    Full Text Available Underground economy, in view of researchers, economists and jurists, is a theoretical complex construct, a phenomenon with profound social and economic reverberations. This study argues multidisciplinary integrative the sociological, psychological and socio-psychological approach of underground economy. The premises of this study are given by methodological individualism and rational choice theory through building in neoclassical version of Homo economicus able to interact in a multidisciplinary and multifaceted manner with the area of social sciences. For the nonce, we submit to analysis an integrative model of Homo Oeconimicus with Homo Sociologicus, aggregated with elements of social psychology. Synergistic effects of this integrative approach consist of the ability to give an answer as relevant on symptoms and forms of deviant behavior and thus to explain the development of underground economy. The finality of this paper, starting from the stated premises, resides in the explanation and analysis of deviant behavior in the framework of the morphology and causality of underground economy. Deviant behavior in the context of our analysis reveals the coherence perspective on the following issues: anatomy and etiology of underground economy (informal and underground activities, illegal labor, tax fraud, etc.; attitude towards rules, society and the state (tax mentality, tax morality, moral conscience; tax compliance or non-compliance (willingness to pay tax liabilities. This paper is intended to constitute a pleading for an interdependent approach, multi-causal and interdisciplinary of underground economy

  9. Safety consideration and economic advantage of a new underground nuclear power plant design

    International Nuclear Information System (INIS)

    Lyczkowski, R.W.; Ching, J.T.

    1979-01-01

    A conceptual design of an underground nuclear power plant is proposed to make undergrounding of nuclear reactors not only environmentally desirable but also economically feasible. Expedient to the underground environment, this design capitalizes on the pressure-containing and radiation filtering characteristics of the new underground boundary conditions. Design emphasis is on the containment of a catastrophic accident - that of a reactor vessel rupture caused by external means. The High Capacity Rapid Energy Dissipation Underground Containment (HiC-REDUCE) system which efficiently contains loss-of-coolant accidents (LOCAs) and small break conditions is described. The end product is a radiation-release-proof plant which, in effect, divorces the public from the safety of the reactor. (Auth.)

    At the 5th Annual Meeting of the ITA in Atlanta, Georgia, on June 15-17, 1979, the General Assembly approved the formation of the Working Group Seismic Effects on Underground Structures. The objectives of this Working Group are to: (1) collect data on earthquake damage to underground facilities throughout the world; (2) collect information on aseismic design procedures used within the various countries; and (3) synthesize the information and disseminate the results to the member nations of ITA. William W. Hakala of the US was designated the Animateur of the Working Group. The Working Group decided on the following sequential course of action to achieve the stated objectives: (1) continue to develop a bibliograhy on damages to underground structures by dynamic forces. This will be an ongoing activity of the Working Group; (2) each country is to develop a summary of case histories of earthquake damage to underground structures. These case histories will be discussed at the next meeting of the Working Group in order to identify those parameters that permit or prevent such damage; (3) the state-of-the-art paper on earthquake damage to underground opening being prepared in the US (John A. Blume and Associates, Engineers) is presently being printed and will then be distributed to the membership for comment. This report will form the basis for the activities described below; (4) the above activities should lead to a textbook - like document that provides a design philosophy for underground structures subjected to seismic forces; (5) the work tasks will suggest needed research to solve the identified problems. At each Working Group meeting the member nation delegates will provide a summary of research progress in their countries. These research needs will be documented, reviewed, revised, and disseminated on an annual basis

    2015-07-01

    Urban underground transportation projects are introduced to address problems of scarce green land and traffic pollution. As construction of urban underground transportation is still in its infancy, there is no definite quantitative measurement on whether the construction is beneficial and what influences it will place on the region in China. This study intends to construct a comprehensive evaluation method for evaluating social, economic and environmental benefits of urban underground transportation projects and proposes the concept, role and principle for evaluation of environmental and economic benefits. It figures out relationship between the environment and factors of city development. It also summarizes three relevant factors, including transportation, biophysics and social economy, and works out indicators to evaluate the influence of urban underground transportation construction. Based on Contingent Valuation Method (CVM), Cost of Illness Approach (CIA), Human Capital Approach (HCA), this paper constructs 13 monetization calculation models for social, economic and environmental benefits in response to seven aspects, namely, reducing noise pollution and air pollution, using land efficiently, improving traffic safety, reducing traffic congestion, saving shipping time and minimizing transportation costs.

  12. Underground disposal of high active waste

    International Nuclear Information System (INIS)

    Engelmann, H.J.

    1982-01-01

    This paper is concerned with the engineering aspects relating to the deep burial of high active waste in stable geological formations. The design of a repository depends upon a number of factors not least of which is the type of rock in which it is to be constructed. High level wastes must be isolated from man's environment for such periods that subsequent release will not result in an unacceptable hazard to human population. Design aspects of repositories are reviewed and conceptual design are present in relation to the geological formations under consideration. Over long time periods the most probable mode of release of radionuclides is through groundwater contacting the waste. The proposed concepts therefore include the use of engineered and natural barriers to delay the eventual release of waterborne radionuclides into mans environment. In all cases the ultimate barrier will be the geological formation. Nevertheless, depending upon the type of host rock, use will be made of various additional engineered barriers to delay water contacting the high level waste for several hundreds of years. During this time the level of radiation and associated heat emitted by the waste, will fall by several orders of magnitude and the rock temperatures within a repository will be returning to ambient. Thereafter the residual activity will mainly arise from the actinides. Containment may be enhanced by surrounding the canisters with materials having high sorption capabilities for many of the radionuclides involved. The depth at which a repository is excavated must be sufficient to ensure that the overburden will withstand changes in environmental conditions. The depth of cover required in different rock types may vary. In clay excavating at depth of up to -250 m appears feasible, while in hard rocks and salts working at depth of up to -1000 m is entirely practicable. (orig./RW)

    The paper describes the mechanism and design of the wireless device for activation of energy absorber for localization of blast energy in underground openings. The statistics shows that the greatest share of accidents with fatal results associate with explosions in coal mines due to aero-methane and/or air-coal media explosion. The other significant problem is terrorist or accidental explosions in underground structures. At present there are different protective systems to reduce the blast energy. One of the main parts of protective Systems is blast Identification and Registration Module. The works conducted at G. Tsulukidze Mining Institute of Georgia enabled to construct the wireless system of explosion detection and mitigation of shock waves. The system is based on the constant control on overpressure. The experimental research continues to fulfill the system based on both threats, on the constant control on overpressure and flame parameters, especially in underground structures and coal mines. Reaching the threshold value of any of those parameters, the system immediately starts the activation. The absorber contains a pyrotechnic device ensuring the discharge of dispersed water. The operational parameters of wireless device and activation mechanisms of pyrotechnic element of shock wave absorber are discussed in the paper.

    2014-11-01

    Full Text Available The article highlights some sources of inequalities in a globalized world which does not only generate positive impact. In the event it is mismanaged, globalization can give life to a mechanism facilitating tax evasion and, in the same time, ensuring for a small group of individuals, a power position not only when negotiating inside a company but also across the political life of a society. Moreover, the most important traits of corruption and underground economy are marked out in relation to the deepening of social inequality in Romania. These negative phenomena are also present due to the malfunctioning of the market, strengthened monopolies, hindered competition and excessive use of asymmetric information. In the current context of an economic and financial crisis, one much linked to trust, phenomena such as corruption, underground economy and tax evasion have become omnipresent, hot topics in both Romania and Europe. This is how the economy is taken over and significant resources of the public budget are missed by the state. The consequences are severe and can lead to incapacity to ensure a decent standard of living and ultimately social peace. A continuous attempt to curb these phenomena could and should be a priority and a method to settle the public financial equilibrium in Europe and in Romania in particular.

  18. Techno-Economic Comparison of Onshore and Offshore Underground Coal Gasification End-Product Competitiveness

    2017-10-01

    Full Text Available Underground Coal Gasification (UCG enables the utilisation of coal reserves that are currently not economically exploitable due to complex geological boundary conditions. Hereby, UCG produces a high-calorific synthesis gas that can be used for generation of electricity, fuels and chemical feedstock. The present study aims to identify economically competitive, site-specific end-use options for onshore and offshore produced UCG synthesis gas, taking into account the capture and storage (CCS and/or utilisation (CCU of resulting CO 2 . Modelling results show that boundary conditions that favour electricity, methanol and ammonia production expose low costs for air separation, high synthesis gas calorific values and H 2 /N 2 shares as well as low CO 2 portions of max. 10%. Hereby, a gasification agent ratio of more than 30% oxygen by volume is not favourable from economic and environmental viewpoints. Compared to the costs of an offshore platform with its technical equipment, offshore drilling costs are negligible. Thus, uncertainties related to parameters influenced by drilling costs are also negligible. In summary, techno-economic process modelling results reveal that scenarios with high CO 2 emissions are the most cost-intensive ones, offshore UCG-CCS/CCU costs are twice as high as the onshore ones, and yet all investigated scenarios except from offshore ammonia production are competitive on the European market.

    An instrumental neutron activation analysis by gamma-ray spectrometry with high resolution and large volume Ge (Li) detectors followed by data processing with an electronic computer was applied to the multielemental analysis to elucidate the chemical qualities of the underground water which has been widely used in the sake brewing industries in Mikage, Uozaki and Nishinomiya districts, called as miyamizu. The evaporated residues of the water samples were subjected to the neutron irradiations in reactor for 1 min at a thermal flux of 1.5 x 10 12 n.cm -2 .sec -1 and for 30 hrs at a thermal flux of 9.3 x 10 11 n.cm -2 .sec -1 or for 5 hrs at a thermal flux of 3.9 x 10 12 n.cm -2 .sec -1 . Thus, 11 elements in the former short irradiation and 38 elements in the latter two kinds of long irradiation can be analyzed. Conventional chemical analysis including atomic absorption method and others are also applied on the same samples, and putting the all results together, some considerations concerning the geochemical meaning of the analytical values are made.

    Full Text Available Analysis of performance of any economy involves the measurement and correlation of threebasic elements: the rate of economic growth, the rate of inflation and unemployment rate. When the rateof growth (rate of real GDP is high, the production of goods and services is growing and thereforeincreasing the number of jobs, decrease unemployment and raise living standards. If the economy is inrecession phase, increasing fiscal pressure to ensure the necessary budgetary funds triggers complexeconomic mechanisms. Rules more strictly is that those who are not able to operate in the normaleconomy to slide towards the underground economy, and this not because he wants to tax evasion, butbecause they simply can not cope with new regulations. It is widely accepted in economic theory andpractice the idea that reliability scale macroeconomic indicators of a country is affected by size ofunderground economy and the various tests made so far on this subject, focusing either on the socialaspect or the economic or moral, or emphasizes the illegal or the edge of legality. This has led to variousstudies in this area do not provide comparable data or provide data to the contrary. Worldwide were putin place, however, some calculation methods provided that applied the same country and same period,the results are rarely consistent, sometimes even in fundamentally different.

    Full Text Available China has a huge demand for energy. Under the present energy structure of rich coal, lean oil, less gas, limited and low-rising rate renewable energy, discussion focus is now on the high-efficient mining of coal as well as its clean-and-low-carbon use. In view of this, based on an analysis of the problems in the coal chemical industry and the present coal utilization ways such as Integrated Gasification Combined Cycle (IGCC, this paper proposes that underground coal gasification (UCG technology is a realistic choice. By virtue of its advantages in many aspects such as safety & environment, integrated use of superior resources, economic feasibility, etc. this technology can serve as the front-end support and guarantee for coal chemical industry and IGCC. Under the present situation, the following proposals were presented to promote the development of this technology. First, R&D of technical products should be strengthened, a comprehensive feasibility study assessment system should be established, and the relevant criteria in the industry should be formulated. Second, precise market positioning of UCG products should be made with much concern on the integrated economic indicators of each product's complete flow scheme, following the principle of “Technical Feasibility First, Economic Optimization Followed”. Third, a perfect operation and management pattern should be established with strict control over high-efficient, environmentally-friendly, safe, harmonious & compact objectives in the whole industry chain. In conclusion, to realize the large-scale UCG commercial production will strongly promote the optimization and innovation of fossil fuels supply-side economics in China.

    Adriana Veronica LITRA

    2016-07-01

    Full Text Available The paper aims at covering issues related to the underground economy, activities that compound this phenomenon, its magnitude in Romania and reported to the European average. Underground economy in Romania consists of undeclared work (2/3 from the total and unreported income; it decreased from 33.6% of GDP in 2003 to 28% in 2014, but remained over EU-28 average with about 10 p.p. Among EU-28 countries, only Bulgaria exceeds the size of the underground economy of Romania. The underground economy is a challenge for the leadership of the state which must act simultaneously to stop illegal activities, and to discourage non-declaration of the legal activities. Corruption favours maintaining the underground economy, delays economic development, obstructs democratic processes and affects justice and the law state.

    CR-39 solid state nuclear track detectors were used to determine the indoor and underground radon activity at three locations in the northern part of Bangladesh. The indoor radon activity at Naogaon was found to be higher than that at Rajshahi and Ruppur. Radon concentration in the mud-built houses at Naogaon was estimated to be ∼ 500 Bq m -3 (14pCi 1 -1 ) which is more than three times the recommended limit. The underground radon emanation at Naogaon was found to be one order of magnitude higher than that at the other two places. (author)

    An increasing number of tower-type boilers have been selected for advanced double reheat power plants, due to the uniform flue gas profile and the smooth steam temperature increase. The tall height and long steam pipelines lengths will however, result in dramatic increases in the difficulty of construction, as well as increased power plant investment cost. Given these factors, a novel partially-underground tower-type boiler design has been proposed in this study, which has nearly half of the boiler embedded underground, thereby significantly reducing the boiler height and steam pipeline lengths. Thermodynamic and economic analyses were quantitatively conducted on a 1000 MW advanced double reheat steam cycle. Results showed that compared to the reference power plant, the power plant with the proposed tower-type boiler design could reduce the net heat rate by 18.3 kJ/kWh and could reduce the cost of electricity (COE) by $0.60/MWh. The study also investigated the effects of price fluctuations on the cost-effectiveness of the reference power plant, for both the conventional and the proposed tower-type boilers designs, and found that the double reheat power plant with the proposed tower-type boiler design would be even more competitive and price-effective when the coal price and the investment costs increase. The research of this paper may provide a promising tower-type boiler design for advanced double reheat power plants with lower construction complexity and better cost-effectiveness. - Highlights: • A partially-underground tower-type boiler in double reheat power plants is proposed. for double reheat power plants is proposed. • Thermodynamic and economic analyses are quantitatively conducted. • Better energetic efficiency and greater economic benefits are achieved. • The impacts of price fluctuations on the economic feasibility are discussed

South Abinsk Station will use hard coal in beds 0.83 to 20 meters thick and contain 38 percent water and 9.4 percent ash. The angle of dip ranges from 60 to 70/sup 0/. The coal averages 330 meters from the surface. Total reserves are 98 million tons; industrial reserves are 58.5 million tons. 4. Stalinsk Station will use a semianthracite containing 12 to 15 percent ash and 7.7 to 12 percent volatile matter. The beds are 0.8 to 8.3 meters thick; the angle of dip ranges from 35 to 75/sup 0/. Total reserves are 287.6 million tons; reserves for gasification are 74.5 million tons. Depth from surface is 290 to 460 meters. 5. South Kuzbass Station will use hard coal that contains 4 to 19 percent ash and 8 to 15 percent volatiles. The beds are from 0.62 to 5.64 meters thick; the angle of dip ranges from 15 to 70/sup 0/. Total reserves are 156.9 million tons; industrial reserves are 105.5 million tons. The basic economic and technical figures for all five stations are listed. Capital investment costs and costs per unit of fuel are compared with those of conventional coal mines.

    While much attention has been devoted to analyzing how the institutional framework and entrepreneurship impact growth, how economic policy and institutional design affect entrepreneurship appears to be much less analyzed. We try to explain cross-country differences in the level of entrepreneurship...... by differences in economic policy and institutional design. Specifically, we use the measures of economic freedom to ask which elements of economic policy making and the institutional framework that are responsible for the supply of entrepreneurship (our data on entrepreneurship are derived from the Global...... Entrepreneurship Monitor). The combination of these two datasets is unique in the literature. We find that the size of government is negatively correlated with entrepreneurial activity but that sound money is positively correlated with entrepreneurial activity.

    This study developed a methodology to assess the socio-economic impact of the presence and collapse of underground limestone quarries. For this we rely on case study evidence from Riemst, a village located in Eastern Belgium and use both secondary and primary data sources. A sinkhole inventory as well as data about the prevention costs provided by the municipality was used. To estimate the recreational values of the quarries, visitor data was obtained from the tourist office of Riemst. Next, two surveys were conducted among inhabitants and four real estate agents and one notary. The direct and indirect damages were assessed using respectively the repair cost and production and real estate value losses. The total yearly direct and indirect damage equals €415000 (±€85000) and more than half of it can be attributed to the depreciation of real estate (€230000). The quarries have recreational, cultural-historical and ecological values and thus generate societal benefits. The yearly recreational value was at least €613000 in 2012 values. The ecological and cultural-historical values augment to €180000 per year (in 2012 values). Further, our study indicates that the gains from filling up the quarries below the houses located above an underground limestone quarry outweigh the costs in the case study area. The net gain from filling up the underground quarry ranges €38700 to €101700 per house. This is only the lower bound of the net gain from filling up these underground quarries since preventive filling makes future collapses less likely so that future direct repair costs will be most likely smaller.

    Research highlights: {yields} Spatio-temporal variations of Sr concentrations and Sr isotopic composition of groundwater were investigated in a karst underground river system. {yields} Agricultural fertilizers and sewage effluents significantly modified the natural Sr isotopic signature of karst groundwater. {yields} Sr in the carbonate aquifers was relatively non-radiogenic, with low Sr concentrations, while anthropogenic Sr correlated with agricultural fertilizers and sewage effluents was relatively radiogenic, with higher Sr concentrations. {yields} {sup 87}Sr/{sup 86}Sr ratios can provide key information for natural and anthropogenic sources in karst groundwater. - Abstract: The Nandong Underground River System (NURS) is located in a typical karst area dominated by agriculture in SE Yunnan Province, China. Groundwater plays an important role in the social and economical development in the area. The effects of human activities (agriculture and sewage effluents) on the Sr isotope geochemistry were investigated in the NURS. Seventy-two representative groundwater samples, which were collected from different aquifers (calcite and dolomite), under varying land-use types, both in summer and winter, showed significant spatial differences and slight seasonal variations in Sr concentrations and {sup 87}Sr/{sup 86}Sr ratios. Agricultural fertilizers and sewage effluents significantly modified the natural {sup 87}Sr/{sup 86}Sr ratios signature of groundwater that was otherwise dominated by water-rock interaction. Three major sources of Sr could be distinguished by {sup 87}Sr/{sup 86}Sr ratios and Sr concentrations in karst groundwater. Two sources of Sr are the Triassic calcite and dolomite aquifers, where waters have low Sr concentrations (0.1-0.2 mg/L) and low {sup 87}Sr/{sup 86}Sr ratios (0.7075-0.7080 and 0.7080-0.7100, respectively); the third source is anthropogenic Sr from agricultural fertilizers and sewage effluents with waters affected having radiogenic {sup 87

    Underground coal gasification (UCG) allows for exploitation of deep-seated coal seams not economically exploitable by conventional coal mining. Aim of the present study is to examine UCG economics based on coal conversion into a synthesis gas to fuel a combined cycle gas turbine power plant (CCGT) with CO2 capture and storage (CCS). Thereto, a techno-economic model is developed for UCG-CCGT-CCS costs of electricity (COE) determination which, considering sitespecific data of a selected target area in Bulgaria, sum up to 72 Euro/MWh in total. To quantify the impact of model constraints on COE, sensitivity analyses are undertaken revealing that varying geological model constraints impact COE with 0.4% to 4%, chemical with 13%, technical with 8% to 17% and market-dependent with 2% to 25%. Besides site-specific boundary conditions, UCG-CCGT-CCS economics depend on resources availability and infrastructural characteristics of the overall energy system. Assessing a model based implementation of UCG-CCGT-CCS and CCS power plants into the Bulgarian energy network revealed that both technologies provide essential and economically competitive options to achieve the EU environmental targets and a complete substitution of gas imports by UCG synthesis gas production.

    In addition to workers in uranium mines, the staff of other underground mines, such as worker in underground phosphate mines, Can be exposed to 222 Rn and its progeny. In this study the individual radon progeny concentrations were measured in three Egyptian underground phosphate mines to estimate the occupational exposure to the workers in those sites. Active techniques are employed to fulfill the objective of measuring individual radon progeny concentrations (C RaA , C RaB and C RaC ). The mean reported values of radon progeny concentrations exceed the action levels recommended by ICRP 65 (1993). Based on the physical properties of attached radon progeny aerosol and physiological parameters for heavy work activity which recommended by ICRP 66 (1994). the deposition fraction for each airway generation was calculated. From the measured individual radon progeny concentrations in these mines and the calculated values of deposition fractions, the surface activity distribution per generation were calculated in human respiratory system (BB and regions). The maximum values of these activities were found in the upper bronchial airway generations. According to the obtained results, some of the corrective actions were recommended in this study

    Common dynamical properties of business cycle fluctuations are studied in a sample of more than 100 countries that represent economic regions from all around the world. We apply the methodology of multivariate singular spectrum analysis (M-SSA) to identify oscillatory modes and to detect whether these modes are shared by clusters of phase- and frequency-locked oscillators. An extension of the M-SSA approach is introduced to help analyze structural changes in the cluster configuration of synchronization. With this novel technique, we are able to identify a common mode of business cycle activity across our sample, and thus point to the existence of a world business cycle. Superimposed on this mode, we further identify several major events that have markedly influenced the landscape of world economic activity in the postwar era.

    Lifetime management of underground pipelines is mandatory for safe hydrocarbon transmission and distribution systems. Reliability analysis is recognized as a powerful decision-making tool for risk-based design and maintenance. Both the residual stresses generated during the manufacturing process and in-service corrosion reduce the ability to resist internal and external loading. In this study, the residual stress distribution in large diameter pipes has been characterized experimentally in order to be coupled with the corrosion model. During the pipe lifetime, residual stress relaxation occurs due to the loss of pipe thickness as material layers are consumed by corrosion. The reliability-based assessment of residual stress effects is applied to underground pipelines under a roadway, with and without active corrosion. It has been found that the residual stress greatly increases the failure probability, especially in the early stage of the pipe lifetime

    The economic consequences of retrievable storage have been investigated by comparing two extreme options of retrievable storage. In one option the storage facility is kept in operation using minimal backfill of the storage galleries. In the other option the storage facility is completely backfilled, sealed and abandoned. In the second option construction of a new mine will be necessary in case of retrieval. The point in time has been determined when the second option will be cheaper than the first. This has been done for clay, granite and rock salt as host formation, and both for vitrified waste and spent fuel. (authors)

    During the last few years rapid steps have been taken towards drilling for oil in the western Mediterranean sea. Since most of the countries in the region benefit mainly from tourism and considering that the Mediterranean is a closed sea only replenishing its water once every ninety years careful measures are being taken to ensure safe drilling. In that concept this research work attempts to derive a three dimensional model of the seismically active parts of the underlying underground faults in areas of petroleum interest. For that purpose seismic spatio-temporal clustering has been applied to seismic data to identify potential distinct seismic regions in the area of interest. Results have been coalesced with two dimensional maps of underground faults from past surveys and seismic epicentres, having followed careful reallocation processing, have been used to provide information regarding the vertical extent of multiple underground faults in the region of interest. The end product is a three dimensional map of the possible underground location and extent of the seismically active parts of underground faults.

    Manuel Luís Tender

    Full Text Available Abstract Tunnelling has been used for several purposes for thousands of years. In the coming years the world's population will increase in the urban areas. So, the urban centres will have to adapt, in order to guarantee that their future population will have the necessary and sustainable growth. Due to the constraints for surface construction, also connected to environmental issues, this population growth will imply a greater use of the underground. With this optimal growth, the population of the cities will have better mobility, quality of life, and economic and social sustainability. In a first phase, this report will present a historic approach to tunnelling and its foreseeable future. Afterwards, we will present some considerations on the three factors which tunnelling impacts: mobility, quality of life and social sustainability. As a case study, we will analyse the 2nd phase of the construction of the Marão Tunnel (TDM - the longest ever built in the Iberian Peninsula- and describe the options made regarding each of those factors. In this case study, the options implemented made it possible to successfully execute the works. For the industry, this work is important because it describes a successful management of the aspects under analysis.

    Aerosol and activity distributions of 218 Polonium, 214 Lead, 214 Bismuth, and 212 Lead were determined in two different underground mining environments by means of an optimized time-delay counting scheme and diffusion batteries. In one environment, diesel equipment was operating; and in the other, electrically powered equipment. The two environments differed significantly in total aerosol concentration. In the diesel environment, in particular, aerosol concentrations were unsteady, and fluctuated with vehicular traffic and mining activities. As measured by radon progeny disequilibrium, the age of the air ranged from about 25 to 60 minutes. Thoron working levels were of the same order as radon working levels. In this paper, comparisons are made between the aerosol and activity size distributions in both the diesel and electric mine

    In November 1999 Andra began building an Underground Research Laboratory (URL) on the border of the Meuse and Haute-Marne departments in eastern France. The research activities of the URL are dedicated to reversible, deep geological disposal of high-activity, long-lived radioactive wastes in an argillaceous host rock. The studies covered four complementary aspects: acquisition of data (waste packages, material behaviour and clay medium), repository design and reversibility studies, analysis of the long term behaviour of the repository, safety analyses. For the next phase starting in 2007, Andra will carry out integrated tests of a technological scope, i.e. trial drift, demonstrator of current drift. The results should make it possible to assess the safety of a disposal over several tens and even hundreds of thousands of years and submit in 2015 a file for permission request for the HLW and ILW deep disposal.

    To characterize economic development and diagnose the economic health condition, several popular indices such as gross domestic product (GDP), industrial structure and income growth are widely applied. However, computing these indices based on traditional economic census is usually costly and resources consuming, and more importantly, following a long time delay. In this paper, we analyzed nearly 200 million users' activities for four consecutive years in the largest social network (Sina Microblog) in China, aiming at exploring latent relationships between the online social activities and local economic status. Results indicate that online social activity has a strong correlation with local economic development and industrial structure, and more interestingly, allows revealing the macro-economic structure instantaneously with nearly no cost. Beyond, this work also provides a new venue to identify risky signal in local economic structure.

    The subsurface radioactive disposal site located at the Idaho National Engineering and Environmental Laboratory contains neutron-activated metals from nonfuel nuclear-reactor- core components. A long-term corrosion test is being conducted to obtain site-specific corrosion rates to support efforts to more accurately estimate the transfer of activated elements in an arid vadose zone environment. The tests use nonradioactive metal coupons representing the prominent neutron-activated material buried at the disposal location, namely, Type 304L stainless steel, Type 315L stainless steel, nickel-chromium alloy (UNS NO7718), beryllium, aluminum 6061-T6, and a zirconium alloy, (UNS R60804). In addition, carbon steel (the material presently used in the cask disposal liners and other disposal containers) and a duplex stainless steel (UNS S32550) (the proposed material for the high- integrity disposal containers) are also included in the test program. This paper briefly describes the test program and presents the early corrosion rate results after 1 year and 3 years of underground exposure

  13. Economic policy uncertainty index and economic activity: what causes what?

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available This paper is a follow-up on the Economic Policy Uncertainty (EPU index, developed in 2011 by Baker, Bloom, and Davis. The principal idea of the EPU index is to quantify the level of uncertainty in an economic system, based on three separate pillars: news media, number of federal tax code provisions expiring in the following years, and disagreement amongst professional forecasters on future tendencies of relevant macroeconomic variables. Although the original EPU index was designed and published for the US economy, it had instantly caught the attention of numerous academics and was rapidly introduced in 15 countries worldwide. Extensive academic debate has been triggered on the importance of economic uncertainty relating to the intensity and persistence of the recent crisis. Despite the intensive (mostly politically-motivated debate, formal scientific confirmation of causality running from the EPU index to economic activity has not followed. Moreover, empirical literature has completely failed to conduct formal econometric testing of the Granger causality between the two mentioned phenomena. This paper provides an estimation of the Toda-Yamamoto causality test between the EPU index and economic activity in the USA and several European countries. The results do not provide a general conclusion: causality seems to run in both directions only for the USA, while only in one direction for France and Germany. Having taken into account the Great Recession of 2008, the main result does not change, therefore casting doubt on the index methodology and overall media bias.

    Lawrence Livermore National Laboratory, in collaboration with University of California at Berkeley and Lawrence Berkeley Laboratory, is conducting the Dynamic Underground Stripping Project (DUSP), an integrated project demonstrating the use of active thermal techniques to remove subsurface organic contamination. Complementary techniques address a number of environmental restoration problems: (1) steam flood strips organic contaminants from permeable zones, (2) electrical heating drives contaminants from less permeable zones into the more permeable zones from which they can be extracted, and (3) geophysical monitoring tracks and images the progress of the thermal fronts, providing feedback and control of the active processes. The first DUSP phase involved combined steam injection and vapor extraction in a ''clean'' site in the Livermore Valley consisting of unconsolidated alluvial interbeds of clays, sands and gravels. Steam passed rapidly through a high-permeability gravel unit, where in situ temperatures reached 117 degree C. An integrated program of geophysical monitoring was carried out at the Clean Site. We performed electrical resistance tomography (ERT), seismic tomography (crossborehole), induction tomography, passive seismic monitoring, a variety of different temperature measurement techniques and conventional geophysical well logging

    The 2014 Ebola virus disease (EVD) outbreak in the neighbouring West African countries of Guinea, Liberia and Sierra Leone represents the most significant setback to the region's development in over a decade. This study provides evidence on the extent to which economic activity declined and jobs disappeared in Liberia during the outbreak. To estimate how the level of activity and number of jobs in a given set of firms changed during the outbreak, we use a unique panel data set of registered firms surveyed by the business-development non-profit organisation, Building Markets. We also compare the change in economic activity during the outbreak, across regions of the country that had more versus fewer Ebola cases in a difference-in-differences approach. We find a large decrease in economic activity and jobs in all of Liberia during the Ebola outbreak, and an especially large decline in Monrovia. Outside of Monrovia, the restaurants, and food and beverages sectors have suffered the most among the surveyed sectors, and in Monrovia, the construction and restaurant sectors have shed the most employees, while the food and beverages sectors experienced the largest drop in new contracts. We find little association between the incidence of Ebola cases and declines in economic activity outside of Monrovia. If the large decline in economic activity that occurred during the Ebola outbreak persists, a focus on economic recovery may need to be added to the efforts to rebuild and support the healthcare system in order for Liberia to regain its footing.

