  3. Geotechnical Field Data and Analysis Report, July 1989--June 1990

    International Nuclear Information System (INIS)

    1991-03-01

    The Geotechnical Field Data and Analysis Report documents the data obtained from geomechanical instruments in the underground at the Waste Isolation Pilot Plant (WIPP). The data are obtained as part of a routine monitoring program and do not include data from tests performed to support performance assessment studies by Sandia National Laboratories, the Scientific Advisor to the project. The purpose for obtaining the geomechanical data is to understand and predict performance of the repository during operations. During the Site and Preliminary Design Validation (SPDV) Program, the Architect/Engineer, for the project, produced quarterly reports to document the geomechanical performance of construction. Since 1987, after the completion of construction, the reports have been prepared annually by the Managing and Operating Contractor for the facility. This report includes data collected up to June 30, 1990, and describes the performance and conditions of selected areas from July 1, 1989, to June 30, 1990. 11 refs., 49 figs., 8 tabs

    The Geotechnical Field Data and Analysis Report presents the data for the assessment of the geotechnical status of the Waste Isolation Pilot Plant (WIPP). During the period of shaft sinking and construction of the principal underground access and experimental areas, reporting was on a quarterly basis. Since 1987, reporting has been carried out annually because excavation of the waste storage panels will take place more slowly and over an extended period. This report presents the data collected up to June 30, 1990. The report focuses on the presentation of geotechnical data from the various underground facilities including the shafts, shaft stations, access drifts, test rooms, and waste storage areas. It also describes the techniques used to acquire the data and the performance history of the instruments. 371 figs., 9 tabs

    The present report deals with the neonatal mortality in Bavaria during 1972 to 1990, the last period of which coincided with the reactor accident of Chernobyl. The question arose whether there was an increase in neonatal mortality in the more heavily exposed regions of Bavaria as an aftermath to this accident. The results of the study may be summarized as follows: During the period of interest there was a decrease in neonatal mortality in the Federal Republic of Germany (former Federal Lands) and in Bavaria from 22 permille (1972) to less than one third of this value. With a mortality rate of 6.2 permille . Bavaria was below the Federal average of 7.1 permille . in 1990. This decrease is mainly due to a decline in early mortality. Mortality during the first year of life was higher in male than in female infants. 57% of the deceased infants were male, 43% female. The spatial distribution of neonatal mortality in Bavaria showed large regional differences. Following standardisation of the raw data the lowest value of a rural district averaged over the 19 years covered was 7.1 permille , the highest being 21 permille . When the infant mortality rates of regions in Southern Bavaria which were defined as being more heavily exposed to radiation after the Chernobyl accident (> 30 kBq/m 2 Cs- 137), no statistically significant difference was detected for any of the year between 1980 to 1990. Similarly, no statistical correlation could be found between neonatal mortality and proximity of the residence to one of the five sites of nuclear reactors in Bavaria. Out of the further environmental variables included in the study the factors 'urbanity' and 'unemployment' showed a statistical correlation with the infant mortality rate. Over the entire study period (1972 to 1990) the infant mortality rate was found to be significantly increased in towns (constituting administrative districts of their own) compared to rural districts.

  6. Geotechnical field data and analysis report, July 1990--June 1991

    International Nuclear Information System (INIS)

    1992-03-01

    The Geotechnical Field Data and Analysis Report documents the geotechnical data from the underground excavations at the Waste Isolation Pilot Plant (WIPP) located near Carlsbad, New Mexico. The data are used to characterize conditions, confirm design assumption, and understand and predict the performance of the underground excavations during operations. During the construction of the principal underground access and experimental areas, reporting was on a quarterly basis. Since 1987, reporting has been carried out annually because additional excavations such as the waste storage panels, will take place gradually over an extended period. This report presents and analyzes data collected up to June 30, 1991. The two-volume format of the Geotechnical Field Data and Analysis Report was selected to meet the needs of several audiences. Volume I focuses on the geotechnical performance of the various underground facilities including the shafts, shaft stations, access drifts, test rooms, and waste storage areas. The results of excavation effects investigations, stratigraphic mapping, and the occurrence of brine are also documented. It provides an evaluation of the geotechnical aspects of performance in the context of the relevant design criteria. The depth and breadth of the evaluation for the different underground facilities varies according to the types and quantities of data that are available, and the complexity of the recorded geotechnical responses

    This chapter summarizes the results of geotechnical measurements made on cores taken at the three deep ocean sites that have been studied in detail as part of the international programme assessing the feasibility of deep ocean disposal of heat-generating radioactive waste. The capabilities of existing sampling methods and the adequacy of the available data for providing the geotechnical parameters needed to evaluate the technical feasibility of deep ocean disposal are discussed. It is concluded that, while it has not been possible to obtain core samples of sufficient quality and depth to provide all the parameters needed for the assessment, no fundamental differences between the sediments at the study areas and those found on land or in shallow water have been identified.

    Between January 1972 and December 1990, bulk-tank (n = 721) and cow (n = 9,163) milk samples from dairy herds in New York State were examined by bacteriologic procedures for Mycoplasma. The organism was found in 165 herds in 42 counties, and in 2.3 and 11.7% of the tank and cow samples, respectively. Mycoplasma bovis was isolated in 164 herds, M. californicum was isolated in 1. Highest incidence of mycoplasmal clinical mastitis occurred during the winter. The disease resulted in culling of 30-70% of the cows in several herds. Eighty-six of the positive herds were located in the western part of the state. This area had more large herds (greater than 200 cows) compared to the rest of the state; however, herd size was not a risk factor. Purchased animals added to herds without quarantine, poor hygiene during mastitis treatment, and personnel in contact with mastitic cows or infected milk were involved in outbreaks and disease transmission.

    This report presents physical property logs of core samples from an offshore area near Eureka, CA. The cores were obtained as part of the STRATAFORM Program (Nittrouer and Kravitz, 1995, 1996), a study investigating how present sedimentation and sediment transport processes influence long-term stratigraphic sequences preserved in the geologic record. The core samples were collected during four separate research cruises to the northern California study area, and data shown in the logs of the cores were collected using a multi-sensor whole core logger. The physical properties collected are useful in identifying stratigraphic units, ground-truthing acoustic imagery and sub-bottom profiles, and in understanding mass movement processes. STRATA FORmation on Margins was initiated in 1994 by the Office of Naval Research, Marine Geology and Geophysics Department as a coordinated multi-investigator study of continental-margin sediment transport processes and stratigraphy (Nittrouer and Kravitz, 1996). The program is investigating the stratigraphic signature of the shelf and slope parts of the continental margins, and is designed to provide a better understanding of the sedimentary record and a better prediction of strata. Specifically, the goals of the STRATAFORM Program are to (Nittrouer and Kravitz, 1995): - determine the geological relevance of short-term physical processes that erode, transport, and deposit particles and those processes that subsequently rework the seabed over time scales - improve capabilities for identifying the processes that form the strata observed within the upper ~100 m of the seabed commonly representing 104-106 years of sedimentation. - synthesize this knowledge and bridge the gap between time scales of sedimentary processes and those of sequence stratigraphy. The STRATAFORM Program is divided into studies of the continental shelf and the continental slope; the geotechnical group within the U.S. Geological Survey provides support to both parts

    2014-05-01

    The purpose of this paper is to carry out a geotechnical evaluation of the underground within an urban setting in relation to types of foundations, and particularly at expansion zones. The ultimate aim is to produce a foundation zonation map at the scale 1:10,000. Furthermore, a general methodology that way be extrapolated to other cities is proposed. This work focused on the city of Aviles like a case study; a medium-sized city which has significant industrial and port areas and singular equipment in its surroundings. This city is located in the Spanish north coast and spread out on both flanks of the Avilés stuary. This means that there are an important development of recent deposits that implies different geotechnical units with a highly variable behavior, generally poor. In contrast, the bedrock is more homogenous, formed by Permo-Triassic red clay and marl. Locally there are also outcrops of carbonates and conglomeratic Jurassic levels. Also, on the whole area is important to note the presence of heterogeneous anthropic deposits along the whole area as a consequence, mainly, of an intense industrial activity. Permo-Triassic clayey and marly materials imply special engineering issues in foundations as a consequence of their composition (likely weathering, presence of gypsum, low bearing capacity). Moreover, recent deposits (marine and alluvial origin) show different geotechnical behaviors depending on their geometry and grain size. Hence, many areas of the city are especially problematic when designing and implementing foundations. The methodology followed in this study consisted in elaborating a geological-geotechnical exhaustive survey of the urban underground on a scale of 1/10.000. Based on this, a multi criteria analysis of the identified geotechnical units was carried out taking into consideration all the lithological, geomorphological, hidrogeological and geotechnical aspects. Taken into account all of these criteria, a number of areas are defined based

    Full Text Available ABSTRACT: While more than half the land surface of Iraq consists of deserts covered mainly with sand dunes, little research has taken place to study the characteristics and the behavior of dune soils. This paper directed toward studying the geotechnical properties of dune sands taken from Baiji city (northwest of Iraq. A vast laboratory testing program was carried out to achieve the purpose of this paper. The physical tests, chemical tests, X-ray diffraction analysis, permeability test, compaction characteristics, compressibility and collapsibility tests; and shear strength tests were included in this program. The results indicate that soil of Baiji sand dune exhibits prefer engineering properties according to their state. As such, this soil is considered suitable for use in geotechnical constructions. ABSTRAK: Walaupun lebih separuh daripada bumi Iraq terdiri daripada gurun yang dipenuhi dengan bukit-bukit pasir, tidak banyak penyelidikan dijalankan untuk mengkaji sifat-sifat dan ciri-ciri tanah pasir  tersebut.

    In this paper a specific example of the synergistic use of geotechnical survey, remote sensing data and GIS for rockfall risk evaluation is presented. The study area is located in Western Greece. Extensive rockfalls have been recorded along Patras - Ioannina highway just after the cable-stayed bridge of Rio-Antirrio, at Klokova site. The rockfalls include medium- sized limestone boulders with volume up to 1.5m3. A detailed engineering geological survey was conducted including rockmass characterization, laboratory testing and geological - geotechnical mapping. Many Rockfall trajectory simulations were done. Rockfall risk along the road was estimated using spatial analysis in a GIS environment.

    RFS or Regles Fondamentales de Surete (Basic Safety Rules) applicable to certain types of nuclear facilities lay down requirements with which compliance, for the type of facilities and within the scope of application covered by the RFS, is considered to be equivalent to compliance with technical French regulatory practice. The object of the RFS is to take advantage of standardization in the field of safety, while allowing for technical progress in that field. They are designed to enable the operating utility and contractors to know the rules pertaining to various subjects which are considered to be acceptable by the Service Central de Surete des Installations Nucleaires, or the SCSIN (Central Department for the Safety of Nuclear Facilities). These RFS should make safety analysis easier and lead to better understanding between experts and individuals concerned with the problems of nuclear safety. The SCSIN reserves the right to modify, when considered necessary, any RFS and specify, if need be, the terms under which a modification is deemed retroactive. The purpose of this RFS is to specify the soil characteristics to be determined and the soil response studies to be performed as part of site geological and geotechnical studies

    The safety assessment of disposal of spent nuclear fuel will include an estimate on the behavior of nuclear waste nuclides in the biosphere. As a part of this estimate also the transfer of nuclear waste nuclides in the soil and sediments is to be considered. In this study soil samples were collected from three excavator pits in Olkiluoto and the geotechnical and chemical characteristics of the samples were determined. In later stage these results will be used in sorption tests. Aim of these tests is to determine the Kd-values for Cs, Tc and I and later for Mo, Nb and Cl. Results of these sorption tests will be reported later. The geotechnical characteristics studied included dry weight and organic matter content as well as grain size distribution and mineralogy analyses. Selective extractions were carried out to study the sorption of cations into different mineral types. The extractions included five steps in which the cations bound to exchangeable, carbonate, oxides of Fe and Mn, organic matter and residual fractions were determined. For all fractions ICPMS analyses were carried out. In these analyses Li, Na, Mg, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Cs and Pb were determined. In addition six profiles were taken from the surroundings of two excavator pits for the 137 Cs determination. Besides the samples taken for the characterization of soil, supplement samples were taken from the same layers for the separation of soil water. From the soil water pH, DOC, anions (F, Cl, NO 3 , SO 4 ) and cations (Na, Mg, K, Ca, Al, Cr, Mn, Fe, Ni, Cu, Zn, As, S, Cd, Cs, Pb, U) were determined. (orig.)

    The Eye-Dashwa Lakes pluton near Atikokan Ontario has been used as a study area for the Canadian nuclear fuel waste management research program. The pluton consists predominately of granite. Fractures formed during cooling of the pluton were filled with a succession of different materials at different times. Measurements of a series of geophysical and geotechnical properties of rock samples are published here in this report, including especially microcrack and pore structures. An indication has been found that a larger proportion of the porosity of Whiteshell and Atikokan samples is contained in connecting pores, compared to other rocks. This may seem surprising in view of the finding that approximately 70% of the effective porosity of Atikokan samples is contained in pockets

    During the period from 1.1.90 until 31.12.90, 86 injuries associated with paragliding were analyzed in a prospective study in 12 different Swiss hospitals with reference to causes, patterns, and frequencies. The injuries showed a mean score of over 2 and were classified as severe. Most frequent spine injuries (36%) and lesions of the lower extremity (35%) with a high risk of the ankles were diagnosed. One accident was fatal. 60% of the accidents happened during landing, 26% during launching and 14% during flight. Half of the pilots were affected during their primary training course. Most accidents were caused by inflight error of judgement--especially incorrect estimation of wind conditions--and further the choice of unfavourable landing sites. In contrast to previous injury-reports, only one equipment failure could be noted, but often the equipment was not corresponding with the experience and the weight of the pilot. To reduce the frequency of paragliding-injuries an accurate choice of equipment and an increased attention to environmental factors is mandatory. Furthermore an education-program regarding the attitude and intelligence of the pilot should be included in training courses.

    1992-12-01

    The objectives of this report are three-fold: (1) assess physical, chemical, and biological conditions in the major embayments of Chickamauga Reservoir; (2) compare water quality and biological conditions of embayments with main river locations; and (3) identify any water quality concerns in the study embayments that may warrant further investigation and/or management actions. Embayments are important areas of reservoirs to be considered when assessments are made to support water quality management plans. In general, embayments, because of their smaller size (water surface areas usually less than 1000 acres), shallower morphometry (average depth usually less than 10 feet), and longer detention times (frequently a month or more), exhibit more extreme responses to pollutant loadings and changes in land use than the main river region of the reservoir. Consequently, embayments are often at greater risk of water quality impairments (e.g. nutrient enrichment, filling and siltation, excessive growths of aquatic plants, algal blooms, low dissolved oxygen concentrations, bacteriological contamination, etc.). Much of the secondary beneficial use of reservoirs occurs in embayments (viz. marinas, recreation areas, parks and beaches, residential development, etc.). Typically embayments comprise less than 20 percent of the surface area of a reservoir, but they often receive 50 percent or more of the water-oriented recreational use of the reservoir. This intensive recreational use creates a potential for adverse use impacts if poor water quality and aquatic conditions exist in an embayment.

    International Nuclear Information System (INIS)

    1988-01-01

    This multidisciplinary project was initiated in fiscal year 1986. It comprises 11 reports in two major interrelated tasks: The technical assistance part of the project includes reviewing the progress of the major projects in the DOE Office of Civilian Radioactive waste Management (OCRWM) Program and advising the Engineering and Geotechnology Division on significant technical issues facing each project; analyzing geotechnical data, reports, tests, surveys and plans for the different projects; reviewing and commenting on major technical reports and other program documents such as Site Characterization Plans (SCP) and Study Plans; and providing scientific and technical input at technical meetings. The topical studies activity comprises studies on scientific and technical ions and issues of significance to in-situ testing, test analysis methods, and site characterization of nuclear waste geologic repositories. The subjects of study were selected based on discussions with DOE staff. One minor topic is a preliminary consideration and planning exercise for postclosure monitoring studies. The major task, with subtasks involving various geoscience disciplines, is a study of the mechanical, hydraulic, geophysical and geochemical properties of fractures in geologic rock masses

    The determination of parameters comprising exact depth to bedrock and its lithological type, lateral changes in lithology, and detection of fractures, cracks, or faults are essential to designing formidable foundations and assessing the integrity of civil engineering structures. In this study, soil and site characterization in a typical hard rock geologic terrain in southwestern Nigeria were carried out employing integrated geophysical and geotechnical techniques to address tragedies in civil engineering infrastructural development. The deployed geophysical measurements involved running both very low frequency electromagnetic (VLF-EM) and electrical resistivity methods (dipole-dipole imaging and vertical electrical sounding (VES) techniques) along the established traverses, while the latter technique entailed conducting geological laboratory sieve analysis and Atterberg limit-index tests upon the collected soil samples in the area. The results of the geophysical measurement, based on the interpreted VLF-EM and dipole-dipole data, revealed conductive zones and linear features interpreted as fractures/faults which endanger the foundations of public infrastructures. The delineation of four distinct geoelectric layers in the area—comprised of topsoil, lateritic/clayey substratum, weathered layer, and bedrock—were based on the VES results. Strong evidence, including high degree of decomposition and fracturing of underlying bedrock revealed by the VES results, confirmed the VLF-EM and dipole-dipole results. Furthermore, values in the range of 74.2%-77.8%, 55%-62.5%, 23.4%-24.5%, 7.7%-8.2%, 19.5%-22.4%, and 31.65%-38.25% were obtained for these geotechnical parameters viz soil percentage passing 0.075 mm sieve size, liquid limit, plasticity index, linear shrinkage, natural moisture content, and plastic limit, respectively, resulting from the geotechnical analysis of the soil samples. The comparatively analyzed geophysical and geotechnical results revealed a high

    Geotechnical characterization of the Main Drift of the Exploratory Studies Facility was based on borehole data collected in site characterization drilling and on scanline rock mass quality data collected during the excavation of the North Ramp. The Main Drift is the planned 3,131-m near-horizontal tunnel to be excavated at the potential repository horizon for the Yucca Mountain Site Characterization Project. Main Drift borehole data consisted of three holes--USW SD-7, SD-9, and SD-12--drilled along the tunnel alignment. In addition, boreholes USW UZ-14, NRG-6, and NRG-7/7A were used to supplement the database on subsurface rock conditions. Specific data summarized and presented included lithologic and rock structure core logs, rock mechanics laboratory testing, and rock mass quality indices. Cross sections with stratigraphic and thermal-mechanical units were also presented. Topics discussed in the report include geologic setting, geologic features of engineering and construction significance, anticipated ground conditions, and the range of required ground support. Rock structural and rock mass quality data have been developed for each 3-m interval of core in the middle nonlithophysal stratigraphic zone of the Topopah Spring Tuff Formation. The distribution of the rock mass quality data in all boreholes used to characterize the Main Drift was assumed to be representative of the variability of the rock mass conditions to be encountered in the Main Drift. Observations in the North Ramp tunnel have been used to project conditions in the lower lithophysal zone and in fault zones

    The study location was at Bukit Kukus, Kuala Ketil, Kedah, Malaysia where the geological outcrop of this Semanggol Formation comprises of chert, mudstone, and volcanic tuff. The study was conducted using two geophysical methods, which are 2-D Resistivity and Ground Penetrating Radar (GPR). The objectives of the study are to correlate both of the geophysical methods through the value of conductivity and to identify the physical properties of rocks through the value of porosity and permeability. The data acquisition for both methods was conducted on the same line. For 2-D Resistivity method, the length of the line is 60 m with 1.5 m electrode spacing and the array used was Wenner-Schlumberger. For GPR method, the survey line was on top of the resistivity line, and the frequency of the antenna used is 250 MHz. A good correlation exists between both of the GPR signature and contour maps for resistivity from the surfer 10 software with the outcrop feature. Conductivity value from both GPR and Resistivity method was compared and the range value of conductivity obtained from GPR method almost equivalent with Resistivity method based on derivation and calculation for the sedimentary rocks, which are 0.037 to 0.574 miliSiemens per metre (mS/m) for chert and 0.186 to 10.142 miliSiemens per metre (mS/m) for mudstone. Two types of rock samples were taken, and several geotechnical tests were conducted, but only the value of permeability, K and porosity, ɸ of chert can be calculated, which are 1.95E-22 m2 (original condition) and 2.27E-22 m2 (dry condition) and 3 percent respectively as the sample of mudstone was damaged. The parameter of the 2-D resistivity method derived from Archie’s law was used to calculate the porosity, ɸf value using the Formation Factor equation. The range values of porosity, ɸf for chert mostly in the range of 5 to 25 percent, which is 6.26 to 13.36 percent but slightly out of range for mudstone, which is 14.12 to 36.02 percent.

    For several decades, geophysical prospecting method coupled with geotechnical analysis has become increasingly useful in evaluating the subsurface for both pre and post engineering investigations. Shallow geophysical tool is often used alongside geotechnical method to evaluate subsurface soil for engineering study to obtain information which may include the subsurface lithology and their thicknesses, competence of the bedrock and depths to its upper interface, and competence of the material that make up the overburden, especially the shallow section which serves as host for foundations of engineering structures (Aina et al., 1996; Adewumi and Olorunfemi, 2005; and Idornigie et al., 2006). This information helps the engineers to correctly locate and design the foundation of engineering structures. The information also serves as guide to the choice of design and suitable materials needed for road construction (Akinlabi and Adeyemi, 2014). Lack of knowledge of the properties of subsurface may leads to the failure of most engineering structures. Therefore, it is of great importance to carry out a pre-construction investigation of a proposed site in order to ascertain the fitness of the host earth material.

    Makassar city have relatively lower earthquake vulnerability compared to other regions in Indonesia, however detailed mapping related to seismic wave amplification needs to be done in the interest of geotechnical, regional planning and disaster mitigation. It is generally known that the magnitude of the damage during the occurrence of earthquakes or tremor occur periodically is influenced by the dynamic characteristics of the building as a function of seismic wave amplification. The degree of seismic wave amplification depends on several factors, including the thickness of the sediment layer, the level of compaction and the geological age factor. The purpose of this research is to investigate seismic vulnerability in Makassar by using spectral comparison through microtremor measurement. There are several of the approaches that can be done and microtremor is the easiest and cheapest method to understand these dynamic characteristics without causing damage effects. Spectra comparison technique used was popular by Nakamura, which is comparison technique of horizontal component noise spectra and the vertical component in sediment areas (H/V spectra). Results from seismic vulnerability index (SVI) distribution maps show values ranging from 0, 14 - 158, 31. In general, the eastern part of the city of Makassar near from coastal areas is more vulnerable to damage especially earthquakes or periodic earth tremor with certain dominant frequency compared with the western part of Makassar City.

  18. Seismic behaviour of geotechnical structures

    F. Vinale

    2002-06-01

    Full Text Available This paper deals with some fundamental considerations regarding the behaviour of geotechnical structures under seismic loading. First a complete definition of the earthquake disaster risk is provided, followed by the importance of performing site-specific hazard analysis. Then some suggestions are provided in regard to adequate assessment of soil parameters, a crucial point to properly analyze the seismic behaviour of geotechnical structures. The core of the paper is centered on a critical review of the analysis methods available for studying geotechnical structures under seismic loadings. All of the available methods can be classified into three main classes, including the pseudo-static, pseudo-dynamic and dynamic approaches, each of which is reviewed for applicability. A more advanced analysis procedure, suitable for a so-called performance-based design approach, is also described in the paper. Finally, the seismic behaviour of the El Infiernillo Dam was investigated. It was shown that coupled elastoplastic dynamic analyses disclose some of the important features of dam behaviour under seismic loading, confirmed by comparing analytical computation and experimental measurements on the dam body during and after a past earthquake.

    1991-01-01

    In recent years, a few geotechnical studies have been conducted by the Central Mining Research Station, Dhanbad, at Jaduguda mine to improve ground control system and to optimise stopping parameters in the wide orebody zone at deeper levels and thus to add to productivity and recovery of these mines ensuring adequate safety. The replacement of mechanical point-anchored rock-bolts by full column cement grouted bolts, installed as per the designed pattern, has improved the ground condition, decreased the consumption of timber supports by around 70%, curtailed the support installation time and reduced the support cost to a remarkable extent even at the most problematic sites of Jaduguda mine. The analysis of stress development observations in the slope pillars of this mine reveals that the size of the slope pillars may be reduced by 20% in width which means an extra recovery of about 75 to 100 tonnes of ore per pillar per slice. In this paper, the authors have presented a brief account of their studies at this mine in the last four years. (author). 10 refs., 10 tabs., 9 figs

    The Department of Energy and the Department of Defense are actively pursuing a program of nuclear weapons testing by underground explosions at the Nevada Test Site (NTS). Over the past 11 years, scores of tests have been conducted and the safety record is very good. In the short run, emphasis is put on preventing the release of radioactive materials into the atmosphere. In the long run, the subsidence and collapse of the ground above the nuclear cavities also are matters of interest. Currently, estimation of containment is based mostly on empiricism derived from extensive experience and on a combination of physical/mechanical testing and numerical modeling. When measured directly, the mechanical material properties are obtained from short-term laboratory tests on small, conventional samples. This practice does not determine the large effects of scale and time on measured stiffnesses and strengths of geological materials. Because of the limited data base of properties and in situ conditions, the input to otherwise fairly sophisticated computer programs is subject to several simplifying assumptions; some of them can have a nonconservative impact on the calculated results. As for the long-term, subsidence and collapse phenomena simply have not been studied to any significant degree. This report examines the geomechanical aspects of procedures currently used to estimate containment of undergroung explosions at NTS. Based on this examination, it is concluded that state-of-the-art geological engineering practice in the areas of field testing, large scale laboratory measurements, and numerical modeling can be drawn upon to complement the current approach.

    The article provides an experimental material showing an investigation of soil under the foundations base of a dangerous block of the building. The investigation was carried out by applying load from a stamp on the soil with a jack supporting the foundation base of the deformed building. There were originally offered two options to strengthen the foundation - a broader base and improvement of the soil with the plate. However, quite a different option was accepted due to the full scale tests. The effective way to strengthen the foundation is measures undertaken without strengthening the soil and without increasing the width of the base, using the actual soil with deformations stabilized for years of operation. The strengthening of the bearing brick walls was made by tightening the main face laying with steel channel profiles to make a firm contact with the foundations. The conducted investigation is an example of geotechnical consulting and improvement of the geotechnical maintenance of dangerous structures at the stages of investigation, design and reconstruction.

    In the Oslo cardiovascular study of 1972-3 a 5-year randomized trial in mild to moderate hypertension was performed. Several changes in treatment practices have been recommended since that time. We followed the mortality patterns up to 40 years. Invited to the Oslo study screening were 25,915 middle-aged men and 16,203 (63%) participated. Reexaminations were done to select suitable participants into the trial. Men had blood pressure 150-179/95-109 mm Hg and the active group (n=406) was treated with thiazides, alpha-methyldopa and propranolol versus untreated controls (n=379). Cox regression analysis was used for statistical analyses. There was no trend towards reduction in total mortality by treatment. A nominally significant increase in risk of death at first myocardial infarction was observed in the trial treatment group across the follow-up period, HR=1.51 (1.01-2.25); (P=0.042). The excess risk developed rapidly during the first 15 years, but the gap between the groups diminished to a large extent during the next 15 years, but the curves stayed at a certain distance for the last 10 years. Cerebrovascular death tended to be non-significantly reduced, HR=0.85 (0.52-1.41). Drug treatment of mild hypertensive men initiated in the 1970s did not reduce mortality at first MI or total mortality. However, during the period (late 1980s and whole 1990s), when large changes in hypertension treatment practices occurred into regimes with more use of combination therapies including metabolically neutral drugs at lower doses, beneficial effects on MI mortality could be observed.

  19. Managing geotechnical risk on US design-build transport projects

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Awarding design-build (DB contracts before a complete subsurface investigation is completed, makes mitigating the risk of differing site conditions difficult, if not impossible. The purpose of the study was to identify effective practices for managing geotechnical risk in DB projects, and it reports the results of a survey that included responses from 42 of 50 US state departments of transportation and a content analysis of DB requests for proposals from 26 states to gauge the client’s perspective, as well as 11 structured interviews with DB contractors to obtain the perspective from the other side of the DB contract.  A suite of DB geotechnical risk manage tools is presented based on the results of the analysis. Effective practices were found in three areas: enhancing communications on geotechnical issues before final proposals are submitted; the use of project-specific differing site conditions clauses; and expediting geotechnical design reviews after award. The major finding is that contract verbiage alone is not sufficient to transfer the risk of changed site conditions. The agency must actively communicate all the geotechnical information on hand at the time of the DB procurement and develop a contract strategy that reduces/retires the risk of geotechnical uncertainty as expeditiously as possible after award.

    1995-08-01

    The geotechnical data from the underground excavations at the WIPP are interpreted and presented in this Geotechnical Analysis Report. The data are used to characterize conditions, assess design assumptions, and understand and predict the performance of the underground excavations during operations. The data are obtained as part of a regular monitoring program. The format of the Geotechnical Analysis Report was selected to meet the needs of several audiences. This report focuses on the geotechnical performance of the various underground facilities including the shafts, shaft stations, access drifts, experimental rooms, and waste storage areas. The results of excavation effects, investigations, stratigraphic mapping, and other geologic studies are also included. The report provides an evaluation of the geotechnical aspects of performance in the context of the relevant design criteria and also describes the techniques used to acquire the data and the performance history of the instruments. The depth and breadth of the evaluation for the different underground facilities varies according to the types and quantities of data that are available, and the complexity of the recorded geotechnical responses

  2. Geotechnical properties of Egyptian collapsible soils

    Full Text Available The risk of constructing structures on collapsible soils presents significant challenges to geotechnical engineers due to sudden reduction in volume upon wetting. Identifying collapsible soils when encountered in the field and taking the needed precautions should substantially reduce the risk of such problems usually reported in buildings and highways. Collapsible soils are those unsaturated soils that can withstand relatively high pressure without showing significant change in volume, however upon wetting; they are susceptible to a large and sudden reduction in volume. Collapsible soils cover significant areas around the world. In Egypt, collapsible soils were observed within the northern portion of the western desert including Borg El-Arab region, and around the city of Cairo in Six-of-October plateau, and Tenth-of-Ramadan city. Settlements associated with development on untreated collapsible soils usually lead to expensive repairs. One method for treating collapsible soils is to densify their structure by compaction. The ongoing study presents the effect of compaction on the geotechnical properties of the collapsible soils. Undisturbed block samples were recovered from test pits at four sites in Borg El-Arab district, located at about 20 km west of the city of Alexandria, Egypt. The samples were tested in both unsoaked and soaked conditions. Influence of water inundation on the geotechnical properties of collapsible soils was demonstrated. A comparative study between natural undisturbed and compacted samples of collapsible soils was performed. An attempt was made to relate the collapse potential to the initial moisture content. An empirical correlation between California Bearing Ratio of the compacted collapsible soils and liquid limit was adopted. The presented simple relationships should enable the geotechnical engineers to estimate the complex parameters of collapsible soils using simple laboratory tests with a reasonable accuracy.

