Abstract:

Active containment systems based on the controlled expression of a lethal gene are designed to increase containment of recombinant micro-organisms used for environmental applications. A major drawback in containment is the existence of mutations that generate surviving cells that cease to respond to the toxic effect of the lethal function. In this work the authors have developed for the first time a strategy to reduce the problem of mutations and increase the efficiency of containment based on the combination of two lethal functions acting on different cellular targets of major concern in containment, DNA and RNA, and whose expression is under control of different regulatory signals. To engineer the dual gene containment circuit, two toxin–antitoxin pairs, i.e. the colicin E3–immunity E3 and the EcoRI restriction–modification systems, were combined. The genes encoding the immunity E3 and the EcoRI methyltransferase proteins (antitoxins) were stably inserted into the chromosome of the host cell, whereas the broad-host-range lethal genes encoding the colicin E3 RNase and the EcoRI restriction endonuclease (toxins) were flanking the contained trait in a plasmid. This dual lethal cassette decreased gene transfer frequencies, through killing of the recipient cells, by eight orders of magnitude, which provides experimental evidence that the anticipated containment level due to the combination of single containment systems is generally achieved. Survivors that escaped killing were analysed and the mutational events involved were characterized.

Abstract:

Rectangular dual graph approach to floorplanning is based on the adjacency graph of the modules in a floorplan. If the input adjacency graph contains a cycle of length three which is not a face (complex triangle), a rectangular floorplan does not exist. Thus, complex triangles have to be eliminated before applying any floorplanning algorithm. This paper shows that the weighted complex triangle elimination problem is NP-complete, even when the input graphs are restricted to 1-level containment. For adjacency graph with 0-level containment, the unweighted problem is optimally solvable in O(c1.5 + n) time where c is the number of complex triangles and n is the number of vertices of the input graph.

Abstract:

This thesis is a critical analysis of US foreign policy toward Iran and Iraq known as a policy of dual containment. The objective of dual containment is to isolate these regimes politically, economically and militarily. This thesis evaluates American conduct in the region for the last 50 years, in order to show how previous strategies culminated in the present policy. It discusses both the merits and problems inherent in dual containment, as well as the impact of this policy on its two intended recipients. In closing, the thesis offers possible policy options, including an analysis of their specific advantages and disadvantages. The findings of this research conclude that dual containment is a sustainable policy in the near term and ensures that US vital national interests in the region are not challenged. In the long term, however, it is argued that America needs to initiate a policy of incremental engagement toward both Iran and Iraq. This strategy should begin with economic ties leading eventually to diplomatic relations. Nevertheless, both regimes need to demonstrate the desire and ability to accept the standards of behavior as established by the community of nations.

Abstract:

This thesis examines the American policy of ‘dual containment’: the assumption by the US of a predominant role in the security system of the Persian Gulf in the 1990s, necessitating the simultaneous ‘containment’ of both Iran and Iraq. American policy towards Iran receives special attention thanks to its more unusual aspects, including the vehemence of American attempts to isolate it. While other scholars have sought to explore the empirical aspects of this policy, this thesis seeks to place it within an overarching theoretical framework derived from neoclassical realism (NCR). Additionally, the thesis integrates insights drawn from Foreign Policy Analysis (FPA) to explain the impact of domestic variables on the formation of American policy towards Iran and Iraq during this era. In terms of domestic factors, the thesis identifies three key ‘intervening variables’ and their role in the adoption and evolution of dual containment: perceptions of threat on the part of policymakers, domestic political structures, and the operation of policy coalitions. In terms of the external, the role of the idiosyncratic ‘tripolar’ dynamics of the Persian Gulf region in shaping American policy is examined, as is the longstanding American interest in the Persian Gulf as an area of important national interest and key importance in the global economy, which endured into the 1990s despite the end of the Cold War. The thesis concludes that US policy towards Iran and Iraq was shaped by the intervening variables it identifies and examines. It strongly reflected the perceptions held by American policymakers of American power, and also of Iran and Iraq as ‘rogue’ or ‘outlaw’ states, and the measures perceived as necessary to advance Arab-Israeli peace. Moreover, it also reflected the influence of domestic interest groups and Congressional activism in the realm of foreign policy.