    2015-04-01

    Full Text Available In the present article we propose to analyze and deepen significant categories of costs funded from the local budgets, namely the expenditure for economic activities. Our scientific approach begins with determining the place occupied by such expenses in local public expenditure by specifying their content and role. The center of gravity of the study is to treat and deepen the three subgroups of expenses that we consider representative: "The expenses for production, transportation, distribution and supply of heat in a centralized system", "Transport Costs" and Expenditure for agriculture and forestry ". The reaserch is based on the quantitative analysis of the expenses for economic actions, in local budgets, based on the existing data from the Statistical Yearbook of Romania, and highlights the structure of this type of expenses as well as the place they hold in the expediture of local budgets.The study includes an analysis of the dynamics of the share held by economic costs within total expenses from local budgets. From the reaserch carried out, it is shown that the evolution and structure of the expenditures for economic actions from local budgets is determined by the action of certain economical and social factors that vary from one administrative teritorial unit to another: the ray of economical develpoment of the administrative ter itorial unit, urbanization, the number and social structure of the population. The reaserch shows that in the field of expenses for economic actions, the largest share is held by expenditures for transportation (almost 80%, far away from the expenses for fuel and energy (13,66%. During the 1999-2013 the dynamic of expenses for economical actions in the total of expenditures of local budgets, is sinusoidal due to the intervention of certain legislative changes.

  9. New SRDN-3 probes with a semi-conductor detector for measuring radon activity concentration in underground spaces

    Przylibski, T.A.; Lidia Fijalkowska-Lichwa; Elzbieta Kochowska; Krzysztof Kozak; Jadwiga Mazur

    2010-01-01

    The article presents new Polish probes SRDN-3, developed at the Institute of Nuclear Chemistry and Technology in Warsaw, equipped with a semi-conductor detector used for continuous measurements of 222 Rn activity concentration. Due to a relatively high lower detection limit, the device is dedicated for use in underground spaces-caves, adits, mines, tourist routes in strongholds, pyramids, etc. Its structure allows for difficult conditions in which the device is transported to the measurement site, as well as hard operating conditions caused chiefly by large ambient relative humidity, reaching up to 100%. The authors present calibration results of these appliances, as well as the results of their work in a cave and an adit in the Sudetes (SW Poland). After almost 2 years of working in difficult conditions, the probes displayed high reliability. No defects of the semi-conductor detectors or the electronics were observed, which ensured problem-free communication of the probe-programmer-PC set. Thanks to this, the authors have a 2 year stock of data, recorded hourly by five probes, at their disposal. The only element that did not withstand the test of extreme operating conditions was one of the combined relative humidity and temperature sensors. No powering problems were observed either, and the batteries were replaced once a year, before the winter season. Also the programmer functioned faultlessly, enabling data transmission to a PC, which, being much more sensitive to operating conditions, had been placed away from the site of probe exposure. After using more sensitive temperature, relative humidity and pressure sensors, SRDN-3 probes will certainly prove an excellent tool for microclimate measurements (including measurement of air-atmosphere exchange) in caves and other underground sites. Even nowadays they are already a satisfactory tool for monitoring 222 Rn concentration in underground spaces. (author)

    Budny, Christoph; Madlener, Reinhard; Hilgers, Christoph

    2015-01-01

    Highlights: • Study of cost effectiveness of power-to-gas and storage of H 2 and renewable methane. • NPV analysis and Monte Carlo simulation to address fuel and electricity price risks. • Gas sale is compared with power and gas market arbitrage and balancing market gains. • Power-to-gas for linking the balancing markets for power and gas is not profitable. • Pipe storage is the preferred option for temporal arbitrage and balancing energy. - Abstract: This paper investigates the economic feasibility of power-to-gas (P2G) systems and gas storage options for both hydrogen and renewable methane. The study is based on a techno-economic model in which the net present value (NPV) method and Monte Carlo simulation of risks and price forward curves for the electricity and the gas market are used. We study three investment cases: a Base Case where the gas is directly sold in the market, a Storage & Arbitrage Case where temporal arbitrage opportunities between the electricity and the gas market are exploited, and a Storage & Balancing Case where the balancing markets (secondary reserve market for electricity, external balancing market for natural gas) are addressed. The optimal type and size of different centralized and decentralized storage facilities are determined and compared with each other. In a detailed sensitivity and cost analysis, we identify the key factors which could potentially improve the economic viability of the technological concepts assessed. We find that the P2G system used for bridging the balancing markets for power and gas cannot be operated profitably. For both, temporal arbitrage and balancing energy, pipe storage is preferred. Relatively high feed-in tariffs (100 € MW −1 for hydrogen, 130 € MW −1 for methane) are required to render pipe storage for P2G economically viable

  19. Short-term 222Rn activity concentration changes in underground spaces with limited air exchange with the atmosphere

    Science.gov (United States)

    Fijałkowska-Lichwa, L.; Przylibski, T. A.

    2011-04-01

    The authors investigated short-time changes in 222Rn activity concentration occurring yearly in two underground tourist facilities with limited air exchange with the atmosphere. One of them is Niedźwiedzia (Bear) Cave in Kletno, Poland - a natural space equipped with locks ensuring isolation from the atmosphere. The other site is Fluorite Adit in Kletno, a section of a disused uranium mine. This adit is equipped with a mechanical ventilation system, operated periodically outside the opening times (at night). Both sites are situated within the same metamorphic rock complex, at similar altitudes, about 2 km apart. The measurements conducted revealed spring and autumn occurrence of convective air movements. In Bear Cave, this process causes a reduction in 222Rn activity concentration in the daytime, i.e. when tourists, guides and other staff are present in the cave. From the point of view of radiation protection, this is the best situation. For the rest of the year, daily concentrations of 222Rn activity in the cave are very stable. In Fluorite Adit, on the other hand, significant variations in daily 222Rn activity concentrations are recorded almost all year round. These changes are determined by the periods of activity and inactivity of mechanical ventilation. Unfortunately this is inactive in the daytime, which results in the highest values of 222Rn activity concentration at the times when tourists and staff are present in the adit. Slightly lower concentrations of radon in Fluorite Adit are recorded in the winter season, when convective air movements carry a substantial amount of radon out into the atmosphere. The incorrect usage of mechanical ventilation in Fluorite Adit results in the most unfavourable conditions in terms of radiation protection. The staff working in that facility are exposed practically throughout the year to the highest 222Rn activity concentrations, both at work (in the adit) and at home (outside their working hours). Therefore, not very well

  20. Techno-economic assessment of hydrogen production from underground coal gasification (UCG) in Western Canada with carbon capture and sequestration (CCS) for upgrading bitumen from oil sands

    International Nuclear Information System (INIS)

    Olateju, Babatunde; Kumar, Amit

    2013-01-01

    Highlights: • Development of a techno-economic model for UCG-CCS and SMR-CCS. • Estimation of H 2 production costs with and without CCS for UCG and SMR. • UCG is more economical for H 2 production with CCS. • SMR is more cost efficient for H 2 production without CCS. • Cost competiveness is highly sensitive to the IRR differential between UCG and SMR. - Abstract: This paper examines the techno-economic viability of hydrogen production from underground coal gasification (UCG) in Western Canada, for the servicing of the oil sands bitumen upgrading industry. Hydrogen production for bitumen upgrading is predominantly achieved via steam methane reforming (SMR); which involves significant greenhouse gas (GHG) emissions along with considerable feedstock (natural gas) cost volatility. UCG is a formidable candidate for cost-competitive environmentally sustainable hydrogen production; given its negligible feedstock cost, the enormity of deep coal reserves in Western Canada and the favourable CO 2 sequestration characteristics of potential UCG sites in the Western Canadian sedimentary basin (WCSB). Techno-economic models were developed for UCG and SMR with and without CCS, to estimate the cost of hydrogen production including delivery to a bitumen upgrader. In this paper, at base case conditions, a 5% internal rate of return (IRR) differential between UCG and SMR was considered so as to account for the increased investment risk associated with UCG. The cost of UCG hydrogen production without CCS is estimated to be $1.78/kg of H 2 . With CCS, this increases to range of $2.11–$2.70/kg of H 2 , depending on the distance of the site for CO 2 sequestration from the UCG plant. The SMR hydrogen production cost without CCS is estimated to be $1.73/kg of H 2 . In similar fashion to UCG, this rises to a range of $2.14 to $2.41/kg of H 2 with the consideration of CCS. Lastly, for hydrogen production without CCS, UCG has a superior cost competitiveness in comparison to SMR

    1965-06-10

    A procedure is described for making an underground storage cavity in a soluble formation. Two holes are drilled, and fluid is pumped into the first hole. This fluid is a non-solute for the formation material. Then pressure is applied to the fluid until the formation is fractured in the direction of the second hole. More non-solute fluid is injected to complete the fracture between the 2 holes. A solute fluid is then circulated between the 2 holes, which results in removal of that part of the formation next to the fracture and the forming of a chamber.

    2017-01-01

    Slate is one of the most important natural materials in Spain, with a potent extractive and processing industry concentrated in the autonomous communities of Galicia, Castile and León. Thanks to its resistance to external agents, its impermeability and its excellent cleavability, slate is used as for roofing and tiling. Almost all the active exploitations in our country where this resource is extracted are open pit mines, where the exploitation ratios have nearly reached their economic limit, making it necessary to look for alternatives that will allow the mining works to be continued. Underground mining is a solution that offers low exploitation ratios, with low spoil generation. The room-and-pillar method with barrier pillars is usually applied for the exploitation of slate deposits. There are several factors to be taken into account when designing a mine (economic, logistical, geotechnical, technical, environmental…), especially for an underground mine. This study focuses on the geotechnical design process of a room-and-pillar underground mine, based on the tributary area theory, the analysis of the tensions in the ground with numerical methods and the choice of an appropriate reinforcement in view of the expected instabilities. This explanation is completed with an example of a design that includes the estimate exploitation rates and production. [es

  7. Underground coal gasification with extended CO2 utilization as economic and carbon neutral approach to address energy and fertilizer supply shortages in Bangladesh

    Nakaten, Natalie; Islam, Rafiqul; Kempka, Thomas

    2014-05-01

    The application of underground coal gasification (UCG) with proven carbon mitigation techniques may provide a carbon neutral approach to tackle electricity and fertilizer supply shortages in Bangladesh. UCG facilitates the utilization of deep-seated coal seams, not economically exploitable by conventional coal mining. The high-calorific synthesis gas produced by UCG can be used for e.g. electricity generation or as chemical raw material for hydrogen, methanol and fertilizer production. Kempka et al. (2010) carried out an integrated assessment of UCG operation, demonstrating that about 19 % of the CO2 produced during UCG may be mitigated by CO2 utilization in fertilizer production. In the present study, we investigated an extension of the UCG system by introducing excess CO2 storage in the gas deposit of the Bahkrabad gas field (40 km east of Dhaka, Bangladesh). This gas field still holds natural gas resources of 12.8 million tons of LNG equivalent, but is close to abandonment due to a low reservoir pressure. Consequently, applying enhanced gas recovery (EGR) by injection of excess carbon dioxide from the coupled UCG-urea process may mitigate carbon emissions and support natural gas production from the Bahkrabad gas field. To carry out an integrated techno-economic assessment of the coupled system, we adapted the techno-economic UCG-CCS model developed by Nakaten et al. (2014) to consider the urea and EGR processes. Reservoir simulations addressing EGR in the Bakhrabad gas field by utilization of excess carbon dioxide from the UCG process were carried out to account for the induced pressure increase in the reservoir, and thus additional gas recovery potentials. The Jamalganj coal field in Northwest Bangladesh provides favorable geological and infrastructural conditions for a UCG operation at coal seam depths of 640 m to 1,158 m. Excess CO2 can be transported via existing pipeline networks to the Bahkrabad gas field (about 300 km distance from the coal deposit) to be

    The method of underground leaching of uranium ores has a number of advantages over extraction followed by processing of the ores in factories. It has been studied in two types of deposit, occurring in rock masses and sandy shales. Research techniques were worked out accordingly for the leaching of uranium from large-grained ore (-200 mm) and from layers in natural stratification. Special models were constructed permitting the simulation of underground leaching conditions. The results obtained were checked in field conditions on experimental plots and experimental underground blocks. The investigations demonstrated the practicability of the process of underground leaching of uranium from certain ores and made it possible to work out flow-sheets and routines for an industrial process, information about which is given in the paper.

    2017-01-01

    Full Text Available The article rated removal efficiency of organic matter in the processes of sorption and sono-sorption of underground water grasped for municipal purposes. The studies were conducted in laboratory scale and verified in pilot scale at the Water Treatment Plant Tarnobrzeg-Jeziórko. In the research used granular activated carbons, ie. WD-Extra, WG-12, Norit Row 0.8 and Filtrasorb 300. The processes efficiency was evaluated on the basis of changes in the following parameters, ie.: total organic carbon (TOC, permanganate index, UV absorbance, turbidity and colour. The ultrasounds were generated by means of disintegrator Sonics&Materials VCX 130, using the sonication time of 1 and 5 minutes. The results obtained for the batch tests allowed to observe a beneficial effect of ultrasound on the efficiency of the removal of organic material in the sorption process. The combination of sonication and sorption on activated carbon increased the efficiency of the removal of organic matter by 6–37% for TOC, and 18.6–27.9% for permanganate index, depending on the sorbent used. The positive laboratory results were not confirmed in a pilot scale. In the flow conditions the sonication process did not affect the efficiency of removal of organic matter on the filter model with a bed of activated carbon.

    The world's largest assessable source of freshwater is hidden underground, but we do not know what is happening to it yet. In many places of the world groundwater is abstracted at unsustainable rates: more water is used than being recharged, leading to decreasing river discharges and declining groundwater levels. It is predicted that for many regions of the world unsustainable water use will increase, due to increasing human water use under changing climate. It would not be long before shortage causes widespread droughts and the first water war begins. Improving our knowledge about our hidden water is the first step to stop this. The world largest aquifers are mapped, but these maps do not mention how much water they contain or how fast water levels decline. If we can add a third dimension to the aquifer maps, so a thickness, and add geohydrological information we can estimate how much water is stored. Also data on groundwater age and how fast it is refilled is needed to predict the impact of human water use and climate change on the groundwater resource.

    He, Yanan; Wang, Shouyang; Lai, Kin Keung

    2010-01-01

    This paper empirically investigates the cointegrating relationship between crude oil prices and global economic activity. The Kilian economic index is used as an indicator of global economic activity. Based on a supply-demand framework and the cointegration theory, we find that real futures prices of crude oil are cointegrated with the Kilian economic index and a trade weighted US dollar index, and crude oil prices are influenced significantly by fluctuations in the Kilian economic index through both long-run equilibrium conditions and short-run impacts. We also develop an empirically stable, data-coherent and single-equation error-correction model (ECM) which has sensible economic properties. Empirical results based on the ECM show that the adjustment implied by a permanent change in the Kilian economic index is a relatively drawn-out process. (author)

    The French concept for geological disposal of high-level radioactive waste is based on a multi-barrier system including metallic containers confined in a clay-stone layer. The main alteration vector is water coming from the host rock and triggering corrosion of metallic components. Despite extreme conditions, microorganisms can adapt and survive in these environments. Anoxic corrosion of metallic containers and water radiolysis produce H{sub 2}, which potentially represents an abundant energetic source for microbial development, especially in this type of environment containing low amounts of biodegradable organic matter. Moreover, formation of Fe(III)-bearing corrosion products such as magnetite (Fe{sub 3}O{sub 4}) can provide electron acceptors for microbial development. Therefore, bio-corrosion studies are needed in order to investigate the activity of hydrogenotrophic bacteria able to reduce sulphates or Fe(III) from iron oxides (passive layer). These studies help in evaluating such microbial impacts on the long-term stability of metallic components involved in radioactive waste disposal. (authors)

    Full Text Available The Underground Economy is a „shadow” of the real economy, endowed with elastic properties: it can be large, small (although not null based on the specifics of a country, its leaders, economic and legal policies. In relation to the real economy, which is monitored by authorities, the underground economy is usually in a state of growth. In this context, methodologically-practical developments for quantitative estimation of unofficial economic activities are of interest. The problem is generated by a lack of a statistical accounting system, a system of economical indicators in the real economy that would serve as basis for a quantitative estimate of indicators pertaining to the underground economy.

    Full Text Available This paper examines the link between health indicators, environmental variables and economic development, and th e consequences of this relationship on economic convergence for a large sample of rich and poor countries. While in economic literature income and environment are seen to have an inverted-U shaped relationship (Environment Kuznets Curve hypothesis, it is also well established that an improvement in environmental quality is positively related to health. Our study focuses on the implications of this relationship for economic convergence. In the early stage of economic development, the gain from income growth could be cancelled or mitigated by environmental degradation through populations' health (and other channels and create a vicious circle in economic activity unlike in developed countries. This in turn could slow down economic convergence. To empirically assess these issues, we proceeded to an econometric analysis through three equations: a growth equation, a health equation and an environment equation. We found that health is a channel through which environment impacts economic growth. When we take into account the effect of environment quality on economic growth, the speed of convergence tends to increase slightly. This shows that environmental quality could be considered as a constraint for economic convergence.

    1988-01-01

    This report presents the results of a technical and economic comparative study of four alternative underground layouts for a nuclear waste geologic repository in salt. The four alternatives considered in this study are (1) separate areas for spent fuel (SF) and commercial high-level waste (CHLW); (2) panel alternation, in which SF and CHLW are emplaced in adjacent panels of rooms; (3) room alternation, in which SF and CHLW are emplaced in adjacent rooms within each panel; and (4) intimate mixture, in which SF and CHLW are emplaced in random order within each storage room. The study concludes that (1) cost is not an important factor; (2) the separate-areas and intimate-mixture alternatives appear, technically, to be more desirable than the other alternatives; and (3) the selection between the separate-areas and intimate mixture alternatives depends upon future resolution of site-specific and reprocessing questions. 5 refs., 6 figs., 12 tabs

  14. Underground disposal of radioactive wastes

    International Nuclear Information System (INIS)

    1981-01-01

    This report is an overview document for the series of IAEA reports dealing with underground waste disposal to be prepared in the next few years. It provides an introduction to the general considerations involved in implementing underground disposal of radioactive wastes. It suggests factors to be taken into account for developing and assessing waste disposal concepts, including the conditioned waste form, the geological containment and possible additional engineered barriers. These guidelines are general so as to cover a broad range of conditions. They are generally applicable to all types of underground disposal, but the emphasis is on disposal in deep geological formations. Some information presented here may require slight modifications when applied to shallow ground disposal or other types of underground disposal. Modifications may also be needed to reflect local conditions. In some specific cases it may be that not all the considerations dealt with in this book are necessary; on the other hand, while most major considerations are believed to be included, they are not meant to be all-inclusive. The book primarily concerns only underground disposal of the wastes from nuclear fuel cycle operations and those which arise from the use of isotopes for medical and research activities

    Desk studies on underground storage of CO{sub 2} were carried out from 1990 to 1991 fiscal years by two organizations under contract with New Energy and Indestrial Technology Development Organization (NEDO). One group put emphasis on application of CO{sub 2} EOR (enhanced oil recovery), and the other covered various aspects of underground storage system. CO{sub 2} EOR is a popular EOR method in U.S. and some oil countries. At present, CO{sub 2} is supplied from natural CO{sub 2} reservoirs. Possible use of CO{sub 2} derived from fixed sources of industries is a main target of the study in order to increase oil recovery and storage CO{sub 2} under ground. The feasibility study of the total system estimates capacity of storage of CO{sub 2} as around 60 Gton CO{sub 2}, if worldwide application are realized. There exist huge volumes of underground aquifers which are not utilized usually because of high salinity. The deep aquifers can contain large amount of CO{sub 2} in form of compressed state, liquefied state or solution to aquifer. A preliminary technical and economical survey on the system suggests favorable results of 320 Gton CO{sub 2} potential. Technical problems are discussed through these studies, and economical aspects are also evaluated.

In particular, the activity of one of the main divisions of the Treasury Bank, which is created and acts as an independent unit, justifies the decision to make certain financial transactions on the relevant financial markets and manages cash flows through interaction with branches, departments and offices of the banking institution. The article also focuses on the problem of the lack of accurate and up-to-date information between the structural units that take part in the management of the finances of the banking institution. In connection with this, it is necessary to create an information and management field of the bank, which is a collection of organized information input and output flows on the financial and economic activities of the bank, forming a unified management information about the financial activities of the banking institution. The article also focuses on the concept of the creation of an informational and managerial tree, according to which, in the structure of management of financial and economic activity of a banking institution, it is necessary to allocate five levels, based on which the principle of obligatory passage of necessary information at all levels with a gradual systematization and generalization. The concept considered in the article gives an idea of the logic and methodology of creating the process of forming general managerial decisions regarding the financial and economic activity of the bank in the future.

    Science.gov (United States)

    Curiel-Esparza, Jorge; Canto-Perello, Julian; Calvo, Maria A

    2004-07-01

    Growth of urban areas, the corresponding increased demand for utility services and the possibility of new types of utility systems are overcrowding near surface underground space with urban utilities. Available subsurface space will continue to diminish to the point where utilidors (utility tunnels) may become inevitable. Establishing future sustainable strategies in urban underground engineering consists of the ability to lessen the use of traditional trenching. There is an increasing interest in utility tunnels for urban areas as a sustainable technique to avoid congestion of the subsurface. One of the principal advantages of utility tunnels is the substantially lower environmental impact compared with common trenches. Implementing these underground facilities is retarded most by the initial cost and management procedures. The habitual procedure is to meet problems as they arise in current practice. The moral imperative of sustainable strategies fails to confront the economic and political conflicts of interest. Municipal engineers should act as a key enabler in urban underground sustainable development.

    Full Text Available Abstract Emerging trends in the use of smartphones, online mapping applications, and social media, in addition to the geo-located data they generate, provide opportunities to trace users’ socio-economic activities in an unprecedentedly granular and direct fashion and have triggered a revolution in empirical research. These vast mobile data offer new perspectives and approaches to measure economic dynamics, and they are broadening the social science and economics fields. In this paper, we explore the potential for using mobile data to measure economic activity in China from a bottom-up view. First, we build indices for gauging employment and consumer trends based on billions of geo-positioning data. Second, we advance the estimation of offline store foot traffic via location search data derived from Baidu Maps, which is then applied to predict Apple’s revenues in China and to accurately detect box-office fraud. Third, we construct consumption indicators to track trends in various service sector industries and verify them with several existing indicators. To the best of our knowledge, this is the first study to measure the world’s second-largest economy by mining such unprecedentedly large-scale and fine-granular spatial-temporal data. In this way, our research provides new approaches and insights into measuring economic activity.

  7. Short-term radon activity concentration changes along the Underground Educational Tourist Route in the Old Uranium Mine in Kletno (Sudety Mts., SW Poland)

    2014-01-01

    Short-term 222 Rn activity concentration changes along the Underground Educational Tourist Route in the Old Uranium Mine in Kletno were studied, based on continuous measurements conducted between 16 May 2008 and 15 May 2010. The results were analysed in the context of numbers of visitors arriving at the facility in particular seasons and the time per day spent inside by staff and visitors. This choice was based on partially published earlier findings (Fijałkowska-Lichwa and Przylibski, 2011). Results for the year 2009 were analysed in depth, because it is the only period of observation covering a full calendar year. The year 2009 was also chosen for detailed analysis of short-term radon concentration changes, because in each period of this year (hour, month, season) fluctuations of noted values were the most visible. Attention has been paid to three crucial issues linked to the occurrence and behaviour of radon and to the radiological protection of workers and visitors at the tourist route in Kletno. The object of study is a complex of workings in a former uranium mine situated within a metamorphic rock complex in the most radon-prone area in Poland. The facility has been equipped with a mechanical ventilation system, which is turned on after the closing time and at the end of the working day for the visitor service staff, i.e. after 6 p.m. Short-term radon activity concentration changes along the Underground Educational Tourist Route in the Old Uranium Mine in Kletno are related to the activity of the facility's mechanical ventilation. Its inactivity in the daytime results in the fact that the highest values of 222 Rn activity concentration are observed at the time when the facility is open to visitors, i.e. between 10 a.m. and 6 p.m. The improper usage of the mechanical ventilation system is responsible for the extremely unfavourable working conditions, which persist in the facility for practically all year.

    Yount, Kathryn M; Zureick-Brown, Sarah; salem, Rania

    2014-06-01

    Intimate partner violence (IPV) against women is widespread, but its implications for their economic and non-economic activities are understudied. Leveraging new data from 564 ever-married women aged 22–65 in rural Minya, Egypt, we estimated logistic regressions and zero-inflated negative binomial regressions to test spillover, compensation, and patriarchal bargaining theories about the influences of women's exposure to IPV on their engagement in and time spent on market, subsistence, domestic, and care work. Supporting compensation theory, exposures to lifetime, recent, and chronic physical or sexual IPV were associated with higher adjusted odds of performing market work in the prior month, and exposures to recent and chronic IPV were associated with higher adjusted odds of performing subsistence work in this period. Supporting compensation and patriarchal bargaining theories, exposures to recent and chronic IPV were associated with more time spent on domestic work in the prior day. Supporting spillover and patriarchal bargaining theories, exposures to lifetime IPV of all forms were associated with lower adjusted odds of performing mostly nonspousal care work in the prior day, and this association was partially mediated by women's generalized anxiety. Women in rural Minya who are exposed to IPV may escalate their housework to fulfill local norms of feminine domesticity while substituting economic activities for nonspousal care work to enhance their economic independence from violent partners.

  15. Politics and economics to shape international oil and gas activity

    1992-01-01

    This paper reports that political and economic events play unusually strong roles in shaping worldwide oil and gas activity levels this year. Developments in the former U.S.S.R. will be critical. As the now-independent republics adopt new economic systems, production and demand patterns will change, as will exports from what has been the world's leading oil producer. Changing conditions in the Middle East among members of the Organization of Petroleum Exporting countries also will affect the industry in the year following the brief Persian Gulf war. Unless worldwide demand surges unexpectedly, these substantial additions to supply will tend to weaken oil prices in 1992

    Abstract Economic decision-making is disrupted in individuals with gambling disorder, an addictive behavior observed in Parkinson’s disease (PD) patients receiving dopaminergic therapy. The subthalamic nucleus (STN) is involved in the inhibition of impulsive behaviors; however, its role in impulse control disorders and addiction is still unclear. Here, we recorded STN local field potentials (LFPs) in PD patients with and without gambling disorder during an economic decision-making task. Reaction times analysis showed that for all patients, the decision whether to risk preceded task onset. We compared then for both groups the STN LFP preceding high- and low-risk economic decisions. We found that risk avoidance in gamblers correlated with larger STN LFP low-frequency (gambling disorder were instead not correlated with pretask STN LFP. Our results suggest that STN activity preceding task onset affects risk decisions by preemptively inhibiting attraction to high but unlikely rewards in favor of a long-term payoff. PMID:29445770

    Using the new data from the OECD-WTO world network of economic activities we construct the Google matrix G of this directed network and perform its detailed analysis. The network contains 58 countries and 37 activity sectors for years 1995 and 2008. The construction of G, based on Markov chain transitions, treats all countries on equal democratic grounds while the contribution of activity sectors is proportional to their exchange monetary volume. The Google matrix analysis allows to obtain reliable ranking of countries and activity sectors and to determine the sensitivity of CheiRank-PageRank commercial balance of countries in respect to price variations and labor cost in various countries. We demonstrate that the developed approach takes into account multiplicity of network links with economy interactions between countries and activity sectors thus being more efficient compared to the usual export-import analysis. The spectrum and eigenstates of G are also analyzed being related to specific activity communities of countries.

    Environmental contamination from leaking underground storage tanks poses a significant threat to human health and the environment. An estimated five to six million underground storage tanks containing hazardous substances or petroleum products are in use in the US. Originally placed underground as a fire prevention measure, these tanks have substantially reduced the damages from stored flammable liquids. However, an estimated 400,000 underground tanks are thought to be leaking now, and many more will begin to leak in the near future. Products released from these leaking tanks can threaten groundwater supplies, damage sewer lines and buried cables, poison crops, and lead to fires and explosions. As required by the Hazardous and Solid Waste Amendments (HSWA), the EPA has been developing a comprehensive regulatory program for underground storage tanks. The EPA proposed three sets of regulations pertaining to underground tanks. The first addressed technical requirements for petroleum and hazardous substance tanks, including new tank performance standards, release detection, release reporting and investigation, corrective action, and tank closure. The second proposed regulation addresses financial responsibility requirements for underground petroleum tanks. The third addressed standards for approval of state tank programs

    The activities feasibility of high temperature underground thermal storage of energy was investigated. Results indicate that salt cavern storage of hot oil is both technically and economically feasible as a method of storing huge quantities of heat at relatively low cost. One particular system identified utilizes a gravel filled cavern leached within a salt dome. Thermal losses are shown to be less than one percent of cyclically transferred heat. A system like this having a 40 MW sub t transfer rate capability and over eight hours of storage capacity is shown to cost about $13.50 per KWh sub t.

