential that nurses are provided with proper education and training that will help them become successful nurse executives. Some suggestions include a dual MSN/MBA degree, a PhD in nursing, continuing education institutes, and mentoring programs. However, research must be done to clarify the best way to prepare CNOs for their roles. PMID:21900820

    Informatics competency adoption is a recognized issue across nursing roles in digital health practice settings. Further, it has been suggested that the health system's inability to reap the promised benefits of electronic health/patient records is, in part, a manifestation of inadequate development of informatics competency by chief nurse executives (CNEs) and other clinicians (Amendola 2008; Simpson 2013). This paper will focus on CNE informatics competency and nursing knowledge development as it pertains to the Big Data revolution. With the paper's aim of showing how CNEs armed with informatics competency can harness the full potential of Big Data offering new opportunities for nursing knowledge development in their clinical transformation roles as eHealth project sponsors. It is proposed that informatics-savvy CNEs are the new transformational leaders of the digital age who will have the advantage to successfully advocate for nurses in leading 21st-century health systems. Also, transformational CNEs armed with informatics competency will position nurses and the nursing profession to achieve its future vision, where nurses are perceived by patients and professionals alike as knowledge workers, providing the leadership essential for safe, quality care and demonstrating nursing's unique contributions to fiscal health through clinically relevant, evidence-based practices (McBride 2005b).

    Fu-gang Xu

    2013-01-01

    Full Text Available Dam breaks of landslide dams are always accompanied by large numbers of casualties, a large loss of property, and negative influences on the downstream ecology and environment. This study uses the Jiadanwan landslide dam, created by the Wenchuan earthquake, as a case study example. Several laboratory experiments are carried out to analyse the dam-break mechanism of the landslide dam. The different factors that impact the dam-break process include upstream flow, the boulder effect, dam size, and channel discharge. The development of the discharge channel and the failure of the landslide dam are monitored by digital video and still cameras. Experimental results show that the upstream inflow and the dam size are the main factors that impact the dam-break process. An excavated discharge channel, especially a trapezoidal discharge channel, has a positive effect on reducing peak flow. The depth of the discharge channel also has a significant impact on the dam-break process. The experimental results are significant for landslide dam management and flood disaster prevention and mitigation.

  13. River restoration by dam removal: Enhancing connectivity at watershed scales

    2016-05-01

    Full Text Available Abstract The prolonged history of industrialization, flood control, and hydropower production has led to the construction of 80,000 dams across the U.S. generating significant hydrologic, ecological, and social adjustments. With the increased ecological attention on re-establishing riverine connectivity, dam removal is becoming an important part of large-scale river restoration nationally, especially in New England, due to its early European settlement and history of waterpower-based industry. To capture the broader dimensions of dam removal, we constructed a GIS database of all inventoried dams in New England irrespective of size and reservoir volume to document the magnitude of fragmentation. We compared the characteristics of these existing dams to the attributes of all removed dams over the last ∼25 years. Our results reveal that the National Inventory of Dams significantly underestimates the actual number of dams (4,000 compared to >14,000. To combat the effects of these ecological barriers, dam removal in New England has been robust with 127 dams having been removed between ca. 1990–2013. These removed dams range in size, with the largest number (30% ranging between 2–4 m high, but 22% of the removed dams were between 4–6 m. They are not isolated to small drainage basins: most drained watersheds between 100–1,000 km2. Regionally, dam removal has re-connected ∼3% (3,770 river km of the regional river network although primarily through a few select dams where abundant barrier-free river lengths occur, suggesting that a more strategic removal approach has the opportunity to enhance the magnitude and rate of river re-connection. Given the regional-scale restoration of forest cover and water quality over the past century, dam removal offers a significant opportunity to capitalize on these efforts, providing watershed scale restoration and enhancing watershed resilience in the face of significant regional and global anthropogenic

    1999-07-01

    Topics concerning the problems associated with older and aging dams are considered including: what can be done to extent the lifetime of an old dam, the decision to decommission a dam based on a value judgment that the risk of maintaining the dam is too great for society's acceptance, the possibility of change in the level of risk tolerance with time in a technological environment, traditional surveillance methods used by dam owners in the Y2K situation, and the unreality of dam immortality. Trends and means for preserving older dams for their owner's purposes are outlined, as well as their lifetime compared to that of the downstream systems they serve. Despite the fact that we live in a throwaway society, dam owners cannot just leave their dam asset when they are through with using it. Someone has to maintain the dam, or ensure that it is safely decommissioned when the owner is finished with it. On a worldwide scale the available pool of experienced dam engineers is shrinking. This problem needs to be addressed by a shift towards operating and dam safety management skills based on a firm awareness of dam design principles. A shift in society's expectations has occurred such that dam designers and owners must now recognize the impact a dam can have both on its natural and social environments. Because of the increasing emphasis on paying attention to the impacts of people's activities on the planet, engineers more than anyone else must have a significant influence in that direction. 9 refs.

    This paper discussed a risk reduction study conducted for 10 large tailings dams located at a central tailings facility in Ontario. Located near large industrial and urban developments, the tailings dams were built using an upstream method of construction that did not involve beach compaction or the provision of under-drainage. The study provided a historical background for the dam and presented results from investigations and instrumentation data. The methods used to develop the dam configurations were discussed, and remedial measures and risk assessment measures used on the dams were reviewed. The aim of the study was to address key sources of risk, which include the presence of high pore pressures and hydraulic gradients; the potential for liquefaction; slope instability; and the potential for overtopping. A borehole investigation was conducted and piezocone probes were used to obtain continuous data and determine soil and groundwater conditions. The study identified that the lower portion of the dam slopes were of concern. Erosion gullies could lead to larger scale failures, and elevated pore pressures could lead to the risk of seepage breakouts. It was concluded that remedial measures are now being conducted to ensure slope stability. 6 refs., 1 tab., 6 figs.

  5. RNA interference mitigates motor and neuropathological deficits in a cerebellar mouse model of Machado-Joseph disease.

    Directory of Open Access Journals (Sweden)

    Clévio Nóbrega

    Full Text Available Machado-Joseph disease or Spinocerebellar ataxia type 3 is a progressive fatal neurodegenerative disorder caused by the polyglutamine-expanded protein ataxin-3. Recent studies demonstrate that RNA interference is a promising approach for the treatment of Machado-Joseph disease. However, whether gene silencing at an early time-point is able to prevent the appearance of motor behavior deficits typical of the disease when initiated before onset of the disease had not been explored. Here, using a lentiviral-mediated allele-specific silencing of mutant ataxin-3 in an early pre-symptomatic cerebellar mouse model of Machado-Joseph disease we show that this strategy hampers the development of the motor and neuropathological phenotypic characteristics of the disease. At the histological level, the RNA-specific silencing of mutant ataxin-3 decreased formation of mutant ataxin-3 aggregates, preserved Purkinje cell morphology and expression of neuronal markers while reducing cell death. Importantly, gene silencing prevented the development of impairments in balance, motor coordination, gait and hyperactivity observed in control mice. These data support the therapeutic potential of RNA interference for Machado-Joseph disease and constitute a proof of principle of the beneficial effects of early allele-specific silencing for therapy of this disease.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed hydrologic and hydraulic analyses to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4.25 square kilometers.The hydrologic assessment was designed to determine the outflow hydrographs and peak discharges for Lago El Guineo and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation event, (2) a 24-hour probable maximum precipitation event, and (3) a 24-hour, 100-year recurrence rainfall event. The hydraulic study simulated a dam failure of Lago El Guineo Dam using flood hydrographs generated from the hydrologic study.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed hydrologic and hydraulic analyses to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4.25 square kilometers.The hydrologic assessment was designed to determine the outflow hydrographs and peak discharges for Lago El Guineo and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation event, (2) a 24-hour probable maximum precipitation event, and (3) a 24-hour, 100-year recurrence rainfall event. The hydraulic study simulated a dam failure of Lago El Guineo Dam using flood hydrographs generated from the hydrologic study. The simulated dam failure generated a hydrograph that was routed downstream from Lago El Guineo Dam through the lower reaches of the Río Toro Negro and the Río Grande de Manatí to determine water-surface profiles developed from the event-based hydrologic scenarios and “sunny day” conditions.

  8. Rehabilitation of an 80 year old Ambursen dam

    International Nuclear Information System (INIS)

    The Abitibi-Price Inc. hydroelectric facility at Bishop's Falls, NF, as built comprised an earth dam, a hollow concrete Ambursen type dam, and intake works at the powerhouse, as the main retaining structures. On January 13, 1983, an unprecedented flood occurred in the region which completely destroyed the earth dam connecting the powerhouse building to the riverbank of the town of Bishop's Falls. Major items of remedial work included a new earth dam and a new gated spillway. The flood did not result in any serious damage to the Ambursen dam, but exposure of the dam to the elements did result in stress which required rehabilitation. The favourable performance of the dam through a long service life in a northern Canadian climatic setting was a significant factor in the decision that the structure could be used without serious modification for at least 50 years. The evaluation of the dam, together with the distress experienced as a result of the flood and the remedial action applied are described as a case history. On the basis of condition and stability analysis, it was considered that repairs consisting of a new lining on the upstream side, grouting of deformation related cracking in the interior of the dam, and shotcrete treatment to the exterior of the downstream side, would give the dam a long service life. These remedial actions were applied, and the performance of the dam to date has met design expectations. 26 refs., 10 figs

    While many jurisdictions in Canada use the Canadian Dam Association (CDA) dam safety guidelines, their applicability to the safety of mining dams is limited. Mining dams are some of the largest containment structures in the world, and impound millions of cubic meters of mine process residues in both solid and liquid form. This study presented a review of dam safety regulatory frameworks for mining dams located in various countries. The aim of the study was to compare the Canadian framework with various dam safety legislations in order to evaluate Canada's current status and recommend best practices in dam safety regulations. The study reviewed incremental consequence classifications; best practices in operation, surveillance and maintenance manuals and procedures; emergency preparedness plans; and dam safety inspections. The study showed that Canada has limited documentation regulating the safe management of tailings facilities, and does not have an all-encompassing national guideline for mining dams. It was concluded that an incremental consequence classification (ICC) system should be developed specifically for mining dams. 12 refs.