    1993-01-01

    The US Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the permanent disposal of high-level nuclear waste. The three media that were selected for study were basalt (WA), salt (TX, LA, MS, UT), and tuff (NV). Preliminary Exploratory Shaft Facilities (ESF) designs were prepared for seven candidate salt sites, including bedded and domal salt environments. A bedded-salt site was selected in Deaf Smith County, TX for detailed site characterization studies and ESF Final Design. Although Congress terminated the Salt Repository Program in 1988, Final Design for the Deaf Smith ESF was completed, and much of the design rationale can be applied to subsequent deep repository shafts. This paper presents the rationale for the geotechnical instrumentation that was designed for construction and operational performance monitoring of the deep shafts of the in-situ test facility. The instrumentation design described herein can be used as a general framework in designing subsequent instrumentation programs for future high-level nuclear waste repository shafts

    Few Norwegian data are available on the importance of physical activity with regard to mortality. Our objective was to study mortality in light of leisure time physical activity and smoking. Men born in the period 1923-1932 were included in the Oslo Study in 1972-1973 and then investigated again in 2000. A total of 5738 men were included in the analyses. Physical activity was registered as self-reported number of hours at low and high intensity, as well by the Gothenburg question on the degree of leisure activity (sedentary, low, moderate, high). Cox regression analysis was used for statistical computation. After 12 years, men who reported a moderate amount of activity (approximately 30 minutes per day six times per week of low or high activity) in the year 2000 had a 40% lower mortality rate than the physically inactive (the reference group). A change in activity level in older age was independently associated with a risk of death. The Gothenburg question on amount of activity gave the same predictive information value as smoking. Our data indicate that there is a dose-response relationship between the degree of physical activity and early death. An increase in activity was just as strongly associated with reduced mortality as quitting smoking. Based on these data, physical activity should be recommended as a daily habit.

    1988-01-01

    The Illinois State Geological Survey (ISGS) has completed an extensive four-year exploration of the area near Fermi National Accelerator Laboratory (Fermilab) at Batavia, 30 miles west of Chicago. The comprehensive investigation was conducted to locate the most suitable site for construction and operation of the Superconducting Super Collider (SSC) - a 20-trillion electron volt (TeV) subatomic particle accelerator. Underlying the proposed site in northeastern Illinois, between 250 and 600 feet deep, are the Galena and Platteville dolomites - strong, stable, nearly impermeable bedrock. To confirm that these bedrock units are suitable for construction of the SSC, ISGS geologists designed a four-year study including test drilling, rock sampling and analysis, geophysical logging, hydrogeologic studies, and seismic exploration. Initially, the study covered parts of six counties. Subsequent research focused on successively smaller areas until the final stage of test drilling in spring 1986 concentrated on a proposed corridor for the SSC tunnel. From 1984 to 1986, thirty 3-inch-diameter test holes were drilled and more than 2 miles of bedrock core was recovered for stratigraphic description and geotechnical analysis

    This panel of the 1990 Summer Study examines the potential contribution of energy efficiency in buildings to environmental protection. The Panel also covers other aspects of the relationship between building efficiency and the environment, including indoor air quality, radon exposure, and urban heat island effects. Global environmental risks, growing interest in market-based environmental regulation, and the integration of environmental and energy planning have focused attention on energy efficiency as a low-cost pollution prevention strategy. This combination of factors is making public concern over the environment a driving force for improvements in energy efficiency. The environmental issues that are related to air pollution include the group of problems that have been in the public consciousness for two decades: acid rain, urban smog, ozone depletion, and general outdoor air pollution. Indoor air quality is also an air pollution problem. Whereas indoor air pollution causes direct health impacts on occupants of the space in question, outdoor air pollution affects others, often at remote locations, in ways that are more difficult to quantify. There is an immediacy to the indoor pollution issue that has important policy implications. The papers in the indoor air quality and radon sessions focus on several of the important issues in this area. For these conference proceedings, individual papers are processed separately for the Energy Data Base

    Environmental pollution is a negative consequence of the development process, and many countries are grappling with this phenomenon. As a developing country, Iran is not exempt from this rule, and Iran pays huge expenditures for the consequences of pollution. The aim of this study was to analyze the long- and short-run impact of air pollution, along with other health indicators, on private and public health expenditures. This study was an applied and developmental study. Autoregressive distributed lag estimating models were used for the period of 1972 to 2014. In order to determine the co-integration between health expenditures and the infant mortality rate, fertility rate, per capita income, and pollution, we used the Wald test in Microfit version 4.1. We then used Eviews version 8 to evaluate the stationarity of the variables and to estimate the long- and short-run relationships. Long-run air pollution had a positive and significant effect on health expenditures, so that a 1.00% increase in the index of carbon dioxide led to an increase of 3.32% and 1.16% in public and private health expenditures, respectively. Air pollution also had a greater impact on health expenditures in the long term than in the short term. The findings of this study indicate that among the factors affecting health expenditures, environmental quality and contaminants played the most important role. Therefore, in order to reduce the financial burden of health expenditures in Iran, it is essential to reduce air pollution by enacting and implementing laws that protect the environment.

  10. Recent advancements in the geotechnical characterization of oil sands tailings

    Sharp, J. [Conetec, Richmond, BC (Canada)

    2010-07-01

    The technical aspects of soft oil sands tailings in-situ geotechnical site investigations were discussed. Geotechnical studies are conducted to determine containment structure stability as well as to determine volumetric and mass balances. The results of the studies are used in tailings management plans and construction activities. Flow penetrometers, field vane shear tests, and Gamma-CPTu tests are used in in-situ oil sands tailings geotechnical studies in order to determine pore pressure dissipation, and measure shear strength. Ball penetration tests are conducted to determine tailings strength. Methods of interpreting data from the tests were presented, and data from the tests were also compared and evaluated. Recommended procedures for strength screening were presented. Statistical methods for determining tailings behaviour types were outlined. The study showed that Gamma-CPTu data can be used to obtain reasonable preliminary estimates of solids and fines when combined with tailings behaviour type analyses. tabs., figs.

    Using the Oslo Study of 1972-1973, we wished to compare the long-term mortality pattern up to 40 years, in both the healthy cardiovascular groups at supposedly high and low risk, and in some groups having cardiovascular disease at screening. At the screening, 16,203 (63% of those invited) men aged 40-49 years participated. Study groups were identified by means of questionnaires regarding diseases, blood pressure and measurements of total cholesterol, triglycerides and glucose. We identified six groups: very high cholesterol, very high blood pressure, very high glucose, non-smoking with non-elevated such risk factors, from a randomized diet and antismoking trial, and a randomized drug treatment in mild-to-moderate hypertension. Statistical analyses were by Cox regression analysis, with Kaplan-Meier graphs. The supposedly low-risk group had a total mortality of one-third of other groups, such as: men with hypertension, diabetes or hypercholesterolemia, or those whom participated in the two trials. Between these latter groups, we found 2-5 years of difference in their median survival time, but their absolute risk stayed at rather high levels through all the years, with the median remaining a lifetime that was 3-8 years shorter than the men whom were free of known cardiovascular disease, diabetes or hypertension. The long-term preventive effects on total mortality seem large, if the levels of the classical risk factors of blood pressure, total cholesterol and glucose can be adequately controlled, concurrently with a non-smoking behavior. The study indicated that non-smoking and a low total cholesterol value were the most important contributors to extended survival. © 2015 the Nordic Societies of Public Health.

    The Mexicali Valley (northwestern Mexico), situated in the southern part of the San Andreas fault system, is an area with high tectonic deformation, recent volcanism, and active seismicity. Since 1973, fluid extraction, from the 1500-3000 m depth range, at the Cerro Prieto Geothermal Field (CPGF), has influenced deformation in the Mexicali Valley area, accelerating the subsidence and causing slip along the traces of tectonic faults that limit the subsidence area. Detailed field mapping done since 1989 (González et al., 1998; Glowacka et al., 2005; Suárez-Vidal et al., 2008) in the vicinity of the CPGF shows that many subsidence induced fractures, fissures, collapse features, small grabens, and fresh scarps are related to the known tectonic faults. Subsidence and fault rupture are causing damage to infrastructure, such as roads, railroad tracks, irrigation channels, and agricultural fields. Since 1996, geotechnical instruments installed by CICESE (Centro de Investigación Ciéntifica y de Educación Superior de Ensenada, B.C.) have operated in the Mexicali Valley, for continuous recording of deformation phenomena. Instruments are installed over or very close to the affected faults. To date, the network includes four crackmeters and eight tiltmeters; all instruments have sampling intervals in the 1 to 20 min range. Instrumental records typically show continuous creep, episodic slip events related mainly to the subsidence process, and coseismic slip discontinuities (Glowacka et al., 1999, 2005, 2010; Sarychikhina et al., 2015). The area has also been monitored by levelling surveys every few years and, since the 1990's by studies based on DInSAR data (Carnec and Fabriol, 1999; Hansen, 2001; Sarychikhina et al., 2011). In this work we use data from levelling, DInSAR, and geotechnical instruments records to compare the subsidence caused by anthropogenic activity and/or seismicity with slip recorded by geotechnical instruments, in an attempt to obtain more information

    Examinations for parietal cell antibody (PCA) were performed on 1334 subjects of the Adult Health Study (AHS), Hiroshima, during a 1-year period. Findings revealed PCA in 112 subjects (8.4%), but no difference in frequency was noted by sex. The positive rate was significantly higher in those age 50 or over. No correlation was noted between estimated A-bomb exposure dose and PCA frequency. PCA was found in 58 of the 502 cases presenting achlorhydria on tubeless gastric analysis, and particularly in the age 50 and over group, PCA was demonstrated in 43 of the 302 subjects presenting achlorhydria. PCA was detected in 11 of 152 subjects with low, serum pepsinogen levels and in 20 of 123 subjects with high levels. The frequency of positive PCA in subjects presenting achlorhydria and abnormal (low or high) serum pepsinogen levels was 19 in 100, higher than 7 in 106 in those subjects in whom gastric acidity and serum pepsinogen levels were both normal. The frequency of positive PCA was higher in patients diagnosed on upper gastrointestinal (GI) series as atrophic gastritis than in patients diagnosed as some other gastric disorder. PCA was negative in both of the two cases in whom a definite diagnosis of stomach cancer was established. However, in light of the finding of abnormal Diagnex Blue (DB) tests and positive PCA at a high frequency in the gastritis group and reports that gastritis provides the groundwork for stomach cancer, care should be taken in cases with findings of abnormal DB test, abnormal serum pepsinogen levels, and positive PCA.

    Construction, operation and decommissioning of nuclear waste repositories require sophisticated design, high-tech technical implementation and reliable performance assessment studies. Geotechnical methods have been applied in many research projects and tailored to the high standards of nuclear waste disposal. Exemplary the development of methods for the characterization of excavation damaged zones (EDZ) is discussed in this paper. Well known geotechnical and geophysical methods have been adapted to fulfil the requirements of essential high resolution in space and the necessity of long term observations. The achieved improvements in measurement techniques and data processing allow to describe the properties of the EDZ in detail. Scientist have accepted the challenge and fulfilled the special requirements of measuring, monitoring and modelling in the field of nuclear waste disposal. The newly developed methods should be checked for their applicability to other geotechnical problems in order to achieve more detailed results than with standard methods. (orig.)

    The preservation of natural environment has become a major concern, which affects nowadays a wide range of professionals from local communities administrators to natural resources managers (water, wildlife, flora, etc) and, in the end, to the consumers that we all are. Although totally ignored some fifty years ago, environmental geotechnics has become an emergent area of study and research which borders on the traditional domains, with which the geo-technicians are confronted (soil and rock mechanics, engineering geology, natural and anthropogenic risk management). Dedicated to experimental approaches (in-situ investigations and tests, laboratory tests, small-scale model testing), the Symposium fits in with the geotechnical domains of environment and transport of soil pollutants. These proceedings report some progress of developments in measurement techniques and studies of transport of pollutants in saturated and unsaturated soils in order to improve our understanding of such phenomena within multiphase environments. Experimental investigations on decontamination and isolation methods for polluted soils are discussed. The intention is to assess the impact of in-situ and laboratory tests, as well as small-scale model testing, on engineering practice. One paper is analysed in INIS data base for its specific interest in nuclear industry. The other ones, concerning the energy, are analyzed in ETDE data base

    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

    The challenges of installing underground terrestrial pipelines in regions with different morphologic characteristics include geotechnical problems such as superficial erosion or landslides. Due to this risk, TransPetro pipeline routes require continuous geologic-geotechnical inspections. This paper presented a methodology to detect possible risk of a geotechnical nature. The methodology uses remote sensing technology combined with geographic information system (GIS) geoprocessing. Aerial photography interpretation provides the visualization of risk features along pipelines and adjacent areas. The features of risk identified during photointerpretation are digitized and georeferenced, thereby facilitating geoprocessing. All data statistics are then analyzed in such a way to identify areas of high risk for geotechnical occurrence. The analyses allowed for the creation of a risk index, which was calculated to portions of 5 km of the pipeline. Risk was ranked in terms of high, medium and low susceptibility to geotechnical accidents. The geotechnical thematic mapping (GTM) was then created to predict geotechnical risk areas. The GTM was also incorporated into the 2002 standard for management of pipeline structural integrity due to its capability of classifying pipeline routes according to susceptibility to geological-geotechnical accidents. Inspection frequency can be established based on this classification. In addition to measuring the effectiveness of applied engineering techniques, the monitoring will also improve the understanding of the evolution of rights-of-way. 18 refs., 3 tabs.

    Abha is the capital of Asir province in Saudi Arabia. It is situated 2200 meters (7200 ft) above the sea level in the fertile mountains of the south-western Saudi Arabia. One of the most important structures of this region is Abha dam that acts as a barrier that impounds water or underground streams thereby retaining the ground water of the region. With the passage of time, various environmental factors such as ground movement, wind and changes in temperature may have significant effect on these various structure factors and may lead to invisible cracks and other structural defects. Because the dams and tunnels are prone to sudden collapse, there is potential great risk to lives of the people and significant economic loss in this area. The use of the ground penetrating radar (GPR) and electric resistivity techniques is a non-invasive scan and could assess the conditions of various built structures as well as the earth beneath or surrounding it. So the GPR system with appropriate types of antennas (1.5 GH, 1 GH, 400 MH and 100 MH) and electrical resistivity in one dimension (VES) and two dimensions (electrical profiling and imaging) is used in this work. This work aims to investigate the dam structure, developing cracks or areas of increased moisture. Also to study the surrounding areas to detect seepage from pond that may affect nearby buildings and the dam itself. It reveals that, the depth of water bearing layer ranges from 2 m to 10 m, where the three geoelectric layers are present. The first layer has resistivity values ranging from 44 Ω m-1200 Ω m with thickness ranging from 3 m to 18 m that is interpreted as the wadi deposits. The second layer having resistivity values from 11 Ω m to 137 Ω m is interpreted as the water saturated in the fractured basements. The third layer of resistivity values ranging from 2200 Ω m to 90,000 Ω m is interpreted as dry, massive basements. The GPR results provided internal images of the slab, showing its morphology, areas

    Geotechnical parameters are the basic parameters of geotechnical engineering design, while the geotechnical parameters have strong regional characteristics. At the same time, the spatial variability of geotechnical parameters has been recognized. It is gradually introduced into the reliability analysis of geotechnical engineering. Based on the statistical theory of geostatistical spatial information, the spatial variability of geotechnical parameters is quantitatively analyzed. At the same time, the evaluation of geotechnical parameters and the correlation coefficient between geotechnical parameters are calculated. A residential district of Tianjin Survey Institute was selected as the research object. There are 68 boreholes in this area and 9 layers of mechanical stratification. The parameters are water content, natural gravity, void ratio, liquid limit, plasticity index, liquidity index, compressibility coefficient, compressive modulus, internal friction angle, cohesion and SP index. According to the principle of statistical correlation, the correlation coefficient of geotechnical parameters is calculated. According to the correlation coefficient, the law of geotechnical parameters is obtained.

    Salt as a geologic medium has several attributes favorable to long-term isolation of waste placed in mined openings. Salt formations are largely impermeable and induced fractures heal as stress returns to equilibrium. Permanent isolation also depends upon the ability to construct geotechnical barriers that achieve nearly the same high-performance characteristics attributed to the native salt formation. Salt repository seal concepts often include elements of reconstituted granular salt. As a specific case in point, the Waste Isolation Pilot Plant recently received regulatory approval to change the disposal panel closure design from an engineered barrier constructed of a salt-based concrete to one that employs simple run-of-mine salt and temporary bulkheads for isolation from ventilation. The Waste Isolation Pilot Plant is a radioactive waste disposal repository for defense-related transuranic elements mined from the Permian evaporite salt beds in southeast New Mexico. Its approved shaft seal design incorporates barrier components comprising salt-based concrete, bentonite, and substantial depths of crushed salt compacted to enhance reconsolidation. This paper will focus on crushed salt behavior when applied as drift closures to isolate disposal rooms during operations. Scientific aspects of salt reconsolidation have been studied extensively. The technical basis for geotechnical barrier performance has been strengthened by recent experimental findings and analogue comparisons. The panel closure change was accompanied by recognition that granular salt will return to a physical state similar to the halite surrounding it. Use of run-of-mine salt ensures physical and chemical compatibility with the repository environment and simplifies ongoing disposal operations. Our current knowledge and expected outcome of research can be assimilated with lessons learned to put forward designs and operational concepts for the next generation of salt repositories.

    This dissertation presents a general methodology for the tasks of geological and geotechnical investigations, to be performed in the proposed sites for construction of nuclear Power Plants. In this work, items dealing with the standards applied to licensing of Nuclear Power Plants, with the selection process of sites and identification of geological and geotechnical parameters needed for the regional and local characterization of the area being studied, were incorporated. This dissertation also provides an aid to the writing of Technical Reports, which are part of the documentation an owner of a Nuclear Power Plant needs to submit to the Comissao Nacional de Energia Nuclear, to fulfill the nuclear installation licensing requirements. Moreover, this work can contribute to the planning of field and laboratory studies, needed to determine the parameters of the area under investigation, for the siting of Nuclear Power Plants.

  5. Geotechnical problems in the consolidation of buildings of historical interest

    Giovanni Calabresi

    2003-02-01

    Full Text Available The structural damages of ancient structures and monuments are very often due to differential settlements of their foundations, or to other effects of soil-structure interaction. A correct analysis of the damaging phenomena should be based on a sound geotechnical engineering approach, which requires expensive and long investigations on the mechanical characteristics of the foundation soils. However the last decade’s progress in construction technologies has offered a new and flexible kind of solutions to consolidate foundation structures that are often quicker and less expensive than a serious and complete geotechnical study. Therefore very often one of the above-mentioned solutions is simply adopted avoiding any previous study. The paper briefly illustrates the main negative effects of that approach, referring to some interesting case histories.

    A study of eolian activity was initiated to improve understanding of past climate change and the likely effect of wind on engineered protective barriers at the Hanford Site. Eolian features from a Holocene sand dune field located in the southeastern portion of the Hanford Site were investigated using a variety of field and laboratory techniques including stratigraphic examinations of hand-dug pits, textural and compositional analyses of dune sand and potential source detritus, and air photo interpretations. These investigations were undertaken to evaluate the provenance and eolian dynamics of the sand dunes. Interpretations of sand dune migration using archival air photo stereopairs document a 20% reduction in the volume of active sand dunes (measured from an approximate 15-km{sup 2} test area) between 1948 and 1987. Changes in annual precipitation appear to have influenced active dune migration strongly.

    1983-01-01

    The Waste Isolation Pilot Plant (WIPP) was authorized by Congress in 1980 as an unlicensed research and development (R and D) facility to demonstrate the safe disposal of radioactive wastes arising from the defense activities and programs of the United States. WIPP is now being constructed in southeast New Mexico, using salt beds about 655 m below the surface of the ground. Construction of the full WIPP facility will not commence until a preliminary underground excavation phase, called Site and Preliminary Design Validation (SPDV), is satisfactorily concluded in the summer of 1983. This SPDV program permits confirmation of subsurface geology, in drifts at planned facility depth that extend for 1555 m in a north-south direction, and in the two vertical shafts that provide access to these drifts. The subsurface studies are nearing completion, and it is therefore appropriate to draw conclusions regarding the geotechnical acceptability of the WIPP site. Four geotechnical elements are discussed: dissolution, deformation, hydrologic regime, and natural resources

    The geotechnical data from the underground excavations at the WIPP are interpreted and presented in this Geotechnical Analysis Report. The data are used to characterize conditions, assess design assumptions, and understand and predict the performance of the underground excavations during operations. The data are obtained as part of a regular monitoring program. They do not include data from tests performed by Sandia National Laboratories, the Scientific Advisor to the project in support of performance assessment studies. Geotechnical Analysis Reports have been prepared routinely and made available to the public since 1983. During the Site and Preliminary Design Validation Program, the Architect/Engineer for the project produced the reports on a quarterly basis to document the geomechanical performance during and immediately after construction of the underground. Upon completion of the constriction phase of the project in 1987, the reports have been prepared annually by the Management and Operating Contractor for the facility.

However, research has not identified a non-expensive and efficient method to map...... the fracture conditions of the various clay tills. Tests performed at the Danish Geotechnical Institute with large undisturbed columns of clay till show that there is a relation between the strength of the clay till and the hydraulic conductivity.

    1984-01-01

    The results of laboratory and in situ testing and test blasting, the observations made on a test embankment, and a description of actual construction practice associated with engineering studies for the management of uranium mill tailings at Elliot Lake, Ontario are presented. Relative density values inferred from standard penetration tests and cone penetrometer tests are shown to be inconsistent with relative density values determined from maximum and minimum void ratios. Some of the data contradicts existing correlations. The compressibility of in situ saturated tailings is presented in graphical form in terms of void ratio, vertical effective stress, and mean grain size. Hydraulic conductivity is shown to range over many orders of magnitude, depending on the void ratio. The observations on an instrumental test embankment are used to explain the appropriate selection of geotechnical parameters that gave good agreement between back-calculated and observed settlements. One-dimensional consolidation theory was found to be valid for the embankment case. It is necessary to account for changes in soil properties that occur during the consolidation process in order to obtain a good fit between back-calculated and observed settlements. The successful use of tailings sand for embankment construction is described. On the basis of normalized standard penetration resistance values, it is concluded that localized zones of saturated tailings may be prone to liquefaction under predicted earthquake loadings

    Many reports on Iraq proclaimed a rise in rates of death and disease since the Gulf War of January/February 1991. Several of the studies on nutritional status are not readily accessible, and few have been compared to identify secular trends. Here, 27 studies examining nutrition among Iraqi children in the 1990s are reviewed. Only five studies were found to be of comparable methodologic quality. These are analyzed to identify major trends in child nutrition between August 1991 and June 1999. Limitations of existing studies and recommendations for future studies are discussed.

    Additional data on geotechnical properties of MPG-1 sediments are presented. New data on Distal Abyssal Plain sediments east of the North Bermuda Rise (MPG-3N) indicates that this region has characteristics which compare favorably with MPG-1. The new permeability results are consistent with previous reported results for MPG-1 with a coefficient of permeability of approximately 10 -7 cm/sec. Preliminary results from MPG-3N indicate permeabilities comparable with those of MPG-1. Results are presented for thirty-seven triaxial compression tests on both undisturbed and remolded illite and smectite clays from the North Central Pacific (MPG-1). A preliminary set of repeated loading triaxial compression tests were performed on illite and smectite remolded clays from MPD-1. A device for anisotropic consolidation and triaxial compression has been developed which will allow the study of stress-strain behavior after anisotropic consolidation with zero lateral deformation. The long-term stress-strain behavior of deep sea sediments is the focus of a two-part testing program: Phase 1; room temperature studies, will be completed in Spring, 1980 and Phase 2; temperature effect studies, is now in the equipment development stage and should be underway by June, 1980. The testing portion of the laboratory Hole Closure study has been completed and most of the results are reported. A final technical report will be completed in June, 1980. The involvement of URI/MGL in this project covers five areas: site characterization, geotechnical analysis for platform foundation configuration, laboratory analysis of sediment-structure interaction development of in-situ vane shear apparatus and post-test analysis of recovered data relating to geotechnical behavior

    The Tuskegee study of untreated syphilis in the Negro male is the longest nontherapeutic experiment on human beings in medical history. The strategies used to recruit and retain participants were quite similar to those being advocated for HIV/AIDS prevention programs today. Almost 60 years after the study began, there remains a trail of distrust and suspicion that hampers HIV education efforts in Black communities. The AIDS epidemic has exposed the Tuskegee study as a historical marker for the legitimate discontent of Blacks with the public health system. The belief that AIDS is a form of genocide is rooted in a social context in which Black Americans, faced with persistent inequality, believe in conspiracy theories about Whites against Blacks. These theories range from the belief that the government promotes drug abuse in Black communities to the belief that HIV is a manmade weapon of racial warfare. An open and honest discussion of the Tuskegee Syphilis Study can facilitate the process of rebuilding trust between the Black community and public health authorities. This dialogue can contribute to the development of HIV education programs that are scientifically sound, culturally sensitive, and ethnically acceptable. Images p1500-a p1502-a p1503-a PMID:1951814

    Full Text Available In Iraq, especially in the last three decades, extensive developments have been evidenced in the regions of gypseous soils due to the need of construction of many numbers of strategic projects. Failure of different structures constructed on gypseous soil in various regions in Iraq have been noticed. For this purpose, three areas in northern Iraq were selected (Samarra, Tikrit and Baiji to study their geotechnical characteristics due to their high gypsum contents as well as many engineering problems are faced due to dissolution of gypsum. The experimental work involves testing of many properties such as: scanning electron microscopy (SEM, XRD, chemical, physical, compressibility, collapsibility, shear strength and suction. At low stress level, the test results revealed that, higher collapse potential (CP is recorded for Tikrit soil. While at low stress level, higher CP is obtained for Baiji soil indicating the increase in CP with decreasing gypsum content. Furthermore, the CP significantly increases with increasing stress level and soaking period at a particular stress level. According to severity classification of the collapse potential, Baiji soil is considered as moderate trouble to slight, while Tikrit soil is considered as trouble to moderate. After soaking, both soils become trouble. As well as, the results showed a reduction in Tikrit soil shear parameters ( φ and c after soaking period of 6 and 24 hrs as 12.2 to 9.2% in the internal friction angle and 91.5 to 94.2% in cohesion, respectively with respect to dry condition. Maximum total suction is measured for low consistency soils (liquid limit < 30% represented by Tikrit soil.

    2015-12-01

    The design process in geotechnical engineering requires the most accurate mapping of soil. The difficulty lies in the spatial variability of soil parameters, which has been a site of investigation of many researches for many years. This study analyses the soil-modeling problem by suggesting two effective methods of acquiring information for modeling that consists of variability from cone penetration test (CPT). The first method has been used in geotechnical engineering, but the second one has not been associated with geotechnics so far. Both methods are applied to a case study in which the parameters of changes are estimated. The knowledge of the variability of parameters allows in a long term more effective estimation, for example, bearing capacity probability of failure.

  9. Geotechnical Seismic Hazard Evaluation At Sellano (Umbria, Italy) Using The GIS Technique

    International Nuclear Information System (INIS)

    Capilleri, P.; Maugeri, M.

    2008-01-01

    A tool that has been widely-used in civil engineering in recent years is the geographic information system (GIS). Geographic Information systems (GIS) are powerful tools for organizing, analyzing, and presenting spatial data. The GIS can be used by geotechnical engineers to aid preliminary assessment through to the final geotechnical design. The aim of this work is to provide some indications for the use of the GIS technique in the field of seismic geotechnical engineering, particularly as regards the problems of seismic hazard zonation maps. The study area is the village of Sellano located in the Umbrian Apennines in central Italy, about 45 km east of Perugia and 120 km north-east of Rome The increasing importance attributed to microzonation derives from the spatial variability of ground motion due to particular local conditions. The use of GIS tools can lead to an early identification of potential barriers to project completion during the design process that may help avoid later costly redesign

  10. Geotechnical Parameters from Seismic Measurements: Two Field Examples from Egypt and Saudi Arabia

    KAUST Repository

    2016-03-18

    © 2016 EEGS. Geotechnical parameters were used to determine subsurface rock quality for construction purposes. We summarize the mathematical relationships used to calculate the geotechnical parameters from P- and S-wave velocities and density values. These relationships are applied to two field examples; the first is a regional seismic study in Egypt and the second is a 2-D seismic profile recorded in Saudi Arabia. Results from both field examples are used to determine the subsurface rock quality and locate zones that should be avoided during construction. We suggest combining all geotechnical parameters into one map using a normalized-weighted relation, which helps to locate the zones with high versus low rock quality for engineering purposes.

    1980-10-01

    This report is the result of a study which was the second part of an investigation, involving geotechnical analysis of soil samples from the West Valley burial site with respect to containment capability. In general, the results of standard engineering tests in soil from the West Valley site confirm the results predicted by testing performed during the first part of this study in 1977. The soil was submerged for almost 2 years and samples showed some increase in moisture content accompanied by a decrease in unit weight. Changes in the plasticity of the soil during this period were not significant, however, shrinkage limits were significantly different from earlier tests. This is probably attributable to a difference in testing procedure. The minimum developed cohesion for the soil in the wall Research Trench 111 was estimated to be 18.9kN/sq meters. In shallow softened soils the developed cohesion at failure under submerged conditions was estimated to be 2.54N/sq meters and failure under sudden drawdown conditions was estimated to be 4.79kN/sq meters

    Geotechnical and mineralogical characteristics of blue-green clays of the Harbour District existing inside the boundaries of Antalya Konyaalti Municipality were investigated with comprehensive field and laboratory tests. Today, building construction in this district is carried out without any prior qualified geotechnical investigations taking place. Undisturbed and disturbed soil specimens were taken from 12 drilled boreholes at 1.5 m intervals and down 30 m deep. Shelby tubes samples were retrieved and SPT were carried out in order to determine soil profile and geotechnical properties. After comparing the laboratory and field test results, it was observed that they were in agreement. Strength and compressibility characteristics of the soil were defined with the correlations using laboratory and field test results. Since the region has been formed of lagoon-sedimented clays, rock analysis was done on two specimens achieved from various depths along the soil profile. XRD analyses on eleven specimens were also conducted. Unconfined compressive strength (qu), undrained cohesion (Cu) and compression index (Cc) varies between 40 kN/m2, 7.0 kN/m2 and 90 kN/m2, 0.095 and 0.38, respectively. (author)

    This report presents the results of a scoping study to develop a methodology to produce desegregated greenhouse gas emission inventories for the devoved administrations of the UK. Separate greenhouse gas emission inventories were estimated for England, Scotland, Wales and Northern Ireland for the years 1990 and 1995. The gases reported are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and SF{sub 6}. The estimates are consistent with the 1997 UK Greenhouse Gas Inventory and hence the UNFCCC reporting guidelines. Some emissions mainly mobile and offshore sources could not be allocated to any region, so an extra unallocated category was used to report these. Where possible the same methodology was used to calculate the regional emissions as for the UK Inventory. The study showed that the distribution of regional greenhouse gas emissions expressed as global warming potentials in 1995 were: England 75.5%, Scotland, 11.4%; Wales 6.4%; Northern Ireland 3.1%: unallocated, 4%. Following this scoping study, it is intended to publish annually disaggregated inventories for each year from 1990 for England, Scotland, Wales and Northern Ireland, in addition to the UK Greenhouse Gas Inventory. 50 refs., 6 figs., 16 tabs., 2 apps.

