    Full Text Available Presently in work zones, standard barricade warning lights are used to provide channelizing and warning functions. These yellow flashing lights are presently used for different work zone activities. Concepts for a non-standard barricade lighting system were developed and evaluated: flashing red lights when traffic is stopped or very slow within a work zone, flashing green lights when a work zone is inactive and traffic should proceed normally, expanding yellow lights when drivers should slow down and exercise enhanced caution, and sweeping yellow lights when lane closures require drivers to move to the right or left. Prototype units were designed and fabricated. A survey of driver understanding of these functions indicated that drivers would probably understand all of the functions but that the flashing red and green functions could result in conflicts with other roadway traffic control devices. A field evaluation of the expanding and sweeping functions in mock-up work zones demonstrated that driver comprehension of the lights could be translated to a driving situation. Drivers changed lanes sooner (providing a 40% longer lane change margin in response to the sweeping function than to conventional flashing barricade lights, and subjective ratings about the intended meaning of the tested functions were also positive.

    An improved less-than-lethal projectile for use in hostage, barricade and tactical assault situations has been developed. The projectile is launched from a standoff position and disperse the incapacitating agent oleoresin capsicum in the form of atomized droplets. A literature search followed by an experimental study were conducted of the mechanism of barrier defeat for various shaped projectiles against the targets of interest in this work: window glass, plasterboard and plywood. Some of the trade- offs between velocity, standoff, projectile shape and size, penetration, and residual energy were quantified. Analysis of the ballistic trajectory and recoil, together with calculations of he amount of pepper spray needed to incapacitate the occupants of a typical barricaded structure, indicated the suitability of using a fin stabilized projectile fired from a conventional 37 mm riot control gas gun. Two projectile designs were considered, manufactured and tested. The results of static tests to simulate target impact, together with live firing trials against a variety of targets, showed that rear ejection of the atomized spray was more reproducible and effective than nose ejection. The performance characteristics of the finalized design were investigated in trials using the standard barrier for testing barrier penetrating tear gas agents as defined by the National Institute of Justice.

  4. Moisture and textural variations in unsaturated soils/sediments near the Hanford Wye barricade

    International Nuclear Information System (INIS)

    During November and December 1983, soil samples were collected by Pacific Northwest Laboratory for hydrologic characterization of the partially saturated (vadose) zone sediments from five wells drilled near the Hanford Wye barricade, about 15 km northwest of Richland, Washington. The samples were taken from each of five boreholes in 1.5-m segments down to the water table or to a depth where further drilling became impossible, whichever was deeper. The samples were collected and handled in such a manner as to minimize water loss through evaporation. The field moisture content was determined for each sample, and for three of the five boreholes the water potential at the field moisture content was also measured. Other characterization included textural analysis, water retention characteristics, hydraulic conductivity, and soil chemistry. From the laboratory data, travel time (i.e., the time necessary for water to move a distance of 43 m, from the soil surface to the ground water) estimates were calculated: they range from 600 years for annual water influx rates that ranged from 0.5 to 5.0 cm/yr. The soil properties determined in this study will aid in modeling the transport of water and chemicals (e.g., radionuclides) to the ground water at the Hanford site

  9. The bitter barricading of prostaglandin biosynthesis pathway: understanding the molecular mechanism of selective cyclooxygenase-2 inhibition by amarogentin, a secoiridoid glycoside from Swertia chirayita.

    Directory of Open Access Journals (Sweden)

    Shantanu Shukla

    Full Text Available Swertia chirayita, a medicinal herb inhabiting the challenging terrains and high altitudes of the Himalayas, is a rich source of essential phytochemical isolates. Amarogentin, a bitter secoiridoid glycoside from S. chirayita, shows varied activity in several patho-physiological conditions, predominantly in leishmaniasis and carcinogenesis. Experimental analysis has revealed that amarogentin downregulates the cyclooxygenase-2 (COX-2 activity and helps to curtail skin carcinogenesis in mouse models; however, there exists no account on selective inhibition of the inducible cyclooxygenase (COX isoform by amarogentin. Hence the computer-aided drug discovery methods were used to unravel the COX-2 inhibitory mechanism of amarogentin and to check its selectivity for the inducible isoform over the constitutive one. The generated theoretical models of both isoforms were subjected to molecular docking analysis with amarogentin and twenty-one other Food and Drug Authority (FDA approved lead molecules. The post-docking binding energy profile of amarogentin was comparable to the binding energy profiles of the FDA approved selective COX-2 inhibitors. Subsequent molecular dynamics simulation analysis delineated the difference in the stability of both complexes, with amarogentin-COX-2 complex being more stable after 40ns simulation. The total binding free energy calculated by MMGBSA for the amarogentin-COX-2 complex was -52.35 KCal/mol against a binding free energy of -8.57 KCal/mol for amarogentin-COX-1 complex, suggesting a possible selective inhibition of the COX-2 protein by the natural inhibitor. Amarogentin achieves this potential selectivity by small, yet significant, structural differences inherent to the binding cavities of the two isoforms. Hypothetically, it might block the entry of the natural substrates in the hydrophobic binding channel of the COX-2, inhibiting the cyclooxygenation step. To sum up briefly, this work highlights the mechanism of the possible selective COX-2 inhibition by amarogentin and endorses the possibility of obtaining efficient, futuristic and targeted therapeutic agents for relieving inflammation and malignancy from this phytochemical source.

  14. A numerical evaluation of continuous backfilling in cemented paste backfilled stope through an application of wick drains

    Institute of Scientific and Technical Information of China (English)

    Li Li; Yang Pengyu

    2015-01-01

    Cemented paste backfill (CPB) is gaining popularity in many underground mines worldwide. Sufficient water is added into CPB to make a flowable material for pipe transportation. Barricades are built near the drawpoints to prevent in-rush of the fill slurry. To avoid barricade failures resulting from excessive backfill pressures, backfilling is typically performed with a plug pour followed by a final pour. The inter-val between the two pours should be shortened or removed to increase mining productivity and avoid pipe clogging. Recently, Li proposed to apply wick drains in backfilled stopes to promote drainage and consolidation. The preliminary simulations by considering an instantaneous filling indicated that the drainage of CPB can be significantly accelerated by using wick drains. Barricade was not considered. Here, some new numerical modellings are presented with more representative filling sequences, stope geometry, and different draining configurations. The results illustrate that the stope can be backfilled continuously by using wick drains.