    . Established concentrations of 3 H in underground waters of the Karazheera deposit proves the influence of thermo-nuclear explosions and further nuclear tests on underground waters of the deposit ground. Low concentration of 3 H in underground hydrosphere of the deposit is explained by depth of explosions' epicenter (300-500 m), while the waters researched are deposited on the depth of 200 m. But under the lasting deposit pumping, the deep waters polluted under nuclear tests can pull to the deposit. It can cause the pollution of other components of surrounding by radio-active isotopes. Consequently the further research of the Karazheera deposit's underground waters is necessary. Taking into account the unique geo-ecological situation and perspectives of economic developing of SNP, the research has a great scientific and practical importance from the point of working out the ways and preventing measures for negative influence of nuclear tests on objects of environment

    Full Text Available The paper points to the need of thinking about economic activity in modern society in terms of its basic features as a society of global capitalism with many contradictions and their stakeholders in dynamic social structure. In the context of such an approach, an overview to the main phases has been made in the recent history of capitalism (since the 1960th. It has also been pointed to the impact of globalization in promoting money as a driving force of the phase development of capitalism and the consequences of capital virtualization Within those considerations, it is specifically pointed to the connection of globalization and virtualization of capital in shaping the social background, to the creation of economic activity, its social stratification, social inequality and demands for the pursuit of justice and fairness in these conditions, as well as the limiting factors of that realization.

    1979-01-01

    Underground uranium deposits are located by placing wires of dosimeters each about 5 to 18 mg/cm 2 thick underground in a grid pattern. Each dosimeter contains a phosphor which is capable of storing the energy of alpha particles. In each pair one dosimeter is shielded from alpha particles with more than 18 mg/cm 2 thick opaque material but not gamma and beta rays and the other dosimeter is shielded with less than 1 mg/cm 2 thick opaque material to exclude dust. After a period underground the dosimeters are heated which releases the stored energy as light. The amount of light produced from the heavily shielded dosimeter is subtracted from the amount of light produced from the thinly shielded dosimeter to give an indication of the location and quantity of uranium underground

    The soil gas radon content measurements with solid state nuclear track detectors (SSNTDs) are widely used in geoscience, for instance in uranium exploration and earthquake prediction. In these applications the radon frequently is used as a natural tracer of underground fluid transport processes. Obviously, to get the soil radon measuring method more and more effective the study of these transport processes in deeper part of the Earth is fundamental. The Track Detector Group in the Institute of Nuclear Research of the Hungarian Academy of Sciences in Debrecen has been performing environmental radon activity concentration measurements since 1977 with alpha sensitive SSNTDs. These types of measurements were initiated and widely used by the late head of the group Dr. G. Somogyi, who devoted his life to better understanding of the nature. The measurements in caves, springs and drilled wells proved to be effective to study these underground radon transport processes. We are glad to present some results of our investigations. 7 refs, 7 figs

In Seamus Heaney’s The Underground. in the Hungarian Istvan Baka’s Descending to the Underground of Moscow and in Czesław Miłosz’s Orpheus and Eurydice underworld appears as underground, similarly to the contemporary Hungarian János Térey’s play entitled Jeramiah. where underground will also be a metaphorical underworld which is populated with the ghosts of the famous deceased people of Debrecen, and finally, in Péter Kárpáti’s Everywoman the grave of the final scene of the medieval Everyman will be replaced with a contemporary underground station. I analyse how an underground station could be parallel with the underworld and I deal with the role of musicality and sounds in the literary works based on the myth of Orpheus.

    In situ vitrification (ISV), developed by the Pacific Northwest Laboratory (PNL) for the US Department of Energy (DOE), is a thermal treatment process for the remediation of hazardous, radioactive, or mixed waste sites. The process has been broadly patented both domestically and abroad. Since the inception of ISV in 1980, developmental activities have been focused on applications to contaminated soils, and more recently the potential for application to buried wastes and underground structures (tanks). Research performed to date on the more advanced ISV applications (i.e., application to buried wastes and underground tanks) shows that significant technical and economic potential exists for using ISV to treat buried wastes and underground structures containing radionuclides and/or hazardous constituents. Present ISV applications are directed to the treatment of contaminated soils; the likelihood of using ISV to treat underground tanks depends on the resolution of significant technical and institutional issues related to this advanced application. This paper describes the ISV process and summarizes the technical progress of underground tank vitrification (UTV), discusses pertinent regulatory issues facing the use of UTV, and presents the potential cost of UTV relative to other remedial action alternatives

    2014-09-01

    Short-term (222)Rn activity concentration changes along the Underground Educational Tourist Route in the Old Uranium Mine in Kletno were studied, based on continuous measurements conducted between 16 May 2008 and 15 May 2010. The results were analysed in the context of numbers of visitors arriving at the facility in particular seasons and the time per day spent inside by staff and visitors. This choice was based on partially published earlier findings (Fijałkowska-Lichwa and Przylibski, 2011). Results for the year 2009 were analysed in depth, because it is the only period of observation covering a full calendar year. The year 2009 was also chosen for detailed analysis of short-term radon concentration changes, because in each period of this year (hour, month, season) fluctuations of noted values were the most visible. Attention has been paid to three crucial issues linked to the occurrence and behaviour of radon and to the radiological protection of workers and visitors at the tourist route in Kletno. The object of study is a complex of workings in a former uranium mine situated within a metamorphic rock complex in the most radon-prone area in Poland. The facility has been equipped with a mechanical ventilation system, which is turned on after the closing time and at the end of the working day for the visitor service staff, i.e. after 6 p.m. Short-term radon activity concentration changes along the Underground Educational Tourist Route in the Old Uranium Mine in Kletno are related to the activity of the facility's mechanical ventilation. Its inactivity in the daytime results in the fact that the highest values of (222)Rn activity concentration are observed at the time when the facility is open to visitors, i.e. between 10 a.m. and 6 p.m. The improper usage of the mechanical ventilation system is responsible for the extremely unfavourable working conditions, which persist in the facility for practically all year.

    Full Text Available There has been in the recent years an increased preoccupation at international level for the research of the mechanism of development of the underground economy. The numerous vain attempts to measure the dimension of the underground economy persuaded us to embark on a qualitative research of this economic phenomenon. In our investigation on the roots of the underground economy we drew very close to the psychological and sociological aspects of the phenomenon itself. The process of humanizing that has at its origin components of the mimetic principle, like acquisitive mimesis, prompt us to ponder over J.M. Keynes’ words: „The avoidance of taxes is the only intellectual ambition that one feels rewarded for.”

    2017-11-01

    We investigate ancient agricultural terraces and their associated social and economic activities across the site complex consisting of the village at Politiko-Troullia and its more extensive associated taskscape. Surface artifact distributions mapped over 12 ha are integrated with evidence excavated from this Bronze Age settlement in central Cyprus. Contrary to expectations, artifact densities do not diminish with distance from the village architecture. In particular, concentrations of Prehistoric Bronze Age ceramics and ground stone artifacts are most pronounced on nearby terraced hillsides. These terraces were not utilized for domestic structures, but for extensive processing of agricultural crops and copper ore. Bronze Age excavated plant remains indicate cultivation of olives, grapes and figs, with wood resources dominated by olive and pine. Larger, non-portable ground stones and gaming stones are associated with communal social and economic activities in open courtyard settings in Politiko-Troullia. This category of ground stone also is particularly common on the terraced hillsides around Troullia, suggesting that similar behaviors occurred beyond village structures. The terraced landscape of Politiko-Troullia exemplifies a multi-faceted taskscape with a range of agricultural, metallurgical and social activities. Copyright © 2016 Elsevier Ltd.

    Mine Site Technologies (MST) with the support ACARP and Xstrata Coal NSW, as well as assistance from Centennial Coal, has developed a Proximity Detection System to proof of concept stage as per plan. The basic aim of the project was to develop a system to reduce the risk of the people coming into contact with vehicles in an uncontrolled manner (i.e. being 'run over'). The potential to extend the developed technology into other areas, such as controls for vehicle-vehicle collisions and restricting access of vehicle or people into certain zones (e.g. non FLP vehicles into Hazardous Zones/ERZ) was also assessed. The project leveraged off MST's existing Intellectual Property and experience gained with our ImPact TRACKER tagging technology, allowing the development to be fast tracked. The basic concept developed uses active RFID Tags worn by miners underground to be detected by vehicle mounted Readers. These Readers in turn provide outputs that can be used to alert a driver (e.g. by light and/or audible alarm) that a person (Tag) approaching within their vicinity. The prototype/test kit developed proved the concept and technology, the four main components being: Active RFID Tags to send out signals for detection by vehicle mounted receivers; Receiver electronics to detect RFID Tags approaching within the vicinity of the unit to create a long range detection system (60 m to 120 m); A transmitting/exciter device to enable inner detection zone (within 5 m to 20 m); and A software/hardware device to process & log incoming Tags reads and create certain outputs. Tests undertaken in the laboratory and at a number of mine sites, confirmed the technology path taken could form the basis of a reliable Proximity Detection/Alert System.

    Japan Atomic Energy Agency (JAEA) has promoted the Mizunami Underground Research Laboratory (Mizunami URL) as one of generic URL to perform basic research of waste disposal technology for about twenty years. JAEA had carried out consultation activities with local people and community from 1995 when the plan of Mizunami URL opened at the time, because an early approach of JAEA caused a sense of social distrust and concern, which the study area of Mizunami URL would be candidate site of real repository. In this paper, we conducted normative analysis intended for the consultation activities from a viewpoint of procedural justice and distributed justice, used as the social psychological framework in terms of public NIMBY facility. The results show that it is important to develop local partnership, composed of representative local people and organization, at early start in the light of procedural justice and to support deliberation regarding distributive justice and so on by local partnership in the aspect of information and financial administration.

    Climate change is underway and even if mitigation measures are successfully implemented, societies will have to adapt to new climatic conditions in the near future and further. This session had been proposed to gather different studies dedicated to the climate change impact on some human activities, and discuss the possible ways of adaptation. Climate change is often presented in terms of global mean temperature evolutions, but what is important for adaptation concerns the local evolutions, and rather of the variability and extremes than of the mean of the involved meteorological parameters. In the session, studies and applications will be presented, covering different economical and industrial activities, such as energy production, (re-) insurance and risk assessment, water management or tourism.

    Full Text Available Fiscal evasion is mainly found within the underground economy, came to the specialists’ attention within the 1960s, moment in which it took a great extent. The main cause which leads to activities within the underground economy is represented by the increase of direct taxes, which has the largest influence, followed by the intensity of the regulations and the complexity of the fiscal system. The imposed taxes determine more and more countries to act within the underground economy, as long as there is not a proper offer of public goods and infrastructure. In his study, Vito Tanzi indicated as the main cause of the underground economy the level of taxes.(Tanzi,1983:11-15 He adds the instability of the legislative framework, legislative restrictions imposed within certain states, corruption and bureaucracy. Corruption and the activities specific to the underground economy are realities all the states confront with. Gathering information about the dimensions of corruption and the connection with the underground economy proves to be a task which is impossible to achieve, because all the people involved within these mechanisms prefer not to be identified. Even if the underground economy and corruption are considered as being twins, the questions which appear are: who needs them and who fights against them? Theoretically speaking, corruption and the underground economy can be complementary or substitutable.The anticorruption efforts have to focus on a real reform of the administrative system, whereas the citizen’s perception on corruption is mainly based on his personal experiences in direct connection with the state institutions. Both the public sector as well as the private sector should become more responsible, so that the public institutions to be able to carry out their obligations under integrity conditions and without external pressure or implication. Corruption attracts the economic agents to the underground economy, which leads

    Cosmogenic-induced activity is an issue of great concern for many sensitive experiments sited underground. A variety of different arch-type experiments - such as those geared toward the detection of dark matter, neutrinoless double beta decay and solar neutrinos - have reached levels of cleanliness and sensitivity that warrant careful consideration of secondary activity induced by cosmic rays. This paper reviews some of the main issues associated with the modeling of cosmogenic activity underground. Comparison with data, when such data is available, is also presented

    With the deregulation of energy market and the appeal for environment protection, more and more distributed generation (DG) is embedded in the distribution network. However the approach of connecting DG in most cases is based on a so-called ''fit and forget'' policy and the capacity of DG is limited rigidly by distribution network operator (DNO) to avoid the negative effects of high level penetration. Therefore active management (AM) is put forward as an effective method to network reinforcement for the connection and operation of DG. In this paper, the concept and principle of AM are introduced, and several indices are proposed to evaluate both technical and economic impacts of AM on distribution network with DG. To simplify the simulation fuzzy C-means clustering (FCM) algorithm is introduced. The test results on a sample system represent that AM will lead to decrease of power generation of DG, but it can reduce energy losses and improve voltage profile effectively. Furthermore, AM will take great economic incentives to DG developer as well as DNO with reasonable policy. (author)

    In an underground-type nuclear power plant, groups of containing cavities comprising a plurality of containing cavities connected in series laterally by way of partition walls are disposed in parallel underground. Controlled communication tunnels for communicating the containing cavities belonging to a control region to each other, and non-controlled communication tunnels for communicating containing cavities belonging to a non-controlled area to each other are disposed underground. A controlled corridor tunnel and a non-controlled corridor tunnel extended so as to surround the containing cavity groups are disposed underground, and the containing cavities belonging to the controlled area are connected to the controlled corridor tunnel respectively, and the containing cavities belonging to the non-controlled area are connected to the non-controlled corridor tunnel respectively. The excavating amount of earth and sand upon construction can be reduced by disposing the containing cavity groups comprising a plurality of containing cavities connected in series laterally. The time and the cost for the construction can be reduced, and various excellent effects can be provided. (N.H.)

    To examine changes in the use of alcohol, cannabis and hypnotics/sedatives between two periods (before and during Spain's economic crisis), and to identify differences in the change between employed and unemployed individuals. Using cross-sectional data from four editions of the Spanish Household Survey on Alcohol and Drugs, we selected economically active individuals aged 16-64 years (total sample = 62 440) and defined two periods, pre-crisis [period 1 (P1) = 2005-07] and crisis (P2 = 2009-11). Poisson regression models with robust variance were fitted to obtain prevalence ratios (PR) of heavy and binge drinking and multinomial regression models to obtain relative risk ratios (RRR) of cannabis and hypnotic/sedative use between the two periods, also considering the interaction between period and employment status. While the prevalence of alcohol use remained stable, heavy drinking declined in P2 in men both overall [PR = 0.73; 95% confidence interval (CI) = 0.67-0.79] and in the two age groups (16-34 and 35-64 years), and also in women overall (PR = 0.86; 95% CI = 0.75-0.99) and in the older age group. In contrast, binge drinking increased overall in P2 in men (PR = 1.17; 95% CI = 1.12-1.22) and in women (PR = 1.62; 95% CI = 1.49-1.76), and in both age groups. No differences in the change were observed between employed and unemployed individuals. Overall cannabis use remained stable in P2, but unemployed men and women of the older age group were more likely to have increased sporadic use compared to their employed counterparts (RRR = 2.24; 95% CI = 1.36-3.68 and RRR = 3.21; 95% CI = 1.30-7.93, respectively). Hypnotic/sedative use remained stable in P2 in men, but unemployed men were less likely to have increased heavy use in P2 compared with employed men (RRR = 0.69; 95% CI = 0.49-0.97). In women, heavy use increased in P2 overall and in the older age group, irrespective of employment status. During a period of economic recession in Spain, heavy drinking

    Usually, the power of taxation is straightly connected to the idea of territory. It is important to establish the limits of tax jurisdiction not only for taxes in view of which territoriality is part of the taxable event as defined in legislation - import tax (I.I.) and excise tax (IPI) -, but also for those the location of a possession - property tax (IPTU) - or the place in which services are rendered - service occupation tax (ISS) and sales tax (ICMS) - appear as the main component of the taxable event. According to the United Nations Convention on the Law of the Sea, 1982, and the Brazilian internal legislation as well, Federal Government has full sovereignty over its territorial sea -12 mile zone. In other areas (contiguous zone, exclusive economic zone and brazilian continental shelf), sovereignty is restricted to the supervision of some activities, not involving power of taxation. (author)

  12. Changes in economic activity: The role of age and education

    Directory of Open Access Journals (Sweden)

    Full Text Available Background: Between 2000 and 2010, the labor force participation (LFP of European men stayed mostly constant, whereas the participation of women continued to increase. Participation rates of people close to normal retirement ages rose almost universally. At the same time, the education composition shifted toward higher levels of educational attainment and education-specific differentials in economic activity persisted. Objective: The aim of the paper is to understand the extent to which developments of LFP rates between 2000 and 2010 in selected European countries can be explained by age-specific and education-specific changes in participation rates, as compared to changes in populations' structural composition by age and education. Methods: We apply a decomposition methodology that allows us to disentangle changes in age- and education-specific LFP rates from changes in the age and educational structure of the population. Results: Our results show that LFP rates of adult women would have increased even more, had it not been for the downward pressure from the shift in the age composition toward older age groups with relatively lower levels of participation. This downward pressure also depressed male participation. The increase in participation among older people is mainly explained by participation increases among those with nontertiary education and is reinforced by a general shift toward higher levels of educational attainment. Contribution: Beyond changes in the age structure, we quantify the role of compositional changes by educational attainment. Our results indicate that labor supply may not decrease to the extent expected due to population aging, given educational expansion and education-specific patterns of economic activity.

    Although anthropogenic seismic activities so far have not caused damage to persons and property, they have been the cause of highly emotional discussions in the media, and some are even demanding a ban on geothermal heat recovery. This has caused great concern among the public. A fact-based analysis of the fundamentals of these seismic events in the context of other anthropogenic seismic events shows that the potential seismic effects are far less important than other anthropogenic seismic events. Further, it will in all probability be possible to keep them under control even on a long-term basis. (orig.)

  17. Review of underground siting of nuclear power plants

    International Nuclear Information System (INIS)

    1974-01-01

    A review of the potential for the underground siting of nuclear power generating plants has been undertaken. The review comprised a survey and assessment of relevant published documents currently available, together with discussions with Government sponsored agencies and other bodies, to evaluate the current status of technology related to the design and construction of underground nuclear power plants. It includes a review of previous work related to the underground siting of power plants and other facilities; a preliminary evaluation of the relative merits of the various concepts of undergrounding which have been proposed or constructed; a review of current technology as it relates to the requirements for the design, construction and operation of underground nuclear power plants; an examination of the safety and environmental aspects; and the identification of areas of further study which will be required if the underground is to be established as a fully viable alternative to surface siting. No attempt has been made to draw final conclusions at this stage. Nothing has been found to suggest that the underground siting concept could not provide a viable alternative to the surface concept. It is also apparent that no major technological developments are required. It is not clear, however, whether the improvements in safety and containment postulated for the underground can be realized at an economic cost; or even whether any additional cost is in fact involved. The problem is essentially site dependent and requires further study for which recommendations are made. (auth)

    Due to the deep socioeconomic implications, induced seismicity is a timely and increasingly relevant topic of interest for the general public. Cases of induced seismicity have a global distribution and involve a large number of industrial operations, with many documented cases from as far back to the beginning of the twentieth century. However, the sparse and fragmented documentation available makes it difficult to have a clear picture on our understanding of the physical phenomenon and consequently in our ability to mitigate the risk associated with induced seismicity. This review presents a unified and concise summary of the still open questions related to monitoring, discrimination, and management of induced seismicity in the European context and, when possible, provides potential answers. We further discuss selected critical European cases of induced seismicity, which led to the suspension or reduction of the related industrial activities.

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    2010-01-01

    The 2010 edition of 'Underground Gas Storage in the World' provides an update to the previous survey released by CEDIGAZ in 2006. At that time, 610 underground gas storage (UGS) facilities were in operation worldwide, with a working capacity of 319 billion cubic metres (bcm). As of 1 January 2010, this number had reached 642 facilities with a working gas capacity of 333 bcm, or 10.8% of world gas consumption. By 2020, the global UGS demand is expected to grow at a pace of 3.3% per year, and according to the projects identified, more than 760 UGS sites could be active in the world with a total working capacity of approximately 465 bcm. In this survey, CEDIGAZ analyses the following trends which characterise the rapid development of underground gas storage in the world: - the strong dynamics of the European storage market, where 127 projects could add 75 bcm of working capacity by 2020, - the continued development of the UGS market in the United States (49 projects), encouraged by market-based rates allowed by the FERC, and rapid permitting processes, - the development of facilities in countries with little or no storage capacities at present, in Asia/Oceania, the C.I.S., and Eastern Europe in particular. This survey provides an analysis of the recent evolutions in the technic-economic aspects of the underground gas storage business, as well as an overview of the UGS markets and their developments in the world, country by country. A specific section is dedicated to the analysis of future UGS needs in Europe by 2020: - Technic-economic aspects of UGS: This part of the survey analyses the latest technical improvements and research axes in the field of underground gas storage. As it is more difficult to build greenfield storage facilities, a lot of work has been done to improve the performance and flexibility of existing storage sites. This section also deals with the evolution of investment and operational costs in storage over the last few years. Furthermore, the

    Full Text Available Dans le cadre de la recherche des stockages souterrains de gaz, le Département Réservoirs Souterrains de Gaz de France est amené à établir un programme d'exploration destiné à sélectionner définitivement, et au moindre coût, les structures capables de satisfaire la demande. Cette sélection passe par une estimation des probabilités de rejet ou d'abandon affectant les différentes structures susceptibles de donner lieu à une exploration. Il faut ensuite constituer le programme d'exploration de chacun des sites retenus après cet examen; ce programme consiste en une liste d'opérations (forage, sismique, essai hydraulique, forage à faible profondeur etc. qui mettront le plus vite possible en évidence : - d'une part les défauts; - d'autre part les principales caractéristiques techniques de la structure étudiée. La règle est d'atteindre la décision sur la faisabilité du site au stockage avec le moindre coût d'exploration. Pour ce faire, une analyse détaillée des causes potentielles d'abandon (recensement des défauts permet de choisir les opérations à effectuer, et d'associer à chacun des défauts recensés, l'opération ou l'ensemble d'opérations permettant de le détecter de façon certaine. Alors les estimateurs économiques tels que l'espérance de dépense, le risque financier, l'espérance de gain, sont calculés pour chacun des programmes, en vue de déterminer l'ordre d'exécution optimal des opérations. L'intérêt d'une telle approche, en ce qui concerne la réduction des dépenses d'exploration, est illustré par un exemple. As part of its work concerning the search for underground gas storage sites, the Underground Storage Department of Gaz de France has established an exploration program for the definitive and lowcost selection of suitable geological structures. This selection involves estimating probabilities of rejecting or abandoning different structures liable to be targets for exploration. The

  15. Economic activity in agriculture in the perspective of embeddedness theory: The case of Poland

    Directory of Open Access Journals (Sweden)

    Dudek Michał

    2016-01-01

    Full Text Available The paper presents the concept of embeddedness of economic activity in relation to agriculture. In this perspective, economic activity can be considered dependent on cognitive structures, structures of social relations, culture, and political institutions. It has been concluded that the idea of embeddedness can be an interesting and useful analytical tool for the analysis of economic activity undertaken by farmers. The article presents an analysis of the state of the art, as well uses selected information and data on the methodology of panel surveys carried out by the Institute of Agricultural and Food Economics - National Research Institute. Based on the analysis of the embeddedness theory, it is argued that embeddedness is not a coherent theoretical concept but rather a potential framework for investigating various economic issues. One of these issues is agricultural activity. Embeddedness framework constitutes a scheme which could organize an alternative approach to economic actions to mainstream agriculture economics.

    2011-08-01

    The accumulation of tectonic stress may cause earthquakes at some epochs. However, in most cases, it leads to crustal deformations. Underground water level is a sensitive indication of the crustal deformations. We incorporate the information of the underground water level into the stress release models (SRM), and obtain the underground water stress release model (USRM). We apply USRM to the earthquakes occurred at Tangshan region. The analysis shows that the underground water stress release model outperforms both Poisson model and stress release model. Monte Carlo simulation shows that the simulated seismicity by USRM is very close to the real seismicity.

    Newcomer countries expected to develop new nuclear power programs by 2030 are being encouraged by the International Atomic Energy Agency to explore the use of shared facilities for spent fuel storage and geologic disposal. Multinational underground nuclear parks (M-UNPs) are an option for sharing such facilities. Newcomer countries with suitable bedrock conditions could volunteer to host M-UNPs. M-UNPs would include back-end fuel cycle facilities, in open or closed fuel cycle configurations, with sufficient capacity to enable M-UNP host countries to provide for-fee waste management services to partner countries, and to manage waste from the M-UNP power reactors. M-UNP potential advantages include: the option for decades of spent fuel storage; fuel-cycle policy flexibility; increased proliferation resistance; high margin of physical security against attack; and high margin of containment capability in the event of beyond-design-basis accidents, thereby reducing the risk of Fukushima-like radiological contamination of surface lands. A hypothetical M-UNP in crystalline rock with facilities for small modular reactors, spent fuel storage, reprocessing, and geologic disposal is described using a room-and-pillar reference-design cavern. Underground construction cost is judged tractable through use of modern excavation technology and careful site selection. (authors)

    The CASPAR mainly focuses on Stellar Nucleosynthesis, its impact on the production of heavy elements and study the strength of stellar neutron sources that propels the s-process, 13C(α,n)16O and 22Ne(α,n)25Mg. Currently, implementation of a 1MV fully refurbished Van de Graaff accelerator that can provide a high intensity Î+/- beam, is being done at the Sanford Underground Research Facility (SURF). The accelerator is built among a collaboration of South Dakota School of Mines and Technology, University of Notre Dame and Colorado School of Mines. It is understood that cosmic ray neutron background radiation hampers experimental Nucleosynthesis studies, hence the need to go underground in search for a neutron free environment, to study these reactions at low energies is evident. The first beam was produced in the middle of summer 2017. The entire accelerator will be run before the end of this year. A detailed overview of goals of CASPAR will be presented. NFS Grant-1615197.

    1994-01-01

    Underground storage tanks, UST'S, have become a major component of the Louisville District's Environmental Support Program. The District's Geotechnical and Environmental Engineering Branch has spear-headed an innovative effort to streamline the time, effort and expense for removal, replacement, upgrade and associated cleanup of USTs at military and civil work installations. This program, called Yank-A-Tank, creates generic state-wide contracts for removal, remediation, installation and upgrade of storage tanks for which individual delivery orders are written under the basic contract. The idea is to create a ''JOC type'' contract containing all the components of work necessary to remove, reinstall or upgrade an underground or above ground tank. The contract documents contain a set of generic specifications and unit price books in addition to the standard ''boiler plate'' information. Each contract requires conformance to the specific regulations for the state in which it is issued. The contractor's bid consists of a bid factor which in the multiplier used with the prices in the unit price book. The solicitation is issued as a Request for Proposal (RPP) which allows the government to select a contractor based on technical qualification an well as bid factor. Once the basic contract is awarded individual delivery orders addressing specific areas of work are scoped, negotiated and awarded an modifications to the original contract. The delivery orders utilize the prepriced components and the contractor's factor to determine the value of the work

    The disaster prevention and environment technology, which is the essential conditions for the living in the underground space, was developed to be applied to a simulated model space. The basic conditions including the location and utilization for the simulation model are as follows: (1) It locates at the city center of a big city, (2) A station for a high speed rail way (linear car) is located at the deep underground (50 m), (3) As there are still many physiological and psychological problems left unsolved for the living including dinning and sleeping in the underground, such facilities as private residential house, hotel, and hospital were excluded. Such facilities as shop, restaurant, theater, recreation facility, city hall, police station, and parking lot were considered. For the disaster prevention design, the design technique for emergency evacuation system within the building and for the smoke control system were taken up. For the air conditioning design, the large space air conditioning design, energy saving design system, and the deodorant air conditioning system were investigated. The energy program and the aqueduct program were also discussed. 24 figs., 6 tabs.

  17. Fast and safe gas detection from underground coal fire by drone fly over

    International Nuclear Information System (INIS)

    Dunnington, Lucila; Nakagawa, Masami

    2017-01-01

    Underground coal fires start naturally or as a result of human activities. Besides burning away the important non-renewable energy resource and causing financial losses, burning coal seams emit carbon dioxide, carbon monoxide, sulfur oxide and methane, and is a leading cause of smog, acid rain, global warming, and air toxins. In the U.S. alone, the combined cost of coal-fire remediation projects that have been completed, budgeted, or projected by the U.S. Department of the Interior's Office of Surface Mining Remediation and Enforcement (OSM), exceeds $1 billion. It is estimated that these fires generate as much as 3% of the world's annual carbon dioxide emissions and consume as much as 5% of its minable coal. Considering the magnitude of environmental impact and economic loss caused by burning underground coal seams, we have developed a new, safe, reliable surface measurement of coal fire gases to assess the nature of underground coal fires. We use a drone mounted with gas sensors. Drone collected gas concentration data provides a safe alternative for evaluating the rank of a burning coal seam. In this study, a new method of determining coal rank by gas ratios is developed. Coal rank is valuable for defining parameters of a coal seam such as burn temperature, burn rate, and volume of burning seam. - Graphical abstract: Concluding Figure for Gas Ratios: Plotted points and ranges of adjusted literature data. Stars represent bituminous and subbituminous coal types; Ovals represent lignite. - Highlights: • Recognize underground coal fire as a potential source of energy. • Developed a creative, safe, reliable and fast gas detection method. • Developed a concept of gas ratio measurement method that can provide more accurate description of underground burning coal resource.

  20. THE GENERATING AND COMPLEMENTARY EFFECTS OF THE UNDERGROUND ECONOMY PHENOMENON

    Directory of Open Access Journals (Sweden)

    Corneliu Sorin BAICU

    2016-12-01

    Full Text Available For a comprehensive understanding of the informal sector, an analysis addressing the relationships and links between the morphology and etiology of the underground economy, on the one hand, and its effects on the economic, social or legal, on the other hand is required. The double identity, that of cause phenomenon and effect phenomenon, that the underground economy has, gives it a special status in explaining certain phenomena which vitiates the economic and social life. The generating and complementary effects of the underground area covered in this study are analyzed in terms of the following vectors of analysis: tax evasion, illegal work and money laundering. Tax evasion represents the central core of the underground economy and faithfully expresses the fiscal monetary policies ,the fiscal mortality and the degree of compliance of the taxpayer. Undeclared work is an indicator of the labor market in the informal economy and is a good barometer for analyzing the demand and supply of labor in the visible economy. Money laundering defines the level of economic and financial crime and reflects the level of illegal use of capital on the black market. Tax evasion, money laundering and illegal work can only develop on a framework provided by illicit markets for goods, services and labor. Beyond the, unidirectional or bidirectional relationships between phenomena, the paper consists in a plea for an interdependent, multi-causal analysis of the phenomena and operating mechanisms of the relationships within and outside the underground economy.