    1982-04-01

    The results of a literature survey on the stability of excavated hard rock caverns are presented. The objective of the study was to develop geotechnical criteria for the design of compressed air energy storage (CAES) caverns in hard rock formations. These criteria involve geologic, hydrological, geochemical, geothermal, and in situ stress state characteristics of generic rock masses. Their relevance to CAES caverns, and the identification of required research areas, are identified throughout the text. This literature survey and analysis strongly suggests that the chief geotechnical issues for the development and operation of CAES caverns in hard rock are impermeability for containment, stability for sound openings, and hydrostatic balance.

    This study is concerned with a preliminary engineering evaluation of borehole facilities for nuclear waste disposal in shales. Some of the geotechnical properties of Pierre, Rhinestreet, and typical illite shale have been collected. The influence of a few geotechnical properties on strength and deformation of host material is briefly examined. It appears that Pierre shale is very unstable and requires support to prevent collapse. Typical illite shale is more stable than Rhinestreet shale, although it undergoes relatively more deformation. 16 refs., 5 figs., 3 tabs

    1977-07-01

    The purpose of the investigation was to monitor changes in the labour market situation for dentists who received authorization to practise dentistry in Norway during the years 1972-1975. Data was collected by postal questionnaire during April/May of the year following authorization, except for the 1972 cohort, which was contacted the second year after authorization. A 92-95 per cent response rate was achieved using one follow-up (Table 1). The percentage of respondents who waited 8 weeks or more to acquire a job in dentistry increased from 15 for those authorized in 1972 to 36 for the 1975 group (Table 3). The proportion of dentists who took paid employment other than dentistry, increased from just over 3 per cent for the 1973 to 14 per cent for the 1975 cohort (Table 4). This development has occured despite a decrease in the number of dentists receiving authorization each year and has resulted in a limited emigration of dentists. It is suggested that the favourable supply of dentists in relation to existing demand for dental services presents an ideal opportunity for attempting to solve dental health problems which have received inadequate attention in the past.

    Most of the scientific tasks of the institute were carried out with the Tandem accelerator. The investigations with polarized particles in the field of nuclear physics were particularly successful in explaining the reaction mechanisms in the presence of resonances. In heavy-ion physics, the study of intermediary structures below the Coulomb wall gave clear indications on α-particle states. Meson effects with g factors of excited nuclear states could even be found in local investigations. The Lambshift source, developed in the institute, was newly set up for the installation on the Tandem based on the experience gained on the test model. As the energy and radiation time of the Erlangen accelerator is not sufficient for many experiments, experiments were carried out externally on accelerators in Karlsruhe and Hamburg on the one hand, and, on the other hand, laboratory experiments on the Moessbauer effect and with atomic beams were intensified.

    Marls and marly limestone deposits cover most of Northern Jordan, where Amman City and its suburbs are located. These deposits serve as foundations for most buildings and roads as well as fill material for structural back filling, especially road bases and sub-bases. The present study aims at investigating the geotechnical characteristics and mineral composition of the marl units of these deposits through field investigations and laboratory testing. Using X-ray diffraction technique along with chemical analysis, representative samples of marl horizons were tested for mineral composition, and for a set of index and geotechnical properties including: specific gravity, grain size, Atterberg limits, Proctor compaction and shear strength properties. The test results show a positive linear relationship as expected between the clay content and both liquid and plastic limits. The tests results also show an inverse linear relationship between the clay content and the maximum dry density in both standard and modified compaction. This is attributed to the adsorption of water by the clay minerals. The relationship is more prominent in the case of modified compaction test. The results also indicate a similar relationship for the angle of internal friction. No clear correlation between cohesion and clay content was apparent.

The stream 'Waste management - Waste Site technology' discusses legal requirements and technical alternatives, especially in view of many upcoming closures of landfill sites and associated surface sealing, as well as technical reports of case studies and developments. The contribution 'Ultimate storage of radioactive waste' illustrates the wider dimensions to geotechnical questions. Between the streams of 'Remediation Techniques' and 'Land Recycling/Land Management' a panel discussion 'From Brownfield Remediation to Land Management' is taking place. The aim is to discuss the way forward and the need to take up the opportunity for future town planning as well as the design of conversion sites and expansive former mining areas. Representatives of authorities involved and project participants have submitted their statements in advance to the following question: 1.) status of remediation - research and practice 2.) what practical significance is attributed to different remediation techniques for the remediation of brownfields? 3.) modern town planning/redevelopment of former mining areas - spatial planning - real estate economy - financing models for redeveloping land - which parameters/instruments work?

    1991-07-01

    This document provides both functional and physical descriptions of a conceptual high-level waste management system defined as a Basic MRS System. Its purpose is to provide a basis for required system computer modeling and system studies initiated in FY 1990 under the Systems Integration Program of the Office of Civilian Radioactive Waste Management Office (OCRWM). Two specific systems studies initiated in FY 1990, the Reference System Performance Evaluation and the Aggregate Receipt Rate Study, utilize the information in this document. The Basic MRS System is the current OCRWM reference high-level radioactive wastes repository system concept. It is designed to accept 3000 MTU per year of spent fuel and 400 equivalent MTU per year of high-level wastes. The Basic MRS System includes a storage-only MRS that provides for a limited amount of commercial spent fuel storage capacity prior to acceptance by the geologic repository for disposal. This document contains both functional descriptions of the processes in the waste management system and physical descriptions of the equipment and facilities necessary for performance of those processes. The basic MRS system contains all system components, from the waste storage facilities of the waste generators to the underground facilities for final disposal of the wastes. The major facilities in the system are the waste generator waste storage facilities, an MRS facility that provides interim storage wastes accepted from the waste generators, a repository facility that packages the wastes and then emplaces them in the geologic repository, and the transportation equipment and facilities for transporting the waste between these major facilities

    To describe the global burden of disease due to road traffic accidents in Brazil and federated units in 1990 and 2015. This is an analysis of secondary data from the 2015 Global Burden of Disease study estimates. The following estimates were used: standardized mortality rates and years of life lost by death or disability, potential years of life lost due to premature death, and years of unhealthy living conditions. The Mortality Information System was the main source of death data. Underreporting and redistribution of ill-defined causes and nonspecific codes were corrected. Around 52,326 deaths due to road traffic accidents were estimated in Brazil in 2015. From 1990 to 2015, mortality rates decreased from 36.9 to 24.8/100 thousand people, a reduction of 32.8%. Tocantins and Piauí have the highest mortality risks among the federated units (FU), with 41.7/100 and 33.1/100 thousand people, respectively. They both present the highest rates of potential years of life lost due to premature deaths. Road traffic accidents are a public health problem. Using death- or disability-adjusted life years in studies of these causes is important because there are still no sources to know the magnitude of sequelae, as well as the weight of early deaths. Since its data are updated every year, the Global Burden of Disease study may provide evidence to formulate traffic security and health attention policies, which are guided to the needs of the federated units and of different groups of traffic users.

  13. Electroweak symmetry breaking studies at the pp colliders of the 1990's and beyond

    International Nuclear Information System (INIS)

    1989-01-01

    Within the conventional framework of a spontaneously broken gauge theory, general principles establish that the electroweak symmetry is broken by a new force that may be weak with associated new quanta below 1 TeV or strong with quanta above 1 TeV. The SSC parameters, √s = 40 TeV and L = 10 33 cm/sup /minus/2/s/sup /minus/1/, define a minimal facility with assured capability to observe the signals of symmetry breaking by a strong force above 1 TeV. Foreseeable luminosity upgrades would not be able to compensate a much lower collider energy for these physics signals. If the strong WW scattering signal were seen at the SSC in the 1990's it would provide a clear imperative for a collider with the physics reach of the ELOISATRON to begin detailed studies of the new force and quanta early in the next century. 35 refs., 7 figs., 4 tabs

    In the present article, the results of geotechnical monitoring of A-147 automobile road “Dzhubga-Sochi” are given. Some sections of the automobile road suffered from the landslide adjustment movements; it resulted in many deformations of the retaining structures, the damages of the roadbed and ground crawling over the retaining walls. The observation data made it possible to specify the borders of the active landslide and to form a forecast of the landslide activity in the sections of the automobile roads. Due to monitoring being carried out, there was substantiated the necessity to correct the service forms and records connected with the automobile road reconstruction.

    CERN Document Server

    Ameratunga, Jay; Das, Braja M

    2016-01-01

    This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations a...

  20. Probabilistic approaches for geotechnical site characterization and slope stability analysis

    CERN Document Server

    Cao, Zijun; Li, Dianqing

    2017-01-01

    This is the first book to revisit geotechnical site characterization from a probabilistic point of view and provide rational tools to probabilistically characterize geotechnical properties and underground stratigraphy using limited information obtained from a specific site. This book not only provides new probabilistic approaches for geotechnical site characterization and slope stability analysis, but also tackles the difficulties in practical implementation of these approaches. In addition, this book also develops efficient Monte Carlo simulation approaches for slope stability analysis and implements these approaches in a commonly available spreadsheet environment. These approaches and the software package are readily available to geotechnical practitioners and alleviate them from reliability computational algorithms. The readers will find useful information for a non-specialist to determine project-specific statistics of geotechnical properties and to perform probabilistic analysis of slope stability.

    Gastrointestinal (GI) neoplasms are among the most common cancers in Iran. This study aimed to measure annual trends in mortality rates from GI cancers in Iran between 1990 and 2015. This study was part of an ongoing study termed the 'National and Subnational Burden of Diseases' study in Iran. Data used in this study was obtained from the Iranian Death Registration System (1995 to 2010) and from 2 major cemeteries in Tehran (1995 to 2010) and Isfahan (2007 to 2010). All-cause mortality rates were estimated using the spatio-temporal model and the Gaussian process regression model. Age-standardized mortality rates (ASMR) per 100 000 person-years was calculated using data from Iran and the standard world population for comparison. Among GI cancers, gastric cancer represented the leading cause of mortality followed by cancers of the esophagus, liver, and colorectal cancers with the ASMR of 20.5, 5.8, 4.4, and 4.0 per 100 000 persons-years, respectively, between 1990 and 2015. While a decreasing trend occurred in mortality of esophageal, gastric, and colorectal cancers, particularly in the recent decade, we recorded an upward pattern and steady rise in mortality rates from liver, pancreatic, and gallbladder cancers during the study period. The ASMR of all studied causes were enhanced by advancing age and were found to be more prominent in adults aged 50 or older. Among all age-groups, higher death rates were detected in males versus females for all studied cancers except for gallbladder and biliary tract cancers. Gastric cancer mortality is still high and death rates from several other GI cancers are increasing in the nation. Interventions for cancer prevention, early detection, and access to high quality cancer treatment services are needed to reduce GI cancer burden and death rates in Iran and in the region. © 2018 The Author(s).

  2. Pore water pressures and slope stability: a joint geophysical and geotechnical analysis

    International Nuclear Information System (INIS)

    2008-01-01

    Slope stability is influenced by many factors, among which are subsoil structure and pore water pressure distribution. This paper presents a multi-disciplinary approach for the determination of these two factors and for the construction of a reliable model of the subsoil for the slope stability analysis. The case of a clay slope located in the Southern Apennines (Italy) is presented and discussed. Geophysical imaging (2D electrical resistivity tomography—ERT), in situ geotechnical monitoring (measurements of pore pressures and horizontal displacements) and laboratory geotechnical tests (for the determination of index, hydraulic and mechanical properties of soils) have been carried out. The comparison and the integration between ERT images and direct observations of the material extracted from boreholes have allowed us to reconstruct the subsoil stratigraphy with continuity. Thus, a reliable 2D model of the subsoil has been obtained, with well-defined boundaries on which it has been possible to apply appropriate hydraulic conditions. This geotechnical model has been used for studying the pore water pressure distribution and for analysing how the hydraulic boundary conditions—among which rain events—influence the slope stability. Our findings demonstrate the powerful skill of the ERT, if integrated with borehole data, to generate an accurate subsoil model. It is also evident that geophysical imaging can be a source of ambiguity and misjudgement if interpreted without a comparison with geotechnical data

    The PGS reservoir has had several issues with seepage and seepage-related phenomena since its construction in 1953. In 1958, a major sinkhole on the upstream side of the near chaining 6+00 was found. Ontario Hydro decided to draw down the reservoir, repair the sinkhole area immediately and undertake a major grouting program. This paper presented a study of geotechnical issues associated with the PGS reservoir dyke. This study was launched to investigate the potential remedial solutions to maintain the long term safety of the dyke and to determine the ways to expand the energy generating capability of the facility. In this paper, the recent Hatch findings on the geology, construction history, hydrogeological setting and seepage evaluation were presented. Next, the assessment of future measures for seepage control and energy enhancement opportunities were discussed.

    The clinical records of 23 dogs (1990-1999) with histopathologically confirmed bacterial meningoencephalomyelitis were evaluated retrospectively. No breed, age, sex, or weight predisposition was found. All the dogs presented with clinical signs of a brain lesion, whereas 5 of 23 had neck pain. Pyrexia was detected in 11 of 23 dogs on admission. CBCs revealed neutrophilic leucocytosis in 7 of 21 dogs and thrombocytopenia in 3 of 21 dogs. The serum chemistry profiles were abnormal in 15 of 21 dogs. The results of cerebrospinal fluid (CSF) analysis were abnormal in 13 of 14 dogs and aerobic CSF culture was positive for bacteria in 1of 8 samples. At postmortem examination, the lesions were localized to the central nervous system. Escherichia coli, Streptococcus, and Klebsiella spp were the most frequently isolated bacteria from cultures collected at postmortem examination. Twelve papers reporting 51 total clinical cases of canine bacterial meningoencephalomyelitis were reviewed. The clinical signs and results of the CBC, serum chemistry, blood culture, and CSF analysis were collated and compared with those of this study. The results of the CSF analysis in this study were similar to those in the literature. CSF cultures documented in the literature were positive for Staphylococcus, Pasteurella. Actinomyces, Nocardia spp, and various anaerobic species including Peptostreptococcus, Eubacterium, and Bacteroides spp.

  10. Geotechnical engineering for ocean waste disposal. An introduction

    Science.gov (United States)

    Lee, Homa J.; Demars, Kenneth R.; Chaney, Ronald C.; ,

    1990-01-01

    As members of multidisciplinary teams, geotechnical engineers apply quantitative knowledge about the behavior of earth materials toward designing systems for disposing of wastes in the oceans and monitoring waste disposal sites. In dredge material disposal, geotechnical engineers assist in selecting disposal equipment, predict stable characteristics of dredge mounds, design mound caps, and predict erodibility of the material. In canister disposal, geotechnical engineers assist in specifying canister configurations, predict penetration depths into the seafloor, and predict and monitor canister performance following emplacement. With sewage outfalls, geotechnical engineers design foundation and anchor elements, estimate scour potential around the outfalls, and determine the stability of deposits made up of discharged material. With landfills, geotechnical engineers evaluate the stability and erodibility of margins and estimate settlement and cracking of the landfill mass. Geotechnical engineers also consider the influence that pollutants have on the engineering behavior of marine sediment and the extent to which changes in behavior affect the performance of structures founded on the sediment. In each of these roles, careful application of geotechnical engineering principles can contribute toward more efficient and environmentally safe waste disposal operations.

    Danwei as a cornerstone of Chinese urban society has received great research attention. The relationship between the Danwei and psychiatric patients, however, remains unclear. This article aims to shed light on the subject with an integrated micro-macro approach. It introduces a historical understanding of mental health in urban China under the "economic state in transition" framework. A detailed case study in clinical sociology is provided to reveal the many social factors affecting the experience of a schizophrenic patient and his significant others. A changing role of the Danwei is hypothesized and validated with qualitative data. The Danwei was shown to have changed significantly before the mid-1990s, yet it still played a major role in urban workers' lives, including those of psychiatric patients, and even more so in people's expectations. This lends support to the need for a more responsive public policy to address various social issues brought about by economic reform, with the learning of worldwide experiences including "community care," "social support" and "social rehabilitation." Implications for social research, policymaking and professional practice are discussed.

    1990-09-01

    The geotechnical Field Data and Analysis Report documents the geomechanical data collected at the Waste Isolation Pilot Plant up to June 30, 1989 and describes the conditions of underground openings from July 1, 1988 to June 30, 1989. The data is required to understand performance during operations and does not include data from tests performed to support performance assessment. In summary, the underground openings have performed in a satisfactory manner during the reporting period. This analysis is based primarily on the evaluation of instrumentation data, in particular the comparison of measured convergence with predictions, and the observations of exposed rock surfaces. The main concerns during this period have been the deterioration found in Site Preliminary Design Validation Test Rooms 1 and 2 and some spalling found in Panel 1. 14 refs., 45 figs., 11 tabs

    Document available in extended abstract form only. The issue of the disposal of radioactive waste is one of the most pressing challenges of our age, for which, in most countries, the deep repository concept is generally considered to be the most suitable final solution. In order to make such a repository both safe and reliable, intensive research is underway worldwide. The construction of physical models is one approach to the study of the engineered barriers for deep geological repositories; one such experiment, Mock-Up-CZ, has been performed at the Centre of Experimental Geotechnics, CTU in Prague. The Mock-Up-CZ experiment simulated the vertical placement of a container with radioactive waste, an approach that is in line with the Swedish KBS-3 system. The physical model consisted of a barrier made up of bentonite blocks, powdered bentonite backfill, a heater and hydration and monitoring systems. The whole experiment was enclosed in a cylindrical box, whose construction was able to withstand high pressure due to bentonite swelling. A number of sensors (monitoring changes in temperature, pressure and moisture) were placed inside the bentonite barrier. The basic material used in the experiment consisted of a mixture of Czech bentonite from the Rokle deposit (85%), quartz sand (10%) and graphite (5%). The first phase of the experiment commenced on 7 May 2002, during which the heater was switched on, with no water input. After 6 months the second phase commenced in which water was introduced through the hydration system. This phase ended on 2nd January 2006 when the heater was switched off. After allowing time for cooling, the dismantling phase commenced (30 January 2006). After a further one and a half months (17 March 2006) the dismantling of the experimental vessel was completed. Post-decommissioning analysis continued until the end of 2007. Dismantling and post-decommissioning analysis were carried out according to a very detailed plan which included not only

    1988-01-01

    From 1984 through 1986, geologists from the Illinois State Geological Survey (ISGS) conducted a thorough field investigation in northeastern Illinois to determine whether the surface and subsurface geology would be suitable for constructing the U.S. Department of Energy's 20-TeV (trillion electron volt) particle accelerator - the Superconducting Super Collider (SSC). The third and final stage of test drilling in 1986 concentrated on a specific corridor proposed for the racetrack-shaped SSC that would circle deep below the surface of Kane, Kendall, and Du Page Counties. The main objective was to verify that bedrock lying under the region satisified the site criteria for construction of a 10-foot-diameter tunnel to hold the particle accelerator and the superconducting magnets, large chambers to house the laboratories and computers for conducting and recording experiments, and shafts to provide access to the subterranean facilities. Thirteen test holes, ISGS S-18 through S-30, were drilled to depths ranging from 398.2 to 646.6 feet. The field team recovered 5675 feet of bedrock core and 212 samples of glacial drift (sand, clay, gravel) for laboratory analyses and recorded on-site data that establish the thickness, distribution, lithology (composition), and other properties of the rocks lying under the study area

  17. Site study plan for Upper Aquifer Hydrology Clusters, Deaf Smith County Site, Texas: Surface-based geotechnical field program: Preliminary draft

    1988-01-01

    As part of site characterization studies, at the Deaf Smith County site, Texas, 15 wells at 5 locations will be completed in the Ogallala Formation and Dockum Group. The purposes of the wells, which are called Upper Aquifer (2) establish background hydrologic and water quality conditions, (3) provide analysis, (4) monitor responses of the shallow hydrologic system to site activities and nearby pumpage for irrigation, (5) collect water samples from both saturated and unsaturated materials to help define recharge rates and ground-water flow patterns, (6) monitor variations on water quality, and (7) define ground-water resources near the site. The test wells will be installed during a 14-month period starting about 1-1/2 years after site characterization activities begin.

    1987-12-01

    This site study plan describes the Exploratory Shaft Facilities (ESF) Design Foundation Boreholes field activities to be conducted during early stages of Site Characterization at the Deaf Smith County, Texas, site. The field program has been designed to provide data useful in addressing information/data needs resulting from federal/state/local regulations, and repository program requirements. Approximately 50 foundation boreholes will be drilled within the ESP location to provide data necessary for design of the ESF and to satisfy applicable shaft permitting requirements. Soils and subsurface rock will be sampled as the foundation boreholes are advanced. Soil samples or rock core will be taken through the Blackwater Draw and Ogallala Formations and the Dockum Group. Hydrologic testing will be performed in boreholes that penetrates the water table. In-situ elastic properties will be determined from both the soil strata and rock units along the length of the boreholes. Field methods/tests are chosen that provide the best or only means of obtaining the required data. The Salt Repository Project (SRP) Networks specify the schedule under which the program will operate. Drilling will not begin until after site ground water baseline conditions have been established. The Technical Field Services Contractor is responsible for conducting the field program of drilling and testing. Samples and data will be handled and reported in accordance with established SRP procedures. A quality assurance program will be utilized to assure that activities affecting quality are performed correctly and that the appropriate documentation is maintained. 25 refs., 10 figs., 6 tabs

    Four countries, Botswana, Cote d'Ivoire, Ghana and Zimbabwe, were chosen as cases to study the impact of national health policies on national health status in sub-Saharan Africa. Through a conceptual framework that covers health problem identification, policy formulation and implementation procedures, the study examined national translations of Primary Health Care (PHC) and Health for All by the Year 2000 (HFA/2000) strategies. A series of government measures, taken between 1980-1986 for health policy development and implementation in these countries, were treated as policy determinants of national health outcomes for the period ending 1990. The impact of these determinants on national health status was then analyzed through a comparative description and documentation of observable patterns and trends in infant mortality rates (IMR), under-5 mortality rates (U5MR) and life expectancy. Policy guidelines from PHC and HFA/2000 were used in conjunction with the respective per capita Gross National Products to categorize the four cases. Based on these guidelines, Botswana was ranked high, both in terms of policy development and the level of economic development, while Zimbabwe ranked high in terms of policy development but relatively low in economic terms. Cote d'Ivoire ranked high on economic development but low with regard to its policy framework. Ghana was at the other end of the spectrum, ranking low both in terms of its policy development and its economic performance. The comparative analysis revealed that Botswana and Zimbabwe performed better than Cote d'Ivoire and Ghana on the three outcome indicators. Despite Cote d'Ivoire's superior level of economic development, its health status fell behind that of Zimbabwe and even Ghana. The study concluded that policies formulated and implemented in accordance with key PHC principles could account for improvements in national health status. Since the end of the study period (1990), there have been significant political

    1988-01-01

    The planned permanent underground repository for non-heat-generating wastes in the former Konrad iron-ore mine is now in the final stages of the plan approval procedures. The deadline for the final stages of the plan approval procedures for the Gorleben salt dome is approaching. It is time to give an account of what has been accomplished in the geotechnical field. The BGR has developed a complex geotechnical stability analysis that takes into account the requirements of permanent storage and the objectives required for the protection of the biosphere. This stability analysis is based on the following considerations: Owing to the complexity of the boundary conditions, a cavity intended for a permanent repository can be demonstrated to be safe only by a combination of studies and simulations. These studies must integrate engineering geology, geotechnics, rock mechanics, statics, monitoring of the conditions in the repository, and mining expertise. (orig.) With 27 figs

    It is performed the first geotechnical synthesis for La Arganosa Formation, the Cretaceous lithostratigraphic unit with very low geomechanical quality under the urban core of Oviedo; it also configures a major regional aquifer. In this study, geotechnical parameters of identification and condition, as well as physical and hydraulic ones, are compiled, statistically treated and interpreted. They were obtained from about 400 laboratory tests and more than 250 field tests around the city. The unit, of detrital origin, is bounded at the bottom and top by limestone lithologies, and is made up of soils and very soft rocks in alternating granular and cohesive layers. It discusses the main properties that define its geotechnical behavior: particle size distribution, plasticity, strength, compactness, consistency, compressibility, expansivity, collapsibility, permeability, and chemical aggressiveness of the materials and water. Furthermore, same numerical values are provided for reference forward guidance for future research to develop on this formation. (Author) 31 refs.

    Construction, operation and decommissioning of nuclear waste repositories require sophisticated design, high-tech technical implementation and reliable performance assessment studies. Geotechnical methods have been applied in many research projects and tailored to the high standards of nuclear waste disposal. Exemplary the development of methods for the characterization of excavation damaged zones (EDZ) is discussed in this paper. Well known geotechnical and geophysical methods have been adapted to fulfil the requirements of essential high resolution in space and the necessity of long term observations. The achieved improvements in measurement techniques and data processing allow to describe the properties of the EDZ in detail. Scientist have accepted the challenge and fulfilled the special requirements of measuring, monitoring and modelling in the field of nuclear waste disposal. The newly developed methods should be checked for their applicability to other geotechnical problems in order to achieve more detailed results than with standard methods. (orig.)

  10. Geotechnical modeling of high-level nuclear waste disposal by rock melting

    1981-12-01

    A new strategy has been developed for the geotechnical modeling of nuclear waste disposal by rock melting (DRM). Three seeparate tasks were performed to reach this objective: a review of the four scenarios which have been proposed for DRM, to date; an evaluation of computer-based numerical models which could be used to analyze the mechanical, thermal, and hydraulic processes involved in DRM; and a critical review of rock mass properties which are relevant to the design and safety of waste disposal by rock melting. It is concluded that several geotechnical aspects of DRM can be studied realistically with current state-of-the-art model capabilities and knowledge of material properties. The next step in the feasibility study of DRM should be a best-estimate calculation of the four cavity-melt and canister-burial concepts. These new analyses will indicate the most critical areas for subsequent research

    Geotechnical site works are comprehensive, and they constitute the first step of the construction process. This study performs data mining of geotechnical works and analyzes the database for the root causes of accidents. The Occupational Safety and Health Administration (OSHA) was chosen for the 1984-2013 time frame with 247 cases. Descriptive statistical analyses were performed to discuss variables such as the end use of the work, project type and cost, soil type and condition, type and degree of injury, cause and type of accident, unsafe acts, and occupation and union status of the victim. The results showed that these accidents have a high frequency of recurrence and have a high severity level (54.3% fatalities). In addition, a total of 838 violations were recorded with penalties reaching 5 million US dollars. This study emphasizes that project-specific countermeasures should be taken regarding the root causes of accidents, leading to vigorous strategies to develop safety measures.

    2018-02-21

    The atrocities in Syria have been covered in the four general medical weekly journals in the USA and the UK. Medical journal articles addressing political determinants of public health have rightly described and criticised the international community's failure to enforce humanitarian law while urging global bodies of power to ensure protection of civilians and civilian infrastructure and medical services. Discussions of the political influences on health of people in the occupied Palestinian territory (West Bank and Gaza Strip) seem to be considered politically out-of-bounds by some medical journals. This study used a keyword-based search to explore patterns of publication about the occupied Palestinian territory and Israel by four large US and European medical journals. The four highest ranked, peer-reviewed, international medical journals were searched: The Journal of the American Medical Association (JAMA), The New England Journal of Medicine (NEJM), The Lancet, and The British Medical Journal (BMJ). Searches were conducted between Sept 1 and Sept 6, using each journal's search engine with the keywords "Gaza", "West Bank" and the stems "Palestin*" and "Israel*" in all fields for the period Jan 1, 1990, to Sept 6, 2016. News and commentary articles were included in the findings. The searches found the term "Palestin*" in 49 articles from the two US journals (32 in JAMA; 17 in NEJM) and 694 articles in the two UK journals (236 in The Lancet; 458 in BMJ). "Israel*" was found in 840 articles in US journals (386 in JAMA; 454 in NEJM) and in 2972 articles in UK journals (1388 in The Lancet; 1584 in BMJ). "West Bank" was found in nine articles in US journals (nine in JAMA; none in NEJM) and in 297 articles from the UK (211 in The Lancet; 86 in BMJ). "Gaza" was found in 18 articles in US journals (15 from JAMA; three from NEJM) and in 487 articles in UK journals (324 in The Lancet; 166 in BMJ). Compared with the two US-based medical journals, the UK journals published

    Full Text Available Abstract Background Although preventable, tetanus still claims tens of thousands of deaths each year. The patterns and distribution of mortality from tetanus have not been well characterized. We identified the global, regional, and national levels and trends of mortality from neonatal and non-neonatal tetanus based on the results from the Global Burden of Disease Study 2015. Methods Data from vital registration, verbal autopsy studies and mortality surveillance data covering 12,534 site-years from 1980 to 2014 were used. Mortality from tetanus was estimated using the Cause of Death Ensemble modeling strategy. Results There were 56,743 (95% uncertainty interval (UI: 48,199 to 80,042 deaths due to tetanus in 2015; 19,937 (UI: 17,021 to 23,467 deaths occurred in neonates; and 36,806 (UI: 29,452 to 61,481 deaths occurred in older children and adults. Of the 19,937 neonatal tetanus deaths, 45% of deaths occurred in South Asia, and 44% in Sub-Saharan Africa. Of the 36,806 deaths after the neonatal period, 47% of deaths occurred in South Asia, 36% in sub-Saharan Africa, and 12% in Southeast Asia. Between 1990 and 2015, the global mortality rate due to neonatal tetanus dropped by 90% and that due to non-neonatal tetanus dropped by 81%. However, tetanus mortality rates were still high in a number of countries in 2015. The highest rates of neonatal tetanus mortality (more than 1,000 deaths per 100,000 population were observed in Somalia, South Sudan, Afghanistan, and Kenya. The highest rates of mortality from tetanus after the neonatal period (more than 5 deaths per 100,000 population were observed in Somalia, South Sudan, and Kenya. Conclusions Though there have been tremendous strides globally in reducing the burden of tetanus, tens of thousands of unnecessary deaths from tetanus could be prevented each year by an already available inexpensive and effective vaccine. Availability of more high quality data could help narrow the uncertainty of tetanus

  14. Geotechnical investigations of the PEP site

    The purpose of this paper is to summarize the general nature of the geology and rock and soil formations of the PEP site as they relate to the design and construction of the project; to describe site investigation programs and to catalog the geotechnical information presently available about the site. The recently-completed investigation of subterranean conditions around the PEP ring when coupled with previous surveys gives us a good understanding of what to expect with regard to tunneling, undertaking larger underground excavations and constructing research halls are the interaction areas. It bears out the predictions made in Jacobs and Associates' report of 1973; i.e., that the ring housing construction is classified as soft-ground tunneling and that large underground openings, such as region 10 and the injection junction structures, will require great attention to support. A shield or shields will probably be required. On the positive side, the site affords very good conditions for soft-ground tunneling. Water will be a problem in some areas, but not an unsolvable one. The possibility of encountering lethal or explosive gases, almost always the case in tunneling in California's coastal formations, exists but has not been ascertained. Finally, no reasons to change current cost estimates or schedules have merged from the investigation. 13 refs., 1 fig

    Epidemiologists have used case-control studies to investigate enteric disease outbreaks for many decades. Increasingly, case-control studies are also used to investigate risk factors for sporadic (not outbreak-associated) disease. While the same basic approach is used, there are important differences between outbreak and sporadic disease settings that need to be considered in the design and implementation of the case-control study for sporadic disease. Through the International Collaboration on Enteric Disease “Burden of Illness” Studies (the International Collaboration), we reviewed 79 case-control studies of sporadic enteric infections caused by nine pathogens that were conducted in 22 countries and published from 1990 through to 2009. We highlight important methodological and study design issues (including case definition, control selection, and exposure assessment) and discuss how approaches to the study of sporadic enteric disease have changed over the last 20 years (e.g., making use of more sensitive case definitions, databases of controls, and computer-assisted interviewing). As our understanding of sporadic enteric infections grows, methods and topics for case-control studies are expected to continue to evolve; for example, advances in understanding of the role of immunity can be used to improve control selection, the apparent protective effects of certain foods can be further explored, and case-control studies can be used to provide population-based measures of the burden of disease.