  2. Equipment Used Prior to Turnover to Operations: Lessons Learned on Communication and Material Segregation, Savannah River Nuclear Solutions, United States of America

    International Nuclear Information System (INIS)

    In late 2013, the procurement of 200 new L-Area bundles was initiated as part of a project to install new storage racks in the L-Area basin. The L-Area bundles are safety significant (SS) aluminum tubes used to contain spent fuel assemblies within the storage racks. Following initiation of rack and bundle procurement, the rack installation project was cancelled with the agreement to fund receipt of the racks and bundles but stop short of rack installation. During fabrication of the bundles by an offsite vendor, a supplier deviation disposition request (SDDR) was initiated to allow an additional alloy of aluminum and a different fabrication method to be used for fabrication of the bundle lids. Incorporation of the associated design changes into site drawings was to be performed at a later date due to competing priorities. Fabrication of the L-Area bundles was completed and the bundles were delivered to the L-Area in January 2013. Because the SDDR driven design change had not been incorporated into the site drawing, a decision was made to segregate the bundles to prevent inadvertent use. Operators receiving the bundles were told to barricade the bundles, but the reason for the barricade was not adequately communicated. As a result, the bundles were stored near previously accepted bundles with a barricade that specified only property, plant and equipment (PPE) required to enter. The reason for the segregation was later verbally communicated during weekly safety focus meetings. In May 2013, during preparations for unloading of an offsite spent fuel shipment, operators were sent to obtain two L-Area bundles. Bundles were selected from the accepted batch. However, owing to issues regarding the fit, lids were selected from the batch of new bundles within the barricade. The bundles were then loaded with spent fuel and stored in the L-Basin racks. Days later, during a facility walk-down, an L-Area shift operations manager (SOM) noticed that two of the new bundle lids were

    2000-01-01

    This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

    Science.gov (United States)

    Thomas, Sunil; Prendergast, George C

    2016-01-01

    Vaccine approaches for cancer differ from traditional vaccine approaches for infectious disease in tending to focus on clearing active disease rather than preventing disease. In this review, we provide a brief overview of different types of vaccines and adjuvants that have been investigated for the purpose of controlling cancer burdens in patients, some of which are approved for clinical use or in late-stage clinical trials, such as the personalized dendritic cell vaccine sipuleucel-T (Provenge) and the recombinant viral prostate cancer vaccine PSA-TRICOM (Prostvac-VF). Vaccines against human viruses implicated in the development and progression of certain cancers, such as human papillomavirus in cervical cancer, are not considered here. Cancers express "altered self" antigens that tend to induce weaker responses than the "foreign" antigens expressed by infectious agents. Thus, immune stimulants and adjuvant approaches have been explored widely. Vaccine types considered include autologous patient-derived immune cell vaccines, tumor antigen-expressing recombinant virus vaccines, peptide vaccines, DNA vaccines, and heterologous whole-cell vaccines derived from established human tumor cell lines. Opportunities to develop effective cancer vaccines may benefit from seminal recent advances in understanding how immunosuppressive barricades are erected by tumors to mediate immune escape. In particular, targeted ablation of these barricades with novel agents, such as the immune checkpoint drug ipilimumab (anti-CTLA-4) approved recently for clinical use, may offer significant leverage to vaccinologists seeking to control and prevent malignancy.

    Mine backfilling can play a significant role in the overall operation of a mine operation. In the Australian mining industry, where safety is a prime consideration, hydraulic systems are the most common backfills deployed. Many accidents reported at hydraulic fill mines worldwide have mainly been attributed to a lack of understanding of their behaviour and barricade bricks. There are two basic types of backfilling strategies. The first, uncemented backfilling, does not make use of binding agents such as cement, and their characteristics can be studied using soil mechanics theories. A typical example of uncemented backfilling is the use of hydraulic fills that are placed in the form of slurry into the underground voids. The second category, cemented backfilling, makes use of a small percentage of binder such as Portland cement or a blend of Portland cement with another pozzolan such as fly ash, gypsum or blast furnace slag. This paper describes the findings from an extensive laboratory test programme carried out in Australia on more than 20 different hydraulic fills and several barricade bricks. A limited description of paste backfills is also provided, and the usefulness of numerical modelling as an investigative tool is highlighted. 21 refs., 10 figs., 1 tab.

  14. Protected train - protecting available/running equipment

    International Nuclear Information System (INIS)

    'Full text': Nuclear Plants are designed using a 'Defense in Depth' approach to keeping the fuel cool. As such, primary and shutdown fuel cooling systems and their supporting systems are designed with redundant and/or backup pumps, power supplies, and controls. During maintenance the backup 'train' may be removed from service leaving only one set of fuel cooling or support apparatus. For a number of years maintenance occurred at Point Lepreau NGS without a set of boundaries and standards to protect available/running equipment while the alternate train was removed from service for routine or breakdown maintenance or upgrades. This less than desirable practice was corrected by developing 'Protected Train' procedures. By identifying, barricading and regularly inspecting sensitive 'Protected' equipment we reduce the risk to fuel cooling systems and thus improve Nuclear Safety. (author)

    Full Text Available Through-the-wall imaging (TWI is a difficult but important task for both law enforcement and military missions. Acquiring information on both the internal features of a structure and the location of people inside plays an important role in many fields such as antiterrorism, hostage search and rescue, and barricade situations. Up to now, a number of promising experimental systems have been developed to validate and evaluate diverse imaging methods, most of which are based on a linear antenna array to obtain an image of the objects. However, these methods typically use the backward projection (BP algorithm based on ellipse curves, which usually generates additional ghost images. In this paper, the algorithm using the location inverse solution (LIS to reduce the ghost images is proposed and simulated. The results of simulation show that this approach is feasible.

    2009-04-01

    Flood risk managers educate the public on the dangers of driving through flooded roadways, yet losses to life and property continue to occur. This study integrates cultural psychology and risk perception theory to explore how culture, psychological processes, and behavior influence one another. Flood risk managers in Tucson, Arizona collaborated in the development of a questionnaire mailed to local residents. Questions regarding levels of trust, self-efficacy, social autonomy, social incorporation, time perspective, and situational factors were analyzed with respect to whether respondents stated that they have or have not driven through a flooded roadway. Respondents' decisions are influenced by the presence of signs and barricades, passengers, risk of personal injury or damage to the vehicle, and the availability of flood-related information. The most influential factor is the prior successful crossing of other vehicles. The results illuminate complex interrelations among the cultural factors and provide considerations for future risk perception research.

