    1997-03-01

    The primary objective of this working group is to identify major technical, regulatory, and environmental issues that are relevant to the abandonment of offshore wellbores. Once the issues have been identified, the working group also has the objective of making recommendations or providing potential solutions for consideration. Areas for process improvement will be identified and {open_quotes}best practices{close_quotes} will be discussed and compared to {open_quotes}minimum standards.{close_quotes} The working group will primarily focus on wellbore abandonment in the Gulf of Mexico. However, workshop participants are encouraged to discuss international issues which may be relevant to wellbore abandonment practices in the Gulf of Mexico. The Abandoning Wells Group has identified several major areas for discussion that have concerns related to both operators and service companies performing wellbore abandonments in the Gulf of Mexico. The following broad topics were selected for the agenda: (1) MMS minimum requirements and state regulations. (2) Co-existence of best practices, new technology, and P & A economics. (3) Liability and environmental issues relating to wellbore abandonment.

  2. How to find abandoned oil and gas wells

    Johnston, K.H.; Carroll, H.B.; Heemstra, R.J.; Armstrong, F.E.

    1973-01-01

    This guide was written to furnish the coal industry with a description of techniques, instruments, and clues on how to find abandoned oil and gas wells that have penetrated coal seams. The report includes specific information on searching techniques currently in use by several coal mining companies, gas-transmission companies, and waterflood operators, as well as information on State agencies responsible for the enforcement of laws and the preservation and distribution of data pertaining to the drilling, development, and abandonment of oil and gas wells. Comparative tests were performed with several commercial electronic metal detectors to determine the feasibility of using them to aid in the search for abandoned wells and to determine the instrument most suited for that particular use. The role of methane detectors to locate abandoned wells is described, including a case history. Tests were made to develop an efficient procedure to follow in systematically searching an area for metallic clues or hydrocarbon evidence to abandoned wells. The guide describes, in detail, a search sequence, including the collection of basic data, preparation of the selected area, and the physical search. Methods are given for evaluating the results.

  3. Abandoning pipelines working group regulatory issues

    1997-03-01

    The history of hydrocarbon development in Louisiana and off its coast is one of the interdependence of technological innovation, entrepreneurial risk-taking, resource management, judicial decisions, legislation, marketing, employee good will, infrastructure and support services, coupled with favorable geologic structures that made early exploration and development relatively easy. Mariners sailing off the coast of Louisiana and Texas in the 1600`s recorded one of the earliest known natural oil seeps. They shrugged it off as unimportant, as there was no market for the substance they witnessed. The seepage, however, provided a tiny clue to the vast storehouse of hydrocarbons trapped in the earth`s crust extending from the uplands, through Louisiana`s swamps and marshes, and into the subaqueous habitats of the Gulf of Mexico-the world`s ninth largest body of water. In all cases, each move into a new geographic province required considerable change in operation philosophy and in the science supporting the exploration and development activity. As technology changed, or was developed to meet the industry`s needs, new frontiers were explored. However, with time-as is the case with any nonrenewable resource-fields and wells lost their productive life. They had to be abandoned. In fact, the Minerals Management Service suggests that within the next 10 years the offshore industry will remove 150 platforms per year, or nearly half of the current number of production units. The industry will be asked to dispose of nearly one unit every 2.4 days. If this is the case, abandonment issues are going to continue to surface.

  4. Assessment of environmental implications of abandoned oil and gas wells

    A detailed study was made of the potential for abandoned oil and gas wells in the Lower Tuscaloosa sand of Mississippi and Louisiana to act as conduits for movement of saline water from the Lower Tuscaloosa into underground sources of drinking water (USDW's). Finite-difference numerical modeling determined the extent that water might be forced from the Lower Tuscaloosa sand into a USDW as a result of injection into the Lower Tuscaloosa. Within the range of conditions modeled, water from the Lower Tuscaloosa never traveled into a USDW. On the basis of the modeling, the authors concluded that it is unlikely that abandoned oil and gas wells in the Lower Tuscaloosa would serve as conduits for water movement from the trend into a USDW. The procedures developed in this study should be readily applicable to analysis of the potential for abandoned wells to act as pathways for contaminant flow into USDW's in other oil and gas producing areas of the country

  7. Television method of controlling stowing of abandoned workings

    Zimny, W.

    1978-01-01

    This method describes a method of monitoring stowing of an underground abandoned working by means of a television camera lowered through a drillhole from the surface. The method was used in Poland for the first time in the period from 1974 to 1976. The camera had been previously used to check the technical state of underground sewage systems. The sAV 18 camera can be lowered to a maximum depth of 400 m, it is explosion proof and can be used under conditions of explosion hazard. A scheme of the equipment is given. A method of determining size of old workings using the camera (with light source) is explained. Examples of photos made by the camera (on videotape) of the abandoned working being stowed with a sand-water mixture through a drillhole from the surface are also given. (In Polish)

    Recent studies indicate that greenhouse gas emission inventories are likely missing methane emission sources. We conducted the first methane emission measurements from abandoned oil and gas wells and found substantial emissions, particularly from high-emitting abandoned wells. These emissions are not currently considered in any emissions inventory. We scaled methane emissions from our direct measurements of abandoned wells in Pennsylvania and calculate that they represent 4–7% of current tota...

  10. Technical standardization of oil well abandonment: a review of current standards and technologies

    Suzart, J. Walter P.; Pessoa, Laudemar; Paiva, Maria [Halliburton Energy Services (HES), Duncan, OK (United States)

    2008-07-01

    The objective of this study is to provide a new methodology for well abandonment. This practice is becoming more and more important because of the increasing number of production fields being abandoned. We strongly recommend a study of cement slurries properties for specific use in temporary and permanent abandonment plugs based on the estimation of the cement slurry hardened when placed in the well. By using specific additives, it is possible to achieve very stable slurries. For example, when permeability is reduced, formation fluid migration can be blocked and chemical reactions between the fluid and the slurry may be inhibited. With this objective, we present a laboratory investigation model and an example of slurry testing recommendation. During the abandonment operation, all records of the well characteristics should be maintained to include the reason for the abandonment, and location of fresh water, brine, and hydrocarbon zones that may exist. This documentation will also allow the analysis of solutions for the problems that originally caused the abandonment of the well. This data could be important for future use by environmental protection commissions to reopen or to drill an adjacent well. Given the high price of oil, it may now be economically feasible to reopen the well, if the reason for abandonment was low productivity. This way, a critical analysis of the current conditions of well and field abandonment in the country is presented. Based on this information, a review of the current standards is suggested. (author)

  12. Numerical Simulation of Abandoned Gob Methane Drainage through Surface Vertical Wells.

    Wei Qin

    Full Text Available The influence of the ventilation system on the abandoned gob weakens, so the gas seepage characteristics in the abandoned gob are significantly different from those in a normal mining gob. In connection with this, this study physically simulated the movement of overlying rock strata. A spatial distribution function for gob permeability was derived. A numerical model using FLUENT for abandoned gob methane drainage through surface wells was established, and the derived spatial distribution function for gob permeability was imported into the numerical model. The control range of surface wells, flow patterns and distribution rules for static pressure in the abandoned gob under different well locations were determined using the calculated results from the numerical model.

  13. Fiscal year 1995 well plugging and abandonment program Y-12 Plant, Oak Ridge, Tennessee

    This report is a synopsis of the progress of the well plugging and abandonment program at the Y-12 Plant, Oak Ridge, Tennessee, from September 1994 through August 1995. A total of 67 wells, piezometers, and borings were plugged and abandoned during the period of time covered in this report. All wells and borings were plugged and abandoned if (1) its construction did not meet current standards (substandard construction); (2) it was irreparably damaged or had deteriorated beyond practical repair; (3) its location interfered with or otherwise impeded site operations, construction, or closure activities; or (4) special circumstances existed as defined on a case-by-case basis and approved by the Y-12 Plant Groundwater Protection Program (GWPP) Manager. This summary report contains: general geologic setting of the Y-12 Plant and vicinity; discussion of well plugging and abandonment methods, grouting procedures, and waste management practices (a Waste Management Plan for Drilling Activities is included in Appendix C); summaries of plugging and abandonment activities at each site; and quality assurance/quality control (QA/QC) and health and safety protocols used during the FY 1995 Plugging and Abandonment Program

  14. Basic Data Report for Well Plugging and Abandonment and Reconfiguration Activities for Fiscal Year 2005

    The FY 2005 program was initiated on March 31, 2005, and concluded on July 16, 2005. The FY 2005 program initially included 25 wells requiring workover (P and A, Magenta reconfiguration, cleaning and keeping). During the process, the U.S. Bureau of Land Management (BLM) requested transfer of two wells (H-7c and H-8c) to their ownership for future livestock watering. These wells were transferred to the BLM through execution of Form wr-03, Declaration of Owner of Underground Water Rights, between the New Mexico Office of the State Engineer (NMOSE), the BLM, and the DOE Carlsbad Field Office (CBFO). One well (H-2b2) was cleaned and retained as a Culebra monitor well for continued use. One well (H-3d) was converted to a shallow well to monitor the formational contact between the Dewey Lake Redbeds Formation and the Santa Rosa Formation in support of the DP-831 discharge permit monitoring program. Nine dual-completion wells were reconfigured as Magenta-only monitor wells, and 12 wells were plugged and abandoned permanently. This report presents the summary in the same order that the wells were worked in the field.

  16. Practical Methods for Locating Abandoned Wells in Populated Areas

    Veloski, G.A.; Hammack, R.W.; Lynn, R.J.

    2007-09-01

    An estimated 12 million wells have been drilled during the 150 years of oil and gas production in the United States. Many old oil and gas fields are now populated areas where the presence of improperly plugged wells may constitute a hazard to residents. Natural gas emissions from wells have forced people from their houses and businesses and have caused explosions that injured or killed people and destroyed property. To mitigate this hazard, wells must be located and properly plugged, a task made more difficult by the presence of houses, businesses, and associated utilities. This paper describes well finding methods conducted by the National Energy Technology Laboratory (NETL) that were effective at two small towns in Wyoming and in a suburb of Pittsburgh, Pennsylvania.

  17. Early oil well drilling equipment and production practices. [Information helpful in locating abandoned well sites by identification of discarded parts: such abandoned wells are potential hazards in coal mining

    Johnston K.H.; Heemstra, R.J.; Armstrong, F.E.

    1976-01-01

    A detailed description of early-day cable tool drilling rig construction and drilling practices is presented. Intimate descriptions of various parts of drilling rigs and prime movers are given as to materials of construction as well as to their use. The body of material is broken down into two main categories: well drilling methods, and well completion and production methods. This information is largely directed to the need for locating abandoned wellsites by identification of equipment parts and layouts. These abandoned wells are potential hazards to people in the coal industry if they intersect coal seams under development. The material is well illustrated from documented sources and general nomenclature is given.

    2011-01-01

    Full Text Available Abstract Background The care and protection of the estimated 143,000,000 orphaned and abandoned children (OAC worldwide is of great importance to global policy makers and child service providers in low and middle income countries (LMICs, yet little is known about rates of child labour among OAC, what child and caregiver characteristics predict child engagement in work and labour, or when such work infers with schooling. This study examines rates and correlates of child labour among OAC and associations of child labour with schooling in a cohort of OAC in 5 LMICs. Methods The Positive Outcomes for Orphans (POFO study employed a two-stage random sampling survey methodology to identify 1480 single and double orphans and children abandoned by both parents ages 6-12 living in family settings in five LMICs: Cambodia, Ethiopia, India, Kenya, and Tanzania. Regression models examined child and caregiver associations with: any work versus no work; and with working Results The majority of OAC (60.7% engaged in work during the past week, and of those who worked, 17.8% (10.5% of the total sample worked 28 or more hours. More than one-fifth (21.9%; 13% of the total sample met UNICEF's child labour definition. Female OAC and those in good health had increased odds of working. OAC living in rural areas, lower household wealth and caregivers not earning an income were associated with increased child labour. Child labour, but not working fewer than 28 hours per week, was associated with decreased school attendance. Conclusions One in seven OAC in this study were reported to be engaged in child labour. Policy makers and social service providers need to pay close attention to the demands being placed on female OAC, particularly in rural areas and poor households with limited income sources. Programs to promote OAC school attendance may need to focus on the needs of families as well as the OAC.

  19. Remediation of the Old Ecological Load in the Protected Area of the Morava River – Re-abandonment of the Oil and Gas Production Wells

    Petr Bujok

    2015-06-01

    Full Text Available The presence of the former oil and gas producing wells that are or can be improperly abandoned creates a possible environmental hazard in terms of contamination of the groundwater and soil in the present. In the area of the Czech Republic, specifically in South Moravia part, which has a long oil and gas production history, plenty of such wells can be found. Finding out the information about their abandonment in archives is often very demanding (sometimes even impossible. During various survey works and re-abandonment attempts it was found out that many wells are originally abandoned improperly, insufficiently or not at all. The occurrence of such wells is not just potential but also very actual hazard for the cultural landscape of the South Moravia, especially for aquifers, agriculture and natural protected areas of national significance. This paper is focused on the possibility of the definitive abandonment of this particular ecological load. The proposed method was verified in laboratory conditions and in the field. It is now a standard form of the re abandonment of oil and gas wells without precise localization in the South Moravian oil fields.

    Abandoned (no longer operated), Orphaned (abandoned and responsible party unavailable), and/or Lost (location unknown, cannot be confirmed, or not on record) (AOL) wells provide a potential pathway for subsurface migration, and emissions to the atmosphere, of methane and other volatile hydrocarbons. However, little is known about methane fluxes from AOL wells. Of the 12,000 abandoned and orphaned oil and gas wells on the Pennsylvania Department of Environmental Protection's (PA DEP) list, 36% are in McKean County. McKean County is home to the Bradford Oil Field, the world's first large oil field, which in 1881 produced 83% of America's output. A large fraction of the oil and gas wells in McKean County are AOL and some estimates of the number of AOL wells exceed the number of wells listed by the PA DEP by factors of 20 or more. To characterize AOL wells' potential as a significant methane source, we made first-of-a-kind measurements of methane fluxes from 8 abandoned wells in McKean County using static flux chambers. These wells are on a 40-acre lot, which includes various land cover types. Four of the eight measured wells are in forested areas, while three are in grassland, and one is in wetland areas. Two of the eight wells, one in a forested area and one in the grassland area, are plugged. Fluxes of methane, ethane, propane, and n-butane were measured using flame ionization gas chromatography. To gain insight into the source of methane (biogenic vs. thermogenic), carbon and hydrogen isotopes of methane were analyzed and the ratio of methane to heavier hydrocarbons were computed. In addition, a LI-7700 open path methane analyzer was used to provide on-line methane concentration measurement in the vicinity of AOL wells and in flux chambers. We found methane fluxes from the measured AOL wells to be significantly higher than fluxes observed in similar natural environments. Methane emissions from the two plugged wells were smaller than those from unplugged wells but

  3. The tidal influence on oil and gas emissions from an abandoned oil well: Nearshore Summerland, California

    Oil and gas emissions were quantified for natural and human sources in nearshore waters off Summerland, California through deployment of custom designed collection tents. Seepage was measured at a repeatedly abandoned well, on the seabed from a caisson located along the historical location of the Treadwell Wharf, where the world's first off-shore oil wells were drilled at the end of the 19th century. Seepage rates at the capped T-10 Well, located in ∼5 m water, showed high correlation to tides. Site emissions were 2.4 and 38.7 L day-1 oil and gas, respectively. Emissions were measured from two areas of seepage at the T-10 Well Site. Oil and gas ratios were inversely correlated between the two seepage areas, demonstrating connectivity. Data were interpreted in terms of an electronic circuit model of seepage with respect to the time lag between local low tide and peak oil emissions

    This study considered the fugitive emissions of methane (CH4) from former oil and gas exploration and production wells drilled to exploit conventional hydrocarbon reservoirs onshore in the UK. This study selected from the 66% of all onshore wells in the UK which appeared to be properly decommissioned (abandoned) that came from 4 different basins and were between 8 and 79years old. The soil gas above each well was analysed and assessed relative to a nearby control site of similar land use and soil type. The results showed that of the 102 wells considered 30% had soil gas CH4 at the soil surface that was significantly greater than their respective control. Conversely, 39% of well sites had significant lower surface soil gas CH4 concentrations than their respective control. We interpret elevated soil gas CH4 concentrations to be the result of well integrity failure, but do not know the source of the gas nor the route to the surface. Where elevated CH4 was detected it appears to have occurred within a decade of it being drilled. The flux of CH4 from wells was 364±677kg CO2eq/well/year with a 27% chance that the well would have a negative flux to the atmosphere independent of well age. This flux is low relative to the activity commonly used on decommissioned well sites (e.g. sheep grazing), however, fluxes from wells that have not been appropriately decommissioned would be expected to be higher.

  5. Fiscal Year 1998 Well Installation, Plugging and Abandonment, and Redevelopment summary report Y-12 Plant, Oak Ridge, Tennessee

    None

    1998-12-01

    This report summarizes the well installation, plugging and abandonment, and redevelopment activities conducted during the federal fiscal year (FY) 1998 at the Y-12 Plant, Oak Ridge, Tennessee. Five new groundwater monitoring wells were installed at the Y-12 Plant under the FY 1998 drilling program. Two of the wells are located in west Bear Creek Valley, one is in the eastern Y-12 Plant area near Lake Reality, and two are located near the Oil Landfarm Waste Management Area, which were installed by Bechtel Jacobs Company LLC (Bechtel Jacobs) as part of a site characterization activity for the Oak Ridge Reservation (ORR) Disposal Cell. Also, two existing wells were upgraded and nine temporary piezometers were installed to characterize hydrogeologic conditions at the Disposal Cell site. In addition, 40 temporary piezometers were installed in the Boneyard/Bumyard area of Bear Creek Valley by Bechtel Jacobs as part of the accelerated remedial actions conducted by the Environmental Restoration Program. Ten monitoring wells at the Y-12 Plant were decommissioned in FY 1998. Two existing monitoring wells were redeveloped during FY 1998 (of these, GW-732 was redeveloped tsvice). All well installation and development (including redevelopment) was conducted following industry-standard methods and approved procedures from the Environmental Surveillance Procedures Quality Control Program (Energy Systems 1988); the Resource Conservation and Recovery Act (RCRA) Groundwater Monitoring Technical Enforcement Guidance Document (EPA 1992); and the Monitoring Well Installation Plan for the Department of Energy Y-12 Plant, Oak Ridge, Tennessee (Energy Systems 1997a). Well installation and development of the non-Y-12 Plant GWPP oversight installation projects were conducted using procedures/guidance defined in the following documents: Work Plan for Support to Upper East Fork Poplar Creek East End Volatile Organic Compound Plumes Well Installation Project, Oak Ridge Y-12 Plant, Oak Ridge

    Worrall, Fred; boothroyd, Ian; Almond, Sam; Davies, Richard

    2015-04-01

    The aim of this study was to consider the potential legacy of increased onshore, unconventional gas production by examining the integrity of decommissioned, onshore, oil and gas wells in the UK. In the absence of a history of unconventional hydrocarbon exploitation in the UK, conventional onshore sites were considered and an examination of pollution incidents records had suggested that only a small fraction of onshore wells could show integrity failures. In this study the fugitive emissions of methane from former oil and gas production wells onshore in the UK were considered as a measure of well integrity. The survey considered 49 decommissioned (abandoned) wells from 4 different basins that were between 8 and 78 years old; all but one of these wells would be considered as having been decommissioned properly, i.e. wells cut, sealed and buried by soil cover to the extent that the well sites were being used for agriculture. For each well site the soil gas methane was analysed multiple times and assessed relative to a nearby control site of similar land-use and soil type. The results will be expressed in terms of the proportion and extent of well integrity failure, or success, over time since decommissioning and relative to local control sites. The probability of failure and the emissions factor for decommissioned wells will be presented.

  7. Implementation of field techniques to stabilize abandoned oil wells - Boyd's creek, Kentucky

    At Boyd's Creek, commercial crude-oil drilling production began in the early 1860s. Countless unrecorded exploration wells were drilled and many have been found to be improperly abandoned. The Corniferous limestone is the first oil producing interval and is situated at an average subsurface depth of 135 feet. The potential for impacting natural resources is high because of the shallow depth(s) of the Corniferous limestone and the presence of overlying artesian sulfur-water zones which routinely mix with brine and oil in uncased boreholes. The occurrence of limestone related (karstic) features, such as fractures and dissolution cavities, and the close proximity of the Boyd's Creek oil field to nearby surface streams are also of concern. Initially, two abandoned wells were identified as flowing into nearby streams. Pursuant to federal removal authority provided by Subsection (c) of Section 311 of the Federal Water Pollution Control Act in accordance with Subtitle B of the Oil Pollution Act of 1990 and the National Contingency Plan, the Environmental Protection Agency has initiated cleanup operations within properties nearest to Boyd's Creek. Most wells are difficult to identify because they lack any casing strings and/or they have been buried with soil to hide uncontrolled flows at the surface. Field operations have included the utilization of multiple geophysical techniques to identify anomaly areas thought to represent buried unplugged wells. These include the excavation of surface soils down to the underlying limestone bedrock to search for cable tool and rotary boreholes, the drilling out of old wells using conventional industry technology and standards to plug them permanently with cement, the construction of temporary underflow dams downgradient from identified oil spills to minimize impacts on Boyd's Creek and its adjoining tributaries, and the burning of spilled product in temporary holding pits to minimize associated cleanup cost

  8. Monitoring well plugging and abandonment plan, Y-12 Plant, Oak Ridge, Tennessee (revised)

    Plugging and abandonment (P ampersand A) of defunct groundwater monitoring wells is a primary element of the Oak Ridge Y-12 Plant Groundwater Protection Program (GWPP) (AJA Technical Services, Inc. 1996). This document is the revised groundwater monitoring well P ampersand A plan for the U.S. Department of Energy (DOE) Y-12 Plant located in Oak Ridge, Tennessee. This plan describes the systematic approach employed by Y-12 Plant GWPP to identify wells that require P ampersand A, the technical methods employed to perform P ampersand A activities, and administrative requirements. Original documentation for Y-12 Plant GWPP groundwater monitoring well P ampersand A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P ampersand A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P ampersand A schedule be maintained. Wells are added to this list by issuance of both a P ampersand A request and a P ampersand A addendum to the schedule. The current Updated Subsurface Data Base includes a single mechanism to track the status of monitoring wells. In addition, rapid growth of the groundwater monitoring network and new regulatory requirements have resulted in constant changes to the status of wells. As a result, a streamlined mechanism to identify and track monitoring wells scheduled for P ampersand A has been developed and the plan revised to formalize the new business practices

    A major question in philosophy of science involves the unreasonable effectiveness of mathematics in physics. Why should mathematics, created or discovered, with nothing empirical in mind be so perfectly suited to describe the laws of the physical universe? We review the well-known fact that the symmetries of the laws of physics are their defining properties. We show that there are similar symmetries of mathematical facts and that these symmetries are the defining properties of mathematics. By...

  12. Isotopic fingerprinting of groundwaters in southwestern Ontario: Applications to abandoned well remediation

    Highlights: • We created a tool to predict sources of groundwaters leaking from abandoned wells. • Each of the main aquifers were characterized, for a total suite of over 130 samples. • 8 isotopes (δ18O, δ2H, δ34SSO4, δ18OSO4, δ13C, 87Sr/86Sr, δ37Cl and δ81Br) were analyzed. • Our tool well-predicted fluid origins in different real and hypothetical scenarios. • Leaking fluids from wells sampled so far were from a shallow Devonian aquifer. - Abstract: Southwestern Ontario has a legacy of unplugged oil and gas wells drilled in the late 1800s and early 1900s before the advent of government regulatory controls. A number of these wells exhibit artesian flow of salty and/or sulphurous water at the surface, creating a liability to landowners and a possible threat to potable groundwater aquifers and the surface environment. Cost-effective plugging of these wells is hindered by incomplete drilling records regarding well depths, well construction, and geologic information on the sources of the leaking fluids. This study seeks to fill this knowledge gap by characterizing distinct geochemical ‘fingerprints’ for each of the major bedrock water-producing zones that may be the possible sources of the leaking fluids. To this end, over 130 groundwater samples were collected and analyzed for a broad suite of isotopic parameters (δ18O, δ2H, δ34SSO4, δ18OSO4, δ13CDIC, 87Sr/86Sr, δ37Cl and δ81Br), and this dataset was combined with available data from previous studies in the area. A Bayesian mixing model, SIAR, was applied to these data to develop a statistical tool for identifying the probable source(s) of leaking fluids. Several hypothetical samples and one real-world example are presented here to demonstrate the model’s performance

    A major question in philosophy of science involves the unreasonable effectiveness of mathematics in physics. Why should mathematics, created or discovered, with nothing empirical in mind be so perfectly suited to describe the laws of the physical universe? We review the well-known fact that the symmetries of the laws of physics are their defining properties. We show that there are similar symmetries of mathematical facts and that these symmetries are the defining properties of mathematics. By examining the symmetries of physics and mathematics, we show that the effectiveness is actually quite reasonable. In essence, we show that the regularities of physics are a subset of the regularities of mathematics.

  14. Regulatory acceptance of the proposed well abandonment program for the present landfill, Operable Unit 7, Rocky Flats Environmental Technology Site, Golden, Colorado

    The regulatory agencies approved a well abandonment program for the Present Landfill, Operable Unit (OU) 7 at the Rocky Flats Environmental Technology Site, only three months after preparation. The proposed well abandonment program consists of abandoning 26 of the 54 existing monitoring wells in OU 7 that are currently sampled quarterly as Resource Conservation and Recovery Act (RCRA) compliance wells or sitewide groundwater protection wells. Well abandonment was proposed on the basis that the purpose of each well has been fulfilled, the wells fall under the footprint of the landfill cap, the presence of the wells would compromise the integrity of the cap because holes would have to be cut in the synthetic liner, and unequal compaction of the fill material around the wells would potentially cause differential settlement of the cap. The proposal provided the technical justification to abandon the wells in place. The timely approval of the proposal by the regulatory agencies will allow the abandonment of the wells during fiscal year 1995 under the sitewide Well Abandonment and Replacement Program (WARP). Cost savings resulting from a decrease in the number of wells to be sampled under the groundwater monitoring program are estimated at $416,000 per year. This paper presents a summary of the well abandonment program, discusses the timely approvals required for implementation, and present the potential cost savings that can be achieved through implementation of the program

    Unplugged abandoned oil and gas wells in the Appalachian region can serve as conduits for the movement of waters impacted by fossil fuel extraction. Strontium isotope and geochemical analysis indicate that artesian discharges of water with high total dissolved solids (TDS) from a series of gas wells in western Pennsylvania result from the infiltration of acidic, low Fe (Fe < 10 mg/L) coal mine drainage (AMD) into shallow, siderite (iron carbonate)-cemented sandstone aquifers. The acidity from the AMD promotes dissolution of the carbonate, and metal- and sulfate-contaminated waters rise to the surface through compromised abandoned gas well casings. Strontium isotope mixing models suggest that neither upward migration of oil and gas brines from Devonian reservoirs associated with the wells nor dissolution of abundant nodular siderite present in the mine spoil through which recharge water percolates contribute significantly to the artesian gas well discharges. Natural Sr isotope composition can be a sensitive tool in the characterization of complex groundwater interactions and can be used to distinguish between inputs from deep and shallow contamination sources, as well as between groundwater and mineralogically similar but stratigraphically distinct rock units. This is of particular relevance to regions such as the Appalachian Basin, where a legacy of coal, oil and gas exploration is coupled with ongoing and future natural gas drilling into deep reservoirs.

  17. Hydro-mechanical simulations of well abandonment at the Ketzin pilot site for CO2 storage verify wellbore system integrity

    Unger, Victoria; Kempka, Thomas

    2015-04-01

    In geological underground utilisation, operating and abandoned wells have been identified as a main potential leakage pathways for reservoir fluids. In the scope of the well abandonment procedure currently carried out at the Ketzin pilot site for CO2 storage in Germany, a hydro-mechanical model was built to carry out a coupled analysis of the integrity in the entire wellbore system. The main aim of the present study was to assess the impacts of stress changes associated with CO2 injection as well as the cement backfill undertaken in the scope of well abandonment. A numerical model comprising cement sheaths, steel casings, tubing, multiple packers and wellbore annuli was implemented to enable a detailed representation of the entire wellbore system. The numerical model grid has a horizontal discretisation of 5 m x 5 m to focus on near wellbore effects, whereby element sizes increase with increasing distance from the wellbore. Vertical grid discretisation uses a tartan grid type over the entire model thickness of 1,500 m to ensure a sufficient discretisation of all wellbore system elements as well as of the reservoir unit. The total number of elements amounts to 210,672. Mechanical model parameters were taken from geological, drilling, logging and laboratory test data based on Ketzin pilot site-specific information as well as related literature (Kempka et al., 2014). The coupled calculations were performed using an elasto-plastic constitutive law, whereby an initial simulation run ensured a static mechanical equilibrium to represent the initial state before the start of CO2 injection. Thereto, gravitational load of the overburden rocks and pore pressure distribution following available well logs were integrated for initial model parameterisation including a normal faulting stress regime defined by a horizontal to vertical total stress ratio of 0.85. A correction accounting for the temperature and pressure dependent CO2 density was carried out in advance of each

  19. The public health effects of abandoned coal mine workings on residents in South Wellington, Nanaimo

    Biagioni, K. [Victoria Univ., BC (Canada)

    2005-07-01

    Abandoned coal mine groundwater frequently contains depressed pH levels and elevated levels of hydrogen sulphide, iron, aluminium and nitrates. Abandoned coal mine groundwater is also usually high in copper, zinc, mercury, and lead. Groundwater from abandoned mines can seriously affect public health through the discharge of non-point source pollution. This paper presents information on a research project regarding the possible impacts of abandoned coal mines and its effects on groundwater as it relates to the health of residents in South Wellington, Nanaimo, British Columbia. The purpose of the project is to determine which illnesses are more common in South Wellington, Nanaimo and in the control area. The paper provides a discussion of the Nanaimo coal field and three major seams; the Wellington, Newcastle and Douglas which are most likely to have a significant impact on groundwater in South Wellington. 27 refs.

  1. Well plugging and abandonment plan for Waste Area Grouping 6 at Oak Ridge National Laboratory, Oak Ridge, Tennessee

    Site environmental characterization and remediation require data obtained from the installation and sampling of wells. When these wells are no longer needed or not producing reliable information, or are damaged and can act as conduits for contaminant migration, they should be identified and properly decommissioned. This is most important for wells of sufficient depth to create the potential for exchange of fluids between different hydrologic units. This plan presents the strategy and detailed approach for well plugging and abandonment (P ampersand A) at Waste Area Grouping 6 (WAG 6). An inventory of 768 wells, the total number known to have been installed in WAG 6 based on a combined review of data and direct field inventory, is provided in Appendix A. All wells that are no required for closure or postclosure surveillance of WAG 6 will be decommissioned. A listing of 69 existing WAG 6 wells that will be maintained for postclosure surveillance is provided in Appendix B, and their locations are shown in Fig. 1. Appendix C contains a list of all WAG 6 wells that will be decommissioned, although some may no longer exist. Their locations are shown in Fig. 2. It is likely that some new wells will be drilled as part of postclosure monitoring of Solid Waste Area 6 (SWSA), but they are beyond the scope of this report. It is intended that this plan provide a basis for developing contracts for cost and schedule determinations for the P ampersand A process

  2. Plugging and abandonment plan for wells and coreholes at Oak Ridge National Laboratory, Oak Ridge, Tennessee

    Site environmental characterization and remediation require data obtained from the installation and sampling of wells and coreholes. When these wells and coreholes are no longer needed, are not producing reliable information, or are damaged and can act as conduits for contaminant migration, they should be identified and properly decommissioned. This is most important for wells of sufficient depth to create the potential for exchange of fluids between different hydrologic units. This plan presents the strategy and detailed approach for the well and corehole P ampersand A plan for most of the areas for which ORNL has responsibility. Although wells in Waste Area Grouping (WAG) 5 and WAG 10 are not specifically addressed in this plan, these wells will be incorporated into the decommissioning program in FY 1993

  3. Underground Pumped Storage Hydroelectricity using Abandoned Works (open pits and deep mines)

    Pujades, E.; Willems, T.; Bodeux, S.; Orban, P.; Dassargues, A.

    2015-12-01

    Pumped Storage Hydroelectricity (PSH) is a good alternative to increase the efficiency of power plants, which cannot regulate the amount of electricity generated according to the demand (wind, solar or even nuclear power plants). PSH plants, which consist in two reservoirs located at different heights (upper and lower), can store energy during low demand periods (pumping water from the lower to the upper reservoir) and generate electricity during the high demand peaks (falling water from the upper to the lower reservoir). Given that the two reservoirs must be located at different heights, PSH plants cannot be constructed in flat regions. Nevertheless, in these regions, an alternative could be to use abandoned underground works (open pits or deep mines) as lower reservoirs to construct Underground Pumped Storage Hydroelectricity (UPSH) plants. To select the best place to construct a plant, two considerations must be taken into account regarding the interaction between UPSH plants and groundwater: 1) the alteration of the natural conditions of aquifers and 2), the efficiency of the plant since the electricity generated depends on the hydraulic head inside the underground reservoir. Obviously, a detailed numerical model must be necessary before to select a location. However, a screening methodology to reject the most disadvantageous sites in a short period of time would be useful. Groundwater flow impacts caused by UPSH plants are analyzed numerically and the main variables involved in the groundwater evolution are identified. The most noticeable effect consists in an oscillation of the groundwater. The hydraulic head around which groundwater oscillates, the magnitude of the oscillations and the time to achieve a "dynamic steady state" depend on the boundaries, the parameters of the aquifer and the characteristics of the underground reservoir. A screening methodology is proposed to assess the main impacts caused in aquifers by UPSH plants. Finally, the efficiency

  4. New Strategies for Finding Abandoned Wells at Proposed Geologic Storage Sites for CO2

    Hammack, R.W.; Veloski, G.A.