    Full Text Available Soil treatment and improvement is commonly performed in the field of geotechnical engineering. Methods and materials to achieve this such as soil stabilization and mixing with cementitious binders have been utilized in engineered soil applications since the beginning of human civilization. Demand for environment-friendly and sustainable alternatives is currently rising. Since cement, the most commonly applied and effective soil treatment material, is responsible for heavy greenhouse gas emissions, alternatives such as geosynthetics, chemical polymers, geopolymers, microbial induction, and biopolymers are being actively studied. This study provides an overall review of the recent applications of biopolymers in geotechnical engineering. Biopolymers are microbially induced polymers that are high-tensile, innocuous, and eco-friendly. Soil–biopolymer interactions and related soil strengthening mechanisms are discussed in the context of recent experimental and microscopic studies. In addition, the economic feasibility of biopolymer implementation in the field is analyzed in comparison to ordinary cement, from environmental perspectives. Findings from this study demonstrate that biopolymers have strong potential to replace cement as a soil treatment material within the context of environment-friendly construction and development. Moreover, continuing research is suggested to ensure performance in terms of practical implementation, reliability, and durability of in situ biopolymer applications for geotechnical engineering purposes.

  17. Nonparametric Monitoring for Geotechnical Structures Subject to Long-Term Environmental Change

    2011-01-01

    Full Text Available A nonparametric, data-driven methodology of monitoring for geotechnical structures subject to long-term environmental change is discussed. Avoiding physical assumptions or excessive simplification of the monitored structures, the nonparametric monitoring methodology presented in this paper provides reliable performance-related information particularly when the collection of sensor data is limited. For the validation of the nonparametric methodology, a field case study was performed using a full-scale retaining wall, which had been monitored for three years using three tilt gauges. Using the very limited sensor data, it is demonstrated that important performance-related information, such as drainage performance and sensor damage, could be disentangled from significant daily, seasonal and multiyear environmental variations. Extensive literature review on recent developments of parametric and nonparametric data processing techniques for geotechnical applications is also presented.

    1980-01-01

    Studies of geotechnical properties for the Sub-seabed Disposal Program have been oriented toward sediment characterization related to effectiveness as a containment media and determination of detailed engineering behavior. Consolidation tests of the deeper samples in the North Pacific clays indicate that the sediment column is normally consolidated. The in-situ coefficient of permeability (k) within the cored depth of 25 meters is relatively constant at 10 -7 cm/sec. Consolidated undrained (CIU) triaxial tests indicate stress-strain properties characteristic of saturated clays with effective angles of friction of 35 0 for smectite and 31 0 for illite. These results are being used in computer modeling efforts. Some general geotechnical property data from the Bermuda Rise are also discussed

  19. Effects of biochar amendment on geotechnical properties of landfill cover soil.

    2015-06-01

    Biochar is a carbon-rich product obtained when plant-based biomass is heated in a closed container with little or no available oxygen. Biochar-amended soil has the potential to serve as a landfill cover material that can oxidise methane emissions for two reasons: biochar amendment can increase the methane retention time and also enhance the biological activity that can promote the methanotrophic oxidation of methane. Hydraulic conductivity, compressibility and shear strength are the most important geotechnical properties that are required for the design of effective and stable landfill cover systems, but no studies have been reported on these properties for biochar-amended landfill cover soils. This article presents physicochemical and geotechnical properties of a biochar, a landfill cover soil and biochar-amended soils. Specifically, the effects of amending 5%, 10% and 20% biochar (of different particle sizes as produced, size-20 and size-40) to soil on its physicochemical properties, such as moisture content, organic content, specific gravity and pH, as well as geotechnical properties, such as hydraulic conductivity, compressibility and shear strength, were determined from laboratory testing. Soil or biochar samples were prepared by mixing them with 20% deionised water based on dry weight. Samples of soil amended with 5%, 10% and 20% biochar (w/w) as-is or of different select sizes, were also prepared at 20% initial moisture content. The results show that the hydraulic conductivity of the soil increases, compressibility of the soil decreases and shear strength of the soil increases with an increase in the biochar amendment, and with a decrease in biochar particle size. Overall, the study revealed that biochar-amended soils can possess excellent geotechnical properties to serve as stable landfill cover materials. © The Author(s) 2015.

  20. Brief Overlook on the Occupational Accidents Occurring During the Geotechnical Site Works

    Akboğa Kale, Özge; Eskişar, Tuğba

    2017-10-01

    The aim of this paper is to evaluate occupational accidents reported in geotechnical site works. Variables of the accidents are categorized as the year and month of accidents, the technical codes used for defining the scope of work trades, end use and project type and cost, nature and cause of accidents, occupation of the victims and finally the cause of fatality. As a result, it is seen that the majority of victims were construction laborers or in special trade constructors who were working on a new project or new additions to an existing project. The geotechnical phase of the projects was whether excavation, landfill, sewer-water treatment, pipeline construction, commercial building or road construction. As the outcomes of the study it is evaluated that excavation, trenching and installing pipe or pile driving were the main causes of the accidents while trench collapse, struck by a falling object / projectile and wall collapse were the main causes of fatality. Moreover, it is established that more than half of the fatalities were due to asphyxia followed by fracture. These findings show that accidents occurred in geotechnical works do not only have high frequency but also high severity. This study emphasizes project specific countermeasures should be taken regarding the nature, cost and importance of the project and the occupation variabilities working on the project.

    The "Alamo" project is a retrospective analysis of 14,854 patients diagnosed of breast cancer between 1990 and 1997 in 50 Spanish hospitals. Alamo I (AI) consisted of 4,532 patients diagnosed with breast cancer between 1990 and 1993. Data were collected in 2000. Alamo II (AII) consisted of 10,322 patients diagnosed between 1994 and 1997. Data were collected in 2003. At presentation, there were (AI vs. AII) 17.6% vs. 24.3% at stage I; 55.5% vs. 53.1% at stage II; 18.7% vs. 15% at stage III; 7.2% vs. 5.9 at stage IV. Median age was 57 (AI) vs. 58 years (AII) and 65.9% vs. 67.2% (AI vs. AII) were post-menopausal. Firstline treatment for disease stages I, II and III was surgery in 91% of patients in both studies. Breast conserving surgery rate increased from 20.2% (AI) to 32.7% (AII). Adjuvant systemic treatments were administered to 87.6% (AI) and 92.8% (AII) of patients. Recurrence rate diminished from 36.6% (AI) to 22.5% (AII) and the 9-year survival rate increased from 63.2% (95% CI: 61.5-64.9) to 70.1% (95% CI: 68.5-71.8). Breast cancer outcomes in Spain have improved from 1990-1993 to 1994-1997, likely because of breast cancer screening program implementation and new therapies.

    This paper reports the results of the first geomechanical laboratory experiments carried out on the polluted submarine clayey sediments of the Mar Piccolo in Taranto (South of Italy). The study had to face with extreme difficulties for the very soft consistency of the sediments and the contaminants. The mineralogy, composition and physical properties of the sediments were analysed, along with their compression and shearing behaviour. The investigation involved sediments up to about 20 m below the seafloor, along three vertical profiles in the most polluted area of the Mar Piccolo, facing the Italian Navy Arsenal. The experimental results were used to derive a preliminary geotechnical model of the site, necessary for the selection and design of the most sustainable in situ mitigation solutions. Moreover, the experimental data reveal that the clayey sediments of the most polluted top layer do not follow the classical geotechnical correlations for normally consolidated deposits. This seems to open interesting perspectives about the effects of pollutants on the geotechnical behaviour of the investigated sediments.

    Full Text Available Expansive soil spreads in Iraq and some countries of the world. But there are many problems can be occurred to the structures that built on, so we must study the characteristics of these soils due to the problems that may be caused to these structures which built on these kinds of soil and then study the methods of treatment. The present study focuses on improving the geotechnical properties of expansive soils by treating it Metakaolin(M. Metakaolin (M has never been used before as an improvement material for stabilizing the expansive soil . Metakaolin is a pozzolanic material. It’s obtained by calcination of kaolinite clay at temperatures from 700°C to 800°C. Kaolin chemical composition is basically aluminous silicates hydrates associated with Mn, Fe, Ca, K, Na. Its crystal has a lattice structure of tetrahedral and octahedral layers with interplanar distance of 7.2 Å. The soil used in the present study can be classified according to the Unified Soil Classification System as clay with high plasticity (CH .

    Full Text Available This study illustrates the application of polymer material for clayey soil stabilization. The article will focus on studying the strength behavior of the clayey soils reinforced with homogenously polymer fiber. In the current research, “polypropylene” was selected as polymer material to reinforce the natural clay soil. This polymer fiber was added to the clayey soil with four different percentages of (0, 1.5, 3, and 5% by weight of soil. Various tests with different polymer contents were performed to study the effect of using such a polymer as a stabilizing agent on geotechnical properties of clay. As the fiber content increases, the optimum moisture content (OMC is increased while the specific gravity decreases. For Atterberg’s limits, the results indicated increasing liquid limit and plasticity index while decreasing plastic limit with increase in polymer content. The outcomes of the tests also reflected a considerable improvement in the unconfined compressive strength with noticeable improvement in the shear strength parameter (undrained shear strength, cu of the treated soils. The undrained shear strength obtained from treated soil with 5% polymer addition is more than three times that of the untreated soil. With an increase in polymer content, the consolidation parameters (Compression index Cc and recompression index Cr decreases. Finally, the benefit of the reinforcement is increased with increasing polymer fiber content.

    Surfactants are often used as a cleaning agent for restoration of oil-contaminated soil. However the effect of surfactant on the geotechnical properties of soil is not clearly understood. In this study, the effects of surfactant on silty soil were investigated for consistency index, compaction, permeability and shear strength. Sodium dodecyl sulfate (SDS) was used in this study to prepare the surfactant-treated soil. Our results showed that the soil with added surfactant exhibited a decrease in liquid and plastic limit values. Maximum dry densities increased and optimum moisture contents decreased as contents of added surfactant were increased. The presence of surfactant assists the soil to achieve maximum density at lower water content. The addition of surfactant decreased the permeability of soil from 6.29 x 10 -4 to 1.15 x 10 -4 ms -1 . The shear strength of soil with added surfactant was examined using the undrained unconsolidated triaxial tests. The results showed that the undrained shear strength, Cu was significantly affected, decreased from 319 kPa to 50 kPa for soil with 20 % of added surfactant. The results of this study showed that the presence of surfactant in soil can modify the mechanical behaviour of the soil. (author)

    Knowledge of how arctic plant communities will respond to change has been largely derived from plot level experimental manipulation, not from trends of decade time scale environmental observations. This study documents plant community change in 330 marked plots at 33 sites established during the International Biological Program near Barrow, Alaska in 1972. Plots were resampled in 1999, 2008 and 2010 for species cover and presence. Cluster analysis identified nine plant communities in 1972. Non-metric multidimensional scaling (NMS) indicates that plant communities have changed in different ways over time, and that wet communities have changed more than dry communities. The relative cover of lichens increased over time, while the response of other plant functional groups varied. Species richness and diversity also increased over time. The most dramatic changes in the cover of bryophytes, graminoids and bare ground coincided with a lemming high in 2008. (letter)

    Responding to the widespread need for the geotechnical community to discuss instrumentation for nuclear waste repositories, a meeting was held December 2 and 3, 1981, in Denver, Colorado. This report gives the group's consensus recommendations to aid in making decisions for development of instrumentation for future repository work. The main conclusions of the working group meeting were as follows: (1) monitoring of geotechnical parameters in nuclear waste repositories will be necessary to meet licensing requirements; (2) currently available instruments are underdeveloped for this monitoring; (3) research and development to provide adequate instrumentation will need to be performed under federal sponsorship by national laboratories, universities, contractors, and consultants; and (4) a NASA-type reliability program is needed to meet the quality assurance, durability, calibration, and time schedule demands of geotechnical instrumentation development. This will require significant financial commitments from the federal sector

    Nowadays, the focus on more ecological means of material and persons transport is still higher. Big loads can be transported on railways more effectively and with lower environment impact than on roads. The geotechnical structures are inherent parts of railway infrastructure, such as embankments, sides of notches and, of course, tunnels, foundation constructions of buildings or pillars of bridges and the others geotechnical constructions (e.g. retaining walls, culverts, transition area of bridges). By train pass, vibrations are caused and these vibrations are relayed to the soil. These vibrations can make adverse impact to surrounding objects and to technologies placed in. This so far uncared-for influence gets into the foreground by current trend of everyday life technical equipment increasing. The article introduces different kinds of geotechnical structures and the influence of by-passing railway transport on their constructions and surroundings. The data are evaluated in the amplitude and frequency domain.

    The framework of the Base Case and the High Case for 1990 for Ireland, related to the demand modules of the medium-term European Communities (EC) Energy Model, is described. The modules are: Multi-national Macre-economic Module (EURECA); National Input-Output Model (EXPLOR); and National Energy Demand Model (EDM). The final results of the EXPLOR and EDM are described; one set related to the Base Case and the other related to the High Case. The forecast or projection is termed Base Case because oil prices are assumed to increase with general price inflation, at the same rate. The other forecast is termed High Case because oil prices are assumed to increase at 5% per year more rapidly than general price inflation. The EXPLOR-EDM methodology is described. The lack of data on energy price elasticities for Ireland is noted. A comparison of the Base Case with the High Case is made. (MCW)

    2014-04-01

    Full Text Available An experimental work was undertaken to study the effect of rubber tires on the geotechnical properties of a dredged sediment, using a mixing ratio of large size. For comparison, two types of soil were studied (dredged sediment from Fergoug dam and Tizi Tuff from the north west of Algeria. Taking into account the high compressibility and the low water absorption of the rubber tires, grain size analysis, density, Atterberg limits analysis, chemical composition, direct shear tests, loading-unloading tests, modified Proctor and CBR tests are performed on the two soils and their mixtures with different scrap tire rubber (10, 20, 25 and 50%. The results show that liquid limits and plastic indexes decrease with the scrap tire rubber content and that the decrease is more significant for soil with high plasticity. Cohesion also decreases with scrap tire rubber content when the internal friction angle is vacillating. Compression and recompression indexes increase gradually with the scrap tire rubber content and the variation for compression index is more significant for the two soils. Compaction characteristics and CBR values decrease with scrap tire rubber content. The CBR values for W=3% are important compared to those with W=5% excepted for mixture with (75% tuff and 25% scrap tire rubber. The results show that the scrap tire rubber can be used as a reinforcement material for dredged soil, but with a content that should not highly affect the compressibility.

    Leachate is a hazardous liquid that poses negative impacts if leaks out into environments such as soil and ground water systems. The impact of leachate on the downgraded quality in terms of chemical characteristic is more concern rather than the physical or mechanical aspect. The effect of leachate on mechanical behaviour of contaminated soil is not well established and should be investigated. This paper presents the preliminary results of the effects of leachate on the Atterberg limit, compaction and shear strength of leachate-contaminated soil. The contaminated soil samples were prepared by mixing the leachate at ratiosbetween 0% and 20% leachate contents with soil samples. Base soil used was residual soil originated from granitic rock and classified as sandy clay soil (CS). Its specific gravity ranged between 2.5 and 2.64 with clay minerals of kaolinite, muscovite and quartz. The field strength of the studied soil ranged between 156 and 207 kN/m2. The effects of leachate on the Atterberg limit clearly indicated by the decrease in liquid and plastic limit values with the increase in the leachate content. Compaction tests on leachate-contaminated soil caused the dropped in maximum dry density, ρdry and increased in optimum moisture content, wopt when the amount of leachate was increased between 0% and 20%. The results suggested that leachate contamination capable to modify some geotechnical properties of the studied residual soils.

    A deterministic analytical procedure for ground motion modelling, combining both modal summation and mode coupling techniques has been implemented to obtain synthetic seismic signals at Russe, NE Bulgaria, due to one of the strongest Vrancea intermediate-depth earthquakes, which occurred during the last century, May 30, 1990. The frequency content of the synthetic signals in different frequency ranges, up to 1 and 2Hz, has been studied separately. The results of this study, i.e. time histories and related ground motions parameters, can be used for different earthquake engineering analyses, e.g. structural performance assessments. (author)

  1. Celebrating 25 years of Syncrude`s Geotechnical Review Board

    McKenna, G.

    1998-09-01

    An historical review of Syncrude`s Geotechnical Review Board (GRB) was presented, relating some of the successes of the Board over the past 25 years since its establishment. A list of the type of challenges faced by Syncrude where the GRB`s guidance and counselling proved to be critical, is also included. The GRB was established in the 1970s to help Syncrude manage its geotechnical-based risks and to enhance its long-range chances to be successful in oil sands mining. Mining oil sands was breaking new ground back then, consequently, the geotechnical risks were largely unknown and the potential of heavy financial losses were great. Under such circumstances making the right decisions in dealing with geotechnical risks was vital to success. The fact that 25 years later Syncrude is still operating on the basis of those earlier decisions and still relies heavily on the expertise of the Board for recommendations and guidance is a testimony to the value of the GRB to Syncrude`s operations. The GRB`s success is credited to the Board`s world-wide expertise, objectivity, focus on the big issues, risk-based approach and its excellent working partnership with Syncrude employees. Dragline mining and tailings management are the areas that benefited the most from the Board`s involvement, but the Board has been involved in every facet of geotechnical-based risk management. Some of the geotechnical challenges that the GRB has helped Syncrude to overcome include dam construction of muskeg foundation, heavy foundations on gassy and temperature-sensitive soils, coring and testing of gassy/expansive oil sands and haul roads, highwall design utilizing locked sands, winter construction of large fluid retaining embankments and characterization and management of fluid fine tailings. 3 refs., 1 graph, 3 figs.

    The report was prepared as one of a series of technical reports within a study of the groundwater movements around a repository for radioactive waste in the Precambrian bedrock of Sweden. This assessment is intended to provide basic geotechnical data for the analysis. These data include properties and conditions that are representative of the intact rock, the rock mass in general, and the groundwater regime. As there exist a considerable range in the mineralogy of potentially suitable plutonic rocks and since a specific site has not yet been selected, all of the parameters presented in this report must be based on presumptive geological and hydrogeological conditions. Where possible, data for two potential site areas, namely Oskarshamn and Forsmark, are presented. This report is divided into four parts. First, a brief description of the procedure for modelling groundwater movements is presented, along with a tabulation of the important parameters. Secondly, a description of the geological and hydrogeological conditions of the Fennoscandian shield, as well as of the two general site areas, is given. The final two sections of the report provide thermomechanical and geohydrological characteristics and properties of the host rock

    2017-01-01

    In the last 100 years, the global population has more than quadrupled to over seven billion people. At the same time, the demand for food and standard of living has been increasing which has amplified the global water use by nearly eight times from approximately 500 to 4000 cu km per yr from 1900 to 2010. With the increasing concern to sustain the growing population on Earth it is necessary to seek other approaches to ensure that our planet will have resources for generations to come. In recent years, the advancement of space travel and technology has allowed the idea of mining asteroids with resources closer to becoming a reality. During the duration of the internship at NASA Kennedy Space Center, several geotechnical tests were conducted on BP-1 lunar simulant and asteroid simulant Orgueil. The tests that were conducted on BP-1 was to practice utilizing the equipment that will be used on the asteroid simulant and the data from those tests will be omitted from report. Understanding the soil mechanics of asteroid simulant Orgueil will help provide basis for future technological advances and prepare scientists for the conditions they may encounter when mining asteroids becomes reality in the distant future. Distinct tests were conducted to determine grain size distribution, unconsolidated density, and maximum density. Once the basic properties are known, the asteroid simulant will be altered to different levels of compaction using a vibrator table to see how compaction affects the density. After different intervals of vibration compaction, a miniature vane shear test will be conducted. Laboratory vane shear testing is a reliable tool to investigate strength anisotropy in the vertical and horizontal directions of a very soft to stiff saturated fine-grained clayey soil. This test will provide us with a rapid determination of the shear strength on the undisturbed compacted regolith. The results of these tests will shed light on how much torque is necessary to drill

    To explore the burden of gout in the Nordic region, with a population around 27 million in 2015 distributed across six countries. We used the findings of the 2015 Global Burden of Diseases study to report prevalence and disability associated with gout in the Nordic region. From 1990 to 2015, the number of prevalent gout cases rose by 30% to 252 967 [95% uncertainty interval (UI) 223 478‒287 288] in the Nordic region. In 2015, gout contributed to 7982 (95% UI 5431‒10 800) years lived with disability (YLDs) in the region, an increase of 29% (95% UI 24‒35%) from 1990. While the crude YLD rate of gout increased by 12.9% (95% UI 7.8‒18.1%) between 1990 and 2015, the age-standardized YLD rate remained stable. Gout was ranked as the 63rd leading cause of total YLDs in the region in 2015, with the highest rank in men aged 55-59 years (38th leading cause of YLDs). The corresponding rank at the global level was 94. Of 195 countries studied, four Nordic countries [Greenland (2nd), Iceland (12th), Finland (14th), and Sweden (15th)] were among the top 15 countries with the highest age-standardized YLD rate of gout. The burden of gout is rising in the Nordic region. Gout's contribution to the total burden of diseases in the region is more significant than the global average. Expected increases in gout burden owing to population growth and ageing call for stronger preventive and therapeutic strategies for gout management in Nordic countries.

    Full Text Available Background: Cardiovascular diseases are viewed worldwide as one of the main causes of death.This study aims to report the burden of ischemic heart diseases (IHDs in Iran by using data of the global burden of disease (GBD study, 1990-2010. Materials and Methods: The GBD study 2010 was a systematic effort to provide comprehensive data to calculate disability-adjusted life years (DALYs for diseases and injuries in the world. Years of life lost (YLLs due to premature mortality were computed on the basis of cause-of-death estimates, using Cause of Death Ensemble model (CODEm. Years lived with disability (YLDs were assessed by the multiplication of prevalence, the disability weight for a sequel, and the duration of symptoms. A systematic review of published and unpublished data was performed to evaluate the distribution of diseases, and consequently prevalence estimates were calculated with a Bayesian meta-regression method (DisMod-MR. Data from population-based surveys were used for producing disability weights. Uncertainty from all inputs into the calculations of DALYs was disseminated by Monte Carlo simulation techniques. Results: The age-standardized IHDs DALY specified rate decreased 31.25% over 20 years from 1990 to 2010 [from 4720 (95% uncertainty interval (UI: 4,341-5,099 to 3,245 (95% UI: 2,810-3,529 person-years per 100,000]. The decrease were 38.14% among women and 26.87% among men. The age-standardized IHDs death specefied rate decreased by 21.17% [from 222 95% UI: 207-243 (to 175 (95% UI:152-190 person-years per 100,000] in both the sexes. The age-standardized YLL and YLD rates decreased 32.05% and 4.28%, respectively, in the above period. Conclusion: Despite decreasing age-standardized IHD of mortality, YLL, YLD, and DALY rates from 1990 to 2010, population growth and aging increased the global burden of IHD. YLL has decreased more than IHD deaths and YLD since 1990 but IHD mortality remains the greatest contributor to disease burden.

    Full Text Available Economic growth and green environment has a direct relation with health, habitat and well being of our society which depends largely on the natural environment. But on the other side the society is neglecting and often ignoring the benefits that nature provides for economic prosperity. This paper studies the role of environment in economic growth, the role of environmental policy in achieving improved environmental results, closely examine the evidence of decoupling production from environmental damages and discuss decoupling in the context of global economy. In order to study these aspects, we explored our comparative research with special reference to selected eight OECD nations namely-France, Germany, Ireland, Japan, Portugal, Turkey, UK and USA with coverage period of 1990-2010. The selection of the countries is based on their prominence in industrialised world and their close economic bounding with each other over a considerable period. The coverage period in the study is 20 years because some of the emission data are available till 2013 and some only up to 2010. In order to do a comparative research on various dimensions we take in to our study period between1990-2010.

    Deborah Carvalho Malta

    Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: Noncommunicable diseases (NCDs are the leading health problem globally and generate high numbers of premature deaths and loss of quality of life. The aim here was to describe the major groups of causes of death due to NCDs and the ranking of the leading causes of premature death between 1990 and 2015, according to the Global Burden of Disease (GBD 2015 study estimates for Brazil. DESIGN AND SETTING: Cross-sectional study covering Brazil and its 27 federal states. METHODS: This was a descriptive study on rates of mortality due to NCDs, with corrections for garbage codes and underreporting of deaths. RESULTS: This study shows the epidemiological transition in Brazil between 1990 and 2015, with increasing proportional mortality due to NCDs, followed by violence, and decreasing mortality due to communicable, maternal and neonatal causes within the global burden of diseases. NCDs had the highest mortality rates over the whole period, but with reductions in cardiovascular diseases, chronic respiratory diseases and cancer. Diabetes increased over this period. NCDs were the leading causes of premature death (30 to 69 years: ischemic heart diseases and cerebrovascular diseases, followed by interpersonal violence, traffic injuries and HIV/AIDS. CONCLUSION: The decline in mortality due to NCDs confirms that improvements in disease control have been achieved in Brazil. Nonetheless, the high mortality due to violence is a warning sign. Through maintaining the current decline in NCDs, Brazil should meet the target of 25% reduction proposed by the World Health Organization by 2025.

    Summary Background With recent improvements in vaccines and treatments against viral hepatitis, an improved understanding of the burden of viral hepatitis is needed to inform global intervention strategies. We used data from the Global Burden of Disease (GBD) Study to estimate morbidity and mortality for acute viral hepatitis, and for cirrhosis and liver cancer caused by viral hepatitis, by age, sex, and country from 1990 to 2013. Methods We estimated mortality using natural history models for acute hepatitis infections and GBD’s cause-of-death ensemble model for cirrhosis and liver cancer. We used meta-regression to estimate total cirrhosis and total liver cancer prevalence, as well as the proportion of cirrhosis and liver cancer attributable to each cause. We then estimated cause-specific prevalence as the product of the total prevalence and the proportion attributable to a specific cause. Disability-adjusted life-years (DALYs) were calculated as the sum of years of life lost (YLLs) and years lived with disability (YLDs). Findings Between 1990 and 2013, global viral hepatitis deaths increased from 0·89 million (95% uncertainty interval [UI] 0·86–0·94) to 1·45 million (1·38–1·54); YLLs from 31·0 million (29·6–32·6) to 41·6 million (39·1–44·7); YLDs from 0·65 million (0·45–0·89) to 0·87 million (0·61–1·18); and DALYs from 31·7 million (30·2–33·3) to 42·5 million (39·9–45·6). In 2013, viral hepatitis was the seventh (95% UI seventh to eighth) leading cause of death worldwide, compared with tenth (tenth to 12th) in 1990. Interpretation Viral hepatitis is a leading cause of death and disability worldwide. Unlike most communicable diseases, the absolute burden and relative rank of viral hepatitis increased between 1990 and 2013. The enormous health loss attributable to viral hepatitis, and the availability of effective vaccines and treatments, suggests an important opportunity to improve public health.

    Full Text Available In this work, we investigate the temporal evolution of ground deformation affecting the ocean-reclaimed lands of the Shanghai (China megacity, from 2007 to 2016, by applying the Differential Synthetic Aperture Radar Interferometry (DInSAR technique known as the Small BAseline Subset (SBAS algorithm. For the analysis, we exploited two sets of non-time-overlapped synthetic aperture radar (SAR data, acquired from 2007 to 2010, by the ASAR/ENVISAT (C-band instrument, and from 2014 to 2016 by the X-band COSMO-SkyMed (CSK sensors. The long time gap (of about three years existing between the available C- and X-band datasets made the generation of unique displacement time-series more difficult. Nonetheless, this problem was successfully solved by benefiting from knowledge of time-dependent geotechnical models, which describe the temporal evolution of the expected deformation affecting Shanghai’s ocean-reclaimed platforms. The combined ENVISAT/CSK (vertical deformation time-series were analyzed to gain insight into the future evolution of displacement signals within the investigated area. As an outcome, we find that ocean-reclaimed lands in Shanghai experienced, between 2007 and 2016, average cumulative (vertical displacements extending down to 25 centimeters.

    The reuse of building materials becomes an important issue in sustainable engineering. As the technical requirements for civil engineering structures changes with time and the life time is limited, the need of building new objects meets the necessity of recycling of the existing ones. In the case of steel structures, the possibility of recycling is obvious, also in the case of wooden constructions, the possibility of “burning” solves the problem. The concrete waste is generated mainly as a result of the demolition and reconstruction of residential and industrial buildings. These types of waste are basically made from crushed rocks and cement minerals and contain non-hydrated cement particles in its composition. Concrete poses a lot of problems mainly for two reasons. It is difficult to crush, heavy and hard to transport and demanding in reuse. Different fractions (particle sizes) may be used for different purposes. Starting from very fine particles which can be used in concrete production, through regular 16-300 mm fractions used to form new fills and fill the mats, up to very irregular mixtures used to form stone columns by means of Impulse Compaction or in Dynamic Replacement. The presented study juxtaposes authors experience with crushed concrete used in civil engineering, mainly in geotechnical projects. Authors’ experiences comprise the application of crushed concrete in the new concrete production in Russia, changing pulverized bridge into the fill of mesh sacks, or mattresses used as an effective way to protect the shoreline and the New Orleans East land bridge after Katrina storm (forming a new shoreline better able to withstand wave actions), and finally the use of very irregular concrete fractions to form stone columns in week soils on the example of railway and road projects in Poland. Selected case studies are presented and summarized with regard to social, technical and economic issues including energy consumption needed for proposed technologies

    2006-12-01

    Planned and involuntary resettlement after natural disasters has been a major policy in post-disaster reconstruction in developing countries over the past few decades. Studies show that resettlement can result in significant adverse impacts on the resettled population. Conversely, a well-planned and managed resettlement process can produce positive long-term development outcomes. This article presents the results of a case study undertaken 11 years after the 1990 Manjil earthquake in Iran. During the reconstruction period, a policy of involuntary planned resettlement was pursued extensively. The socioeconomic changes that occurred as a consequence of this policy of involuntary resettlement are analysed. Data were collected via a questionnaire survey that involved a sample of 194 relocated households (grouped into a settlement that later became a town). The paper shows that relocated families face difficult socioeconomic challenges after relocation and regrouping. This is especially true with respect to employment, income, the empowerment of women and lifestyle issues.

