Military and law enforcement personnel may be routinely and repetitively exposed to low-level blast (LLB) overpressure during training and in operations. This repeated exposure has been associated with symptoms similar to that reported for sports concussion. This study reports LLB exposure for various military and law enforcement sources in operational training environments. Peak overpressure and impulse data are presented from indoor breaching, outdoor breaching, shotgun door breaching, small arms discharge, and mortar and artillery fire missions. Data were collected using the Black Box Biometrics (B3) Blast Gauge sensors. In all cases, sensors were attached to the operators and, where possible, also statically mounted to walls or other fixed structures. Peak overpressures from below 1 psi (7 kPa) to over 12 psi (83 kPa) were recorded; all values reported are uncorrected for incidence angle to the blast exposure source. The results of these studies indicate that the current minimum safe distance calculations are often inaccurate for both indoor and outdoor breaching scenarios as true environmental exposure can consistently exceed the 4 psi (28 kPa) incident safe threshold prescribed by U.S. Army doctrine. While ballistic (shotgun) door breaching and small arms firing only expose the operator to low peak exposure levels, the sheer number of rounds fired during training may result in an excessive cumulative exposure. Mortar and artillery crew members received significantly different overpressure and impulse exposures based on their position (job) relative to the weapon. As both the artillery and mortar crews commonly fire hundreds of rounds during a single training session they are also likely to receive high cumulative exposures. These studies serve to provide the research community with estimates for typical operator exposure across a range of operational scenarios or in the discharge of various weapons systems.

Sub-harmonic component generated from microbubbles is proven to be potentially used in noninvasive blood pressure measurement. Both theoretical and experimental studies are performed in the present work to investigate the dependence of the sub-harmonic generation on the overpressure with different excitation pressure amplitudes and pulse lengths. With 4-MHz ultrasound excitation at an applied acoustic pressure amplitude of 0.24 MPa, the measured sub-harmonic amplitude exhibits a decreasing change as overpressure increases; while non-monotonic change is observed for the applied acoustic pressures of 0.36 MPa and 0.48 MPa, and the peak position in the curve of the sub-harmonic response versus the overpressure shifts toward higher overpressure as the excitation pressure amplitude increases. Furthermore, the exciting pulse with long duration could lead to a better sensitivity of the sub-harmonic response to overpressure. The measured results are explained by the numerical simulations based on the Marmottant model. The numerical simulations qualitatively accord with the measured results. This work might provide a preliminary proof for the optimization of the noninvasive blood pressure measurement through using sub-harmonic generation from microbubbles.

Maximum overpressure in gastight containers of the storage and transport of dangerous liquids

International Nuclear Information System (INIS)

Steen, H.

1977-11-01

For a design of containers suitable under safety aspects for the transport and storage of dangerous liquids the maximum overpressure to be expected is an important value. The fundamentals for the determination of the internal pressure are pointed out for the simplified model of a rigid (i.e. not elastically or plastically deforming) and gastight container. By assuming of extreme storage and transport conditions (e.g. for the maximum liquid temperatures due to sun radiation) the figures of the maximum overpressure are calculated for about hundred liquids being of practical interest. The results show a significant influence of the compression of air in the ullage space caused by liquid expansion due to temperature rise (compression effect), particularly for liquids with a higher boiling point. The influence of the solubility of air in the liquid on the internal pressure can be neglected under the assumed transport conditions. The estimation of the volume increase of the container due to the effect of the internal pressure leads to the limitation, that the assumption of a rigid container is only justified for cylindrical and spherical steel tanks. The enlargement of the container volume due to a heating of the container shell does play no significant roll for all metal containers under the assumed conditions of storage and transport. The results obtained bear out essentially the stipulations for the test pressure and the filling limits laid down in the older German regulations for the transport of dangerous liquids in rail tank waggons and road tank vehicles without pressure relief valves. For the recently fixed and internationally harmonized regulations for tankcontainers the considerations and the results pointed out in this paper give rise to a review. (orig.) [de

Overpressure is an abnormal high subsurface pressure of any fluids which exceeds the hydrostatic pressure of column of water or formation brine. In Offshore Nova Scotia Canada, the values and depth of overpressure zone are determined using the eaton and equivalent depth method, based on well data and the normal compaction trend analysis. Since equivalent depth method is using effective vertical stress principle and Eaton method considers physical property ratio (velocity). In this research, pressure evaluation only applicable on Penobscot L-30 well. An abnormal pressure is detected at depth 11804 feet as possibly overpressure zone, based on pressure gradient curve and calculation between the Eaton method (7241.3 psi) and Equivalent Depth method (6619.4 psi). Shales within Abenaki formation especially Baccaro Member is estimated as possible overpressure zone due to hydrocarbon generation mechanism.

Coudert, C.; Amesz, J.; Volta, G.

1977-03-01

The problem of assessing the probability distribution of accidental transients in a nuclear plant is dealt with. The presented method consists of a combined probabilistic-deterministic approach. This approach is probabilistic in the sense that for each combination of system states a probability figure is determined by means of a fault-free analysis. It is deterministic in the sense that the corresponding sequence (e.g. magnitude of over-pressure) for each combination of states is computed by deterministic codes. An example is given in which the overpressure distribution of a pressurized water reactor is estimated

This paper presents and discusses trends in nose shock overpressure generated by two conceptual Mach 2.0 configurations. One configuration was designed for high aerodynamic efficiency, while the other was designed to produce a low boom, shaped-overpressure signature. Aerodynamic lift, sonic boom minimization, and Mach-sliced/area-rule codes were used to analyze and compute the sonic boom characteristics of both configurations with respect to cruise Mach number, weight, and altitude. The influence of these parameters on the overpressure and the overpressure trends are discussed and conclusions are given.

Analysis of the Explosive Internal Impact on the Barriers of Building Structures

Siwiński, Jarosław; Stolarski, Adam

2017-10-01

Work issues concern the safety of construction in relation to the hazards arising from explosion of the explosive charge located inside the building. The algorithms proposed in the paper for determining the parameters of the overpressure wave resulting from the detonation of clustered explosive charges, determine the basis for numerical simulation analyzes. Determination of the maximum value of peak pressure on the wave forehead of an internal explosion is presented on the basis of reflected wave analysis. Changeability in time of the internal explosion action describes the overpressure phase only. The analysis of the load caused by the internal explosive charge detonation was carried out under conditions of the undisturbed standard atmosphere. A load determination algorithm has been developed, taking into account the geometrical characteristics of the building barriers and the rooms as well as the parameters of environment in which the detonation occurs. The way of taking into account the influence of venting surfaces, i.e. windows, doors, ventilation ducts, on the overpressure wave parameters, was presented. Discloses a method to take into account the effect of the surface relief, i.e. windows, doors, air ducts, pressure wave parameters. Modification of the method for explosive overpressure determination presented by Cormie, Smith, Mays (2009), was proposed in the paper. This modification was developed on the basis of substitute impulse analysis for multiple overpressure pulses. In order to take into account the pressure distribution of explosive gases on the barrier surface, the method of modification the relationship for determination the changeability over time and space of the pressure of explosive gases, was presented. For this purpose, the changeability of the pressure wave angles of incidence to the barrier and the distance of the explosive charge to any point on the surface of the barrier, was taken into account. Based on the developed procedure, the

The accurate recording and analysis of air-blast acoustic waveforms is a key component of the forensic analysis of explosive events. Smartphone apps can enhance traditional technologies by providing scalable, cost-effective ubiquitous sensor solutions for monitoring blasts, undeclared activities, and inaccessible facilities. During a series of near-surface chemical high explosive tests, iPhone 6's running the RedVox infrasound recorder app were co-located with high-fidelity Hyperion overpressure sensors, allowing for direct comparison of the resolution and frequency content of the devices. Data from the traditional sensors is used to characterize blast signatures and to determine relative iPhone microphone amplitude and phase responses. A Wiener filter based source deconvolution method is applied, using a parameterized source function estimated from traditional overpressure sensor data, to estimate system responses. In addition, progress on a new parameterized air-blast model is presented. The model is based on the analysis of a large set of overpressure waveforms from several surface explosion test series. An appropriate functional form with parameters determined empirically from modern air-blast and acoustic data will allow for better parameterization of signals and the improved characterization of explosive sources.

Protection of the lung from blast overpressure by stress wave decouplers, buffer plates or sandwich panels.

Sedman, Andrew; Hepper, A

2018-03-19

This paper outlines aspects of UK Ministry of Defence's research and development of blast overpressure protection technologies appropriate for use in body armour, with the aim of both propagating new knowledge and updating existing information. Two simple models are introduced not only to focus the description of the mechanism by which the lungs can be protected, but also to provide a bridge between fields of research that may hold the key to further advances in protection technology and related body armour. Protection can be provided to the lungs by decoupling the stress wave transmission into the thorax by managing the blast energy imparted through the protection system. It is proposed that the utility of the existing 'simple decoupler' blast overpressure protection is reviewed in light of recent developments in the treatment of those sustaining both overpressure and fragment injuries. It is anticipated that further advances in protection technology may be generated by those working in other fields on the analogous technologies of 'buffer plates' and 'sandwich panels'. © Crown copyright (2018), Dstl.

Dynamic structural response of reactor-core subassemblies (hexcans) due to accident overpressurization

Pfeiffer, P.A.; Kulak, R.F.

1993-01-01

This paper presents a two-dimensional structural analysis for the evaluation of a single core subassembly due to internal overpressure associated with possible failure of fuel pins having high fission gas plenum pressure. Structural models are developed for the subassemblies and their surroundings with emphasis on the critical physical aspects of the problem. With these models the strains, deformations and the extent of permanent damage (plastic strain) to the subassemblies can be assessed. The nonlinear structural analyses was performed with a finite element program called STRAW (Structural Transient Response of Assembly Wrappers). This finite element program is applicable to nonlinear large displacement problems. The results of this study indicate that the permanent deformation (damage) is strongly influenced by the rise time (time to reach peak pressure) of the pressure pulse and the pressure in the fuel pin. The rise time is influenced by the opening time of the flow path for release of gas from the fuel pin plenum. Several examples are illustrated with various rise times and pressure magnitudes and the resulting permanent deformation of the hexcan wall. (author)

Simulation and Measurements of Small Arms Blast Wave Overpressure in the Process of Designing a Silencer

Directory of Open Access Journals (Sweden)

2015-02-01

Full Text Available Simulation and measurements of muzzle blast overpressure and its physical manifestations are studied in this paper. The use of a silencer can have a great influence on the overpressure intensity. A silencer is regarded as an acoustic transducer and a waveguide. Wave equations for an acoustic dotted source of directed effect are used for physical interpretation of overpressure as an acoustic phenomenon. Decomposition approach has proven to be suitable to describe the formation of the output wave of the wave transducer. Electroacoustic analogies are used for simulations. A measurement chain was used to compare the simulation results with the experimental ones.

Natural gas hydrate systems can be characterized by high sedimentation rates and/or low permeability sediments, which can lead to pore pressure higher than hydrostatic. This paper discussed a study that examined this effect of overpressure on gas hydrate and free gas distribution in marine sediments. A one-dimensional numerical model that coupled sedimentation, fluid flow, and gas hydrate formation was utilized. In order to quantify the relative importance of sedimentation rates and low permeability sediments, a dimensionless sedimentation-compaction group (scN) was defined, that compared the absolute permeability of the sediments to the sedimentation rate. Higher values of scN mean higher permeability or low sedimentation rate which generally yield hydrostatic pore pressure while lower values of scN normally create pore pressure greater than hydrostatic. The paper discussed non-hydrostatic consolidation in gas hydrate systems, including mass balances; constitutive relationships; normalized variables; and dimensionless groups. A numerical solution to the problem was presented. It was concluded that simulation results demonstrated that decreasing scN not only increased pore pressure above hydrostatic values, but also lowered the lithostatic stress gradient and gas hydrate saturation. This occurred because overpressure resulted in lower effective stress, causing higher porosity and lower bulk density of the sediment. 16 refs., 5 figs., 1 appendix.

Study on the quantitative rod internal pressure design criterion

Kim, Kyu Tae; Kim, Oh Hwan; Han, Hee Tak

1991-01-01

The current rod internal pressure criterion permits fuel rods to operate with internal pressures in excess of system pressure only if internal overpressure does not cause the diametral gap enlargement. In this study, the generic allowable internal gas pressure not violating this criterion is estimated as a function of rod power. The results show that the generic allowable internal gas pressure decreases linearly with the increase of rod power. Application of the generic allowable internal gas pressure for the rod internal pressure design criterion will result in the simplication of the current design procedure for checking the diametral gap enlargement caused by internal overpressure because according to the current design procedure the cladding creepout rate should be compared with the fuel swelling rate at each axial node at each time step whenever internal pressure exceeds the system pressure.

A new method for calculating gas content of coal reservoirs with consideration of a micro-pore overpressure environment

Directory of Open Access Journals (Sweden)

Jinxing Song

2017-05-01

Full Text Available When the gas content of a coal reservoir is calculated, the reservoir pressure measured by well logging and well testing is generally used for inversion calculation instead of gas pressure. However, the calculation result is not accurate because the reservoir pressure is not equal to the gas pressure in overpressure environments. In this paper, coal samples of different ranks in Shanxi and Henan are collected for testing the capillary pressure of coal pores. Based on the formation process of CBM reservoirs and the hydrocarbon generation and expulsion history of coal beds, the forming mechanisms of micro-pore overpressure environments in coal reservoirs were analyzed. Accordingly, a new method for calculating the gas content of coal reservoirs with consideration of a micro-pore overpressure environment was developed. And it was used to calculate the gas content of No. 1 coal bed of the 2nd member of Lower Permian Shanxi Fm in the Zhongmacun Coal Mine in Jiaozuo, Henan. It is indicated that during the formation and evolution of coals, some solid organic matters were converted into gas and water, and gas–water contact is surely formed in pores. In the end, capillary pressure is generated, so the gas pressure in micro-pores is much higher than the hydrostatic column pressure, which results in a micro-pore overpressure environment. Under such an environment, gas pressure is higher than reservoir pressure, so the gas content of coal reservoirs calculated previously based on the conventional reservoir pressure evaluation are usually underestimated. It is also found that the micro-pore overpressure environment exerts a dominating effect on the CBM content calculation of 3–100 nm pores, especially that of 3–10 nm pores, but a little effect on that of pores >100 nm. In conclusion, this new method clarifies the pressure environment of CBM gas reservoirs, thereby ensuring the calculation accuracy of gas content of coal reservoirs.

Nankai Stress History and Implications for an Overpressured Decollement

Science.gov (United States)

Moran, K.; O'Regan, M.

2005-12-01

The Nankai Trough, formed from the subduction of the Shikoku Basin beneath the island arc of southwestern Japan, is a relatively young accretionary complex converging at a rate of ~4 cm/yr [Shipboard Scientific Party, 2001a]. The region was studied during the Deep Sea Drilling Project and on three Ocean Drilling Program (ODP) Legs-131, 190 and 196. Three sites visited during these Legs form a single cross-margin transect (dubbed the Muroto Transect) that traverses the leading edge of the Nankai accretionary prism, from seaward of the deformation front at Site 1173, to close to the deformation front (Site 1174), and landward to the first frontal thrust (Site 808). The decollement, which forms the major boundary between the converging plates, occurs within the Lower Shikoku Basin stratigraphic unit. The ODP sites were drilled and cored to depths below the decollement (Sites 808 and 1174) and the proto-decollement (Site 1173). Here we present consolidation test results [Moran et al., 1993] that are consistent with porosity-depth functions from core and log measurements for the Lower Shikoku Basin sediments, assuming that the decollement is an overpressured seal. At 1173, where a true decollement has not yet formed, moderate fluid overpressures occur that can be fully attributed to high turbiditic sedimentation rates. Forward modeling of this site into the deformation front over a period of ~300 ky shows that the present 1173 porosity-depth function matches the porosity-depth function at 1174. These results suggest that the young decollement on the Muroto Transect at the deformation front and landward is highly overpressured and forms a seal to sediments below that can be classically modeled as a one-dimensional consolidation system.

Structural response of reactor-core hexcan subassemblies subjected to dynamic overpressurization under accident conditions

This paper presents a two-dimensional structural analysis for the evaluation of a single core subassembly due to internal overpressure associated with possible failure of fuel pins having high fission gas plenum pressure. Structural models are developed for the subassemblies and their surroundings with emphasis on the critical physical aspects of the problem. With these models the strains, deformations and the extent of permanent damage (plastic strain) to the subassemblies can be assessed. The nonlinear structural analyses was performed with a finite element program called STRAW (Structural Transient Response of Assembly Wrappers). This finite element program is applicable to nonlinear large displacement problems. The results of this study indicate that the permanent deformation (damage) is strongly influenced by the rise time (time to reach peak pressure) of the pressure pulse and the pressure in the fuel pin. The rise time is influenced by the opening time of the flow path for release of gas from the fuel pin plenum. Several examples are illustrated with various rise times and pressure magnitudes and the resulting permanent deformation of the hexcan wall

Characterization of the Scale Model Acoustic Test Overpressure Environment using Computational Fluid Dynamics

Science.gov (United States)

Nielsen, Tanner; West, Jeff

2015-01-01

The Scale Model Acoustic Test (SMAT) is a 5% scale test of the Space Launch System (SLS), which is currently being designed at Marshall Space Flight Center (MSFC). The purpose of this test is to characterize and understand a variety of acoustic phenomena that occur during the early portions of lift off, one being the overpressure environment that develops shortly after booster ignition. The pressure waves that propagate from the mobile launcher (ML) exhaust hole are defined as the ignition overpressure (IOP), while the portion of the pressure waves that exit the duct or trench are the duct overpressure (DOP). Distinguishing the IOP and DOP in scale model test data has been difficult in past experiences and in early SMAT results, due to the effects of scaling the geometry. The speed of sound of the air and combustion gas constituents is not scaled, and therefore the SMAT pressure waves propagate at approximately the same speed as occurs in full scale. However, the SMAT geometry is twenty times smaller, allowing the pressure waves to move down the exhaust hole, through the trench and duct, and impact the vehicle model much faster than occurs at full scale. The DOP waves impact portions of the vehicle at the same time as the IOP waves, making it difficult to distinguish the different waves and fully understand the data. To better understand the SMAT data, a computational fluid dynamics (CFD) analysis was performed with a fictitious geometry that isolates the IOP and DOP. The upper and lower portions of the domain were segregated to accomplish the isolation in such a way that the flow physics were not significantly altered. The Loci/CHEM CFD software program was used to perform this analysis.

Insulation vacuum and beam vacuum overpressure release

CERN Document Server

Parma, V

2009-01-01

There is evidence that the incident of 19th September caused a high pressure build-up inside the cryostat insulation vacuum which the existing overpressure devices could not contain. As a result, high longitudinal forces acting on the insulation vacuum barriers developed and broke the floor and the floor fixations of the SSS with vacuum barriers. The consequent large longitudinal displacements of the SSS damaged chains of adjacent dipole cryo-magnets. Estimates of the helium mass flow and the pressure build- up experienced in the incident are presented together with the pressure build-up for an even more hazardous event, the Maximum Credible Incident (MCI). The strategy of limiting the maximum pressure by the installation of addition pressure relieve devices is presented and discussed. Both beam vacuum lines were ruptured during the incident in sector 3-4 giving rise to both mechanical damage and pollution of the system. The sequence, causes and effects of this damage will be briefly reviewed. We will then an...

CFD Assessment of Forward Booster Separation Motor Ignition Overpressure on ET XT 718 Ice/Frost Ramp

Tejnil, Edward; Rogers, Stuart E.

2012-01-01

Computational fluid dynamics assessment of the forward booster separation motor ignition over-pressure was performed on the space shuttle external tank X(sub T) 718 ice/frost ramp using the flow solver OVERFLOW. The main objective of this study was the investigation of the over-pressure during solid rocket booster separation and its affect on the local pressure and air-load environments. Delta pressure and plume impingement were investigated as a possible contributing factor to the cause of the debris loss on shuttle missions STS-125 and STS-127. A simplified computational model of the Space Shuttle Launch Vehicle was developed consisting of just the external tank and the solid rocket boosters with separation motor nozzles and plumes. The simplified model was validated by comparison to full fidelity computational model of the Space Shuttle without the separation motors. Quasi steady-state plume solutions were used to calibrate the thrust of the separation motors. Time-accurate simulations of the firing of the booster-separation motors were performed. Parametric studies of the time-step size and the number of sub-iterations were used to find the best converged solution. The computed solutions were compared to previous OVERFLOW steady-state runs of the separation motors with reaction control system jets and to ground test data. The results indicated that delta pressure from the overpressure was small and within design limits, and thus was unlikely to have contributed to the foam losses.