  10. Seismic failure modes and seismic safety of Hardfill dam

    2013-04-01

    Full Text Available Based on microscopic damage theory and the finite element method, and using the Weibull distribution to characterize the random distribution of the mechanical properties of materials, the seismic response of a typical Hardfill dam was analyzed through numerical simulation during the earthquakes with intensities of 8 degrees and even greater. The seismic failure modes and failure mechanism of the dam were explored as well. Numerical results show that the Hardfill dam remains at a low stress level and undamaged or slightly damaged during an earthquake with an intensity of 8 degrees. During overload earthquakes, tensile cracks occur at the dam surfaces and extend to inside the dam body, and the upstream dam body experiences more serious damage than the downstream dam body. Therefore, under the seismic conditions, the failure pattern of the Hardfill dam is the tensile fracture of the upstream regions and the dam toe. Compared with traditional gravity dams, Hardfill dams have better seismic performance and greater seismic safety.

    2012-04-01

    Introduction: Water level in the observation wells is measured regularly and one of the reasons is evaluation of the safety of the water constructions. In this paper we are exploring the reliability of the measuring devices that are responsible for evaluation of the safety of the two largest and the most important dams in Slovakia. We test ability of selected statistical methods to detect early inaccuracies of measuring devices and thus improve the evaluation of the safety of the water constructions. As a follow-up study, we used the time series model (Neural network) to predict water levels in the observation wells that were considered to be without defects. Neural Network is also able to show dynamics of the filtration stability of the observational well. Methods: On the Liptovska Mara dam weekly data was used as a monitoring tool. On the Gabcikovo dam five minute time series of the measurements of the water level in observation wells around the right lock chamber were used. Data from the measuring devices of the dams were explored with boxplots, correlations, neural network, etc. The mentioned statistical tools analyze time series and detect the errors that measuring devices make when generating data and can be used to predict errors even in real time. In the second step, agreement between predicted data from neural network and measured data in the real time was evaluated. We used grid search for finding the optimal number of neurons and then predicted errors by using this model. The ability of the neural network in evaluation of the sealing of the dilatation joints on the filtration stability in the years 2009 - 2011 is presented. Results: From the 18 selected measuring devices on the Liptovska Mara dam there are only 3 devices which can be considered as reliable. On the Gabcikovo dam, 8 of 9 measuring devices (observation wells around right lock chamber) were considered as a reliable. There was very good agreement between the predicted and measured data at the

    2004-04-01

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

The survey consisted of questions defining demographics, duties of the typical CR, and opinions regarding the level of support and training received. Multiple choice, Likert scale (1 strong agreement, 5 strong disagreement and short-answer responses were used. We analyzed associations between CR and PD responses using Chi-square, Student’s T and Mann-Whitney U tests.Results: Seventy-six percent of CRs and 65% of PDs responded and were similar except for age (31 vs. 42 years; p<0.001. CR respondents were most often male, in year 3 of training and held the position for 12 months. CRs and PDs agreed that the assigned level of responsibility is appropriate (2.63 vs. 2.73, p=0.15; but CRs underestimate their influence in the residency program (1.94 vs. 2.34, p=0.002 and the emergency department (2.61 vs. 3.03, p=0.002. The majority of CRs (70% and PDs (77% report participating in an extramural training program, and those CRs who participated in training felt more prepared for their job duties (2.26 vs. 2.73; p=0.03.Conclusion: EM CRs feel they have appropriate job responsibility but believe they are less influential in program and department administration than PD respondents. Extramural training programs for incoming CRs are widely used and felt to be helpful. [West J Emerg Med. 2010; 11(2:120-125.

    On 1 January 2005 I become Editor-in-Chief of Plasma Physics and Controlled Fusion. I look forward to assisting contributors, referees and the Board in maintaining the high standards of this international journal, whose bibliometric impact factor has consistently matched or exceeded that of other journals in the field. The robust, good health of Plasma Physics and Controlled Fusion reflects that of its user communities. With a decision to proceed to the construction of ITER apparently imminent, magnetic confinement fusion research is preparing to take a major step forwards. A new generation of laser-plasma interaction facilities for inertial fusion research is also rising at key sites around the world. Technical progress in our field is underpinned by scientific excellence, and the publication of results in Plasma Physics and Controlled Fusion will, I hope, continue to play its part. The journal will continue to offer the benefits of refereeing by two experts, combined with the rapid turnaround achieved by the highly efficient editorial office at the Institute of Physics Publishing in Bristol. Looking elsewhere, there may be opportunities for gentle incremental broadening of the scientific scope of the journal, in the medium term. One looks in particular to those branches of plasma physics that, in recent years, have become more strongly represented in the series of conferences organized by the Plasma Physics Division of the European Physical Society. The recent special issue of Plasma Physics and Controlled Fusion (Plasma Phys. Control. Fusion 46 (2004) B1--592) provides an indication. Finally, it is a pleasure to thank my predecessor, Professor Ian Hutchinson of the Massachusetts Institute of Technology, for handing on his role with the journal in such promising condition.

  15. A Science Superior to Music: Joseph Sauveur and the Estrangement between Music and Acoustics

    Science.gov (United States)

    Fix, Adam

    2015-09-01

    The scientific revolution saw a shift from the natural philosophy of music to the science of acoustics. Joseph Sauveur (1653-1716), an early pioneer in acoustics, determined that science as understood in the eighteenth century could not address the fundamental problems of music, particularly the problem of consonance. Building on Descartes, Mersenne, and Huygens especially, Sauveur drew a sharp divide between sound and music, recognizing the former as a physical phenomenon obeying mechanical and mathematical principles and the latter as an inescapably subjective and unquantifiable perception. While acoustics grew prominent in the Académie des sciences, music largely fell out of the scientific discourse, becoming primarily practiced art rather than natural philosophy. This study illuminates what was considered proper science at the dawn of the Enlightenment and why one particular branch of natural philosophy—music—did not make the cut.

    Lützen, Jesper

    As many of his contemporaries did, Joseph Liouville often emphasized the importance of physics for mathematical research. His own works provide a host of examples of interactions between mathematics and physics. This paper analyses some of them. It is shown how Laplacian physics gave rise to Liouville's theory of differentiation of arbitrary order, how Kelvin's research on electrostatics gave rise to Liouville's theorem about conformal mappings and how the theory of heat conduction gave rise to Sturm-Liouville theory. It will be shown how the problem of the shape of the planets was an important inspiration for Liouville's far reaching studies of Lamé functions and spectral theory of a particular type of integral operators. Finally the interactions between Liouville's work on mechanics and differential geometry will be discussed.

    Machado-Joseph disease (MJD) and Holguin ataxia (SCA2) are autosomal dominant multisystem degenerations with spinocerebellar involvement that are predominant among people of Portuguese-Azorean and of Cuban descent, respectively. Their clinical distinction may at times be difficult to make in individual patients, due to significant phenotypic overlapping (similar overall age-of-onset and duration of cerebellar ataxia, eye movement, and, often, other common problems). The recent mapping of SCA2 to chromosome 12q provided another candidate region for linkage studies of MJD. Original data on 10 families with Holguin ataxia show that the locus of phenylalanine hydroxylase (PAH) on chromosome 12q is linked to SCA2 at 4 cM and is thus far its closest marker. The exclusion of linkage 15 cM on each side of PAH in 16 families with MJD shows that these two forms of dominant ataxia are genetically distinct and at different chromosomal locations (nonallelic). 20 refs., 2 tabs.

    Joseph Lovell, trained in medicine at Harvard and in military medicine/surgery by the War of 1812, became the first Surgeon General to sit on the reorganised army staff at the tender age of 29 in 1818. With a keen intellect, medical acumen, and wartime experiences for his tools and a close supporting relationship with Commanding General Jacob Jennings Brown and Secretary of War John C Calhoun (1728-1850), Lovell constructed an efficient and effective organisational and administrative framework for the new Medical Department of the US Army. Moreover, he not only redefined the role of the American military physician but also established the professional dignity, respectability and value of the medical officer among line officers and staff. Lovell's 18-year tenure came to an abrupt end, but the operational framework he created became both foundation and legacy for his successors.

  3. A life more ordinary: the dull life but interesting times of joseph dalton hooker.

    Endersby, Jim

    2011-01-01

    The life of Joseph Dalton Hooker (1817-1911) provides an invaluable lens through which to view mid-Victorian science. A biographical approach makes it clear that some well-established narratives about this period need revising. For example, Hooker's career cannot be considered an example of the professionalisation of the sciences, given the doubtful respectability of being paid to do science and his reliance on unpaid collectors with pretensions to equal scientific and/or social status. Nor was Hooker's response to Darwin's theories either straightforward or contradictory; it only makes sense as carefully crafted equivocation when seen in the context of his life and career. However, the importance of Hooker's life is ultimately its typicality; what was true of Hooker was true of many other Victorian men of science.