    1989-01-01

    In the feasibility study for an underground repository in Argentina, the conceptual basis for the final disposal of high activity nuclear waste was set, as well as the biosphere isolation, according to the multiple barrier concept or to the engineering barrier system. As design limit, the container shall act as an engineering barrier, granting the isolation of the radionuclides for approximately 1000 years. The container for reprocessed and vitrified wastes shall have three metallic layers: a stainless steel inner layer, an external one of a metal to be selected and a thick intermediate lead layer preselected due to its good radiological protection and corrosion resistance. Therefore, the study of the lead corrosion behaviour in simulated media of an underground repository becomes necessary. Relevant parameters of the repository system such as temperature, pressure, water flux, variation in salt concentrations and oxidants supply shall be considered. At the same time, a study is necessary on the galvanic effect of lead coupled with different candidate metals for external layer of the container in the same experimental conditions. Also temporal evaluation about the engineering barrier system efficiency is presented in this thesis. It was considered the extrapolated results of corrosion rates and literature data about the other engineering barriers. Taking into account that corrosion is of a generalized type, the integrity of the lead shall be maintained for more than 1000 years and according to temporal evaluation, the multiple barrier concept shall retard the radionuclide dispersion to the biosphere for a period of time between 10 4 and 10 6 years.

    2017-01-01

    It is a disquieting reality that increased economic growth for many years now in the Western world is at odds with environmental degradation. In this paper the relationship between economic growth and environmental variables is analyzed under two non-linear specifications, a quadratic and a cubic specification. The study is conducted for Portugal and Spain in the period 1975–2012, using data for 13 sectors. GVA is used as proxy for income, while energy use and carbon dioxide account for environmental degradation. There is evidence for an inverted U-shaped EKC. However, there are also other inverted N–shaped functions that explain the relationship between economic growth and emissions. Altogether, empirical results do indicate particular differences between Portuguese and Spanish sectors. The results are of interest not only for researchers but also for policy-makers. Political mitigation measures are also analyzed. - Highlights: • We study the EKC hypothesis using economic activity sectors in the Iberian Market. • There is evidence for a clear N-shaped EKC in Portugal. • Inverted N–shaped function explains the economic growth and emissions relationship. • Positive and significant effect of energy consumption in emissions for sectors. • Promote renewables substitution and tax benefits are urgent to accomplish goals.

    1956-11-21

    A paper in Pravda by the Deputy Chief Engineer of the Underground Gasification Department indicates that there are at least three or four pilot plants in operation; one plant near Moscow has operated for 14 years and one in the Donbas for 8 years. The first plant has a daily output of gas corresponding to 400 tons of coal a day and produces a gas of low calorific value. A plant opened in 1956 in the Kuzbas to produce gas of a higher quality. A plant, being built near Moscow in conjunction with a gas turbine electrical power station, will produce gas equivalent in heating value to 220,000 tons of coal a year. A larger plant, being built at Angren in central Asia, will produce gas equivalent in heating value to 700,000 tons of coal a year.

    Full Text Available This paper gives insight into the use of underground space in Helsinki, Finland. The city has an underground master plan (UMP for its whole municipal area, not only for certain parts of the city. Further, the decision-making history of the UMP is described step-by-step. Some examples of underground space use in other cities are also given. The focus of this paper is on the sustainability issues related to urban underground space use, including its contribution to an environmentally sustainable and aesthetically acceptable landscape, anticipated structural longevity and maintaining the opportunity for urban development by future generations. Underground planning enhances overall safety and economy efficiency. The need for underground space use in city areas has grown rapidly since the 21st century; at the same time, the necessity to control construction work has also increased. The UMP of Helsinki reserves designated space for public and private utilities in various underground areas of bedrock over the long term. The plan also provides the framework for managing and controlling the city's underground construction work and allows suitable locations to be allocated for underground facilities. Tampere, the third most populated city in Finland and the biggest inland city in the Nordic countries, is also a good example of a city that is taking steps to utilise underground resources. Oulu, the capital city of northern Finland, has also started to ‘go underground’. An example of the possibility to combine two cities by an 80-km subsea tunnel is also discussed. A new fixed link would generate huge potential for the capital areas of Finland and Estonia to become a real Helsinki-Tallinn twin city.

  10. Underground communications and tracking technology advances

    As the June 2009 deadline set by the MINER Act grows near, several technologies have emerged as possible options for communicating and tracking underground coal miners in the event of an emergency or disaster. NIOSH is currently deciding how best to invest $10 million assigned by Congress under an Emergency Supplementary Appropriations Act (ESA) to research and develop mine safety technology. Medium and ultra high frequency (UHF) systems seem to be leading the pack with radio frequency identification (RFID) tags serving as the tracking system. Wireless mesh systems can serve as a communications infrastructure and they can do much more. Even more technologies continue to emerge, such as inertial navigation tracking systems. Mines are discovering the wonders of modern voice and data communications underground. Still no one know if it is economically practical to design a system that will function after a coal mine explosion. From the nineteen systems submitted to MSHA's request for information (RFI), six systems were selected that represented most of the technologies that had been proposed: the Rajant Breadcrumb, Innovative Wireless, Concurrent Technologies/Time Domain, Transtek, Gamma Services, and the Kutta Consulting systems. They were tested at CONSOL Energy's McElroy mine in April 2006. MSHA felt that all of those systems needed a significant amount of work before they were ready for use in a underground coal mining environment. The agency continues to work with these, and other manufacturers, to assist in arranging for field demonstration and then to gain MSHA approval.

  11. Recovery of oil from underground drill sites

    1991-01-01

    This paper reports that a significant quantity of oil is left in reservoirs after conventional oil recovery techniques have been applied. In West Virginia and Pennsylvania alone, this oil has been estimated at over 4.5 billion barrels (0.72 billion m 3 ). Conventional recovery methods are already being used when applicable. But a new recovery method is needed for use in reservoirs that have been abandoned. One alternative method for recovery of the residual oil is known as oil recovery from underground drill sites. This recovery technology is a combination of proven methods and equipment from the petroleum, mining, and civil construction industries. Underground oil recovery can be an economically viable method of producing oil. This has been shown in producing fields, field tests, and feasibility, studies. Faced with decreasing domestic oil production, the petroleum industry should give serious consideration to the use of oil recovery from underground drill sites as a safe, practical, and environmentally sensitive alternative method of producing oil from many reservoirs

    Estimating the short and long-term economical impact of large-scale damaging events such as earthquakes, tsunamis or tropical storms is an important component of risk assessment, whose outcomes are routinely used to improve risk awareness, optimize investments in prevention and mitigation actions, as well as to customize insurance and reinsurance rates to specific geographical regions or single countries. Such estimations can be carried out by modeling the whole causal process, from hazard assessment to the estimation of loss for specific categories of assets. This approach allows a precise description of the various physical mechanisms contributing to direct seismic losses. However, it should reflect the underlying epistemic and random uncertainties in all involved components in a meaningful way. Within a project sponsored by the World Bank, a seismic risk study for the Kyrgyz Republic has been conducted, focusing on the assessment of social and economical impacts assessed in terms of direct losses of the residential and public building stocks. Probabilistic estimates based on stochastic event catalogs have been computed and integrated with the simulation of specific earthquake scenarios. Although very few relevant data are available in the region on the economic consequences of past damaging events, the proposed approach sets a benchmark for decision makers and policy holders to better understand the short and long term consequences of earthquakes in the region. The presented results confirm the high level of seismic risk of the Kyrgyz Republic territory, outlining the most affected regions; thus advocating for significant Disaster Risk Reduction (DRR) measures to be implemented by local decision- and policy-makers.

    The southern coastal districts of Laizhou Bay are some of the most important areas for underground brine exploitation in Shandong Province. Recently, these areas have been gradually developed by the underground brine mining industry. Such economic interest has led to brine exploitation so that underground brine resources are running out. Based on this phenomenon, this study describes the supply, runoff and draining conditions of the area by collecting and organizing the background information of the studied area. Hydrogeological parameters are then calculated according to pumping tests, and the amount of sustainable resources in the coastal areas of the Southern Bank of Laizhou Bay are then calculated based on the uniform distribution of wells. Under the circumstances of underground brine mining, the exploitation potential of the underground brine is evaluated in accordance with the calculation results of exploitation quantum. Finally, suggestions are provided for the sustainable exploitation of underground brine in the area.

    This report gives a summary overview of the status of international under- ground facilities, in particular as relevant to long-baseline neutrino physics and neutrino astrophysics. The emphasis is on the technical feasibility aspects of creating the large underground infrastructures that will be needed in the fu- ture to house the necessary detectors of 100 kton to 1000 kton scale. There is great potential in Europe to build such a facility, both from the technical point of view and because Europe has a large concentration of the necessary engi- neering and geophysics expertise. The new LAGUNA collaboration has made rapid progress in determining the feasibility for a European site for such a large detector. It is becoming clear in fact that several locations are technically fea- sible in Europe. Combining this with the possibility of a new neutrino beam from CERN suggests a great opportunity for Europe to become the leading centre of neutrino studies, combining both neutrino astrophysics and neutrino beam stu...

Teams monitoring the cooling and powering of the ATLAS solenoid in the control room. The solenoid was cooled down to 4.5 K from 17 to 23 May. The first current was established the same evening that the solenoid became cold and superconductive. 'This makes the ATLAS Central Solenoid the very first cold and superconducting magnet to be operated in the LHC underground areas!', said Takahiko Kondo, professor at KEK. Though the current was limited to 1 kA, the cool-down and powering of the solenoid was a major milestone for all of the control, cryogenic, power and vacuum systems-a milestone reached by the hard work and many long evenings invested by various teams from ATLAS, all of CERN's departments and several large and small companies. Since the Central Solenoid and the barrel liquid argon (LAr) calorimeter share the same cryostat vacuum vessel, this achievement was only possible in perfe...

  5. FAST goes underground

    1985-01-01

    The FAST-M Cost Estimating Model is a parametric model designed to determine the costs associated with mining and subterranean operations. It is part of the FAST (Freiman Analysis of Systems Techniques) series of parametric models developed by Freiman Parametric Systems, Inc. The rising cost of fossil fuels has created a need for a method which could be used to determine and control costs in mining and subterranean operations. FAST-M fills this need and also provides scheduling information. The model works equally well for a variety of situations including underground vaults for hazardous waste storage, highway tunnels, and mass transit tunnels. In addition, costs for above ground structures and equipment can be calculated. The input for the model may be on a macro or a micro level. This allows the model to be used at various stages in a project. On the macro level, only general conditions and specifications need to be known. On the micro level, the smallest details may be included. As with other FAST models, reference cases are used to more accurately predict costs and scheduling. This paper will address how the model can be used for a variety of subterranean purposes

    Full Text Available The purpose of this study was to investigate the maximum annual profit of proposed three project plants as follows: (i a generation process of activated carbon (AC prepared from coconut shells; (ii a regeneration process of spent AC obtained from petrochemical industries; and (iii a project combined the AC generation process with the regeneration process. The maximum annual profit obtained from the sole regeneration plant was about 1.2- and 15.4- fold higher than that obtained from the integrated and the generation plants, respectively. The sensitivity of selected variables to net present value (NPV, AC sales price was the most sensitive to NPV while fixed costs of generation and regeneration, and variable cost of regeneration were the least sensitive to NPV. Based on the optimal results of each project plant, the economic indicators namely NPV, return on investment (ROI, internal rate of return (IRR, and simple payback period (SPP were determined. Applying a rule of thumb of 12% IRR and 7-year SPP, the AC sales prices for the generation, regeneration, and integrated plants were 674.31, 514.66 and 536.66 USD/ton of product, respectively. The economic analysis suggested that the sole regeneration project yields more profitable.

  8. Radiometric surveys in underground environment

    Due to their ability to travel through the air for several metres, gamma-rays emitted from natural radioactive elements can be successfully used in surveys carried out both with airborne and ground equipments. Besides the concentration of the radio-elements contained in rocks and soils and the intrinsic characteristics of the gamma-ray detector, the detected count rate depends on the solid angle around the spectrometer. On a flat outcrop, ground spectrometry detects the radiation ideally produced by a cylindrical mass of rock of about two metres in diameter and thickness of about half a meter. Under these geometrical conditions, the natural radioactivity can be easily evaluated. With operating conditions different from the standard ones, such as at the edge of an escarpment, the count rate halves because of the missing material, whereas in the vicinity of a rock wall the count rate will increase. In underground environment, the recorded count rate may even double and the in situ assessment of the concentration of radio-elements may be rather difficult, even if the ratios between the different radio-elements may not be affected. We tested the applicability of gamma-ray spectrometry for rapid assessment of the potential hazard levels related to radon and radiation dose rate in underground environment. A mine shaft, located in a zone of uranium enrichment in Liguria (Italy), has been investigated. A preliminary ground radiometric survey was carried out to define the extent of the ore deposit. Then, the radiometric investigation was focussed on the mine shaft. Due to rock mass above the shaft vault, the background gamma radiation can be considered of negligible influence on measurements. In underground surveys, besides deviations from a flat geometry, factors controlling radon exhalation, emanation and stagnation, such as fractures, water leakage and the presence of ventilation, should be carefully examined. We attempted to evaluate these control factors and collected

    1983-01-01

    This paper discusses technical developments that may enable uranium mine operators to improve engineering controls of radon daughter concentrations in mines, and developments in regulatory controls. The origin of radon daughters in underground mines is explained. The procedure for sampling and determining the concentration of alpha radiation in sampled air is reviewed. The principal technical development in the last few years has been the perfection and use of a class of meters which determine radon daughter concentrations in an air sample in a matter of two or three minutes without any aging period. A number of underground uranium mine operators are now using ''instant'' type meters and the Mine Safety and Health Administration (MSHA) has approved their use in a number of mines. The difficulty experienced by uranium mine operators in complying with a MSHA regulation which requires that no person be exposed to radon daughter concentrations exceeding 1 Working Level (WL) in any active working place is discussed

    1997-04-01

    The growth and changes--by age, sex, and place of birth--in the structure of the total population of the Buenos Aires metropolitan area and of the subpopulation over 15 years of age and economically active are analyzed for the decade of the 1980s. Study of the economic participation of migrants and its possible influence on levels of employment or unemployment should be carried out within the framework of changes in the population's structure and economic participation. The 1981 and 1991 censuses and the Permanent Survey of Households were the sources of data. Immigration to Argentina has declined considerably in recent years, but it is still a factor in the population growth of metropolitan Buenos Aires. Between the 1981 and 1991 censuses, the population aged 15 and over grew by 10.9/1000, or a total of 827,806 people. Migrants from bordering countries increased in number (by 85,109, or 10.3%) and in proportion to the total population (from 3.9% to 4.6%). Migrant women increased at the highest rate (30.1/1000). The greatest growth occurred among men aged 40 and over and among women aged 35 and over. The growth of the economically active population over age 15 for different groups of national origin, sex, and age showed much greater heterogeneity. In 1991, women from bordering countries represented 3.8% of all women in metropolitan Buenos Aires but 5.7% of the total economically active female population and nearly 7% of the economically active female population aged 35 and over. Women from neighboring countries were responsible for 10.3% of the growth in the economically active female population aged 30-34 and 40-44 between 1981 and 1991. The absolute and relative increases in migrants from neighboring countries and their greater economic participation tend to increase the general level of economic activity.

  17. Fast and safe gas detection from underground coal fire by drone fly over.

    2017-10-01

    Underground coal fires start naturally or as a result of human activities. Besides burning away the important non-renewable energy resource and causing financial losses, burning coal seams emit carbon dioxide, carbon monoxide, sulfur oxide and methane, and is a leading cause of smog, acid rain, global warming, and air toxins. In the U.S. alone, the combined cost of coal-fire remediation projects that have been completed, budgeted, or projected by the U.S. Department of the Interior's Office of Surface Mining Remediation and Enforcement (OSM), exceeds $1 billion. It is estimated that these fires generate as much as 3% of the world's annual carbon dioxide emissions and consume as much as 5% of its minable coal. Considering the magnitude of environmental impact and economic loss caused by burning underground coal seams, we have developed a new, safe, reliable surface measurement of coal fire gases to assess the nature of underground coal fires. We use a drone mounted with gas sensors. Drone collected gas concentration data provides a safe alternative for evaluating the rank of a burning coal seam. In this study, a new method of determining coal rank by gas ratios is developed. Coal rank is valuable for defining parameters of a coal seam such as burn temperature, burn rate, and volume of burning seam. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The aim was to investigate associations between economic stress in childhood and adulthood, and low leisure-time physical activity (LTPA in adulthood from two life course perspectives. The public health survey in Scania in the southernmost part of Sweden in 2012 is a cross-sectional study based on a stratified random sample with 28,029 respondents aged 18–80 (51.7% response rate. Associations between childhood and adult economic stress, and low LTPA were analyzed with logistic regressions. A 14.8% prevalence of men and 13.5% of women had low LTPA (sedentary lifestyle. Low LTPA was associated with higher age, being born abroad, low socioeconomic status, low trust, smoking, poor self-rated health, and economic stress in childhood and adulthood. The odds ratios of low LTPA increased with more accumulated economic stress across the life course in a dose-response relationship. There was no specific critical period (childhood or adulthood, because economic stress in childhood and adulthood were both associated with low LTPA but the associations were attenuated after the introduction of smoking and self-rated health. The accumulation hypothesis was supported because the odds ratios of low LTPA indicated a graded response to life course economic stress. The critical period hypothesis was thus not supported. Economic stress across the life course seems to be associated with low LTPA in adulthood.

  19. SuperCDMS Underground Detector Fabrication Facility

    Energy Technology Data Exchange (ETDEWEB)

    2018-03-01

    The SuperCDMS SNOLAB dark matter experiment processes Ge and Si crystals into fully tested phonon and ionization detectors at surface fabrication and test facilities. If not mitigated, it is anticipated that trace-level production of radioisotopes in the crystals due to exposure to cosmic rays at (or above) sea level will result in the dominant source of background events in future dark matter searches using the current SuperCDMS detector technology. Fabrication and testing of detectors in underground facilities shielded from cosmic radiation is one way to directly reduce production of trace levels of radioisotopes, thereby improving experimental sensitivity for the discovery of dark matter beyond the level of the current experiment. In this report, we investigate the cost and feasibility to establish a complete detector fabrication processing chain in an underground location to mitigate cosmogenic activation of the Ge and Si detector substrates. For a specific and concrete evaluation, we explore options for such a facility located at SNOLAB, an underground laboratory in Sudbury, Canada hosting the current and future experimental phases of SuperCDMS.

    Full Text Available This study aimed to evaluate the economic viability of indirect use activities as developed in a private natural heritage reserve (RPPN. Activities developed in the RPPN include Adventure Tourism and an Ecological Trail. Data were obtained relating to annual number of people visiting the reserve, prices paid to participate in activities, cost of land, maintenance costs and labor costs. Economic criteria used include Net Present Value (VPL and Equivalent Periodic Benefit (BPE. In the 1996-2008 period the number of visitors increased by 6% a year, and the average annual number of visitors to the RPPN was 8,889. It was concluded that indirect use activities in the RPPN are economically viable and can coexist with other direct soil use activities such as eucalyptus cultivation.

  1. War protected underground siting of nuclear power plants -a summary

    International Nuclear Information System (INIS)

    1974-06-01

    In connection with studies concerning the need of war protected nuclear power production the technical and economical conditions with war protection of nuclear power plants have been studied within CDL. Comprehensively one have shown that no technical construction obstacles for siting a nuclear power plant underground exist that the additional costs for underground siting with price level mid 1973 are some 175-250 MSwCr (In today's price level 250 MSwCr will probably correspond to some 300 MSwCr per unit) and that the construction time is some one year longer than for an above ground plant. A study ought to examine more closely the consequences of underground siting from a radiological point of view and what demands on that occasion ought to be put on the technical design. (author)

  2. Radioactivity source terms for underground engineering application

    Tewes, H A [Lawrence Radiation Laboratory, Livermore, CA (United States)

    1969-07-01

    The constraints on nuclide production are usually very similar in any underground engineering application of nuclear explosives. However, in some applications the end product could be contaminated unless the proper nuclear device is used. This fact can be illustrated from two underground engineering experiments-Gasbuggy and Sloop. In the Gasbuggy experiment, appreciable tritium has been shown to be present in the gas currently being produced. However, in future gas stimulation applications (as distinct from experiments), a minimum production of tritium by the explosive is desirable since product contamination by this nuclide may place severe limitations on the use of the tritiated gas. In Sloop, where production of copper is the goal of the experiment, product contamination would not be caused by tritium but could result from other nuclides: Thus, gas stimulation could require the use of fission explosives while the lower cost per kiloton of thermonuclear explosives could make them attractive for ore-crushing applications. Because of this consideration, radionuclide production calculations must be made for both fission and for thermonuclear explosives in the underground environment. Such activation calculations materials of construction are performed in a manner similar to that described in another paper, but radionuclide production in the environment must be computed using both fission neutron and 14-MeV neutron sources in order to treat the 'source term' problem realistically. In making such computations, parameter studies including the effects of environmental temperature, neutron shielding, and rock types have been carried out. Results indicate the importance of carefully evaluating the radionuclide production for each individual underground engineering application. (author)

    2015-07-01

    Full Text Available This work advances the understanding of compensation demanded for environmental impacts on atmosphere, lakes and rivers, soil, and ocean generated by mining, urban, fishing and agriculture activities. Our aims are to determine whether compensation demanded depends on the standard variables used in the field of risk perception (as perceived risk, public acceptability and trust in regulating authorities, and to explore whether these relationships depend on the environment affected and on the economic activity generating the impacts. General Linear Models were used to analyze survey responses from 427 citizens of Santiago, Chile. Results showed that compensation demanded depends on perceived risk, acceptability, and on the economic activity, but not on the environment affected. Acceptability depends on trust in authorities, on perceived risk and on the economic activity. Perceived risk depends on trust, the economic activity and the environment affected. Overall, environmental impacts from the mining industry are perceived as riskier, less acceptable, and have a higher compensation demanded than those generated by the other sectors. These results suggest that to achieve sustainable development, regulations should consider not only environmental impacts but also the economic activity originating them.

    Full Text Available Business subjects in any national economy perform activities results of which are products, services or goods directly distributed to the market network. Volume of products differs according to the level of operational facilities, number of producers and the level of their facilities. Based on the development of information technology, there arise new specialization fields and new ranges of goods. Classification criteria are developed to qualify level of production and for enlistment of a firm to a particular branch. Currently the criteria of production classification are being developed. The understanding of these principles is particularly important on the bachelor level of the specialization Trade Management, where students are getting acquainted with the characteristics of goods, creative and degradation influences on utility, etc. Students are encouraged to understand how the quality and criteria mentioned above influence market prices. Teaching emphasis is put on the complexity of food assortment and the knowledge of Czech and EU legalislation relating to hygienic aspects and health quality of production, processing, and selling of food products. This complex procedure enables to obtain an overall survey of the origin of particular products, their catering, and sales. This means that the students obtain an idea about the complexity of relations existing among the origin of products, their sales and their consumption.

  11. Study for urbanization corresponding to socio-economic activities in Savannaket, Laos using satellite remote sensing

    International Nuclear Information System (INIS)

    Kimijiama, S; Nagai, M

    2014-01-01

    In Greater Mekong Sub-region (GMS), economic liberalization and deregulation facilitated by GMS Regional Economic Corporation Program (GMS-ECP) has triggered urbanization in the region. However, the urbanization rate and its linkage to socio-economic activities are ambiguous. The objectives of this paper are to: (a) determine the changes in urban area from 1972 to 2013 using remote sensing data, and (b) analyse the relationships between urbanization with respect to socio-economic activities in central Laos. The study employed supervised classification and human visible interpretation to determine changes in urbanization rate. Regression analysis was used to analyze the correlation between the urbanization rate and socio-economic variables. The result shows that the urban area increased significantly from 1972 to 2013. The socio-economic variables such as school enrollment, labour force, mortality rate, water source and sanitation highly correlated with the rate of urbanization during the period. The study concluded that identifying the highly correlated socio-economic variables with urbanization rate could enable us to conduct a further urbanization simulation. The simulation helps in designing policies for sustainable development

    This paper is addressed to the traditional problem of demonstrating the relevance of production theory to management-oriented people. Activity analysis, it is argued, is the most appropriate pedagogic framework within which to commence either a production economics or a farm management course. Production economics theory has not been widely accepted as a useful method for the analysis of practical management problems. The theory has been traditionally presented in terms of continuous function...

    While underground gas storage is technically well established for decades, the presence and activity of microorganisms in underground gas reservoirs have still hardly been explored today. Microbial life in underground gas reservoirs is controlled by moderate to high temperatures, elevated pressures, the availability of essential inorganic nutrients, and the availability of appropriate chemical energy sources. Microbial activity may affect the geochemical conditions and the gas composition in an underground reservoir by selective removal of anorganic and organic components from the stored gas and the formation water as well as by generation of metabolic products. From an economic point of view, microbial activities can lead to a loss of stored gas accompanied by a pressure decline in the reservoir, damage of technical equipment by biocorrosion, clogging processes through precipitates and biomass accumulation, and reservoir souring due to a deterioration of the gas quality. We present here results from molecular and cultivation-based methods to characterize microbial communities inhabiting a porous rock gas storage reservoir located in Southern Germany. Four reservoir water samples were obtained from three different geological horizons characterized by an ambient reservoir temperature of about 45 °C and an ambient reservoir pressure of about 92 bar at the time of sampling. A complementary water sample was taken at a water production well completed in a respective horizon but located outside the gas storage reservoir. Microbial community analysis by Illumina Sequencing of bacterial and archaeal 16S rRNA genes indicated the presence of phylogenetically diverse microbial communities of high compositional heterogeneity. In three out of four samples originating from the reservoir, the majority of bacterial sequences affiliated with members of the genera Eubacterium, Acetobacterium and Sporobacterium within Clostridiales, known for their fermenting capabilities.

    Piaggio, Matías; Padilla, Emilio

    2012-01-01

    This paper explores the relationship between CO 2 emissions and economic activity for 31 countries (28 OECD, Brazil, China, and India) during the period 1950 to 2006 using cointegration analysis. Single country long run relationships are estimated, and equality in the functional form, the parameters, and the turning point, when appropriate, are rejected. This confirms the relevance of considering the differences among countries in the relationship between air pollution and economic activity to avoid wrong estimations and conclusions. - Highlights: ► Path and parameters homogeneity in CO 2 -economic activity relationship is analyzed. ► Longer period than previous studies allows greater overlap between countries' paths. ► We also test turning point homogeneity, which imposes a weaker restriction. ► Functional form, parameters and turning point homogeneity is rejected. ► Individual functional form for the long term relation is determined for each country.

    Natural Radionuclides are present in earth's environment since its origin. The main radionuclides present are {sup 40}K, as well as, {sup 238}U and {sup 232}Th with their decay products. These radionuclides occur in minerals in different activity concentration associated with geological and geochemical conditions, appearing at different levels from point to point in the world. Underground mines may present a high natural background radiation which is due to the presence of these radiogenic heavy minerals. To address this concern, this work outlines on the characterization of the natural radionuclides presence in underground mines in Brazil which are located in many cases on higher radiation levels bed rocks. The radon concentration was measured by using E-PERM Electrets Ion Chamber, AlphaGUARD and CR-39 track etch detectors. The radon progeny was determined by using DOSEman detector. Radon concentration measurement in groundwater was performed by using RAD7 detector. The {sup 238}U and {sup 232}Th activity concentration in ore and soil samples were determined by using Neutron Activation Analysis using TRIGA MARK I IPR-R1 Reactor. Gamma spectrometry was used to determine {sup 226}Ra, {sup 228}Ra and {sup 40}K activity concentrations. The results show that the natural radioactivity varies considerably from mine to mine and that there are not risks of radiological damage for exposed workers in these cases. Based on these data, recommendations for Brazilian regulatory standards are presented. (author)

    Full Text Available The aim of this study is to compute the overall effect size concerning the impact of insurance sector activity on economic growth. The connection of insurance activity and economic growth has been a widely investigated topic due to numerous papers and research attempts performed so far. The results, however, often differ among individual studies. Therefore a comprehensive analysis of the significance of causality from insurance activity, measured by insurance premium, to business cycle fluctuation, is well-required. Using 10 published and unpublished studies, we conduct a meta-analysis of the literature on the impact of insurance activity on economic growth. Insurance premium is taken as the measure of insurance activity. The combined significance test of individual t-statistics is employed. The calculation of the effect size allows understand the true effect relying on synthesis of so far published research with significantly higher amount of observations and better precision. Our results confirm positive effect of insurance activity on economic growth and are particularly important for policy makers who set the policy towards subjects in the insurance market.

    1976-05-20

    Overhead mining railways are usually equipped with a friction wheel drive in underground use. This drive has the advantage over a gear drive that it is more robust and therefore more economic. However, it produces unsatisfactory running for difficult sections with steep gradients up or down or places where deposits of grease and dirt are inevitable. It is proposed to change over to a gear drive at such sections. The high degree of wear, which is characteristic of this type of drive, can be reduced if the drive is only used in difficult sections. It is proposed that the gear drive should be automatically switched on and off by means of stops or contacts on the rails.