    Full Text Available L'oeuvre de Sartre pourrait être lue comme Vincamation de l'esprit "pathétique" et "héroïque" de l'époque de la guerre et de la Résistance. Sous le coup de feu des barricades de 44, une philosophie de la révolution commence à éclore-elle fut forgée à chaud durant cette époque de "haute température historique". C'est de la généralisation théorique de cette expérience politique cruciale, c'est-à-dire de la cristallisation du "mythe" de la Résistance, que vient, à mon avis, l'idée satrienne de révolution.

  1. Synthesis and Absorption Characteristics of Two Infrared Cyanine Dyes

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Two infrared dyes, 1,3,3,1', 3', 3'-hexamethylindotricarbocyanine iodide (A) and 1,3,3,1',3',3'-hexamethyl-11-chloro-10,12-propylenetricarbocyanine iodide (B), were synthesized and characterized by melting point, elemental analysis, IR, and 1H-NMR. Their electron absorption spectra, laser absorption characteristics and solubility were investigated. The results showed that A and B have maximum absorption peaks at around 748 nm and 774 nm, respectivey, which match well with the wavelength output of the near infrared laser diode. The dyes were found to have photoinduced fading during irradiation with the infrared laser, especially in the presence of oxygen. However, this procession can be greatly slowed by using a layer of poly(vinyl alcohol) to barricade the dyes from oxygen. The experiments also showed that the dyes were thermally stable but decayed under strong sunlight. Furthermore, they are easily dissolved in some common solvents.

    2016-03-01

    Iron oxide nanoparticles (IONPs) have been a propitious topic for cancer treatment in recent years because of its multifunctional theranostic applications under magnetic field. Two such widely used applications in cancer biology are gradient magnetic field guided targeting and alternative magnetic field (AMF) induced local hyperthermia. Gradient magnetic field guided targeting is a mode of active targeting of therapeutics conjugated with iron oxide nanoparticles. These particles also dissipate heat in presence of AMF which causes thermal injury to the cells of interest, for example tumour cells and subsequent death. Clinical trials divulge the feasibility of such magnetic nano-carrier as a promising candidate in cancer biology. However, these techniques need further investigations to curtail certain limitations manifested. Recent progresses in response have shrunken the barricade to certain extent. In this context, principles, challenges associated with these applications and recent efforts made in response will be discussed.

She claimed i.a.: ”Since we are deliberating, placed in a ho-mophobic culture, where questioning someone’s heterosexual orientation is not an observation but a de­lation, I would compare Zośka and Rudy to Achilles and Patroclus, a pair of legendary warriors. […] I think that this is one of the most beautiful texts about love knowing no limits, whereas all we know about the main characters’ relations testifies to the unheard power and depth of this feeling”. Those words caused an avalanche of reactions, starting from polemics with Janicka or libels on her to violence threats against the scholar. In this conversation, Bożena Keff, Magda Szcześniak, Tomasz Tomasik, Błażej Warkocki and Anna Zawadzka are discussing Janicka’s proposition (developed in her book Festung Warschau, published prior to the quoted text to interpret Stones on the barricades as a text also on a romantic relationship between two men. They analyse social and political causes of the “scandal”, induced by the Polish mainstream media together with a part of the Polish academic milieu. This conversation took place in May 2013.

    Entry to sporulation in bacilli is governed by a histidine kinase phosphorelay, a variation of the predominant signal transduction mechanism in prokaryotes. Sda directly inhibits sporulation histidine kinases in response to DNA damage and replication defects. We determined a 2.0-Angstroms-resolution X-ray crystal structure of the intact cytoplasmic catalytic core [comprising the dimerization and histidine phosphotransfer domain (DHp domain), connected to the ATP binding catalytic domain] of the Geobacillus stearothermophilus sporulation kinase KinB complexed with Sda. Structural and biochemical analyses reveal that Sda binds to the base of the DHp domain and prevents molecular transactions with the DHp domain to which it is bound by acting as a simple molecular barricade. Sda acts to sterically block communication between the catalytic domain and the DHp domain, which is required for autophosphorylation, as well as to sterically block communication between the response regulator Spo0F and the DHp domain, which is required for phosphotransfer and phosphatase activities.

    Full Text Available “The Eighth Day of the Week” The Eighth Day of the Week is a short story by Marek Hłasko revolving around the topic of losing virginity. Literary scholars consider Hłasko as a representative of machismo; a masculine and male-centred narrator. This text analyses and deconstructs the short story defending it as a comprehensive record of misogynist culture written from the perspective of the main female protagonist and not the expression of misogyny of the author himself. The tools of discourse analysis and feminist philosophy applied to Hłasko’s text produce surprising results. Agnieszka – the main female protagonist of the short story – turns out to be a figure of non-conformity universalised by Hłasko, while the virginity and its loss become a part of female fate used by Hłasko as a motif to show the power of society over an individual. Meanwhile Agnieszka struggles for autonomy from domineering cultural patterns and gains it with the help of not so much barricades and spectacular gestures typical for male protagonists as wit, intelligence and trickery.

    We collected soil samples for the physical characterization of a potential fine-soil quarry site at the McGee Ranch, which is located approximately 1 km northwest of the Hanford Site's Yakima Barricade. Forty test borings were made using a hollow-stem auger. Field moisture content and grain-size distribution were determined. The samples were classified into one of 19 sediment classes based on their grain-size distributions. Maps and cross sections were constructed from both the field and laboratory data to delineate the distributions of the various sediment classes. Statistical evaluations were made to determine the variations within the fine-soil fraction of the various sediment classes. Volume estimates were then made of the amounts of soil meeting the preliminary grain-size criteria. The physical characterization of the fine soils sampled near the McGee Ranch site indicated that approximately 3.4 million cubic meters of soil met or exceeded the minimum grain-size criteria for the fine soils needed for the protective barriers program. 11 refs., 14 figs., 6 tabs.

    Full Text Available The Gezi Park barricades in Istanbul, the OWS occupation of Zucotti Park in New York City, the tents of the Indignados movement in Spain, the London Blackberry riots and the seizure of Tahrir Square in Cairo to demand the overthrow of a dictator. As new forms of social coexistence and relationships are being configured, and new spaces for encounter and conflict are produced, architecture feels that essential questions regarding its activity are being addressed in each and every one of these situations. And yet we seem unable to relate to them and grasp their significance as we repeatedly turn to old metaphors and tools. If modern architecture pursues the modern liberal state techniques of management and administration of life, then recent forms of political action, which claim a new relation to the sensible, demand – and might help develop – a new understanding of architecture. We are moving from technical and disciplinary knowledge towards a critical practice that integrates with the action of the multitude. Starting from a definition of commons as the production of the multitude, we seek not only to understand the spatial dimension of this production, but also to acknowledge space as common.