    2007-09-01

    Prior to the injection of CO2 into geological formations, either for enhanced oil recovery or for CO2 sequestration, it is necessary to locate wells that perforate the target formation and are within the radius of influence for planned injection wells. Locating and plugging wells is necessary because improperly plugged well bores provide the most rapid route for CO2 escape to the surface. This paper describes the implementation and evaluation of helicopter and ground-based well detection strategies at a 100+ year old oilfield in Wyoming where a CO2 flood is planned. This project was jointly funded by the U.S. Department of Energy’s National Energy Technology Laboratory and Fugro Airborne Surveys.

    The authors describe underground measurement of the electrical resistance of rocks, and the precautions which must be taken to get valid results. A study was carried out in a Polish coal mine which was not gassy and where there were no rockbursts. In this case, the effect of the abandoned working was small. An important factor is the spacing of the measuring electrodes. (In Polish)

  6. A contribution to risk analysis for leakage through abandoned wells in geological CO2 storage

    2010-01-01

    The selection and the subsequent design of a subsurface CO2 storage system are subject to considerable uncertainty. It is therefore important to assess the potential risks for health, safety and environment. This study contributes to the development of methods for quantitative risk assessment of CO...... reservoir database, holding data from over 1200 reservoirs An analytical risk equation is given, allowing the calculation of average risk due to multiple leaky wells with varying distance in the surrounding of the injection well. The reservoir parameters most affecting risk are identified. Using these...... results, the placement of an injection well can be optimized with respect to risk and uncertainty of leakage The risk and uncertainty assessment can be used to determine whether a site, compared to others, should be considered for further investigations or rejected for CO2 storage...

    Full Text Available This paper is the result of a research related to the school culture studies. The school culture is an important theoretical key for the internal comprehension of the day-to-day of the school, by focusing on the interaction of the school´s actors. Our goal was to comprehend the functionalism of the abandonment of teaching in Physical Education (PE for the school culture. It was an ethnomethodological research and carried out in a school situated in Curitiba – PR, using field diary and biographical interview as instruments for data collection. We observed two classes of PE, one of the 4th and another of the 5th school year. We concluded that the abandonment of teaching in PE is functional to the school culture, being supported by other actors of the school day living.

  8. Why most agricultural terraces in steep slopes in semiarid SE Spain remain well preserved since their abandonment 50 years go?

    Cantón, F.

    2010-12-01

    Full Text Available A large part of the agricultural terraces in mountain environments are abandoned, like those from the Filabres range in Almería, SE Spain. While many of such terraces show signs of soil erosion (wall disruptions, surface crusts, pipes and gullies, others in steep slopes remain well preserved after 50 years since their abandonment and still seem to play an active role against soil erosion. In order to know both magnitude of soil erosion and controlling factors in different types of abandoned terraces, a rainfall simulation campaign with a portable sprinkler was carried out in 45 representative microsites. Runoff, derived-infiltration and sediment production were measured and their relationships to basic soil parameters (particle size distribution, pH, EC, organic matter content, aggregate stability, geomorphic position, and ground cover, were examined. Under the average applied rainfall intensity (48 mm/h, which represents a precipitation with a return period of 5 years in the area, narrow bench terraces from steep hillslopes, have larger infiltration values and deliver less sediments than large bank terraces in alluvial plains. The presence of stony pavement sieving crusts on narrow-bench terraces and also on un-terraced alluvial fans, play an essential armouring effect against soil erosion while favouring water infiltration. Considerations are made about the evolution of the different types of traditional terraces in the area under both past agricultural and present abandoned status, and also about possible uses under a sustainable land management policy.

    Una gran parte de las terrazas agrícolas en zonas de montaña están abandonadas, como las de la Sierra de los Filabres en Almería, SE de España. Si bien muchas de dichas terrazas muestran señales de erosión hídrica (destrucción de muros, encostramiento superficial, piping y cárcavas, otras en laderas con pendientes acusadas siguen bien conservadas tras 50 años de abandono y

  9. Why Internally Coupled Ears (ICE) Work Well

    van Hemmen, J. Leo

    2014-03-01

    Many vertebrates, such as frogs and lizards, have an air-filled cavity between left and right eardrum, i.e., internally coupled ears (ICE). Depending on source direction, internal time (iTD) and level (iLD) difference as experienced by the animal's auditory system may greatly exceed [C. Vossen et al., JASA 128 (2010) 909-918] the external, or interaural, time and level difference (ITD and ILD). Sensory processing only encodes iTD and iLD. We present an extension of ICE theory so as to elucidate the underlying physics. First, the membrane properties of the eardrum explain why for low frequencies iTD dominates whereas iLD does so for higher frequencies. Second, the plateau of iTD = γ ITD for constant 1 gecko ν∘ ~ 1 . 5 kHz. Third, we use a sectorial instead of circular membrane to quantify the effect of the extracolumella embedded in the tympanum and connecting with the cochlea. The main parameters can be adjusted so that the model is species independent. Work done in collaboration with A.P. Vedurmudi and J. Goulet; partially supported by BCCN-Munich.

  10. Geothermal well site restoration and plug and abandonment of wells, DOE Gladys McCall test site, Cameron Parish, Louisiana and DOE Willis Hulin test site, Vermillion Parish, Louisiana

    Rinehart, Ben N.

    1994-08-01

    A report is presented on the final phase of an energy research program conducted by the U.S. Department of Energy (DOE) involving two geothermal well sites in the State of Louisiana--the Gladys McCall site and the Willis Hulin site. The research program was intended to improve geothermal technology and to determine the efficacy of producing electricity commercially from geopressured resource sites. The final phase of the program consisted of plug and abandonment (P&A) of the wells and restoration of the well sites. Restoration involved (a) initial soil and water sampling and analysis; (b) removal and disposal of well pads, concrete, utility poles, and trash; (c) plugging of monitor and freshwater wells; and (d) site leveling and general cleanup. Restoration of the McCall site required removal of naturally occurring radioactive material (NORM), which was costly and time-consuming. Exhibits are included that provide copies of work permits and authorizations, P&A reports, and cost and salvage reports. Site locations, grid maps, and photographs are provided.

  11. APPLICATION OF HIGH-RESOLUTION MAGNETIC METHOD AND GRADIENT METHOD TO LOCATE ABANDONED BRINE-WELLS IN HUTCHINSON, KANSAS, U.S.A.

    CHEN Chao; XIA Jianghai; XIA Sihao; David Laflen; Stephen L. Williams

    2004-01-01

    After successfully locating one abandoned brine well by an electromagnetic method during testing in 2001 and five abandoned brine wells by a high-resolution magnetic method during 2002, a high-resolution magnetic method was again proposed to search for wells in 2003 when a second sensor was employed to acquire data for calculating the pseudo-vertical gradient of magnetic fields. Total area surveyed in 2003 was 1,024,000 ft2, which was divided into grids with an average size of 10,000 ft2 and distributed across eight different sites. Magnetic anomalies and their vertical gradients from known brine wells were first recorded as signatures to identify anomalies caused by possible buried brine wells. Of fifty-one verified anomalies, thirtyone anomalies were due to wells buried at depths from 0 to 8.5 ft: twenty-one 6- to 9-inch abandoned brine wells, seven 1.5- to 3-inch probable water wells, one 16-inch dewatering well for a construction site at a depth of 3 ft, and two 4-inch wells on the ground surface. Approximate monopole shaped anomalies were observed from all these wells after data corrections. However, the range of amplitudes of magnetic anomalies from 7,000 to 28,000 nT from these abandoned brine wells was measured. This range of anomalies is mainly due to the thickness and depth of buried wells. Anomaly amplitudes from 1.5- to 3-inch wells are 4,000 to 8,000 nT and linearly correlate with the buried depth. One 3-inch well that caused an anomaly of 13,000 nT could be the inner pipe of a brine well. Gradient anomalies are roughly in a range of 100 to 200 nT/inch for 1.5-to 3-inch wells and 200 to 300 nT/inch for brine wells.As indicated by the potential-field theory, gradient data possess higher horizontal resolution than the magnetic field itself. Gradient data provide valuable assistance in determining horizontal locations of anomaly sources for excavation. In practice, however, improvement in the horizontal resolution is limited by surveyline spacing. If only

    Stéphane Moulin

    2012-06-01

    Full Text Available Dans de nombreux pays, les élèves et les étudiants ont augmenté le temps consacré au travail rémunéré durant leurs études. Ils ne travaillent plus uniquement l’été, au moment des vacances, mais aussi pendant l’année scolaire. Les recher­ches portant sur l’effet du travail salarié sur les parcours scolaires tendent à montrer qu’il existe une relation convexe entre l’intensité du travail salarié et les départs sans diplôme du système scolaire : les taux d’abandon semblent plus élevés pour les étudiants qui ne travaillent pas et pour ceux qui travaillent plus de 25 heures. Cependant, le caractère transversal des données utilisées fait qu’elles ne permettent pas de saisir l’effet causal de la variation du temps de travail sur la poursuite des études. Dans cet article, nous utilisons une méthodologie quantitative longitudinale pour examiner les effets de l’intensité du travail rémunéré sur la persévérance dans le premier programme universitaire suivi au Canada. Les résultats montrent qu’il y a bien une relation causale entre le fait de travailler plus de 25 heures et l’abandon, mais qu’elle est seulement observée pour les hommes, et que cet effet n’est significatif qu’au début du program­me. Par ailleurs, l’association avec le fait de ne pas travailler semble s’inter­préter davantage comme un effet de sélection.In many countries, pupils and students have increased the time devoted to remunerated work during their studies. They no longer work just in summer, during vacations, but also during the school year. Research relating to the effect of salaried work on the school courses tends to show that there exists a convex relationship between the intensity of the salaried work and the departures without diplomas from the school system: the rates of abandonment seem higher for students who do not work and for those who do not work or work over 25 hours weekly. However, the

  15. Mineralogical characterization of tailing dams: incidence of abandoned mining works on soil pollution (Linares, Jaén)

    de la Torre, M. J.; Hidalgo, C.; Rey, J.; Martínez, J.

    2012-04-01

    The metallogenic district of Linares-La Carolina (Jaén, Spain) consists of dyke mineralizations mainly of galena, accompanied by blende, chalcopyrite and barite. Associated to these abandoned mines, relatively extensive areas occupied by spoil heaps and tailing impoundments exist and constitute potential sources of soil pollution by metals and semimetals. In order to analyze the pollution potential of these mining wastes, we have carried out a mineralogical and geochemical study of seven tailing dams and surrounding soils in the area. The mineralogy of the samples was studied by x-ray diffraction (XRD) and scanning electron microscope (SEM). In addition, the total metal content of samples was determined by inductively coupled plasma mass spectrometry (ICP-MS) analysis. Samples were taken from the first 30 cm of the waste piles and soil deposits and white efflorescences were also obtained from the surface of the tailings. In all analyzed heaps, high to very high total contents in Pb (1220-22890 mg/kg), Zn (150-51280 mg/kg), Mn (2658-4160 mg/kg), Ba (1026-19610 mg/kg) and Fe (19400-138000 mg/kg) were observed. The concentrations for these same elements in the studied soils range from 527-9900 mg/kg for Pb, 27-1700 mg/kg for Zn, 506-2464 mg/kg for Mn, 2832-4306 for Ba and 8642-29753 mg/kg for Fe, and these figures indicate a contamination of the soils, according to the guidelines established by the Spanish law. The XRD and SEM results indicate that the tailings are primarily constituted by gangue of the exploited mineralization: quartz, calcite, ankerite, feldspars and phyllosilicates. They are inherited, primary mineral phases. Galena, also primary, appears in low proportion, as well as lepidocrocite, melanterite and cerussite, being these three last secondary minerals and indicating a certain remobilization of metal cations, especially lead and iron. On the other hand, quartz and phyllosilicates predominate in the soils, in which, in addition, is identified a

    This work plan provides the information necessary for drilling, sampling, and hydrologic testing of wells to be completed in support of a demonstration of the in-well vapor stripping system. The in-well vapor stripping system is a remediation technology designed to preferentially extract volatile organic compounds (VOCs) from contaminated groundwater by converting them to a vapor phase. Air-lift pumping is used to lift and aerate groundwater within the well. The volatiles escaping the aerated water are drawn off by a slight vacuum and treated at the surface while the water is allowed to infiltrate the vadose zone back to the watertable

  20. Long-term changes in the quality of polluted minewater discharges from abandoned underground coal workings in Scotland

    Wood, S.C.; Younger, P.L.; Robins, N.S.

    1999-01-01

    Long-term trends of changes in the quality of water discharging from abandoned coal mines have been studied for 32 long-established discharges in the Midland Valley of Scotland. Six discharges have been studied in greater detail, providing insights into discharge quality evolution over more than a century. It has been found that minewater pollution is most severe in the first few decades after a discharge begins (the ‘first flush’), and that even the largest systems settle down to a lower lev...

  1. Reconceptualising Well-being: Social Work, Economics and Choice

    Graeme Simpson

    2014-10-01

    Full Text Available In this paper we examine the intersection of well-being, agency and the current political and economic structures which impact on social work with adults and in doing so contribute to ‘interpreting and mapping out the force fields of meaning production' (Fornäs, Fredriksson & Johannisson 2011: 7. In it we draw upon Sointu's (2005 work which identified the shift from conceptualising well-being in terms of ‘the body politic' to conceptualising it in terms of ‘the body personal' and identified parallels with understanding well-being in English social work. There has been a shift in the nature of social work in the United Kingdom in how the question of agency has been addressed. For many years this was through the traditional notion of autonomy and self-determination (Biestek 1961 and later collective approaches to welfare and services (Bailey and Brake 1975. The development of paradigms of mainly personal empowerment in the 1980s and 1990s (Braye & Preston-Shoot 1995 saw social work become less associated with collective engagement in welfare and more concerned with the enhancement of individual well-being (Jordan 2007. Whilst the rhetoric of well-being, in contemporary English social work, continues to include autonomy and self-determination, this is focused primarily upon the narrower concepts of independence and choice (Simpson 2012. The UK Department of Health's A Vision for Adult Social Care: Capable Communities and Active Citizens (DoH 2010 is the template for national social care policy to which all Local Authorities in England had to respond with an implementation plan. This paper draws on a documentary analysis of two such plans drafted in 2012 in the wake of an ‘austerity budget' and consequent public ex-penditure reductions. The analysis considers the effect of economic imperatives on the conceptualisation of individual choices and needs in the context of Local Au-thorities' responsibilities to people collectively.

  2. Abandoned vehicles

    Relations with the Host States Service

    2004-01-01

    The services in charge of managing the CERN site have recently noted an increase in the number of abandoned vehicles. This poses a risk from the point of view of safety and security and, on the eve of several important events in honour of CERN's fiftieth anniversary, is detrimental to the Organization's image. Owners of vehicles that have been left immobile for some time on the CERN site, including on the external car park by the flags, are therefore invited to contact the Reception and Access Control Service (service-parking-longterm@cern.ch) before 1st October 2004 and, where appropriate, move their vehicle to a designated long-term parking area. After this date, any vehicle whose owner has failed to respond to this request and which is without a number plate, has been stationary for several weeks or is out of service, may be impounded at the owner's risk and expense.

  3. Work engagement, work commitment and their association with well-being in health care.

    Kanste, Outi

    2011-12-01

    The aim was to examine whether work engagement and work commitment can be empirically discriminated and how they are associated with well-being. The terminology used in literature and in practice is confused by the interchangeable use of these terms. Only few studies, like Hallberg and Schaufeli's study, have examined the relationships between work engagement and work commitment systematically by using empirical data. In this study, the data were gathered via self-reported questionnaire from the healthcare staff working in 14 health centres and four hospitals in Finland. The data consisted of 435 responses. The material was analysed by using structural equation modelling (SEM) and correlations. The items of work engagement and work commitment dimensions (identification with organization, willingness to exert in organization's favour, occupational commitment and job involvement) loaded on their own latent variables in SEM analysis, so the data supported this five-factor model. Work engagement and work commitment dimensions were positively related, sharing between 2 and 33% of their variances. These constructs also displayed different correlations with some indicators of well-being measured as personal accomplishment, psychological well-being, mental resources, internal work motivation and willingness to stay on at work. Work engagement had moderate positive correlation to personal accomplishment (r = 0.68, p engagement can be empirically discriminated from work commitment. They are distinct, yet related constructs that complement each other, describing different aspects of positive attitudes towards work. The results can be utilized in interventions aimed at quality of working life in health care as well as in studies investigating discriminant and construct validity. PMID:21564150

    2012-05-01

    Full Text Available Abstract Background Insufficient PA has been shown to cluster with other CVD risk factors including insufficient fruit and vegetable intake, overweight, increased serum cholesterol concentrations and elevated blood pressure. This paper describes the development of Working on Wellness (WOW, a worksite intervention program incorporating motivational interviewing by wellness specialists, targeting employees at risk. In addition, we describe the evaluation the effectiveness of the intervention among employees at increased risk for cardiovascular disease. Methods The intervention mapping (IM protocol was used in the planning and design of WOW. Focus group discussions and interviews with employees and managers identified the importance of addressing risk factors for CVD at the worksite. Based on the employees’ preference for individual counselling, and previous evidence of the effectiveness of this approach in the worksite setting, we decided to use motivational interviewing as part of the intervention strategy. Thus, as a cluster-randomised, controlled control trial, employees at increased risk for CVD (N = 928 will be assigned to a control or an intervention group, based on company random allocation. The sessions will include motivational interviewing techniques, comprised of two face-to-face and four telephonic sessions, with the primary aim to increase habitual levels of PA. Measures will take place at baseline, 6 and 12 months. Secondary outcomes include changes in nutritional habits, serum cholesterol and glucose concentrations, blood pressure and BMI. In addition, healthcare expenditure and absenteeism will be measured for the economic evaluation. Analysis of variance will be performed to determine whether there were significant changes in physical activity habits in the intervention and control groups at 6 and 12 months. Discussion The formative work on which this intervention is based suggests that the strategy of targeting

  6. Why has the Nordic electricity market worked so well

    There are two major threats to the success of electricity market reform in the Nordic countries. The first is that security of supply can not be maintained. The second is that market power prevents the potential benefits of competition to be realized. So far security of supply has been maintained, although exceptional storms have created serious problems in electricity distribution. The major power companies have been accused of exercising market power, but convincing proofs are lacking. At the same time power industry productivity has increased, and retail electricity prices (before tax) have become strongly linked to wholesale electricity prices. The situation may change in the future. Thus it remains to be seen that investments in new capacity are carried out when they are needed, and that mergers and capacity expansion do not significantly increase concentration and market power. But the development of the Nordic electricity market so far to a large extent is quite successful. Does this mean that the 'Nordic model' should be adopted all over the world? The answer is 'no'. In many ways the success of the Nordic model depends on area specific factors such as ample supply of hydropower and significant inter-connector capacities. Yet there are some 'universal' lessons that can be learned from the Nordic experiences. In particular the Nordic experiences suggest that a 'deregulated' market for electricity works well if: There are no price regulations and constraints on the development of financial markets; There is continued political support for a market based electricity supply system also when electricity is scarce and prices are high

  7. Blasting as a method for abandoned mine land reclamation

    Blasting methods have been proposed for reclaiming abandoned underground coal mine sites having unstable conditions. The objective of blasting is twofold: the permanent stabilization of an area by the collapse of underground workings to prevent any future subsidence, and the use of blasting to close existing sinkholes. This paper presents the results of two research projects funded by the Bureau of Mines Abandoned Mine Land Research Program to investigate the feasibility of blasting to assist in the reclamation of shallow abandoned coal mine sites. Blasting tests were conducted at Beulah, North Dakota and at Scobey, Montana, involving different configurations. The first test was a 10-acre site where blasting was used to collapse regular room and pillar panels for which good mine layout information was available. The second test involved a one acre site containing very irregular workings for which there was little available information. Finally, blasting techniques were used to close 13 individual vertical openings. The depths to the coal seams were 60 feet or less at all sites. When blasting for Abandoned Mine Land Reclamation, material must be cast downward into the abandoned developments or laterally into the sinkhole. Designs based on cratering concepts and spherical charges worked well. The blasting techniques successfully collapsed and stabilized the test areas. Cost of reclamation for the two test sites are presented. Data from blast vibration monitoring are presented because control of vibrations is of concern when mitigation efforts are conducted near homes

  8. Occupational health for what were, a well work force

    Spiller, Roger [MSF, Stowmarket (United Kingdom)

    1997-12-31

    This paper contrasts the offshore scene of 30 years ago with today, within the limits of inadequate monitoring, then and now. It identifies stress, bullying, change, long working hours and offshore trips and lifestyle as major factors that now have to be addressed if the health of the ageing work force is not to be compromised. Activity external to formal working hours such as travel to and from home and domestic and social relationships are all modified by the nature of offshore work but rarely acknowledged as the responsibility of the employer or operator. The development of a superior lifelong health tracking system is essential for long-term surveillance and epidemiological studies. The acceptance by operators of their long-term responsibilities for staff and the families of offshore workers needs to be better developed. (author)

  9. Work Stress and Well-being in the Hotel Industry

    O'Neill, John W.; Davis, Kelly

    2013-01-01

    Employee stress is a significant issue in the hospitality industry, and it is costly for employers and employees alike. Although addressing and reducing stress is both a noble goal and is capable of resulting in expense reductions for employers, the nature and quantity of hospitality employee stress is not fully understood. The first aim of this study was to identify common work stressors in a sample of 164 managerial and hourly workers employed at 65 different hotels who were each interviewed for eight consecutive days. The two most common stressors were interpersonal tensions at work and overloads (e.g., technology not functioning). The second aim was to determine whether there were differences in the types and frequency of work stressors by job type (i.e., managers v. non-managers), gender, and marital status. Hotel managers reported significantly more stressors than hourly employees. There were no significant differences by gender or marital status. The third aim was to investigate whether the various stressors were linked to hotel employee health and work outcomes. More employee and coworker stressors were linked to more negative physical health symptoms. Also, interpersonal tensions at work were linked to lower job satisfaction and greater turnover intentions.

    2016-01-01

    Underground pumped storage hydroelectricity (UPSH) plants using open-pit or deep mines can be used in flat regions to store the excess of electricity produced during low-demand energy periods. It is essential to consider the interaction between UPSH plants and the surrounding geological media. There has been little work on the assessment of associated groundwater flow impacts. The impacts on groundwater flow are determined numerically using a simplified numerical model which is assumed to be ...

  20. Determinants of the exclusive breastfeeding abandonment: psychosocial factors

    Mariana Campos Martins Machado

    2014-12-01

    Full Text Available OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90, 47.6% (n = 80, and 69.6% (n = 117, respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process.

  2. Investigation report on the discharge of synthetic based drilling mud during abandonment of the Crimson F-81 exploration well by Marathon Canada Petroleum ULC

    This report presented details of an investigation conducted by the Canada-Nova Scotia Offshore Oil and Gas Board in conjunction with Environment Canada to determine the causes of a release of synthetic based mud (SBM) from an exploration well owned by Marathon Canada Petroleum ULC. It was established that the cause of the spill was a failure in a rubber compound seal ring, a part of the riser lower flex joint which, during drilling operations, is located approximately 17.6 meters above the sea floor. The failure allowed the SBM to be discharged until the hydrostatic pressures were equalized. A review of the fate and effects of the SBM discharge undertaken by Marathon Canada was evaluated. An outline of events leading up to the spill was presented. It was determined that the impact was confined to the sea floor at a depth of over 2 km. The SBM dispersed in shallow streams on the sea floor, tending to flow down slope away from the drillsite. SBM is formulated to have low toxicity in the marine environment and the environmental impact of the spill was expected to be minor with no remediation recommended. The investigation also determined that appropriate drilling practices and inspections were conducted by Marathon Canada, and the failure of the seal in the flex joint could not have been reasonably anticipated and avoided. It was concluded that based on this incident, enhanced procedures, documentation and inspections are recommended to prevent a similar event occurring in the future. 1 tab., 10 figs

  4. The rail abandonment process: A southern perspective

    One factor in evaluating the desirability of rail transport for high-level radioactive wastes or spent fuels is the frequency, or lack thereof, with which railroad and railroad lines have been, and are, abandoned. If DOE makes a decision to use the rail option and a line is subsequently abandoned, the choice results in increased cost, time delays and possibly safety problems: Information is therefore needed prior to the decision-making process to evaluate the desirability of the rail shipping option. One result of the abandonments mentioned herein, as well as other later abandonments, is the creation of a US rail system undergoing an evolutionary process in the 1980s as far-reaching as the changes that occurred when the industry was in its infancy a century and-a-half ago. The purpose of this paper is to examine the factors leading to some of these changes by tracing the historical development of the rail abandonment process, with particular emphasis on the rise of regional railroads, their problems in the modern era and current trends in rail abandonments as well as their effects on the southeastern United States

Using Chi-Square technique, the survey examines three hypotheses and the results confirm all three hypotheses of the survey.

  7. The home as a workplace: work-family interaction and psychological well-being in telework.

    Standen, P; Daniels, K; Lamond, D

    1999-10-01

    Home-based telework is a growing phenomenon with great potential to affect employees' psychological well-being. Although prior studies show both positive and negative effects on work-family interaction, conclusions are limited by the way telework, well-being, and work-family interaction have been modeled. The authors present a conceptual framework that describes telework as a multidimensional phenomenon and separates the effects of the home environment from those of distance from the organization. Propositions concerning work-family interaction are developed from P. Warr's (1987) model of the environmental antecedents of well-being, prior telework studies, and the work-family literature. Spillover between work and nonwork domains of well-being is discussed, and suggestions for future research on this complex issue are presented. PMID:10526841

  8. Individual Differences in Work-Related Well-Being: The Role of Attachment Style

    2014-11-01

    Full Text Available Integrating theories of adult attachment and well-being at the workplace, the present study tested the role of attachment style in predicting work-related well-being in terms of job satisfaction and job involvement, over and above dispositional trait measures (emotional traits and work-related traits. A sample of workers took part in a correlational study that explored the relationships among a adult attachment, b emotional traits, c work-related traits, and d work-related well-being indices. The results showed that both secure and anxious attachment style explained workers’ job involvement, whereas the secure and avoidant attachment styles explained workers’ job satisfaction. The current findings thus confirm and expand the literature's emphasis on studying the variables and processes that underlie people's mental health in the work setting, and have implications for assessing and promoting well-being in the workplace.

  20. Critical viewpoint to early childhood education teachers’ well-being at work

    Outi Ylitapio-Mäntylä

    2012-02-01

    Full Text Available Early childhood education teachers’ happiness at work reflects in children. Finnish day care system has faced plenty of changes and they can also reflect in well-being at day care. The aim of this article to dissect the state of well-being and thriving at work in Finnish day care centers from early childhood education teachers’ point of view and to discuss how well-being could be promoted. The data comprises group interviews (N=9 collected with memory-work method among North-Finnish early childhood education teachers (N=4. The results revealed that several factors were reported as threatening early childhood education teachers’ well-being. These kinds of factors were, among others, increasing amount of administrative tasks as well as concern about their educational task becoming narrower, the sufficiency of one’s own resources, and how the economic measures for efficiency have started to extend to day care as well. Perceived well-being increases when early childhood education teachers have time to encounter an individual child and concentrate on their basic work, rearing and teaching children. Based on the findings, suggestions how to enhance early childhood education teachers’ well-being are discussed. Promotion of well-being necessitates development actions both at the level of society, day care system and early childhood education teachers’ personal level. In this article, we highlight how organizational structures enhance or hinder well-being.

Using data from the Panel Study of Income Dynamics and the Child Development Study, this study examines patterns of wages, work hours, and time spent on welfare in relation to children's well-being (N = 820). Six patterns…

  5. The reliability of WorkWell Systems Functional Capacity Evaluation: a systematic review

    Bieniek, Sebastian; Bethge, Matthias

    2014-01-01

    Background Functional capacity evaluation (FCE) determines a person’s ability to perform work-related tasks and is a major component of the rehabilitation process. The WorkWell Systems (WWS) FCE (formerly known as Isernhagen Work Systems FCE) is currently the most commonly used FCE tool in German rehabilitation centres. Our systematic review investigated the inter-rater, intra-rater and test-retest reliability of the WWS FCE. Methods We performed a systematic literature search of studies on t...

  6. Mindfulness at Work and Its Relationship to Contextual Performance and Well-Being

    Rauch, Tina

    2011-01-01

    The occurrence of mindfulness trainings in profit organisations is on the increase. However, mindfulness as a quality of consciousness has rarely been investigated in work settings or with work-related concepts. Thus, the present thesis examines mindfulness in relation to contextual performance and work-related well-being. Based on literature analyses I propose three hypotheses: Firstly, mindfulness is positively associated with helping and cooperating with others, mediated by empathy. Second...

  8. Direct and indirect links between organizational work-home culture and employee well-being

    T. A. Beauregard

    2011-01-01

    The extent to which an organization's culture exhibits support for its employees' efforts to balance work and personal responsibilities has been shown to influence a number of work- and home-related outcomes. This study tests a model with a mix of mediated and moderated relationships to investigate direct and indirect routes by which work-home culture may affect employee well-being. Sex differences in these relationships are also explored. Data collected from public sector employees in the UK...

    2004-01-01

    With the introduction of positive psychology the aim with organisational psychology shifted to finding the 'happy/productive' worker and focusing more on work wellness. Historically, working in a higher education institution has generally been considered relatively stress-free and highly satisfying. However, recently the world of work has started to change drastically, which also holds true for higher education institutions. Since 1994, the democratic post apartheid government ...

  10. Worker well-being and the importance of work: bridging the gap

    Spencer, DA; Budd, JW

    2015-01-01

    The importance of worker well-being is widely-embraced both in theory and policy, but there are numerous perspectives on what it is, how to measure it, whether it needs improving and if so, how to improve it. We argue that a more complete approach to worker well-being needs to consider workers as full citizens who derive and experience both public and private benefits and costs from working. A broad framework on the meanings of work is used to expand the boundaries of worker well-being to ref...

  11. Working with the Well Sibling: The Perspective of the Marriage and Family Therapist

    Bonenberger, Christina Elizabeth

    2014-01-01

    Recent research on working with families in which one child is suffering from a developmental disability has indicated a need for more focused clinical attention on the well sibling or neurotypical sibling experience. Research has also suggested that a systemic approach to the therapeutic process would be the most beneficial to all members of the family system, including the well sibling. Although the literature supports the use of systemic interventions in supporting the well sibling, there ...

  13. Work characteristics and employee well-being within a context of strategic downsizing.

    Parker, S K; Chmiel, N; Wall, T D

    1997-10-01

    Findings from this 4-year longitudinal study of strategic downsizing suggest that introducing deliberate work organization and change management strategies can combat the negative effects of reduced head count. Results showed that there was no overall decrease in well-being from before to after downsizing for the 139 employees remaining in an organization, despite an increase in work demands. The potential detrimental effect of demands appears to have been offset by improvement in work characteristics arising from initiatives introduced as part of the downsizing strategy. This interpretation is consistent with analyses at the individual level, which showed that high demands were associated with poorer well-being but that increases in control, clarity, and participation were associated with improved well-being.

  14. Work, malaise, and well-being in Spanish and Latin-American doctors

    Ochoa, Paola; Blanch, Josep M

    2016-01-01

    ABSTRACT OBJECTIVE To analyze the relations between the meanings of working and the levels of doctors work well-being in the context of their working conditions. METHOD The research combined the qualitative methodology of textual analysis and the quantitative one of correspondence factor analysis. A convenience, intentional, and stratified sample composed of 305 Spanish and Latin American doctors completed an extensive questionnaire on the topics of the research. RESULTS The general meaning of working for the group located in the quartile of malaise included perceptions of discomfort, frustration, and exhaustion. However, those showing higher levels of well-being, located on the opposite quartile, associated their working experience with good conditions and the development of their professional and personal competences. CONCLUSIONS The study provides empirical evidence of the relationship between contextual factors and the meanings of working for participants with higher levels of malaise, and of the importance granted both to intrinsic and extrinsic factors by those who scored highest on well-being.

  16. The interplay of occupational motivation and well-being during the transition from university to work.

    Haase, Claudia M; Heckhausen, Jutta; Silbereisen, Rainer K

    2012-11-01

    A successful entry into work is one of the key developmental tasks in young adulthood. The present 4-wave longitudinal study examined the interplay between occupational motivation (i.e., goal engagement and goal disengagement) and well-being (i.e., satisfaction with life, satisfaction with work, satisfaction with partnership, positive affect, depressive symptoms, autonomy, purpose in life, positive relations with others) during the transition from university to work. The sample consisted of 498 university graduates from 4 majors with favorable or unfavorable employment opportunities. Data were analyzed using latent growth curve modeling. The results showed that increases in goal engagement were associated with increases in numerous aspects of well-being. Increases in goal disengagement were associated with decreases in numerous aspects of well-being. However, this dynamic was not without exception. Goal engagement at graduation was associated with a decrease in autonomy and, for individuals with unfavorable employment opportunities, an increase in depressive symptoms. Goal disengagement at graduation was associated with an increase in satisfaction with work. These findings elucidate why some individuals may opt for overall maladaptive motivational strategies during the transition into the workforce: They provide selective well-being benefits. In sum, how young adults deal with their occupational goals is closely linked to changes in their well-being. PMID:22182299

  17. A new approach to measuring work-related well-being.

    Orsila, Reetta; Luukkaala, Tiina; Manka, Marja-Liisa; Nygard, Clas-Hakan

    2011-01-01

    The main aim of this study was to develop a short questionnaire to assess work-related well-being from the organizational behaviour perspective. The short well-being questionnaire enables measuring longitudinal work-related well-being. Work-related well-being was assessed with a 147-item questionnaire covering both organizational and intrinsic factors of work-related well-being. The questionnaire consisted of 27 categories. The respondents were 114 women (65%) and 62 men (35%), mean age 39.2 years, in various occupations. From the extensive questionnaire a shorter questionnaire with 33 items was developed by principal component analysis. The Kaiser-Meyer-Olkin measure to test the sampling adequacy of 27 factor solutions varied from .62 to .91 and Cronbach?s α was .74-.94. Most κ values of the shorter questionnaire were .50-.94 (p < .001). The reliability of the short version was comparable to that of the original questionnaire. The short one could also be suitable for Internet and mobile questionnaire applications. PMID:22152501

    2011-03-01

    Full Text Available Orientation: Hospital pharmacists in South Africa are experiencing increased stress because of the high demand for their services, a lack of resources in hospital pharmacies, and the shortage of pharmacists in South Africa.Research purpose: The objective of this study was to investigate whether job stress and coping strategies could predict the work-related well-being (burnout and work engagement of hospital pharmacists in South Africa.Motivation for the study: Information about the work-related well-being and coping strategies of hospital pharmacists could be used to plan individual and organisational interventions which can be used to retain them and to manage their well-being and performance.Research design, approach and method: A survey design was used. A stratified random sample (N = 187 of pharmacists in South African hospitals was studied. The Maslach Burnout Inventory – Human Services Survey, Utrecht Work Engagement Scale, Pharmacist Stress Inventory and the COPE questionnaire were administered.Main findings: The results showed that job related stress and three coping strategies (approach coping, avoidant coping, and turning to religion predicted burnout and work engagement of South African hospital pharmacists.Practical implications: Job stressors that are in the main responsible for the unfavourable work environment and that lead to the development of burnout amongst hospital pharmacists should be addressed. It is also important to enhance the coping capabilities of the hospital pharmacists.Contribution/value-add: The findings of this study provide insight into the factors impacting on the work-related well-being of hospital pharmacists in South Africa.