    Amang or tin tailing is commonly found in the vicinity of disused mining area and responsible in downgrading the water quality, landscape and mechanical behaviour of soils. It was generated from extraction process of separating valuable metal from particular ore. This paper presents the geotechnical characteristics of amang-contaminated clay soil. The geotechnical properties of uncontaminated soils were studied in order to compare to that of amang contaminated soils. The base soil used in this study represents completely weathered horizon of meta sedimentary rock. Meanwhile, tin tailing sample was taken from the disused mine at Sungai Lembing, Pahang. The geotechnical characterisations of base soil and contaminated soils were determined based on consistency index, compaction behaviour, hydraulic conductivity and undrained shear strength (UU tests). Contaminated soil samples were prepared by adding 5, 10 and 20 % of tailing, based on dry weigh of the studied base soil. The results from the particle size distribution analysis showed that residual soil from meta sedimentary rock comprised 42.6 % clay, 32.2 % silt and 25.2 % sand whilst tailing was dominated by 98 % of sand fraction. XRD analysis indicated the presence of quartz, kaolinite and muscovite minerals in the studied soil. The specific gravity of soil used is 2.67 and the pH is 3.88. Tailing found to have higher specific gravity of 3.37. The consistency index of contaminated soils showed that liquid limit, wL and plastic limit, wP decreased with the increase in the percentage of tailing added to the soil samples. The value of maximum dry density, ρ dry max increased while optimum moisture content decreased due to the increase in tailing content in soil sample. The permeability of contaminated soil also increased with the increase in tailing contents ranged from 19.8 cm/ hr to 23.8 cm/ hr. The undrained shear strength, Cu, of contaminated soil decreased from 646 kPa (5 % of tailing) to 312 kPa (20 % of

    2014-12-01

    Spatial distribution of important geotechnical parameter named compression modulus Es contributes considerably to the understanding of the underlying geological processes and the adequate assessment of the Es mechanics effects for differential settlement of large continuous structure foundation. These analyses should be derived using an assimilating approach that combines in-situ static cone penetration test (CPT) with borehole experiments. To achieve such a task, the Es distribution of stratum of silty clay in region A of China Expo Center (Shanghai) is studied using the Bayesian-maximum entropy method. This method integrates rigorously and efficiently multi-precision of different geotechnical investigations and sources of uncertainty. Single CPT samplings were modeled as a rational probability density curve by maximum entropy theory. Spatial prior multivariate probability density function (PDF) and likelihood PDF of the CPT positions were built by borehole experiments and the potential value of the prediction point, then, preceding numerical integration on the CPT probability density curves, the posterior probability density curve of the prediction point would be calculated by the Bayesian reverse interpolation framework. The results were compared between Gaussian Sequential Stochastic Simulation and Bayesian methods. The differences were also discussed between single CPT samplings of normal distribution and simulated probability density curve based on maximum entropy theory. It is shown that the study of Es spatial distributions can be improved by properly incorporating CPT sampling variation into interpolation process, whereas more informative estimations are generated by considering CPT Uncertainty for the estimation points. Calculation illustrates the significance of stochastic Es characterization in a stratum, and identifies limitations associated with inadequate geostatistical interpolation techniques. This characterization results will provide a multi

    2017-10-01

    The use of Geographic Information Systems (GIS) has spread to several science areas, from oceanography to geotechnics. Its application in the urban mapping was intensified in the last century, which allowed a great development, due to the use of geographic database, new analysis tools and, more recently, free open source software. Geotechnical cartography struggle with a permanent and large environment re-organization in urban area, due to new building construction, trenching and the drilling of sampling wells and holes. This creates an extra important and largest volume of data at any pre-existence geological map. The main problem results on the fact that the natural environment is covered with buildings and communications system. The purpose of this work is to create a viable geographic information base for geotechnical mapping through a free GIS computer program and open source, with non-traditional cartographic sources, giving preference to open platforms. QGIS was used as software and “Google Maps”, “Bing Maps” and “OpenStreetMap” were applied as cartographic sources using the “OpenLayers plugin” module. Finally, we also pretend to identify and delimit the degree of granite’s change and fracturing areas using a “Streetview” platform. This model has cartographic input which are a geological map study area, open cartographic web archives and the use of “Streetview” platform. The output has several layouts, such as topography intersection (roads, borders, etc.), with geological map and the bordering area of Guarda Urban Zone. The use of this platform types decrease the collect data time and, sometimes, a careful observation of pictures that were taken during excavations may reveal important details for geological mapping in the study area.

    Global stroke epidemiology is changing rapidly. Although age-standardized rates of stroke mortality have decreased worldwide in the past 2 decades, the absolute numbers of people who have a stroke every year, and live with the consequences of stroke or die from their stroke, are increasing. Regular updates on the current level of stroke burden are important for advancing our knowledge on stroke epidemiology and facilitate organization and planning of evidence-based stroke care. This study aims to estimate incidence, prevalence, mortality, disability-adjusted life years (DALYs) and years lived with disability (YLDs) and their trends for ischemic stroke (IS) and hemorrhagic stroke (HS) for 188 countries from 1990 to 2013. Stroke incidence, prevalence, mortality, DALYs and YLDs were estimated using all available data on mortality and stroke incidence, prevalence and excess mortality. Statistical models and country-level covariate data were employed, and all rates were age-standardized to a global population. All estimates were produced with 95% uncertainty intervals (UIs). In 2013, there were globally almost 25.7 million stroke survivors (71% with IS), 6.5 million deaths from stroke (51% died from IS), 113 million DALYs due to stroke (58% due to IS) and 10.3 million new strokes (67% IS). Over the 1990-2013 period, there was a significant increase in the absolute number of DALYs due to IS, and of deaths from IS and HS, survivors and incident events for both IS and HS. The preponderance of the burden of stroke continued to reside in developing countries, comprising 75.2% of deaths from stroke and 81.0% of stroke-related DALYs. Globally, the proportional contribution of stroke-related DALYs and deaths due to stroke compared to all diseases increased from 1990 (3.54% (95% UI 3.11-4.00) and 9.66% (95% UI 8.47-10.70), respectively) to 2013 (4.62% (95% UI 4.01-5.30) and 11.75% (95% UI 10.45-13.31), respectively), but there was a diverging trend in developed and developing

    Full Text Available We have presented a comparison between the modeled NmF2 and hmF2, and NmF2 and hmF2, which were observed in the low-latitude ionosphere simultaneously by the Kokubunji, Yamagawa, Okinawa, Manila, Vanimo, and Darwin ionospheric sounders, by the middle and upper atmosphere (MU radar during 17-22 March 1990, and by the Arecibo radar for the time period of 20-22 March 1990. A comparison between the electron and ion temperatures measured by the MU and Arecibo radars and those produced by the model of the ionosphere and plasmasphere is presented. The empirical zonal electric field, the meridional neutral wind taken from the HWM90 wind model, and the NRLMSISE-00 neutral temperature and densities are corrected so that the model results agree reasonably with the ionospheric sounder observations, and the MU and Arecibo radar data. It is proved that the nighttime weakening of the equatorial zonal electric field (in comparison with that produced by the empirical model of Fejer and Scherliess (1997 or Scherliess and Fejer (1999, in combination with the corrected wind-induced plasma drift along magnetic field lines, provides the development of the nighttime enhancements in NmF2 observed over Manila during 17-22 March 1990. As a result, the new physical mechanism of the nighttime NmF2 enhancement formation close to the geomagnetic equator includes the nighttime weakening of the equatorial zonal electric field and equatorward nighttime plasma drift along magnetic field lines caused by neutral wind in the both geomagnetic hemispheres. It is found that the latitudinal positions of the crests depend on the E×B drift velocity and on the neutral wind velocity. The relative role of the main mechanisms of the equatorial anomaly suppression observed during geomagnetic storms is studied for the first time in terms of storm-time variations of the model crest-to-trough ratios of the equatorial anomaly. During most of the studied time period, a total contribution from

    A comparative study of the complex structure of the Bulgarian lands and the engineering geological criteria for site selection of national repositories for high level radwastes is made. A detailed description of the following geotechnical conditions of Bulgaria's territory is given: genetic, lithological and engineering-geological types of rocks; physico-mechanical parameters of the most widespread rocky and semi-rocky engineering geological types; fissuring of the rocks; rock massifs; geodynamic processes. The number of promising variants for repositories have been classified according to the structure of the rock massif and the engineering-geological properties of the layers which are promising for the purpose. The following sites are investigated: 1) sites in one-type homogeneous rock massifs of high strength and elasticity; 2) sites of various type massifs with a promising layer of rocks with medium strength and elasticity; 3) sites in various type massifs with a promising layer of plastic rocks of low strength. It is concluded that the complexity of the geotechnical and other conditions in the territory of Bulgaria would predetermine the deficiency of the list of the properties required for the selected sites. The building up of engineering defence will be needed to offset that deficiency and their problems will be resolved after the specific site have been chosen. Geotechnical elements should be likewise envisaged within the general pattern of the monitoring needed. The designing, installing and putting into operation of the monitoring systems should be accomplished as early as the stage of the detailed investigation of the site selected. 19 refs., 2 suppls.

Progress is reported in the chemical studies on the isolation and characterization of thymine glycols, isolation and characterization of glycols of 1-carbamylimidazolidone as products of cytosine, identification of the major hydroperoxy thymine (T 6 OOH), attempted synthesis of the nucleoside and nucleotide of T 6 OOH, and synthesis and characterization of 5-hydroperoxy-methyluracil. Progress is reported in the biological studies on the effects of T 6 OOH on nucleic acid components, on C--N glycosidic bonds, as a chemical mutagen, on the chromosomes of cells, and as a potential synergist of ionizing radiation. The photoproducts of uracil, cytosine, thymine, and thymidine that have been isolated and characterized are tabulated. (U.S.)

    Use of Horizontal Directional Drilling - HDD for large diameter (OD>20 inches) pipeline installation started in the second half of the seventies. Since then the method became the preferred alternative for situations in which it is necessary an underground pipeline but there are concerns about digging trenches. Crossings of roadways, water bodies and environmental sensitive areas are typical examples of its application. Technical and economic feasibility of HDD depends significantly on the properties of the materials that will be drilled. Lack of information about these materials can lead to several problems as: schedule delays, cost elevation, pipeline damage, unforeseen environmental impacts and even the failure of the entire operation. Ground investigation campaigns for HDD should define a consistent geological-geotechnical model, which must include determination of behaviour parameters for soil and rock masses that will be drilled. Thus it is proposed an investigation in tree stages: review of available geological-geotechnical information, site reconnaissance, and field survey. (author)

    A geotechnical investigation program has been completed for the Circulating Light Water Reactor - Tritium Extraction Facility (CLWR-TEF) at the Savannah River Site (SRS). The program consisted of reviewing previous geotechnical and geologic data and reports, performing subsurface field exploration, field and laboratory testing and geologic and engineering analyses. The purpose of this investigation was to characterize the subsurface conditions for the CLWR-TEF in terms of subsurface stratigraphy and engineering properties for design and to perform selected engineering analyses. The objectives of the evaluation were to establish site-specific geologic conditions, obtain representative engineering properties of the subsurface and potential fill materials, evaluate the lateral and vertical extent of any soft zones encountered, and perform engineering analyses for slope stability, bearing capacity and settlement, and liquefaction potential. In addition, provide general recommendations for construction and earthwork

  6. Organic matter and the geotechnical properties of submarine sediments

    Science.gov (United States)

    Keller, George H.

    1982-09-01

    Continental slope deposits off Peru and Oregon where coastal upwelling is a pronounced oceanographic process possess significant concentrations of organic carbon. Geotechnical properties are altered to varying degrees by the organic matter. Organic matter absorbs water and causes clay-size particles to aggregate forming an open fabric. This causes unusually high water contents and plasticity and exceptionally low wet bulk densities. Some of these deposits show notable increases in shear strength, sensitivity and degree of apparent overconsolidation. Owing to the unique geotechnical properties, sediment stability characteristics are considered to be poor in situations of excess pore pressures. Failure appears to take the form of a fluidized flow somewhat similar to the quick clays of Scandinavia.

    and friction angle varied from 18 to 56 kPa and from 1 o to 11 o , respectively. Similar to direct shear test results, as the waste degrades an increase in cohesion and slight decrease in friction angle was observed. Decreased friction angle and increased cohesion with increased degradation is believed to be due to the highly cohesive nature of the synthetic MSW. Variation of synthetic MSW properties from this study also suggests that significant changes in geotechnical properties of MSW can occur due to enhanced degradation induced by leachate recirculation.

    In keeping with the National Environmental Policy Act (1969), the Marine Mammal Protection Act (1972) and the Endangered Species Act (1973), the OCS Lands Act Amendments (1978) established a management policy that included studies in OCS lease sale areas to ascertain potential environmental impacts of oil and gas development on OCS marine coastal environments. The Minerals Management Service (MMS) is the agency responsible for these studies and for the leasing of submerged Federal lands. The report summarizes the 1990 investigations of the distribution, abundance, migration, behavior and habitat relationships of endangered whales in the Alaskan Chukchi and western Beaufort Seas (hereafter, study area); 1990 was the second of a three year (1989-91) study. The Bering Sea stock of bowhead whales (Balaena mysticetus) was the principal species studied, with incidental sightings of all other marine mammals routinely recorded. The 1990 season was compromised by circumstances that restricted the availability of the survey aircraft (Grumman Goose, model G21G) to the period 26 October - 7 November; opportunistic surveys were flown in the study area from 3-25 October. In 1990, there were 14 sightings of 19 bowheads from 9-29 October; 5 whales, including 2 calves, were seen north of the study area. One gray whale, 110 belukhas and 53 polar bears were also seen. Over nine survey seasons (1982-90), there were 240 sightings of 520 bowhead whales and 148 sightings of 398 gray whales

    Full Text Available The Crossrail project currently under construction in Central London has been described as “The Big Dig on Steroids”, obviously referencing the Central Artery/Tunnel project in Boston completed in 2007. To address the multiple demands for timely construction performance monitoring, Crossrail envisioned the underground construction information management system (UCIMS to monitor construction progress and structural health along the entire route, with a network of geotechnical instruments (i.e. slope inclinometers, extensometers, piezometers, etc. and tunnel boring machine (TBM position information. The UCIMS is a geospatially referenced relational database that was developed using an open source geographic information system (GIS that allowed all stakeholders near immediate feedback of construction performance. The purpose of this article is to provide a brief history of geotechnical and structural monitoring software, to describe the structure and operation of the UCIMS, and to demonstrate how the functionality afforded by this system provided the requisite feedback to the stakeholders. Examples will be given regarding how the data management and visualization concepts incorporated into the UCIMS advanced the geotechnical construction industry.

    The aims of this study were to estimate all-cause and cause-specific mortality and years of life lost, investigated by disability-adjusted life-years (DALYs), due to colorectal cancer attributable to physical inactivity in Brazil and in the states; to analyze the temporal trend of these estimates over 25 years (1990-2015) compared with global estimates and according to the socioeconomic status of states of Brazil. Databases from the Global Burden of Disease Study (GBD) for Brazil, Brazilian states and global information were used. It was estimated the total number and the age-standardized rates of deaths and DALYs for colorectal cancer attributable to physical inactivity in the years 1990 and 2015. We used the Socioeconomic Development Index (SDI). Physical inactivity was responsible for a substantial number of deaths (1990: 1,302; 2015: 119,351) and DALYs (1990: 31,121; 2015: 87,116) due to colorectal cancer in Brazil. From 1990 to 2015, the mortality and DALYs due to colorectal cancer attributable to physical inactivity increased in Brazil (0.6% and 0.6%, respectively) and decreased around the world (-0.8% and -1.1%, respectively). The Brazilian states with better socioeconomic indicators had higher rates of mortality and morbidity by colorectal cancer due to physical inactivity (pBrazil. Over 25 years, the Brazilian population showed more worrisome results than around the world. Actions to combat physical inactivity and greater cancer screening and treatment are urgent in the Brazilian states.

    Full Text Available Corporate Annual Reports (CARs are corporate communication tools which have been around for 75 years. They report company’s progress, profits and losses. At first, reports were provided in English, because they were published in an English speaking context. After a while, non-English speaking companies started to publish CARs in English to attract international investments. So far studies on CARs considered themes in text and images of CARs, subgenres of CARs, rhetorical construction, discourse and genre structure. During the last two decade; however, not many studies have been conducted on CARs from a language perspective. We aim to evaluate those studies and provide insight for further research. Findings of previous studies revealed that CARs consist of various sections functioning as sub-genres that have features of their own. Researchers so far have been interested in management forewords section as it is considered to be the most widely read section of CAR, which are supposed to gain the trust of readers. Other sub-genres studied include: operational and financial performance, corporate history and mission statements. As modern CARs are considered to be multimodal, images that appear in CARs have also been studied.

    During 1972, the total production was 31151 MWh which is 3.8% higher than planned. The reactor was used for irradiation and experiments according to the demand of 381 users, of which 340 from the Institute and 41 external users. This report contains detailed data about reactor power and experiments performed in 1972. Discrepancies from the action plan, meaning higher production was achieved due to special demands of the users. Total number of interruptions was lower than during all the previous years, and were caused mainly due to announced power cuts. There was only on scram shutdown during this year caused by a false signal of the reactor control instrumentation. There were no longer interruptions. One shorter interruption (shorter than 24 hours) caused by removal of a UO 2 capsule from the core, placed there for measuring heat transfer. Total personnel exposure dose was lower than during previous years. One accident caused contamination with gases and aerosols containing mainly shot-living isotopes. Decontamination od surfaces was less than during previous years. Practically there was no surface contamination that would demand action of the decontamination team, except for the regular decontamination after refueling. It was concluded that the successful operation in 1972 has a special significance having taking in account the financial crisis caused by the unresolved status of the reactor. It is emphasised, in the plan for the next year that there is an urgent need of making a long-term plan of rector application. It is indispensable to finish preparatory tasks for replacing the fuel with the highly enriched fuel elements by 1974, and building the core emergency cooling system [sr

    The study programme is divided into four topics. The first topic is a study on environmental doses, which was designed to identify levels of radioactivity, and characteristics and behavior of radiation sources in the ambient air, and to elucidate population dose estimates. The second topic concerning biological effects of radiation focusses on the elucidation for mechanism whereby radiation acts on the living body, for effects of low dose radiation using experimental animals, and for radiation effects on the human body using epidemiological approaches. The aim of the third topic is to study incorporation of alpha radiators, including transuranic elements, and tritium in the human body. The last topic is the safety evaluation, for which it is required to establish methods of evaluating human risk of environmental radiation and to prepare data base. An outline of these topics is given. (Namekawa, K.)

    How Irish 1985 Energy Demand Model (EDM) case study results have been optimized on the supply side, by means of the EFOM model and software, are described. The 1985 case study results are for low, likely, and high cases. The Low case represents a 1985 Irish economic profile for real GNP being 54% greater thand the GNP of 1974. The Likely case relates to 1985 real GNP being 70% greater than that of 1974, and the High to real GNP being 92% greater. The 1985 final energy results emerging from the case studies are tabulated, showing quantities of final energy required by each of the 13 sectors of the Irish EDM. In all three case studies, 5 of the 13 demand sectors take in aggregate more than 76% of the total energy; these five sectors, in decreasing size of demand, are: other household uses; other industries; private transport; cement; other services. The preparation for EFOM is described. The optimal final energy flows, with some comparisons with the non-optimal inital flows, are considered. The gross primary energy quantity and cost underlying the optimal final energy flows are examined in detail.

    The mortality and cancer incidence among offspring of atomic bomb survivors whose exposure dose was estimated in DS86 (Dose System 1986) were studied as one of means to evaluate the genetic influence of atomic bomb radiation. Big malformation incidence and mortality of subjects with the malformation were also studied. Death and its cause were traced from the city register and certificate of death of 67,586 offspring born in 1946-1984. Cancer was confirmed by certificate of death until 1957 and by cancer registration after 1958. Big malformation and the mortality were traced from clinical diagnostic records at birth or at necropsy, of 9-month examination after birth and of certificate of death. Comparisons were made in general and the offspring's age-related mortalities and in mortality or cancer incidence in relation to the radiation doses the parents had been exposed to. The comparisons showed no statistically significant relationships in those examined parameters. (K.H.)

    Full Text Available This work addresses the suitability of using X-band Synthetic Aperture Radar (SAR data for operational geotechnical monitoring of site scale slow moving landslides, affecting urban areas and infrastructures. The scale of these studies requires high resolution data. We propose a procedure for the practical use of SAR data in geotechnical landslides campaigns, that includes an appropriate dataset selection taking into account the scenario characteristics, a visibility analysis, and considerations when comparing advanced differential SAR interferometry (A-DInSAR results with other monitoring techniques. We have determined that Sentinel-2 satellite optical images are suited for performing high resolution land cover classifications, which results in the achievement of qualitative visibility maps. We also concluded that A-DInSAR is a very powerful and versatile tool for detailed scale landslide monitoring, although in combination with other instrumentation techniques.

    During the past year significant progress was made in carrying out theoretical investigations pursuant to the scientific mission of the Institute. These achievements may be approximately classified in terms of the following research categories (often with considerable overlap); tokamak MHD studies, turbulence theory and plasma transport, computational plasma physics, stability theory, mathematical physics, advanced ideas, and space plasma physics-related problems. An overview of this work is contained in this report. This paper contains a list of the numerous scientific papers published in technical journals by IFS scientists during the past year. Also, detailed summaries of IFS Reports written during FY 90 are given in abstract form in Appendix A of this report. It is worth noting that, in addition to the many research publications, two lengthy review articles were written during the past year at the IFS: one on nonlinear drift waves and transport in magnetized plasmas, and the other an introduction to bifurcation theory

    The geotechnical challenges for safe slope design in large scale surface mining operations are enormous. Sometimes one degree of slope inclination can significantly reduce the overburden to ore ratio and therefore dramatically improve the economics of the operation, while large scale slope failures may have a significant impact on human lives. Furthermore, adverse weather conditions, such as high precipitation rates, may unfavorably affect the already delicate balance between operations and safety. Geotechnical, weather and production parameters should be systematically monitored and evaluated in order to safely operate such pits. Appropriate data management, processing and storage are critical to ensure timely and informed decisions. This paper presents an integrated data management system which was developed over a number of years as well as the advantages through a specific application. The presented case study illustrates how the high production slopes of a mine that exceed depths of 100-120 m were successfully mined with an average displacement rate of 10- 20 mm/day, approaching an almost slow to moderate landslide velocity. Monitoring data of the past four years are included in the database and can be analyzed to produce valuable results. Time-series data correlations of movements, precipitation records, etc. are evaluated and presented in this case study. The results can be used to successfully manage mine operations and ensure the safety of the mine and the workforce.

    Magnetic and geotechnical methods were used for shallow subsurface soil characterization at Sungai Batu, Kedah, (Malaysia). Ground magnetic data were collected along a survey line of length 160 m long at 2 m constant station spacing, while soil drilling using hand auger was conducted at 21 m on the survey line using 0.2 m sampling interval drilled to a depth of 5 m. Result from the processed magnetic profile data shows distribution of magnetic residuals in the range of -4.55 to 1.61 nT, with magnetic low (-4.55 nT to -0.058 nT) and were identified at distances 4 m, 10 to 16 m, 20 to 26 m, 58 m, 82 m, 104 to 106 m, 118 m, and 124 to 140 m. The magnetic lows are attributes of sediments. The result from the soil drilling shows sticky samples with variable sizes, greyish to brownish / reddish in colour, and some of the samples show the presence of shiny and black spots. The characteristics of the samples suggest the soil as a by-product of completely weathered rock; weak with high water content and classified as Grade V soil. The study concludes; integration of geophysical and geotechnical methods aided in characterizing the subsurface soil at Sungai Batu. The result was correlated with previous studies and confirms the importance of integrated approach in minimising ambiguity in interpretation.

    Due to the Philippines's island-arc setting, andesitic tuff and volcanic ash constitute two-thirds of the country's agricultural land. In situ weathering of these volcanic sediments produces volcanic soils. Metro Manila volcanic soils were studied to determine their suitability for landfill soil liner. The soils were analyzed using XRD and XRF, and were tested for geotechnical properties. The results show the presence of the smectite group, a swelling variety of clay. The smectite-type clays are weathering products of volcanic glasses which are dominant components of the parental rocks. The high amounts of Al2O3 indicate an Al-rich type of soil. The clay species is either di- or tri-octahedral type, which points to montmorillonite as the main clay species. Swelling clay lowers the permeability of soils and reduces the infiltration and lateral movement of leachates in the ground. Also, geotechnical tests revealed moderate to high plasticity indices and low hydraulic conductivity values. The study shows that the physicochemical characteristics of volcanic soils meet the criteria for a soil liner for future sanitary landfill projects as mandated by RA 9003, a recently ratified solid waste management act of the Philippines. Being widespread, volcanic soils can be viewed as an important resource of the country.

    The Institute for Nuclear Study (INS) was established in 1955 as an inter-university center for nuclear and particle physics research in the post-war era. During its long history, it has played important roles in promoting research activities in this field. At present, two accelerator facilities (the SF cyclotron and the 1.3 GeV electron synchrotron) are open for use by all researchers throughout the country. These accelerators are actively being used for nuclear and particle physics as well as interdisciplinary research with particle beams and various forms of radiation. In addition, accelerator-development programs are in progress for the TARN II stretcher/cooler ring and heavy-ion linacs. During these years the Institute has been making intense efforts to materialize a proposal to construct the Japanese Hadron Project for exploring a variety of frontier fields in nuclear and particle physics, in condensed-matter physics, and in atomic physics. Various working groups have been organized to finalize the design of this project. (J.P.N.)

    During the three year period of this grant, a major initiative was started to develop theoretical methods to treat complex open-shell atoms in a manner permitting a simple interpretation of the dynamics. This project has been far more successful than originally hoped, with accurate ground state photoionization cross sections calculated for nine different open-shell atoms in the periodic table. This work culminated in our first application to multichannel autoionizing spectra of a transition metal atom, scandium. These methods were also extended and adapted to permit a description of nonresonant two-photon processes at the perturbative level, and some nonperturbative multiphoton processes. The angular distribution of photoelectrons ejected in resonant multiphoton ionization of magnesium was also successfully calculated. We made headway toward understanding aspects of the diamagnetic quasi-Landau problem, specifically interpreting the observed simplicity of the spectrum when plotted simultaneously versus energy and field. High two-electron excitations of H - and Li - were treated using R-matrix methods, combined with a time delay analysis to quantitatively test various propensity rules proposed in the literature. These calculations also gave the first accurate description of H - experiments at Los Alamos, up to the n = 6 threshold. A new set of computer programs were developed to handle double-Rydberg ''planetary'' states of barium and strontium, incorporating long range multipole interactions explicitly. Finally, we studied triply-excited states of H -- in an attempt to clarify the question of whether such resonances exist. Each of these projects is described in greater detail below

    Did the demise of the Soviet Union in 1991 influence the scientific performance of the researchers in Eastern European countries? Did this historical event affect international collaboration by researchers from the Eastern European countries with those of Western countries? Did it also change international collaboration among researchers from the Eastern European countries? Trying to answer these questions, this study aims to shed light on international collaboration by researchers from the Eastern European countries (Russia, Ukraine, Belarus, Moldova, Bulgaria, the Czech Republic, Hungary, Poland, Romania, and Slovakia). The number of publications and normalized citation impact values are compared for these countries based on InCites (Thomson Reuters), from 1981 up to 2011. The international collaboration by researchers affiliated to institutions in Eastern European countries at the time points of 1990, 2000 and 2011 was studied with the help of Pajek and VOSviewer software, based on data from the Science Citation Index (Thomson Reuters). Our results show that the breakdown of the communist regime did not lead, on average, to a huge improvement in the publication performance of the Eastern European countries and that the increase in international co-authorship relations by the researchers affiliated to institutions in these countries was smaller than expected. Most of the Eastern European countries are still subject to changes and are still awaiting their boost in scientific development.

    This report describes the results of a laboratory study on the geotechnical properties of the Tertiary Boom clay. Tests were performed on 'undisturbed' samples of clay taken from a location 247 m below surface at the SCK/CEN experimental site at Mol in Belgium. In geotechnical terms, the Boom clay (at depth) may be described as a hard, high-plasticity, overconsolidated clay. Test methods have included (a) the one-dimensional consolidation test with consolidation stresses up to 32 MPa, (b) the one dimensional swelling pressure test, (c) the isotropically-consolidated, undrained (CIU) triaxial test with pore pressure measurement, and (d) the unconsolidated undrained (UU) triaxial test. All triaxial tests were load-controlled. Limited test results are presented on pore pressure responses during heating under undrained conditions and on the effect of elevated temperature (80 O C) on deformability and strength. It is found that significantly large excess pore pressures (circa 1 MPa under in situ stress conditions) may be developed during heating from ambient laboratory temperature to 80 O C. The effect is due, at least in part, to the expansion of the pore fluid

    Electrical resistivity survey and the geotechnical SPT blow counts (N-value) were carried out simultaneously on the tropically weathered sedimentary rock mass for an excavation project at Nusajaya, Johor, Malaysia. This study aims to determine subsurface profile by using 2D-resistivity methods and correlate with N-value derived from boring works. Four boreholes were investigated in five survey lines that revealed the site is underlain by moderately to completely weathered sandstone, clay, silt and shale. Data analysis from 2D-resistivity image shows that zones with high resistivity value generally have high N-value, and vice versa. Five zones have inversed the proportional relation between N-value and resistivity Ωm value due to different types of soil lithology. It indicates that 2D-resistivity is significance to detect bodies of anomalous materials or estimating the depth of bedrock. As a conclusion, the integration of geophysical and geotechnical analysis provides a promise approach to understand some relationship concerning the subsurface subsurface ground through the combination of 2D-resistivity and N-value.

    A thesis is an important part of nursing graduate students' education, which is also their first systematic and scientific attempt to learn the ABCs of research. Articles derived from theses are important for the dissemination of science and the improvement of nursing as a field. Therefore, it is the goal of the present research is to analyze the different aspects of nursing MSc theses and the number of published articles derived from them. This was a descriptive research carried out on 145 nursing MSc theses defended in Razi Faculty of Nursing and Midwifery in Kerman between 1990 and 2010. All of the extracted data were put into an Excel file (2007 version) followed by a data analysis. The results of this study were then presented via the use of descriptive statistics and figures. The research findings showed that most of the theses used a descriptive or analytical-descriptive method, and 42% of them had patients as their participants. They were usually delivered on the subject of health care, and only 58 articles were extracted from the whole 145 theses. The process of writing nursing MSc theses and thesis research articles is improving gradually. However, there is a growing need for empirical and semi-empirical research to bridge the gap between theory and practice, which is also a major concern among nurses.

    Full Text Available Experiences of different countries with efficient tax systems have shown that the high share of tax resources than non-tax sources could prevent many unpleasant economical events. In other words, an efficient tax system could ensure economic system against many different risks. Tax is also a primary source for developing economy used by government. In this study, we investigate the relationship between economic growth and tax among D8 countries using panel data from 1990 to 2009. The results indicate growth domestic product is the most important factor and these governments could collect more tax as the economic figures improve. The results of our survey show that an increase of one percent on GDP will increase taxable income for about 0.0014119 percent. The tourism has more impact since an increase of one unit in tourism's income; taxable income will increase for about 10.26257 units. One the contrary to other variables, unemployment has a negative impact on taxable income.