    Full Text Available In many inner city communities in Jamaica, there is the perception that the dons (ad hoc communityleaders are able to provide security, financial assistance and a social safety network, which w as once the roleof the state. The failure of successive governments to provide those important services, in particular securitymeans that there is a high degree of mistrust of the state in rightfully carrying out its roles. The dons have filledthe void created by the state, and people have come to rely on them precisely because of the repeated failuresof successive governments. The mistrust has become so pervasive, that such a low level of trust for governmentleads to a rise in unorthodox political participation. This study examines the role that mistrust in governmentplays in unconventional political participation, and it revealed that Jamaicans who mistrust government are 2.4times more likely to become involved in unorthodox activities compared to those who do trust government.Those activities now include protests, demonstrations, barricading a community, firing at the security forces,blogging, and using the social commentaries on talk radio. While firing at the security forces extends beyondunconventional political participation - and this aspect is not covered in the present manuscript - it is clearlyan unorthodox method employed by some groups within a society.

    2015-01-01

    The vortex formed around the rolling ball and the high pressure region formed around the ball−raceway contact zone are the principle factors that barricades the lubricant entering the bearing cavity, and further causes improper lubrication. The investigation of the air phase flow inside the bearing cavity is essential for the optimization of the oil−air two-phase lubrication method. With the revolutionary reference frame describing the bearing motion, a highly precise air phase flow model inside the angular contact ball bearing cavity was build up. Comprehensive factors such as bearing revolution, ball rotation, and cage structure were considered to investigate the influences on the air phase flow and heat transfer efficiency. The aerodynamic noise was also analyzed. The result shows that the ball spinning leads to the pressure rise and uneven pressure distribution. The air phase velocity, pressure and cage heat transfer efficiency increase as the revolving speed increases. The operating noise is largely due to the impact of the high speed external flow on the bearing. When the center of the oil−air outlet fixes near the inner ring, the aerodynamic noise is reduced. The position near the inner ring on the bigger axial side is the ideal position to fix the lubricating device for the angular contact ball bearing.

    Human skin apart from functioning as a physical barricade to stop the entry of pathogens, also hosts innumerable commensal organisms. The skin cells and the immune system constantly interact with microbes, to maintain cutaneous homeostasis, despite the challenges offered by various environmental factors. A major environmental factor affecting the skin is ultraviolet radiation (UV-R) from sunlight. UV-R is well known to modulate the immune system, which can be both beneficial and deleterious. By targeting the cells and molecules within skin, UV-R can trigger the production and release of antimicrobial peptides, affect the innate immune system and ultimately suppress the adaptive cellular immune response. This can contribute to skin carcinogenesis and the promotion of infectious agents such as herpes simplex virus and possibly others. On the other hand, a UV-established immunosuppressive environment may protect against the induction of immunologically mediated skin diseases including some of photodermatoses such as polymorphic light eruption. In this article, we share our perspective about the possibility that UV-induced immune suppression may alter the landscape of the skin's microbiome and its components. Alternatively, or in concert with this, direct UV-induced DNA and membrane damage to the microbiome may result in pathogen associated molecular patterns (PAMPs) that interfere with UV-induced immune suppression.

    Full Text Available The present article argues that spectacularly proliferating forms of religious populism as a contemporary easily recognisable phenomenon worldwide, Europe included, have administered a deathblow not so much to the classic secularisation paradigm, which has been rather comatose since the early 1990s, as - especially and crucially so - to the updated, narrowed-down, “macro” version of secularisation behind which “neosecularists” within the sociology of religion comfortably barricaded themselves about two decades ago. In the development of this argument, I shall: firstly operationalise “religious populism” as a conceptual and phenomenological subset of populism; secondly I shall provide an overview of the two secularisation theoretical versions; finally I shall address religious populism worldwide in terms of secularisation and specifically isolate the sub-phenomenon of Islamophobic populism which has been increasingly manifesting itself at the societal level in contemporary Western Europe, i.e. the very (supposedly “heartland” of secularity, and which I consider to be the last, and this time decisive, confutation to secularisation theories.

    Full Text Available Poor-quality images mostly result in spurious or missing features, which further degrade the overall performance of fingerprint recognition systems. This paper proposes a reconfigurable scheme of quality checks at two different levels: i at raw image level and ii at feature level. At first level, ellipse properties are calculated through analysis of statistical attributes of the captured raw image. At second level, the singularity points (core and delta are identified and extracted (if any. These information, as quality measures, are used in a cascaded manner to block/pass the image. This model is tested on both publicly available (Cross Match Verifier 300 sensor as well as proprietary (Lumidigm Venus V100 OEM Module sensor fingerprint databases scanned at 500 dpi. The experimental results show that this cascaded arrangement of quality barricades could correctly block poor quality images and hence elevated the overall system accuracy: with quality checks, both FNMR and FMR significantly dropped to 9.52% and 0.26% respectively for Cross Match Dataset and 2.17% and 2.16% respectively for Lumidigm Dataset.

    The U.S. Department of Energy Richland Operations Office is proposing to close the Nonradioactive Dangerous Waste Landfill (NRDWL) and Solid Waste Landfill (SWL) located in the 600 Area of the Hanford Site. The closure of the NRDWL/SWL entails the construction of an evapotranspiration cover over the landfill. This cover would consist of a 3-foot (1-meter) engineered layer of fine-grained soil, modified with 15 percent by weight pea gravel to form an erosion-resistant topsoil that will sustain native vegetation. The area targeted for silt-loam borrow soil sits in Area C, located in the northern central portion of the Fitzner/Eberhardt Arid Lands Ecology (ALE) Reserve Unit. The pea gravel used for the mixture will be obtained from both off-site commercial sources and an active gravel pit (Pit #6) located just west of the 300 Area of the Hanford Site. Materials for the cover will be transported along Army Loop Road, which runs from Beloit Avenue (near the Rattlesnake Barricade) east-northeast to the NRDWL/SWL, ending at State Route 4. Upgrades to Army Loop Road are necessary to facilitate safe bidirectional hauling traffic. This report documents a cultural resources review of the proposed activity, conducted according to Section 106 of the National Historic Preservation Act of 1966.