Current state of knowledge on the behavior of steel liners in concrete containments subjected to overpressurization loads

International Nuclear Information System (INIS)

Riesemann, W.A. von; Parks, M.B.

1995-01-01

In the US, concrete containment buildings for commercial nuclear power plants have steel liners that act as the internal pressure boundary. The liner abuts the concrete, acting as the interior concrete form. The liner is attached to the concrete by either studs or by a continuous structural shape (such as a T-section or channel) that is either continuously or intermittently welded to the liner. Studs are commonly used in reinforced concrete containments, while prestressed containments utilize a structural element as the anchorage. The practice in some countries follows the US practice, while in other countries the containment does not have a steel liner. In this latter case, there is a true double containment, and the annular region between the two containments is vented.This paper will review the practice of design of the liner system prior to the consideration of severe accident loads (overpressurization loads beyond the design conditions).An overpressurization test of a 1:6 scale reinforced concrete containment at Sandia National Laboratories resulted in a failure mechanism in the liner that was not fully anticipated. Post-test analyses and experiments have been conducted to understand the failure better. This work and the activities that followed the test are reviewed. Areas in which additional research should be conducted are given. (orig.)

Overpressure, Flow Focusing, Compaction and Slope Stability on the continental slope: Insights from IODP Expedition 308

Integrated Ocean Drilling Program Expepedition 308 used direct measurements of pore pressure, analysis of hydromechanical properties, and geological analysis to illuminate how sedimentation, flow focusing, overpressure, and slope stability couple beneath the seafloor on the deepwater continental slope in the Gulf of Mexico. We used pore pressure penetrometers to measure severe overpressures (60% of the difference between lithostatic stress and hydrostatic pressure) that extend from the seafloor for 100’s of meters. We ran uniaxial consolidation experiments on whole core and found that although permeability is relatively high near the seafloor, the sediments are highly compressible. As a result, the coefficient of consolidation (the hydraulic diffusivity) is remarkably constant over a large range of effective stresses. This behavior accounts for the high overpressure that begins near the seafloor and extends to depth. Forward modeling suggests that flow is driven laterally along a permeable unit called the Blue Unit. Calculations suggest that soon after deposition, lateral flow lowered the effective stress and triggered the submarine landslides that we observe. Later in the evolution of this system, overpressure may have pre-conditioned the slope to failure by earthquakes. Results from IODP Expedition 308 illustrate how pore pressure and sedimentation control the large-scale form of continental margins, how submarine landslides form, and provide strategies for designing stable drilling programs.

Paper presents the methodology of laboratory tests for ventilation overpressure differential systems for smoke protection of lobbies. Research area consists of two spaces representing the lobby and the area under fire equipped with proper ventilation installation. This allows testing of overpressure differential systems for smoke protection of lobbies. Moreover, piece of laboratory tests results for two selected smoke protection systems for lobbies are presented. First one is standard system with constantly opened transfer-damper mounted between lobby and area under fire. Second one - system with so called "electronic transfer" based on two dampers (supplying air to a lobby and to unprotected area alternatively). Opening and closing both dampers is electronically controlled. Changes of pressure difference between lobby and fire affected area during closing and opening doors between those spaces is presented. Conclusions, concerning the possibility of meeting the time period criteria of pressure difference stabilization required by standards, are presented and discussed for both systems.

Full Text Available Taking the Well JY1 and Well PY1 in the Eastern Sichuan Basin as examples, the formation mechanism of shale gas overpressure was studied by using the cross plot of acoustic versus density logging data. During the processes of hydrocarbon generation and the uplifting, the pressure evolution of fluids in shale gas layers was reconstructed by fluid inclusions and PVTSIM software. The major factors controlling the evolution of shale gas overpressure were established according to the study of fracture, the timing of the uplifting, and episodes of tectonic deformation. Our results showed that the main mechanism of overpressure in the Silurian shale gas reservoirs in the Sichuan Basin was the fluid expansion, which was caused by hydrocarbon generation. Since the Yanshanian, the strata were uplifted and fluid pressure generally showed a decreasing trend. However, due to the low compression rebound ratio of shale gas reservoir rocks, poor connectivity of reservoir rocks, and low content of formation water and so on, such factors made fluid pressure decrease, but these would not be enough to make up the effects of strata erosion resulting in a further increase in fluid pressure in shale gas reservoirs during the whole uplifting processes. Since the Yanshanian, the Well PY1 zone had been reconstructed by at least three episodes of tectonic movement. The initial timing of the uplifting is 130 Ma. Compared to the former, the Well JY1 zone was firstly uplifted at 90 Ma, which was weakly reconstructed. As a result, low-angle fractures and few high resistance fractures developed in the Well JY1, while high-angle fractures and many high resistance fractures developed in the Well PY1. In totality, the factors controlling the overpressure preservation in shale gas reservoirs during the late periods include timing of late uplifting, superposition and reconstruction of stress fields, and development of high-angle fractures.

Overpressure is one important cause of domino effect in accidents of chemical process equipments. Some models considering propagation probability and threshold values of the domino effect caused by overpressure have been proposed in previous study. In order to prove the rationality and validity of the models reported in the reference, two boundary values of three damage degrees reported were considered as random variables respectively in the interval [0, 100%]. Based on the overpressure data for damage to the equipment and the damage state, and the calculation method reported in the references, the mean square errors of the four categories of damage probability models of overpressure were calculated with random boundary values, and then a relationship of mean square error vs. the two boundary value was obtained, the minimum of mean square error was obtained, compared with the result of the present work, mean square error decreases by about 3%. Therefore, the error was in the acceptable range of engineering applications, the models reported can be considered reasonable and valid.

Basic, I.; Krajnc, B.; Bajs, T.

2000-01-01

NEK has expressed interest in the acceptability of removing the autoclosure interlock (ACI) on the Residual Heat Removal System (RHRS) suction/isolation valves. This interest is in response to growing concerns about the loss of residual heat removal capability during cold shutdown and refueling operations. This article describes effort done to justify removal of the ACI in the light of low temperature overpressure protection of Reactor Coolant System (RCS) and RHRS and interfacing system LOCA potential. The intent of this article is to review the NEK RHRS relief valves sizing design basis and verify if the relief valves provide RHRS overpressure protection for the events possible at cold shutdown. Inadvertent isolation of RHRS during hot and cold shutdown (with reactor coolant system closed and temperatures below 177o Code 4 and5) presents one of the major safety concerns in this mode of operation. Detailed RELAP5 model of NPP Kriko following steam generator (SG) replacement and core uprate has been used in the frame of this analysis verification of RHRS relief valves sizing. The following limiting cases for cold shutdown with RCS solid conditions have been analyzed: - ransients that affect the system input/output mass balance, - ransients that affect the heat input/removal balance.

Full Text Available The energy efficiency improvement of the city housing-and-utilities infrastructure and watersupply and water-disposal systems poses an occurrent problem. The water-supply systems energy consumption sizable share falls on the pump plants. The article deals with the issues of the operating regime management of the existing booster stations equipped with a group of pumping units regulated with frequency converters. One of the optimization directions of their energy consumption is the reduction of over-pressure in the water-distribution network and its sustentation within the regulatory values. The authors offer the structure and methodology of the data collection-and-analysis automated system utilization for revealing and eliminating the overpressure in the water-supply network. This system is designed for the group management of booster-stations operating regimes on the ground of data obtained from the pressure controlling devices at the consumers. The data exchange in the system is realized via GSM.The paper presents results of the tests carried out at the booster stations in some major cities of the Republic of Belarus. The authors analyze dependence of overpressure in the network on the methods of the plant output pressure sustentation (daily graph or constant pressure. The authors study the elimination effect of over-pressure in the water distribution network on changing the booster station pumping units operation regimes. The study shows that eliminating over pressure in the water distributing network leads to lowering the booster station pressure. This in its turn decreases its energy consumption by 15–20 % depending on the over pressure fixed level.

Bhabha Atomic Research Centre (BARC), Trombay has organized an International Round Robin Analysis program to carry out the ultimate load capacity assessment of BARC Containment (BARCOM) test model. The test model located in BARC facilities Tarapur; is a 1:4 scale representation of 540 MWe Pressurized Heavy Water Reactor (PHWR) pre-stressed concrete inner containment structure of Tarapur Atomic Power Station (TAPS) unit 3 and 4. There are a large number of sensors installed in BARCOM that include vibratory wire strain gauges of embedded and spot-welded type, surface mounted electrical resistance strain gauges, dial gauges, earth pressure cells, tilt meters and high resolution digital camera systems for structural response, crack monitoring and fracture parameter measurement to evaluate the local and global behavior of the containment test model. The model has been tested pneumatically during the low pressure tests (LPTs) followed by proof test (PT) and integrated leakage rate test (ILRT) during commissioning. Further the over pressure test (OPT) has been carried out to establish the failure mode of BARCOM Test-Model. The over-pressure test will be completed shortly to reach the functional failure of the test model. Pre-test evaluation of BARCOM was carried out with the results obtained from the registered international round robin participants in January 2009 followed by the post-test assessment in February 2011. The test results along with the various failure modes related to the structural members – concrete, rebars and tendons identified in terms of prescribed milestones are presented in this paper along with the comparison of the pre-test predictions submitted by the registered participants of the Round Robin Analysis for BARCOM test model.

Construction of a school in Fairfax County, Virginia, is being carefully monitored since elevated indoor radon levels have been identified in many existing houses near the site. Soil gas radon concentrations measured prior to pouring of the slabs were also indicative of a potential radon problem should the soil gas enter the school; however, subslab radon measurements collected thus far are lower than anticipated. Radon-resistant features have been incorporated into construction of the school and include the placing of at least 100 mm of clean coarse aggregate under the slab and a plastic film barrier between the aggregate and the slab, the sealing of all expansion joints, the sealing or plugging of all utility penetrations where possible, and the painting of interior block walls. In addition, the school's heating, ventilating, and air-conditioning (HVAC) system has been designed to operate continuously in overpressurization to help reduce pressure-driven entry of radon-containing soil gas into the building. Following completion, indoor radon levels in the school will be monitored to determine the effectiveness of these radon-resistant new-construction techniques and HVAC overpressurization in limiting radon entry into the school

Explosion quantities and flashing mass resulting from the variation of temperature are calculated by a computer program, BLEVE ESTIMATOR, to carry out the risk assessment of BLEVE. The damages caused by the BLEVE are estimated under the explosion of the simulation condition similar to the Puchun LP gas station accident, and the results are compared with the commercial program SAFER of Dupont Co. Explosion quantities and flashing mass increase exponentially with the increase of explosion temperature. These values for propane are relatively higher than those for n-butane. In conditions of higher vessel temperature, vessel pressure, and liquid ratio of containment, higher overpressures are calculated. 10 refs., 12 figs., 2 tabs.

Air overpressure (AOp) resulting from blasting can cause damage and nuisance to nearby civilians. Thus, it is important to be able to predict AOp accurately. In this study, 8 different Artificial Neural Network (ANN) were developed for the purpose of prediction of AOp. The ANN models were trained using different variants of Particle Swarm Optimization (PSO) algorithm. AOp predictions were also made using an empirical equation, as suggested by United States Bureau of Mines (USBM), to serve as a benchmark. In order to develop the models, 76 blasting operations in Hulu Langat were investigated. All the ANN models were found to outperform the USBM equation in three performance metrics; root mean square error (RMSE), mean absolute percentage error (MAPE) and coefficient of determination (R2). Using a performance ranking method, MSO-Rand-Mut was determined to be the best prediction model for AOp with a performance metric of RMSE=2.18, MAPE=1.73% and R2=0.97. The result shows that ANN models trained using PSO are capable of predicting AOp with great accuracy.

A number of aspects of the Canadian concept for nuclear fuel waste disposal are being assessed by Atomic Energy of Canada Limited (AECL) in a series of experiments at its Underground Research Laboratory (URL) near Lac du Bonnet, Manitoba, Canada. One of the major objectives of the work being carried out at the URL is to develop and evaluate the methods and technology to ensure safe, permanent disposal of Canada's nuclear fuel waste. In 1994, AECL excavated access tunnels and a laboratory room for the Quarried Block Fracture Migration Experiment (QBFME) at the 240 Level of the URL. This facility will be used to study the transport of radionuclides in natural fractures in quarried blocks of granite under in-situ groundwater conditions. The experiment is being carried out under a cooperative agreement with the Japan Atomic Energy Research Institute. The excavation of the QBFME access tunnels and laboratory was carried out using controlled blasting techniques that minimized blast-induced overpressure which could have damaged or interrupted other ongoing experiments in the vicinity. The majority of the blasts used conventional long delay non-electric detonators but a number of blasts were carried out using HANDIDET 250/6000 non-electric long delay detonator assemblies and HTD reg-sign non-electric short delay trunkline detonator assemblies. The tunnel and laboratory excavation was monitored to determine the levels of blast-induced overpressure. This paper describes the blasting and monitoring results of the blasts using HANDIDET non-electric detonator assemblies and the effectiveness of these detonators in reducing blast-induced overpressure

Passive safety systems which are operated without power source are suggested as a solution SBO. For containment protection system, Containment Filtered Venting System (CFVS) is suggested. CFVS controls the containment pressure by releasing the containment gas through filter passively without any power source. But because still small amount of radioactive material have no choice but to release to the environment, starting time and operation method of CFVS have to be determined carefully. Later starting time brings not only lower release but also higher risk from containment failure by over-pressurization, so it is a problem. In this research, the effect of risk from containment failure by over-pressurization during the operation of containment filtered venting system was analyzed. In this research, optimized values for variables of the CFVS operation method are found as 0.67 MPa, 9 cm, 0.1 MPa each for open pressure, pressure interval, and vent pipe diameter when DF as a function of time and risk from containment over-pressurization failure are considered. Generally in this research, release without risk get lower values in higher pressure, and lower vent pipe diameter. Release with risk get sharply high values when the containment pressure exceeds the design pressure because of the effect of risk from containment failure by over-pressurization. In conclusion, highest pressure, and lowest vent pipe diameter which are not influenced by risk is the optimized values for CFVS operation method because amount of risk is much larger than release through the CFVS

The Atomic Energy Control Board of Canada initiated June, 1975, a major study of the behaviour of concrete containment under over-pressure conditions. Although extensive theoretical and experimental work has been carried out for thick-walled Prestressed Concrete Reactor Vessels (PCRV's), there is a want of information on the non-linear response of thin-walled structures typical of the CANDU, 600 MW(e) cylindrical/spherical, post-tensioned containment shells. The purpose of this paper is to provide an overview of the total program, to present the reasons behind the research contract, and the specification and implementation of the work. The results of the theoretical and experimental work and their implications with respect to Canadian Concrete Containment practice are discussed. This study is unique, and, as far as is known, has no world-wide precedence. (orig.)

2013-12-01

Fatal blast injuries are generally reported in literature as a consequence of the detonation of explosives in war settings. The pattern of lesion depends on the position of the victim in relation to the explosion, on whether the blast tracks through air or water, and whether it happens in the open air or within an enclosed space and the distance from the explosion. Tire explosion-related injuries are rarely reported in literature. This study presents a fatal case of blast overpressure due to the accidental explosion of a truck tire occurring in a tire repair shop. A multidisciplinary approach to the fatality involving forensic pathologists and engineers revealed that the accidental explosion, which caused a series of primary and tertiary blast wave injuries, was due to tire deterioration.

Mechanical study of the Chartreuse Fold-and-Thrust Belt: relationships between fluids overpressure and decollement within the Toarcian source-rock

Science.gov (United States)

Berthelon, Josselin; Sassi, William; Burov, Evgueni

2016-04-01

Many source-rocks are shale and constitute potential detachment levels in Fold-and-Thrust Belts (FTB): the toarcian Schistes-Cartons in the French Chartreuse FTB for example. Their mechanical properties can change during their burial and thermal maturation, as for example when large amount of hydrocarbon fluids are generated. A structural reconstruction of the Chartreuse FTB geo-history places the Toarcian Formation as the major decollement horizon. In this work, a mechanical analysis integrating the fluids overpressuring development is proposed to discuss on the validity of the structural interpretation. At first, an analogue of the Chartreuse Toarcian Fm, the albanian Posidonia Schist, is documented as it can provide insights on its initial properties and composition of its kerogen content. Laboratory characterisation documents the vertical evolution of the mineralogical, geochemical and mechanical parameters of this potential decollement layer. These physical parameters (i.e. Total Organic Carbon (TOC), porosity/permeability relationship, friction coefficient) are used to address overpressure buildup in the frontal part of the Chartreuse FTB with TEMISFlow Arctem Basin modelling approach (Faille et al, 2014) and the structural emplacement of the Chartreuse thrust units using the FLAMAR thermo-mechanical model (Burov et al, 2014). The hydro-mechanical modeling results highlight the calendar, distribution and magnitude of the overpressure that developed within the source-rock in the footwall of a simple fault-bend fold structure localized in the frontal part of the Chartreuse FTB. Several key geological conditions are required to create an overpressure able to fracture the shale-rocks and induce a significant change in the rheological behaviour: high TOC, low permeability, favourable structural evolution. These models highlight the importance of modeling the impact of a diffuse natural hydraulic fracturing to explain fluids propagation toward the foreland within

Overpressure is one important cause of domino effect in accidents of chemical process equipments. Damage probability and relative threshold value are two necessary parameters in QRA of this phenomenon. Some simple models had been proposed based on scarce data or oversimplified assumption. Hence, more data about damage to chemical process equipments were gathered and analyzed, a quantitative relationship between damage probability and damage degrees of equipment was built, and reliable probit models were developed associated to specific category of chemical process equipments. Finally, the improvements of present models were evidenced through comparison with other models in literatures, taking into account such parameters: consistency between models and data, depth of quantitativeness in QRA.

Full Text Available In order to understand the geological and hydrogeological processes influencing the hydrogeochemical behavior of the Cerro Prieto Geothermal Field (CP aquifer, Mexico, a characterization of the water samples collected from geothermal wells was carried out. Different hydrochemical diagrams were used to evaluate brine evolution of the aquifer. To determine pressure conditions at depth, a calculation was performed using hydrostatic and lithostatic properties from CP, considering geological characteristics of the study area, and theoretical information about some basin environments. Groundwater shows hydrogeochemical and geological evidences of the diagenetic evolution that indicate overpressure conditions. Some physical, chemical, textural, and mineralogical properties reported in the lithological column from CP are explained understanding the evolutionary process of the sedimentary material that composes the aquifer.

Design and fabrication of a 30 T superconducting solenoid using overpressure processed Bi2212 round wire

High field superconducting magnets are used in particle colliders, fusion energy devices, and spectrometers for medical imaging and advanced materials research. Magnets capable of generating fields of 20-30 T are needed by future accelerator facilities. A 20-30 T magnet will require the use of high-temperature superconductors (HTS) and therefore the challenges of high field HTS magnet development need to be addressed. Superconducting Bi₂Sr₂CaCu₂O_x (Bi2212) conductors fabricated by the oxide-powder-in-tube (OPIT) technique have demonstrated the capability to carry large critical current density of 10⁵ A/cm² at 4.2 K and in magnetic fields up to 45 T. Available in round wire multi-filamentary form, Bi2212 may allow fabrication of 20-50 T superconducting magnets. Until recently the performance of Bi2212 has been limited by challenges in realizing high current densities (J_c ) in long lengths. This problem now is solved by the National High Magnetic Field Lab using an overpressure (OP) processing technique, which uses external pressure to process the conductor. OP processing also helps remove the ceramic leakage that results when Bi-2212 liquid leaks out from the sheath material and reacts with insulation, coil forms, and flanges. Significant advances have also been achieved in developing novel insulation materials (TiO₂ coating) and Ag-Al sheath materials that have higher mechanical strengths than Ag-0.2wt.% Mg, developing heat treatment approaches to broadening the maximum process temperature window, and developing high-strength, mechanical reinforced Bi-2212 cables. In the Phase I work, we leveraged these new opportunities to prototype overpressure processed solenoids and test them in background fields of up to 14 T. Additionally a design of a fully superconducting 30 T solenoid was produced. This work in conjunction with the future path outlined in the Phase II proposal would

Research on the water hammer protection of the long distance water supply project with the combined action of the air vessel and over-pressure relief valve

We take a concrete pumping station as an example in this paper. Through the calculation of water hammer protection with a specific pumping station water supply project, and the analysis of the principle, mathematical models and boundary conditions of air vessel and over-pressure relief valve we show that the air vessel can protect the water conveyance system and reduce the transient pressure damage due to various causes. Over-pressure relief valve can effectively reduce the water hammer because the water column re-bridge suddenly stops the pump and prevents pipeline burst. The paper indicates that the combination set of air vessel and over-pressure relief valve can greatly reduce the quantity of the air valve and can eliminate the water hammer phenomenon in the pipeline system due to the vaporization and water column separation and re-bridge. The conclusion could provide a reference for the water hammer protection of long-distance water supply system

Acoustic investigation of the aperture dynamics of an elastic membrane closing an overpressurized cylindrical cavity

Science.gov (United States)

Sánchez, Claudia; Vidal, Valérie; Melo, Francisco

2015-08-01

We report an experimental study of the acoustic signal produced by the rupture of an elastic membrane that initially closes a cylindrical overpressurized cavity. This configuration has been recently used as an experimental model system for the investigation of the acoustic emission from the bursting of elongated gas bubbles rising in a conduit. Here, we investigate the effect of the membrane rupture dynamics on the acoustic signal produced by the pressure release by changing the initial tension of the membrane. The initial overpressure in the cavity is fixed at a value such that the system remains in the linear acoustic regime. For large initial membrane deformation, the rupture time τ rup is small compared to the wave propagation time in the cavity and the pressure wave inside the conduit can be fully captured by the linear theory. For low membrane tension, a hole is pierced in the membrane but its rupture does not occur. For intermediate deformation, finally, the rupture progresses in two steps: first the membrane opens slowly; then, after reaching a critical size, the rupture accelerates. A transversal wave is excited along the membrane surface. The characteristic signature of each opening dynamics on the acoustic emission is described.