  4. Laparoscopic Scar: a mimicker of Sister Mary Joseph's nodule on positron emission tomography/CT

    International Nuclear Information System (INIS)

    Positron emission tomography/CT is an established imaging method in the diagnosis and staging of cancers. 18F-fluoro-2-deoxy-D-glucose (FDG) is the most commonly used radiotracer in positron emission tomography/CT. It is a tumour viability agent and usually its uptake within a lesion reflects the presence of a viable tumour tissue. However, false-positive FDG uptake is known to occur in benign processes of either inflammatory or infectious aetiology. We describe FDG uptake at the site of laparoscopic scar that mimicked Sister Mary Joseph's nodule in a patient with gastric adenocarcinoma. Here, the knowledge of the patient's history and subtle imaging findings helped in accurate staging of the patient. In this case report, we emphasize the value of the knowledge of the patient history and awareness of different pitfalls of FDG to achieve a correct diagnosis on positron emission tomography/CT

    Full Text Available Charles-Joseph de Ligne (1735-1814, a Wallon and European Prince, subject of the Austro-Hungary Empire, a heartbreaker of the French Europe, is considered the most famous representative of literary cosmopolitanism. War, love and writing were inseparable in his life. He took part in numerous military campaigns, serving both Austria and Russia, as a Russian colonel, a commander of the order of Maria Theresa, and an Austrian fi eld marshal. He authored various texts related to war; he admired heroism of Charles II, Conde, the tactics of Frederick II, the strategies of Napoleon, Catherine II. The latter was immportalized in de Ligne’s various texts representing different literary genres. The Prince was clearly fascinated by the Empress, and he depicted her in a positive light as an educated person, both agreable and determined. Can we, however, talk about the documentary character of his work ? Instead, the Prince seems to be a documentalist-interpreter.

    Earthquake activity and seismic hazard analysis are important components of the seismic aspects for very essential structures such as major dams. The Aswan High Dam (AHD) created the second man-made reservoir in the world (Lake Nasser) and is constructed near urban areas pose a high-risk potential for downstream life and property. The Dam area is one of the seismically active regions in Egypt and is occupied with several cross faults, which are dominant in the east-west and north-south. Epicenters were found to cluster around active faults in the northern part of Lake and AHD location. The space-time distribution and the relation of the seismicity with the lake water level fluctuations were studied. The Aswan seismicity separates into shallow and deep seismic zones, between 0 and 14 and 14 and 30 km, respectively. These two seismic zones behave differently over time, as indicated by the seismicity rate, lateral extent, b-value, and spatial clustering. It is characterized by earthquake swarm sequences showing activation of the clustering-events over time and space. The effect of the North African drought (1982 to present) is clearly seen in the reservoir water level. As it decreased and left the most active fault segments uncovered, the shallow activity was found to be more sensitive to rapid discharging than to the filling. This study indicates that geology, topography, lineations in seismicity, offsets in the faults, changes in fault trends and focal mechanisms are closely related. No relation was found between earthquake activity and both-ground water table fluctuations and water temperatures measured in wells located around the Kalabsha area. The peak ground acceleration is estimated in the dam site based on strong ground motion simulation. This seismic hazard analyses have indicated that AHD is stable with the present seismicity. The earthquake epicenters have recently took place approximately 5 km west of the AHD structure. This suggests that AHD dam must be

    The profound study of nature is the most fertile source of mathematical discoveries. Not only does this study, by offering a definite goal to research, have the advantage of excluding vague questions and futile calculations, but it is also a sure means of moulding analysis itself, and discerning those elements in it which it is still essential to know and which science ought to conserve. These fundamental elements are those which recur in all natural phenomena. Joseph Fourier pure mathematics enables us to discover the concepts and laws connecting them, which gives us the key to the understanding of the phenomena of nature. Albert Einstein This article deals with a brief biographical sketch of Joseph Fourier, his first celebrated work on analytical theory of heat, his first great discovery of Fourier series and Fourier transforms. Included is a historical development of Fourier series and Fourier transforms with their properties, importance and applications. Special emphasis is made to his splendid research contributions to mathematical physics, pure and applied mathematics and his unprecedented public service accomplishments in the history of France. This is followed by historical comments about the significant and major impact of Fourier analysis on mathematical physics, probability and mathematical statistics, mathematical economics and many areas of pure and applied mathematics including geometry, harmonic analysis, signal analysis, wave propagation and wavelet analysis. Special attention is also given to the Fourier integral formula, Brownian motion and stochastic processes and many examples of applications including isoparametric inequality, everywhere continuous but nowhere differentiable functions, Heisenberg uncertainty principle, Dirichlets' theorem on primes in arithmetic progression, the Poisson summation formula and solutions of wave and diffusion equations. It is also shown that Fourier coefficients c n (t) in the Fourier expansion of a scalar field

    Dams provide beneficial functions such as flood control, recreation, and storage of water supplies, but they also entail risk; dam breaches and resultant floods can cause substantial property damage and loss of life. The State of Oklahoma requires each owner of a high-hazard dam, which the Federal Emergency Management Agency defines as dams for which failure or improper operation probably will cause loss of human life, to develop an emergency action plan specific to that dam. Components of an emergency action plan are to simulate a flood resulting from a possible dam breach and map the resulting downstream flood-inundation areas. The resulting flood-inundation maps can provide valuable information to city officials, emergency managers, and local residents for planning an emergency response if a dam breach occurs.

    Full Text Available Landfill liners from dam reservoir sediments. Every municipal solid waste landfill has to be properly secured to protect the natural environment from possible leachate. Most often an artificial sealing is used, which is based on a soil liner from cohesive soils (clays, silts. Usability evaluation of bottom sediments from Rzeszowski Reservoir for building these liners was presented in the paper. Sediments from dam reservoirs, gathered as a result of the siltation process, can be a valuable material for earthworks purposes. Determination of their possible ways of usage is important, especially before the planned dredging, because thanks to that this material will not be put on a heap. Based on the analysis of the geotechnical parameters of these sediments it was stated that this material can be preliminary allowed for using in liners.

    Full Text Available The channel erosion downstream spillway dams in non-cohesive materials has been analyzed from the viewpoint of methods of similarity and dimension theory. The obtained criterion equation connects the maximum depth of the local erosion with its determining parameters: length of concrete lining of bed in the down water of the spillway dam; Froude number at the contracted cross section; Archimedes and Reynolds criterions; submergence factor of hydraulic jump. The problem may be formulated as follows: the geometric size of the structure, kinematics and dynamics of the flows in the model are similar to that in the prototype. Conditions under which the characteristic depth of the local erosion in the model would be recomputed into the prototype, like any geometric size, are being discussed.

    The integrity and safety of concrete dams are seriously affected by the existing cracks in dam bodies,and some serious cracks may cause dam failure or disaster.The propagation of cracks in concrete dams is accompanied by changes in energy distribution,which can be represented by changes in the structure's system entropy.Therefore,the entropy theory can be used in analyzing the behavior of dam cracks.Due to the randomness and locality of crack propagation,it is difficult to predict the location of cracks by traditional monitoring methods.To solve this problem,the influence of spatial positions of monitoring points on inspection zones is represented by a weight index,and the weight index is determined by the distance measure method proposed in this paper.Through the weighted linear fusion method,the entropy of multiple monitoring points is obtained for analyzing the behavior of dam cracks in the selected zones.Meanwhile,the catastrophe theory is used as the variation criterion of an entropy sequence in order to predict the instability time of dam cracks.Case studies are put forward on a high arch dam,and the fusion entropy is calculated according to the monitoring data from strain gauges.Results show that the proposed method can effectively predict the occurrence time and location of dam cracks regardless of the layout of monitoring instruments,and it is a new way to analyze the occurrence and propagation of dam cracks.

    Reservoirs play a vital role in economic development and flood control.Nevertheless,both human and natural factors may lead to dam failures with catastrophic consequences.Analyzing the data of dam failure events from 1954 to 2003 and using the method of energy spectrum analysis,this paper studies the periodicity of dam failures.The rate of failure of different dam ages is analyzed.The climate is the main factor affecting the rate of dam failure.Climate diagrams are used to analyze the spatial distribution of dam failure events in China.High rate of dam failure occurs with 25-year and 12.5-year periods.The distribution of the percentage of dam failure shows an L-shape as a function of service age.The first 5 years of operation is known as the "infant period",during which,the probability of dam failure is much higher than during any other periods.The failure rate in areas near or north to the 400 mm annual isopluvial line is notably higher than other areas.In areas with high temperature difference among seasons have a high annual average dam failure rate.

    This paper addresses technical issues related to seismic design practices and current evaluation methods in Japan and the United States. Nonlinear analysis procedures can identify the ultimate capacity of existing concrete dams, taking into account the most critical nonlinear phenomena controlling the response. A numerical model of a non-overflow monolith of Koyna Dam, subject to earthquake motion, is used as a case study to compare the different approaches for seismic evaluation of concrete gravity dams currently employed in the two countries. The complexity of nonlinear analysis procedures and the scarcity of appropriate calibration strategies force analysts to frequently interpret results using their own judgment. It was concluded that the influence of the input parameters and ground excitation on the nonlinear dynamic response should be investigated in order to identify the most critical conditions. It was also suggested that methodologies for qualitative damage estimation based on results from linear analyses could be used to develop a systematic assessment tool and reference framework for the adequate interpretation of results. 14 refs., 2 tabs., 13 figs.