Abstract:

La politique étrangère américaine envers l’Irak de 1990 à 2003 s’est développée suite à la chute du bloc soviétique et au changement du système de gouvernance mondial en 1990. Elle connait une rupture avec celle suivie durant la guerre froide, mais elle continue d’osciller entre unilatéralisme et multilatéralisme, mais toujours en privilégiant les intérêts américains. Ce changement a exigé alors de revoir les relations américano- irakiennes, surtout après le conflit qui a opposé l’Iran et l’Irak et face aux ambitions régionales irakiennes. Mais, la nouvelle approche des États-Unis envers l’Irak n’a été mise en œuvre qu’au lendemain de l’invasion du Koweït, via les sanctions onusiennes et l’opération Tempête du Désert. Motivée par l’exigence inconditionnelle du retrait irakien du Koweït, elle avait aussi un objectif non déclaré visant à affaiblir Saddam Hussein. Cette politique se poursuit avec le président Clinton, via le double endiguement appliqué envers l’Irak et l’Iran. Elle ne tarde pas à évoluer vers l’objectif de renverser le régime Baasiste qui figurait à l’agenda de responsables américains mais sans être appliquée. En 1998, la loi Libération de l’Irak adopte le changement de régime en Irak. Encouragé par les néoconservateurs, ce changement a été motivé par les attentats de 11 septembre 2001 qui ont enclenché une nouvelle politique étrangère américaine pour lutter sans merci contre le terrorisme. Cette politique a provoqué en 2003 le renversement du régime de Saddam Hussein en Irak. Après cette période, les relations entre ces deux pays passent par une nouvelle phase. Par ailleurs, le Moyen-Orient et l’Irak connaissent une montée de l’Islam politique et radical et de l’influence iranienne. Vingt ans après, les évènements de cette période et la politique étrangère américaine menée en Irak ont encore aujourd’hui de lourdes conséquences sur ce pays et sur l’ensemble du Moyen-Orient
American foreign policy towards Iraq from 1990 to 2003 has been developed subsequently to the fall of the Soviet bloc and the change of world governance system in 1990.This policy towards Iraq from 1990 to 2003 was different than that practiced during the Cold War, even though it continued to oscillate between unilateralism and multilateralism, prioritizing American interests. This change then necessitated a review of the US-Iraqi relations, especially after the conflict between Iran and Iraq and considering the Iraqi regional ambitions. But the new US approach towards Iraq was implemented only after the invasion of Kuwait, via the UN sanctions and the ‘Desert Storm’ operation. Motivated by the unconditional requirement for Iraqi withdrawal from Kuwait, it also had an undeclared objective which aimed to weaken Saddam Hussein. The same policy continued with President Clinton, through the double containment applied to both Iraq and Iran. However, this policy does not take long to change to the objective of overthrowing the Baath regime which appeared in American officials but without being applied. In 1998, the Iraq Liberation Act adopted this change. Encouraged by the neoconservatives, this change was motivated by the attacks of September 11, 2001, which lead to a new American foreign policy without mercy to fight against terrorism. This policy ended up bringing about the overthrow in 2003 of the political regime of Saddam Hussein in Iraq. After this period, the relations between both countries move to a new step. In addition, the Middle East and Iraq in particular knew a rise in political and radical Islam and Iranian influence as well. Twenty years later, these events and the American foreign policy carried out in Iraq from 1990 to 2003 still have serious consequences on Iraq and on the whole Middle East Region as well

Abstract:

Double containment piping systems are used extensively for handling the conveyance of critical waste systems in industries such as pharmaceuticals and biotechnology manufacturing and research. Often, these services involve the conveyance of critical fluids at elevated temperatures. An example would be in the discharge and transport of spent fermentation by-products in the biotech industry, where the vessel contents are sanitized by the addition of water at up to 210°F and then discharged through double containment piping. Materials of construction used in such systems include thermoplastic, RTRP (fiberglass), stainless steel systems, and combinations thereof. This paper compares systems that are fully restrained by means of patented internal anchors designed to reduce stresses in components and evenly distribute the stresses to the secondary containment components. The systems are compared to the conventional methods of using thermoplastic systems restrained by unitary anchors. In addition to finite element analysis, physical tests are also performed to demonstrate the effectiveness of the conical shaped anchors.