    In order to assess the seismic risk for an underground facility, a data base was established and analyzed to evaluate the potential for seismic disturbance. Substantial damage to underground facilities is usually the result of displacements primarily along pre-existing faults and fractures, or at the surface entrance to these facilities. Evidence of this comes from both earthquakes and large explosions. Therefore, the displacement due to earthquakes as a function of depth is important in the evaluation of the hazard to underground facilities. To evaluate potential displacements due to seismic effects of block motions along pre-existing or induced fractures, the displacement fields surrounding two types of faults were investigated. Analytical models were used to determine relative displacements of shafts and near-surface displacement of large rock masses. Numerical methods were used to determine the displacement fields associated with pure strike-slip and vertical normal faults. Results are presented as displacements for various fault lengths as a function of depth and distance. This provides input to determine potential displacements in terms of depth and distance for underground facilities, important for assessing potential sites and design parameters

    The purpose of this Project was to design, build, install and demonstrate the technical feasibility of an underground high temperature superconducting (HTS) power cable installed between two utility substations. In the first phase two HTS cables, 320 m and 30 m in length, were constructed using 1st generation BSCCO wire. The two 34.5 kV, 800 Arms, 48 MVA sections were connected together using a superconducting joint in an underground vault. In the second phase the 30 m BSCCO cable was replaced by one constructed with 2nd generation YBCO wire. 2nd generation wire is needed for commercialization because of inherent cost and performance benefits. Primary objectives of the Project were to build and operate an HTS cable system which demonstrates significant progress towards commercial progress and addresses real world utility concerns such as installation, maintenance, reliability and compatibility with the existing grid. Four key technical areas addressed were the HTS cable and terminations (where the cable connects to the grid), cryogenic refrigeration system, underground cable-to-cable joint (needed for replacement of cable sections) and cost-effective 2nd generation HTS wire. This was the worlds first installation and operation of an HTS cable underground, between two utility substations as well as the first to demonstrate a cable-to-cable joint, remote monitoring system and 2nd generation HTS.

    Full Text Available The object of the work is study of methods for analyzing the current financial and economic performance of a company as well as the usage of existing methods for the assessment of the company in the current and future periods. Analysis of financial and economic performance provides not only assessment of the current situation of a company, but a projection of its future behavior. Thus, the results can be used for planning and prediction. Different ways of handling of economic information are currently used in activity analysis to study the factors influencing the performance of a company and to account its reserves. An objective assessment of the financial and economic situation of the modern enterprise is the crucial part of justified decision-making. It forms the basis for determining the development strategy and acts as one of the key indicators for investors and creditors. Tracking and evaluating the effectiveness of a company requires above all comprehensive assessment of its financial and economic activities, monitoring the implementation of decisions, and identification of reserves for improvement. The process of activity analysis requires generalization of models which allow using their results both as a guide for future development of the economic system as well as a base for comparison and evaluation of the present state of the company. This enables justified decision making in particular situations and clarifies usage of existing methods for assessment of the company in the current and future periods. Results. Financial and economic activities of a company require comprehensive analysis, which may be carried out in the following steps: formulating and analyzing business objectives of the company, forming the information basis, constructing a comparison table, analyzing the data, producing a comprehensive rating score of the financial and economic situation of the company. Comprehensive rating score should take into account all

    Full Text Available The uneven distribution of economic activity in Russia promotes the differentiation of its constituent entities by level of development. Regions are independent participants of economic relations, and they often act as competitors rather than partners. Agglomeration effects arise in more successful regions and contribute to the concentration of resources, manufacturing enterprises, service providers, skilled workers, and scientific and technological knowledge. The aim of the study, the results of which are reflected in the paper, is to identify the factors and assess their impact on the concentration (dispersion of economic activity on the basis of Russia’s regions. The paper describes the benefits of agglomeration processes from the standpoint of economic geography, allocation theory and international trade theory. The concentration of economic activity in Russia’s regions is estimated by the Herfindahl–Hirschman index of industrial production taking into consideration the volume of investments in fixed capital and the number of people employed in the economy in Russia’s regions in 1990–2013. It is determined that fixed capital investments have the propensity to concentrate, but react strongly to economic crises. Labor resources, by contrast, are distributed relatively evenly, and their concentration in certain regions is increasing steadily. The article considers key factors such as wage growth, distance to large cities, direct foreign investment, road network density, the degree of development of the services sector in the region. The factor model is constructed using the least squares method. The authors conclude that the growth of wages in the region (relative to national average has a negative effect on the concentration of economic activity. There is a positive correlation between the growth of direct foreign investment and the density of hard surface roads. The development of services has the greatest positive impact on

    Physical inactivity has reached epidemic proportions in modern society. Abundant evidence points to a causal link between physical inactivity and increased risk for numerous noncommunicable diseases, such as some types of cancer and heart disease, as well as premature mortality. Yet, despite this overwhelming evidence, many individuals do not meet the recommended amount of physical activity required to achieve maximum health benefits. Because primary care physicians' advice is highly regarded, clinicians have the unique opportunity to play an important role in enabling patients to modify their behavior at the point of care with the goal of guiding patients to adopt and maintain an active lifestyle. In the current study, the authors evaluate pertinent literature from the fields of medicine/public health and economics/psychology to suggest a comprehensive approach to physical activity counseling at the primary care level. They first examine the public health approach to physical activity counseling, and then proceed to offer insights from behavioral economics, an emerging field that combines principles from psychology and economics. The application of key behavioral economics tools (eg, precommitment contracts, framing) to physical activity counseling in primary care is elaborated.

    Full Text Available This paper studies the impact of VAT upon the economic activity in Romania. By developing a new mathematical model we offer several dy-namic and effcient possibilities for observing the modifcations caused by the temporary reduc-tion of taxes upon the personal incomes which suggest that the resulting additional incomes are often saved and less consumed. Analyzing several temporary reductions in incomes, the model describes also a scheme regarding the developments of economic growth. Based on this scheme, are revealed the different arrangements in which a present economic activity infuences a future one. According to the proposed model, it is highlighted that the national income increases as a response to the aggregated demand.

    Full Text Available The Chinese government has promulgated a de-capacity policy for economic growth and environmental sustainability, especially for the iron and steel industry. With these policies, this study aimed to monitor the economic activities and evaluate the production conditions of an iron and steel factory based on satellites via Landsat-8 Thermal Infrared Sensor (TIRS data and high-resolution images from January 2013 to October 2017, and propel next economic adjustment and environmental protection. Our methods included the construction of a heat island intensity index for an iron and steel factory (ISHII, a heat island radio index for an iron and steel factory (ISHRI and a dense classifying approach to monitor the spatiotemporal changes of the internal heat field of an iron and steel factory. Additionally, we used GF-2 and Google Earth images to identify the main production area, detect facility changes to a factory that alters its heat field and verify the accuracy of thermal analysis in a specific time span. Finally, these methods were used together to evaluate economic activity. Based on five iron and steel factories in the Beijing-Tianjin-Hebei region, when the ISHII curve is higher than the seasonal changes in a time series, production is normal; otherwise, there is a shut-down or cut-back. In the spatial pattern analyses, the ISHRI is large in normal production and decreases when cut-back or shut-down occurs. The density classifying images and high-resolution images give powerful evidence to the above-mentioned results. Finally, three types of economic activities of normal production, shut-down or cut-back were monitored for these samples. The study provides a new perspective and method for monitoring the economic activity of an iron and steel factory and provides supports for sustainable development in China.

    Full Text Available The lack of balance of national budgets and, in particular, of the social security budget, makes decision makers to look increasingly to the characteristics of the labour market and to the general output of economic activity. The better a country is placed in terms of the technological performance of economic activities, which favours an increased labour productivity, the higher are the values of the gross domestic product of the state's general income, and the country's possibility to afford a social policy that is more adapted to the needs of the population. Innovation performance classifies EU member states into four groups, each of these groups having almost a specific curve of the participation rates according to age and sex. In Romania, the population's activity rates according to age groups in the more developed regions are closer to those in the countries with the best innovation performance, although, as a whole, Romania is placed in the fourth and last group according to innovation results among EU member states. In our country, the activity rates according to age group have decreased in recent years, especially with respect to groups aged 50 or more, although the retirement age for men is the highest among EU countries. The increase of labour productivity has boosted economic growth in the recent past but, because of the lack of coherent economic policies, this growth has not. In Romania, activity rates for certain age groups were higher three decades ago and even in the first years of the transition to the market economy. Several scenarios for the projection of rates of participation to economic life until 2020, according to age groups are useful - and, possibly, also realistic, even if the (optimistic scenario with the highest activity rates is taken into account. The latter could be achieved if policies are implemented which enable workforce retention in the country and a better match between the qualification level and profile and

    Full Text Available Unhealthy diet and low levels of physical activity are common behavioural factors in the aetiology of many non-communicable diseases. Recent years have witnessed an upsurge of policy and research interest in the use of taxes and other economic instruments to improve population health.To assemble, configure and analyse empirical research studies available to inform the public health case for using economic instruments to promote dietary and physical activity behaviour change.We conducted a systematic scoping review of evidence for the effects of specific interventions to change, or general exposure to variations in, prices or income on dietary and physical activity behaviours and corollary outcomes. Systematic electronic searches and parallel snowball searches retrieved >1 million study records. Text mining technologies were used to prioritise title-abstract records for screening. Eligible studies were selected, classified and analysed in terms of key characteristics and principal findings, using a narrative, configuring synthesis focused on implications for policy and further research.We identified 880 eligible studies, including 192 intervention studies and 768 studies that incorporated evidence for prices or income as correlates or determinants of target outcomes. Current evidence for the effects of economic instruments and exposures on diet and physical activity is limited in quality and equivocal in terms of its policy implications. Direct evidence for the effects of economic instruments is heavily skewed towards impacts on diet, with a relative lack of evidence for impacts on physical activity.The evidence-based case for using economic instruments to promote dietary and physical activity behaviour change may be less compelling than some proponents have claimed. Future research should include measurement of people's actual behavioural responses using study designs capable of generating reliable causal inferences regarding intervention

  7. Gender, aging, and the economics of "active aging": Setting a new research agenda.

    Science.gov (United States)

    2018-01-01

    The world is aging, and the percentages of older people are on a dramatic ascent. This dramatic demographic aging of human society is not gender neutral; it is mostly about older women. One of the key policy approaches to address the aging revolution is known as "active aging," crystalized by the WHO in 2002 by three pillars: participation, health, and security. The active aging policy has financial and economic aspects and affects both men and women. However, as argued in this article, a gender-based approach has not been adopted within the existing active aging framework. Therefore, a new gender-specific research agenda is needed, one that focuses on an interrelation between gender and different economic aspects of "active aging" from international, comparative, cultural, and longitudinal perspectives.

    2014-01-01

    Highlights: • Adjustment dynamics in electricity sources and industrial production are examined. • The Johansen’s method with a conditional VEC model was pursued. • Results confirm endogeneity among variables. • Cointegration relationships for fossil and for renewables sources were founded. • Renewables are less affected by disturbance in economic activity. - Abstract: The interactions between electricity generation sources and industrial production in Greece were analysed from August 2004 to October 2013. Greece has been subject to a tough economic adjustment under external financial assistance guidelines. In the meantime, the country has remained committed to international agreements concerning the use of renewables. The variables interact with each other, and this endogeneity has been analysed using a VECM model. A short-run, causal relationship from conventional fossil sources to economic growth, was proved. However, there is no evidence of causal relationships from renewable electricity to economic growth, either in the short- or long-run. Only economic growth gives rise to renewable electricity, whether in the short- or long-run. A fresh insight on the current state of dynamics between electricity sources within an electricity generation system, is thus added to the literature. These findings will inform energy policymakers in designing policies both to encourage the incorporation of national technology into renewables and to reduce electricity consumption without hampering economic growth

    Full Text Available The purpose of the paper is to substantiate, on the real figures, the need for enterprise’s financial and economic activities analysis as a condition of management decisions making to achieve the success of the company. Methodology. The research is based on a comparison and analysis of data from the organization top management. So using matrix analysis in the paper, the financial and economic activities effectiveness is evaluated. Based on these calculations, it is possible to make conclusions about the necessity of an identified management decisions regarding the future activity of the company. Results. Daily managers of various function levels accept hundreds and thousands of decisions regarding seemingly slight problems of the organization in general. At the same time, every such a decision, especially relating to the activity of the whole structure, should be clearly justified. Such a need stems from the fact that every decision leads to certain consequences. If there is a need to make a decision relating to the future of the enterprise (e.g., embodiment, reorganization, etc., it should be based on the data of the entire structure. And that is generally very difficult to do. Many factors complicate the possibility of comprehensive evaluation of the company’s activity. At the same time, analysis of basic indicators will provide the specialist with some directions according to which the priority of the analysis can be indicated and appropriate management decision can be made. Practical implications. It is built an effectiveness matrix of financial and economic activities of the enterprise. Analysis of financial and economic activities makes it possible to design necessary strategic and tactical plan for the enterprise development, revealing its reserves of production efficiency increasing.

    The causal relationships among marine energy consumption, greenhouse gas emissions from international shipping, and economic growth for Kyoto Protocol Annex I countries for the period of 1990 to 2006 are discussed. The real gross domestic product is used as a proxy for economic activity. The United States is also discussed because it was the main global polluter before 2006. The co-integration methodology and an error-correction model are used to examine the causal relationships. The empirical results show that marine energy consumption and GDP are the main factors of increased GHG emissions in the short-run, and that economic activity significantly increased emissions in the long-run. Emissions from shipping are more closely related to marine energy consumption than to economic activity. Hence, policies for mitigating greenhouse gas emissions from marine shipping need to focus on greater energy efficiency in the design of ship engines and hulls. - Highlights: ► Energy consumption and GDP are the main causes to increased GHG emissions in the shipping industry. ► Emissions from shipping are more closely related to energy consumption than to GDP. ► Policies to mitigate GHG emissions from shipping industry should focus on the engine and hull design.

    Full Text Available Abstract. Once with the Romania adhering at the European Union the public accounting system was transformed and adapted according to the requirements imposed by the international public sector accounting standards (IPSAS.This fact had imposed the appearance of legislative norms and provisions adapted to the actual requirements, by taking into account the growing and complex level of economic activities where the irreversible process of globalization takes place. The changes due to the economic politics, especially the new configuration of the international economic relations, relations characterized by an intense and irreversible process of globalization, have conducted to the implementation of a unitary and uniform legislation, particularly for the member states of EU. The accounting reform has begun through the harmonization of legislation according to the requirements and provisions of International Accounting Standards and European Directives.  The ampleness and the rapid rhythm of informational society’s development have implicitly leaded to the development of accounting information’s importance and dimension. The decisive role of the accounting information had conducted to the accentuated growth of the interest, manifested at all informational society’s level, from the development of activities in financial and economical domain point of view. The accounting normalization process imposed the development of norms and provisions necessary to the drawing up of accounting documents, by defying methods and a specialized terminology, applied in the activity of entities and accounting specialists.

    Full Text Available As noted by the academician N. P. Fedorenko, «economic incentives is quite rightly regarded as a force deliberately included in the system of optimal functioning of the economy». Thus, the considered problem is relevant for not only the founders and owners of individual firms and corporations, but also for the economy as a whole. The purpose of this research is to develop a theoretical and methodological approach to solving the problem of stimulation of entrepreneurship, innovation and investment activity in industrial enterprises (and other organizations on the basis of economic incentives of their employees, ensuring the implementation of this process. The problem lies in the construction of such economic mechanism that would provide incentives at not only the level of the Corporation as a whole, but at each firm (enterprise and division of firm level and would affect the activity of each employee. This mechanism will be viable only if the distribution of the profit received from realization of work and services in all divisions of the enterprise, firms, corporations involved in carrying out such works in accordance with the quantity and effectiveness of their work based on value added. It uses the principle of self-organization and self-government based on the allocation of the final economic result of their activities using specially designed intra-firm, transfer prices.

The complexity and diversity of the forms of socio-ecological and ecological-economic issues at different levels of the economic system leads to the development of many directions and views on the expansion of the management process of these levels (global, national, regional, local and techniques from rigid-deklorative state before combination with the market. In this respect, the neoclassical economic theory actively generated new analytical ideas and concept that enables to respond adequately to emerging economic realities. So we can distinguish the following approaches to regulate environmental management activities: T. Malthus and D.

    Full Text Available A modern city space is a space where in the vertical and horizontal direction dynamic, non-linear processes exist, similar as in nature. Alongside the “common” city surface, cities have underground spaces as well that are increasingly affecting the functioning of the former. It is the space of material and cybernetic communication/transport. The psychophysical specifics of using underground places have an important role in their conceptualisation. The most evident facts being their limited volume and often limited connections to the surface and increased level of potential dangers of all kinds. An efficient mode for alleviating the effects of these specific features are artistic interventions, such as: shape, colour, lighting, all applications of the basic principles of fractal theory.

    Harnessing the economic potential of the oceans is key to combating poverty, enhancing food security, and strengthening economies. But the concomitant risk of intensified resource extraction to migratory species is worrying given these species contribute to important ecological processes, often underpin alternative livelihoods, and are mostly already threatened. We thus sought to quantify the potential conflict between key economic activities (5 fisheries and hydrocarbon exploitation) and sea turtle migration corridors in a region with rapid economic development: southern and eastern Africa. We satellite tracked the movement of 20 loggerhead (Caretta caretta) and 14 leatherback (Dermochelys coriacea) turtles during their postnesting migrations. We used movement-based kernel density estimation to identify migration corridors for each species. We overlaid these corridors on maps of the distribution and intensity of economic activities, quantified the extent of overlap and threat posed by each activity on each species, and compared the effects of activities. These results were compared with annual bycatch rates in the respective fisheries. Both species' 3 corridors overlapped most with longline fishing, but the effect was worse for leatherbacks: their bycatch rates of approximately 1500/year were substantial relative to the regional population size of 50 years of conservation, potentially affecting >80% of loggerheads, 33% of the (critically endangered) leatherbacks, and their nesting beaches. We support establishing blue economies (i.e., generating wealth from the ocean), but oceans need to be carefully zoned and responsibly managed in both space and time to achieve economic (resource extraction), ecological (conservation, maintenance of processes), and social (maintenance of alternative livelihood opportunities, alleviate poverty) objectives. © 2017 Society for Conservation Biology.

    As reported in the CERN Bulletin, Issue No.30-31, 25 July 2005 The ATLAS barrel Tile calorimeter has recorded its first events underground using a cosmic ray trigger, as part of the detector commissioning programme. This is not a simulation! A cosmic ray muon recorded by the barrel Tile calorimeter of ATLAS on 21 June 2005 at 18:30. The calorimeter has three layers and a pointing geometry. The light trapezoids represent the energy deposited in the tiles of the calorimeter depicted as a thick disk. On the evening of June 21, the ATLAS detector, now being installed in the underground experimental hall UX15, reached an important psychological milestone: the barrel Tile calorimeter recorded the first cosmic ray events in the underground cavern. An estimated million cosmic muons enter the ATLAS cavern every 3 minutes, and the ATLAS team decided to make good use of some of them for the commissioning of the detector. Although only 8 of the 128 calorimeter slices ('superdrawers') were included in the trigg...

  12. Radionuclides in an underground environment

    Thompson, J.L.

    1996-01-01

    In the 100 years since Becquerel recognized radioactivity, mankind has been very successful in producing large amounts of radioactive materials. We have been less successful in reaching a consensus on how to dispose of the billions of curies of fission products and transuranics resulting from nuclear weapons testing, electrical power generation, medical research, and a variety of other human endeavors. Many countries, including the United States, favor underground burial as a means of disposing of radioactive wastes. There are, however, serious questions about how such buried wastes may behave in the underground environment and particularly how they might eventually contaminate water, air and soil resources on which we are dependent. This paper describes research done in the United States in the state of Nevada on the behavior of radioactive materials placed underground. During the last thirty years, a series of ''experiments'' conducted for other purposes (testing of nuclear weapons) have resulted in a wide variety of fission products and actinides being injected in rock strata both above and below the water table. Variables which seem to control the movement of these radionuclides include the physical form (occlusion versus surface deposition), the chemical oxidation state, sorption by mineral phases of the host rock, and the hydrologic properties of the medium. The information gained from these studies should be relevant to planning for remediation of nuclear facilities elsewhere in the world and for long-term storage of nuclear wastes

    Disposal of low- and intermediate-level radioactive wastes by shallow land burial, emplacement in suitable abandoned mines, or by deep well injection and hydraulic fracturing has been practised in various countries for many years. In recent years considerable efforts have been devoted in most countries that have nuclear power programmes to developing and evaluating appropriate disposal systems for high-level and transuranium-bearing waste, and to studying the potential for establishing repositories in geological formations underlaying their territories. The symposium, organized jointly by the IAEA and OECD's Nuclear Energy Agency in cooperation with the Geological Survey of Finland, provided an authoritative account of the status of underground disposal programmes throughout the world in 1979. It was evidence of the experience that has been gained and the comprehensive investigations that have been performed to study various options for the underground disposal of radioactive waste since the last IAEA/NEA symposium on this topic (Disposal of Radioactive Waste into the Ground) was held in 1967 in Vienna. The 10 sessions covered the following topics: National programme and general studies, Disposal of solid waste at shallow depth and in rock caverns, underground disposal of liquid waste by deep well injection and hydraulic fracturing, Disposal in salt formations, Disposal in crystalline rocks and argillaceous sediments, Thermal aspects of disposal in deep geological formations, Radionuclide migration studies, Safety assessment and regulatory aspects.

    With the rapid economic development, the serious air pollution in Beijing attracts increasing attention in the last decade. Seen as one whole complex and grey system, the causal relationship between the social development and the air pollution in Beijing has been quantitatively analyzed in this paper. By using the grey relational model, the aim of this study is to explore how the socio-economic and human activities affect on the air pollution in the city of Beijing, China. Four air pollutants, as the particulate matter with size 2.5 micrometers or less (PM2.5), particulate matter with size 10 micrometers or less (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NOx), are selected as the indicators of air pollution. Additionally, fifteen socio-economic indicators are selected to account for the regional socio-economic characteristics (economy variables, energy consumption variables, pollution emissions variables, environment and construction activity variables). The results highlight that all variables are associated with the concentrations of the four selected air pollutants, but with notable differences between the air pollutants. Most of the socio-economic indicators, such as industrial output, total energy consumption are highly correlated with PM2.5, while PM10, SO2, and NOx present in general moderate correlations with most of the socio-economic variables. Contrary to other studies and reports this study reveals that vehicles and life energy do not have the strongest effect on air pollution in Beijing. This study provides useful information to reduce air pollution and support decision-making for sustainable development.

  20. Peer outreach work as economic activity: implications for HIV prevention interventions among female sex workers.

    Directory of Open Access Journals (Sweden)

    Annie George

    Full Text Available Female sex workers (FSWs who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers' economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers' relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

There is established that a stage of maturity not always gives way to decline stage and in the next to crisis stage. Life processes of "ageing" of the enterprise can be successfully resisted. It is proved that the stage of maturity of the enterprise is associated with a "crisis of stability". Getting into the stages of recession, growth or maintaining stability becomes the way out of the crisis. The authors prove that there are such zones of staying on the life cycle’s curve in the practice of commercial organizations functioning when it is necessary to use the mechanism of stabilization (at detection of "crisis of stability", at transfer from the stage of maturity to the stage of recession and at diagnostics of hit to the stage of recession. In this regard the authors elaborate an economic mechanism for stabilization of the enterprise’s activity as a system of measures aimed at maintaining the achieved financial balance of the enterprise in a long period, which includes the following blocks: information support of the assessment of financial condition; assessment of the level of payment, business and capital stability of the enterprise; determination of the stage of the enterprise’s life cycle; characteristics of the applicable strategy; the need to use the tools for adjust the strategy to stabilize the enterprise’s activity and evaluate the results. At the same time, it is important to focus on maintaining achievable growth rates through the using of special management decisions, along with monitoring the life cycle and controlling the financial condition of the enterprise. The introduction of the economic stabilization mechanism in the enterprise’s activity jointly with the existing organizational and economic mechanism will correct the elements of the basic mechanism and

They greatly affected the socio-economic life of the country. After the economic crisis of heavy industry spread throughout the region and contributed to the emergence of a number of negative factors such as lack of resources, decline and stagnation in metallurgy, machine in order to get help, especially economic. It is proved that the government of the Russian Empire played the role of defender, protector of interests of the most influential entrepreneurs steel. They assisted individual industrialists, which was to provide government contracts, cash flows in the steel industry, provide favorable loans and subsidies for obtaining favorable terms. But such a condescending attitude the Russian Empire carried out solely to establish control in the steel industry, regulate the activities of entrepreneurs. Undoubtedly, during the crisis significantly decreased profit breeders, so the latter tried most of the losses on to the workers. At steel mills reduced production volumes, which led to the closure of factories, increasing the intensity of labor, lower wages, worse off workers, mass unemployment.

  4. Differential activity of Striga hermonthica seed germination stimulants and Gigaspora rosea hyphal branching factors in rice and their contribution to underground communication.

    Directory of Open Access Journals (Sweden)

    Catarina Cardoso

    Full Text Available Strigolactones (SLs trigger germination of parasitic plant seeds and hyphal branching of symbiotic arbuscular mycorrhizal (AM fungi. There is extensive structural variation in SLs and plants usually produce blends of different SLs. The structural variation among natural SLs has been shown to impact their biological activity as hyphal branching and parasitic plant seed germination stimulants. In this study, rice root exudates were fractioned by HPLC. The resulting fractions were analyzed by MRM-LC-MS to investigate the presence of SLs and tested using bioassays to assess their Striga hermonthica seed germination and Gigaspora rosea hyphal branching stimulatory activities. A substantial number of active fractions were revealed often with very different effect on seed germination and hyphal branching. Fractions containing (--orobanchol and ent-2'-epi-5-deoxystrigol contributed little to the induction of S. hermonthica seed germination but strongly stimulated AM fungal hyphal branching. Three SLs in one fraction, putative methoxy-5-deoxystrigol isomers, had moderate seed germination and hyphal branching inducing activity. Two fractions contained strong germination stimulants but displayed only modest hyphal branching activity. We provide evidence that these stimulants are likely SLs although no SL-representative masses could be detected using MRM-LC-MS. Our results show that seed germination and hyphal branching are induced to very different extents by the various SLs (or other stimulants present in rice root exudates. We propose that the development of rice varieties with different SL composition is a promising strategy to reduce parasitic plant infestation while maintaining symbiosis with AM fungi.

The research is conducted on the example of the furniture entities of the Voronezh region and Krasnodar Krai. Any entity constantly uses these or those resources connected with material, labor and finance costs. All resources, which are consumed during a certain production cycle, create a cost budget or the expense plan of the entity, which are the most important economic indicators of activities of any entity. Not always at the entities the attention is properly paid to forecasting of production expenses for a further stage of functioning. Most the entities will organize the activities in such a way that current plans pass from year to year, and at the same time the alternative ways directed to cost reduction in case of production and further sales of products aren't considered. Any entity needs forecasting and planning of costs for the following production stages, for the purposes of innovative development and effective functioning of productive activity of the entity. First, it is necessary for assessment of opportunities when financing productive activity and for further scheduling of expenses, directed to cost reduction and cost reallocation. Having analysed activities of the entities and having studied accounting (financial records, it is revealed that at the entities in 2015 in comparison with 2014, there was a decrease in outputs, but at the same time, the loss is observed. Based on the carried-out analysis, on the example of financial and economic activities of JSC GRAFSKOYE and JSC GKMF, conclusions are drawn, cost reduction allowances in case of production are revealed, and recommendations in

  7. Sinkhole development induced by underground quarrying, and the related hazard

    Sinkholes are extremely widespread in Apulia, a very flat and carbonate region, that acted as the foreland during the phases of building up of the Southern Apenninic Chain in Miocene time. This is due to the presence of soluble rocks throughout the region, that highly predispose the area to this very subtle natural hazard. In addition to the natural setting, which favours their development, sinkholes may also be induced by anthropogenic activities. In the latter sense, underground quarrying represents one of the most dangerous activities in karst areas. Apulia has a long history of quarrying. Since the roman time, the local rocks, from the Cretaceous micritic limestones to the Quaternary calcarenites, have been intensely quarried and used as building and ornamental materials. In several settings of the region, the rocks with the best petrographic characteristics are located at depths ranging from a few to some tens of meters. This caused the opening of many underground quarries, and the development of a complex network of subterranean galleries. Underground quarrying had a great impulse at the turn between the XIX and the XX century, when a large number of quarries was opened. Later on, after the Second World War, most of the quarries were progressively abandoned, even because of the first signs of instability, both underground and at the ground surface. With time, the memory of the presence and development of the underground quarries was progressively lost, with severe repercussions on the safety of the land above the excavated areas. Lack of knowledge of the subterranean pattern of galleries, combined with the expansion of the built-up areas at the surface, resulted in increasing significantly the vulnerability of exposed elements at risk. Events such as the 29 March, 2007, at Gallipoli only by chance did not result in any casualties, when a 15-mt wide and 5-mt deep sinkhole opened in a few hours at a road crossing, above the site of an old underground quarry

  8. Numerical modeling of underground openings behavior with a viscoplastic approach

    Nature is complex and must be approached in total modesty by engineers seeking to predict the behavior of underground openings. The engineering of industrial projects in underground situations, with high economic and social stakes (Alpine mountain crossings, nuclear waste repository), mean striving to gain better understanding of the behavioral mechanisms of the openings to be designed. This improvement necessarily involves better physical representativeness of macroscopic mechanisms and the provision of prediction tools suited to the expectations and needs of the engineers. The calculation tools developed in this work is in step with this concern for satisfying industrial needs and developing knowledge related to the rheology of geo-materials. These developments led to the proposing of a mechanical constitutive model, suited to lightly fissured rocks, comparable to continuous media, while integrating more particularly the effect of time. Thread of this study, the problematics ensued from the subject of the thesis is precisely about the rock mass delayed behavior in numerical modeling and its consequences on underground openings design. Based on physical concepts of reference, defined in several scales (macro/meso/micro), the developed constitutive model is translated in a mathematical formalism in order to be numerically implemented. Numerical applications presented as illustrations fall mainly within the framework of nuclear waste repository problems. They concern two very different configurations of underground openings: the AECL's underground canadian laboratory, excavated in the Lac du Bonnet granite, and the GMR gallery of Bure's laboratory (Meuse/Haute-Marne), dug in argillaceous rock. In this two cases, this constitutive model use highlights the gains to be obtained from allowing for delayed behavior regarding the accuracy of numerical tunnel behavior predictions in the short, medium and long terms.