  20. LMX, Breach Perceptions, Work-Family Conflict, and Well-Being: A Mediational Model.

    Hill, Rachel T; Morganson, Valerie J; Matthews, Russell A; Atkinson, Theresa P

    2016-01-01

    Despite research advances, work-family scholars still lack an understanding of how leadership constructs relate to an employee's ability to effectively manage the work-family interface. In addition, there remains a need to examine the process through which leadership and work-family conflict influence well-being outcomes. Using a sample of 312 workers, a mediated process model grounded in social exchange theory is tested wherein the authors seek to explain how leaders shape employee perceptions, which, in turn, impact organizational fulfillment of expectations (i.e., psychological contract breach), work-family conflict, and well-being. A fully latent structural equation model was used to test study hypotheses, all of which were supported. Building on existing theory, findings suggest that the supervisor plays a critical role as a frontline representative for the organization and that work-family conflict is reduced and well-being enhanced through a process of social exchange between the supervisor and worker.

  1. Do workaholism and work engagement predict employee well-being and performance in opposite directions?

    Shimazu, Akihito; Schaufeli, Wilmar B; Kubota, Kazumi; Kawakami, Norito

    2012-01-01

    This study investigated the distinctiveness between workaholism and work engagement by examining their longitudinal relationships (measurement interval=7 months) with well-being and performance in a sample of 1,967 Japanese employees from various occupations. Based on a previous cross-sectional study (Shimazu & Schaufeli, 2009), we expected that workaholism predicts future unwell-being (i.e., high ill-health and low life satisfaction) and poor job performance, whereas work engagement predicts future well-being (i.e., low ill-health and high life satisfaction) and superior job performance. T1-T2 changes in ill-health, life satisfaction and job performance were measured as residual scores that were then included in the structural equation model. Results showed that workaholism and work engagement were weakly and positively related to each other. In addition, workaholism was related to an increase in ill-health and to a decrease in life satisfaction. In contrast, work engagement was related to a decrease in ill-health and to increases in both life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts that are oppositely related to well-being and performance. PMID:22673364

  5. Maternal working conditions and child well-being in welfare-leaving families.

    Dunifon, Rachel; Kalil, Ariel; Bajracharya, Ashish

    2005-11-01

    In the wake of welfare reform, thousands of low-income single mothers have transitioned into the labor market. In this article, the authors examine how the work conditions of mothers leaving welfare for employment are associated with the emotional well-being of 372 children ages 5 to 15 years. The authors examine the cumulative incidence, over a 5-year period, of maternal non-family-friendly work conditions, including long work hours, erratic work schedules, nonday shifts, and lengthy commute times, in association with children's internalizing and externalizing behavior problems and levels of positive behavior. The authors found that mothers' lengthy commute times are associated with higher levels of internalizing problem behaviors and lower levels of positive behaviors. PMID:16351332

  6. Work Conditions and Health and Well-Being of Latina Hotel Housekeepers.

    Hsieh, Yu-Chin; Apostolopoulos, Yorghos; Sönmez, Sevil

    2016-06-01

    Hotel housekeepers are exposed to a plethora of disproportionately high work-induced hazards that can lead to adverse health consequences. Latina hotel housekeepers are rendered particularly vulnerable to elevated occupational hazards and resultant health strains due to their socioeconomic status, immigration status, language barriers, and lack of access to healthcare services. The findings from the 27 interviews with Latina hotel housekeepers indicated that the interviewees were exposed to physical, chemical, and social hazards in the workplace and suffered musculoskeletal injuries. In terms of psychological wellness, the time pressure of cleaning rooms quickly and work-related stress stemming from workplace mistreatment emerged as major work-related stressors. Recommendations are made for the introduction of multilevel interventions designed to prevent work-related injuries and illnesses and to promote healthier workplaces. PMID:26001842

  8. Preliminary characterization of abandoned septic tank systems. Volume 1

    This report documents the activities and findings of the Phase I Preliminary Characterization of Abandoned Septic Tank Systems. The purpose of the preliminary characterization activity was to investigate the Tiger Team abandoned septic systems (tanks and associated leachfields) for the purpose of identifying waste streams for closure at a later date. The work performed was not to fully characterize or remediate the sites. The abandoned systems potentially received wastes or effluent from buildings which could have discharged non-domestic, petroleum hydrocarbons, hazardous, radioactive and/or mixed wastes. A total of 20 sites were investigated for the preliminary characterization of identified abandoned septic systems. Of the 20 sites, 19 were located and characterized through samples collected from each tank(s) and, where applicable, associated leachfields. The abandoned septic tank systems are located in Areas 5, 12, 15, 25, and 26 on the Nevada Test Site

  9. Description of work for 200-UP-1 characterization of monitoring wells

    This description of work details the field activities associated with the drilling, soil sampling, and construction of groundwater monitoring and dual-use wells as part of the Remedial Investigation/Feasibility Study Work Plan for the 200-UP-1 Groundwater Operable Unit and will serve as a field guide for those performing the work. It will be used in conjunction with DOE-RE and Environmental Investigations and Site Characterization Manual. Groundwater wells are being constructed to characterize the vertical and horizontal extent of the Uranium and 99Tc plumes and to define aquifer properties such as hydraulic communication between aquifers and hydrostratigraphy. Some of these wells may be utilized for extraction purposes during the Interim Remedial Measures (IRM) phase anticipated at this operable unit and are being designed with a dual use in mind. These data will be used to optimize the IRM for the cleanup of these two plumes. The data will also be used with later Limited Field Investigation data to perform a Qualitative Risk Assessment for the operable unit. The locations for the proposed groundwater wells are presented. The contaminants of concern for the project are presented also

  13. W.B. Lewis Lecture: Cleaning-up abandoned uranium mines in Saskatchewan's North

    Thirty-six now-abandoned uranium mine and mill sites were developed and operated on or near Lake Athabasca, in Northern Saskatchewan, Canada, from approximately 1957 through 1964. During their operating lifetimes these mines produced large quantities of ore and tailings. After closure in the 1960's, these mine and mill sites were abandoned with little remediation and no reclamation being done. The governments of Canada and Saskatchewan are now funding the clean-up of these abandoned northern uranium mine and mill sites and have contracted the management of the project to the Saskatchewan Research Council (SRC). The clean-up activity is underway, with work at many of the smaller sites largely completed, work at the Gunnar site well underway, and a beginning made at the Lorado site. This lecture presents an overview of these operations. (author)

  18. Applying information theory to small groups assessment: emotions and well-being at work.

    García-Izquierdo, Antonio León; Moreno, Blanca; García-Izquierdo, Mariano

    2010-05-01

    This paper explores and analyzes the relations between emotions and well-being in a sample of aviation personnel, passenger crew (flight attendants). There is an increasing interest in studying the influence of emotions and its role as psychosocial factors in the work environment as they are able to act as facilitators or shock absorbers. The contrast of the theoretical models by using traditional parametric techniques requires a large sample size to the efficient estimation of the coefficients that quantify the relations between variables. Since the available sample that we have is small, the most common size in European enterprises, we used the maximum entropy principle to explore the emotions that are involved in the psychosocial risks. The analyses show that this method takes advantage of the limited information available and guarantee an optimal estimation, the results of which are coherent with theoretical models and numerous empirical researches about emotions and well-being.

  19. Consequences of fathers' participation in family work: parents' role strain and well-being.

    Baruch, G K; Barnett, R C

    1986-11-01

    The relation of fathers' participation in family work (child care and home chores) to parents' role strain and well-being was examined in an interview study of 160 Caucasian middle-class fathers and mothers of kindergarten and fourth-grade children. In half of the families, mothers were employed. Four forms of paternal participation were examined. Role-strain items referred to immediate and specific problems such as time and energy constraints and role conflicts. Well-being measures assessed self-esteem, life satisfaction, and quality of experience in the parental and marital roles. Regression analyses, carried out separately for fathers and for mothers, indicated that, contrary to expectation, when the level of fathers' participation was controlled maternal employment did not condition the relation between participation and the outcome variables. Findings varied for the different forms of participation. For fathers, higher levels of participation were associated with feeling more involved and competent as a parent and with being more critical of wives' patterns and parenting. For mothers, those whose husbands were more participant praised their husbands' parenting, but they were lower in life satisfaction and were more self-critical about their balance of work and family responsibilities.

  20. Occupational stress in submariners: the impact of isolated and confined work on psychological well-being.

    Brasher, Kate S; Dew, Angela B C; Kilminster, Shaun G; Bridger, Robert S

    2010-03-01

    This study aimed to identify work-related and personal factors associated with occupational stress in submariners. Work and well-being questionnaires were distributed to 219 male submariners (mean age 34 years), as part of a larger cohort study involving a stratified sample of 4951 Royal Navy (RN) personnel. The stress rate in submariners was 40%; significantly higher than the stress rate in the general RN, although once demographic factors were controlled for in a matched control sample, this difference was no longer significant. A summary model accounted for 49% of the variance in submariner stress, with key differences emerging between the occupational factors associated with stress in submariners and in the general RN. The longitudinal nature of this study permits stress in submariners to be monitored over 5 years, which will provide valuable insights into the chronicity of stress in this specialised occupational group. STATEMENT OF RELEVANCE: This paper contributes to the current literature on the negative impact of working in isolated conditions. It is demonstrated that occupational stress in submarines can be partially explained using current theories of stress in the workplace. However, the constraints of a restricted environment introduce additional factors which can also be associated with occupational stress. PMID:20191405

  1. Workplace-based health and wellness programs: the intersection of aging, work, and health.

    Pitt-Catsouphes, Marcie; James, Jacquelyn Boone; Matz-Costa, Christina

    2015-04-01

    Workplace-based health and wellness programs (HWPs) may be an obvious yet under-utilized strategy for promoting positive health-related behaviors among older workers and for increasing their ability to continue to work. Given the unprecedented number of older adults who extend their labor force attachment beyond traditional retirement ages, a new vision of older adults' economic security and overall quality-of-life should take into account the intersections of aging, work, and health. The purpose of this article is to: (a) discuss the workplace as an increasingly important setting that can expand the reach and effectiveness of health promotion efforts; (b) examine current knowledge of barriers and facilitators that can affect older workers' participation in workplace-based HWPs; and (c) suggest new incentive structures that may increase older workers' engagement in these programs. We develop a rationale for our proposition that sustained participation in HWPs may improve the health status of older workers and reduce health care costs. It is our conclusion that there is significant potential for workplace-based HWPs to support older adults who want to or need to work. PMID:26035602

Our study objective was to explain and quantify the impact of switching from the Kelly schedule to the 48/96 schedule by measuring changes in sleep, feelings of daytime function, as well as perceptions of professional and personal well-being for American firefighters. Sleep diaries and self-reported surveys were administered to firefighters at an urban fire department. Sleep diaries measuring the number of hours slept and feelings of refreshment were compared one month before and four months after implementation of the 48/96 schedule. The self-reported surveys measured sleepiness levels via the Epworth Sleepiness Scale. Secondary study objectives included changes in professional and personal well-being time for personal schedules, satisfaction, and health habits before and after the 48/96 schedule was implemented. The 59 firefighters included in the study reported an increase in sleep on-shift after the new schedule implementation (5.8 to 6.6 hours/night, p < 0.001. Participants also reported increased feelings of refreshment on days off (p < 0.001 and decreased daytime sleepiness (p < 0.001. We also found a general trend of improved perceptions of satisfaction, less shift interference with personal schedules and decreased feelings of burnout. American firefighters appeared to benefit from a 48/96 schedule, with short-term improvements in sleep patterns, feelings of burnout, and time for personal schedules.

    2010-11-01

    Full Text Available Abstract Background The transition from medical student to junior doctor in postgraduate training is a critical stage in career progression. We report junior doctors' views about the extent to which their medical school prepared them for their work in clinical practice. Methods Postal questionnaires were used to survey the medical graduates of 1999, 2000, 2002 and 2005, from all UK medical schools, one year after graduation, and graduates of 2000, 2002 and 2005 three years after graduation. Summary statistics, chi-squared tests, and binary logistic regression were used to analyse the results. The main outcome measure was the level of agreement that medical school had prepared the responder well for work. Results Response rate was 63.7% (11610/18216 in year one and 60.2% (8427/13997 in year three. One year after graduation, 36.3% (95% CI: 34.6, 38.0 of 1999/2000 graduates, 50.3% (48.5, 52.2 of 2002 graduates, and 58.2% (56.5, 59.9 of 2005 graduates agreed their medical school had prepared them well. Conversely, in year three agreement fell from 48.9% (47.1, 50.7 to 38.0% (36.0, 40.0 to 28.0% (26.2, 29.7. Combining cohorts at year one, percentages who agreed that they had been well prepared ranged from 82% (95% CI: 79-87 at the medical school with the highest level of agreement to 30% (25-35 at the lowest. At year three the range was 70% to 27%. Ethnicity and sex were partial predictors of doctors' level of agreement; following adjustment for them, substantial differences between schools remained. In years one and three, 30% and 34% of doctors specified that feeling unprepared had been a serious or medium-sized problem for them (only 3% in each year regarded it as serious. Conclusions The vast knowledge base of clinical practice makes full preparation impossible. Our statement about feeling prepared is simple yet discriminating and identified some substantial differences between medical schools. Medical schools need feedback from graduates about

  6. Water pollution from abandoned mines

    Iversen, E.; Johannessen, M.

    1987-01-01

    The report provides a country-wide overview of abandoned pyrite mines where operations have been fairly extensive. The water pollution situation is assessed on the basis of reported investigations, inspections and chemical analyses from the individual areas. In cases where larger watercourses (Orkla, Gaula), and the upper stretch of the Glåma are affected the situation appears to be adequately described. However abandoned mine areas may also cause local pollution problems, and here documentat...

    Major changes that emphasise the importance of a balanced work and family life have occurred within organisations. Inability to manage this integration between the work and home domains can affect the performance of organisations and the wellbeing of their employees. In order to measure work-home interaction and wellbeing, it is important to use valid, equivalent and reliable instruments. However, there is a lack of empirical research when investigating work-home interaction, b...

  9. Superconductivity in optimally doped cuprates: BZA program works well and superexchange is the glue

    G. Baskaran

    2006-09-01

    Full Text Available   Resonating valence bond states in a doped Mott insulator was proposed to explain superconductivity in cuprates in January 1987 by Anderson. A challenging task then was proving existence of this unconventional mechanism and a wealth of possibilities, with a rigor acceptable in standard condensed matter physics, in a microscopic theory and develop suitable many body techniques. Shortly, a paper by Anderson, Zou and us (BZA undertook this task and initiated a program. Three key papers that followed, shortly, essentially completed the program, as far as superconductivity is concerned,i a gauge theory approach by Anderson and us, that went beyond mean field theory ii Kotliar’s d -wave solution in BZA theory iii improvement of a renormalized Hamiltonian in BZA theory, using a Gutzwiller approximation by Zhang, Gros, Rice and Shiba. In this article I shall focus on the merits of BZA and gauge theory papers. They turned out to be a foundation for subsequent developments dealing with more aspects that were unconventional - d -wave order parameter with nodal Bogoliubov quasi particles, Affleck-Marston’s π-flux condensed spin liquid phase, unconventional spin-1 collective mode at (π, π, and other fascinating developments. Kivelson, Rokhsar and Sethna’s idea of holons and their bose condensation found expression in the slave boson formalism and lead to results similar to BZA program. At optimal doping, correlated electrons acquire sufficient fermi sea character, at the same time retain enough superexchange inherited from a Mott insulator parentage, ending in a BCS like situation with superexchange as a glue! Not surprisingly, mean field theory works well at optimal doping, even quantitatively. Further, t-J model is a minimal model only around optimal doping, where RVB superconductivity is also at its best.

  15. Estimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology

    Rafael Rodríguez Díez

    2014-07-01

    Full Text Available Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been developed for assessing the geothermal energy potential of abandoned underground coal mines, as well as for quantifying the reduction in CO2 emissions associated with using the mines instead of conventional heating/cooling technologies. On this basis the authors have been able to estimate that the geothermal energy available from underground coal mines in Europe is on the order of several thousand megawatts thermal. Although this is a gross value, it can be considered a minimum, which in itself vindicates all efforts to investigate harnessing it.

  19. The interplay of work and caregiving: relationships between role satisfaction, role involvement, and caregivers' well-being.

    Martire, L M; Stephens, M A; Atienza, A A

    1997-09-01

    This study applied theory from the general work and family literature to the dual roles of work and caregiving, in order to examine whether level of satisfaction and time involvement in each of these roles moderate the effects of stress in the other role on well-being. Respondents were 118 employed women who were providing care to an impaired parent or parent-in-law. As predicted, greater time involvement in work was found to buffer women from the negative effects of caregiving stress. Satisfaction with caregiving and satisfaction with work were directly associated with better well-being, beyond the effects of stress in both roles. However, women who experienced high levels of caregiving stress and who were highly satisfied with work were especially vulnerable to depression. These findings illustrate the importance of examining the effects of caregiving stress on well-being in the context of work-related experiences. PMID:9310100

  1. IMPACT OF PARTICIPATION IN WORKPLACE WELLNESS PROGRAMS ON QUALITY OF WORK LIFE AMONG IT EMPLOYEES IN BANGALORE

    Pramod, S. K

    2014-08-01

    Full Text Available Health is wealth. Since health is very much required for the effective functioning of an individual, it is very important to enhance and maintain it. With the increase in the amount of money spent by employers on health insurance, companies have started realising the importance of workplace wellness programs and have started taking initiative towards implementing it. Wellness programs aims at improving the overall health and with its benefits on the work life of employees, it is important to understand if these programs affect the quality of work life of wellness program participating employees. The main objective of the study was to understand the impact of participation in workplace wellness programs on quality of work life among IT employees. The researcher collected data using the Quality of Work Life Scale from a sample of 71 IT employees among 36 who participated in workplace wellness programs and others who do not. The results of the study concluded that quality of work life of employees participating in wellness programs were higher than employees who did not participate and the quality of work life of male employees participating in wellness programs were not different of that of female employees participating in wellness programs.

  2. The work-nonwork interface and well-being at work : a multi-methodological approach on stability, cross-lagged relations, and the role of interindividual differences

    Reichl, Corinna

    2013-01-01

    A large body of cross-sectional studies has thus far reported substantial correlations between work-nonwork conflict and burnout and between work-nonwork enrichment and work engagement. However, the majority of studies relied on cross-sectional study designs which further revealed a large amount of between-study variance in effect sizes. As a consequence, we lack knowledge about the true score correlations, the causality as well as about moderating variables. The present thesis was designed t...

  15. Abandonment: Technological, organisational and environmental challenges

    The paper deals with the abandonment of offshore wells. Decommissioning of offshore installations is a complex multi-disciplined issue, which raises a number of technical, organisational and environmental challenges. The success of a planned decommissioning operation depends on the development of a clear understanding of the complex blend of drivers which control the decommissioning process and their inter-relationship. Due to the complexity of the inter-relationship between the primary drivers one cannot separate the technological, organisational and environmental issues raised by the decommissioning of offshore installations. The optimal solution will be a compromise between all the decommissioning drivers mentioned in this paper. 5 figs., 3 tabs

  16. Who abandons embryos after IVF?

    Walsh, A P H

    2010-04-01

    This investigation describes features of in vitro fertilisation (IVF) patients who never returned to claim their embryos following cryopreservation. Frozen embryo data were reviewed to establish communication patterns between patient and clinic; embryos were considered abandoned when 1) an IVF patient with frozen embryo\\/s stored at our facility failed to make contact with our clinic for > 2 yrs and 2) the patient could not be located after a multi-modal outreach effort was undertaken. For these patients, telephone numbers had been disconnected and no forwarding address was available. Patient, spouse and emergency family contact\\/s all escaped detection efforts despite an exhaustive public database search including death records and Internet directory portals. From 3244 IVF cycles completed from 2000 to 2008, > or = 1 embryo was frozen in 1159 cases (35.7%). Those without correspondence for > 2 yrs accounted for 292 (25.2%) patients with frozen embryos; 281 were contacted by methods including registered (signature involving abandoned embryos did not differ substantially from other patients. The goal of having a baby was achieved by 10\\/11 patients either by spontaneous conception, adoption or IVF. One patient moved away with conception status unconfirmed. The overall rate of embryo abandonment was 11\\/1159 (< 1%) in this IVF population. Pre-IVF counselling minimises, but does not totally eliminate, the problem of abandoned embryos. As the number of abandoned embryos from IVF accumulates, their fate urgently requires clarification. We propose that clinicians develop a policy consistent with relevant Irish Constitutional provisions to address this medical dilemma.

  17. Personality, work characteristics, and employee well-being: a longitudinal analysis of additive and moderating effects.

    Houkes, Inge; Janssen, Peter P M; de Jonge, Jan; Bakker, Arnold B

    2003-01-01

    This study tested the longitudinal influence of personality (measured by the characteristics growth need strength, negative affectivity [NA], and upward striving) on 3 psychological outcomes (intrinsic work motivation, emotional exhaustion, and turnover intention), using a pattern of specific relationships between work characteristics and these outcomes as a framework. The study hypotheses were tested in a multioccupational sample consisting of bank employees and teachers, using a 2-wave panel design with a 1-year time interval and structural equation modeling. NA had a cross-lagged direct and additive relationship with emotional exhaustion and also moderated the relationship between Time 1 workload and Time 2 emotional exhaustion. The authors concluded that NA may have multiple effects on emotional exhaustion that persist over time. PMID:12553527

  10. Why the Particle-in-a-Box Model Works Well for Cyanine Dyes but Not for Conjugated Polyenes

    Autschbach, Jochen

    2007-01-01

    We investigate why the particle-in-a-box (PB) model works well for calculating the absorption wavelengths of cyanine dyes and why it does not work for conjugated polyenes. The PB model is immensely useful in the classroom, but owing to its highly approximate character there is little reason to expect that it can yield quantitative agreement with…

  12. A work-family conflict/subjective well-being process model: a test of competing theories of longitudinal effects.

    Matthews, Russell A; Wayne, Julie Holliday; Ford, Michael T

    2014-11-01

    In the present study, we examine competing predictions of stress reaction models and adaptation theories regarding the longitudinal relationship between work-family conflict and subjective well-being. Based on data from 432 participants over 3 time points with 2 lags of varying lengths (i.e., 1 month, 6 months), our findings suggest that in the short term, consistent with prior theory and research, work-family conflict is associated with poorer subjective well-being. Counter to traditional work-family predictions but consistent with adaptation theories, after accounting for concurrent levels of work-family conflict as well as past levels of subjective well-being, past exposure to work-family conflict was associated with higher levels of subjective well-being over time. Moreover, evidence was found for reverse causation in that greater subjective well-being at 1 point in time was associated with reduced work-family conflict at a subsequent point in time. Finally, the pattern of results did not vary as a function of using different temporal lags. We discuss the theoretical, research, and practical implications of our findings.

  13. Patterns and drivers of post-socialist farmland abandonment in Western Ukraine

    Baumann, Matthias; Kuemmerle, Tobias; Elbakidze, Marine;

    2011-01-01

    Farmland abandonment restructures rural landscapes in many regions worldwide in response to gradual industrialization and urbanization. In contrast, the political breakdown in Eastern Europe and the former Soviet Union triggered rapid and widespread farmland abandonment, but the spatial patterns of...... substantial spatial variation in abandonment rates. However, many of our a priori hypotheses about the direction of variable influence were rejected. Most importantly, abandonment rates were higher in the plains and lower in marginal areas. The growing importance of subsistence farming in the transition...... period, as well as off-farm income and remittances likely explain these patterns. The breakdown of socialism appears to have resulted in fundamentally different abandonment patterns in the Western Ukraine, where abandonment was a result of the institutional and economic shock, compared to those in Europe...

They have to distinguish themselves from their competitors in the market through technological advancement, market changes and the constant drive to be the best. Other demands include political pressures, e.g. employment equity and diversity management. Furthermore they have to attempt to reduce costs as well as to increase productivity. These pressures may have either a negative or positive effect on employees which could in turn impa...

  15. Leading team learning: what makes interprofessional teams learn to work well?

    Chatalalsingh, Carole; Reeves, Scott

    2014-11-01

    This article describes an ethnographic study focused on exploring leaders of team learning in well-established nephrology teams in an academic healthcare organization in Canada. Employing situational theory of leadership, the article provides details on how well established team members advance as "learning leaders". Data were gathered by ethnographic methods over a 9-month period with the members of two nephrology teams. These learning to care for the sick teams involved over 30 regulated health professionals, such as physicians, nurses, social workers, pharmacists, dietitians and other healthcare practitioners, staff, students and trainees, all of whom were collectively managing obstacles and coordinating efforts. Analysis involved an inductive thematic analysis of observations, reflections, and interview transcripts. The study indicated how well established members progress as team-learning leaders, and how they adapt to an interprofessional culture through the activities they employ to enable day-to-day learning. The article uses situational theory of leadership to generate a detailed illumination of the nature of leaders' interactions within an interprofessional context. PMID:24654793

    Dursun, Onur Burak; Sener, Mustafa Talip; Esin, Ibrahim Selcuk; Ançi, Yüksel; Yalin Sapmaz, Sermin

    2014-01-01

    Work in the field of sexual abuse is extremely stressful and may arouse negative personal reactions. Although these secondary trauma effects are well described on a personal level, there is not enough evidence to understand whether these professionals carry these effects to their homes, families, and offspring. This study aims to identify the effects of working with child abuse cases on the anxiety level and parenting styles of childhood trauma workers and on their children's well-being. A total of 43 health and legal system workers who worked with abused children in any step of their process and who had children constituted the study group, and 50 control cases, each working in the same institution and having the same occupation as 1 of the participants from the study group and having children but not working directly with children and child abuse cases, were included in the study. Participants were asked to fill out a sociodemographic form, the Parental Attitude Research Instrument, the trait portion of the State-Trait Anxiety Inventory, and an age-appropriate form of the Child Behavior Checklist for each child they had. Professionals in the study working with child abuse cases demonstrated significantly higher democratic parenting attitudes. Law enforcement workers working with child abuse cases demonstrated stricter and more authoritarian parenting strategies, as well as more democratic attitudes, than their colleagues. There was not a statistically significant relationship between child abuse workers' anxiety level and their children's well-being among control subjects. PMID:24983655

  20. Phase-sensitive radar on thick Antarctic ice - how well does it work?

    Binder, Tobias; Eisen, Olaf; Helm, Veit; Humbert, Angelika; Steinhage, Daniel

    2016-04-01

    Phase-sensitive radar (pRES) has become one of the mostly used tools to determine basal melt rates as well as vertical strain in ice sheets. Whereas most applications are performed on ice shelves, only few experiments were conducted on thick ice in Greenland or Antarctica. The technical constrains on an ice shelf to deduce basal melt rates are less demanding than on inland ice of more than 2 km thickness. First, the ice itself is usually only several 100s of meters thick; and, second, the reflection coefficient at the basal interface between sea water and ice is the second strongest one possible. Although the presence of marine ice with higher conductivities might increase attenuation in the lower parts, most experiments on shelves were successful. To transfer this technology to inland regions, either for the investigation of basal melt rates of subglacial hydrological networks or for determining vertical strain rates in basal regions, a reliable estimate of the current system performance is necessary. To this end we conducted an experiment at and in the vicinity of the EPICA deep ice core drill site EDML in Dronning Maud Land, Antarctica. That site has been explored in extraordinary detail with different geophysical methods and provides an already well-studied ice core and borehole, in particular with respect to physical properties like crystal orientation fabric, dielectric properties and matching of internal radar horizons with conductivity signals. We present data from a commercially available pRES system initially recorded in January 2015 and repeated measurements in January 2016. The pRES data are matched to existing and already depth-calibrated airborne radar data. Apart from identifying prominent internal layers, e.g. the one originating from the deposits of the Toba eruption at around 75 ka, we put special focus on the identification of the basal reflection at multiple polarizations. We discuss the potential uncertainty estimates and requirements to

  1. Localized Detection of Abandoned Luggage

    Jing-Ying Chang

    2010-01-01

    Full Text Available Abandoned luggage represents a potential threat to public safety. Identifying objects as luggage, identifying the owners of such objects, and identifying whether owners have left luggage behind are the three main problems requiring solution. This paper proposes two techniques which are “foreground-mask sampling” to detect luggage with arbitrary appearance and “selective tracking” to locate and to track owners based solely on looking only at the neighborhood of the luggage. Experimental results demonstrate that once an owner abandons luggage and leaves the scene, the alarm fires within few seconds. The average processing speed of the approach is 17.37 frames per second, which is sufficient for real world applications.

  2. How well does the Post-fire Erosion Risk Management Tool (ERMiT) really work?

    Robichaud, Peter; Elliot, William; Lewis, Sarah; Miller, Mary Ellen

    2016-04-01

    The decision of where, when, and how to apply the most effective postfire erosion mitigation treatments requires land managers to assess the risk of damaging runoff and erosion events occurring after a fire. The Erosion Risk Management Tool (ERMiT) was developed to assist post fire assessment teams identify high erosion risk areas and effectiveness of various mitigation treatments to reduce that risk. ERMiT is a web-based application that uses the Water Erosion Prediction Project (WEPP) technology to estimate erosion, in probabilistic terms, on burned and recovering forest, range, and chaparral lands with and without the application of mitigation treatments. User inputs are processed by ERMiT to combine rain event variability with spatial and temporal variabilities of hillslope burn severity and soil properties which are then used as WEPP inputs. Since 2007, the model has been used in making hundreds of land management decisions in the US and elsewhere. We use eight published field study sites in the Western US to compare ERMiT predictions to observed hillslope erosion rates. Most sites experience only a few rainfall events that produced runoff and sediment except for a California site with a Mediterranean climate. When hillslope erosion occurred, significant correlations occurred between the observed hillslope erosion and those predicted by ERMiT. Significant correlation occurred for most mitigation treatments as well as the five recovery years. These model validation results suggest reasonable estimates of probabilistic post-fire hillslope sediment delivery when compared to observation.

  3. Is workaholism good or bad for employee well-being? The distinctiveness of workaholism and work engagement among Japanese employees.

    Shimazu, Akihito; Schaufeli, Wilmar B

    2009-10-01

    The aim of the present study is to demonstrate the empirical distinctiveness of workaholism and work engagement by examining their relationships with well-being in a sample of 776 Japanese employees. We expected that workaholism is associated with unwell-being (i.e., high psychological distress and physical complaints, low job and family satisfaction, and low job performance), whereas work engagement is associated with well-being. Well-validated questionnaires were used to measure workaholism (DUWAS), work engagement (UWES), and well-being (BJSQ, HPQ). Structural Equation Modeling showed that, as expected, workaholism was positively associated with ill-health (i.e., psychological distress and physical complaints) and negatively associated with life satisfaction (i.e., job and family satisfaction) and job performance. In contrast, work engagement was negatively associated with ill-health and positively associated with life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts, which are negatively and positively related to various indicators of well-being, respectively.

  6. Seasonal energy storage using bioenergy production from abandoned croplands

    Bioenergy has the unique potential to provide a dispatchable and carbon-negative component to renewable energy portfolios. However, the sustainability, spatial distribution, and capacity for bioenergy are critically dependent on highly uncertain land-use impacts of biomass agriculture. Biomass cultivation on abandoned agriculture lands is thought to reduce land-use impacts relative to biomass production on currently used croplands. While coarse global estimates of abandoned agriculture lands have been used for large-scale bioenergy assessments, more practical technological and policy applications will require regional, high-resolution information on land availability. Here, we present US county-level estimates of the magnitude and distribution of abandoned cropland and potential bioenergy production on this land using remote sensing data, agriculture inventories, and land-use modeling. These abandoned land estimates are 61% larger than previous estimates for the US, mainly due to the coarse resolution of data applied in previous studies. We apply the land availability results to consider the capacity of biomass electricity to meet the seasonal energy storage requirement in a national energy system that is dominated by wind and solar electricity production. Bioenergy from abandoned croplands can supply most of the seasonal storage needs for a range of energy production scenarios, regions, and biomass yield estimates. These data provide the basis for further down-scaling using models of spatially gridded land-use areas as well as a range of applications for the exploration of bioenergy sustainability. (letter)

  8. The importance of autonomy support and the mediating role of work motivation for well-being: testing self-determination theory in a Chinese work organisation.

    Nie, Youyan; Chua, Bee Leng; Yeung, Alexander Seeshing; Ryan, Richard M; Chan, Wai Yen

    2015-08-01

    We examine relations between perceived organisational autonomy support and different types of work motivation and well-being outcomes in 266 teachers from two government schools in China. We hypothesised that greater autonomy support would be associated with more autonomous forms of employee motivation, and that teacher motivation would in turn mediate the effects of autonomy support on indicators of work well-being (i.e., job satisfaction, work stress and physical ill symptoms). Results generally supported the hypothesised relations between perceived autonomy support and SDT's five types of motivations. Findings also showed that perceived autonomy support predicted job satisfaction directly and indirectly through the mediating roles of intrinsic motivation, identified regulation, introjected regulation and external regulation. Perceived autonomy support predicted work stress directly and indirectly through the mediating roles of external regulation and amotivation. Autonomy support also predicted illness symptoms via the mediating roles of intrinsic motivation, introjected regulation and amotivation. The current findings highlight how perceived organisational support for autonomy relates to motivational differences in a Chinese work context, and the potential relevance of autonomy support for employee well-being.