Abstract:

The first Japanese spent fuel interim storage facility away from a reactor site is about to be commissioned in Mutsu City, Aomori Prefecture. In designing, licensing and construction of the Dual Purpose Casks (DPCs, for transport and storage) for this facility, codes and standards established by the Atomic Energy Society of Japan (AESJ) and by the Japan Society of Mechanical Engineers (JSME) have been applied. The AESJ established the first standard for DPCs as “Standard for Safety Design and Inspection of Metal Casks for Spent Fuel Interim Storage Facilities” in 2002 (later revised in 2010). The standard provides the design requirements to maintain the basic safety functions of DPCs, namely containment, heat removal, shielding, criticality prevention and the structural integrity of the cask itself and of the spent fuel cladding during transport and storage. Inspection methods and criteria to ensure maintenance of the basic safety functions and structural integrity over every stage of operations involving DPCs including pre-shipment after storage are prescribed as well. The structural integrity criteria for major DPC components refer to the rules provided by the JSME. JSME completed the structural design and construction code (the Code) for DPCs as “Rules on Transport/Storage Packagings for Spent Nuclear Fuel” in 2001 (later revised in 2007). Currently, the scope of the rules cover the Containment Vessel, Basket, Trunnions and Intermediate Shell as major components of DPCs. Rules for these components are based on those for components of nuclear power plants (NPP) with similar safety functions, but special considerations based on their shapes, loading types and required functions are added. The Code has differences from that for NPP components with considerations to DPC characteristics; - The primary stress and the secondary stress generated in Containment Vessels shall be evaluated under Service Conditions A to D (from ASME Sec III, Div.1). - Stress generated in the seal region lid bolts of Containment Vessels shall not exceed yield strength under Service Conditions A to D in order to maintain the containment function. - Fatigue analysis on Baskets is not required, and Trunnions can be designed only for Service Conditions A and B with special stress limits consistent with conventional assessment methods for transport packages. - Stress limits for earthquakes during storage are specified. - Ductile cast iron with special fracture toughness requirements can be used as a material for Containment Vessels. DPC specific considerations in standards and rules will be focused on in this paper. Additionally, comparison with the ASME Code will be discussed.

Abstract:

Abstract A nested confinement (inner) and containment (outer) vessel system is under development to conduct small shock-physics experiments in a high-speed proton imaging facility at Los Alamos National Laboratory. The dual vessel system is necessary to serve as a qualified confinement system and containment buffer boundary between a high explosives experiment and the environment. The paper describes the preliminary engineering design and analyses that have been performed on the outer containment pressure vessel, following ASME BPVC Sect. VIII Div. 1, for both pressure and vacuum conditions. Other engineering attributes which will be presented include an internal support structure for a nested inner vessel, an external integrated support and alignment structure for the complete vessel system, and the vacuum and gas handling equipment.

Abstract:

The 9975 shipping package is used to store plutonium bearing material with a heat release of up to 19 Watts at the Department of Energy (DOE) Savannah River Site (SRS). Individual 9975 packages have been used to store these materials for nearly 15 years. The 9975 package contains non-metallic components such as the elastomeric dual O-ring seals, used to ensure containment at the vessel closures, and a fiberboard over pack which provides impact and fire resistance to the containment vessels. These non-metallic components degrade during long term storage, particularly when higher heat generating contents are packaged. Degraded fiberboard properties result in higher peak internal 9975 package material temperatures during a fire accident event. The thermal performance of the 9975 shipping package was evaluated for a sequential accident consisting of a fire and drop which locally ruptures the outer drum. The package is exposed to an off-normal 58.3°C (137°F) ambient temperature prior to being fully engulfed in a fire for 1.5 hours at 815.6°C (1500°F). Subsequently the fiberboard smolders for 1.0 hour at 760°C (1400°F) at the location of drum rupture, followed by cool down to the ambient temperature. The thermal evaluation considered both the beginning-of-life (as-designed) condition and after 20 years of service as a plutonium material storage container. The results of the evaluation demonstrate that the 9975 shipping package maintains containment during initial and after 20 years of service. The maximum Primary Containment Vessel dual O-ring temperatures during the facility fire-drop-smoldering accident are 163.9°C (327°F) and 186.1°C (367°F) for beginning of life and after 20 years of service, respectively, which are within the allowable accident temperature limit of 204.4°C (400°F). Thus, the 9975 shipping package meets its intended function to provide containment.

Abstract:

An experimental facility is being set up at Bhabha Atomic Research Centre for studying the thermal-hydraulic behavior of Indian Pressurized Heavy water Reactors under normal and accidental conditions. The set up simulates the containment of the reactor and the Primary Heat Transport System (PHTS). In experimental set up, the PHTS simulation vessel is placed outside the containment building and the piping system connects it to the containment building. The steam-water mixture produced in the PHTS vessel will be discharged into the containment to simulate various postulated accidental conditions. The piping system consists of quick opening dual assembly rupture disk and valves. Various layouts of the piping system had been studied with due considerations to the site constraints. Rupture disk location has been finalized considering its operational requirements. Supporting arrangement has been arrived at with due consideration to the various service load requirements. Subsequently, additional supports have been incorporated to increase system frequency. This paper deals with the various considerations made and strategy adopted for finalisation of layout and to meet the codal requirements.

Abstract:

Abstract La Luna Shale in Colombia is the main source rock in the Middle Magdalena Valley (MMV) and the Catatumbo Basins. La Luna shale is a high-quality source rock and its potential has been investigated by several authors. This paper presents geological, geochemical, and petrophysical description of La Luna shale with the dual objective of (1) utilizing CO2 for improving oil recovery through Huff-n-Puff (HnP) gas injection, and (2) storing CO2 safely and without leaks. The overall approach includes verifying that geologic fluid containment exists in the shale reservoir. The present work shows that this is indeed the case in La Luna shale. Geologic containment is valuable as it permits maximizing oil recovery from La Luna shale and safe storage of CO2 with negligible possibilities of fluid leakage, thus providing a valuable contribution to solve problems related to climate change. Consequently, the procedure described in this paper conforms well to CCUS: Carbon capture, utilization and storage of CO2. The Eagle Ford shale in Texas is a good analog of La Luna shale. In both reservoirs, sedimentation and development of the source rock start at about the same time in the late Cretaceous, about 93 million years ago. It is not surprising then that in both Eagle Ford and La Luna shales, oil, condensate and natural gas are in the same location where they were generated, gas is at the bottom, condensate in the middle and crude oil at the top of the structure. Thus, the hydrocarbon fluids have been upside down or inverted position through millions of years. This constitutes geologic containment. The paper describes the following activities once geologic containment is established: (1) drill a pilot horizontal well (HW), (2) stimulate the HW with multi-stage hydraulic fractures and investigate the environmental impact (if the pilot is successful, drill another pilot(s)), (3) produce oil by primary means for a maximum of 2-3 years, (4) implement HnP CO2 injection, (5) store the CO2 in the shale reservoir once the HnP reaches economic limit. Regular pressure monitoring throughout the life of the HnP project guarantees the lack of leaks, a major concern when CO2 is stored in other types of depleted reservoirs or aquifers. The novelty of the paper is demonstrating geologic containment in La Luna shale in both the MMV and Catatumbo Basins of Colombia. This provides the basis for implementing CCUS. The geological, geochemical and petrophysical description allow to construct a simulation model to investigate primary recovery as well as EOR by HnP CO2 injection. CO2 can be stored safely, without leaks, in the shale reservoir once the HnP project reaches economic limit.