    Full Text Available The only possibility to ensure a high rate of growth of economic efficiency of production is a result of transition to a predominantly intensive type of development, especially for domestic enterprises in current conditions. The article considers, which concrete factors of the external environment of enterprise impact its activity in the present time and on the territory of Ukraine, and also substantiates the necessity of transition to the mode of «intensification». Scientific novelty consists in approbation of the method of research of the degree of intensification of activity on the example of one of the enterprises of Kharkiv, carrying out foreign economic activity. The system of the scientific and special methods was used: system approach; methods of analysis and synthesis of grouping; economic-mathematical method – the method of analysis of production intensification – to determine the degree of intensity/extensiveness of production at the researched enterprise. The calculations allowed to determine that the relative saving of the aggregate resources at the researched enterprise, using this method, amounted to more than 16 million UAH. Thus, it is possible to speak about expediency of use of the presented method in practice, especially in view of the current condition of enterprises of Ukraine.

    2012-07-01

    The paper analyses the environment pollution state in different case studies of economic activities (i.e. co-generation electric and thermal power production, iron profile manufacturing, cement processing, waste landfilling, and wood furniture manufacturing), evaluating mainly the environmental cumulative impacts (e.g. cumulative impact against the health of the environment and different life forms). The status of the environment (air, water resources, soil, and noise) is analysed with respect to discharges such as gaseous discharges in the air, final effluents discharged in natural receiving basins or sewerage system, and discharges onto the soil together with the principal pollutants expressed by different environmental indicators corresponding to each specific productive activity. The alternative methodology of global pollution index (I (GP)*) for quantification of environmental impacts is applied. Environmental data analysis permits the identification of potential impact, prediction of significant impact, and evaluation of cumulative impact on a commensurate scale by evaluation scores (ES(i)) for discharge quality, and global effect to the environment pollution state by calculation of the global pollution index (I (GP)*). The I (GP)* values for each productive unit (i.e. 1.664-2.414) correspond to an 'environment modified by industrial/economic activity within admissible limits, having potential of generating discomfort effects'. The evaluation results are significant in view of future development of each productive unit and sustain the economic production in terms of environment protection with respect to a preventive environment protection scheme and continuous measures of pollution control.

  17. Impact Analysis of Economic Contributors on Knowledge Creation Activity by Using the Symmetric Decomposition Method

    Kyunam Kim

    2017-10-01

    Full Text Available Recently, several studies using various methods for analysis have tried to evaluate factors affecting knowledge creation activity, but few analyses quantitatively account for the impact that economic determinants have on them. This paper introduces a non-parametric method to structurally analyze changes in information and communication technology (ICT patenting trends as representative outcomes of knowledge creation activity with economic indicators. For this, the authors established a symmetric model that enables several economic contributors to be decomposed through the perspective of ICTs’ research and development (R&D performance, industrial change, and overall manufacturing growth. Additionally, an empirical analysis of some countries from 2001 to 2009 was conducted through this model. This paper found that all countries except the United States experienced an increase of 10.5–267.4% in ICT patent applications, despite fluctuations in the time series. It is interesting that the changes in ICT patenting of each country generally have a negative relationship with the intensity of each country’s patent protection system. Positive determinants include ICT R&D productivity and overall manufacturing growth, while ICT industrial change is a negative determinant in almost all countries. This paper emphasizes that each country needs to design strategic plans for effective ICT innovation. In particular, ICT innovation activities need to be promoted by increasing ICT R&D investment and developing the ICT industry, since ICT R&D intensity and ICT industrial change generally have a low contribution to ICT patenting.

  18. A Psychosocial Approach to Understanding Underground Spaces

    2017-03-01

    Full Text Available With a growing need for usable land in urban areas, subterranean development has been gaining attention. While construction of large underground complexes is not a new concept, our understanding of various socio-cultural aspects of staying underground is still at a premature stage. With projected emergence of underground built environments, future populations may spend much more of their working, transit, and recreational time in underground spaces. Therefore, it is essential to understand the challenges and advantages that such environments have to improve the future welfare of users of underground spaces. The current paper discusses various psycho-social aspects of underground spaces, the impact they can have on the culture shared among the occupants, and possible solutions to overcome some of these challenges.

    The effect of highways and local activities on the quality of groundwater in Ogun State, Nigeria was investigated. This was done by collecting groundwater samples from three different districts in the state, located in Southwestern Nigeria. The water samples collected at 5 m from the highway and control samples collected at 3 km from the highway were analyzed for the following physicochemical parameters: pH, conductivity, chemical oxygen demand, alkalinity, total hardness, total solid, suspended solid, dissolved solid, chloride, sulfate, phosphate, nitrate, phenol, and the metals-lead, zinc, iron, aluminum, sodium, and potassium. The levels of chromium, copper, and cadmium in the samples were below the detectable limit. The levels of the parameters show that there are significant differences between those in the samples and the controls (F test) except for phosphate and phenol. Also, anthropogenic sources (local activities) elevate the levels of different specific parameters, which are related to these activities. Good correlation was observed between traffic density and lead levels as well as between conductivity and dissolved solids. Comparisons with the World Health Organization guidelines indicate that most of the water samples are not suitable for human consumption.

    Technical constraints can leave a considerable freedom in the design of a technology, production or service strategy. Choosing between economical or ecological decision criteria then characteristically leads to controversial solutions of ideal systems. For the adaptation of granular-activated carbon (GAC) fixed beds, various technical factors determine the adsorber volume required to achieve a desired service life. In considering carbon replacement and recycling, a variety of refill strategies are available that differ in terms of refill interval, respective adsorber volume, and time-dependent use of virgin, as well as recycled GAC. Focusing on the treatment of contaminant groundwater, we compare cost-optimal reactor configurations and refill strategies to the ecologically best alternatives. Costs and consumption of GAC are quantified within a technical-economical framework. The emissions from GAC production out of hard coal, transport and recycling are equally derived through a life cycle impact assessment. It is shown how high discount rates lead to a preference of small fixed-bed volumes, and accordingly, a high number of refills. For fixed discount rates, the investigation reveals that both the economical as well as ecological assessment of refill strategies are especially sensitive to the relative valuation of virgin and recycled GAC. Since recycling results in economic and ecological benefits, optimized systems thus may differ only slightly.

  6. Underground test area subproject waste management plan. Revision No. 1

    1996-08-01

    The Nevada Test Site (NTS), located in southern Nevada, was the site of 928 underground nuclear tests conducted between 1951 and 1992. The tests were performed as part of the Atomic Energy Commission and U.S. Department of Energy (DOE) nuclear weapons testing program. The NTS is managed by the DOE Nevada Operations Office (DOE/NV). Of the 928 tests conducted below ground surface at the NTS, approximately 200 were detonated below the water table. As an unavoidable consequence of these testing activities, radionuclides have been introduced into the subsurface environment, impacting groundwater. In the few instances of groundwater sampling, radionuclides have been detected in the groundwater; however, only a very limited investigation of the underground test sites and associated shot cavities has been conducted to date. The Underground Test Area (UGTA) Subproject was established to fill this void and to characterize the risk posed to human health and the environment as a result of underground nuclear testing activities at the NTS. One of its primary objectives is to gather data to characterize the deep aquifer underlying the NTS

We consider a tax evading firm operating simultaneously both in the regular and in the underground economy. We suggest that such a kind of firm, referred to as moonlighting firm, is able...... allocation in the underground production. In fact, a strong and inverse relationship is found, and tax reduction is the best policy to reduce the convenience to produce underground. Wealso confirm the depressing effect on investment of taxation (see, for instance, Summers,1981), so that tax reduction has...

  8. Natural radionuclides in Brazilian underground mines

    2015-01-01

    Rock, soil and water contain "2"3"8U and "2"3"2Th and their decay products. The distribution of these radionuclides differs in terms of activity concentration depending on the mineral type and origin. All ore processing releases long and short half-life radionuclides, mainly radon and its progeny. It is important to monitor this gas and its decay products in underground mines in order to assess the radiological hazards of the exposed workers. On this concern, the present work outlines the characterization of brazilian underground mines with relation to natural radionuclides, specially radon and its progeny. The radon concentration was measured by using E-PERM Electrets Ion Chamber (Radelec), AlphaGUARD (Saphymo GmbH) and CR-39 (Landauer) track etch detectors. The radon progeny was determined by using DOSEman detector. The equilibrium state between radon and its progeny was calculated. Based on these data, the total effective dose for miners was estimated. Moreover, the contribution from the main sources to the radon level inside mines was evaluated. For this, the following detectors were used: measurements of radon concentrations in soil gas were carried out by using AlphaGUARD detector; "2"2"6Ra ("2"1"4Bi), "2"3"2Th e "4"0K specific activity in ore and soil samples were determined by using gamma-ray spectrometry HPGe detector (Canberra); and radon concentration in groundwater samples was performed by using RAD7 (Durridge Inc.). The radon concentration ranged from 113 to 8171 Bq.m"-"3 and the Equilibrium Equivalent Concentration varied from 76 to 1174 Bq.m"-"3. The equilibrium factor mean value was 0.4 (0.2 -0.7). The workers estimated total effective dose ranged from 1 to 22 mSv.a"-"1 (mean 10 mSv.a"-"1). Therefore, results show the importance to assess continually and permanently the radon and its progeny behavior and the need to adopt safety measurements against natural radiation in underground mines environment.

    2008-01-01

    The new Nuclear Power Act and the Nuclear Power Ordinance of 2005 are used in Switzerland to select a site of an underground geologic store for radioactive waste in a substantive planning procedure. The ''Underground Geologic Store Substantive Plan'' is to ensure the possibility to build underground geologic stores in an independent, transparent and fair procedure. The Federal Office for Energy (BFE) is the agency responsible for this procedure. The ''Underground Geologic Store'' Substantive Plan comprises these principles: - The long term protection of people and the environment enjoys priority. Aspects of regional planning, economics and society are of secondary importance. - Site selection is based on the waste volumes arising from the five nuclear power plants currently existing in Switzerland. The Substantive Plan is no precedent for or against future nuclear power plants. - A transparent and fair procedure is an indispensable prerequisite for achieving the objectives of a Substantive Plan, i.e., finding accepted sites for underground geologic stores. The Underground Geologic Stores Substantive Plan is arranged in two parts, a conceptual part defining the rules of the selection process, and an implementation part documenting the selection process step by step and, in the end, naming specific sites of underground geologic stores in Switzerland. The objective is to be able to commission underground geologic stores in 25 or 35 years' time. In principle, 2 sites are envisaged, one for low and intermediate level waste, and one for high level waste. The Swiss Federal Council approved the conceptual part on April 2, 2008. This marks the beginning of the implementation phase and the site selection process proper. (orig.)

    While the immigrant collective in Spain has grown considerably in recent years, little is known about working conditions and their corresponding effects on occupational injury in this group. The objective of this study was to compare the incidences for both fatal and non-fatal injuries in foreign workers to that of Spanish workers in 2005, by autonomous community and economic activity. injury data came from the accident registry of the ministry of labor and social issues, and denominators were taken from available social security affiliation statistics from general and coal mining social security system. Incidence indices for fatal and non-fatal occupational injuries for foreign and spanish workers were calculated. In addition, relative risks and their 95% confidence intervals (95% CI) were calculated by autonomous community and economic activity, using spanish workers as the reference group. Overall, relative risk for occupational injury in foreign workers in 2005 was superior to base risk for both fatal (1.34; 95% CI: 1.11-1.62) and non-fatal injury (1.13; 95% CI: 1.13-1.14), though there were important differences by autonomous community and activity sectors. Compared with Spanish workers, risk for occupational injury was higher for foreign workers in industrial activities, while it was lower in construction, commerce and restaurants and hotels. By autonomous community, Aragón and Catalonia showed the highest risks for foreign workers. A higher risk for occupational injury among foreign workers is confirmed, and may be higher than that observed. The differences in risk among economic activities and autonomous communities require more detailed analysis.

    This research commenced in 1994 for the purpose of providing safety and environmental measures of underground mines where the mobile diesel equipment are operating. In this last research year, researches on filtering of diesel particulate matter, design of underground layout and disaster prevention have been carried out. 1) A study to reduce DPM(Diesel Particulate Matter) emission: It was known that water scrubber is only one practical way to reduce DPM emission as of now. There are several kinds of the sophisticated DPM filters, but it is not practical yet to be used in underground equipment due to the many adverse effects of the devices such as tremendous increase of SOx, NOx and back pressure etc. 2) Design of underground layout and their maintenance: Layout of underground structure has to be designed based on rock mechanical analysis and the concept of active support has to be adopted considering the large openings are requested to accommodate heavy duty diesel equipment in underground. Rock bolt and shotcrete will be the most applicable method to support such a large dimensional tunnels. 3) A study for disaster prevention in the case of the underground fire: There are two categories of possible disaster or hazard in workings where diesel equipment are operating. One is the disasters by exhaust pollutants and the other is the underground fire. (author). 35 refs., 27 tabs., 56 figs.

  12. Application of Three Existing Stope Boundary Optimisation Methods in an Operating Underground Mine

    2017-12-01

    The underground mine planning and design optimisation process have received little attention because of complexity and variability of problems in underground mines. Although a number of optimisation studies and software tools are available and some of them, in special, have been implemented effectively to determine the ultimate-pit limits in an open pit mine, there is still a lack of studies for optimisation of ultimate stope boundaries in underground mines. The proposed approaches for this purpose aim at maximizing the economic profit by selecting the best possible layout under operational, technical and physical constraints. In this paper, the existing three heuristic techniques including Floating Stope Algorithm, Maximum Value Algorithm and Mineable Shape Optimiser (MSO) are examined for optimisation of stope layout in a case study. Each technique is assessed in terms of applicability, algorithm capabilities and limitations considering the underground mine planning challenges. Finally, the results are evaluated and compared.

    Objective walkability is an important correlate of adults' physical activity. Studies investigating the relation between walkability and children's physical activity are scarce. However, in order to develop effective environmental interventions, a profound investigation of this relation is needed in all age groups. The aim of this study was to investigate the association between objective walkability and different domains of children's physical activity, and to investigate the moderating effect of neighborhood socio-economic status in this relation. Data were collected between December 2011 and May 2013 as part of the Belgian Environmental Physical Activity Study in children. Children (9-12 years old; n = 606) were recruited from 18 elementary schools in Ghent (Belgium). Children together with one of their parents completed the Flemish Physical Activity Questionnaire and wore an accelerometer for 7 consecutive days. Children's neighborhood walkability was calculated using geographical information systems. Multilevel cross-classified modeling was used to determine the relationship between children's PA and objectively measured walkability and the moderating effect of neighborhood SES in this relation. In low SES neighborhoods walkability was positively related to walking for transportation during leisure time (β = 0.381 ± 0.124; 95% CI = 0.138, 0.624) and was negatively related to sports during leisure time (β = -0.245 ± 0.121; 95% CI = -0.482, -0.008). In high socio-economic status neighborhoods, walkability was unrelated to children's physical activity. No relations of neighborhood walkability and neighborhood socio-economic status with cycling during leisure time, active commuting to school and objectively measured moderate- to vigorous-intensity physical activity were found. No univocal relation between neighborhood walkability and physical activity was found in 9-12 year old children. Results from international adult studies

  14. Territorial Identity and Grassroots Economic Activism: The Politicization of Farmers’ Mobilizations in the French Basque Country

    Full Text Available The French Basque Country (FBC represents an emblematic case of the politicization of local development through grassroots economic activism. These mobilizations are particularly obvious in the agricultural sector. Based on a qualitative research on small farmers’ organizations and short food circuits, this article shows that Basque farmers’ mobilizations constitute a case of a dual politicization of small-scale farming and territorial identity. This process has gone through two phases: the first period (1970-2000 was characterized by the politicization of local productive systems. Throughout the decade 2000-2010, a new mode of grassroots economic activism emerged, signalled by new alliances between producers and consumers, and by an increasing ideological pluralism. Two case studies illustrate these developments. The first relates to a case of explicit politicization with the controversy around the foundation in 2005 of an alternative Basque Chamber of Agriculture. The second case study is devoted to the development of short food circuits in the FBC, considered here as a case of implicit politicization of the encounter between productive and consumption circuits. Both cases illustrate the politicization of new economic social movements, and the constant overlapping of sectoral and territorial claims in the Basque territory.

    Full Text Available This article deals with analysis of the South Moravian region population economic activity and unemployment state and development. The analysis of the population economic activity and unemployment is a part of the demographic, social and economic population analysis. The unemployment is considered to be an unfavourable effect, but its low rate is a natural part of the market economy. The unemployment was from the general and registered unemployment rate in years 1995–2003 point of view evaluated. Some indicators of the South Moravian region were with the whole Czech Republic compared. The unemployment in the South Moravian region marked a negative development in mentioned period and in the year 2003 achieved value of 11.45%. The trend of the unemployment development was defined and also the seasonal character with the seasonal indexes was analysed. The highest unemployment was proved in winter months (January–March and least in May and June. There was proved the high dependency rate among the number of vacancies, the number of applicants for one vacancy and unemployment rate.

    The potential seismic risk for an underground nuclear waste repository will be one of the considerations in evaluating its ultimate location. However, the risk to subsurface facilities cannot be judged by applying intensity ratings derived from the surface effects of an earthquake. A literature review and analysis were performed to document the damage and non-damage due to earthquakes to underground facilities. Damage from earthquakes to tunnels, s, and wells and damage (rock bursts) from mining operations were investigated. Damage from documented nuclear events was also included in the study where applicable. There are very few data on damage in the subsurface due to earthquakes. This fact itself attests to the lessened effect of earthquakes in the subsurface because mines exist in areas where strong earthquakes have done extensive surface damage. More damage is reported in shallow tunnels near the surface than in deep mines. In mines and tunnels, large displacements occur primarily along pre-existing faults and fractures or at the surface entrance to these facilities.Data indicate vertical structures such as wells and shafts are less susceptible to damage than surface facilities. More analysis is required before seismic criteria can be formulated for the siting of a nuclear waste repository

    Full Text Available Presented paper focuses on consideration and evaluation of methodical approaches to analyze cyclical structure character of economic activity in transition economy. As a starting point, work in time domain is applied, which is followed in frequency domain approach. Both approaches are viewed from methodical as well as application point of view and their advantage and disadvantage are discussed. Consequently, time-frequency domain approach is added and applied on real data. On the basis of obtained results recommendation is formulated. All discussed methodical approaches are also considered from the perspective of capability to evaluate behaving of business cycle in time of global economic crisis before/after year 2008. The empirical part of the paper deals with data of gross domestic product in the Czech Republic in 1996/Q1–2010/Q2.

    Full Text Available The aim of this work is to determine whether the accounting information provided by construction and real estate firms in Spain reflects the real economic activity, during upswings and downturns. A relationship is found between economic conditions and financial reporting in a continental European country such as Spain. Although there is a relationship between real housing price growth and financial accounting measures, real estate companies seem to show an artificial position, since they only present a relationship with Return on Assets (ROA based on low quality income (accruals. Therefore, a different financial position influences a different behaviour in these two similar sectors. In fact, some signs alerting of possible risk in real estate firms are shown.

    Full Text Available In this paper, we propose to present a representative set of lines, directions and concrete ways of action that we consider useful and relevant for the economic activity exerted by Romanian entrepreneur in his quality as main actor in the national system of market economy. In other order of ideas we believe that a better understanding of entrepreneurship phenomenon will obviously provide us many significant indications on the determinants of success and business failure. The concepts and ideas presented in this analyzed issue gives us a realistic perspective on how the entrepreneurs succeed to determine and influence the consumers' preferences through the placing on market a variety of new products and services. On this background we can mention that through its specific activities, the entrepreneurship environment is meant to introduce new products and services of superior quality with a significant added value to satisfy at the highest level of customer needs. Thanks to their innovative capacity the entrepreneurs show modern modalities of production and they also identify new markets which have not yet been exploited. Also, through the entrepreneurship activity are discovered and created new business organizations which directly affect the economy. In this context, the creation of new business opportunities through entrepreneurial activity, productivity and innovation lead to economic growth.

  2. The economics of physical activity: societal trends and rationales for interventions.

    2004-10-01

    What are Americans doing with their time and their money and what has changed in recent decades? Do changes suggest interventions that will lead to healthier lifestyles? This paper analyzes several different data sets that reveal some surprising (and some less surprising) insights. The big growth areas, both in terms of expenditure and time allocation, have been leisure time and travel/transportation. Leisure-time industries outpace gross-domestic-product growth for both "active" (sporting goods, dance studios, gyms) and "sedentary" industries (spectator sports, cable TV), although industries associated with more sedentary lifestyles grow the fastest. Overall time spent in productive activities, whether at home or work, has declined by several hours each week for both men and women compared to 40 years ago. Reduced physical activity by itself is not a reason for intervening, as many changes improved overall quality of life (even if not necessarily health-related quality of life). But other trends are more likely to reflect poorly functioning markets, leading to worse economic and health outcomes. Market failures that lead to less physical activity or unhealthy nutrition justify interventions, both from an economic and a public health perspective.

    2012-08-15

    Climate change is one of the major global challenges of our time. There is abundant scientific evidence that the emission of greenhouse gases caused by economic activities contributes to climate change. Accelerating emissions of carbon dioxide, methane, and other greenhouse gases since the beginning of the 20th century have increased the average global temperature by about 0.8C and altered global precipitation patterns. Combustion of fossil fuels, deforestation, but also specific agricultural activities and industrial processes are the main drivers of the increased emission of greenhouse gasses. Enhanced concentrations of greenhouse gasses in the atmosphere will increase global temperatures by radiative forcing. Likewise, climate change has a direct impact on all kinds of economic processes. These impacts may be positive or negative, but it is expected that the overall impact will be primarily negative. In order to design effective mitigation policies, one must have a good conception of the economic driving forces of climate change. The air emission accounts can be used to analyse the environmental implications in terms of greenhouse gas emissions, of production and consumption patterns. Because of their compatibility with the national accounts, greenhouse gas data can be directly linked to the economic drivers of global warming. There are several frameworks for estimating the greenhouse gas emissions for a country, yielding different results. Well-known are the emissions reported to the UNFCCC (United National Framework Convention on Climate Change) in particular under the Kyoto Protocol, but also environment statistics as well as the air emission accounts provide independent greenhouse gas estimates. The differences are not the result of disputes about the accuracy of the estimates themselves, but arise from different interpretations of what has to be counted. The inclusion or exclusion of certain elements depends on the concepts and definitions that underlie

  5. Exercising choice: the economic determinants of physical activity behaviour of an employed population.

    Lack of physical activity is a major contributing factor to the worldwide obesity epidemic, and to the overall burden of disease. The deindustrialisation of developed economies and move to more sedentary employment has impacted on the opportunities of working individuals to participate in physical activity. This can have negative effects on productivity and worker health potentially influencing economic growth. Thus, it is important to determine the factors influencing the frequency of participation in physical activity for employed individuals. This paper uses a modified time allocation framework to explore this issue. We use data from the first six waves of the Household Income and Labour Dynamics of Australia survey (HILDA). The analysis examines frequency of participation in physical activity using a generalised random effects ordered probit model. We control for non-parallel cut-points between the physical activity categories and individual heterogeneity, as well as exploring differences across gender. The results indicate that there is a time trade-off between non-market work, market work, and the frequency of physical activity participation. This effect is moderated by gender. For example, dependent children have a larger negative effect on the frequency of physical activity participation for women. Education and marriage have a larger negative effect on the frequency of participation for men. The findings suggests that policies which make exercise more convenient, and hence decrease the opportunity cost of exercise, will help to encourage more frequent participation in physical activity for working adults.

    With the rapid developments taking place in coal mining technology and due to high investment costs, optimization of the structure of underground coal mines is crucial to the success of the mining project. The structure of a mine, once it is developed, cannot be readily changed and has a decisive influence on the productivity, safety, economics, and production capacity of the mine. The Department of Energy desires to ensure that the resource characterization and planning activity for underground coal mining will focus on those areas that offer the most promise of being advanced. Thus, this project was undertaken by Management Engineers Incorporated to determine the status in all aspects of the resource characterization and planning activities for underground coal mining as presently performed in the industry. The study team conducted a comprehensive computerized literature search and reviewed the results. From this a selection of the particularly relevant sources were annotated and a reference list was prepared, catalogued by resource characterization and mine planning activity. From this data, and discussions with industry representatives, academia, and research groups, private and federal, an assessment and evaluation was made of the state-of-the-art of each element in the resource characterization and mine planning process. The results of this analysis lead to the identifcation of areas requiring research and, specifically, those areas where DOE research efforts may be focused.

    The concept of constructing nuclear power plants on the sea or underground as the future sitting is based on moving the present power plants on the ground with actual results to the sea or underground without changing the design. The underground nuclear power plants have many similar points to underground hydro-electric power stations with many achievements in the construction viewpoint, though they have their proper difficult problems. Of course, it requires to excavate larger underground caves than the case of underground hydro-electric power plants. The maximum dimensions of the caves have been determined through experience in practice. Therefore the developments of design theory and construction technique are desirable in this field. In discussing underground construction, two evaluating methods are considered for the shielding effect of base rocks. The minimum vertical distance up to ground surface from the center of the cave differs depending upon the in-cave pressure, and the conditions of base rock, soil and underground water in case of the accident assumed in the design, and is approximately 60m, if the cave is assumed to be an indefinite cylindrical shape, by the safer side calculation in the above two evaluations.

    Underground laboratories are essential for various important physics areas such as the search for dark matter, double beta decay, neutrino oscillation, and proton decay. At the same time, they are also a very important location for studying rock mechanics, earth structure evolution,and ecology. It is essential for a nation's basic research capability to construct and develop underground laboratories. In the past, China had no high-quality underground laboratory,in particular no deep underground laboratory,so her scientists could not work independently in major fields such as the search for dark matter,but had to collaborate with foreign scientists and share the space of foreign underground laboratories. In 2009, Tsinghua university collaborated with the Ertan Hydropower Development Company to construct an extremely deep underground laboratory, the first in China and currently the deepest in the world, in the Jinping traffic tunnel which was built to develop hydropower from the Yalong River in Sichuan province. This laboratory is named the China Jinping Underground Laboratory (CJPL) and formally opened on December 12, 2010. It is now a major independent platform in China and can host various leading basic research projects. We present a brief review of the development of various international underground laboratories,and especially describe CJPL in detail. (authors)

    2005-11-01

    An update on previous macroeconomic analyses of the impacts of offshore petroleum activities in Newfoundland and Labrador was presented. Details of industry activity and expenditures in Newfoundland and Labrador were presented as well as the resultant direct, indirect and induced economic benefits to the province. Related developments in infrastructure, education, training, and research and development were also provided. It was observed that there was a further consolidation and expansion of the offshore petroleum industry in the province as well as additional growth in its contribution to the province's economy. By 2004, the petroleum industry was responsible for nearly 25 per cent of the province's GDP, with total labour income being 12 per cent higher than it would have been without offshore petroleum industry activity. Significant positive effects were noted in retail sales, the unemployment rate, housing starts and the size of the provincial population. Production activity has become increasingly important, and there has been increased involvement of local companies and individuals in export work, indicating that the petroleum industry is making an important contribution to economic diversification and sustainability. New offshore petroleum activities included the Hebron oilfield project; satellite field developments in the Jeanne d'Arc Basin; exploration in the Orphan Basin and Laurentian Sub-basin; and the development of natural gas reserves using compressed natural gas (CNG) or alternative transportation strategies. Infrastructure, education, training and research and development activities were outlined. It was noted that the low level of exploration in 2003 and 2004 was a matter of concern. It was concluded that a failure to proceed with more recent development projects would be a major blow to the local petroleum industry and the economy as a whole. 2 refs., 2 tabs., 1 fig

Thus, internationalization is seen as a set of strategic methods, techniques and tools necessary to the companies to function abroad. As the effects of – fiscal and monetary – policies on the global demand and supply are unpredictable in time and space, it appears the requirement to substantiate, develop and put into practice a stabilizing strategy. Besides the indexes showing the evolution of the demand and supply, the market can offer economic agents other analysis and decision parameters as well, such as: economic and financial instruments for influencing the behaviour of the business environment.Obviously, the results depend also on how the authorities (legislative and executive, central and local work for a friendly business environment.

    The first nuclear test agreement, the test moratorium, was made in 1958 and lasted until the Soviet Union unilaterally resumed testing in the atmosphere in 1961. It was followed by the Limited Test Ban Treaty of 1963, which prohibited nuclear tests in the atmosphere, in outer space, and underwater. In 1974 the Threshold Test Ban Treaty (TTBT) was signed, limiting underground tests after March 1976 to a maximum yield of 250 kt. The TTBT was followed by a treaty limiting peaceful nuclear explosions and both the United States and the Soviet Union claim to be abiding by the 150-kt yield limit. A comprehensive test ban treaty (CTBT), prohibiting all testing of nuclear weapons, has also been discussed. However, a verifiable CTBT is a contradiction in terms. No monitoring technology can offer absolute assurance that very-low-yield illicit explosions have not occurred. The verification process, evasion opportunities, and cavity decoupling are discussed in this paper

    Multiple studies have yielded remarkably consistent results relating radon daughter exposure to lung cancer risk in underground mining populations. The U.S. uranium miner study appears to be at variance with the other results. The primary reason is that the doses in the U.S. miner study were systematically overestimated, resulting in a risk coefficient that is lower than all the others. The significance of these findings for radiogenic lung cancer goes well beyond mining populations, because one is now aware of the implications of radon daughters detected in homes. The highest cumulative levels from radon exposures within homes have been found in Sweden, evidently because of their unusual geology with uranium-bearing ores near the surface. The Swedish authorities view this as a major public health problem that needs to be addressed

In front of the reaction of public opinion relative to the nuclear waste question, it was essential to begin by a study on the notions of liability, transparence and democracy. At the beginning, it was a matter of underground researches with a view to doing an eventual storage of high level radioactive wastes. The Parliament had to define, through the law, a behaviour able to come to the fore for anybody. A behaviour which won recognition from authorities, from scientists, from industrial people, which guarantees the rights of populations confronted to a problem whom they were not informed, on which they received only few explanations.