  9. Work-related stress and well-being: the roles of direct action coping and palliative coping.

    Fortes-Ferreira, Lina; Peiró, José M; González-Morales, M Gloria; Martín, Isabel

    2006-08-01

    The purpose of the present study is to analyze the roles of direct action coping and palliative coping in the relationship between work stressors and psychological well-being, as well as their possible interactions, in a sample of 464 bank employees. Hierarchical regression analyses showed main effects of direct action coping on well-being. Palliative coping predicts higher levels of psychological distress. Contrary to what was expected, the interactions between work stressors and direct action coping were not significant. Palliative coping interacted with work stressors when predicting psychosomatic complaints. The interaction between the two types of coping was significant on psychosomatic complaints and psychological distress, but not on job satisfaction. The paper discusses theoretical and practical implications of these results, in order to design intervention strategies to prevent and manage job stress. PMID:16869862

  18. Inequalities in the psychological well-being of employed, single and partnered mothers: the role of psychosocial work quality and work-family conflict

    Muhajarine Nazeem

    2010-02-01

    Full Text Available Abstract Background A large body of international research reveals that single mothers experience poorer mental health than their partnered counterparts, with socioeconomic disadvantage identified as an important contributory factor in understanding this health disparity. Much less research, however, has focused specifically on the psychological well-being of single mothers who are employed, despite their growing presence in the labor force. Of the research which has considered employment, the focus has been on employment status per se rather than on other important work-related factors which may impact psychological health, such as psychosocial work quality and work-family conflict. The aim of this study was to: (1 compare employed single mothers and employed partnered mothers on measures of psychological distress, psychosocial work quality and work-family conflict; and (2 explore the potential role of work-family conflict and psychosocial work quality as explanations for any observed differences in psychological distress based on partner status. Method Analysis of data obtained from a cross-sectional telephone survey of employed parents in a mid-sized Western Canadian city. Analyses were based on 674 employed mothers (438 partnered and 236 single, who were 25-50 years old, with at least one child in the household. Results Compared to employed single mothers, employed partnered mothers were older, had more education and reported fewer hours of paid work. Single mothers reported higher levels of psychological distress, financial hardship, work-family conflict and poor psychosocial work quality. Statistical adjustment for income adequacy, psychosocial work quality and work-family conflict each independently resulted in single motherhood no longer being associated with psychological distress. Conclusions While single employed mothers did experience higher levels of psychological distress than their partnered counterparts, differences between these

  2. Frequent short rest breaks from computer work: effects on productivity and well-being at two field sites.

    Henning, R A; Jacques, P; Kissel, G V; Sullivan, A B; Alteras-Webb, S M

    1997-01-01

    Computer operators at two work sites (n = 73, n = 19) were prompted to take three 30-s and one 3-min break from computer work each hour in addition to conventional rest breaks. Some operators were asked to perform stretching exercises during the short breaks. Mood state and musculoskeletal discomfort were assessed at each work site over a 2- or 3-week baseline period and a 4- or 6-week treatment period, respectively. Operator productivity measures were obtained from company records. Operators complied with about half of the added breaks but favoured 3-min breaks over 30-s breaks. No improvement in productivity or well-being was found at the larger work site. At the smaller work site, productivity, eye, leg and foot comfort all improved when the short breaks included stretching exercises. These results provide evidence that frequent short breaks from continuous computer-mediated work can benefit worker productivity and well-being when the breaks integrate with task demands.

  3. The Life of Meaning: A Model of the Positive Contributions to Well-Being from Veterinary Work.

    Cake, Martin A; Bell, Melinda A; Bickley, Naomi; Bartram, David J

    2015-01-01

    We present a veterinary model of work-derived well-being, and argue that educators should not only present a (potentially self-fulfilling) stress management model of future wellness, but also balance this with a positive psychology-based approach depicting a veterinary career as a richly generative source of satisfaction and fulfillment. A review of known sources of satisfaction for veterinarians finds them to be based mostly in meaningful purpose, relationships, and personal growth. This positions veterinary well-being within the tradition of eudaimonia, an ancient concept of achieving one's best possible self, and a term increasingly employed to describe well-being derived from living a life that is engaging, meaningful, and deeply fulfilling. The theory of eudaimonia for workplace well-being should inform development of personal resources that foster resilience in undergraduate and graduate veterinarians. PMID:26075621

  4. NEW PRINCIPLES OF WORK AND ENERGY AS WELL AS POWER AND ENERGY RATE FOR CONTINUUM FIELD THEORIES

    戴天民

    2001-01-01

    New principles of work and energy as well as power and energy rate with cross terms for polar and nonlocal polar continuum field theories were presented and from them all corresponding equations of motion and boundary conditions as well as complete equations of energy and energy rate with the help of generalized Piola' s theorems were naturally derived in all and without any additional requirement. Finally, some new balance laws of energy and energy rate for generalized continuum mechanics were established. The new principles of work and energy as well as power and energy rate with cross terms presented in this paper are believed to be new and they have corrected the incompleteness of all existing corresponding principles and laws without cross terms in literatures of generalized continuum field theories.

  5. Multiple factors drive regional agricultural abandonment.

    Osawa, Takeshi; Kohyama, Kazunori; Mitsuhashi, Hiromune

    2016-01-15

    An understanding of land-use change and its drivers in agroecosystems is important when developing adaptations to future environmental and socioeconomic pressures. Agricultural abandonment occurs worldwide with multiple potentially positive and negative consequences; however, the main factors causing agricultural abandonment in a country i.e., at the macro scale, have not been identified. We hypothesized that socio-environmental factors driving agricultural abandonment could be summarized comprehensively into two, namely "natural" and "social", and the relative importance of these differs among regions. To test this postulate, we analyzed the factors currently leading to agricultural abandonment considering ten natural environment variables (e.g., temperature) and five social variables (e.g., number of farmers) using the random forest machine learning method after dividing Japan into eight regions. Our results showed that agricultural abandonment was driven by various socio-environmental factors, and the main factors leading to agricultural abandonment differed among regions, especially in Hokkaido in northern Japan. Hokkaido has a relatively large area of concentrated farmland, and abandonment might have resulted from the effectiveness of cultivation under specific climate factors, whereas the other regions have relatively small areas of farmland with many elderly part-time farmers. In such regions, abandonment might have been caused by the decreasing numbers of potential farmers. Thus, two different drivers of agricultural abandonment were found: inefficient cultivation and decreasing numbers of farmers. Therefore, agricultural abandonment cannot be prevented by adopting a single method or policy. Agricultural abandonment is a significant problem not only for food production but also for several ecosystem services. Governments and decision-makers should develop effective strategies to prevent further abandonment to ensure sustainable future management of agro

    Widespread cropland abandonment occurred after the collapse of socialism across the former Soviet Union, but the rates and spatial patterns of abandoned lands are not well known. As a result, the potential of this region to contribute to global food production and estimates of the carbon sink developing on currently idle lands are highly uncertain. We developed a spatial allocation model that distributes yearly and subnational sown area statistics to the most agriculturally suitable plots. This approach resulted in new, high-resolution (1 km2) annual time series of cropland and abandoned lands in European Russia, Ukraine, and Belarus from 1990 to 2009. A quantitative validation of the cropland map confirms the reliability of this data set, especially for the most important agricultural areas of the study region. Overall, we found a total of 87 Mha of cropland and 31 Mha of abandoned cropland in European Russia, Ukraine, and Belarus combined, suggesting that abandonment has been severely underestimated in the past. The abandonment rates were highest in European Russia. Feeding our new map data set into the dynamic vegetation model LPJmL revealed that cropland abandonment resulted in a net carbon sink of 470 TgC for 1990 to 2009. Carbon sequestration was generally slow in the early years after abandonment, but carbon uptake increased significantly after approximately 10 years. Recultivation of older abandoned lands would be associated with high carbon emissions and lead to substantial amounts of carbon not being sequestered in vegetation formations currently developing on idle croplands. Our spatially and temporally explicit cropland abandonment data improve the estimation of trade-offs involved in reclaiming abandoned croplands and thus in increasing agricultural production in this globally important agricultural region.

    Full Text Available INTRODUCTION: Musculoskeletal pain is one of the most frequent complaints among teachers, compromising their health and quality of life.OBJECTIVE: To estimate the prevalence of musculoskeletal pain among teachers, assessing their occurrence according to sociodemographic characteristics, general health and well-being at work.METHODS: An exploratory cross-sectional study conducted with 525 teachers. During activities of continuing education, the teachers completed a self-administered questionnaire containing questions about sociodemographic factors, general health, well-being at work and musculoskeletal pain.RESULTS: The overall prevalence of musculoskeletal pain was equal to 73.5%. The most common musculoskeletal pains were localized in the shoulders (31.6%, upper back (27.8%, neck (27.2% and ankles and/or feet (24.0%. Circulatory and respiratory problems and Common Mental Disorders were associated with pain in the shoulders, upper back, neck and ankles and/or feet. Well- being at work is associated with pain in the shoulders, neck and ankles and/or feet.CONCLUSION: It is necessary to deepen the knowledge about musculoskeletal pain among teachers, exploring the biological, ergonomic, occupational and psychosocial mechanisms of teaching, as well as invest in practices that improve the relationship of coexistence between workers and activities that enhance the comfort and reduce referred pain.

  8. Organizational Justice and Perceived Organizational Support: Impact on Negative Work-Home Interference and Well-being Outcomes

    2015-10-01

    Full Text Available It is well established that negative work-home interference (NegWHI impacts upon several work attitudes and behaviors. In the interests of both organizational effectiveness and employee well-being, it is important to identify concepts related to NegWHI and investigate their effects on well-being outcomes. This study examines the mediating role of (1 perceived organizational support (POS in the relationship between organizational justice (OJ and NegWHI; and (2 NegWHI in the relationships between POS and four well-being outcomes. A total of 509 employees of a Belgian hospital were surveyed. Data were analyzed using structural equation modeling and the bootstrapping method. Results showed that POS partially mediates the relationships between distributive and passive procedural justice and NegWHI, and fully mediates the relationship between the other justice dimensions and NegWHI. NegWHI partially mediates the relationships between POS and both job satisfaction and intention to quit, and fully mediates the relationship between POS and job strain. Furthermore, POS is positively related to job engagement. This study showed that organizations can help employees to better manage their work and family lives and reduce the impact of NegWHI by enhancing employees’ feeling that they are supported by their organization. In order to increase POS, organizations need to promote justice in the workplace.

  10. Deriving Requirements for Pervasive Well-Being Technology From Work Stress and Intervention Theory: Framework and Case Study

    Koldijk, Saskia; Kraaij, Wessel

    2016-01-01

    Background Stress in office environments is a big concern, often leading to burn-out. New technologies are emerging, such as easily available sensors, contextual reasoning, and electronic coaching (e-coaching) apps. In the Smart Reasoning for Well-being at Home and at Work (SWELL) project, we explore the potential of using such new pervasive technologies to provide support for the self-management of well-being, with a focus on individuals' stress-coping. Ideally, these new pervasive systems should be grounded in existing work stress and intervention theory. However, there is a large diversity of theories and they hardly provide explicit directions for technology design. Objective The aim of this paper is to present a comprehensive and concise framework that can be used to design pervasive technologies that support knowledge workers to decrease stress. Methods Based on a literature study we identify concepts relevant to well-being at work and select different work stress models to find causes of work stress that can be addressed. From a technical perspective, we then describe how sensors can be used to infer stress and the context in which it appears, and use intervention theory to further specify interventions that can be provided by means of pervasive technology. Results The resulting general framework relates several relevant theories: we relate “engagement and burn-out” to “stress”, and describe how relevant aspects can be quantified by means of sensors. We also outline underlying causes of work stress and how these can be addressed with interventions, in particular utilizing new technologies integrating behavioral change theory. Based upon this framework we were able to derive requirements for our case study, the pervasive SWELL system, and we implemented two prototypes. Small-scale user studies proved the value of the derived technology-supported interventions. Conclusions The presented framework can be used to systematically develop theory

  11. Radioactive pollution investigation and disposal of abandoned uranium mines in Jiangsu province

    The environment influence of five abandoned uranium mines in Jiangsu province from 1950s to 1960s is introduced. By monitoring air absorbed dose rate of external exposure γ radiation, it is found that the pollution scope of No.1 abandoned uranium mine is the biggest in five abandoned uranium mines. The No. 2 and No. 3 mine areas has achieved the limit use after they were desposed. The radioactivity and the gamma nuclein in solid samples(slag, soil, silt) and liquid samples (the surface water, the well water)of No. 1 abandoned uranium mine were further analyzed and measured, the measured values are higher. The pollution of abandoned uranium mines still exists and diffuses after 30 years. According to the monitoring results and the analysis of pollution present situation, suggestions and measures are proposed for the pollution control. (authors)

  13. Work life and mental well-being: single and coupled employed mothers in Southern Europe and Scandinavia.

    Bull, Torill

    2009-09-01

    Many European mothers, single and coupled, combine work outside the home and family life. The effects of this on their mental well-being may vary depending on the level of support available from the State's welfare system, since welfare may buffer working mothers from some of the stress that can arise from trying to manage significant responsibilities on the job and at home. Welfare may be especially important for single working mothers, for whom the burden of multiple roles may be even heavier. The present study assessed levels and predictors of well-being of single and coupled employed mothers in Greece, Portugal and Spain, where welfare support is relatively limited. Results were compared to a parallel study with data from Denmark, Norway and Sweden, where welfare support is relatively comprehensive. Coupled mothers in Scandinavia had significantly lower financial hardship, longer education, higher life satisfaction, more enriching jobs, practical support, financial support and social participation than coupled mothers in the Southern European sample. On the other hand, the Scandinavian coupled mothers had higher levels of work family conflict than coupled mothers in Southern Europe. Single mothers in Scandinavia, compared to single mothers in Southern Europe, had significantly longer education, higher life satisfaction and positive affect, more enriching jobs, confidant support, practical support, financial support and social participation. Level of job stress was the same for all mother groups. All groups differed significantly from each other in level of financial hardship, with Scandinavian coupled mothers being best off, followed by Scandinavian single mothers, Southern European coupled mothers, and Southern European single mothers. The regional differences suggest that single motherhood per se need not be a risk factor for poorer well-being, and that welfare policies may have a protective effect for the mental well-being of single mothers.

    LaFreniere, L. M.

    2006-07-11

    This ''Work Plan'' outlines the scope of work for a targeted groundwater sampling investigation and monitoring well installation at Barnes, Kansas. This activity is being conducted at the request of the Kansas Department of Health and Environment (KDHE), in accordance with the intergovernmental agreement between the KDHE and the Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA). Data resulting from the proposed work will be used to determine the hydraulic gradient near the former CCC/USDA facility, delineate the downgradient carbon tetrachloride plume, and determine additional monitoring requirements at Barnes. The overall goal is to establish criteria for monitoring leading to potential site reclassification. The proposed work will be performed on behalf of the CCC/USDA by the Environmental Science Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The Farm Service Agency of the USDA has entered into an interagency agreement with DOE, under which Argonne provides technical assistance with environmental site characterization and remediation at former CCC/USDA grain storage facilities. Argonne issued a ''Master Work Plan'' (Argonne 2002) to provide general guidance for all investigations at former CCC/USDA facilities in Kansas. The ''Master Work Plan'', approved by the KDHE, contains the materials common to investigations at all locations in Kansas. This document must be consulted for the complete details of plans for this work associated with the former CCC/USDA facility at Barnes.

  17. The Abandonment of an Active Lifestyle Within University Students: Reasons for Abandonment and Expectations of Re-Engagement

    Manuel Gómez-López

    2011-08-01

    Full Text Available The objective of this research is to analyse in detail the barriers that make university students abandon the practice of physical activity and adopt a sedentary lifestyle. In order to do so, a questionnaire on the analysis of sports habits and lifestyles was administered to 795 students who stated not having done any physical and/or sports activity for at least one year at the moment of the field-work. A factorial, descriptive and correlation analysis was carried out. The results reveal that university students abandon a healthy lifestyle mainly due to external barriers particularly because of lack of time. On the one hand, women appear to be the ones who, to a great extent, adopt a sedentary lifestyle. On the other hand, men are the ones who refer more to abandoning the practice of physical activity due to internal barriers. The majority of the university students gave up practicing sport before entering university alluding to external barriers as their reason for the abandonment. A greater part of the sedentary university students expressing that they will be active in the future, left the practice of sport due to internal barriers.

    Background: Physical activity (PA) includes muscle activity during exercise, manual work, and leisure time activities including sport. Conflicting results exist regarding health effects of PA that may deteriorate with manual work and elite sports, but improve when performed in moderation in accordance with international guidelines and may additionally enhance well-being and productivity. Methods: In Denmark 15 randomized controlled trials have been conducted, introducing exercise at the workplace enrolling>3500 workers. The interventions lasted from 10 to 52 weeks and offered~1 h weekly supervised exercise during working hours according to the concept of intelligent physical exercise training (IPET) that is based on evidenced sports sciences training principles and tailored to work exposure, employee health status, and physical capacity. Questionnaire surveys and health checks including blood and muscle sampling were performed at baseline and follow-up. The job groups included: office and computer workers, dentists, industrial technicians, cleaning personnel, health care workers, construction workers, and fighter/helicopter pilots. Results: In all job groups significant improvements were documented regarding health outcomes. These were job group specific:neck pain was reduced among office and computer workers, dentists, industrial laboratory technicians, health care workers as well as fighter pilots. Cardio-respiratory fitness—a health risk indicator for cardio-metabolic diseases—was improved among office and computer workers, health care workers, and construction workers. Additionally, other improvements were evidenced such as increased muscle strength and balance control. Importantly, productivity increased with improved muscle strength and decreased body mass index. Conclusion: IPET does enhance health if an exercise program with evidenced efficacy is implemented by expert trainees with support of the employer. Accordingly, in every study group outcomes of

  4. Polarization signatures for abandoned agricultural fields in the Manix Basin area of the Mojave Desert - Can polarimetric SAR detect desertification?

    Ray, Terrill W.; Farr, Tom G.; Van Zyl, Jakob J.

    1992-01-01

    Radar backscatter from abandoned circular alfalfa fields in the Manix Basin area of the Mojave desert shows systematic changes with length of abandonment. The obliteration of circular planting rows by surface processes could account for the disappearance of bright spokes, which seem to be reflection patterns from remnants of the planting rows, with increasing length of abandonment. An observed shift in the location of the maximum L-band copolarization return away from VV, as well as an increase in surface roughness, both occurring with increasing age of abandonment, seems to be attributable to the formation of wind ripples on the relatively vegetationless fields.

  7. Abandonment terraced hillside and answer of the fire system: some results from Mediterranean old fields

    The abandonment of agricultural lands promotes temporal changes both in soil characteristics (i.e., increasing organic matter and other quality indicators) and in plant community (i.e., changing its composition and structure, and increasing the fuel load). As a consequence, we can expect differences in the resilience to fire as succession progresses. The aim of this work is to analyse the capacity of an ecosystem to return to pre-fire conditions as a function of the stage of abandonment of old agricultural lands. The study was carried out in the north of Alicante province (E Spain). In long-term abandoned lands, post-fire modulated plant response, which in turn determined soil crusting, runoff and erosion dynamics. In recently-abandoned lands, the plant community seemed less dependent on ratio to recover. Results show a large increase in soil surface crusting in the short term after the fire and it remained high at medium term in long-abandoned lands colonised by pine forest. Fire scarcely modified runoff and erosion in recently-abandoned lands whereas in forest lands the post-fire values increased by some orders of magnitude and remained highly dependent on rain characteristics in the short and medium term after the fire. The results obtained show evidence of increased vulnerability to fire in long-abandoned lands colonised by pine forests. (Author) 4 refs.

  8. Work plan for ground water elevation data recorder/monitor well installation at Gunnison, Colorado. Revision 1

    The purpose of this document is to describe the work that will be performed and the procedures that will be followed during installation of ground water monitor wells and ground water elevation data recorders (data loggers) at the Gunnison, Colorado, Uranium Mill Tailings Remedial Action (UMTRA) Project site. The monitor wells and data loggers will be used to gather required time-dependent data to investigate the interaction between ground water and surface water in the area. Data collection objectives (DCO) identify reasons for collecting data. The following are DCOs for the Gunnison ground water elevation data recorder/monitor well installation project: long-term continuous ground water level data and periodic ground water samples will be collected to better understand the relationship between surface and ground water at the site; water level and water quality data will eventually be used in future ground water modeling to more firmly establish numerical model boundary conditions in the vicinity of the Gunnison processing site; and modeling results will be used to demonstrate and document the potential remedial alternative of natural flushing

  9. Estimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology

    Rafael Rodríguez Díez; María B. Díaz-Aguado

    2008-05-01

    Findings are reported from a study of an innovative Multiple Heritage Service in Sheffield (UK) which provides, inter alia, individual mentoring for young people and school-based group sessions on cultural heritage, dealing with racism and enhancing well-being. Group work, undertaken between November 2005 and December 2006, was evaluated by a before/after design with 43 children aged from 8 to 15 attending five different groups (response rate 77%), using three well-established and validated measures. There were improvements on the Rosenberg Self-esteem Scale from 31.4 to 33.0 (P = 0.005) with more improvement among younger children and boys (P = 0.004 and P = 0.001); and well-being as measured by the GHQ12 improved from 1.5 to 0.8 (P = 0.111) with more improvement among older children (P = 0.026). On the third measure of problem behaviour (the Strengths and Difficulties Questionnaire), there was an improvement from 12.4 to 12.1 (P = 0.716), but there was no improvement at all for girls. Mentoring was evaluated by telephone interviews between June and October 2006 with 14 mothers whose children had just completed, or were nearing completion of, mentoring (response rate 70%). Overall, the mothers' evaluations were highly positive: two-thirds commended the service on the positive impact on their children's well-being and happiness (including all the mothers of daughters); a half reported positive impacts on identity; mothers commended the positive role model effect same-sex mentors had on their children's behaviour; but only a third said mentoring had boosted their children's self-esteem.

    Nagasawa, Miho; Mogi, Kazutaka; Kikusui, Takefumi

    2012-01-01

    In Fukushima, Japan, a prolonged refugee situation caused by a major nuclear incident after the earthquake of March 11, 2011 has led to the unintentional abandonment of many pets. We received stray or abandoned dogs from rescue centers in Fukushima Prefecture. During re-socialization training and health care, we accessed the behavioral characteristics and the urine cortisol level of each dog and compared them with those of other abandoned dogs not involved in this earthquake. The dogs from Fukushima showed significantly lower aggression toward unfamiliar people, trainability, and attachment to their caretakers; also, urine cortisol levels in the dogs from Fukushima were 5-10-fold higher than those in abandoned dogs from another area of Japan. These results suggested that the dogs from Fukushima suffered through an extremely stressful crisis. PMID:23061007

    2013-04-01

    Full Text Available The aim of the work is to evaluate the spatial distribution of Hg in the soil-plant system within an area where intense activity of Hg was dominant over a long period. An abandoned metallurgical plant from the 17th-18th centuries was chosen as the study area. It is situated in Almadenejos within the Almadén mining district (Spain that constitutes the largest and most unusual concentration of mercury in the world and has provided a third of the entire world production of mercury (Hg. Nowadays, this study area is covered with cinnabar mine tailings and village habitants use it for livestock. The area has elevated Hg concentrations of natural origin and from human activities. Soil parameters are similar throughout the study area; however, data reveal high variability in total and available Hg concentrations in soils, making it difficult to establish a tendency. Marrubium vulgare L.has been studied due to its high presence in the field plot, and there is no evidence of phenological toxicity. Furthermore, in spite of elevated Hg concentrations, a good biological activity is tested in the soil samples. All these characteristics, spatial variation, high Hg concentration, good biological activity, enhance the peculiarity of the study area for studies involving Hg.

    2015-12-01

    Full Text Available Physician-patient relationship is unique in some aspects and not-so-unique in other aspects when compared to other human interactions. Until-unless for the sake of health promotional activities, this relationship is almost always conceived in the times of human sufferings and consequently culminated when those sufferings have subsided as well as sought out happiness has ensued/been achieved. However, not all physician-patient relationships follow the normal course and/or meet the natural ends. These abnormal relationships are not inconsequential in terms of numbers and/or their effects (short-term and long term on both patients and physicians. Every country has its own baggage in the wake of why, how and what about these abnormal ends to physician-patient relationships; however, the most common causes are the patients’ inability to pay their medical bills, the conflicting goals of physicians and their patients in regards to patients’ sufferings’ management and finally the behavioral issues (patients’ and/or physicians’ interfering these relationships. Irrespective of any cause, the physicians should never forget that the patient can always discharge their physicians and discontinue their relationship with their physicians without any reason (until unless the physicians deem those patients either incapable/non-consentable to do so and/or potential threat to their own personal safety or other people’s safety. Contrarily, physicians can also discharge patients from their care but cannot abandon these patients (1-3 which mean that physicians have to ensure their discharged patients either are referred to or have sought another physician within appropriate time frame post-relationship-discontinuation. Each country has their own medico-legal liabilities that vary in terms of penalties imposed; however, irrespective of the feared legal concerns, the physicians should not forget that ethical essence of medicine is the art of healing that

  2. A Special Application Coiled Tubing Applied Plug for Geothermal Well Casing Remediation

    Casing deformation in wells is a common problem in many geothermal fields. Casing remediation is necessary to keep wells in production and occasionally, to even enter the well for an approved plug and abandonment procedure. The costly alternative to casing remediation is to incur the expense of drilling a new well to maintain production or drilling a well to intersect a badly damaged well below the deformation for abandonment purposes. The U.S. Department of Energy and the Geothermal Drilling Organization sponsor research and development work at Sandia National Laboratories in an effort to reduce these remediation expenditures. Sandia, in cooperation with Halliburton Energy Services, has developed a low cost, commercially available, bridge-plug-type packer for use in geothermal well environments. This report documents the development and testing of this tool for use in casing remediation work

  3. "I no longer believe": did Freud abandon the seduction theory?

    Ahbel-Rappe, Karin

    2006-01-01

    Recent accounts of the seduction theory and the question of its abandonment have emphasized the continuity of Freud's work before and after the seduction theory, claiming that Freud did not abandon his concern with the event of seduction but rather came to appreciate that an understanding of fantasy was also essential. This claim is challenged. It is shown that Freud did abandon the passionate concerns of his seduction theory for the most part; that he left behind his early interest in reconstructing unconscious infantile incest and focused instead on later, conscious seduction; that he at times clearly reduced apparent paternal incest to fantasy; that he turned away from the phenomenology of incest he had begun to develop; and that he theoretically nullified the value of the difference between real and fantasied seduction. It is also shown that, contrary to a persistent concern in psychoanalytic history, attention to actual seduction need not detract from the essential psychoanalytic concern with fantasy and infantile sexuality. Thinking about incest specifically illuminates the capacity for fantasizing, the core of the Freudian psyche. In this way the intuition of the seduction theory that there is something of distinctive psychoanalytic significance about incest finds support. PMID:16602351

  6. Abandoning of mining activities - impact on ground water and surface water systems

    At present a decrease in mining activities occurs in practically all mining areas (both coal and ore) in the Czech Republic. Huge capacities of mine workings in various depths and geological conditions are abandoned and liquidated. Special methods of liquidation of abandoned mine workings by filling, using selected waste as secondary raw materials, are used only exceptionally. In such cases the liquidation proceeds without problems with serious or long-term contamination of the environment, including monitoring of anomalous geomechanical events, ascent of methane to the surface etc. This systematic approach has only one negative feature - prolongation of liquidation works in comparison to simple abandoning and flooding of the mine. This contribution deals with the general aspects of groundwater protection in connection with liquidation of mines by filling of mine workings with secondary raw materials (including legislative problems in Czech Republic). 10 refs., 2 figs

  7. Effects of Weather Variability on Crop Abandonment

    Kelvin Mulungu

    2015-03-01

    Full Text Available In Zambia, every year some parts of the maize fields are abandoned post-planting. Reasons for this are not clearly known. In this paper, we examine the influence of soil and climatic factors on crop abandonment using a six-year (2007–2012 panel data by modeling the planted-to-harvested ratio (a good indicator of crop abandonment using a fractional and linear approach. Therefore, for the first time, our study appropriately (as supported by the model specification tests that favour fractional probit over linear models the fractional nature of crop abandonment. Regression results, which are not very different between the two specifications, indicate that, more than anything, high rainfall immediately after planting and inadequate fertilizer are the leading determinants of crop abandonment. In the agro-ecological region where dry planting takes place, low temperature during planting months negatively affects the harvested area. The results have implications on the sustainability of farming systems in the face of a changing climate.

  8. History of abandoned infants in Greece

    2010-01-01

    Full Text Available It is since mythology to classical ages in Greece, since Medieval Ages to the end of the 19th century in Smyrna and in Athens, that history indicates the abandonment of the infants as a phenomenon always existing. A time flashback and the research of the phenomenon through the historic examples contribute unequivocally to the remonstrance of the social facts in each era.Aim: The aim of this study was to critically review all the historical data and the evidence from the international and Greek literature and to explore the factors that are accountable for to the infant’s abandonment and especially in Greece.Method: A critical literature search was performed using of MEDLINE and CINAHL (1990-2008 databases. The literature review referred to historical data related to the care of the abandoned infants since ancient Greek times.Conclusion: The literature review leads to the conclusion that the detection of the historical sources combines a “mosaic” which reflects the multiple needs of the Greek society, with target to encounter the infant abandonment. The ways used each time in order the phenomenon to be faced, not rarely were doubted. Still they stand as the salutary solutions for the abandoned infants and they are explained and established through the social background of each era and through the needs serviced each time.

  9. NEWBORNS ABANDONMENT: THE DYNAMICS OF THE PROBLEM AND ITS RELEVANCE IN MODERN RUSSIA

    Baleeva K. I.

    2015-09-01

    Full Text Available The problem of newborns abandonment in modern Russia is relevant but understudied. This article discusses the nature and dynamics of the problem. Newborns abandonment is considered in the framework of social and demographic modernization. The problem of newborns abandonment is studied in the context of social orphanhood in Russia. The author focuses on the history of the problem of newborns abandonment, its features in pre-revolutionary Russia, the Soviet Union and modern Russia. For a deeper understanding of the problem the author held a series of expert interviews and highlighted the main factors that influenced newborns abandonment in Soviet and post-Soviet Russia. The main challenges in the development of prevention in modern Russia are identified. The author concludes on the need to reform the system for preventing newborns abandonment as part of the ideology of the family-centered approach and constructing a unified federal structure. The paper uses qualitative methods: literature review, expert interviews. The article may be of interest to specialists in the field of social work, sociology, demography, politics, and economics

  10. Abandonment, Ecological Assembly and Public Health Risks in Counter-Urbanizing Cities

    Alexandra Gulachenski

    2016-05-01

    Full Text Available Urban landscapes can be transformed by widespread abandonment from population and economic decline. Ecological assembly, sometimes referred to as “greening”, following abandonment can yield valuable ecosystem services, but also can pose a risk to public health. Abandonment can elevate zoonotic vector-borne disease risk by favoring the hyperabundance of commensal pests and pathogen vectors. Though greater biodiversity in abandoned areas can potentially dilute vector-borne pathogen transmission, “greening” can elevate transmission risk by increasing movement of pathogen vectors between fragmented areas and by giving rise to novel human-wildlife interfaces. Idled and derelict infrastructure can further elevate disease risk from vector-borne and water-borne pathogens, which can build up in stagnant and unprotected water that maintenance and routine use of delivery or sanitation systems would otherwise eliminate. Thus, framing “greening” as inherently positive could result in policies and actions that unintentionally exacerbate inequalities by elevating risks rather than delivering benefits. As counter-urbanism is neither a minor pattern of urban development, nor a short-term departure from urban growth, homeowner and municipal management of abandoned areas should account for potential hazards to reduce health risks. Further socioecological assessments of public health risks following abandonment could better ensure the resilience and well-being of communities in shrinking cities.

    2014-10-01

    Infant abandonment and infanticide are poorly understood in Malaysia. The information available in the public arena comes predominantly from anecdotal sources. The aim of this study was to describe the prevalence and characteristics of infanticide and illegal infant abandonment in Malaysia and to estimate annual rates for the most recent decade. Summaries of data about infanticide and illegal infant abandonment were gathered from police records; the annual number of live births was ascertained from the national registry. The estimated inferred infanticide rates for Malaysia were compared with the infanticide rates among countries of very high, high, medium, and low rankings on the Human Development, Gender Inequality, and Gini indices. From 1999 to 2011, 1,069 cases of illegal infant abandonment were recorded and 1,147 people were arrested as suspected perpetrators. The estimated inferred infanticide rate fluctuated between 4.82 and 9.11 per 100,000 live births, a moderate rate relative to the infanticide rates of other countries. There are substantial missing data, with details undocumented for about 78-87% of cases and suspected perpetrators. Of the documented cases, it appeared that more boys than girls were victims and that suspected perpetrators were predominantly Malays who were women, usually mothers of the victim; the possibility of arrest bias must be acknowledged. Economic and social inequality, particularly gender inequality, might contribute to the phenomena of infanticide and abandonment. Strategies to reduce rates of infanticide and illegal infant abandonment in Malaysia will require strengthening of the surveillance system and attention to the gender-based inequalities that underpin human development.

  12. Mapping the extent of abandoned farmland in Central and Eastern Europe using MODIS time series satellite data

    The demand for agricultural products continues to grow rapidly, but further agricultural expansion entails substantial environmental costs, making recultivating currently unused farmland an interesting alternative. The collapse of the Soviet Union in 1991 led to widespread abandonment of agricultural lands, but the extent and spatial patterns of abandonment are unclear. We quantified the extent of abandoned farmland, both croplands and pastures, across the region using MODIS NDVI satellite image time series from 2004 to 2006 and support vector machine classifications. Abandoned farmland was widespread, totaling 52.5 Mha, particularly in temperate European Russia (32 Mha), northern and western Ukraine, and Belarus. Differences in abandonment rates among countries were striking, suggesting that institutional and socio-economic factors were more important in determining the amount of abandonment than biophysical conditions. Indeed, much abandoned farmland occurred in areas without major constraints for agriculture. Our map provides a basis for assessing the potential of Central and Eastern Europe’s abandoned agricultural lands to contribute to food or bioenergy production, or carbon storage, as well as the environmental trade-offs and social constraints of recultivation.