Overpressures: Causal Mechanisms, Conventional and Hydromechanical Approaches Surpressions : origine, approches conventionnelle et hydromécanique

Full Text Available Abnormal fluid pressure regimes are commonly encountered at depth in most sedimentary basins. Relationships between effective vertical stress and porosity have been applied, since 1970 to the Gulf Coast area, to assess the magnitude of overpressures. Positive results have been obtained from seismic and basin-modeling techniques in sand-shale, vertical-stress-dominated tertiary basins, whenever compaction disequilibrium conditions apply. However, overpressures resulting from other and/or additional causes (tectonic stress, hydrocarbon generation, thermal stress, fault-related transfer, hydrofracturing. . . cannot be quantitatively assessed using this approach. A hydromechanical approach is then proposed in addition to conventional methods. At any depth, the upper bound fluid pressure is controlled by in situ conditions related to hydrofracturing or fault reactivation. Fluid-driven fracturing implies an episodically open system, under a close to zerominimum effective stress regime. Sound knowledge of present-day tectonic stress regimes allows a direct estimation of minimum stress evolution. A quantitative fluid pressure assessment at depth is therefore possible, as in undrained or/and compartmented geological systems, pressure regimes, whatever their origin, tend to rapidly reach a value close to the minimum principal stress. Therefore, overpressure assessment will be improved, as this methodology can be applied to various geological settings and situations where present-day overpressures originated from other causal mechanisms, very often combined. However, pressure trends in transition zones are more difficult to assess correctly. Additional research on cap rocks and fault seals is therefore required to improve their predictability. In addition to overpressure assessment, the minimum principal stress concept allows a better understanding of petroleum system, as fault-related hydrocarbon dynamic transfers, hydrofractured domains and cap

Interpretation of sonic log data of anticlinal structures from eastern Bangladesh reveals significant variations of acoustic velocity of subsurface strata. The amount of variation in velocity is 32% from Miocene to Pliocene stratigraphic units in Titas and Bakhrabad structure, whereas 21% in Rashidpur structure. Velocity fluctuations are influenced by the presence of gas-bearing horizons, with velocities of gas-producing strata 3-7% lower than laterally equivalent strata at similar depth. Average velocities of Miocene Boka Bil and Bhuban formations are, respectively, 2630 and 3480 m/s at Titas structure; 2820 and 3750 m/s at Bakhrabad; and 3430 and 3843 m/s at the Rashidpur structure. From the overall velocity-depth distribution for a common depth range of 915-3000 m, the Titas, Bakhrabad and Rashidpur structures show a gradual increase in velocity with depth. In contrast, the Sitakund anticline in SE Bangladesh reveals a decrease in velocity with depth from 3000 to 4000 m, probably due to the presence of overpressured mudrocks of the Bhuban Formation. Tectonic compression, associated with the Indo-Burmese plate convergence likely contributed the most toward formation of subsurface overpressure in the Sitakund structure situated in the Chittagong-Tripura Fold Belt of the eastern Bengal basin, Bangladesh.

A baffle-former arrangement for the reactor vessel internals of a nuclear reactor is described. The arrangement includes positioning of formers at the same elevations as the fuel assembly grids, and positioning flow holes in the baffle plates directly beneath selected former grid elevations. The arrangement reduces detrimental cross flows, maintains proper core barrel and baffle temperatures, and alleviates the potential of overpressurization within the baffle-former assembly under assumed major accident conditions

Linear and nonlinear propagation of high amplitude acoustic pulses through a turbulent layer in air is investigated using a two-dimensional KZK-type (Khokhlov-Zabolotskaya-Kuznetsov) equation. Initial waves are symmetrical N-waves with shock fronts of finite width. A modified von Kármán spectrum model is used to generate random wind velocity fluctuations associated with the turbulence. Physical parameters in simulations correspond to previous laboratory scale experiments where N-waves with 1.4 cm wavelength propagated through a turbulence layer with the outer scale of about 16 cm. Mean value and standard deviation of peak overpressure and shock steepness, as well as cumulative probabilities to observe amplified peak overpressure and shock steepness, are analyzed. Nonlinear propagation effects are shown to enhance pressure level in random foci for moderate initial amplitudes of N-waves thus increasing the probability to observe highly peaked waveforms. Saturation of the pressure level is observed for stronger nonlinear effects. It is shown that in the linear propagation regime, the turbulence mainly leads to the smearing of shock fronts, thus decreasing the probability to observe high values of steepness, whereas nonlinear effects dramatically increase the probability to observe steep shocks.

Full Text Available The throttling of liquefied substances from high pressure vessels to an enclosed volume starting at atmospheric pressure is described in order to determine thermodynamic state of the extinguished room gaseous contents. Time dependent, 0D mathematical model is implemented describing the state inside the agent container, the isenthalpic throttling in the distribution system, agent vaporization and mixing with air. The agent is modelled as real gas. Other influences on the process including the heat transfer from selected solid parts inside the room and the gas mixture leakage out of the room are taken into account. Main outcome is an MS Excel tool for integrated fire extinguishers design optimization. The optimization balances the two contradictory requirements: Agent volumetric concentration to sustain the fire extinguishing capabilities and tolerable room overpressure. Agent fill weight and discharge time are being adjusted. The discharge time is controlled by the distribution piping and spray nozzles design. System operation is checked concerning various initial and boundary conditions.

It is unclear whether combat eyewear used by U. S. Service members is protective against blast overpressures (BOPs) caused by explosive devices. Here, we investigated the mechanisms by which BOP bypasses eyewear and increases eye surface pressure. We performed experiments and developed three-dimensional (3D) finite element (FE) models of a head form (HF) equipped with an advanced combat helmet (ACH) and with no eyewear, spectacles, or goggles in a shock tube at three BOPs and five head orientations relative to the blast wave. Overall, we observed good agreement between experimental and computational results, with average discrepancies in impulse and peak-pressure values of less than 15% over 90 comparisons. In the absence of eyewear and depending on the head orientation, we identified three mechanisms that contributed to pressure loading on the eyes. Eyewear was most effective at 0 deg orientation, with pressure attenuation ranging from 50 (spectacles) to 80% (goggles) of the peak pressures observed in the no-eyewear configuration. Spectacles and goggles were considerably less effective when we rotated the HF in the counter-clockwise direction around the superior-inferior axis of the head. Surprisingly, at certain orientations, spectacles yielded higher maximum pressures (80%) and goggles yielded larger impulses (150%) than those observed without eyewear. The findings from this study will aid in the design of eyewear that provides better protection against BOP.

Experimental study of the overpressures generated by the detonation of spherical air-hydrocarbon gaseous mixtures

International Nuclear Information System (INIS)

Brossard, J.

1978-01-01

The characteristics of the pressure waves transmitted by detonation of gaseous mixtures to the surrounding air were measured by tests made near the ground level in 1 to 54 m 3 spherical balloons containing air-acetylene or air-ethylene mixtures. As concerns the peak overpressure Δp, a theoretical dimensional analysis in accordance with the experimental results shows that Δp can be expressed as a function of two independent variables, which are the radial distance R and the volume V of the balloon . A semi-empirical formula, including ground effects, is proposed and its present validity range is given. (author)

Comparison of under-pressure and over-pressure pulse tests conducted in low-permeability basalt horizons at the Hanford Site, Washington State

Thorne, P.D.; Spane, F.A. Jr.

1984-10-01

Over-pressure pulse tests (pressurized slug tests have been widely used by others for hydraulic characterization of low-permeability ( -8 m/sec) rock formations. Recent field studies of low-permeability basalt horizons at the Hanford Site, Washington, indicate that the under-pressure pulse technique is also a viable test method for hydraulic characterization studies. For over-pressure pulse tests, fluid within the test system is rapidly pressurized and the associated pressure decay is monitored as compressed fluid within the test system expands and flows into the test formation. Under-pressure pulse tests are conducted in a similar manner by abruptly decreasing the pressure of fluid within the test system, and monitoring the associated increase in pressure as fluid flows from the formation into the test system. Both pulse test methods have been used in conjunction with other types of tests to determine the hydraulic properties of selected low-permeability basalt horizons at Hanford test sites. Results from both pulse test methods generally provide comparable estimates of hydraulic properties and are in good agreement with those from other tests

2001-03-01

The major motivation of this study was to develop a methodology for fracture assessment of surface defects in the 01 reactor pressure vessel under cold loading scenarios, particularly the cold over-pressurization event. According to a previous study, the FENIX project, the cold over-pressurization of the O1 reactor is a limiting loading case, as the ductile/brittle transition temperature (RT NDT ) of certain welds in the O1 beltline region may be over 100 deg C at the-end-of-life condition. The FENIX project gave values of the acceptable and critical crack depth to be equal to the thickness of the cladding layer (about 6 mm) under this load case using the ASME K Ic reference curve methodology. This study is aimed to develop a methodology to give a more precise fracture assessment of the O1 reactor under cold loading scenarios. Some of the main objectives of this study have been as below: To prepare a material which can simulate the mechanical properties and RT NDT of the O1 reactor at the end-of-life conditions. To conduct a fracture mechanics test program to cover the essential influencing factors, such as crack geometry (shallow and deep cracks) and loading condition (uniaxial and biaxial) on the cleavage fracture toughness. To perform fracture mechanics analyses to identify a suitable methodology for assessment of the experimental results. To study the responses of engineering fracture assessment methods to the experimental results from the clad specimens. To propose a fracture assessment procedure for determination of the acceptable and critical flaw sizes in the 01 reactor under the cold loading events. A test program consisted of experiments on standard SEN(B) specimens and clad beams, containing surface cracks was conducted during the course of this project. A total of nine clad beams and clad cruciform specimens were tested under uniaxial and biaxial loading. The test material is reactor steel of type A 508 Grade B, which is specially heat-treated to

Explosion protection technologies are based on the formation of a shock wave mitigation barrier between the protection site and the explosion site. Contemporary protective systems use water mist as an extinguishing barrier. To achieve high effectiveness of the protective system, proper selection of water mist characteristics is important. The main factors defining shock wave attenuation in water mist include droplet size distribution, water concentration in the mist, droplet velocity and geometric properties of mist. This paper examines the process of attenuation of shock waves in mist with droplets ranging from 25 to 400 microns under different conditions of water mist location. Experiments were conducted at the Mining Institute with the use of a shock tube to study the processes of explosion suppression by a water mist barrier. The shock tube consists of a blast chamber, a tube, a system for the dosed supply of water, sensors, data recording equipment, and a process control module. Shock wave overpressure reduction coefficient was studied in the shock tube under two different locations of water mist: a) when water mist is created in direct contact with blast chamber and b) the blast chamber and the mist are separated by air space. It is established that in conditions when the air space distance between the blast chamber and the mist is 1 meter, overpressure reduction coefficient is 1.5-1.6 times higher than in conditions when water mist is created in direct contact with blast chamber.

Power transformer rupture and fire resulting from an arcing fault inside the tank usually leads to significant security risks and serious economic loss. In order to reveal the essence of tank deformation or explosion, this paper presents a 3-D numerical computational tool to simulate the structural dynamic behavior due to overpressure inside transformer tank. To illustrate the effectiveness of the proposed method, a 17.3 MJ and a 6.3 MJ arcing fault were simulated on a real full-scale 360MVA/220kV oil-immersed transformer model, respectively. By employing the finite element method, the transformer internal overpressure distribution, wave propagation and von-Mises stress were solved. The numerical results indicate that the increase of pressure and mechanical stress distribution are non-uniform and the stress tends to concentrate on connecting parts of the tank as the fault time evolves. Given this feature, it becomes possible to reduce the risk of transformer tank rupture through limiting the fault energy and enhancing the mechanical strength of the local stress concentrative areas. The theoretical model and numerical simulation method proposed in this paper can be used as a substitute for risky and costly field tests in fault overpressure analysis and tank mitigation design of transformers.

The Pamplona zone fold and thrust belt is the offshore expression of convergence and shallow subduction of the Yakutat microplate beneath North America in the northeastern Alaska subduction zone. The combination of convergent tectonics and glaciomarine sedimentary processes create patterns of deformation and deposition resulting in a shallow sedimentary sequence with varying compaction, fluid pressure, and fault activity. We propose that velocity variations observed in our tomographic analysis represent long-lived fluid overpressure due to loading by ice sheets and sediments. Regions with bathymetric and stratigraphic evidence of recent ice sheets and associated sedimentation should be collocated with evidence of overpressure (seismic low velocity zones) in the shallow sediments. Here, we compare a velocity model with shelf seismic stratigraphic facies and modern seafloor morphology. To document glacially derived morphology we use high resolution bathymetry to identify channel and gully networks on the western Yakutat shelf-slope then analyze cross-channel shape indices across the study area. We use channel shape index measurements as a proxy of recent ice-proximal sedimentation based on previously published results that proposed a close correlation. Profiles taken at many locations were fitted with a power function and assigned a shape - U-shape channels likely formed proximal to recent ice advances. Detailed velocity models were created by a combination of streamer tomography and pre-stack depth migration velocities with seismic data including: a 2008 R/V Langseth dataset from the St. Elias Erosion and Tectonics Project (STEEP); and a 2004 high-resolution R/V Ewing dataset. Velocity-porosity-permeability relationships developed using IODP Expedition 341 drilling data inform interpretation and physical properties analyses of the shallow sediments.

Compaction of TOC-rich shales due to kerogen conversion. Implications for fluid flow and overpressure

Hanebeck, D.; Krooss, B.M.; Leythaeuser, D.

TOC-rich shales (10% TOC) have been artificially matured at temperatures between 200 and 350 deg C under controlled axial stress (20 - 40 MPa) for up to 350 hours. The volume change of the cylindrical samples was monitored continuously throughout the experiment. The performed experiments showed that the compaction associated with the thermal decomposition of the kerogen is significantly larger under hydrous than under dry pyrolysis conditions. This observation points at an important role of water in the conversion of kerogen. Semi quantitative permeability tests indicated that sample permeability had decreased at least one order of magnitude after the compaction pyrolysis experiments. This permeability reduction in combination with the observed compaction is the most probable mechanism for overpressure formation in TOC-rich source rock sequences. (author)

"... Good population health is a crucial input into poverty reduction, economic growth and long-term economic development... This point is widely recognised by analysts and policy makers, but is greatly underestimated in its qualitative and quantitative significance, and in the investment allocations of many developing country and donor governments."--Commission on Macroeconomics and Health The international health development scene has changed rapidly during the past 5 years. From being a merely bilateral effort together with a few multilateral organisations and many NGOs new global partnerships have entered the scene and become major funding agencies. The provision of aid has also changed from small-scale project basis to financial support of large programmes. The purpose of this article is to describe some of the major transformations taken place in the organising, delivery and objective of international health development. But before presenting the new international health development agenda, a short introduction to the challenges inducing the need for renewed thinking about international aid is shortly presented.

The determination of blast overpressures and fallout radiation doses at points on a sufficiently fine grid, for any part or for the whole of the UK, and for any postulated attack, is an essential element in the systematic assessment of casualties, the estimation of numbers of homeless, and the evaluation of life-saving measures generally. Models are described which provide the required blast and dose values and which are intended to supersede existing models which were introduced in 1971. The factors which affect blast and, more particularly, dose values are discussed, and the way in which various factors are modelled is described. The models are incorporated into separate computer programs which are described, the outputs of which are stored on magnetic tape for subsequent use as required. (author)

Possible mechanism of horizontal overpressure generation of the Khibiny, Lovozero, and Kovdor ore clusters on the Kola Peninsula

The paper discusses questions related to the generation of increasing crustal horizontal compressive stresses compared to the idea of the standard gravitational state at the elastic stage or even from the prevalence of horizontal compression over vertical stress equal to the lithostatic pressure. We consider a variant of superfluous horizontal compression related to internal lithospheric processes occurrin in the crust of orogens, shields, and plates. The vertical ascending movements caused by these motions at the sole of the crust or the lithosphere pertain to these and the concomitant exogenic processes giving rise to denudation and, in particular, to erosion of the surfaces of forming rises. The residual stresses of the gravitational stressed state at the upper crust of the Kola Peninsula have been estimated for the first time. These calculations are based on the volume of sediments that have been deposited in Arctic seas beginning from the Mesozoic. The data speak to the possible level of residual horizontal compressive stresses up to 90 MPa in near-surface crustal units. This estimate is consistent with the results of in situ measurements that have been carried out at the Mining Institute of the Kola Science Center, Russian Academy of Sciences (RAS), for over 40 years. It is possible to forecast the horizontal stress gradient based on depth using our concept on the genesis of horizontal overpressure, and this forecasting is important for studying the formation of endogenic deposits.

Measured air overpressures, soil-particle pressures, and slumps during the pre-ASIAGO U2Ar stemming experiment

1978-01-04

On November 15, 1976, Lawrence Livermore Laboratory completed its first comprehensive stemming experiment for measuring downhole parameters while varying fill material and rate. Stemming can be defined as backfilling a hole in which a device has been placed to prevent leakage of radioactive materials or gases to the surface. A computer code is being developed for stemming operations, and this experiment was designed to measure parameters under different stemming conditions so the code could be verified and modified. The experiment was conducted in the lower half of a steel-cased, 4-ft-diam, 2000-ft-deep hole at Nevada Test Site. The two stemming materials used in the experiment, Overton sand and LLL II mix, were tested at three fill rates. Significant results of this experiment included successful measurement of downhole air overpressures, vertical and horizontal soil-particle pressures, and temperature. Vertical soil-particle pressures were higher than expected. All surface measurements were valid. The slump-displacement measurements system provided a timing mark to indicate the occurrence of a slump. A major slump occurred on the third day of stemming; a minor slump occurred on the fourth day.

A U.S. developer's introduction to international independent power development

International Nuclear Information System (INIS)

Goodwin, L.M.

1993-01-01

Because US developers have had significant experience developing independent power projects in the US during the fifteen years since the Public Utility Regulatory Policies Act (''PURPA'') was passed, US developers have been some of the most aggressive participants in the early stages of international independent power development. However, US developers who attempt to transplant their US experience directly to foreign markets may be in for a rude awakening. Despite the similarities, there are significant differences between energy project development within the US and development in international markets. The purpose of this paper is to explore these differences, and to review some of the new considerations that experienced US developers will have to deal with in developing international projects

Developing International Personas

DEFF Research Database (Denmark)

Jensen, Iben; Hautopp, Heidi; Nielsen, Lene

2017-01-01

Personas have become a popular method in new product development. Personas have traditionally, and are still, primarily created to represent users from a single national culture at a time during the design process. This, however, is unsatisfactory for companies operating on a global market...... as they show an increasing interest in international personas. However, research on personas in a global context is limited. To address this gap, this paper provides an overview of extant research on international personas. Secondly, it presents an empirical study on challenges Danish IT companies experience...... when using the persona method to collect and present insights about their international users. A key finding in both the literature review and the empirical study was the ambiguity concerning the concept of culture. Therefore, the paper draws on theories about culture, and especially practice theory...

Behavior and evaluation of an existing underground structure subjected to impulsive loads from an internal explosion

International Nuclear Information System (INIS)

Keller, M.D.; Khan, P.K.