    Numerical modeling techniques were used to determine the conditions required for seismic waves generated by an earthquake to cause instability to an underground opening or create fracturing and joint movement that would lead to an increase in the permeability of the rock mass. Three different rock types (salt, granite, and shale) were considered as host media for the repository located at a depth of 600 m. Special material models were developed to account for the nonlinear material behavior of each rock type. The sensitivity analysis included variations in the in situ stress ratio, joint geometry, and pore pressures, and the presence or absence of large fractures. Three different sets of earthquake motions were used to excite the rock mass. The methodology applied was found to be suitable for studying the effects of earthquakes on underground openings. In general, the study showed that moderate earthquakes (up to 0.41 g) did not cause instability of the tunnel or major fracturing of the rock mass; however, a tremor with accelerations up to 0.95 g was amplified around the tunnel, and fracturing occurred as a result of the seismic loading in salt and granite. In situ stress is a critical parameter in determining the subsurface effects of earthquakes but is nonexistent in evaluating the cause for surface damage. In shale with the properties assumed, even the moderate seismic load resulted in tunnel instability. These studies are all generic in nature and do not abrogate the need for site and design studies for specific facilities. 30 references, 14 figures, 8 tables

    To examine the relationship between physical activity stages of change and preferences for financial risk and time. A cross-sectional, community-based study. A low-income, urban, African-American neighborhood. One hundred sixty-nine adults. Self-reported physical activity stages of change-precontemplation to maintenance, objectively measured body mass index and waist circumference, and economic preferences for time and risk measured via incentivized economic experiments. Multivariable ordered logistic regression models were used to examine the association between physical activity stages of change and economic preferences while controlling for demographic characteristics of the individuals. Individuals who are more tolerant of financial risks (odds ratio [OR] = 1.31, p < .05) and whose time preferences indicate more patience (OR = 1.68, p < .01) are more likely to be in a more advanced physical activity stage (e.g., from preparation to action). The likelihood of being in the maintenance stage increases by 5.6 and 10.9 percentage points for each one-unit increase in financial risk tolerance or one-unit increase in the time preference measure, respectively. Greater tolerance of financial risk and more patient time preferences among this low-income ethnic minority population are associated with a more advanced physical activity stage. Further exploration is clearly warranted in larger and more representative samples.

    Full Text Available The article considers the concept of “outsourcing”, “economic safety’, “cluster formation”. Outsourcing is defined as external influences that contribute to the effective operation of the enterprise. The economic essence of "outsourcing" in the research and domestic practice, which has hitherto manifested itself only as a method of attracting temporary workers in the field. On the example of the dairy industry is studied safe operation as sustainable, and competitive Bozrikova their behavior with regard to outsourcing. Studied the differences of the processes of cooperation, subcontracting and clustering. Stated that cooperation and subcontracting are the component parts outsourcing, which covers the process of production or provision of services; the outsourcing justifies: the transfer of technical functions or business processes, and thus part of the risks transferred to the outsourcing provider. An example of adaptive modeling outsourcing, suggesting that in the future, the projected volume of production, processing and sales of dairy products manufactured by the enterprises of dairy industry of the Voronezh region belonging to a cluster will be reduced through the introduction of a mechanism of outsourcing. It proves that the risk of bankruptcy of enterprises on the basis of adaptive models. The application of the mechanism of outsourcing in order to increase the economic security, in particular, such of its functions as the transmission of external organizations not only certain social functions (such as the use of temporary workers, but also the activities of the business processes to optimize all kinds of resources and concentration of efforts on the core activities of each company within the cluster APK. Analysis conducted by the authors suggests: in the future, the projected volume of production, processing and sales of dairy products manufactured by the enterprises of agriculture, dairy production and trade of the Voronezh

    The mining-related damages such as ground subsidence, acid mine drainage (AMD), and deforestation in the abandoned underground coal mine areas become an object of public concern. Therefore, the system to manage the mining-related damages is needed for the effective drive of rehabilitation activities. The management system for Abandoned Underground Coal Mine using GIS includes the database about mining record and information associated with the mining-related damages and application programs to support mine damage prevention business. Also, this system would support decision-making policy for rehabilitation and provide basic geological data for regional construction works in abandoned underground coal mine areas. (authors)

  10. CO2 emissions and economic activity: Short- and long-run economic determinants of scale, energy intensity and carbon intensity

    Andersson, Fredrik N.G.; Karpestam, Peter

    2013-01-01

    We analyze the short-term and the long-term determinants of energy intensity, carbon intensity and scale effects for eight developed economies and two emerging economies from 1973 to 2007. Our results show that there is a difference between the short-term and the long-term results and that climate policy are more likely to affect emission over the long-term than over the short-term. Climate policies should therefore be aimed at a time horizon of at least 8 years and year-on-year changes in emissions contains little information about the trend path of emissions. In the long-run capital accumulation is the main driver of emissions. Productivity growth reduces the energy intensity while the real oil price reduces both the energy intensity and the carbon intensity. The real oil price effect suggests that a global carbon tax is an important policy tool to reduce emissions, but our results also suggest that a carbon tax is likely to be insufficient decouple emission from economic growth. Such a decoupling is likely to require a structural transformation of the economy. The key policy challenge is thus to build new economic structures where investments in green technologies are more profitable. - Highlights: • We model determinants of scale, energy intensity and carbon intensity. • Using band spectrum regressions, we separate between short and long run effects. • Different economic variables affect emission in the short and long run. • CO 2 reducing policies should have a long run horizon of (at least 8 years). • A low carbon society requires a structural transformation of the economy

    2016-01-01

    The aim of this work is to analyze the spatial distribution of potential pollution pathways of water resources given the economic activity in the Mexican border state of Sonora and propose a regional distribution in relation to cancer mortality rates across the state. The methodology is based in an exploratory and inferential data analysis using two sources of primary data: wastewater discharge concessions registered in the Public Registry on Water Rights [Registro Público de Derechos de Agua] (REPDA) and the records generated by the National Health Information System [Sistema Nacional de Información en Salud] (SINAIS) in the period 1998-2011 based on the International Classification of Disease (ICD-10). The spatial concentration analysis allows for the identification of specific cancer mortality causes at the regional level. Results indicate that the projected adjustments to the regulation NOM-250-SSA1-2014, which controls a subset of pollutants common in mining activity surroundings, is a matter of regional concern.

    Recently, the Los Alamos National Laboratory has proposed two major new initiatives in underground science. Following the dissolution of the original gallium solar neutrino collaboration, Los Alamos has formed a new North American collaboration. We briefly review the rationale for solar neutrino research, outline the proposal and new Monte Carlo simulations, and describe the candidate locations for the experiment. Because there is no dedicated deep underground site in North America suitable for a wide range of experiments, Los Alamos has conducted a survey of possible sites and developed a proposal to create a new National Underground Science Facility. This paper also reviews that proposal

    Does water has an age? The age of underground waters can be the duration of their underground travel between their infiltration inside the ground and their captation at a spring or a drilled well. The isotopic geochemistry comes to the support of classical geochemistry to estimate these residence times. Radio-isotopes, like tritium for young waters or carbon 14 for old waters, are used as chronometers to interpret the recharge ways, the flow mechanisms and the residence times of underground waters. Their use is presented in this article with some theoretical recalls and some examples of application. (J.S.)

  18. The Legality of Foreign Military Activities in the Exclusive Economic Zone under UNCLOS

    2012-02-01

    Full Text Available During negotiations for the United Nations Convention on the Law of the Sea (UNCLOS, military activities in another state's Exclusive Economic Zone (EEZ were a point of contention. Currently, the issue remains controversial in state practice. UNCLOS attempts to balance the differing interests of coastal and maritime states, but is silent or ambiguous on the legality of military operations in foreign EEZs. Coastal states seek to assert increasing control over their maritime zones while maritime states prioritize the freedom of navigation. This article examines the competing views on these issues in the context of the 2009 Impeccable incident between China and the United States that occurred in the South China Sea. The issue of military activities in the EEZ will continue to be a complex subject, without clear definitions in the nature and scope of permissible activity. As state practice evolves, the potential for hostilities is high, particularly in semi-enclosed sea areas such as the South China Sea. This article concludes that states should create dialogues and form agreements to help clarify the contours of military activity in the EEZ, focusing on mutual interests, interdependence, and coexistence rather than perceiving the ocean as a zero-sum resource.

    Full Text Available The research deals with the topic of the analysis of venture capital funds’ rate of return on venture activity. The discovered venture capital funds have such a peculiarity as the involved investors of various types and concentrated financial resources, which lead to advantages in investing. Based on the analyzed scientific approaches to the evaluation of income rate met by various economic entities the paper determines the optimal indicators of such an analysis developed due to the article research. They are supposed to improve significantly the process of making decisions on venture capital investments. The author suggests to evaluate venture capital funds rate of return on venture activity by means of the basic four indicators usually employed for investment efficiency definition: net profit, internal rate of return, return period and return index. The research presents the examination of rates of return on venture activity of venture capital funds being controlled by a single asset management company. Thus, one can estimate not only the rate of return on venture activity, but also the efficiency of control taken by an asset management company.

    Little is known about associations of adolescents' socio-economic status (SES) and their sexual activity and risk behaviours. This study examined these associations in Nova Scotia adolescents aged 15-19. Students at four high schools in northern Nova Scotia completed surveys examining relationships of family SES factors and: 1) sexual activity (having had vaginal or anal intercourse, intercourse before age 15 (early intercourse)); and 2) risk behaviours (use of contraception/condoms, number of partners and unplanned intercourse after substance use). Of students present when the survey was administered, 2,135 (91%) responded. Almost half (49%) had had vaginal intercourse, and 7% anal intercourse. In univariate analysis for young women, non-intact family structure and lower parental education were associated with having vaginal, anal and early intercourse. Female risk behaviours showed no significant univariate associations with SES. Young men had univariate associations of family structure, lower maternal education and paternal unemployment with early intercourse, and lower paternal education with anal intercourse. Condom use was higher for young men with employed fathers; those living with both parents less often had >1 sexual partner. In multivariate analysis, most SES associations with females' sexual activities held, while most for males did not, and few associations of SES and risk behaviours were seen for females. Indicators of lower SES are associated with sexual activity in young women. Sexual risk behaviours are not often associated with SES in females, though they are more so in males. These findings have implications for sexual health promotion and health services.

  1. Sociocultural Factors of Survival of Males and Females in Economically Active Age: a Regional Analysis

    2018-03-01

    Full Text Available The period, when a person starts and completes his or her professional carrier and labour participation, in general, coincides with the age when the self-preservation behaviour develops. It is a time when a person aims for a healthy and safe lifestyle. During this period, an individual assumes the main standards, values of the self-preservation behaviour inherent in an ethnic, social and cultural macro-environment. To research the sociocultural factors of survival, we applied econometric modelling to demographic processes using the discrete and probabilistic indicators of the mortality tables of male and female in economically active age. The econometric model included the elements of spatiotemporal characteristics of territories. These characteristics are interrelated with the indicators of survival probability and the indicator of average life expectancy in the regions of Russia. We choose the major sociocultural factors by the correlation ratio of indicators and their sensitivity. The econometric analysis has revealed a high degree of sensitivity of a territorial variation of demographic and sociocultural factors in the regions of Russia, including a gender aspect. The most significant socio-economic factors, which determine the self-preservation behaviour of males, are the following: 1 the size of Gross Regional Product per capita; 2 quality of health infrastructure; 3 fixed investments; 4 population with monetary income under the subsistence minimum (share coefficient of income differentials. The female have the same hierarchy of socio-economic factors, except for the sensitivity of variables to the regional differentiation of signs. The household poverty factor has little significance for the women and it is the main difference between male and female. The built model has shown the predictive importance in the assessment of the above-mentioned factors in short and medium-term prospects.

    Emanuelli, M.; Federico, G.; Loughman, J.; Prasad, D.; Chow, T.; Rathnasabapathy, M.

    2014-11-01

    It has become increasingly clear in recent years that the issue of space debris, particularly in low-Earth orbit, can no longer be ignored or simply mitigated. Orbital debris currently threatens safe space flight for both satellites and humans aboard the International Space Station. Additionally, orbital debris might impact Earth upon re-entry, endangering human lives and damaging the environment with toxic materials. In summary, orbital debris seriously jeopardizes the future not only of human presence in space, but also of human safety on Earth. While international efforts to mitigate the current situation and limit the creation of new debris are useful, recent studies predicting debris evolution have indicated that these will not be enough to ensure humanity's access to and use of the near-Earth environment in the long-term. Rather, active debris removal (ADR) must be pursued if we are to continue benefiting from and conducting space activities. While the concept of ADR is not new, it has not yet been implemented. This is not just because of the technical feasibility of such a scheme, but also because of the host of economic, legal/regulatory, and political issues associated with debris remediation. The costs of ADR are not insignificant and, in today's restrictive fiscal climate, are unlikely/to be covered by any single actor. Similarly, ADR concepts bring up many unresolved questions about liability, the protection of proprietary information, safety, and standards. In addition, because of the dual use nature of ADR technologies, any venture will necessarily require political considerations. Despite the many unanswered questions surrounding ADR, it is an endeavor worth pursuing if we are to continue relying on space activities for a variety of critical daily needs and services. Moreover, we cannot ignore the environmental implications that an unsustainable use of space will imply for life on Earth in the long run. This paper aims to explore some of these

  4. Impacts of climatic change on water and associated economic activities in the Swiss Alps

    Science.gov (United States)

    Beniston, Martin

    2012-01-01

    SummaryThe European Alps are one region of the world where climate-driven changes are already perceptible, as exemplified by the general retreat of mountain glaciers over past decades. Temperatures have risen by up to 2 °C since 1900 particularly at high elevations, a rate that is roughly three times the global-average 20th century warming. Regional climate models suggest that by 2100, winters in Switzerland may warm by 3-5 °C and summers by 6-7 °C according to greenhouse-gas emissions scenarios, while precipitation is projected to increase in winter and sharply decrease in summer. The impacts of these levels of climatic change will affect both the natural environment and a number of economic activities. Alpine glaciers may lose between 50% and 90% of their current volume and the average snowline will rise by 150 m for each degree of warming. Hydrological systems will respond in quantity and seasonality to changing precipitation patterns and to the timing of snow-melt in the Alps, with a greater risk of flooding during the spring and droughts in summer and fall. The direct and indirect impacts of a warming climate will affect key economic sectors such as tourism, hydropower, agriculture and the insurance industry that will be confronted to more frequent natural disasters. This paper will thus provide an overview of the current state of knowledge on climatic change and its impacts on the Alpine world.

  5. Underground storage of natural gas in Italy

    Henking, E.

    1992-01-01

    After first relating the importance of natural gas storage to the viability of Italian industrial activities, this paper discusses the geo-physical nature of different types of underground cavities which can be used for natural gas storage. These include depleted petroleum and natural gas reservoirs, aquifers and abandoned mines. Attention is given to the geologic characteristics and physical characteristics such as porosity, permeability and pressure that determine the suitability of any given storage area, and to the techniques used to resolve problems relative to partially depleted reservoirs, e.g., the presence of oil, water and salt. A review is made of Italy's main storage facilities. This review identifies the various types of storage techniques, major equipment, operating and maintenance practices. A look is then given at Italy's plans for the development of new facilities to meet rising demand expected to reach 80 billion cubic meters/year by the turn of the century. The operating activities of the two leading participants, SNAM and AGIP, in Italy's natural gas industry are highlighted. Specific problems which contribute to the high operating costs of natural gas storage are identified and a review is made of national normatives governing gas storage. The report comes complete with a glossary of the relative terminology and units of measure

    Lollivier, S

    1984-06-01

    This study uses data from tax declarations for 40,000 French households for 1975 to propose a model that permits quantification of the effects of certain significant factors on the economic activity of married women. The PROBIT model of analysis of variance was used to determine the specific effect of several variables, including age of the woman, number of children under 25 years of age in the household, the age of the youngest child, husband's income and socioprofessional status, wife's level and type of education, size of community of residence and region of residence. The principal factors influencing activity rates were found to be educational level, age, and to those of childless women, but activity rates dropped by about 30% for mothers of 2 and even more for mothers of 3 or more children. Influence of the place of residence and the husband's income were associated with lesser disparities. The reasons for variations in female labor force participation can be viewed as analogous to a balance. Underlying factors can increase or decrease the income the woman hopes to earn (offered income) as well as the minimum income for which she will work (required salary). A TOBIT model was constructed in which income was a function of age, education, geographic location, and number of children, and salary required was a function of the variables related to the husband including income and socioprofessional status. For most of the effects considered, the observed variation in activity rates resulted from variations in offered income. The husband's income influences only the desired salary. The offered income decreases and the required salary increases when the number of children is 2 or more, reducing the rate of activity. More educated women have slightly greater salary expectations, but command much higher salaries, resulting in an increased rate of professional activity.

    This study of radionuclide behavior at underground environment has been carried out as a part of the study of high-level waste disposal technology development. Therefore, the main objectives of this project are constructing a data-base and producing data for the safety assessment of a high-level radioactive waste, and verification of the objectivity of the assessment through characterization of the geochemical processes and experimental validation of the radionuclide migration. This project is composed of 6 subjects such as data production required for safety assessments, sorption properties and mechanisms, nuclide migration in the fractured rock, colloid formation and migration, nuclide speciation in deep geological environments, and total evaluation of geochemical behaviors considering multi-factors. The various results from the this project can be applicable to the preliminary safety and performance assessments of the established disposal concept for a future high-level radioactive waste repository. Providing required data and technical basis for assessment methodologies could be a direct application of the results. In a long-term view, the results can also be utilized as a technical background for the establishment of government policy for high-level radioactive waste disposal

    Layout of underground structure has to be designed based on rock mechanical analysis and the concept of active support has to be adopted considering the large openings are requested to accommodate heavy duty diesel equipment in underground. Rock bolt and shotcrete will be the most applicable method to support such a large dimensional tunnels. 1) Direction: The main haulage way of the mines where diesel equipment are operating is ramp way system. For optimizing safety measures, and minimizing maintenance cost of the tunnels, it is strongly recommended that all the tunnels including ramp way, rooms and sublevels should be designed in parallel to the direction of principal stress and perpendicular to the direction of major discontinuity. 2) Inclination: Basically, the inclination of the ramp way depends on the specification of the equipment, but 10-15% is usual. The steep inclination needs less initial investment but there will be an adverse effects such as higher operating and maintenance costs. 3) Profile (Cross section): The maximum dimension of the equipment operating in local mines appeared 12.8m long, 3.705m wide and 3.68m high. Considering the dimension, the requested profile simply can be calculated to 4m x 4m, but it should be decided according to the regulated minimum clearances from the walls and roof. The minimum inner curvature radius of the tunnels should be more than 5.2m, and in this case, the tunnel width of the curved zone should be more than 5.5m. 4) Sight distance and braking distance: For the safe operation of the equipment, the sight distance must be longer than braking distance, so that the driver can hold up the equipment safely after finding the obstacles in front of him. The maximum braking distance without heating of brake shoe is 60m. 5) Support and maintenance: Due to the large dimensional tunnels where diesel equipment are operating, the conventional supporting system is not applicable. Therefore, the active support concept should be

    Infection with bovine viral diarrhea virus (BVDV) results in major economic losses either directly through decreased productive performance in cattle herds or indirectly, such as through expenses for control programs. The aim of this systematic review was to review financial and/or economic assessment studies of prevention and/or mitigation activities of BVDV at national, regional and farm level worldwide. Once all predefined criteria had been met, 35 articles were included for this systematic review. Studies were analyzed with particular focus on the type of financially and/or economically-assessed prevention and/or mitigation activities. Due to the wide range of possible prevention and/or mitigation activities, these activities were grouped into five categories: i) control and/or eradication programs, ii) monitoring or surveillance, iii) prevention, iv) vaccination and v) individual culling, control and testing strategies. Additionally, the studies were analyzed according to economically-related variables such as efficiency, costs or benefits of prevention and/or mitigation activities, the applied financial and/or economic and statistical methods, the payers of prevention and/or mitigation activities, the assessed production systems, and the countries for which such evaluations are available. Financial and/or economic assessments performed in Europe were dominated by those from the United Kingdom, which assessed mostly vaccination strategies, and Norway which primarily carried out assessments in the area of control and eradication programs; whereas among non-European countries the United States carried out the majority of financial and/or economic assessments in the area of individual culling, control and testing. More than half of all studies provided an efficiency calculation of prevention and/or mitigation activities and demonstrated whether the inherent costs of implemented activities were or were not justified. The dairy sector was three times more likely to

    Directory of Open Access Journals (Sweden)

    Giacomo D’Alisa

    2015-07-01

    Full Text Available In the current economic crisis of industrialized society, social movements face two types of challenges: firstly, they are confronting institutions that are less capable of and have no propensity for mediating new socio-economic demands; secondly, they are experiencing difficulties in building strong and lasting bonds of solidarity and cooperation among people. The latter are fundamental resources for the emergence of collective action; however, the highly individualized structure of contemporary society makes the creation of social ties ever the more difficult. As a consequence, contemporary waves of protest are often short-lived. Nonetheless, in response to the multidimensional crises, the consolidation of grassroots mutualistic and cooperative experiences, within which new affiliations for collective action are experienced, is on the rise. Indeed, it is a fact that even though conditions are not favorable, social movements have continued to ex-pand and promote community-led initiatives for social and economic sustainability. In some cases, these initiatives play a decisive role in the fight against poverty and in guaranteeing human livelihood. Solidarity-based exchanges and networks, such as barter groups, urban gardening, new consumer-producer networks and cooperatives, time banks, local savings groups, urban squatting, and others similar experiences are typical examples of continuous reactivation of people's desire to be agents of their own destiny. This combination of formal and informal networks are a testimony to an ability and an aspiration. Indeed, on one hand, they are indicative of citizens' capacity to self-organize in order to tolerate, absorb, cope with and adjust to the environmental and social threats posed by neoliberal policies. On the other hand, they are attempting to change an economic system, increasingly perceived as unfair and ecological disruptive, by building an alternative in the cracks of the former, based on greater

  3. ETHICS AND ORGANIZATIONAL CULTURE – KEY ELEMENTS REGARDING THE DEVELOPMENT OF ECONOMIC ACTIVITIES

    Directory of Open Access Journals (Sweden)

    Loredana TEREC-VLAD

    2016-02-01

    Full Text Available The aim of this paper is to analyse the organizational culture within the business environment. The paper analyzes the ethical criteria of the entrepreneurs and the way they relate to the consumer, as well as the reinforcement of the moral values so that the final result of the economic activity is represented by sustainability and economic profit. We thought it would be important to point out that promoting an ethical firm can ensure the well-needed trust capital in a constantly changing society. In this context, corporate responsibility is a key element that ensures both the sustainability of the company as well as the sustainability of the relations with the business partners. In our view, a strong corporate culture must integrate ethics and responsibility in all its activities, since the focus is often laid on obtaining profit, not on the values ​​that should lead the organization towards success over a long period of time. Since our society provides both positive and negative information regarding any company or organization, the focus should be laid increasingly more on the ethics and responsibility of the human resources in regard to the external environment of the company. We thought it would be appropriate to bring up these issues since the issue of building an organizational culture is at a very early stage in our country, and most entrepreneurs only aim at obtaining short-term profit. The fees and taxes are high and the thick legislation often does not provide alternatives; therefore, one must take into account the fact that the real profit is not represented by the short-term benefits, but rather by the benefits obtained in a constant manner over medium-long periods of time.

  4. Utility experiences in redevelopment of formerly used sites -- Wisconsin Electric's risk management and economic development activities

    1999-01-01

    Wisconsin Electric Power Company, which recently celebrated its 100th anniversary, has actively promoted the redevelopment of its former sites as well as those of its customers. Serving Milwaukee and southeast Wisconsin, Wisconsin Electric's (WE) sites include former power plants, landfills, right-of-ways, and manufactured gas plant sites. In setting an example for others, as well as seeking to maximize the economic value of these sites, WE has either redeveloped or promoted the redevelopment of these sites by others. Examples include the East Wells Power Plant (now home of the Milwaukee Repertory Theater), the Lakeside Power Plant Site (now the home of Harnischfeger Corporation's headquarters), and the Commerce Street Power Plant located on the Milwaukee River near downtown Milwaukee. In each case the company evaluated the potential environmental liabilities against the unrealized asset value derived from facility location, site size, architectural uniqueness, or other characteristics. At the Commerce Street Power Plant, walking distance to the downtown Milwaukee business district combined with river frontage, were significant site values leveraged against a $5 million asbestos and lead-based paint removal project done to prepare the plant for marketing. More recently, WE has used its experience in promoting the redevelopment of the Menomonee River Valley, the original core of Milwaukee's industrial community, and in advancing a more practical regulatory approach to redeveloping older sites. Finally, the company is working with a non-profit community health clinic, community groups and local foundations in linking these redevelopment activities with the economic and physical health of inner city residents

    Many regulatory activities for preservation of the environment make it recently difficult for the stone industry in our country. To reduce environmental hazards and to conserve original surface and woods, some effective underground methods must be adopted. Some new techniques such as chain saw machine, diamond wire saw and water jet cutting can be considered. But application of chain saw machine for underground quarry is proposed in this study. Some technical adoptions with chain saw were carried out at Jungseun marble mine. It is proved that this machine can be effectively adopted to cut dimension stone. With chain saw and diamond wire saw, it can be expected to achieve more effectively cutting the dimension stone. (author). 6 refs., 3 tabs., 6 figs.

    2011-01-25

    Estimating effects due to an urban IND (improvised nuclear device) on underground structures and underground utilities is a challenging task. Nuclear effects tests performed at the Nevada Test Site (NTS) during the era of nuclear weapons testing provides much information on how underground military structures respond. Transferring this knowledge to answer questions about the urban civilian environment is needed to help plan responses to IND scenarios. Explosions just above the ground surface can only couple a small fraction of the blast energy into an underground shock. The various forms of nuclear radiation have limited penetration into the ground. While the shock transmitted into the ground carries only a small fraction of the blast energy, peak stresses are generally higher and peak ground displacement is lower than in the air blast. While underground military structures are often designed to resist stresses substantially higher than due to the overlying rocks and soils (overburden), civilian structures such as subways and tunnels would generally only need to resist overburden conditions with a suitable safety factor. Just as we expect the buildings themselves to channel and shield air blast above ground, basements and other underground openings as well as changes of geology will channel and shield the underground shock wave. While a weaker shock is expected in an urban environment, small displacements on very close-by faults, and more likely, soils being displaced past building foundations where utility lines enter could readily damaged or disable these services. Immediately near an explosion, the blast can 'liquefy' a saturated soil creating a quicksand-like condition for a period of time. We extrapolate the nuclear effects experience to a Chicago-based scenario. We consider the TARP (Tunnel and Reservoir Project) and subway system and the underground lifeline (electric, gas, water, etc) system and provide guidance for planning this scenario.

    Increasing physical activity among children is a potentially important public health intervention. Quantifying the economic and health effects of the intervention would help decision makers understand its impact and priority. Using a computational simulation model that we developed to represent all US children ages 8-11 years, we estimated that maintaining the current physical activity levels (only 31.9 percent of children get twenty-five minutes of high-calorie-burning physical activity three times a week) would result each year in a net present value of $1.1 trillion in direct medical costs and $1.7 trillion in lost productivity over the course of their lifetimes. If 50 percent of children would exercise, the number of obese and overweight youth would decrease by 4.18 percent, averting $8.1 billion in direct medical costs and $13.8 billion in lost productivity. Increasing the proportion of children who exercised to 75 percent would avert $16.6 billion and $23.6 billion, respectively. Project HOPE—The People-to-People Health Foundation, Inc.

    Generally speaking, the creation of tariff systems for energy activities carried out as regulated or public service obligation is becoming professionally challenging. The Croatian Energy Regulatory Agency (CERA) created the methodology of the tariff system for thermal energy activities and passed this tariff system (without tariff element amounts) in May 2006. The background of the tariff system for thermal energy activities (heat generation, heat distribution and heat supply) including a legislative framework relevant for passing the tariff system, terminology, matrix of the tariff models, tariff elements and amounts of tariff entries are analyzed in this paper. Special attention is paid to the economic characteristics of the tariff system, such as the capital asset pricing model (CAPM), which is chosen among several models of the weighted average of cost of capital (WACC). Using the WACC, the regulatory authorities ensure returns to be equal to the opportunity cost of capital.

  17. FESTIVALS AS CULTURAL ACTIVITIES – COMBINATIONS OF ECONOMIC AND SOCIAL BENEFITS

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available In the latest years, academics have talked more and more about the creative economy, as a cause of a different classification and division of the economic activities, including in its area all those activities which are based on the human resource, its talent and intellectual capital. The creativity seems to be a too special feature, having its own ways to flourish and to be exploited, so it has to be treated separately from the sectors of manufacture, industry or services. The Romanian culture is transmitted and exploited in various ways, starting with the commercialisation of handicrafts and ending with the organisation of events with artistic or symbolic expression. We will focus on the performing arts, organized as events for different communities. These events appear as leisure activities and have an important social feature because they have the attribute to develop the sense of identity, belonging to the group and social cohesion. These aspects are crucial for the development of a creative habitat or cultural center. The festivals attract people for different reasons; some of them are looking for an environment where to socialise, others come being interested exactly in enjoying the event or the specific goods and services which are offered there. Another type of the festival consumers is represented by the ones who only look for something new to experiment, exploring the unknown, this segment not representing loyal customers, but whatever the reason are, each participant comes for the emotional stimulation offered by the enjoyment of the festival.