  2. Studies on radionuclide concentration along the Northern Coast of Krusadai Island

    International Nuclear Information System (INIS)

    Krusadai Island - The Biologist's Paradise, is situated in Gulf of Mannar (GaM) near Rameswaram of Tamilnadu, India. It has been recognized as Ecological sensitive area under Coastal regulation zone notification 1991 because these area act as the breeding zone for a variety of marine species, most of which are consumed by human population. Above all Govt. of India and Govt. of Tamil Nadu jointly declared Gulf of Mannar as Marine National Park under Wildlife (Protection) Act 1972. So it is essential to have a periodic radiological survey in this area in order to check the concentrations of various radionuclide. Apart from this 2004 Tsunami had many devastating effects along the coastal Tamil Nadu. GOM (Especially Rameswaram coast) didn't suffer a lot due to the barricade-like protection given by the island nation Sri Lanka. But reports suggest that northeastern part of the Krusadai Island had noticeable effects due to Tsunami, which interests to study this area. Current study is a preliminary radioactive report on the northern part of the Krusadai Island

    Previously we have deciphered the antifungal effect of sesamol (Ses), a phenolic compound obtained from sesame oil, against human fungal pathogen Candida albicans. To gain deeper insights into the possible mechanisms involved, transcription profiling was done in presence of Ses which revealed various targets through which Ses was barricading the growth of C. albicans. We observed that Ses perturbs membrane integrity confirming our previous observations and displayed disrupted plasma membrane ATPase activity. We further investigated that Ses leads to inhibited morphological transition, biofilm formation and epithelial cell adhesion which are significant virulence attributes required for pathogenesis. Interestingly, Ses also causes amendment in iron homeostasis as revealed by hypersensitivity under iron deprivation, ferroxidase assay to estimate iron levels and concomitant upregulation of FTR2, a high affinity iron transporter. Finally we assessed that Ses causes defect in mitochondrial functioning and DNA repair mechanism. Together, being source of consumable natural product, further studies on Ses are warranted so that it can be exploited as effective antifungal agent. PMID:27392701

    The scuttle flies (Diptera: Phoridae) are important in forensic dipterology, because of their necrophagous habit. They are amongst the first wave of insects visiting human corpses in mechanically barricaded environments; hence their immature stages are generally used for estimation of PMI. The effect of different substrates commonly used for developmental studies was studied to analyze the variation of growth of the thermophilic variety of Megaselia (M.) scalaris prevalent in India on GDM, EDM, and SMS (n = 3). One approach of PMI estimation depends on larvae collected from the crime scene and comparing them with reference data derived from larval rearing to establish PMI. Results showed that there was a significant variation in avg. length (F(2,111) = 15.79873, p = 0.000000917), width (F(2,111) = 14.60528, p = 0.00000234), and biomass (F(2,111) = 37.01727, p = 0.000000000000482) of the immature stages in the three media and the larvae grow maximally in the SMS medium. The results of the present study thus provide baseline data on the growth and developmental pattern of the Megaselia (M.) scalaris, which can be utilized in conjunction with specific geoclimatic reference data, for forensic entomological studies and also for using the phorid as a biocontrol agent of pestiferous insects.

    Since the 19th century, workers have organized in trade unions and parties to strengthen their efforts at improving workplace health and safety, job conditions, working hours, wages, job contracts, and social security. Cooperation between workers and their organizations and professionals has been instrumental in improving regulation and legislation affecting workers' health. The authors give examples of participatory research in occupational health in Denmark and Finland. The social context of workplace health promotion, particularly the role of unions and workers' safety representatives, is described in an international feasibility study. Health promotion is rife with fundamental political, socioeconomic, philosophical, ethical, gender- and ethnicity-related, psychological, and biological problems. Analysis of power and context is crucial, focusing on political systems nationally, regionally, and globally. The authors advocate defending and supporting workers and their trade unions and strengthening their influence on workplace health promotion. In the face of rapid capitalist globalization, unions represent a barricade in defense of workers' health and safety. Health promoters and related professionals are encouraged to support trade unions in their efforts to promote health for workers and other less privileged groups. PMID:11913856

    Full Text Available Human skin apart from functioning as a physical barricade to stop the entry of pathogens, also hosts innumerable commensal organisms. The skin cells and the immune system constantly interact with microbes, to maintain cutaneous homeostasis, despite the challenges offered by various environmental factors. A major environmental factor affecting the skin is ultraviolet radiation UV-R from sunlight. UV-R is well known to modulate the immune system, which can be both beneficial and deleterious. By targeting the cells and molecules within skin, UV-R can trigger the production and release of antimicrobial peptides (AMPs, affect the innate immune system and ultimately suppress the adaptive cellular immune response. This can contribute to skin carcinogenesis and the promotion of infectious agents such as herpes simplex virus and possibly others. On the other hand, a UV-established immunosuppressive environment may protect against the induction of immunologically mediated skin diseases including some of photodermatoses such as polymorphic light eruption. In this article, we share our perspective about the possibility that UV-induced immune suppression may alter the landscape of the skin's microbiome and its components. Alternatively, or in concert with this, direct UV-induced DNA and membrane damage to the microbiome may result in pathogen associated molecular patterns (PAMPs that interfere with UV-induced immune suppression.

    Magnesium (Mg) alloys have been introduced as new generation of biodegradable orthopedic materials in recent years since it has been proved that Mg is one of the main minerals required for osseous tissue revival. The main goal of the present study was to establish a desired harmony between the necessities of orthopedic patient body to Mg{sup 2+} ions and degradation rate of the Mg based implants as a new class of biodegradable/bioresorbable materials. This prospect was followed by providing a sol–gel derived nanostructured hydroxyapatite (n-HAp) coating on AZ91 alloy using dip coating technique. Phase structural analysis, morphology study, microstructure characterization, and functional group identification were performed using X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The prepared samples were immersed in simulated body fluid in order to study the formation of apatite-like precipitations, barricade properties of the n-HAp coating, and to estimate the dosage of released Mg{sup 2+} ions within a specified and limited time of implantation. Electrochemical polarization tests were carried out to evaluate and compare the corrosion behavior of the n-HAp coated and uncoated samples. The changes of the in vitro pH values were also evaluated. Results posed the noticeable capability of n-HAp coating on stabilizing alkalization behavior and improving the corrosion resistance of AZ91 alloy. It was concluded that n-HAp coated AZ91 alloy could be a good candidate as a type of biodegradable implant material for biomedical applications. - Highlights: • Nanostructured hydroxyapatite coatings were applied on Mg based alloy. • The whole corrosion process of Mg based alloy was controlled in body fluid. • This coating was able to act as a barrier against further release of Mg{sup 2+} ions. • The coating improved the stabilization of Mg alkalization behavior.