    Although Sabo dams are an efficient method for river and basin management,traditional Sabo dams have a great impact on ecology and landscape.Moreover,such dams are hit and often damaged by great impulsive force when they block the debris flow.Therefore,alternative shapes for Sabo dam deserve thorough investigation.In this investigation,a curved dam was designed by changing the upstream-dam-surface geometric shape to reduce the impulsive force of the debris flow,with enhanced stability and reduced concrete mass being the anticipated outcomes.In this study,the flume and laboratory facilities simulated the impulsive force of the debris flow to the Sabo dams.Three geometric forms,including vertical,slanted and curved Sabo dams,were used to determine the impulsive force.Impulsive force theories of the debris flow were derived from the momentum equation and the Bernoulli equation.In these,the impulsive force was balanced by the friction force of the Sabo dam and the opposite force of the load cell behind the dam as it was hit by the debris flow.Positive correlations were found when comparing the experimental data with the theoretical results.These findings suggest that our impulsive force theory has predictive validity with regard to the experimental data.The results from both theory and experimental data clearly show that curved dams were sustained less force than the other dams under the same debris flow.This comparison demonstrates the importance of curved geometry for a well-designed Sabo dam.

The system includes the following features: mixing amount by mixing ratio and mixing intervals can be instructed from a concrete placing site by using a wireless handy terminal; concrete is mixed automatically in a batcher plant; a transfer car is started, and concrete is charged into a bucket automatically; the mixed concrete is determined of its properties automatically; labor cost can be reduced, the work efficiency improved, and the safety enhanced; and the system introduction has resulted in unattended operation from the aggregate draw-out to a bunker line, manpower saving of five persons, and reduction in cycle time by 10%. 11 figs., 2 tabs.

  5. Simulating dam-breach flood scenarios of the Tangjiashan landslide dam induced by the Wenchuan Earthquake

    Full Text Available Floods from failures of landslide dams can pose a hazard to people and property downstream, which have to be rapidly assessed and mitigated in order to reduce the potential risk. The Tangjiashan landslide dam induced by the Mw = 7.9 2008 Wenchuan earthquake had impounded the largest lake in the earthquake affected area with an estimated volume of 3 × 108 m3, and the potential catastrophic dam breach posed a serious threat to more than 2.5 million people in downstream towns and Mianyang city, located 85 km downstream. Chinese authorities had to evacuate parts of the city until the Tangjiashan landslide dam was artificially breached by a spillway, and the lake was drained. We propose an integrated approach to simulate the dam-breach floods for a number of possible scenarios, to evaluate the severity of the threat to Mianyang city. Firstly, the physically-based BREACH model was applied to predict the flood hydrographs at the dam location, which were calibrated with observational data of the flood resulting from the artificial breaching. The output hydrographs from this model were inputted into the 1-D–2-D SOBEK hydrodynamic model to simulate the spatial variations in flood parameters. The simulated flood hydrograph, peak discharge and peak arrival time at the downstream towns fit the observations. Thus this approach is capable of providing reliable predictions for the decision makers to determine the mitigation plans. The sensitivity analysis of the BREACH model input parameters reveals that the average grain size, the unit weight and porosity of the dam materials are the most sensitive parameters. The variability of the dam material properties causes a large uncertainty in the estimation of the peak flood discharge and peak arrival time, but has little influence on the flood inundation area and flood depth downstream. The effect of cascading breaches of smaller dams downstream of the Tangjiashan dam was

  6. Stability of the dam at the Sillamaee tailings pond

    International Nuclear Information System (INIS)

    The tailings pond at Sillamaee is contained by a dam located 30 to 50 meters from the waters of the Baltic Sea. The tailings pond was begun in the 1950s, at which time the height of the dam was 12 m. It has been increased since then to 25 m. The apparently realtively unplanned buildup of the dam and lack of maintenance have led to a decrease in the stability of the dam. In its present conditions, the dam of the tailings pond is less stable than is recommended by international practice. Estonian, Norwegian, Swedish, and Finnish specialists have investigated various aspects of the dam's stability. This paper summarizes their findings and makes recommendations for further work

    Fourteen dams over 30 years old are operating in Iran. These dams have important roles in flood control, hydroelectric power generation and water supply. Due to several factors, such as the lack of maintenance, repairs and qualified personnel , these dams represent a risk to public safety and are not able to operate. This paper provided a review of the status of old dams, operating for more than 50 years, in Iran. The history of each dam was investigated. The study identified key issues such as: operation, maintenance and repair, regular and accurate inspections and rehabilitation. It was also recommended that guidelines be developed to give a better understanding of these old dams. It was also proposed that a rehabilitation and reconstruction fund be created. Finally, training of new expert personnel through training courses and education programs was proposed.

    Dams that comprise broadly and widely graded glacial materials, such as moraines, have been found to be susceptible to internal erosion, perhaps more than dams of other soil types. Internal erosion washes out fine-grained particles from the filling material; the erosion occurs within the material itself or at an interface to another dam zone, depending on the mode of initiation. Whether or not internal erosion proceeds depend on the adequacy of the filter material. If internal erosion is allo...

    As I begin my tenure as Editor-in-Chief of Journal of Physics: Condensed Matter (JPCM), I look upon this opportunity as both an honour and a real challenge. The journal is in great shape thanks to the work of my predecessors, Marshall Stoneham and David Ferry. The journal's solid reputation is based largely on the work these gentlemen have done over the past decade. The other main reason for the success of JPCM is the amazing staff in Bristol; keep up the good work, please. When discussing the journal with scientists from all corners of the globe, one thing is always mentioned—JPCM is a very reliable journal with well-written, high-quality papers, and a fast but rigorous peer-review process that provides fair, detailed and constructive referee reports for the benefit of authors. This is due almost entirely to our great authors and referees; we rely on them every day—thank you. As the new Editor-in-Chief I hope to continue to improve still further the journal's status in condensed matter science. As mentioned above, our reputation is excellent, but the reality is that we live in a world of bibliometrics and rankings. Over the past few years JPCM has been repositioned as a journal at the forefront of condensed matter physics, and the impact of the journal should increase further as a result of continued emphasis on commissioning in cutting-edge areas identified by the Editorial Board and the journal team. In addition to regular papers, JPCM has a number of other content streams that authors and readers can benefit from. Fast track communications (FTCs) offer exceptionally fast publication for work of the highest impact and urgency. By their select nature, FTCs benefit from personal treatment by the Editorial Board and the average receipt-to-first-decision time is just 11 days (the average receipt-to-publication time is just 45 days). Topical reviews in JPCM make the journal one of the most authoritative sources of review content for condensed matter physics

    The main objective of this work was to detect water leakage origin combining conventional, tracing and isotope techniques. The investigation was performed by a research team from the 'Algiers Nuclear Research Centre' in collaboration with engineers from the 'National Agency for Dams'. The chemical and isotopic results have shown no influence of dam water on the water sampled at the piezometers and drains that are present in the close neighbourhood of the dam. However, the water flowing at drain D15 has exhibited the nearest quality to that dam. Dye tracing has shown a water circulation through complex pathways for the left bank. (author)

    Stochastic boundary integral equations for analyzing large structures are obtained from the partial derivatives of basic random variables. A stochastic boundary element method based on the equations is developed to solve engineering problems of gravity dams using random factors including material parameters of the dam body and the foundation, the water level in the upper reaches, the anti-slide friction coefficient of the dam base, etc. A numerical example shows that the stochastic boundary element method presented in this paper to calculate the reliability index of large construction projects such as a large concrete gravity dam has the advantages of less input data and more precise computational results.

  2. Environmental impacts of small dams on agriculture and ground water development: a case study of Khan pur Dam, Pakistan

    International Nuclear Information System (INIS)

    The water scarcity issues are increasing through out the world. Pakistan is also facing water crises and its water demands are increasing every day. During this research it is investigated that small dams are playing an important role for the sustainability of groundwater and agriculture. The main objective of this study was to assess the environmental impacts of small dam on agricultural and ground water. Proper planning and management of small dams may improve the sustainable agriculture in Pakistan. It is also concluded that small dams are significantly contributing towards economy, environment, local climate, recreational activities and crop production. Small dams can also be utilized for the production of electricity at local level. On the other hand, water management issues can be resolved by the involvement of local farmer's associations. Water losses through seepage, unlined channels and old irrigation methods are most critical in developing world. Considering the overall positive environmental impacts, construction of small dams must be promoted. (author)

    Diversion dams can negatively affect emigrating juvenile salmon populations because fish must pass through the impounded river created by the dam, negotiate a passage route at the dam and then emigrate through a riverine reach that has been affected by reduced river discharge. To quantify the effects of a main-stem diversion dam on juvenile Chinook salmon in the Yakima River, Washington, USA, we used radio telemetry to understand how dam operations and river discharge in the 18-km reach downstream of the dam affected route-specific passage and survival. We found evidence of direct mortality associated with dam passage and indirect mortality associated with migration through the reach below the dam. Survival of fish passing over a surface spill gate (the west gate) was positively related to river discharge, and survival was similar for fish released below the dam, suggesting that passage via this route caused little additional mortality. However, survival of fish that passed under a sub-surface spill gate (the east gate) was considerably lower than survival of fish released downstream of the dam, with the difference in survival decreasing as river discharge increased. The probability of fish passing the dam via three available routes was strongly influenced by dam operations, with passage through the juvenile fish bypass and the east gate increasing with discharge through those routes. By simulating daily passage and route-specific survival, we show that variation in total survival is driven by river discharge and moderated by the proportion of fish passing through low-survival or high-survival passage routes.