    Full Text Available Evaluation of the reliability of enterprises engaged in the foreign economic activity and simplifying of Customs procedures have become a relevant issue in the context of globalization. The capabilities and preferences of the “Authorized Economic Operator” status are the cause of a new challenge for managers of enterprises – creation of an internal control system to ensure a systematic monitoring of the conditions of Customs compliance standards of reliability and safety, which would allow identifying risks of loss of the “Authorized Economic Operator” status. The purpose of the scientific paper is to improve the internal control system of an enterprise engaged in foreign economic activity in the process of obtaining and saving the “Authorized Economic Operator” status in accordance with the international Custom requirements for safety and reliability. Methodology. The research is based on the methods of logical and analytical modelling of the impact assessment of individual factors on the value of the generalization indicator. The results are tested on the internal accounting data of the existing machine-building enterprises. Results. The paper shows the results of adapting the concept of COSO to the system of internal control of the foreign economic activity of the enterprise in the process of obtaining or retaining the “Authorized Economic Operator” status. The internal control system within the concept of COSO should ensure the achievement of the objectives – operations, reporting, and compliance. The criteria for estimating the objective “compliance” for an enterprise engaged in foreign economic activity can be an integral indicator of compliance. Value/originality. It is suggested to perform internal control of an enterprise’s compliance with Customs requirements based on the analysis of deviations of the compliance integral indicator. Practical implications. The result of control is to perform a steady in

    Full Text Available The necessity of recognition and optimal exploitation of underground water sources results from the fact that these resources contribute to 99% of total useable soft water of the world. In our country the agricultural sector is the main user of water among different economic sectors. Therefore, applying scientific and appropriate management measures and approaches for desired utilization of this production factor is critical. Taking into account of real value of water in water management of agricultural sector can lead to development of motivation required for saving its usage and also helps  its optimal allocation in production. Generally, water has two types of real prices. One is supplier (producer point of view and the second includes demander perspective. In this study, real price of water from producer and demander point of views was determined by the use of production function approach for wheat production at underground water sources (wells of Damghan. The required data were collected from 184 farmers of Damghan in agricultural year 2007-08. According to superior production function(Generalized Quadratic, economic value of water in wheat production is 403.2 Iranian rials and this is more than the usual value in the area

    1995-12-31

    Good roads are essential in moving men and materials to and from the underground workplace. An underground coal industry funded project was recently completed on underground mine road construction and maintenance. This paper discusses practical approaches to construction and maintenance of underground mine roads using transferable civil technologies and innovative techniques. Mine pavements are generally low-cost (relative to civil roads), constructed to varying standards using locally available materials to best meet the mobility needs of the mine. Performance of pavements is thus largely dependent on the environmental conditions, quality of the available road making materials, maintenance policies and available resources. This paper explains the causes of bad roads in various underground environments. It details available management strategies, construction and water control techniques, road maintenance and vehicle considerations. It concludes that the trend to larger rubber tires mining equipment needs to be matched with construction and maintenance of high quality road surfaces. For large operations, the total cost due to poor roads may equate to in excess of $A1 million per annum. The strategies outlined in this paper provide the basis for construction and maintenance of underground mine roads to help achieve desired production targets. (author). 2 tabs., 4 figs., 7 refs.

    2010-01-01

    Underground coal gasification has potential in Alberta. This presentation provided background information on underground coal gasification and discussed groundwater and the Laurus Energy demonstration project. A multi-disciplined approach to project assessment was described with particular reference to geologic and hydrogeologic setting; geologic mapping; and a hydrogeologic numerical model. Underground coal gasification involves the conversion of coal into synthesis gas or syngas. It can be applied to mined coal at the surface or applied to non-mined coal seams using injection and production wells. Underground coal gasification can effect groundwater as the rate of water influx into the coal seams influences the quality and composition of the syngas. Byproducts created include heat as well as water with dissolved concentrations of ammonia, phenols, salts, polyaromatic hydrocarbons, and liquid organic products from the pyrolysis of coal. A process overview of underground coal gasification was also illustrated. It was concluded that underground coal gasification has the potential in Alberta and risks to groundwater could be minimized by a properly designed project. refs., figs.

    This paper presents the design and installation of an underground ventilation remote monitoring and control system at the Waste Isolation Pilot Plant. This facility is designed to demonstrate safe underground disposal of U.S. defense generated transuranic nuclear waste. To improve the operability of the ventilation system, an underground remote monitoring and control system was designed and installed. The system consists of 15 air velocity sensors and 8 differential pressure sensors strategically located throughout the underground facility providing real-time data regarding the status of the ventilation system. In addition, a control system was installed on the main underground air regulators. The regulator control system gives indication of the regulator position and can be controlled either locally or remotely. The sensor output is displayed locally and at a central surface location through the site-wide Central Monitoring System (CMS). The CMS operator can review all sensor data and can remotely operate the main underground regulators. Furthermore, the Virtual Address Extension (VAX) network allows the ventilation engineer to retrieve real-time ventilation data on his personal computer located in his workstation. This paper describes the types of sensors selected, the installation of the instrumentation, and the initial operation of the remote monitoring system

    The aim of this work is to present the activities related to the determination of radon and progeny concentrations in underground mines in Brazil. Radon is originated from decay of radium-226 and radium-228 present in rocks. Radon and its short-lived progeny can be retained in the workers pulmonary alveoli, and this way they bring about cancer risk to these mining professionals. The occurrence of high radon concentrations in underground coal and copper mines and the lack of systematic survey motivated CNEN, the regulatory agency, to develop the Radon Project, aiming to aid the formulation of a specific regulation with occupational dose limits consistent with international standards recommended by the International Atomic Energy Agency (IAEA). Dozens of underground mines are currently in operation in the national. It had to be noted that about 50% of these mines are located in Minas Gerais province, and for this reason it was chosen to start the Project. In each underground mine it is installed in selected points passive nuclear track etch radon detectors, type LEXAN and Cr-39, for periods from three to five months. It was also made local measurements with Dose Man Pro detectors from SARAD. The points are chosen according to geological features, radiometric activity and characteristics of prospect development. The determination of radon present in mines has been made in IEN (Nuclear Engineering Institute)/Rio de Janeiro-RJ, LAPOC (Pocos de Caldas Laboratory)/Pocos de Caldas-MG e ESPOA (Porto Alegre Office)/Porto Alegre-RS. Until now it was visited about 35 mines in a universe of about 50 mines, from which 20% showed concentration values higher than international limits (ICRP 65), between 500 and 1500 Bq.m -3 .

    Data from Hong Kong were used to examine how the demand for children is affected by the economic returns to different types of market activities. The specific data used was a 1% sample of the 1976 "Hong Kong By-Census of Population." Only women under 50 who were currently married and living with their husbands were included. The households were restricted to land-based and non-farm families with economically active husbands. There were a total of 4128 families in the sample; in 3768 families the wife had experienced at least 1 birth. A simple 1-period model of household production and fertility demand is outlined. Emphasis was on 2 aspects of the demand for children in households who choose to work in the informal sector: children are more readily employed in a family business; and wife's work in a family business or in a wage employment at home is more compatible with childcare activities. Both effects imply that holding constant other characteristics, a higher desired stock of children will be demanded. As expected, an increase in wife's predicted log earnings in home work had a negative effect on the demand for children. The effect was almost always significant. An increase in wife's productivity in the family business, as proxied by her predicted log earnings in the family business, increased the demand for children significantly. This usually is interpreted to be a result of entering a market activity which is compatible with childcare. Another possible explanation is that the price of children is lowered because if children work in the family business then their productive contributions subsidize their parents' consumption. Yet, without direct measures or proxies for these effects, it is not possible to distinguish between them. An increase in husband's predicted log earnings in wage employment had a significant negative effect on demand for children. This can be interpreted in 2 ways: if an interior solution exists for husband's allocation of time, then a

    The aim of this study is to shed light on the hydrogeochemical characteristics of karst underground waters at shallow depth in Guiyang City, Guizhou Province with an emphasis on the geochemistry of major elements. Guiyang City bears abundant underground waters and it is also an important representative of the karst areas throughout the world. Ca 2+ and Mg 2+ are the dominant cations, accounting for 81%- 99.7% of the total, and HCO -3 and SO 2- 4 are the dominant anions. Weathering of limestones and dolostones is the most important factor controlling the hydrogeochemistry of underground waters, and weathering of sulfate and evaporite rocks is less important. Moreover, the precipitation and human activities also have a definite influence on the hydrogeochemistry of underground waters in the region studied.

    Full Text Available The aggressive extension of the level of underground economy, with a more and more organized developmental character, tends to place the phenomenon as a direct threat to the proper operation of State democratic institutions and, due to the generalized internationalization trend of the phenomenon, quantification and control of underground economy constitutes a problem considered by national governments and international bodies as well. The obvious growth and refinement trends of the methods used by the „practicants” of underground activities impose the need to know and to evaluate this phenomenon, to establish the possibe reaction ways of the public power, according to the cost and consequences forecast on the short term and, especially, on the long term, of the adopted measures. It is therefore necessary to analyze all pertinent factors that influence the level and structure of the underground economy and particularly the fiscal pressure.

    A study of the active population in Verviers during the 1st 1/2 of the 19th century shows that the distribution of immigrants into workers and nonworkers and among the different lines of activity takes place more in line with demographic factors than in line with the real needs of the economy. For instance, the changes in the demographic structure of the working population (younger people and larger numbers of women) removed any rigidity from the employment market. Each element of the production apparatus, including the service industries, was able to count on the human resources necessary for optimum functioning. The available surplus manpower, resulting from immigration, thus made it possible to reach the most profitable production level at the lowest salary costs at the work and technology conditions imposed by the company head.

    Changing the relative price of (in) activity is an important tool for health policies. Nonetheless, to date, analyses of correlates of physical activity (PA) have excluded the notion of price. Using the first nationwide dataset on prices of PA for England, we explore for the first time how money and time prices are associated with PA (in general) and specific activities. A nationally representative telephone follow-up survey to Health Survey for England (HSE) 2008 was undertaken in 2010. The sample covered individuals who reported to have undertaken some PA in the HSE 2008. Questions focussed on: ex-post money and time prices; type and quantity of PA; perceived benefits of PA and socio-economic details. Count regression models (all activities together, and swimming, workout, walking separately) were fitted to investigate the variation in quantity of PA. Of 1683 respondents, 83% participated in PA (one or more activities), and spent an average of £2.40 per occasion of participation in PA and 23 minutes travelling. Participation in PA was negatively associated with money prices per occasion (i.e. family member/child care fees, parking fees, and facility charges) and travel time price. Participation in PA was more sensitive to travel time price than money price. Among the specific activities, the money price effect was highest for swimming with a 10% higher price associated with 29% fewer occasions of swimming; followed by workout (3% fewer occasions) and walking (2% fewer occasions). Only swimming and workout were sensitive to travel time price. People who felt doing PA could help them 'get outdoors', 'have fun', or 'lose weight' were likely to do more PA. Two main policy implications emerge from the findings. First, the results support the notion that positive financial incentives, e.g. subsidising price of participation, could generally lead to an increase in quantity of PA among those already exercising. Second, such policies could lead to desired policy goals if

    Realization of the future Comprehensive Nuclear Test Ban Treaty (CTBT) will require ensuring its compliance, making the CTBT a prime example of forensic seismology. Following indications of a nuclear explosion obtained on the basis of the (IMS) monitoring network further evidence needs to be sought at the location of the suspicious event. For such an On-Site Inspection (OSI) at a possible nuclear test site the treaty lists several techniques that can be carried out by the inspection team, including aftershock monitoring and the conduction of active seismic surveys. While those techniques are already well established, a third group of methods labeled as "resonance seismometry" is less well defined and needs further elaboration. A prime structural target that is expected to be present as a remnant of an underground nuclear explosion is a cavity at the location and depth the bomb was fired. Originally "resonance seismometry" referred to resonant seismic emission of the cavity within the medium that could be stimulated by an incident seismic wave of the right frequency and observed as peaks in the spectrum of seismic stations in the vicinity of the cavity. However, it is not yet clear which are the conditions for which resonant emissions of the cavity could be observed. In order to define distance-, frequency- and amplitude ranges at which resonant emissions could be observed we study the interaction of seismic waves with underground cavities. As a generic model for possible resonances we use a spherical acoustic cavity in an elastic full-space. To solve the forward problem for the full elastic wave field around acoustic spherical inclusions, we implemented an analytical solution (Korneev, 1993). This yields the possibility of generating scattering cross-sections, amplitude spectrums and synthetic seismograms for plane incident waves. Here, we focus on the questions whether or not we can expect resonant responses in the wave field scattered from the cavity. We show

    2003-09-01

    The purpose of the ONKALO Underground Characterisation and Research Programme (UCRP) is to explore Olkiluoto rock conditions and thereby enhance the current geoscientific understanding of the site, to allow the submission of an application for a construction licence for the deep repository. The characterisation programme has the following geoscientific goals: to develop and demonstrate techniques for detailed characterising volumes of rock from the underground, to update the current descriptive model of Olkiluoto bedrock and to increase confidence in this model such that it will serve the needs of construction and the Preliminary Safety Assessment Report (PSAR) in the construction licence application, and to identify volumes of rock that could be suitable for housing parts of the repository. The development of ONKALO will be based on coordinated investigation, design and construction activities. Mapping data from the tunnel front and data obtained from short probe holes will constitute most of the data needed to control the construction of ONKALO. Pilot holes will be drilled along the tunnel profile as the excavation proceeds and investigations will be carried out for geological, rock mechanics, hydrogeological and hydrogeochemical characterisation. Investigations cover more detailed mapping and sampling in parts of the tunnel, mapping and sampling of potential groundwater inflows to the tunnel and investigations from characterisation bore holes drilled from ONKALO. In addition, monitoring is planned in surface-drilled boreholes, in boreholes drilled from ONKALO, and in ONKALO itself. Monitoring will reveal changes in bedrock conditions and thus provide important information for site characterisation. The information collected by characterisation and monitoring will all be assessed in an integrated modelling effort. The aim of this modelling is both to successively enhance the description and understanding of the rock volume around ONKALO and to assess potential

    The 4 m/sup 2/ spark chamber telescope array of the Mt. Cappuccini Laboratory, Torino, At 40 m w.e. underground was operated for about 830 h recording muon showers. The data were analysed with respect to the multiplicity distribution of the shower particles, and to local interactions initiated in the chamber absorbers. Regarding the multiplicity analysis a semi-empirical expression for the likely shower size dependence of a structure function of the analytical form proposed by Vernov et al., was derived and applied with systematically varied parameters. The comparison of the observed rates of multiples with those calculated with a variety of parameters showed that a satisfactory agreement can be attained only if one admits a variation with the shower size of the parameters, and an enhanced muon/electron ratio at the lower primary energies, possibly indicative of an increased abundance of primary heavy nuclei. This would conform with the idea of a two-component primary composition in which a pulsar-produced fraction, enriched in heavy nuclei, dominated only at medium energies. The records on multiplicative interactions, and on large-angle scattering, were analysed by comparing their rates observed for shower particles with those found in single-muon check runs. The results are consistent with the assumption that all shower particle interactions are electromagnetic in nature, and that nonconventional components like mandelas are absent. Only making extreme allowances for statistical fluctuations the data can be made compatible with a mandela flux as large as that suggested by Baruch et al., provided that the mandela attenuation length is less than 1 500g/cm/sup 2/ of rock.

    A central unresolved issue in evolutionary biology is how metabolic innovations emerge. Low-level enzymatic side activities are frequent and can potentially be recruited for new biochemical functions. However, the role of such underground reactions in adaptation toward novel environments has remained largely unknown and out of reach of computational predictions, not least because these issues demand analyses at the level of the entire metabolic network. Here, we provide a comprehensive computational model of the underground metabolism in Escherichia coli. Most underground reactions are not isolated and 45% of them can be fully wired into the existing network and form novel pathways that produce key precursors for cell growth. This observation allowed us to conduct an integrated genome-wide in silico and experimental survey to characterize the evolutionary potential of E. coli to adapt to hundreds of nutrient conditions. We revealed that underground reactions allow growth in new environments when their activity is increased. We estimate that at least ∼20% of the underground reactions that can be connected to the existing network confer a fitness advantage under specific environments. Moreover, our results demonstrate that the genetic basis of evolutionary adaptations via underground metabolism is computationally predictable. The approach used here has potential for various application areas from bioengineering to medical genetics.

    Posiva's repository for geological disposal of the spent fuel from Finnish nuclear reactors will be constructed at Olkiluoto. The selection of Olkiluoto was made based on site selection research programme conducted between 1987-2001. The next step is to carry out complementary investigations of the site and apply for the construction license for the disposal facility. The license application will be submitted in 2012. To collect detailed information of the geological environment at planned disposal depth an underground characterisation and research facility will be built at the site. This facility, named as ONKALO, will comprise a spiral access tunnel and two vertical shafts. The excavation of ONKALO is in progress and planned depth (400 m) will be reached in 2009. During the course of the excavation Posiva will conduct site characterisation activities to assess the structure and other properties of the site geology. The aim is that construction will not compromise the favourable conditions of the planned disposal depth or introduce harmful effects in the surrounding bedrock which could jeopardize the long-term safety of the geological disposal.

    1999-01-01

    The Canadian Institute for Radiation Safety (CAIRS) has developed computer simulation software for modeling radiological parameters in underground uranium mines. The computer program, called 3d RAD, allows radiation protection professionals and mine ventilation engineers to quickly simulate radon and radon progeny activity concentrations and potential alpha energy concentrations in complex mine networks. The simulation component of 3d RAD, called RSOLVER, is an adaptation of an existing modeling program called VENTRAD, originally developed at Queen's University, Ontario. Based on user defined radiation source terms and network physical properties, radiological parameters in the network are calculated iteratively by solving Bateman's Equations in differential form. The 3d RAD user interface was designed in cooperation with the Canada Centre for Mineral and Energy Technology (CANMET) to improve program functionality and to make 3d RAD compatible with the CANMET ventilation simulation program, 3d CANVENT. The 3d RAD program was tested using physical data collected in Canadian uranium mines. 3d RAD predictions were found to agree well with theoretical calculations and simulation results obtained from other modeling programs such as VENTRAD. Agreement with measured radon and radon progeny levels was also observed. However, the level of agreement was found to depend heavily on the precision of source term data, and on the measurement protocol used to collect radon and radon progeny levels for comparison with the simulation results. The design and development of 3d RAD was carried out under contract with the Saskatchewan government

    Full Text Available The aim of this work is to analyze the spatial distribution of potential pollution pathways of water resources given the economic activity in the Mexican border state of Sonora and propose a regional distribution in relation to cancer mortality rates across the state. The methodology is based in an exploratory and inferential data analysis using two sources of primary data: wastewater discharge concessions registered in the Public Registry on Water Rights [Registro Público de Derechos de Agua] (REPDA and the records generated by the National Health Information System [Sistema Nacional de Información en Salud] (SINAIS in the period 1998-2011 based on the International Classification of Disease (ICD-10. The spatial concentration analysis allows for the identification of specific cancer mortality causes at the regional level. Results indicate that the projected adjustments to the regulation NOM-250-SSA1-2014, which controls a subset of pollutants common in mining activity surroundings, is a matter of regional concern.

    AECL Research has constructed an underground laboratory for the research and development required for the Canadian Nuclear Fuel Waste Management Program. The experimental program in the laboratory will contribute to the assessment of the feasibility and safety of nuclear fuel waste disposal deep in stable plutonic rock. In 1988, AECL extended the shaft of the Underground Research Laboratory (URL) from the existing 255 m depth to a depth of 443 m in cooperation with the United States Department of Energy. The project, which involved carrying out research activities while excavation and construction work was in progress, required careful planning. To accommodate the research programs, full-face blasting with a burn cut was used to advance the shaft. Existing facilities at the URL had to be modified to accommodate an expanded underground facility at a new depth. This paper discusses the design criteria, shaft-sinking methods and approaches used to accommodate the research work during this shaft extension project. (11 refs., 11 figs.)

    The feasibility of underground coal gasification is evaluated on the basis of a case study for India. India has immense coal reserves at relatively shallow depths compared to Europe, has low wages, an urgent need to expand its power capacity, a strongly rising energy demand and has shown interest in underground coal gasification. Three scenarios including the cases of continued, declining and a strong economic growth were considered. Model calculations allow to compare the cost of the electric power generated by the combustion of the gas produced by underground coal gasification with the cost of the power produced by classic thermal power plants in India for -the reference year 2000.

    Favored by the low background in underground laboratories, low-background accelerator-based experiments are an important tool to study nuclear reactions involving stable charged particles. This technique has been used for many years with great success at the 0.4 MV LUNA accelerator in the Gran Sasso laboratory in Italy, proteced from cosmic rays by 1400 m of rock. However, the nuclear reactions of helium and carbon burning and the neutron source reactions for the astrophysical s-process require higher beam energies than those available at LUNA. Also the study of solar fusion reactions necessitates new data at higher energies. As a result, in the present NuPECC long range plan for nuclear physics in Europe, the installation of one or more higher-energy underground accelerators is strongly recommended. An intercomparison exercise has been carried out using the same HPGe detector in a typical nuclear astrophysics setup at several sites, including the Dresden Felsenkeller underground laboratory. It was found that its rock overburden of 45m rock, together with an active veto against the remaining muon flux, reduces the background to a level that is similar to the deep underground scenario. Based on this finding, a used 5 MV pelletron tandem with 250 μA upcharge current and external sputter ion source has been obtained and transported to Dresden. Work on an additional radio-frequency ion source on the high voltage terminal is underway. The project is now fully funded. The installation of the accelerator in the Felsenkeller is expected for the near future. The status of the project and the planned access possibilities for external users will be reported.

    Full Text Available Within any branch of material production, the supervision of the economic effects caused by the applied technologies is an essential requirement. Not only related to the productive activity, but also related to scientific research, designing and other fields of activity, the final goal is represented by the achievement of immediate or far off economic effects. The introduction and generalization into production of the newest technologies of forage production must rely upon calculations of economic efficiency, too. The objective of these calculations is to offer to any producer the possibility to choose among the optimal technologic variants, with great productions per surface unit, of high quality and low costs. The calculations of economic efficiency were carried out during the three years of experimentation. The economic efficiency obtained after the application of biostimulants in smooth brome during the first year of production is expressed through the achievement of a profit per surface unit of 75.85 – 127.00 €/ha. Successive to the calculations of economic efficiency, during the second year of production, the profit per surface unit recorded values between 79.10 – 153.10 €/ha depending upon the applied biostimulant, and during the third year of production the profit obtained per surface unit was 211.05 – 270.70 €/ha.

    This chapter gives the reader an introduction into the microbiology of deep geological systems with a special focus on potential geobiotechnological applications and respective risk assessments. It has been known for decades that microbial activity is responsible for the degradation or conversion of hydrocarbons in oil, gas, and coal reservoirs. These processes occur in the absence of oxygen, a typical characteristic of such deep ecosystems. The understanding of the responsible microbial processes and their environmental regulation is not only of great scientific interest. It also has substantial economic and social relevance, inasmuch as these processes directly or indirectly affect the quantity and quality of the stored oil or gas. As outlined in the following chapter, in addition to the conventional hydrocarbons, new interest in such deep subsurface systems is rising for different technological developments. These are introduced together with related geomicrobiological topics. The capture and long-termed storage of large amounts of carbon dioxide, carbon capture and storage (CCS), for example, in depleted oil and gas reservoirs, is considered to be an important options to mitigate greenhouse gas emissions and global warming. On the other hand, the increasing contribution of energy from natural and renewable sources, such as wind, solar, geothermal energy, or biogas production leads to an increasing interest in underground storage of renewable energies. Energy carriers, that is, biogas, methane, or hydrogen, are often produced in a nonconstant manner and renewable energy may be produced at some distance from the place where it is needed. Therefore, storing the energy after its conversion to methane or hydrogen in porous reservoirs or salt caverns is extensively discussed. All these developments create new research fields and challenges for microbiologists and geobiotechnologists. As a basis for respective future work, we introduce the three major topics, that is

    A sampling expedition into the East Coast Peninsula Malaysia Exclusive Economic Zone (EEZ) was carried in June 2008. Marine surface sediment samples were taken and the activity concentrations of 210 Pb have been determined. Its distribution was plotted and the findings show that the activity concentrations decline from north to south. On the other hand, the activity concentrations are increasing from west to east right to the edge of the EEZ. The highest activity concentrations were found to be near offshore oil platforms. The 210 Pb activity concentrations were found to be in the range of 18.3 - 123.1 Bq/ kg. (author)

    A key requirement for underground nuclear astrophysics experiments is the very low background level in germanium detectors underground. The reference for these purposes is the world's so far only underground accelerator laboratory for nuclear astrophysics, LUNA. LUNA is located deep underground in the Gran Sasso laboratory in Italy, shielded from cosmic rays by 1400 m of rock. The background at LUNA was studied in detail using an escape-suppressed Clover-type HPGe detector. Exactly the same detector was subsequently transported to the Felsenkeller underground laboratory in Dresden, shielded by 45 m of rock, and the background was shown to be only a factor of three higher than at LUNA when comparing the escape-suppressed spectra, with interesting consequences for underground nuclear astrophysics. As the next step of a systematic study of the effects of a combination of active and passive shielding on the cosmic ray induced background, this detector is now being brought to the ''Reiche Zeche'' mine in Freiberg/Sachsen, shielded by 150 m of rock. The data from the Freiberg measurement are shown and discussed.

    Full Text Available This paper deals with finding solutions for improving the economic activities in Romania’s undeveloped areas, which still represent a major problem for this country’s economy. During 1999 and 2009, these areas were considered tax havens, due to some facilities accorded by the Government and the EU (headage compensatory allowances*, tax deductions, non-refundable funds. Many had the opportunity to invest in those regions, but no positive effect was to be seen. Tulcea County (Danube Delta area, coal mine regions, rural areas and the North-East area (Suceava and Botosani county are considered to be Romania’s less favoured areas. * The objective of these schemes is to provide a reasonable level of income for farmers where natural production conditions are least favourable so as to conserve the countryside by the prevention of further depopulation of rural areas. Compensatory allowances are payable to farmers for the keeping of cattle, sheep and goats. (www.europa.eu

    Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7-9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.

    The aim of the present study was to develop (phase 1) and validate (phase 2) a screening questionnaire to assess the adequacy of micronutrient intake of economically active South African adults. For identification of indicator foods to be included in the screening questionnaire (phase 1), a comprehensive, eighty-six-item, quantified FFQ that reflected the food sources of thirteen selected micronutrients associated with the nutrition-related health status of South Africans was developed and completed by 554 adults of all four major ethnic groups. Resulting dietary data were subjected to stepwise regression analyses to identify indicator foods to be included in the final screening questionnaire. For validation of frequency of intake reporting of specific food items included in the screening questionnaire (phase 2), a sample of sixty-six African and eighty-four white adult volunteers of both genders completed a 7 d record as well as the screening questionnaire. The frequency of intake of specific food items derived from the two methods was then compared using Spearman correlation coefficients. Phase 1 identified thirty indicator foods that formed the basis of the screening questionnaire. In phase 2, significant correlations were found for the total group for twenty-two out of the thirty items in the questionnaire, with correlations being the best for white females and the poorest for African males and females. A screening questionnaire (thirty-item FFQ) that can be used by researchers and health professionals to assess an individual's risk of inadequate micronutrient intake was developed and validated.

    Full Text Available This article offers some recommendations to improve the efficiency of the cooperatives pointing out the deficiencies and irregularities in the management and administration as well as in the effective control of the supporting personal to the assigned tasks. It treats about the hidden arty-crafty and tricks which wait for us when we control or do not control, when we delegate or have been delegated, as well as team work. We point out how to analyze the pros and contras of these situations and how to proceed in each case. We also tell, as an effective procedure to improve the efficiency or the cooperatives, the control of the production and the material and human resources, due to the fact that the working climax is in danger in not few organizations. Accountability is one of the most vulnerable branches. In this activity there are inadequate primary data that make possible the manipulation of counts as to hide illegal events. Amen of the money in safe and the goods of value to which sudden archly are not made, these are some of the fissures that incite wrongdoing. To resolve such challenges are some of the premises in the bring up to date of the Cuban Economic Model.

  18. Economic and occupational implications of upstream activity. The Eni-Agip case

    This report evaluates the national and regional economic implications, for Italy, of the exploration and development activity in the petroleum sector (at the domestic and international level), with reference being made to the specific case of Eni's Agip Division. The business considered here is basically of an investment nature; as a result, the supply of goods and services Agip Division requires of the Italian production sectors represents an autonomous component of the domestic demand, to which induced effects are attributable. The study has revealed that Eni-Agip's demand plays a central role in promoting domestic production and in the extent of the induced effects in terms of creation of added value and employment. From this point of view, the specific nature of its demand places Eni-Agip at the top of the system of the large domestic enterprises, whose role as the dynamo of the national economy has gradually decreased. Viceversa, Eni-Agip's ability to promote domestic production and employment proves to be lower than that of the sectors where the presence of medium- and small- sized firms is prevalent, a fact that confirms their increasing role in the Italian economy. As far the territorial aspect is concerned, the promotion of production and jobs brought about by Eni-Agip's demand obviously affects the country's most productive regions, especially where industrial supplies are involved, but its specific regional distribution entails also a significant local interest in different central-southern regions of the country [it

    Inoue, Y.; Morisawa, S.

    Experimental studies were made of the variations of the distribution coefficient of 65 Zn, 60 Co, and /sup 110 m/Ag with Ca ion contents in sand--water and resin--water systems. It is concluded that: (1) The distribution coefficient of a radionuclide is not constant but varies greatly especially with calcium ion concentration in underground water. (2) The Saturation Index I=pH-pHs can be used as a parameter to indicate such variations. (3) Some radionuclides, existing as radiocolloids like (sup 110m/Ag and 59 Fe, are inactive toward ion exchange reactions as with hydroxide. In such cases, the nuclides migrate underground as fast as underground water