    Core hole DC-4 was completed at a depth of 3998 feet in December, 1978 by Boyles Brothers Drilling Company, Spokane, Washington, under subcontract to Fenix and Scission, Inc. The hole was cored for the US Department of Energy and the Rockwell Hanford Operations' Basalt Waste Isolation Program. Fenix and Sicsson, Inc. furnished the engineering, daily supervision of the cable tool and core drilling activities, and geological core logging for DC-4. Core hole DC-4 is located on the Hanford Site about 3 miles east of the Yakima Barricade and approximately 103 feet southwest of rotary hole DC-5, which was completed to 3990 feet in February, 1978. Hanford Site coordinates reported for hole DC-4 are north 49,385.62 feet and west 85,207.63 feet, and Washington State coordinates are north 454,468.73 feet and east 2,209,990.87 feet. No elevation survey is available for hole DC-4, but it is approximately 745 feet above mean sea level based upon the survey of hole DC-5, which has a reported elevation of 745.16 feet on the top of the 3-inch flange. The purpose of core hole DC-4 was to core drill vertically through the basalt and interbed units for stratigraphic depth determination and core collection, and to provide a borehole for hydrologic testing, cross-hole seismic shear, and pressure wave velocity studies with rotary hole DC-5. Hole DC-4 was drilled through the overburden into basalt bedrock by cable tool methods (0-623 feet) and continuously cored through the final interval (623 to 3998 feet).Core recovery was 95.8 percent of the total footage cored.

  10. High-temperature membranes for H{sub 2}S and SO{sub 2} separations. Final report

    Winnick, J.

    1995-01-01

    Electrochemical cells which separate H{sub 2}S and S0{sub 2} from hot gas streams have two important materials issues that limit their successful industrial application: (1) membranes and (2) electrodes. These were the focus of the present study. For the H{sub 2}S work, experimental analysis incorporated several membrane and electrode materials; densified zirconia provided the best matrices for entrainment of electrolytic species, ionic mobility, and a process-gas barricade hindering the capabilities of gas cross-over, alternate reactions. Electrode materials of lithiated Ni converted to NiO in-situ were successful in polishing applications; however H{sub 2}S levels >100 ppM converted the NiO cathode to a molten nickel sulfide necessitating the use of Co. Lithiated NiO for the anode material remained morphologically stable and conductive in all experimentation. High temperature electrochemical removal of H{sub 2}S from coal gasification streams has been shown on the bench scale level at the Georgia Institute of Technology utilizing the aforementioned materials. Experimental removals from 1000 ppM to 100 ppM H{sub 2}S and 100 ppM to 10 ppM H{sub 2}S proved over 90% removal with applied current was economically feasible due to high current efficiencies ({approximately}100%) and low polarizations. For the S0{sub 2}work, an extensive search was conducted for a suitable membrane material for use in the S0{sub 2} removal system. The most favorable material found was Si{sub 3}N{sub 4}, proven to be more efficient than other possible materials. New lithiated NiO electrodes were also developed and characterized, proving more stable than previously used pervoskite electrodes. The combination of these new components led to 90% removal at near 100% current efficiency over a wide range of current densities.

  11. Remembrances of Empires Past

    Directory of Open Access Journals (Sweden)

    Robert Aldrich

    2010-03-01

    Full Text Available This paper argues that the colonial legacy is ever present in contemporary Europe. For a generation, most Europeans largely tried, publicly, to forget the colonial past, or remembered it only through the rose-coloured lenses of nostalgia; now the pendulum has swung to memory of that past – even perhaps, in the views of some, to a surfeit of memory, where each group agitates for its own version of history, its own recognition in laws and ceremonies, its own commemoration in museums and monuments, the valorization or repatriation of its own art and artefacts. Word such as ‘invasion,’ ‘racism’ and ‘genocide’ are emotional terms that provoke emotional reactions. Whether leaders should apologize for wrongs of the past – and which wrongs – remains a highly sensitive issue. The ‘return of the colonial’ thus has to do with ethics and politics as well as with history, and can link to statements of apology or recognition, legislation about certain views of history, monetary compensation, repatriation of objects, and—perhaps most importantly—redefinition of national identity and policy. The colonial flags may have been lowered, but many barricades seem to have been raised. Private memories—of loss of land, of unacknowledged service, of political, economic, social and cultural disenfranchisement, but also on the other side of defeat, national castigation and self-flagellation—have been increasingly public. Monuments and museums act not only as sites of history but as venues for political agitation and forums for academic debate – differences of opinion that have spread to the streets. Empire has a long after-life.

    Full Text Available The present article is part of a dense literature – result of a perennial debate – that has polarized societies for a long time and has evident reverberations in the present. It deals with “the right to death”, trying to offer some answers referring to its existence in fact and the way in which it is perceived by different states and diverse entities with juridical nature. In the first part of the paper, it is insisted upon the right to life, so that subsequently, to speak in detail about a “right to death” and the moral and juridical implications of using such phrases. There are analyzed different states of the world found on one part or the other of the barricade in what concerns the legality of euthanasia and assisted suicide – considered the two hypostasis of the right in question. It is offered, as well, an analysis of the Convention for the Protection of Human Rights and Fundamental Freedoms, mentioning that, paradoxically, while it cannot be modified so that it allows the appearance of some new rights, it can tacitly accept the creation by some states that have adhered to it of some rights antagonistic with those presented in its text. The conclusion, is that not any liberalization movement of a social action – quantified through the request of a right – has as a direct result a progress of the respective society, especially when the action creates something diametrically opposed to some fundamental functioning norms, such as, by excellence, the granting of the protection of life of all individuals.

    Full Text Available For decades, Lebanon was war-torn by civil strife, and occupation and invasion by neighboring countries. In time, these wars have escalated in intensity from sniping, barricading streets and random shelling of residential quarters to the use of rockets, aerial bombing, and heavy artillery. Adverse mental health effects are noted in times of war with post traumatic stress disorder (PTSD as a main outcome. The aim of this study was to carry out a systematic review of published studies documenting the prevalence of PTSD in the adolescent population of Lebanon, to investigate the increase in these rates with the escalation of war intensity, and to examine PTSD determinants. A search strategy was developed for online databases (PubMed and Google Scholar between inception to the first week of January 2013. Search terms used were PTSD, adolescents and Lebanon. Eleven studies reporting PTSD in adolescents met the inclusion criteria for a total number of 5965 adolescents. Prevalence rates of PTSD ranged from 8.5% to 14.7% for the civil war, 3.7% for adolescents with sensory disabilities, 21.6% for the Grapes of Wrath War, and 15.4% to 35.0% for the 2006 July War. Some increase in PTSD rates in time is noted. Type of trauma such as bereavement, injury, house destruction, and economic problems, low self efficacy and scholastic impairment were related to PTSD. These findings may help in the development of public health policies for PTSD prevention and treatment for the protection of adolescents from war atrocities and their consequences.