    This paper discussed a systematic methodology for the hydromechanical coupled numerical analysis of earth dams constructed with unsaturated collapsible soil. Every design stage was considered, including construction, reservoir filling, and advance of saturation front until the steady-state flow condition is attained. A transient analysis of safety factors applicable to 3-dimensional conditions was presented, giving consideration to unsaturated materials and the interrelation between hydraulic and mechanical phenomena by solving equilibrium and continuity conditions at the same time. The finite element method was used to formulate equilibrium and continuity conditions for both soil skeleton and pore water, which necessitated a realistic mechanical model for the stress-strain-suction relation in unsaturated porous material and adequate constitutive models related to water flow and storage, giving special consideration to imposing appropriate boundary conditions for each simulation stage. The methodology was applied to the analysis of earth dams composed of soils at optimum, dry of optimum, and mixed compaction conditions. The dry section simulated dams constructed using poorly compacted, dry material, which are prone to collapse. By strategically placing the optimum materials in the areas of the earth fill that are most stressed, the mixed section could be designed less expensively with the same or better performance as the homogenous section at optimum conditions. The coupled analysis provides a higher safety factor than uncoupled analysis and a realistic picture of end-of-construction pore pressure distribution. The simulation of reservoir filling and saturation front advance permitted clear identification of the initialization, development, and evolution of internal failure mechanisms. 21 refs., 6 tabs., 19 figs.

    This paper aims to analyze the hydropower potential of municipal water supply dams in Turkey. The facility is in favor with the energy policy of Turkish Government and European Union. In the study, the design head of the power plant was selected as the average water level of the reservoir and the discharge was calculated from the annual water supply of the dam. It has been estimated that the existing 45 municipal water supply dams of Turkey have an electric energy potential of 173 GWh/year, corresponding to about 24,000,000 Euro/year economic benefit. The financing of these facilities can be provided from international funding institutions. For a case study, Zonguldak Ulutan Dam and its water treatment plant have been investigated in detail.

    This paper aims to analyze the hydropower potential of municipal water supply dams in Turkey. The facility is in favor with the energy policy of Turkish Government and European Union. In the study, the design head of the power plant was selected as the average water level of the reservoir and the discharge was calculated from the annual water supply of the dam. It has been estimated that the existing 45 municipal water supply dams of Turkey have an electric energy potential of 173 GWh/year, corresponding to about 24,000,000 Euro/year economic benefit. The financing of these facilities can be provided from international funding institutions. For a case study, Zonguldak Ulutan Dam and its water treatment plant have been investigated in detail. The current electricity consumption of the water treatment plant is 4,500,000 kWh/year and the facility provides 35,000 m{sup 3}/day water to 6 settlements. The installation of a hydropower plant on the mentioned water treatment plant will cut the electric consumption by 24%. The proposed project has a payback period of 1.4 years and it can produce clean and feasible energy.

    Full Text Available Introduction: We hypothesized that a geriatric chief complaint–based didactic curriculum would improve resident documentation of elderly patient care in the emergency department (ED. Methods: A geriatric chief complaint curriculum addressing the 3 most common chief complaints—abdominal pain, weakness, and falls—was developed and presented. A pre- and postcurriculum implementation chart review assessed resident documentation of the 5 components of geriatric ED care: 1 differential diagnosis/patient evaluation considering atypical presentations, 2 determination of baseline function, 3 chronic care facility/caregiver communication, 4 cognitive assessment, and 5 assessment of polypharmacy. A single reviewer assessed 5 pre- and 5 postimplementation charts for each of 18 residents included in the study. We calculated 95% confidence and determined that statistical significance was determined by a 2-tailed z test for 2 proportions, with statistical significance at 0.003 by Bonferroni correction. Results: For falls, resident documentation improved significantly for 1 of 5 measures. For abdominal pain, 2 of 5 components improved. For weakness, 3 of 5 components improved. Conclusion: A geriatric chief complaint–based curriculum improved emergency medicine resident documentation for the care of elderly patients in the ED compared with a non–age-specific chief complaint–based curriculum.

    2001-01-01

    Modernization and maintenance of a dam often require emptying the reservoir, a process that can cause mud bank instabilities and environmental disturbances. In order to address the problem of mud bank collapse characterization, a study is conducted in partnership with the Laboratoire National d'Hydraulique (LNH), a subsidiary of Electricité de France (EDF). This paper presents a geotechnical modeling of submerged and emergent mud bank stability and a comparison of the model results with the measurements carried out throughout the whole reservoir.

    In early operations at BHP-Utah's Saraji Mine in central Queensland, quantities of coking coal were pumped into the tailings dam because the preparation plant's flotation circuit was unable to handle ultra-fines. A reverse circulating drilling rig mounted on a hovercraft was used to recover 22 samples (representing 9 metres of tailings from 11 x 8 x 0.09 metre cores) in an investigation into whether the tailings can now be treated economically. 1 fig.

    High flooding downstream of a dam could cause severe damages to the people and property. The most important damage is the loss of life which does not have any substitute. In this study, the extent of loss of life (LOL) downstream of a large dam due to dam failure has been focused. The LOL extent has been considered in terms of downstream distance. For systematic hydraulic analysis, the Jhelum river valley, about 329 km long downstream of Mangla dam in Pakistan has been taken into consideratio...

  14. The evolution of gravel bed channels after dam removal: Case study of the Anaconda and Union City Dam removals

    Wildman, Laura A. S.; MacBroom, James G.

    2005-10-01

    The Anaconda and Union City Dams on the Naugatuck River in Connecticut were removed in February and October 1999. A detailed study of the sites prior to removal was undertaken including sediment testing and predictions of upstream channel formation post-dam removal. The 3.35-m-high timber crib/rock fill spillway of the Anaconda Dam partially breached during a storm prior to the dam's scheduled removal allowing a portion of the impounded sediment to move down through the river system. This event changed the removal plans and the remainder of the spillway was removed under an emergency order in the course of 4 days. The Union City Dam, a 2.44-m-high timber crib/rock fill dam capped with concrete and stone, was removed on schedule. A portion of the impounded sediment was removed by mechanical means during the deconstruction of the structure. The evolution of the two upstream channels post-project provided unique challenges and valuable insights as to what kind of channel transition can be expected in gravel bed river systems after a low head dam has been removed. This paper describes the initial engineering analysis and design, the subsequent removal of the two dams, and compares observations on the transition of the upstream channels following dam removal to the initial engineering predictions and other models. The relatively steep gravel bed channels evolved in a predictable manner, except where anthropogenic barriers (sanitary sewer, rock weir) interrupted.

  15. The World Commission on Dams + 10: Revisiting the Large Dam Controversy

    2010-06-01

    Full Text Available The World Commission on Dams (WCD was an experiment in multi-stakeholder dialogue and global governance concerned with a subject area – large dams – that was fraught with conflict and controversy. The WCD Report, Dams and Development: A New Framework for Decision-Making, was published in 2000 and accompanied by hopes that broad-based agreements would be forged on how to better manage water and energy development. Ten years later, this special issue of Water Alternatives revisits the WCD and its impacts, exploring the question: Is the WCD still relevant? The editorial team and the Guest Editors of this special issue of Water Alternatives have selected a range of 20 papers, 6 viewpoints, and 4 book reviews that help to illustrate the evolution in the dams debate. The goal of this special issue is to examine the influence and the impacts of the WCD on the dam enterprise, in general, and on the policies and practices of key stakeholders and institutions, and on the development outcomes for affected communities and environments, in particular. In this introduction, the Guest Editors provide an overview of the special issue, exploring the new drivers of dam development that have emerged during the last decade, including climate change and new financiers of dams, and describing the themes emerging from this diverse set of papers and viewpoints. This special issue demonstrates the need for a renewed multi-stakeholder dialogue at multiple levels. This would not be a redo of the WCD, but rather a rekindling and redesigning of processes and forums where mutual understanding, information-sharing, and norm-setting can occur. One of the most promising developments of the last decade is the further demonstration, in case studies described here, that true partnership amongst key stakeholders can produce transformative resource-sharing agreements, showing that many of the WCD recommendations around negotiated decision making are working in practice.

  16. Quasi-stable Slope-Failure Dams in High Asia

    Shroder, J. F.

    2010-12-01

    Collapses of steep mountain slopes in the Himalaya, Karakoram, Pamir, Hindu Kush, and Tibetan Plateau are well known as a result of:(1) generally high seismicity in active tectonic areas; (2) prior deglaciation leaving undercut, unstable cliffs; (3) present-day debuttressing of rock cliffs by glacial down-wasting in conditions of global warming; and (4) degradation of permafrost cohesion and water-ice cementation in high mountain slopes. Landslide dams across mountain rivers are also well known worldwide and generally do not endure for long because of the common landslide-lake outburst floods (LLOF) whose discharge is commonly sufficiently large to remove much of the dam in a short time. A number of massive slope-failure dams in south High Asia, however, have endured for centuries and require explanations for the length of duration, whereas recent examples require robust assessment for better predictive hazard analysis. Three main factors contribute to longevity of slope-failure dams: (1) mega-rocks >15-30 m that inhibit dam failure in overflow breaches; (2) mega-porosity wherein incoming discharge to the landslide lake is balanced by subterranean water through-flow within the landslide dam; (3) impermeable clay fills caused by remobilization of prior lacustrine-dammed sediment that impart dam strength to allow lasting integrity for a time, and (4) climate-change induced lake-level lowering. Several examples of long-lived or unusually stable, slope-failure dams associated with pronounced structural/tectonic associations include: (1) Pangong Tso, Ladakh and Tibet; (2) Lake Shewa, Afghanistan; (3) Sarez Lake, Tajikistan; and (4) Lake Hunza, Pakistan. Pangong Tso and Lake Shewa were emplaced thousands of years ago and only Lake Shewa shows some instability of the dam front where percolating water maintains lake level but may be causing new slumping. Sarez Lake behind the Usoi landslide dam was emplaced by an earthquake in 1911 and maintains its level by seepage. Lake

  17. Gypsum-karst problems in constructing dams in the USA

    Johnson, Kenneth S.