  13. Decontamination of abandoned sites. An introduction into the problems of land decontamination

    Starting from a brief overview of the history of origin of soil and ground water pollution in Berlin and its surroundings by gas, chemical, and petroleum works, old landfills, manufactories of arms and ammunition as well as gasoline depots or sites of gasoline depots, the brochure describes the legal situation and procedure (list of 'intervention' values) and goes on to outline the situation regarding the ground under Berlin, existing pollutants, and methods for dealing with land contamination. In five abandoned sites (waste oil refinery, copper refinery, waste solvent treatment plant, asphalt factory and drugs factory), different methods for eliminating soil and ground water contamination were used. Their efficacy is assessed on the basis of their soil and pollutant-specific suitability; the decontamination achieved is indicated. (BBR)

  17. Exploring the Dynamic Mechanisms of Farmland Abandonment Based on a Spatially Explicit Economic Model for Environmental Sustainability: A Case Study in Jiangxi Province, China

    Hualin Xie

    2014-03-01

    Full Text Available Farmland abandonment has important impacts on biodiversity and ecosystem recovery, as well as food security and rural sustainable development. Due to rapid urbanization and industrialization, farmland abandonment has become an increasingly important problem in many countries, particularly in China. To promote sustainable land-use management and environmental sustainability, it is important to understand the socioeconomic causes and spatial patterns of farmland abandonment. In this study, we explored the dynamic mechanisms of farmland abandonment in Jiangxi province of China using a spatially explicit economical model. The results show that the variables associated with the agricultural products yield are significantly correlated with farmland abandonment. The increasing opportunity cost of farming labor is the main factor in farmland abandonment in conjunction with a rural labor shortage due to rural-to-urban population migration and regional industrialization. Farmlands are more likely to be abandoned in areas located far from the villages and towns due to higher transportation costs. Additionally, farmers with more land but lower net income are more likely to abandon poor-quality farmland. Our results support the hypothesis that farmland abandonment takes place in locations in which the costs of cultivation are high and the potential crop yield is low. In addition, our study also demonstrates that a spatially explicit economic model is necessary to distinguish between the main driving forces of farmland abandonment. Policy implications are also provided for potential future policy decisions.

  6. Development of database on circular abandoned channel in Japan

    To develop a method for estimating late Quaternary uplift rates of inland mountainous terrains where fluvial terraces are poorly developed, we focused on 'circular abandoned channels', formed by meander cut-offs or river capture of an incised meandering river. We studied about 1,000 circular abandoned channels distributed throughout the Islands of Japan, and developed GIS database on circular abandoned channel in Japan. This database contains formation process, relative heights, degree of dissection and bedrocks of circular abandoned channels. Circular abandoned channels are distributed in inland mountainous terrains, where late Quaternary uplift rates are unknown, and indicate different relative heights along the same river. Relative heights tend to correlate with degree of dissection of the circular abandoned channels, which may indicate that degree of dissection correlate with ages of abandonment of circular abandoned channels. A CD-ROM is attached as an appendix. (J.P.N.)

    The practice of abandoning newborns shortly after birth has always existed. Occurring in primitive and contemporary societies, the motivations for newborn abandonment are varied and dependent upon the social norms of a specific geographic region at a given point in time. Because the desire to abandon an infant has had no support system in American society, such unwanted infants have been abandoned in a manner leading to their deaths. In response, many states have passed safe-haven legislation...

  11. Hospital Qualities Related to Return to Work from Occupational Injury after Controlling for Injury Severity as Well as Occupational Characteristics.

    Won, Jong-Uk; Seok, Hongdeok; Rhie, Jeongbae; Yoon, Jin-Ha

    2016-05-01

    We examined associations between hospital quality in the workers' compensation system and injured patients' return to work after controlling for injury severity, occupational factors, and demographic factors. Return to work data of injured workers were constructed from 2 datasets: 23,392 patients injured in 2009-2011 from the Korea Workers' Compensation & Welfare Service and return to work data from Korea Employment Information Services. After de-identifying the data, quality scores were matched for each hospital that cared for injured patients. Injury severity was measured by Abbreviated Injury Scales. Relative risk and 95% confidence interval were calculated using log binomial regression models. After adjusting for age, sex, injury severity, occupation, factory size, city, and hospital type, the relative risk (95% confidence interval) for the total score was 1.04 (1.02-1.06), 1.06 (1.04-1.09), and 1.07 (1.05-1.10) in the 2(nd), 3(rd), and 4(th) quartiles, respectively, compared to the 1(st) quartile. The RR (95% CI) in the 2(nd), 3(rd), and 4(th) quartiles was 1.05 (1.02-1.07), 1.05 (1.02-1.08), and 1.06 (1.04-1.09) for the process score; and 1.02 (1.01-1.04), 1.05 (1.03-1.07), and 1.06 (1.04-1.09) for the outcome score compared to the 1(st) quartile score, respectively. In conclusion, our study design with blinded merge methods shows that total, process, and outcome qualities are related to the return to work of injured workers after controlling for other factors.

  17. The U.S. Forest Service abandoned mine land inventory in Colorado: Background, progress, and preliminary findings

    The U.S. Forest Service (USFS) and the Colorado Geological Survey (CGS) are continuing a cooperative agreement to identify sites of environmental degradation associated with abandoned and inactive mines on Colorado's USFS administered lands. The USFS Abandoned Mine Land Inventory Project is a open-quotes discoveryclose quotes process and is a precursor to the Environmental Protection Agency's open-quotes Preliminary Assessmentclose quotes process. Identification of environmentally degraded sites may lead to a formal Preliminary Assessment. The inventory process begins in the office and involves reviewing existing mining and geologic literature, previous mine inventory work, current and historical maps, water quality information, and aerial photographs. During field investigation, each mine feature is given a unique identification number. Field geologists collect data on the physical and geographic characteristics of the mine features along with information on any water emanating from or interacting with the mine features. This information is used to assign a qualitative environmental degradation rating to the individual mine feature. Guidelines for the rating system are given to field personnel to facilitate consistency within the data set. All data collected are entered into a computer database. From a computer perspective, both location and attribute data are being collected. Therefore, the data are well suited for integration into a geographic information system (GIS) creating a geo-referenced data set. The USFS Abandoned Mine Land Inventory Project began in 1991 and is ongoing. To date, field inventories of the Arapaho, Roosevelt, Pike, and Rio Grande National Forests have been completed. Work in the San Isabel, San Juan, White River, Gunnison, Uncompahgre, and Grand Mesa National Forests is in progress. Through the 1994 field season approximately 9,667 mine features (openings, dumps, tailings, highwalls, etc.) have been inventoried

    The only constant thing in today's world is change. Change is everywhere, even in the education sector. The education system has undergone tremendous changes in the past 10 years. This includes several curriculum changes. Change always contributes to stress, which individuals in the education department are experiencing quite intensively, judging by the popular media. Stressful events may lead to ill-health and might negatively impact the workforce and the overall well-being of th...

    English abstract: Background: Physical activity and well-being in everyday life are major themes in Norway currently. More recently, attention has been given to the link between physical activity and better mental health. Alongside this have been arguments for using settings, such as the workplace, for implementing strategies to create healthier workplaces. However, research on the topic of workplace physical activity and mental health among employees has not been extensively studied, particu...

  2. The Oedipus complex revisited: Oedipus abandoned, Oedipus adopted.

    Quinodoz, D

    1999-02-01

    The author considers that the Oedipus of Sophocles' drama, who kills his biological father and marries his biological mother, is an illustration of the failure to work through the complex named after him. She draws attention to the contrast between the obscurity that surrounds the hero's adoptive parents and the notoriety of their biological counterparts arguing that the former are equally important in the universal oedipal fantasy. In her view the fact that Oedipus has two sets of parents--abandoning and adopting respectively--is significant in that the resulting dichotomisation of the parental imago enables him seemingly to avoid a conflict of ambivalence in relation to a single object. The author further contends that the plague of Thebes represents the symptomatic return of repressed or disavowed aggression. Three clinical examples reveal the parental imago's division to be an unconscious defence against oedipal anxieties and the sense of solitude vis-à-vis the intimacy of the parental couple. The working through of the Oedipus complex is stated to require the synthesis of love and hate and of the abandoning and adoptive aspects of the parents whereby the formerly sadistic superego becomes protective. The author also argues that a useful distinction can be made between splitting and dichotomisation. PMID:10216814

  3. Explosives remain preferred methods for platform abandonment

    Economics and safety concerns indicate that methods involving explosives remain the most practical and cost-effective means for abandoning oil and gas structures in the Gulf of Mexico. A decade has passed since 51 dead sea turtles, many endangered Kemp's Ridleys, washed ashore on the Texas coast shortly after explosives helped remove several offshore platforms. Although no relationship between the explosions and the dead turtles was ever established, in response to widespread public concern, the US Minerals Management Service (MMS) and National Marine Fisheries Service (NMFS) implemented regulations limiting the size and timing of explosive charges. Also, more importantly, they required that operators pay for observers to survey waters surrounding platforms scheduled for removal for 48 hr before any detonations. If observers spot sea turtles or marine mammals within the danger zone, the platform abandonment is delayed until the turtles leave or are removed. However, concern about the effects of explosives on marine life remains

  4. Recycling abandoned lead battery sites

    In the past, automobile batteries were recycled principally for their lead content. The waste generated at battery wrecking facilities consisted of spent acid, crushed casings (ebonite and plastic), and where secondary smelting was involved, matte, slag, and carbon from the smelting process. These waste products were generally disposed in an on-site in a landfill or stored in piles. If the facility shut down because further commercial operations were not financially viable, the waste piles remained to be addressed at a later date through remedial action or reclamation programs. There are many of these facilities in the US. Nationally, about 28 sites have been discovered by the US Environmental Protection Agency (EPA) under the Superfund program and are under investigation or administrative orders for remedial action. A major remediation effort is now underway at the Gould Superfund Site in Portland, Oregon, which was operated as a secondary smelting facility between 1949 and 1981. This paper describes the nature of the contamination at the Gould site and the work conducted by Canonie Environmental Services Corp. (Canonie) to develop a process which would treat the waste from battery wrecking operations and produce revenue generating recyclable products while removing the source contamination (lead) from the site. The full-scale commercial plant is now operating and is expected to achieve a throughput rate of between 200 and 250 tons per day in the coming weeks

  6. Detecting abandoned objects using interacting multiple models

    Becker, Stefan; Münch, David; Kieritz, Hilke; Hübner, Wolfgang; Arens, Michael

    2015-10-01

    In recent years, the wide use of video surveillance systems has caused an enormous increase in the amount of data that has to be stored, monitored, and processed. As a consequence, it is crucial to support human operators with automated surveillance applications. Towards this end an intelligent video analysis module for real-time alerting in case of abandoned objects in public spaces is proposed. The overall processing pipeline consists of two major parts. First, person motion is modeled using an Interacting Multiple Model (IMM) filter. The IMM filter estimates the state of a person according to a finite-state, discrete-time Markov chain. Second, the location of persons that stay at a fixed position defines a region of interest, in which a nonparametric background model with dynamic per-pixel state variables identifies abandoned objects. In case of a detected abandoned object, an alarm event is triggered. The effectiveness of the proposed system is evaluated on the PETS 2006 dataset and the i-Lids dataset, both reflecting prototypical surveillance scenarios.

  7. Approaches to providing missing transfer parameter values in the ERICA Tool – How well do they work?

    A required parameter for the ERICA Tool is the concentration ratio (CR), which is used to describe the transfer from environmental media to a range of organisms. For the original parameterisation of the ERICA Tool, 60% of these values were derived using a variety of extrapolation approaches, including the application of allometric models, the use of values for a similar organism or element with similar biogeochemical behaviour and the use of values from a different ecosystem. Although similar approaches are applied in other assessment systems, there has been little attempt to see how well these approaches perform. In this paper, CR values in the ERICA Tool derived using extrapolation approaches are compared to more recently available empirical data from the IAEA wildlife transfer database. The primary purpose of the default CR database in the ERICA Tool, and other models, is to enable the user to conduct conservative screening assessments. Conservatism was therefore introduced to the analyses by selecting the 95th percentile CR values for subsequent calculations. The extrapolation methodologies are not guaranteed to provide conservative estimates of empirical 95th percentile CRs. For the terrestrial ecosystem, the extrapolation methods provide underpredictions of empirical 95th percentiles as often as they produce overpredictions. In a few cases the underestimation of CR values, when considering all ecosystems, is substantial - by orders of magnitude - which is clearly unacceptable for a screening assessment. Thus, although extrapolation approaches will remain an essential component of screening assessments in the future, because data gaps will always be present, diligence is important in their application. Finally, by synthesizing the results from the current analyses and through other considerations, some recommendations are provided with regards to modifying the original guidance on use of extrapolation approaches in the ERICA Tool

  8. Changes in soil carbon and nitrogen following land abandonment of farmland on the Loess Plateau, China.

    Lei Deng

    Full Text Available The revegetation of abandoned farmland significantly influences soil organic C (SOC and total N (TN. However, the dynamics of both soil OC and N storage following the abandonment of farmland are not well understood. To learn more about soil C and N storages dynamics 30 years after the conversion of farmland to grassland, we measured SOC and TN content in paired grassland and farmland sites in the Zhifanggou watershed on the Loess Plateau, China. The grassland sites were established on farmland abandoned for 1, 7, 13, 20, and 30 years. Top soil OC and TN were higher in older grassland, especially in the 0-5 cm soil depths; deeper soil OC and TN was lower in younger grasslands (<20 yr, and higher in older grasslands (30 yr. Soil OC and N storage (0-100 cm was significantly lower in the younger grasslands (<20 yr, had increased in the older grasslands (30 yr, and at 30 years SOC had increased to pre-abandonment levels. For a thirty year period following abandonment the soil C/N value remained at 10. Our results indicate that soil C and TN were significantly and positively correlated, indicating that studies on the storage of soil OC and TN needs to focus on deeper soil and not be restricted to the uppermost (0-30 cm soil levels.

  11. Worker and environmental protection issues in the remediation of an abandoned source manufacturing facility.

    Hoffman, Daniel E

    2003-02-01

    The Gulf Nuclear Superfund Site located in Odessa, Texas, was an abandoned radioactive source production facility slated for cleanup as a Removal Action under the U.S. Environmental Protection Agency Region VI Superfund program. Prior to cessation of operations and abandonment of the facility in 1992, it was used for the production of radioactive sources used in the oil and gas industry and nuclear medicine applications. Pangea Group was contracted by the U.S. Army Corps of Engineers (USACE) Kansas City District to perform remediation of the site and other contaminated debris, cleaning of interior building surfaces, building demolition, and excavation/removal of contaminated soils and septic system. The project scope also included loading, containerization and transportation of low-level radioactive wastes for offsite disposal. Primary radionuclides present at the facility were 137Cs, 60Co, and 241Am. The project also included packaging and removal of radioactive sources and mixed waste consisting of radiologically contaminated lead shot and lead source containers. Included in the paper is a discussion of primary worker protection and environmental protection measures employed on the project. Worker protection issues included the control of industrial and construction safety hazards as well as control of external and internal radiation dose. Control of air emissions and contaminated wastewater were also very important, especially due to the location of the site. The site was located in an area containing both residential and commercial properties. Several residences and businesses were located immediately adjacent to the site. The project involved the participation of the USACE Kansas City District, EPA Region 6, and the Texas Bureau of Radiological Health. Field work on the project started in April 2001 and was completed approximately five months later. PMID:12564344

    2006-01-01

    Recent corporate scandals around the world have led many to single out executive stock options as one of the main culprits. More corporations are abandoning stock options and reverting to restricted stock. This paper argues that such a change is not entirely justifiable. We first provide a critical review of the pros and cons of executive stock options. We then compare option-based contracts with stock-based contracts using a simple principal-agent model with moral-hazard. In a general enviro...

  14. Reclamation of abandoned underground mines in the United Kingdom

    Since 1980, the Derelict Land Grant program has supported reclamation of abandoned mines in the United Kingdom. The stabilization of large-scale limestone mines in the West Midlands has stimulated the development of new methods of bulk infilling using waste materials as thick pastes. Colliery spoil rock paste develops strengths of 10 to 20 kPa to support roof falls and prevent crown hole collapse. Pulverized fuel ash rock paste develops strengths over 1 MPa where lateral support to pillars is required. Smaller scale mine workings in the West Midlands and elsewhere have been stabilized using conventional grouting techniques, hydraulic and pneumatic stowing, foamed-concrete infill, bulk excavation with controlled backfill, and structural support using bolts, mesh, and shotcrete

  15. Design of the DISCovery project: tailored work-oriented interventions to improve employee health, well-being, and performance-related outcomes in hospital care

    2013-02-01

    Full Text Available Abstract Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job demands, job resources, and recovery opportunities into effective workplace interventions. The aim of the DISCovery project is to develop and implement tailored work-oriented interventions to improve health, well-being, and performance of health care personnel. Methods/Design A quasi-experimental field study with a non-equivalent control group pretest-posttest design will be conducted in a top general hospital. Four existing organizational departments will provide both an intervention and a comparison group. Two types of research methods are used: (1 a longitudinal web-based survey study, and (2 a longitudinal daily diary study. After base-line measures of both methods, existing and yet to be developed interventions will be implemented within the experimental groups. Follow-up measurements will be taken one and two years after the base-line measures to analyze short-term and long-term effects of the interventions. Additionally, a process evaluation and a cost-effectiveness analysis will be carried out. Discussion The DISCovery project fulfills a strong need for theory-driven and scientifically well-performed research on job stress and performance interventions. It will provide insight into (1 how a balance between job demands, job resources, and recovery from work can be optimized, (2 the short-term and long-term effects of tailored work-oriented effects, and (3 indicators for successful or unsuccessful implementation of interventions.

    Higuchi, K. [The Society of Engineers for Mineral Springs, Tokyo (Japan)

    1997-03-31

    Problems and consideration in well drilling from the application to the completion of the well are discussed from the viewpoint of hot spring drilling industry. In the case of developing a hot spring, it is required to make an application for drilling and get permission based on the hot spring law. Inquiries must be made for `other laws` to obtain necessary permission and a written consent. Subjects which should be considered regarding the core, drilling depth, and diameter of the well are introduced. The drilling depths from 1,000m to 1,500m become common recently, and wells with more than 2,000m depths are drilled sometimes. The technology for hot spring drilling is also an important factor. Documents desirable to be attached to the contract for preventing future troubles beforehand are indicated. Among the important works during the work period, confirmation whether the work has been carried on in accordance with the documents for design and plan is necessary. Problems and consideration during finishing and hot spring water pumping tests are discussed. 5 figs., 6 tabs.

  18. Effect of biochar produced at different pyrolysis temperature on the soil respiration of abandoned mine soil

    Kim, Yong Seong; Kim, Juhee; Hwang, Wonjae; Hyun, Seunghun

    2015-04-01

    Contaminated soils near an abandoned mine site included the high acidic mine tailing have received great interest due to potential risk to human health, because leachable elements in low pH continuously release from mine site soil with ground water and precipitation event. Biochar, which is the obtained pyrolysis process of biomass, is used as a soil amendments and carbon storage. Especially, many researchers report that the biochar application to soil show increasing soil pH, CEC, adsorption capacity of various elements, as well as, enhanced microbial activity. Therefore, biochar application to contaminated soil near abandoned mine site is expected to have a positive effects on management of these site and soils through the decreased leachability of contaminants. However, effects of biochar application to these site on the soil respiration, as a common measure of soil health, are poorly understood. The objective of this study is to evaluate the effects of biochar application to abandoned mine site soil on the microbial activity with soil respiration test. Biochar was obtained from giant Miscanthus in a slow pyrolysis process (heating rate of 10° C min-1 and N2 gas flow rate of 1.2 L min-1) at the temperature of 400° C (BC4) and 700° C (BC7), respectively. All biochar samples were prepared with grinding and sieving for particle size control (150~500μm). Soil sample was collected from abandoned mine site at Korea (36° 58'N, 128° 10'E). Main contaminants of this soil were As (12.5 g kg-1), Pb (7.3 g kg-1), and Zn (1.1 g kg-1). Biochars were applied (5% by dry weight) to the soil (final mixture weight were 800g), and then moisture contents were adjusted to 100% field capacity (-0.33 bar) in the respirometer with vacuum pump. CO2 efflux of each samples was continuously assessed using continuous aeration system (air flow rate 25 cc min-1) using air cylinder during 130hr (at 20° C and darkness condition). The CO2 emitted from the samples were carried to the

  19. Detection and control of fires and heatings in shallow, abandoned coal mines

    Heatings and fires in shallow, abandoned coal mines create an environmentally undesirable hazard in the Witbank area in South Africa, as well as locations in Europe and North America. A research program was set up in South Africa to detect and control the occurrence and extent of subsurface heatings and fires. Prior to any remedial action being taken to control or extinguish a heating or fire, it is essential to evaluate underground conditions in order to determine the most effective control method. Normally, such workings cannot physically be entered due to poor ground conditions and the presence of heat and toxic gases. Two novel detection methods have been developed by the Chamber of Mines Research Organization (COMRO) for the purpose of identifying the nature and extent of such heatings remotely, via surface boreholes. Temperature monitoring allows for the detection of heating intensity and location. To determine areas of uncontrolled air infiltration into the workings, tracer gas technology is used. In addition, a method for controlling a fire which has been successfully used in South Africa is described

  1. A 12-year cavern abandonment test

    Brouard B.

    2010-06-01

    Full Text Available In 1997-1998, an abandonment test was performed in a 950-m deep, 8000-m3 salt cavern operated by GDF SUEZ at Etrez, France. In this relatively small brine-filled cavern, which had been kept idle for 15 years before the test, thermal equilibrium was reached. A special system was designed to monitor leaks, which proved to be exceedingly small. In these conditions, brine permeation and cavern creep closure are the only factors to play significant roles in pressure evolution. This test strongly suggested that obtaining an equilibrium pressure such that the effects of these two factors were exactly equal would be reached in the long term. Four years later, pressure monitoring in the closed cavern resumed. Pressure evolution during the 2002-2009 period confirmed that cavern brine pressure will remain constant and significantly smaller than geostatic pressure in the long term, precluding any risk of fracturing and brine seepage to the overburden layers.

    2013-04-01

    Full Text Available Plants growing on the abandoned Portuguese mines, highly contaminated with W, Sn, As, Cd, Cu, Zn and Pb, have been studied for their biogeochemical indication/prospecting and mine restoration potential. The results of analysis show that the species best suited for biogeochemical indicating are: aerial tissues of Halimium umbellatum (L. Spach, for As and W; leaves of Erica arborea L. for Bi, Sn, W and mostly Pb; stems of Erica arborea L. for Pb; needles of Pinus pinaster Aiton and aerial tissues of Pteridium aquilinum (L. Kuhn for W; and leaves of Quercus faginea Lam. for Sn. The aquatic plant studied (Ranunculus peltatus Schrank can be used to decrease the heavy metals, and arsenic amounts into the aquatic environment affected by acid mine drainages.

    Full Text Available During the transition period, in Romania, the dimension of school abandon had risen. The main goals of the study are: to estimate the school abandon rate by each educational level in Romania, to identify the factors which affect school abandon on urban and rural areas and at development regions level; to analyze the causes of earlier school abandon. In the same time, the analysis had also followed the temporal component, by including in the database the last decade statistical information. The school abandon was measured as the difference between the numbers of pupils/students found at the end of the school year and the same category enrolled at the beginning of the same year.

  4. Abandoned Rice Fields Make Streams Go Dry in Upland Landscapes

    Jayawickreme, D.

    2015-12-01

    In South Asia, new economic realities are driving many rural rice farmers out of agriculture. With increasing neglect, abandonment, and rising conversions of centuries old rice fields into other uses, ecological and environmental consequences of these transitions are becoming progressively clear. Field observations in Sri Lanka's central highlands suggest that small shifts in rice to non-rice land uses in headwater watersheds can have a domino effect on the productivity and viability of rice fields and other ecological systems downstream by inflicting groundwater recharge reductions, lowering groundwater yields, and causing other hydrological changes. Preliminary analysis shows that although rice itself is a very water intensive crop, the presence of rain-fed upland rice-fields is hugely beneficial to the watersheds they reside. In particular, water benefits of rice appear to be derived from ponded conditions (3-5 inches of standing water) in which rice is grown, and the contribution rice fields makes to enhance water retention and storage capacity of their watersheds during the monsoon season that coincide with the cropping season. In the absence of well managed rice-fields, hilly upland landscapes produce more runoff and retain little rainwater during the wet season. Furthermore, after centuries of intensive use, much of South Asia's rice fields are nutrient poor and minimally productive without fertilizer applications and other interventions. Consequently, when abandoned, soil erosion and other impacts that affect aquatic ecosystems and watershed health also emerge. Despite these multiple concerns however, little research is currently done to better understand the environmental significance of rice cultivations that are a dominant land-use in many South Asian landscapes. The aim of this presentation is to stir interest among the scientific community to engage more broadly in rice, water, and environmental change research in the face of new economic realities in

    1999-07-01

    The aim of this research on 143 workers of the ENEA area in Bologna, has been to survey the degree of well-being perceived and expressed by these workers with respect to different factors of the work environment. This study follows some training/information seminars on environment, health and safety organized in ENEA by Occupational Medicine Group to comply with Leg. Decr. 626/94. In a multidisciplinary approach the health idea has been interpreted not as lack of illness but as pursuit and preservation of the well-being in the work environment. For this purpose, also the involvement and participation of the workers seem to be very useful for subjective reports about individual task, equipment, interfaces, workplace and work organization. In this research, we have adopted an ergonomic checklist based on guiding principles to be applied to the design of optimal working conditions with regard to human well-being, safety and health (see UNI ENV 26385, 1991). Data processing and analysis have requested occupational medicine, ergonomics and statistics competencies. [Italian] La ricerca condotta su un campione ENEA di 143 dipendenti dell'area bolognese ha inteso verificare il grado di benessere percepito ed espresso dai lavoratori in rapporto alle diverse variabili presenti nel contesto lavorativo. Tale indagine e' stata preceduta da specifici seminari di formazione/informazione su ambiente, salute e sicurezza, organizzati a cura della Medicina del Lavoro di Bologna presso le sedi ENEA, a seguito delle disposizioni contenute nel D.Lvo. 626/94. In un'ottica multidisciplinare, il concetto di salute e' stato interpretato non tanto come assenza di malattia quanto come ricerca e mantenimento del benessere lavorativo e, per raggiungere questo scopo, sembra essere molto utile anche il diretto coinvolgimento e la partecipazione dei lavoratori per valutazioni soggettive sulle mansioni assegnate, le attrezzature, le interfacce, la postazione di lavoro e l

    the S-sequence (18.1±10.4%) than in the SW-sequence (6.7±2.7%); consequently. The pH of the topsoil was higher in the S-sequence, and correlated significantly negatively with the age of abandonment in both sequences (r=‑0.893; p=0.01 in S, and r=‑0.739; p=0.05 in SW). TOC stocks of the top 6 cm soil layers were higher in the S-sequence (1.82±0.71 kg m-2) than in the SW-sequence (0.95 ± 0.49 kg m-2), and correlated significantly positively with the duration of self-restoration. When calculated for the whole profile, TOC stocks were similar in both S- and SW-sequences (S: 8.21±3.31 kg m-2; SW: 8.24±6.01 kg m-2). The TOC accumulation rates of the top 6 cm soil layers exhibited 18.9±10.0 g C m-2y-1 in the S and 7.0±4.2 g C m-2y-1 in the SW-sequence. Sites with the same age of abandonment developed to different vegetation and had different soil features in both chronosequences, indicating that duration of self-restoration is only one of the directive factors in soil development and carbon sequestration processes after abandonment of viticulture on Tokaj Nagy-Hill, which was significantly affected by lithology, slope steepness and exposition as well.

    This study was performed to find the way that is alternative utilization of the drift that had been abandoned by coal industry promotion. To determine whether abandoned drift would be maintained without supports or not, the safety inspection that consists of drift survey, laboratory tests, rock mass classification and numerical analysis was performed. According to the result, there were discontinuity sets those had unfavorable orientation to the drift and rock mass around the drift had generally poor condition. So, it would be much difficult that abandoned drift is maintained without supports. (author). 15 refs., 8 tabs., 7 figs.

    Some results on long-term dynamics of migration movability of ChNPP release radionuclides in soils of abandoned areas have been analyzed and summarized. Role of physical-chemical forms of fallout as well as landscape geochemical characteristics of the territory has been estimated. Dynamics of 90Sr migration in soils of fuel tracks of ChNPP fallout is in the main difference in comparison with 137Cs.

  10. Lifetime of a Natural Gas Storage Well Assessment of Well-Field Maintenance Cost

    Gaz de France has been operating underground gas storage wells since more than 50 years. These wells have been drilled with the current available technologies in oil and gas industry. These technologies had improved a lot in the last decades (slurry compositions, drilling and cementing techniques, etc.) and the lifetime of a well therefore has to be estimated with reference to the techniques in use at the date it was built. These uncertainties and the inaccurate data of the oldest wells (drilling logs and casings specifications) led GDF to investigate the wells lifetime. Two approaches are presented here: - assessing a theoretical lifetime of a well; - calculating the average lifetime of each well using essentially corrosion scenarios and kinetics. Combining the two different approaches, one can better assess well aging and remaining well lifetime in order to schedule the best action (work-over, abandonment) at the proper time. A better knowledge of well's lifetime enables good control of underground storage operational expenditures (OPEX). (author)

  17. THE REMEDIATION OF ABANDONED IRON ORE MINE SUBSIDENCE IN ROCKAWAY TOWNSHIP, NEW JERSEY

    Gary Gartenberg, P.E., P.P.

    1999-10-01

    This report represents the fourth Semi-Annual Technical Progress Report issued in connection with the subsidence remediation projects undertaken by Rockaway Township in Morris County, New Jersey. This report provides a summary of the major project work accomplished during this reporting period and contemplated for the subsequent reporting period. This report is issued as part of the project reporting provisions set forth in the Cooperators Agreement between the United States Government--Department of Energy, and Rockaway Township. The purpose of the Cooperators Agreement is for the Department of Energy to provide technical and financial assistance in a coordinated effort with Rockaway Township to develop and implement a multi-phased plan to remediate ground stability problems associated with abandoned mining activity. Primarily during the 1800's, extensive iron ore mining and prospecting was undertaken in Rockaway Township, part of the Dover District Mining region in Morris County. The abandoned mining activity has resulted in public safety hazards associated with ground collapse and surface subsidence features evolving in both developed and undeveloped areas within Rockaway Township. During this reporting period the Engineering Design for remediation of the surface safety hazards associated with the White Meadow Mine was completed. Construction Plans and Technical Specifications were completed and competitive bids were solicited by the Township for completion of the work. The electrical resistivity survey analysis and report was completed for the Green Pond Mines site at the Township Compost Storage Facility. The geophysical survey results confirmed evidence of abandoned mining activity at the Green Pond Mine site which was previously identified. During this reporting period, the time frame of the Cooperative Agreement between the Township and the Department of Energy was extended. An additional site of subsidence with in the Township related to abandoned

  18. Development of a Special Application Coiled Tubing Applied Plug for Geothermal Well Casing Remediation

    STALLER,GEORGE E.; KNUDSEN,STEVEN D.; SATTLER,ALLAN R.

    1999-10-01

    Casing deformation in producing geothermal wells is a common problem in many geothermal fields, mainly due to the active geologic formations where these wells are typically located. Repairs to deformed well casings are necessary to keep the wells in production and to occasionally enter a well for approved plugging and abandonment procedures. The costly alternative to casing remediation is to drill a new well to maintain production and/or drill a well to intersect the old well casing below the deformation for abandonment purposes. The U.S. Department of Energy and the Geothermal Drilling Organization sponsored research and development work at Sandia National Laboratories in an effort to reduce these casing remediation expenditures. Sandia, in cooperation with Halliburton Energy Services, developed a low cost, bridge-plug-type, packer for use in casing remediation work in geothermal well environments. This report documents the development and testing of this commercially available petal-basket packer called the Special Application Coiled Tubing Applied Plug (SACTAP).

  19. Stripper, shut-in and orphan wells in joint operations

    Low productivity wells, stripper wells, can be an excellent source of income to independent operators or small companies, but a serious financial burden for larger companies. Shut-in wells, for most companies, are either waiting on a market and production facilities, or represent deferred abandonment liabilities. Orphan wells also reflect financial distress. The firm, Cord Oil and Gas Management Ltd., was formed in 1986 to specifically assist oil and gas companies, sophisticated investors and financial institutions with the management, enhancement and disposition of non-core or low productivity assets. This type of production, depending on the number of wells and cumulative production, can be the life blood of a small organization or a serious drain on the administrative personnel and financial resources of larger organizations. Philosophically, industry and/or government needs to manage the eventuality of abandonments by establishing financial criteria. Some suggestions for industry include: (1) establish provisions within joint operating agreements to set aside an abandonment and environmental cleanup fund; (2) minimize the inventory of abandonment candidates by an ongoing program of reclamation; (3) offset abandonment costs with salvage value of tangible equipment under AFE approval; and (4) voluntarily restrict transfer abandonment liabilities with producing assets on a selective basis. Some suggestions for governments include: (1) fund the orphan well by a deposit for every well drilled; (2) restrict the transfer of liabilities for abandoned and inactive wells by ensuring that the transferee is financially capable; and (3) access the chain of title to ensure non-operators remain responsible for the proportionate shares of abandonment and cleanup costs

  20. Feasibility analysis of using abandoned salt caverns for large-scale underground energy storage in China

    Highlights: • A method is proposed for the evaluation of using an abandoned salt cavern for energy (natural gas) storage. • A feasibility analysis is given of China’s first UGS (Underground Gas Storage) facility using an abandoned salt cavern. • Numerical modeling has been used to investigate mechanical safety of a gas pressurized cavern. • Chinese abandoned salt caverns show good feasibility of being converted to UGSs. • China’s bedded rock salt can meet the requirements for UGS. - Abstract: Rock salt in China is primarily bedded salt, usually composed of many thin salt layers and interlayers (e.g. anhydrite, mudstone, and glauberite). Thus, the feasibility analysis of abandoned salt caverns located in salt beds to be used as Underground Gas Storage (UGS) facilities is full of challenges. In this paper, we introduce the feasibility analysis of China’s first salt cavern gas storage facility using an abandoned salt cavern. The cavern is located in Jintan city, Jiangsu province, China. The mechanical properties and permeability of the bedded salts are obtained by experiments. Based on the results of the analyses, it appears to be quite feasible to convert the abandoned salt caverns of Jintan city to UGS facilities. The stability of the cavern is evaluated by the 3D geomechanical numerical simulations, and the operating parameters are proposed accordingly. Results indicate that the maximum volume shrinkage of the cavern is less than 25% and the maximum deformations are less than 2% of the caverns’ maximum diameters after operating for 20 years. It is recommended that the weighted average internal gas pressure be maintained as 11 MPa to control the extent of the plastic zones to a safe level. Safety factors decrease with operating time, especially those of the interface between rock salt and mudstone layers decrease significantly. Effective strain is generally greater than 2%, and locally is greater than 3% after operating 20 years. The maximum

    Matthews, Richard J. [PIMS of London Ltd, London, (United Kingdom); Galvez Reyes, Marco Antonio [PEMEX Refinacion, Veracruz, (Mexico)

    2010-07-01

    The decommissioning and abandonment of platforms and pipelines are big challenges for the pipeline industry. This paper presents a review of the decommissioning and abandonment processes based on a study case, the Rabon Grande pipeline system. First, the applicable international codes, standards and regulations associated with the decommissioning of pipelines are discussed. Next, this paper presents a review of the decommissioning and abandonment options and considerations available for the study case. The Rabon Grande pipeline system, which was shut down and isolated in 1990 pending decommissioning, is used as an example of applying decommissioning and abandonment best practice and establishing a realistic scope of work. A decommissioning plan is developed in light of these previous studies, followed by an environmental impact assessment. It is found that contrary to what was done in the case of the Rabon Grande pipeline, when a pipeline is to be shutdown, the best practice methodology is to temporally or fully decommission the system as soon as possible.