    Full Text Available Does the Constitution protect a citizen’s intra-state travel (within a state from unjustified state prohibition? To date, the Supreme Court has not ruled directly on the issue, and many federal courts believe that the right to intrastate travel is not constitutionally protected. This Article explores the constitutional right of intra-state travel that is free from wrongful state infringement along public roadways by law-abiding citizens. Using critical legal history, this Article poses that federal courts’ denial of the right to intrastate travel consciously or unconsciously reflects the antebellum, Southern legal doctrine of people as property, which regulated the travel of enslaved African descendants.The constitutionality of intra-state travel arose most recently during the Hurricane Katrina Crisis when the City of Greta, Louisiana police barricaded a federal highway, denying would-be evacuees the ability to flee from the flooding City of New Orleans. In an ensuing action for infringement of the would-be evacuees’ constitutional right to intra-state travel, Federal District Judge Mary Ann Vial Lemmon dismissed the matter in Dickerson v. City of Gretna, holding that “[w]hile there is no doubt that a fundamental right of interstate travel exists, the Supreme Court has not ruled on whether a right of intra[-]state travel exists. This Court declines to find that there is a fundamental right to intra[-]state travel.” The Fifth Circuit affirmed the ruling.This Article recommends that when federal courts assess whether there is a constitutional right to intra-state travel, they should embrace the American paradigm of liberty and abandon the antebellum, Southern paradigm of enslavement. Consistent with Professor Derrick Bell’s “interestconvergence” principle, all Americans benefit when the Constitution protects the human rights of the least powerful American.

    Full Text Available he agreement of cooperation, good neighbourly relations and friendship signed at Moscow on the 5th of April 1991 between Romania and the Soviet Union replaced the old Treaty, concluded in 1970. According to the new document, Romania and the USSR considered themselves, in their mutual relations, as well as in the whole international community, in any event, as being States buddy. In this context, although the media have made the claim that the Treaty would be contrary to the interests of Romania and Moldovan SSR, President Ion Iliescu denied the charges, stressing that the Treaty was keeping in mind the processes affirming the sovereignty in the Soviet republics. On the other hand, the President of the Moldovan SSR, Mircea Snegur, declared that thanks to the specific relationships between Chişinău and Bucharest, the direct relationships with the Romanian State had been established even in the absence of the clause relating to Romania's ties with the Republics of the Soviet Union. The Romanian-Soviet Treaty has had a devastating impact on the image of Romania, on her political leaders, in the European capitals and among public opinion on both sides of the Prut River. In Chişinău, the reactions of the public opinion and of the national political forces were extremely vigorous. On 24 April 1991, the members and the sympathizers of the Popular Front also issued a Declaration concerning the Romanian-Soviet Treaty, in which the Treaty was described as being inappropriate, and was considered a challenging act to the fight for independence of Moldova. On the other side of the political barricade, The Communist Party from Moldova has warmly welcomed the signing of the Romanian-Soviet Treaty. Thus, the C.C. Secretary of the CPM, Ion Guţu, considered that the document signed by Presidents Iliescu and Gorbachev removed the odious scenario of the Union. However, the implosion of the Soviet Empire has removed permanently from the agenda the question of

    Since 2012 we have carried out extensive multibeam bathymetric and backscatter surveys in coastal waters of eastern Baffin Island, supplemented by sub-bottom imaging and coring. Shore-zone surveys have been undertaken in proximity to the communities of Iqaluit and Qikiqtarjuaq, following earlier work in Clyde River. These support benthic habitat mapping, geological exploration, analysis of past and present sea-level trends, and assessment of coastal hazards relating to climate change and seabed instability. Outputs include a seamless topographic-bathymetric digital elevation model (DEM) of extensive boulder-strewn tidal flats in the large tidal-range setting at Iqaluit, supporting analysis of coastal flooding, wave run-up, and sea-ice impacts on a rapidly developing urban waterfront in the context of climate change. Seabed mapping of inner Frobisher Bay seaward of Iqaluit reveals a potential local tsunami hazard in widespread submarine slope failures, the triggers, magnitudes, and ages of which are the subject of ongoing research. In fjords of the Cumberland Peninsula, this project has mapped numerous submerged delta terraces at 19 to 45 m present water depth. These attest to an early postglacial submerged shoreline, displaced by glacial-isostatic adjustment. It rises linearly over a distance of 100 km east to west, where a submerged boulder barricade on a -16 m shoreline was discovered at a proposed port site in Broughton Channel near Qikiqtarjuaq. Palaeotopographic mapping using the multibeam data revealed an enclosed estuarine environment quite different from the present-day open passage swept by tidal currents. At Clyde River, combined seabed and onshore DEMs with geohazard mapping provided foundation data for community assessment and planning under a local knowledge co-production initiative. The geohazard work identified portions of the town-site more vulnerable to both coastal flooding and potential thaw subsidence, while the shallow delta terrace suggested a

  18. Demolitions of the Savannah River Site's concentrator and finishing facilities

    International Nuclear Information System (INIS)

    The Savannah River Site (SRS) has produced Special Nuclear Materials (SNMs) starting in the early 1950's to the mid 1970's for the Atomic Energy Commission (AEC) and from the mid 1970's to the present for the Department of Energy (DOE). In that time, over 1,000 facilities have been built in the sixteen operational areas of the eight hundred square kilometer site. Over the years, many of the facilities have been dispositioned by the DOE as inactive. In FY-03, DOE identified two hundred and forty-seven (inactive or soon to be inactive) facilities that required demolition. Demolition work was scheduled to start in FY-04 and be completed in the first quarter of FY-07. Two-hundred and thirty-nine of these facilities have been demolished employing Routine demolition techniques. This presentation reviews and discusses two of the eight Non-Routine demolitions Facilities, 420-D 'The Concentrator Facility', and 421-D 'The Finishing Facility'. Facilities 420-D and 421-D were toppled by attaching rigging from the structural steel building frame to bulldozers and toppling the facilities over. The greatest advantage of this method is that it employs equipment that is on hand at SRS, saving time on locating and leasing offsite equipment as well as operator training. In addition, although the toppled structure does not land in the original facilities footprint, it does land in a contained area that is easily barricaded to prevent access during the operation. There are several disadvantages. First, there must be adequate area for the structure to topple into. Also if the wire rope size required to topple the structure is larger than two in., the ropes become extremely difficult to work with. Lastly, the yield strength of steel members is guaranteed by the manufacturer as a minimum strength, so its ultimate strength is unknown. This requires extremely conservative specifications sizing the bulldozers and any rigging equipment employed. Two hundred and forty-seven facilities have