    The variations of the geologic characteristics of the subsurface materials can have direct impact in the pipeline projects. The elaboration of a geotechnical zoning have intention to reduce, among others, these uncertainties and consequently to minimize costs of implantation and maintenance. The present paper intends to present the experiences obtained through the elaboration of a geotechnical zoning as well as a panorama of the tools and currently available methods. The pipes studied, object of this work, are situated in Rio de Janeiro state, between Cabiunas and Duque de Caxias cities, with an extension upper 200 km, crossing lands with very different characteristics, from fluvial marine lowlands, constituted of quaternary sediments to mountain regions, formed of metamorphic and igneous rocks. The database used in an GIS environment include satellite images, three-dimensional models of the land, digital air photographs, laser airborne for generation of digital elevation models DEM, geologic, geomorphologic, pedological maps and land surveys. The integration of these different levels of information, also with the digital 3D photo interpretation with the geomorphologic contacts, beyond maps of declivity generated from xyz data, resulted in geotechnical maps, scale 1:10.000, with the order of 750 meters borders for each side of the pipeline direction.

    During the selection of a site for Nuclear Power Plant (NPP) and Radioactive Waste Plant (RWP), geotechnical investigations play a significant role in deciding merits and demerits of the sites. Any accidents in these units can play havoc on mankind and may leave bitter imprints on generations to come. Hence proper care has to be taken at the early stage for selecting the sites. Site selection procedure is a complicated one, because it involves experts from various disciplines like geology, geophysics, civil, mechanical electrical engineering, health-physics and other fields

    Freeman, T.J.; Schuttenhelm, R.T.E.

    1990-01-01

    A site investigation in deep water often relies solely on laboratory tests to evaluate the geotechnical properties of the sediments. This imposes two fundamental limitations on the investigation: The maximum depth to which the properties can be profiled and the uncertainty of sample disturbance and de-pressurization effects on the measured data. This paper uses results from investigations performed in a water depth of 5.4 km at an abyssal plain site, Great Meteor East (GME), to illustrate how ambiguities can arise in laboratory measurements of strength, and discusses how a simple in-situ test, the expendable penetrator, can be used to corroborate the laboratory data

Therefore, the geotechnical aspects evaluation of NPP siting in particular must be implemented properly and accurately. The successful of the design and construction of the building system is influenced by geotechnical conditions in the vicinity of NPP will be built. To be able to perform geotechnical analysis is good and true; it's required data of surface/underground completely. These data can be obtained directly not only from the geotechnical field investigations, but also can be obtained from the laboratory tests results. To ensure that geotechnical investigations are conducted effectively and efficiently, produce accurate data, as well as meeting the requirements of safety, health, safety, environmental, quality and economic, then the Quality Assurance Program (QAP) should be established and implemented. Supervision of the QAP implementation is required to ensure the work is done according to QAP that have been established and applicable requirement. (author)

    Diarrheal diseases (DD) are leading causes of disease burden, death, and disability, especially in children in low-income settings. DD can also impact a child's potential livelihood through stunted physical growth, cognitive impairment, and other sequelae. As part of the Global Burden of Disease Study, we estimated DD burden, and the burden attributable to specific risk factors and particular etiologies, in the Eastern Mediterranean Region (EMR) between 1990 and 2013. For both sexes and all ages, we calculated disability-adjusted life years (DALYs), which are the sum of years of life lost and years lived with disability. We estimate that over 125,000 deaths (3.6% of total deaths) were due to DD in the EMR in 2013, with a greater burden of DD in low- and middle-income countries. Diarrhea deaths per 100,000 children under 5 years of age ranged from one (95% uncertainty interval [UI] = 0–1) in Bahrain and Oman to 471 (95% UI = 245–763) in Somalia. The pattern for diarrhea DALYs among those under 5 years of age closely followed that for diarrheal deaths. DALYs per 100,000 ranged from 739 (95% UI = 520–989) in Syria to 40,869 (95% UI = 21,540–65,823) in Somalia. Our results highlighted a highly inequitable burden of DD in EMR, mainly driven by the lack of access to proper resources such as water and sanitation. Our findings will guide preventive and treatment interventions which are based on evidence and which follow the ultimate goal of reducing the DD burden. PMID:27928080

  3. Mortality and years of life lost by colorectal cancer attributable to physical inactivity in Brazil (1990–2015): Findings from the Global Burden of Disease Study

    2018-01-01

    Introduction The aims of this study were to estimate all-cause and cause-specific mortality and years of life lost, investigated by disability-adjusted life-years (DALYs), due to colorectal cancer attributable to physical inactivity in Brazil and in the states; to analyze the temporal trend of these estimates over 25 years (1990–2015) compared with global estimates and according to the socioeconomic status of states of Brazil. Methods Databases from the Global Burden of Disease Study (GBD) for Brazil, Brazilian states and global information were used. It was estimated the total number and the age-standardized rates of deaths and DALYs for colorectal cancer attributable to physical inactivity in the years 1990 and 2015. We used the Socioeconomic Development Index (SDI). Results Physical inactivity was responsible for a substantial number of deaths (1990: 1,302; 2015: 119,351) and DALYs (1990: 31,121; 2015: 87,116) due to colorectal cancer in Brazil. From 1990 to 2015, the mortality and DALYs due to colorectal cancer attributable to physical inactivity increased in Brazil (0.6% and 0.6%, respectively) and decreased around the world (-0.8% and -1.1%, respectively). The Brazilian states with better socioeconomic indicators had higher rates of mortality and morbidity by colorectal cancer due to physical inactivity (pBrazil. Conclusions Over 25 years, the Brazilian population showed more worrisome results than around the world. Actions to combat physical inactivity and greater cancer screening and treatment are urgent in the Brazilian states. PMID:29390002

    Two holes were hand augered and sampled in ash deposits near Hilo, Hawaii. Color, water content and sensitivity of the ash were measured in the field. The ash alternated between reddish brown and dark reddish brown in color and had water contents as high as 392%. A downhole vane shear device measured sensitivities as high as 6.9. A series of laboratory tests including grain size distribution, Atterberg limits, X-ray diffraction analysis, total carbon determination, vane shear, direct shear and triaxial tests were performed to determine the composition and geotechnical properties of the ash. The ash is very fine grained, highly plastic and composed mostly of gibbsite and amorphous material presumably allophane. The ash has a high angle of internal friction ranging from 40-43? and is classified as medium to very sensitive. A series of different ash layers was distinguished on the basis of plasticity and other geotechnical properties. Sensitivity may be due to a metastable fabric, cementation, leaching, high organic content, and thixotropy. The sensitivity of the volcanic ash deposits near Hilo is consistent with documented slope instability during earthquakes in Hawaii. The high angles of internal friction and cementation permit very steep slopes under static conditions. However, because of high sensitivity of the ash, these slopes are particularly susceptible to seismically-induced landsliding.

    The building housing the zero power split table machine for reactor physics studies was officially opened by the Prime Minister, the Right Honourable William McMahon, on 19th June, 1972. Preparation of the Safety Document for the machine continued and the collection began of components for the first reactor assembly which will use fuel already available. An order was placed with CERCA (Compagnie pour Vitude et la R6alisation de Combustibles Atomiques) for delivery of 15 kg 235 U during the first quarter of 1973. Major effort continued to be devoted to the safety analysis of the Commission's other reactors. MOATA was prepared for 100 kW operation, with increased interest in its use for neutron beam work in physics and metallurgy fields. A convenient pneumatic transfer unit is now operational for analysis of uranium ores by delayed neutron analysis and levels down to 0.001 per cent have been detected with reasonable accuracy. A major review of nuclear reactions in the analysis of materials was prepared. Installation commenced on a system of switching and focussing magnets to provide protons and hence neutrons at a point 4 m above the floor and equidistant from the walls and roof of the building. This should reduce scattered neutron return problems with the neutron capture gamma ray studies and the fast neutron transport experiment in thorium metal. Analysis continued at a more intense level on the neutron capture cross section measurements from Oak Ridge National Laboratory. This analysis forms an important aspect of our work as long as our major equipment is unable to compete with the excellent Oak Ridge National Laboratory Electron Linear Accelerator. Collaboration takes the form of material assistance in the analysis of the abundance of information supplied by this facility to which we hope to provide a few confirmatory checkpoints. The advent of the zero power split table machine provided the impetus for a critical examination of the adequacy of our data library

    Contamination of soil due to an oil spill influences its subsequent engineering behavior. An investigation was conducted to study the effect of crude oil contamination on compaction characteristics, shear strength, one-dimensional compression, and coefficient of permeability. Water permeability was also determined by using commercial grade motor oils as contaminants. The test results indicate that the compaction characteristics are influenced by oil contamination. The angle of internal friction of sand (based on total stress condition) decreases due to presence of oil within the pore spaces in sand. One dimensional compression characteristics of sand are significantly influenced by oil contamination resulting in a decrease in the value of constrained modulus with increase in the degree of oil contamination compared to the case of dry sand. Water permeability was observed to be a function of the initial viscosity and the degree of saturation due to the contaminating oil

    Full Text Available Solid waste landfills are important engineering structures for protection of wastes, decrease of environmental pollution, and especially prevention of soil and water pollution. Solid wastes should conveniently be maintained in landfill areas to control environmental pollution caused by waste disposals. Until the middle of this century clay liners were used for maintenance of waste disposal, but it was observed that these liner systems were insufficient. Today thinner and less permeable liner systems are constructed by using synthetic materials. In this study, by evaluating the waste landfills, site assessment of landfills and construction of natural and synthetic liner systems were summarized respectively, and especially the design properties of these systems were examined intensively. Also, leachate collection and removal facilities, landfill gas collection unites, and final cover unites were evaluated in a detailed way.

    In Sweden 20 000 cases of assault against women are reported to the police every year. All data on the perpetrators of spousal homicide in Sweden between 1990 and 1999 were investigated (n = 164). A control group of all other perpetrators of homicide in Sweden during the same period, i.e. cases of homicide not committed in the context of spouse violence (n = 690) was used. All verdicts, as well as all material in the police investigations, including interviews with all of the police investigators, were analysed. Copies of police examinations of the suspects, and forensic reports from the autopsies, were also examined. Data on all registered criminality were collected from the National Police Register, and in cases where the perpetrators had been subject to forensic psychiatric examinations, those reports were obtained from the Swedish National Board of Forensic Medicine. In addition, the Psychopathy Checklist: Screening Version scores were rated from the forensic psychiatric examinations. There was a four times higher suicide rate among the spousal homicide perpetrators (24%, n = 40) compared with the perpetrators in the control-group (6%, n = 39, chi-squared = 55,42 df = 1, p suicidal ideation must be considered as an important risk factor for spousal homicide. In 79% of the cases the spousal homicide perpetrators were subject to forensic psychiatric examinations. All except 5% were diagnosed with at least one psychiatric diagnosis, and 34% were sentenced to forensic psychiatric treatment. If it is assumed that the psychiatric morbidity was high in the 24% of the perpetrators who committed suicide, then 80% of all perpetrators of spouse homicide during the study period can be characterized as mentally disordered. 'Psychopathic' perpetrators, who generally are over-represented in most violent criminality, were comparatively uncommon. Only seven (4%) in the study group met the diagnostic criteria for psychopathy as measured with the PCL:SV. The group of spouse

    Full Text Available Ariebreen is a small (0.37 km2-valley glacier located in southern Spitsbergen. Our ground-penetrating radar surveys of the glacier show that it is less than 30 m thick on average, with a maximum thickness of 82 m, and it appears to be entirely cold. By analysing digital terrain models of the ice surface from different dates, we determine the area and volume changes during two periods, 1936–1990 and 1990–2007. The total ice volume of the glacier has decreased by 73% during the entire period 1936–2007, which is equivalent to a mean mass balance rate of −0.61±0.17 m y−1 w.eq. The glacier thinning rate has increased markedly between the first and second periods, from −0.50±0.22 to −0.95±0.17 m y−1 w.eq.

    1978-10-01

    The Department of Energy is proposing to demonstrate the acceptability of geologic disposal of radioactive waste by locating a Waste Isolation Pilot Plant (WIPP) in the salt beds 26 miles east of Carlsbad, New Mexico. The WIPP will serve as a permanent repository for defense generated transuranic contaminated waste and will also be used as a facility in which experiments and demonstrations with all radioactive waste types can be conducted. The present area being proposed for the WIPP is the second such location in the Delaware Basin for which new site data have been developed; the first site proved geologically unacceptable. Ecologic and socioeconomic aspects have been investigated and extensive geophysical, geological and hydrologic studies have been conducted to allow an evaluation of site acceptability. Geotechnical aspects of site characterization are examined. These studies are now sufficiently complete that the site can be recommended for further development of the WIPP

    Full Text Available Abstract Background Relative deprivation has previously been discussed as a possible mechanism underlying the income-health relation. The idea is that income matters to the individual’s health, over and above the increased command over resources, as the basis of social comparisons between a person and his or her reference group. The following study aimed to analyze the role of individual-level relative deprivation for all-cause mortality in the Swedish population. The Swedish context, characterized by relatively small income inequalities and promoting values as egalitarianism and equality, together with a large data material provide unique possibilities for analyzing the hypothesized mechanism. Methods The data used are prospective longitudinal data from the Swedish population and based on a linkage of registers. Restricting selection to individuals 25–64 years, alive January 1st 1990, gave 4.7 million individuals, for whom a mortality follow-up was done over a 16-year period. The individual level relative deprivation was measured using the Yitzhaki index, calculating the accumulated shortfall between the individual’s income and the income of all other’s in the person’s reference group. All-cause mortality was used as the outcome measure. Results Relative deprivation, generated through social comparisons, is one possible mechanism within the income and health relation. The present study analyzed different types of objectively defined reference groups, all based on the idea that people compare themselves to similar others. Results show relative deprivation, when measured by the Yitzhaki index, to be significantly associated with mortality. Also, we found a stronger effect among men than among women. Analyzing the association within different income strata, the effect was shown to be weak among the poorest. Revealing the importance of relative deprivation for premature mortality, over and above the effect of absolute income, these

  17. Engineering geologic and geotechnical analysis of paleoseismic shaking using liquefaction effects: Field examples

    Green, R.A.; Obermeier, S.F.; Olson, S.M.

    2005-01-01

    The greatest impediments to the widespread acceptance of back-calculated ground motion characteristics from paleoliquefaction studies typically stem from three uncertainties: (1) the significance of changes in the geotechnical properties of post-liquefied sediments (e.g., "aging" and density changes), (2) the selection of appropriate geotechnical soil indices from individual paleoliquefaction sites, and (3) the methodology for integration of back-calculated results of strength of shaking from individual paleoliquefaction sites into a regional assessment of paleoseismic strength of shaking. Presented herein are two case studies that illustrate the methods outlined by Olson et al. [Engineering Geology, this issue] for addressing these uncertainties. The first case study is for a site near Memphis, Tennessee, wherein cone penetration test data from side-by-side locations, one of liquefaction and the other of no liquefaction, are used to readily discern that the influence of post-liquefaction "aging" and density changes on the measured in situ soil indices is minimal. In the second case study, 12 sites that are at scattered locations in the Wabash Valley and that exhibit paleoliquefaction features are analyzed. The features are first provisionally attributed to the Vincennes Earthquake, which occurred around 6100 years BP, and are used to illustrate our proposed approach for selecting representative soil indices of the liquefied sediments. These indices are used in back-calculating the strength of shaking at the individual sites, the results from which are then incorporated into a regional assessment of the moment magnitude, M, of the Vincennes Earthquake. The regional assessment validated the provisional assumption that the paleoliquefaction features at the scattered sites were induced by the Vincennes Earthquake, in the main, which was determined to have M ??? 7.5. The uncertainties and assumptions used in the assessment are discussed in detail. ?? 2004 Elsevier B

    Mental and substance use disorders (MD) are highly prevalent and have a high social and economic cost. To describe the burden of disease attributable to mental and substance use disorders in Brazil and Federated Units in 1990 and 2015. Descriptive study of the burden of mental and substance use disorders, using age-standardized estimates from the Global Burden of Disease Study 2015: years of life lost due to premature mortality (YLL); years lived with disability (YLD); and disability-adjusted life year (DALY=YLL+YLD). In Brazil, despite low mortality rates, there has been a high burden for mental and substance use disorders since 1990, with high YLD. In 2015, these disorders accounted for 9.5% of all DALY, ranking in the third and first position in DALY and YLD, respectively, with an emphasis on depressive and anxiety disorders. Drug use disorders had their highest increase in DALY rates between 1990 and 2015 (37.1%). The highest proportion of DALY occurred in adulthood and in females. There were no substantial differences in burden of mental and substance use disorders among Federated Units. Despite a low mortality rate, mental and substance use disorders are highly disabling, which indicates the need for preventive and protective actions, especially in primary health care. The generalization of estimates in all the Federated Units obtained from studies conducted mostly in the south and southeast regions probably does not reflect the reality of Brazil, indicating the need for studies in all regions of the country.

    To report on long-term trends in hospital admission rates for anorexia nervosa using two English datasets. We used data on hospital day-case and inpatient care across five decades in the Oxford Record Linkage Study (ORLS), and similar data for all England from 1990. We analysed rates of admission for anorexia nervosa in people aged 10-44 years, using hospital episodes (counting every admission) and first-recorded admissions (counting only the first record for each person). Former Oxford NHS Region; and England. None; anonymous statistical records were used. In the longstanding ORLS, the age-standardised first-recorded admission rate for women was 2.7 (95% confidence interval 1.6-3.8) per 100,000 female population aged 10-44 years in 1968-1971; 2.7 (2.1-3.3) in 1992-1996; and 6.3 (5.5-7.2) in 2007-2011. Male rates were zero in the 1960s; 0.07 (0.0-0.1) per 100,000 men in 1992-1996; and 0.4 (0.2-0.6) in 2007-2011. In England, female rates increased from 4.2 (4.0-4.4) in 1998-2001 to 6.9 (6.7-7.1) in 2007-2011; and the corresponding male rates were 0.2 (0.1-0.3) and 0.5 (0.4-0.6). Episode-based admission rates rose more than person-based rates. The highest rates by far were in girls and women aged 15-19 years. In recent years, anorexia nervosa has become a greater burden on secondary care: not only have admission rates increased but so too have multiple admissions per person with anorexia nervosa. The increase in admission rates might reflect an increase in prevalence rates of anorexia nervosa in the general population, but other explanations, including lower clinical thresholds for admission, are possible and are discussed. © The Royal Society of Medicine.

    The Mildred Lake Settling Basin (MLSB) is an oil sand tailings pond with a water area of about 11 square km and a maximum depth of mature fine tailings (MFT) of about 50 m, rendering it Syncrude's largest disposal site for tailings. Syncrude began storing the MFT in 1978 but in recent years there has been a sharp increase in the consolidation of the fine tailings, creating pumping challenges in the transfer of tailings from the MLSB for the creation of composite tailings. This paper presents preliminary results of field and laboratory study which have been launched to better manage the rapid densification of fine tailings. The study involves sampling, field vane tests, cone penetration tests, steel plate penetration tests and earth pressure measurements. Methane producing microorganisms have become very active in the part of the pond that is experiencing rapid densification. The objective of the study was to determine the inventory and distribution of high strength MFT in current storage ponds and to assess whether geotechnical properties are enough to support direct loading with solids such as sand, clay or coke. The cause of the phenomena was also examined along with ways to possibly enhance MFT development through microbial, physical or chemical treatments. Results show that the accumulation of methane gas may have reached a critical state in some parts of the pond. The densification phenomenon at the southern pond is more significant compared to the northern pond. Earth pressure measurements indicate that the earth pressure cell has good sensitivity and that the coefficient of earth pressure at rest is approximately one. Good agreement was reached between different testing methods used to determine geotechnical properties of MFT. 5 refs., 4 tabs., 14 figs.

The results obtained show that the increase in RHA content increased the OMC but decreased the MDD. It was also discovered that increase in RHA content, reduced plasticity and increased volume stability as well as the strength of the soil. 10% RHA content was also observed to be the optimum content.

    This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying reaction. The research contributes to developing a coal liquefaction technology as one of the methods for manufacturing clean energy and chemical raw materials from coal. In the fundamental study on the liquefaction, primarily liquefied heavy constituents in different types of coals were divided into such constituents as HI, TI, and THFI to discuss the performance and coking behavior of each constituent as solvent. Furthermore, effects of hydrogenation treatment were also elucidated. Decomposing reaction was performed on different heavy products to discuss effects of the reaction conditions. In the liquefying reaction using petroleum-based heavy oil as solvent, different shale oils were used in experiments for comparison with the case of using tar sand bitumen. In the study of reforming the product, comparison was carried out on reactions in hydrogenation treatment and contact decomposition of medium to heavy fractions of liquefied oil. A separation experiment was made on hetero compounds by means of solvent extraction and pressure crystallization of liquefied oil naphtha and light oil fraction. Effects of additive were investigated in an engine test on the stabilized and balanced light oil fraction. Discussions were given on high level utilization of heat treated oil recovered from residues in liquefaction distillation. (NEDO)

    To report mortality and disability due to rheumatoid arthritis (RA) in the Nordic region (Denmark, Finland, Greenland, Iceland, Norway, and Sweden) using data from the Global Burden of Disease Study (GBD) 2015. Using the results of GBD 2015, we present rates and trends in prevalence, mortality, years of life lost, years lived with disability (YLD), and disability-adjusted life-years (DALYs) of RA in the Nordic region during 1990-2015. In 2015, the age-standardized prevalence of RA was higher in the Nordic region than the global level (0.44%, 95% uncertainty interval 0.40-0.48%, vs 0.35%, 0.32-0.38%). For women (men), DALYs increased by 2.4% (12.9%), from 29 263 (10 909) in 1990 to 29 966 (12 311) in 2015. The burden of RA as a proportion of total DALYs in women (men) increased from 0.90% (0.29%) in 1990 to 0.94% (0.36%) in 2015. Age-standardized DALY rates declined in all countries except Denmark and Greenland between 1990 and 2015. Of 315 conditions studied, RA was ranked as the 16th (37th) leading cause of YLD in women (men) in the region. Of 195 countries studied, Greenland, Finland, Denmark, Norway, Sweden, and Iceland had the 7th, 11th, 28th, 38th, 48th, and 78th highest age-standardized YLD rates for RA, respectively. The prevalence of RA in the Nordic region is higher than the global average. Current trends in population growth and ageing suggest a potential increase in RA burden in the coming decades in the region that should be considered in healthcare resources allocation.

  7. The social costs to the US of monopolization of the world oil market, 1972--1991

    The partial monopolization of the world oil market by the OPEC cartel has produced significant economic costs to the economies of the world. This paper reports estimates of the costs of monopolization of oil to the US over the period 1972--1991. Two fundamental assumptions of the analysis are, (1) that OPEC has acted as a monopoly, albeit with limited control, knowledge, and ability to act and, (2) that the US and other consuming nations could, through collective (social) action affect the cartel's ability to act as a monopoly. We measure total costs by comparing actual costs for the 1972--1991 period to a hypothetical ''more competitive'' world oil market scenario. By measuring past costs we avoid the enormous uncertainties about the future course of the world oil market and leave to the reader's judgment the issue of how much the future will be like the past. We note that total cost numbers cannot be used to determine the value of reducing US oil use by one barrel. They are useful for describing the overall size of the petroleum problem and are one important factor in deciding how much effort should be devoted to solving it. Monopoly pricing of oil transfers wealth from US oil consumers to foreign oil producers and, by increasing theeconomic scarcity of oil, reduces the economy's potential to produce. The actions of the OPEC cartel have also produced oil price shocks, both upward and downward, that generate additional costs because of the economy's inherent inability to adjust quickly to a large change in energy prices. Estimated total costs to the United States from these three sources for the 1972--1991 period are put at $4.1 trillion in 1990$($1.2 T wealth transfer, $0.8 T macroeconomic adjustment costs, $2.1 T potential GNP losses). The cost of the US's primary oil supply contingency program is small ($10 B) by comparison

  8. Reforecasting the 1972-73 ENSO Event and the Monsoon Drought Over India

    This paper presents the results of reforcasting the 1972-73 ENSO event and the Indian summer monsoon drought using the National Centers for Environmental Prediction (NCEP) Climate Forecast System, version 2 (CFSv2), initialized with the Eu­ropean Centre for Medium-Range Weather Forecasts (ECMWF) global ocean reanalysis version 4, and observation-based land and atmosphere reanalyses. The results of this paper demonstrate that if the modern day climate models were available during the 1970's, even with the limited observations at that time, it should have been possible to predict the 1972-73 ENSO event and the associated monsoon drought. These results further suggest the necessity of continuing to develop realistic models of the climate system for accurate and reliable seasonal predictions. This paper also presents a comparison of the 1972-73 El Niño reforecast with the 1997-98 case. As the strongest event during 1958-78, the 1972-73 El Niño is distinguished from the 1997-98 one by its early termination. Initialized in the spring season, the forecast system predicted the onset and development of both events reasonably well, although the reforecasts underestimate the ENSO peaking magnitudes. On the other hand, the reforecasts initialized in spring and fall of 1972 persistently predicted lingering wind and SST anomalies in the eastern equatorial Pacific during the spring of 1973. Initialized in fall of 1997, the reforecast also grossly overestimates the peaking westerly wind and warm SST anomalies in the 1997-98 El Niño.In 1972-73, both the Eastern Pacific SST anomalies (for example Nino 3 Index) and the summer monsoon drought over India and the adjoining areas were predicted remarkably well. In contrast, the Eastern Pacific SST anomalies for the 1997-98 event were predicted well, but the normal summer monsoon rainfall over India of 1997 was not predicted by the model. This case study of the 1972-73 event is part of a larger, comprehensive reforecast project

  9. Geotechnical Issues in Total System Performance Assessments of Yucca Mountain

    International Nuclear Information System (INIS)

    HO, CLIFFORD K.; HOUSEWORTH, JIM; WILSON, MICHAEL L.

    1999-01-01

    A Total System Performance Assessment (TSPA) of Yucca Mountain consists of integrated sub-models and analyses of natural and engineered systems. Examples of subsystem models include unsaturated-zone flow and transport, seepage into drifts, coupled thermal hydrologic processes, transport through the engineered barrier system, and saturated-zone flow and transport. The TSPA evaluates the interaction of important processes among these subsystems, and it determines the impact of these processes on the overall performance measures (e.g., dose rate to humans). This paper summarizes the evaluation, abstraction, and combination of these subsystem models in a TSPA calculation, and it provides background on the individual TSPA subsystem components that are most directly impacted by geotechnical issues. The potential impact that geologic features, events, and processes have on the overall performance is presented, and an evaluation of the sensitivity of TSPA calculations to these issues is also provided

    Due to their properties, namely a high swelling capacity and a low hydraulic conductivity, Bentonites fulfil as geotechnical barrier a sealing and buffering function in the nuclear waste repository. Depending on the mineral composition Bentonites contain many suitable electron-donors and -acceptors, enabling potential microbial life. For the potential repository of highly radioactive waste the microbial mediated transformation of Bentonite could influence its properties as a barrier material. Microcosms were set up containing Bentonite and anaerobic synthetic Opalinus-clay-pore water solution under an N{sub 2}/CO{sub 2}-atmosphere to elucidate the microbial potential within selected Bentonites. Substrates like acetate and lactate were supplemented to stimulate potential microbial activity. First results show that bentonites represent a source for microbial life, demonstrated by the consumption of lactate and the formation of pyruvate. Furthermore, microbial iron-reduction was determined, which plays a crucial role in Betonite-transformation.

    Large quantities of oil-contaminated sands resulted from exploded oil wells, burning oil fires, the destruction of oil storage tanks, and the formation of oil lakes in Kuwait at the end of the Gulf War. An extensive laboratory testing program was carried out to determine the geotechnical characteristics of this material. Testing included basic properties, compaction and permeability tests, and triaxial and consolidation tests on clean and contaminated sand at the same relative density. Contaminated specimens were prepared by mixing the sand with oil in the amount of 6% by weight or less to match field conditions. The influence of the type of oil, and relative density was also investigated by direct shear tests. The results indicated a small reduction in strength and permeability and an increase in compressibility due to contamination. The preferred method of disposal of this material is to use it as a stabilizing material for other projects such as road construction

    The article examines primary causes of problems occurring during the drilling of geotechnical wells (injection, production and monitoring wells) for in-situ leaching to extract uranium in South Kazakhstan. Such a drilling problem as hole caving which is basically caused by various chemical and physical factors (hydraulic, mechanical, etc.) has been thoroughly investigated. The analysis of packing causes has revealed that this problem usually occurs because of insufficient amount of drilling mud being associated with small cross section downward flow and relatively large cross section upward flow. This is explained by the fact that when spear bores are used to drill clay rocks, cutting size is usually rather big and there is a risk for clay particles to coagulate

    2016-07-01

    Full Text Available Recent research regarding soil stabilization has been increasingly concerned with environmental performance. The present paper applies the newly developed CO2(eq geotechnical calculator, created by the European Federation of Foundation Contractors and the The Deep Foundations Institute, to assess the behavior of three different binders used in the construction of cutter-soil mixing columns, which formed an embankment/bridge transition wedge. The binders were based on ordinary Portland cement, on a blast furnace slag and cement blend and alkali activated fly ash. Results show that the last two binders are significabtly more effective, in terms of environmental performance, than the more traditional cement-based binder. Although the blast furnace slag cement, at this early stage of the geopolymeric binders, appears as the most interesting option, the fact that the CO2/cost ratio of both options is very similar stands out.

    This report contains a state-of-the-art review of the geotechnical assessment of Land 3 and Land 4 repository sites (at 100 - 300 m depth in rock) for intermediate level radioactive waste disposal. The principles established are also valid for the disposal of low and high level waste in rock. The text summarizes the results of 21 DoE research contract reports, firstly 'in series' by providing a technical review of each report and then 'in parallel' by considering the current state of knowledge in the context of the subjects in an interaction matrix framework. 1214 references are cited. It is concluded that four further research projects are required for site assessment procedures to be developed or confirmed. These are coupled modelling, mechanical properties, water flow and establishment of 2 phase site assessment procedures. (author)

    1986-01-01

    The compression behaviour of rock salt grit is being investigated by compression tests at the Asse salt mine. The various test parameters are introduced and their results are discussed. The permeability of rock salt grit with saturated NaCl-brine in dependency upon the grain size and compactness, resp. the porosity, is being determined at the Asse salt mine. The test equipment and the results determined here are shown. In addition to laboratory tests, geotechnical investigations are taking place in a carnallitic chamber of the Asse salt mine which had been backfilled in earlier years. They chiefly concern measurements of the deformation rates in drifts - which were mined between the chambers in remaining pillars - as well as horizontal deformation measurements in the backfilling.

    Freeman, T.J.