1997-12-01

An explosion is the result of a rapid chemical reaction which generates transient air pressure waves called blast waves. There has been much research on the processes of blast wave formation, propagation of blast waves, and quantification of the incident and reflected blast overpressures. The magnitude of blast overpressure, in a partially vented environment, is mainly a function of the type and quantity of detonating material, the amount of available venting, and the orientation and configuration of the reflecting surfaces. In addition to blast overpressure, an explosion can also generate high energy missiles (such as fragments), shock loads, and rapid rise of temperature in the confined space. This study concentrates on the effects of blast overpressure on a 40 feet diameter reinforced concrete cylinder with a hemispherical dome roof, supported on a 3 feet thick reinforced concrete pad, and buried under a minimum of 15 feet of soil used for radiation shielding at the top of the dome. The scope of this study is to determine whether the structure can withstand the blast overpressure generated by the postulated explosion without exceeding allowable design criteria

Open development networked innovations in international development

CERN Document Server

Reilly, Katherine M A

2014-01-01

The emergence of open networked models made possible by digital technology has the potential to transform international development. Open network structures allow people to come together to share information, organize, and collaborate. Open development harnesses this power, to create new organizational forms and improve people's lives; it is not only an agenda for research and practice but also a statement about how to approach international development. In this volume, experts explore a variety of applications of openness, addressing challenges as well as opportunities. Open development requires new theoretical tools that focus on real world problems, consider a variety of solutions, and recognize the complexity of local contexts. After exploring the new theoretical terrain, the book describes a range of cases in which open models address such specific development issues as biotechnology research, improving education, and access to scholarly publications. Contributors then examine tensions between open model...

Rapid and low cost off-line thin layer chromatography-total reflection X-ray fluorescence spectrometry and overpressured thin layer chromatography-total reflection X-ray fluorescence spectrometry methods have been developed for separation of 25 ng of each As(III), As(V), monomethyl arsonic acid and dimethylarsinic acid applying a PEI cellulose stationary phase on plastic sheets and a mixture of acetone/acetic acid/water = 2:1:1 (v/v/v) as eluent system. The type of eluent systems, the amounts (25-1000 ng) of As species applied to PEI cellulose plates, injection volume, development distance, and flow rate (in case of overpressured thin layer chromatography) were taken into consideration for the development of the chromatographic separation. Moreover, a microdigestion method employing nitric acid for the As spots containing PEI cellulose scratched from the developed plates divided into segments was developed for the subsequent total reflection X-ray fluorescence spectrometry analysis. The method was applied for analysis of root extracts of cucumber plants grown in As(III) containing modified Hoagland nutrient solution. Both As(III) and As(V) were detected by applying the proposed thin layer chromatography/overpressured thin layer chromatography-total reflection X-ray fluorescence spectrometry methods

Analyses of a steel containment vessel with an outer contact structure under severe internal overpressurization conditions

International Nuclear Information System (INIS)

Porter, V.L.

1994-01-01

Many Mark-I and Mark-II BWR plants are designed with a steel vessel as the primary containment. Typically, the steel containment vessel (SCV) is enclosed within a reinforced concrete shield building with only a small gap (74-90 mm) separating the two structures. This paper describes finite element analyses performed to evaluate the effects of contact and friction between a steel containment vessel and an outer contact structure when the containment vessel is subjected to large internal pressures. These computations were motivated by a joint program on containment integrity involving the Nuclear Power Engineering Corporation (NUPEC) of Japan, the US Nuclear Regulatory Commission (NRC), and Sandia National Laboratories for testing model containments. Under severe accident loading conditions, the steel containment vessel in a typical Mark-I or Mark-II plant may deform under internal pressurization such that it contacts the inner surface of a shield building wall. (Thermal expansion from increasing accident temperatures would also close the gap between the SCV and the shield building, but temperature effects are not considered in these analyses.) The amount and location of contact and the pressure at which it occurs all affect how the combined structure behaves. A preliminary finite element model has been developed to analyze a model of a typical steel containment vessel con-ling into contact with an outer structure. Both the steel containment vessel and the outer contact structure were modelled with axisymmetric shell finite elements. Of particular interest are the influence that the contact structure has on deformation and potential failure modes of the containment vessel. Furthermore, the coefficient of friction between the two structures was varied to study its effects on the behavior of the containment vessel and on the uplift loads transmitted to the contact structure. These analyses show that the material properties of an outer contact structure and the amount

The Impact of Transport on International Trade Development

Directory of Open Access Journals (Sweden)

Pavlović Duško

2016-09-01

Full Text Available International trade implies transport of specific quantity of goods to (frequently large distances, the success of which depends on the safety and speed of delivery. These are greatly conditioned by the quality of means of transport and infrastructure. This is why international trade development is affected by transport, and the development of means of transport and infrastructure is, to a great extent, influenced by demand for international delivery of various commodities. This paper looks at the interdependence of international trade and transport, showing how transport played a very significant role in international trade development in the past as it does today, commensurate to the role of international trade in the development of carriers and transport infrastructure.

International certification in developing countries: the role of internal and external institutional pressure.

Science.gov (United States)

Fikru, Mahelet G

2014-11-01

This paper examines the different internal and external institutional factors that affect the decision of businesses in developing countries to adopt international certification (IC). Past studies focus on pressure from international laws, the role of multinationals, and businesses mimicking practices of their counterparts in developed countries. This paper finds that, in addition to these external factors, internal factors may have a significant role. Even though environmental regulation is weak in developing countries, governments do not ignore industrial pollution and casualties. They respond by increasing bureaucratic regulations for businesses and this can affect the decision to adopt IC. Furthermore, internal pressure may come from workers' unions that push for a safe and healthy working environment. Published by Elsevier Ltd.

A new restoration of the NFP20-East cross section and possible tectonic overpressure in the Penninic Adula Nappe (Central Alps)

Science.gov (United States)

Pleuger, J.; Podladchikov, Y.

2012-04-01

The Adula Nappe in the eastern Central Alps is one of the four units in the Alps from which ultrahigh-pressure rocks have been reported. Several very different models for its tectonic history have been published but none of these models is fully satisfactory. In the models of Schmid et al. (1996) and Engi et al. (2001), the main mechanism of exhumation is assumed to be extrusion. The extrusion models require top-to-the-hinterland, i.e. top-to-the-south faulting in the hanging wall of the exhuming nappe for which there is no evidence. Froitzheim et al. (2003) proposed a scenario with two different subduction zones, an internal one in which the South Penninic and Briançonnais domains were subducted, and an external one in which the North Penninc domain and the European margin, including the Adula nappe, were subducted. In this model, the exhumation of the Adula nappe results from the subduction of the overlying sub-Briançonnais and sub-South-Penninic mantle in the internal subduction zone. The Adula nappe would then have been exhumed from below into a top-to-the-north shear zone also affecting the overriding Briançonnais units. The main shortcoming of this model is that otherwise there is little evidence for two Alpine subduction zones. All the models cited above are based on the conversion of peak pressures obtained from geobarometry to depth by assuming lithostatic pressures. This results in a much greater burial depth of the Adula Nappe with respect to the surrounding units which poses major problems when trying to reconcile maximum burial depths of the Penninic nappes with their structural record. We performed a new restoration of the NFP20-East cross section (Schmid et al. 1996) without applying a lithostatic pressure-to-depth conversion but a purely geometrical restoration of deformation events in the Penninic nappe stack. The major constraints on these reconstructions are given by strain estimates for the major deformation phases in the units overlying the

MSSV Modeling for Wolsong-1 Safety Analysis

Energy Technology Data Exchange (ETDEWEB)

Moon, Bok Ja; Choi, Chul Jin; Kim, Seoung Rae [KEPCO EandC, Daejeon (Korea, Republic of)

2010-10-15

The main steam safety valves (MSSVs) are installed on the main steam line to prevent the overpressurization of the system. MSSVs are held in closed position by spring force and the valves pop open by internal force when the main steam pressure increases to open set pressure. If the overpressure condition is relieved, the valves begin to close. For the safety analysis of anticipated accident condition, the safety systems are modeled conservatively to simulate the accident condition more severe. MSSVs are also modeled conservatively for the analysis of over-pressurization accidents. In this paper, the pressure transient is analyzed at over-pressurization condition to evaluate the conservatism for MSSV models

Purpose This paper aims to highlight the importance of leadership development for all physicians within a competency-based medical education (CBME) framework. It describes the importance of timely international collaboration as a key strategy in promoting physician leadership development. Design/methodology/approach The paper explores published and Grey literature around physician leadership development and proposes that international collaboration will meet the expanding call for development of leadership competencies in postgraduate medical learners. Two grounding frameworks were used: complexity science supports adding physician leadership training to the current momentum of CBME adoption, and relational cultural theory supports the engagement of diverse stakeholders in multiple jurisdictions around the world to ensure inclusivity in leadership education development. Findings An international collaborative identified key insights regarding the need to frame physician leadership education within a competency-based model. Practical implications International collaboration can be a vehicle for developing a globally relevant, generalizable physician leadership curriculum. This model can be expanded to encourage innovation, scholarship and program evaluation. Originality/value A competency-based leadership development curriculum is being designed by an international collaborative. The curriculum is based on established leadership and education frameworks. The international collaboration model provides opportunities for ongoing sharing, networking and diversification.

Understanding the development of international environmental agreements

DEFF Research Database (Denmark)

Stærdahl, Jens

There are many different theoretical schools concerned with how international regimes develop, and each supplies its own interpretation focusing on one or a few aspects of the process. Such ‘one shot’ explanations may be fruitful for scientific debate, but less useful as conceptual frameworks...... for practitioners and planners manoeuvring in a complex world. On the basis of a review of selected theories of international and environmental regulation, this article initiates the development of a conceptual framework for understanding the development of internationalenvironmental agreements. The point...... of departure for developing the model is the actor-structure debate within social science and theory of international relations. Based on critical realism, a framework is developed specifying the relation between collective action problem situations and negotiation situations. It is argued that the main...

Internal radiation dose assessment involves biokinetic models, the corresponding parameters, measured data, and many assumptions. Every component considered in the internal dose assessment has its own uncertainty, which is propagated in the intake activity and internal dose estimates. For research or scientific purposes, and for retrospective dose reconstruction for accident scenarios occurring in workplaces having a large quantity of unsealed radionuclides, such as nuclear power plants, nuclear fuel cycle facilities, and facilities in which nuclear medicine is practiced, a quantitative uncertainty assessment of the internal dose is often required. However, no calculation tools or computer codes that incorporate all the relevant processes and their corresponding uncertainties, i.e., from the measured data to the committed dose, are available. Thus, the objective of the present study is to develop an integrated probabilistic internal-dose-assessment computer code. First, the uncertainty components in internal dosimetry are identified, and quantitative uncertainty data are collected. Then, an uncertainty database is established for each component. In order to propagate these uncertainties in an internal dose assessment, a probabilistic internal-dose-assessment system that employs the Bayesian and Monte Carlo methods. Based on the developed system, we developed a probabilistic internal-dose-assessment code by using MATLAB so as to estimate the dose distributions from the measured data with uncertainty. Using the developed code, we calculated the internal dose distribution and statistical values (e.g. the 2.5{sup th}, 5{sup th}, median, 95{sup th}, and 97.5{sup th} percentiles) for three sample scenarios. On the basis of the distributions, we performed a sensitivity analysis to determine the influence of each component on the resulting dose in order to identify the major component of the uncertainty in a bioassay. The results of this study can be applied to various

"International regime for advancing lunar development"

Science.gov (United States)

Beldavs, VZ

2017-09-01

A specific concern regarding the Moon Treaty is the provision for sharing the wealth gained from space with developing countries that have not invested and taken risks in making possible space materials utilization. Article 11, par. 7 states "The main purposes of the international regime to be established shall include: (a) The orderly and safe development of the natural resources of the moon; (b) The rational management of those resources; (c) The expansion of opportunities in the use of those resources; (d) An equitable sharing by all States Parties in the benefits derived from those resources, whereby the interests and needs of the developing countries, as well as the efforts of those countries which have contributed either directly or indirectly to the exploration of the moon, shall be given special consideration." Whether the Moon Treaty in its present form or modified to be acceptable to more parties or the Moon Treaty is ignored, the language of Article 11, paragraph 7 can be used to construct an international regime for lunar development that can meet the requirements of commercial business as well as of states that provide support for lunar development as well as developing countries that may have played a modest role in making lunar development possible. This paper will consider options for constructing an international regime for lunar development.

Seismic chimneys in the Southern Viking Graben - Implications for palaeo fluid migration and overpressure evolution

Science.gov (United States)

Karstens, Jens; Berndt, Christian

2015-02-01

Detailed understanding of natural fluid migration systems is essential to minimize risks during hydrocarbon exploration and to evaluate the long-term efficiency of the subsurface storage of waste water and gas from hydrocarbon production as well as CO2. The Southern Viking Graben (SVG) hosts numerous focused fluid flow structures in the shallow (expressions of vertical fluid conduits are variously known as seismic chimneys or pipes. Seismic pipes are known to form large clusters. Seismic chimneys have so far been described as solitary structures. Here, we show that the study area in the SVG hosts more than 46 large-scale vertical chimney structures, which can be divided in three categories implying different formation processes. Our analysis reveals that seal-weakening, formation-wide overpressure and the presence of free gas are required to initiate the formation of vertical fluid conduits in the SVG. The presence of numerous vertical fluid conduits implies inter-stratigraphic hydraulic connectivity, which significantly affects the migration of fluids in the subsurface. Chimney structures are important for understanding the transfer of pore pressure anomalies to the shallow parts of the basin.

Current state of knowledge on the behavior of steel liners in concrete containments subjected to overpressurization loads

International Nuclear Information System (INIS)

von Riesemann, W.A.; Parks, M.B.

1993-01-01

In the United States, concrete containment buildings for commercial nuclear power plants have steel liners that act as the intemal pressure boundary. The liner abuts the concrete, acting as the interior concrete form. The liner is attached to the concrete by either studs or by a continuous structural shape (such as a T-section or channel) that is either continuously or intermittently welded to the liner. Studs are commonly used in reinforced concrete containments, while prestressed containments utilize a structural element as the anchorage. The practice in some countries follows the US practice, while in other countries the containment does not have a steel liner. In this latter case, there is a true double containment, and the annular region between the two containments is vented. This paper will review the practice of design of the liner system prior to the consideration of severe accident loads (overpressurization loads beyond the design conditions)

Mucosal wave characteristics in three voice modes (fry, hiss & overpressure) produced by a female speaker: a preliminary study using stroboscopy, HSDI and analyzed by kymography, P-FFT & Nyquist plots

Science.gov (United States)

Izdebski, Krzysztof; Ward, Ronald R.; Yan, Yuling

2012-02-01

HSDI provides a whole new way to investigate visually intra-laryngeal behavior and posturing during phonation by providing detailed real-time information about laryngeal biomechanics that include observations about mucosal wave, wave motion directionality, glottic area wave form, asymmetry of vibrations within and across vocal folds and contact area of the glottis including posterior commissure closure. These observations are fundamental to our understanding and modeling of both normal and disordered phonation. In this preliminary report we focus on direct HSDI in vivo observations of not only the glottic region, but also on the entire supraglottic laryngeal posturing during fry, breathy/hiss and over-pressured phonation modes produced in a non-pathological settings. Analysis included spatio-temporal vibration patterns of vocal folds, multi-line kymograms, spectral PFFT analysis, and Nyquist spatio-temporal plots. The presented examples reveal that supraglottic contraction assists in prolonged closed phase of the vibratory cycle, and that prolonged closed phase is longest in fry and overpressure and shortest albeit complex in hiss. Hiss also allows for vocal fold vibration despite glottis separation. These findings need to be compared to pathologic phonation representing the three voice modes to derive at better differential diagnosis.

The increasing number of people living with multiple chronic conditions in addition to an index condition has become an international healthcare priority. Health education curricula have been developed alongside single condition frameworks in health service policy and practice and need redesigning to incorporate optimal management of multiple conditions. Our aims were to evaluate current teaching and learning about comorbidity care amongst the global population of healthcare students from different disciplines and to develop an International Comorbidity Education Framework (ICEF) for incorporating comorbidity concepts into health education. We surveyed nursing, medical and pharmacy students from England, India, Italy and Sweden to evaluate their understanding of comorbidity care. A list of core comorbidity content was constructed by an international group of higher education academics and clinicians from the same disciplines, by searching current curricula and analysing clinical frameworks and the student survey data. This list was used to develop the International Comorbidity Education Framework. The survey sample consisted of 917 students from England (42%), India (48%), Italy (8%) and Sweden (2%). The majority of students across all disciplines said that they lacked knowledge, training and confidence in comorbidity care and were unable to identify specific teaching on comorbidities. All student groups wanted further comorbidity training. The health education institution representatives found no specific references to comorbidity in current health education curricula. Current clinical frameworks were used to develop an agreed list of core comorbidity content and hence an International Comorbidity Education Framework. Based on consultation with academics and clinicians and on student feedback we developed an International Comorbidity Education Framework to promote the integration of comorbidity concepts into current healthcare curricula.

Simulations of the design basis accident at conditions of power increase and the o transient of MSIV at overpressure conditions of the Laguna Verde Power Station

International Nuclear Information System (INIS)

Araiza M, E.; Nunez C, A.

2001-01-01

This document presents the analysis of the simulation of the loss of coolant accident at uprate power conditions, that is 2027 MWt (105% of the current rated power of 1931MWt). This power was reached allowing an increase in the turbine steam flow rate without changing the steam dome pressure value at its rated conditions (1020 psiaJ. There are also presented the results of the simulation of the main steam isolation va/ve transient at overpressure conditions 1065 psia and 1067 MWt), for Laguna Verde Nuclear Power Station. Both simulations were performed with the best estimate computer code TRA C BF1. The results obtained in the loss of coolant accident show that the emergency core coolant systems can recover the water level in the core before fuel temperature increases excessively, and that the peak pressure reached in the drywell is always below its design pressure. Therefore it is concluded that the integrity of the containment is not challenged during a loss of coolant accident at uprate power conditions.The analysis of the main steam isolation valve transients at overpressure conditions, and the analysis of the particular cases of the failure of one to six safety relief valves to open, show that the vessel peak pressures are below the design pressure and have no significant effect on vessel integrity.

Blast overpressure induced axonal injury changes in rat brainstem and spinal cord

Directory of Open Access Journals (Sweden)

Srinivasu Kallakuri

2015-01-01

Full Text Available Introduction: Blast induced neurotrauma has been the signature wound in returning soldiers from the ongoing wars in Iraq and Afghanistan. Of importance is understanding the pathomechansim(s of blast overpressure (OP induced axonal injury. Although several recent animal models of blast injury indicate the neuronal and axonal injury in various brain regions, animal studies related to axonal injury in the white matter (WM tracts of cervical spinal cord are limited. Objective: The purpose of this study was to assess the extent of axonal injury in WM tracts of cervical spinal cord in male Sprague Dawley rats subjected to a single insult of blast OP. Materials and Methods: Sagittal brainstem sections and horizontal cervical spinal cord sections from blast and sham animals were stained by neurofilament light (NF-L chain and beta amyloid precursor protein immunocytochemistry and observed for axonal injury changes. Results: Observations from this preliminary study demonstrate axonal injury changes in the form of prominent swellings, retraction bulbs, and putative signs of membrane disruptions in the brainstem and cervical spinal cord WM tracts of rats subjected to blast OP. Conclusions: Prominent axonal injury changes following the blast OP exposure in brainstem and cervical spinal WM tracts underscores the need for careful evaluation of blast induced injury changes and associated symptoms. NF-L immunocytochemistry can be considered as an additional tool to assess the blast OP induced axonal injury.

ISO: international standards development for nuclear technology

International Nuclear Information System (INIS)

Becker, K.

1981-01-01

The importance of internationally recognized standards for nuclear technology and safety is rapidly increasing for technical as well as economical and political reasons such as public acceptance and nuclear technology transfer to developing countries. The need for such standards is also evident because of the large number of nuclear installations sited close to international borders, and the export of nuclear installations from relatively few supplier countries to a large number of user countries. It is the purpose of this report to describe briefly the history, organizational structures and procedures, goals, accomplishments, problems, and future needs of the relevant activities of the International Organization for Standardization (ISO). ISO is composed of the partly governmental, partly non-governmental national standards bodies of 86 countries including China. The work of its Technical Committee (TC) 85 'Nuclear Energy' is mostly concerned with industrial applications, contractual aspects and international communication, for the benefit of both developed and developing countries. It works in close liaison with IAEA, which develops Codes and Guides addressed mainly to the regulatory aspects of nuclear power plants in developing countries. ISO/TC 85 has four sub-committees dealing with: (a) Terminology, Definitions, Units and Symbols (Secretariat USA, four working groups (WGs)); (b) Radiation Protection (Secretariat France, ten WGs); (c) Power Reactor Technology (Secretariat Sweden, nine WGs); (d) Nuclear Fuel Technology (Secretariat F.R.