    2014-01-01

    Full Text Available Abandoning a heritage building is not a new phenomenon. In George Town, Penang specifically, there are many dilapidated heritage buildings that can be seen. These undeniable eye sores affect Penang’s designation as a UNESCO World Heritage Site. This research aims to identify and assess the issues related to the dangerous hazards of abandoned buildings as well as problems involved in restoring these historical structures in order to determine how severe the current situation is. This study was also carried out to better understand the reasons why owners decide to leave heritage buildings unoccupied to the point that they became unsafe to inhabit. A total of six case studies were carried out with data collection focusing on the historical background of each site, clarification of the causes of neglect to each heritage building and plans made by respective owners towards the future of their properties. The majority of relevant information was gathered through semi-structured interviews.

  3. Groundwater flow modelling of an abandoned partially open repository

    Bockgaard, Niclas (Golder Associates AB (Sweden))

    2010-12-15

    As a part of the license application, according to the nuclear activities act, for a final repository for spent nuclear fuel at Forsmark, the Swedish Nuclear Fuel and Waste Management Company (SKB) has undertaken a series of groundwater flow modelling studies. These represent time periods with different hydraulic conditions and the simulations carried out contribute to the overall evaluation of the repository design and long-term radiological safety. The modelling study presented here serves as an input for analyses of so-called future human actions that may affect the repository. The objective of the work was to investigate the hydraulic influence of an abandoned partially open repository. The intention was to illustrate a pessimistic scenario of the effect of open tunnels in comparison to the reference closure of the repository. The effects of open tunnels were studied for two situations with different boundary conditions: A 'temperate' case with present-day boundary conditions and a generic future 'glacial' case with an ice sheet covering the repository. The results were summarized in the form of analyses of flow in and out from open tunnels, the effect on hydraulic head and flow in the surrounding rock volume, and transport performance measures of flow paths from the repository to surface

  5. Abandoned coal mine refuse areas: their reclamation and use

    Zellmer, S. D.; Carter, R. P.

    1977-01-01

    There are over 4,000 abandoned deep coal mine refuse areas in Illinois ranging in size from a few acres to as large as 160 acres. These sites produce quantities of pollutants which affect the environment, have no real land value, and are a scar on the landscape. The Staunton 1 Site Reclamation Demonstration Project addressess these problems. It also is developing and evaluating new cost-effective methods for reclaiming refuse areas of this type. The program involved determining the final land use for the site, development of detailed engineering plans and specifications for the reclamation effort, a prereclamation environmental inventory, and implementation. Post-construction evaluation is now in process to determine the effectiveness of the reclamation effort. Detailed investigations are being conducted to determine surface water quality improvement, the amount of suitable surface cover and amendments required for revegetation, and field evaluation of candidate vegetation species for revegetation. Other research is examining soil microbial populations, soil fauna reactions, and changes in surface material characteristics at the reclamation site. Surveys are being conducted on groundwater quality, effects on the aquatic ecosystem, and wildlife use of the area. An economic evaluation is underway to determine the cost effectiveness of the total effort and of individual reclamation procedures. Preliminary results from the first year's environmental evaluation of various method tested will be described in detail. An economic assessment, including cost effectiveness, of the first year's work is given.

  7. The impact of night work on subjective reports of well-being: an exploratory study of health care workers from five nations

    Donald I Tepas

    2004-12-01

    Full Text Available OBJECTIVE: To carry out a survey data collection from health care workers in Brazil, Croatia, Poland, Ukraine and the USA with two primary goals: (1 to provide information about which aspects of well-being are most likely to need attention when shiftwork management solutions are being developed, and (2 to explore whether nations are likely to differ with respect to the impacts of night work on the well-being of workers involved in health care work. METHODS: The respondents from each nation were sorted into night worker and non-night worker groups. Worker perceptions of being physically tired, mentally tired, and tense at the end of the workday were examined. Subjective reports of perceived felt age were also studied. For each of these four dependent variables, an ANCOVA analysis was carried out. Hours worked per week, stability of weekly work schedule, and chronological age were the covariates for these analyses. RESULTS: The results clearly support the general proposal that nations differ significantly in worker perceptions of well-being. In addition, perceptions of physical and mental tiredness at the end of the workday were higher for night workers. For the perception of being physically tired at the end of a workday, the manner and degree to which the night shift impacts the workers varies by nation. CONCLUSIONS: Additional research is needed to determine if the nation and work schedule differences observed are related to differences in job tasks, work schedule structure, off-the-job variables, and/or other worker demographic variables.OBJETIVO: Coletar dados de pesquisa de profissionais da saúde no Brasil, Croácia, Polônia, Ucrânia e Estados Unidos com duas metas principais: (1 proporcionar informações quanto a aspectos do bem-estar que mais provavelmente precisam de atenção durante a elaboração de soluções administrativas para os turnos de trabalho e (2 examinar a existência de possíveis diferenças entre os países quanto ao

  9. Reclaiming abandoned mining sites: Reurbanization concepts and examples

    The Ruhr District in Germany, one of the oldest and largest hard coal mining regions in Europe, has been in a process of constant change over the last 40 years. Since the end of the World War II, the coal industry has been declining. There have been a number of successful attempts to establish new industries in the Ruhr District. However, the initiation of new industries depends strongly on the availability of space. Since the Ruhr District is a rather populated region, the only chance to gain space is to reclaim the areas formerly used by now obsolete industries. The remediation of former mining sites in the ruhr District and the reestablishment of alternative industries have now become both a challenge for city planners and a prestigious attribute for ambitious politicians. It has become the declared goal of the German government to convert the Ruhr District into the greenest industrial region in the world. This paper discusses geotechnical techniques, as well as economical risks involved, in the recycling of abandoned mining sites. To demonstrate remediation techniques used in Germany, a recent remediation project is described and analyzed

  10. Children with well controlled epilepsy possess different spatio-temporal patterns of causal network connectivity during a visual working memory task.

    Protopapa, Foteini; Siettos, Constantinos I; Myatchin, Ivan; Lagae, Lieven

    2016-04-01

    Using spectral Granger causality (GC) we identified distinct spatio-temporal causal connectivity (CC) patterns in groups of control and epileptic children during the execution of a one-back matching visual discrimination working memory task. Differences between control and epileptic groups were determined for both GO and NOGO conditions. The analysis was performed on a set of 19-channel EEG cortical activity signals. We show that for the GO task, the highest brain activity in terms of the density of the CC networks is observed in α band for the control group while for the epileptic group the CC network seems disrupted as reflected by the small number of connections. For the NOGO task, the denser CC network was observed in θ band for the control group while widespread differences between the control and the epileptic group were located bilaterally at the left temporal-midline and parietal areas. In order to test the discriminative power of our analysis, we performed a pattern analysis approach based on fuzzy classification techniques. The performance of the classification scheme was evaluated using permutation tests. The analysis demonstrated that, on average, 87.6 % of the subjects were correctly classified in control and epileptic. Thus, our findings may provide a helpful insight on the mechanisms pertaining to the cognitive response of children with well controlled epilepsy and could potentially serve as "functional" biomarkers for early diagnosis.

  11. Proceedings of 1991-workshops of the working group on 'Development and application of facilities for low temperature irradiation as well as controlled irradiation'

    This is the proceedings of 1991-workshops of the working group on 'Development and Application of Facilities for Low Temperature Irradiation as well as Controlled Irradiation' held at the Research Reactor Institute of Kyoto University on July 25, 1991 and on February 28, 1992. In the present proceedings, it is emphasized that the study of radiation damages in various materials must be performed under carefully controlled irradiation conditions (irradiation temperature, neutron spectrum and so forth) during reactor irradiations. Especially, it is pointed out that a middle scale reactor such as KUR is suitable for the precise control of neutron spectra. Several remarkable results, which are made through experiments using the Low Temperature Irradiation Facility in KUR (KUR-LTL), are reported. Also, possible advanced research programs are discussed including the worldwide topics on the radiation damages in metals, semi-conductors and also insulators. Further, the present status of KUR-LTL is reported and the advanced plan of the facility is proposed. (author)

  12. Long-Term Forest Dynamics and Land-Use Abandonment in the Mediterranean Mountains, Corsica, France

    Almudena San Roman Sanz

    2013-06-01

    Full Text Available Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents from 1774, 1913, 1975, and 2000, and human population history, 1770 to present day, to describe landscape patterns following land-use abandonment. This research showed that dramatic changes in landscape at the two study areas were caused by the suspension of human influence and the interruption of traditional farming practices. Over the study period, both study sites showed significant reforestation of shrubland and cultivated areas marked by the presence of Quercus ilex forests (+3.40% yr-1 between 1975 and 2000 and by Pinus pinaster (+3.00% yr-1 between 1975 and 2000 at one study site that had experienced heavy rural exodus. At the same time, areas containing chestnut forests decreased by 50% between 1774 and 2000 (-0.09% yr-1 between 1774 and 1975 and -1.42% yr-1 between 1975 and 2000. Shrubland expansion remained limited at both study sites. Our study highlights the value of small-scale approaches for understanding the ecological consequences of land-use abandonment and present and future land-management decisions. Discussion concludes on the importance of working with long-term series for studies on resilience in social-ecological systems and on the consequences in terms of provision of

  13. Abandoned pastoral settlements provide concentrations of resources for savanna birds

    Söderström, Bo; Reid, Robin S.

    2010-03-01

    Knowledge is poor of how fertilization affects birds in grasslands. We investigated the impact on birds of abandoned pastoral settlements that historically received very high levels of livestock dung. A total of 28 abandoned settlements and 74 landscape controls - in Koyake Group Ranch and Maasai Mara National Reserve in Kenya - were surveyed for birds during the wet and/or dry season. Our results showed that bird species richness and total abundance increased within 200 m of abandoned pastoral settlements, particularly during the dry season when foraging resources on the savanna are limited. The high concentrations of nutrients inside abandoned settlements favoured the abundance of Diptera and Coleoptera, as shown by invertebrate surveys performed during the dry season on a subset of 32 sites. Both total numbers and dry biomass of these two invertebrate orders were higher on abandoned settlements in comparison with the surrounding landscape. We conclude that higher fertilization levels cause a temporal and spatial redistribution of birds on the savanna. Livestock fertilization and bird abundance are probably linked through an increase in abundance of invertebrate food upon which birds feed in an opportunistic fashion.

    The practice of social work at school existed in the Republic of Slovenia in the past (the period of the SFRY). This paper presents the findings arising from that period, the reasons for abandoning that practice (the problems of management and the achieved educational level of the social workers at that time), as well as the theoretical assumptions forming the basis for reconsidering the possibility of its reintroduction both to primary and secondary schools. This paper presents the different...

  15. Investigation of abandoned surface settling ponds

    One of the problems that may appear during the ground reclamation of surface settling ponds of underground mines is enhanced radon exhalation from bottom sediments. This problem becomes more important when the concentration of radium isotopes in sediments is enhanced due to the discharge of radium-bearing waters into the pond. For investigations, special radon accumulation chambers have been designed and constructed. The concentration of radon in these chambers can be measured with the application of Lucas cells or activated charcoal detectors. In the latter method, radon is extracted from charcoal into a liquid scintillator and the sample is measured in a liquid scintillation spectrometer. Therefore the lower limit of detection (LLD) of the second method is as low as 0.1 mBq·m-2s-1, while the LLD for Lucas cells is 1.5 mBq·m-2s-1. The above-mentioned methods for the measurement of radon exhalation have been applied to investigations of a surface settling pond of one Polish coal mine, abandoned and emptied at the beginning of 2002. An agreement between the mine management and the local authority was to make the ground reclamation of the pond. A thick layer of sediments with an enhanced concentration of radium isotopes covers the bottom of the pond. The maximum concentration of radium isotopes in these sediments is as high as 2000 Bq/kg for 226Ra and up to 4000 Bq/kg for 228Ra. Two years after the complete release of brines from the pond, bottom sediments are still soaked with water. Therefore, measurements of radon in soil gas were not possible. On the other hand, in some parts of the pond investigations of radon exhalation coefficient were done. The preliminary results of measurements, conducted in 2002, showed that radon exhalation rates in specific parts of the pond were higher than the highest values of radon exhalation from the ground in the Upper Silesia region. Values of exhalation coefficient up to 200 mBq·m-2s-1 were found. It must be pointed out that

  17. Optimization of stimulation and cleaning works with coiled tubing equipments in low productivity wells of the Zuata Field, Junin Block Orinoco oil belt, Venezuela

    Romero, H.; Amaya, R.; Bernard, J. St. [PDVSA (Venezuela)

    2011-07-01

    The Zuata Field in the Orinoco oil belt, Venezuela, has important recoverable reserves but faces sand production and low reservoir pressures in many cases. Thus solid removal and cleaning are necessary and increase stimulation time and cost. The aim of this paper is to present a new technique for minimizing the rig time/cost. This new scheme of completion uses a cleaning technology with CCTU WellVac SandVac to clean the filling and remove formation damage from low pressure wells. Field tests were conducted in the Zuata Field on two wells operated by PDVSA. The new methodology proved successful in stimulating low pressure reservoirs and results showed that sediments were removed without significant loss of fluids, the CAPEX/OPEX per well was reduced and profitability in low and medium production wells increased. The methodology proposed herein was shown to be a good alternative for stimulating and cleaning low productivity wells.

  19. Modeling Wood Encroachment in Abandoned Grasslands in the Eifel National Park - Model Description and Testing.

    Silvana Hudjetz

    Full Text Available The degradation of natural and semi-natural landscapes has become a matter of global concern. In Germany, semi-natural grasslands belong to the most species-rich habitat types but have suffered heavily from changes in land use. After abandonment, the course of succession at a specific site is often difficult to predict because many processes interact. In order to support decision making when managing semi-natural grasslands in the Eifel National Park, we built the WoodS-Model (Woodland Succession Model. A multimodeling approach was used to integrate vegetation dynamics in both the herbaceous and shrub/tree layer. The cover of grasses and herbs was simulated in a compartment model, whereas bushes and trees were modelled in an individual-based manner. Both models worked and interacted in a spatially explicit, raster-based landscape. We present here the model description, parameterization and testing. We show highly detailed projections of the succession of a semi-natural grassland including the influence of initial vegetation composition, neighborhood interactions and ungulate browsing. We carefully weighted the single processes against each other and their relevance for landscape development under different scenarios, while explicitly considering specific site conditions. Model evaluation revealed that the model is able to emulate successional patterns as observed in the field as well as plausible results for different population densities of red deer. Important neighborhood interactions such as seed dispersal, the protection of seedlings from browsing ungulates by thorny bushes, and the inhibition of wood encroachment by the herbaceous layer, have been successfully reproduced. Therefore, not only a detailed model but also detailed initialization turned out to be important for spatially explicit projections of a given site. The advantage of the WoodS-Model is that it integrates these many mutually interacting processes of succession.

  1. In-situ bioremediation via horizontal wells

    This project is designed to demonstrate in situ bioremediation of groundwater and sediment contaminated with chlorinated solvents. Indigenous microorganisms were stimulated to degrade TCE, PCE and their daughter products in situ by addition of nutrients to the contaminated zone. In situ biodegradation is a highly attractive technology for remediation because contaminants are destroyed, not simply moved to another location or immobilized, thus decreasing costs, risks, and time, while increasing efficiency and public and regulatory acceptability. Bioremediation has been found to be among the least costly technologies in applications where it will work (Radian 1989). Subsurface soils and water adjacent to an abandoned process sewer line at the SRS have been found to have elevated levels of TCE (Marine and Bledsoe 1984). This area of subsurface and groundwater contamination is the focus of a current integrated demonstration of new remediation technologies utilizing horizontal wells. Bioremediation has the potential to enhance the performance of in situ air stripping as well as offering stand-alone remediation of this and other contaminated sites (Looney et al. 1991). Horizontal wells could also be used to enhance the recovery of groundwater contaminants for bioreactor conversions from deep or inaccessible areas (e.g., under buildings) and to enhance the distribution of nutrient or microbe additions in an in situ bioremediation

  2. Patch dynamics and the timing of colonization-abandonment events by male Kirtland’s Warblers in an early succession habitat

    Habitat colonization and abandonment affects the distribution of a species in space and time, ultimately influencing the duration of time habitat is used and the total area of habitat occupied in any given year. Both aspects have important implications to long-term conservation planning. The importance of patch isolation and area to colonization–extinction events is well studied, but little information exists on how changing regional landscape structure and population dynamics influences the variability in the timing of patch colonization and abandonment events. We used 26 years of Kirtland’s Warbler (Dendroica kirtlandii) population data taken during a habitat restoration program (1979–2004) across its historical breeding range to examine the influence of patch attributes and temporal large-scale processes, specifically the rate of habitat turnover and fraction of occupied patches, on the year-to-year timing of patch colonization and abandonment since patch origin. We found the timing of patch colonization and abandonment was influenced by patch and large-scale regional factors. In this system, larger patches were typically colonized earlier (i.e., at a younger age) and abandoned later than smaller patches. Isolated patches (i.e., patches farther from another occupied patch) were generally colonized later and abandoned earlier. Patch habitat type affected colonization and abandonment; colonization occurred at similar patch ages between plantation and wildfire areas (9 and 8.5 years, respectively), but plantations were abandoned at earlier ages (13.9 years) than wildfire areas (16.4 years) resulting in shorter use. As the fraction of occupied patches increased, patches were colonized and abandoned at earlier ages. Patches were abandoned at older ages when the influx of new habitat patches was at low and high rates. Our results provide empirical support for the temporal influence of patch dynamics (i.e., patch destruction, creation, and succession) on

    Commercial and centralized drilling-fluid disposal (CCDD) sites receive a portion of spent drilling fluids for disposal from oil and gas exploration and production (E&P) operations. Many older and some abandoned sites may have operated under less stringent regulations than are currently enforced. This study provides a census, compilation, and summary of information on active, inactive, and abandoned CCDD sites in Louisiana, New Mexico, Oklahoma, and Texas, intended as a basis for supporting State-funded assessment and remediation of abandoned sites. Closure of abandoned CCDD sites is within the jurisdiction of State regulatory agencies. Sources of data used in this study on abandoned CCDD sites mainly are permit files at State regulatory agencies. Active and inactive sites were included because data on abandoned sites are sparse. Onsite reserve pits at individual wells for disposal of spent drilling fluid are not part of this study. Of 287 CCDD sites in the four States for which we compiled data, 34 had been abandoned whereas 54 were active and 199 were inactive as of January 2002. Most were disposal-pit facilities; five percent were land treatment facilities. A typical disposal-pit facility has fewer than 3 disposal pits or cells, which have a median size of approximately 2 acres each. Data from well-documented sites may be used to predict some conditions at abandoned sites; older abandoned sites might have outlier concentrations for some metal and organic constituents. Groundwater at a significant number of sites had an average chloride concentration that exceeded nonactionable secondary drinking water standard of 250 mg/L, or a total dissolved solids content of >10,000 mg/L, the limiting definition for underground sources of drinking water source, or both. Background data were lacking, however, so we did not determine whether these concentrations in groundwater reflected site operations. Site remediation has not been found necessary to date for most abandoned

  9. Are plants growing at abandoned mine sites suitable for phytoremediation of contaminated soils?

    Bini, Claudio; Buffa, Gabriella; Fontana, Silvia; Wahsha, Mohammad

    2013-04-01

    Plants growing on abandoned mine sites are of particular interest in the perspective to remediate contaminated soils by phytoremediation, a low cost and environmental friendly technique which uses metal-accumulator plants to clean up moderately contaminated areas. The choice of plants is a crucial aspect for the practical use of this technique, given the ability to accumulate metals in their tissues, being genetically tolerant to high metal concentrations. Up today, more than 400 native plants that hyperaccumulate metals are reported, Brassicaceae being the family with the largest number of hyperaccumulator species. For example, Alyssum bertoloni is well known as Ni accumulator, as well as Thlaspi caerulescens for Zn and Brassica napus for Pb. However, metal hyperaccumulation is not a common phenomenon in terrestrial higher plants, and many of the European hyperaccumulator plants are of small biomass, and have a slow growth rate. Therefore, there is an urgent need for surveying and screening of plants with ability to accumulate metals in their tissues and a relatively high biomass. In recent years, a survey of soils and plants growing on contaminated areas at several abandoned sulphide mines in Italy was carried out by working groups of the Universities of Florence, Siena, Cagliari, Bologna, Udine and Venice, in order to evaluate the ability of these plants to colonize mine waste and to accumulate metals, in the perspective of an ecological restoration of contaminated sites. We investigated the heavy metal concentration of the waste material, and the soils developed from, in order to determine the extent of heavy metal dispersion, and the uptake by plants, and deserved attention to wild plants growing at that sites, to find out new metal-tolerant species to utilize in soil remediation. Current results of these investigations, with particular emphasis on the Tuscan areas, are reported here. All the studied profiles are strongly enriched in metals; their

  10. Geophysical void detection at the site of an abandoned limestone quarry and underground mine in southwestern Pennsylvania

    Locating underground voids, tunnels, and buried collapse structures continues to present a difficult problem for engineering geoscientists charged with this responsibility for a multitude of different studies. Solutions used and tested for void detection have run the gamut of surface geophysical and remote sensing techniques, to invasive trenching and drilling on closely-spaced centers. No where is the problem of locating underground voids more ubiquitous than in abandoned mined lands, and the U.S. Bureau of Mines continues to investigate this problem for areas overlying abandoned coal, metal, and nonmetal mines. Because of the great diversity of resources mined, the problem of void detection is compounded by the myriad of geologic conditions which exist for abandoned mined lands. At a control study site in southwestern Pennsylvania at the Bureau's Lake Lynn Laboratory, surface geophysical techniques, including seismic and other methods, were tested as a means to detect underground mine voids in the rather simple geologic environment of flat-lying sedimentary strata. The study site is underlain by an abandoned underground limestone mine developed in the Wymps Gap Limestone member of the Mississippian Mauch Chunk Formation. Portals or entrances into the mine, lead to drifts or tunnels driven into the limestone; these entries provided access to the limestone where it was extracted by the room-and-pillar method. The workings lie less than 300 ft from the surface, and survey lines or grids were positioned over the tunnels, the room-and-pillar zones, and the areas not mined. Results from these geophysical investigations are compared and contrasted. The application of this control study to abandoned mine void detection is apparent, but due to the carbonate terrain of the study site, the results may also have significance to sinkhole detection in karst topography

  11. A Difference-In-Differences Study of the Effects of a New Abandoned Building Remediation Strategy on Safety.

    Michelle C Kondo

    Full Text Available Vacant and abandoned buildings pose significant challenges to the health and safety of communities. In 2011 the City of Philadelphia began enforcing a Doors and Windows Ordinance that required property owners of abandoned buildings to install working doors and windows in all structural openings or face significant fines. We tested the effects of the new ordinance on the occurrence of crime surrounding abandoned buildings from January 2011 to April 2013 using a difference-in-differences approach. We used Poisson regression models to compare differences in pre- and post-treatment measures of crime for buildings that were remediated as a result of the ordinance (n = 676 or permitted for renovation (n = 241, and randomly-matched control buildings that were not remediated (n = 676 or permitted for renovation (n = 964, while also controlling for sociodemographic and other confounders measured around each building. Building remediations were significantly associated with citywide reductions in overall crimes, total assaults, gun assaults and nuisance crimes (p < 0.001. Building remediations were also significantly associated with reductions in violent gun crimes in one city section (p < 0.01. At the same time, some significant increases were seen in narcotics sales and possession and property crimes around remediated buildings (p < 0.001. Building renovation permits were significantly associated with reductions in all crime classifications across multiple city sections (p < 0.001. We found no significant spatial displacement effects. Doors and windows remediation offers a relatively low-cost method of reducing certain crimes in and around abandoned buildings. Cities with an abundance of decaying and abandoned housing stock might consider some form of this structural change to their built environments as one strategy to enhance public safety.

    Urban landscapes can be transformed by widespread abandonment from population and economic decline. Ecological assembly, sometimes referred to as “greening”, following abandonment can yield valuable ecosystem services, but also can pose a risk to public health. Abandonment can elevate zoonotic vector-borne disease risk by favoring the hyperabundance of commensal pests and pathogen vectors. Though greater biodiversity in abandoned areas can potentially dilute vector-borne pathogen transmission...

    Hope plays an important role in all individuals’ lives both today and in the future. While hope and hopelessness are important concepts and the subjects of much theorizing in psychology, theology, philosophy, political science, nursing, as well as in literature and the arts, it is absent from economics. This silence on hope is notable since hope is fundamentally at the centre of choice, especially intertemporal choice, which is at the centre of economic analysis. To place hope at the centre o...

  20. Radon exposure in abandoned metalliferous mines of South America

    Since the days of the Spanish and Portuguese conquerors, South America has been closely associated with the metalliferous ore mining. Gold, silver, tin, lead, tungsten, nickel, copper, and palladium ores have been explored over the last centuries. In addition, there has also been the development and promotion of other economic activities related to mining, as the underground mine tourism. A few works have been published on radon levels in the South American mining. In this study, we investigated the radon transport process and its health hazard in two exhausted and abandoned mines in San Luis Province, Argentina. These mines were chosen because they have different physical configurations in their cavities, features which can affect the air flow patterns and radon concentrations. La Carolina gold mine (32 deg 48' 0'' S, 66 deg 60' 0'' W) is currently a blind end system, corresponding to a horizontal excavation into the side of a mountain, with only a main adit. Los Condores wolfram mine (32 deg 33' 25'' S, 65 deg 15' 20'' W) is also a horizontal excavation into the side of a mountain, but has a vertical output (a shaft) at the end of the main gallery. Three different experimental methodologies were used. Radon concentration measurements were performed by CR-39 nuclear track detectors. The distribution of natural radionuclide activities (40K, 232Th and 238U) was determined from rock samples collected along their main adits, using in laboratory gamma-ray spectrometry. The external gamma dose rate was evaluated using thermoluminescent dosimeters and a portable survey meter. The values for the 222Rn concentration ranged from 0.43 ± 0.04 to 1.48 ± 0.12 kBq/m3 in the Los Condores wolfram mine and from 1.8 ± 0.1 to 6.0±0.5 kBq/m3 in the La Carolina gold mine, indicating that, in this mine, the radon levels exceed up to four times the action level of 1.5 kBq/m3 recommended by the ICRP. The patterns of the radon transport process revealed that the La Carolina gold mine

  1. Land contamination and soil evolution in abandoned mine areas (Italy)

    Bini, Claudio; Wahsha, Mohammad; Spiandorello, Massimo

    2014-05-01

    In Italy ore research and exploitation are nearly exhausted since the end of the last century, leaving on the land a huge amount of mine waste, therefore provoking evident environmental damage including landscape, vegetation and the food chain, and a potential threat to human health. The increasing environmental consciousness of general population compelled Public Administrators to set down effective legislation acts on this subject (e.g. D.L. 152/2006), and more generally on environmental contamination. In this work we present the results of a survey carried out at several mixed sulphides mine sites in Italy, exploited for at least a millennium, and closed in the '60s of the last century. Biogeochemical analyses carried out on 50 soil profiles (mostly Entisols and Inceptisols) and vegetation in the proximal and distal areas of ore exploitation show metal concentrations overcoming legislation limits on average (Cu up to 3160 mg kg-1 , Pb up to 23600 mg kg-1, Zn up to 1588 mg kg-1, Fe up to 52,30 %). Ni, Cr and Mn concentrations, instead, are generally below the reference levels. Metal concentrations in native vegetation of the examined areas are moderately to highly elevated. Significant amounts of Cu, Pb, Zn in roots of Plantago major and Silene dioica, in leaves of Taraxacum officinale, and Salix spp, have been recorded. Essential elements, in particular, present Translocation Coefficients (TC) >1, with Mn>Zn>Cu>Fe. Toxic elements (Cd, Cr, Pb), instead, present TCplants, according to their role in mineral nutrition. The results obtained suggest the abandoned mine sites to represent actual natural aboratories where to experiment new opportunities for restoration of anthropogenically contaminated areas, and to study new pedogenetic trends from these peculiar parent materials. Moreover, the examined plants are genetically adapted to naturally metal-enriched soils, and therefore may be utilized in phytoremediation of contaminated sites. Furthermore, the institution

  4. Work plan for support to Upper East Fork Poplar Creek east end VOC plumes well installation project at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee

    Under the Resource Conservation and Recovery Act of 1976 guidelines and requirements from the Tennessee Department of Environment and Conservation (TDEC), the Y-12 Plant initiated investigation and monitoring of various sites within its boundaries in the mid-1980s. The entire Oak Ridge Reservation (ORR) was placed on the National Priorities List of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) sites in November 1989. Following CERCLA guidelines, sites within the ORR require a remedial investigation (RI) to define the nature and extent of contamination, evaluate the risks to public health and the environment, and determine the goals for a feasibility study (FS) or an engineering evaluation/cost analysis (EE/CA) of potential remedial actions. Data from monitoring wells at the east end of the Y-12 Plant have identified an area of groundwater contamination dominated by the volatile organic compound (VOC) carbon tetrachloride; other VOCs include chloroform, tetrachloroethene, and trichloroethene

  5. Spatial explicit assessment of rural land abandonment in the Mediterranean area

    Weissteiner, Christof J.; Boschetti, Mirco; Böttcher, Kristin; Carrara, Paola; Bordogna, Gloria; Brivio, Pietro Alessandro

    2011-10-01

    This study adopts the "syndrome approach", originally defined by the Potsdam Institute for Climate Impact Research (PIK), ( Downing et al., 2002) to assess and map rural land abandonment (RLA), that occurred during the period 1990-2005 within the wider Mediterranean area. The basic idea behind the syndrome approach is to describe change processes by archetypical, dynamic, and co-evolutionary patterns of civilization-nature interactions. In the frame of the Rural Exodus Syndrome the RLA can be interpreted as the occurrence of environmental degradation through the abandonment of traditional agricultural practices. Multi-source spatial data, including biophysical-related variables mainly derived from Earth Observation as well as socio-economical GIS-based data, were used to define proxies for expected underlying processes and drivers of the mentioned syndrome. The analysis of data is rooted in the fuzzy set theory and approximate reasoning techniques which allows for the handling of uncertain and imprecise knowledge of environmental systems. Generalized Conjunction/Disjunction operators (GCD) were applied to compute intermediate indicator score maps representing the conditions that may affect the RLA, and a bipolar operator was used to combine mandatory and favouring conditions with the aim of generating a RLA indicator. The indicator expresses the detailed location and severity, or degree, of the syndrome. The Northern Mediterranean was generally found to suffer from RLA to a distinctly higher degree than the Southern Mediterranean. Reported abandonment studies from the existing literature, the European CORINE land cover map, and the Less Favoured Areas (LFA) map all supported the findings by confirming plausibility through convergence of evidence from comparisons with different types of independent information. This spatially highly-detailed results obtained may be of particular interest to policy and decision makers involved in rural development planning in the

    2013-12-01

    Full Text Available A list of lichens from areas of zinc-lead ores in Southern Poland and a review of the characteristic lichen biota of these sites is provided. In spite of the devastated and heavy metal contaminated environment, a highly diverse epigeic and epilithic lichen biota was found, including species characteristic of various anthropogenic habitats, particularly zinc and lead enriched substrates (Diploschistes muscorum, Steinia geophana, Sarcosagium campestre, Vezdaea aestivalis and V. leprosa. Also, the high-mountain species Leucocarpia biatorella, as well as very rare in Europe Thelocarpon imperceptum, and several species categorized as very rare, endangered and protected in Poland were recorded. Crustose lichens are the most abundant; among fruticose forms Cladonia spp. predominate and Stereocaulon incrustatum is common.

  7. A Critique of Block on Abortion and Child Abandonment

    Jakub Bożydar Wiśniewski

    2010-05-01

    Full Text Available The present paper offers a critique of Block on the issues of abortion and child abandonment. Block regards aborting a fetus or abandoning a child as an instance of exercising one’s libertarian right of expelling trespassers from one’s private property. I argue that the above reasoning is flawed due to the lack of the appreciation of the fact that if one voluntarily initiates the causal chain which leads to someone else ending up on his property, the latter person cannot be considered a trespasser. Furthermore, in the light of the above observation, any direct effects resulting from that person’s eviction should be considered the responsibility of the property’s owner. All of this follows from the simple logical fact that in all links of the causal chain under consideration the owner is the ultimate causal agent.