    2008-01-01

    Gypsum is a highly soluble rock and is dissolved readily to form caves, sinkholes, disappearing streams, and other karst features that typically are also present in limestones and dolomites. Gypsum karst is widespread in the USA and has caused problems at several sites where dams were built, or where dam construction was considered. Gypsum karst is present (at least locally) in most areas where gypsum crops out, or is less than 30-60 m below the land surface. These karst features can compromise on the ability of a dam to hold water in a reservoir, and can even cause collapse of a dam. Gypsum karst in the abutments or foundation of a dam can allow water to pass through, around, or under a dam, and solution channels can enlarge quickly, once water starts flowing through such a karst system. The common procedure for controlling gypsum karst beneath the dam is a deep cut-off trench, backfilled with impermeable material, or a close-spaced grout curtain that hopefully will fill all cavities. In Oklahoma, the proposed Upper Mangum Dam was abandoned before construction, because of extensive gypsum karst in the abutments and impoundment area. Catastrophic failure of the Quail Creek Dike in southwest Utah in 1989 was due to flow of water through an undetected karstified gypsum unit beneath the earth-fill embankment. The dike was rebuilt, at a cost of US 12 million, with construction of a cut-off trench 600 m long and 25 m deep. Other dams in the USA with severe gypsum-karst leakage problems in recent years are Horsetooth and Carter Lake Dams, in Colorado, and Anchor Dam, in Wyoming.

  18. Evaluation Model of Life Loss Due to Dam Failure

    Dam failure poses a serious threat to human life, however there is still lack of systematic research on life loss which due to dam failure in China. From the perspective of protecting human life, an evaluation model for life loss caused by dam failure is put forward. The model building gets three progressive steps. Twenty dam failure cases in China are preferably chosen as the basic data, considering geographical location and construction time of dams, as well as various conditions of dam failure. Then twelve impact factors of life loss are selected, including severity degree of flood, population at risk, understanding of dam failure, warning time, evacuation condition, number of damaged buildings, water temperature, reservoir storage, dam height, dam type, break time and distance from flood area to dam. And through principal component analysis, it gets four principal components consisting of the first flood character principle component, the second warning system principle component, the third human character principle component and the fourth space-time impact principle component. After multivariate nonlinear regression and ten-fold validation in combination, the evaluation model for life loss is finally established. And the result of the proposed model is closer to the true value and better in fitting effect in comparison with the results of RESCDAM method and M. Peng method. The proposed model is not only applied to evaluate life loss and its rate under various kinds of dam failure conditions in China, but also provides reliable cause analysis and prediction approach to reduce the risk of life loss.

    2005-01-01

    Based on research studies currently being carried out at Dalian University of Technology, some important aspects for the earthquake safety assessment of concrete dams are reviewed and discussed. First, the rate-dependent behavior of concrete subjected to earthquake loading is examined, emphasizing the properties of concrete under cyclic and biaxial loading conditions. Second, a modified four-parameter Hsieh-Ting-Chen viscoplastic consistency model is developed to simulate the rate-dependent behavior of concrete. The earthquake response of a 278m high arch dam is analyzed, and the results show that the strain-rate effects become noticeable in the inelastic range. Third, a more accurate non-smooth Newton algorithm for the solution of three-dimensional frictional contact problems is developed to study the joint opening effects of arch dams during strong earthquakes. Such effects on two nearly 300m high arch dams have been studied. It was found that the canyon shape has great influence on the magnitude and distribution of the joint opening along the dam axis. Fourth, the scaled boundary finite element method presented by Song and Wolf is employed to study the dam-reservoir-foundation interaction effects of concrete dams. Particular emphases were placed on the variation of foundation stiffness and the anisotropic behavior of the foundation material on the dynamic response of concrete dams. Finally, nonlinear modeling of concrete to study the damage evolution of concrete dams during strong earthquakes is discussed. An elastic-damage mechanics approach for damage prediction of concrete gravity dams is described as an example. These findings are helpful in understanding the dynamic behavior of concrete dams and promoting the improvement of seismic safety assessment methods.

    Pierre-Joseph Macquer (1718-1784) is well known as one of the major chemists in the eighteenth century as a theoretician and a teacher. He is also known for his works on dyeing. This paper presents a new face of Macquer. He proposed a theory on mordants in dyeing as early as 1775. Besides his activity at the Académie des sciences, he played an important role in Government as the commissioner of dyeing from 1766 where he established close links with artisan inventors. Académicien chimiste at the royal Manufactory of Sèvres from 1757, he was also the inventor of French porcelain. His notebooks show his organization, method, courage, passion and obstinacy in the search for the paste for hard porcelain. He also proposed an interpretation of its formation. Macquer was both a theoretician and a practical expert in dyeing as well as in porcelain making. He managed to bridge the gap between science and art.

    A 76-year-old female presented to our hospital with a 2 cm firm, nontender, protuberant umbilical nodule. She received treatment with antibiotics for suspected granuloma, with no improvement after two months. High levels of CA125 as well as an ovarian cyst and intrathoracic and intra-abdominal lesions on imaging studies made us suspect an ovarian cancer with a Sister Mary Joseph nodule (SMJN) and other metastases. A bilateral salpingo-oophorectomy and umbilical and omentum tumor resections were performed and a metastatic ovarian serous adenocarcinoma was diagnosed by histopathology. After surgery, the patient received chemotherapy with paclitaxel, carboplatin, and bevacizumab; however paclitaxel allergy was observed. As a result, chemotherapy continued with carboplatin and bevacizumab every three weeks for a total of 6 courses. Currently, she is still undergoing treatment with bevacizumab and CA125 levels have been progressively decreasing. SMJN is a rare umbilical metastasis which needs to be considered as a differential diagnosis in the presence of an umbilical tumor for prompt treatment initiation.

    The career of Joseph Jastrow (1863-1944) spanned more than 50 years in service to psychology. For 40 years he represented academic psychology at the University of Wisconsin as chair of the psychology department (1886 to 1927), but also was never far from popularizing psychology through books, articles, public lectures, newspaper columns, and finally radio lectures (e.g., Jastrow, 1900, 1935b). Providing a scientific and progressive psychology for the general public was always a strong penchant for Jastrow on several subjects, such as spiritualism (Jastrow, 1911) and effective living (Jastrow, 1935b). About 1939, while he was well into his 70s, his efforts focused on exposing the menace that Adolf Hitler and Nazism posed, so he undertook to enlist prominent editors to publish his work, Hitler: Mask and Myth, as articles or a book. He was not successful in gaining support for the project. His failing can be understood from the perspectives of the American market for Hitler material, the shortcomings of the manuscript, and how he represented psychology to the American public.

    2007 was a year of progress and challenges for the Office of the Chief Financial Officer (OCFO). I believe that with the addition of a new Controller, the OCFO senior management team is stronger than ever. With the new Controller on board, the senior management team spent two intensive days updating our strategic plan for the next five years ending in 2012, while making sure that we continue to execute on our existing strategic initiatives. In 2007 the Budget Office, teaming with Human Resources, worked diligently with our colleagues on campus to reengineer the Multi-Location Appointment (MLA) process, making it easier for our Principal Investigators (PIs) to work simultaneously between the Laboratory and UC campuses. The hiring of a point-of-contact in Human Resources to administer the program will also make the process flow smoother. In order to increase our financial flexibility, the OCFO worked with the Department of Energy (DOE) to win approval to reduce the burden rates on research and development (R&D) subcontracts and Intra-University Transfers (IUT). The Budget Office also performed a 'return on investment' (ROI) analysis to secure UCRP funding for a much needed vocational rehabilitation counselor. This new counselor now works with employees who are on medical leave to ensure that they can return to work in a more timely fashion, or if not able to return, usher them through the various options available to them. Under the direction of the new Controller, PriceWaterhouse Coopers (PWC) performed their annual audit of the Laboratory's financial data and reported positive results. In partnership with the Financial Policy and Training Office, the Controller's Office also helped to launch self-assessments of some of our financial processes, including timekeeping and resource adjustments.

This was the first time in almost a decade that the financial operations of the Laboratory had been reviewed. The Committee relayed their observations on our strengths, and their very thoughtful recommendations for improvement, which we are actively pursuing. These improvements, when implemented, will benefit the entire Laboratory for many years to come. The complete report is available on the OCFO website (www.lbl.gov/Workplace/CFO). In August, the senior management team of the OCFO participated in a strategic planning retreat. The purpose of the two and a half day exercise was, of course, to update our strategic plan, but instead of spending days developing a written document, we enlisted the expertise of a seasoned journalist who also happens to be a very talented graphic artist. He listened carefully to our ideas and committed them to a visual roadmap. All members of the OCFO, Business Managers, and the Laboratory Leadership Team reviewed this draft roadmap. By having a completely visual strategic plan that is posted widely throughout the OCFO, all employees can easily see and identify with the goals that we are all working towards. FY2010 was an extraordinary year. The Laboratory welcomed its seventh Director, Dr. Paul Alivisatos, who wasted no time communicating his vision and priorities for Berkeley Lab. They include five very ambitious initiatives: Carbon Cycle 2.0, The Next Generation Light Source, a Safe and Efficient Lab, Building Community, and Space. In response, the Office of the Chief Financial Officer (OCFO) developed twelve specific initiatives that align completely with these five priorities.