MSc. Bardhok Bashota

2012-06-01

Full Text Available Karl Popper rightly says that “real starting point for each research is set based on assumptions of reality, not only based on the real facts”. The text below was prepared In accordance with this logic, where the Theories of International Development are treated especially focusing on International Economic Development. Therefore, theoretical reflections present assumption side, and study of many empirically measured data will correspond with real facts, because with ought these facts assumption would be useless. Technically this writing consists of two parts: in the first part are elaborated all theoretical and practical characteristics of overall international development, while in a second part as a case study will be Economic Development i Kosovo. From methodological point of view this is a comparative study and based on statistical data, while problem treating approach is critical and explanatory. As it will be understood later, development theories have been decisively influenced by economic thinking, and the focus on this dimension responds best to the nature of the term development. On the other hand the fact of unfolding economical development will reflect interference and the nature of it’s inter politics. Today economic development becomes a worldwide goal, having a considerable place in most of the literature with economic content. Also, here are presented as well examples from different practices that reflect economic development in different periods and places. Here is presented international economic development starting with a brief description of a genealogy of this development and ways of economic development back that time. It is of a special importance elaboration through theoretical approach on the creation of capital and economic development, as  mercantilist theory, classic and neo classic theory, than capitalization and Socialism-Marxism. To better understand the nature of economic development, the focus falls on

Simulation of overpressure events with a Laguna Verde model for the RELAP code to conditions of extended power up rate

International Nuclear Information System (INIS)

Rodriguez H, A.; Araiza M, E.; Fuentes M, L.; Ortiz V, J.

2012-10-01

In this work the main results of the simulation of overpressure events are presented using a model of the nuclear power plant of Laguna Verde developed for the RELAP/SCDAPSIM code. As starting point we have the conformation of a Laguna Verde model that represents a stationary state to similar conditions to the operation of the power station with Extended Power Up rate (EPU). The transitory of simulated pressure are compared with those documented in the Final Safety Analysis Report of Laguna Verde (FSAR). The results of the turbine shot transitory with and without by-pass of the main turbine are showed, and the event of closes of all the valves of main vapor isolation. A preliminary simulation was made and with base in the results some adjustments were made for the operation with EPU, taking into account the Operation Technical Specifications of the power station. The results of the final simulations were compared and analyzed with the content in the FSAR. The response of the power station to the transitory, reflected in the model for RELAP, was satisfactory. Finally, comments about the improvement of the model are included, for example, the response time of the protection and mitigation systems of the power station. (Author)

Probability analysis of MCO over-pressurization during staging

International Nuclear Information System (INIS)

Pajunen, A.L.

1997-01-01

The purpose of this calculation is to determine the probability of Multi-Canister Overpacks (MCOs) over-pressurizing during staging at the Canister Storage Building (CSB). Pressurization of an MCO during staging is dependent upon changes to the MCO gas temperature and the build-up of reaction products during the staging period. These effects are predominantly limited by the amount of water that remains in the MCO following cold vacuum drying that is available for reaction during staging conditions. Because of the potential for increased pressure within an MCO, provisions for a filtered pressure relief valve and rupture disk have been incorporated into the MCO design. This calculation provides an estimate of the frequency that an MCO will contain enough water to pressurize beyond the limits of these design features. The results of this calculation will be used in support of further safety analyses and operational planning efforts. Under the bounding steady state CSB condition assumed for this analysis, an MCO must contain less than 1.6 kg (3.7 lbm) of water available for reaction to preclude actuation of the pressure relief valve at 100 psid. To preclude actuation of the MCO rupture disk at 150 psid, an MCO must contain less than 2.5 kg (5.5 lbm) of water available for reaction. These limits are based on the assumption that hydrogen generated by uranium-water reactions is the sole source of gas produced within the MCO and that hydrates in fuel particulate are the primary source of water available for reactions during staging conditions. The results of this analysis conclude that the probability of the hydrate water content of an MCO exceeding 1.6 kg is 0.08 and the probability that it will exceed 2.5 kg is 0.01. This implies that approximately 32 of 400 staged MCOs may experience pressurization to the point where the pressure relief valve actuates. In the event that an MCO pressure relief valve fails to open, the probability is 1 in 100 that the MCO would experience

International Nuclear Information System (INIS)

Oh, Keun Bae; Choi, Y. M.; Lee, K. S.; Lee, B. W.; Ko, H. S.

1997-06-01

It is essential for Korea to enlarge nuclear energy utilization and development and to develop nuclear fuel cycle technology. However some domestic and international restraints are existing to achieve above goals. Therefore, the consideration for the environmental prospect of nuclear energy development is needed to solve those restraints. The current North Korea's policies and future relations between two countries in Korean peninsular in respect to domestic restraints are examined and forecasted in Chapter 2. This analysis tries to develop new approaches to solve internal and external major problems through forecasting the future on nuclear nonproliferation policy of U. S. An in-depth study on resolving international and inter-Korean restrictions in political and strategic perspectives is carried out in Chapter 3. The various policy alternatives to adjust the constraints of the joint declaration are proposed and analysed in Chapter. It contains also the national commitments that are suggested as ideas on how to advance the long-term nuclear research and development under the present situation. (author). 100 refs

Developments in international bioenergy trade

The aim of this paper is to present a synthesis of the main developments and drivers of international bioenergy trade in IEA Bioenergy Task 40 member countries, based on various country reports written by Task 40 members. Special attention is given to pellet and ethanol trade. In many European countries such as Belgium, Finland, the Netherlands, Sweden and the UK, imported biomass contributes already significantly (between 21% and 43%) to total biomass use. Wood pellets are currently exported by Canada, Finland and (to a small extent) Brazil and Norway, and imported by Sweden, Belgium, the Netherlands, and the UK. In the Netherlands and Belgium, pellet imports nowadays contribute to a major share to total renewable electricity production. Trade in bio-ethanol is another example of a rapidly growing international market. With the EU-wide target of 5.75% biofuels for transportation in 2010 (and 10% in 2020), exports from Brazil and other countries to Europe are likely to rise as well. Major drivers for international bioenergy trade in general are the large resource potentials and relatively low production costs in producing countries such as Canada and Brazil, and high fossil fuel prices and various policy incentives to stimulate biomass use in importing countries. However, the logistic infrastructure both in exporting and importing countries needs to be developed to access larger physical biomass volumes and to reach other (i.e. smaller) end-consumers. It is concluded that international bioenergy trade is growing rapidly, far beyond what was deemed possible only a few years ago, and may in the future in some Task 40 countries surpass domestic biomass use, especially for specific applications (e.g. transport fuels).

ECONOMIC DEVELOPMENT THROUGH AID OR INTERNATIONAL TRADE

Directory of Open Access Journals (Sweden)

Ana Mihei

2010-12-01

Full Text Available Economic development is the supreme goal of modern civilization. This phenomenon is seen not just in terms of growth, but rather as an overall improvement in living standards. Economic development is a national goal, but also an objective of international economic bodies. Talks about development are held in the context of the opposition between developed countries and developing countries.In this article, we discuss whether development aid that originates from industrialized states supports sustainable economic rise of the countries lagging behind and whether it is preferable to let market operate freely, through the liberalization of international trade. Our conclusion is that economic development through the promotion of free trade would be achieved faster and more efficiently, based on net gains from trade and the pride of the peoples who would have won by themselves their daily bread and a place in the global market.

Overpressure generation by load transfer following shale framework weakening due to smectite diagenesis

Science.gov (United States)

Lahann, R.W.; Swarbrick, R.E.

2011-01-01

Basin model studies which have addressed the importance of smectite conversion to illite as a source of overpressure in the Gulf of Mexico have principally relied on a single-shale compaction model and treated the smectite reaction as only a fluid-source term. Recent fluid pressure interpretation and shale petrology studies indicate that conversion of bound water to mobile water, dissolution of load-bearing grains, and increased preferred orientation change the compaction properties of the shale. This results in substantial changes in effective stress and fluid pressure. The resulting fluid pressure can be 1500-3000psi higher than pressures interpreted from models based on shallow compaction trends. Shale diagenesis changes the mineralogy, volume, and orientation of the load-bearing grains in the shale as well as the volume of bound water. This process creates a weaker (more compactable) grain framework. When these changes occur without fluid export from the shale, some of the stress is transferred from the grains onto the fluid. Observed relationships between shale density and calculated effective stress in Gulf of Mexico shelf wells confirm these changes in shale properties with depth. Further, the density-effective stress changes cannot be explained by fluid-expansion or fluid-source processes or by prediagenesis compaction, but are consistent with a dynamic diagenetic modification of the shale mineralogy, texture, and compaction properties during burial. These findings support the incorporation of diagenetic modification of compaction properties as part of the fluid pressure interpretation process. ?? 2011 Blackwell Publishing Ltd.

Promoting Success: A Professional Development Coaching Program for Interns in Medicine.

Science.gov (United States)

Palamara, Kerri; Kauffman, Carol; Stone, Valerie E; Bazari, Hasan; Donelan, Karen

2015-12-01

Residency is an intense period. Challenges, including burnout, arise as new physicians develop their professional identities. Residency programs provide remediation, but emotional support for interns is often limited. Professional development coaching of interns, regardless of their performance, has not been reported. Design, implement, and evaluate a program to support intern professional development through positive psychology coaching. We implemented a professional development coaching program in a large residency program. The program included curriculum development, coach-intern interactions, and evaluative metrics. A total of 72 internal medicine interns and 26 internal medicine faculty participated in the first year. Interns and coaches were expected to meet quarterly; expected time commitments per year were 9 hours (per individual coached) for coaches, 5 1/2 hours for each individual coachee, and 70 hours for the director of the coaching program. Coaches and interns were asked to complete 2 surveys in the first year and to participate in qualitative interviews. Eighty-two percent of interns met with their coaches 3 or more times. Coaches and their interns assessed the program in multiple dimensions (participation, program and professional activities, burnout, coping, and coach-intern communication). Most of the interns (94%) rated the coaching program as good or excellent, and 96% would recommend this program to other residency programs. The experience of burnout was lower in this cohort compared with a prior cohort. There is early evidence that a coaching program of interactions with faculty trained in positive psychology may advance intern development and partially address burnout.

Within the framework of "traditional" programmes, like the joint UNESCO-IUGS "International Geoscience Programme" (IGCP), the "International Continental Scientific Drilling Program" (ICDP), the "Integrated Ocean Drilling Program" (IODP) or the "International Lithosphere Programme" (ILP) numerous opportunities are provided to strengthen postgraduate geo-scientific education of representatives from developing countries. Recently established new initiatives, such as the "International Year of Planet Earth" (IYPE) or UNESCO's Global Network of Geoparks complement these in addition as important components to UNESCO's 'Education for All' programme, notably the youth, as well as to the United Nations Decade of Education for Sustainable Development (2005 - 2014). The "International Year of Planet Earth" is a joint initiative of the International Union of Geological Sciences (IUGS) and UNESCO. The central aims and ambitions of the Year, proclaimed for 2008 by the UN General Assembly, are to demonstrate the great potential of the Earth sciences in building a safer, healthier and wealthier society, and to encourage more widespread and effective application of this potential by targeting politicians and other decision-makers, educational systems, and the general public. Promotion of international collaboration, as well as capacity building and training of students of developing countries in all fields of Earth Sciences seem to be the most appropriate way to meet also the challenges of the IYPE. Another opportunity to improve the international recognition of Earth Scinces, also in developing countries, is the use of Geoparks as a promotional tool for education and popularization of Earth Sciences. Geoparks, notably those included in the European and/or Global Geoparks Networks, provide an international platform of cooperation and exchange between experts and practitioners in geological heritage matters, and are as such excellent instruments in highlighting Earth sciences.

International Convention on the Rights of Persons with Disability: Disability Inclusive Development and International Development Cooperation

Directory of Open Access Journals (Sweden)

Kozue Kay Nagata

2007-09-01

Full Text Available The adoption of the International Convention on the Rights of Persons with Disabilities is a historical momentum for disabled persons and their associates, as well as ODA workers in the development cooperation field all over the world. For the last two decades, persons with disabilities, their associates and professionals working in this field have promoted their human rights, equality, nondiscrimination and full participation. This Convention is beyond the concept of non-discrimination, and it is very comprehensive in its structure, scope and coverage, promoting developmental activities too in order to realize disabled people’s socio-economic rights. Furthermore it calls for international and regional development cooperation. Prior to its adoption, in September 2000 at the Millennium Summit the Member States of the Untied Nations issued the Millennium Declaration, committing themselves to a series of development targets, most of which are to be achieved by 2015. Known as the Millennium Development Goals (MDGs, they represent a framework for achieving sustainable and "just" human development through broadening the benefits of development for all categories individuals, women and men, the poor and the rich, the disabled and the non-disabled. The very first goal of the MDG is the eradication of extreme poverty and hunger. Poverty is both a cause and consequence of disability. Poverty and disability reinforce one another. Thus, it is necessary to ensure that persons with disabilities be an integral part of efforts to achieve MDGs, particularly in the areas of poverty alleviation, primary education, gender, employment and international development cooperation. In the Asian and Pacific region, the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP has proclaimed two decades of disabled persons 1993-2002, and 2003-2013 (to which Iran became a signatory in 1994, and promoted the inclusive, barrier-free and rights

Analyses of a steel containment vessel with an outer contact structure under severe internal overpressurization conditions

International Nuclear Information System (INIS)

Porter, V.L.

1993-01-01

Many Mark-I and Mark-II BWR plants are designed with a steel vessel as the primary containment. Typically, the steel containment vessel (SCV) is enclosed within a reinforced concrete shield building with only a small gap (50--90mm) separating the two structures. This paper describes finite element analyses performed to evaluate the effects of contact and friction between a steel containment vessel and an outer contact structure when the containment vessel is subjected to large internal pressures. These computations were motivated by a joint program on containment integrity involving the Nuclear Power Engineering Corporation (NUPEC) of Japan, the US Nuclear Regulatory Commission (NRC), and Sandia National Laboratories for testing model containments

International Collaboration in the Development of NPP Software

International Nuclear Information System (INIS)

Jiang, S.; Liu, L.; Yu, H.

2015-01-01

In this paper, we first review the progress and current status of international collaboration and technical exchange in the development of nuclear power plant (NPP) software by The State Nuclear Power Software Development Center (SNPSDC) in China. Then we discuss the importance of the international collaboration and exchange in the trend of globalisation of NPP technology. We also identify the role and contribution of professional women in this process. SNPSDC, the first professional software development centre for NPP in China, has been developing COSINE — a self-reliance NPP design and analysis software product with China brand—since 2010. Through participating in OECD/NEA’s joint projects, such as ROSA-2 Project, PKL–3 Project, HYMERES Project and ATLAS Project, SNPSDC shared data with other countries involved with respect to particular areas, such as high quality reactor thermal hydraulics test data. SNPSDC’s engineers have also been actively participating in international technical and research exchange for presenting their innovative work to the community while learning from peers. Our record shows that over 30 papers have been presented in international conferences with respect to nuclear reactor thermal hydraulics, safety analysis, reactor physics and software engineering within the past 4 years. The above international collaboration and technical exchange helped SNPSDC’s engineers to keep up with the state-of-art technology in this field. The large amount of valuable experimental data transferred to SNPSDC ensured the functionality, usability and reliability of software while greatly reduced the cost and shortened the cycle of development. Female engineers and other employees of SNPSDC either drove or got actively involved in a lot of aspects of the above collaboration and exchange, such as technical communication, business negotiation and overseas affairs management. These professional women played an irreplaceable role in this project by

Full Text Available Globalisation has opened economies more, exposing them to more international shocks and increasing the challenges to which domestic economic policies must respond. This paper provides a starting point for the analysis of the impact of international economic developments on the South African economy by means of graphical illustrations, correlations coefficients and in some cases a VAR analysis. Although this paper has shed some light on the importance of international economic developments on the South African economy, more rigorous econometric investigation is needed to validate the arguments and to address many of the unresolved questions.

Development of nuclear technology through International Technical Cooperation programme: Malaysian experience

International Nuclear Information System (INIS)

Ainul Hayati Daud

1997-01-01

In the advent of new technologies and knowledge, countries need to rely on one another for progress and development. At the same time, new challenges to development, which are beyond the competence of any country to approach individually, have emerged. These have led to greater need for international co-operation, particularly among the developing countries. In Malaysia, international technical co-operation has contributed significantly towards the development of nuclear technology. Malaysia has received technical assistance through the multilateral, regional and bilateral co-operation. This assistance complements the efforts of the government to meet the primary objectives of science and technology programme, which are; intensification of R and D capacity and applications of technologies, both acquired and developed, in national development. Over the last one and a half decade, more than 70 projects valued almost USD 15 millions, were implemented under the Technical Assistance Programme of the International Atomic Energy Agency and the Bilateral Technical Assistance Programme of Japan and Australia. Malaysia also has benefited from the regional technical co-operation programme such Regional Co-operative Agreement for Asia and Pacific Region, United Nation Department Programme, International Nuclear Co-operation in Asia. While receiving assistance, Malaysia continues to assist other developing countries in their development efforts in the fields of nuclear technology, through the various international co-operation programmes. This report reviews the technical assistance received through the international co-operation and its contributions towards the development of nuclear technology in Malaysia for period 1980 - 1996

Development of the International Guidelines for Home Health Nursing.

Science.gov (United States)

Narayan, Mary; Farris, Cindy; Harris, Marilyn D; Hiong, Fong Yoke

2017-10-01

Throughout the world, healthcare is increasingly being provided in home and community-based settings. There is a growing awareness that the most effective, least costly, patient-preferred setting is patients' home. Thus, home healthcare nursing is a growing nursing specialty, requiring a unique set of nursing knowledge and skills. Unlike many other nursing specialties, home healthcare nursing has few professional organizations to develop or support its practice. This article describes how an international network of home healthcare nurses developed international guidelines for home healthcare nurses throughout the world. It outlines how the guidelines for home healthcare nursing practice were developed, how an international panel of reviewers was recruited, and the process they used for reaching a consensus. It also describes the plan for nurses to contribute to future updates to the guidelines.

International physical protection standards: support for development and implementation

International Nuclear Information System (INIS)

Soo Hoo, M.S.

2002-01-01

Full text: Since 1972, the IAEA has been a recognized organization in promoting the development of international standards on the physical protection of nuclear materials. This responsibility has continued through the present in the 1999 publication of the fourth revision of INFCIRC/225, the physical protection of nuclear material and nuclear facilities and in being the repository for the convention on the physical protection of nuclear material which was originally published in 1980 as INFCIRC/274. The IAEA has also published other reference documents in support these two standards. With changing world events and greater concern for the physical protection of nuclear materials and facilities, IAEA member states have increased IAEA physical protection responsibilities. Currently, the IAEA is serving as the secretariat for drafting revisions to the physical protection convention. The proposed revisions will strengthen international physical protection standards through the incorporation of physical protection fundamentals that should apply to all nuclear materials in international or domestic use, storage and transport. Furthermore, the physical protection fundamentals would also extend to include nuclear facilities. Presently, the physical protection convention applies only to nuclear materials that are in international transport. To complement efforts to develop and promote international physical protection standards, the IAEA is actively involved in assisting member states with the implementation of the standards. This is accomplished through the delivery of training courses, workshops and hosting other international forums for the exchange of information. Through review services such as the international physical protection advisory service (IPPAS), the IAEA provides advice to member states on the application of international standards at national and facility-specific levels. These services can be followed up with technical support to implement the

Reflections on the development of international nuclear law

International Nuclear Information System (INIS)

Lamm, Vanda

2017-01-01

Over the course of more than seven decades, treaty norms on the production and utilisation of nuclear energy have been developed, which together form a special section within international law. These norms are the consequence of the unique nature of the field, namely that on the one hand some aspects of the uses of nuclear energy should be covered by totally new and special norms (e.g. in the field of disarmament, seeking to eliminate or at least to control the spread of nuclear weapons, and nuclear weapons tests) and on the other hand that several traditional legal solutions were not suitable for the problems that emerged in connection with other uses of nuclear energy (like liability). In this article, three aspects of the development of that special section of international law will be explored, namely: the close connections between the regulation of peaceful and military uses of nuclear energy; the effects of nuclear catastrophes on the development of international nuclear legislation; and the interaction between soft law norms and binding norms in the area of nuclear law

Climate change and developing countries: A role for the Canadian International Development Agency

International Nuclear Information System (INIS)

Ragusa, P.