  8. Abandoned coal mine tunnels: Future heating/power Supply centers

    Luo Pingjia; Chen Ning

    2011-01-01

    We have studied three plans for re-use of the abandoned mine roadway tunnels as an energy center.These are the thermostat plan,the thermal accumulator plan,and the CAES plan.Calculations show that the thermostat plan can provide over 15,000 m2 of building air-conditioning/heating load for each kilometer of roadway,but electric power is needed to run the system.Numerical research proved that the accumulation of hot water in the roadway for seasonal heating purposes (a temperature swing from 90 to 54 ℃) is a viable possibility.The CAES plan proposes using the discarded coal mine tunnel as a peaking power station with an energy storage density over 7000 kJ/m3.It can be concluded that presently abandoned coal mines could be reformed into future energy centers for a city.

  9. The problem of abandoned uranium tailings in northern Saskatchewan

    Two Saskatchewan tailings sites, Lorado and Gunnar, covering approximately 89 ha., were abandoned in the early 1960s leaving untreated tailings in lakes and depressions. This report reviews the literature on environmental conditions in abandoned uranium tailings and available managmenet and mitigation options, and identifies research requirements essential for proper treatment of these two sites. The recommended management plan includes isolation of the exposed tailings area from surface waters, stabilization of the exposed tailings surfaces, diversion of runoff around tailings, treatment of overflow water before release, and implementation of an environmental monitoring program. Revegetation appears to be a promising stabilization measure, but research is needed into propagation methods of appropriate native species. Studies of the existing geological and hydrological conditions at both sites, detailed characterization of the wastes, field testing of different surface treatment methods, and nutrient cycling investigations are also needed

  10. Abandoned mine shafts and levels in the British coalfields

    Davies, Christopher S.

    1988-07-01

    Industrial dereliction is a concern to all societies. In the United Kingdom the British government is trying to make its abandoned coalfields more attractive to new industry through a combination of land reclamation and job incentive programs. The most ambitious of these projects occurs in the South Wales Coalfield, which records 200 years of land defilement and the highest unemployment amplitudes in mainland Britain. In returning this area to a semblance of its previous state, problems arise over how best to fill and cap the many derelict pit shafts and abandoned shallow mines that riddle this region. This analysis reports on the methods of treatment used to achieve this end, along with the procedures used to minimize ground subsidence, water pollution, noxious gas emission, and the potential for physical injury. These environmental controls have application to the United States and Western Europe, where pockets of industrial blight are also symptomatic of a troubled local economy.

  11. Abandoned Highway Sections: an Opportunity for Requalification Landscape Projects

    Lucia Moretti

    2014-12-01

    Full Text Available With technology constantly improving, modern highways can nowadays be built through terrains where construction used to be either technically infeasible or too costly. While this results in faster connections and shorter commuting times, it leaves the abandoned historic routes behind without any use. This workshop was aimed at developing solutions for the requalification of abandoned highway sections, focusing on the example of the Autostrada del Sole which bypasses the little town of Vado, Bologna. A concept of converting the section into a Sole Park - a park which offers both relaxation and amusement elements - was developed in order to attract visitors from the neighboring villages and the high-speed highway. Within this context, potential locations for lookouts were identified, giving stunning vistas of the Tuscan-Emilian landscape.

    Whiteside, R.; Pawlowicz, R.; Whitehead, L.; Arnseth, R.

    2002-02-25

    In 2000, Bechtel Jacobs Company LLC (BJC) contracted Tetra Tech NUS, Inc. (TtNUS) and their sub-contractor, Texas World Operations, Inc. (TWO), to plug and abandon (P&A) 111 wells located in the Melton Valley area of Oak Ridge National Laboratory (ORNL). One hundred and seven of those wells were used to monitor fluid movement and subsurface containment of the low level radioactive liquid waste/grout slurry that was injected into the Pumpkin Valley Shale Formation, underlying ORNL. Four wells were used as hydrofracture injection wells to emplace the waste in the shale formation. Although the practice of hydrofracturing was and is considered by many to pose no threat to human health or the environment, the practice was halted in 1982 after the Federal Underground Injection Control regulations were enacted by United States Environmental Protection Agency (USEPA) making it necessary to properly close the wells. The work is being performed for the United States Department of Energy Oak Ridge Operations (DOE ORO). The project team is using the philosophy of minimum waste generation and the principles of ALARA (As Low As Reasonably Achievable) as key project goals to minimize personnel and equipment exposure, waste generation, and project costs. Achievement of these goals was demonstrated by the introduction of several new pieces of custom designed well plugging and abandonment equipment that were tested and used effectively during field operations. Highlights of the work performed and the equipment used are presented.

  15. Identification of Risks Pertaining to Abandoned Housing Projects in Malaysia

    2015-01-01

    Full Text Available Housing industry is one of the most dynamic, risky, and challenging industries. In Malaysia, this industry has a poor reputation for managing risks, with many major projects failing to be completed within the allotted time. Due to the inherent risks involved in construction projects, it is essential to recognize the risks that cause problems associated with abandoned housing projects. Therefore, this study aims to identify the risks that contribute to issues of abandoned housing projects and to propose mitigation strategies. The methodologies used in this study are combination of qualitative and quantitative methods of literature review, questionnaire survey, and interview. The results show that many risks are involved in housing project, including risks related to environmental impacts, construction, politics, law, management, finance, materials, and economy, of which the probability of risks from unexpected ground condition, project delays, bureaucracy, contractual disputes between developer and landlord, weakness in management by inexperience developer, and financial crisis is very high. It was also found that all relevant parties involved in housing industry are required to have extensive cooperation in advance and should perform systematic risk management strategies in order to mitigate the risks leading to problems associated with abandoned housing projects.

  16. Secondary Forests from Agricultural Abandonment in Amazonia 2000-2009

    Morton, Douglas

    2010-01-01

    Ongoing negotiations to include reducing emissions from tropical deforestation and forest degradation (REDD+) in a post-Kyoto climate agreement highlight the critical role of satellite data for accurate and transparent accounting of forest cover changes. In addition to deforestation and degradation, knowledge of secondary forest dynamics is essential for full carbon accounting under REDD+. Land abandonment to secondary forests also frames one of the key tradeoffs for agricultural production in tropical forest countries-whether to incentivize secondary forest growth (for carbon sequestration and biodiversity conservation) or low-carbon expansion of agriculture or biofuels production in areas of secondary forests. We examined patterns of land abandonment to secondary forest across the arc of deforestation in Brazil and Bolivia using time series of annual Landsat and MODIS data from 2000-2009. Rates of land abandonment to secondary forest during 2002-2006 were less than 5% of deforestation rates in these years. Small areas of new secondary forest were scattered across the entire arc of deforestation, rather than concentrated in any specific region of the basin. Taken together, our analysis of the satellite data record emphasizes the difficulties of addressing the pool of new secondary forests in the context of REDD+ in Amazonia. Due to the small total area of secondary forests, land sparing through agricultural intensification will be an important element of efforts to reduce deforestation rates under REDD+ while improving agricultural productivity in Amazonia.

  17. Traditional olive orchards on sloping land: sustainability or abandonment?

    Duarte, Filomena; Jones, Nádia; Fleskens, Luuk

    2008-11-01

    Traditional olive orchards account for a large share of the area under olives in the EU, particularly in marginal areas, like those analysed in the OLIVERO project. In general, traditional olive growing can be described as a low-intensity production system, associated with old (sometimes very old) trees, grown at a low density, giving small yields and receiving low inputs of labour and materials. Though such systems are environmentally sustainable, their economic viability has become an issue, since EU policies favour more intensive and competitive systems. Orchards that have not been intensified seem to be threatened by the recent reform of the EU olive and olive oil policy, as income support has been decoupled from production. The main purpose of this paper is to identify the present constraints to traditional olive growing, and to recommend some private and public interventions to prevent its abandonment. During the OLIVERO project, traditional olive production systems were identified and described in five target areas (Trás-os-Montes--Portugal, Cordoba and Granada/Jaen--Spain, Basilicata/Salerno--Italy, and West Crete--Greece). The causes and consequences of abandonment are discussed, based on the analysis of the costs and returns, which revealed that these systems are barely economically sustainable. Their viability is only assured if reduced opportunity costs for family labour are accepted, and the olive growing is part-time. Based on these results, recommendations are made to prevent the abandonment of traditional olive growing and to preserve its environmental benefits. PMID:17923250

  18. A Coupled Economic and Physical Model of Coastal Adaptation and Abandonment: Are human occupied coastlines a bubble waiting to burst?

    McNamara, D.; Keeler, A.

    2011-12-01

    Policy discussions of adaptation by coastal residents to increasing rates of sea level rise and changing frequency of damaging storms have focused on community land use planning processes. This view neglects the role that market dynamics and climate change expectations play in the way coastal communities choose among risk mitigation options and manage land use decisions in an environment of escalating risks. We use a model coupling physical coastal processes with an agent-based model of behavior in real estate and mitigation markets to examine the interplay of climate-driven coastal hazards, collective mitigation decisions, and individual beliefs. The physical component model simulates barrier island processes that respond to both storms and slow scale dynamics associated with sea level rise. The economic component model is an agent-based model of economic behavior where agents are rational economic actors working off different assessments of future climate-driven events. Agents differentially update their beliefs based on a) how much emphasis they give to observed coastal changes and b) how much weight they give to scientific predictions. In essence, agents differ along a spectrum of how much they believe that the past is the best guide to the future and how quickly they react to new information. We use the coupled model to explore three questions of interest to coastal policy. First, how do the interplay of costal processes, beliefs, and mitigation choices affect the level and stability of real estate prices? Second, how does this interplay affect the incentives for community investments in shoreline protection? Third, how do expectations and reactions to observed events, as well as mitigation investments, affect the built environment in circumstances when climate risks reach very high levels? This last question relates to a key aspect of climate change adaptation on the coast - when does mitigation give way to abandonment as an optimal adaptation strategy

  19. Parents do the Work Well to Effectively Promote Family-kindergarten Coeducation%做好家长工作有效促进家园合育

    家庭与幼儿园作为幼儿教育的主体,共同承担着教育幼儿的任务,二者缺一不可.然而当前家庭教育仍然存在一些问题,做好家长工作,是幼儿园取得发展的有力保障.一个园所,必须得到家长的支持,它的发展才是有生命力的,否则不会持久.所以,在幼儿园的日常工作中,我们应充分认识到家长工作的重要性,实现家园合育.现阶段有必要对家园合育的含义做系统的解释,阐述家园合育的重要性并提出相应的策略,为家园合育的顺利开展提供依据.%The family and the kindergarten are two indispensible and collaborative entities for child education. However, current family education is not without problems. Therefore, for the sake of its good development, the kindergarten should keep a good relationship and well cooperate with the family. Only when it gains support from parents of the family can the kindergarten retains its vitality. The importance of the role played by parents of the family in family-kindergarten coeducation should be fully observed. This paper gives a systematic interpretation of family-kindergarten coeducation and proposes some corresponding strategies, hoping to provide some reference for further implementing family-kindergarten coeducation.

  20. Potential for offshore geothermal developments using deep gas wells

    Teodoriu, C.; Falcone, G. [Technische Univ. Clausthal, Clausthal-Zellerfeld (Germany). ITE

    2013-08-01

    The development of geothermal resources is steadily increasing as operators meet the challenge of maximising the temperature difference between production and injection wells, while minimising the wellhead temperature of the latter. At present, the minimum working wellhead temperature reported for the heat-to-electricity conversion cycles is limited to about 80 C. The cycle efficiency can be improved by reducing the injection temperature, which is the temperature at which the fluid exits the process. This paper evaluates the potential for generating electricity with a subsea geothermal plant using the difference between downhole reservoir temperature and that of the cold seawater at the mud line. The temperature in the world's oceans is relatively constant, ranging from 0 to 4 C at around 400 meters water depth. The use of these lower offshore water temperatures may help boost geothermal energy development. Deep gas resources are considered to be held within reservoirs below 4600 meters (15000 feet) and are relatively undeveloped as the risks and costs involved in drilling and producing such resources are extremely high. These deep resources have high reservoir temperatures, which offer an opportunity for geothermal exploitation if a new development concept can be formulated. In particular, the well design and reservoir development plan should consider reutilising existing well stock, including dry and plugged and abandoned wells for geothermal application once the gas field has been depleted. The major risks considered in this study include alternative uses of wells in no flow or rapid depletion situations. Reutilisation of the wells of depleted gas reservoirs will invariably lead to lower geothermal development costs compared with starting a geothermal campaign by drilling new wells. In particular, the well design and reservoir development plan should consider reutilising existing well stock, including dry and plugged and abandoned wells for geothermal

  1. Lymphedema Precautions: Time to Abandon Old Practices?

    Ahn, Soojin; Port, Elisa R

    2016-03-01

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 46-year-old premenopausal woman with a body mass index of 21 was found on screening mammography to have a new, approximately 1-cm spiculated mass with associated calcifications in the upper outer quadrant of the left breast. Stereotactic core biopsy showed a focus of invasive duct carcinoma, strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2, with associated ductal carcinoma in situ. Clinical examination revealed no palpable mass or axillary lymphadenopathy. She underwent a left lumpectomy with seed localization and sentinel lymph node biopsy. Final pathology revealed an 8-mm well-differentiated invasive carcinoma without lymphovascular invasion and intermediate grade ductal carcinoma in situ. The margins were clear, and three sentinel lymph nodes were negative for metastasis. The 21-gene recurrence score was 10, suggesting a 7% risk of 10-year distant recurrence with adjuvant endocrine treatment. After the completion of adjuvant radiotherapy (42.50 Gy in 16 fractions to the breast), the patient has returned for a follow-up visit. She is a professional violinist and would like to know what she can do to prevent lymphedema on her upcoming flight to Vienna. PMID:26712226

    众所周知,教育教学工作是学校的中心工作,教学质量是学校的生命线。高职高专院校的许多学生在入学时成绩相对于本科院校的学生低一些,在心理上和学习上都存在一定的问题,做好这一部分学生的教育教学工作不但对于学生本人有用,而且对学校未来的发展都有着十分重要的现实意义。作为高职高专院校里的每一位班主任老师要努力地从加强与学生的交流沟通,打消学生的心理压力;帮助学生明确学习目的与目标,进行职业规划;学习上要高标准严要求,生活上要多关心和爱护;建好班级干部队伍,抓好领头羊的作用;要客观公正、赏罚分明,做好后进生的转化工作,就会带好班级。%It is known to all that teaching is a school's central workand good quality of teaching is the lifeline.There are many students in higher vocational colleges whose entrance examination records are a little lower than those undergraduate students. Also,they are more likely to have difficulties in their mentality or studies.Therefore,perfecting educational work among those students not only benefits students themselves but also has a profound and a far reaching significance for our college's develop-ment.For every class adviser in higher vocational colleges,it's important to strengthen the communication with students so that their stress can be reduced.What's more,it's every class advisers'duties to help students clearify their study targets and have a career plan.In studies,it's necessary for students to set a high standard under strict requirements.In daily lives,it's better for teachers to care and protect more of those students.In addition,we should build up the managerial role of class committee and then make them to play the leading role of the class.Only if teachers become more objective in rewards and punishments can they do a perfect job in developing students.And then,do a better

  3. Well Spacing for Horizontal Wells

    C.D.S. Keuengoua

    2011-06-01

    Full Text Available In the developing phase of a hydrocarbon reservoir and planning for drilling the production wells, it is necessary to drill the wells in an appropriate spacing to achieve maximum economic revenues during the reservoir life span. Well spacing which is the real location and interrelationship between producing oil or gas wells in an oil field is an important parameter. It is determined for the maximum ultimate production of a given reservoir and should be taken in consideration during well planning to avoid drilling of unnecessary wells. This study presents the concept of drainage area on horizontal well and horizontal productivity indices with different equations and their applications. A user friendly Excel Spreadsheet program was developed to calculate the productivity values of horizontal wells using three major available productivity equations. Also, the developed spreadsheet program was used to evaluate the effect of well spacing on the productivities of horizontal wells using productivity index approach and drainage area concept. It also helps to review the comparison between vertical and horizontal wells spacing based on drainage area concept. This program was validated, and then was used to study the effect of horizontal well length on the ratio of horizontal well productivity to vertical well productivity. The results show that higher ratio of horizontal well productivity to vertical well productivity values are obtained with increase length of the horizontal well. It is a very useful tool for making decision about the application of well spacing for horizontal wells.

  4. THE REMEDIATION OF ABANDONED IRON ORE MINE SUBSIDENCE IN ROCKAWAY TOWNSHIP, NEW JERSEY; SEMIANNUAL

    This report represents the sixth Semi-Annual Technical Progress Report issued in connection with the subsidence remediation projects undertaken by Rockaway Township in Morris County, New Jersey. This report provides a summary of the major project work accomplished during this reporting period and contemplated for the subsequent reporting period. This report is issued as part of the project reporting provisions set forth in the Cooperators Agreement between the United States Government-Department of Energy, and Rockaway Township. The purpose of the Cooperators Agreement is for the Department of Energy to provide technical and financial assistance in a coordinated effort with Rockaway Township to develop and implement a multi-phased plan to remediate ground stability problems associated with abandoned mining activity. Primarily during the 1800's, extensive iron ore mining and prospecting was undertaken in Rockaway Township, part of the Dover District Mining region in Morris County. The abandoned mining activity has resulted in public safety hazards associated with ground collapse and surface subsidence features evolving in both developed and undeveloped areas within Rockaway Township. At the White Meadow Mine site, after amended specifications were prepared and continued negotiations took place with the Property Owner, the property ownership was transferred during the reporting period. As a result in the change in property ownership, the remediation project was then to be done by the new Property Owner out of the responsibility of Rockaway Township under this Cooperators Agreement. At the Mt. Hope Road subsidence, surface monitoring was conducted at the work area and adjacent areas after the January 2000 construction effort. At the Green Pond Mine site at the Township Compost Storage Facility, no additional field work was undertaken during this reporting period subsequent to the previous completion of the geophysical survey. With the termination of the White Meadow

  6. Pharma TARP: A Troubled Asset Relief Program for Novel, Abandoned Projects in the Pharmaceutical Industry

    Tamas Bartfai

    2011-01-01

    Full Text Available Within days of each other, Pfizer, Merck, and GlaxoSmithKline announced that they will focus on a few therapeutic areas only and abandon others entirely. Pfizer alone will close well over a hundred drug development projects that have reached two-thirds of the way to launch. The programs are deemed to be too risky and not lucrative enough for Big Pharma in the current climate. Society has a real need for the drugs that are no longer going to be developed for, among others, drug-resistant epilepsy, neuropathic and cancer pain, type-2 diabetes, obesity, and schizophrenia. The authors propose a radical response by the U.S. government and the National Institutes of Health to rescue these abandoned projects, and to continue selected programs for drug approval by the U.S. Food and Drug Administration and the European Medicines Agency. The investment required is small compared to the Troubled Asset Relief Program bank bail out, but the return on investment in financial terms and in satisfying societal needs makes this proposal attractive.

  7. Research on mechanism of groundwater pollution from mine water in abandoned mines

    2008-01-01

    In order to understand the mechanism and regularity of the groundwater contamination from mine water of abandoned mines, experiments were conducted on an abandoned coal mine in Fuxin, a representative city with lots of mine water in northeast China. The groundwater pollution from different contaminants of coal-mining voids (total hardness, SO2-4, Cl and total Fe) and pollution factors transportation situation in the coal rock were simulated by soil column experiment under the conditions of mine water leaching and main water leaching (similar to rainwater leaching), and the water-rock interaction mechanism was discussed during mine water infiltration through saturated coal rock by application of principle of mass conservation, based on physical properties of coal rock, as well as monitored chemical composition. The results show that, compared with the clear water leaching process, trends of change in pollutant concentrations presented different characteristics in the mine water leaching process. Groundwater is contaminated by the water rock interactions such as migration & accumulation, adsorption & transformation,dissolution & desorption and ion exchange during the mine water permeation. The experiments also suggest that at first dissolution rate of some kinds of dissoluble salts is high,but it decreases with leaching time, even to zero during both the mine water leaching and main water leaching.

    1996-12-31

    Several highwall pits of an abandoned surface mine in the Springfield Coal Member (Pennsylvanian) are currently occupied by ponds with a total area of approximately 2.3 x 10{sup 4} m{sup 2}. These ponds are adjacent to an abandoned underground mine (Patoka Valley Coal and Coke Company No. 1 Mine) in the same coalbed. The mine underlies about 0.3 km{sup 2} and contains approximately 4 x 10{sup 5} m{sup 3} of flooded voids. Monitoring of water levels in wells that are screened in the mine and of the levels of adjacent ponds reveal that average hourly levels vary in unison across a range of less than one meter. The mean potentiometric level of the mine-aquifer, the neighboring ponds, and an artesian spring that issues through the outcrop of the coalbed, are at elevations of about 163 m above sea level. Long-term monitoring and a field experiment that involved pumping of a pond indicated that the mine was connected to two of the ponds and served to recharge, rather than discharge, the ponds. The monitoring and field experiment also allowed determination of the mine aquifers barometric efficiency (0.3) and its storativity (2 x 10{sup -3}) . A water-balance calculation indicates that the average recharge rate of the mine is about 0.1 mm/day.

  9. An engineering approach to predict subsidence likelihood over abandoned coal mines in Illinois

    In this paper, the authors attempt to develop engineering based approaches for estimating safety factors against pillar and floor failures and predicting likelihood of subsidence events over abandoned coal mines in Illinois. There are two critical problems involved in the analysis: determination of geotechnical properties, and consideration of time effect. The authors attempt to solve the problems by generating hypotheses, which are used to modify existing engineering models for estimating pillar and floor safety factors. The modified models are validated using data from two well established databases of subsidence events over active and abandoned mines in Illinois. The data analysis suggests that most of the trough type subsidence events in Illinois were caused by floor failures rather than pillar failures. The subsidence incubation period seems to be directly related to initial floor safety factors at the time of mining. This correlation can be used to predict the likelihood of subsidence and to assess subsidence risks within both spatial and temporal contexts where detailed mine maps are available

  14. How well do radon mitigation strategies work?

    Naturally occurring radon in homes can't be completely avoided, but it can be minimized. Indoor air quality researchers compared results of six popular ways to mitigate radon in houses in the Spokane River Valley and New Jersey. Over the course of the past decade, Americans have become aware of the health hazards from radon, a naturally occurring gas that can enter a home through a variety of pathways from the surrounding terrain. Recent research carried out at Lawrence Berkeley Laboratory (LBL) and elsewhere suggests that radon mitigation is feasible but requires long-term monitoring to ensure lasting effectiveness. These studies compare the selection, installation, and performance evaluations of several common radon mitigation strategies

    Paolino, Melisa; Arrossi, Silvina

    2012-12-01

    Adequate follow-up and treatment of women with high-grade squamous intraepithelial lesion (HSIL) and cancer is key in reducing cervical cancer mortality. This research study aims to analyze the magnitude of abandonment in the follow-up and treatment process, as well as the reasons for this abandonment, in women with HSIL who received care in public health services in the province of Jujuy in 2010. Secondary sources were analyzed and women were interviewed in their homes. The abandonment rate within the study population was 23.5%. Among these women, 40.5% mentioned organizational problems in the health care system as a reason for abandoning and 30.9% mentioned subjective reasons. Our results have been used in the reorganization of the follow-up and treatment process being carried out in the province. PMID:23681458

  17. Mapping Secondary Forest Succession on Abandoned Agricultural Land with LiDAR Point Clouds and Terrestrial Photography

    Natalia Kolecka

    2015-06-01

    Full Text Available Secondary forest succession on abandoned agricultural land has played a significant role in land cover changes in Europe over the past several decades. However, it is difficult to quantify over large areas. In this paper, we present a conceptual framework for mapping forest succession patterns using vegetation structure information derived from LiDAR data supported by national topographic vector data. This work was performed in the Szczawnica commune in the Polish Carpathians. Using object-based image analysis segments of no vegetation, and sparse/dense low/medium/high vegetation were distinguished and subsequently compared to the national topographic dataset to delineate agricultural land that is covered by vegetation, which indicates secondary succession on abandoned fields. The results showed that 18.7% of the arable land and 40.4% of grasslands, that is 31.0% of the agricultural land in the Szczawnica commune, may currently be experiencing secondary forest succession. The overall accuracy of the approach was assessed using georeferenced terrestrial photographs and was found to be 95.0%. The results of this study indicate that the proposed methodology can potentially be applied in large-scale mapping of secondary forest succession patterns on abandoned land in mountain areas.

  18. Relief for marginal wells is better than energy tax

    By increasing production costs and reducing petroleum prices, President Bill Clinton's proposed energy tax would increase marginal well abandonments and hasten the decline of the US oil and gas industry. Instead, the US needs tax law changes to help counteract the increasing number of oil and gas well abandonments in the lower 48 states. The proposed tax would create potential difficulties, while three incentives could be introduced to reduce abandonments and at the same time preserve US government tax revenues that otherwise would be lost. Eliminating the net income limitation on percentage depletion allowances on wells that would otherwise be abandoned would be a great help for marginal well operators. Extended enhanced oil recovery (EOR) credits and broader investment tax credits could also serve the dual purpose of keeping marginal wells operating longer and generating more federal tax revenues. A marginal well investment tax credit should be provided that is not just a credit for incremented investments that exceed investment in prior years. An investment tax credit based on out-of-pocket costs of production, targeted for marginal wells, would be an important incentive to invest in, and continue to maintain, these properties. (author)

  1. Measures of Vegetation Restoration in Abandoned Mined Lands

    2008-01-01

    By 2004, the occupied and disturbed land area had reached 3.393 million ha by mining, of which forest land took 532 000 ha; In addition, mining also caused 3.721 million -5.316 million ha of degraded forests and woodlands. The impact of mining on environment is multi-fold and deep. Thus it is necessary and significant to approach effective methods to speed up vegetation restoration in abandoned mined lands. Phytoremediation is a relatively new technology (in the lastest decade) and the numbers of plant spec...

    Presently, the BLM (Bureau of Land Management) has identified a multitude of abandoned mine sites in primarily Western states for cleanup. These sites are prioritized and appropriate cleanup has been called in to reclaim the sites. The task is great in needing considerable amounts of agency resources. For instance, in Colorado alone there exists an estimated 23,000 abandoned mines. The problem is not limited to Colorado or to the United States. Cooperation for reclamation is sought at local, state, and federal agency level to aid in identification, inventory, and cleanup efforts. Dangers posed by abandoned mines are recognized widely and will tend to increase with time because some of these areas are increasingly used for recreation and, in some cases, have been or are in the process of development. In some cases, mines are often vandalized once they are closed. The perpetrators leave them open, so others can then access the mines without realizing the danger posed. Abandoned mine workings often fill with water or oxygen-deficient air and dangerous gases following mining. If the workings are accidentally entered into, water or bad air can prove fatal to those underground. Moreover, mine residue drainage negatively impacts the local watershed ecology. Some of the major hazards that might be monitored by higher-resolution satellites include acid mine drainage, clogged streams, impoundments, slides, piles, embankments, hazardous equipment or facilities, surface burning, smoke from underground fires, and mine openings.

  3. Dynamics of phosphorus fractions after land-use abandonment in relation to carbon, nitrogen, and microbial community composition

    Spohn, Marie

    2014-05-01

    Former agricultural land-use has strong legacy effects on biogeochemical cycles as well as on plant and microbial community composition in secondary ecosystems. Since many forests and grasslands have previously been cultivated it is important to understand long-term effects of former arable land use on these ecosystems. We studied the temporal dimension of the impact of former agricultural land use on soil total organic C (TOC), nitrogen (N), phosphorus (P) fractions, and microbial community structure in two chronosequences of abandoned vineyards, differing in exposition and slope. We found that more TOC accumulated in soils of south- than in southwest-exposed sites, which can be attributed to the drier microclimate that decreases organic matter decomposition. TOC concentrations were significantly positive correlated with total nitrogen (TN) concentrations (R=0.99, pslow depletion of P from the soil organic matter (SOM) after cessation of cultivation. This suggests that SOM is an effective intermediate storage of fertilizer-derived P, which slowly releases P. In contrast, labile P concentrations decreased quickly during the first 25 years of land use-abandonment. A linear relation between microbial C and TOC (R=0.83, pfertilizer-derived P, which slowly releases P, but still contains high amounts of P even more than 100 years after land-use abandonment. This has important implications for conservation management as it shows that organic P stocks have to be taken into account for estimating the development potentials of formerly cultivated sites for plant conservation.

    In my research, I examined abandonment fears in persons with Alzheimerâ s disease at the Salem Veterans Affairs adult day care center. I observed fifty hours at the center, and conducted open-ended interviews with two of the participants and their respective caregivers. These two participants (Ellen and Opel) at the center expressed abandonment fears much more frequently than any of the other participants. I found that most of the time, these two women would express their abandonment f...

    This document is a compendium of results of the calendar year 1994 Monitor Well Inspection and Maintenance Program at the Department of Energy Y-12 Plant in Oak Ridge, Tennessee. This report documents the work relating to well inspections and maintenance requests. Inspections are implemented in order to better assess the condition and maintenance needs of wells that are actively being monitored. Currently this approach calls for inspecting all wells on a routine (annual or triennial) basis which are: (1) in an active sampling program; (2) included in a hydrologic study; or (3) not in service, but not scheduled for plugging and abandonment. Routine inspections help to ensure that representative groundwater samples and hydrologic data are being collected, and contribute to the life expectancy of each well. This report formally presents well inspection and maintenance activities that were conducted at the Y-12 Plant during 1994. All inspections were conducted between April and December

  8. Soil erosion as a consequence of wildfires on recently abandoned citrus orchards in eastern Spain

    A. Cerdà; F. A. González-Peñaloza; Burguet, M.; P. Pereira

    2013-01-01

    Fire is a natural factor in the evolution of Earth ecosystems. Due to land abandonment wildfire are widespread in Mediterranean Type Ecosystems, which contribute to increase the soil erosion rates. Fire is also found in recently abandoned citrus orchards due to the quick vegetation recovery and the dry biomass found after 2 years of abandonment. Rainfall simulation experiments (1 hour at 45 mm h-1 in a plot of 0.25 m2) show that although land abandonment on irrigated citrus orchards reduces t...

  9. Potential hydrologic characterization wells in Amargosa Valley

    More than 500 domestic, agricultural, and monitoring wells were identified in the Amargosa Valley. From this list, 80 wells were identified as potential hydrologic characterization wells, in support of the US Department of Energy (DOE) Underground Test Area/Remedial Investigation and Feasibility Study (UGTA/RIFS). Previous hydrogeologic studies have shown that groundwater flow in the basin is complex and that aquifers may have little lateral continuity. Wells located more than 10 km or so from the Nevada Test Site (NTS) boundary may yield data that are difficult to correlate to sources from the NTS. Also, monitoring well locations should be chosen within the guidelines of a hydrologic conceptual model and monitoring plan. Since these do not exist at this time, recompletion recommendations will be restricted to wells relatively close (approximately 20 km) to the NTS boundary. Recompletion recommendations were made for two abandoned agricultural irrigation wells near the town of Amargosa Valley (previously Lathrop Wells), for two abandoned wildcat oil wells about 10 km southwest of Amargosa Valley, and for Test Well 5 (TW-5), about 10 km east of Amargosa Valley

  10. Characterization and effectiveness of remining abandoned coal mines in Pennsylvania

    Under an approved remining program, mine operators can remine abandoned coal mines without assuming legal responsibility for treatment of the previously degraded water, as long as the discharging waters are not further degraded and other regulatory requirements are satisfied. A US Bureau of Mines review of 105 remining permits in Pennsylvania indicates that remining results in substantial reclamation of abandoned mine lands, utilization of significant quantities of coal, and reduction of contaminant loads (acidity and iron) from degraded mine drainage discharges. Normality tests performed on the water quality and flow data indicate generally nonnormal distributions and extreme right-skewness tending toward lower values. The water quality of underground coal mines was observed to be more highly degraded in terms of acidity, iron, and sulfate than that of surface coal mines. The optimum baseline sampling scenario is 12 months in duration at a frequency of one sample per month. Analysis of water quality and flow rates before and after remining indicates that a majority of the mines exhibited either no change or a significant decrease in pollution rate because of remining. The discharge flow rate was the dominant controlling factor when the post-remining contaminant load was significantly better or worse than the baseline (pre-mining) load

  11. [Xenophobia and experienced abandonment--a depth-hermeneutic analysis of a single case].

    Taubner, Svenja; Hasper, Fritz; Wahl, Klaus

    2013-01-01

    A single case study is presented from a feasibility study on social, psychic and neurobiological causes of violence in adolescence focusing on right-wing extremist and xenophobic youth. Results from psychological assessments and a structured biografical reconstruction are analyzed. The case illustrates a typical developmental path of a right-wing, xenophobic and violent male adolescent who experienced early and repeated exclusion and social marginalization. Results from psychological testing demonstrated additional developmental risk factors, such as disorganized attachment representations and low mentalizing abilities. A depth-hermeneutic analysis ofa sequence during the attachment interview as well as a reflection of the research setting further illustrates how experiences of exclusion are re-enacted by a combination of fear of abandonment and aggression.

  12. L’abandon et l’appel, ou l’optimisme paradoxal de Graham Greene dans The Power and the Glory Abandoned and Called, or Graham Greene’s Paradoxical Optimism in The Power and the Glory

    René Gallet

    2007-01-01

    Full Text Available The Power and the Glory is often seen as a pessimistic, if not tragic, work. However, this fails to consider Greene’s little-known statement to the contrary, as well as important aspects of the novel, one of them being the idea of “glory” in the title. In the narrative itself, a fragmented presence of beauty can be discovered as early as the opening scene, and more particularly within Mr Tench’s seedy universe. Two contrasting worlds are thus intermingled from the very beginning, and the rest of the novel is interspersed with similar examples. A related observation can be made about the feeling of abandonment voiced by most of the characters. When examined more closely, the feeling turns out to be highly ambiguous, and not always devoid of bad faith. It should be contrasted with the repeated phenomenon of calls to responsible action. The most striking one is also found in the opening scene, where the fugitive priest is reminded of his duty by the mysterious, though seedy looking, native child. And through the priest a call is addressed to Mr Tench, who fails to perceive anything. This call to his repressed conscience is repeated in the final scene when he witnesses the priest’s execution. Newman’s understanding of man’s condition probably underlies such contrasts “between the beautiful and the treacherous”. The degraded world in which most characters evolve is not to be isolated from the experience of conscience which both confirms the reality of this negative state of affairs and, in varying degrees, distances the characters from it.