    Rounds, Stewart A.

    2010-01-01

    Methods were developed to assess the effects of dams on streamflow and water temperature in the Willamette River and its major tributaries. These methods were used to estimate the flows and temperatures that would occur at 14 dam sites in the absence of upstream dams, and river models were applied to simulate downstream flows and temperatures under a no-dams scenario. The dams selected for this study include 13 dams built and operated by the U.S. Army Corps of Engineers (USACE) as part of the Willamette Project, and 1 dam on the Clackamas River owned and operated by Portland General Electric (PGE). Streamflows in the absence of upstream dams for 2001-02 were estimated for USACE sites on the basis of measured releases, changes in reservoir storage, a correction for evaporative losses, and an accounting of flow effects from upstream dams. For the PGE dam, no-project streamflows were derived from a previous modeling effort that was part of a dam-relicensing process. Without-dam streamflows were characterized by higher peak flows in winter and spring and much lower flows in late summer, as compared to with-dam measured flows. Without-dam water temperatures were estimated from measured temperatures upstream of the reservoirs (the USACE sites) or derived from no-project model results (the PGE site). When using upstream data to estimate without-dam temperatures at dam sites, a typical downstream warming rate based on historical data and downstream river models was applied over the distance from the measurement point to the dam site, but only for conditions when the temperature data indicated that warming might be expected. Regressions with measured temperatures from nearby or similar sites were used to extend the without-dam temperature estimates to the entire 2001-02 time period. Without-dam temperature estimates were characterized by a more natural seasonal pattern, with a maximum in July or August, in contrast to the measured patterns at many of the tall dam sites

    Issues regarding building large-scale dams as a solution to power generation and flood control problems have been widely discussed by both natural and social scientists from various disciplines, as well as the policy-makers and public. Since the Chinese government officially approved the Three Gorges Dam (TGD) projects, this largest hydroelectric project in the world has drawn a lot of debates ranging from its social and economic to climatic impacts. The TGD has been partially in use since June 2003. The impact of the TGD is examined through analysis of the National Aeronautics and Space Administration (NASA) Tropical Rainfall Measuring Mission (TRMM) rainfall rate and Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature and high-resolution simulation using the Pennsylvania State University-National Center for Atmospheric Research (PSU-NCAR) fifth-generation Mesoscale Model (MM5). The independent satellite data sets and numerical simulation clearly indicate that the land use change associated with the TGD construction has increased the precipitation in the region between Daba and Qinling mountains and reduced the precipitation in the vicinity of the TGD after the TGD water level abruptly rose from 66 to 135 m in June 2003. This study suggests that the climatic effect of the TGD is on the regional scale (approx.100 km) rather than on the local scale (approx.10 km) as projected in previous studies.

  11. Dynamic decision making for dam-break emergency management – Part 2: Application to Tangjiashan landslide dam failure

    Full Text Available Tangjiashan landslide dam, which was triggered by the Ms = 8.0 Wenchuan earthquake in 2008 in China, threatened 1.2 million people downstream of the dam. All people in Beichuan Town 3.5 km downstream of the dam and 197 thousand people in Mianyang City 85 km downstream of the dam were evacuated 10 days before the breaching of the dam. Making such an important decision under uncertainty was difficult. This paper applied a dynamic decision-making framework for dam-break emergency management (DYDEM to help rational decision in the emergency management of the Tangjiashan landslide dam. Three stages are identified with different levels of hydrological, geological and social-economic information along the timeline of the landslide dam failure event. The probability of dam failure is taken as a time series. The dam breaching parameters are predicted with a set of empirical models in stage 1 when no soil property information is known, and a physical model in stages 2 and 3 when knowledge of soil properties has been obtained. The flood routing downstream of the dam in these three stages is analyzed to evaluate the population at risk (PAR. The flood consequences, including evacuation costs, flood damage and monetized loss of life, are evaluated as functions of warning time using a human risk analysis model based on Bayesian networks. Finally, dynamic decision analysis is conducted to find the optimal time to evacuate the population at risk with minimum total loss in each of these three stages.

    Attempting to play the role of King Solomon in his PPACA decision, Chief Justice John Roberts split the baby perversely by ruling it was not a tax under the Anti-Injunction Act, which would have likely deprived the Court of jurisdiction to hear this pre-enforcement challenge to the individual mandate, but it was a tax for taxing and spending purposes even though Congress said it was a "penalty" and not a tax. And the Chief Justice had to twist further his "wisdom" to hold that it was not an unconstitutional direct tax, even though that is exactly what it is, if it is a tax in the first instance.

    Among the difficulties that influence future dam operations, reservoir sedimentation is the most problematic for engineers. This study predicted the amount and pattern of sedimentation for use in estimation of the useful lifespan of reservoirs and identification of optimal locations for outlets and intakes at the initial stages of dam design. Hydrographic surveys of different dams can provide better insight into this phenomenon. Latian Dam in Iran has conducted hydrographic surveys during 7 time periods. The amount and process of sedimentation in this reservoir were determined, and predictions of distribution of sediments were validated by well-known, common methods. The formation of a delta in the reservoir was investigated for different time periods after operation. Future problems due to the impacts of sedimentation on dam operation and the useful lifespan of the reservoir were predicted. In addition, the study results may be used for developing empirical methods to predict sedimentation patterns in other reservoirs.

    The Papan dam in the Krygyz Republic is 97 metres high. It is located in the Osh Oblast, within a narrow and steep sided gorge on the Ak-Bura River, approximately 20 kilometres south of the City of Osh. The impoundment of the dam revealed large inflows of water to the downstream dam through the upper half of the dam and through the joints in the right abutment. A number of options were considered before a treatment method was selected. The causes of the leakage were poor grouting, and joints and fissures in the abutment. The remedial process involved the use of a plastic concrete cutoff wall extended from the crest of the dam to a depth of approximately 70 metres, in addition to the use of a grouting curtain in the right abutment. 2 figs.

    Oswell, Terry [BC Hydrom Burnaby, (Canada)

    2010-07-01

    BC Hydro has a wide range of dams, which raises a wide range of issues at many unique sites. A dam safety database was developed in 2000 to deal with the complexity and volume of information provided by deficiency investigations and surveillances. The database contains all documented deficiencies and non-conformances identified in the past 10 years. It records the risk ratings assigned to each issue. This paper described the implementation of the database tool, from the characterization of a dam safety issue to the use of the database itself. The dam safety database is now a key tool in managing the dam safety program at BC Hydro and has been useful for the last 10 years or so in prioritizing the program of deficiency investigations and capital projects. The development of a process to rate non-conformances is currently under study and will be implemented soon to aid in more efficient prioritization of maintenance activities.

    Glaciers are extensively developed in the southwest of Tibet and the moraines are widely distributed with large depth. Large-scale debris flows are often reported which blocked rivers and formed dams. In this paper, seven large debris flows in four valleys are discussed, among which five dams developed. 13 sets of experiments have been conducted in laboratory to simulate the formation and failure of the dam. Finally, a model of dam failure is proposed and a formula is established to calculate the flood discharge:Q = kbhhk/T (B)/LG0.41, where bk is the outlet width of the dam atthe original water level, ht the erosive depth, T the time fromoverflow to final state of failure, the average width of lake; L thelength of the lake, and G the total potential energy of the water inthe lake.

  9. Channel evolution on the dammed Elwha River, Washington, USA

    2011-01-01

    Like many rivers in the western U.S., the Elwha River, Washington, has changed substantially over the past century in response to natural and human forcing. The lower river is affected by two upstream dams that are slated for removal as part of a major river restoration effort. In preparation for studying the effects of dam removal, we present a comprehensive field and aerial photographic analysis of dam influence on an anabranching, gravel-bed river. Over the past century with the dams in place, loss of the upstream sediment supply has caused spatial variations in the sedimentary and geomorphic character of the lower Elwha River channel. Bed sediment is armored and better sorted than on the naturally evolving bed upstream of the dams. On time scales of flood seasons, the channel immediately below the lower dam is fairly stable, but progresses toward greater mobility downstream such that the lowermost portion of the river responded to a recent 40-year flood with bank erosion and bed-elevation changes on a scale approaching that of the natural channel above the dams. In general, channel mobility in the lowest 4 km of the Elwha River has not decreased substantially with time. Enough fine sediment remains in the floodplain that – given sufficient flood forcing – the channel position, sinuosity, and braiding index change substantially. The processes by which this river accesses new fine sediment below the dams (rapid migration into noncohesive banks and avulsion of new channels) allow it to compensate for loss of upstream sediment supply more readily than would a dammed river with cohesive banks or a more limited supply of alluvium. The planned dam removal will provide a valuable opportunity to evaluate channel response to the future restoration of natural upstream sediment supply.