Abstract:

Abstract The objective of this work was to quantify the in-situ stress contrast between the reservoir and the surrounding dense carbonate layers above and below for accurate hydraulic fracturing propagation modelling and precise fracture containment prediction. The goal was to design an optimum reservoir stimulation treatment in a Lower Cretaceous tight oil reservoir without fracturing the lower dense zone and communicating the high-permeability reservoir below. This case study came from Abu Dhabi onshore where a vertical pilot hole was drilled to perform in-situ stress testing to design a horizontal multi-stage hydraulic fractured well in a 35-ft thick reservoir. The in-situ stress tests were obtained using a wireline straddle packer microfrac tool able to measure formation breakdown and fracture closure pressures in multiple zones across the dense and reservoir layers. Standard dual-packer micro-injection tests were conducted to measure stresses in reservoir layers while single-packer sleeve-frac tests were done to breakdown high-stress dense layers. The pressure versus time was monitored in real-time to make prompt geoscience decisions during the acquisition of the data. The formation breakdown and fracture closure pressures were utilized to calibrated minimum and maximum lateral tectonic strains for accurate in-situ stress profile. Then, the calibrated stress profile was used to simulate fracture propagation and containment for the subsequent reservoir stimulation design. A total 17 microfrac stress tests were completed in 13 testing points across the vertical pilot, 12 with dual-packer injection and 5 with single-packer sleeve fracturing inflation. The fracture closure results showed stronger stress contrast towards the lower dense zone (900 psi) in comparison with the upper dense zone (600 psi). These measurements enabled the oilfield operating company to place the lateral well in a lower section of the tight reservoir without the risk of fracturing out-of-zone. The novelty of this in-situ stress testing consisted of single packer inflations (sleeve frac) in an 8½-in hole in order to achieve higher differential pressures (7,000 psi) to breakdown the dense zones. The single packer breakdown permitted fracture propagation and reliable closure measurements with dual-packer injection at a lower differential reopening pressure (4,500 psi). Microfracturing the tight formation prior to fluid sampling produced clean oil samples with 80% reduction of pump out time in comparison to conventional straddle packer sampling operations. This was a breakthrough operational outcome in sampling this reservoir.

Abstract:

A Jet Fuel Starter (JFS) is used to start the F100 main propulsion engines for the F-15 fighter aircraft. The JFS is a dual rotor machine which consists of a gas generator spool and a power turbine spool. The gas generator turbine wheel was designed to be contained within the turbine case in the event of a JFS overspeed. This is done by the inclusion of a containment ring in the turbine case. The initial power turbine wheel design was not able to be contained by its turbine case. A design decision was made to make this wheel frangible, that is, in an overspeed condition the wheel would break into small pieces which could be contained by the existing turbine case. An alternative design solution is proposed in this paper and an analytical proof-of-concept is presented.

Abstract:

Abstract Carbon steel pipelines are used to transport hydrocarbons globally because carbon steel is relatively easier to fabricate, safe for use, raw materials are available and less expensive. Amidst these benefits, carbon steel is susceptible to severe corrosion and other anomalies. Pipeline corrosion is a significant concern in the oil and gas industry. It has caused several minor and catastrophic losses of containment with resultant fatalities, environmental pollutions, asset damage, and production downtimes. The increasing failures of in-service pipelines have led the Department of Petroleum Resources (DPR) to intensify regulatory scrutiny of pipeline integrity assessment and management in Nigeria to ensure strict compliance to the regulatory requirements by the Oil Producing Companies. According to DPR Act (Section 2.5.2.1), all pipelines greater than 6" size diameter must be inspected every five (5) years with intelligent pigs (inline inspection tools) that would provide the accurate condition of the pipeline. However, many pipelines in Nigeria are unpiggable or difficult to inspect with intelligent pigs due to the unavailability of pigging facilities (especially in brownfields), pipelines with short bend radiuses, dual diameters, flow parameters, etcetera. This paper explores case studies involving the use of advanced inline inspection technology to conduct inline inspection of difficult-to-inspect dual-diameter pipelines.