2000-01-01

The Canadian International Development Agency (CIDA) is primarily responsible for Canada's official development assistance program whose objective is to foster sustainable development in order to reduce poverty and contribute to a more secure, equitable and prosperous world. CIDA programs are directed to the needs of developing countries to assist them in capacity building, to provide financial resources and technology transfer, to help them to meet the cost of adaptation to adverse effects, and to develop and enhance indigenous capabilities. With respect to climate change, CIDA, in concert with other federal government departments, endeavours to maximize Canada's capabilities to meet international environmental commitments and Kyoto climate change targets at the lowest cost, ensure a level playing field with Canada's competitors by maximizing participation of major developed and developing economies in the Kyoto Protocol, and maximize opportunities for Canadian businesses in international projects and initiatives in climate change. Accordingly, the 2000 CIDA Budget provides official development assistance funding of $100 million over four years for technology transfer to help developing countries reduce their greenhouse gas emissions and promote sustainable development. First call for proposals is targeted for August 2001, with assessment of proposals and projects during September and second call for proposals before year end. Major provisions of the Kyoto Protocol, the purposes of the Clean Development Mechanism, the role that CIDA can play in support of implementation of CDM, benefits and opportunities provided by CDM are summarized. Ways in which private sector firms seeking to expand into developing countries can benefit by working with CIDA, are also discussed

Development Internal Problems of Shanghay Cooperation Organization

Directory of Open Access Journals (Sweden)

Oksana Y. Kolegova

2015-01-01

Full Text Available The article analyzes the main internal problems of the Shanghai Cooperation Organization. Particular attention is paid to the conflict of interests of the participating countries, as well as identifying obstacles to strengthen the organization and increase its influence in the international arena. The international organizations are created by the states to meet mutual problems in the course of interstate relations requiring regular cooperation mechanism. Given the background of the Organization, it is important to emphasize that the main reason for the establishment of the Shanghai organization was the need for the united front against the strengthening of the region at the turn of centuries against dangerous trends of terrorism, extremism, separatism, the growth of organized crime. Despite the conflict of interests and the internal and external development challenges thirteen-year history of evolution of the SCO, to some extent proves its effectiveness, moreover, there are the preconditions for its consistent transition to a more comprehensive organization.

[Strategy Development for International Cooperation in the Clinical Laboratory Field].

Science.gov (United States)

Kudo, Yoshiko; Osawa, Susumu

2015-10-01

The strategy of international cooperation in the clinical laboratory field was analyzed to improve the quality of intervention by reviewing documents from international organizations and the Japanese government. Based on the world development agenda, the target of action for health has shifted from communicable diseases to non-communicable diseases (NCD). This emphasizes the importance of comprehensive clinical laboratories instead of disease-specific examinations in developing countries. To achieve this goal, the World Health Organization (WHO) has disseminated to the African and Asian regions the Laboratory Quality Management System (LQMS), which is based on the same principles of the International Organization of Standardization (ISO) 15189. To execute this strategy, international experts must have competence in project management, analyze information regarding the target country, and develop a strategy for management of the LQMS with an understanding of the technical aspects of laboratory work. However, there is no appropriate pre- and post-educational system of international health for Japanese international workers. Universities and academic organizations should cooperate with the government to establish a system of education for international workers. Objectives of this education system must include: (1) training for the organization and understanding of global health issues, (2) education of the principles regarding comprehensive management of clinical laboratories, and (3) understanding the LQMS which was employed based on WHO's initiative. Achievement of these objectives will help improve the quality of international cooperation in the clinical laboratory field.

Strengthening International Collaboration: Geosciences Research and Education in Developing Countries

Science.gov (United States)

Fucugauchi, J. U.

2009-05-01

Geophysical research increasingly requires global multidisciplinary approaches and global integration. Global warming, increasing CO2 levels and increased needs of mineral and energy resources emphasize impact of human activities. The planetary view of our Earth as a deeply complex interconnected system also emphasizes the need of international scientific cooperation. International collaboration presents an immense potential and is urgently needed for further development of geosciences research and education. In analyzing international collaboration a relevant aspect is the role of scientific societies. Societies organize meetings, publish journals and books and promote cooperation through academic exchange activities and can further assist communities in developing countries providing and facilitating access to scientific literature, attendance to international meetings, short and long-term stays and student and young researcher mobility. Developing countries present additional challenges resulting from limited economic resources and social and political problems. Most countries urgently require improved educational and research programs. Needed are in-depth analyses of infrastructure and human resources and identification of major problems and needs. Questions may include what are the major limitations and needs in research and postgraduate education in developing countries? what and how should international collaboration do? and what are the roles of individuals, academic institutions, funding agencies, scientific societies? Here we attempt to examine some of these questions with reference to case examples and AGU role. We focus on current situation, size and characteristics of research community, education programs, facilities, economic support, and then move to perspectives for potential development in an international context.

UNIVERSITY INTERNATIONAL COOPERATION AS A MEANS FOR REGIONAL INTEGRATION AND DEVELOPMENT

Directory of Open Access Journals (Sweden)

Viktoriia DONCHENKO

2015-10-01

Full Text Available Programs of international cooperation in higher education claim to promote peace and intercultural understanding, contribute to development of efficient human resources as well as research and innovation. For centuries, universities were centers of progress that ensure community’s development. Processes of globalization, internationalization, rapid development of information technology transform the mission of university, challenging modern universities to join forces to meet growing needs of knowledge society. The European Higher Education Area is continuously working to reduce mismatch of skills between the workforce and labor market. International cooperation in education has fundamental potential for reducing economic disparity. Ukrainian government views higher education as a means of growth and development and considers international activity pivotal in responding to global and regional change and achieving world quality standards of education. The aim of this paper is to explore potential of international cooperation in higher education in globalized world by examining selected international projects and their outcomes.

International trade drives biodiversity threats in developing nations.

Science.gov (United States)

Lenzen, M; Moran, D; Kanemoto, K; Foran, B; Lobefaro, L; Geschke, A

2012-06-06

Human activities are causing Earth's sixth major extinction event-an accelerating decline of the world's stocks of biological diversity at rates 100 to 1,000 times pre-human levels. Historically, low-impact intrusion into species habitats arose from local demands for food, fuel and living space. However, in today's increasingly globalized economy, international trade chains accelerate habitat degradation far removed from the place of consumption. Although adverse effects of economic prosperity and economic inequality have been confirmed, the importance of international trade as a driver of threats to species is poorly understood. Here we show that a significant number of species are threatened as a result of international trade along complex routes, and that, in particular, consumers in developed countries cause threats to species through their demand of commodities that are ultimately produced in developing countries. We linked 25,000 Animalia species threat records from the International Union for Conservation of Nature Red List to more than 15,000 commodities produced in 187 countries and evaluated more than 5 billion supply chains in terms of their biodiversity impacts. Excluding invasive species, we found that 30% of global species threats are due to international trade. In many developed countries, the consumption of imported coffee, tea, sugar, textiles, fish and other manufactured items causes a biodiversity footprint that is larger abroad than at home. Our results emphasize the importance of examining biodiversity loss as a global systemic phenomenon, instead of looking at the degrading or polluting producers in isolation. We anticipate that our findings will facilitate better regulation, sustainable supply-chain certification and consumer product labelling.

Emerging Trends in Development of International Information Security Regime

Directory of Open Access Journals (Sweden)

Elena S. Zinovieva

2016-01-01

Full Text Available The article discusses the key trends shaping the international regime on information security. International cooperation in this area at the global level encounters contradictions of state interest. The main actors of the information security are the United States, Russia, China and the EU countries (Britain, France and Germany. The main contradiction is developing between the US on one side and Russia and China on the other. EU countries occupy the middle position, gravitating to that of US. The article proves that international cooperation on information security will reflect the overall logic of the development of international cooperation, which is characterized by a new model of cooperation, with the participation of state and non-state actors, known as multi-stakeholder partnerships and multi-level cooperation. The logic of the formation of an international regime on information security is closest to the logic of the formation of the international non-proliferation regime. It is in the interest of Russia to support the trend towards regionalization of information security regime. Russia can form a regional information security regime in the former Soviet Union on the basis of the CSTO and SCO and potentially on a wider Eurasian space. Such regional regime would give Russia an opportunity to shape the international regime and closely monitor emerging information security issues in the former Soviet Union, and remove the potential threat of "color revolutions".

The US Department of Energy (DOE) and the Nuclear Energy Agency of the Organization for Economic Cooperation and Development/Nuclear Energy Agency (OECD/NEA) began to act on their recognition of the importance of education in nuclear literacy, specifically in radioactive waste management (RWM), several years ago. To address this Goal for nuclear literacy, the US DOE; through the Information and Education Division of the Office of Civilian Radioactive Waste Management (OCRWM) and in cooperation with the OECD/NEA, organized an ''International Workshop on Education in the Field of Radioactive Waste Management'' in Engelberg, Switzerland in June of 1991. To this end, a grant to support nuclear literacy and RWM was written and funded by the OCRWM and the education division of the DOE Yucca Mountain Office in 1990. The over-riding Goal of that workshop and the DOE grant was to find ways of raising the level of nuclear literacy in the general public through educational programs in radioactive waste management (RWM). The two Main Objectives of the workshop were: first, to contribute to an information base for education systems, on global aspects of radioactive waste management; and second, to achieve international consensus on the basic tools and methods required to develop the information base. These two objectives also became the principal objectives of the DOE International Workshops grant. In other words, the global and local (Nevada) objectives were one and the same. Workshop overviews and accomplishments are summarized in this report

Numerical investigation of the reactor pressure vessel behaviour under severe accident conditions taking into account the combined processes of the vessel creep and the molten pool natural convection

International Nuclear Information System (INIS)

Loktionov, V.D.; Mukhtarov, E.S.; Yaroshenko, N.I.; Orlov, V.E.

1999-01-01

Analysis of the WWER lower head behaviour and its failure has been performed for several molten pool structures and internal overpressure levels in a reactor pressure vessel (RPV). The different types of the molten pools (homogeneous, conventionally homogeneous, conventionally stratified, stratified) cover the bounding scenarios during a hypothetical severe accident. The parametric investigations of the failure mode and RPV behaviour for various molten pool types, its heights and internal overpressure levels are presented herein. A coupled treatment in this investigation includes: (i) a 2-D thermohydraulic analysis of a molten pool natural convection. Domestic NARAUFEM code has been used in this detailed analysis for prediction of the heat flux from the molten pool to the RPV inner surface; and (ii) a detailed 3-D transient thermal analysis of the RPV lower head. Domestic 3-D ASHTER-VVR finite element code has been used for the numerical simulations of the high temperature creep and failure of the lower head. The effect of an external RPV cooling, temperature-dependent physical properties of the molten pool and vessel steel, the hydrostatic forces and vessel dead-weight were taken into account in this study. The obtained results show that lower head failure occurs as a result of the vessel creep process which is significantly dependent on both an internal overpressure level and the type of molten pool structure. In particular, it was found that there were combinations of 'overpressure-molten pool structure' when the vessel failure started at the 'hot' layers of the vessel. (orig.)

Probabilistic fracture mechanics analysis of boiling water reactor vessel for cool-down and low temperature over-pressurization transients

Energy Technology Data Exchange (ETDEWEB)

Park, Jeong Soon; Choi, Young Hwan; Jhung, Myung Jo [Safety Research Division, Korea Institute of Nuclear Safety, Daejeon (Korea, Republic of)

2016-04-15

The failure probabilities of the reactor pressure vessel (RPV) for low temperature over-pressurization (LTOP) and cool-down transients are calculated in this study. For the cool-down transient, a pressure-temperature limit curve is generated in accordance with Section XI, Appendix G of the American Society of Mechanical Engineers (ASME) code, from which safety margin factors are deliberately removed for the probabilistic fracture mechanics analysis. Then, sensitivity analyses are conducted to understand the effects of some input parameters. For the LTOP transient, the failure of the RPV mostly occurs during the period of the abrupt pressure rise. For the cool-down transient, the decrease of the fracture toughness with temperature and time plays a main role in RPV failure at the end of the cool-down process. As expected, the failure probability increases with increasing fluence, Cu and Ni contents, and initial reference temperature-nil ductility transition (RTNDT). The effect of warm prestressing on the vessel failure probability for LTOP is not significant because most of the failures happen before the stress intensity factor reaches the peak value while its effect reduces the failure probability by more than one order of magnitude for the cool-down transient.

In Korea, for the export of nuclear energy system and the increase of international credibility and transparence of domestic nuclear system and fuel cycle development, the independent development of PR evaluation methodology was started in 2007 as a nuclear long term R and D project and the development is being performed for the model of PR evaluation methodology. In 1st year, comparative study of GEN-IV/INPRO, PR indicator development, quantification of indicator and evaluation model development, analysis of technology system and international technology development trend had been performed. In 2nd year, feasibility study of indicator, allowable limit of indicator, review of technical requirement of indicator were done. The results of PR evaluation must be applied in the beginning of conceptual design of nuclear system. Through the technology development of PR evaluation methodology, the methodology will be applied in the regulatory requirement for authorization and permission to be developed

A perspective on the recent developments in international financial reporting

OpenAIRE

Dima (Cristea), Stefana Maria; David, Delia; Păiuşan, Luminiţa

2010-01-01

The objective of the present paper is to provide a synopsis of the recent international financial reporting developments as well as to identify some of the related worldwide implications. The unprecedented joint activity of the International Accounting Standards Board (IASB) and US Financial Accounting Standards Board (FASB) has caused, in the last decade, a series of debates on whether or not International Financial Reporting Standards (IFRSs) represent what is best of the international acco...

The Development of International Programs in a School of Social Work

Directory of Open Access Journals (Sweden)

Frank B. Raymond

2014-04-01

Full Text Available During the last decade increasing numbers of schools of social work have adopted an international mission and have developed a variety of activities to reflect their global perspective. In earlier years, however, relatively few schools expressed a global mission, offered coursework on international social work, provided field placements or other opportunities to expose students to international learning, or extended components of their academic programs to other countries. An early leader in doing such things was the College of Social Work at the University of South Carolina (COSW, where the author was privileged to serve as dean for 22 years (1980-2002 when many of these developments occurred. This paper will discuss how this school acquired an international mission and developed various programs to manifest this commitment. The paper will describe, in particular, the college’s signature achievement in international social work education – the development and implementation of a Korea-based MSW program. The COSW was the first school of social work in the US to offer a master’s degree in its entirety in a foreign country. It is hoped that the recounting of this school’s experiences will offer guidance to other social work education programs that are exploring ways of expanding their international initiatives.

Development Education and Education in International Development Policy: Raising Quality through Critical Pedagogy and Global Skills

Directory of Open Access Journals (Sweden)

Amy Skinner

2013-11-01

Full Text Available Development education is an approach to learning that questions dominant paradigms of development and inspires citizen- and community-driven change towards a world of greater social justice. This article provides an overview of development education and reflects on the extent to which development education principles are currently reflected in, or missing from, mainstream educational policies pursued within an international development framework. In particular, the article addresses the issue of quality in education – one of the key current debates within international education policy – and suggests that, through its critical pedagogy and focus on the development of global skills, development education has a significant contribution to make to these debates. The article suggests that greater collaboration between the field of development education and international education policy could facilitate the creation of an agenda that focuses on education quality and learning processes, as opposed to the current preoccupation with education access and outcomes.

Background and perspective on rapid progress and deepening of international development of nuclear industry-composition of international nuclear energy business 'cooperation and competition'

Kano, Tokio; Kanda, Keji; Ishizuka, Nobuo

2005-01-01

Based on the recognition that international development of nuclear industry was important by a viewpoint of international cooperation to neighboring Asian area and also it was the trump that defeated a feeling of domestic confinement, the Japan Atomic Industrial Forum (JAIF) founded Nuclear energy international development gathering' in November 2004. On that occasion our magazine (March, 2005 issue) featured 'prospects and problem of the international development of nuclear energy use'. Slightly for half a year afterwards this nuclear energy international development has been rapidly deepened and become a close-up as a policy of an important strategy of the field of nuclear energy that the government and the private sector were united to make. Therefore the nuclear energy international development was secondly featured from multidirectional points of view such as a background of nuclear energy international development, composition of international nuclear energy business, a main strategy of three makers, approach of finance / a business firm.

International Organizations: the Main Factors of Emergence and Development

Directory of Open Access Journals (Sweden)

Lev S. Voronkov

2015-01-01

Full Text Available The author argues that the emergence of the first permanent intergovernmental (IIGO and non-governmental (INGO organizationsin the second half of the XIX-th century was due to common causes. He tries to justify the need to consider them not as independent objects of study, but as the phenomenon, caused by the high level of internationalization of economic life of states and of socio-economic consequences of the industrial revolution, reached in this period. The emergence of IIGOs, based on international treaty, was accompanied by establishment of a large number of INGOs operating in similar fields of human activity, which performed supplementary functions and regulated areas of cooperation and public needs, not covered by interstate agreements. The article presents the main factors that in later stages of internationalization and development of contemporary international relations gave the impetus to emergence and development of international organizations, including the military-technological revolution, that gave birth to mass destruction weapons and avalanche-like growth of the number of human and material losses during wars and military conflicts, the Cold War between world communism and world capitalism, the collapse of the colonial system and formation ofa new main contradiction of the world politics between the "Club of rich countries" and states of the "global periphery", beginning of development of regional integration processes and, finally, the emergence of global problems. The article emphasizes that both IIGOs and INGOs evolved from the supportive tools in implementation of multilateral interaction of sovereign states towards becoming an integral part of contemporary international relations, fulfilling many vital functions of modern human society and its citizens. Given the involvement of the overwhelming majority of modern sovereign states and tens of thousands of civil society organizations in activity of numerical IIGOs and INGOs

A schedule for fusion research development and international collaboration

International Nuclear Information System (INIS)

Kakihana, H.

1983-01-01

In order to reach their goal of commercial fusion power reactors, development must proceed in a series of basic stages. Each step is expected to incur an increased level of cost. The cost-sharing benefits of international collaboration will become increasingly important and attractive with each successive step preceding commercialization. Outstanding examples of implementation of international collaboration in fusion include the JET project and the INTOR workshop which lend encouragement for the prospects for international collaboration in fusion in the future.

Development of coal international trade

Energy Technology Data Exchange (ETDEWEB)

1983-11-01

Most of the coal produced today is still for domestic consumption but international trade will grow in the future. This development requires investments and time for the realization of terminals, means of transport and preparation. Problems of land and sea transport and their influence on cost are examined. Environmental problems are briefly evolved. Charges, ship size, capacity are given for 1983/84 and estimated for 1987/90 in tables for main exporting countries (Australia, Canada, South Africa, USA and South America) and for importing European countries.

The relationship between disarmament and development in the current international context

International Nuclear Information System (INIS)

2005-01-01

The report of the Group of Governmental Experts provides a reappraisal of the disarmament-development relationship and the role of the Organization in this connection, taking into account all the major international changes that have taken place since the adoption of the Final Document of the International Conference on the Relationship between Disarmament and Development in 1987. In particular, the review dwells on the pivotal role of security, the costs and consequences of military expenditure, the release of resources for development, the importance of multilateralism and the role of the United Nations, as well as other international organizations and institutions. The report makes numerous recommendations. Notably, it calls for mainstreaming the disarmament-development relationship; raising awareness of this relationship within the international community; engaging in a wide range of conflict-prevention measures, including those related to illicit small arms and light weapons; promoting security through greater openness, transparency and confidence; and strengthening further the role of the United Nations and other international institutions, as well as the donor community, towards these ends. The recommendations also include specific topics for further research by specialized United Nations bodies and non-governmental organizations in order to enhance understanding of the relationship between disarmament and development

It is significant to internationally develop the nuclear power plants technology that has been fostered by Japan's nuclear industry. It is also important to work with taking the degree of development of nuclear power plants of the recipient country into consideration. ''Forum on International Development of Nuclear Industry'' organized by the Japan Atomic Industrial Forum, Inc. (JAIF) proposed it would be indispensable for a Japan's nuclear industry to establish a Japan-U.S. Cooperation with the support of Government in order to develop the nuclear technology internationally. In November 2005, the investigating team including utilities and nuclear industry visited U.S. and exchanged opinions on its possibility. Investigating results and their evaluation were described.