    Objective To investigate availability of deep freeze storedallogenic tendon with sheath grafting in repairing the tendon and sheath defect in the Ⅱarea of flexor digitorum tendon. Methods Sixty chickens with tendon and sheath defect were divided into 2 groups randomly, group A was treated with allogenic grafting and group B was treated with autogenic grafting, these two groups were divided into two subgroups respectively, they were, group A1 allogenic tendon with whole sheath grafting, group A2 allogenic tendon with partial sheath grafting, group B1 autogenic tendon with whole sheath grafting and group B2 autogenic tendon with whole sheath grafting. All the allogenic grafts were treated by deep freeze. Histomorphological study, histoimmunological study and slipping function of the grafts were measured after operation. Results In group A1 and B1, the local reaction was sever, the nutrition of tendon graft was barricaded by the whole sheath resulting in adhesion, degeneration and necrosis. In group A2 and B2, the tendon graft healed well and little adhesion existed between tendon and sheath. The results showed that there were significant differences between tendon grafting with whole sheath and tendon grafting with partial sheath. Conclusion Deep freeze store can reduce the immunogenicity of allogenic tendon with sheath. Allogenic tendon with partial sheath grafting can be used as a new biological material for repairing the tendon and sheath defect.%目的 探讨深低温冷冻带腱鞘异体肌腱移植的可行性,为屈指肌腱Ⅱ区腱鞘和肌腱缺损重建提供新的修复材料。方法 将60只北京双A鸡随机分为两组,A组为异体移植,B组为自体移植。每组再分两个亚组,A1全鞘异体肌腱移植;A2部分鞘(滑车A2~A4)异体肌腱移植;B1全鞘自体肌腱移植;B2部分鞘(滑车A2~A4)自体肌腱移植。异体材料采用深低温处理,移植术后进行组织形态学、移植免疫学及肌

    prostate-specific antigen, pathologic Gleason score, and pathologic T stage in the multivariate model. Logistic regression for PSM site revealed no significant correlation of apex PSM with extraprostatic extension location, while base PSM was associated with increased odds of anterior (OR 2.513, 95% CI 1.425–4.430, p = 0.001) and lateral (OR 2.715, 95% CI 1.735–4.250, p<0.001) extraprostatic extension. Conclusion Extension into the extraprostatic tissue on some specific locations do not share the same recur risk due to the different anatomical structures surrounding the organ. Anterior and lateral EPEs are prone to leave PSM on the base of the prostate, probably because of the lack of anatomical barricades slowing down the direct invasion process. More study on the pattern of spread of the tumors found to have extraprostatic extension is suggested for optimal planning of the operation extent and of the adjuvant radiotherapy. PMID:27391650

  1. HE Machining Complex and Support Buildings Deactivation and Decommissioning Project at the Pantex Plant

    International Nuclear Information System (INIS)

    This paper describes the issues related to the deactivation and decommissioning of a very unique building at the Department of Energy's Pantex Plant located in Amarillo, TX. Building 12-24 was unique in the fact that it had a number of obstacles that have not been previously addressed in the deactivation and decommissioning of a single structure such as asbestos, beryllium, possible radionuclide contamination, lead paint, heavily reinforced concrete walls, and high explosive (HE) contamination inside and out. To date, the building has been razed and the majority of all equipment has been disposed of. Remaining work includes concrete and soil debris removal, earthen barricade removal, and site leveling. Pantex Site Summary: Pantex Plant is America's only nuclear weapons assembly and disassembly facility. Located on the High Plains of the Texas Panhandle, 17 miles northeast of Amarillo, Pantex is centered on a 16,000-acre site just north of U. S. Highway 60 in Carson County. The Pantex Plant industrial operations are conducted for the DOE by a management and operating contractor (BWXT Pantex), and Sandia National Laboratory. DOE owns approximately 9,100 acres at the Pantex Plant. Just over 2,000 acres of the DOE-owned property are used for industrial operations at Pantex Plant excluding the burning ground, firing sites and other outlying areas. The burning ground and firing sites occupy approximately 489 acres. Remaining DOE-owned land serves DOE safety and security purposes. DOE also owns Pantex Lake, a detached piece of property approximately 4 km (2.5 mi) northeast of the main Plant site that comprises 1,077 acres; the playa lake-bed itself occupying approximately 800 acres. Currently no government industrial operations are conducted at the Pantex Lake property. Seventy-six kilometers (47 mi) of roads exist within the Pantex Plant boundaries. Project Summary: Facilities are deactivated and decommissioned (D and D) when there is no longer a mission for them or they

    Semi interpenetrating polymer networks (s-IPN) hydrogels composed of poly(vinyl acohol) (PVA), poly(4-acetyl acryloyl ethyl acetate-co-acrylic acid) [P(AAEA-co-AA)] were synthesized via solution polymerization using acrylic acid (AA), 4-acetyl acryloyl ethyl acetate (AAEA) and PVA. Foutier-transform infrared (FT-IR) was used to confirm the chemical structure of the s-IPN hydrogels. The resuits showed that the AAEA mainly existed as enol form, making the peak of C--O stretching in the IR spectra of PVA-P(AAEA-co-AA) flow to low wave numbers. This is attributed to the formation of strong hydrogen bonds between PVA, PAA and PAAEA. SEM macrographs revealed that PVA impenetrated into the P(AAEA-co-AA) ploymer networks homogeneously, and barricaded the phase separation of the hydrogels. XRD analyses showed that the hydrogels formed perfect s-IPN structure when the dosage of PVA was low. However, when the dosage of PVA was high, PVA could not impenetrate in P(AAEA-co-AA) ploymer networks homogeneously, making the crystallization of PVA increase significantly. The volume phase transition temperature (VPTT) of the s-IPN hydrogels was determined by their respective DSC ther- mograms of swollen hydrogel specimens. The results showed that the VPTT of the hydrogels ranged from 54.0 to 57.8℃, and increased with the increasing dosage of PVA. The stress strength of s-IPN hydrogels was studied, the results showed that the s-IPN structure formed between PVA and P(AAEA-co-AA) improved the strength of the hydrogels significantly, and the maximum stress strength of the hydrogel was about 8.4 MPa. The temperature sensitivity of the s-IPN hydrogels was also investigated, the results showed that the hydrogels exhibited excellent temperature sensitivity. When the temperature was lower than VPTT, the hydrogels kept at a swelling state, but when the temperature was higher than VPTT, the hydrogels des- welled evidently.%以4-乙酰基丙