    1990-01-01

    The methods that might be used to bury radioactive waste in the deep ocean, and their likely effect on the sediment barrier, have been the subject of an international research program performed during the last ten years. This paper reviews the geotechnical aspects of deep ocean disposal and discusses how far the research performed has gone towards providing the information needed to assess this form of disposal. Considerable progress has been made during the course of the international program towards understanding the processes involved in the emplacement of heat generating waste (HGW) into the deep ocean bed and the subsequent interactions between the waste and the sediments. These processes do not appear to have a deleterious effect on the barrier properties of the sediments, and it is concluded that it is likely that HGW could be emplaced in the deep ocean in such a way that the seabed would provide an effective containment for the radionuclides

    CERN Document Server

    2017-01-01

    This book provides recent developments and improvements in the modeling as well as application examples and is a complementary work to the previous Lecture Notes Vols. 77 and 80. It summarizes the fundamental work from scientists dealing with the development of constitutive models for soils, especially cyclic loading with special attention to the numerical implementation. In this volume the neo-hypoplasticity and the ISA (intergranular strain anisotropy) model in their extended version are presented. Furthermore, new contact elements with non-linear constitutive material laws and examples for their applications are given. Comparisons between the experimental and the numerical results show the effectiveness and the drawbacks and provide a useful and comprehensive pool for all the constitutive model developers and scientists in geotechnical engineering, who like to prove the soundness of new approaches.

    An important step in the characterization of a high level nuclear waste repository is to demonstrate that geotechnical software, used in performance assessment, correctly models validation. There is another type of validation, called software validation. It is based on meeting the requirements of specifications documents (e.g. IEEE specifications) and does not directly address the correctness of the specifications. The process of comparing physical experimental results with the predicted results should incorporate an objective measure of the level of confidence regarding correctness. This paper reports on a methodology developed that allows the experimental uncertainties to be explicitly included in the comparison process. The methodology also allows objective confidence levels to be associated with the software. In the event of a poor comparison, the method also lays the foundation for improving the software

    1989-01-01

    Surface mining of coal from the Poker Flats mining area to the north of Healy, Alaska began in 1978. Current operations involve a 25 m/sup 3/ walking dragline which strips two coal seams, using an extended bench on the second pass; a fleet of trucks and shovels are used for coal removal and some limited overburden stripping. Geotechnical constraints to mining within the steeply dipping coal deposits are discussed. The area had a number of landslides. During 1984, mining operations close to a landslide caused movement to resume. A mine plan was developed which allowed the coal to be safely removed without inducing additional movement. This involves a dipline mining scheme through the slide area. Future mine plans will acknowledge the hazards of mining through potentially unstable zones. Aerial photographs, field mapping and geological exploration were used. 1 ref., 6 figs.

    Objectives We used findings from the Global Burden of Disease Study 2013 to report the burden of musculoskeletal disorders in the Eastern Mediterranean Region (EMR). Methods The burden of musculoskeletal disorders was calculated for the EMR's 22 countries between 1990 and 2013. A systematic analysis was performed on mortality and morbidity data to estimate prevalence, death, years of live lost, years lived with disability and disability-adjusted life years (DALYs). Results For musculoskeletal disorders, the crude DALYs rate per 100 000 increased from 1297.1 (95% uncertainty interval (UI) 924.3–1703.4) in 1990 to 1606.0 (95% UI 1141.2–2130.4) in 2013. During 1990–2013, the total DALYs of musculoskeletal disorders increased by 105.2% in the EMR compared with a 58.0% increase in the rest of the world. The burden of musculoskeletal disorders as a proportion of total DALYs increased from 2.4% (95% UI 1.7–3.0) in 1990 to 4.7% (95% UI 3.6–5.8) in 2013. The range of point prevalence (per 1000) among the EMR countries was 28.2–136.0 for low back pain, 27.3–49.7 for neck pain, 9.7–37.3 for osteoarthritis (OA), 0.6–2.2 for rheumatoid arthritis and 0.1–0.8 for gout. Low back pain and neck pain had the highest burden in EMR countries. Conclusions This study shows a high burden of musculoskeletal disorders, with a faster increase in EMR compared with the rest of the world. The reasons for this faster increase need to be explored. Our findings call for incorporating prevention and control programmes that should include improving health data, addressing risk factors, providing evidence-based care and community programmes to increase awareness.

    This paper describes the achievements at the Government Industrial Development Laboratory, Hokkaido in the Sunshine Project in fiscal 1990. Surveys were carried on different catalytic activities for co-liquefaction of various types of coals. The Ru system was found preferable in acquiring fatty family products of low boiling points. Reactions of co-liquefaction constituents do not progress independently, but have positive interaction. Adding Ru is effective in accelerating hydrogenation of condensed aromatic rings and hydrogenation of cleaving nucleus, but in view of the hydrogenating decomposition capability, the Mo-system may be better. In a liquefaction plant test, diesel oil was manufactured by reforming and improving the Yallourn coal light oil. However, the oxygen content was too high, aggravating the temperature distribution control in catalyst bed, and not having achieved the intended denitrification rate. Discussions were given on co-liquefaction of the depressurization residues of Cold Lake (CLVB[vacuum bottom])/Athabasca (ATVB) and Battle River coal. The CLCVB and ATVB were turned into lower molecules easily through hydrogenation treatment. The reaction characteristics reflected the characteristics of medium oil. Depolymerization of coal has progressed faster in ATVB. In the study on the engineering property values, discussions were given on behavior of solid particles in a bubble column, and gas hold-up of slurry. (NEDO)

    Full Text Available The physical properties of soils, which are tremendously influenced by the active clay minerals in soil, are of great importance in geotechnical engineering. This paper investigates the clay-sized particles of the Igbara-Odo pottery clay, and compares results obtained with available data on the bulk sample, to determine their correlation and underline the dependence of the geotechnical properties of the bulk clay material on the clay-sized particles. The bulk clay sample consists of 52% sand-size particles, 21% silt and 27% clay. Analysis of the clay-sized particles and the bulk materials shows: specific gravity of 2.07 and 2.66, liquid limit of 91.0% and 33.0%, plastic limit of 27.5% and 14.3%, plasticity index of 63.5% and 18.7% and a linear shrinkage of 7.9% and 5.4%, for both clay-sized particles and bulk clay respectively. The activity value of the clay material (0.64 suggests the presence of Kaolinite and Ilite; and these were confirmed with X-Ray diffraction on the bulk sample and clay-sized particles. X-Ray diffraction patterns shows distinctive peaks which highlight the dominance of Kaolinite (with 8 peaks in the pottery clay sample for both clay-sized particles and bulk material; while traces of other clay minerals like Illite and Halloysite and rock minerals like Mica, Feldspar and Chrysotile were also found. These results suggest that the clay possesses high viability in the manufacturing of ceramics, refractory bricks, paper, fertilizer and paint. The clay material can be used as a subgrade in road construction, since it possesses low swelling characteristics.

  9. Model tests of geosynthetic reinforced slopes in a geotechnical centrifuge

    2012-01-01

    Geosynthetic-reinforced slopes and walls became very popular in recent years because of their financial, technical, and ecological advantages. Centrifuge modelling is a powerful tool for physical modelling of reinforced slopes and offers the advantage to observe the failure mechanisms of the slopes. In order to replicate the gravity induced stresses of a prototype structure in a geometrically 1/N reduced model, it is necessary to test the model in a gravitational field N times larger than that of the prototype structure. In this dissertation, geotextile-reinforced slope models were tested in a geotechnical centrifuge to identify the possible failure mechanisms. Slope models were tested by varying slope inclination, tensile strengths of the geotextiles, and overlapping lengths. Photographs of the geotextile reinforced slope models in flight were taken with a digital camera and the soil deformations of geotextile reinforced slopes were evaluated with Particle Image Velocimetry (PIV). The experimental results showed that failure of the centrifuge models initiated at midheight of the slope, and occurred due to geotextile breakage instead of pullout. The location of the shear surface is independent of the tensile strength of the geotextile; it is dependent on the shear strength of the soil. It is logical to see that the required acceleration of the centrifuge at slope failure was decreased with increasing slope inclination. An important contribution to the stability of the slope models was provided by the overlapping of the geotextile layers. It has a secondary reinforcement effect when it was prolonged and passed through the shear surface. Moreover, the location of the shear surface observed with PIV analysis exactly matches the tears of the retrieved geotextiles measured carefully after the centrifuge testing. It is concluded that PIV is an efficient tool to instrument the slope failures in a geotechnical centrifuge.(author) [de

  14. Geotechnical Parameters of Alluvial Soils from in-situ Tests

    2012-10-01

    The article concentrates on the identification of geotechnical parameters of alluvial soil represented by silts found near Poznan and Elblag. Strength and deformation parameters of the subsoil tested were identified by the CPTU (static penetration) and SDMT (dilatometric) methods, as well as by the vane test (VT). Geotechnical parameters of the subsoil were analysed with a view to using the soil as an earth construction material and as a foundation for buildings constructed on the grounds tested. The article includes an analysis of the overconsolidation process of the soil tested and a formula for the identification of the overconsolidation ratio OCR. Equation 9 reflects the relation between the undrained shear strength and plasticity of the silts analyzed and the OCR value. The analysis resulted in the determination of the Nkt coefficient, which might be used to identify the undrained shear strength of both sediments tested. On the basis of a detailed analysis of changes in terms of the constrained oedometric modulus M0, the relations between the said modulus, the liquidity index and the OCR value were identified. Mayne's formula (1995) was used to determine the M0 modulus from the CPTU test. The usefullness of the sediments found near Poznan as an earth construction material was analysed after their structure had been destroyed and compacted with a Proctor apparatus. In cases of samples characterised by different water content and soil particle density, the analysis of changes in terms of cohesion and the internal friction angle proved that these parameters are influenced by the soil phase composition (Fig. 18 and 19). On the basis of the tests, it was concluded that the most desirable shear strength parameters are achieved when the silt is compacted below the optimum water content.

    The research was inspired by series of geological studies on Semanggol formation found exposed at North Perak, South Kedah and North Kedah. The chert unit comprised interbedded chert-shale rocks are the main lithologies sampled in a small-scale outcrop of Pokok Sena area. Black shale materials were also observed associated with these sedimentary rocks. The well-known characteristics of shale that may swell when absorb water and leave shrinkage when dried make the formation weaker when load is applied on it. The presence of organic materials may worsen the condition apart from the other factors such as the history of geological processes and depositional environment. Thus, this research is important to find the preliminary relations of the geotechnical properties of soft rocks and the geological reasoning behind it. Series of basic soil tests and 1-D compression tests were carried out to obtain the soil parameters. The results obtained gave some preliminary insight to mechanical behaviour of these two samples. The black shale and weathered interbedded chert-shale were classified as sandy-clayey-SILT and clayey-silty-SAND respectively. The range of specific gravity of black shale and interbedded chert/shale 2.3 – 2.6 and fall in the common range of shale and chert specific gravity value. In terms of degree of plasticity, the interbedded chert/shale samples exhibit higher plastic degree compared to the black shale samples. Results from oedometer tests showed that black shale samples had higher overburden pressure (Pc) throughout its lifetime compare to weathered interbedded chert-shale, however the compression index (Cc) of black shale were 0.15 – 0.185 which was higher than that found in interbedded chert-shale. The geotechnical properties of these two samples were explained in correlation with their provenance and their history of geological processes involved which predominantly dictated the mechanical behaviour of these two samples.

    Full Text Available http://dx.doi.org/10.17014/ijog.vol2no4.20074Volcanic gases, collected from Gendol and Woro solfatara fields, the summit of Merapi Volcano during 1990-1994, show an increase in chemical composition of H , CO, CO , SO , and HCl prior to the volcanic events, on the contrary to the drastic decreasing water vapour. The carbon/sulfur ratio of the volcanic gases lies between 1.5 and 5.7 which means that they were derived from the fresh magma. The Apparent Equilibrium Temperature (AET which is calculated from chemical compositions of volcanic gases using reaction of SO +3H = H S+2H O showed an increasing value prior to the volcanic events. The Merapi activities lasted during August 1990 to November 1994 showed a significant increase in ratio SO /H S prior to the November 1994 pyroclastic flow. The isotopic composition of volcanic gas condensates indicates that water vapour in Gendol is directly derived from the fresh magma. On the other hand, the contamination and cooling by the subsurface water occurred around the Woro field at a shallow part.

  15. Is there a link between per capita alcohol consumption and youth drinking? A time-series analysis for Sweden in 1972-2012.

    2015-06-01

    To estimate the relationship between per capita alcohol consumption and youth drinking in Sweden during the last 40 years and to estimate the relationship between female and male youth drinking during the 40-year study period. Per capita alcohol consumption was proxied by official sales data, supplemented by data on unrecorded consumption. Youth consumption was measured by a question on heavy episodic drinking (HED) included in an annual school survey of alcohol and drug habits among Swedish 9th -grade students (15-16 years of age). The annual samples comprise approximately 5000 individuals (with roughly equal numbers of boys and girls) with response rates in the range 80-93%. The study spans the period 1972-2012. Autoregressive integrated moving average (ARIMA) time-series analysis was used to estimate the relation between per-capita alcohol consumption and youth drinking. Ocular inspection of the time-series data suggested a stronger synchronization between the two series in the early period, before the mid-1990s, than in the later period, indicating a structural shift in the relation at issue. We therefore conducted period specific time-series analyses with 1995 as the year of division. There was a statistically significant relation between per capita alcohol consumption and HED among youth for 1972-94. A 1% increase in per capita alcohol consumption was associated with an increase in HED of 1.52% (P = 0.008). The estimate for 1995-2012 (0.12) was well below statistical significance (P = 0.580). The estimated elasticity of the association between boys' and girls' HED during 1972-94 was close to unity (0.98, P < 0.001), suggesting proportional changes in boys' and girls' drinking. When controlling for per capita consumption, the association was halved (to 0.55) but still significant in table 3 (P = 0.045).

    Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC). On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990-2013. We used Global Burden of Disease (GBD) 2013 data. Spatiotemporal Gaussian Process Regression (GPR) was applied to generate best estimates of child mortality with 95% uncertainty intervals (UI). Causes of death by age groups, sex, and year were measured using Cause of Death Ensemble modeling (CODEm). For estimation of HIV/AIDS mortality rate, the modified UNAIDS EPP-SPECTRUM suite model was used. Between 1990 and 2013 the under-5 mortality rate declined from 203.9 deaths/1000 live births to 74.4 deaths/1000 live births with an annual rate of change of 4.6%, yielding a total reduction of 64%. Similarly, child (1-4 years), post-neonatal, and neonatal mortality rates declined by 75%, 64%, and 52%, respectively, between 1990 and 2013. Lower respiratory tract infection (LRI), diarrheal diseases, and neonatal syndromes (preterm birth complications, neonatal encephalopathy, neonatal sepsis, and other neonatal disorders) accounted for 54% of the total under-5 deaths in 2013. Under-5 mortality rates due to measles, diarrhea, malaria, protein-energy malnutrition, and iron-deficiency anemia declined by more than two-thirds between 1990 and 2013. Among the causes of under-5 deaths, neonatal syndromes such as sepsis, preterm birth complications, and birth asphyxia ranked third to fifth in 2013. Of all risk-attributable deaths in 1990, 25% of the total under-5 deaths (112,288/435,962) and 48% (112,288/232,199) of the deaths due to diarrhea, LRI, and other common infections were

    In 1983, the National Marine Fisheries Service (NMFS) began a multiyear cooperative research program with the Bonneville Power Administration (BPA) to evaluate a new miniaturized identification system that could be used with salmonids. The system is referred to as the passive-integrated-transponder (PIT) tagging and interrogation system. The program has focused on determining the effects of PIT tags on juvenile and adult salmonids, as well as the development and evaluation of tagging and interrogation methods. Earlier results of the program have been reported in annual reports and journal articles cited in this report. This report covers the work per formed from 1990 through 1993. For convenience, the report is divided into three sections: (1) Interrogation and separation systems at Columbia River Basin dams; (2) Systems development and evaluation; and (3) Information and technology transfer.

    A geotechnical study has been completed in H-Area for the In-Tank Precipitation Facility (ITP) and the balance of the H-Area Tank Farm (HTF) at the Savannah River Site (SRS) in South Carolina. The study consisted of subsurface field exploration, field and laboratory testing, and engineering analyses. The purpose of these investigations is to evaluate the overall stability of the H-Area tanks under static and dynamic conditions. The objectives of the study are to define the site-specific geological conditions at ITP and HTF, obtain engineering properties for the assessment of the stability of the native soils and embankment under static and dynamic loads (i.e., slope stability, liquefaction potential, and potential settlements), and derive properties for soil-structure interaction studies.

    The Fifth International Symposium on Resonance Ionization Spectroscopy (RIS) and its Applications was held in Varese, Italy, 16-21 September 1990. Interest in RIS and its applications continues to grow, and RIS is expanding into a more diverse and mature field of study. This maturity was evident in this meeting both in the basic science and understanding of RIS processes and in the number of new and improved applications and techniques. The application of RIS techniques to molecular detection problems made remarkable progress since the last meeting two years ago. Subtle effects pertaining to isotopic discrimination received more theoretical attention, and there now seems to be good understanding of these effects, which can lead to correction procedures and/or methods to avoid isotopic effects. RIS applications were presented in which significant, real world problems were addressed, demonstrating its capability to solve problems that previously could not be accurately solved by other more traditional techniques. The contributions to the conference are grouped under the following major topic headings: physics applications of rare atoms; laser ionization mechanisms - spectroscopy; atomic, molecular and ion sources; molecular RIS; atomic RIS - Rydberg states; environmental trace analysis; biological and medical applications; state selected chemistry; new laser sources and techniques; ultra-high resolution and isotopic selectivity; surface and bulk analysis.

    We use a spatial Probit model to study the effect of contagion between banking systems of different countries. Applied to the late 1990s banking crisis in Asia we show that the phenomena of contagion is better seized using a spatial than a traditional Probit model. Unlike the latter, the spatial Probit model allows one to consider the cascade of cross and feedback effects of contagion that result from the outbreak of one initial crisis in one country or system. These contagion effects may result either from business connections between institutions of different countries or from institutional similarities between banking systems.

    Trenches and pits at the Radioactive Waste Management Complex (RWMC) Subsurface Disposal Area (SDA) at the Idaho National Engineering and Environmental Laboratory (formerly known as the Idaho National Engineering Laboratory) have been used for burial of radioactive waste since 1952. In 1985, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Energy, began a multi-phase study of the geohydrology of the RWMC to provide a basis for estimating the extent of and the potential for migration of radionuclides in the unsaturated zone beneath the waste trenches and pits. This phase of the study provides hydrologic and meteorological data collected at a designated test trench area adjacent to the northern boundary of the RWMC SDA from 1990 through 1996. The test trench area was constructed by the USGS in 1985. Hydrologic data presented in this report were collected during 1990-96 in the USGS test trench area. Soil-moisture content measurement from disturbed and undisturbed soil were collected approximately monthly during 1990-96 from 11 neutron-probe access holes with a neutron moisture gage. In 1994, three additional neutron access holes were completed for monitoring. A meteorological station inside the test trench area provided data for determination of evapotranspiration rates. The soil-moisture and meteorological data are contained in files on 3-1/2 inch diskettes (disks 1 and 2) included with this report. The data are presented in simple American Standard Code for Information Interchange (ASCII) format with tab-delimited fields. The files occupy a total of 1.5 megabytes of disk space

    As a result of economic reform commencing in 1978 in China, cultural beliefs of the Chinese business owners are changing. While much has been published concerning large and multinational businesses, there is a gap in knowledge Of cultural beliefs of small and medium sized enterprises. To provide new knowledge, a survey on these smaller sized enterprises located throughout China was conducted in the summer of 2006. Respondents were selected from urban and rural areas, coastal and inland provinces and various industries to provide information on their opinions on how some of their cultural beliefs have changed from 1990 to present. Specific beliefs questioned include: Use of fengshui, Traditional Forbidden Activities, Company Naming Responsibility, Company Name Basis, Use of Numbers, Use of Physiognomy, and Prediction of a Company's Future. The importance of fengshui has risen over in the last sixteen years and certain traditional forbidden activities such as not turning over the fish while eating has remained important as a cultural belief Naming a company is important and the desirability of a good name is based on various factors. Use of numbers, physiognomy, and non-scientific methods for predicting the future success of companies are of lesser use. These aspects of cuhure are reviewed in consideration of the change from a planned economy to a market-based economy.

    An analysis of 312 breast biopsies of 303 patients, performed during a 5-year period from April 1985 through March 1990 in a survey of the effects of exposure to A-bomb radiation, yielded the following findings. Sixty four (20.5%) of the 312 biopsies were in patients who had been exposed to A-bomb radiation or who had entered the city after the A-bombing, 10 of which were in patients exposed at up to 2,000 m from the hypocenter. Of the 64 biopsies performed for breast lesions in the exposed group, 42 (65.6%) yielded breast cancer. This figure was higher when compared with 47.0% (64 biopsies) of 136 patients who had been born before the A-bombing in the non-exposed group. In the exposed group, age distribution at the time of A-bombing was 11.9% in the first decade, 35.7% in the second decade, 31.0% in the third decade, 16.7% in the fourth decade, and 4.8% in the fifth decade. There was no correlation between histology type and exposure history in breast cancer. Nor did correlation exist between the age at the time of A-bombing and histology type in the exposed group.

    Full Text Available Irrigation projects in Egypt have been facing tremendous challenges, mostly is the scarcity of irrigation water. The current research presents the effect of different cohesive admixture on the conductivity of siliceous sand in general and its other geotechnical properties. Two different types of conventional swelling clay from (Toshka, 6th of October as well as bentonite were used to construct the irrigation canals and embankment. The results indicated that increase in the plasticity properties of the treated soil also decrease the permeability and infiltration. Moreover, the dry density of 2.08 t/m3 was obtained from sand and 20% 6th of October mixture, also the CBR of 31.20% were obtained from sand and 8% 6th of October mixture. Increasing the bentonite ratio increases the cohesion and decreasing the permeability. The swelling ratios of sand 6th of October Clay mixture is equal to 0.28%, and the fictitious stress at which the swelling ratio is nil, is equal to 16 kPa.

    Hemoglobinopathies are known as the most common genetic disorders in Iran. The paper aims to provide global estimates of deaths and disability adjusted life years (DALYs) due to hemoglobinopathies in Iran by sex and age during 1990 to 2010 and describe the challenges due to limitations of the Global Burden of Disease Study 2010 (GBD 2010). GBD 2010 estimates of the numbers of deaths and years of life lost (YLLs) due to premature mortality were calculated using the Cause of Death Ensemble model (CODEm). Years of life lost due to disability (YLDs) were computed by multiplication of prevalence, the disability weight for occurrence of sequelae, and the duration of symptoms. Prevalence was estimated through a systematic search of published and available unpublished data sources, with a Bayesian meta-regression model developed for GBD 2010. Disability weights were produced using collected data from population-based surveys. Uncertainty from all inputs was incorporated into the computations of DALYs using simulation methods. We aim to prepare and criticize the results of GBD 2010 and provide some recommendations for reaching better conclusions about the burden of hemoglobinopathies in Iran. Between 1990 and 2010, the overall deaths attributed to hemoglobinopathies decreased from 0.51% to 0.36% of total deaths, with the corresponding burden declining from 1% to 0.82% of total DALYs. There was a reduction in deaths and DALYs rates for all ages and the rates attributed to all ages followed the same pattern in Iranian men and women. The highest DALYs for hemoglobinopathies, thalassemia, sickle cell disorder, and glucose-6-phosphate dehydrogenase deficiency (G6PD-D) were found in those aged less than 5 years. The collective burden of all of these hemoglobin disorder was lower in 2010 than in 1990. Although the screening programs in Iran have been very successful in reducing the number of thalassemia patients between 1990 to 2010, in order to provide a better estimation of the

  18. Role to Be Played by Independent Geotechnical Supervision in the Foundation for Bridge Construction

    Science.gov (United States)

    Sobala, Dariusz; Rybak, Jarosław

    2017-10-01

    Some remarks concerning the necessity of employing an independent and over all ethical geotechnical survey were presented in the paper. Starting from the design phase, through the whole construction process, the importance of geotechnical engineer is stated in legal acts. Numerous testing technologies serve for the calibration of geotechnical technologies and allow for confirming the quality and capacity of piles. Special emphasis was payed to the involvement of scientifical and research institutions which can not only serve services but also can postprocess and methodize collected data. Such databases enable for new codes, methods and recommendations. Selection of deep foundations for bridge-type structures is most often dependent on complex geotechnical conditions, concentrated loads and constraints for pier displacements. Besides the last ones, prior to more common introduction of the design-construct system, could be a convenient justification for design engineer, who imposed deep foundation because he did not want or was not able to estimate the effect of pier settlement on civil engineering structure. The paper provides some notes about the need to engage a geotechnical supervising service of high competency and ethical quality during engineering and construction stages of foundations for bridge-type structures where legal requirements are of special consideration. Successive stages of projects are reviewed and research methods used for current calibration of geotechnical technologies and verification of geotechnical work quality are analysed. Special attention is given to potential involvement of independent R&D institutions which, apart from rendering specific services, also collect and systemize the research results thus enabling, in the long term, to revise engineering standards, instructions and guidelines.

    1976-01-01

    The Aftermath of the 1972-74 Drought in Nigeria is concerned with solutions to the problems associated with droughts. Case studies on small-farmers responses and attitudes to drought are included and a recurrent theme is the need to use these skills to encourage self reliance at the farm and village levels. Trees, particularly as shelter-belts are advocated, as in the provision of supplementary feed reserves for livestock. The use of groundwater as a drought reserve is discussed. A large section is devoted to the description of completed or projected irrigation schemes. Drought forecasting is briefly covered and the planning aspects of drought preparedness viewed from both theoretical and practical standpoints. Finally two valuable papers discuss the long-term storage of grain, one at national level and one at village level. The reviewer suggests that large-scale irrigation schemes will prove to be very expensive and will be less effective than low-technology, low water-use, low-cost development designed to supplement inadequate rainfall; i.e., life-saving irrigation. In addition, the book failed to adequately discuss the importance of providing small-scale farmers with the information that would maximize production, insure long-term storage and a guaranteed market at a reasonable price.

    Nowadays, geophysical prospecting is implemented in order to resolve a diversity of geological, hydrogeological, environmental and geotechnical problems. Although plenty of applications and a lot of research have been conducted in the countryside, only a few cases have been reported in the literature concerning urban areas, mainly due to high levels of noise present that aggravate most of the geophysical methods or due to spatial limitations that hinder normal method implementation. Among all geophysical methods, electrical resistivity tomography has proven to be a rapid technique and the most robust with regard to urban noise. This work presents a case study in the urban area of Chania (Crete Island, Greece), where electrical resistivity tomography (ERT) has been applied for the detection and identification of possible buried ancient ruins or other man-made structures, prior to the construction of a building. The results of the detailed geophysical survey indicated eight areas of interest providing resistivity anomalies. Those anomalies were analysed and interpreted combining the resistivity readings with the geotechnical borehole data and the historical bibliographic reports—referring to the 1940s (Xalkiadakis 1997 Industrial Archaeology in Chania Territory pp 51–62). The collected ERT-data were processed by applying advanced algorithms in order to obtain a 3D-model of the study area that depicts the interesting subsurface structures more clearly and accurately

    To document trends in the demographic and injury profile of new spinal cord injury (SCI) over time. Cross-sectional analysis of longitudinal data by injury years (1972-1979, 1980-1989, 1990-1999, 2000-2009, 2010-2014). Twenty-eight Spinal Cord Injury Model Systems centers throughout the United States. Persons with traumatic SCI (N=30,881) enrolled in the National Spinal Cord Injury Database. Not applicable. Age, sex, race, education level, employment, marital status, etiology, and severity of injury. Age at injury has increased from 28.7 years in the 1970s to 42.2 years during 2010 to 2014. This aging phenomenon was noted for both sexes, all races, and all etiologies except acts of violence. The percentage of racial minorities expanded continuously over the last 5 decades. Virtually among all age groups, the average education levels and percentage of single/never married status have increased, which is similar to the trends noted in the general population. Although vehicular crashes continue to be the leading cause of SCI overall, the percentage has declined from 47.0% in the 1970s to 38.1% during 2010 to 2014. Injuries caused by falls have increased over time, particularly among those aged ≥46 years. Progressive increases in the percentages of high cervical and motor incomplete injuries were noted for various age, sex, race, and etiology groups. Study findings call for geriatrics expertise and intercultural competency of the clinical team in the acute and rehabilitation care for SCI. This study also highlights the need for a multidimensional risk assessment and multifactorial intervention, especially to reduce falls and SCI in older adults.

    The substantial increase in life expectancy during recent decades has left all countries with a high number of elderly people that have particular health needs. Health policy-makers must be aware of the most prevalent causes of deaths and DALYs in this age group, as well as geriatric syndromes, in order to provide appropriate care and allocate resources in an equitable manner. The Global Burden of Disease study 2010 (GBD 2010), conducted by the institute for Health Metrics and Evaluation team, estimated the worldwide burden of diseases from 1990 to 2010. Its estimations were conducted on the basis of the proportion of deaths, the duration of symptoms and disability weights for sequelae, years lived with disability (YLDs), years of life lost (YLLs), and disability adjusted life years (DALYs) attributable to different diseases. In the present study, we extracted the data regarding the top five most prevalent causes of deaths, DALYs, and geriatric syndromes in the elderly based on the aforementioned GBD 2010, discussed the results using some tables and figures, reviewed the results, described the limitations of GBD 2010, and finally provided some recommendations as potential solutions. According to GBD 2010, the total number of deaths in Iran in 1990 was 321,627, of which 116,100 were in elderly people (those aged 60 years and above), meaning that 36.10% of all deaths occurred in the elderly. Among all diseases in this year, the first to third ranked causes of death were ischemic heart disease (IHD; 29.44%), neoplasms (13.52%), and stroke (7.24%). In comparison, the total number of deaths in Iran increased to 351,814 in 2010, with 213,116 of these occurring in the elderly (60.58% of deaths), but the most prevalent causes of death remained the same as in 1990. The highest 1990 DALYs rates were the result of IHD (21.56%), neoplasms (10.70%), and stroke (4.85%). IHD (22.77%), neoplasms (9.48%), and low back pain (LBP; 5.72%) were the most prevalent causes of DALYs in

    During the 1970s, a growing number of medical schools began to recognize the importance of medical education concerning human sexuality. Currently, most medical schools provide at least some instruction in human sexuality. In light of this development, the present study aimed to compare the interest in and knowledge about human sexuality of medical students from two different time periods. The answers to a self-constructed questionnaire of 236 students in 1972 were compared with those of 259 students in 2012. Students were asked whether they were interested in education regarding human sexuality and which specific topics they felt should be included in the medical curriculum. The students' knowledge in the following domains was assessed: sexual development, sexual behavior, sexual physiology and psychology, and sexual medicine. The two cohorts were compared with regard to those specific sexuality-related topics in which the students were most and least interested in. Furthermore, the number of correct responses to the knowledge questions was compared. While in 1972, 99.2% of the students were interested in medical education about human sexuality, in 2012, 80.3% showed an interest. The connection of disorders from different medical disciplines with sexuality was rated as most interesting by both the students from 1972 and 2012. Medical students from 2012 gave 50.3% correct answers to the knowledge questions, whereas students from 1972 correctly answered 46.3% of the questions. Although interest in education concerning human sexuality has decreased, the majority of students view it as an important topic. Nevertheless, medical students still lack knowledge about important aspects of human sexuality (e.g., psychosexual development and relative safety of different contraceptives). Therefore, more time should be dedicated to education concerning human sexuality and its cultural, societal, and health aspects in particular. © 2014 International Society for Sexual Medicine.