Adductor spasmodic dysphonia (AdSD) is a voice disorder characterized by variable symptom severity and voice disability. Those with the disorder experience a wide spectrum of symptom severity over time, resulting in varied degrees of perceived voice disability. This study investigated the longitudinal variability of AdSD, with a focus on auditory-perceptual judgments of a dimension termed laryngeal overpressure (LO) and patient self-assessments of voice-related quality of life (V-RQOL). Longitudinal, correlational study. Ten adults with AdSD were followed over three time periods. At each, both voice samples and self-ratings of V-RQOL were gathered prior to their scheduled Botox injection. Voice recordings subsequently were perceptually evaluated by eight listeners for LO using a visual analog scale. LO ratings for all-voiced and Rainbow Passage sentence stimuli were found to be highly correlated. However, only the LO ratings obtained from judgments of AV stimuli were found to correlate moderately with self-ratings of voice disability for both the physical functioning and social-emotional subscores, as well as the total V-RQOL score. Based on perceptual judgments, LO appears to provide a reliable means of quantifying the severity of voice abnormalities in AdSD. Variability in self-ratings of the V-RQOL suggest that perceived disability related to AdSD should be actively monitored. Further, auditory-perceptual judgments may provide an accurate index of the potential impact of the disorder on the speaker. Similarly, LO was supported as a simple clinical measure that serves as a reliable index of voice change over time. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Development of the individual agencies within international organizations: comparative-personological view

Directory of Open Access Journals (Sweden)

Т. О. Калмиков

2015-05-01

Full Text Available Problem setting: Personalized activity of individuals holding offices of individual organs in the structure of international organizations is an essential part of the activities of these organizations. Meanwhile, today legal science researches this problem mainly in the context of the development of separate branches of international law. Recent research and publications analysis: From Max Weber, the development of individual organs was studied as a question how one transforms institutions that are led by high-profile individuals into institutions that have a life and energy of their own". Current international legal research in this regard provided by  H. H. Koh, F. Benua-Romer, H. Klebes, R. Kicker and the others. There are no relevant Ukrainian legal studies on this issue today. Paper objective: The purpose of the article is to review the issue on the example of a relatively new international bodies - the UN High Commissioner for Human Rights and the Commissioner for Human Rights of the Council of Europe. The features of organs, crucial for the study are: the features of appointment (election of candidate, term of his office and special activities scheduled for each of these positions. Paper main body: Comparing the Institute of the High Commissioner and the Commissioner for Human Rights of the Council of Europe in personological view, we note that the personal characteristics and expert practices of the first, second and third Council of Europe Commissioner largely matches with the same first three (in same order United Nations High Commissioners for Human Rights. This fact suggests that the election of candidates for these positions is a part of strategic transformation of the body. There is a reason to believe that the strategy of the international organizations, not only related to their desire to be effectively involved in actions within their mandate, but also with the desire to increase their influence in comparison with the

China's Approach to International Development: A Study of Southeast Asia

Directory of Open Access Journals (Sweden)

Neil Renwick

2015-12-01

Full Text Available China is establishing itself as a new international aid donor. This study explains China's emerging approach to international development assistance. The paper addresses the question of how far China's understanding of "development" is an appropriate basis for genuinely "win-win" relationships? The paper explores this question by examining China's relationship with Southeast Asia. China is re-emphasising its commitment and partnership credentials with neighbouring states, some of whom have many people living in poverty and as countries are in need of development assistance. The paper identifies key facets of China's approach to international development, examines economic, political and strategic factors underpinning China's approach in Southeast Asia. Adopting a Human Security perspective, it assesses China's development contribution with reference to Cambodia, Laos and Myanmar and highlights popular opposition. The study finds that Chinese trade and investment are making a significant contribution to the region's economic growth. However, the analysis identifies two problems in China's approach, an over-reliance on the level of state-to-state relations and too narrow a domain of engagement centred upon economic cooperation. China needs to incorporate a societal engagement strategy highlighting transparency and accountability of Chinese corporate behaviour. It also needs to re-balance its approach by emphasising human capital capability and capacity-building across the non-economic social and cultural domains. China's approach to international development is a rapid learning process and is emerging, but still has further to go.

Development of a definitive internal dosimetry code

International Nuclear Information System (INIS)

Miller, G.; Inkret, W.C.; Schillaci, M.E.

1996-01-01

Internal dosimetry may be divided into tow main problems: (1) the forward (scientific) problem of determining biokinetics models that describe how radionuclides are taken into the body, distributed in body tissues, and excreted, and (2) the inverse (mathematical) problem: given the measured amounts in excreta and assuming a biokinetic model, to determine the times and amounts of intakes into the body. The inverse problem of internal dosimetry is, in fact, a generic problem studied in other fields (e.g., image reconstruction, spectral deconvulution, and model parameter fitting). We have developed a code for plutonium internal dosimetry using the maximum entropy method, a method for solving underdetermined inverse problems with a positivity constraint. Within the framework of Bayesian statistics, we believe the definitive approach is to examine the Bayesian posterior probability describing the probability of an intake scenario (X i ) read ( ... ) as open-quotes the set of,close quotes where X i denotes the intake amount that occurs on the with day. For plutonium, for a worker with a long employment history, this is a very high dimensional probability space, since there may be on the order of 10,000 days when intakes may have occurred. Within this high dimensional space, we calculate the mean intake scenario as i > where denotes the expectation value over the posterior probability distribution. Similarly, we calculate uncertainties and other relevant quantities, such as X 2 , as expectation values over the posterior distribution. Thanks to a recent breakthrough in describing the mathematical structure of the intake process (a Poisson sum representation of intakes), we have developed the initial version of a Bayesian expectation-value algorithm for internal dosimetry reconstructions

Globalization And Its Influence On The Development Of International Law

Directory of Open Access Journals (Sweden)

Olga M. Mesheriakova

2014-09-01

Full Text Available In the present article author researches questions of globalization impact on the international law. Author notes that today it is possible to talk about the new phase of globalization that is associated with the development of bilateral regional agreements, as well as changes in the configuration of the trade and political landscape. In the article author also reveals the essence of processes that determine development of international law in the century of globalization. Along with the formation of a new branch of law - integration law, which is a kind of legal mechanism to govern global public relations, development of modern public law is determined by the changing of nature of production and international specialization, as well as multinational corporations. In the conclusion author points out possibility of the own monetary system creation in the integration community, even in the format of multi-speed integration, what allows EU member states together confront to dollar and yuan, what contributes to the achievement of their national interests in the economic sphere, therefore, legal mechanism established the European Union takes into account both regional and economic aspects that are associated with the process of globalization. With new trends in the development of modern international law it is necessary to develop advanced models of legal regulation for processes caused by globalization.

Previous studies on shock overpressure and drag events have provided analytical predictions, but they are not sufficient to explain ejection of liquid from the tank. This study focuses on the hydrodynamic behavior of the liquid after collision to explain subsequent ejection of liquid. The study is characterized by use of high-velocity projectiles and analysis of projectile dynamics in terms of energy loss to tank contents. New tests were performed at two projectile velocities (963 and 1255 m s(-1)) and over a range of viscosities (from 1 to 23.66 mPa s) of the target liquid. Based on data obtained from a high-speed video recorder, a phenomenological description is proposed for the evolution of intense pressure waves and cavitation in the target liquids.

As a result, data demonstrate that national economic development depends on the participating of the countries to globalization processes at regional and international levels.

INTERNATIONAL RESERVES, GUARANTEE THAT SUPPORTS ROMANIA'S ECONOMIC DEVELOPMENT

Directory of Open Access Journals (Sweden)

MEDAR LUCIAN-ION

2014-10-01

Full Text Available Aggregate demand in our country far exceeds the ability of the economy to produce goods and services. The gap between total demand for goods and services on the one hand and economic status, on the other hand stands out primarily by the continuing need for funds to cover the budget deficit. The Lack of foreign investors, poor development of capital market and non-involvement of credit institutions to support economic development leads the Romanian state to borrow regularly on international money market. Guarantor of the country for these loans is the reserve fund managed by the central bank of the state. Trade deficits and foreign borrowing are two components of the same problems. As the state borrows more from the international financial markets the higher is the trade deficit. A national initiative on facilities development companies with export production and aggregate demand for domestic products, can lead to lower imports. Increasing the fund's reserves and activation may be one of the solutions required to support economic development. Through this study we try to discover the role of the reserve fund and other sources of economic development.

Full Text Available This study analyzes the effects of institutional structure on the international competitiveness of developed countries econometrically by employing a “Panel Data Analysis” with a sample of 21 developed countries and 23 institutional variables for the period 2000-2011. The results of the analysis indicate that while judicial independence, protection of intellectual property rights, integrity of the juridical system, marginal tax, political freedoms, black market exchange rate, restrictions on foreign investment, private sector’s share in the banking system, hiring-minimum wage, and hiring-dismissal have a positive effect; the nature of legal arrangements, government spending, transfers and subsidies, civil liberties, tariffs, regulations regarding trade barriers, collective bargaining, and military tutelage have a negative effect on the international competitiveness of developed countries.

Managing the development of plant subsystems for a large international project

International Nuclear Information System (INIS)

Gurd, D.

2012-01-01

ITER is an international collaborative project under development by nations representing over one half of the world's population. Major components will be supplied by 'Domestic Agencies' representing the various participating countries. While the supervisory control system, known as CODAC, will be developed 'in fund' by the International Organization at the project site in the south of France, the EPICS and PLC-based plant control subsystems are to be developed and tested locally, where the subsystems themselves are being built. This is similar to the model used for the development of the Spallation Neutron Source, which was a US national collaboration. However the much more complex constraints of an international collaboration preclude the use of many specifics of the SNS collaboration approach. Moreover, procedures for final system integration and commissioning at ITER are not yet well defined. This paper will outline the particular issues either inherent in an international collaboration or specific to ITER, and will suggest approaches to mitigate those problems with the goal of assuring a successful and timely integration and commissioning phase.

Social Protection as Development Policy: A New International Agenda for Action

Directory of Open Access Journals (Sweden)

François-Xavier Merrien

2013-06-01

Full Text Available At the turn of the millennium, social protection became a new priority for both states of the global South and international development policy more generally. As, in the past, social protection policies were considered unsuitable for development countries, the elevation of social protection to the level of a preferred instrument of development marks a fundamental paradigm shift. This shift began in the late 1990s, driven by disenchantment with the results of economic adjustment programmes, the 1997 Asian economic crisis, and a heightened awareness of the negative effects of global poverty. Social protection thus became a preferred instrument of the Millennium Development Goals, while the World Bank promoted social protection as a key component of international poverty reduction strategies (social risk management. The Department for International Development (DfID in the United Kingdom, along with other organisations, promoted a development model centred on the rights of the poor. Successful social protection programmes developed in the Global South – such as Brazilian and South African social pension schemes and conditional cash transfers (CCT established in Mexico and Brazil – were adopted as model programmes at the global level. The purpose of this article is to analyse the emergence of social protection in development policies. From this perspective, it examines the various types of programmes promoted by the international community, with a specific focus on CCT. It concludes with an assessment of the relative appropriateness of social protection policies for developing countries.

Development of an International Electric Cooperative Initiative on Energy Efficiency

Energy Technology Data Exchange (ETDEWEB)

Paul Clark; David South

2004-05-01

NRECA conceived of the International Electric Cooperative Initiative on Energy Efficiency (IECIEE) in order to provide an ongoing means of contributing voluntary actions on greenhouse gas emissions mitigation as an integral component of its international programs and projects. This required designing the IECIEE to be integrated directly with the core interests and attributes of participating cooperatives in the U.S. and Latin America, which was the initial focus area selected for the IECIEE. In the case of NRECA International, the core interests related to promoting and strengthening the electric cooperative model, which has proved highly successful in maximizing operational efficiencies in electric power generation, distribution and retailing, as compared to government-owned entities. The approach involved three basic components: (i) establishing the IECIEE mechanism, which involved setting up a functioning organizational vehicle providing for investment, management, and emissions credit accounting; (ii) developing a portfolio of projects in countries where NRECA International could effectively implement the broader mandate of cooperative development as energy efficient suppliers and distributors of electrical energy; and (iii) conducting outreach to obtain the commitment of participants and resources from U.S. and Latin American cooperatives and partnering agencies in the development financing community.

Status of international HTGR development

International Nuclear Information System (INIS)

Homan, F.J.; Simon, W.A.

1988-01-01

Programs for the development of high-temperature gas-cooled reactor (HTGR) technology over the past 30 years in eight countries are briefly described. These programs have included both government sector and industrial sector participation. The programs have produced four electricity-producing prototype/demonstration reactors, two in the United States, and two in the Federal Republic of Germany. Key design parameters for these ractors are compared with the design parameters planned for follow-on commercial-scale HTGRs. The development of HTGR technology has been enhanced by numerous cooperative agreements over the years, involving both government-sponsored national laboratories and industrial participants. Current bilateral cooperative agreements are described. A relatively new component in the HTGR international cooperation is that of multinational industrial alliances focused on supplying commercial-scale HTGR power plants. Current industrial cooperative agreements are briefly discussed

Development of glia and blood vessels in the internal capsule of rats.

Science.gov (United States)

Earle, K L; Mitrofanis, J

1998-02-01

We have explored two aspects of internal capsule development that have not been described previously, namely, the development of glia and of blood vessels. To these ends, we used antibodies to glial fibrillary acidic protein (GFAP) and to vimentin (to identify astrocytes and to radial glia) and Griffonia simplicifolia (lectin; to identify microglia and blood vessels). Further, we made intracardiac injections of Evans Blue to examine the permeability of this dye in the vessels of the internal capsule during neonatal development. Our results show that large numbers of radial glia, astrocytes and microglia are not labelled with these markers in the white matter of the internal capsule until about birth; very few are labelled earlier, during the critical stages of corticofugal and corticopetal axonal ingrowth (E15-E20). The large glial labelling in the internal capsule at birth is accompanied by a dense vascular innervation of the capsule; as with the glia, very few labelled patent vessels are seen earlier. After intracardiac injections of Evans Blue, we find that the blood vessels of the internal capsule are not particularly permeable to Evans Blue. At each age examined (P0, P5, P15), blood vessels are outlined very clearly and there is no diffuse haze of fluorescence within the extracellular space, which is indicative of a leaky vessel. There are three striking differences between the glial environment of the internal capsule and that of the adjacent thalamus. First, the internal capsule is never rich with radial glial fibres (vimentin- and GFAP-immunoreactive) during development (except at P0), whereas the thalamus has many radial fibres from very early development (E15-E17). Second, astrocytes (vimentin- and GFAP-immunoreactive) first become apparent in the internal capsule (E20-P0) well before they do in the thalamus (P15). Third, the internal capsule houses a large transient population of amoeboid microglia (P0-P22), whereas the thalamus does not; only ramified

Development of international labor migration in the dynamics of globalization processes

Directory of Open Access Journals (Sweden)

Rubinskaya Eteri, D.

2015-03-01

Full Text Available The current characteristics of international migration caused by the qualitative changes that occur in the global economy under influence of increasing globalization. The paper attempts to suggest periodization of the global economy development and to identify features of international labor migration occurred under the influence of deep changes in the world economy. During this period, the author identifies three stages in the formation of globalization, the transition criterion from one to other is the degree of world economy changes under the influence of the productive forces development and the major social and political transformations resulted in qualitative changes in the processes of international labor migration. At the same time in the context of globalization the place and role of international labor migration changes in the global economy system: migration becomes a means of promoting the globalization of countries and regions, the most important factor of demographic development and economic growth.

On the study of petroleum system operation: contribution of a two-dimensional modeling; Contribution a l`etude du fonctionnement des systemes petroliers: apport d`une modelisation bi-dimensionnelle

Energy Technology Data Exchange (ETDEWEB)

Burrus, J

1997-07-10

The aim of the thesis is to validate concepts used in hydrocarbon generation and migration models; the model considered is the Temispack model developed by IFP, and the validation is based on the investigation of the thermal and hydraulic evolution in various sedimentary basins. It is shown that, in general, the thermal history of sediments is influenced by external processes (sedimentation rates, lithology, climate changes, regional-scale groundwater circulations) which frequently overprint internal processes (variations of crustal/mantle heat flow). It is found that external processes can frequently explain past thermal events that were erroneously attributed to internal causes (tectonic-thermal events). The origin of over-pressures in young basins with high sedimentation rates is shown to be generally related to compaction disequilibrium. Shale permeability values calibrated against overpressure profiles are consistent with experimental constraints. Compaction models predict too-high porosity in over-pressured sediments; this inconsistency is shown to be related to an inadequate definition of the Biot coefficient. In intracratonic basins with low sedimentation rates, diagenesis and fracturing are responsible for the large variability of shale permeability. Hydrocarbon generation models based on Arrhenius kinetics, and kinetic parameters calibrated on Rock Eval pyrolysis experiments are shown to be consistent with observations. Hydrocarbon expulsion and migration can be approximated by a multiphase Darcy equation using pseudo relative permeabilities. Migration pathways are shown to be very sensitive to the stratigraphic organization of basins. The volume 1 presents a bibliographical review, the Temispack model, and the geodynamics of a passive-type margin, the Gulf of Lion

Study by similarity of wind influence on mass transfers in complex buildings; Etude par similitude de l'influence du vent sur les transferts de masse dans les batiments complexes

Energy Technology Data Exchange (ETDEWEB)

Le Roux, Nicolas

2011-12-05

Residential and industrial buildings equipped with a ventilation system are complex facilities, where various heat and mass transfers could occur according to the operating conditions. In order to study these mass transfers, a methodology has been developed so as to carry out reduced-scale experiments for the study of isothermal flows, in steady or transient state. This methodology has been numerically and experimentally validated on simple configurations, and then applied to two standard configurations, representing nuclear facilities. The wind influence on mass transfers inside these configurations, in normal, damaged (stopping ventilation) or accidental (internal overpressure) situations, has been studied in the Jules Verne climatic wind tunnel of the CSTB. The wind effects, coupled or not with an internal overpressure, can lead to a partial or a total loss of the pollutant's containment inside buildings. Moreover, the wind turbulence can bring about instantaneous reversal leakage flow-rates, which cannot be identified in steady state. In addition, the study of transient phenomena has highlighted the low influence of the branch inertia on transient flows, for typical values of real facilities. Finally, tracer tests have been carried out in order to study the pollutant dispersion inside a standard configuration subjected to wind, mechanical ventilation and internal overpressure effects. The reliability of the zonal code SYLVIA, used notably to support safety assessment in nuclear buildings, has been analyzed from these experimental results. The modelling of the physical phenomena experimentally observed has been validated, in steady and transient states. However, limitations have been identified for the study of pollutant dispersion, due to hypothesis used in SYLVIA code, as in all zonal codes (homogenous concentration inside rooms, instantaneous propagation inside branches and rooms).

[International conference on population and development in Cairo].

Science.gov (United States)

van Enk, A

1994-11-05

The UN Conference on Population and Development was held in Cairo in September 1994, and dealt with a range of sensitive issues that were eventually recorded in an action program. In addition, a sort of shadow conference was also held by various organizations. The precedents of this conference were the conferences held in Bucharest in 1974, which stressed the world crisis and population explosion, and in Mexico in 1984, where the first signs of the slackening of population growth induced less emphasis on family planning programs and more on the status of women. At Cairo again a crisis atmosphere reigned because rapid population growth has not been followed by rapid development. Birth control discussions also focused on ethical and religious norms, human rights, and emancipation problems. Most of all, the sustainability of development programs was stressed. Global decline of mortality combined with a continuing high birth rate has resulted in a population growth of 3% or more. In the course of 40 years the growth was 46% in industrialized countries as compared to 161% in the poorest lands. The total world population has reached 5 billion, of which only 20% live industrial countries. The influence of the AIDS epidemic on the demographic figures is not likely to be as much as anticipated a few years ago. Other problems are demographic aging, population decline (a below replacement fertility rate in Japan, Spain, and Italy), and uncontrolled internal and international migration (refugees in developing countries and flight to major cities). In the next 30 years almost two-thirds of the population of developing countries will be living in shabby, sprawling megacities. In 1989, in preparation for the Cairo conference, an international forum was held in Amsterdam on population. It dealt with the reproductive rights of women, the negative impact of structural readjustment programs on family planning, and the priority of women's education.

At a brewery, the base plate-to-shell weld seam of a 90-m3 vertical cylindrical steel tank failed catastrophically. The 4 ton tank “took off” like a rocket leaving its contents behind, and landed on a van, crushing it. The top of the tank reached a height of 30 m. The internal overpressure responsible for the failure was an estimated 60 kPa. A rupture disc rated at <50 kPa provided overpressure protection and thus prevented the tank from being covered by the European Pressure Equipment Dir...

Integrating development and climate policies: National and international benefits

NARCIS (Netherlands)

Kok, M.; Metz, B.; Verhagen, J.

2008-01-01

What lessons for policy makers at national and international level can be drawn from the growing experiences of reconciling development and climate change? The key to achieving this is to approach the problem from the development perspective, since that is where in most countries the priority lies.