  10. Geophysical Investigations at Hidden Dam, Raymond, California Flow Simulations

    Minsley, Burke J.; Ikard, Scott

    2010-01-01

    Numerical flow modeling and analysis of observation-well data at Hidden Dam are carried out to supplement recent geophysical field investigations at the site (Minsley and others, 2010). This work also is complementary to earlier seepage-related studies at Hidden Dam documented by Cedergren (1980a, b). Known seepage areas on the northwest right abutment area of the downstream side of the dam was documented by Cedergren (1980a, b). Subsequent to the 1980 seepage study, a drainage blanket with a sub-drain system was installed to mitigate downstream seepage. Flow net analysis provided by Cedergren (1980a, b) suggests that the primary seepage mechanism involves flow through the dam foundation due to normal reservoir pool elevations, which results in upflow that intersects the ground surface in several areas on the downstream side of the dam. In addition to the reservoir pool elevations and downstream surface topography, flow is also controlled by the existing foundation geology as well as the presence or absence of a horizontal drain in the downstream portion of the dam. The current modeling study is aimed at quantifying how variability in dam and foundation hydrologic properties influences seepage as a function of reservoir stage. Flow modeling is implemented using the COMSOL Multiphysics software package, which solves the partially saturated flow equations in a two-dimensional (2D) cross-section of Hidden Dam that also incorporates true downstream topography. Use of the COMSOL software package provides a more quantitative approach than the flow net analysis by Cedergren (1980a, b), and allows for rapid evaluation of the influence of various parameters such as reservoir level, dam structure and geometry, and hydrogeologic properties of the dam and foundation materials. Historical observation-well data are used to help validate the flow simulations by comparing observed and predicted water levels for a range of reservoir elevations. The flow models are guided by, and

  11. Estimating Snow Budget of Karaj Dam Reservoir

    Directory of Open Access Journals (Sweden)

    Manijeh G. Tali

    2009-01-01

    Full Text Available Problem statement: Most of the cold period precipitation of Karaj Basin falls in the form of snow. This snow and its run off are important to the dam and the local needs such as agriculture and the drinking water of Tehran. But due to the scarcity and in some elevations the lack of weather stations, measuring this snow cover and its run off is difficult. We have decided to estimate the amount of this snow cover by using surrogate methods such as satellite images of MODIS and temperature thresholds. Approach: To estimate the snow water budget of the Karaj Dam Reservoir Basin, first a temperature threshold of 3° Celsius was defined according to the analysis of daily temperature and precipitation values of Nesa station during 1960-2000. The elevation of this temperature was as low as 1590 m in February and 5734 m in August. During each month the melting snow was computed over the area between 3 and zero degrees Celsius and precipitation below zero degrees was considered as permanent snow cover. The precipitation of areas above 3° was computed as rain. Using this temperature threshold and the DEM map of the basin we estimated the snow cover and snow melt water of the basin. The snow cover area on the MODIS images was estimated and compared with that computed from temperature threshold. Both methods gave relatively similar results. At the end the snow melt water of the whole cold period was calculated and added up to estimate the total snow water budget. Results: The results showed that during the study months most (67.7% of the precipitation comes in the form of snow. And most of this snow (97.5% melts during months March and onward. Its monthly distributions are 3.8% in March, 22.7% in April and 71% in May. The total snow water entering the dam was about 181.73 million cubic meters. Conclusion: The comparison of the results from temperature thresholds with the MODIS images snow cover showed very little and negligible discrepancy. Therefore, this

    Full Text Available Given the opportunities offered by foreign investment in energy infrastructure mostly by Chinese firms, the Government of Cambodia is giving high priority to developing hydropower resources for reducing energy poverty and powering economic growth. Using a “Political ecology of the Asian drivers” framework, this paper assesses China’s involvement in the development of large dams’ in Cambodia and its impacts on the access of natural resources such as water and energy by dam builders, local communities and the government. This analysis is based on 61 interviews and 10 focus group discussions with affected communities, institutional actors, Chinese dam builders and financiers in relation to the first large Chinese dam built in Cambodia: the Kamchay dam. Based on the results of the analysis this paper makes recommendations on how to improve the planning, implementation and governance of future large dams in Cambodia.

    This paper discussed the methods used to assess the safety of dams constructed at Syncrude's mining facilities in Fort McMurray, Alberta. It also proposed recommendations for improvements and additions to the Canadian Dam Safety Guidelines that consider the unique and demanding requirements for assessing dam safety in a mining environment. Mining structures are very diverse, ranging from conventional dams that retain diverted water from the mine site, to tailings dykes that retain pond fluids. Some structures are modified mine dumps composed of loose fill that present challenges to the design engineer. Most of these structures are built over a long period of time, and as such are subjected to several design revisions because of tailings disposal plans and the availability of material. Performance monitoring is needed to anticipate failure and evaluate the potential consequences of dam failure. 4 refs.

    The movements and dam passage of juvenile Chinook salmon implanted with acoustic transmitters and passive integrated transponder tags were studied at Cougar Reservoir and Dam, near Springfield, Oregon. The purpose of the study was to provide information to aid with decisions about potential alternatives for improving downstream passage conditions for juvenile salmonids in this flood-control reservoir. In 2011, a total of 411 hatchery fish and 26 wild fish were tagged and released during a 3-month period in the spring, and another 356 hatchery fish and 117 wild fish were released during a 3-month period in the fall. A series of 16 autonomous hydrophones throughout the reservoir and 12 hydrophones in a collective system near the dam outlet were used to determine general movements and dam passage of the fish over the life of the acoustic transmitter, which was expected to be about 3 months. Movements within the reservoir were directional, and it was common for fish to migrate repeatedly from the head of the reservoir downstream to the dam outlet and back to the head of the reservoir. Most fish were detected near the temperature control tower at least once. The median time from release near the head of the reservoir to detection within about 100 meters of the dam outlet at the temperature control tower was between 5.7 and 10.8 days, depending on season and fish origin. Dam passage events occurred over a wider range of dates in the spring and summer than in the fall and winter, but dam passage numbers were greatest during the fall and winter. A total of 10.5 percent (43 of 411) of the hatchery fish and 15.4 percent (4 of 26) of the wild fish released in the spring are assumed to have passed the dam, whereas a total of 25.3 percent (90 of 356) of the hatchery fish and 16.9 percent (30 of 117) of the wild fish released in the fall are assumed to have passed the dam. A small number of fish passed the dam after their transmitters had stopped working and were detected at

    Floods occurring in the 1980s and 1990s have caused many governments to explore methods of ensuring dam safety. The government of Quebec has recently established security regulations for dams using a classification system that requires engineering studies for dams. The security studies require hydrological and hydraulic analyses of all dam structures. This paper discussed case studies of concrete and earth-filled dams located in Quebec and made in relation to the new dam safety regulations. The studies demonstrated that dam safety is often impacted by a lack of information related to the dam's underlying geology. Construction plans are not available for many older dams. The results obtained from numerical analyses must be rigorously analyzed as they often present simplistic solutions to complicated issues. It was concluded that a number of steps must be followed in relation to both the dam and its surrounding environment in order to ensure dam safety. 11 refs., 3 tabs., 5 figs.

    The cerebellum is no longer considered a purely motor control device, and convincing evidence has demonstrated its relationship to cognitive and emotional neural circuits. The aims of the present study were to establish the core cognitive features in our patient population and to determine the presence of Cerebellar Cognitive Affective Syndrome (CCAS) in this group. We recruited 38 patients with spinocerebellar ataxia type 3 (SCA3) or Machado–Joseph disease (MJD)-SCA3/MJD and 31 controls. Data on disease status were recorded (disease duration, age, age at onset, ataxia severity, and CAG repeat length). The severity of cerebellar symptoms was measured using the International Cooperative Ataxia Rating Scale and the Scale for the Assessment and Rating of Ataxia. The neuropsychological assessment consisted of the Mini-Mental State Examination, Clock Drawing Test, Wechsler Adult Intelligence Scale, Rey–Osterrieth Complex Figure, Wisconsin Card Sorting Test, Stroop Color–Word Test, Trail-Making Test, Verbal Paired Associates, and verbal fluency tests. All subjects were also submitted to the Hamilton Anxiety Scale and Beck Depression Inventory. After controlling for multiple comparisons, spatial span, picture completion, symbol search, Stroop Color–Word Test, phonemic verbal fluency, and Trail-Making Tests A and B were significantly more impaired in patients with SCA3/MJD than in controls. Executive and visuospatial functions are impaired in patients with SCA3/MJD, consistent with the symptoms reported in the CCAS. We speculate on a possible role in visual cortical processing degeneration and executive dysfunction in our patients as a model to explain their main cognitive deficit. PMID:21975858

    Full Text Available Machado-Joseph disease (MJD is an autosomal dominant, late-onset neurological disorder and the most common form of spinocerebellar ataxia (SCA worldwide. Diagnostic genetic testing is available to detect the disease-causing mutation by direct sizing of the CAG repeat tract in the ataxin 3 gene. Presymptomatic testing (PST can be used to identify persons at risk of developing the disease. Genetic counseling provides patients with information about the disease, genetic risks, PST, and the decision-making process. In this study, we present the protocol used in PST for MJD and the relevant observations from two centers: Brazil (Porto Alegre and Portugal (Porto. We provide a case report that illustrates the significant ethical and psychological issues related to PST in late-onset neurological disorders. In both centers, counseling and PST are performed by a multidisciplinary team, and genetic testing is conducted at the same institutions. From 1999 to 2012, 343 individuals sought PST in Porto Alegre; 263 (77% of these individuals were from families with MJD. In Porto, 1,530 individuals sought PST between 1996 and 2013, but only 66 (4% individuals were from families with MJD. In Brazil, approximately 50% of the people seeking PST eventually took the test and received their results, whereas 77% took the test in Portugal. In this case report, we highlight several issues that might be raised by the consultand and how the team can extract significant information. Literature about PST testing for MJD and other SCAs is scarce, and we hope this report will encourage similar studies and enable the implementation of PST protocols in other populations, mainly in Latin America.