  16. Coastal rainforest boundary dynamics during the late Holocene in monsoonal Australia: evidence from radiocarbon dates of abandoned nests of Orange-footed Scrubfowl

    The late Holocene history of monsoon rainforest retreat was explored by radiocarbon dating abandoned Orange-footed Scrubfowl (Megapodius reinwardt Gaimard) nests in coastal savannas in the Northern Territory of Australia. Previous work has demonstrated that in savanna environments this rainforest bird can not build nor maintain the large heaps of soil and leaf litter that it uses for nests. Excavations of two earthen mounds in a savanna habitat verified that they were abandoned Scrubfowl nests, and not Aboriginal middens, given their lack of stratigraphy, non-sequential dating of charcoal in a vertical profile, and absence of archaeological material. Radiocarbon dates of material taken from the surface of abandoned nests were determined for three sites on the coast of the Northern Territory. These analyses revealed that for all three sites, rainforests have contracted within the last 1800 years BP. On Elcho Island an abandoned nest was found to contain the land snail Xanthomelon spheroidea Le Guillou (known to prefer rainforest habitat) with a modern radiocarbon age, suggesting recent contraction of rainforest. The results of this study further weaken the theory that Aboriginal burning was a major cause of rain forest fragmentation in the monsoon tropics, and possibly elsewhere in Australia

  18. Solution of underground mine gas emissions on surface of abandoned mining sites where steep deposited coal seams have been exploited

    The solution of uncontrolled gas emissions from abandoned underground coal mine sites in Ostrava-Karvina coal-field to surface ground in connection with old mine shafts and drifts and with old mining workings in horizontal and inclined coal seams has many forms. It varies according to geological and mining conditions and the disposition of the site surface. Since four years the gas emission risk has appeared in the area of former exploited vertical coal seams within the historical centre of Orlova town, which is protected by State Monument Protection office. A project based on such special nature of mining-geological and urban conditions was elaborated and already implemented. (authors)

  19. Why do leaf-tying caterpillars abandon their leaf ties?

    Michelle Sliwinski

    2013-09-01

    Full Text Available Leaf-tying caterpillars act as ecosystem engineers by building shelters between overlapping leaves, which are inhabited by other arthropods. Leaf-tiers have been observed to leave their ties and create new shelters (and thus additional microhabitats, but the ecological factors affecting shelter fidelity are poorly known. For this study, we explored the effects of resource limitation and occupant density on shelter fidelity and assessed the consequences of shelter abandonment. We first quantified the area of leaf material required for a caterpillar to fully develop for two of the most common leaf-tiers that feed on white oak, Quercus alba. On average, Psilocorsis spp. caterpillars consumed 21.65 ± 0.67 cm2 leaf material to complete development. We also measured the area of natural leaf ties found in a Maryland forest, to determine the distribution of resources available to caterpillars in situ. Of 158 natural leaf ties examined, 47% were too small to sustain an average Psilocorsis spp. caterpillar for the entirety of its development. We also manipulated caterpillar densities within experimental ties on potted trees to determine the effects of cohabitants on the likelihood of a caterpillar to leave its tie. We placed 1, 2, or 4 caterpillars in ties of a standard size and monitored the caterpillars twice daily to track their movement. In ties with more than one occupant, caterpillars showed a significantly greater propensity to leave their tie, and left sooner and at a faster rate than those in ties as single occupants. To understand the consequences of leaf tie abandonment, we observed caterpillars searching a tree for a site to build a shelter in the field. This is a risky behavior, as 17% of the caterpillars observed died while searching for a shelter site. Caterpillars that successfully built a shelter traveled 110 ± 20 cm and took 28 ± 7 min to find a suitable site to build a shelter. In conclusion, leaf-tying caterpillars must frequently

  20. ENVIRONMENTAL ASSESSMENT OF OKLAHOMA ABANDONED DRILLING AND PRODUCTION SITES AND ASSOCIATED PUBLIC EDUCATION/OUTREACH ACTIVITIES

    Mike Terry

    2002-03-01

    The U.S. Department of Energy has participated with the Oklahoma Energy Resource Board (OERB) since 1995 by providing grant funding for on-going work in both environmental assessment of abandoned oilfield exploration and production sites and associated public education/outreach activities. The OERB, a state agency created in 1993 by the Oklahoma legislature, administers programs funded by an assessment of one tenth of one percent on all oil and natural gas produced and sold in the state of Oklahoma. Approximately one half of the funds are used to assess and remediate abandoned oilfield sites and the other half are being used to educate about the importance of the oil and natural gas industry and OERB's environmental efforts. Financial participation through grant funding by the U.S. D.O.E. has been $200,000 annually which represents approximately 3 percent of OERB's private funding. Most of OERB's revenues come from an assessment of 1/10th of 1% on the sale of crude and natural gas in Oklahoma. The assessment is considered voluntary in that any interest owner may ask for a refund annually of their contributions to the fund. On average, 95% of the assessment dollars have remained with OERB, which shows tremendous support by the industry. This Final Report summarizes the progress of the three year grant. The purpose of this three-year project was to continue the progress of the OERB to accomplish its environmental and educational objectives and transfer information learned to other organizations and producing states in the industry.

    This work exploited the application of Haar wavelet approach to sedimentary microfacies analysis using log data and gradually abandoned channel facies identifying. This method first, uses wavelet transformation to separate noise and minutiae from large scale patterns for log data. Then normal channels and gradually abandoned channels are regarding as the same, distinguished from the other sedimentary microfacies by Bayesian model created by SP, RMN and RMG values obtained from the large scale patterns. Finally, according to difference in the RMN-GMG between the two microfacies, the slope of the best fit line of RMN-RMG against depth is used to identify gradually abandoned channels and normal ones. A program to implement the method was developed in C/C++ on C++ Builder platform, which computerizes the sedimentary microfacies analysis with log data and facies ichnography creation. This highly computerized, easy-operating method has been used to analyze the log data of 1 480 wells in the east part of No. 2 south area and 20 wells in No. 1 south area in Daqing Oil Field, and the result was well consistent with that of manual work. The success rate of the procedure in correctly identifying the sedimentary microfacies is 80%, which shows its great potential for use in the exploration of meandering depositional oil fields.%针对测井曲线进行沉积微相分析和渐弃型废弃河道微相计算机自动识别的问题,提出基于Haar小波变换的测井曲线沉积微相和渐弃型废弃河道识别的方法.在该方法中,应用小波分解将测井曲线的信号分解为宏观特征信息、细节信息和噪音信息三部分;将渐弃型废弃河道和普通河道作为同一类,利用Bayes判别分析对经小波变换后得到的SP、RMN、RMG曲线的宏观特征信息建立其判相模型,通过该模型将渐弃型废弃河道和普通河道与其他沉积微相进行分离;利用渐弃型废弃河道和普通河道沉积微相在微电

  2. Unskilled Work and Learner Identity

    Kondrup, Sissel

    2014-01-01

    The paper examines how unskilled work forms conditions for meeting the obligation to position oneself as an educable subject and engage in formal learning activities. Sensitivity to peoples’ work-life-experiences is necessary to understand their orientation toward different learning activities....... The main argument is that participation research must abandon the notion of motivation as an individual attribute and apply a dialectic concept of learner identity acknowledging work-life as a pivotal space for learning and formation of identity. I outline how a work-life-historical approach combining...

  3. Long-term ecological behaviour of abandoned uranium mill tailings

    Semi-aquatic and terrestrial areas on abandoned or inactive uranium mill tailings in Ontario were studied in order to identify the growth characteristics of the naturally invading species dominating these areas. Semi-aquatic areas of tailings sites have been invaded by cattails. These species formed wetland communities which varied in size, but all were essentially monocultures of Typha latifolia, T. angustifolia, or of the hybrids T. glauca. Sedges, Scripus cyperinus (wool-grass) and Phragmites australis (reed-grass), were found in transition zones between the cattail stand and the dry section of the tailings site. The expansion of the cattail stands appeared to be controlled by the hydrological conditions on the site, rather than the chemical characteristics of the tailings

  4. Should fine needle aspiration cytology in breast assessment be abandoned?

    Litherland, Janet C

    2002-02-01

    Fine needle aspiration cytology (FNAC) has been used extensively in the U.K. for the diagnosis of breast lesions over the past 15 years. More recently, large gauge needle biopsy has been used to address many of the problems which have been encountered with fine needle aspiration. This paper reviews the evolution of the use of these procedures and the advantages and disadvantages of each. In considering whether to abandon the use of fine needle aspiration cytology in breast assessment, each individual unit should make a decision based upon their own audited results. However, even if FNAC is retained, it is important to be able to complement cytological diagnosis with core biopsy as there are indisputable advantages, e.g. in the diagnosis of mammographically detected microcalcification. As always, a multi-disciplinary approach is ultimately essential for effective patient management. Litherland, J.C. (2002)

  6. Childhood lead poisoning: the promise and abandonment of primary prevention.

    Needleman, H L

    1998-12-01

    In 1991, the Public Health Service published the Strategic Plan for the Elimination of Childhood Lead Poisoning. This document marked a fundamental shift in federal policy from finding and treating lead-poisoned children to authentic primary prevention. It spelled out a 15-year strategy to achieve this goal and provided a cost-benefit analysis showing that the monetized benefits far exceeded the costs of abatement. A strong national effort to eliminate the disease developed. Now, 7 years after publication of the plan, primary prevention of lead exposure has been abandoned. This article examines the role of some prevailing attitudes and institutions in derailing the effort. Some institutions--the lead industry, real estate interests, and insurance interests--behaved as anticipated. Others, including private pediatricians, the American Academy of Pediatrics, some federal agencies, and a public interest group ostensibly dedicated to eliminating lead poisoning, also played an unexpected part in derailing the plan.

    2006-01-01

    Rapid increase in the production of marine shrimps in the coastal zone has resulted in large - scale conversion of mangrove forests to shrimp ponds. Productions of the shrimps in some regions have been unstable. Consequently, a number of ponds are left idle. Restoring environmental conditions within the pond site by planting a suitable mangrove species considered an option. The experiment herein was carried out to explore the effect of planting methods on growth of Nipa palm in abandoned shrimp ponds in the Southern Thailand. Economically, coastal villagers in this area earn their income from the palm in several ways, the most importantly in Nipa sugar production. Most seedlings were planted on top of furrows were constructed in the pond to avoid flooding, except for some seedlings which were planted in the pond base where additional pond sludge were slightly filled up to compare their growth rates. The results showed that planting seedlings with attached rhizomes had the best growth rate and without seedling death at 14 months after planting. At this stage, however, the height of seedlings grown from the fallen fruits was similar to those growth from bare rooted seedlings (70 cm tall). Also, seedling mortality was not observed when growth from fallen fruits whereas about6% mortality was experienced by the bare rooted ones. Among the bare rooted seedling treatments, however no significant differences in growth rates were found when applying the soil with chemical fertilizers or farm manure or liming with CaCO3. In addition, it was found that seedling growth measured at 40 months after planting for those growths in pond base was almost 100% greater than those grown on the furrows. Therefore, this finding may be applied for the restoration of abandoned shrimp ponds by growing Nipa palm.

  9. Restoration of abandoned mine lands through cooperative coal resource evaluations

    The public reclamation cost of reclaiming all of Pennsylvania's abandoned mine lands is estimated at $15 billion. Drainage from abandoned mines poses another $5 billion water pollution clean-up problem. Although it is unlikely that public reclamation alone could ever tackle these problems, much can be done to alleviate the nuisances through the remining of previously mined areas to recover remaining reserves, restore the land and improve water quality in the same process. Remining of priority areas is encouraged through a new Pennsylvania policy which provides incentives to mining companies. One incentive, initiated under Pennsylvania's comprehensive mine reclamation strategy, is to identify and geologically map reminable coal resources in selected watersheds, and then to expedite mine permitting in these watersheds. At present, two such priority watersheds, Little Toby Creek in Elk County and Tangascootak Creek in Clinton County, are the focus of geologic map compilation based on recent quadrangle mapping, or new, directed, geologic mapping, including new research core drilling to establish the geologic stratigraphic framework. In order to maximize environmental benefits the comprehensive mine reclamation strategy identifies watersheds which are affected by acid mine drainage (AMD), but that are reasonably capable of restoration, if sufficient coal reserves remain. Pennsylvania's geochemical quality database of rock overburden, in combination with detailed coal resource mapping by the Pennsylvania Geological Survey, and the cooperation of coal companies and leaseholders, is being used by the Department of Environmental Protection (DEP) to identify and design remining projects which will not only allow the recovery of coal resources, but will also improve the water quality through a variety of innovative mining techniques

    1998-12-01

    Utilization of the openings of the abandoned mines could be planned by the principal parameters such as location and geotechnical impact. The local governments have not only to lead the each stage of the utilization project from the very beginning of conceptual design up to the construction stage, but also to promote the project for the development of public purpose. The possible tentative candidates for the utilization of the abandoned mine openings which are supported by the local governments could be summarized as follows. a. The Gahak mine of Kwangmyung, Kyunggi: The mine caverns which have been served as the storage of the pickled fishes, could be reexcavated by taking into consideration the geotechnical parameters for the public use such as: 1) Training center for the youth, 2) Fermentation and storehouse of marine products, 3) Sightseeing resort, 4) Sports and leisure complex, 5) Underground parking lot, 6) Underground shopping mall and chilled room storage, 7) Library, concert hall and museum. b. Hamtae mine of Taebaek, Kangwon: The Hambaek main haulage way and its shaft should be investigated in detail in order to find out a possible use as the underground challenging park of the coal mining operation. c. Mines of Boryung and Hongsung, Chungnam: Lots of mine caverns have been used as the storehouse for the pickled shrimp. However, they have to be promoted to a large scale industries. d. Imgok mine of Kwangju and Palbong mine of Jeongeup, Chunbuk: Mine caverns which have been used as the storehouse of pickles, need a detailed investigation for alternative promotion. e. Yongho mine of Pusan Dalsung mine of Taegu: Both of the mines are located near metropolitan communities. Reconstruction of the old mine caverns of the Yongho mine is highly recommended for a public use. The caverns of the Dalsung mine could be utilized as the storage facilities. Detailed geotechnical survey and sit investigation could be suggested to design the recommended facilities for both

  11. Abandoned Beach Ridges in the Mejillones Peninsula, Northern Chile: Implications for Paleoseismology of Great Subduction Earthquakes.

    del Río, I. A.; Gonzalez, G.; Antinao, J. L.; McDonald, E.; González-Carrasco, J. F.; Shrivastava, M. N.

    2015-12-01

    The Mejillones Peninsula, in northern Chile, shows a well-preserved set of beach ridges parallel to the present coast. These beach ridges can be observed up to 20 km inland and at 200 m above sea level. Previous dating performed in fossils extracted from the oldest beach ridges yielded ages of 400 ka (Victor et al., 2011). However, numerical ages for younger beach ridges have not been determined, therefore a complete time record is not available. InSar data show that the Mejillones Peninsula was uplifted several centimeters during the last two subduction earthquakes (Antofagasta Mw 8.1, 1995 earthquake and the Mw 7.7, 2007 Tocopilla earthquake) occurred in the area (Loveless et al., 2010). A permanent GPS station deployed by CALTECH (http://web.gps.caltech.edu/~jeff/andes/) in this peninsula has measured a coseismic uplift during the 2007 Tocopilla earthquake. This data suggest that the beach ridges were abandoned as a consequence of coseismic uplift during great subduction earthquakes and therefore they represent the long-term record of past earthquakes. In order to prove this hypothesis we excavated five trenches across the beach ridges. Our idea is to look for stratigraphic evidence of the abandonment mechanism and to collect samples for dating the beach ridges using the method of optically stimulated luminescence (OSL). The ages will be used to estimate long-term uplift rate and temporal variation of this rate. By confronting short-term uplift rate provided by GPS data with long-term rate we hope to know what it is the amount of the coseismic slip that remain in the geological record.

  12. Natural regeneration in abandoned fields following intensive agricultural land use in an Atlantic Forest Island, Brazil

    2012-08-01

    Full Text Available The time required to regrowth a forest in degraded areas depends on how the forest is removed and on the type of land use following removal. Natural regeneration was studied in abandoned old fields after intensive agricultural land use in areas originally covered by Brazilian Atlantic Forests of the Anchieta Island, Brazil in order to understand how plant communities reassemble following human disturbances as well as to determine suitable strategies of forest restoration. The fields were classified into three vegetation types according to the dominant plant species in: 1 Miconia albicans (Sw. Triana (Melastomataceae fields, 2 Dicranopteris flexuosa (Schrader Underw. (Gleicheniaceae thickets, and 3 Gleichenella pectinata (Willd. Ching. (Gleicheniaceae thickets. Both composition and structure of natural regeneration were compared among the three dominant vegetation types by establishing randomly three plots of 1 x 3 m in five sites of the island. A gradient in composition and abundance of species in natural regeneration could be observed along vegetation types from Dicranopteris fern thickets to Miconia fields. The gradient did not accurately follow the pattern of spatial distribution of the three dominant vegetation types in the island regarding their proximity of the remnant forests. A complex association of biotic and abiotic factors seems to be affecting the seedling recruitment and establishment in the study plots. The lowest plant regeneration found in Dicranopteris and Gleichenella thickets suggests that the ferns inhibit the recruitment of woody and herbaceous species. Otherwise, we could not distinguish different patterns of tree regeneration among the three vegetation types. Our results showed that forest recovery following severe anthropogenic disturbances is not direct, predictable or even achievable on its own. Appropriated actions and methods such as fern removal, planting ground covers, and enrichment planting with tree species were

  13. Ten Year Evaluation of Carbon Stock in Mangrove Plantation Reforested from an Abandoned Shrimp Pond

    Jirasak Chukwamdee

    2012-06-01

    Full Text Available Forest carbon stocks—both in terms of the standing biomass and the soil organic carbon (OC—were monitored in the mangrove plantation reforested from an abandoned shrimp pond for the 10 years following land excavation. Excavation to a level of 25 cm below the existing ground level increased the inundation time of tidal water from 463 to 7,597 hours per year, resulting in a significant increase of survival/growth rates for planted mangrove species, Rhizophora mucronata (RM and Bruguiera cylindrica (BC, and of carbon stocks as well. RM showed high rates of standing biomass accumulation with 98.7 ton/ha while 28.8 ton/ha for BC was measured over 10 years in the excavated area. In contrast, the unexcavated area showed low rates of biomass accumulation, 1.04 ton/ha for RM and 0.53 ton/ha for BC in the same period. The excavated area recorded a twofold increase of soil OC in the upper 5 cm of the surface soil from 71.8 to 154.8 ton/ha in 10 years, however it decreased to 68.3 ton/ha in the unexcavated area where soil OC is susceptible to decomposition. These results imply that the potential of carbon sinks in reforested land from abandoned areas cannot be developed unless hydraulic conditions are properly recovered. The fast growing species Avicennia marina (AM grew quickly for the first two years after colonization but its growth slowed down afterwards, showing a limited ability of carbon capture.

    Working time concerns the hours of the day and the days of the week that work takes place. Most people have standard working hours between 0800 and 1800 on week days. But work also takes place at non-standard hours in the evening, at night and on weekends. Non-standard working times constitute an important part of the economy and society. Work at non-standard hours may have negative effects on the health and well-being of workers because of tiredness and problems of combining work and private...

    Saiz de Omeñaca, J.; Ereño, I.; Atxabal, K.; Azurmendi, I.

    1993-09-01

    Solid fills arranged in 1-m-thick layers were prepared with stone blocks and pebbles of a drainage bed every 8 m. Runoff gathering in a well and the use of silts and mud lands for bordering and sealing the limestones are the main techniques employed for minimizing unfavorable effects at the Lezama-Leguizamon abandoned open-pit mine. Since there were waste disposal problems in the area, the rate of disposal has made the activity profitable. No significant faults have been detected by control studies, and the objectives are being achieved without problems.

    : (1) The abandoned dregs field for the mountain high - speed railway should occupy the farmland as less as possible, and it should keep far away from the residential area and produce the less traffic interference. (2) The geological survey and protection works should be well done to get rid of the geological disasters like landslide, (3) The filling dreg field should be adopted as much as possible if the condition is allowable because it serves a double. The mountain gully or mountain foot should be selected as the site of the dreg field because it uses less land and is easy for delivery the dreg. The research result can provide the reference to the similar works.

  19. Outdoor and indoor cadmium distributions near an abandoned smelting works and their relations to human exposure

    The relationship of measured or modelled Cd concentrations in soil, house dust and available to plants with human urinary Cd concentrations were assessed in a population living around a Cd/Pb/Zn smelter in the UK. Modelled air concentrations explained 35% of soil Cd variation indicating the smelter contributed to soil Cd loads. Multi-variate analysis confirmed a significant role of biological and life-style factors in determining urinary Cd levels. Significant correlations of urinary Cd with soil, house dust and modelled plant available Cd concentrations were not, however, found. Potential reasons for the absence of clear relationships include limited environmental contact in urban populations; the role of undefined factors in determining exposure; and the limited spatial scope of the survey which did not sample from the full pollution gradient. Further, the absence of any significant relationship indicates that environmental measures provide limited advantage over atmospheric model outputs for first stage human exposure assessment. - Highlights: → Environmental measurements indicate smelter pollution of a surrounding urban area. → Life-style and biology influenced U-Cd more than measured environmental levels. → Limited contact with outdoor environments may limit Cd uptake in urban populations. → Better life-style data could improve the attribution of human Cd exposure routes. → Measured Cd levels provide limited added exposure insight over dispersion models. - Measured and modelled environmental cadmium concentrations provide limited additional explanation of human urinary cadmium concentrations.

    2015-01-01

    Pumped Storage Hydroelectricity (PSH) is a good alternative to increase the efficiency of power plants, which cannot regulate the amount of electricity generated according to the demand (wind, solar or even nuclear power plants). PSH plants, which consist in two reservoirs located at different heights (upper and lower), can store energy during low demand periods (pumping water from the lower to the upper reservoir) and generate electricity during the high demand peaks (falling water from the ...

    In Inner Mongolia, steppe grasslands face desertification or degradation because of human overuse and abandonment after inappropriate agricultural management. The soils in these abandoned croplands exist in heterogeneous environments characterized by widely fluctuating microbial growth. Quantitative polymerase chain reaction analysis of microbial genes encoding proteins involved in the nitrogen cycle was used to study Azotobacter species, nitrifiers, and denitrifiers in the soils from steppe grasslands and croplands abandoned for 2, 6, and 26 years. Except for nitrifying archaea and nitrous oxide-reducing bacteria, the relative genotypic abundance of microbial communities involved in nitrogen metabolism differed by approximately 2- to 10-fold between abandoned cropland and steppe grassland soils. Although nitrogen-cycle gene abundances varied with abandonment time, the abundance patterns of nitrogen-cycle genes separated distinctly into abandoned cropland versus light-grazing steppe grassland, despite the lack of any cultivation for over a quarter-century. Plant biomass and plant diversity exerted a significant effect on the abundance of microbial communities that mediate the nitrogen cycle (P bacteria that mediate the nitrogen cycle in recently abandoned croplands.

    Objective To evaluate the validity of working well-being scale, and provide a quantitative tool for assessment of factors related to young and middle-aged clinician. Methods A total of 250 young and middle-aged clinician aged between 30 and 45 were recruited from three comprehensive hospitals affiliated to Shanghai Jiaotong University School of Medicine by stratified cluster random sampling, and were asked to complete the working well-being scale, including mood experience section and working well-being cognition section. The construct validity of the scale was assessed by principal components analysis and factorial validity analysis. Results There were 246 effective questionnaires, with the effective rate of 98.4%. The Cronbach's alpha coefficient and content validity index ( CVI) of working well-being scale were 0. 872 and 0. 861 respectively. Considering that the scale was composed of mood experience section and working well-being cognition section, principal components analysis was performed in each section separately. Mood experience section was constituted by 2 main factors: positive mood and negative mood. Principal components analysis indicated that the explanation rate of total variance of original factors reached 59. 94% , and the explanation rate of items reached 88. 9% . Cognition section was constituted by eight main factors: pay and welfare, reward and approval, job occupation, career development, colleague, supervisor, working routine, and interpersonal coordination. The explanation rate of total variance of original factors reached 61. 54% , and the explanation rate of items reached 83. 3% .

    During the last 50 years two main forces have driven the fate of Mediterranean landscapes: land abandonment and forest fires (MacDonald et al., 2000; Moreira et al., 2001). Due to the economical changes suffered by the of the Mediterranean countries after the Second World War, the population migrated from the rural to the urban areas, and from South to North Europe. The land abandonment allowed the vegetation to recover and, as a consequence, an increase in forest fire took place. The soils of the abandoned land recovered the vegetation and litter layers, and consequently changes in soil properties have being found. One of these changes is the increase of soil carbon content, which is due both to vegetation recovery and to fire occurrence that increases the ash and pyrogenic carbon content in soils. Twenty plots were selected in the Macizo del Caroig in Eastern Spain on soils developed on limestone. The period of abandonment and the forest fires that had affected each plot were determined by interviews with the owners, farmers and shepherds. In addition, six (three + three) plots were selected as forest (no plough) and cultivated control plots. Each plot was sampled (10 random samples) and the organic carbon content determined. The results show that the cultivated plots have organic matter contents of 1.02 %, and the forest (Quercus ilex sp.) plots reach the highest value: 14.98 %. Within those we found values that range from 2.34 %, in the recently abandoned plots (10 year abandonment), to values of 8.23 % in the 50 year old abandoned fields.The results demonstrate that there is a recovery of the organic carbon in abandoned soils and that the forest fires do no affect this trend. The increase of soil organic matter after abandonment is a result of the recovery of vegetation(Debussche et al., 2001), which is the consequence of the end of the disturbance of forest that have affected the Mediterranean for millennia (Barbero et al., 1990).

    The reduction of the demand on space for settlement and traffic as well as the improvement of cities and rural settlement structures are the most important key questions and challenges of current environmental policy. An intelligent utilisation of the limited resource space is not only related with positive effects of soil protection (Protection of the ''Green Field''). Measures for estate development on industrial, business and settlement fallow grounds contribute to support a long-lasting city development as well to an economic development. In order to improve the re-integration of pre-used land holdings into the real estate business appropriate legal, planning, financial, tax and incentive instruments are required as well as supplemental measures and activity fields like tradable space certification rights, model projects, research incentives, an optimised space management and improved public work. In the frame of this symposium experts report on their experience in the field of space reactivation of large industrial sites and allow for a discussion of their risks, chances and the resulting challenges. A main focus of the conference programme will be the affects of the present European legal guidelines on water and soil protection. (orig.)

    Faced with the difficult situation of global financial crisis and the downturn in the steel industry, trade union organizations should fully implement the trade union functions. From the desire for building a harmonious enterprise and society, they should strive to do well all the work. In particular, the mass organizations should fully take the advantages of having broad mass base and directly facing the masses and workers, and seriously do well ideological and political work. Unions must thoroughly study the new features of ideological and political work and fully play the advantages of ideological and political work;both can help businesses cope with the financial crisis to promote enterprise development, and can serve workers and play the role of trade unions to show the new environment and act of trade union organizations in the new situation.%面对全球金融危机和钢铁行业不景气的困难局面,企业工会组织要全面履行工会职能,从构建和谐企业和和谐社会的愿望出发,努力做好自己的各项工作。特别要充分发挥具有广泛的群众基础、直接面对职工群众等群众组织的优势,认真做好职工思想政治工作。工会要深入研究思想政治工作的新特点,发挥思想政治工作的优势,既能够帮助企业应对金融危机,促进企业发展,又能够服务职工,发挥工会组织的作用,体现工会组织在新形势下的新气象、新作为。

  11. Irritations caused by the abandonment of national spent fuel management

    The announcement of the intended expansion of German-French cooperation in the field of reprocessing and the abandonment soon after of the Wackersdorf reprocessing plant caught the German nuclear community completely by surprise. The range of reactions extended between profound disappointment and concern on the one hand and relief on the other hand and caused satisfaction and feelings of victory in the nuclear opposition camp. After the short period of time since that decision it is possible to attempt to assess in a more relaxed spirit both the intentions and the resultant new situation in the field of reprocessing in the Federal Republic of Germany. This reveals that also the European solution offers advantages worth being taken into account in addition to the arguments, which are still valid, in favor of reprocessing in Germany. Attention should also be drawn to a different strategy, that of prolonged intermediate storage, which is being employed in major countries, but not being considered in the Federal Republic of Germany.

  12. Integrated approach to hazard evaluation of an abandoned oil refinery

    The multiparameter approach to determine the ecological effects of contaminant residues in an abandoned oil refinery site permitted an evaluation of both sensitivity and resilience of responses from the molecular to the population level of organization. The acute and partial chronic toxicity tests of soil and leachates of soil with conventional aquatic organisms scored similar deleterious responses to the same sites as the resident small mammal populations. While there was not a statistically significant correlation between populational, organismal, and molecular level of responses in this study, this was probably due to the inadequacy of the authors current statistical methodology to analyze the interactions. Populational responses appeared to be less sensitive than the molecular or organismal level of effect. Toxicity tests of soil leachates with standard aquatic test organisms may over estimate the potential effects upon resident populations of small mammals. However, the differences may be attributable to the mobility of resident mammals, i.e., avoidance responses to odoriferous areas except for occasional feeding forays. Aromatic and alkyd hydrocarbons appear to be the major contaminant group at most sites but other semi-polar organics, lead, and fluoride were also detected at the most toxic sites

  13. Proceedings of the NOAMI workshop : a workshop to explore perspectives on risk assessment for orphaned and abandoned mines

    This workshop hosted by the National Orphaned/Abandoned Mines Initiative (NOAMI) discussed risk assessment strategies and perspectives for orphaned and abandoned mines in Canada. Different perspectives related to the risk assessment process were considered by participants from local, provincial, federal, and territorial agencies as well as non-governmental, academic, and mining industry organizations. Strategies for effectively communicating with local communities were discussed. New methods of assessing risk related to bioavailability and bioaccessibility were reviewed along with approaches to risk assessment and risk management in relation to the Environmental Management Act. Case studies of risk assessment and remediation projects were presented. The workshop presentations were divided into the following 6 sessions: (1) keynote, (2) opening panel, (3) human health panel, (4) ecological panel, (5) geotechnical-safety risk assessment panel, and (6) case studies and perspectives. The workshop featured 22 presentations, of which 2 have been catalogued separately for inclusion in this database. A report on detailed ecological risk assessment (DERA) in British Columbia prepared by the Science Advisory Board for Contaminated Sites in British Columbia (BC) was included, as well as a final report that summarized presentations given at the workshop. refs., tabs., figs

    1997-02-01

    The paper contains proposals to specify the content of the pre-abandonment notices which UK mine operators will be required to give in the future. The proposals are designed to enhance the Environment Agency`s ability to tackle water pollution from abandoned mines. They set out the precise contents of the notification, which mine operators will have to send to the Agency at least six months in advance of any intended abandonment. The regulations will cover coal and non-coal mines. Estimated compliance costs to business have been drawn up following consultation with the Department of Trade and Industry, the Health and Safety Executive, the Coal Authority and the Environment Agency. The regulations are due in late spring 1998.

  16. Facilities removal working group

    NONE

    1997-03-01

    This working group`s first objective is to identify major economic, technical, and regulatory constraints on operator practices and decisions relevant to offshore facilities removal. Then, the group will try to make recommendations as to regulatory and policy adjustments, additional research, or process improvements and/or technological advances, that may be needed to improve the efficiency and effectiveness of the removal process. The working group will focus primarily on issues dealing with Gulf of Mexico platform abandonments. In order to make the working group sessions as productive as possible, the Facilities Removal Working Group will focus on three topics that address a majority of the concerns and/or constraints relevant to facilities removal. The three areas are: (1) Explosive Severing and its Impact on Marine Life, (2) Pile and Conductor Severing, and (3) Deep Water Abandonments This paper will outline the current state of practice in the offshore industry, identifying current regulations and specific issues encountered when addressing each of the three main topics above. The intent of the paper is to highlight potential issues for panel discussion, not to provide a detailed review of all data relevant to the topic. Before each panel discussion, key speakers will review data and information to facilitate development and discussion of the main issues of each topic. Please refer to the attached agenda for the workshop format, key speakers, presentation topics, and panel participants. The goal of the panel discussions is to identify key issues for each of the three topics above. The working group will also make recommendations on how to proceed on these key issues.

  17. A descriptive and quantitative approach regarding erosion and development of landforms on abandoned mine tailings: New insights and environmental implications from SE Spain

    The San Cristóbal-Perules mining site in Mazarrón in southeast Spain was subjected to about a hundred years of intense mining activity for lead, silver, and zinc. Metallurgical operations (smelting, calcination, gravity concentration) carried out during the late nineteenth century-early twentieth century induced significant land transformation, and the most conspicuous wastes of this period consist of a chaotic piling of 'old' tailing deposits. Later on, during the mid-twentieth century, 'modern' tailings resulting from froth flotation were accumulated filling small valleys; these latter valley-fill tailings rose sequentially according to the upstream construction method, progressively raising the level of the dam during the process. Once abandoned, both types of tailing deposits underwent severe erosion, resulting in a mosaic of erosional and sedimentary landforms developed upon (e.g., gully formation) and within them (e.g., piping). We made an inventory and classification of these landforms. Our study shows the geomorphic work to reestablish a new steady state between the tailings deposits and the local erosive conditions. This scenario implies several hazards related to the extremely high heavy metal contents of these tailings and the geomorphic instability of the deposits. We also quantified the tailings tonnage and erosion that occurred at one of the tailings dams (El Roble). As shown by an oblique aerial photograph taken in 1968, this dam had a terraced topography, whereas in 2013 this morphology had evolved into a badland-type relief with deep parallel gullies. By recognizing and surveying specific, remnant points along the benches and outslopes of the older terraced topography, we were able to build up a first digital elevation model (DEM1) reflecting the initial topography. A second DEM, this time showing the present topography, allowed quantification of erosion via Material Loss = DEM1 - DEM2. This yields an erosion rate (1968-2009) of 151.8 Mg (MT) ha