The Transformation of International NGOs and Their Impact on Development Aid

Directory of Open Access Journals (Sweden)

Thomas Richard Davies

2012-03-01

Full Text Available Published by Palgrave MacmillanInternational non-governmental organisations (INGOs are among the key actors in the transformation of development as a global public policy issue in the post-Cold War era. This chapter explores how in the past two decades INGOs concerned with development have transformed their structures and practices as well as development discourse. The author shows how development INGOs have globalised, in terms of both the formation of international confederations and the collaboration of multiple INGOs in global coalitions. A key development has been the erosion of the apparent North–South divide among development INGOs, with INGOs that originated in donor countries reforming their structures to give a greater voice to their affiliates in recipient countries, and organisations that originated in developing countries forming affiliates in developed countries. The reorientation of INGO advocacy from states toward intergovernmental and corporate actors is also explored, as is the creation of new forms of partnerships with both governmental and private actors. The chapter addresses how development INGOs have attempted to respond to critiques of their accountability and legitimacy through reforms such as the International NGO Charter on Accountability, while the conclusion explores the limitations of the transformations of development INGOs, and the challenges that these new configurations pose.

The international development of forensic science standards - A review.

Science.gov (United States)

Wilson-Wilde, Linzi

2018-04-16

Standards establish specifications and procedures designed to ensure products, services and systems are safe, reliable and consistently perform as intended. Standards can be used in the accreditation of forensic laboratories or facilities and in the certification of products and services. In recent years there have been various international activities aiming at developing forensic science standards and guidelines. The most significant initiative currently underway within the global forensic community is the development of International Organization for Standardization (ISO) standards. This paper reviews the main bodies working on standards for forensic science, the processes used and the implications for accreditation. This paper specifically discusses the work of ISO Technical Committee TC272, the future TC272 work program for the development of forensic science standards and associated timelines. Also discussed, are the lessons learnt to date in navigating the complex environment of multi-country stakeholder deliberations in standards development. Crown Copyright © 2018.

THE BASES OF INTERNATIONAL AFFAIRS DEVELOPMENT

Directory of Open Access Journals (Sweden)

DOBRIN IONEL GABRIEL

2014-05-01

Full Text Available Capitalism started as a consequence of the urban phenomena development, as well as of the commercial activities development. Thus, over this period of time, the attitude towards business also changed. This change was based also on certain economic reasons. The term „business” is defined in numerous dictionaries released until the present day in a restrictive and subjective manner, both from the perspective of the totalitarian communist ideology, which happened up to the year 1989, and also from the perspective of the different categories of meanings that were taken into consideration when compiling dictionaries in different international circulation languages. If an enterprise conducts business at an international level, then it will take into consideration the performance of different types of activities which differ greatly from the activities conducted at a national level. All these elements must be carefully studied by the company's management, in order to be able to act with high economic efficiency. It must be said that, in contemporary times, that „invisible hand of the market” from the past is none other than competition. As a consequence of the competitive phenomenon's manifestation, the prices are lower, the services are of a better quality and they are increasingly more diverse. Because of these positive arguments, Adam Smith was named „the father of economy”.

International co-operation in developing the GT-MHR

International Nuclear Information System (INIS)

La Bar, M.P.; Simon, W.A.

1997-01-01

In the Fall of 1995, driven by budget constraints and anti-nuclear sentiments, the US government decided to discontinue financial support of the Gas Turbine-Modular Helium Reactor (GT-MHR). At that time, significant work was underway with participation of several vendors with specialized expertise in various aspects of the GT-MHR. Fortunately the US government provided for documenting the design and development status through an orderly close-out program. Concurrent elimination of government restrictions opened the door for broader international cooperation. Discussion between General Atomics and the Russian Ministry of Atomic Energy (MINATOM), in the summer of 1994, led to an agreement on a jointly funded design and development program for the GT-MHR. The program is initially focused on the burning of weapons plutonium that becomes available from dismantled nuclear weapons. The long term goal is to utilize the same design for commercial applications - using uranium fuel. This program took advantage of existing technologies and facilities in the US and Russia, but right from the beginning left the door open for broader international cooperation. Accordingly, in January 1996, FRAMATOME has joined the ongoing effort. Discussions are underway with other international entities to join this program. The program is proceeding well. Several Russian laboratories/design organizations are participating with GA and FRAMATOME. Significant improvements in the power conversion system design are a clear example of the benefit of the cooperative effort. Further work needs to be done to confirm fuel and components prior to full deployment, etc., providing ample opportunities for international cooperation in many areas

The Co-Development of Parenting Stress and Childhood Internalizing and Externalizing Problems.

Science.gov (United States)

Stone, Lisanne L; Mares, Suzanne H W; Otten, Roy; Engels, Rutger C M E; Janssens, Jan M A M

Although the detrimental influence of parenting stress on child problem behavior is well established, it remains unknown how these constructs affect each other over time. In accordance with a transactional model, this study investigates how the development of internalizing and externalizing problems is related to the development of parenting stress in children aged 4-9. Mothers of 1582 children participated in three one-year interval data waves. Internalizing and externalizing problems as well as parenting stress were assessed by maternal self-report. Interrelated development of parenting with internalizing and externalizing problems was examined using Latent Growth Modeling. Directionality of effects was further investigated by using cross-lagged models. Parenting stress and externalizing problems showed a decrease over time, whereas internalizing problems remained stable. Initial levels of parenting stress were related to initial levels of both internalizing and externalizing problems. Decreases in parenting stress were related to larger decreases in externalizing problems and to the (stable) course of internalizing problems. Some evidence for reciprocity was found such that externalizing problems were associated with parenting stress and vice versa over time, specifically for boys. Our findings support the transactional model in explaining psychopathology.

External-environmental and internal-health early life predictors of adolescent development.

Science.gov (United States)

Hartman, Sarah; Li, Zhi; Nettle, Daniel; Belsky, Jay

2017-12-01

A wealth of evidence documents associations between various aspects of the rearing environment and later development. Two evolutionary-inspired models advance explanations for why and how such early experiences shape later functioning: (a) the external-prediction model, which highlights the role of the early environment (e.g., parenting) in regulating children's development, and (b) the internal-prediction model, which emphasizes internal state (i.e., health) as the critical regulator. Thus, by using data from the NICHD Study of Early Child Care and Youth Development, the current project draws from both models by investigating whether the effect of the early environment on later adolescent functioning is subject to an indirect effect by internal-health variables. Results showed a significant indirect effect of internal health on the relation between the early environment and adolescent behavior. Specifically, early environmental adversity during the first 5 years of life predicted lower quality health during childhood, which then led to problematic adolescent functioning and earlier age of menarche for girls. In addition, for girls, early adversity predicted lower quality health that forecasted earlier age of menarche leading to increased adolescent risk taking. The discussion highlights the importance of integrating both internal and external models to further understand the developmental processes that effect adolescent behavior.

The Current Status and Prospects for Development of International Trade in Goods

Directory of Open Access Journals (Sweden)

Kovtun Tamara D.

2018-03-01

Full Text Available The article is aimed at analyzing the current status and determining prospects for international trade in goods. The dynamics of international trade in goods are characterized and the reasons for its slowdown are disclosed. A considerable attention is paid to the analysis of the commodity and geographical structure of the international trade in goods. On the basis of the conducted research the new tendencies and peculiarities of development of the international trade in goods in the contemporary conditions are disclosed. In particular, the authors consider the tendency of increasing the influence of non-tariff barriers on the dynamics of the international commodity exchange. Based on the calculation of the export quota as an indicator of the intensity of foreign trade in goods, conclusions have been drawn about the degree of openness of national economies in the current conditions. The authors have noted that in the coming years the growth of physical and value volumes of the world commodity exports is projected in the conditions of growth of the world prices for raw products. It has been determined that, most likely, further development of the international trade in goods will take place in conditions of deepening of trade integration at the mega-regional level. An increase in the number of participants in the international trade in goods is also expected in the context of further spread of e-commerce in the developing countries.

Innovative nuclear reactor development. Opportunities for international co-operation

International Nuclear Information System (INIS)

2002-08-01

A number of countries wish to expand their use of nuclear energy or keep open the option of doing so in the future. Any new nuclear generating capacity will be built in the context of increasingly privatized and de-regulated energy markets coupled with heightened public concern over nuclear power. New nuclear power plants must maintain or exceed current levels of safety and must be economically competitive with alternative ways of generating electricity. They must address other challenges as well, among them waste disposal and nonproliferation concerns. This report reviews how some of the innovative nuclear-fission technologies being developed today attempt to address the challenges facing nuclear energy. It suggests some areas for collaborative research and development that could reduce the time and cost required to develop new technologies. The report is a product of the 'Three-Agency Study', a joint project among the International Energy Agency (IEA), the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA).

An international waste convention: measures for achieving sustainable development.

Meyers, Gary D; McLeod, Glen; Anbarci, Melanie A

2006-12-01

Waste is a by-product of economic growth. Consequently, economic growth presents challenges for sustainable resource management and development because continued economic growth implies continued growth in waste outputs. Poor management of waste results in the inappropriate depletion of natural resources and potentially adverse effects on the environment, health and the economy. It is unsustainable. This paper begins by outlining the magnitude of and the current response to the growth in the quantity of waste outputs. This is followed by a consideration of why the international response to date, including the Rio Declaration and Agenda 21, fails to address the issue adequately. The paper concludes with a discussion on why and how an international treaty or other measure could advance sustainable development by providing an appropriate framework within which to address the problem.

Averaging, not internal noise, limits the development of coherent motion processing

Directory of Open Access Journals (Sweden)

Catherine Manning

2014-10-01

Full Text Available The development of motion processing is a critical part of visual development, allowing children to interact with moving objects and navigate within a dynamic environment. However, global motion processing, which requires pooling motion information across space, develops late, reaching adult-like levels only by mid-to-late childhood. The reasons underlying this protracted development are not yet fully understood. In this study, we sought to determine whether the development of motion coherence sensitivity is limited by internal noise (i.e., imprecision in estimating the directions of individual elements and/or global pooling across local estimates. To this end, we presented equivalent noise direction discrimination tasks and motion coherence tasks at both slow (1.5°/s and fast (6°/s speeds to children aged 5, 7, 9 and 11 years, and adults. We show that, as children get older, their levels of internal noise reduce, and they are able to average across more local motion estimates. Regression analyses indicated, however, that age-related improvements in coherent motion perception are driven solely by improvements in averaging and not by reductions in internal noise. Our results suggest that the development of coherent motion sensitivity is primarily limited by developmental changes within brain regions involved in integrating motion signals (e.g., MT/V5.

International sources of financial cooperation for health in developing countries.

Science.gov (United States)

Howard, L M

1983-01-01

By direct consulation and review of published sources, a study of 16 selected official sources of international financial cooperation was conducted over the August 1979 to August 1980 period in order to assess the policies, programs, and prospects for support of established international health goals. This study demonstrated that approximately 90% of the external health sector funds are provided via development oriented agencies. The major agencies providing such assistance concur that no sector, including health, should be excluded "a priori," providing that the requesting nation conveys its proposals through the appropriate national development planning authority. The agencies in the study also were found to be supporting health related programs in all the geographic regions of the World Health Organization (WHO). An associated review of 30 external funding agencies revealed that only 5 reported providing health assistance in more than half of the countries where they provided assistance for general development purposes. Interviewed sources attributed this to the limited manner in which health proposals have been identified, prepared, and forwarded (with national development authority approval) to international agencies. In 1979 concessional development financing totaled approximately US$29.9 billion, US$24.2 billion being provided by 17 major industrial nations, US$4.7 billion by Organization of Petroleum Exporting (OPEC) countries, and less than US$1 billion by the countries of Eastern Europe. Approximately 2/3 of such concessional financing is administered bilaterally, only 1/3 passing through multilateral institutions. UN agencies receive only 12% of these total concessional development financing resources. In 1979, concessional funding for health totaled approximately US$3 billion, approximately 1/10 of which was administered by WHO and its regional offices. It is anticipated that future international funding for health in developing countries will continue

2010-01-01

The 'Research and Development of International Matrix-Solver Prediction System (REDIMPS)' project aimed at improving the TLSE sparse linear algebra expert website by establishing an international grid computing environment between Japan and France. To help users in identifying the best solver or sparse linear algebra tool for their problems, we have developed an interoperable environment between French and Japanese grid infrastructures (respectively managed by DIET and AEGIS). Two main issues were considered. The first issue is how to submit a job from DIET to AEGIS. The second issue is how to bridge the difference of security between DIET and AEGIS. To overcome these issues, we developed APIs to communicate between different grid infrastructures by improving the client API of AEGIS. By developing a server deamon program (SeD) of DIET which behaves like an AEGIS user, DIET can call functions in AEGIS: authentication, file transfer, job submission, and so on. To intensify the security, we also developed functionalities to authenticate DIET sites and DIET users in order to access AEGIS computing resources. By this study, the set of software and computers available within TLSE to find an appropriate solver is enlarged over France (DIET) and Japan (AEGIS). (author)

Developing a prenatal nursing care International Classification for Nursing Practice catalogue.

Science.gov (United States)

Liu, L; Coenen, A; Tao, H; Jansen, K R; Jiang, A L

2017-09-01

This study aimed to develop a prenatal nursing care catalogue of International Classification for Nursing Practice. As a programme of the International Council of Nurses, International Classification for Nursing Practice aims to support standardized electronic nursing documentation and facilitate collection of comparable nursing data across settings. This initiative enables the study of relationships among nursing diagnoses, nursing interventions and nursing outcomes for best practice, healthcare management decisions, and policy development. The catalogues are usually focused on target populations. Pregnant women are the nursing population addressed in this project. According to the guidelines for catalogue development, three research steps have been adopted: (a) identifying relevant nursing diagnoses, interventions and outcomes; (b) developing a conceptual framework for the catalogue; (c) expert's validation. This project established a prenatal nursing care catalogue with 228 terms in total, including 69 nursing diagnosis, 92 nursing interventions and 67 nursing outcomes, among them, 57 nursing terms were newly developed. All terms in the catalogue were organized by a framework with two main categories, i.e. Expected Changes of Pregnancy and Pregnancy at Risk. Each category had four domains, representing the physical, psychological, behavioral and environmental perspectives of nursing practice. This catalogue can ease the documentation workload among prenatal care nurses, and facilitate storage and retrieval of standardized data for many purposes, such as quality improvement, administration decision-support and researches. The documentations of prenatal care provided data that can be more fluently communicated, compared and evaluated across various healthcare providers and clinic settings. © 2016 International Council of Nurses.

A role for NGOs in international renewable energy project development

Energy Technology Data Exchange (ETDEWEB)

Bartholf, T.R.

1997-12-01

An NGO is an international term for non-government organizations, often it is used in connection with non-profit, community-based and/or voluntary business activities. To be successful in supporting energy projects, these organizations generally exhibit certain characteristics: they are familiar with the end-use requirements; they are typically neutral to the technology; they emphasize training; they do not carry a large bureacratic structure, at home or in the field; they typically can adapt to do numerous functions; they can often attract other support. The author discusses several examples of such organizations who have been highly successful. The author sees a continuing role for such groups in developing renewable energy sources in the rural setting to include: continued development of new activity in rural areas; development of institutional framework for future market activity; an increased role in managing international development activities; more direct involvement with for-profit technical and financial organizations.

[International trends of applied ecology and its future development in China].

Zhou, Qixing; Sun, Shunjiang

2002-07-01

Internationally applied ecology was born around 25-40 years ago in order to adapt and serve the needs of mitigating increasingly environmental pollution and ecological destroy in developed western countries at that time. All the times applied ecological principles thus underpin most efforts at solving increasingly deterioration of natural resources and serious eco-environmental problems as its keystone and researching kernel with the development of the subject. At the advent of the 21st century, human beings enter into the age of applied ecology. There are five international features of applied ecology, including more attention to many-sided applications, special emphasis on the intersection with engineering, strongly keeping on mutual links with basic ecology, omnidirectional adoption of new methods and new technology, and side-by-side trends of microcosmic mechanisms and macroscopical regulation. Although we must connect with international applied ecology and absorb distillates from the subject in developed western countries, development of applied ecology in China in the future, in particular, at the beginnings of the 21st century should not deviate from aiming at the solution of increasingly environmental pollution and ecological destroy that is one of the most important basic situations of the country.

Progress towards developing an international repository for radioactive waste

International Nuclear Information System (INIS)

Kurzeme, M.

2001-01-01

Pangea Resources was established to develop and promote the concept of international repositories. The concept was based on repositories located in geologically stable, flat, arid environments meeting the 'high isolation' criteria developed by Pangea Resources. The high isolation concept of Pangea Resources can be applied in various regions of the world, and these have been made public. The pilot project chosen for exploring feasibility was for an international repository in Australia. This study was in preparation for public release, when the existence of the proposal was prematurely revealed to the media. The general media and public reaction to the concept was understandably negative. However, there were also some opinion pieces reported suggesting that the concept of an international repository should be thought about seriously, before it is accepted or rejected. In addition, thoughtful reactions were received from the business and scientific communities. In particular a group of very eminent scientists, the Scientific Review Group, undertook to review independently the quality of the work done. Nevertheless, the reaction from the state and federal governments, was also negative. The Australian Government stated its policy not to permit importation or disposal of foreign nuclear waste. During the last two years Pangea Resources has been developing the technical aspects of the concept and has produced and published several scientific reports on transport, storage and disposal of radioactive materials. All the scientific studies of Pangea Resources have been reviewed by the Scientific Review Group. The work has also been presented in scientific conferences, to the media (including a dedicated television documentary) and to the public. The technical work is generic or is based on diverse potential siting areas around the world and the disposal and storage technologies studied are being broadened beyond the specific high-isolation concept. Most importantly, it has

Ten years of Developing International Volcanology Graduate Study Programs

Rose, W. I.

2010-12-01

In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by

International breeder reactor development

International Nuclear Information System (INIS)

Traube, K.

1976-01-01

For more than a decade, sodium cooled breeder reactors have now been in the focus of advanced nuclear power development in the major industrialized countries. In the sixties, a total of seven small experimental nuclear power stations were commissioned. Two of these have been shut down in the meantime, the others continue to work satisfactorily, their main purpose being the development of fuel elements. The years 1972-1974 saw the commissioning of the prototype power stations in the 300 MWe power category in France, the United Kingdom and the Soviet Union. Presently, other experimental reactors are under construction in the Federal Republic of Germany, Italy, Japan, the United States, plus another Soviet 600 MWe prototype reactor and the SNR 300 DeBeNeLux prototype at Kalkar. A comparison of the technological features either implemented or planned in the prototype and experimental power plants and of their fuel elements reveals a remarkable similarity in the basic concepts pursued in different countries. The two types of breeder reactors, viz. the loop and the pool types, show a closer resemblance to each other than do pressurized and boilling water reactors. The growing awareness of administrative problems emerging in the approaching phase of the introduction of large breeder power stations in a number of European countries has recently led to a streamlining effort in the structure of industries and to tentative steps towards international cooperation on a broad basis.

International development and the ecuation of power within the European Union

Directory of Open Access Journals (Sweden)

Magda Simona SCUTARU

2015-06-01

Full Text Available Within the European Union, we can talk about a high degree of power and this means that states have different capacities to reach prosperity, but they also have the capacity to help other states reach a similar degree of welfare. Development Assistance plays a very important role in the world, being offered to states which can not surpass economic, social or political difficulties. In order to reach a certain balance at the international level, between levels of development that states possess, a fundamental need occurs: states that are economically, socially and politically left behind must receive development assistance. The present work aims to analyse the degree to which the European Union contributes to international development. Both EU institutions and EU and OECD member states play fundamental roles on the world stage by granting funds to fragile and less developed states.Rethinking the third world might mean a restructuring of the political systems of states and of their economic systems, so that these countries become more developed and less dependent on other states. European institutions and assistance policies also need to change their way of regarding the matter of international development and of approaching the problem of poverty so that the needs of the third world states could be satisfied in an appropriate manner. Europe has the role of transformative power because it helps the third world states develop their economies and political systems so that they could satisfy the needs of their citizens. As a consequence, these economies are transforming. They are not autarchic systems, so when we are talking about transformation, we are talking about development.

Development of international guidelines for RAM shipment security

Energy Technology Data Exchange (ETDEWEB)

Luna, R.E.

2004-07-01

In October of 2003 a weeklong IAEA Technical Meeting developed a set of guidelines for providing security to consignments of radioactive materials in transport. These guidelines will be published shortly in an IAEA TECDOC. The guidelines produced reflect consideration of many influences and concerns that currently revolve around the potential for terrorist use of radioactive material for malevolent ends. The influences discussed here include: public perception of hazard and concern that new requirements will further limit global shipping capability, international efforts to control sealed sources, national efforts to increment protection on selected materials, the basis for exemption of materials, concern for cost impacts of overly broad requirements, questions on how to adjust requirements for a national threat assessment, and issues relating to consistency within the international community on security needs.