    We report analyses of a dataset spanning 38 years of near-annual fishing for Antarctic toothfish Dissostichus mawsoni, using a vertical setline through the fast ice of McMurdo Sound, Antarctica, 1972-2010. This constitutes one of the longest biological time series in the Southern Ocean, and certainly the longest for any fish. Fish total length, condition and catch per unit effort (CPUE) were derived from the more than 5500 fish caught. Contrary to expectation, length-frequency was dominated by fish in the upper half of the industrial catch. The discrepancy may be due to biases in the sampling capabilities of vertical (this study) versus benthic (horizontal) fishing gear (industry long lines), related to the fact that only large Antarctic toothfish (more than 100 cm TL) are neutrally buoyant and occur in the water column. Fish length and condition increased from the early 1970s to the early 1990s and then decreased, related to sea ice cover, with lags of 8 months to 5 years, and may ultimately be related to the fishery (which targets large fish) and changes in the Southern Annular Mode through effects on toothfish main prey, Antarctic silverfish Pleuragramma antarcticum. CPUE was constant through 2001 and then decreased dramatically, likely related to the industrial fishery, which began in 1996 and which concentrates effort over the Ross Sea slope, where tagged McMurdo fish have been found. Due to limited prey choices and, therefore, close coupling among mesopredators of the Ross Sea, Antarctic toothfish included, the fishery may be altering the trophic structure of the Ross Sea.

  17. Development of a debris flow model in a geotechnical centrifuge

    Debris flows occur in three main stages. At first the initial soil mass, which rests in a rigid configuration, reaches a critic state releasing a finite mass over a failure surface. In the second stage the released mass starts being transported downhill in a dynamic motion. Segregation, erosion, entrainment, and variable channel geometry are among the more common characteristics of this stage. Finally, at the third stage the transported mass plus the mass gained or loosed during the transportation stage reach a flat and/or a wide area and its deposition starts, going back to a rigid configuration. The lack of understanding and predictability of debris flow from the traditional theoretical approaches has lead that in the last two decades the mechanics of debris flows started to be analysed around the world. Nevertheless, the validation of recent numerical advances with experimental data is required. Centrifuge modelling is an experimental tool that allows the test of natural processes under defined boundary conditions in a small scale configuration, with a good level of accuracy in comparison with a full scale test. This paper presents the development of a debris flow model in a geotechnical centrifuge focused on the second stage of the debris flow process explained before. A small scale model of an inclined flume will be developed, with laboratory instrumentation able to measure the pore pressure, normal stress, and velocity path, developed in a scaled debris flow in motion. The model aims to reproduce in a controlled environment the main parameters of debris flow motion. This work is carried under the EC 7th Framework Programme as part of the MUMOLADE project. The dataset and data-analysis obtained from the tests will provide a qualitative description of debris flow motion-mechanics and be of valuable information for MUMOLADE co-researchers and for the debris flow research community in general.

    Full Text Available Abstract Background Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC. On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990–2013. Methods We used Global Burden of Disease (GBD 2013 data. Spatiotemporal Gaussian Process Regression (GPR was applied to generate best estimates of child mortality with 95% uncertainty intervals (UI. Causes of death by age groups, sex, and year were measured using Cause of Death Ensemble modeling (CODEm. For estimation of HIV/AIDS mortality rate, the modified UNAIDS EPP-SPECTRUM suite model was used. Results Between 1990 and 2013 the under-5 mortality rate declined from 203.9 deaths/1000 live births to 74.4 deaths/1000 live births with an annual rate of change of 4.6%, yielding a total reduction of 64%. Similarly, child (1–4 years, post-neonatal, and neonatal mortality rates declined by 75%, 64%, and 52%, respectively, between 1990 and 2013. Lower respiratory tract infection (LRI, diarrheal diseases, and neonatal syndromes (preterm birth complications, neonatal encephalopathy, neonatal sepsis, and other neonatal disorders accounted for 54% of the total under-5 deaths in 2013. Under-5 mortality rates due to measles, diarrhea, malaria, protein-energy malnutrition, and iron-deficiency anemia declined by more than two-thirds between 1990 and 2013. Among the causes of under-5 deaths, neonatal syndromes such as sepsis, preterm birth complications, and birth asphyxia ranked third to fifth in 2013. Of all risk-attributable deaths in 1990, 25% of the total under-5 deaths (112,288/435,962 and 48% (112,288/232,199 of the deaths due to

    Socioeconomic disparities in the food environment are known to exist but with little understanding of change over time. This study investigated the density of takeaway food outlets and presence of supermarkets in Norfolk, UK between 1990 and 2008. Data on food retail outlet locations were collected from telephone directories and aggregated within electoral wards. Supermarket presence was not associated with area deprivation over time. Takeaway food outlet density increased overall, and was significantly higher in more deprived areas at all time points; furthermore, socioeconomic disparities in takeaway food outlet density increased across the study period. These findings add to existing evidence and help assess the need for environmental interventions to reduce disparities in the prevalence of unhealthy food outlets. PMID:25841285

  15. Radioactivity in foodstuffs 1990

    International Nuclear Information System (INIS)

    1991-01-01

    The average per capita radiation dose received by the Norwegian population due to intake of foodstuffs in 1990 was between 0.03 and 0.06 mSv. This was about the same level as in previous years since the Chernobyl accident. Certain individuals with special dietary habits (consumption of large amounts of freshwater fish and reindeer), and who live in heavily contaminated areas, received higher doses (appr. 1 mSv). In 1990 dietary advice was maintained with regard to people consuming large amounts of reindeer meat and/or game and freshwater fish. The aim is still that no person shall be exposed to an annual dose of more than 1 mSv through food. The present report reviews the data concerning radioactivity levels in dairy products, meat and fish for 1990. Levels were similar to those recorded in the previous year, but considerably lower than those in 1988. The report also presents some data from a 5-year radio-ecological research programme carried out by the Norwegian Institute of Nature Research (NINA). In general, levels in wild fish and game were below the intervention limit of 6000 Bq/kg, apart from a few reindeer herds and fish from a few localities. 8 figs. 6 tabs

    The abnormal increase of cosmic ray on Aug. 7th particularly the dependence of its starting time on local time was studied. Cosmic ray increased twice before and after the greatest Forbush decrease in history on August 4th and 7th, 1972. This study is a trial to estimate the anisotropic flow of solar cosmic ray from the time difference time at different places. Further, the past instance of 23 ground-level events were statistically restudied, and the relationship between the time of generation of solar cosmic ray and the time of transmission to the earth was investigated. A list is given regarding the solar cosmic ray of more than 10 9 eV which occurred since the observation had started. The list shows definite three groups. Attention is paid to the transmission time of F type which is considered to have the most simplest transmission mechanism. The dispersion of the transmission time is large regarding flare-starting time and peak wave intensity time, but is small regarding solar wave-starting time, but the dependence on the longitude is systematic. After all, cosmic ray is accelerated after 10 minutes since solar electric wave has started, and arrives at the earth most early in the case of a flare occurred at the root of garden force line toward the earth. In conclusion, the method of studying the difference of the starting time of abnormal increase according to local time may be an effective means for examining in the characteristics of anisotropic flow of solar cosmic ray.

    The purpose of this paper is to implement an interface using tool to pack the GIS application to carry out a field inspection. The solution was implemented on pocket equipment using a simplified map and database integrated with the GIS Corporative. The main objective is to avoid paper work in field inspections. The emphases are on geotechnical inspections in order to assist the recuperation of information about points with geotechnical risk. There are interfaces with external device as GPS for insertion of points of risk. A set of tools are developed for bidirectional synchronization among the Corporative GIS and the pocket devices. The project focused geotechnical inspections on field, in order to synchronize automatically the information collected with the pocket GIS application with a Web server, packing all information from field operation to managers.

    Full Text Available Discarded waste tires are becoming a serious threat to health, environment, and ecological systems worldwide if it is not disposed of properly. Every year 1000 million of waste tires are discarded. This number may grow up to 1200 million by the year 2030. On the other hand, construction of civil engineering structures such as buildings, dams, highways, etc. are at high risk of differential settlement, especially in the case of weak or soft clay, which is due to its low shear strength and high compressibility. The paper aims to assess geotechnical properties of uncemented/cemented clayey soil incorporated with waste crumb rubber. Compaction parameters, unconfined compressive strength, split tensile strength, toughness index, CBR values and swelling pressure of rubberized uncemented/cemented clayey soil (3%, and 6% cement and different percentage of crumb rubber have been obtained. After rigorous extensive study, it has been concluded that unconfined compressive strength and split tensile strength of rubberized cemented clayey soil decreases with the increase of the percentage of crumb rubber whereas the axial, and diametral strain are found to be increased with the addition of crumb rubber up to 5% after that it starts to decrease. The CBR values, swelling pressure, and toughness index of uncemented/cemented clayey soil was significantly affected by incorporation of crumb rubber. SEM studies have also been incorporated in this investigation.

    Full Text Available Background: This study uses data of the global burden of diseases (GBD study 2010 to report death, disability-adjusted life year (DALYs, years of life lived with disability (YLDs and years of life lost due to premature mortality (YLLs, attributed to suboptimal breastfeeding by age and gender during 1990 to 2010 in Iran. Materials and Methods:The GBD assessments were used, together with estimates of death and DALYs due to specific risk factors to calculate the attributed burden of each risk factor exposure compared with the theoretical-minimum-risk exposure. Uncertainties in the distribution of exposure, relative risks, and relevant outcomes were incorporated into estimates of mortality attributable and burden and were presented as 95 % uncertainty interval (UI. Results:In both genders, the age standardized DALYs rates and the age standardized death rate [(from 5 (95% UI: 2-8 to 1 (95% UI: 0-2 per 100,000 populations], attributed to breastfeeding, had a decreasing trends. The age standardized YLD rate increased from 7 (95% UI: 2-15 to 10 (95% UI: 3-23 per 100,000 populations in boys and, from 7(95% UI: 2-16 to 11(95% UI: 3-26 per 100,000 populations in girls. The YLD changes showed some variation according to age categories. For both genders, the age standardizes YLL rate decreased from 395 (95% UI: 185-681 per 100,000 populations to 111(95% UI: 42-213 per 100,000 populations. Conclusion: The burden attributed to suboptimal breastfeeding had a considerable reduction rate from 1990 to 2010.

    The aim of the study was to identify predictors for the transition from long-term sickness absence into disability pension with a special focus on gender. The study used data from a national database containing a 10% random sample of the Norwegian adult population (The KIRUT database). The study population were all individuals in the database who on 1 January 1990 were eligible for sick pay from the Norwegian National Insurance System: 83,398 men and 75,586 women. Individuals below 60 years with long-term sickness absence starting in 1990 and 1991 were identified, 6,434 men and 8,233 women, and followed up for three years. Background data were used as independent variables in a logistic regression of the probability for receiving disability pension during follow-up. Annual cumulative incidence of long-term sickness absence was 6.5% for women and 4.9% for men. During follow-up, 12.4% of the women and 12.6% of the men received disability pension. Among full-time employed women only 10.3% had become disability pensioners, while the corresponding proportion for women working part-time was 15.5%. For men the figures were 12.1% (full-time) and 18.1% (part-time). In the logistic regression of the whole sample the female odds ratio was insignificant. The dominant predictive factors for disability pension were age and duration of the sickness spells. Working part-time also increased the risk. Higher levels of education and having children below 7 years reduced the probability for disability pension. Separate regressions for men and women showed that the 'protective' effect of having small children only remained for women.

    BACKGROUND:Measuring disease and injury burden in populations requires a composite metric that captures both premature mortality and the prevalence and severity of ill-health. The 1990 Global Burden of Disease study proposed disability-adjusted life years (DALYs) to measure disease burden...... with strictly comparable definitions and methods. YLLs were calculated from age-sex-country-time-specific estimates of mortality by cause, with death by standardised lost life expectancy at each age. YLDs were calculated as prevalence of 1160 disabling sequelae, by age, sex, and cause, and weighted by new....... In sub-Saharan Africa, however, many communicable, maternal, neonatal, and nutritional disorders remain the dominant causes of disease burden. The rising burden from mental and behavioural disorders, musculoskeletal disorders, and diabetes will impose new challenges on health systems. Regional...

    Coincident with the advent of mammography screening, breast carcinoma in situ has increased in the US population. We conducted a prospective cohort study of all women presenting with primary breast cancer, aged 21–94, and biopsy confirmed Stage 0-IV from 1990–2005 identified and tracked by our registry. Clinical presentation characteristics including age, race, TNM stage, family and pregnancy history, histologic type and method of detection by patient (PtD), physician (PhysD) or mammography (MgD) were chart abstracted at time of diagnosis. Cases with unknown or other method of detection (n = 84), or unusual cell types (n = 26) were removed (n = 6074). From 1990 to 1998 the percentage of PtD and MgD cases was roughly equivalent. In 1999 the percentage of MgD cases increased to 56% and PtD dropped to 37%, a significant 20% differential, constant to 2005 (Pearson chi square = 120.99, p < .001). Overall, percent TNM stage 0 (breast carcinoma in situ) cases increased after 1990, percent stage I and III cases declined, and stage II and IV cases remained constant (Pearson chi square = 218.36, p < .001). Increase in MgD over time differed by age group with an 8.5% increase among women age 40–49 and 12% increase among women age 50–95. Women age 21–39 rarely had MgD BC. In forward stepwise logistic regression modeling, significant predictors of MgD BC by order of entry were TNM stage, age at diagnosis, diagnosis year, and race (chi square = 1867.56, p < .001). In our cohort the relative proportion of mammography detected breast cancer increased over time with a higher increase among women age 50+ and an increase of breast carcinoma in situ exclusively among MgD cases. The increase among women currently targeted by mammography screening programs (age ≥ 50) combined with an increase of breast carcinoma in situ most often detected by mammography screening indicates a possible incidence shift to lower stage breast cancer as a result of mammographic detection

  15. Integrating weather and geotechnical monitoring data for assessing the stability of large scale surface mining operations

    Directory of Open Access Journals (Sweden)

    Steiakakis Chrysanthos

    2016-01-01

    Full Text Available The geotechnical challenges for safe slope design in large scale surface mining operations are enormous. Sometimes one degree of slope inclination can significantly reduce the overburden to ore ratio and therefore dramatically improve the economics of the operation, while large scale slope failures may have a significant impact on human lives. Furthermore, adverse weather conditions, such as high precipitation rates, may unfavorably affect the already delicate balance between operations and safety. Geotechnical, weather and production parameters should be systematically monitored and evaluated in order to safely operate such pits. Appropriate data management, processing and storage are critical to ensure timely and informed decisions.

    2012-12-01

    Bacteria or microbes in soil excrete hydrocarbon (e.g. polysaccharide) by-products which are called biopolymers. These biopolymers (or sometime biofilms) recently begun to make a mark on soil erosion control, aggregate stabilization, and drilling enhancement. However, the biological effect on soil behavior (e.g. bio-clogging or bio-cementation) has been poorly understood. In this study, the bio-cementation and bio-clogging effect induced by the existence of β-1,3/1,6-glucan biopolymers in soil were evaluated through a series of geophysical and geotechnical characterization tests in laboratory. According to the experimental test results, as the β-1,3/1,6-glucan content in soil increases, the compressive strength and shear wave velocity increase (i.e., bio-cementation) while the hydraulic conductivity decreases (i.e., bio-clogging) but the electrical conductivity increases due to the high electrical conductivity characteristic of β-1,3/1,6-glucan fibers. Coefficient of consolidation variation with the increases of β-1,3/1,6-glucan content in soil. SEM image of β-1,3/1,6-glucan treated soil. Fibers are form matices with soil particles.

    2017-04-01

    Full Text Available This study assesses the geotechnical characteristics of lateritic soil and sawdust ash lime (SDAL mixtures. Preliminary tests were carried out on the natural soil sample for identification and classification purposes. The sawdust was mixed with lime for stabilization in the ratio 2:1. This mixture was thereafter added to the lateritic soil in varying proportions of 2, 4, 6, 8 and 10% by weight of soil. Addition of SDAL increased values of Optimum Moisture Content (OMC from 17.0% at 0% SDAL to 26.5% at 10% SDAL by weight of soil, also, values of Maximum Dry Density (MDD decreased from 2040 kg/m3 at 0% SDAL to 1415 kg/m3 at 10% SDAL. Values of Unconfined Compressive Strength (UCS increased from 38.58 kN/m2 at 0% SDAL to highest value of 129.63 kN/m2 at 6% SDAL. The values of liquid limits and plasticity index of the soil were effectively reduced with the addition of the SDAL, from 54.0% at 0% SDAL to 49.0% at 10% SDAL and from 13.7% at 0% SDAL to 12.5% at 10% SDAL respectively. It was therefore concluded that the sawdust ash lime (SDAL mixture can serve as a cheap soil stabilizing agent for poor lateritic soil.

    Otani, J; Watanabe, Y; Chevalier, B

    2010-01-01

    In this paper, fundamental issues on the use of X-ray CT to geomaterials were discussed, which were the contents of what you have to know about the use of X-ray CT, especially for geomaterials or granular materials. Then, two of our recent studies were introduced, which are 1) the use of X-ray CT data to quantitative measurements such as deformation and strains and 2) comparison of X-ray CT results with numerical analysis. Here, the triaxial compression test on sand was conducted and the image analysis technique called 'Digital Image Correlation' was used to measure displacement and strain fields in the soils using a large number of CT images. For the second topic, one of the advantages on the use of X-ray CT is to investigate the behavior in three dimensions. Here, so called trap door test was conducted with the materials of glass beads and the shape of the square door. DEM analysis was also conducted for the simulation of this behaviour and both results were compared. Based on all the results in this paper, the effectiveness of the use of X-ray CT in geomechanics and geotechnical engineering was revealed.

    2016-03-01

    The use of recycled aggregates (RA) in construction constitutes a significant step towards a more sustainable society and also creates a new market opportunity to be exploited. In recent years, several case-studies have emerged in which RA were used in Geotechnical applications, such as filling materials and in unbound pavement layers. This paper presents a review of the most important physical properties of different types of RA and their comparison with natural aggregates (NA), and how these properties affect their hydraulic and mechanical behaviour when compacted. Specifically, the effects of compaction on grading size distribution curves and density are analysed, as well as the consequences of particle crushing on the resilient modulus, CBR and permeability. The paper also contains an analysis of the influence of incorporating different RA types on the performance of unbound road pavement layers as compared with those built with NA by means of the International Roughness Index and deflection values. The results collected from the literature indicate that the performance of most RA is comparable to that of NA and can be used in unbound pavement layers or in other applications requiring compaction.

  20. Utilization of multimode Love wave dispersion curve inversion for geotechnical site investigation

    International Nuclear Information System (INIS)

    Hamimu, La; Nawawi, Mohd; Safani, Jamhir

    2011-01-01

    Inversion codes based on a modified genetic algorithm (GA) have been developed to invert multimode Love wave dispersion curves. The multimode Love wave dispersion curves were synthesized from the profile representing shear-wave velocity reversal using a full SH (shear horizontal) waveform. In this study, we used a frequency–slowness transform to extract the dispersion curve from the full SH waveform. Dispersion curves overlain in dispersion images were picked manually. These curves were then inverted using the modified GA. To assess the accuracy of the inversion results, differences between the true and inverted shear-wave velocity profile were quantified in terms of shear-wave velocity and thickness errors, E S and E H . Our numerical modeling showed that the inversion of multimode dispersion curves can significantly provide the better assessment of a shear-wave velocity structure, especially with a velocity reversal profile at typical geotechnical site investigations. This approach has been applied on field data acquired at a site in Niigata prefecture, Japan. In these field data, our inversion results show good agreement between the calculated and experimental dispersion curves and accurately detect low velocity layer targets

    1976-10-01

    A review is presented of the interplanetary magnetic field observations acquired in early August 1972 when four solar flares erupted in McMath Plage region 1976. Measurements of the interplanetary field were obtained by Earth satellites, HEOS-2 and Explorer 41, and by Pioneers 9 and 10 which, by good fortune, were radially aligned and only 45/sup 0/ east of the Earth-Sun direction. In response to the four flares, four interplanetary shocks were seen at Earth and at Pioneer 9, which was then at a heliocentric distance of 0.78 AU. However, at Pioneer 10, which was 2.2 AU from the Sun, only two forward shocks and one reverse shock were seen. The available magnetic field data acquired in the vicinity of the shocks are presented. Efforts to identify corresponding shocks at the several locations and to deduce their velocities of propagation between 0.8 and 2.2 AU are reviewed. The early studies were based on average velocities between the Sun and Pioneer 9, the Sun and Earth and the Sun and Pioneer 10. A large deceleration of the shocks between the Sun and 0.8 AU as well as between 0.8 and 2.2 AU was inferred. More recently the local velocities of the shocks at Pioneers 9 and 10 have become available. A comparision of these velocities shows little, if any, deceleration between 0.8 and 2.2 AU and implies that most or all of the deceleration actually occurred nearer the Sun. Evidence is also presented that shows a significant departure of the flare-generated shock fronts from spherical symmetry.

This serious threat to health care is further exacerbated by the limited epidemiological information about the common zoonotic agent, Salmonella enteritidis, required to determine antibiotic therapy. The aim was to characterise the antimicrobial resistance patterns of S. enteritidis isolates across different timelines (1972–2005 with accompanying genetic changes being investigated. Thirty-seven stored S. enteritidis isolates were collected from the Central Veterinary Laboratory, Harare, with antimicrobial susceptibility determined against eight antibiotics. Plasmids were isolated to analyse any genetic variation. An overall significant increase in resistance (p < 0.05 to nalidixic acid (0% – 10%, ampicillin (14.3% – 50%, tetracycline (14.3% – 30% and erythromycin (71.4% – 100% was observed across the timeline. However, the highest rates of susceptibility were maintained for gentamicin, sulphamethoxazole-trimethoprim, kanamycin and chloramphenicol. We report an increase in multidrug resistance (MDR of 14.2% – 50% with an increase in resistotypes and plasmid profiles across the timeline. Eleven plasmid profiles were obtained in the 37 isolates studied with a minority of isolates (21.6%, 8/37 harbouring a 54 kb plasmid, commonly serovar-specific. A concerning increase in antimicrobial resistance to commonly administered drugs was observed across the timeline. The surge in MDR is of great concern and implies the need for consistent antimicrobial stewardship. No correlation was observed between the plasmid and antibiotic profiles.

    As part of the NSF-funded Geotechnical Extreme Events Reconnaissance (GEER) Association response to Hurricane Harvey, a team of engineers and scientists mobilized to the coastal cities of Texas, USA from 1 to 5 September 2017. Damage to coastal and riverine structures due to erosion by storm surge, waves, and coastal and riverine flooding was assessed in a wide coastal zone between Corpus Christi and Galveston. Making initial landfall near Rockport, Texas on 26 August 2017, Hurricane Harvey was classified as a category 4 hurricane on the Saffir-Simpson scale with wind speeds exceeding 130 mph and an atmospheric pressure of 938 mbar. The storm stalled over the Houston area, pouring 40 inches of rain on an area encompassing more than 3,000 square miles. Hurricane Harvey, which remained a named storm for 117 hours after initial landfall, slowly moved east into the Gulf of Mexico and made final landfall near Cameron, Louisiana on 30 August. The GEER team surveyed sixteen main sites, extending from Mustang Island in the southwest to Galveston in the northeast and as far inland as Rosenburg. In Port Aransas, beach erosion and undercutting along a beach access road near Aransas Pass were observed. Due to several tide gauge failures in this area, the nearest NOAA tide gauge (#8775870 near Corpus Christi) was used to estimate water levels of 1.35 m, approximately 1.0 m above the predicted tide. In Holiday Beach, anchored retaining walls were inundated, causing backside scour along the entire length and exposing the sheetpile wall anchors. Along the Colorado River at the Highway 35 bridge near Bay City, active riverbank failure was observed and a sheet pile wall was found collapsed. Significant sediment deposits lined the vegetated riverbanks. A USGS stream gage recorded gage heights greater than 45 ft, exceeding the flood stage of 44 ft. Fronting a rubblemound seawall in Surfside Beach, a runnel and ridge formation was observed. Nearby at San Luis Pass, infilled scour

    In February 2015, two Eurasian collared doves (Streptopelia decaocto) were submitted dead to the California Animal Health and Food Safety (CAHFS) Laboratory, Turlock branch, from a private aviary experiencing sudden, high mortality (4/9) in adult doves. In both doves, the gross and histologic lesions were indicative of acute, fatal septicemia. Grossly, there were numerous pale yellow foci, 1 to 2 mm in diameter, in the liver and spleen. Microscopically, these foci were composed of acute severe multifocal coagulative necrosis of hepatocytes and splenic pulp with infiltration of heterophils mixed with fibrin and dense colonies of gram-negative bacteria. Yersinia pseudotuberculosis was isolated from the lung, liver, spleen, heart, ovary, kidney, and trachea. The organism was susceptible to most antibiotics it was tested against, except erythromycin. Based on a retrospective study of necropsy submissions to CAHFS between 1990 and 2015, there were 77 avian case submissions of Y. pseudotuberculosis. There were 75/77 cases identified from a wide range of captive avian species from both zoo and private facilities and 2/77 cases from two backyard turkeys submitted from one premise. The largest number of cases originated from psittacine species (31/77). The lesions most commonly described were hepatitis (63/77), splenitis (49/77), pneumonia (30/77), nephritis (16/77), and enteritis (12/77). From 1990 to 2015, there was an average of three cases of avian pseudotuberculosis per year at CAHFS. Although there were no cases diagnosed in 1993 and 1994, in all other years, there were between one and eight cases of Y. pseudotuberculosis detected from avian diagnostic submissions.

    Work at Institutt for energiteknikk (IFE) comprises both nuclear and non-nuclear activities. Nuclear power research at the Institute is performed within the international OECD Halden Reactor Project. More than 40 organizations in eight European countries, plus USA and Japan, participated in the 1988 to 1990 phase of the project. The next agreed phase, 1991 to 1993, will see the list of participants expanded to include two new OECD countries, Spain and Switzerland. Key factors under investigation in the fuel and materials technology area include the operational reliablility of reactor fuel and changes in material properties under varying conditions of radiation and water chemistry. Progress has been satisfactory on the fuel and materials test program, and about 40 different fuel element designs have been tested. The information technology activities centre on an advanced control room coupled to a full scale simulator of a nuclear power station of the pressurized water type (PWT). The experiments, aimed at developing new informations systems for energy and process industries, are carried out by process operators from the Halden reactor. During 1990, an extensive program has been carried out to test a computer-based operation procedure system. The results show that this system, in certain operational situations, provides the operator with better information support than conventional handbooks of written procedures. A number of areas in which the system could be improved were also identified, and the development of a new ''second generation'' system was started in 1990. The new system will be implemented on UNIX-based work stations, using so-called open system standards in order to facilitate transfer of the system to different users. Testing has also been started on an operator support system for diagnosis on the primary causes of plant disturbances. 22 figs

    The Particle Imaging Velocimetry (PIV) technique is being used to measure soil displacements. PIV has been used for many years in fluid mechanics; but for physical modeling in geotechnical engineering, this technique is still relatively new. PIV is a worldwide growth in soil mechanics over the last decade owing to the developments in digital cameras and laser technologies. The use of PIV is feasible provided the surface contains sufficient texture. A Cambridge group has shown that natural sand contains enough texture for applying PIV. In a texture-based approach, the only requirement is for any patch, big or small to be sufficiently unique so that statistical tracking of this patch is possible. In this paper, some of the soil mechanic's models were investigated such as retaining walls, slope failures, and foundations. The photographs were taken with the help of the high resolution digital camera, the displacements of soils were evaluated with free software named as MatPIV and the displacement graphics between the two images were obtained. Nikon D60 digital camera is 10.2 MB and it has special properties which makes it possible to use in PIV applications. These special properties are Airflow Control System and Image Sensor cleaning for protection against dust, Active D-Lighting for highlighted or shadowy areas while shooting, advanced three-point AF system for fast, efficient and precise autofocus. Its fast and continuous shooting mode enables up to 100 JPEG images at three frames per second. Norm Sand (DIN 1164) was used for all the models in a glass rectangular box. For every experiment, MatPIV was used to calculate the velocities from the two images. MatPIV program was used in two ways such as easy way and difficult way: In the easy way, the two images with 64*64 pixels with 50% or 75% overlap of the interrogation windows were taken into consideration and the calculation was performed with a single iteration through the images and the result consisted of four

    The near surface ground conditions are highly important for the design of civil constructions. These conditions determine primarily the ability of the foundation formations to bear loads, the stress - strain relations and the corresponding deformations, as well as the soil amplification and corresponding peak ground motion in case of dynamic loading. The static and dynamic geotechnical parameters as well as the ground-type/soil-category can be determined by combining geotechnical and geophysical methods, such as engineering geological surface mapping, geotechnical drilling, in situ and laboratory testing and geophysical investigations. The above mentioned methods were combined for the site characterization in selected sites of the Hellenic Accelerometric Network (HAN) in the area of Crete Island. The combination of the geotechnical and geophysical methods in thirteen (13) sites provided sufficient information about their limitations, setting up the minimum tests requirements in relation to the type of the geological formations. The reduced accuracy of the surface mapping in urban sites, the uncertainties introduced by the geophysical survey in sites with complex geology and the 1-D data provided by the geotechnical drills are some of the causes affecting the right order and the quantity of the necessary investigation methods. Through this study the gradual improvement on the accuracy of the site characterization data in regards to the applied investigation techniques is presented by providing characteristic examples from the total number of thirteen sites. As an example of the gradual improvement of the knowledge about the ground conditions the case of AGN1 strong motion station, located at Agios Nikolaos city (Eastern Crete), is briefly presented. According to the medium scale geological map of IGME the station was supposed to be founded over limestone. The detailed geological mapping reveled that a few meters of loose alluvial deposits occupy the area, expected

  13. Nations within a nation: variations in epidemiological transition across the states of India, 1990-2016 in the Global Burden of Disease Study.

    18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016. Using all available data sources, the India State-Level Disease Burden Initiative estimated burden (metrics were deaths, disability-adjusted life-years [DALYs], prevalence, incidence, and life expectancy) from 333 disease conditions and injuries and 84 risk factors for each state of India from 1990 to 2016 as part of GBD 2016. We divided the states of India into four epidemiological transition level (ETL) groups on the basis of the ratio of DALYs from communicable, maternal, neonatal, and nutritional diseases (CMNNDs) to those from non-communicable diseases (NCDs) and injuries combined in 2016. We assessed variations in the burden of diseases and risk factors between ETL state groups and between states to inform a more specific health-system response in the states and for India as a whole. DALYs due to NCDs and injuries exceeded those due to CMNNDs in 2003 for India, but this transition had a range of 24 years for the four ETL state groups. The age-standardised DALY rate dropped by 36·2% in India from 1990 to 2016. The numbers of DALYs and DALY rates dropped substantially for most CMNNDs between 1990 and 2016 across all ETL groups, but rates of reduction for CMNNDs were slowest in the low ETL state group. By contrast, numbers of DALYs increased substantially for NCDs in all ETL state groups, and increased significantly for injuries in all ETL state groups except the highest. The all-age prevalence of most leading NCDs
